[0038] In recent years, the popularity of food cooking appliances has been increasing, and many cooking appliances with different uses have emerged in the market. For example, existing pancake machines have processes such as feeding, dough kneading, pancake pressing, and heating, so as to be able to make pancake dough. However, during the pancake-making process of existing pancake machines, it is not possible to ensure uniform powder feeding for the powder material, and the error in the powder supply of existing pancake machines within the same time period is relatively large, resulting in relatively large differences in the dough made by the dough kneading mechanism, thus affecting the processes of pancake pressing and heating, and ultimately affecting the quality of the pancake.

[0039] The present invention provides a pancake machine with uniform powder feeding, which can solve the problem that existing pancake machines cannot feed powder uniformly and affect the quality of pancakes.

[0040] Please refer to Figures 1 to 4 , the pancake machine with uniform powder feeding of the present invention includes a powder feeding mechanism 10.

A plurality of first material discharging openings 110 are formed at the lower end of the powder storage cup 100; the stirring member 200 is rotatably arranged in the powder storage cup 100; the powder supporting tray 300 is located at the bottom of the powder storage cup 100 and encloses a containing cavity 310 with the powder storage cup 100. The containing cavity 310 is communicated with each of the plurality of first material discharging openings 110. A second material discharging opening 320 communicated with the containing cavity 310 is arranged at the bottom of the powder supporting tray 300. The second material discharging opening 320 and the first material discharging openings 110 are arranged in a vertical offset manner; the metering tray 400 is rotatably arranged in the containing cavity 310. A plurality of vertically penetrating metering holes 410 are arranged on the metering tray 400. The metering holes 410 are used for receiving the powder material falling from the first material discharging openings 110. The plurality of metering holes 410 are sequentially arranged at intervals around the circumference of the metering tray 400. When the metering tray 400 rotates, the plurality of metering holes 410 are sequentially communicated with the second material discharging opening 320.

[0041] It can be understood that the pancake making machine with uniform powder supply further includes a water supply mechanism 20, an oil supply mechanism 30, a dough kneading mechanism 40, a pancake pressing and baking mechanism, and a driving mechanism. The powder supply mechanism 10 is used to supply powder to the dough kneading mechanism 40. The water supply mechanism 20 and the oil supply mechanism 30 are respectively used to supply water and oil to the dough kneading mechanism 40. The dough kneading mechanism 40 is used to uniformly mix the powder, water and oil and stir them into dough. The pancake pressing and baking mechanism is used to press the made dough into a pancake and then heat it until cooked. The driving mechanism is used to provide power to the powder supply mechanism 10, the water supply mechanism 20, the oil supply mechanism 30, the dough kneading structure and the pancake pressing and baking mechanism. Of course, the pancake making machine with quantitative powder supply may further include a pancake pushing mechanism, a pancake receiving mechanism, a heat preservation mechanism, etc., which can be specifically set according to needs and are not limited herein. The main purpose of this application is to solve the problem that the existing pancake making machine cannot supply powder uniformly, and this part will be introduced in detail below.

[0042] The pancake making machine with uniform powder supply further includes a housing, a dough kneading mechanism 40 and a driving mechanism. The powder supply mechanism 10 is installed on the housing, and the dough kneading mechanism 40 is installed inside the housing. The dough kneading mechanism 40 has a dough kneading cavity, and the powder supply mechanism 10 is used to uniformly supply powder into the dough kneading cavity. The metering plate 400 can be driven by the driving mechanism. The driving mechanism includes a driving motor, and the driving motor is installed on the housing to be suitable for driving the metering plate 400 to rotate.

