Description

Technical Field

[0001] This utility model relates to an unwinding device, and more particularly to an unwinding device for photosensitive film production. Background Technology

[0002] In the production process of photosensitive film, the unwinding device is usually set up in conjunction with related processing equipment such as photosensitive film coating and lamination. The unwinding device continuously and evenly unwinds the film material in the film roll to ensure that subsequent processing can proceed smoothly. An efficient unwinding device is crucial for improving the production efficiency and product quality of photosensitive film.

[0003] In existing photosensitive film production, the unwinding device typically consists of a film unwinding roller and a film guiding component. During the unwinding, loading, and installation steps, the unwinding operations usually require manual labor or the use of auxiliary equipment. The operator moves the film roll from the storage area to the unwinding machine, lifts it to align it with the axis, pushes it into the axis of the unwinding roller to ensure smooth installation, and secures it with clips or fasteners to prevent loosening or falling off during unwinding. The unwinding machine is then started, and the operator checks whether the film roll unfolds smoothly and adjusts the unwinding speed as needed to ensure uniform unfolding of the substrate. Throughout the process, the operator... Personnel need to continuously monitor the unwinding process and eliminate any abnormalities. However, manual operation has several significant drawbacks: First, handling and lifting the film rolls requires considerable physical strength, easily leading to operator fatigue and increasing the risk of workplace injuries over extended periods. Second, manual alignment and fixing of the film rolls is prone to errors, resulting in inaccurate installation and affecting the quality of subsequent processes. Furthermore, manual operation is time-consuming, especially when changing film rolls, requiring multiple manual adjustments and involving a cumbersome process that reduces production efficiency. Additionally, the operation carries higher safety risks, with operators susceptible to injury from falling or pinched objects. Finally, varying skill levels and experience among operators result in inconsistent film roll installation quality, affecting production consistency and stability.

[0004] Therefore, it is necessary to significantly improve production efficiency and product quality by improving the structure and process of unwinding the film roll. Utility Model Content

[0005] In order to overcome the shortcomings of existing unwinding devices, which have a relatively simple structure and require manual operation for changing and installing film rolls, resulting in cumbersome procedures and a series of drawbacks that may affect production efficiency and quality, the purpose of this utility model is to provide an improved film roll unwinding device for photosensitive film production that significantly improves production efficiency and product quality by improving the structure and process of film roll unwinding.

[0006] The technical solution is: a film roll unwinding device for photosensitive film production, comprising a base, a control cabinet, a fixed plate, a first transfer roller, a second transfer roller, a mounting plate, a third transfer roller, a rotating telescopic component, a rotating telescopic rod, a locking block, and a guide rail. The control cabinet is located on the front side of the base, and a control panel is mounted on the control cabinet. Fixed plates are located on both the front and rear sides of the right side of the base. The first and second transfer rollers are rotatably mounted on the upper and lower parts of the fixed plates, respectively. Mounting plates are located on the left side of the upper part of each fixed plate, and rotating telescopic components are mounted on the left side of each mounting plate. Each rotating telescopic component is equipped with a rotating telescopic rod. The telescopic component has two sets of cooperating power systems, which drive the telescopic rod to extend and rotate. The two telescopic components are symmetrically arranged front and back. Each end of the telescopic rod is equipped with a locking block, which rotates and moves back and forth with the telescopic rod. A material transfer roller is rotatably installed between the lower parts of the mounting plate. Two horizontal guide rails are arranged in parallel in the lower part of the base. An upwind mechanism is installed on the guide rails, which moves and lifts the film material to the area between the two locking blocks for upwinding.

[0007] In a preferred embodiment of this utility model, the winding mechanism includes a loading trolley, a hydraulic rod, a power wheel, a lifting plate, a chute, and a bracket. The loading trolley moves on the guide rail via the power wheel mounted on its lower part. The loading trolley is equipped with a drive mechanism that drives the power wheel to rotate, thereby enabling the loading trolley to move left and right on the guide rail. The loading trolley is equipped with a hydraulic component, on which a hydraulic rod is mounted. A lifting plate is mounted on the top of the hydraulic rod. A chute is opened on the lifting plate, and brackets are symmetrically and slidably mounted in the chute. A slot is provided on the upper part of the bracket, and the film roll is supported by two brackets.

