Description

Technical Field

[0001] This utility model relates to the field of PVC pipe processing technology, and in particular to a PVC pipe production wrapping device. Background Technology

[0002] Wrapping can prevent the pipe surface from being scratched by sharp objects or damaged by collisions during transportation. It can also isolate rainwater, mud, chemicals, etc., and prevent the pipe surface from blackening, corrosion or oxidation. In particular, PVC is prone to aging when exposed for a long time.

[0003] The wrapping of PVC pipes typically occurs at the end of the production line, specifically between the traction machine and the cutting machine. After the pipe is extruded, a protective film is directly wrapped around the surface of the pipe using a wrapping machine before cutting. This integrated process of "pipe making—wrapping—cutting" replaces the traditional manual wrapping method, resulting in higher efficiency and lower costs.

[0004] However, common wrapping equipment applies tension to the film during the wrapping process, causing wrinkles parallel to the length of the film to appear on the film surface. Air also exists in the wrinkles, resulting in insufficient and tight contact between the film and the pipe surface. When the pipe is cut later, the film that is not tightly attached to the pipe surface is prone to loosening and falling off, resulting in poor wrapping effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a PVC pipe production wrapping device, which solves the problem that the film does not adhere tightly to the pipe surface during wrapping, leading to easy loosening and detachment of the film.

[0007] In the above embodiment, a plate is provided, and a rotating ring is installed on one side of the feed hole in the middle of the plate. The hollow area in the middle of the feed hole and the rotating ring is used to pass through the pipe. During operation, the drive unit is activated to drive the rotating ring, and the rotating ring drives the film to wrap around the outside of the pipe. At the same time, the smoothing unit 400 contacts the film wrapped on the pipe to smooth the film, expel the air in the wrinkles of the film, so that the film can stick tightly to the pipe, avoid the film from loosening and falling off when the pipe is cut, and ensure the film wrapping effect.

[0008] In some embodiments, the rotating ring is coaxially arranged with the feed hole, and the outer edge of the rotating ring is provided with a first support plate and a second support plate at right angles. The first support plate and the second support plate are respectively rotatably mounted with a film material shaft and a limiting shaft on the side away from the plate body.

[0009] In some embodiments, the centerline of the film material shaft and the centerline of the limiting shaft are both at an angle to the centerline of the rotating ring.

[0010] In some embodiments, the drive includes a motor mounted through the plate and a gear fixedly mounted on the output shaft of the motor, the gear meshing with the tooth groove.

[0011] In some embodiments, the smoothing member includes a third support plate disposed opposite to the first support plate and fixedly connected to the outer edge of the rotating ring, and a rotating shaft fixedly installed on the third support plate away from the plate body. A smoothing plate is rotatably mounted on the outside of the rotating shaft, and an elastic member is provided on one side of the smoothing plate.

[0012] In some embodiments, a contact membrane recess is provided on the top side of the flat surface, and a pressing strip is provided in the contact membrane recess.

[0013] In some embodiments, the elastic element includes a support rod fixedly installed at the bottom of the third support plate and an arc-shaped rod fixedly installed at one end of the support rod. The other end of the arc-shaped rod extends through to the outside of one side of the flat plate.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] In an exemplary implementation, such as Figures 1-4 As shown, this embodiment provides a PVC pipe production wrapping device, including a plate 100, a rotating ring 200, a driving component 300, and a smoothing component 400. The plate 100 has a through material feeding hole 110 in the middle. The rotating ring 200 is rotatably mounted on one end of the material feeding hole 110 and is used to load the film material. The driving component 300 is mounted on the plate 100 and is used to drive the rotating ring 200 to rotate. The smoothing component 400 is mounted on the outer edge of the rotating ring 200 and is used to smooth the film wrapped on the pipe.

[0024] In this embodiment, a plate 100 is provided, and a rotating ring 200 is installed on one side of the feed hole 110 in the middle of the plate 100. The hollow area in the middle of the feed hole 110 and the rotating ring 200 is used to pass through the pipe. During operation, the drive unit 300 is started to drive the rotating ring 200, and the rotating ring 200 drives the film material to wrap around the outside of the pipe. At the same time, the smoothing unit 400 contacts the film wrapped on the pipe to smooth the film, expel the air in the wrinkles of the film, so that the film can stick tightly to the pipe, avoid the film from loosening and falling off when the pipe is cut, and ensure the film wrapping effect.

