Since the two transmission wheels 3 16 are connected by a transmission member 17, the two threaded rods 14 can be driven to rotate at the same time. Due to the threaded fit between the mounting frame 13 and the threaded rod 14, the rotation of the threaded rod 14 can make the mounting frame 13 slide back and forth vertically along the path of the threaded rod 14. During the sliding process of the mounting frame 13, a sliding fit is formed between the transmission gear 3 24 and the guide rail 22, and finally the spacing between the feed roller 1 21 and the feed roller 2 30 is adjusted.

[0055] An elastic member 34, wherein the elastic member 34 is sleeved on one end of the connecting rod 32, and both ends of the elastic member 34 are fixedly connected to the connecting rod 32 and the fixing plate 26 respectively;

[0056] See also Figure 1 In one embodiment, the linkage component includes:

[0057] A transmission wheel 8, wherein the transmission wheel 8 is fixedly connected to one end of the driving shaft 5 located outside the processing table 1;

[0058] The second transmission wheel 15 is fixedly connected to one end of the transmission shaft 7 located outside the second fixed plate 6, and the first transmission wheel 8 and the second transmission wheel 15 are connected to each other through the second transmission member 29;

[0060] As the raw materials are conveyed, the driving shaft 5 drives the incomplete gear 9 to rotate, and the transmission wheel 1 8 also rotates accordingly. The transmission wheel 1 8 is connected to the transmission wheel 2 15 through the transmission member 2 29, which can further drive the transmission shaft 7 to rotate. The transmission shaft 7 then drives the cam 31 to rotate. Since the cam 31 and the roller 33 form a sliding fit, the connecting rod 32 can slide back and forth in the vertical direction. At this time, the elastic member 34 undergoes telescopic deformation, and the vertical reciprocating movement of the connecting rod 32 can drive the cutting knife 35 to complete the cutting process of the raw materials, and finally complete the cutting process of the mask belt.

[0061] See also Figure 1-Figure 2 In addition to the above technical solution, the utility model also provides another embodiment, which is different from the above embodiment in that a limiting plate 3 is provided on the top of the processing table 1, which can limit multiple raw materials to prevent the raw materials from being too loose during the cutting process.

[0062] The working principle of the utility model is:

[0063] In this embodiment, when it is necessary to cut the mask belt to equal length, the required raw material is inserted from one end of the processing table 1 between the feed roller 1 21 and the feed roller 2 30, and the threaded rod 14 in the middle of the fixed plate 4 is controlled to rotate by the control panel 12, and the threaded rod 14 then drives the transmission wheel 3 16 to rotate. Since the two transmission wheels 3 16 are connected by the transmission member 17, the two threaded rods 14 can be driven to rotate at the same time. Since the threaded fitting between the mounting frame 13 and the threaded rod 14, the rotation of the threaded rod 14 can make the mounting frame 13 rotate along the threaded rod 14 path vertical reciprocating slide, and in the process of the installation frame 13 sliding, the transmission gear three 24 and the guide rail 22 form a sliding fit, and finally the spacing between the feeding roller one 21 and the feeding roller two 30 is adjusted. After the spacing adjustment is completed, the control panel 12 is used to control the driving shaft 5 to rotate, and the driving shaft 5 then drives the incomplete gear 9 to rotate. Due to the meshing transmission between the incomplete gear 9 and the adjusting gear 11, the connecting shaft 10 can be further driven to rotate, and the connecting shaft 10 can then drive the transmission gear one 19 to rotate. The meshing transmission between the gears 20 can further drive the adjustment shaft 18 to rotate, and can make the transmission gear 3 24 and the transmission gear 2 20 rotate at the same time. Through the meshing transmission between the transmission gear 2 20 and the transmission gear 5 28, and the meshing transmission between the transmission gear 3 24 and the transmission gear 4 26, the installation shaft 1 25 and the installation shaft 2 27 can be rotated at the same speed in different directions, thereby driving the feed roller 1 21 and the feed roller 2 30 to rotate, completing the intermittent delivery of the raw materials of the mask belt. As the raw materials are delivered, the drive shaft 5 is moved in the belt. As the incomplete gear 9 rotates, the transmission wheel 1 8 also rotates accordingly, and the transmission wheel 1 8 is connected to the transmission wheel 2 15 through the transmission member 2 29, which can further drive the transmission shaft 7 to rotate, and the transmission shaft 7 then drives the cam 31 to rotate. Since the cam 31 and the roller 33 form a sliding fit, the connecting rod 32 can slide back and forth in the vertical direction. At this time, the elastic member 34 undergoes telescopic deformation, and the vertical reciprocating movement of the connecting rod 32 can drive the cutting knife 35 to complete the cutting process of the raw material, and finally complete the cutting process of the mask belt.
