Description

Technical Field

[0001] This utility model relates to the field of colored sand production technology, specifically to a mixing and feeding device for colored sand production. Background Technology

[0002] Colored sand can be divided into four types: natural colored sand, sintered colored sand, temporarily dyed colored sand, and permanently dyed colored sand. It is generally used as a building material to enhance the artistic effect of architecture. During the production process, the raw materials need to be mixed and stirred. When the raw materials are mixed, especially after adding appropriate amounts of diluents or binders, the colored sand may appear as a paste or viscous substance. This form of colored sand is convenient for construction.

[0003] A mixing and feeding device for colored sand production, disclosed in Chinese Patent No. CN217614109U, includes a mixing tank and a frame. A sloping guide cover is fixedly connected to one side of the outer wall of the mixing tank, with an opening at the bottom. A feeding port is located on one side of the mixing tank. An arc-shaped sealing plate is movably connected to one side of the mixing tank, corresponding to the feeding port. A connecting frame is fixedly connected to one side of the arc-shaped sealing plate. A fixing frame is fixedly connected to the upper surface of the sloping guide cover. A threaded rod is movably connected to one side of the fixing frame, and a sliding block is movably connected to one side of the threaded rod. Two guide rods are provided on one side of the fixing frame, and the guide rods are movably connected to the sliding block. This invention facilitates the feeding of colored sand from the mixing tank after mixing in colored sand production. It also allows for adjustment of the feeding speed, ensuring the feeding effect and improving the production and use of colored sand.

[0004] However, the above-mentioned documents are not convenient for discharging paste-like or viscous materials after mixing, because paste-like or viscous materials tend to adhere to the inner wall of the mixing drum. The adhered materials cannot be effectively handled, resulting in material waste and affecting the next use of the mixing drum. Therefore, it is necessary to propose a mixing and discharging device for colored sand production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mixing and feeding device for colored sand production, which increases the contact area between the mixing mechanism and the material, thereby achieving efficient mixing; secondly, it can effectively remove residual material that is difficult to reach on the inner wall and bottom of the mixing drum, avoiding material waste and the purity of subsequent material mixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing and feeding device for colored sand production, comprising a fixed frame, a mixing cylinder with a sealing cover installed on its upper end face rotatably connected to the middle of the fixed frame, a mixing mechanism being provided inside the mixing cylinder; a driving mechanism being provided between the mixing cylinder and the fixed frame, and a lifting mechanism being provided on the upper end face of the fixed frame;

[0007] The driving mechanism includes a second motor installed on the outer wall of the fixed frame and fixedly connected to the stirring drum. The driving mechanism also includes a push plate disposed at the bottom of the inside of the stirring drum and an electric push rod installed at the bottom of the stirring drum and whose output end is fixedly connected to the push plate.

[0008] The stirring mechanism includes multiple horizontal bars disposed inside the stirring drum, multiple vertical bars fixedly connected to the multiple horizontal bars, and a first motor installed on the upper end face of the sealing cover, with its output end fixedly connected to the multiple horizontal bars.

[0009] As a preferred embodiment of the mixing and feeding equipment for colored sand production according to this utility model, the lifting mechanism includes a mounting plate fixedly connected to the upper end face of the fixed frame, an electric slide rail disposed on the front end face of the mounting plate, and a connecting frame slidably connected to the outer wall of the electric slide rail and fixedly connected to the sealing cover.

[0010] As a preferred embodiment of the mixing and feeding equipment for colored sand production according to this utility model, the outer wall of the push plate is fixedly connected with a rubber ring.

[0011] As a preferred embodiment of the mixing and feeding equipment for colored sand production according to this utility model, a sealing ring is installed at the contact position between the output end of the electric actuator and the mixing drum.

[0012] As a preferred embodiment of the mixing and feeding equipment for colored sand production according to this utility model, the outer wall of the fixed frame is fixedly connected with supporting legs.

[0013] As a preferred embodiment of the mixing and feeding equipment for colored sand production according to this utility model, the outer wall of the fixed frame is equipped with a control panel, and the first motor, the second motor, the first electric push rod and the electric slide rail are all electrically connected to the control panel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention first uses multiple horizontal and vertical rods to rotate and stir the material in the mixing drum. The cooperation of multiple horizontal and vertical rods increases the contact area between the mixing mechanism and the material, thereby achieving efficient mixing.

[0016] Next, the second motor drives the mixing drum to rotate, causing the opening of the mixing drum to face downwards. This allows most of the mixed material inside the mixing drum to be poured out. At the same time, the electric pusher pushes the push plate downwards inside the mixing drum, scraping off the remaining material inside the mixing drum and the material adhering to the inner wall of the mixing drum. This effectively removes the residual material that is difficult to reach on the inner wall and bottom of the mixing drum, ensuring a thorough cleaning of the inside of the mixing drum, avoiding material waste and ensuring the purity of subsequent material mixing.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] Please see Figures 1 to 4A mixing and feeding device for colored sand production includes a fixed frame 1, a mixing drum 2 with a sealing cover 205 installed on the upper end face is rotatably connected to the middle of the fixed frame 1, a mixing mechanism is provided inside the mixing drum 2, a driving mechanism is provided between the mixing drum 2 and the fixed frame 1, and a lifting mechanism is provided on the upper end face of the fixed frame 1.