[0043] Further, a plurality of first discharging ports 110 can be provided at the bottom 120 of the powder storage cup 100, or can be provided at the lower end of the side wall of the powder storage cup 100. Of course, they can also be provided at the bottom 120 of the powder storage cup 100 and the lower end of the side wall of the powder storage cup 100 at the same time, which can be specifically set according to needs. In this embodiment, the rotation axis of the metering plate 400 extends in the up and down direction, and a plurality of metering holes 410 are arranged at intervals in the circumferential direction of the metering plate 400 around the metering plate 400. The specific structure of the powder supporting plate 300 is not limited, and only the powder supporting plate 300 and the powder storage cup 100 need to be able to enclose to form a containing cavity 310. In this embodiment, the powder supporting plate 300 includes a powder supporting plate, the powder supporting plate is arranged opposite to the bottom 120 of the powder storage cup 100, and the second discharging port 320 is provided on the powder supporting plate. The second discharging port 320 is arranged offset from the first discharging port 110 in the up and down direction. With such a setting, when the metering plate 400 rotates in the containing cavity 310, the powder can fill the plurality of metering holes 410 in the metering plate 400 and then be discharged into the dough kneading cavity from the second discharging port 320 in sequence, so as to ensure that the powder supply mechanism 10 supplies the powder uniformly. The number of the metering holes 410 is multiple. Specifically, in this embodiment, the number of the metering holes 410 is 24. Of course, in other embodiments, the number of the metering holes 410 is not limited and can be set according to needs.

[0044] Furthermore, a plurality of first material discharging ports 110 are all communicated with the accommodating cavity 310. The metering disc 400 is arranged in the accommodating cavity 310. The metering holes 410 are used for receiving the powder material falling from the first material discharging ports 110. The second material discharging port 320 is communicated with the accommodating cavity 310. When the metering disc 400 rotates, a plurality of metering holes 410 are sequentially communicated with the second material discharging port 320. The first material discharging ports 110 are arranged above at least one of the metering holes 410, and the second material discharging port 320 is arranged below the other metering holes 410. Specifically, in this embodiment, each first material discharging port 110 is arranged directly above at least one of the metering holes 410, and the second material discharging port 320 is arranged directly below the other metering holes 410. In this way, it is convenient for the powder material to smoothly fall into the plurality of metering holes 410 in sequence, and it is also convenient for the powder material in the plurality of metering holes 410 to be discharged from the second material discharging port 320 in sequence when the metering disc 400 rotates.

[0045] The cake making machine for uniformly supplying powder of the present invention includes a powder supply mechanism 10. The powder supply mechanism 10 includes a powder storage cup 100, a stirring member 200, a powder supporting disc 300 and a metering disc 400. A plurality of first material discharging ports 110 are formed at the lower end of the powder storage cup 100. When the powder material is loaded into the powder storage cup 100 and the metering disc 400 rotates, the powder material can fall from the plurality of first material discharging ports 110 into the plurality of metering holes 410 of the metering disc 400, and the plurality of metering holes 410 are filled with the powder material as the metering disc 400 rotates. The second material discharging port 320 is arranged at a dislocation in the up and down direction with respect to the first material discharging ports 110. The plurality of metering holes 410 are sequentially arranged at intervals along the circumferential direction of the metering disc 400. When the metering disc 400 rotates, the plurality of metering holes 410 are sequentially communicated with the second material discharging port 320, so that the powder material in the plurality of metering holes 410 can be discharged from the second material discharging port 320 in sequence, thus realizing the function of uniformly supplying the powder material.

[0046] Please refer to Figure 2 and Figure 3 In one embodiment, the powder storage cup 100 includes a bottom plate, and a plurality of the first material discharging ports 110 are all arranged on the outer peripheral edge of the bottom plate and are sequentially arranged at intervals along the circumferential direction of the bottom plate.

[0047] It can be understood that the stirring member 200 is rotatably disposed in the powder storage cup 100. When the stirring member 200 rotates in the powder storage cup 100, the powder material will move from the central position of the powder storage cup 100 towards the cup wall direction of the powder storage cup 100, that is, the powder material will gather outward. And a plurality of first material discharge ports 110 of the present application are disposed on the outer peripheral edge of the bottom plate of the powder storage cup 100, that is, the first material discharge ports 110 are disposed at the connection between the bottom plate and the cup wall of the powder storage cup 100. In this way, it is beneficial for the powder material gathered at the cup wall to smoothly fall from the first material discharge ports 110 into the metering holes 410 in the accommodating cavity 310, thereby improving the smoothness of the powder material supply. In addition, the plurality of first material discharge ports 110 are sequentially arranged at intervals along the circumferential direction of the bottom plate, which can improve the efficiency of the powder material falling, that is, improve the efficiency of the powder material supply.

