TECHNICAL FIELD

[0001] The present application relates to the blanking technology field, and in particular to an automatic blanking machine. BACKGROUND

[0002] At present, most of the fluid materials with fruit flesh in the catering industry market need to be scooped with a spoon, and the material precision is controlled manually. Pumping such materials by some merchants will cause the fruit flesh to be crushed, affecting the taste of the beverage. Some merchants use plunger pumps to fill semi-fluid materials such as sauces and pastes, and the driving mode structure is complex and not easy to clean.

[0003] For example, the Chinese utility model patent with publication number CN208789965U discloses a quantitative filling device and an automatic vending machine for daily chemical products, which comprises a filling piston, a quantitative liquid material barrel and a liquid material transmission pipeline. The inlet is opened and closed by a one-way valve, and the outlet is opened and closed by a discharge ball valve. The structure is complex, cleaning is not in place, and the volume is large. SUMMARY

[0004] The purpose of the embodiment of the present application is to provide an automatic blanking machine, which comprises:

[0005] A piston cylinder having an inlet and an outlet;

[0006] A material box connected to the inlet of the piston cylinder, the material box being used to supply material to the piston cylinder;

[0007] A non-return assembly provided at the outlet of the material box and capable of being reset, the non-return assembly being used to block the outlet of the material box;

[0008] A stirring rod detachably provided in the material box and capable of rotating in the material box, the stirring rod being in a spiral structure, the stirring rod being used to stir the material in the material box and push the material from one end of the material box away from the outlet to the outlet;

[0009] A piston provided in the piston cylinder and capable of moving along the piston cylinder;

[0010] A water stop nozzle rotatably provided in the piston cylinder, the water stop nozzle comprising a first state of closing the outlet and opening the inlet and a second state of closing the inlet and opening the outlet,

[0011] When the water plug is in the first state, the piston moves away from the water plug to form a quantitative volume cavity, and the material in the cartridge flows into the piston cylinder through the feeding port; or when the water plug is in the second state, the piston moves towards the water plug to make the material in the piston cylinder flow out through the discharging port. The present application determines the material volume by the relative position of the piston in the piston cylinder, and realizes the suction and discharge of the quantitative material by the cooperation of the water plug, improves the work efficiency, and does not produce additional extrusion to the material, so as to ensure the taste of the material.

[0012] As an optional embodiment, the water plug is a flat cylinder, and a notch is formed on the periphery of the water plug. When the notch is rotated to be opposite to the feeding port, the water plug is in the first state, and when the notch is rotated to be opposite to the discharging port, the water plug is in the second state. The flat cylindrical water plug can stably switch the state when rotating, and the design of the notch helps the material to fall into the piston cylinder, improving the smoothness of the material falling.

[0013] As an optional embodiment, the notch includes two first inclined surfaces and an arc surface connecting the two first inclined surfaces, the two first inclined surfaces are respectively connected with two sides of the outer periphery of the water plug, and the diameter of the parent circle where the arc surface is located is smaller than the diameter of the parent circle where the water plug is located. The first inclined surface and the arc surface can reduce the risk of material blockage while ensuring the plugging effect, and help guide the material, improving the accuracy of the material falling.

[0014] As an optional embodiment, the water plug includes a first end surface and a second end surface opposite to the first end surface. When the water plug is in the first state, the first inclined surface is inclined downward from the first end surface to the second end surface, the arc surface is a circular arc surface, and the diameter of the circle where the circular arc surface is located gradually decreases from the first end surface to the second end surface. The material can flow more smoothly into the piston cylinder when the water plug is in the first state by the guide surface, improving the suction efficiency of the material.

[0015] As an optional embodiment, the central angle of the arc surface is greater than the central angle of the feeding port or the discharging port. By adjusting the central angle of the arc surface, the present application ensures that the feeding area is maximum and the feeding is not blocked, improving the work efficiency of the material falling machine.

[0016] As an optional embodiment, the water blocking nozzle is arranged near one side of the piston cylinder, and the feeding port and the discharging port are arranged corresponding to the water blocking nozzle.

