DETAILED DESCRIPTION

[0021] The utility model will be described in detail below through examples, which is only used for further explaining the utility model and cannot be understood as limiting the protection scope of the utility model.

[0022] As shown in Figure 1 , Figure 2 , the instruction paper warehouse adjusting mechanism of the embodiment is installed on the instruction feeding station of the medicine packaging machine. The feeding table 2 is fixed on the rack 1, and the feeding table 2 is arranged obliquely. The material guiding assembly is symmetrically arranged on both sides of the feeding table 2. Each material guiding assembly comprises: the guide seat 3 (welded on the side wall of the feeding table 2), the guide seat 3 is provided with the square guide groove 4 (the cross section is matched with the rectangular cross section of the guide rod 5) with an upper opening; the guide rod 5 is slidably arranged through the square guide groove 4 and extends into the inside of the feeding table 2, and the outer end is limited by the cross plate 6. When the locking screw on the cross plate 6 is tightened, the position of the guide rod 5 can be fixed (the extension length of the guide rod 5 in the square guide groove 4 is adjusted, and the horizontal position of the baffle 8 assembly is coarsely adjusted).

[0023] The inner end (close to the output end of the feeding table) of the guide rod 5 is provided with the baffle 8 (symmetrically arranged on both sides of the feeding table), and the baffle 8 is fixed with the right-angled triangular positioning backplate 9 (used for positioning the side of the instruction). The two ends of the positioning backplate 9 are respectively provided with the first guide column 10. The baffle 8 is also provided with the mounting groove 11 along the length direction, and the second guide column 12 (close to the output end of the feeding table) is arranged in the mounting groove 11. The positioning backplate 9 is movably and adjustably fixed in the mounting groove 11 (the positioning backplate 9 can be moved along the length direction of the baffle 8 and fixed, and the longitudinal position of the positioning backplate 9 is adjusted). The second guide column 12 can be moved and fixed in the mounting groove 11 (the longitudinal position of the second guide column 12 is finely adjusted). The first guide column 10 and the second guide column 12 of the baffles 8 on both sides enclose the material groove 22 (the instruction paper is laid in the material groove, the width of the material groove is determined by the distance between the first guide column 10 and the second guide column 12, and the instructions of different widths are adapted).

[0024] The bottom of the baffle 8 is provided with a raised paper support strip 13 (to support the bottom of the instruction manual and prevent it from sagging and getting stuck). The inner end of the guide rod 5 is provided with a horizontal U-shaped slot, and the baffle 8 is provided with a connecting plate 15 that inserts into the U-shaped slot. The U-shaped slot is connected to the connecting plate 15 through a pin 16 (so that the baffle 8 can swing horizontally around the pin 16). The outer end of the guide rod 5 is fixed with a support plate 17, and the support plate 17 is screwed with an adjusting bolt 18. The baffle 8 is provided with a mating groove 19 that matches the adjusting bolt 18. The screw part of the adjusting bolt 18 is fitted with a compression spring 20 and then placed into the mating groove 19 (the end of the compression spring 20 abuts against the inner wall of the mating groove 19). In the initial state, the two baffles 8 open at a small "V" angle (opening angle of about 5°-15°) at the output port under the elastic force of the compression spring 20, ensuring that the instruction manual paper can be output smoothly; when it is necessary to adjust the output gap, rotating the adjusting bolt 18 can push the baffle 8 to swing around the pin 16, changing the "V" angle (in coordination with the rebound force of the compression spring 20).

[0025] When changing medicines and instruction manuals, the operator first loosens the locking screw and slides the guide rod 5 (adjusting the lateral position of the baffle 8 assembly) according to the length / width of the instruction manual paper, then tightens the locking screw to fix it; then, according to the width of the paper, the operator fine-tunes the positions of the first guide post 10 and the second guide post 12 (changing the width of the feed trough 22); finally, according to the paper thickness and conveying smoothness, the operator rotates the adjusting bolt 18 to fine-tune the "V" angle between the two baffles (optimizing the output gap). The entire process does not require disassembling the paper hopper assembly and can be completed within 3-5 minutes, significantly improving production efficiency.

[0026] During adjustment, loosen the locking screw on guide rod 5, manually push guide rod 5 along square guide groove 4 to extend or retract to the target position (adjust the lateral distance between the two baffles to match the width of the instruction manual), and then tighten the locking screw to fix guide rod 5. At the same time, rotate the adjusting bolt 18 on support plate 17 (support plate 17 is welded to the middle of guide rod 5), and push baffle 8 inward against the elastic force of compression spring 20 through the screw part (adjust the longitudinal distance between the two baffles to match the thickness of the instruction manual). After releasing, spring 20 rebounds, causing the output end of baffle 8 to open in a 5°-10° "V" shape (ensuring smooth output of the bottom instruction manual).

[0027] During operation, stacked instruction manual sheets are placed into the material trough 22, with the front end attached to the positioning plate 9, the sides limited by the first guide post 10 and the second guide post 12, and the bottom supported by the paper support strip 13. The conveyor belt 21 (synchronous belt, driven by a motor) inside the frame 1 passes directly below the output end of the feeding table 2, continuously extracting the bottom layer of instruction manuals through friction and conveying them to the subsequent packaging station. The upper layer of paper falls naturally to replenish the material due to the paper support strip 13 and the tilt angle.
