Non-woven fabric bag trepanning machine

Abstract

The invention relates to a non-woven fabric bag trepanning machine. A rack is included and provided with a feeding platform, a bag body expanding mechanism and a trepanning mechanism. The bag body expanding mechanism comprises a transmission assembly and a tight expanding assembly. The transmission assembly comprises a horizontal sliding frame, a lead screw, a horizontal drive motor, an upper negative pressure suction pipe, a lower negative pressure suction pipe, an upper drive air cylinder and a lower drive air cylinder. The rack is provided with a horizontal track. A vertical track is arranged on the horizontal sliding frame. The lead screw is rotationally arranged on the rack. The horizontal sliding frame is in threaded connection to the lead screw. The vertical downward side of the upper negative pressure suction pipe is provided with an upper adsorption port, and the vertical upward side of the lower negative pressure suction pipe is provided with a lower adsorption port. The tight expanding assembly comprises a tight expanding module, and the tight expanding module is provided with hole-position-corresponding die hole positions. By adoption of the above scheme, the non-wovenfabric bag trepanning machine is provided, sewn non-woven fabric bags can be expanded, the parts needing trepanning are directly punched, and quantitative and high-precision production of non-woven fabric bags is achieved.

Description

technical field [0001] The invention relates to non-woven fabric processing equipment, in particular to a non-woven fabric bag opening machine. Background technique [0002] Non-woven bag is a kind of green product, tough and durable, beautiful in appearance, reusable, washable, silk screen printing advertisement, mark, and long service life. [0003] Among them, in the production process of non-woven bags, according to the design requirements, it is necessary to perform operations such as opening holes and printing patterns on the surface of non-woven bags. [0004] Among them, the operation of opening holes in the existing non-woven bags is generally carried out when the non-woven bag is in the non-woven fabric, and then the non-woven fabric that has been opened is cut, sewed and other processes. Realize the forming of the bag body. [0005] The existing problems in the processing of non-woven bags are as follows: 1. Since the non-woven fabrics have been perforated and p...

Problems solved by technology

[0005] The existing problems in the processing of non-woven bags are as follows: 1. Since the non-woven fabrics have been perforated and processed, subsequent cutting and sewing will cause deviations in the processed holes due to production errors. 2. For non-woven bags of the same size and different hole position models, if the holes are opened when the non-woven fabric is made, because the opening rate of the cloth is extremely high, and the cloth is put into a roll, It will lead to uncontrollable production volume, making quantitative production inconvenient and causing waste of resources
