[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6As shown, a gluing machine for plywood core plates comprises a gluing machine body 1; a plurality of groups of gluing shafts 11 are installed in the middle of the gluing machine body 1; a glue storage tank 12 is installed on the top of the gluing machine body 1; a glue leakage port 13 is fixedly connected to the bottom of the glue storage tank 12; the glue leakage port 13 is arranged at the top of the plurality of groups of gluing shafts 11; a bracket 14 is fixedly connected to the inner wall of the glue storage tank 12; a first rotating shaft 15 is rotatably connected to the middle of the bracket 14; two groups of top plates 16 are fixedly connected in the middle of the first rotating shaft 15; the end of the top plate 16 is arranged close to the inner wall of the glue storage tank 12; a plurality of groups of first support rods 17 are fixedly connected to the middle of the gluing machine body 1; a slide plate 18 is fixedly connected to the bottom of the plurality of groups of the first support rods 17; the slide plate 18 is located at the glue leakage port 13 is set at the bottom; the middle part of the slide plate 18 is gradually inclined; a plurality of small holes 19 are set in the middle part of the slide plate 18; when working, the staff needs to install the gluing machine body 1 and the glue storage tank 12 together, and then after the gluing machine body 1 is installed in the working area, the staff can place the processed colloid in the glue storage tank 12 for storage, and transfer the colloid to the middle part of the glue coating shaft 11 along the glue leakage port 13 at the bottom of the glue storage tank 12, and then glue the single board. By setting an inclined slide plate 18 in the middle part of the glue coating shaft 11, the colloid flowing out from the middle part of the glue leakage port 13 will contact the slide plate 18 first, and the fluidity of the colloid in the middle part of the inclined slide plate 18 makes the plurality of small holes 19 The colloid inside the slide plate 18 will be transferred to the middle part of the glue coating shaft 11 in different directions. At the same time, two groups of top plates 16 are arranged inside the glue storage tank 12, so that the two groups of top plates 16 can divide the inside of the glue storage tank 12 into a glue area and a glue-free area. When the motor on the top of the first rotating shaft 15 is used to rotate the first rotating shaft 15 and the two groups of top plates 16 inside the glue storage tank 12, the colloid inside the top plates 16 will be pushed to move, so that when the glue area is close to the glue leakage port 13, the colloid can be transferred to the middle part of the slide plate 18 by gravity. At the same time, when the top plates 16 continue to rotate, the colloid will move away from the glue leakage port 13 and stop injecting colloid into the glue leakage port 13. The staff can adjust the first rotating shaft 15 to adjust the glue area. The speed of the top motor is adjusted to adjust the amount of colloid injected into the middle of the gluing shaft 11. This step utilizes the inclined slide plate 18 in the middle of the gluing machine body 1 and the small hole 19 in the middle to reduce the amount of colloid directly transferred from the glue leakage port 13 in one direction to the middle of the gluing shaft 11. Over time, the problem of less colloid on both sides of the gluing shaft 11 is presented, and the uniformity of the glue coating of the glue coating shaft 11 by the glue leakage port 13 is improved. At the same time, the two groups of top plates 16 inside the glue storage tank 12 are used to separate the colloid inside the glue storage tank 12, and the speed of the motor at the top of the first rotating shaft 15 is used to adjust the amount of colloid output, reducing the amount of colloid directly transferred to the middle of the gluing shaft 11. Over time, the problem of colloid agglomeration and waste is presented.

