Description

Technical Field

[0001] The invention relates to the technical field of dosing machines, in particular to a liquid dosing machine. Background Art

[0002] Liquid dosing machines are mainly used for quantitative liquid output. In the food field, fructose dosing machines are a type of liquid dosing machine, which is used to add quantitative fructose to beverages. It is a dosing machine that can control the amount of fructose output and maintain a consistent amount of fructose output. It can also quantify a variety of different types of sugar and add appropriate amounts of fructose according to different beverage requirements.

[0003] Fructose exists in the form of an oily viscous liquid under natural conditions. The density of fructose is greatly affected by temperature. The lower the temperature, the greater the density of the fructose syrup becomes and the slower the fluidity becomes. Therefore, it affects the sugar output within the unit of the dosing machine. In order to improve the accuracy of the sugar output, the existing dosing machine is equipped with an electronic scale and a control mechanism. The electronic scale is set below the sugar outlet of the dosing machine. The density and viscosity of the syrup are analyzed and calculated by the electronic scale and the control mechanism, and then the output calibration is realized to ensure the accuracy of the sugar output. However, the electronic scale is used for weighing and calibration. On the one hand, it will cause a waste of syrup. On the other hand, in order to ensure accuracy, the liquid storage cylinder needs to be recalibrated before use each time it is refilled. The operation process is cumbersome. In addition, when the existing liquid dosing machine is replenished with syrup, the whole barrel of syrup is directly poured into the liquid dosing machine. The temperature of the newly poured syrup is neutralized with the temperature of the remaining syrup in the liquid dosing machine, resulting in a sudden drop in the temperature of the syrup in the liquid dosing machine. It takes a long time to heat the syrup in the liquid dosing machine. When the beverage shop is busy, the waiting time for heating will greatly reduce the efficiency of beverage making and affect the user experience. Summary of the invention

[0030] Embodiment 1

[0031] When a liquid metering machine discharges a certain amount of liquid, a metering pump and other components are generally used to discharge the liquid at the same flow rate per unit time. However, for liquids whose density is greatly affected by temperature, such as syrup, oil, glue, etc., if the liquid temperature changes significantly during liquid discharge, the flow rate of the liquid per unit time will change, thereby failing to ensure the stability of the liquid discharge from the metering machine. In this embodiment, syrup is taken as an example for the following explanation.

[0032] Reference Figures 1 to 3, is a liquid quantitative machine provided by the present invention, comprising a heat preservation cylinder 1, an automatic liquid replenishing mechanism 2, a baffle 3, a temperature control mechanism 4 and a discharging mechanism 5, wherein the heat preservation cylinder 1 is used to store syrup, the automatic liquid replenishing mechanism 2 and the discharging mechanism 5 are both connected to the heat preservation cylinder 1, the automatic liquid replenishing mechanism 2 is in contact with the syrup in the heat preservation cylinder 1 or fixed at a predetermined position, the predetermined position is: the liquid replenishing position of the automatic liquid replenishing mechanism 2, when the syrup is lower than the predetermined position, the automatic liquid replenishing mechanism 2 immediately decides to open, replenishes the heat preservation cylinder 1, and when the syrup reaches the predetermined position, the automatic liquid replenishing mechanism 2 Close, stop replenishing the liquid to the insulation cylinder 1. It should be further explained that the predetermined position is set at the upper part of the insulation cylinder 1. The setting height of the predetermined position can at least ensure that when the insulation cylinder 1 is replenished with sugar in real time, the temperature stability of the syrup in the insulation cylinder 1 can be maintained by heating the temperature control mechanism 4. Furthermore, the automatic replenishing mechanism 2 replenishes the insulation cylinder 1 according to the height change of the syrup in the insulation cylinder 1. In this embodiment, the automatic replenishing mechanism 2 can be a variety of structures for replenishing liquid. For example, the automatic replenishing mechanism 2 is an active structure that can change height with the syrup liquid level. When the automatic sealing structure is movable, the movable sealing structure is placed in the syrup, and the position of the movable sealing structure can change as the amount of syrup increases; when the automatic liquid replenishing mechanism 2 is fixed at a predetermined position, the automatic liquid replenishing mechanism 2 can be provided with a sensor for sensing the liquid level position at the upper part of the heat preservation cylinder 1, and the liquid replenishing process is controlled by the sensor. The automatic liquid replenishing mechanism 2 automatically replenishes the liquid according to the remaining amount in the heat preservation cylinder 1, and the temperature control mechanism 4 is connected to the heat preservation cylinder 1 to control the temperature of the syrup in the heat preservation cylinder 1. The replenished syrup flows into the upper part of the heat preservation cylinder 1. Since the replenished syrup has a relatively high temperature, the replenished syrup The temperature control mechanism 4 keeps the temperature of the syrup in the insulation cylinder 1 stable, the discharging mechanism 5 is connected to the bottom of the insulation cylinder 1 and extends into the insulation cylinder 1, the outlet of the discharging mechanism 5 is arranged on the upper part of the syrup, when the low-temperature syrup flows into the lower part of the insulation cylinder 1, the high-temperature syrup flows out from the discharging mechanism 5 located at the upper part, which can ensure the high temperature of the discharged syrup, and the horizontal height of the discharging mechanism 5 is lower than the horizontal height of the automatic liquid replenishing mechanism 2, which can realize that after the syrup is discharged from the discharging mechanism 5, the automatic liquid replenishing mechanism 2 continues to replenish liquid, and the continuity of liquid discharge and replenishment of the liquid dosing machine can be realized.

