Technical Field

The invention relates to the technical field of material bag cutting, in particular to an automatic bag cutting device.

Background

The unpacking machine is mainly used for unpacking various bag products, the semi-automatic unpacking machine mainly used in the past can be operated only by the cooperation of personnel who participate in the processes of unpacking, unloading and the like, and the problems of high labor intensity, low efficiency, easy damage to human bodies, environmental pollution and the like exist. Moreover, these bale breakers are sometimes used to break up products with irritating odors, such as fertilizers like urea, which can cause occupational diseases due to close contact with the human body. Later, several bale breakers, such as spiral breakers, multi-knife breakers, saw blade breakers, etc., were invented.

Most of the existing bag opening machines carry a blade through a rotating shaft to carry out rotary cutting, but the bottom or part of a bag body is only cut through by the structure, and then the bag body is shaken to pour materials, so that the efficiency is relatively low.

In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the invention provides an automatic bag cutting device, which is used for cutting and pouring material bags. This embodiment shows only the structure related to cutting, other structures such as the front end conveying, the rear end containing mechanism and the like are not shown, and these structures not shown can adopt the conventional structure of the prior art, and are not described herein again. The relevant portions of the present invention are described below.

The automatic bag cutting device comprises a feeding mechanism 10, a cutting assembly 20 and a moving mechanism 30, wherein:

the feed mechanism 10 is used to transport the bag 100 to a predetermined cutting location.

The cutting assembly 20 includes a first cutter 21 and a second cutter 22. The upper end of the second cutter 22 is connected to a predetermined position of the body of the first cutter 21, and the second cutter 22 is inclined relative to the first cutter 21.

The moving mechanism 30 can move back and forth on a preset moving track, and a first driver 31 connected with the lower end of the first cutting knife 21 and a second driver 32 connected with the lower end of the second cutting knife 22 are arranged on the moving mechanism 30. The moving mechanism 30 serves as an installation structure of the cutting assembly 20, and moves back and forth on the moving track to drive the cutting assembly 20 to move, so that the first cutting knife 21 and the second cutting knife 22 cut the material bag.

In operation of the present invention, the bag 100 is conveyed to a predetermined cutting position, the cutting assembly 20 is controlled to be lifted, the tip of the first cutter 21 cuts the bag 100, and the second cutter 22 lifts and precuts the bag 100. When the moving mechanism 30 performs the cutting movement, the first driver 31 and the second driver 32 respectively receive control to adjust the angles of the first cutter 21 and the second cutter 22, so that when the cutting assembly 20 performs the cutting action, the second cutter 22 firstly cuts the bottom of the material bag 100, and then the first cutter 21 cuts the upper portion of the material bag 100 until the material bag is cut into two parts. Borrow this, when article density in pocket 100 is great or harder, this application cuts the bottom in advance, makes the material part spill, and reduces first cutting knife 21's cutting resistance greatly, not only protects first cutting knife 21, provides cutting efficiency more greatly.

In a preferred embodiment, the feeding mechanism 10 comprises an inclined conveying structure 11, and the cutting assembly 20 is located below the conveying structure 11 and generally sets the end of the conveying structure 11 to the cutting position.

The conveying structure 11 comprises a plurality of rotatable circular rollers and, due to their inclined arrangement, the pockets 100 will automatically slide to the end, awaiting the cutting action, when they are fed into the high end of the conveying structure 11.

In another embodiment of the present invention, the conveying mechanism 11 is disposed on a frame 40, and the conveying mechanism 11 includes a first conveying member 111 and a second conveying member 112 rotatably connected to the frame 40. Meanwhile, the bottom of the frame body is also provided with a fixing mechanism (not shown) for fixing the material bag when the material bag reaches a preset cutting position. The fixing mechanism can adopt a traditional hook shape, the bending direction faces to two ends of the material bag, and the fixing mechanism can fix the material bag after being inserted into the bag body.

After the material bag 100 is cut, the first conveying member 111 and the second conveying member 112 rotate downward rapidly, so that the material bag port discharges the material downward, and the first conveying member 111 and the second conveying member 112 can rotate upward and downward to shake the cut material bag 100, so that the material is discharged completely.

In another preferred embodiment of the present invention, the first cutter 21 and the second cutter 22 are hinged, so that there can be different adjustment parameters when receiving the control of the first driver 31 and the second driver 32. The first driver 31 and the second driver 32 may be any conventional controllable telescopic mechanism, such as an air cylinder, a hydraulic cylinder, etc.

In summary, the present invention is applicable to the technical field of material bag cutting, and provides an automatic bag cutting device, including: the feeding mechanism is used for conveying the material bag to a preset cutting position; the cutting assembly comprises a first cutting knife and a second cutting knife, the upper end of the second cutting knife is connected to a preset position of the first cutting knife body, and the second cutting knife is obliquely arranged relative to the first cutting knife; the moving mechanism can move in a reciprocating mode on a preset moving track, and a first driver connected with the lower end of the first cutting knife and a second driver connected with the lower end of the second cutting knife are arranged on the moving mechanism. Therefore, the material bag cutting machine can cut material bags efficiently, and discharges materials thoroughly.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
