[0042] The following will be described in combination with Figures 1 to 3 The discharge device of the embodiment of the present application is described, which can be installed at the discharge port position of the feeding device (for example, freezing equipment) and communicated to the next station (for example, product forming station). Figure 1 The arrow A in the figure indicates the direction of the feed liquid entering when the feeding device feeds, and the arrow B indicates the direction of the feed liquid flowing out when the feeding device feeds; Figure 2 The arrow C in the figure indicates the direction of the air supply when the excess material is discharged, and the arrow D indicates the direction of the feed liquid flow when the excess material is discharged.

[0043] In combination with Figure 1 And Figure 2 According to the discharge device of the embodiment of the present application, the discharge device comprises a three-way seat block 100, a sealing sleeve 200, a sealing driving member 400 and a top block 300.

[0044] The three-way seat block 100 is provided with a first connecting hole 110 and a second connecting hole 120, and the first connecting hole 110 and the second connecting hole 120 are arranged at an angle, preferably, the first connecting hole 110 and the second connecting hole 120 are perpendicular to each other. The middle parts of the first connecting hole 110 and the second connecting hole 120 are communicated. Among them, one end of the first connecting hole 110 away from the second connecting hole 120 is adapted to connect the discharge port of the feeding device, and the feed liquid supplied by the feeding device can enter the second connecting hole 120 through the first connecting hole 110. One end of the second connecting hole 120 is adapted to be connected to the next station, so as to guide the feed liquid into the next station.

[0045] The blocking sleeve 200 is a cylindrical tube structure, and the blocking sleeve 200 is internally provided with an air cavity 210 extending along the axial direction of the blocking sleeve 200 and not completely penetrating the blocking sleeve 200, and one end of the air cavity 210 forms an outlet. The end of the blocking sleeve 200 away from the outlet is provided with an air pressure interface 220, which can be specifically provided on the side wall or end of the blocking sleeve 200, and preferably, the air pressure interface 220 is provided on the side wall of the blocking sleeve 200 and extends along the radial direction of the blocking sleeve 200. The air pressure interface 220 is in communication with the air cavity 210, and the air pressure interface 220 can be connected to a gas supply device, which can be a gas pump. When the gas supply device is operated, air enters the air cavity 210 through the air pressure interface 220. The blocking sleeve 200 is slidingly arranged in the second connecting hole 120, and specifically, the blocking sleeve 200 is coaxial with the second connecting hole 120, the end of the blocking sleeve 200 provided with the outlet is inserted into the second connecting hole 120, and the end of the blocking sleeve 200 provided with the air pressure interface 220 is located outside the second connecting hole 120, and the blocking sleeve 200 can axially slide in the second connecting hole 120.

[0046] The blocking driving member 400 is connected to the blocking sleeve 200, and the specific connection position is preferably the end of the blocking sleeve 200 located outside the second connecting hole 120. The blocking driving member 400 is suitable for driving the blocking sleeve 200 to slide along the second connecting hole 120. In the embodiment, the blocking driving member 400 can be a telescopic driving device arranged along the axial direction of the second connecting hole 120, which can be, for example, a hydraulic cylinder, a pneumatic cylinder or a telescopic motor. Preferably, the blocking driving member 400 is a pneumatic cylinder.

[0047] The top block 300 is slidingly arranged in the blocking sleeve 200, and the top block 300 is suitable for sliding into the second connecting hole 120 from the outlet under the action of air pressure and sliding along the second connecting hole 120. When the top block 300 slides along the axial direction of the blocking sleeve 200, the side wall of the top block 300 is in close contact with the side wall of the air cavity 210, so that the fluid can be prevented from passing between the side wall of the top block 300 and the side wall of the blocking sleeve 200. Similarly, when the top block 300 slides along the second connecting hole 120, the side wall of the top block 300 is in close contact with the side wall of the second connecting hole 120, so that the fluid can be prevented from passing between the side wall of the top block 300 and the side wall of the second connecting hole 120.

