Description

Technical Field

[0001] This utility model relates to the technical field of dairy processing equipment, specifically to an automatic feeding cart for milk skin production. Background Technology

[0002] Milk skin is a traditional food originating from Inner Mongolia, China. It is made from fresh milk, which is placed in a metal container and heated over a low flame, allowing the moisture to slowly evaporate and eventually solidify into a yellow, round, cake-like milk skin at the bottom of the pot. With the continuous improvement of living standards in China, the demand for milk skin has increased significantly. The production method has also evolved from traditional small-scale, single-container manual processing to large-scale industrial production using milk skin machines with numerous containers.

[0003] However, when using existing milk skin machines with multiple containers for large-scale industrial production of milk skin, fresh milk needs to be manually added to numerous metal containers using milk ladles. This process presents three problems: 1. High labor intensity and low efficiency: When manually adding fresh milk to the metal containers, milk buckets are placed on a handcart. Workers push the handcart along the milk skin machine, using milk ladles to scoop fresh milk from the buckets into the metal containers one by one. As the amount of milk in the buckets decreases, workers need to frequently bend over to scoop more milk, resulting in high labor intensity and low efficiency; 2. Pollution of the production environment: Workers using milk ladles to scoop fresh milk into the metal containers... During milking, milk drips from the outer surface of the milk ladle onto the trolley, the ground, and the worktable of the milk skin machine. In summer, when the temperature is high, if the milk dripping from the trolley, the ground, and the worktable of the milk skin machine is not cleaned up in time, it will ferment and spoil, thus polluting the production environment. 3. The weight of the milk skin cannot be precisely controlled: The weight of each milk skin produced in large-scale industrial production is determined by the weight of fresh milk that the operator adds to the metal container with the milk ladle. However, the amount of fresh milk that the operator adds to the metal container with the milk ladle is determined by the operator's sense of feeling. The uncertainty of the operator's sense of feeling leads to the inability to precisely control the weight of the milk skin produced in the end.

[0004] The aforementioned problems affect the product quality and economic benefits of milk skin manufacturers. Therefore, how to solve these problems is a common technical issue currently faced by domestic milk skin manufacturers. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an automatic feeding vehicle for milk skin production, which replaces the manual addition of fresh milk to metal containers in the existing large-scale industrial production of milk skin, and solves the technical problems currently faced by domestic milk skin production enterprises, such as high labor intensity of operators, low work efficiency, pollution of the production environment, and inability to accurately control the weight of milk skin.

[0006] To achieve the aforementioned purpose, this utility model adopts the following technical solution: an automatic feeding cart for milk skin production, comprising a carrier, a milk storage tank, an electrical control box, and a feeding arm assembly, wherein the carrier is provided with wheels; the milk storage tank and the electrical control box are fixedly mounted on the upper part of the carrier, and the feeding arm assembly is hinged to the side wall of the milk storage tank or the electrical control box; a feeding pump is fixedly mounted on the milk storage tank or in the electrical control box, and a plurality of feeding pipes are provided in the feeding arm assembly, wherein the feeding pump and the feeding pipes are connected by pipelines, and the feeding pump is electrically connected to the electrical control box.

[0007] Furthermore, a feeding pump is provided; the feeding pump is connected to several feeding pipes through pipelines.

[0008] Preferably, there are several feeding pumps; each feeding pump is connected to a corresponding feeding pipe through a pipeline.

[0009] Furthermore, the electrical control box is connected to an external power source via a cable.

[0010] Preferably, the electrical control box is equipped with a storage battery.

[0011] Furthermore, the feeding arm assembly includes a hinge base, a hinge joint, a feeding arm, and a feeding tube. The hinge base is fixedly installed on the side wall of the milk storage box or the electrical control box. The feeding arm is fixedly connected to the hinge joint, and the hinge joint is rotatably connected to the hinge base through a hinge shaft. The feeding tube is fixedly connected to the feeding arm through a feeding tube bracket. A limit shaft is provided on the hinge base.

[0012] Furthermore, a solenoid valve is installed on the feeding pipe, and the solenoid valve is electrically connected to the electrical control box.

