Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a multi-station laminating machine with adjustable pressure. Background Technology

[0002] In the material processing of industries such as electronics, packaging, and printing, laminating machines are key equipment for achieving precise lamination of multi-layer materials. The unwinding and positioning accuracy of the upper release film directly affects the quality stability of the lamination process. The upper release film is usually fixed to the unwinding shaft by locking the hand-operated expansion shaft. During the fixing process, the position of the film roll needs to be manually observed and adjusted to ensure that it is in the middle position of the unwinding shaft. Because it relies on the operator's experience and visual judgment, it is easy to have large centering errors due to individual differences, which in turn causes the release film to run off-center and have uneven tension, resulting in quality problems such as lamination misalignment, bubbles, and wrinkles. Manual adjustment is time-consuming and reduces production efficiency. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1 Reference Figures 1-5 and Figure 8 This is the first embodiment of the present invention. This embodiment provides a pressure-adjustable multi-station laminating machine. The pressure-adjustable multi-station laminating machine includes a main component 1, including a frame 11. A feeding shaft 12 is provided on one side of the frame 11. A laminating mechanism, a receiving mechanism, and a driving mechanism are also provided on the frame 11. A driving mechanism is also provided on one side of the feeding shaft 12. The release film 3 is fixed in the middle position of the feeding shaft 12. The driving mechanism drives the feeding shaft 12 to rotate, thereby completing the unwinding of the release film 3. The laminating machine is a material composite equipment with precise pressure adjustment function and multiple independent laminating units. It is mainly used for efficient and precise lamination of multi-layer materials, adaptable to the production of materials with different characteristics and multiple specifications of products. The pressure of the laminating mechanism can be freely set according to the material characteristics. It supports independent adjustment of single-point or zone pressure to avoid damage to thin and brittle materials or poor bonding of adhesive materials, and ensures consistent composite quality. The equipment integrates 3 independent laminating units. Each station can operate synchronously or perform different laminating processes. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] Mounting component 2, mounted on feeding shaft 12, includes centering component 21, which is used to center release film 3.

[0031] The centering component 21 includes a rotating shaft 211 connected to the feeding shaft 12 by a bearing. A rotating sleeve 212 is fitted over the rotating shaft 211. A first spiral groove 211-1 is provided on the rotating shaft 211. A first slider 213 is fixed inside the rotating sleeve 212. The first slider 213 slides in the first spiral groove 211-1. When the rotation of the rotating sleeve 212 is restricted, the rotating sleeve 212 will slide on the rotating shaft 211. When the rotating sleeve 212 can rotate, the rotating sleeve 212 can rotate around the rotating shaft 211.

[0032] The rotating sleeve 212 is covered with a movable sleeve 214. A movable block 215 is fixed on the movable sleeve 214. A stop block 216 is slidably arranged inside the movable block 215. A spring 217 is fixed on one side of the stop block 216. The other end of the spring 217 is fixed inside the movable block 215. A movable groove 12-1 corresponding to the movable block 215 is opened on the feeding shaft 12.

[0033] Spring 217 causes stop 216 to protrude from the end face of feed shaft 12. The end face of stop 216 can contact the end face of sleeve 31 in release film 3, thereby restricting the position of release film 3 on feed shaft 12.

[0034] There are two rotating sleeves 212, two movable sleeves 214, and two movable blocks 215. There are two stop blocks 216. One of the stop blocks 216 in the movable block 215 is slidably arranged and located near the insertion end of the feeding shaft 12. The sliding arrangement of the stop block 216 avoids obstructing the insertion of the release film 3. The other stop block 216 in the movable block 215 is fixed inside the movable block 215. By changing the position of the two stop blocks 216, the sleeve 31 inside the release film 3 can be restricted to the center position of the feeding shaft 12. Two first spiral grooves 211-1 are opened on the rotating shaft 211 and rotate in opposite directions. When the rotating shaft 211 rotates, it can simultaneously drive the two stop blocks 216 to move closer or further away from each other.

