Description

Technical Field

[0001] The utility model relates to the technical field of static electricity generating devices, in particular to a static electricity generating mechanism. Background Art

[0002] In recent years, food safety has been paid more and more attention, and the control requirements for hair, braids, broom hair and other impurities mixed in food have become more and more stringent. The traditional method of removing these impurities is generally manual, but manual picking has high labor costs and heavy burdens for enterprises. Some fine dust cannot be removed, and the quality of the products after picking does not meet the requirements. Therefore, impurity removal equipment is produced. Using impurity removal equipment for picking can reduce the labor costs of enterprises and improve product quality.

[0003] At present, impurity removal equipment generally uses electrostatic adsorption to remove dust and other impurities. The electrostatic adsorption method uses an electrostatic generator to generate static electricity.

[0004] Since the electrostatic force required for different crops is different, or the electrostatic force required for different debris is also different, it is necessary to adjust the distance between the electrostatic generating roller and the crop to adjust the electrostatic force. For example, the Chinese utility model patent with application number "202021361653.X" discloses a friction charging device, which sets the electrostatic generating roller to be adjustable in lifting and lowering. Although this can effectively adjust the distance between the electrostatic roller and the material, when the two are adjusted, the electrostatic generating roller and the friction component will be displaced, and the optimal position of the friction component and the electrostatic generating roller is when the friction component is tangent to the electrostatic generating roller. After the roller position changes, the friction effect of the friction component will decrease, thereby causing the electrostatic strength to decrease. When the electrostatic generating roller moves downward, the middle part of the felt rubs against the electrostatic generating roller, and a gap is generated on the upper part of the felt. At this time, dust and debris are easily entered, causing the felt to be out of contact with the electrostatic generating roller, resulting in the phenomenon that no electrostatic adsorption force is generated.

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 In an embodiment of the utility model, an electrostatic generating mechanism includes a fixed frame 1 arranged at intervals. The electrostatic generating mechanism is used in a screening machine for screening crops. The screening machine generally has a vibrating bed. The fixed frame 1 is mounted on the vibrating bed. A sliding seat 2 that slides up and down with the fixed frame 1 is provided. An electrostatic generating roller 3 is provided between the sliding seats 2. The electrostatic generating roller 3 is located above the vibrating bed. Both ends of the electrostatic generating roller 3 are rotatably connected to the corresponding sliding seats 2. A driving component 4 that drives the two sliding seats 2 to rise and fall simultaneously is provided on the top of the fixed frame 1. A supporting frame 8 is provided on the outer side of the sliding seat 2. A hanging rod 5 is provided between the upper ends of the supporting frame 8. A felt frame 6 is hung on the hanging rod 5. A felt 7 that rubs against the electrostatic generating roller 3 is provided on the inner side of the felt frame 6.

[0022] Since the electrostatic force required for different crops is different, or the electrostatic force required for different debris is also different, it is necessary to adjust the distance between the electrostatic generating roller 3 and the crops to adjust the electrostatic force. For example, the Chinese utility model patent with application number "202021361653.X" discloses a friction charging device, which sets the electrostatic generating roller to be adjustable in lifting and lowering. Although this can effectively adjust the distance between the electrostatic roller and the material, when the two are adjusted, the electrostatic generating roller and the friction component will be displaced, and the optimal position of the friction component and the electrostatic generating roller is when the friction component is tangent to the electrostatic generating roller. After the roller position changes, the friction effect of the friction component will decrease, thereby causing the electrostatic strength to decrease. When the electrostatic generating roller 3 moves downward, the middle part of the felt 7 rubs against the electrostatic generating roller 3, and a gap is generated on the upper part of the felt 7. At this time, dust and debris are easily entered, causing the felt 7 to be out of contact with the electrostatic generating roller 3, resulting in the phenomenon that no electrostatic adsorption force is generated.

[0023] In the present application, the fixed frame 1 is arranged on the sliding seat 2, and the felt frame 6 is arranged between the fixed frames 1. When the position of the static generating roller 3 is adjusted, the fixed frame 1 will change with the position of the static generating roller 3, and the felt frame 6 and the static generating roller 3 will move together. The electrostatic adsorption force is constant and always maintains the best state.

[0024] It should be noted that a driving motor can be set at one end of the static electricity generating roller 3 to directly drive its rotation, or the static electricity generating roller 3 can be driven to rotate by a chain, sprocket, etc. This technology is existing technology and will not be repeated in this application.

[0025] Furthermore, the driving component 4 includes a cylinder, a hydraulic cylinder, and an electric push rod arranged on the top of the fixed frame 1 to drive the sliding seat 2 to move up and down.

[0026] Furthermore, the fixing frame 1 includes a bottom plate 10 and a top plate 11, two support plates 12 are spaced apart between the bottom plate 10 and the top plate 11, and slide rails 13 are formed on the support plates 12. The left and right ends of the sliding seat 2 are respectively slidably connected with the corresponding slide rails 13. The driving component 4 is arranged on the top plate 11, and the left and right ends of the sliding seat 2 are provided with sliding grooves 14, which can be slidably matched with the slide rails 13 through the sliding grooves 14.

[0027] Furthermore, the upper and lower ends of the slide rail 13 are both provided with limit blocks 15, and the limit blocks 15 can be provided to limit the position of the static electricity generating roller 3 to prevent the adjustment from being too high or too low.

[0028] Furthermore, a baffle 16 is provided between the inner sides of the support plate 12, and an opening 17 is formed on the baffle 16 for the two ends of the electrostatic generating roller 3 to pass through. By setting the baffle 16, the supporting performance of the entire fixed frame 1 can be enhanced, so that the electrostatic generating roller 3 is more stable during operation. At the same time, it can also block debris to a certain extent and prevent the debris from passing through the support plates 12.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
