Description

Technical Field

[0001] This application relates to the technical field of plastic particle transportation and manufacturing, and particularly to a PVC pellet processing and transportation mechanism. Background Art

[0002] When producing plastic particles such as PVC pellets, a standard judgment on the particle size is required. Although current production equipment has largely avoided non-standard production during production, the existing technology still cannot avoid this situation. When unqualified plastic particles are mixed into transportation or packaging, it will reduce the product quality, and over time, it will affect the product sales.

[0003] Upon retrieval, in the application with the patent publication number CN219210602U, a plastic pellet processing and transportation mechanism is disclosed, including a screening frame. A sieve plate is assembled inside the screening frame, and a guide plate is also arranged above the sieve plate inside the screening frame. Left and right material grooves with the same specifications are opened on the side wall of the screening frame, and both the left and right material grooves are arranged on the lower side of the sieve plate.

[0004] For this plastic pellet processing and transportation mechanism, through the setting of the inclined sieve plate inside the screening frame, the plastic material pile on its top side can be screened accordingly. And the setting of the guide plate on the top side of the sieve plate can create a set of material gaps between its bottom end and the sieve plate. All discharged plastic particles need to pass through the material gaps, thus ensuring that all plastic particles come into contact with the sieve plate and ensuring the screening effect of the sieve holes on the sieve plate for plastic particles, avoiding the situation where some unscreened plastic particles are directly discharged. In addition, multiple groups of sieve plates and guide plates can be set inside the screening frame according to needs, enabling different specifications of screening of the material pile at one time to ensure the screening effect. However, during the screening process, large plastic particles are likely to block the mesh holes, affecting the falling of small plastic particles, resulting in poor screening effect, and it is rather troublesome for subsequent operators to clean the sieve plate. Therefore, there is still room for improvement. Summary of the Utility Model

[0005] In order to improve the screening effect of PVC pellets and facilitate the cleaning by operators, this application provides a PVC pellet processing and transportation mechanism.

[0006] A PVC pellet processing and transportation mechanism provided by this application adopts the following technical solutions:

[0007] A PVC pellet processing and conveying mechanism includes a screening frame. A sieve plate is assembled inside the screening frame. The sieve plate is inclined. A number of sieve holes are provided on the sieve plate. A guide plate is also provided inside the screening frame above the sieve plate. An outlet is provided on the side wall of the screening frame, and the outlet is arranged at the end position of the sieve plate. A vibration mechanism is provided on the screening frame, and the vibration mechanism is used to drive the sieve plate to vibrate.

[0008] By adopting the above technical solution, the PVC pellets are screened through the sieve plate. The vibration mechanism drives the sieve plate to vibrate during the screening process, so that the large-particle PVC pellets will vibrate relative to the sieve holes during the screening process and are not easily blocked by the sieve holes, reducing the occurrence of the situation where the large-particle PVC pellets block the sieve holes and affect the falling of the small-particle PVC pellets, thereby improving the screening effect. The non-blocking of the sieve holes also makes it more convenient for the operator to clean the sieve plate.

[0009] Preferably, the vibration mechanism includes a driving motor and a cam member. The cam member is fixed on the output shaft of the driving motor, and the bottom of the sieve plate abuts against the cam member.

[0010] By adopting the above technical solution, the driving motor drives the cam member to rotate. During the rotation of the cam member, it continuously pushes the sieve plate, causing the sieve plate to vibrate. The structure is simple and easy to implement.

[0011] Preferably, a limiting groove is provided on the screening frame, and one end of the sieve plate close to the driving motor is accommodated in the limiting groove.

[0012] By adopting the above technical solution, the limiting groove limits the end of the sieve plate, so that the sieve plate is not easily overly amplitude during vibration, improving the vibration stability of the sieve plate.

[0013] Preferably, a positioning rod is fixed on the screening frame, and one end of the sieve plate far from the driving motor is sleeved on the positioning rod.

[0014] By adopting the above technical solution, one end of the sieve plate far from the driving motor is sleeved on the positioning rod. During the vibration of the sieve plate, the positioning rod plays a limiting role on the sieve plate, so that the sieve plate is not easily sway left and right during vibration, further improving the vibration stability of the sieve plate.

[0015] Preferably, a through hole is provided on the screening frame, and the shape and size of the through hole are the same as the cross-sectional shape and size of the sieve plate in the width direction.

[0016] By adopting the above technical solution, the setting of the through hole enables the sieve plate to be taken out of the screening frame through the through hole, facilitating the cleaning of the sieve plate.

[0017] Preferably, a pull rod is fixed on the sieve plate, and the pull rod penetrates through the through hole and extends out of the screening frame.

