Description
Technical Field
[0001] This utility model belongs to the field of PVC pipe processing technology, and in particular relates to a PVC pipe processing and forming device. Background Technology
[0002] A plastic extruder is a type of plastic pipe forming device. It heats and plasticizes molten plastic raw materials, then steadily conveys them to the die head. After forming the pipe blank, it passes through a shaping and cooling device to achieve the required geometric shape and dimensional accuracy. This process includes key stages such as plasticizing, forming, and sizing, ensuring continuous production and quality stability of plastic pipes.
[0003] The problem with existing technology is that, when using existing plastic extruders, users usually need to add the raw materials into the inner cavity of the extruder hopper. However, when the material is being fed into the hopper, it may clump together due to moisture or prolonged storage, forming large lumps. These lumps accumulate at the feed inlet, hindering the smooth entry of subsequent materials. In addition, when the particle size and shape of the material are uneven, bridging can easily form in the feed hopper, where the materials support each other to form a stable structure, leading to blockage of the feed channel.

[0026] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] like Figures 1 to 4 As shown in the figure, a PVC pipe processing and forming device provided by this utility model includes an extruder 1 and a hopper 2. The hopper 2 is fixedly connected to the top of the extruder 1. A protective cover 3 is provided on the top of the hopper 2. A stirring assembly 4 is provided in the inner cavity of the hopper 2. A driving device 5 that works with the stirring assembly 4 is provided at the center of the top of the protective cover 3. A striking device 6 that works with the driving device 5 is provided on the left and right sides of the hopper 2. A feeding port 7 is fixedly connected to the front side of the top of the protective cover 3. A support plate 8 that works with the driving device 5 is fixedly connected to the rear side of the top of the protective cover 3.
[0028] refer to Figure 2 The stirring assembly 4 includes a drive column 401 and stirring rods 402. There are multiple stirring rods 402, which are evenly distributed on both sides of the curved surface of the drive column 401. The top of the drive column 401 passes through the protective cover 3 and extends to the outside of the protective cover 3.
[0029] The above solution is adopted: by setting the stirring component 4, the material in the inner cavity of the hopper 2 can be dispersed to prevent the material from clumping and facilitate the feeding of the hopper 2. By setting the transmission column 401, the stirring rod 402 can be driven to rotate. By setting the stirring rod 402, the raw materials in the inner cavity of the hopper 2 can be dispersed.
[0030] refer to Figure 3 The drive device 5 includes a motor 501, and a cam 502 is fixedly connected to the output end of the motor 501. Contact wheels 503 are provided on the inner sides of the front and rear sides of the cam 502.
[0031] By adopting the above solution, the driving device 5 can drive the stirring component 4 and the tapping device 6, making it convenient for users to use the stirring component 4 and the tapping device 6.
[0032] refer to Figure 2and Figure 3 The striking device 6 includes a transmission rod 601, a movable plate 602 fixedly connected to the left side of the transmission rod 601, springs 603 fixedly connected to the front and rear sides of the left side of the movable plate 602, a striking plate 604 fixedly connected to the bottom of the movable plate 602, and a rubber pad 605 fixedly connected to the side of the striking plate 604 near the hopper 2.
[0033] The above solution is adopted: by setting up the tapping device 6, the hopper 2 can be tapped, so that the raw material is discharged more smoothly into the inner cavity of the hopper 2 and the material is prevented from clogging the inner cavity of the hopper 2.
[0034] refer to Figure 4 Positioning plates 9 are fixedly connected to the top of the left and right sides of the hopper 2. A rectangular through hole 10 is opened on the top of the positioning plate 9. Support columns 11 that cooperate with the striking device 6 are provided on the front and rear sides of the inner cavity of the rectangular through hole 10. The left and right sides of the support columns 11 are fixedly connected to the inner wall of the rectangular through hole 10.
[0035] The above solution is adopted: by setting the positioning plate 9 and the rectangular through hole 10, the moving plate 602 can be limited, and by setting the support column 11, the moving plate 602 can be supported.
[0036] refer to Figure 2 and Figure 3 The rear side of the motor 501 is fixedly connected to the support plate 8, the bottom of the cam 502 is fixedly connected to the top of the stirring rod 402, and the top and bottom of the contact wheel 503 are rotatably connected to the inner side of the cam 502.
[0037] The above solution is as follows: by setting up a motor 501, the cam 502 and the transmission column 401 can be driven to rotate synchronously. By setting up a cam 502, the contact wheel 503 can be driven to rotate. By setting up a contact wheel 503, the transmission rod 601 can be moved, and the wear when in contact with the transmission rod 601 can be reduced.
[0038] refer to Figure 2 , Figure 3 and Figure 4 The movable plate 602 is provided inside the rectangular through hole 10 and is sleeved on the right side of the support column 11 and slidably connected to the support column 11. The spring 603 is sleeved on the left side of the support column 11 and the left side of the spring 603 is fixedly connected to the inner wall of the rectangular through hole 10. The rubber pad 605 is in contact with the hopper 2 on the side close to the hopper 2.
[0039] The above solution is as follows: by setting the transmission rod 601, the moving plate 602 can be moved; by setting the moving plate 602, the striking plate 604 can be moved; by setting the spring 603, the moving plate 602 can be reset; by setting the striking plate 604, the hopper 2 can be struck to prevent the raw material from blocking the inner cavity of the hopper 2; and by setting the rubber pad 605, wear during the striking can be reduced.
[0040] The working principle of this utility model:
[0041] When in use, the raw materials are added into the inner cavity of the hopper 2 through the feeding port 7, and then the motor 501 is started, which drives the cam 502 and the transmission column 401 to rotate synchronously. During the rotation of the transmission column 401, the stirring rod 402 will rotate to disperse the material in the inner cavity of the hopper 2 and prevent the raw materials from clumping.
[0042] Simultaneously, as the cam 502 rotates, it drives the contact wheel 503 to rotate as well. During this rotation, the contact wheel 503 contacts the transmission rod 601 and generates pressure. This pressure pushes the transmission rod 601 to move, which in turn moves the moving plate 602 on the surface of the support column 11, compressing the spring 603. The moving plate 602 then moves the striking plate 604 synchronously, preventing the rubber pad 605 from contacting the hopper 2. When the contact wheel 503 rotates to the appropriate position, it stops compressing the transmission rod 601, and the spring 603 is no longer compressed. The rebound force released by the compressed spring 603 pushes the moving plate 602 and the transmission rod 601 to move synchronously in opposite directions. The moving plate 602 then moves the striking plate 604 synchronously in opposite directions, causing the striking plate 604 to strike the hopper 2, making the material discharge smoother and preventing blockages during the discharge process, thus completing the task.
[0043] In summary, this PVC pipe processing and forming device, through the coordinated use of a protective cover 3, a stirring assembly 4, a driving device 5, a striking device 6, a feeding port 7, and a support plate 8, solves the problem that existing plastic extruders typically require users to add raw materials into the inner cavity of the extruder hopper. During feeding, the material may clump together due to moisture or prolonged storage, forming large lumps. These lumps accumulate at the feeding port, hindering the smooth entry of subsequent materials. Furthermore, when the particle size and shape of the material are uneven, bridging can easily form within the feeding hopper, where materials support each other, creating a stable structure that leads to blockage of the feeding channel.
