Description

Technical Field

[0001] The invention relates to a continuous pressing device and process for preparing a composite film in the technical field of composite film preparation. Background Art

[0002] Composite film is an adhesive formed by mixing polymers, organic solvents and various additives, and then the adhesive is sandwiched and packaged with two films to form a multi-layer composite structure similar to a sandwich. The existing packaging device for preparing composite film usually applies adhesive on one side of the film, and then presses the other film and the adhesive together with a roller. The composite film can be prepared after curing treatment. However, the thickness of the existing films for preparing composite films varies due to different specifications. In order to ensure the flatness of the surfaces of different films before bonding, different tensions need to be applied to them according to the thickness of the films. However, the existing composite film packaging device cannot automatically adjust its tension according to the thickness of the film.

[0022] like Figure 1 and Figure 3-Figure 5As shown, the transmission mechanism 2 includes a first motor 201, which is fixedly connected to the left side of the mounting frame 11, and the output shaft of the first motor 201 is fixedly connected to the active roller 14 on the lower side, and the two active rollers 14 are driven by a gear set.

[0024] like Figure 1 and Figure 6-Figure 9As shown, the tension control assembly 4 includes a first fixed cylinder 401, the first fixed cylinder 401 is fixedly connected to the support block 302 on the right side of the front square frame 301, a first piston rod 402 is slidably connected in the first fixed cylinder 401, the first piston rod 402 is fixedly connected to the support block 302 on the left side of the front square frame 301, the two support blocks 302 in the front square frame 301 are separated from each other so that the first piston rod 402 extends out from the corresponding first fixed cylinder 401, and the left side of the first fixed cylinder 401 is connected to the first guide Liquid tube 403, a second fixed cylinder 404 is fixedly connected to the left side of the sliding plate 17, the second fixed cylinder 404 is connected to the first liquid guide tube 403, the second fixed cylinder 404 is sealed and slidably connected with a second piston rod 405, the second piston rod 405 is fixedly connected to the push plate 113, the left side of the first fixed cylinder 401, the first liquid guide tube 403 and the right side of the second fixed cylinder 404 are all filled with hydraulic oil, and the second piston rod 405 controls the moving distance of the push plate 113 through the flow of hydraulic oil in the first liquid guide tube 403.

[0025] like Figure 1 and Figure 6-Figure 9 As shown, the clamping control assembly 5 includes a third fixed cylinder 501, the third fixed cylinder 501 is fixedly connected to the support block 302 on the right side of the rear square frame 301, the third fixed cylinder 501 is sealingly and slidably connected to the third piston rod 502, the third piston rod 502 is fixedly connected to the support block 302 on the left side of the rear square frame 301, the two support blocks 302 in the rear square frame 301 are separated so that the third piston rod 502 extends out from the corresponding third fixed cylinder 501, the left side of the third fixed cylinder 501 is connected to the second liquid guide tube 503, the mounting frame 11 is fixedly connected to the fourth fixed cylinder 504, the fourth fixed cylinder 504 is connected to the second The liquid guide tube 503 is connected, and the fourth fixed cylinder 504 is sealed and slidably connected with the fourth piston rod 505. The fourth piston rod 505 is squeezed and matched with the corresponding sliding block 114. The fourth piston rod 505 moves downward under the action of hydraulic oil and squeezes and pushes the corresponding sliding block 114 to move downward. The left side of the third fixed cylinder 501 and the second liquid guide tube 503 are filled with hydraulic oil. Through the movement of the two clamping rollers 303, the fourth piston rod 505 pushes the corresponding sliding block 114 downward, thereby achieving the purpose of controlling the clamping force of the two clamping rollers 115 on the two films when they are bonded, thereby ensuring the tightness of the two films during processing.

