Description

Technical Field

[0001] The utility model relates to the technical field of hose processing equipment, in particular to a device for cooling a hose during the hose processing process. Background Art

[0002] When producing a hose, raw materials such as polyethylene, polypropylene, polyvinyl chloride, etc. and additives need to be put into a kneader together. Through the heating and mechanical action of the kneader, each component is fully mixed to form a plasticizable material. Then, the kneaded material is put into an extruder, and the material is extruded from a die under high pressure to form a preliminary shape of the hose. Due to the high temperature of the extrusion die, the temperature of the extruded hose is relatively high, and it is necessary to use a cooling device for cooling and solidification, which helps to stabilize its shape and improve its strength, so as to realize continuous extrusion production by pulling the hose.

[0003] At present, the cooling device used in hose production generally includes a cooling rack and a cooling water tank supported by the cooling rack at a high position. Under the action of a pulling device, the hose passes through the cooling water tank. During the process, the hose is quickly cooled and shaped by continuously supplied cold water. However, in the actual use process, since the diameters of the hoses to be processed and produced are different, it is necessary to replace the die head of the extrusion die. However, the die head is relatively close to the cooling water tank, and the disassembly and assembly operations are inconvenient and inefficient. If the above problems are solved by moving the cooling water tank, the cooling water tank is heavy, and it is time-consuming and laborious to move, so the above problems cannot be fundamentally solved. In addition, the height of the currently used cooling water tank is relatively fixed. When the diameters of the processed hoses are different, it is difficult to take into account both the cooling effect and the smooth pulling and advancing of the hose. Based on the above two technical problems, it is necessary to further improve the cooling device in hose production. Summary of the Utility Model

Detailed implementation manners

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and description are illustrative in nature and not used to limit the protection scope of the claims.

[0020] As Figure 1 and Figure 2 shown, the hose processing cooling device is used to receive the cooling water for cooling the hose after the hose is extruded and formed by the extrusion die head 14, and at the same time, the auxiliary support and transportation of the towed hose can be carried out by means of the installed rollers. Specifically, it includes a support bottom frame 1, a support top frame 2 is provided directly above the support bottom frame 1, a cooling water tank 3 is provided directly above the support top frame 2, and the support bottom frame 1 and the support top frame 2 cooperate to support the cooling water tank 3 at a raised height so that its height can match the position of the extrusion die head 14. Both the support bottom frame 1 and the support top frame 2 can be welded by steel pipes made of stainless steel. The cooling water tank 3 is a long trough with an open top, and avoidance openings for facilitating the progress of the hose are provided at both ends. A number of rollers can also be installed in a linear arrangement inside it to facilitate the auxiliary transportation of hoses with large diameters. The cooling water tank 3 is well-known to those of ordinary skill in the art and will not be described in detail here.

[0021] In this embodiment, a top frame lifting and adjusting device is arranged and connected between the support bottom frame 1 and the support top frame 2, and a water tank translation device is arranged across the top of the support top frame 2, and the bottom end of the cooling water tank 3 abuts against each of the water tank translation devices. By operating the top frame lifting and adjusting device, the height of the support top frame 2 can be adjusted, thereby indirectly adjusting the height of the cooling water tank 3 so that it can better cooperate with the extrusion die head 14, facilitating the processing of hoses with different diameters, enabling the hose to smoothly travel along the cooling water tank 3, and eliminating the problem of spatial interference between its travel and the cooling water tank 3 when processing large-diameter hoses. By operating the water tank translation device, the cooling water tank 3 can be conveniently translated to change the distance between it and the extrusion die head 14, thereby facilitating the provision of a larger replacement operation space for replacing the extrusion die head 14 when producing hoses with different diameters.