[0048] Please refer to Figures 2 to 4 , in an embodiment, the plurality of first material discharge ports 110 include at least one first sub-material discharge port 111. The first sub-material discharge port 111 is disposed on the bottom plate of the powder storage cup 100. The opening width of the first sub-material discharge port 111 along the radial direction of the metering disk 400 is not greater than the opening width of the metering hole 410 along the radial direction of the metering disk 400; the opening length of the first sub-material discharge port 111 along the circumferential direction of the metering disk 400 is not less than the sum of the opening lengths of two adjacent metering holes 410 along the circumferential direction of the metering disk 400, and is not greater than the sum of the opening lengths of four adjacent metering holes 410 along the circumferential direction of the metering disk 400.

[0049] It can be understood that the opening width of the first sub-material discharge port 111 is not greater than the opening width of the metering hole 410, that is, the opening width of the first sub-material discharge port 111 is less than or equal to the opening width of the metering hole 410; and the opening length of the first sub-material discharge port 111 is not less than the sum of the opening lengths of two adjacent metering holes 410, and is not greater than the sum of the opening lengths of four adjacent metering holes 410. With such a setting, when the metering disk 400 rotates, the powder material can smoothly fall from the first material discharge port 110 into the metering hole 410.

[0050] Specifically in this embodiment, the opening width of the first sub-material discharge port 111 is equal to the opening width of the metering hole 410, and the opening length of the first sub-material discharge port 111 is equal to the sum of the opening lengths of three adjacent metering holes 410, that is, the opening area of the first sub-material discharge port 111 is equal to the sum of the opening areas of three adjacent metering holes 410. The opening area of each metering hole 410 is the same, that is, the opening area of the first sub-material discharge port 111 is equivalent to the opening areas of three adjacent grid metering holes 410. In this way, it is beneficial to improve the efficiency and smoothness of the powder material falling.

[0051] In one embodiment, the plurality of the first discharge openings 110 further includes at least one second sub-discharge opening 112. The second sub-discharge opening 112 and the first sub-discharge opening 111 are both disposed on the bottom plate and are sequentially and spaced apart circumferentially around the bottom plate. The opening width of the second sub-discharge opening 112 along the radial direction of the metering disk 400 is not greater than the opening width of the metering hole 410 along the radial direction of the metering disk 400; the opening length of the second sub-discharge opening 112 around the circumferential direction of the metering disk 400 is not less than the opening length of one metering hole 410 around the circumferential direction of the metering disk 400, and is not greater than the sum of the opening lengths of two adjacent metering holes 410 around the circumferential direction of the metering disk 400.

[0052] It can be understood that the opening width of the second sub-discharge opening 112 is not greater than the opening width of the metering hole 410, and the opening length of the second sub-discharge opening 112 is not less than the opening length of one metering hole 410, and is not greater than the sum of the opening lengths of two adjacent metering holes 410. With such a setting, when the metering disk 400 rotates, the powder can smoothly fall from the second discharge opening 320 into the metering hole 410.

[0053] Specifically in this embodiment, the opening width of the second sub-discharge opening 112 is equal to the opening width of the metering hole 410, and the opening length of the second sub-discharge opening 112 is equal to the opening length of one metering hole 410, that is, the opening area of one second sub-discharge opening 112 is equal to the sum of the opening areas of one metering hole 410, that is, the opening area of the second sub-discharge opening 112 is equivalent to the opening area of one grid of metering holes 410. This is beneficial to improving the smoothness of the powder falling.

[0054] In addition, in this embodiment, the number of the first sub-discharge openings 111 is one, and the number of the second sub-discharge openings 112 is two. The two second sub-discharge openings 112 and one first sub-discharge opening 111 are sequentially and spaced apart circumferentially around the bottom plate of the powder storage cup 100, and the distance between adjacent ones is the same. In this way, the plurality of first discharge openings 110 are evenly distributed on the bottom plate, which is beneficial to improving the uniformity and efficiency of the powder falling.

[0055] Please refer to Figure 3 、 Figure 4 、 Figure 10 and Figure 11 , in one embodiment, there is a metering partition 420 between two adjacent metering holes 410. The metering partition 420 is provided with a groove, and the notch of the groove faces the side of the second discharge opening 320.

[0056] It can be understood that by providing the groove, it is beneficial to reduce the weight of the metering disk 400, thereby facilitating the smooth rotation of the metering disk 400. Moreover, the groove extends along the length direction of the metering partition 420, and the notch of the groove is opened towards the side of the second discharge port 320, that is, the notch of the groove is opened in the direction away from the first discharge port 110. In this way, the problem that the powder falls into the groove from the first discharge port 110 and accumulates, resulting in powder waste, is avoided. Furthermore, the powder can be fully utilized, improving the practicality of the metering disk 400.

