Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of zipper production equipment, in particular to a zipper tension adjusting transmission mechanism. Background Art
[0002] A zipper is a connecting piece that relies on continuously arranged teeth to join or separate items, and is widely used in clothing, bags, tents, etc. During the production process of the zipper tape, it needs to go through multiple steps. During this process, the zipper tape will appear wrinkled and become uneven. Therefore, it is necessary to flatten the zipper tape. Generally, a ironing machine is used for flattening the zipper tape. Traditional ironing machines can flatten the zipper tape, but during the process of ironing the zipper tape flat, the zipper will be stretched and deformed, and it will shrink again during the subsequent production process, which is called the weaving shrinkage rate in the industry. And this kind of shrinkage is irreversible. If the shrinkage problem is not paid attention to, it will affect the quality and stability of the finished zipper tape, resulting in damage to the zipper tape, incomplete shaping, and inability to meet the design requirements for later use. Now, ironing machines tighten the zipper tape to keep it in a taut state and then iron and shape it through the ironing machine without pre-shrinking treatment. Such a method is likely to cause the zipper tape to break or fail to shrink and shape, which will also affect the quality and shaping stability of the finished zipper tape. Therefore, how to pre-shrink the zipper while flattening the zipper tape to ensure its quality and stability is a technical problem urgently needed to be solved in the current industry. Content of the Utility Model
[0003] The utility model aims to provide a zipper tension adjusting transmission mechanism to ensure the purpose of pre-shrinking while effectively flattening the zipper tape.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A zipper tension adjusting transmission mechanism includes a frame. The frame is sequentially provided with an inlet tape guide wheel, a front transmission structure, a tension adjusting structure, a rear transmission structure, and an outlet tape structure in the tape feeding direction. Both the front transmission structure and the rear transmission structure include two transmission rollers correspondingly arranged on the upper and lower / left and right sides inside the frame. The tension adjusting structure includes a driving tape running wheel and a driven wheel. The outer side of the driving tape running wheel has a tape running curved surface for the zipper tape to pass through. The driven wheel is arranged on the tape running curved surface, and the pressure of the driven wheel acting on the driving tape running wheel is adjusted by an adjusting screw rod to tension or relax the zipper tape entering the transmission structure.
[0005] Further, both the front transmission structure and the rear transmission structure adopt a long-wrap tape running method and are commonly connected to a first power device. Both of the transmission rollers are rotatably connected to the frame, and a tape deflecting assembly is arranged between the two transmission rollers.
[0006] Further, there are two driven wheels, and the two driven wheels are arranged on the left and right sides of the driving belt wheel. Each of the two driven wheels includes an L-shaped frame and a first roller. The two L-shaped frames are arranged oppositely, and the corners of the two L-shaped frames are connected by a rotating pin. The first roller is rotatably arranged at one end of the L-shaped frame. The adjusting screw rods are commonly connected to the other ends of the two L-shaped frames. The adjusting screw rods are provided with springs, and the springs are located between the two L-shaped frames.
[0007] Further, the belt output structure includes a driving belt output wheel and a second roller. The second roller is arranged on the driving belt output wheel through a connecting main frame.
[0008] Further, both the driving belt wheel and the driving belt output wheel are connected to a second power device.
[0009] Further, a plurality of inlets and outlets are provided on the machine frame, and belt passing wheels are arranged at the front end or the rear end of the inlets and outlets according to the belt feeding direction.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The zipper tape passes through the machine frame. By using the tension adjusting device to apply pressure to the zipper tape, the zipper tape located on the front transmission structure is tightened. Then the zipper tape passes through the rear transmission structure and the belt output structure to be output, so that the zipper tape can naturally contract in the rear transmission structure, avoiding the zipper tape being always in a taut state when passing through the ironing machine, facilitating the full contraction and shaping of the zipper tape, preventing damage to the zipper tape, and ensuring the quality and stability of the zipper tape.

