[0017] Please see Figure 1-5 The present invention provides an embodiment of a sheet feeding device, including a hopper 5. The hopper 5 has a hollow structure and is used to stack and place sheets that need to be fed. Feeding springs 6 are fixedly installed at the four corners of the hopper 5. A lifting plate 7 is fixedly installed between the tops of the four feeding springs 6. In actual use, several sheets of the same specified size can be stacked on the lifting plate 7. Furthermore, to facilitate automated sheet feeding, a drive roller 8 and a driven roller 9 are rotatably mounted on both sides of the top of the hopper 5 via bearings. The outer surfaces of the drive roller 8 and the driven roller 9 are covered with anti-slip rubber sleeves to prevent slippage during feeding. A drive wheel 10 is fixedly mounted on one end of the drive roller 8, and a synchronous wheel 11 is fixedly mounted on one end of the driven roller 9. The drive wheel 10 and the synchronous wheel 11 are connected by a synchronous belt 12. A rotary motor 13 is fixedly mounted on the outer wall of the hopper 5 at the end of the drive roller 8 away from the drive wheel 10. The output shaft of the rotary motor 13 is connected to the rotation shaft of the drive roller 8. With this structural design, the rotary motor 13 can drive the drive roller 8 to rotate. Since the drive roller 8 and the driven roller 9 are connected by a synchronous wheel structure, when the drive roller 8 rotates, it can synchronously drive the driven roller 9 to rotate in the same direction via the synchronous belt 12.

[0018] The material hopper 5 has a feeding port 14 on its front outer surface, and a material support plate 15 is fixedly installed on the outside of the feeding port 14 and on the outer wall of the material hopper 5.

[0019] Based on the above structure, when a sufficient amount of sheet material is stacked between the lifting plate 7 and the upper roller of this utility model, due to the stacking and filling effect of the sheet material, the feeding spring 6 is in a compressed state, and the uppermost sheet material is in contact with the driving roller 8 and the driven roller 9. When feeding is required, please refer to the attached instruction manual for details. Figure 1 As shown, the rotary motor 13 can rotate counterclockwise. The counterclockwise rotation of the rotary motor 13 can drive the active roller 8 and the driven roller 9 to rotate counterclockwise synchronously. During the counterclockwise rotation of the active roller 8 and the driven roller 9, the two rollers can use the friction with the sheet to feed the uppermost sheet out, so that the uppermost sheet is fed out from the feed port 14 and finally enters the support plate 15. After the top sheet is fed out, the total thickness of the stacked sheets decreases, and the compressed feed spring 6 rebounds a certain distance. Through the rebound effect of the feed spring 6, the sheet on the lifting plate 7 can be raised again, so that the sheet can contact the upper roller again. Through the automatic rebound of the feed spring 6, the actual effect of automatic rebound feeding is achieved. Under the rebound action of the feeding spring 6, the second sheet comes into contact with the upper roller again. The rotating drive roller 8 and driven roller 9 can then feed the second sheet out. The fed second sheet can abut against the first sheet on the support plate 15, thereby pushing the first sheet out and feeding it onto the external feeding conveyor belt. This completes the automated sheet feeding process.

[0020] This invention relies on the contact friction between the active roller 8 and the driven roller 9 and the sheet material to automatically feed the sheet material under rotation. By cooperating with the automatic rebound lifting characteristic of the feeding spring 6, it can achieve automated sheet material lifting and feeding characteristics. In actual use, it can automatically feed and process stacked sheets. Compared with manual feeding, this invention has higher sheet material feeding efficiency and faster speed, and does not require manual feeding, thus achieving automated feeding characteristics and effectively reducing the labor intensity of workers.

[0021] In this embodiment, in order to facilitate the replenishment of materials in the hopper 5, a feeding slot is fixedly installed on the outer wall of the tail end of the hopper 5. The outer surface of the feeding slot is detachably installed with a rear hopper plate 16 by bolts. The bolts of the rear hopper plate 16 can be removed to open the hopper 5. When replenishment is needed, the lifting plate 7 is manually pressed down, and then the sheets of the specified size are stacked on the lifting plate 7. After that, the rear hopper plate 16 is installed. Furthermore, in order to facilitate observation of the quantity of sheet material inside the hopper 5, an observation port 17 is provided in the middle of the outer surface of the rear hopper plate 16. The observation port 17 is a rectangular through-slot structure, so that the quantity of sheet material inside the hopper 5 can be directly observed through the observation port 17.

