Description

Technical Field

[0001] The present application relates to the technical field of film production, and in particular to a film waste edge cutting device and a winding coating device. Background Art

[0002] The waste edge cutting device is a device for cutting off the excess part of the film. The reason for the cutting is that different film production processes have different requirements for the width of the film. That is, if the width of the film required by the latter process is smaller than that of the former process, then before entering the latter process, the excess part of the film needs to be cut off by the waste edge cutting device, and the waste edge and the main part of the film are rolled up separately during the cutting process. However, the waste edge cutting device currently used to cut off the excess part of the film (the excess part is the waste edge to be cut out) may cause misalignment of the waste edge due to uneven force caused by left and right shaking during the process of rolling up the waste edge after cutting the waste edge. The specific manifestation of misalignment is that the end face of the waste edge is not flush and the edge of the waste edge is not in a straight line. Severe misalignment will cause the waste edge to break midway. This is because a part of the waste edge with misalignment is suspended during winding, causing the film connected to the waste edge to not be pulled tight. The waste edge cutting device cannot cut the untightened film, causing the waste edge to be disconnected from the film that has not been cut off, affecting the subsequent film cutting operation and the winding of the waste edge, and greatly reducing the cutting efficiency.

[0044] In the current waste edge cutting device of the film, after cutting and obtaining the waste edge 61, during the process of rolling up the waste edge 61, if the waste edge 61 is not pressed tightly, the waste edge 61 may shake left and right and cause misalignment. Severe misalignment will cause the waste edge 61 to break in the middle of the film, affecting the subsequent cutting operation of the film 60 and the rolling up of the waste edge 61, and greatly reducing the cutting efficiency.

[0045] In order to solve the above problems, the first embodiment of the present invention provides a film waste edge cutting device. Figure 1 to Figure 2 The film waste edge cutting device comprises a cutting component 10, a waste edge winding member 20 and a pressing mechanism. The cutting component 10 is used to cut at least one side of the film 60 in the width direction to obtain a waste edge 61. Specifically, the cutting component 10 can cut a portion with a predetermined width on one side of the film 60 along its own width direction to obtain the waste edge 61, or cut portions of a certain width on both opposite sides of the film 60 along its own width direction to obtain the waste edge 61. The waste edge winding member 20 is arranged on one side of the cutting component 10, and the waste edge winding member 20 is used to roll up the waste edge 61 cut by the cutting component 10. The pressing mechanism comprises a film passing part and a pressing assembly 31. The film passing part is arranged between the cutting component 10 and the waste edge winding member 20. The film passing part has a supporting area for supporting the waste edge 61, and the pressing assembly 31 is used to apply a pressing force to the supporting area. When the scrap edge winding member 20 winds up the scrap edge 61 cut by the cutting member 10, the scrap edge 61 first passes through the support area of ​​the film portion, and then moves from the support area to the scrap edge winding member 20 for winding up. In this process, the clamping assembly 31 of the clamping mechanism can apply a clamping force to the scrap edge 61 passing through the support area, and the scrap edge 61 being wound up will not shake under the action of the clamping force, and will not cause misalignment and end film.

[0046] It can be seen that, since the film waste edge cutting device provided in this embodiment is provided with a clamping mechanism, during the process of the waste edge winding member 20 winding up the waste edge 61 cut by the cutting member 10, a clamping force can be applied to the waste edge 61 on the supporting area passing through the film portion through the clamping assembly 31 of the clamping mechanism. Since the waste edge 61 will not shake under the action of the clamping force, the waste edge 61 in the winding will not be misaligned and cause film breakage, thereby ensuring that the cutting member 10 can continuously and effectively cut the waste edge 61 of the film 60, greatly improving the winding efficiency of the waste edge winding member 20 for winding up the waste edge 61, and the cutting efficiency of the cutting member 10 for cutting the waste edge 61.

[0047] The clamping assembly 31 includes a clamping part and a driving part. The driving part is connected to the clamping part, and the driving part is used to drive the clamping part to move toward or away from the support area. In the process of the waste edge winding unit 20 winding the waste edge 61, the driving unit drives the clamping part to approach the support area to apply a clamping force to the waste edge 61 passing through the support area to prevent the waste edge 61 from shaking and causing misalignment. After the film waste edge cutting device cuts the waste edge 61 of the film 60, the driving unit drives the waste edge 61 away from the support area.

