Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

Referring to fig. 1, an ultrasonic welding machine for producing a straw comprises a workbench 1, a frame 2 vertically fixed on the workbench 1, a welding part 3 arranged on one side of the upper end of the frame 2, a support frame 4 fixed on the workbench 1, and a cushion block 5 fixed on the support frame 4. The horn of the weld 3 faces the pad 5, and the pad 5 is located directly below the weld 3.

As shown in fig. 2, the holding frame 4 is provided with a clamping assembly 6 for fixing the end of the straw, and the clamping assembly 6 comprises a mounting plate 61 fixed on the holding frame 4, pneumatic clamping jaws 62 respectively fixed at two ends of the mounting plate 61, and an upper clamping plate 63 and a lower clamping plate 64 fixed between the two pneumatic clamping jaws 62. The upper clamping plate 63 and the lower clamping plate 64 are oppositely arranged and used for clamping the Maillard tube. When the clamping assembly 6 is used, the pneumatic clamping jaw 62 controls the upper clamping plate 63 and the lower clamping plate 64 to be separated from each other, when the conveying mechanism conveys the wheat straw to between the upper clamping plate 63 and the lower clamping plate 64, the pneumatic clamping jaw 62 controls the upper clamping plate 63 and the lower clamping plate 64 to be buckled, and then the wheat straw is fixed, the middle part of the wheat straw is welded conveniently by the welding part 3, during welding, because the two ends of the wheat straw are respectively fixed by the conveying mechanism and the upper and lower clamping plates 64, therefore, the wheat straw is not easy to warp, the deformation of the wheat straw is reduced, and the quality of the wheat straw is improved.

In order to balance the lifting of the pneumatic clamping jaws 62 and the conveying mechanism and reduce the deformation of the straw, a lifting assembly 7 for controlling the lifting of the clamping assembly 6 is arranged on the supporting frame, as shown in fig. 2. The lifting assembly 7 comprises four guide posts 71, a fixing plate 72 and a driving cylinder 73, wherein one ends of the four guide posts 71 are vertically and fixedly connected with the support frame 4, the other ends of the guide posts 71 are vertically and fixedly connected with the fixing plate 72, guide holes for the four guide posts 71 to respectively penetrate through are formed in four corners of the mounting plate 61, the mounting plate 61 slides up and down along the guide posts 71, the driving cylinder 73 is fixed on the upper surface of the fixing plate 72, and a piston rod of the driving cylinder 73 penetrates through the fixing plate 72 and is fixedly connected with the mounting plate 61.
