Description

Technical Field

[0001] The present invention relates to the technical field of film winding devices, and particularly to a winding device for producing non-crystalline point films. Background Art

[0002] A non-crystalline point film refers to a film material without a crystal structure and presenting an amorphous state. Different from crystalline films, non-crystalline point films do not have a regular lattice arrangement microscopically, so the arrangement of its atoms is random or disordered. This non-crystalline state endows the film with unique properties and applications in many fields of electronics, optics, and materials science.

[0003] After film production, a winding device is needed to wind and store the film. The existing winding device uses a winding wheel to wind the film. When a winding wheel finishes winding, a new winding wheel needs to be replaced. At this time, a cutting knife near the winding wheel on the winding device cuts the film, so that the wound winding wheel can make room for the new winding wheel. When replacing the new winding wheel, glue is generally applied to the new winding wheel so that the film can be wound by the new winding wheel.

[0004] However, when the existing winding device replaces a new winding wheel, the cutting knife has not yet cut the film, so that the new winding wheel will contact the film before the previous winding wheel disengages. The glue on the new winding wheel will continuously adhere to and then separate from the film, resulting in film deformation and affecting the winding quality of the film. Moreover, the cutting knife is close to the winding wheel, causing the film cut by the cutting knife to be folded when being wound by the new winding wheel, affecting the uniformity of film winding.

[0043] The following refers to Figures 1 - 13 to describe a winding device for producing a film without crystal points provided by the present invention.

[0044] A winding device for producing a film without crystal points, suitable for winding the film 300, includes a frame 100. A rotating cylinder 110 is arranged on the frame 100, and the rotating cylinder 110 can rotate around its own axis. A winding frame 200 is also arranged on the frame 100. A first winding roller 240 is rotatably arranged on the winding frame 200. The film 300 to be wound is passed through between the rotating cylinder 110 and the first winding roller 240. Glue is applied on the first winding roller 240 to adhere to the film 300 so that the film 300 can be attached to the first winding roller 240. And because the film 300 is located between the first winding roller 240 and the rotating cylinder 110 and is clamped by the first winding roller 240 and the rotating cylinder 110, the rotation of the rotating cylinder 110 can drive the first winding roller 240 to rotate through the film 300, and the first winding roller 240 winds the film 300. As more and more of the film 300 is wound on the first winding roller 240, the first winding roller 240 on the winding frame 200 needs to be replaced with a second winding roller 250 to continue winding. When replacing the second winding roller 250, an auxiliary switching frame 140 needs to be arranged on the frame 100. The auxiliary switching frame 140 is rotatably arranged on the frame 100, specifically at both ends of the rotating cylinder 110, and the auxiliary switching frame 140 can replace the second winding roller 250 onto the winding frame 200.

[0045] During the replacement process, the first winding roller 240 is about to finish winding. At this time, the second winding roller 250 is driven by the auxiliary switching frame 140 above the rotating cylinder 110 and contacts the film 300. The second winding roller 250 and the first winding roller 240 rotate synchronously. A first glue 251 and a second glue are coated on the outer circumference of the second winding roller 250. The adhesion of the first glue 251 is greater than that of the second glue 252, and the second glue 252 is located in front of the first glue 251 in the rotation direction of the second winding roller 250. When the film 300 contacts the outer circumference of the second winding roller 250, the film 300 contacts the second glue 252 and the first glue 251 on the second winding roller 250 in sequence. The second glue 252 on the second winding roller 250 contacts the film 300 first, and then the first glue 251 contacts the film 300. Since the adhesion of the first glue 251 is greater than that of the second glue 252, it is set that the second glue 252 can be separated from the second winding roller 250, while the film 300 adhered by the first glue 251 cannot be separated from the second winding roller 250. So the film 300 will first separate from the second glue 252 and the separated part is adhered with the second glue 252. Specifically, as Figure 11As shown, the second layer of glue 252 can partially adhere to the film 300, so that after the film 300 is cut, the glue attached to the cut end of the film 300 can adhere to the film 300 on the outer periphery of the first winding roller 240 to finish the winding of the film 300 on the first winding roller 240, avoiding the scattered distribution of the cut film 300 on the first winding roller 240. The first layer of glue 251 fixes the other part of the cut film 300 on the second winding roller 250, avoiding the need for operators to apply glue repeatedly.

