Description

A kind of woven bag cuts wrinkle resistant mechanism
Technical field
The utility model belongs to knitting cutting apparatus field, relates to a kind of woven bag and cuts wrinkle resistant mechanism.
Technical background
In the woven bag production process, need, carry out the operation of bag tape edge then the continuous knitting section of cutting into.Woven bag cuts general employing cutting knife, adopts conveying roller will continuous knitting to carry and make the knitting front end cross cutting knife towards the cutting knife direction, and the length of crossing the cutting knife part when knitting reaches the requirement of making bag, uses the cutting knife cut-out.In the process of carrying knitting, cutting knife partly is provided with the blowing mouth that blows towards the place ahead, and the knitting of crossing cutting knife is upwarped by blowing effect easily, especially delivery speed is fast more, the knitting end also is subjected to the big more windage of advancing, and forms fold easily, influences the yield rate of woven bag.And delivery speed is fast more, and the knitting end is upwarped by windage to form the probability of fold high more, and the delivery speed of knitting is subjected to above-mentioned restriction, has restricted the production efficiency of woven bag greatly.
The CN202097998U patent document of Patent Office of the People's Republic of China's bulletin on January 4th, 2012, name is called the wrinkle resistant structure of woven bag body, determine the front and back side with throughput direction, this device is provided with in the front side of cutting knife and send bag wheels, at the cutting knife rear side conveying clip wheel group is set, carry clip wheel group rotating speed greater than sending a bag wheels rotating speed, the fast conveying speed discrepancy in slow back before utilizing makes knitting can tensioning not produce fold through the cutting knife position time.But, there is following defective in this device: 1, carry the clip wheel group sheathed belt of clip wheel difference up and down, adopt the knitting after two belt clampings conveying cuts up and down, the synchronism of two belts own just is difficult to guarantee, and owing to two belts tensile force separately is difficult to be consistent, course of conveying can produce in various degree flexible, and above-mentioned reason all can cause knitting can produce fold at belt clamping transport portion; 2, cut the back when the tape edge bench board shifts when knitting, the vertical strap throughput direction is pulled because knitting is clamped between two belts also, is easy to generate fold; 3, after knitting once cuts and finishes, how cutting surface is accurately sent into carry between the clip wheel group and had a difficult problem.
Summary of the invention