[0048] In the above scheme, one end of the second connecting hole 120 is used as a discharge port for connecting the next station, and the blocking sleeve 200 slides into the second connecting hole 120 from the other end, and the telescopic driving device is used to drive the blocking sleeve 200 to slide to adjust the position of the blocking sleeve 200 in the second connecting hole 120. Referring to Figure 1When the blocking sleeve 200 is located at the position where the first connecting hole 110 and the second connecting hole 120 meet and away from the outlet end of the second connecting hole 120, the material liquid in the first connecting hole 110 can flow into the second connecting hole 120 and flow out through the outlet end of the second connecting hole 120; with reference to Figure 2 When the blocking sleeve 200 is located at the position where the first connecting hole 110 and the second connecting hole 120 meet, the blocking sleeve 200 can block the first connecting hole 110.

[0049] It can be understood that during the operation of the feeding device, the material liquid in the feeding device needs to be guided into the second connecting hole 120 through the first connecting hole 110 and then guided to the next station by the second connecting hole 120, therefore, the blocking sleeve 200 is located at the position shown in Figure 1 , and preferably, the upper edge of the blocking sleeve 200 is flush with the lower edge of the position where the first connecting hole 110 and the second connecting hole 120 meet, and the top block 300 is located at the position of the inlet and outlet of the blocking sleeve 200. When the feeding device stops operating and the material liquid in the second connecting hole 120 needs to be discharged, in order to avoid the material liquid flowing back to the first connecting hole 110, the top block 300 being hindered or tilted at the position where the first connecting hole 110 and the second connecting hole 120 meet, and the gas in the air cavity 210 flowing into the first connecting hole 110, etc., the blocking sleeve 200 needs to be driven upward by the telescopic driving device until the first connecting hole 110 is blocked, and then the gas in the air cavity 210 is supplied by the gas pressure interface 220, so that the top block 300 slides out of the blocking sleeve 200 and slides along the second connecting hole 120.

[0050] It can be further understood that the first connecting hole 110 in the three-way seat block 100 is directly connected to the outlet position of the feeding device, has a short length, and has less residual material liquid, and will not cause much waste under the condition of not being discharged. The second connecting hole 120 is used to be connected to the next station and usually has a large length. The present embodiment can greatly reduce the waste of material liquid by discharging the material liquid in the second connecting hole 120 by the top block 300, which is beneficial to material saving and emission reduction.

[0051] In some embodiments of the present application, the top block 300 is an elastic member, which can be an elastic rubber member. The top block 300 is adapted to be in elastic contact with the side wall of the second connecting hole 120 and the side wall of the air cavity 210.

[0052] It can be understood that the diameter of the top block 300 can be greater than the diameter of the second connecting hole 120 in sliding fit with the top block 300 and the diameter of the air cavity 210, so that the top block 300 is always in elastic contact with the side wall of the second connecting hole 120 and the side wall of the air cavity 210; the diameter of the top block 300 can also be equal to or slightly smaller than the diameter of the second connecting hole 120 in sliding fit with the top block 300 and the diameter of the air cavity 210, when the material liquid in the second connecting hole 120 is discharged, the ends of the top block 300 are extruded by air and material liquid, so that the side wall of the top block 300 deforms outwardly and forms elastic contact with the side wall of the second connecting hole 120 and the side wall of the air cavity 210.

[0053] Further, as shown in Figure 3 In order to make the top block 300 have better connection effect between the second connecting hole 120 and the plugging sleeve 200, the top block 300 can be provided with at least one of the following two structures:

[0054] The first groove 310 is located at one end of the top block 300 close to the air pressure interface 220;

[0055] The second groove 320 is located at one end of the top block 300 away from the air pressure interface 220.

