Description

Technical Field

[0001] This utility model belongs to the field of conductive fiber coating equipment, specifically, it relates to a pressure regulating mechanism for a conductive fiber coating machine. Background Technology

[0002] In the conductive fiber coating process, the pressure between the coating rollers directly affects the coating thickness and uniformity. In existing technologies, the pressure adjustment of the coating rollers is mostly achieved using manual screws or hydraulic devices. However, manual adjustment relies on operator experience, which can easily lead to pressure fluctuations, affecting coating quality. Traditional mechanisms lack pressure monitoring functions, requiring machine shutdown for measurement, resulting in low efficiency. Vibration during the coating process can easily cause the adjustment mechanism to loosen, leading to pressure deviations and difficulties in synchronizing multiple springs or hydraulic cylinders, resulting in uneven roller surface pressure, insufficient accuracy, lack of real-time feedback, poor stability, and poor synchronization.

[0006] The signal output terminal of the pressure sensor is connected to a display screen on the outside of the frame to display the pressure value in real time.

[0007] As a preferred embodiment, a limiting component is provided between the adjusting arm and the frame. The limiting component includes a guide block fixed to the side wall of the frame and a limiting bolt passing through the guide block. The inner end of the limiting bolt is in close contact with the side of the adjusting arm.

[0008] As a preferred embodiment, a hemispherical protrusion is provided between the pressure sensor and the pressure plate, and the bottom of the hemispherical protrusion is embedded in the groove of the pressure plate.

[0009] As a preferred embodiment, the inner wall of the groove is provided with a silicone damping layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Figure 2 This is a partially enlarged structural diagram of section A of this utility model. Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] A pressure regulating mechanism for a conductive fiber coating machine includes a coating frame 1, an upper coating roller 2 and a lower coating roller 3 disposed inside the frame 1, wherein the two ends of the upper coating roller 2 are connected to adjusting arms 5, and the upper end of the adjusting arm 5 passes through a vertical sliding groove 6 opened on the top of the frame 1.

[0018] The upper end of the adjusting arm 5 is provided with a pressure plate 7, and a vertically arranged adjusting screw 8 is provided above the pressure plate 7. The lower end of the adjusting screw 8 is in contact with the pressure plate 7 through a pressure sensor 9.

[0019] The upper end of the adjusting screw 8 is connected to a worm gear 101, which meshes with a worm 102. One end of the worm 102 is connected to a manual knob 11, and the worm 102 is fixed to the top of the frame 1 by an anti-reverse ratchet mechanism 27. It should be noted that the top of the adjusting screw 8 is connected to the worm gear 101 via a keyway or spline to ensure that the adjusting screw 8 rotates synchronously when the worm gear 101 rotates, but the axial (Z-axis) movement of the adjusting screw 8 is unrestricted. The middle section of the adjusting screw 8 is threadedly connected to a fixing nut located above the frame 1, thus mounting the adjusting screw 8 on the frame. The fixing nut restricts the adjusting screw 8, allowing it to move only up and down.

[0020] Preferably, the meshing surface length of the worm 102 and the worm wheel 101 covers the entire stroke of the adjusting screw 8, ensuring that the worm wheel 101 and worm 102 are always meshed when the adjusting screw 8 is raised or lowered. The helix angle of the worm 102 and the tooth profile of the worm wheel 101 are designed to mesh with the full tooth width, avoiding disengagement due to the raising or lowering of the adjusting screw 8.

[0021] The signal output terminal of the pressure sensor 9 is connected to the display screen 28 on the outside of the frame 1 for real-time display of the pressure value.

[0022] Turning the manual knob 11 drives the worm gear 102, and the worm wheel 101 drives the adjusting screw 8 to rise and fall. Through the pressure plate 7, the adjusting arm 5 moves along the slide groove 6, changing the gap between the upper coating roller 2 and the lower coating roller 3.

[0023] Pressure sensor 9 detects pressure in real time and displays it on display screen 28. The operator can fine-tune knob 11 according to the feedback until the target pressure value is reached.

[0024] The ratchet mechanism 27 prevents the worm gear 102 from reversing, ensuring pressure locking; the worm gear drive has self-locking properties, preventing pressure deviation caused by vibration; the pressure sensor displays the pressure value in real time, avoiding human measurement errors; the anti-reverse ratchet mechanism ensures the position is fixed after adjustment, improving stability.

[0025] In a preferred embodiment, a limiting component is provided between the adjusting arm 5 and the frame 1. The limiting component includes a guide block 13 fixed to the side wall of the frame 1 and a limiting bolt 14 passing through the guide block 13. The inner end of the limiting bolt 14 is in close contact with the side of the adjusting arm 5.

[0026] Loosen the limit bolt 14, move the adjusting arm 5 to the target position, and judge whether the position of the adjusting arm 5 is in place according to the pressure value displayed on the display screen 28. After it is in place, tighten the limit bolt 14 to fix it.

[0027] In a preferred embodiment, a hemispherical protrusion 21 is provided between the pressure sensor 9 and the pressure plate 7. The bottom of the hemispherical protrusion 21 is embedded in the groove 22 of the pressure plate 7, and the inner wall of the groove 22 is provided with a silicone damping layer 23.

[0028] The hemispherical protrusion 21 can reduce contact surface friction and avoid pressure transmission deviation; while the silicone damping layer 23 absorbs vibration and improves the measurement accuracy of the sensor.

[0029] In a preferred embodiment, the worm gear 102 is provided with limiting blocks 24 at both ends. The limiting blocks 24 are fixed to the top of the frame 1 by bolts, and the inner side of the limiting blocks 24 is provided with dovetail grooves that slide with the worm gear 102.

[0030] The dovetail groove slides into the worm 102, limiting the radial offset of the worm 102 and ensuring the meshing accuracy of the worm wheel 101 and the worm 102.

[0031] In a preferred embodiment, the manual knob 11 is fitted with an anti-slip rubber sleeve 26 on its outer side. The surface of the anti-slip rubber sleeve 26 is provided with equally spaced annular raised textures to increase the operating friction, prevent hand slippage, and improve adjustment safety.

[0032] The overall workflow of this device is as follows:

[0033] Initialization: Set the target pressure value via display screen 28 and check if the limit bolt 14 is loose;

[0034] Coarse adjustment: Turn the manual knob 11 to drive the worm gear 102 and initially position the adjusting arm 5;

[0035] Fine-tuning: Based on the feedback from pressure sensor 9, fine-tune knob 11 to the target pressure;

[0036] Locking: Tighten the limit bolt 14 and activate the ratchet mechanism 27 to lock the worm gear 102 to prevent pressure deviation;

[0037] Operation monitoring: During the coating process, the display screen 28 shows the pressure value in real time, and an alarm is automatically triggered when the limit is exceeded.

[0038] The action flow example is as follows:

[0039] Pressurization: Rotate the manual knob 11 to drive the worm gear 102 to rotate → the worm wheel 101 drives the adjusting screw 8 to descend → the pressure plate 7 presses down the upper end of the adjusting arm 5 → the adjusting arm 5 moves down along the slide 6 → the upper coating roller 2 presses down the lower coating roller 3. The pressure sensor 9 monitors the pressure value in real time and provides feedback through the display screen 28. The operator can then fine-tune the pressure to the target pressure.

[0040] Pressure reduction: Rotate knob 11 in the opposite direction → Adjusting screw 8 rises → Pressure plate 7 releases pressure → Upper coating roller 2 moves upward under the action of spring or its own weight, and adjusting arm 5 moves upward along slide 6.

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.
