Description

Technical Field

[0001] The present application relates to the technical field of die-cutting machines, and in particular to a die-cutting machine and production process for producing optical films. Background Art

[0002] As the application scope of optical films gradually expands, the technology of more and more optical film production and processing equipment is also constantly improving. When die-cutting optical films, a die-cutting machine is needed to complete the die-cutting of the optical films.

[0003] In the prior art, after the optical film is cut, the waste generated is mainly peeled off by gravity-assisted blowing. That is, after the film is cut, the waste is blown by a blowing device, so that the waste falls under the action of its own gravity and airflow to peel off the optical film. The optical film after cutting can be output to the outside.

[0004] However, the separation method between this type of optical film and waste material requires extremely high sharpness of the film cutting tool. During actual film cutting, the film cutting between the waste material and the optical film is not thorough, and the waste material and the optical film are not completely separated. In addition, after the film cutting tool has performed multiple film cutting operations, when waste material debris adheres to the film cutting tool, it will have an adverse effect on the film cutting effect of the film cutting tool to a certain extent. The waste material after film cutting is difficult to remove from the optical film, and it needs to be further peeled off manually. The overall production efficiency is low, so further improvement is needed. Summary of the Invention

[0005] In order to improve the separation effect between optical films and waste materials, the present application provides a die-cutting machine and production process for producing optical films.

[0006] In the first aspect, the present application provides a die-cutting machine for producing optical films, which adopts the following technical solutions: A die-cutting machine for producing optical films, comprising a film cutting machine body, a material receiving assembly and a material shaking assembly, the film cutting machine body having a film cutting channel, the material receiving assembly and the material shaking assembly both being arranged at the outlet end of the film cutting channel for removing waste materials; a mounting frame is provided on one side of the film cutting machine body, the material shaking assembly comprises a conveying roller, a conveying elastic belt and a material shaking piece, the conveying roller is rotatably mounted on the mounting frame, and a plurality of conveying rollers are arranged at intervals along the film conveying direction, the conveying elastic belts are wound around the outer peripheral sides of a plurality of conveying rollers; the material shaking piece is provided on the mounting frame for forcing the conveying elastic belt to shake.

[0007] By adopting the above-mentioned technical solution, after the optical film is cut by the film cutting machine body, it is discharged outward through the film cutting channel. The material receiving assembly can reel in the waste material (scraps) from the film cutting, separating the optical film from this waste material. In addition, when the optical film is transported to the conveyor elastic belt of the mounting frame, the conveyor elastic belt is forced to shake by the shaking element to shake off the waste material (such as debris or scraps remaining on the optical film). The combination of the material receiving assembly and the shaking assembly greatly improves the separation between the optical film and the waste material, thereby improving overall production efficiency.

[0008] Optionally, the conveying elastic belt is ring-shaped and forms an installation area, and the material shaking part includes a rotating rod, a support rod and a rotating motor. The rotating rod is arranged in the installation area, and the support rod is connected to the rotating rod, and two are symmetrically arranged around the central axis of the rotating rod. The distance between the two support rods is greater than the outer diameter of the conveying roller; the rotating motor is arranged on the installation frame, and the output shaft of the rotating motor is coaxially connected to the rotating rod.

[0009] By adopting the above-mentioned technical solution, the distance between the two struts is greater than the outer diameter of the conveyor roller. As the output shaft of the rotating motor continues to rotate at a high speed, the two struts can intermittently beat the conveyor elastic belt, forcing the conveyor elastic belt to "jump" to cause the optical film on the conveyor elastic belt to shake, thereby improving the separation effect between the optical film and the waste.

[0010] Optionally, the film cutting machine body is provided with a connecting frame, and the receiving assembly includes a receiving roller, a guide roller and a driving motor. The receiving roller is rotatably mounted on the connecting frame, and the guide roller is rotatably mounted on the side wall of the film cutting machine body. The waste material bypasses the guide roller and is wound around the outer peripheral wall of the receiving roller; the driving motor is arranged on the connecting frame, and the output shaft of the driving motor is connected to the receiving roller.

