Description

Technical Field

[0001] This invention relates to the field of hot melt coating production technology, specifically to a mixing device and method for hot melt coating production. Background Technology

[0002] Hot melt coatings emerged with industrial and infrastructure development. They melt and cool at a specific temperature to form a solid coating. Initially used mainly for road markings, their applications expanded to industrial protection, architectural decoration, and many other fields due to improvements in formulation and process. They are of great significance for transportation infrastructure construction and are gradually gaining popularity in high-tech industries. With increasingly stringent environmental regulations, hot melt coatings are striving to innovate and move towards green and low-pollution practices to meet the needs of sustainable development and continue to play a key role in many industries.

[0003] Hot melt coating production mixing equipment often uses a ribbon agitator to mix materials inside the tank. The internal ribbon is mounted on the agitator shaft, and the motor drives the shaft to rotate the ribbon. The inner ribbon pushes the material to both sides, while the outer ribbon pushes it back to the center, resulting in extensive mixing of materials. Furthermore, due to friction between the ribbon and the material, as well as the falling and rolling of the material, multi-directional motion mixing is achieved, ensuring that all components of the coating are evenly mixed.

[0004] When the mixing device for hot melt coating production is heated, the heat distribution is uneven, the temperature difference inside the tank is large, and the quality stability of the coating is damaged; insufficient stirring makes it difficult for the materials to be thoroughly mixed, and the composition distribution is uneven; the feeding system cannot accurately control the raw material ratio, and the product quality fluctuates; during filling, the high temperature of the material causes the barrel to deform, resulting in poor packaging effect, and the coating may also deteriorate due to heat, which not only increases costs and causes waste, but also hinders efficient production and quality assurance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mixing device and method for hot melt coating production, which solves the problems of uneven heating, insufficient stirring, inaccurate feeding, and barrel deformation caused by high temperature during filling, thus affecting quality, cost, and production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for producing hot melt coatings, comprising:

[0007] Tank structure, used to contain raw materials and mixtures and provide a mixing space;

[0008] The support mechanism is located on the outside of the tank body and is used to support the tank body and its auxiliary components;

[0010] The stirring mechanism is located inside the tank body and is used to thoroughly stir and mix the raw materials evenly.

[0011] The cooling mechanism is located on the lower side of the tank body and is used to cool down the material to be filled.

[0012] The stirring mechanism includes a motor three, which is located on the upper side of the support mechanism. The output end of the motor three is provided with a rotating shaft two, and the rotating shaft two is provided with a dispersing disc, a turbine blade and an anchor blade from top to bottom.

[0013] Preferably, the tank structure includes a mixing tank support, a mixing tank is provided on the top of the mixing tank support, a second mounting plate is provided on the lower part of the mixing tank support, and a discharge mechanism is provided on the top of the second mounting plate.

[0014] Preferably, the support mechanism includes legs, which are disposed on the outside of the tank body mechanism. A mounting plate is provided on the top of each leg, and a triangular plate is provided on the bottom of each leg.

[0015] Preferably, the batching mechanism includes a square box, with multiple square boxes arranged on the top of the mounting plate. Each square box has a funnel at its bottom and a motor at its top. Each motor has a rotating shaft at its output end, and multiple stirring rods are arranged on the outer side of each rotating shaft. Each square box also has multiple cylinders at its top, and each cylinder has a motor with a screw conveyor at its top. Each cylinder has a cylinder with a second outer side. The funnels penetrate the top of the mixing tank, and a liquid supply pipe is provided at the front of the mixing tank.

[0016] Preferably, the cooling mechanism includes a water tank and a cylindrical tube. The water tank is located on the lower side of the mounting plate, and the cylindrical tube is located on the lower part of the mounting plate. A water pump is installed on the outside of the water tank. The input end of the water pump is connected to the water tank through a pipe, and the output end of the water pump is connected to the inlet of the cylindrical tube through a pipe. The outlet of the cylindrical tube is connected to the water tank through a pipe. Water inlet pipes are installed on the outside of the water tank. A serpentine tube is installed inside the cylindrical tube, and the two ends of the serpentine tube are respectively connected to the two ends of the heat dissipation pipe.

