A hose reel device with slow hose take-up function

Abstract

This system employs an MCU combined with Hall effect sensors to accurately measure the number of revolutions. A dual detection mechanism—remaining revolution prediction and motor current change detection—works collaboratively to improve the reliability of the tube-taking control. At the end of the tube-taking process, the system automatically switches to a low-speed operating mode, monitoring motor current changes in real time. When a sudden increase in stall current caused by the remote control ball contacting the tube outlet is detected, emergency braking is immediately triggered. A dual-parameter cross-validation mechanism effectively reduces the false alarm rate, and the dual safety protection design ensures operator safety. This system achieves fully closed-loop intelligent control of the tube-taking process, significantly improving equipment safety and lifespan while maintaining work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of electric hose reel technology, and in particular to a hose reel device with a slow hose winding function. Background Technology

[0002] Traditional electric hose reels use high speeds for the entire hose winding process, which ensures high work efficiency but also results in a high rate of mechanical limit damage. While low-speed winding provides mechanical impact, it significantly reduces work efficiency and fails to meet practical application requirements.

[0003] Traditional stall detection methods rely on current or torque feedback, resulting in significant response delays. Over time, the flexible tubular structure is prone to mechanical damage due to excessive stretching, the motor is also damaged due to frequent stalling, and the casing is inevitably deformed by compression.

[0004] Traditional electric hose reels lack the ability to accurately measure the distance to the end of the hose and cannot dynamically adjust the motor speed, forcing a trade-off between production efficiency and equipment maintenance. Existing technology uses mechanical limit impacts on the housing to achieve physical limitation, which makes it difficult to achieve efficient hose reeling while protecting the hose reeling device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a hose reel device with a slow hose take-up function.

[0006] This utility model provides a hose reel device with a slow-speed hose take-up function, comprising: A hose reel device with a slow-speed reeling function, comprising a large turntable, a motor, a housing, and a remote-controlled ball, wherein the large turntable is drivenly connected to the motor; the large turntable is used to wind and connect a flexible tube, characterized in that the hose reel device with the slow-speed reeling function includes: Magnetic components are installed on one side of the large turntable; A Hall sensor is fixed to the housing and faces the large turntable, corresponding to the rotation path of the magnetic component; The remote-controlled ball is fitted into a flexible tube and extends out of the conduit opening of the shell; The MCU controller receives the electrical signal output by the Hall sensor detected by the magnetic component, counts the number of revolutions, and outputs a signal to control the motor to decelerate or stop its movement according to the set threshold.

[0007] In one embodiment, the large turntable is characterized by having baffles on both sides, and the magnetic component is installed on one of the baffles.

[0008] In one embodiment, the magnetic element comprises a plurality of magnetic elements, which are located on the same circumference and are evenly distributed.

[0009] In one embodiment, the magnetic element is embedded in the baffle.

[0010] In one embodiment, the baffle is characterized by having multiple intersecting reinforcing ribs distributed on its outer side, and the magnetic element filling one of the enclosed areas of the reinforcing ribs.

[0011] In one embodiment, the housing is characterized by being divided into left and right parts, which, when assembled, enclose the large turntable and the motor inside.

[0012] In one embodiment, the Hall sensor is located inside a large turntable.

[0013] In one embodiment, the housing partially protrudes and extends into the large turntable, and the Hall sensor is mounted on the protruding part of the housing.

[0014] In one embodiment, the remote-controlled ball has a diameter larger than the conduit opening.

[0015] The advantages of this invention compared to the prior art after adopting the above structure are: The control method uses an MCU and Hall effect sensors to calculate the number of turns, enabling precise control of the tube take-up. By employing both remaining turn prediction and current change data to determine the take-up progress, the false alarm rate is reduced, mitigating the impact of the mechanical limit switch while maintaining operational efficiency.

[0023] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0024] like Figure 1 As shown, the tube reel includes a large turntable and a housing. One side of the large turntable is fixed to the right housing, and the other end of a motor, which is driven by the large turntable, passes through a pre-drilled hole in the housing. Magnetic material is filled onto the large turntable.

[0025] like Figure 2 and Figure 4 As shown, two baffles are provided on both sides of the large disc. One side of the baffle adopts a concentric circle design of inner diameter ribs, middle ribs, and outer diameter ribs, which intersects with multiple radial reinforcing ribs to form a grid structure, significantly improving the overall strength of the disc. The magnetic components are preferably filled in the grid units between the inner diameter ribs and the middle ribs. This arrangement not only shortens the rotation circumference but also provides more installation position options.

[0026] like Figure 2 , Figure 5 and Figure 6 As shown, the Hall sensor is mounted in the recessed center of the housing. Optionally, the Hall sensor can be glued or embedded in the housing. A preferred solution is to have two ribs pre-installed on the housing, symmetrically arranged, each with a small groove in the middle for mounting the Hall sensor. This not only facilitates installation and replacement but also prevents the Hall sensor from shaking or being squeezed. Furthermore, the rib mounting position must be closely aligned with the magnetic component to ensure accurate and real-time sensing.

[0027] like Figure 3 As shown, a housing cover is also installed on the outer casing to protect the internal components. The raised part in the middle of the housing cover is ergonomically designed for easy installation and removal.

[0028] When the motor begins the tube-making motion, the magnetic material rotates accordingly. A Hall sensor detects the magnetic signal generated by the magnetic material and sends it to the MCU controller, which then starts counting the number of tube turns. Similarly, when the tube-retracting motion begins, the MCN controller starts counting the number of tube turns. When the difference between the number of tube turns made out and the number of turns made in is less than a set value, the motor begins to decelerate, activating the slow tube-retracting mode. This set value can be automatically set based on the roller diameter and the diameter of the flexible tube.

[0029] Optionally, multiple magnetic objects can be filled at uniform intervals along the same circumference. For example, with four magnetic objects, the Hall sensor detects four objects per revolution. When the remaining number of revolutions is less than a set threshold, the speed can be gradually reduced until it stops, based on the number of magnetic objects detected. For example, the speed decreases by a certain percentage when the first magnetic object is detected, and so on, stopping when the last magnetic object is detected. Using multiple magnetic objects allows for more accurate counting of revolutions; for example, filling with four magnetic objects can accurately detect a quarter revolution, and filling with eight magnetic objects can accurately detect one-eighth of a revolution.

[0030] like Figure 1 As shown, the remote-controlled ball can be fixedly installed at the end of the flexible tube, preferably at a certain distance from the tube opening. When the tube winding action reaches the end, the remote-controlled ball acts as a mechanical limit to prevent the tube winding machine from overwinding.

[0031] While the tube is slowly retracting, the current is monitored in real time. If the remote-controlled ball at the end touches the tube outlet, the stall current will increase instantly, and the motor will immediately stop retracting the tube. This avoids damage to the casing caused by the remote-controlled ball hitting the casing and also prevents personal injury.
