[0028] The implementation manners and relevant details and working principles of the embodiments of the present utility model will be described below in conjunction with the accompanying drawings. The bag feeding mechanism of this horizontal stringing machine includes a turntable 25 and a plurality of bag receiving components 6. The plurality of bag receiving components 6 are evenly arranged along the circumferential direction of the turntable 25. The turntable 25 is provided with a bag receiving station 1, a stringing station 3, and a bag discharging station 4. A punching station 2 can also be provided between the bag receiving station 1 and the stringing station 3. Six groups of bag receiving components 6 are provided in the figure. The turntable 25 has six stations, and the redundant stations are empty stations, which can be used as spare stations to reserve positions for additional processing positions. The bag receiving component 6 includes an upper bag receiving member 7 and a lower bag receiving member 8. The upper bag receiving member 7 and the lower bag receiving member 8 respectively receive the upper bag surface and the lower bag surface of the bag body 5. At the bag receiving station 1, the lying bag body 5 is opened and sent to the bag receiving station 1. The upper bag receiving member 7 fixes the upper bag surface of the bag body 5, and the lower bag receiving member 8 fixes the lower bag surface of the bag body 5, so that the bag body 5 remains lying and the opening device is maintained. If the bag receiving station 1, the punching station 2, the stringing station 3, and the bag discharging station 4 are arranged adjacent to each other in sequence, the turntable 25 rotates, and the bag receiving component 6 at the bag receiving station 1 rotates to the punching station 2, and the bag receiving component 6 at the punching station 2 rotates to the stringing station 3. After the turntable 25 rotates one week, the bag receiving component 6 at the bag receiving station 1 sends the bag body 5 to each station, and after the bag body 5 is strung and taken off, it returns to the bag receiving station 1 to receive a new bag body 5, and so on for cyclic operation. The bag body 5 lies flat and the two bag surfaces of the bag body 5 are respectively fixed by the upper bag receiving member 7 and the lower bag receiving member 8. During the conveying process, the bag surface does not shake, the conveying is more stable, and the bag body 5 remains in an open state, so that the position of the stringing hole on the bag body 5 entering the stringing station 3 is more accurate, the stringing success rate is higher, and the upper and lower bag surfaces are symmetrical, greatly reducing the debugging difficulty.

[0029] The upper bag connecting part and the lower bag connecting part can adopt suction cups to adsorb the bag surface of the bag body 5. The upper bag connecting part and the lower bag connecting part can also adopt clamping parts for clamping the bag surface. In the attached drawing, the upper bag connecting part 7 and the lower bag connecting part 8 adopt clamping parts for clamping the bag surface. The clamping part includes a surface clamping plate 16 and an inner clamping plate 20 that can be closed or opened. The surface clamping plate 16 and the inner clamping plate 20 are closed to clamp the bag mouth of the bag surface. That is to say, the bag mouth of the bag body 5 faces the clamping part. The clamping part clamps the bag mouth of the bag body 5 to keep the position of the string hole on the bag surface stable. The surface clamping plate 16 is provided with a driving part for driving it away from the inner clamping plate 20, and the surface clamping plate 16 is connected with a second spring for closing it with the inner clamping plate 20. A stud 15 is installed on the surface clamping plate 16, and a second through hole 23 for the stud 15 to pass through is opened on the inner clamping plate 20. The driving part includes a push plate 10 that moves left and right. The pushing end of the push plate 10 is an inclined surface 11, which is slidably matched with the stud 15 on the surface clamping plate 16 of the upper bag connecting part. Then the inclined surface 11 of the push plate 10 slopes downward. When it is slidably matched with the stud 15 on the surface clamping plate 16 of the lower bag connecting part, the inclined surface 11 of the push plate 10 slopes upward. The push plate 10 moves towards the stud 15, and the pushing end presses the stud 15 to make it enter the second through hole 23. The surface clamping plate 16 is separated from the inner clamping plate 20, and the clamping part is in an open state. The bag surface of the bag body 5 extends between the surface clamping plate 16 and the inner clamping plate 20. After the push plate 10 moves in the opposite direction, the stud 15 is not pressed, and the elastic force of the second spring makes the surface clamping plate 16 and the inner clamping plate 20 press together to clamp the bag surface.

[0030] Both the inner clamping plate 20 and the surface clamping plate 16 are provided with notches 24 for the handle ropes to pass through. The clamping part clamps at the string hole of the bag body. When threading the string, the end of the handle rope passes through the notch 24 and the string hole on the bag body and is clamped by the inner clamping plate 20. The clamping part fixes the position of the string hole of the bag body, improving the success rate of string threading. And the end of the handle rope is clamped by the inner clamping plate 20 after entering the bag body 5. At the bag discharging station 4, as the bag body 5 gradually leaves the clamping part, the handle rope is pulled into the bag by the inner clamping plate 20. The earlier the inner clamping plate 20 releases the handle rope, the shorter the length of the handle rope entering the bag body 5, and vice versa. There are two string holes on one bag surface. In order to be applicable to the processing of bag bodies 5 of different specifications, both the upper bag connecting part 7 and the lower bag connecting part 8 are provided with two groups, namely the first material receiving part and the second material receiving part, and the distance between the first material receiving part and the second material receiving part can be adjusted accordingly according to the distance between the two horizontal string holes on the bag surface. The bag connecting component 6 further includes a base 9. A linear guide rail 13 is installed on the base 9. The first material receiving part and the second material receiving part are slidably arranged on the linear guide rail 13. And an adjusting screw 12 is installed on the base 9. A nut 14 is threadedly connected to the adjusting screw 12. The nut 14 is installed on the first material receiving part or the second material receiving part. Rotating the adjusting screw 12 makes the first material receiving part and / or the second material receiving part move along the linear guide rail 13 to adjust the distance between them.

