[0025] Figure 1 This is a schematic structural diagram of the initial state of the device for preventing wire drawing center deviation in the present invention;

[0026] Figure 2 This is a schematic diagram of the structure of the device for preventing the center deviation of the wire drawing in the present invention under the state of the hose being pushed Figure 1 ; Figure 3 This is a schematic diagram of the structure of the device for preventing the center deviation of the wire drawing in the present invention under the condition of the hose being pushed Figure 2 , see Figures 1 to 3As shown, a preferred embodiment is shown, which shows a device for preventing the center deviation of wire drawing, including a mounting position 1, a pressure sensor 2, a barrel 3, a pushing mechanism 4, a distance meter 5 and a controller. One end of the barrel 3 is connected to one side of the mounting position 1, and one end of the barrel 3 is also provided with a pressure sensor 2, and the pressure sensor 2 is located between the barrel 3 and the mounting position 1. One side of the other end of the barrel 3 is provided with a distance meter 5, and the distance between the surface of one side of the other end of the barrel 3 and the distance meter 5 is d1. The other side of the barrel 3 is provided with a pushing mechanism 4, and the pushing mechanism 4 is used to push the hose 6 to slide on the barrel 3. The pressure sensor 2, the pushing mechanism 4 and the distance meter 5 are electrically connected to the controller respectively. When the hose 6 is sleeved on the other end of the barrel 3, the distance between the outer edge of the hose 6 and the distance meter 5 is d2. In this embodiment, as Figure 1 As shown, the barrel 3 is fixed to a mounting position 1, which can be a mounting plate or wall. A fixed shaft connected to the mounting position 1 is provided at one end of the barrel 3. A pressure sensor 2 is disposed at one end of the barrel 3, between the barrel 3 and the fixed shaft. A distance meter 5 is located on one side of the other end of the barrel 3, with a push mechanism 4 and distance meter 5 located on either side of the barrel 3. The pressure sensor 2 is used to measure whether the hose 6 is properly installed, while the distance meter 5 is used to measure whether the hose 6 is properly installed on the barrel 3. In the initial state (stopped), the distance meter 5 measures d1, and the position on the barrel 3 opposite the distance meter 5 is not occupied. When in use, with the hose 6 installed at the other end of the barrel 3, the distance meter 5 measures d2, where d2 is less than d1. When the distance meter 5 detects that the hose 6 is in place on the barrel 3, it indicates that the hose 6 is not properly installed. The controller then controls the push mechanism 4 to move the hose 6 toward the pressure sensor 2, forcing it to rest firmly against it. When the pressure sensor 2 measures F2 ≥ 10 N, the controller controls the push mechanism 4 to return to its original position, where the pressure sensor 2 measures F1 = 0 N. The interaction between the push mechanism 4, distance meter 5, and pressure sensor 2 automatically adjusts the position of the hose 6 on the barrel 3, preventing center deviation caused by machine head vibration or operator error, thereby ensuring product quality.

[0027] As a further preferred embodiment, the pushing mechanism 4 includes a motor 41, a ball screw assembly 42, and a push rod 43. The motor 41 is located on the other side of the mounting position 1, and the ball screw assembly 42 is located on the other side of the barrel 3. One end of the ball screw assembly 42 is connected to the motor 41, and the other end of the ball screw assembly 42 is rotatably provided with a push rod 43. The push rod 43 is used to push the hose 6 to slide on the barrel 3. The motor 41 is electrically connected to the controller. In this embodiment, the motor 41 is a stepper motor 41, which is used to drive the ball screw assembly 42 to move linearly, thereby driving the push rod 43 to push the hose 6 toward a position close to the pressure sensor 2.

[0028] As a further preferred embodiment, the push rod 43 is in an arc-shaped structure.

[0029] As a further preferred embodiment, the ball screw assembly 42 includes a screw and a nut mounted thereon. The screw is connected to the motor 41, and the push rod 43 is connected to the nut. In this embodiment, the ball screw assembly 42 is a conventional structure that converts the rotational motion of the screw into the linear motion of the nut, thereby driving the linear motion of the push rod 43.

