A movable plate is fixedly installed at one end of the movable rod. Guide rods are symmetrically slidably connected inside the fixed plates on both sides of the movable rod, and both guide rods are fixedly connected to the movable plate.

[0012] The movable rod is fitted with a telescopic spring on its outer side, with one end of the telescopic spring fixedly connected to the movable plate and the other end of the telescopic spring fixedly connected to the fixed plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This emergency anti-breakage cotton net device for a combing machine has a braking component set inside the housing, which allows the rotating rod to be simultaneously braked by friction after the combing machine stops. This enables timely braking of the guide rollers, increases the friction force during the braking process, avoids the inability to stop the guide rollers in time after prolonged use, and extends the service life. The specific details are as follows:

[0020] 1. A braking assembly is installed inside the casing. During the operation of the combing machine, the guide roller and the rotating rod rotate. At this time, the electromagnet is energized, causing the electromagnet and the control board to repel each other, and the two movable plates to move away from each other. The telescopic spring is in a compressed state. After the guide roller stops rotating, the electromagnet is de-energized, so that the electromagnet no longer repels the control board. At this time, under the action of the telescopic spring, the two movable plates move closer to each other, which in turn causes the two moving plates to move, so that the two braking blocks come into contact with the rotating rod. The rotating rod is stopped by friction, so that the guide roller stops moving after the power is de-energized. This prevents the guide roller from continuing to rotate under the action of inertia and breaking the cotton web. The braking assembly allows the two sides of the rotating rod to be braked simultaneously after the combing machine stops, which can stop the guide roller in time. It can improve the friction force during the braking process and avoid the guide roller not being able to stop in time after long-term use, thus improving the service life.

[0021] 2. When it is necessary to adjust the friction force of the two braking blocks, the knob can be turned to drive the rotating rod to rotate. The meshing of the first and second bevel gears drives the rotating shaft to rotate. Then, the connecting bar and the connecting groove drive the connecting shaft to rotate. When the moving plate moves, the connecting shaft moves without affecting the transmission of the rotating shaft to the connecting shaft. Then, the two threaded rods can be rotated simultaneously, which can control the two moving plates to move closer or further away at the same time. During the movement of the moving plates, they slide on the sliding rod for limit, thereby adjusting the distance between the movable plate and the moving plate. It can also make the adjustment displacement of the two moving plates consistent, avoiding affecting the subsequent braking of the rotating rod. This makes it convenient for the staff to adjust the distance between the two braking blocks, adjust the friction force of the braking blocks, and improve practicality. Attached Figure Description

All 204 are fixedly connected to the movable plate 203. A telescopic spring 205 is sleeved on the outer side of the movable rod 202. One end of the telescopic spring 205 is fixedly connected to the movable plate 203, and the other end of the telescopic spring 205 is fixedly connected to the fixed plate 201. Sliding rods 206 are symmetrically installed on the upper side of the two movable plates 203 that are close to each other. After the combing machine stops, the two sides of the rotating rod 101 can be simultaneously braked by friction through the braking assembly 2. The guide roller 102 can be stopped in time, which can improve the friction force during the braking process and avoid the guide roller 102 not being able to be stopped in time after long-term use, thus improving the service life.

[0030] Each of the two sliding rods 206 on each side is slidably connected to a movable plate 207. A mounting bracket 208 is symmetrically installed above one side of each movable plate 207. A brake block 209 is fixedly installed on the side of each mounting bracket 208 away from the movable plate 207, which can brake the rotating rod 101. A connecting rod 212 is hinged to the top of each of the two movable plates 203. A control plate 211 is hinged to the end of each connecting rod 212 away from the movable plate 203. Limit rods 210 are symmetrically installed on the top of the control plate 211. The limit rods 210... Electromagnets 213 are symmetrically mounted on the top of the housing 1 above the control plate 211, allowing the control plate 211 to move and drive two movable plates 203 to move simultaneously. The bottom of the housing 1 has symmetrically opened movable slots 214, with both movable plates 203 and moving plates 207 slidably connected to them, guiding their movement. Threaded rods 215 are rotatably connected to the lower side of the two movable plates 203 that are close to each other. The moving plates 207 and threaded rods 215 are also rotatably connected. The two threaded rods 215 are connected by threaded joints, with connecting shafts 216 fixedly mounted at their adjacent ends. Each connecting shaft 216 has a sliding groove 217 inside, and a rotating shaft 218 is slidably connected inside the sliding grooves 217, allowing adjustment of the positions of the two movable plates 207. Connecting strips 219 are symmetrically installed inside the sliding grooves 217, and connecting grooves 220 are symmetrically formed on both sides of the rotating shaft 218. The connecting strips 219 are slidably connected to the connecting grooves 220, allowing the connecting shafts 216 to... The rotating shaft 218 can drive the connecting shaft 216 to rotate. A fixed frame 221 is fixedly installed inside the housing 1. A first bevel gear 222 is fixedly installed on the outer side of the rotating shaft 218. A rotating rod 223 is rotatably connected to the lower part of the fixed frame 221. A second bevel gear 224 is fixedly installed on the top of the rotating rod 223. The second bevel gear 224 meshes with the first bevel gear 222. A knob 225 is fixedly installed on the bottom of the rotating rod 223, so that the two threaded rods 215 can be controlled to rotate simultaneously.

[0031] Working principle: Before using this emergency anti-breakage cotton net device for combing machines, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 5As shown, a braking assembly 2 is installed inside the housing 1. During the operation of the combing machine, the guide roller 102 and the rotating rod 101 rotate. At this time, the electromagnet 213 is energized, causing the electromagnet 213 to repel the control plate 211, thus moving the two movable plates 203 away from each other. The telescopic spring 205 is in a compressed state. After the guide roller 102 stops rotating, the electromagnet 213 is de-energized, so that the electromagnet 213 no longer repels the control plate 211. At this time, under the action of the telescopic spring 205, the two movable plates 203 are brought closer together, thereby causing the combing machine to stop rotating. The two movable plates 207 move, causing the two braking blocks 209 to abut against the rotating rod 101. The rotating rod 101 is stopped by friction, so that the guide roller 102 stops moving after the power is cut off. This prevents the guide roller 102 from continuing to rotate under inertia and breaking the cotton web. The braking component 2 allows the rotating rod 101 to be braked simultaneously on both sides after the combing machine stops. This can stop the guide roller 102 in time, increase the friction force during the braking process, and prevent the guide roller 102 from failing to stop in time after long-term use, thus extending the service life.

[0032] When it is necessary to adjust the friction force of the two braking blocks 209, the knob 225 can be turned to drive the rotating rod 223 to rotate. The meshing of the first bevel gear 222 and the second bevel gear 224 drives the rotating shaft 218 to rotate. Then, the connecting rod 219 and the connecting groove 220 cooperate to drive the connecting shaft 216 to rotate. When the moving plate 207 moves, the connecting shaft 216 moves without affecting the transmission of the rotating shaft 218 to the connecting shaft 216. Then, the two threaded rods 215 can be rotated at the same time, which can control the two moving plates 207 to move closer or further away at the same time. During the movement of the moving plate 207, it slides on the sliding rod 206 for limit, thereby adjusting the distance between the movable plate 203 and the moving plate 207. It can also make the adjustment displacement of the two moving plates 207 consistent, avoiding affecting the subsequent braking of the rotating rod 101. This makes it convenient for the staff to adjust the distance between the two braking blocks 209 and adjust the friction force of the braking blocks 209, thus improving practicality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
