Description

Technical Field

[0002] Non-woven bags are green products that are tough and durable, beautiful in shape, breathable, reusable, washable, can be screen-printed with advertisements and marks, and have a long service life. The product is made of non-woven fabric, which is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. For some harder non-woven bags, the bottom and sides need to be folded to ensure that they are flat and easy to store later.

[0019] Preferably, the support frame is composed of an inverted L-shaped rod and an inclined reinforcing rod, and two ends of the inclined reinforcing rod are respectively fixedly connected to the two component rods of the inverted L-shaped rod.

[0020] Preferably, the length of the rectangular plate is 1.2 times the length of the sliding rectangular frame.

[0021] Preferably, the method for using the bag sorting device for producing non-woven bags comprises the following steps:

[0022] S1: The non-woven bags to be sorted are intermittently transported through the bag conveying platform. When the non-woven bags move to the lower side of the pressing plate, the electric telescopic rod is extended to drive the fixed rectangular frame on the lower side of the fixed pressing plate to move downward and contact the top surface of the bag conveying platform. When the electric telescopic rod is extended, the inverted U-shaped support rod and the two rectangular plates at its ends are driven to move downward at the same time;

[0023] In the process of the inverted U-shaped support rod moving downward, the sliding rectangular frame first contacts the top surface of the bag transmission platform. As the rectangular plate continues to move downward, the parallel plate pushes the two sliding rectangular frames to slide relatively on the bag transmission platform, pushing the non-woven bag on the bag transmission platform to the lower side of the pressing plate. When the rectangular plate moves downward and contacts the top surface of the bag transmission platform, the two sliding rectangular frames complete the longitudinal positioning of the non-woven bag, and at this time, the sliding discs in the two sliding rectangular frames respectively contact the horizontal center lines on the left and right sides of the non-woven bag.

[0024] S2: In the process of the rectangular plate contacting the top surface of the bag transmission platform, the lateral distance between the sliding rectangular frame and the rectangular plate gradually increases, so that the sliding rectangular frame drives the second spring telescopic rod at the end of the fixed block to slide in the guide groove, and the T-shaped auxiliary pressing plate at the end of the Z-shaped plate deflects, pushing the non-woven bag to move to the side close to the fixed rectangular frame, positioning the non-woven bag in the lateral direction, and ensuring that the sliding disc in the fixed rectangular frame contacts the center line of the rear side of the non-woven bag;

[0025] S3: When the non-woven bag is completely located on the lower side of the pressing plate, the electric telescopic rod continues to extend to drive the L-shaped pushing bracket and the rectangular pressing rod thereon to move downward synchronously;

[0026] The L-shaped pushing bracket moves downward to drive the fixed pressing plate to move downward in the fixed rectangular frame and squeeze the sliding tube inside it. When the sliding tube moves downward, it drives the slider inside it to slide in the V-shaped guide groove, thereby driving the rotating driving rod to rotate in the ring tube, and driving the fixed rod on the rotating driving rod to slide between the two spiral rods, so that the sliding disc at the end of the spiral rod rotates and moves downward to fold the bottom of the non-woven bag, and then is stored in the fixed rectangular frame, so as to prevent the subsequent pressing plate at the lower end of the L-shaped pushing bracket from moving downward to squeeze the sliding disc;

[0027] Similarly, when the rectangular pressure rod moves downward, the lower pressure plate is driven to slide downward in the sliding rectangular frame, squeezing the sliding tube inside it, so that the sliding disc at the end of the spiral rod rotates downward to fold the two sides of the non-woven bag, and then is stored in the sliding rectangular frame, so as to prevent the subsequent pressure plate at the lower end of the L-shaped pushing bracket from moving downward and squeezing the sliding disc;

[0028] Then, as the electric telescopic rod continues to extend, the pressing plate is driven to continue to move downward to compact the folded non-woven bag.

