Description

Technical Field

[0001] This application relates to the field of film manufacturing technology, and in particular to a swing roller mechanism and film forming equipment. Background Technology

[0002] To reduce production costs and meet increasingly stringent environmental requirements, dry-process membrane manufacturing is gaining more and more attention. In the dry-process membrane manufacturing process, the membrane tension is relatively low after the powder is rolled into a film. During the unwinding process, the membrane may wrinkle or become loose and deformed due to changes in elongation. At this time, a membrane tension adjustment device is needed to regulate it.

[0003] In related technologies, the oscillating roller in the diaphragm tension regulating device moves vertically. The diaphragm pulls the oscillating roller up and down to keep the diaphragm taut. The up-and-down movement of the oscillating roller is entirely driven by the diaphragm, and the tensile strength of the diaphragm needs to overcome the weight of the oscillating roller. This places high demands on the strength of the diaphragm. The large wrap angle between the oscillating roller and the diaphragm increases friction and can easily cause the diaphragm to experience greater tensile force. Therefore, for dry-process diaphragms, this can easily lead to diaphragm breakage. Summary of the Invention

[0004] This application provides a swing roller mechanism and a film-making device, which can facilitate the adjustment of the state of the film during the transmission process, avoid adverse conditions such as wrinkles, loosening, deformation or even breakage of the film during the transmission process, and thus improve the performance of the film.

[0078] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0079] Currently, the lithium battery industry primarily uses wet slurry mixing to prepare electrodes. Wet slurry mixing requires high-temperature solvent drying, consuming significant energy and polluting the environment. To reduce production costs and meet increasingly stringent environmental requirements, dry film processing technology is gaining importance. Dry film processing is a new lithium-ion electrode manufacturing process that eliminates the use of solvents during electrode fabrication. In dry film manufacturing, the positive and negative electrode active materials, conductive agents, and solid binders are typically mixed directly to form a film. Because the film tension is relatively low after the powder is rolled into a film, changes in elongation during unwinding can cause wrinkles or loosening and deformation, necessitating a film tension adjustment device for regulation.

[0080] In related technologies, the oscillating roller in the diaphragm tension regulating device moves vertically. The diaphragm pulls the oscillating roller up and down to keep the diaphragm taut. The up-and-down movement of the oscillating roller is entirely driven by the diaphragm, and the tensile strength of the diaphragm needs to overcome the weight of the oscillating roller. This places high demands on the strength of the diaphragm. The large wrap angle between the oscillating roller and the diaphragm increases friction and can easily cause the diaphragm to experience greater tensile force. Therefore, for dry-process diaphragms, this can easily lead to diaphragm breakage.

[0081] To address the aforementioned problems, this application provides a novel oscillating roller mechanism and a film-making apparatus incorporating this mechanism. The oscillating roller mechanism includes an oscillating roller assembly, which comprises a driving component, a linkage component, a first guide roller, and a first detection component. The driving component and the first detection component are adapted to be connected to a controller. The driving component and the first detection component are respectively connected to the linkage component, which is also connected to the first guide roller. The first detection component detects the position of the film sheet, which is transferred between the linkage component and the first guide roller and cooperates with the first guide roller and the linkage component, thereby allowing the oscillating roller assembly to adjust the tension of the film sheet. This application embodiment helps to adjust the state of the film sheet during the transfer process, preventing defects such as wrinkles, loosening, deformation, or even breakage.

[0082] The following detailed description, in conjunction with the accompanying drawings, describes the oscillating roller mechanism and the film-making equipment having the oscillating roller mechanism provided in the embodiments of this application.

[0083] Figure 1 This is a schematic diagram of the structure of the swing roller mechanism and the diaphragm provided in the embodiments of this application. Figure 2 This is a schematic diagram of a swing roller assembly in a swing roller mechanism provided in an embodiment of this application. Figure 3 for Figure 2 The front view. Figure 4 for Figure 2 Top view. Figure 5 for Figure 2 The left view. Figure 6 for Figure 2 The right view. Figure 7 for Figure 2 Exploded view.

