Description

Technical Field

[0001] This utility model relates to a fiber shearing machine with an automatic monitoring function for cutting status, belonging to the field of automated shearing devices. Background Technology

[0002] Currently, most wool fiber cutting is done using fiber shearing machines. Because wool fibers have a certain degree of elasticity and toughness, they are not as easily cut as other fibers. Therefore, when the fiber shearing machine is running, workers need to check whether the wool fibers have been completely cut. However, manual inspection cannot accurately determine the state of the wool fibers after cutting. Furthermore, wool fibers need to be humidified before shearing, leaving moisture residue on the surface. When the shearing device cuts the wool fibers, they become even more difficult to cut. Moreover, the humidified wool fibers tend to stick together after cutting, making it even harder to determine from the short fibers whether the long fibers have been completely cut.

[0003] To monitor the cutting status of wool fibers, a visual monitoring device can be used. However, the operation of the fiber shearing machine is achieved by the main drive component driving the transmission wheel to achieve high-frequency operation of the shearing device. The high-frequency operation of the shearing device will cause the fiber shearing machine to vibrate during operation. Traditional visual monitoring devices cannot operate accurately and effectively in a vibrating environment because the vibration will cause the high-definition camera to lose focus. In other words, the operation of the fiber shearing machine must be stopped when the traditional visual monitoring device is running. For the above reasons, the existing technology cannot monitor the cutting status of wool fibers in real time. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a fiber shearing machine with automatic monitoring of cutting status that effectively solves the above problems.

[0005] A fiber shearing machine with automatic monitoring of cutting status includes a frame and a device for monitoring the cutting status of wool fibers. The device is fixedly connected to the inside of the frame. A long wool fiber conveyor belt 11 is installed at one end of the frame, and a pressure roller 13 is provided at the end of the long wool fiber conveyor belt. A short wool fiber conveyor belt 4 is installed at the other end of the frame. The long wool fiber conveyor belt 11 and the short wool fiber conveyor belt 4 are staggered at their closest ends. The left end of the short wool fiber conveyor belt 4 is located below the right end of the long wool fiber conveyor belt 11. A shearing device 2 is installed in the part between the long wool fiber conveyor belt 11 and the short wool fiber conveyor belt 4 on the frame. A drive shearing component is also fixedly installed on the frame. The shearing device 2 includes a cutter 21 fixedly connected to the frame. The device for monitoring the cutting status of wool fibers 3 is installed below the shearing device.

[0006] In one embodiment, the drive assembly includes a main drive assembly 6 and a blade adjusting component 7. The main drive assembly 6 includes a main drive motor 61, a secondary transmission wheel 62, and a cutter drive wheel 63. The main drive motor 61 is driven by the secondary transmission wheel 62, and the secondary transmission wheel 62 is driven by the cutter drive wheel 63.

[0007] In one embodiment, the wool fiber cutting status monitoring device 3 is installed at the exit of the blade of the shearing machine cutter 21, and the wool fiber cutting status monitoring device 3 establishes a communication connection with the PLC of the control panel.

[0008] In one embodiment, the wool fiber cutting status monitoring device 3 includes a high-definition camera 31, a base 32, a fixing device 33, a support and anti-shake device 34, and an adjustment device 35. The base 32 includes an upper base 321 and a lower base 322. The upper base 321 is connected to the lower base 322 through the support and anti-shake device 34. The upper base 321 is provided with an upper base threaded hole 332, and the high-definition camera 31 is connected to the upper base 321 through a threaded shaft 331 and the upper base threaded hole 332. The lower base 322 is provided with a lower base threaded hole 333, and is connected to the frame through the lower base threaded hole 333. The support and anti-shake device 34 includes a steel wire rope 341 and a spring 342. The adjustment device 35 includes a first adjustment threaded hole 351 and a second adjustment threaded hole 352 on the upper base 321, and a third adjustment threaded hole 353 and a fourth adjustment threaded hole 354 on the lower base 322.

