Description

Technical Field

[0001] This utility model relates to the field of recycled plastics technology, and in particular to a device for producing recycled plastic pellets. Background Technology

[0002] In the production process of recycled plastic pellets, the melt extrusion pelletizing stage uses a pelletizer to cut the cooled plastic strips into pellets. However, the pellets are often of different sizes and need to be screened. However, the existing screening methods have obvious drawbacks.

[0003] The process typically involves a single sieve combined with manual screening. From an efficiency perspective, manual intervention makes the screening process slow and difficult to match with automated production processes. In the large-scale production of recycled plastic pellets, the low efficiency of manual operation becomes a bottleneck in the entire production process, slowing down production progress, increasing time costs, and failing to meet the high efficiency requirements of modern production.

[0004] From a practical application perspective, individual screens are prone to clogging. Recycled plastic granules may contain impurities, or the granules may have high moisture content or irregular shapes due to various factors during production. These conditions can cause granules to get stuck in the screen holes when passing through a single screen, resulting in screen blockage. Once the screen is blocked, frequent shutdowns for cleaning are required. This not only interrupts the normal production process and reduces production efficiency, but also exacerbates screen wear due to frequent disassembly and installation. After the screen wears down, the size and shape of its screen holes will change, which will affect the accuracy of particle size classification, resulting in uneven particle size after screening and failing to guarantee product quality.

[0005] To address this issue, a recycled plastic pellet production device is proposed to solve the problems existing in the current technology. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems by providing a recycled plastic pellet production device. This invention utilizes a connecting assembly between two limiting boxes. Driven by a motor and aided by the elastic force of a limiting spring, the limiting boxes reciprocate within corresponding square slots, thereby causing the sieve plate and receiving plate to reciprocate relative to each other. Compared to manual screening using a single sieve, this achieves automated continuous screening without frequent manual intervention, significantly improving screening efficiency. To achieve the aforementioned objective, the technical solution adopted by this invention is as follows:

[0007] According to one aspect of this utility model, a recycled plastic pellet production device is provided, including a housing, a base at the bottom of the housing, a support seat at the top of the base, two square slots symmetrically opened on the support seat, and a through slot at the top of each square slot, a first limiting box and a second limiting box respectively provided in the two square slots, a drive motor inside the first limiting box, a limiting spring in each square slot, and each limiting spring connected to the corresponding first limiting box and second limiting box respectively, a screen plate and a receiving plate vertically parallel to each other at the top of the housing, with the receiving plate located at the lower end of the screen plate, a connecting plate at the top of the first limiting box, the other end of the connecting plate being connected to the receiving plate, a Y-shaped rod at the top of the second limiting box, both ends of the other side of the Y-shaped rod being connected to the screen plate, and a connecting assembly between the first limiting box and the second limiting box.

[0008] Preferably, the first limiting box is provided with a rotating rod, and the rotating rod is connected to the output shaft of the drive motor. The rotating rod is provided with a cam plate, and the other end of the cam plate is provided with a connecting rod. The second limiting box is provided with a connecting rod, and a connecting rod is provided between the first connecting rod and the second connecting rod.

[0009] Preferably, the sieve plate and the receiving plate are parallel to each other, and the sieve plate and the receiving plate are inclined downwards at an angle of 2°-5°.

[0010] Preferably, both the sieve plate and the receiving plate outlet are provided with intercepting bars, and the cross-sectional shape of the intercepting bars is arc-shaped.

[0011] Preferably, the receiving plate has a groove at its lower end near the Y-shaped rod, and a slider is provided in the groove. The upper end of the Y-shaped rod has a sliding rod connected to the slider. The receiving plate has symmetrically formed sliding grooves on both sides near the connecting plate, and each sliding groove has a sliding block. Each sliding block has a U-shaped rod, and each U-shaped rod is connected to the sieve plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] The present invention discloses a recycled plastic pellet production device. By providing a connecting component between limiting box one and limiting box two, the limiting box one and limiting box two are driven by a drive motor and the elastic force of the limiting spring to move back and forth in the corresponding square grooves. This, in turn, drives the sieve plate and the receiving plate to move back and forth relative to each other. Compared with manual assistance in screening a single sieve, this device achieves automated continuous screening without frequent manual intervention, greatly improving screening efficiency.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0019] Please see Figures 1 to 3 This utility model provides a device for producing recycled plastic pellets, the technical solution of which is as follows:

[0020] The device includes a housing 1, a base 2 at the bottom of the housing 1, a support 3 at the top of the base 2, two square slots 4 symmetrically formed on the support 3, and a through slot 5 at the top of each square slot 4. A first limiting box 6 and a second limiting box 7 are respectively provided in the two square slots 4. A drive motor is installed inside the first limiting box 6. A limiting spring 8 is installed in each square slot 4, and each limiting spring 8 is connected to the corresponding first limiting box 6 and second limiting box 7. A screen plate 9 and a receiving plate 10 are vertically parallel on the top of the housing 1, with the receiving plate 10 located below the screen plate 9. A connecting plate 11 is provided on the top of the first limiting box 6, and the other end of the connecting plate 11 is connected to the receiving plate 10. A Y-shaped rod 12 is provided on the top of the second limiting box 7, and both ends of the other side of the Y-shaped rod 12 are connected to the screen plate 9. A connecting assembly is provided between the first limiting box 6 and the second limiting box 7.