[0011] By adopting the above technical solution, the receiving roller is driven to rotate by the driving motor so that the waste material can be rolled up.

[0012] Optionally, the connecting frame is rotatably installed with a first rotating shaft, and the output shaft of the driving motor is coaxially connected to the first rotating shaft; a rotating frame is provided at one end of the receiving roller, and two docking blocks are provided on the rotating frame, and the two docking blocks are symmetrically distributed around the central axis of the receiving roller; the receiving roller and the first rotating shaft are eccentrically arranged, and a pushing block for pushing the docking block is provided at one end of the first rotating shaft; when the first rotating shaft rotates, the pushing block alternately pushes the two docking blocks to force the rotating frame to rotate intermittently.

[0013] By adopting the above technical solution, the two docking blocks are symmetrically arranged around the central axis of the take-up roller, and are eccentrically positioned between the take-up roller and the first rotating shaft. This allows the push blocks to alternately push the two docking blocks as the first rotating shaft rotates, achieving intermittent rotation of the turret (i.e., the take-up roller intermittently reels the waste material). This intermittent reeling of the waste material balances the take-up roller's speed and the optical film's conveying speed. Furthermore, the intermittent rotation of the take-up roller creates a speed change when the roller transitions from a stationary state to a rotating state, achieving a "sudden pull" on the waste material and improving the separation efficiency between the waste material and the optical film.

[0014] Optionally, the connecting frame is hinged with a swing frame, and the swing frame is connected to a traction roller, and the waste material passes around the guide roller and the traction roller in sequence and is wound around the outer peripheral wall of the receiving roller; the connecting frame is provided with a swing member for driving the swing frame to swing.

[0015] By adopting the above-mentioned technical solution and setting up the traction roller, when the receiving roller receives the material, the traction roller is first driven to swing by the swing frame, so that the traction roller lifts and pulls the waste material of the optical film, thereby peeling the waste material from the optical film in advance and improving the stability of the waste material winding.

[0016] Optionally, the first rotating shaft is connected to an eccentric column, which is eccentrically arranged between the eccentric column and the first rotating shaft; the swinging member includes a sliding frame, a connecting rod and a control bar, the sliding frame is slidably installed on the side wall of the connecting frame, one end of the connecting rod is hinged to the sliding frame, and the other end is hinged to the eccentric column of the first rotating shaft; the sliding frame is provided with a pushing groove, one end of the control bar is connected to the swinging frame, and the other end is passed through the pushing groove; when the first rotating shaft swings, the sliding frame forces the swinging frame to swing back and forth through the control bar.

[0017] By adopting the above-mentioned technical solution, when the first rotating shaft rotates, it drives the eccentric column to "revolve" around the central axis of the first rotating shaft, thereby driving the sliding frame to slide back and forth through the connecting rod. The sliding frame can drive the swing frame to swing back and forth through the control bar, thereby achieving early traction of the waste and improving the operational convenience of the overall structure.

[0018] Optionally, the connecting frame has a first point position and a second point position. When the swing frame drives the traction roller to swing from the first point position toward the second point position, the traction roller pulls the waste material, and the receiving roller stops rotating; when the swing frame drives the traction roller to swing from the second point position toward the first point position, the traction roller releases the waste material, and the receiving roller rotates to receive the material.

[0019] By adopting the above technical solution, as the traction roller swings from the first position toward the second position, it pulls the waste material while the take-up roller is stopped, allowing the waste optical film to be peeled off in advance. After the traction roller completes pulling the waste material, it swings from the second position toward the first position, during which the take-up roller rotates and releases the waste material, allowing the take-up roller to reel it in, thereby improving the stability of the overall structure.

