Description
Technical Field
[0001] This utility model relates to the field of automatic equipment technology, and in particular to an automatic extraction and dispensing device. Background Technology
[0002] Automatic extraction and dispensing equipment is designed to automate the extraction and precise dispensing of various materials (such as liquids and granular solids), improve production efficiency, reduce human error, and is widely used in production lines in the food, pharmaceutical, and chemical industries.
[0003] Currently, when dispensing granular solid materials, it is impossible to achieve precise quantitative dispensing. The feeding structure often uses spiral blades, but when the spiral blades stop, a small amount of material still falls from the bottom, resulting in an excessive loading capacity and failing to guarantee the accuracy of the loading amount each time. To address this, we have designed an automatic extraction and dispensing device. Utility Model Content
[0004] The purpose of this invention is to provide an automatic extraction and dispensing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An automatic extraction and dispensing device includes a base plate and an annular fixing plate. The annular fixing plate is fixedly sleeved on the outside of a storage tank. A conveying mechanism is provided on the top of the base plate. Two support plates are symmetrically provided on the front and rear sides of the conveying mechanism. The support plates are fixedly connected between the annular fixing plate and the base plate. A drive motor is provided at the center of the top of the storage tank. The output shaft of the drive motor passes through the inside of the storage tank and is connected to a rotating rod. The bottom of the storage tank is tapered downwards and a discharge pipe is connected to its bottom end. A connecting box is connected to the bottom of the discharge pipe. A weighing mechanism is provided at the bottom of the connecting box. The weighing mechanism includes a weighing box located above the conveying mechanism. The bottom of the weighing box has two rotating doors. The two doors are double doors. A discharge hole A is opened on the top of the weighing box. A discharge hole B corresponding to the discharge hole A is opened on the bottom of the connecting box. A material blocking mechanism is provided on the connecting box. The bottom end of the rotating rod extends into the lower part of the storage tank and is connected to a spiral blade. The bottom end of the spiral blade extends into the inside of the discharge pipe.
[0007] As a preferred embodiment of this utility model: the weighing mechanism further includes two mounting seats fixedly disposed at the bottom of the connecting box. The two mounting seats are symmetrically distributed on the left and right sides of the discharge hole B. Mounting blocks are respectively provided at the top of the left and right side surfaces of the weighing box. Mounting slots for mounting blocks to be embedded are respectively opened on the sides of the two mounting seats that are close to each other. A pressure sensor is embedded in the lower inner wall of the mounting slot.
[0008] As a further preferred embodiment of this utility model: the material blocking mechanism includes a movable baffle that is slidably disposed inside the connecting box. The top right side of the movable baffle has a through opening with the diameter of the through opening being equal to the diameter of the material discharge hole B. The right side surface of the connecting box is provided with a first electric push rod, the extended end of which penetrates into the interior of the connecting box and connects to the right side surface of the movable baffle.
[0009] As a further preferred embodiment of this utility model: two side plates are symmetrically provided on the lower part of the left and right sides of the weighing box. The bottom of the side plate is located below the bottom of the weighing box. The bottom end of the side plate near the box door is rotatably connected to a second electric push rod through a first hinge seat. The extended end of the second electric push rod is rotatably connected to the corresponding box door surface through the second hinge seat.
[0010] As a further preferred embodiment of this utility model: the top of the storage tank is provided with a cover plate that rotates via a hinge. The cover plate has a semi-circular structure, and a protruding plate is provided at the end of the cover plate away from the hinge. The top of the storage tank is provided with an abutment groove for the protruding plate to be inserted, and the top of the protruding plate is provided with a handle.
[0011] As a further preferred embodiment of this utility model: the diameter of the discharge hole B is smaller than the diameter of the discharge hole A, and the diameter of the discharge hole B is equal to the inner diameter of the discharge tube.
[0012] As a further preferred embodiment of this utility model: the top of the weighing box does not contact the bottom of the connecting box.
[0013] The beneficial effects of this utility model are as follows: When this device is in use, the drive motor is started, and the rotating rod drives the spiral blades to rotate, thereby conveying the material downward. The material passes through the feeding pipe and the inlet and smoothly enters the weighing box. As more and more material is added, the pressure sensor in the mounting slot detects that the pressure of the mounting block is also increasing. When the value reaches the preset value, the sensor transmits the signal to the controller. The controller controls the drive motor to stop, the first electric push rod to retract, and the two second electric push rods to retract as well. The first electric push rod can drive the moving baffle to move and close the inlet, instantly preventing the bottom of the spiral blades from continuing to fall, thus fully ensuring the accuracy of the weight of the material in the weighing box. Furthermore, the box door opens, and the material in the weighing box falls into the corresponding container, completing one filling cycle. This cycle is repeated to achieve automatic material extraction and accurate quantitative filling, making it highly practical. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0023] Please see Figure 1-6In this embodiment of the present invention, an automatic extraction and dispensing device includes a base plate 1 and an annular fixing plate 4. The annular fixing plate 4 is fixedly sleeved on the outside of a storage tank 8. A conveying mechanism 3 is provided on the top of the base plate 1. Two support plates 2 are symmetrically provided on the front and rear sides of the conveying mechanism 3. The support plates 2 are fixedly connected between the annular fixing plate 4 and the base plate 1. A drive motor 6 is provided at the center of the top of the storage tank 8. The output shaft of the drive motor 6 passes through the interior of the storage tank 8 and is connected to a rotating rod 23. The bottom of the storage tank 8 is tapered downwards, and a discharge pipe 12 is connected to its bottom end. A connecting box 13 is connected to the bottom of the discharge pipe 12, and a weighing mechanism is provided at the bottom of the connecting box 13. The weighing mechanism includes a weighing box 11 located above the conveying mechanism 3. The bottom of the weighing box 11 is provided with two rotating doors 17, which are double doors. The top of the weighing box 11 does not contact the bottom of the connecting box 13. The top of the weighing box 11 is provided with a discharge hole A, and the bottom of the connecting box 13 is provided with a discharge hole B corresponding to the discharge hole A. The diameter of the discharge hole B is smaller than that of the discharge hole A, and the diameter of the discharge hole B is equal to the inner diameter of the discharge pipe 12. The connecting box 13 is provided with a material blocking mechanism. The bottom end of the rotating rod 23 extends into the lower part of the storage tank 8 and is connected to a spiral blade 24. The bottom end of the spiral blade 24 extends into the interior of the discharge pipe 12.
