Description

Technical Field

[0001] The utility model belongs to the technical field of strip printers, and particularly relates to a traction device for cables. Background Art

[0002] A strip printer is a machine that prints strip patterns onto cable materials through ink transmission and transfer. The strip printer uses the traction of a motor to transfer the cable from one coil to another. During the transfer process, the cable undergoes operations such as inking, baking, and winding. From the perspective of the prior art, common strip printers require manual traction during use, which is labor-intensive, time-consuming, and the current strip printers are large in size, and workers need to climb up and down to handle them, which is prone to hazards. Therefore, we have designed a traction device for cables.

[0003] It should be noted that the above content belongs to the technical cognitive scope of the utility model people and does not necessarily constitute the prior art. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a traction device for cables, which has the advantages of automatically traction the cable without affecting subsequent operations.

[0005] To achieve the above purpose, the utility model proposes a traction device for cables, including a driving motor and a chain for power transmission. The outer shell of the driving motor is fixedly connected to a supporting mounting rack, and a gear is installed at the output end of the driving motor. A chain is sleeved on the side of the gear. One end of the chain is sleeved on the gear, and the other end of the chain is provided with three driven wheels. Tooth openings are formed on the sides of the three driven wheels. The three driven wheels and the gear are all installed inside the chain. A tension wheel is installed on the outside of the chain. A tooth opening is formed on the side of the tension wheel. A connecting frame is installed on the side of the chain. A support rod is installed on the side of the connecting frame away from the chain. A pendant is installed on the support rod.

[0006] Preferably, the pendant is in a conical structure, and a hanging groove is formed on the pendant. The hanging groove penetrates through one side of the pendant. The pendant is hung on the support rod through the hanging groove. A support frame is installed on the side of the pendant away from the cone. The support frame is fixedly connected to the pendant and integrally formed. A perforation is formed on the support frame.

[0007] Preferably, the tooth openings on the sides of the driven wheels and the tension wheel are all connected to the chain, and the plane sides of the driven wheels and the tension wheel are rotatably connected to the supporting mounting rack through a rotating shaft.

[0008] Preferably, a winding shaft is installed between the driven wheel and the tension wheel. One end of the winding shaft is fixedly connected to the mounting bracket, and the other end of the winding shaft is rotatably connected to a winding wheel. A notch for cable conduction is provided on the arc-shaped side of the winding wheel, and the winding wheel is placed inside the chain.

[0009] Preferably, a cable is inserted through the perforation on the support frame, and the running direction of the cable is the same as that of the chain.

[0010] The cable traction device proposed by the present utility model can bring the following beneficial effects:

[0011] 1. In the present utility model, the driving motor is used to drive the chain to rotate, and the installation of the tension wheel facilitates the adjustment of the chain tension. The pendant is hung by the support rod installed on the side of the chain, and the cable passes through the pendant. The pendant then drives the pendant to rotate in the same direction through the chain. When the perforation on the pendant drives the cable to the vertical position beside the winding wheel, it is convenient to traction the cable onto the winding wheel. When the cable runs to subsequent work, since the cable drives the pendant to tilt, the pendant disengages from the support rod and the pendant falls to the bottom of the chain.

The outer shell of the driving motor 1 is fixedly connected to a supporting mounting frame 5, and a gear 2 is installed at the output end of the driving motor 1. A chain 3 is sleeved on the side of the gear 2. One end of the chain 3 is sleeved on the gear 2, and the other end of the chain 3 is provided with three groups of driven wheels 4. Tooth openings are formed on the sides of the three groups of driven wheels 4. The three groups of driven wheels 4 and the gear 2 are all installed inside the chain 3. A tension wheel 6 is installed outside the chain 3. A tooth opening is formed on the side of the tension wheel 6. A connecting frame 15 is installed on the side of the chain 3. A support rod 12 is installed on the side of the connecting frame 15 away from the chain 3. A pendant 9 is installed on the support rod 12.

[0022] Furthermore, the pendant 9 has a conical structure, and a hanging groove 10 is formed on the pendant 9. The hanging groove 10 penetrates through one side of the pendant 9. The pendant 9 is hung on the support rod 12 through the hanging groove 10. A support frame 14 is installed on the side of the pendant 9 away from the cone. The support frame 14 is fixedly connected and integrally formed with the pendant 9. A perforation 11 is formed on the support frame 14.

[0023] Furthermore, the tooth openings on the sides of the driven wheels 4 and the tension wheel 6 are all connected to the chain 3, and the plane sides of the driven wheels 4 and the tension wheel 6 are rotationally connected to the supporting mounting frame 5 through a rotating shaft.

[0024] Further, a winding shaft 7 is installed between the driven wheel 4 and the tension wheel 6.
