Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption roller technology, and more specifically, to a vacuum adsorption roller with dual drive control. Background Technology

[0002] In modern industrial production, the TAC membrane manufacturing process includes a wet film production stage. The vacuum adsorption roller is a key component in the wet film production process, and its control methods are crucial for ensuring product quality and improving production efficiency. The following are important control methods for the vacuum adsorption roller in the wet film process of TAC membrane production.

[0003] Due to the wetness of the membrane surface, slippage may occur between the membrane surface and the roller surface when the wet membrane is pulled backward by the roller. The increased friction will affect the membrane quality, causing irreversible damage and resulting in waste membrane and resource waste. Therefore, to solve the above problems, we propose a vacuum adsorption roller with dual drive control. Utility Model Content

[0004] To solve the above problems, this utility model provides a vacuum adsorption roller with dual drive control, adopting the following technical solution:

[0005] A dual-drive controlled vacuum adsorption roller includes two symmetrically distributed drive shafts. The adsorption roller body is sleeved on the sidewall of each drive shaft. A drive motor is connected to one end of each drive shaft. A first support column is provided between the two drive shafts.

[0006] By adopting the above technical solution, when using this equipment, the operator passes the membrane sequentially between the two adsorption roller bodies and the first support column. The first support column and the two adsorption roller bodies support the membrane. Then, a vacuum pump connected to the adsorption roller body on the same side is used to generate negative pressure on the side wall of the adsorption roller body, which adsorbs the membrane. Subsequently, the drive motor drives the transmission shaft on the same side to rotate, and the transmission shaft drives the adsorption roller body on the same side to move, thus transferring the membrane. Through the cooperation of two sets of drive motors, transmission shafts and adsorption roller bodies, the wet membrane has double the adsorption force at this point when the speed of the two adsorption roller bodies is synchronized, eliminating slippage. This dual-drive control ensures the normal process of the membrane and does not affect the quality of the membrane.

[0007] A tension adjustment component is installed above the first support column. The tension adjustment component pushes the first support column up and down, which can adjust the tension of the membrane during delivery. This helps to maintain the tightness of the membrane during delivery and helps to avoid wrinkles during delivery.

[0008] Furthermore, a second support column is provided on each of the two drive shafts on opposite sides, and the two second support columns and the first support column are located below the two drive shafts.

[0009] By adopting the above technical solution, the cooperation of two second support columns and the first support column plays the role of supporting the membrane, which facilitates the subsequent stable transportation of the membrane.

[0010] Furthermore, multiple sets of through holes are provided on the sidewalls of both adsorption roller bodies in a linear array, with the same set of through holes located on the same side of the adsorption roller body in a ring array.

[0011] By adopting the above technical solution, the side wall of the adsorption roller body, through the through holes, facilitates the operation of the adsorption roller body to generate suction, thereby creating negative pressure on the side wall of the adsorption roller body to achieve the effect of adsorbing the film and facilitating the subsequent transport of the film.

[0012] Furthermore, the tension adjustment assembly includes mounting blocks rotatably mounted on both ends of the first support column, a mounting plate above the first support column, a lifting plate below the mounting plate, two symmetrically distributed cylinders at the top of the mounting plate, the piston shafts of the two cylinders slidingly passing through the mounting plate, the ends of the piston shafts of the two cylinders being fixedly connected to the top of the lifting plate, and an elastic component between the two mounting blocks and the lifting plate.

[0013] By adopting the above technical solution, the lifting plate is pushed up and down by the cylinder, the lifting plate pushes the first support column up and down, and the first support column drives the membrane to rise and fall, which plays a role in adjusting the tension of the membrane during delivery. This helps to maintain the tightness of the membrane during delivery and helps to avoid wrinkles during delivery. The mounting block and the lifting plate are equipped with elastic components, which helps to prevent the membrane from being damaged due to excessive pushing force from the first support column.

[0014] Furthermore, the elastic component includes two pillars fixedly installed at the bottom of the lifting plate. Each pillar has a movable groove at its bottom. A support rod is slidably installed in each movable groove. A spring is fixedly connected between the top of each support rod and the inner wall of the top of the movable groove on the same side. The bottom of each support rod is fixedly connected to the top of the mounting block on the same side.

[0015] By adopting the above technical solution, the first support column is driven to rise and fall by a cylinder. The lifting plate pushes the support column, spring and support rod to rise and fall synchronously. When the first support column pushes the membrane to rise and fall, the first support column pushes the support rod to slide in the movable groove on the same side. The support rod pushes the spring on the same side to contract. The first support column has a rebound force under the elastic force of the spring, which achieves a buffering effect and helps to avoid the membrane from being damaged due to excessive pushing force of the first support column.

[0016] Furthermore, two symmetrically distributed sliders are fixedly installed on the top sidewalls of both support rods, and the inner walls of the two movable slots are provided with grooves that match the sliders on the same side.

[0017] By adopting the above technical solution, when the support rod slides in the movable groove on the same side, the support rod slides in the sliding groove on the same side along with the slider. The cooperation between the slider and the sliding groove helps to prevent the support rod from leaving the movable groove on the same side and helps to maintain the stability of the support rod sliding.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] (1) In this utility model, an adsorption roller body is added to the position of the adsorption roller in the wet film process area. Its configuration is the same as the original adsorption roller body, such as vacuum degree, drive motor, speed ratio, etc. When the speed of the two adsorption roller bodies is synchronized, the wet film has double the adsorption force at this point, eliminating slippage. Such dual drive control ensures the normal process of the film and will not affect the quality of the film.

