detailed description

In view of the defects existing in the prior art, the object of the present invention is to provide a paper folding device for a paper bag machine, which uses a baffle and a bent piece to complete the paper folding process according to the upper mouth pressing. The device is integrated on the paper bag machine to realize multi-purpose use of one machine, improve the production efficiency of the paper bag and reduce the production cost. Moreover, the paper folding upper device has a simple structure, simplifies the debugging process, realizes quick debugging, and is convenient to operate. The present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , FIG. 2 and FIG. 4 , the paper folding device 200 includes a square support rod 260 and a folding port assembly. The upper surface of the support rod 260 is provided with a paper board 270 and a paper board 270 . The outer end protrudes from the outer side of the support rod 260, the inner side of the support rod 260 is provided with a paper pad 280, and the rear side of the paper block 280 is engaged with the inner end surface of the support rod 260 and the paper board 270, and the paper pad 280 The upper surface is inclined downwardly to facilitate the conveyance of the paper 100, and the front side is curved to fit the paper feed roller 400.

The baffle 230 is received above the paper pad 280. The lower end of the baffle 230 is curved, and the bottom surface thereof is attached to the upper surface of the paper pad 280. The paper 100 to be processed is added to the upper of the paper feed roller 400. After the model of the upper mouth is folded, the paper 100 enters the baffle 230 and is subjected to a subsequent folding process.

The baffle 230 is fixed on the baffle fixing rod 231. The baffle fixing rod 231 is fixed with a round strut 210 at both ends thereof, and is fixed on the paper bag machine by the round strut 210. The inner side of the round strut 210 is screwed to fix the clamping block 220. The adjusting block 250 is further disposed on the inner side of the clamping block 220 at one end, and is screwed tightly, and has a simple structure, which facilitates assembly and debugging of the machine device by the operator.

1 and 3, the upper end of the baffle 230 is provided with a bent piece 240. The bent piece 240 is screwed and fixed on the bent piece fixing strip 242, and is locked by the fixed strip locking piece 243. The bent piece fixing strip 242 is used for The gear stops during the paper transport, and the fixed bar lock block 243 is screwed to the back of the shutter 230. The upper end of the bent piece 240 is provided with a sliding slot 241. The screw is fixed on the screw hole of the bending piece fixing strip 243 through the sliding slot 241, and the upper and lower positions of the bending piece 240 can be adjusted by changing the fixing position of the screw in the sliding groove 241. .

According to the invention, the paper folding upper device is two groups, and the front set of folding upper device is suitable for the ordinary paper bag, which is folded once, and the rear set of folding upper device is for the special paper bag which needs to strengthen the handle strength, and two The secondary folding process.
