Description

Technical Field

[0001] This application relates to the field of material conveying, and more particularly to a material conveying system. Background Technology

[0002] Nowadays, beverages such as milk tea and juice are usually stored in a large container and transported from the container to the outlet by a pump. However, existing material conveying devices typically only have one container for storing beverages. Once all the beverages in the container have been transported, the conveying process needs to be paused and a new container filled with beverages needs to be replaced. This results in low conveying efficiency for the material conveying device, which cannot keep up with the current booming market environment. Utility Model Content

[0003] This application provides a material conveying system to solve the problem of low conveying efficiency in existing material conveying devices.

[0004] In a first aspect, embodiments of this application provide a material conveying system, including:

[0005] First liquid storage container and second liquid storage container;

[0006] The system comprises a first conveying pipe, a second conveying pipe, and a third conveying pipe. One end of the first conveying pipe is connected to the first liquid storage container, one end of the second conveying pipe is connected to the second liquid storage container, and the other ends of the first and second conveying pipes are simultaneously connected to one end of the third conveying pipe. The other end of the third conveying pipe is connected to the liquid outlet of the material conveying system.

[0008] A detection device is disposed at one end of the third delivery pipe near the liquid outlet and is communicatively connected to the switching component.

[0009] In one embodiment, the switching component includes a fixing member, a first abutting member, and a second abutting member, both of which are connected to the fixing member and located on opposite sides of the fixing member; wherein

[0010] The first abutment member is rotatably configured relative to the first conveying pipe to abut or not abut against the first conveying pipe; or

[0011] The second abutment is rotatably configured relative to the second conveying pipe to abut or not abut against the second conveying pipe.

[0012] In one embodiment, the angle formed by the first abutting member, the second abutting member, and the fixing member is 90° to 180°.

[0013] In one embodiment, the switching assembly further includes a detection element connected to the outer surface of the fixing member, and the material conveying system includes at least one detection element disposed circumferentially on the fixing member; wherein, when the motor drives the switching assembly to rotate, the detection element can be detected by the detection element to stop the switching assembly from rotating.

[0014] In one embodiment, a protrusion is formed on the outer surface of the first abutment / second abutment; wherein

[0015] When the first abutting member abuts against the first conveying pipe, the protrusion of the first abutting member contacts the outer surface of the first conveying pipe; or

[0016] When the second abutment abuts against the second conveying pipe, the protrusion of the second abutment contacts the outer surface of the second conveying pipe.

[0017] In one embodiment, the material conveying system includes a flow guiding assembly, which includes a fixed base and a third abutment member. The third abutment member is connected to the fixed base and located on one side of the fixed base. The third abutment member contacts the third conveying pipe and is rotatably disposed relative to the third conveying pipe.

[0018] In some embodiments, the material conveying system further includes a housing, within which the first conveying pipe, the second conveying pipe, and the third conveying pipe are all disposed; an abutment wall is formed on the side of the housing facing the third conveying pipe, the abutment wall including an abutment section, and a third abutment member capable of contacting the third conveying pipe to make the third conveying pipe contact the abutment section; the abutment section includes a first wall segment, a second wall segment, and a third wall segment continuously disposed, the second wall segment being disposed along the width direction of the material conveying system corresponding to the third conveying pipe, and the first wall segment and the third wall segment being located at opposite ends of the second wall segment; wherein

[0019] The second wall segment is recessed relative to the abutment wall, while the first wall segment and the third wall segment are protruding relative to the abutment wall.

[0020] In some embodiments, in the width direction of the material conveying system, when the third conveying pipe contacts the abutment section, the rotation angle of the third abutment member is within ±50°.

[0021] In one embodiment, the detection device is sleeved on the third delivery pipe, and the detection device is an ultrasonic sensor / bubble sensor, which is used to detect the liquid in the third delivery pipe.

[0022] In one embodiment, the first conveying pipe, the second conveying pipe, and the third conveying pipe are integrally formed.

[0023] The material conveying system provided in this application includes a first liquid storage container, a second liquid storage container, a first conveying pipe, a second conveying pipe, and a third conveying pipe.

At the same time, the other ends of the first and second conveying pipes are connected to one end of the third conveying pipe, and the other end of the third conveying pipe is connected to the liquid outlet of the material conveying system, thereby achieving the purpose of conveying the beverage in the first / second liquid storage container through the first and second conveying pipes.

