Description

Technical Field

[0001] The utility model relates to the technical field of sheet winding, in particular to a fast winding device in a sheet laminating machine. Background Art

[0002] The sheet material commonly used in laminating machines is laminating film material, which is a thin film used to cover and protect the surface of flat materials.

[0003] At present, there are some problems in the sheet cutting process. First, if the tension of the sheet is too large, the sheet will be tight, which may cause the cut sheet to bounce and cause damage. Second, the rolled sheet may scatter after cutting, requiring the operator to rewind it, which increases the complexity of the operation. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a fast winding device in a sheet laminating machine to solve the problem that if the tension of the sheet is too large, the sheet will be tight, which may cause the cut sheet to fly and cause damage; secondly, the rolled sheet may scatter after cutting, requiring the operator to re-roll it, which increases the complexity of the operation.

[0005] The utility model solves the above technical problems with the following technical solutions: a fast winding device in a sheet laminating machine includes a sheet used by the laminating machine, and also includes:

[0006] A bracket;

[0007] A support assembly, which is disposed on the top of the bracket and holds up the moving sheet;

[0008] A winding assembly, the winding assembly is arranged at the bottom of the support, the winding assembly includes a sleeve, a fixed seat, and a driving member driving the sleeve to rotate, the fixed seat is fixed on the support, the sleeve is rotatably connected to the fixed seat through a rotating shaft, and the sleeve is fixed on the driving end of the driving member. When the driving member drives the sleeve to rotate, the sleeve is wound and rolled up the moving sheet held by the support assembly;

[0009] A tension adjustment component, which is disposed between the winding component and the supporting component and is used to adjust the tension of the moving sheet;

[0010] A cutting assembly, which is arranged on one side of the winding assembly and is used to cut and break the sheet material wound on the winding assembly;

[0011] The sheet material laminating assembly is arranged on one side of the sleeve and is used for laminating the sheet material rolled up on the outer layer of the sleeve onto the sleeve.

[0012] The beneficial effects of the utility model are:

[0013] 1) The device uses a tension adjustment component to reduce the tension of the sheet to avoid the phenomenon of sheet tension caused by excessive tension. After the sleeve has finished winding the sheet, after the cutting component accurately cuts the sheet outside the sleeve, the sheet bonding component is used to firmly bond the cut sheet to the sleeve. This design can effectively prevent the tough sheet from being stretched due to excessive tension and flying after cutting, which not only causes damage to the cutting area of ​​the sheet, but also requires the operator to rewind the broken and flying sheet on the sleeve onto the sleeve, increasing the complexity of the operation. The device can improve the safety, automation and efficiency of the cutting process, thereby improving production efficiency and product quality.

[0014] On the basis of the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, the support assembly includes a first roller and a second roller, and the first roller and the second roller are rotatably connected to the bracket via a rotating shaft respectively.

[0016] The beneficial effect of adopting the above further solution is that the sheet is attached to the upper side of roller one and roller two, and is wound from the right side of roller two to the left side of the tension roller and is wrapped around the circumferential outer side of the sleeve.

[0017] Furthermore, the tension adjustment assembly includes a crossbeam, a slot, a slider, a cylinder 1, a slide rod and a tension roller, the crossbeam is fixed on the bracket, the slot is opened inside the crossbeam, the slider slides on one side of the crossbeam, one end of the slide rod of the slider penetrates the slot and is fixed on the slider, one end of the tension roller is rotatably connected to the slide rod via a rotating shaft, the cylinder 1 is fixed on the crossbeam, and the driving end of the cylinder 1 is connected to one side of the slide rod, when the cylinder 1 is driven along the axis of the driving end, the slide rod is driven to slide and displace on the crossbeam along the length of the crossbeam.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that when cylinder 1 drives the slider to move along the axis of the driving end, it drives the slider to slide on the beam along the length of the beam, and the slider is fixedly connected to the slide rod, so the slide rod and the tension roller will also move accordingly. In the process of sliding displacement of the tension roller, the degree of bending of the sheet between roller 2 and the sleeve is driven, thereby changing the tension of the tension roller on the sheet. In this way, the tension of the sheet can be effectively adjusted so that it is not too tight, thereby reducing the flying phenomenon that occurs during the cutting process.

[0019] Furthermore, the cutting component is configured as a laser cutting machine.

