Description

Technical Field

[0001] The utility model relates to the field of air blowing mechanisms, in particular to an air blowing mechanism for a strip cutting machine. Background Art

[0002] The slitting machine is mainly used to facilitate the cutting knife to cut the material into strips. The slitting machine is mainly for non-woven interlining, spunbond interlining, double-sided adhesive interlining, cloth strips, nylon interlining, shoemaking, hat making, leather, lining cloth, tape, papermaking, handbags and other industries with different widths, straight and oblique cutting. In the actual slitting work, in order to take the cut cloth out of the cutting disc, an air blowing mechanism will be set to blow the cut cloth out.

[0003] For example, the air blowing mechanism of a slitting machine disclosed in the authorization announcement number CN217434504U, although a fan is set up, the fan provides wind power to the universal bamboo tube through the connecting air pipe and the connecting sleeve. When the slitting machine body is working, the air outlet angle is adjusted to quickly blow the cut cloth away from the cutting disk, thereby realizing rapid material change, and it is simple and fast to use.

[0004] However, the above-mentioned blowing is achieved through an air outlet nozzle, which is a single point-wise blowing nozzle and has no adjustment mechanism to adjust the blowing range. It is not possible to blow the cloth away from the cutting disk well and accurately, but it is easy to blow the cloth to one side. For this reason, we propose an air blowing mechanism for the slitting machine. Utility Model Content

[0005] The purpose of the utility model is to provide an air blowing mechanism for a strip cutting machine.

At the same time, the position of the air outlet baffle can be adjusted by adjusting the component to change the air outlet range of the air outlet nozzle, and a sealing component can be used for sealing to prevent a large amount of gas from escaping.

[0006] To achieve the above object, the utility model provides the following technical solution: an air blowing mechanism for a strip cutting machine, comprising a strip cutting machine body and a universal bamboo tube arranged on the strip cutting machine body, an air blowing assembly is arranged at the end of the universal bamboo tube, and the air blowing assembly comprises:

[0009] An adjusting component, which is arranged on one side of the air outlet nozzle and can drive the air outlet baffle to move;

[0010] A sealing component is fixedly arranged at one end of the air outlet nozzle, and the sealing component can fill the gap between the air outlet baffle and the air outlet nozzle.

[0011] Preferably, the adjustment assembly includes two fixed plates fixedly connected to the outer surface of the air outlet nozzle, a rotating round block rotatably arranged between the two fixed plates, an adjusting threaded rod fixedly connected to one side of the middle part of the rotating round block, and a movable plate threadedly connected to one end of the adjusting threaded rod, and one end of the movable plate is fixedly connected to one side of the air outlet baffle.

[0012] Preferably, the sealing assembly comprises an arc-shaped sleeve fixedly connected to the end face of the air outlet nozzle, a support bar fixedly connected to the inside of the arc-shaped sleeve, and an arc-shaped protrusion fixedly connected to the middle of the arc-shaped sleeve, and the sealing assembly is arranged in a circle around the end of the air outlet nozzle.

[0013] Preferably, both sides of the air outlet baffle are set to be "L" shape, the outer surface of the air outlet nozzle end is fixedly connected to a fixing frame, and the L-shaped side of the air outlet baffle is slidably connected to the side corresponding to the fixing frame.

[0016] Technical effects and advantages of the utility model:

[0017] Air is delivered through a universal bamboo tube and then sprayed out through a flat air outlet nozzle, so that the fabric is better blown up. The flat air outlet nozzle has a larger blowing range and can form a certain fan-shaped blowing range, so as to achieve a better blowing effect. When the blowing range needs to be adjusted later, the air outlet baffle is driven to move by the adjusting component, so that the air outlet baffle is used to block the gas sprayed from the air outlet nozzle, thereby changing the air outlet range of the air outlet nozzle, so as to meet different blowing needs. A sealing component is also provided for sealing, so as to prevent a large amount of gas from escaping from the gap between the air outlet baffle and the air outlet nozzle.
