[0002] Currently, silicone is widely used in electronics, automotive industry, medical and daily life fields. To facilitate transportation, existing silicone raw materials are often made into rolls. To facilitate secondary processing and use, silicone raw materials need to be processed from rolls into granules. Therefore, it is necessary to cut the roll silicone raw materials into granules. However, existing silicone cutting equipment often only has the function of unidirectional cutting in the horizontal or vertical direction. After cutting, the strip silicone raw materials need to be cut again, which is cumbersome, inconvenient to use and has poor practicality.

[0003] In view of the existing related technologies, the existing silicone cutting equipment has the function of unidirectional cutting in the horizontal or vertical direction, which cannot meet the problem of bidirectional cutting, and no effective solution has been proposed.

The slitting transmission device is connected to the upper cutter via a transmission mechanism. The lower cutter is located at the lower end of the upper cutter, and a slitting flow channel is formed between the upper cutter and the lower cutter. The traction module conveys the long strip material to the slitting flow channel via the traction flow channel. The slitting drive device drives the slitting transmission device to rotate, thereby driving the upper cutter to press down, thus slitting the long strip material in the slitting flow channel. Through the differential speed between the second conveying assembly and the third conveying assembly, transversely separated granular material is formed, which finally flows out through the roll material conveying channel of the third conveying assembly.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See Figure 1-7 This application provides a sheet material brush treatment agent cutting machine, which includes a transverse cutting mechanism 100 and a longitudinal cutting mechanism 200. The transverse cutting mechanism 100 includes a first conveying component 11, a roll cutting and slitting component 12, and a slitting and stretching component 13. The longitudinal cutting mechanism 200 includes a second conveying component 21, a longitudinal cutting component 22, and a third conveying component 23. The longitudinal cutting component 22 is disposed between the second conveying component 21 and the third conveying component 23. The conveying speed of the third conveying component 23 is greater than the conveying speed of the second conveying component 21, forming a differential speed. The first conveying component 11 is used to convey the roll material... The material is conveyed to the slitting and rolling assembly 12; the slitting and rolling assembly 12 is used to cut the roll into long strips; the slitting and stretching assembly 13 is used to stretch the long strips longitudinally; the second conveying assembly 21 is used to receive the longitudinally stretched long strips and convey them to the slitting assembly 22 so that the long strips can be longitudinally cut into granules by the slitting assembly 22; the slitting assembly 22 is used to longitudinally cut the long strips into granules; the third conveying assembly 23 is used to receive the granules cut by the slitting assembly 22 and, based on the corresponding differential speed, to separate the front and rear rows of granules cut by the slitting assembly 22 at a preset transverse spacing.

[0029] It should be noted that this configuration integrates the transverse cutting mechanism 100 and the longitudinal cutting mechanism 200 into one unit, realizing the bidirectional cutting function of silicone roll material in both the transverse and longitudinal directions. Specifically, the transverse cutting mechanism 100 cuts the silicone roll material into long strips using the roller cutting and slitting component 12, and then uses the slitting and longitudinal pulling component 13 to longitudinally pull the long strips apart. At the same time, the longitudinal cutting mechanism 200 uses the second conveying component 21 to convey the independent long strips to the longitudinal cutting component 22, and the longitudinal cutting component 22 cuts the long strips into granules. Finally, the granules flow out through the third conveying component 23. The second conveying component 21 and the third conveying component 23 have a speed difference, thus pulling the granules apart laterally, thereby forming granules that are pulled apart both laterally and longitudinally. This results in high precision and cutting efficiency, smooth operation, no need for manual operation, and convenient packaging.

[0030] To achieve precise conveying of the silicone roll material, in some optional embodiments, the conveying speed of the first conveying assembly 11 is the same as that of the second conveying assembly 21, and the conveying speed of the third conveying assembly 23 is greater than that of the second conveying assembly 21. Each of the first, second, and third conveying assemblies includes a conveying module 24. The conveying module 24 includes a conveying support 241, a conveying drive device 242, a main conveying roller 243, a lifting and adjusting device 244, and a secondary conveying roller 245. The drive device 242, the main conveying roller 243, and the lifting adjustment device 244 are all mounted on the conveying support 241. The conveying drive device 242 is connected to the main conveying roller 243. The conveying slave roller 245 is raised and lowered above the main conveying roller 243 via the lifting adjustment device 244. A roll material conveying channel is formed between the main conveying roller 243 and the conveying slave roller 245. The conveying drive device 242 drives the main conveying roller 243, thereby driving the conveying slave roller 245 to roll, and thus driving the roll material to move within the roll material conveying channel.

