Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, specifically to a film applicator with a hot pressure roller positioning and connection structure. Background Technology

[0002] A film applicator is a machine specifically designed for applying protective films and explosion-proof films to industries such as electronics, communications, and semiconductors. It ensures that the film is applied without bubbles or scratches. The electronics and information industry is one of the most dynamic and rapidly developing industries today. The manufacturing technology of electronic products is a key technology in the information industry chain. In the manufacturing process of electronic products, there is a production process that requires applying films to glass products.

[0003] The hot press rollers of existing film applicators are mostly fixed directly to the cable tray with bolts at both ends, making the hot press rollers and the cable tray an integrated connection. However, this connection method means that when the cable tray needs to be inspected and maintained, manual labor is required to either remove the cable tray along with the hot press rollers, which increases the overall weight of the cable tray and makes it difficult to carry, or remove the hot press rollers first and then remove the cable tray, which increases the workload and is time-consuming and labor-intensive. Utility Model Content

[0004] To solve the above-mentioned technical problems, a film applicator with a hot-pressing roller positioning and connection structure is provided. This solves the problem that in the prior art, the two ends of the hot-pressing roller of the film applicator are mostly directly fixed to the cable tray with bolts, making the hot-pressing roller and the cable tray an integrated connection. However, this connection method means that when the cable tray needs to be inspected and maintained, manual labor is required to either remove the cable tray along with the hot-pressing roller, which increases the overall weight of the cable tray and makes it difficult to carry, or remove the hot-pressing roller first and then remove the cable tray, which increases the workload and is time-consuming and labor-intensive.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a film applicator with a hot pressure roller positioning and connection structure, comprising a film applicator body, a first pressure roller detachably mounted on the top surface of the film applicator body, and a second rotating roller detachably disposed between the inner walls on both sides of the first pressure roller. The second pressure roller is rotatably sleeved on the rod of the second rotating roller. Connecting pieces detachably connected to the outer wall of the film applicator body are fixed on both sides of the first pressure roller. Shrinkage channels are provided on both sides of the top surface of the film applicator body. A positioning and lifting part for assisting in supporting the second rotating roller when the first pressure roller is disassembled is provided in the shrinkage channel. An insertion channel corresponding to and communicating with the shrinkage channel is provided in the inner side wall of the first pressure roller. Buffer grooves are provided at both ends of the second rotating roller. A magnetic locking part that cooperates with the positioning and lifting part is built into the buffer groove.

[0006] The positioning and lifting part includes a movable rod that is vertically slidably disposed in the shrinkage channel. A plurality of compression springs are fixed at equal intervals between the bottom end of the movable rod and the inner wall of the bottom end of the shrinkage channel. An L-shaped connecting frame that cooperates with the movable rod is slidably disposed on the inner side wall of the film applicator body. One end of the connecting frame is fixed with a bearing plate corresponding to the end of the second rotating roller.

[0007] The magnetic locking part includes a positioning block that is slidably disposed in the buffer groove. One end of the positioning block passes through the contraction channel, and a buffer spring is fixed between the other end of the positioning block and the innermost inner wall of the buffer groove. A first magnetic block is embedded and fixed at the top of the movable rod, and a second magnetic block is embedded and fixed at the end of the positioning block away from the buffer groove.

[0008] Preferably, a locking screw is threaded through the side of the connecting piece away from the body of the film applicator, and a fixing hole adapted to the locking screw is opened on the body of the movable rod. One end of the locking screw passes through the shrink channel and extends into the fixing hole.

[0009] Preferably, the inner sidewall of the film applicator body is provided with a first sliding slit that communicates with the shrink channel, and the other end of the connecting frame passes through the first sliding slit and is fixedly connected to the movable rod.

[0010] Preferably, a second sliding slit communicating with the shrink channel is provided on the outer wall of the film applicator body, and a handle that is slidably disposed in the second sliding slit and perpendicularly fixed to the movable rod is provided.

[0011] Compared with the prior art, the advantages of this utility model are as follows: By setting up the positioning and lifting part and the magnetic locking part, during the process of disassembling the first pressure roller and releasing the fixed relationship between the connecting piece and the film applicator body, the movable rod in the positioning and lifting part is simultaneously released from the fixed position in the shrinkage channel. Then, under the elastic force of the compression spring, the movable rod quickly rises in the inner side of the insertion channel. This allows the connecting frame to slide synchronously upward along the inner wall of the film applicator body, so that the bearing plate can be clamped at the end of the second roller from below to assist in supporting the second roller. At the same time, it can also form a repulsive force on the magnetic locking part to disconnect the connection between the second roller and the first pressure roller.

[0012] Thus, the automatic unlocking and positioning lifting mechanism between the second roller and the first pressure roller provides stable support for the entire second roller and the first pressure roller, eliminating the need for manual disassembly of the second roller, saving time and effort, and facilitating the separate removal of the first pressure roller, reducing the weight during transportation.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1-3 As shown, a film applicator with a hot pressure roller positioning and connection structure includes a film applicator body 1, a first pressure roller 4 detachably installed on the top surface of the film applicator body 1, a bridge frame 2 rotatably disposed between the inner walls of both sides of the film applicator body 1, and a second rotating roller 5 detachably disposed between the inner walls of both sides of the first pressure roller 4. The second pressure roller 6 is rotatably sleeved on the rod of the second rotating roller 5, and the first rotating roller 3 is rotatably sleeved on the rod of the bridge frame 2. Both sides of the first pressure roller 4 are fixed with connecting pieces 7 detachably connected to the outer wall of the film applicator body 1.

[0019] When inspecting and maintaining the first pressure roller 4, the operator only needs to disconnect the connection between the connecting piece 7 and the film applicator body 1, which makes it easy to remove the first pressure roller 4 from the film applicator body 1.