[0030] As a further preferred embodiment, the device further includes a drive mechanism, the drive mechanism being provided on the nut and connected to the push rod 43 for driving the push rod 43 to rotate 90°. The drive mechanism is electrically connected to the controller. In this embodiment, the drive mechanism is a rotary motor 41 that can drive the push rod 43 to rotate 90° in both forward and reverse directions. During use, when the data detected by the rangefinder 5 is d2, the controller first controls the drive mechanism to rotate the push rod 43 90°, causing the push rod 43 to cover the end face of the hose 6. The controller then controls the motor 41 to drive the screw to move the nut linearly, causing the nut to drive the push rod 43 to push the hose 6 toward the pressure sensor 2. The push rod 43 is configured in an arc shape to facilitate the push rod 43 covering the end face of the hose 6 and facilitate the movement of the hose 6.

[0031] As a further preferred embodiment, the axis of the barrel 3 is perpendicular to the installation position 1.

[0032] The following describes a preferred method for using the device for preventing wire drawing center deviation of the present application, which method includes:

[0033] S1. In the initial state, the data measured by the rangefinder 5 is d1, and the data measured by the pressure sensor 2 is F1=0N;

[0034] S2. Then, the hose 6 is sleeved on the outer edge of the other end of the barrel 3. At this time, the data measured by the distance meter 5 is d2. The distance meter 5 outputs a control signal to the controller. The controller first controls the drive mechanism to drive the push rod 43 to rotate 90 degrees. The controller then controls the motor 41 to drive the ball screw assembly 42 to drive the push rod 43 to push the hose 6, so that the hose 6 moves in the direction close to the pressure sensor 2.

[0035] S3, the hose 6 squeezes the pressure sensor 2, the data F2 measured by the pressure sensor 2 is ≥ 10N, the pressure sensor 2 sends a signal to the controller, the controller controls the driving mechanism to drive the push rod 43 to reset, and the controller controls the motor 41 to drive the ball screw assembly 42 to reset;

[0036] S4. Repeat the above steps S2-S3 until the barrel 3 is filled with the hose 6. In this embodiment, when there is no hose 6 at the other end of the barrel 3, the distance between the distance meter 5 and the barrel 3 is d1. When the operator places the hose 6 at the other end of the barrel 3, the distance between the distance meter 5 and the hose 6 is d2. However, the push rod 43 on the pushing mechanism 4 automatically rotates 90 degrees, pushing the hose 6 inward. When the hose 6 reaches the bottom, it contacts the pressure sensor 2. The pressure sensor 2 measures data F ≥ 10N, and the pushing mechanism 4 stops pushing inward and immediately returns to the position at the other end of the barrel 3 and returns to the shutdown state. At this time, the pressure sensor 2 measures data F2 The force is 0 N. However, when the operator inserts a second hose 6, the distance meter 5 detects the change in distance. The push rod 43 in the pushing mechanism 4 automatically rotates 90°, pushing the second hose 6 inward. When the hose 6 reaches the bottom and contacts the pressure sensor 2, the pressure sensor 2 measures F ≥ 10 N. At this point, the pushing mechanism 4 stops pushing inward and immediately returns to the other end of the barrel 3, returning to the idle state. This continues until all hoses 6 are installed. When all hoses 6 are in their designated positions, the distance meter 5 detects a distance of d1, and the machine automatically returns to the idle state. The distance meter 5 is placed next to the outermost hose 6. If the standby head shakes or an operator error causes the hose 6 to be out of its designated position, the distance meter 5 detects a change from d1 to d2, causing the pushing mechanism 4 to activate and push the hose 6 to its designated position. In this embodiment, the push rod 43 does not rotate 90° when in the idle state, which does not affect the normal installation of the remaining hoses 6.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
