Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a pull-coating structure for coating. Background Technology

[0002] Tensile membrane structures possess flexibility and resilience; their surfaces can be shaped into curved forms through tension to adapt to changes in external loads. Once the basic membrane structure is established, the remaining task is to apply an outer coating. Polytetrafluoroethylene (PTFE) and silicone are durable coatings that protect against UV radiation, moisture, and microbial contamination. Therefore, the tensile membrane needs to be stretched and unfolded to ensure its flatness.

[0003] Common stretch coating structures can only stretch the membrane, but lack the function of preventing tearing. When stretching the membrane, if the applied stretching force is too large or the stretching distance exceeds the limit that the membrane material itself can withstand, it is very easy to induce serious consequences such as tearing or breaking of the membrane. This membrane damage caused by excessive stretching will directly destroy the integrity and uniformity of the coating process, affecting the final performance of the product.

[0004] Therefore, in response to the problem that the tensile membrane is prone to tearing or breaking when the lifting action is performed due to the lack of anti-tear function, resulting in a decline in the final performance of the product, a lifting coating structure for coating can be designed. Utility Model Content

[0005] To overcome the lack of anti-tear function, if the force is too great or the distance exceeds the tensile membrane's tolerance limit when performing the lifting action, it is very easy to cause the tensile membrane to tear or break, resulting in a decline in the final performance of the product.

[0006] The technical solution of this utility model is as follows: a lifting coating structure for coating film, including a supporting base plate; it also includes a supporting wall and movable baffles. The supporting wall is fixedly connected to the top of the supporting base plate. Two sliding grooves are opened on the front side of the supporting wall. Multiple limiting shafts are rotatably connected inside the sliding grooves. Multiple movable baffles are slidably connected inside the sliding grooves. The movable baffles are slidably connected to the limiting shafts. A push-pull handle is fixedly connected to the rear side of the movable baffles. A film-supporting mechanism is provided on the supporting base plate for supporting the tensioned membrane. A lifting mechanism is provided on the supporting base plate for lifting the tensioned membrane to maintain its flatness.

[0007] Preferably, the movable baffle is adjusted according to the size and ultimate tensile strength of the tensile membrane. During operation, the movable baffle is pushed to the appropriate position by pushing and pulling the handle, so that it moves towards the connecting plate, thereby pushing the movable baffle out of the sliding groove. At the same time, the movement range of the movable baffle is limited by the limiting shaft to prevent the movable baffle from disengaging from the sliding groove. When the C-shaped plate moves the connecting plate, the pushed-out movable baffle will block the connecting plate, thereby preventing the C-shaped plate from moving too far and causing the tensile membrane to tear or break, thus achieving the function of preventing tearing.

[0008] Preferably, the lifting mechanism includes a driving component and a clamping component, wherein the driving component is used to control the horizontal movement of the clamped tension membrane, and the clamping component is used to clamp the tension membrane.

[0009] Preferably, the drive assembly includes two support legs fixed to the top of the support base plate, a drive frame fixed to the top of the support legs, a bidirectional lead screw rotatably connected to the inside of the drive frame, and a rotating handle fixedly connected to the right end of the bidirectional lead screw.

[0010] Preferably, the clamping assembly includes a drive block slidably connected to the inside of the drive frame, a connecting rod fixed to the rear of the drive block, an inverted plate fixed to the end of the connecting rod away from the drive block, a connecting plate fixed to the rear of the inverted plate, two telescopic rods fixed to the inside of the inverted plate, a clamping plate fixed to the top of the telescopic rod, and two springs fixed to the inside of the inverted plate. The drive block is threadedly connected to a bidirectional lead screw, and the top of the spring is fixedly connected to the bottom of the clamping plate.

[0011] Preferably, the membrane support mechanism includes a flattening component and a sliding component. The flattening component is used to support the flat tension membrane, and the sliding component is used to support the clamping component.

[0012] Preferably, the film support mechanism includes a coating platform fixedly connected to the top of the support base plate, and the coating platform is at the same horizontal plane as the tensioned membrane after it is pulled up.

[0013] Preferably, the sliding assembly includes two support platforms fixedly connected to the top of the support base plate and multiple rollers rotatably connected to the top of the support platforms.

[0014] The beneficial effects of this utility model are:

[0015] The advantage of this structure lies in its adjustable position design of the movable baffle, which can precisely adapt to tensile membranes of different sizes and ultimate tensile strengths. Combined with the effective limitation of its movement range by the limiting shaft, it prevents accidental detachment while ensuring that when the C-shaped plate drives the connecting plate to move beyond the safety threshold, the pushed-out movable baffle can form a reliable physical block, thereby actively preventing excessive displacement of the connecting plate. This fundamentally avoids the risk of tearing or breaking of the tensile membrane due to overstretching, significantly improving the reliability of equipment operation, the effectiveness of material protection, and overall safety.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a tension coating structure, including a supporting base plate 1; it also includes a supporting wall 11 and movable baffles 14. The supporting wall 11 is fixedly connected to the top of the supporting base plate 1. Two sliding grooves 12 are opened on the front side of the supporting wall 11. Multiple limiting shafts 13 are rotatably connected inside the sliding grooves 12. Multiple movable baffles 14 are slidably connected inside the sliding grooves 12. The movable baffles 14 are slidably connected to the limiting shafts 13. A push-pull handle 15 is fixedly connected to the rear side of the movable baffles 14. A film-supporting mechanism is provided on the supporting base plate 1 for supporting the tensioned membrane. A lifting mechanism is provided on the supporting base plate 1 for lifting and holding the tensioned membrane. The flatness of the movable baffle 14 is adjusted according to the size of the tensile membrane and the ultimate tensile strength it can withstand. The movable baffle 14 is pushed towards the connecting plate 324 by the push-pull handle 15, so that the movable baffle 14 is pushed out from the inside of the sliding groove 12. At the same time, the movement range of the movable baffle 14 is limited by the limiting shaft 13, thereby preventing the movable baffle 14 from disengaging from the sliding groove 12. When the C-shaped plate 323 drives the connecting plate 324 to move, the connecting plate 324 is blocked by the movable baffle 14 that has been moved out, thereby preventing the C-shaped plate 323 from moving too far and causing the tensile membrane to tear or break, thus achieving the function of preventing tearing.

