DETAILED DESCRIPTION

[0014] The utility model will be further described below with reference to the drawings.

[0015] Please refer to Figs. 1-3The utility model discloses an edge pressing device of plastic woven bag, including processing table 1, one side edge of processing table 1 is fixedly connected with vertical board 2, and the upper of processing table 1 is equipped with the board 4 of linking, and the board 4 of linking is fixedly connected with fixed column 8 through the middle of its far away from vertical board 2 one end edge, and one end of fixed column 8 away from the board 4 of linking is equipped with driven column 9, and the one end of driven column 9 away from fixed column 8 is rotatably connected with the flat plate 10, and driven column 9 is the inclined structure of outward expansion, and the flat plate 10 is horizontal parallel with processing table 1, and driven column 9 rotates through torsional spring and fixed column 8, and the bottom four side edges of flat plate 10 are rounded corner structure, and vertical board 2 is L-shaped structure, and the horizontal plate of vertical board 2 is embeddedly connected with telescopic link 3, and telescopic link 3 is detachably connected in the middle of the top sidewall of board 4 of linking through its output end,

[0016] As the technical effect of the scheme is: start telescopic link 3 drive board 4 of linking drop, then through the pre-pressing positioning of pressing plate 7 to bag, then through the expansion of driven column 9 and through the flat plate 10 of subsequent drop to bag and smooth, ensure that bag is in the flat state, because pressing plate 7 just locates the edge of bag and does not completely press dead, thus can ensure that bag keeps in situ unmoved while not affecting the operation of smoothing, and the wrinkle is smoothed, also avoid the problem that the edge is abnormal because of the wrinkle and then affects the overall quality of bag.

[0017] The middle fixed connection of one end edge of the bottom of board 4 of linking and far away from fixed column 8 has adjusting rod 5, and the bottom of adjusting rod 5 is equipped with connecting rod 6, and the inside of connecting rod 6 is provided with movable slot 11, and the inside bottom end sidewall of movable slot 11 is fixedly connected with adjusting spring 12, and adjusting rod 5 is telescopic and inserted in movable slot 11 through the one end of its far away from board 4 of linking, and the one end of adjusting rod 5 in movable slot 11 is fixedly connected on the top end of adjusting spring 12, and the bottom end of connecting rod 6 is fixedly connected with pressing plate 7, and the middle of the opposite sidewall of pressing plate 7 and processing table 1 is provided with inner groove 13, and detachably embeddedly connected with electric heating plate 14 in inner groove 13, and the bottom opening of inner groove 13 is detachably connected with heat conduction flat plate 15, and heat conduction flat plate 15 and electric heating plate 14 mutually adhere.

[0018] As the technical effect of the scheme is: because connecting adjusting spring 12 in movable slot 11, thus can flow out the excess of pressing plate 7 pressing, not directly press dead once, also through adjusting spring 12 can provide motion buffer for the lifting of driven column 9 and flat plate 10, make pressing plate 7 first position bag, then through flat plate 10 to bag and stretch smoothing, finally through the electric heating plate 14 and heat conduction flat plate 15 in pressing plate 7 to bag and heat melting edge processing.

[0019] Specifically, the utility model uses, first place the bag on the processing platform 1, then start telescopic rod 3 and drop the interface board 4, with the interface board 4 drop the pressing plate 7 first and contact with the bag edge, and the interface board 4 continues to drop, when the leveling plate 10 and bag adhere to the pressure generated by the interface board 4 drop drive driven column 9 expands outward, in this way push the leveling plate 10 moves on the bag, this can stretch the bag and flatten, benefit from the pressing plate 7 at this time still not completely press the bag dead, so will not affect the flattening treatment to the bag, finally adjust the rod 5 is inserted into the connecting rod 6 and adjusts the spring 12 to be completely compressed to drive the pressing plate 7 and press the edge of the bag dead, start electric heating plate 14 heating, through the uniform transmission of heat flat plate 15 heat sealing to the bag, after the treatment, through telescopic rod 3 and pull the interface board 4 upward, through the adjusting spring 12 will not immediately leave the bag, with the interface board 4 rises driven column 9 under the processing of torsional spring gradually returns to the original position, finally through the completely stretched adjusting spring 12 and take the pressing plate 7, realize the bag edge sealing treatment.
