Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive paper coating technology, and more specifically, it relates to a dust removal device for self-adhesive paper coating production. Background Technology

[0002] Self-adhesive paper, also known as pressure-sensitive adhesive paper, is a composite material consisting of a face paper and a backing paper. The face paper is typically made of paper, film, or a special material, with an adhesive coating on the back. The backing paper is coated with a silicone protective paper. After peeling off the backing paper, it can be directly adhered to the object being applied. During the coating process, self-adhesive paper easily attracts dust and paper fibers. If not handled promptly, these particles can become embedded in the adhesive layer, creating visible defects such as raised or sunken areas, affecting product quality.

[0003] To address the aforementioned issues, patent publication number "CN222267683U" discloses a self-adhesive label coating device with dust removal function. By employing the coordinated use of a hydraulic cylinder, rack, threaded rod, gears, fine brush, dust removal fan, dust collection box, suction fan, and dust discharge box, the device enhances the dust removal and cleaning of the adhesive-receiving surface of the label during the coating process. This reduces dust particles on the adhesive surface, helps maintain the stability of the adhesive viscosity after coating, increases the smoothness of the coated label surface, and prevents dust particles from mixing with the adhesive, thus avoiding unevenness and improving the practicality of the label. Ultimately, this contributes to improving the quality of the label after production.

[0004] However, the above-mentioned device still has the following shortcomings: 1. It is not suitable for continuous adhesive paper coating and cleaning. The dust removal fan and fine brush can only remove large particles of impurities and dust. However, the adhesive paper is more likely to electrostatically attract some small particles, such as paper fibers, during operation. The dust removal effect of physical sweeping and airflow adsorption alone is not good, resulting in some dust residue; 2. The fine brush moves in a straight line along the threaded rod to remove dust. With the label conveying, there are blind spots in cleaning. Incomplete cleaning will lead to the edge peeling or unevenness after the adhesive is applied. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dust removal device for the production of self-adhesive paper coating, which adds a dust removal box at the paper feeding end of the coating roller. The dust removal box adopts a multi-stage dust removal design, which improves cleaning efficiency and cleaning effect.

[0006] The aforementioned dust removal equipment for self-adhesive paper coating production includes a coating and laminating box, a coating roller rotatably connected inside the coating and laminating box, and a dust removal box located at the paper inlet end of the coating roller. The dust removal box is characterized by: a drive roller rotatably connected to the side of the dust removal box near the paper inlet end; a dust removal brush plate fixedly connected inside the dust removal box, with the end of the dust removal brush plate abutting against the drive roller; a dust-adhesive roller and a transfer roller rotatably connected to the side of the dust removal box near the paper outlet end, with the transfer roller contacting the dust-adhesive roller; and an ion fan located between the drive roller and the dust-adhesive roller.

[0007] Preferably, the dust collection box includes an outer shell, with a paper outlet at the top and a paper inlet at the bottom. A ventilation filter corresponding to the ion fan is fixedly connected to the side of the outer shell. A flip cover is rotatably connected to the outer shell via a hinge. The flip cover corresponds to the transfer roller, and the two ends of the flip cover are fixedly connected with buckles that cooperate with the outer shell.

[0008] Preferably, the two ends of the outer shell are respectively fixedly connected to a self-tightening quick-release mechanism that cooperates with the transfer roller. The self-tightening quick-release mechanism includes a fixed frame, a bearing seat is slidably connected inside the fixed frame, a bearing is provided inside the bearing seat, a screw is fixedly connected to the side of the bearing seat away from the dust roller, the screw passes through the fixed frame, and a spring is sleeved on the screw. The two ends of the spring abut against the bearing seat and the inner end face of the fixed frame respectively, and a nut that is threadedly engaged with the screw is provided outside the fixed frame.

[0009] Preferably, a bushing is fixedly connected inside the inner ring of the bearing. The bushing has a hexagonal hole that mates with the end of the transfer roller. A movable plate is slidably connected inside the hexagonal hole. A spring is provided between the movable plate and the inner end face of the bushing.

[0010] Preferably, the dust removal brush plate includes a mounting plate, on which a first T-shaped groove and a second T-shaped groove are provided vertically. The first T-shaped groove is provided with a plurality of flexible scrapers, and the second T-shaped groove is provided with a plurality of brushes. T-shaped sliders are fixed on the flexible scrapers and the brushes respectively.

