Description

Technical Field

[0001] This utility model belongs to the field of glue coating equipment, and in particular relates to a glue tank. Background Technology

[0002] In the packaging industry, the barrier properties of packaging materials are a key factor in ensuring product quality, extending shelf life, and preventing adverse effects from external factors such as oxygen, moisture, and light. This is especially true in industries such as food, pharmaceuticals, and electronics, where the barrier properties of packaging materials directly impact product safety and sustainability. Therefore, improving the barrier properties of packaging materials has become an important development direction for the packaging industry.

[0003] As a crucial tool for coating packaging materials, adhesive coating equipment plays a vital role in improving the barrier properties of these materials. Traditional adhesive coating techniques typically use dispensing machines, coating machines, and other equipment to evenly coat the surface of packaging materials, forming a protective film with specific functions. This film effectively enhances the barrier properties of packaging materials, such as moisture resistance, oxygen protection, and UV resistance. However, existing technologies and traditional adhesive coating equipment have certain limitations. Uneven adhesive distribution is a common problem, affecting coating quality and uniformity. This not only impacts the performance of the packaging materials but can also lead to material waste and reduced production efficiency. Furthermore, traditional equipment often fails to fully consider the surface characteristics and requirements of different packaging materials during the coating process, resulting in suboptimal coating effects and difficulty in consistently achieving improved barrier properties.

[0004] Chinese patent document CN208878977U discloses a glue tank, including a glue tank body with a glue inlet at the top. The glue tank also includes a defoaming channel disposed above the glue tank body. The glue tank further includes a defoaming body, at least a portion of which is formed by the defoaming body. The defoaming body is detachably disposed inside the glue tank body and located below the glue inlet. The defoaming channel has an upper wall and an opposing lower wall, the upper wall being formed by the defoaming body. A plurality of defoaming needles are disposed inside the defoaming channel. The bottom of each defoaming needle is fixed to the lower wall, and its top faces the upper wall.

[0005] In the above technical solution, although defoaming channels with defoaming needles are set below the glue inlet to eliminate air bubbles in the glue and prevent them from entering the laminate, achieving efficient removal of air bubbles in the glue, in actual use, the required coating liquid level varies depending on factors such as glue viscosity and flow rate. The existing glue tank structure lacks a mechanism to adjust the liquid level, resulting in the glue tank level not changing accordingly when using glues of different viscosities, leading to low coating efficiency.

[0006] Therefore, it is necessary to develop a new type of glue tank that can adjust and maintain the liquid level height accordingly when dealing with different glues and materials, so as to improve the efficiency of glue application. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a new type of glue tank that can adjust and maintain the liquid level height according to different coating requirements when dealing with different glues and materials, thereby improving the efficiency of glue coating.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a glue tank, including a base, a glue tank body disposed on the base, glue inlet baffles installed on both sides of the glue tank body, the area between the glue tank body and the glue inlet baffles forming a glue container, a glue roller placed above the glue container, a movable baffle assembly disposed on the glue tank body for adjusting the liquid level height of the solution in the glue tank body; and an overflow groove disposed on the glue tank body.

[0009] The glue tank body is a crucial component for holding the glue. Connected to the base, it ensures smooth glue delivery during the application process. Glue inlet baffles are installed on both sides of the glue tank body, primarily to confine the glue entering the tank to a specific area. The glue container design guarantees uniform glue distribution. The glue roller is positioned above the glue container to evenly apply the glue to the surfaces of the materials to be bonded. The movable baffle assembly regulates the liquid level within the glue tank body. By adjusting the position of the movable baffle assembly, the glue level in the container can be changed, thereby controlling the amount of glue used and the coating effect. This allows the equipment to adjust and maintain the liquid level according to different coating requirements when dealing with different glues and materials, improving coating efficiency.