[0029] S4: Finally, the electric telescopic rod is retracted to drive the pressing plate to move up and reset, and the fixed pressing plate moves up and separates from the sliding tube inside the fixed rectangular frame. At this time, the sliding tube drives the sliding tube to slide up in the rotating drive rod under the action of the slow reset force of the damping telescopic rod, and drives the rotating drive rod to rotate through the slider, so that the fixed rod slides and rotates between the two spiral rods. When the pressing plate moves up to the upper side of the fixed frame, the sliding tube is reset under the action of the damping telescopic rod, that is, the rotation and reset of the sliding disc at the end of the spiral rod inside the fixed rectangular frame are completed;

[0030] Similarly, the rectangular pressure rod moves upward to drive the lower pressure plate to move upward and slide in the sliding rectangular frame, so that the sliding disc inside the sliding rectangular frame slowly rotates and resets, and then the rectangular plate is pulled upward by the electric telescopic rod, and the parallel plate pulls the sliding rectangular frame closer to the rectangular plate, thereby releasing the limit of the sorted non-woven bag;

[0031] During the sliding of the sliding rectangular frame toward the rectangular plate, the second spring telescopic rod slides in the guide slot, so that the Z-shaped plate deflects and drives the T-shaped auxiliary pressing plate to deflect and move the sorted non-woven bag away, and finally the compressed and sorted non-woven bag is transported to the right through the bag transmission platform.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] In the present invention, two sliding rectangular frames are pushed to slide relative to each other on the bag conveying platform by parallel plates, and the non-woven bag on the bag conveying platform is pushed to the lower side of the pressure plate, thereby completing the longitudinal positioning of the non-woven bag by the two sliding rectangular frames. Then, in the process of the rectangular plate contacting the top surface of the bag conveying platform, the sliding rectangular frame drives the second spring telescopic rod at the end of the fixed block to slide in the guide groove, and causes the T-shaped auxiliary pressure plate at the end of the Z-shaped plate to deflect, thereby pushing the non-woven bag to move toward the side close to the fixed rectangular frame, positioning the non-woven bag in the horizontal direction, and ensuring the quality of the subsequent pressurization and folding of the non-woven bag by the pressure plate.

[0034] In the present invention, the L-shaped pushing bracket moves downward, driving the fixed pressing plate to move downward in the fixed rectangular frame and squeeze the sliding tube inside it. When the sliding tube moves downward, it drives the sliding block inside it to slide in the V-shaped guide groove, thereby driving the rotating driving rod to rotate in the ring tube, so that the sliding disk at the end of the spiral rod rotates and moves downward to fold the bottom of the non-woven bag, and then the non-woven bag after folding is compacted by the pressing plate, so as to avoid the problem of irregular folding at the bottom and both sides of the non-woven bag.

[0035] In the present invention, the pressure plate is driven to move up and reset by contracting the electric telescopic rod, and the fixed pressure plate moves up and separates from the sliding tube inside the fixed rectangular frame. At this time, the sliding tube drives the sliding tube to slide up in the rotating drive rod under the action of the slow reset force of the damping telescopic rod, and drives the rotating drive rod to rotate through the slider, so that the fixed rod slides and rotates between the two spiral rods. When the pressure plate moves up to the upper side of the fixed frame, the sliding tube is reset under the action of the damping telescopic rod, that is, the rotation and reset of the sliding disc at the end of the spiral rod inside the fixed rectangular frame are completed. The device reciprocates in this way to efficiently organize the non-woven bags. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The use method and advantages of the present invention: The use method of the bag sorting device for non-woven bag production, the working process is as follows:

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown:

[0067] S1: The non-woven bags to be sorted are intermittently transported through the bag conveying platform 1. When the non-woven bags move to the lower side of the pressing plate 7, the electric telescopic rod 3 is extended to drive the fixed rectangular frame 9 on the lower side of the fixed pressing plate 8 to move downward and contact the top surface of the bag conveying platform 1. When the electric telescopic rod 3 is extended, the inverted U-shaped support rod 4 and the two rectangular plates 101 at its ends are driven to move downward at the same time;

[0068] In the process of the inverted U-shaped support rod 4 moving downward, the sliding rectangular frame 103 first contacts the top surface of the bag transmission platform 1. As the rectangular plate 101 continues to move downward, the parallel plate 102 pushes the two sliding rectangular frames 103 to slide relatively on the bag transmission platform 1, and pushes the non-woven bag on the bag transmission platform 1 to the lower side of the pressing plate 7. When the rectangular plate 101 moves downward and contacts the top surface of the bag transmission platform 1, the two sliding rectangular frames 103 complete the longitudinal positioning of the non-woven bag, and at this time, the sliding discs 1210 in the two sliding rectangular frames 103 respectively contact the horizontal midlines on the left and right sides of the non-woven bag.

