[0050] The horizontal packaging bag unloading mechanism provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in combination with the accompanying drawings.

[0051] Embodiment 1:

[0052] like Figures 1 to 2 As shown, an embodiment of the present application provides a horizontal packaging bag unloading mechanism, including a frame 1 on which a conveyor belt 2 is installed; and a bag grabbing and transferring device, which can be movably installed on the frame 1 and is used to transfer the external packaging bag to the conveyor belt 2.

[0053] Furthermore, the bag grabbing and transferring device comprises a grabbing unit 3 for grabbing the external packaging bag; and a moving unit 4 for enabling the grabbing unit 3 to move along the conveyor belt 2 .

[0054] Preferably, a pair of grabbing units 3 are provided.

[0055] Furthermore, the grabbing unit 3 includes a cylinder 31, which is fixedly mounted on the moving unit 4; a pair of baffles 32, fixedly connected to both sides of one end of the cylinder 31 with a piston rod; a pair of clamping plates 33, hinged between the pair of baffles 32, and transmission-connected to the outer end of the piston rod.

[0056] Furthermore, the clamping plate 33 includes an L-rod 331, whose bending part is hinged to a pair of baffles 32 through a hinge shaft; a clamping plate 332, which is fixed to the outer end of the L-rod 331 by bolts, and the other end of the L-rod 331 is hinged to the outer end of the piston rod.

[0057] Furthermore, the clamping plate 33 further includes an anti-slip strip 333 , which is installed on the inner surface of the baffle plate 32 by means of bolts.

[0058] In this embodiment of the present application, due to the adoption of the above-mentioned structure, a pair of gripping units 3, under the control of the moving unit 4, approach the external horizontal vacuum packaging machine, a pair of cylinders 31 operate, and their respective piston rods retract, driving each L rod 331 to flip around the corresponding hinge axis, so that a pair of clamps 33 approach each other, clamping the vacuumed and heat-sealed packaging bag between each pair of anti-slip strips 333, and the moving unit 4 operates in the reverse direction, dragging each cylinder 31 away from the external horizontal vacuum packaging machine, and accordingly, the packaging bag is dragged out of the external horizontal vacuum packaging machine, and after the bottom of the packaging bag contacts the top of the conveyor belt 2, the piston of each cylinder 31 extends out, pushing and driving each L rod 331 to flip around the corresponding hinge axis, so that the pair of clamps 33 move away from each other, and the packaging bag falls onto the conveyor belt 2 under the action of gravity, completing the unloading, and the pair of cylinders 31, under the control of the moving unit 4, approach the external horizontal packaging machine again to perform the next unloading action;

[0059] A through hole is provided at one end of each L-rod 331 away from the clamping plate 332, and is hinged to the outer end of the corresponding piston through a rotating shaft. Since each L-rod 331 flips around the corresponding hinge shaft, the overlapping range of the through holes of each L-rod 331 will change. The diameter of each through hole is larger than the corresponding hinge shaft, thereby preventing a pair of adjacent L-rods 331 from being obstructed by the hinge shaft when rotating around the corresponding hinge shaft.

[0063] In this embodiment of the present application, due to the adoption of the above-mentioned structure, by rotating the screw rod 72, the two ends of each screw rod 72 are raised and lowered in the corresponding upper screw holes and lower screw holes 71, or by replacing the screw rods 72 of different lengths, the vertical spacing between the lifting plate 6 and the fixed plate 5 is adjusted to achieve the purpose of adjusting the height of the bag grabbing transfer device, so that it can adapt to external horizontal vacuum packaging machines of different heights.

[0064] Embodiment 3:

[0065] like Figure 3As shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, the moving unit 4 includes a pair of pulleys 41, which are respectively rotatably installed at both ends of the top of the lifting plate 6; a sliding plate 42, which is slidably installed at the top of the lifting plate 6; a transmission belt 43, which is installed on the pair of pulleys 41 in a transmission manner, and one side is fixedly connected to the sliding plate 42, and any one of the pulleys 41 is driven to rotate by a motor.

[0066] Furthermore, the moving unit 4 further includes: a pair of slide rails 44, which are fixedly arranged at the top end of the lifting plate 6; a pair of sliders 45, which are fixedly arranged at the bottom of the sliding plate 42 and are respectively slidably installed on the respective slide rails 44.

[0067] In this embodiment of the present application, due to the adoption of the above structure, the motor drives one of the pulleys 41 to rotate, causing the transmission belt 43 to rotate on the pair of pulleys 41, driving the sliding plate 42 to slide along the pair of slide rails 44, so that the pair of cylinders 31 fixedly connected to the sliding plate 42 move together with the sliding plate 42, so as to achieve the purpose of controlling the cylinders 31 to approach / away from the external horizontal vacuum packaging machine.
