Description

Technical Field

[0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a full-automatic dumpling machine. Background Art

[0002] Dumplings are a traditional Chinese delicacy. They are deeply loved by Chinese people because they are easy to cook and their fillings can be a combination of meat and vegetables, which is nutritionally balanced. Most families make dumplings by hand, which requires kneading dough, rolling out dough, and wrapping stuffing. The production process is tedious and time-consuming, so fully automatic dumpling machines that can automatically sink, roll out dough, and wrap stuffing have appeared on the market.

[0003] However, the sinking mechanism of the current fully automatic dumpling making machine mostly uses a cutting method to cut the filling and make it fall onto the dumpling wrapper. For example, the Chinese utility model with publication number CN206371384U discloses an automatic dumpling making machine, which uses an electric push rod to connect a pressing plug through a flange to realize the intermittent pressing of the filling by the pressing plug. The servo on the servo bracket drives the filling cutting plate to reciprocate, cuts off the filling coming out of the discharge barrel, and prevents the filling in the discharge barrel from flowing out; since cooking oil is added to the dumpling filling during the preparation process, it has a certain viscosity. Cutting the filling by cutting will cause the filling to stick to the cutting plate, changing its falling trajectory, so that it does not fall onto the dumpling wrapper below, resulting in filling waste, or falls on the edge of the dumpling wrapper, making it difficult to shape the dumplings, affecting the appearance of the dumplings, and the dumpling wrapper is easy to open when boiled, resulting in leakage of filling and affecting the taste. Summary of the Invention

DETAILED DESCRIPTION

[0017] In order to better understand the purpose, structure and function of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] See Figures 1 to 10, a fully automatic dumpling machine is designed, including a shell 2. In this embodiment, the shell 2 is a cubic structure with an open top, and a shell cover is provided on the top of the shell 2. Handles are provided on the exterior facades on both sides of the shell 2 to facilitate moving and carrying the fully automatic dumpling machine. A rectangular array is provided at the bottom of the shell 2 with four legs, and an adjusting piece is provided at the bottom of the legs. The adjusting piece is threadedly connected to the legs, and the level of the dumpling machine is adjusted by screwing the adjusting piece to adapt to different planes. The shell 2 protects the internal components. A dough discharging mechanism 3, a skin pressing mechanism 4, a stuffing discharging mechanism 5 and a dumpling feeding mechanism 6 are respectively installed on the four inner facades of the shell 2 in a clockwise order. The dough discharging mechanism 3 makes dough blocks, the skin pressing mechanism 4 presses the dough blocks into dumpling skins, the stuffing discharging mechanism 5 cuts a piece of dumpling stuffing and drops it on the dumpling skins, and the stuffing discharging mechanism 5 puts the wrapped dumplings The shell 2 is pushed out; a four-station cylinder is installed on the upper surface of the bottom of the shell 2, and a turntable 71 is installed on the top of the four-station cylinder. There are several positioning holes 711 in a circular array on the turntable 71. In this embodiment, there are four positioning holes 711. When the four-station cylinder is in a stopped state, the four positioning holes 711 are respectively located on the orthographic projections of the dough-discharging mechanism 3, the dough-pressing mechanism 4, the stuffing-discharging mechanism 5 and the dumpling-delivering mechanism 6 on the turntable 71. A support 72 is provided in the positioning hole 711, and the support 72 is fixedly connected to the positioning hole 711. A ball is provided at the bottom of the support 72, and the ball fits with the upper surface of the bottom of the shell 2. The ball effectively supports the support 72 when it is pressed by the dough-pressing mechanism 4, and can also reduce the friction between the bottom of the support 72 and the bottom of the shell 2 when the four-station cylinder rotates, thereby reducing resistance. A clamping mechanism 8 is connected to the top of the support 72, which is used to fold the dumplings in half and knead them to form the dumplings; the dough discharging mechanism 3 includes a dough barrel 31, and a dough discharging port is provided at the bottom of the dough barrel 31, and the dough discharging port is detachably connected to the top of the stuffing cutting mechanism; the stuffing discharging mechanism 5 includes a stuffing barrel 51, and a stuffing discharging port is provided at the bottom of the stuffing barrel 51, and the stuffing discharging port is detachably connected to the top of the stuffing cutting mechanism.

