Technical Field

[0001] The invention relates to the field of ceramic production equipment, and in particular to a feed control device of a ceramic material distribution machine. Background Art

[0002] In the ceramic production process, a material distribution machine is required for material distribution. When the material distribution machine distributes materials, powder is provided to the material distribution mechanism through a feed control device. The existing feed control device uses a rotating hopper gate to control the opening and closing of the discharge port. When closing, it is easy to be stuck by powder, resulting in a loose closure. In addition, the existing feed control device only has a vertical baffle. Due to the structural reasons of the hopper gate, there is a certain height distance between the powder and the distribution plane when the material is discharged. The powder falls freely, the side of the powder spreads freely, and the cross-sectional shape of the powder is a trapezoid. The existing technology cannot accurately control the width of the discharge port of the powder and the shape of the edges on both sides of the powder. For belt-type distribution, the width of the discharge port is required to be more accurately adjusted to avoid waste of powder. In particular, for roller forming presses, there are certain requirements for the shape and angle of the side of the cloth. The existing feed control device cannot meet the current needs of belt-type distribution for tile production. Summary of the invention

[0004] In order to solve the above technical problems, the embodiment of the present invention provides a feed control device for a ceramic feeder, including a storage hopper, a feed baffle, an extension baffle, a cylinder, a limit adjustment block, a discharge plate, a discharge auxiliary plate, a scraper plate and a vertical baffle; the storage hopper is provided with a discharge port at the lower end; the vertical baffle is arranged in the storage hopper, the discharge plate is provided with an avoidance port, the vertical baffle extends from the discharge port and is connected to the feed baffle located below the discharge plate, and the extension baffle is connected to the feed baffle; the discharge auxiliary plate partially overlaps the discharge plate, and one end thereof is connected to the feed baffle; the feed baffle and the vertical baffle are connected and can move left and right together, and at the same time drive the discharge auxiliary plate to move synchronously to control the discharge port width of the storage hopper. The extension baffle moves left and right synchronously with the feed baffle to maintain the powder conveying. The inner side of the material-cutting stop bar and the extension stop bar is processed into a specific shape according to the needs of the formed brick blank to control the side shape and angle of the powder. Generally, the inner side shape of the material-cutting stop bar is a slope or a slope with straight edges.

[0005] As an improvement of the above solution, the discharge plate includes a discharge baffle and an arc-shaped groove located above the discharge baffle.

[0006] As an improvement of the above solution, the surface of the discharge plate is arc-shaped, and its curvature matches the arc-shaped groove; the discharge auxiliary plate is located in the arc-shaped groove and can move left and right in the arc-shaped groove.

[0007] As an improvement of the above solution, a limiting hook is provided on the vertical baffle plate, and a limiting groove is provided on the discharge auxiliary plate, and the limiting groove is arranged along the swinging direction of the discharge plate.

[0008] As an improvement of the above solution, the limiting hook extends into the limiting groove, and the vertical baffle can drive the discharge auxiliary plate to move left and right through the limiting hook to control the discharge width.

It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0026] like Figure 1-Figure 6 As shown, a specific embodiment of the present invention provides a feed control device for a ceramic material distribution machine, including a storage hopper 1, a feed stop bar 2, an extension stop bar 3, a cylinder 4, a limit adjustment block 5, a discharge plate 6, a discharge auxiliary plate 7, a scraper plate 8, and a vertical baffle 9; the storage hopper 1 is provided with a discharge port 11 at the lower end; the vertical baffle 9 is arranged in the storage hopper 1, and the discharge plate 6 is provided with a avoidance port 61, and the vertical baffle 9 extends from the discharge port 11 and is connected to the feed stop bar 2 located below the discharge plate 6; the discharge auxiliary plate 7 partially overlaps with the discharge plate 6, and one end thereof is connected to the feed stop bar 2; the feed stop bar 2 is connected to the vertical baffle 9 and can be moved left and right synchronously to control the discharge port width of the storage hopper 1. The feed stop bar 2 is connected to the extension stop bar 3 and can be moved left and right synchronously to maintain the powder conveying. The unloading baffle 2 and the vertical baffle 9 move left and right, and drive the discharging auxiliary plate 7 to move synchronously. The discharging auxiliary plate 7 also swings with the discharging plate 6 to control the opening and closing of the discharging plate. The scraper plate 8 is used to scrape the powder discharged from the discharging port 11. It can be arranged on one side of the discharging port of the storage hopper 1, or it can be fixed separately above the conveyor belt.

