Description

Technical Field

[0001] This utility model relates to a glue removal device, specifically a glue removal device for label printing, and belongs to the field of glue removal technology. Background Technology

[0002] A label removal device is a specialized piece of equipment for precisely removing adhesive layers from specific areas of label materials. It is mainly used in scenarios where it is necessary to remove self-adhesive, hot melt adhesive, and other adhesives from specific areas of the label (such as label edges, windowed areas, or reserved bonding areas). Its working principle is usually to process the preset adhesive removal area after the adhesive layer is applied to the label face material (such as paper or film) and before the release paper (backing paper) is laminated, through mechanical scraping, laser burning, high-pressure airflow purging, or solvent dissolution. Mechanical scraping devices are suitable for situations where the adhesive layer is semi-dry (with a certain hardness but still scrapable) or in areas where the adhesive layer is relatively thick. The scraper can remove excess adhesive layer locally by physical scraping. For example, the scraper can quickly handle simple defects such as adhesive overflow at the label edges or local adhesive layer protrusions.

[0003] However, in existing mechanical scraping adhesive removal devices, when scraping a local area of ​​the adhesive layer with a scraper, adhesive residue is easily left on the label surface due to the adhesive layer's stickiness. If the adhesive residue is not cleaned up in time, it can easily adhere to the scraper or label again, resulting in incomplete adhesive removal and poor effect, thus affecting the efficiency and quality of local adhesive removal. Utility Model Content

[0004] The purpose of this invention is to provide a glue removal device for label printing in order to solve the above-mentioned problems. By setting suction nozzles on both sides of the squeegee to clean glue debris in time, and by using a displacement sensor to precisely control the position of the squeegee, the device effectively avoids glue residue and secondary adhesion, thereby improving the efficiency, cleanliness and accuracy of local glue removal and ensuring label quality.

[0022] 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.

[0023] Please see Figures 1-6 As shown, a de-adhesive device for label printing includes a mounting frame 1, on which two sets of conveying assemblies 2 are mounted. A face material 3 is provided on one set of conveying assemblies 2 located at the bottom of the mounting frame 1. A scraper 5 is mounted on the mounting frame 1 via a drive assembly 4. The scraper 5 is located above the face material 3. A cleaning assembly 6 is mounted on the mounting frame 1. The cleaning assembly 6 includes a dust collection box 601. The dust collection box 601 is mounted on the mounting frame 1. Two hoses 602 are provided on the side of the dust collection box 601 facing the scraper 5. A suction nozzle 603 is fixedly connected to the bottom end of the hose 602. The two suction nozzles 603 are respectively installed on both sides of the scraper 5. A displacement sensor 7 is mounted on the drive assembly 4.

[0024] As a technical optimization of this utility model, elastic sleeves 604 are fixedly connected to both sides of the scraper 5, and the suction nozzle 603 is engaged with the elastic sleeves 604. A dust pump 605 is installed on the other side of the dust collection box 601. By engaging the suction nozzle 603 with the elastic sleeves 604, the suction nozzle 603 can be fixed quickly, making the installation and disassembly work more convenient.

[0025] As a technical optimization of this utility model, the drive assembly 4 includes a slide rail 401. The slide rail 401 is fixedly connected to the dust collection box 601. A lead screw 402 is rotatably connected inside the slide rail 401. A slider 403 is threadedly connected to the lead screw 402. The slider 403 is slidably connected to the slide rail 401. A first motor 406 is installed on the side of the mounting bracket 1 facing away from the surface material 3. The output shaft of the first motor 406 is fixedly connected to the lead screw 402. A mounting base 404 is slidably connected to the bottom end of the slider 403. A rotating rod 405 is rotatably connected to the mounting base 404. A hydraulic rod 407 is rotatably connected between the mounting base 404 and the rotating rod 405. A rotating sleeve 408 is rotatably connected to the bottom end of the rotating rod 405. The rotating sleeve 408 engages with the scraper 5. A driven gear 409 is fixedly connected to the rotating shaft at the top of the rotating sleeve 408. A second motor 411 is fixedly connected to the rotating rod 405. A drive gear 410 is fixedly connected to the output shaft of the second motor 411. The drive gear 410 meshes with the driven gear 409. The connection is achieved through the slide rail 401 and the lead screw 4. 02. The slider 403 is moved to adjust the horizontal position of the scraper 5. The angle of the rotating rod 405 is adjusted by the hydraulic rod 407 to control the contact force between the scraper 5 and the surface material 3. The angle of the scraper 5 is adjusted by the engagement of the rotating sleeve 408 with the scraper 5 and the rotation of the rotating sleeve 408. Thus, the position, force and angle of the scraper 5 are precisely controlled to complete the precise removal of glue. The cross-section of the slider 403 is T-shaped, which can effectively prevent the slider 403 from falling off the slide rail 401 when sliding. The cross-section of the top of the scraper 5 is T-shaped. The structure facilitates quick engagement and positioning of the scraper 5 and the rotating sleeve 408, ensuring stable installation and convenient assembly and disassembly. A spring 413 is fixedly connected between the slider 403 and the mounting base 404. A slide rod 414 is installed on the mounting base 404, and the slide rod 414 is slidably connected to the slider 403. The spring 413 can buffer the pressure when the scraper 5 contacts the surface material 3, avoiding hard contact that could damage the surface material 3 or the scraper 5. The slide rod 414 guides the mounting base 404 to slide smoothly, preventing it from slipping off, thereby ensuring the stability and safety of the glue scraping process.

