Technical Field

[0001] This utility model relates to the technical field of plastic bottle crushing devices, specifically a plastic bottle waste crushing device with uniform feeding. Background Technology

[0002] Most old plastic bottles and waste plastics have significant value and can be used to make packaging materials, daily necessities, industrial products, and household goods. To facilitate the subsequent recycling and processing of plastic bottle waste, it is necessary to crush the plastic bottle waste for recycling. However, currently, plastic bottle waste is simply thrown into the crusher all at once, which leads to a large accumulation of plastic bottle waste at the feed inlet, exceeding the effective crushing range of the crusher's blades and significantly affecting the efficiency of the crushing process. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a plastic bottle waste crushing device with uniform feeding.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a uniformly fed plastic bottle waste crushing device, including a crushing box, a feeding hopper fixedly installed on the top of the crushing box, a feed plate fixedly installed at an inclined position on the upper part of the inner wall of the feeding hopper, a movable plate provided on the side of the feeding hopper opposite to the feed plate, a rotating rod rotatably provided at one end of the movable plate near the inner wall of the feeding hopper, both ends of the rotating rod rotatably passing through the feeding hopper, a worm gear fixedly provided at one end of the rotating rod located on the outer wall of the feeding hopper, a worm meshing with the lower part of the worm gear, a drive gear fixedly provided at the end of the worm, and a toothed plate meshing with the drive gear. A vertically mounted cylinder is fixed to the outer wall of the feed hopper near the toothed plate. The output end of the cylinder is coaxially fixed to the toothed plate. Two symmetrically arranged inclined plates are fixed to the bottom of the feed hopper. Two symmetrically arranged drive rollers are rotatably mounted in the crushing box between the two inclined plates. Crushing blades are installed on the drive rollers in a ring. The crushing blades on the two drive rollers are staggered. A fixed plate with an inverted V shape is fixed below the drive rollers in the crushing box. A rotating shaft is rotatably mounted at one end of the fixed plate in the crushing box. The same crushing blades as those mounted on the drive rollers are fixed on the rotating shaft.

[0005] Preferably, the outer wall of the feed hopper is fixedly provided with limiting blocks at the upper and lower ends of the toothed plate, and the upper and lower ends of the toothed plate movably pass through the limiting blocks.

[0006] Preferably, the two drive rollers are connected through one end of the crushing box by two meshing transmission gears. A first motor is fixedly installed on the outer wall of the crushing box near the drive rollers, and the output end of the first motor is coaxially fixedly installed on the drive rollers. The two rotating shafts are connected by belt drive at one end outside the crushing box. A second motor is fixedly installed on the outer wall of the crushing box near one of the rotating shafts, and the output end of the second motor is coaxially fixedly installed on the rotating shaft.

[0007] Preferably, a horizontal plate is fixedly installed above the rotating shaft inside the crushing box, an electric push rod is installed on the horizontal plate, and an extrusion plate is provided below the horizontal plate. The output end of the electric push rod passes through the horizontal plate and is fixedly installed on the extrusion plate; the extrusion plate is generally L-shaped.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the extension and retraction of the cylinder output end during one working process can make the plastic bottles feed evenly, avoiding the problem of a large amount of material being fed at one time, which would cause the feed inlet to accumulate and exceed the effective crushing range of the crushing blades. This ensures that the plastic bottles always enter the crushing process in a uniform amount that matches the processing capacity of the blades, ensuring that the crushing blades are always in a highly efficient working state, significantly reducing the downtime for cleaning caused by accumulation, and increasing the crushing throughput per unit time. 2. In this utility model, the plastic bottle can be crushed a second time by the drive roller and the crushing blade on the rotating shaft, which greatly improves the fineness of the crushed plastic bottle. At the same time, the fixed plate sets up to distribute the raw materials after the first crushing, providing a decentralized and small-batch feeding basis for the second crushing stage, and preventing the accumulation problem from occurring again in subsequent processing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3 As shown, this utility model provides a plastic bottle waste crushing device with uniform feeding, including a crushing box 1. A feeding hopper 11 is fixedly installed on the top of the crushing box 1. An inclined feeding plate 12 is fixedly installed above the inner wall of the feeding hopper 11. A movable plate 13 is provided on the side of the feeding hopper 11 opposite to the feeding plate 12. A rotating rod 14 is rotatably provided at one end of the movable plate 13 near the inner wall of the feeding hopper 11. Both ends of the rotating rod 14 rotate through the feeding hopper 11. A worm gear 15 is fixedly installed at one end of the rotating rod 14 located on the outer wall of the feeding hopper 11. A worm 16 is meshed and connected below the worm gear 15. A drive gear 17 is fixedly installed at the end of the worm 16. A toothed plate 18 is meshed on the drive gear 17. A vertically arranged cylinder 19 is fixed near the toothed plate 18 on the wall. The output end of the cylinder 19 is coaxially fixed on the toothed plate 18. Two symmetrically arranged inclined plates 2 are fixed at the bottom of the feed hopper 11. Two symmetrically arranged drive rollers 21 are rotatably arranged in the middle of the two inclined plates 2 inside the crushing box 1. Crushing blades 22 are installed on the drive rollers 21 in a ring. The crushing blades 22 on the two drive rollers 21 are staggered. A fixed plate 3 in an inverted V shape is fixed below the drive rollers 21 inside the crushing box 1. A rotating shaft 31 is rotatably arranged at one bottom end of the fixed plate 3 inside the crushing box 1. The same crushing blades 22 as those installed on the drive rollers 21 are fixed on the rotating shaft 31.

