Description

Technical Field

[0001] This utility model belongs to the technical field of food machinery, and relates to a small automatic dumpling machine. Background Technology

[0002] Existing small dumpling machines mainly achieve dumpling forming through a rolling clamping device. For example, Chinese utility model patent CN203564140U discloses a household automatic small dumpling machine, including a frame, a filling dispensing mechanism, a rolling clamping device, a filling pushing device, and a dumpling skin pushing device. The frame contains a small electric motor and transmission mechanism. The filling dispensing mechanism is installed on the upper part of the frame, with a filling outlet at the front. Above the filling outlet is a filling pushing device that can move up and down. Below the filling outlet is a rolling clamping device with a forming groove composed of two hemispherical concave grooves located directly below the filling outlet. A dumpling skin bucket is located at the front of the clamping device, with a spring at the bottom. An automatic dumpling skin pushing device is located at the top of the dumpling skin bucket, with a dumpling skin claw at the upper front of the automatic dumpling skin pushing device.

[0003] Although such equipment achieves basic automation, it has significant shortcomings in terms of molding flexibility, which limits its application scenarios. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a small automatic dumpling machine, which has the advantages of simple structure, small footprint, high degree of automation, fast production speed, and high forming flexibility.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0006] A small automatic dumpling machine includes a filling conveying mechanism, a dumpling forming mechanism, and a dumpling conveying mechanism mounted on a frame. The dumpling forming mechanism includes a left mold, a right mold, and a middle mold. The upper and lower sides of the middle mold are respectively provided with dumpling belly forming grooves. The inner surfaces of the left and right molds are provided with dumpling edge forming grooves. When the left and right molds are closed, the dumpling edge forming grooves of both molds and the dumpling belly forming groove on the upper side of the middle mold jointly form dumplings. The middle mold rotates periodically so that the dumpling belly forming grooves switch between the upper forming station and the lower output station. When the dumpling belly forming groove is in the forming station, it receives the filling conveyed by the filling conveying mechanism; when it is in the output station, it releases the formed dumplings to the dumpling conveying mechanism.

[0007] In the aforementioned small automatic dumpling machine, the frame includes two opposing upright plates, with guide rails on opposite sides of the upright plates. The left and right molds are respectively fixedly connected to crossbeams, which are slidably mounted on the guide rails. The middle mold is rotatably connected to the upright plates via a middle mold pivot.

[0008] In the aforementioned small automatic dumpling machine, the dumpling conveying mechanism is a conveyor belt disposed between the upright plates and extending outside the machine frame, and the conveyor belt is circulated by conveying rollers driven by a power unit.

[0009] In the aforementioned small automatic dumpling machine, a central mold drive shaft driven by a power device is rotatably mounted on the frame, and the central mold drive shaft is connected to the central mold rotating shaft via a transmission connection; preferably, sprockets are respectively mounted on the central mold drive shaft and the central mold rotating shaft, and are connected via a meshing chain transmission connection.

[0010] In the aforementioned small automatic dumpling machine, a mold-closing drive shaft driven by a power device is rotatably mounted on the frame, and a drive gear is fitted at its end. A driven gear meshes with one side of the drive gear, and a drive link is eccentrically hinged to the end face of each of the drive gear and the driven gear. The other ends of the two drive links are respectively hinged to the ends of the left mold and right mold crossbeams.

[0011] In the aforementioned small automatic dumpling machine, a cover plate is provided above the left mold, right mold and middle mold. The cover plate has through holes corresponding to the middle mold and filling conveying mechanism. A dumpling skin placement and positioning groove is covered above the through holes. Furthermore, the cover plate is fixedly connected to the upper end face of the upright plate by fasteners.

[0012] In the aforementioned small automatic dumpling machine, the middle mold drive shaft extends out of the outer vertical plate and is fitted with a first bevel gear. A horizontally rotating rocker arm is hinged to the cover plate. The dumpling skin placement and positioning groove is fixed to the end of the rocker arm. A second bevel gear that meshes with the first bevel gear is fitted on the rotating shaft of the rocker arm. The rocker arm swings back and forth between the dumpling skin loading position on the outer side and the working position of the cover plate.

