[0003] The problem with existing technology is that existing screw conveyors usually require manual feeding into their hoppers during actual operation. Due to the limitations of manual operation, it is difficult to accurately control the amount and speed of each feeding, often resulting in too much material being fed in at once, which increases the probability of the screw conveyor clogging. At the same time, there is a lack of material dispersing function during the material feeding stage. Powdered materials may clump due to moisture, and clumped materials entering the screw conveyor are more likely to cause blockage. Summary of the Invention

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a feeding device for PVC plastic material production, which has the advantages of breaking up clumped powder materials and feeding them evenly. This solves the problem that existing screw feeders usually require manual feeding into their hoppers during actual operation. Due to the limitations of manual operation, it is difficult to accurately control the amount and speed of each feeding, often resulting in too much material being fed at once, increasing the probability of clogging the screw feeder. At the same time, the lack of a material breaking function during the material feeding stage means that the powder material may clump due to moisture, and clumped material entering the screw feeder is more likely to cause clogging problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for PVC plastic material production, comprising a screw feeder and a hopper, wherein a uniform feeding mechanism is provided at the top of the hopper.

[0006] The uniform feeding mechanism includes a support plate, the bottom of which is fixedly connected to the hopper, and the top of which is fixedly connected to a feeding box. A guide plate is fixedly connected to the right side of the top of the feeding box.

[0007] A dispersing component is provided on the left side of the bottom of the inner cavity of the feeding box, and a frame is provided at the bottom of the dispersing component. A screen is fixedly connected to the bottom of the inner cavity of the frame.

[0008] The front side of the frame is provided with a linkage component that works in conjunction with the distributed components.

[0009] In a preferred embodiment of this invention, the dispersing assembly includes a drive shaft, a servo motor, and a rotating disk. The front side of the drive shaft passes through the feeding box and extends to the outside of the feeding box, where it is fixedly connected to the rotating disk. It is also rotatably connected to the feeding box through a bearing. The rear side of the drive shaft passes through the feeding box and extends to the outside of the feeding box, where it is fixedly connected to the output end of the servo motor. The bottom of the servo motor is fixedly connected to a support plate.

[0010] As a preferred embodiment of this invention, the surface of the drive shaft is fitted with a disintegrating component, the disintegrating component being multiple in number and evenly distributed in a linear array, and fixedly connected to the drive shaft.

[0011] As a preferred embodiment of this utility model, the linkage component includes a linkage plate, which is fixedly connected to the frame on the side near the frame, and a connecting rod is provided on the top of the rear side of the linkage plate.

[0012] As a preferred embodiment of this utility model, a rectangular through hole is provided on the front side of the bottom of the support plate, the top of the linkage plate passes through the rectangular through hole and extends to the outside of the rectangular through hole to be rotatably connected to the connecting rod, and the side of the connecting rod away from the linkage plate is rotatably connected to the rotating disk.

[0013] As a preferred embodiment of this utility model, the inner cavity of the rectangular through hole is provided with a support column, both ends of which are fixedly connected to the inner wall of the rectangular through hole. The middle of the linkage plate is sleeved on the surface of the support column and is slidably connected to the support column through a linear bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model solves the problem of existing screw conveyors, which usually require manual feeding into their hoppers during actual operation. Due to the limitations of manual operation, it is difficult to accurately control the amount and speed of each feeding, often resulting in too much material being poured in at once, increasing the probability of clogging. At the same time, the lack of material dispersing function during the material feeding process means that powdered materials may clump due to moisture. Clumped material entering the screw conveyor is more likely to cause clogging. This utility model achieves the effect of dispersing and uniformly feeding clumped powdered materials during the feeding process, thus avoiding clogging of the screw conveyor.

[0016] 2. By setting up a dispersing component, this utility model can break up agglomerated powder materials, reduce the risk of clogging of the screw feeder, and also drive the linkage component to move back and forth.

