[0001] The utility model relates to the technical field of sanitary product processing devices, and more specifically, to a waistline cutting and transfer mechanism for sanitary products. Background Art

[0002] In the production field of disposable sanitary products, pull-up pants are more comfortable to wear than diapers, but the production process of pull-up pants requires an additional waist cutting process. After the waist cutting process, the next process of pull-up pants is the transfer process, which rotates the product 90° to facilitate the subsequent folding process; traditional pull-up pants waist cutting devices, such as the diaper elastic waist cutting mechanism with patent publication number CN106514781A, only have a waist cutting process. In order to meet the folding and packaging requirements, a device must be added to transfer the pull-up pants after the waist is cut before folding and packaging. However, this method of adding a transfer device often has a problem of uneven transition from the waist cutting process to the transfer process, which affects the product transfer and folding effect, resulting in low overall production efficiency and low yield rate.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The utility model provides a waist cutting and transfer mechanism for sanitary products, such as Figure 1 As shown, it includes: a mounting frame 1; the mounting frame 1 is provided with: a transfer component 2 for driving the sanitary product to move, a pressing component 3 for pressing the sanitary product on the transfer component 2, a cutting component 4 for cutting the waistline of the pressed sanitary product, and a transmission component 5 for shifting the sanitary product after the waistline is cut.

[0023] Specifically, the newly produced sanitary products are transported into the mechanism through the transfer component 2. During the transfer process, the clamping component 3 will press the sanitary products on the transfer component 2 to prevent them from detaching or loosening from the transfer component 2 during the transfer process, resulting in the inability to complete the cutting process; during the transfer process, the cutting component 4 will perform the cutting process on the sanitary products. After the cutting is completed, the transmission component 5 will rotate the cut sanitary products to realize the transfer process; these two processes are completed in the same set of mechanisms, and there will be no transition problems between the two processes, which improves the quality of the completed processes.

[0024] Furthermore, the transfer assembly 2 includes: a first guide roller 21, a first gear plate 22, a plurality of adsorption plates 23 for adsorbing sanitary products, and a plurality of negative pressure seats 24 corresponding one by one to the plurality of adsorption plates 23; the first guide roller 21 is arranged on the mounting frame 1; the adsorption plate 23 is arranged on the negative pressure seat 24; the plurality of negative pressure seats 24 are arranged in a ring-shaped and equidistant manner on the first gear plate 22, and they are all transmission-connected to the first gear plate 22.

[0025] Specifically, Figure 2 As shown, when the sanitary product just enters the mechanism, the first guide roller 21 is used to guide the sanitary product to prevent its entry position from deviating; the adsorption plate 23 on the negative pressure seat 24 will adsorb the sanitary product and make it rotate with the first gear plate 22. During the rotation, the cutting component 4 will cut the waist side of the sanitary product.

[0026] Specifically, the driving method of the first gear plate 22 can be a driving motor, a driving motor or other driving device that has the function of making the first gear plate 22 rotate at a uniform speed. It is one of the commonly used technologies by people in this field and will not be described one by one in this specification; a driving motor is selected in this embodiment.

[0027] Furthermore, the transmission assembly 5 includes: a first guide wheel 51, and a plurality of transmission shafts 52 corresponding one-to-one to the plurality of adsorption plates 23; the first guide wheel 51 is fixedly arranged on the mounting frame 1; an S-shaped guide groove 511 is arranged on the first guide wheel 51; one ends of the plurality of transmission shafts 52 are respectively placed in the S-shaped guide groove 511; the other ends of the plurality of transmission shafts 52 are respectively corresponding one-to-one to the plurality of adsorption plates 23 for transmission connection.

[0028] Specifically, Figure 2 and Figure 4 As shown, after the waistline is cut, one end of the transmission shaft 52 is placed in the S-shaped guide groove 511 and abuts against its inner wall. The transmission shaft 52 will move along the S-shaped guide groove 511 on the first guide wheel 51, thereby driving the adsorption plate 23 to rotate, thereby realizing a 90-degree rotation of the sanitary product and completing the transfer process.

