Description

Technical Field

[0001] The utility model belongs to the technical field of pipe production cooling, in particular to a cooling trough for pipe extrusion. Background Art

[0002] Many existing plastic pipes are extruded through extruders. Since the extruded plastic has a high temperature, it cannot be directly reprocessed. Therefore, a cooling tank is installed next to the extruder to cool the extruded plastic with water.

[0003] The length of the existing cooling trough is fixed. When the pipe extruded by the extruder is too long, the pipe is prone to collision after moving to the tail of the cooling trough. Therefore, the pipe needs to be manually pulled upward, which is inconvenient and labor-intensive. Utility Model Content

[0006] As a preferred embodiment of the above technical solution, the positioning assembly includes a fixing plate fixed on the side wall of the lifting plate, the fixing plate is threadedly connected to a threaded rod, and the two ends of the threaded rod are respectively fixedly connected to a knob and an anti-slip pad, and the anti-slip pad is in contact with the inner wall of the cooling trough body.

[0008] As a preferred embodiment of the above technical solution, one end of one of the traction shafts passes through the side wall of the cooling trough body, a motor is fixedly installed on the outer wall of the cooling trough body, and the output end of the motor is fixedly connected to the end of the traction shaft that passes through the side wall of the cooling trough body.

[0009] As a preferred embodiment of the above technical solution, the traction mechanism also includes multiple traction wheels 2, the inner ring of each traction wheel 2 is fixedly sleeved with a traction shaft 2, both ends of the traction shaft 2 are rotatably connected with a sliding sleeve, the inner ring of the sliding sleeve is movably sleeved with a guide rod, the guide rod is fixed in a groove on the inner wall of the cooling tank body, and an elastic member is fixedly connected between the sliding sleeve and the side wall of the groove.

[0010] The beneficial effects of the utility model are:

[0011] 1. The traction mechanism of the utility model is responsible for transporting the pipe produced by the extruder from the head to the tail of the cooling trough body. During the movement, the pipe is cooled by the cooling water inside the cooling trough body. At the same time, the pipe is lifted to the outside of the cooling trough body by a lifting plate arranged in multiple steps, which can prevent the pipe from colliding with the outside of the cooling trough body and save labor costs.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example 1

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, a cooling trough for pipe extrusion includes a cooling trough body 1, a traction mechanism and a lifting mechanism are installed inside the cooling trough body 1, and the lifting mechanism includes a plurality of lifting plates 9 rotatably installed in the cooling trough body 1, the inner wall of the lifting plate 9 is rotatably connected to a lifting wheel 10, and the side wall of the lifting plate 9 is installed with a positioning component for controlling the angle, and the plurality of lifting plates 9 are arranged in a stepped manner from low to high, for lifting the pipe to the outside of the cooling trough body 1.

[0021] It should be noted that the cooling trough body 1 is divided into three areas, namely the head, the middle and the tail, wherein the head is close to the extruder, and the interval between two adjacent lifting plates 9 is greater than the width of the lifting plate 9, so that after being completely laid down to the interior of the cooling trough body 1, they will not collide with another lifting plate 9, and the traction mechanism is located on the side of the lowest lifting plate 9.

[0022] Specifically, the traction mechanism is responsible for transporting the pipe produced by the extruder from the head to the tail of the cooling trough body 1. During the movement, the pipe is cooled by the cooling water inside the cooling trough body 1. At the same time, the pipe will be lifted to the outside of the cooling trough body 1 by a lifting plate 9 arranged in multiple steps, which can prevent the pipe from colliding with the outside of the cooling trough body 1 and save labor costs.

[0023] like Figure 1 and Figure 3 As shown, the positioning assembly includes a fixing plate 11 fixed on the side wall of the lifting plate 9, the fixing plate 11 is threadedly connected to a threaded rod 12, and the two ends of the threaded rod 12 are respectively fixedly connected to a knob 13 and an anti-slip pad 14, and the anti-slip pad 14 is in contact with the inner wall of the cooling trough body 1. The anti-slip pad 14 is made of but not limited to rubber material.

[0024] Specifically, through the threaded cooperation between the threaded rod 12 and the knob 13, when the knob 13 is turned to drive the threaded rod 12 to rotate, the threaded rod 12 will drive the anti-slip pad 14 to rotate and move. When the anti-slip pad 14 is away from the side wall of the cooling trough body 1, the lifting plate 9 will rotate with the connection point with the cooling trough body 1 as the axis. When the anti-slip pad 14 conflicts with the inner wall of the cooling trough body 1, the lifting plate 9 will be unable to rotate.

[0025] Example 2

[0026] like Figure 1 As shown, the cooling trough for pipe extrusion, compared with embodiment 1, the traction mechanism of this embodiment includes multiple traction wheels 3, the inner ring of each traction wheel 3 is fixedly sleeved with a traction shaft 2, and the two ends of the traction shaft 2 are respectively rotatably connected to the two sides of the cooling trough body 1.

[0027] Specifically, when the pipe comes to the top of the traction wheel 3, the traction shaft 2 drives the traction wheel 3 to rotate and pull the pipe to move, avoiding the situation where the extruder cannot push the pipe to move because the pipe is too long.

[0028] like Figure 1 As shown, one end of one or more traction shafts 2 passes through the side wall of the cooling trough body 1, a motor is fixedly installed on the outer wall of the cooling trough body 1, and the output end of the motor is fixedly connected to the end of the traction shaft 2 passing through the side wall of the cooling trough body 1.

[0029] Specifically, the motor drives the traction shaft 1 2 connected thereto to drive the traction wheel 1 3 to rotate, and the pipe is pulled by the traction wheel 1 3.

[0030] like Figure 1 and Figure 2 As shown, the traction mechanism also includes a plurality of traction wheels 2 5, the inner ring of each traction wheel 2 5 is fixedly sleeved with a traction shaft 2 4, both ends of the traction shaft 2 4 are rotatably connected with a sliding sleeve 6, the inner ring of the sliding sleeve 6 is movably sleeved with a guide rod 7, the guide rod 7 is fixed in the groove of the inner wall of the cooling tank body 1, and an elastic member 8 is fixedly connected between the sliding sleeve 6 and the side wall of the groove, and the elastic member 8 uses but is not limited to a spring.

[0031] Specifically, when the pipe comes between the traction wheel 1 3 and the traction wheel 2 5, the pipe will push the traction wheel 2 5, the traction shaft 2 4 and the sliding sleeve 6 upward. At the same time, the force of the elastic member 8 will push the traction wheel 2 5 and the pipe to fit tightly together, which is used to increase the friction between the pipe and the traction wheel 1 3 and the traction wheel 2 5, so that the traction wheel 1 3 will not slip during the traction process.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
