Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a plastic pallet crushing device based on comprehensive utilization of solid wastes for environmental protection. Background Art

[0002] Plastic pallets are a type of logistics equipment used for the storage, transportation and handling of goods. Plastic pallets are made of plastic as the main raw material through injection molding, blow molding and other processes. They are mainly used for the collection, stacking, handling and transportation of goods. They are widely used in many industries such as food, beverages, medicine, chemicals, and electronics. They can be used in conjunction with logistics equipment such as forklifts and stackers to achieve mechanized handling and storage of goods, improve logistics efficiency, and reduce labor intensity.

[0003] Since plastic pallets are made of plastic, from the perspective of environmental protection and resource recycling, damaged and discarded plastic pallets or defective products in the production process of plastic pallets will be cut into pieces by crushing equipment for recycling.

[0004] A plastic pallet crushing device is disclosed in the patent publication number CN221339112U, which is convenient for more thorough crushing of plastic pallets, has high efficiency and strong practicality, and includes a crushing box, a feed hopper, a rotating shaft, a relatively rotating component, a filter, a cleaning component, a lifting plate, a lifting component, a pushing component and a feed plate. The feed hopper is connected to the crushing box, two rotating shafts are provided, the rotating shafts are rotatably connected to the crushing box, a plurality of crushing knives are fixedly connected to the rotating shaft, the relatively rotating component is provided on the two rotating shafts, and is used to drive the two rotating shafts to rotate relative to each other, the filter is fixedly connected to the crushing box, the cleaning component is provided on the crushing box, and is used to clean the plastic blocks filtered out by the filter, and a cleaning port is provided on the crushing box, the lifting plate is slidably connected to the crushing box, a collecting drawer is fixedly connected to the lifting plate, and the lifting component is provided on the crushing box, and is used to drive the lifting plate to move up and down.

[0005] The prior art has the following defects:

[0006] Plastic pallets are relatively hard and brittle, especially after aging, the brittle nature of the material will become more prominent. During crushing, if the tool is not sharp enough due to wear, the plastic pallet will be subjected to stress and crack. At the moment of cracking, the internal stress of the material is released, causing the plastic pallet body and the cracked fragments to bounce and splash. This will not only affect the crushing efficiency, but the plastic pallet may also damage the tool by colliding with the tool after bouncing. If the plastic pallet body and the cracked fragments bounce and splash out from the feeding port of the crushing equipment, it will also endanger the safety of the operator. Summary of the invention

[0007] In view of the problem in the prior art that the main body of the plastic pallet and the broken fragments bounce and splash when crushed, a plastic pallet crushing device based on comprehensive utilization of solid waste for environmental protection is proposed.

[0008] The present application provides a plastic pallet crushing device based on comprehensive utilization of solid waste for environmental protection, the purpose of which is to avoid bouncing and splashing of the plastic pallet body and the crushed fragments.

[0009] The technical solution of the present invention is: a plastic pallet crushing device based on comprehensive utilization of solid waste for environmental protection, used for processing discarded plastic pallets, including a stand, a crusher arranged above the stand, the crusher is divided into a feeding area and a crushing area, a crushing wheel is arranged inside the crushing area, and also includes an auxiliary feeding component arranged outside the crusher, the auxiliary feeding component specifically includes an installation box arranged above the opening of the feeding area, and a pressure plate is rotatably connected in the installation box;

[0010] The pressing plate is tiltedly arranged in the feeding area and divides the inner space of the feeding area into two parts. When the plastic pallet is put in, the pressing plate is pushed upward to form a sliding opening.

[0011] Furthermore, a bending angle of not less than one hundred and twenty degrees is provided at the connection between the feeding zone and the crushing zone.

[0012] Furthermore, the pressing plate specifically includes a plate body, a cavity opened on the upper surface of the plate body, and a cover plate arranged at the opening of the cavity.