[0026] As a technical optimization of this utility model, the rotating sleeve 408 is threadedly connected to a knob 412. The end of the knob 412 is inserted into the scraper 5. After the knob 412 is tightened through the threaded connection, its end is inserted into the scraper 5 to achieve fixation. This can ensure that the scraper 5 is installed firmly and can be quickly disassembled and replaced by loosening, so as to facilitate the adjustment or replacement of scrapers 5 of different specifications according to needs.

[0027] As a technical optimization of this utility model, the displacement sensor 7 is fixedly connected to the slide rail 401. A set of conveying components 2 located at the top of the mounting frame 1 is provided with a base paper 8. A set of composite rollers 9 are installed on the mounting frame 1. The ends of the face material 3 and the base paper 8 abut against the composite rollers 9. The base paper 8 is conveyed by the conveying components 2 at the top of the mounting frame 1 and pressed together with the face material 3 after the glue has been removed by the composite rollers 9, so that the two are tightly bonded to form a complete label material, ensuring the smooth progress of subsequent processes.

[0028] In use, the device is first started. Two sets of conveying components 2, each consisting of multiple conveying rollers and tension adjusting rollers, simultaneously convey the face material 3 (the label substrate to be de-adheded) and the backing paper 8. The face material 3 is first conveyed to below the scraper 5. According to the de-adhesion position requirement, the first motor 406 drives the lead screw 402 to rotate, causing the slider 403 to move along the slide rail 401. Combined with the positioning feedback from the displacement sensor 7, the scraper 5 is precisely aligned with the target adhesive layer area on the face material 3. Subsequently, the hydraulic rod 407 extends and retracts to adjust the angle of the rotating rod 405. The degree of contact between the scraper 5 and the face material 3 is controlled, enabling the scraper 5 to perform adhesive scraping operations on adhesive layers and face paper of different thicknesses. When the scraping angle needs to be adjusted, the second motor 411 is started through the control terminal. The rotation of the second motor 411 drives the drive gear 410 to rotate, thereby driving the rotating sleeve 408 to rotate through the meshing of the drive gear 410 and the driven gear 409, which in turn drives the scraper 5 to adjust the scraping angle to ensure further adhesion and adhesive removal requirements. During the adhesive removal operation of the scraper 5, the scraper 5 is connected to the rotating rod 405 and the mounting base 4. When the spring 413 retracts, the spring 413 between the slider 403 and the mounting base 404 buffers the pressure of the scraper 5, preventing damage to the surface material 3. The slide bar 414 prevents the mounting base 404 from slipping off the slider 403, thus ensuring a stable and efficient adhesive removal process. When the scraper 5 is damaged or needs to be replaced with a scraper 5 better suited to the adhesive removal requirements, loosening the knob 412 allows it to be removed from the rotating sleeve 408. After replacement, the "T"-shaped structure at the tip of the scraper 5 engages with the rotating sleeve 408, quickly completing the initial positioning of the scraper 5. Then, tighten the knob 412 again to complete the installation of the scraper 5; during the scraping process, start the dust pump 605 to generate negative pressure in the dust collection box 601, which is transmitted to the suction nozzle 603 through the hose 602 on the side wall, so that the suction nozzle 603 enters the working state and sucks away the scraped glue debris in real time to avoid secondary adhesion; then the surface material 3 that has completed partial glue removal continues to be conveyed and enters the composite roller 9 together with the backing paper 8 sent by the top conveying component 2. After being pressed by the composite roller 9, a complete label material is formed and finally conveyed to the next process.
