Description

Technical Field

[0001] This application relates to the field of roll winding equipment technology, and more particularly to a strip trimming device that can collect edge material. Background Technology

[0002] Strip materials such as films, paper, and textiles are usually first made into semi-finished rolls. In subsequent production and processing, the semi-finished rolls need to be unwound into semi-finished strips, cut into multiple finished strips of preset widths, and then rolled back into finished rolls to meet actual usage requirements.

[0003] When storing semi-finished rolls, to prevent them from rolling, workers typically stack them vertically on pallets. However, the ends of these rolls can crack under gravity and friction with adjacent rolls, resulting in varying degrees of damage along both sides of the unwound strip. Therefore, trimming is necessary during processing. However, trimming generates scrap and debris; some of this scrap and debris spreads into the environment, while some adheres to the surface of the finished strip before being wound up. The scrap and debris attached to the finished strip, under tension, can compress it, causing indentations or damage and reducing the quality of both the finished strip and the roll.

[0034] refer to Figure 1 The edge-collecting strip trimming device according to a preferred embodiment of this application will be described in detail below. The edge-collecting strip trimming device includes a main body 10, an unwinding unit 20, multiple conveyor rollers 30, a winding unit 40, a cutting unit 50, and an edge-collecting unit 60.

[0035] refer to Figure 2 The unwinding unit 20 includes a semi-finished product roll mounting mechanism 21, which is mounted on the equipment body 10. The semi-finished product roll mounting mechanism 21 forms a loading space 2101, in which the semi-finished product roll is rotatably mounted. The semi-finished product roll includes a first take-up cylinder and a semi-finished product strip, wherein the semi-finished product strip is wound around the outer peripheral wall of the first take-up cylinder.

[0036] refer to Figures 1 to 4 The winding unit 40 includes a winding mechanism 41 and a finished roll mounting mechanism 42. The winding mechanism 41 includes a winding roller 411. The finished roll mounting mechanism 42 is mounted on the equipment body 10, and the winding roller 411 is rotatably mounted on the finished roll mounting mechanism 42. The finished roll includes a second take-up cylinder and a finished strip. The semi-finished strip is cut along its two opposite sides in the width direction to obtain the finished strip. The second take-up cylinder is sleeved on the winding roller 411, and the winding roller 411 can drive the second take-up cylinder to rotate synchronously. The finished strip is wound around the outer peripheral wall of the second take-up cylinder. The axial directions of the winding roller 411, the first take-up cylinder, and the second take-up cylinder are parallel.

[0037] refer to Figures 8 to 9 The cutting unit 50 includes two spaced-apart edge cutting mechanisms 51. Both edge cutting mechanisms 51 are mounted on the main body 10 and located on the path of the unwinding of the semi-finished material strip, and are respectively opposite to the two sides of the unwound semi-finished material strip in the width direction, used to cut off the two sides of the semi-finished material strip in the width direction to obtain a finished material strip. The semi-finished material strip unwound from the semi-finished roll is cut by the edge cutting mechanism 51 to form a finished material strip, which is then wound onto the outer peripheral wall of the second take-up cylinder by the take-up roller 411, thereby obtaining a finished roll.

[0038] Each of the edge material collection units 60 includes an edge material collection pipe 61 and a negative pressure forming element 62. The edge material collection pipe 61 is installed on the equipment body 10. The edge material collection pipe 61 forms a collection port 6101, which is aligned with the position where the semi-finished material strip is cut by the edge material cutting mechanism 51. One end of the edge material collection pipe 61 away from the edge material cutting mechanism 51 is connected to a collection box. The negative pressure forming element 62 is installed on the edge material collection pipe 61 to reduce the pressure at the collection port 6101 formed by the edge material collection pipe 61, so that the edge material cut from the semi-finished material strip is collected from the collection port 6101 into the collection box under the negative pressure adsorption, thereby maintaining the cleanliness of the working environment.

[0039] In one example, the negative pressure forming element 62 is implemented as a negative pressure pump.

