Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to an automatic adhesive application device. Background Technology

[0002] An automatic gluing device is a piece of equipment used to automatically apply glue or other adhesives during the production process. It can automatically apply glue to the surface of white cardboard materials that need to be laminated with aluminized film or aluminum foil, ensuring that the glue is evenly distributed so that the subsequent lamination process of aluminized film or aluminum foil can proceed smoothly with the paper. Its main function is to apply a thin layer of glue to the white cardboard before lamination, helping the aluminized film or aluminum foil to form a strong adhesion to the surface of paper, leather, cloth, etc.

[0003] Existing automatic gluing devices typically use a gluing roller to evenly apply glue from a glue tank to the surface of white cardboard. While this process is efficient, in practice, operators need to constantly monitor the glue level in the glue tank. Insufficient glue can lead to uneven or incomplete coating, affecting the quality of the lamination. Furthermore, if the glue level is too low, the gluing roller may malfunction, causing production to stop or coating to be interrupted. To avoid this, operators need to frequently check and replenish the glue, which not only increases the workload in the production process but also consumes extra time and effort. Utility Model Content

This significantly reduces manual intervention and avoids the tedious process of frequent manual checks and adhesive replenishment. It solves the problem in existing technologies where operators need to constantly monitor the adhesive level in the glue tank to prevent insufficient adhesive from causing uneven coating or inadequate application, thus affecting the quality of the lamination effect.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0036] Example 1, please refer to Figure 1-5 This utility model provides a technical solution: an automatic gluing device, including a base 1, a glue tank 101 fixedly installed on the top of the base 1, a movable plate 102 movably embedded inside the glue tank 101, and return springs 103 fixedly installed on both sides of the bottom of the movable plate 102. The other ends of the two return springs 103 are fixedly installed on the bottom side of the inner wall of the glue tank 101. A support plate 106 is fixedly installed on the left side of the glue tank 101. The device also includes: a first strong magnet 104 fixedly installed on the bottom left side of the movable plate 102, with two first ball bearings 105 disposed on the left side of the first strong magnet 104, both of which are movably connected to the left side of the inner wall of the glue tank 101; and two sliding rods 107 fixedly installed on the bottom of the support plate 106. All are fixedly installed on the top of the base 1. The outer surfaces of the two slide rods 107 are slidably connected to the sliders 108. The right side of the sliders 108 is fixedly installed with a second strong magnet 109. The right side of the second strong magnet 109 is provided with two second balls 110. The two balls 110 are movably connected to the left outer surface of the glue tank 101. The top of the sliders 108 is provided with a contact element 111. The bottom of the support plate 106 is provided with a touch switch 112. The rear side of the glue tank 101 is fixedly installed with a first feed pipe 113. The other end of the first feed pipe 113 is fixedly installed with a pump 114. The touch switch 112 is electrically connected to the pump 114. The front side of the pump 114 is fixedly installed on the rear side of the glue tank 101. The rear side of the pump 114 is fixedly installed with a second feed pipe 115.

[0037] In this embodiment, the operator can first insert one end of the second feed pipe 115 into the glue storage tank. When the glue is evenly applied from the glue tank 101 on the base 1 to the surface of the white cardboard using the glue coating roller 201, the glue level inside the glue tank 101 gradually decreases. When the glue level decreases, the reset spring 103 gradually resets, pushing the movable plate 102 upwards. As the movable plate 102 rises, it pulls the first strong magnet 104 upwards synchronously. The first strong magnet 104 drives the first ball bearing 105 to roll against the inner wall of the glue tank 101. When the first strong magnet 104 rises, it drives the second strong magnet 109 to move due to the principle of opposite poles attracting each other. The second strong magnet 109 then drives the second ball bearing 110 to roll in the glue tank 101. The outer surface of 01 rolls while pulling the slider 108 to slide upward on the outer surface of the slide bar 107. After the slider 108 slides to a certain extent, it will drive the contact member 111 to contact the touch switch 112, thereby activating the drive system of the pump 114 to draw out the glue inside the storage tank through the second feed pipe 115 and inject it into the glue tank 101 through the first feed pipe 113. The structure of the movable plate 102 and the second strong magnet 109 can replenish the glue in the glue tank 101. When the glue gradually decreases during the coating process, the reset spring 103 pushes the movable plate 102 to rise, thereby activating the pump 114 to automatically draw out the glue in the storage tank and inject it into the glue tank 101, which greatly reduces manual intervention and avoids the tedious process of frequent manual inspection and glue addition.

