Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically a particle screening device for a granulator. Background Technology

[0002] In the production of polyamide thermal insulation strips, the raw materials are often heated and melted before being formed into granules for subsequent processing. After the polyamide granules are formed using a granulator, they need to be screened to separate unqualified polyamide granules from qualified ones.

[0003] Existing granulator particle screening devices mostly use screens placed on the inside to screen polyamide particles. During screening, unqualified particles accumulate on the top of the screen, which is not only difficult to remove, but also affects the screening stability of the device. Therefore, a granulator particle screening device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A granulator particle screening device of this utility model includes a screening box. A motor is fixedly connected to the outside of the screening box, and a screen is fixedly connected to the output end of the motor. A rotating groove is formed on the surface of the screening box, and the rotating groove and the screen are rotatably connected. A first guide plate is fixedly connected to the inside of the screening box, and the first guide plate works in conjunction with the screen. A second guide plate is fixedly connected to the inside of the screening box. A through groove is formed on the surface of the screening box, and one side of the through groove and the second guide plate... This process involves setting up a screening box, motor, screen, rotating trough, first guide plate, second guide plate, and through trough. During use, polyamide granules are poured into one side of the through trough, allowing them to fall onto the screen along the first guide plate. The screen filters the granules and blocks any that are not up to standard. After screening, the motor drives the screen to rotate, causing the unqualified granules to rotate out of the rotating trough and fall, thus removing them from the screening box for subsequent recycling and processing, improving the ease of use of the device.

[0006] Preferably, a collection box is fixedly connected to the outside of the screening box, and a crushing roller assembly is provided inside the collection box. By setting up the collection box and the crushing roller assembly, after the unqualified polyamide particles fall out from the inside of the screening box, they can be collected by the collection box, and when the polyamide particles fall, they can be further crushed by the crushing roller assembly to reduce their size, thereby facilitating their passage through screening and improving the convenience of using the device.

[0007] Preferably, a support box is fixedly connected to the outside of the collection box, and a lifting belt assembly is provided on the inside of the support box. Discharge grooves are provided on both the surface of the collection box and the surface of the support box. A guide frame is fixedly connected to the outside of one side of the discharge groove, and the through groove and the guide frame work together on the other side. In this step, by setting up the support box, lifting belt assembly, discharge groove and guide frame, after the unqualified polyamide particles are further crushed by the crushing roller assembly, they can fall into the inside of the support box through the discharge groove of the collection box. The lifting belt assembly lifts the crushed polyamide particles, so that the crushed polyamide particles can rise to the discharge groove on the surface of the support box and move along the inclined surface inside the guide frame until they fall into the inside of the through groove again. Then, the crushed polyamide particles can be screened again by the screen, which improves the convenience of the device recycling.

[0008] Preferably, a baffle is slidably connected to the inner side of the screening box, and the baffle works in conjunction with the rotating trough. This step, by setting the baffle, allows the screen to move to block the lower half of the rotating trough when the screen does not need to rotate, thereby making it difficult for the polyamide particles passing through the screen and rotating trough to fall out of the screening box, thus improving the stability of the device.

[0009] Preferably, a magnetic plate is fixedly connected to the outside of the baffle, and the magnetic plate is used in conjunction with the screening box. By setting the magnetic plate, when the baffle moves to block the lower half of the rotating trough, it can be attracted to the outside of the screening box by the magnetic plate, which facilitates further restriction and fixation of the baffle position and improves the stability of the device.

[0010] Preferably, a fixing plate is fixedly connected to the outside of the screening box, and a fan is fixedly connected to the outside of the fixing plate. By setting up the fixing plate and the fan, when the screen drives the unqualified polyamide particles to rotate to the upper side of the collection box, the fan can drive the air to flow downward, thereby facilitating the separation of the unqualified polyamide particles from the screen and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a screening box, motor, screen, rotating trough, first guide plate, second guide plate and through trough, allows polyamide granules to be poured into one side of the through trough during use. The polyamide granules fall onto the upper part of the screen along the first guide plate. The screen screens the polyamide granules and blocks unqualified polyamide granules. After screening, the motor drives the screen to rotate, which drives the unqualified polyamide granules out of the rotating trough and fall off, thereby removing them from the screening box for subsequent recycling and processing, thus improving the convenience of the device.

[0013] 2. By setting up a collection box and a crushing roller assembly, the present invention can collect unqualified polyamide particles after they fall out from the inside of the screening box, and further crush them by the crushing roller assembly as they fall, so as to reduce their size and facilitate their passage through screening, thereby improving the convenience of the device.

