AI Technical Summary
In existing mixing equipment, the temperature inside the mixing tank rises due to frictional contact between the mixing shaft and the raw materials during the mixing process, requiring static cooling, which in turn affects production efficiency.
The design employs guide components and protrusions combined with an extrusion bladder, along with an annular bladder and a disc structure. Through the rotation of the guide components and the extrusion of the protrusions, the raw materials are fully mixed, and the alternating action of the film and gas is used to prevent temperature rise.
This ensures that the temperature inside the mixing tank does not rise during the mixing process, thus guaranteeing the stability of the raw materials and the mixing effect, and improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating preparation technology, specifically to a low-temperature spraying material preparation device. Background Technology
[0002] Spray paint is an amorphous material applied using pneumatic tools and mechanical spraying. Depending on the application, the mixing ratio of spray paint varies. In the production process, different raw materials need to be mixed to prepare the spray paint. Low-temperature spray paint is also a common type of spray paint, which is used for curing in low-temperature environments, such as the curing of low-temperature curing resin coatings in low-temperature environments.
[0003] When using common mixing equipment, the temperature inside the mixing tank will rise due to the frictional contact between the mixing shaft and the raw materials. In order to ensure the mixing effect of the resin raw materials, the temperature of the mixing tank needs to be kept constant during the mixing process. Therefore, it needs to be allowed to stand and cool after mixing for a period of time, which leads to a decrease in production efficiency. In view of this, we propose a low-temperature spraying material preparation equipment. Utility Model Content

In order to ensure the mixing effect of the resin raw material, the temperature of the mixing tank needs to be kept constant during the mixing process.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] The present invention will be further described below with reference to the embodiments.
[0032] Example: Refer to Appendix Figure 1-4As shown, a low-temperature spray coating material preparation device includes a mixing tank 100, a cover 200 on the upper side of the mixing tank 100, and a feed hole 201 located in the middle of the cover 200. Various raw materials are poured into the mixing tank 100 through the feed hole 201 and stirred in the mixing chamber 101 opened in the mixing tank 100. The device also includes a discharge port opened in the middle of the lower side of the mixing tank 100. It should be noted that the discharge port is equipped with a sealing plate, which is removable. After stirring is completed, the corresponding discharge port will open to remove the coating material from the mixing chamber 101.
[0033] In this application, to avoid the temperature rise caused by the stirring shaft in a common mixing tank 100 when mixing various raw materials, this application includes a rotating shaft 300 inserted inside the mixing tank 100. The rotating shaft 300 is fixedly connected to the output end of an external motor. A guide member 310 is fixedly installed at the lower end of the rotating shaft 300. Multiple strip-shaped grooves 311 are evenly distributed through the guide member 310, and a thin film (an elastic film) is disposed within each strip-shaped groove 311. A discharge hole 312 is also provided at the edge of the guide member 310. During mixing, the external motor is running, thereby driving the rotating shaft 300 to rotate. The rotating shaft 300 and... The guide members 310 are fixedly connected, and the guide members 310 will also rotate synchronously. It should be noted that when multiple raw materials are poured into the mixing tank 100 through the feed hole 201, the raw materials will be on the upper surface of the guide members 310. As the guide members 310 rotate, multiple raw materials will move along the strip groove 311 toward the inner wall of the mixing chamber 101. When the rotating shaft 300 rotates, the film located in the strip groove 311 will deform with the change in the weight of the raw materials. During this process, the raw materials will be lifted in the mixing chamber 101. As the amount of raw materials increases, they will fall from the discharge hole 312 to the lower side. This process is the initial mixing process.
