DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0051] Embodiment 1: In some embodiments, please refer to the drawings of the specification Figure 1 and Figure 2 , a multi-cloth bagging machine, comprising a first base 10 and a second base 11;

[0052] A multi-row synchronous belt conveyor 12 for conveying cloth pieces is installed on the top of the first base 10, and a vacuum belt conveyor 13 for conveying packaging bags is installed on the top of the second base 11. A discharge inclined plate 14 is provided at the discharge end of the vacuum belt conveyor 13; the flow directions of the multi-row synchronous belt conveyor 12 and the vacuum belt conveyor 13 are vertically arranged; the multi-row synchronous belt conveyor 12 and the vacuum belt conveyor 13 both adopt mature technologies in this field, and no further elaboration is made in the description;

[0053] A cross frame 15 is fixedly mounted on the top of the second base 11, and the cross frame 15 is located between the discharge end of the multi-row synchronous belt conveyor 12 and the vacuum belt conveyor 13;

[0054] A cloth docking platform 16 is provided at the lower end of the cross frame 15, and the cloth docking platform 16 can be installed on the second base 11 in a vertically movable manner; the cloth docking platform 16 uses a cylinder as a driving force for vertical movement, and provides a limit for the vertical movement of the cloth docking platform 16 through a linear guide assembly installed on the second base 11; when the piston of the cylinder contracts, the cloth docking platform 16 is in a low position, at which time the cloth docking platform 16 is slightly lower than the highest point of the synchronous belt of the multi-row synchronous belt conveyor 12; when the piston of the cylinder extends, the cloth docking platform 16 is in a high position, at which time the cloth docking platform 16 is slightly higher than the highest point of the belt of the vacuum belt conveyor 13; the cloth docking platform 16 is used to receive the cloth on the multi-row synchronous belt conveyor 12 and then lift the cloth to facilitate the transfer of the cloth to the vacuum belt conveyor 13;

[0055] The first base 10 and the second base 11 are provided with a cloth bagging mechanism 2, and the cloth bagging mechanism 2 comprises:

[0056] A cloth pushing assembly 21, which is mounted on the first base 10 and is used to push the cloth on the high cloth docking platform 16 toward the vacuum belt conveyor 13;

[0057] The cloth side push limit follower assembly 22 is installed on the second base 11 and is located on both sides of the cloth docking platform 16. The cloth side push limit follower assembly 22 is used to assist in moving the cloth on the multi-row synchronous belt conveyor 12 to the cloth docking platform 16;

[0058] The cloth piece guiding and positioning assembly 23 is installed on the horizontal frame 15. The cloth piece guiding and positioning assembly 23 is used to shape and limit the cloth piece on the high cloth piece docking platform 16, and assist the cloth piece pushing assembly 21 to push the shaped cloth piece into the packaging bag;

[0059] The bag opening shaping component 24 is installed on the horizontal frame 15, and the bag opening shaping component 24 is used to stretch and shape the bag opening of the packaging bag that has been opened;

[0060] A bag opening assembly 25, the bag opening assembly 25 is mounted on the second base 11 and the cloth bagging mechanism 2, and the bag opening assembly 25 is used to open the bag mouth of the packaging bag;

[0061] The packaging bag limiting component 26 is installed on the second base 11. The packaging bag limiting component 26 is used to limit the packaging bag after the cloth piece is bagged, so that the position of the packaging bag containing the cloth piece will not be offset when other components are reset;

[0062] A packaging bag loading mechanism 3 is provided on the second base 11 at the feeding end of the vacuum belt conveyor 13 for transferring packaging bags one by one to the vacuum belt conveyor 13 after destacking;

[0063] An exhaust bag-supporting and sealing mechanism 4 is provided on the second base 11 at the discharge end of the vacuum belt conveyor 13 .

[0064] In the present invention, the packaging bag feeding mechanism 3 moves the packaging bags one by one to the feeding end of the vacuum belt conveyor 13, and the vacuum belt conveyor 13 moves step by step to convey the packaging bags in the direction of the discharging inclined plate 14; when the packaging bags move to the station waiting for the cloth pieces to be loaded, the bag opening of the packaging bags is opened by the bag opening component 25, and at the same time, the blowing device can be used to blow air into the packaging bags so that the packaging bags are fully opened; then the bag opening shaping component 24 extends into the bag opening of the opened packaging bags to stretch and shape the packaging belt, and the cloth piece guiding and positioning component 23 partially extends into the bag opening;

[0065] The cloth pieces are placed at the feeding end of the multi-column synchronous belt conveyor 12, and the multi-column synchronous belt conveyor 12 moves the cloth pieces to the cloth piece docking platform 16. When the cloth pieces move to the discharging end of the multi-column synchronous belt conveyor 12, the cloth piece side push limit follower assembly 22 holds the cloth pieces from both sides to position them, and assists the multi-column synchronous belt conveyor 12 to move the cloth pieces to the cloth piece docking platform 16, so as to prevent the cloth pieces from wrinkling and deforming due to being placed between the cloth piece docking platform 16 and the multi-column synchronous belt conveyor 12.

[0066] After the cloth piece is in place on the cloth piece docking platform 16, the cloth piece docking platform 16 is lifted to a high position, and the cloth piece on the cloth piece docking platform 16 is limited and shaped by the cloth piece docking platform 16 at the bottom and the cloth piece guide and positioning assembly 23 at the top. The cloth piece pushing assembly 21 supports the end of the cloth piece away from the vacuum belt conveyor 13 and pushes the cloth piece into the packaging bag under the guidance of the cloth piece guide and positioning assembly 23.

[0067] The packaging bag limiting assembly 26 presses the packaging bag onto the vacuum belt conveyor 13 to prevent the packaging bag from being offset on the vacuum belt conveyor 13 when the cloth guide positioning assembly 23 and the bag opening shaping assembly 24 are reset;

[0068] The vacuum belt conveyor 13 transfers the packaging bags that have completed the bagging operation for the cloth pieces toward the direction of the discharge inclined plate 14. When the packaging bags move to the exhaust bag support and sealing mechanism 4, the exhaust bag support and sealing mechanism 4 will exhaust the packaging bags, open the bag mouth and then seal them, thereby ensuring the packaging quality of the cloth pieces. The packaging bags that have completed the sealing and packaging operation flow out from the discharge inclined plate 14.

[0069] In the present invention, the cloth pieces and packaging bags are controlled to flow between various processes by the cooperation of the multi-row synchronous belt conveyor 12, the cloth piece docking platform 16 and the vacuum belt conveyor 13. The cloth piece pushing component 21 and the cloth piece side push limit follower component 22 cooperate to transfer the cloth pieces from the multi-row synchronous belt conveyor 12 to the cloth piece docking platform 16 and then to the vacuum belt conveyor 13, which effectively avoids the phenomenon of wrinkles or scattering of the cloth pieces during the circulation process and ensures the accurate movement of the cloth pieces.

[0070] The bag opening shaping component 24 can pre-shape the bag opening of the packaging bag so that the shape of the bag opening adapts to the cross-sectional shape of the cloth piece, and the cloth piece can be smoothly fed into the inner side of the packaging bag. At the same time, the cloth piece docking station 16 and the bag opening shaping component 24 cooperate not only to shape and limit the cloth piece again, but also the cloth piece docking station 16 can guide the cloth piece into the packaging bag, further reducing the difficulty of the cloth piece entering the packaging bag smoothly and improving the bagging quality.
