Description

Technical Field

[0001] The utility model belongs to the technical field of PVC water pipe processing, and particularly relates to a PVC water pipe picking device at the extrusion end of a screw extruder. Background Art

[0002] PVC water pipes are a common type of plastic pipes, mainly used for drainage, irrigation, and some water supply systems. The full name of PVC pipes is polyvinyl chloride pipes, which are formed by hot pressing after mixing polyvinyl chloride resin with stabilizers, lubricants, etc. PVC-0 pipes are the most common type among them, mainly used for cold water supply systems and drainage pipes, while PVC-0 pipes are manufactured through a special orientation processing technology and have higher strength and toughness.

[0003] In the utility model with the publication number CN212194123U, a vacuum sizing device for water supply pipes is disclosed, which relates to the technical field of water pipe production equipment. The utility model includes a box body and a water discharge plate. A bearing plate is arranged on the outer wall of the bottom of the box body, and an equipment rack is welded on the outer wall of the support column above the bottom plate. The outer wall above the box body is fixedly connected with a water tank through a column. A first sizing groove is arranged inside the box body, a second sizing groove is arranged on the right side of the first sizing groove, and a fourth sizing groove is arranged on the right side of the third sizing groove. Through a series of structures, the utility model solves the problems of the existing PE water pipe vacuum sizing equipment: when water-cooling and shaping the water pipe, directly spraying water on the outer wall of the water pipe causes the temperature of the water pipe to drop suddenly, resulting in a decrease in the strength of the water pipe, making it more brittle and prone to fracture; at the same time, there are still a large number of water stains remaining on the outer wall of the pipe after sizing; and a small part of the cooling water in the sizing equipment remains inside the equipment and is difficult to remove. However, the above device cannot support water pipes of different sizes during cooling, which may cause deformation of the water pipes during cooling, and the water pipes cannot be transported after cooling, which may cause the uncooled water pipes to be unable to push the cooled and sized water pipes, resulting in deformation of the uncooled water pipes. Therefore, it is necessary to provide a PVC water pipe picking device at the extrusion end of a screw extruder to solve the above problems. Content of the Utility Model

A PVC water pipe picking device at the extrusion end of a screw extruder includes: a conveying cylinder 2 provided at the upper ends of two groups of positioning seats 1, multiple groups of nozzles 3 are provided inside the conveying cylinder 2, a supporting component is provided at the middle position of the lower surface of the conveying cylinder 2, an adjusting component is provided at the upper end of the front positioning seat 1, and two groups of conveying components are oppositely arranged inside the adjusting component; the supporting component includes an adjusting rod 4, and the adjusting rod 4 is provided at the middle position of the lower surface of the conveying cylinder 2; the adjusting component includes an adjusting frame 8, and the adjusting frame 8 is fixedly installed at the upper end of the front positioning seat 1; the two groups of conveying components include a mounting plate 16, and the mounting plate 16 is provided inside the adjusting component.

[0025] The supporting component further includes a turning handle 5, the turning handle 5 is fixedly installed at the lower end of the adjusting rod 4, and the upper end of the adjusting rod 4 is connected with a supporting ring 6. The outer surface of the adjusting rod 4 is provided with a threaded structure, and a threaded hole matching it is opened at the lower end of the conveying cylinder 2. The supporting ring 6 is rotatably installed at the upper end of the adjusting rod 4, and first limiting rods 7 are provided on both sides of the lower surface of the supporting ring 6, and the two groups of first limiting rods 7 are movably inserted into the lower surface of the conveying cylinder 2. By rotating the turning handle 5, the adjusting rod 4 is driven to move in the threaded hole opened at the lower end of the conveying cylinder 2 through the threaded structure. Since the upper end of the adjusting rod 4 is rotatably connected with the supporting ring 6, and the first limiting rods 7 are movably inserted into the conveying cylinder 2 on the lower side of the supporting ring 6, the supporting ring 6 moves in the conveying cylinder 2, which is convenient for adjusting according to water pipes of different diameters, thereby facilitating the support of the water pipe and preventing the water pipe from deforming.

[0026] The adjusting assembly further includes a connecting rod 9. The connecting rod 9 is arranged at the upper end inside the adjusting frame 8. The left end of the connecting rod 9 is connected with a driving motor 10, and the driving motor 10 is fixedly installed on the left side of the adjusting frame 8. First belt pulleys 11 are arranged at both ends of the connecting rod 9 and on the left and right sides of the lower end inside the adjusting frame 8. And the four groups of first belt pulleys 11 are respectively connected by two groups of first crawlers 12. Push rods 13 are inserted inside the lower two groups of first belt pulleys 11. And the ends of the two push rods 13 close to each other are both connected with a positioning frame 14. The outer surfaces of the two push rods 13 are provided with relative thread structures, and threaded holes matching them are opened inside the lower two groups of first belt pulleys 11. Second limiting rods 15 are arranged on the sides of the two positioning frames 14 away from each other, and the two second limiting rods 15 are respectively movably inserted on the left and right sides of the conveying cylinder 2. By turning on the driving motor 10, the connecting rod 9 is driven to rotate, thereby driving the first belt pulleys 11 and the first crawlers 12 to rotate. Through the push rods 13 inserted into the lower two groups of first belt pulleys 11 by threads and the second limiting rods 15 arranged on one side of the positioning frame 14 inserted on the conveying cylinder 2, when the lower two groups of first belt pulleys 11 rotate, the push rods 13 are driven to move relatively, thereby pushing the conveying assembly to clamp the water pipe, facilitating the conveyance of the water pipe.

[0027] The two groups of conveying assemblies further include second belt pulleys 17, and the two groups of second belt pulleys 17 are connected by a second crawler 18. And a conveying motor 19 is arranged on the upper side of the upper mounting plate 16.

[0028] Arc-shaped structures are arranged on the outer sides of the two groups of second belt pulleys 17, and the two groups of second crawlers 18 are arranged in a structure matching them. The matching design of the arc-shaped structure and the second crawler 18 can ensure that the power transmission during the transmission process is more stable and efficient. This structure can reduce the sliding between the water pipe, the second belt pulleys 17 and the second crawler 18, thereby improving the transmission efficiency and reducing energy loss. The arc-shaped structure helps to keep the second crawler 18 in the correct position on the second belt pulley 17, preventing the second crawler 18 from falling off or shifting, thereby increasing the stability and reliability of the transmission system.

[0029] Working principle: During use, by adjusting the supporting assembly to a position suitable for the water pipe, and then through the adjusting assembly, the two groups of conveying assemblies are adjusted to a position suitable for the water pipe. After the water pipe enters from the rear end of the conveying pipe, the water pipe is supported by the supporting assembly, and then the conveying pipe is cooled by spraying water through the nozzle 3, and then the cooled water pipe is pulled out by the conveying assembly.
