[0028] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figure 1 The release agent spraying spray nozzle of this embodiment includes a device body 1, and also includes:

[0030] The adjusting mechanism 2 is arranged at the bottom of the device body 1 and is used to replace the caliber of the release agent nozzle.

[0031] In order to facilitate the spraying operation of the release agent, Figure 2 and Figure 3 As shown, the device body 1 includes a release agent delivery pipe 101, a fixed plate 102 is fixedly sleeved on the outer side of the bottom of the release agent delivery pipe 101, a first nozzle 103 is arranged at the bottom of the release agent delivery pipe 101, and a second nozzle 104 and a third nozzle 105 are respectively arranged on both sides of one end of the bottom of the fixed plate 102 away from the first nozzle 103. The release agent can be delivered to the first nozzle 103 through the release agent delivery pipe 101, and the release agent can be atomized and sprayed out through the first nozzle 103. At the same time, by replacing the first nozzle 103, the second nozzle 104 and the third nozzle 105, the efficiency of the release agent spraying can be adjusted.

[0032] In order to conveniently replace the first nozzle 103, the second nozzle 104 and the third nozzle 105, as shown in FIG. Figure 2 and Figure 4As shown, the adjustment mechanism 2 includes an adjustment disk 201, which is arranged at the bottom of the fixed plate 102, and a rotating shaft 202 is fixedly installed in the middle position of the inner wall of the adjustment disk 201. The top of the rotating shaft 202 passes through the inner wall of the fixed plate 102 and is provided with a servo motor 203. The top of the adjustment disk 201 is provided with evenly spaced annular placement grooves 204 for placing the first nozzle 103, the second nozzle 104 and the third nozzle 105. The outer side of the bottom of the rotating shaft 202 passes through the adjustment disk 201 and is fixedly sleeved with a rotating gear 205. The outer side of the rotating gear 205 is meshed with a movable tooth plate 206, and three cleaning plates 207 are fixedly installed on the outer side of the movable tooth plate 206. The servo motor 203 works to rotate the rotating shaft 202, thereby rotating the adjustment disk 201, so that the first nozzle 103, the second nozzle 104 and the third nozzle 105 can be replaced, and the spraying efficiency of the release agent can be adjusted.

[0033] In order to conveniently replace the first nozzle 103, the second nozzle 104 and the third nozzle 105, as shown in FIG. Figure 2-4 As shown, the fixed plate 102 and the adjustment disk 201 are both configured as a triangular structure with rounded corners. The cross-sectional area of ​​the fixed plate 102 is larger than the cross-sectional area of ​​the adjustment disk 201. The triangular structure allows the first nozzle 103, the second nozzle 104 and the third nozzle 105 to be easily replaced.

[0034] In order to ensure that the first nozzle 103, the second nozzle 104 and the third nozzle 105 can be replaced stably, Figure 2-3 As shown, filter plates 106 are fixedly installed at the bottom of the inner walls of the first nozzle 103, the second nozzle 104 and the third nozzle 105. The first nozzle 103, the second nozzle 104 and the third nozzle 105 are arranged in a ring with equal intervals. The inner diameter of the first nozzle 103 is smaller than the inner diameter of the second nozzle 104, and the inner diameter of the second nozzle 104 is smaller than the inner diameter of the third nozzle 105. By replacing nozzles with different inner diameters, the spraying efficiency of the release agent can be adjusted.

[0035] In order to provide power for nozzle replacement, such as Figure 2 As shown, the top middle position of the fixed plate 102 is fixedly connected to the servo motor 203, and the servo motor 203 is connected to the rotating shaft 202 through an output shaft transmission. The fixed plate 102 can install and fix the servo motor 203. The operation of the servo motor 203 causes the rotating shaft 202 to rotate, which can drive the adjustment disk 201 to rotate, and then the positions of the first nozzle 103, the second nozzle 104 and the third nozzle 105 can be replaced.

[0036] In order to conveniently clean the three filter plates 106, Figure 2-4As shown, the three cleaning plates 207 are arranged in a ring with equal intervals. In the initial state, the three cleaning plates 207 are respectively set at the gaps between the first nozzle 103, the second nozzle 104 and the third nozzle 105. The outer diameters of the first nozzle 103, the second nozzle 104 and the third nozzle 105 are the same. The top diameter of the first nozzle 103 is the same as the diameter of the release agent delivery pipe 101. The movable tooth plate 206 is rotatably installed on the bottom of the adjusting disk 201. The diameter of the movable tooth plate 206 is smaller than the gap size between the first nozzle 103, the second nozzle 104 and the third nozzle 105. The bottom of the filter plate 106 can be cleaned by the cleaning plate 207, which can ensure the smooth flow of the filter plate 106 and further ensure the smooth flow of the nozzles.

[0037] The specific implementation scenario is as follows: when spraying the release agent, the release agent can be transported to the inside of the first nozzle 103 through the release agent delivery pipe 101, and the release agent can be atomized and sprayed to the required position through the first nozzle 103. At the same time, the servo motor 203 works to rotate the rotating shaft 202, thereby causing the adjustment disk 201 to rotate counterclockwise, so that the first nozzle 103 can be detached from the bottom of the release agent delivery pipe 101, and then the second nozzle 104 can be moved to the bottom of the release agent delivery pipe 101. Similarly, the second nozzle 104 and the third nozzle 105 can be replaced, and nozzles with different inner diameters can be conveniently replaced, thereby conveniently improving the efficiency of spraying the release agent. Adjustments are made to make the spraying of the release agent more convenient. When the rotating shaft 202 rotates, the rotating gear 205 can be driven to rotate. Through the meshing action between the gear parts, the movable tooth plate 206 can be rotated at the bottom of the adjusting disk 201, and then the three cleaning plates 207 can be driven to rotate, so that the three cleaning plates 207 can clean the three filter plates 106, thereby ensuring the smooth flow of the three filter plates 106, thereby ensuring the stability of the spraying of the release agent, and then the spraying efficiency of the release agent can be conveniently adjusted according to different needs. This embodiment specifically solves the problem in the prior art that the inner diameter of the nozzle is fixed and the release agent spraying efficiency cannot be adjusted.

[0038] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