[0013] Furthermore, the auxiliary feeding assembly also includes an inner liner arranged between the mounting box and the pressing plate, a rotating groove provided on the lower surface of the pressing plate, a rotating wheel provided inside the rotating groove, a trigger plate and an adjusting rod provided outside the rotating wheel, a socket provided on one end of the plate body close to the mounting box, an insertion rod provided inside the insertion groove, a reset spring provided between the insertion rod and the inner wall of the insertion groove, a connecting rope provided between the insertion rod and the adjusting rod, a mounting groove provided on the inner side of the inner liner, a positioning plate provided inside the mounting groove, a positioning groove provided on the surface of one side of the positioning plate close to the plate body, a fixing groove provided on the outer side of the inner liner, a connecting groove provided between the fixing groove and the mounting groove, a connecting rod provided on one side of the positioning plate close to the buffer spring, and a fixing platform provided inside the fixing groove;

[0014] The rotating groove extends to the lower surface of the plate body and the inner wall of the cavity, the trigger plate is located on the outside of the plate body, the adjusting rod is located inside the cavity, the insertion rod extends into the cavity, the connecting rod extends into the fixing groove and is fixed to the fixing platform through bolts, and the positioning grooves are distributed in a circular array along the surface contour of the positioning plate.

[0015] Furthermore, the length of the installation slot is greater than the length of the positioning plate, the length of the connecting slot is greater than the length of the connecting rod, the length of the fixing slot is greater than the length of the fixing platform, and buffer springs are provided at both ends of the fixing platform.

[0016] Furthermore, the bottom of the board body and the inner wall of the cavity are both provided with storage grooves, which extend into the rotating groove. The storage groove on the surface of the board body is located on the side of the rotating groove away from the installation box, and the storage groove on the inner wall of the cavity is located on the side of the rotating groove close to the installation box.

[0017] Furthermore, the weight of the adjusting rod is greater than that of the trigger plate, and under the action of gravity, the adjusting rod is driven downward with the rotating wheel as a fulcrum, and the trigger plate is lifted up.

[0018] Furthermore, the trigger plate is limited by the opening angle of the rotating slot and is deflected upward to the maximum extent to remain perpendicular to the bottom wall of the feeding area.

[0019] Furthermore, the trigger plate is limited by the opening angle of the rotation slot and is deflected upward to the maximum extent to remain perpendicular to the bottom wall of the plate body.

[0020] Furthermore, a row of hanging curtains is arranged in the middle of the lower surface of the pressing plate, and the hanging curtains are composed of plastic ribbons arranged linearly.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting a pressure plate, when the plastic pallet is put in, the plastic pallet pushes the pressure plate upward to form a downward slide. The plastic pallet enters the crushing area from the downward slide, and the pressure plate is pressed on the top of the plastic pallet. In this way, the pressure plate restricts the plastic pallet and avoids the plastic pallet from moving too much. It plays a certain stabilizing role, improves the crushing efficiency, and extends the service life of the tool. At the same time, the cracked fragments splash upward to the top of the pressure plate and are blocked by the pressure plate, thus ensuring the processing safety.

[0023] 2. By setting up the auxiliary feeding assembly, when the plastic pallet is put in, the pressing plate is pushed upward and rotates inside the liner. When the plastic pallet partially passes through the lower slide opening and is about to enter the crushing area, the trigger plate is pushed downward by the plastic pallet and deflected. The connecting rope loosens the plug rod to insert it into the positioning groove, locking the pressing plate and the plate body together. In this way, the pressing plate is fixed, which has a better restraining effect on the plastic pallet.

[0024] 3. By setting a buffer spring, the positioning plate has a certain amount of space for movement in the installation groove. In this way, while ensuring that the pressure plate has sufficient binding force on the plastic pallet, it can avoid the pressure plate from generating excessive resistance to the downward movement of the plastic pallet.