[0010] Preferably, a position adjustment mechanism is connected below the movable baffle assembly, the position adjustment mechanism being used to control the height of the movable baffle assembly; the movable baffle assembly includes a transmission component, a shock-absorbing flat pad, and a sliding push plate, the transmission component being connected to the position adjustment mechanism through the shock-absorbing flat pad, the sliding push plate being fixed on the transmission component, the sliding push plate being attached to the glue groove body, and sliding up and down along the glue groove body.

[0011] The transmission component plays a role in linking and transmitting motion. Through its connection with other components, the transmission component enables the movable baffle to move up and down, thereby controlling the liquid level of the solution. The shock-absorbing pad, as the connecting component between the transmission component and the position adjustment mechanism, is made of highly elastic material. Its main function is to reduce shock and buffer. During the movement of the transmission component, the shock-absorbing pad effectively absorbs and reduces the vibration and impact generated during the transmission process, maintaining the smoothness of the transmission process and improving the quality of glue application. The sliding push plate is fixed on the position adjustment mechanism and is used to control the liquid level in the glue tank. The sliding push plate slides up and down along the glue tank body to ensure accurate adjustment of the glue level, thereby achieving precise control of the liquid level in the glue tank.

[0012] Preferably, the edge of the sliding push plate is serrated.

[0013] The serrated edge design of the sliding push plate not only ensures uniform glue overflow, but also breaks up air bubbles during the overflow process, preventing them from accumulating on the glue surface. This reduces the negative impact of air bubbles on glue coating quality and improves coating efficiency and quality.

[0014] Preferably, the position adjustment mechanism includes a cylinder and a piston rod. Two cylinders are symmetrically fixed on the base, and each cylinder contains a piston rod. The top end of the piston rod is connected to the movable baffle assembly.

[0015] The cylinders are symmetrically mounted on the base, ensuring even distribution of force during system operation. This symmetrical structural design enhances the overall system stability and prevents equipment tilting or damage caused by uneven force on one side. The top of the piston rod is connected to the movable baffle assembly. Driven by the cylinder, the movable baffle can be precisely adjusted to the required position. The pushing and pulling forces provided by the cylinder can precisely control the movement range and speed of the movable baffle, ensuring the accuracy of liquid level control and improving the efficiency of adhesive application.

[0016] Preferably, the glue inlet baffle has glue outlets on the upper parts of both sides, and the glue overflow troughs are fixedly connected to the upper outer walls of both sides of the glue inlet baffle. The glue outlets guide the material in the glue trough body to the glue overflow trough.

[0017] The glue outlet guides the material in the glue tank to the overflow tank, effectively managing and controlling the flow direction and flow rate of the glue, ensuring that excess glue can be discharged smoothly without affecting the glue application operation; by precisely controlling the glue flow, the uniformity and quality of the glue application are improved, making the glue application effect more stable and reliable.

[0018] Preferably, a glue drain pipe is provided at the bottom of the glue overflow tank, and a glue drain ball valve is installed on the glue drain pipe.

[0019] The main function of the glue drain pipe is to provide a specific glue outlet channel for the glue overflow tank, so as to drain the excess glue collected in the overflow tank, making the glue draining process smoother, reducing the possibility of glue retention or accumulation in the overflow tank, and ensuring the timeliness and effectiveness of glue draining; the glue drain ball valve plays a regulating and controlling role in the glue draining system. By accurately adjusting and controlling the opening degree of the valve, the glue discharge speed and flow rate can be precisely controlled, thereby meeting different usage requirements.

[0020] Preferably, the glue tank body further includes a glue inlet surface, a glue inlet is provided on the glue inlet surface, and a blade assembly is provided above the glue inlet; glue inlet pipes are installed on the glue inlet at equal intervals, and each glue inlet pipe is provided with a one-way valve.