[0017] As an optional embodiment, the feeding port is arranged on the top wall of the piston cylinder, the discharging port is arranged on the bottom wall opposite to the top wall of the piston cylinder, and the discharging port is arranged directly below the feeding port. The feeding port and the discharging port arranged on the top wall and the bottom wall make the flow path of the material more direct, reduce the residence of the material in the piston cylinder, and improve the efficiency of the dropping machine.

[0018] As an optional embodiment, the feeding port protrudes from the outer wall of the piston cylinder, and the feeding port can push the check valve body into the material box, so that the material in the material box can fall into the piston cylinder. The check valve body can effectively block the discharging port of the material box, avoid the material flowing out of the material box when it is not needed, and ensure the directionality of the material flow and the controllability of the dropping process.

[0019] As an optional embodiment, the check valve body is connected to the discharging port of the material box through a spring, and an annular sealing ring is arranged on the outer peripheral wall of the check valve body. The elastic force of the spring can ensure that the check valve body is reset to the state of blocking the discharging port of the material box in time and accurately when it is not subjected to external force (i.e., the pushing effect of the feeding port), thereby ensuring the reliability of the check valve body in blocking the discharging port and maintaining the normal order of the material flow.

[0020] As an optional embodiment, a material box motor is arranged on the side of the material box away from the discharging port, an output shaft of the material box motor is connected to the stirring rod through a quick-release coupling, and the inner diameter of the spiral structure of the stirring rod increases along the direction close to the discharging port of the material box. The quick-release coupling includes a first shaft part and a second shaft part, one end of the first shaft part is connected to the stirring rod, a flower-shaped groove is arranged on the end face of the one end, one end of the second shaft part is connected to the output shaft of the material box motor, and a spiral elastic structure is arranged between the other end of the first shaft part and the other end of the second shaft part. The spiral elastic structure enables the first shaft part to swing relative to the second shaft part. The rotation of the stirring rod can sufficiently stir the material in the material box, avoid uneven mixing of the material, and ensure that the stirring rod and the material box motor can be quickly disassembled, thereby being convenient to use.

DETAILED DESCRIPTION

[0035] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0036] It is to be understood that various alterations, modifications, and improvements can be made to the embodiments of the application herein disclosed. Accordingly, it is intended to embrace all such alterations, modifications, and improvements as fall within the scope and spirit of the application.

[0037] The accompanying drawings incorporated in and forming a part of the specification illustrate embodiments of the present application and, together with the description given above and the detailed description of the embodiments given below, serve to explain the principles of the application.

[0038] These and other characteristics of the present application will become apparent upon consideration of the following detailed description taken in conjunction with the accompanying drawings.

[0039] It should also be understood that, although the terms "first" and "second" can be used herein to describe various elements, these elements should not be limited by these terms since such elements are commonly known to one of ordinary skill in the art and can be termed in a different manner.

[0040] The above and other aspects, features, and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

[0041] Specific embodiments of the present application are described herein with reference to the accompanying drawings. However, it will be understood that the application is not limited to the particular embodiments described herein but will be understood to include any and all alternatives, modifications, and equivalents falling within the scope of the present application.

[0042] The present application can use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which can refer to one or more of the same or different embodiments of the application.

[0043] An automatic material dropping machine according to an embodiment of the present application, as shown in the accompanying drawings, comprises a piston cylinder 1, a material box 2, a piston 3 and a water stop nozzle 4. Figures 1-3 The piston cylinder 1 has a material inlet 11 and a material outlet 12, the material box 2 is connected with the material inlet 11 of the piston cylinder 1, and the material box 2 is used to supply material into the piston cylinder 1.

[0044] The piston cylinder 1 has a material inlet 11 and a material outlet 12, the material box 2 is connected with the material inlet 11 of the piston cylinder 1, and the material box 2 is used to supply material into the piston cylinder 1.

[0045] The reverse stopping assembly 9 is resettable at the material outlet of the material box 2, and the reverse stopping assembly 9 is used to block the material outlet of the material box 2. That is, the reverse stopping assembly 9 can change position under the action of external force to allow material to pass through the material outlet, and can restore to the state of blocking the material outlet when the external force disappears.