[0026] like Figure 1-6As shown, the middle of the two groups of top plates 16 are fixedly connected with a fixing frame 2; the middle of the fixing frame 2 is rotatably connected with a second rotating shaft 21; the middle of the second rotating shaft 21 is fixedly connected with a screw dragon 22; the top of the second rotating shaft 21 is fixedly connected with a first tooth block 23; the middle of the first rotating shaft 15 is fixedly connected with a second tooth block 24; the first tooth block 23 and the second tooth block 24 are meshed with each other; when working, by arranging the second tooth block 24 in the middle of the first rotating shaft 15, the first rotating shaft 15 can work normally and rotate with the first tooth block 23 meshed with the second tooth block 24. A tooth block 23 can drive the second rotating shaft 21 and the auger 22 set in the middle of the fixed frame 2 to rotate, and cooperate with the multiple bending surfaces in the middle of the auger 22 to stir part of the colloid inside the glue storage tank 12. This step uses the force of the auger 22 rotating in the middle of the glue storage tank 12 to reduce the problem of part of the colloid inside the glue storage tank 12 being in a static or slightly moving state inside the glue storage tank 12, and the problem of part of the colloid inside the glue storage tank 12 solidifying and agglomerating over a long period of time, thereby improving the use cycle of the colloid inside the glue storage tank 12 and reducing the waste of colloid.

[0027] like Figure 1-6 As shown, a fixed block 3 is fixedly connected to the middle of the first rotating shaft 15; a bayonet 31 is slidably connected to the middle of the fixed block 3; a clamping block 32 is fixedly connected to the end of the bayonet 31; a slide rail 33 is provided in the middle of the fixed block 3; the clamping block 32 is slidably arranged in the middle of the slide rail 33; a guide column 34 is fixedly connected to the bottom of the bayonet 31; the guide column 34 and the glue leakage port 13 are arranged in a shape matching; during operation, by setting a fixed block 3 in the middle of the first rotating shaft 15, the staff can then rotate the clamping block 32 and align the clamping block 32 with the slide rail The rail 33 is aligned, and then the staff can loosen the latch 31 and use the downward gravity of the guide column 34 to make the block 32 slide in the middle of the slide rail 33. At the same time, the guide column 34 will slide in the middle of the glue leakage port 13 and clean up some of the attached colloid. This step, together with the sliding second tooth block 24, can improve the cleanliness of the inside of the glue leakage port 13, reduce the problem of part of the colloid adhering to the inner wall of the glue leakage port 13 after the glue leakage port 13 is used, and reduce the problem of agglomeration caused by not cleaning in time, thereby reducing the blockage of the glue leakage port 13.

[0028] like Figure 1-6 As shown, two groups of connecting rods 4 are fixedly connected to the bottom of the guide column 34; scrapers 41 are fixedly connected to the ends of the two groups of connecting rods 4; the scrapers 41 are fitted with the inside of the glue leakage port 13; during operation, the scraper 41 is arranged at the bottom of the guide column 34, so that when the guide column 34 slides down, the scraper 41 will contact the inside of the glue leakage port 13. This step cooperates with the scraper 41 to further improve the cleanliness of the inner wall of the glue leakage port 13, and reduce the problem that part of the solidified colloid is inside the glue leakage port 13, which makes it difficult to clean it only by the sliding guide column 34.

[0029] like Figure 1-6 As shown, a second support rod 5 is fixedly connected to the top of the second rotating shaft 21; a scraper 51 is fixedly connected to the end of the second support rod 5; the scraper 51 is arranged in contact with the top of the second tooth block 24; when working, by arranging the second support rod 5 at the top of the second rotating shaft 21, the second rotating shaft 21 will drive the second support rod 5 and the scraper 51 to rotate at the top of the second tooth block 24 when rotating. This step cooperates with the contact surface of the scraper 51 with the top of the second tooth block 24 to reduce the adhesion of some colloids or impurities on the top of the second tooth block 24, and improve the stability of the mutual meshing of the second tooth block 24 and the first tooth block 23.

[0030] like Figure 1-6 As shown, a sealing gasket 6 is fixedly connected to the end of the top plate 16; the sealing gasket 6 is arranged in contact with the inner wall of the glue storage tank 12; when working, a sealing gasket 6 is arranged at the end of the first rotating shaft 15, so that the sealing gasket 6 will contact the inner wall of the glue storage tank 12. This step, combined with the sealing gasket 6 made of soft material, can improve the sealing performance of the contact between the top plate 16 and the inner wall of the glue storage tank 12, and reduce the problem of part of the colloid being transferred to the other side of the top plate 16 along the gap between the top plate 16 and the glue storage tank 12.