[0013] Furthermore, a feeding nozzle is provided at the lower end of the feeding pipe, and a splash-proof filter screen is installed in the feeding nozzle.

[0014] Furthermore, a liquid detection sensor is installed on the outside of the feeding pipe, and the liquid detection sensor is electrically connected to the electrical control box.

[0015] Furthermore, a liquid level sensor is installed on the milk storage box, and the liquid level sensor is electrically connected to the electrical control box.

[0016] Due to the adoption of the above-described technical solution, this utility model has the following beneficial effects: The automatic feeding cart for milk skin production disclosed in this utility model includes a carrier, a milk storage tank, an electrical control box, and a feeding arm assembly. The carrier is equipped with wheels at its lower part. The milk storage tank and the electrical control box are fixedly mounted on the upper part of the carrier. The feeding arm assembly is hinged to the side wall of the milk storage tank or the electrical control box. A feeding pump is fixedly mounted on the milk storage tank. Several feeding pipes are provided in the feeding arm assembly. The feeding pump and the feeding pipes are connected via pipelines. The feeding pump is electrically connected to the electrical control box. When the automatic feeding cart for milk skin production is working… With the feeding arm assembly extended, the operator pushes the carrier along the milk skin machine, aligns the feeding pipe with the metal container located on the upper part of the milk skin machine, and presses the feeding switch on the electrical control box. The electrical control box drives the feeding pump to run for a set time, automatically adding a fixed weight of fresh milk to several metal containers simultaneously through the feeding pipe. This replaces the manual work of scooping fresh milk from the milk bucket into the metal containers one by one with a milk ladle. Therefore, it reduces the labor intensity of the operators, improves the work efficiency, and also solves the problems of production environment pollution and inaccurate control of milk skin weight caused by manually adding milk with a milk ladle.

[0033] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. Example 1

[0034] An automatic feeding cart for milk skin production, see instruction manual attached. Figure 1 , 2 The system includes a carrier 1, a milk storage tank 2, an electrical control box 3, and a feeding arm assembly 4. The carrier 1 is equipped with rotatable wheels at its lower part. The milk storage tank 2 and the electrical control box 3 are fixedly mounted on the upper part of the carrier 1. A feeding pump 2.1 is fixedly mounted on the lower part of the side wall of the milk storage tank 2. The feeding pump 2.1 is a diaphragm pump, and its inlet is directly connected to the inner cavity of the milk storage tank 2. The top of the milk storage tank 2 has two milk inlets, and a cover 5 is movably mounted at each milk inlet. The feeding arm assembly 4 is a single unit that is hinged to one side wall of the milk storage tank 2.

[0035] See the instruction manual appendix Figure 3The feeding arm assembly 4 includes a hinge base 4.1, a hinge joint 4.2, a feeding arm 4.3, and a feeding pipe 4.4. The feeding arm 4.3 is made of aluminum alloy, and the feeding pipe 4.4 is made of non-metallic material (such as PVC or PE pipe). The hinge base 4.1 is a rectangular groove with through-holes on its upper and lower sides and two limiting holes. The hinge base 4.1 is fixedly welded to the side wall of the milk storage box 2 (or electrical control box 3). The hinge joint 4.2 is a rectangular block with through-holes on its upper and lower ends and a feeding arm groove. Bolt holes are provided on two opposite sides of the feeding arm groove. One end of the feeding arm 4.3 is positioned in the feeding arm groove of the hinge joint 4.2 and is fixedly connected to the hinge joint 4.2 by a locking block B4.11 and bolts. 4.2 The hinge joint 4.2 is set in the rectangular groove of the hinge seat 4.1, and the hinge hole of the hinge joint 4.2 corresponds to the hinge hole of the hinge seat 4.1. The hinge joint 4.2 and the hinge seat 4.1 are rotatably connected by the hinge shaft 4.7. The limiting hole of the hinge seat 4.1 is provided with a limiting shaft 4.8, and the outer circular surface of the limiting shaft 4.8 abuts against the outer surface of the hinge joint 4.2, restricting the hinge joint 4.2 from rotating around the hinge shaft 4.7. Four feeding tube supports 4.10 are fixedly set on the feeding arm 4.3 by locking block A4.9 and bolts. The feeding tube 4.4 is fixedly set on the outer end of the feeding tube support 4.10. The feeding pump 2.1 is connected to the feeding tube 4.4 through a silicone hose and a tee (the silicone hose and tee are not shown in the attached drawings of the instruction manual).

