Description

Technical Field

[0001] This application relates to the field of filling equipment technology, specifically to an ice cream filling device and control method. Background Technology

[0002] In the frozen dessert industry, the combination of chocolate and ice cream filling is a classic and widely loved by consumers. Currently, the mixing of chocolate and ice cream filling is usually shaped using ice cream filling equipment. This equipment has a nozzle with channels for injecting chocolate and ice cream filling, and the ice cream product is shaped by controlling the rotation of the nozzle. However, nozzle rotation often leads to leakage problems, and the resulting product forms are relatively limited.

[0003] Therefore, overcoming at least one of the above-mentioned defects is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide an ice cream filling device and control method with a low probability of leakage.

[0005] Ice cream filling equipment, characterized in that it includes:

[0006] The filling body includes a first feed channel and a second feed channel that are relatively isolated from each other. The lower end of the filling body has a first outlet that communicates with the first feed channel and a second outlet that communicates with the second feed channel.

[0007] A first drive component is used to drive the infusion body to reciprocate along an axial direction, wherein the axial direction is the length direction of the infusion body;

[0008] The second driving component is used to drive the infusion body to perform periodic translational motion along a preset trajectory in a first plane, wherein the first plane is a plane perpendicular to the axis.

[0009] Compared to the prior art where the nozzle rotates relative to its mounted main body, this embodiment of the application is provided with a second driving component. The second driving component can drive the filling body to perform periodic translational motion in a plane perpendicular to the axial direction according to a preset trajectory. During the translational motion of the filling body, ice cream milk and chocolate are injected into the container from the first and second discharge ports, respectively. The first driving component controls the position of the filling body along the axial direction to fill the container. In this embodiment, it is not necessary to set the filling body as two rotating parts, which reduces the probability of leakage. Furthermore, in this embodiment, different preset trajectories result in different patterns of ice cream milk and chocolate being injected into the container, thereby meeting the needs of producing different products.

[0010] In one example, within each cycle or in adjacent cycles, the discharge trajectory of the first discharge port can cover the discharge trajectory of the second discharge port.

[0011] In one example, the second drive assembly includes an eccentric mechanism comprising an eccentrically positioned first shaft and a second shaft extending along the axial direction. The infusion body is connected to the second shaft. When the second drive assembly drives the first shaft to rotate, the second shaft rotates around the first shaft and causes the infusion body to perform a circular motion in the first plane.

[0012] In one example, a fixing plate is also included, on which at least one of the infusion bodies is mounted, the fixing plate being connected to the output end of the second shaft, and the first drive assembly driving all the infusion bodies to reciprocate axially via the fixing plate;

[0013] Alternatively and / or, the eccentricity of the first and second shafts ranges from 4 mm to 5.5 mm, and the outer diameter of the lower end of the infusion body ranges from 45 mm to 60 mm.

[0014] In one example, there are two eccentric mechanisms, located at both ends of the fixed plate, and the power output shaft of the second drive assembly is connected to the first shaft of one of the two eccentric mechanisms.

[0015] Alternatively / and, the fixed plate is connected to the output end of the second shaft via a second bearing.

[0016] In one example, the projections of the second axis and the axial direction of each of the infusion bodies onto the first plane are on the same straight line.

[0017] In one example, the first outlet is an elongated structure that extends outward from the center of the lower end face of the injection body. The length of the second outlet is less than the length of the first outlet, and the radial dimension of the outer edge of the second outlet is not greater than the radial dimension of the outer edge of the elongated structure.

[0018] In one example, the number of first discharge ports includes at least two, and each of the first discharge ports is evenly arranged circumferentially, with at least one second discharge port between adjacent first discharge ports;

[0019] Alternatively / and, the second discharge port is circular or elliptical, the first discharge port is arc-shaped, all of the arcs have the same length and the same bending direction, and there is one or more second discharge ports between adjacent first discharge ports.

[0020] In one example, the injection body includes a valve body and a valve stem. Along the axial direction, the valve body has a first segment and a second segment connected or integrally formed. The first segment has a first cavity. The valve stem has a sealing portion that reciprocates within the first cavity. The first segment has a second cavity. The first feed channel includes the second cavity and at least a portion of the first cavity. The first segment has a first feed port communicating with the first cavity. The first discharge port and the second discharge port are both located at the bottom of the second segment.

