[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a coating blade for machine coating, including a blade body 1, and a right-side fixing structure 2 and a left-side fixing structure 3 that fix the two ends of the blade body 1 respectively. A bayonet 11 is provided on the right side of the blade body 1. A locator 25 is provided in the right-side fixing structure 2 for preliminary positioning of the right end of the blade body 1 through the bayonet 11. A calibration structure 4 that can be elastically extended and retracted and installed on the left-side fixing structure 3 is provided on the left side of the blade body 1. One end of the left side of the blade body 1 can rotate relative to the locator 25. One end of the right side of the blade body 1 is calibrated to be horizontal through the calibration structure 4.

[0026] Please see Figure 2 The bayonet 11 has an open U-shaped groove structure.

[0027] Please see Figure 3 The right-side fixing structure 2 includes a right-side base 21, a right-side pressure cover 22 fixed to the top of the right-side base 21 by a right-side fixing bolt 23, and a right-side threaded rod 24 threaded to the right-side pressure cover 22. The right-side base 21 has a right-side waist-shaped groove 211 for the right end of the blade 1 to pass through and for adjusting the height of the blade 1. The side of the right-side base 21 has a strip groove 212 for guiding the locator 25. A scale plate 26 is fixed on the surface of the right-side base 21 on one side of the strip groove 212. The right side adopts a bayonet 11 + locator 25 structure to achieve initial positioning of the right end of the blade 1. The scale plate 26 and the strip groove 212 on the right side cooperate with the movement of the locator 25 to provide a precise height adjustment reference.

[0028] Please see Figure 4 The positioner 25 includes a U-shaped slide 251. A slider 252 that is slidably connected to the strip groove 212 is fixed on the side of the U-shaped slide 251. The U-shaped slide 251 is elastically connected to the right base 21 by a first spring 27. A positioning shaft 253 that is adapted to the width of the bayonet 11 is fixed on the inner bottom of the U-shaped slide 251. A positioning protrusion 254 is provided at the center of the end face of the positioning shaft 253.

[0029] Please see Figure 2 The calibration structure 4 includes a stop bar 41. A notch 12 is provided on the left side of the cutter body 1. A guide strip 13 is fixed inside the notch 12 and is arranged along the length of the cutter body 1. The stop bar 41 is slidably connected to the guide strip 13. A bubble tube 42 is fixedly embedded on the top surface of the stop bar 41. A guide rod 43 is fixed on one end of the inner side of the stop bar 41. A telescopic hole 14 is opened on one side of the notch 12 and slides with the guide rod 43. A second spring 44 is sleeved on the guide rod 43. The stop bar 41 is elastically connected to the cutter body 1 through the second spring 44. The calibration structure (bubble tube 42 + guide strip 13 + second spring 44) is designed on the left side. The horizontal state of the cutter body 1 can be intuitively judged by the bubble being centered, so as to realize the posture calibration of the cutter body 1. The bubble tube 42 on the left side provides visual feedback on the horizontal state. The combination of the two significantly improves the installation efficiency and accuracy.

[0030] Please see Figure 5 The left fixed structure 3 includes a left base 31, a left pressure cover 32 fixed to the top of the left base 31 by a left fixing bolt 33, and a left threaded rod 34 threaded to the left pressure cover 32. The left base 31 has a left waist-shaped groove for the stop rod 41 to pass through. The side of the stop rod 41 is fixed with a semi-circular stop block 45 that abuts against the left base 31. The right side of the blade body 1 is quickly connected to the positioner 25 through the bayonet 11, and the left side achieves elastic extension and retraction through the cut 12 and guide strip 13, simplifying the replacement process.

[0031] The working principle and usage process of this utility model are as follows: When installing the blade body 1, first pass one right end of the blade body 1 through the right waist-shaped groove 211 of the right fixing structure 2, and press the bayonet 11 of the blade body 1 against the positioning protrusion 254 inside the locator 25. By screwing the right threaded rod 24, the lower end of the right threaded rod 24 presses against the U-shaped slide 251, so that the positioning shaft 253 pushes the right end of the blade body 1 to float up and down in the right waist-shaped groove 211 in conjunction with the elastic force of the first spring 27. Thus, the installation height of the blade body 1 can be initially adjusted according to the positioning protrusion 254 at the center of the positioning shaft 253 and the scale value on the scale plate 26 outside the strip groove 212.

[0032] Then, by compressing the stop rod 41, the stop rod 41 is inserted into the left waist-shaped groove 311 of the left base 31. By screwing the left threaded rod 34, the lower end of the left threaded rod 34 presses down on the stop rod 41. Then, through the sliding extension and retraction of the guide rod 43 and the elastic force of the second spring 44, the left end of the blade body 1 floats up and down, so that the bubble position of the bubble tube 42 at the top of the stop rod 41 is centered, thereby adjusting the blade body 1 to a horizontal position, so that the two ends of the blade body 1 are kept at the same horizontal height.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
