[0004] When the above ultrasonic sewing machine is in use, due to the different sizes of container bags, the sewing positions of different-sized container bags are different when sewing the container bags, resulting in differences in the sizes of the produced container bags. Summary of the Utility Model

[0005] The utility model provides an ultrasonic sewing machine for container bag production, which solves the problem that when the ultrasonic sewing machine in the related technology is in use, due to the different sizes of container bags, the sewing positions of different-sized container bags are different when sewing the container bags, resulting in differences in the sizes of the produced container bags.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, by providing a cutting assembly, a servo motor drives a transmission belt on a transmission column for transmission, causing a connecting column on the side of a fixed block fixed to the right side of the transmission belt to move downward, and a cutting tool at the bottom of the connecting column moves to the surface of the flexible intermediate bulk container (FIBC). Through a positioning wheel, the cutting tool can precisely cut the FIBC. At the same time, a sewing device fixed to the left side of the transmission belt can alternate with the cutting tool, and after cutting, the sewing device is used for sewing. This solves the problem that when an ultrasonic sewing machine is in use, due to the different sizes of FIBCs, the sewing positions of different-sized FIBCs are different when sewing the FIBCs, resulting in differences in the sizes of the produced FIBCs. It achieves the effect that through the cutting assembly, before the sewing device sews, the sewing position of the FIBC is processed so that the sizes of the FIBCs are the same when sewing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope protected by the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 3 shown, this embodiment proposes an ultrasonic sewing machine for the production of flexible intermediate bulk containers (FIBCs), which includes a base 1. A cutting assembly 2 is fixed on the top of the base 1. A sewing device 4 is fixed in the middle of the cutting assembly 2. An automatic clamping assembly 3 is fixed on the top of the base 1;

[0028] The cutting assembly 2 includes a support column 21. A servo motor 22 is fixed on the side of the support column 21. A transmission column 24 is fixed at the output end of the servo motor 22. A transmission belt 25 is sleeved outside the transmission column 24. A fixed block 26 is fixed at the bottom right of the transmission belt 25. A connecting column 27 is fixed on the side of the fixed block 26. A support rod 28 is fixed in the connecting column 27. A connecting block 29 is fixed at the bottom of the support rod 28. A cutting tool 210 is fixed at the bottom of the connecting block 29. An external block 211 is fixed on the side of the connecting block 29. A positioning wheel 212 is rotatably connected inside the external block 211;

[0029] The sewing device 4 is fixed at the top left of the transmission belt 25. A lifting groove 23 is opened on the side of the support column 21. The transmission column 24 is rotatably connected in the lifting groove 23;

[0030] Positioning wheels 212 are fixed on both sides of the cutting tool 210. The bottom of the positioning wheel 212 is at the same level as the bottom of the cutting tool 210;

[0031] The cutting tool 210 and the sewing device 4 are staggered in the transmission belt 25.

[0032] In this embodiment, when the flexible intermediate bulk container (FIBC) with the seam to be processed is fixed on the machine, when the sizes of the FIBCs are different, the servo motor 22 drives the conveyor belt 25 to rotate counterclockwise, so that the seam device 4 on the left side of the conveyor belt 25 moves to the surface of the FIBC, and applies appropriate pressure to it. The heat energy formed by the high-frequency vibration energy generated by the ultrasonic wave is released through the concave blocks opened on the surface of the seam device 4, so that the surface of the FIBC is stitched. The servo motor 22 drives the conveyor belt 25 on the transmission column 24 to drive clockwise, so that the cutting tool 210 at the bottom of the connecting column 27 fixed to the side of the fixed block 26 fixed on the right side of the conveyor belt 25 moves to directly above the FIBC, and is assisted in positioning by the positioning wheels 212 fixed on both sides of the cutting tool 210, so that the cutting tool 210 can cut the FIBC. The cutting position of the cutting tool 210 is located outside the stitching position of the seam device 4, so that the sizes of the FIBCs are not only kept consistent, but also the stitching aesthetics of the FIBCs are improved.

[0033] Embodiment 2

[0034] As Figures 1 to 6 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the automatic clamping assembly 3 includes an orientation plate 31, an electric motor 32 is fixed to the side of the orientation plate 31, a transmission lead screw 33 is fixed to the output end of the electric motor 32, a sliding block 34 is threadedly connected to the transmission lead screw 33, a connecting rod 35 is fixed to the side of the sliding block 34, a connecting plate 36 is fixed to the other end of the connecting rod 35, a rotating shaft 37 is fixed to the other end of the connecting plate 36, and pneumatic clamping plates 38 are drivingly connected to both sides of the middle of the rotating shaft 37;

[0035] A transmission housing 39 is fixed to the side of the orientation plate 31, a transmission pulley 310 is fixed to the inside of the transmission housing 39, and a control button 311 is fixed to the side of the base 1;

[0036] A sprocket 312 is fixed between the orientation plate 31 and the electric motor 32, and a chain 313 is meshingly connected to the sprocket 312;

[0037] The number of the sliding blocks 34 is two groups, both groups of sliding blocks 34 are threadedly connected in the transmission lead screw 33, a stretching groove 314 is opened in the sliding block 34, a hydraulic rod 315 is fixed to the top of the stretching groove 314, a support block 316 is fixed to the bottom of the hydraulic rod 315, and a connecting rod 35 is fixed to the side of the support block 316.

[0038] In this embodiment, by turning on the control button 311, the staff manually places the flexible intermediate bulk container (FIBC) in the transmission housing 39, so that the FIBC can be transported by the transmission pulley 310 activated by the control button 311. The transmission pulley 310 can flatten both ends of the FIBC. The sliding block 34 on the transmission screw rod 33 is driven to move by the output end of the electric motor 32. The chain 313 meshed with the sprocket 312 fixed to the output end of the electric motor 32 causes the sliding block 34 on the other side to move synchronously, so that the pneumatic clamping plate 38 fixed to the side of the sliding block 34 moves to both ends of the FIBC. The pneumatic clamping plate 38 pneumatically clamps both ends of the FIBC in the rotating shaft 37, and the hydraulic rod 315 in the stretching groove 314 causes the pneumatic clamping plate 38 to move downward, so that both ends of the FIBC are tightened when being clamped by the pneumatic clamping plate 38, preventing the surface of the FIBC from bulging during cutting and sewing, which may affect the cutting and sewing process. When the FIBC after clamping moves to a position close to the electric motor 32 through the movement of the sliding block 34 on the transmission screw rod 33, the sewing device 4 performs the sewing process on the FIBC. When the sliding block 34 moves to the other end again, the cutting assembly 2 performs cutting treatment on the outside of the sewing part of the FIBC.

[0039] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
