[0035] This utility model embodiment provides a cleaning device for the blade of an adhesive applicator. Figure 1 This is a schematic diagram of a glue applicator blade cleaning device provided in an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating the working process of a glue applicator blade cleaning device according to an embodiment of the present invention. Figure 3 This is a schematic diagram showing the positions of the scraper and the glue applicator cutter head according to an embodiment of this utility model. (Reference) Figures 1-3 The glue applicator blade cleaning device includes:

[0036] Conveying mechanism 10, scraper fixing bracket 20, and scraper 30;

[0037] The scraper 30 is mounted on the scraper fixing bracket 20;

[0038] The conveying mechanism 10 includes a conveyor belt 11 and a guide rail 12. The scraper fixing bracket 20 is fixed on the guide rail 12 and is fixedly connected to the conveyor belt 11.

[0039] The conveyor belt 11 is used to drive the scraper fixing bracket 20 to move along the guide rail 12, so that the scraper 30 cleans the glue outlet slit of the glue applicator head.

[0040] in, Figure 2 A front view of the glue applicator blade 50 and scraper 30 is shown. Figure 3 A side view of the glue applicator head 50 and scraper 30 is shown.

[0041] Specifically, when poor glue application is detected or the specified cleaning time is reached, the glue applicator head 50 moves directly above the head cleaning device and slowly descends until the scraper blade 30 enters the glue outlet slit 51 of the glue applicator head 50. The conveyor belt 11 starts operating, and since the scraper blade fixing bracket 20 is fixedly connected to the conveyor belt 11, it also moves accordingly. As the conveyor belt 11 drives the scraper blade fixing bracket 20, it moves along the guide rail 12. The guide rail 12 ensures that the scraper blade fixing bracket 20 and the scraper blade 30 can move stably and accurately along the glue outlet slit 51 of the glue applicator head. With the continuous movement of the conveyor belt 11, the scraper blade 30 slides within the glue outlet slit 51, thereby removing excess glue or impurities adhering to the slit. When the glue outlet slit 51 is cleaned, the glue applicator head 50 leaves the scraper blade 30. When the glue applicator head 50 rises to the pre-applied glue position, the operator can observe from outside the glue applicator head 50 whether the glue is being dispensed smoothly. If it is, the machine can be restarted for product production; if it is not, it needs to be cleaned again.

[0042] Furthermore, the scraper 30 is detachably fixed to the scraper fixing bracket 20, and a scraper 30 of the corresponding size can be replaced according to the size of the glue dispensing slit 51 of the cutter head. The conveyor belt 11 can move back and forth at a certain speed, driving the scraper 30 to clean the glue dispensing slit of the cutter head multiple times, ensuring that the residue in the slit is removed in a timely and effective manner, reducing slit blockage.

[0043] The glue applicator head cleaning device provided in this embodiment includes a conveying mechanism 10, a scraper fixing bracket 20, and a scraper 30. The scraper 30 is mounted on the scraper fixing bracket 20. The conveying mechanism 10 includes a conveyor belt 11 and a guide rail 12. The scraper fixing bracket 20 is fixed on the guide rail 12 and is fixedly connected to the conveyor belt 11. The conveyor belt 11 drives the scraper fixing bracket 20 to move along the guide rail 12, so that the scraper 30 cleans the glue outlet slit 51 of the glue applicator head. Driven by the conveyor belt 11, the scraper fixing bracket 20 can move along the guide rail 12, driving the scraper 30 to automatically clean the glue outlet slit 51 of the glue applicator head, realizing automatic cleaning of the glue applicator, reducing slit blockage and the frequency of personnel entering and exiting the glue applicator, shortening downtime, preventing dust generation from personnel entering the glue applicator, and improving equipment uptime and product yield.

[0044] Based on the above embodiments, optionally, the conveying mechanism 10 may also include a motor 13 and a driven wheel 14;

[0045] Motor 13 and driven wheel 14 are located at both ends of conveyor belt 11. Motor 13 is used to drive conveyor belt 11 to move around motor 13 and driven wheel 14.

[0046] Specifically, when poor glue application is detected or the specified cleaning time is reached, the glue applicator head 50 moves directly above the head cleaning device. The glue applicator head 50 slowly descends until the scraper 30 enters the head slit. The head cleaning device motor starts, and the motor 13 drives the conveyor belt 11 to move around the motor 13 and the driven wheel 14. The conveyor belt 11 drives the scraper fixing bracket 20 to move along the guide rail 12, causing the scraper 30 to automatically scrape and clean the glue outlet slit 51 of the glue applicator head 50. After reaching the set number of scraping operations, the cleaning action is completed, and the glue applicator head 50 rises to the pre-applied glue position, achieving automatic cleaning.

[0047] Figure 4 This is a schematic diagram of another adhesive applicator blade cleaning device provided in this embodiment of the present invention. Optional, see reference. Figure 4 The glue applicator blade cleaning device also includes:

[0048] Main load-bearing support 40;

[0049] The guide rail 12, motor 13 and driven wheel 14 are fixed on the main load-bearing bracket 40.

[0050] Specifically, the main load-bearing bracket 40 serves as the foundational support structure for the entire cleaning device, ensuring the stable installation of key components such as the guide rail 12, motor 13, and driven wheel 14. This prevents malfunctions caused by loosening or displacement of components, thereby improving the overall stability and reliability of the cleaning device. The main load-bearing bracket 40 can adjust the height of the scraper 30 according to the height of the glue outlet slit 51 of the glue applicator, allowing the scraper 30 to better enter the glue outlet slit 51 and clean it more effectively.