[0040] refer to Figure 10 and Figure 11 Preferably, the diameter of the end of the edge material collection pipe 61 that forms the collection port 6101 gradually increases in the direction toward the material belt, so that the end of the edge material collection pipe 61 that forms the collection port 6101 is funnel-shaped, thereby expanding the collection range of the collection port 6101 and improving the collection effect.

[0041] Preferably, the conveyor roller 30 is rotatably mounted on the equipment body 10, and the axial directions formed by the conveyor roller 30, the take-up roller 411, the first take-up cylinder, and the second take-up cylinder are kept parallel. Multiple conveyor rollers 30 are arbitrarily installed on the unwinding path of the semi-finished material strip and / or the winding path of the finished material strip to convey the semi-finished material strip and / or the finished material strip.

[0042] refer to Figure 1 In a preferred embodiment, some of the conveyor rollers 30 are disposed on the unwinding path of the semi-finished material strip, and the remaining portion of the conveyor rollers 30 are disposed on the winding path of the finished material strip, such that the semi-finished material strip unwound from the semi-finished roll passes sequentially around some of the conveyor rollers 30 and is then cut by the edge cutting mechanism 51 before passing sequentially around the remaining portion of the conveyor rollers 30, and the finished material strip is finally wound up by the winding roller 411.

[0043] refer to Figure 1 and Figure 2Preferably, the semi-finished roll installation mechanism 21 includes an installation component 211 and a conveyor component 212. The installation component 211 includes two spaced-apart installation bodies 2111 and an assembly 2112. The assembly 2112 is installed on the equipment body 10. Both installation bodies 2111 are slidably installed on the assembly 2112, and a loading space 2101 is formed between the two installation bodies 2111. The semi-finished roll is detachably installed between the two installation bodies 2111. Any one of the installation bodies 2111 is connected to the conveyor component 212, which drives the installation body 2111 to move along the axial direction of the first take-up cylinder towards or away from the opposite installation body 2111, thereby adjusting the size of the loading space 2101 to facilitate the installation and removal of the semi-finished roll.

[0044] In a preferred embodiment, each of the mounting components 211 includes a connector 2113, which is mounted on the mounting body 2111. The two connectors 2113 are arranged opposite to each other. The mounting bodies 2111 are located at both ends of the semi-finished roll material, and the two connectors 2113 are inserted into the first take-up cylinder through corresponding ports, so that the semi-finished roll material can be detachably inserted between the two mounting bodies 2111.

[0045] Specifically, after the old semi-finished roll is unwound, the conveyor component 212, through the mounting body 2111, moves the connector 2113 away from the opposing mounting body 2111, causing the connector 2113 to be withdrawn from the first take-up cylinder, and the old semi-finished roll is removed. After the new semi-finished roll is moved to the loading space 2101, the conveyor component 212, through the mounting body 2111, moves the connector 2113 closer to the opposing mounting body 2111, causing the connector 2113 to be inserted into the first take-up cylinder of the new semi-finished roll, thereby realizing the replacement of the semi-finished roll.

[0046] Preferably, the assembly 2112 forms a sliding guide rail 21121, and the two mounting bodies 2111 are slidably mounted on the sliding guide rail 21121. The sliding guide rail 21121 extends along an axial direction parallel to the conveyor roller 30 and is used to limit the movement of the mounting bodies 2111 along an axial direction parallel to the conveyor roller 30.

[0047] As an example, the moving member 212 is implemented as a cylinder or motor screw mechanism.

[0048] Furthermore, the unwinding unit 20 also includes a height adjustment mechanism 22, and the mounting component 2112 is rotatably mounted on the equipment body 10. The mounting component 2112 is drivably connected to the height adjustment mechanism 22, which drives the mounting component 2112 to rotate along a vertical plane, thereby causing the mounting body 2111 to rotate along a vertical plane and adjusting the height of the semi-finished coil mounting mechanism 21. The semi-finished coil mounting mechanism 21 has an unwinding position and a material changing position, wherein the unwinding position is higher than the material changing position. The height adjustment mechanism 22 drives the semi-finished coil mounting mechanism 21 to switch between the unwinding position and the material changing position.

