Description

Technical Field

[0001] This utility model relates to the field of metallurgical coating equipment technology, specifically a metering roller assembly for an automatic zeroing and fine-tuning mechanism on a silicon steel roller coating machine. Background Technology

[0002] Driven by both new energy and energy efficiency upgrades, the demand for high-end silicon steel materials is gradually expanding. In recent years, China has seen a surge in new silicon steel projects, leading to a corresponding increase in demand for roll coating machines for silicon steel strips. Some traditional two-roller roll coating machines have emerged in the market, employing a spray coating followed by two-roller drying. These machines primarily produce low-grade, low-quality, and thicker silicon steel. High-grade and high-quality silicon steel coating still relies on three-roller roll coating machines with a novel structure to achieve optimal coating quality. For 0.1mm-0.5mm thick silicon steel strips, existing roll coating machines cannot meet coating precision requirements, mainly due to the following shortcomings: 1. Most existing roll coating machines lack metering rollers, resulting in inconsistent coating uniformity and thickness accuracy, leading to low yield rates; 2. Existing structures cannot ensure a unified control mode with the mechanical structure, causing a decrease in positioning accuracy after prolonged operation; 3. Because the metering rollers are constructed of steel rollers and operate in an intermittent mode with the feed rollers, relying solely on servo motor adjustments can easily damage the roller surface. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a metering roller assembly for an automatic zeroing and fine-tuning mechanism to meet the requirements of coated silicon steel strip.

[0004] To achieve the above-mentioned objectives, this utility model provides a metering roller assembly for an automatic zeroing and fine-tuning mechanism, comprising a metering roller component, a metering roller adjustment mechanism, and a metering roller spring mechanism. The metering roller component is mounted on the equipment stand via a linear guide rail on a metering roller sliding base plate at its bottom. The metering roller sliding base plate at the bottom of the metering roller component is slidably connected to the linear guide rail. A metering roller adjustment push plate is mounted on the lower part of the metering roller sliding base plate. The metering roller adjustment mechanism controls the gap between the metering roller component and the feeding roller by controlling the left and right movement of the metering roller adjustment push plate at the lower part of the metering roller sliding base plate. The metering roller adjustment mechanism is mounted on the left side of the metering roller adjustment push plate and fixed to the inner mounting surface of the equipment stand. The metering roller spring mechanism is mounted on the right side of the metering roller adjustment push plate and fixed to the end face of the equipment stand.

[0005] Furthermore, the metering roller component comprises a metering roller, a metering roller bearing seat, a metering roller bearing seat connecting plate, a metering roller sliding base plate, a metering roller sliding base plate linear guide rail, and a metering roller adjusting push plate. The two ends of the metering roller shaft are mounted on the metering roller bearing seat. A metering roller bearing seat connecting plate for leveling the metering roller is installed between the metering roller bearing seat and the metering roller sliding base plate. A metering roller sliding base plate linear guide rail is installed under the metering roller sliding base plate and sits on the equipment frame. A metering roller adjusting push plate is connected to the middle of the bottom of the metering roller sliding base plate and extends from the opening of the equipment frame into the interior of the equipment frame.

[0006] Furthermore, the metering roller adjustment mechanism consists of a servo motor, a precision gearbox, a bearing mounting base, a connecting rotating shaft, an angular contact ball bearing, a lip seal, a precision locking nut, a bearing cap, a ball screw, a nut mounting plate, a linear guide, and a top plate. The servo motor is connected to the precision gearbox as the power output. The output shaft of the precision gearbox is fixedly connected to one end of the connecting rotating shaft. An angular contact ball bearing is installed on the outer side of the connecting rotating shaft and locked with a precision locking nut. Both ends of the angular contact ball bearing are sealed with lip seals. The right side of the precision gearbox is connected to the bearing mounting base, which is fixed to the inner side of the frame. A bearing cap is installed at the right end of the bearing mounting base. The other end of the connecting rotating shaft is connected to the ball screw. The nut on the ball screw is connected to the nut mounting plate. A linear guide is provided on the upper part of the nut mounting plate to guide the forward and backward movement of the nut mounting plate. The linear guide is fixed on the equipment frame. A top plate is fixed on the nut mounting plate, and the top plate moves the metering roller adjustment push plate.

[0007] Furthermore, the metering roller spring mechanism consists of a spring top, a pressure sensor, a spring intermediate shaft, a spring guide plate, a spring mounting base, an adjusting copper sleeve, and a spring. The spring mounting base is fixed to the end face of the equipment frame. Two adjusting copper sleeves are installed inside the spring mounting base. The spring intermediate shaft is installed inside the adjusting copper sleeves. The spring guide plate is fixed on the spring intermediate shaft. The spring is installed on the spring guide plate and the spring mounting base. The inner ring of the pressure sensor is fixed to the left end of the spring intermediate shaft. The outer ring of the pressure sensor is connected to the spring top with screws. The spring top presses against the metering roller adjusting push plate.

[0008] Compared with the prior art, this utility model has the following advantages: 1. The metering roller adjustment mechanism is not directly connected to the metering roller bearing seat. Instead, it controls the gap between the metering roller and the take-up roller by pushing the metering roller adjustment push plate. This avoids the generation of large pressure on the metering roller and the take-up roller during operation, which would damage the roller surface of the metering roller and the take-up roller.

[0009] 2. The metering roller and the feeding roller operate in a gap mode. The metering roller adjustment mechanism has higher gap adjustment accuracy. When the metering roller adjustment mechanism retracts, the metering roller spring mechanism can automatically zero the gap between the metering roller and the feeding roller.

[0010] 3. The pressure sensor in the metering roller spring mechanism has a stable reading during normal operation. When a problem occurs during operation, the pressure will change, which can remotely determine the equipment failure. Attached Figure Description

The metering roller adjusting push plate 10 is connected to the middle of the bottom of the metering roller sliding base plate 8 and extends from the opening of the equipment archway 4 into the interior of the equipment archway 4.

[0019] Preferably, the metering roller adjustment mechanism 2 is mainly composed of a servo motor 12, a precision gearbox 13, a bearing mounting base 14, a connecting rotating shaft 15, an angular contact ball bearing 16, a lip seal 17, a precision locking nut 18, a bearing cover 19, a ball screw 20, a screw nut mounting plate 21, a linear guide rail 22, and a top plate 23.

The metering roller spring mechanism 3, with preload, is installed on the end face of the equipment frame 4. The pressure sensor 25 displays... The initial pressure is the preload of spring 30. The preload of metering roller spring mechanism 3 will make metering roller 5 close to picking roller 11 when it is at zero position. The distance that metering roller adjustment mechanism 2 pushes metering roller adjustment push plate 10 is the gap between metering roller 5 and picking roller 11. This gap can be precisely controlled by metering roller adjustment mechanism 2 to make metering roller 5 and picking roller 11 operate in a higher precision gap mode. When metering roller adjustment mechanism 2 retracts, metering roller spring mechanism 3 can automatically zero the gap between metering roller 5 and picking roller 11.
