Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic particle screening machine. Background Art

[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. Microplastics can harm human health. Their deformation resistance is medium, between that of fibers and rubber. They are composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. When processing and producing plastic products, plastic particles are used as raw materials for hot melting or other processing, and then the plastic particles are made into plastic products. Before the production of plastic products, the plastic particles need to be screened to remove particles that do not meet the particle size requirements.

[0003] The existing plastic particle screening device screens the plastic particles by shaking them left and right or back and forth. However, the temperature of the plastic particles extruded after melting is relatively high, so when the plastic particles are shaken left and right or back and forth, the plastic particles are easily adhered together to form lumps, making it impossible to screen and discharge the materials.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 5 The utility model provides a technical solution: a plastic particle screening machine, including a screening box 1 and a screening mechanism 6, the top of the screening box 1 is connected with a feeding port 2, and both sides of the screening box 1 are provided with discharge ports 3, and the inner wall of the screening box 1 is installed with a mounting shaft 4, and a screening plate 5 is rotatably installed on the surface of the mounting shaft 4, which can facilitate the user to add materials from the feeding port 2, so that the materials are sprinkled onto the screening plate 5 on the surface of the mounting shaft 4, and the screening mechanism 6 can squeeze the screening plate 5 when rotating, so that the screening plate 5 is shaken up and down, so that the screening plate 5 is shaken to screen the materials.

[0030] Reference Figure 1-Figure 5In a preferred embodiment, a screening mechanism 6 is provided, the screening mechanism 6 includes a rotating rod 61, a mounting sleeve 62, an extrusion block 63 and a fixed block 64. The rotating rod 61 is provided with two groups. The rotating rod 61 is rotatably installed on the inner wall of the screening box 1. The back of the rotating rod 61 penetrates the outer side of the screening box 1. The mounting sleeve 62 is fixedly installed on the surface of the rotating rod 61. The extrusion block 63 is installed on the surface of the mounting sleeve 62. The surface of the extrusion block 63 is arranged in an arc shape. The fixed block 64 is installed at the bottom of the screening plate 5. The fixed block 64 is located at the top of the rotating rod 61, so that the rotating rod 61 can install the mounting sleeve 62 after installation, so as to facilitate the installation of the extrusion block 63 on the mounting sleeve 62. When the rotating rod 61 drives the mounting sleeve 62 to rotate, it drives the extrusion block 63 to squeeze the fixed block 64, so that the screening plate 5 shakes up and down to screen the material, and the unscreened material can be discharged from the discharge port 3.

[0031] At the same time, support plates 20 are fixedly installed on both sides of the inner wall of the screening box 1, and a blocking plate 21 is fixedly installed on the top of the screening plate 5, so that the support plate 20 can support the screening plate 5 after installation, so that the screening plate 5 can shake to screen the material. The installed blocking plate 21 can prevent the material from spilling, and a stretching block is installed on the inner wall of the screening box 1 at the top of the installation shaft 4. The stretching block is made of elastic material, and a collecting box 22 is slidably installed on the bottom of the inner wall of the screening box 1. The collecting box 22 is located at the bottom of the screening plate 5, so that after the screening plate 5 screens the material, small particles of material can fall into the collecting box 22 for collection.

[0032] Reference Figure 1-Figure 4 In a preferred embodiment, a transmission wheel 7 is fixedly installed on the back of the rotating rod 61, a mounting seat 8 is fixedly installed on the back of the screening box 1, a motor 9 is fixedly installed on the top of the mounting seat 8, the output end of the motor 9 is fixedly connected to the transmission wheel 7, and a first transmission belt 10 is sleeved inside the belt groove on the surface of the transmission wheel 7, so that the motor 9 can be installed after the mounting seat 8 is installed, so that the motor 9 drives the rotating rod 61 to rotate through the transmission wheel 7 and the first transmission belt 10 after starting, wherein the transmission wheel 7 is a double-groove transmission wheel 7.

[0033] Reference Figure 1-Figure 4In a preferred embodiment, a screw rod 11 is rotatably installed on the inner wall of the screening box 1, and the screw rod 11 is provided with two groups. A screw sleeve 12 is installed on the surface of the screw rod 11, and a mounting block 13 is installed at the bottom of the screw sleeve 12. A dispersion rod 14 is fixedly installed at the bottom of the mounting block 13, and the dispersion rod 14 is provided with several groups. The front and rear sides of the bottom of the mounting block 13 are plugged with mounting plates 15, which can make the screw rod 11 drive the screw sleeve 12 to move when rotating, so that the screw sleeve 12 drives the mounting block 13 and the dispersion rod 14 to move, so that the dispersion rod 14 moves to disperse the materials, and the dispersion rod 14 is made of elastic material, wherein a limiting plate 16 is fixedly installed on the inner wall of the screening box 1, and a limiting block 17 is fixedly installed on the surface of the screw sleeve 12, and the limiting block 17 is slidably connected with the limiting plate 16, so that the limiting plate 16 can be slidably matched with the limiting plate 16 after installation, which is convenient for limiting the screw sleeve 12, so that the screw sleeve 12 can move stably.

[0034] At the same time, the back side of the screw rod 11 penetrates to the back side of the screening box 1, and a driven wheel 18 is fixedly mounted on the surface of the screw rod 11. A second transmission belt 19 is wound around the surface of the driven wheel 18. The second transmission belt 19 is sleeved inside the belt grooves on the surfaces of the driving wheel 7 and the driven wheel 18, so that the driving wheel 7 can drive the driven wheel 18 to rotate through the second transmission belt 19 when rotating, so that the driven wheel 18 can drive the screw rod 11 to rotate.

[0035] Specifically, the working process or working principle of the plastic particle screening machine is as follows: when in use, the user starts the motor 9 and adds the material into the screening box 1 from the feeding port 2, so that the material falls onto the upper screening plate 5. After the motor 9 is started, the motor 9 drives the two sets of transmission wheels 7 to rotate at the same time through the first transmission belt 10, and when the two sets of transmission wheels 7 rotate, the transmission wheel 7 can drive the driven wheel 18 to rotate through the second transmission belt 19, and when the transmission wheel 7 rotates, it will drive the rotating rod 61 to rotate, so that the rotating rod 61 drives the extrusion block 63 to rotate through the mounting sleeve 62. Squeezing the fixed block 64 can cause the screening plate 5 to tilt and shake, so as to screen the material, discharge large particles of material from the discharge port 3, and allow small particles of material to fall onto the screening plate 5 on the lower layer for screening or directly fall into the collecting box 22. When the driven wheel 18 rotates, it will drive the screw rod 11 to rotate, so that the screw rod 11 can move with the mounting block 13 through the screw sleeve 12, so that the mounting block 13 can drive the dispersion rod 14 to move and disperse the material, thereby preventing the material from piling up and sliding down together, and can disperse the material to prevent the material from sticking together, thereby improving the screening effect and screening efficiency of the material.

[0036] It should be noted that the motor 9 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
