Detailed implementation mode

[0015] The following will further elaborate on the present invention in combination with the embodiments given in the accompanying drawings.

[0016] Refer to Figures 1-4 As shown, a spray gun rack for automatically adjusting the height based on radar sensor ranging includes a first guide rail 1, a spray gun 2 and a spray gun seat 3 mounted on the first guide rail 1. It also includes a sliding seat 4 movably connected to the first guide rail 1, a bottom plate 5 mounted on the sliding seat 4, a sensor assembly 6 mounted on one side of the sliding seat 4 facing the spraying direction of the spray gun 2, a first driving assembly 7 and a second driving assembly 8 mounted on the bottom plate 5. The first guide rail 1 is used for the installation of the spray gun 2 and the sliding seat 4. The sliding seat 4 mounted on the first guide rail 1 can move along the length direction of the first guide rail 1. The sliding seat 4 and the first guide rail 1 are in concave-convex fit and are positioned by being pressed on the first guide rail 1 with bolts. In this embodiment, the bottom plate 5 and the sliding seat 4 are pressed on the first guide rail 1 together with bolts. The second driving assembly 8 is mounted above the first driving assembly 7, and the second driving assembly 8 can move along with the first driving assembly 7. The first driving assembly 7 is used to drive the second driving assembly 8 to move towards the direction of the sensor assembly 6. The sensor assembly 6 includes a screw rod 61, a ball sleeve 62, and a radar sensor 63. The screw rod 61 is threadedly connected to the sliding seat 4, and a ball head 64 ball-jointly connected to the ball sleeve 62 is provided at the end of the screw rod 61. A vertical rod 65 for fixedly connecting the radar sensor 63 is provided on the ball sleeve 62. A connecting rod 9 is provided between the vertical rod 65 and the second driving assembly 8. Both sides of the connecting rod 9 are rotatably connected to the vertical rod 65 and the second driving assembly 8 respectively. The sensor assembly 6 drives the connecting rod 9 to move on the ball head 64 through the second driving assembly 8. The connecting rod 9 is driven by the second driving assembly 8 to push towards the direction of the sensor assembly 6, causing the ball sleeve 62 on the ball head 64 to rotate, so as to adjust the angle of the radar sensor 63 on the first guide rail 1, thereby detecting the distance between the spray gun 2 and the tumbling tablets. Since the fluctuating heights generated by tablets of different sizes and shapes during tumbling are different, the angle of the radar sensor 63 is adjusted during the spraying process of the spray gun 2 to facilitate detecting the distance for tablets of different sizes and shapes, so as to better control the height between the spray gun rack 2 and the tablets, and enable the liquid medicine to be evenly sprayed on the tablets to form an even coating film.

[0017] The first driving assembly 7 includes a driving motor 71, a lead screw 72 mounted on the driving motor 71, a nut seat 73 mounted on the lead screw 72, second guide rails 76 mounted in pairs on the bottom plate 5, and a base 77 movably connected to the second guide rails 76. The base 77 is in concave-convex fit with the second guide rails 76 to facilitate the movement of the base 77 on the second guide rails 76. The driving motor 71 is mounted on the bottom plate 5 and is arranged corresponding to the base 77. An opening 75 for the lead screw 72 to extend out is provided on the base 77, and the opening 75 also allows the nut seat 73 to pass through. The nut seat 73 is fixedly connected to the base 77 through a connecting plate 74. One end of the connecting plate 74 is fixedly connected to the base 77, and the other end of the connecting plate 74 is fixedly connected to the nut seat 73. The nut seat 73 drives the base 77 to move on the second guide rails 76 through the lead screw 72. In this embodiment, limiting seats are fixedly connected to both sides of the second guide rails 76, and the limiting seats are provided to prevent the base 77 from falling out of the second guide rails 76 beyond the maximum stroke.

[0018] The second driving assembly 8 includes an electric push cylinder 81 mounted on the base 77 and a mounting plate 82 for fixing the electric push cylinder 81. One end of the mounting plate 82 is fixedly connected to the base 77, and the other end of the mounting plate 82 is fixedly connected to the electric push cylinder 81. The output shaft of the electric push cylinder 81 is arranged corresponding to the vertical rod 65. The side of the connecting rod 9 away from the sensor assembly 6 is rotatably connected to the output shaft of the electric push cylinder 81. The connecting rod 9 drives the sensor assembly 6 to rotate on the ball head 64 through the electric push cylinder 81. Such a setting enables the spray gun 2 to control the radar sensor 63 to rotate without changing the spraying angle and detect the distance of the tumbling tablets in the coating machine.

[0019] A clamp 10 is sleeved on the connecting rod 9 and is arranged corresponding to the position of the connecting rod 9. The clamp 10 is locked on the connecting rod 9 through a bolt. The connecting rod 9 is rotatably connected to the bolt. The clamp 10 sleeved on the connecting rod 9 can be flexibly installed. During installation, the clamp 10 is set corresponding to the height of the connecting rod 9. The side of the connecting rod 9 for rotational connection is placed at the open end of the clamp 10, and the bolt is inserted from the side of the clamp 10 to make the connecting rod 9 sleeved on the bolt. The other side of the bolt locks the clamp 10 on the vertical rod 65 through a nut for fixation. In this embodiment, the radar sensor 63 is fixedly connected to the vertical rod 65 through a clamping plate 11. The clamping plate 11 and the radar sensor 63 are fixedly connected through bolts.

[0020] The sliding seat 4 includes a first component 41 and a second component 42. The first component 41 and the second component 42 are assembled to form the sliding seat 4. The split setting of the sliding seat 4 facilitates the rapid installation of the sliding seat 4. Bolts for fixing the first component 41 and the second component 42 are provided on the sliding seat 4. Convex portions 43 and concave portions 44 are provided on the mating surfaces of the first component 41 and the second component 42. The convex portions 43 and the concave portions 44 of the first component 41 and the second component 42 are arranged staggeredly. The provision of the mutually cooperating convex portions 43 and concave portions 44 facilitates the rapid installation of the first component 41 and the second component 42.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
