The feed port is opened and closed by a one-way valve, and the discharge port is opened and closed by a discharge ball valve. The structure is complex, the cleaning is not in place, and the volume is large. Summary of the invention

[0005] A piston cylinder having a feed inlet and a discharge outlet;

[0006] A material box connected to the feed port of the piston cylinder, the material box is used to feed material into the piston cylinder;

[0007] A non-return component, which is resettably arranged at the material outlet of the material box, and the non-return component is used to block the material outlet of the material box;

[0008] A stirring rod, which is detachably disposed in the material box and can rotate in the material box, the stirring rod is a spiral structure, and the stirring rod is used to stir the material in the material box and push the material from one end of the material box away from the material outlet to a position close to the material outlet;

[0009] A piston, which is disposed in the piston cylinder and is movable along the piston cylinder;

[0010] A water plugging nozzle is rotatably disposed in the piston cylinder, and the water plugging nozzle includes a first state in which the discharge port is closed and the feed port is opened, and a second state in which the feed port is closed and the discharge port is opened.

[0011] When the water plugging nozzle is in the first state, the piston moves away from the water plugging nozzle to form a quantitative volume cavity, and the material in the material box flows into the piston cylinder through the feed port; or, when the water plugging nozzle is in the second state, the piston moves toward the water plugging nozzle to make the material in the piston cylinder flow out through the discharge port. The present application determines the material volume by the relative position of the piston in the piston cylinder, and then realizes the suction and discharge of quantitative materials through the coordinated use of the water plugging nozzle, thereby improving work efficiency, and does not cause additional squeezing of the material, ensuring the taste of the material.

[0012] As an optional embodiment, the water plugging nozzle is in an oblate cylindrical shape, and a notch is formed on the circumference of the water plugging nozzle. When the notch is rotated to be opposite to the feed port, the water plugging nozzle is in the first state, and when the notch is rotated to be opposite to the discharge port, the water plugging nozzle is in the second state. The present application uses an oblate cylindrical water plugging nozzle to enable the water plugging nozzle to switch states more stably when rotating, and the notch design helps the material fall into the piston cylinder, thereby improving the smoothness of the material falling.

The present application uses the material guiding surface to enable the material to flow more smoothly into the piston cylinder when the water plugging nozzle is in the first state, thereby improving the material suction efficiency.

[0015] As an optional embodiment, the central angle of the arc surface is greater than the central angle of the feed port or the discharge port. The present application ensures that the feed area is maximized by adjusting the central angle of the arc surface, and the feed will not be blocked, thereby improving the working efficiency of the blanking machine.

[0017] As an optional embodiment, the feed port is provided on the top wall of the piston cylinder, and the discharge port is provided on the bottom wall of the piston cylinder opposite to the top wall, and the discharge port is located directly below the feed port. The present application makes the flow path of the material more direct by setting the feed port and the discharge port on the top wall and the bottom wall, reduces the retention of the material in the piston cylinder, and improves the efficiency of the blanking machine.

[0018] As an optional embodiment, the feed port protrudes from the outer wall of the piston cylinder, and the feed port can push the non-return assembly into the material box so that the material in the material box can fall into the piston cylinder. The non-return assembly of the present application can effectively block the discharge port of the material box, preventing the material from flowing out of the material box when it is not needed, and ensuring the directionality of the material flow and the controllability of the material dropping process.

[0019] As an optional embodiment, the non-return assembly includes a non-return valve body connected to the discharge port of the material box through a spring, and an annular sealing ring is provided on the outer peripheral wall of the non-return valve body. The present application utilizes the elastic force of the spring to ensure that the non-return valve body is promptly and accurately reset to the state of blocking the discharge port of the material box when it is not subject to external force (i.e., the top of the feed port acts), thereby ensuring the reliability of the non-return assembly in blocking the discharge port and maintaining the normal order of material flow.

[0020] As an optional embodiment, a material box motor is provided on the side of the material box away from the material outlet, and the 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 in the direction close to the material box's material outlet; the quick-release coupling includes a first shaft portion and a second shaft portion, one end of the first shaft portion is connected to the stirring rod, and a flower-shaped groove is provided on the end surface of the end, one end of the second shaft portion is connected to the output shaft of the material box motor, and a spiral elastic structure is provided between the other end of the first shaft portion and the other end of the second shaft portion, and the spiral elastic structure enables the first shaft portion to swing relative to the second shaft portion.