[0021] Plastic granules fall from the top of the casing 1 onto the screen. At this time, the drive motor starts and, through the connecting component and the limiting spring 8, drives the limiting box 6 and the limiting box 7 to reciprocate within the corresponding square groove 4. Then, through the connecting plate 11 and the Y-shaped rod 12, the screen plate 9 and the receiving plate 10 reciprocate. The screen plate 9 and the receiving plate 10 reciprocate relative to each other. The plastic granules are subjected to continuous vibration of the screen. Compared with manual screening of a single screen, this achieves automated continuous screening without frequent manual intervention, which greatly improves screening efficiency.

[0022] Conveyor belts are connected to the screen and the outlet of the receiving plate 10 respectively. Plastic granules that meet the standards after being screened by the screen plate 9 are transported to the next process by the conveyor belt at the outlet of the receiving plate 10 for quality control and packaging. Meanwhile, unqualified plastic granules that have passed through the screen fall onto the conveyor belt at the outlet of the screen plate 9 and are transported back to the previous process for remelting, thus avoiding material waste.

[0023] The first limiting box 6 is provided with a rotating rod 13, which is connected to the output shaft of the drive motor. The rotating rod 13 is provided with a cam plate 14, and the other end of the cam plate 14 is provided with a connecting rod 15. The second limiting box 7 is provided with a connecting rod 16, and a connecting rod 17 is provided between the connecting rod 15 and the connecting rod 16.

[0024] The drive motor drives the cam plate 14 to rotate. The cam plate 14 forms a connecting rod 17 mechanism through connecting rod 15, connecting rod 17 and connecting rod 16. The limiting box 1 6 and limiting box 2 7 restrict each other. With the help of the elastic force of the limiting spring 8, they drive each other to move back and forth in the corresponding square groove 4, thereby driving the screen plate 9 and the receiving plate 10 to move back and forth relative to each other, improving the screening efficiency.

[0025] The sieve plate 9 and the receiving plate 10 are parallel to each other, and the sieve plate 9 and the receiving plate 10 are inclined downwards at an angle of 2°-5°.

[0026] Utilizing gravity, plastic granules can move more smoothly on the sieve plate 9, flowing downwards on their own without additional power, which helps improve the efficiency of granule screening and allows granules to pass through the sieve plate 9 more quickly to complete the screening process. A suitable tilt angle can prevent plastic granules from accumulating locally on the sieve plate 9. If the sieve plate 9 is placed horizontally, granules tend to gather in certain areas, affecting the screening effect. However, the tilt setting allows the granules to slide downwards continuously and be evenly distributed on the sieve plate 9, ensuring a stable screening process.

[0027] Both the sieve plate 9 and the receiving plate 10 are equipped with intercepting bars 18 at their outlets, and the cross-sectional shape of the intercepting bars 18 is arc-shaped. The arc-shaped intercepting bars 18, located at the outlets of the sieve plate 9 and the receiving plate 10, effectively prevent plastic particles from sliding down directly and quickly. When particles move to the outlet on the sieve plate 9 and the receiving plate 10, they may slide out quickly due to inertia or the action of the inclined plate. The arc-shaped intercepting bars 18 can change the trajectory of the particles, allowing them to stay on the sieve plate 9 and the receiving plate 10 for longer, thus improving screening accuracy.

[0028] The receiving plate 10 has a groove 19 at its lower end near the Y-shaped rod 12, and a slider 20 is provided in the groove 19. The upper end of the Y-shaped rod 12 has a slider 21, and the slider 21 is connected to the slider 20. The receiving plate 10 has symmetrically provided sliding grooves 22 on both sides near the connecting plate 11, and each sliding groove 22 has a sliding block 23. Each sliding block 23 has a U-shaped rod 24, and each U-shaped rod 24 is connected to the sieve plate 9.

[0029] By connecting the slide groove 19, slider 20, slide rod 21, slide groove 22, slide block 23, and U-shaped rod, a stable linkage structure is constructed between the screen plate 9 and the receiving plate 10. During the operation of the equipment, it can ensure that the screen plate 9 and the receiving plate 10 move in a coordinated manner in a predetermined way, ensuring the consistency and stability of the screening action and effectively improving the screening effect.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
