Description

Technical Field

[0001] The present application belongs to the technical field of waterproof coating processing, and in particular relates to a polyurethane waterproof coating production device and a method for using the same. Background Art

[0002] Polyurethane waterproof coating is a single-component polyurethane waterproof coating made from an isocyanate-containing prepolymer formed by the addition polymerization reaction of isocyanate, polyether, etc., combined with a catalyst, anhydrous additives, anhydrous fillers, solvents, etc., and processed through mixing and other processes.

[0003] This type of coating is a reaction-curing (moisture-curing) coating characterized by high strength, high elongation, and excellent water resistance. It is highly adaptable to substrate deformation. Polyurethane waterproof coating is a liquid-applied, one-component, environmentally friendly waterproof coating based on imported polyurethane prepolymers, free of additives such as tar and asphalt. It cures upon contact with moisture in the air, forming a strong, tough, seamless, integral waterproof membrane on the substrate surface.

[0004] Powder is a crucial additive in the production of waterproof coatings. It must be kept dry and contain a moderate amount of moisture during storage, but existing powder storage systems present numerous challenges. For example, patent publication number CN108517179B discloses a polyurethane waterproof coating production process, which includes the following steps: weighing a certain amount of coating raw material using a metering device; temporarily storing the weighed coating raw material in a coating storage device; transferring the coating from the coating storage device to a mixing device for mixing; pumping the mixed coating to a filling device; the filling device then fills the coating into a coating bucket; and capping the filled coating bucket with a capping device.

[0005] The above patent drives the storage box to tilt through the second motor, and cooperates with the propulsion mechanism to quickly push out the powder in the storage box, thereby realizing the rapid addition of different powders. However, in order to completely discharge the powder, the propulsion mechanism cooperates very tightly with the storage box, so that severe friction will be generated during the pushing process. Long-term use will cause the pushing function to fail, and the push plate will easily squeeze the powder that has not been completely pushed backwards when resetting. Over time, it will cause the powder to accumulate, affecting the subsequent pushing of the powder. Summary of the Invention

[0006] The purpose of this application is to provide a polyurethane waterproof coating production equipment and its use method, which can solve the above problems.

[0007] The purpose of this application is to provide a polyurethane waterproof coating production equipment, including:

[0008] A storage tank body, wherein the storage tank body is used to store powder;

[0009] Reactor;

[0010] A conveying device, which is used to convey the powder in the storage tank to the reactor;

[0011] A heating mechanism, which is used to heat and dry the powder;

[0012] The storage tank body is further provided with a plurality of storage mechanisms spaced apart in an upper and lower direction. The storage mechanism includes a storage box, an angle adjustment structure provided on the storage box, and a powder pushing structure.

[0013] By adopting the above-mentioned polyurethane waterproof coating production equipment, powder can be stored by setting up a storage tank body. Multiple storage mechanisms arranged at intervals are set in the storage tank body, which can store multiple powders, thereby improving practicality. Multiple powders can also be stored separately to prevent the powders from getting damp. At the same time, by setting up a heating mechanism, the powder can be dried by the heating mechanism to further prevent the powders from getting damp. By setting up a conveying mechanism and with the cooperation of the angle adjustment structure and the powder pushing structure, the powder on the storage box can be quickly conveyed to the reactor. Among them, the setting of the powder pushing structure can effectively prevent the powder from remaining on the conveying box, thereby improving the utilization efficiency of the powder and saving resources.

[0014] Furthermore, the storage structure also includes a receiving hopper, one end of which is located in the storage tank body and the other end extends outside the storage tank body. The end of the receiving hopper located in the storage tank body is used to receive the powder discharged from the storage box, and the other end of the receiving hopper is connected to the conveying device, and the powder is conveyed to the reactor through the conveying device.

[0015] The setting of the receiving hopper can accurately deliver the powder in the storage box into the conveying device, and can also play a limiting role. When the angle adjustment device drives the storage box to adjust the angle, when it is adjusted to a certain angle, the receiving hopper will block the storage box to prevent the storage box from rotating excessively.

[0016] Furthermore: the angle adjustment structure includes a positioning rod and a plurality of drive motors arranged on the positioning rod, the plurality of drive motors are distributed at intervals up and down along the positioning rod, and each drive motor corresponds to the position of the storage box and is connected to the storage box.

[0017] After the driving motor is started, the angle of the storage box can be adjusted to make the storage box deflect, and the powder can be more easily exported through the tilt angle and the influence of gravity. At the same time, each driving motor can operate independently and is not connected to each other. Among them, by setting a positioning rod, multiple motors are installed on the positioning rod, which can facilitate the disassembly and installation of the motor and the storage box, and will not affect the storage tank body during disassembly and installation.