[0024] The weighing mechanism also includes two mounting bases 15 fixedly installed at the bottom of the connecting box 13. The two mounting bases 15 are symmetrically distributed on the left and right sides of the discharge hole B. Mounting blocks 19 are respectively provided at the top of the left and right sides of the weighing box 11. Mounting slots 18 for mounting blocks 19 to be embedded are respectively opened on the sides of the two mounting bases 15 that are close to each other. Pressure sensors are embedded in the lower inner wall of the mounting slots 18.
[0025] The material blocking mechanism includes a movable baffle 25 slidably disposed inside the connecting box 13. A through-hole 26 is provided on the top right side of the movable baffle 25. The diameter of the through-hole 26 is equal to the diameter of the discharge hole B. A first electric push rod 14 is provided on the right side surface of the connecting box 13. The extended end of the first electric push rod 14 passes through the interior of the connecting box 13 and is connected to the right side surface of the movable baffle 25. The first electric push rod 14 can drive the movable baffle 25 to move to the left or right. When the movable baffle 25 moves to the leftmost position, the through-hole 26 is exactly between the discharge hole B and the bottom end of the discharge pipe 12, and the channel is open at this time. When the movable baffle 25 moves to the rightmost position, the left half of the movable baffle 25 blocks the bottom end of the discharge pipe 12, which can instantly prevent material from falling into the opening of the discharge pipe 12.
[0026] Two side plates 16 are symmetrically arranged on the lower part of the left and right sides of the weighing box 11. The bottom of the side plates 16 is located below the bottom of the weighing box 11. The bottom end of the side plate 16 near the box door 17 is rotatably connected to the second electric push rod 20 through the first hinge seat 21. The extended end of the second electric push rod 20 is rotatably connected to the surface of the corresponding box door 17 through the second hinge seat 22. In use, the two second electric push rods 20 are activated at the same time. The extension of the second electric push rod 20 can drive the box door 17 to close, thereby facilitating the loading and weighing of materials in the weighing box 11. The retraction of the second electric push rod 20 can drive the box door 17 to open, thereby facilitating the discharge and packaging of materials.
[0027] The top of the storage tank 8 is fitted with a cover plate 7 via a hinge. The cover plate 7 has a semi-circular structure, and a protruding plate 9 is provided at the end of the cover plate 7 away from the hinge. The top of the storage tank 8 has an abutment groove 10 for the protruding plate 9 to be inserted into, and a handle 5 is provided on the top of the protruding plate 9. The handle 5 facilitates opening the cover plate 7. In this device, the semi-circular structure of the cover plate 7, when opened, results in a larger feed inlet structure. Compared with the feed hopper or feed pipe in traditional devices, the feed inlet structure of this device is larger, making it easier to add materials. Furthermore, when the cover plate 7 is closed, it serves to prevent dust.
[0028] The device has a controller on the top of the base plate 1 or on the outer surface of the support plate 2. The controller is existing technology, and its internal structure, working principle and related electrical connections are not described in detail.
[0029] Specifically, in use, the loading boxes, containers, and barrels are placed sequentially on the conveying mechanism 3 for easy loading. During discharge, the drive motor 6 starts, rotating the spiral blades 24 via the rotating rod 23, thus conveying the material downwards. The material passes through the discharge pipe 12 and the opening 26, smoothly entering the weighing box 11. As more and more material accumulates, the pressure sensor in the mounting slot 18 detects that the pressure on the mounting block 19 is increasing. When the value reaches the preset value, the sensor transmits a signal to the controller. The controller stops the drive motor 6, retracts the first electric push rod 14, and retracts the two second electric push rods 20. The first electric push rod 14 can move the moving baffle 25 and close the opening 26, instantly preventing material from continuing to fall from the bottom of the spiral blades 24, thus ensuring the accuracy of the weight of the material in the weighing box 11. Furthermore, the box door 17 opens, and the material in the weighing box 11 falls into the corresponding container, completing one dispensing cycle. This cycle is repeated to achieve automatic material extraction and precise quantitative dispensing, making it highly practical.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
