Description

Technical Field

[0001] This utility model relates to the technical field of plastic crushing, and in particular to a device for collecting and preventing spillage of crushed plastic material. Background Technology

[0002] Plastic shredding material collection refers to the process of physically crushing various waste plastic products or plastic scraps generated in industrial production using specialized crushing equipment, transforming them into smaller, more uniform particles or fragments, and then systematically collecting and processing these crushed materials. This process is not only a crucial link in the plastic recycling chain, effectively solving the problems of large land occupation and inconvenient transportation of waste plastics, but also provides the necessary raw material preparation for subsequent recycling processes such as melt granulation and remolding. It is an important basic operation for realizing the circular utilization of plastic resources and environmental protection.

[0003] In the practical application of plastic crushers, the design of the discharge stage directly affects the equipment's working efficiency and user experience. Currently, the commonly used inclined discharge pipe structure has obvious defects. Its tilt angle design often makes it difficult to balance the needs of smooth discharge and controllable material drop. When the tilt angle is small, the plastic crushed material is prone to accumulate in the pipe due to increased flow resistance under the action of gravity, which will cause blockage problems. This not only affects continuous operation, but also requires frequent shutdowns for cleaning. When the tilt angle is too large or even close to vertical, although the crushed material can fall quickly, the excessive speed will cause it to splash outward at the discharge port due to inertia, causing material spillage. This not only increases the difficulty of material recovery, but also easily pollutes the working environment and reduces the cleanliness and safety of the production site. Utility Model Content

[0004] In view of the problem that the inclined discharge pipe of the existing plastic crusher is difficult to balance between preventing blockage and avoiding spillage, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a plastic crushing material collection and spill prevention device, which aims to solve the problem that the inclined discharge pipe of the existing plastic crusher is difficult to balance between preventing blockage and avoiding spillage.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic crushed material collection and anti-spillage device, including a fixed bracket, a discharge pipe and a discharge plate, and further including a material slowing mechanism and a vibration mechanism. The material slowing mechanism includes a spiral guide plate rotatably installed in the lower part of the discharge pipe. The spiral guide plate is rotatably installed in the lower part of the discharge pipe through a rotating ring. A drive motor is fixedly installed on one side of the discharge pipe. The lower output end of the drive motor is driven by a drive shaft to install a drive gear. The vibration mechanism includes a collision block that is rotatably mounted on the lower surface of the discharge plate.

[0007] In a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, a toothed block is fixedly installed on the outer surface of the rotating ring, and the rotating ring meshes with the drive gear through the toothed block.

[0008] In a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, the discharge plate is rotatably mounted on the inner side of the fixed bracket via a rotating shaft.

[0009] As a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, the discharge plate has grooves on both sides, and a rotating rod is slidably installed inside the groove, and the rotating rod is fixedly installed inside the fixed bracket.

[0010] In a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, the discharge pipe is fixedly installed at the lower part of the fixed bracket.

[0011] In a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, the upper output end of the drive motor is equipped with a first bevel gear via a transmission shaft.

[0012] As a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, the inner side of the fixed bracket is rotatably mounted with a second bevel gear through a connecting rod and a connecting rod, and the second bevel gear and the first bevel gear mesh with each other.

[0013] As a preferred embodiment of the plastic crushed material collection and spill prevention device of this utility model, a transmission gear is fixedly installed at one end of the connecting rod and one end of the collision block, and the two sets of transmission gears are connected to each other by a transmission belt.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its specially designed slowing mechanism, allows the plastic pulverized material to descend slowly via a spiral guide plate after entering the discharge pipe through the discharge plate. Simultaneously, a drive motor rotates the active gear, causing the rotating ring to rotate and ultimately rotating the spiral guide plate. This prevents the plastic pulverized material from clogging at the slowing mechanism during its descent, fundamentally solving the problem of spillage caused by excessively rapid discharge. Furthermore, the continuously rotating spiral structure actively pushes the material, preventing it from accumulating and clogging within the slowing mechanism, ensuring a continuous and stable discharge process, and significantly improving the equipment's working efficiency and reliability.

[0015] 2. This utility model uses a vibration mechanism to drive a motor to rotate a drive gear via a transmission shaft. Simultaneously, the first bevel gear drives the second bevel gear to rotate, thereby rotating the transmission gear. The transmission gear, through a transmission belt, drives a collision block to rotate on the lower surface of the discharge plate. The collision block impacts the lower surface of the discharge plate, causing the discharge plate to rotate slightly around the axis, thus vibrating the discharge plate. This effectively prevents the crushed material from sticking or bridging at the discharge port, further ensuring the smoothness of the discharge. Working in conjunction with the slowing mechanism, it ensures the stability and reliability of the entire discharge process. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-2This is the first embodiment of the present invention, which provides a plastic crushed material collection and anti-spillage device. This plastic crushed material collection and anti-spillage device includes a fixed bracket 1, a discharge pipe 5 and a discharge plate 8, and also includes a material slowing mechanism 6 and a vibration mechanism 7. The material slowing mechanism 6 includes a spiral guide plate 601 rotatably installed in the lower part of the discharge pipe 5. The spiral guide plate 601 is rotatably installed in the lower part of the discharge pipe 5 through a rotating ring 602. A drive motor 604 is fixedly installed on one side of the discharge pipe 5. The lower output end of the drive motor 604 is driven by a drive gear 606 through a transmission shaft 605.

