Description

Technical Field

[0001] The present invention relates to a mask manufacturing machine, in particular to a head-mounted KN95 mask machine. Background Art

[0002] KN95 mask is a common mask. Its production methods are generally divided into two types: one is to use a mask sheet shearing machine to completely cut out the mask sheet from the cloth tape of the cloth roll, and then use a conveying mechanism to convey the mask sheet to the mask ear strap machine for ear strapping; the other is to use a mask sheet shearing machine to cut off the outer edges of the mask sheet at both ends, and then convey the cut cloth tape to the mask ear strap machine for ear strapping. After the ear straps are put on, they are cut into single masks by the mask sheet shearing machine again. However, in these two mask production methods, the mask sheets are horizontally laid when the ear straps are put on, and the ear straps are wound into a U shape by the existing ear strap rotating mechanism, and then the ear straps are pressed from top to bottom by the ear strap welding mechanism for welding. The two ends of each ear strap can only be welded to one end of the mask sheet, and the two ends of an ear strap cannot be made to bypass the bottom of the mask sheet and welded to the two ends of the mask sheet respectively. Therefore, the ear straps of the existing KN95 masks can only be worn on both ears. Summary of the invention

[0003] In view of the defects of the existing KN95 mask machines, the technical problem to be solved by the present invention is to provide a head-mounted KN95 mask machine that can produce ear straps that are not fixed on the ears.

[0004] In order to achieve the above object, according to one aspect of the present invention, the present invention is implemented by the following technical measures: a head-mounted KN95 mask machine, comprising: a machine platform, wherein a relative upper ear strap mechanism and a folding mechanism are arranged above the machine platform, and the upper ear strap mechanism and the folding mechanism are both controlled by a controller,

[0005] The folding mechanism includes a horizontal transition roller frame, a triangle plate, a roller frame, a support rod and a base. The horizontal transition roller frame is provided with two horizontal transition rollers in contact with each other. The base is arranged on the machine platform between the horizontal transition roller frame and the upper ear belt mechanism. One side of the triangle plate is hinged to the base, and the hinged side of the triangle plate is opposite to the horizontal transition roller frame. A support rod capable of lifting the triangle plate is fixed at the lower end of the other side of the triangle plate, so that the triangle plate is arranged obliquely upward. A roller is fixed on the roller frame, and the roller is opposite to the triangle plate.

[0006] The upper ear strap mechanism is divided into two groups, and each group of the upper ear strap mechanism includes a frame, parallel slide rails, a wire cutting device and a wire pulling device. The frame is composed of a support rod and a fixed plate fixed above the support rod. An ear wire storage seat is fixed to the upper end of the fixed plate, and two opposite welding devices are fixed to the lower end of the fixed plate, and the welding guns of the two welding devices are horizontally opposite to each other. The wire cutting device and the wire pulling device are separately arranged on the parallel slide rails and are opposite to each other. A wire clamping device is also arranged on the machine platform outside the parallel slide rails. The wire clamping device includes a fixed seat, a pushing cylinder, two clamping arms and clamping arm cylinders and clamping arm motors corresponding to the two clamping arms. The fixed seat is arranged on one side of the parallel slide rails through the pushing cylinder and the slide rails. Two clamping arm motors are arranged on the fixed seat. Clamping arm cylinders are arranged at the front ends of the rotating shafts of the two clamping arm motors. Clamping arms are arranged at the front ends of the clamping arm cylinders. The two clamping arms are located above the parallel slide rails.

[0007] The machine platform is also provided with a positioning piece, which is an L-shaped iron piece, the vertical end of which is a fixed end, and the horizontal section is arranged between two welding devices and two clamping arms of the two sets of upper ear strap mechanisms.

[0008] The head-mounted KN95 mask machine adds a folding mechanism and a positioning piece on the basis of the existing KN95 mask machine, and changes the turntable rotating upper ear strap of the existing KN95 mask machine into a clamping arm flipping upper ear strap, and changes the vertical welding setting of the existing KN95 welding mechanism into horizontal relative welding to realize the welding of the two ends of the ear strap to the two ends of the mask sheet respectively.

[0009] Furthermore, the wire pulling device comprises a clamping device and a belt device, the clamping device is movably fixed on the parallel slide rails, and can slide back and forth along the parallel slide rails driven by the belt device. The above design structure is simple and reasonable.

[0010] Furthermore, the upper ear strap mechanism is divided into two groups, and the positioning pieces are divided into two pieces. The above design is to increase production efficiency.

[0011] Furthermore, the mask machine also includes a transition mechanism, which is fixed on the machine platform and is located between the upper ear band mechanism and the folding mechanism. The transition mechanism is composed of a vertical transition roller frame and two contacting vertical transition rollers arranged in the vertical transition roller frame. The above design is not only convenient for processing, but also can prevent the mask from opening during transportation.

[0012] Furthermore, there are multiple transition mechanisms, which are arranged in a line.

[0013] Compared with the prior art, the invention has the advantage that one of the two ear straps of the KN95 mask is put on the neck and the other is put on the head for use, so as to prevent the ear straps from being hung on the ears for a long time and causing ear pain.