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

[0036] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

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

[0038] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0039] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

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

[0041] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0042] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0043] An automatic blanking machine according to an embodiment of the present application, such as Figure 1-Figure 3 As shown, it includes a piston cylinder 1, a material box 2, a piston 3 and a water shutoff nozzle 4.

[0044] The piston cylinder body 1 has a feed port 11 and a discharge port 12 . The material box 2 is connected to the feed port 11 of the piston cylinder body 1 . The material box 2 is used to supply material into the piston cylinder body 1 .

[0045] The anti-return component 9 is resettably disposed at the discharge port of the material box 2, and the anti-return component 9 is used to block the discharge port of the material box 2. That is, the anti-return component 9 can change its position under a certain external force to allow the material to pass through the discharge port, and when the external force disappears, it can return to the state of blocking the discharge port.

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

[0047] When the stirring function is activated, the stirring rod 22 starts to rotate to fully mix the materials in the material box 2. As the stirring proceeds, the stirring rod 22 gradually pushes the materials from the 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 conducive to the movement of the materials toward the material outlet of the material box 2.

[0048] The piston 3 is disposed in the piston cylinder 1 and can move along the piston cylinder 1. The water shutoff nozzle 4 is rotatably disposed in the piston cylinder 1. Figure 3 As shown, the water shutoff nozzle 4 includes a first state in which the discharge port 12 is closed and the feed port 11 is opened, and a second state in which the feed port 11 is closed and the discharge port 12 is opened.

[0049] When the water shutoff nozzle 4 is in the first state, the piston 3 moves away from the water shutoff nozzle 4 to form a quantitative volume cavity, and the material in the material box 2 flows into the piston cylinder 1 through the feed port 11; or, when the water shutoff nozzle 4 is in the second state, the piston 3 moves toward the water shutoff nozzle 4 so that the material in the piston cylinder 1 flows out through the discharge port 12.

[0050] The present application determines the material volume by the relative position of the piston 3 in the piston cylinder 1, and then realizes the suction and discharge of quantitative materials through the coordinated use of the water plugging nozzle 4, thereby improving work efficiency and causing no additional squeezing of the material, thereby ensuring the taste of the material.

[0051] The feed port 11 protrudes from the outer wall of the piston cylinder 1 , and the feed port 11 can push the anti-return component 9 into the material box 2 so that the material in the material box 2 can fall into the piston cylinder 1 .

[0052] The function of the anti-return component 9 is to block the discharge port of the material box 2 to prevent the material from flowing out at will. The feed port 11 has a specific function. When it interacts with the anti-return component 9, it can push the anti-return component 9 toward the inside of the material box 2, so that the material stored in the material box 2 can fall smoothly into the piston cylinder 1.

[0053] When the material box 2 is removed from the piston cylinder 1, the non-return assembly 9 closes the material outlet of the material box 2 to ensure that the material will not fall into the piston cylinder 1 by itself when specific conditions are not met. When the material needs to be dropped, as the material box 2 is installed on the piston cylinder 1, the feed port 11 of the piston cylinder 1 pushes up the non-return assembly 9 to open a channel for the material, so that the material can fall from the material box 2 into the piston cylinder 1, realizing a process of automatic dropping.

[0054] Through the cooperation between the feed port 11 and the non-return component 9, the non-return component 9 is automatically lifted up at the appropriate time, so that the material can fall into the piston cylinder 1 as required. There is no need for manual operation to control the falling of the material, which improves the degree of automation of the material dropping as well as the convenience and accuracy of the material dropping operation, and helps to improve the working efficiency of the entire equipment.

[0055] As an optional embodiment, Figure 6 As shown, the water shutoff nozzle 4 is in a flat cylindrical shape, and a notch 43 is formed on the circumferential side of the water shutoff nozzle 4. When the notch 43 is rotated to be opposite to the feed port 11, the water shutoff nozzle 4 is in the first state, and when the notch 43 is rotated to be opposite to the discharge port 12, the water shutoff nozzle 4 is in the second state.