[0017] Preferably, the discharge mechanism includes an L-shaped cylinder, which is disposed at the lower end of the mixing tank. A motor is disposed at the top of the mounting plate 2, and the output end of the motor 4 passes through the L-shaped cylinder and is provided with an auger blade 2.

[0018] Preferably, the outside of the mixing tank has an insulation layer, and a heating pipe is provided between the insulation layer and the mixing tank.

[0019] Preferably, the third motor is mounted on the upper side of the first mounting plate.

[0020] Preferably, the heat dissipation pipe is disposed on the outside of the L-shaped cylinder and is in contact with the L-shaped cylinder.

[0021] The present invention also provides a mixing method for producing hot melt coatings, comprising the following steps:

[0022] S1. The batching mechanism starts to operate. Motor 1 drives the rotating shaft 1 to rotate at high speed. The stirring rod pre-stirs the raw materials in the cylinder 1 to make them mixed and loose. Then, motor 2 drives the auger blade 1 to put the pre-stirred raw materials into the mixing tank through the funnel in a precise ratio to ensure that the raw material ratio is accurate and consistent.

[0023] S2. The heating tube is started to heat the material in the mixing tank to a specific temperature range. At the same time, the motor drives the two rotating shafts to rotate, the dispersion disc disperses the additives evenly, the turbine blades shear and disperse the material, and the anchor blades push the material at the bottom of the tank to turn over, so as to achieve full and uniform mixing of the raw materials.

[0024] S3. After mixing is completed, motor four drives auger blade two to rotate, and the material is discharged through the L-shaped cylinder to provide a stable material flow for subsequent processes.

[0025] S4. The cooling mechanism is activated. Water in the water tank flows into the serpentine tube inside the cylinder under the drive of the water pump. After absorbing heat, it is dissipated through the heat dissipation tube to reduce the temperature of the material on the outside of the L-shaped cylinder, thereby cooling the material to be filled and ensuring the integrity of the packaging and the reliability of the coating quality.

[0026] S5. The liquid supply pipe can provide an appropriate amount of liquid to the mixing tank according to the production process requirements or the material state, to help adjust the performance indicators such as the viscosity and flowability of the coating, improve product diversity and adaptability, and the various components of the support mechanism work together, the legs bear the load, the mounting plate one provides the installation plane, the triangular plate enhances stability, and the mixing tank support and mounting plate two assist in the installation and positioning of related components, ensuring the efficient and stable operation of the device.

[0027] This invention provides a mixing apparatus and method for producing hot-melt coatings. It offers the following advantages:

[0028] 1. This invention precisely controls and adds raw materials through a batching mechanism. For example, motors one and two drive the stirring rod for premixing and the auger blade for precise material feeding. During mixing, motor three drives the dispersion disc, turbine blade, and anchor blade to disperse additives at the microscopic level and agitate materials at the macroscopic level, ensuring that the raw materials are fully mixed, guaranteeing stable product quality, avoiding problems with proportioning and mixing, improving production efficiency and product consistency, and laying the foundation for high-quality coating production.

[0029] 2. This invention precisely controls the temperature of the material inside the mixing tank through the heating tube to ensure that the production requirements are met. In the cooling mechanism, the heat dissipation tube absorbs the heat of the L-shaped cylindrical material through the coolant and transfers it to the serpentine tube. The water pump cools the serpentine tube with water, effectively preventing the filling tank from deforming and the coating from deteriorating, maintaining the integrity of the packaging and the reliability of the quality. It can also flexibly adjust the temperature according to production, adapt to diverse needs, and ensure the smooth progress of the process.

