Description

Technical Field

[0001] This utility model relates to the field of diaper production technology, specifically to a left and right waist adhesive device on a diaper production line. Background Technology

[0002] The function of the left and right waist tabs is to connect the front and back sides of the diaper together after it is put on, forming a "pants" shape. This ensures a snug and comfortable fit and prevents the diaper from slipping down. The left and right waist tabs are usually bonded to the diaper using adhesive. Currently, the bonding of the diaper to the waist tabs on the production line is achieved through the following working principle: a three-axis pressing mechanism consisting of an adsorption transfer roller, a cutting roller, and a pressing and adhesive aid roller. Figure 1 The device rotates actively in the indicated direction. The working frequency of the three axes is synchronized with the conveying frequency of the diaper products. The continuous waistband products are conveyed to point A (i.e., the contact point with the cutter roller) by the adsorption transfer roller and cut into small segments of the required size. Then, they are adsorbed and transferred to point B (i.e., the contact point with the pressing and bonding roller). The pressing and bonding roller with an eccentric structure applies pressure and bonds the product to specific parts of the diaper.

[0003] Chinese patent CN102078248B discloses a left and right waistband adhesive device on a diaper production line. The technical solution is to provide an eccentric sleeve on the roller shaft of the pressing and adhesive roller. A ring sleeve is movably connected to the outer circumference of the eccentric sleeve through a bearing. In the non-pressing state, the ring sleeve rotates with the pressing and adhesive roller shaft and its eccentric sleeve. When the eccentric position of the eccentric sleeve and the adsorption transfer roller jointly apply pressure to the diaper and its left and right waistbands, the ring sleeve can rotate with the adsorption transfer roller and be synchronized with the linear speed of the adsorption transfer roller and the diaper product.

[0004] However, the left and right waist tape bonding device on the diaper production line does not have tension adjustment function during use. During the diaper conveying process, wrinkles or deviations are prone to occur, which reduces the bonding quality of the left and right waist tapes, reduces the quality of the finished diaper, and is not conducive to the production, processing and use of diapers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a left and right waist tape bonding device for a diaper production line. This solves the problem that existing left and right waist tape bonding devices on diaper production lines do not have tension adjustment capabilities, and that diapers are prone to wrinkling or shifting during transport.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a left and right waist adhesive device for a diaper production line, comprising a receiving box, an adsorption transfer roller is provided counterclockwise at the lower part of the inner cavity of the receiving box, a pressing and adhesive aid roller is provided clockwise above the adsorption transfer roller at the inner cavity of the receiving box, a cutter roller is provided clockwise at the lower part of the inner cavity of the receiving box in contact with the surface of the adsorption transfer roller, and a first tension roller is provided rotatably on one side of the inner cavity of the receiving box;

[0007] Support blocks are fixedly connected to the middle of the front and rear sides of the container. A lifting rod is pulled out of the support block. A positioning seat is fixedly connected to the top of the lifting rod. A second tension roller is rotatably arranged between the two positioning seats. A drive mechanism is provided on the top of the container to drive the two lifting rods to move up and down.

[0008] Furthermore, the side wall of the receiving box is provided with a drive assembly for driving the counterclockwise rotation, the clockwise rotation of the pressing and bonding roller, and the clockwise rotation of the cutting roller.

[0009] Furthermore, a first conveying roller is rotatably arranged at the bottom of the other side of the inner cavity of the container, a second conveying roller is rotatably arranged at the lower part of the other side of the inner cavity of the container, and a third conveying roller is rotatably arranged at the middle of the other side of the inner cavity of the container.

[0010] Furthermore, a distance sensor is fixedly connected to the bottom of the support block.

[0011] Furthermore, a first support roller is rotatably provided on the upper part of the other side of the inner cavity of the container, and a second support roller is rotatably provided on the lower part of the other side of the inner cavity of the container.

[0012] Furthermore, the drive mechanism includes a protective box, a motor, a threaded rod, and a threaded sleeve. The protective box is fixedly connected to the top of the receiving box, the motor is fixedly connected to the bottom of the inner wall of the protective box, the threaded rod is fixedly connected to the output shaft of the motor, the threaded sleeve is threadedly connected to the surface of the threaded rod, a support rod is fixedly connected to the side wall of the threaded sleeve, the top end of the support rod is pulled out to the outside of the protective box and is fixedly connected to a top plate, and the top ends of the two lifting rods are fixedly connected to the lower surface of the top plate.

[0013] Furthermore, the side wall of the container is detachably equipped with an inspection cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are that after the adsorption transfer roller, the cutter roller and the pressing and bonding roller work, the left and right waist tabs of the diaper can be bonded to the surface. During the bonding process, the lifting rod can be moved up and down by the drive mechanism, thereby adjusting the distance between the second tension roller and the first tension roller. This facilitates the adjustment of the tension during the diaper conveying process, avoids wrinkling or deviation during the diaper conveying process, improves the finished product quality of the left and right waist tabs bonding process, and is beneficial to the production, processing and use of diapers.