[0009] The calibration procedure involves taking a photo of the lowest point of the blade of the shearing device 2 before it is loaded with material, using a high-definition camera 31, to obtain a calibration photo. After the wool long fiber shearing operation is completed, the blade of the shearing device 2 reaches its lowest point, and the high-definition camera 31 takes a photo of the cut blade to obtain a post-cut photo. This photo is then compared with the blade in the calibration photo, and the comparison result is used to determine whether all the wool long fibers have been cut.

[0010] If the cut blade is obscured by wool fibers during the comparison, a warning message will be issued indicating that long wool fibers have not been cut, and manual intervention to replace the blade will be required. If the cut blade is not obscured by wool fibers, the PLC will execute subsequent cutting instructions normally.

[0011] Advantages of this utility model:

[0012] (1) In the fiber shearing machine with automatic monitoring of cutting status provided by this utility model, the device for monitoring the cutting status of wool fibers is fixedly connected to the inner side of the frame and installed below the shearing device. The device for monitoring the cutting status of wool fibers is designed with a support and anti-vibration device. When the fiber shearing machine is turned on, the main drive component drives the transmission wheel to move the shearing device up and down. The high frequency operation of the shearing device will cause the fiber shearing machine to vibrate during operation. The device for monitoring the cutting status of wool fibers will also vibrate on the rigid machine. The support and anti-vibration device provided by this utility model will eliminate the vibration transmitted to the high-definition camera through the anti-vibration device, thereby enabling the device for monitoring the cutting status of wool fibers to operate accurately and effectively when the fiber shearing machine is in operation.

[0013] (2) In the fiber shearing machine with automatic monitoring of cutting status provided by the utility model, the device for monitoring the cutting status of wool fibers is connected to the control panel. The device for monitoring the cutting status of wool fibers can determine in real time whether the long wool fibers have been completely cut. In addition, adding the device for monitoring the cutting status of wool fibers to the original fiber shearing machine will not damage the integrity of the original machine, and can better improve the quality of the short wool fibers after cutting.

It can not only effectively avoid the problem of uneven wool fiber length caused by the wool fibers not being cut, but also facilitate the subsequent unmanned, intelligent and automated improvement of the wool fiber shearing machine.

[0020] The following is a detailed description of this utility model.

[0021] Example 1

[0022] Combination Figure 1-3 As shown, this embodiment provides a fiber shearing machine with an automatic monitoring function for cutting status, including a frame and a device for monitoring the cutting status of wool fibers. The device for monitoring the cutting status of wool fibers is fixedly connected to the inside of the frame. A long wool fiber conveyor belt 11 is installed at one end of the frame, and a pressure roller 13 is provided at the very end of the long wool fiber conveyor belt. A short wool fiber conveyor belt 4 is installed at the other end of the frame. The long wool fiber conveyor belt 11 and the short wool fiber conveyor belt 4 are staggered at their closest ends, with the left end of the short wool fiber conveyor belt 4 located below the right end of the long wool fiber conveyor belt 11. A shearing device 2 is installed in the portion between the long wool fiber conveyor belt 11 and the short wool fiber conveyor belt 4 on the frame. A drive assembly for driving the shearing component is also fixedly installed on the frame. The shearing device 2 includes a cutter 21 fixedly connected to the frame, and the device for monitoring the cutting status of wool fibers 3 is installed below the shearing device.

[0023] The drive assembly includes a main drive assembly 6 and a blade adjusting component 7. The main drive assembly 6 includes a main drive motor 61, a secondary transmission wheel 62, and a cutter drive wheel 63. The main drive motor 61 is connected to the secondary transmission wheel 62, and the secondary transmission wheel 62 is connected to the cutter drive wheel 63. A wool fiber cutting status monitoring device 3 is installed at the exit of the shearing machine cutter 21. The wool fiber cutting status monitoring device 3 establishes a communication connection with the PLC of the control panel; for example... Figure 3As shown, the device 3 for monitoring the cutting status of wool fibers includes a high-definition camera 31, a base 32, a fixing device 33, a support and anti-shake device 34, and an adjustment device 35. The base 32 includes an upper base 321 and a lower base 322. The upper base 321 is connected to the lower base 322 through the support and anti-shake device 34. The upper base 321 is provided with an upper base threaded hole 332, and the high-definition camera 31 is connected to the upper base 321 through the threaded shaft 331 and the upper base threaded hole 332. The lower base 322 is provided with a lower base threaded hole 333, and the lower base 322 is connected to the frame through the lower base threaded hole 333. The support and anti-shake device 34 includes a steel wire rope 341 and a spring 342. The two ends of the spring 342 are fixedly connected to the two opposite sides of the upper base 321 and the lower base 322, respectively. The two ends of the steel wire rope 341 are connected to the sides of the upper base 321 and the lower base 322, respectively.

