Description

Technical Field

[0001] The invention belongs to the technical field of coating preparation, in particular to a thermoplastic floor coating preparation system. Background Art

[0002] Floor paint is made up of a variety of different substances through many production processes such as mixing, dissolving, and dispersing. It is mainly made of oil, wood, color, solvent, etc., and is mainly divided into decorative floor paint, heavy-duty anti-corrosion floor paint, heavy-load resistant floor paint, etc. The main base materials include polyurethane resin: it is made of isocyanate and polyester, polyether, epoxy resin, castor oil or its processed products containing hydroxyl thermoplastic polymer acetate butyrate cellulose and other formulas to make many varieties of polyurethane coatings; epoxy resin: when epoxy resin is used in floor coating, epoxy resin is used as seamless floor coating material on the floor, and it is the main base material of water-emulsion exterior wall coating; acrylic resin: it is composed of resins made by copolymerization of acrylates and other olefinic monomers. By selecting different resin structures, different formulas, production processes, solvents and additives, it can be made into solvent-based, water-based, powder-based and solvent-free types.

[0003] The composition of floor coatings is relatively complex. The main ingredients are epoxy resin, phenolic resin and acrylic acid, which can be divided into thermosetting and thermoplastic according to their thermal properties. When producing thermoplastic floor coatings, the materials are mixed in the process because the materials are relatively viscous at room temperature. As a result, it is difficult for the stirring rod to separate the matrix material during the mixing process, which makes it difficult for additives, pigments and other auxiliary materials to be evenly dispersed in the substrate, resulting in quality problems such as floating color in the produced floor coatings, thereby reducing the quality of the floor coatings. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention proposes a thermoplastic floor coating preparation system. The present invention is mainly used to solve the problem that the floor coating quality is reduced due to uneven stirring caused by the viscosity of the material during the production process.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a thermoplastic floor coating preparation system, comprising a fixing frame, a heat stirring component, an atomizing component, a flow channel and an air flotation mixing component; the heat stirring component is arranged on the upper part of one end of the fixing frame; the heat stirring component is used to stir and mix the heat-resistant raw materials; the atomizing component is arranged at one end of the heat stirring component, and the atomizing component and the heat stirring component are connected; the flow channel is arranged at one end of the atomizing component; the flow channel is connected to the outlet end of the atomizing component; the flow channel is fixedly connected to the fixing frame; a refrigerated gas medium is introduced into the end of the flow channel through a pipeline to freeze the raw materials; the air flotation mixing component is arranged at one end of the flow channel away from the atomizing component; the air flotation mixing component is used to mix the treated heat-resistant raw materials with non-heat-resistant raw materials;

[0006] The atomization component includes an atomization pump, an atomization nozzle, a connecting piece and an atomization bin; the atomization pump is arranged on the upper part of the fixed frame; the atomization pump is fixedly connected to the fixed frame; the atomization bin is arranged at one end of the atomization pump; the atomization bin is fixedly connected to the fixed frame; a connecting piece is arranged inside the atomization bin; the connecting piece is fixedly connected to the atomization bin; the atomization pump is connected to the connecting piece; the atomization nozzles are evenly spaced on one side of the connecting piece; the atomization nozzle is fixedly connected to the connecting piece; the connecting piece is connected to the atomization nozzle.

[0007] During operation, heat-resistant raw materials such as substrates and pigments are put into the hot stirring component. Since the hot stirring component has a heating function, the mixed raw materials can be stirred during the stirring process. Since the substrate involved is a thermoplastic substrate, the viscosity of the raw materials can be reduced after the material is heated, making it easier for the raw materials to be separated by the stirring rod, so that the materials can be more evenly dispersed in the substrate. The mixed raw materials after stirring are then transported to the atomizing pump, which pressurizes the raw materials through the atomizing pump and then passes through the atomizing nozzle (the external atomizing nozzle is used, and the raw materials are sprayed a certain distance outside the atomizing nozzle, and then a high-pressure airflow is sprayed from the atomizing nozzle, so that the mixed raw materials are dispersed into a mist structure; since the mixed raw materials also have a certain viscosity, the external atomization method is used to make the mixing space larger, which can reduce the risk of aggregation after atomization, thereby improving the uniformity of atomization) The raw materials are sprayed out to make the mixed raw materials form mist, and then the atomized mixed raw materials enter the flow channel. Since the flow channel is filled with cooling gas, the mist mixed material freezes during the flow channel to form powder particles, and then the powder particles enter the air flotation mixing component. After entering the mixing air flotation component, the non-heat-resistant raw material powder in the floor coating is put into the air flotation mixing component, and then the heat-resistant raw material powder and the non-heat-resistant material powder are mixed in the air flotation mixing component. Finally, the mixed raw materials are put into the heating equipment for heating and melting, and the production of the floor coating is completed. Since all the raw materials are in a powdery structure during the mixing process, the substrate does not need to be divided during the mixing process, and there is no need to overcome the problem of difficulty in division caused by the high viscosity of the substrate, thereby improving the mixing efficiency. At the same time, since the size of the powder particles is uniform, the mixing uniformity is improved, and the uniformity of the floor coating is improved.

[0008] Preferably, the hot stirring component includes a stirring chamber, a No. 1 motor, a connecting pipe joint, a hot stirring frame and a valve; the No. 1 motor is arranged on the upper part of the stirring chamber; the No. 1 motor is fixedly connected to the stirring chamber; the hot stirring frame is arranged inside the stirring chamber; the hot stirring frame is rotatably connected to the stirring chamber; the hot stirring frame is composed of a sheet-like stirring frame with a heating device inside; the side wall of the stirring chamber is hollow; air holes are evenly spaced on the inner side wall of the stirring chamber; the diameter of the air holes is 0.2-0.3mm; the connecting pipe joint is arranged on the outside of the stirring chamber; the connecting pipe joint is fixedly connected to the side wall of the stirring chamber; the connecting pipe joint is used to connect the air path device inside and outside the side wall of the stirring chamber; the valve is arranged at the bottom of the stirring chamber; the valve is fixedly connected to the stirring chamber; one end of the valve is communicated with the stirring chamber; the other end of the valve is connected to the inlet end of the atomizing pump.

