Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of zipper tape processing equipment, and relates to a zipper tape pre-expansion machine. Background Technology
[0002] During the production and processing of zipper tape, a pre-expansion machine is required to transport the zipper tape and straighten it.
[0003] Regarding the working principle of the pre-expansion machine, please refer to the patent document with application number 202220337587.5, which provides a zipper tape pre-expansion machine. It includes a transmission roller device, which is set on the worktable and includes at least two sets of transmission roller assemblies arranged sequentially at intervals along the conveying direction of the zipper tape. Each set of transmission roller assemblies includes a first transmission roller and a second transmission roller located above the first transmission roller. The first transmission roller and the second transmission roller act on the upper and lower sides of the zipper tape to be processed, thereby conveying the zipper tape forward. The transmission roller assembly located in front drives the zipper tape forward at a speed greater than the transmission roller assembly located behind drives the zipper tape forward.
[0004] The lateral spacing between the drive rollers is used to allow the zipper to pass through. In the prior art, this spacing is fixed. When the zipper on the zipper belt is large, the drive rollers are prone to crushing the zipper. Summary of the Invention
[0005] This utility model addresses the aforementioned problems in the existing technology by providing a zipper belt pre-expansion machine. The technical problem to be solved by this utility model is: how to adjust the interval between the rollers.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A zipper tape pre-expansion machine includes a frame, on which a first mounting seat and a second mounting seat are provided. The first mounting seat is provided with a first driving roller and a second driven roller that can be linked together. The second mounting seat is provided with a second driving roller and a second driven roller that can be linked together. The frame also includes a driving component for driving the first driving roller to rotate. The machine is characterized in that the first mounting seat and / or the second mounting seat are movably mounted on the frame, and a spline connects the first and second driving rollers, allowing the first or second driving roller to move relative to the spline.
[0008] In this zipper belt pre-expansion machine, drive component one drives drive roller one to rotate, drive roller one drives driven roller one to rotate, and drive roller one drives drive roller two to rotate through splines. Drive roller two drives driven roller two to rotate. The synchronously rotating drive roller one and driven roller one press one side of the zipper belt and drive the zipper belt forward. The synchronously rotating drive roller two and driven roller two press one side of the zipper belt and drive the zipper belt forward. Drive roller one and drive roller two are arranged opposite each other and there is a gap between them. Drive roller one and driven roller two are also arranged opposite each other and there is a gap between them. The zipper on the zipper belt passes through the gaps mentioned above.
[0009] By driving the first mounting base to move, or driving the second mounting base to move, or driving both mounting bases to move, the horizontal spacing between the first and second active rollers and the second driven roller can be adjusted. The spacing can be adjusted according to the size of the zipper on the zipper belt, providing good adaptability and effectively preventing the zipper from being damaged.
[0010] The spline can be fixed on the first drive roller, in which case the spline moves relative to the second drive roller; or the spline can be fixed on the second drive roller, in which case the spline moves relative to the first drive roller.
[0011] In the aforementioned zipper tape pre-expansion machine, the spline includes a cylindrical shaft with several bosses on its outer wall. The bosses extend axially along the shaft and are evenly distributed circumferentially along the shaft. The ends of the first and second drive rollers are respectively provided with receiving grooves adapted to the shape of the spline. One end and the other end of the spline are respectively connected to the receiving groove of the first drive roller and the receiving groove of the second drive roller.
[0012] The bosses can increase the strength of the spline. After the spline is installed on the drive roller, it can also limit the spline in the circumferential direction. There are two or more bosses, which are evenly distributed in the circumferential direction of the shaft. During transmission, the spline can be subjected to more balanced force.
[0013] In the aforementioned zipper tape pre-expansion machine, the driving component one includes a motor, which is mounted on a mounting base one. A gear one is mounted on the output shaft of the motor. A gear two and a gear three are mounted on one end of the driving roller shaft one. A gear four is mounted on one end of the driving roller shaft one. A gear five is mounted on one end of the driving roller shaft two. A gear six is mounted on one end of the driven roller shaft two. Gear one meshes with gear two, gear three meshes with gear four, and gear five meshes with gear six.
