The spray gun is mounted on a spray gun holder, which is mounted on the mounting shaft of the coating machine.

[0003] In actual use, the distance between the tablet bed and the spray gun varies depending on the loading amount. To ensure the best coating effect, the spray gun needs to be adjusted each time to ensure the best spray angle. However, the current spray guns cannot meet the needs of different angles.

[0004] To address this issue, we provide a spray gun adjustment device for a coating machine. Utility Model Content

[0005] The purpose of this invention is to provide a spray gun adjustment device for a coating machine. By rotating the handle, the meshing action between the worm and the worm wheel body causes the angle of the sliding block to change. The worm is connected to the rotating seat through a fixed collar, thereby indirectly achieving the purpose of adjusting the angle of the spray gun body, solving the problem of the existing angle being difficult to adjust.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-3 The present invention is a spray gun adjustment device for a coating machine, including a spray gun component 100, including a base 101, a spray gun body 102 fixed to the top of the base 101, and a connecting pipe 103 disposed on the spray gun body 102.

[0033] Angle adjustment component 200 includes a drive assembly 201 disposed at the bottom end of the base 101, a worm gear assembly 202 disposed on the bottom side of the drive assembly 201, and a fixing assembly 203 disposed on the worm gear assembly 202;

[0034] The interaction between the drive assembly 201 and the worm gear assembly 202 allows the overall angle of the drive assembly 201 to change, while the fixing assembly 203 can fix the position of the drive assembly 201.

[0035] Specifically, the drive assembly 201 includes a rotating seat 201a fixed to the bottom of the base 101, a fixing collar 201b fixed to the bottom of the rotating seat 201a, a worm 201c disposed inside the fixing collar 201b, an index 201d fixed to the side wall of the rotating seat 201a, and an index 201d fixed to the end of the worm 201c. The worm gear assembly 202 includes a bearing sleeve 202a disposed below the rotating seat 201a, guide grooves 202b opened on both sides of the top of the bearing sleeve 202a, a worm gear body 202c fixed to the outer wall of the bearing sleeve 202a, and a scale 202d fixed to both sides of the outer wall of the bearing sleeve 202a.

[0036] Furthermore, the fixing assembly 203 includes a fixing screw 203a fixed to the bottom of the rotating seat 201a, a fixing nut 203b sleeved on the outer wall of the fixing screw 203a, and a sliding block 203c sleeved on the outside of the fixing screw 203a corresponding to the fixing nut 203b. The worm 201c meshes with the worm wheel body 202c. The fixing screw 203a is located inside the guide groove 202b. The fixing nut 203b and the sliding block 203c are both located below the guide groove 202b. The fixing screw 203a and the sliding block 203c are threadedly connected.

[0037] The operation process of this embodiment is as follows: By rotating the handle 201e, the worm 201c is driven to rotate. Since the worm 201c and the worm wheel body 202c are meshed with each other, and the worm wheel body 202c is fixed to the outer wall of the bearing sleeve 202a, when the handle 201e is rotated, the worm 201c will be driven to rotate along the outer wall of the worm wheel body 202c, thereby changing the angle of the rotating seat 201a, indirectly changing the angle of the spray gun body 102, thereby achieving the optimal spray angle. In addition, by rotating the fixing nut 203b, the fixing nut 203b is moved. When the fixing nut 201e... When 3b moves upward, it will pressurize the sliding block 203c, increasing the friction between the sliding block 203c and the bearing sleeve 202a. The sliding block 203c is set on the outer wall of the fixing screw 203a. While the sliding block 203c is being squeezed, it also squeezes the rotating seat 201a, indirectly increasing the friction between the rotating seat 201a and the bearing sleeve 202a, thus fixing the rotating seat 201a. Furthermore, an index 201d is fixed on the side wall of the rotating seat 201a, which can point to the angle of the scale 202d, so as to adjust the angle of the spray gun body 102 more accurately.

[0038] Example 2

[0039] Please see Figure 1 Figure 4 and Figure 5 Based on Embodiment 1, it also includes a rotating component 300, which includes a mating component 301 at the bottom end of the worm gear assembly 202 and a pressing component 302 disposed on the mating component 301.

[0040] Specifically, the mating component 301 includes a fixing plate 301a disposed below the bearing sleeve 202a, an extension sleeve 301b fixed to the top of the fixing plate 301a, an adapter block 302c disposed inside the extension sleeve 301b, a connecting plate 301d fixed to the top of the extension sleeve 301b, and a locking block 301e fixed to the top of the connecting plate 301d.

[0041] Furthermore, the pressing assembly 302 includes a pressing sleeve 302a fixed to the bottom end of the bearing sleeve 202a, a pressure rod 302b fixed inside the pressing sleeve 302a, and an adapter block 302c fixed to the outer wall of the pressure rod 302b; wherein the outer wall of the pressure rod 302b is slidably connected to the inside of the extension sleeve 301b.

[0042] The operation process of this embodiment is as follows: First, press down on the pressing sleeve 302a. The pressing sleeve 302a moves downward, driving the adapter block 302c to move downward, so that the adapter block 302c disengages from the locking block 301e. At this time, the adapter block 302c and the locking block 301e will not engage, allowing the pressing sleeve 302a to rotate freely. In addition, during the downward movement of the pressing sleeve 302a, the pressure rod 302b will compress the spring 301c, causing the spring 301c to deform. When the pressing sleeve 302a is no longer under force, the spring 301c will reset, lifting the pressing sleeve 302a and driving the adapter block 302c to move upward back to its original position, so that the adapter block 302c and the locking block 301e re-engage, completing the fixation of the pressing sleeve 302a, and indirectly achieving the purpose of fixing the angle of the spray gun body 102.
