Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment for fireproof board production, specifically an automatic batching device for fireproof board production. Background Technology

[0002] Fireproof boards are decorative boards made by mixing siliceous or calcareous materials as the main raw materials with a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives, and then using autoclaving technology.

[0003] Utility model CN211246429U discloses an automatic batching device for the production of fireproof boards. The device includes a mixing tank with an opening at the top. A stirring shaft is horizontally rotatably connected inside the tank. A stirring motor is fixedly connected to one end of the tank, and the motor's main shaft extends into the tank and is fixedly connected to one end of the stirring shaft. A hopper is slidably connected inside the opening. A movable plate is fixedly connected to one side of the hopper, and the movable plate has a threaded hole. Two vertical plates are symmetrically fixedly connected to the upper side of the mixing tank, and a screw is rotatably connected between the two plates. The screw passes through the threaded hole in the movable plate and is threadedly connected. One end of the screw passes through one of the vertical plates and is fixedly connected to the end of a servo motor, which is fixedly connected to its corresponding vertical plate. This utility model uses a servo motor to drive the screw to rotate forward or backward, causing the hopper to move back and forth within the opening. The raw materials falling into the mixing tank from the bottom of the hopper are evenly distributed within the tank, improving the mixing efficiency.

[0004] However, the above-mentioned existing technology still has shortcomings in use: the bottom of the hopper is connected to the inner cavity of the mixing tank. When the hopper moves along the axial direction of the mixing tank, it can divert and introduce the ingredients in it along the axial direction of the mixing tank. However, since the hopper is in a continuous feeding state and the feeding flow is uneven, that is, when the hopper is stationary, the ingredients in it are still in a random feeding state. Therefore, the effect of evenly dispersing the ingredients into the mixing tank is poor.

[0005] Therefore, this utility model provides an automatic batching device for the production of fireproof boards. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic batching device for the production of fireproof boards, thereby solving the problems mentioned in the background section. This invention has the function of uniformly spreading materials into the mixing tank along the axial direction, and also has the function of uniformly spreading materials into the circumferential direction of the mixing tank, which greatly improves the efficiency of batching and mixing.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic batching device for fireproof board production, comprising a batching device body, the batching device body comprising a mixing tank and an axially movable hopper located at the top of the mixing tank, a rotating shaft being provided inside the hopper, a conveying spiral blade being fixedly sleeved on the outside of the rotating shaft, the conveying spiral blade being disposed near the bottom of the hopper, and a transmission assembly for transmitting rotational driving force to the rotating shaft being disposed on the outside of the hopper.

[0008] Furthermore, a sealing plate is fixedly connected to the top of the hopper, and a positioning sleeve fitted outside the rotating shaft is fixedly connected to the middle of the sealing plate. The positioning sleeve and the rotating shaft are rotatably connected, and a turnover bin is fixedly connected to one side of the hopper.

[0009] Furthermore, an inclined guide pipe is fixedly connected to one side of the hopper, the top of the inclined guide pipe is fixedly connected to the bottom of the turnover bin, and a gate is inserted into the inclined surface of the inclined guide pipe.

[0010] Furthermore, a seat plate is fixedly connected to one side of the hopper. The transmission assembly includes a drive pulley, a driven pulley, a transmission belt, and a drive shaft. The drive shaft is rotatably connected to the upper surface of the seat plate, and the drive pulley is fixedly sleeved on its top. The driven pulley is fixedly sleeved on the top of the rotating shaft and is connected to the drive pulley through the transmission belt.

[0011] Furthermore, a limiting sleeve is sleeved through the upper end face of the seat plate, and the drive shaft is sleeved inside the limiting sleeve and the two are rotatably connected by a bearing.

[0012] Furthermore, a positioning plate located on one side of the hopper is fixedly connected to the bottom of the mixing tank, a rack is fixedly connected to one side of the positioning plate, and a transmission gear that meshes with the rack is fixedly sleeved on the drive shaft.

[0013] Furthermore, the bottom of the rotating shaft is fixedly connected to a distribution plate located at the top of the mixing tank.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a rotating shaft is set inside the hopper, and a conveying spiral blade is sleeved on the rotating shaft near the bottom of the hopper. When the rotating shaft rotates, the conveying spiral blade will transfer the ingredients in the hopper downward to the mixing tank. When the rotating shaft stops rotating, the hopper will not drop materials. Thus, it has the function of controlling the dropping of materials from the hopper as needed. This can effectively reduce the time for uniform mixing in the mixing tank and greatly improve the efficiency of ingredient mixing and processing.

[0016] 2. In this utility model, a transmission assembly for transmitting rotational driving force to the rotating shaft is provided on one side of the hopper. The transmission assembly includes a drive shaft, and a rack is fixedly connected to the outer wall of the mixing tank near the top. A transmission gear that meshes with the rack is fixedly sleeved on the outside of the drive shaft. Thus, when the hopper moves along the axial direction of the mixing tank, the rotating shaft inside will be driven to rotate. Compared with the prior art, it has the advantage of automatic and uniform feeding. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: an automatic batching device for the production of fireproof boards, including a batching device body 1. The batching device body 1 includes a mixing tank 11 and a hopper 12 located on top of the mixing tank 11 and axially movable. The moving and cooperating method of the mixing tank 11 and the hopper 12 adopts the structure in the patent documents mentioned in the background art, which will not be repeated in this application. This application is an improvement solution proposed to address the shortcomings of the prior art. That is to say, other undescribed structures can adopt the structures in the prior art.

