Description

Technical Field

[0001] This utility model relates to the field of zipper technology, specifically to a zipper dot-cutting mechanism. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items. They are now widely used in clothing, bags, tents, etc. During the manufacturing process, zippers need to be cut to a fixed length to produce zippers of the appropriate size. Currently, zippers are usually made as a whole strip and then cut according to the zipper length.

[0003] Application number CN202121324797.2 discloses a zipper dot-marking and cutting device, including a base, a support, a dot-marking and cutting mechanism, a guide plate, a limiting block, a feeding assembly, and a discharging assembly. The support is mounted on the base, the dot-marking and cutting mechanism is mounted on the support, the guide plate is mounted on the base and below the dot-marking and cutting mechanism, the feeding assembly and the discharging assembly are both mounted on the base, and the feeding assembly and the discharging assembly divide the guide plate into three sections separated by the feeding assembly and the discharging assembly. The feeding assembly and the discharging assembly are respectively located on both sides of the dot-marking and cutting mechanism and are close to the dot-marking and cutting mechanism. The limiting block is movably mounted at the end of the guide plate and is close to the feeding assembly, and the limiting block is configured to cooperate with the guide plate. This utility model belongs to the field of zipper processing technology, specifically referring to a zipper dot-marking and cutting device.

[0004] However, the driven rubber roller of this device is installed at a fixed height, which is not adaptable to bags with zippers of different thicknesses. Some thinner fabric strips or more silky bags will cause insufficient friction and slippage, making it impossible to convey the fabric strip. In addition, the feeding and discharging components are driven by two motors to rotate the active rubber roller. When the feeding and discharging components are in contact with the fabric strip, there may be a speed difference, which may cause the zipper to jam or be stretched and deformed. Therefore, a zipper dotting and cutting mechanism is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a zipper dot-cutting mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is a zipper dotting and cutting mechanism, including a driven rod, a sleeve block movably sleeved in the middle part of the driven rod, a third bearing installed inside the sleeve block, the third bearing sleeved on the outside of the driven rod, the top end of the sleeve block being fixedly connected to the bottom end of a guide rod, the top end of the guide rod passing through the top end of a feeding assembly, a spring sleeved on the outside of the guide rod, the bottom end of the spring being fixedly connected to the top end of the sleeve block, and the top end of the spring being fixedly connected to the inner top of the feeding assembly;

[0007] Both ends of the driven rod are rotatably connected to sliders. A first bearing is installed inside the slider. The first bearing is sleeved on the outer side of both ends of the driven rod. The slider is slidably installed inside the slide groove, which is opened on both sides of the feeding assembly.

[0008] By adopting the above technical solution, the clamping force of the driven rubber wheel can be dynamically adjusted according to the thickness of the belt through the cooperation of the sleeve block, guide rod and spring, so as to avoid the belt from slipping due to being too thin or smooth. The slider and groove design at both ends of the driven rod can buffer pressure changes, ensure that the driven rubber wheel and the driving rubber wheel are in parallel contact, prevent the belt from running off-track and wearing out, and adapt to different types of belts.

[0009] Specifically, the feeding assembly has a fixed base at its inner bottom, an active rod is rotatably mounted inside the base, an active rubber wheel is fixedly sleeved on the outer side of the active rod, a driven rubber wheel is fixedly sleeved on the outer side of the driven rod, and the driven rubber wheel is located directly above the active rubber wheel.

[0010] By adopting the above technical solution, the drive rod is driven to rotate by a motor, which in turn drives the drive rubber wheel to rotate. The driven rubber wheel forms a clamping area with the drive rubber wheel under the pressure of the spring. When the fabric belt passes through this clamping area, the rotation of the two rubber wheels generates frictional forces in opposite directions, driving the fabric belt to be conveyed forward.

[0011] Specifically, a second bearing is sleeved on one end of the active rod, and the second bearing is installed on the inner wall of the feeding assembly.

[0012] By adopting the above technical solution, the second bearing is embedded in the side wall of the feeding assembly, and one end of the driving rod passes through the second bearing and is fixed to its inner ring. When the motor drives the driving rod to rotate, the second bearing reduces the rotational friction resistance, ensuring that the driving rod runs smoothly. The top of the driving rubber wheel protrudes from the top of the base, making it convenient to contact the driven rubber wheel.

