Detailed description of the invention
A kind of paper bag trimming mechanism, as shown in Figure 1, comprise paper bag and transmit deviation correcting device and cutter 4, move towards order according to paper bag, before paper bag transmission deviation correcting device is positioned at cutter 4, described paper bag transmits deviation correcting device and comprises transfer roller 1 and deviation rectification roller 2, order is moved towards according to paper bag, before transfer roller 1 is positioned at deviation rectification roller 2, both are axially arranged in parallel, but deviation rectification roller 2 is less than transfer roller 1 height apart from ground level;
Deviation rectification roller 2 is divided into end and middle part, middle part starts from deviation rectification roller 2 center, finally self correction roller 2 center is to two end axles to extension same distance place, middle part cross sectional radius is less than end cross-sectional radius surface, this paper bag transmits paper bag that deviation correcting device can ensure to be surrounded by glue limit and drives to cutter front position and do not occur skew, and if there is skew, it adjustment can also be gone back to tram, make trimming position not occur error, ensure that trimming is accurate.
As shown in Fig. 1,2a, 2b, cutter 4 comprises cutting knife installing rack 3, tool rest 13 and cutting knife 6, and cutting knife installing rack 3 is fixed on bracing frame 5, and cutting knife 6 is in lengthy motion picture shape, and be fixedly mounted on tool rest 13, tool rest 13 is porose, can be sheathed on cutting knife installing rack 3;
Two tool rests 13 that cutting knife 6 is housed are symmetrical sheathed is installed on cutting knife installing rack 3 two ends, and cutting knife 6 pierces through glue limit 8, and point of a knife is positioned at below glue limit 8, and cutting knife blade and paper bag move towards relative.Because glue limit quality is soft, keep tension force in paper bag transport process simultaneously always, make glue limit also keep tension force, be in and tighten straight condition, so along with the movement of paper bag, glue limit is just successfully cut off by cutting knife 6.
Described tool rest 13 is sheathed on cutting knife installing rack 3, can be free to slide, and on tool rest 13, coupling has the trip bolt 7 for dead knife seat 13 position on cutting knife installing rack 3.The distance between two cutting knifes 6 can be adjusted at any time by trip bolt 7, it is made to may be used for the trimming work of plurality of specifications paper bag, simultaneously when not needing to use trimming function, two cutting knife 6 trip bolts 7 can be loosened, cutting knife is changed direction, make it not contact with paper bag and glue limit, then fixed by trip bolt 7.
This paper bag trimming mechanism also comprises tensioner, with reference to shown in Fig. 3, be positioned at below cutter 4, tensioner comprises forward pull roller 11 and backward pull roller 12, forward pull roller 11 and backward pull roller 12 apportion cutter 4 both sides, axially be arranged in parallel with cutter 4, move towards order according to paper bag, before forward pull roller 11 is positioned at backward pull roller 12, both are equal apart from ground level, and forward pull roller 11 moves in the direction of the clock, backward pull roller 12 is by counterclockwise rotating.When the paper bag making to be surrounded by glue limit is like this by tensioner, under the acting in opposition of forward pull roller 11 and backward pull roller 12, stretching better effects if is tightened on paper bag and glue limit, and cutting knife 6 is easier successfully to be cut off glue limit, and otch is neat.
In order to paper bag after ensureing trimming arrives subsequent work position smoothly, this paper bag trimming mechanism is also provided with transfer roller 1, and move towards order according to paper bag, after it is positioned at backward pull roller 12, transfer roller 1 roll shaft is installed on bracing frame 5 by bearing.
In this paper bag trimming mechanism, transfer roller 1, deviation rectification roller 2, forward pull roller 11, backward pull roller 12 are all installed on bracing frame 5 by bearing;
With reference to shown in Fig. 4, power is provided by motor 9, reductor 10 is for reducing rotating speed, motor 9 output shaft is connected by shaft coupling with reductor 10 power shaft, reductor 10 output shaft is connected by shaft coupling with transfer roller 1 roll shaft, and transfer roller, deviation rectification roller, backward pull roller roll shaft rotating in same direction, be in transmission connection by leather belt opening; Forward pull roller, backward pull roller rotate backward, and are in transmission connection by crossbelt.
