Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, and in particular to a dust removal device for chlorine-free printing of high-transparency PETG film. Background Technology

[0002] Film printing machines are widely used in various packaging fields. They generally transfer ink onto a substrate using a printing plate. In current printing work, it is common to encounter situations where the substrate needs to be printed on both sides. In order to ensure the quality of film printing, dust removal devices are used to remove dust or hair from the film.

[0003] In the prior art, such as Chinese Patent No. CN222628898U, a dust removal device for a double-sided film printing machine is disclosed, relating to the field of film printing. It aims to solve the problem of poor dust and hair removal efficiency caused by the strong electrostatic adsorption of plastic film. The key technical points are: a placement platform, a take-up drum fixedly connected to the placement platform, a printing mechanism, and an unwinding drum. A fixed rod is fixedly connected to the placement platform, and two adhesive tubes are rotatably connected to the fixed rod. A placement frame is fixedly connected to the placement platform between the fixed rod and the unwinding drum. A second placement frame is fixedly connected to the placement platform between the fixed rod and the printing mechanism. A sliding plate is slidably connected to the first and second placement frames, and a sponge block is fixedly connected to the sliding plate. This dust removal device for a double-sided film printing machine can effectively clean stubborn dust adsorbed by electrostatics, preventing damage to printing quality.

[0004] While the above solution has the advantages mentioned above, it also has the following disadvantages: Although the electric push rod can drive the pressure plate to squeeze the sponge block downwards, and the pressure plate will contact the cutter as it continues to move downwards, at which point the failed part of the sponge block will be cut off, and the cut-off sponge block will be carried into the storage frame by the rotation of the adhesive cylinder, and the next working part of the sponge block will be pressed into the groove by the pressure plate to reabsorb liquid, during the cutting process, the cut surface of the sponge block will have sponge debris remaining. When the sponge block is used again to clean the film, the sponge debris may fall onto the film, thus affecting the printing quality of the subsequent film. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although the electric push rod can drive the pressure plate to squeeze the sponge block downwards, and the pressure plate will contact the cutter as it continues to move downwards, at which point the failed part of the sponge block will be cut off, and the cut-off sponge block will be carried into the storage frame by the rotation of the adhesive cylinder. At the same time, the next working part of the sponge block will be pressed into the groove by the pressure plate to reabsorb liquid. However, during the cutting process, the cut surface of the sponge block will have sponge debris remaining. When the sponge block is used again to clean the film, the sponge debris may fall onto the film, thus affecting the printing quality of the subsequent film.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dust removal device for chlorine-free printing of high-transparency PETG film, comprising: a base plate, and further comprising: Two fixed plates are symmetrically fixedly connected to the top of the base plate. An adhesive roller is rotatably connected to one side of the two fixed plates. An adhesive roller is positioned above the adhesive roller. Two fixed blocks are fixedly connected vertically to opposite sides of the fixed plates. A movable roller is rotatably connected to one side of the two fixed blocks. Multiple slide strips are slidably connected in a circular array on the outer surface of the movable roller. An installation strip is fixedly connected to one side of each slide strip. A sponge block is detachably installed on one side of each installation strip. Multiple springs are fixedly connected in a circular array at both ends of the outer surface of the movable roller. One end of each of the two springs is symmetrically fixedly connected to the other side of the installation strip. A fixed block is fixedly connected to one side of each fixed block. A synchronous electric telescopic rod is fixedly connected to one side of each fixed block. A push block is fixedly connected to one end of each synchronous electric telescopic rod. A motor is fixedly connected to the other side of each of the two fixed blocks. The output end of the motor is fixedly connected to one end of the movable roller.

[0007] Preferably, a sleeve is fixedly connected to one side of each of the two fixing blocks. The outer surface of the sleeve has an opening groove and a replacement port. A cover plate is slidably connected inside the replacement port. Two screws are symmetrically and movably connected to the outer surface of the cover plate. One end of each screw is symmetrically threaded to the outer surface of the sleeve.

[0008] Preferably, a plurality of atomizing nozzles are fixedly connected at equal intervals on the outer surface of the sleeve, and one end of each atomizing nozzle is fixedly connected to a connecting pipe, wherein the connecting pipe, the plurality of atomizing nozzles and the sleeve are connected in communication.

[0009] Preferably, a groove is provided on one side of the fixing plate two, and a slider is slidably connected inside the groove, and the adhesive roller two is rotatably connected to the two sliders.

[0010] Preferably, a guide rod is fixedly connected to one side of one of the sliders, one of the sliders is slidably connected to the guide rod, a lead screw is rotatably connected to the opposite side of the other slide, the other slider is threadedly connected to the lead screw, and a knob is fixedly connected to one end of the lead screw.