[0025] 4. By setting the deflection angle of the limiting trigger plate, when the force direction of the plastic pallet is parallel to the bottom surface of the feeding area, the plastic pallet moves upward along the lower slide. During this process, the trigger plate will rotate upward and get stuck in the gap on the surface of the plastic pallet, making it impossible for the plastic pallet to move upward, further limiting the plastic pallet.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] Example 1, reference Figure 1-13 , which is the first embodiment of the present invention, provides a plastic pallet crushing equipment based on comprehensive utilization of solid waste for environmental protection, which is used to process discarded plastic pallets, including a stand 1, a crusher 2 arranged above the stand 1, the crusher 2 is divided into a feeding area 21 and a crushing area 22, a crushing wheel 23 is arranged inside the crushing area 22, and also includes an auxiliary feeding component 3 arranged on the outside of the crusher 2, the auxiliary feeding component 3 specifically includes an installation box 31 arranged above the opening of the feeding area 21, and a pressure plate 32 is rotatably connected inside the installation box 31.

[0044] Specifically, the stand 1 is arranged in a two-layer stepped shape, the crusher 2 is welded to the top of the second layer of the stand 1 step, and the energy-saving motor is fixedly installed on the top of the first layer of the stand 1 step by bolts. The energy-saving motor is connected to the crushing wheel 23 through a transmission belt. By using the energy-saving motor, the overall power consumption of the equipment is reduced. The transmission belt is made of polyurethane, which has the characteristics of high strength, good wear resistance and high transmission efficiency. This also reduces the operating power consumption of the equipment to a certain extent. The installation box 31 is fixed to the feeding area 21 by bolts, and the pressure plate 32 is tilted in the feeding area 21 and divides the internal space of the feeding area 21 into two. When the plastic pallet is put in, the pressure plate 32 is pushed upward to form a downward slide. The pressure plate 32 is made of aluminum alloy material. The connection between the feeding area 21 and the crushing area 22 is provided with a bending angle of not less than one hundred and two degrees, that is, the crushing area 22 is vertically arranged, and the feeding area 21 is tilted above the crushing area 22. The downward slide is located on the side of the crushing area 22, reducing the probability of the cracked fragments splashing into the downward slide.

[0045] By setting the pressing plate 32, when the plastic pallet is put in, the plastic pallet pushes the pressing plate 32 upward to form a sliding groove, and the plastic pallet enters the crushing area 22 from the sliding groove. The pressing plate 32 is pressed on the top of the plastic pallet, so that the pressing plate 32 has a limiting effect on the plastic pallet, which can prevent the plastic pallet from moving too much, plays a certain stabilizing role, improves the crushing efficiency, and extends the service life of the tool. At the same time, the cracked fragments splash upward to the top of the pressing plate 32 and are blocked by the pressing plate 32, thereby ensuring processing safety.

[0046] Specifically, the pressing plate 32 includes a plate body 321, a cavity 322 opened on the upper surface of the plate body 321, and a cover plate 323 arranged at the opening of the cavity 322. The hollow design reduces the overall weight of the pressing plate 32 so that it does not affect the sliding of the plastic pallet.

[0047] The auxiliary feeding assembly 3 also includes an inner lining 320 disposed between the mounting box 31 and the pressing plate 32, a rotating groove 33 provided on the lower surface of the pressing plate 32, a rotating wheel 34 provided inside the rotating groove 33, a trigger plate 35 and an adjusting rod 36 provided outside the rotating wheel 34, a socket 37 provided on one end of the plate body 321 close to the mounting box 31, a plug rod 38 provided inside the plug rod 37, a return spring 39 provided between the plug rod 38 and the inner wall of the plug rod 37, and a spring 39 provided between the plug rod 38 and the adjusting rod 36. A connecting rope 310 is provided in between, a mounting groove 311 is provided on the inner side of the lining 320, a positioning plate 312 is arranged inside the mounting groove 311, a positioning groove 313 is provided on the surface of the positioning plate 312 on the side close to the plate body 321, a fixing groove 315 is provided on the outer side of the lining 320, a connecting groove 314 is provided between the fixing groove 315 and the mounting groove 311, a connecting rod 316 is provided on the side of the positioning plate 312 close to the buffer spring 318, and a fixing platform 317 is provided inside the fixing groove 315.