[0020] In summary, the combined effect of these control methods ensures that the adsorption roller body can be effectively produced in wet film applications, while protecting the film from damage during the wet film stage, thereby improving production efficiency and product quality.

[0029] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0030] Please see Figure 1-3 A dual-drive controlled vacuum adsorption roller includes two symmetrically distributed drive shafts 2. Adsorption roller bodies 1 are sleeved on the side walls of both drive shafts 2. A drive motor 3 is connected to one end of each drive shaft 2. A first support column 4 is provided between the two drive shafts 2. Multiple sets of through holes are opened on the side walls of the two adsorption roller bodies 1 in a linear array. The through holes in the same set are located on the same side of the side wall of the adsorption roller body 1 in a ring array.

[0031] When using this equipment, the operator passes the membrane sequentially between the two adsorption roller bodies 1 and the first support column 4. The first support column 4 and the two adsorption roller bodies 1 support the membrane. Then, a vacuum pump connected to the adsorption roller body 1 on the same side is used. The side wall of the adsorption roller body 1 has through holes to facilitate the operation of the adsorption roller body 1 and generate suction, which in turn creates negative pressure on the side wall of the adsorption roller body 1, achieving the effect of adsorbing the membrane and facilitating the subsequent transport of the membrane. Then, the drive motor 3 drives the transmission shaft 2 on the same side to rotate, and the transmission shaft 2 drives the adsorption roller body 1 on the same side to move the membrane. Through the cooperation of the two sets of drive motors 3, transmission shaft 2 and adsorption roller bodies 1, the wet membrane has double the adsorption force at this point when the speed of the two adsorption roller bodies 1 is synchronized, eliminating slippage. This dual-drive control ensures the normal process of the membrane and does not affect the quality of the membrane.

[0032] Each of the two drive shafts 2 has a second support column 5 on its opposite side. The two second support columns 5 and the first support column 4 are located below the two drive shafts 2. Through the cooperation of the two second support columns 5 and the first support column 4, they play the role of supporting the membrane, which facilitates the subsequent stable transport of the membrane.

[0033] A tension adjustment assembly is provided above the first support column 4. The tension adjustment assembly includes mounting blocks 6 rotatably mounted at both ends of the first support column 4. A mounting plate 10 is provided above the first support column 4, and a lifting plate 9 is provided below the mounting plate 10. Two symmetrically distributed cylinders 11 are provided at the top of the mounting plate 10. The piston shafts of the two cylinders 11 slide through the mounting plate 10. The ends of the piston shafts of the two cylinders 11 are fixedly connected to the top of the lifting plate 9. An elastic assembly is provided between the two mounting blocks 6 and the lifting plate 9. The elastic assembly includes two pillars 8 fixedly mounted at the bottom of the lifting plate 9. The bottom of the two pillars 8 is provided with a movable groove 13. A support rod 7 is slidably installed in the two movable grooves 13. A spring 12 is fixedly connected between the top of the two support rods 7 and the inner wall of the top of the movable groove 13 on the same side. The bottom of the two support rods 7 is fixedly connected to the top of the mounting block 6 on the same side.

[0034] The lifting plate 9 is raised and lowered by the cylinder 11, and the lifting plate 9 raises and lowers the first support column 4. The first support column 4 drives the membrane to rise and fall, which helps to adjust the tension of the membrane during delivery. This helps to maintain the tightness of the membrane during delivery and avoids wrinkles. When the lifting plate 9 pushes the column 8, spring 12 and support rod 7 to rise and fall synchronously, and when the first support column 4 pushes the membrane to rise and fall, the first support column 4 pushes the support rod 7 to slide in the movable groove 13 on the same side. The support rod 7 pushes the spring 12 on the same side to retract. The first support column 4 has a rebound force under the elastic force of the spring 12, which achieves a buffering effect and helps to prevent the membrane from being damaged due to excessive pushing force of the first support column 4.

[0035] Two symmetrically distributed sliders are fixedly installed on the top sidewalls of the two support rods 7. The inner walls of the two movable grooves 13 are provided with sliding grooves that match the sliders on the same side. When the support rod 7 slides in the movable groove 13 on the same side, the support rod 7 slides in the sliding groove on the same side with the slider. The cooperation between the slider and the sliding groove helps to prevent the support rod 7 from leaving the movable groove 13 on the same side and helps to maintain the stability of the sliding of the support rod 7.

[0036] The implementation principle of this utility model embodiment is as follows: When using the equipment, the operator passes the membrane sequentially between the two adsorption roller bodies 1 and the first support column 4. The first support column 4 and the two adsorption roller bodies 1 can support the membrane. Then, a vacuum pump connected to the adsorption roller body 1 on the same side is used to generate negative pressure on the side wall of the adsorption roller body 1, which can adsorb the membrane. Then, the drive motor 3 drives the transmission shaft 2 on the same side to rotate, and the transmission shaft 2 drives the adsorption roller body 1 on the same side to move, which can transfer the membrane. Through the cooperation of the two sets of drive motors 3, transmission shaft 2 and adsorption roller bodies 1, when the speed of the two adsorption roller bodies 1 is synchronized, the wet membrane has double the adsorption force at this point, eliminating slippage. This dual-drive control ensures the normal process of the membrane and will not affect the quality of the membrane.

[0037] A tension adjustment component is provided above the first support column 4. The tension adjustment component pushes the first support column 4 up and down, which plays a role in adjusting the tension of the membrane during delivery. This helps to maintain the tightness of the membrane during delivery and helps to avoid wrinkles during membrane delivery.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
