Description

Technical Field

[0001] This utility model relates to the technical field of heat transfer film production equipment, and in particular to a composite device for bonding silicone calendered film and hot melt adhesive in roll form of heat transfer film. Background Technology

[0002] Silicone film is widely used in the field of heat transfer film materials due to its excellent heat resistance and elasticity. Calendering is a key step in its production process. This process involves extruding silicone raw materials with one or more pairs of calendering rollers to form a film with a specific thickness.

[0003] In actual production, in order to meet the needs of different customer orders or product specifications, it is necessary to frequently adjust the distance between calendering rollers to change the thickness of the silicone film. This is a necessary operation to ensure product diversity and market adaptability.

[0004] Currently, conventional calendering equipment often uses screw and nut mechanisms or manual bolt adjustments to adjust the calendering roll spacing. These methods are cumbersome, requiring operators to use tools for multiple rotations and measurements. The entire adjustment process is time-consuming, limiting production efficiency. Furthermore, the locking and fixing effect of these traditional adjustment structures is often unstable after the spacing adjustment is completed. Mechanical vibrations generated during long-term high-load operation can easily cause slight deviations in the set roll spacing. These deviations directly lead to uneven thickness of the produced silicone film, increasing the product defect rate and affecting production stability and final product quality.

[0005] Therefore, this utility model proposes a composite device for bonding silicone calendered film and hot melt adhesive to roll heat transfer film material to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of silicone calendered film and hot melt adhesive laminating roll heat transfer film composite device, such as cumbersome and time-consuming adjustment of calendering roller spacing and unstable locking effect, resulting in low product accuracy, this utility model aims to provide a silicone calendered film and hot melt adhesive laminating roll heat transfer film composite device with improved structure that can effectively solve the above problems.

[0007] This utility model provides a composite device for bonding silicone calendered film and hot melt adhesive in roll form, including a worktable, a calendering roller adjustablely mounted on the worktable, and an adjustment component.

[0008] The adjustment component is an innovative structure for quickly adjusting and locking the position of the calendering roll. It includes an adjustment column fixed to the worktable, a pressing block slidably mounted on the adjustment column, and a first spring sleeved on the adjustment column and elastically disposed between the pressing block and the worktable.

[0009] Furthermore, the adjustment assembly also includes a connecting block and a locking block fixed on the connecting block. The connecting block is connected to the pressing block through a first connecting post that is fixedly connected. The interior of the calender roll has a corresponding first locking groove. In the assembled state, the locking block engages with the first locking groove under the return force of the first spring. By pressing the pressing block, the locking block can be disengaged from the first locking groove. After releasing the hand, it can automatically reset and lock. This linkage structure realizes convenient, fast and reliable adjustment of the calender roll spacing.

[0010] Preferably, the calendering roll includes at least two parallel rollers, and through the synergistic action of multiple rollers, the silicone raw material can be calendered more uniformly.

The pressing plate and the first connecting plate are connected by a second connecting post. This structure is used for quick loading and unloading of the take-up roller.

[0012] Preferably, as a further optimization of the replacement component, the replacement component also includes a third connecting column fixed to the worktable, a second connecting plate fixed to the third connecting column, and a second spring located between the pressing plate and the second connecting plate. The second spring provides the pressing plate with the ability to automatically reset, making the operation more labor-saving and convenient.

[0013] Preferably, a second slot is provided on the worktable. One end of the take-up roller is axially limited by a limiting post, and the other end is engaged in the second slot. The stability of the take-up roller during operation is ensured by the cooperation and limiting of the two ends.

[0014] Preferably, the apparatus further includes a cooling zone, which is located on the silicone film conveying path between the calendering roller and the winding roller, for forced cooling and shaping of the high-temperature silicone film that has just been calendered, to prevent sticking during winding.

[0015] Preferably, the apparatus further includes an unwinding roller, a hot melt adhesive roller, and a laminating roller, which are used to perform the lamination process, wherein the take-up roller can be transferred to the position of the unwinding roller for unwinding after being fully wound with the silicone film.

[0016] Preferably, the discharge paths of the unwinding roller and the hot melt adhesive roller intersect before the composite roller, so that the silicone film and the hot melt adhesive can smoothly enter the composite roller simultaneously for pressing, thus completing the final composite film preparation.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 4 This utility model provides a composite device for bonding silicone calendered film and hot melt adhesive to roll heat transfer film material, which aims to solve the problems of complex and unstable adjustment mechanism of calendering roller 2 and time-consuming loading and unloading of roll material in the prior art.

[0029] like Figure 1 As shown, the silicone calendered film and hot melt adhesive laminated roll heat transfer film composite device includes a worktable 1 and a calendering roller 2 adjustablely mounted on the worktable 1. The worktable 1 serves as the mounting base for the entire device, providing support for each component. The calendering roller 2 is used to press the block-shaped silicone raw material into sheets. Specifically, the calendering roller 2 includes at least two parallel rollers.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 To achieve rapid adjustment and stable locking of the position of the calender roll 2, the device also includes an adjustment assembly 8. The adjustment assembly 8 includes an adjustment column 803 that slides on the take-up roll 7, a pressing block 801 that is slidably mounted on the adjustment column 803, a first spring 802 that is sleeved on the adjustment column 803, and the two ends of the first spring 802 that are elastically set on the pressing block 801 to provide a restoring force. The adjustment assembly 8 also includes a first connecting column 804, one end of which is fixedly connected to the pressing block 801, and the other end of which is fixedly connected to a connecting block 805. A locking block 806 is fixedly fixed to the connecting block 805. A first locking groove 807 is provided inside the calender roll 2. Under the reset force of the first spring 802, the locking block 806 can engage with the first slot 807. When it is necessary to adjust the spacing of the calendering roller 2, the operator presses the pressing block 801. The pressing block 801 overcomes the elastic force of the first spring 802 and slides along the adjusting column 803. At the same time, the connecting block 805 is moved through the first connecting column 804, causing the locking block 806 to disengage from the first slot 807. At this time, the calendering roller 2 is unlocked and its position can be adjusted. After adjusting to the appropriate position, the pressing block 801 is released. Under the elastic force of the first spring 802, the locking block 806 automatically engages in the new first slot 807, thereby completing the rapid adjustment and reliable fixation of the calendering roller 2.