[0011] Preferably, the flexible scraper and the brush at both ends are provided with T-shaped fixing blocks, which are disposed in the corresponding first T-shaped groove and second T-shaped groove, and fastening bolts are threadedly connected to the T-shaped fixing blocks.

[0012] Preferably, the front end of the adhesive coating box is provided with a swing seat, the middle part of the swing seat is rotatably connected to the adhesive coating box, the upper end of the swing seat is fixedly connected to an adhesive coating mechanism, the adhesive coating mechanism cooperates with an adhesive coating roller, and the lower end of the swing seat is rotatably connected to a telescopic mechanism, which is fixedly connected to the adhesive coating box.

[0013] Preferably, the front end of the adhesive coating mechanism is provided with an adhesive top paper unwinding roller, and the rear end of the adhesive coating and laminating box is rotatably connected with an adhesive bottom paper unwinding roller and a take-up roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A dust collection box is added to the paper feed end of the coating roller. The dust collection box adopts a multi-stage dust collection design, which improves cleaning efficiency and cleaning effect. Among them, the dust collection brush plate forms a double-layer filter through a plate brush and a flexible scraper to remove contaminants of different particle sizes in stages; the ion fan is the second stage of dust collection, which neutralizes the static electricity on the surface of the self-adhesive paper, eliminates the electrostatic adsorption force of dust, and makes it easier for small particles to be captured by the subsequent sticking roller, solving the problem that traditional mechanical dust collection is difficult to handle electrostatic adsorption impurities; the sticking roller and the transfer roller work together to form a third stage of dust collection. The sticking roller directly adheres to residual fibers and other impurities, and the transfer roller transfers the contaminants on the surface of the sticking roller in real time through a tearable adhesive paper, avoiding secondary pollution and forming a self-cleaning cycle to continuously maintain the dust collection effect.

[0016] 2. Self-tightening quick-release mechanisms are added to both ends of the transfer roller. The self-tightening quick-release mechanisms automatically compensate for the diameter change of the transfer roller caused by the consumption of adhesive paper through elastic force, ensuring that it is always in close contact with the dust removal roller and avoiding dust removal failure due to increased gap.

[0017] 3. The hexagonal shaft at the end of the transfer roller is quick-connected to the bushing. When replacing, it can be disassembled by simply squeezing the movable plate on one side, achieving tool-free quick replacement and improving maintenance convenience. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 10As shown, a dust removal device for self-adhesive paper coating production includes a coating and laminating box 2, which serves as the main frame. A coating roller 201 is rotatably connected inside the box, and the coating roller 201 is connected to a power mechanism that drives it to rotate. This structure is existing technology. A dust removal box 6 is located at the paper inlet end of the coating roller 201. The dust removal box 6 performs multi-stage dust removal on the self-adhesive paper before coating, ensuring the surface of the paper is clean before coating. A drive roller 7 is rotatably connected to the side of the dust removal box 6 near the paper inlet end. The drive roller 7 is a non-powered roller that rotates with the coating roller 201 and the paper being conveyed. This rotation drives the self-adhesive paper into the dust removal box 6. A dust removal brush plate 8 is fixedly connected inside the dust removal box 6. The end of the dust removal brush plate 8 abuts against the drive roller 7. During the paper conveying process, the dust removal brush plate 8 effectively contacts the paper surface for preliminary dust removal, removing large particles of impurities. A dust collection box 6 is rotatably connected to a dust-adhesive roller 11 and a transfer roller 10 near the paper output end. The transfer roller 10 is in contact with the dust-adhesive roller 11. An ion fan 9 is installed between the drive roller 7 and the dust-adhesive roller 11. The ion fan 9 is existing technology. It generates positive and negative ions to neutralize the static electricity on the self-adhesive paper, causing the dust adsorbed on the paper surface to lose its electrostatic attraction, making it easier to remove. It also avoids the influence of static electricity on subsequent gluing processes. The dust-adhesive roller 11 is in direct contact with the paper, adhering to residual paper fibers and other small impurities. The transfer roller 10 is existing technology. It has a tearable adhesive paper on it, which can transfer the small impurities adhering to the surface of the dust-adhesive roller 11 to the transfer roller 10, ensuring that the surface of the dust-adhesive roller 11 is clean and that the self-adhesive paper will not be re-contaminated with dust when it is transferred on the dust-adhesive roller 11. The transfer roller 10 can be quickly cleaned by tearing off the adhesive paper on top of it.