[0056] In this embodiment, when the notch 43 is opposite to the feed port 11, the outer peripheral surface of the water plugging nozzle 4 blocks the discharge port 12. At this time, the feed port 11 is opened, and the material in the material box 2 can fall into the piston cylinder 1 through the feed port 11. Similarly, when the notch 43 is opposite to the discharge port 12, the outer peripheral surface of the water plugging nozzle 4 blocks the feed port 11. At this time, the discharge port 12 is opened, and the material in the piston cylinder 1 can flow out through the discharge port 12.

[0057] The present application uses a flat cylindrical water plugging nozzle 4 so that the water plugging nozzle 4 can switch states more stably when rotating. At the same time, the design of the notch 43 helps the material to fall from the material box 2 into the piston cylinder 1, thereby improving the smoothness of the material falling.

[0058] As an optional embodiment, Figure 6 As shown, the notch 43 includes 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 to the two sides of the outer circumference of the water plugging nozzle 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 plugging nozzle 4 is located. Among them, the mother circle where the water plugging nozzle 4 is located is the outer circumference circle of the oblate cylinder.

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

[0060] The present application reduces the risk of material blockage by using the first inclined surface 431 and the curved surface 432 while ensuring the blocking effect, and at the same time helps guide the material and improves the accuracy of material dropping.

[0061] As an optional embodiment, Figure 3 and Figure 5 As shown, the piston cylinder body 1 is cylindrical, and its axial direction is parallel to the horizontal direction. The water shutoff nozzle 4 is an oblate cylinder. When it is placed in the piston cylinder body 1, the axis of the water shutoff nozzle 4 is collinear with the axis of the piston cylinder body 1, that is, the axial direction of the water shutoff nozzle 4 is parallel to the horizontal direction.

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

[0063] When the water plugging nozzle 4 is in the first state, the first inclined surface 431 is inclined downward from the first end surface 41 to the direction of the second end surface 42, and the arc surface 432 is an arc surface, and the diameter of the circle where the arc surface is located gradually decreases from the first end surface 41 to the direction of the second end surface 42. When the water plugging nozzle 4 is in the second state, the first inclined surface 431 is inclined downward from the second end surface 42 to the direction of the first end surface 41, and during the rotation of the water plugging nozzle 4, the materials falling on the first inclined surface 431 and the arc surface 432 are guided to the discharge port 12.

[0064] The present application enables the material to flow down along the first inclined surface 431 and the curved surface 432 when the water shutoff nozzle 4 is in the first state, and 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, Figure 7As shown, the central angle of the arc surface 432 is greater than the central angle of the feed port 11 or the discharge port 12. The present application ensures that the feed area is maximized by adjusting the central angle of the arc surface 432, and the feed will not be blocked, thereby improving the working efficiency of the blanking machine.

[0066] In this embodiment, the centers of the circles corresponding to the arc surface 432, the feed port 11 and the discharge port 12 are on the axis of the piston cylinder 1 (i.e., the water shutoff nozzle 4), and the angle between the two side edges of the arc surface 432 is the central angle of the arc surface 432.

[0067] Lead lines are drawn from the edges of the two opposite sides of the feed port 11 / the discharge port 12 to the center of the circle where the middle of the arc surface 432 is located. At this time, the angle between the two leads is the center angle of the feed port 11 / the discharge port 12 corresponding to the circle.

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

[0069] In another embodiment, the central angle of the water plugging nozzle 4 is greater than 180 degrees, that is, the central angle of the notch 43 is less than 180 degrees. The water plugging nozzle 4 is in the third state when it rotates to simultaneously close the feed port 11 and the discharge port 12. When the automatic blanking machine is not needed, the water plugging nozzle 4 is adjusted to the third state to prevent external dust and debris from falling into the piston cylinder 1, thereby ensuring the cleanliness and hygiene of the equipment.

[0070] As an optional embodiment, Figure 3 and Figure 4 As shown, the water shutoff nozzle 4 is arranged close to one side of the piston cylinder body 1 , and the setting positions of the feed port 11 and the discharge port 12 correspond to the setting position of the water shutoff nozzle 4 .

