Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting products, in particular to a dust-proof falling air curtain device. Background Art

[0002] At present, the die-cutting machine is a device that performs die-cutting on self-adhesive materials, protective films, electronic shielding materials, PVC / film Mylar paper, copper-aluminum foil, double-sided tape or foam and other materials, as well as LCD reflective films, diffusers, buffer films, brightening films or silicone tapes in the optoelectronic industry. It is widely used in printing, electronics, IT, automobile and other manufacturing industries.

[0003] During the die-cutting process, at least one layer of protective film will be attached to the surface of the substrate. The protective film will be cut in advance according to the width of the substrate before use, and the cut protective film will be rewound onto the roller for subsequent loading. During the production process, the protective film roll is set above the die-cutting mechanism. The cut protective film will have more or less debris on its side. When the protective film is rolled and loaded, the debris on it will fall from top to bottom onto the substrate to be die-cut at the bottom, affecting the substrate processing.

[0004] Therefore, it is necessary to provide a dust-proof falling air curtain device to solve the above problems. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the utility model is to provide a dust-proof falling air curtain device to prevent the debris on the upper side of the coil from falling onto the surface of the substrate to be die-cut when the coil is wound and fed, thereby ensuring the processing efficiency of the substrate coating die-cutting.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a dust-proof falling air curtain device, which is installed in a substrate die-cutting device, wherein the substrate die-cutting device includes a substrate feeding assembly and a plurality of coil feeding assemblies and a bottom film feeding assembly respectively located on the upper and lower sides thereof and arranged along the length direction of the substrate die-cutting device, including a dust-proof assembly located between the coil feeding assembly and the substrate feeding assembly; the dust-proof assembly includes a horizontally arranged dust-proof air pipe, one end of the dust-proof air pipe is sealed, and the other end is connected to an air supply mechanism, and a plurality of air injection holes perpendicular to the substrate feeding direction are horizontally spaced on the dust-proof air pipe. When air is supplied, gas can be ejected from the plurality of air injection holes and form an uninterrupted air curtain on at least one side of the length direction of the dust-proof air pipe.

[0007] Furthermore, the dustproof air pipe is at least two branch pipes connected end to end by a connecting switch. For a long laminating and die-cutting production line, a connecting switch is used to connect multiple branch pipes to facilitate installation, operation and maintenance by the staff.

[0008] Further, the air jet holes on the dust-proof air pipe correspond to the positions of multiple coil loading components. In some embodiments, when some of the coil loading components are not working, the staff can wrap the air jet holes at the corresponding positions on the dust-proof air pipe with tape.

[0009] Further, the dust-proof component further includes an air pipe fixing bracket for supporting the dust-proof air pipe. The air pipe fixing bracket includes a fixing base, and an air pipe placement cavity for placing the dust-proof air pipe is formed on the fixing base. By providing this air pipe fixing base, it not only supports the dust-proof air pipe but also facilitates the installation of the dust-proof air pipe.

[0010] Further, the air pipe placement cavity is an arc-shaped structure recessed from the upper surface of the fixing base towards its interior. On the fixing base, there are support seats and threaded holes located on both sides of the air pipe placement cavity. The locking screw passes through the support seat and is threadedly connected to the threaded hole. The top of the fixing base is an open structure, and the dust-proof air pipe can be directly placed into the air pipe placement cavity from top to bottom, which is more convenient than plug-in installation. When fixing, the support seat and the fixing base can be locked by tightening the locking screw. When disassembling, the locking screw can be unscrewed in the reverse direction. This structure facilitates the user to disassemble and replace the dust-proof air pipe at any time.

[0011] Further, the coil loading component includes a plurality of film laminating components and die-cutting components arranged at intervals. The die-cutting component includes a top pressure roller, a die-cutting roller, and a driving roller arranged from top to bottom. The film laminating component is composed of an upper pressure roller and a lower pressure roller arranged up and down. Different coils on the coil loading component are pressed and adhered through the film laminating component. The die-cutting roller is a hob-type die-cutting roller to die-cut the base material into the required shape.

