Description

Technical Field

[0001] This invention relates to the technical field of die-cutting processing, specifically to a fast-moving positioning retainer. Background Technology

[0002] For membrane products, die-cutting is generally used for processing. When die-cutting membrane products, a roller cutter is used. The roller cutter uses its protruding blade to process membrane products of a certain width. In actual use, the width range of membrane products varies relatively greatly, and the membrane products entering the roller cutter area need to have a consistent width to ensure product consistency. Therefore, retaining rings are installed in front of the roller cutter to restrict the width direction of the membrane product. The retaining rings are fixed to the corresponding axial position of the roller shaft by EVA foam, and the width direction of the membrane product is fixed by the spacing between two sets of retaining rings. Because the retaining ring needs to be fixed in place via EVA foam, adjusting its position is relatively complex. When the width or position of the film product changes, it is necessary to first release the retaining ring from the EVA foam, then move the EVA foam, and then fix the retaining ring in place via the EVA foam and the roller. The device needs to measure the distance between the two sets of retaining rings using measuring tools to ensure that the material width between the two sets of retaining rings meets the position and size requirements of the roller cutter's feed width. However, the existing method of adjusting the retaining ring distance is inefficient, and there is an urgent need to develop a retaining ring structure that can move quickly. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a quick-moving positioning retainer fixture, which can quickly adjust the axial position of the retainer and ensure accurate and reliable spacing between the two sets of retainers.

[0004] A fast-moving positioning clasp fixture, characterized in that it comprises: The mounting bracket includes two connecting brackets on both sides and a connecting shaft; The sleeve roller has at least one set of recessed grooves along its length on its outer surface. Each set of recessed grooves includes at least one row of horizontally spaced recessed grooves, and each recessed groove is a ball-shaped groove. Two sets of retaining rings, each set of retaining rings includes a sleeve ring located at the radial center, and radially protruding connecting rings are respectively provided on both sides of the sleeve ring in the width direction. Each set of connecting rings is provided with a plurality of radially penetrating positioning holes, which penetrate to the inner wall of the sleeve ring. And several ball-head positioning mechanisms, including ball heads and radial adjustment mechanisms; Each radial through-hole is provided with an internal threaded hole. The radial adjustment mechanism includes an adjusting stud. The radial inner end of the adjusting stud is directly or indirectly connected to a ball head. The adjusting stud is threaded to the radial through-hole, and the ball head is protruding from the inner wall of the sleeve ring. In the assembled state, the sleeve roller is fixedly sleeved on the connecting shaft, and the sleeve rings of the two sets of retaining rings are respectively sleeved on the corresponding axial positions of the sleeve roller. Each sleeve ring is provided with a ball head positioning mechanism at the position of the concave hole groove group corresponding to the circumferential position. The radial adjustment mechanism drives the ball head to be inserted into the concave hole groove at the corresponding position. The outer circumference of the roller is marked with graduation lines along its length.

