Description

Technical Field

[0001] This utility model relates to the field of air conditioning hose production technology, and in particular to an automatic traction device for air conditioning hose production. Background Technology

[0002] Air conditioning hoses are pipes specifically designed for transporting refrigerant liquids and are widely used in industrial and civil applications. Air conditioning hoses are typically made of multiple layers of materials and can withstand the tension, expansion, and displacement of the pipes within the pipeline, as well as a certain amount of pressure. During the production of air conditioning hoses, an automatic traction device is required for guidance.

[0003] Existing technology, such as publication number CN214114466U, discloses a hose traction device. This device uses a handwheel to rotate, which, via a screw, allows the upper synchronous belt to move up and down, increasing or decreasing the distance between the upper and lower synchronous belts to meet the production needs of hoses with different diameters… thereby generating a stable traction force, ensuring the hose diameter is within its permissible range, and adapting to a certain range of hose sizes. However, the technical solution of the aforementioned patent has the following shortcomings: 1. Its guide roller is screwed and fixed inside the guide hole, requiring the guide roller to be removed to adjust the spacing, which is very inconvenient; 2. A limiting structure is required when the hose is pulled out, which can easily lead to hose displacement during output. Utility Model Content

[0011] Preferably, a rotating bearing is fixedly connected to the lower end of the U-shaped seat below, and the adjusting screw is fixedly connected to the rotating bearing.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By screwing the threaded joint on the vertical limit roller into the threaded hole on the circular connecting block, the servo motor, together with the two movable blocks, adjusts the limiting distance between the two vertical limit rollers under the limiting action of the slide groove and the limiting protrusion. The structure is simple and easy to operate.

[0014] 2. By turning the adjusting screw, the U-shaped frame and rotating bearing are used to drive the horizontal limiting roller inside the lower U-shaped seat to rise vertically.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5An automatic traction device for air conditioner hose production includes an automatic traction device body 1. The automatic traction device body 1 has two fixed frames 2 inside. A fixed seat 3 is fixedly connected to the right front side wall of the lower fixed frame 2. A servo motor 4 is fixedly installed on the front side wall of the fixed seat 3. A rectangular groove 5 is provided at the upper end of the fixed seat 3. Two vertical limiting rollers 6 are provided in the rectangular groove 5. A bidirectional lead screw 9 is horizontally rotatably inserted through the inner walls of the front and rear sides of the rectangular groove 5. One end of the bidirectional lead screw 9 outside the rectangular groove 5 is fixedly connected to the drive shaft of the servo motor 4. Movable blocks 10 are threadedly sleeved on both sides of the threaded section of the bidirectional lead screw 9. Circular connecting blocks 11 are fixedly connected to the upper ends of the two movable blocks 10. Threaded holes 12 are provided at the upper ends of the two circular connecting blocks 11. Threaded joints 13 are rotatably connected to the lower ends of the two vertical limiting rollers 6. The two threaded joints 13 are respectively... The two vertical limiting rollers 6 are threadedly connected to the two threaded holes 12, and the two vertical limiting rollers 6 are respectively connected to the two movable blocks 10. The threaded joints 13 at the lower end of the two vertical limiting rollers 6 are threadedly connected to the threaded holes 12 at the upper end of the two movable blocks 10. The bottom of the rectangular groove 5 is provided with a sliding groove 14. The lower end of each of the two movable blocks 10 is provided with a limiting protrusion 15. The two limiting protrusions 15 are inserted into the sliding groove 14 and slide against each other. The limiting protrusions 15 and the movable blocks 10 are integrally formed. The servo motor 4 drives the bidirectional lead screw 9 to rotate, so that the rotation of the bidirectional lead screw 9 drives the two threaded movable blocks 10 to move horizontally relative to each other under the limiting action of the sliding groove 14 and the limiting protrusions 15, until the hose slides against the annular sidewall of the two vertical limiting rollers 6. This makes it easy to adjust the limiting distance of the two vertical limiting rollers 6 according to actual needs. The structure is simple and easy to operate.

[0024] Mounting seats 7 are fixedly connected to the left sidewalls of the two fixed frames 2 near the opposite sidewalls. Horizontal limiting rollers 8 are provided on the opposite sidewalls of the two mounting seats 7 away from the fixed frames 2. U-shaped seats 16 are provided on the opposite sidewalls of the two mounting seats 7 away from the fixed frames 2. The upper U-shaped seat 16 is fixedly welded to the lower end of the upper mounting seat 7. The openings of the two U-shaped seats 16 are arranged opposite each other. The two horizontal limiting rollers 8 are rotatably connected to the openings of the two U-shaped seats 16 respectively. Annular limiting grooves 17 are provided on the annular sidewalls at the center of the two horizontal limiting rollers 8. The rubber tube pulled out by the automatic traction device body 1 is set through the two horizontal limiting rollers 8, so that the two horizontal limiting rollers 8 cooperate with the annular limiting grooves 17 to provide a limit on the rubber tube, preventing the rubber tube from being pulled and displaced. The adjusting mechanism is fixedly connected to the lower end of the lower U-shaped seat 16.

[0025] An adjustment mechanism is provided at the upper end of the lower mounting base 7 away from the fixed frame 2.

An adjusting screw 20 is fixedly connected to the rotating bearing 22. Turning the adjusting screw 20, together with the U-shaped frame 19 and the rotating bearing 22, drives the horizontal limiting roller 8 in the lower U-shaped seat 16 to rise vertically. Adjusting the limiting distance between the two horizontal limiting rollers 8 allows the rubber tube pulled out by the automatic traction device body 1 to pass through the two horizontal limiting rollers 8, so that the two horizontal limiting rollers 8, together with the annular limiting groove 17, provide a limiting distance for the rubber tube and prevent the rubber tube from shifting.

[0026] In use, the two vertical limiting rollers 6 are respectively connected to the two movable blocks 10, so that the threaded joints 13 at the lower end of the two vertical limiting rollers 6 are threadedly connected to the threaded holes 12 at the upper end of the two movable blocks 10. The hose to be pulled is passed through the two vertical limiting rollers 6. The servo motor 4 is started to drive the bidirectional lead screw 9 to rotate. The rotation of the bidirectional lead screw 9 causes the two threaded movable blocks 10 to move horizontally relative to each other under the limiting action of the slide groove 14 and the limiting protrusion 15, until the hose is aligned with the two vertical limiting rollers 6. The annular sidewalls slide against each other, making it easy to adjust the limiting distance between the two vertical limiting rollers 6 according to actual needs. The structure is simple and easy to operate. Turning the adjusting screw 20, together with the U-shaped frame 19 and the rotating bearing 22, drives the horizontal limiting roller 8 in the lower U-shaped seat 16 to rise vertically. Adjusting the limiting distance between the two horizontal limiting rollers 8 allows the rubber tube pulled out by the automatic traction device body 1 to pass through the two horizontal limiting rollers 8, so that the two horizontal limiting rollers 8, together with the annular limiting groove 17, provide a limiting distance for the rubber tube and prevent the rubber tube from shifting.
