The multiple snap-fitting grooves 104 on the top of the inclined connecting plate 102 are linearly arranged, and the surfaces of every two relative snap-fitting grooves 104 are snap-fitted with a limiting shaft 105. The arc surface of the limiting shaft 105 is rotatably connected to the surface of the guide roller 101 through a bearing.

[0032] Specifically implemented in this way, the guide roller 101 can ensure that the rubber sheet moves smoothly during the transportation process, reduce the shaking and deviation of the material during the transportation process, and improve the cutting accuracy; the structural design of the inclined connecting plate 102 and the L-shaped connecting plate 103 increases the stability of the entire support frame 1 and reduces the vibration that may occur during the cutting process; the cut rubber sheet is transported by the guide roller 101, which helps to neatly discharge the material and facilitates subsequent collection and packaging.

[0033] In order to realize the action of rolling and positioning the rubber sheet, a rolling conveying mechanism 11 is provided, which includes a rolling conveying roller 111.

Auxiliary shafts are fixedly installed on the opposite surfaces of the two limit plates 116. 117, the arc surface of the auxiliary shaft 117 is slidably plugged into the inner wall of the groove of the Z-shaped adjustment plate 113, and the arc surface of the auxiliary shaft 117 is rotatably connected to the auxiliary roller 118 through a bearing, and the auxiliary roller 118 is located at the bottom of the roller-pressed conveying roller 111; the opposite surfaces of the two drive boxes 5 are also fixedly installed with a threaded sleeve 119, and the threaded inner wall of the threaded sleeve 119 is threadedly connected to the adjusting screw 1110, and the tops of the four adjusting screws 1110 are rotatably connected to the support plate 1111 through bearings, and the top of the support plate 1111 is provided with an auxiliary groove 1112, and the arc of the auxiliary roller 118 is located inside the auxiliary groove 1112.

[0034] Specifically implemented in this way, the design of the roller shaft 112 allows the rubber sheet to be subjected to uniform pressure during the conveying process, which helps prevent the material from deforming during the cutting process; the design of the Z-shaped adjustment plate 113 and the vertical rod 114 allows the operator to adjust the position of the roller conveying roller 111 according to the thickness and hardness of the rubber sheet, increasing the flexibility of the equipment; the setting of the spring 115 can provide a certain buffering effect, reducing the impact caused by speed changes or material unevenness during the conveying process; this mechanism can adapt to different types of rubber sheets, regardless of thickness or hardness, and can maintain efficient conveying and positioning.

[0035] The cam 82 is actuated by a plurality of guide wheels 84 and a plurality of guide wheels 86, and the guide wheels 87 are connected to the respective guide wheels 88 and 89 to move the cam 89 in a direction of rotation.

[0036] Specifically, by replacing different numbers of upper spacers 83 and lower spacers 85, the spacing between the upper cutting blade 84 and the lower cutting blade 86 can be adjusted to achieve cutting of different sizes; the linear arrangement and distribution of the upper cutting blade 84 and the lower cutting blade 86, as well as the contact between them, ensure the accuracy and consistency of cutting; the upper cutting blade 84 and the lower cutting blade 86 are sleeved on their respective shafts, which is convenient for quick replacement of worn blades and reduces maintenance time; this mechanism can adapt to the cutting of rubber sheets of different thicknesses and materials, and is suitable for a variety of production occasions.

[0037] In order to achieve the action of adjusting the cutting of the rubber sheet according to the required cutting size during transportation, a longitudinal cutting mechanism 9 is set, including a longitudinal cutting roller 91, and a longitudinal cutting shaft 92 is fixedly installed on the surface of the longitudinal cutting roller 91.

The arc surface of the limiting shaft 96 is fixedly installed with a limiting roller 97, and the limiting roller 97 is located at the bottom of the longitudinal cutting roller 91.

[0038] Specifically, by plugging different numbers of longitudinal cutting blades 94 into the plug-in slots 93 of the longitudinal cutting roller 91, the cutting width can be easily adjusted to meet the cutting requirements of different sizes; the uniform distribution of the longitudinal cutting blades 94 on the surface of the longitudinal cutting roller 91 ensures the uniform distribution of the cutting force and improves the cutting quality; the limiting ring 95 is installed at both ends of the longitudinal cutting roller 91 through screw threads to prevent the longitudinal cutting blades 94 from falling off during operation, thereby improving the safety of operation; after the horizontal cutting of the rubber sheet is completed, it is longitudinally cut again during transportation so that the rubber sheet is cut into the required length and width, and the cutting efficiency is high.