[0016] Limiting blocks 181 are fixedly provided on the outer wall of the feed hopper 11 at the upper and lower ends of the toothed plate 18. The upper and lower ends of the toothed plate 18 move through the limiting blocks 181. The limiting blocks 181 mainly limit the vertical movement of the toothed plate 18, so that it moves up and down stably and prevents the toothed plate 18 from disengaging from the drive gear 17.

[0017] Two drive rollers 21 pass through one end of the crushing box 1 and are connected by two meshing transmission gears 23. A first motor 24 is fixedly installed on the outer wall of the crushing box 1 near the drive rollers 21. The output end of the first motor 24 is coaxially fixed on the drive rollers 21. The two transmission gears 23 mainly enable the two drive rollers 21 to rotate in opposite directions at the same time, thereby controlling the crushing blades 22 to crush the plastic bottles that fall into the middle. The first motor 24 mainly provides power for the rotation of the drive rollers 21, making it easy for the operator to control.

[0018] Two rotating shafts 31 are connected at one end outside the crushing box 1 by a belt 33. The belt 33 drives both rotating shafts 31 to rotate. It is worth noting that the two rotating shafts 31 are specifically driven by a synchronous pulley and a synchronous belt. For the sake of convenience, the text uses belt 33 drive. A second motor 34 is fixedly installed on the outer wall of the crushing box 1 near one of the rotating shafts 31. The output end of the second motor 34 is coaxially fixed on the rotating shaft 31. The second motor 34 mainly provides power for the rotation of the rotating shaft 31, which is convenient for the operator to operate.

[0019] A horizontal plate 4 is fixedly installed above the rotating shaft 31 inside the crushing box 1. An electric push rod 41 is installed on the horizontal plate 4. A pressing plate 42 is installed below the horizontal plate 4. The output end of the electric push rod 41 passes through the horizontal plate 4 and is fixedly installed on the pressing plate 42. The electric push rod 41 pushes the pressing plate 42 downward, so that the plastic bottle is stably squeezed and moved downward, so that the crushing blade 22 on the rotating shaft 31 crushes the plastic bottle.

[0020] The extrusion plate 42 is L-shaped. This design is intended to prevent the plastic bottle being fed through the fixed plate 3 from moving upward after the extrusion plate 42 moves downward. The vertical design allows the plastic bottle to enter the crushing blade 22 on the rotating shaft 31 intact for secondary crushing.

[0021] Working principle: During use, the operator can put the plastic bottles to be crushed into the feed hopper 11 at once. Initially, the movable plate 13 in the feed hopper 11 abuts against the discharge plate 12, preventing the plastic bottles from being discharged normally. As the cylinder 19 is activated, its output end retracts, which in turn moves the toothed plate 18 downward. During this process, the toothed plate 18 drives the drive gear 17 and the worm gear 16 to drive the worm wheel 15 to rotate clockwise, thereby driving the rotating rod 14 to move the movable plate 13 downward. At this point, the movable plate 13 and the discharge plate 12 will open up. At this time, the plastic bottle above will fall through the open notch between the two drive rollers 21 below. However, as the output end of the cylinder 19 extends, the toothed plate 18 will control the drive gear 17 to rotate counterclockwise, which will cause the worm 16 to drive the worm wheel 15 to rotate the rotating rod 14 counterclockwise and return to its original position. The notch between the movable plate 13 and the feeding plate 12 will be closed, and the feeding will stop. Through the above operation, the plastic bottle can be fed intermittently, so that the plastic bottle is fed evenly and avoids the one-time accumulation of feeding, which affects the crushing efficiency of the crushing blade 22. As the plastic bottle falls onto the crushing blade 22, the first motor 24 starts and, in conjunction with two meshing transmission gears 23, drives the two drive rollers 21 to rotate simultaneously in opposite directions. This causes the crushing blades 22 to rotate in opposite directions, crushing the falling plastic bottle. The crushed plastic bottle falls from below the drive rollers 21, but thanks to the fixed plate 3, the crushed plastic bottle is split into two parts and falls to both ends of the fixed plate 3. This step reduces the amount of crushed plastic bottle accumulating. Subsequently, the second motor 34 drives the rotating shaft 31 to rotate, causing the crushing blades 22 fixed on the rotating shaft 31 to rotate. In conjunction with the electric push rod 41, the squeezing plate 42 is continuously pushed so that the plastic bottle contacts the crushing blades 22 on the rotating shaft 31, performing a secondary crushing operation on the batch of plastic bottles. This further improves the crushing effect of the plastic bottle and facilitates subsequent pulverization.

The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