[0036] See the instruction manual appendix Figure 7 The electrical control box 3 contains an electrical control system, which includes a control module, a power conversion module, a drive power switch (IGBT), buttons, and a display screen. The control module is electrically connected to the buttons, display screen, and drive power switch. The power conversion module is electrically connected to the control module and drive power switch. The drive power switch is electrically connected to the feeding pump 2.1 via a cable. When the electrical control system is working, the power conversion module is connected to an external power source (AC220V) via a cable. The external AC power provides working power to the automatic feeding cart for milk skin production. The power conversion module converts the external AC power into corresponding DC power to provide working power to the control module and the feeding pump 2.1. The buttons are used to set various working parameters of the automatic feeding cart for milk skin production (such as the continuous working time set for each start of the feeding pump 2.1) and to start the feeding pump 2.1. The display screen is used to display various parameters and working status of the automatic feeding cart for milk skin production.

[0037] See the instruction manual appendix Figure 6A feeding nozzle 4.5 is fixedly installed at the lower end of the feeding pipe 4.4. A splash filter 4.12 is installed in the feeding nozzle 4.5. The splash filter 4.12 is composed of three layers of stainless steel filter screens with different mesh sizes, and the mesh size of the stainless steel filter screens increases from top to bottom, forming a foamer. When fresh milk flows through the splash filter 4.12, the three layers of stainless steel filter screens with different mesh sizes will mix the fresh milk with air to form a foamy fresh milk flow, reducing the impact force of the fresh milk flow and preventing the fresh milk from splashing and contaminating the worktable of the milk skin machine 6 when it is poured into the metal container 7. In addition, when the feeding pump 2.1 stops working, the stainless steel filter screen at the bottom, due to its higher mesh size, will give the fresh milk remaining at the port of the feeding nozzle 4.5 a higher surface tension, preventing the fresh milk remaining in the feeding pipe 4.4 from dripping, thus solving the problem of environmental pollution that is easy to occur during the production of milk skin.

[0038] See the instruction manual appendix Figure 1 , 4 15 shows the setting status of the feeding arm assembly 4 when the automatic feeding cart for milk skin production is working; when the automatic feeding cart for milk skin production is working, the outer surfaces of the two limit shafts 4.8 respectively abut against the two sides of the hinge joint 4.2, and the feeding arm 4.3 is perpendicular to the side wall of the milk storage tank 2; when the operator pushes the carrier 1 along the milk skin machine 6, when the feeding pipe 4.4 is aligned with the metal container 7 set on the upper part of the milk skin machine 6, the feeding switch (button) on the electrical control box is pressed, and the control module controls the opening of the drive power switch at the set time (i.e., the running time set by the feeding pump 2.1), the power conversion module is connected to the feeding pump 2.1, and the feeding pump 2.1 is driven to run, and the feeding pump 2.1 fills the milk storage tank Fresh milk in step 2 is pumped through silicone hoses to each feeding pipe 4.4. Each feeding pipe 4.4 automatically adds fresh milk to the corresponding metal container 7. The weight of fresh milk added to each metal container 7 is determined by the running time set by the feeding pump 2.1, thus ensuring precise control of the weight of the produced milk skin. After a row of metal containers 7 has been filled with fresh milk, the operator pushes the cart 1 to continue moving along the milk skin machine 6, repeating the above process until all metal containers 7 on the milk skin machine 6 have been filled with fresh milk. Using this automatic feeding cart for milk skin production replaces the manual work of scooping fresh milk from the milk bucket into the metal containers one by one with a milk ladle, which greatly reduces the labor intensity of the operators and improves the work efficiency.

