DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Referring to Figures 1-5 , a coating liquid feeding device for a thin film coating device, including a mixing barrel 1, a plurality of support legs 2 are fixedly connected to the lower end of the mixing barrel 1, a setting is opened at the upper end of the mixing barrel 1, and a barrel cover 3 is arranged at the upper end of the mixing barrel 1. Two positioning grooves 4 are symmetrically opened at the upper end of the mixing barrel 1. Two positioning rods 5 are symmetrically and fixedly connected to the lower end of the barrel cover 3, and the vertical positions of the positioning grooves 4 and the positioning rods 5 correspond. When the barrel cover 3 is covered on the upper end of the mixing barrel 1, the positioning rods 5 are inserted into the positioning grooves 4, and the barrel cover 3 can be positioned and placed to prevent the barrel cover 3 from rotating on the upper end of the mixing barrel 1.

[0020] The mixing barrel 1 is designed separately, and the following feeding components and various structures for stirring are arranged on the barrel cover 3, which is convenient for separating the barrel cover 3 from the mixing barrel 1 and facilitating the cleaning of the inside of the mixing barrel 1 and other structures. A leakage hole is opened at the central position of the barrel cover 3. Two feeding components are symmetrically arranged on the upper end of the barrel cover 3 with respect to the leakage hole. The feeding component includes a feeding cylinder 11 fixedly arranged at the upper end of the barrel cover 3. The upper end of the feeding cylinder 11 is communicated with a feeding port 12. A connecting hose is communicated between the discharging port 9 and the feeding port 12 of the feeding cylinder 11. The feeding cylinder 11 is rotatably connected with a feeding shaft 13. The opposite ends of the two feeding shafts 13 both penetrate through the side wall of the feeding cylinder 11. A feeding auger 14 is arranged on the shaft body of the feeding shaft 13. The opposite ends of the two feeding cylinders 11 are opened and located at the leakage hole of the barrel cover 3. During feeding, the raw materials are sent out from the opening of the feeding cylinder 11 close to the leakage hole, and the raw materials fall into the mixing barrel 1 under their own gravity through the leakage hole.

[0021] Two cushion blocks 6 are symmetrically and fixedly connected to the front and rear of the upper end of the barrel cover 3. A support seat 7 is fixedly connected to the upper ends of the two cushion blocks 6. A batching component is arranged at the upper end of the support seat 7. The batching component includes two raw material barrels 8 symmetrically arranged at the upper end of the support seat 7. An observation window 81 is arranged on the barrel body of the raw material barrel 8, which is convenient for more intuitively observing the remaining situation of the raw materials in the raw material barrel 8. When the raw materials in the raw material barrel 8 are insufficient, the raw materials are replenished into the raw material barrel 8 in time.

[0022] A discharging port 9 is arranged at the lower end of the raw material barrel 8. A feeding port is arranged at the upper end of the raw material barrel 8, and an inclined surface is arranged on the inner bottom wall of the raw material barrel 8, which is convenient for the raw materials to slide along the inclined surface on the inner bottom wall of the raw material barrel 8 to the feeding port under their own gravity.

[0023] A partition plate 10 is slidably arranged at the blanking port 9 of the raw material barrel 8. The top view projection of the partition plate 10 covers the top view projection of the blanking port 9, and the lowest point of the inclined surface at the lower end of the raw material barrel 8 is connected to the blanking port 9, avoiding the existence of blanking dead angles in the raw material barrel 8 and ensuring that all the raw materials in the raw material barrel 8 can be discharged.