[0035] A triangular block 219 is slidably disposed inside the movable sleeve 214. A return spring is fixed on one side of the triangular block 219. Multiple corresponding triangular slots 212-1 are opened inside the rotating sleeve 212. The return spring ensures that the triangular block 219 can engage with the triangular slots 212-1. In the initial state, the two stops 216 are farthest apart. At this time, the stops 216, which are slidably set inside the moving block 215, are completely inside the moving block 215 and will not affect the installation of the release film 3. After the release film 3 is placed in the middle position of the feeding shaft 12, the rotating shaft 211 is rotated. The first slider 213 slides in the first spiral groove 211-1, and the triangular block 219 engages with the triangular groove 212-1, so that the moving sleeve 214 and the rotating sleeve 212 form a whole. At this time, the two moving sleeves 214 can slide in the moving groove 12-1, thereby driving the two stops 216 to move closer to each other and completing the centering of the release film 3.

[0036] After both stops 216 are in contact with the release film 3, the movable sleeve 214 can no longer move. However, the rotating shaft 211 is still rotating. With the cooperation of the triangular block 219 and the triangular groove 212-1, the rotating sleeve 212 will rotate on its own axis instead of driving the movable sleeve 214 to continue moving.

[0037] Example 2 Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the stop block 216 has an inclined groove 216-1, and the inner wall of the moving groove 12-1 has an inclined block 218 fixed thereon. The moving block 215 has a through groove corresponding to the inclined block 218. In the initial state, the two stop blocks 216 are farthest apart. At this time, the moving block 215 is located at the end of the moving groove 12-1 and fits together. The inclined block 218 is engaged with the inclined groove 216-1, so that the spring 217 is compressed. The stop block 216 is completely located in the moving block 215 and will not hinder the installation of the release film 3. During alignment, the moving block 215 moves gradually, and the inclined block 218 gradually separates from the inclined groove 216-1. When the two are completely separated, the spring 217 returns to its original position, so that the stop block 216 protrudes from the surface of the unwinding shaft 12. The thickness of the protruding part is less than the thickness of the sleeve 31 of the release film 3, thereby avoiding affecting the unwinding of the release film 3.

[0039] During reset, the inclined block 218 will engage with the inclined groove 216-1 again, causing the stop block 216 to retract into the moving block 215, thus avoiding affecting the next installation.

[0040] Specifically, the mounting assembly 2 also includes an expansion member 22. A chamber 12-2 is provided on the feeding shaft 12, in which the expansion member 22 is located. The expansion member 22 is used to tighten the sleeve 31 of the release film 3.

[0041] The expansion component 22 includes a rotating ring 221 connected to the rotating shaft 211 by a bearing. A rotating disk 222 is fixed on the rotating ring 221. An arc-shaped groove 222-1 is opened on the rotating disk 222. A cylinder 223 is slidably arranged in the arc-shaped groove 222-1. Movable plates 224 are fixed on both sides of the cylinder 223. An arc-shaped plate 225 is fixed on one side of the movable plate 224.

[0042] In the initial state, the cylinder 223 is located in the arc groove 222-1, closest to the center of the rotating shaft 211. At this time, the arc plate 225 is in a contracted state, which does not affect the installation of the release film 3.

[0043] Specifically, there are four arc-shaped plates 225, and the feeding shaft 12 has a through groove corresponding to the moving plate 224. The rotating disk 222 is in contact with the inner wall of the chamber 12-2, and a friction block is fixed on the outer edge of the rotating disk 222. The rotating disk 222 will not rotate without a large external force.

[0044] When the rotating ring 221 drives the rotating disk 222 to rotate, the cylinder 223 slides in the arc groove 222-1. Since the moving plate 224 can only move horizontally, it drives the arc plate 225 to move outward and gradually fits tightly against the inner wall of the sleeve 31 of the release film 3. A friction block is fixed on the arc plate 225 to increase the friction between the arc plate 225 and the inner wall of the sleeve 31, thereby completing the expansion and tightening of the inner wall of the sleeve 31.

[0045] Specifically, the mounting component 2 also includes a trigger 23 located within the feeding shaft 12, which is used to trigger the tightening process after alignment is completed.