[0013] In the aforementioned small automatic dumpling machine, the middle mold drive shaft, the mold closing drive shaft, and the conveying roller can be driven by their respective independent power devices or by the same power device. When the middle mold drive shaft, the mold closing drive shaft, and the conveying roller are all driven by the same power device, the power device distributes power to the middle mold drive shaft, the mold closing drive shaft, and the conveying roller through a gearbox.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. This utility model provides a small automatic dumpling machine, which uses a forming mold composed of a left mold, a right mold, and a middle mold. The dumpling belly forming groove and the two dumpling edge forming grooves form a forming cavity with the same shape as the dumpling, thereby forming more beautiful dumplings. At the same time, this utility model uses the dumpling edge forming grooves to seal the edges. When using left and right molds with different dumpling edge forming grooves, dumplings of different shapes can be formed to meet diverse needs.

[0016] 2. This utility model features a rotatable middle mold, which improves the automation level of the dumpling machine. The middle mold has two dumpling-forming grooves, and by rotating the middle mold, it periodically rotates between the forming station and the output station. When the forming station is forming, the output station simultaneously unloads the dumplings. Combined with the dumpling conveying mechanism, this achieves automatic dumpling forming and automatic conveying. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :

[0022] A small automatic dumpling machine includes a filling conveying mechanism 2, a dumpling forming mechanism 3, and a dumpling conveying mechanism 4 mounted on a frame 1. The dumpling forming mechanism 3 includes a left mold 31, a right mold 32, and a middle mold 33. The upper and lower sides of the middle mold 33 are respectively provided with dumpling belly forming grooves 34. The inner surfaces of the left mold 31 and the right mold 32 are provided with dumpling edge forming grooves 35. When the left mold 31 and the right mold 32 are closed, the dumpling edge forming grooves 35 of the two molds and the dumpling belly forming grooves 34 on the upper side of the middle mold 33 jointly form dumplings. The middle mold 33 rotates periodically so that the dumpling belly forming grooves 34 switch between the upper forming station and the lower output station. When the dumpling belly forming grooves 34 are in the forming station, they receive the filling conveyed by the filling conveying mechanism 2. When they are in the output station, they release the formed dumplings to the dumpling conveying mechanism 4.

[0023] The working process of this embodiment is as follows: The filling is placed into the filling conveying mechanism 2 (the filling conveying mechanism 2 in this embodiment is the same as in the prior art, including a filling hopper, a horizontally arranged auger, a vertically arranged filling pipe, and a stamping rod coaxially arranged inside the filling pipe; the auger conveys the filling from the side to the filling pipe, and the stamping rod presses the filling entering the filling pipe downwards to detach it from the filling pipe). The dumpling wrapper is placed above the middle mold 33. After starting the equipment, the filling conveying mechanism 2 conveys the filling onto the dumpling wrapper and presses it down to wrap the filling and allow it to enter the middle mold 33. In the belly forming groove 34, at this time, the edge of the dumpling skin extends beyond the upper edge of the dumpling belly forming groove 34. Then, the left mold 31 and the right mold 32 close, and the dumpling edge forming groove 35 of the left mold 31 and the right mold 32 squeezes the edge of the dumpling skin to seal it and produce the same pattern as the dumpling edge forming groove 35. Then, the left mold 31 and the right mold 32 open, and at the same time, the middle mold 33 rotates 180°, so that the dumpling belly forming groove 34 flips to the output station. The wrapped dumpling comes out of the dumpling belly forming groove 34 and falls into the dumpling conveying mechanism 4 for outward conveying. Another dumpling belly forming groove 34 rotates to the forming station to make the next dumpling.

[0024] Furthermore, in this embodiment, the installation structure of the left mold 31, right mold 32, and middle mold 33 is as follows: the frame 1 includes two opposing upright plates 11, and guide rails 12 are provided on the opposite sides of the upright plates 11. The left mold 31 and right mold 32 are respectively fixedly connected to crossbeams 13, and the crossbeams 13 are slidably disposed on the guide rails 12. The middle mold 33 is rotatably connected to the upright plates 11 through the middle mold rotating shaft 36.

[0025] Furthermore, the specific structure of the dumpling conveying mechanism 4 in this embodiment is as follows: the dumpling conveying mechanism 4 is a conveyor belt 41 arranged between the upright plates 11 and extending outside the frame 1. The conveyor belt 41 is circulated by a conveyor roller driven by a power device; the dumplings falling from the middle mold 33 fall onto the conveyor belt 41 and are conveyed to the outside of the frame 1 along with the conveyor belt 41 to complete the unloading.