[0014] When the motor rotates, gear one on the output shaft drives gear two to rotate, thereby causing the drive roller shaft one to rotate. Gear three rotates with the drive roller shaft one, and gear three drives gear four to rotate, thereby causing the driven roller shaft one to rotate. This achieves linkage between the drive roller shaft one and the driven roller shaft one. At the same time, the drive roller shaft one drives the drive roller shaft two to rotate through the spline. Gear five on the drive roller shaft two rotates, and gear five drives gear six to rotate, thereby causing the driven roller shaft two to rotate. This achieves linkage between the drive roller shaft two and the driven roller shaft two.
[0015] This structure uses a single motor to drive four rollers to rotate synchronously, which simplifies the structure and saves space for the entire device.
[0016] In the aforementioned zipper tape pre-expansion machine, a connecting block 1 is mounted on the mounting base 1, a connecting block 2 is disposed above the connecting block 1, and a driving component 2 for driving the connecting block 2 to move up and down is also disposed on the mounting base 1. An active roller shaft 1 and a driven roller shaft 1 are respectively mounted on the connecting block 1 and the connecting block 2. A connecting block 3 is mounted on the mounting base 2, a connecting block 4 is disposed above the connecting block 3, and a driving component 2 for driving the connecting block 4 to move up and down is also disposed on the mounting base 2. The active roller shaft 2 and the driven roller shaft 2 are respectively mounted on the connecting block 3 and the connecting block 4.
[0017] One drive component two drives the connecting block two to move up and down, which can adjust the interval between the driven roller shaft one and the driving roller shaft one in the vertical direction. Another drive component two drives the connecting block four to move up and down, which can also adjust the interval between the driven roller shaft two and the driving roller shaft two in the vertical direction. This structure can adjust the interval according to the thickness of the zipper head on the zipper belt, which has good adaptability. When the zipper head passes through, the drive component two drives the driven roller shaft one and the driven roller shaft two to lift upwards respectively, so that the zipper head can pass smoothly and effectively avoid the zipper head being crushed.
[0018] In the aforementioned zipper tape pre-expansion machine, the second driving component includes a cylinder, and the second connecting block and the fourth connecting block are respectively mounted on the piston rods of the corresponding cylinders.
[0019] In other embodiments, the cylinder can also be replaced by a hydraulic cylinder or a linear motor.
[0020] In the aforementioned zipper tape pre-expansion machine, a connecting rod is installed on one side of the connecting block two, a fixing block is installed on one side of the connecting rod, and the piston rod of the cylinder is connected to the fixing block.
[0021] In this structure, connecting block two is mounted on the piston rod of the cylinder via a fixed connecting rod and a fixing block.
[0022] In the aforementioned zipper belt pre-expansion machine, the first driving component, the first active roller, the first driven roller, the second active roller, and the second driven roller constitute a zipper belt conveying mechanism. There are two zipper belt conveying mechanisms arranged one in front of the other. The rotational speed of the first driving component on the rear zipper belt conveying mechanism is less than the rotational speed of the first driving component on the front zipper belt conveying mechanism.
[0023] Two zipper belt conveyor mechanisms are arranged side by side in the front and rear direction of the frame. They work together to convey the zipper belt. The drive components on the two zipper belt conveyor mechanisms rotate at different speeds. The conveying speed of the rear zipper belt conveyor mechanism is lower than that of the front zipper belt conveyor mechanism. This allows the front zipper belt conveyor mechanism to tighten the zipper belt during the conveying process, thus achieving pre-expansion of the zipper belt.
[0024] Compared with the prior art, the advantages of this utility model are as follows:
[0025] 1. This zipper belt pre-expansion machine can adjust the horizontal spacing between rollers according to the size of the zipper on the zipper belt, which has good adaptability and avoids the zipper being crushed.
