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.
[0026] Please see Figures 1-4 This utility model provides a technical solution: a glue spraying machine for packaging box production, including a processing table 1, with two sets of support plates 2 vertically fixed at both ends of its top, a conveyor belt 3 arranged between one side of the two sets of support plates 2, and a drive mechanism for driving the conveyor belt 3 arranged between the inner wall of the conveyor belt 3 and the support plates 2.
[0027] The drive mechanism includes a transmission wheel 11 and a first motor 12. The two sets of transmission wheels 11 are rotatably connected to the two ends of one side of the two sets of support plates 2. The first motor 12 is installed at one end of one side of the support plate 2. One end of the first motor 12 passes through the support plate 2 through a rotating shaft and is connected to one end of the transmission wheel 11. The surfaces of the two sets of transmission wheels 11 are in contact with the inner wall of the conveyor belt 3.
[0028] Preferably, a cleaning component for cleaning the surface of the conveyor belt 3 is provided on one side of the conveyor belt 3 and at one end of the two sets of support plates 2.
[0029] The cleaning assembly includes: a fixed base 4, a scraper 5, and an adjustment mechanism. Two sets of fixed bases 4 are fixedly installed at one end of two sets of support plates 2.

An adjustment mechanism for adjusting the scraper 5 is provided between the two ends of the scraper 5 and the two sets of fixed bases 4.
[0030] Specifically, through the coordinated use of the fixing base 4, the scraper 5, and the adjustment mechanism, the scraper 5 is fixed between the two sets of fixing bases 4 using the adjustment mechanism, and then the blade edge of the scraper 5 is made to fit against the surface of the conveyor belt 3 using the adjustment mechanism, thereby cleaning the surface of the conveyor belt 3. This solves the problem that the device cannot clean the surface of the conveyor belt 3 and that glue drips onto the surface of the conveyor belt 3, affecting the cleanliness of the packaging box surface, thus improving the practicality of the device.
[0031] Furthermore, the adjustment mechanism includes: an adjustment groove 6, a slide rod 7, an adjustment block 8, a telescopic spring 9, and a fixing groove 10. The adjustment groove 6 is located on one side of the fixed base 4. The slide rod 7 is fixedly installed inside the adjustment groove 6. The adjustment block 8 is adapted to be connected inside the adjustment groove 6. One end of the adjustment block 8 is slidably connected to the surface of the slide rod 7. A telescopic spring 9 is provided on one side of the adjustment block 8 and on the surface of the slide rod 7.

At the same time, the cutting edge of the scraper 5 can be angled to fit against the surface of the conveyor belt 3 to ensure the preload of the telescopic spring 9.
[0032] Specifically, through the coordinated use of the adjusting groove 6, the sliding rod 7, the adjusting block 8, the telescopic spring 9, and the fixing groove 10, the adjusting block 8 slides on the sliding rod 7 in conjunction with the telescopic spring 9, allowing the scraper 5 to dynamically adjust the clamping force according to the undulations of the conveyor belt 3 surface. This solves the problems of easy jamming and rapid wear of traditional rigid scrapers 5, and improves the stability of continuous operation. At the same time, both ends of the scraper 5 are fixed in the fixing groove 10 of the adjusting block 8 with bolts, which facilitates the installation or removal of the scraper 5 and makes it easy to replace.

The output end of the electric push rod 24 passes horizontally through one side of the fixed plate 23 and extends to the other side of the fixed plate 23, where it is connected to a clamping plate 25 with a silicone protective pad. The two clamping plates 25 move synchronously in opposite directions, making the clamping force adjustable to adapt to boxes of different widths.
[0037] Working principle
[0038] Step 1: The first motor 12 drives the transmission wheel 11, which in turn drives the conveyor belt 3 to move intermittently;
[0039] When the conveyor belt 3 passes through the cleaning component, the unevenness or residual adhesive particles on the surface of the conveyor belt 3 can be removed by the scraper 5. At the same time, the scraper 5 is pushed by the reverse force to the adjusting block 8 along the slide rod 7 to compress the telescopic spring 9, which can realize dynamic displacement compensation and avoid jamming. Then the spring restoring force makes the scraper 5 continue to stick to the conveyor belt 3, and can continuously scrape off the residual adhesive on its surface.
[0040] Step 2: After placing the packaging box on the surface of the conveyor belt 3, the electric push rod 24 pushes the clamping plate 25 to clamp the box body, and the protective pad prevents the surface of the box body from being crushed.
[0041] Cylinder 15 pushes the sliding seat 16 down, so that the glue spray head 21 is in an appropriate position relative to the box surface;
[0042] The second motor 19 drives the bidirectional lead screw 18 to synchronously adjust the distance between the two glue spraying heads 21 to match different box widths;
[0043] The glue tank 14 outputs glue liquid through the glue supply pipe 22 to the glue spray head 21, and uses pressure to realize the glue spraying process on the packaging box.
[0044] Step 3: After the adhesive is applied, the clamping plate 25 is released, and the conveyor belt 3 transfers the finished product; the scraper 5 continues to clean the belt surface, preparing for the next cycle.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