[0020] Optionally, the swing frame includes a second rotating shaft and a connecting bar, the second rotating shaft is rotatably mounted on the connecting frame body, one end of the connecting bar is connected to the traction roller, and the other end is hinged to the second rotating shaft; the connecting frame body is provided with a vibrating member, and when the traction roller swings from the first point position to the second point position, the vibrating member forces the traction roller to vibrate.

[0021] By adopting the above technical solution, when the traction roller swings from the first point to the second point (that is, when the traction roller pulls the waste), the vibrating member forces the traction roller to vibrate with a certain amplitude, thereby improving the stripping effect of the waste.

[0022] Optionally, a reset spring is provided between the connecting bar and the second rotating shaft, and the vibrating member includes a first magnet and a second magnet, the first magnet is arranged on the side wall of the connecting frame, and the second magnet is arranged on the side wall of the connecting bar, and when the traction roller swings to the first point position, the first magnet and the second magnet are magnetically attracted to each other.

[0023] By adopting the above technical solution, when the traction roller is located at the first point position, the first magnet and the second magnet are magnetically attracted to each other; when it is necessary to force the traction roller to swing from the first point position to the second point position, the second rotating shaft is driven to rotate. As the second rotating shaft continues to rotate, the elastic force of the reset spring gradually becomes greater than the magnetic force between the first magnet and the second magnet, and the first magnet and the second magnet are separated from each other, thereby forcing the traction roller to swing from the first point position to the second point position. Under the action of the reset spring, the traction roller can vibrate, thereby improving the waste stripping effect.

[0024] In a second aspect, the present application provides a production process for an optical film using the following technical solutions: A production process for an optical film specifically includes the following steps: S1, loading: feeding the optical film into the film cutting channel of the film cutting machine body; S2, film cutting: cutting the optical film; S3, removing: removing waste after film cutting.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the arrangement of the receiving assembly and the shaking assembly, after the optical film is cut by the film cutting machine body, it is output outward through the film cutting channel. The receiving assembly can reel in the waste material (scraps) from the film cutting, separating the optical film from this waste material. In addition, when the optical film is transported to the conveyor elastic belt of the mounting frame, the shaking element forces the conveyor elastic belt to shake off the waste material on the optical film (such as debris or scraps remaining on the optical film). The combination of the receiving assembly and the shaking assembly greatly improves the separation between the optical film and the waste material, thereby improving overall production efficiency. 2. Through the arrangement of the docking block and the pushing block, the two docking blocks are symmetrically distributed around the central axis of the take-up roller, and the take-up roller is eccentrically arranged with respect to the first rotating shaft. When the first rotating shaft rotates, the pushing blocks can alternately push the two docking blocks, thereby achieving intermittent rotation of the rotating frame (i.e., the take-up roller intermittently reels the waste material). By intermittently reeling in the waste material, on the one hand, the take-up speed of the take-up roller and the conveying speed of the optical film can be balanced. On the other hand, the intermittent rotation of the take-up roller, when the take-up roller changes from a stopped state to a rotating state, forms a speed change, achieving the purpose of "suddenly pulling" the waste material, thereby improving the peeling effect between the waste material and the optical film to a certain extent; 3. Through the setting of the vibrating member, when the traction roller is located at the first position, the first magnet and the second magnet are magnetically attracted to each other; when it is necessary to force the traction roller to swing from the first position to the second position, the second rotating shaft is driven to rotate. As the second rotating shaft continues to rotate, the elastic force of the reset spring gradually becomes greater than the magnetic force between the first magnet and the second magnet, and the first magnet and the second magnet separate from each other, thereby forcing the traction roller to swing from the first position to the second position. Under the action of the reset spring, the traction roller can vibrate, thereby improving the stripping effect of the waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following combination Figures 1-11 This application is described in further detail. Example 1

[0029] The embodiment of the present application discloses a die-cutting machine for producing optical films.