[0026] 2. This zipper belt pre-expansion machine can adjust the vertical spacing between the rollers according to the thickness of the zipper head on the zipper belt. When the zipper head passes through, the driving component two drives the driven roller one and driven roller two to lift upwards respectively, so that the zipper head can pass through smoothly and avoid the zipper head being crushed.

Detailed Implementation
[0032] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0033] like Figure 1-4 As shown, this zipper tape pre-expansion machine includes a frame 1, on which a mounting base 2 and a mounting base 3 are provided. Mounting base 2 is provided with a drive roller 4 and a driven roller 5 that can be linked together. Mounting base 3 is provided with a drive roller 6 and a driven roller 7 that can be linked together. The frame 1 is also provided with a drive component 8 that drives the drive roller 4 to rotate. Mounting base 2 and / or mounting base 3 are movably mounted on the frame 1. A spline 9 connects the drive roller 4 and the drive roller 6, and the drive roller 4 or the drive roller 6 can move relative to the spline 9.
[0034] In this zipper belt pre-expansion machine, drive component 8 drives drive roller 4 to rotate, drive roller 4 drives driven roller 5 to rotate, and drive roller 4 drives drive roller 6 to rotate through spline 9. Drive roller 6 drives driven roller 7 to rotate. The synchronously rotating drive roller 4 and driven roller 5 press one side of the zipper belt and drive the zipper belt forward. The synchronously rotating drive roller 6 and driven roller 7 press the other side of the zipper belt and drive the zipper belt forward. Drive roller 4 and drive roller 6 are arranged opposite each other and there is a gap between them. Drive roller 5 and driven roller 7 are arranged opposite each other and there is also a gap between them. The zipper on the zipper belt passes through the above-mentioned gap.
[0035] By driving the mounting base 12 to move, or driving the mounting base 23 to move, or driving both mounting base 12 and mounting base 23 to move, the horizontal spacing between the active roller 14 and the active roller 26, as well as the horizontal spacing between the driven roller 15 and the driven roller 27, can be adjusted. The spacing can be adjusted according to the size of the zipper on the zipper belt, providing good adaptability and effectively preventing the zipper from being damaged.
[0036] The driving source can be a cylinder. When the piston rod of the cylinder extends or retracts, it drives the mounting seat 2 or mounting seat 3 to move. When the piston rod is stationary, the mounting seat 2 or mounting seat 3 is positioned on the frame 1.
[0037] Spline 9 can be fixed on drive roller 4, in which case spline 9 moves relative to drive roller 6; or spline 9 can be fixed on drive roller 6, in which case spline 9 moves relative to drive roller 4.
[0038] like Figure 4As shown, in this embodiment, the spline 9 includes a cylindrical shaft 10. The outer wall of the shaft 10 has a plurality of bosses 11. The bosses 11 extend along the axial direction of the shaft 10 and are evenly distributed along the circumference of the shaft 10. The ends of the first drive roller shaft 4 and the second drive roller shaft 6 are respectively provided with receiving grooves (not shown) adapted to the shape of the spline 9. One end and the other end of the spline 9 are respectively connected in the receiving groove of the first drive roller shaft 4 and the receiving groove of the second drive roller shaft 6.
[0039] The boss 11 can increase the strength of the spline 9. After the spline 9 is installed on the drive roller, it can also limit the spline 9 in the circumferential direction. There are two or more bosses 11, which are evenly distributed in the circumferential direction of the shaft 10. During transmission, the spline 9 can be subjected to more balanced force.
[0040] like Figure 3 As shown, in this embodiment, the driving component 8 includes a motor 12, which is mounted on the mounting base 2. A gear 13 is mounted on the output shaft of the motor 12. A gear 2 14 and a gear 3 15 are mounted on one end of the driving roller shaft 4. A gear 4 16 is mounted on one end of the driven roller shaft 5. A gear 5 17 is mounted on one end of the driving roller shaft 2 6. A gear 6 18 is mounted on one end of the driven roller shaft 2 7. Gear 13 meshes with gear 2 14, gear 3 15 meshes with gear 4 16, and gear 5 17 meshes with gear 6 18.