[0024] The material conveying system also includes a switching component, which can selectively abut against the first conveying pipe, the second conveying pipe, or neither. Specifically, in this embodiment, when the first and second liquid storage containers contain the same beverage, the switching component can first abut against the first conveying pipe and restrict the liquid discharge from the first liquid storage container; and when the liquid in the second liquid storage container has been completely transferred through the second and third conveying pipes, the switching component can then abut against the second conveying pipe and restrict the liquid discharge from the first liquid storage container. At this time, the liquid in the first liquid storage container can be transferred to the outlet through the first and third conveying pipes. While the first liquid storage container is transferring liquid, a new second liquid storage container can be manually replaced so that the liquid in the first liquid storage container can be transferred to the new container after it has been completely transferred. Furthermore, the switching component can be controlled to not abut against either the first or second conveying pipe, which can increase the flow rate at the outlet to meet the discharge demand.

[0025] The material conveying system provided in this embodiment has the function of continuously conveying beverages, avoiding the problem that the material conveying device usually only places one container for storing beverages, and when all the beverages in the container are conveyed, it is necessary to stop the conveying and replace it with a new container containing beverages, thus further improving the conveying efficiency. Furthermore, the material conveying system provided in this embodiment also includes a detection device, which is set at the end of the third conveying pipe near the liquid outlet and is communicatively connected to the switching component to realize the continuous liquid dispensing function of the material conveying system and save manpower through automation.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] This application provides a material conveying system 100. Please refer to [link / reference]. Figure 1 The material conveying system 100 provided in this embodiment includes a first liquid storage container 111 and a second liquid storage container 112, which are used to store the same or different liquids. The material conveying system 100 also includes a first conveying pipe 121, a second conveying pipe 122 and a third conveying pipe 123. One end of the first conveying pipe 121 is connected to the first liquid storage container 111, one end of the second conveying pipe 122 is connected to the second liquid storage container 112, and the other ends of the first and second conveying pipes 121 and 122 are connected to one end of the third conveying pipe 123. The other end of the third conveying pipe 123 is connected to the liquid outlet 113 of the material conveying system 100, thereby achieving the purpose of transferring the liquid in the first liquid storage container 111 / second liquid storage container 112 through the first and second conveying pipes 121 and 122.

[0044] At the same time, please combine Figures 2-4 In this embodiment, the material conveying system 100 further includes a switching component 130. The switching component 130 can selectively abut against the first conveying pipe 121, or against the second conveying pipe 122, or neither against the first conveying pipe 121 nor against the second conveying pipe 122. Specifically, in this embodiment, when the first liquid storage container 111 and the second liquid storage container 112 contain the same liquid, the switching component 130 can first abut against the first conveying pipe 121 and restrict the discharge of liquid from the first liquid storage container 111 (e.g., ...). Figure 2 (as shown); and when the liquid in the second storage container 112 has been completely transferred through the second delivery pipe 122 and the third delivery pipe 123, the switching component 130 can then abut against the second delivery pipe 122 and restrict the discharge of liquid from the first storage container 111 (as shown). Figure 3As shown), at this time, the liquid in the first liquid storage container 111 can be transferred to the outlet 113 through the first delivery pipe 121 and the third delivery pipe 123. While the first liquid storage container 111 is transferring liquid, a new second liquid storage container 112 can be manually replaced so that after the liquid in the first liquid storage container 111 is exhausted, the liquid in the replaced second liquid storage container 112 can be transferred. At the same time, the switching component 130 can be controlled to not abut against the first delivery pipe 121 and the second delivery pipe 122 as needed. At this time, the flow rate of the outlet 113 can be increased to meet the liquid discharge requirements.

[0045] It should be noted that when the first liquid storage container 111 and the second liquid storage container 112 contain different liquids, the function of mixing liquids or single liquids can also be realized by switching component 130, so as to realize the functional diversity of material conveying system 100.

[0046] The material conveying system 100 provided in this embodiment has the function of continuous liquid conveying, which avoids the problem that the material conveying device usually only has one container for storing liquid, and when all the liquid in the container is conveyed, it is necessary to stop the conveying and replace it with a new container for storing liquid, thus further improving the conveying efficiency.

