Description

Technical Field

[0001] The utility model relates to the technical field of sheet material decoration, in particular to an automatic sheet material position calibration mechanism. Background Art

[0002] The sticker machine uses the hot pressing process to hot-press the paper on the surface of the sheet under high temperature and high pressure to achieve decoration of the sheet. In order to carry out hot pressing treatment continuously, the sheet is first conveyed to the machine by the feeding mechanism for position calibration, and then transferred to the working area padded with paper, and then the sheet with paper on both sides is transferred to the hot press for hot pressing and molding to complete the decoration.

[0003] Before placing the cardboard, the position of the sheet to be fed in needs to be calibrated to avoid surface defects of the sheet due to misalignment of the cardboard during hot pressing, such as the situation where the cardboard is not attached to a part. At present, the position calibration of the sheet is usually done by supporting it with a support structure after the sheet enters the machine, and adjusting the position by pushing the calibrator, which is a cylinder drive. After the adjustment is completed, the sheet is moved to the station with the cardboard by the transfer mechanism. This method of calibration before transfer is not only cumbersome, but also easily causes the sheet to move during transfer, which in turn causes the previous position calibration to fail, requiring recalibration or defects due to misalignment of the cardboard and sheet after hot pressing. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides an automatic sheet position calibration mechanism to solve the problem that the method of calibrating before transporting is not only cumbersome in steps, but also easily causes the sheet to move during the transport process, thereby causing the previous position calibration to fail and requiring recalibration or the paperboard and the sheet to be misaligned after hot pressing and resulting in defects.

[0005] The utility model solves the above technical problems with the following technical solutions: a mechanism for automatically calibrating the position of a sheet, comprising:

[0006] Machine;

[0007] The transfer component includes a carrier, a linear module that drives the carrier to slide in the machine, and at least two calibrators for adjusting the position of the sheet and limiting it. The linear module is arranged in the machine, the carrier is arranged on the moving end of the linear module, and at least two calibrators are respectively arranged on both sides of the carrier.

[0008] The beneficial effects of the utility model are:

[0009] 1) The device integrates a calibrator that can adjust and limit the position in the transfer component. The calibrator can directly limit the position of the sheet during the sheet transfer process. During the transfer of the sheet, the calibrator can be used to perform real-time position calibration and limit the position of the sheet, so that the calibration limit and the transfer process are carried out simultaneously without additional steps. By setting the sheet to not move during transfer, the traditional transfer method of calibrating before transfer is avoided, which leads to failure of position calibration.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the support frame is configured as two cross bars and a plurality of vertical bars fixed between the cross bars, and each of the calibrators includes a cylinder 1 and a calibration plate, wherein the cylinder 1 is fixed on the vertical bars, and the calibration plate is fixed on the driving end of the cylinder 1.

[0012] Furthermore, the linear module includes a slide rail and a pulley, the slide rail is fixed on the machine platform, and the pulley is rotatably connected to the bottom of the carrier frame through a rotating shaft and rolls on the slide rail.

[0013] The beneficial effect of adopting the above further scheme is that the calibration plate is driven to move by cylinder 1, so that the calibration plate contacts and pushes the sheet, thereby driving the sheet between the calibration plates to move left or right, and then calibrating the position of the sheet. After the position is calibrated, cylinder 1 drives the calibration plate to contact the sheet again, so that the calibration plate is held on both sides of the sheet, thereby limiting the position of the sheet and preventing the sheet on the carrier from moving when the pulley rolls and slides on the slide rail.

[0014] Furthermore, it also includes a holding component for holding the sheet when the sheet enters the machine.

[0015] Furthermore, the supporting assembly includes a supporting frame, a plurality of rollers rotatably connected to the supporting frame via a rotating shaft, and a second cylinder for driving the supporting frame to move in a direction perpendicular to the ground.

[0016] Furthermore, the top supporting frame is arranged in the machine platform, and when the supporting frame slides directly above the top supporting frame, the rollers on the top supporting frame and the vertical rods on the supporting frame are staggered and distributed, so that when the cylinder 2 drives the supporting frame to move in a direction perpendicular to the ground, the horizontal height of the rollers is higher than the vertical rods.

[0017] Furthermore, the second cylinder is arranged on the machine platform, and the driving end of the second cylinder is connected to the bottom of the top support frame.