[0029] Furthermore, the cutting assembly 4 includes: a knife roller 41, a transmission gear 42, and a cutter 43; the knife roller 41 is rotatably connected to the mounting frame 1; the transmission gear 42 is fixedly connected to the knife roller 41; the transmission gear 42 is meshingly connected to the first gear plate 22; the cutter 43 is arranged on the knife roller 41; a plurality of knife anvils 44 adapted to the cutter 43 are also arranged on the first gear plate 22; and one knife anvil 44 is arranged between two adjacent negative pressure seats 24.

[0030] Specifically, Figure 3 and Figure 5 As shown, the transmission gear 42 and the first gear plate 22 are meshed and connected, so that the first gear plate 22 and the knife roller 41 rotate synchronously, and the cutting range and length can be controlled by adjusting the rotation ratio (ratio of the linear speed); a knife anvil 44 is provided on the first gear plate 22, so that the cutter 43 can cut more evenly and increase the service life of the cutter 43.

[0031] Furthermore, a negative pressure tube 6 is provided on the mounting frame 1 ; a negative pressure cavity 241 is provided on the negative pressure seat 24 ; the negative pressure tube 6 is communicated with the negative pressure cavity 241 ; and the negative pressure cavity 241 is communicated with the adsorption disk 23 .

[0032] Specifically, Figure 2 As shown, the negative pressure system is connected to the outside through the negative pressure pipe 6, so that the adsorption plate 23 has adsorption force to adsorb sanitary products, and the adsorption force on the adsorption plate 23 can be controlled by adjusting the negative pressure system to better meet the actual production needs and further improve the adaptability. The use and control of the negative pressure system is one of the commonly used techniques by people in this field, and will not be described in detail in this manual.

[0033] Furthermore, the clamping assembly 3 includes: a plurality of support rollers 31, a driving roller 32, and a clamping belt 33; the plurality of support rollers 31 are rotatably disposed on the mounting frame 1; the driving roller 32 is rotatably disposed on the mounting frame 1; and the clamping belt 33 is wound around the driving roller 32 and the plurality of support rollers 31.

[0034] Specifically, Figure 2 As shown, the rotation speed of the driving roller 32 is the same as the rotation speed of the first gear plate 22, so that the clamping belt 33 can better compress and press the sanitary products on the adsorption plate 23 to prevent them from falling off or deviating from the adsorption plate 23 due to environmental factors such as vibration; the clamping belt 33 presses and abuts the sanitary products to keep the sanitary products in a taut state, thereby improving the accuracy of cutting the waistline of the products; the rotation speed of the driving roller 32 cannot be greater than or less than the rotation speed of the first gear plate 22, otherwise the clamping belt 33 will be too fast or too slow, causing the sanitary products to deviate from the adsorption plate 23.

[0035] In the specific implementation process, the sanitary product is transported from the first guide roller 21 to the adsorption plate 23 on the first gear plate 22. The adsorption plate 23 will adsorb the sanitary product and drive it. As the first gear plate 22 rotates, when passing through the clamping component 3, the driving roller 32 and the first gear plate 22 have the same rotation speed, so that the clamping belt 33 rotates synchronously to compress the sanitary product; after compression, because the transmission gear 42 on the knife roller 41 is in a meshing connection state with the first gear plate 22, the rotation speed (angular velocity) of the knife roller 41 is also the same as that of the first gear plate 22. The rotation speed (angular velocity) of 22 is the same, and the cutter 43 on the knife roller 41 can be accurately aligned with the anvil 44 between two adjacent adsorption plates 23, so as to achieve accurate cutting and severing of the sanitary product and complete the waistline cutting process; after the sanitary product is cut and severed, one end of the transmission shaft 52 will move on the S-shaped guide groove 511 on the first guide wheel 51. When moving, the other end of the transmission shaft 52 will drive the adsorption plate 23 to rotate 90 degrees, so that the sanitary product completes the transfer process, which is convenient for folding and packaging after discharge.

[0036] The utility model discloses a waist cutting and transfer mechanism for sanitary products, which combines the cutting process and the transfer process into a set of mechanisms, first completing the waist cutting process and then completing the transfer process; the two processes are completed in the same set of mechanisms, and there is no transition problem between the two processes, thereby improving the quality of the process completion, improving the production efficiency of sanitary products, and increasing the production yield rate.

[0037] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
