Description
Technical Field
[0001] This utility model relates to the field of ingredient mixing technology, specifically to an integrated machine for mixing gypsum powder and water. Background Technology
[0002] Plaster mold precision casting is a fast and economical process for manufacturing metal molds, especially for molds with complex surfaces and intricate patterns, such as various plastic molding molds (injection molding, vacuum forming, etc.), rubber molding molds (including tire molds and shoe molds with embedded stainless steel sheets), casting molds (patterns, core boxes, etc.), and stamping dies. Because plaster mold casting can achieve high dimensional accuracy and surface finish, and there are virtually no restrictions on geometric design, machining is greatly simplified, production cycles are significantly shortened, and manufacturing costs are significantly reduced. Furthermore, it involves little or no cutting, and used molds can be recycled and reused, thus saving a significant amount of metal materials.
[0003] Gypsum powder needs to be mixed with water before use, usually using a gypsum powder mixer. However, existing mixers often leave a significant amount of gypsum residue on their inner walls after use. If not cleaned promptly, this residue will solidify, affecting future use. Currently, manual cleaning is required, which is inconvenient. Furthermore, the chemical reaction between gypsum powder and water generates heat, which accelerates solidification at higher ambient temperatures, further impacting the quality of the resulting gypsum adhesive. Therefore, there is an urgent need for an integrated gypsum powder and water mixing machine to solve these problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, the user first pours clean water into the inner cavity of the mixing tank, and then places gypsum powder into the inner cavity of the storage box.

A vertical rod is fixedly installed on the upper end of the sliding plate to stir the gypsum powder in the storage box, avoiding the blockage of the leakage hole caused by clumps of gypsum powder, and ensuring the stability of the entire device's batching process. When mixing gypsum powder with water, a water pump can be connected to inject low-temperature water into the insulation chamber through the water inlet pipe, realizing heat exchange with the high temperature inside the mixing tank, effectively reducing the setting speed of gypsum, and further improving the efficiency and quality of subsequent gypsum adhesive preparation.

[0021] Please see Figures 1-4This utility model provides a technical solution for an integrated mixing machine for gypsum powder and water:
[0022] A gypsum powder mixing and batching machine includes a mixing tank 1, an insulation cavity 11 formed on the inner wall of the mixing tank 1, a toothed ring 2 fixedly installed on the upper part of the inner side wall of the mixing tank 1, an mounting plate 3 slidably installed on the upper end face of the mixing tank 1, a mixing mechanism 4 provided on the side wall of the mounting plate 3, a central column 5 rotatably installed on the bottom surface of the inner cavity of the mixing tank 1, a storage box 6 provided on the upper end face of the central column 5, a lifting mechanism 7 provided in the middle of the lower end face of the mixing tank 1, a batching mechanism 8 provided in the inner cavity of the storage box 6, support feet fixedly installed around the lower end face of the mixing tank 1, a water outlet pipe 14 fixedly installed on the upper part of the front end face of the mixing tank 1, and a water inlet pipe 15 fixedly installed on the lower part of the front end face of the mixing tank 1.

