Description

Technical Field

[0001] The utility model provides a double-roller grinding machine for automatically separating powdery materials without materials, belongs to the field of agricultural product processing equipment, and is mainly used for grinding powdery materials. Background Art

[0002] In recent years, the market demand for condiments such as peppers has continued to increase, and the planting area has also increased day by day. After the harvest, dried peppers and other condiments are processed into pieces and then further ground; however, it is difficult to achieve all qualified particle sizes of the powdered materials after grinding, and there are often situations where the particle sizes of some powdered materials do not meet the requirements. Therefore, the powdered materials with unqualified particle sizes must be separated from them and returned to the powdered material grinder for re-grinding; the powdered materials with qualified particle sizes enter the subsequent process or are packaged.

[0003] At present, powder material grinding equipment generally adopts double-roller type, but the axes of the two rollers of the existing double-roller powder material grinding machine are fixed, so when there is no raw material feeding, the surfaces of the two rollers will be in direct contact, resulting in serious surface wear due to the mutual extrusion between the two.

[0004] Looking at the current situation of agricultural product processing equipment industry, there is an urgent need for a double-roller grinding machine for powdered materials that has good reliability, safety and reliability in grinding powdered materials and a long service life. Utility Model Content

[0005] The utility model aims to provide a double-roller grinding mill which can overcome the problems existing in the existing agricultural product processing equipment industry and has good grinding reliability, safety and reliability, and a long service life and can automatically separate powdered materials without materials.

[0006] The technical scheme is as follows: it comprises a grinding machine base, a grinding device and a grinding hopper, wherein the grinding machine base is placed on the ground, the grinding device is installed on the grinding machine base, the grinding device comprises a grinding box, a fixed grinding roller, a movable grinding roller, a grinding drive, a feeding roller, a terminal transmission and a grinding funnel, wherein the grinding box is installed on the grinding machine base, horizontally arranged slideways are arranged on the box walls on both sides of the grinding box, the two ends of the fixed grinding roller are respectively supported on the box walls of the grinding box, the two ends of the movable grinding roller are respectively inserted into the slideways of the grinding box, and the axes of the fixed grinding roller and the movable grinding roller are parallel The grinding drive is installed on the outside of the grinding box, and the protruding ends of the moving grinding roller and the fixed grinding roller after one end passes through the box wall of the grinding box are connected to the grinding drive; the two feeding rollers are supported on the box wall of the grinding box at both ends, the two feeding rollers are located above the moving grinding roller and the fixed grinding roller, and the axes of the two feeding rollers are parallel to the axes of the fixed grinding rollers, and the protruding ends of the two feeding rollers after one end passes through the box wall of the grinding box are connected to the end of the fixed grinding roller away from the grinding drive through the terminal transmission; a grinding funnel is provided under the grinding box; and the grinding hopper is installed above the grinding device.

[0007] Compared with the existing status in the art, the utility model can effectively avoid surface wear caused by mutual squeezing between the movable grinding roller and the fixed grinding roller when no-load, because the movable grinding roller can slide relative to the fixed grinding roller along the slideway on the grinding box body; because two feeding rollers are provided in the grinding machine, and the feeding rollers are located above the movable grinding roller and the fixed grinding roller, it can effectively ensure that the chili pieces to be ground in the grinding hopper are smoothly fed between the movable grinding roller and the fixed grinding roller, thereby improving the grinding efficiency.

[0011] 1. Grinding machine 11, grinding machine base 12, grinding device 121, grinding box 1211, slide 122, grinding fixed roller 123, grinding moving roller 124, grinding drive 125, feeding roller 126, terminal transmission 127, grinding funnel 13, grinding hopper.

[0012] exist Figure 1-Figure 3In the illustrated embodiment: the grinding machine base 11 of the grinding machine 1 is placed on the ground, and horizontally arranged slideways 1211 are provided on the box walls on both sides of the grinding box 121 of the grinding device 12 installed on the grinding machine base 11; both ends of the fixed grinding roller 122 are respectively supported on the box walls of the grinding box 121, and both ends of the movable grinding roller 123 are respectively inserted into the slideways 1211 of the grinding box 121, and the axes of the fixed grinding roller 122 and the movable grinding roller 123 are parallel; that is, the movable grinding roller 123 can slide relative to the fixed grinding roller 122 along the slideways 1211 on the box walls on both sides of the grinding box 121, which can effectively avoid surface wear caused by mutual extrusion between the movable grinding roller 123 and the fixed grinding roller 122 when unloaded. The grinding drive 124 is installed on the outside of the grinding box 121, and the protruding ends of the grinding roller 123 and the grinding fixed roller 122 that pass through the box wall of the grinding box 121 are connected to the grinding drive 124; the two ends of the two feeding rollers 125 are supported on the box wall of the grinding box 121, the two feeding rollers 125 are located above the grinding roller 123 and the grinding fixed roller 122, and the axes of the two feeding rollers 125 are parallel to the axes of the grinding fixed roller 122; the protruding ends of the two feeding rollers 125 that pass through the box wall of the grinding box 121 are connected to the end of the grinding fixed roller 122 away from the grinding drive 124 through the terminal transmission 126; a grinding funnel 127 is provided below the grinding box 121, and the grinding hopper 13 is installed above the grinding device 12.

[0013] Its working principle is: start the grinding drive of the "double roller mill for automatic separation of powdered materials without material" and drive the grinding roller, grinding fixed roller and feeding roller to operate. At the same time, due to the operation of the subsequent grinding feeding device, the chili pieces to be ground are continuously sent from the raw material hopper of the grinding feeding device to the grinding hopper of the grinding machine.

[0014] When the grinding feeding device sends the chili powder to be ground into the grinding hopper of the grinding machine, the grinding roller of the grinding machine automatically slides toward the grinding fixed roller, and the grinding roller and the grinding fixed roller are pressed against each other. Since the two feeding rollers of the grinding machine rotate in opposite directions and the linear speed direction of the generatrix on the two feeding rollers points to the other feeding roller, the two feeding rollers can feed the chili powder at the bottom of the grinding hopper downward to between the grinding roller and the grinding fixed roller; since the grinding roller and the grinding fixed roller of the grinding machine rotate in opposite directions and the linear speed direction of the generatrix on the grinding roller points to the grinding fixed roller, and the linear speed direction of the generatrix on the grinding fixed roller points to the grinding roller, when the feeding roller feeds the chili powder between the grinding roller and the grinding fixed roller, the grinding roller and the grinding fixed roller further crush the chili powder and drop it into the grinding funnel below. When there is no chili powder in the grinding hopper of the grinding machine, the movable grinding roller of the grinding machine will automatically slide in the direction away from the fixed grinding roller, and the movable grinding roller will separate from the fixed grinding roller, thereby effectively protecting the surfaces of the movable grinding roller and the fixed grinding roller from being worn.