[0031] It should be noted that with this configuration, the conveying drive device 242 uses a drive motor as its power source, which has high precision. At the same time, by using the lifting adjustment device 244 to adjust the distance between the main conveying roller 243 and the secondary conveying roller 245, it can adapt to silicone rolls of different thicknesses and specifications, further improving the conveying precision.

[0032] To achieve the cross-cutting function of silicone roll material, in some optional embodiments, the slitting assembly 12 includes a cross-cutting bracket 121, a cross-cutting drive device 122, a cross-cutting transmission device 123, a cross-cutting slitting circular blade 124, a circular blade adjusting device 125, and a cross-cutting conveying roller 126. The cross-cutting bracket 121 is located at the rear end of the conveying bracket 241 of the first conveying assembly 11. The cross-cutting drive device 122, the cross-cutting transmission device 123, the circular blade adjusting device 125, and the cross-cutting conveying roller 126 are all mounted on the cross-cutting bracket 121. The cross-cutting drive device 122 is connected to the cross-cutting slitting circular blade 124 via the cross-cutting transmission device 123. 24. The cross-cutting slitting circular blade 124 is adjustable in height between the cross-cutting support 121 and the circular blade adjustment device 125. The cross-cutting conveying roller 126 is located at the lower end of the cross-cutting slitting circular blade 124, and a cross-cutting flow channel is formed between the cross-cutting slitting circular blade 124 and the cross-cutting conveying roller 126. The first conveying component 11 conveys the roll material to the cross-cutting flow channel through the roll material conveying channel. The cross-cutting drive device 122 drives the cross-cutting transmission device 123 to rotate, thereby driving the cross-cutting slitting circular blade 124 and the cross-cutting conveying roller 126 to roll, thereby cross-cutting the roll material in the cross-cutting flow channel to form long strips.

[0033] It should be noted that with this configuration, the cross-cutting drive device 122 uses a drive motor as its power source, which has high precision. At the same time, by using the circular knife adjustment device 125 to adjust the distance between the cross-cutting slitting circular knife 124 and the cross-cutting conveying roller 126, the cross-cutting precision of the silicone roll material is further improved, so that the silicone roll material is cross-cut into long strips.

[0034] In order to achieve the purpose of longitudinally stretching the long strips, in some optional embodiments, the slitting and stretching assembly 13 includes a long strip separating device 131, which is located at the rear end of the transverse flow channel, and the lower end of the long strip separating device 131 is provided with a separating groove 132; wherein, after the long strips enter the long strip separating device 131, the long strips are longitudinally stretched by the separating groove 132 to form independent long strips.

[0035] It should be noted that with this configuration, the long strips are driven into the long strip separation device 131 by the conveying roller at the bottom. The separation trough 132 with intervals can restrict the conveying position of the long strips, so that the long strips can only pass through the separation trough 132, thereby pulling the long strips apart longitudinally to form independent and separated long strips.

[0036] To achieve the purpose of conveying long strips to the longitudinal component 22, in some optional embodiments, the second conveying component 21 further includes a detection device 25 and a traction module 26. The conveying module 24 of the second conveying component 21 is located at the rear end of the slitting and stretching component 13, the detection device 25 is located between the conveying module 24 and the traction module 26 of the second conveying component 21, and the traction module 26 is located at the front end of the longitudinal cutting component 22. In this case, the independent long strips flow sequentially through the conveying module 24, the detection device 25 and the traction module 26 of the second conveying component 21. The detection device is used to detect the presence or absence of long strips, and the traction module 26 is used to pull the longitudinally stretched long strips to the longitudinal cutting component 22.

