The mold frame shown in fig. 1 and 2 is in a state in which the mold frame 2 is formed after swinging backward by the driving of the swing cylinder. The above technical contents belong to the known technologies and are disclosed in the reference 1, and are not described herein again.

Two linear guide rails 33 are arranged in parallel at the position of the frame 1 at the rear lower part of the mould frame 2, and two sliding blocks 34 are respectively installed on the two linear guide rails 33 in a sliding way; a bracket 32 is arranged, the bottom surface of the bracket 32 is arranged on a sliding block 34, two sides of the bracket 32 are respectively provided with an air cylinder 31, the cylinder rod of the air cylinder 31 is connected to the frame 1, and the bracket 32 can be driven to reciprocate back and forth relative to the mould frame 2 when the air cylinder 31 works; throttle valves are arranged on an air inlet and an air outlet of the air cylinder 31, and the speed of the backward movement of the air cylinder is adjusted to be lower than the speed of the backward movement of the bag discharging rod 21 pushed by the electric sliding table 22; an L-shaped supporting plate 3 is arranged, the supporting plate 3 can be bent into a right angle by a rectangular flat plate, the vertical part is a vertical plate and corresponds to the bag bottom of the packaging bag, and the transverse part is a transverse plate part and corresponds to the side surface of the packaging bag; or a vertical plate can be vertically welded on the rear side of a flat plate to form an L-shaped state; a rotating shaft is arranged below the rear end of the supporting plate 3, and two ends of the rotating shaft are rotatably connected to the bracket 32; a cylinder 35 is connected between the bracket 32 and the supporting plate 3, and when the cylinder 35 works, the supporting plate 3 can be driven to swing back and forth relative to the bracket 32; a rotating shaft 41 is rotatably arranged below the front end of the supporting plate 3, two stop rods 4 are arranged on the rotating shaft, the stop rods 4 correspond to gaps between the stop rods of the mold frame 2 and correspond to the bag discharging rods 21 in a staggered manner, a rocker arm 42 is arranged at one end of the rotating shaft 41, the other end of the rocker arm 42 is connected with a cylinder 43, and the other end of the cylinder 43 is connected to the bracket 32.

The working process of the first embodiment is as follows: as shown in fig. 3 to 6: after the plastic bag is filled in the mold frame 2, the packing bag 5 is put on the mold frame, and the state shown in fig. 3 is formed after swinging. Thereafter, the air cylinder 31 opens to drive the bracket 32, the pallet 3, and the like to move forward along the linear guide 33 until the vertical plate portion of the pallet 3 abuts against the bottom of the packaging bag 5, resulting in the state shown in fig. 4. After that, the electric sliding table 22 is opened to drive the bag arranging rod 21 to move backwards, the bag mouth end of the packing bag 5 and the plastic bag in the mold frame 2 are pushed backwards together during the backward movement of the bag arranging rod 21, the air exhausting speed of the air cylinder 31 is slow, and when the electric sliding table 22 drives the bag arranging rod 21 to push the plastic bag backwards, the plastic bag forms a certain squeezing and clamping force between the bag arranging rod 21 and the supporting plate 3, and the squeezing and clamping force enables the plastic bag to be gradually pressed into the packing bag 5. With the continuous pushing of the electric sliding table 22, the supporting plate 3 also moves backwards slowly, so that the bag body part of the packaging bag 5 is gradually and horizontally placed on the transverse plate part of the bag supporting plate 3, when the bag opening position of the packaging bag 3 is about to be separated from the mold frame 2, the air cylinder 43 opens the driving rocker arm 42, the rotating shaft 41 and the blocking rod 4 to swing backwards together, and the blocking rod 4 can pass through the gap of the mold frame 2 and swing upwards by staggering the bag discharging rod 21 until the blocking rod 2 stands upright to block the bag opening position of the packaging bag 5, so that the plastic bag at the bag opening position is prevented from scattering; after the bag discharging rod 21 stops moving, the air cylinder 31 continues to drive the pallet 3 backward for a distance again, and the state shown in fig. 5 is formed. Then, the air cylinder 35 opens and drives the supporting plate 3 to carry the packing bag 5 filled with the plastic bag to swing backwards together, and stops when the packing bag 5 swings to be close to the upright state, then the bag arranging rod 21 moves forwards and resets under the driving of the electric sliding table 22, the air cylinder 43 releases, the blocking rod 4 swings and resets, the mouth of the packing bag 5 filled with the plastic bag faces upwards and stands on the supporting plate 3, and the operator waits for taking the packing bag away, so that the state shown in fig. 6 is formed, and the working steps of the first embodiment are completed.

The second embodiment is mainly different from the first embodiment in that: as shown in fig. 7, the mold frame is in an inclined state during bag arrangement, the support plate moving mechanism is an electric sliding table 36, the bracket in the first embodiment is omitted, the support plate 3 is an I-shaped upright vertical plate, the support plate 3 is connected to a slide 261 of the electric sliding table 26, and the electric sliding table 26 is mounted on the frame 1. The working process of the second embodiment is as follows: when the plastic bag is loaded into the bag from the mold frame 2 backwards by the telescopic supporting rod or other bag arranging mechanism, the electric sliding table 36 makes the supporting plate 3 support the bag bottom position of the bag through the sliding table seat 361, and then slowly moves backwards, when the bag is separated from the mold frame 2, one side of the bag, namely the bottom surface, is supported by the frame 1 in an inclined state, and the bag bottom is supported by the supporting plate 3. Because the packaging bag is inclined upwards, the plastic bag cannot fall off from the opening of the bag, and the inclined state is convenient for an operator to take the packaging bag away.