[0051] Optionally, the glue applicator blade cleaning device includes at least two different thicknesses of scraper blades 30;

[0052] Scrapers 30 of different thicknesses are used to clean the glue outlet slits 51 of different sized blades.

[0053] Specifically, scraper blades 30 of varying thicknesses can clean the adhesive dispensing slits 51 of different sized blades, improving the versatility and flexibility of the cleaning device. Scraper blades 30 of different thicknesses can precisely clean slits of varying widths. Thinner blades 30 are suitable for narrow gaps, capable of reaching hard-to-reach areas; while thicker blades 30 are suitable for wider gaps, providing stronger cleaning power. This design ensures thorough and effective cleaning, reducing slit clogging.

[0054] Figure 5 This is a schematic diagram of a scraper fixing bracket provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of another scraper fixing bracket provided in an embodiment of this utility model. Optionally, refer to... Figures 4-6 The scraper fixing bracket 20 includes a sliding part 21 and a scraper fixing part 22;

[0055] The sliding part 21 is connected to the guide rail, and the scraper fixing part 22 is connected to the sliding part 21;

[0056] The scraper 30 is detachably fixed to the scraper fixing part 22; or, the scraper fixing part 22 includes a plurality of scraper fixing positions 221, each scraper fixing position 221 is used to fix a scraper 30, at least some of the scraper fixing positions 221 fix scrapers 30 with different thicknesses, and the positions of the plurality of scraper fixing positions 221 of the scraper fixing part 22 are movable to switch the scraper 30 used for cleaning the glue outlet slit of the blade head.

[0057] Specifically, when the scraper blade 30 wears out due to prolonged use or needs to be replaced, the scraper blade 30 can be removed and replaced with a new one. Alternatively, the scraper blade fixing position 221 can be moved to switch the scraper blade 30, improving switching efficiency.

[0058] refer to Figure 5 The sliding part 21 is slidably connected to the guide rail, and can slide along the guide rail. The scraper fixing part 22 is fixedly connected to the sliding part 21, and the scraper 30 is detachably fixed to the scraper fixing part 22. Different thickness scrapers 30 can be replaced according to different glue applicator heads. By setting the scraper 30 to be detachably fixed to the scraper fixing part 22, scrapers 30 of different thicknesses can be quickly and easily replaced to adapt to the glue dispensing slits of different sizes of glue applicator heads, shortening downtime and improving production efficiency.

[0059] In addition, refer to Figure 6 By configuring the scraper fixing part 22, which includes multiple scraper fixing positions 221, the positions of these multiple scraper fixing positions 221 are movable. At least some of the scraper fixing positions 221 fix scrapers 30 with different thicknesses. When cleaning the glue outlet slits of the blade head with different slit widths, the scraper fixing positions 221 can be moved to switch the scraper 30 and select a scraper 30 that corresponds to the size of the glue outlet slit. This ensures that the scraper 30 can maintain good contact with the glue outlet slit, thereby improving the cleaning effect and efficiency. For example, a thicker scraper 30 can be used for a blade head glue outlet slit with a larger slit width, and a thinner scraper 30 can be used for a blade head glue outlet slit with a smaller slit width. This ensures that the scraper 30 can enter the blade head glue outlet slit and that the distance between the scraper 30 and the side wall of the blade head glue outlet slit is small, so that the glue on the side wall of the blade head glue outlet slit can be fully scraped off.

[0060] Optional, see reference Figure 6 The scraper fixing part 22 also includes a rotating shaft 222 fixedly connected to the sliding part 32, and a plurality of scraper fixing positions 221 are disposed on the rotating shaft 222.

[0061] Specifically, the scraper fixing position 221 can rotate around the rotating shaft 222 to switch the scraper fixing position 221.

[0062] Optionally, the thickness of the scraper 30 is less than or equal to 550 micrometers. For example, the thickness of the scraper 30 is 10 micrometers, 20 micrometers, 30 micrometers, 40 micrometers, 100 micrometers, 200 micrometers, 300 micrometers, 400 micrometers, or 500 micrometers.

[0063] Preferably, the thickness of the scraper 30 is less than or equal to 55 micrometers.

[0064] Specifically, the width of the glue outlet slit of the blade is generally 55-60 micrometers. By setting the thickness of the scraper 30 to be less than or equal to 55 micrometers, it can be ensured that the scraper 30 can completely enter the slit, effectively scrape off the residual glue, and avoid the clogging problem caused by glue residue.

[0065] Optional, see reference Figure 2 The length of the guide rail 12 and the maximum conveying distance of the conveyor belt 11 are both greater than the length of the glue outlet slit 51 of the cutter head.

[0066] Specifically, since the length of the guide rail 12 and the maximum conveying distance of the conveyor belt 11 are both greater than the length of the glue outlet slit 51 of the blade, the scraper 30 can clean the entire glue outlet slit 51 of the blade once when it moves from one end of the guide rail to the other end under the drive of the conveyor belt 11. The cleaning of the entire glue outlet slit 51 of the blade can be completed without adjusting the position of the glue outlet slit 51 of the blade and the position of the cleaning device, thus improving the cleaning efficiency.

[0067] Optionally, the conveyor belt 11 is used to drive the scraper fixing bracket 20 to reciprocate along the guide rail 12, so that the scraper 30 cleans the glue outlet slit 51 of the glue applicator.

[0068] Specifically, driven by the conveyor belt 11, the scraper fixing bracket 20 and the scraper 30 can automatically reciprocate at the glue outlet slit of the glue applicator head, thereby achieving multiple cleanings of the glue outlet slit 51 of the head and improving cleaning efficiency.

[0069] According to another aspect of the present invention, a glue application system is provided, including a glue applicator and a glue applicator blade cleaning device as described in any embodiment of the present invention.