[0037] To further achieve the purpose of conveying long strips of material to the longitudinal component 22, in some optional embodiments, the traction module 26 includes a traction bracket 261, a traction drive device 262, a traction main roller 263, and a traction slave roller 264. The traction bracket 261 is located at the front end of the longitudinal cutting component 22. The traction drive device 262, the traction main roller 263, and the traction slave roller 264 are all located on the traction bracket 261. The traction drive device 262 is connected to the traction main roller 263. The traction slave roller 264 is located at the upper end of the traction main roller 263, and a traction flow channel is formed between the traction main roller 263 and the traction slave roller 264. The traction drive device 262 drives the traction main roller 263 and the traction slave roller 264 to roll, thereby tractioning the long strip of material to the traction flow channel and conveying it to the longitudinal cutting component 22 through the traction flow channel.

[0038] It should be noted that with this setup, the conveying module 24 of the second conveying component 21 transports the independently separated long strips of material flowing out of the separation tank 132. After being detected by the detection device, the material is transported to the traction module 26. The traction drive device 262 of the traction module 26 uses a drive motor as its power source, which has high precision. At the same time, the traction main roller 263 and the traction slave roller 264 are used for transmission, so that the independently separated long strips of material accurately reach the longitudinal cutting component 22.

[0039] To achieve the function of longitudinal cutting of long strips, in some optional embodiments, the longitudinal cutting assembly 22 includes a longitudinal cutting bracket 221, a longitudinal cutting drive device 222, a longitudinal cutting transmission device 223, an upper cutter 224, and a lower cutter 225. The longitudinal cutting bracket 221 is disposed between the conveying bracket 241 of the second conveying assembly 21 and the conveying bracket 241 of the third conveying assembly 23. The longitudinal cutting drive device 222, the longitudinal cutting transmission device 223, the upper cutter 224, and the lower cutter 225 are all mounted on the longitudinal cutting bracket 221. The longitudinal cutting transmission device 223 is connected to the upper cutter 224 via the longitudinal cutting transmission device 223. The transmission connection is such that the lower cutter 225 is located at the lower end of the upper cutter 224, and a longitudinal cutting flow channel is formed between the upper cutter 224 and the lower cutter 225. The traction module 26 transports the long strip material to the longitudinal cutting flow channel through the traction flow channel. The longitudinal cutting drive device 222 drives the longitudinal cutting transmission device 223 to rotate, thereby driving the upper cutter 224 to press down, thereby longitudinally cutting the long strip material in the longitudinal cutting flow channel. Through the differential speed between the second conveying component 21 and the third conveying component 23, the material is divided into transversely separated granules, which finally flow out through the roll material conveying channel of the third conveying component 23.

[0040] It should be noted that with this configuration, the longitudinal cutting drive device 222 drives the upper cutter 224 to move up and down through the longitudinal cutting transmission device 223, so that the upper cutter 224 and the lower cutter 225 cooperate to longitudinally cut the long strip material flowing through the channel. At the same time, there is a speed difference between the second conveying component 21 and the third conveying component 23. The conveying speed of the third conveying component 23 is greater than the conveying speed of the second conveying component 21. Therefore, the granules on the third conveying component 23 move faster, and the front and rear granules are laterally pulled apart, creating a lateral gap between the front and rear granules.

[0041] To achieve the function of unwinding and rewinding the roll material, some optional embodiments further include a roll unwinding assembly, a roll release film winding assembly, and a cross-cutting waste material winding assembly. The roll release film winding assembly includes an upper roll release film winding assembly and a lower roll release film winding assembly. The roll unwinding assembly is used to convey the roll material to the first conveying assembly 11 and then to the slitting assembly 12 via the first conveying assembly 11. The upper roll release film winding assembly is used to wind up the upper release film on the roll material, the lower roll release film winding assembly is used to wind up the lower release film on the roll material, and the cross-cutting waste material winding assembly is used to wind up the waste material generated after the slitting assembly 12 cuts the roll material.

[0042] To further realize the function of unwinding and rewinding the roll material, some optional embodiments also include a support film unwinding assembly and a support film release film winding assembly. The support film release film winding assembly includes an upper support film release film winding assembly and a lower support film release film winding assembly. The support film unwinding assembly is used to support and feed the long strip material. The upper support film release film winding assembly is used to wind up the upper release film of the support film. The lower support film release film winding assembly is used to wind up the lower release film of the support film.

[0043] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
