The air guide sleeve seat 1b is connected with each first horizontal bag supporting cylinder 2a and each second horizontal bag supporting cylinder 2e on the pneumatic bag supporting mechanism 2 corresponding to the blanking hole 1a in a conduction mode through an air supply pipe.
In the initial state, the pneumatic bag opening mechanism is in a bag opening state, and the first horizontal bag opening cylinder 2a and the second horizontal bag opening cylinder 2e are in a contraction state.
When the lifting type air supply mechanism 3 descends to inflate the air guide sleeve seat 1b, the first horizontal bag opening cylinder 2a and the second horizontal bag opening cylinder 2e respectively extend out, and the first pull rod 2c and the second pull rod 2g are close to each other and are folded; when the lifting type air supply mechanism 3 rises to be separated from the air guide sleeve seat 1b, the first pull rod 2c and the second pull rod 2g are in a bag supporting state under the action of the corresponding first return spring 2d and the second return spring 2 h.
In this embodiment, the first level props the shrink state that a bag cylinder and second level propped a bag cylinder, is to restore to the throne the completion by the pulling of the reset spring elasticity that corresponds, and this kind of mode props the bag through the elasticity of spring, has the advantage that the dynamics is soft when propping the bag firm, strutting. If the air cylinder is adopted for bag opening, the requirements on air pressure and air cylinder stroke precision are extremely high, and the manufacturing cost is high. The utility model adopts the spring elastic force to support the bag, thereby skillfully and simply realizing the function.
Further preferably, the lifting air supply mechanism 3 comprises an air supply bracket 3a, and the air supply bracket 3a is movably connected with the rotating shaft of the turntable 1 through a bearing; an air supply lifting cylinder 3b is arranged on the air supply support 3a along the vertical direction, the free end of a piston rod of the air supply lifting cylinder 3b is connected with an air supply connector 3c matched with the air guide sleeve seat 1b, and the air supply connector 3c is connected with an external compressed air source pipeline.
The gas supply bracket 3a is connected with a reciprocating swing assembly, and the gas supply bracket 3a reciprocates between preset stations under the action of the reciprocating swing assembly.

When the air supply support 3a is contacted with the limiting column, the third reset spring 4 is in a micro-tensioning state, the air supply connector 3c is opposite to and contacted with the air guide sleeve seat 1b on the side edge of the output station, when the blanking hole 1a positioned on the output station rotates to the bag opening station, the air supply connector 3c is separated from the air guide sleeve seat 1b, and the third reset spring 4 drives the air supply support 3a to reset.
Through the third return spring, the reciprocating swing of the lifting type air supply mechanism between the two stations can be ingeniously solved.
Further preferably, the lower ends of the first pull rods 2c are located at the lower sides of the lower ends of the second pull rods 2g, and when the bag is opened, the two first pull rods 2c are located at the two ends of the opening portion of the packaging bag along the width direction, and the two second pull rods 2g are located at the two sides of the middle portion of the opening portion of the packaging bag along the width direction. Meanwhile, the first pull rod 2c is a single pull rod vertically arranged on the first connecting seat 2 b; the second pull rod 2g is a double-pull rod vertically arranged on the second connecting seat 2f and arranged at intervals.
According to the structure, when the packaging bag is sleeved, the packaging bag can be driven to move downwards by the gravity when the pomelo fruits enter the packaging bag, so that the packaging bag is separated from the second pull rod and keeps in contact with the first pull rod, and the effect of flatly opening the bag opening of the packaging bag in the width direction is formed, so that the subsequent welding of a welding station is facilitated. Has the advantages of simple and ingenious structure.
Referring to fig. 4, the turntable is fixed on the frame, and four blanking holes on the turntable correspond to the bag opening station, the bag sleeving station, the weld crater station and the output station respectively.
An automatic bag supply device 5 is arranged at the bottom of the bag opening station, and an automatic grapefruit conveying device 6 is arranged on the side edge of the bag sleeving station. When the pomelo is bagged, the packaging bag is unfolded by the pneumatic bag opening mechanism at the bag unfolding station, then the bagging is carried out at the bagging station, and when the bagging is carried out, the packaging bag falls to the bottom sliding groove under the driving of the gravity of the pomelo and is separated from the second pull rod and keeps in contact with the first pull rod. Then, the packaging bag is rotated to a welding port station for welding through the rotation of the rotary table. And finally, the material is output from the output station through the rotation of the turntable. During output, the lifting type air supply mechanism descends, compressed air is supplied to the pneumatic bag opening mechanism of the output station to enable the air cylinder to extend out, the first pull rod and the second pull rod are in a mutually folded state, and the packaging bag falls off. The lifting type air supply mechanism is kept still, the turntable drives the lifting type air supply mechanism to rotate together, and therefore the packaging bags can be conveniently sleeved, and after the bagging is completed. The lifting type air supply mechanism rises, and the pneumatic bag opening mechanism is in an automatic bag opening state under the action of the corresponding return spring. Meanwhile, the lifting air supply mechanism is reset to be opposite to the air guide sleeve seat of the output station under the action of a third reset spring.
The above embodiment is the preferred embodiment of the present invention, which is only used to facilitate the explanation of the present invention, it is not right to the present invention, which makes the restriction on any form, and any person who knows commonly in the technical field can use the present invention to make the equivalent embodiment of local change or modification without departing from the technical features of the present invention.