[0013] Specifically, a motor is installed on one side of the feeding assembly, the output end of the motor is fixedly connected to one end of the pulley, and the other end of the pulley is fixedly connected to one end of the drive rod.

[0014] Specifically, the pulley is connected to the belt pulley via a belt, and the pulley is rotatably mounted on one side of the discharge assembly.

[0015] By adopting the above technical solution, after the motor starts, its output end directly drives the pulley to rotate. The pulley transmits power to the drive rod through a key connection. Simultaneously, the pulley distributes power to the pulley of the discharge component through the belt, realizing the linkage between the feeding component and the discharge component. This design ensures that after the cloth belt is fed into the feeding end, the discharge end is synchronously pulled, avoiding cloth belt accumulation or uneven tension.

[0016] Specifically, the feeding assembly and the discharging assembly have the same internal structure, and one end of the drive rod inside the discharging assembly is fixedly connected to the center of one end of the pulley.

[0017] By adopting the above technical solution, the feeding component and the discharging component have the same structure, and the two form a "clamping-traction" collaborative mechanism. While the belt is pushed at the feeding end, it is actively pulled out at the discharging end, so as to achieve continuous and stable conveying.

[0018] The beneficial effects of this utility model are:

[0019] The zipper dotting and cutting mechanism described in this utility model, through the cooperation of a sleeve block, a guide rod and a spring, can dynamically adjust the clamping force of the driven rubber wheel according to the thickness of the fabric belt, so as to avoid slippage of the thin or smooth fabric belt; the slider and groove design at both ends of the driven rod can buffer pressure changes, ensure that the driven rubber wheel and the driving rubber wheel are in parallel contact, prevent the fabric belt from running off-center and wearing, and adapt to different types of fabric belts.

[0020] The zipper dotting and cutting mechanism described in this utility model has a feeding component and a discharging component linked by a belt and driven by the same motor. This avoids speed differences caused by two motors and prevents the zipper from jamming or stretching and deforming. The two components form a "clamping-traction" collaborative mechanism to achieve continuous and stable conveying of the fabric belt and ensure the quality of zipper processing.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As one embodiment of this utility model, such as Figures 1-3 As shown, the zipper dotting and cutting mechanism of this utility model includes a driven rod 13, a sleeve block 12 movably sleeved in the middle part of the driven rod 13, a third bearing 16 installed inside the sleeve block 12, the third bearing 16 sleeved on the outside of the driven rod 13, the top end of the sleeve block 12 fixedly connected to the bottom end of the guide rod 4, the top end of the guide rod 4 passing through the top end of the feeding assembly 2, a spring 3 sleeved on the outside of the guide rod 4, the bottom end of the spring 3 fixedly connected to the top end of the sleeve block 12, and the top end of the spring 3 fixedly connected to the inner top of the feeding assembly 2.

[0028] Both ends of the driven rod 13 are rotatably connected to sliders 6. A first bearing 5 is installed inside the slider 6. The first bearing 5 is sleeved on the outer side of both ends of the driven rod 13. The slider 6 is slidably installed inside the slide groove 7. The slide groove 7 is opened on both sides of the inner side of the feeding assembly 2.

[0029] In use, when the zipper tape is fed into the feeding assembly 2, the sleeve 12, via the third bearing 16, allows the driven rod 13 to maintain axial stability during rotation. The guide rod 4 cooperates with the spring 3. When the tape passes between the driven rubber wheel 1 and the driving rubber wheel 11, the spring 3 is compressed, generating downward elastic pressure, which pushes the sleeve 12 and the driven rod 13 downward as a whole, thereby dynamically adjusting the clamping force of the driven rubber wheel 1 on the tape. This elastic adjustment can adapt to tapes of different thicknesses while ensuring maximum friction and preventing slippage due to the tape being too thin or having a smooth surface.

