Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to an automatic feeding device for a vacuum mixer. Background Technology

[0002] In many industrial production fields, such as chemical, food, pharmaceutical, and new materials, the mixing process is a key step to ensure uniform mixing and full reaction of materials. As an important mixing equipment, the vacuum mixer has been widely used due to its unique advantage of being able to perform mixing operations in a vacuum environment. Mixing in a vacuum environment can effectively prevent adverse reactions between materials and oxygen, moisture and other components in the air, prevent materials from oxidizing, absorbing moisture and deteriorating, and at the same time reduce the bubbles generated during the mixing process, thereby improving the quality and performance of the product. However, in the actual use of vacuum mixers, the feeding process has always been a crucial factor affecting production efficiency and product quality. Traditional vacuum mixer feeding methods mostly rely on manual operation. Operators need to manually add materials to the mixer based on production experience and process requirements. Manual feeding makes it difficult to accurately control the amount of material added, and the amount of material added may vary greatly between different batches. For some production processes with strict requirements on raw material ratios, such feeding errors will directly affect the quality stability of the product, leading to large fluctuations in product performance indicators and even the emergence of unqualified products.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example 1 Reference Figure 1 , Figure 2 and Figure 4This is the first embodiment of the present invention. This embodiment provides an automatic feeding device for a vacuum mixer, including a frame 1, a feeding cylinder 2 slidably connected to the top of the frame 1, a discharging cylinder 3 disposed inside the frame 1, a control component 4 for controlling the quantitative feeding of the feeding cylinder 2 disposed inside the frame 1, and an anti-stacking component 5 for preventing the material from accumulating in the discharging cylinder 3 disposed inside the frame 1. The control component 4 includes grooves 401 symmetrically opened inside the frame 1, a connecting plate 402 slidably connected to the inner side of the grooves 401, a metering cylinder 403 fixedly connected to the bottom of the connecting plate 402, a limiting plate 404 fixedly connected to the outer wall of the metering cylinder 403, an opening and closing plate 405 rotatably connected inside the limiting plate 404 via a shaft pin, the top of the opening and closing plate 405 abutting against the bottom of the metering cylinder 403, and a limiting strip 406 fixedly connected inside the frame 1, the bottom of the opening and closing plate 405 abutting against the inner side of the limiting strip 406.

[0019] Specifically, an electric push rod 407 is fixedly connected inside the frame 1, and a fixed plate 408 is fixedly connected to the side of the limiting plate 404 near the electric push rod 407. The output end of the electric push rod 407 is fixedly connected to the outer wall of the fixed plate 408.

[0020] Furthermore, when feeding material into the feed cylinder 2, the material is poured into the feed cylinder 2. The material in the feed cylinder 2 falls freely under the action of gravity and enters the metering cylinder 403 below. When the metering cylinder 403 is filled with material, the electric push rod 407 is started to extend. Its output end pushes the fixed plate 408, which in turn drives the limiting plate 404 and the metering cylinder 403 to slide along the groove 401 away from the electric push rod 407. The metering cylinder 403 gradually moves to the top of the discharge cylinder 3 to prepare for the material to fall. When the metering cylinder 403 moves accurately to the designated position above the discharge cylinder 3, the opening and closing plate 405 is no longer limited by the limiting strip 406. Under the action of the material's gravity, the opening and closing plate 405 rotates around the shaft pin and opens downwards. The bottom of the metering cylinder 403 is open, and the material stored inside falls quickly and accurately into the discharge cylinder 3 below under the action of gravity. Then, the material in the discharge cylinder 3 enters the vacuum mixer for stirring.

[0021] Example 2 Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The anti-stacking component 5 includes a fixed seat 501 fixedly connected to the inner side of the frame 1. The top of the fixed seat 501 is rotatably connected to a rotating rod 502 through a bearing. The top of the rotating rod 502 is fixedly connected to the bottom of the feeding cylinder 3. A sliding groove 503 is provided inside the frame 1. A feeding pipe 504 is fixedly connected to the outer wall of the feeding cylinder 3. The output end of the feeding pipe 504 extends to the outside of the frame 1 and is slidably connected to the inner side of the sliding groove 503.

