Abstract
Description
Technical Field
[0001] This utility model relates to a correction device for PVC pipe traction processing, belonging to the field of PVC pipe processing technology. Background Technology
[0002] PVC pipes are plastic pipes made primarily of polyvinyl chloride resin through an extrusion molding process. They possess advantages such as corrosion resistance, light weight, good insulation, and low fluid resistance, and are widely used in building water supply and drainage, power and communication, and agricultural irrigation. During the PVC pipe traction processing, factors such as extrusion speed, cooling shrinkage, and uneven traction force can easily cause the pipes to deviate, thus requiring correction operations.
[0003] Authorization announcement number (CN 212666645 U) discloses a traction device for PVC pipe processing, including: a traction box, four adjustable traction rollers are installed inside the traction box, multiple traction wheels are set on the traction rollers, and a traction belt is connected between the traction wheels. Multiple mounting strips are also installed inside the traction box, and multiple adjustable extrusion rollers are set on the mounting strips. A drive motor for driving the traction rollers is fixedly installed on the traction box. Multiple inlet and outlet ports are opened on both the front and rear sides of the traction box. When the pipe is tractioned, the extrusion rollers are used to extrude on both sides of the pipe, so that the pipe is evenly stressed around its perimeter, avoiding deformation and damage to the pipe due to uneven stress.
[0004] However, the above technology cannot detect the bent parts during use, which makes it difficult to carry out subsequent correction. In subsequent processing, the pipe will have quality defects such as uneven thickness and elliptical deformation, which seriously affects the dimensional accuracy and mechanical strength of the product. Uncorrected bending will continue to be transmitted to subsequent processes, causing the straightness of the finished pipe after cooling and shaping to exceed the standard.
[0005] To address this, a correction device for PVC pipe traction processing is proposed. Utility Model Content
[0006] In view of this, the present invention provides a correction device for PVC pipe traction processing to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.
[0007] The technical solution of this utility model is implemented as follows: A PVC pipe traction processing correction device includes an operating table. A cavity is formed on the inner side of the operating table. Multiple equidistantly distributed electric conveying rollers are fixedly installed inside the cavity. Each electric conveying roller has a drive assembly inside, which can drive the electric conveying rollers to rotate. A correction mechanism is provided on the inner side of the operating table. The correction mechanism includes a connecting frame, a cylinder, sleeves, a pressure detector, an elastic electromagnetic coil, an electromagnetic gasket, a connecting rod, a connecting block, and a guide wheel. The connecting frame is located on the front and rear sides of the operating table. Multiple sleeves are fixedly connected to the inner sides of two connecting frames and are equidistantly distributed along the horizontal direction of the connecting frame surface. The pressure detector is fixedly connected to the outer side of the multiple sleeves, and the elastic electromagnetic coil is fixedly connected to the inner side of the multiple sleeves, and the elastic electromagnetic coil is electrically connected to the pressure detector.
[0008] More preferably, the connecting rod is fixedly connected to the inner side of the electromagnetic pad, the connecting block is fixedly connected to the inner side of the connecting rod, and the guide wheel is movably connected to the inner side of the connecting block via a rotating shaft.
[0009] More preferably, the electromagnetic gasket is fixedly connected to the end of the elastic electromagnetic coil away from the pressure detector, and the electromagnetic gasket slides on the inner side of the sleeve.
[0010] More preferably, the cylinders are fixedly connected to the front and rear sides of the connecting frame, and the output ends of the four cylinders pass through the operating table and are fixedly connected to the outside of the connecting frame.
[0011] More preferably, limit grooves are provided on both the left and right sides of the operating table surface, and the connecting frame is slidably connected to the inner side of the limit grooves.
[0012] More preferably, limit blocks are fixedly installed on both the left and right sides of the two connecting frames, and the size of the limit blocks is larger than the size of the limit grooves.
[0013] The present invention has the following advantages due to the adoption of the above technical solution:
[0014] I. This utility model, through the setting of the correction mechanism, if there are bending protrusions on the surface of the pipe, the protrusions will squeeze the guide wheel. After the guide wheel is squeezed, it will drive the connecting block and connecting rod to move outward and squeeze the elastic electromagnetic ring. After the elastic electromagnetic ring is squeezed, it will transmit the pressure to the pressure detector, which will analyze the pressure to detect the degree of bending, thus facilitating subsequent operations.
