Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a powder packing device. Background Art

[0002] The packaging technology of powder is widely applied, especially in the processes of making koji and liquor. After the daqu is fermented, disassembled and stored, the koji blocks need to be ground, metered, packed and transported to the liquor production for use. At present, there are mainly two relatively mature metering, packing and transporting methods, namely manual sack packing and koji powder tanker transporting.

[0003] In the way of manual sack packing, putting koji, metering, loading, tying the bag and transporting are all completed manually, with high labor intensity and low work efficiency. In the way of koji powder tanker transporting, first, the koji powder in the tanker is transported to the loading position by a long conveying pipeline, and then the packing bag is used for loading. Since the tanker and the conveying pipeline are in a closed space, it is inconvenient to clean, and it is easy to cause koji powder to remain in the tanker or the conveying pipeline. The remaining koji powder may affect the quality of daqu, and the investment and operation and maintenance costs of this method are relatively high.

[0004] Especially during the loading process, a large amount of dust will be generated when the koji powder falls into the packing bag, and the dust is easy to leak out from the bag mouth of the packing bag, which will not only cause waste of koji powder, but also pollute the working environment and affect the health of the staff. Content of the Utility Model

[0005] The purpose of the utility model is to provide a powder packing device to improve the problems of easy generation of dust and dust leakage during the loading process.

[0013] In some embodiments, the powder packing device further includes a control system. The control system includes a controller and a metering sensor. The metering sensor is used to detect the loading amount information of the packaging bag and feedback it to the controller; the controller controls the buffer valve of the buffer bin, the flow control component of the flow control mechanism, the clamping mechanism, and the conveying mechanism to act together based on the loading amount information.

[0014] In some embodiments, the conveying component includes a conveying bracket, conveying rollers, and a conveying motor. The conveying rollers are arranged at intervals along the radial direction on the conveying bracket, and the conveying motor drives the conveying rollers to rotate;

[0020] In some embodiments, the flow control bin is flat, and the flow control outlet and the flow control inlet are arranged offset in the vertical direction.

[0021] In some embodiments, the clamping mechanism includes a clamping and releasing airbag. The clamping and releasing airbag expands outward during inflation to clamp the bag mouth; the clamping and releasing airbag contracts inward during deflation to release the bag mouth.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] As Figure 1 and Figure 2 shown, this embodiment provides a powder packing device, which includes a buffer bin 10, a flow control mechanism, a loading pipeline 30, a clamping mechanism 40, a conveying mechanism, and a control system.

[0031] The buffer bin 10 of this embodiment is preferably in the shape of a hollow square cylinder. The top of the buffer bin 10 has a buffer inlet, and the bottom of the buffer bin 10 has a buffer outlet. A buffer valve is provided at the buffer inlet of the buffer bin 10, and this buffer valve is used to open and close the buffer inlet at the top of the buffer bin 10. The buffer valve of this embodiment is preferably a pneumatic valve, and the buffer inlet is automatically opened and closed by controlling the pneumatic valve, which is convenient for operation.

[0032] The buffer inlet of the buffer bin 10 is connected to the upstream bent powder transfer bin. When the buffer valve is opened, the bent powder transfer bin can be connected to the buffer bin 10, and the bent powder in the transfer bin can enter the buffer bin 10 under the action of gravity; when the buffer valve is closed, the buffer bin 10 and the bent powder transfer bin are independent non-connected spaces.

[0033] The flow control mechanism of this embodiment includes a flow control bin 20 and a flow control component. For details, please refer to Figure 3 , the flow control bin 20 is preferably flat, and a flow control inlet 21 is opened at the top thereof, and a flow control outlet 22 is opened at the bottom of the flow control bin 20. The flow control inlet 21 is communicated with the buffer outlet of the buffer bin 10 for allowing bent powder to enter the flow control bin 20. The flow control outlet 22 is arranged offset from the flow control inlet 21 in the vertical direction, so that the flow control inlet 21 and the flow control outlet 22 are spaced apart in the horizontal direction to prevent the bent powder entering the flow control bin 20 from directly leaving the flow control bin 20 through the flow control outlet 22.

[0034] The flow control component of this embodiment is used to control the supply speed of the powder. The flow control component preferably includes a flow control motor and a screw conveyor. The screw conveyor is rotatably arranged in the flow control bin 20, and the flow control motor is fixedly arranged on the flow control bin 20 to drive the screw conveyor to rotate. When the flow control motor drives the screw conveyor to rotate at different speeds, the screw conveyor can supply the bent powder at the flow control opening to the flow control outlet 22 at different speeds, thereby achieving the purpose of flow control.

