Description

Technical Field

[0001] This utility model relates to the field of polymer plastics, and in particular to a polymer plastic pelletizing device. Background Technology

[0002] During the production of polymer plastic particles, after the pelletizing device cuts the strip extruded material into particles, the particles usually need to be screened using a vibrating screen. This not only removes impurities and defective products, but also grades the particles according to specifications, ensuring that the product quality meets the expected requirements.

[0003] Currently, the existing patent with publication number CN222590351U discloses a pelletizing device for producing polymer plastic particles, including a frame, a shell, a feeding hopper, a feeding shaft, a conveying roller, a cutting roller, and a discharge hopper. An end cover is installed at the discharge hopper, and the end cover is fixedly connected. It has a flexible cloth tube, and two support plates are installed at the bottom of the end cover. The support plates are fixedly connected to the end arc plates, and a counterweight rod is installed between the two end arc plates.

[0004] The pelletizing device of this application cuts extruded strips into pellets via a cutting blade, which are then discharged from a flexible cloth cylinder. This makes feeding more convenient and easier to integrate with a subsequent vibrating screen. Furthermore, the flexible cloth cylinder's design prevents material from bouncing during discharge. A support plate maintains the flexible cloth cylinder's shape for easier feeding, and a counterweight allows the end arc-shaped plate to abut against the vibrating screen. The screen's vibration then creates a slight shaking effect on the flexible cloth cylinder, further facilitating feeding.

[0005] While the aforementioned device has the advantages described above, it directly collects the plastic pellets after pelletizing them. However, during the pelletizing process, it is easy to generate debris and non-standard sized pellets, which in turn affects the overall pelletizing quality. Utility Model Content

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] In the attached diagram, all identical reference numerals refer to the same components.

[0017] As shown in Figures 1-5, this utility model provides a polymer plastic pelletizing device, including: a frame 1, a feeding frame 2 on the top of the frame 1, three guide plates 3 installed inside the feeding frame 2, a pelletizing assembly 4 on the top of the frame 1, and a protective shell on the top of the frame 1.

[0018] Furthermore, a discharge pipe 8 is provided on one side of the collection chamber 5. The inner bottom wall of the collection chamber 5 is cut obliquely towards the discharge pipe 8. A valve is provided at the connection between the discharge pipe 8 and the collection chamber 5. A sealing door is provided on one side of the collection chamber 5, and the sealing door is located above the discharge pipe.

[0019] Furthermore, a limit frame one is installed on the top of the frame 1, and the end of the rotating rod 408 away from the gear 403 and the gear 404 is rotatably connected to the limit frame one. A limit frame two is installed on one side of the collection chamber 5, and the connecting rod 703 is rotatably connected to the limit frame two.

[0020] Example 1 In this embodiment, the pelletizing assembly 4 includes a dual-shaft motor 401, gear 1 402, gear 2 403, gear 3 404, gear 405, mounting wheel 406, cutter 407, rotating rod 1 408, rotating rod 2 409, and guide roller 4010. A collection chamber 5 is provided on one side of the top of the frame 1, and a guide pipe 6 is provided between the collection chamber 5 and the protective shell. The dual-shaft motor 401 is installed on one side of the top of the frame 1. Gear 1 402 is installed on one rotating shaft of the dual-shaft motor 401. There are two rotating rods 1 408, which are arranged vertically. Gear 2 403 and gear 3 404 are respectively installed on one side of the two rotating rods 1 408. One end of one rotating rod 1 408 passes through gear 3 404 and is equipped with gear 405. The outer side of each part is equipped with a guide roller 4010. Inside the protective shell, a rotating rod 409 is rotatably installed. One end of the rotating rod 409 is connected to the other rotating shaft of the dual-axis motor 401. Mounting wheels 406 are installed on both sides of the outer side of the rotating rod 409. Multiple cutters 407 are installed on the outer side of the mounting wheels 406.

[0021] In this embodiment, gear 2 403 is located on top of gear 3 404, and gear 2 403 and gear 3 404 are meshed together, while gear 4 405 is meshed with gear 1 402.

[0022] Specifically, the dual-axis motor 401 drives gear 402 to rotate, which in turn drives gears 404 and 405 to rotate synchronously. Gear 404 drives gear 403 to rotate, which in turn drives rotating rod 408 and rotating rod 409 to rotate. The rotation of rotating rod 408 drives the guide roller 4010 to rotate for guiding the material. The rotation of rotating rod 409 drives the cutter 407 to rotate for granulation of the polymer plastic strip material.

