Description

Technical Field

[0001] The utility model relates to the field of taping machines, in particular to an active transmission structure of a taping machine. Background Art

[0002] In the cable production process, the taping machine (wrapping machine) is an indispensable and important equipment. It is mainly used to tightly wrap various tapes (such as mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around the core wire through a rotating disk to achieve the insulation or protection function of the cable.

[0003] The working process of the existing taping machine is to pass the core wire through the wrapping shaft. The taping disk and the wrapping mechanism are respectively arranged at the left and right ends of the wrapping shaft. The tape is unrolled and pulled out from the taping disk and passed through the wrapping shaft and then installed on the wrapping mechanism. The wrapping shaft is driven to rotate to realize the tape wrapping around the core wire. The existing taping machine usually uses a servo motor to drive the wrapping shaft to rotate through a belt drive. The belt is attached to the left and right sides of the wrapping shaft. Since the wrapping shaft has a certain length, it is easy to produce a slight deviation when the wrapping shaft rotates, causing shaking, resulting in the wrapping shaft being prone to loosening and wear after a long period of rotation. Utility Model Content

[0004] The purpose of the utility model is to provide an active transmission structure of a tape wrapping machine, which drives two belts respectively attached to the front and rear sides of the wrapping shaft through a driving motor to drive the wrapping shaft to rotate, thereby reducing the horizontal deviation and shaking of the wrapping shaft, and can reduce the probability of loosening and wear of the wrapping shaft.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0019] See also Figure 1-Figure 3The present embodiment is an active transmission structure of a tape wrapping machine, comprising a frame 1, a wrapping shaft 2, a belt 3 and a driving motor 4. The wrapping shaft 2 is rotatably arranged on the upper side of the frame 1, and two belts 3 are arranged and respectively fit with the front and rear sides of the wrapping shaft 2. The two belts 3 are sleeved on the rotating shaft of the driving motor 4 through a guide wheel group 5.

[0020] The utility model drives two belts 3 to rotate simultaneously through a driving motor 4, and the belts 3 are connected to the wrapping shaft 2 through a guide wheel set 5, so that the wrapping shaft 2 is driven to rotate by the driving motor 4 to realize the normal operation of the taping machine. Since the two belts 3 in the utility model are respectively attached to the front and rear sides of the wrapping shaft 2, the decomposition of the forces generated by the two belts 3 on the wrapping shaft 2 in the horizontal direction can offset each other, thereby reducing the horizontal deviation and shaking of the wrapping shaft 2, and reducing the probability of loosening and wear of the wrapping shaft 2.

[0021] At the same time, compared with the existing method of using two drive motors 4 to drive two belts 3 respectively, the utility model drives the two belts 3 through a single drive motor 4 through a guide wheel group 5, which reduces the complexity of the equipment and can ensure that the rotational speeds of the two belts 3 remain consistent, thereby achieving a better driving effect on the wrapping shaft 2.

[0022] See also Figure 1 , Figure 2 The guide wheel group 5 includes four guide wheels 51 rotatably arranged on the frame 1, wherein two guide wheels 51 are arranged on the front side of the frame 1 through a mounting bracket 52, and the other two guide wheels 51 are arranged on the rear side of the frame 1 through another mounting bracket 52. The driving motor 4 is arranged on the lower side of the frame 1, and the two belts 3 are respectively wound around the guide wheels 51 on the front and rear sides of the frame 1.

[0023] By installing the wrapping shaft 2 on the upper side of the frame 1 and installing the driving motor 4 on the lower side of the bracket, the wrapping shaft 2 is raised to facilitate the workers to thread the wire and tape on the wrapping shaft 2. At the same time, the cavity on the lower side of the frame 1 can be effectively utilized, making the structure of the entire tape wrapping machine equipment more compact and reducing the space occupied by the equipment.

[0024] See also Figure 1 , Figure 2 A first pulley 21 is coaxially sleeved on the wrapping shaft 2, a second pulley 41 is coaxially fixed on the rotating shaft of the driving motor 4, and the belt 3 is sleeved on the first pulley 21 and the second pulley 41 at the same time.

[0025] The first pulley 21 and the second pulley 41 can reduce the probability of slipping between the belt 3 and the drive motor 4 and the wrapping shaft 2, and at the same time reduce the risk of the belt 3 sliding horizontally on the rotating shaft of the wrapping shaft 2 and the drive motor 4, thereby ensuring the stability of the drive motor 4 driving the wrapping shaft 2 to rotate through the belt 3.

[0026] See also Figure 1 Two first bearing seats 11 are sleeved and fixed on the winding shaft 2. The two first bearing seats 11 are respectively close to the left and right ends of the winding shaft 2. The first bearing seats 11 are fixed on the frame 1.

[0027] The bearing seat supports the wrapping shaft 2 , reduces the friction resistance of the wrapping shaft 2 during rotation, improves the smoothness and stability of the wrapping shaft 2 during rotation, improves the output efficiency of the driving motor 4 , and reduces the friction and wear of the wrapping shaft 2 .

[0028] See also Figure 3 The mounting bracket 52 is provided with a sliding hole 53, in which a second bearing seat 54 is rotatably arranged. Two guide wheels 51 located at the front and rear sides of the frame 1 and farther away from the frame 1 are rotatably arranged in the second bearing seat 54, and the second bearing seat 54 is fixed in the sliding hole 53 by an adjusting mechanism 6.

[0029] The tension of the belt 3 is adjusted by adjusting the position of the second bearing seat 54 in the sliding hole 53 , and the looseness is reduced, resulting in a reduction in the force between one of the belts 3 and the wrapping shaft 2 , so that the wrapping shaft 2 is unevenly stressed.

[0030] In this embodiment, two sliding holes 53 and two second bearing seats 54 are provided, and the left and right ends of the guide wheel 51 are respectively connected to the two second bearing seats 54, and the two second bearing seats 54 are respectively slidably set in the two sliding holes 53, so that the guide wheel 51 remains parallel to the wrapping axis 2 while adjusting the front and rear position of the guide wheel 51.

[0031] The utility model drives the second bearing seat 54 to move horizontally forward and backward along the sliding hole 53, so that the guide wheel 51 arranged in the second bearing seat 54 moves forward and backward. Since the positions of the wrapping shaft 2 and the driving motor 4 remain unchanged, the tension of the belt 3 wound on the guide wheel 51 can be adjusted, so that the belt 3 can fit tightly between the first pulley 21 and the second pulley 41, thereby ensuring the transmission effect between the belt 3 and the driving motor 4 and the wrapping shaft 2. At the same time, the two belts 3 can be adjusted to the same tension value as much as possible, so that the forces acting on the wrapping shaft 2 by the two belts 3 are as similar as possible, thereby reducing the horizontal deviation and shaking of the wrapping shaft 2.

[0032] See also Figure 3The adjustment mechanism 6 includes a latch 61 and a socket 62 . A plurality of sockets 62 are provided and are arranged in parallel on the mounting bracket 52 . The latch 61 is inserted through the socket 62 and the second bearing seat 54 at the same time.

[0033] Multi-level adjustment of the tension of the belt 3 is achieved through a plurality of parallel sockets 62, and the fixing method using the latch 61 and the socket 62 can prevent the second bearing seat 54 from sliding in the slide hole 53 due to loosening, thereby improving the stability of the utility model during use. At the same time, quick adjustment can be achieved by inserting and removing the latch 61, thereby improving the convenience of adjusting the tension of the belt 3.

[0034] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
