Specific implementation manner
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0020] Refer to Figure 1-2 , a woven bag cutting device, including a housing 1, a first communication groove 2 and a chute 6 are opened in the housing 1, a cutting mechanism is arranged in the chute 6, the cutting mechanism includes a slider 7 slidably connected in the chute 6, the end of the slider 7 extends outside the chute 6, a cutting tool 8 is fixedly connected to the bottom of the slider 7. Through the arrangement of the cutting mechanism, the flattened woven bag can be cut by the sharp cutting tool 8 and the downward acting force;
[0021] A toggle mechanism is arranged in the first communication groove 2, the end of the toggle mechanism extends into the chute 6 and is fixedly connected to the side wall of the cutting mechanism. The toggle mechanism includes a limiting slide bar 3 slidably connected in the first communication groove 2, a first spring 4 is fixedly connected between the top of the limiting slide bar 3 and the inner top of the first communication groove 2, a toggle handle 5 is fixedly connected to the bottom of the limiting slide bar 3, one end of the toggle handle 5 extends outside the housing 1, and the other end of the toggle handle 5 extends into the chute 6 and is fixedly connected to the side wall of the slider 7. Through the arrangement of the toggle mechanism, after the staff drives the cutting tool 8 to operate and cut the woven bag, the first spring 4 can drive the toggle handle 5 and the cutting tool 8 to quickly reset, and the next cutting operation can be carried out without manual reset by the staff, with high work efficiency;
[0022] A flattening mechanism and a transmission mechanism are arranged on the inner side wall of the housing 1, the end of the transmission mechanism is meshed with the end of the flattening mechanism, a limiting block 9 is fixedly connected to the inner top of the housing 1, the flattening mechanism includes a servo motor 13 fixedly installed on the inner side wall of the housing 1, the end of the output shaft of the servo motor 13 is fixedly connected with a second flattening roller 14, and a second gear ring 15 is sleeved on the side wall of the second flattening roller 14;
[0023] The transmission mechanism includes a rotating rod 10 rotatably connected to the inner wall of the shell 1, and the end of the rotating rod 10 is fixedly connected to the first flattening roller 11. The side wall of the first flattening roller 11 is sleeved with a first gear ring 12, and the first gear ring 12 is meshed with the second gear ring 15. Through the setting of the flattening mechanism and the transmission mechanism, the staff can drive the second flattening roller 14 to rotate during the operation of the servo motor 13, and through the meshing relationship between the second gear ring 15 and the first gear ring 12, the first flattening roller 11 is driven to rotate in the opposite direction, so that the first flattening roller 11 and the second flattening roller 14 can cooperate with each other to flatten the woven bags passing therethrough, which is convenient for subsequent cutting processing.
[0024] The functional principle of the utility model can be explained through the following operation modes:
[0025] In the utility model, when the staff uses the utility model, the staff starts the servo motor 13 and passes the woven bag to be cut between the first flattening roller 11 and the second flattening roller 14. The start of the servo motor 13 will drive the second flattening roller 14 to rotate, and the rotation of the second flattening roller 14 will drive the second gear ring 15 to rotate. Since the second gear ring 15 is meshed with the first gear ring 12, the rotation of the second gear ring 15 will drive the first gear ring 12 to rotate in the opposite direction, thereby driving the first flattening roller 11 and the rotating rod 10 to rotate, so that the first flattening roller 11 presents a rotation direction opposite to that of the second flattening roller 14, so that the second flattening roller 14 and the first flattening roller 11 can flatten and transport the objects passing through them, so the woven bag passing through this will be affected by the first flattening roller 14. The squeezing of the flattening roller 11 and the second flattening roller 14 makes the woven bag flatter, so that the subsequent cutting process can be carried out more smoothly and the cuts on both sides of the woven bag are more uniform. The woven bag squeezed by the first flattening roller 11 and the second flattening roller 14 is restricted by gravity and the limit block 9 and placed at the inner bottom of the shell 1. The staff can position and cut the woven bag by pushing the toggle handle 5 downward. The toggle handle 5 will drive the slider 7 to move, and the slider 7 will drive the cutting tool 8 to move downward to accurately cut the flattened woven bag. After cutting, release the toggle handle 5, and the toggle handle 5 will be driven by the limit slide bar 3 to be reset by the pulling force of the first spring 4. The staff does not need to manually reset it, and the next cutting process can be carried out, which has high work efficiency.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