[0031] like Figure 1-6 As shown, the side wall of the fixed block 3 is recessed. During operation, by setting the side wall of the fixed block 3 to a recessed shape, this step cooperates with the recessed surface in the middle of the fixed block 3 to improve the stability of the card block 32 placed in the middle of the fixed block 3 and reduce the problem of slipping between the card block 32 and the fixed block 3.

[0032] like Figure 1-6 As shown, a plurality of friction pads 7 are fixedly connected to the middle of the block 32; the friction pads 7 are arranged in a circular array in the middle of the block 32; during operation, by arranging a plurality of friction pads 7 in the middle of the block 32, this step cooperates with the friction pads 7 to improve the stability of the contact between the operator's hand and the block 32, and improve the friction force when the two are in contact.

[0033] Working principle: after the gluing machine body 1 and the glue storage tank 12 are installed together and the gluing machine body 1 is then installed in the working area, the staff can place the processed colloid inside the glue storage tank 12 for storage, and transfer the colloid to the middle of the gluing shaft 11 along the glue leakage port 13 at the bottom of the glue storage tank 12, and then perform gluing on the single board. By providing an inclined slide plate 18 in the middle of the gluing shaft 11, the colloid flowing out from the middle of the glue leakage port 13 will contact the slide plate 18 first, and with the fluidity of the colloid in the middle of the inclined slide plate 18, the multiple groups of small holes 19 will transfer the colloid inside the slide plate 18 to the middle of the gluing shaft 11 in different directions. At the same time, two groups of top plates 16 are arranged inside the glue storage tank 12, so that the two groups of top plates 16 can divide the inside of the glue storage tank 12 into a glue area and a glue-free area. When the motor on the top of the first rotating shaft 15 is used to rotate inside the glue storage tank 12, the colloid inside the top plates 16 will be pushed to move, so that when the glue areas are close to the glue leakage port 13, the colloid can be transferred to the middle part of the slide plate 18 by gravity. At the same time, when the top plates 16 continue to rotate, the colloid will move away from the glue leakage port 13 and stop injecting colloid into the glue leakage port 13. The staff can adjust the speed of the motor on the top of the first rotating shaft 15 to adjust the speed of the motor. The amount of colloid injected into the middle of the glue coating shaft 11 is determined by providing a second tooth block 24 in the middle of the first rotating shaft 15, so that when the first rotating shaft 15 is working normally and rotating, the first tooth block 23 engaged with the second tooth block 24 can drive the second rotating shaft 21 and the auger 22 set in the middle of the fixed frame 2 to rotate, and cooperate with the multi-section bending surface in the middle of the auger 22 to stir part of the colloid inside the glue storage tank 12. By providing a fixed block 3 in the middle of the first rotating shaft 15, the staff can then rotate the block 32 and align the block 32 with the slide rail 33, and then the staff can loosen the pin 31 and use the downward gravity of the guide column 34 to make The blocking block 32 slides in the middle of the slide rail 33, and the guide column 34 slides in the middle of the glue leakage port 13, and cleans up part of the attached colloid. A scraper 41 is provided at the bottom of the guide column 34, so that the scraper 41 contacts the inside of the glue leakage port 13 during the sliding process of the guide column 34. A second support rod 5 is provided at the top of the second rotating shaft 21, so that the second rotating shaft 21 drives the second support rod 5 and the scraper 51 to rotate at the top of the second tooth block 24 when rotating. A sealing gasket 6 is provided at the end of the first rotating shaft 15, so that the sealing gasket 6 contacts the inner wall of the glue storage tank 12, and the side wall of the fixed block 3 is set to a concave shape.
