Description

Technical Field

[0001] The present invention relates to the technical field of capacitor film production, and in particular to a capacitor film reeling and unreeling tension adjustment mechanism and an adjustment method. Background Art

[0002] In the production and processing of capacitor film, winding and unwinding operations are an indispensable link. Due to its unique electrical and physical properties, capacitor film is widely used in electronics, communications, energy storage and other fields. However, during the winding and unwinding process, capacitor film is prone to problems such as uneven tension, curling, and stretching deformation due to the elasticity and viscosity of the material itself and the influence of external environmental factors, thus affecting the quality of the product and subsequent processing effects.

[0003] Most traditional capacitor film winding and unwinding equipment adopts a simple mechanical structure, such as a single winding roller and a drive motor, and lacks an accurate tension adjustment mechanism. When the existing winding device is in use, the capacitor film is wound on the receiving shaft. As the capacitor film is continuously wound, the outer diameter of the capacitor film roll will gradually increase, so the edge line speed of the capacitor film roll will gradually change. The change in line speed will cause a speed difference between the winding speed and the conveying speed of the capacitor film. As the outer diameter of the capacitor film roll increases, the tension of the capacitor film will gradually increase. If the diameter of the capacitor film roll is large enough, it will cause the capacitor film to break, resulting in poor stability in use. Summary of the invention

[0018] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figures 1 to 7 As shown, the capacitor film reeling and unreeling tension adjustment mechanism of the present invention comprises: A support base 1 is fixedly arranged on the ground, and two sets of winding support plates 11 are fixedly installed on the support base 1; The winding roller 2 is rotatably arranged between the two sets of winding support plates 11, and is used to wind up the capacitor film. The winding roller 2 is provided with two quick-change mechanisms; Two transmission wheels 3 are rotatably disposed on two winding support plates 11 respectively, and are used to drive the winding roller 2 to rotate; Two linear speed adjustment mechanisms 4 are symmetrically arranged on the support base 1, and are used to control the rotation of the two transmission wheels 3 and adjust the rotation speed of the transmission wheels 3; A pressure roller 5 is rotatably arranged between the two linear speed adjustment mechanisms 4, and the pressure roller 5 is arranged below the winding roller 2; Wherein, the line speed adjustment mechanism 4 comprises: The motor 41 is fixedly mounted on the winding support plate 11; The transmission shaft 42 is tightly connected to the output end of the motor 41. The transmission shaft 42 is a hexagonal prism, and a sliding sleeve is set on the transmission shaft 42. The driving wheel 43 is rotatably arranged on the sliding sleeve and driven to rotate by the motor 41. The driving wheel 43 is in contact with the side end of the transmission wheel disc 3 to drive the transmission wheel disc 3 to rotate; The bearing slider 44 is slidably disposed in the winding support plate 11 and fixedly connected to the sliding sleeve. The pressure roller 5 is rotatably mounted on the bearing slider 44. The working process and principle of the device are as follows: in the initial state, the capacitor film passes over the pressure roller 5, is slightly flattened by the pressure roller 5, and then is wound around the winding roller 2; the motor 41 is in standby mode, and the transmission shaft 42, the driving wheel 43 and the driving wheel disc 3 are all stationary; the bearing slider 44 and the pressure roller 5 thereon are maintained at an appropriate height according to the initial set position; when it is necessary to start winding, the motor 41 is started, and the driving wheel 43 is driven to rotate through the transmission shaft 42; the driving wheel 43 is in contact with the side end of the driving wheel disc 3, thereby driving the driving wheel disc 3 to rotate; the driving wheel disc 3 further drives the winding roller 2 to rotate and starts to wind up the capacitor film; as the outer diameter of the capacitor film roll on the winding roller 2 gradually increases, the edge linear speed of the capacitor film roll will change. changes, resulting in increased tension; at the same time, the capacitor film roll with an increased outer diameter will push the pressure roller 5 downward, and then the pressure roller drives the driving wheel 43 to slide downward along the transmission shaft 42 through the bearing slider 44. As the driving wheel 43 gradually moves away from the center of the transmission wheel 3, the rotation speed of the transmission wheel 3 will be fine-tuned to adapt to different tension requirements; the hexagonal prism design of the transmission shaft 42 and the sliding function of the sleeve are utilized to achieve fine-tuning of the contact position between the driving wheel 43 and the transmission wheel 3, and then fine-tune the rotation speed of the transmission wheel 3 to adapt to different tension requirements; precise control of the tension in the process of winding the capacitor film is achieved, effectively solving the existing problems of uneven tension, curling, stretching deformation, etc., and improving the winding stability of the capacitor film.

