[0018] In order to comprehensively disclose the utility model, the technical scheme of the utility model will be specifically described below in combination with the drawings and examples. In the description of the utility model, Figure 1 The left side of the front face is the front face of the utility model, Figure 1 The upper and lower sides of the front face are the upper and lower directions of the utility model.

[0019] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 : two guide rails 2 are installed on the frame 1, the two guide rails 2 are installed in parallel, one sliding block 3 is installed on each guide rail 2, and a connecting piece 7 is installed on the sliding block 3; an opening cylinder 4 is installed in the left and right directions of the middle position of the front and back of the connecting piece 7, the tail of the opening cylinder 4 is installed on the frame 1, and from the perspective of top view, as shown in Figure 3 , from the perspective of bottom view, as shown in Figure 4 .As shown; a support plate 5 is installed downwards at both ends of the right side of the connector 7. The two support plates 5 on the left side form a group. The group of support plates on the left side can move left and right along the two guide rails 2 under the drive of the opening cylinder 4. This is the "support plate 5 connected to the slider 3" described in the technical solution of this utility model. A clamping hole 51 is provided at the lower part of each support plate 5. A guide rod cylinder 6, also known as a three-axis cylinder, is installed on the left side of the connector 7. A rubber pad 62 is provided and installed on the cylinder rod seat of the guide rod cylinder with an internal hex screw, so that the installation position of the internal hex screw corresponds left and right to the clamping hole 51 on the support plate 5. When the clamping cylinder 6 is opened, the round head of the internal hex screw can extend into the clamping hole 51, which can act as the protrusion 61. The internal hex screw can be referred to as the protrusion 61; a connector 7 is also installed on the right end of each of the two guide rails 2, and a support plate 5 is installed on the left end of the connector 7 (or the two support plates 5 can be installed on the frame 1 respectively), thus forming a set of support plates on the right side. This is the support plate 5 connected to the guide rail 2 as described in the technical solution of this utility model; the left and right sets of support plates correspond to each other, and a clamping cylinder 6 is also installed on the lower right end of the connector 7. A rubber pad 62 is also installed on the cylinder rod seat of the two clamping cylinders 6 with an internal hex screw. The protruding part of the internal hex screw from the head of the rubber pad 62 forms the protrusion 61. A clamping hole 51 is also provided at the position of the support plate 5 corresponding to the protrusion 61, thus forming multiple (4) clamping areas.

[0020] The specific working process of the embodiment is as follows: Figure 5 Figure 6 As shown, in the initial state, the cylinder rod of the expanding cylinder 4 extends to the right, and the relative distance between the left and right sets of support plates 5 is small. Then, the opening of the woven bag 8 is placed on the four support plates 5. After that, the solenoid valve (not shown in the figure) controls the expanding cylinder 4 to release, thereby driving the left set of support plates 5 to move to the left, opening the woven bag 8 and forming the opening as shown in the figure. Figure 5 As shown in the diagram; then all four clamping cylinders 6 are fully opened. The protrusions 61 of the opened clamping cylinders 6 press the woven bag 8 into the clamping holes 51 of the support plate, and the cylinder rod seat and rubber pad 62 simultaneously clamp the opening of the woven bag 8 onto the support plate 5, forming a state as shown. Figure 6In the shown state, when the clamping cylinder 6 clamps the bag opening position of the woven bag 8, the impact force on the woven bag 8 and the supporting plate is attenuated due to the buffering and damping effect of the rubber pad 62, the noise is low, and the clamping force is increased. Thus, the working steps of the utility model are completed. Because the bag opening position of the woven bag 8 is expanded by the four supporting plates 5, and the four clamping cylinders 6 clamp the woven bag 8 on the supporting plate 5, the bag opening position of the woven bag 8 forms four clamping areas, which are equivalent to four clamping fixing points, so that the woven bag 8 can be stably sleeved and hung on the supporting device, and under the same conditions, the pulling force of the expanding cylinder 4 can be relatively reduced, and the phenomenon that the woven bag 8 is expanded and damaged can be avoided; and the four clamping points formed between the supporting plate 5 and the clamping cylinder 6 form a square, which corresponds to the external contour of each layer of plastic bags to be loaded, so that the loading work is smooth.