[0039] See the instruction manual appendix Figure 2 , 515 shows the setting state of the feeding arm assembly 4 when the automatic feeding cart for milk skin production is adding fresh milk to the milk storage tank 2; when the automatic feeding cart for milk skin production is adding fresh milk to the milk storage tank 2, the limiting shaft 4.8 adjacent to the electrical control box 3 is pulled out, the feeding arm 4.3 is rotated so that the feeding arm 4.3 is parallel to the side wall of the milk storage tank 2, and then the limiting shaft 4.8 is inserted back so that the outer surface of the limiting shaft 4.8 abuts against the outer surface of the hinge joint 4.2, restricting the rotation of the feeding arm 4.3; the cover 5 of the milk filling port on the top of the milk storage tank 2 is opened, and the milk storage tank 8 adds fresh milk to the milk storage tank 2 through the milk filling port. Example 2

[0040] See the instruction manual appendix Figure 8 , 9 In this embodiment, the automatic feeding cart for milk skin production has two feeding arm assemblies 4, which are respectively hinged to the side walls of the milk storage tank 2 (or the electrical control box 3). In addition, four feeding pumps 2.1 are fixedly installed on the lower part of both side walls of the milk storage tank 2. Liquid level sensors are installed inside or outside the milk storage tank 2. When the liquid level sensor is installed inside the milk storage tank 2, a pressure liquid level sensor is used. When the liquid level sensor is installed outside the milk storage tank 2, a capacitive liquid level sensor is used. In this case, a window in a non-metallic area needs to be set on the outer wall of the milk storage tank 2, and the capacitive liquid level sensor is attached to the window in the non-metallic area.

[0041] See the instruction manual appendix Figure 10 In this embodiment, a liquid detection sensor 4.6 is also provided on the feeding pipe 4.4. Each feeding pump 2.1 is connected to the corresponding feeding pipe 4.4 through an independent silicone hose (the silicone hose is not shown in the attached drawings). The purpose of setting up an independent feeding pump 2.1 for each feeding pipe 4.4 in this embodiment is to solve the problem that when one feeding pump 2.1 pumps fresh milk to multiple feeding pipes 4.4 through multiple milk delivery hoses, the resistance encountered by the fresh milk in the milk delivery hoses is also different because the length of the milk delivery hoses corresponding to each feeding pipe 4.4 is different. Therefore, the resistance encountered by the fresh milk in the milk delivery hoses is also different for different feeding pipes 4.4. .4 The problem of large weight deviation and inability to adjust and control when adding fresh milk to metal container 7; When each feeding pipe 4.4 is independently equipped with a feeding pump 2.1, the weight of fresh milk added to metal container 7 by each feeding pipe 4.4 is related to the working flow rate of feeding pump 2.1 (the inherent working parameters of feeding pump 2.1) and the continuous working time during each milk addition (the adjustment parameters of the automatic feeding cart for milk skin production). Therefore, the weight of fresh milk added to metal container 7 by each feeding pipe 4.4 can be precisely controlled by adjusting the working parameters of the automatic feeding cart for milk skin production.

[0042] See the instruction manual appendix Figure 13In this embodiment, the electronic control system includes a control module, a power conversion module, a battery, a charging module, drive power switches, buttons, and a display screen. Several drive power switches are provided. The control module is electrically connected to the buttons, display screen, and drive power switches. The charging module, battery, and power conversion module are sequentially electrically connected. The power conversion module is electrically connected to the control module and drive power switches. Eight drive power switches are electrically connected to their corresponding feed pumps 2.1 via cables. Eight liquid detection sensors 4.6 and a liquid level sensor are electrically connected to the control module via cables. During operation, the charging module connects to an external power source to charge the battery, and the power conversion module converts the battery voltage to a corresponding voltage to provide power to the control module and the feeding pump 2.1. The buttons are used to set various operating parameters of the automatic milk skin production feeding cart (such as the continuous working time set for each start of the feeding pump 2.1) and to start the feeding pump 2.1. The display screen is used to display various parameters and operating status of the automatic milk skin production feeding cart. The liquid detection sensor is used to detect whether there is fresh milk in the feeding pipe 4.4. The liquid level sensor is used to detect the liquid level of fresh milk in the milk storage tank 2.

