[0002] At present, wet wipes are a typical product that has successfully transformed from a conceptual product to a regular daily necessity in recent years. They usually use wet-strength paper or non-woven fabric as raw materials, add functional liquid to make it saturated, and then package it in a sealed bag to form the final use form. Wet wipes are a common skin care product in daily life. Generally, wet wipes are packaged in plastic film, and a wet wipe cover is connected to the package with glue to increase the sealing and protection, and prevent the wet wipes from being contaminated or drying out.

[0003] Most of the existing lidding machines use robots to apply lids, and in order to avoid the failure of lidding due to the deviation of the packaging bag position, a set of calibration robots is often added. However, although the use of robots to calibrate the packaging bag can solve the calibration problem, the cost increases sharply, and maintenance requires special personnel, which is not conducive to the development of small and medium-sized enterprises.

[0004] To this end, we proposed a capping machine with a calibration function. Through innovative mechanical design and calibration technology, we can achieve the position calibration of the wet wipes box in the iron cover, while reducing equipment costs and maintenance difficulties, and improving the competitiveness and production efficiency of small and medium-sized enterprises.

[0035] The use process of this utility model:

[0036] First, install the device in place, install the capping structure at the rear end of the conveyor belt 2 on the capping machine body 1, and connect the photoelectric sensor 6 to the control device, and then start the device. The wet wipes box arrives on the conveyor belt 2 and moves backward with the conveyance of the conveyor belt 2. When the wet wipes box arrives between the two preliminary guides 4, the lateral movement space of the wet wipes box gradually shrinks, that is, the preliminary guide 4 gradually pushes the wet wipes box inward, so that it tends to the direction opposite to the conveying direction of the conveyor belt 2, and then continues to move to the position of the photoelectric sensor 6. The photoelectric sensor 6 detects the wet wipes box. After passing, a signal is sent to the control device. After a certain delay, when the wet wipes box reaches between the two correction plates 9, the control device controls the drive cylinder 13 to retract, and the tension spring 12 drives the correction plate 9 to push inward, thereby pushing the wet wipes box to the center position on the conveyor belt 2. When it reaches the specified position, the drive plate 11 contacts the limit plate 16 and stops automatically. The rollers 5 on both sides of the wet wipes box are driven to rotate without generating a direct force with the correction plate 9. Then the drive cylinder 13 is extended, driving the correction plate 9 to leave the wet wipes box. The wet wipes box reaches the cover-sticking position and can be covered.

[0037] When producing wet wipes of different widths, the position of the limit plate 16 can be adjusted according to the size: start the limit motor 17, which drives the limit plate 16 to move, thereby adjusting the limit position of the drive plate 11, and then adjusting the limit position of the correction plate 9. The drive cylinder 13 can move quickly, and the thread-driven limit plate 16 can ensure accurate movement position with high precision.