[0012] Further, it further includes an installation bracket. An adjustable distance component is arranged on the installation bracket. The adjustable distance component includes an adjusting screw rod. One end of the adjusting screw rod is threadedly screwed into the guiding groove on the installation bracket, and a connecting block is arranged at its end. The bottom of the connecting block is elastically connected to the upper surface of the connecting plates arranged at both ends of the top pressure roller through a spring. The connecting block at the end of the adjusting screw rod moves up and down along the height direction of the guiding groove under the action of its screwing. When the adjusting screw rod drives the connecting block to move downward or upward, it can push the top pressure roller to move towards or away from the die-cutting roller to adjust the distance between the top pressure roller and the die-cutting roller to meet the die-cutting processing requirements of base materials with different thicknesses.

[0013] Further, it further includes a base material unloading component. The base material loading component, the base material unloading component, the coil loading component, the bottom film loading component, the film laminating component, the die-cutting component, and the dust-proof component are all located on the machine frame. A plurality of feet for supporting the machine frame are arranged at the bottom of the machine frame. The machine frame plays a supporting role for the base material die-cutting equipment and the dust-proof falling air curtain device.

[0014] The beneficial effects of the present utility model:

[0015] In the present utility model, the dust-proof component is arranged between the base material feeding component and the coil feeding component. A plurality of air injection holes are formed in the horizontally arranged dust-proof air pipe. After supplying air, an uninterrupted air curtain formed by the gas ejected through the air injection holes blows all the debris generated on both sides in the length direction of the coil from one side of the coil to the side far away from the base material feeding component, so that when the coil is fed, the debris on each section of the coil fed thereon will not directly fall onto the base material feeding component exactly below it, effectively avoiding affecting the subsequent film laminating and die-cutting of the base material thereon and ensuring the processing efficiency of the base material film laminating and die-cutting.

Detailed Embodiment

[0020] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0021] See the attached Figures 1 to 3As shown in the figure, a dust-proof falling air curtain device in this embodiment is installed in a substrate die-cutting device. The substrate die-cutting device includes a substrate loading assembly 3, and a plurality of roll material loading assemblies 2 and a bottom film loading assembly 5 respectively located on the upper and lower sides thereof and arranged along the length direction of the substrate die-cutting device. It includes a dust-proof assembly 10 located between the roll material loading assembly 2 and the substrate loading assembly 3. The dust-proof assembly 10 includes a horizontally arranged dust-proof air pipe 101. One end of the dust-proof air pipe 101 is sealed, and the other end is connected to a gas supply mechanism to ensure that when gas enters the dust-proof air pipe 101 and is ejected from the air ejection holes 102 thereon, it obtains sufficient air pressure to blow the debris on the roll material away from the dust-proof air pipe 101.

[0022] In some embodiments, see the appendix Figure 1 The dust-proof air pipe 101 is horizontally arranged on the frame 1. When loading the roll material, the whole of it is located outside the dust-proof air pipe 101, so that when the dust-proof air pipe 101 works, it can blow the debris on both sides in the length direction of the roll material away from the roll material from the side, so as to ensure that no debris will directly fall onto the substrate to be processed below the roll material loading assembly 2.

[0023] A number of air ejection holes 102 perpendicular to the substrate loading direction are horizontally and spaced apart on the dust-proof air pipe 101. When supplying gas, the gas can be ejected from a plurality of air ejection holes 102 and form an uninterrupted air curtain on at least one side in the length direction of the dust-proof air pipe 101. Through this uninterrupted air curtain, the debris generated on both sides in the length direction of the roll material from one side of the roll material can be completely blown to the side far away from the substrate loading assembly 3, so that when loading the roll material, the debris on each section of the roll material loaded thereon will not directly fall onto the substrate loading assembly 3 directly below it, effectively avoiding affecting the subsequent film covering and die-cutting of the substrate thereon.

[0024] In some embodiments, the horizontally arranged air ejection holes 102 do not penetrate along the width direction of the dust-proof air pipe 101, and only the side facing the substrate loading assembly 3 is provided with air ejection holes 102, that is, the dust-proof air pipe 101 forms an air curtain on the side facing the substrate loading assembly 3 that can blow the debris on the roll material away from the substrate loading assembly 3. This ensures that when gas enters the dust-proof air pipe 101, it can provide sufficient air flow for each air ejection hole 102 to blow the debris on the side of the roll material away from the substrate.

[0025] The dust-proof air pipe 101 is at least two branch pipes connected end to end through a connection switch 103. For a longer film covering and die-cutting production line, a connection switch 103 is used to connect multiple branch pipes to facilitate the installation operation and maintenance of the staff.

