Description

Technical Field

[0001] The present application relates to the technical field of medical device production equipment, and in particular to a sheet material folding device. Background Art

[0002] Patches, antipyretic patches, masks and other medical supplies are frequently used in people's daily lives and are often carried with them. In order to ensure the convenience of carrying and using such medical supplies, single-piece independent packaging is often used. At the same time, this packaging method also ensures that such medical supplies are cleaner and more hygienic during storage, transportation and carrying. On the other hand, the widespread use of independent packaging will generate a large amount of waste packaging, which will lead to waste of resources and environmental damage.

[0003] In order to reduce the generation of waste packaging, the sheet-like characteristics of bandages, fever patches and masks can be used to reduce their volume by folding them before packaging them independently, which can reduce the amount of packaging materials used and improve the convenience of carrying. For example, the Chinese invention patent with the authorization announcement number CN114084513B discloses an environmentally friendly and hygienic portable mask. By folding the mask before packaging, the size of the packaging bag is reduced, the amount of packaging materials used is reduced, the impact of packaging waste on the environment is reduced, and the convenience of carrying is improved.

Figure 1 ; Figure 2 The structure of the sheet material folding device provided in the embodiment of the present application is schematically shown. Figure 2 ; Figure 3 yes Figure 2 The enlarged schematic diagram of point A in the middle; Figure 4 It is a structural schematic diagram of a material input and conveying part in a sheet material folding device provided in an embodiment of the present application; Figure 5 The structure of the downward pressing transmission mechanism in the sheet material folding device provided in the embodiment of the present application is shown in FIG. Figure 1 ; Figure 6 The structure of the downward pressing transmission mechanism in the sheet material folding device provided in the embodiment of the present application is shown in FIG. Figure 2 .

[0063] See also Figure 1-Figure 6 As shown, an embodiment of the present application provides a sheet material folding device, including a material retention part and a material pressing part, wherein:

[0064] See also Figure 2 and Figure 3 As shown, the material retention portion is used to receive the sheet material 70 and guide the sheet material 70 to fold, and the material retention portion includes two guide plates 11, and the two guide plates 11 are arranged at an angle with respect to each other. The upper surface of the guide plate 11 has a guide slope, and the guide slopes of the two guide plates 11 are distributed in a V shape. A guide vertical surface is provided at the lowest point of the guide plate 11 near the guide slope, and a folding mouth 12 is formed between the guide vertical surfaces of the two guide plates 11, and a horizontal storage surface is provided at the highest point of the guide plate 11 near the guide slope.

[0065] See also Figure 2 and Figure 3 As shown, the material pressing part is used to apply a pressing force to the sheet material 70 on the material retention part, and the material pressing part is located above the material retention part.

[0066] Working process: The sheet material 70 to be folded is transported to the storage surface placed on the two guide plates 11, and then the downward pressing transmission mechanism is started. The downward pressing transmission mechanism drives the downward pressing top plate 21 to move downward. When the downward pressing top plate 21 moves downward to a certain extent, it will press on the sheet material 70 and bend the sheet material 70 downward. At this time, affected by the guide inclined surface, the sheet material 70 will tend to be bent into a V shape.

At this time, affected by the guide vertical surface, the two sides of the sheet material 70 will stand up with the downward pressing top as the center. At this time, the downward pressing transmission mechanism drives the downward pressing top plate 21 to move upward to leave the sheet material 70, thereby completing the folding of the sheet material 70.

When the sheet material 70 is placed on the storage surface of the guide plate 11, the correction telescopic device 51 drives the correction push plates 52 to move closer to each other, so that the sheet material 70 can be pushed to the top of the folding opening 12, and the folding opening 12 is aligned with the center line of the sheet material 70, so as to correct the position of the sheet material 70, which is conducive to folding the sheet material 70 in half.
