Description

Technical Field

[0001] This utility model belongs to the field of coating machine technology, specifically a coating machine that can be adapted to different thicknesses. Background Technology

[0002] A laminating machine, also known as a plastic sealing machine, is a specialized device that uses heat and pressure to cover the surface of documents or photos with a plastic film. Its core function is to protect paper materials by laminating them, and it is commonly used in offices, schools, and homes.

[0003] In the existing technology, CN221342225U describes a gluing machine, which includes a cleaning mechanism slidably connected inside the gluing machine body. After the glue is used up, some glue remains at the bottom of the glue tank. If not cleaned regularly, the glue will clump and become fixed at the bottom of the glue tank. Therefore, a cleaning mechanism is provided. The cleaning mechanism uses a cleaning roller brush to clean the bottom of the glue tank. A third hydraulic rod controls the extension of the connecting rod and the central roller, extending the cleaning roller brush to the bottom of the tank to clean the glue tank. If the cleaning roller brush needs to be removed for cleaning or replacement, the side plate of the fixing block is opened to detach the cleaning roller brush from the central roller. This prevents residual glue from solidifying and cooling, fixing at the bottom of the glue tank, which can cause glue clumping and uneven glue application on the extrusion roller, thus avoiding unnecessary problems in the next glue use.

[0004] Existing gluing machines cannot adapt to different material thicknesses when used with materials that require gluing. Therefore, a gluing machine that can adapt to different material thicknesses is proposed to address this issue. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The present invention describes a gluing machine adaptable to different thicknesses. By setting a DC motor to drive a double-grooved screw to rotate, the slider slides and drives the rotating support rod to rotate, which in turn drives the auxiliary frame and the pressing roller to rise or fall freely, thereby changing the contact height to adapt to materials of different thicknesses for gluing.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-4 This utility model provides a gluing machine adaptable to different thicknesses, including a supporting main body base 4; a sliding rail 16 is fixedly connected to the top of the supporting main body base 4, a sliding groove 17 is formed on the inner surface of the sliding rail 16, a DC motor 18 is installed on the side of the sliding rail 16, a double-threaded screw 19 is fixedly connected to the output end of the DC motor 18, the double-threaded screw 19 is rotatably connected to the inner surface of the sliding rail 16, a slider 20 is threadedly connected to the outer surface of the double-threaded screw 19, the slider 20 is slidably connected to the inner surface of the sliding rail 16, a rotating support rod 21 is rotatably connected to the top of the slider 20, and an auxiliary frame 8 is rotatably connected to one end of the rotating support rod 21. A pressing roller 9 is rotatably connected between the frames 8. During operation, after starting the DC motor 18, the double-threaded screw 19, which has a mirrored thread along the middle part, can rotate inside the sliding track 16. At the same time, because the slider 20 is slidably connected inside the sliding track 16, and because the slider 20 is threadedly connected to the double-threaded screw 19, the rotation of the double-threaded screw 19 can drive the slider 20 to move relative to each other inside the sliding track 16. At the same time, because the slider 20 is rotatably connected to the rotating support rod 21, the rotation of the rotating support rod 21 can push the auxiliary frame 8 to move, thereby achieving the purpose of changing the height of the pressing roller 9.

[0024] Furthermore, such as Figure 2 and Figure 3As shown, the bottom of the supporting base 4 is fixedly connected to the main body 1, and the top of the main body 1 is fixedly connected to the glue tank 2. The outer wall of the main body 1 is fixedly connected to the limiting body 7, and the inner wall of the limiting body 7 is slidably connected to the limiting rod 23. The limiting rod 23 is fixedly connected to the bottom of the auxiliary frame 8. During operation, the limiting rod 23 can slide within the limiting body 7. Since the limiting rod 23 is fixedly connected to the auxiliary frame 8, the movement of the auxiliary frame 8 can be limited by the limiting rod 23. The glue tank 2 also assists in the gluing process.

