[0040] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0041] Combination Figures 1 to 9 As shown, according to a specific embodiment of the present application, an automatic discharging device is provided.

[0042] The automatic discharging device comprises: a first housing 10 and a sliding assembly 20. The first housing 10 has a feeding channel 11 and a leakage cavity 12 connected to the feeding channel 11, and a leakage port 13 is arranged on the side wall of the leakage cavity 12; the sliding assembly 20 is located in the leakage cavity 12, and the sliding assembly 20 is slidably arranged relative to the first housing 10, and the sliding assembly 20 has a closed position in which the sliding assembly 20 moves toward the feeding channel 11 to block the leakage port 13, and an open position in which the sliding assembly 20 moves away from the feeding channel 11 to at least partially open the leakage port 13.

[0043] By applying the technical solution of the present application, by constructing the feeding channel 11 and the material leakage cavity 12 in the first housing 10, and using the sliding component 20 to at least partially open or close the material leakage port 13 provided on the material leakage cavity 12, the automatic discharging device can realize the automatic feeding of seasonings by controlling the sliding position of the sliding component 20, thereby reducing the manual labor intensity and improving the food production efficiency. The present application solves the problem of high labor intensity of personnel caused by manual feeding in the prior art.

[0044] Optionally, the feeding channel 11 is communicated with the material storage space, or is communicated with the material box.

[0045] Furthermore, the sliding assembly 20 includes: a slider 21, which is arranged in the leakage chamber 12, and the slider 21 and the first shell 10 can be slidably arranged relative to each other, and a accommodating chamber 211 is arranged inside the slider 21; a rotating member 22, part of the rotating member 22 is located in the accommodating chamber 211, and a three-dimensional guide rail 221 is arranged on the outer peripheral surface of the part of the rotating member 22 located in the accommodating chamber 211, and the length of the rotating member 22 is less than the length of the accommodating chamber 211; a spring ejector 23, which is arranged in the slider 21, and part of the spring ejector 23 extends into the accommodating chamber 211 and abuts against the bottom wall of the three-dimensional guide rail 221; wherein, when the rotating member 22 rotates around its own central axis, the three-dimensional guide rail 221 drives the spring ejector 23 to move in the three-dimensional guide rail 221, thereby driving the slider 21 to slide relative to the first shell 10. This arrangement converts the rotational motion of the rotating member 22 into the translational motion of the slider 21 relative to the first housing 10. Compared with the solution of using a gear rack to drive the slider 21, the overall volume is smaller and it is convenient to arrange in the first housing 10. The axial displacement of the slider 21 can be determined by one rotation of the rotating member 22, thereby realizing automatic and accurate feeding.

[0046] Since both the rotating member 22 and the slider 21 can be configured as cylindrical structures, it is beneficial to improve the sealing performance between the slider 21 and the first housing 10. The rotating member 22 and the slider 21 can be coaxially configured to further reduce the volume of the sliding assembly.

[0047] Optionally, the internal chamber of the accommodating chamber 211 is filled with food-grade grease so that the internal chamber and the outside are completely sealed.

[0048] Further, the rotating member 22 has a first rotation state of clockwise rotation around its own central axis, and the rotating member 22 has a second rotation state of counterclockwise rotation around its own central axis. When the rotating member 22 is in the first rotation state, the slider 21 slides relative to the first shell 10 toward the side of the feed channel 11, and when the rotating member 22 is in the second rotation state, the slider 21 slides relative to the first shell 10 along the side away from the feed channel 11. In other words, when the rotating member 22 rotates forward, the slider 21 slides relative to the first shell 10 toward the side of the feed channel 11, and when the rotating member 22 rotates reversely, the slider 21 slides relative to the first shell 10 along the side away from the feed channel 11. The above embodiment uses a set of devices to achieve the reciprocating motion of the slider 21, thereby achieving the opening or closing of the discharge port.

[0049] The spline rotates, driving the guide rail to rotate, and the spring ejector pin is forced to slide along the guide rail, causing the slider to move forward to open when the spline rotates in the forward direction, and move backward to close when the spline rotates in the reverse direction.

[0050] Further, the rotating member 22 includes: a rotating body 222, the rotating body 222 is located in the accommodating cavity 211, and a three-dimensional guide rail 221 is provided on the outer peripheral surface of the rotating body 222; an input shaft 223, the first end of the input shaft 223 is connected to the rotating body 222, the second end of the input shaft 223 extends to the leakage cavity 12 or the feeding channel 11, and the second end of the input shaft 223 is provided with an assembly part for connecting with an external power source. By providing the input shaft 223, external power can be introduced into the rotating member 22, such as the rotational power of the screw feeding mechanism, and there is no need to add a power device in the discharging device.

[0051] When the rotating body 222 is driven to rotate by the input shaft 223, the three-dimensional guide rail 221 rotates accordingly, and the spring ejector pin 23 is forced to slide along the three-dimensional guide rail 221, so that the slider moves forward (toward the feed channel) to open when the rotating body 222 rotates forward, and moves backward (away from the feed channel) to close when the rotating body 222 rotates in the reverse direction.