[0020] However, in the existing technology, the two ends of the second roller 5 are mostly fixed directly to the first pressure roller 4 with bolts, so that the second roller 5 and the second pressure roller 6 are integrated with the first pressure roller 4. However, this connection method means that when the cable tray needs to be inspected and maintained, manual labor is required to either remove the first pressure roller 4 along with the second roller 5 and the second pressure roller 6, which increases the overall weight of the first pressure roller 4 and makes it difficult to carry, or to remove the second roller 5 and the second pressure roller 6 first and then remove the first pressure roller 4, which increases the workload and is time-consuming and labor-intensive.

[0021] Therefore, referring to Figure 1-3As shown, it is worth noting that shrink channels are provided on both sides of the top of the film applicator body 1. The shrink channels are provided with positioning and lifting parts for assisting in supporting the second roller 5 when the first pressure roller 4 is disassembled. The inner side wall of the first pressure roller 4 is provided with an insertion channel 11 that corresponds to and communicates with the shrink channels. Both ends of the second roller 5 are provided with buffer grooves 8. The buffer grooves 8 are provided with magnetic locking parts that cooperate with the positioning and lifting parts.

[0022] The positioning and lifting part includes a movable rod 12 that is vertically slidably disposed in the shrinkage channel. Several compression springs 16 are fixed at equal intervals between the bottom end of the movable rod 12 and the inner wall of the bottom end of the shrinkage channel. An L-shaped connecting frame 13 that cooperates with the movable rod 12 is slidably disposed on the inner side wall of the film applicator body 1. One end of the connecting frame 13 is fixed with a bearing plate 14 corresponding to the end of the second roller 5.

[0023] By setting up the positioning support and the magnetic locking part, during the process of disassembling the first pressure roller 4 and releasing the fixed relationship between the connecting piece 7 and the film applicator body 1, the movable rod 12 in the positioning support is simultaneously released from the fixed position in the shrinkage channel. Then, under the elastic force of the compression spring 16, the movable rod 12 quickly rises inside the insertion channel 11. This causes the connecting frame 13 to slide up synchronously along the inner wall of the film applicator body 1, so that the bearing plate 14 can be clamped at the end of the second roller 5 from below to assist in supporting the second roller 5. It can also generate a repulsive force on the magnetic locking part to disconnect the connection between the second roller 5 and the first pressure roller 4.

[0024] Thus, the automatic unlocking and positioning lifting part between the second roller 5 and the first pressure roller 4 provides stable support for the second roller 5 and the second pressure roller 6 as a whole, which not only eliminates the need for manual disassembly of the second roller 5, saving time and effort, but also facilitates the separate removal of the first pressure roller 4, reducing the weight during transportation.

[0025] Furthermore, referring to Figure 3 As shown, it is worth noting that the magnetic locking part includes a positioning block 9 that is slidably disposed in the buffer groove 8. One end of the positioning block 9 is inserted into the contraction channel, and a buffer spring 10 is fixed between the other end of the positioning block 9 and the innermost inner wall of the buffer groove 8. A first magnetic block is embedded and fixed at the top of the movable rod 12, and a second magnetic block is embedded and fixed at the end of the positioning block 9 away from the buffer groove 8.

[0026] As shown above, when the movable rod 12 is unlocked, it rises rapidly inside the insertion channel 11 under the elastic force of the compression spring 16. The movable rod 12 carries the first magnetic block to the position corresponding to the second magnetic block. For this reason, the buffer spring 10 contracts under the magnetic repulsion, thereby effectively releasing the connection between the second rotating roller 5 and the first pressure roller 4.

[0027] Furthermore, referring to Figure 3As shown, it is worth noting that a first sliding slit connected to the shrink channel is also provided on the inner side wall of the film applicator body 1, and the other end of the connecting frame 13 passes through the first sliding slit and is fixedly connected to the movable rod 12.

[0028] With the first sliding joint, when the movable rod 12 rises rapidly under the force of the compression spring 16, one end of the connecting frame 13 passes through the first sliding joint and is fixed to the movable rod 12. The connecting frame 13 then rises synchronously with the movable rod 12, pushing the bearing plate 14 closer to the end of the second roller 5.

[0029] Furthermore, referring to Figure 3 As shown, it is worth noting that the connecting piece 7 has a locking screw 17 threaded through the side away from the film applicator body 1, and the movable rod 12 has a fixing hole that matches the locking screw 17. One end of the locking screw 17 passes into the shrink channel and extends into the fixing hole.

[0030] Tighten the knob to lock the screw 17, causing the screw 17 to exit sequentially from the fixing hole and the inner wall of the film applicator body 1 under the thread structure. This releases the connection between the connecting piece 7 and the film applicator body 1, and also releases the fixing effect on the movable rod 12. Under the elastic force of the compression spring 16, the movable rod 12 quickly carries the connecting frame 13 upward, causing the bearing plate 14 to lock the end of the second roller 5 from below.

[0031] Furthermore, referring to Figure 3 As shown, it is worth noting that a second sliding slit connected to the shrink channel is provided on the outer wall of the film applicator body 1, and a handle 15 that is slidably fixed to the movable rod 12 is provided in the second sliding slit.

[0032] By setting the handle 15, pulling down the handle 15 causes the movable rod 12 to slide down into the contraction channel and compress the compression spring 16, thereby separating the support plate 14 from the second roller 5, eliminating the auxiliary support effect of the support plate 14 on the second roller 5, and also causing the first and second magnets to no longer correspond, so that the positioning block 9 is inserted into the insertion channel 11 under the elastic force of the buffer spring 10, and the second roller 5 is fixedly connected to the first pressure roller 4 again.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