[0020] Furthermore, the sheet laminating assembly includes a vertical plate, a turntable, an arm, a laminating roller, a gear, a rack, and a second cylinder.

[0021] Furthermore, the vertical plate is fixed on the bracket, the turntable is rotatably connected to the side of the vertical plate close to the sleeve through a rotating shaft, the gear is rotatably connected to the side of the vertical plate away from the sleeve through a rotating shaft, the gear is fixedly connected to the turntable, the rack is located on one side of the gear and meshes with the gear, the cylinder is fixed on the vertical plate, and the driving end of the cylinder is connected to one side of the rack, the arm is fixed on the turntable, and the laminating roller is rotatably connected to the arm through a rotating shaft.

[0022] Furthermore, the turntable and the sleeve are coaxially arranged.

[0023] Furthermore, the length of the arm is greater than the diameter of the sheet after being rolled up by the sleeve.

[0024] The beneficial effect of adopting the above further scheme is that when cylinder 2 drives the rack to move, the gear rotates counterclockwise, thereby driving the turntable to rotate counterclockwise. Since the turntable and the sleeve are coaxially arranged, and the length of the arm is greater than the diameter of the sleeve after the sheet is wound up, the arm will rotate counterclockwise along the outer edge of the sleeve. In this way, the laminating roller will rotate counterclockwise along the sheet on the outer edge of the sleeve, and the sheet that falls freely after being cut will be accurately laminated to the outer edge of the sleeve.

DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The sheet material commonly used in laminating machines is laminating film material, which is a thin film used to cover and protect the surface of flat materials.

[0032] At present, there are some problems in the sheet cutting process. First, if the tension of the sheet is too large, the sheet will be tight, which may cause the cut sheet to fly and cause damage. Secondly, the rolled sheet may scatter after cutting, requiring the operator to re-roll it, which increases the complexity of the operation. In this regard, the utility model proposes the above-mentioned problem of a fast winding device in a sheet laminating machine.

[0033] The utility model provides the following preferred embodiments

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the fast winding device in the sheet material 100 laminating machine includes the sheet material 100 used by the laminating machine, and also includes:

[0035] A bracket 200;

[0036] A support assembly 300, which is disposed on the top of the bracket 200 and holds up the moving sheet 100;

[0037] The winding assembly 700 is arranged at the bottom of the bracket 200. The winding assembly 700 includes a sleeve 701, a fixed seat 702, and a driving member 703 for driving the sleeve 701 to rotate. The fixed seat 702 is fixed on the bracket 200. The sleeve 701 is rotatably connected to the fixed seat 702 through a rotating shaft. The sleeve 701 is fixed on the driving end of the driving member 703 (driven by a driving motor, and the output end of the driving motor and the sleeve 701 are transmitted through a chain sprocket). When the driving member 703 drives the sleeve 701 to rotate, the sleeve 701 is wound and rolled up the moving sheet 100 held by the support assembly 300.

[0038] A tension adjustment component, wherein the tension adjustment component 400 is disposed between the winding component 700 and the supporting component 300 and is used to adjust the tension of the moving sheet 100;

[0039] A cutting assembly 500, which is disposed on one side of the winding assembly 700 and is used to cut and break the sheet 100 wound on the winding assembly 700;

[0040] The sheet laminating assembly 600 is arranged on one side of the sleeve 701 and is used to laminar the sheet 100 rolled up on the outer layer of the sleeve 701 onto the sleeve 701. The tension of the sheet 100 is reduced by the tension adjusting assembly to avoid the sheet 100 being stretched due to excessive tension. After the sleeve 701 has rolled up the sheet 100, after the cutting assembly 500 has accurately cut off the sheet 100 outside the sleeve 701, the sheet laminating assembly 600 is used to cut the cut sheet 100. The sheet 100 is firmly attached to the sleeve 701. This design can effectively prevent the tough sheet 100 from being too tight due to excessive tension and flying away after being cut. This not only causes damage to the cut area of ​​the sheet 100, but also requires the operator to rewind the broken and flying sheet 100 on the sleeve 701 onto the sleeve 701, increasing the complexity of the operation. The device can improve the safety, automation and efficiency of the cutting process, thereby improving production efficiency and product quality.

