[0002] In the field of packaging film production, glue coating is a key process step, and its quality directly affects the use performance and product quality of packaging films.

[0003] Currently, when using a packaging film glue coating device to process packaging films, during the use of the glue coating device, the glue in the glue storage box is coated on the packaging film by the rotation of the glue coating roller. After the glue coating on the surface of the packaging film is completed, it is difficult to effectively clean the glue remaining on the surface of the glue coating roller. As production continues, the remaining glue is prone to curing and accumulation, which will not only cause the surface of the glue coating roller to be uneven, but also cause problems such as uneven glue distribution and impurity spots on the packaging film during subsequent coating. In order to ensure the coating quality, the remaining glue needs to be manually cleaned regularly by personnel, which is time-consuming and laborious.

[0004] Therefore, a glue coating device for packaging films is proposed. Content of the Utility Model

[0025] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a glue coating device for packaging film includes a base 1 and a plastic scraper 6. A glue storage component 2 is arranged on the top surface of the base 1, and a glue coating component 3 for coating glue on the surface of the packaging film is arranged on the top surface of the base 1. A moving component 4 for cleaning the surface of the coating roller is arranged on the surface of the glue coating component 3. An installation frame 5 for installing the plastic scraper 6 is arranged on the surface of the moving component 4. A locking nut 7 is threadedly connected to the installation frame 5, and an installation component 8 for installing the plastic scraper 6 on the installation frame 5 is arranged on the surface of the plastic scraper 6; specifically, for this glue coating device for packaging film, the glue storage component 2 is provided for storing glue. The glue coating component 3 is used in cooperation with an external packaging film conveying structure, so that the surface of the packaging film fits the surface of the coating roller, and the glue coating component 3 coats the glue on the surface of the packaging film. The installation frame 5 is provided for the installation and connection of the plastic scraper 6. The installation component 8 on the plastic scraper 6 is used in cooperation with the locking nut 7, so that the plastic scraper 6 is fixedly installed on the installation frame 5 by means of plug-in connection, enabling the plastic scraper 6 to be conveniently disassembled and assembled. The moving component 4 can drive the plastic scraper 6 to displace, and thus the distance between the plastic scraper 6 and the coating roller can be adjusted. During the glue coating process, by adjusting the distance between the plastic scraper 6 and the coating roller, the glue on the surface of the coating roller can be made more uniform, improving the glue coating effect. After the glue coating is completed, the moving component 4 drives the plastic scraper 6 to fit the surface of the coating roller. At this time, the plastic scraper 6 can scrape off the residual glue on the surface of the coating roller, completing the cleaning work of the surface of the coating roller.

[0026] As Figure 2 , Figure 4 shown, the glue storage component 2 includes a glue storage box 201. The glue storage box 201 is fixedly connected to the top surface of the base 1. A heating tube structure 202 is arranged on the glue storage box 201, and a glue discharge pipe 203 is arranged on the surface of the glue storage box 201; specifically, the glue storage box 201 serves as a storage container for glue, providing continuous glue supply for the coating process. The heating tube structure 202 is a straight heating tube structure. The heating tube is linear, and heating elements such as resistance wires are arranged along the axial direction of the straight tube, with an insulating and heat-conducting material wrapped on the outside and a metal protection sleeve on the outermost layer. The heating tube structure 202 keeps the glue at an appropriate temperature by heating, preventing the glue from becoming thick or solidifying due to temperature reduction, and ensuring that the glue can flow smoothly and be evenly coated. The glue discharge pipe 203 can discharge the excess glue in the glue storage box 201 to the outside.

[0027] As Figure 1 , Figure 2As shown, the glue - applying assembly 3 includes a bracket 301. The top surface of the base 1 is fixedly connected to the bracket 301. A motor - driving structure 302 is arranged on the bracket 301. A glue - applying roller structure 303 is rotatably connected to the bracket 301, and the output end of the motor - driving structure 302 is fixedly connected to the glue - applying roller structure 303. Specifically, the bracket 301 serves as the basic framework of the glue - applying assembly 3 and is fixed on the base 1, providing a stable installation platform for the motor - driving structure 302 and the glue - applying roller structure 303. The motor - driving structure 302 serves as the power source and drives the rotation of the glue - applying roller structure 303 through the output shaft to achieve the glue - coating action. The motor - driving structure 302 can adjust the motor speed through a speed - regulating device such as a frequency converter, thereby controlling the linear speed of the glue - applying roller to adapt to different packaging film materials and coating process requirements. The packaging - film conveying structures on both sides of the glue - applying roller structure 303 convey the packaging film by conveying rollers. The conveying rollers are arranged in pairs, one above the other, and are respectively located in front of and behind the glue - applying roller structure 303, so that the surface of the packaging film fits the surface of the glue - applying roller structure 303. The surface of the glue - applying roller structure 303 receives the glue from the glue storage box 201 and transfers the glue to the surface of the packaging film through rotation.

