Description

Technical Field

[0001] The present application relates to the technical field of mask production equipment, and in particular to a one-to-one high-speed mask sheeting machine. Background Art

[0002] Existing flat masks are mainly produced by two processes: mask sheet forming and ear strap welding. The mask sheet forming is completed by a mask sheet punching machine, and the ear strap welding is completed by an automatic mask ear strap welding machine. The welding machine and the sheet punching machine are connected by a connecting device. According to the number of sheet punching machines connected to the welding machines, it can be divided into one-to-one or one-to-multiple.

[0003] In related art, Chinese patent publication number CN214779689U proposes a high-speed mask sheeting machine, which includes a mounting frame and a slicing module fixed to the mounting frame. The mounting frame is provided with a feeding module, which includes multiple correction rollers. The arrangement direction of the multiple correction rollers is consistent with the arrangement direction of the feeding module and the slicing module. The correction rollers are rotatably connected to the mounting frame and use a power source as a power mechanism. The two ends of the correction rollers are frustum structures, and the large ends of the two frustums are far away from each other. This application has the effect of reducing the possibility of fabric deviation.

[0004] Regarding the above-mentioned related technologies, the correction roller is moved so that the cone structures at both ends of the correction roller exert force on the side of the fabric that is offset, so that the fabric can slide along the inclined surfaces of the cones at both ends of the correction roller toward the middle of the correction roller, thereby achieving the effect of correcting the fabric offset; however, in reality, the fabric of the mask is extremely soft, and the effect of correcting the deviation is not significant only by applying external force to the side of the fabric. Utility Model Content

[0005] In order to improve the problem of soft fabrics being offset during transmission, the present application provides a one-to-one high-speed mask sheeting machine.

[0006] The one-to-one high-speed mask sheeting machine provided in this application adopts the following technical solutions:

[0007] A one-to-one high-speed mask sheeting machine includes a mounting frame, a slicing module and a feeding module arranged on the mounting frame. A deflection correction platform is fixedly connected to the middle of the mounting frame table, and the deflection correction platform is arranged between the slicing module and the feeding module. The width of the deflection correction platform gradually increases along the fabric transmission direction. The side of the deflection correction platform is provided with an inwardly concave arc surface. Two deflection correction wheels are lifted and lowered on the mounting frame. The two deflection correction wheels are arranged in a one-to-one correspondence with the two inwardly concave arc surfaces, and the deflection correction wheels are fitted with the inwardly concave arc surfaces.

[0008] Furthermore, the outer circumference of the correcting wheel is set to be an outward convex arc surface, and the outer diameter of the correcting wheel near the middle of the mounting frame is smaller than the outer diameter near the side of the mounting frame.

[0009] Furthermore, an anti-skid layer is fixedly connected to the outer peripheral surface of the correcting wheel and / or the inner concave arc surface or an anti-skid structure is provided.

[0010] Furthermore, the mounting frame is provided with a detection mechanism for monitoring the deviation of the cloth and a driving component for driving the deviation-correcting wheel to rise and fall, and the detection mechanism is control-connected to the driving component.

[0011] Furthermore, the detection mechanism includes two distance sensors installed on both sides of the mounting frame, and the detection heads of the distance sensors point to the outside of the edge of the fabric; the driving assembly includes two linear driving components installed on the mounting frame, the correcting wheel is installed on the output end of the linear driving component, and the distance sensor is controlled and connected to the linear driving component located on the other side of the correcting platform.

[0012] Furthermore, the mounting frame is rotatably mounted with a flattening roller pressed against the cloth between the deflection correction platform and the slicing module.

[0013] Furthermore, at least two flattening rollers are arranged on both sides of the mounting frame, and the two oppositely arranged flattening rollers are arranged in an "eight" shape, and the closing ends of the two flattening rollers face the direction of fabric transmission.

[0014] To sum up, the beneficial technical effect of the present application is: when it is found that the cloth is deviated to one side, for example, when the cloth is deviated to the left side in the cloth transmission direction, the correction wheel located on the right side of the cloth transmission direction is driven to descend until it contacts the concave arc surface on the right side of the correction table. At this time, the cloth passes through the gap between the correction wheel and the concave arc surface on the correction table, and under the guiding action of the two, the cloth is corrected as a whole in the direction closer to the right until the cloth transmission returns to normal, the correction wheel is lifted, and the correction process is completed; and because the traction part of the correction wheel and the correction table on the cloth is located in the middle of the cloth width direction, even if the cloth is extremely soft, good correction can be performed.

[0018] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0019] The embodiment of the present application discloses a one-to-one high-speed mask sheeting machine. Figure 1 and Figure 2 The one-to-one high-speed mask sheeting machine includes a mounting frame 1, a slicing module 2 and a feeding module 3 mounted on the mounting frame 1. A deflection correction platform 4 is fixedly connected to the middle of the mounting frame 1 surface. The deflection correction platform 4 is arranged between the slicing module 2 and the feeding module 3 and is arranged along the transmission direction of the fabric. The width of the deflection correction platform 4 gradually increases along the transmission direction of the fabric, and the side of the deflection correction platform 4 is provided with an inward concave arc surface 41. Two deflection correction wheels 5 are arranged on the mounting frame 1 for lifting and lowering. The two deflection correction wheels 5 are arranged in a one-to-one correspondence with the two inward concave arc surfaces 41, and the deflection correction wheels 5 are fitted with the inward concave arc surfaces 41. More specifically, the outer circumference of the deflection correction wheel 5 is set as an outward convex arc surface, and the outer diameter of the deflection correction wheel 5 near the middle of the mounting frame 1 is smaller than its outer diameter near the side of the mounting frame 1.

