[0001] The utility model relates to the field of tape wrapping machines, and particularly relates to an adjustable wire inlet mechanism for a tape wrapping machine. Background Art

[0002] In the process of cable production, a tape wrapping machine (wrapping machine) is an indispensable and important device, which is mainly used to tightly wrap various tapes (such as mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around a core wire by rotating a turntable to achieve the insulation or protection function of the cable. In the existing tape wrapping machine technology, the wire inlet mechanism for feeding the core wire into the tape wrapping machine usually adopts a fixed design and cannot adapt to core wires of different sizes, thus limiting the use range and flexibility of the tape wrapping machine. Content of the Utility Model

[0003] The purpose of the utility model is to provide an adjustable wire inlet mechanism for a tape wrapping machine. The mechanism adjusts the interval for adapting to the core wire size between two traction mechanisms through a clamping mechanism, so as to be able to adapt to core wires of different sizes within a certain range.

The clamping mechanism is arranged on the bottom plate and the clamping mechanism drives the two traction mechanisms to move towards each other. The two traction mechanisms clamp the core wire and drive the core wire to move horizontally.

[0006] In the above technical solution, preferably, each traction mechanism includes a synchronous pulley and a transmission belt. Two synchronous pulleys are provided and are horizontally rotatably arranged on the bottom plate from left to right. The transmission belt is sleeved on the two synchronous pulleys.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model and the present utility model is not limited to the following embodiments.

[0019] See Figures 1 - 3 , in this embodiment, an adjustable wire inlet mechanism of a tape wrapping machine includes a bottom plate 1, a traction mechanism 2 and a clamping mechanism 3. Two sets of the traction mechanisms 2 are provided and are symmetrically arranged up and down on the bottom plate 1. The clamping mechanism 3 is arranged on the bottom plate 1, and the clamping mechanism 3 drives the two sets of traction mechanisms 2 to move towards each other. The two sets of traction mechanisms 2 clamp the core wire 4 and drive the core wire 4 to move horizontally.

[0020] When the utility model is used, the core wire 4 is placed between the two sets of traction mechanisms 2, and the clamping mechanism 3 is used to drive the two sets of traction mechanisms 2 to approach and finally clamp the core wire 4 between the two sets of traction mechanisms 2. Then, the traction mechanism 2 is used to drive the core wire 4 to move horizontally, so as to achieve the purpose of feeding the core wire 4 into the tape wrapping machine. Since the interval for adapting to the size of the core wire 4 between the two sets of traction mechanisms 2 in the utility model can be adjusted by the clamping mechanism 3, the utility model can adapt to core wires 4 of different sizes within a certain range, improving the applicable range and flexibility of the tape wrapping machine.

[0021] See Figure 1 , the traction mechanism 2 includes a synchronous pulley 21 and a transmission belt 22. Two synchronous pulleys 21 are provided and are horizontally rotatably arranged on the bottom plate 1 from left to right. The transmission belt 22 is sleeved on the two synchronous pulleys 21, and the clamping mechanism 3 drives the transmission belts 22 in the two sets of traction mechanisms 2 to fit together up and down.

[0022] Place the core wire 4 between the two transmission belts 22, use the clamping mechanism 3 to drive the two transmission belts 22 to approach and fit with the core wire 4, and drive the synchronous pulley 21 to rotate so that the upper and lower transmission belts 22 rotate in opposite directions, thereby driving the core wire 4 to move horizontally to one side by the friction force between the transmission belt 22 and the core wire 4. This traction mechanism 2 facilitates the insertion and removal of the core wire 4, and the transmission belt 22 is usually made of an elastic material (such as rubber) to reduce damage to the core wire 4 when clamping the core wire 4.

[0023] See Figure 1 , the clamping mechanism 3 includes a plurality of electric push rods 31. Two support plates 11 are arranged on the bottom plate 1, and the two support plates 11 are respectively located inside the two transmission belts 22. The plurality of electric push rods 31 are evenly divided into two groups and are symmetrically arranged up and down on the two support plates 11. A push plate 32 is fixed to the telescopic end of the electric push rod 31, and the push plate 32 is attached to the inner side of the transmission belt 22.

[0024] The push plate 32 is driven to move by the electric push rod 31, so that the sides of the two transmission belts 22 are close to each other and fit on the core wire 4 through the action of the push plate 32 in the two transmission belts 22 to achieve clamping. A plurality of electric push rods 31 can strengthen the pushing action of the push plate 32 on the transmission belt 22, improve the uniformity of the pressure on each part of the core wire 4 between the two transmission belts 22, thus ensuring the clamping and traction effect of the transmission belt 22 on the core wire 4 and reducing the occurrence of slipping between the core wire 4 and the transmission belt 22.