[0030] Reference Figure 1 A die-cutting machine for producing optical films includes a film cutting machine body 1, a material receiving assembly 2 and a material shaking assembly 3. The film cutting machine body 1 has a film cutting channel 11, and the optical film is cut in the film cutting channel 11; a material discharge roller 16 is rotatably installed on one side of the film cutting machine body 1, and the optical film is wound around the outer peripheral wall of the material discharge roller 16; the material receiving assembly 2 and the material shaking assembly 3 are both arranged at the outlet end of the film cutting channel 11 (that is, the material receiving assembly 2 and the material shaking assembly 3 are both arranged on the side of the film cutting machine body 1 away from the material discharge roller 16) to remove waste generated by film cutting.

[0031] A connecting frame 12 is mounted on the side of the film cutting machine body 1 away from the discharge roller 16. The receiving assembly 2 includes a receiving roller 21, a guide roller 22, and a drive motor 23. The ends of the receiving roller 21 are rotatably mounted on the side wall of the connecting frame 12, while the ends of the guide roller 22 are rotatably mounted on the side wall of the film cutting machine body 1 away from the discharge roller 16. In this embodiment, there are two guide rollers 22. The drive motor 23 is fixedly mounted on the side wall of the connecting frame 12. In this embodiment, the output shaft of the drive motor 23 is coaxially connected to one end of the receiving roller 21.

[0032] Reference Figure 1 、 Figure 2 The side wall of the connecting frame 12 is provided with a swing frame 14, which is connected to a pulling roller 15. The swing frame 14 includes a second rotating shaft 141 and a connecting bar 142. The two ends of the second rotating shaft 141 are rotatably mounted on the connecting frame 12. In this embodiment, one end of the connecting bar 142 is fixedly connected to the swing frame 14, and the other end is fixedly connected to the pulling roller 15. Two connecting bars 142 are provided and symmetrically distributed at both ends of the pulling roller 15. After the waste passes through the two guide rollers 22 and the pulling roller 15 in sequence, it is wound around the outer peripheral wall of the receiving roller 21.

[0033] The connecting frame 12 is provided with a swinging member 5 for driving the swinging frame 14 to swing. In this embodiment, the swinging member 5 is configured as a cylinder 54, the cylinder body of the cylinder 54 is hinged to the side wall of the film cutting machine body 1, and the piston rod of the cylinder 54 is hinged to the second rotating shaft 141. When the piston rod of the cylinder 54 extends outward, it drives the second rotating shaft 141 to rotate around its own central axis and forces the traction roller 15 to swing toward the side close to the film cutting machine body 1; when the piston rod of the cylinder 54 contracts inward, the traction roller 15 swings toward the side away from the film cutting machine body 1.

[0034] It should be noted that when the traction roller 15 swings toward the side close to the film cutting machine body 1, the traction roller 15 pulls the waste material, and when the traction roller 15 swings toward the side away from the film cutting machine body, the traction roller 15 loosens the waste material.

[0035] Reference Figure 1 、 Figure 3 The film cutting machine body 1 is mounted on a side away from the unwinding roller 16. The shaking assembly 3 includes a conveyor roller 31, a conveyor elastic belt 32, and a shaking element. The conveyor roller 31 is rotatably mounted on the mounting frame 4 and is spaced apart along the film conveying direction. In this embodiment, the conveyor rollers 31 can be driven by a motor (not shown). The conveyor elastic belt 32 is wound around the outer periphery of the conveyor rollers 31. Multiple conveyor elastic belts 32 are spaced apart along the axial direction of the conveyor rollers 31. These multiple conveyor elastic belts 32 are used to transport the cut optical film.

[0036] Reference Figure 3 、 Figure 4 The shaking member is arranged on the mounting frame 4 to force the conveying elastic belt 32 to shake vertically. The conveying elastic belt 32 is annular and forms a mounting area 321. The shaking member includes a rotating rod 33, a support rod 34 and a rotating motor. The two ends of the rotating rod 33 are rotatably mounted on the side walls of the mounting frame 4 and are located in the mounting area 321. The outer peripheral wall of the rotating rod 33 is fixedly mounted with a spring frame 331, and the support rod 34 is fixedly connected to the spring frame 331 of the rotating rod 33. In this embodiment, there are two support rods 34, and the two support rods 34 are symmetrically distributed around the central axis of the rotating rod 33. The distance between the two support rods 34 is greater than the outer diameter of the conveying roller 31.