[0030] The sliders 6 at both ends of the driven rod 13 achieve free rotation of the driven rod 13 through the first bearing 5. At the same time, the sliders 6 slide up and down along the slide groove 7. When the thickness of the fabric belt changes or is subjected to external pressure fluctuations, the sliding of the sliders 6 in the slide groove 7 can buffer the pressure changes, so that the driven rubber wheel 1 always maintains parallel contact with the driving rubber wheel 11. The limiting function of the slide groove 7 ensures that the driven rod 13 moves only in the vertical direction, avoiding the fabric belt from running off track or wearing due to skew.

[0031] The present invention also includes an inner bottom fixed base 14 of the feeding assembly 2, an active rod 15 rotatably mounted inside the base 14, an active rubber wheel 11 fixedly sleeved on the outer side of the active rod 15, a driven rubber wheel 1 fixedly sleeved on the outer side of the driven rod 13, and the driven rubber wheel 1 being located directly above the active rubber wheel 11.

[0032] In use, the drive rod 15 is driven to rotate by the motor 9, which drives the drive rubber wheel 11 to rotate. The driven rubber wheel 1 forms a clamping area with the drive rubber wheel 11 under the pressure of the spring 3. When the fabric belt passes through this clamping area, the rotation of the two rubber wheels generates friction in opposite directions, driving the fabric belt to be conveyed forward.

[0033] The present invention also includes a second bearing 8 sleeved at one end of the active rod 15, the second bearing 8 being installed on the inner wall of the feeding assembly 2.

[0034] In use, the second bearing 8 is embedded in the side wall of the feeding assembly 2. One end of the active rod 15 passes through the second bearing 8 and is fixed to its inner ring. When the motor 9 drives the active rod 15 to rotate, the second bearing 8 reduces the rotational friction resistance, ensuring that the active rod 15 operates smoothly. The top of the active rubber wheel 11 protrudes from the top of the base 14, making it easy to contact the driven rubber wheel 1.

[0035] The present invention also includes a motor 9 installed on one side of the feeding assembly 2, the output end of the motor 9 being fixedly connected to one end of the belt pulley 10, and the other end of the belt pulley 10 being fixedly connected to one end of the drive rod 15.

[0036] The present invention also includes that the belt pulley 10 is connected to the pulley 18 via the belt 17, and the pulley 18 is rotatably mounted on one side of the discharge assembly 19.

[0037] When in use, after the motor 9 starts, its output end directly drives the pulley 10 to rotate. The pulley 10 transmits power to the drive rod 15 through a key connection. Simultaneously, the pulley 10 distributes the power to the pulley 18 of the discharge assembly 19 through the belt 17, realizing the linkage between the feeding assembly 2 and the discharge assembly 19. This design ensures that after the fabric belt is fed into the feeding end, the discharge end is synchronously pulled, avoiding fabric belt accumulation or uneven tension.

[0038] The present invention also includes that the internal structure of the feeding component 2 and the discharging component 19 is the same, and one end of the active rod 15 inside the discharging component 19 is fixedly connected to the center of one end of the pulley 18.

[0039] When in use, the feeding component 2 and the discharging component 19 have the same structure and form a "clamping-traction" collaborative mechanism. While the belt is pushed at the feeding end, it is actively pulled out at the discharging end to achieve continuous and stable conveying.

[0040] It should be noted that the dot-cutting mechanism is located between the feeding component 2 and the discharging component 19. For the specific working principle, please refer to the existing mature technologies mentioned in the background technology.

[0041] When this utility model is in use, if the zipper tape needs to be passed between the driven rubber wheel 1 and the driving rubber wheel 11, the motor 9 is started by an external power source. The motor 9 can drive the pulley 10 and the driving rod 15 in the feeding assembly 2 to rotate. The pulley 10 can drive the pulley 18 to rotate through the belt 17. The rotation of the pulley 18 can drive the driving rod 15 in the discharging assembly 19 to rotate. The rotation of the driving rod 15 can drive the driving rubber wheel 11 to rotate. The driving rubber wheel 11 and the driven rubber wheel 1 rotate and squeeze the tape, thereby generating friction that drives the zipper tape to move. In conjunction with the spring 3, the downward pushing force given to the driven rod 13 can increase the friction between the driven rubber wheel 1 and the driving rubber wheel 11, thus avoiding slippage due to insufficient friction for thin tape or silky bags.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