[0008] In a preferred embodiment of this utility model, it further includes a rotating shaft, a swing arm, an electric cylinder, and a sensor. The rotating shaft is rotatably mounted on the upper part of the mounting plate. A motor is mounted on one end of the rotating shaft. Swing arms are mounted on both the front and rear sides of the rotating shaft. An electric cylinder is mounted on each swing arm. The two electric cylinders are symmetrically arranged front and rear. The moving rods of the electric cylinders pass through the swing arms on the same side, and a sensor is mounted on the moving rods of the electric cylinders. The electric cylinder drives the sensor to move back and forth, and the motor drives the rotating shaft to rotate at a certain angle, thereby causing the swing arm to swing up or down.

[0009] In a preferred embodiment of the present invention, a heating box and a feeding rod are also included. The heating box is provided between the upper and lower parts of the fixed plate. The heating box has a heating cavity inside. The upper and lower sides of the heating box have notches that allow the film material to pass through. The feeding rod is rotatably provided at the notches on the upper and lower sides of the heating box. The heating box is equipped with a heating element.

[0010] In a preferred embodiment of the present invention, a support base is also included. The inner side of the mounting plate is provided with a support base, and the support base slides in contact with the rotating telescopic rod on the same side.

[0011] Compared with the prior art, the present invention has the following advantages: By setting a rotating telescopic component for clamping the film roll, and cooperating with the feeding trolley for material transfer, the worker only needs to place the film roll on the feeding trolley, and the unwinding machine can automatically complete the lifting, positioning and installation steps, which greatly simplifies the operation process, improves work efficiency, reduces manual intervention, reduces labor intensity, and also reduces the possibility of human error, further improving the stability and reliability of the overall production.

[0012] The positioning mechanism of this invention determines the position of the film roll within the unwinding device by contacting the edge of the film roll with a sensor after the film roll is installed. It then feeds back the position information to the control system of the rotating telescopic component, thereby causing the two rotating telescopic components to synchronously adjust their respective extension lengths to adjust the position of the film roll. This eliminates the errors that are easily caused by traditional unwinding devices and manual adjustment methods, and improves the alignment accuracy and processing efficiency of subsequent operations.

[0013] This invention incorporates a heating device along the transport path of the film material after unwinding. This heating treatment effectively eliminates internal stress in the film material, thereby improving its stability and processing performance, ensuring smooth subsequent processing and the final quality of the product. The heating device can uniformly transfer heat to the film material, relaxing its molecular structure and eliminating internal stress concentration during winding and storage. This prevents problems such as film material deformation and cracking, improving not only the film material's toughness but also its adaptability to subsequent processing steps.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: A film roll unwinding device for photosensitive film production, such as... Figure 1-5 As shown, the device includes a base 1, a control cabinet 2, a fixing plate 3, a first transfer roller 31, a second transfer roller 32, a mounting plate 4, a third transfer roller 41, a rotating telescopic component 5, a rotating telescopic rod 51, a locking block 52, and a guide rail 6. The base 1 serves as the foundation support for the entire device, stably bearing all components. The control cabinet 2, located at the front, is equipped with a control panel on its upper part, facilitating precise control of the device by operators. The integrated electrical system within the control cabinet 2 provides a stable power supply and control signal transmission for the entire device, ensuring its efficient operation.

[0022] The base 1 has two fixing plates 3 on the front and rear sides of the right side. These two fixing plates 3 not only provide the installation position for the transfer rollers, but also ensure the stability of the transfer process. Between the upper and lower parts of the fixing plates 3, transfer roller 1 31 and transfer roller 2 32 are respectively rotatably installed. They are connected to the fixing plates 3 through bearings and can rotate flexibly, thereby guiding the film material to be transferred smoothly. This design allows the film material to maintain a certain tension and stability during the transfer process, avoiding film material damage or wrinkles caused by uneven tension or poor transfer.

[0023] Mounting plates 4 are provided on the upper left side of the fixing plate 3. The mounting plates 4 serve as the carriers for the rotating telescopic components 5, providing them with a stable installation environment. Rotating telescopic components 5 are installed on the left side of the mounting plates 4. These rotating telescopic components 5 integrate two sets of mutually cooperating power systems, such as a combination of a motor and a reducer. Through a precision transmission mechanism, they drive the rotating telescopic rod 51 to perform telescopic and rotational movements. This design allows the clamping block 52 to rotate precisely and move back and forth with the rotating telescopic rod 51, thereby achieving precise clamping and unwinding operations of the film roll.

