Problems solved by technology

[0002] In the design of the fruit bagging device, when the bag is conveyed in place, it is necessary to open the bag immediately to facilitate the insertion of the fruit. Adhesive or negative pressure is used to adsorb the bag mouth, but the adsorption is not reliable, and it is not easy to damage the bag when it is loosened. The negative pressure is generally electric, but most of them do not have power at the operation site, so it is difficult to implement. Therefore need a kind of mechanical negative pressure adsorption mechanism now

Embodiment Construction

[0030] The present invention is described in further detail below in conjunction with accompanying drawing:

[0031] Such as figure 1 As shown, the cam 2 is in contact with the side of the piston support plate 16, and the side of the piston support plate 16 is provided with a piston spring 15. The piston spring 15 always gives the piston support plate 16 a force in the direction of the cam 2, so that the piston rod 17 always contacts the cam. 2 peripheral surfaces, one side of the piston support plate 16 is hinged with a runner 14 through a support rod, the runner 14 is in contact with the cam 2, and the other end of the piston support plate 16 is connected to four piston rods 17, and the four piston rods 17 are respectively arranged on four One end of four cylinders 19 inside, the other end of four cylinders 19 is respectively connected two upper suction cups 5 and two following suction cups 10 by negative pressure pipe 20.

Abstract

The invention discloses a negative-pressure adsorption formation control mechanism and a bag opening device using the same. The negative-pressure adsorption formation control mechanism comprises a movable arm, a cam, a first pulley, a second pulley, an upper sucking disc and a ratchet mechanism. The negative-pressure adsorption formation control mechanism and the bag opening device disclosed by the invention have the beneficial effects that in the lifting process of the movable arm, a ratchet drives the cam to rotate, the cam drives the second pulley to rotate by driving the first pulley, thesecond pulley rotates to drive the upper sucking disc to fall off by a distance adjusting mechanism, a piston rod pushes a piston, the upper sucking disc and a lower sucking disc exhaust, the piston rod retracts the piston to form negative pressure after the cam rotates by a circle, the upper sucking disc and the lower sucking disc adsorb a bag, and the upper sucking disc returns to the original position, so that the opening of the bag can be realized only by one-time lifting action, the bagging steps are simplified and the bagging efficiency is improved.

Description

technical field [0001] The invention belongs to the field of fruit bagging, and relates to a negative pressure adsorption formation control mechanism and a bag opening device using the mechanism. Background technique [0002] In the design of the fruit bagging device, when the bag is conveyed in place, it is necessary to open the bag immediately to facilitate the insertion of the fruit. Adhesive or negative pressure is used to adsorb the bag mouth, but the adsorption is not reliable, and it is not easy to damage the bag when it is loosened. The negative pressure is generally electric, but most of them do not have power at the operation site, so it is difficult to implement. Therefore need a kind of mechanical negative pressure adsorption mechanism now. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a negative pressure adsorption formation control mechanism and a bag open...