[0031] Please refer to Figure 2and Figure 4 The take-up roller 7 is used to take up the calendered and cooled silicone film. It is detachably installed on the worktable 1. To achieve quick assembly and disassembly, the take-up roller 7 has an annular limiting groove 906 inside. The replacement component 9 is installed on the worktable 1. Its function is to cooperate with the limiting groove 906 of the take-up roller 7 to achieve quick locking and unlocking of the take-up roller 7. The replacement component 9 includes a pressing plate 901 that can be fixedly installed on the take-up roller 7, a first connecting plate 904, and a limiting post 905 fixed on the first connecting plate 904. A second connecting post 903 is connected between the pressing plate 901 and the first connecting plate 904. In the assembled state, the limiting post 905 can be inserted into the limiting groove 906 of the take-up roller 7 to axially limit one end of the take-up roller 7.

[0032] Meanwhile, to achieve automatic reset and labor-saving operation of the replacement component 9, the replacement component 9 also includes a third connecting post 909 fixed to the workbench 1, a second connecting plate 908 fixed to the third connecting post 909, and a second spring 902 located between the pressing plate 901 and the second connecting plate 908. When it is necessary to remove the take-up roller 7, the operator presses the pressing plate 901. The pressing plate 901 overcomes the elastic force of the second spring 902 and drives the first connecting plate 904 to move through the second connecting post 903, causing the limiting post 905 to disengage from the limiting groove 906. At this time, the end of the take-up roller 7 loses its limit. To further stabilize the installation of the take-up roller 7, a second slot 907 is also provided on the workbench 1. The other end of the take-up roller 7 is engaged in the second slot 907. When the limiting post 905 disengages, the take-up roller 7 can be taken out from the second slot 907. This quick-change structure of pressing and unlocking ensures that the fully wound take-up roller 7 can be quickly replaced during the production process, improving production efficiency.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] In a preferred embodiment, to rapidly cool and shape the calendered silicone film and prevent it from sticking or deforming during winding, the device further includes a cooling zone 3. Please refer to [reference needed]. Figure 1 The cooling zone 3 is located on the silicone film conveying path between the calendering roll 2 and the winding roll 7. Before being wound up by the winding roll 7, the silicone film coming out of the calendering roll 2 will pass through the cooling zone 3. The cooling zone 3 can be an air-cooled device or a water-cooled roll structure to ensure that the silicone film reaches the appropriate temperature and shape before entering the winding process.

[0035] In another preferred embodiment, to complete the final lamination process, the apparatus further includes an unwinding roller 4, a hot melt adhesive roller 5, and a laminating roller 6. Please refer to [reference needed]. Figure 1When the silicone film on the take-up roller 7 is fully rolled up and removed, it can be installed in the position of the unwind roller 4. The unwind roller 4 is used to release the silicone film, and the hot melt adhesive roller 5 is used to provide the hot melt adhesive layer. The output paths of the unwind roller 4 and the hot melt adhesive roller 5 intersect before the composite roller 6. The silicone film and the hot melt adhesive are tightly bonded together under the pressure of the composite roller 6 to form the final heat transfer film composite product.

[0036] The working principle of this utility model's device for laminating silicone calendered film and hot melt adhesive into roll-shaped heat transfer film is as follows:

[0037] When silicone needs to be calendered and wound, firstly, the spacing of the calendering rollers 2 is adjusted by adjusting component 8. During operation, press the pressing block 801 to deform the first spring 802 sleeved between the pressing block 801 and the worktable 1. At the same time, the first connecting post 804 fixed outside the pressing block 801 moves synchronously with the connecting block 805, thereby causing the locking block 806 fixed outside the connecting block 805 to disengage from the first slot 807 opened inside the calendering roller 2. After adjusting to the appropriate position, release the pressing block 801. Under the reset force of the first spring 802, the locking block 806 is re-locked into the first slot 807, achieving quick fixation after adjustment. Then, the block silicone is placed under the calendering roller 2 for sheet pressing. Subsequently, the calendered silicone film is shaped in the cooling zone 3. Finally, the cooled silicone film is wound onto the winding roller 7.

[0038] When the take-up roller 7 needs to be removed and transferred, it can be quickly replaced by the replacement component 9. During operation, press the pressing plate 901, and the first connecting plate 904 moves synchronously through the second connecting post 903. At the same time, the second spring 902 located between the pressing plate 901 and the second connecting plate 908 deforms. The second connecting plate 908 is fixed on the worktable 1 by the third connecting post 909. When the first connecting plate 904 moves, the limiting post 905 fixed outside it disengages from the limiting groove 906 opened in the take-up roller 7. At this time, the other end of the take-up roller 7 can be disengaged from the second slot 907, and the take-up roller 7 can be quickly removed. Through the synergistic effect of the adjustment component 8 and the replacement component 9, this utility model solves the problems of inconvenient adjustment and time-consuming roll replacement in the prior art.

[0039] Finally, the removed take-up roller 7 is placed in the position of the unwind roller 4. The hot melt adhesive roller 5 and the silicone film on the unwind roller 4 meet in front of the composite roller 6 and are combined by the composite roller 6 to complete the final lamination and winding work.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
