DETAILED DESCRIPTION

[0024] Next, a detailed explanation will be given for exemplary embodiments with reference to the drawings. In the following description of the drawings, a same or like reference sign is given to a same or like part. The drawings schematically represent configurations according to the exemplary embodiments of the present invention. Furthermore, the exemplary embodiments of the present invention described below are examples and may be modified as appropriate as long as the nature of the present invention is not altered.

[0025] FIGS. 1-4 are schematic diagrams of a pre-coated bottom cover combination machine for tile carpet according to preferred embodiments of the present disclosure. The exemplary pre-coated bottom cover combination machine for tile carpet includes a carpet surface pre-coated processing line 1 and a back bottom cover processing line 2 according to the present disclosure. The carpet surface pre-coated processing line 1 includes blank carpet reel device 3, blank carpet storage rack 4, antifouling gluing device 5, pre-coated drying and heating line 6, pre-coated carpet storage rack 7, U-type carpet storage box 8 in sequence according to the blank carpet pre-coated processing order, and then it is fed into the composite device of bottom back and carpet surface 9 in the back bottom cover processing line 2 for bottom cover processing. The back bottom cover processing line 2 includes drive device 11 for driving the carpet belt 10 to move, black material feeding and automatic control device 12, scraper 13, white material feeding and automatic control device 14, composite device of bottom back and carpet surface 9, bottom back plasticizing and heating line 15, embossing device 16, carpet body water-cooled plate 17, carpet body water-cooled roller 18, carpet storage rack 19, deviation correction device 20, dicing machine 21, inspection table 22. The carpet surface pre-coated processing line 1 is located above the back bottom cover processing line 2. The pre-coated drying and heating line 6 in the carpet surface pre-coated processing line 1 and the bottom back plasticizing and heating line 15 in the back bottom cover processing line 2 are performed in the same heating oven 23, wherein the upper layer of the heating oven 23 is pre-coated drying and heating line 6, and the bottom of the pre-coated drying and heating line 6 is bottom back plasticizing and heating line 15. Metal thermal conductive plate or mesh with through-hole 24, such as aluminum plate and steel mesh etc, is used to separate between the pre-coated drying and heating line 6 and the bottom back plasticizing and heating line 15, in order to prevent staple fibers and other scrap rubber on the surface of carpet which is in the process of pre-coated drying and heating from falling onto the carpet surface which is in the process of plasticizing. Three to five dehumidifier air fans 25 are provided in the heating oven 23 and the water vapor in the heating oven 23 is withdrawn to the outside. The heating oven 23 consists of a plurality of single ovens 26 in series. The pre-coated drying and heating line 6 is heated using the natural gas burner 27, and the pre-coated dried carpet surface 28 is heated up via the heating fan air duct 29.

[0026] The bottom surface of the bottom back which is bottom covered is moved linearly above the metal heating plate 30 to generate heat in the bottom back plasticizing and heating line 15. The metal heating plate 30 is a reciprocating oil groove on the plate, forming an in/out pipe, into which hot oil of 165 ° C. to 185 ° C. is injected. Furthermore, the pre-coated carpet roll device 31 could be disposed at the back of the U-type carpet storage box 8 and be used in the carpet surface pre-coated processing line 1 for completing the process that the pre-coated dried carpet surface 28 is led to the pre-coated carpet roll device 31 through guide roller 32 and is rolled directly to a barrel shape for later use. An unwinding device 33 of the pre-coated roll carpet is disposed between the pre-coated carpet roll device 31 and U-type carpet storage box 8. The back bottom cover processing line 2 utilizes other carpet surfaces that have been pre-coated for bottom cover process, rather than using the pre-coated dried carpet surface 28 that is being processed on the carpet surface pre-coated processing line 1, as shown in FIG. 5.

[0027] According to the above embodiments of the pre-coated bottom cover combination machine for tile carpet, the pre-coated drying and heating line in the carpet surface pre-coated processing line and the bottom back plasticizing and heating line in the back bottom cover processing line are performed in the same heating oven, so that the remaining heat in the respective heating processes can be utilized by each other. The working temperature on the upper level is lower than that on the lower level, and residual heat after the bottom back on the lower level being plasticized and heated rises to supplement for the upper pre-coated drying and heating. According to the theoretical measurement, its thermal energy saves about ⅓ than that of the two lines being heated alone respectively. In addition, due to the fact that the pre-coated processing line is imposed above the back bottom cover processing line, the length of processing line is shortened by about 50 meters, which is 42.7% shorter than the overall length of the original independent processing line (117 meters), the areas of workshop occupied by the processing equipments is reduced, and the manufacturing cost of tile carpets as well as bottom cover processing line is reduced. On the use of labor, four less people are required by using this combination machine than that by using original pre-coated line and the bottom cover line. It also eliminates the waste of carpet surface joints and labor use, since it avoids the original process that the processed carpet surface is rolled first and then the rolled carpet surface is moved to bottom cover processing line for joint and bottom cover processing. In use, the technical solutions of the present invention can be as follows according to the needs of production orders such as product material, color varieties and other flexible use:

[0028] 1. Carpet surface pre-coated processing line and back bottom cover processing line are enabled at the same time, and the carpet surface completed in the carpet surface pre-coated processing line is transferred directly into the back bottom cover processing line. The tile carpet for bottom cover processing is shown in FIG. 1, pre-coated drying and heating line and bottom back plasticizing and heating line are enabled at the same time, and the heat in both of the heating lines can be recycled.

[0029] 2. Carpet surface pre-coated processing line and back bottom cover processing line are enabled at the same time, and the carpet surface completed in the carpet surface pre-coated processing line is not transferred directly into the back bottom cover processing line. However, the pre-coated carpet surface completed in the carpet surface pre-coated processing line is rolled directly into a barrel shape for later use. The bottom cover processing line utilizes other carpet surfaces that have been pre-coated for bottom cover process, rather than using the pre-coated carpet surface being processed in the carpet surface pre-coated processing line, as shown in FIG. 2. The pre-coated drying and heating line and bottom back plasticizing and heating line are enabled at the same time, and the heat in both of the heating lines can be recycled.

[0030] 3. Carpet pre-coated processing line works independently, and only the pre-coated drying and heating line is enabled. The completed carpet surface is rolled directly into a barrel shape for later use. The back bottom cover processing line is shut down, and the bottom back plasticizing and heating line is not enabled, so there is no mutual use of heat.

[0031] 4. Carpet pre-coated processing line is shut down, and the pre-coated drying and heating line is not enabled. The back bottom cover processing line works independently, and only the bottom back plasticizing and heating line is enabled, so there is no mutual use of heat.

[0032] The present invention can meet the requirements of: good continuity in pre-coating and bottom covering process, energy recycling in heating and drying, compact structure, labor saving, shortening the time of carpet surface pre-coating and back bottom covering, reducing area of workshop occupied by pre-coating line and bottom covering line, significantly reducing the manufacturing cost of tile carpets.
