In this way, the second air hole 105, the third air hole 106 and the first air hole 104 are respectively arranged at the eye position, the mouth position and the forehead or chin position of the mask corresponding to the knife roller 1, the second air hole 105, the third air hole 106 and the first air hole 104 are respectively communicated with the second air passage 108, the third air passage 109 and the first air passage 107, when the knife roller 1 rotates relative to the end cover 2, the second air passage 108 and the third air passage 109 can be sequentially communicated with the air extraction opening and the air blowing opening 203 on the end cover 2, the time and the state that the air extraction opening and the air blowing opening 203 are communicated by the second air passage 108 and the third air passage 109 can be controlled by reasonably setting the length of the air extraction opening and the air blowing opening 203, so that waste is always adsorbed on the knife roller 1 at a set position or angle and blown off at another set position, thereby realizing fixed-point discharge of the waste, being beneficial to improving the production quality and prolonging the service life of equipment and improving the production efficiency. The first air hole 104 can be communicated with the air extraction opening, so that the mask is adsorbed on the knife roller 1 when the front roller cuts the forehead or chin of the mask, the problem that the mask is attached to the bottom roller 3 can be avoided, and the practicability is high.
In order to realize the installation of the end cover 2, as shown in fig. 1, two ends of the knife roller 1 are provided with installation shafts, a shaft shoulder 110 is arranged on the installation shafts, the end cover 2 is sleeved on the shaft shoulder 110, and a bearing is arranged between the end cover 2 and the shaft shoulder 110, so that the knife roller 1 can rotate relative to the end cover 2.

The teflon coating is a material and wear-resistant measure which are known in the market and have wide application range, and the comprehensive indexes of the purchase cost, the processing cost and the use effect of the teflon coating are optimal.
Because the waste materials at the eyes and mouth of the mask are required to be discharged at fixed points, the mask is only required to be cut at the initial position of the roller without being adhered to the bottom roller 3, and in order to simplify the structure, the embodiment preferably adopts a structural design that the first air passage 107 is communicated with the air extraction opening, and the second air passage 108 and the third air passage 109 are sequentially communicated with the air extraction opening and the air inlet.
As shown in fig. 3, in this embodiment, the exposed ends of the second air passage 108 and the third air passage 109 at the end of the cutter roller 1 are distributed on the same circumference, and the exposed ends of the first air passage 107 at the end of the cutter roller 1 and the exposed ends of the second air passage 108 and the third air passage 109 are located on different circumferences. And the first air passage 107, the second air passage 108 and the third air passage 109 are all straight-line passage structures which are parallel to the axis of the knife roller 1 and penetrate through the knife roller 1 so as to facilitate processing. End caps 2 are symmetrically arranged at two ends of the knife roller 1. As shown in fig. 4 and 5, the pumping port includes a first arc-shaped air port 201 disposed on the same circumference as the exposed end of the first air passage 107, and a second arc-shaped air port 202 disposed on the same circumference as the exposed end of the second air passage 108, and the third air passage 109, one ends of the first arc-shaped air port 201 and the second arc-shaped air port 202 are flush, and the air blowing port 203 has an arc-shaped opening structure disposed on the same circumference as the exposed end of the second air passage 108, and the third air passage 109. Thus, during the rotation of the cutter roller 1, the first air passage 107 can communicate with the first arc-shaped air port 201 in a set rotation angle range to realize suction, and the second air passage 108 and the third air passage 109 can communicate with the second arc-shaped air port 202 and the air blowing port 203 respectively to realize suction and blowing. Wherein the interval or arc length between the second arc-shaped air port 202 and the air blowing port 203 can be flexibly set according to the needs.
Further, the first arc-shaped air port 201 and the second arc-shaped air port 202 are connected with a vacuum suction device, and the air blowing port 203 is connected with an air supply device. The first arc-shaped air port 201 and the second arc-shaped air port 202 are connected with the end part of the vacuum suction device, and the air blowing port 203 is connected with the end part of the air blowing device, and the end part is exposed out of the side surface of the end cover 2 or the end surface facing away from the knife roller 1. As shown in the figure, a bottom roller 3 is disposed below the knife roller 1, and the bottom roller 3 performs face-film roll cutting processing in cooperation with the knife roller 1. The ends are then preferably arranged on the upper side, front side, rear side of the end cap 2 and on the side wall facing away from the knife roller 1, in order to interface the vacuum suction means and the air supply means.