[0020] After the capacitor film is wound up, the capacitor film roll and the winding roller 2 used for the winding operation need to be disassembled and replaced with a new winding roller 2 to facilitate the next winding operation. Therefore, a quick-change mechanism is required to achieve the effect of quickly disassembling and assembling the winding roller 2. The quick-change mechanism includes: The reel clamping block 21 is fixedly mounted on the reeling roller 2; The quick-change seat 22 is rotatably disposed on the winding support plate 11; Two quick-change clamping blocks 23 are arranged on the quick-change seat 22 to slide relative to each other up and down, and are used to clamp the reel clamping block 21; The locking sleeve 24 is slidably mounted on the quick-change seat 22 and is used to clamp the reel clamping block 21 and the quick-change clamping block 23; A fixing bolt 25 is threadedly inserted into the locking sleeve 24 and is used to lock and fix the locking sleeve 24; The working process and principle of the quick-change mechanism are as follows: the reel clamping block 21 has been pre-fixed and installed on the winding roller 2, serving as a key component connecting the winding roller 2 with the quick-change mechanism; the quick-change seat 22 is rotatably set on the winding support plate 11, providing a stable installation platform for the quick-change clamping block 23 and the locking sleeve 24; when the winding roller 2 needs to be replaced or installed, first align the reel clamping block 21 of the winding roller 2 with the opening of the quick-change seat 22; then, operate the quick-change clamping block 23 to slide up and down on the quick-change seat 22 relatively, until the quick-change clamping block 23 clamps the reel clamping block 21; then, slide the locking sleeve 24 onto the quick-change seat 22, and use it to clamp the reel clamping block 21 and the quick-change clamping block 23 to ensure close contact and stable connection between them; finally After that, by rotating the fixing bolt 25, it is threadedly inserted into the locking sleeve 24, and the locking sleeve 24 is locked and fixed, thereby completing the firm connection between the winding roller 2 and the quick-change mechanism; when the capacitor film is wound up and needs to be replaced, the fixing bolt 25 is loosened, and then the locking sleeve 24 is horizontally slid to make the locking sleeve 24 separate from the state of tightening the reel clamping block 21 and the quick-change clamping block 23, and then the two quick-change clamping blocks 23 are pulled in the upward and downward directions respectively to separate the quick-change clamping blocks 23 from the reel clamping block 21, and then the capacitor film roll is pulled horizontally to pull the reel clamping block 21 out of the quick-change seat 22; the quick-change mechanism realizes the fast and stable connection between the winding roller 2 and the quick-change mechanism, making the replacement of the winding roller 2 simple and quick, and improving the convenience of operation.

[0021] The quick-change mechanism also includes: The ejector plate 26 is horizontally slidably disposed inside the quick-change seat 22, and the upper and lower ends of the ejector plate 26 are respectively obliquely clamped and slidably matched with the two quick-change clamping blocks 23; The first elastic spring sheet 27 is fixedly mounted in the quick-change seat 22 and is fixedly connected to the ejection plate 26; The reel block 21 is pushed into the quick-change seat 22; in this process, the ejector plate 26 is squeezed by the reel block 21 and moves inward, while compressing the first elastic spring sheet 27; when the reel block 21 completely enters the quick-change seat 22, the ejector plate 26 is also pressed inward to overcome the elastic force of the first elastic spring sheet 27, and when the quick-change clamp 23 completely clamps the reel block 21, the ejector plate 26 also reaches the end of its moving stroke, and the ejector plate 2 The upper and lower ends of the spool 26 are respectively engaged with the two quick-change clamps 23 in an oblique manner, so that the quick-change clamps 23 move inward, thereby clamping the reel clamp 21; to remove the reel clamp 21 from the quick-change seat 22, it is only necessary to remove the lock sleeve 24, and then under the elastic force of the first elastic spring sheet 27, the ejection plate 26 will be pushed outward, and then the upper and lower ends of the ejection plate 26 are respectively engaged with the two quick-change clamps 23 in an oblique manner, so that the quick-change clamp 23 moves inward. The ejector plate 26 moves outward to release the reel block 21, and then remove the reel 2; the oblique clamping structure at the upper and lower ends of the ejector plate 26 enables the two quick-change clamps 23 to slide toward or away from each other when the ejector plate 26 moves, thereby realizing the function of clamping or releasing the reel block 21; the first elastic spring sheet 27 provides an outward elastic force for the ejector plate 26, so that it maintains the initial state when there is no external force; when it is necessary to clamp the reel block 21, it is necessary to overcome this elastic force to push the ejector plate 26; through the cooperation of the ejector plate 26 and the quick-change clamp 23, and the locking effect of the locking sleeve 24 and the fixing bolt 25, the quick replacement function of the reel 2 is realized, and the work efficiency is improved; the ejector plate 26 and the first elastic spring sheet 27 in the quick-change mechanism realize the quick clamping and releasing function of the reel 2 through the principle of oblique clamping sliding cooperation and elastic drive, which provides convenience for the reeling and unreeling operation of the capacitor film.