[0035] The loading pipeline 30 of this embodiment is used to guide the koji powder to the packaging bag. The top of the loading pipeline 30 is communicated with the flow control outlet 22, and the bottom of the loading pipeline 30 is used to connect to the packaging bag. Connecting the loading pipeline 30 to the bag mouth of the packaging bag during the loading process can effectively improve the situation of koji powder leaking between the loading pipeline 30 and the bag mouth, help improve the working environment, and reduce the waste of koji powder.

[0036] The clamping mechanism 40 of this embodiment is arranged at the bottom of the loading pipeline 30. The clamping mechanism 40 is used to clamp the bag mouth of the packaging bag tightly during the loading process to ensure a tight connection between the loading pipeline 30 and the bag mouth. The clamping mechanism 40 of this embodiment preferably includes a clamping and releasing airbag. The clamping and releasing airbag expands outwards during inflation to clamp the bag mouth; the clamping and releasing airbag contracts inwards during deflation to release the bag mouth of the packaging bag. By expanding and contracting the clamping and releasing airbag to correspondingly clamp or loosen the bag mouth, it is not only convenient to control but also can effectively prevent the clamping mechanism 40 from damaging the bag mouth of the packaging bag. It should be noted that the specific shape of the clamping and releasing airbag can be determined according to the shape of the bag mouth of the packaging bag. The operation methods for inflating and deflating the clamping and releasing airbag and the control components involved are prior art, so they will not be elaborated in this embodiment.

[0037] The conveying mechanism of this embodiment includes a conveying component and a lifting component. The conveying component conveys the packaging bag horizontally close to or away from the lower part of the loading pipeline 30, and the lifting component drives the packaging bag to approach and move away from the loading pipeline 30 vertically. Before loading, first use the conveying component to convey the packaging bag to directly below the loading pipeline 30; then use the lifting component to control the packaging bag to lift upwards so that the bag mouth of the packaging bag is connected to the bottom of the loading pipeline 30; during the loading process, the lifting component controls the packaging bag to gradually move downwards; after the packaging bag is loaded, the bag mouth of the packaging bag is disconnected from the loading pipeline 30, and the lifting component is used to control the packaging bag to fall downwards so that the bottom of the packaging bag contacts the conveying component; finally, use the conveying component to convey the packaging bag away from the lower part of the loading pipeline 30. The conveying mechanism automatically conveys the packaging bag to or away from the loading position, reducing the operation of manually handling the packaging bag during the koji powder packing process. It can not only improve work efficiency, reduce labor intensity, but also ensure safety.

[0038] When starting to load, the distance between the packaging bag and the bottom of the loading pipeline 30 is relatively close, and the koji powder will fall into the packaging bag at a relatively small distance; during the loading process, the koji powder in the packaging bag will gradually accumulate, and the packaging bag will also gradually descend. The distance at which the koji powder falls into the packaging bag during the entire loading process is relatively small and approximately the same, which can reduce the dust generated by the falling of the koji powder, thereby improving the problem of dust leakage.

[0039] The conveying component of this embodiment preferably includes a conveying bracket 50, a conveying roller 51, and a conveying motor 52. The conveying bracket 50 is in a frame shape. The conveying rollers 51 are arranged at intervals in the radial direction inside the conveying bracket 50. Both ends of the conveying roller 51 are rotatably connected to the conveying bracket 50. The conveying motor 52 is fixed on the conveying bracket 50. The conveying motor 52 drives the conveying roller 51 to rotate through a transmission gear and a transmission chain. The rotating conveying roller 51 can drive the packaging bag thereon to move horizontally.

[0040] The lifting component of this embodiment preferably includes a lifting base 61 and a lifting cylinder 60. The lifting base 61 is movably arranged directly below the loading pipe 30. The bottom of the lifting base 61 may optionally include a number of support rollers arranged at intervals. The support rollers are arranged parallel to the conveying rollers 51 and are located between the conveying rollers 51. The support rollers will not interfere with the conveying rollers 51, avoiding affecting the conveying and lifting of the packaging bag. The lifting cylinder 60 is fixedly arranged above the lifting base 61. The lifting cylinder 60 is connected to the lifting base 61 through a transmission rod 62. The telescopic movement of the lifting cylinder 60 is used to drive the lifting base 61 to move up and down. The conveying mechanism of this embodiment can automatically convey the packaging bag to be connected to the loading pipe 30, which helps to improve the production efficiency and further enhance the automation degree of the koji powder packaging.

