[0001] The utility model relates to the technical field of helmet production, in particular to an automatic helmet trimming device. Background Technique

[0002] A helmet is a device for protecting the head. It is a hat worn by soldiers during training and combat. It is an indispensable tool in people's transportation. It is divided into military helmets, police helmets, and civilian helmets, etc. It is mostly semi-circular and mainly consists of three parts: a shell, a lining, and a suspension device. The shell is made of special steel, fiberglass, reinforced plastic, leather, nylon and other materials to resist the damage of bullets, shrapnel and other striking objects to the head. When producing helmets, an automatic trimming device is needed to cut off the redundant parts at the corners of the helmet. However, most of the existing trimming devices adsorb the helmet to fix it. However, during trimming, the helmet may shift, so the trimming quality of the helmet may be reduced. Content of the Utility Model

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-7, the present utility model provides a technical solution: a helmet automatic trimming device, including an automatic trimming mechanism 1. A clamping component 2 is arranged outside the automatic trimming mechanism 1, and an adjusting component 3 is arranged outside the clamping component 2. An anti-detachment component 4 is connected outside the adjusting component 3. The anti-detachment component 4 includes a first fixing block 401 and a second sleeve 403. A groove 402 is opened in the lower part of the first fixing block 401. A fixing rod 404 is sleeved inside the second sleeve 403, and a return spring 405 is snap-connected under the fixing rod 404. One end of the return spring 405 is snap-connected inside the second sleeve 403. A second chute 406 is opened outside the second sleeve 403, and a second slider 407 is slidably connected inside the second chute 406. A plurality of second chutes 406 are sequentially arranged along the outside of the second sleeve 403. A push rod 408 is rotatably connected outside the second slider 407, and a second fixing block 409 is rotatably connected to one side of the push rod 408. An anti-slip rubber 410 is adhered to one side of the second fixing block 409. A first telescopic rod 411 is fixedly connected to the other side of the second fixing block 409, and one end of the first telescopic rod 411 is fixedly connected to the outside of the second sleeve 403. A second fixing plate 5 is fixedly connected under the second sleeve 403. By providing the first fixing block 401 and the groove 402, it is convenient to fix the helmet. By providing the return spring 405, when the return spring 405 keeps its original length, the fixing rod 404 is pushed out. When the return spring 405 is compressed, the fixing rod 404 shrinks into the second sleeve 403. By providing the first telescopic rod 411, the moving direction of the second fixing block 409 is ensured. By providing the second chute 406 and the second slider 407, the second slider 407 is ensured to slide along the second chute 406. By providing the push rod 408, when the second slider 407 moves, the second slider 407 pushes the second fixing block 409 to move. By providing the anti-slip rubber 410, the friction between the second fixing block 409 and the inner wall of the helmet is increased.

[0024] The automatic trimming mechanism 1 includes a trimming machine main body 101, and a vertical plate 102 is fixedly connected to the trimming machine main body 101. A slide rail 103 is opened on one side of the vertical plate 102, and a stepping motor 104 is slidably connected inside the slide rail 103.

[0025] One side of the stepping motor 104 is fixedly connected to a connecting plate 105, and an electric telescopic rod 106 is fixedly connected to one side of the connecting plate 105. One end of the electric telescopic rod 106 is fixedly connected to a cutting machine 107. A collection box 108 is slidably connected inside the trimming machine main body 101.

[0026] The clamping component 2 includes a first chute 203, and the first chute 203 is opened on the back of the vertical plate 102. A first slider 202 is slidably connected inside the first chute 203, and a bidirectional lead screw 201 is rotatably connected inside the first slider 202.

[0027] One end of the bidirectional lead screw 201 is fixedly connected to a support plate 204, and the support plate 204 is disposed opposite to the second fixing plate 5.

[0028] The adjusting assembly 3 includes a first sleeve 301, and a first support rod 302 is slidably connected inside the first sleeve 301. A clamping hole 303 is formed outside the first sleeve 301, and two first sleeves 301 are disposed opposite to each other. By providing the first sleeve 301 and the first support rod 302, when the first support rod 302 is pulled out of the first sleeve 301, the height between the first sleeve 301 and the first support rod 302 can be easily adjusted.

[0029] A plurality of clamping holes 303 are sequentially arranged along the outside of the first sleeve 301. A clamping pin 304 is snap-fitted outside the first sleeve 301, and the clamping pin 304 is correspondingly arranged with the clamping hole 303. The clamping pin 304 is snap-fitted with the first support rod 302, and a first fixing plate 305 is fixedly connected to the outside of the first support rod 302. By providing the clamping hole 303 and the clamping pin 304, when the clamping pin 304 is snap-fitted with the first sleeve 301, the first sleeve 301 and the first support rod 302 can be easily fixed.

[0030] Working principle: When trimming the edge of the helmet, first, the clamping pin 304 is disengaged from the first sleeve 301. Secondly, by pulling the first fixing plate 305, the first fixing plate 305 pulls the first support rod 302 out of the first sleeve 301, thereby adjusting the length of the first sleeve 301. Then, the first sleeve 301 and the first support rod 302 are fixed by the clamping pin 304 and the corresponding clamping pin 304, so as to easily adjust the height of the first fixing block 401 and facilitate clamping helmets of different sizes. Then, the helmet is placed on the fixing rod 404 so that the fixing rod 404 fits inside the helmet. Secondly, by rotating the bidirectional lead screw 201, the first slider 202 moves along the direction of the first chute 203, so that the first fixing plate 305 and the second fixing plate 5 approach each other, and the first fixing block 401 approaches the helmet. When the groove 402 fits with the helmet, the helmet pushes the fixing rod 404 to move along the second sleeve 403 and compresses the return spring 405, so that the fixing rod 404 pushes the second slider 407 to move along the second chute 406, thereby pushing one end of the push rod 408 to move along the second chute 406, so that one end of the push rod 408 pushes the second fixing block 409 to approach the inside of the helmet and drives the first telescopic rod 411 to extend. The anti-slip rubber 410 increases the friction between the second fixing block 409 and the inner wall of the helmet and fixes the inner wall of the helmet in multiple directions, thereby preventing the helmet from shifting during cutting and ensuring the trimming quality. Finally, by starting the stepping motor 104, the connecting plate 105 moves along the slide rail 103. Secondly, the electric telescopic rod 106 is operated by an external power supply to push the trimming machine 107 towards the helmet, so that the trimming machine 107 trims the edge of the helmet, thus completing the trimming of the helmet edge.

[0031] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present utility model, rather than limiting the protection scope of the present utility model. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present utility model shall not depart from the essence and scope of the technical solution of the present utility model.