[0026] In this embodiment, the driving structure of mold 33 is as follows: a middle mold drive shaft 14 driven by a power device is rotatably mounted on the frame 1, and the middle mold drive shaft 14 is connected to the middle mold rotating shaft 36 in a transmission connection; preferably, sprockets are respectively mounted on the middle mold drive shaft 14 and the middle mold rotating shaft 36, and are connected by meshing chains in a transmission connection; the power device periodically drives the middle mold drive shaft 14 to rotate, the middle mold drive shaft 14 drives the middle mold 33 to rotate, and the middle mold 33 mounted on the middle mold rotating shaft 36 rotates accordingly, realizing the switching of the workstation of the dumpling belly forming groove 34.

[0027] The mold-closing drive structure in this embodiment is as follows: A mold-closing drive shaft 15 driven by a power device is rotatably mounted on the frame 1, and a drive gear 16 is fitted at its end. A driven gear 17 (rotatably mounted on the frame 1 and identical to the drive gear 16) meshes with one side of the drive gear 16. A drive link 18 is eccentrically hinged to the end face of each of the drive gear 16 and the driven gear 17. The other ends of the two drive links 18 are respectively hinged to the ends of the crossbeams 13 of the left mold 31 and the right mold 32. The power device drives the mold-closing drive shaft 15 to rotate, which in turn drives the drive gear 16 to rotate. The driven gear 17 meshing with the drive gear 16 rotates in the opposite direction. During the rotation, the drive links 18 pull the left mold 31 and the right mold 32 to slide along the guide rail 12.

[0028] The aforementioned intermediate mold drive shaft 14, mold closing drive shaft 15, and conveyor roller can be driven by their respective independent power units or by the same power unit. When the intermediate mold drive shaft 14, mold closing drive shaft 15, and conveyor roller are all driven by the same power unit, the power unit distributes power to the intermediate mold drive shaft 14, mold closing drive shaft 15, and conveyor roller through gearbox 19. For example, a motor drives the main shaft to rotate via a synchronous belt, and the main shaft distributes power to the intermediate mold drive shaft 14, mold closing drive shaft 15, and conveyor roller through gear or sprocket chain transmission to drive the intermediate mold drive shaft 14, mold closing drive shaft 15, and conveyor roller to rotate. The mold closing drive shaft 15 and conveyor roller rotate continuously, while the intermediate mold drive shaft 14 achieves periodic rotation through a half-gear or other transmission method. During the mold closing process driven by the mold closing drive shaft 15, the intermediate mold 33 remains stationary. During the mold opening process driven by the mold closing drive shaft 15, the intermediate mold drive shaft 14 drives the intermediate mold 33 to rotate.

[0029] In this embodiment, the dumpling wrapper feeding structure is as follows: a cover plate 51 is provided on the top of the left mold 31, the right mold 32 and the middle mold 33. The cover plate 51 has through holes 52 corresponding to the middle mold 33 and the filling conveying mechanism 2. A dumpling wrapper placement positioning groove 53 is covered above the through holes 52. Furthermore, the cover plate 51 is fixedly connected to the upper end face of the upright plate 11 by fasteners. When feeding, the dumpling wrapper can be manually placed into the dumpling wrapper placement positioning groove 53.

[0030] This embodiment also provides an automatic dumpling wrapper feeding mechanism to further automate dumpling production: the middle mold drive shaft 14 extends through the outer upright plate 11 and is fitted with a first bevel gear; a horizontally rotating rocker arm is hinged on the cover plate 51; the dumpling wrapper placement positioning groove 53 is fixed to the end of the rocker arm; a second bevel gear meshing with the first bevel gear is fitted on the rotating shaft of the rocker arm; the rocker arm swings back and forth between the outer dumpling wrapper feeding position and the working position of the cover plate 51; the dumpling wrapper is placed on the dumpling wrapper placement positioning groove 53 outside the frame 1; when the middle mold drive shaft 14 rotates, the rocker arm swings inward, causing the dumpling wrapper placement positioning groove 53 to move above the through hole 52, thus completing the dumpling wrapper feeding.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