[0084] Reference Figure 1 As shown, this application embodiment provides a swing roller mechanism 100, which may include a swing roller assembly 110. Specifically, see... Figures 2 to 7 As shown, the swing roller assembly 110 may include a drive component 111, a linkage component 112, a first guide roller 113, and a first detection component 114, wherein the drive component 111 and the first detection component 114 are adapted to be connected to a controller.

[0085] The drive component 111 and the first detection component 114 are respectively connected to the linkage assembly 112, and the linkage assembly 112 is also connected to the first roller 113.

[0086] In some embodiments, the driving member 111 is connected to one end of the linkage assembly 112, and the other end of the linkage assembly 112 is connected to the first detection member 114. Specifically, the driving member 111 may be driven to one end of the linkage assembly 112, the other end of the linkage assembly 112 may be fixedly connected to the first detection member 114, and the first roller 113 may be rotatably connected to the linkage assembly 112.

[0087] Alternatively, in some other embodiments, the drive element 111 and the first detection element 114 may be connected to the same end of the linkage assembly 112.

[0088] In this embodiment of the application, the first detection element 114 is used to detect the position of the diaphragm 200 that is transmitted between the linkage assembly 112 and the first roller 113 and cooperates with the first roller 113 and the linkage assembly 112, so that the swing roller assembly 110 adjusts the tension of the diaphragm 200.

[0089] See Figure 2 As shown in the embodiment of this application, the first detection element 114 may include a positioning element 1141 and a first sensor 1142. The first sensor 1142 is connected to the controller, and one end of the linkage component 112 is connected to the positioning element 1141. When the driving element 111 drives the linkage component 112 to rotate, the first sensor 1142 is used to detect the position change of the positioning element 1141.

[0090] Continue to refer to Figure 2 As shown in the embodiment of this application, the linkage component 112 may include a connecting shaft 1121 and a swing roller 1122. The driving member 111 is connected to one end of the connecting shaft 1121, the other end of the connecting shaft 1121 is connected to the positioning member 1141, the first roller 113 is sleeved on the connecting shaft 1121 and connected to the connecting shaft 1121, and both ends of the swing roller 1122 are connected to the connecting shaft 1121.

[0091] In some embodiments, the oscillating roller 1122 may be connected to the connecting shaft 1121 via a first fastener 130.

[0092] like Figures 3 to 6 As shown, the swing roller assembly 110 may further include a first support 117 and a first fixing plate 118. The first support 117 serves to support the entire swing roller assembly 110, and the first fixing plate 118 is fixed to one end of the first support 117. Figure 7 As shown, a first mounting base 1143 is also provided on the first support 117, and the first mounting base 1143 is used to install the first detection component 114.

[0093] See also Figure 7 As shown, the swing roller assembly 110 may also include a second mounting base 119, which is fixed to the first fixing plate 118 and is used to mount the drive component 111.

[0094] Figure 8 This is a schematic diagram of the tension component in the swing roller mechanism provided in the embodiments of this application. Figure 9 for Figure 8 Exploded view.

[0095] In this embodiment, the swing roller mechanism 100 may further include a tension component 120. (See also...) Figure 8 and Figure 9 As shown, the tension assembly 120 may include a second guide roller 121 and a second detection element 122, wherein the second detection element 122 is connected to the second guide roller 121. The second detection element 122 is connected to a controller. The second detection element 122 is used to detect the tension of the diaphragm 200 that is transmitted through and cooperates with the second guide roller 121.

[0096] Continue to refer to Figure 8 and Figure 9 As shown, the tension assembly 120 may further include a second support 123 and a second fixing plate 124. The second support 123 serves to support the entire tension assembly 120, and the second fixing plate 124 is fixed to one end of the second support 123. Figure 8 As shown, the second roller 121 is fixed to the second fixed plate 124.

[0097] It is understood that in some embodiments, the second detection element 122 can be a second sensor. The second detection element 122 detects that the tension of the diaphragm 200 exceeds a preset range and transmits the signal to the controller. The controller controls the drive element 111 to drive the linkage assembly 112 to swing, so as to control the tension of the diaphragm 200 to reach a suitable range. When the first sensor 1142 detects that the distance between the positioning element 1141 and the first sensor 1142 exceeds a preset value, it proves that the adjustment range of the swing roller assembly 110 has been exceeded. At this time, the signal of the first sensor 1142 is sent to the controller, and the controller controls the film forming mechanism 310 to accelerate or decelerate, thereby dynamically adjusting the tension of the film 200 to a suitable range to prevent the film 200 from wrinkling or breaking.

