[0002] Pipe forming refers to the process of manufacturing pipes or pipe fittings into the required shape and size through a specific process method; the heated molten plastic material is extruded through the forming die by an extruder to form a continuous pipe. The cooling process after pipe forming is an important part of pipe production, especially in the thermoforming process. The formed pipe is usually at a higher temperature. In order to ensure the dimensional stability and performance of the pipe, it needs to be cooled to room temperature or working temperature.

[0003] Water cooling is a commonly used method for cooling pipes after molding. Water is used as the cooling medium, and the pipes are quickly sprayed and cooled through water-cooled molds or water-cooled channels. However, when the pipes pass through the cooling device, the spray head is fixed and located above the pipes, and can only spray the upper part of the pipes. The lower part of the pipes is difficult to contact the cooling water, resulting in uneven heating of the pipes, which not only affects the performance of the pipes, but also affects the cooling effect of the pipes. Summary of the invention

[0004] The utility model solves the problem that the lower part of the pipeline is difficult to be cooled by spraying cooling water in the cooling device, and provides a cooling device for pipeline production, which can make the peripheral wall of the pipeline fully contact the cooling water, improve the cooling efficiency of the pipeline, and ensure the uniform temperature of the peripheral wall of the pipeline.

[0007] Furthermore, the right end of the rotating rod is rotatably connected to the right side plate of the box body, and the left end passes through the left side plate of the box body. A motor is fixed on the outer left side surface of the box body, and the left end of the rotating rod is connected to the output end of the motor; the lower end of the right side plate of the box body is connected to a liquid outlet pipe.

[0008] Furthermore, the left and right side plates of the box body are provided with through holes higher than the rotating rod, the through holes on the left and right side plates of the box body are circular holes and are opposite to each other, the circle where the arc groove is located is coaxial with the through hole, and the diameter of the through hole is larger than the diameter of the circle where the arc groove is located.

[0009] Furthermore, the central angle corresponding to the arc groove is 180 degrees.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figure 1 to Figure 5 As shown, a cooling device for pipeline production comprises a box body 1, the upper end opening of the box body 1 is blocked by a top plate, and the top plate of the box body 1 is evenly distributed with spray heads 2; it also comprises a rotating rod 3 and a driving member; the rotating rod 3 is arranged in the lower part of the box body 1 and rotates along the length direction of the box body 1, and the rotating rod 3 is a round rod; driving members are arranged in the box body 1 on the upper side of the rotating rod 3 from left to right, and the driving member comprises a vertical plate 4, a rotating wheel 5 and a belt body 6; there are two vertical plates 4, and the vertical plates 4 are rectangular plates. The top surface of the vertical plates 4 is depressed downward with an arc groove 7, and the front and rear ends are respectively fixedly connected to the front and rear inner surfaces of the box body 1, and the two vertical plates 4 are rotated between them. There are multiple rotating wheels 5 that are rotatably connected, and the rotating wheels 5 are cylindrical. The multiple rotating wheels 5 are arranged in a ring array along the circumferential direction of the arc groove 7. The diameter of the circle where one end of the multiple rotating wheels 5 is located facing the central axis of the arc groove 7 is smaller than the diameter of the circle where the arc groove 7 is located. Between the two vertical plates 4 on the front and rear sides above the multiple rotating wheels 5, a rotating rod 2 8 and a rotating rod 3 9 are rotatably connected respectively. The rotating rod 2 8 and the rotating rod 3 9 are both round rods. One end of the belt body 6 bypasses the upper side of the rotating rod 2 8, bends downward, and is located on the lower side of the rotating rod 1 3. The other end of the belt body 6 bypasses the upper side of the rotating rod 3 9 to connect the belt body 6 and is located at one end of the lower side of the rotating rod 1 3. The belt body 6 between the rotating rod 2 8 and the rotating rod 3 9 is in contact with the multiple rotating wheels 5.

[0023] The right end of the rotating rod 3 is rotatably connected to the right side plate of the box body, and the left end passes through the left side plate of the box body 1. A motor 10 is fixed to the outer left side surface of the box body 1, and the left end of the rotating rod 3 is connected to the output end of the motor 10; the lower end of the right side plate of the box body 1 is connected to a liquid outlet pipe 15.

[0024] The left and right side panels of the box body 1 are both provided with through holes 11 higher than the rotating rod 1. The through holes 11 on the left and right side panels of the box body 1 are all circular holes and are opposite to each other. The circle where the arc groove 7 is located is coaxial with the through hole 11, and the diameter of the through hole 11 is larger than the diameter of the circle where the arc groove 7 is located.

[0025] The central angle of the arc groove 7 is 180 degrees.

[0026] The middle part of the left side of each rotating wheel 5 is rotationally connected to the vertical plate 4 on the left side of the driving member via a rotating shaft 12, and the middle part of the right side of each rotating wheel 5 is rotationally connected to the vertical plate 4 on the right side of the driving member via a rotating shaft 2 13.

[0027] The belt body 6 is made of polyester material. The belt body 6 made of polyester material has good strength and durability, and is relatively inelastic, which can ensure stable friction during the transmission process. The width of the belt body 6 matches the spacing between the two vertical plates 4 of the driving member, and the peripheral wall of the rotating rod 3 is provided with friction lines 14.

[0028] When in use, the pipe that needs to be cooled after forming is passed through any through hole 11 and placed on the upper side of the wheels 5 of multiple driving members, and the lower part of the pipe wall is in contact with the multiple wheels on each driving member; cooling water is sprayed into the box body 1 through multiple spray heads 2, and the motor 10 is started at the same time. The motor 10 drives the rotating rod 1 3 to rotate. When the rotating rod 1 3 rotates, the belt body 6 on the multiple driving members is driven to rotate. Since the belt body 6 between the rotating rod 2 8 and the rotating rod 3 9 is in contact with the multiple wheels 5 on the driving member, when the belt body 6 rotates, it can drive the multiple wheels 5 on the driving member to rotate synchronously in the same direction. The wheels 5 on the drive member can rotate synchronously in the same direction, thereby driving the pipeline to rotate. When the pipeline rotates, the peripheral wall of the pipeline can contact the cooling water sprayed from top to bottom in all directions, thereby allowing the pipeline to be cooled evenly, thereby preventing the lower part of the pipeline from being difficult to contact with the cooling water. When a pipeline smaller than the diameter of the circle where one end of the multiple wheels 5 on the same driving member is located toward the central axis of the arc groove 7 is placed on the upper side of the wheels 5 of the multiple driving members of the utility model, when the rotating rod 3 rotates, the pipeline can be driven to rotate by the driving member. Therefore, the utility model has a wide range of uses. The cooling water entering the box body 1 can be discharged from the box body 1 through the liquid outlet pipe 15.

[0029] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