[0049] The height adjustment mechanism 22 drives the mounting accessory 2112 to rotate, causing a portion of the loading space 2101 formed by the two mounting bodies 2111 to descend, thereby adjusting the semi-finished roll mounting mechanism 21 to the material changing position. The conveyor belt 212 drives any mounting body 2111 to move away from the opposing mounting body 2111, expanding the size of the loading space 2101 along the axial direction parallel to the take-up roller 411, so that the old semi-finished roll can be removed. Subsequently, the new semi-finished roll moves to be aligned with the axial direction of the connector 2113, and the conveyor belt 212 drives any mounting body 2111 to move closer to the opposing mounting body 2111, so that the new raw material roll is installed between the two mounting bodies 2111. After the new semi-finished roll is installed between the two mounting bodies 2111, the height adjustment mechanism 22 drives the mounting accessory 2112 to rotate in the opposite direction to adjust to the unwinding position.

[0050] Preferably, the height adjustment mechanism 22 is configured as a lockable movable cylinder or hydraulic cylinder.

[0051] Furthermore, the unwinding unit 20 also includes a first driving member 23, and the connector 2113 is rotatably mounted on the mounting body 2111. The connector 2113 is connected to the first driving member 23, and the first driving member 23 is used to drive the connector 2113 to rotate. The connector 2113 is interference-fitted with the inner wall of the first take-up cylinder, so that when the connector 2113 is driven to rotate by the first driving member 23, the connector 2113 drives the semi-finished roll to rotate in order to actively unwind the semi-finished material strip.

[0052] As an example, the first drive element 23 is implemented to include a motor.

[0053] refer to Figure 8 and Figure 9Preferably, the edge cutting mechanism 51 includes a first cutting blade 511 and a first mounting base 512. The first mounting base 512 is mounted on the equipment body 10, and the first cutting blade 511 is mounted on the first mounting base 512. The cutting edge of the first cutting blade 511 faces the side edge of the semi-finished material strip. The first cutting blade 511 cuts off the side edge so that the edge of the finished material strip wound by the winding roller 411 is neat and flat.

[0054] As an example, the first cutting blade 511 is implemented as a circular blade.

[0055] Furthermore, the edge cutting mechanism 51 includes a first pushing member 513. The first mounting base 512 is mounted on the equipment body 10, the first pushing member 513 is mounted on the first mounting base 512, and the first cutting blade 511 is connected to the first pushing member 513. The first pushing member 513 can drive the first cutting blade 511 to move radially along the winding roller 411 to adjust the distance between the cutting edge of the first cutting blade 511 and the semi-finished material strip, so that the edge cutting mechanism 51 can cut material strips of different thicknesses.

[0056] As an example, the first pusher 513 is implemented as a cylinder.

[0057] Furthermore, the cutting unit 50 also includes a spacing adjustment member 52, which is mounted on the equipment body 10. The first mounting base 512 is connected to the spacing adjustment member 52 and is used to drive the first mounting base 512 to move along an axial direction parallel to the take-up roller 411, thereby adjusting the spacing between the two edge cutting mechanisms 51 so that the two edge cutting mechanisms 51 can trim semi-finished strips of different widths.

[0058] As an example, the pitch adjustment element 52 is implemented as a magnetically coupled rodless cylinder.

[0059] refer to Figure 10 and Figure 11 Preferably, the edge material collection pipe 61 is telescopically connected to the negative pressure forming member 62, and one end of the edge material collection pipe 61 forms the collection port 6101 with the first pushing member 513, so that the collection port 6101 formed by the edge material collection pipe 61 can correspond to it as the first cutting blade 511 moves, thereby ensuring the collection effect of the edge material collection unit 60.

