Technical Field

[0001] This utility model relates to the technical field of packaging waste treatment equipment, specifically a packaging cardboard box crushing device. Background Technology

[0002] In the current packaging industry, cardboard boxes are widely used for packaging various commodities due to their low cost and easy biodegradability. The large amount of waste cardboard boxes generated, if discarded directly without effective treatment, not only wastes wood resources but also increases the processing load on landfills or incinerators. Existing cardboard box shredding devices have many limitations in practical applications: on the one hand, waste cardboard boxes are often bulky and large, easily causing jamming when directly entering the shredding mechanism, and the low utilization rate of the shredding chamber space leads to low shredding efficiency; on the other hand, the shredded cardboard box fragments are loose and occupy a large amount of space, causing inconvenience for subsequent collection, transportation, and pre-treatment before recycling, increasing recycling costs. Therefore, there is an urgent need for a device that can achieve integrated processing of cardboard box flattening, shredding, and compaction to improve the efficiency and convenience of recycling waste packaging cardboard boxes. Utility Model Content

[0015] Please see Figure 1 - Figure 5 A packaging paper box crushing device includes a crushing box 1, a flattening component, a crushing component and a compacting component. The top of the crushing box 1 is provided with a feeding port 3, and the flattening component is provided below the feeding port 3 inside the crushing box 1. The flattening assembly includes a bidirectional lead screw 6, a first motor 603, and a pressing plate 604. Support plates 602 are provided on both sides of the rear side wall of the crushing box 1. The first motor 603 is provided on the support plate 602. The end of the first motor 603 near the crushing box 1 is rotatably connected to one end of the bidirectional lead screw 6. The other end of the bidirectional lead screw 6 is rotatably connected to the inner wall of the crushing box 1 on the side away from the support plate 602. Limiting blocks 601 are movably connected to the middle of the support plate 602. The side of the limiting blocks 601 that is away from each other is fixedly connected to the inner wall of the crushing box 1. The two ends of the bidirectional lead screw 6 inside the crushing box 1 are threadedly connected to the middle of one side of the two pressing plates 604 respectively. A crushing assembly is provided below the bidirectional lead screw 6.

[0016] Through the above technical solution, a feeding port 3 is set at the top of the crushing box 1 for feeding packaging cartons. A flattening assembly consisting of a bidirectional lead screw 6, a first motor 603, a pressing plate 604, a support plate 602, and a limiting block 601 is set below the feeding port 3. The first motor 603 drives the bidirectional lead screw 6 to rotate, causing the two pressing plates 604 to move closer or further apart along the bidirectional lead screw 6. With the limiting block 601 limiting and guiding the support plate 602, the fed packaging cartons are quickly flattened, and the fluffy cartons are pressed into sheets. This provides pretreatment for the efficient operation of the subsequent crushing assembly and avoids the problem of material jamming caused by the large volume of the cartons.

[0017] This utility model provides a technical solution in which the crushing component includes a drive gear 8, a first transmission rod 801, a second motor 803, a driven gear 9, and a second transmission rod 901; A support frame 802 is provided on the right side wall of the crushing box 1. A second motor 803 is provided on the support frame 802. The side of the second motor 803 away from the support frame 802 is rotatably connected to one end of the first transmission rod 801. The other end of the first transmission rod 801 is rotatably connected to the inner wall of the left side of the crushing box 1. A drive gear 8 is fixedly connected between the right side wall of the first transmission rod 801 and the second motor 803. A first crushing roller 804 is fixedly connected to the periphery of the first transmission rod 801 inside the crushing box 1. A driven gear 9 meshes with the rear side of the drive gear 8. The middle part of the driven gear 9 is fixedly connected to one end of the second transmission rod 901. The other end of the second transmission rod 901 is rotatably connected to the inner wall of the left side of the crushing box 1. A second crushing roller 902 is fixedly connected to the periphery of the second transmission rod 901 inside the crushing box 1. A first guide plate 7 is disposed between the pressure plate 604 inside the crushing chamber 1 and the first transmission rod 801.

