Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, and specifically to a transfer device for thin film production. Background Technology

[0002] In film production, stretching (orientation) and slitting (rewinding) are two crucial post-processing steps that directly determine the final physical properties, dimensional specifications, and quality of the film. The stretching process, performed by a stretching machine, aims to heat and stretch the melt-extruded and cooled sheet (called a "cast sheet"), aligning the polymer chains in a specific direction and significantly improving the film's properties. The slitting process, performed by a slitting machine, aims to precisely slit the stretched, and possibly surface-treated (e.g., corona treatment) master roll (large roll, wide-width film) into multiple smaller rolls according to the width and length (roll diameter or meters) required by the customer's order, and then rewind them into neat, appropriately tight, and defect-free finished rolls.

[0003] Generally, the entire factory space is divided into multiple independent production areas by multiple sets of walls. Each production area will house corresponding components and carry out corresponding production processes. For example, the stretching and slitting processes mentioned above are carried out in two separate production areas. The production area where the stretching process is located is defined as the stretching area, and the production area where the slitting process is located is defined as the slitting area.

[0004] Since a curing process is required after the film stretching process, a curing area is usually set up between the stretching area and the slitting area. After the rolls in the stretching area are made, they are usually transferred to the curing area for temporary storage for a period of time, and then transported to the slitting area for slitting and rewinding using the slitting machine in the slitting area. Figure 1 The diagram illustrates a material roll structure in the prior art, where a represents a steel core and b represents a multi-layered film wound on the steel core. Due to the long length and heavy overall weight of the material roll, a lifting device is generally provided in the curing area to lift the cured material roll and extend it to the slitting machine in the slitting area using a lifting telescopic arm, so that the material roll can be subsequently slitting and rewinding.

[0005] However, when using the aforementioned transfer method, due to the working characteristics of the lifting equipment, it is necessary not only to restrict the curing area and the slitting area to adjacent positions, but also to remove the partition wall between the curing area and the slitting area. This operation not only allows external insects, dust, and other foreign objects to enter the slitting area, interfering with the slitting and rewinding work, but also allows hot air from the curing area to flow into the slitting area. Since the slitting area requires a low working environment temperature, the heat carried by the hot air will also interfere with the slitting work. Furthermore, the slitting area needs sufficient lateral and longitudinal space to accommodate the lifting boom's range of motion. This increased space requires advance planning and significantly increases construction costs.

[0006] In view of the inconvenience caused by the above-mentioned transfer methods, we propose a transfer device for thin film production to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a transfer device for film production in order to solve the problems in the prior art. The design of this transfer device provides a transfer channel for the material roll, and the design of the push arm to apply an inclined thrust to the material roll not only reduces the frictional resistance between the steel core and the contact surface, but also provides horizontal driving force to achieve a stable conveying effect.

[0008] To solve the above problems, this utility model provides the following technical solution:

[0009] An adapter for thin film production, comprising:

[0010] The adapter bracket has a feeding end located in the curing zone and a discharging end located in the slitting zone;

[0011] The booster arm is movably mounted on the adapter bracket, and its actuator end is normally located below the working surface of the adapter bracket. In the working state, it can be flipped to a position above the feed end so that when the material coil is placed at the feed end, the actuator end of the booster arm abuts against the side of the steel coil core and applies an abutting force that can be decomposed into vertical and horizontal components to the steel coil core, so that the steel coil core has a tendency to roll towards the discharge end.

[0012] As a further embodiment of this utility model: the booster arm is generally L-shaped, with one end mounted on the first rotating shaft at the feed end and the other end constituting the execution end. A first drive source is movably arranged on the adapter bracket, and the execution end of the first drive source is provided with a first connecting arm for connecting with the first rotating shaft.

[0013] As a further embodiment of this utility model: a second rotating shaft is provided at the discharge end, and a bridging bridge plate is installed on the second rotating shaft. The bridging bridge plate can overlap the frame of the slitting machine as the second rotating shaft rotates to form a transition channel for rolling steel coil cores.

[0014] As a further embodiment of this utility model: a second drive source is movably disposed on the adapter bracket, and the execution end of the second drive source is provided with a second connecting arm for connecting with the second rotating shaft.

[0015] As a further embodiment of this utility model: the feed end is provided with a stop for blocking the steel coil core, and the side of the stop that contacts the steel coil core is arc-shaped.

[0016] As a further embodiment of this invention: the first driving source is configured as a cylinder or a hydraulic cylinder.

[0017] As a further embodiment of this invention, the second driving source is configured as a cylinder or a hydraulic cylinder.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By clearly defining functional areas at the feed and discharge ends of the transfer bracket, the transfer process of the steel coil core becomes clear and controllable. The movable setting of the booster arm and the position design of its actuator end can precisely apply inclined thrust, decomposing the force into vertical and horizontal components. This reduces the frictional resistance between the steel coil core and the contact surface while providing horizontal driving force, achieving efficient and labor-saving rolling conveying. Simultaneously, the pushing action of this booster arm can transform the stationary steel coil core into a moving state, resulting in a substantial change in the state of the steel coil core from "static" to "dynamic."