[0037] The rotating motor (not shown) is fixedly mounted on the side wall of the mounting frame 4 , and the output shaft of the rotating motor passes through the side wall of the mounting frame 4 and is coaxially connected to the rotating rod 33 .

[0038] The implementation principle of Example 1 of the present application is as follows: after the optical film is cut by the film cutting machine body 1, it is output outward from the film cutting channel 11, and the waste material of the film cutting is passed around the guide roller 22 and the traction roller 15 in turn and wound around the outer peripheral wall of the receiving roller 21. As the film cutting proceeds, the receiving roller 21 is driven to rotate, and the waste material (scraps) of the film cutting can be wound up, so that the optical film can be separated from this part of the waste material.

[0039] Furthermore, when the optical film is transported to the elastic conveyor belt 32 of the mounting frame 4, the rotating rod 33 is driven to rotate, and the support rod 34 forces the elastic conveyor belt 32 to vibrate, thereby shaking off waste materials (such as debris or residual scraps of the optical film) on the optical film. The combination of the receiving assembly 2 and the shaking assembly 3 greatly improves the separation of optical film and waste materials, thereby increasing overall production efficiency. Example 2

[0040] The embodiment of the present application discloses a die-cutting machine for producing optical films.

[0041] The difference between the die-cutting machine for producing optical films disclosed in the embodiment of the present application and the embodiment 1 is that: Reference Figure 5 、 Figure 6 、 Figure 7In this embodiment, the connecting frame 12 is rotatably mounted with a first rotating shaft 13, and the output shaft of the driving motor 23 is coaxially connected to the first rotating shaft 13; a rotating frame 211 is fixedly mounted at one end of the receiving roller 21, and two docking blocks 212 are mounted on the rotating frame 211, and the two docking blocks 212 are symmetrically distributed around the central axis of the receiving roller 21; the receiving roller 21 and the first rotating shaft 13 are eccentrically arranged, and a pushing block 131 for pushing the docking block 212 is fixedly mounted at one end of the first rotating shaft 13; when the first rotating shaft 13 rotates, the first rotating shaft 13 drives the pushing block 131 to alternately push the two docking blocks 212, so as to force the rotating frame 211 to rotate intermittently.

[0042] It should be noted that, in this embodiment, a ratchet and pawl structure can be provided at the rotation point of the receiving roller 21 and the connecting frame 12 (the ratchet can be installed on the outer peripheral wall of the receiving roller 21, and the pawl can be installed on the side wall of the connecting frame 12. The ratchet and pawl structure is a prior art and its structure will not be elaborated on here, and it is not shown in the figure) to limit the unidirectional rotation of the receiving roller 21, forcing the receiving roller 21 to only be able to "receive materials" but not to "discharge materials".

[0043] Reference Figure 8 、 Figure 9 、 Figure 10 An eccentric column 132 is fixedly connected to the first rotating shaft 13, and the eccentric column 132 is eccentrically arranged with respect to the first rotating shaft 13; in this embodiment, the swinging member 5 includes a sliding frame 51, a connecting rod 52 and a control bar 53. A sliding groove 123 is provided on the side wall of the connecting frame body 12, and the sliding frame 51 is slidably installed in the sliding groove 123; one end of the connecting rod 52 is hinged to the sliding frame 51, and the other end is hinged to the eccentric column 132 of the first rotating shaft 13; a pushing groove 511 is provided on the side wall of the sliding frame 51, one end of the control bar 53 is fixedly connected to the swinging frame 14, and the other end is passed through the pushing groove 511; when the eccentric column 132 "revolves" around the central axis of the first rotating shaft 13, the sliding frame 51 forces the swinging frame 14 to swing back and forth through the control bar 53.