[0052] Optionally, the feed channel 11 and the leakage chamber 12 are adjacent to and connected to each other along the axial direction of the first shell 10, and the sliding assembly 20 is arranged at one end of the leakage chamber 12 away from the feed channel 11. The leakage chamber 12 is formed by a part of the inner cavity wall of the first shell 10 and the end side wall of the sliding assembly 20 facing the feed channel 11, that is, as the sliding assembly 20 moves, the volume of the leakage chamber 12 is variable.

[0053] Furthermore, there are two spring ejector pins 23, and the two spring ejector pins 23 are symmetrically arranged relative to the central axis of the slider 21. This arrangement can make the sliding assembly move more smoothly and react more quickly.

[0054] Furthermore, along the extension direction of the three-dimensional guide rail 221, the groove depths of at least two locations of the three-dimensional guide rail 221 are set differently. In other words, the three-dimensional guide rail 221 is a variable height guide rail, and since the spring ejector pin 23 has elasticity along its own axial direction, it can follow the rotation of the three-dimensional guide rail 221 to drive the translation of the slider.

[0055] Furthermore, the automatic discharging device further includes: an end plate 30, which is disposed in the leakage cavity 12, and is connected to the side of the slider 21 facing the feed channel 11, and the input shaft 223 extends into the leakage cavity 12 or the feed channel 11 after passing through the end plate 30. The end plate 30 can effectively prevent the liquid in the leakage cavity 12 from entering the gap between the slider 21 and the first housing 10, thereby ensuring the allowable accuracy of the slider 21 and extending its service life.

[0056] Furthermore, the end plate 30 is connected to the slider 21 through at least one set of connecting members 31 , and the set of connecting members 31 includes screws and sealing gaskets assembled with the screws.

[0057] Furthermore, a sealing ring 32 is provided between the end plate 30 and the first shell 10 .

[0058] Furthermore, the first shell 10 is provided with an isolation plate, which extends inward from the side wall of the first shell 10. The isolation plate partially isolates the feed channel and the leakage chamber 12 so that the feed channel and the leakage chamber 12 can still be connected. The input shaft 223 passes through the end plate 30 and is connected to the isolation plate. The isolation plate is used to provide radial support and axial limitation for the input shaft 223.

[0059] Furthermore, an oil seal structure 33 is provided between the end plate 30 and the input shaft 223. The oil seal structure 33 can realize a reciprocating sealing effect of bidirectional rotation.

[0060] Furthermore, a U-shaped limiting groove 14 is provided at one end of the first housing 10 close to the sliding assembly 20, and a limiting column 212 is connected to the slider 21. During the relative sliding of the slider 21 and the first housing 10, the limiting column 212 is located in the U-shaped limiting groove 14 and slides relative to the U-shaped limiting groove 14. Through the cooperation between the U-shaped limiting groove 14 and the limiting column 212, the sliding limit of the sliding assembly 20 is realized, and the movement stroke of the sliding assembly 20 is limited.

[0061] According to one aspect of the present invention, there is provided a material box, including an automatic discharging device, the automatic discharging device is the above-mentioned automatic discharging device, the material box includes: a box body 100, a clamping piece 107 is provided on the box body 100, a first shell body 10 is provided with a clamping portion 108, and the clamping piece 107 is connected to the clamping portion 108.

[0062] Through the cooperation of the clamping portion 108 and the clamping piece 107, a step cooperation design is realized to prevent the automatic discharging device from falling off.

[0063] Furthermore, the box body 100 has a discharge port 101 , at least part of the discharge port 101 is located in the feed channel 11 , and a sealing silicone gasket is arranged between the end of the discharge port 101 away from the box body 100 and the first shell.

[0064] Furthermore, the box body 100 is provided with a screw conveying mechanism 102, one end of which extends into the discharge port 101, and the screw conveying mechanism 102 includes a screw rod 103, a spline groove 104 is provided at the end of the screw rod 103, a spline 2231 is provided at the second end of the input shaft 223, and the spline 2231 and the spline groove 104 are assembled so that the power of the screw rod 103 is transmitted to the input shaft 223. This arrangement ingeniously uses the power of the screw conveying mechanism 102 to automatically control the opening and closing of the automatic discharge device, realizes the unification of the material transportation and feeding actions, and also reduces the overall cost and volume.

[0065] Furthermore, the material box further includes: a quick installation structure 105, the first end of the quick installation structure 105 is connected to the material feeding channel 11 through a hole axis, the second end of the quick installation structure 105 has a clamping cavity 106, and the discharge port 101 is detachably connected to the clamping cavity 106. This arrangement allows the discharge device to cooperate with the disassembly and assembly tool, and can manually open and close the switch mouth, which is convenient for assembly and cleaning.

[0066] Optionally, the screw 103 is a screw with a stainless steel sleeve, which has stronger wear resistance and can maintain a rotary seal for a longer time.

[0067] Optionally, the screw conveying mechanism 102 and the input shaft 223 are matched with splines and features on the screw to transmit torque.