[0030] 3. This invention integrates multiple functions into one device, with each mechanism working seamlessly together, optimizing the production process, reducing floor space and costs, facilitating daily maintenance, reducing the probability of failure, ensuring continuous and stable production, improving overall efficiency, enhancing product market competitiveness and adaptability, and helping enterprises achieve efficient production and operation.

Detailed Implementation

[0040] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides a mixing device for producing hot melt coatings, comprising:

[0042] Tank structure 2 is used to contain raw materials and mixtures and provide a mixing space. Tank structure 2 includes a mixing tank support 202. A mixing tank 201 is set on the top of the mixing tank support 202. Mounting plates 203 are set on the lower part of the mixing tank support 202. There is an insulation layer 8 on the outside of the mixing tank 201. A heating pipe 7 is set between the insulation layer 8 and the mixing tank 201. The mixing tank 201 is stably supported by the mixing tank support 202. The external insulation layer 8 and the heating pipe 7 work together to control the internal temperature environment, greatly reduce the heat loss to the outside, and make the material heated very evenly in the tank. This effectively ensures the high stability of the quality during the coating production process and completely avoids the situation where the coating performance is inconsistent due to unstable temperature fluctuations. This lays a solid foundation for the production of high-quality hot melt coatings.

[0043] The top of the mounting plate 203 is equipped with a discharge mechanism 6, which includes an L-shaped cylinder 601. The L-shaped cylinder 601 is located at the lower end of the mixing tank 201. The top of the mounting plate 203 is equipped with a motor 602. The output end of the motor 602 passes through the L-shaped cylinder 601 and is equipped with an auger blade 603. The motor 602 of the discharge mechanism 6 drives the auger blade 603 to rotate stably inside the L-shaped cylinder 601, which can realize the stable discharge of materials. After the mixing process is completed, the materials are pushed out through the L-shaped cylinder 601 at a stable flow rate and speed under the orderly push of the auger blade 603. This process is extremely smooth and stable, providing convenient connection conditions for subsequent filling and other processes, significantly improving the production efficiency and continuity of the entire production process, reducing production interruptions and delays caused by unstable discharge, and further improving production efficiency.

[0044] The support mechanism 1 is located on the outside of the tank body mechanism 2 and is used to support the tank and its auxiliary components. The support mechanism 1 includes a support leg 103, which is located on the outside of the tank body mechanism 2. The top of the support leg 103 is provided with a mounting plate 101, and the bottom of the support leg 103 is provided with a triangular plate 102. The support leg 103 of the support mechanism 1 serves as the main load-bearing component, which firmly supports the structure of the entire device. The mounting plate 101 provides a very flat and stable mounting surface for the related components above. The triangular plate 102 cleverly enhances the connection between the support leg 103 and the ground or mounting foundation. The three work together to resist various vibration interferences and lateral forces that may be generated during the operation of the device, ensuring that the entire device is always in a stable and reliable operating state, significantly reducing the wear and fatigue of equipment components caused by vibration, effectively extending the overall service life of the equipment, and reducing the maintenance cost and frequency of the equipment.

[0045] The batching mechanism 3 is located on top of the support mechanism 1 and is used to precisely adjust and dispense the raw materials. The batching mechanism 3 includes a square box 301, and multiple square boxes 301 are located on top of the mounting plate 101. Each square box 301 has a funnel 302 at its bottom and a motor 303 at its top. Each motor 303 has a rotating shaft 304 at its output end, and multiple stirring rods 305 on the outside of the rotating shaft 304. Each square box 301 also has multiple cylinders 306 at its top, and each cylinder 306 has a motor 307 at its top. Each motor 307 has an auger blade 309 at its output end, and cylinders 308 on the outside of each cylinder 306. The funnels 302 all penetrate the top of the mixing tank 201. A liquid supply pipe 9 is located at the front of the mixing tank 201. The motor 303 drives the rotating shaft 304 and the stirring rods 305 to fully mix the raw materials in the cylinders 306. Pre-mixing ensures the raw materials are initially homogeneous. Then, motor 2 (307) precisely drives auger blade 1 (309) to stably and efficiently feed the pre-mixed raw materials into mixing tank 201 through funnel 302 according to a highly precise set ratio. This ensures a high degree of consistency in the raw material ratio of each batch of hot melt coatings, accurately meeting the strict production process standards. This effectively guarantees the reliability and stability of product quality, reducing product quality defects and scrap rates caused by raw material ratio errors. Liquid supply pipe 9 can replenish an appropriate amount of liquid into mixing tank 201 in a timely and precise manner according to specific production process requirements or actual changes in the material's state during mixing. This effectively assists in adjusting a series of key performance indicators such as the coating's viscosity and fluidity, thereby achieving flexible control over the coating's performance and expanding the product's application range and functional characteristics.

