Description

Technical Field

[0001] The invention relates to the technical field of double-wall corrugated pipe processing, in particular to a HDPE double-wall corrugated pipe processing device and a processing method thereof. Background Art

[0002] A corrugated pipe is a wavy pipe with a regular shape. It is mainly used to connect pipes in situations where a very small bending radius is required, irregular turns are made, the pipe will expand and contract, or where it is inconvenient to install with a fixed elbow. The corrugated pipe can be bent, stretched or compressed slightly.

[0003] The following problems exist in the existing bellows processing:

[0004] (1) During the processing of the short corrugated pipe, the corrugated pipe needs to be cut. When cutting, the existing cutting equipment cannot cut the corrugated pipe properly because the pipe is thin and prone to bending and deformation.

[0005] (2) When performing the water removal operation using a bellows, it is rather troublesome to remove the water. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a HDPE double-wall corrugated pipe processing device and a processing method thereof, which solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a HDPE double-wall corrugated pipe processing device, comprising a fixed machine platform and a cutting assembly arranged above the fixed machine platform, wherein the surface of the fixed machine platform is respectively provided with a drying assembly for dewatering the corrugated pipe, a conveying assembly for conveying the corrugated pipe, and a guide assembly for assisting in cutting and discharging the corrugated pipe;

[0008] The drying component includes a ring fixed to the surface of the fixed machine and a power shaft and a take-up wheel rotatably arranged on one side of the fixed machine. The inner cavity of the ring is slidably connected to a sliding block through a slide groove, and one side of the sliding block is connected to an air blowing head, and the air blowing head is connected to an external air source. The surface of the take-up wheel is transmission-connected to a pull rope fixed to one side of the sliding block, and the surface of the power shaft is transmission-connected to the take-up wheel through a belt transmission mechanism. There are two take-up wheels and power shafts, and they are symmetrically arranged on both sides of the ring. The inner cavity of the fixed machine is fixedly connected to a driving cylinder, and one end of the piston rod of the driving cylinder is rotationally connected to a belt abutting the surface of the belt transmission mechanism. The tensioner pulley squeezes the belt drive mechanism through the movement of the tensioner pulley. After the belt is tightened, the take-up pulley can be driven to rotate through the rotation of the power shaft. When the driving cylinder is retracted, the tensioner pulley is retracted, and the belt of the belt drive mechanism loses transmission. Multiple take-up pulleys can be driven to rotate by a single power shaft. The operation is simple and easy to use. Through the setting of the take-up pulleys on both sides and the contraction of the pull rope, the take-up pulley is driven to rotate and the sliding block is driven to move, which drives the air blowing head to move and adjust the position. It can effectively blow the moisture on the corrugated pipe to the bottom for cleaning, with good dewatering effect. The position of the air blowing head can be quickly adjusted according to the size of the pipe for adaptive adjustment, and precise point-to-point water blowing.

[0009] As a further solution of the present invention: there are multiple rings and they are evenly distributed on the fixed machine. Through the arrangement of multiple rings, multiple sliding blocks drive the blowing heads to be staggered from top to bottom along the rings, forming an arc trajectory from front to back, and the blowing heads are arranged progressively.

[0010] As a further solution of the present invention: the conveying component includes a guide wheel rotatably arranged in the inner cavity of the fixed machine, and the surface of the guide wheel is provided with a guide inner groove adapted to the surface of the corrugated pipe. When the guide wheel rotates, the guide inner groove adapts to the surface of the corrugated pipe, and the corrugated pipe can be pulled to ensure that the corrugated pipe can be smoothly conveyed.

