Technical Field
[0001] The utility model relates to the field of milk tea powder packaging, in particular to a quantitative feeding device for milk tea powder. Background Art
[0002] During the packaging process of milk tea powder, it is necessary to control the amount of milk tea powder entering the packaging bag or packaging container. The existing packaging equipment lacks a quantitative packaging device. In order to control the amount of each packaging, the utility model provides a milk tea powder quantitative feeding device to solve the problems in the prior art. Utility Model Content
[0003] The utility model aims to provide a quantitative feeding device for milk tea powder to solve the problems in the prior art.
[0004] A quantitative feeding device for milk tea powder comprises a stirring bin and a quantitative bin, the stirring bin and the quantitative bin are integrally connected, a partition is arranged between the stirring bin and the quantitative bin, a stirring paddle is arranged in the stirring bin, a rotating shaft of the stirring paddle is rotatably connected to a bearing in the middle of the partition, a baffle is arranged on the stirring bin, and the rotating shaft is connected to a motor on the baffle.
[0005] The stirring paddle mixes the milk tea powder evenly to prevent the milk tea powder from clumping. Before the milk tea powder enters the quantitative bin, the partition isolates the milk tea powder in the stirring bin. When the stirring paddle is stirring the milk tea powder, the baffle closes the stirring bin to prevent the milk tea powder dust from escaping.
[0006] The partition is provided with a feeding port, and the milk tea powder raw material enters the mixing bin through the feeding port.
[0007] The stirring paddle is provided with a retaining ring, and the retaining ring is provided with a notch corresponding to the feeding port.
[0008] The retaining ring rotates with the stirring paddle. When the notch on the retaining ring corresponds to the discharge port, the motor stops and the milk tea powder enters the quantitative bin through the discharge port.
[0009] A feeding pipe is arranged at the bottom of the quantitative bin, the feeding port is staggered with the feeding pipe in the vertical direction, and the feeding pipe is movably connected with the quantitative bin.
[0010] A weight sensor is provided on one side of the discharge pipe of the quantitative bin, and the weight sensor is electrically connected to the power supply. When the weight of the milk tea powder fed back by the weight sensor at the bottom of the quantitative bin reaches the packaging requirement, the milk tea powder is filled into the packaging bag or the packaging container. The quantitative bin is fixedly connected with a bracket in the circumferential direction.
[0011] A cylinder is provided on the other side of the discharge pipe of the quantitative bin, the base end of the cylinder is fixedly connected to the quantitative bin, and the telescopic end of the cylinder is fixedly connected to the discharge pipe through a connecting ring. When the cylinder is started, it extends downward and pushes the discharge pipe through the connecting ring to package the milk tea powder.
[0012] The retaining ring is annular and fixedly connected to the stirring paddle. The notch is located between any two paddles of the stirring paddle. The retaining ring rotates with the stirring paddle. The milk tea powder is stirred evenly by the stirring paddle to prevent the milk tea powder from clumping. When the notch on the retaining ring corresponds to the discharge port, the milk tea powder enters the quantitative bin from the discharge port. When the milk tea powder in the quantitative bin reaches the quantitative requirement, the weight sensor at the bottom of the quantitative bin feeds back to the control system, and the stirring paddle rotates. After the stirring paddle rotates, it drives the retaining ring to rotate. The retaining ring blocks the discharge port to complete the quantitative discharge of the milk tea powder.
[0013] A limiting tube is arranged at the bottom of the quantitative bin, and the limiting tube is axially movably connected to the discharge tube. When one end of the discharge tube in the quantitative bin moves into the limiting tube, milk tea powder is discharged from the quantitative bin; when the quantitative bin is fed through the feed port, the milk tea powder is accumulated between the outer wall of the discharge tube and the inner wall of the quantitative bin, and the quality is fed back through the weight sensor at the outer bottom of the quantitative bin.
[0014] The baffle is provided with a feed inlet, and the milk tea powder raw material enters the stirring chamber from the feed inlet.
[0015] The quantitative bin is in the shape of an inverted frustum, and the feed discharge pipe is movably connected to the bottom plane of the inverted frustum.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. The utility model is simple and reasonable in structure. After the milk tea powder enters the stirring bin through the feeding port, the stirring paddle rotates to prevent the milk tea powder from agglomerating. At the same time, the stirring paddle pushes the milk tea powder. When the notch of the retaining ring on the stirring paddle corresponds to the feeding port on the baffle, the milk tea powder enters the quantitative bin and then controls the amount of packaging through the weight sensor at the bottom of the quantitative bin.
