Description

Technical Field

[0001] This utility model relates to the technical field of material feeding adjustment equipment, specifically to a multi-channel discharge accuracy adjustment device. Background Technology

[0002] Existing liquid beverage preparation (also known as formulation) devices such as milk tea machines and coffee machines need to transport a wide variety of raw materials and ensure accurate quantitative measurement in each channel.

[0003] Patent application number CN202310425313.0 discloses a milk tea machine and a method for precise ingredient dispensing. The technical solution is as follows: A milk tea machine for precise ingredient dispensing includes a machine body with several weighing units inside, each weighing unit having a raw material cylinder. A feeding box is connected to the machine body, and the feeding box has a feeding port. Each of the raw material cylinders is connected to a pump body, the output end of which is connected to the feeding port. A weighing unit located below the feeding port in the feeding box is used to place milk tea cups. The machine also includes a control unit, with the weighing units below the raw material cylinders, the weighing units below the milk tea cups, and the pump bodies all connected to the control unit via signal connections. Existing methods for achieving precise dispensing of milk tea ingredients include calibrating the time-flow rate relationship of each dispensing channel and controlling the pump operating time and flow rate to control the dispensing quantity; or weighing each channel separately and then combining the weights. This invention calibrates the feeding time of each ingredient through a weighing unit and a control unit below the ingredient cylinder, and controls the total weight of the milk tea through a weighing unit below the milk tea cup. This ensures that the ratio and total weight of the milk tea added each time meet the requirements, enabling precise ingredient mixing and guaranteeing a consistent milk tea flavor.

[0004] However, in practical use, the difficulty lies in the fact that the pumps, valves, and pipes that transport liquids constantly change with environmental factors such as time, temperature, and air pressure. To maintain accuracy, frequent calibration is required. The calibration process is time-consuming and labor-intensive, affecting normal material output. Furthermore, the increase in the number of channels makes manual calibration impractical, significantly increasing calibration time and difficulty. Utility Model Content

[0005] The purpose of this invention is to provide a multi-channel discharge accuracy adjustment device, which can effectively solve the technical problems of high calibration difficulty and long calibration time caused by the increase in the number of raw material channels in the prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A multi-channel discharge accuracy adjustment device includes a weighing device, which is used to weigh the discharge mass of the discharge unit of the equipment body;

[0008] The discharge unit includes a multi-channel fluid converging port and a controller. The discharge pipe in the multi-channel fluid converging port is used to connect to the silo. A pump or valve is installed between the discharge pipe and the silo. The pump and weighing device are connected to the controller. The controller is used to read the weighing data of the weighing device and control the material flow by controlling the pump or valve.

[0009] The weighing device is an electronic scale, which is either a platform scale located below or above the multi-channel fluid converging port.

[0010] Furthermore, the main body of the equipment is a coffee machine or a milk tea machine.

[0011] Furthermore, the pump is a peristaltic pump, a gear pump, or a rotary pump, etc.

[0012] Furthermore, the valve includes a solenoid valve.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves material discharge calibration through a weighing device in practical use. During operation, the weighing device weighs the material in the receiving container. The material enters the receiving container under the action of a pump, and the weighing device performs real-time weighing. The calibrated channel can discharge material synchronously. After a period of time, each pump can be driven individually, recording the running time and the increment of the weighing device. The time-flow relationship can be calculated to calibrate the channel. The controller reads the weighing data and controls the material flow by controlling the pumps or valves, thus completing the calibration work simultaneously with normal material discharge. This invention effectively solves the technical problems of increased calibration difficulty and time caused by the increased number of raw material channels in existing technologies.

[0029] Example 1

[0030] This embodiment discloses a multi-channel discharge accuracy adjustment device, including a weighing device 101, which is used to weigh the discharge mass of the discharge unit 103 of the equipment body 102.

[0031] The discharge unit 103 includes a multi-channel fluid converging port 105 and a controller. The discharge pipe 111 in the multi-channel fluid converging port 105 is used to connect to the silo 108. A pump 107 or a valve is provided between the discharge pipe 111 and the silo 108. The pump 107 or the valve and the weighing device 101 are connected to the controller. The controller is used to read the weighing data of the weighing device 101 and control the material flow by controlling the pump 107 or the valve.

[0032] The weighing device 101 is an electronic scale, which is either a platform scale located below the multi-channel fluid converging port 105 or a hanging scale located above it.

[0033] Furthermore, the main body of the device 102 is a coffee machine or a milk tea machine.

[0034] Furthermore, in some preferred embodiments, a detection unit is installed on the device body 102, which is used to detect the amount of material in the silo 108.

[0035] Wherein, the pump 107 is a peristaltic pump 107; the valve is a solenoid valve.

[0036] To facilitate a better understanding of this invention by those skilled in the art, the following detailed description is provided in conjunction with specific implementation examples.

[0037] See Figure 1-Figure 4 This embodiment discloses a multi-channel discharge accuracy adjustment device, including a weighing device 101. The weighing device 101 is used to be installed below the discharge unit 103 of the equipment body 102, and can be a platform scale.

[0038] The weighing device 101 is connected to the discharge unit 103.