[0046] The stirring rod 22 is detachably arranged in the material box 2 and can rotate in the material box 2, the stirring rod 22 is in a spiral structure, and the stirring rod 22 is used to stir the material in the material box 2 and push the material from one end away from the material outlet of the material box 2 to the position close to the material outlet.

[0047] When the stirring function is started, the stirring rod 22 starts rotating movement, so that the material is fully mixed in the material box 2. With the stirring, the stirring rod 22 gradually pushes the material from one end away from the material outlet of the material box 2 to the position close to the material outlet of the material box 2. This is because the shape of the stirring rod 22 adopts a spiral structure, which is beneficial to the movement of the material to the material outlet of the material box 2.

[0048] The piston 3 is arranged in the piston cylinder 1 and can move along the piston cylinder 1. The water stop nozzle 4 is rotatably arranged in the piston cylinder 1, as shown in the accompanying drawings, the water stop nozzle 4 comprises a first state of closing the material outlet 12 and opening the material inlet 11 and a second state of closing the material inlet 11 and opening the material outlet 12. Figure 3

[0049] When the water stop nozzle 4 is in the first state, the piston 3 moves away from the water stop nozzle 4 to form a quantitative volume cavity, and the material in the material box 2 flows into the piston cylinder 1 through the material inlet 11; or when the water stop nozzle 4 is in the second state, the piston 3 moves close to the water stop nozzle 4 to make the material in the piston cylinder 1 flow out through the material outlet 12.

[0050] The present application determines the volume of material through the relative position of the piston 3 in the piston cylinder 1, and realizes the suction and discharge of the quantitative material through the cooperation of the water stop nozzle 4, improves the work efficiency, and does not produce additional extrusion to the material, so as to ensure the taste of the material. ​

[0051] The feeding port 11 protrudes from the outer wall of the piston cylinder 1, and the feeding port 11 can push the reverse-stopping assembly 9 into the cartridge 2, so that the material in the cartridge 2 can fall into the piston cylinder 1.

[0052] The reverse-stopping assembly 9 blocks the discharge port of the cartridge 2 to prevent the material from flowing out at will. When the reverse-stopping assembly 9 interacts with the feeding port 11, the reverse-stopping assembly 9 can be pushed into the cartridge 2, so that the material in the cartridge 2 can fall into the piston cylinder 1.

[0053] When the cartridge 2 is detached from the piston cylinder 1, the reverse-stopping assembly 9 blocks the discharge port of the cartridge 2 to prevent the material from falling into the piston cylinder 1 without meeting a specific condition. When the cartridge 2 is installed on the piston cylinder 1, the feeding port 11 of the piston cylinder 1 pushes the reverse-stopping assembly 9, opens a channel for the material, and allows the material to fall from the cartridge 2 into the piston cylinder 1, thereby realizing an automatic material falling process.

[0054] Through the cooperation of the feeding port 11 and the reverse-stopping assembly 9, the reverse-stopping assembly 9 is automatically pushed at the appropriate time, so that the material can fall into the piston cylinder 1 as required without manual operation to control the falling of the material, thereby improving the automation degree of material falling and the convenience and accuracy of material falling operation, and helping to improve the working efficiency of the entire device.

[0055] As an optional embodiment, as shown in Figure 6 The water plug 4 is in the first state when the notch 43 is opposite to the feeding port 11, and the water plug 4 is in the second state when the notch 43 is opposite to the discharge port 12.

[0056] In this embodiment, when the notch 43 is opposite to the feeding port 11, the outer peripheral surface of the water plug 4 blocks the discharge port 12, and at this time, the feeding port 11 is opened, so that the material in the cartridge 2 can fall into the piston cylinder 1 through the feeding port 11. Similarly, when the notch 43 is opposite to the discharge port 12, the outer peripheral surface of the water plug 4 blocks the feeding port 11, and at this time, the discharge port 12 is opened, so that the material in the piston cylinder 1 can flow out through the discharge port 12.

[0057] The water plug 4 in this application is in the form of a flat cylinder, which can more stably switch states when rotating, and the design of the notch 43 helps the material to fall from the cartridge 2 into the piston cylinder 1, thereby improving the smoothness of the material falling.