[0009] During operation, during the stirring process of heat-resistant materials such as substrates, due to the high viscosity of the materials, the materials may adhere to the stirring rod during the stirring process. Compared with the stirring rod, the inner wall of the stirring chamber is often smooth, which will cause the stirring rod to exert a large force on the materials during the stirring process, while the friction resistance of the inner wall to the materials is small, which will cause the materials to slip relative to the inner wall, and the movement of the materials relative to the stirring rod is small, which will reduce the separation of the materials by the stirring rod, resulting in low stirring efficiency and affecting the uniformity of stirring. Therefore, by setting the side wall of the stirring chamber into a mesoporous structure and setting micro holes on the inside, the cavity inside the stirring chamber can be connected to the external negative pressure generating device through a connecting pipe joint during use, so that a cavity is formed in the cavity inside the stirring chamber, which can increase the resistance of the side wall inside the stirring chamber to the materials, thereby avoiding the material from slipping relative to the inner wall, thereby ensuring the relative movement between the stirring rod and the materials, thereby ensuring the separation of the substrate by the stirring rod, and thereby ensuring the uniform dispersion of the materials. At the same time, when discharging the materials, the connecting pipe joint can be connected to the material. The pipe joint is transferred to the positive air pressure equipment to blow it inward, so that a layer of air mold can be formed between the material and the inner wall, which can prevent the material from sticking, thereby improving the thoroughness of the material discharge and the neatness of the system; at the same time, during the stirring process, the air vent can be connected to the external high-pressure (more than 3 MPa) air source through the connecting pipe joint, and then the high-pressure airflow is continuously rushed into the inside during the stirring process, so that the high-pressure airflow can cut the raw materials, thereby improving the dispersion uniformity of the raw materials. At the same time, because the raw materials have a certain viscosity, after the airflow enters the mixed raw materials, bubbles will be formed inside the mixed raw materials. Because bubbles are generated inside the mixed raw materials, the raw materials have a certain looseness before atomization, and the difficulty of atomization can be reduced during atomization, thereby improving the uniformity of the mixed raw materials after atomization, thereby improving the uniformity of the floor coating and because the separation needs to be heated and melted later (it can be in a negative pressure state during the heating and melting process, thereby accelerating the elimination of bubbles), the bubbles will float up during the heating process to complete the elimination of bubbles.

[0010] Preferably, the flow channel includes a receiving section and an acceleration section; the receiving section is fixedly connected to the atomization chamber; an acceleration section is arranged on one side of the receiving section; the acceleration section is arranged perpendicular to the center line of the receiving section; a No. 1 fan is arranged on the upper part of the acceleration section; and the temperature outlet of the No. 1 fan is connected to the inside of the acceleration section.

[0011] During operation, since the mixed raw materials are in a molten state when they are sprayed out, the speed when they are just sprayed out is often relatively fast, and there is a risk of re-melting with the mixed raw materials that are already in an atomized state, thereby forming a mist mixture with larger particles, which will cause uneven particles of the mist mixture, thereby resulting in uneven production of floor coatings, and thus resulting in reduced quality of the floor coatings; therefore, in this solution, an acceleration section is provided in the flow channel, and a No. 1 fan is provided at the acceleration end, and then when the raw materials enter the acceleration section in the flow channel, the airflow blown out by the No. 1 fan can drive the mist raw materials to move faster, thereby preventing the subsequent sprayed raw materials from colliding with the previously sprayed raw materials. The mixed raw materials are mixed, thereby avoiding the re-melting of the mist particles, thereby improving the uniformity of the formed powder particles, thereby improving the uniformity of the floor coating; at the same time, because in the present scheme the acceleration section and the receiving section are arranged perpendicular to each other, the movement direction of the mist particles can be changed during acceleration, thereby further increasing the distance between the mist mixed raw materials sprayed in the front and rear time periods, thereby reducing the probability of collision between the mist raw materials, thereby reducing the probability of welding between the mist mixed raw materials, further ensuring the uniformity of the mist powder particles, further improving the uniformity of the floor coating, thereby improving the quality of the floor coating.

[0012] Preferably, the flow channel also includes a deceleration section; airflow pieces are evenly spaced on both sides of the deceleration section in the vertical direction; the airflow pieces are arranged in pairs; the connecting line between the paired airflow pieces is arranged at an angle; one of the paired airflow pieces is connected to an external blowing component to realize outward blowing; the other airflow is connected to an external suction device to realize outward suction; the airflow pieces blow out low-temperature gaseous medium; the temperature of the medium blown out by the airflow pieces gradually increases from one end close to the acceleration section to the other end; the temperature of the gas medium does not exceed -5°C.

[0013] During operation, after the mixed raw materials are atomized by the atomizing head, the formed mist particles are in a molten state. Under the action of surface tension, the mist particles will tend to be spherical. When the formed mist particles are spherical, the stacking angle of the formed powder will be smaller, and the surface smoothness will increase, which will increase the fluidity of the mist particles and make the powder easier to mix evenly. Therefore, the higher the sphericity of the powder during production, the more positive the effect on the quality of the floor coating. After being accelerated in the acceleration section, the atomized particles will move at a high speed, and the resistance encountered during the movement will cause the atomized particles to deform, which will reduce the sphericity of the atomized particles. Therefore, In this solution, a deceleration section is set inside the flow channel, and symmetrical airflow parts are set above and below the deceleration section, one of the airflow parts blows air and the other airflow part inhales air, thereby forming a flowing air curtain between the two pairs of airflow parts, and the air curtain is set at an angle, so that the atomized particles will encounter resistance in the opposite direction of movement when passing through the air curtain, thereby reducing the movement speed of the atomized particles. At the same time, since the air curtain flows with a frozen gas medium, the atomized particles will be quickly frozen and hardened on the surface passing through the air curtain, thereby avoiding the aggregation of particles caused by deceleration and causing sticking. Therefore, it is possible to avoid sticking while ensuring the sphericity, thereby improving the quality of the products produced by the system.