[0018] Furthermore, the powder pushing structure includes:

[0019] Slide slots are provided on both sides of the storage box;

[0020] A damping member is provided in each chute;

[0021] A push plate is disposed in the storage box;

[0022] a connecting member, one end of which is connected to the push plate, and the other end of which is connected to the damping member;

[0023] cylinder;

[0024] Among them, each connecting member consists of a first vertical plate, a second vertical plate and a horizontal plate, wherein the first vertical plate is connected to the push plate, the second vertical plate is connected to the damping member, the two ends of the horizontal plate are respectively connected to the first vertical plate and the second vertical plate, and the cylinder is connected to the second vertical plate.

[0025] When the cylinder pushes the second vertical plate to move, the push plate moves accordingly. The movement of the push plate will drive the damping member to move together through the connecting member. One end of the damping member here is a retractable structure. When the push plate moves, the expansion and contraction of the damping member generates a damping force, which can make the movement of the push plate more stable and reduce the resistance received during movement, thereby reducing friction, reducing the wear of the push plate, and extending the service life of the push plate. At the same time, the connecting member is composed of a first vertical plate, a horizontal plate and a second vertical plate, which can extend the effective distance of the components, thereby making the cooperation between the push plate and the damping member more stable.

[0026] Furthermore, an elastic member is provided in the slide groove, one end of the elastic member is connected to the second vertical plate, and the other end is installed on the inner wall of the slide groove.

[0027] By setting an elastic member, which is a compression spring, when the push plate moves, the second vertical plate will also move, which can cause the compression spring to be stretched or compressed, thereby achieving a damping and buffering effect. The use of the elastic member and the damping member in combination can further increase the damping force, making the push plate more stable when moving and pushing.

[0028] Furthermore, the powder pushing structure further includes:

[0029] A mounting groove is provided in the side wall of the storage box, and the first vertical plate is installed in the mounting groove;

[0030] An annular movable groove is provided on the inner wall of the storage box, and a first protrusion that cooperates with the annular movable groove is provided on the side wall of the push plate;

[0031] A horizontal movement groove is provided on the inner wall of the mounting groove and is connected to the annular movement groove. The first vertical plate is provided with a second protrusion that cooperates with the horizontal movement groove;

[0032] a connecting rod, one end of which is hinged to the first protrusion, and the other end of which is hinged to the second protrusion;

[0033] Among them, the annular moving groove is an elliptical structure.

[0034] In the process of pushing the powder material, in order to prevent the push plate from pushing the remaining powder material back, thereby preventing the powder material from being transported away and agglomerating due to long-term accumulation, thus affecting subsequent use, the present application is provided with an annular moving groove. When the cylinder pushes the second vertical plate to move, the second vertical plate drives the first vertical plate to move through the horizontal plate, and the first vertical plate drives the first protrusion to move through the second protrusion and the connecting rod, thereby moving the push plate. Since the first protrusion is located in the horizontal moving groove and the second protrusion is located in the annular moving groove, during the initial movement process, the first protrusion is affected by the horizontal moving groove. The block and the second protrusion both keep moving horizontally. When the first protrusion moves to the horizontal limit position of the annular moving groove, the push block also moves to the limit distance, and then the push block will retreat. At this time, affected by the structure of the annular moving groove, the first protrusion will make an annular motion along the annular moving groove. At this time, the push block is lifted up by the influence of the first protrusion, and then the push block cannot contact the bottom surface of the storage box, thereby preventing the push block from pushing the remaining powder back. After the push block is reset, affected by the annular structure of the annular moving groove, the push plate will contact the bottom surface of the storage box again to carry out the next pushing work.

[0035] Furthermore, the conveying device includes a plurality of interconnected pipes and a telescopic tube cooperating with the receiving hopper, a plurality of first cooperating openings are provided on the outside of the storage tank body, and a second cooperating opening cooperating with the first cooperating opening is provided on the telescopic tube.

[0036] By setting up a telescopic tube, the transportation of different powders can be achieved by extending and retracting the telescopic tube. The extension and retraction of the telescopic tube can make the first matching port on the telescopic tube match with different second matching ports, thereby transporting powders in different storage boxes to the reactor.

[0037] Furthermore, the present invention also discloses a method for using a polyurethane waterproof coating production device, comprising the following steps:

[0038] S1. Storing different powders in multiple storage boxes;

[0039] S2. Using the angle adjustment structure to adjust the angle of the storage box;

[0040] S3, the telescopic tube is connected to the first matching port corresponding to the side of the powder to be added through the second matching port;

[0041] S4. The powder in the overturned storage box is fed into the telescopic tube through the receiving hopper, and the powder enters the reactor through the telescopic tube and the pipeline.