[0058] As an optional embodiment, as shown inFigure 6 As shown, the gap 43 comprises two first inclined surfaces 431 and an arc surface 432 connecting the two first inclined surfaces 431, the two first inclined surfaces 431 are respectively connected with two sides of the outer circumferential surface of the water plug 4, and the diameter of the mother circle where the arc surface 432 is located is smaller than the diameter of the mother circle where the water plug 4 is located. Wherein, the mother circle where the water plug 4 is located is the outer circumferential circle of the flat cylindrical shape.

[0059] In this embodiment, when the discharge port 12 is closed and the feeding port 11 is opened, the material in the material box 2 falls into the piston cylinder 1 through the feeding port 11. When feeding, the material first falls on the first inclined surface 431 and the arc surface 432, and then falls into the piston cylinder 1.

[0060] The present application reduces the risk of material blockage on the basis of ensuring the plugging effect, and helps to guide the material and improve the accuracy of material falling.

[0061] As an optional embodiment, as shown in Figure 3 and Figure 5 As shown, the piston cylinder 1 is cylindrical, and the axial direction thereof is parallel to the horizontal direction. The water plug 4 is flat cylindrical, and when it is placed in the piston cylinder 1, the axis of the water plug 4 is collinear with the axis of the piston cylinder 1, that is, the axial direction of the water plug 4 is parallel to the horizontal direction.

[0062] The water plug 4 comprises a first end surface 41 and a second end surface 42 opposite to the first end surface 41, wherein the first end surface 41 and the second end surface 42 are the two end surfaces in the axial direction of the water plug 4, and are perpendicular to the horizontal direction.

[0063] When the water plug 4 is in the first state, the first inclined surface 431 is downwardly inclined from the first end surface 41 to the second end surface 42, and the arc surface 432 is a circular arc surface, and the diameter of the circle where the circular arc surface is located gradually decreases from the first end surface 41 to the second end surface 42. When the water plug 4 is in the second state, the first inclined surface 431 is downwardly inclined from the second end surface 42 to the first end surface 41, and in the process of rotating the water plug 4, the material falling on the first inclined surface 431 and the arc surface 432 is guided to the discharge port 12.

[0064] The present application enables the material to flow along the first inclined surface 431 and the arc surface 432 when the water plug 4 is in the first state, so that the material does not accumulate and flows more smoothly into the piston cylinder 1, thereby improving the suction efficiency of the material.

[0065] As an optional embodiment, as shown in Figure 7As shown, the central angle of the arc surface 432 is greater than the central angle of the feeding port 11 or the discharging port 12. By adjusting the central angle of the arc surface 432, the feeding area is maximized and the feeding is not blocked, thereby improving the working efficiency of the automatic drop machine.

[0066] In the embodiment, the centers of the arcs corresponding to the arc surface 432, the feeding port 11 and the discharging port 12 are on the axis of the piston cylinder 1 (i.e. the water stop nozzle 4), and the included angle between the two side edges of the arc surface 432 is the central angle of the arc corresponding to the arc surface 432.

[0067] The two lines drawn from the opposite side edges of the feeding port 11 / the discharging port 12 to the center of the circle in which the middle part of the arc surface 432 is located, and the included angle between the two lines is the central angle of the arc corresponding to the feeding port 11 / the discharging port 12.

[0068] When the central angle of the arc corresponding to the arc surface 432 is greater than the central angle of the arc corresponding to the feeding port 11 / the discharging port 12, the projection of the arc surface 432 on the horizontal plane can cover the projection of the feeding port 11 or the discharging port 12 on the horizontal plane.

[0069] In another embodiment, the central angle of the water stop nozzle 4 is greater than 180 degrees, i.e. the central angle of the gap 43 is less than 180 degrees. When the water stop nozzle 4 is rotated to simultaneously close the feeding port 11 and the discharging port 12, it is in the third state. When the automatic drop machine is not needed, the water stop nozzle 4 is adjusted to the third state to prevent dust and sundries from falling into the piston cylinder 1, thereby ensuring the cleanliness of the equipment.