[0033] like Figure 4 and Figure 5 As shown, the dust collection box 6 includes an outer shell 601. The top of the outer shell 601 has a paper outlet 602, and the bottom of the outer shell 601 has a paper inlet 607. The paper inlet 607 and the paper outlet 602 form the inlet and outlet channels for the self-adhesive paper, ensuring that the paper can pass smoothly through the dust collection area. A ventilation filter 606 corresponding to the ion fan 9 is fixedly connected to the side of the outer shell 601. The ventilation filter 606 provides a clean air inlet channel for the ion fan, ensuring that the blown ion air is not contaminated by external dust. A flip cover 603 is rotatably connected to the outer shell 601 via a hinge 605. The flip cover 603 corresponds to the transfer roller 10. The flip cover 603 not only facilitates the maintenance and replacement of the internal transfer roller 10 but also seals the box during operation to prevent dust from overflowing. Fasteners 604 that cooperate with the outer shell 601 are fixedly connected to both ends of the flip cover 603. The latch 604 serves as a limit and also secures the flip cover 603, ensuring that the inside of the dust collection box 6 is in a relatively closed working environment.

[0034] Both ends of the outer casing 601 are respectively fixedly connected to a self-tightening quick-release mechanism 12 that cooperates with the transfer roller 10, such as... Figure 9 and Figure 10 As shown, the self-tightening quick-release mechanism 12 includes a fixed frame 1201, a bearing seat 1202, and a bushing 1203. Slide rails are fixed on both sides of the fixed frame 1201, and the two slide rails are slidably connected to the bearing seat 1202. The bearing seat 1202 has grooves at both ends that cooperate with the slide rails. A bearing is installed inside the bearing seat 1202 to support the transfer roller 10. A screw 1206 is fixedly connected to the side of the bearing seat 1202 away from the dust roller 11. The screw 1206 passes through the fixed frame 1201, and a spring 1205 is sleeved on the screw 1206. The two ends of the spring 1205 abut against the inner end faces of the bearing seat 1202 and the fixed frame 1201, respectively. A nut 1207 that is threadedly engaged with the screw 1206 is provided outside the fixed frame 1201. The bearing housing 1202 is slidable within the fixed frame 1201. In conjunction with the spring 1205, it automatically adjusts the installation position of the transfer roller 10, ensuring that the transfer roller 10 remains in close contact with the dust roller 11 even as the surface adhesive paper decreases. The nut 1207 can adjust the preload of the spring 1205 as needed. The self-tightening quick-release mechanism 12 automatically tightens the bearing housing 1202 through the elastic force of the spring 1205.

[0035] A bushing 1203 is fixedly connected to the inner ring of the bearing. The bushing 1203 has a hexagonal hole 1204 that mates with the end of the transfer roller 10. The hexagonal hole 1204 is a hexagonal prism hole. A movable plate 1209 is slidably connected within the hexagonal hole 1204. A second spring 1208 is positioned between the movable plate 1209 and the inner end face of the bushing 1203. Both ends of the second spring 1208 are fixedly connected to the movable plate 1209 and the inner end face of the bushing 1203, respectively. Hexagonal shafts that mate with the hexagonal holes 1204 are fixed at both ends of the transfer roller 10. Using the movable plate 1209 and the second spring 1208, the transfer roller 10 can be quickly disassembled and replaced with a new one.

[0036] like Figure 6 and Figure 7As shown, the dust removal brush plate 8 includes a mounting plate, with both ends fixedly connected to the outer casing 601. Multiple support blocks are fixed between the bottom of the mounting plate and the inner bottom of the outer casing 601 to assist in supporting the mounting plate. The mounting plate has a first T-shaped groove 801 and a second T-shaped groove 802 arranged vertically, providing mounting tracks for the flexible scraper 804 and the brush 805. Multiple flexible scrapers 804 are arranged side-by-side and tightly fitted within the first T-shaped groove 801. Multiple brushes 805 are arranged side-by-side and tightly fitted within the second T-shaped groove 802. T-shaped sliders matching the corresponding first T-shaped groove 801 and second T-shaped groove 802 are fixed to the flexible scrapers 804 and brushes 805. The brushes 805 are used to clean larger dust particles from the surface of the self-adhesive paper, while the flexible scrapers 804 can scrape away fine dust residue from the surface of the self-adhesive paper.

