Embodiment 1

[0031] Such as figure 1 As shown, a gravity type soft bag unpacking machine includes a chute 2 with the right end inclined downward, two blades 4 respectively penetrating through the two side walls of the chute 2, and a blade 4 horizontally arranged at the lower right end of the chute 2. The cutter 9 at the feed opening, the angle between the chute 2 and the horizontal direction is 45 degrees.

[0032] The side walls of the chute 2 are provided with longitudinal first gaps 5 at the positions corresponding to the blades 4, and the two blades 4 are symmetrically arranged on the two side walls of the chute 2, and the two blades 4 are respectively arranged on the corresponding Inside the first gap 5. The blades of the two blades 4 are all inward, and the outer walls on both sides of the chute 2 are welded with a rectangular knife seat 3 below the blade 4, and the blade 4 is provided with a strip-shaped through hole consistent with the direction of the blade 4. Screws for fixedly...

Embodiment 2

[0042] Such as figure 2 and image 3 As shown, a gravity type soft bag unpacking machine includes a chute 2 with the right end inclined downward, two blades 4 respectively penetrating through the two side walls of the chute 2, and a blade 4 horizontally arranged at the lower right end of the chute 2. Cutter 9 at the material opening.

[0043]The side walls of the chute 2 are provided with longitudinal first gaps 5 at the positions corresponding to the blades 4, and the two blades 4 are symmetrically arranged on the two side walls of the chute 2, and the two blades 4 are respectively arranged on the corresponding Inside the first gap 5. The blades of the two blades 4 are all inward, and the outer walls on both sides of the chute 2 are welded with a rectangular knife seat 3 below the blade 4, and the blade 4 is provided with a strip-shaped through hole consistent with the direction of the blade 4. Screws for fixedly connecting the blade 4 with the corresponding knife seat 3 ...

Embodiment 3

[0056] Such as Figure 5 and Figure 6 As shown, the difference between this embodiment and embodiment 2 is:

[0057] 1. A window is opened in the middle part of the cover plate 7 near the blade 4, and a negative pressure bag taking device 13 fixedly connected to the frame 1 is arranged above the window;

[0058] 2. Two transverse through holes are opened at the bottom of the chute 2 close to the blade 4, and a closed negative pressure box 11 is welded at the bottom of the chute 2 at the position of the through hole, and the negative pressure box 11 passes through the pipeline Connected to the suction device.

[0059] The negative pressure bag taking device 13 includes a vertical guide tube 1301, the bottom of the guide tube 1301 is a bell mouth facing the window, the center of the guide tube 1301 is provided with a vertical suction pipe 1303, and the suction pipe 1303 is connected to the guide tube. There are gaps between the tubes 1301 . The middle part of the guide pipe...

Abstract

The invention discloses a gravity type soft bag unpacking machine. The unpacking machine comprises an obliquely-placed sliding groove, a blade fixedly arranged on the side wall of the sliding groove and used for cutting the side face of a soft bag, and a cutter arranged at a discharging opening in the lower end of the sliding groove and used for cutting the end face, close to the discharging opening, of the soft bag; and the cutter is vertically arranged between the two side walls of the sliding groove, the cutter is parallel to the bottom face of the sliding groove, the cutting edge of the cutter faces the incoming direction of the soft bag, and the distance between a blade and the bottom of the sliding groove is equal to the distance between the cutter and the bottom of the sliding groove. By using the unpacking machine, the labor intensity of an operator is reduced, scattering and dust raising in the material feeding process are reduced, waste is reduced, the body health of the operator is not affected, and the phenomenon that the hands of the operator are cut is avoided.

Description

technical field [0001] The invention relates to the technical field of feeding equipment, in particular to a gravity type soft bag unpacking machine. Background technique [0002] Soft bags are usually used for the packaging of powdery or granular materials. The types of soft bags include woven belts, kraft paper bags, plastic bags and so on. During production, it is first necessary to break open the soft bag, and then put the materials in it into the production equipment. The usual method of operation is to transport the soft bag containing the material to the material inlet of the production equipment manually or by using a forklift, flatbed truck, etc., and then the operator manually cuts the soft bag with a blade, and finally pours the material into the material inlet. . The labor intensity of the operator is high, and the soft bag will inevitably be scattered and dusted in the process of material delivery after cutting, which not only causes waste, but also affects th...