[0048] The pressing part in this embodiment includes a connecting bracket 32 ​​and a rolling element. The connecting bracket 32 ​​is connected to the driving part. The rolling element is arranged on the connecting bracket 32 ​​and can rotate relative to the supporting area along a first direction. The first direction is as follows: Figure 1 The first direction is the direction indicated by the arrow X in the middle, that is, the direction in which the rolling element rolls accordingly with the movement of the waste edge 61. The rolling element realizes a pressing effect on the waste edge 61 during the rolling process. In this embodiment, the rolling element applies a pressing force to the waste edge 61 while being able to rotate with the movement of the waste edge 61. This can not only prevent the waste edge 61 from shaking and misaligning, but also reduce the friction between the waste edge 61 and the pressing part. Therefore, the rolling element can prevent the waste edge 61 from being crushed or stuck and difficult to move due to excessive friction, ensuring that the waste edge winding element 20 can continuously and efficiently wind up the waste edge 61.

[0049] Specifically, Figure 1 and Figure 2 As shown, the rolling element in this embodiment is a pressure wheel 33 of a wheel-shaped structure, and the first direction is the circumferential direction of the pressure wheel 33. Figure 3 As shown, the connecting bracket 32 ​​includes a connecting seat 321 and a connecting rod 322. The connecting seat 321 is provided with a mounting groove 211 on one side close to the film passing portion. The pressing wheel 33 is connected to the mounting groove 211 through the connecting rod 322. The pressing wheel 33 has a rolling surface facing the film passing portion. The pressing wheel 33 is driven by the driving unit to approach the film passing portion so that its rolling surface is pressed against the surface of the waste edge 61 passing on the supporting area of ​​the film passing portion to apply a pressing force to the waste edge 61 to prevent the waste edge 61 from shaking.

[0050] The driving part provided in this embodiment includes a mounting seat 34 and a cylinder 35. The mounting seat 34 is arranged on the side of the film passing part close to the pressing part. The cylinder 35 is arranged on the mounting seat 34, and the cylinder 35 includes a piston rod, and the piston rod is connected to the pressing part. When it is necessary to apply a pressing force to the scrap edge 61, the cylinder 35 is started, and the pressing part approaches the film passing part under the telescopic action of the piston rod of the cylinder 35 to apply a pressing force to the scrap edge 61 passing through the supporting area of ​​the film passing part. The cylinder 35 in this embodiment can also be replaced by an electric telescopic rod, and the telescopic end of the electric telescopic rod is connected to the pressing part, thereby driving the pressing part to move in the direction close to or away from the film passing part. When the pressing part is a pressing wheel 33, the pressing wheel 33 is connected to the piston rod of the cylinder 35 through the connecting bracket 32, or is connected to the telescopic end of the electric telescopic rod through the connecting bracket 32. As a result, the pressing wheel 33 can be pressed with the scrap edge 61 passing through the film part under the action of the cylinder 35 or the electric telescopic rod to prevent the scrap edge 61 from shaking.

[0051] The driving part in this embodiment also includes a control valve, which is connected to the cylinder 35 and is used to adjust the movement stroke of the piston rod along its own axial direction. The control valve is a pressure regulating valve 36. The cylinder 35 is connected to a gas source device such as a compressor and a gas cylinder through an air pipe 361. The pressure regulating valve 36 is arranged at the part of the air pipe 361 close to the cylinder. In this embodiment, the pressure regulating valve 36 adjusts the air pressure entering the cylinder 35 to adjust the length of the piston rod extending out of the cylinder 35, thereby adjusting the pressing force of the pressing part connected to the piston rod on the surface of the waste edge 61.

[0052] The film passing part in this embodiment includes a roller 30, and the part of the surface of the roller 30 that supports the scrap edge 61 is the support area. When the clamping part includes a pressing wheel 33, the axial direction of the pressing wheel 33 is parallel to the axial direction of the roller 30, so as to ensure that the rolling surface of the pressing wheel 33 can be pressed against the surface of the scrap edge 61 passing on the roller 30 under the action of the driving part. Since the supporting area for the scrap edge 61 supported by the roller 30 each time may be different, the clamping part needs to be directly opposite to the supporting area so as to be close to the supporting area under the drive of the cylinder 35 to apply a clamping force to the scrap edge 61 on the supporting area. In this regard, the clamping assembly 31 in this embodiment also includes a fixed bracket 37 and a slide rail 38. The slide rail 38 is arranged on the fixed bracket 37, and the length of the slide rail 38 extends along the axial direction of the roller 30. The driving part is connected to the slide rail 38 and can move relative to the slide rail 38 along the length direction of the slide rail 38. In this embodiment, the positional relationship between the pressing part connected to the driving part and the film passing part is adjusted according to actual conditions by moving the driving part along the length direction of the slide rail 38, so as to ensure that the pressing part can face the supporting area on the film passing part that actually supports the scrap edge 61. When the scrap edge 61 passes through the corresponding supporting area, the driving part drives the pressing part to approach the supporting area to apply a pressing force to the scrap edge 61.