[0021] The first cavity has a first orifice and a second orifice, the first orifice being located below the second orifice, and the first feed inlet being located above the second orifice;

[0022] When the sealing part is located in the first hole section, the material in the first feed port can flow to the first discharge port through the gap between the first cavity and the valve stem and the second cavity; when the sealing part is located in the second hole section, the sealing part cooperates with the peripheral wall of the second hole section to isolate the second hole section.

[0023] In one example, the second feed channel is disposed in the second segment, and the number of the second feed channels includes one or more. The outer wall of the second segment has an annular feed port, and the upper end of each second feed channel is connected to the annular feed port. The bottom of the second segment has a second discharge port corresponding to the second feed channel.

[0024] This application also provides a control method for the filling process of the above-mentioned ice cream filling equipment, the control method comprising:

[0025] The first driving component drives the injection body to the lowest axial position, injects the first material into the first feed channel, injects the second material into the second feed channel, and simultaneously controls the second driving component to drive the injection body to translate along a preset trajectory in the first plane.

[0026] During the translation process of the filling body, the first driving component gradually raises the height of the filling body at a first speed. When the filling body is at a predetermined height, the injection of the second material into the second feed channel is stopped, and the translation of the filling body is stopped. After the filling body stops translating for a predetermined time, the injection of the first material into the first feed channel is stopped, and the upward movement of the filling body is stopped.

[0027] In one example, after the infusion body stops at a predetermined height for a predetermined time, the first drive component drives the infusion body to rise to the highest position at a second speed, wherein the second speed is greater than the first speed.

[0028] In one example, the injection body includes a valve body and a valve stem. Along the axial direction, the valve body has a first segment and a second segment connected or integrally formed. The first segment has a first cavity. The valve stem has a sealing portion that reciprocates within the first cavity. The first segment has a second cavity. The first feed channel includes the second cavity and at least a portion of the first cavity. The first segment has a first feed port communicating with the first cavity. The first discharge port and the second discharge port are both located at the bottom of the second segment.

[0029] The first cavity has a first orifice and a second orifice, the first orifice being located below the second orifice, and the first feed inlet being located above the second orifice;

[0030] When the sealing part is located in the first hole section, the material in the first inlet can flow to the first outlet through the gap between the first cavity and the valve stem and the second cavity; when the sealing part is located in the second hole section, the sealing part cooperates with the peripheral wall of the second hole section to isolate the second hole section;

[0031] During the process of injecting the first material into the first feed channel, the sealing part is controlled to be located in the first hole section;

[0032] While stopping the injection of the first material into the first feed channel, the following steps are also performed: moving the sealing part from the first orifice to the second orifice to draw back the first material located in the orifice below the sealing part.

[0033] In one example, the ice cream filling device includes an eccentric mechanism comprising an eccentrically positioned first shaft and a second shaft extending along the axial direction, and the filling body being connected to the second shaft;

[0034] The control method specifically involves controlling the second driving component to drive the infusion body to translate within the first plane. The second driving component drives the first shaft of the eccentric mechanism to rotate, and the second shaft rotates around the first shaft, thereby causing the infusion body to perform circular motion within the first plane.

[0035] In one example, the first outlet is a long strip structure that extends outward from the center of the lower end face of the injection body, the length of the second outlet is less than the length of the first outlet, and the radial dimension of the outer edge of the second outlet is not greater than the radial dimension of the outer edge of the strip structure.

[0036] Alternatively / and, the second discharge port is circular or elliptical, the first discharge port is arc-shaped, all of the arcs have the same length and the same bending direction, and there is one or more second discharge ports between adjacent first discharge ports.

