Description

Technical Field

[0001] The utility model relates to the technical field of bag cutting machines, in particular to a bag cutting machine which is convenient for cleaning a cutting blade. Background Art

[0002] Woven bags are a common packaging material, generally made of plastic, which is extruded and stretched into flat wires and then woven. During the packaging and transportation process, woven bags are mainly under the gravity of the packaged objects and are always in a tensile state. Due to the criss-cross weaving, woven bags have good tensile resistance and puncture resistance, and will not break easily, so they are widely used.

[0003] Existing woven bags are cut manually, and a long roll of tape is cut into woven bags of specified lengths one by one. This manual bag cutting has low efficiency and high labor intensity. There are also several bag cutting machines on the market. The knife body is usually installed above the woven bag, and the knife body moves up and down, which is easy to cause work-related accidents, and has the disadvantages of complex structure and high cost.

[0004] As disclosed in Chinese patent CN202212989U, this kind of automatic bag cutting machine reduces the intensity of manual labor, reduces the possibility of work-related injuries during labor, improves work efficiency, and reduces the cost of the enterprise.

[0005] However, the bag cutting machine is not provided with a cleaning function, so it is not convenient to clean the woven bag debris attached to the outer side of the cutter.

[0006] For this reason we urgently need to provide a kind of bag cutting machine that is convenient to cutting knife cleaning. Utility Model Content

When the first motor is started and its output shaft rotates to drive the threaded rod to rotate, the movable plate can be driven to slide along the outer side of the limit rod, so that the brush can slide along the outer side of the cutter to clean the outer side of the cutter.

[0012] A further improvement is that a slide groove is vertically provided in the middle of the front and rear ends of the inner side of the support frame, and the outer sides of the front and rear ends of the cutter are slidably connected with the inner side of the slide groove. Therefore, when the output shaft of the telescopic member is started to move and drive the cutter to move, the front and rear ends of the cutter will slide along the inner side of the slide groove, thereby limiting the movement of the cutter.

[0013] A further improvement is that the fixed unit includes a front support plate, a rear support plate, a second motor, a rotating rod and a pressure roller, the front support plate is fixedly connected to the front upper side of the base at a position located at the left and right ends of the support frame, the rear support plate is fixedly connected to the rear upper side of the base at a position located at the left and right ends of the support frame, the second motor is fixedly connected to the rear upper end of the rear support plate, the rotating rod is fixedly connected to the front end of the output shaft of the second motor, and the pressure roller is fixedly connected to the outer side of the rotating rod.

Therefore, when the woven bag roll is slid along the upper side of the base, the pressing roller will be located on the upper side of the woven bag roll and roll, so that the upper left and right ends of the woven bag roll are pressed by the pressing roller, so that the woven bag is cut neatly.

[0015] A further improvement is that a rubber pad is fixedly connected to the outer side of the pressing roller, so that the woven bag roll can be firmly pressed by the rubber pad on the outer side of the pressing roller contacting the upper side of the woven bag roll.

[0016] In summary, the present application discloses a bag cutting machine that is convenient for cleaning the cutting blade.

[0017] This technical solution starts the first motor and rotates its output shaft to drive the threaded rod to rotate, which can drive the movable plate to slide along the outside of the limit rod, so that the bristles slide along the outside of the cutter to clean the outside of the cutter.

[0018] Furthermore, when the woven bag roll is slid along the upper side of the base, the pressing roller will roll on the upper side of the woven bag roll, so that the upper left and right ends of the woven bag roll are pressed by the pressing roller, so that the woven bag is cut neatly.