[0046] To cut the film 300, a retractable cutting tool 220 is provided on the auxiliary switching frame 140. When the cutting tool 220 extends towards the second winding roller 250, it can cut the film 300. As Figure 10 and Figure 11 shown, the position of the cutting tool 220 after extension is just within the area between the first layer of glue 251 and the second layer of glue 252. The cutting tool 220 cuts the part of the film 300 that adheres to the second layer of glue 252 without affecting the fixation of the film 300 on the second winding roller 250 by the first layer of glue 251. An induction component is also provided on the auxiliary switching frame 140. The induction component can sense the stress state of the film 300. When the first layer of glue 251 on the outer periphery of the second winding roller 250 adheres the film 300 to the second winding roller 250 and does not come off, since the first winding roller 240 has not detached from the rotating cylinder 110, it still rotates. At this time, the film 300 will be subjected to a pulling force. The induction component is located on the auxiliary switching frame 140, between the first winding roller 240 and the second winding roller 250, and at the lower end of the film 300. When the first winding roller 240 continues to pull the film 300, the film 300 can squeeze the induction component. When the film 300 is subjected to a force exceeding the preset value, it means that the film 300 has left the area coated with the second layer of glue 252 and has reached the area of the first layer of glue 251. Since the first layer of glue 251 fixes the film 300, the film 300 is pulled. The induction component senses in time that the film 300 is pulled, so the cutting tool 220 extends in time to cut the film 300, preventing the film 300 from deforming due to excessive force.

[0047] Specifically, the induction component in the present invention includes an induction roller 170 and sliding blocks 160. There are two sliding blocks 160, and the two sliding blocks 160 are respectively slidably arranged on the auxiliary switching frame 140. The sliding blocks 160 can move radially along the rotation wheel on the auxiliary switching frame 140, while the induction roller 170 is rotatably arranged on the sliding blocks 160. The outer circumference of the induction roller 170 is in rolling contact with the film 300. When the first winding roller 240 and the second winding roller 250 rotate, the film 300 will pass through the outer circumference of the induction roller 170. Therefore, when the force condition of the film 300 changes, it will push the induction roller 170 to move radially along the rotating cylinder 110. As Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, when the first winding roller 240 rotates to pull the film 300, the film 300 pulls the second winding roller 250. Since the film 300 is adhered by the first layer of glue 251, the film 300 will apply a downward moving force to the induction roller 170 at this time, that is, the induction roller 170 moves radially along the rotating cylinder 110 towards the axis of the rotating cylinder 110. When the induction roller 170 moves a preset distance, the cutting tool 220 extends to cut the film 300. At this time, the cutting tool 220 extends towards the second winding roller 250, and the extended position is at the first layer of glue 251 of the second winding roller 250, so that when the film 300 is cut, only the part outside the first layer of glue 251 is cut, and then when the film 300 is wound onto the second winding roller 250 after being cut, there is no excess film 300 being folded, which can ensure that the second winding roller 250 can wind the film 300 more evenly later.

[0048] Meanwhile, a second layer of glue 252 is adhered to the other end of the film 300 cut by the cutting tool 220, so that this part of the film 300 can be adhered to the film 300 on the first winding roller 240 after being completely wound by the first winding roller 240, preventing the end of this part of the film 300 from floating around.

[0049] More specifically, an elastic member 162 is provided between the sliding block 160 and the auxiliary switching frame 140. The elastic member 162 in this embodiment is a spring. One end of the elastic member 162 is connected to the auxiliary switching frame 140, and the other end of the elastic member 162 is connected to the sliding block 160. The setting of the elastic member 162 enables the sensing roller 170 to reset when not subjected to a force, and enables the sensing roller 170 to have a force to resist the downward pressure of the film 300. A distance sensor (not shown in the figure) can be installed on the auxiliary switching frame 140. The distance detected by the distance sensor when the sensing roller 170 pushes the elastic member 162 to compress can reflect the force condition of the film 300, that is, the greater the compression degree of the elastic member 162, the greater the force on the film 300, and the smaller the compression degree of the elastic member 162, the smaller the force on the film 300. A preset distance is set to drive the cutting tool 220 to cut the film 300 on the premise that the film 300 does not deform. When the film 300 starts to compress the elastic member 162, it means that the first layer of glue 251 on the outer circumference of the second winding roller 250 starts to pull the film 300, and at this time the cutting tool 220 cuts the film 300, that is, the cutting time of the cutting tool 220 can be accurately obtained, and the film 300 can be accurately cut.

