The work efficiency is low and there is no bag support component at the bag opening station to cooperate with the bag opening to stably open the bag mouth, and the stability of bag opening and bag feeding is insufficient.

[0017] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0018] like Figures 1 to 4As shown, a double-station bag opening and holding mechanism comprises a bag opening component D1 and a bag holding mechanism D2 which slides transversely and docks at the conveying end of the bag opening component at a double station. The bag opening component comprises a bag opening fixing frame D3 and a bag opening bracket D5 which slides longitudinally on the bag opening fixing frame via a bag opening slide rail D4. An upper bag opening electric cylinder D6 and a lower bag opening air cylinder D7 are vertically arranged opposite to each other in the bag opening bracket. The telescopic ends of the upper bag opening electric cylinder and the lower bag opening air cylinder are both provided with bag opening suction cups D8. A bag opening moving cylinder D9 is fixed on the bag opening fixing frame and is moved by the upper bag opening electric cylinder D6 and the lower bag opening air cylinder D7. It is connected to the bag opening bracket to drive longitudinal sliding; the bag supporting mechanism includes two groups of bag supporting components D10, each of which includes two bag supporting plates D11 arranged in parallel to be connected to the lateral sides of the packaging bag opening. The double-station bag supporting mechanism corresponds to two groups of material discharging and bagging mechanisms, that is, when the first station is at the station docking with the bag supporting mechanism, the second station is docked with one of the material discharging and bagging stations, and then switched horizontally. The reciprocating cycle is convenient for increasing the bagging efficiency. For packaging bags of different specifications, it is only necessary to replace the bag supporting plates to adapt to packaging bags of different specifications.

[0019] In the embodiment of the utility model, the bag-supporting plates are rotatably connected to the bag-supporting base plate D13 via the bag-supporting cranks D12 fixedly connected to the side ends thereof, the middle part of the bag-supporting cranks is rotatably connected to the bag-supporting base plate, and the ends of the bag-supporting cranks away from the bag-supporting plates are hinged to the piston ends of the bag-supporting cylinders D14 to drive the bag-supporting plates to swing in conjunction therewith.

[0020] In the embodiment of the utility model, the bag supporting bottom plate is provided with a bag clamping cylinder D15 at the side end of the bag supporting plate for connecting the packaging bag to the bag supporting plate, and the piston end of the bag clamping cylinder is fixed with a bag clamping silica gel D16 for facilitating clamping.

[0021] In the embodiment of the utility model, the upper surface of the bag supporting bottom plate is provided with a limiting groove D17 for limiting the swinging of the bag supporting plate.

[0022] In the embodiment of the utility model, the lower end of the bag supporting bottom plate is slidably connected to a laterally extending switching slide rail D18 via a plurality of sliders, and the lower end of the bag supporting bottom plate is also provided with a switching cylinder D19 for driving it to slide laterally to switch workstations.

[0023] In the embodiment of the utility model, the bag supporting bottom plate is provided with a bagging detection switch D20 below the bag supporting transfer station, and two groups of notches D21 for detection by the bagging detection switch are correspondingly opened on the bag supporting bottom plate.

[0024] In the embodiment of the utility model, a vacuum generator D22 for driving the bag opening suction cup to suck and release is provided on the bag opening bracket, and the vacuum generator is connected to the bag opening suction cup through a pipeline.

[0025] In the embodiment of the utility model, the feeding end of the bag opening assembly is connected to the feeding deviation correction mechanism, and a bag supporting rod D23 for supporting the packaging bag is arranged between the feeding deviation correction mechanism and the bag opening assembly.

[0026] The working principle of the embodiment of the utility model is as follows: first, the packaging bag is pressed and clamped by the upper bag-opening electric cylinder and the lower bag-opening air cylinder extending toward each other, and the vacuum generator is turned on at the same time, so that the bag-opening suction cup and the corresponding vacuum pipeline form a negative pressure environment in time, and the bag-opening suction cup grabs the surface of the packaging bag on one side after contacting the outer bag. After the bag-opening suction cup grabs the surface of the packaging bag, the lower bag-opening air cylinder is completely retracted, and the upper bag-opening electric cylinder is lifted to the corresponding height as required to achieve bag-opening. After the bag is opened, the packaging bag is moved horizontally by the contraction of the bag-opening moving cylinder and supported by the bag-dragging rod. After it is in place, it is docked to the bag-stretching assembly. At this time, the bag-stretching cylinder of this station contracts to expand the bag-stretching plate to support the two lateral sides of the bag opening, and the bag-clamping cylinder extends to clamp the packaging bag on the bag-stretching plate for lateral transfer. After clamping, the switching cylinder is started to move the bag-stretching assembly of this station horizontally to dock with the material discharging and bag-loading mechanism on this side, and the idle bag-stretching assembly on the other side that has completed bag-loading and material discharging is synchronously moved horizontally to the station docking the bag-stretching assembly, and this cycle is efficient and convenient.

[0027] The utility model is not limited to the above-mentioned best implementation mode. Anyone can derive other various forms of double-station bag opening and supporting mechanisms under the inspiration of the utility model. All equivalent changes and modifications made according to the scope of the patent application of the utility model shall fall within the scope of the utility model.
