Description

Technical Field

[0001] This application relates to the field of dispensing equipment, and more particularly to a powder mixing and dispensing equipment. Background Technology

[0002] Powder mixing equipment is used to mix powder and liquid evenly. When powder is added to the powder mixing equipment, the equipment is in a stopped state so that dust is not easily raised. However, when liquid is added to the powder mixing equipment, in order to prevent the powder from clumping, the powder mixing equipment must be in a running state, that is, the liquid is added and stirred at the same time to ensure that the powder and liquid are mixed evenly.

[0003] However, during the process of adding liquid to the powder mixing equipment, the powder mixing equipment is prone to stirring up a large amount of powder while in operation, which increases the consumption of powder and thus reduces the output of powder. Utility Model Content

[0004] In order to improve the problem of powder being easily stirred up when the powder mixing equipment is in operation, this application provides a powder mixing and dispensing equipment.

[0005] This application provides a powder mixing and dispensing device, which adopts the following technical solution:

[0006] A powder mixing and dispensing device includes a housing, a cover, a stirring paddle, a water inlet pipe, and a metering pump. The housing has a mixing chamber for mixing the powder. The stirring paddle is rotatably connected to the inner wall of the mixing chamber. The cover is rotatably connected to the surface of the housing and covers the mixing chamber. One end of the water inlet pipe is connected to the surface of the housing and communicates with the mixing chamber. The other end of the water inlet pipe is connected to the water outlet of the metering pump. The water inlet of the metering pump is connected to a liquid storage tank. The metering pump drives the liquid in the liquid storage tank to enter the mixing chamber through the water inlet pipe.

[0007] By adopting the above technical solution, when the powder mixing and dispensing equipment is in use, the cover is driven to rotate away from the mixing chamber, the sealing effect of the cover on the mixing chamber disappears, and the powder is poured into the mixing chamber, realizing the feeding of powder. The cover is driven to rotate closer to the mixing chamber, and the outer peripheral surface of the cover presses against the inner wall of the mixing chamber and seals the mixing chamber. When liquid needs to be fed, the metering pump drives the liquid in the storage tank to enter the mixing chamber through the water inlet pipe. The stirring paddle rotates on the inner wall of the mixing chamber, so that the liquid and powder are mixed evenly. The outer peripheral surface of the cover presses against the inner wall of the mixing chamber and seals the mixing chamber, so that the powder in the mixing chamber is not easily blown out of the mixing chamber when it is raised, reducing the loss of powder and thus improving the output of powder.

[0008] Optionally, the housing is connected to a power assembly, which includes a power motor, at least two drive wheels, and a drive belt used in conjunction with the drive wheels. The power motor is connected to the outer wall of the housing, and the motor axis of the power motor and the rotation axis of the stirring paddle are parallel to each other. The end of the rotation axis of the stirring paddle passes through the outer wall of the housing and is coaxially fixed on the rotation axis of one of the drive wheels. The other drive wheel is coaxially fixed on the motor shaft of the power motor, and the drive belt tensions and connects the two drive wheels.

[0009] By adopting the above technical solution, one of the transmission wheels is coaxially fixed on the rotating shaft of the stirring paddle, and the other transmission wheel is coaxially fixed on the motor shaft of the power motor. The transmission belt tensions and connects the two transmission wheels. When the power motor runs, it drives the stirring paddle to rotate on the inner wall of the stirring chamber, thereby ensuring the stability of the stirring paddle's rotation on the inner wall of the stirring chamber.

[0010] Optionally, the housing is connected to a discharge assembly, which includes an elastic hopper, a discharge hopper, and a discharge pipe. The discharge pipe is connected to the bottom of the housing, and the inner cavity of the discharge pipe communicates with the inner cavity of the mixing chamber. The discharge hopper is connected to the bottom of the housing, and the inlet of the discharge hopper faces the outlet of the discharge pipe. The powder in the mixing chamber enters the inner cavity of the discharge hopper through the discharge pipe. One end of the elastic hopper is coaxially sleeved on the outer circumferential surface of the discharge pipe, and the other end of the elastic hopper faces the inner cavity of the discharge hopper. The powder in the discharge pipe is guided along the inner wall of the elastic hopper into the inner cavity of the discharge hopper.

[0011] By adopting the above technical solution, when the powder in the mixing chamber is stirred, the powder in the mixing chamber enters the inner cavity of the elastic hopper through the discharge pipe. The inner wall of the elastic hopper guides the powder into the inner cavity of the discharge hopper, making it less likely for the powder to be thrown up, further reducing the loss of powder, thereby increasing the output of powder.

[0012] Optionally, the surface of the discharge hopper is provided with a viewing groove spaced apart. The viewing groove penetrates the outer wall of the discharge hopper and connects to the inner cavity of the discharge hopper. A viewing film is connected to the inner wall of the viewing groove.

