[0015] The beneficial effects of the present invention are as follows: the waterborne polyurethane coating mixing and filling equipment described in the present invention efficiently transports the raw materials to the inside of the box through the feed pipe, and then starts the stirring mechanism to stir the raw materials entering the box comprehensively and evenly, ensuring that each raw material can be fully mixed. During this stirring process, the stamping mechanism starts and starts working synchronously, gradually increasing the pressure in the box. This increase in pressure can make the colorant and the waterborne polyurethane coating more fully mixed during the stirring process, thereby improving the uniformity of the mixing, and can also discharge the mixed raw materials from the box at a faster rate, greatly improving the production efficiency. In addition, in order to keep the inside of the box clean and prevent the raw materials from adhering to the inner wall during the stirring process, the cleaning mechanism is cleverly designed to work synchronously with the stirring mechanism. While stirring is in progress, the cleaning mechanism, with its unique scraping wall design, gently scrapes off the raw materials attached to the inner wall of the box, ensuring that the inside of the box is always kept clean.

[0016] The water-based polyurethane coating mixing and filling equipment described in the present invention starts the motor, so that the motor drives the rotating tube to rotate and the stirring tube to rotate, thereby stirring the raw materials and making the raw materials fully mixed. When the motor is started, it drives the first belt transmission assembly connected thereto to start running. The rotation of the first belt transmission assembly cleverly drives the first reciprocating screw to start rotating. This precise design enables the entire system to work in coordination. With the rotation of the first reciprocating screw, the connecting ring will start to move up and down along the screw. When the connecting ring moves up and down, the fixed plate also moves synchronously. Below the fixed plate is an elastic airbag. This ingeniously designed component begins to gradually shrink under the pressure of the fixed plate, squeezing out the gas stored inside it. These squeezed gases are efficiently transported to the inside of the box through the first air inlet pipe, thereby pressurizing the box, which can speed up the efficiency of subsequent filling. The first one-way valve can effectively prevent the gas from flowing back during the pressurization process, thereby ensuring the continuity and stability of the pressurization. At the same time, in order to limit the moving trajectory of the fixed plate and ensure that it can move according to the predetermined path, a limit tube is also set up in the system. Finally, the air pressure in the box can be detected by the air pressure detector in the box, and then transmitted to the control panel. When the air pressure is too high, the air release valve is opened to release air to avoid damage to the equipment due to excessive air pressure in the box.

[0017] The water-based polyurethane coating mixing and filling equipment described in the present invention, when the motor is activated and started, drives the second belt drive assembly (the belt drive assembly includes two pulleys and a belt) to rotate, and the second reciprocating screw connected thereto is also driven, so that the sliding ring moves up and down outside the second reciprocating screw, and when the sliding ring moves up and down, the cleaning plate will also move synchronously. The cleaning plate is close to the inner wall of the box body, and through its up and down reciprocating movement, the inner wall of the box body is effectively and thoroughly cleaned to ensure that no residue is attached. The traction ring is designed to move outside the traction tube, ensuring its smooth movement during the cleaning process, and will not deviate from the predetermined cleaning path due to external interference. In addition, considering that the raw material may flow into the installation groove, when the traction ring and the sliding ring move downward, the first telescopic protective cover will extend, and the second telescopic protective cover will telescope, thereby ensuring that no raw material will flow into the installation groove when the traction ring and the sliding ring move.

DETAILED DESCRIPTION

It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0021] Embodiment 1 like Figures 1 to 6 As shown, a water-based polyurethane coating mixing and filling device according to an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3, including a filling box 100, the filling box 100 includes a box body 101, the upper end of the box body 101 is fixedly connected with a stirring mechanism 200, the interior of the box body 101 is provided with a cleaning mechanism 800, the lower end of the box body 101 is fixedly connected with a conical frame 500, the lower end of the conical frame 500 is fixedly connected with a discharging mechanism 400, the stirring mechanism 200 includes a box cover 201 fixedly connected to the upper end of the box body 101, the upper end of the box cover 201 is fixedly connected with a feeding pipe 207, the upper end of the box cover 201 is fixedly connected with a motor 202, the output end of the motor 202 is sleeved with a first belt transmission assembly 203, and the other side of the first belt transmission assembly 203 is provided with a stamping mechanism 300.