[0033] It should be noted that the liquid metering machine in the present embodiment replenishes the syrup in real time according to the remaining amount of syrup in the insulation cylinder 1. The newly replenished syrup has a lower temperature and a higher density, so it sinks to the bottom of the insulation cylinder 1. The syrup with a higher temperature in the upper part flows into the discharge mechanism 5, and the temperature control mechanism 4 keeps the temperature of the syrup in the insulation cylinder 1 warm, thereby ensuring that the temperature of the syrup flowing into the discharge mechanism 5 remains at a high level. In the present embodiment, a quantitative pumping mechanism may be provided at the bottom of the discharge mechanism 5, such as a diaphragm pump, to achieve quantitative discharge of the syrup. Traditional diaphragm pumps use a timed discharge method to ensure quantitative discharge. Therefore, when the syrup flowing into the discharge mechanism 5 in real time is a liquid with a higher temperature, it can prevent the syrup from solidifying and hanging on the wall, and ensure the stability of the syrup flow rate, thereby ensuring the stability of the quantitative discharge of sugar by the discharge mechanism 5.

[0034] In one embodiment, referring to Figure 1 The liquid dosing machine also includes a liquid storage tank 6, which is arranged on the top of the insulation cylinder 1, and the automatic liquid replenishing mechanism 2 is connected to the liquid storage tank 6. A first liquid outlet 610 is arranged at the bottom of the liquid storage tank 6. The automatic liquid replenishing mechanism 2 closes / opens the first liquid outlet 610 according to the height of the syrup in the insulation cylinder 1. The liquid storage tank 6 replenishes the insulation cylinder 1 with liquid through the automatic liquid replenishing mechanism 2. Since the existing syrups are all in barrels, when the original barreled syrup is added to the original liquid dosing machine, on the one hand, it will cause the dosing machine to add too much material at one time, and the temperature of the syrup in the liquid dosing machine is too low, and quantitative sugar cannot be discharged. On the other hand, it may also cause the barreled syrup to be opened and left over, causing waste. The liquid storage tank 6 in this embodiment can realize real-time liquid replenishment through the automatic liquid replenishing mechanism 2, and the amount of liquid replenishment per unit time is small, which is conducive to heating and temperature control by the temperature control mechanism 4 to avoid the syrup temperature in the insulation cylinder 1 being too low. In addition, the liquid storage tank 6 can directly use barreled syrup to avoid waste.

[0035] In one embodiment, referring to Figure 1 The discharging mechanism 5 is arranged at the bottom of the heat preservation cylinder 1, and the discharging mechanism 5 at least includes a baffle 3 and a second liquid outlet 510. The baffle 3 is connected to the inner wall of the bottom of the heat preservation cylinder 1 to divide the heat preservation cylinder 1 into two parts: a heat preservation chamber 110 and a liquid outlet chamber 120. The automatic liquid replenishing mechanism 2 is arranged in the heat preservation chamber 110, and the automatic liquid replenishing mechanism 2 replenishes the heat preservation cylinder 1. The second liquid outlet 510 is arranged at the bottom of the liquid outlet chamber 120 to discharge the syrup. The heat preservation chamber 110 and the upper part of the liquid outlet chamber 120 are interconnected. The high-temperature syrup originally floating in the heat preservation cylinder 1 flows into the liquid outlet chamber 120 from the interconnected position at the upper part of the heat preservation chamber 110. The heat preservation chamber 110 and the lower part of the liquid outlet chamber 120 are separated by the baffle 3 to prevent the newly added low-temperature syrup from flowing into the liquid outlet chamber 120. The temperature control mechanism 4 is connected to the heat preservation chamber 110 to control the temperature of the syrup in the heat preservation chamber 110.

