Description

Technical Field

[0001] This utility model relates to the field of disposable food plastic cup processing, specifically a screening device for polyester chip production. Background Technology

[0002] Polyester, especially PET (polyethylene terephthalate), is one of the commonly used materials for producing disposable food plastic cups. In the processing of disposable food plastic cups, polyester slitting and screening is a key step. Slitting refers to the process of cutting polyester material (such as polyester chips) into specific sizes and shapes, while screening refers to screening the slitting polyester material to remove unqualified parts so that subsequent processing can produce high-quality disposable food plastic cups.

[0003] In existing technologies, polyester is often used in the processing of disposable food plastic cups. During processing, the polyester is cut and then sieved to remove polyester particles that do not meet the size requirements. Generally, polyester is sieved by up-and-down or left-and-right vibration. However, relying solely on up-and-down or left-and-right vibration for sieving is not only inefficient and ineffective, but also because polyester itself has a certain degree of stickiness, causing some polyester to clump together. Up-and-down or left-and-right vibration alone cannot effectively break up these clumps, further reducing the effectiveness of polyester sieving. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, relying solely on up-and-down or left-and-right vibration to screen polyester is not only inefficient and ineffective, but also because polyester itself has a certain degree of stickiness, causing some polyester to adhere and clump together. Single up-and-down or left-and-right vibration cannot effectively break up the clumps of polyester, further reducing the effectiveness of polyester screening. This utility model proposes a screening device for polyester chip production.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a screening device for polyester chip production, including a processing box, a collection box slidably connected to the inner cavity of the processing box, a screening box arranged inside the processing box, a first fixing plate fixedly connected to the inner cavity of the processing box, and a screening mechanism arranged inside the processing box.

[0006] The screening mechanism includes a first spring, one end of which is fixedly connected to the top of a first fixed plate. A connecting plate is fixedly connected to one end of the first spring. A limiting rod is fixedly connected to the top of the first fixed plate. The surface of the limiting rod is slidably connected to the inner cavity of the connecting plate. An mounting plate is fixedly connected to the top of the connecting plate. A fixing rod is fixedly connected to one side of the mounting plate. A sliding block is slidably connected to the surface of the fixing rod. The top of the sliding block is fixedly connected to the bottom of the screening box. An auxiliary component is provided in the inner cavity of the processing box. A servo motor is fixedly connected to the inner cavity of the processing box. A drive rod is fixedly connected to the output end of the servo motor. A second cam is fixedly connected to the surface of the drive rod.

[0007] Preferably, the auxiliary component includes a fixing block, one side of which is fixedly connected to one side of a first fixing plate. A rotating rod is rotatably connected to the top of the fixing block. A worm gear and a first cam are fixedly connected to the surface of the rotating rod. A worm is fixedly connected to the surface of the drive rod. The teeth of the worm mesh with the teeth of the worm gear. A push plate is fixedly connected to the bottom of the screening box. A second spring is fixedly connected to one side of the mounting plate. One end of the second spring is fixedly connected to one side of a sliding block.

[0008] Preferably, a fixing ring block is fixedly connected to the surface of the limiting rod, and a rubber layer is fixedly connected to the top of the fixing ring block.

[0009] Preferably, a sliding plate is fixedly connected to the bottom of the screening box, and one side of the sliding plate is slidably connected to one side of the mounting plate.

[0010] Preferably, a second fixing plate is fixedly connected to one side of the mounting plate, and the surface of the second fixing plate is slidably connected to the inner cavity of the sliding plate.

[0011] Preferably, the top of the screening box is movably connected to a cover plate, and the inner cavity of the processing box is rotatably connected to a hinged door panel.

[0012] Preferably, the inner cavity of the screening box is fixedly connected to an inclined block, and the top of the fixed block is fixedly connected to a limiting ring block, the inner cavity of the limiting ring block being rotatably connected to the surface of the rotating rod.

[0013] The advantages of this utility model are:

[0014] This invention uses a servo motor to drive a drive rod to rotate, which in turn drives a second cam and a worm gear to rotate simultaneously. The second cam pushes the mounting plate and screening box upwards, while the worm gear, driven by a worm wheel, rotates horizontally, pushing the push plate and the first fixed plate. This achieves up-and-down and left-and-right vibration of the screening box, improving its screening efficiency. It not only increases screening effectiveness but also reduces clumps of polyester. This solves the problem that relying solely on up-and-down or left-and-right vibration for polyester screening is inefficient and ineffective. Polyester itself has a certain stickiness, causing some polyester to clump together, which cannot be effectively broken up by simple up-and-down or left-and-right vibration, further reducing the screening efficiency.

