Problems solved by technology

In the current production line, such a mechanism has been able to realize high-speed continuous production of the equipment, but there are still the following defects in actual production: (1) At the position of unwinding the material, when a certain roll of material is used up, it needs to be manually removed. The new coil is set on the unwinding shaft, and a production equipment generally has 5 to 7 kinds of unwinding materials, and every 3 to 8 minutes will use up a roll of material, and then the material needs to be replaced once; each time To change the material, first manually turn the unwinding switch to loosen the paper tube, then take down the paper tube, put a new coil on the air shaft, turn the switch to tighten the coil, and then stick the material head Apply adhesive tape, then pull the material head into the automatic splicing unit, and wait for the material to be spliced; it can be seen that the operation process of changing rolls includes a series of actions such as the operation of unwinding the reel and the operation of the automatic splicing unit. Although the working process is simple, However, the process is complicated, so this station has not realized automatic operation; in the current production equipment, a set of equipment generally needs to be equipped with 3 material changers
The 3 refueling personnel account for half of the 6 start-up personnel of the whole set of equipment. The labor cost is high and the work intensity is high, so the production cost cannot be effectively controlled.
(2) In the automatic splicing unit, when two coils are spliced ​​end to end, a section of the end of the coil that is about to be used up needs to be reserved and fixed on the unwinding shaft so as to be tensioned and spliced ​​with the new coil. The section of material from the automatic splicing mechanism to the unwinding shaft (commonly known as "tailing") is discarded, which easily causes the loss of raw materials, and the loss of raw materials is large, which is also one of the reasons why the production cost cannot be effectively controlled

Abstract

The invention discloses an automatic roll changing and splicing system and method for disposable sanitary product production equipment. In the system, a first coil is arranged on a first unwinding mechanism, the first coil is discharged and then is conveyed by a first unwinding negative pressure conveying device and sent to a main negative pressure conveying device, a second coil is arranged on asecond unwinding mechanism, and the second coil is discharged and then is conveyed by a second unwinding negative pressure conveying device and sent to the main negative pressure conveying device; anultrasonic pressing device is arranged on one side of the main negative pressure conveying device, in the conveying direction of materials, and the ultrasonic pressing device is arranged in front of the first unwinding negative pressure conveying device and the second unwinding negative pressure conveying device. The method comprises the following steps that the first unwinding negative pressure conveying device and the second unwinding negative pressure conveying device alternately convey the coil to the main negative pressure conveying device, and splicing is completed under the cooperationof the main negative pressure conveying device and the ultrasonic pressing device. According to the system, traditional manual operation can be replaced, the roll changing efficiency is high, the waste amount of a tail material is small, and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing disposable sanitary products, in particular to an automatic roll-changing material-feeding system and method for production equipment of disposable sanitary products. Background technique [0002] One of the basic units of disposable sanitary product production equipment (currently mainly including sanitary napkin production equipment, paper diaper production equipment, pull-up trousers production equipment, etc.) is the material rewinding and unwinding unit. The layout of these units is generally as follows: figure 1 As shown, the material unwinding part uses a motor to drive the unwinding shaft to unwind. Each material has two unwinding shafts 1 for each other. The end and end of the machine are spliced ​​together to ensure continuous supply of materials for production. The unwinding reel cooperates with the automatic splicing mechanism, supplemented by the storage mechanism 3, which ensur...