[0050] It should be noted that, to ensure that the sensing roller 170 can move radially along the rotating cylinder 110, a guiding frame 150 is provided on the auxiliary switching frame 140. A guiding hole is formed in the guiding frame 150, and the guiding hole extends along the radial direction of the rotating cylinder 110. A guiding rod 161 is further provided on the sliding block 160. One end of the guiding rod 161 is fixedly connected to the sliding block 160, the other end of the guiding rod 161 is inserted into the guiding hole, and the end of the guiding rod 161 located in the guiding hole is connected to the elastic member 162, so as to Figure 12 and Figure 13 As shown, there are two guiding rods 161 and guiding holes in this embodiment respectively. Therefore, when the sensing roller 170 is pressed by the force of the film 300 to squeeze the sliding block 160, the sliding block 160 can move radially along the rotating cylinder 110 through the guiding action of the guiding rod 161 and the guiding hole.

[0051] In a further embodiment, the cutting tool 220 of the present invention is telescopically arranged near the second winding roller 250, such as Figure 9 and Figure 10As shown, the cutting tool 220 is specifically located on the auxiliary switching rack 140 and is close to one end of the second winding roller 250. A telescopic cylinder 230 is provided at one end of the cutting tool 220. When the telescopic cylinder 230 expands and contracts, it can drive the cutting tool 220 to extend or shorten. When the force exerted by the film 300 on the induction roller 170 does not reach the preset value, the telescopic cylinder 230 is in a shortened state. When it is necessary to cut the film 300, the telescopic cylinder 230 quickly extends to drive the cutting edge of the cutting tool 220 to cut the film 300. After cutting, the telescopic cylinder 230 shortens and resets to prepare for the next cutting of the film 300.

[0052] In a further embodiment, to enable the winding rack 200 to drive the first winding roller 240 away from the rotating cylinder 110, the winding rack 200 is hinged to the frame 100, as Figure 1 shown. The bottom end of the winding rack 200 is hinged to the frame 100. A groove is provided at the top end of the winding rack 200, which can accommodate both ends of the first winding roller 240. A hydraulic cylinder 210 is also provided on the winding rack 200. One end of the hydraulic cylinder 210 is hinged to the frame 100, and the other end of the hydraulic cylinder 210 is hinged to the winding rack 200. When the hydraulic cylinder 210 expands or contracts, it can push the winding rack 200 to rotate around the position hinged to the frame 100, and the winding rack 200 can drive the winding roller away from the rotating cylinder 110. For example, when the hydraulic cylinder 210 is in a shortened state, the groove at the top end of the winding rack 200 is close to the rotating cylinder 110, the first winding roller 240 is located in the groove, the outer circumference of the first winding roller 240 rolls and contacts the film 300, and the film 300 also rolls and contacts the rotating cylinder 110. Therefore, when the rotating cylinder 110 rotates, it can drive the film 300 to be wound on the first winding roller 240. As more and more film 300 is wound on the first winding roller 240, the overall diameter of the first winding roller 240 gradually increases. At this time, the hydraulic cylinder 210 on the winding rack 200 gradually extends to adapt to the first winding roller 240 with a gradually increasing diameter. After the cutting tool 220 cuts the film 300, the first winding roller 240 on the winding rack 200 has finished winding, and the hydraulic cylinder 210 starts to extend, causing the winding rack 200 to drive the wound first winding roller 240 away from the rotating cylinder 110. At this time, after the winding roller is separated from the rotating cylinder 110, it stops rotating. After the operator removes the first winding roller 240, the hydraulic cylinder 210 shortens and resets to drive the winding rack 200 to reset. At this time, the auxiliary switching rack 140 drives the second winding roller 250 close to the winding rack 200, and the second winding roller 250 is repositioned on the winding rack 200 to continue winding the film 300.

[0053] Specifically, a driving component is provided on the rack 100 in this embodiment. The driving component can drive the rotating cylinder 110 to rotate and can also drive the auxiliary switching rack 140 to rotate. The driving component includes a first driving motor 120 and a second driving motor 180. The first driving motor 120 is fixedly arranged on one side of the rack 100. The rotating shaft of the first driving motor 120 is in transmission connection with the rotating shaft of the rotating cylinder 110 through a first belt 130. When the first driving motor 120 rotates, it drives the rotating cylinder 110 to rotate, specifically as Figure 4 shown.

[0054] The second driving motor 180 is fixed on the other side of the rack 100, as Figure 2 and Figure 3 shown. The rotating shaft of the second driving motor 180 is in transmission connection with the auxiliary switching rack 140. When the second driving motor 180 rotates, it can drive the auxiliary switching rack 140 to rotate around the rotating shaft.