[0020] A toothed block 603 is fixedly installed on the outer surface of the rotating ring 602, and the rotating ring 602 meshes with the drive gear 606 through the toothed block 603.

[0021] During use, the drive motor 604 starts, and its lower output end drives the drive gear 606 to rotate through the transmission shaft 605. Since the drive gear 606 meshes with the tooth block 603 fixed on the outer surface of the rotating ring 602, the rotation of the drive gear 606 drives the rotating ring 602 and the spiral guide plate 601 fixed thereto to rotate together in the discharge pipe 5. When the plastic crushed material enters the discharge pipe 5 from the discharge plate 8, it will fall onto the continuously rotating spiral guide plate 601. Under its own gravity, the material moves downward along the spiral track of the spiral guide plate 601, and its falling path is significantly extended, thereby slowing down the speed. At the same time, the continuous rotation of the spiral guide plate 601 generates an active pushing force, which can effectively prevent the material from stagnating or accumulating in the slowing part, ensuring that the material can pass through the discharge pipe 5 smoothly, continuously and without blockage, fundamentally solving the problem of spillage caused by falling too fast. Example 2

[0022] Reference Figures 3-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the vibration mechanism 7 includes a collision block 707 that is rotatably mounted on the lower surface of the discharge plate 8.

[0023] The discharge plate 8 is rotatably mounted on the inner side of the fixed bracket 1 via the rotating shaft 2.

[0024] Both sides of the discharge plate 8 are provided with sliding grooves 3, and a rotating rod 4 is slidably installed inside the sliding groove 3. The rotating rod 4 is fixedly installed inside the fixed bracket 1.

[0025] The discharge pipe 5 is fixedly installed at the lower part of the fixed bracket 1.

[0026] The upper output end of the drive motor 604 is equipped with a first bevel gear 701 via a transmission shaft 605.

[0027] The second bevel gear 702 is rotatably mounted on the inner side of the fixed bracket 1 via the connecting rod 704 and the connecting rod 703. The second bevel gear 702 meshes with the first bevel gear 701.

[0028] One end of the connecting rod 704 and one end of the collision block 707 are both fixedly mounted with transmission gears 705, and the two sets of transmission gears 705 are connected to each other by a transmission belt 706.

[0029] During operation, the drive motor 604 starts, and its upper output end drives the first bevel gear 701 to rotate through the transmission shaft 605. The first bevel gear 701 meshes with the second bevel gear 702, transmitting power and changing direction, driving the second bevel gear 702 to rotate. The second bevel gear 702 drives the transmission gear 705 at one end to rotate synchronously through the transmission of the connecting rod 703 and the connecting rod 704. The transmission gear 705 transmits power to another set of transmission gears 705 installed at one end of the collision block 707 through the transmission belt 706, thereby driving the collision block 707 to perform circular motion on the lower surface of the discharge plate 8. When the collision block 707 rotates to contact the lower surface of the discharge plate 8, an impact will occur, causing the discharge plate 8 to deflect slightly around the rotating shaft 2. This periodic vibration can destroy the adhesion between the material and the discharge plate 8, preventing it from forming bridges or blockages at the discharge port. Working together with the slowing mechanism 6, it further ensures the smoothness of the discharge.

[0030] The remaining structure is the same as that in Example 1.

[0031] Based on embodiments 1-2, the working principle of this utility model is as follows: The drive motor 604 starts, and its power is transmitted simultaneously in two directions through the transmission shaft 605. On one hand, the lower output shaft of the motor drives the drive gear 606 to rotate, which in turn meshes with the toothed block 603 on the outer side of the rotating ring 602, causing the spiral guide plate 601 installed in the discharge pipe 5 to start rotating at a uniform speed. When the plastic pulverized material enters the discharge pipe 5 from the discharge plate 8, it falls onto this continuously rotating spiral guide plate 601. The material no longer falls freely but spirals downwards along the spiral track, greatly extending its falling path and effectively controlling its speed. This fundamentally avoids the spillage problem caused by excessively fast falling. Simultaneously, the rotation of the spiral guide plate 601 can actively push the material, preventing blockage in the slow-moving section. On the other hand… On the other hand, the upper output shaft of the motor drives the first bevel gear 701 to rotate. The transmission direction is changed by the second bevel gear 702 that meshes with it. Then, through a series of transmission components such as the connecting rod 703, connecting rod 704, transmission gear 705 and transmission belt 706, the collision block 707 is finally driven to perform circular motion on the lower surface of the discharge plate 8. The collision block 707 periodically impacts the discharge plate 8, causing it to generate slight high-frequency vibration around the rotating shaft 2. This vibration can effectively break the adhesion and bridging of materials at the discharge port, ensuring that the materials at the inlet can smoothly enter the discharge pipe 5. The synergistic effect of the slowing mechanism 6 and the vibration mechanism 7, one controlling the falling speed and the other preventing inlet blockage, together ensures that the plastic crushed material can be continuously, stably and without spillage throughout the entire process from entering the discharge pipe 5 to the final discharge.
