Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a coating scraper box pressure monitoring system. Background Art

[0002] Lithium battery separator production line refers to a series of equipment and process flow used to produce lithium battery separators. The separator is an important component of lithium batteries. It can isolate the positive and negative electrodes to prevent short circuits, while allowing lithium ions to pass through to achieve battery charging and discharging. The quality and performance of the separator directly affect the safety, cycle life and energy density of lithium batteries. When coating lithium battery separators, separator coating machines are often required.

[0003] Some diaphragm coating machines are now equipped with coating scraper boxes, but most of the boxes on the market are pre-tightened by cylinders and adjusted by handwheel screws. The distance between the scraper box displacement and the coating roller contact is often monitored by a displacement sensor. However, the position sensor can only ensure that the scraper can contact the coating roller when it is not worn during initial use. After long-term use, the scraper will gradually wear out, causing the product to deviate from the coating roller due to scraper wear, resulting in a poor coating effect. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 The coating scraper material box pressure monitoring system includes a fixed seat 1, a slide rail 11 is arranged on the upper surface of the fixed seat 1, a sliding seat 2 is slidably arranged on the slide rail 11, a coating scraper material box 001 is installed on the front side of the sliding seat 2, the sliding seat 2 includes a slider 21, the slider 21 is slidably arranged on the slide rail 11, a mounting plate 22 is arranged on the upper surface of the slider 21, the slider 21 is on the slide rail 11, so that the sliding seat 2 can move on the fixed seat 1.

[0024] An adjustment and protection box 23 is provided on the upper surface of the mounting plate 22, and a spacing fine-adjustment mechanism 6 is installed on the adjustment and protection box 23. A flipping mechanism 3 is provided on the upper surface of the mounting plate 22, located on one side of the adjustment and protection box 23. A connecting seat 4 is installed on the front side of the flipping mechanism 3. A pressure sensor 5 is installed on the other side of the connecting seat 4 away from the flipping mechanism 3. The pressure sensor 5 is connected and installed with the coating scraper material box 001. The pressure sensor 5 can monitor the pressure of the blade pressing on the coating roller in real time.

[0025] Among them, a cylinder 12 is installed on the side wall of the bottom inner cavity of the fixed seat 1 box, and a cylinder connecting seat 13 is connected to the push rod on the output end of the cylinder 12. The top of the cylinder connecting seat 13 is fixedly connected to the slider 21. The cylinder 12 is convenient for pushing the cylinder connecting seat 13, so that the slider 21 slides on the slide rail 11.

[0026] In addition, a connecting plate 14 is provided on the upper surface of the fixing seat 1 and located in front of the sliding seat 2 .

[0027] Among them, the spacing fine-adjustment mechanism 6 includes a driving motor 61, a threaded rod 62 is connected to the output end of the driving motor 61, the threaded rod 62 is vertically arranged in the adjustment protection box 23, and a movable head 63 is installed at the bottom of the threaded rod 62. The threaded rod 62 cooperates with the drive of the driving motor 61 to drive the movable head 63 to move up and down.

[0028] Among them, a laterally movable pushing rod 7 is arranged in the cavity located on one side of the movable head 63 in the adjusting protection box 23, and the pushing rod 7 can contact with the connecting plate 14. The movable head 63 includes a pushing block 631 arranged at the bottom, and the wall surface on one side of the pushing block 631 is composed of a plane and an inclined surface. The pushing block 631 contacts with the pushing rod 7 on one side. Through the contact between the vertical plane of the movable head 63 and the inclined surface and the pushing rod 7, the movable head 63 can push the pushing rod 7 to move.

[0029] In addition, a ball bearing 71 is rotatably arranged in a groove at one end of the pushing rod 7, and one side surface of the pushing block 631 is in contact with the ball bearing 71. A spherical head 72 is provided at the other end of the pushing rod 7 away from the ball bearing 71. The spherical head 72 is in contact with the connecting plate 14. The spherical head 72 can push the connecting plate 14, so that the sliding seat 2 can be fine-tuned on the fixed seat 1, thereby ensuring that the scraper can always be in contact with the coating roller.

[0030] In this embodiment, first, the cylinder connecting seat 13 is pulled by the piston rod of the cylinder 12, so that the cylinder connecting seat 13 drives the slider 21 to move on the slide rail 11, so that the coating scraper box 001 installed on the sliding seat 2 contacts the coating roller, and the scraper blade on the coating scraper box 001 fits the anilox coating roller, and the pressure sensor 5 is set to zero position, and a PLC is set to control the drive motor 61. When the pressure sensor feedback finger changes, automatic adjustment is made to realize a pressure closed loop.

[0031] When the spacing fine-tuning mechanism 6 is fine-tuning the spacing, the driving motor 61 drives the threaded rod 62 to rotate, so that the movable head 63 can move up and down. When the movable head 63 moves, the pushing rod 7 on one side plays a limiting role. When the movable head 63 moves, the ball bearing 71 will roll on the side wall of the movable head 63. When the coating scraper box 001 needs to be fine-tuned forward, the movable head 63 moves upward. At this time, the ball bearing 71 will roll from the original plane to the inclined surface below, so that the pushing rod 7 can be pushed by the movable connecting plate 14 driven by the cylinder 12, so that the sliding seat 2 as a whole can be fine-tuned forward. In this process, it stops as the pressure value decreases, thereby ensuring that the scraper will always contact the coating roller.

[0032] In the utility model, a pressure sensor is arranged between the sliding seat 2 and the coating scraper material box 001 provided with the scraper, so that the pressure after the blade contacts the coating roller can be monitored in real time, and the distance between the front and the back can be slightly adjusted by the arranged spacing micro-adjustment mechanism 6, so as to keep the scraping size of the blade consistent and compensate for the blade wear, thereby improving the consistency of the produced products.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
