Description

Technical Field

[0001] This utility model relates to the field of pipeline production technology, specifically to a cooling device for PE pipe production. Background Technology

[0002] PE pipe (polyethylene pipe) is a thermoplastic pipe made of polyethylene resin as the main raw material through extrusion molding process. It has excellent physical, chemical and mechanical properties and is widely used in water supply and drainage, gas, agriculture, industry and other fields.

[0003] Cooling PE pipes is a crucial step in the PE pipe production process, directly affecting the quality and performance of the pipes. One method for cooling PE pipes is to spray cooling water using a spray device to cool the formed PE pipes. However, when the cooling water is sprayed from top to bottom onto the PE pipe, only the top of the PE pipe receives the spray, resulting in a small contact area between the PE pipe and the cooling water, which affects the cooling effect of the PE pipe. Summary of the Invention

[0004] This invention addresses the problem of small contact area between PE pipes and cooling water when using a spray system to cool PE pipes. It provides a cooling device for PE pipe production that improves the cooling efficiency and effect of PE pipes.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A cooling device for PE pipe production includes a housing with multiple spray heads on the top plate, a feed hole, and a support component. Feed holes are located on the upper part of both the front and rear side plates of the housing. The support component includes a U-shaped frame, a through hole, and a support rod assembly. The U-shaped frame is slidably disposed within the housing below the feed hole. A through hole, lower than the feed hole, is located on the front side plate of the housing, with multiple teeth on its bottom surface. Support rod assemblies are spaced apart within the U-shaped frame. Each support rod assembly includes a first rod and a second rod. The rear end of the first rod is rotatably connected to the rear side plate of the U-shaped frame, and the front end of the first rod extends through the front side plate of the U-shaped frame into the through hole, where it is connected to a gear that meshes with the teeth within the through hole. The second rod is located to the right of the first rod, and its two ends are rotatably connected to the front and rear side plates of the U-shaped frame, respectively.

[0007] Furthermore, the lower part of the box is connected to a water outlet pipe; the front and rear outer sides of the U-shaped frame slide in contact with the front and rear side plates of the box, respectively, and the length of the U-shaped frame is less than the length of the box.

[0008] Furthermore, the front and rear side panels of the box are respectively provided with sliding holes corresponding to the front and rear side panels of the U-shaped frame, and sliding plates are connected to the front and rear outer surfaces of the U-shaped frame, with each sliding plate extending into the sliding hole on the same side.

[0009] Furthermore, the housing is provided with a driving component for driving the loop frame to slide left and right. The driving component includes a threaded cylinder and a threaded rod. The threaded cylinder is connected to the outer right side of the loop frame. A motor is fixed to the outer right side of the housing. The output end of the motor is connected to a threaded rod with its free end moving through the right side plate of the housing. The threaded rod extends into the threaded cylinder and is threadedly connected to the threaded cylinder.

[0010] Furthermore, when the spiral frame moves from the right side plate of the screw cylinder to the left and the left end of the spiral frame contacts the left side plate of the box, the gear on each rod is driven to rotate by teeth at an angle greater than 360 degrees.

[0011] Furthermore, each of the feed holes is provided with a door that can be opened or closed.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] In this invention, each support rod group within the loop-shaped frame carries a PE pipe. When the spray head sprays water onto the PE pipe for cooling, the loop-shaped frame moves to the left or right. As each support rod group moves with the loop-shaped frame, the rod on the support rod group can drive the PE pipe on that support rod group to rotate around its own central axis, so that the peripheral wall of the PE pipe is fully in contact with the cooling water, thereby improving the cooling effect and efficiency of the PE pipe.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-4 As shown, a cooling device for PE pipe production includes a box body 1, which is a rectangular box with its lower opening sealed by a bottom plate. The top plate of the box body 1 is provided with multiple spray heads 2. It also includes a feed inlet 3 and a support component. The upper part of both the front and rear side plates of the box body 1 is provided with feed holes 3, which are rectangular holes opened along the length of the box body 1. The support component includes a U-shaped frame 4, a through hole 5, and a support rod assembly. The U-shaped frame 4 is a rectangular frame with openings at both the upper and lower ends. The U-shaped frame 4 slides left and right within the box body 1 below the feed holes 3. The front side plate of the box body 1 is provided with a lower section than the feed holes 3. The through hole 5 is an elongated hole opened along the length of the box body 1. The bottom surface of the through hole 5 is provided with multiple teeth 6. The bearing rod group is provided from left to right in the ring frame 4. The bearing rod group includes rod body 7 and rod body 8. Both rod body 7 and rod body 8 are round rods with the same diameter. The rear end of rod body 7 is rotatably connected to the rear side plate of the ring frame 4. The front end of rod body 7 movably passes through the front side plate of the ring frame 4 and extends into the through hole 5, and is connected to a gear 9 that meshes with the teeth 6 in the through hole 5. Rod body 8 is located to the right of rod body 7. The two ends of rod body 8 are rotatably connected to the front and rear side plates of the ring frame 4, respectively.