[0022] like Figure 1 to Figure 2 As shown, the winding roller 2 also includes: The pressing plate 2a is covered on the winding roller 2 and is used to press and fix the end of the capacitor film; the pressing plate 2a cooperates with the winding roller 2 to form a complete circumferential surface; Place one end of the capacitor film to be rolled up at the starting position of the winding roller 2 to ensure that the end of the film is flat; cover the end of the winding roller 2 with the pressure plate 2a to ensure that the pressure plate 2a tightly presses the end of the capacitor film; ensure that the pressure plate 2a is completely in contact with the end surface of the winding roller 2 without any gap or looseness to prevent the capacitor film from deflecting or curling during the winding process; the pressure plate 2a plays a key role in the initial stage of winding, ensuring that the end of the capacitor film is always in contact with the winding roller 2 during the winding process to prevent loosening or deviation; as the winding proceeds, the capacitor film gradually covers the entire winding roller 2, and the effect of the pressure plate 2a gradually weakens, but it can still provide additional stability; the pressure plate 2a cooperates with the winding roller 2 to form a complete circular surface, ensuring that the capacitor film can be flatly attached to the winding roller 2 at the initial stage of winding to avoid curling or wrinkles; the additional stability provided by the pressure plate 2a helps to improve the overall quality of the capacitor film during the winding process and reduce defects caused by loose ends.

[0023] A finger-holding groove is provided on the pressure plate 2a; the finger-holding groove provides a convenient fulcrum, so that the operator can easily pick up, move or install the pressure plate 2a; when the pressure plate 2a needs to be covered on the winding roller 2 to compress the capacitor film, the operator can apply force through the finger-holding groove to make the pressure plate 2a fit firmly on the winding roller, so that the operator can complete the installation and removal of the pressure plate 2a more easily and safely, which is convenient for operation, enhances stability and improves safety.

[0024] like Figure 6 As shown, the winding roller 2 also includes: The locking plate 2b is fixedly mounted on the pressing plate 2a; The rotating rod slide 2c is slidably arranged on the locking plate 2b; A rotating rod 2d is rotatably mounted on the rotating rod slide 2c; A locking groove 2e is arranged inside the winding roller 2, and the top of the locking groove 2e is arranged in a wave shape; The second elastic spring sheet 2f is fixedly mounted on the lock plate 2b and is fixedly connected to the rotating rod slide 2c; The locking plate 2b is fixedly mounted on the pressure plate 2a, and the two form a whole; the rotating rod slide 2c can slide freely up and down on the locking plate 2b, and at the same time, it is subjected to the elastic force of the second elastic spring sheet 2f to maintain an upward initial position; the rotating rod 2d is rotatably mounted on the rotating rod slide 2c and can rotate around its axis; the locking groove 2e is arranged inside the winding roller 2, and its top end is designed to be wavy, and there is an inclined guide surface at the top end of the inner end for guiding the rotating rod 2d to enter or exit the locking position; the second elastic spring sheet 2f is fixedly mounted on the locking plate 2b and connected to the rotating rod slide 2c to provide an upward elastic force for the rotating rod slide; when it is necessary to fix the end of the capacitor film When fixed on the winding roller 2, first, the pressure plate 2a and the locking plate 2b are covered on the winding roller, so that the pressure plate 2a and the winding roller 2 cooperate to form a complete circular surface; then, the rotating rod slide 2c is pushed downward through the locking groove 2e and the rotating rod 2d to overcome the elastic force of the second elastic spring sheet 2f; as the rotating rod slide 2c descends, the rotating rod 2d will also descend and slide along the end surface of the locking groove 2e; the rotating rod 2d is stuck in the groove of the locking groove 2e, and at the same time, under the elastic force of the second elastic spring sheet 2f, the rotating rod 2d is fitted with the locking groove 2e to realize the locking function, which not only improves the production efficiency, but also ensures the stability of the capacitor film during the winding process.

