[0002] In the existing PE pipe production and processing process, a large number of equipment are usually required, which constitute a PE pipe production line. Among these equipment, after the PE pipe production and processing is completed, relevant stacking racks are usually required for stacking, and most of the common stacking racks have a high height. In the process of stacking the pipes that have completed the production and processing, most of them first fill the bottom of the stacking rack before stacking the pipes at the high place of the stacking rack, and the common stacking rack stacking method for pipes is mostly manual stacking of the pipes by the staff. When manually stacking the pipes at the high place of the stacking rack, due to factors such as the length or size of the pipes, it is inevitable that there will be inconvenience in operation or accidents, which makes it easy to spend more time when stacking the pipes at the high place of the stacking rack, resulting in the common stacking racks having no good pipe stacking measures at the high place, which seriously affects the efficiency of pipe stacking on the stacking rack.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0027] like Figure 1-5 As shown, the present invention provides a technical solution: a PE pipe production line, comprising a stacking rack 1, a feeding mechanism 2 is arranged on one side of the stacking rack 1, the feeding mechanism 2 comprises a feeding plate 21 arranged on one side of the stacking rack 1, a rotating drum 22 is arranged on one side of the feeding plate 21, a power-assisting mechanism 23 is arranged on one side of the rotating drum 22, a feeding rack 24 is arranged on the other side of the stacking rack 1, a first motor 25 is fixedly installed on one side of the feeding rack 24, a first fixing frame 26 is fixedly installed on the outer surface of the first motor 25, and the stacking rack 1 A lifting mechanism 27 is provided on the other side of the stacking rack 1, and a rotating rod 28 is fixedly connected to the output end of the first motor 25. One end of the rotating rod 28 movably penetrates one side of the loading rack 24 through the first bearing, and one end of the rotating rod 28 is fixedly connected to one side of the rotating drum 22. The rotating drum 22 is connected to the loading rack 24 by using the rotating rod 28, so that the rotating drum 22 has good supporting and rotating characteristics on one side of the stacking rack 1, reducing the probability of the rotating drum 22 falling off and being unable to rotate. A fixing mechanism 29 is provided on one side of the rotating drum 22.

[0028] In this embodiment, when loading, the pipes that have completed production and processing are placed on the loading plate 21, and the stacking rack 1 stacks the pipes in sequence from high to low. After the pipes are placed on the loading plate 21, the loading mechanism 2 is raised by the lifting mechanism 27 until the loading mechanism 2 stops moving after it rises to the specified position, and the first motor 25 is started to run. The first motor 25 uses the output end to drive the rotating rod 28 to rotate. During the rotation of the rotating rod 28, the rotating drum 22 is driven to rotate. During the rotation of the rotating drum 22, the loading plate 21 is driven to swing. During the swinging of the loading plate 21, the placed pipes are driven gradually to move in the direction of the stacking rack 1. The pipes on the loading plate 21 slide onto the power-assisting mechanism 23 as the loading plate 21 is tilted and under the influence of gravity, and slide onto the stacking rack 1 with the help of the power-assisting mechanism 23. Example

[0029] like Figure 1 and Figure 5-8As shown, the assist mechanism 23 includes an assist disk 231 arranged on one side of the rotating cylinder 22, and a support cylinder 232 is sleeved inside the assist disk 231. A through hole matching the rotating rod 28 is opened on one side of the support cylinder 232, and one side of the support cylinder 232 is fixedly connected to one side of the loading rack 24, and a slide groove matching the slider 234 is opened inside the support cylinder 232. By opening the through hole, the rotating rod 28 can pass through the support cylinder 232 normally and rotate inside the support cylinder 232. During the rotation, the support cylinder 232 is in a stationary state. By opening the slide groove, the slider 234 can slide normally inside the support cylinder 232. The outer surface of the anti-slip pad 235 contacts the inner wall of the slide groove. By setting The anti-skid pad 235 is used to increase the friction between the slider 234 and the support tube 232, thereby reducing the probability of the assisting plate 231 moving horizontally on the support tube 232. A sliding hole adapted to the sliding rod 233 is provided on one side of the slider 234. By providing the sliding hole, the slider 234 can slide on the outer surface of the sliding rod 233. The interior of the support tube 232 is fixedly connected with the sliding rod 233. The interior of the assisting plate 231 is movably sleeved with the slider 234 through the second bearing. An anti-skid pad 235 is adhered to one side of the slider 234. By setting the assisting mechanism 23, in the process of the pipe loading the stacking rack 1, the pipe gradually contacts the assisting mechanism 23 with the swing of the loading plate 21, and gradually contacts with the loading plate 21. The material plate 21 is detached and actively slides onto the stacking rack 1 with the help of the power-assisting mechanism 23, thereby reducing the probability that the pipe cannot be normally detached from the loading plate 21 and increasing the probability that the pipe can normally contact the stacking rack 1. A limiting mechanism 236 is provided on one side of the support cylinder 232. The limiting mechanism 236 includes a ring 2361 movably sleeved on the outer surface of the support cylinder 232 through a fourth bearing, a limiting rod 2362 is provided inside the support cylinder 232, and a limiting hole matched with the limiting rod 2362 is provided on one side of the slider 234. One end of the limiting rod 2362 is fixedly connected to a turntable 2364. The outer surface of the turntable 2364 is movably connected to one side of the inner wall of the support cylinder 232 through the fifth bearing. The other end of the limiting rod 2362 is fixedly connected to A connecting ring 2364 is connected, and a connecting block 2365 is fixedly connected to the outer surface of the connecting ring 2364. One end of the connecting block 2365 movably passes through one side of the inner wall of the support tube 232, and one end of the connecting block 2365 is fixedly connected to one side of the inner wall of the ring 2361. A torsion spring 2366 is welded on one side of the connecting ring 2364, and one end of the torsion spring 2366 is welded to one side of the inner wall of the support tube 232. By setting a limiting mechanism 236, a limiting hole compatible with the limiting rod 2362 is opened on the slider 234, so that the slider 234 has a good movement limiting measure inside the support tube 232, thereby avoiding the probability of displacement of the assisting disk 231 when it is fixed after moving, and improving the stability of the fixation of the assisting disk 231.