[0057] Please refer to Figure 2 、 Figure 5 and Figure 6 , in an embodiment, the powder storage cup 100 includes a cup body and a cup bottom 120, the first discharge port 110 is provided on the cup bottom 120, and the stirring member 200 is provided above the cup bottom 120. With such a setting, when the powder is loaded into the powder storage cup 100, the powder can be carried on the cup bottom 120, and the stirring member 200 is provided above the cup bottom 120. As the stirring member 200 rotates, the powder easily falls from the first discharge port 110 into the metering holes 410 in the accommodating cavity 310.

[0058] Please refer to Figure 5 、 Figure 6 and Figure 8 , in an embodiment, the metering disk 400 passes through the cup bottom 120 and is connected to the stirring member 200, so that the stirring member 200 and the metering disk 400 are rotatably arranged in the powder storage cup 100 synchronously. It can be understood that there are various ways to connect the metering disk 400 and the stirring member 200, for example, but not limited to: the metering disk 400 and the stirring member 200 are snap-connected, or connected by a connecting member. The stirring member 200 and the metering disk 400 are rotatably arranged in the powder storage cup 100 synchronously. With such a setting, the way to drive the rotation of the metering disk 400 and the stirring member 200 is simple. One driving mechanism can be used to drive the metering disk 400 and the stirring member 200 to rotate synchronously. In this way, it is beneficial to simplify the structure of the cake making machine. The driving mechanism can include a driving motor and a reducer. Of course, it can also be other drivers, which are not limited here.

[0059] Please refer to Figure 2 、 Figure 3 and Figure 7 , in an embodiment, the stirring member 200 includes multiple groups of powder scraping plates 210, and the multiple groups of powder scraping plates 210 are arranged radially around the rotation center of the stirring member 200.

[0060] It can be understood that the stirring member 200 is disposed in the powder storage cup 100. The stirring member 200 can be in contact with the bottom 120 of the powder storage cup 100. Of course, there can also be a gap between the stirring member 200 and the bottom 120 of the powder storage cup 100, which is not specifically limited herein. And the rotation speed of the stirring member 200 is not limited, as long as the stirring member 200 can scrape the powder into the first discharge port 110. The stirring member 200 is rotatably disposed in the powder storage cup 100. A plurality of first discharge ports 110 are formed at the lower end of the powder storage cup 100. The stirring member 200 includes multiple groups of powder scraping plates 210, and the multiple groups of powder scraping plates 210 are arranged radially. This is beneficial to improving the efficiency of the stirring member 200 scraping the powder into the first discharge port 110, that is, improving the efficiency of the powder falling to the plurality of metering holes 410. In this embodiment, the number of the first discharge ports 110 is three. Correspondingly, the stirring member 200 includes three groups of powder scraping plates 210. When the stirring member 200 rotates, the three groups of powder scraping plates 210 can scrape the powder into the three groups of first discharge ports 110, thus improving the efficiency of the powder falling.

[0061] Please refer to Figures 4 to 7 , in one embodiment, the powder scraping plate 210 includes a powder supporting scraping plate 211 and a cup wall scraping plate 212. The powder supporting scraping plate 211 extends from a position close to the rotation center of the stirring member 200 in the radial direction of the rotation center of the stirring member 200 towards the cup wall direction of the powder storage cup 100. The cup wall scraping plate 212 is connected to one end of the powder supporting scraping plate 211 away from the rotation center and has a gap with the cup wall of the powder storage cup 100. The cup wall scraping plate 212 extends along the cup wall of the powder storage cup 100 in the upward direction.

[0062] It can be understood that the shape of the powder supporting scraping plate 211 of the powder scraping plate 210 can be various. For example, the powder supporting scraping plate 211 can be arranged in a long strip straight shape, and of course, it can also be arranged in a long strip arc shape, which is not specifically limited herein. The cup wall scraping plate 212 extends along the cup wall direction of the powder storage cup 100, so that when the powder scraping plate 210 rotates, the cup wall scraping plate 212 can scrape the powder remaining on the cup wall of the powder storage cup 100. In this way, the powder is fully utilized, and the problem of waste caused by the remaining powder is avoided. Among them, the shape of the cup wall scraping plate 212 is adapted to the shape of the cup wall of the powder storage cup 100.