[0046] The stirring mechanism 4 is located inside the tank mechanism 2 and is used to fully stir and uniformly mix the raw materials. The stirring mechanism 4 includes a motor 401, which is located on the upper side of the support mechanism 1. The output end of the motor 401 is equipped with a rotating shaft 402. The rotating shaft 402 is equipped with a dispersion disc 403, a turbine blade 404, and an anchor blade 405 from top to bottom. The dispersion disc 403 can quickly and uniformly disperse the materials added later in the tank. The turbine blade 404, with its strong shearing action and unique shape structure, performs deep and efficient shearing and dispersion operations on the materials, which can effectively break up any agglomerates that may exist in the materials and further promote deep mixing between different components at the microscopic level. The anchor blade 405 rotates continuously and stably at the bottom of the tank, providing sufficient upward turning power for the materials at the bottom of the tank, effectively preventing the accumulation of materials at the bottom and the problem of uneven mixing.

[0047] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 7 With appendix Figure 8 The cooling mechanism 5 is located on the lower side of the tank body 2 and is used to cool the material to be filled. The cooling mechanism 5 includes a water tank 501 and a cylindrical shell 504. The water tank 501 is located on the lower side of the mounting plate 203, and the cylindrical shell 504 is located on the lower part of the mounting plate 203. A water pump 503 is located on the outside of the water tank 501. The input end of the water pump 503 is connected to the water tank 501 through a pipe, and the output end of the water pump 503 is connected to the water inlet of the cylindrical shell 504 through a pipe. The outlet of the cylindrical tube 504 is connected to the water tank 501 via a pipe. Water inlet pipes 502 are installed on the outside of the water tank 501. A serpentine tube 506 is installed inside the cylindrical tube 504, with each end of the serpentine tube 506 connected to the two ends of a heat dissipation pipe 505. The cooling mechanism 5, through the organic combination and coordinated operation of the water tank 501, water pump 503, cylindrical tube 504, and the internal serpentine tube 506 and heat dissipation pipe 505, can efficiently cool the material to be filled. When the material is fully mixed and about to enter the filling process, the cooling mechanism 5 is quickly activated. Water in the water tank 501 flows into the serpentine tube 506 inside the cylinder 3 504 under the strong drive of the water pump 503. At this time, the heat dissipation tube 505, because it contains coolant, is in close contact with the L-shaped cylinder 601 and can fully absorb the heat of the material in the L-shaped cylinder 601. Then, the heat is transferred to the serpentine tube 506, which exchanges heat with the water inside the cylinder 3 504. Finally, the temperature of the material on the outside of the L-shaped cylinder 601 is reduced quickly and effectively, which effectively prevents a series of problems such as deformation of the filling barrel and deterioration of the coating itself caused by excessive material temperature. This effectively ensures the integrity of the product packaging and the reliability of the coating quality. At the same time, the cooling mechanism 5 can also flexibly and accurately adjust the cooling intensity according to different needs in the actual production process to better adapt to diverse production scenarios and process requirements, providing strong support and guarantee for the smooth operation of the production process.