[0043] See the instruction manual appendix Figure 8 , 4 14 shows the setting status of the feeding arm assembly 4 when the automatic feeding cart for milk skin production is working; the working process of the automatic feeding cart for milk skin production in this embodiment is the same as that in embodiment one. Compared with embodiment one, the automatic feeding cart for milk skin production in this embodiment has an automatic alarm function for insufficient milk storage tank 2 during operation. When the liquid detection sensor detects that there is no fresh milk in the feeding pipe 4.4, or when the liquid level sensor detects that the fresh milk level in the milk storage tank 2 is lower than the set value, an alarm signal will be issued to remind the operator to replenish fresh milk in the milk storage tank 2 in time.

[0044] See the instruction manual appendix Figure 9 , 11 Figure 15 shows the setting state of the feeding arm assembly 4 when the automatic milk skin production feeding cart adds fresh milk to the milk storage tank 2. The process of adding fresh milk to the milk storage tank 2 by the automatic milk skin production feeding cart is the same as in Embodiment 1. It should be noted that after each addition of fresh milk to the milk storage tank 2 by the automatic milk skin production feeding cart in this embodiment, an initialization operation should be performed by pressing a button. During the initialization operation, the control module will actively detect whether there is fresh milk in each feeding tube 4.4 through the liquid detection sensor. If it is found that there is no fresh milk in the feeding tube 4.4, the control module controls the corresponding feeding pump 2.1 to work until there is fresh milk in the corresponding feeding tube 4.4. The purpose of the initialization operation is to ensure that when the automatic milk skin production feeding cart adds fresh milk to the milk storage tank 2 for the first time, all feeding tubes 4.4 have fresh milk, thereby ensuring the consistency of the weight of fresh milk added to the metal container 7 for the first time. Example 3

[0045] Preferably, the automatic feeding cart for milk skin production is equipped with eight feeding pumps 2.1, which are fixedly installed inside the electrical control box 3. The inlet of each feeding pump 2.1 is connected to the inside of the milk storage tank 2 through a silicone hose, and the outlet of each feeding pump 2.1 is connected to the corresponding feeding pipe 4.4 through a silicone hose. This structure, in which the feeding pumps 2.1 are installed inside the electrical control box 3, makes the appearance of the automatic feeding cart for milk skin production simpler and more aesthetically pleasing. Example 4

[0046] Furthermore, a solenoid valve is also installed on the feeding pipe 4.4. The solenoid valve is electrically connected to the drive power switch via a cable. When the solenoid valve is installed on the feeding pipe 4.4, the feeding pipe 4.4 is actually divided into two sections, which are fixedly installed at the inlet and outlet of the solenoid valve, respectively. During the operation of the automatic feeding cart for milk skin production, the solenoid valve and the feeding pump 2.1 work synchronously. That is, when the feeding pump 2.1 is working, the solenoid valve is in the conducting state, and when the feeding pump 2.1 stops working, the solenoid valve immediately turns off, thereby ensuring that the fresh milk remaining in the feeding pipe 4.4 will not drip after the feeding pump 2.1 stops working.

[0047] In the above embodiments, the feeding arm assembly 4 is hinged to the left and right side walls of the milk storage box 2; in actual need, the feeding arm assembly 4 can also be hinged to the rear side wall of the milk storage box 2, or the left and right side walls of the electrical control box 3, or the front side wall of the electrical control box 3.

[0048] It should be understood that this solution is not limited to the specific embodiments described above. Devices and structures not described in detail herein should be understood as being implemented in a manner common to the art. Any person skilled in the art can make many possible variations and modifications to this solution, or modify it into equivalent embodiments, without departing from the scope of this solution, using the methods and techniques disclosed above. This does not affect the substantive content of this solution. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this solution, without departing from its scope, still fall within the protection scope of this solution.

[0049] The parts of this utility model not described in detail are existing technologies.