[0098] In this embodiment, the position signal of the oscillating roller assembly 110 is fed back to the controller of the oscillating roller mechanism 100. The controller controls the rotation speed of the rollers in the film forming mechanism 310 and the rollers in the pressure roller mechanism 320 to achieve a speed closed loop between the rollers and the oscillating roller assembly 110. In addition, the tension of the film 200 measured by the second detection element 122 is fed back to the controller. The controller controls the torque of the drive element 111 to achieve a torque closed loop between the tension assembly 120 and the drive element 111.

[0099] In this way, by actively adjusting the tension of the diaphragm 200 using a dual closed-loop method, the state of the diaphragm 200 during transmission can be better regulated, preventing the diaphragm 200 from wrinkling or loosening due to changes in elongation during transmission, and preventing the diaphragm 200 from breaking due to changes in transmission speed within the tension range. At the same time, it is beneficial for the cutter to cut the diaphragm 200 evenly during the cutting process, thereby improving the performance of the diaphragm 200.

[0100] In the embodiments of this application, such as Figures 10 to 12 As shown, the rotation center of the positioning member 1141 (i.e., the rotation center A of the positioning member) and the rotation center of the connecting shaft 1121 (i.e., the rotation center B of the connecting shaft) can be set out to be offset.

[0101] In some embodiments, the positioning member 1141 can be an irregularly shaped part; for example, the shape of the positioning member 1141 can be as follows: Figure 11 or Figure 12 The fan-shaped structure shown has a positioning element 1141 whose main function is to change the distance between the positioning element 1141 and the first sensor 1142.

[0102] It should be noted that irregular parts refer to components that differ significantly from traditional standard parts in terms of shape, size, and structure.

[0103] In the embodiments of this application, see Figure 11 or Figure 12 As shown, the positioning member 1141 may include a rotating part 1141a, a connecting plate 1144 and an arc plate 1141d connected together, wherein one end of the connecting plate 1144 is connected to the rotating part 1141a and the other end of the connecting plate 1144 is connected to the arc plate 1141d.

[0104] In one possible implementation, the connecting plate 1144 may include a first connecting plate 1141b and a second connecting plate 1141c. One end of the first connecting plate 1141b is connected to the rotating part 1141a, and the other end of the first connecting plate 1141b is connected to the arc-shaped plate 1141d. One end of the second connecting plate 1141c is connected to the rotating part 1141a, and the other end of the second connecting plate 1141c is connected to the arc-shaped plate 1141d.

[0105] In this embodiment of the application, a second through hole 1141f is provided on the rotating part 1141a, and the connecting shaft 1121 can pass through the second through hole 1141f.

[0106] In addition, in some embodiments, the positioning member 1141 may also have a hollow portion 1141e.

[0107] In this embodiment, the arc plate 1141d can cooperate with the first sensor 1142. Specifically, the swing amplitude of the positioning member 1141 and the outer contour shape of the side of the arc plate 1141d facing the first sensor 1142 can be matched with the measurement range of the first sensor 1142.

[0108] Taking the shape of the positioning element 1141 as a fan-shaped structure as an example, it can be understood that the swing amplitude of the fan-shaped positioning element 1141 and the arc surface design of the arc plate 1141d are matched with the tension of the diaphragm 200 or the measurement range of the first sensor 1142.

[0109] This section describes the closed-loop process and principle between the oscillating roller and the rolling mill. When the diaphragm 200 changes, the oscillating roller oscillates accordingly, causing the positioning component 1141 to rotate. The first sensor 1142 then receives the signal and feeds it back to the controller. If the change in the diaphragm 200 is less than the stroke range of the oscillating roller, the change in the diaphragm 200 is absorbed by the oscillating roller; if the change in the diaphragm 200 is greater than the stroke range of the oscillating roller, the controller controls the drive component 111 to increase or decrease speed.