[0025] See Figure 2 , a groove body 33 is formed on the push plate 32, an electric heating plate 34 is arranged at the bottom end of the groove body 33, and a plurality of rollers 35 are rotatably arranged in the groove body 33, and the rollers 35 are in contact with the transmission belt 22.

[0026] Since the core wire 4 is in a wound state before entering the taping machine, the bending degree of the core wire 4 will have a certain impact on the taping, reducing the uniformity of the taping. Therefore, in the present utility model, an electric heating plate 34 is arranged in the push plate 32, and the electric heating plate 34 can heat the transmission belt 22 and the core wire 4 in the transmission belt 22 through thermal radiation. Thus, when the core wire 4 is located in the transmission belt 22, it can be heated and the bending degree of the core wire 4 can be reduced through the clamping action of the transmission belt 22, thereby improving the uniformity of the taping when the core wire 4 is pulled into the taping machine and improving the quality of the taping of the core wire 4. When the transmission belt 22 moves, it drives the rollers 35 to rotate, reducing the friction between the transmission belt 22 and the push plate 32 and ensuring the normal rotation of the transmission belt 22.

[0027] See Figure 1 , a vertically arranged sliding groove 12 is formed on the bottom plate 1, and two sliders 51 are arranged on the sliding groove 12 to slide up and down through the drive of a lead screw motor 5. A tension pulley 52 is rotatably arranged on the front side of the slider 51, and the two tension pulleys 52 are respectively located in the two transmission belts 22.

[0028] When the transmission belt 22 is sleeved on the two synchronous pulleys 21, the slider 51 can be driven to move through the lead screw motor 5, so that the transmission belt 22 is tensioned through the tension pulley 52, reducing the occurrence of the transmission belt 22 being loose and falling off the synchronous pulley 21 during installation. When the clamping mechanism 3 drives one side of the transmission belt 22 to move into contact with the core wire 4, since the tension pulley 52 and the push plate 32 act on the upper and lower sections of the transmission belt 22 respectively, the tension degree of the transmission belt 22 can be reduced through the action of the lead screw motor 5 and the tension pulley 52 at this time so that the clamping mechanism 3 can drive the transmission belt 22 to move.

[0029] When the core wire 4 has different sizes, the tension force exerted by the push plate 32 on the transmission belt 22 is different. The tension force of the transmission belt 22 can be adjusted by adjusting the tension pulley 52 so that the transmission belt 22 can maintain an appropriate tension range when used for core wires 4 of different sizes, ensuring that the transmission belt 22 can rotate normally under the action of the synchronous pulley 21 and thus drive the movement of the core wire 4.

[0030] See Figure 3 A screw rod 53 of the screw rod motor 5 is provided with two threads with opposite spiral directions, and two sliders 51 are respectively threadedly connected to the two threads.

[0031] The screw rod 53 is driven to rotate by the screw rod motor 5, thereby driving the two sliders 51 to move towards each other simultaneously, reducing the number of screw rod motors 5 required. At the same time, it is convenient to adjust the tension of the two transmission belts 22 simultaneously, ensuring that the tensions of the two transmission belts 22 are roughly the same, thus ensuring the clamping and traction effect on the transmission belt 22.

[0032] See Figure 3 A driving motor 6 is provided at the rear side of the bottom plate 1. The driving motor 6 is connected to any one of the synchronous pulleys 21 and drives the synchronous pulley 21 to rotate. Two gears 61 are coaxially fixed to the two synchronous pulleys 21 that are close to each other vertically in the two traction mechanisms 2. The two gears 61 are located at the rear side of the bottom plate 1 and are in meshing transmission.

[0033] In the present utility model, the synchronous pulley 21 connected to the driving motor 6 is driven to rotate by the driving motor 6. The synchronous pulley 21 drives another synchronous pulley 21 in the same traction mechanism 2 to rotate through the transmission belt 22. Furthermore, another synchronous pulley 21 drives another traction mechanism 2 to operate through the meshing transmission of the gear 61. Thus, the present utility model drives the two traction mechanisms 2 to operate simultaneously by one driving motor 6, reducing the number of driving motors 6 required for driving. At the same time, it ensures that the two transmission belts 22 rotate in opposite directions at the same speed, ensuring the clamping and traction effect of the transmission belt 22 on the core wire 4.