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a screening device for polyester chip production. (Refer to...) Figure 1 and Figure 5 A screening device for polyester chip production includes a processing box 1, a collection box 2 slidably connected to the inner cavity of the processing box 1, a screening box 3 disposed inside the processing box 1, a first fixing plate 4 fixedly connected to the inner cavity of the processing box 1, and a screening mechanism 5 disposed inside the processing box 1.

[0026] The screening mechanism 5 includes a first spring 501, one end of which is fixedly connected to the top of the first fixed plate 4. A connecting plate 503 is fixedly connected to one end of the first spring 501. A limiting rod 502 is fixedly connected to the top of the first fixed plate 4. The surface of the limiting rod 502 is slidably connected to the inner cavity of the connecting plate 503. An mounting plate 504 is fixedly connected to the top of the connecting plate 503. A fixing rod 505 is fixedly connected to one side of the mounting plate 504. A sliding block 506 is slidably connected to the surface of the fixing rod 505. The top of the sliding block 506 is fixedly connected to the bottom of the screening box 3. An auxiliary component 507 is provided in the inner cavity of the processing box 1. A servo motor 508 is fixedly connected to the inner cavity of the processing box 1. A drive rod 509 is fixedly connected to the output end of the servo motor 508. A second cam 510 is fixedly connected to the surface of the drive rod 509.

[0027] The screening box 3 inside the processing box 1 can screen polyester through the screening mechanism 5, while the collection box 2 can collect polyester that does not conform to the size after screening. The first fixing plate 4 can install and fix the first spring 501 and the limiting rod 502. The first spring 501 can connect to the connecting plate 503, and the limiting rod 502 can limit the up and down movement of the connecting plate 503. The connecting plate 503 can connect to the mounting plate 504, and the mounting plate 504 can connect to the sliding block 506 through the fixing rod 505. Because the sliding block 506 is fixedly connected to the screening box 3, the screening box 3 can move smoothly during use. The mounting plate 504 supports the material and ensures stable operation. When the connecting plate 503 moves up and down, it can also drive the sliding block 506 and the screening box 3 to move up and down together via the mounting plate 504, thereby achieving up and down vibration of the screening box 3 and realizing the vibration screening of polyester. The servo motor 508 can be connected to the second cam 510 via the drive rod 509. The second cam 510 can rotate when the servo motor 508 is running, and when it rotates, it can smoothly push the mounting plate 504. When the second cam 510 pushes the mounting plate 504 and releases the push on the mounting plate 504 by rotating, it can realize the continuous up and down reciprocating movement of the mounting plate 504.

[0028] Reference Figure 5 and Figure 6 The auxiliary component 507 includes a fixing block 5071, one side of which is fixedly connected to one side of the first fixing plate 4. A rotating rod 5072 is rotatably connected to the top of the fixing block 5071. A worm gear 5073 and a first cam 5075 are fixedly connected to the surface of the rotating rod 5072. A worm 5074 is fixedly connected to the surface of the drive rod 509. The teeth of the worm 5074 mesh with the teeth of the worm gear 5073. A push plate 5076 is fixedly connected to the bottom of the screening box 3. A second spring 5077 is fixedly connected to one side of the mounting plate 504. One end of the second spring 5077 is fixedly connected to one side of the sliding block 506. The first fixing plate 4 can install and connect the rotating rod 5072 through the fixing block 5071, while the rotating rod 5072 can connect the worm gear 5073 and the first cam 5075.

[0029] Furthermore, when the drive rod 509 rotates, it can smoothly achieve the rotation of the first cam 5075 through the meshing between the worm gear 5074 and the worm wheel 5073. When the first cam 5075 rotates, it can repeatedly push the push plate 5076, thereby enabling the push plate 5076 to drive the screening box 3 to move horizontally back and forth. This increases the vibration effect of the screening box 3 when screening polyester, improving the screening effect. Since the screening box 3 can move up and down and horizontally, some of the clumps of polyester can collide with the inner wall of the screening box 3 due to shaking, and thus be broken up by the collision. At the same time, the second spring 5077 can use its own elasticity to elastically reset the screening box 3 after the sliding block 506 and the screening box 3 have moved, so that the screening box 3 can effectively and continuously move horizontally back and forth.