[0023] In this technical solution, a rotating shaft 2 is installed inside the hopper 12. A conveying spiral blade 3 is fixedly sleeved on the outside of the rotating shaft 2. The conveying spiral blade 3 is located near the bottom of the hopper 12. In specific implementation, the hopper 12 can be set into a conical shape. There is a small gap between the outer edge of the conveying spiral blade 3 and the inner conical wall of the hopper 12. The purpose is to prevent the material in the hopper 12 from falling along the gap between the conveying spiral blade 3 and the inner conical wall of the hopper 12. When a large amount of material needs to be continuously and evenly discharged, the rotating shaft 2 is controlled to rotate at a constant speed. The conveying spiral blade 3 uses its spiral characteristics to evenly feed the material in the hopper 12 into the mixing tank 11. When the rotating shaft 2 stops rotating, the material in the hopper 12 stops discharging. At this time, the hopper 12 is controlled to move at a constant speed along the axial direction of the mixing tank 11, while the rotating shaft 2 is controlled to rotate at a constant speed. At this time, the material in the hopper 12 will be evenly and uniformly sprinkled in the axial direction at the bottom of the mixing tank 11.

[0024] The top of the hopper 12 is fixedly connected to a sealing plate 121, and the middle of the sealing plate 121 is fixedly connected to a positioning sleeve 1211 sleeved on the outside of the rotating shaft 2. The positioning sleeve 1211 and the rotating shaft 2 are rotatably connected, and bearings can be installed on the positioning sleeve 1211 and the rotating shaft 2. A turnover bin 5 is fixedly connected to one side of the hopper 12. The turnover bin 5 is used to place the ingredients, and the ingredients are directly fed into the hopper 12 by their own weight.

[0025] Furthermore, a transmission assembly 4 for transmitting rotational driving force to the rotating shaft 2 is provided on the outer side of the hopper 12. Specifically, a seat plate 123 is fixedly connected to one side of the hopper 12. The transmission assembly 4 includes a driving pulley 41, a driven pulley 42, a transmission belt 43, and a driving shaft 44. The driving shaft 44 is rotatably connected to the upper end surface of the seat plate 123, and the driving pulley 41 is fixedly sleeved on its top. In a specific implementation, a limiting sleeve 1231 can be sleeved through the upper end surface of the seat plate 123, and the driving shaft 44 is sleeved inside the limiting sleeve 1231, with the two rotatably connected by a bearing. The driven pulley 42 is fixedly sleeved on the top of the rotating shaft 2 and is connected to the driving pulley 41 through the transmission belt 43. Thus, when the driving shaft 44 is rotated, the rotating shaft 2 rotates under the transmission of the transmission belt 43.

[0026] In this embodiment, a positioning plate 111 is fixedly connected to the bottom of the mixing tank 11 and located on one side of the hopper 12. A rack 1111 is fixedly connected to one side of the positioning plate 111. A transmission gear 441 that meshes with the rack 1111 is fixedly sleeved on the drive shaft 44. Thus, when the hopper 12 moves along the axial direction of the mixing tank 11, the transmission gear 441 rotates under the restriction of the rack 1111, thereby driving the drive shaft 44 to rotate, realizing the linkage control function of the movement of the hopper 12 and the rotation of the shaft 2.

[0027] In this embodiment, the bottom of the rotating shaft 2 is fixedly connected to the diversion plate 21 located at the top of the mixing tank 11. When the rotating shaft 2 rotates, it will drive the diversion plate 21 to rotate. The diversion plate 21 is a conical disc with the small end facing upward. After the ingredients falling from the hopper 12 land on the diversion plate 21, the diversion plate 21 will use centrifugal force to scatter them in all directions, so that the ingredients can be evenly scattered along the circumference of the mixing tank 11.

[0028] In this embodiment, an inclined guide pipe 122 is fixedly connected to one side of the hopper 12. The top of the inclined guide pipe 122 is fixedly connected to the bottom of the turnover bin 5. A gate 6 is inserted into the inclined surface of the inclined guide pipe 122. The materials in the turnover bin 5 can slide down into the hopper 12 by their own weight along the inclined slide provided by the inclined guide pipe 122. When the gate 6 is pushed up and down, the inclined guide pipe 122 can be opened and closed. After the materials in the turnover bin 5 have been transferred, closing the gate 6 can effectively prevent the discharge of pollutants generated by the mixing tank 11.

[0029] Working principle: When in use, feed ingredients into the turnover bin 5, then open the gate 6 to feed the ingredients into the hopper 12. Then control the external screw to rotate to drive the hopper 12 to move. At this time, under the restriction of the rack 1111, the transmission gear 441 rotates, which in turn drives the drive shaft 44 to rotate. The drive shaft 44 rotates to drive the drive pulley 41 to rotate. The drive pulley 41 drives the driven pulley 42 to rotate through the transmission belt 43. The driven pulley 42 drives the rotating shaft 2 to rotate, which in turn drives the conveying spiral blade 3 to rotate. The conveying spiral blade 3 rotates relative to the hopper 12 and transmits the ingredients in the hopper 12 downwards, so that the hopper 12 feeds the ingredients evenly during the movement. When the hopper 12 stops moving, it stops feeding the ingredients.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
