Description

Disposable sanitary article servo drive production facility and negative pressure transmission assembly thereof Technical Field The invention relates to the field of transmission equipment, in particular to servo drive production equipment for disposable sanitary products and a negative pressure transmission assembly thereof. Background In the production process of disposable sanitary products, such as sanitary napkins, diapers and nursing pads, the release paper is generally used to protect the adhesive layer or to realize temporary separation between materials, so that the release paper needs to be continuously and stably conveyed on the production line through a conveying device. In order to prevent the release paper from tilting, shifting or shaking in the conveying process, a negative pressure conveying belt device is generally adopted in the existing production equipment, and the release paper can be attached to the surface of the conveying belt in the conveying process by arranging a negative pressure cavity below the conveying belt and utilizing vacuum air suction to form an adsorption effect, so that the position of the release paper is kept stable and the processing precision of subsequent procedures is ensured. In the disposable sanitary article production equipment, in order to adapt to the rapid switching requirement of products with different specifications, a conveying unit is often designed into a movable structure so as to give up an operation space when a forming die is replaced. In the prior art, the movable conveying unit is driven by a cylinder to be matched with a linear guide rail to realize automatic advance and retreat, or is locked and fixed by a bolt after manual push-pull. However, the above structure has problems of low die changing efficiency and poor adjustment accuracy in practical application. Although the cylinder driving mode realizes automatic control, the stability of the cylinder driving mode at the stop position is weak, when the equipment runs at high speed, the head of the equipment is easy to slightly displace due to the vibration and external interference of the conveying unit, and then the gap between the conveying belt and the material receiving part of the die is changed, so that the stability of material delivery is affected. The manual bolt locking mode does not need an additional power source and is simple in structure, but the locking and releasing operation of the manual bolt locking mode needs to screw or loosen a plurality of bolts one by means of tools, the operation steps are tedious and time-consuming, particularly when the extending amount of the conveying unit needs to be adjusted according to the specification change of the die, the manual bolt locking mode is required to be completely loosened and is movable, the manual bolt locking mode also needs to be locked again and is subjected to secondary verification after adjustment, and the die changing efficiency is seriously affected in the whole process. Therefore, a servo drive production device for disposable sanitary products and a negative pressure transmission component thereof are provided for solving the problems of low die changing efficiency and poor adjustment precision. Disclosure of Invention The invention aims to provide a servo drive production device for disposable sanitary products and a negative pressure transmission assembly thereof, which solve the problems of low die changing efficiency and poor adjustment precision in the aspect of adaptability of the device. To achieve the purpose, the invention adopts the following technical scheme: A servo drive production device for disposable sanitary articles and a negative pressure transmission assembly thereof comprise a first groove body and a second groove body which are distributed along a first direction in sequence corresponding to a die wheel, wherein a first position and a second position are arranged between the die wheel and the second groove body along the first direction in sequence, and a part of area of the first position is positioned in the die wheel; The first groove body is connected with the second groove body through the telescopic piece, the telescopic piece comprises a driving part and a telescopic part, wherein the driving part is respectively arranged on the second groove body, the telescopic part is arranged on the first groove body, the driving part is switched to be in a state, the first groove body is switched between a first position and a second position through the telescopic part moving along the first direction, and the length of the telescopic part is adjusted to enable the first groove body to move along the first direction at the first position. The drive part comprises a guide block, a support arm and a handle arm, wherein the guide block is arranged on the second groove body, the telescopic part is inserted into the guide block along the first direction, one end of the support arm is hinged with the gui