[0011] As a further solution of the present invention: the guide assembly includes a pushing cylinder fixed above the fixed machine, an air pump and a sliding sleeve slidably arranged above the fixed machine, the top of the sliding sleeve is fixedly connected to a fixed frame, the inner cavity of the fixed frame drives a push rod slidably arranged in the inner cavity of the fixed frame through a gear set, one end of the push rod is fixedly connected to an expansion airbag, the surface of the fixed frame is fixedly connected to the air cavity, the air outlet of the air pump is connected to the inner cavity of the air cavity through a connecting pipe, one side of the air cavity is connected to the inner cavity of the expansion airbag through a telescopic pipe, the piston end of the pushing cylinder is fixedly connected to one side of the sliding sleeve, and when cutting is performed through the cutting assembly During cutting, the push cylinder is started to drive the sliding sleeve to slide above the fixed machine table. After the sliding sleeve moves to the left to the limit on the fixed machine table, the gear set in the fixed frame drives the push rod to move to the left and extend to the limit, at this time driving the expansion airbag to move to the inside of the corrugated tube, and then the air pump supplies air to the air cavity, and supplies air to the expansion airbag through the telescopic pipe. The expansion airbag expands to support the inner wall of the corrugated tube, and then the cutting assembly cuts the corrugated tube at this time, which can effectively prevent deformation during cutting and make the forming quality better. The push rod and sliding sleeve have double-stroke movement and a longer stroke, which can be suitable for cutting longer pipes. After cutting, the push rod and sliding sleeve are reset.

[0012] As a further solution of the present invention: a bottom receiving plate is fixedly connected to one side of the sliding sleeve, and a guide wheel is rotatably provided on the top of the bottom receiving plate to abut against the bottom of the corrugated pipe. Through the setting of the guide wheel, the bottom receiving plate receives the bottom of the corrugated pipe, which can ensure the stability of the corrugated pipe itself during cutting.

[0013] As a further solution of the present invention: the fixed machine is provided with a discharge chute between the cutting assembly and the guide assembly. Through the setting of the discharge chute, the cut corrugated pipe can directly fall down the discharge chute and be discharged.

[0014] As a further solution of the present invention: a guide plate is fixedly connected to the top of the fixed machine, and the bottom of the guide plate abuts against the top of the corrugated tube. The guide plate is set to guide the corrugated tube downward so that the corrugated tube is tilted downward and output from the discharge chute.

[0015] The present invention also discloses a method for processing a HDPE double-wall corrugated pipe, comprising the following steps:

[0016] Step 1: The surface of the bellows is adapted by rotating the inner groove of the guide, and the bellows can be pulled to ensure that the bellows can be transported smoothly;

[0017] The second step is to squeeze the belt transmission mechanism through the movement of the tensioner pulley. After the belt is tightened, the take-up wheel can be driven to rotate by the rotation of the power shaft. When the driving cylinder is retracted, the tensioner pulley is retracted, and the belt of the belt transmission mechanism loses transmission. Multiple take-up wheels can be driven to rotate by a single power shaft. The operation is simple and easy to use. Through the setting of the take-up wheels on both sides and the contraction of the pull rope, the take-up wheels are driven to rotate and the sliding block is driven to move, which drives the air blowing head to move and adjust the position. The moisture on the corrugated pipe can be effectively blown to the bottom for cleaning. The dewatering effect is good, and the position of the air blowing head can be quickly adjusted according to the size of the pipe for adaptive adjustment, and accurate point-to-point water blowing is achieved.

[0018] Step 3: Cutting is performed through the cutting assembly. The push cylinder is started to drive the sliding sleeve to slide above the fixed machine. After the sliding sleeve moves to the left to the limit on the fixed machine, the gear set in the fixed frame drives the push rod to move to the left and extend to the limit. At this time, the expansion airbag is driven to move into the inside of the bellows. Then the air pump supplies air to the air cavity and supplies air to the expansion airbag through the telescopic pipe. The expansion airbag expands to support the inner wall of the bellows. Then the cutting assembly cuts the bellows, which can effectively prevent deformation during cutting and improve the molding quality. The push rod and the sliding sleeve have double-stroke movement and a longer stroke, which can be suitable for cutting longer pipes. After cutting, the push rod and the sliding sleeve are reset.