[0018] 2. A feed pipe is arranged under the quantitative bin and is controlled by a cylinder. Meanwhile, a limit tube is arranged at the bottom of the quantitative bin. When the milk tea powder in the quantitative bin meets the packing requirements, the feed pipe is pushed by the cylinder until the feed pipe moves into the limit tube at one end of the quantitative bin, and the milk tea powder is discharged from the quantitative bin. When the milk tea powder enters the quantitative bin through the feed port, the milk tea powder accumulates between the outer wall of the feed pipe and the inner wall of the quantitative bin, and the weight of the milk tea powder in the quantitative bin is fed back through the weight sensor.

DETAILED DESCRIPTION
[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below.
[0026] Example 1
[0027] like Figure 1 As shown, a quantitative feeding device for milk tea powder includes a stirring bin 1 and a quantitative bin 4, the stirring bin 1 and the quantitative bin 4 are integrally connected, a partition 14 is arranged between the stirring bin 1 and the quantitative bin 4, a stirring paddle 11 is arranged in the stirring bin 1, a rotating shaft 10 of the stirring paddle 11 is rotatably connected to a bearing in the middle of the partition 14, a baffle 15 is arranged on the stirring bin 1, and the rotating shaft 10 is connected to a motor 3 on the baffle 15.
[0028] like Figure 2 As shown, after the milk tea powder enters the stirring chamber 1, the stirring paddle 11 rotates driven by the motor 3.
[0029] like Figure 3 As shown, the milk tea powder will generate dust when stirred by the stirring paddle 11. After the dust escapes from the stirring chamber 1, the quality is reduced and the working environment is affected. The baffle 15 is used to prevent the dust from escaping.
[0030] The partition 14 is provided with a feeding port 13. Before the milk tea powder is fed, the partition 14 separates the milk tea powder in the mixing bin.
[0031] The stirring paddle 11 is provided with a retaining ring 12 , and a notch corresponding to the feeding port 13 is provided on the retaining ring 12 . When the notch on the retaining ring 12 corresponds to the feeding port 13 , the milk tea powder enters the quantitative bin 4 from the stirring bin through the feeding port 13 .
[0032] A feeding pipe 6 is provided at the bottom of the quantitative bin 4, and the feeding port 13 is staggered from the feeding pipe 6 in the vertical direction. The milk tea powder enters the quantitative bin 4 from the mixing bin first, and does not directly enter the feeding pipe 6. The feeding pipe 6 is movably connected to the quantitative bin 4;
[0033] A weight sensor 5 is provided on one side of the discharge pipe 6 of the quantitative bin 4, and the weight sensor 5 is electrically connected to the power supply. The weight sensor uses an SLP33xD weighing sensor; when the milk tea powder in the quantitative bin 4 fed back by the weight sensor 5 reaches the packing amount, the control system drives the motor 3, and the driving motor 3 drives the stirring paddle 11 to rotate, and the retaining ring 12 rotates with the stirring paddle 11, and the notch of the retaining ring 12 covers the discharge port 13, closing the feeding channel of the quantitative bin 4;
[0034] The control system is based on single-chip microcomputer control, and the single-chip microcomputer model is STM8S003F3. The single-chip microcomputer is electrically connected to the motor 3 and the cylinder 7, and the quantitative bin 4 is fixedly connected with a bracket 9 in the circumferential direction.
[0035] like Figure 4 As shown, a cylinder 7 is provided on the other side of the discharge pipe 6 of the quantitative bin 4, the base end of the cylinder 7 is fixedly connected to the quantitative bin 4, and the telescopic end of the cylinder 7 is fixedly connected to the discharge pipe 6 through a connecting ring 8. When the milk tea powder in the quantitative bin 4 reaches the packing amount, the powder is discharged through the discharge pipe 6 for packing, and the cylinder 7 is controlled by the control system to extend downward, and the milk tea powder enters the packing bag or other packing containers through the discharge pipe 6.