[0025] like Figure 7 As shown, the transmission wheel 3 also includes: The dynamometer 31 is fixedly mounted in the transmission wheel 3; The torsion spring 32 is fixedly mounted on the side end of the quick-change seat 22 and is fixedly connected to the dynamometer 31; In this mechanism, one end of the torsion spring 32 is fixedly connected to the quick-change seat 22, and the other end is connected to the dynamometer 31; when the capacitor film generates tension during the winding process, this tension will be transmitted to the torsion spring 32 through the transmission wheel 3, causing it to twist; the degree of torsion of the torsion spring 32 is proportional to the torsional energy stored in it, and this energy is transmitted to the dynamometer 31 through the connection between the torsion spring and the dynamometer 31, so that it can measure this force; the dynamometer 31 and torsion spring 32 in the transmission wheel 3 work together to indirectly measure the tension of the capacitor film during the winding process by measuring the elastic force of the torsion spring, and feed this information back to the control system so as to adjust the rotation speed of the linear speed regulating mechanism 4 in real time, thereby maintaining the stability of the film tension; it helps to solve problems such as uneven tension, curling, and tensile deformation in traditional winding and unwinding equipment, and improve product quality and subsequent processing effects.

[0026] like Figures 1 to 3 As shown, the line speed adjustment mechanism 4 also includes: The hydraulic box 45 is fixedly mounted on the support base 1 and stores hydraulic oil to provide the necessary medium for the hydraulic system; The piston rod 46 is fixedly mounted at the bottom end of the bearing slider 44 and is sealed and slidably arranged in the hydraulic box 45; as an actuator of the hydraulic system, it converts hydraulic energy into mechanical energy to push or pull the bearing slider 44 and the pressure roller 5 to move; The hydraulic pump 47 is fixedly mounted on the support base 1 and is interconnected with the hydraulic box 45 to control the hydraulic strength inside the hydraulic box 45; it provides power for the hydraulic system and generates hydraulic pressure by extracting and compressing hydraulic oil; An oil inlet pipe 48 is connected to the hydraulic box 45 and is used to transport hydraulic oil; The hydraulic oil is transported to the hydraulic box 45 for storage through the oil inlet pipe 48; when it is necessary to adjust the pressure of the pressure roller 5 on the capacitor film, the hydraulic pump 47 starts to work; it extracts the hydraulic oil in the hydraulic box 45 and generates hydraulic pressure by compression; the generated hydraulic pressure is transmitted to the piston rod 46 through the hydraulic oil; by adjusting the working state of the hydraulic pump 47, the hydraulic strength inside the hydraulic box 45 can be controlled, so as to achieve precise adjustment of the thrust of the piston rod 46; the force of the piston rod will be transmitted to the pressure roller 5 through the bearing slider 44; when the pressure roller 5 has a tendency to move upward, it will increase the pressure on the capacitor film, thereby increasing the winding compactness; on the contrary, when the pressure roller 5 is not subjected to force or has a tendency to move downward, it will reduce the pressure on the capacitor film and reduce the winding compactness; the hydraulic part of the line speed adjustment mechanism 4 controls the pressure roller 5 through the delivery of hydraulic oil, the generation and adjustment of pressure, and the movement of the piston rod, thereby adjusting the winding compactness of the capacitor film roll; it helps to improve the stability and efficiency of the winding and unwinding operation, and ensure the quality of the capacitor film and the subsequent processing effect.