[0070] As an optional embodiment, as shown in Figure 3 and Figure 4 The water stop nozzle 4 is arranged close to one side of the piston cylinder 1, and the arrangement positions of the feeding port 11 and the discharging port 12 correspond to the arrangement position of the water stop nozzle 4.

[0071] In the embodiment, the arrangement position of the water stop nozzle 4 facilitates the connection of the motor 8 (to be introduced below) and the water stop nozzle 4, and the side of the water stop nozzle 4 away from the lead screw can be as close as possible to the second side wall of the piston cylinder 1.

[0072] The side of the piston 3 away from the lead screw 6 and the second side wall in the piston cylinder 1 form a storage cavity, which facilitates the use of the space in the piston cylinder 1 and the movement of the piston 3 to make the material fall into the storage cavity from the hopper 2 or make the material in the storage cavity flow out.

[0073] When the material flows into the storage cavity, the piston 3 gradually moves away from the second end surface 42 of the water stop nozzle 4, and when the material in the storage cavity flows out, the piston 3 gradually approaches the second end surface 42 of the water stop nozzle 4 until it is attached to the second end surface 42, so that the material in the storage cavity flows out completely.

[0074] The water stop nozzle 4 of the present application is arranged corresponding to the feeding port 11 and the discharging port 12, which helps the smooth flow of the material and the complete discharge of the material, and reduces the possibility of the material being squeezed in the piston cylinder 1, thereby ensuring the taste of the material.

[0075] As an optional embodiment, as shown in Figure 3 and Figure 4 The feeding port 11 is arranged on the top wall of the piston cylinder 1, and the discharging port 12 is arranged on the bottom wall of the piston cylinder 1 opposite to the top wall, and the discharging port 12 is located directly below the feeding port 11.

[0076] The present application can utilize gravity to make the material flow naturally by the position limitation of the feeding port 11 and the discharging port 12, thereby effectively reducing the working pressure of the piston 3. When processing semi-fluid material, it helps to reduce the squeezing and loss of solid particles, thereby maintaining the taste and quality of the material.

[0077] As an optional embodiment, as shown in Figure 3 The material box 2 is detachably connected with the feeding port 11. The material box 2 of the present application is detachably connected with the feeding port 11, so as to replace different material containers, which makes the replacement and cleaning of the material box 2 more convenient and improves the convenience of maintenance and operation of the equipment.

[0078] As an optional embodiment, as shown in Figure 2 and Figure 8 The hollow motor 5 is arranged outside the first side wall of the piston cylinder 1, the lead screw 6 is arranged in the hollow motor 5, one end of the lead screw 6 penetrates through the first side wall of the piston cylinder 1 and is connected with the piston 3, and the hollow motor 5 can drive the lead screw 6 to move linearly along the axial direction of the lead screw 6 when the hollow motor 5 is started, so as to drive the piston 3 to move along the piston cylinder 1. The moving direction of the piston 3 is along the axial direction of the piston cylinder 1.

[0079] In the present embodiment, the piston cylinder 1 is a cylinder with both ends closed, and the axial direction thereof is parallel to the horizontal direction. The piston 3 is a cylinder and is arranged in the piston cylinder 1, and the axis of the piston 3 is collinear with the axis of the piston cylinder 1, that is, the axial direction of the piston 3 is parallel to the horizontal direction. The inner wall of the piston cylinder 1 is a circular ring surface, the outer wall of the piston 3 is a circular ring surface, and the two circular ring surfaces can be in contact and movably and sealingly connected.

[0080] The present application can adjust the volume in the piston cylinder 1 by precisely controlling the stroke of the piston 3. The stroke of the piston 3 determines the volume of the material in the piston cylinder 1, and by limiting the maximum and minimum positions of the piston 3, it can ensure that the amount of each feeding is consistent. This method can be realized by precise control of the hollow motor 5 and the screw rod 6, wherein the rotation and movement of the screw rod 6 drives the piston 3 to move through the connecting sleeve 7.

[0081] The present application realizes the precise control of the piston 3 by the cooperation of the hollow motor 5 and the screw rod 6. This driving mode has compact structure, high efficiency, and is easy to realize automatic control.