[0030] In this embodiment, before the stacking rack 1 stacks the pipes, the position of the assisting plate 231 should be adjusted according to the length of the pipes. If the length of the pipe is short, the rotating ring 2361 rotates on the outer surface of the support tube 232, and the ring 2361 uses the connecting block 2365 to drive the connecting ring 2364 to rotate. The torsion spring 2366 is affected by the rotational force and gradually changes its shape. The limiting rod 2362 gradually swings along with the rotation of the connecting ring 2364 until the limiting rod 2362 swings to correspond to the limiting hole on the slider 234, and the position of the ring 2361 after rotation is kept stationary, and the assisting plate 231 is slowly pushed to slide on the outer surface of the support tube 232 to assist During the sliding process of the disk 231, the slider 234 is driven to move. The slider 234 slides inside the support tube 232 and slides on the outer surface of the slide rod 233. The anti-skid pad 235 moves by friction on the inner wall of the support tube 232 until the assisting disk 231 is pushed to move to a position where it can contact the pipe during the feeding process. The assisting disk 231 is kept stationary after moving, and the sleeve ring 2361 that remains stationary is slowly loosened. The torsion spring 2366 is no longer affected by the rotation force and gradually restores its shape, and actively drives the connecting ring 2364 to rotate. As the connecting ring 2364 rotates, the limiting rod 2362 gradually restores its position and limits the slider 234 again. If the length of the pipe is less than the length of the rotating drum 22, the assisting disk 231 does not need to be adjusted. During the assisting process, as the feeding mechanism 2 feeds the pipe, the pipe actively slides due to the influence of the inclination of the feeding plate 21 and gravity, and contacts the assisting plate 231. Since the assisting plate 231 and the slider 234 are connected via a second bearing, when the pipe slides and contacts the assisting plate 231, the assisting plate 231 actively rotates due to the influence of the force of the movement of the pipe, and assists the pipe to slide toward the stacking rack 1. Example

[0031] like Figure 1As shown, the lifting mechanism 27 includes a bottom plate 271 fixedly connected to one side of the stacking rack 1, a lifting plate 272 is provided on one side of the bottom plate 271, one side of the lifting plate 272 is fixedly connected to one side of the loading rack 24, and one side of the lifting plate 272 is provided with a threaded hole matching the thread on the threaded rod 273, and one side of the lifting plate 272 is provided with a movable hole matching the lifting rod 274, the output end of the second motor 276 movably passes through one side of the top plate 275, and the output end of the second motor 276 is fixedly connected to one end of the threaded rod 273, and by providing the threaded hole and the movable hole, the lifting plate 272 is lifted by the lifting rod 274 during the rotation of the threaded rod 273. While maintaining balance, it can actively move along with the rotation of the threaded rod 273. One side of the bottom plate 271 is movably connected to the threaded rod 273 through a third bearing. One side of the bottom plate 271 is fixedly connected to a lifting rod 274. One side of the stacking rack 1 is fixedly connected to a top plate 275. One side of the top plate 275 is fixedly installed with a second motor 276. The outer surface of the second motor 276 is fixedly sleeved with a second fixed frame 277. By setting up a lifting mechanism 27, when the stacking rack 1 stacks the pipes at a high place, the lifting mechanism 27 can be used to drive the feeding mechanism 2 to rise, so that the pipes placed on the stacking rack 1 can be normally stacked at a high place on the stacking rack 1 using the feeding mechanism 2.