[0026] When the operator uses the device to prepare the packaging of the composite film, the operator first places the film to be coated with glue on the loading device 12, places a roller with the film rolled up at the discharge roller 16, pulls the film out from the discharge roller 16 through the two clamping rollers 303 and the two rotating rollers 15, and the two support blocks 302 in the corresponding square frame 301 of the two clamping rollers 303 are away from each other.

[0027] When the film is inserted between the two rotating rollers 15, the operator starts the second motor 202 through the control panel, and the second motor 202 drives the rotating roller 15 on the right to rotate counterclockwise (from front to back), and the two rotating rollers 15 on the upper side rotate synchronously in opposite directions through the gear set, and the two rotating rollers 15 transport the film passing through the two clamping rollers 303 downward, and the film moves to the right around the supporting roller 111 and the two guide rollers 19, and the guide roller 19 drives the sliding plate 17 to move upward through the corresponding supporting frame 18, and the sliding plate 17 compresses the spring connected to it, and the sliding plate 17 maintains the pressing force on the film on the lower side under the elastic force of the spring connected thereto, and then the two films pass through the two pressing rollers 115 and the two pairs of one-way wheels 204, and are finally placed in the composite film winding device on the right side of the device. At this time, the film between the rotating roller 15 and the winding device is in a relaxed state, and at the same time, the control panel starts the first motor 201, and the film to be coated passes through the two active rollers 14 and is transported to the right. After the first motor 201 is started, the output shaft of the first motor 201 drives the lower active roller 14 to rotate clockwise (from front to back), and the two The two active rollers 14 rotate synchronously in opposite directions through a gear set. When the film enters between the two active rollers 14, the two active rollers 14 transport the film to the right. The film also passes through the lower side of the right guide roller 19, and the film led out by the unwinding roller 16 enters the composite film winding device on the right side of the device. When the leading ends of the two films are fixed in the winding device, the first motor 201 and the second motor 202 stop, and the two clamping rollers 115 clamp the film through the springs of the corresponding sliding blocks 114, and then the control panel controls the first motor 201 and the second motor 202 to rotate. The output shaft of the machine 202 rotates in the opposite direction. Since the one-way wheels 204 are unidirectional, the parts of the two films from the one-way wheels 204 to the winding device do not move. The output shaft of the second motor 202 rotates in the opposite direction to cause the two rotating rollers 15 to transport the film therebetween upward, and the film between the rotating rollers 15 and the one-way wheels 204 is tightened. The film on the upper side of the two rotating rollers 15 is accumulated, and the output shaft of the first motor 201 rotates in the opposite direction to cause the two active rollers 14 to transport the film therebetween to the left, and the film between the active rollers 14 and the one-way wheels 204 is tightened synchronously.

[0028] During the reversal of the second motor 202, the film tightened between the rotating roller 15 and the pressing roller 115 squeezes the sliding frame 110 and the supporting roller 111, and the sliding frame 110 drives the supporting roller 111 and the limiting rod 112 to move to the right, and the spring between the sliding frame 110 and the push plate 113 is compressed. When the sliding frame 110 is in a vertical state with the film on its upper side, the limiting rod 112 squeezes the pressure sensing sheet corresponding to the supporting frame 18, and the second motor 202 stops. At this time, the staff rotates the unloading roller 16 to rewind the film accumulated on the upper side of the rotating roller 15 back to the unloading roller 1 6, when the surface of the film between the active roller 14 and the pressure roller 115 is flat, the first motor 201 stops, and then the control panel starts the feeding device 12, the gluing device 13, the first motor 201 and the second motor 202, and the composite film winding device on the right side of the device is started synchronously, the gluing device 13 evenly applies the adhesive on the upper side of the film, and the film coated with the adhesive moves continuously to the right, and the second motor 202 makes the two rotating rollers 15 rotate in opposite directions to transport the film on the unwinding roller 16 downward, and the pressure roller 115 rotates synchronously, and the moving speed of the two films is the same.