[0044] The connecting frame 12 has a first position 121 and a second position 122. When the swing frame 14 drives the pulling roller 15 to swing from the first position 121 toward the second position 122 (i.e., when the pulling roller 15 swings toward the side closer to the film cutting machine body 1), the pulling roller 15 pulls the waste material, and the receiving roller 21 stops rotating. When the swing frame 14 drives the pulling roller 15 to swing from the second position 122 toward the first position 121 (i.e., when the pulling roller 15 swings toward the side away from the film cutting machine body 1), the pulling roller 15 releases the waste material, and the receiving roller 21 rotates to collect the material.

[0045] The operating principle of Example 2 of the present application is as follows: the two docking blocks 212 are symmetrically arranged around the central axis of the take-up roller 21, and the take-up roller 21 is eccentrically positioned relative to the first rotating shaft 13. This allows the pusher blocks 131 to alternately push the two docking blocks 212 when the first rotating shaft 13 rotates, achieving intermittent rotation of the rotating frame 211 (i.e., the take-up roller 21 intermittently reels the waste material). This intermittent reeling of the waste material balances the take-up speed of the take-up roller 21 and the conveying speed of the optical film. Furthermore, the intermittent rotation of the take-up roller 21 creates a speed change when the take-up roller 21 transitions from a stopped state to a rotating state, achieving a "sudden pull" of the waste material and, to a certain extent, improving the peeling effect between the waste material and the optical film.

[0046] As the traction roller 15 swings from the first position 121 toward the second position 122, it pulls the waste material, while the take-up roller 21 is stopped, allowing for early removal of the waste optical film. After the traction roller 15 completes its pulling of the waste material, it swings from the second position 122 toward the first position 121. During this process, the take-up roller 21 rotates and the traction roller 15 releases the waste material, allowing the take-up roller 21 to reel it in, improving the stability of the overall structure. Example 3

[0047] The embodiment of the present application discloses a die-cutting machine for producing optical films.

[0048] The difference between the die-cutting machine for producing optical films disclosed in the embodiment of the present application and embodiment 2 is that: Reference Figure 11 In this embodiment, one end of the connecting bar 142 is fixedly connected to the traction roller 15, and the other end is hinged to the second rotating shaft 141. A reset spring is installed between the connecting bar 142 and the second rotating shaft 141. The reset spring can be a torsion spring (not shown in the figure). One end of the torsion spring is fixedly connected to the side wall of the connecting bar 142, and the other end is fixedly connected to the second rotating shaft 141.

[0049] The connecting frame 12 is provided with a vibrating member 6. When the pulling roller 15 swings from the first point 121 toward the second point 122 (i.e., when the pulling roller 15 swings toward the side closer to the film cutting machine body 1), the vibrating member 6 forces the pulling roller 15 to vibrate. The vibrating member 6 includes a first magnet 61 and a second magnet 62. The first magnet 61 is fixedly mounted on the side wall of the connecting frame 12, and the second magnet 62 is fixedly mounted on the side wall of the connecting bar 142. When the pulling roller 15 swings to the first point 121, the first magnet 61 and the second magnet 62 are magnetically attracted to each other.

[0050] The implementation principle of Example 3 of the present application is as follows: when the traction roller 15 swings to the first point position 121, the first magnet 61 and the second magnet 62 are magnetically attracted to each other; when it is necessary to force the traction roller 15 to swing from the first point position 121 toward the second point position 122, the second rotating shaft 141 is driven to rotate. As the second rotating shaft 141 continues to rotate, the elastic force of the reset spring gradually becomes greater than the magnetic force between the first magnet 61 and the second magnet 62, and the first magnet 61 and the second magnet 62 are separated from each other, thereby forcing the traction roller 15 to swing from the first point position 121 toward the second point position 122. Under the action of the reset spring, the traction roller 15 can form vibration, thereby improving the waste stripping effect. Example 4