[0038] Example 2, as Figure 1-5 As shown, rotating rods 2 are movably embedded on both sides of the inside of the glue tank 101. A motor 202 is fixedly installed on the left side of one of the rotating rods 2. The bottom of the motor 202 is fixedly installed on the top of the support plate 106. Glue rollers 201 are provided on the outer surfaces of both rotating rods 2. Gears 203 are fixedly installed on the right side of both rotating rods 2. The two gears 203 mesh with each other. A gantry frame 204 is fixedly installed on the top of the base 1. Electric telescopic rods 205 are provided on both sides of the top of the gantry frame 204. Connectors 206 are provided at the bottom of both electric telescopic rods 205. Positioning rollers 207 are provided on the opposite side of the two connectors 206.

[0039] In this embodiment, the operator first places the white cardboard on top of the coating roller 201 and at the bottom of the positioning roller 207. Then, the electric telescopic rod 205 on the gantry 204 is activated via its power supply system, allowing it to extend and lower the positioning roller 207 via the connector 206. This allows the positioning roller 207 to adhere to the surface of the white cardboard. Next, the motor 202 on the support plate 106 is activated via its power supply system, enabling it to drive the bottom rotating rod 2 through its output shaft. The bottom rotating rod 2 then drives the top rotating rod 2 via the gear 203, causing the two coating rollers 201 to rotate. 1. It can rotate in opposite directions. When the bottom coating roller 201 rotates, it can transfer the glue inside the glue tank 101 to the top coating roller 201. Then, the white cardboard can be coated with glue through the top coating roller 201. Through the structure of the rotating rod 2 and the positioning roller 207, not only can the two coating rollers 201 rotate in opposite directions to transfer the glue evenly from the glue tank 101 to the surface of the white cardboard, ensuring the thickness and uniformity of the glue coating and avoiding the problem of uneven or excessive glue coating, but the positioning roller 207 can accurately position the white cardboard between the coating rollers 201, avoiding possible deviation during the glue coating process and ensuring the uniformity and high quality of the glue coating.

[0040] Working principle: In use, the operator first inserts one end of the second feed pipe 115 into the glue storage tank. As the glue coating roller 201 evenly applies the glue from the glue tank 101 on the base 1 to the surface of the white cardboard, the glue level inside the glue tank 101 gradually decreases. When the glue level decreases, the return spring 103 gradually returns to its original position, pushing the movable plate 102 upwards. The movable plate 102 has a counterweight on its bottom right side. As the movable plate 102 rises, it pulls the first strong magnet 104 upwards synchronously. The first strong magnet 104 drives the first ball bearing 105 to roll against the inner wall of the glue tank 101. When the first strong magnet 104 rises, it drives the second strong magnet 109 to move due to the principle of opposite poles attracting each other. The second ball bearing 110 rolls on the outer surface of the glue tank 101, while simultaneously pulling the slider 108 to slide upwards on the outer surface of the slide bar 107. After the slider 108 slides to a certain extent, it will cause the contact element 111 to contact the touch switch 112, thereby activating the drive system of the pump 114. This allows the glue inside the storage tank to be drawn out through the second feed pipe 115 and injected into the glue tank 101 through the first feed pipe 113. Furthermore, the structure of the movable plate 102 and the second strong magnet 109 can replenish the glue in the glue tank 101. When the glue gradually decreases during the coating process, the return spring 103 pushes the movable plate 102 upwards, thereby activating the pump 114 to automatically draw out the glue from the storage tank and inject it into the glue tank 101. This greatly reduces manual intervention and avoids the tedious process of frequent manual checks and glue additions.In use, the operator first places the white cardboard on top of the coating roller 201 and at the bottom of the positioning roller 207. Then, the electric telescopic rod 205 on the gantry 204 is activated, extending to lower the positioning roller 207 via the connector 206, allowing it to adhere to the surface of the cardboard. Next, the motor 202 on the support plate 106 is activated, driving the bottom rotating rod 2 via its output shaft. The bottom rotating rod 2 then drives the top rotating rod 2 via gear 203, causing the two coating rollers 201 to rotate in opposite directions. When the bottom coating roller 201 rotates, it transfers the glue inside the glue tank 101 to the top coating roller 201. The top coating roller 201 then coats the white cardboard with glue. The structure of the rotating rod 2 and the positioning roller 207 not only allows the two coating rollers 201 to rotate in opposite directions, ensuring that the glue is evenly transferred from the glue tank 101 to the surface of the white cardboard, thus ensuring the thickness and uniformity of the glue coating and avoiding uneven or excessive glue coating, but also allows the positioning roller 207 to accurately position the white cardboard between the coating rollers 201, preventing any possible deviation during the glue coating process. This ensures the uniformity and high quality of the glue coating, thus preventing any issues that could affect the quality of the lamination effect.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
