Specific embodiments

[0018] The following further describes the present invention in detail with reference to embodiments: Embodiment 1 As Figures 1-6As shown in the figure, the present invention provides an intelligent anti-pinch and interlocking emergency stop system for an open mill, including a base 1. An adjustment mechanism 3 is provided on the surface of the base 1, and an emergency stop mechanism 2 is provided on the surface of the adjustment mechanism 3. The emergency stop mechanism 2 includes a partition 212. The partition 212 is fixedly connected to the surface of the adjustment mechanism 3. There are two groups of partitions 212, and the partitions 212 are symmetrically distributed on both sides of the base 1. A first infrared sensor 213, a second infrared sensor 214 and a third infrared sensor 215 are fixedly connected to the surface of the partition 212. The first infrared sensor 213, the second infrared sensor 214 and the third infrared sensor 215 are all electrically connected to a control cabinet 201. The control cabinet 201 is fixedly connected to the surface of the adjustment mechanism 3. The control cabinet 201 is electrically connected to a servo motor 210. The servo motor 210 is fixedly installed on the surface of the partition 212. The output end of the servo motor 210 is fixedly connected to a cam 211. An arc-shaped groove block 206 is movably connected to the surface of the cam 211. A movable seat 203 is fixedly connected to the surface of the arc-shaped groove block 206. A latch 204 is fixedly connected to the surface of the movable seat 203. The latch 204 is fixedly connected to the surface of the adjustment mechanism 3. A slide bar 202 is movably connected to the surface of the movable seat 203. The slide bar 202 is fixedly connected to the surface of the adjustment mechanism 3. A movable rod 208 is fixedly connected to the bottom end of the arc-shaped groove block 206. The movable rod 208 is movably connected to a fixing plate 207. The fixing plate 207 is fixedly connected to the surface of the adjustment mechanism 3. A spring 209 is sleeved on the surface of the movable rod 208 In this embodiment, partitions 212 are provided on both sides of the first roller 304 and the second roller 312, and a first infrared sensor 213, a second infrared sensor 214, and a third infrared sensor 215 are provided on the surfaces of the partitions 212. They are arranged in parallel on both sides of the partition 212. The first infrared sensor 213 is the farthest from the second roller 312, the second infrared sensor 214 is the second farthest, and the third infrared sensor 215 is the closest. They are symmetrically distributed on both sides and cooperate with each other. When the device is operating, the operator extends the hand forward. When the first infrared sensor 213 senses the hand, the controller in the control cabinet 201 drives the motor 302 to decelerate. When the hand is extended further and the second infrared sensor 214 senses the hand, the control cabinet 201 drives the motor 302 to decelerate further. Until the hand reaches the third infrared sensor 215 and is within the dangerous range, the control cabinet 201 drives the cam 211 at the output end of the servo motor 210 to rotate. The cam 211 rotates counterclockwise to push the arc-shaped groove block 206 to displace downward. At this time, the movable rod 208 displaces downward, and the spring 209 is compressed by the arc-shaped groove block 206 and the fixed plate 207. At the same time, the movable seat 203 slides on the surface of the slide rod 202 to drive the latch 204 to latch the ratchet 205, so that the decelerated open mill can quickly stop rotating. When the hand moves away from the third infrared sensor 215, the servo motor 210 drives the cam 211 to rotate, and the spring 209 rebounds to push the unobstructed arc-shaped groove block 206 to reset, so that the latch 204 moves away from the ratchet 205, and the first roller 304 and the second roller 312 rotate again, improving the adaptability and safety of the device.

[0020] In this embodiment, the motor 302 drives the first gear 303 to rotate, so that the first roller 304 rotates. At the same time, through the meshing of the second gear 305, the third gear 307 and the fourth gear 309, the fourth gear 309 drives the second roller 312 on the surface of the rotating rod 316 to rotate synchronously. When it is necessary to adjust the distance between the second roller 312 and the first roller 304, the connecting seat 317 is pulled by the electric telescopic rod 310 on the surface of the support column 311, and the slider 315 slides on the slide rail 314 on the surface of the notch 313, so as to change the position of the second roller 312. At this time, the fourth gear 309, the third gear 307 and the second gear 305 are connected by the connecting rod 306 and the connecting rod 308. When the fourth gear 309 is displaced, the third gear 307 not connected to the side plate 301 adjusts and moves according to the position of the fourth gear 309 and continues to be meshed, so that the transmission can still be maintained during the adjustment process. At the same time, the device can also separate the first roller 304 and the second roller 312 in time when the operator's hand is stuck, so that it can be used as a safety redundancy device to prevent pinching, improving the adaptability and safety of the device.

[0021] Next, the working principle of the intelligent anti-pinching linkage emergency stop system of the open mill will be specifically described.

[0022] As shown Figures 1-6 in the figure, the first gear 303 is driven to rotate by the motor 302, so that the first roller 304 rotates. At the same time, through the meshing of the second gear 305, the third gear 307 and the fourth gear 309, the fourth gear 309 drives the second roller 312 on the surface of the rotating rod 316 to rotate synchronously. When it is necessary to adjust the distance between the second roller 312 and the first roller 304, the electric telescopic rod 310 on the surface of the support column 311 is used to pull the connecting seat 317, and the slider 315 slides on the slide rail 314 on the surface of the notch 313, so as to change the position of the second roller 312. At this time, the fourth gear 309, the third gear 307 and the second gear 305 are connected by the connecting rod 306 and the connecting rod 308. When the fourth gear 309 is displaced, the third gear 307 not connected to the side plate 301 is adjusted and moved according to the position of the fourth gear 309 and continues to mesh, so that the transmission can still be maintained during the adjustment. At the same time, the device can also separate the first roller 304 and the second roller 312 in time when the operator's hand is stuck, so that it can be used as a safety redundancy device to prevent pinching. Partition plates 212 are arranged on both sides of the first roller 304 and the second roller 312, and first infrared sensors 213, second infrared sensors 214 and third infrared sensors 215 are arranged on the surface of the partition plates 212. They are arranged in parallel on both sides of the partition plates 212. The first infrared sensor 213 is the farthest from the second roller 312, the second infrared sensor 214 is the second, and the third infrared sensor 215 is the closest. They are symmetrically distributed on both sides and cooperate with each other. When the device operates, the operator's hand extends forward. When the first infrared sensor 213 senses the hand, the controller in the control cabinet 201 drives the motor 302 to decelerate. When the hand extends forward further and the second infrared sensor 214 senses the hand, the control cabinet 201 drives the motor 302 to decelerate further. Until the hand reaches the third infrared sensor 215, it is in the dangerous range. The control cabinet 201 drives the cam 211 at the output end of the servo motor 210 to rotate. The cam 211 rotates counterclockwise to push the arc-shaped groove block 206 to displace downward. At this time, the movable rod 208 displaces downward, and the spring 209 is compressed by the extrusion of the arc-shaped groove block 206 and the fixed plate 207. At the same time, the movable seat 203 slides on the surface of the slide rod 202 to drive the clamping block 204 to clamp the ratchet wheel 205, so that the decelerated open mill can stop rotating quickly. When the hand moves away from the third infrared sensor 215, the servo motor 210 drives the cam 211 to rotate, and the spring 209 rebounds to push the unblocked arc-shaped groove block 206 to reset, so that the clamping block 204 moves away from the ratchet wheel 205, and the first roller 304 and the second roller 312 rotate again, improving the adaptability and safety of the device.

[0023] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art.