[0047] Furthermore, the material conveying system 100 provided in this embodiment also includes a detection device, which is disposed at one end of the third conveying pipe 123 near the liquid outlet 113 and is communicatively connected to the switching component 130 to realize the real-time detection function of the liquid outlet 113. Specifically, since the detection device in this embodiment is located at the end of the third conveying pipe 123 near the outlet 113, when the first liquid storage container 111 / second liquid storage container 112 transmits liquid to the outlet 113, the detection device can detect whether the transmitted medium is liquid or gas, so as to determine whether a new first liquid storage container 111 / second liquid storage container 112 needs to be replaced. For example, when the liquid in the first liquid storage container 111 / second liquid storage container 112 is sufficient, the transmitted medium is liquid, and when the liquid in the first liquid storage container 111 / second liquid storage container 112 is exhausted, the medium transmitted to the outlet 113 is gas or a gas-liquid mixture. At this time, since the detection device and the switching component 130 are connected in communication, the switching component 130 can automatically switch to abut against the first conveying pipe 121 / second conveying pipe 122 to realize the continuous liquid discharge function of the material conveying system 100 and save manpower through automation.

[0048] It should be noted that the detection device in this embodiment is fitted with a third delivery pipe 123, and the detection device can be an ultrasonic sensor or a bubble sensor or other detection instrument used to detect gas and liquid, which is not limited here.

[0049] In some embodiments, please refer to Figures 2-4 and combined Figure 1 The material conveying system 100 includes a first motor 114, which is connected to a switching assembly 130 and can drive the switching assembly 130 to rotate. The switching assembly 130 includes a fixing member 131, a first abutting member 132, and a second abutting member 133. The first abutting member 132 and the second abutting member 133 are both connected to the fixing member 131 and are located on opposite sides of the fixing member 131. The first motor 114 can drive the switching assembly 130 to rotate, so that the first abutting member 132 is rotatably configured relative to the first conveying pipe 121 to abut or not to abut the first conveying pipe 121, and the second abutting member 133 is rotatably configured relative to the second conveying pipe 122 to abut or not to abut the second conveying pipe 122, thereby realizing the function of abutting the first conveying pipe 121 / second conveying pipe 122.

[0050] In other embodiments of this application, the first abutment 132 and the second abutment 133 are also capable of rotating relative to the fixing member 131 to guide the liquid in the first conveying pipe 121 and the second conveying pipe 122. In addition, the material conveying system 100 also includes a third motor 116 and a conveying assembly 140 connected to each other. The third motor 116 can drive the conveying assembly 140 to rotate to guide the liquid in the third conveying pipe 123 to the outlet 113. At the same time, the material conveying system 100 also includes a housing 124, which is used to accommodate the switching assembly 130 and the conveying assembly 140.

[0051] In some embodiments, the angle formed by the first abutment 132, the second abutment 133, and the fixing member 131 is 170° to 190°. By placing the first abutment 132 and the second abutment on both sides of the fixing member 131, the situation where the first abutment 132 and the second abutment 133 are too close and interfere with each other can be avoided, thereby further ensuring the stability of the material conveying system 100 during operation.

[0052] In some embodiments, such as Figures 2-4 As shown, the switching component 130 also includes a detection element 150, which is connected to the outer surface of the fixing element 131. The material conveying system 100 includes at least one detection element 150, which is disposed around the fixing element 131. In this embodiment, when the first motor 114 drives the switching component 130 to rotate, the fixing element 131 and the detection element 150 will rotate accordingly. When the detection element 150 rotates to the detection element 150 position, the first motor 114 will stop working and the switching component 130 will stop rotating, so as to achieve the purpose of abutting against the first conveying pipe 121 / second conveying pipe 122, or neither abutting against the first conveying pipe 121 and the second conveying pipe 122.

[0053] For example, in this embodiment, three detection elements 150 may be included. One of them is used to position the first abutment 132 abutting against the first conveying pipe 121 and the second abutment 133 not abutting against the second conveying pipe 122. Another detection element 150 is used to position the second abutment 133 abutting against the second conveying pipe 122 and the first abutment 132 not abutting against the first conveying pipe 121. The last detection element 150 is used to position the first abutment 132 and the second abutment 133 evenly abutting against the first conveying pipe 121 and the second conveying pipe 122. It can be understood that when the detected element 150 is rotated to the corresponding detection element 150, the functions mentioned above can be achieved.

[0054] In one specific embodiment, each detection element 150 is provided with a detection channel 151 for the detection element 150 to pass through. When the detection element 150 passes through, the detection element 150 can detect the detection element 150 to realize the corresponding function. In addition, the detection function can also be realized by light emission and light reception.