[0020] 2. Through the cooperation of the first rotating shaft and the first drive source, the swinging motion of the booster arm is automatically controlled, improving operational accuracy and efficiency. The first connecting arm, as a transmission intermediary, simplifies the power transmission path, making the movement of the booster arm more stable and reliable, suitable for high-intensity continuous operation, and reducing the need for manual intervention.

[0021] 3. The combination of the second rotating shaft and the bridging bridge plate forms an adjustable transition channel, which flexibly connects to the slitting machine frame through rotation, achieving seamless transfer of steel coil cores. This design solves the problem of mismatched height or position between equipment, reduces the risk of collisions during material transfer, and improves the continuity of the production line.

[0022] 4. The second drive source controls the rotation of the second rotating shaft through the second connecting arm, realizing the automated deployment and retraction of the bridge plate. This structure forms a collaborative system with the first drive source, ensuring bidirectional coordination during the transfer process, further reducing manual operation intensity and improving system response speed.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] like Figures 4-6As shown, an intermediate transfer system connects the curing area and the slitting area, enabling smooth and convenient transport of material rolls from the curing area to the slitting area. This transfer system provides excellent transport functionality, eliminating the need for sufficiently large lateral and longitudinal spaces in the slitting area, and also avoiding the requirement for the curing and slitting areas to be arranged adjacently. Specifically, the system includes the following:

[0034] (1) Adapter bracket 1, the two ends of the adapter bracket 1 are defined as feed end 101 and discharge end 102 respectively. Feed end 101 is placed in the curing area and discharge end 102 is placed in the slitting area. Feed end 101 is provided with a stop part 9, and one side of the stop part 9 is arc-shaped. In use, the material roll in the curing area can be lifted to the feed end 101 by the lifting equipment. At this time, the steel core a of the material roll will fall to the top of the feed end 101 and be blocked by the arc side of the stop part 9, so that the steel core a can be kept stable. Then the steel core a is rolled and conveyed to the discharge end 102, and finally conveyed to the slitting machine c for slitting and rewinding, thus completing the entire transfer work. It should be noted that the design length of this adapter bracket 1 can be adapted to the distance between the curing area and the cutting area, and this adapter bracket 1 serves to directly connect the two areas without forcing the two areas to be adjacent, thus adapting to the spatial layout of different types of factory areas.

[0035] (2) A booster arm 2 has a first rotating shaft 3 rotatably mounted at the feed end 101. The booster arm 2 is mounted on the first rotating shaft 3, and the rotation of the first rotating shaft 3 can drive the booster arm 2 to swing. Simultaneously, a first drive source 4 is mounted on the adapter bracket 1, and the execution end of the first drive source 4 is connected to a first connecting arm 5. The first connecting arm 5 is connected to the first rotating shaft 3. This connection layout can be configured by… Figure 4 The booster arm 2 has an L-shaped layout, with one end connected to the first rotating shaft 3 and the other end serving as the actuator. When the first drive source 4 retracts, the first connecting arm 5 drives the booster arm 2 to rotate clockwise around the first rotating shaft 3. When a coil is placed on top of the feed end 101, and the steel core a of the coil is within the movement path of the booster arm 2, the clockwise movement of the booster arm 2 applies an initial boosting force to the steel core a, causing the steel core a to change from a stationary state to a rolling state.

[0036] Furthermore, in this embodiment, the booster arm 2 has the following two designs for the boosting direction of the steel coil a:

[0037] (1) The direction of the push is horizontal: Under this design, when the execution end of the push arm 2 comes into contact with the steel core a, the direction of the force applied by the push arm 2 to the steel core a is horizontal, and this horizontal direction is from the feed end 101 to the discharge end 102.

[0038] (2) The booster direction is tilted, and the tilt direction is from the lower left to the upper right: This design layout can be achieved by... Figure 4 The state shown is represented by the fact that the actuating end of the push arm 2 abuts against the side of the steel coil core a. When the first drive source 4 is working, the push arm 2 in this state can generate a pushing force. This pushing force can be decomposed into two components: vertically upward and horizontally to the right. The horizontally to the right component can overcome the frictional resistance between the steel coil core a and the feed end 101, giving the steel coil core a a tendency to roll to the right. The vertically upward component will partially offset the weight of the coil, thereby reducing the support force of the feed end 101 on the coil.

[0039] Example 2:

[0040] To enhance protection of the slitting area, the inlet and outlet near the discharge end 102 are controlled by a roller shutter d. When the material roll has not reached the discharge end 102, the roller shutter d is closed, effectively preventing insects from entering the slitting area; when the material roll reaches the discharge end 102, the roller shutter d is open, allowing it to be transferred to the frame of the slitting machine c via the discharge end 102.