[0013] By adopting the above technical solution, the visual slot is connected to the inner cavity of the discharge hopper, and the visual film is connected to the inner wall of the visual slot. The staff can observe the discharge of powder in the discharge hopper through the visual film, which makes it less likely for the powder to be blown into the staff's eyes, thereby improving the safety of the staff.

[0014] Optionally, it also includes a dispensing assembly, which includes a dispensing frame, a dispensing tube, and a discharge screw. The dispensing tube is connected to the surface of the discharge hopper, and the inner cavity of the dispensing tube communicates with the inner cavity of the discharge hopper. The discharge screw is rotatably connected to the inner wall of the dispensing tube. The discharge screw rotates on the inner wall of the dispensing tube and drives the powder in the discharge hopper to be discharged from the dispensing tube. The inner cavity of the dispensing frame is for embedding a powder storage bag. The opening of the powder storage bag is folded towards the outer peripheral surface of the dispensing frame, and the inner cavity of the powder storage bag faces the opening of the dispensing tube.

[0015] By adopting the above technical solution, when the powder accumulates in the inner cavity of the discharge hopper, the powder storage bag is embedded in the inner cavity of the dispensing frame, the opening of the powder storage bag is folded towards the outer peripheral surface of the dispensing frame, the inner cavity of the powder storage bag faces the opening of the dispensing pipe, the discharge screw rotates on the inner wall of the dispensing pipe, and drives the powder in the discharge hopper to be discharged from the dispensing pipe and enter the inner cavity of the powder storage bag, thereby realizing the directional dispensing of the powder.

[0016] Optionally, the dispensing assembly further includes an elastic shielding hopper, one end of which is coaxially fitted onto the outer circumferential surface of the dispensing tube to form a seal, and the other end of which is fitted onto the outer circumferential surface of the dispensing frame to form a seal. The inner cavity of the elastic shielding hopper is connected to the inner cavity of the dispensing tube and the inner cavity of the powder storage bag.

[0017] By adopting the above technical solution, one end of the elastic shielding hopper is coaxially sleeved on the outer circumference of the dispensing tube to form a seal, and the other end of the elastic shielding hopper is sleeved on the outer circumference of the dispensing frame to form a seal. The inner cavity of the elastic shielding hopper is connected to the inner cavity of the dispensing tube and the inner cavity of the powder storage bag. The powder in the dispensing tube enters the inner cavity of the elastic shielding hopper, and the inner wall of the elastic shielding hopper guides the powder into the inner cavity of the powder storage bag, further reducing the amount of powder that is thrown up and detached from the powder storage bag, thereby improving the output of powder.

[0018] Optionally, the surface of the elastic shielding bucket is provided with a plurality of viewing grooves spaced apart, the viewing grooves are connected to the inner cavity of the elastic shielding bucket, and the inner wall of the viewing grooves is connected to a viewing membrane.

[0019] By adopting the above technical solution, the viewing slot is connected to the inner cavity of the elastic shielding bucket. Workers can observe the inner cavity of the elastic shielding bucket through the viewing film, which makes it less likely for powder to be blown into the workers' eyes, thereby improving the safety of workers.

[0020] Optionally, the dispensing assembly further includes a dispensing motor, at least two synchronous pulleys, and a synchronous belt used in conjunction with the synchronous pulleys. The dispensing motor is connected to the bottom of the discharge hopper, and the motor axis of the dispensing motor is parallel to the axis of the discharge screw. The end of the rotating shaft of the discharge screw passes through the outer wall of the discharge hopper and is coaxially connected to the rotating shaft of one of the synchronous pulleys. The other synchronous pulley is coaxially connected to the rotating shaft of the dispensing motor, and the synchronous belt tensions the two synchronous pulleys.

[0021] By adopting the above technical solution, one synchronous pulley is coaxially fixed on the rotating shaft of the discharge screw, and the other synchronous pulley is coaxially fixed on the motor shaft of the dispensing motor. The synchronous belt tensions and connects the two synchronous pulleys, driving the discharge screw to rotate on the inner wall of the dispensing tube, thereby improving the stability of the discharge screw rotating inside the dispensing tube.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The design of the cover, water inlet pipe, and metering pump body allows the agitator to rotate within the mixing chamber, ensuring uniform mixing of the liquid and powder. The outer circumference of the cover presses against the inner wall of the mixing chamber, sealing it and preventing the powder from being blown out when it is stirred, thus reducing powder loss and increasing powder output.

[0024] 2. The setup of the power motor, transmission wheel and transmission belt: the transmission belt is tensioned to connect the two transmission wheels. When the power motor is running, it drives the agitator to rotate on the inner wall of the mixing chamber, thereby ensuring the stability of the agitator's rotation on the inner wall of the mixing chamber.

