Description

Technical Field

[0001] This utility model relates to the field of feed inlets, and in particular to a feed inlet structure for a talc powder grinding equipment. Background Technology

[0002] The feed inlet structure of the talc grinding equipment is a structural component that concentrates and guides the talc powder into the grinding equipment during the grinding process. It generally adopts a funnel-shaped or inclined groove design to ensure that the talc powder can smoothly enter the grinding equipment for use.

[0003] The patent document with publication number "CN222535164U" discloses "a feed inlet structure for a talc powder grinding equipment, which relates to the field of grinding equipment technology, including a square funnel-shaped hopper, a guide plate with a high center and low perimeter, four mounting plates and multiple fixing rods." Although it has the effect of "talc powder being blocked and slowed down by the guide plate and the friction of the hopper side wall, thus slowing down its speed when passing through the magnetic rod, thereby ensuring that iron impurities can be adsorbed by the magnetic rod and improving the iron removal effect," when using the feed inlet structure, the internal structure of the feed inlet is fixed when talc powder is added, and the flow speed of talc powder is fixed. However, when different particle sizes of talc powder are added, the inlet flow rate is different. The fixed structure of the feed inlet cannot control the feed amount, which leads to the problem of blockage. At the same time, the fixed feed inlet structure is also inconvenient for internal cleaning. Utility Model Content

[0004] The main purpose of this utility model is to provide a feed inlet structure for a talc powder grinding equipment, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A feed inlet structure for a talc powder grinding device includes an inlet box and a motor mounting plate. The motor mounting plate is located on one side of the inlet box. A conveying pipe is fixedly installed at the upper end of the inlet box, and a feed hopper is fixedly installed at the upper end of the conveying pipe. A drive motor is fixedly installed at the top of the motor mounting plate, and a feed outlet is fixedly installed at the lower end of the inlet box. A guide structure is provided at the center of the inlet box, and a switching handle is fixedly installed on one side of the guide structure. A spline rod is fixedly installed at one end of the shaft of the drive motor.

[0007] As a further embodiment of this utility model, the conveying pipe is arranged perpendicularly to the feed outlet, and both the conveying pipe and the feed outlet are connected to the interior of the inlet box.

[0008] As a further embodiment of this utility model, the guiding structure includes a rotary switching rod, a first baffle, a first guiding tooth, a second baffle, a second guiding tooth, a third baffle, and a third guiding tooth. The rotary switching rod is located at the center of the inlet box. The first baffle, the second baffle, and the third baffle are arranged and fixedly installed on the outside of the rotary switching rod in sequence. The first guiding tooth, the second guiding tooth, and the third guiding tooth are located on the first baffle, the second baffle, and the third baffle, respectively, and are fixedly connected to the outside of the rotary switching rod.

[0009] As a further embodiment of this utility model, the first baffle is located inside the inlet box and parallel to its two sides, the first guide tooth is located inside the inlet box, and the conveying pipe and the feed outlet are located above and below the first guide tooth, respectively.

[0010] As a further embodiment of this utility model, the switching handle is fixedly installed at one end of the rotating switching rod, and the end of the spline rod away from the drive motor is inserted into the other end of the rotating switching rod for telescopic connection.

[0011] Compared with the prior art, the present invention has the following advantages: the first guide tooth, the second guide tooth, and the third guide tooth have different tooth grooves. By rotating the switching rod to switch the first guide tooth, the second guide tooth, and the third guide tooth, the first guide tooth, the second guide tooth, and the third guide tooth with different tooth groove sizes can be set to adapt to talc powder with different particle sizes or flow rates. The large tooth groove can handle coarse particles or high flow rate materials, while the small tooth groove is suitable for fine control of the feed rate, realizing graded conveying, avoiding clogging and optimizing grinding efficiency.

[0012] Meanwhile, the telescopic connection design of the rotary switching lever and the spline lever, together with the switching handle, allows the operator to push and pull the switching lever laterally without disassembly, quickly moving the spare first guide tooth, second guide tooth and third guide tooth to the working position. This modular design greatly shortens maintenance time and improves equipment utilization.

