All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1 As shown, this embodiment proposes a convenient positioning car sunroof rubber strip cutting device, including a support platform 1. The top of the support platform 1 is provided with a cutting mechanism 2 for cutting the sunroof rubber strip. The two sides of the cutting mechanism 2 are respectively provided with a first positioning component 3 and a second positioning component 4 for fixing the rubber strip during cutting.

[0028] like Figure 3 As shown, the cutting mechanism 2 includes a frame 201 fixedly connected to the top of the support platform 1. A cylinder 202 is fixedly connected to the top of the frame 201. A mounting shell 203 is fixedly connected to the output end of the cylinder 202. A cutting blade 204 is bolted inside the mounting shell 203. The cylinder 202 is used to push the cutting blade 204 down to cut the rubber strip. A discharge hole 205 is provided on the top of the support platform 1. The discharge hole 205 is used to discharge the debris generated when cutting the rubber strip. The discharge hole 205 is located directly below the cutting blade 204. In use, the rubber strip is placed directly below the cutting blade 204, and then the cylinder 202 is started. The cylinder 202 drives the cutting blade 204 down to perform the cutting operation. After the cutting is completed, the power of the cylinder 202 is turned off, and the debris generated during cutting is swept off from the discharge hole 205 to improve the cleanliness of the top of the support platform 1.

[0029] like Figure 4As shown, the first positioning component 3 includes a first fixing frame 301 and a second fixing frame 302 respectively fixedly connected to the top of the support platform 1. A first roller 303 is disposed between the first fixing frame 301 and the second fixing frame 302. A second roller 304 is rotatably connected to the top of the support platform 1. A lead screw 305 is rotatably connected inside the first fixing frame 301. A slider 306 is threadedly connected to the outside of the lead screw 305. The slider 306 is rotatably connected to one end of the first roller 303. Rotating the lead screw 305 can adjust the distance between the first roller 303 and the second roller 304 to avoid excessive squeezing. The adhesive strip is attached to the outer wall of the support platform 1 by a motor 307. The output end of the motor 307 is fixedly connected to the side wall of the second roller 304. When in use, the motor 307 is started, and the motor 307 drives the second roller 304 to rotate. At this time, the adhesive strip is inserted between the first roller 303 and the second roller 304. The adhesive strip will fill the gap between the first roller 303 and the second roller 304. When the adhesive strip moves, the first roller 303 will rotate, thereby sending the adhesive strip under the cutting blade 204. At the same time, the first roller 303 and the second roller 304 can also fix one end of the adhesive strip.

[0030] like Figure 5 As shown, the second positioning component 4 includes a connecting pipe 401 fixedly connected to the side wall of the mounting shell 203 away from the first roller 303. A slide rod 402 is slidably connected inside the connecting pipe 401. A pressure plate 403 is fixedly connected to the bottom of the slide rod 402. A fixing plate 404 is fixedly connected to the outer wall of the connecting pipe 401. A spring 405 is fixedly connected to the bottom of the fixing plate 404. The bottom of the spring 405 is fixedly connected to the top of the pressure plate 403. When the cylinder 202 drives the mounting shell 203 and the cutting blade 204 to descend, the connecting pipe 401 will also descend. Then the pressure plate 403 will first contact the rubber strip. As the mounting shell 203 descends, the pressure plate 403 will press down on the rubber strip. Then the spring 405 will contract. At this time, both ends of the rubber strip are fixed. When the cutting blade 204 cuts it, it can prevent it from moving and improve the accuracy of cutting.

[0031] like Figure 1 As shown, a first guide rail 5 and a second guide rail 6 are respectively provided on both sides of the feeding hole 205 to limit the rubber strip. The end of the first guide rail 5 away from the second guide rail 6 is flared. In use, the first guide rail 5 and the second guide rail 6 can prevent the rubber strip from moving to the ends of the cutting blade 204, thereby improving the cutting efficiency.

[0032] like Figure 4As shown, two blocking posts 7 are fixedly connected to the side wall of the support platform 1 near the first fixed frame 301. The two blocking posts 7 are arranged opposite each other, and the side walls of the two blocking posts 7 are in contact with the outer walls of the first roller 303 and the second roller 304. When in use, the two blocking posts 7 can block one end of the first roller 303 and the second roller 304 to prevent the rubber strip from being sent into the outside of the first guide rail 5.

[0033] like Figure 4 As shown, rectangular plates 8 are fixedly connected to the opposite side walls of the mounting shell 203, and a guide rod 9 is fixedly connected to the top of the support platform 1. One end of the guide rod 9 passes through the rectangular plate 8 and is slidably connected to the rectangular plate 8. When the mounting shell 203 descends, it will drive the rectangular plate 8 to descend along the guide rod 9, thereby improving the stability of the cutting blade 204 when it descends.

[0034] like Figure 1 As shown, hydraulic rods 10 are fixedly connected to both ends of the bottom of the fixed plate 404. The bottom of the two hydraulic rods 10 is fixedly connected to the top of the pressure plate 403. When in use, the two hydraulic rods 10 can prevent the spring 405 from shaking when resetting, thus playing a damping role.

[0035] Specifically, when using this convenient positioning car sunroof rubber strip cutting device: connect cylinder 202 and motor 307 to an external power source, start motor 307, and motor 307 drives the second roller 304 to rotate. At this time, insert the rubber strip between the first roller 303 and the second roller 304. The rubber strip will fill the gap between the first roller 303 and the second roller 304. When the rubber strip moves, the first roller 303 will rotate, thereby feeding the rubber strip under the cutting blade 204 (e.g., Figure 4 As shown), the first roller 303 and the second roller 304 can also fix one end of the rubber strip. Then, the cylinder 202 is activated, and the cylinder 202 drives the mounting shell 203 and the cutting blade 204 to descend (as shown). Figure 3 As shown), the connecting pipe 401 will also descend, and then the pressure plate 403 will first contact the rubber strip. As the mounting shell 203 descends, the pressure plate 403 will press down on the rubber strip. Then the spring 405 will contract, and at this time, both ends of the rubber strip are fixed to prevent it from moving (as shown). Figure 5 As shown), to improve the accuracy of cutting, cylinder 202 drives the cutting blade 204 to descend, thereby performing the cutting operation. After cutting is completed, the power to cylinder 202 is turned off, and the debris generated during cutting is swept off from the discharge hole 205, improving the cleanliness of the top of the support table 1 (as shown). Figure 3 (As shown).

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