[0015] Second, the present invention can play a guiding role by setting the limiting groove to ensure that the connecting frame moves along the predetermined trajectory. The limiting block can play a limiting role to prevent the connecting frame from leaving the inner side of the limiting groove.
[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0025] Example 1
[0026] like Figure 1-4As shown, this utility model embodiment provides a PVC pipe traction processing correction device, including an operating table 1. A cavity 2 is formed on the inner side of the operating table 1. Multiple equidistantly distributed electric conveying rollers 3 are fixedly installed inside the cavity 2. Each electric conveying roller 3 has a drive assembly inside, which can drive the electric conveying rollers 3 to rotate. A correction mechanism 4 is provided inside the operating table 1. The correction mechanism 4 includes a connecting frame 401, a cylinder 402, a sleeve 403, a pressure detector 404, an elastic electromagnetic coil 405, an electromagnetic gasket 406, a connecting rod 407, a connecting block 408, and a guide wheel 409. The connecting frames 401 are located on the front and rear sides of the operating table 1. Multiple sleeves 403 are fixedly connected to the inner sides of the two connecting frames 401. The components are arranged equidistantly in a horizontal direction. Pressure detectors 404 are fixedly connected to the outside of multiple sleeves 403. Elastic electromagnetic coils 405 are fixedly connected to the inside of multiple sleeves 403 and are electrically connected to pressure detectors 404. Connecting rods 407 are fixedly connected to the inside of electromagnetic pads 406. Connecting blocks 408 are fixedly connected to the inside of connecting rods 407. Guide wheels 409 are movably connected to the inside of connecting blocks 408 via a rotating shaft. Electromagnetic pads 406 are fixedly connected to the end of elastic electromagnetic coils 405 away from pressure detectors 404 and slide on the inside of sleeves 403. Cylinders 402 are fixedly connected to the front and rear sides of connecting frame 401. The output ends of the four cylinders 402 pass through the operating table 1 and are fixedly connected to the outside of connecting frame 401.
[0027] With the setting of the correction mechanism 4, if there are bending protrusions on the surface of the pipe, the protrusions will squeeze the guide wheel 409. After being squeezed, the guide wheel 409 will drive the connecting block 408 and the connecting rod 407 to move outward and squeeze the elastic electromagnetic ring 405. After being squeezed, the elastic electromagnetic ring 405 will transmit the pressure to the pressure detector 404. The pressure detector 404 will analyze the pressure to detect the degree of bending, which will facilitate subsequent operations.
[0028] Example 2
[0029] In one embodiment, limit grooves 5 are provided on both the left and right sides of the surface of the operating table 1, and the connecting frame 401 is slidably connected to the inner side of the limit groove 5. Limit blocks 6 are fixedly installed on both the left and right sides of the two connecting frames 401, and the size of the limit block 6 is larger than the size of the limit groove 5.
[0030] The limiting groove 5 serves as a guide to ensure that the connecting frame 401 moves along a predetermined trajectory. The limiting block 6 serves as a limit to prevent the connecting frame 401 from dislodging from the inside of the limiting groove 5.
[0031] In operation, this invention works as follows: After placing the PVC pipe on top of the electric conveyor roller 3, the electric conveyor roller 3 can be started to rotate. Simultaneously, the rotation of the electric conveyor roller 3 drives the pipe forward. At this time, two cylinders 402 can be activated to move the connecting frame 401 at the output end inward. During the movement of the connecting frame 401, the sleeve 403 moves inward. The movement of the sleeve 403 causes the inner elastic electromagnetic ring 405, electromagnetic pad 406, connecting rod 407, connecting block 408, and guide wheel 409 to move inward, making the guide wheel 409 fit against the pipe. When the pipe passes through the electric... When the conveying roller 3 passes through the inside of the guide wheel 409, if there are bends or protrusions on the surface of the pipe, the protrusions will squeeze the guide wheel 409. After being squeezed, the guide wheel 409 will move outward, driving the connecting block 408 and the connecting rod 407 to move outward. At the same time, the connecting rod 407 will drive the electromagnetic pad 406 to move outward, squeezing the elastic electromagnetic ring 405. After being squeezed, the elastic electromagnetic ring 405 will transmit the pressure to the pressure detector 404. The pressure detector 404 will analyze the pressure to detect the degree of bend, which will facilitate subsequent operations.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