[0005] Its further features are: The inner radial end of the adjusting stud is directly connected to a ball head. At this time, the outer radial end of the adjusting stud is provided with a recessed countersunk drive groove. By inserting the drive head into the recessed countersunk drive groove, the ball head can be embedded in or disengaged from the recessed groove, thereby completing the adjustment of the distance between the two sets of retaining rings. The inner radial end of the adjusting stud is indirectly connected to the ball head. At this time, the radial adjustment mechanism also includes a linear spring. The linear spring is pressed into the inner radial end of the adjusting stud. The inner end of the linear spring is pressed into the guide limiting end of the ball head. The ball head protrudes outward from the radial through positioning hole. By pre-compressing the linear spring with the adjusting stud, the linear spring generates pressure on the guide limiting end of the ball head. When the ball head receives the reverse pressure of the concave groove, the ball head retracts. Then, the operator directly drives the retaining ring to move along the axial direction of the roller until it reaches the appropriate axial position. Then, the ball head is aligned and pressed into the concave groove by the elastic force of the linear spring. This makes the axial position adjustment of the two sets of retaining rings convenient and quick. The radial inner end of the radial through positioning hole is provided with a stop end corresponding to the guide limiting end, and the stop end ensures that the ball head will not come off. The outer surface of the sleeve roller has two sets of concave holes along the length direction. The two sets of concave holes are set at both ends of the same diameter along the length direction, which makes each set of retaining rings connected to two sets of symmetrically arranged ball head positioning mechanisms, ensuring that the retaining rings will not be axially offset due to misoperation. Each set of recessed slots includes several recessed slots arranged horizontally in two rows. The two rows of recessed slots in the same set are arranged adjacent to each other and are staggered at equal intervals. The arrangement of two rows of recessed holes ensures that the minimum spacing between the recessed holes used for positioning is 1mm, thus ensuring the good versatility of the entire fixture. After the sleeve roller is fitted onto the connecting shaft, the two ends of the sleeve roller along its length are axially positioned by wing nuts and clamping studs. When only a small axial offset of the two sets of retaining rings is required, the axial offset of the two sets of retaining rings can be achieved by the axial offset of the sleeve roller line relative to the connecting shaft, which makes the offset adjustment of the retaining rings more diverse. Each set of side connecting frames includes a fixed base and a support rod. The outer end of the fixed base is fixed to the corresponding installation position on the die-cutting production line. The inner end of the fixed base is fixed to one end of the support rod, and the other end of the support rod is fixed to the corresponding end of the connecting shaft, which makes the installation of the entire side connecting frame quick and convenient.

[0006] After adopting the above technical solution, by driving the radial adjustment mechanism, the ball head is disengaged from the corresponding concave groove, and then the retaining ring is driven to move axially to the corresponding axial position. Then, the radial adjustment mechanism is driven again, so that the two sets of ball heads of each set of retaining rings are inserted and positioned in the concave groove. By setting the outer convex end of the ball head to conform to the concave groove, the ball head is completely embedded in the concave groove. Since ball head positioning is set on both sides of the width direction of each set of retaining rings, the positioning of the retaining rings is stable and reliable. Combined with the scale line set on the outer circumference of the sleeve roller along the length direction, the gap can be obtained by the difference. It can quickly adjust the axial position of the retaining ring and ensure that the gap between the two sets of retaining rings is accurate and reliable. Attached Figure Description

Detailed Implementation

[0008] A fast-moving positioning clasp fixture, see Figures 1-6It includes a mounting frame 10, a sleeve roller 20, two sets of retaining rings 30, and several ball head positioning mechanisms 40; Mounting bracket 10 includes two connecting brackets 50 on both sides and a connecting shaft 60; The outer surface of the sleeve roller 20 is provided with at least one set of recessed groove groups 70 along the length direction. Each set of recessed groove groups 70 includes at least one row of several recessed grooves 71 arranged horizontally at intervals. Each recessed groove 71 is a ball-shaped recessed groove. Each set of retaining rings 30 includes a sleeve ring 31 located at the radial center. The sleeve ring 31 has radially protruding connecting rings 32 on both sides in the width direction. Each set of connecting rings 32 has four radially penetrating positioning holes 33 arranged at equal intervals, and the radially penetrating positioning holes 33 penetrate to the inner wall of the sleeve ring 31. Each ball head positioning mechanism 40 includes a ball head 80 and a radial adjustment mechanism 90; Each radial through-positioning hole 33 is provided with an internal threaded hole. The radial adjustment mechanism 90 includes an adjusting stud 91. The radial inner end of the adjusting stud 91 is directly or indirectly connected to a ball head 80. The adjusting stud 91 is threaded to the radial through-positioning hole 33, and the ball head 80 is provided to protrude from the inner wall of the sleeve ring 31. In the assembled state, the sleeve roller 20 is fixedly sleeved on the connecting shaft 60, and the sleeve rings 31 of the two sets of retaining rings 30 are respectively sleeved on the corresponding axial positions of the sleeve roller 20. Each sleeve ring 31 is provided with a ball head positioning mechanism 40 at the position of the concave hole groove group 70 in the circumferential position. The radial adjustment mechanism 90 drives the ball head 80 to be inserted into the concave hole groove 71 at the corresponding position. The outer circumference of the roller 20 is marked with scale lines along the length direction (not shown in the figure; these can be printed or engraved according to the actual scale).