[0042] The beneficial effects of this application are:

[0043] 1. By arranging multiple storage mechanisms at intervals in the storage tank body, a variety of powders can be stored, which improves practicality. The various powders can also be stored separately to prevent the powders from getting damp. By arranging a heating mechanism, the powders can be dried by the heating mechanism to further prevent the powders from getting damp. By arranging a conveying mechanism, and with the cooperation of the angle adjustment structure and the powder pushing structure, the powder on the storage box can be quickly conveyed to the reactor. The setting of the powder pushing structure can effectively prevent the powder from remaining on the conveying box, thereby improving the utilization efficiency of the powder and saving resources.

[0044] 2. When the push plate moves, the expansion and contraction of the damping element generates a damping force, which can make the movement of the push plate more stable and reduce the resistance received during movement, thereby reducing friction, reducing the wear of the push plate, and extending the service life of the push plate. At the same time, the connecting member consists of a first vertical plate, a horizontal plate, and a second vertical plate, which can extend the effective distance of the assembly, thereby making the cooperation between the push plate and the damping element more stable;

[0045] 3. By providing an annular movable groove, when the cylinder pushes the first vertical plate to move, affected by the horizontal movable groove, the first protrusion and the second protrusion both maintain horizontal movement. When the first protrusion moves to the horizontal limit position of the annular movable groove, the push block then retreats. Affected by the structure of the annular movable groove, the first protrusion will make an annular motion along the annular movable groove, and the push block will be lifted up by the influence of the first protrusion, thereby preventing the push block from contacting the bottom surface of the storage box, thereby preventing the push block from pushing the remaining powder back. After the push block is reset, affected by the annular structure of the annular movable groove, the push plate will contact the bottom surface of the storage box again to carry out the next pushing work.

In addition to the above-mentioned technical features, the polyurethane waterproof coating production device of the embodiment of the present application also includes the following technical features.

[0072] like Figures 2 to 4 As shown, the powder pushing structure 400 includes:

[0073] Slide grooves 410 are provided on both sides of the storage box 140;

[0074] A damping member 420 is provided in each chute 410;

[0075] The push plate 430 is disposed in the storage box 140;

[0076] A connecting member 440 , one end of which is connected to the push plate 430 , and the other end of which is connected to the damping member 420 ;

[0077] Cylinder 450;

[0078] Among them, each connecting member 440 is composed of a first vertical plate 441, a second vertical plate 442 and a horizontal plate 443, wherein the first vertical plate 441 is connected to the push plate 430, the second vertical plate 442 is connected to the damping member 420, the two ends of the horizontal plate 443 are respectively connected to the first vertical plate 441 and the second vertical plate 442, and the cylinder 450 is connected to the second vertical plate 442.

The movement of the push plate 430 will drive the damping member 420 to move together through the connecting member 440. One end of the damping member 420 here is a retractable structure. When the push plate 430 moves, the expansion and contraction of the damping member 420 generates a damping force, which can make the movement of the push plate 430 more stable, and can also reduce the resistance received during movement, thereby reducing friction, reducing the wear of the push plate 430, and extending the service life of the push plate 430. At the same time, the connecting member 440 is composed of a first vertical plate 441, a horizontal plate 443 and a second vertical plate 442, which can extend the effective distance of the components, thereby making the cooperation between the push plate 430 and the damping member 420 more stable.

[0082] Example 5:

[0083] An embodiment of the present application provides a polyurethane waterproof coating production device. In addition to the above-mentioned technical features, the polyurethane waterproof coating production device of the embodiment of the present application also includes the following technical features.

[0084] like Figures 2 to 4 As shown, the powder pushing structure 400 further includes:

[0085] The mounting groove 500 is provided in the side wall of the storage box 140 , and the first vertical plate 441 is installed in the mounting groove 500 ;

[0086] An annular movable groove 510 is provided on the inner wall of the storage box 140 , and a first protrusion 511 that cooperates with the annular movable groove 510 is provided on the side wall of the push plate 430 ;

[0087] The horizontal movement groove 520 is provided on the inner wall of the mounting groove 500 and is connected to the annular movement groove 510. The first vertical plate 441 is provided with a second protrusion 521 that cooperates with the horizontal movement groove 520.

Since the first protrusion 511 is located in the horizontal movable groove 520 and the second protrusion 521 is located in the annular movable groove 510, during the initial movement, the horizontal protrusion 521 is located in the annular movable groove 510. Under the influence of the movable groove 520, the first protrusion 511 and the second protrusion 521 both maintain horizontal movement. When the first protrusion 511 moves to the horizontal limit position of the annular movable groove 510, the push block also moves to the limit distance, and then the push block will retreat. At this time, affected by the structure of the annular movable groove 510, the first protrusion 511 will make a circular motion along the annular movable groove 510. At this time, the push block is lifted up by the influence of the first protrusion 511, and the push block cannot contact the bottom surface of the storage box 140, thereby preventing the push block from pushing the remaining powder back. After the push block is reset, affected by the annular structure of the annular movable groove 510, the push plate 430 will contact the bottom surface of the storage box 140 again to carry out the next pushing work.