[0020] With this arrangement, when the feeding module 3 finds that the fabric is deviating to one side, such as to the left of the fabric transmission direction, during the process of conveying the fabric to the slicing module 2, the deflection correction wheel 5 located on the right side of the fabric transmission direction is driven down until it contacts the right side concave arc surface 41 of the deflection correction platform 4. At this time, the fabric passes through the gap between the deflection correction wheel 5 and the concave arc surface 41 of the deflection correction platform 4. Under the guidance of the deflection correction wheel 5 and the concave arc surface 41 of the deflection correction platform 4, the fabric is corrected to the right side as a whole until the fabric transmission returns to normal and the deflection correction wheel 5 is raised. Similarly, when the fabric deviates to the right, the deflection correction wheel 5 on the left side is lowered and pulls the fabric to correct it, thereby achieving the effective deflection correction effect of the present application. Moreover, because the traction portion of the deflection correction wheel 5 and the deflection correction platform 4 on the fabric is located in the middle of the fabric width direction, even extremely soft fabric can be effectively corrected.

[0021] In order to further improve the pulling effect of the correcting wheel 5 and the correcting platform 4 on the cloth, refer to Figure 1 and Figure 2 An anti-slip layer 51 or an anti-slip structure is fixedly attached to the outer circumference of the correcting wheel 5 and / or the inner concave arc surface 41. The anti-slip layer 51 is made of a rubber with a high static friction coefficient, such as silicone rubber or fluororubber. The anti-slip structure comprises anti-slip protrusions evenly distributed on the correcting wheel 5 and the inner concave arc surface 41. The multiple anti-slip protrusions on the correcting wheel 5 and the multiple anti-slip protrusions on the inner concave arc surface 41 are arranged in a staggered manner.

[0022] This can significantly increase the resistance of the cloth passing through the deflection correction wheel 5 and the deflection correction platform 4, thereby improving the traction effect of the deflection correction wheel 5 and the deflection correction platform 4 on the cloth, and further improving the deflection correction efficiency.

[0023] Considering the fast speed of fabric transmission, it is difficult to adapt to manual operation. Figure 1 and Figure 2 Therefore, a detection mechanism for monitoring the deviation of the fabric and a drive assembly for driving the correction wheel 5 to rise and fall are provided on the mounting frame 1. The detection mechanism is control-connected to the drive assembly. Specifically, the detection mechanism includes two distance sensors 6 installed on both sides of the mounting frame 1. The detection heads of the distance sensors 6 point to the outside of the fabric edge. The drive assembly includes two linear drive members 7 installed on the mounting frame 1. The correction wheel 5 is installed on the output end of the linear drive member 7. The distance sensor 6 is control-connected to the linear drive member 7 located on the other side of the correction platform 4. The linear drive member 7 can be an air cylinder, an oil cylinder, an electric push rod, a linear motor, etc. In this embodiment, the linear drive member 7 is set to a cost-effective air cylinder. In addition, the distance sensor 6 should be set on the side of the correction platform 4 close to the slicing module 2.

[0024] After such arrangement, when the cloth deviates to one side, it is detected by the distance sensor 6 on that side, and then the linear drive member 7 on the opposite side is controlled to move downward so that the correction wheel 5 on it is pressed against the concave arc surface 41 of the correction platform 4 away from the side of the distance sensor 6, so as to realize automatic correction of the deviated cloth; when the cloth after correction is transmitted between the two distance sensors 6 and the transmission path is detected to be normal, the linear drive member 7 drives the correction wheel 5 to lift to complete the correction action.

[0025] After the fabric is corrected, it will have a certain degree of wrinkles when passing between the correcting wheel 5 and the correcting platform 4. In order not to affect the subsequent smooth transmission of the fabric, Figure 1 and Figure 2 The mounting frame 1 is rotatably installed between the correction platform 4 and the slicing module 2 with a flattening roller 8 pressed against the cloth. Specifically, at least two flattening rollers 8 are arranged on both sides of the mounting frame 1. In this embodiment, two flattening rollers 8 are arranged and the two oppositely arranged flattening rollers 8 are arranged in an "eight" shape, and the closing ends of the two flattening rollers 8 face the direction of cloth transmission.

[0026] In this way, the fabric corrected by the correction wheel 5 and the correction table 4 is flattened and guided to the side by the two flattening rollers 8 and laid flat on the table of the mounting frame 1, and is transmitted to the slicing module 2, which can effectively ensure the accuracy and flatness of the fabric corrected by this application during transmission.

[0027] The implementation principle of the one-to-one high-speed mask sheeting machine of the embodiment of the present application is as follows: when the feeding module 3 is conveying the cloth to the slicing module 2, when it is found that the cloth is deflected to one side, for example, when the cloth is deflected to the left side of the cloth transmission direction, the correcting wheel 5 located on the right side of the cloth transmission direction is driven to descend until it contacts the concave arc surface 41 on the right side of the correcting platform 4. At this time, the cloth passes through the gap between the correcting wheel 5 and the concave arc surface 41 on the correcting platform 4, and under the guidance of the two, the cloth is corrected in the direction close to the right until the cloth transmission returns to normal and the correcting wheel 5 is raised; similarly, when the cloth deflects to the right, the correcting wheel 5 on the left descends and pulls the cloth to correct it, thereby achieving the effective correction effect of the present application on the cloth. And because the traction part of the correcting wheel 5 and the correcting platform 4 on the cloth is located in the middle of the cloth width direction, even if the cloth is extremely soft, good correction can be performed.

[0028] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