[0060] refer to Figure 11Furthermore, the edge material cutting mechanism 51 also includes a protective cover 514, which is connected to the first pushing member 513. The protective cover 514 forms an opening 51401 facing the semi-finished material strip. The first cutting blade 511 is rotatably mounted inside the protective cover 514, and a portion of the cutting edge of the first cutting blade 511 extends from the opening 51401 into the semi-finished material strip. Debris falls into the interior of the protective cover 514 along with the first cutting blade 511 to prevent debris from splashing. The edge material collection unit 60 also includes a branch pipe 63, the two ends of which are connected and communicate with the protective cover 514 and the edge material collection pipe 61, respectively. In this way, debris falling into the protective cover 514 is discharged from the branch pipe 63 through the edge material collection pipe 61 to the collection box under negative pressure.

[0061] It is worth mentioning that the first pushing member 513 is slidably mounted on the first mounting base 512 along an axial direction parallel to the take-up roller 411. The edge cutting mechanism 51 also includes a first locking member 514, which is threadedly mounted on the first pushing member 513, and a portion of the first mounting base 512 is located on the movement trajectory of the first locking member 514. After the first pushing member 513 slides relative to the first mounting base 512 to a predetermined position, the first locking member 514 moves closer to the first mounting base 512, causing the first locking member 514 to abut against the first mounting base 512 to fix the first pushing member 513.

[0062] It is understood that the spacing adjustment member 52 drives the edge material cutting mechanism 51 to move in a large range along the axial direction parallel to the take-up roller 411. The first cutting blade 511 can also move in a small range relative to the first mounting base 512 along the axial direction parallel to the take-up roller 411 through the first pushing member 513, so as to improve the position accuracy of the first cutting blade 511.

[0063] As an example, the first locking element 514 is implemented as a bolt.

[0064] refer to Figure 8 and Figure 12 Furthermore, the cutting unit 50 also includes at least one slitting mechanism 53, which is installed on the equipment body 10 and located between the two edge material cutting mechanisms 51. The slitting mechanism 53 is aligned with the semi-finished material strip, and the cutting direction of the slitting mechanism 53 is along the length direction of the semi-finished material strip and parallel to the cutting direction of the edge material cutting mechanism 51, so as to divide the semi-finished material strip into multiple finished material strips of a preset width.

[0065] Preferably, the slitting mechanism 53 includes a second cutting blade 531 and a second mounting base 532. The second mounting base 532 is mounted on the equipment body 10, and the second cutting blade 531 is mounted on the second mounting base 532. The cutting edge of the second cutting blade 531 faces the surface of the semi-finished material strip. The second cutting blade 531 cuts the semi-finished material strip, so that the winding roller 411 winds up the finished material strip of a preset width.

[0066] As an example, the second cutting blade 531 is implemented as a circular blade.

[0067] Furthermore, the slitting mechanism 53 includes a second pushing member 533. The second mounting base 532 is mounted on the equipment body 10, the second pushing member 533 is mounted on the second mounting base 532, and the second cutting blade 531 is connected to the second pushing member 533. The second pushing member 533 can drive the second cutting blade 531 to move radially along the winding roller 411 to adjust the distance between the cutting edge of the second cutting blade 531 and the surface of the semi-finished material strip. Thus, the slitting mechanism 53 can cut material strips of different thicknesses and select a predetermined number of the second cutting blades 531 to work according to actual needs.

[0068] As an example, the second pusher 533 is implemented as a cylinder.

[0069] Preferably, the second mounting base 532 is connected to the spacing adjustment member 52 and is used to drive the second mounting base 532 to move along an axial direction parallel to the take-up roller 411, thereby adjusting the spacing between the slitting mechanisms 53 and between the two edge cutting mechanisms 51, so that the slitting mechanism 53 can cut the semi-finished material strip into finished material strips of different widths.

[0070] Preferably, the second pushing member 533 is slidably mounted on the second mounting base 532 along an axial direction parallel to the take-up roller 411. The slitting mechanism 53 further includes a second locking member 534, which is threaded onto the second pushing member 533, and the second mounting base 532 is located on the movement trajectory of the second locking member 534. After the second pushing member 533 slides relative to the second mounting base 532 to a predetermined position, the second locking member 534 moves closer to the second mounting base 532, causing the second locking member 534 to abut against the second mounting base 532 to fix the second pushing member 533.