[0030] Reference Figure 5 and Figure 6 A fixing ring block 7 is fixedly connected to the surface of the limiting rod 502, and a rubber layer 8 is fixedly connected to the top of the fixing ring block 7. The fixing ring block 7 makes it less likely that the connecting plate 503 will slide off the surface of the limiting rod 502 due to a large sliding distance when it slides on the surface of the limiting rod 502. The rubber layer 8 can reduce the impact force on the limiting rod 502 caused by the large downward movement distance when the screening mechanism 5 moves up and down, thereby reducing the possibility of damage to the limiting rod 502.

[0031] Reference Figure 4 and Figure 5 A sliding plate 12 is fixedly connected to the bottom of the screening box 3. One side of the sliding plate 12 is slidably connected to one side of the mounting plate 504. The setting of the sliding plate 12 not only increases the stability of the screening box 3 when moving horizontally, but also makes the screening box 3 connected to the side of the mounting plate 504 stable enough, and not prone to tilting or shaking.

[0032] Reference Figure 4 and Figure 6 A second fixing plate 9 is fixedly connected to one side of the mounting plate 504. The surface of the second fixing plate 9 is slidably connected to the inner cavity of the sliding plate 12. The second fixing plate 9 can further restrict the horizontal reciprocating movement of the screening box 3 through its connection with the sliding plate 12, making it more stable during movement and less prone to shaking or deviation.

[0033] Reference Figure 1 and Figure 2The top of the screening box 3 is movably connected to a cover plate 10, and the inner cavity of the processing box 1 is rotatably connected to a hinged door plate 11. The cover plate 10 is designed so that when the screening box 3 vibrates up and down, the polyester inside the screening box 3 is not easily pushed out of the screening box 3. The hinged door plate 11 makes it easy for the staff to take the collection box 2 out of the processing box 1 or to place the collection box 2 into the processing box 1.

[0034] Reference Figure 2 and Figure 6 An inclined block 13 is fixedly connected to the inner cavity of the screening box 3, and a limiting ring block 6 is fixedly connected to the top of the fixed block 5071. The inner cavity of the limiting ring block 6 is rotatably connected to the surface of the rotating rod 5072. With the setting of the inclined block 13, the polyester inside the screening box 3 can be smoothly located on both sides inside the screening box 3, so that the polyester can be screened more smoothly. The limiting ring block 6 can increase the stability of the connection between the rotating rod 5072 and the fixed block 5071, so that the rotating rod 5072 is not easy to shake or tilt during use.

[0035] Working Principle: When using this device, the operator can add the polyester that needs to be screened and sliced ​​into the screening box 3. After adding, the cover plate 10 is connected to the top of the screening box 3. Then, the servo motor 508 can be started. When the servo motor 508 is operating, it can smoothly drive the drive rod 509 to rotate. The rotation of the drive rod 509 can drive the second cam 510 and the worm gear 5074 to rotate together. When the second cam 510 rotates, it can smoothly push the mounting plate 504, so that the mounting plate 504 can move the screening box 3 upward through the connection between the fixed rod 505 and the sliding block 506. When the second cam 510 rotates to a certain angle, it will release the push on the mounting plate 504. At this time, the mounting plate 504 can be reset by its own weight and the elasticity of the first spring 501. The continuous rotation of the second cam 510 can realize the continuous up and down reciprocating movement of the screening box 3, realizing the vibration of the screening box 3.

[0036] Meanwhile, the rotation of the worm gear 5074 can smoothly drive the rotating rod 5072 and the first cam 5075 to rotate through the worm wheel 5073. When the first cam 5075 rotates, it can push the push plate 5076, causing the screening box 3 to move. After the first cam 5075 rotates to a certain angle, it can release the push of the push plate 5076, allowing the screening box 3 to be reset by the elasticity of the second spring 5077, thereby realizing the horizontal reciprocating movement of the screening box 3 and improving the vibration effect of the screening box 3. The polyester screened by the vibration of the screening box 3 will fall into the inside of the collection box 2 for collection and processing by the staff.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