[0014] Preferably, the flotation mixing component includes an electrostatic additional component, a mixing bin, an air pump and a collecting piece; the outlet end of the flow channel is provided with an electrostatic additional component; the electrostatic additional component is used to add static electricity to the powder entering the mixing bin; the mixing bin is provided at one end of the flow channel; the mixing bin is fixedly connected to the fixed frame; the air pump is provided on one side of the mixing bin; the air pump is fixedly connected to the mixing bin; the outlet end of the air pump is fixedly connected to the upper end of the mixing bin; the inlet end of the air pump is connected to the lower end of the mixing bin; the inlet and outlet ends of the air pump are both connected to the interior of the mixing bin; a feed port and an air inlet are provided at the upper part of the mixing bin; the collecting piece is provided at the lower part of the mixing bin; the collecting piece is used to collect mixed materials; the collecting piece is electrically connected to an external electrostatic generating device.

[0015] During operation, the mist raw material is formed into powder after being frozen. Driven by the airflow, the raw material can enter the electrostatic additional component (it can be a strong electric field, which ionizes the internal gas medium to form electrons and positive ions. When the powder passes through, the positive ions and the powder are adsorbed to each other, so that the powder has the same charge; or a strong light wave irradiates a thin metal layer, so that the electrons in the metal are freed, so that the powder has the same charge). After passing through the electrostatic additional component, the powder particles have the same charge, which will cause the powders to repel each other, and then after entering the mixing chamber, The powder is not only driven by the airflow, but also affected by the repulsive force of the electric charge, which increases the irregularity of the movement of the powder particles, thereby improving the uniformity of mixing, thereby improving the uniformity of mixing between the raw materials of the floor coating, thereby improving the quality of the floor coating; at the same time, by electrically connecting the mobile phone component to the electrostatic generating device, and then aggregating the materials after mixing evenly, the collecting component is charged with an opposite charge to the powder particles, which will cause the powder particles to be attracted by the collecting component, and then the powder particles can be quickly gathered on the collecting component, thereby improving the efficiency of collection after mixing, thereby improving the production efficiency of the floor coating.

[0016] Preferably, elastic strips are arranged at intervals inside the mixing bin; one end of the elastic strip is fixedly connected to the mixing bin; and the deformation pressure of the elastic strip in the length direction is unevenly distributed.

[0017] During operation, by arranging elastic strips inside the mixing bin, when the air pump blows air into the mixing bin, the elastic strips will block the airflow, which will change the flow direction of the airflow, thereby increasing the turbulence of the airflow inside the mixing bin, and then increase the turbulence of the powder mixed inside, thereby improving the uniformity of powder mixing; at the same time, by arranging the deformation pressure of the elastic strips to be unevenly distributed (the thickness of the elastic strips can be set to be different at different locations, or a metal elastic sheet can be set inside the elastic strips to make the pressure limit of the deformation of the elastic strips different at different locations), when a larger airflow acts on the elastic strips, there will be Some parts will bend and deform, and the degree of bending and deformation is not the same, while some parts will not bend and deform, which will increase the path direction of the airflow acting on the elastic strip after the collision, and further increase the degree of turbulence of the airflow inside the mixing bin, thereby improving the mixing uniformity of the powder. At the same time, due to the elasticity of the elastic strip, when airflows of different sizes act at different times, the elastic strip will present different shapes, which will prevent the internal airflow from forming a regular airflow circulation inside the mixing bin, thereby avoiding the occurrence of uneven mixing of powders, thereby improving the mixing uniformity of the floor coating, and thereby improving the quality of the floor coating.

[0018] Preferably, a slide groove is provided on the mixing bin; the collecting piece is arranged inside the slide groove; and the collecting piece is slidably connected to the slide groove.

[0019] During operation, after the mixing and collection is completed, the powder material needs to be transferred to the heating device for heating. Since the powder is more likely to be disturbed by the airflow during the transfer process, it often causes more waste during the transfer process, and the dust will cause environmental pollution, which will harm the health of the operator. Therefore, in this solution, the collecting piece is set to be connected to the mixing bin in an assembled manner, and the dust material is collected by electrostatic adsorption. After the dust collection is completed, a relatively stable state will be formed between the collecting piece and the dust. Therefore, the collecting piece is directly taken out and transferred to the heating equipment for heating. The dust will be in a relatively stable state during the transfer process, which can reduce the loss of dust and reduce the pollution of dust to the environment.

[0020] Preferably, the cross-section of the hot stirring rack is elliptical; the outer surface of the hot stirring rack is provided with an anti-stick coating at both ends of the major axis of the ellipse; and the span of the anti-stick coating does not exceed 1 / 2 of the circumference of the ellipse.

