[0002] CPVC pipes are a kind of high-performance thermoplastic pipes, mainly used for the protection of wires and cables, especially in environments that need to withstand high temperature and high pressure. Generally, several CPVC pipes are stacked and packaged together. During the stacking process of CPVC pipes, a turnover rack is required.

[0003] A Chinese patent with the authorization announcement number CN 204322469 U discloses an automatic turnover and storage rack for pipes, which mainly includes a base, a lifting screw rod, a lifting nut sleeve, a support, a V-shaped bracket, a turnover cylinder, a transfer and storage bracket, and a bracket cylinder. The lifting nut sleeve is movably installed on the base, and the support is fixedly installed at the upper end of the lifting screw rod. The lower end of the lifting screw rod is screwed into the lifting nut sleeve. The V-shaped bracket is placed on the support, and both ends of the turnover cylinder are movably connected to the base and the V-shaped bracket respectively. The upper end of the transfer and storage bracket is movably connected to the support, and its lower end is movably connected to the upper end of the bracket cylinder. The lower end of the bracket cylinder is movably connected to the base through a connecting rod. The advantages of the utility model are: simple structure and very reasonable design, which not only effectively guarantees the product quality, but also effectively controls the production cost of the product.

[0004] During the process of turning over and stacking CPVC pipes by the existing turnover rack, since the pipe supporting structure on the turnover rack is a fixed structure and cannot be adjusted in size according to the size and quantity of CPVC pipes, the adjustability of the device is poor. Therefore, a CPVC pipe production turnover rack is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems existing in the prior art, the utility model proposes a CPVC pipe production turnover rack.

[0006] The technical solution adopted by the present utility model to solve its technical problems is a CPVC pipe production turnover rack, including a footrest. Two support rods are installed on the footrest. Two connecting rods are installed on the two support rods. Two first guide plates are symmetrically installed on the two support rods. A first guide groove is formed in the first guide plate. A first guide block is assembled in the first guide groove. A first lead screw is rotatably installed on the inner wall of one of the first guide grooves. A first knob is welded to the top side of the first lead screw. A first lifting rod is fixedly installed between the two first guide blocks. Two second guide plates are symmetrically installed on the two support rods. A second guide groove is formed in the second guide plate. A second guide block is assembled in the second guide groove. A second lead screw is rotatably installed on the inner wall of one of the second guide grooves. A second knob is welded to the top side of the second lead screw. A second lifting rod is fixedly installed between the two second guide blocks. A plurality of support rods are installed on the second lifting rod and the first lifting rod. A plurality of material blocking rods are installed on the side wall of the connecting rod. A connecting groove is formed in the inner wall of the material blocking rod. A connecting block is assembled in the connecting groove. The connecting block is fixedly connected to the side wall of the support rod. By driving the support rods on the first lifting rod and the second lifting rod to move vertically downward, the material supporting space between the support rods and the material blocking rods is increased. When the size of the CPVC pipes to be placed is larger or the number of CPVC pipes is larger, the space of the material supporting structure can be adjusted as needed, which is beneficial to improving the adjustability of the device.

[0007] Preferably, an installation rod is fixedly installed on the second guide plate. A turnover plate is rotatably installed on the installation rod through a hinge.

Two fixing blocks are installed on the connecting rod. A hydraulic cylinder is rotatably installed on the fixing block through a pin. A hydraulic rod is installed on the hydraulic cylinder. The hydraulic rod is rotatably connected to the side wall of the turnover plate through a pin. By pushing one end of the long CPVC pipe onto the turnover plate for feeding, during this process, due to the installation of rollers on the turnover plate, the friction between the CPVC pipe and the rollers is small, and the feeding speed of the CPVC pipe is fast, which is beneficial to improving the feeding efficiency of the CPVC pipe.

[0008] The beneficial effects of the present utility model are as follows:

[0009] 1. In the present utility model, by driving the support rods on the first lifting rod and the second lifting rod to move vertically downward, the material supporting space between the support rods and the material blocking rods is increased. When the size of the CPVC pipes to be placed is larger or the number of CPVC pipes is larger, the space of the material supporting structure can be adjusted as needed, which is beneficial to improving the adjustability of the device.

