Detailed Description
The present application is further described below with reference to the accompanying drawings.
A bag opening mechanism of a bag feeding type liquid health care product packaging machine as shown in fig. 1 to 6 comprises a bag opening mechanism 10 and a bag bottom opening mechanism 20;
the bag opening mechanism 10 comprises two bag opening pieces 101 which are inserted into the packaging bag through the bag opening of the packaging bag 30 to open the bag opening of the packaging bag;
the bag bottom pulling mechanism 20 comprises a base 201, a driving cylinder 202, a linkage mechanism and two vacuum chucks 203;
the two vacuum chucks 203 are slidably mounted on the base 201, each vacuum chuck is connected with a vacuum generator (not shown in the figure) through a soft air pipe respectively, so that the vacuum chucks can generate negative pressure suction force, the vacuum generator adopts the prior art, the two vacuum chucks 203 are separated at two sides of the packaging bag 30, the two vacuum chucks 203 are positioned at the bottom of the packaging bag, each vacuum chuck is used for adsorbing the film wall of the packaging bag at the same side as the vacuum chuck, and the two opposite film walls of the packaging bag are pulled apart when the two vacuum chucks relatively move away from each other, so that the bottom of the packaging bag is opened;
the linkage mechanism is arranged between the telescopic piston rod of the driving cylinder 202 and the two vacuum chucks 203, so that the driving cylinder 202 drives the two vacuum chucks 203 to synchronously move in a relatively far-away mode or a relatively near-to mode.
This technical scheme is jointly used through the bag bottom mechanism that pulls open and is jointly opened the mechanism to open the sack and the bottom position of wrapping bag, can ensure the degree that the wrapping bag was opened, ensure the loading of wrapping bag.
Through the link gear that sets up not only can make two vacuum chuck simultaneous movement so that adsorb and pull open the bottom of wrapping bag, only need adopt one drive cylinder can realize driving two vacuum chuck moreover, need not to adopt two drive cylinders, can save the power supply, simplify the structure, reduce cost.
The linkage mechanism comprises a lifting push rod 204 and two groups of movable components;
each movable assembly comprises a sliding seat 205, a first connecting rod 206, a pin shaft 207 and a second connecting rod 208;
the two vacuum chucks 203 are respectively installed on a sliding seat 205 of a group of movable components;
in each movable assembly, the sliding seat 205 is slidably mounted on the base 201, so as to realize that the vacuum chuck 203 is slidably mounted on the base 201, one end of the first connecting rod 206 is hinged on the base 201, one end of the second connecting rod 208 is hinged on the sliding seat 205, the other end of the first connecting rod 206 is hinged with the other end of the second connecting rod 208 through a pin shaft 207, and the connecting rod mechanism is composed of the first connecting rod, the pin shaft and the second connecting rod;