[0029] During the process of the film moving to the right, when the film coated with adhesive moves to the right guide roller 19, the two guide rollers 19 cooperate with the support roller 111 to guide the upper film to make it adhere to the adhesive on the lower film. At the same time, the two clamping rollers 115 on the right press the two laminated films and convey them to the right. The spring connected to the sliding support block 203 presses the corresponding one-way wheel 204 on the surface of the two films, and the one-way wheel 204 itself has unidirectionality. The four one-way wheels 204 work together to clamp the edges of the two films and convey them to the right, so as to achieve the purpose of stably conveying the composite film and avoid the tension of the film causing it to shrink in the opposite direction, which affects the quality of the composite film preparation.

[0030] When the film drawn out from the unwinding roller 16 enters between the two clamping rollers 303, the two clamping rollers 303 move away from each other, the two support blocks 302 on the front side move away from each other and compress the spring connected thereto, the two support blocks 302 on the front side move away from each other and drive the first piston rod 402 to extend from the corresponding first fixed cylinder 401, the space on the left side of the first piston rod 402 in the first fixed cylinder 401 is reduced, the hydraulic oil in the first fixed cylinder 401 enters the second fixed cylinder 404 through the first liquid guide tube 403, the hydraulic oil on the right side of the second piston rod 405 in the second fixed cylinder 404 increases, the second piston rod 405 moves to the left, and the second piston rod 405 drives the push plate 1 13 moves synchronously to the left, the spring between the sliding frame 110 and the corresponding push plate 113 is compressed, and in the process of tightening the film between the rotating roller 15 and the one-way wheel 204, when the sliding frame 110 is perpendicular to the film on its upper side, the sliding frame 110 increases the squeezing force of the film through the supporting roller 111, that is, the tension of the film between the rotating roller 15 and the one-way wheel 204 increases, and the thickness of the film is detected by two clamping rollers 303 and then the position of the push plate 113 is moved, so as to achieve the purpose of controlling the tension when the film is attached to the corresponding film, ensuring that the surface of films of different thicknesses can be kept smooth through stable tension, thereby improving the quality and stability of composite film preparation.

[0031] In the process of the two clamping rollers 303 moving away from each other, the two support blocks 302 on the rear side move away from each other synchronously and compress the spring connected thereto, and the two support blocks 302 in the same square frame 301 on the rear side move away from each other, driving the third piston rod 502 to extend from the third fixed cylinder 501, and the space on the left side of the third piston rod 502 in the third fixed cylinder 501 is reduced, and the hydraulic oil in the third piston rod 502 enters the fourth fixed cylinder 504 through the second liquid guide tube 503, and the hydraulic oil on the upper side of the fourth piston rod 505 in the fourth fixed cylinder 504 increases, and the fourth piston rod 505 moves downward, and the fourth piston rod 505 squeezes the corresponding sliding block 114 on the rear side, and the sliding block 114 drives the upper clamping roller 115 to move downward. The pressing roller 115 on the lower side is moved, and the pressing roller 115 on the lower side causes the two sliding blocks 114 on the lower side to compress the springs connected to them, thereby increasing the clamping force between the two pressing rollers 115. The sliding block 114 causes the corresponding sliding support block 203 to drive the corresponding one-way wheel 204 to move synchronously through the spring, thereby ensuring the tightness of the one-way wheel 204 to the edges of the two films. The corresponding sliding block 114 is squeezed by the fourth piston rod 505 to control the size of the clamping force of the two pressing rollers 115 on the film, so as to achieve the purpose of controlling the clamping force of the laminated film according to the thickness of the film, thereby avoiding the situation where the thickness of the film increases and the clamping force remains unchanged, causing the two films to be loosely fitted, affecting the quality of the composite film packaging.