[0019] The stuffing cutting mechanism includes a discharge pipe 1, the bottom end of the discharge pipe 1 is a spherical head 12, a stuffing passage is provided in the spherical head 12, the spherical head 12 is provided with a hole-axis connection with two opening and closing parts 13, the spherical head 12 is provided on the shaft 121, the opening and closing part 13 is provided with an axial hole 133, and the two opening and closing parts 13 are opened and closed on the spherical head 12 by the hole-axis cooperation between the shaft 121 and the axial hole 133. The side of the opening and closing part 13 that fits the spherical head 12 is an arcuate surface 131, and the arcuate surface 131 fits the outer surface of the spherical head 12. When the two opening and closing parts 13 are closed, they can form a hemispherical shell. The inner surface of the hemispherical shell fits with the outer surface of the lower half of the spherical head 12. The spherical design makes the rotation process of the two opening and closing parts 13 smoother, and when the two opening and closing parts 13 are opened, the edge of the bottom outlet of the spherical head 12 can scrape the dumpling filling stuck to the arc surface 131, and the scraped dumpling filling is taken away together with the dumpling filling coming out next time, so as not to cause waste of filling. A mounting platform is provided on the fixed sleeve of the discharge pipe 1, and a telescopic push rod motor 14 is installed on the mounting platform. The push rod end of the telescopic push rod motor 14 is connected to a push member 15, and a slide groove 151 is relatively provided on the push member 15, such as Figure 1 The lower parts of the two slides 151 are close to each other, and the upper parts are away from each other. A slide bar 132 is fixed on the opening and closing member 13. Both the opening and closing member 13 and the slide bar 132 are made of stainless steel. The slide bar 132 is welded on the opening and closing member 13. The slide bar 132 and the slide bar 151 form a groove pin pair. When the dumpling stuffing is sent out from the discharge pipe 1 for a section, the telescopic push rod motor 14 is started, driving the pusher 15 to move downward, and the two slide bars 132 are away from each other through the groove pin pair formed by the slide bar 132 and the slide bar 151. The two opening and closing members 13 realize a closing process, thereby putting the dumplings into the filling. The filling is cut off at the center of the bottom outlet of the discharge pipe 1. The cut dumpling filling falls onto the dumpling wrapper directly below due to its own gravity, ensuring that subsequent dumplings can be completely formed. In addition, the two closed opening and closing parts 13 can block the bottom outlet of the discharge pipe 1 to prevent leakage. Then the telescopic push rod motor 14 drives the pushing part 15 to move upward, and the two slide rods 132 and the slide groove 151 are used to form a groove pin pair, so that the two slide rods 132 are close to each other, and the two opening and closing parts 13 complete an opening and closing process, so that the two opening and closing parts 13 avoid the bottom outlet of the discharge pipe 1 and wait for the next filling discharge.

[0020] In this embodiment, the inner wall of the noodle outlet is provided with an internal thread, the outer surface of the top end of the discharge pipe 1 is provided with an external thread, the noodle outlet and the discharge pipe 1 are threadedly connected, the inner wall of the filling outlet is provided with an internal thread, the outer surface of the top end of the discharge pipe 1 is provided with an external thread, and the filling outlet and the discharge pipe 1 are threadedly connected.

[0021] The noodle barrel 31 is equipped with a noodle barrel cover 32, which is threadedly connected to the noodle barrel 31. A noodle adding port 321 is provided on the noodle barrel cover 32 for adding noodles during the operation of the dumpling machine. The noodle adding port 321 is equipped with a dust cover 322 to prevent dust and impurities from falling into the noodle barrel 31. A noodle feeding motor 33 is installed on the noodle barrel cover 32. A noodle feeding roller 34 is connected to the driving shaft of the noodle feeding motor 33. A noodle feeding spiral blade 342 is provided on the upper part of the noodle feeding roller 34. The noodle feeding spiral blade 342 is located in the noodle barrel 31. The side elevation of blade 1 342 is in contact with the inner wall of the noodle barrel 31, and noodle feeding spiral blade 2 341 is provided at the lower part of noodle feeding roller 34, and noodle feeding spiral blade 2 341 is located in the discharge pipe 1, and the outer elevation of noodle feeding spiral blade 2 341 is in contact with the inner elevation of the discharge pipe 1, thereby improving the conveying effect. When the noodle feeding motor 33 drives noodle feeding spiral blade 1 342 and noodle feeding spiral blade 2 341 to rotate, noodle feeding spiral blade 1 342 and noodle feeding spiral blade 2 341 will send the noodle blocks in the noodle barrel 31 to the stuffing cutting mechanism through the discharge pipe 1.

[0022] The noodle feeding motor 33 is a bidirectional motor that can realize forward and reverse rotation. The kneaded dough is put into the noodle barrel 31 and the noodle feeding motor 33 is started. When the noodle feeding motor 33 rotates forward, the noodle feeding spiral blade 1 342 generates thrust to feed the dough into the bottom of the noodle barrel 31. The thrust generated by the noodle feeding spiral blade 2 341 can squeeze the dough at the bottom of the noodle barrel 31 out of the bottom outlet of the spherical head 12. If the dough is put into the noodle barrel 31 and waited for a period of time before being used, the surface of the dough will lose water and dry out, affecting the taste. At this time, the noodle feeding motor 33 is controlled to reverse, and the noodle feeding spiral blade 1 342 and the noodle feeding spiral blade 2 341 will not play a role in feeding the dough, but play a role in mixing the noodle pieces, mixing the noodle pieces evenly. The noodle feeding motor 33 is controlled to rotate forward again to send the re-mixed noodle pieces to the opening and closing part 13 through the discharge pipe 1.