[0037] In one example, the first material is ice cream milk with a temperature range of -2.5 degrees to -3.5 degrees, and the second material is chocolate with a temperature range of 35 degrees to 45 degrees. Attached Figure Description

[0050] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Please refer to Figures 1 to 10 , Figure 1 This is a cross-sectional schematic diagram of the ice cream filling equipment in the embodiments of this application; Figure 2 for Figure 1 A cross-sectional schematic diagram of the injection body in the structure shown; Figure 3 for Figure 2 The diagram shows the structure of the first segment in the injection body; Figure 4 for Figure 2 A bottom view of the second segment of the injection body shown; Figure 5 for Figure 4 CC section view shown in the second segment; Figure 6 for Figure 1 A cross-sectional view of the structure shown in Figure BB; Figure 7 for Figure 2 The diagram shows the relative positions of the second segment and the container at four moments during the translational motion of the injection body.

[0052] This application provides an ice cream filling device, which can also be used for filling cups with two or more materials. Of course, it is not excluded that the ice cream filling device of this application can be used for filling cups with only one material. This article takes the example of an ice cream filling device that can simultaneously fill cups with two materials, namely chocolate 300 and ice cream milk 200, to introduce the technical solution and technical effects.

[0053] In this embodiment of the application, the ice cream filling equipment includes a frame 1, which can be an integral unit or a separate unit. The main function of the frame 1 is to provide an installation base for other components of the ice cream filling equipment.

[0054] The ice cream filling equipment also includes a filling body 2, a first drive assembly, and a second drive assembly. The filling body 2 can be installed on the frame 1, and the first drive assembly and the second drive assembly can be wholly or partially installed on the frame 1.

[0055] In this embodiment, the filling body 2 includes a first feed channel 2-1 and a second feed channel 2-2 that are relatively isolated from each other. The lower end of the filling body 2 also includes a first outlet 2-1b and a second outlet 2-2b. The first outlet 2-1b is connected to the first feed channel 2-1, and the second outlet 2-2b is connected to the second feed channel 2-2. In this application, the first feed channel 2-1 is the feed channel for ice cream milk 200, and the second feed channel 2-2 is the feed channel for chocolate 300. The first feed channel 2-1 forms a first inlet 2-1a on the outer wall of the filling body 2, and the first inlet 2-1a is connected to an external ice cream milk pipe. The second feed channel 2-2 forms a second inlet 2-2a on the outer wall of the filling body 2, and the second inlet 2-2a is connected to an external chocolate pipe. In this way, the ice cream milk 200 in the external ice cream milk pipe 8 flows along the first feed channel 2-1 and flows out from the first outlet 2-1b to the container 100 below the filling body 2. Similarly, the chocolate 300 in the chocolate pipe 9 flows from the second feed port 2-2a to the second feed channel 2-2, flows along the second feed channel 2-2 to the second outlet 2-2b, and flows out from the second outlet 2-2b into the container 100 below the filling body 2.

[0056] Typically, both the ice cream milk pipe 8 and the chocolate pipe 9 are equipped with on / off valves to meet the filling requirements. In addition, the shape of the container 100 below the filling body 2 is mainly determined by the product shape. The container 100 can be a conical structure (e.g., a cone or a polygonal pyramid), a frustum shape (e.g., a frustum or a prism), a columnar structure (e.g., a cylinder or a prism), or a cube, etc.

[0057] In this embodiment, the first drive assembly is used to drive the infusion body 2 to reciprocate along the axial direction. Specifically, the first drive assembly can drive the infusion body 2 to reciprocate relative to the frame 1 along the axial direction. The axial direction is approximately the length direction of the infusion body 2. The first drive assembly can be a cylinder, a motor-screw assembly, etc.

[0058] In this embodiment, the second driving component drives the filling body 2 to perform periodic translational motion on a first plane, which is perpendicular to the axial direction. That is, the trajectory of the translational motion of the filling body 2 can be determined according to the shape of the container 100. For a circular opening of the container 100, the trajectory is approximately circular; for an elliptical opening, the trajectory is approximately elliptical; and for a rectangular opening, the trajectory is approximately rectangular. The determination of the translational trajectory (preset trajectory) of the filling body 2 is mainly based on the shape of the container 100, the position of the first outlet 2-1b, and the second outlet 2-2b, with the goal of effectively filling the container 100 and mixing different patterns of the ice cream milk 200 and chocolate 300. In this embodiment, the container 100 has a frustum-shaped structure, and the translational motion trajectory of the filling body 2 is approximately circular.