[0056] The first groove 310 and the second groove 320 in the above scheme are both beneficial to the deformation of the end of the top block 300 outwardly when the outer side of the end of the top block 300 is subjected to external force, thereby increasing the sealing performance. Specifically, taking the position of the first groove 310 as an example, when the top block 300 is subjected to extrusion by the gas introduced through the air pressure interface 220, on the one hand, the force of the compressed air acting on the lower end of the top block 300 includes a component force along the radial direction of the top block 300, which promotes the deformation of the position of the top block 300 outside the first groove 310 outwardly, on the other hand, the movement of the top block 300 is subjected to frictional force and the reaction force of the material liquid, and under the combined action of the frictional force, the reaction force of the material liquid and the gas pressure, the length of the top block 300 can be shortened, and correspondingly, the diameter of the top block 300 is increased, thereby further increasing the sealing performance. The principle of the position of the second groove 320 is the same as that of the first groove 310, which will not be described in detail here.

[0057] Optionally, the first groove 310 and the second groove 320 are both arc-shaped grooves, so that the ends of the top block 300 are more prone to deformation.

[0058] Optionally, the top block 300 is provided with the first groove 310 and the second groove 320 at the same time, and the depth of the first groove 310 is greater than the depth of the second groove 320. This arrangement has the following advantages: on the one hand, the second groove 320 has a smaller depth, which can avoid the second groove 320 retaining more materials; on the other hand, the first groove 310 has a greater depth, which means that the top block 300 is more prone to deformation at the position of the first groove 310, and can form a greater force between the side wall of the second connecting hole 120 and the side wall of the air cavity 210, while the first groove 310 position is opposite, which not only ensures the sealing effect of the contact position, but also makes the top block 300 slide more smoothly when ejecting the material.

[0059] In some embodiments of the present application, the second connecting hole 120 includes a first hole section 121 and a second hole section 122 connected at the end, the diameter of the first hole section 121 is the same as the inner diameter of the plugging sleeve 200, the diameter of the second hole section 122 is the same as the outer diameter of the plugging sleeve 200, the plugging sleeve 200 is slidingly arranged in the second hole section 122, and the first connecting hole 110 is connected to the second hole section 122.

[0060] In the above scheme, the first hole section 121 serves as a flow channel for the material liquid, and the end thereof away from the second hole section 122 is connected to the next station. Since the diameter of the first hole section 121 is the same as the inner diameter of the plugging sleeve 200, the top block 300 can be smoothly slid into the first hole section 121 from the air cavity 210. The diameter of the second hole section 122 is greater than or equal to the diameter of the plugging sleeve 200, so that the plugging sleeve 200 can slide along the second hole section 122. When the plugging sleeve 200 slides to the position where the first hole section 121 and the second hole section 122 are connected, the end of the plugging sleeve 200 is connected to the end of the first hole section 121.

[0061] In this scheme, in order to avoid liquid leakage, the sealing between the plugging sleeve 200 and the second hole section 122 should be ensured. Specifically, the outer diameter of the plugging sleeve 200 can be made the same as the diameter of the second hole section 122. When the outer diameter of the plugging sleeve 200 is smaller than the diameter of the second hole section 122, an annular groove can be arranged on the outside of the plugging sleeve 200, and a sealing ring can be installed in the annular groove. Of course, when the outer diameter of the plugging sleeve 200 is the same as the diameter of the second hole section 122, a sealing ring can also be installed to further increase the sealing effect. Further, the installation position of the sealing ring is located at the end of the plugging sleeve 200 close to the first hole section 121.

[0062] Optionally, the position where the second hole section 122 and the first hole section 121 are connected is arranged as a stepped structure, and correspondingly, the end of the plugging sleeve 200 is arranged as a stepped structure, which can make the plugging sleeve 200 form better cooperation with the three-way seat block 100 when the plugging sleeve 200 moves to the end of the second hole section 122, further avoiding the situation of liquid leakage.

[0063] Optionally, the position where the second connecting hole 120 meets the first connecting hole 110 is the position where the second hole section 122 is close to the first hole section 121, so that the length of the second hole section 122 can be effectively shortened, and the moving distance of the plugging sleeve 200 can be reduced.

