[0002] During the production process of plastic pipes, sometimes it is necessary to correct the plastic pipes to improve the production quality of the plastic pipes. Therefore, a shape correction device for plastic pipe production is required.

[0003] For example, a shape correction device for plastic pipe production with a patent publication number of CN219650555U can drive two moving nuts to move towards each other by rotating a bidirectional lead screw through a set adjustment mechanism, and then drive a connecting rod to move by the movement of the moving nuts.

[0004] However, during the actual use of the above-mentioned shape correction devices, due to the different styles of plastic pipes, when correcting plastic pipes with a curvature, the device cannot well adapt to the shape of the plastic pipes, and workers need to make multiple adjustments, which reduces the applicability of the device and also reduces the correction rate of the plastic pipes. Therefore, the applicant proposes a shape correction device for plastic pipe production. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] During the production process of plastic pipes, when cooling them, the plastic pipes will expand and contract due to heat, which may cause the plastic pipes to deform. In order to improve the quality of plastic pipe production, it is necessary to correct the plastic pipes. Therefore, an outer shape correction device for plastic pipe production is required. In the actual use of most traditional outer shape correction devices, due to the different curvatures of plastic pipes, when dealing with plastic pipes with a curvature, workers need to continuously adjust the device. Because the inner diameters of the pipes are different, different sizes of correction devices need to be replaced, which reduces the applicability of the device and also reduces the correction rate of the pipes. For this reason, the applicant proposes an outer shape correction device for plastic pipe production.

[0022] As Figures 1 - 4As shown in the figure, the utility model provides a technical solution: an outer shape correction device for plastic pipe production, including a correction moving base 1. One end of the top of the correction moving base 1 is fixed with a correction mechanism 2. The correction mechanism 2 includes a chute ring 201. One side of the outer wall of the chute ring 201 is fixed with a fixed plate 202. A movable plate 203 is slidably connected to the groove wall of the chute ring 201. Hoop 204 is respectively fixed to the tops of the fixed plate 202 and the movable plate 203. One side of the fixed plate 202 is fixed with a fixed frame 205. Several air bags 206 are fixed to one side of the inner wall of the fixed frame 205. A universal telescopic tube 207 is fixed between adjacent air bags 206. A control mechanism 3 is fixed to the top of the correction moving base 1. The top of the control mechanism 3 is fixed to the bottom of the correction mechanism 2. The correction mechanism 2 is located at the center of the top of the control mechanism 3. One side of the outer wall of the fixed frame 205 is fixed with a stabilizing frame 208. An air pump 209 is fixed to the bottom of the inner wall of the stabilizing frame 208. After the exhaust end of the air pump 209 penetrates through one side of the outer wall of the fixed frame 205, it is fixed to one end of the outermost air bag 206. A scale ring 210 is fixed to the outer wall of the chute ring 201. The scale ring 210 does not interfere with the fixed plate 202. The sum of the minimum lengths of several air bags 206 and several universal telescopic tubes 207 should be less than or equal to the length of the fixed frame 205, and the sum of their maximum lengths should be greater than the diameter of the chute ring 201. The air pump 209, the air bags 206 and the universal telescopic tubes 207 are connected in sequence. The air pump 209 and the motor 304 are electrically connected in sequence, and the two share a control terminal.

[0023] It should be noted that when correcting the plastic pipe, first push the correction moving base 1 to the corresponding position. Then, the control mechanism 3 will control the movable plate 203 to move to the corresponding scale on the scale ring 210. Subsequently, one end of the pipe is inserted into the hoop 204 on the fixed plate 202 through the hoop 204 on the movable plate 203. Then, several air bags 206 and several universal telescopic tubes 207 are extended into the inner wall of the pipe. Then, the two hoops 204 are fixed. Next, the air pump 209 will start. At this time, under the action of the air pump 209, the air bags 206 will expand and correct the deformed part of the inner wall of the plastic pipe. When the plastic pipe itself has a curvature, under the start of the air pump 209, the universal telescopic tube 207 will change with the change of the angle of the air bag 206, so as to complete the correction of the pipe.

[0024] As Figure 4As shown in the figure, the present utility model provides a technical solution: an outer shape correction device for plastic pipe production, including a control mechanism 3. The control mechanism 3 includes a chassis 301. A plurality of fixed rods 302 are fixed on the top of the chassis 301. The plurality of fixed rods 302 are evenly distributed at equal angles around the center of the chassis 301. The tops of the plurality of fixed rods 302 are commonly fixed to the bottom of the sliding groove ring 201 in the correction mechanism 2. A housing 303 is fixed at the center position on the top of the chassis 301. A motor 304 is fixed to the bottom of the inner wall of the housing 303. The output end of the motor 304 penetrates through the top of the inner wall of the housing 303 and then is fixed with a rotating rod 305. A control rod 306 is fixed to the top of one end of the rotating rod 305. One side of the top of the control rod 306 is fixed to one side of the movable plate 203 in the correction mechanism 2.

[0025] It should be noted that when correcting the plastic pipe, first, the motor 304 will start and drive the rotating rod 305 to rotate. At this time, the control rod 306 will rotate synchronously under the rotation of the rotating rod 305 to adjust the movable plate 203 in the correction mechanism 2, thereby completing the correction of the pipe.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended embodiments and their equivalents.
