Description

Technical Field

[0001] The invention relates to the technical field of recycling crushers, in particular to a plastic product recycling crusher. Background Art

[0002] Plastic crusher, also known as plastic pulverizer, is mainly used to crush various plastics and rubbers such as plastic profiles, tubes, rods, wires, films, and waste rubber products. The pellets can be directly used for extruders or injection molding, or they can be recycled through basic granulation. Another type of plastic crusher is the peripheral equipment of the injection molding machine, which can crush and recycle defective products and nozzle materials produced by the injection molding machine;

[0003] For example, a plastic product recycling crusher such as "CN117301362B" aims at the problems raised in the background technology that the input amount of waste is difficult to control, the crushing structure occupies a large space, and the unloading method has great limitations. The following scheme is now proposed, including a feed bin, a crushing chamber is welded to the outer wall of the bottom of the feed bin, and a feed amount control mechanism is arranged on the inner wall of the feed bin. In the feed amount control mechanism of the present invention, the amount of waste can always be kept within a reasonable range, preventing the waste from being squeezed out, ensuring the crushing efficiency of the crusher, and effectively reducing the operating load of the crushing device. In the graded crushing mechanism, the space occupied is smaller, the crushing method is more reasonable, and the cost of equipment operation is effectively reduced. In the discharge mechanism, the discharge selectivity is more, and the discharge pipe can be rotated along the connection position with the blower to adjust the discharge position of the discharge pipe, which greatly improves the convenience of recycling waste in the recycling box;

[0004] In the above patent, a conveyor belt is used to guide the plastic into the receiving bin for pre-stacking during loading, and then the plastic is put into the feeding bin along the receiving bin. During this process, the plastic will enter the space between the feeding bin and the crushing chamber, and a certain amount of plastic will be accumulated on the crushing disk. The continuous accumulation of plastic will push the upper floating plate up. When the floating plate moves up, the motor drives the baffle plate to rotate and close. When the floating plate moves up, the accumulated plastic will add a certain pressure to the crushing disk, so that the pressure is too high when the crushing disk rotates initially, and the baffle plate is closed by rotation. After the baffle plate rotates, the multiple layers of plastic accumulated between the feeding bin and the receiving bin need to be separated. Since the uncrushed plastic is large in volume and of different lengths, it is difficult for the baffle plate to just separate the plastic accumulated at the interface between the feeding bin and the receiving bin when it rotates. Therefore, the baffle plate may squeeze the accumulated plastic to one side when it rotates, causing the baffle plate to be unable to rotate into place, thereby increasing the burden on the motor and causing damage to the motor and jamming of the baffle plate. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that after the baffle plate rotates, the multiple layers of plastic accumulated between the feeding bin and the receiving bin need to be separated, and when the floating plate moves up, the accumulated plastic will add a certain pressure to the crushing disk, causing the pressure to be too high when the crushing disk initially rotates.

[0012] As a preferred embodiment, the drainage tube is arranged in an inclined state, and one end of the drainage tube that is slidably connected to the lifting column is higher than the other end, and the lower end of the drainage tube extends to the feed end above the crushing box.

[0013] As a preferred embodiment, a bidirectional screw rod is rotatably provided at the inner center position of the base, and the bidirectional screw rod is driven to rotate by a second motor.

The bidirectional screw rod is driven to rotate by the second motor, and the lifting column and the base are only connected to each other in an up and down sliding manner, and the slider is slidably connected to the bidirectional threaded groove on the bidirectional screw rod. When the bidirectional screw rod rotates, the lifting column can be driven to move up and down, and when the lifting column moves to one end of the base, it can realize reverse movement, thereby realizing the lifting and lowering operation of the lifting column.

At this time, the sliding block also slides from the end groove to the thread groove in the other direction of the two-way thread groove, realizing the smooth downward movement of the lifting column. When the sliding block rotates one circle in the end groove, the lifting column maintains the height of the upper end unchanged.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] 1. When the present invention is used for plastic crushing and recycling, the plastic is slowly transferred to the storage barrel through the conveyor belt, and the plastic that falls into the storage barrel gathers toward the center and is concentrated in the ball holder. The bidirectional screw is driven to drive the lifting column to move upward until the ball holder moves to the top of the drainage tube, and the arc-shaped teeth on the outer surface of the ball holder are meshed with the gear. At this time, the gear is driven to rotate, driving the ball holder to rotate ninety degrees. The plastic will slide along the surface of the wear-resistant soft material into the drainage tube and enter the crushing box for crushing. By loading the plastic in this way, not only can the quantitative loading of the plastic be achieved, but also the width of the lifting column is consistent from top to bottom, and there will be no jamming during the loading process, thereby ensuring the smoothness of the loading.