[0063] When multiple sets of powder scraping plates 210 rotate, the powder supporting scraping plate 211 rotates in the powder supply cavity of the powder storage cup 100. The powder supporting scraping plate 211 can not only scrape the powder in the powder supply cavity of the powder storage cup 100 into the first blanking port 110, but also support the powder in the powder storage cup 100. If the powder cannot fall evenly into the first blanking port 110, it will cause inconsistent compactness of the powder in the metering hole 410. In this application, the powder is supported by the powder supporting scraping plate 211, which can ensure that the compactness of the powder falling into the metering hole 410 is consistent, thus avoiding the problem that the cake making machine cannot supply powder evenly. In addition, the cup wall scraping plate 212 can also rotate around the cup wall of the powder storage cup 100, so as to scrape the residual powder on the cup wall of the powder storage cup 100 into the first blanking port 110, so that the powder in the powder storage cup 100 can be fully utilized, and the problem of powder waste is avoided.

[0064] Please refer to Figure 5 and Figure 6 , in an embodiment, the powder storage cup 100 includes a cup bottom 120, a first annular cup body 130, a second annular cup body 140 and a third annular cup body 150 connected in sequence. The inner diameter of the third annular cup body 150 is greater than the inner diameter of the first annular cup body 130, and the inner diameter of the second annular cup body 140 is tapered from top to bottom; the cup wall scraping plate 212 includes a first sub-scraping plate 213 for scraping powder on the first annular cup body 130 and a second sub-scraping plate 214 for scraping powder on the second annular cup body 140. The powder supporting scraping plate 211, the first sub-scraping plate 213 and the second sub-scraping plate 214 are connected in sequence. There is a gap between the second sub-scraping plate 214 and the inner wall of the second annular cup body 140, and the distance between the second sub-scraping plate 214 and the rotation center is tapered from top to bottom.

[0065] It can be understood that the inner diameter of the third annular cup body 150 is greater than the inner diameter of the first annular cup body 130, that is, the inner diameter of the upper part of the powder storage cup 100 is greater than the inner diameter of the lower part, so that the powder storage space of the powder storage cup 100 is increased without increasing the height. The cup wall scraping plate 212 includes a first sub-scraping plate 213 and a second sub-scraping plate 214. The shape of the first sub-scraping plate 213 is adapted to the shape of the first annular cup body 130, and the shape of the second sub-scraping plate 214 is adapted to the shape of the second annular cup body 140, which is beneficial to improving the powder scraping effect of the cup wall scraping plate 212, so as to ensure that the residual powder on the cup wall of the powder storage cup 100 can be effectively scraped off.

[0066] Furthermore, in this embodiment, the first annular cup body 130 and the third annular cup body 150 are arranged in a straight cylinder shape, which is conducive to the falling of the powder material. The second annular cup body 140 connects the first annular cup body 130 and the third annular cup body 150, and the inner diameter of the second annular cup body 140 is tapered from top to bottom. Correspondingly, the distance between the second sub-scraper 214 and the rotation center of the powder scraping plate 210 is also tapered from top to bottom, that is, the shape of the second sub-scraper 214 is adapted to the shape of the second annular cup body 140. In this way, the reliability of the second sub-scraper 214 to scrape off the residual powder material on the second annular cup body 140 is improved.

[0067] Furthermore, there is a gap between the second sub-scraper 214 and the inner wall of the second annular cup body 140, which is conducive to improving the smoothness of the rotation of the powder scraping plate 210. It can be understood that the gap between the second sub-scraper 214 and the second annular cup body 140 will not be too large to affect the powder scraping effect of the second sub-scraper 214. Optionally, the gap between the second sub-scraper 214 and the second annular cup body 140 is not less than 0.5 mm and not more than 3 mm. With such a setting, while not affecting the smoothness of the rotation of the second sub-scraper 214, the powder scraping effect of the second sub-scraper 214 can be ensured.

[0068] In one embodiment, the first material discharge port 110 is provided at the connection between the cup bottom 120 and the first annular cup body 130. It can be understood that the connection between the cup bottom 120 and the first annular cup body 130 is the peripheral edge of the bottom plate of the cup bottom 120. The bottom plate of the cup bottom 120 is circularly arranged. When the powder scraping plate 210 rotates, the powder material in the powder storage cup 100 is dialed outward by the powder scraping plate 210, and the powder material is easily fallen into the first material discharge port 110 at the peripheral edge of the bottom plate of the cup bottom 120. In this way, it is conducive to improving the smoothness of the powder material falling into the first material discharge port 110.

