Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, a bag-preparing chain tensioning mechanism of an automatic packaging machine comprises a tensioning mechanism 8 installed on a single driven sprocket 2, the driven sprocket 2 is fixed on a rack through a sprocket mounting plate 7, a sliding groove 9 parallel to a chain 4 is formed in the sprocket mounting plate 7, the tensioning mechanism 8 comprises a tensioning slide block 13 connected to the sliding groove 9 in a sliding manner, the driven sprocket 2 is connected with the tensioning slide block 13 through a center bearing, and the chain 4 is tensioned by moving the tensioning slide block 13 to adjust the distance between the driven sprocket 2 and a driving sprocket 1. Three groups of bag preparing chains of the automatic packaging machine are arranged, the number of the driving chain wheels 1 and the driven chain wheels 2 is equal to that of the chains 4, the driving chain wheels 1 are arranged on a driving wheel shaft 3, the end part of the driving wheel shaft 3 is also provided with a driving wheel 5, the driving wheel 5 is driven by a belt and a driving wheel on a motor 6, so that the driving wheel 5 is driven by the motor 6 to rotate, the whole driving wheel shaft 3 rotates, thereby driving the chains 4 to convey the packaging bag stack, when one of the chains 4 is loosened, the corresponding driven chain wheel 2 can be tensioned by the tensioning mechanism 8, thus, the other normal chains 4 are not influenced, the adjustment is easy, and the driven chain wheel 2 is tensioned independently, even if this be equipped with bag chain assembly is at the assembled, there is machining error in keyway, driving shaft keyway or driven shaft keyway etc. of each sprocket, also can guarantee each chain 4 normal use through the tensioning degree of adjusting every sprocket.

As shown in fig. 2, the manner of adjusting the tension of the chain 4 by the tension mechanism 8 is as follows: by adjusting the movement of the tensioning slider 13 on the sliding groove 9, the driven sprocket 2 is moved away from the driving sprocket 1 to tension the chain 4.

As shown in fig. 3, the tensioning mechanism 8 further includes a fixed seat 10, a screw rod 11 is vertically mounted on the surface of the fixed seat 10 through a bearing seat 14, the screw rod 11 penetrates through a tensioning slider 13, a thread groove is formed in the tensioning slider 13, the tensioning slider 13 is moved by rotating the screw rod 11, the tensioning slider 13 and the screw rod 11 are relatively rotated by rotating the screw rod 11, and the tensioning slider 13 is in threaded connection with the screw rod 11 and is limited to horizontally slide in the sliding groove 9, so that the screw rod 11 can be driven to translate in the sliding groove 9. Sliding tray 9 is equipped with two and is parallel to each other, and driven sprocket 2 is located between two sliding trays 9, and tensioning slider 13 on every sliding tray 9 all adjusts through a lead screw 11, and two tensioning sliders 13 and sliding tray 9 make 2 both sides atress of driven sprocket even, consequently need adjust lead screw 11 simultaneously when adjusting tensioning slider 13 and remove and adjust, and lead screw 11 keeps away from the one end installation nut cover 12 of bearing frame 14, and nut cover 12 is used for facilitating the use if: the screw rod 11 is rotated by tools such as a wrench, a screwdriver and the like, so that the tensioning mechanism 8 is more convenient to adjust.