[0048] Please see the appendix Figures 1-8 The present invention also provides a mixing method for producing hot melt coatings, comprising the following steps:

[0049] S1. The batching mechanism 3 starts the operation process first. Motor 1 303 drives the rotating shaft 1 304 to rotate at high speed. The connected stirring rod 305 then carries out a thorough pre-mixing operation on various raw materials in the cylinder 1 306. Under the continuous stirring of the stirring rod 305, the raw materials gradually mix and loosen. Any lumps that may have existed are effectively broken up, laying a good foundation for subsequent precise addition. Then, motor 2 307 precisely drives the auger blade 1 309 to operate stably. The pre-mixed and loosely mixed raw materials are added to the mixing tank 201 in an orderly manner through the funnel 302 according to the pre-set precise ratio. Thanks to the stable output of motor 2 307 and the efficient conveying of auger blade 1 309, the raw material ratio of each batch of hot melt coating can be guaranteed to be highly accurate and consistent, providing a solid material ratio basis for producing products with stable quality and reliable performance.

[0050] S2. Once the raw materials are successfully added to the mixing tank 201, the heating tube 7 immediately starts and evenly dissipates heat, continuously heating the materials inside the mixing tank 201. Under the action of the heating tube 7, the material temperature gradually rises until it reaches the specific temperature range required for hot melt coating production. During this heating process, the motor 3 401 synchronously drives the rotating shaft 2 402 to rotate powerfully. The dispersing disc 403 located on the rotating shaft 2 402 then rotates at high speed. With its unique structural design and high-speed motion characteristics, it quickly and evenly disperses the additives added later into the main material, effectively avoiding additive agglomeration and adverse effects on coating performance. At the same time, the turbine blade 404, with its... Its unique shape and powerful motor enable efficient shearing and dispersion of materials, successfully breaking down any agglomerates and further promoting deep mixing of different components at the microscopic level. Meanwhile, the anchor blade 405 rotates continuously and stably at the bottom of the tank, providing ample upward tumbling power for the materials at the bottom, effectively preventing uneven mixing caused by material deposition at the bottom. Through the close synergistic operation of the dispersion disc 403, turbine blade 404, and anchor blade 405, the raw materials are successfully and evenly mixed at both the macroscopic and microscopic levels, ensuring the quality stability and superior performance of the hot melt coating and providing high-quality mixed materials for subsequent processes.

[0051] S3. After the mixing process is successfully completed, motor 4 602 starts to drive auger blade 2 603 to rotate at a constant speed. At this time, the material that has been fully mixed and meets the process requirements is pushed out of the L-shaped cylinder 601 in an orderly manner under the stable push of auger blade 2 603. This discharge process is extremely smooth and the flow rate is stable, which can provide a continuous and stable material flow for subsequent filling and other processes. It effectively avoids production interruption or delay due to unstable discharge, greatly improves the production efficiency and continuity of the entire production process, and enables seamless connection between processes, further improving production efficiency and product quality stability.

[0052] S4. As the material discharge process progresses, the cooling mechanism 5 is activated in a timely manner. Water in the water tank 501, driven by the powerful water pump 503, rapidly flows into the serpentine tube 506 inside the cylinder 604. Due to the special shape design of the serpentine tube 506, the contact area between the water and the tube wall is increased, allowing it to fully absorb heat. Simultaneously, the heat dissipation tube 505, which is in close contact with the L-shaped cylinder 601, begins to play a crucial role. The heat dissipation tube 505 is filled with coolant, which can quickly absorb the heat from the material outside the L-shaped cylinder 601 and transfer the heat to the serpentine tube 506, ultimately achieving rapid and effective cooling. The low temperature of the material on the outside of the L-shaped cylinder 601 ensures that the material can be filled at a suitable temperature, preventing a series of problems such as deformation of the filling barrel and deterioration of the coating itself caused by excessive material temperature. This effectively guarantees the integrity of the product packaging and the reliability of the coating quality. At the same time, the cooling mechanism also has the ability to flexibly adjust the cooling intensity. According to different needs in the actual production process, the cooling speed and effect can be precisely controlled by adjusting the power of the water pump 503, etc., to better adapt to diverse production scenarios and process requirements, providing strong support and guarantee for the smooth operation of the production process.

