Description

Technical Field

[0001] This utility model relates to the field of PVC product processing technology, specifically a processing device for raw materials used in PVC product processing. Background Technology

[0002] The raw material for PVC (polyvinyl chloride) products is mainly vinyl chloride monomer. PVC products are usually made from vinyl chloride monomer through a series of processing steps.

[0003] In the process of PVC product processing, different PVC products have specific requirements for the particle size of raw materials. Therefore, it is necessary to screen the raw materials. Existing PVC product processing raw materials are screened by screen plates, and the screening efficiency of the screen plates is improved by corresponding shaking or vibration mechanisms. However, existing raw material particle screening devices are not convenient for cleaning raw material particles that do not meet the size requirements and accumulate on the screen plates, which will affect the screening effect of the screen plates. Therefore, those skilled in the art have proposed a processing device for PVC product processing raw materials to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a processing device for raw materials used in PVC product processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A processing device for raw materials used in PVC product processing includes a screening box, wherein an inner cavity and a discharge cavity are sequentially formed from top to bottom within the screening box, and an arc-shaped wall is provided at the connection between the inner cavity and the discharge cavity. Cleaning channels are provided on both sides of the discharge cavity within the screening box. The device also includes:

[0007] A support frame is provided, with rotating seats installed on both sides of the support frame. One end of the rotating seat is hinged to a movable plate, and the other end of the movable plate is fitted with an inner cavity. A screen is provided on the movable plate.

[0008] A support mechanism is provided between the movable plate and the support frame for adjusting the position of the movable plate;

[0009] The baffle is arc-shaped and fits against an arc-shaped wall. The arc-shaped wall is provided with an elastic mechanism connected to the baffle to provide elastic support for the baffle.

[0010] As a further embodiment of this utility model: a feeding rack is installed on the top of the screening box, and two symmetrically distributed feeding ports are opened on the feeding rack.

[0011] As a further embodiment of this utility model: the support mechanism includes a first connecting seat, a second connecting seat and a first hydraulic rod, the first connecting seat is connected to the support frame, the second connecting seat is connected to the movable plate, and the two ends of the first hydraulic rod are respectively hinged to the first connecting seat and the second connecting seat.

[0012] As a further improvement of this utility model: a fixing block is installed inside the inner cavity, and a second hydraulic rod is installed on the fixing block, and the second hydraulic rod is connected to the support frame.

[0013] As a further embodiment of this utility model: the elastic mechanism includes a support cylinder mounted on an arc-shaped wall, a slider slidably disposed inside the support cylinder, the slider being connected to a baffle via a connecting rod, and a spring connected to the slider being disposed inside the support cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model feeds raw material particles of PVC products into a screening box, and the raw material particles are screened by a screen on a movable plate. The raw material particles that meet the requirements are discharged from the discharge chamber, while the remaining raw material particles that do not meet the requirements are retained on the screen. When too many raw material particles that do not meet the requirements accumulate on the screen, in order to avoid affecting the screening efficiency of the screen, the drive support frame is lowered and the movable plate is brought into contact with the arc-shaped wall. Then, driven by the support mechanism, the movable plate rotates. During the rotation, the movable plate remains in contact with the arc-shaped wall and pushes the baffle to move, thereby opening the cleaning channel and allowing the raw material particles that do not meet the requirements on the screen to roll into the cleaning channel and be discharged. Afterwards, the support mechanism drives the movable plate to return to the horizontal position. Under the elastic force of the elastic mechanism, the baffle automatically returns to its original position and blocks the cleaning channel, thereby effectively cleaning the raw material particles that do not meet the requirements accumulated on the screen.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] Please see Figures 1-3 A processing device for raw materials used in PVC product processing includes a screening box 1. The screening box 1 has an inner cavity 2 and a discharge cavity 4 arranged sequentially from top to bottom. An arc-shaped wall 3 is provided at the connection between the inner cavity 2 and the discharge cavity 4. Cleaning channels 16 are provided on both sides of the discharge cavity 4 within the screening box 1. The device also includes:

[0021] Support frame 7, rotating seats 8 are installed on both sides of support frame 7, one end of rotating seat 8 is hinged to movable plate 9, the other end of movable plate 9 is attached to inner cavity 2, and screen 10 is provided on movable plate 9;

[0022] A support mechanism is provided between the movable plate 9 and the support frame 7 for adjusting the position of the movable plate 9;

[0023] The baffle 17 is arc-shaped and fits against the arc-shaped wall 3. The arc-shaped wall 3 is provided with an elastic mechanism connected to the baffle 17 to provide elastic support for the baffle 17.