[0110] Specifically, the positioning element 1141 and the swing roller simultaneously perform arc-shaped movements around the connecting shaft 1121. The tension change of the diaphragm 200 on the swing roller causes the swing roller to perform arc-shaped movements around the connecting shaft 1121. The swing roller drives the positioning element 1141 to rotate. The positioning element 1141 and the connecting shaft 1121 have an eccentric structure. The second sensor detects changes in the distance between itself and the positioning element 1141, providing feedback on the change in the position of the swing roller, thus allowing the system to identify the position of the diaphragm 200. When the position of the diaphragm 200 exceeds the upper or lower limits set by the controller, the controller will control the front and rear rollers to accelerate or decelerate.

[0111] This section describes the closed-loop process and principle between the swing roller and the second sensor. First, the torque reference value of the drive component 111 is set. The second sensor detects the tension of the diaphragm 200 and feeds it back to the controller. The controller changes the output torque of the drive component 111 with reference to the actual tension. Then, the drive component 111 adjusts the torque reference value sequentially.

[0112] It should be noted here that, as Figure 13 As shown, the lever arm of the swing roller assembly is L. In this embodiment, the torque required by the diaphragm 200 is equal to the torque of the drive member 111 multiplied by the lever arm L of the swing roller assembly, and then multiplied by a percentage.

[0113] like Figure 14 As shown, the diaphragm 200 passes under the second guide roller 121, generating an upward tension between it and the guide roller. The second sensor can measure the magnitude and change of the tension of the diaphragm 200. Before the diaphragm 200 is transmitted, a suitable swing force value for the diaphragm 200 is set and entered into the program. When the tension detected by the second sensor is less than the set value, the controller controls the drive component 111 to increase the torque output (increasing the swing force by a certain proportion); when the second sensor detects that the tension is greater than the set value, the controller controls the drive component 111 to decrease the output torque (decreasing the swing force by a certain proportion), so that the swing force of the swing roller is stabilized near the set value.

[0114] In this embodiment of the application, the swing roller assembly 110 may further include a weight 115 and a second fixing member 116. The weight 115 is connected to one end of the second fixing member 116, and the other end of the second fixing member 116 is connected to the connecting shaft 1121.

[0115] The connecting shaft 1121 is also provided with a first through hole 1121a, through which the first fixing member 130 and the second fixing member 116 are connected. And / or, the first fixing member 130 and the second fixing member 116 are an integral connecting structure passing through the first through hole 1121a.

[0116] In some embodiments, there may be two second fixing members 116 and two weight members 115. The two weight members 115 are respectively connected to one end of the two second fixing members 116, and the other end of each of the two second fixing members 116 is connected to the connecting shaft 1121. Similarly, the connecting shaft 1121 may have two through holes 1121a.

[0117] The total weight of the two weights 115 can be the same as the weight of the swing roller 1122. The weight of the weight is the same as the weight of the swing roller 1122, and the weight can play a balancing role. In this way, the swing roller 1122 can remain stable in space after rotating one revolution.

[0118] In this embodiment of the application, there can be two second detection elements 122, and the two second detection elements 122 can be connected to the two ends of the second roller 121 respectively.

[0119] like Figure 15 and Figure 16 As shown in this embodiment, when the diaphragm 200 cooperates with the second roller 121, a mating portion 1131 can be formed on the second roller 121. The central angle of the mating portion 1131 on the second roller 121 (i.e., the central angle O of the mating portion) can be 10°-90°. Compared with the 180° wrap angle formed between the diaphragm 200 and the swing roller assembly 110 in the related art, this embodiment reduces the wrap angle between the diaphragm 200 and the swing roller assembly 110, thereby reducing friction.

[0120] It should be noted that the wrap angle refers to the central angle subtended by the contact arc between the diaphragm 200 and the roller. The size of the wrap angle reflects the length of the contact arc between the diaphragm 200 and the roller surface. The smaller the wrap angle, the shorter the contact arc, the smaller the total frictional force generated between the contact surfaces, and the smaller the tension transmitted by the diaphragm 200. The dry-process diaphragm 200 is a self-supporting membrane with low tension. Therefore, during transmission, the wrap angle between the diaphragm 200 and the roller should be minimized to reduce the increased tension on the diaphragm 200 and prevent tearing or breakage.