[0031] The inner clamping plate 20 includes a support plate 18 and a moving plate 17 arranged vertically. The notch 24 is provided on the support plate 18. The support plate 18 contacts the inner surface of the bag surface. If the inner clamping plate 20 is the inner clamping plate 20 of the upper bag connecting member 7, the support plate 18 is above the moving plate 17. If it is the inner clamping plate 20 of the lower bag connecting member 8, the support plate 18 is below the moving plate 17. The moving plate 17 moves horizontally relative to the support plate 18 and also moves in the depth direction of the bag body 5 relative to the bag body 5, that is, in the direction of the arrow in the attached Figure 1 figure. The moving plate 17 is provided with a first through hole 22 for the handle cord to pass through. The first through hole 22 can be vertically aligned with the notch 24, and the handle cord can pass through the notch 24 and the first through hole 22 on the moving plate 17. The moving plate 17 is further provided with a punching die 21 for punching. The punching die 21 can be vertically aligned with the notch 24. Here, the punching die 21 includes cooperating with a punching knife to punch the bag body 5, and also includes cooperating with a riveting head for riveting to process the bag body 5. Riveting processing will also form a cord passing hole on the bag body. When punching, the moving plate 17 retracts relative to the bag body 5, and the punching die 21 is in the working position. At this time, the punching knife or the riveting head is pressed against the punching die 21 to perform punching operations on the bag body 5. When the handle cord is inserted, the moving plate 17 extends relative to the bag body 5, and the first through hole 22 is in the working position, and the handle cord passes through the bag body 5 and the first through hole 22 on the moving plate 17. After the handle cord is inserted, the moving plate 17 retracts relative to the bag body 5, and the handle cord is clamped by the moving plate 17 and the support plate 18. The inner clamping plate 20 of the present invention has the functions of clamping the bag, punching the bag body 5, making way for cord threading, and clamping the handle cord. The inner clamping plate 20 further includes a guiding plate 19. The support plate 18 is installed on the guiding plate 19. The guiding plate 19 is provided with a sliding groove, and the moving plate 17 is slidably arranged in the sliding groove. The sliding groove plays a guiding role to make the movement of the moving plate 17 more stable. The moving plate 17 is provided with a power member for driving it to move towards the bag body 5, and the moving plate 17 is connected with a first spring for resetting it. The punching die 21 extends into the notch 24 of the support plate 18, and the first spring drives the moving plate 17 to reset until the support plate 18 blocks the punching die 21.

[0032] The working principle of the preferred embodiment will be further described below with reference to the accompanying drawings:

[0033] At the bag receiving station 1, the push plate 10 of the bag receiving component 6 moves towards the bag body 5. The pushing end of the push plate 10 presses the pin 15, causing it to enter the second through hole 23 of the inner clamping plate 20. The surface clamping plate 16 of the upper bag receiving component 7 moves upward relative to the inner clamping plate 20, and the surface clamping plate 16 of the lower bag receiving component 8 moves downward relative to the inner clamping plate 20. The surface clamping plate 16 and the inner clamping plate 20 separate, and the clamping member opens. The upper and lower bag surfaces of the bag body 5 respectively extend between the surface clamping plate 16 and the inner clamping plate 20 of the upper and lower bag receiving components 7 and 8. The push plate 10 moves in the reverse direction, and the pin 15 is not pressed. The elastic force of the second spring causes the surface clamping plate 16 to move towards the inner clamping plate 20, and the two are pressed together to clamp the bag surface. After receiving the bag, the turntable 25 rotates, and the bag receiving component clamping the bag body 5 is rotated to the punching station 2. At this time, the moving plate 17 of the inner clamping plate 20 is in a retracted state relative to the bag body 5. The punching die 21 is at the working station. The punching knife or riveting head of the string threading machine is pressed against the punching die 21 to form a string threading hole on the bag surface, and then the punching knife and the riveting head are reset. The turntable 25 rotates again, and the bag receiving component 6 is sent to the string threading station 3. The power component drives the moving plate 17 to move towards the bottom of the bag, that is, the moving plate 17 extends relative to the bag body 5. The first through hole 22 on the moving plate 17 is at the working station. The string threading mechanism of the string threading machine clamps the handle string, and the end of the handle string passes through the notch 24 on the inner clamping plate 20, the bag body 5, and the first through hole 22 on the moving plate 17 and enters the bag. The power component is reset, and the first spring drives the moving plate 17 to retract relative to the bag body 5. The handle string entering the bag is clamped by the moving plate 17 and the support plate 18. The turntable 25 rotates to send the bag receiving component 6 to the bag discharging station 4. The push plate 10 pushes the pin 15 again, and the clamping member opens to release the bag surface. During the process of the bag body 5 separating from the bag receiving component 6, the handle string is pulled into the bag under the clamping of the moving plate 17 and the support plate 18 until the moving plate 17 and the support plate 18 release the handle string, and the bag body 5 completely separates from the bag receiving component 6, thus completing the transportation of the bag body 5.
