Description

Technical Field

[0001] This utility model relates to the field of plastic granulation technology, specifically to a plastic granulation and molding equipment. Background Technology

[0002] In the process of recycling plastics, waste plastics are usually heated and melted to make plastic pellets for reuse, making them raw materials for plastic products. Plastic products thus have the advantage of being reusable. Currently, plastic raw materials are granulated using plastic pelletizers.

[0003] Currently, most existing granulation equipment still has certain drawbacks in the process of preparing plastic granules. Because the product is granular and a large number of plastic granules are concentrated in one place, the plastic granules are prone to sticking together, which is not conducive to the preparation and molding of plastic granules and has a certain impact on the processing. Utility Model Content

[0004] The purpose of this invention is to provide a plastic granulation and molding equipment to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic granulation and molding equipment, including a cooling water tank, a cylinder fixedly installed on the top of the cooling water tank via a support frame, a material conveying mechanism inside the cylinder, and a granulation disc fixedly connected to one end of the cylinder, a row of granulation holes on the granulation disc, a cutting mechanism on the top of the granulation disc, a wave-generating blowing mechanism on one side of the cooling water tank, a discharge port on the other side of the cooling water tank, a water collection frame fixedly installed on one side of the cooling water tank corresponding to the discharge port, a filter plate fixedly installed inside the water collection frame, and a collection box located on one side of the cooling water tank below the water collection frame. The filter plate is used to intercept and guide the plastic granules discharged from the cooling water tank, directing them into the collection box for unified collection.

[0006] As a further description of the above technical solution:

[0007] The feeding mechanism includes a feeding motor fixedly installed at one end of the barrel. The output end of the feeding motor is fixedly connected to a spiral feeding rod. The feeding mechanism is used to push and convey the molten plastic in the barrel to one side of the granulation disc.

[0008] As a further description of the above technical solution:

[0009] The top of the barrel is fixedly connected to a hopper, which facilitates the addition of molten plastic into the barrel.

[0010] As a further description of the above technical solution:

[0011] The cutting mechanism includes a pelletizing motor and a guide rod fixedly mounted on the pelletizing disc. A drive arm is fixedly connected to the output end of the pelletizing motor. A connecting rod is hinged to one end of the drive arm away from the output end of the pelletizing motor. A cutter is hinged to the other end of the connecting rod. Guide rings are fixedly connected to both the front and rear ends of the cutter. The guide rings are movably sleeved on the outside of the guide rod. The cutting mechanism is used to cut the plastic on the extrusion pelletizing disc to form plastic pellets.

[0012] As a further description of the above technical solution:

[0013] The wave-making and blowing mechanism includes a water pump fixedly installed on one side of the cooling water tank. The water pump's inlet end is fixedly connected to a water suction pipe, and the other end of the water suction pipe is connected to the bottom end of a water collection frame. The water pump's outlet end is fixedly connected to a drain pipe, and the other end of the drain pipe is fixedly connected to a diversion pipe. The diversion pipe has several water outlet holes on the side away from the drain pipe. The wave-making and blowing mechanism is used to push and transport the plastic particles floating in the cooling water tank to the right, which can prevent the plastic particles that fall into the cooling water tank from accumulating and sticking together.

[0014] As a further description of the above technical solution:

[0015] The drain pipe is fixedly installed on the left side of the inner wall of the cooling water tank and is on the same horizontal plane as the bottom of the inner wall of the discharge port.

[0016] As a further description of the above technical solution:

[0017] A semiconductor refrigeration chip is embedded on one side of the cooling water tank. The cooling end of the semiconductor refrigeration chip is located inside the cooling water tank, while its heat dissipation end is located outside the cooling water tank.

[0018] The beneficial effects of the plastic granulation and molding equipment provided by this utility model in the above technical solution are as follows:

[0019] This invention uses a water pump to draw water from the collection frame via a suction pipe and then transports it to a distribution pipe via a drain pipe, finally allowing the water to flow out from the outlet. This causes the cooling water in the cooling water tank to flow from left to right, thus conveying the plastic particles that fall into the cooling water tank to the right and ultimately draining them into the collection frame. The filter plate in the collection frame intercepts the plastic particles and guides them into a collection box. The continuous wave action pushes the plastic particles falling into the cooling water tank to the right, preventing their accumulation and effectively avoiding their sticking together.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0030] Please see Figure 1-4 This embodiment provides a plastic granulation and molding equipment, including a cooling water tank 1. A cylinder 2 is fixedly installed on the top of the cooling water tank 1 via a support frame. A material conveying mechanism is provided inside the cylinder 2, and a granulation disc 3 is fixedly connected to one end of the cylinder 2. A row of granulation holes 4 are opened on the granulation disc 3. A cutting mechanism is also provided on the top of the granulation disc 3. A wave-making and blowing mechanism is provided on one side of the cooling water tank 1, and a discharge port 5 is opened on the other side of the cooling water tank 1. A water collection frame 6 is fixedly installed on one side of the cooling water tank 1 at the position corresponding to the discharge port 5. A filter plate 7 is fixedly installed inside the water collection frame 6. A collection box 8 is provided on one side of the cooling water tank 1 below the water collection frame 6.