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

[0072] A material storage chamber is formed between the side of the piston 3 away from the screw 6 and the second side wall in the piston cylinder 1, which facilitates the use of the space in the piston cylinder 1. By moving the piston 3, the material falls from the material box 2 into the material storage chamber or the material in the material storage chamber flows out.

[0073] Among them, when the material flows into the storage chamber, the piston 3 gradually moves away from the second end face 42 of the water plugging nozzle 4. When the material in the storage chamber flows out, the piston 3 gradually approaches the second end face 42 of the water plugging nozzle 4 until it is abutted against the second end face 42, so that the material in the storage chamber flows out completely.

[0074] The water shutoff nozzle 4 of the present application is disposed at a position corresponding to the feed port 11 and the discharge port 12, which facilitates the smooth flow of materials and more thorough discharge of materials, while reducing the possibility of materials being squeezed in the piston cylinder 1, thereby ensuring the taste of the materials.

[0075] As an optional embodiment, Figure 3 and Figure 4 As shown, the feed port 11 is provided on the top wall of the piston cylinder body 1 , and the discharge port 12 is provided on the bottom wall of the piston cylinder body 1 opposite to the top wall, and the discharge port 12 is located directly below the feed port 11 .

[0076] The present application defines the positions of the feed port 11 and the discharge port 12, and can utilize gravity to allow the material to flow out naturally, effectively reducing the working pressure of the piston 3. When processing semi-fluid materials, it helps to reduce the extrusion and loss of solid particles, thereby maintaining the taste and quality of the material.

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

[0078] As an optional embodiment, Figure 2 and Figure 8 As shown, a hollow motor 5 is provided outside the first side wall of the piston cylinder body 1, and a lead screw 6 is provided inside the hollow motor 5. One end of the lead screw 6 passes through the first side wall of the piston cylinder body 1 and is connected to the piston 3. When the hollow motor 5 is started, it can drive the lead screw 6 to move in a straight line along its axial direction, so that the lead screw 6 drives the piston 3 to move along the piston cylinder body 1. The moving direction of the piston 3 is along the axial direction of the piston cylinder body 1.

[0079] In this embodiment, the piston cylinder 1 is a cylindrical shape with closed ends, and its axial direction is parallel to the horizontal direction. The piston 3 is cylindrical and is arranged inside the piston cylinder 1. The axis of the piston 3 is colinear with the axis of the piston cylinder 1, that is, the axial direction of the piston 3 is parallel to the horizontal direction. Among them, the inner wall of the piston cylinder 1 is a torus surface, and the outer wall of the piston 3 is a torus surface. The two torus surfaces can contact and be movably sealed.

[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 be ensured that the amount of material fed each time is consistent. This method can be achieved by precisely controlling the hollow motor 5 and the lead screw 6, wherein the rotation and movement of the lead screw 6 drives the piston 3 to move through the connecting sleeve 7.

[0081] The present application realizes precise control of the piston 3 by using the hollow motor 5 and the lead screw 6 in combination. This driving method has a compact structure, high efficiency, and is easy to realize automatic control.

[0082] As an optional embodiment, Figure 4 As shown, 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 sealedly connected to the inner wall of the piston cylinder 1. A connecting sleeve 7 is provided in the open end of the piston 3. The other end of the lead screw 6 is rotatably connected to the connecting sleeve 7. When the lead screw 6 rotates and moves at the same time, the piston 3 is driven to move through the connecting sleeve 7.

[0083] The present application achieves a movable sealing connection between the piston 3 and the piston cylinder 1, making the piston 3 more stable during movement and avoiding material leakage. At the same time, the design of the connecting sleeve 7 enables the rotation of the screw 6 to be more effectively converted into linear movement of the piston 3, thereby improving the working efficiency and stability of the blanking machine.

[0084] like Figure 2 As shown, a control motor 8 is provided outside the second side wall of the piston cylinder body 1 opposite to the first side wall, and the output shaft of the control motor 8 passes through the second side wall of the piston cylinder body 1 and is connected to the water shutoff nozzle 4. The control motor 8 is used to drive the water shutoff nozzle 4 to rotate so that the water shutoff nozzle 4 switches between the first state and the second state.