[0069] In one embodiment, the gap between the cup wall scraper 212 and the cup wall of the powder storage cup 100 is not less than 0.5 mm and not more than 3 mm. With such a setting, the cup wall scraper 212 can rotate smoothly in the powder storage cup 100, and the effect of the cup wall scraper 212 scraping the cup wall of the powder storage cup 100 is ensured, avoiding the problem of powder waste caused by the residual powder material on the cup wall of the powder storage cup 100, thereby improving the practicability of the cake making machine with uniform powder supply.

[0070] In one embodiment, an avoidance surface is formed on the powder scraping plate 210. The avoidance surface is located at the connection between the powder supporting scraping plate 211 and the cup wall scraping plate 212 and on the outer surface of the bottom 120 of the powder storage cup 100 facing the bottom 120 side. The avoidance surface is arranged at an interval in the vertical direction from the upper edge of the first material outlet 110. It can be understood that the avoidance surface is used to avoid the edge of the first material outlet 110 to ensure the smooth rotation of the powder scraping plate 210 in the powder storage cup 100. The avoidance surface is arranged at an interval in the vertical direction from the upper edge of the first material outlet 110, so that there is always a gap in the vertical direction between the avoidance surface and the upper edge of the first material outlet 110 when the powder scraping plate 210 rotates. In this way, the situation that the powder scraping plate 210 shakes and collides with the edge of the first material outlet 110 during rotation is avoided, thereby improving the reliability of the powder scraping plate 210.

[0071] In one embodiment, the bottom 120 of the powder storage cup 100 is arranged in a plane. There is a gap between the avoidance surface and the bottom 120 of the powder storage cup 100. The avoidance surface extends obliquely upward along the rotation direction of the powder scraping plate 210. With such a setting, that is, the avoidance surface is arranged as an inclined surface, and the avoidance surface is inclined upward along the rotation direction of the powder scraping plate 210. The bottom 120 of the powder storage cup 100 is arranged in a plane, that is, the surface of the bottom 120 is a plane. The first material outlet 110 is arranged on the bottom 120. When the powder scraping plate 210 rotates, the inclined avoidance surface will not collide with the edge of the first material outlet 110 on the bottom surface of the bottom 120. In this way, it is beneficial to improve the stability of the stirring member 200 rotating in the powder storage cup 100.

[0072] In one embodiment, the height of the cup wall scraping plate 212 is higher than the height of the powder supporting scraping plate 211. With such a setting, the cup wall scraping plate 212 can scrape off the powder remaining on the cup wall of the powder storage cup 100 above the powder supporting scraping plate 211, so that the powder remaining on the cup wall of the powder storage cup 100 can be fully utilized to avoid the problem of powder waste.

[0073] Please refer to Figures 5 to 7 In one embodiment, the stirring member 200 further includes a powder scraping seat 220. The powder scraping seat 220 is arranged at the central position of the powder storage cup 100. The rotating shaft 510 of the stirring member 200 passes through the powder scraping seat 220. The powder scraping seat 220, the powder supporting scraping plate 211 and the cup wall scraping plate 212 are connected in sequence. The powder scraping seat 220 is fixedly connected to the metering disc 400 so that the metering disc 400 and the stirring member 200 can rotate synchronously.

[0074] It can be understood that a through hole is provided on the bottom 120 of the powder storage cup 100. The metering disk 400 includes a disk body 430 and a connecting column 440. The connecting column 440 is provided on the side of the disk body 430 facing the stirring member 200 and passes through the through hole to be connected to the powder scraping seat 220. A first accommodating groove is provided on the disk body 430 and the connecting column 440. The notch of the first accommodating groove is opened toward the side away from the stirring member 200. The top end of the connecting column 440 away from the disk body 430 is closed, so as to avoid the problem that the powder falls into the first accommodating groove and accumulates, resulting in waste of the powder. Moreover, by fixedly connecting the connecting column 440 of the metering disk 400 with the powder scraping seat 220, the metering disk 400 and the stirring member 200 can rotate synchronously, thereby optimizing the structure of the powder supply mechanism 10. Only by driving the metering disk 400 to rotate by the driving mechanism can the stirring member 200 be driven to rotate. The first accommodating groove is used for the driving end of the driving mechanism to be inserted, so that it is convenient for the installation of the driving mechanism.