[0046] The trigger 23 includes a trigger block 231 slidably disposed within the stop block 216. A translation plate 232 is also slidably disposed inside the stop block 216. Both the translation plate 232 and the trigger block 231 have inclined surfaces, and the inclined surfaces of the two are in contact with each other. An extension plate is fixed on the translation plate 232, and a return spring is also fixed on one side of the extension plate for resetting the translation plate 232 and the trigger block 231. A protrusion is provided on the trigger block 231, and a groove corresponding to the protrusion is opened on the stop block 216 to limit the movement range of the trigger block 231 and ensure that the trigger block 231 will not separate from the stop block 216.

[0047] In the initial state, the ordinary spring causes the translation plate 232 to be in the direction close to the trigger block 231. The inclined surface of the translation plate 232 applies pressure to the inclined surface of the trigger block 231, causing the end face of the trigger block 231 to protrude from the end face of the stop block 216. When the alignment is about to be completed, the sleeve 31 will gradually apply pressure to the protruding trigger block 231, causing the trigger block 231 to move, thereby driving the translation plate 232 to move away from the trigger block 231.

[0048] Example 3 Reference Figures 5-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, a small rotating shaft 233 is connected to the bearing inside the feeding shaft 12. A rotating plate 234 is fixed on the small rotating shaft 233. A torsion spring 235 is sleeved on the small rotating shaft 233. The two ends of the torsion spring 235 are fixed to the small rotating shaft 233 and the inner wall of the chamber 12-2. One side of the translation plate 232 can contact the rotating plate 234. The torsion spring 235 is used to maintain the initial rotation angle of the small rotating shaft 233 and the rotating plate 234. When the translation plate 232 moves away from the trigger block 231, one end of the translation plate 232 will first contact the rotating plate 234, thereby driving the rotating plate 234 to rotate, thus causing the small rotating shaft 233 to rotate.

[0050] The rotating plate 234 is relatively long, which ensures that it can be aligned with sleeves 31 of different widths. However, the length of the rotating plate 234 does not cover the initial position of the movable sleeve 214, ensuring that even if the translation plate 232 moves when the movable sleeve 214 is in its initial position, it will not come into contact with the rotating plate 234.

[0051] Specifically, a lifting sleeve 236 is fitted on the small rotating shaft 233, and a second spiral groove 233-1 is opened on the small rotating shaft 233. A second slider 237 is fixed inside the lifting sleeve 236 and slides in the second spiral groove 233-1. A limiting groove is opened on the lifting sleeve 236, and a limiting block is fixed on the inner wall of the chamber 12-2. Through the cooperation of the limiting groove and the fiber block, the rotation of the lifting sleeve 236 is restricted, and it can only move up and down along the small rotating shaft 233.

[0052] When the small rotating shaft 233 rotates, the lifting sleeve 236 will move upward under the combined action of the second slider 237 and the second spiral groove 233-1.

[0053] Specifically, a lifting ring 238 is slidably mounted on the rotating shaft 211. A protrusion is fixed on the lifting ring 238, and a groove corresponding to the protrusion is opened on the rotating shaft 211. Through the cooperation of the protrusion and the groove, the lifting ring 238 can slide on the rotating shaft 211, but the two still maintain a unified rotation.

[0054] A locking block 239 is fixed on the lifting ring 238, and a locking groove 221-1 is opened in the rotating ring 221. There are multiple locking grooves 221-1 and two locking blocks 239. In the initial state, when the small rotating shaft 233 is not rotating, the lifting ring 238 is in the lowest position. At this time, the locking block 239 is separated from the locking groove 221-1. When the small rotating shaft 233 rotates, the lifting ring 238 moves upward, and the locking block 239 engages with the locking groove 221-1. Then, the rotation of the rotating shaft 211 can drive the rotating ring 221 to rotate, and finally drive the rotating disk 222 to rotate, thus triggering the tightening.

[0055] Specifically, a lifting column 2310 is slidably disposed inside the lifting ring 238. The lifting column 2310 is fixed on the lifting sleeve 236 and the two are fixed together by a connecting rod. The lifting column 2310 has a T-shaped cross section. An annular groove is provided inside the lifting ring 238, and the lifting column 2310 slides in it, so as not to hinder the rotation of the lifting ring 238.