[0021] During operation, since the hot stirring rack needs to heat the mixed material during the stirring process, it also needs to cut the mixed material. During cutting, the smaller the contact area between the cutting surface and the material, the smaller the resistance during cutting, and thus the higher the cutting efficiency. During heating, the larger the contact area between the stirring rack and the mixed material, the better, and thus the heating efficiency can be improved. Therefore, in this scheme, the cross-section of the hot stirring rack is set to an elliptical shape, so that the cutting surface can be reduced while ensuring a large contact area between the stirring rack and the material, thereby improving the cutting efficiency. At the same time, an anti-stick coating (such as a Teflon coating) is set at the position of the cutting surface of the hot stirring rack. Since the adhesion between the coating and the material is low, the resistance during cutting of the material can be reduced, thereby improving the stirring efficiency. At the same time, the span of the coating is controlled, so that when the stirring rack cuts the material, the adhesion resistance between the non-cutting surface and the material support can be maintained, so that a driving force is generated on the passing material during the cutting process, so that the flow of raw materials can be accelerated during the cutting process, thereby achieving a better mixing effect, thereby improving the uniformity and efficiency of mixing.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, heat-resistant raw materials such as substrates and pigments are put into a hot stirring component. Since the hot stirring component has a heating function, the mixed raw materials can be stirred during the stirring process. Since the substrate involved is a thermoplastic substrate, the viscosity of the raw materials can be reduced after the materials are heated, making it easier for the raw materials to be separated by the stirring rod, so that the materials can be more evenly dispersed in the substrate. The mixed raw materials after stirring are then transported to an atomizing pump, the raw materials are pressurized by the atomizing pump, and then the raw materials are sprayed out through an atomizing nozzle, so that the mixed raw materials form a mist. Then the atomized mixed raw materials enter the flow channel. Since the flow channel is filled with cooling gas, the mist mixed raw materials are cooled during the flow channel. The material is frozen to form powder particles, which then enter the air flotation mixing component. After entering the mixing air flotation component, the non-heat-resistant raw material powder in the floor coating is put into the air flotation mixing component, and then the heat-resistant raw material powder and the non-heat-resistant material powder are mixed in the air flotation mixing component. Finally, the mixed raw materials are put into the heating equipment for heating and melting, thereby completing the production of the floor coating. Since all raw materials are in powder form during the mixing process, there is no need to divide the substrate during the mixing process, and there is no need to overcome the problem of difficulty in dividing due to the high viscosity of the substrate, thereby improving the mixing efficiency. At the same time, since the size of the powder particles is uniform, the uniformity of the mixing is improved, thereby improving the uniformity of the floor coating.

[0024] 2. In the present invention, the side wall of the stirring chamber is set to a medium hole structure, and micro holes are set on the inside. When in use, the cavity inside the stirring chamber can be connected with the external negative pressure generating device through the connecting pipe joint, so that a cavity is formed inside the cavity inside the stirring chamber, which can increase the resistance of the inner side wall of the stirring chamber to the material, thereby avoiding the material from slipping relative to the inner wall, thereby ensuring the relative movement between the stirring rod and the material, thereby ensuring the separation of the substrate by the stirring rod, and thereby ensuring the uniform dispersion of the material; at the same time, when discharging the material, the connecting pipe joint can be transferred to the positive air pressure device to achieve blowing inwards, thereby forming a layer of air mold between the material and the inner wall, thereby preventing the material from sticking, thereby improving the thoroughness of the material discharge, and thereby improving the neatness of the system; at the same time During the stirring process, the air vent can be connected to the external high-pressure (over 3 MPa) air source through the connecting pipe joint, and then the high-pressure airflow is continuously rushed into the inside during the stirring process, so that the high-pressure airflow can cut the raw materials, thereby improving the dispersion uniformity of the raw materials. At the same time, since the raw materials have a certain viscosity, after the airflow enters the mixed raw materials, bubbles will be formed inside the mixed raw materials. Due to the formation of bubbles inside the mixed raw materials, the raw materials have a certain looseness before atomization, and the difficulty of atomization can be reduced during atomization, thereby improving the uniformity of the mixed raw materials after atomization, thereby improving the uniformity of the floor coating. Since the separation needs to be heated and melted later, the bubbles will float up during the heating process to complete the elimination of the bubbles.

[0025] 3. In the present invention, an acceleration section is arranged in the flow channel, and a No. 1 fan is arranged at the acceleration end, so that when the raw material enters the acceleration section in the flow channel, the airflow blown by the No. 1 fan can drive the mist raw material to accelerate, thereby avoiding the subsequent sprayed raw material from mixing with the previously sprayed mixed raw material, thereby avoiding the re-melting of the mist particles, thereby improving the uniformity of the formed powder particles, thereby improving the uniformity of the floor coating; at the same time, because in this scheme, the acceleration section and the receiving section are arranged perpendicular to each other, the movement direction of the mist particles can be changed during acceleration, and the distance between the mist mixed raw materials sprayed in the front and rear time periods is further increased, thereby reducing the probability of collision between the mist raw materials, thereby reducing the probability of melting between the mist mixed raw materials, further ensuring the uniformity of the mist powder particles, further improving the uniformity of the floor coating, and thereby improving the quality of the floor coating.

[0026] 4. In the present invention, a deceleration section is arranged inside the flow channel, and symmetrical airflow parts are arranged above and below the deceleration section, one of the airflow parts blows air and the other airflow part inhales air, thereby forming a flowing air curtain between the two pairs of airflow parts, and the air curtain is arranged obliquely, so that the atomized particles will encounter resistance in the opposite direction of movement when passing through the air curtain, thereby reducing the movement speed of the atomized particles. At the same time, since the air curtain flows with a frozen gas medium, the atomized particles will be quickly frozen and hardened on the surface of the air curtain when passing through it, thereby avoiding the aggregation of particles caused by deceleration and causing sticking. Therefore, it is possible to avoid sticking while ensuring the sphericity, thereby improving the quality of the products produced by the system.

[0027] 5. In the present invention, after freezing, the mist raw material is formed into powder. Because the powder is driven by the airflow, the raw material can enter the electrostatic additional component. After passing through the electrostatic additional component, the powder particles are charged with the same charge, which will cause the powders to repel each other. After entering the mixing bin, the powder is not only driven by the airflow, but also affected by the repulsive force of the charge, thereby increasing the irregularity of the movement of the powder particles, thereby improving the uniformity of mixing, thereby improving the mixing uniformity between the raw materials of the floor coating, and thereby improving the quality of the floor coating; at the same time, by electrically connecting the mobile phone component to the electrostatic generating device, and then aggregating the materials after mixing evenly, the collecting component is charged with a charge opposite to that of the powder particles, which will cause the powder particles to be attracted by the collecting component, and then the powder particles can be quickly gathered on the collecting component, thereby improving the efficiency of collection after mixing, thereby improving the production efficiency of the floor coating.