[0036] In one embodiment, the baffle 3 is installed in the vertical direction, and the height of the top surface of the baffle 3 in the vertical direction is lower than the height of the bottom surface of the first liquid outlet 6 in the vertical direction. Without affecting the automatic liquid replenishment of the insulation chamber 110 by the automatic liquid replenishment mechanism 2, the syrup in the insulation chamber 110 flows from the upper part of the baffle 3 to the liquid outlet chamber 120. The syrup flowing into the liquid outlet chamber 120 is the syrup with a higher temperature located in the upper part of the insulation chamber 110, thereby ensuring the high temperature of the syrup in the liquid outlet chamber 120.

[0037] In one embodiment, the baffle 3 is connected to the bottom of the liquid storage cylinder 6. Different from the above-mentioned embodiment, an opening is arranged on the baffle 3 in this embodiment, and the height of the opening in the vertical direction is lower than the height of the bottom surface of the first liquid outlet 6 in the vertical direction. Furthermore, mutually cooperating slide grooves are arranged between the baffle 3 and the liquid storage cylinder 6, and the baffle 3 is detachably arranged on the liquid storage cylinder 6 to facilitate the installation and disassembly of the baffle 3.

[0038] It should be noted that the height of the baffle 3 or the height of the opening set on the baffle 3 is positively correlated with the volume of the liquid outlet chamber 120. The larger the volume of the liquid outlet chamber 120, the higher the height of the baffle 3 or the height of the opening set on the baffle 3. When the height of the baffle 3 or the height of the opening set on the baffle 3 is higher, the height of the syrup flowing into the liquid outlet chamber 120 is higher, and the influence of the temperature of the replenished syrup is smaller. Therefore, the higher the temperature of the syrup flowing into the liquid outlet chamber 120, the easier it is to ensure the quantitative accuracy. Furthermore, as a preferred embodiment, the height of the baffle 3 or the height of the opening set on the baffle 3 is: the maximum height of the syrup flowing from the insulation chamber 110 into the liquid outlet chamber 120 under the premise of maintaining a certain flow rate and high temperature of the syrup in the liquid dosing machine.

[0039] As a preferred embodiment, the outer wall of the baffle 3 and the inner wall of the insulation cylinder 1 are provided with mutually cooperating sliding connectors, the baffle 3 is limited by the bottom of the liquid storage cylinder 6 and / or the inner wall of the insulation cylinder 1, and a sealing structure is provided in the sliding connector to ensure the sealing between the baffle 3 and the inner wall of the insulation cylinder 1, thereby preventing the syrup from flowing through the gap between the baffle 3 and the insulation cylinder 1 and affecting the temperature of the syrup.

[0040] In one embodiment, the discharging mechanism 5 is arranged at the bottom of the heat-insulating cylinder 1 and extends toward the inside of the heat-insulating cylinder 1. However, unlike the above-mentioned discharging mechanism 5, in this embodiment, the baffle 3 in the discharging mechanism 5 is replaced by a liquid outlet extension portion, and the second liquid outlet 510 is arranged at the bottom of the heat-insulating cylinder 1. One end of the liquid outlet extension portion is connected to the second liquid outlet 510, and the horizontal height of the other end of the liquid outlet extension portion is lower than the horizontal height of the automatic liquid replenishing mechanism 2. Unlike the above-mentioned embodiment, the discharging mechanism 5 in this embodiment is not provided with a baffle 3, and the extended liquid outlet extension portion is directly extended into the heat-insulating cylinder 1 at the second liquid outlet 510, thereby raising the sugar outlet position and ensuring the high temperature of the sugar outlet. This embodiment is suitable for situations where a small amount of sugar outlet is required.