[0018] The beneficial effect of adopting the above further scheme is that when the sheet enters the machine, as the carrier slides just above the top holding frame, the rollers on the top holding frame and the vertical bars on the carrier are staggered and distributed, and cylinder 2 drives the carrier to move in a direction perpendicular to the ground, so that the horizontal height of the rollers is higher than the vertical bars, and multiple rotatable rollers of the top holding assembly are used to ensure that the sheet slides smoothly during the process of entering the machine. When the sheet is in the machine, that is, on the rollers, as cylinder 2 drives the top holding frame to descend, the sheet falls on the vertical bars of the carrier, and then cylinder 1 drives the calibration plate to move, so that the calibration plate contacts and pushes the sheet, so as to drive the sheet located between the calibration plates to move left or right, and then calibrate the position of the sheet. After the position is calibrated, cylinder 1 drives the calibration plate to contact the sheet again, so that the calibration plate is held on both sides of the sheet to limit the position of the sheet. After the sheet is fixed and limited, the linear module is used to drive the sheet on the carrier to move toward the working area padded with cardboard.

[0019] Furthermore, a plurality of anti-slip pads are fixedly connected to the top of each vertical rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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.

[0026] The sticker machine uses the hot pressing process to hot-press the paper on the surface of the sheet under high temperature and high pressure to achieve decoration of the sheet. In order to carry out hot pressing treatment continuously, the sheet is first conveyed to the machine by the feeding mechanism, and then transferred to the working area padded with paper, and then the sheet with paper on both sides is transferred to the hot press for hot pressing and molding to complete the decoration.

[0027] Before placing the cardboard, the position of the sheet to be fed in needs to be calibrated to avoid surface defects of the sheet due to misalignment of the cardboard during hot pressing, such as the situation where the cardboard is not attached to a part. At present, the position calibration of the sheet is usually done by supporting it first through a support structure after the sheet enters the machine, and adjusting the position by pushing the calibrator, i.e., a cylinder. After the adjustment, the sheet is moved to the station padded with cardboard by the transfer mechanism. This method of calibration before transfer is not only cumbersome, but also easily causes the sheet to move during transfer, which in turn causes the previous position calibration to fail, requiring recalibration or defects due to misalignment of the cardboard and the sheet after hot pressing. In response to this, the author of the utility model proposes an automatic sheet position calibration mechanism to solve the above problems.

[0028] The utility model provides the following preferred embodiments

[0029] like Figure 1 , Figure 2 ,and Figure 3 As shown, a mechanism for automatically calibrating a sheet position comprises:

[0030] Machine 100;

[0031] The transfer assembly 200 includes a carrier 210, a linear module 220 driving the carrier 210 to slide in the machine 100, and at least two calibrators 230 for adjusting the position of the sheet and limiting it. The linear module 220 is arranged in the machine 100, the carrier 210 is arranged on the moving end of the linear module 220, and at least two calibrators 230 are respectively arranged on both sides of the carrier 210;

[0032] The device integrates a calibrator 230 capable of position adjustment and position limiting in the transfer component 200. The calibrator 230 can directly perform position limiting processing on the sheet during the sheet transfer process. During the sheet transfer process, the calibrator 230 can be used to perform real-time position calibration and position limiting on the sheet, so that the calibration and position limiting and transfer processes are carried out simultaneously without additional steps. By setting the sheet not to move during transfer, the traditional transfer method of calibrating before transfer is avoided, which leads to failure of position calibration.

[0033] In this embodiment, Figure 1 , Figure 2 ,and Figure 3As shown, the carrier 210 is provided with two cross bars 211 and a plurality of vertical bars 212 fixed between the cross bars 211, each of the calibrators 230 includes a cylinder 231 and a calibration plate 232, the cylinder 231 is fixed on the vertical bar 212, the calibration plate 232 is fixed on the driving end of the cylinder 231, the linear module 220 includes a slide rail 221 and a pulley 222, the slide rail 221 is fixed on the machine table 100, and the pulley 222 is rotatably connected to the bottom of the carrier 210 through a rotating shaft, and It rolls on the slide rail 221 and drives the calibration plate 232 to move through the cylinder 231, so that the calibration plate 232 contacts and pushes the sheet to drive the sheet between the calibration plates 232 to move left or right, and then calibrate the position of the sheet. After the position is calibrated, the cylinder 231 drives the calibration plate 232 to contact the sheet again, so that the calibration plate 232 is against both sides of the sheet to limit the position of the sheet, thereby preventing the sheet on the carrier 210 from moving when the pulley 222 rolls and slides on the slide rail 221.