[0121] For example, in the embodiments of this application, the central angle of the mating part 1131 on the second roller 121 can be a range of 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90° or any two of them. The embodiments of this application do not limit this, nor are they limited to the above examples.

[0122] It should be noted that the numerical values ​​and ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0123] In this embodiment, the oscillating roller 1122 can be a hollow roller. By designing the oscillating roller 1122 as a hollow roller, the mass of the oscillating roller 1122 can be reduced, thereby reducing the mass of the oscillating roller mechanism 100, and also reducing the moment of inertia of the oscillating roller during oscillation.

[0124] In this embodiment, the oscillating roller 1122 can be made of a lightweight material. Lightweight materials have low density.

[0125] Similarly, the first guide roller 113 can be made of a lightweight material, and the second guide roller 121 can also be made of a lightweight material. Likewise, the first guide roller 113 can be a hollow roller, and the second guide roller 121 can also be a hollow roller. By designing the first guide roller 113 and the second guide roller 121 as hollow rollers, the mass of the first guide roller 113 and the second guide roller 121 can be reduced, thereby reducing the mass of the swing roller mechanism 100, and consequently reducing the inertia generated by the swing roller mechanism 100 during swinging.

[0126] In the embodiments of this application, the lightweight material can be one or more of carbon fiber, aluminum, or polystyrene.

[0127] In this embodiment of the application, the length of the swing roller 1122 can be 40mm-2000mm. Exemplarily, the length of the swing roller can be 40mm, 80mm, 400mm, 800mm, 1200mm, 1600mm, 2000mm or any combination thereof. This embodiment of the application does not limit this, nor is it limited to the above example.

[0128] Similarly, the length of the first guide roller 113 can be 40mm-2000mm. For example, the length of the first guide roller 113 can be 40mm, 80mm, 400mm, 800mm, 1200mm, 1600mm, 2000mm or any combination thereof. The embodiments of this application do not limit this, nor are they limited to the above examples.

[0129] The length of the second guide roller 121 can also be 40mm-2000mm. For example, the length of the second guide roller 121 can be 40mm, 80mm, 400mm, 800mm, 1200mm, 1600mm, 2000mm or any combination thereof. The embodiments of this application do not limit this, nor are they limited to the above examples.

[0130] In this embodiment, the cross-sectional radius of the swing roller 1122 can be 2mm-60mm. Exemplarily, the cross-sectional radius of the swing roller can be 2mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm or any combination thereof, and this embodiment does not limit it, nor is it limited to the above example.

[0131] Similarly, the cross-sectional radius of the first guide roller 113 can be 2mm-60mm. For example, the cross-sectional radius of the first guide roller 113 can be 2mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm or any combination thereof. The embodiments of this application do not limit this, nor are they limited to the above examples.

[0132] The cross-sectional radius of the second guide roller 121 can also be 2mm-60mm. For example, the cross-sectional radius of the second guide roller 121 can be 2mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm or any combination thereof. The embodiments of this application do not limit this, nor are they limited to the above examples.

[0133] Additionally, it should be noted here that, see Figure 7 As shown, the two ends of the oscillating roller 1122 can be provided with first bearings 1122a, and the two ends of the first guide roller 113 can be provided with second bearings 113a. See [reference needed]. Figure 9 As shown, third bearings 121a can be provided at both ends of the second roller 121.

[0134] The first bearing 1122a, the second bearing 113a, and the third bearing 121a can be low-damping bearings to reduce friction. For example, in some embodiments, the first bearing 1122a, the second bearing 113a, and the third bearing 121a can be low-damping ceramic bearings. The rolling balls in ceramic bearings have a lower density and are lighter than steel, thus reducing the centrifugal friction on the outer rings during rotation. Furthermore, ceramic bearings are corrosion-free, reducing the increase in damping during rotation caused by corrosion.

[0135] In this embodiment, the driving component 111 can be a motor, specifically, the driving component 111 can be a servo motor. The servo motor includes three operating modes: position mode, speed mode, and torque mode, and the selection of the mode depends on the actual application scenario.

