DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: an automatic feeding device, including a feeding box 1, the bottom of the feeding box 1 is arc-shaped, the bottom of the feeding box 1 is inclined, and the left side of the feeding box 1 is low and the right side is high.

[0021] Among them, the feeding box 1 is used to hold materials. The arc-shaped inclined bottom can make the materials move from a high place to a low place by gravity. During the feeding process, as the materials in the feeding box 1 decrease, the materials flow from the right side to the left side in the feeding box 1.

[0022] A discharge barrel 2 is provided at the bottom of the left side of the feeding box 1, a rotating shaft 3 is provided inside the discharge barrel 2, a spiral blade 4 is provided on the surface of the rotating shaft 3, the rotating shaft 3 is driven to rotate by a motor 5, the motor 5 is fixedly mounted on a lifting plate 6, and the lifting plate 6 is driven to rise and fall by a cylinder 7;

[0023] A driving shaft 14 is provided at the output end of the motor 5 , and the lower end of the driving shaft 14 is fixedly connected to the upper end of the rotating shaft 3 via a connecting block 15 .

[0024] Among them, the material inside the feeding box 1 is discharged and fed through the discharge barrel 2. During the feeding process, the motor 5 drives the drive shaft 14 to rotate, and the drive shaft 14 drives the spiral blade 4 to rotate through the rotating shaft 3, so that the material in the feeding box 1 is discharged through the discharge barrel 2, which can prevent the discharge barrel 2 from being blocked. The feeding speed of the material can also be controlled by the rotation speed of the spiral blade 4. When the motor 5 drives the spiral blade 4 to rotate faster, the discharge speed of the discharge barrel 2 is faster.

[0025] A blocking block 8 is provided at the lower end of the rotating shaft 3 . The blocking block 8 is in the shape of a truncated cone, and the diameter of the large circle at the bottom of the blocking block 8 is larger than the inner diameter of the discharge cylinder 2 .

[0026] A guide rail 9 is provided on the upper side of the inner wall of the feeding box 1, and a slider 10 matching the guide rail 9 is provided on the lifting plate 6, and the slider 10 is slidably connected to the guide rail 9;

[0027] Support frames 11 are provided on both sides of the feeding box 1 , and a support cross bar 12 is provided on the upper end of the support frame 11 . A fixing plate 13 is provided on the support cross bar 12 , and the cylinder 7 is fixedly mounted on the fixing plate 13 .

[0028] The material blocking block 8 is used to open or close the discharge barrel 2. When material replenishment is required, the cylinder 7 is started to make the lifting plate 6 move downward through the guide rail 9, and the material blocking block 8 is moved downward through the drive shaft 14 and the rotating shaft 3, so that the lower end of the discharge barrel 2 is opened, and then the spiral blade 4 is driven by the motor 5 to rotate so that the material is discharged from the discharge barrel 2 for replenishment. After the replenishment is completed, the material blocking block 8 is driven by the cylinder 7 to rise and close the discharge barrel 2. The inclined surface on the outside of the material blocking block 8 can prevent the material from being sandwiched between the material blocking block 8 and the discharge barrel 2.

[0029] A feed tray 16 is provided below the discharge barrel 2 . The feed tray 16 is inclined, and the outer side of the feed tray 16 is fixedly mounted on the support frame 11 via a connecting rod 17 .

[0030] The feed tray 16 is used to receive the material discharged from the discharge barrel 2 . The inclined feed tray 16 can allow the material to naturally slide down from the feed tray 16 by its own gravity.

[0031] The working principle and use process of this utility model:

[0032] During the feeding process, the motor 5 drives the drive shaft 14 to rotate. The drive shaft 14 drives the spiral blade 4 to rotate through the rotating shaft 3, so that the material in the feeding box 1 is discharged through the discharge tube 2 to feed the feeding tray, which can prevent the discharge tube 2 from being blocked. The feeding speed of the material can also be controlled by the rotation speed of the spiral blade 4. When the rotation speed of the spiral blade 4 driven by the motor 5 increases, the discharge speed of the discharge tube 2 becomes faster. The discharge tube 2 can be opened or closed by the baffle 8. When feeding is required, the air cylinder 7 is started, so that the lifting plate 6 moves downward through the guide rail 9. The baffle 8 moves downward through the drive shaft 14 and the rotating shaft 3, so that the lower end of the discharge tube 2 is opened. Then, the motor 5 drives the spiral blade 4 to rotate so that the material is discharged from the discharge tube 2 for feeding. After feeding is completed, the baffle 8 is driven by the air cylinder 7 to rise to close the discharge tube 2. The inclined surface outside the baffle 8 can prevent the material from being clamped between the baffle 8 and the discharge tube 2.