[0018] Through the above technical solution, a support frame 802 is set up to provide stable support for the second motor 803. The second motor 803 drives the first transmission rod 801 to rotate, which in turn drives the first crushing roller 804 to rotate synchronously. At the same time, the driving gear 8 and the driven gear 9 on the first transmission rod 801 mesh and drive the second transmission rod 901 and the second crushing roller 902 to rotate in opposite directions, so that the first crushing roller 804 and the second crushing roller 902 form a counter-shearing motion, thereby achieving efficient crushing of the flattened cardboard box. The first guide plate 7 set in the crushing box 1 can accurately guide the flattened cardboard box by the pressing plate 604 to the two crushing rollers, avoiding cardboard box deviation or jamming, and further improving the stability and continuity of the crushing process.

[0019] This utility model provides a technical solution. The compaction component includes a hydraulic piston cylinder 11 and a compression plate 12. A compression box 4 is provided at the bottom of the crushing box 1. Multiple hydraulic piston cylinders 11 are provided on the inner walls of the front and rear sides of the compression box 4. The side of the hydraulic piston cylinder 11 closest to the crushing box 1 is fixedly connected to one end of the piston rod 1101, and the other end of the piston rod 1101 is fixedly connected to one side of the compression plate 12. A second guide plate 10 is disposed between the compression plate 12 and the first transmission rod 801 inside the crushing box 1; A drawer 5 is provided on the side of the compression box 4 away from the support frame 802. The drawer 5 has an "L" shaped structure. A handle 501 is provided on the side wall of the drawer 5 away from the compression box 4. Multiple dovetail protrusions 502 are provided at the bottom of the drawer 5. Multiple dovetail grooves 401 are provided on the bottom of the inner wall of the compression box 4 corresponding to the dovetail protrusions 502.

[0020] Through the above technical solution, the compression box 4 at the bottom of the crushing box 1 provides a closed space for the compaction operation. Multiple hydraulic piston cylinders 11 set on the inner walls of its front and rear sides drive the compression plates 12 to move in opposite directions through the piston rods 1101, so as to achieve strong compaction of the crushed paper box debris and greatly reduce the volume of debris. The second guide plate 10 inside the crushing box 1 can accurately guide the debris processed by the crushing components into the compression box 4, so as to avoid debris remaining on the box wall. The "L"-shaped drawer 5 on the side of the compression box 4 cooperates with the dovetail protrusion 502 at the bottom and the dovetail groove 401 at the bottom of the inner wall of the compression box 4 to achieve stable pull-out. Its unique structure only forms a support between the side with the handle 501 and the bottom, and forms a closed space with the inner wall of the compression box. This not only facilitates the compaction of debris by the compression plate 12, but also facilitates the overall removal of the compacted debris, further improving the ease of operation of the device.

[0021] The working principle of this utility model is as follows: During operation, the packaging boxes to be processed are fed into the feeding port 3 at the top of the crushing chamber 1. The boxes are guided by the first guide plate 7 and fall into the flattening assembly area. The first motor 603 starts and drives the bidirectional lead screw 6 to rotate, causing the two pressing plates 604 to move towards each other along the bidirectional lead screw 6. With the guidance of the limiting block 601, the loose boxes are squeezed into sheets for subsequent crushing. The flattened boxes fall into the crushing assembly through the gap between the first guide plates 7. The second motor 803 drives the first transmission rod 801 to rotate, causing the first crushing roller 804 to rotate synchronously. At the same time, the active roller on the first transmission rod 801... Gear 8 meshes with driven gear 9, driving the second transmission rod 901 and the second crushing roller 902 to rotate in opposite directions. The two crushing rollers form a counter-shearing motion, crushing the sheet-like cardboard box into fragments. The crushed fragments are guided by the second guide plate 10 into the "L"-shaped drawer 5 inside the compression chamber 4. The hydraulic piston cylinders 11 on the front and rear sides of the compression chamber 4 push the compression plates 12 to move in opposite directions through the piston rods 1101, compacting the fragments in the drawer 5 to reduce their volume. After compaction, the drawer 5 can be pulled out by the handle 501 along the mating structure of the dovetail protrusion 502 and the dovetail groove 401, and the compacted fragments can be removed. In addition, the maintenance door 2 on the side of the crushing chamber 1 away from the support plate 602 can be opened when the device needs maintenance or malfunctions, facilitating the inspection and replacement of internal flattening and crushing components, ensuring the continuous and stable operation of the device.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
