[0025] like Figure 3 As shown, the pressing mechanism 2 includes a bracket 21, a cross bar 22, a pressing cylinder 23 and a pressing plate 24. The bracket 21 is connected to the feed frame 1, and both ends of the cross bar 22 are fixedly connected to the bracket 21. The bottom of the cross bar 22 is fixedly installed with a pressing cylinder 23, and the bottom output end of the pressing cylinder 23 is connected to the pressing plate 24.

[0026] The pressing part of the pressing plate 24 is covered with a pocket cloth 241 for preventing the pressing mechanism 2 from sticking to the tread when returning to its original position.

[0027] like Figure 4 As shown, the lifting mechanism 3 includes a mounting block 31, a positioning plate 32, a lifting cylinder 33, a bearing guide rod 34 and a cutting plate 35. The mounting block 31 is connected to the feed frame 1, and both ends of the positioning plate 32 are fixedly connected to the mounting block 31. The lifting cylinder 33 is arranged in the middle of the top wall of the positioning plate 32, and the bearing guide rod 34 is arranged on the left and right sides of the positioning plate 32. The top output end of the lifting cylinder 33 and the top end of the bearing guide rod 34 are both connected to the cutting plate 35. The lifting cylinder 31 and the bearing guide rod 34 are installed on the feed frame 1 through the mounting block 31 and are located below the tread to be cut.

[0028] The feeding frame 1 is provided with a synchronous belt module 6 for adjusting the positions of the cutting mechanism 4 and the distance measuring mechanism 5. The synchronous belt module includes a synchronous belt and a gantry. The synchronous belt is symmetrically arranged on the front and rear sides of the feeding frame 1. The driving component of the synchronous belt is connected to the cutting mechanism 4 through the gantry.

[0029] like Figure 5As shown in the figure, the cutting mechanism 4 includes a mounting plate 41, an up-and-down cutter adjusting seat 42, a left-and-right cutter adjusting seat 43, a front-and-back cutter adjusting slider 44, a fixed clamp 45, an ultrasonic cutter transducer 46, and an ultrasonic cutter 47. The mounting plate 41 is connected to the synchronous belt module 6. The up-and-down cutter adjusting seat 42 is connected to the mounting plate 41. The left-and-right cutter adjusting seat 43 is connected to the up-and-down cutter adjusting seat 42.

The ultrasonic cutter transducer 46 is installed on the fixed clamp 45. The ultrasonic cutter 47 is installed at one end of the ultrasonic cutter transducer 46. The up-and-down cutter adjusting seat 42, the left-and-right cutter adjusting seat 43, and the front-and-back cutter adjusting slider 44 are used to adjust the cutting angle and position of the ultrasonic cutter 47 on the tread. The ranging mechanism 5 includes a ranging sensor 51 and a bracket 52. The ranging sensor 51 is installed at one end of the bracket 52. The end of the bracket 52 away from the ranging sensor 51 is connected to the cutting mechanism 4. The ranging mechanism 5 is installed on the mounting plate 41 of the cutting mechanism 4. The ranging sensor 51 moves synchronously with the ultrasonic cutter 47. The cutting mechanism 4 quickly moves from startup to the starting point of cutting when detecting the tread section at a set speed. The ranging sensor 51 (laser ranging sensor) works from the cutting starting point to the shoulder section of the tread. The cutter starts to cut slowly at a set speed a. After the ranging sensor 51 (laser ranging sensor) detects a stable thickness, it starts to cut quickly at a speed b, where speed a < b. The cutting speed at the thin position of the tread is less than that at the thick position of the tread, so that the tread is not easily curled during cutting, and the quality of the tread fracture is better.

[0030] As Figure 6 shown, the feeding frame 1 includes a support plate 11, a mounting frame 12, a transmission roller group 13, and a connecting plate 14. The support plates 11 are symmetrically arranged on the front and rear sides of the feeding frame 1. The mounting frame 12 is arranged at one end of the support plate 11. The transmission roller group 13 is connected to the support plate 11 and the mounting frame 12. The connecting plate 14 is connected to the mounting frame 12.

[0031] The working principle of the present utility model: When in use, when the tread is conveyed in place, the double-guide rod cylinder (pressing cylinder 23) of the pressing cylinder cooperates with the pressing plate 24 to press down. At the same time, one lifting cylinder 31 of the lifting mechanism 3 cooperates with two bearing guide rods 34 (guide linear bearings) and the cutter plate to lift the lower part of the tread from the bottom upwards. The ultrasonic cutter 47 of the cutting mechanism 4 starts to cut. Due to the action of the upper and lower pressures, the two cut sections quickly separate from each other to both sides. After cutting is completed, the pressing mechanism 2 and the lifting mechanism 3 retract. And the cloth pocket 241 (the cloth pocket 241 is an anti-sticking PVC cloth pocket) sleeved at the bottom of the pressing plate 24 prevents the tread from sticking when the pressing cylinder 23 returns to its original position. The ultrasonic cutter 47 returns to its original position. During the process of returning to its original position, the ultrasonic cutter 47 and the cutter plate 35 are in a separated state, so as to reduce the wear of the cutter and improve the service life of the cutter.

[0032] It should be noted that the preferred implementation methods of the utility model are given in the specification and drawings of the utility model. However, the utility model can be implemented in many different forms and is not limited to the implementation methods described in the specification. These implementation methods are not used as additional restrictions on the content of the utility model. The purpose of providing these implementation methods is to make the understanding of the disclosure of the utility model more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various implementation methods not listed above, which are all regarded as the scope of the description of the utility model; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the utility model.