Further, the air extraction opening is arranged on one side of the end cover 2, which is close to the bottom roller 3. The flush ends of the first arc-shaped air port 201 and the second arc-shaped air port 202 are close to the bottom roller 3, and the flush ends of the first arc-shaped air port 201 and the second arc-shaped air port 202 are preferably collinear with the contact ends of the bottom roller 3 and the knife roller 1, so that the mask and the corresponding waste roller are adsorbed at the initial position of cutting and forming, the mask is prevented from being attached to the bottom roller 3, and waste is prevented from falling off from the mask. Because the mask only needs to overcome the adsorption effect of the bottom roller 3 when the initial position of the roller cutting (the position of the first cutting edge 101 is firstly selected between the knife roller 1 and the bottom roller 3), the central angle corresponding to the first arc-shaped air port 201 is 5-30 degrees, preferably 12 degrees, so that the front end of the mask can be adsorbed through the first air hole 104 when the roller cutting initial position of the mask, the mask is prevented from being attached to the bottom roller 3, and when the rotation angle exceeds 12 degrees, the adsorption force of the first air hole 104 disappears, and the mask falls back on a conveying device for conveying the mask under the action of gravity. The waste materials need to be discharged and collected at fixed points, and considering that other devices are arranged at the input end and the output end of the cutter roller 1 when the waste materials are applied to the assembly line operation, in this embodiment, the air blowing port 203 is arranged on one side of the end cover 2 away from the bottom roller 3, so that the second air hole 105 and the third air hole 106 are communicated with the air blowing port 203 and blow the waste materials when rotating upwards. Further, the second air hole 105 and the third air hole 106 need to rotate at least 90 ° from the contact end of the knife roll 1 and the bottom roll 3 to avoid the waste falling in the state of being connected to the second arc-shaped air port 202 for adsorption, so the central angle corresponding to the second arc-shaped air port 202 is 90 ° -150 °, preferably 120 °. And the central angle of the air blowing port 203 is 5-35 degrees, preferably 15 degrees, so as to ensure that the waste materials are completely blown out. When the second air passage 108 and the third air passage 109 rotate between the second arc-shaped air passage 202 and the air blowing opening 203, the second air passage 108 and the third air passage 109 rotate 90 degrees, that is, the second air hole 105 and the third air hole 106 face upwards, and the waste materials are naturally attached to the knife roller 1 under the action of gravity, so that the waste materials still cannot fall off even though the second air passage 108 and the third air passage 109 are not communicated with the second arc-shaped air passage 202. The knife roller 1 and the end cover 2 with the structure are matched, the fixed-point discharge of waste materials and the anti-sticking function of the bottom roller 3 can be realized, and the structure is compact and simple, the assembly is convenient, and the practicability is strong.
Further, the knife roll 1 is provided with a plurality of rings of bosses 111, and the bottom roll 3 is abutted by the bosses 111. The first cutting edge 101, the second cutting edge 102 and the third cutting edge 103 are higher than the boss 1110.01mm plus or minus 0.01mm, so that the roll cutting quality is ensured. And in order to ensure that the rotation speeds of the knife roller 1 and the bottom roller 3 are consistent, one end or two ends of the knife roller 1 are provided with a first transmission gear 112 which is coaxial with the knife roller 1, one end or two ends of the bottom roller 3 are provided with a second transmission gear 301 which is coaxial with the bottom roller 3 corresponding to the first transmission gear 112, and the first transmission gear 112 and the second transmission gear 301 are meshed with each other to realize synchronous rotation of the knife roller 1 and the bottom roller 3. Meanwhile, the first transmission gear 112 and the second transmission gear 301 have the same size to maintain the same rotation speed. And the outer diameter of the boss 111 is the same as the diameter of the bottom roller 3 to realize the same-speed rotation. Therefore, the friction force of the upper surface and the lower surface of the mask can be balanced, and the quality of the mask can be improved.
In addition, in order to achieve the cooperation of the cutter roller 1 and the bottom roller 3, as shown in fig. 6, the cutter roller 1 and the bottom roller 3 are rotatably mounted on a frame 4, the end cover 2 is relatively fixed with the frame 4 so that the end cover 2 is not rotatable, and an elastic crimping device is arranged on the frame 4 at the upper end of the cutter roller 1, so as to be used for keeping the cutter roller 1 and the bottom roller 3 in cooperation, and simultaneously avoid excessive wear of the first cutting edge 101, the second cutting edge 102 and the third cutting edge 103. The elastic crimping device can be of a spring structure, and also can be of an air cylinder or hydraulic cylinder structure. The vacuum waste discharge device 5 is arranged above the frame 4, and the vacuum waste discharge device 5 is arranged corresponding to the first blade 101, so that when the second air passage 108 and the third air passage 109 are communicated with the air blowing port 203, the second blade 102 and the third blade 103 are abutted, and the waste is directly collected by the vacuum waste discharge device 5 while being blown out. And dust generated during the roll cutting process and adhered to the blade or the knife roll 1 can be removed by the vacuum waste discharging device 5, so that the practicability is high.
The above examples are only preferred embodiments of the application, and other embodiments of the application are possible. Equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the application, and these equivalent modifications or substitutions are intended to be included within the scope of the present application as set forth in the following claims.