[0041] When motor 12 rotates, gear 13 on the output shaft drives gear 2 14 to rotate, thereby causing drive roller shaft 1 4 to rotate. Gear 3 15 rotates with drive shaft 1, and gear 3 15 drives gear 4 16 to rotate, thereby causing driven roller shaft 1 5 to rotate. This achieves linkage between drive roller shaft 1 4 and driven roller shaft 1 5. At the same time, drive roller shaft 1 4 drives drive roller shaft 2 6 to rotate through spline 9. Gear 5 17 on drive roller shaft 2 6 rotates, and gear 5 17 drives gear 6 18 to rotate, thereby causing driven roller shaft 2 7 to rotate. This achieves linkage between drive roller shaft 2 6 and driven roller shaft 2 7.
[0042] The structure uses a motor 12 to drive four rollers to rotate synchronously, which simplifies the structure and saves space for the entire device.
[0043] like Figure 3As shown, in this embodiment, a connecting block 19 is installed on the mounting base 2, and a connecting block 20 is provided above the connecting block 19. The mounting base 2 is also provided with a driving component 21 for driving the connecting block 20 to move up and down. The active roller shaft 4 and the driven roller shaft 5 are respectively installed on the connecting block 19 and the connecting block 20. A connecting block 3 22 is installed on the mounting base 3, and a connecting block 4 23 is provided above the connecting block 3 22. The mounting base 3 is also provided with a driving component 21 for driving the connecting block 4 23 to move up and down. The active roller shaft 2 6 and the driven roller shaft 2 7 are respectively installed on the connecting block 3 22 and the connecting block 4 23.
[0044] One drive component 21 drives the connecting block 20 to move up and down, which can adjust the interval between the driven roller 5 and the driving roller 4 in the vertical direction. Another drive component 21 drives the connecting block 4 23 to move up and down, which can adjust the interval between the driven roller 7 and the driving roller 6 in the vertical direction. This structure can adjust the interval according to the thickness of the zipper head on the zipper belt, which has good adaptability. When the zipper head passes through, the drive component 21 drives the driven roller 5 and the driven roller 7 to lift up respectively, so that the zipper head can pass through smoothly and effectively avoid the zipper head being crushed.
[0045] like Figure 3 As shown, in this embodiment, the second driving component 21 includes a cylinder 24, and the second connecting block 20 and the fourth connecting block 23 are respectively installed on the piston rod of the corresponding cylinder 24.
[0046] In other embodiments, cylinder 24 can also be replaced by a hydraulic cylinder or a linear motor.
[0047] like Figure 3 As shown, in this embodiment, a connecting rod 25 is installed on one side of the connecting block 20, and a fixing block 26 is installed on one side of the connecting rod 25. The piston rod of the cylinder 24 is connected to the fixing block 26.
[0048] In this structure, connecting block 20 is mounted on the piston rod of cylinder 24 via a fixed connecting rod 25 and a fixing block 26.
[0049] like Figure 2 and 3 As shown, in this embodiment, the driving component 8, the active roller 4, the driven roller 5, the active roller 6, and the driven roller 7 constitute the zipper belt conveyor mechanism 27. There are two zipper belt conveyor mechanisms 27, which are arranged one after the other. The rotational speed of the driving component 8 on the rear zipper belt conveyor mechanism 27 is less than the rotational speed of the driving component 8 on the front zipper belt conveyor mechanism 27.
[0050] Two zipper belt conveyor mechanisms 27 are arranged side by side in the front-rear direction of the frame 1. The two conveyors together transport the zipper belt. The drive components 8 on the two zipper belt conveyor mechanisms 27 rotate at different speeds. The conveying speed of the rear zipper belt conveyor mechanism 27 is lower than that of the front zipper belt conveyor mechanism 27. This allows the front zipper belt conveyor mechanism 27 to tighten the zipper belt during the conveying process, thus achieving pre-expansion of the zipper belt.
[0051] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
