Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mask preparation, in particular to a feeding device used for making masks. Background Art
[0002] With the frequent occurrence of global public health events, the demand for masks as personal protective equipment has increased significantly. Traditional mask production methods are mostly manual or semi-automatic, with low production efficiency and difficulty in meeting the needs of large-scale production. Therefore, the development of efficient and automated mask production equipment has become an important trend in the development of the industry.
[0003] In the delicate process of making masks, the feeding equipment plays a vital role. The main responsibility of this equipment is to ensure that the raw materials of the masks can be accurately transferred to the subsequent processing links in the established proportions and sequence, thereby ensuring the continuity and efficiency of mask production.
[0004] At present, in the process of producing masks, multiple sets of rollers are generally used to accurately limit the position of the fabric and stably convey it. The original intention of the design of the roller is to smoothly convey the fabric from one link to another through its rolling action. However, in actual operation, this conveying method is not perfect. It is inevitable that there will be a certain amount of friction between the roller and the fabric, and the friction between multiple sets of rollers and the fabric is often different. This difference in friction will cause the tension of the fabric between the two sets of rollers to change. Once the tension is unbalanced, the fabric will easily loosen.
[0005] The loose fabrics piled up between the rollers not only seriously affect the normal conveying of the fabrics, resulting in reduced production efficiency, but also may cause damage to the fabrics themselves. These damages may manifest as wear, stretching, deformation or even tearing of the fabrics, which is undoubtedly fatal for products such as masks that have extremely high material requirements.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-3 The utility model provides a technical solution for feeding equipment for making masks:
[0023] according to Figure 1-2As shown, the feeding equipment for making masks includes a reel 1, on which a rolled cloth 2 is rolled, the cloth 2 passes through an operating box 3, and slides through a first pressing roller 4, an adjusting pressure roller 6 and a second pressing roller 7 in sequence, support columns 19 are fixedly connected around the bottom of the operating box 3, there are two first pressing rollers 4 and two second pressing rollers 7, each forming a group, tangent to each other up and down, and both are slidably assembled inside the operating box 3, wherein the first pressing roller 4 is connected to a first motor 5, the second pressing roller 7 is connected to a second motor 8, the left and right ends of the adjusting pressure roller 6 are rotatably connected to a piston box 20, and a pressure plate 9 is correspondingly installed directly below, and the pressure plate 9 can pass through a through slot opened at the bottom of the operating box 3, a lower pull-down frame 11 is fixedly connected to the middle of the bottom, and the bottom A plurality of first springs 10 are evenly fixed on the left and right sides of the part, a pull-down frame 11 passes through a support plate 12 and a connecting rod 13 is fixed on the other end, the bottom of the first spring 10 is fixed on the support plate 12, the support plate 12 is fixed on the bottom of the operating box 3, racks 16 are fixed on the left and right ends of the connecting rod 13, gears 17 are installed on the sides of the racks 16, the gears 17 are sleeved and fixed on the left and right ends of the reel 1, and the left and right ends of the reel 1 are rotatably installed on the limit frames 18; two-thirds of the racks 16 are equipped with teeth required for meshing, and one-third are not equipped with teeth, which is a smooth surface; a plurality of telescopic rods 14 are evenly fixed on the bottom of the right side of the pull-down frame 11, and the outer walls of the plurality of telescopic rods 14 are sleeved with second springs 15, and the upper ends of the second springs 15 are fixed to the bottom of the pull-down frame 11.
[0024] When in use, the cloth 2 passes between the first nip roller 4 and the second nip roller 7, and the nip rollers are driven to rotate by the first motor 5 and the second motor 8 respectively, so as to realize the transmission of the cloth 2. Due to the different friction between the cloth 2 and different nip rollers, when the friction of the first nip roller 4 is too small, the cloth 2 will be accumulated in the operation box 3. At this time, the pressure roller 6 is adjusted to no longer resist the cloth 2, and it will fall to the bottom of the operation box 3 and hit the pressure plate 9. The pressure plate 9 is pressed down by the impact force, and the lower pull frame 11 is driven to move downward quickly at the same time, and the rack 16 is quickly pulled downward by the connecting rod 13, so that the teeth on the upper half of the rack 16 are meshed with the gear 17, so that the gear 17 drives the reel 1 to rotate clockwise, and the cloth 2 is normally In this case, it rotates counterclockwise and continuously transports. When the reel 1 rotates counterclockwise, the cloth 2 is reeled back to recycle the loose and accumulated cloth 2, so that the cloth 2 generates tension again between the first pressing roller 4 and the second pressing roller, and the flattened cloth 2 pushes up the adjusting pressure roller 6. At this time, the pressure plate 9 is reset upward under the action of the first spring 10, and the lower pull-up frame 11 moves upward at the same time with the help of the telescopic rod 14 and the second spring 15, which drives the connecting rod 13 and the rack 16 to move upward at the same time. When the rack 16 moves upward to the smooth part, the gear 17 no longer meshes with the rack 16. At this time, the reel 1 drives the cloth 2 to resume counterclockwise transportation again. The device can reset the accumulated cloth 2 to ensure stable transportation of the cloth 2.