[0059] Compared with the prior art where the nozzle rotates relative to the main body on which it is installed, this embodiment of the application is provided with a second driving component. The second driving component can drive the filling body 2 to make periodic translational motion in a plane perpendicular to the axial direction according to a preset trajectory. During the translational motion of the filling body 2, ice cream milk 200 and chocolate 300 are injected into the container 100 from the first outlet 2-1b and the second outlet 2-2b, respectively. The first driving component controls the position of the filling body 2 along the axial direction to fill the container 100. In this embodiment, it is not necessary to set the filling body 2 as two rotating parts, which reduces the probability of leakage. Furthermore, in this embodiment of the application, the preset trajectory is different, and the patterns presented by the two materials, ice cream milk 200 and chocolate 300, injected into the container 100 are also different, thereby meeting the needs of producing different products.

[0060] The key structural parameters of the materials and equipment during the filling process are fundamental to the realization of this technology. High temperatures in the chocolate 300 channel prevent blockage in the second feed channel 2-2 (chocolate 300 channel), but this slows down the solidification of the chocolate 300, resulting in thinner chocolate pieces. Simultaneously, the compression from the ice cream milk 200 causes the chocolate 300 to be less concentrated in the center of the cup and more concentrated around the edges. Conversely, low temperatures in the chocolate 300 channel make it prone to blockage, causing production discontinuity, but also result in slower solidification and thicker chocolate pieces. Maintaining the chocolate 300 temperature between 35 and 45 degrees Celsius ensures stable production, uniform distribution of the chocolate 300, and a moderate thickness for the chocolate pieces. At a higher temperature (200), the product's formation is unstable, but the container (100) will not be empty around the edges. The ice cream milk 200 exerts less pressure on the chocolate 300, making the chocolate 300 thicker. At a lower temperature, the product's formation is stable, but it is easy for the cup to become empty around the edges. The milk exerts greater pressure on the chocolate 300, making the chocolate 300 thinner. The ice cream milk 200 temperature should be controlled between -2.5 and -3.5 degrees Celsius to meet the requirements for cup fullness and formation stability.

[0061] Specifically, this application also provides a control method for the above-mentioned ice cream filling equipment, the control method including:

[0062] The first drive assembly drives the filling body 2 to the lowest axial position, injects the first material into the first feed channel 2-1, and injects the second material into the second feed channel 2-2. At the same time, it controls the second drive assembly to drive the filling body 2 to perform translational motion along a preset trajectory in the first plane; that is, the filling operation begins.

[0063] During the translation process of the filling body 2, the first drive component gradually raises the height of the filling body 2 at a first speed. When the filling body 2 is at a predetermined height, it stops injecting the second material into the second feed channel 2-2 and stops the translation of the filling body 2. After the filling body 2 stops translating for a predetermined time, it stops injecting the first material into the first feed channel 2-1 and stops moving upward.

[0064] The ice cream milk 200 inlet pipe and the chocolate 300 inlet pipe connected to the filling body 2 are usually equipped with ice cream milk 200 valve and chocolate 300 valve. By controlling the opening and closing of the ice cream milk 200 valve, the injection of ice cream milk 200 into the first inlet channel 2-1 can be stopped or allowed. Similarly, by controlling the opening and closing of the chocolate 300 valve, the injection of chocolate 300 into the second inlet channel 2-2 can be stopped or allowed.

[0065] In this control method, the ice cream milk 200 and chocolate 300 are not closed at the same time. Chocolate 300 is closed first, and then the ice cream milk 200 is closed. That is, the ice cream milk 200 is closed later than the chocolate 300, and also later than the translational stop of the filling body 2. This will prevent the problem of disordered patterns in the middle of the product shape.

[0066] In this embodiment of the application, the control method further includes: after the pouring body 2 stops at a predetermined height for a predetermined time, the first driving component drives the pouring body 2 to move upward to the highest position at a second speed, wherein the second speed is greater than the first speed. This avoids dripping material from affecting the surface shape of the product and helps to improve production efficiency.