[0053] The clamping assembly 31 also includes a limiter, which is arranged on the driving part, and the limiter is used to limit the driving part to a predetermined position on the slide rail 38. After pushing the driving part to move relative to the slide rail 38, thereby adjusting the relative position between the pressure wheel 33 on the driving part and the roller 30, the driving part is fixed on the slide rail 38 to prevent the driving part from deviating from the current position and affecting the pressure of the pressure wheel 33 on the waste edge 61. Specifically, the limiter in this embodiment can be a fastener such as a limit bolt 39 or a screw. When the driving part is a mounting seat 34 and a cylinder 35 arranged on the mounting seat 34, the limit bolt 39 is pre-installed on the mounting seat 34 to prevent it from falling, and it can also be conveniently used at any time during use. The mounting seat 34 is connected to the slide rail 38 and can move relative to the slide rail 38, thereby driving the pressure wheel 33 connected to the cylinder 35 to move along the length direction of the roller 30 until the pressure wheel 33 is arranged relative to the support area on the roller 30 that actually supports the waste edge 61. Specifically, as Figure 2As shown, a buckling groove 341 is provided on one side of the mounting seat 34 close to the slide rail 38. The slide rail 38 includes a track body 381 and a buckling flange 382. The track body 381 is fixedly connected to the fixing bracket 37. The length of the track body 381 extends along the axial direction of the roller 30. The buckling flange 382 is adapted to the buckling groove 341. The buckling flange 382 is provided on one side of the track body 381 close to the buckling groove 341 and buckled in the buckling groove 341. That is, the mounting seat 34 is buckled on the buckling flange 382 through the buckling groove 341 and can move relative to the track body 381 along the length direction of the track body 381. Correspondingly, a plurality of threaded holes compatible with the limiting bolts 39 can be set on the slide rail 38 along its own length direction. After pushing the mounting seat 34 to push the clamping part to a position corresponding to the support area where the waste edge 61 on the roller 30 is located, the limiting bolts 39 are screwed into the corresponding threaded holes to achieve a fixed connection between the mounting seat 34 and the slide rail 38.

[0054] The scrap edge winding member 20 in this embodiment can be a common winding roller 54, but the scrap edge winding member 20 in this embodiment is preferably an inflatable shaft. An inflatable shaft is a shaft whose surface can protrude after being inflated with high pressure, and whose surface part can be quickly retracted after being deflated. The scrap edge 61 is rolled up on the inflatable shaft during inflation. After the rolling is completed, the inflatable shaft is deflated, and the surface of the inflatable shaft is quickly retracted and separated from the scrap edge 61 coil, so that the rolled scrap edge 61 can be conveniently and quickly removed from the inflatable shaft.

[0055] In addition, the cutting component 10 in this embodiment includes a waste edge cutting roller 11 and a cutting tool, and the cutting tool is arranged on the waste edge cutting roller 11 to cut off the waste edge 61 on the film 60. The film 60 is unrolled onto the waste edge cutting roller 11, and the waste edge 61 cut by the cutting tool on the waste edge cutting roller 11 first passes through the roller 30, and the pressure wheel 33 driven by the cylinder 35 applies a pressing force to the waste edge 61 on the roller 30 to ensure that the waste edge 61 will not be misaligned due to shaking during the process of the air shaft rolling up the waste edge 61. The main body 62 of the film after the waste edge 61 is cut off can be rolled up by the pre-set winding roller 54, or directly unrolled to the next processing step, which greatly improves the production efficiency of the film 60. For example, before the film 60 is acid-plated, the waste edge 61 on the film 60 as the excess part of the film 60 needs to be cut off, otherwise the acid cannot be carried out. In this embodiment, after the waste edge 61 on the film 60 is cut off by the cutting tool on the waste edge cutting roller 11, the film body 62 can be directly unwound to the acidification process for acidification treatment.