[0023] Example 2 In this embodiment, a screening assembly 7 is also included. The screening assembly 7 includes a first pulley 701, a second pulley 702, a connecting rod 703, a toggle rod 704, a screen plate 705, and a synchronous belt. The first pulley 701 is installed at the end of the second rotating rod 409 away from the dual-axis motor 401. The connecting rod 703 is rotatably installed inside the collection chamber 5. One end of the connecting rod 703 passes through the collection chamber 5 and is equipped with the second pulley 702. The second pulley 702 communicates with the first pulley 701. Connected via synchronous belt drive.

[0024] Furthermore, four actuating rods 704 are installed on the outside of the connecting rod 703. The actuating rods 704 are symmetrically and equidistantly distributed. A screen plate 705 is installed inside the collecting chamber 5. The screen plate 705 has an arc-shaped structure.

[0025] Specifically, when the dual-shaft motor 410 drives the rotating rod 409 to rotate, it will drive the pulley 701 to rotate. Through the action of the synchronous belt, the pulley 702 and the connecting rod 703 will rotate, which in turn drives the actuating rod 704 to rotate, actuating the polymer plastic particles, and screening them through the sieve plate 705.

[0026] Working principle: The feed frame 2 at the top of the frame 1 is used to feed the polymer plastic strip raw material to be granulated. The three guide plates 3 installed inside the feed frame 2 play a guiding role, so that the strip raw material can enter the subsequent granulation stage smoothly and orderly, and prevent the raw material from being blocked or unevenly distributed.

[0027] When the dual-axis motor 401 mounted on one side of the top of the frame 1 starts, its rotating shaft drives gear 402 to rotate. Since gear 405 meshes with gear 402, the rotation of gear 402 drives gear 405 to rotate. Because gear 405 is mounted on a rotating rod 408, this rotating rod 408 rotates accordingly. Simultaneously, gears 403 and 404 on the two rotating rods 408 mesh, with gear 403 located on top of gear 404. When one rotating rod 408 rotates, the meshing of gears 403 and 404 causes the other rotating rod 408 to rotate as well, achieving linkage between the two rotating rods 408. This, in turn, drives the external guide roller 4010 to rotate, guiding the polymer plastic strip material.

[0028] The other rotating shaft of the dual-axis motor 401 is connected to one end of the rotating rod 409, driving the rotating rod 409 to rotate. The mounting wheels 406 installed on both sides of the rotating rod 409 rotate accordingly, and multiple cutters 407 are installed on the outside of the mounting wheels 406, thereby driving the cutters 407 to rotate.

[0029] The raw material exiting from the feed frame 2, guided by the guide roller 4010, enters the cutting area of ​​the cutter 407. The rotating cutter 407 cuts the raw material into granules, completing the pelletizing operation.

[0030] A pulley 701 is mounted on the end of the rotating rod 409 furthest from the dual-shaft motor 401. When the rotating rod 409 rotates, it drives the pulley 701 to rotate. The pulley 701 is connected to the pulley 702 at one end of the connecting rod 703 inside the collection chamber 5 via a synchronous belt, thereby transmitting power to the connecting rod 703 and causing it to rotate.

[0031] Four symmetrically spaced actuating rods 704 are mounted on the outside of the connecting rod 703. Rotation of the connecting rod 703 drives the actuating rods 704 to rotate. An arc-shaped screen plate 705 is installed inside the collecting chamber 5. During rotation, the actuating rods 704 continuously actuate the plastic particles falling onto the screen plate 705, allowing particles that meet the particle size requirements to pass through the screen plate 705, while larger particles remain on the screen plate 705, thus achieving the screening of plastic particles.

[0032] The screened plastic granules fall into the bottom of the collection chamber 5 for collection.

[0033] When it is necessary to discharge the plastic granules in the collection chamber 5, open the valve at the connection of the discharge pipe 8 on one side of the collection chamber 5, and the granules can be discharged through the discharge pipe 8.

[0034] If it is necessary to clean larger plastic particles on the screen plate 705, the sealed door on one side of the collection chamber 5 above the discharge pipe 8 can be opened to clean the large particles on the screen plate 705.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