[0018] 2. When the plastic in the ball holder of the present invention pours into the side groove, due to the effect of the wear-resistant soft material, no plastic residue will remain between the ball holder and the side groove.

[0019] 3. In the present invention, when the lifting column moves upward to the point where the gear meshes with the arc-shaped teeth on the outer wall of the upper end of the ball holder, the conductive ring and the conductive strip are in sliding contact. At this time, the conductive arc, the conductive ring, the conductive strip and the first magnetic block electrically connected to the external power supply form a complete circuit. The external power supply supplies power to the first magnetic block. After being energized, the first magnetic block has magnetism and can attract the second magnetic block to move upward. The first spring is compressed, and the second magnetic block detaches from the lower groove and shrinks in the lower groove. At this time, the rotation of the gear can drive the ball holder to rotate, thereby unloading the plastic in the ball holder.

[0020] 4. The intersection of the two thread grooves of the bidirectional thread groove of the present invention is connected with the end groove. When the slider moves to this position, the limit block just passes through the limit groove from below to above the limit ring. At this time, the slider just moves into the end groove and slides with the end groove limit. Under the limiting action of the limit ring, the limit block will not fall downward. After the bidirectional screw rotates one circle, the limit block returns to the position of the limit groove. Under the action of gravity, the limit block passes through the limit groove and falls downward. At this time, the slider also slides from the end groove to the thread groove in the other direction of the bidirectional thread groove, realizing the smooth downward movement of the lifting column. When the slider rotates one circle in the end groove, the lifting column maintains the height of the uppermost end unchanged. This process is used for the gear to drive the ball support to unload.

[0042] like Figure 1-Figure 10As shown, the inner wall of the lower end of the lifting column 414 is provided with a limiting ring 151 sleeved on the outside of the bidirectional screw rod 141, a limiting block 152 is provided on one side of the upper end of the bidirectional screw rod 141, and a limiting groove 153 for passing through the limiting block 152 is provided on the limiting ring 151, and an end groove 154 connected to the bidirectional thread groove 143 is provided on the upper end of the bidirectional screw rod 141.

When the slider 144 moves to this position, the limiting block 152 just passes through the limiting groove 153 from below to the top of the limiting ring 151. At this time, the slider 144 just moves The lifting column 414 moves to the end groove 154 and slides with the end groove 154 in a limited position. Under the limiting action of the limiting ring 151, the limiting block 152 will not fall downward. After the two-way screw rod 141 rotates one circle, the limiting block 152 returns to the position of the limiting groove 153. Under the action of gravity, the limiting block 152 passes through the limiting groove 153 and falls downward.

When it moves to the uppermost position, the slider 144 pushes open the flap 172, driving the flap 172 to rotate and be placed on one end of the end slot 154. The slider 144 slides into the end slot 154 along the flap 172 and slides for one circle. When the slider 144 is separated from the flap 172, the second spring 173 pulls the flap 172 to return to its original position. When the slider 144 slides out of the end slot 154, it directly slides into the reverse thread groove 162 from above the flap 172. At this time, the rotation of the bidirectional screw rod 141 drives the lifting column 414 to move downward.

[0044] Working principle: When plastic is crushed and recycled, the plastic is slowly transferred to the storage barrel 413 through the conveyor belt 411. In the initial state, the lifting column 414 is located inside the base 415, leaving only the ball holder 512 exposed outside, and the edge of the ball holder 512 is flush with the top of the base 415. The plastic that falls into the storage barrel 413 gathers toward the center and is concentrated in the ball holder 512. The bidirectional screw rod 141 drives the lifting column 414 to move upward until the ball holder 512 moves to the top of the drainage tube 7, and the arc-shaped teeth 612 on the outer surface of the ball holder 512 mesh with the gear 611. At this time, the gear 611 is driven to rotate. The drive rotates, causing the ball holder 512 to rotate ninety degrees, and the plastic in the ball holder 512 is poured into the side groove 511. Under the action of the wear-resistant soft material 8, no plastic residue will be left between the ball holder 512 and the side groove 511. The plastic will slide along the surface of the wear-resistant soft material 8 into the drainage tube 7, and move to the crushing box 1 through the drainage tube 7 for crushing. The crushed plastic is finally discharged from the discharge pipe 3. By loading the plastic in this way, not only can the quantitative loading of the plastic be achieved, but also the width of the lifting column 414 is consistent from top to bottom, and there will be no jamming during the loading process, thereby ensuring the smoothness of the loading.