[0011] Preferably, the top of the base plate is symmetrically fixedly connected to two fixing plates, and the opposite sides of the two fixing plates are symmetrically rotatably connected to two limiting rollers.

[0012] Preferably, two sets of fan groups are symmetrically fixedly connected to opposite sides of the two fixed plates.

[0013] Preferably, an unwinding roller is fixedly connected to the top of the base plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a controller to activate a synchronous electric telescopic rod, causing it to extend and move a pusher towards the mounting strip. This pusher applies a force to the mounting strip, causing the slide bar to slide outwards along the inside of the movable roller. The mounting strip and the sponge block are then moved out of the sleeve from the opening slot, allowing the sponge block to adhere to either the first or second adhesion roller. This cleans the first and second adhesion rollers while simultaneously stretching the spring, enabling the sponge block to be cyclically replaced. This eliminates the need for cutting the sponge block, preventing debris from falling onto the high-transparency PETG film and ensuring the printing quality of the high-transparency PETG film.

[0015] This invention allows the screw to be disengaged from the sleeve by hand, enabling the cover plate to be removed and the sponge block replaced. Then, with the help of the screw, the cover plate is installed on the sleeve. In this way, the sleeve and cover plate work together to protect the remaining unused sponge blocks, preventing dust from falling onto them over time and ensuring the cleanliness of the sponge blocks during use.

[0016] This invention allows for manual rotation of a knob, which drives a lead screw to rotate. The lead screw and another slider are connected by a thread, and with the guide rod providing limiting guidance to one slider, the other slider can move up or down along the outer surface of the lead screw. This causes one slider to slide up or down along the outer surface of the guide rod, simultaneously moving the second adhesion roller up or down. By appropriately adjusting the distance between the first and second adhesion rollers, the thickness of the high-transparency PETG film can be adjusted, thus improving the applicability of this device.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Examples, such as Figure 1-4As shown, this utility model provides a dust removal device for chlorine-free printing of high-transparency PETG film, including: a base plate 1, and two fixing plates 2, symmetrically fixedly connected to the top of the base plate 1. An adhesive roller 206 is rotatably connected to one side of the two fixing plates 2, and an adhesive roller 207 is disposed above the adhesive roller 206. Two fixing blocks 3 are fixedly connected vertically to the opposite sides of the fixing plates 2, and a movable roller 401 is rotatably connected to one side of the two fixing blocks 3. Multiple sliding strips 402 are slidably connected in a circumferential array on the outer surface of the movable roller 401, and one side of each sliding strip 402 is fixedly connected to... Mounting strip 403, with a sponge block 404 detachably mounted on one side of mounting strip 403. Multiple springs 405 are fixedly connected in a circumferential array at both ends of the outer surface of movable roller 401. One end of two springs 405 is symmetrically fixedly connected to the other side of mounting strip 403. Fixing block 2 406 is fixedly connected to one side of fixing block 1 3. Synchronous electric telescopic rod 407 is fixedly connected to one side of fixing block 2 406. Push block 408 is fixedly connected to one end of synchronous electric telescopic rod 407. Motor 4 is fixedly connected to the other side of two fixing blocks 1 3. The output end of motor 4 is fixedly connected to one end of movable roller 401.

[0022] Furthermore, such as Figure 1-4 As shown, sleeves 301 are fixedly connected to opposite sides of two fixed blocks 3. An opening groove 306 is provided on the outer surface of the sleeve 301. A replacement port is provided on the outer surface of the sleeve 301. A cover plate 302 is slidably connected inside the replacement port. Two screws 303 are symmetrically and movably connected to the outer surface of the cover plate 302. One end of the two screws 303 is symmetrically threaded to the outer surface of the sleeve 301. By rotating the screws 303 by hand, they can be disengaged from the sleeve 301. At this time, the cover plate 302 can be removed. The sponge block 404 can then be replaced. Then, with the cooperation of the screws 303, the cover plate 302 can be installed on the sleeve 301.

[0023] Furthermore, such as Figure 1-4 As shown, multiple atomizing nozzles 304 are fixedly connected at equal intervals on the outer surface of the sleeve 301. One end of each atomizing nozzle 304 is fixedly connected to a connecting pipe 305. The connecting pipe 305, the multiple atomizing nozzles 304 and the sleeve 301 are connected. An external water pump delivers liquid to the connecting pipe 305 and sprays it onto the surface of the sponge block 404 through the atomizing nozzles 304, thus wetting the sponge block 404.

