Description

Technical Field

[0001] This utility model relates to the field of plastic crusher technology, and in particular to a plastic crusher and its protective structure. Background Technology

[0002] A plastic crusher is a mechanical device used to crush plastic products. Through internal blades or hammers, it uses high-speed rotation, impact, and shearing to break large pieces of plastic, such as plastic bottles, plastic buckets, and plastic films, into smaller pieces or granules. The crushed plastic is easier to recycle and reuse, and can be reprocessed into new plastic products, achieving resource recycling and reducing environmental pollution.

[0003] When using a plastic crusher, operators need to feed plastic waste into the inlet at a uniform speed, and the crushed material will be discharged from the outlet. To prevent jamming, the feeding speed should be controlled to avoid feeding too much at once and to prevent material from accumulating in the crushing chamber.

[0004] The shortcomings of the existing technical solutions are as follows: plastic waste comes in various forms, sizes, and hardnesses, making it difficult to accurately determine the appropriate amount to be fed each time. Furthermore, operation often requires attention to other aspects, making it impossible to focus solely on the amount of material fed and control the feeding speed. If the feeding is too fast, the material tends to accumulate in the crushing chamber, leading to excessive motor load, potentially burning out the motor, and also causing blockage of the crushing chamber, thus affecting crushing efficiency. Utility Model Content

[0005] This utility model provides a plastic crusher and protective structure, which can solve the problem in the prior art that it is difficult for workers to control the feeding speed, which easily causes materials to accumulate in the crushing chamber and affect the crushing efficiency.

[0006] A protective structure for a plastic crusher includes a feed box, inside which a vibrating plate is fitted. A vibration assembly for driving the vibrating plate to vibrate is located at the bottom of the vibrating plate. A material-pushing wheel is rotatably mounted inside the feed box, positioned above the vibrating plate. A gap exists between the material-pushing wheel and the vibrating plate for material to pass through. A drive assembly for driving the material-pushing wheel to rotate is mounted on the feed box. The drive assembly can drive the bottom of the material-pushing wheel to rotate in the opposite direction to the material conveying direction.

[0007] As a further embodiment of this utility model: multiple sets of lever plates are fixedly arranged at equal intervals around the side of the feeding wheel, each set of lever plates is arc-shaped, and the arc-shaped convex surface of each set of lever plates is in the same direction of rotation as the feeding wheel.

[0008] As a further embodiment of this utility model: protective discs that cooperate with the inner wall of the guide box are fixedly provided on both sides of the feeding wheel.

[0009] As a further embodiment of this utility model: the vibrating plate is vertically arranged on both sides and cooperates with the inner wall of the guide box.

[0010] As a further embodiment of this utility model: the vibrating plate is movably connected to the feed box near the feed box inlet side, the vibrating assembly includes a crankshaft rotatably disposed inside the crushing box, a rotating sleeve is rotatably disposed on the crankshaft, a connecting member is movably connected to the rotating sleeve, the connecting member is movably connected to the bottom of the vibrating plate, and the crankshaft is in transmission cooperation with the drive assembly.

[0011] As a further embodiment of this utility model: the bottom wall of the guide box below the vibrating plate is inclined inward along the material feeding port of the guide box, and there is a gap between the vibrating plate and the bottom wall of the guide box below the vibrating plate.

[0012] As a further embodiment of this utility model: a scraper that cooperates with the feeding wheel is horizontally fixed above the guide box.

[0013] A plastic crusher with a protective structure includes a support base, a crushing box on the support base, a crushing disc and a fixed blade holder inside the crushing box, and a feed box fixedly sleeved above the crushing box.

[0014] As a further embodiment of this utility model: a driving mechanism is provided on the support base, the driving mechanism includes a motor fixedly mounted on the support base, the output end of the motor being coaxially and fixedly connected to the central shaft of the crushing disc, the other end of the central shaft of the crushing disc being rotatably connected to a first rotating wheel after passing through the crushing box, a second transmission wheel being fixedly connected to both sides of the crankshaft, a third transmission wheel being coaxially and fixedly mounted on one side of the feeding wheel, a first transmission belt being provided on the first rotating wheel and a set of second transmission wheels, and a second transmission belt being provided on the third transmission wheel and a set of second transmission wheels.

[0015] As a further embodiment of this utility model: a support member is fixedly provided between the lower end of the feed box inlet and the front side of the crushing box.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, the bottom of the feeding wheel rotates in the opposite direction to the material conveying, and in conjunction with the equidistant, arc-shaped convex plates aligned with the rotation direction, it controls the amount of material entering the crushing chamber. When too much material accumulates in the feed box, the feeding wheel effectively pushes the material outward, allowing only a portion of the material to pass through the gap between it and the vibrating plate, preventing a large influx of material into the crushing chamber and causing accumulation, thus improving crushing efficiency. Simultaneously, it reduces the risk of material blockage in the feed box, ensuring smooth material flow and making the entire crushing process more stable and efficient.