[0025] Please see Figures 2-6In this embodiment, the lifting mechanism includes a driving component and a clamping component. The driving component controls the horizontal movement of the clamped tension membrane, and the clamping component clamps the tension membrane. The driving component and the clamping component together form a complete lifting mechanism, which cooperate to lift the tension membrane and maintain its flatness. The driving component includes two support legs 311 fixed to the top of the support base plate 1, a driving frame 312 fixed to the top of the support legs 311, a bidirectional lead screw 313 rotatably connected to the inside of the driving frame 312, and a rotating handle 314 fixedly connected to the right end of the bidirectional lead screw 313. By rotating the bidirectional lead screw 313 through the rotating handle 314, the bidirectional lead screw 313 drives the two driving blocks 321 to move away from each other. The clamping component includes a component slidably connected to the inside of the driving frame 312. The system includes a drive block 321, a connecting rod 322 fixed to the rear side of the drive block 321, an inverted plate 323 fixed to the end of the connecting rod 322 away from the drive block 321, a connecting plate 324 fixed to the rear side of the inverted plate 323, two telescopic rods 325 fixed to the inner side of the inverted plate 323, a clamping plate 326 fixed to the top of the telescopic rod 325, and two springs 327 fixed to the inner side of the inverted plate 323. The drive block 321 is threadedly connected to a two-way lead screw 313. The top of the spring 327 is fixedly connected to the bottom of the clamping plate 326. The two drive blocks 321, which are far apart from each other, drive the two inverted plates 323, which are far apart from each other, through the two connecting rods 322. The two inverted plates 323 then drive the two ends of the tension membrane that are clamped to move in opposite directions until the tension membrane is pulled up and flattened.

[0026] Please see Figures 1-6 In this embodiment, the membrane support mechanism includes a flattening component and a sliding component. The flattening component supports the flat tensile membrane, and the sliding component supports the clamping structure. The flattening component and the sliding component combine to form a complete membrane support mechanism, which cooperates to support the tensile membrane. The membrane support mechanism includes a coating platform 211 fixedly connected to the top of the support base plate 1. The coating platform 211 is at the same horizontal plane as the tensile membrane after it has been pulled up and flattened, and it lies flat on the coating platform. The top of the film stage 211 supports the tensile membrane. The sliding assembly includes two support platforms 221 fixedly connected to the top of the support base plate 1 and multiple rollers 222 rotatably connected to the top of the support platforms 221. When the connecting rod 322 drives the C-shaped plate 323 to move, the C-shaped plate 323 moves along the top of the support platform 221. The rollers 222 rotate through friction with the C-shaped plate 323, thereby ensuring the smooth movement of the C-shaped plate 323.

[0027] During operation, the movable baffle 14 is first adjusted according to the size and ultimate tensile strength of the tensile membrane. During operation, the movable baffle 14 is pushed to the appropriate position using the push-pull handle 15, moving it towards the connecting plate 324, thereby pushing the movable baffle 14 out of the sliding groove 12. Simultaneously, the movement range of the movable baffle 14 is limited by the limiting shaft 13 to prevent it from detaching from the sliding groove 12. The tensile membrane is then placed on top of the coating table 211, and the clamping plate 326 is pushed downwards. At this time, the telescopic rod 325 and spring 327 are compressed. Then, both ends of the tensile membrane are inserted into the C-shaped plate 323, the clamping plate 326 is released, and then the spring 32... The thrust of 7 pushes the clamping plate 326 upward until the clamping plate 326, together with the C-shaped plate 323, clamps the tensile membrane. After the tensile membrane is clamped, the double-acting screw 313 is rotated by rotating the handle 314. The double-acting screw 313 drives the two drive blocks 321 to move away from each other. The two drive blocks 321, which move away from each other, drive the two C-shaped plates 323 to move away from each other through the two connecting rods 322. The two C-shaped plates 323, which move away from each other, drive the two ends of the tensile membrane that are clamped to move in opposite directions until the tensile membrane is pulled up and flattened. After the tensile membrane is pulled up and flattened, it is placed flat on the top of the coating table 211. The coating table 211 supports the tensile membrane, and then the coating operation can be performed on the surface of the tensile membrane.

[0028] Through the above steps, the movable baffle 14 is pushed along the sliding groove 12 towards the connecting plate 324 by the push-pull handle 15. When the C-shaped plate 323 moves the connecting plate 324, the movable baffle 14 that has been pushed out forms a blockage to prevent the C-shaped plate 323 from moving excessively and causing the tensile membrane to tear or break, thus achieving the anti-tear-tearing function. This solves the problem that common coating lifting structures can only lift the tensile membrane but lack the anti-tear-tearing function. When the lifting action is performed, if the force is too large or the distance exceeds the tensile membrane's bearing limit, it is very easy to cause the tensile membrane to tear or break, affecting the final performance of the product.