[0048] Specifically, the connection between the board body 321 and the installation box 31 is set to be in an arc shape, the rotating groove 33 extends to the lower surface of the board body 321 and the inner wall of the cavity 322, the rotating wheel 34 is rotatably connected to the rotating groove 33, the main part of the rotating groove 33 is cylindrical, and the opening width on both sides of the rotating groove 33 is smaller than the diameter of the rotating groove 33, the trigger plate 35 is located on the outside of the board body 321, the adjustment rod 36 is located inside the cavity 322, the insertion rod 38 extends into the cavity 322, and a C-shaped wire clip is fixedly connected to the inner wall of the board body 321. The connecting rope 310 slides through the wire clip, and the insertion rod 38 can be inserted into the positioning groove 313. The installation groove 311 is arc-shaped, the positioning plate 312 is attached to the outer wall of the board body 321, the connecting rod 316 extends into the fixing groove 315, and is bolted in the fixing platform 317, the positioning grooves 313 are distributed in a ring array along the surface contour of the positioning plate 312, and the fixing platform 317 is slidably installed in the fixing groove 315.

[0049] By setting the auxiliary feeding assembly 3, when the plastic pallet is put in, the pressing plate 32 is pushed upward, and the pressing plate 32 rotates inside the lining 320. When the plastic pallet partially passes through the lower sliding opening and is about to enter the crushing area 22, the trigger plate 35 is pushed downward by the plastic pallet to deflect, and the connecting rope 310 loosens the insertion rod 38 to insert it into the positioning groove 313, locking the pressing plate 32 and the plate body 321 together, so that the pressing plate 32 is fixed, and the binding effect on the plastic pallet is better.

[0050] Specifically, the length of the mounting groove 311 is greater than the length of the positioning plate 312, the length of the connecting groove 314 is greater than the length of the connecting rod 316, the length of the fixing groove 315 is greater than the length of the fixing platform 317, and buffer springs 318 are provided at both ends of the fixing platform 317. The two ends of the fixing platform 317 are provided with restraining grooves, and the buffer springs 318 are fixed in the restraining grooves.

[0051] By providing the buffer spring 318 , the positioning plate 312 has a certain movable space in the installation slot 311 , so as to ensure that the pressing plate 32 has sufficient binding force on the plastic pallet and avoid the pressing plate 32 from generating excessive resistance to the downward movement of the plastic pallet.

[0052] Specifically, a storage groove 319 is provided at the bottom of the plate body 321 and the inner wall of the cavity 322. The storage groove 319 extends into the rotating groove 33. The storage groove 319 on the surface of the plate body 321 is located on the side of the rotating groove 33 away from the installation box 31, and the storage groove 319 on the inner wall of the cavity 322 is located on the side of the rotating groove 33 close to the installation box 31. Both the trigger plate 35 and the adjustment rod 36 can be received in the storage groove 319.

[0053] Specifically, the weight of the adjusting rod 36 is greater than that of the trigger plate 35. Under the action of gravity, the adjusting rod 36 is driven downward with the rotating wheel 34 as a fulcrum, and the trigger plate 35 is lifted. When the adjusting rod 36 moves downward, the insertion rod 38 is pulled by the connecting rope 310 to compress the reset spring 39, so that the device has an automatic reset function. The pulling force of the adjusting rod 36 on the insertion rod 38 through the connecting rope 310 is greater than the force required for the compression of the reset spring 39.

[0054] A row of hanging curtains is set in the middle of the lower surface of the pressing plate 32. The hanging curtains are composed of plastic ribbons arranged linearly. When not affected by external forces, the hanging curtains are always perpendicular to the ground, so as to shield the sliding opening and prevent the plastic pallet from being much smaller than the feeding opening of the feeding area 21. When the opening, the opening area is too large, causing plastic fragments to splash out from the sliding opening.