[0023] Furthermore, the stirring mechanism 4 includes a gear 41 rotatably mounted on the lower end face of the mounting plate 3, and a stirring rod 42 fixedly mounted below the gear 41. The gear 41 meshes with the gear ring 2, and the end of the stirring rod 42 is in contact with the inner wall of the stirring tank 1. The upper end face of the mounting plate 3 is fixedly mounted with a stirring motor 43 via a frame.
[0024] The output shaft of the stirring motor 43 passes through the mounting plate 3 and is fixedly connected to the gear 41. A storage battery 44 is placed on the upper side of the mounting plate 3 near the stirring motor 43. The storage battery 44 is electrically connected to the stirring motor 43. An annular groove 12 is opened on the upper part of the outer side wall of the mixing tank 1. A limit rod 13 is slidably installed in the inner cavity of the annular groove 12. The limit rod 13 is fixedly installed on the inner side wall of the mounting plate 3.
[0025] It should be noted that the user first pours clean water into the inner cavity of the mixing tank 1, and then places the gypsum powder into the inner cavity of the storage box 6. At this time, by starting the lifting motor 75, the extension rod 71 can drive the central column 5 to rotate, and the lifting blade 76 fixedly installed on the side wall of the central column 5 will also rotate. At this time, the lifting blade 76 can drive the clean water and gypsum powder to continuously stir upward, and stir the water flow in the mixing tank 1 in a U-shape.
[0026] Furthermore, the lifting mechanism 7 includes an extension rod 71 rotatably mounted in the middle of the lower end face of the mixing tank 1, a worm gear 72 fixedly mounted on the lower end face of the extension rod 71, and vertical plates 73 fixedly mounted on the front and rear sides of the lower end face of the mixing tank 1. A worm 74 is rotatably mounted in the inner cavity of the vertical plates 73 on the front and rear sides, and the worm 74 is meshed with the worm gear 72.
[0027] A lifting motor 75 is fixedly installed on the front side of the lower end of the mixing tank 1 via a frame. The output shaft of the lifting motor 75 is fixedly connected to the worm gear 74. An extension rod 71 passes through the mixing tank 1 and is fixedly connected to the central column 5. Lifting blades 76 are fixedly installed on the side wall of the central column 5.
[0028] It should be noted that when the stirring motor 43 is started synchronously, the gear 41 rotates. The gear 41 meshes with the gear ring 2. At this time, the gear 41 will drive the stirring rod 42 to rotate. At the same time, the gear 41 can drive the stirring rod 42 to revolve along the inner wall of the mixing tank 1. The stirring rod 42 can stir the gypsum powder and water to improve the uniformity of the gypsum adhesive. On the other hand, it can scrape off the gypsum that is stuck to the inner wall of the mixing tank 1, avoiding the need for manual cleaning later.
[0029] Furthermore, the batching mechanism 8 includes a top rod 81 fixedly installed on the upper end face of the central column 5, and a sliding plate 82 fixedly installed on the upper end face of the top rod 81. The top rod 81 is connected through the storage box 6. A vertical rod 83 is fixedly installed on the upper end face of the sliding plate 82. A leakage hole 61 is opened on the lower end face of the storage box 6. The storage box 6 is fixedly installed on the outer wall of the mixing tank 1 by the bracket 62.
[0030] It should be noted that when the central column 5 rotates, it can drive the top rod 81 to rotate the sliding plate 82. As the sliding plate 82 continuously overlaps with the leakage hole 61 on the storage box 6, it can indirectly add gypsum powder into the mixing tank 1 to ensure that the powder can be completely soaked in water before stirring, thereby improving the quality of the gypsum powder stirring of the entire device. The vertical rod 83 is fixedly installed on the upper end face of the sliding plate 82, which can stir the gypsum powder in the storage box 6, avoiding the blockage of the leakage hole 61 caused by the retention of clumps of gypsum powder, and ensuring the stable operation of the entire device in terms of material preparation.
[0031] Working principle:
[0032] During operation, the user first pours clean water into the inner cavity of the mixing tank 1, and then places the gypsum powder into the inner cavity of the storage box 6. At this time, by starting the lifting motor 75, the extension rod 71 can drive the central column 5 to rotate, and the lifting blade 76 fixedly installed on the side wall of the central column 5 also rotates. At this time, the lifting blade 76 can drive the clean water and gypsum powder to continuously stir upward, and stir the water flow in the mixing tank 1 in a U-shape.
[0033] The stirring motor 43 is started synchronously, causing the gear 41 to rotate. The gear 41 meshes with the gear ring 2. At this time, the gear 41 will drive the stirring rod 42 to rotate on its own axis. At the same time, the gear 41 can drive the stirring rod 42 to revolve along the inner wall of the mixing tank 1. The stirring rod 42 can stir the gypsum powder and water to improve the uniformity of the gypsum adhesive. On the other hand, it can scrape off the gypsum that is stuck to the inner wall of the mixing tank 1, avoiding the need for manual cleaning later.
[0034] When the central column 5 rotates, it can drive the top rod 81 to rotate the sliding plate 82. As the sliding plate 82 continuously overlaps with the leakage hole 61 on the storage box 6, it can realize the function of intermittently adding gypsum powder into the mixing tank 1, so as to ensure that the powder can be completely soaked in water before stirring, thereby improving the quality of the entire device in stirring the gypsum powder. The vertical rod 83 is fixedly installed on the upper end face of the sliding plate 82, which can stir the gypsum powder in the storage box 6, avoiding the blockage of the leakage hole 61 caused by the retention of clumps of gypsum powder, and ensuring the stable operation of the entire device in dispensing.
[0035] When mixing gypsum powder and water, a water pump can be connected to inject low-temperature water into the insulation chamber 11 through the water inlet pipe 15, so as to exchange heat with the high temperature inside the mixing tank 1, effectively reducing the setting speed of gypsum and further improving the efficiency and quality of subsequent gypsum adhesive preparation.
[0036] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