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 to 9 As shown, a thermoplastic floor coating preparation system comprises a fixing frame 1, a heat stirring component, an atomizing component, a flow channel 2 and an air flotation mixing component; the heat stirring component is arranged on the upper part of one end of the fixing frame 1; the heat stirring component is used to stir and mix the heat-resistant raw materials; the atomizing component is arranged at one end of the heat stirring component, and the atomizing component is connected to the heat stirring component; the flow channel 2 is arranged at one end of the atomizing component; the flow channel 2 is connected to the outlet end of the atomizing component; the flow channel 2 is fixedly connected to the fixing frame 1; a refrigerated gas medium is introduced into the end of the flow channel 2 through a pipeline to freeze the raw materials; the air flotation mixing component is arranged at one end of the flow channel 2 away from the atomizing component; the air flotation mixing component is used to mix the treated heat-resistant raw materials with non-heat-resistant raw materials;

[0041] The atomizing component includes an atomizing pump 3, an atomizing nozzle 4, a connecting piece 5 and an atomizing bin 6; the atomizing pump 3 is arranged on the upper part of the fixing frame 1; the atomizing pump 3 is fixedly connected to the fixing frame 1; the atomizing bin 6 is arranged at one end of the atomizing pump 3; the atomizing bin 6 is fixedly connected to the fixing frame 1; a connecting piece is arranged inside the atomizing bin 6; the connecting piece is fixedly connected to the atomizing bin 6; the atomizing pump 3 is communicated with the connecting piece; the atomizing nozzles 4 are evenly spaced on one side of the connecting piece; the atomizing nozzle 4 is fixedly connected to the connecting piece; the connecting piece is communicated with the atomizing nozzle 4.

[0042] During operation, the composition of floor coatings is relatively complex, and the main components are epoxy resin, phenolic resin and acrylic acid, which can be divided into thermosetting and thermoplastic according to thermal properties. In the production of thermoplastic floor coatings, the materials are relatively viscous at room temperature during the mixing process, which makes it difficult for the stirring rod to separate the matrix material during the mixing process, making it difficult for additives and pigments and other auxiliary materials to be evenly dispersed in the substrate, resulting in quality problems such as floating color in the produced floor coatings, thereby reducing the quality of the floor coatings; in this solution, heat-resistant raw materials such as substrates and pigments are mixed together to form a The material is put into the hot stirring component. Since the hot stirring component has a heating function, the mixed raw materials can be stirred during the stirring process. Since the substrate involved is a thermoplastic substrate, the viscosity of the raw materials can be reduced after the material is heated, making it easier for the raw materials to be separated by the stirring rod, so that the materials can be more evenly dispersed in the substrate. The mixed raw materials are then transported to the atomizing pump 3, the raw materials are pressurized by the atomizing pump 3, and then passed through the atomizing nozzle 4 (an external atomizing nozzle is used, by spraying the raw materials to a certain distance outside the atomizing nozzle 4, and then from A high-pressure airflow is sprayed out from the atomizing nozzle 4, thereby dispersing the mixed raw materials into a mist structure; since the mixed raw materials still have a certain viscosity, the external atomization method is used to make the mixing space larger, thereby reducing the risk of agglomeration after atomization, thereby improving the uniformity of atomization) the raw materials are sprayed out, so that the mixed raw materials form a mist, and then the atomized mixed raw materials enter the flow channel 2. Since the flow channel 2 is filled with cooling gas, the mist mixed material freezes during the process of passing through the flow channel 2, thereby forming powder particles, and then the powder particles enter the air flotation mixing component, and then enter the mixing air flotation component, and then The non-heat-resistant raw material powder in the floor coating is put into the air flotation mixing component, and then the heat-resistant raw material powder and the non-heat-resistant material powder are mixed in the air flotation mixing component. Finally, the mixed raw materials are put into the heating equipment for heating and melting, thereby completing the production of the floor coating. Since all the raw materials are in powder form during the mixing process, there is no need to divide the substrate during the mixing process, and there is no need to overcome the problem of difficulty in dividing due to the high viscosity of the substrate, thereby improving the mixing efficiency. At the same time, since the size of the powder particles is uniform, the mixing uniformity is improved, thereby improving the uniformity of the floor coating.

[0043] like Figures 1 to 8As shown, the hot stirring component includes a stirring chamber 7, a No. 1 motor 8, a connecting pipe joint 9, a hot stirring frame 10 and a valve 11; the No. 1 motor 8 is arranged on the upper part of the stirring chamber 7; the No. 1 motor 8 is fixedly connected to the stirring chamber 7; the hot stirring frame 10 is arranged inside the stirring chamber 7; the hot stirring frame 10 is rotatably connected to the stirring chamber 7; the hot stirring frame 10 is composed of a sheet stirring frame with a heating device inside; the side wall of the stirring chamber 7 is hollow; the inner wall of the stirring chamber 7 is evenly spaced The air vent 12; the diameter of the air vent 12 is 0.2-0.3mm; the connecting pipe joint 9 is provided on the outside of the stirring chamber 7; the connecting pipe joint 9 is fixedly connected to the side wall of the stirring chamber 7; the connecting pipe joint 9 is used to connect the air path device inside and outside the side wall of the stirring chamber 7; the valve 11 is provided at the bottom of the stirring chamber 7; the valve 11 is fixedly connected to the stirring chamber 7; one end of the valve 11 is communicated with the stirring chamber 7; the other end of the valve 11 is connected to the inlet end of the atomizing pump 3.