[0055] Example 2, reference Fig.13 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the trigger plate 35 is limited by the opening angle of the rotating groove 33, and is deflected upward to the maximum to remain perpendicular to the bottom wall of the feeding area 21, so that the placement state of the pressing plate 32 is more stable.

[0056] By setting the deflection angle of the limiting trigger plate 35, when the force direction of the plastic pallet is parallel to the bottom surface of the feeding area 21, the plastic pallet moves upward along the lower sliding opening. During this process, the trigger plate 35 will rotate upward and get stuck in the gap on the surface of the plastic pallet, so that the plastic pallet can no longer move upward, thereby further limiting the plastic pallet.

[0057] Example 3, reference Fig.14 , which is the third embodiment of the present invention. This embodiment is different from the first embodiment in that: the trigger plate 35 is limited by the opening angle of the rotating groove 33, and is deflected upward to the maximum to remain perpendicular to the bottom wall of the plate body 321. This makes it easier to push the trigger plate 35 when the plastic tray slides down, avoiding jamming.

[0058] The working principle of the plastic pallet crushing equipment based on comprehensive utilization of solid waste for environmental protection is as follows:

[0059] During installation, lubricating oil is applied to the outside of the rotating wheel 34 and it is squeezed into the rotating groove 33. During this process, the adjusting rod 36 is kept inserted into the cavity 322. Then the reset spring 39 is sleeved on the outside of the insertion rod 38, and then both are inserted into the socket 37 together. One end of the socket 37 passes through the cavity 322. Finally, the insertion rod 38 and the adjusting rod 36 are connected by the connecting rope 310, and the connecting rope 310 is tightened.

[0060] Insert the positioning plate 312 into the installation groove 311, make the connecting rod 316 pass through the connecting groove 314 and enter the fixing groove 315, then fix the buffer spring 318 on both sides of the fixing platform 317, and then insert the fixing platform 317 into the fixing groove 315 and fix it to the connecting rod 316 with bolts; place the lining 320 into the inner side of the installation box 31, fix it with bolts, and then install the pressing plate 32 on the inner side of the lining 320, and finally fix the installation box 31 above the opening of the feeding area 21, so that the pressing plate 32 is inserted into the feeding area 21.

[0061] When in use, under the action of gravity, the pressing plate 32 is deflected downward and tilted to be placed in the feeding area 21. After the plastic pallet is put in, the plastic pallet slides down along the bottom wall of the feeding area 21. When the put in plastic contacts the pressing plate 32, the pressing plate 32 is pushed upward, and a sliding opening is formed between the pressing plate 32 and the bottom wall of the feeding area 21. The put in plastic enters the sliding opening. When the put in plastic is about to slide out of the sliding opening, the put in plastic contacts the trigger plate 35, and the trigger plate 35 is pushed downward. The trigger plate 35 deflects downward and drives the adjusting rod 36 to deflect upward through the rotating wheel 34. The connecting rope 310 becomes loose, and the reset spring 39 pushes the insertion rod 38 toward the lining 320. The insertion rod 38 is inserted into the positioning groove 313, so that the size of the sliding opening below the pressing plate 32 is fixed.

[0062] The plastic pallet enters the crushing area 22 through the lower sliding opening and is shredded by the crushing wheel 23. When the plastic pallet exerts too much force on the pressure plate 32, the pressure plate 32 can still be offset upward by a certain distance. The pressure plate 32 is offset upward, and the positioning plate 312 is driven to be offset through the insertion rod 38. The positioning plate 312 drives the fixed platform 317 to be offset through the connecting rod 316 and compresses the buffer spring 318. Then the buffer spring 318 pushes the fixed platform 317 and the pressure plate 32 to reset.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