[0055] More specifically, as Figure 3 shown, a transmission wheel 141 is coaxially and fixedly connected to the rotation center of the auxiliary switching rack 140. The rotating shaft of the second driving motor 180 is in transmission with the transmission shaft through a second belt 190. Therefore, when the second driving motor 180 rotates, the second driving motor 180 drives the auxiliary switching rack 140 to rotate, thereby driving the second winding roller 250 to move towards the winding rack 200.

[0056] It should be noted that, as Figure 3 shown, clamping jaws 142 are provided on the auxiliary switching rack 140. The clamping jaws 142 can clamp both ends of the second winding roller 250, and their function is similar to the grooves on the winding rack 200. However, the chuck 143 on the left side of the clamping jaws 142 on the auxiliary switching rack 140 is hinged to the auxiliary switching rack 140, and a torsion spring is provided at the hinge shaft so that the chuck 143 can clamp both ends of the second winding roller 250. When the auxiliary switching rack 140 rotates clockwise (the clockwise direction as viewed from front to back in Figure 3 ), both ends of the second winding roller 250 will enter the grooves of the winding rack 200. As the auxiliary switching rack 140 continues to rotate clockwise, at this time, the chuck 143 will gradually open under the abutting force of the second winding roller 250 to avoid the auxiliary switching rack 140 being unable to continue rotating clockwise due to the chuck 143 getting stuck on the second winding roller 250.

[0057] Combined with the above embodiments, the specific working process of a winding device for producing a non-crystalline point film 300 provided by the present invention is described as follows:

[0058] Start the first driving motor 120. The first driving motor 120 drives the rotating cylinder 110 to rotate through the first belt 130. At this time, the hydraulic cylinder 210 is in a shortened state. One end of the film 300 passes through the rotating cylinder 110 and the first winding roller 240 on the winding frame 200. The rotation of the rotating cylinder 110 drives the film 300 to be wound on the first winding roller 240. As the rotating cylinder 110 rotates continuously, the rotating cylinder 110 drives the film 300 to be continuously wound on the first winding roller 240, and the overall diameter of the first winding roller 240 gradually increases. The hydraulic cylinder 210 on the winding frame 200 gradually extends to adapt to the first winding roller 240 with a gradually increasing diameter. When the first winding roller 240 is about to be wound up, start the second driving motor 180. The second driving motor 180 drives the auxiliary switching frame 140 to rotate through the second belt 190. When the auxiliary switching frame 140 rotates above the rotating cylinder 110, the sensing roller 170 is located at the lower end of the film 300. Subsequently, the second winding roller 250 is installed on the clamping jaw 142 of the auxiliary switching frame 140. The outer periphery of the second winding roller 250 is coated with a first layer of glue 251 and a second layer of glue 252. The second layer of glue 252 is located in front of the first layer of glue 251 in the rotation direction of the second winding roller 250, so that the second layer of glue 252 contacts the film 300 first when the second winding roller 250 starts to rotate, and the second layer of glue 252 adheres to the film 300 first. When the first layer of glue 251 adheres to the film 300, due to the strong adhesion of the first layer of glue 251, when the first winding roller 240 rotates to pull the film 300, the film 300 has a tendency to move downward on the sensing roller 170, and the sensing roller 170 moves downward to compress the elastic member 162. When the sensing roller 170 moves to the preset position, the telescopic cylinder 230 extends, and the telescopic cylinder 230 drives the cutting tool 220 to cut the film 300. The cutting position is just between the first layer of glue 251 and the second layer of glue 252, as Figure 10 and Figure 11 shown. After the cutting tool 220 cuts the film 300, the cut end of the film 300 adheres to the second layer of glue 252. Therefore, after the first winding roller 240 is wound up, the ends of the film 300 can be adhered together, thus completing the complete winding of the first winding roller 240. Subsequently, the hydraulic cylinder 210 on the winding frame 200 extends to push the winding frame 200 to rotate, and the winding frame 200 drives the first winding roller 240 away from the rotating cylinder 110.

[0059] After the operator removes the first winding roller 240, the hydraulic cylinder 210 shortens and resets again. At this time, the second drive motor 180 drives the auxiliary switching frame 140 to rotate, thereby driving the second winding roller 250 to approach the winding frame 200. Both ends of the second winding roller 250 are located in the grooves of the winding frame 200. After the auxiliary switching frame 140 rotates one week and resets, since the first layer of glue 251 on the outer circumference of the second winding roller 250 adheres to the film 300, the rotating cylinder 110 is in rolling contact with the film 300, and the second winding roller 250 drives the other side of the film 300 to roll. The film 300 is wound on the second winding roller 250. The replacement processes of the subsequent third, fourth, and Nth winding rollers are the same as the above and will not be described in detail.

For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification.