[0075] In one embodiment, the cross-sectional area of the powder scraping seat 220 intercepted along the horizontal direction is gradually reduced from bottom to top. The powder scraping seat 220 can be provided in a convex platform shape. In this embodiment, the powder scraping seat 220 is a smooth convex platform. The cross-sectional area of the powder scraping seat 220 intercepted along the horizontal direction is circular, and the cross-sectional area of the powder scraping seat 220 intercepted along the horizontal direction is gradually reduced from bottom to top. When the powder falls onto the powder scraping seat 220, the powder is easy to slide off the powder scraping seat 220, so as to avoid the problem that the powder accumulates on the powder scraping seat 220 and causes waste of the powder.

[0076] In one embodiment, a clamping portion is provided on the outer peripheral wall of the connecting column 440. A second accommodating groove is provided on the powder scraping seat 220. The notch of the second accommodating groove is arranged toward the bottom 120 of the powder storage cup 100. A matching portion adapted to the clamping portion is provided on the groove wall of the second accommodating groove. The clamping portion is in snap-fit connection with the matching portion. Such a setting facilitates the rapid installation of the metering disk 400 and the stirring member 200 and is beneficial to improving the installation efficiency. In this embodiment, a plurality of outer surfaces are provided on the outer peripheral wall of the connecting column 440. The plurality of outer surfaces can be flat surfaces or curved surfaces, as long as the plurality of outer surfaces are not coplanar. Correspondingly, the groove wall of the second accommodating groove includes a plurality of inner wall surfaces adapted to the plurality of outer surfaces. Each outer surface is arranged in one-to-one correspondence with each inner wall surface, that is, the clamping portion includes a plurality of non-coplanar outer surfaces, and the matching portion includes a plurality of non-coplanar inner surfaces, so that the clamping portion can be in snap-fit connection with the matching portion. Specifically, in this embodiment, the connecting column 440 is provided in a hexagonal prism shape. Correspondingly, the matching portion includes six inner wall surfaces, so that it is convenient for the rapid installation of the metering disk 400 and the stirring member 200.

[0077] In one embodiment, an annular groove is provided on the powder scraping seat 220, and the notch of the annular groove faces the bottom 120 of the powder storage cup 100. The annular groove is arranged outside the second accommodating groove. It can be understood that

[0078] It can be understood that by providing the annular groove, it is beneficial to reduce the weight of the powder scraping seat 220. At the same time, the notch of the annular groove is arranged downward, avoiding the problem that the powder falls into the annular groove and accumulates, resulting in waste of the powder. Furthermore, the smoothness of the rotation of the stirring member 200 in the powder storage cup 100 is improved, as well as the applicability of the stirring member 200.

[0079] Please refer to Figure 4 、 Figure 8 and Figure 9 In one embodiment, the powder supply mechanism 10 further includes a runner 500. The runner 500 is rotatably arranged in the accommodating cavity 310. The runner 500 is arranged above the second blanking port 320. The metering hole 410 has an upper opening. Part of the runner 500 extends into the metering hole 410 from the upper opening. The runner 500 can rotate with the rotation of the metering disk 400.

[0080] It can be understood that the runner 500 is rotatably arranged in the accommodating cavity 310 and can rotate with the rotation of the metering disk 400, that is, when the metering disk 400 rotates, it can drive the runner 500 to rotate. The metering hole 410 has an upper opening close to the first blanking port 110 and a lower opening close to the second blanking port 320. Part of the runner 500 extends into the metering hole 410 from the upper opening. That is, when the runner 500 rotates with the rotation of the metering disk 400, the rotation can push the quantitatively metered powder in the metering hole 410 from the upper opening towards the lower opening. At the same time, a plurality of metering holes 410 are sequentially communicated with the second blanking port 320, so that the powder in the plurality of metering holes 410 can be discharged from the second blanking port 320 in sequence, thus realizing the quantitative supply of the powder.

