Description

Technical Field

[0001] This utility model relates to the field of adhesive dilution technology, specifically a dilution device. Background Technology

[0002] Water-based pressure-sensitive adhesives are widely used in various bonding, encapsulation, and protective materials. Especially in the production of weather-resistant, high-adhesion paper-based pressure-sensitive adhesives, the preparation and dilution of the adhesive solution are crucial steps to ensure final product quality and production efficiency. The main components of water-based pressure-sensitive adhesives are typically water-soluble polymers, such as acrylic copolymers and polyurethanes. These polymers have high viscosity in their liquid state and often require dilution with appropriate amounts of solvent or water during production to ensure smooth flow and suitable coating properties. However, existing dilution equipment typically faces the following technical challenges:

[0003] Uneven dilution: In existing dilution devices, the mixing of diluent and adhesive is often uneven, resulting in inconsistent viscosity and properties of the adhesive in different areas, which affects the final coating effect and bonding quality.

[0004] Diluent control is difficult: Existing dilution devices lack precise diluent flow control, which means that in some cases the diluent flow cannot be precisely adjusted, resulting in inaccurate dilution of the adhesive and failure to meet the fine requirements of the production process.

[0005] Low mixing efficiency: Existing equipment often fails to achieve ideal mixing results when mixing adhesive and diluent. Low mixing efficiency can lead to a prolonged dilution process and is prone to producing foam or uneven mixing, affecting the final properties of the adhesive.

[0006] To address the aforementioned issues, existing technologies urgently require a new dilution device capable of rapidly and uniformly mixing the diluent with the water-based pressure-sensitive adhesive, while precisely controlling the dilution ratio, improving stirring efficiency, and reducing potential instability during production. Furthermore, the device should have a simple and easy-to-maintain structure, be able to operate stably for extended periods, and meet the demands of large-scale production. Summary of the Invention

[0007] This utility model relates to a dilution device, which is particularly suitable for the dilution and stirring in the production process of water-based pressure-sensitive adhesives and weather-resistant high-adhesion paper pressure-sensitive adhesives. It aims to solve the problems of uneven dilution, difficulty in flow control, and low stirring efficiency in the prior art.

[0008] The dilution device of this utility model includes: a raw material cylinder, a mixing vortex, a lifting guide seat, and multiple components that cooperate with it. The specific structure and function are as follows:

[0009] The raw material cylinder is used to store the water-based pressure-sensitive collagen solution. The raw material is added to the cylinder through the raw material filling port. This part has a simple structure, facilitating the storage and initial input of the raw material.

[0010] The mixing vortex is the core component of the device, used to mix and stir the water-based pressure-sensitive collagen solution with the diluent. The surface of the mixing vortex has a dilution inlet, through which dilution water is added into the device. The vortex channel guides the diluent in a spiral direction, ensuring thorough swirling mixing with the collagen solution and guaranteeing uniformity in the dilution process.

[0011] The lifting guide is fixedly installed on the top of the mixing drum, and a dispersing screen is installed on its inner side, with a swirl guide fixedly installed on the inner side of the screen. The lifting guide and the dispersing screen work together to further disperse and swirl the diluted liquid as it passes through, ensuring that the diluted liquid is evenly and thoroughly mixed with the adhesive.

[0012] The disperser is installed at the bottom of the raw material cylinder cavity and has a rotating function, which can effectively stir the water-based pressure-sensitive adhesive liquid and prevent the raw material from settling. The top of the disperser is connected to the lifting shaft through a shaft, forming a synergistic effect of lifting and stirring systems to ensure high efficiency in mixing and stirring.

[0013] To prevent the water-based pressure-sensitive adhesive from adhering and agglomerating during the mixing process, the inner sides of the mixing vortex drum, vortex channel, and raw material cylinder are all equipped with an anti-stick coating to reduce the adhesion of the adhesive to the inner wall of the equipment, ensuring smooth operation and efficient dilution of the equipment.

[0014] This invention optimizes the dilution and mixing process of the adhesive solution through a reasonable structural design. After the raw materials are stirred by the disperser in the raw material cylinder, dilution water is introduced through the dilution water inlet, guided by the vortex channel to form a vortex, and then the interaction between the dispersing screen in the lifting guide seat and the vortex guide ensures uniform mixing of the diluent and the adhesive solution. This device can effectively improve dilution efficiency, reduce operation difficulty, and adapt to the production needs of different types of water-based pressure-sensitive adhesive solutions.

[0015] The advantages of this utility model are:

[0016] Highly efficient dilution: Through swirling and dispersion mixing, the adhesive and diluent are effectively mixed uniformly, avoiding uneven dilution.

[0017] Precise control: The device can adjust the amount of dilution water added as needed to achieve precise control of the dilution ratio.

[0018] Reduced adhesion: The design of the inner wall anti-stick coating greatly reduces the adhesion of adhesive liquid, extending the service life of the equipment.

[0019] Easy to operate: The device has a simple structure and is easy to maintain and operate, and can meet the requirements of large-scale production.

[0020] Through the optimized design of the above structure and function, this utility model provides a high-efficiency and stable dilution device that can meet the high requirements for dilution effect and production efficiency in the production process of water-based pressure-sensitive adhesives and weather-resistant high-adhesion paper pressure-sensitive adhesives.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following is in conjunction with the appendix Figures 1-4 This invention describes a dilution apparatus provided by some embodiments of the present invention.