[0031] The feeding mechanism includes a feeding motor 9 fixedly installed at one end of the barrel 2. The output end of the feeding motor 9 is fixedly connected to a spiral feeding rod (not shown in the figure). The feeding mechanism is used to push and convey the molten plastic in the barrel 2 to one side of the granulation disc 3. The top of the barrel 2 is fixedly connected to a hopper 11, which facilitates the addition of molten plastic into the barrel 2.

[0032] The cutting mechanism includes a pelletizing motor 12 and a guide rod 13 fixedly mounted on the pelletizing disc 3. A drive arm 14 is fixedly connected to the output end of the pelletizing motor 12. A connecting rod 15 is hinged to one end of the drive arm 14 away from the output end of the pelletizing motor 12. A cutter 16 is hinged to the other end of the connecting rod 15. Guide rings 17 are fixedly connected to both the front and rear ends of the cutter 16. The guide rings 17 are movably sleeved on the outside of the guide rod 13. The rotation of the output end of the pelletizing motor 12 drives the drive arm 14 to rotate, and the connecting rod 15 drives the cutter 16 to move up and down reciprocally, thus pelletizing the plastic extruded from the pelletizing hole 4. The cooperation of the guide rod 13 and the guide ring 17 can limit the movement of the cutter 16 and improve the stability of the cutter 16 when it moves up and down.

[0033] The wave-generating material blowing mechanism includes a water pump 18 fixedly installed on one side of the cooling water tank 1. The water inlet end of the water pump 18 is fixedly connected to a water suction pipe 19. The other end of the water suction pipe 19 is connected to the bottom end of the water collection frame 6. The water outlet end of the water pump 18 is fixedly connected to a drain pipe 20. The other end of the drain pipe 20 is fixedly connected to a diversion pipe 21. Several water outlet holes 10 are opened on the side of the diversion pipe 21 away from the drain pipe 20. The drain pipe 20 is fixedly installed on the left side of the inner wall of the cooling water tank 1 and is at the same level as the bottom end of the inner wall of the discharge port 5.

[0034] A semiconductor cooling chip 22 is embedded on one side of the cooling water tank 1. The cooling end of the semiconductor cooling chip 22 is located inside the cooling water tank 1, and its heat dissipation end is located outside the cooling water tank 1. The semiconductor cooling chip 22 can cool the water in the cooling water tank 1, thereby ensuring that the water in the cooling water tank 1 is at a suitable temperature and avoiding the cooling effect being affected by the temperature rise of the water in the cooling water tank 1 after cooling the plastic particles for a period of time.

[0035] Working principle: During use, the operator first injects clean water into the cooling water tank 1 until the water level in the cooling water tank 1 is at the same level as the bottom of the inner wall of the discharge port 5, and injects an appropriate amount of clean water into the water collection frame 6. Then, the melted plastic is added into the hopper 11 and enters the barrel 2 through the hopper 11. At the same time, the conveying motor 9 is started. The output end of the conveying motor 9 rotates and drives the spiral conveying rod to rotate, conveying the melted plastic to one end close to the granulation disc 3 until the melted plastic is squeezed out of the granulation hole 4 to the appropriate size. At the same time, the output end of the pelletizing motor 12 rotates and drives the drive arm 14 to rotate, and drives the cutter 16 to move up and down through the connecting rod 15 to pelletize the plastic squeezed out of the granulation hole 4. The cut plastic pellets fall into the cooling water tank 1 and are cooled by the cooling water in the cooling water tank 1.

[0036] Simultaneously, by starting the water pump 18, water is drawn from the water collection frame 6 using the water suction pipe 19 and transported to the diversion pipe 21 through the drain pipe 20, finally flowing out from the water outlet 10. This causes the cooling water in the cooling water tank 1 to flow from left to right (i.e., the surface of the cooling water in the cooling water tank 1 has waves from left to right), thereby transporting the plastic particles that fall into the cooling water tank 1 to the right and finally discharging them into the water collection frame 6. The filter plate 7 in the water collection frame 6 intercepts the plastic particles and guides them to the collection box 8. The waves continuously push the plastic particles that fall into the cooling water tank 1 to the right, which can prevent the accumulation of plastic particles and effectively avoid the accumulation and adhesion of plastic particles.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