[0136] Taking a servo motor in position mode as an example, a servo motor can include a position sensor (such as an encoder), a controller, a driver, and the motor itself. The position sensor detects the actual position of the motor shaft and converts the position signal into an electrical signal, which is then sent to the controller. During operation, the controller sends a position command to the servo motor, which then controls the motor to reach the specified position through its internal position control system. As the motor approaches the target position, it slows down and eventually stops at the target position. The control algorithm for a servo motor in position mode typically employs a PID (Proportional-Integral-Derivative) control algorithm. The controller calculates the position deviation based on the position command and the actual position, then generates a control signal to control the motor's operation via the driver, thereby eliminating the position deviation.

[0137] Taking a servo motor in speed mode as an example, a servo motor can include a speed sensor, a controller, a driver, and the motor itself. The speed sensor detects the actual speed of the motor shaft and converts the speed signal into an electrical signal, which is then sent to the controller. During operation, the controller sends a speed command, and the servo motor controller adjusts the motor control signal based on the feedback signal to control the motor to output the specified speed. The control algorithm for the servo motor in speed mode also uses the PID control algorithm. The controller calculates the speed deviation based on the speed command and the actual speed, then generates a control signal, which controls the motor's operation through the driver to eliminate the speed deviation.

[0138] Taking a servo motor in torque mode as an example, a servo motor can include a torque sensor (or torque measured indirectly via current sensing), a controller, a driver, and the motor itself. The torque sensor or current sensing device detects the actual torque of the motor shaft and converts the torque signal into an electrical signal, which is then sent to the controller. During operation, the controller sends a torque command, and the servo motor controller adjusts the motor control signal through its internal torque control system to control the motor to output the specified torque. The control algorithm for a servo motor in torque mode can employ either a PID control algorithm or a fuzzy control algorithm. The PID algorithm achieves precise control of the motor torque by adjusting the proportional, integral, and derivative coefficients. The fuzzy control algorithm utilizes fuzzy logic to process torque deviations, achieving more flexible and adaptable torque control.

[0139] In practical applications, servo motors can switch between these three modes according to the specific needs and performance requirements of the equipment to achieve different control methods and effects. Furthermore, by optimizing the control algorithm and closed-loop control system, the control accuracy and stability of the servo motor can be further improved.

[0140] The oscillating roller mechanism uses a servo motor to precisely control the position, speed, and torque of the oscillating roller. The servo motor itself has the function of emitting pulses. Upon receiving a pulse, the servo motor rotates by the angle of that pulse, thus achieving displacement. Therefore, for each angle rotation, the servo motor emits a corresponding number of pulses, forming a feedback loop with the received pulses. In this way, the system knows how many pulses were sent to the servo motor and how many pulses were received, allowing for precise control of the motor's rotation and achieving precise positioning down to 0.0001mm. This invention uses a servo motor for closed-loop control: In closed loop 1, the servo motor controls the rotational speed of the roller to maintain the rolling speed of the diaphragm 200 at a stable state. That is, the speed closed loop is achieved in the speed mode of the roller servo. In closed loop 2, the servo motor controls the torque of the oscillating roller to maintain the tension on the diaphragm 200 at a stable state, ensuring that the torque and tension are within the bearing capacity of the diaphragm 200 and preventing tearing. That is, the tension closed loop is achieved in the torque mode of the servo motor.

After the film forming mechanism 310 forms a film 200, the film 200 extends into the swing roller mechanism 100 to adjust the tension state of the film 200 during the transmission process.

[0143] In this embodiment, by providing the aforementioned swing roller mechanism 100 in the film-forming equipment 300, the swing roller mechanism 100 can adjust the tension state of the film 200 during the transmission process, thereby avoiding adverse conditions such as wrinkles, loosening, deformation, or even breakage of the film 200 during the transmission process, and thus improving the performance of the film 200 produced by the film-forming equipment 300.

[0146] In this embodiment of the application, the film forming equipment 300 may further include a controller (not shown in the figure), which is used to receive signals from the swing roller mechanism 100 and to control the operation of the swing roller mechanism 100.

[0147] Additionally, it is understood that in this embodiment, the position signal of the oscillating roller 1122 in the oscillating roller mechanism 100 can be fed back to the controller, which controls the rotation speed of the rollers in the film forming mechanism 310 and / or the rollers in the pressure roller mechanism 320, so as to control the transmission speed of the film 200.