[0017] 3. This utility model, by setting up a linkage component and a screen, allows the powder material to be fed evenly by driving the screen to move back and forth, avoiding excessive feeding at one time and causing blockage of the screw conveyor, thus improving the stability of operation.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0026] Reference Figure 1-3This is the first embodiment of the present invention, which provides a feeding device for PVC plastic material production, including a screw feeder 1 and a hopper 2, wherein a uniform feeding mechanism 3 is provided on the top of the hopper 2.

[0027] The uniform feeding mechanism 3 includes a support plate 31. The bottom of the support plate 31 is fixedly connected to the hopper 2, and the top of the support plate 31 is fixedly connected to the feeding box 32. The right side of the top of the inner cavity of the feeding box 32 is fixedly connected to the guide plate 33.

[0028] A dispersing component 34 is provided on the left side of the bottom of the inner cavity of the feeding box 32. A frame 35 is provided at the bottom of the dispersing component 34. A screen 36 is fixedly connected to the bottom of the inner cavity of the frame 35.

[0029] The front side of the frame 35 is provided with a linkage component 37 that works in conjunction with the dispersion component 34.

[0030] Specifically, by setting up the dispersing component 34, the agglomerated powder material can be broken up, reducing the risk of blockage of the screw feeder 1, and the linkage component 37 can also be driven to move back and forth.

[0031] By setting up the linkage component 37, frame 35 and screen 36, the linkage component 37 drives the screen 36 to move back and forth through the frame 35, so that the powder material is fed evenly, avoiding excessive feeding at one time, which would cause the screw feeder 1 to be blocked, and improving the stability of the operation.

[0032] By incorporating the feeding box 32 and the guide plate 33, the powder material can be protected, preventing excessive dispersion during feeding and dispersing. Furthermore, during feeding, the guide plate 33 directs the powder material towards the dispersing component, facilitating its dispersal.

[0033] Furthermore, during operation, the powder material is poured into the feed box 32 and flows to the dispersing component through the guide plate 33. At the same time, the dispersing component is activated to disperse the clumps of powder material. Then, the dispersed material falls into the inner cavity of the frame 35 and is evenly fed through the screen 36.

[0034] While the dispersing component disperses the powder material, it also drives the linkage component 37 to reciprocate, and links the frame 35 and the screen 36 to reciprocate synchronously, thereby improving the feeding efficiency of the screen 36. Example

[0035] In the second embodiment of this utility model, the dispersing component 34 includes a drive shaft 341, a servo motor 342, and a rotating disk 343. The front side of the drive shaft 341 passes through the feeding box 32 and extends to the outside of the feeding box 32, where it is fixedly connected to the rotating disk 343. It is also rotatably connected to the feeding box 32 through the through-hole via a bearing. The rear side of the drive shaft 341 passes through the feeding box 32 and extends to the outside of the feeding box 32, where it is fixedly connected to the output end of the servo motor 342. The bottom of the servo motor 342 is fixedly connected to the support plate 31.

[0036] The surface of the drive shaft 341 is fitted with a disintegrating component 344. There are multiple disintegrating components 344, which are evenly distributed in a linear array and are fixedly connected to the drive shaft 341.

[0037] Specifically, by setting a servo motor 342, the servo motor 342 provides power to drive the transmission shaft 341 and multiple disassembled parts 344 on the surface to rotate synchronously.

[0038] By setting the dispersing component 344, it can impact and disperse the powder material that clumps together during the falling process, thus preventing the clumps from entering subsequent stages and causing blockages.

[0039] By setting up a drive shaft 341 and a rotating disk 343, the rotation of the drive shaft 341 synchronously drives the rotating disk 343 on the front side to rotate, providing power to the linkage component 37, realizing the linkage between dispersing materials and driving uniform feeding, without the need for an additional power source, thus improving energy utilization.

[0040] Furthermore, during operation, the servo motor 342 is started, driving the transmission shaft 341 to rotate. Multiple dispersing components 344 on the surface of the transmission shaft 341 move in a circular motion. When the powder material falls from the top of the feed box 32 and is guided by the guide plate 33 to the area of ​​the dispersing component 34, the high-speed rotating dispersing components 344 will continuously impact the material, dispersing the agglomerated material. During this process, the rotating disk 343 at the front end of the transmission shaft 341 rotates synchronously with the transmission shaft 341, providing driving force for the movement of the linkage component 37. Example

[0041] In the third embodiment of this utility model, the linkage component 37 includes a linkage plate 371. The side of the linkage plate 371 near the frame 35 is fixedly connected to the frame 35, and a connecting rod 372 is provided on the top of the rear side of the linkage plate 371.