[0082] As an optional embodiment, as shown in Figure 4 the piston 3 is a cylindrical structure with one end open and the other end closed. The outer peripheral wall of the piston 3 is movably and sealingly connected with the inner wall of the piston cylinder 1. The open end of the piston 3 is provided with a connecting sleeve 7, and the other end of the screw rod 6 is rotatably connected with the connecting sleeve 7. When the screw rod 6 rotates and moves at the same time, it drives the piston 3 to move through the connecting sleeve 7.

[0083] The present application makes the piston 3 more stable during movement through the movably and sealingly connection of the piston 3 with the piston cylinder 1, avoiding material leakage. At the same time, the design of the connecting sleeve 7 makes the rotation of the screw rod 6 more effectively converted into the linear movement of the piston 3, improving the working efficiency and stability of the material falling machine.

[0084] As shown in Figure 2 the second side wall opposite to the first side wall of the piston cylinder 1 is provided with a control motor 8. The output shaft of the control motor 8 penetrates the second side wall of the piston cylinder 1 and is connected with the water stop nozzle 4. The control motor 8 is used to drive the water stop nozzle 4 to rotate so as to switch the water stop nozzle 4 between the first state and the second state.

[0085] The water stop nozzle 4 is connected with the output shaft of the control motor 8 through a form not limited to a key groove. The bottom wall of the piston cylinder 1 is provided with a supporting leg which is in contact with the mounting surface of the automatic material falling machine to ensure the stability of the device during use.

[0086] As an optional embodiment, the non-return assembly 9 includes a non-return valve body 92 connected with the discharge port of the material box 2 through a spring 91. The outer peripheral wall of the non-return valve body 92 is provided with an annular sealing ring 93.

[0087] The spring 91 plays a role of resetting. When the feeding port 11 does not lift the non-return valve body 92, the spring 91 makes the non-return valve body 92 in the position of plugging the discharge port. The sealing ring 93 is used to enhance the sealing property of the non-return valve body 92 when plugging the discharge port, preventing the material from leaking from the gap between the valve body and the discharge port.

[0088] With the elastic force of the spring 91, the check valve body 92 can be ensured to reset to the state of blocking the discharge port in time and accurately when it is not subjected to external force (i.e. the lifting action of the feed port 11), ensuring the reliability of the check assembly 9 in blocking the discharge port and maintaining the normal order of material flow. The presence of the sealing ring 93 makes the sealing effect between the check valve body 92 and the discharge port of the cartridge 2 better, effectively preventing material leakage.

[0089] As an optional embodiment, the cartridge 2 is provided with a cartridge motor 21 on the side away from the discharge port thereof, the output shaft of the cartridge motor 21 is connected to the stirring rod 22 through the quick-release coupling 10, and the inner diameter of the spiral structure of the stirring rod 22 increases in the direction close to the discharge port of the cartridge 2.

[0090] When the cartridge motor 21 is started, it drives the stirring rod 22 to rotate. Since the stirring rod 22 has a spiral structure and the inner diameter gradually changes, it can push and guide the material in the cartridge 2 during rotation, so that the material can move in an orderly manner towards the discharge port.

[0091] The rotation of the stirring rod 22 can fully stir the material (e.g. cream) in the cartridge 2, avoiding the situation that the material is clumped or unevenly distributed, and ensuring the consistency and stability of the material during subsequent material dropping.

[0092] The design that the inner diameter of the spiral structure increases in the direction of the discharge port can more effectively gather and push the material to the discharge port as the stirring rod 22 rotates, which helps to improve the efficiency of the material falling from the cartridge 2 into the piston cylinder 1, prevents the material from accumulating in the cartridge 2 and failing to drop smoothly, and ensures the smoothness of the material transmission link of the entire automatic material dropping machine.

[0093] As an optional embodiment, as shown in Figures 9-10 the stirring rod 22 is connected to one end of the quick-release coupling 10, the other end of the quick-release coupling 10 is connected to the output shaft of the cartridge motor 21, and the output shaft of the cartridge motor 21 drives the stirring rod 22 to rotate through the quick-release coupling 10.

[0094] The connection part of the stirring rod 22 and the quick-release coupling 10 are matched in shape, for example, both adopt a square structure. When the square part of the stirring rod 22 is directly put into the groove part of the quick-release coupling 10, the feed port 11 of the piston cylinder 1 is inserted into the discharge port of the cartridge 2.