[0053] S5. Throughout the production process, the liquid supply pipe 9 plays a crucial role in flexible control. It can supply the appropriate amount of liquid to the mixing tank 201 in a timely and precise manner according to specific production process requirements, such as adjusting key performance indicators like viscosity and flowability of the coating, or based on the actual changes in the material's state during mixing. This supplementary liquid effectively interacts with the materials inside the tank, assisting in adjusting the coating's performance, thereby achieving flexible control over the coating's properties. This expands the product's application range and functional characteristics, enabling it to better meet the specific needs of different customers in different application scenarios, enhancing the product's competitiveness and adaptability in the market. Simultaneously, the various components of the support mechanism 1 also work together. The support leg 103, as the main load-bearing component, steadily supports the weight of the entire device, ensuring the stability of the device during operation. The mounting plate 101 serves as the upper component for the batching mechanism 3, etc. A flat and stable mounting surface is provided, ensuring the accuracy and reliability of the installation of each component. The triangular plate 102 enhances the connection stability between the support leg 103 and the ground or mounting foundation, effectively resisting the lateral forces and vibrations that may be generated during the operation of the device, preventing the device structure from deforming or the components from loosening due to external interference, and further ensuring the stability and safety of the overall structure of the device. The mixing tank bracket 202 provides reliable suspension and positioning support for the mixing tank 201, enabling it to maintain a stable position and state during the mixing process. The mounting plate 203 plays a good role in bearing and assisting the installation of related components such as the discharge mechanism 6 at the bottom, providing a solid foundation for the coordinated work of each component. The various components cooperate with each other to form an organic whole, jointly ensuring the efficient and stable operation of the entire hot melt coating production mixing device, ensuring the smooth progress of the production process and the stable and reliable quality of the product.

10. A mixing method for producing hot-melt coatings, comprising the mixing apparatus for producing hot-melt coatings according to any one of claims 1-9, characterized in that, Includes the following steps: S1. The batching mechanism (3) starts to operate. Motor 1 (303) drives the rotating shaft 1 (304) to rotate at high speed. The stirring rod (305) pre-stirs the raw materials in the cylinder 1 (306) to make them loosely mixed. Then, motor 2 (307) drives the auger blade 1 (309) to put the pre-stirred raw materials into the mixing tank (201) through the funnel (302) in a precise ratio to ensure that the raw material ratio is accurate and consistent. S2. The heating tube (7) is started to heat the material in the mixing tank (201) to a specific temperature range. At the same time, the motor (401) drives the rotating shaft (402) to rotate. The dispersing disc (403) disperses the additives evenly. The turbine blade (404) shears and disperses the material. The anchor blade (405) pushes the material at the bottom of the tank to turn over, so as to achieve full and uniform mixing of the raw materials. S3. After mixing is completed, motor four (602) drives auger blade two (603) to rotate, and the material is discharged through L-shaped cylinder (601) to provide a stable material flow for subsequent processes; S4. The cooling mechanism (5) is started. Water in the water tank (501) flows into the serpentine tube (506) inside the cylinder three (504) under the drive of the water pump (503). After absorbing heat, it is dissipated through the heat dissipation pipe (505) to reduce the temperature of the material outside the L-shaped cylinder (601), thereby cooling the material to be filled and ensuring the integrity of the packaging and the reliability of the coating quality. S5. The liquid supply pipe (9) can provide an appropriate amount of liquid to the mixing tank (201) according to the production process requirements or the material status adjustment, to help adjust the performance indicators such as the viscosity and fluidity of the coating, and improve the product diversity and adaptability. In addition, the components of the support mechanism (1) work together, the support leg (103) bears the load, the mounting plate one (101) provides the installation plane, the triangular plate (102) enhances the stability, and the mixing tank support (202) and the mounting plate two (203) assist in the installation and positioning of related components, ensuring the efficient and stable operation of the device.
