[0026] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0027] like Figure 1 As shown, this utility model discloses a coating device, which includes: a transmission shaft 1, a drive mechanism, and an adjustment mechanism 4; a gear 2 is provided at one end of the transmission shaft 1, and a rack 3 is meshed with one side of the gear 2; the transmission shaft 1 is at least used to drive the gear 2 to rotate, and the gear 2 rotates and moves up and down along the rack 3 to drive the upper mold frame to move up and down.

[0028] like Figure 2 , Figure 3As shown, the adjusting mechanism 4 is disposed between the transmission shaft 1 and the drive mechanism, and is connected to both the transmission shaft 1 and the drive mechanism. The adjusting mechanism 4 is used at least to adjust the angle of the transmission shaft 1 and prevent the transmission shaft 1 from rotating. The adjusting mechanism 4 includes a first flange 5 and a second flange 6, with their end faces in contact. The first flange 5 is fixedly connected to the transmission shaft 1, and the second flange 6 is connected to the drive mechanism. The first flange 5 has multiple connecting holes, the center lines of which are perpendicular to the end face of the first flange 5. The second flange 6 has multiple oblong holes 7. Selectedly, a plurality of the oblong holes 7 are arranged in a circumferential array along the center line of the second flange 6. In this embodiment, six oblong holes 7 are arranged in a circumferential array on the second flange 6. The oblong holes 7 correspond to the positions of the connecting holes and communicate with the connecting holes. A locking element is provided in the oblong holes 7. The locking element is used to lock the first flange 5 and the second flange 6. The locking element can be a screw or other threaded locking structure. The connecting hole is provided with internal threads. In this embodiment, the locking element includes a screw. The screw passes through the oblong holes 7 and the connecting hole to fix the first flange 5 and the second flange 6.

[0029] The second flange 6 is provided with at least two adjusting units 8. Preferably, multiple adjusting units are arranged in a circumferential array along the end face of the second flange 6. This allows for more accurate adjustment of the angle of the drive shaft 1 and the angle of the adjusting gear 2, ensuring that the teeth of the gear 2 are synchronized with the teeth of the rack 3. Furthermore, it provides more stable fixation of the drive shaft 1, preventing it from rotating relative to the second flange 6 during rotation. In this embodiment, two adjusting units are provided, symmetrically arranged along the centerline of the drive shaft 1.

[0030] Specifically, the adjustment unit includes a waist-shaped hole 7 and adjustment holes disposed on the side of the waist-shaped hole 7. The adjustment holes include at least a first adjustment hole 9 and a second adjustment hole 10. The first adjustment hole 9 and the second adjustment hole 10 are respectively disposed on both sides of the waist-shaped hole 7, and both the first adjustment hole 9 and the second adjustment hole 10 communicate with the waist-shaped hole 7. A first adjustment member is disposed in the first adjustment hole 9, and a second adjustment member is disposed in the second adjustment hole 10. The position of the connecting member in the waist-shaped hole 7 is adjusted by the first adjustment member and the second adjustment member, thereby adjusting the angle of the drive shaft 1. The first adjustment member and the second adjustment member can be screws or other threaded structures. In this embodiment, both the first adjustment member and the second adjustment member are screws. The first adjustment member extends into the waist-shaped hole 7 through the first adjustment hole 9, and the second adjustment member extends into the waist-shaped hole 7 through the second adjustment hole 10. Both the first adjustment member and the second adjustment member are in contact with the outer surface of the locking member. The position of the locking member in the waist-shaped hole 7 is adjusted by adjusting the position of the first adjustment member and the second adjustment member extending into the waist-shaped hole 7, that is, the angle of the drive shaft 1 is adjusted.

[0031] This invention adjusts the angle of the transmission shaft 1, i.e. the angle of the gear 2, through the adjustment mechanism 4, so that the gear 2 and rack 3 can be synchronized, thus solving the technical problems of the gear 2 and rack 3 being out of sync and inconvenient to adjust. This invention has a simple structure and low cost.

[0032] In some implementations, the drive mechanism is at least used to drive the transmission shaft 1 to rotate. Specifically, the drive mechanism includes a motor 11 and a reducer 12, which are connected. The drive shaft of the reducer 12 is fixedly connected to the second flange 6. More specifically, the second flange 6 is connected to the drive shaft of the reducer 12 via a key and groove. The upper mold frame is fixedly mounted on the movable frame 13. As the movable frame 13 moves up and down, the lower mold frame is positioned below the upper mold frame. Covering is achieved through the mold closing mechanism of the upper and lower mold frames and the push block.

[0033] In some implementation cases, in order to make the upper mold frame move up and down symmetrically and evenly, there are two of each of the drive shaft 1, adjustment mechanism 4 and gear 2. The two drive shafts 1, two adjustment mechanisms 4 and two gears 2 are all symmetrically arranged along the drive mechanism.

[0034] In some implementations, a movable frame 13 is provided on one side of the drive shaft 1, the drive shaft 1 is rotatably connected to the movable frame 13, and the gear 2 rotates and meshes with the rack 3 to drive the movable frame 13 to move up and down.

[0035] Based on the above, such as Figure 4 As shown, a fixed frame 14 is provided on one side of the movable frame 13, and the rack 3 is fixedly mounted on the fixed frame 14. The gear 2 rotates to drive the movable frame 13 to move up and down relative to the fixed frame 14.

[0036] Based on the above, in order to make the moving frame 13 move up and down more smoothly, the fixed frame 14 and the moving frame 13 are slidably connected by the slide rail 15 and the slider 16. Specifically, the slider 16 is fixedly mounted on the moving frame 13, and the slide rail 15 is fixedly mounted on the fixed frame 14.

[0037] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