[0039] In order to realize the synchronous driving of the transverse cutting mechanism 8, the longitudinal cutting mechanism 9 and the roller conveying mechanism 11, a connecting driving mechanism 7 is provided, which includes a first sprocket 71 and a first gear 72. One end of the roller conveying roller 111 passes through and extends to the interior of the driving box 5 and is fixedly installed on the surface of the first sprocket 71. One end of the top cutting shaft 81 passes through and extends to the interior of the driving box 5 and is fixedly installed with a second sprocket 73 and is also fixedly installed on the surface of the first gear 72. One end of the bottom cutting shaft 82 passes through and extends to The outer surface of the drive box 5 and the arc surface of one end of the bottom cutting shaft 82 are respectively fixedly mounted with the second gear 74 and the third sprocket 75, and one end of the bottom cutting shaft 82 is also fixedly mounted with the fifth sprocket 76. The second gear 74 and the third sprocket 75 are both located inside the drive box 5.

One end of the limiting shaft 105 passes through and extends to the interior of the drive box 5, and is respectively fixedly mounted with the fourth gear 78 and the fourth sprocket 79.

[0040] Specifically implemented in this way, through the cooperation of sprockets and gears, the synchronization of the horizontal cutting mechanism 8, the longitudinal cutting mechanism 9 and the roller conveying mechanism 11 during the movement is ensured, thereby improving the cutting accuracy and efficiency; by connecting the drive mechanism 7, the number of transmission components is reduced, the entire transmission system is simplified, the complexity and failure rate of the equipment are reduced, and thus the working effect of multiple mechanisms being synchronously driven by one power source is achieved.

[0041] The first sprocket 71 and the second sprocket 73 are both transmission-connected with the first chain 710, the teeth of the first gear 72 are meshed with the teeth of the second gear 74, the third sprocket 75 and the fourth sprocket 79 are both transmission-connected with the second chain 711, the teeth of the third gear 77 are meshed with the teeth of the fourth gear 78, and the fifth sprocket 76 and the driving sprocket 4 are both transmission-connected with the third chain 712.

[0042] Specifically implemented in this way, the combination of chains and gears ensures the synchronization of movement of various cutting and conveying mechanisms, avoiding errors caused by asynchronous transmission; through the combination of multiple chains and gears, the power of the drive motor 2 can be dispersed to different mechanisms, reducing the load on individual components and extending service life.

[0043] This device greatly reduces the intermediate steps in the production process through a one-time forming and cutting process, shortens the production cycle, and significantly improves the overall efficiency of the production line; it can realize automatic cutting and forming during transportation according to the length and width dimensions of the cutting; the automated cutting process reduces manual operation and material waste, reduces production costs, and improves the economic benefits of the enterprise; automatic cutting ensures the dimensional consistency of each rubber sheet and enhances the market competitiveness of the product; the equipment can quickly adapt to the cutting needs of rubber sheets of different sizes and specifications, has high flexibility, and is suitable for diversified production; through precise size control and synchronous drive system, it ensures the accuracy of cutting dimensions and improves product quality.

[0044] Working principle: During the rubber sheet cutting operation, the rubber sheet roll is controlled to be first looped around the guide roller surface at the top of the L-shaped connecting plate 103, so that one end of the rubber sheet is placed at the bottom of the roller conveyor roller 111. The driving motor 2 works under the coordination of the reducer 3 to control the rotation of the active sprocket 4, and then the roller conveyor roller 111 is controlled to rotate, squeezing the rubber sheet to convey it forward. When the front end of the rubber sheet is conveyed forward into the interior of the transverse cutting mechanism 8, the top cutting shaft 81 and the bottom cutting shaft 82 rotate synchronously, driving the upper cutting piece and the lower cutting piece to rotate and cut the rubber sheet transversely to form a long strip, and continue to convey it forward to the interior of the longitudinal cutting mechanism 9. The longitudinal cutting roller 91 is used to rotate to drive the longitudinal cutting blade 94 to cut the long strip of rubber sheet, cut it and break it, forming the required length and width for cutting, and conveyed forward into the collection position under the action of multiple guide rollers 101 at the top of the inclined connecting plate 102.