[0069] S2: In the process of the rectangular plate 101 contacting the top surface of the bag transmission platform 1, the lateral distance between the sliding rectangular frame 103 and the rectangular plate 101 gradually increases, so that the sliding rectangular frame 103 drives the second spring telescopic rod 113 at the end of the fixed block 114 to slide in the guide slot 112, and the T-shaped auxiliary pressing plate 115 at the end of the Z-shaped plate 111 deflects, pushing the non-woven bag to move to the side close to the fixed rectangular frame 9, positioning the non-woven bag in the lateral direction, and ensuring that the sliding disc 1210 in the fixed rectangular frame 9 contacts the center line of the rear side of the non-woven bag;

[0070] S3: When the non-woven bag is completely located at the lower side of the pressing plate 7, the electric telescopic rod 3 continues to extend to drive the L-shaped pushing bracket 6 and the rectangular pressing rod 105 thereon to move downward synchronously;

[0071] The L-shaped pushing bracket 6 moves downward to drive the fixed pressing plate 8 to move downward in the fixed rectangular frame 9 and squeeze the sliding tube 122 inside it. When the sliding tube 122 moves downward, it drives the slider 125 inside it to slide in the V-shaped guide groove 124, thereby driving the rotating driving rod 123 to rotate in the ring tube 127, and drives the fixed rod 129 on the rotating driving rod 123 to slide between the two spiral rods 1212, so that the sliding disc 1210 at the end of the spiral rod 1212 rotates downward to fold the bottom of the non-woven bag, and then is stored in the fixed rectangular frame 9, so as to prevent the pressing plate 7 at the lower end of the L-shaped pushing bracket 6 from moving downward and squeezing the sliding disc 1210;

[0072] Similarly, when the rectangular pressure rod 105 moves downward, the lower pressure plate 104 is driven to slide downward in the sliding rectangular frame 103, squeezing the sliding tube 122 inside it, so that the sliding disc 1210 at the end of the spiral rod 1212 rotates downward to fold the two sides of the non-woven bag, and then is stored in the sliding rectangular frame 103, so as to prevent the subsequent pressure plate 7 at the lower end of the L-shaped pushing bracket 6 from moving downward and squeezing the sliding disc 1210;

[0073] Then, as the electric telescopic rod 3 continues to extend, the pressing plate 7 is driven to continue to move downward, and the folded non-woven bag is compacted;

[0074] S4: Finally, the pressure plate 7 is moved upward and reset by contracting the electric telescopic rod 3, and the fixed pressure plate 8 is moved upward and separated from the slide tube 122 inside the fixed rectangular frame 9. At this time, the slide tube 122 is driven to slide upward in the rotating drive rod 123 under the action of the slow reset force of the damping telescopic rod 126, and the rotating drive rod 123 is driven to rotate through the slider 125, so that the fixed rod 129 slides and rotates between the two spiral rods 1212. When the pressure plate 7 moves up to the upper side of the fixed frame 107, the slide tube 122 is reset under the action of the damping telescopic rod 126, that is, the rotation and reset of the sliding disc 1210 at the end of the spiral rod 1212 inside the fixed rectangular frame 9 are completed;

[0075] Similarly, the rectangular pressure rod 105 moves upward to drive the lower pressure plate 104 to move upward and slide in the sliding rectangular frame 103, so that the sliding disc 1210 inside the sliding rectangular frame 103 slowly rotates and resets, and then the electric telescopic rod 3 is retracted to pull the rectangular plate 101 upward, and the parallel plate 102 pulls the sliding rectangular frame 103 closer to the rectangular plate 101, thereby releasing the limit of the sorted non-woven bag;

[0076] During the sliding process of the sliding rectangular frame 103 toward the rectangular plate 101, the second spring telescopic rod 113 slides in the guide slot 112, so that the Z-shaped plate 111 deflects and drives the T-shaped auxiliary pressing plate 115 to deflect and move the sorted non-woven bag away, and finally the compressed and sorted non-woven bag is transported to the right through the bag transmission platform 1.