[0032] When the composite film packaging is completed, the control panel stops the feeding device 12, the gluing device 13, the first motor 201, the second motor 202 and the winding device on the right side of the device, and the operator manually lifts the two one-way wheels 204 on the upper side to cut off the packaging completed part, and at the same time, the output shafts of the first motor 201 and the second motor 202 are rotated in the opposite direction through the control panel. When the two films are moved away from the lower side of the guide roller 19, the sliding plate 17 drives the related parts to move downward and restore to the initial position under the elastic force of the spring connected to it, and the sliding frame 110 moves to the left and restores to the initial position under the elastic force of the spring connected to it. After the unused film is pulled out from between the active rollers 14, the second motor 202 and the first motor 201 stop, and the two support blocks 302 in the same square frame 301 approach each other and restore to their initial positions under the elastic force of the springs connected thereto, and the two clamping rollers 303 approach each other and restore to their initial positions, and the first piston rod 402 moves into the first fixed cylinder 401, and the third piston rod 502 moves into the third fixed cylinder 501, and the hydraulic oil in the second fixed cylinder 404 and the fourth fixed cylinder 504 both perform the above-mentioned reverse movement, and the push plate 113 and the fourth piston rod 505 both restore to their initial positions. At this point, all parts have restored to their initial positions and are ready for next use.

[0033] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 10-12 As shown, it also includes a flattening mechanism 7, which is arranged on the mounting frame 11. The flattening mechanism 7 is used to flatten the film. The flattening mechanism 7 includes a support plate 701, which is fixed to the middle part of the mounting frame 11. The support plate 701 is slidably connected to two sliding curved rods 702 of front and rear mirror images. A spring is fixed between the sliding curved rod 702 and the support plate 701. The left side of the sliding curved rod 702 is rotatably connected to a support shaft 703. The sliding curved rod 702 is hinged with a rotating plate 704. The two rotating plates 704 are located outside the two sliding curved rods 702. Initially, the two rotating plates 704 are in a state of tilting from top to bottom to the outside. The rotating plates 704 are rotatably connected to A plurality of evenly distributed rotating wheels 705, and the evenly distributed rotating wheels 705 on the same rotating plate 704 are jointly provided with a belt, and the contact surface between the corresponding belt and the film on the rotating plate 704 and the contact surface between the support shaft 703 and the film are in the same vertical plane, which is used to make the corresponding belt on the rotating plate 704 in close contact with the adjacent film, and the second fixed cylinder 404 is provided with a pressure control component 8 for controlling the vertical flattening force of the film, and the belts on the two inclined rotating plates 704 are fitted with the film to achieve the purpose of controlling the tension stretching of the film in the front-to-back direction, avoiding wrinkles in the film in the front-to-back direction, and avoiding bubbles in the packaged composite film to affect the packaging quality of the composite film.

[0034] like Figure 10-12As shown, the pressure control assembly 8 includes a guide tube 801, which is connected to the left side of the second fixed cylinder 404, and the two sliding curved rods 702 are fixedly connected to the liquid storage cylinder 802. The opposite sides of the two liquid storage cylinders 802 are connected to the guide tube 801. The liquid storage cylinder 802 is sealed and slidably connected to the sliding rod 803, and the sliding rod 803 penetrates the corresponding sliding curved rod 702. A spring is fixed between the sliding rod 803 and the corresponding rotating plate 704, and the corresponding rotating plate 704 is kept in a state of rotation by the spring of the sliding rod 803. The inclined state ensures that the belt on the rotating plate 704 is stretched in the front-to-back direction during the movement of the film. The guide tube 801, the left side of the second fixed tube 404 and the opposite sides of the two guide tubes 801 are filled with hydraulic oil. The sliding rod 803 drives the movement of the spring connected to it to achieve the purpose of changing the initial inclination angle of the belt on the rotating plate 704, so that the device can control its tension in the front-to-back direction according to the thickness of the film, ensuring the flatness of the surface of the film when it is attached to the adhesive.