[0032] In this embodiment, during lifting, after the pipe is placed on the loading plate 21, the second motor 276 is started, and the second motor 276 uses the output end to drive the threaded rod 273 to rotate. As the threaded rod 273 rotates, the lifting plate 272 actively moves and slides on the outer surface of the lifting rod 274, and drives the loading rack 24 to move. As the loading rack 24 moves, the loading mechanism 2 gradually rises and moves on one side of the stacking rack 1 until the loading mechanism 2 moves to the height at which the pipe needs to be stacked, and the operation of the second motor 276 is stopped. Example

[0033] like Figure 2-4As shown, the fixing mechanism 29 includes a protrusion 291 provided on one side of the rotating drum 22, a fixing plate 292 is provided inside the rotating drum 22, a connecting rod 293 is provided inside the rotating drum 22, a guide block 294 is fixedly connected to one side of the connecting rod 293, a guide rod 295 is fixedly connected to the inside of the rotating drum 22, a clamping rod 296 is fixedly connected to one side of the protrusion 291, a spring 297 is sleeved on the outer surface of the clamping rod 296, a limit plate 298 is fixedly sleeved on the outer surface of the clamping rod 296, and a spring 297 is provided on one side of the rotating drum 22, which is connected to the feeding plate 21. A fixing groove is provided on one side of the loading plate 21, and a fixing hole is provided on one side of the loading plate 21, and the loading plate 21 can be normally inserted into the inside of the rotating drum 22 and fixed by the fixing plate 292. A guide hole is provided on one side of the guide block 294, and a guide hole is provided on one side of the guide block 294, and a guide rod 295 is provided on one side of the guide block 294, and a good moving guide measure can be maintained by the guide rod 295 during the movement of the guide block 294, so that the connecting rod 293 can maintain a good movement inside the rotating drum 22. The movable guide feature is that one end of the clamping rod 296 slides through one side of the connecting rod 293, and a clamping groove matched with the clamping rod 296 is provided inside the rotating cylinder 22. By providing the clamping groove, the connecting rod 293 can be well fixed inside the rotating cylinder 22 with the help of the clamping rod 296. A limiting groove matched with the limiting plate 298 is provided inside the connecting rod 293. By providing the limiting groove, the limiting plate 298 can move normally inside the connecting rod 293. One end of the spring 297 is welded to one side of the inner wall of the limiting groove, and The other end of the spring 297 is welded to one side of the limit plate 298. By setting the spring 297, the spring 297 provides sufficient elastic force so that the limit plate 298 can actively restore its position with the help of the elastic force of the spring 297 after moving. By setting the fixing mechanism 29, the loading plate 21 and the rotating drum 22 can be disassembled and assembled, so that the loading mechanism 2 can load pipes of different sizes, thereby avoiding the phenomenon that the stacking efficiency of the stacking rack 1 is low due to the different size of the loading plate 21 and the pipe, thereby improving the efficiency of the stacking rack 1 in stacking pipes.

[0034] In this embodiment, when replacing, first replace the loading plate 21 according to the size of the stacked pipes to ensure that the loading plate 21 matches the pipes stacked on the stacking rack 1 to avoid the phenomenon of pipes falling off when the loading plate 21 is smaller than the loading plate 21. Pull the protrusion 291 to move, and the protrusion 291 drives the clamping rod 296 to slide inside the connecting rod 293. The clamping rod 296 gradually moves out of the clamping groove inside the rotating drum 22. During the movement of the clamping rod 296, it actively drives the limit plate 298 to move. The spring 297 is affected by the force of the movement of the limit plate 298 and gradually changes its shape until the protrusion 291 is pulled to move until it can no longer be pulled. Keep the position of the protrusion 291 stationary, and slowly drag the protrusion 291 to drive the connecting rod 293 to move inside the rotating drum 22. During the movement of the connecting rod 293, it drives the guide block 294 to slide on the outer surface of the guide rod 295 , and drives the fixed plate 292 to move, and the fixed plate 292 gradually moves out from the inside of the loading plate 21 until the dragging protrusion 291 moves to a point where it can no longer move, and keeps the position of the protrusion 291 after being dragged. Take out the loading plate 21 on the rotating drum 22, and replace it with a loading plate 21 corresponding to the size of the stacked pipes, insert the replaced loading plate 21 into the fixed groove on the rotating drum 22, and slowly push the protrusion 291 to move again until the fixed plate 292 is inserted into the replaced loading plate 21, and release the pulled protrusion 291, and the clamping rod 296 is inserted into the inside of the rotating drum 22 again with the help of the elastic force of the spring 297.

