Description

Technical Field

[0001] The utility model belongs to the field of wet wipe processing equipment, and in particular relates to a wet wipe longitudinal folding mechanism for processing single wet wipes. Background Art

[0002] The processing of single-piece wet wipes mainly includes cutting, folding, bagging, adding liquid, packaging, etc. The folding process of wet wipes generally requires folding in half, but because the machine equipment runs too fast, the wet wipes may not be aligned during the folding process, resulting in folded corners, wrinkles, etc., which greatly affects subsequent operations. In addition, a type of single-piece wet wipe processing equipment can usually only process wet wipes of one size. If the wet wipes are too large or too small, different machines need to be switched to fold them in half. Therefore, how to solve the problem of rapid longitudinal folding and alignment of single-piece wet wipes and how to fold single-piece wet wipes of different sizes on the same machine during the production process has become the research topic of this utility model.

[0003] A Chinese patent with the authorization announcement number "CN214029520U" discloses a longitudinal folding mechanism for processing wet wipes, comprising a support plate, a first support leg fixedly connected to the top of the support plate, a slide rail base fixedly connected to the top of the first support leg, a slide rail provided inside the slide rail base, a sliding ball slidably connected inside the slide rail, a first folding plate fixedly connected to the outer wall of the sliding ball, a second folding plate movably hinged to one end of the first folding plate, a first groove provided inside the slide rail, a spring fixedly connected inside the first groove, and a ball bearing provided inside the first groove. Although the above patent solves the problem of longitudinal folding of wet wipes, the working efficiency is slow and it does not solve the problem of uneven alignment of wet wipes during the folding process and the problem of quickly folding wet wipes of different sizes.

[0004] In response to the above technical problems, this application proposes a solution. Utility Model Content

[0041] Those skilled in the art can use existing technologies they know, such as installing corresponding mechanical limit switches or photoelectric sensors to limit the specified positions of each actuator during the following action process; in order to achieve automated operation, the present invention can use CNC technology or PLC to control the actions of each actuator.

[0042] Device operation process:

[0043] like Figure 16 As shown, the longitudinal folding mechanism of the wet wipes of the single-piece wet wipes processing equipment is started, and the driving device 204 on the base 2 is started to drive the input roller 402 through the transmission device and then drive the input transmission device 403, and the cut wet wipes are spread flat on the input transmission device 403 and transmitted to the splint 104 on the rolling mechanism 1. The splint 104 is provided with an infrared detection device and a negative pressure device. The infrared detection device and the negative pressure device are existing technologies and are not described in detail. When the wet wipes are transmitted to the splint 104, the infrared detection device detects the specified position, that is, the position where the specific folding size is set, and the negative pressure device is started. The wet wipes are spread flat and firmly sucked on the splint 104, and the driving device 204 on the base 2 is started, rotating the roller 202, driving the rolling frame 101 to start rotating, because the multi-layer disc 110 is fixed relative to the rolling frame 101. Therefore, the second rotating connecting rod 114, fixed to the disc column of the multi-layer disc 110, simultaneously moves the two opposing clamping plates 104 on the rolling frame 101 toward each other, causing the clamping plates 104 to shift from their original horizontal position to an inwardly folded position. The wet wipes on the clamping plates 104 are now longitudinally folded, and the clamping plates 104 rotate and move to the position of the output mechanism 3 below. The transfer wheel 302 above the output mechanism 3 transfers the folded wet wipes to the output mechanism, completing the longitudinal folding of the wet wipes. The infrared detection device on the clamping plates 104 detects the wet wipes' movement and deactivates the negative pressure device. The clamping plates 104 begin to rotate upward. The first slide 111, which is coupled to the clamping plates 104, is pulled by the elastic device connected to the ends of the first slide rail 102, causing the first slide 111 to return to its original position. The second slide 108, pushed by the first rotating connecting rod 106, begins to push the clamping plates 104 to their initial position. The rolling frame 101 then drives the clamping plates 104 back to the position of the input mechanism 4 for the next longitudinal folding of the wet wipes.

[0044] The above process is for one set of wet wipes longitudinal folding mechanisms. This utility model has a total of four sets of wet wipes longitudinal folding mechanisms. When one set of wet wipes longitudinal folding mechanisms completes the previous step, the subsequent wet wipes longitudinal folding mechanisms will carry out the above steps in sequence. This improves the efficiency of wet wipes longitudinal folding more quickly.

[0045] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