[0026] The driving mechanism includes a second motor 204 installed on the outer wall of the fixed frame 1 and fixedly connected to the stirring drum 2. The driving mechanism also includes a push plate 301 disposed at the bottom of the inside of the stirring drum 2 and an electric push rod 3 installed at the bottom of the stirring drum 2 and whose output end is fixedly connected to the push plate 301.

[0027] The stirring mechanism includes multiple horizontal bars 201 disposed inside the stirring drum 2, multiple vertical bars 202 fixedly connected to the multiple horizontal bars 201, and a first motor 203 installed on the upper surface of the sealing cover 205 and whose output end is fixedly connected to the multiple horizontal bars 201.

[0028] In this embodiment: the colored sand and other materials are mixed by the mixing drum 2. Specifically, the first motor 203 is started, which drives multiple horizontal bars 201 and multiple vertical bars 202 to rotate and stir the materials in the mixing drum 2. The multiple horizontal bars 201 and multiple vertical bars 202 cooperate with each other to increase the contact area between the mixing mechanism and the materials, thereby achieving efficient mixing.

[0029] Secondly, after the materials are mixed, the second motor 204 (the second motor 204 is a worm gear self-locking motor) is started, causing the second motor 204 to drive the mixing drum 2 to rotate, causing the opening of the mixing drum 2 to face downwards, so that most of the mixed materials in the mixing drum 2 can be poured out. At the same time, the electric push rod 3 is started, causing the electric push rod 3 to push the push plate 301 to move downwards in the mixing drum 2, scraping off the remaining materials in the mixing drum 2 and the materials adhering to the inner wall of the mixing drum 2. This can effectively remove the residual materials that are difficult to reach on the inner wall and bottom of the mixing drum 2, and ensure the thorough cleaning of the inside of the mixing drum 2, avoiding waste of materials and the purity of subsequent material mixing.

[0030] As a technical optimization of this utility model, the lifting mechanism includes a mounting plate 4 fixedly connected to the upper end face of the fixed frame 1, an electric slide rail 401 disposed on the front end face of the mounting plate 4, and a connecting frame 402 slidably connected to the outer wall of the electric slide rail 401 and fixedly connected to the sealing cover 205.

[0031] In this embodiment: the electric slide rail 401 works synchronously, driving the connecting frame 402 to move upward, causing the sealing cover 205 to drive the stirring mechanism to move upward, thereby removing the stirring mechanism from the stirring drum 2, which facilitates cleaning or maintenance of the stirring mechanism.

[0032] As a technical optimization of this utility model, a rubber ring is fixedly connected to the outer wall of the push plate 301.

[0033] In this embodiment, the rubber ring can protect the inner wall of the stirring cylinder 2 and reduce the wear on the push plate 301.

[0034] As a technical optimization of this utility model, a sealing ring is installed at the contact position between the output end of the electric push rod 3 and the stirring cylinder 2.

[0035] In this embodiment, the sealing ring ensures the airtightness between the output end of the electric push rod 3 and the stirring cylinder 2.

[0036] As a technical optimization of this utility model, the outer wall of the fixing frame 1 is fixedly connected with a support leg.

[0037] In this embodiment, the equipment can be supported by support legs.

[0038] As a technical optimization of this utility model, a control panel 5 is installed on the outer wall of the fixing frame 1, and the first motor 203, the second motor 204, the first electric push rod 3 and the electric slide rail 401 are all electrically connected to the control panel 5.

[0039] In this embodiment, the first motor 203, the second motor 204, the first electric push rod 3, and the electric slide rail 401 can be controlled to work normally via the control panel 5.

[0040] Working principle: First, colored sand, thinner or adhesive and other materials are placed into the mixing drum 2 by opening the sealing cover 205. Then, the first motor 203 is started, which drives multiple horizontal bars 201 and multiple vertical bars 202 to rotate and stir the materials in the mixing drum 2. The multiple horizontal bars 201 and multiple vertical bars 202 work together to increase the contact area between the mixing mechanism and the materials, thereby achieving efficient mixing.

[0041] Secondly, after the materials are mixed, the electric slide rail 401 works synchronously, driving the connecting frame 402 to move upward, causing the sealing cover 205 to move the stirring mechanism upward, thereby removing the stirring mechanism from the mixing drum 2. Excess material on the outer wall of the stirring mechanism falls into the mixing drum 2 due to its own weight. Then, the second motor 204 (the second motor 204 is a worm gear self-locking motor) is started, causing the second motor 204 to drive the mixing drum 2 to rotate, causing the opening of the mixing drum 2 to face downward, thereby pouring out most of the mixed material in the mixing drum 2. At the same time, the electric push rod 3 is started, causing the electric push rod 3 to push the push plate 301 to move downward in the mixing drum 2, scraping off the remaining material in the mixing drum 2 and the material adhering to the inner wall of the mixing drum 2. This effectively removes the residual material that is difficult to reach on the inner wall and bottom of the mixing drum 2, ensuring the thorough cleaning of the inside of the mixing drum 2, avoiding material waste and the purity of subsequent material mixing.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