[0024] Furthermore, such as Figure 1-4 As shown, a groove 201 is provided on one side of the fixed plate 2. A slider 204 is slidably connected inside the groove 201. The adhesive roller 207 is rotatably connected to the two sliders 204. With the above arrangement, the slider 204 can slide up and down along the inside of the groove 201, and synchronously drive the adhesive roller 207 to move up and down.

[0025] Furthermore, such as Figure 1-4 As shown, a guide rod 205 is fixedly connected to one side of one slider 204, and one slider 204 is slidably connected to the guide rod 205. A lead screw 202 is rotatably connected to one side of the other slide groove 201, and another slider 204 is threadedly connected to the lead screw 202. A knob 203 is fixedly connected to one end of the lead screw 202. By turning the knob 203 by hand, the lead screw 202 can be rotated, which can cause the other slider 204 to move up or down along the outer surface of the lead screw 202, and simultaneously drive the second adhesive roller 207 to move up or down, so as to make appropriate adjustments to the distance between the first adhesive roller 206 and the second adhesive roller 207.

[0026] Furthermore, such as Figure 1-4 As shown, two fixing plates 102 are symmetrically fixedly connected to the top of the base plate 1. Two limiting rollers 103 are symmetrically rotatably connected to the opposite side of the two fixing plates 102. The setting of the limiting rollers 103 facilitates the guidance of the high transparency PETG film.

[0027] Furthermore, such as Figure 1-4 As shown, two sets of fan groups 104 are symmetrically fixed to one side of the two fixed plates 102. The fan groups 104 facilitate the air drying process of the high transparency PETG film.

[0028] Furthermore, such as Figure 1-4 As shown, an unwinding roller 101 is fixedly connected to the top of the base plate 1. The unwinding roller 101 facilitates the release of the high-transparency PETG film and enables the subsequent printing device to print the high-transparency PETG film. Finally, the film is wound up by the rewinding roller.

[0029] Working Principle: In use, by manually turning knob 203, the lead screw 202 rotates. Then, under the action of the threaded connection between the lead screw 202 and another slider 204, and with the guide rod 205 limiting and guiding one of the sliders 204, the other slider 204 can move up or down along the outer surface of the lead screw 202. This causes one slider 204 to slide up or down along the outer surface of the guide rod 205, simultaneously driving the second adhesion roller 207 to move up or down. By appropriately adjusting the distance between the first adhesion roller 206 and the second adhesion roller 207, the thickness of the high-transparency PETG film can be appropriately adjusted, thereby improving the applicability of this device. Liquid is supplied to the connecting pipe 305 by an external water pump and atomized. The nozzle 304 sprays water onto the surface of the sponge block 404, wetting it. Then, the controller starts the motor 4, causing its output shaft to rotate the movable roller 401, slide bar 402, mounting bar 403, and sponge block 404, moving the wet sponge block 404 to the opening slot 306. At this point, the controller starts the synchronous electric telescopic rod 407, extending it and causing the pusher block 408 to move towards the mounting bar 403, applying a thrust to it. This causes the slide bar 402 to slide outwards along the inside of the movable roller 401, moving the mounting bar 403 and sponge block 404 out of the sleeve 301 from the opening slot 306. The sponge block 404 then adheres to the first adhesion roller 206 or the second adhesion roller 207. 6. Cleaning is performed on the adhesion roller 207, and the spring 405 is stretched simultaneously. The sponge block 404 is cyclically replaced, eliminating the need to cut off the sponge block 404. This prevents residual debris from falling onto the high-transparency PETG film, thus ensuring the printing quality of the high-transparency PETG film. Under the reset force of the spring 405, when the synchronous electric telescopic rod 407 retracts, releasing the pushing force of the pusher block 408 on the mounting strip 403, the mounting strip 403 and the sponge block 404 can return to the inside of the sleeve 301 under the reset force of the spring 405. By manually turning the screw 303, it can be disengaged from the sleeve 301, at which point the cover plate 302 can be removed. The sponge block 404 is replaced, and then, with the cooperation of the screw 303, the cover plate 302 is installed on the sleeve 301. In this way, with the cooperation of the sleeve 301 and the cover plate 302, the remaining unused sponge blocks 404 can be covered and protected to prevent dust from falling onto the sponge blocks 404 after long-term storage, thereby ensuring the cleanliness of the sponge blocks 404 during use. The unwinding roller 101 facilitates the release of the high-transparency PETG film, and the limiting roller 103 guides the high-transparency PETG film. The fan group 104 facilitates the air drying of the high-transparency PETG film, and the high-transparency PETG film is printed by the subsequent printing device. Finally, it is wound up by the take-up roller.
