These steps together ensure that the masks have the necessary filtering and protection functions. To achieve this production process, the raw materials of the masks must be accurately fed into the manufacturing equipment. Therefore, the feeding device for mask raw materials plays a key role in this process. This device is responsible for automatically loading and transporting the various layers of materials required for the mask body, ensuring the continuity of production and the quality of the masks.

[0003] After retrieval, for example, the utility model patent of CN213912806U discloses a raw material conveying device for mask processing, including a feeding box.

One side of the lower part inside the feeding box is provided with a first feeding roller, and the other side of the lower part inside the feeding box is provided with a third feeding roller. A second feeding roller is arranged between the first feeding roller and the third feeding roller. The first feeding roller, the second feeding roller, and the third feeding roller are all rotatably connected to one side wall of the feeding box. An outlet is opened on one end wall of the feeding box close to the support seat. For this raw material conveying device for mask processing, through the combined action of three feeding rollers and three positioning rollers, the masks can be fed in layers, and the mask materials can be stably conveyed. The power motor drives the power roller to rotate, so that the combined mask raw materials are transported and operated, which is beneficial to the automatic conveying of the masks.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , the mask raw material feeding device in this embodiment includes a housing 1, three feeding rollers 2 and three guide rollers 3 are rotatably installed inside the housing 1, a fixed seat 4 is fixedly installed on the right side of the housing 1, and a conveying assembly 5 is arranged on the top of the fixed seat 4.

[0023] The conveying assembly 5 includes a mounting plate 501, the mounting plate 501 is fixedly installed on the top of the fixed seat 4, the bottom of the front side of the mounting plate 501 is fixedly installed with a bottom plate 502, the top of the front side of the mounting plate 501 is fixedly installed with a top plate 503, the bottom plate 502 is fixedly installed with a first concave frame 504 on the top, the front side of the first concave frame 504 is fixedly installed with a motor 505, the output shaft of the motor 505 is fixedly installed with a driving roller 506, the front side of the mounting plate 501 is movably installed with a movable plate 507, the bottom of the movable plate 507 is fixedly installed with a second concave frame 508, a driven roller 509 is rotatably installed between the front and rear inner walls of the second concave frame 508, and an adjusting mechanism 6 is arranged on the top of the movable plate 507.

[0024] An opening is provided on the right side of the housing 1, and three kinds of mask raw materials respectively pass through the opening from the feeding rollers 2, pass through the corresponding guide rollers 3, and are drawn between the driving roller 506 and the driven roller 509 for combined conveying.

[0025] The driving roller 506 is located in the forward direction of the driven roller 509. One end of the driving roller 506 away from the motor 505 is rotatably connected to the rear inner wall of the first concave frame 504. The driving roller 506 can rotate on the first concave frame 504, and the driven roller 509 can rotate on the second concave frame 508. By operating the motor 505, the driving roller 506 and the driven roller 509 can rotate to realize the conveying of raw materials.

[0026] The adjusting mechanism 6 includes an adjusting rod 601. The adjusting rod 601 is rotatably installed in the middle of the top of the movable plate 507. Slide rods 602 are fixedly installed at both ends of the top of the movable plate 507. Springs 603 are sleeved on the outer surfaces of the two slide rods 602.

[0027] The adjusting rod 601 is threadedly connected to the top plate 503. The two slide rods 602 are both slidably connected to the top plate 503, and limit pieces are fixedly installed at the tops of the two slide rods 602.

[0028] By rotating the adjusting rod 601, the movable plate 507 can move up and down under the action of the two slide rods 602, so as to adjust the distance between the driven roller 509 and the driving roller 506. The driven roller 509 is adjusted to a suitable position according to the different thicknesses of the mask raw materials to meet the conveying requirements of different masks.

[0029] The two springs 603 are both fixedly installed between the bottom of the top plate 503 and the top of the movable plate 507, and the springs 603 play a buffering role.

[0030] A pointer 604 is fixedly installed on the right side of the movable plate 507. A marking scale 605 adjacent to the pointer 604 is fixedly installed at the right end of the front side of the mounting plate 501. A long strip magnifying glass 606 is fixedly installed on the front side of the marking scale 605.

[0031] When the movable plate 507 moves up and down, it will drive the pointer 604 to move up and down. The pointer 604 points to the specified mark on the marking scale 605 to realize the precise adjustment of the position of the driven roller 509. Since the difference in mask thickness is in microns, the scale on the marking scale 605 can be magnified by the long strip magnifying glass 606, making it clearer to observe.

[0032] During implementation, the operations are carried out in the following steps:

[0033] 1) First, one end of the mask raw material is respectively pulled by the feeding roller 2 and the guiding roller 3 to the space between the driving roller 506 and the driven roller 509;

[0034] 2) Then, according to the different thicknesses of the mask raw materials, the height of the driven roller 509 is adjusted. During adjustment, first rotate the adjusting rod 601 to drive the movable plate 507 to move up and down, and the movable plate 507 drives the two slide rods 602 to slide in the top plate 503;

[0035] 3) The movable plate 507 drives the driven roller 509 to move up and down until the driven roller 509 is adjusted to a suitable height, where the top of the mask raw material contacts the driven roller 509 and the bottom contacts the driving roller 506.

[0036] 4) Finally, the driving roller 506 is driven to rotate by the motor 505 to convey the mask raw material.

[0037] In summary, for the mask raw material feeding device, by setting the conveying assembly 5, the mask raw materials on the three feeding rollers 2 can be combined and conveyed. Under the action of the adjusting mechanism 6, the height of the driven roller 509 can be adjusted, so that the distance between the driving roller 506 and the driven roller 509 can be adjusted. The driven roller 509 is adjusted to a suitable position according to the different thicknesses of the mask materials to meet the conveying of mask raw materials with different thicknesses.

[0038] Furthermore, by setting the pointer 604 and the marking scale 605, the accuracy of adjusting the driven roller 509 is improved, and the operator can more easily find the correct position of the driven roller 509. At the same time, the use of the long strip magnifier 606 makes the observation clearer.
