Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, and in particular to a plastic particle screening device. Background Technology

[0002] Plastic pellets, also known as plastic granules, are small granular substances formed after plastic processing. They are the basic raw material for the production of plastic products. Plastic pellets are made from raw materials such as petroleum and natural gas through polymerization reactions to produce high molecular compounds. They are then processed through cutting, granulation, and other processes to produce particles with a particle size of 0.5-5 mm. When screening plastic pellets, a plastic pellet screening device is needed. The plastic pellet screening device is used to separate plastic pellets of different particle sizes. Its core function is to remove impurities and screen out particles that meet the specifications, ensuring the stability of subsequent production.

[0003] To address this, the specification of patent CN218053477U discloses a PVC plastic particle screening device, including a box body. A door is hinged to the front of the box body, and a feed hopper is fixedly installed on the top. An installation frame is located inside the box body, with a vibration motor at the bottom. An installation groove is formed inside the installation frame, and a screening frame is installed inside the groove to accelerate screening. A fixing frame is welded to the upper surface of the installation frame, and a sliding plate groove is formed on the side of the fixing frame near the screening frame. Sliding plates are welded to the left and right sides of the screening frame, and the sliding plate groove is slidably connected to the sliding plates. A limiting groove is formed on the side of the sliding plates. A limiting rod is inserted through the fixing frame, and the limiting groove engages with the limiting rod. A guide plate is fixedly installed at the bottom of the inner wall of the box body, and a discharge pipe is provided at the bottom of the box body. The device allows for easy and quick assembly and disassembly of the screening frame without the need for tools.

[0004] The aforementioned PVC plastic particle screening device aims to make it more convenient and faster for workers to assemble and disassemble the screening frame without the need for tools. However, when the box receives materials, it may shift, causing materials to leak out. Utility Model Content

[0005] The purpose of this invention is to provide a plastic particle screening device to solve the problem that existing plastic particle screening devices are difficult to limit the position of the box.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic particle screening device, including a base;

[0007] The base has a housing at its top, an outer shell at its top, a rotating shaft on one side of the outer shell, and a cover plate at its top.

[0008] An inlet is installed on one side of the top of the outer shell, a screen is installed at the bottom of the outer shell, a box is installed at the bottom of the shell, and a limit structure is installed on both sides of the box.

[0009] The limiting structure includes an installation plate installed at the bottom of the housing, a guide rod installed at the top of one side of the installation plate, a limiting plate installed on one side of the guide rod, and a first spring installed on one side of the limiting plate.

[0010] In use, the servo motor first drives the rotating shaft to rotate, allowing plastic particles to be loaded into the outer shell through the inlet. The rotation of the outlet shaft moves the plastic particles inside the shell, allowing them to be filtered through the screen. The plastic particles are stirred and tumbled during movement, improving the screening effect. The screened plastic particles are guided by the inclined plate and fall into the box for storage, while the unscreened plastic particles are discharged through the outlet on one side of the outer shell.

[0011] Furthermore, inclined plates are installed on both sides of the top of the shell, and the inclined plates are symmetrically distributed about the central axis of the shell. The inclined plates can guide the sieved particles.

[0012] Furthermore, the bottom end of the limiting plate is provided with a slider, and the top end of the base is provided with a sliding groove. The limiting plate and the base constitute a sliding structure, and the limiting plate can slide on the base.

[0013] Furthermore, the first spring is helical in shape, and the first spring and the limiting plate form an elastic connection, and the first spring is elastic.

[0014] Furthermore, a discharge mechanism is installed inside the outer casing. The discharge mechanism includes a servo motor mounted on one side of the outer casing, a rotating shaft mounted on one side of the servo motor, and a discharge shaft located on the outer side of the rotating shaft. The discharge mechanism can drive the particles to move.

[0015] Furthermore, a positioning structure is installed at the top of the outer shell, and the positioning structure includes a fixing plate installed at the top of the outer shell, a second spring installed at the bottom of the fixing plate, and a buckle installed at the bottom of the second spring. The positioning structure can fix the cover plate.

[0016] Furthermore, a locking block is provided at the top of the cover plate, and a locking groove is provided on one side of the outer shell. The cover plate and the outer shell form a locking structure, which facilitates disassembly.

[0017] The plastic particle screening device provided by this utility model has the following advantages: during use, the cover plate can be fixed by the positioning structure to prevent the cover plate from falling off; the box body can be limited by the limiting structure to prevent the box body from shifting; and the material can be moved by the discharge mechanism to make the material screening effect better.

[0018] A box is installed at the top of the base. The box can be placed on the top of the base. The mounting plate and the limiting plate are connected by a first spring and a guide rod. The elasticity of the first spring will drive the limiting plate to move. The limiting plate can clamp the box and limit the box. The limiting plate can limit the box to the middle position at the top of the base. This can prevent the box from shifting and also allow the box to better receive materials. The guide rod can extend and retract. The guide rod can prevent the limiting plate from shifting. In this way, the plastic particle screening device can easily limit the box.