[0044] During operation, during the stirring process of heat-resistant materials such as substrates, due to the high viscosity of the materials, the materials may adhere to the stirring rod during the stirring process. Compared with the stirring rod, the inner wall of the stirring chamber 7 is often in a smooth state, which will cause the stirring rod to exert a large force on the materials during the stirring process, while the friction resistance of the inner wall to the materials is small, which will cause the materials to slip relative to the inner wall, and the movement of the materials relative to the stirring rod is small, which will reduce the separation of the materials by the stirring rod, resulting in low stirring efficiency and affecting the uniformity of stirring. Therefore, by setting the side wall of the stirring chamber 7 into a mesoporous structure and setting micro holes on the inside, the cavity inside the stirring chamber 7 can be connected to the external negative pressure generating device through the connecting pipe joint 9 during use, so that a cavity is formed in the cavity inside the stirring chamber 7, which can increase the resistance of the inner side wall of the stirring chamber 7 to the materials, thereby avoiding the material from slipping relative to the inner wall, thereby ensuring the relative movement between the stirring rod and the materials, thereby ensuring the separation of the substrate by the stirring rod, and thereby ensuring the uniform dispersion of the materials. At the same time, when discharging, the connecting pipe joint 9 can be used to connect the inner side wall of the stirring chamber 7 to the negative pressure generating device, thereby preventing the material from slipping relative to the inner wall, thereby ensuring the relative movement between the stirring rod and the materials, thereby ensuring the separation of the substrate by the stirring rod, and thereby ensuring the uniform dispersion of the materials. The pipe joint 9 is transferred to the positive air pressure device to blow it inward, so that a layer of air mold can be formed between the material and the inner wall, which can prevent the material from sticking, thereby improving the thoroughness of the material discharge, and thereby improving the neatness of the system; at the same time, during the stirring process, the air vent 12 can be connected to the external high-pressure (more than 3 MPa) air source through the connecting pipe joint 9, and then the high-pressure airflow is continuously rushed into the inside during the stirring process, and then the high-pressure airflow can cut the raw materials, thereby improving the dispersion uniformity of the raw materials. At the same time, because the raw materials have a certain viscosity, after the airflow enters the mixed raw materials, bubbles will be formed inside the mixed raw materials. Since bubbles are generated inside the mixed raw materials, the raw materials have a certain looseness before atomization, and the difficulty of atomization can be reduced during atomization, thereby improving the uniformity of the atomized mixed raw materials, thereby improving the uniformity of the floor coating, and because the separation needs to be heated and melted later (it can be in a negative pressure state during the heating and melting process, thereby accelerating the elimination of bubbles), the bubbles will float up during the heating process to complete the elimination of bubbles.

[0045] like Figures 1 to 8 As shown, the flow channel 2 includes a receiving section 13 and an acceleration section 14; the receiving section 13 is fixedly connected to the atomization bin 6; an acceleration section 14 is arranged on one side of the receiving section 13; the acceleration section 14 is arranged perpendicular to the center line of the receiving section 13; a No. 1 fan 14 is arranged on the upper part of the acceleration section 14; the temperature outlet of the No. 1 fan 14 is connected to the inside of the acceleration section 14.

[0046] During operation, since the mixed raw materials are in a molten state when they are sprayed out, the speed when they are just sprayed out is often relatively fast, and there is a risk of re-melting with the mixed raw materials that are already in an atomized state, thereby forming a mist mixture with larger particles, which will cause uneven particles of the mist mixture, thereby causing uneven production of floor coatings, and thereby reducing the quality of the floor coatings; therefore, in this solution, an acceleration section 14 is provided in the flow channel 2, and a No. 1 fan 14 is provided at the acceleration end, and then when the raw materials enter the acceleration section 14 in the flow channel 2, the airflow blown out by the No. 1 fan 14 can drive the mist raw materials to move faster, thereby preventing the subsequent sprayed raw materials from colliding with the previous ones. The sprayed mixed raw materials are mixed, thereby avoiding the re-melting of the mist particles, thereby improving the uniformity of the formed powder particles, thereby improving the uniformity of the floor coating; at the same time, because in the present scheme, the acceleration section 14 and the receiving section 13 are arranged perpendicular to each other, the movement direction of the mist particles can be changed during acceleration, and the distance between the mist mixed raw materials sprayed in the previous and next time periods is further increased, thereby reducing the probability of collision between the mist raw materials, thereby reducing the probability of welding between the mist mixed raw materials, further ensuring the uniformity of the mist powder particles, further improving the uniformity of the floor coating, and thereby improving the quality of the floor coating.

[0047] like Figures 1 to 8 As shown, the flow channel 2 also includes a deceleration section 16; airflow pieces 17 are evenly spaced on both sides of the deceleration section 16 in the vertical direction; the airflow pieces 17 are arranged in pairs; the connecting line between the paired airflow pieces 17 is arranged obliquely; one of the paired airflow pieces 17 is connected to an external blowing component to realize outward blowing; the other airflow is connected to an external suction device to realize outward suction; the airflow piece 17 blows out a low-temperature gas medium; the temperature of the medium blown out by the airflow piece 17 gradually increases from one end close to the acceleration section 14 to the other end; the temperature of the gas medium does not exceed -5°C.