[0071] As an example, the second locking element 534 is implemented as a bolt.

[0072] It is understood that the spacing adjustment member 52 drives the slitting mechanism 53 to move in a large range along the axial direction parallel to the take-up roller 411, and the second cutting blade 531 can move in a small range relative to the second mounting base 532 along the axial direction parallel to the take-up roller 411 through the second pushing member 533, so as to improve the accuracy of the finished material strip width dimension.

[0073] refer to Figures 3 to 7 Furthermore, the winding mechanism 41 also includes a belt rotating mechanism 412. The belt rotating mechanism 412 is installed on the equipment body 10, and one end of the winding roller 411 is connected to the belt rotating mechanism 412. The belt rotating mechanism 412 is used to drive the winding roller 411 to rotate, so that the winding roller 411 drives the second take-up cylinder to actively wind up the finished material strip.

[0074] As an example, the drive mechanism 412 is implemented to include a motor.

[0075] Furthermore, the winding mechanism 41 also includes a bearing 413. One end of the winding roller 411 is mounted on the equipment body 10 and connected to the belt drive mechanism 412. The bearing 413 is sleeved on the end of the winding roller 411 away from the belt drive mechanism 412. The finished roll mounting mechanism 42 includes a support body 421, which is rotatably mounted on the equipment body 10 along a vertical plane. The support body 421 and the bearing 413 are positioned opposite each other, such that the winding roller 411 is supported by the support body 421 through the bearing 413.

[0076] refer to Figure 7 When the supporting body 421 is driven to rotate downwards at one end near the bearing 413, the supporting body 421 rotates away from the bearing 413 to make way for the transfer of the finished roll. At this time, the receiving roller of the roll transfer device can be inserted into the end of the take-up roller 411 where the bearing 413 is mounted. Then, when the finished roll is subjected to a force along the axial direction of the take-up roller 411 towards the receiving roller, the finished roll can move from the take-up roller 411 to the receiving roller, and then the material transfer device transfers the finished roll to a designated position. After the finished roll moves away from the take-up roller 411, the supporting body 421 rotates from bottom to top to support the take-up roller 411 together with the main body 10 of the device.

[0077] In a preferred embodiment, the support body 421 has a groove 42101 and an upward-facing opening 42102. The support body 421 rotates from bottom to top such that the bearing 413 is at least partially recessed into the groove 42101 through the opening 42102, and the inner wall of the support body 421 forming the groove 42101 restricts the bearing 413 to prevent the take-up roller 411 from moving in the horizontal direction.

[0078] refer to Figure 5 and Figure 6 Furthermore, the finished roll mounting mechanism 42 also includes an anti-shift assembly 422, which includes a stop member 4221 and a second driving member 4222. The second driving member 4222 is mounted on the support body 421, and the stop member 4221 is connected to the second driving member 4222. The second driving member 4222 is used to drive the stop member 4221 to extend into or retract from the opening 42102. When the stop member 4221 extends into the opening 42102, the opening 42102 is partially blocked, and the stop member 4221 obstructs the bearing 413, preventing the take-up roller 411 from disengaging from the opening 42102 into the groove 42101. After the second driving member 4222 drives the stop member 4221 to move away from the opening 42102, the supporting body 421 rotates from top to bottom so that one end of the take-up roller 411 that is equipped with the bearing 413 disengages from the opening 42102 from the groove 42101, so that the finished roll material can be released from the take-up roller 411.

[0079] In one embodiment, the finished roll installation mechanism 42 further includes a rotating component 423, which is installed on the equipment body 10. The supporting body 421 is connected to the rotating component 423, and the rotating component 423 is used to drive the supporting body 421 to rotate along the vertical plane.

[0080] In one example, the pivoting member 423 includes a drive cylinder 4231 and a lifting rod 4232. The drive cylinder 4231 is mounted on the device body 10, and the lifting rod 4232 is rotatably connected to the device body 10 and connected to the drive cylinder 4231. One end of the lifting rod 4232 abuts against the lower surface of the support body 421. Thus, when the drive cylinder 4231 drives the lifting rod 4232 to rotate relative to the device body 10, the end of the lifting rod 4232 near the support body 421 rises or falls, causing the support body 421 to pivot as the lifting rod 4232 moves closer to the support body 421.