[0064] According to the discharging device, the support 500 is fixedly connected with the three-way seat block 100, the support 500 comprises a first connecting part, a second connecting part and a mounting part, the first connecting part and the second connecting part extend along the axial direction of the second connecting hole 120 respectively, and are fixedly connected with the three-way seat block 100, and the mounting part is arranged along the radial direction of the second connecting hole 120, one end of the mounting part is connected with the first connecting part, and the other end of the mounting part is connected with the second connecting part. The plugging driving part 400 is fixedly connected with the support 500, and is fixedly connected with the mounting part in particular. The support 500 can support the plugging driving part 400, and provide a moving space for the plugging sleeve 200.

[0065] The first connecting part, the second connecting part and the mounting part in the support 500 can be plate-shaped structures or rod bodies, and form a door-shaped support structure. Of course, in some optional modes, the support 500 can further comprise other plate bodies, so that the support 500 forms a box-shaped structure, and the plugging sleeve 200 is protected.

[0066] When the plugging driving part 400 adopts a telescopic driving structure, a through hole can be arranged on the mounting part, and when the fixed part (for example, a cylinder) of the plugging driving part 400 is mounted to the mounting part, the telescopic part of the plugging driving part 400 is fixedly connected with the plugging sleeve 200 through the through hole.

[0067] The embodiment of the present application further provides a discharging system, which comprises a gas supply device and the above-mentioned discharging device, and the gas supply device is in communication with the gas pressure interface 220 through a pipeline. The gas supply device can directly adopt a gas pump, or a gas storage tank can be used. The air supplied by the gas supply device into the gas cavity 210 can provide power for the movement of the top block 300.

[0068] Optionally, the discharging system further comprises:

[0069] a pressure sensor, configured to detect the outlet pressure of the second connecting hole 120;

[0070] a controller, connected with the gas supply device and the pressure sensor, configured to control the operation of the gas supply device according to the detection signal of the pressure sensor.

[0071] Thus, the automatic control function can be realized. Specifically, the outlet pressure of the second connecting hole 120 detected by the pressure sensor includes two parts, one part is the outlet pressure of the first connecting hole 110 when the feeding device is running, and the other part is the real-time detection pressure of the outlet of the second connecting hole 120 when the residual liquid is discharged by the top block 300, and the controller controls the running of the gas supply device according to the two pressure values detected by the pressure sensor. Preferably, the controller can control the gas supply device to adjust the gas supply pressure, so that the outlet pressure of the second connecting hole 120 when the top block 300 pushes the liquid to discharge is the same as the outlet pressure of the second connecting hole 120 when the feeding device runs. Thus, not only the function of discharging the liquid in the second connecting hole 120 can be realized, but also the normal product (the same as the product formed when the feeding device runs) can be formed after the liquid is discharged.

[0072] In some embodiments of the present application, the discharging system further comprises:

[0073] a negative pressure device;

[0074] a three-way valve, three valve ports of the three-way valve are connected with the gas pressure interface 220, the gas outlet of the gas supply device and the gas inlet of the negative pressure device respectively.

[0075] The three-way valve can switch the connection path of the gas pressure interface 220 with the gas supply device and the negative pressure device. When it is needed to discharge the liquid in the first connecting hole 110, the three-way valve is switched to the state that the gas pressure interface 220 is connected with the gas supply device, the gas supply device is running, and the gas supplied by the gas supply device enters the gas cavity 210 to push the top block 300 to move in the direction of discharging the liquid. When the discharging is completed, the three-way valve is switched to the state that the gas pressure interface 220 is connected with the negative pressure device, and the negative pressure device is running, and the negative pressure formed by the negative pressure device can reset the top block 300.

[0076] Optionally, the three-way valve is an electrically controlled three-way valve, and the three-way valve is electrically connected with the controller, and the controller can control the action of the three-way valve.

[0077] It should be noted that the pipeline connected with the gas pressure interface 220 adopts a flexible pipe body structure, so as to adapt to the movement of the plugging sleeve 200.

