[0027] Further description, the movement of the cutting knife 8 is limited and guided, which prevents the cutting knife 8 from deviating or shaking during lifting, ensures the linearity and stability of cutting, and improves the cutting quality and service life of the equipment.

[0028] As shown in Figure 1 , the same limiting abutting plate 17 is fixedly installed between the plurality of support plates 2.

[0029] Further illustrate, the limiting resistance board 17 is located in the frame surrounded by the conveying belt 4, the limiting resistance board 17 can ensure that the oval rubber pushing block 9 plays a supporting and positioning role in the process of conveying the conveying belt 4, and deformation or displacement of the oval rubber pushing block 9 is prevented when cutting due to stress.

[0030] As shown in Figure 1 And Figure 2 The processing table 1 is provided with a conveying mechanism, the conveying mechanism includes a plurality of fixed plates 11 fixedly installed on the processing table 1, conveying rollers 12 are rotatably connected between the two opposite fixed plates 11 and between the two opposite support plates 2, the two conveying rollers 12 in the same layer are drivingly connected through a conveying belt 13, the two conveying rollers 12 on the same side are each fixedly sleeved with a gear 14, the two gears 14 are meshedly connected, one of the conveying rollers 12 and the output shaft of the motor 10 are drivingly connected through a chain 15, the outer side walls of the two conveying rollers 12 in the same layer are each sleeved with a conveying pulley matched with the conveying belt 13, and the outer side walls of one of the conveying rollers 12 and the output shaft of the motor 10 are each sleeved with a chain disc matched with the chain 15.

[0031] Further illustrate, the conveying rollers 12 and the conveying belt 13 in the conveying mechanism are combined, the conveying rollers 12 are arranged between the two opposite fixed plates 11 and between the two opposite support plates 2, the conveying process of the PE film belt is more stable, the shaking or deviation of the material in the conveying process is reduced, and the accuracy of the cutting position is ensured.

[0032] Further illustrate, the two conveying rollers 12 on the same side are meshedly connected through the gears 14, and one of the conveying rollers 12 and the output shaft of the motor 10 are drivingly connected through the chain 15, so that the conveying mechanism and the cutting mechanism are coordinately linked. The motor 10 drives the cutting knife 8 to move, and also accurately controls the rotating speed and direction of the conveying roller 12, so that the cutting and conveying processes are seamlessly matched, and the overall working efficiency and cutting precision are further improved.

[0033] As shown in Figure 1 The length of the lower conveying belt 13 is greater than that of the upper conveying belt 13.

[0034] Further illustrate, the upper conveying belt 13 cooperates with the lower conveying belt 13 to convey and transport the PE film belt, the upper conveying belt 13 can ensure that the PE film belt is not deformed before cutting, and the lower conveying belt 13 can transport the cut PE film belt.

[0035] The function principle of the utility model can be described through the following operation modes:

[0036] First, the motor 10 is started, the motor 10 drives the shaft 3 connected with it to rotate, through the transmission belt 4 to make two shafts 3 synchronous operation, and then drive the oval rubber pushing block 9 on the transmission belt 4 to start moving.

[0037] Next, the PE film belt is placed on the two conveying belts 13 of the conveying mechanism, the motor 10 drives the conveying roller 12 below to rotate through the chain 15, under the rotation of the conveying roller 12, the two conveying belts 13 drive the PE film belt to start conveying towards the cutting knife 8, the rotation speed and direction of the conveying roller 12 are coordinated with the movement of the cutting knife 8, to ensure that the PE film belt moves stably towards the cutting area.

[0038] When the PE film belt reaches the cutting area, the oval rubber pushing block 9 on the outer side wall of the conveying belt 4 and the oval rubber pushing block 9 on the top of the lifting plate 7 come into contact with each other, due to the deformability of rubber, the extrusion between the oval rubber pushing blocks 9 makes the lifting plate 7 overcome the elastic force of the spring 18 to move downward, thereby driving the cutting knife 8 to cut the PE film belt downward, during the cutting process, the cutting knife 8 slides along the inner side wall of the limiting groove plate 16 to ensure the linearity and stability of the cutting, and the limiting resistance plate 17 supports and positions the oval rubber pushing block 9 to prevent it from being deformed or displaced under stress.

[0039] After cutting, with the continuous rotation of the conveying belt 4, the interaction between the oval rubber pushing blocks 9 disappears, under the action of the spring 18, the lifting plate 7 drives the cutting knife 8 to rise to the initial position, preparing for the next cutting, the conveying belt 13 below will convey the cut PE film belt, and the conveying belt 13 above will continue to keep the subsequent PE film belt to be cut not deformed and stably conveyed before cutting.