[0048] During operation, after the mixed raw materials are atomized by the atomizing head, the formed mist particles are in a molten state. Under the action of surface tension, the mist particles tend to be spherical. When the formed mist particles are spherical, the stacking angle of the formed powder will be smaller, and the surface smoothness will increase, thereby increasing the fluidity of the mist particles, and making the powder easier to mix evenly. Therefore, the higher the sphericity of the powder during production, the more positive the effect on the quality of the floor coating. After being accelerated by the acceleration section 14, the atomized particles will move at a high speed, and the resistance encountered during the movement will cause the atomized particles to deform, thereby reducing the sphericity of the atomized particles. Therefore, in this solution, A deceleration section 16 is provided inside the flow channel 2, and symmetrical airflow pieces 17 are provided above and below the deceleration section 16, wherein one of the airflow pieces 17 blows air and the other airflow piece 17 inhales air, thereby forming a flowing air curtain between the two pairs of airflow pieces 17, and the air curtain is provided at an angle, so that the atomized particles encounter resistance in the opposite direction of movement when passing through the air curtain, thereby reducing the movement speed of the atomized particles. At the same time, since the air curtain flows with a frozen gas medium, the atomized particles are quickly frozen and hardened on the surface of the air curtain when passing through it, thereby avoiding the aggregation of particles caused by deceleration and causing sticking. Therefore, it is possible to avoid sticking while ensuring the sphericity, thereby improving the quality of the products produced by the system.

[0049] like Figures 1 to 8 As shown, the air flotation mixing component includes an electrostatic additional component 18, a mixing bin 19, an air pump 20 and a collecting component 21; the outlet end of the flow channel 2 is provided with an electrostatic additional component 18; the electrostatic additional component 18 is used to add static electricity to the powder entering the mixing bin 19; the mixing bin 19 is provided at one end of the flow channel 2; the mixing bin 19 is fixedly connected to the fixed frame 1; the air pump 20 is provided on one side of the mixing bin 19; the air pump 20 is fixedly connected to the mixing bin 19; the outlet end of the air pump 20 is fixedly connected to the upper end of the mixing bin 19; the inlet end of the air pump 20 is connected to the lower end of the mixing bin 19; the inlet end and the outlet end of the air pump 20 are both connected to the inside of the mixing bin 19; the upper part of the mixing bin 19 is provided with a feed port and an air inlet; the lower part of the mixing bin 19 is provided with the collecting component 21; the collecting component 21 is used to collect the mixed materials; the collecting component 21 is electrically connected to an external electrostatic generating device.

[0050] During operation, the mist raw material is formed into powder after being frozen. Because the powder is driven by the airflow, the raw material can enter the electrostatic additional component 18 (it can be a strong electric field, which makes the internal gas medium ionize to form electrons and positive ions. When the powder passes through, the positive ions and the powder are adsorbed to each other, so that the powder has the same charge; or a strong light wave irradiates a thin metal layer, so that the electrons in the metal are freed, so that the powder has the same charge). After passing through the electrostatic additional component 18, the powder particles have the same charge, which will cause the powders to repel each other, and then after entering the mixing chamber 19, The powder is not only driven by the airflow, but also affected by the repulsive force of the electric charge, which increases the irregularity of the movement of the powder particles, thereby improving the uniformity of mixing, thereby improving the uniformity of mixing between the raw materials of the floor coating, thereby improving the quality of the floor coating; at the same time, by electrically connecting the mobile phone component to the electrostatic generating device, and then aggregating the materials after mixing evenly, the collecting component 21 is charged with an opposite charge to the powder particles, which will cause the powder particles to be attracted by the collecting component 21, and then the powder particles can be quickly gathered on the collecting component 21, thereby improving the efficiency of collection after mixing, thereby improving the production efficiency of the floor coating.

[0051] like Figures 1 to 8 As shown, elastic strips 22 are arranged at intervals inside the mixing chamber 19; one end of the elastic strip 22 is fixedly connected to the mixing chamber 19; and the deformation pressure of the elastic strip 22 in the length direction is unevenly distributed.

[0052] During operation, by arranging the elastic strip 22 inside the mixing bin 19, as the air pump 20 blows air into the mixing bin 19, the elastic strip 22 will block the airflow, thereby changing the flow direction of the airflow, thereby increasing the degree of turbulence of the airflow inside the mixing bin 19, thereby increasing the degree of turbulence of the powder mixed inside, thereby improving the uniformity of powder mixing; at the same time, by arranging the deformation pressure of the elastic strip 22 to be unevenly distributed (the thickness of the elastic strip 22 can be set to be different at each position, or a metal elastic sheet can be set inside the elastic strip 22 to make the pressure limit of the deformation of the elastic strip 22 different at each position), when a larger airflow acts on the elastic strip 2 2, some parts will bend and deform, and the degree of bending and deformation is also different, and some parts will not bend and deform, which will increase the path direction of the airflow acting on the elastic strip 22 after the collision, and further increase the degree of turbulence of the airflow inside the mixing chamber 19, thereby improving the mixing uniformity of the powder. At the same time, since the elastic strip 22 is elastic, when airflows of different sizes act at different time periods, the elastic strip 22 presents different shapes, thereby preventing the internal airflow from forming a regular airflow circulation inside the mixing chamber 19, thereby avoiding the occurrence of uneven mixing of the powder, thereby improving the mixing uniformity of the floor coating, and thereby improving the quality of the floor coating.

[0053] like Figures 1 to 8 As shown, a slide groove 23 is provided on the mixing bin 19 ; the collecting member 21 is provided inside the slide groove 23 ; and the collecting member 21 is slidably connected to the slide groove 23 .

[0054] During operation, after the mixing and collection is completed, the powder material needs to be transferred to the heating device for heating. Since the powder is more likely to be disturbed by the airflow during the transfer process, more waste will often be caused during the transfer process, and the dust will cause environmental pollution, which will harm the health of the operator. Therefore, in this solution, the collecting piece 21 is arranged to be connected to the mixing bin 19 in an assembled manner, and the dust material is collected by electrostatic adsorption. After the dust collection is completed, a relatively stable state will be formed between the collecting piece 21 and the dust. Therefore, the collecting piece 21 is directly taken out and directly transferred to the heating equipment for heating. The dust will be in a relatively stable state during the transfer process, which can reduce the loss of dust and reduce the pollution of dust to the environment.