[0021] The glue inlet surface is part of the glue tank body and is used to receive and guide glue into the glue tank. The glue inlet is located on the glue inlet surface and is the main channel for glue to enter the glue tank, allowing the glue to flow into the glue tank quickly and efficiently. Glue inlet tubes are installed on the glue inlets and are evenly distributed. This design significantly improves the uniformity of glue distribution and significantly reduces the problems of blockage and inconsistent flow rates that may be caused by a single channel. The evenly distributed glue inlet tubes ensure that each tube at the glue inlet performs equally well, allowing the glue to be properly pre-distributed before entering the glue tank. One-way valves ensure that the glue flows in only one direction, preventing backflow and blockage. Each one-way valve is highly sensitive and has a fast response, opening or closing instantly when the glue pressure changes, ensuring that the glue flows smoothly and unidirectionally into the glue tank, improving the uniformity and quality of glue application.

[0022] Preferably, the blade assembly includes a blade mounting base and a blade edge. The blade mounting base is fixed on the glue tank body, and the blade edge is disposed on the blade mounting base. The blade edge rests against the outer edge of the glue roller during use.

[0023] The blade mount is a base bracket used to fix the blade, providing a stable support platform to ensure that the blade assembly remains firm during operation; the blade is used to clean residues on the glue roller and prevent glue from accumulating on the roller surface, which enables the glue roller to perform continuous and efficient glue application operations, ensuring the uniformity and stability of the glue application.

[0024] Preferably, the movable baffle assembly is provided with a guide rail, two bearing seats are symmetrically distributed at both ends of the guide rail, a transverse lead screw is provided between the two bearing seats, a slider is slidably connected to the transverse lead screw, and a stirring component is connected to the slider.

[0025] The guide rail provides the track for the slider to move. Combined with the design of two bearing seats and a transverse lead screw, it ensures that the slider can move smoothly and accurately on the guide rail. The main function of the mixing component is to stir and homogenize the glue, so that the glue remains in a uniform state in the glue tank, preventing glue sedimentation and separation, and ensuring the quality and uniformity of glue distribution during the application process.

[0026] Preferably, the mixing assembly includes a gearbox, a heating rod, and rotating blades. The gearbox is connected to the slider, the heating rod is disposed inside the gearbox, and the rotating blades are connected to the outer edge of the heating rod.

[0027] As the core transmission component of the mixing assembly, the gearbox efficiently transmits energy from the power source through the precise meshing of internal gears, driving the heating rod and rotating blades. The heating rod, built into the gearbox, provides continuous and uniform heating through an electric heating element, ensuring that the adhesive maintains a suitable temperature throughout the operation. A suitable temperature guarantees the viscosity and flowability of the adhesive, making the application smoother and more uniform, effectively preventing quality instability caused by temperature changes. The rotating blades, connected to the heating rod, rotate under the drive of the gearbox, thoroughly mixing the adhesive and maintaining a uniform mixing state. This ensures effective generation of mixing force and uniform flow of the adhesive, preventing sedimentation and stratification, and improving the quality and effect of the coating.

Detailed Implementation

[0037] As attached Figures 1-7 As shown, a glue tank in this embodiment includes a base 1, a glue tank body 2 disposed on the base 1, glue inlet baffles 3 installed on both sides of the glue tank body 2, the area between the glue tank body 2 and the glue inlet baffles 3 forming a glue container 4, a glue roller 5 placed above the glue container 4, and a movable baffle assembly 3 disposed on the glue tank body 2 for adjusting the liquid level height in the glue tank body 2; the glue tank body 2 is also provided with an overflow groove 6.

[0038] Specifically, such as Figure 1 , Figure 4 As shown, a position adjustment mechanism is connected below the movable baffle assembly, which controls the height of the movable baffle assembly. The movable baffle assembly includes a transmission component 7, a shock-absorbing flat pad 8, and a sliding push plate 9. The transmission component 7 is connected to the position adjustment mechanism through the shock-absorbing flat pad 8. The sliding push plate 9 is fixed to the transmission component 7 and adheres to the glue tank body 2, sliding up and down along the glue tank body 2. Glue outlets 10 are provided on the upper parts of both sides of the glue inlet baffle 3, and overflow grooves 6 are fixedly connected to the upper outer walls of both sides of the glue inlet baffle 3. The glue outlets 10 guide the material in the glue tank body 2 into the overflow grooves 6. It should be noted that, as Figure 4 As shown, the edge of the sliding push plate 9 is set in a serrated shape.