[0021] 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.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a granulator particle screening device includes a screening box 1. A motor 2 is fixedly connected to the outside of the screening box 1, and a screen 3 is fixedly connected to the output end of the motor 2. A rotating groove 4 is formed on the surface of the screening box 1, and the rotating groove 4 and the screen 3 are rotatably connected. A first guide plate 5 is fixedly connected to the inside of the screening box 1, and the first guide plate 5 and the screen 3 work together. A second guide plate 6 is fixedly connected to the inside of the screening box 1. A through groove 7 is formed on the surface of the screening box 1, and one side of the through groove 7 works together with the second guide plate 6. This step involves setting the screen... The device consists of a screening box 1, a motor 2, a screen 3, a rotating trough 4, a first guide plate 5, a second guide plate 6, and a through trough 7. In use, polyamide granules are poured into the through trough 7 on one side, causing them to fall onto the screen 3 along the first guide plate 5. The screen 3 filters the polyamide granules and blocks any unqualified granules. After screening, the motor 2 drives the screen 3 to rotate, causing the unqualified polyamide granules to rotate out of the rotating trough 4 and fall, thus removing them from the screening box 1 for subsequent recycling and processing, improving the ease of use of the device.

[0024] Furthermore, such as Figure 1 and Figure 4 As shown, a collection box 8 is fixedly connected to the outside of the screening box 1, and a crushing roller assembly 9 is provided inside the collection box 8. By setting up the collection box 8 and the crushing roller assembly 9, after the unqualified polyamide particles fall out from the inside of the screening box 1, they can be collected by the collection box 8, and when the polyamide particles fall, they can be further crushed by the crushing roller assembly 9 to reduce their size, thereby facilitating their passage through the screening and improving the convenience of using the device.

[0025] Furthermore, such as Figure 1 and Figure 5 As shown, a support box 10 is fixedly connected to the outside of the collection box 8, and a lifting belt assembly 11 is provided inside the support box 10. Discharge grooves 12 are provided on the surface of both the collection box 8 and the support box 10. A guide frame 13 is fixedly connected to the outside of one side of the discharge groove 12, and the through groove 7 on the other side works in conjunction with the guide frame 13. In this step, by setting up the support box 10, lifting belt assembly 11, discharge groove 12 and guide frame 13, after the unqualified polyamide particles are further crushed by the crushing roller assembly 9, they can fall into the inside of the support box 10 through the discharge groove 12 of the collection box 8. The lifting belt assembly 11 lifts the crushed polyamide particles, so that the crushed polyamide particles can rise to the discharge groove 12 on the surface of the support box 10 and move along the inclined surface inside the guide frame 13 until they fall into the inside of the through groove 7 again. Thus, the crushed polyamide particles can be screened again by the screen 3, which improves the convenience of the device for recycling.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, a baffle 14 is slidably connected to the inner side of the screening box 1. The baffle 14 and the rotating trough 4 are used in conjunction. By setting the baffle 14, when the screen 3 does not need to rotate, the baffle 14 can be moved to block the lower half of the rotating trough 4, thereby making it difficult for the polyamide particles passing through the screen 3 and the rotating trough 4 to fall out of the screening box 1, thus improving the stability of the device.

[0027] Furthermore, such as Figure 2 As shown, a magnetic plate 15 is fixedly connected to the outside of the baffle 14. The magnetic plate 15 is used in conjunction with the screening box 1. By setting the magnetic plate 15, when the baffle 14 moves to block the lower half of the rotating trough 4, it can be attracted to the outside of the screening box 1 by the magnetic plate 15, which facilitates further restriction and fixation of the position of the baffle 14 and improves the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a fixing plate 16 is fixedly connected to the outside of the screening box 1, and a fan 17 is fixedly connected to the outside of the fixing plate 16. By setting the fixing plate 16 and the fan 17, when the screen 3 drives the unqualified polyamide particles to rotate to the upper side of the collection box 8, the fan 17 can drive the air to flow downward, thereby facilitating the separation of the unqualified polyamide particles from the screen 3 and improving the stability of the device.

[0029] Working principle: During use, polyamide granules are poured into the through-slot 7 on one side, allowing them to fall onto the screen 3 along the first guide plate 5. The screen 3 filters the polyamide granules and blocks any unqualified granules. After sieving, the motor 2 drives the screen 3 to rotate, causing the unqualified polyamide granules to rotate out of the trough 4 and fall into the collection box 8 for collection. As the polyamide granules fall, they are further pulverized by the crushing roller assembly 9 to reduce their size. Then, they fall into the support box 10 through the discharge trough 12. The lifting belt assembly 11 lifts the pulverized polyamide granules, allowing them to rise to the discharge trough 12 on the surface of the support box 10 and move along the inclined surface inside the guide frame 13 until they fall back into the through-slot 7, where they are sieving again through the screen 3.