[0041] The lifting base 61 of this embodiment is provided with a retaining wall 63. The retaining wall 63 leaves an opening on the side connecting the conveying component for the packaging bag to reach and leave the lifting base 61. The retaining wall 63 can effectively prevent the packaging bag from tipping over and ensure the stability of the packaging bag during the loading process. It should be noted that the lifting cylinder 60 of this embodiment is connected with a gas supply pipe, and the gas supply pipe is connected to a solenoid valve to control the opening and closing of the lifting cylinder 60. Since the control method of the lifting cylinder 60 is a prior art, it will not be elaborated in this embodiment.

[0042] The buffer bin 10 of this embodiment is provided with a fluidizing mechanism. The fluidizing mechanism is preferably close to the bottom of the buffer bin 10. It includes a fluidizing air pipe 11 extending into the buffer bin 10. The part of the fluidizing air pipe 11 extending into the buffer bin 10 is provided with air holes. The gas in the fluidizing air pipe 11 is blown into the buffer bin 10 through the air holes, which can effectively prevent the koji powder from clogging, avoid the koji powder from bridging, and ensure that the koji powder in the buffer bin 10 smoothly enters the flow control bin 20. A throttle valve and a check valve are also provided on the fluidizing air pipe 11 of this embodiment. The throttle valve is used to control the gas flow rate, and the check valve is used to control the gas flow direction.

[0043] In this embodiment, a recycling mechanism is provided on the flow control bin 20. This recycling mechanism is used to collect the spilled koji powder during the bag packaging process and convey the collected koji powder into the flow control bin 20. It can not only improve the working environment but also reduce the waste of koji powder. The recycling mechanism in this embodiment preferably includes a fan, an air inlet pipe 23, and an air outlet pipe 24. The fan provides power for the recycling mechanism. The air inlet pipe 23 is used to guide the dust to the inside of the recycling mechanism, and the air outlet pipe 24 is used to guide the dust to the flow control bin 20. The air inlet pipe 23 is preferably connected above the flow control outlet 22, and the air inlet pipe 23 communicates with the loading pipe 30 through the flow control outlet 22. The air outlet pipe 24 is preferably connected below the flow control inlet 21. It should be noted that the principle of using a fan to generate negative pressure to adsorb dust is a prior art. In some embodiments, filters and various valves can also be selected to meet actual needs.

[0044] The control system of this embodiment includes a metering sensor 70 and a controller. The metering sensor 70 is used to detect the loading amount information of the packaging bag and feedback it to the controller. The controller controls the buffer valve of the buffer bin 10, the flow control mechanism, the clamping mechanism 40, the conveying mechanism, the fluidization mechanism, and the recycling mechanism based on the loading amount information, so that the various components of the powder packaging device cooperate with each other.

[0045] The metering sensor 70 in this embodiment is preferably arranged at the lifting cylinder 60. The metering sensor 70 calculates the weight of the packaging bag by detecting the pulling force of the lifting cylinder 60, so as to accurately obtain the loading amount of the packaging bag. The controller in this embodiment is preferably a PLC controller. The controller adjusts the opening and closing of the buffer valve of the buffer bin 10 according to the loading amount of the packaging bag, adjusts the opening and closing of the fluidization air pipe 11 of the fluidization mechanism and the ventilation speed, adjusts the feeding speed of the flow control components of the flow control mechanism, adjusts the clamping and releasing operations of the clamping mechanism 40, adjusts the conveying speed and the lifting speed of the packaging bag of the conveying mechanism, and adjusts the opening and closing of the fan of the recycling mechanism. Especially during the loading process, the lifting assembly can adjust the downward movement speed of the packaging bag according to the change of the loading amount, which can effectively reduce the dust generated by the koji powder and ensure the accurate metering of packaging. It should be noted that the principle of using a controller to control various driving parts and valves is a prior art, and this embodiment will not be elaborated.

[0046] The buffer bin 10, the flow control bin 20, and the lifting cylinder 60 in this embodiment are all fixedly arranged on the frame 80. The specific shape of the frame 80 can be adaptively modified according to the layout of the components of the powder packaging device, so this embodiment will not be elaborated.

[0047] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as within the scope described in this specification.

[0048] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