Detailed implementation manners
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] As shown in the accompanying drawings, a zipper tension adjustment and transmission mechanism of the present invention includes a frame 1. The frame 1 is arranged from front to back in the tape inlet direction of the zipper tape, and is provided with a tape inlet guide pulley 2, a front drive structure 4a, a tension adjustment structure 3, a rear drive structure 4b, and a tape outlet structure 5. The front drive structure 4a or the rear drive structure 4b can be respectively set to one group or more, such as Figure 5As shown, there are two sets of front drive structures 4a, one set of rear drive structures 4b, and one tension adjustment structure 3. The tape feed guide pulley 2 is used to guide the zipper tape into the machine frame 1. The zipper tape winds around the front drive structure 4a inside the machine frame 1, then passes through the tension adjustment structure 3. The tension adjustment structure 3 provides power for the transportation of the zipper tape at the same speed as the front drive structure 4a and provides tension for the zipper tape to hold and tighten the zipper tape located between the front drive structure 4a and the tension adjustment structure 3. After passing through the tension adjustment structure 3, the zipper tape winds around the rear drive structure 4b and is finally output via the tape output structure 5. It should be noted that the transportation of the zipper tape is driven by the front drive structure 4a and the rear drive structure 4b. Both the front drive structure 4a and the rear drive structure 4b include two drive rollers 41 correspondingly arranged on the upper and lower or left and right sides inside the machine frame 1. The two drive rollers 41 are common structures in the existing ironing machine structure. It should be noted that the drive structure is divided into two parts, front and rear, and is divided by the tension adjustment structure 3. The front drive structure 4a and the rear drive structure 4b belong to the same structure. The zipper tape is a long tape structure that winds around several drive rollers 41 in sequence. The two drive rollers 41 hold the zipper tape on both sides, causing the zipper tape to be tensioned and contracted within the transportation area between the two drive rollers 41. The zipper tape in the front drive structure 4a is in a tensioned state and cooperates with the ironing machine to provide flat ironing treatment for this part of the zipper tape. The zipper tape in the rear drive structure 4b is relatively loose compared to the zipper tape in the front drive structure 4a, providing sufficient space for the pre-shrinking of the zipper tape. At the same time, people can clearly feel that the tension of the zipper tape wound around the front drive structure 4a is greater than the tension of the zipper tape wound around the rear drive structure 4b. The long tape structure of the zipper tape needs to complete flat ironing and pre-shrinking treatment inside the machine frame 1. Setting two drive structures facilitates dividing into at least two areas, enabling the zipper tape to complete flat ironing and pre-shrinking treatment in different areas. The tension adjustment structure 3 includes a driving tape running wheel 31 and a driven wheel 32. The outer side of the driving tape running wheel 31 has a tape running surface 310 for the zipper tape to pass through. The driven wheel 32 is arranged on the tape running surface 310, and the pressure of the driven wheel 32 acting on the driving tape running wheel 31 is adjusted by an adjusting screw 33 to change the pulling force of the zipper tape, enabling it to adjust the optimal pulling force according to different situations. That is, the zipper tape passes between the driving tape running wheel 31 and the driven wheel 32. The rotation of the driving tape running wheel 31 drives the zipper tape to move, and the driven wheel 32 applies pressure to the zipper tape, thus keeping the zipper tape in a taut state. The zipper tape at the rear of the tension adjustment structure 3 is transported out of the tape by the tape output structure 5 and is not subjected to the tension pressure, so that the zipper tape is in different tension force states in the front and rear two areas of the tension adjustment structure 3. At the same time, the transportation speeds of the front drive structure 4a and the rear drive structure 4b are equal, and the tension adjustment structure 3 and the tape output structure 5 can maintain the same progressive speed as the drive structure, maintaining the tape supply balance of the zipper tape at the same speed and preventing the zipper tape from being too loose in the drive structure.
[0019] The utility model discloses a zipper tension regulating transmission mechanism, wherein the zipper belt passes through a frame 1, and a tension regulating structure 3 is used to apply pressure to the zipper belt so that the zipper belt located on a front transmission structure 4a is tensioned, and then the zipper belt passes through a rear transmission structure 4b and a belt output structure 5 to be output, so that the zipper belt can shrink naturally in the rear transmission structure 4b, thereby avoiding the zipper belt from maintaining excessive tension while passing through an ironing machine, facilitating the zipper belt to fully shrink and shape, preventing the zipper belt from being damaged, and ensuring the quality and stability of the zipper belt.
[0020] In this embodiment, the transmission structure adopts a long winding belt method that is wound up and down / left and right, and is commonly connected to the first power device 34, which can be realized by a drive motor. The zipper is a continuous long belt structure during production. Figure 5 , the specific order of winding the zipper tape on the transmission structure is that the zipper tape is progressively wound around adjacent transmission rollers 41 in the length direction of the frame 1, and the transmission rollers 41 are rotatably connected to the frame 1, and a belt pulling assembly 411 is also arranged between the two corresponding transmission rollers 41. The belt pulling assembly 411 also includes a first belt pulling assembly and a second belt pulling assembly. While the zipper tape is progressively advanced left and right, the belt pulling assembly 411 is used to realize the advancement from back to front in the thickness direction of the frame 1. Reference may be made to the supply and winding direction of the zipper tape in the existing ironing machine.
[0021] In this embodiment, two driven wheels 32 are provided, and the two driven wheels 32 are provided on the left and right sides of the active belt-walking wheel 31. The two driven wheels 32 each include an L-shaped frame 322 and a first roller 321. The two L-shaped frames 322 are provided opposite to each other. The specific shape of the L-shaped frame 322 is as follows: Figure 3 , forming “>” and “<” symbols, the corners of the two L-shaped frames 322 are connected by a turn pin 323, the first roller 321 is rotatably set at one end of the L-shaped frame 322, and the adjusting screw 33 is commonly connected to the other end of the two L-shaped frames 322, the adjusting screw 33 is penetrated by a spring 331, and the spring 331 is located between the two L-shaped frames 322, and is rotatably connected through a turn pin 323, the first roller 321 is rotatably set at one end of the L-shaped frame 322 near the bottom, the two L-shaped frames 322 are both provided with a connecting rod, and the two connecting rods are commonly connected by an adjusting screw 33, the spring 331 on the adjusting screw 33 is mainly used to keep the ends of the two L-shaped frames 322 near the top relatively open, so as to ensure that the first roller 321 at the bottom is kept under a certain pressure to act on the passing zipper tape, it should be noted that, with reference to Figure 3 The midpoint between the two L-shaped frames 322 and the center point of the active belt-walking wheel 31 are on the same vertical line, and the two first rollers 321 are located on the left and right sides of the upper part of the active belt-walking wheel 31.
