Abstract
Description
Technical Field
[0001] This application relates to the field of rolling mills, and more particularly to a highly adaptable rolling mill. Background Technology
[0002] The rolling mill is one of the most widely used and numerous general-purpose unit machines in the printing and dyeing machinery. According to its use in the printing and dyeing process, it can be divided into two main categories: water rolling mill and dyeing rolling mill; according to its form, it can be divided into three types: vertical, horizontal and inclined.
[0003] Currently, Chinese utility model patent CN208949545U discloses a small rolling mill, including a rolling mill body, an active rolling mill roll, a driven rolling mill roll, two columns, and a motor. The columns are vertically mounted on the upper surface of the rolling mill body and arranged parallel to each other. The motor is mounted on one of the columns. The active and driven rolling mill rolls are connected between the two columns, with the driven rolling mill roll located above the active rolling mill roll. The active rolling mill roll is driven by the motor. A connecting rod is provided inside the driven rolling mill roll, extending from both ends. The driven rolling mill roll is rotatably fitted onto the connecting rod. Cylinders are provided on the upper surface of each column. Opening slots are provided along the axial direction on the surface of each column near the driven rolling mill roll. The upper end of the opening slot and the end of the opening slot near the driven rolling mill roll are both open. This utility model has the advantage of high reliability.
[0004] When the fabric type is changed, resulting in a change in the thickness of the fabric that the rolling mill needs to process, the distance between the active and driven rollers needs to be readjusted. This is achieved by changing the air source pressure, which in turn changes the extension length of the cylinder piston rod. The adjustment relies on manual experience, and novice operators are prone to parameter fluctuations, leading to unstable batch quality. Utility Model Content
[0005] To facilitate the adjustment of the distance between the driving roll and the driven roll by the operator, this application provides a rolling mill with good adaptability.
[0006] This application provides a rolling mill with good adaptability, which adopts the following technical solution:
[0007] An adaptable rolling mill includes a frame, a drive roll, a driven roll, a motor, and an adjustment assembly. The drive roll is rotatably connected to the frame, and the motor drives the drive roll to rotate. The adjustment assembly includes an adjustment frame, an adjustment screw, a laser rangefinder, and a measuring plate. The adjustment frame is slidably connected to the frame in a direction close to or away from the drive roll. The length direction of the adjustment screw is parallel to the sliding direction of the adjustment frame, and the adjustment screw is rotatably connected to the frame. The adjustment frame is threadedly connected to the adjustment screw. The driven roll is rotatably connected to the adjustment frame. The measuring plate is disposed on the frame, and the laser rangefinder is used to measure the distance from the driven roll to the measuring plate.
[0008] By adopting the above technical solution, when the operator needs to adjust the distance between the driven roll and the driving roll, the operator can rotate the adjusting screw, which moves the adjusting frame, changing the distance between the driven roll and the driving roll on the adjusting frame. The measuring plate is set on the frame, and the distance between the driven roll and the measuring plate can be measured by a laser rangefinder, making it convenient for the operator to make adjustments. This eliminates the need to rely on the operator's experience and allows for precise adjustment of the driven roll position. Furthermore, the adjusting screw has a self-locking effect, ensuring that the distance between the driven roll and the driving roll remains constant during the rolling mill operation, thus improving the reliability of the equipment.
[0009] Optionally, the adjusting frame is further provided with a fine-tuning component, which includes a fine-tuning bracket and a fine-tuning screw. The fine-tuning bracket is slidably connected to the adjusting frame along the length direction of the adjusting screw. The length direction of the fine-tuning screw is parallel to the length direction of the adjusting screw. The fine-tuning screw is rotatably connected to the adjusting frame and threadedly connected to the fine-tuning bracket. The pitch of the fine-tuning screw is smaller than the pitch of the adjusting screw.
[0010] By adopting the above technical solution, the thickness of the fabric is generally between 6 amps and 24 amps, with little difference in thickness. The operator can first adjust the distance between the driven roller and the driving roller by adjusting the screw. When the value of the laser rangefinder is close to the required value, the operator can adjust the fine-tuning screw. The pitch of the fine-tuning screw is smaller than the pitch of the adjusting screw, which makes it easier for the operator to accurately control the distance between the driven roller and the measuring plate, and further improve the adjustment accuracy.
[0011] Optionally, the fine-tuning frame is further provided with a scraping component for scraping off lint from the driven roll. The scraping component includes a receiving box and a scraper. The receiving box is disposed on the fine-tuning frame, and the scraper is disposed on the receiving box. The scraper abuts against the driven roll.
[0012] By adopting the above technical solution, the dye is separated from the fabric under the action of the active roller and the driven roller. At this time, the lint on the fabric will also come into contact with the driven roller. The scraper can scrape off the lint on the driven roller. The driven roller rotates during the movement of the fabric, and the corresponding scraper moves. The scraper can scrape off the lint on the driven roller. The receiving box is used to receive the lint scraped off by the scraper.
[0013] Optionally, the scraper is provided with several guide grooves to guide the lint into the receiving box, and the guide grooves are distributed along the length of the scraper.
[0014] By adopting the above technical solution, the guide groove is used to guide the lint on the scraper into the receiving box. The guide groove reduces the accumulation of lint on the scraper, so that the scraper can smoothly scrape off the lint on the driven roller.
[0015] Optionally, the scraper includes a mounting bolt that passes through the receiving box and is threaded onto the fine-tuning frame.
[0016] By adopting the above technical solution, when there is a large amount of lint in the receiving box and it can no longer receive lint, the staff can unscrew the installation bolts to separate the receiving box from the adjustment frame, so that the staff can collect and process the lint in the receiving box. Then, the receiving box can be installed onto the adjustment frame by using the installation bolts.
[0017] Optionally, the frame is provided with a dyeing tank for receiving dye liquor, and the side wall of the dyeing tank is provided with a discharge pipe for discharging the dye liquor.
[0018] By adopting the above technical solution, the active and driven rollers press the fabric to control the amount and uniformity of dye feeding. Excess dye liquor will enter the dyeing tank, and the discharge pipe is used to discharge the dye liquor in the dyeing tank, thereby collecting and treating the excess dye liquor for subsequent reuse, which is in line with the concept of green environmental protection.
[0019] Optionally, the dyeing tank is equipped with a filter screen to restrict the entry of lint into the dyeing tank.
[0020] By adopting the above technical solution, the filter screen reduces the amount of lint on the fabric that enters the dye bath along with the dye, thereby improving the purity of the dye solution in the dye bath.
[0021] Optionally, the filter screen is provided with a reinforcing edge on its periphery, and a hook is provided on the reinforcing edge for hooking onto the side wall of the dyeing tank.
[0022] By adopting the above technical solution, excess dye on the fabric will continuously impact the filter screen. Strengthening the edges can improve the strength of the filter screen. When there is too much lint on the filter screen, the staff will remove the filter screen from the dyeing tank, process the lint on the filter screen, and then install the filter screen onto the side wall of the dyeing tank through hooks for subsequent lint filtration.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] The adjusting screw changes the position of the adjusting frame to adjust the distance between the driven roller and the driving pressure roller. The distance between the driven roller and the measuring plate is measured by a laser rangefinder, which facilitates precise adjustment by the operator.
[0025] The fine-tuning component further improves the adjustment accuracy and speed of the driven roll;
[0026] The scraper is used to remove lint from the driven rolls. Attached Figure Description