[0009] Specific embodiment 1: The inner radial end of the adjusting stud 91 is directly connected to the ball head 80. At this time, the outer radial end of the adjusting stud 91 is provided with an internal hexagon countersunk drive groove 911. By inserting the drive head into the internal hexagon countersunk drive groove 911, the ball head 80 can be embedded in or disengaged from the concave hole groove 71, thereby completing the adjustment of the distance between the two sets of retaining rings 30.

[0010] Specific embodiment 2: The radial inner end of the adjusting stud 91 is indirectly connected to the ball head 80. At this time, the radial adjustment mechanism 90 also includes a linear spring 92. The linear spring 92 is pressed into the radial inner end of the adjusting stud 91. The inner end of the linear spring 92 is pressed into the guide limiting end 81 of the ball head 80. The ball head 80 protrudes outward from the radial through positioning hole 33. By adjusting the stud 91 to pre-compress the linear spring 92, the linear spring 92 generates pressure on the guide limiting end 81 of the ball head 80. When the ball head 80 receives the reverse pressure of the concave groove 71, the ball head 80 retracts. Then, the operator directly drives the retaining ring 30 to move axially along the sleeve roller 20 until it reaches the appropriate axial position. Then, the ball head 80 is adjusted to be aligned, so that the ball head is pressed into the concave groove 71 by the elastic force of the linear spring 92. This makes the axial position adjustment of the two sets of retaining rings 30 convenient and quick. The radial inner end of the radial through positioning hole 33 is provided with a stop end 34 corresponding to the guide limiting end, and the stop end 34 ensures that the ball head 80 will not come off.

[0011] In specific implementation, the outer surface of the sleeve roller 20 has two sets of concave hole grooves 70 along the length direction. The two sets of concave hole grooves 70 are set at both ends of the same diameter along the length direction, so that each set of connecting rings 32 of each set of retaining rings 30 is connected to two sets of symmetrically arranged ball head positioning mechanisms 40, ensuring that the retaining rings 30 will not be axially offset due to misoperation. Each set of recessed slots 70 includes two rows of horizontally spaced recessed slots 71. The two rows of recessed slots 71 in the same set of recessed slots 70 are arranged adjacent to each other, and the two rows of recessed slots 71 are arranged alternately at equal intervals. The arrangement of two rows of recessed holes 71 ensures that the minimum spacing between the recessed holes 71 used for positioning is 1mm, thus ensuring good versatility of the entire fixture.

[0012] In practice, after the sleeve roller 20 is fitted onto the connecting shaft 60, the two ends of the sleeve roller 20 along its length are axially installed and positioned by the wing nuts 21 and the clamping studs 22. When only a small axial offset of the two sets of retaining rings 30 is required, the axial offset of the two sets of retaining rings 30 can be achieved by the axial offset of the sleeve roller 20 relative to the connecting shaft 60, which makes the offset adjustment of the retaining rings 30 more diverse.

[0013] In practice, each side connecting frame 50 includes a fixed base 51 and a support rod 52. The outer end of the fixed base 51 is fixed to the corresponding installation position on the die-cutting production line, and the inner end of the fixed base 51 is fixed to one end of the support rod 52. The other end of the support rod 52 is fixed to the corresponding end of the connecting shaft 60, which makes the installation of the entire side connecting frame 50 quick and convenient.

[0014] Its working principle is as follows: By driving the radial adjustment mechanism, the ball head disengages from the corresponding concave groove, and then drives the retaining ring to move axially to the corresponding axial position. Then, the radial adjustment mechanism is driven again, so that the two sets of ball heads of each set of retaining rings are inserted and positioned in the concave groove. By setting the outer convex end of the ball head to conform to the concave groove, the ball head is completely embedded in the concave groove. Since ball head positioning is set on both sides of the width direction of each set of retaining rings, the positioning of the retaining rings is stable and reliable. Combined with the scale lines set along the length direction on the outer circumference of the sleeve roller, the gap can be obtained by the difference. It can quickly adjust the axial position of the retaining ring and ensure that the gap between the two sets of retaining rings is accurate and reliable.