[0028] As Figure 2 , Figure 3As shown, the moving component 4 includes a first mounting block 401. The surface of the bracket 301 is fixedly connected to the first mounting block 401. A motor 402 is provided on the first mounting block 401. The output end of the motor 402 is fixedly connected to a threaded rod 403. A moving block 404 is threadedly connected to the surface of the threaded rod 403, and the mounting frame 5 is fixedly connected to the moving block 404. The surface of the bracket 301 is fixedly connected to a second mounting block 405. A sliding rod 406 is fixedly connected to the surface of the second mounting block 405. A slider 407 is movably sleeved on the surface of the sliding rod 406, and the mounting frame 5 is fixedly connected to the slider 407. Specifically, the plastic blade 6 is driven by the moving component 4 to fit the surface of the glue application roller structure 303. When the glue application roller rotates, the residual glue on the surface of the glue application roller can be effectively scraped off, ensuring the cleanliness of the glue application roller. At the same time, during the glue application process, by changing the distance between the plastic blade 6 and the glue application roller structure 303, the amount of glue adhered to the surface of the glue application roller can be limited. When the distance is small, more glue will be scraped off, making the glue transferred to the packaging film by the glue application roller thinner; when the distance is large, more glue will be retained on the glue application roller, and the glue transferred to the packaging film will be thicker, thereby accurately controlling the glue application thickness of the packaging film. The motor drive structure 302 in the glue application component 3 can achieve precise control of the rotation speed of the glue application roller. A stable rotation speed can make the distribution of the glue on the surface of the glue application roller more regular, reducing the change in the amount of glue adhered due to the rotation speed fluctuation; the plastic blade 6 scrapes off the excess glue, playing a role in quantitative control. Even if the glue accumulates locally or is unevenly distributed due to the change in the center of gravity of the glue application roller during rotation, the plastic blade 6 can scrape it off in time to ensure a stable amount of glue adhered; the surface of the glue application roller structure 303 can be specially treated, such as machining uniform micro-grooves or textures. When the glue application roller rotates, these structures can accommodate and limit the glue to a certain extent, making the glue distribution on the surface more uniform and reducing the problem of uneven glue flow caused by the change in the center of gravity. When the glue application roller structure 303 rotates, the plastic blade 6 can scrape off the excess glue on its surface, making the glue evenly distributed on the surface of the glue application roller. Adjusting the distance can ensure an appropriate scraping amount, avoiding the situation of local glue accumulation or deficiency, and making the glue application on the entire surface of the packaging film more uniform. Turning on the motor 402 in the moving component 4, the motor 402 drives the threaded rod 403 to rotate, causing the moving block 404 to move on the threaded rod 403 and the slider 407 to slide on the sliding rod 406, thereby driving the mounting frame 5 and the plastic blade 6 to move and adjusting the distance between the plastic blade 6 and the glue application roller structure 303.

[0029] As Figure 3As shown, the installation component 8 includes a plug-in block 801. The surface of the plastic scraping blade 6 is fixedly connected with the plug-in block 801. The surface of the plug-in block 801 is provided with an installation hole 802, and the lock nut 7 is threadedly connected with the installation hole 802. Specifically, the surface of the plug-in block 801 is provided with an installation hole 802, and the lock nut 7 is threadedly connected with the installation hole 802, realizing the stable installation of the plastic scraping blade 6 on the installation frame 5. The plastic scraping blade 6 is plugged and connected to the installation frame 5 through the installation component 8. After the plug-in block 801 is plugged into the interior of the installation frame 5, the lock nut 7 is screwed onto the installation frame 5, and the plastic scraping blade 6 can be fixedly connected to the installation frame 5. When it is necessary to disassemble the plastic scraping blade 6, only the lock nut needs to be screwed out, and the plastic scraping blade 6 can be pulled outwards for replacement. That is, when the plastic scraping blade 6 adheres to glue and affects normal use after increasing the scraping times, it is convenient to replace it.

[0030] As Figure 4 As shown, a liquid level sensor is arranged inside the glue storage box 201. The liquid level sensor is electrically connected to an external controller, and the controller is electrically connected to an alarm device. Specifically, when the liquid level sensor detects that the glue liquid level in the glue storage box 201 is lower than the set value, the liquid level sensor transmits a signal to the controller, and the controller controls the alarm device to emit an alarm to remind the operator to replenish the glue liquid in time.

[0031] In summary: Device installation and preparation: Install the first mounting block 401 and the second mounting block 405 of the moving component 4 on the bracket 301, install the motor 402 on the first mounting block 401, connect the threaded rod 403 and the moving block 404, install the sliding rod 406 and the slider 407 on the second mounting block 405, and fixedly connect the installation frame 5 to the moving block 404 and the slider 407. Install the plastic scraping blade 6 on the installation frame 5 through the installation component 8 and tighten and fix it with the lock nut 7. Add glue liquid into the glue storage box 201 and turn on the heating tube structure 202 for heating according to the characteristics of the glue liquid.

[0032] Glue coating process: Place the packaging film on the external conveying structure so that the surface of the packaging film fits the surface of the glue coating roller structure 303. Turn on the motor driving structure 302 to drive the rotation of the glue coating roller structure 303. The bottom of the glue coating roller structure 303 contacts the glue in the glue storage box 201. As the glue coating roller structure 303 rotates, the glue is coated on the surface of the packaging film. During this process, according to the required thickness of the glue, turn on the motor 402 in the moving component 4. The motor 402 drives the rotation of the threaded rod 403, causing the moving block 404 to move on the threaded rod 403 and the slider 407 to slide on the slide rod 406, thereby driving the installation frame 5 and the plastic scraper 6 to move, adjusting the distance between the plastic scraper 6 and the glue coating roller structure 303, and making the glue on the surface of the glue coating roller structure 303 more uniform.

[0033] Glue coating roller cleaning process: After the glue coating on the surface of the packaging film is completed, continue to keep the glue coating roller structure 303 rotating, drive the plastic scraper 6 to move through the moving component 4, make the plastic scraper 6 fit the surface of the glue coating roller structure 303. As the glue coating roller structure 303 rotates, the plastic scraper 6 scrapes off the residual glue on the surface of the glue coating roller structure 303, completing the cleaning work of the glue coating roller surface. After the cleaning is completed, the plastic scraper 6 can be adjusted to separate from the glue coating roller structure 303 according to needs for the next coating operation.