[0037] Multiple flexible scrapers 804 or brushes 805 form a complete scraper or brush, which makes it easier to install and maintain. When some of the flexible scrapers 804 or brushes 805 are severely worn, only the corresponding flexible scraper 804 or brush 805 needs to be replaced, without replacing the entire scraper, thus saving costs.

[0038] The flexible scraper 804 and brush 805 at both ends are provided with T-shaped fixing blocks 803. The T-shaped fixing blocks 803 are disposed in the corresponding first T-shaped grooves 801 and second T-shaped grooves 802, and fastening bolts 8031 ​​are threadedly connected to the T-shaped fixing blocks 803. By tightening the fastening bolts 8031, the T-shaped fixing blocks 803 are fixed to the corresponding first T-shaped grooves 801 and second T-shaped grooves 802, which serves as a limiting function to position the flexible scraper 804 and brush 805.

[0039] Example 2:

[0040] A dust removal device for adhesive coating production of self-adhesive paper includes a swing seat at the front end of a coating and laminating box 2. The middle of the swing seat is rotatably connected to the coating and laminating box 2. A coating mechanism 3 is fixedly connected to the upper end of the swing seat, and the coating mechanism 3 cooperates with a coating roller 201. A telescopic mechanism is rotatably connected to the lower end of the swing seat, and the telescopic mechanism is fixedly connected to the coating and laminating box 2. By controlling the swing angle of the swing seat through the telescopic mechanism, the relative position of the coating mechanism 3 and the coating roller 201 can be adjusted to achieve precise coating.

[0041] The adhesive coating mechanism 3 has a self-adhesive face paper unwinding roller 1 at its front end, and a self-adhesive backing paper unwinding roller 4 and a take-up roller 5 rotatably connected to the rear end of the adhesive coating and laminating box 2. The self-adhesive face paper unwinding roller 1 at the front end is used to place the face paper to be coated, while the self-adhesive backing paper unwinding roller 4 and the take-up roller 5 at the rear end are respectively responsible for supplying the backing paper and winding up the finished product after lamination, forming a complete adhesive coating production process. Everything else is the same as in Example 1.

[0042] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0043] Working principle:

[0044] In use, the face paper is unwound from the self-adhesive face paper unwinding roller 1, enters the dust collection box 6 through the paper inlet 607, and is then conveyed forward by the drive roller 7. During the conveying process, the brushes 805 on the dust collection brush plate 8 first sweep away larger dust particles on the face paper surface, and then the flexible scraper 804 further scrapes away the remaining fine dust. When the face paper passes through the ion fan 9, the ion wind generated by the ion fan 9 neutralizes the static electricity on the face paper surface, making it easier for small impurities to detach from the face paper. Next, the face paper is conveyed to the adhesive roller 11, which removes any small impurities that may remain on the face paper surface. At the same time, the transfer roller 10 transfers the small impurities on the adhesive roller 11 to the adhesive roller 11 in a timely manner, ensuring that the adhesive roller 11 contacts the face paper in a clean state and preventing the face paper from being contaminated again. After dust removal, the face paper leaves the dust removal box 6 from the paper outlet 602 and enters the coating roller 201 in the coating and laminating box 2. Under the action of the coating mechanism 3 and the coating roller 201, the coating process is completed. Finally, it is laminated with the back paper under the relative rotation of the cooling roller 202 and the laminating roller 203, and is wound up by the winding roller 5.

[0045] Throughout the process, the self-tightening quick-release mechanism 12 ensures that the transfer roller 10 remains in contact with the adhesive roller 11, keeping the adhesive roller 11 clean. When it is necessary to remove the upper adhesive paper from the transfer roller 10, simply open the flip cover 603. When a new transfer roller 10 needs to be replaced, move the transfer roller 10 to one end and press the corresponding movable plate 1209, compressing the spring 1208. At this point, the other end of the transfer roller 10 can disengage from the hexagonal hole 1204, allowing the transfer roller 10 to be removed. Repeat the above actions to complete the replacement of the new transfer roller 10.

[0046] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