[0026] In some embodiments, see the appendix Figure 1, there are two branch pipes, one end of which away from the connection switch 103 is sealed, and the other end away from the connection switch 103 is connected to the air supply mechanism.

[0027] Specifically, the air supply mechanism can be an air pump or a vacuum generator, including but not limited to the above two, as long as it can supply air to the dust-proof air pipe 101.

[0028] The air jet holes 102 on the dust-proof air pipe 101 correspond to the positions of a plurality of coil loading components 2. In some embodiments, when some of the coil loading components 2 are not working, the staff can wrap the air jet holes 102 at the corresponding positions on the dust-proof air pipe 101 with tape.

[0029] The dust-proof component 10 further includes an air pipe fixing bracket 104 for supporting the dust-proof air pipe 101. The air pipe fixing bracket 104 includes a fixing seat 1041, and an air pipe placement cavity 1042 for placing the dust-proof air pipe 101 is formed on the fixing seat 1041. By setting the air pipe fixing seat 1041, it not only supports the dust-proof air pipe 101 but also facilitates the installation of the dust-proof air pipe 101.

[0030] In some embodiments, the air pipe placement cavity 1042 is a circular through hole that penetrates the air pipe fixing bracket 104 and allows the dust-proof air pipe 101 to be directly inserted. During installation, one end of the dust-proof air pipe 101 can be directly inserted.

[0031] The air pipe placement cavity 1042 is an arc-shaped structure that is recessed from the upper surface of the fixing seat 1041 into its interior. The fixing seat 1041 is provided with support seats 1044 and threaded holes 1043 on both sides of the air pipe placement cavity 1042. The locking screw 1045 passes through the support seat 1044 and is threadedly connected to the threaded hole 1043. The top of the fixing seat 1041 is an open structure, and the dust-proof air pipe 101 can be directly placed in the air pipe placement cavity 1042 from top to bottom, which is more convenient than plug-in installation. When fixing, the support seat 1044 and the fixing seat 1041 can be locked by the locking screw 1045. When disassembling, the locking screw 1045 can be unscrewed in the reverse direction. This structure facilitates the user to disassemble and replace the dust-proof air pipe 101 at any time.

[0032] The coil loading component includes a plurality of film laminating components 6 and die-cutting components 7 arranged at intervals. The die-cutting component 7 includes a top pressing roller 71, a die-cutting roller 72, and a driving roller 73 arranged from top to bottom. The film laminating component 6 is composed of an upper pressing roller and a lower pressing roller arranged up and down. Different coils on the coil loading component 2 are pressed and adhered through the film laminating component 6. The die-cutting roller 72 is a hob type die-cutting roller to die-cut the base material into the required shape.

[0033] It should be noted that the specific quantities of the film laminating assembly 6 and the die-cutting assembly 7 are determined according to the number of layers of the coil material to be attached to the base material and the number of die-cutting times.

[0034] It further includes a mounting bracket 9, on which an adjustable distance assembly 8 is provided. The adjustable distance assembly 8 includes an adjusting screw rod 81. One end of the adjusting screw rod 81 is screwed into the guiding groove 82 on the mounting bracket 9, and a connecting block 84 is provided at its end. The bottom of the connecting block 84 is elastically connected to the upper surface of the connecting plate 83 provided at both ends of the top pressure roller 71 through a spring 85. The connecting block 84 at the end of the adjusting screw rod 81 moves up and down along the height direction of the guiding groove 82 under the screwing action. When the adjusting screw rod 81 drives the connecting block 84 to move downward or upward, it can push the top pressure roller 71 to move towards or away from the die-cutting roller 72, so as to adjust the distance between the top pressure roller 71 and the die-cutting roller 72 to meet the die-cutting processing of base materials with different thicknesses.

[0035] It should be noted that under the elastic action of the spring 85, the top pressure roller 71 will not be completely pressed against the die-cutting roller 72, and thus will not affect the passing of the base material through the die-cutting between the two.

[0036] It further includes a base material discharging assembly 4. The base material loading assembly 3, the base material discharging assembly 4, the coil material loading assembly, the bottom film loading assembly 5, the film laminating assembly 6, the die-cutting assembly 7 and the dust-proof assembly 10 are all located on the frame 1, and a plurality of feet for supporting it are provided at the bottom of the frame 1. The frame 1 plays a supporting role for the base material die-cutting equipment and the dust-proof falling air curtain device.

[0037] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
