[0020] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 6-8 ,

[0022] A corrugated pipe production device includes a fixed frame 101, two positioning rollers 102 are rotatably connected to the fixed frame 101 through bearings, two sliding rods 202 are slidably connected to the fixed frame 101, brackets 201 are welded to the two sliding rods 202, contact balls 204 are rotatably connected to the brackets 201 through bearings, a scraper 206 is welded to the bracket 201, a baffle is provided at the end of the sliding rod 202, a spring 203 is sleeved on the sliding rod 202, and the spring 203 is located between the baffle and the fixed frame 101.

[0023] When using the production device, the staff first transfers the newly formed corrugated tube through the fixed frame 101, so that the corrugated tube passes between the two positioning rollers 102. The two positioning rollers 102 play the role of positioning the corrugated tube, which can ensure the horizontal movement of the corrugated tube. At the same time, the curve of the positioning roller 102 itself can prevent the corrugated tube from deforming. When the corrugated tube passes through the two positioning rollers 102, its edge can come into contact with the two contact balls 204. With the cooperation of the slide bar 202 and the spring 203, the contact ball 204 has telescopic performance. When the contact ball 204 comes into contact with the texture of the corrugated tube, the contact ball 204 can enter the texture of the corrugated tube, thereby being able to produce an automatic telescopic movement along the texture of the corrugated tube. At the same time, the scraper 206 moves with the bracket 201, and can then scrape off the waste material on the edge of the corrugated tube, making both sides of the corrugated tube smoother, thereby reducing the risk of the corrugated tube breaking due to wear.

[0024] The contact ball 204 can rotate when in contact with the surface of the bellows, and the contact ball 204 automatically reduces friction, thereby avoiding friction damage to the outer wall of the bellows.

[0025] See also Figure 7 ,

[0026] Both contact balls 204 are hollow structures. Both contact balls 204 are provided with a plurality of drainage holes 205 . Both upper ends of the two contact balls 204 are provided with connecting pipes 301 .

[0027] During the rotation of the contact ball 204, cold water is introduced into the contact ball 204 through the connecting pipe 301 and is sprayed out through multiple drainage holes 205. Under the rotation of the contact ball 204, the cold water can be evenly sprayed onto the surface of the bellows, thereby cooling the bellows and avoiding deformation of the bellows. At the same time, the rotating cold water promotes the discharge of scraped waste under the action of the impact force, thereby avoiding waste accumulation and affecting the scraping effect of the waste.

[0028] See also Figure 4 ,

[0029] The upper end of the fixing frame 101 is fixedly connected with a water tank 303 by bolts, and two hoses 302 are fixedly connected to the water tank 303. The two hoses 302 are rotatably connected to the two connecting pipes 301 respectively by bearings.

[0030] The water tank 303 is used to store cold water. The cold water is passed into the two connecting pipes 301 through the two hoses 302 and finally reaches the two contact balls 204, thereby realizing the function of spraying cold water.

[0031] See also Figure 1-5 ,

[0032] A water supply pipe 501 is welded to the water tank 303 , a sliding plug 404 is slidably connected to the water supply pipe 501 , a water inlet pipe 502 is fixedly connected to the water supply pipe 501 , and one-way valves are installed in the water inlet pipe 502 and the two hoses 302 .

[0033] When the sliding plug 404 slides into the water supply pipe 501, the pressure in the water supply pipe 501 increases. At this time, the one-way valve in the water inlet pipe 502 is closed, and the one-way valves in the two hoses 302 are opened. At this time, cold water is discharged. When the sliding plug 404 slides outward, negative pressure is generated in the water supply pipe 501, the one-way valve in the water inlet pipe 502 is opened, and the one-way valves in the two hoses 302 are closed. At this time, cold water can be sucked in through the water inlet pipe 502, thereby realizing the function of automatically replenishing cold water.

[0034] See also Figure 4-5 ,

[0035] A pulley 401 is rotatably connected to the fixed frame 101 via a bearing, one of the positioning rollers 102 is fixedly connected to another pulley 401, and the two pulleys 401 are connected via a synchronous belt, one of the pulleys 401 is rotatably connected to an eccentric rod 402, and the eccentric rod 402 is rotatably connected to a push-pull rod 403 via a bearing, and the other end of the push-pull rod 403 is rotatably connected to a sliding plug 404.

[0036] When the bellows passes through the two positioning rollers 102, the friction force drives the two positioning rollers 102 to rotate, and then the eccentric rod 402 can be driven to rotate under the cooperation of the two pulleys 401 and the synchronous belt, and then the push-pull action of the sliding plug 404 is realized through the push-pull rod 403, so as to realize the function of intermittent spraying of cold water, realize the function of cooling the bellows and cleaning the waste, and there is no need to control the sliding plug 404 separately, which simplifies the operation and further improves the continuity of the overall process.

[0037] See also Figure 8 ,

[0038] The two positioning rollers 102 are fixedly connected with arc-shaped ridges 103, which are used to cooperate with the texture on the surface of the corrugated pipe, so that the corrugated pipe can drive the positioning rollers 102 to rotate when moving, avoiding slipping and further improving the transmission efficiency between the bellows and the positioning rollers 102.

[0039] See also Figure 1-3 ,

[0040] The production device also includes a water tank 503, into which a water inlet pipe 502 extends. The water tank 503 is used to provide a water source. When negative pressure is generated in the water supply pipe 501, cold water in the water tank 503 is drawn through the water inlet pipe 502, thereby realizing the function of automatic water replenishment.

[0041] See also Figure 1-3 ,

[0042] The discharged cold water flows back into the water storage tank 503, and the filter plate 504 plays a role in filtering the water. The discharged waste is isolated on the filter plate 504, so that it is convenient for the staff to recycle the waste.

[0043] A bellows production process, the process comprising the following steps:

[0044] Step 1: The newly formed corrugated tube is conveyed through the fixing frame 101 so that the corrugated tube passes between two positioning rollers 102;

[0045] Step 2: The contact ball 204 contacts the texture of the bellows, and the scraper 206 moves along with the bracket 201 to scrape off the waste material on the edge of the bellows;

[0046] Step 3: cold water is introduced into the contact ball 204 through the connecting pipe 301, and the cold water is sprayed out through the multiple drainage holes 205. The cold water is sprayed evenly onto the surface of the bellows to cool the bellows. The rotating cold water promotes the discharge of scraped waste under the action of impact force.

[0047] Step 4: Filter the discharged water using the filter plate 504;

[0048] Step 5: Recycle the waste.

[0049] A corrugated pipe comprises 60 parts of polypropylene, 0.3 parts of antioxidant, 0.4 parts of light stabilizer and 0.3 parts of lubricant.
