Description

A cutting device with blowing device

technical field

The utility model relates to a packaging machine, in particular to a cutting device with an air blowing device.

Background technique

With the development of science and technology, the mechanized bag making machine has gradually become a necessary product in every industry. When dividing into individual bags, a cutting device is needed. At present, when the cutting device in the packaging machine cuts the bag, it can only pass through the rear The conveying roller of the bag is sent forward, and the edge of the bag sometimes tilts up or turns over. Because it is an assembly line operation, it will cause mis-cutting, and many defective products will be formed, wasting costs and delaying production efficiency. At the same time, the existing The cut-off device just cannot be used once the cylinder or the point machine break down, and the practicability is poor.

Utility model content

The purpose of this utility model is to solve the problems in the prior art, and propose a cutting device with an air blowing device, which can press down the bag with airflow through the blowing device, is not easy to roll over, and can be used manually, with strong practicability.

In order to achieve the above object, the technical scheme that the utility model takes is:

A cutting device with an air blowing device, comprising a cutting knife and a wall panel, the cutting knife includes an upper knife and a lower knife, and several air cylinders are arranged on the top of the upper knife, and the air cylinders are fixed on a beam, and the beam is composed of A plurality of sleeves are socketed, the sleeves are directly provided with fixed buckles, the two ends of the upper knife are symmetrically provided with guide wheels, the wallboard is provided with guide grooves, and the guide wheels cooperate with the guide grooves. The back of described cutting knife is provided with air-blowing device, and described air-blowing device comprises air-blowing pipe and horizontal pipe, and described air-blowing pipe one end is connected with the middle part of horizontal pipe, and described horizontal pipe is evenly distributed with some through holes, so An internal thread is provided in the through hole, and an air blowing head is threadedly connected to the through hole.

Preferably, a sealing plug is threadedly connected to the through hole.

Preferably, a handle is provided on the beam.

Preferably, one end of the blowing pipe is threadedly connected with an air outlet of a blower.

The utility model has a simple structure, can press down the bag with the airflow through the air blowing device, is not easy to turn over, improves the yield, improves the production efficiency, saves the cost, and can be used manually at the same time, with strong practicability.

Detailed ways

In order to make the purpose and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Figures 1-3, this specific embodiment adopts the following technical solutions: a cutting device with an air blowing device, including a cutting knife 1 and a wallboard 2, the cutting knife 1 includes an upper knife 1.1 and a lower knife 1.2, the The top of the upper knife 1.1 is provided with a number of cylinders 4, and the cylinders are fixed on the beam 5. The beam 5 is formed by socketing a number of sleeves, and the sleeves are directly provided with fixed buckles. The two ends of the upper knife 1.1 A guide wheel 3 is symmetrically arranged, and a guide groove 2.1 is provided on the wallboard, and the guide wheel 3 cooperates with the guide groove 2.1, and an air blowing device 6 is provided behind the cutting knife 1, and the air blowing device 6 includes Air blowing pipe 6.1 and horizontal pipe 6.2, one end of the air blowing pipe communicates with the middle part of the horizontal pipe 6.2, a number of through holes are evenly distributed on the horizontal pipe 6.2, internal threads are provided in the through holes, and internal threads are arranged in the through holes. The threaded connection has a blowing head 6.3.

A sealing plug is threadedly connected to the through hole.

A handle is provided on the beam 5 .

One end of the blowing pipe 6.1 is threadedly connected with an air outlet of a blower.

During use, the continuous bag is pushed forward by the conveying roller at the back, passes through the air blowing device 6, the airflow presses down on the bag, and goes through a stroke of a bag length, the cutting knife 1 moves, the upper knife 1.1 goes down, cuts the bag, and then Go through a bag-length stroke, cut off again, and repeat. The utility model has a simple structure, and the bag can be pressed down by the airflow through the air blowing device 6, and it is not easy to roll over. The distance between them can be manually lifted and pressed to drive the upper knife 1.1 to move back and forth for cutting, which is highly practical. And the number of blowing heads can be adjusted as required.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. These improvements and modifications It should also be regarded as the protection scope of the present utility model.