[0013] Furthermore, when a single guide tooth is in operation, the other guide teeth are exposed, making it easier to clean and maintain the guide teeth. At the same time, when switching to neutral, it is also convenient to clean and maintain the contents of the feed box. Attached Figure Description

[0019] 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.

[0020] like Figures 1-4 As shown, this is a feed inlet structure for a talc powder grinding device. Please refer to it carefully. Figures 1-4 The system includes an inlet box 1 and a motor mounting plate 13. The motor mounting plate 13 is located on one side of the inlet box 1. A conveying pipe 2 is fixedly installed on the upper end of the inlet box 1. A feed hopper 3 is fixedly installed on the upper end of the conveying pipe 2. A drive motor 14 is fixedly installed on the top of the motor mounting plate 13. A feed outlet 4 is fixedly installed on the lower end of the inlet box 1. A guide structure 5 is provided in the center of the inlet box 1. A switching handle 16 is fixedly installed on one side of the guide structure 5. A spline rod 15 is fixedly installed on one end of the shaft of the drive motor 14.

[0021] Please refer to this carefully. Figures 1-3 The conveying pipe 2 is arranged perpendicularly to the feed outlet 4, and both the conveying pipe 2 and the feed outlet 4 are connected to the interior of the inlet box 1.

[0022] Specifically, talc powder is fed into the feed hopper 3, and the talc powder enters the conveying pipe 2 along the feed hopper 3 and then falls into the inlet box 1. The feed outlet 4 serves to discharge the talc powder in the inlet box 1 and guide the talc powder into the grinding equipment.

[0023] Please refer to this carefully. Figures 1-4 The guiding structure 5 includes a rotary switching rod 6, a first baffle 7, a first guiding tooth 8, a second baffle 9, a second guiding tooth 10, a third baffle 11, and a third guiding tooth 12. The rotary switching rod 6 is located at the center of the inlet box 1. The first baffle 7, the second baffle 9, and the third baffle 11 are arranged and fixedly installed on the outside of the rotary switching rod 6 in sequence. The first guiding tooth 8, the second guiding tooth 10, and the third guiding tooth 12 are located on the first baffle 7, the second baffle 9, and the third baffle 11, respectively, and are fixedly connected to the outside of the rotary switching rod 6.

[0024] Please refer to this carefully. Figures 1-4The first baffle 7 is located inside the inlet box 1 and parallel to its two sides. The first guide tooth 8 is located inside the inlet box 1. The conveying pipe 2 and the feed outlet 4 are located above and below the first guide tooth 8, respectively.

[0025] Specifically, the first guide tooth 8, the second guide tooth 10, and the third guide tooth 12 have different tooth groove sizes. The first baffle 7 seals both sides of the inlet box 1. After the talc powder enters the inlet box 1, it falls into the tooth groove of the first guide tooth 8. Through the rotation of the first guide tooth 8, the talc powder is quickly rolled downwards, so that the talc powder is discharged into the feed outlet 4. At the same time, when the rotating switching rod 6 is pushed and pulled, the first baffle 7 and the first guide tooth 8 can be moved out, and then the second baffle 9 and the third baffle 11 can be switched to connect with the inlet box 1, thereby replacing the second guide tooth 10 and the third guide tooth 12 with different tooth groove sizes into the inlet box 1.

[0026] Please refer to this carefully. Figures 1-2 The switching handle 16 is fixedly installed at one end of the rotating switching rod 6, and the spline rod 15, the end away from the drive motor 14, is inserted into the other end of the rotating switching rod 6 for telescopic connection.

[0027] Specifically, the operation of the drive motor 14 drives the spline rod 15 to rotate, and the spline rod 15 then drives the rotary switching rod 6 and the first guide tooth 8, the second guide tooth 10 and the third guide tooth 12 to rotate, thereby realizing the winding and guiding of talc powder. Furthermore, the spline rod 15 and the rotary switching rod 6 are telescopically connected, so the rotary switching rod 6 can be driven to rotate when it moves to different positions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
