Description

Technical Field

[0001] The present invention relates to the technical field of waste edge winding, and specifically to a method for constant tension winding of narrow waste edges applicable to a roll cutter machine. Background Art

[0002] In the die-cutting field, narrow waste edges cut from a relatively wide material area need to be wound. The existing winding method is to directly arrange a winding roller behind the narrow waste edge. The rotation of the winding roller drives the narrow waste edge to perform a winding operation. In actual operation, the axial length of the winding roller is much larger than the width of the narrow waste edge. Therefore, when the narrow waste edge is wound around the winding roller with a fixed axial position, the narrow waste edge is likely to wind up the radial expansion space of the winding roller. Subsequently, due to the large axial space remaining in the axial direction of the winding roller, problems such as collapse and explosion of the roll are likely to occur. In addition, since the axial space in the axial direction of the winding roller cannot be utilized, the number of roll changes is frequent, resulting in low utilization rate of the winding roller. Summary of the Invention

[0003] In view of the above problems, the present invention provides a method for constant tension winding of narrow waste edges applicable to a roll cutter machine, which enables the narrow waste edges to be sequentially arranged and reciprocally wound along the axial direction of the winding roller, ensuring full utilization of the axial space of the winding roller, reducing the number of roll changes, and ensuring reliable winding.

[0004] [[ID=IMPORTANT]]A method for constant tension winding of narrow waste edges applicable to a roll cutter machine, characterized in that it comprises the following steps:

[0005] S1. Arrange a winding mechanism at the position where narrow waste edge winding is required. The winding mechanism includes a set of guiding roller groups and a winding shaft. The winding shaft is integrated with a rotating motor and an axial telescoping mechanism. The axial telescoping mechanism drives the winding shaft to reciprocally telescope along the axial direction of the winding shaft, and the rotating motor drives the winding shaft to rotate for winding;

[0006] [[ID=IMPORTANT]]S2. Then, sleuth a winding roller on the winding shaft through a key structure, so that the winding roller and the winding shaft rotate synchronously and telescoping axially;

[0007] [[ID=IMPORTANT]]S3. Pass the narrow waste edge through the guiding roller groups and then wind it around one end of the axial winding section of the winding roller. Then, drive the rotating motor and the axial telescoping motor to act, so that the narrow waste edge is sequentially arranged and reciprocally wound along the axial direction of the winding roller until the radial winding space of the narrow waste edge reaches a set threshold;

[0008] [[ID=IMPORTANT]]S4. Replace the winding roller and repeat step S3 again.

[0009] It is further characterized in that:

[0010] The guiding roller group includes two guiding rollers and a height-adjusting guiding roller. The two guiding rollers are the first guiding roller and the second guiding roller. The height-adjusting guiding roller is driven by a height-direction elastic mechanism to adaptively adjust its height in the height direction. The narrow waste edge passes through the first guiding roller, the height-adjusting guiding roller, and the second guiding roller in sequence and then winds around the axial center area of the rear winding roller.

[0011] The axial center area of the winding roller is used for winding the narrow waste edge. The axial telescopic mechanism drives the winding roller to axially expand and contract, so that the narrow waste edge winds back and forth along the axial center area.

[0012] In step S3, the overlap degree of the narrow waste edge wound in the latter time relative to the narrow waste edge wound in the adjacent previous time is at least 1 mm to ensure the reliable utilization of the corresponding axial space.

[0013] The rotating motor is a frequency conversion motor, and the rotating motor adjusts the speed in real time according to the winding thickness of the winding roller, so as to ensure that the feeding speed of the narrow waste edge is equal to the winding speed of the narrow waste edge.

[0014] The axial telescopic mechanism is an electric reciprocating telescopic mechanism, and the reciprocating movement distance of the electric reciprocating telescopic mechanism ensures that the narrow waste edge winds around the axial center area of the winding roller.