[0024] The adjustment device 35 is used to adjust the shooting angle of the high-definition camera 31 so that it can take pictures of the lowest point after the blade of the shearing device cuts down. It includes a first adjustment threaded hole 351 and a second adjustment threaded hole 352 on the upper base 321, and a third adjustment threaded hole 353 and a fourth adjustment threaded hole 354 on the lower base 322. The wire rope 341 is connected to the side of the upper base 321 through the threaded hole and the corresponding bolt. The length of the wire rope between the upper and lower bases is adjusted by the length of the screw-in threaded hole, thereby adjusting the shooting angle of the high-definition camera on the upper base 321.

[0025] The fiber shearing machine operates by a main drive assembly driving a transmission wheel to achieve high-frequency operation of the shearing device. This high-frequency operation causes vibration within the fiber shearing machine. When this vibration occurs, it is transmitted to the springs, which undergo elastic deformation to absorb some energy, reducing the vibration amplitude and impact. As the vibration decreases, the springs return to their original shape, releasing the stored energy and further reducing the vibration amplitude. Furthermore, the steel wire rope possesses a high modulus of elasticity and tensile strength. During machine operation, the steel wire rope effectively absorbs and attenuates vibrations through its own damping and tension, thereby reducing the vibration transmitted to the equipment and effectively suppressing peak structural vibrations.

[0026] In the fiber shearing machine with automatic monitoring of cutting status provided in this embodiment, the long wool fiber conveyor belt is used to transport the uncut long wool fibers, and the pressure roller device compresses the uncut long wool fibers, which is more conducive to cutting; the short wool fiber conveyor belt is used to transport the cut short wool fibers; the shearing device located between the long wool fiber conveyor belt and the short wool fiber conveyor belt is used to cut the long wool fibers; the wool fiber cutting status monitoring device is used to detect whether the long wool fibers are completely cut and to provide a prompt indicating whether they are completely cut. The drive assembly is used to drive the shearing device to cut the long wool fibers.

[0027] The present invention provides a fiber shearing machine with automatic monitoring of cutting status. Its purpose is to solve the problem of automatically judging whether the long wool fibers have been cut after the long wool fibers have been cut, thereby effectively avoiding the problem of uneven wool fiber length caused by the wool fibers not being cut.

[0028] Combination Figure 5 As shown, the operating steps of the device for monitoring the cutting status of wool fibers of this utility model are as follows:

[0029] 1. A high-definition camera is installed at the exit of the shearing machine blade, and the high-definition camera establishes a communication connection with the PLC of the control panel;

[0030] 2. Calibration procedure: The high-definition camera is used to take a picture of the lowest point after the blade of the shearing device cuts down before the material is loaded, and a calibration photo is obtained;

[0031] 3. After the wool long fiber shearing operation is completed, the blade of the shearing device reaches its lowest point. The high-definition camera takes a picture of the sheared lower blade to obtain a sheared photo, and compares it with the blade position in the calibrated photo. Based on the comparison result, it is determined whether the wool long fiber has been completely cut. This process is repeated once.

[0032] 4. In the comparison results, if the blade is not fully exposed in two consecutive photos after cutting, and the blade is obscured by wool fibers, a warning will be issued indicating that long wool fibers have not been cut. Manual inspection of the fiber cutting machine is required. Figure 4 The diagrams shown illustrate two scenarios: one where the blade is not exposed and the other where it is exposed.

[0033] 5. If the cutter blade is not obscured by wool fibers after shearing, the PLC will execute subsequent shearing commands normally.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
