Description

Technical Field

[0001] This utility model belongs to the field of spinning machine spindle rotation detection technology, and in particular relates to a spinning machine spindle rotation monitoring device. Background Technology

[0002] In the production process of a ring spinning frame, the rotation of the roving roller is passive. The stable rotation of the roving roller directly reflects and relates to the continuity of roving conveying and production efficiency. At the same time, roving breakage and depletion will cause the roving roller to stop rotating. In the current technology, the ring spinning frame spindle does not have a dedicated detection device for the rotation status of the roving roller, and it is impossible to obtain the rotation status of the roving roller in real time. As a result, it is difficult to detect when the roving breaks or is depleted in time, and it can only rely on manual periodic inspections for judgment. This method is not only inefficient and has detection lag, but it is also prone to affecting the continuity of production due to human misjudgment, and may even cause potential product quality problems. Summary of the Invention

[0003] The purpose of this utility model embodiment is to provide a spinning frame bobbin rotation monitoring device, which aims to solve the problem that existing spinning frame bobs lack dedicated detection methods and cannot automatically and in real time monitor the rotation status of the roving roller.

[0004] The present invention is implemented as follows: A spinning frame spindle rotation monitoring device includes a hook, a rotating shaft rotatably mounted at the bottom of the hook, at least one sensing block fixed to the side wall of the rotating shaft, and a number of sensors corresponding to the sensing blocks at the bottom of the hook. Each sensor has a sensing head; when a sensing block passes in front of the sensing head, the sensor generates a signal indicating that the rotating shaft has rotated one revolution. A connecting part is located at the bottom of the rotating shaft, and the connecting part is connected to the roving roller via a plug-in or threaded connection. The rotation of the roving roller is detected by monitoring the rotation of the rotating shaft.

[0005] Furthermore, the bottom of the hook is provided with a U-shaped notch, and symmetrical fixing protrusions are provided inside the notch. A base is provided between the two fixing protrusions, and fixing holes are provided symmetrically on both sides of the base. The fixing protrusions are inserted into the fixing holes.

[0006] Furthermore, the base has a central hole that penetrates the base, a rotating shaft is inserted into the central hole, the top of the base has a groove, an end face bearing is installed in the groove, and the top of the end face bearing is a T-shaped head of the rotating shaft, which presses the end face bearing into the groove.

[0007] Furthermore, the T-shaped head is equipped with a fastening head, the sensing block is fixed on the side of the fastening head or the T-shaped head, and the sensor is fixed at the position where the hook and the sensing block 5 are directly opposite each other, with the sensing head and the sensing block directly opposite each other.

[0008] Furthermore, a dust cover is provided on the side of the rotating shaft of the sensing block and at the bottom of the base. The sensor is fixed in a position where the dust cover is directly opposite the sensing block, and the sensing head is directly opposite the sensing block.

[0009] Furthermore, the top of the hook is either closed or has an installation notch.

[0010] The positive effects of this invention are as follows: By cooperating with the sensor on the rotating shaft and the sensor at the bottom of the hook, when the sensor moves past the front of the sensor head, the sensor generates a signal that the rotating shaft rotates one revolution. This allows for accurate detection of the rotation signal of the rotating shaft each revolution. Since the rotating shaft is fixedly connected to the roving roller via a connecting part using a plug or thread, the rotation of the rotating shaft and the rotation of the roving roller are consistent. This achieves accurate detection of the rotation of the roving roller. Compared with the existing technology where there is no means to detect the rotation of the roving roller, this invention enables the monitoring of the rotation of the roving roller, providing an automatic basis and means for judging roving breakage and whether the roving has been used up.

[0015] In this embodiment of the utility model, through the cooperation of the sensing block on the rotating shaft and the sensor at the bottom of the hook, when the sensing block 5 passes in front of the sensing head 2, the sensor 3 generates a signal that the rotating shaft 9 rotates one revolution. It can accurately detect the signal of each revolution of the rotating shaft. Since the rotating shaft is fixedly connected to the roving roller by plugging or threading through the connecting part, the rotation of the rotating shaft is consistent with the rotation of the roving roller. In this way, the rotation of the roving roller is accurately detected. Compared with the prior art where there is no means to detect the rotation of the roving roller, the rotation of the roving roller is monitored, providing a basis and means for automatic judgment of roving breakage and whether the roving has been used up.

[0020] Preferably, the T-shaped head 12 is provided with a fastening head 13, which is used to fasten the shaft and the roving roller together when the connecting part 8 is connected to the roving roller by means of a threaded connection.

[0021] Preferably, the sensing block 5 is fixed to the side of the fastening head 13 or the T-shaped head 12, the sensor 3 is fixed at the position where the hook 1 is directly opposite the sensing block 5, and the sensing head 2 is directly opposite the sensing block 5.

[0022] To fix the sensor 3 at the position where the hook 1 and the sensing block 5 are directly opposite, the sensor 3 can be attached to the inner wall of the U-shaped notch; alternatively, a hole can be drilled in the side wall of the U-shaped notch to serve as a mounting hole for the sensor 3, and the sensor 3 can be fixed in the mounting hole. The wire of the sensor 3 is located on the outside of the hook 1, which facilitates connection with other equipment.

[0023] Preferably, the sensor block 5 is located on the side of the rotating shaft 9 and at the bottom of the base 10. A dust cover 16 is provided on the outside of the hook.

[0027] The implementation of the technical feature that the sensor 3 generates a signal that the rotating shaft 9 rotates one revolution when the sensing block 5 moves past the front of the sensing head 2 includes the following technical means: Hall effect sensor with magnet: A magnet is fixed on the moving part, and the sensor uses Hall element to sense the change in magnetic field when the magnet approaches or moves away from the magnet, and outputs high and low level signals to accurately correspond to the number of rotations or position points. Magnetoresistive sensor detection: Utilizing the characteristic that the resistance of a magnetoresistive element changes with the magnetic field strength, it has a faster response speed than Hall effect sensors and is suitable for detecting signal points that rotate at high frequency or move at high speed. Reed switch triggering: The moving part carries a magnet. When the magnet is close, the reed switch contacts are attracted, and when it is far away, they are disconnected. A signal is generated by the change of the on / off state. It has a simple structure, low cost, and is suitable for low-speed rotation detection. Combination of magnetic scale and magnetic head: The magnetic scale has pre-made equidistant magnetic graduations, and the magnetic head reads the changes in the magnetic field scale and outputs a pulse signal, which is suitable for high-precision displacement or continuous detection of multiple signal points. Inductive magnetic proximity sensor: It generates an alternating magnetic field through a coil. When a magnetic metal part enters the magnetic field range, the coil impedance changes and triggers a signal. It is suitable for detection scenarios with short-range and anti-interference requirements.
