摘要:
A system for controlling the rotation speed of a shredder motor is disclosed. It consists of a bridge rectifier circuit, a forward/reverse controlling switch, a motor speed switch, and AC motor coils. By changing a switch, it is possible to activate the following four modes: forward fast, reverse fast, forward slow, and reverse slow. A user can thus operate a shredder at high torque and low rotation speed or high rotation speed and low torque depending on the number of sheets to be shredded.

This specification discloses a shredder having a safety knob switch, which is a knob control lock mechanism protruding from its housing. The lock mechanism restricts the switching of the switch. When the switch is in the off position, it is locked and prevented from moving arbitrarily. The lock state is released by imposing a torque on the knob, turning the knob to the auto or rev position. This prevents children from playing with the shredder switch and damaging the machine or getting hurt.

A trash bin of the shredder consists of an inner bin and an outer bin. When the user inserts the inner bin into the outer bin, a bolt assembly combines the inner bin and the outer bin. An energy storing element of a pushing mechanism stores energy to push the inner bin out. The user can trigger the bolt assembly by depressing or stepping to release the energy stored in the energy storing element. The inner bin automatically jumps out for the user to clean trash paper therein.

The invention discloses a touch-stop safety device for the shredder opening. A protection board is pivotally installed on both sides of the opening of a shredder housing. The protection board is adjacent to the switch. When the protection board is under a pressure caused by an inserted finger, it rotates clockwise and touches the switch to power off the shredder. The shredding blades thus stop rotating so that the user is not hurt.

This specification discloses a shredder paper passage with a narrower neck part. From top down, the shredder paper passage has a first passage and a second passage, both in a horn shape. The intersection of the two passages forms the narrowed neck part. When the user's fingers are inserted into the paper passage, they are stopped by the narrower neck part. This protects the user from getting hurt.

The present invention relates to a round undulating blade for shredder, where a sheet metal is integrally formed into a round undulating blade to serve as the blades for constructing a blade module. The blade includes: a periphery; an undulating blade flank including at least two cambers having a first curvature and at least two cambers having a second curvature alternatively arranged with respect to the cambers having the first curvature; and hooked edges formed on the periphery of the cambers having the first curvature, wherein the undulating blade flank of the blade serves to cut paper along a longitudinal direction to form paper strips having double-tapering end, and the hooked edges serve to cut the strips along a horizontal direction into paper chips. These characteristics help to reduce the manufacturing cost, reduce the motor load and power consumption, to thereby enhance the market competitiveness.

An automated container loader for mounting to the side of a vehicle adapted for collecting the contents of curbside residential waste containers. The vehicle has a vehicle body longitudinally attached to the vehicle chassis. The automated container loader is attached to the vehicle chassis by a slide and positioned adjacent the side of the vehicle body. The container loader is equipped with a lift arm having a gripping element having a gripper housing having an opposing pair of gripping jaws. The gripping jaws are pivotally attached to the gripper housing on opposite sides to their respective arms, thereby creating a cross-pivoting arrangement. The distance between the free ends of the gripping jaws is thereby reduced when in the open position. The cross-pivoting arrangement further allows the container loader to have a thin overall width, accomplished through use of a non-folding single-section gripping jaw.

The present invention discloses a shredder which does not waste energy in standby mode. Power is applied to the components of the shredder only when material to be shredded is inserted into the shredder throat or when the unit is switched into reverse to clear a jam in the shredder.

The disclosed can presser has a movable pressing board between the front and back fixing boards of a frame. It further has a driving component to make the movable pressing board perform a reciprocal displacement between the front and back fixing boards. The can presser uses the space between the front fixing board of the frame and the moving pressing board as the empty can storage space. As the moving pressing board displaces toward the front fixing board to a stop point, the empty can is gradually squeezed to reduce its size. Finally, the driving component brings the movable pressing board backward toward the back fixing board for the squeezed empty can to be taken out.
