Problems solved by technology

[0004]In the prior art, when cutting the melt blown cloth, it often adopts a semi-automatic cutting method, which needs to be placed and fixed manually. Manual collection is required, but manual placement and fixing not only cannot accurately carry out horizontal fixing, resulting in cutting deflection, but also the overall work efficiency is low. For this reason, the present invention provides a cutting device based on melt-blown cloth production

Embodiment 1

[0029] Such as Figure 1 to Figure 5 As shown, a cutting device based on the production of melt-blown cloth according to the embodiment of the present invention includes a box body 1; the side walls on both sides of the box body 1 are provided with a feed port 11 and a discharge port 12; The box body 1 is provided with a transmission assembly; the transmission assembly includes a transmission roller 14 and a transmission belt 13; a pair of symmetrically distributed transmission rollers 14 are rotatably connected to the inner wall of the box body 1, and the transmission rollers 14 are driven by a motor; The drive rollers 14 are driven by a drive belt 13; the drive belt 13 is provided with a group of first through holes 15; the side wall of the box body 1 is fixed with a concave plate 16 through a fixing column; the concave plate 16 is located in the middle of the transmission belt 13, and the top of the concave plate 16 and the bottom of the transmission belt 13 are attached to...

Embodiment 2

[0039] Such as Figure 6 As shown in Comparative Example 1, another embodiment of the present invention is: a group of third grooves 56 are provided on the trapezoidal inclined surface of the pressure rod 36; Roller 57; During work, when pressing bar 36 moves down this moment, trapezoidal inclined-plane can contact with the trapezoidal inclined-plane of push rod 35, and then promote push bar 35 to move by pressing bar 36, but mutual promotion can produce larger when both contact. Sliding friction, in order to reduce the influence of friction, so the trapezoidal inclined surface of pressure bar 36 is provided with roller 57, and sliding friction is changed into rolling friction, and then reduces the generation of friction.

[0040] Working principle: first place the melt-blown cloth that needs to be cut on the transmission belt 13, then start the aspirator, and the aspirator sucks air through the first through hole 15 on the top of the concave plate 16 and places it on the tran...

Abstract

The invention belongs to the technical field of melt-blown cloth production, and particularly relates to a cutting device for melt-blown cloth production. A feeding port and a discharging port are formed in the side walls of the two sides of the box body. A transmission assembly is arranged in the box body; the transmission assembly comprises a transmission roller and a transmission belt; the inner wall of the box body is rotationally connected with a pair of driving rollers which are symmetrically distributed, and the driving rollers are driven by a motor; the pair of transmission rollers are in transmission through a transmission belt; a group of first through holes are formed in the transmission belt; the side wall of the box body is fixedly connected with a concave plate through a fixing column. A cutting device for melt-blown cloth production aims to solve the problems that when melt-blown cloth is cut, a semi-automatic cutting mode is usually adopted, manual placement and fixation are needed, manual collection is also needed after mechanical cutting, however, due to manual placement and fixation, horizontal fixation cannot be accurately conducted, cutting deflection is caused, and the cutting efficiency is high. And the overall working efficiency is low.

Description

technical field [0001] The invention belongs to the technical field of melt-blown cloth production, and specifically relates to a cutting device based on melt-blown cloth production. Background technique [0002] The core material of the mask is melt-blown cloth, which is made of polypropylene as the main raw material. The ultra-fine fibers with a unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has good filterability , shielding, heat insulation and oil absorption, when producing masks, it is necessary to cut the melt blown cloth. [0003] A Chinese patent with a publication number of CN212445550U discloses a cutting device for the production of melt-blown cloth, including a table board, feet are fixed at the four corners of the bottom of the table board, and two sides are fixed on one side above the table board. The two side plates are rotated and connected with rollers on the upper and lower sides. Th...