[0024] The two rotating telescopic components 5 are symmetrically arranged front and back. This layout not only ensures the balance of clamping force but also improves the overall stability of the device. Each end of the rotating telescopic rod 51 is equipped with a locking block 52, made of wear-resistant material, which provides excellent clamping effect and durability. Driven by the rotating telescopic components 5, the locking block 52 can tightly clamp the film roll and achieve unwinding through rotation. Simultaneously, the forward and backward movement of the locking block 52 facilitates the replacement and installation of the film roll, improving production efficiency.

[0025] A rotatable transfer roller 3 41 is mounted on the lower part of the mounting plate 4. It, together with transfer roller 1 31 and transfer roller 2 32, forms the film material transmission path. After passing under transfer roller 3 41, the film material is transmitted to the right and then passes over the upper part of transfer roller 1 31 to the upper right, before being transmitted from under transfer roller 2 32. This transmission path design not only ensures smooth transmission of the film material, but also provides tension and guidance to the film material through the rotation of the transfer rollers, preventing the film material from shifting or slipping during transmission.

[0026] Two horizontal guide rails 6 are arranged parallel to each other in the lower part of the base 1, providing stable track support for the movement of the winding mechanism. The winding mechanism is equipped on the guide rails 6. This mechanism, driven by a motor and a transmission mechanism, can move horizontally along the guide rails 6 and lift the film material into the area between the two clamping blocks 52 for winding. This design not only realizes the automated winding process of the film roll, but also improves the winding efficiency and accuracy, avoiding errors or safety hazards caused by manual operation.

[0027] Among them, such as Figure 2 and Figure 4 As shown, the winding mechanism includes a loading trolley 61, a hydraulic rod 611, a power wheel 62, a lifting plate 63, a slide 631, and a bracket 64. The loading trolley 61 is the core moving component of the entire winding mechanism. Through the power wheel 62 installed at its lower part, it closely cooperates with the guide rail 6, realizing flexible movement on the guide rail 6. This design enables the loading trolley 61 to be quickly and accurately positioned to the designated position as needed, providing stable support and precise positioning basis for subsequent film roll winding operations.

[0028] The loading trolley 61 is equipped with a drive mechanism, which is connected to the power wheel 62 through a precision transmission device. The drive wheel 62 is rotated, which in turn drives the loading trolley 61 to move smoothly in the left and right directions on the guide rail 6. This design not only improves the flexibility of the winding mechanism, but also ensures the stability and accuracy during the movement, avoiding film roll offset or damage caused by unstable movement.

[0029] Inside the loading trolley 61, there is also a hydraulic component. This component provides a stable driving force to the hydraulic rod 611 through the hydraulic transmission principle. As a key component of the lifting mechanism, the top of the hydraulic rod 611 is closely connected to the lifting plate 63. Driven by the hydraulic component, the hydraulic rod 611 can drive the lifting plate 63 to achieve vertical lifting movement. This design allows the lifting plate 63 to be flexibly adjusted according to the height and position of the film roll, providing precise lifting control for the film roll winding operation.

[0030] The lifting plate 63 has a sliding groove 631, which provides a stable track support for the sliding of the bracket 64. The bracket 64 is symmetrically and slidably installed in the sliding groove 631. This layout not only ensures the stability of the bracket 64 during the sliding process, but also improves the clamping force and adaptability of the winding mechanism to film rolls of different sizes. The upper part of the bracket 64 has a slot, which allows the bracket 64 to tightly clamp the film roll and avoid the film roll from loosening or shifting during transportation or winding. Through the synergistic effect of the two brackets 64, the film roll can be stably lifted and accurately placed in the designated position, providing strong support for subsequent processing operations.