[0025] Furthermore, such as Figure 3 As shown, a fixed body 3 is fixedly connected to the outer wall of the main body 1, and an air groove 22 is provided on the inner wall of the fixed body 3. During operation, the air groove 22 inside the fixed body 3 can help change the internal air pressure of the fixed body 3.

[0026] Furthermore, such as Figure 3 As shown, an adjusting screw 10 is threadedly connected to the inner surface of the fixed body 3, and a knob 11 is fixedly connected to the top of the adjusting screw 10. During operation, rotating the knob 11 allows the adjusting screw 10 to move within the internal threads of the fixed body 3.

[0027] Furthermore, such as Figure 3 As shown, a rubber piston 12 is rotatably connected to the bottom of the adjusting screw 10. The rubber piston 12 is slidably connected to the inner wall of the fixed body 3, and a rubber suction cup 13 is connected to the bottom of the fixed body 3. During operation, because the rubber piston 12 is rotatably connected to the adjusting screw 10 and slides within the fixed body 3, the adjusting screw 10 rises, causing the rubber piston 12 to rise within the fixed body 3. Simultaneously, when the rubber suction cup 13 contacts the table, the rising of the rubber piston 12 within the fixed body 3 reduces the internal air pressure of the air groove 22, thereby reducing the internal air pressure of the rubber suction cup 13. This allows the rubber suction cup 13 to adhere and fix the gluing machine.

[0028] Furthermore, such as Figure 1 As shown, a servo motor 5 is mounted on the side of the support base 4. The output end of the servo motor 5 is fixedly connected to a gluing roller 6, which is rotatably connected to the inner wall of the support base 4. During operation, after the servo motor 5 is started, it can cause the gluing roller 6 to rotate inside the support base 4, thereby achieving the function of assisting gluing.

[0029] Furthermore, such as Figure 2As shown, a transmission gear 14 is fixedly connected to one end of the glue-coating roller 6, and a transmission chain 15 is driven to the outer wall of the transmission gear 14. During operation, the rotation of the glue-coating roller 6 will synchronously drive the synchronous rotation of the transmission gear 14, thereby enabling the glue-coating roller 6 to rotate synchronously via the transmission chain 15.

[0030] Working principle: After starting the DC motor 18, the double-threaded screw 19, which has a mirrored thread along its middle section, rotates inside the sliding track 16. Simultaneously, because the slider 20 is slidably connected inside the sliding track 16 and threadedly connected to the double-threaded screw 19, the rotation of the double-threaded screw 19 drives the slider 20 to move relative to each other inside the sliding track 16. Furthermore, because the slider 20 is rotatably connected to the rotating support rod 21, the rotation of the rotating support rod 21 pushes the auxiliary frame 8 to move, thereby changing the height of the pressing roller 9. The limiting rod 23 can slide within the limiting body 7, and because it is fixedly connected to the auxiliary frame 8, the movement of the auxiliary frame 8 can be limited by the limiting rod 23. The glue tank 2 assists in applying glue, and the air groove 22 inside the fixed body 3 assists in changing the position of the fixed body. 3. The internal air pressure acts as a mechanism. After rotating knob 11, the adjusting screw 10 moves within the fixed body 3. Because the rubber piston 12 is rotatably connected to the adjusting screw 10 and slides within the fixed body 3, the adjusting screw 10 rises, causing the rubber piston 12 to rise within the fixed body 3. Simultaneously, when the rubber suction cup 13 contacts the table, the rising of the rubber piston 12 within the fixed body 3 reduces the internal air pressure of the air groove 22, thereby reducing the internal air pressure of the rubber suction cup 13. This allows the rubber suction cup 13 to adhere and fix the gluing machine. After the servo motor 5 starts, the gluing roller 6 rotates within the supporting base 4, thus assisting in the gluing process. The rotation of the gluing roller 6 synchronously drives the synchronous rotation of the transmission gear 14, allowing the gluing roller 6 to rotate synchronously via the transmission chain 15.
