A paper shredder bin-full sensor with a push bar, a conductive element coupled to the push bar, a sensing contact assembly normally set apart from the conductive element, and a signaling contact coupled to the sensing contact assembly. Sensor includes a push bar sweeper between the conductive element and the push bar, and a biasing element coupled to the push bar sweeper, the biasing element elastically resists the shredded material force. A predetermined shredded material force presses the push bar, causing the conductive element to couple to the sensing contact assembly, in turn causing a waste bin-full signal to emanate. Push bar can be articulated and non-articulated. Articulated push bars include upper and lower push bars, and respective tensioning element connecting the respective upper and lower push bars. Lower push bar is extended from upper push bar. Paper shredder can have articulated or non-articulated push bars.

A comminuting apparatus for comminuting comminution stock like recyclable material, waste and product residues, including a comminuting rotor mounted rotatably to a machine frame and having comminuting tools arranged thereon, a receiving region for receiving comminution stock and a feed device having a ram device which is moveable in the direction towards the comminuting rotor by a drive device and which is adapted for feeding comminution stock to the comminuting rotor. The comminuting apparatus is distinguished in that the drive device of the feed device has at least two spaced electric actuators which are controlled by a control device and which are connected at the drive output side by a transverse member, wherein the transverse member is operatively connected to the ram device by a resilient damping device.

A electronic grinder includes a base and a cup, the cup defining a pulverization chamber. A drive shaft connected to an electric motor terminates inside the pulverization chamber at a blade group. The blade group is magnetically removable from the end of the drive shaft for easy cleaning and replacement. The end of the cup opposite from the base in includes a fixed ring and a moveable cap that rotates or swivels about a pin connecting the two components for easy access to the contents of the pulverization chamber. The electric motor is controlled by a microcontroller operable by a power button and a control button. An inductive switch configured as a triggering member is disposed between the base and cup to detect whether the two components are connected in order to prevent inadvertent use of the grinder.

A food waste disposer includes a food conveying section, a grind and discharge section and a motor section used for driving the grind and discharge section to execute a grinding process. The motor section includes a universal motor, the universal motor includes a control device for controlling the output of the universal motor, and the control device includes a rectifier bridge circuit module for converting an AC power signal into a DC power signal.

The present invention relates to the field of garbage landfill. The present invention discloses a classified landfill device and method for garbage landfills, and the problem solved by the present invention is that the device proposed in the above background absorbs metals in the garbage using a magnet, but when the surface of the magnet has absorbed a large amount of metal, the device needs to be closed to treat the metal adsorbed on the surface of the magnet. The present invention comprises a screening mechanism, crushing mechanism and discharge mechanism. According to the classified landfill device and method for garbage landfill, the second crushing knife is set at an angle to divert the falling garbage to the front and rear sides, so that the two first crushing knives and the second crushing knife cooperate to crush the garbage respectively to avoid excessive accumulation of garbage.

The present invention involves a collapsible and disposable container that is inserted into a paper shredder to catch the shredded paper fragments. The disposable container has a relatively narrow slot-shaped opening having a length less than the longest dimension of the top of the container. A pair of counter-rotating rollers is supplied to compact the paper fragments and feed them through the slot and into the waste container. Various sensor systems, some constructed from conductive ink are used with and within the disposable container.

A pump having a cutting wheel (20) and a pre-cutter (26) driven by a shaft portion (24) that projects axially from the cutting wheel (20) and has a plurality of wings (28) that extend radially from the shaft portion (24), wherein the wings (28) differ in their axial arrangement on the shaft portion (24).

A defibrating device and sheet manufacturing apparatus attract and remove metal fragments when metal fragments are mixed with fibrous material. A defibrating device has a main unit with a defibration section configured to defibrate fibrous material, and a swirl section configured to produce a rotational current, and by the rotational current cause the fibrous material to rotate and flow into the defibration section. The main unit has a magnet unit that is disposed to the swirl section, and has a magnet that attracts by magnetic force metal fragments conveyed with the fibrous material to the swirl section.

The present invention discloses an automatic paper feeding method for a paper shredder and a paper shredder, including a step of disposing paper, a step of pressing paper, a step of automatically feeding paper continuously, and a step of shredding paper. The paper sheets to be shredded entering the automatic paper feeding channel are superimposed partially; the paper disposing mechanism and the automatic paper feeding channel of the paper shredder are located at two sides of the paper rolling device respectively; the paper rolling device is located at least at the position above the lower end portion of the paper disposing area/paper sheets to be shredded. In the present invention, the paper sheets to be shredded conveyed to the automatic paper feeding channel are superimposed partially; during shredding, the shredding cutter shreds a plurality of paper sheets to be shredded at a time, with a higher feed speed and an increased shred speed. Besides, the automatic feed speed can be adjusted. The present invention has an intelligent paper feeding function, which effectively prevents the overload during the automatic paper feeding and the automatic shredding.

A comminuting machine for comminuting material includes a machine frame, a comminuting rotor rotatably mounted on the machine frame, and a material feed area. The material feed area has a wall section over which the material to be comminuted can be supplied to the comminuting rotor and which is designed to be stationary during a comminuting operation of the comminuting machine and can be pivoted about a rotational axis during a maintenance operation of the comminuting machine. Because the rotational axis is designed to be releasably lockable, a second releasably lockable rotational axis is provided together with the first rotational axis, and the wall section of the material feed area can selectively be pivoted about the first or second rotational axis during the maintenance operation of the comminuting machine.