[0031] The operation process of the film roll unwinding device for photosensitive film production is as follows: First, the film roll is placed on the upper winding mechanism on the guide rail 6, and driven by the motor, it moves horizontally along the guide rail 6 to the position below the two clamping blocks 52. Then, the upper winding mechanism lifts the film material upward to the same center line as the clamping blocks. The rotating telescopic component 5 is activated, and its internal power system drives the rotating telescopic rod 51 to extend and retract, so that the clamping blocks 52 accurately clamp the film roll. Then, one end of the film material is manually pulled out for film laying. The film material passes under the third transfer roller 41, and is guided by the first transfer roller 31 and the second transfer roller 32. The third transfer roller 41, the first transfer roller 31, and the second transfer roller 32 begin to rotate, smoothly and tautly conveying the film material. Finally, driven by the rotating telescopic component 5, the clamping blocks 52 rotate to realize the unwinding operation. At the same time, the upper winding mechanism can continue to move to lift new film material for upper winding. The entire processing step is completed automatically, efficiently and accurately.

[0032] Example 2: Based on Example 1, such as Figure 1-3As shown, it also includes a rotating shaft 7, a swing arm 71, an electric cylinder 72, and a sensor 73. The upper part of the mounting plate 4 is rotatably equipped with a rotating shaft 7. One end of the rotating shaft 7 is equipped with a motor, which drives the rotating shaft 7 to rotate. Swing arms 71 are fixed on both the front and rear sides of the rotating shaft 7. The ends of the swing arms 71 extend towards the rotating telescopic member 5. Each swing arm 71 is equipped with an electric cylinder 72. The two electric cylinders 72 are symmetrically arranged front and rear. The movable rods of the electric cylinders 72 pass through the swing arms 71 on the same side, and sensors 73 are installed on the movable rods of the electric cylinders 72. The electric cylinders 72 drive the sensors 73 to move back and forth. The motor drives the rotating shaft 7 to rotate a certain angle, thereby driving the swing arms 71 to swing up or down. Simultaneously, the electric cylinders 72 and sensors 73 on the swing arms 71 move along the arc path during the swing.

[0033] Initially, the drive rods of the electric cylinder 72 are in the retracted state. When the swing arm 71 swings downward, the sensor 73 moves along the arc to the outer area of ​​the front and rear sides of the film roll inside the clamping block 52. At this time, the sensor 73 extends with the drive rod of the electric cylinder 72, and the two sensors 73 on the front and rear sides will contact the front and rear sides of the film roll respectively. The two sensors 73 detect whether the film roll is in the relatively centered position of the device, and then feed back the signal to the two rotating telescopic members 5 to control the position of the film roll. By the sensor 73 contacting the edge of the film roll, the position of the film roll in the unwinding device is determined, and the position information is fed back to the control system of the rotating telescopic members 5. Then, the two rotating telescopic members 5 synchronously adjust their respective extension lengths to adjust the position of the film roll, eliminating the errors that are easy to occur in traditional unwinding devices that require manual adjustment, and improving the alignment accuracy and processing efficiency of subsequent operations.

[0034] In addition, such as Figure 1 and Figure 5 As shown, it also includes a heating box 8 and a feed rod 81. The heating box 8 is located between the upper parts of the fixing plate 3. The heating box 8 has a heating cavity inside, which is used to heat the film material passing through to eliminate its internal stress. The heating box 8 has notches on the upper and lower sides to allow the film material to pass through, ensuring that the film material can pass through smoothly. After the film material is unwound, it is transported to the right and will pass through the heating box 8 from top to bottom. The feed rod 81 is rotatably provided at the notches of the heating box 8 to guide the film material in and out and assist its smooth movement. The heating box 8 is also equipped with heating elements, such as heating rods or heating wires, which generate heat to be evenly transferred to the film material, so that it is heated evenly, thereby achieving the ideal heating effect, effectively eliminating the internal stress generated in the film material during processing, improving the stability of the film material and the quality of subsequent processing.

[0035] In a preferred embodiment: such as Figure 2 and Figure 3As shown, it also includes support seats 53. Support seats 53 are provided on the inner side of the mounting plate 4. These support seats 53 slide in contact with the rotating telescopic rod 51 on the same side, which not only provides stable support for the rotating telescopic rod 51, but also ensures its smoothness and accuracy during the telescopic process, thereby improving the structural strength and reliability of the entire device. Through the precise positioning and support of the support seats 53, the rotating telescopic rod 51 can more effectively disperse the pressure when subjected to external force, avoid deformation or damage caused by single-point force, and thus extend the service life of the device.

[0036] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