[0019] Step 4: Guide the bellows downward by setting a guide plate so that the bellows tilts downward and is output from the discharge chute.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention, through the arrangement of the take-up wheels on both sides and the contraction of the pull rope, drives the take-up wheels to rotate and drives the sliding block to move, driving the blowing head to move and adjust the position, which can effectively blow the moisture on the corrugated pipe to the bottom for cleaning, with good dewatering effect, and can quickly adjust the position of the blowing head according to the size of the pipe for adaptive adjustment, and accurately blow water point to point.

[0022] 2. The present invention can pull the bellows by adapting the surface of the bellows when the inner guide groove rotates, ensuring that the bellows can be transported smoothly.

[0023] 3. The present invention supplies air to the expansion bag through a telescopic pipe. The expansion bag expands to support the inner wall of the corrugated pipe. Then the cutting assembly cuts the corrugated pipe, which can effectively prevent deformation caused by cutting and improve the molding quality. In addition, the push rod and the sliding sleeve have a double-stroke movement with a longer stroke, which can be suitable for cutting longer pipes. BRIEF DESCRIPTION OF THE DRAWINGS

The blowing head 5 is connected to the external air source. The surface of the take-up wheel 8 is connected to the pull rope 6 fixed to one side of the sliding block 4. The surface of the power shaft 9 is connected to the take-up wheel 8 through a belt transmission mechanism 27. There are two take-up wheels 8 and power shafts 9, and they are symmetrically arranged on both sides of the ring 2. The inner cavity of the fixed machine 1 is fixedly connected to a driving cylinder 10. One end of the piston rod of the driving cylinder 10 is rotatably connected to a tensioning wheel 11 that abuts the belt on the surface of the belt transmission mechanism 27. The movement of the tensioner wheel 11 squeezes the belt transmission mechanism 27. After the belt is tightened, the rotation of the power shaft 9 can drive the take-up wheel 8 to rotate. When the driving cylinder 10 is retracted, the tensioner wheel 11 is retracted, and the belt of the belt transmission mechanism 27 loses transmission. Multiple take-up wheels 8 can be driven to rotate by a single power shaft 9. The operation is simple and easy to use. Through the setting of the take-up wheels 8 on both sides and the contraction of the pull rope 6, the take-up wheels 8 are driven to rotate and the sliding block 4 is driven to move, driving the blowing head 5 to move and adjust its position, which can effectively blow the moisture on the corrugated pipe 100 to the bottom for cleaning, and has a good dewatering effect.

One end of the push rod 23 is fixedly connected to the expansion airbag 20. The surface of the fixed frame 22 is fixedly connected to the air cavity 18. The air outlet of the air pump 16 is connected to the inner cavity of the air cavity 18 through a connecting pipe 17. One side of the air cavity 18 is connected to the inner cavity of the expansion airbag 20 through a telescopic pipe 19. The piston end of the pushing cylinder 24 is fixedly connected to one side of the sliding sleeve 25. When cutting is performed through the cutting assembly 14, the pushing cylinder 24 is started to drive The sliding sleeve 25 slides above the fixed machine 1. After the sliding sleeve 25 moves to the left to the limit on the fixed machine 1, the gear set in the fixed frame 22 drives the push rod 23 to move to the left and extend to the limit. At this time, the expansion airbag 20 is driven to move into the inside of the bellows 100, and then the air pump 16 supplies air to the air cavity 18, and supplies air to the expansion airbag 20 through the telescopic pipe 19. The expansion airbag 20 expands to support the inner wall of the bellows 100. Then the cutting assembly 14 cuts the bellows 100 at this time, which can effectively prevent deformation during cutting and improve the molding quality. The push rod 23 and the sliding sleeve 25 move in a double stroke with a longer stroke, which can be suitable for cutting longer pipes. After cutting, the push rod 23 and the sliding sleeve 25 are reset.

[0036] One side of the sliding sleeve 25 is fixedly connected to a bottom receiving plate 26, and the top of the bottom receiving plate 26 is rotatably provided with a guide wheel that abuts against the bottom of the corrugated tube 100. Through the setting of the guide wheel, the bottom receiving plate 26 supports the bottom of the corrugated tube 100, which can ensure the stability of the corrugated tube 100 itself during cutting.
