An internal coating spray machine for cans or containers having spray gun(s) with nozzle(s) which may be automatically cleaned. Each spray gun has a clamp bracket which carries an actuator carrying a cleaning brush. When the actuator is actuated, it carries the brush from a first location (out of the way) to a second location in which the brush moves across the nozzle, cleaning it. The IC machine HMI (human-machine interface) may have a manually actuated control, for example, a button or soft button, which pauses can spraying and carries out a cleaning cycle. It may also use the low infeed sensor of the IC spray machine to detect when cans will be momentarily delayed coming in, and automatically clean during that small hiatus. A timer automatically initiates a cleaning cycle if one has not otherwise happened in a given time X.sub.t.

Cleaning air knife elements are assembled in a parallel orientation inside a housing enclosing the air knife assembly and in fluid communication with a compressed air source. In certain embodiments, the air knife elements are spaced apart a distance that orients the cleaning air knife discharge slots directly parallel and in line with the slots of the air nozzle or bar to be cleaned. Air discharging from the air knife discharge slots passes through the discharge slots of the air nozzle to be cleaned, dislodging dust and friable solid buildup from the air nozzle slots. Additionally, the cleaning air jet enters the air nozzle body, further dislodging dust and friable solids from the internal passages of the air nozzle inside the air nozzle body.

A sealant applying device and a working method thereof, and a sealant applying apparatus are disclosed. The sealant applying device includes a nozzle; the nozzle includes an air inlet portion and a sealant outflow portion, a switch plate is arranged below the sealant outflow portion, the switch plate includes a plate body configured to horizontally move between a first state and a second state, one end of the plate body is provided with a through hole, and a discharge portion is provided at a position corresponding to the through hole and on a side of the plate body facing away from the sealant outflow portion.

The invention generally relates to a surface treatment distribution apparatus and spray assembly apparatus method capable of applying a variety of surface treatments, for example mastic surface treatments, to a variety of highways, roadways and other asphalt surfaces of variable shapes and sizes. The invention generally includes a tank, pumps, operator station, control inputs, filter assemblies, spray bar and self cleaning spray tip assemblies. Each spray tip assembly includes a self cleaning functionality whereby the operator may remove any debris or clogging material from one or more spray tips with a pneumatically actuated plunger located in the spray tip assembly that acts to force the debris or blockage out of the spray tip. The plunger retracts after actuation and the spray tip assembly is then ready to resume spray operations as desired by the operator.

A rubber fixing apparatus and a coater are provided. The rubber fixing apparatus includes: a storing device, in which a cavity configured to receive at least one rubber and an outlet communicated with the cavity are provided; and a fixing structure provided on the storing device and outside the cavity. The rubber is moved from the cavity through the outlet in a first direction and is fixed to the fixing structure.

A device for working ground surfaces or roadways comprising a machine frame and a working drum in a drum housing arranged at said machine frame, where no less than one spraying device extending parallel to the working drum and featuring several outlet nozzles for spraying agents arranged next to one another and directed towards the working drum is arranged at the drum housing, where the outlet nozzles comprise one each drivable closing mechanism with a closing element which, in an open position, fully uncovers the nozzle channel of the outlet nozzle and, in a closed position, closes the nozzle channel. A controller drives the closing mechanisms, with the outlet nozzles and the related closing elements being adapted to one another in such a fashion that the flow cross-section in the outlet nozzle is variable in accordance with the position of the closing element on a specified path between the open position and closed position.

A nozzle auto-cleaning device and a nozzle auto-cleaning method are disclosed. The nozzle auto-cleaning device includes a base and a cleaning piece feeding unit disposed on the base, the base has a bearing surface on which the cleaning piece feeding unit is disposed, the cleaning piece feeding unit is configured to transport a cleaning piece installed inside the nozzle auto-cleaning device along a first direction intersected with the bearing surface so that a first portion of the cleaning piece is protruded in a direction away from the bearing surface and inserted into a nozzle, and the base is configured to move along at least one direction of the first direction, as well as a second direction and a third direction intersected in a plane of the bearing surface, so as to drive the first portion of the cleaning piece to move inside the nozzle.

Systems and methods for inspecting and cleaning a nozzle of a dispenser are disclosed. The systems may include a platform supporting a cleaning substrate. The cleaning substrate may have a plurality of hook structures configured to remove a material from the nozzle. The systems may also include a camera configured to capture an image of the nozzle and a controller configured to control the system. The methods may include providing a cleaning substrate having a plurality of hook structures, and moving at least one of the nozzle and the cleaning substrate relative to the other to remove a material from the nozzle. The methods may also include capturing an image of the nozzle after dispensing with a camera, processing the image to generate a value, utilizing the value to determine if the nozzle should be cleaned, and if the determination is that the nozzle should be cleaned, cleaning the nozzle.