[0041] In the design of the roller shutter door d, if it needs to be combined with the above-mentioned transfer system, then in this embodiment, a second rotating shaft 6 is rotatably provided at the feeding end 101. A crossover bridge plate 15 is installed on the second rotating shaft 6. The rotation of the second rotating shaft 6 can drive the crossover bridge plate 15 to move accordingly. A second driving source 7 is movably provided on the transfer bracket 1. A second connecting arm 8 is provided at the execution end of the second driving source 7. The second connecting arm 8 is connected to the second rotating shaft 6. Therefore, by starting the second driving source 7, the crossover bridge plate 15 can be driven to perform corresponding swinging movements.

[0042] Figure 4 In the indicated state, when the second drive source 7 retracts, it can drive the bridging plate 15 to rotate clockwise until the bridging plate 15 rotates to a horizontal position and overlaps the frame of the slitting machine c. This state can be achieved by... Figure 5 To represent this. At this time, Figure 4 The material roll in this state can roll horizontally to the right sequentially from the feed end 101, the discharge end 102, and the bridging plate 15 onto the slitting machine c. When Figure 5After the slitting machine c completes the slitting and rewinding process, only the steel coil core a remains. At this point, the roller shutter d can be opened to detach the steel coil core a from the slitting machine c and transfer it to the middle position of the transfer bracket 1 via the bridging bridge 15. Then, the roller shutter d is closed, and the steel coil core a is lifted upwards using lifting equipment. This state can be achieved by... Figure 6 To represent it.

[0043] The design of the first driving source 4 and the second driving source 7 in Embodiment 1 and Embodiment 2 can be any linear driving component in the prior art, such as a cylinder or a hydraulic cylinder. To avoid cumbersome writing, this article will not elaborate further.

[0044] Example 3:

[0045] In the slitting area, the slitting process is carried out by the slitting machine C. Its purpose is to accurately slit the stretched and online inspected roll (master roll) into multiple smaller rolls according to the width and length (roll diameter or meters) required by the customer's order, and then rewind them into finished rolls with a neat appearance, appropriate tightness, and no defects.

[0046] Furthermore, some material rolls will undergo surface treatment (such as corona treatment) on their outer side. Depending on customer requirements, the corona side after slitting and rewinding needs to become the outer or inner side of the finished roll. Therefore, before lifting and placing the material roll at the feed end 101, the roll exit direction needs to be determined. Only after the exit direction is determined can the roll be transferred to the slitting machine c, where it will be slitted and rewound according to predetermined requirements. The corona side of the rewound finished roll will become the required outer or inner side.

[0047] Therefore, the difference between this embodiment and any of the above embodiments is that this embodiment adds a set of rotating components, such as... Figures 2-3 As shown, the rotating component is located on the side of the feed end 101. The rotating component is used to support the material roll and can drive the material roll to rotate in the horizontal direction, so that the output direction of the material roll can be easily adjusted so that the corona side on it will become the designated outer or inner side in the subsequent rewinding process.

[0048] Specifically, the rotating assembly includes a support base 10 mounted on the ground. The support base 10 is designed to rotate, and a roll-up platform 11 is mounted on top of the support base 10. The top surface of the roll-up platform 11 is arc-shaped to accommodate the material roll. A cushioning layer 14 can be fixedly mounted on this top surface to cushion and protect the material roll during connection. Due to the rotational design of the support base 10, the roll-up platform 11 can drive the material roll to rotate horizontally. Alternatively, the support base 10 can be fixed, with the connection between the roll-up platform 11 and the top of the support base 10 being rotational. Furthermore, the support base 10 can be a telescopic structure to allow for height adjustment of the roll-up platform 11.

[0049] Under normal circumstances, the tray platform 11 is Figure 3 As shown in the layout, the lifting equipment places the material roll on the roll support platform 11. If the roll exit direction on the roll support platform 11 in this state is opposite to the required direction, the roll support platform 11 can be rotated 180 degrees to adjust the roll exit direction and meet the position requirements of the corona side during subsequent slitting and rewinding by the slitting machine c. Figure 2 This can be represented as a state where the rotation angle of the tray platform 11 is 90 degrees during the process of rotating 180 degrees.

[0050] To ensure smooth and stable rotation of the coil support platform 11 while supporting the coil, this embodiment also includes an annular ground rail 12. The annular ground rail 12 is located on the ground next to the feed end 101, and the rotation axis of the support base 10 coincides with the axis of the annular ground rail 12. At the same time, several sets of auxiliary wheels 13 are provided at the bottom of the coil support platform 11. The auxiliary wheels 13 are located in the track of the annular ground rail 12. During the rotation of the coil support platform 11, the auxiliary wheels 13 will travel in the track of the annular ground rail 12, playing a role in assisting support and assisting rotation.

[0051] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