[0018] By adopting the above technical solution, the operator can pull the pull rod to pull the sieve plate out of the through hole, which is convenient for the operator to take out the sieve plate.

[0019] Preferably, a clearance hole is formed on the screening frame, and the clearance hole communicates with the through hole. The clearance hole is used for avoiding the position of the pull rod.

[0020] By adopting the above technical solution, the clearance hole plays a role in avoiding the position of the pull rod, so that the pull rod has a free movement space during the vibration of the sieve plate, which is beneficial to the vibration of the sieve plate.

[0021] Preferably, a receiving frame is installed on the outer side wall of the screening frame and is located below the discharge port. The receiving frame is in snap-fit connection with the screening frame.

[0022] By adopting the above technical solution, the snap-fit connection between the receiving frame and the screening frame enables the receiving frame to be removed from the screening frame, which is convenient for the operator to unload the material.

[0023] To sum up, the present application includes at least one of the following beneficial technical effects: The PVC pellets are screened through the sieve plate, and the vibration mechanism drives the sieve plate to vibrate during the screening process, so that the large-particle PVC pellets will vibrate relative to the sieve holes during the screening process and are not easily blocked by the sieve holes, reducing the situation that the large-particle PVC pellets block the sieve holes and affect the falling of the small-particle PVC pellets, thereby improving the screening effect. The unblocked sieve holes also make it more convenient for the operator to clean the sieve plate. Description of the Drawings

[0028] The following Figures 1-3 further describes the present application in detail.

[0029] An embodiment of the present application discloses a PVC pellet processing and conveying mechanism. Refer to Figure 1 and Figure 2 , a PVC pellet processing and conveying mechanism includes a screening frame 1, three groups of sieve plates 2 are arranged inside the screening frame 1, the sieve plates 2 are inclined, the distances between the three groups of sieve plates 2 are the same, and the directions of adjacent sieve plates 2 are different. Sieve holes 3 are opened on multiple groups of sieve plates 2 inside the screening frame 1, and the radii of the sieve holes 3 on the three sieve plates 2 decrease gradually from top to bottom. A guide plate 4 is also fixed inside the screening frame 1 above the sieve plate 2, the number of guide plates 4 corresponding to the sieve plates 2 is three, the guide plate 4 is inclined, the inclination direction of the guide plate 4 is different from the inclination direction of the sieve plate 2, and a corresponding material gap is arranged between the bottom end of the guide plate 4 and the top surface of the sieve plate 2. An outlet 5 is opened on the side wall of the screening frame 1, the outlet 5 is correspondingly arranged at the end position of the sieve plate 2, and a vibration mechanism 6 is arranged on the screening frame 1, and the vibration mechanism 6 is used to drive the sieve plate 2 to vibrate.

[0030] Correspondingly, when it is necessary to screen PVC pellets, the operator pours the PVC pellets into the screening frame 1, the PVC pellets contact the uppermost guide plate 4 and fall onto the uppermost sieve plate 2 under the guiding action of the guide plate 4. The PVC pellets smaller than the aperture of the sieve holes 3 on the uppermost sieve plate 2 pass through the sieve holes 3 and fall onto the next lower guide plate 4 or sieve plate 2, and the PVC pellets larger than the aperture of the sieve holes 3 on the uppermost sieve plate 2 pass through the material gap in the inclined direction of the sieve plate 2 and are discharged from the outlet 5. The PVC pellets that fall onto the next lower guide plate 4 or sieve plate 2 continue to be screened by the next lower sieve plate 2, and the screened PVC pellets are discharged from the bottom of the screening frame 1. During the screening process, the vibration mechanism 6 drives the sieve plate 2 to vibrate during the screening process, so that the large-particle PVC pellets will vibrate relative to the sieve holes 3 during the screening process and are not easily blocked by the sieve holes 3. The situation where the sieve holes 3 are blocked by large-particle PVC pellets and affect the falling of small-particle PVC pellets is reduced, thereby improving the screening effect, and the non-blocking of the sieve holes 3 also makes it more convenient for the operator to clean the sieve plate 2.