[0035] Working principle: like Figure 1-8As shown, before use, first replace the loading plate 21 according to the size of the stacked pipes to ensure that the loading plate 21 matches the pipes to be stacked on the stacking rack 1 to avoid the phenomenon that the loading plate 21 is smaller and the pipes fall during the loading process of larger pipes. Pull the protrusion 291 to move, and the protrusion 291 drives the clamping rod 296 to slide inside the connecting rod 293. The clamping rod 296 gradually moves out of the clamping groove inside the rotating drum 22. During the movement of the clamping rod 296, it actively drives the limit plate 298 to move. The spring 297 is affected by the force of the movement of the limit plate 298 and gradually changes its shape until the protrusion 291 is pulled to move until it can no longer be pulled. Keep the position of the protrusion 291 stationary, and slowly drag the protrusion 291 to drive the connecting rod 293 to move inside the rotating drum 22. During the movement of the connecting rod 293, it drives the guide block 294 to slide on the outer surface of the guide rod 295 , and drives the fixed plate 292 to move, and the fixed plate 292 gradually moves out from the inside of the loading plate 21 until the dragging protrusion 291 moves to a point where it can no longer move, and keeps the position of the protrusion 291 after being dragged. Take out the loading plate 21 on the rotating drum 22, and replace it with a loading plate 21 corresponding to the size of the stacked pipes, insert the replaced loading plate 21 into the fixed groove on the rotating drum 22, and slowly push the protrusion 291 to move again until the fixed plate 292 is inserted into the replaced loading plate 21, and release the pulled protrusion 291, and the clamping rod 296 is inserted into the inside of the rotating drum 22 again with the help of the elastic force of the spring 297. After the loading plate 21 is replaced, before the stacking rack 1 stacks the pipes, the position of the assisting plate 231 should be adjusted according to the length of the pipes. If the length of the pipe is short, the rotating ring 2361 rotates on the outer surface of the support tube 232, and the ring 2361 uses the connecting block 2365 to drive the connecting ring 2364 to rotate. The torsion spring 2366 is affected by the rotational force and gradually changes its shape. The limiting rod 2362 gradually swings with the rotation of the connecting ring 2364 until the limiting rod 2362 swings to correspond to the limiting hole on the slider 234, and the position of the ring 2361 after rotation is kept stationary, and the assisting plate 231 is slowly pushed to slide on the outer surface of the support tube 232. During the sliding process of the assisting disc 231, the slider 234 is driven to move. The slider 234 slides inside the support tube 232 and slides on the outer surface of the slide rod 233. The anti-skid pad 235 moves by friction on the inner wall of the support tube 232 until the assisting disc 231 is pushed to move to a position where it can contact the pipe during the feeding process. The assisting disc 231 is kept stationary after moving, and the sleeve 2361 that remains stationary is slowly loosened. The torsion spring 2366 is no longer affected by the rotation force and gradually restores its shape, and actively drives the connecting ring 2364 to rotate. As the connecting ring 2364 rotates, the limiting rod 2362 gradually restores its position and limits the slider 234 again. If the length of the pipe is less than the length of the rotating drum 22, the assisting disc 231 does not need to be adjusted; When in use, the pipes that have completed production and processing are placed on the loading plate 21, and the stacking rack 1 stacks the pipes in sequence from high to low. After the pipes are placed on the loading plate 21, the loading mechanism 2 is raised by the lifting mechanism 27, and the second motor 276 is started to operate. The second motor 276 uses the output end to drive the threaded rod 273 to rotate. As the threaded rod 273 rotates, the lifting plate 272 actively moves and slides on the outer surface of the lifting rod 274, and drives the loading rack 24 to move. As the loading rack 24 moves, the loading mechanism 2 gradually rises and moves on one side of the stacking rack 1 until the loading mechanism 2 moves to the height at which the pipes need to be stacked, the second motor 276 is stopped, and the first motor 25 is started. The first motor 25 uses the output end to drive the rotating rod 28 to rotate. During the rotation of the rotating rod 28, the rotating rod 28 drives the rotating rod 28 to rotate. The drum 22 rotates, and during the rotation of the rotating drum 22, the loading plate 21 is driven to swing. During the swinging of the loading plate 21, the placed pipes are driven to gradually move in the direction of the stacking rack 1. The pipes on the loading plate 21 slide onto the power-assisting mechanism 23 as the loading plate 21 is tilted and the influence of gravity, and slide to the stacking rack 1 with the help of the power-assisting mechanism 23. As the loading mechanism 2 loads the pipes, the pipes are actively slid by the influence of the tilt and gravity of the loading plate 21, and contact the power-assisting disk 231. Since the power-assisting disk 231 and the slider 234 are connected by the second bearing, when the pipes slide to contact the power-assisting disk 231, the power-assisting disk 231 is actively rotated by the force of the movement of the pipes, and assists the pipes to slide in the direction of the stacking rack 1 until the pipes slide to the stacking rack 1 and the pipes are stacked.
