Description

Technical Field

[0001] This utility model relates to the field of waste paperboard recycling technology, and in particular to a waste cardboard box collection device. Background Technology

[0002] Cardboard boxes, as the most widely used packaging product, come in various types depending on the materials used, such as corrugated cardboard boxes and single-layer cardboard boxes, and come in a wide variety of specifications. During the production process, cardboard often requires cutting operations such as slotting and corner trimming, which inevitably generates a large amount of waste cardboard. With the continuous expansion of cardboard box production scale and the increasing awareness of environmental protection, the effective collection and treatment of cardboard box waste has become increasingly crucial.

[0003] Currently, existing waste collection devices for cardboard box production have some problems during use. The crushing mechanism used in some devices does not crush the waste cardboard evenly, resulting in poor crushing effect. It cannot screen the crushed waste cardboard fragments, causing larger pieces of waste cardboard to be mixed in, which increases the difficulty of subsequent collection and processing. Therefore, it is of great practical significance to develop an efficient, convenient cardboard box waste collection device with good crushing effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste cardboard box collection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste cardboard collection device includes a crushing box. A rotating rod is rotatably connected between the two ends of the inner wall of the crushing box. A fixed roller is fixedly fitted onto the circumferential surface of the rotating rod, and multiple cutters are fixedly connected to the outer circumferential wall of the fixed roller. A screening mechanism is provided inside the crushing box at the bottom of the rotating rod. The screening mechanism includes four pairs of fixed blocks fixedly connected to the four corners of the inner wall of the crushing box. A sliding rod is fixedly connected between each pair of fixed blocks. A curved plate is slidably fitted onto the circumferential surface of the four sliding rods, and the curved plate is adapted to the cutters. Multiple sieve holes are evenly spaced in the middle of the curved plate. Vertical plates are fixedly connected to the middle of both sides of the bottom of the curved plate. Slanted holes are provided on both vertical plates. The reciprocating lifting and lowering of the curved plate facilitates the throwing of waste cardboard from the top, making it easier for it to contact the cutters.

[0007] Preferably, square sleeve blocks are fixedly embedded at both ends of the middle part of one side of the outer wall of the crushing box. The crushing box has square holes that are adapted to the two square sleeve blocks. Telescopic rods are slidably fitted on the inner walls of the two square sleeve blocks. One end of the two telescopic rods located inside the crushing box is fixedly connected to a protruding rod, and each protruding rod is slidably connected in a close oblique hole. The outer ends of the two telescopic rods are fixedly connected to the same connecting rod.

[0008] Preferably, a mounting frame is fixedly connected to the outer wall of the crushing box near the square sleeve block. A drive rod is rotatably connected to the inner side of the mounting frame near the connecting rod. A large gear and a cylinder are fixedly mounted on the drive rod. An annular groove is formed on the circumferential surface of the cylinder. A sliding rod is slidably connected to the bottom of the annular groove. The sliding rod is fixedly connected to the middle position of the top of the connecting rod. By rotating the cylinder, in conjunction with the annular groove and the sliding rod, the telescopic rod reciprocates, thereby enabling the convex rod to drive the screening mechanism to operate.

[0009] Preferably, a motor is fixedly connected to the outer side of the mounting bracket near the top, and a small gear is fixedly connected to the output end of the motor through the mounting bracket, and the small gear meshes with the large gear.

[0010] Preferably, the motor output end also passes through the crushing box and is fixedly connected to one end of the rotating rod via a coupling.