[0081] refer to Figure 3Furthermore, the winding unit 40 also includes a pressing mechanism 43, which includes a pressing roller 431 and a connecting member 432. The connecting member 432 is floatingly mounted on the main body 10 of the equipment. The axial direction of the pressing roller 431 is parallel to the axial direction of the winding roller 411, and the pressing roller 431 is rotatably mounted on the connecting member 432. The pressing roller 431 remains in contact with the outermost layer of finished material strip of the finished roll that is sleeved on the winding roller 411. In this way, as the diameter of the finished roll wound by the winding roller 411 gradually increases, the position of the pressing roller 431 changes accordingly, and the outer peripheral wall of the pressing roller 431 remains in close contact with the outermost layer of finished material strip, so that the finished material strip is tightly wound around the second take-up cylinder.

[0082] In one embodiment, the connector 432 is mounted on the main body 10 of the equipment via a shaft, allowing the connector 432 to rotate along a vertical plane. The horizontal height of the pressure roller 431 is higher than that of the take-up roller 411, and thus the pressure mechanism 43, under the action of gravity, keeps the pressure roller 431 in contact with the outermost layer of finished material strip sleeved on the take-up roller 411. As the diameter of the finished material roll wound by the take-up roller 411 gradually increases, the finished material roll pushes the pressure mechanism 43 to rotate along the vertical plane away from the take-up roller 411, so as to adapt to the diameter of the finished material roll and ensure that the outer peripheral wall of the pressure roller 431 remains in contact with the outermost layer of finished material strip, so that the finished material strip is tightly wound on the second take-up cylinder.

[0083] Preferably, two sets of winding units 40 are provided, and the two sets of winding units 40 are installed vertically spaced on the main body 10 of the equipment. Two adjacent segments of finished material strip after being slit are respectively wound around a second take-up cylinder fitted with two vertically distributed winding rollers 411. It is understood that the slit finished material strip is prone to shifting during transport; therefore, adjacent finished material strips are separated vertically by the traction of the two winding rollers 411 to avoid interference during transport, ensuring the normal operation of the winding process and the quality of the wound finished material.

[0084] It is worth mentioning that the two support bodies 421 are driven by a rotating member 423, and the two support bodies 421 are connected by a linkage rod, so that when the rotating member 423 drives one of the support bodies 421 to rotate, the support body 421 drives the other support body 421 to rotate synchronously through the linkage rod, thereby reducing the number of drives and reducing the cost of the equipment.

[0085] Furthermore, the roll slitting device also includes an unloading unit 70, which includes a feeding component 71 and a driving mechanism 72. The driving mechanism 72 is mounted on the equipment body 10, and the feeding component 71 is connected to the driving mechanism 72. The driving mechanism 72 is used to drive the feeding component 71 to move axially along the take-up roller 411. When the feeding component 71 moves from the end of the take-up roller 411 away from the bearing 413 toward the end closer to the bearing 413, the finished roll material sleeved on the take-up roller 411 is pushed by the feeding component 71 to move toward the material transfer device, thereby achieving unloading.

[0086] In one embodiment, the driving mechanism 72 includes a lead screw 721 and a drive motor 722. The unloading component 71 is slidably mounted on the equipment body 10 and is threadedly connected to the lead screw 721. The drive motor 722 is mounted on the equipment body 10, and the lead screw 721 is rotatably connected to the drive motor 722. When the lead screw 721 is driven to rotate by the drive motor 722, the unloading component 71 moves axially along the take-up roller 411.

[0087] Preferably, the equipment body 10 further forms a limiting guide rail 11, which extends axially parallel to the take-up roller 411, and the unloading component 71 is slidably mounted on the limiting guide rail 11 formed by the equipment body 10. The limiting guide rail 11 is used to limit the movement of the unloading component 71 along the axial direction of the take-up roller 411.

The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