[0067] In this embodiment, within each cycle, the discharge trajectory of the first discharge port 2-1b covers the discharge trajectory of the second discharge port 2-2b. Thus, within each cycle, the ice cream milk 200 flowing out of the first discharge port 2-1b can cover the chocolate 300 flowing out of the second discharge port 2-2b. The ice cream milk 200 and the chocolate 300 can create a superposition effect. The squeezing action of the ice cream milk 200 on the chocolate 300 helps to achieve a uniform sheet distribution of the chocolate 300 in the ice cream milk 200. This results in the product having uniformly distributed sheet chocolate 300 on both the cross-section and longitudinal section, allowing consumers to experience the smooth texture of sheet chocolate 300 in every bite.

[0068] The second drive assembly includes an eccentric mechanism 3, which comprises an eccentrically positioned first shaft 31 and a second shaft 32, both extending axially. The center lines S1 of the first shaft 31 and S2 of the second shaft 32 are staggered. The first shaft 31 is a power input shaft, connected to the power output shaft 5 of the second drive assembly, i.e., the second drive assembly is connected to the first shaft 31 to transmit power from the second drive assembly to the first shaft 31. The second shaft 32 is directly or indirectly connected to the injection body 2. This application embodiment shows a specific implementation in which the second shaft 32 is indirectly connected to the injection body 2 via a fixing plate 4. The first shaft 31 can be rotatably mounted on the frame 1 via a first bearing 33.

[0069] In this embodiment, the filling body 2 is connected to the second shaft 32. When the first shaft 31 is driven to rotate, the second shaft 32 will move in a circle around the first shaft 31. At the same time, the filling body 2 will also perform a circular translation with the distance (eccentricity value) between the first shaft 31 and the second shaft 32 as the radius. In one embodiment, after installation, the central axis of the filling body and the central axis of its corresponding container installation station are eccentrically set, and the eccentricity value is equal to the eccentricity value of the first shaft and the second shaft. Figure 7The figure shows the relative positional relationship between the lower end of the infusion body 2 and the container 100 at four times (T1, T2, T3, T4) during one translation cycle of the infusion body 2. In the figure, M1 is the center of the container 100, and M2 is the central axis of the infusion body 2. In the installed state, the lower end of the infusion body 2 is also eccentric to the center of the container 100, and the distance L between them is equal to the eccentricity value between the first axis 31 and the second axis 32.

[0070] To better understand the circular translation, the first discharge ports 2-1b of the injection body 2 are indicated by different labels. The six first discharge ports 2-1b are: 2-1b1, 2-1b2, 2-1b3, 2-1b4, 2-1b5, and 2-1b6. As can be seen from the four figures, the relative positions of the six first discharge ports 2-1b remain unchanged during the translation of the injection body 2.

[0071] In this embodiment, the translational motion is achieved through the eccentric mechanism 3. The magnitude of the eccentricity is crucial to product forming, equipment stability, and production speed. A larger eccentricity results in a more uniform distribution of chocolate 300 and ice cream milk 200, but also greater vibration, poorer equipment stability, and slower production speed. Conversely, a smaller eccentricity results in a less uniform distribution of chocolate 300 and ice cream milk 200, but less vibration, better equipment stability, and faster production speed. Furthermore, the eccentricity is also influenced by the inner diameter of the product container 100 and the structure and outer diameter of the lower end of the filling body 2. With an inner diameter of approximately 85 mm and an outer diameter of approximately 55 mm at the lower end of the filling body 2, an eccentricity of 5.5 mm to 4 mm ensures uniform distribution of chocolate 300 and ice cream, stable equipment operation, and a production speed that meets industrial requirements.

[0072] In this embodiment, at least one injection body 2 is mounted on the fixed plate 4. The fixed plate 4 is connected to the output end of the second shaft 32. The first drive assembly drives all the injection bodies 2 to reciprocate axially through the fixed plate 4. The figure shows a specific example where four injection bodies 2 are mounted on the fixed plate 4 simultaneously. Of course, the number of injection bodies 2 mounted on the fixed plate 4 is not limited to that shown herein; it can be two, three, five, or more, etc. Specifically, the output end of the second shaft 32 of the eccentric mechanism 3 and the fixed plate 4 can be connected through the second bearing 34. In this way, the second shaft 32 and the fixed plate 4 can rotate relative to each other in the circumferential direction, which can effectively avoid jamming when the second shaft 32 drives the fixed plate 4 to move, and improve the smoothness of the mechanism's movement.