[0018] 2. In use, the vibrating plate generates vibration, causing the material to slowly move along its surface into the feed box, achieving orderly material conveying and ensuring that the material can enter the crushing chamber evenly. The feed box, in conjunction with the feeding wheel, reduces the risk of material blockage in the feed box and ensures smooth material flow within it. Attached Figure Description

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1 to 5 As shown in the figure, this utility model provides a plastic crusher and protective structure, including a feed box 2, inside which a vibrating plate 4 is installed. A vibration component 7 is installed at the bottom of the vibrating plate 4, the main function of which is to drive the vibrating plate 4 to vibrate. When material is fed into the feed box 2, it will slowly move along the surface of the vibrating plate 4 to the inside of the feed box 2 under the vibration of the vibrating plate 4, thereby achieving orderly material conveying.

[0028] Inside the feed box 2, a material guide wheel 3 is rotatably mounted. In this embodiment, the material guide wheel 3 is used for limited material conveying, which can effectively avoid clogging problems. A drive assembly is provided on the feed box 2 to drive the material guide wheel 3 to rotate. This drive assembly can drive the bottom of the material guide wheel 3 to rotate in the opposite direction to the material conveying direction. To more clearly illustrate the structure of the material guide wheel 3, as follows... Figure 3 As shown, multiple sets of eccentric plates are fixedly arranged at equal intervals around the side of the feeding wheel 3. Each set of eccentric plates is arc-shaped, and the convex surface of each set of eccentric plates is aligned with the rotation direction of the feeding wheel 3. The feeding wheel 3 is located above the vibrating plate 4, and there is a certain gap between the feeding wheel 3 and the vibrating plate 4. This gap is specifically designed for material passage. During actual operation, when too much material accumulates inside the feed box 2, the feeding wheel 3 will push the material outward, allowing only a portion of the material to enter the feed box 2 through the gap between the feeding wheel 3 and the vibrating plate 4, thus completing the crushing operation. In this way, the amount of material entering the crushing chamber is effectively controlled, avoiding the problem of material accumulation.

[0029] To prevent plastic materials from getting stuck on both sides of the feeding wheel 3 and affecting its normal operation, protective discs 301 that mate with the inner wall of the guide box 2 are fixedly installed on both sides of the feeding wheel 3. The protective discs 301 can effectively prevent materials from getting stuck between the feeding wheel 3 and the inner wall of the guide box 2, ensuring that the feeding wheel 3 can always maintain a smooth operating state.

[0030] The vibrating plate 4 is vertically arranged on both sides, and its ends are sloped. This design allows the vibrating plate 4 to better fit with the inner wall of the guide box 2, thereby reducing the occurrence of material entering the bottom of the vibrating plate 4 along its sides. The bottom wall of the guide box 2 below the vibrating plate 4 is inclined inwards along the feed inlet of the guide box 2. Simultaneously, there is a certain gap between the vibrating plate 4 and the bottom wall of the guide box 2 below it. This design facilitates the vibration of the vibrating plate 4 and allows small materials entering the bottom of the vibrating plate 4 to be smoothly fed into the guide box 2 along the feed inlet.

[0031] The vibrating plate 4 is movably connected to the feed box 2 near the inlet, while the vibrating assembly 7 is located at the bottom of the vibrating plate 4. A certain gap exists between the vibrating assembly 7 and the bottom of the feed inlet of the feed box 2 to prevent mutual interference and ensure stable operation of the entire structure. The vibrating assembly 7 includes a crankshaft 701 rotatably mounted inside the crushing chamber 1, a rotating sleeve 702 rotatably mounted on the crankshaft 701, and a connecting member 703 movably connected to the rotating sleeve 702. The connecting member 703 is movably connected to the bottom of the vibrating plate 4. Furthermore, the crankshaft 701 is driven by a drive assembly. During actual operation, the drive assembly drives the crankshaft 701 to rotate, which in turn drives the rotating sleeve 702 to perform circular motion. The rotating sleeve 702 then drives the connecting member 703 and the end of the vibrating plate 4 to reciprocate, thereby achieving a vibration effect on the vibrating plate 4. This effectively promotes material conveying and ensures that the material enters the crushing chamber uniformly.

[0032] In another specific embodiment, a scraper 8, which cooperates with the feeding wheel 3, is horizontally fixed above the feed box 2. When the feeding plate on the feeding wheel 3 passes under the scraper 8, the scraper 8 performs its cleaning function, removing material stuck or adhering to the end of the feeding plate. In this way, material accumulation on the feeding plate can be effectively avoided, thus preventing the material conveying operation from being affected and ensuring that the feeding wheel 3 can always maintain a good working condition.