[0034] In this embodiment, Figure 1 , Figure 2 ,and Figure 3 As shown in the figure, it also includes a support assembly 300 for supporting the sheet when the sheet enters the machine 100, the support assembly 300 includes a support frame 310, a plurality of rollers 320 rotatably connected to the support frame 310 through a rotating shaft, and a cylinder 330 for driving the support frame 310 to move in a direction perpendicular to the ground. The support frame 310 is arranged in the machine 100, and when the carrier frame 210 slides directly above the support frame 310, the support rollers on the support frame 310 The roller 320 and the vertical rod 212 on the carrier 210 are staggered and distributed, so that when the cylinder 2 330 drives the carrier 210 to move in a direction perpendicular to the ground, the horizontal height of the roller 320 is higher than the vertical rod 212. The cylinder 2 330 is set on the machine 100, and the driving end of the cylinder 2 330 is connected to the bottom of the top support frame 310, wherein each roller 320 is connected to the driving end of an external driving motor, so that the roller 320 can rotate;

[0035] When the sheet enters the machine 100, as the carrier 210 slides just above the top support frame 310, the rollers 320 on the top support frame 310 and the vertical rods 212 on the carrier 210 are staggered and distributed, and the cylinder 2 330 drives the carrier 210 to move in a direction perpendicular to the ground, so that the horizontal height of the rollers 320 is higher than the vertical rods 212. The top support assembly 300 uses multiple rotatable rollers 320 to ensure that the sheet slides smoothly when entering the machine 100. When the sheet is in the machine 100, that is, on the rollers 320, as the cylinder 2 330 drives the top support frame 310, the horizontal height of the rollers 320 is higher than the vertical rods 212. 0 descends, allowing the sheet to fall onto the vertical rod 212 of the carrier 210, and then the calibration plate 232 is driven to move by the cylinder 1 231, so that the calibration plate 232 contacts and pushes the sheet, so as to drive the sheet located between the calibration plates 232 to move left or right, and then calibrate the position of the sheet. After the position is calibrated, the cylinder 1 231 drives the calibration plate 232 to contact the sheet again, so that the calibration plate 232 is held on both sides of the sheet to limit the position of the sheet. After the sheet is fixed and limited, the linear module 220 is used to drive the sheet of the carrier 210 to move toward the working area padded with cardboard.

[0036] In this embodiment, Figure 1 , Figure 2 ,and Figure 3 As shown, a plurality of anti-skid pads 400 are fixedly connected to the top of each vertical rod 212. The anti-skid pads 400 can be made of rubber material or silicone. The provision of the anti-skid pads 400 helps to convert the rigid contact between the vertical rod 212 and the sheet into flexible contact, which can effectively reduce the impact force generated during the movement. At the same time, the presence of the anti-skid pads 400 can prevent scratches or damage to the surface of the sheet.

[0037] The specific working process of the utility model is as follows:

[0038] (1) Receiving sheet

[0039] First, when the sheet enters the machine 100, since the carrier frame 210 slides just above the top holding frame 310, the rollers 320 on the top holding frame 310 and the vertical rods 212 on the carrier frame 210 are staggered, and the cylinder 2 330 drives the carrier frame 210 to move in a direction perpendicular to the ground, so that the horizontal height of the rollers 320 is higher than the vertical rods 212. The top holding assembly 300 has multiple rotatable rollers 320 to ensure smooth sliding of the sheet when it enters the machine 100.

[0040] (2) Exchange support

[0041] When the sheet is in the machine 100 , that is, on the roller 320 , the cylinder 2 330 drives the top support frame 310 to descend, allowing the sheet to fall onto the vertical rod 212 of the carrier frame 210 .

[0043] The calibration plate 232 is driven to move by the cylinder 1 231, so that the calibration plate 232 contacts and pushes the sheet, so as to drive the sheet between the calibration plates 232 to move left or right, thereby calibrating the position of the sheet.

[0044] (4) Fixing the sheet

[0045] After the position is calibrated, cylinder 1 231 drives the calibration plate 232 to contact the sheet again, so that the calibration plate 232 is pressed against both sides of the sheet to limit the position of the sheet. After the sheet is fixed in position, the linear module 220 is used to drive the sheet on the carrier 210 to move toward the work station padded with cardboard.