[0073] In this embodiment, an eccentric mechanism 3 can simultaneously drive the action of two or more filling bodies 2 to achieve simultaneous filling of two or more containers 100, resulting in high production efficiency.

[0074] In this embodiment, there are two eccentric mechanisms 3, located at both ends of the fixed plate 4. The power output shaft of the second drive assembly is connected to the first shaft 31 of one of the two eccentric mechanisms 3. In this embodiment, both ends of the fixed plate 4 are connected to the eccentric mechanisms 3. The two eccentric structures can provide stable support for the fixed plate 4. The first shaft 31 of one of the two eccentric mechanisms 3 is connected to the second drive assembly, and the other is a driven member. In this way, the fixed plate 4 can be driven to perform circular translation using only one drive assembly, and the structure is relatively simple.

[0075] Please refer to Figure 6 In this embodiment, the projections of the second axis 32 and the axial directions of each of the filling bodies 2 in the first plane are located on the same straight line S3. This can minimize the vibration caused by eccentric operation, improve the stability of the workstation operation, ensure the structural stability of the filling product, and at the same time ensure that the amount of vibration in the high-speed production station is small, which can improve the production speed of the product and make the workstation meet the requirements of industrial production of the product.

[0076] In this embodiment, the first outlet 2-1b is an elongated structure extending outward from the center of the lower end face of the filling body 2. The length of the second outlet 2-2b is less than the length of the first outlet 2-1b, and the radial dimension of the outer edge of the second outlet 2-2b is not greater than the radial dimension of the outer edge of the elongated structure. Figure 4 As shown, the maximum radius of the projection of the second outlet 2-2b in the plane perpendicular to the axial direction is smaller than the maximum radius of the projection of the first outlet 2-1b in the plane perpendicular to the axial direction. Thus, during translation, the ice cream milk 200 from the first outlet 2-1b can envelop the chocolate 300 from the second outlet 2-2b, restricting the outward diffusion of the chocolate 300 and creating a wrapping effect.

[0077] In one embodiment, the number of first outlets 2-1b includes at least two, and each first outlet 2-1b is evenly arranged circumferentially, with at least one second outlet 2-2b between adjacent first outlets 2-1b; this ensures the uniform distribution of chocolate 300 in the ice cream base 200 during product production. Considering the fluidity of chocolate 300, there will also be chunks of chocolate 300 near the cup wall, so consumers can not only experience the smooth texture of each piece of chocolate 300, but also occasionally enjoy the surprise of chunks of chocolate 300.

[0078] In one embodiment, the second discharge port 2-2b is circular or elliptical, and the first discharge port 2-1b is arc-shaped. All arcs have the same length and bend in the same direction. There are one or more second discharge ports 2-2b between adjacent first discharge ports 2-1b. The arc-shaped structure makes the chocolate 300 pattern on the product surface vivid and dynamic.

[0079] In the above control method, controlling the second drive component to drive the injection body 2 to translate in the first plane is specifically as follows: the second drive component drives the first shaft 31 of the eccentric mechanism 3 to rotate, the second shaft 32 rotates around the first shaft 31, and drives the injection body 2 to make circular motion in the first plane. The circular motion structure is relatively simple.

[0080] Furthermore, the combination of the arc shape of the first discharge port 2-1b and the structure of the second discharge port 2-2b facilitates the formation of dynamic patterns on the product surface. The center of the product surface is essentially devoid of chocolate 300. Please refer to [the relevant documentation / reference]. Figure 10 The surface pattern of the product shown.

[0081] In this embodiment of the application, the injection body 2 includes a valve body 21 and a valve stem 22. Along the axial direction, the valve body 21 has a first segment 211 and a second segment 212 that are connected or integrally formed. The first segment 211 has a first cavity 211a. The valve stem 22 has a sealing part 221 that reciprocates in the first cavity 211a. The first segment 211 has a second cavity 212a. The first feed channel 2-1 includes the second cavity 212a and at least a portion of the first cavity 211a. The first segment 211 has a first feed port 2-1a that communicates with the first cavity 211a. The first discharge port 2-1b and the second discharge port 2-2b are both located at the bottom of the second segment 212.