[0056] The film waste edge cutting device provided in this embodiment is usually also called a slitting and rewinding machine. Figure 1As shown, the film waste edge cutting device also includes an unwinding air shaft 40, a heating roller 41, a flattening roller 42, a transfer roller 43 and a vacuum adsorption roller 44. In this embodiment, before the film 60 is unwound onto the waste edge cutting roller 11 for the waste edge cutting operation, the film 60 starts to unwind from the unwinding air shaft 40 and then passes through the heating roller 41 for ironing to improve some slight deformations on the film surface of the film 60. The ironed film 60 is flattened by the flattening roller 42, and then passes through two transfer rollers 43 and a vacuum adsorption roller 44. The function of the vacuum adsorption roller 44 is to cut off the tension of the film 60 and increase the friction. The film 60 coming out of the vacuum adsorption roller 44 passes through another flattening roller 42 and a transfer roller 43 and then reaches the waste edge cutting roller of the film waste edge cutting device. The waste edge 61 and the film body 62 separated from the waste edge 61 are obtained by cutting the excess part of the film 60 by the waste edge cutting roller 11. The scrap edge 61 passes through the roller 30 opposite to the pressing wheel 33, and the pressing wheel 33 rolls the scrap edge 61 on the roller 30 under the action of the cylinder 35 to prevent the scrap edge 61 from shaking and causing misalignment. The rolled scrap edge 61 reaches the air shaft for winding.

[0057] The second embodiment of the present invention provides a roll-to-roll coating device, which includes a vacuum coating chamber 50, and a film waste edge cutting device is arranged in the vacuum coating chamber 50. The structure of the film waste edge cutting device is specifically referred to the content provided in the first embodiment of the present invention, and this embodiment will not be repeated here.

[0058] For example, if the film 60 needs to be coated with a corresponding metal film layer using a roll coating device before acid coating, the film waste edge cutting device can be installed in the corresponding roll coating device before acid coating. For example, when the roll coating device includes a magnetron sputtering device or an evaporation coating device, the film waste edge cutting device can be installed in the vacuum coating chamber 50 of the magnetron sputtering device. Alternatively, the film waste edge cutting device is installed in the vacuum coating chamber 50 of the evaporation coating device. In this embodiment, the film waste edge cutting device is placed in the vacuum coating chamber 50 of the corresponding type of roll coating device, so as to perform the waste edge cutting operation 61 on the coated film 60 in the vacuum coating chamber 50, thereby avoiding the film 60 oxidation problem caused by cutting the waste edge 61 outside the vacuum coating chamber 50.

[0059] Specifically, Figure 4As shown, when the film waste edge cutting device is installed in the vacuum coating chamber 50 of the magnetron sputtering device, the vacuum coating chamber 50 of the magnetron sputtering device is also provided with an unwinding roller 51, a cooling main roller 52, a target material 53, a transmission roller 43 and a winding roller 54. The target material 53 is arranged around the cooling main roller 52. When the film 60 is unwound from the unwinding roller 51 to the cooling main roller 52, the target material 53 is sputtered onto the film 60 to coat the corresponding film layer. The coated film 60 passes through one or more transmission rollers 43 to reach the waste edge cutting roller 11 of the film waste edge cutting device. The waste edge cutting roller 11 cuts the excess part of the film 60 to obtain the waste edge 61 and the film body 62 separated from the waste edge 61. The scrap edge 61 passes through the roller 30 opposite to the pressing wheel 33. The pressing wheel 33 rolls the scrap edge 61 on the roller 30 under the action of the cylinder 35 to prevent the scrap edge 61 from shaking and causing misalignment. The rolled scrap edge 61 reaches the air shaft for winding. The film body 62 reaches the winding roller 54 to complete winding.

[0060] When the film waste edge cutting device is installed in the vacuum coating chamber 50 of the evaporation coating equipment, Figure 5 As shown, the vacuum coating chamber 50 of the evaporation coating equipment is also provided with an unwinding roller 51, a cooling main roller 52, an evaporation source 55 and a winding roller 54. The evaporation source 55 is provided on the side of the cooling main roller 52 that needs to support the film 60, and the coating particles evaporated by the evaporation source 55 are deposited on the film 60 passing through the cooling main roller 52 to achieve coating. The plated film 60 passes through one or more transmission rollers 43 to reach the waste edge cutting roller 11 of the film waste edge cutting device, and the waste edge cutting roller 11 cuts the excess part of the film 60 to obtain the waste edge 61 and the film body 62 separated from the waste edge 61. The waste edge 61 passes through the roller 30 arranged opposite to the pressure wheel 33, and the pressure wheel 33 rolls the waste edge 61 on the roller 30 under the action of the cylinder 35 to prevent the waste edge 61 from shaking and causing misalignment. The rolled waste edge 61 reaches the air shaft to achieve winding. The film body 62 reaches the winding roller 54 to complete winding.

[0061] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0062] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