[0035] In order to avoid wrinkles in the film rolled up by the unwinding roller 16 or vertical wrinkles in the film during the guiding process of the device, the film being conveyed needs to be stretched in the front-to-back direction to avoid wrinkles or bulges, which will cause bubbles in the composite film after packaging, affecting the quality of composite film packaging and reducing the yield of composite film packaging. The specific operation is as follows: Repeat the above-mentioned film installation steps, taking the unwinding roller 16 on the upper side as an example, when the second motor 202 controls the two rotating rollers 15 to reverse and tighten the film on the left side of the clamping roller 115, the film squeezes the support shaft 703, and the support shaft 703 drives the two sliding bent rods 702 to move to the right. The sliding bent rod 702 slides into the support plate 701 and compresses the spring connected to it. When the second motor 202 stops, the support shaft 703 has a certain squeezing force on the film, and the above-mentioned composite film packaging operation is repeated.

[0036] When the two clamping rollers 303 move away from each other, the second piston rod 405 in the second fixed cylinder 404 moves to the left, and the space on the left side of the second piston rod 405 in the second fixed cylinder 404 is reduced. The hydraulic oil on the left side of the second piston rod 405 in the second fixed cylinder 404 enters the two liquid storage cylinders 802 through the guide tube 801, and the hydraulic oil in the liquid storage cylinder 802 increases. Taking the sliding curved rod 702 on the front side as an example, the sliding rod 803 in the liquid storage cylinder 802 moves forward, and the sliding rod 803 increases the forward swing angle of the rotating plate 704 through the spring. As the upper film is transported downward, a plurality of rotating wheels 705 on the same rotating plate 704 rotate under the transmission of the upper belt and the film. There is a certain squeezing force between the film and the belt. When the film moves, the belts on several adjacent rotating wheels 705 rotate. Since the belts are in an inclined state, when the belts and the film move synchronously, the film moves to the front and rear sides under the guidance of the belts. Under the reaction force of the film, the belts make the corresponding rotating plate 704 swing downward to compress the corresponding spring. When the belt position is stable, the compression amount of the spring between the rotating plate 704 and the corresponding sliding rod 803 remains stable, thereby achieving the purpose of adjusting the tension of the belt on the film in the front and rear directions according to the thickness of the film, so that the film is flattened in the front and rear directions through tension, and wrinkles in the front and rear directions on the film are avoided to affect the final packaging result of the composite film.

[0037] When the device is used and the above operation is repeated for resetting, the second piston rod 405 moves into the corresponding second fixed cylinder 404, the liquid storage cylinder 802 drives the corresponding spring to move back into the corresponding guide tube 801, and the sliding rod 803 and related parts return to their initial positions, waiting for the next use.

The two films are laminated and pass through the two clamping rollers 115 and the four one-way wheels 204, and finally enter the winding device; S2: After the two films enter the winding device, the first motor 201 and the second motor 202 are reversed, the rotating roller 15 and the active roller 14 convey the films in the opposite direction, the films between the one-way wheel 204 and the rotating roller 15 and the active roller 14 are all contracted, and the films between the one-way wheel 204 and the rotating roller 15 are squeezed by the guide roller 19 and the sliding frame 110, and the two films are tightened; S3: When the film passes between the two clamping rollers 303, the two clamping rollers 303 move relative to each other, and the two clamping rollers 303 control the second piston rod 405 through hydraulic oil to drive the push plate 113 to move, and the push plate 113 controls the squeezing force of the support roller 111 on the film through the spring; S4: The two clamping rollers 303 move relative to each other, and the two clamping rollers 303 control the fourth piston rod 505 to squeeze the corresponding sliding block 114 through hydraulic oil, and the squeezing force of the two pressing rollers 115 on the two films therebetween changes; S5: The second fixed cylinder 404 controls the movement of the sliding rod 803 through the hydraulic oil. The sliding rod 803 controls the inclination angle of the corresponding belt on the rotating plate 704 through the spring.