[0082] The first cavity 211a has a first hole section 2111 and a second hole section 2112. The first hole section 2111 is located below the second hole section 2112, and the first feed port 2-1a is located above the second hole section 2112.

[0083] When the sealing part 221 is located in the first hole section 2111, the material in the first feed port 2-1a can flow along the gap between the first cavity 211a and the valve stem 22 and the second cavity 212a to the first discharge port 2-1b; when the sealing part 221 is located in the second hole section 2112, the sealing part 221 cooperates with the peripheral wall of the second hole section 2112 to isolate the second hole section 2112.

[0084] The filling body 2 can be in a normally closed state. When the valve stem 22 is in the upper position, the sealing part 221 is located in the second hole section 2112, and the two cooperate to close the first chamber 211a. When the valve stem 22 is in the lower position, the sealing part 221 is located in the first hole section 2111. There is a gap between the sealing part 221 and the first hole section 2111, and the ice cream milk 200 can flow from the first inlet 2-1a to the first outlet 2-1b. When the sealing part 221 moves from the first hole section 2111 to the second hole section 2112, it can not only close the first chamber 211a, but also generate a suction effect.

[0085] A sealing ring 222 may be further provided on the sealing part 222 to improve the sealing performance between it and the second hole section 2112.

[0086] To improve the stability of the axial movement of the valve stem 22, the valve stem also has a guide shaft section 223 at the end away from the sealing part 222, and the first cavity 211a is provided with a third hole section 2113, and the guide shaft section 223 and the third hole section 2113 are circumferentially guided and cooperated.

[0087] Specifically, in the above control method, during the process of injecting the first material into the first feed channel 2-1, the sealing part 221 is located in the first hole section 2111, so that the first material can flow along the first feed channel 2-1 to the first discharge port 2-1b.

[0088] While stopping the injection of the first material into the first feed channel 2-1 in the above control method, the following steps are also performed: the sealing part 221 is moved from the first hole section 2111 to the second hole section 2112 to draw back the first material located in the hole section below the sealing part 221. The movement of the sealing part 221 is achieved by a third drive assembly, which can be a cylinder, a motor-screw assembly, or other components capable of moving the component up and down. This application provides an example where the third drive assembly is a cylinder, with the telescopic rod 6 of the cylinder extending into the first cavity 211a to connect the valve stem 22. The telescopic rod 6 and the valve stem 22 can be connected by screws or other components.

[0089] In this embodiment, when the sealing part 221 moves from the second hole section 2112 to the first hole section 2111, it can generate suction to draw the ice cream milk 200 located below the sealing part 221 back into the first cavity 211a, thereby eliminating the influence of the residual pressure of the ice cream milk 200 in the second section 212 on the product pattern, and making the material breakage more thorough, so that the pattern on the product surface is complete and the molding is stable.

[0090] In this embodiment, a second feed channel 2-2 is disposed on a second segment 212. The number of second feed channels 2-2 includes one or more. The outer wall of the second segment 212 has an annular feed inlet. The upper end of each second feed channel 2-2 is connected to the annular feed inlet, and the bottom of the second segment 212 has a second discharge outlet 2-2b corresponding to the second feed channel 2-2. Specifically, the second segment 212 includes a nozzle body 2121 and a sleeve 2122. The nozzle body 2121 and the sleeve 2122 can be closed to form an annular feed inlet (second feed inlet 2-2a). The second feed channel 2-2 is disposed on the nozzle body 2121. The second discharge outlet 2-2b is disposed at the lower end of the nozzle body 2121. The lower end of the nozzle body 2121 can be hemispherical or other shapes.

[0091] In this embodiment, the second feed channel 2-2 is processed in the second segment 212, shortening the length of the second feed channel 2-2, minimizing temperature loss during the flow of chocolate 300, avoiding the occurrence of chocolate 300 clogging the channel, and the annular feed port facilitates connection with external pipelines, and chocolate 300 can flow into the second feed channel 2-2 quickly and evenly.

[0092] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
