[0015] The utility model discloses a double-roll processing device for a tubular woven bag. An implementation mode of the utility model is specifically described below in conjunction with the accompanying drawings.
[0016] Combination Figure 1 and Figure 2 As shown, a double-roll processing device for a tubular woven bag includes a frame, a first bracket 1, a second bracket 4, a gripper mechanism 7, a first bag-holding mechanism 3, a second bag-holding mechanism 6, a sewing machine 8 and a cutting knife 9. The gripper mechanism 7, the first bag-holding mechanism 3, the second bag-holding mechanism 6, the sewing machine 8 and the cutting knife 9 are arranged in the frame, and the second bag-holding mechanism 6 is located above the first bag-holding mechanism 3. The gripper mechanism 7 is located above the first bag-holding mechanism 3, the second bag-holding mechanism 6, the sewing machine 8 and the cutting knife 9, and the gripper mechanism 7 moves up and down and left and right along the frame. In this embodiment, the structure of the first bracket 1 is the same as that of the second bracket 4, and the structure of the first bag-holding mechanism 3 is the same as that of the second bag-holding mechanism 6.
[0017] The cylindrical woven bag on the woven bag roll installed by the first bracket 1 is connected to the first bag support mechanism 3 through the first feeding mechanism 2. The first feeding mechanism 2 includes a first active roller 201 and a first passive roller 202. The first active roller 201 is located above the first passive roller 202. The rotation direction of the first active roller 201 is opposite to that of the first passive roller 202. There is a gap between the first active roller 201 and the first passive roller 202 that is adapted to the cylindrical woven bag. The first active roller 201 is driven by a motor. The first active roller 201 and the first passive roller 202 cooperate to clamp and transport the cylindrical woven bag. The operator changes the gap between the first active roller 201 and the first passive roller 202 by adjusting the first passive roller 202 to adjust the clamping force on the cylindrical woven bag.
[0018] The cylindrical woven bag on the woven bag roll mounted on the second bracket 4 is connected to the second bag-supporting mechanism 6 through the second feeding mechanism 5. The second feeding mechanism 5 includes a second active roller 501 and a second passive roller 502. The second active roller 501 is located below the second passive roller 502. The rotation direction of the second active roller 501 is opposite to that of the second passive roller 502. There is a gap between the second active roller 501 and the second passive roller 502 that is adapted to the cylindrical woven bag. The second active roller 501 is driven by a motor. The second active roller 501 cooperates with the second passive roller 502 to clamp and transport the cylindrical woven bag. The operator changes the gap between the second active roller 501 and the second passive roller 502 by adjusting the second passive roller 502 to adjust the clamping force on the cylindrical woven bag.
[0019] In this embodiment, there are two production lines, namely the first production line and the second production line. The first production line includes a first bracket 1, a first feeding mechanism 2 and a first bag-holding mechanism 3, and the second production line includes a second bracket 4, a second feeding mechanism 5 and a second bag-holding mechanism 6. The first production line and the second production line share a sewing machine 8 and a cutting knife 9. During operation, a woven bag roll is installed on the first bracket 1, and the cylindrical woven bag is connected to the first feeding mechanism 2 through a plurality of conveying rollers. The first active roller 201 cooperates with the first passive roller 202 to clamp the cylindrical woven bag and convey it to the first bag-holding mechanism 3. The operator manually opens the bag mouth of the cylindrical woven bag and puts it on the first bag-holding mechanism 3 to wait for the gripper mechanism 7 to grab it. The woven bag roll is installed on the second bracket 4, and the cylindrical woven bag is connected to the second feeding mechanism 5 through a plurality of conveying rollers. The second active roller 501 cooperates with the second passive roller 502 to clamp the cylindrical woven bag and convey it to the second bag-holding mechanism 6. The operator manually opens the bag opening of the tubular woven bag and sleeves it on the second bag-holding mechanism 6 to wait for the gripper mechanism 7 to grasp it.
[0020] like Figure 3As shown, the gripper mechanism 7 has two gripper arms, and the lower part of each gripper arm has a gripper 701. When the gripper mechanism 7 moves along the frame to the first operating position 10, the gripper 701 extends into the bag opening of the opened cylindrical woven bag placed on the first bag-supporting mechanism 3, and then the gripper arm drives the two grippers 701 to move to the two sides of the cylindrical woven bag to fix the cylindrical woven bag. The first bag-supporting mechanism 3 is closed, and the gripper mechanism 7 drives the cylindrical woven bag to move to the sewing machine 8, and the sewing machine 8 performs seam sealing on the cylindrical woven bag, and then the gripper mechanism 7 drives the cylindrical woven bag to move to the third operating position 12, and the cutting knife 9 moves to cut the already sewn cylindrical woven bag. Then the gripper mechanism 7 moves along the frame to the second operating position 11, and the gripper 701 extends into the bag opening of the opened cylindrical woven bag placed on the second bag-supporting mechanism 6, and then the gripper arm drives the two grippers 701 to move to the two sides of the cylindrical woven bag to fix the cylindrical woven bag. The second bag-supporting mechanism 6 is closed, and the gripping mechanism 7 drives the tubular woven bag to move to the sewing machine 8, which sews and seals the bottom of the tubular woven bag. Then the gripping mechanism 7 drives the tubular woven bag to move to the third operating position 12, and the cutting knife 9 moves to cut the sewn tubular woven bag.
[0021] While the gripper mechanism 7 grabs and stretches the cylindrical woven bag on the second bag-stretching mechanism 6, the cylindrical woven bag on the first production line is fed into the first bag-stretching mechanism 3 through the first feeding mechanism 2, and then the first bag-stretching mechanism 3 opens the cylindrical woven bag. While the gripper mechanism 7 grabs and stretches the cylindrical woven bag on the first bag-stretching mechanism 3, the cylindrical woven bag on the second production line is fed into the second bag-stretching mechanism 6 through the second feeding mechanism 5, and then the second bag-stretching mechanism 6 opens the cylindrical woven bag. The gripper mechanism 7 runs back and forth between the first production line and the second production line, thereby realizing the simultaneous processing of double-roll woven bags on a single processing device, effectively reducing the number of processing devices and the floor space occupied, and facilitating the improvement of production efficiency.
[0022] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