[0027] Among them, Figure 7 As shown, the vertical baffle plate 9 is provided with a limit hook 91, and the discharging auxiliary plate 7 is provided with a limit groove 71. The limit groove 71 is arranged along the swinging direction of the discharging plate 6. The limit hook 91 extends into the limit groove 71, and the vertical baffle plate 9 can drive the discharging auxiliary plate 7 to move left and right through the limit hook 91 to control the discharging width. With the above structure, when the discharging plate swings to adjust the opening of the discharging port 11, the discharging auxiliary plate 7 can move a predetermined distance relative to the unloading stop bar 2 to meet the comprehensive adjustment of the width and opening of the discharging port 11.

[0028] According to the present solution, the vertical baffle 9 is arranged in the storage hopper 1, and the discharge plate 6 is provided with an avoidance opening 61. The vertical baffle 9 extends from the discharge port 11 and is connected to the discharge stop bar 2 located below the discharge plate 6; the discharge auxiliary plate 7 partially overlaps the discharge plate 6, and one end thereof is connected to the discharge stop bar 2; the vertical baffle 9 can move left and right, driving the discharge auxiliary plate 7 and the discharge stop bar 2 to move synchronously, so as to control the discharge port width of the storage hopper 1. When the discharge port width needs to be adjusted, the discharge width of the discharge port 11 can be controlled by manually pulling the vertical baffle 9 or by an automatic mechanism driving the vertical baffle 9, the discharge stop bar 2 and the discharge auxiliary plate 7 to move together. The powder discharge width is consistent with the distance between the left and right discharge stop bars, and the shape angles of the two sides are consistent with the shape angles of the inner side surfaces of the discharge stop bars. When the front and rear opening of the discharge port needs to be adjusted, the discharge plate 6 can be pushed forward and backward by the cylinder 4, and the swing angle of the discharge plate 6 can be adjusted by the limit adjustment block 5. In this way, the discharge width and the side shape and side angle of the powder can be accurately controlled, and the discharge amount can be controlled by adjusting the opening of the discharge port. It meets the requirements of brick layout of different sizes, has a compact structure, stable and reliable operation, and is easy to maintain.

[0029] Preferably, the discharge plate 6 includes a discharge baffle 62 and an arc groove 63 located above the discharge baffle 62. The surface of the discharge plate 6 is arc-shaped, and its curvature matches the arc groove 63; the discharge plate 6 is located in the arc groove 63 and can move left and right in the arc groove 63.

[0030] Preferably, the discharge plate 6 is connected to the storage hopper 1 through a swing arm 64, and the swing arm 64 is driven by the cylinder 4 and can drive the discharge plate 6 to swing back and forth. The discharge plate 6 controls the opening and closing of the storage hopper 1 through the circular motion, is not easily stuck by the powder, and moves more smoothly.

[0031] In order to ensure that the width center of the powder delivered by the storage hopper 1 is at the same position after adjusting the width, the vertical baffle 9, the unloading baffle bar 2 and the discharge auxiliary plate 7 are symmetrically arranged in the storage hopper 1. When adjusting the width, the unloading baffle bars 2 on both sides are manually adjusted to the same distance to ensure that the width center of the discharge port is at the same position. More preferably, in order to make the width adjustment more intelligent and convenient, the vertical baffles 9 and the unloading baffle bar 2 on both sides of the storage hopper 1 are connected to a synchronous moving mechanism (not shown in the figure). When the vertical baffles 9 and the unloading baffle bar 2 on one side are moved, the synchronous moving mechanism can drive the vertical baffles 9 and the unloading baffle bar 2 on the other side to move the same displacement. With the above structure, the worker or the driving mechanism only needs to drive the vertical baffle 9 and the unloading baffle bar 2 on one side, and the width control bar on the other side can move synchronously, thereby ensuring the reliability of the discharge position from the mechanical structure.

[0032] Specifically, the synchronous movement mechanism can be a rack connected to two vertical baffles 9 at different positions, the tooth surfaces of the rack are arranged opposite to each other, and the two racks are connected by a synchronous gear. When one rack is driven, the synchronous gear will be driven to rotate, thereby driving the rack on the other side to move the same distance.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
