AI Technical Summary
Existing coating mechanisms struggle to achieve fine and precise adjustments when regulating the height of the scraper roller, especially when high coating thickness is required. Simply relying on screw thread adjustment methods is insufficient to meet the accuracy requirements.
The coating test bench uses a drive mechanism to move the frame back and forth. The design of the slide table and inclined support block, combined with the threaded connection between the screw and the slide table, allows for height adjustment of the scraper. A dial indicator is also provided for real-time measurement to ensure the accuracy and convenience of adjustment.
It enables fine and convenient adjustment of the squeegee height, improves the precise control of coating thickness, and meets the requirements of high-precision coating.

DETAILED DESCRIPTION
[0017] The following will be described in detail in combination with the accompanying drawings. Figures 1-2 The present application will be further described in detail.
[0018] An embodiment of the present application discloses a coating test bench. Referring to Figure 1 and Figure 2, including a coating film table 1 and a rack 2, the first guide rail 16 is arranged on the coating film table 1, the rack 2 is slidably connected to the first guide rail 16, a driving mechanism 4 for driving the rack 2 to slide back and forth is arranged on the coating film table 1, the driving mechanism 4 comprises a first driving motor 41 and a reciprocating screw 42, a nut 43 matched with the reciprocating screw 42 is fixed on the coating film table 1, the reciprocating screw 42 passes through the nut 43 and is matched with the nut 43, a second belt pulley 44 is arranged on the reciprocating screw 42, a third belt pulley 45 is arranged on the output end of the first driving motor 41, and a second belt 46 is sleeved between the second belt pulley 44 and the third belt pulley 45. When the first driving motor 41 is started, the reciprocating screw 42 can be driven to rotate through the second belt 46, and the reciprocating screw 42 can drive the nut 43 and the entire rack 2 to move back and forth after rotating.
[0019] A glue scraping stick 3 is arranged on the rack 2, the cross section of the glue scraping stick 3 is circular, the glue scraping stick 3 is arranged on the rack 2 to slide up and down, a sliding groove 5 for the glue scraping stick 3 to slide up and down is arranged on the rack 2, and an adjusting mechanism 6 for adjusting the height of the glue scraping stick 3 is arranged on the left and right sides of the rack 2. The adjusting mechanism 6 comprises a sliding table 61, a second guide rail 12 is arranged on the rack 2, the sliding table 61 is slidably connected to the second guide rail 12, the sliding direction of the sliding table 61 is the same as that of the rack 2, a supporting block 62 is arranged on the sliding table 61, the sliding table 61 is detachably connected with the supporting block 62 (the supporting block 62 with different angles of inclined surface 63 can be replaced to adapt to more working conditions), and in the scheme, the sliding table 61 is fixedly connected with the supporting block 62 through bolts. The side of the supporting block 62 relative to the glue scraping stick 3 is an inclined surface 63, and the left and right ends of the glue scraping stick 3 are respectively placed on the inclined surfaces 63 of the adjacent supporting blocks 62. A screw rod 64 is rotatably arranged on the rack 2 and threadedly connected with the sliding table 61. When the screw rod 64 is rotated, the sliding table 61 and the supporting block 62 can be driven to move. Since the upper surface of the supporting block 62 is an inclined surface 63, the height of the glue scraping stick 3 placed on the inclined surface 63 can be adjusted after the supporting block 62 moves. Through the cooperation of the screw rod 64, the sliding table 61 and the inclined surface 63, the height can be adjusted more finely and conveniently.

Since the glue scraping stick 3 is cylindrical, if only the measuring head of the dial gauge 7 abuts against the glue scraping stick 3, the movement in the transverse direction will cause inaccurate measurement, and the arrangement of the balance plate 11 makes the measurement result not change even if the dial gauge 7 and the glue scraping stick 3 move in the transverse direction, so that the measurement is more accurate.
[0022] The first pulleys 8 are arranged on the screw rods 64, the first belt 9 is sleeved between the two first pulleys 8, the second driving motor 10 is arranged on the rack 2 and drives one of the screw rods 64 to rotate, the second driving motor 10 is a servo motor, the fourth pulley 13 is fixedly sleeved on one of the screw rods 64, the fifth pulley 14 is fixedly sleeved on the output shaft of the second driving motor 10, and the third belt 15 is sleeved between the fourth pulley 13 and the fifth pulley 14.