[0033] This solution also provides a plastic crusher, which includes a support base 5, on which a crushing box 1 and a drive mechanism 6 are mounted. The crushing box 1 contains a crushing disc and a fixed blade holder. The drive mechanism 6 can drive the crushing disc to move relative to the fixed blade holder, thereby crushing the material. The specific structure of the crushing disc relative to the fixed blade holder is within the scope of existing technology and will not be elaborated here. The aforementioned feed box 2 is fixedly mounted above the crushing box 1; the two work closely together to complete the plastic crushing operation.

[0034] The drive mechanism 6 includes a motor 601 fixedly mounted on a support base 5. The output end of the motor 601 is coaxially and fixedly connected to the central shaft of the crushing disc. The other end of the central shaft of the crushing disc rotates through the crushing chamber 1 and is coaxially and fixedly connected to a first rotating wheel 602. Both sides of the crankshaft 701 rotate through the guide box 2 and are each fixedly connected to a second transmission wheel 603. One side of the feeding wheel 3 rotates through the guide box 2 and is coaxially and fixedly connected to a third transmission wheel 604. A first transmission belt is fitted onto the first rotating wheel 602 and a set of second transmission wheels 603, and a second transmission belt is fitted onto the third transmission wheel 604 and a set of second transmission wheels 603. In actual use, the motor 601 drives the crushing disc to rotate, which in turn drives the first rotating wheel 602 to rotate. The first rotating wheel 602 drives the set of second transmission wheels 603 to rotate via the first transmission belt, which in turn drives the crankshaft 701 to rotate, achieving the vibration effect on the vibrating plate 4. Meanwhile, another set of second transmission wheels 603 drives the third transmission wheel 604 to rotate via the second transmission belt. The third transmission wheel 604 drives the material feeding wheel 3 to rotate, thereby achieving the material limiting effect. This transmission method cleverly utilizes a single motor 601 to achieve the coordinated operation of multiple components.

[0035] In another specific embodiment, to enhance the stability of the feed box 2, a support member can be fixedly installed between the lower end of the feed box 2's inlet and the front side of the crushing box 1. The support member effectively prevents the feed box 2 from deforming under vibration, ensuring the long-term stable operation of the entire plastic crusher.

[0036] Working principle: When the plastic crushing operation begins, the worker puts the material into the feed box 2. The material first falls onto the vibrating plate 4, which then begins to vibrate under the action of the vibrating component 7. The vibration of the vibrating plate 4 causes the material to slowly move along its surface into the feed box 2, achieving orderly material conveying.

[0037] Meanwhile, the feeding wheel 3 inside the feed box 2 begins to rotate under the drive of the drive assembly. The rotation direction of the feeding wheel 3 is opposite to the bottom direction of material conveying. Under normal material conveying conditions, the material can smoothly enter the feed box 2 through the gap between the feeding wheel 3 and the vibrating plate 4. However, when too much material accumulates inside the feed box 2, the feeding wheel 3 will play its role in limiting the material flow. Since the rotation direction of the feeding wheel 3 is opposite to the material conveying direction, it will push the material outward, allowing only a portion of the material to pass through the gap and enter the feed box 2 to complete the crushing operation. In this way, the amount of material entering the crushing chamber is effectively controlled, preventing material accumulation in the crushing chamber, thus ensuring crushing efficiency, and also preventing blockage inside the feed box 2.

[0038] The vibration of the vibrating plate 4 is achieved by the vibration assembly 7. The crankshaft 701 in the vibration assembly 7 starts to rotate under the drive of the drive assembly, and the rotating sleeve 702 on the crankshaft 701 performs a circular motion accordingly. The rotating sleeve 702 drives the end of the vibrating plate 4 to reciprocate through the movable connecting member 703, thereby causing the vibrating plate 4 to vibrate.

[0039] A scraper 8, which works in conjunction with the feeding wheel 3, is horizontally fixed above the feed box 2. When the feed plate on the feeding wheel 3 passes under the scraper 8, the scraper 8 cleans the material stuck or adhering to the end of the feed plate. This prevents material from accumulating on the feed plate, thus avoiding affecting the feeding operation and ensuring that the feeding wheel 3 always maintains a good working condition.

[0040] The motor 601 in the drive mechanism 6 drives the crushing disc to rotate, and the first rotating wheel 602, which is coaxially fixed to the other end of the central shaft of the crushing disc, rotates accordingly. The first rotating wheel 602 drives a set of second transmission wheels 603 to rotate via a first transmission belt, which in turn drives the crankshaft 701 to rotate, thus achieving the vibration effect on the vibrating plate 4. At the same time, another set of second transmission wheels 603 drives a third transmission wheel 604 to rotate via a second transmission belt, and the third transmission wheel 604 drives the feeding wheel 3 to rotate, thus achieving the material limiting effect of the feeding wheel 3.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