[0041] In one embodiment, referring to Figure 2 and 3 The automatic liquid replenishing mechanism 2 at least includes a float 210 and a guide portion 220. The float 210 is arranged at the lower part of the first liquid outlet 610 and is arranged. The float 210 is fixedly connected to the guide portion 220. The guide portion 220 is rotatably connected to the bottom of the liquid storage tank 6. The height of the float 210 in the vertical direction changes with the change of the remaining amount of syrup. When the height of the float 210 in the vertical direction gradually increases, the guide portion 220 is driven to rotate. The float 210 or the guide portion 220 seals the first liquid outlet 610. It should be noted that the float 210 and the guide portion 220 The part 220 can be arranged in a variety of ways: 1. The float 210 is used as a sealing device, and the diameter of the float 210 is not less than the diameter of the first liquid outlet 610. The syrup flows into the insulation chamber 110 from the first liquid outlet 610, and the syrup liquid level in the insulation chamber 110 rises, driving the float 210 to rise. When the float 210 rises to the first liquid outlet 610, it can block the first liquid outlet 610 and stop the liquid discharge. The syrup flows into the liquid outlet chamber 120 from the upper part of the baffle 3, and the syrup liquid level in the insulation chamber 110 drops, driving the float 210 to drop, and the first liquid outlet 610 is closed. 10 is opened to start the liquid replenishment, wherein the guide part 220 guides the float 210 to the first liquid outlet 610. In this embodiment, the guide part 220 is a cross bar fixed to the bottom of the liquid storage tank 6, and the float 210 is fixed on the guide part 220 to achieve the limit of the float 210; (2) the float 210 is used as a sealing device, and the guide part 220 can also be a tubular structure. The float 210 is arranged in the pipeline of the guide part 220, and one end of the guide part 220 is connected to the first liquid outlet 610. The float 210 floats in the pipeline of the guide part 220, and further The side wall of the guide portion 220 is also provided with a circulation portion for the syrup to circulate; (3) a sealing member is also provided on the guide portion 220, and the sealing member is also fixed on the guide portion 220. The float 210 drives the sealing member to move up and down as the syrup liquid level changes, and the sealing member seals the first liquid outlet 610. The automatic liquid replenishing mechanism 2 in this embodiment replenishes liquid in time when the syrup liquid level in the insulation chamber 110 does not reach the first liquid outlet 610. On the one hand, real-time liquid replenishment can be achieved, and on the other hand, the amount of liquid replenishment is small, which also reduces the influence of liquid replenishment on the temperature of the syrup in the insulation chamber 110.

[0042] In one embodiment, referring to Figure 3The automatic liquid replenishing mechanism 2 at least includes a ventilation pipe 230. When the automatic liquid replenishing mechanism 2 includes the ventilation pipe 230, the liquid storage cylinder 6 and the heat preservation cylinder 1 are sealed and connected. The ventilation pipe 230 connects the liquid storage cylinder 6 and the heat preservation chamber 110. One end opening of the ventilation pipe 230 extends to the top of the liquid storage cylinder 6, and the opening position is higher than the syrup liquid level in the liquid storage cylinder 6. The other end opening of the ventilation pipe 230 extends into the heat preservation chamber 110. The end opening of the ventilation pipe 230 extending into the heat preservation chamber 110 is higher in the vertical direction than the first liquid outlet. The height of the first liquid outlet 610 in the vertical direction is that when the syrup liquid level in the insulation chamber 110 reaches the first liquid outlet 610, since the ventilation pipe 230 connects the insulation chamber 110 and the air inside the liquid storage cylinder 6, the syrup seals the first liquid outlet 610 at the bottom of the liquid storage cylinder 6, and the liquid storage cylinder 6 stops discharging liquid due to the air pressure balance; when the syrup liquid level in the insulation chamber 110 does not reach the first liquid outlet 610, the syrup flows into the insulation chamber 110 for liquid replenishment. The automatic liquid replenishment mechanism 2 utilizes the principle of gas balance, the device structure is simple, and there are fewer dead angles, which is easy to clean.

[0043] In one embodiment, the temperature control mechanism 4 includes a temperature measuring part and a heating part, both of which are arranged at the bottom of the insulation chamber 110. The temperature measuring part is a temperature sensor, which is arranged on the inner side of the insulation chamber 110. Since the syrup for rehydration will flow to the bottom of the insulation chamber 110, the temperature of the syrup at the bottom of the insulation chamber 110 decreases. The temperature measuring part is arranged at the bottom of the inner side of the insulation chamber 110, which can better respond to the change of the temperature of the syrup in the insulation chamber 110. The heating part is arranged on the outer side of the insulation chamber 110. In this embodiment, the heating part is a resistance wire structure. After the resistance wire is energized, it heats the syrup in the insulation chamber 110. The temperature measuring part and the heating part are connected. When the temperature measured by the temperature measuring part is lower than the preset sugar temperature, the heating part is energized and starts heating. When the temperature measured by the temperature measuring part reaches the preset sugar temperature, the heating part stops heating, and the density is controlled by controlling the temperature of the syrup.