[0023] The filling barrel 51 is equipped with a barrel cover 52, which is threadedly connected to the filling barrel 51. A filling port 521 is provided on the barrel cover 52 for filling operation during the operation of the dumpling machine. The filling port 521 is provided with a dust cover 522 to prevent dust and impurities from falling into the filling barrel 51. A filling motor 53 is installed on the barrel cover 52, and a filling mixing roller 54 is connected to the driving shaft of the filling motor 53. A filling feeding spiral blade 541 is provided at the lower part of the filling mixing roller 54. The filling feeding spiral blade 541 is located in the discharge pipe 1, and the outer surface of the filling feeding spiral blade 541 is fitted with the inner surface of the discharge pipe 1 to improve the conveying effect. When the filling mixing motor 53 drives the filling feeding spiral blade 541 to rotate, the filling feeding spiral blade 541 will feed the dumpling filling in the filling barrel 51 to the filling cutting mechanism through the discharge pipe 1.

[0024] The upper part of the stuffing mixing roller 54 is provided with a plurality of stirring rods 542, which are located in the stuffing barrel 51, and the ends of the stirring rods 542 are close to the inner wall of the stuffing barrel 51. The stuffing mixing motor 53 is a bidirectional motor which can realize forward and reverse rotation. Put the prepared dumpling stuffing into the stuffing barrel 51, start the stuffing mixing motor 53, and when the stuffing mixing motor 53 rotates forward, the stuffing feeding spiral blade 541 sends the dumpling stuffing at the bottom of the stuffing barrel 51 to the opening and closing part 13 through the discharge pipe 1. If the dumpling stuffing is put into the stuffing barrel 51 for a period of time before During use, the moisture and oil in the dumpling filling will settle to the bottom of the filling barrel 51, causing the dumpling filling at the bottom to have too much moisture, while the dumpling filling at the top will lose moisture and oil, affecting the taste. At this time, the filling motor 53 is controlled to reverse, and the filling feeding spiral blade 541 is reversed, which will not play the role of feeding the filling. The stirring rod 542 can re-stir the dumpling filling in the filling barrel 51 to make its moisture and oil evenly distributed. The filling motor 53 is controlled to rotate forward again, and the re-stirred dumpling filling is sent to the opening and closing part 13 through the discharge pipe 1.

[0025] The skin pressing mechanism 4 includes a skin pressing push rod motor 41, the push rod end of the skin pressing push rod motor 41 is cylindrical, the edge clamping mechanism 8 includes two semicircular ring edge clamping members 81 and two edge clamping motors 82, the upper surface of the semicircular ring edge clamping member 81 is wavy, which helps to enhance the adhesion between the dumpling skins when the dumpling skins are clamped, and can increase the beauty of the dumplings after forming. A support member 721 is relatively provided on the top of the support platform 72, and two shaft through holes are provided on the support member 721. The two shaft through holes are located on the same horizontal line, and hinge rods are relatively provided at both ends of the semicircular ring edge clamping member 81. The edge clamping piece 81 and the two side support pieces 721 are rotatably connected through the cooperation of the hinge rod and the shaft through hole. The edge clamping motor 82 is installed on the outer vertical surface of the support piece 721. The rotating shaft of the edge clamping motor 82 is connected to the hinge rod. When the two edge clamping motors 82 rotate, they drive the two semicircular ring edge clamping pieces 81 to flip over and fit close to each other, clamping the two edges of the dumpling skin together to form the dumplings. The upper surfaces of the two semicircular ring edge clamping pieces 81 and the upper surface of the support platform 72 are combined into a circular surface 83, and the circular surface 83 has the same circumference as the lower surface of the end of the push rod.

[0026] The lower surface of the end of the push rod is a plane. When the dumpling pressing push rod motor 41 controls the push rod to move downward, the vertical distance between the lower surface of the push rod and the upper surface of the support 72 is at least 1 mm. The circular surface 83 is a concave arc surface, and the depth of the concave arc surface is 2~3 mm. In this way, the middle of the pressed dumpling wrapper is thicker than the edge. The thicker part in the middle of the dumpling wrapper can effectively withstand the expansion force of the dumpling filling, avoiding the rupture of the middle part of the dumpling due to the expansion of the filling during the cooking process. Moreover, when the dumpling wrapper is folded in half and clamped, the original thinner part of the edge is superimposed to have a moderate thickness, maintaining an appropriate thickness with the middle part, so that the overall dumpling wrapper is thick and uniform, improving the taste.

When the edge clamping mechanism 8 clamps the dumplings, the dumpling feeding motor 62 is started, and the transmission shaft drives the rotating rod 611 to rotate, and the wrapped dumplings are pushed off the support 72 by toggling the impeller 61. A dumpling feeding window 22 is provided at the front of the shell 2 and below the dumpling feeding mechanism 6. A dumpling receiving box 9 is provided in front of the dumpling feeding window 22, and the pushed dumplings fall into the dumpling receiving box 9.

[0028] A control box is provided on the front facade of the shell 2, and a control module is provided in the control box. The control box is connected to a power supply.
