Description

Technical Field

[0001] This utility model belongs to the field of corrugated pipe coating technology, and in particular relates to a PVC corrugated pipe surface coating equipment. Background Technology

[0002] A bellows is a tubular elastic sensitive element made of foldable corrugated sheets connected along the folding and stretching direction. During the production of bellows, their surface needs to be coated to improve their service life.

[0003] A search revealed a Chinese patent, CN114618739B, which discloses a corrugated pipe surface coating device. This technical solution adds a walking elastic coating roller to ensure the uniformity of the surface coating of the corrugated pipe and prevent uneven surface coating. At the same time, it adds an adjustable angle coating roller structure to ensure that a single coating roller can adapt to both annular and spiral corrugated pipes, increasing the versatility of the coating device and optimizing the coating effect of the coating roller.

[0004] However, when using the above-mentioned device, the coated corrugated pipe needs to be clamped and fixed at both ends by a three-jaw chuck, which makes it impossible to perform traction coating operations on long corrugated pipes, resulting in poor adaptability.

[0005] To address the aforementioned issues, this application proposes a PVC corrugated pipe surface coating device. Utility Model Content

[0006] The purpose of this invention is to provide a PVC corrugated pipe surface coating device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a PVC corrugated pipe surface coating device, including a corrugated pipe and a fixing frame;

[0009] The coating unit contains two coating rollers, which are distributed opposite to each other and staggered on both sides of the fixing frame. The outer side has arc-shaped protrusions to fill the troughs of the fixing frame.

[0010] The rotating rods are located at both ends of the coating roller, perpendicular to the cross-section of the coating roller and extending towards the side wall of the fixed frame. Their rotational motion causes the coating roller to roll.

[0011] Furthermore, when viewed from the front, the upper and lower ends of adjacent coating rollers overlap.

[0012] Furthermore, the bottom of the fixing frame is provided with a liquid storage section, and above it is provided a feeding section covering the side of the coating roller away from the fixing frame.

[0013] Furthermore, the upper end of the liquid storage section is equipped with a liquid delivery section that connects to the feeding section.

[0014] Furthermore, the inner side of the fixing frame is provided with a bracket, and a fixing rod extending vertically is fixedly installed at its end, with a connecting shaft rotatably installed in its middle section.

[0015] Furthermore, both the upper and lower ends of the fixing rod are provided with ring sleeves that are fitted onto the outside of the rotating rod.

[0016] Furthermore, both ends of the fixed rod and the end of the rotating rod are provided with helical gears that mesh with each other.

[0017] This utility model has the following beneficial effects:

[0018] This invention utilizes the staggered distribution of coating rollers, combined with the rotational power transmitted by the rotary rod, to enable the coating rollers to roll on the outside of the corrugated pipe, thereby driving the corrugated pipe forward and achieving the effects of traction and support. At the same time, it avoids the pipe deformation caused by the unidirectional roller coating method.

[0019] This invention, through the staggered distribution of coating rollers, can cover the entire circumferential area of ​​the corrugated pipe. Thus, during the coating operation, the material can be coated onto each area on the outside of the corrugated pipe by rolling, achieving continuous coating operation and shortening the overall coating time.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please see Figure 1-4 As shown, this utility model is a PVC corrugated pipe surface coating device, including a corrugated pipe 110 and a fixing frame 120;

[0035] The coating unit 2 has two coating rollers 210 inside, which are distributed opposite to each other and staggered on both sides of the fixing frame 120. The outer side has an arc-shaped protrusion 211 to fill the trough of the fixing frame 120. When viewed from the front, the upper and lower ends of the adjacent coating rollers 210 overlap and intersect. At this time, the coating rollers 210 provide relative support to the corrugated pipe 110 to prevent it from deforming and sagging during coating.

[0036] The rotating rod 230 is located at both ends of the coating roller 210, perpendicular to the cross section of the coating roller 210 and extending toward the side wall of the fixed frame 120. The rotational motion drives the coating roller 210 to roll. Through the continuous rolling of the arc-shaped protrusion 211 in the trough, a thrust is applied to the bellows 110 to achieve a traction effect, causing it to move forward automatically.

[0037] Preferably, the bottom of the fixing frame 120 is provided with a liquid storage section 221, and a feeding section 220 is provided above it to cover the side of the coating roller 210 away from the fixing frame 120, so that the material can be replenished to the outer area in real time during the rolling of the coating roller 210, which facilitates continuous coating operation.

[0038] Preferably, the upper end of the liquid storage section 221 is equipped with a liquid delivery section 222 that connects to the upper, middle and lower areas outside the feeding section 220, so that the material is applied evenly to the coating roller 210.

[0039] Preferably, the inner side of the fixed frame 120 is provided with a bracket 310, and a fixed rod 320 extending vertically is fixedly installed at its end. Both the upper and lower ends of the fixed rod 320 are provided with rings 321 that are sleeved on the outside of the rotating rod 230, thereby supporting the coating roller 210. The middle section of the bracket 310 is rotatably installed with a connecting shaft 330.

[0040] Preferably, the upper and lower ends of the fixed rod 320 and the end of the rotating rod 230 are provided with helical gears that mesh with each other, thereby applying rotational power to the upper and lower ends of the coating roller 210 simultaneously, so that it is subjected to uniform force and rolls.

[0041] It is understood that this utility model does not require the coating mechanism to move circumferentially, and the coating mechanism can also traction the tube body, thereby achieving continuous coating operation and thus forming support to prevent the tube body from deforming and sagging.

[0042] A specific application of the operation process in this embodiment is as follows: First, two coating rollers 210 are arranged opposite each other and staggered inside the fixed frame 120, with their upper and lower ends overlapping. At this time, the fixed frame 120 is completely covered in a staggered manner. Then, driven by the connecting shaft 330, the rotating rod 230 drives the coating rollers 210 to rotate, thereby replacing the traction mechanism to drag the fixed frame 120. During this period, the liquid delivery unit 222 continuously delivers material to the feeding unit 220 to apply it to the coating rollers 210, thereby continuously applying mechanical coating to the fixed frame 120. In addition, the staggered distribution of the coating rollers 210 also provides mutual support to the fixed frame 120 to prevent the soft fixed frame 120 from deforming during the coating operation.