[0024] By feeding PVC raw material granules into the screening box 1, the raw material granules are screened by the screen 10 on the movable plate 9. The raw material granules that meet the requirements are discharged from the discharge chamber 4, while the remaining raw material granules that do not meet the requirements are retained on the screen 10. When too many raw material granules that do not meet the requirements accumulate on the screen 10, in order to avoid affecting the screening efficiency of the screen 10, the drive support frame 7 is lowered and the movable plate 9 is brought into contact with the arc-shaped wall 3. Then, driven by the support mechanism, the movable plate 9 is rotated. During the rotation, the movable plate 9 remains in contact with the arc-shaped wall 3 and pushes the baffle 17 to move, thereby opening the cleaning channel 16. This allows the raw material granules that do not meet the requirements on the screen 10 to roll into the cleaning channel 16 and be discharged. Afterward, the support mechanism drives the movable plate 9 to return to the horizontal position. Under the elastic force of the elastic mechanism, the baffle 17 automatically returns to its original position and blocks the cleaning channel 16, thereby effectively cleaning the raw material granules that do not meet the requirements accumulated on the screen 10.

[0025] In one embodiment, a feeding rack 5 is installed on the top of the screening box 1, and two symmetrically distributed feeding ports 6 are opened on the feeding rack 5.

[0026] By feeding the raw material granules of PVC products into the feeding rack 5, the raw material granules will fall from the feeding port 6 onto the two screens 10.

[0027] In one embodiment, the support mechanism includes a first connecting seat 11, a second connecting seat 13, and a first hydraulic rod 12. The first connecting seat 11 is connected to the support frame 7, the second connecting seat 13 is connected to the movable plate 9, and the two ends of the first hydraulic rod 12 are hinged to the first connecting seat 11 and the second connecting seat 13, respectively.

[0028] The movable plate 9 can be supported by the first hydraulic rod 12. During the screening process, the first hydraulic rod 12 will drive the movable plate 9 to rotate to a horizontal position. When it is necessary to clean the raw material particles on the screen 10 that do not meet the requirements, the support frame 7 is driven to descend and make the movable plate 9 fit against the arc wall 3. Then the first hydraulic rod 12 will retract and drive the movable plate 9 to rotate downward, which can push the baffle 17 to move and open the cleaning channel 16.

[0029] In one embodiment, a fixing block 14 is installed inside the inner cavity 2, and a second hydraulic rod 15 is installed on the fixing block 14. The second hydraulic rod 15 is connected to the support frame 7.

[0030] During the screening of raw material particles, the support frame 7 can be driven to move up and down repeatedly by the second hydraulic rod 15, causing the screen 10 to shake up and down, thereby improving the screening efficiency of the screen 10 for raw material particles. When it is necessary to clean the raw material particles on the screen 10 that do not meet the requirements, the support frame 7 can be driven to descend by the second hydraulic rod 15, causing the movable plate 9 to fit against the arc-shaped wall 3.

[0031] In one embodiment, the elastic mechanism includes a support cylinder 18 mounted on the arc-shaped wall 3, a slider 19 slidably disposed inside the support cylinder 18, the slider 19 being connected to the baffle 17 via a connecting rod 21, and a spring 20 connected to the slider 19 being disposed inside the support cylinder 18.

[0032] When the movable plate 9 rotates along the arc-shaped wall 3 and pushes the baffle 17 to move, the connecting rod 21 will push the slider 19 to slide and squeeze the spring 20. When the movable plate 9 is reset, the slider 19 can be reset by the spring 20, that is, the baffle 17 can be reset by the connecting rod 21 to re-seal the cleaning channel 16.

[0033] This invention involves feeding PVC raw material granules into a screening box 1, where the granules are screened by a screen 10 on a movable plate 9. Qualified granules are discharged from the discharge chamber 4, while unqualified granules remain on the screen 10. When too many unqualified granules accumulate on the screen 10, to avoid affecting the screening efficiency, the drive support frame 7 is lowered, causing the movable plate 9 to contact the arc-shaped wall 3. Driven by the support mechanism, the movable plate 9 rotates, maintaining contact with the arc-shaped wall 3 and pushing the baffle 17 to open the cleaning channel 16. This allows unqualified granules on the screen 10 to roll into the cleaning channel 16 and be discharged. Afterward, the support mechanism drives the movable plate 9 back to a horizontal position. Under the elastic force of the elastic mechanism, the baffle 17 automatically resets and blocks the cleaning channel 16, effectively cleaning the unqualified granules accumulated on the screen 10.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