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the support assembly 300 includes a roller 1 301 and a roller 2 302, and the roller 1 301 and the roller 2 302 are respectively connected to the bracket 200 by a rotating shaft, and the sheet 100 is attached to the upper side of the roller 1 301 and the roller 2 302, and is wound from the right side of the roller 2 302 to the left side of the tension roller 406 and is wound on the circumferential outer side of the sleeve 701. The tension adjustment assembly 400 includes a crossbeam 401, a slot 402, a slider 403, a cylinder 1 404, a slide bar 405 and a tension roller 406. The crossbeam 401 is fixed to the bracket 2 00, the slot 402 is formed inside the beam 401, the slider 403 slides on one side of the beam 401, one end of the slide rod 405 of the slider 403 penetrates the slot 402 and is fixed on the slider 403, one end of the tension roller 406 is rotatably connected to the slide rod 405 through a rotating shaft, the cylinder 1 404 is fixed on the beam 401, and the driving end of the cylinder 1 404 is connected to one side of the slider 403, when the cylinder 1 404 is driven along the axis of the driving end, the slider 403 is driven to slide and displace on the beam 401 along the length of the beam 401.

[0042] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the cutting assembly 500 is configured as a laser cutting machine.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the sheet laminating assembly 600 includes a vertical plate 601, a turntable 602, an arm 603, a laminating roller 604, a gear 605, a rack 606, and a cylinder 607. The vertical plate 601 is fixed on the bracket 200. The turntable 602 is rotatably connected to the side of the vertical plate 601 close to the sleeve 701 through a rotating shaft. The gear 605 is rotatably connected to the side of the vertical plate 601 away from the sleeve 701 through a rotating shaft. The gear 605 is fixedly connected to the turntable 602. The rack 606 is located on one side of the gear 605 and meshes with the gear 605. The cylinder is fixed on the vertical plate 601, and the driving end of the cylinder is connected to one side of the rack 606. The arm 603 is fixed on the turntable 602. The closing roller 604 is rotatably connected to the arm 603 via a rotating shaft. The turntable 602 is coaxially arranged with the sleeve 701. The length of the arm 603 is greater than the diameter of the sheet 100 after being rolled up by the sleeve 701. When the cylinder 2 607 drives the rack 606 to move, the gear 605 rotates counterclockwise, thereby driving the turntable 602 to rotate in a counterclockwise direction. Since the turntable 602 is coaxially arranged with the sleeve 701, and the length of the arm 603 is greater than the diameter of the sheet 100 after being rolled up by the sleeve 701, the arm 603 will rotate counterclockwise along the outer edge of the sleeve 701. In this way, the bonding roller 604 will rotate counterclockwise along the sheet 100 on the outer edge of the sleeve 701, and the sheet 100 that falls freely after being cut will be accurately bonded to the outer edge of the sleeve 701.

[0044] The specific working process of the utility model is as follows:

[0045] (1) Reduce the tension of the sheet during the winding process

[0046] First, the cylinder 1 404 is used to drive the slider 403 to move along the axis of the driving end, so as to drive the slider 403 to slide on the beam 401 along the length of the beam 401, and the slider 403 is fixedly connected to the slide bar 405, so the slide bar 405 and the tension roller 406 will also move accordingly. During the sliding displacement of the tension roller 406, the bending degree of the sheet 100 between the roller 2 302 and the sleeve 701 is driven, thereby changing the tension of the tension roller 406 on the sheet 100. In this way, the tension of the sheet 100 can be effectively adjusted so that it is not too tight, thereby reducing the flying phenomenon during the cutting process.

[0047] (2) Cutting the sheet 100 between the outer edge of the sleeve 701 and the tension roller 406

[0048] A laser cutting machine is used to emit a laser beam to the sheet 100 , and a high-energy-density laser beam is used to heat-process the sheet 100 , thereby cutting the sheet 100 .

[0049] (3) Rewinding the broken sheet 100

[0050] When cylinder 2 607 drives rack 606 to move, gear 605 rotates counterclockwise, thereby driving turntable 602 to rotate counterclockwise. Since turntable 602 is coaxially arranged with sleeve 701, and the length of arm 603 is greater than the diameter of sleeve 701 after winding sheet 100, arm 603 will rotate counterclockwise along the outer edge of sleeve 701. In this way, laminating roller 604 will rotate counterclockwise along sheet 100 on the outer edge of sleeve 701, and accurately laminating sheet 100 that falls freely after being cut onto the outer edge of sleeve 701.