[0022] In this embodiment, in order to improve the support strength of the material support plate 15, a number of support rods for support are fixedly installed on the lower surface of the material support plate 15, and the tail ends of the support rods are fixedly connected to the outer wall of the hopper 5.

[0023] In this embodiment, in order to facilitate the adjustment of the feeding direction, a lower base 1 is provided below the hopper 5. A motor box 2 is fixedly installed on the upper surface of the lower base 1. A rotary motor 3 is fixedly installed inside the motor box 2 by bolts. A reversing turntable 4 is fixedly installed on the output shaft of the rotary motor 3. The upper surface of the reversing turntable 4 is fixedly connected to the lower surface of the hopper 5. This structural design allows the rotating motor 3 to drive the reversing turntable 4 to rotate via its output shaft. The rotation of the reversing turntable 4, in turn, drives the entire structure of the hopper 5 to rotate. In actual use, the rotation of the hopper 5 changes the feeding direction of the feeding device. This dynamic adjustability of the feeding direction makes it suitable for processing needs in different environments. It has the practical feature of dynamically adjustable feeding direction, meeting different usage conditions, effectively reducing usage limitations, and making the overall practicality stronger and the structure more flexible in use.

[0024] Working principle: The feeding device of this utility model can be opened by unscrewing the bolts of the rear chamber plate 16. When it is necessary to replenish the material, the lifting plate 7 is manually pressed down, and then the sheet material of the specified size is stacked on the lifting plate 7. After that, the rear chamber plate 16 is installed, and the sheet material loading work is completed. When a sufficient amount of sheet material is stacked between the lifting plate 7 and the upper roller of this utility model, the feeding spring 6 is in a compressed state due to the stacking and filling effect of the sheet material, and the uppermost sheet material is in contact with the driving roller 8 and the driven roller 9. When feeding is required, please refer to the attached instruction manual for details. Figure 1 As shown, the rotary motor 13 can rotate counterclockwise. The counterclockwise rotation of the rotary motor 13 can drive the active roller 8 and the driven roller 9 to rotate counterclockwise synchronously. During the counterclockwise rotation of the active roller 8 and the driven roller 9, the two rollers can use the friction with the sheet to feed out the uppermost sheet, so that the uppermost first sheet is fed out from the feed port 14 and enters the support plate 15. After the top sheet is fed out, the total thickness of the stacked sheets decreases, and the compressed feed spring 6 rebounds a certain distance. Through the rebound effect of the feed spring 6, the sheet on the lifting plate 7 can be raised again, so that the sheet can contact the upper roller again. Through the automatic rebound of the feed spring 6, the actual effect of automatic rebound feeding is achieved. Under the rebound action of the feeding spring 6, the second sheet comes into contact with the rotating roller above again. The rotating drive roller 8 and driven roller 9 can then feed the second sheet out again. The fed second sheet can abut against the first sheet on the support plate 15, thereby pushing the first sheet out and feeding it onto the external feeding conveyor belt, thus completing the automated sheet feeding process.

[0025] This invention relies on the contact friction between the active roller 8 and the driven roller 9 and the sheet material to automatically feed the sheet material under the action of rotation. By cooperating with the automatic rebound lifting characteristic of the feeding spring 6, it can have the characteristics of automated sheet material lifting and feeding. In actual use, it can automatically feed and process stacked sheets. Compared with manual feeding, this invention has higher sheet material feeding efficiency and faster speed, and does not require manual feeding. It has the characteristics of automated feeding and effectively reduces the labor intensity of workers. Furthermore, the rotating motor 3 of this utility model can drive the reversing turntable 4 to rotate through its output shaft. The rotation of the reversing turntable 4 can drive the structural assembly of the hopper 5 to rotate as a whole. In actual use, the rotation of the hopper 5 can change the feeding direction of the feeding device. Through the dynamic adjustable characteristic of the feeding direction, it can be adapted to the processing needs in different environments. It has the practical characteristic of dynamically adjustable feeding direction, meets different usage situations, effectively reduces usage limitations, has stronger overall practicality, and is more flexible in use.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
