Description

Feeding structure of mask machine

Technical Field

The utility model belongs to the technical field of the technique of gauze mask processing and specifically relates to a material loading structure of gauze mask machine is related to.

Background

The mask machine is characterized in that various masks with certain filtering functions are manufactured by processes of hot pressing, folding forming, ultrasonic welding, waste material cutting, ear band nose bridge strip welding and the like on multiple layers of non-woven fabrics, mask equipment is not a single machine, and various different processes are completed by matching multiple machines.

Among the prior art, the feed structure of gauze mask machine is shown in figure 1, including frame 100, installs installation axle 110 on the frame 100, has seted up the opening on the installation axle 110, and the joint has the spacing ring in the opening, has seted up the installing port on the spacing ring, and the interference joint has the hand wheel 330 that is used for driving installation axle 110 to take place the pivoted in the installing port. When the feeding work of the roll-shaped cloth needs to be carried out, the hand wheel and the limiting ring are sequentially detached from the mounting shaft, the roll-shaped cloth is clamped on the mounting shaft, then the limiting ring is clamped into the opening again to lock the roll-shaped cloth, and finally the hand wheel is clamped into the mounting port.

The above prior art solutions have the following drawbacks: above-mentioned device is carrying out the material loading during operation of roll-like cloth, because lack the interact power of supporting tightly between installation axle and the roll-like cloth, consequently roll-like cloth can rotate relatively with the installation intertube at the in-process of feeding, and then makes the cloth feeding in-process can appear the condition that the subregion is slack, further produces the influence to the production process of gauze mask.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a not enough to prior art exists, the utility model aims at providing a feed structure of gauze mask machine can be so that there is the interact power between installation axle and roll-like cloth, and then avoids roll-like cloth to take place relative rotation between the axle at the feeding in-process and installation, further improves the quality of gauze mask production.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a feed structure of gauze mask machine, includes the frame, install the installation axle in the frame, T word groove has been seted up along the axial to the installation axle, T word groove edge the installation axle is radially slided and is connected with the compact heap, the compact heap is kept away from the one end of installation axle center is provided with the butt cambered surface, T word inslot is installed and is supported tight spring, the both ends of supporting tight spring butt respectively T word groove with the compact heap, the one end of installation axle is provided with anticreep spare.

By adopting the technical scheme, when the roll-shaped cloth needs to be installed on the installation shaft, the limitation of the anti-release piece on one end, away from the rack, of the installation shaft is removed, when the roll-shaped cloth is installed on the installation shaft, the inner wall of the roll-shaped cloth pushes the end of the pressing block to move into the T-shaped groove, the pressing block further compresses the abutting spring, and the pressing block further generates abutting force on the inner wall of the roll-shaped cloth due to the elastic force of the abutting spring, so that the mutual acting force exists between the roll-shaped cloth and the installation shaft, and the probability of relative rotation between the roll-shaped cloth and the installation shaft is reduced to a certain extent; the setting of anticreep piece plays the limiting displacement to roll-like cloth, reduces roll-like cloth and takes place the probability that drops from the installation epaxial, plays the effect of sealing T font groove port simultaneously.