[0055] In some embodiments, the outer surfaces of the first abutment 132 and the second abutment 133 are formed with protrusions. These protrusions are used to ensure a tighter fit between the first abutment 132 and the second abutment 133 and the first conveying pipe 121 and the second conveying pipe 122, thereby achieving a better flow-limiting effect. Specifically, when the first abutment 132 abuts against the first conveying pipe 121, the protrusion of the first abutment 132 faces the first conveying pipe 121 and contacts the outer surface of the first conveying pipe 121; when the second abutment 133 abuts against the second conveying pipe 122, the protrusion of the second abutment 133 faces the second conveying pipe 122 and contacts the outer surface of the second conveying pipe 122.

[0056] In some embodiments, in the arrangement direction of the first conveying pipe 121 and the first abutment 132, the projections of the first abutment 132 and the first conveying pipe 121 overlap, thereby increasing the contact area between the first abutment 132 and the first conveying pipe 121 and achieving a better flow restriction effect on the first conveying pipe 121. Similarly, in the arrangement direction of the second conveying pipe 122 and the first abutment 132, the projections of the second abutment 133 and the second conveying pipe 122 overlap, thereby increasing the contact area between the second abutment 133 and the second conveying pipe 122 and achieving a better flow restriction effect on the second conveying pipe 122.

[0057] In some embodiments, the projections of the first conveying pipe 121 and the second conveying pipe 122 at least partially overlap in the height direction of the material conveying system 100, thereby optimizing the lateral dimensions of the material conveying system 100 and thus optimizing the overall volume of the material conveying system 100.

[0058] In some embodiments, such as Figure 1 and Figure 5 As shown, the material conveying system 100 includes a second motor 115 and a flow guiding assembly 160 connected to each other. The second motor 115 can drive the flow guiding assembly 160 to rotate. The flow guiding assembly 160 includes a fixed base 161 and a third abutment 162. The third abutment 162 is connected to the fixed base 161 and is located on one side of the fixed base 161. When the second motor 115 drives the flow guiding assembly 160 to rotate, the third abutment 162 will also rotate and contact the third conveying pipe 123 to guide the liquid in the third conveying pipe 123 to the outlet 113.

[0059] Furthermore, such as Figure 6 As shown, the material conveying system 100 also includes a housing 170, in which the first conveying pipe 121, the second conveying pipe 122, and the third conveying pipe 123 are all disposed. Meanwhile, an abutment wall 171 is formed on the side of the housing 170 facing the third conveying pipe 123. The abutment wall 171 includes an abutment section 172, wherein the third abutment member 162 can contact the third conveying pipe 123 so that the third conveying pipe 123 contacts the abutment section 172, thereby achieving the guiding effect of the liquid in the third conveying pipe 123.

[0060] Please continue to refer to Figure 6 The abutment section 172 includes a first wall section 173, a second wall section 174, and a third wall section 175 continuously arranged. The second wall section 174 is arranged along the width direction of the material conveying system 100 corresponding to the third conveying pipe 123. The first wall section 173 and the third wall section 175 are located at both ends of the second wall section 174. The second wall section 174 is recessed relative to the abutment wall 171, while the first wall section 173 and the third wall section 175 protrude relative to the abutment wall 171, thereby allowing the first wall section 173 and the third wall section 175 at both ends of the second wall section 174 to pass through. The third abutment 162 is positioned so that when the third abutment 162 rotates around the fixed base 161 relative to the third conveying pipe 123, it can still contact the protruding first wall section 173 and the third wall section 175, whether it passes the second wall section 174 or not (i.e., when the angle between the fixed base 161, the third abutment 162, and the abutment wall 171 is an acute or obtuse angle). This extends the guiding path of the liquid in the third conveying pipe 123 and achieves a more efficient juice extraction effect for the material conveying system.

[0061] In a further embodiment, such as Figure 6 As shown, in the width direction of the material conveying system 100, when the third conveying pipe 123 contacts the abutment section 172, the rotation angle range of the third abutment member 162 is within ±50°.

[0062] In some embodiments, the material conveying system 100 includes a seal, which is fitted at the connection between the first conveying pipe 121, the second conveying pipe 122, and the third conveying pipe 123 to prevent liquid leakage in the conveying pipes and improve the user experience of the material conveying system 100. In other embodiments of this application, the first conveying pipe 121, the second conveying pipe 122, and the third conveying pipe 123 may also be integrally formed, thereby further improving the overall strength of the material conveying system 100 and ensuring operational reliability.