[0022] Specifically, a fixing strip 505 is fixedly connected to the outer wall of the fixing base 501. A drive rod 506 is rotatably connected inside the fixing strip 505 via a bearing. A rotating disk 507 is fixedly connected to one end of the drive rod 506 near the feed cylinder 3. A swing rod 508 is fixedly connected inside the rotating rod 502. A swing seat 509 is rotatably connected to the outer wall of the swing rod 508 via a bearing. A connecting rod 510 is fixedly connected to one side of the swing seat 509 near the rotating disk 507. The end of the connecting rod 510 away from the swing seat 509 is rotatably connected to the inside of the rotating disk 507 via a bearing. The end of the connecting rod 510 near the rotating disk 507 is spherically shaped. A motor 511 is fixedly connected to the top of the fixing strip 505. The end of the drive rod 506 away from the swing seat 509 is fixedly connected to the output end of the motor 511. The lower ends of both the feed cylinder 2 and the feed cylinder 3 are inverted conical.

[0023] Furthermore, to prevent material accumulation in the feeding cylinder 3, the motor 511 is started, driving the drive rod 506 to rotate around the bearing inside the fixed bar 505. The rotation of the drive rod 506 synchronously drives the rotating disk 507 to rotate as well. During the rotation of the rotating disk 507, the connecting rod 510, which is rotatably connected to the rotating disk 507 via the bearing, is subjected to the force applied by the rotating disk 507. When the connecting rod 510 moves under the drive of the rotating disk 507, it pulls the swing seat 509, thereby causing the swing rod 508 to swing. The swing of the swing rod 508 is transmitted to the rotating rod 502. 502 is connected to the top of the fixed seat 501 via a bearing. The rotating rod 502 will reciprocate around its own axis under the support of the bearing. The reciprocating rotation of the rotating rod 502 will cause the feeding cylinder 3 fixedly connected to its top to swing together. During the swing, the position of the feeding cylinder 3 changes continuously, and the feeding pipe 504 also slides in the sliding groove 503, thereby changing the falling trajectory of the material. This prevents the material from falling in a fixed position. Instead, it forms a dynamic and dispersed distribution in the mixing area with the swing of the feeding cylinder 3, effectively avoiding the accumulation of material in a local position in the mixing area.

[0024] Working principle: When feeding material into the feed cylinder 2, the material is poured into the feed cylinder 2. The material in the feed cylinder 2 falls freely under the action of gravity and enters the metering cylinder 403 below. When the metering cylinder 403 is full, the electric push rod 407 is activated to extend. Its output end pushes the fixed plate 408, which in turn drives the limiting plate 404 and the metering cylinder 403 to slide together along the groove 401 away from the electric push rod 407. The metering cylinder 403 gradually moves to the feeding cylinder. Directly above 3, it prepares for the material to fall. When the metering cylinder 403 moves accurately to the designated position directly above the feeding cylinder 3, the opening and closing plate 405 is no longer limited by the limiting strip 406. Under the action of the material's gravity, the opening and closing plate 405 rotates around the shaft pin and opens downwards. The bottom of the metering cylinder 403 is open, and the material stored inside falls quickly and accurately into the feeding cylinder 3 below under the action of gravity. Then, the material in the feeding cylinder 3 enters the vacuum mixer for mixing. To prevent material accumulation in the feeding cylinder 3, the motor 511 is started, driving the drive rod 506 to rotate around the bearing inside the fixed bar 505. The rotation of the drive rod 506 synchronously drives the rotating disk 507 to rotate as well. During the rotation of the rotating disk 507, the connecting rod 510, which is rotatably connected to the rotating disk 507 via the bearing, is subjected to a force applied by the rotating disk 507. When the connecting rod 510 moves under the drive of the rotating disk 507, it pulls the swing seat 509, causing the swing rod 508 to swing. The swing of the swing rod 508 is transmitted to the rotating rod 502. Since the rotating rod 502... 2. The rotating rod 502 is connected to the top of the fixed seat 501 through the bearing. Under the support of the bearing, the rotating rod 502 will reciprocate around its own axis. The reciprocating rotation of the rotating rod 502 will drive the feeding cylinder 3 fixedly connected to its top to swing together. During the swing, the position of the feeding cylinder 3 changes continuously, and the feeding pipe 504 also slides in the sliding groove 503, thereby changing the falling trajectory of the material. This prevents the material from falling in a fixed position. Instead, it forms a dynamic and dispersed distribution in the mixing area with the swing of the feeding cylinder 3, effectively avoiding the accumulation of material in a local position in the mixing area.
