DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0020] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of HDPE double-wall corrugated pipe spraying device, including support 1, servo motor 2, bottom roller 3, electric telescopic rod 4, positioning roller 5, back plate 6, track window 7, movable plate 8, horizontal roller 9, top plate 10, rotating shaft 11, spraying pipe 12, locking bolt 13, locking nut 14, limiting window 15, curing mechanism 16, drying pipe 17 and nozzle 18, support 1 one side bottom is fixed with servo motor 2, the output end of servo motor 2 is installed with bottom roller 3, bottom roller 3 is rotatably installed in support 1 inner bottom, support 1 top end is fixedly installed with electric telescopic rod 4, electric telescopic rod 4 bottom end is installed with positioning roller 5, support 1 rear side is fixedly installed with back plate 6, back plate 6 center is penetrated and is equipped with track window 7, back plate 6 is installed with movable plate 8, movable plate 8 inner bottom rotatably installs with horizontal roller 9, horizontal roller 9 is inlaid with track window 7, movable plate 8 outer side top is fixedly installed with top plate 10, top plate 10 inner side is rotatably installed with spraying pipe 12 by rotating shaft 11, spraying pipe 12 one end side surface is fixedly installed with locking bolt 13, locking bolt 13 end is installed with locking nut 14, locking bolt 13 penetrates limiting window 15, limiting window 15 is equipped on top plate 10, movable plate 8 front side surface middle part is installed with curing mechanism 16, movable plate 8 front side surface bottom is fixedly installed with drying pipe 17, drying pipe 17 front end is installed with nozzle 18.
[0021] The bottom roller 3 of the example is symmetrically distributed about the positioning roller 5, the diameter of the bottom roller 3 is greater than the diameter of the positioning roller 5, and the above-mentioned structure design can stably position and drive corrugated pipes of different diameters, ensuring the stability of the corrugated pipe during the spraying process.
[0022] The length of the track window 7 is not less than the length of the bottom roller 3, and the height of the track window 7 is higher than the top end of the bottom roller 3, and the above-mentioned structure design ensures that the working height and horizontal working range of the horizontal roller 9 and the movable plate 8 connected with the track window 7 are sufficient.
[0023] The side view shape of the movable plate 8 is an inverted "U" shape, and the inner side surface of the movable plate 8 is fitted with the surface of the back plate 6. The above structural design makes the movable plate 8 not separate from the back plate 6 and can only move horizontally in a straight line along the back plate 6.
[0024] The top plate 10, the spraying pipe 12, the locking bolts 13 and the locking nuts 14 are all symmetrically distributed about the center of the movable plate 8. The locking bolts 13 are slidably connected to the limiting windows
[0028] 15. The above structural design enables the spraying pipe 12 to stably rotate and adjust with the rotating shaft 11 as the center, so that the spraying pipe 12 can carry the locking bolts 13 and slide stably along the limiting windows 15.
[0025] The limiting windows 15 are set to be arc-shaped, and the center of the circle where the arc side of the limiting windows 15 is located coincides with the center of the rotating shaft 11. The above structural design ensures that the locking bolts 13 can slide stably within the limiting windows 15 and ensures the stability of the spraying pipe 12 during the adjustment process.
[0026] Working principle: When using this device, first move the HDPE double-wall corrugated pipe to be sprayed onto the symmetrically distributed bottom rollers 3, control the electric telescopic rods 4 at the top of both ends of the bracket 1 to extend synchronously, and push the positioning rollers 5 downward to contact the top of the corrugated pipe for positioning the corrugated pipe; <##
[0027] Then,拨动 is translated as "拨动" in Chinese, which is an incorrect or non-standard term. Assuming it should be "rotate", rotate the spraying pipe 12 to rotate with the rotating shaft 11 as the center. The spraying pipe 12 carries the locking bolts 13 and slides along the limiting windows 15 to adjust the pitching angle until the working angle of the spraying pipe 12 is appropriate. Rotate the locking nuts 14 installed at the ends of the symmetrically distributed locking bolts 13 to squeeze and fix the top plate 10. Start the paint supply mechanism or polyethylene powder supply mechanism connected to the spraying pipe 12, and spray the paint or polyethylene powder on the corrugated pipe;
[0028] At the same time, control Figure 2 The servo motors 2 connected to the symmetrically distributed bottom rollers 3 in the Figure 2 , drive the two bottom rollers 3 to slowly rotate counterclockwise synchronously. The bottom rollers 3 use friction to drive the corrugated pipe placed on them to slowly rotate clockwise. The outer wall part of the corrugated pipe sprayed by the spraying pipe 12 rotates counterclockwise and moves towards the curing mechanism 16 and the drying pipe 17. At the same time, the spraying pipe 12 also sprays the surface of the unsprayed corrugated pipe rotated to the position opposite to it. The curing mechanism 16 works to cure the polyethylene powder, and the air pump connected to the drying pipe 17 sprays the gas from the nozzle 18 to quickly dry the paint;
[0029] Until the entire outer wall of the corrugated pipe opposite to the spraying pipe 12 is sprayed, move the movable plate 8 to carry the horizontal roller 9 and move horizontally along the back plate 6 and the track window 7 to change the horizontal spraying position, and repeat the above steps to achieve continuous and uniform spraying of the outer wall of the HDPE double-wall corrugated pipe. This is the working principle of this HDPE double-wall corrugated pipe spraying device. It should be noted that there seems to be an incorrect or non-standard term "拨动" in the original text. I have made an assumption for translation based on the context, but it may need further clarification in the original content.
[0030] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