[0010] 2. The utility model feeds materials by pushing one end of a long CPVC pipe onto the turning plate. During this process, rollers are installed on the turning plate, and the friction between the CPVC pipe and the rollers is small, so the feeding speed of the CPVC pipe is fast, which is beneficial to improving the feeding efficiency of the CPVC pipe.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-3As shown in the figure, a turnover rack for CPVC pipe production includes a footrest 1. Two support rods 2 are installed on the footrest 1. Two connecting rods 3 are installed on the two support rods 2. Two first guide plates 4 are symmetrically installed on the two support rods 2. A first guide groove 5 is formed in the first guide plate 4. A first guide block 6 is assembled in the first guide groove 5. A first lead screw 7 is rotatably installed on the inner wall of one of the first guide grooves 5. A first knob 8 is welded to the top side of the first lead screw 7. A first lifting rod 9 is fixedly installed between the two first guide blocks 6. Two second guide plates 10 are symmetrically installed on the two support rods 2. A second guide groove 11 is formed in the second guide plate 10. A second guide block 12 is assembled in the second guide groove 11. A second lead screw 13 is rotatably installed on the inner wall of one of the second guide grooves 11. A second knob 14 is welded to the top side of the second lead screw 13. A second lifting rod 15 is fixedly installed between the two second guide blocks 12. A plurality of support rods 16 are installed on the second lifting rod 15 and the first lifting rod 9. A plurality of material retaining rods 17 are installed on the side wall of the connecting rod 3. A connecting groove 18 is formed in the inner wall of the material retaining rod 17. A connecting block 19 is assembled in the connecting groove 18. The connecting block 19 is fixedly connected to the side wall of the support rod 16. During operation, in the process of turning and stacking the CPVC pipe 27 by the existing turnover rack, since the material supporting structure on the turnover rack is a fixed structure and cannot be adjusted in size according to the size and quantity of the CPVC pipe 27, the adjustability of the device is poor. By rotating the first knob 8, the first lead screw 7 is driven to rotate. The first lead screw 7 drives the first guide block 6 on it to move vertically downward. The first guide block 6 drives the first lifting rod 9 to move vertically downward. At the same time, the second knob 14 is rotated to drive the second lead screw 13 to rotate. The second lead screw 13 drives the second guide block 12 on it to move vertically downward. The second guide block 12 drives the second lifting rod 15 to move vertically downward. The first lifting rod 9 and the second lifting rod 15 drive the support rods 16 on them to move vertically downward, and the material supporting space between the support rods 16 and the material retaining rods 17 increases. When the size of the CPVC pipe 27 to be placed is large or the quantity of the CPVC pipe 27 is large, the space of the material supporting structure is adjusted according to the need, which is beneficial to improving the adjustability of the device.

[0020] Please refer to Figures 4-5As shown in the figure, an installation rod 20 is fixedly installed on the second guide plate 10. A turnover plate 21 is rotatably installed on the installation rod 20 through a hinge. Assembly grooves 22 are symmetrically formed on the side wall of the turnover plate 21. A plurality of rollers 23 are rotatably installed on the inner wall of the assembly groove 22. A CPVC pipe 27 is placed on the rollers 23. Two fixing blocks 24 are installed on the connecting rod 3. A hydraulic cylinder 25 is rotatably installed on the fixing block 24 through a pin. A hydraulic rod 26 is installed on the hydraulic cylinder 25. The hydraulic rod 26 is rotatably connected to the side wall of the turnover plate 21 through a pin. During operation, when the existing turnover rack turns and stacks the CPVC pipes 27, the CPVC pipes 27 are fed onto the turnover plate 21 by horizontal movement. Due to the friction between the turnover plate 21 and the CPVC pipes 27, the feeding efficiency of the CPVC pipes 27 is relatively low. By placing one end of the long CPVC pipe 27 on the turnover plate 21 and cutting the CPVC pipe 27, through the operation of the hydraulic cylinder 25, the hydraulic rod 26 moves downward and pulls the turnover plate 21 to turn. The cut CPVC pipe 27 on the turnover plate 21 moves onto the support rod 16. Then, one end of the long CPVC pipe 27 is continuously pushed onto the turnover plate 21 for feeding. During this process, due to the installation of the rollers 23 on the turnover plate 21, the friction between the CPVC pipe 27 and the rollers 23 is small, and the feeding speed of the CPVC pipe 27 is fast, which is beneficial to improving the feeding efficiency of the CPVC pipe 27.

[0021] Working principle: During the process of flipping and stacking CPVC pipes 27 by the existing pipe turning rack, since the material supporting structure on the pipe turning rack is a fixed structure and cannot be adjusted in size according to the size and quantity of the CPVC pipes 27, the adjustability of the device is poor. By rotating the first knob 8, the first lead screw 7 is driven to rotate. The first lead screw 7 drives the first guide block 6 thereon to move vertically downward. The first guide block 6 drives the first lifting rod 9 to move vertically downward. At the same time, rotate the second knob 14 to drive the second lead screw 13 to rotate. The second lead screw 13 drives the second guide block 12 thereon to move vertically downward. The second guide block 12 drives the second lifting rod 15 to move vertically downward. The first lifting rod 9 and the second lifting rod 15 drive the supporting rod 16 thereon to move vertically downward, and the material supporting space between the supporting rod 16 and the material blocking rod 17 increases. When the size of the CPVC pipes 27 to be placed is larger or the quantity of the CPVC pipes 27 is more, adjust the space of the material supporting structure as needed, which is beneficial to improving the adjustability of the device. When the existing pipe turning rack flips and stacks the CPVC pipes 27, the CPVC pipes 27 are fed onto the turning plate 21 by horizontal movement. Due to the friction between the turning plate 21 and the CPVC pipes 27, the feeding efficiency of the CPVC pipes 27 is low. By placing one end of the long CPVC pipe 27 on the turning plate 21 and cutting the CPVC pipe 27, through the operation of the hydraulic cylinder 25, the hydraulic rod 26 moves downward and pulls the turning plate 21 to turn over. The CPVC pipe 27 cut on the turning plate 21 moves onto the supporting rod 16. Then, one end of the long CPVC pipe 27 is continuously pushed onto the turning plate 21 for feeding. During this process, by installing rollers 23 on the turning plate 21, the friction between the CPVC pipes 27 and the rollers 23 is small, and the feeding speed of the CPVC pipes 27 is fast, which is beneficial to improving the feeding efficiency of the CPVC pipes 27.