[0042] A rectangular through hole 4 is provided on the front side of the bottom of the support plate 31. The top of the linkage plate 371 passes through the rectangular through hole 4 and extends to the outside of the rectangular through hole 4 to be rotatably connected to the connecting rod 372. The side of the connecting rod 372 away from the linkage plate 371 is rotatably connected to the rotating disk 343.

[0043] The inner cavity of the rectangular through hole 4 is provided with a support column 5. Both ends of the support column 5 are fixedly connected to the inner wall of the rectangular through hole 4. The middle of the linkage plate 371 is sleeved on the surface of the support column 5 and is slidably connected to the support column 5 through a linear bearing.

[0044] Specifically, by setting up a linkage plate 371 and a connecting rod 372, the linkage plate 371 cooperates with the rotating disk 343 through the connecting rod 372 to form a crank-connecting rod 372 mechanism, which can convert the rotational motion of the rotating disk 343 into the reciprocating movement of the linkage plate 371, thereby driving the frame 35 and the screen 36 to perform reciprocating linear motion, so that the dispersed material can fall evenly through the screen 36 and avoid excessive material being fed at one time;

[0045] By setting rectangular through holes 4 and support columns 5, the linkage plate 371 can be supported and limited. The cooperation between the support column 5 and the linear bearing provides stable support and guidance for the movement of the linkage plate 371, reduces shaking and friction during the movement, and ensures the smoothness of the reciprocating motion of the screen 36.

[0046] Furthermore, when the rotating disk 343 rotates with the transmission shaft 341, it will drive the linkage plate 371 to reciprocate on the surface of the support column 5 through the connecting rod 372. The bottom of the linkage plate 371 is fixedly connected to the frame 35. Therefore, the frame 35 and the screen 36 inside reciprocate synchronously with the linkage plate 371, so that the material falling on the screen 36 passes through the screen 36 evenly in the reciprocating vibration and falls into the hopper 2 below.

[0047] During operation, PVC powder is poured into the feeding box 32. The material falls under the action of gravity and is guided by the guide plate 33 at the top of the inner cavity of the feeding box 32 to flow to the dispersing component 34 located on the left side of the bottom of the feeding box 32. At the same time, the servo motor 342 is started. The servo motor 342 outputs power to drive the transmission shaft 341 to rotate. Multiple dispersing components 344 on the surface of the transmission shaft 341 rotate synchronously at high speed with the transmission shaft 341, continuously impacting the material that is guided down by the guide plate 33, breaking up the clumps of material formed due to moisture and other reasons, and ensuring that the material is in a dispersed powder state.

[0048] While the drive shaft 341 rotates, the rotating disk 343 fixedly connected to its front side will rotate synchronously. The rotating disk 343 will convert its own circular motion into the pushing and pulling motion of the connecting rod 372 through the connecting rod 372. The connecting rod 372 drives the linkage plate 371 to reciprocate on the surface of the support column 5. The support column 5 is fixed on the support plate 31 through the rectangular through hole 4, providing stable guidance for the linkage plate 371. The bottom of the linkage plate 371 is fixedly connected to the frame 35. Therefore, the frame 35 and the screen 36 inside will reciprocate synchronously with the linkage plate 371. The powder material after being dispersed by the dispersing component 34 falls into the screen 36. Under the reciprocating vibration of the screen 36, it falls evenly through the screen 36 into the hopper 2 below, avoiding excessive material feeding at one time.

[0049] Finally, the material falling into hopper 2 enters screw conveyor 1, which completes the subsequent conveying process.

[0050] In summary, by setting up the uniform feeding mechanism 3, the agglomerated powder material is broken up and fed evenly during feeding, thus avoiding clogging of the screw feeder.