[0027] The method for adjusting the tension adjustment mechanism of the capacitor film reeling and unreeling of the present invention comprises: According to the conveying speed and required tension of the capacitor film, set the winding speed of the winding roller on the winding mechanism; Start the hydraulic pump, deliver the hydraulic oil to the hydraulic box through the oil inlet pipe, adjust the oil inlet volume and pressure of the hydraulic pump, make the hydraulic strength inside the hydraulic box reach the initial setting value, and make the pressure roller in the initial position; The capacitor film is rolled up by a winding roller to obtain a capacitor film roll, and the tension of the capacitor film is obtained in real time; According to the diameter growth of the capacitor film roll, the speed of the winding roller is adaptively adjusted to maintain a constant tension of the capacitor film; In response to the capacitor film tension exceeding a preset tension threshold, the oil intake and pressure of the hydraulic pump are reduced, the pressure of the pressure roller on the capacitor film is reduced, and the tension of the capacitor film is reduced; In response to the capacitor film tension being less than a preset tension threshold, the oil intake and pressure of the hydraulic pump are increased, the pressure of the pressure roller on the capacitor film is increased, and the tension of the capacitor film is increased; After the capacitor film is rolled up, the capacitor film roll and the winding roller are removed together.

[0028] The method can accurately control the tension of the film by acquiring the tension of the capacitor film in real time and adaptively adjusting the rotation speed of the winding roller and the pressure of the pressure roller according to the tension change; it is helpful to ensure the flatness and tightness of the film during the winding process and improve the product quality; the method realizes the automatic control of the winding and unwinding process through the coordinated work of components such as a hydraulic pump, a hydraulic box, a winding roller and a pressure roller; it not only improves the production efficiency, but also reduces the complexity and labor intensity of manual operation; the method can be flexibly adjusted according to parameters such as the material properties of the capacitor film, the conveying speed and the required tension, so it has strong adaptability; whether it is different types of capacitor films or different production requirements, the method can meet them; since the method adopts automatic control and real-time monitoring technology, it can timely discover and handle abnormal conditions in the winding process, such as excessive or insufficient tension; this timely fault handling helps to reduce the risk of equipment damage and production interruption, and improve the stability and reliability of the equipment.

[0029] The factors affecting the setting of the preset tension threshold include: Material properties of capacitor films: Capacitor films made of different materials have different elastic modulus, strength and toughness; these properties will directly affect the tension performance of the film during the winding process; therefore, when selecting the preset tension threshold, the material properties of the film must be fully considered to ensure that the tension is controlled within an appropriate range; Winding speed: The faster the winding speed, the greater the dynamic tension on the film; the winding speed needs to be considered when setting the preset tension threshold; Line speed: Changes in line speed will affect the tension performance of the film; therefore, when setting the preset tension threshold, the influence of line speed needs to be considered to ensure the stability and accuracy of tension control; Change in the diameter of the winding roller: As the winding process proceeds, the diameter of the winding roller will gradually increase; this will cause the tension of the film to change; in order to maintain a constant tension, the winding speed needs to be adaptively adjusted according to the change in the diameter of the winding roller; therefore, the setting of the preset tension threshold also needs to consider the impact of the change in the diameter of the winding roller; Pressure of the pressure roller: The pressure roller controls the tension of the film by applying pressure. The oil intake and pressure of the hydraulic pump determine the pressure of the pressure roller on the film. Therefore, when setting the preset tension threshold, the flexibility and accuracy of the pressure roller pressure adjustment need to be considered to ensure the accuracy of tension control. Production process requirements: Different production processes have different requirements for film tension; for example, some processes require the film to have a high degree of flatness and a tight winding structure, which requires the setting of the preset tension threshold to be more precise and stable.

[0030] In this step, by comprehensively considering various influencing factors, the preset tension threshold can be set more accurately, thereby achieving precise control of the tension of the capacitor film; it helps to ensure the flatness and tightness of the film during the winding process to meet production requirements; since multiple factors are taken into consideration, the setting of the preset tension threshold is more flexible and can adapt to different types of capacitor films, different production speeds and different production process requirements; this enhances the adaptability and flexibility of the system and improves production efficiency and product quality; precise tension control helps reduce the risk of equipment damage and production interruption caused by excessive or insufficient tension; at the same time, by optimizing the setting of the preset tension threshold, unnecessary material waste and energy consumption can be reduced, thereby reducing production costs; precise tension control and a stable production process help improve the quality of the capacitor film; this includes improving the flatness of the film, reducing defects such as wrinkles and bubbles, and ensuring that the winding structure of the film is tight and uniform.

[0031] The capacitor film winding and unwinding tension adjustment mechanism and adjustment method of the present invention are all installed, connected or set in common mechanical ways, and can be implemented as long as they can achieve their beneficial effects.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