[0055] like Figures 1 to 8 As shown, the cross section of the hot stirring rack 10 is elliptical; the outer surface of the hot stirring rack 10 is provided with an anti-stick coating 24 at both ends of the long axis of the ellipse; the span of the anti-stick coating 24 does not exceed 1 / 2 of the circumference of the ellipse.

[0056] During operation, since the hot stirring rack 10 needs to heat the mixed material during the stirring process, it also needs to cut the mixed material. When cutting, the smaller the contact area between the cutting surface and the material, the smaller the resistance during cutting, and thus the higher the cutting efficiency. When heating, the larger the contact area between the stirring rack and the mixed material, the better, so that the heating efficiency can be improved. Therefore, in this solution, the cross section of the hot stirring rack 10 is set to an elliptical shape, so that the cutting surface can be reduced while ensuring that the contact area between the stirring rack and the material is large, thereby improving the cutting efficiency. At the same time, an anti-stick coating 24 (such as a Teflon coating) is set at the position of the cutting surface of the hot stirring rack 10. Since the adhesion between the coating and the material is low, the resistance during cutting of the material can be reduced, thereby improving the stirring efficiency. At the same time, the span of the coating is controlled, so that the adhesion resistance between the non-cutting surface and the material support can be maintained when the stirring rack cuts the material, so that a driving force is generated on the passing material during the cutting process, so that the flow of the raw materials can be accelerated during the cutting process, thereby achieving a better mixing effect, thereby improving the uniformity and efficiency of the mixing.

[0057] During operation, heat-resistant raw materials such as substrates and pigments are put into the hot stirring component. Since the hot stirring component has a heating function, the mixed raw materials can be stirred during the stirring process. Since the substrate involved is a thermoplastic substrate, the viscosity of the raw materials can be reduced after the materials are heated, making it easier for the raw materials to be separated by the stirring rod, so that the materials can be more evenly dispersed in the substrate. The mixed raw materials are then transported to the atomizing pump 3, the raw materials are pressurized by the atomizing pump 3, and then the raw materials are passed through the atomizing nozzle 4 (an external atomizing nozzle is used, which is used to pressurize the raw materials by the atomizing nozzle 4). The raw materials are sprayed to a certain distance outside the atomizing nozzle 4, and then a high-pressure airflow is sprayed from the atomizing nozzle 4 to disperse the mixed raw materials into a mist structure; since the mixed raw materials still have a certain viscosity, the external atomization method is used to make the mixing space larger, thereby reducing the risk of agglomeration after atomization, thereby improving the uniformity of atomization) The raw materials are sprayed to form a mist of the mixed raw materials, and then the atomized mixed raw materials enter the flow channel 2. Since the flow channel 2 is filled with cooling gas, the mist of the mixed material is frozen during the process of passing through the flow channel 2, thereby forming powder particles, and then the powder particles enter the air flotation mixing group In the mixing component, the non-heat-resistant raw material powder in the floor coating is put into the air flotation mixing component, and then the heat-resistant raw material powder and the non-heat-resistant material powder are mixed in the air flotation mixing component. Finally, the mixed raw materials are put into the heating equipment for heating and melting, thereby completing the production of the floor coating. Since all the raw materials are in powder form during the mixing process, there is no need to divide the substrate during the mixing process, and there is no need to overcome the problem of difficulty in dividing due to the high viscosity of the substrate, thereby improving the mixing efficiency. At the same time, since the size of the powder particles is uniform, the mixing efficiency is improved. uniformity, thereby improving the uniformity of the floor coating; in the process of stirring heat-resistant materials such as substrates, due to the high viscosity of the materials, the materials will adhere to the stirring rod during the stirring process, and the inner wall of the stirring chamber 7 is often smooth relative to the stirring rod, which will cause the stirring rod to exert a greater force on the material during the stirring process, while the friction resistance of the inner wall to the material is smaller, which will cause the material to slip relative to the inner wall, and the movement of the material relative to the stirring rod is smaller, which will cause the stirring rod to reduce the separation of the material, resulting in lower stirring efficiency and affecting the uniformity of stirring;Therefore, by setting the side wall of the stirring chamber 7 to a medium hole structure and setting micro holes on the inside, the cavity inside the stirring chamber 7 can be connected to the external negative pressure generating device through the connecting pipe joint 9 during use, so that a cavity is formed inside the cavity inside the stirring chamber 7, thereby increasing the resistance of the internal side wall of the stirring chamber 7 to the material, thereby avoiding the material from slipping relative to the inner wall, thereby ensuring the relative movement between the stirring rod and the material, thereby ensuring the separation of the substrate by the stirring rod, and thereby ensuring the uniform dispersion of the material; at the same time, when discharging the material, it is possible to achieve blowing inward by transferring the connecting pipe joint 9 to the positive air pressure device, thereby forming a layer of air mold between the material and the inner wall, thereby preventing the material from sticking, thereby improving the thoroughness of the material discharge, and thereby improving the neatness of the system; at the same time, during the stirring process, the connecting pipe joint 9 can be connected The pipe joint 9 connects the air hole 12 with an external high-pressure (more than 3 MPa) air source, and then continuously rushes into the interior during the stirring process, so that the high-pressure airflow can cut the raw materials, thereby improving the dispersion uniformity of the raw materials. At the same time, since the raw materials have a certain viscosity, after the airflow enters the mixed raw materials, bubbles will be formed inside the mixed raw materials. Since bubbles are generated inside the mixed raw materials, the raw materials have a certain looseness before atomization, and the difficulty of atomization can be reduced during atomization, thereby improving the uniformity of the atomized mixed raw materials, thereby improving the uniformity of the floor coating. Since the separation needs to be heated and melted later (it can be in a negative pressure state during the heating and melting process, thereby accelerating the elimination of bubbles), the bubbles will float up during the heating process to complete the elimination of bubbles. ;