[0030] The structure of the dilution device of this utility model is shown in the attached figure, and the specific implementation method is as follows:

[0031] 1. Raw material cylinder 100 and its filling port 110:

[0032] The raw material cylinder 100 is used to store the water-based pressure-sensitive adhesive solution and is typically made of metal or plastic with good corrosion resistance. During production, operators add the adhesive solution to the raw material cylinder 100 through the raw material filling port 110. The raw material filling port 110 can be equipped with an overflow prevention device to ensure that the raw material does not spill.

[0033] 2. Mixing rotary drum 200 and dilution inlet 210:

[0034] The mixing vortex 200 is one of the core components of this device, and its main function is to contain and mix the raw material liquid and the diluent liquid. The dilution water inlet 210 is located on the side of the mixing vortex 200 and is usually connected to the dilution water source via a pipe. The dilution water enters the mixing vortex 200 through this inlet, helping to reduce the viscosity of the adhesive liquid. The vortex channel 211 is spiral-shaped. As the water liquid is injected, it flows along the spiral direction of the vortex channel 211 and is guided into the raw material cylinder 100, thereby achieving uniform mixing of the diluent and the adhesive liquid.

[0035] 3. Disperser 120 and lifting shaft 220:

[0036] The disperser 120 stirs the raw materials through rotation, and its bottom end is installed at the bottom of the raw material cylinder 100. To achieve efficient stirring, the disperser 120 is connected to the lifting shaft 220 via a shaft 130. The upper and lower ends of the shaft 130 are fixedly connected to the upper end of the disperser 120 and the lower end of the lifting shaft 220, respectively, ensuring that the disperser 120 and the lifting shaft 220 can work together to improve the stirring effect.

[0037] 4. Lifting guide seat 300 and its dispersing mesh disk 310 and vortex guide port 320:

[0038] The lifting guide seat 300 is fixedly installed on the top surface of the mixing drum 200. A dispersing screen 310 is installed inside the dispersing screen 310, and a swirl guide 320 is fixed inside the dispersing screen 310. The surface of the dispersing screen 310 is designed with multiple densely distributed mesh holes, ensuring thorough dispersion of the water-based pressure-sensitive adhesive as it passes through the screen. Subsequently, the diluent flows upward in a spiral shape through the swirl guide 320, further promoting the mixing and dilution process of the adhesive. The rotation direction of the swirl guide 320 is consistent with the rotation direction of the lifting shaft 220, ensuring efficient mixing of the diluent and the adhesive.

[0039] To reduce the adhesion and accumulation of adhesive inside the equipment, the inner walls of the raw material cylinder 100, the mixing swirl cylinder 200, and the surface of the swirl channel 211 are all coated with an anti-stick coating. This coating material has excellent anti-adhesion properties, effectively reducing adhesive residue, ensuring smooth operation of the equipment, and extending its service life.

[0040] Specifically, a conical dispersing screen 310 is fixedly installed on the inner side of the lifting guide seat 300, and a swirl inlet 320 is fixedly installed on the inner side of the dispersing screen 310. The bottom end of the disperser 120 is rotatably mounted on the bottom surface of the inner cavity of the raw material cylinder 100, and the upper and lower ends of the shaft 130 are fixedly connected to the ends of the disperser 120 and the lifting shaft 220, respectively. The dispersing screen 310 is conical and has several densely distributed mesh holes on its surface for dispersing and mixing the diluent. The disperser 120, shaft 130, lifting shaft 220, and swirl inlet 320 are located at the axis of the raw material cylinder 100 and the mixing swirl cylinder 200.

[0041] Dilution process:

[0042] During the dilution process, the raw material inlet 110 is used to add the water-based pressure-sensitive adhesive into the raw material cylinder 100. Subsequently, dilution water flows into the mixing vortex cylinder 200 through the dilution water inlet 210. The dilution water enters the raw material cylinder 100 in a spiral direction along the vortex channel 211. Through the stirring action of the disperser 120, the adhesive and the dilution water are mixed and the viscosity is rapidly reduced. As the lifting shaft 220 rotates, the mixed diluted liquid passes through the dispersing screen 310, and then through the vortex guide 320 before finally being discharged from the outlet 400. This process ensures rapid and uniform dilution of the adhesive.

[0043] Operation and maintenance:

[0044] This device features a simple structure and is easy to operate. During normal production, operators only need to periodically check the operation of each component, especially ensuring the raw material inlet 110, dilution inlet 210, and outlet 400 are unobstructed. The equipment employs an anti-stick coating design, reducing adhesive adhesion and thus simplifying cleaning and maintenance.

[0045] Workflow

[0046] Adding raw materials: The operator injects the water-based pressure-sensitive collagen into the raw material cylinder 100 through the raw material filling port 110.

[0047] Inject dilution water: Add dilution water into the mixing vortex drum 200 through dilution water inlet 210. The water enters the adhesive under the guidance of the vortex channel 211.

[0048] Stirring and mixing: The dilution water is thoroughly stirred with the adhesive solution through the disperser 120, while the lifting shaft 220 drives the rotation of the mixture to promote mixing.

[0049] Dispersion and swirling: The mixed liquid is further dispersed and swirled through the dispersion mesh 310 and swirling inlet 320 to ensure dilution effect.

[0050] Liquid discharge: The final diluted liquid is discharged from the outlet 400, completing the dilution process.
