Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shearing machines, in particular to an automatic hair blowing device for circular knives. Background Technique
[0002] A shearing machine is a textile post-treatment device and one of the main devices for post-treatment of plush products. Shearing machines are also designed in various different structural combinations, and their forms mainly include single-knife shearing machines, ironing and shearing machines, brushing, ironing and shearing combined machines, raising and shearing combined machines, etc. At present, in the existing brushing, ironing and shearing combined machines, the fabric is brushed before shearing, which can remove floating fibers and debris on the surface, pull out the hidden fluff fibers, and straighten the direction of the fluff, which is beneficial to shearing the fluff flat.
[0003] During the operation of the shearing machine, it is necessary to blow the debris at the gap of the circular knife to ensure the normal operation of the circular knife. The existing blowing method is that the operator holds a hose to blow, with low operation efficiency and certain danger. Therefore, we propose an automatic hair blowing device for circular knives. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an automatic hair blowing device for circular knives.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] An automatic hair blowing device for circular knives, including a frame and a servo push rod arranged on the frame and parallel to the circular knife. An air storage box is installed on the push rod slider of the servo push rod. One end of an air pipe is connected to the air storage box, and the other end of the air pipe is connected to a spray head. The air outlet of the spray head is aligned with the circular knife. Travel switches are installed on the frame at positions corresponding to both ends of the servo push rod, and the travel switches are electrically connected to the servo push rod.
[0007] Preferably, the spray head is flat, and the length direction of the spray head is consistent with the length direction of the circular knife.
[0008] Preferably, an air inlet is further provided on the air storage box.
[0009] Preferably, the stroke length of the servo push rod is the same as the length of the cutting edge of the circular knife.
[0010] The beneficial effect of the utility model is that in this device, the servo push rod drives the spray head to reciprocally blow the circular knife, enabling the circular knife to operate normally. And the whole operation process requires no manual intervention, with high operation efficiency and good safety. Description of the Drawings

[0014] In the figure: 1 frame, 2 circular knife, 3 servo push rod, 4 push rod slider, 5 air pipe, 6 nozzle, 7 air storage box, 8 air inlet, 9 travel switch. Specific embodiments
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0016] Refer to Figures 1 - 3 , an automatic circular knife hair blowing device, including a frame 1 and a servo push rod 3 arranged on the frame 1 and parallel to the circular knife 2. An air storage box 7 is installed on the push rod slider 4 of the servo push rod 3. One end of an air pipe 5 is connected to the air storage box 7. The air pipe 5 is a rigid steel pipe (metal pipe). The other end of the air pipe 5 is connected to a nozzle 6. The air outlet of the nozzle 6 is aligned with the circular knife 2. Travel switches 9 are installed at positions corresponding to both ends of the servo push rod 3 on the frame 1. The travel switches 9 are electrically connected to the servo push rod 3. During the movement of the push rod slider 4, when approaching the travel switch 9, it will stop and then move in the opposite direction.
[0017] The nozzle 6 is flat, and the length direction of the nozzle 6 is consistent with the length direction of the circular knife 2.
[0018] An air inlet 8 is also provided on the air storage box 7. The air inlet 8 can be connected to a hose, and the hose is connected to a compressed air source. The air storage box 7 is supplied with air through the hose, and the air storage box 7 supplies air to the air pipe 5.
[0019] The stroke length of the servo push rod 3 is the same as the blade length of the circular knife 2. During actual operation, the stroke length of the servo push rod 3 can be slightly greater than the blade length of the circular knife 2 to ensure that the end of the circular knife 2 can also be cleaned thoroughly.
[0020] In this device, the servo push rod 3 drives the push rod slider 4 to move. The air storage box 7 follows the push rod slider 4 to move, and the nozzle 6 reciprocally blows the circular knife 2, enabling the circular knife 2 to operate normally. Moreover, the entire operation process requires no manual intervention, has high operation efficiency, and good safety.
[0021] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