[0031] Specifically, refer to Figure 2 and Figure 3, the vibration mechanism 6 includes a drive motor 61 and a cam member 62. The cam member 62 is fixed to the output shaft of the drive motor 61, and the bottom of the sieve plate 2 abuts against the cam member 62. The distances from the points on the outer peripheral contour of the cam member 62 to the output shaft of the drive motor 61 are different. The sieve plate 2 is lapped on the cam member 62, and when the cam member 62 rotates, the sieve plate 2 vibrates. Two cam members 62 are provided at the bottom of one end of each sieve plate 2, and two drive motors 61 are correspondingly provided. The drive motor 61 drives the cam member 62 to rotate, and the rotation of the cam member 62 causes the sieve plate 2 to vibrate, so that the large PVC pellets will vibrate relative to the sieve holes 3 during the screening process and are not easily blocked by the sieve holes 3. A limiting groove 7 is provided on the screening frame 1, and one end of the sieve plate 2 close to the drive motor 61 is received in the limiting groove 7. The groove wall of the limiting groove 7 plays a limiting role on the sieve plate 2, so that the sieve plate 2 is not easily over-amplified during vibration, and the vibration stability of the sieve plate 2 is improved. A positioning rod 8 is fixed on the screening frame 1. The positioning rod 8 is horizontally arranged. One end of the positioning rod 8 is fixedly connected to the inner wall of the screening frame 1, and the other end of the positioning rod 8 is a free end. One end of the sieve plate 2 far from the drive motor 61 is sleeved on the positioning rod 8 from the free end of the positioning rod 8. During the vibration of the sieve plate 2, the positioning rod 8 plays a limiting role on the sieve plate 2, so that the sieve plate 2 is not easily swayed left and right during vibration, and the vibration stability of the sieve plate 2 is further improved.

[0032] Further, looking back Figure 1 and Figure 2 , a through hole 9 is provided on the screening frame 1. The shape and size of the through hole 9 are the same as the cross-sectional shape and size of the sieve plate 2 in the width direction. A pull rod 10 is fixed on the sieve plate 2. The pull rod 10 passes through the through hole 9 and extends out of the screening frame 1. When the screening operation of the PVC pellets is completed, the operator can pull the pull rod 10 to pull the sieve plate 2 out of the through hole 9, so as to facilitate the cleaning of the sieve plate 2. A relief hole 11 is provided on the screening frame 1. The relief hole 11 communicates with the through hole 9. The relief hole 11 is used to provide a relief position for the pull rod 10. The relief hole 11 plays a relief role on the pull rod 10, so that the pull rod 10 has a free movement space during the vibration of the sieve plate 2, reducing the hindrance to the vibration of the sieve plate 2, and thus better ensuring the normal vibration operation of the sieve plate 2.

[0033] In addition, a receiving frame 12 is installed on the outer side wall of the screening frame 1 below the discharge port 5. A clamping groove is provided on the screening frame 1, and a clamping block is fixed on the receiving frame 12. The clamping block is clamped and matched with the clamping groove. The clamping and matching of the receiving frame 12 and the screening frame 1 enables the receiving frame 12 to be removed from the screening frame 1, facilitating the operator to unload the material.

[0034] The implementation principle of a PVC pellet processing and conveying mechanism according to an embodiment of the present application is:

[0035] When the mechanism needs to work, pour PVC pellets into the screening frame 1, so that the pellets pass through the material gap between the guide plate 4 and the sieve plate 2 and evenly contact the sieve holes 3 on the sieve plate 2, ensuring the screening effect of the sieve holes 3 on the PVC pellets. The PVC pellets that do not meet the requirements will be discharged outward through the discharge port 5 on the bottom side of the corresponding sieve plate 2 into the receiving frame 12, ensuring the screening effect and enabling the screening of PVC pellets in different specifications at the same time.

[0036] For this PVC pellet processing and conveying mechanism, through the setting of the inclined sieve plate 2 inside the screening frame 1, the PVC pellet pile on its top side can be screened accordingly. And the setting of the guide plate 4 on the top side of the sieve plate 2 can create a set of material gaps between its bottom end and the sieve plate 2. All the discharged PVC pellets need to pass through the material gaps, and then it can be ensured that all PVC pellets are in contact with the sieve plate 2, ensuring the screening effect of the sieve holes 3 on the sieve plate 2 for the PVC pellets and avoiding the situation where some unscreened PVC pellets are directly discharged. In addition, multiple groups of sieve plates 2 and guide plates 4 can be set inside the screening frame 1 according to needs, enabling the screening of the PVC pellet pile in different specifications at one time and ensuring its screening effect.

[0037] During the screening process, the driving motor 61 drives the cam member 62 to rotate, causing the sieve plate 2 to vibrate continuously during the screening process. The large-particle PVC pellets will vibrate relative to the sieve holes 3 during the screening process, making it difficult to block the sieve holes 3. This reduces the situation where the large-particle PVC pellets block the sieve holes 3 and affect the falling of the small-particle PVC pellets, thereby improving the screening effect. The non-blocking of the sieve holes 3 also makes it more convenient for the operator to clean the sieve plate 2.

[0038] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