[0039] In actual use, a display screen 104 can be installed on the main body of the device 102 to display the weighing data. In actual use, the parameters can also be adjusted, which will not be described in detail here.

[0040] The discharge unit 103 includes a multi-channel fluid converging port 105, a pipe 106, a pump 107, a hopper 108, and a controller. The multi-channel fluid converging port 105 is fixedly installed on the equipment body 102 and located above the weighing device 101. Each discharge pipe 111 of the multi-channel fluid converging port 105 is correspondingly connected to a hopper 108 through a pipe 106. Each pipe 106 is equipped with a pump 107. The weighing device 101, the pump 107, and the controller are connected.

[0041] The weighing device 101 is an electronic platform scale.

[0042] Furthermore, the pump 107 is a peristaltic pump 107.

[0043] The pipe 106 is a flexible hose.

[0044] Furthermore, the main body of the device 102 is a coffee machine or a milk tea machine.

[0045] In practical use, this invention achieves material discharge calibration through a weighing device 101. During use, the receiving container 117 is placed on the weighing device 101. Material enters the receiving container 117 from the hopper 108 under the action of the pump 107. After entering the weighing device 101, the material is weighed in real time. The calibrated channel can discharge material synchronously. After a period of time, one pump can be driven independently, and the running time and the increment of the weighing device 101 can be recorded. The time-flow relationship can be calculated to calibrate this channel. Thus, calibration is completed simultaneously with normal material discharge. This invention effectively solves the technical problems of high calibration difficulty and long calibration time caused by the increase in the number of raw material channels in existing technologies.

[0046] In practical use, this invention allows for independent calibration of each channel during idle periods, or calibration of one channel during each material discharge. After calibration, the other channels can discharge simultaneously, thus improving calibration efficiency.

[0047] In this embodiment, the controller is mainly used to control the start and stop of pump 107 and its start-up duration. The weighing device 101 is used to realize real-time weighing of materials. During calibration, pump 107 in the corresponding channel is started, and material will be pumped out of pump 107 within a certain period of time. At this time, there will be a theoretical material value, and the weighing device 101 will also have a real-time material value. The controller compares the theoretical material value with the real-time material value. If it is within the allowable error range, calibration is not required. If the error is large, calibration is performed. During calibration, the output per unit time is calculated by comparing the real-time material value with the output time, thus achieving the purpose of calibration. In actual use, this utility model does not involve improvement of the method; the calculation method involved can adopt the method in the prior art.

[0048] Furthermore, a detection unit is installed on the device body 102, which is used to detect the amount of material in the hopper 108. The detection unit can be a liquid level sensor, used to realize real-time detection of the material in the hopper 108.

[0049] In some preferred embodiments, the multi-channel fluid converging port 105 includes a substrate 109, on which a plurality of mounting holes 110 are provided, and a discharge pipe 111 is fixedly installed in each mounting hole 110; the discharge pipe 111 includes a mounting section 112 and a connecting section 113, which are connected by an arc transition and form a bend 114 at the connection, so that the connecting section 113 of the discharge pipe 111 is inclined in a direction away from the center of the substrate 109. The substrate 109 is mounted on the device body 102, and the discharge pipe 111 and the pipe 106 correspond one-to-one and are connected to each other.

[0050] The discharge pipe 111 is used to handle various materials. Since the discharge pipe 111 includes an installation section 112 and a connecting section 113, the installation section 112 and the connecting section 113 are connected by an arc transition and a bend 114 is formed at the connection, so that the connecting section 113 of the discharge pipe 111 is inclined in a direction away from the center of the substrate 109.

[0051] This allows the upper end of the discharge pipe 111 to form a chrysanthemum-shaped structure that spreads outwards, while a concentrated structure is formed at the base plate 109. This satisfies the requirement to reduce the radial size of the discharge port and also creates a larger operating space at the upper end of the discharge pipe 111, which is suitable for hose installation and improves the space for later maintenance operations.

[0052] Furthermore, in some preferred embodiments, the mounting holes 110 are divided into multiple groups, and each group of mounting holes 110 is arranged in a circular array on the substrate 109. The distance between the center of each group of mounting holes 110 and the center of the substrate 109 increases sequentially, so that the multiple groups of mounting holes 110 form a layered distribution structure on the substrate 109. This arrangement makes the arrangement of the discharge pipe 111 more regular.

[0053] Furthermore, the bending arc of the discharge tube 111 bend 114 near the center of the substrate 109 is smaller than that of the discharge tube 111 bend 114 far from the center of the substrate 109. This allows the outer discharge tube 111 to be more inclined, thereby creating a larger operating space.

[0054] Furthermore, the connecting section 113 of the discharge pipe 111 is provided with a continuous stepped structure 115, and the pipe 106 is fitted onto the continuous stepped structure 115. The continuous stepped structure 115 formed can provide better anti-detachment and multiple sealing effects for the hose, thereby improving assembly efficiency and sealing effect.

[0055] Furthermore, a guide slope 116 is provided at the end of the connecting section 113 of the discharge pipe 111. The guide slope 116 can serve as a guide, facilitating the installation of the hose.

[0056] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