[0024] A stirring shaft 22 is arranged in the mixing barrel 1. A plurality of stirring rods 23 are fixedly distributed on the shaft body of the stirring shaft 22. A driving assembly is also arranged on the support seat 7. The driving assembly includes an installation groove 15 opened on the support seat 7. The inner top wall of the installation groove 15 is rotatably connected with a driving bevel gear 16. Two driven bevel gears 17 are symmetrically engaged with the lower end of the driving bevel gear 16. The two driven bevel gears 17 are fixedly connected to the inner side wall of the installation groove 15. A rotating rod 18 is coaxially rotatably connected to the opposite ends of the two driven bevel gears 17. A sprocket 19 is fixedly sleeved on the outer sides of the rotating rod 18 and the feeding shaft 13 on the same side. A chain 20 is connected between the two sprockets 19. A rotating motor 21 is fixedly installed at the upper end of the support seat 7. By arranging the two sprockets 19 in cooperation with the chain 20, the rotation of the rotating rod 18 can drive the feeding shaft 13 to rotate, and the rotation of the two feeding shafts 13 can respectively drive the feeding augers 14 thereon to perform feeding operations, saving equipment costs.

[0025] The output end of the rotating motor 21 is coaxially and fixedly connected to the upper end of the driving bevel gear 16. The lower end of the driving bevel gear 16 is coaxially and fixedly connected to the stirring shaft 22. And the lower end of the stirring shaft 22 passes through the leakage hole on the barrel cover 3. The diameter of the leakage hole on the barrel cover 3 is larger than the diameter of the stirring shaft 22. The leakage hole is not only penetrated by the stirring shaft 22, but also a feeding cylinder 11 is arranged above the leakage hole. When the feeding cylinder 11 conveys raw materials, the raw materials fall from the opening of the feeding cylinder 11 to the leakage hole and fall into the interior of the mixing barrel 1 after passing through the leakage hole.

[0026] The lower end of the mixing barrel 1 is connected and provided with a feeding pipe 24, and an electromagnetic valve is arranged on the feeding pipe 24. During feeding, the connection between the feeding pipe and the inside of the mixing barrel 1 is controlled by controlling the electromagnetic valve to control feeding.

[0027] The detailed working process of the present invention is as follows: During use, first, the raw materials of the coating liquid are separately placed into the raw material barrel 8. When the raw materials in the raw material barrel 8 are put into the mixing barrel 1, first, the partition plates 10 under the multiple raw material barrels 8 are pulled out, so that the raw material barrel 8 is communicated with the discharge port 9 of the raw material barrel 8 and the feed port 12 of the feeding cylinder 11. The rotating motor 21 drives the driving bevel gear 16, and the driving bevel gear 16 meshes with two driven bevel gears 17, driving the two driven bevel gears 17 to rotate. The rotation of the two driven bevel gears 17 drives the two rotating rods 18 to rotate. By arranging two sprockets 19 in cooperation with a chain 20, the rotation of the rotating rod 18 can drive the feeding shaft 13 to rotate. The rotation of the two feeding shafts 13 can respectively drive the feeding augers 14 thereon to perform the feeding operation. The raw materials fall through the opening above the leakage holes formed in the barrel cover 3 through the feeding cylinder 11 and enter the mixing barrel 1; Since the amount of raw materials conveyed by the feeding assembly in the same time is certain, according to the proportion of the raw materials, when enough of one kind of raw material is added, the partition plate 10 on the raw material barrel 8 is inserted to stop the addition of this raw material. For the raw materials in the other raw material barrel 8, the addition continues until the raw materials are added according to the total proportion of the raw materials, and then the partition plate 10 is inserted into the raw material barrel 8 to stop the addition of the raw materials; In addition to driving the two driven bevel gears 17 to rotate, the driving bevel gear 16 can also drive the stirring shaft 22 to rotate, driving the multiple stirring rods 23 on the shaft body of the stirring shaft 22 to rotate, so that the coating liquid in the mixing barrel 1 is stirred and mixed evenly and sufficiently; The mixing barrel 1 is designed separately, and the feeding assembly and various structures for stirring are arranged on the barrel cover 3, which is convenient for separating the barrel cover 3 from the mixing barrel 1 and facilitating the cleaning of the interior of the mixing barrel 1 and other structures.