[0022] Among them, the water tank translation device includes at least two water tank moving rollers 4 arranged and installed on the support top frame 2. The cooling water tank 3 is arranged at the top of each of the water tank moving rollers 4, and a roller body rotation handle 5 is fixedly installed at the end of at least one of the water tank moving rollers 4. The roller body rotation handle 5 can be set as a handwheel. When it is necessary to move the cooling water tank 3, the water tank connected to it is rotated through the roller body rotation handle 5. Under the action of the friction force between the two, the cooling water tank 3 generates translation. To ensure the smoothness of the translation of the cooling water tank 3, a rubber layer or other structures that can increase the friction force between the two can be coated on the outer circumference of the water tank moving roller 4. In addition, to improve the labor-saving property of the translation of the cooling water tank 3, the roller body rotation handle 5 can be correspondingly installed on multiple water tank moving rollers 4, and multiple people can operate to make its moving efficiency higher.

[0023] In this embodiment, a roller body blocking pin 6 is movably inserted at the bottom end of the water tank moving roller 4 correspondingly connected to the roller body rotation handle 5. The roller body blocking pin 6 penetrates through the support top frame 2, and the roller body blocking pin 6 is in threaded cooperation with the water tank moving roller 4 and / or the support top frame 2. When the cooling water tank 3 moves to the target position, the end of the roller body blocking pin 6 can be inserted into the water tank moving roller 4 to block the rotation of the water tank moving roller 4 by using the roller body blocking pin 6. The main purposes are as follows:

[0024] First, to improve the fixing property of the cooling water tank 3. When producing large-diameter hoses, during the pulling process of the hose, it is necessary to prevent indirectly generating a traction force on the cooling water tank 3, so as to prevent the cooling water tank 3 from generating unnecessary displacement.

[0025] Second, improve the safety of operation. When adjusting the support top frame 2 by using the top frame lifting and adjusting device, generally one end is adjusted first and then the other end. When there is a height difference between the two ends of the support top frame 2, its top support is in an inclined state, and the cooling water tank 3 may have a sliding phenomenon due to uneven gravity. The rolling of the water tank moving roller 4 can increase the sliding effect of the cooling water tank 3. After setting the roller stall pin 6, the above phenomenon can be avoided.

[0026] On both sides of the cooling water tank 3 on the support top frame 2, there are also water tank limiting devices respectively, which are used to keep the cooling water tank 3 coaxial with the extrusion die head 14. Specifically, the water tank limiting device includes a limiting vertical frame 7 fixedly installed on the support top frame 2, a limiting screw rod 8 threadedly assembled through the limiting vertical frame 7, the inner end of the limiting screw rod 8 is connected with a limiting top block 9, and the limiting top block 9 abuts against the side wall of the cooling water tank 3, playing a role in assisting in fixing the cooling water tank 3. The limiting top block 9 can be set as a rubber block, forming a flexible contact with the outer wall of the cooling water tank 3, which helps to prevent wear on its outer wall. A rotating handle can be installed at the outer end of the limiting screw rod 8 to facilitate its rotation and improve the operation efficiency.

[0027] The top frame lifting and adjusting device includes a top frame lifting screw rod 10. The top end of the top frame lifting screw rod 10 is fixedly installed on the support top frame 2, the bottom end of the top frame lifting screw rod 10 is movably inserted into the support bottom frame 1, and a lifting operation nut 11 is threadedly sleeved on the top frame lifting screw rod 10, and the lifting operation nut 11 is rotatably installed at the top end of the support bottom frame 1. By rotating the lifting operation nut 11, the length of the top frame lifting screw rod 10 inserted into the support bottom frame 1 can be changed, thereby changing the distance between the support bottom frame 1 and the support top frame 2, achieving the purpose of adjusting the height of the support top frame 2. For convenient operation, an easy-to-use operation handle 12 or operation handwheel can be installed on the lifting operation nut 11. As Figure 2 and Figure 3 shown, the installation position of the top frame lifting screw rod 10 can be adjusted according to specific circumstances. When the top frame lifting screw rod 10 is set at the position as Figure 2 shown, a lifting locking top pin 13 can be correspondingly provided below the lifting operation nut 11 on the support bottom frame 1, and the inner end of the lifting locking top pin 13 abuts against the surface of the top frame lifting screw rod 10. The position of the top frame lifting screw rod 10 is assisted in being locked by the lifting locking top pin 13 to improve the firmness of the support for the support top frame 2.