[0022] Specifically, the raw materials are efficiently transported to the inside of the box 101 through the feed pipe 207, and then the stirring mechanism 200 is started to stir the raw materials entering the box 101 comprehensively and evenly to ensure that each raw material can be fully mixed. During this stirring process, the punching mechanism 300 is synchronously started and starts to work, gradually increasing the pressure in the box 101. This increase in pressure can make the colorant and the water-based polyurethane coating more fully mixed during the stirring process, thereby improving the uniformity of the mixing, and can also discharge the mixed raw materials from the box 101 at a faster rate, greatly improving the production efficiency. In order to keep the inside of the box 101 clean and prevent the raw materials from adhering to the inner wall during the stirring process, the cleaning mechanism 800 is cleverly designed to work synchronously with the stirring mechanism 200. While stirring, the cleaning mechanism 800, with its unique wall scraping design, gently scrapes off the raw materials adhering to the inner wall of the box 101, ensuring that the inside of the box 101 is always kept clean.

[0023] Please refer to Figure 3The punching mechanism 300 includes a first reciprocating screw rod 301 sleeved on the first belt transmission assembly 203, the outer side of the first reciprocating screw rod 301 is threadedly connected with a connecting ring 302, and the outer side of the connecting ring 302 is fixedly connected with a fixing plate 305. The punching mechanism 300 also includes a mounting plate 303 fixedly connected to the box body 101 on the same side as the first reciprocating screw rod 301, the upper end of the mounting plate 303 is fixedly connected with an elastic airbag 304, the upper end of the mounting plate 303 is fixedly connected with a limiting tube 306 that penetrates the fixing plate 305, the limiting tube 306 is slidably connected to the fixing plate 305, and the elastic airbag 304 is fixedly connected to the side facing the box body 101 A first air inlet pipe 307, the other end of the first air inlet pipe 307 is fixedly connected to the box body 101, a first non-return valve 308 is sleeved on the outer side of the first air inlet pipe 307, a second air inlet pipe 309 is fixedly connected to the other side of the elastic airbag 304, a second non-return valve 310 is sleeved on the outer side of the second air inlet pipe 309, the output end of the motor 202 passes through the box cover 201 and is fixedly connected to the rotating tube 204, the box cover 201 is rotatably connected to the output end of the motor 202, a plurality of stirring tubes 205 are fixedly connected to the outer side of the rotating tube 204, a bleed valve 206 is fixedly connected to the upper end of the box cover 201, and a solenoid valve 208 is sleeved on the outer side of the feed pipe 207.

[0024] Specifically, by starting the motor 202, the motor 202 drives the rotating tube 204 to rotate, and the stirring tube 205 to rotate, so as to stir the raw materials and make the raw materials fully mixed. When the motor 202 is started, it drives the first belt transmission assembly 203 connected thereto to start running. The rotation of the first belt transmission assembly 203 cleverly drives the first reciprocating screw 301 to start rotating. This sophisticated design enables the entire system to work in coordination. As the first reciprocating screw 301 rotates, it drives the connecting ring 302 to start moving up and down along the screw. When the connecting ring 302 moves up and down, the fixed plate 305 also moves synchronously. Below the fixed plate 305 is the elastic airbag 304. This ingeniously designed component begins to gradually shrink under the pressure of the fixed plate 305, squeezing out the gas stored inside it. These squeezed gases are efficiently transported to the interior of the box 101 through the first air inlet pipe 307, thereby pressurizing the box 101, which can speed up the efficiency of subsequent canning. The first one-way valve 308 can effectively prevent the gas from flowing back during the pressurization process, thereby ensuring the continuity and stability of the pressurization. At the same time, in order to limit the movement trajectory of the fixed plate 305 and ensure that it can move according to the predetermined path, a limit tube 306 is also set in the system. Finally, the air pressure in the box 101 can be detected by the air pressure detector in the box 101, and then transmitted to the control panel 700. When the air pressure is too high, the air release valve 206 is opened to release the air to avoid excessive air pressure in the box 101 damaging the equipment.

[0025] Please refer to Figure 4 , Figure 6 The box body 101 is provided with four mounting grooves 102, and a mounting hole 103 is provided on one side of the box body 101. The cleaning mechanism 800 includes a second belt transmission assembly 801 sleeved on the output end of the motor 202, and the other side of the second belt transmission assembly 801 is sleeved on the outer side of the second reciprocating screw rod 802, and the second reciprocating screw rod 802 is rotatably connected to the inside of one of the mounting grooves 102, and the outer side of the second reciprocating screw rod 802 is threadedly connected with a sliding ring 803, and one side of the sliding ring 803 is fixedly connected with a cleaning plate 804, and the other three corners of the cleaning plate 804 are fixedly connected with traction rings 808, and the traction ring 808 is sleeved on the outer side of the traction tube 807, and the traction tube 807 is fixedly connected to the inside of the other three mounting grooves 102, and the upper ends of the sliding ring 803 and the traction ring 808 are fixedly connected with a first telescopic protective cover 805, and the lower ends of the sliding ring 803 and the traction ring 808 are fixedly connected with a second telescopic protective cover 806.