[0036] The retaining ring 12 is annular and is fixedly connected to the stirring paddle 11. When the cylinder 7 extends downward, the retaining ring 12 moves to the bottom of the quantitative bin 4, and the milk tea powder in the quantitative bin 4 is easy to enter the discharge pipe 6. When the weight sensor 5 feedbacks that the milk tea powder in the quantitative bin 4 has been packed, it feedbacks to the control system, and the control system drives the cylinder 7 to retract upward, and the discharge pipe 6 contracts. The contracted part of the discharge pipe 6 closes the quantitative bin 4. When the milk tea powder enters the quantitative bin 4 again, the milk tea powder accumulates between the wall of the quantitative bin 4 and the discharge pipe 6, and the gap is located between any two paddles of the stirring paddle 11.
[0037] like Figure 5 As shown,
[0038] A limiting tube 16 is provided at the bottom of the quantitative bin 4 , and the limiting tube 16 is axially movably connected to the feeding tube 6 .
[0039] When the milk tea powder enters the feeding tube 6 from the quantitative bin 4 , one end of the feeding tube 6 in the quantitative bin 4 moves axially in the limiting tube 16 .
[0040] A feed inlet 2 is provided on the baffle 15 , and the milk tea powder enters the mixing chamber 1 through the feed inlet 2 .
[0041] The stirring blade 11 includes a blade, and an angle is formed between the blade and the partition 14.
[0042] The partition 14 is parallel to the horizontal plane, and the angle of the paddle blades makes the rotation speed of the milk tea powder moderate. The milk tea powder is stirred under the drive of the paddle blades to avoid agglomeration and push the milk tea powder into the discharge port 13.
[0043] The quantitative bin 4 is in the shape of an inverted frustum, and the feed pipe 6 is movably connected to the bottom plane of the inverted frustum.
[0044] Example 2
[0045] In this embodiment, the single chip microcomputer in Example 1 is replaced with a PLC control system based on S7-200. The PLC operation is simple and easy to maintain. The speed of the motor 3 can be controlled by the PLC setting. When the motor 3 is initially driven, the motor 3 can be given a low speed by the PLC. When the retaining ring 12 and the discharge port 13 correspond, when the PLC disconnects the power supply of the motor 3, the low speed of the motor 3 can prevent the rotational inertia of the stirring paddle 11 from causing the gap of the retaining ring 12 to exceed the discharge port, and the correspondence between the retaining ring 12 and the discharge port 13 can be controlled more accurately, so that the milk tea powder enters the quantitative bin 4.
[0046] Example 3
[0047] In this embodiment, the air cylinder 7 in Embodiment 1 is replaced by a hydraulic cylinder. The output speed of the hydraulic cylinder is relatively slow. When the hydraulic cylinder drives the discharge pipe 6 to move, the discharge pipe 6 can be extended and retracted at a uniform speed, thereby improving the stability of the discharge process.
[0048] The working principle of the utility model is:
[0049] First, the milk tea powder enters the stirring bin 1 through the feed port 2, the partition 14 separates the stirring bin 1 and the quantitative bin 4, the motor 3 is started through the control system, the motor 3 drives the stirring paddle 11 to rotate through the rotating shaft 10, the stirring paddle 11 stirs the milk tea powder to prevent the milk tea powder from agglomerating, the retaining ring 12 on the stirring paddle 11 blocks the discharge port 13, the stirring paddle 11 drives the retaining ring 12 to rotate, when the notch on the retaining ring 12 corresponds to the discharge port 13, the milk tea powder enters the quantitative bin 4 through the discharge port 13, and the milk tea powder accumulates between the outer wall of the discharge pipe 6 and the inner wall of the quantitative bin 4 During the process, the weight sensor 5 at the bottom of the quantitative bin 4 feeds back the weight of the milk tea powder in the current quantitative bin 4 to the control system. When the weight of the milk tea powder in the quantitative bin 4 reaches the packaging requirement, it feeds back to the control system, and the control system starts the motor 3. The stirring paddle 11 drives the retaining ring 12 to rotate, closes the discharge port 13, and then controls the extension of the cylinder 7 through the control system. The cylinder 7 drives the discharge pipe 6 to extend through the connecting ring 8. After one end of the discharge pipe 6 in the quantitative bin moves into the limiting pipe 16, the milk tea powder is discharged from the discharge pipe 6 to complete the quantitative discharge of the milk tea powder.