[0021] The lower part of the box 1 is connected to a water outlet pipe 10, which is lower than the U-shaped frame; the front and rear outer sides of the U-shaped frame 4 respectively slide in contact with the front and rear side plates of the box 1, and the length of the U-shaped frame 4 is less than the length of the box 1.

[0022] The front and rear side panels of the box body 1 are respectively provided with sliding holes 11 corresponding to the front and rear side panels of the U-shaped frame 4. The sliding holes 11 are elongated holes opened along the length direction of the box body 1. Slide plates 12 are connected to the front and rear outer surfaces of the U-shaped frame 4. Each slide plate 12 extends into the sliding hole 11 on the same side. The slide plate 12 is a rectangular plate that slides in contact with the sliding hole 11 on the same side.

[0023] The housing 1 is equipped with a driving component for driving the loop frame 4 to slide left and right. The driving component includes a threaded cylinder 13 and a threaded rod 14. The threaded cylinder 13 is connected to the outer right side of the loop frame 4. A motor 15 is fixed to the outer right side of the housing 1. The output end of the motor 15 is connected to a threaded rod 14, the free end of which moves through the right side plate of the housing 1. The threaded rod 14 extends into the threaded cylinder 13 and is threadedly connected to the threaded cylinder 13. In the initial state, the threaded cylinder 13 on the loop frame 4 contacts the right side plate of the housing 1. The threaded rod 14 rotates clockwise to drive the loop frame 4 to move to the left until the left end of the loop frame 4 contacts the left side plate of the housing 1. The loop frame 4 moves to the left to its limit, and the motor 15 starts to drive the threaded rod 14 to rotate counterclockwise, and the loop frame 4 moves to the right to the initial state. The motor model selected in this utility model is Y2-100L1-4.

[0024] When the spiral frame 4 moves from the right side plate of the housing 1 to the left from the contact of the threaded cylinder 13 to the left side plate of the housing 1, the gear 9 on each rod is driven by the teeth 6 to rotate at an angle greater than 360 degrees.

[0025] Each of the feed holes 3 is provided with a door 16 that can be opened or closed. When the door is closed, it can prevent the cooling water sprayed by the spray head 2 from splashing out of the box 1.

[0026] In use, open the gate 16 on the feed hole 3. A PE pipe 17 requiring cooling is placed on each support rod group. The PE pipe 17 is supported by rod 7 and rod 8 on its respective support rod group. Close the gate 16 on the feed hole 3. Multiple spray heads spray cooling water onto the PE pipe 17 inside the U-shaped frame 4. The motor 15 drives the threaded rod 14 to rotate clockwise. Because the sliding plates at the front and rear ends of the U-shaped frame 4 are limited within the sliding holes 11, the U-shaped frame 4 can only move left and right. The clockwise rotation of the threaded rod 14 drives the U-shaped frame 4 to move to the left. When the U-shaped frame 4 moves to the left, multiple rods 7 and the PE pipe 17 move to the left along with the U-shaped frame 4. The gear 9 connected to the front end of rod 7 is engaged by teeth 6 and rotates counterclockwise. When the frame moves to the left, rod 7 drives the PE pipe 17 on its supporting rod group to rotate clockwise, and the PE pipe 17 drives rod 8 on its supporting rod group to rotate counterclockwise. Therefore, when the frame moves to the left, it can drive multiple PE pipes 17 to rotate around their own central axis, so that when each PE pipe 17 rotates, its peripheral wall comes into full contact with the cooling water. Similarly, when the frame moves to the right, each rod 7 rotates clockwise, and the PE pipe 17 on each supporting rod group of rod 7 rotates counterclockwise, which can also make each PE pipe 17 rotate, increasing the contact area between the PE pipe 17 and the cooling water, and improving the cooling effect and cooling efficiency.

[0027] After the PE pipe 17 is cooled, the cooling water enters the lower part of the box 1 and is discharged through the outlet pipe 10. After the PE pipe 17 is cooled, the motor and multiple spray heads 2 stop working. Open the door 16 and take out the PE pipe 17.

[0028] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