[0025] 3. The design of the elastic hopper, discharge hopper, and discharge pipe allows the inner wall of the elastic hopper to guide the powder into the inner cavity of the discharge hopper, making it less likely for the powder to be thrown up, further reducing powder consumption and thus increasing powder output.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a powder mixing and dispensing device. (Refer to...) Figure 1 and Figure 2The powder mixing and dispensing equipment includes a housing 1, a cover 2, a stirring paddle 3, a water inlet pipe 4, a metering pump 5, and a dispensing assembly 6. The bottom of the housing 1 abuts against the ground to form a support, and the top of the housing 1 has a mixing chamber 11 for mixing the powder. The cover 2 is rotatably connected to the inner wall of the mixing chamber 11, and the axis of rotation of the cover 2 is parallel to the length direction of the housing 1. When the cover 2 rotates towards the mixing chamber 11, the outer circumference of the cover 2 presses against the inner wall of the mixing chamber 11 to form a seal. The stirring paddle 3 is rotatably connected to the inner wall of the mixing chamber 11, and the axis of rotation of the stirring paddle 3 is parallel to the inner wall of the mixing chamber 11. The inlet pipe 4 is parallel to the length of the tank 1. One end of the inlet pipe 4 is fixed to the surface of the tank 1, and the inner cavity of the inlet pipe 4 is connected to the inner cavity of the mixing chamber 11. The other end of the inlet pipe 4 is connected to the outlet of the metering pump body 5. The inlet of the metering pump body 5 is connected to the storage tank. The directional pump body drives the liquid in the storage tank to enter and exit the mixing chamber 11 in a metered manner through the inlet pipe 4. The stirring paddle 3 rotates on the inner wall of the mixing chamber 11, which drives the powder and liquid to mix evenly. The powder in the mixing chamber 11 is not easy to be discharged from the mixing chamber 11, reducing the consumption of powder and thus increasing the output of powder.

[0031] Reference Figure 1 and Figure 2 The housing 1 is equipped with a discharge assembly 7, which is used to collect the uniformly mixed powder in the mixing chamber 11. The discharge assembly 7 includes an elastic hopper 71, a discharge hopper 72, and a discharge pipe 73. The end of the discharge pipe 73 is connected to the bottom of the housing 1, and the inner cavity of the discharge pipe 73 is connected to the mixing chamber 11. The discharge hopper 72 is fixed on the surface of the housing 1 facing the discharge pipe 73, and the opening of the discharge pipe 73 faces the inlet of the discharge hopper 72. The elastic hopper 71 can be made of rubber or silicone. In this embodiment, the elastic hopper 71 is made of rubber and has a certain deformation capacity. One end of the elastic hopper 71 is fitted onto the outer circumferential surface of the discharge pipe 73 to form a seal, and the other end of the elastic hopper 71 faces the inlet of the discharge hopper 72.

[0032] Reference Figure 1 and Figure 2 When the powder and liquid in the mixing chamber 11 are mixed evenly, the powder in the mixing chamber 11 enters the inner cavity of the elastic hopper 71 through the discharge pipe 73. The inner wall of the elastic hopper 71 guides the powder into the inner cavity of the discharge hopper 72, reducing the amount of powder thrown up into the inner cavity of the feed hopper, thereby reducing the consumption of powder. Multiple viewing grooves 711 are spaced apart on the outer circumference of the elastic hopper 71. The depth direction of the viewing grooves 711 penetrates the outer wall of the elastic hopper 71 and connects to the inner cavity of the elastic hopper 71. A viewing film 8 is connected to the inner wall of the viewing grooves 711. The material of the viewing film 8 can be plastic or rubber. In this embodiment, the material of the viewing film 8 is plastic, which has a certain deformation ability. The staff can observe the flow of powder in the elastic hopper 71 through the viewing film 8, making it less likely for the powder to enter the staff's eyes, thereby improving the safety of the staff.

[0033] Reference Figure 1 and Figure 2 The dispensing component 6 can sequentially dispense the powder in the discharge hopper 72 into the inner cavity of the powder storage bag. The dispensing component 6 includes a dispensing frame 61, a dispensing pipe 62, a discharge screw 63, an elastic shielding hopper 64, a dispensing motor 65, at least two synchronous pulleys 66, and a synchronous belt 67 used in conjunction with the synchronous pulleys 66. The end of the dispensing pipe 62 is connected to the surface of the discharge hopper 72, and the inner cavity of the dispensing pipe 62 is connected to the inner cavity of the discharge hopper 72. The discharge screw 63 is rotatably connected to the inner wall of the dispensing pipe 62. The discharge screw 63 rotates on the inner wall of the dispensing pipe 62 and drives the powder in the discharge hopper 72 to be discharged from the dispensing pipe 62.