[0025] In one embodiment, please refer to Figure 1 and Figure 2 The rotating ring 200 is coaxially arranged with the feed hole 110. The outer edge of the rotating ring 200 is provided with a first support plate 210 and a second support plate 220 at right angles. The first support plate 210 and the second support plate 220 are respectively rotatably mounted on the side away from the plate body 100. The rotating ring 200 is provided with evenly spaced toothed grooves 250 near the outer edge of the plate body 100.

[0026] In this embodiment, the film material shaft 230 on the first support plate 210 is used to install the film material, and the limiting shaft 240 on the second support plate 220 is used to limit the film. In specific operation, the end of the film material is wrapped around the side of the limiting shaft 240 away from the pipe, and then the film material is pulled upward and wrapped around the pipe.

[0027] The centerlines of the film material shaft 230 and the limiting shaft 240 are both at an angle to the centerline of the rotating ring 200. In layman's terms, the film material shaft 230 and the limiting shaft 240 are both inclined, so that the film material can be wound on the tube at an inclined angle, thereby improving the winding efficiency.

[0028] In one embodiment, please refer to Figures 1-4 The drive unit 300 includes a motor 310 mounted through the plate 100 and a gear 320 fixedly mounted on the output shaft of the motor 310. The gear 320 meshes with the tooth groove 250.

[0029] In this embodiment, the motor 310 drives the gear 320 to rotate, and the gear 320 meshes with the tooth groove 250 on the outer edge of the rotating ring 200, thereby driving the rotating ring 200 to rotate.

[0030] In one embodiment, please refer to Figure 1 and Figure 2 The smoothing component 400 includes a third support plate 410 disposed opposite to the first support plate 210 and fixedly connected to the outer edge of the rotating ring 200, and a rotating shaft 420 fixedly installed on the third support plate 410 away from the plate body 100. A smoothing plate 430 is rotatably installed on the outside of the rotating shaft 420. An elastic element 440 is provided on one side of the smoothing plate 430. A contact membrane recess 431 is provided on the top of one side of the smoothing plate 430. A pressing strip 432 is provided in the contact membrane recess 431. The elastic element 440 includes a support rod 441 fixedly installed on the bottom of the third support plate 410 and an arc-shaped rod 442 fixedly installed on one end of the support rod 441. The other end of the arc-shaped rod 442 extends to the outside of one side of the smoothing plate 430. A spring 443 is sleeved on the outside of the arc-shaped rod 442, with both ends fixedly connected to the smoothing plate 430 and the support rod 441 respectively.

[0031] In this embodiment, the smoothing plate 430 is rotatably mounted on the outside of the rotating ring 200 via the rotating shaft 420. Then, the smoothing plate 430 is always moved closer to the pipe by the spring 443 outside the arc rod 442, so that the pressing strip 432 in the contact membrane recess 431 of the smoothing plate 430 can be tightly attached to the pipe, thereby smoothing the membrane.

[0032] In one embodiment, please refer to Figures 1-3 The feed hole 110 is equidistantly and flexibly equipped with several support wheels 500. The support wheels 500 can keep the pipe in the center of the rotating ring 200, improving the stability during operation.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: In use, the tube passes through the hollow area between the feed hole 110 and the rotating ring 200. The motor 310 is started, and the motor 310 drives the gear 320 to rotate. The gear 320 meshes with the tooth groove 250 on the outer edge of the rotating ring 200, thereby driving the rotating ring 200 to rotate. The rotation of the rotating ring 200 can drive the film material outside the film material shaft 230 to wrap around the outside of the tube. Specifically, the end of the film material is wound around the side away from the tube from the limiting shaft 240. Then, the film material is pulled upward and wrapped around the pipe. At the same time, the smoothing plate 430 is rotated and installed outside the rotating ring 200 via the rotating shaft 420. Then, the spring 443 outside the arc rod 442 keeps the smoothing plate 430 close to the pipe side, so that the pressing strip 432 in the contact recess 431 of the smoothing plate 430 can stick tightly to the pipe, smooth the film, expel the air in the wrinkles of the film, so that the film can stick tightly to the pipe, avoid the film from loosening and falling off when the pipe is cut, and ensure the film wrapping effect.

[0034] In summary, this utility model solves the technical problem in existing wrapping devices where the film does not adhere tightly enough to the pipe surface during wrapping, leading to easy loosening and detachment of the film, by using a smoothing component 400 on the outside of the rotating ring 200 to smooth the film wrapped around the outside of the pipe. This achieves the technical effect of improving the stability during operation.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