[0056] When the lifting sleeve 236 moves upward, it will drive the lifting column 2310 to move upward, which in turn will move the lifting ring 238 upward, causing the locking block 239 to engage with the locking groove 221-1, thus triggering the tightening.

[0057] Specifically, one end of the rotating shaft 211 extends to the outside of the feeding shaft 12. A handle 2110 is fixed on the rotating shaft 211. A threaded post 2111 is threadedly connected to the feeding shaft 12. The handle 2110 is used to drive the rotating shaft 211 to rotate. The threaded post 2111 is used to lock the rotation angle of the handle 2110. The feeding shaft 12 has a threaded groove that extends through both ends of the feeding shaft 12 and is connected by threads. When the threaded post 2111 is rotated, the end face of the threaded post 2111 will gradually fit against the end face of the feeding shaft 12. Then, under the action of friction, the rotation of the handle 2110 can be restricted, thereby restricting the rotation of the feeding shaft 12, thus locking the position of the arc plate 225 and ensuring that the release film 3 is accurately and stably installed.

[0058] In the initial state of use, the two stops 216 are at their farthest distance. At this time, the stops 216, which are slidably set inside the moving block 215, are completely inside the moving block 215 and will not affect the installation of the release film 3. After the release film 3 is placed in the middle position of the feeding shaft 12, the rotating shaft 211 is rotated. The first slider 213 slides in the first spiral groove 211-1, and the triangular block 219 engages with the triangular groove 212-1, so that the moving sleeve 214 and the rotating sleeve 212 form a whole. At this time, the two moving sleeves 214 can slide in the moving groove 12-1, thereby driving the two stops 216 to move closer to each other, completing the centering of the release film 3, ensuring that the release film 3 is located in the middle position of the feeding shaft 12, and avoiding problems such as deviation and uneven tension caused by positional offset.

[0059] After both stops 216 are in contact with the release film 3, the movable sleeve 214 can no longer move. However, the rotating shaft 211 is still rotating. With the cooperation of the triangular block 219 and the triangular groove 212-1, the rotating sleeve 212 will rotate on its own axis instead of driving the movable sleeve 214 to continue moving.

[0060] As the alignment is about to be completed, the sleeve 31 will gradually apply pressure to the protruding trigger block 231, causing the trigger block 231 to move. This will then drive the translation plate 232 to move away from the trigger block 231. One end of the translation plate 232 will first contact the rotating plate 234, thereby driving the rotating plate 234 to rotate. This will cause the small rotating shaft 233 to rotate. Under the combined action of the second slider 237 and the second spiral groove 233-1, the lifting sleeve 236 will move upward, driving the lifting column 2310 to move upward, thereby causing the lifting ring 238 to move upward, so that the locking block 239 engages with the locking groove 221-1. After that, the rotation of the rotating shaft 211 can drive the rotating ring 221 to rotate.

[0061] When the rotating ring 221 drives the rotating disk 222 to rotate, the cylinder 223 slides in the arc groove 222-1. Since the moving plate 224 can only move horizontally, it drives the arc plate 225 to move outward and gradually fits tightly against the inner wall of the sleeve 31 of the release film 3. A friction block is fixed on the arc plate 225 to increase the friction between the arc plate 225 and the inner wall of the sleeve 31, thereby completing the expansion and tightening of the inner wall of the sleeve 31. Then, the threaded column 2111 is tightened, and the end face of the threaded column 2111 will gradually fit against the end face of the feeding shaft 12. Then, under the action of friction, the rotation of the handle 2110 can be restricted, thereby restricting the rotation of the feeding shaft 12, thereby locking the position of the arc plate 225 and ensuring that the release film 3 is accurately and stably installed.

[0062] When it is necessary to remove the release film 3, loosen the threaded post 2111, rotate the handle 2110 in the opposite direction to reset the arc plate 225 and the stop block 216, and then the release film 3 can be removed.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