[0039] like Figure 2 , Figure 4 As shown, a glue discharge pipe 11 is provided at the bottom of the glue overflow tank 6, and a glue discharge ball valve 12 is installed on the glue discharge pipe 11. The position adjustment mechanism includes a cylinder 13 and a piston rod 14. Two cylinders 13 are symmetrically fixed on the top outer wall of the base 1. A piston rod 14 is provided in each of the two cylinders 13. The top end of the piston rod 14 is connected to the movable baffle assembly.

[0040] Specifically, such as Figures 5-7As shown, the glue tank body 2 also includes a glue inlet surface, a glue inlet 15 is provided on the glue inlet surface, a blade assembly is provided above the glue inlet 15, glue inlet tubes 16 are installed on the glue inlet 15 at equal intervals, and each glue inlet tube 16 is provided with a one-way valve.

[0041] like Figure 3 As shown, the blade assembly includes a blade mounting base 17 and a blade 18. The blade mounting base 17 is fixed on the glue tank body 2, and the blade 18 is disposed on the blade mounting base 17. When in use, the blade 18 rests against the outer edge of the glue roller 5.

[0042] like Figure 2 , Figure 5 As shown, the movable baffle assembly is provided with a detachable guide rail 19. Two bearing seats 20 are symmetrically distributed at both ends of the guide rail 19. A transverse lead screw 21 is provided between the two bearing seats 20. A slider 22 is slidably connected to the transverse lead screw 21. The slider 22 is connected to a stirring assembly. The stirring assembly includes a gearbox 23, a heating rod 24 and a rotating blade 25. The gearbox 23 is connected to the slider 22. The heating rod 24 is provided inside the gearbox 23. The rotating blade 25 is connected to the outer edge of the heating rod 24.

[0043] In actual use, the glue is introduced into the glue tank 4 inside the glue tank body 2 through the glue inlet 15. The glue in the glue tank 4 is evenly injected into the glue tank 4 by multiple glue inlet pipes 16 that are evenly distributed and through a one-way valve (to prevent glue backflow), ensuring that the glue is evenly distributed in the glue tank without air bubbles or uneven areas.

[0044] At this point, the operator adjusts the liquid level in the glue tank according to the viscosity and flow rate requirements of the glue, using the movable baffle assembly 3. The cylinder 13 drives the piston rod 14 to adjust the up-and-down position of the sliding push plate 9, which fits against the glue tank body 2. The edge of the sliding push plate 9 is serrated to facilitate uniform glue overflow. After the glue is regulated within the glue tank body 2, the glue roller 5 begins to rotate. The blade 18 rests against the outer edge of the glue roller 5, scraping away uneven areas to prevent glue accumulation on its surface. The glue roller 5 evenly coats the surface of the object to be treated, ensuring a consistent coating thickness. As the liquid level is continuously adjusted, excess glue flows into the overflow tank 6 through the glue outlet 10.

[0045] It should be noted that, in order to ensure the uniformity of the adhesive, the adhesive container 4 is also equipped with a detachable stirring component. The gearbox 23 transmits power to the heating rod 24 and the rotating blades 25. The heating rod 24 heats the adhesive in the adhesive container 4 to keep it at a suitable working temperature, ensuring that the viscosity and flowability of the adhesive meet the application requirements. The rotating blades 25 stir the adhesive as the heating rod 24 rotates, keeping the adhesive in a uniform mixing state, preventing the adhesive from settling and separating, and ensuring the uniformity of the adhesive during the application process.

[0046] After coating is completed, the mixing assembly needs to be disassembled. Then, by adjusting the position of the sliding push plate 9, any overflowing glue will automatically flow into the overflow tank 6. The overflow tank 6 is connected to the external waste recycling system through the bottom discharge pipe 11. Waste glue is effectively collected, avoiding waste and reducing pollution.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
