Problems solved by technology
[0002] The existing bagging devices can perform stable bag opening operations for bags such as film-coated and air-tight bags, and most of them adopt the bag-opening method of suction cup adsorption. Wait for the air-permeable packaging bag to be opened, and the existing variable-diameter automatic bag opening and sewing device structure and operation are cumbersome, and the efficiency is low

The invention discloses a variable diameter automatic bag opening and suturing device, which relates to the technical field of bagged product production. The variable diameter automatic bag opening and stitching device includes a bag unfolding mechanism, a bag carrying mechanism and a stitching mechanism. The reel is used to connect with the bag body, and can wind the end of the bag body, so that the bag mouth of the bag body is in a staggered state. The moving part can drive the clamping part and the bag-supporting part to move to the mouth of the bag, the clamping part can clamp the inner side of the inner layer of the bag mouth, and the bag-supporting part can move away from the clamping part to abut against the inner side of the outer layer of the bag mouth , so as to expand the bag mouth together with the clamping piece, the sewing mechanism is arranged close to the bag carrying mechanism, and can sew the bag mouth. The variable diameter automatic bag opening and suturing device has the characteristic of being able to perform relatively stable bag opening operations on breathable bags such as woven bags.
Description
technical field [0001] The invention relates to the technical field of bagged product production, in particular to a variable-diameter automatic bag opening and suturing device. Background technique [0002] Existing bagging devices can stably open bags for film-coated, airtight bags, etc. Most of them use suction cups to open bags. However, this bag-opening method is difficult for non-woven bags and non-film-coated woven bags. It is necessary to wait for the breathable packaging bag to perform the bag opening operation, and the structure and operation of the existing variable diameter automatic bag opening and suturing device are complicated and the efficiency is low. [0003] In view of this, it is particularly important to develop and design a variable-diameter automatic bag opening and suturing device that can solve the above technical problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a variable diameter automatic bag openi...