8. A method for using a bag sorting device for non-woven bag production, using the bag sorting device for non-woven bag production as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1: The non-woven bags to be arranged are intermittently transported through the bag conveying platform (1). When the non-woven bags move to the lower side of the pressing plate (7), the electric telescopic rod (3) is extended to drive the fixed rectangular frame (9) on the lower side of the fixed pressing plate (8) to move downward and contact the top surface of the bag conveying platform (1). When the electric telescopic rod (3) is extended, the inverted U-shaped support rod (4) and the two rectangular plates (101) at its ends are simultaneously driven to move downward; In the process of the inverted U-shaped support rod (4) moving downward, the sliding rectangular frame (103) first contacts the top surface of the bag transmission platform (1). As the rectangular plate (101) continues to move downward, the parallel plate (102) pushes the two sliding rectangular frames (103) to slide relatively on the bag transmission platform (1), pushing the non-woven bag on the bag transmission platform (1) to the lower side of the pressing plate (7). When the rectangular plate (101) moves downward and contacts the top surface of the bag transmission platform (1), the two sliding rectangular frames (103) complete the longitudinal positioning of the non-woven bag, and at this time, the sliding discs (1210) in the two sliding rectangular frames (103) respectively contact the horizontal center lines on the left and right sides of the non-woven bag. S2: During the process of the rectangular plate (101) contacting the top surface of the bag conveying platform (1), the lateral distance between the sliding rectangular frame (103) and the rectangular plate (101) gradually increases, so that the sliding rectangular frame (103) drives the second spring telescopic rod (113) at the end of the fixed block (114) to slide in the guide groove (112), and causes the T-shaped auxiliary pressing plate (115) at the end of the Z-shaped plate (111) to deflect, pushing the non-woven bag to move toward the side close to the fixed rectangular frame (9), positioning the non-woven bag in the lateral direction, and ensuring that the sliding disc (1210) in the fixed rectangular frame (9) contacts the center line of the rear side of the non-woven bag; S3: When the non-woven bag is completely located on the lower side of the pressing plate (7), the electric telescopic rod (3) continues to extend to drive the L-shaped pushing bracket (6) and the rectangular pressing rod (105) thereon to move downward synchronously; The L-shaped pushing bracket (6) moves downward to drive the fixed pressing plate (8) to move downward in the fixed rectangular frame (9) and squeeze the sliding tube (122) inside it. When the sliding tube (122) moves downward, it drives the slider (125) inside it to slide in the V-shaped guide groove (124), thereby driving the rotating driving rod (123) to rotate in the ring tube (127) and driving the fixed rod (129) on the rotating driving rod (123) to slide between the two spiral rods (1212), so that the sliding disc (1210) at the end of the spiral rod (1212) rotates downward to fold the bottom of the non-woven bag and then is stored in the fixed rectangular frame (9), so as to prevent the pressing plate (7) at the lower end of the subsequent L-shaped pushing bracket (6) from moving downward and squeezing the sliding disc (1210); Similarly, when the rectangular pressure rod (105) moves downward, the lower pressure plate (104) is driven to slide downward in the sliding rectangular frame (103), thereby squeezing the sliding tube (122) inside the lower pressure plate (104), so that the sliding disc (1210) at the end of the spiral rod (1212) rotates downward to fold the two sides of the non-woven bag, and then is stored in the sliding rectangular frame (103), thereby preventing the pressure plate (7) at the lower end of the subsequent L-shaped pushing bracket (6) from moving downward and squeezing the sliding disc (1210); Then, as the electric telescopic rod (3) continues to extend, the pressing plate (7) is driven to continue to move downward, thereby compacting the folded non-woven bag. S4: Finally, the pressure plate (7) is moved upward and reset by contracting the electric telescopic rod (3), and the fixed pressure plate (8) is moved upward and separated from the sliding tube (122) inside the fixed rectangular frame (9). At this time, the sliding tube (122) is driven to slide upward in the rotating drive rod (123) under the action of the slow reset force of the damping telescopic rod (126), and the rotating drive rod (123) is driven to rotate through the slider (125), so that the fixed rod (129) slides and rotates between the two spiral rods (1212). When the pressure plate (7) moves up to the upper side of the fixed frame (107), the sliding tube (122 is reset under the action of the damping telescopic rod (126), that is, the rotation and reset of the sliding disc (1210) at the end of the spiral rod (1212) inside the fixed rectangular frame (9) are completed; Similarly, the rectangular pressure rod (105) moves upward to drive the lower pressure plate (104) to move upward and slide in the sliding rectangular frame (103), so that the sliding disc (1210) inside the sliding rectangular frame (103) slowly rotates and resets, and then the electric telescopic rod (3) contracts to pull the rectangular plate (101) upward, and cooperates with the parallel plate (102) to pull the sliding rectangular frame (103) closer to the rectangular plate (101), thereby releasing the limit on the sorted non-woven bag; In the process of the sliding rectangular frame (103) sliding toward the rectangular plate (101), the second spring telescopic rod (113) slides in the guide slide groove (112), so that the Z-shaped plate (111) deflects and drives the T-shaped auxiliary pressing plate (115) to deflect and move the sorted non-woven bag away, and finally the compressed and sorted non-woven bag is transported to the right through the bag transmission platform (1).