[0078] In the above scheme, a scheme for resetting the top block 300 by using the negative pressure principle is provided. In some other optional schemes, other ways such as taking out the top block 300 after disassembling the three-way seat block 100 and then putting the top block 300 back into the plugging sleeve 200 can be used for resetting.

[0079] The embodiment of the present application further provides a food production equipment, which comprises a feeding device, and further comprises the above-mentioned discharging device or the above-mentioned discharging system, and the feeding device is connected with the first connecting hole 110.

[0080] The food production equipment according to the embodiment of the present application can be an ice cream production equipment, and further, the feeding device can be a freezing device. Of course, the video production equipment according to the embodiment of the present application can also be other equipment than the ice cream production equipment, in other words, as long as the discharge device or the discharge system according to the embodiment of the present application can be used, which is not limited here.

[0081] As shown in Figure 4 The present application also provides a control method of the discharge device, which can be correspondingly referred to the discharge device described above.

[0082] The control method of the discharge device according to the embodiment of the present application comprises:

[0083] S100, when the feeding device connected with the first connecting hole 110 is running, the sealing sleeve 200 is located outside the position where the first connecting hole 110 and the second connecting hole 120 are connected;

[0084] S200, when the feeding device connected with the first connecting hole 110 is stopped running, the sealing sleeve 200 is driven to seal the first connecting hole 110, and then the gas pressure interface 220 is supplied with gas.

[0085] In the above steps, when the feeding device is running, the sealing sleeve 200 moves away from the position where the first connecting hole 110 is connected, and at this time, the top block 300 is located in the sealing sleeve 200, and the liquid supplied by the feeding device can enter the second connecting hole 120 through the first connecting hole 110 and be guided out of the second connecting hole 120. When the feeding device is stopped running, the sealing driving member 400 drives the sealing sleeve 200 to move axially along the second connecting hole 120, and when the sealing sleeve 200 moves to the position where the first connecting hole 110 and the second connecting hole 120 are connected, the sealing sleeve 200 can seal the first connecting hole 110 to block the passage between the first connecting hole 110 and the second connecting hole 120, and then the gas pressure interface 220 is supplied with gas by the gas supply device, and the top block 300 can slide along the sealing sleeve 200 and the second connecting hole 120 under the action of the gas pressure to discharge the liquid in the second connecting hole 120.

[0086] Further, the step S200 of supplying the gas pressure interface 220 with gas comprises:

[0087] S201, when the feeding device connected with the first connecting hole 110 is running, the outlet pressure of the second connecting hole 120 is taken as a preset pressure, and the gas supply pressure of the gas pressure interface 220 is adjusted based on the real-time detection value of the outlet pressure of the second connecting hole 120 to make the outlet pressure of the second connecting hole 120 equal to the preset pressure.

[0088] In the above steps, the outlet pressure of the second connecting hole 120 when the feeding device is running and the outlet pressure of the second connecting hole 120 when the feeding device is stopped can be detected by a pressure sensor arranged at the outlet position of the second connecting hole 120. When the liquid in the second connecting hole 120 is discharged, the second connecting hole 120 outlet pressure is equal to the preset pressure by adjusting the gas pressure, which can ensure that the product formed when the remaining liquid is discharged is the same as the product formed when the feeding device is running, ensure the yield, and avoid product quality problems.

[0089] Optionally, after step S200, the method further comprises:

[0090] S300, after the top block 300 pushes out all the liquid in the second connecting hole 120, a negative pressure is provided to the gas pressure interface 220 to reset the top block 300 to the plugging sleeve 200;

[0091] S400, drive the plugging sleeve 200 to move away from the position where the first connecting hole 110 and the second connecting hole 120 are connected.

[0092] In the above scheme, after the top block 300 and the plugging sleeve 200 are reset in turn, the first connecting hole 110 and the second connecting hole 120 are connected, which can prepare for the next operation of the feeding device.

[0093] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
