Embodiment Construction
[0012] refer to Figure 1 to Figure 4 It can be seen that the automatic folding and shaping method of the square bottom bag of the present invention is: earlier the square bottom bag of non-woven fabric material is covered on the hinge model 1 (in the open state) (the bag mouth is inside, the bottom of the bag is outward), and the side inserts Plate 3 (located on both sides outside the hinge model) is driven by the side plate cylinder 4 to push the two sides of the square bottom bag to the opening of the hinge model, and the square bottom bag is forced to fold inward to drive the hinge model 1 on the hinge guide rail 2 Sliding up to carry out folding and hemming actions; then the midsole inserting plate cylinder 6 pushes the midsole inserting plate out to form the bottom of the square bottom bag, thereby completing the automatic folding of the sides and bottom of the square bottom bag action (such as image 3 ; that is, bagging in the horizontal state first, and then folding ...

The invention relates to an automatic square-bottom bag flanging sizing method and device. The method is characterized in that a square-bottom bag is firstly sleeved on a hinge model, two edges of the square-bottom bag are plugged into an opening of the hinge model through a side plugging plate, the square-bottom bag is folded inwards under the stress to drive the hinge model to slide on a hinge lead rail so as to carry out the folding and flanging action; then the square-bottom bag stretches out from a middle bottom plugging plate so as to enabling the formation of the bottom of the square-bottom bag; and then the square-bottom bag is conveyed to an inlet of a sizing arch through a turntable, the bottom of the square-bottom bag is pressed between a bag pulling rubber roll and a conveying main roll and on a conveyor belt assembly through the bag pulling rubber roll, the conveyor belt assembly pulls out the square-bottom bag and conveys the square-bottom bag below a hot sealing plate, the square-bottom bag is hot-pressed and sized through the hot sealing plate, and finally the flanged and sized square-bottom bag is produced. The automatic square-bottom bag flanging sizing device consists of an automatic square-bottom bag sizing mechanism, an automatic square-bottom bag flanging mechanism and a turntable. Due to the adoption of the method and the device, the working efficiency is increased, the production cost is reduced, the produced square-bottom bag is convenient to package, flat, good in quality and difficult to tear and break, and the service life of the produced square-bottom bag is prolonged.
Description
technical field [0001] The invention relates to a fully automatic non-woven bag-making method and bag-making equipment, in particular to a non-woven bag (especially a square bottom bag) folding and shaping method and a device thereof. Background technique [0002] At present, the fully automatic non-woven bag making machine is used to convey, arrange (or press edge, insert edge), cut, and seal the roll-type non-woven fabric to make flat bags, vest bags or shopping bags. And other forms of non-woven bag-making automatic equipment, the bottom of the flat bag (vest bag) produced by it is a flat bottom or square bottom bag. At present, the finished bags manufactured by the non-woven bag making machine are all sorted and packaged by hand-folding, bottom-folding, shaping and shaping, which is slow and ineffective. Since the non-woven material is soft and difficult to shape, it undoubtedly increases the difficulty of manual finishing, and the finishing and packaging of finished ba...