[0095] The quick release coupling 10 comprises a first shaft part 101 and a second shaft part 102, wherein the first shaft part 101 is connected with the stirring rod 22, the end face of one end of the first shaft part 101 is provided with a patterned groove 104 and is chamfered at the edge, one end of the second shaft part 102 is connected with the output shaft of the box motor 21, and the other end of the first shaft part 101 is connected with the other end of the second shaft part 102, and a spiral elastic structure 103 is arranged between the other end of the first shaft part 101 and the other end of the second shaft part 102, so that the first shaft part 101 can swing slightly relative to the second shaft part 102, that is, the patterned groove 104 can swing slightly, and therefore the square part of the stirring rod 22 can be inserted into the quick release coupling 10 at any position.

[0096] In summary, as shown in the figure, the engineering process of the automatic material dropping machine is as follows: Figure 3

[0097] When feeding, the control motor 8 is started, the output shaft of the control motor 8 is rotated and drives the water stop nozzle 4 to rotate, so as to adjust the water stop nozzle 4 to the first state, that is, to close the discharge port 12 and open the feeding port 11, and at this time the gap 43 is opposite to the feeding port 11.

[0098] When the water stop nozzle 4 is in the first state, the hollow motor 5 is started, the hollow motor 5 drives the lead screw 6 to move linearly along the axial direction, the lead screw 6 moves through the connecting sleeve 7 to drive the piston 3 to move, and the piston 3 starts to move away from the water stop nozzle 4.

[0099] The retreat of the piston 3 forms a quantitative cavity in the piston cylinder 1, and the material is sucked into the box 2 through the feeding port 11. That is, under the action of gravity, the material in the box 2 is sucked into the piston cylinder 1 until the piston 3 moves to the preset position. When the piston 3 reaches the preset position, the control hollow motor 5 is stopped to stop the retreat of the piston 3, and the feeding process is completed.

[0100] When discharging, the control motor 8 is started, the output shaft of the control motor 8 is rotated and drives the water stop nozzle 4 to rotate, so as to adjust the water stop nozzle 4 to the second state, that is, to close the feeding port 11 and open the discharge port 12, and at this time the gap 43 is opposite to the discharge port 12.

[0101] When the water stop nozzle 4 is in the second state, the hollow motor 5 is started, the hollow motor 5 drives the lead screw 6 to move linearly along the axial direction, the lead screw 6 moves through the connecting sleeve 7 to drive the piston 3 to move, and the piston 3 starts to move close to the water stop nozzle 4, and pushes the material in the piston cylinder 1 to move to the direction of the discharge port 12.

[0102] The advance of the piston 3 pushes the material out of the piston cylinder 1 and flows out through the discharge port 12. This process can be continuous or on-demand. By controlling the moving distance of the piston 3, the discharge amount can be accurately controlled to ensure the consistency of each discharge.

[0103] ​When the material is completely discharged or reaches the predetermined discharge amount, the hollow motor 5 is controlled to stop rotating, so as to stop the advance of the piston 3, and the discharging process is completed.

[0104] The present application is suitable for the catering industry which needs to precisely control the material in and out, and other industries which need to process fluid material or semi-fluid material with pulp.

[0105] Moreover, when the automatic material discharging machine is used, the inside thereof needs to be cleaned. At this time, the material flowing into the piston cylinder 1 is clean water, the water blocking nozzle 4 is controlled to be in the first state by the control motor 8, and the hollow motor 5 is started to make the piston 3 repeatedly move back and forth, so as to clean the inner wall of the piston cylinder 1. After the tilting is completed, the water blocking nozzle 4 is controlled to be in the second state by the control motor 8, at this time, the piston 3 is driven by the hollow motor 5 to move towards the water blocking nozzle 4, so as to make the clean water in the piston cylinder 1 after cleaning be discharged from the discharging port 12.

[0106] The above embodiments are only exemplary embodiments of the present application, and are not used to limit the present application, the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and the modification or equivalent replacement is also regarded as falling within the protection scope of the present application.