[0019] A servo motor is installed on one side of the outer casing. The servo motor drives the rotating shaft to rotate, which in turn drives the discharge shaft to rotate. The discharge shaft is spiral-shaped and allows material to be loaded into the outer casing through the inlet. The rotation of the discharge shaft causes the material inside the outer casing to move. As the material moves inside the outer casing, it can be filtered through the screen. The material is stirred and tumbled during movement, which improves the screening effect. This achieves the purpose of the plastic particle screening device to enhance the screening effect. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 One embodiment of this utility model is a plastic particle screening device, which includes a base 2.

[0028] The top of the base 2 is fitted with a housing 1, and inclined plates 11 are fitted on both sides of the top of the housing 1. The inclined plates 11 are symmetrically distributed about the central axis of the housing 1.

[0029] The top of the housing 1 is fitted with an outer shell 5. Inside the outer shell 5 is a discharge mechanism 6. The discharge mechanism 6 includes a servo motor 601 mounted on one side of the outer shell 5, a rotating shaft 602 mounted on one side of the servo motor 601, and a discharge shaft 603 disposed on the outer side of the rotating shaft 602.

[0030] See attached document Figure 2 and attached Figure 4 As shown, the servo motor 601 drives the rotating shaft 602 to rotate, which in turn drives the discharge shaft 603 to rotate. The discharge shaft 603 is spiral in shape and can load plastic particles into the housing 5 through the inlet 7. The rotation of the discharge shaft 603 can move the plastic particles inside the housing 5. When the plastic particles move inside the housing 5, they can be filtered through the screen 8. The plastic particles are stirred and rolled during movement, which improves the screening effect. The screened plastic particles can be guided by the inclined plate 11 and fall into the box 4 for storage. The plastic particles that are not screened can be discharged through the outlet on one side of the housing 5.

[0031] A positioning structure 9 is installed at the top of the outer shell 5, and the positioning structure 9 includes a fixing plate 901 installed at the top of the outer shell 5, a second spring 902 installed at the bottom of the fixing plate 901, and a buckle 903 installed at the bottom of the second spring 902.

[0032] See attached document Figure 1-3 As shown, the cover plate 10 can be locked onto one side of the outer shell 5 to close the outer shell 5. When using the device, the cover plate 10 can rotate along the rotating shaft 12. The rotation of the cover plate 10 forms an inclined surface, which can guide the outgoing particles. When the cover plate 10 is closed, the buckle 903 is connected to the fixing plate 901 through the second spring 902. The elasticity of the second spring 902 will cause the buckle 903 to lock the cover plate 10, preventing the cover plate 10 from falling off. When it is necessary to open the cover, pull up the buckle 903 so that the buckle 903 no longer locks the cover plate 10, and the cover plate 10 can be opened.

[0033] A rotating shaft 12 is installed on one side of the outer casing 5, and a cover plate 10 is installed on the top of the rotating shaft 12. A locking block is provided on the top of the cover plate 10, and a locking groove is provided on one side of the outer casing 5. The cover plate 10 and the outer casing 5 form a locking structure.

[0034] An inlet 7 is installed on one side of the top of the outer shell 5, a screen 8 is installed at the bottom of the outer shell 5, a box 4 is installed at the bottom of the shell 1, and a limit structure 3 is installed on both sides of the box 4.

[0035] The limiting structure 3 includes an installation plate 301 installed at the bottom of the housing 1, a guide rod 303 installed at the top of one side of the installation plate 301, and a limiting plate 302 installed on one side of the guide rod 303. A slider is provided at the bottom of the limiting plate 302, and a sliding groove is provided at the top of the base 2. The limiting plate 302 and the base 2 constitute a sliding structure.

[0036] A first spring 304 is installed on one side of the limiting plate 302. The first spring 304 is spiral in shape, and the first spring 304 and the limiting plate 302 form an elastic connection.

[0037] See attached document Figure 1-2 and attached Figure 5 As shown, the box 4 can be placed on the top of the base 2. The mounting plate 301 and the limiting plate 302 are connected by a first spring 304 and a guide rod 303. The first spring 304 is elastic, and the elasticity of the first spring 304 will drive the limiting plate 302 to move. The limiting plate 302 can clamp the box 4 and limit the box 4. Since the first spring 304 and the limiting plate 302 are symmetrically distributed about the central axis of the base 2, the limiting plate 302 can limit the box 4 to the middle position at the top of the base 2. This can prevent the box 4 from shifting and also allow the box 4 to receive materials better. The guide rod 303 can extend and retract, and the guide rod 303 can prevent the limiting plate 302 from shifting.

[0038] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