[0011] Preferably, the top of the crushing box is provided with a feeding hopper, and a slot is provided on one side of the bottom of the crushing box, and a collection box is provided in the slot.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing technologies such as a screening mechanism, telescopic rods, connecting rods, protruding rods, cylinders, large gears, and annular inclined grooves, the rotation of the motor causes the cutter to rotate and pulverize the waste paperboard. Simultaneously, the two telescopic rods reciprocate, driving the screening mechanism to move the arc-shaped plate up and down. This allows waste paperboard that cannot pass through the screen holes to be cut and pulverized again until it meets the required standards. This effectively solves the problem of poor pulverization effect mentioned in the background technology, thereby achieving a finer and more uniform pulverization effect for waste paperboard. It ensures that the particle size of the waste material meets the recycling standards, reduces subsequent processing costs, and provides technical support for the efficient recycling of cardboard waste.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A waste cardboard box collection device includes a crushing box 1. A rotating rod 3 is rotatably connected between the two ends of the inner wall of the crushing box 1. A fixed roller 301 is fixedly sleeved on the circumference of the rotating rod 3, and multiple cutters 302 are fixedly connected to the outer circumference of the fixed roller 301. A screening mechanism 4 is provided inside the crushing box 1 at the bottom of the rotating rod 3. The screening mechanism 4 includes four pairs of fixed blocks 401 fixedly connected to the four corners of the inner wall of the crushing box 1. Each pair of fixed blocks 401 is fixedly connected to a single... The slide bar 402 has four slide bars 402 with the same arc plate 403 slidingly mounted on their circumferential surfaces. The arc plate 403 is adapted to the cutter 302. Multiple sieve holes 404 are evenly spaced in the middle of the arc plate 403. Vertical plates 405 are fixedly connected to the middle of the bottom two sides of the arc plate 403. Slanted holes 406 are opened on both vertical plates 405. When the arc plate 403 rises to the highest point, the gap between the cutter 302 and the arc of the arc plate 403 will be very small, which makes it easy to cut the waste cardboard at the top of the arc plate 403.

[0021] In this utility model, square sleeve blocks 5 are fixedly embedded at both ends of the middle part of one side of the outer wall of the crushing box 1. The crushing box 1 has square holes that are adapted to the two square sleeve blocks 5. The inner walls of the two square sleeve blocks 5 are slidably fitted with telescopic rods 501. One end of the two telescopic rods 501 located inside the crushing box 1 is fixedly connected with a protruding rod 503, and each protruding rod 503 is slidably connected in a close inclined hole 406. The outer ends of the two telescopic rods 501 are fixedly connected with the same connecting rod 502.

[0022] In this utility model, a mounting bracket 2 is fixedly connected to the outer wall of the crushing box 1 near the square sleeve block 5. A drive rod 203 is rotatably connected to the inner side of the mounting bracket 2 near the connecting rod 502. A large gear 205 and a cylinder 204 are fixedly mounted on the drive rod 203. An annular groove 206 is formed on the circumferential surface of the cylinder 204. A sliding rod is slidably connected to the bottom of the annular groove 206. The sliding rod is fixedly connected to the middle position of the top of the connecting rod 502. By rotating the cylinder 204, the sliding rod causes the connecting rod 502 and the telescopic rod 501 to reciprocate and extend.

[0023] In this utility model, a motor 201 is fixedly connected to the outer side of the mounting bracket 2 near the top. A small gear 202 is fixedly connected to the output end of the motor 201 through the mounting bracket 2. The small gear 202 meshes with a large gear 205. The arrangement of the small gear 202 and the large gear 205 facilitates the reduction of the rotation of the motor 201.

[0024] In this utility model, the output end of the motor 201 also passes through the crushing box 1 and is fixedly connected to one end of the rotating rod 3 via a coupling.

[0025] In this utility model, a feed hopper 102 is provided on the top of the crushing box 1, and a slot is provided on one side of the bottom of the crushing box 1, and a collection box 101 is provided in the slot. The collection box 101 is provided to facilitate the collection of shredded waste cardboard.

[0026] Working principle: When using this device, the motor 201 is connected to the mains power. Waste paper from cardboard box production is fed into the feed hopper 102 via a conveyor belt, and then enters the crushing box 1. The motor 201 is turned on, and the rotating rod 3 and the cutter 302 cut the waste cardboard entering the crushing box 1. The cut waste paper falls onto the arc plate 403 of the screening mechanism 4. Smaller pieces of waste paper enter the collection box 101 through the screen holes 404, while larger pieces of waste cardboard do not fall and remain on the top of the arc plate 403. At the same time, the motor 201, through the small gear 202 and the large gear 205, causes the drive rod 203 to drive the cylindrical 2 04 rotates, and at the same time, the rotation of cylinder 204 decreases. Through the cooperation of sliding rod and annular inclined groove 206, the two telescopic rods 501 extend and retract back and forth. With the cooperation of protruding rod 503 and inclined hole 406, the arc plate 403 moves up and down along sliding rod 402, which throws the waste cardboard at the top of the arc plate 403 up, making it easier to cut it again with cutter 302. At the same time, the arc plate 403 and cutter 302 are matched. When the arc plate 403 rises to the highest point, cutter 302 will approach the arc of the arc plate 403, making it easier to cut the waste cardboard at the arc of the arc plate 403 until qualified waste cardboard falls from the screen hole 404.
