Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a spray gun supporting component of a coating machine. Background Art

[0002] The working principle of the coating machine is to rotate the pot clockwise to make the tablets tumble, slide, rub and grind in the pot, and the spray gun sprays a uniform fine mist of coating liquid on the surface of the tablets. There is also a hot air blower in the coating machine, which blows out hot air to make the coating liquid quickly condense on the surface of the tablets, thus forming coating liquid tablets.

[0003] The spray gun mounting frame of the coating machine in the prior art and the spray gun mounted thereon are mostly pushed in or pulled out along the axial direction of the coating drum, for example, a coating machine with a movable sprayer disclosed in Chinese patent CN208641303U; this method is only applicable to ordinary drum-type coating machines, and is not applicable to coating machines with replaceable coating drums. A front door for the coating drum to enter and exit the machine body is provided on the front wall of the replaceable drum-type coating machine. The coating drum can only be replaced when the front door is opened.

[0038] A support rod 5 is provided at the rear end of the rotating sleeve 3, and a spray gun 6 is provided on the support rod 5;

[0039] When the rotating sleeve 3 is in the first position, the support rod 5 and the spray gun 6 are away from the front door 13 and do not interfere with the opening or closing of the front door 13. When the rotating sleeve 3 is in the second position, the pull rod 2 slides axially to make the spray gun 6 located in the drum 12.

[0040] That is to say, through the spray gun support assembly of the coating machine provided by the present application, when the drum 12 needs to be replaced, the support rod 5 is held to make the pull rod 2 move axially in the direction away from the front door 13, and then the support rod 5 is rotated clockwise to realize that the rotating sleeve 3 is in the first position. At this time, the support rod 5 and the spray gun 6 are away from the front door 13 and do not interfere with the opening or closing of the front door 13, thereby quickly replacing the drum 12; when spraying a fine mist of coating liquid on the plain tablets located in the drum 12, the support rod 5 is first rotated counterclockwise to realize that the rotating sleeve 3 is in the second position, and then the pull rod 2 is moved axially in the direction close to the front door 13 to realize that the spray gun 6 is located in the drum 12 to spray a fine mist of coating liquid. Therefore, the spray gun support assembly of the coating machine provided by the present application does not interfere when the drum 12 is replaced, and the pull rod does not need to be moved a long distance to affect its service life, and does not take up a large amount of installation space.

[0041] See also Figure 2 On the basis of the above embodiment, the limiting assembly 4 includes a bracket 41, which is fixed on the outer peripheral surface of the tail end of the pull rod 2, and the rotating sleeve 3 is inserted on the bracket 41. The bracket 41 is provided with a guide column 42 symmetrically arranged with respect to the rotating sleeve 3, and the guide column 42 is sleeved with a first elastic member 421 and a second elastic member 422;

[0044] That is to say, through the setting of the limit assembly 4 of the present application, the support rod 5 rotates clockwise, thereby driving the rotating sleeve 3 to rotate clockwise. Since the outer circumference of the rotating sleeve 3 is symmetrically provided with a rotating pressure block 43, a spring pressure block 44 is provided on the side of the rotating pressure block 43 away from the rotating sleeve 3. The spring pressure block 44 is sleeved on the guide column 42, and the spring pressure block 44 is located between the first elastic member 421 and the second elastic member 422, thereby driving the second elastic member 422 to be compressed downward. When the rotating pressure block 43 abuts against the first adjusting bolt 451, the rotating sleeve 3 is in the first position at this time, and since the gravity of the support rod 5 and the spray gun 6 is greater than the second The elastic force of the elastic member 422 causes the support rod 5 and the spray gun 6 to remain stationary in the first position; similarly, the support rod 5 rotates counterclockwise, thereby driving the rotating sleeve 3 to rotate counterclockwise, thereby driving the second elastic member 422 on the left to be compressed downward, and when the rotating pressure block 43 abuts against the second adjusting bolt 461, the rotating sleeve 3 is in the second position at this time, and because the gravity of the support rod 5 and the spray gun 6 is greater than the elastic force of the second elastic member 422, the support rod 5 and the spray gun 6 remain stationary in the second position. At this time, the straight line where the axial direction of the spray gun 6 is located is on the same axis as the center line of the drum 12, and thus when the spray gun 6 moves axially, it can be located inside the drum 12.

[0045] Specifically, the first elastic member 421 and the second elastic member 422 are both springs, and the first elastic member 421 and the second elastic member 422 can play a role in buffering the rotation of the rotating sleeve 3 .

[0046] Specifically, the rotating pressing block 43 is connected to the rotating sleeve 3 via the mounting plate 431 , and the spring pressing block 44 is connected to the rotating pressing block 43 via the clamping block 441 .