[0085] The water plugging nozzle 4 is connected to the output shaft of the control motor 8 in a form not limited to a keyway. A support foot is provided on the bottom wall of the piston cylinder 1, and the support foot contacts the mounting surface of the automatic material preventing machine to ensure the stability of the device when in use.

[0086] As an optional embodiment, the check assembly 9 includes a check valve body 92 connected to the discharge port of the material box 2 via a spring 91 , and an annular sealing ring 93 is provided on the outer peripheral wall of the check valve body 92 .

[0087] The spring 91 plays a role of resetting. When the feed port 11 does not lift the check valve body 92, the spring 91 makes the check valve body 92 in a position to block the discharge port. The sealing ring 93 is used to enhance the sealing performance of the check valve body 92 when blocking the discharge port, and prevent the material from leaking from the gap between the valve body and the discharge port.

[0088] By utilizing the elastic force of the spring 91, it is ensured that the check valve body 92 is promptly and accurately reset to the state of blocking the discharge port when no external force is applied (i.e., the feed port 11 acts on it), thereby ensuring the reliability of the check valve 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 material box 2 better, effectively preventing material leakage.

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

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

[0091] The rotation of the stirring rod 22 can fully stir the material (such as cream) in the material box 2 to avoid agglomeration or uneven distribution of the material, thereby ensuring the consistency and stability of the material during subsequent feeding.

[0092] The design of the spiral structure with the inner diameter increasing along the direction of the discharge port can more effectively gather and push the material toward the discharge port step by step as the stirring rod 22 rotates, which helps to improve the efficiency of the material falling from the material box 2 into the piston cylinder 1, prevents the material from accumulating in the material box 2 and failing to fall smoothly, and ensures the smoothness of the material transmission link of the entire automatic blanking machine.

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

[0094] The stirring rod 22 matches the shape of the connection part of the quick release coupling 10, for example, both adopt a square structure. When the square part of the stirring rod 22 is directly placed in 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 material box 2.

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

[0096] In summary, if Figure 3 As shown, the engineering process of the automatic blanking machine is as follows:

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

[0098] When the water shutoff nozzle 4 is in the first state, the hollow motor 5 is started, and the hollow motor 5 drives the lead screw 6 to move along its axial straight line. 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 shutoff 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 material box 2 through the feed port 11. That is, under the action of gravity, the material in the material 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 hollow motor 5 is controlled to stop rotating 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 rotates and drives the water plugging nozzle 4 to rotate, so as to adjust the water plugging nozzle 4 to the second state, that is, closing the feed port 11 and opening the discharge port 12. At this time, the gap 43 is opposite to the discharge port 12.

[0101] When the water shutoff nozzle 4 is in the second state, the hollow motor 5 is started, and the hollow motor 5 drives the screw 6 to move along its axial straight line. The screw 6 moves through the connecting sleeve 7 to drive the piston 3 to move. The piston 3 starts to move toward the water shutoff nozzle 4, pushing the material in the piston cylinder 1 to move toward the discharge port 12.

[0102] The forward movement 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 a predetermined discharge amount, the hollow motor 5 is controlled to stop rotating to stop the piston 3 from advancing, thus completing the discharge process.

[0104] The application is applicable to the catering industry which needs to precisely control the inflow and outflow of materials, and other industries which need to process fluid materials or semi-fluid materials with pulp.

[0105] Furthermore, when the automatic blanking machine is finished being used, it is necessary to clean the inside thereof. At this time, the material flowing into the piston cylinder 1 is clean water, and the water plugging nozzle 4 is placed in the first state by controlling the motor 8, and the hollow motor 5 is started to make the piston 3 move back and forth repeatedly to clean the inner wall of the piston cylinder 1. After the tilting is completed, the water plugging nozzle 4 is placed in the second state by controlling the motor 8, and at this time, the hollow motor 5 drives the piston 3 to move in the direction close to the water plugging nozzle 4, so that the waste water cleaned in the piston cylinder 1 is discharged from the discharge port 12.
