[0028] The utility model is further described in detail below based on the drawings and embodiments.
[0029] Example
[0030] Please refer to Figures 1 to 6 As shown:
[0031] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an ultrasonic grooveless cutting device for tire nylon cord, including a processing table 1, a control component 102 is arranged on the top of the processing table 1, a mounting frame 103 is slidably mounted on the control component 102, and a tool 104 is arranged between the opposite surfaces of the mounting frame 103, which is used to adjust the movement of the tool 104 to facilitate the cutting of the nylon cord; a conveying component 101 is arranged on the top of the processing table 1, and the conveying component 101 is located below the mounting frame 103, wherein the conveying component 101 is used to convey the nylon cord to advance, so that the device can quickly cut the nylon cord, thereby improving the processing efficiency of the cutting work; sliding frames 2 are arranged on both sides of the mounting frame 103, which are used to improve the flatness of the nylon cord To provide power, a slider 201 is slidably installed inside the sliding frame 2, a guide rod 204 is fixedly installed on the side of the slider 201 away from the sliding frame 2, and a trigger rod 205 is fixedly installed at the bottom of the guide rod 204; connecting plates 3 are rotatably installed on both sides of the mounting frame 103, and limiting grooves 301 are provided on the opposite surfaces of the connecting plates 3, and the limiting grooves 301 are adapted to the guide rod 204, and rollers 302 are rotatably installed between the opposite surfaces of the bottom of the connecting plates 3, wherein the trigger rod 205 can provide power in the process of the mounting frame 103 driving the tool 104 to descend and fit the nylon cord, prompting the rollers 302 to fit the nylon cord and squeeze the nylon cord to roll to both sides of the tool 104 during the descent of the tool 104, so that the uneven nylon cord is flattened by the rollers 302 before contacting the tool 104.
[0032] Specifically, a limit rod 202 is fixedly provided inside the sliding frame 2, and the slider 201 is slidably installed on the outer surface of the limit rod 202. When the guide rod 204 is pushed by the nylon curtain, it slides upward along the limit rod 202. A return spring 203 is fixedly installed between the opposite surfaces of the slider 201 and the sliding frame 2. The return spring 203 is sleeved on the outer surface of the limit rod 202. The return spring 203 is stretched and retracted under force, and the guide rod 204 can be reset for subsequent use.
[0033] Specifically, a ball 206 is movably installed at the bottom of the guide rod 204. Since the outer surface of the ball 206 is designed to be smooth, the ball 206 can facilitate the guide rod 204 to move with the tool 104, so that the bottom end of the guide rod 204 will not damage the surface of the nylon cord as much as possible to avoid affecting its performance.
[0034] It should be noted that there are four connecting plates 3, which are symmetrically distributed around the sliding frame 2, two rollers 302, which are symmetrically distributed around the guide rod 204, and the outer surfaces of the rollers 302 are designed to be smooth to prevent the surfaces of the rollers 302 from damaging the nylon cord fabric.
[0035] Further examples:
[0036] Please refer to Figures 1 to 6 As shown: the bottom of the four connecting plates 3 are fixedly installed with a buffer cylinder 4, and the buffer cylinder 4 is of a sealed design. The buffer cylinder 4 is slidably provided with a sealing plug 401, and a connecting column 403 is installed at the bottom of the sealing plug 401. When the sealing plug 401 is lifted upward by the connecting column 403, the compressed air inside the buffer cylinder 4 can provide a certain buffering force for the connecting plate 3. The bottom of the connecting column 403 is movably provided with a ball 2 404, and the outer surface of the ball 2 404 is of a smooth design, which is used to reduce the friction between the connecting column 403 and the nylon cord, so that the connecting plate 3 drives the roller 302 to move with the tool 104. The horizontal height of the ball 2 404 is lower than the horizontal height of the roller 302, which is used to ensure that the roller 302 can move with the tool 104, and avoid the situation where the vibration force generated by the tool 104 is only transmitted through the roller 302, resulting in damage to the device. A telescopic spring 402 is fixedly installed between the sealing plug 401 and the opposite surface of the inner wall of the buffer tube 4. The elastic performance of the telescopic spring 402 can further reduce the impact force between the connecting column 403 and the nylon cord.
[0037] It is worth mentioning that, during the process of the tool 104 cutting the nylon cord, the contact area between the device and the nylon cord is increased through the four connecting columns 403. The connecting columns 403 are subjected to the vibration force and slide toward the inside of the buffer tube 4 and squeeze the sealing plug 401 to slide. At this time, the internal space of the buffer tube 4 is reduced, and the air pressure increases accordingly, so that the vibration force on the connecting columns 403 is reduced. At the same time, the telescopic spring 402 arranged inside the buffer tube 4 can further improve the buffering force between the connecting column 403 and the nylon cord by relying on the elastic properties of the telescopic spring 402, thereby effectively reducing the vibration force of the tool 104 during cutting.
[0038] Everything in the above example works like this:
[0039] When in use, the worker first places the nylon cord to be cut on the conveying component 101, and the conveying component 101 conveys the nylon cord to be cut to below the cutter 104, so as to cut the nylon cord to the required length, thereby facilitating the subsequent tire manufacturing work;
[0040] When the control component 102 drives the cutter 104 on the mounting frame 103 to descend, the trigger rod 205 also descends and first contacts the nylon cord. Then the trigger rod 205 is stressed to push the slider 201 to slide along the inside of the sliding frame 2 and continuously squeeze the return spring 203 to contract. At this time, the guide rod 204 at the top of the trigger rod 205 slides along the limit grooves 301 on the connecting plates 3 on both sides, thereby increasing the angle between the two connecting plates 3. The roller 302 at the bottom of the connecting plate 3 rolls along the surface of the nylon cord. As the mounting frame 103 continues to descend, the roller 302 is always in close contact with the surface of the nylon cord, thereby flattening the wrinkled nylon cord. This can effectively avoid the inaccurate ultrasonic cutting caused by the uneven nylon cord, and make the shape and size of the ultrasonic cutting more accurate, thereby improving the manufacturing quality of the tire. At the same time, it can also make the quality of the cut products consistent and avoid differences between products of different batches.
[0041] When the roller 302 is leveled along the surface of the nylon cord, the connecting column 403 arranged in the buffer cylinder 4 also contacts the surface of the nylon cord. When the tool 104 performs ultrasonic cutting, the connecting column 403 is subjected to the vibration force and slides toward the inside of the buffer cylinder 4 and squeezes the sealing plug 401 to slide. At this time, the internal space of the buffer cylinder 4 is reduced, and the air pressure increases accordingly, so that the vibration force on the connecting column 403 is reduced. At the same time, the telescopic spring 402 arranged inside the buffer cylinder 4 can further improve the buffering force between the connecting column 403 and the nylon cord by relying on the elastic properties of the telescopic spring 402, thereby effectively reducing the vibration force of the tool 104 during cutting.