[0022] In this embodiment, the tape-out structure 5 includes a driving tape-out wheel 51 and a second roller 52. The second roller 52 is arranged on the driving tape-out wheel 51 through a connecting main frame 53. The pressure of the tape-out structure 5 is less than that of the tension adjusting structure 3. The second roller 52 on the tape-out structure 5 is mainly used to cooperate with the driving tape-out wheel 51 to realize the function of sending out the zipper tape. The tape-out structure 5 and its function belong to the existing structure, and reference can be made to the tape-out structure 5 of the existing zipper tape. It should be noted that the pressure exerted by the second roller 52 on the part of the zipper tape located on the driving tape-out wheel 51 must be less than the pressure exerted by the first roller 321 on the part of the zipper tape located on the driving tape-running wheel 31, so as to avoid the same tension force at both ends of the zipper tape entering and leaving the machine frame 1. Both the driving tape-running wheel 31 and the driving tape-out wheel 51 are connected with a second power device 35. The second power device 35 can adopt existing devices such as a servo motor and a speed reducer that can drive the driving tape-running wheel 31 / the driving tape-out wheel 51 to make a rotational motion. The tension adjusting structure 3 adopts the torque mode of the servo motor. (In this mode, no matter how fast the speed of the front transmission structure 4a is, the tension adjusting structure always has a corresponding force to pull the zipper tape, so that the zipper tape is in a taut state.) Further explanation, the front transmission structure 4a and the rear transmission structure 4b maintain the same conveying speed under the drive of the same first power device 34. The speeds of the tension adjusting structure 3 and the tape-out structure 5 also remain the same and are equal to the conveying speed of the front transmission structure 4a. The progressive transportation of the zipper tape mainly depends on the front transmission structure 4a and the rear transmission structure 4b. The tension adjusting structure 3 and the tape-out structure 5 can also convey the zipper tape, so that the zipper tape can pass through the machine frame 1.
[0023] In this embodiment, a plurality of inlets and outlets 100 are provided on the machine frame 1. The plurality of inlets and outlets 100 can be referred to in the appendix Figure 1 , 2 and 5. One is arranged on the left side of the machine frame 1 to provide the zipper tape for use. The other is arranged on the right side of the machine frame 1 to provide the zipper tape for sending out to the tape-out structure for use. Another inlet and outlet 100 is located corresponding to the tension adjusting structure 3, which is convenient for the zipper tape to enter and leave the machine frame 1 and wind around the tension adjusting structure 3. The tension adjusting structure 3 is arranged outside the machine frame 1 mainly to facilitate the operation and maintenance of workers. The tension adjusting structure 3 can also be installed inside the machine frame 1. The inlet and outlet 100 is provided with a tape-passing wheel 101 at the front end or the rear end in the tape-in direction, which is more convenient for the transmission connection between the two structures before and after the inlet and outlet 100. The tape-passing wheel 101 can ensure the smoothness of the zipper tape passing through the inlet and outlet 100.
[0024] In summary, the zipper tape is introduced into the frame 1 from the tape inlet guide pulley 2, wound around the front drive structure 4a, then wound out of the frame 1, passes through the tension adjusting structure 3, passes through the tape running surface 310 of the driving tape running pulley 31, and then enters the frame 1 through the inlet and outlet 100. The zipper tape that enters the frame 1 again is wound around the rear drive structure 4b, and finally passes through another inlet and outlet 100 to the tape outlet structure 5 outside the frame 1. The driving tape outlet pulley 51 and the second roller 52 of the tape outlet structure 5 cooperate to guide the zipper tape out. The conveying speed of the zipper tape remains synchronized throughout the process. The zipper tape passes through the tape running surface 310 of the driving tape running pulley 31, and the two driven pulleys 32 press the zipper tape on the tape running surface 310. Without affecting the conveying speed of the zipper tape, the tension adjusting structure 3 applies pressure to the zipper tape, tightens the zipper tape located on the front drive structure 4a, so that one end of the zipper tape is tightened to cooperate with the ironing tape treatment, thereby making the zipper tape flat. And the tension adjusting structure 3 does not affect the rear drive structure 4b. Therefore, the pulling force of the zipper tape on the rear drive structure 4b is small, avoiding affecting the shrinkage and shaping of the zipper tape.
[0025] The above embodiments are the preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made shall fall within the protection scope of the present invention.