[0034] Reference Figure 1 and Figure 2 The end of the rotating shaft of the discharge screw 63 passes through the outer wall of the discharge hopper 72. The dispensing motor 65 is fixed to the surface of the discharge hopper 72 by bolts. The motor axis of the dispensing motor 65 and the axis of the discharge screw 63 are parallel to each other. One synchronous pulley 66 is coaxially fixed on the rotating shaft of the discharge screw 63, and the other synchronous pulley 66 is coaxially fixed on the motor shaft of the dispensing motor 65. The synchronous belt 67 tensions and connects the two synchronous pulleys 66. When the dispensing motor 65 rotates, it drives the discharge screw 63 to rotate on the inner wall of the dispensing tube 62, thereby ensuring the stability of the rotation of the discharge screw 63.

[0035] Reference Figure 1 and Figure 2 The bottom of the dispensing frame 61 abuts against the ground to form support. The inner cavity of the dispensing frame 61 is for embedding the powder storage bag, and the opening of the powder storage bag is flipped and limited towards the outer circumferential surface of the dispensing frame 61. The inner cavity of the powder storage bag faces the opening of the dispensing tube 62. The elastic shielding hopper 64 can be made of rubber or silicone. In this embodiment, the elastic shielding hopper 64 is made of rubber, which has a certain deformation capacity. One end of the elastic shielding hopper 64 is fitted onto the outer circumferential surface of the dispensing tube 62 to form a seal, and the other end of the elastic shielding hopper 64 is fitted onto the outer circumferential surface of the dispensing frame 61 to form a seal. The inner cavity of the elastic shielding hopper 64 and the outer circumferential surface of the dispensing frame 61 abut against the opening of the powder storage bag to form a limit. The discharge screw 63 rotates on the inner wall of the dispensing tube 62, driving the powder in the discharge hopper 72 to enter the inner cavity of the elastic shielding hopper 64 through the dispensing tube 62. The inner wall of the elastic shielding hopper 64 guides the powder into the inner cavity of the powder storage bag, realizing the dispensing and storage of the powder.

[0036] Reference Figure 1 and Figure 2 The outer periphery of the elastic shielding hopper 64 is provided with a plurality of viewing grooves 641 spaced apart. The viewing grooves 641 penetrate the outer wall of the elastic shielding hopper 64 and connect to the inner cavity of the elastic shielding hopper 64 in the depth direction. A viewing membrane 9 is connected to the inner wall of the viewing groove 641. The material of the viewing membrane 9 can be plastic or rubber. In this embodiment, the material of the viewing membrane 9 is plastic, which has a certain deformation capability. The staff can observe the flow of powder in the inner cavity of the elastic shielding hopper 64 through the viewing membrane 9.

[0037] Reference Figure 1 and Figure 2 The housing 1 is equipped with a power assembly 10, which can drive the stirring paddle 3 to rotate on the inner wall of the stirring chamber 11. The power assembly 10 includes a power motor 101, at least two drive wheels 102, and a drive belt 103 used in conjunction with the drive wheels 102. The power motor 101 is fixed to the outer wall of the housing 1 by bolts. The motor axis of the power motor 101 and the rotation axis of the stirring paddle 3 are parallel to each other. The end of the rotation axis of the stirring paddle 3 passes through the outer wall of the housing 1. One drive wheel 102 is coaxially fixed on the rotation axis of the stirring paddle 3, and the other drive wheel 102 is coaxially fixed on the motor shaft of the power motor 101. The drive belt 103 tensions and connects the two drive wheels 102. When the power motor 101 is running, it drives the stirring paddle 3 to rotate on the inner wall of the stirring chamber 11, thereby improving the stability of the stirring paddle 3 rotating on the inner wall of the stirring chamber 11.

[0038] The implementation principle of the powder mixing and dispensing equipment in this application embodiment is as follows: When the powder mixing and dispensing equipment is in use, the cover 2 is driven to rotate away from the mixing chamber 11, and the sealing effect of the cover 2 on the mixing chamber 11 disappears, and the powder is poured into the mixing chamber 11 to realize the feeding of powder. The cover 2 is driven to rotate closer to the mixing chamber 11, and the outer peripheral surface of the cover 2 presses against the inner wall of the mixing chamber 11 and seals the mixing chamber 11. When it is necessary to feed liquid, the metering pump 5 drives the liquid in the storage tank to enter the mixing chamber 11 through the water inlet pipe 4. The stirring paddle 3 rotates on the inner wall of the mixing chamber 11 to make the liquid and powder mix evenly. The outer peripheral surface of the cover 2 presses against the inner wall of the mixing chamber 11 and seals the mixing chamber 11, so that the powder in the mixing chamber 11 is not easily blown out of the mixing chamber 11 when it is raised, reducing the loss of powder and thus improving the output of powder.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