[0026] Specifically, when the motor 202 is activated and started, it drives the second belt drive assembly 801 (the belt drive assembly includes two pulleys and a belt) to rotate, and the second reciprocating screw rod 802 connected thereto is also driven, causing the sliding ring 803 to move up and down outside the second reciprocating screw rod 802. When the sliding ring 803 moves up and down, the cleaning plate 804 will also move synchronously therewith. The cleaning plate 804 is close to the inner wall of the box body 101, and through its up and down reciprocating movement, it effectively and thoroughly cleans the inner wall of the box body 101 to ensure that there is no residue attached. The traction ring 808 is designed to move on the outside of the traction tube 807, ensuring its smooth movement during the cleaning process and will not deviate from the predetermined cleaning path due to external interference. In addition, considering that the raw materials may flow into the installation groove 102, when the traction ring 808 and the sliding ring 803 move downward, the first telescopic protective cover 805 will extend and the second telescopic protective cover 806 will retract, thereby ensuring that no raw materials will flow into the installation groove 102 when the traction ring 808 and the sliding ring 803 move.

[0027] Please refer to Figure 5 A control panel 700 is fixedly connected to the outer side of the box body 101, and the control panel 700 is electrically connected to the motor 202. A plurality of supporting legs 600 are fixedly connected to the lower end of the box body 101. A discharge box 401 is fixedly connected to the lower end of the conical frame 500. A sliding groove 402 is provided on one side of the discharge box 401. A baffle 403 is slidably connected inside the sliding groove 402. A pull groove 404 is provided on one side of the baffle 403 located on the outer side of the sliding groove 402.

[0028] Specifically, through the control panel 700, the operator can easily realize the start control of the motor 202. When the raw materials are fully mixed in the box body 101 for a predetermined time, they enter the preparation stage of filling. At this time, the operator pulls the pull groove 404, and the baffle 403 can quickly and smoothly disengage from the sliding groove 402, so as to carry out filling, which fully reflects the humanization and efficiency of the equipment and brings great convenience and benefits to production.

[0029] How it works In the initial state, the raw materials are efficiently transported to the interior of the box 101 through the feed pipe 207. Subsequently, the motor 202 is started, so that the motor 202 drives the rotating tube 204 to rotate, and the stirring tube 205 to rotate, so as to stir the raw materials and make the raw materials fully mixed. When the motor 202 is started, it drives the first belt transmission assembly 203 connected thereto to start running. The rotation of the first belt transmission assembly 203 cleverly drives the first reciprocating screw 301 to start rotating, which will drive the connecting ring 302 to start moving up and down along the screw. When the connecting ring 302 moves up and down, the fixed plate 305 also moves synchronously. Below the fixed plate 305 is the elastic airbag 304. This ingeniously designed component begins to gradually shrink under the pressure of the fixed plate 305, squeezing out the gas stored inside it. These squeezed gases are efficiently transported to the interior of the box 101 through the first air inlet pipe 307, thereby pressurizing the box 101. The first one-way valve 308 can effectively prevent the gas from flowing back during the pressurization process, thereby ensuring the continuity and stability of the pressurization. The gas is transported to the elastic airbag 304 through the second air inlet pipe 309, and the second one-way valve 310 allows the gas to be transported to the elastic airbag 304 only from the second air inlet pipe 309. When the motor 202 is activated and started, it drives the second belt drive assembly 801 to rotate, and the second reciprocating screw 802 connected thereto is also driven, causing the sliding ring 803 to move up and down on the outside of the second reciprocating screw 802. When the sliding ring 803 moves up and down, the cleaning plate 804 will also move synchronously. The cleaning plate 804 is in close contact with the inner wall of the box body 101, and through its up and down reciprocating movement, it effectively and thoroughly cleans the inner wall of the box body 101 to ensure that there is no residue attached. When the raw materials are fully mixed in the box body 101 for a predetermined time, it enters the preparation stage for filling. At this time, the operator pulls the pull groove 404, and the baffle 403 can be quickly and smoothly separated from the sliding groove 402, so as to carry out filling.

[0030] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