[0015] After adopting this method, the narrow waste edge passes through the guiding roller group and then winds around one end of the axial winding section of the winding roller. Then, the rotating motor and the axial telescopic motor are driven to act, so that the narrow waste edge makes a reciprocating winding movement along the axial direction of the winding roller in sequence until the winding radial space of the narrow waste edge reaches the set threshold value. This makes the narrow waste edge wind and roll back and forth in sequence along the axial direction of the receiving roller, ensuring the full utilization of the axial space of the receiving roller, reducing the number of roll changes, and ensuring the reliable winding.

[0020] A method suitable for constant-tension winding of narrow waste edges of a roller cutter machine, see Figure 1 , which includes the following steps:

[0021] S1. Arrange a winding mechanism 100 at the position where narrow waste edge winding is required. The winding mechanism 100 includes a set of guiding roller groups 10 and a winding shaft 20. The winding shaft 20 is integrated with a rotating motor and an axial telescopic mechanism. The axial telescopic mechanism drives the winding shaft 20 to reciprocate axially along the axis of the winding shaft, and the rotating motor drives the winding shaft 20 to rotate for winding.

[0022] S2. Then, sleeved a winding roller 30 on the winding shaft 20 through a key structure, so that the winding roller 30 and the winding shaft 20 rotate synchronously and axially telescopic. Specifically, in implementation, the winding shaft 20 is an air shaft. After the spline groove of the winding roller 30 is sleeved on the central shaft end of the air shaft 20, the air shaft 20 expands to complete the reliable assembly of the winding roller 30.

[0023] S3. Pass the narrow waste edge 1 through the guiding roller groups 10 and then wind it around one end of the axial winding interval of the winding roller 30. Then drive the rotating motor and the axial telescopic motor to act, so that the narrow waste edge 1 sequentially arranges reciprocating winding actions along the axial direction of the winding roller 30 until the radial winding space of the narrow waste edge 1 reaches a set threshold.

[0024] S4. Replace the winding roller 30 and repeat step S3 again.

[0025] Specifically, in implementation, the narrow waste edge includes but is not limited to PET, foam, and metal foil.

[0026] Specifically, in implementation, the guiding roller groups 10 include two guiding rollers and a height-adjusting guiding roller 13. The two guiding rollers are a first guiding roller 11 and a second guiding roller 12. The height-adjusting guiding roller 13 is driven by a height-direction elastic mechanism to adaptively adjust the height in the height direction. The narrow waste edge 1 sequentially passes through the first guiding roller 11, the height-adjusting guiding roller 13, and the second guiding roller 12 and then winds around the axial central area of the rear winding roller. The height-direction elastic mechanism presses down to ensure the tension operation of the narrow waste edge 1.

[0027] The axial central area of the winding roller 30 is used for winding the narrow waste edge 1. The axial telescopic mechanism drives the winding roller 30 to axially telescopic, so that the narrow waste edge 1 reciprocates back and forth along the axial central area for winding operation.

[0028] Specifically, in step S3, the overlap degree of the narrow waste edge wound in the latter time relative to the narrow waste edge wound in the adjacent previous time is at least 1 mm to ensure the reliable utilization of the corresponding axial space.

[0029] Specifically, in implementation, the rotating motor is a variable-frequency motor, and the rotating motor adjusts the speed in real time according to the winding thickness of the winding roller 30, so as to ensure that the feeding speed of the narrow waste edge 1 is equal to the winding speed of the narrow waste edge 1.

[0030] The axial telescopic mechanism is an electric reciprocating telescopic mechanism, and the reciprocating moving distance of the electric reciprocating telescopic mechanism ensures that the narrow waste edge is wound around the axial central area of the winding roller.

[0031] The principle is as follows: After passing through the guide roller group, the narrow waste edge is wound around one end of the axial winding section of the winding roller. Then, the rotation motor and the axial telescopic motor are driven to act, so that the narrow waste edge performs a reciprocating winding action in sequence along the axial direction of the winding roller until the radial winding space of the narrow waste edge reaches a set threshold value. This makes the narrow waste edge perform a reciprocating winding in sequence along the axial direction of the winding roller, ensuring the full utilization of the axial space of the winding roller, reducing the number of roll changes, and ensuring the reliable winding operation.
