[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a spraying box 1, a conveying component 2, a drying component 3 and an electrical control box 4. The conveying component 2 is installed inside the spraying box 1, the drying component 3 is installed on the top wall inside the spraying box 1, and the electrical control box 4 is fixedly installed on the front side wall of the spraying box 1 by bolts. Dustproof curtains 15 are provided at the material inlets on both the left and right sides of the spraying box 1. Through the dustproof effect of the dustproof curtains 15, dust and impurities in the outside air can be prevented from entering the spraying box 1 and affecting the spraying effect of the silicone pad.

[0025] It also includes:

[0026] The fixed frame 5 is fixedly installed on the upper right side of the spray box 1 by bolts. A first motor 6, which is electrically connected to the electrical control box 4, is fixedly installed inside the fixed frame 5 by bolts. A rotating disk 7 is fixedly sleeved on the output shaft of the first motor 6. A connecting rod 8 is rotatably connected to the lower part of the rotating disk 7.

[0027] The first slider 9 is slidably disposed in the first groove opened on the top wall of the spray box 1. The upper part of the first slider 9 is rotatably connected to one end of the connecting rod 8 through a shaft and bearing. The first slider 9 is provided with a spraying component 10, which is located in the spray box 1 at the right side of the drying component 3. The left and right sides of the drying component 3 in the spray box 1 are fixed with partitions 16 by bolts. The partitions 16 can reduce heat leakage and thus improve the drying effect of the drying component 3 on the coating on the silicone pad.

[0028] Flattening mechanism 11, which is located inside the spray box 1 on the left side of the drying assembly 3;

[0029] The flattening mechanism 11 includes:

[0030] The second motor 11-1 is fixedly mounted on the upper part of the spray box 1 by bolts. The second motor 11-1 is electrically connected to the electrical control box 4. The output shaft of the second motor 11-1 is fixedly mounted with a first threaded rod 11-2, which is located inside the spray box 1. A connecting cylinder 11-3 is rotatably mounted on the first threaded rod 11-2 through a thread.

[0031] The connecting frame 11-4 is fixedly installed at the lower end of the connecting cylinder 11-3 by bolts. Two rotating shafts 11-5 are rotatably installed inside the connecting frame 11-4 through bearings. The front ends of the two rotating shafts 11-5 pass through the front side wall of the connecting frame 11-4 and are connected by belt and pulley. Cooling roller 11-6 and heating roller 11-7 are respectively fixedly sleeved on the left and right rotating shafts 11-5.

[0032] Motor 11-8 is fixedly mounted on the rear side wall of connecting frame 11-4 by bolts. Motor 11-8 is electrically connected to electrical control box 4. The output shaft of motor 11-8 is connected to the left rotating shaft 11-5. Telescopic rods 11-9 are fixedly mounted on the front and rear sides of the upper part of connecting frame 11-4 by bolts. One end of telescopic rod 11-9 is connected to the inner top wall of spray box 1.

[0033] Example 2:

[0034] See Figure 2 As shown, based on Embodiment 1, a further improvement is made. A second slider 12 is slidably disposed in the second groove on the rotating disk 7. The second slider 12 is rotatably connected to the other end of the connecting rod 8 via a shaft and bearing. A second threaded rod 13 is rotatably connected to the second groove via a bearing. The second slider 12 is rotatably sleeved on the second threaded rod 13 via a thread. A fourth motor 14, which is electrically connected to the electrical control box 4, is fixedly disposed on the annular side wall of the rotating disk 7 via bolts. The output shaft of the fourth motor 14 is connected to the second threaded rod 13. The second slider 12 can slide in the second groove by rotating the second threaded rod 13. The distance between the other end of the connecting rod 8 and the center of the rotating disk 7 can be adjusted, thereby adjusting the reciprocating range of the first slider 9 driven by the connecting rod 8 during the rotation of the rotating disk 7. This allows the reciprocating spraying range of the spraying assembly 10 to be adjusted according to the specifications of the silicone pad.

[0035] When using this utility model, the conveying component 2 conveys the silicone pad to be sprayed into the spraying box 1. At the same time, the first motor 6 is started, which drives the rotating disk 7 to rotate. The rotating disk 7 drives the first slider 9 to move back and forth in the first groove through the connecting rod 8. The first slider 9 drives the spraying component 10 to move back and forth, so that the spraying component 10 can spray the upper part of the silicone pad evenly. Then, the conveying component 2 continues to convey the silicone pad after spraying to the left, so that the drying component 3 can dry the coating on the silicone pad at high temperature. Then, the silicone pad moves to the left with the conveying component 2 to the bottom of the heating roller 11-7. At this time, the third motor 11-8 drives the left rotating shaft 11-5 to rotate. With the transmission of the pulley and belt, the two rotating shafts 11-5 can synchronously drive the cooling roller 11-6 and the heating roller 11-7 to rotate, so that the heating roller 11-7 heats and presses the silicone pad. Then, the cooling roller 11-6 cools the silicone pad simultaneously while pressing it flat.

[0036] When it is necessary to adjust the flattening height of the cooling roller 11-6 and the heating roller 11-7 according to the thickness specification of the silicone pad, the first threaded rod 11-2 can be rotated by the second motor 11-1, and the height of the connecting frame 11-4 can be adjusted by using the telescopic rod 11-9 to guide the telescopic movement of the connecting frame 11-4. This allows the height of the cooling roller 11-6 and the heating roller 11-7 to be adjusted. When it is necessary to adjust the reciprocating spraying range of the spraying assembly 10 according to the width specification of the silicone pad, the second threaded rod 13 can be rotated by the fourth motor 14, allowing the second slider 12 to slide in the second groove. This changes the distance between the other end of the connecting rod 8 and the center of the rotating disk 7, thus adjusting the reciprocating movement range of the first slider 9 driven by the connecting rod 8 during the rotation of the rotating disk 7.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] 1. With the cooperation of the flattening mechanism 11, the rubber pad after spraying and drying can be flattened to avoid the rubber pad from deforming due to heat during the drying process of the coating and affecting the flatness. It is also convenient to adjust according to the thickness specifications of the silicone pad.

[0039] 2. Through the cooperation of motor 6, rotating disk 7, connecting rod 8, slider 9, slider 12, threaded rod 13, and motor 14, the spraying assembly 10 can be driven to move back and forth to achieve uniform spraying of the silicone pad. It is also easy to adapt and adjust according to the width of the silicone pad, thus expanding the scope of application.

[0040] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