[0034] Furthermore, in this application, in order to further improve the mixing effect, it also includes protrusions 320 that are fixedly connected to the outer wall of the guide member 310 in an annular shape at equal intervals; and a disc member 400 fixedly installed on the inner wall of the mixing tank 100. The top surface of the disc member 400 is provided with an annular bladder 410, and it also includes a compression bladder 120 that is arranged in an annular shape at equal intervals on the outer wall of the mixing tank 100. When the guide member 310 rotates, the protrusions 320 will contact the outer wall of the compression bladder 120, and the gas in the compression bladder 120 will enter the interior of the annular bladder 410. As mentioned above, during the actual mixing process, the corresponding guide 310 will rotate. At this time, the protrusion 320 fixedly connected to the outer wall of the guide 310 will intermittently squeeze the compression bladder 120. At this time, the gas in the compression bladder 120 will intermittently enter the interior of the annular bladder 410. Specifically, the corresponding annular bladder 410 will be in a state of continuous expansion and contraction. At this time, various powdered raw materials will be lifted up and then mixed again with the powder falling from the top. It should be noted that during this process, the central through hole 411 of the corresponding disc 400 will be blocked by the disk 500 to prevent unmixed raw materials from falling to the discharge port.
[0035] As one embodiment, this application also includes multiple connecting holes 401 formed inside the disc component 400, all of which are in communication with the interior of the annular bladder 410; and the multiple connecting holes 401 are in communication with the interior of the extrusion bladder 120 through connecting pipes 121. Through the connecting holes 401 and connecting pipes 121, when the protrusion 320 is released from the extrusion bladder 120, the gas inside it will enter the interior of the annular bladder 410, thereby achieving multiple vibration mixing of the raw material located on the upper side of the annular bladder 410. Correspondingly, the annular bladder 410 has a shape with a central protrusion and two concave sides. When the raw material falls from the discharge hole 312 onto the annular bladder 410, most of the raw material will be located on the outer side of the annular bladder 410, where it will be fully mixed.
[0036] Furthermore, during the mixing process, the guide 310 is an umbrella-shaped structure, and the middle of the guide 310 is aligned with the feed hole 201. When the raw material is poured from the feed hole 201 into the mixing chamber 101 inside the mixing tank 100, the raw material will scatter on the upper outer wall of the guide 310. The strip groove 311 gradually increases in diameter along the radial direction of the rotating shaft 300, and the strip groove 311 is staggered with the discharge hole 312. With this arrangement, the corresponding raw material is efficiently mixed multiple times on the upper side of the guide 310, thereby improving the mixing effect. It should also be noted that during this process, the powdered raw material will be continuously lifted and float inside the mixing chamber 101, and the various raw materials will continuously contact and expand, thereby achieving homogenization. In this way, no heat is generated during the mixing process, ensuring the stability of each raw material.
[0037] Regarding the unloading process: In this application, an unloading frame 110 is fixedly connected to the inner wall of the bottom surface of the mixing chamber 101; a movable shaft 510 is movably connected to the upper side of the unloading frame 110, and a disk 500 is provided at the upper end of the movable shaft 510, and the movable shaft 510 and the top of the unloading frame 110 are elastically connected by a spring 520. It also includes a circular hole 402 penetrating through the middle of the disk component 400, the circular hole 402 corresponding to the central notch of the annular bladder 410, for unloading; it also includes a cylindrical component 420 fixedly connected to the bottom surface of the disk component 400, with multiple fan-shaped grooves penetrating through the inner wall of the cylindrical component 420, and an electromagnetic ring 421 provided on the upper inner wall of the cylindrical component 420, which magnetically attracts the disk 500 when energized. Specifically, in the mixing stage, the electromagnetic ring 421 is connected to the external power supply. At this time, the electromagnetic ring 421 will be magnetically attracted to the disk 500, and the disk 500 will block the position of the circular hole 402. In the unloading stage: after the various raw materials are mixed for a certain period of time, the corresponding electromagnetic ring 421 will be intermittently energized and de-energized. At this time, the disk 500, which is elastically connected to the unloading frame 110, will move back and forth in the cylindrical part 420. During this process, the coating on the annular bladder 410 will fall from the fan-shaped groove to the discharge port to complete the unloading. At the same time, the disk 500, which moves back and forth in the vertical direction, will also cause the coating to be lifted up and mixed again to ensure the mixing effect between the raw materials.
[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