[0081] Please refer to Figure 4 、 Figure 10 and Figure 11 In one embodiment, an installation part is provided at the bottom of the powder storage cup 100. The runner 500 is rotatably arranged on the installation part of the powder storage cup 100. The runner 500 includes a rotating shaft 510. The installation part is provided with an installation groove with an opening facing downward. A shaft hole 160 is provided on the groove wall of the installation groove. The rotating shaft 510 is arranged in the installation groove and is rotatably connected to the shaft hole 160. The axial direction of the rotating shaft 510 is arranged along the radial direction of the metering disk 400.

[0082] It can be understood that the rotating wheel 500 is rotatably arranged at the bottom 120 of the powder storage cup 100, and the installation part is used for installing the rotating wheel 500. The rotating wheel 500 is arranged at the bottom 120 of the powder storage cup 100 and is located in the accommodating groove, so that the powder storage cup 100 and the powder supporting tray 300 can protect the rotating wheel 500, and the rotating wheel 500 is not easily damaged. Thus, it is beneficial to improve the rotation stability of the rotating wheel 500.

[0083] Furthermore, in order to improve the installation stability of the rotating shaft 510, both ends of the rotating shaft 510 can be installed on the groove walls of the installation groove. Specifically, in this embodiment, the installation groove has a first groove wall and a second groove wall that are distributed inside and outside along the radial direction of the metering disk 400. A first shaft hole 160 is provided on the first groove wall, and a second shaft hole 160 is provided on the second groove wall. Both ends of the rotating shaft 510 are respectively arranged in the first shaft hole 160 and the second shaft hole 160. The connection line between the first shaft hole 160 and the second shaft hole 160 is arranged along the radial direction of the metering disk 400, so that the axial direction of the rotating shaft 510 is arranged along the radial direction of the metering disk 400. The metering disk 400 is a disk, and the connection lines of multiple metering holes 410 are arranged in a circular shape on the metering disk 400. The distances between multiple metering holes 410 and the rotation center of the metering disk 400 are all the same. A part of the rotating wheel 500 extends into the metering hole 410 from the upper opening of the metering hole 410. When the metering disk 400 rotates around its axial direction and drives the rotating wheel 500 to rotate, the axial direction of the rotating wheel 500 is arranged along the radial direction of the metering disk 400, so that the rotating wheel 500 can sequentially extend into multiple metering holes 410, and the adaptability between the rotation position of the rotating wheel 500 and the positions of multiple metering holes 410 is better, thereby ensuring that the rotating wheel 500 can sequentially push out the metered powder in multiple metering holes 410.

[0084] In one embodiment, the rotating wheel 500 further includes a plurality of pushing parts 520 arranged on the outer peripheral wall of the rotating shaft 510. The plurality of pushing parts 520 are sequentially arranged at intervals around the circumferential direction of the rotating shaft 510. The pushing parts 520 of the rotating wheel 500 are in meshing transmission with the metering holes 410 of the metering disk 400, and the pushing parts 520 are used to push out the powder in the metering holes 410 from the second material discharging port 320.

[0085] It can be understood that the adjacent two pushing parts 520 are circumferentially spaced around the rotating shaft 510, the adjacent two metering holes 410 are circumferentially spaced around the metering disk 400, and the distance between the adjacent two metering holes 410 is adapted to the distance between the adjacent two pushing parts 520. The pushing part 520 of the rotating wheel 500 is in meshing transmission with the metering hole 410 of the metering disk 400, that is, it is equivalent to that the metering hole 410 of the metering disk 400 is used for the pushing part 520 to be inserted and accommodated, so that the metering disk 400 can drive the rotating wheel 500 to rotate when rotating. During the process of the metering disk 400 driving the rotating wheel 500 to rotate, the pushing part 520 will be inserted into the metering hole 410, so as to be able to push out the metered powder in the metering hole 410. In this way, the method of pushing out the metered powder in the metering hole 410 is simple, which is beneficial to simplifying the structure of the powder supply mechanism 10.

[0086] In one embodiment, the shape of the pushing part 520 is adapted to the shape of the metering hole 410, and the outer contour of the pushing part 520 is arranged in a gradually expanding manner from a position close to the center of the metering disk 400 towards the edge of the metering disk 400. Such a setting makes the overall volume of the pushing part 520 larger, which is beneficial to increasing the contact area between the pushing part 520 and the powder in the metering hole 410, and thus it is easy to push out the powder in the metering hole 410.

[0087] Please refer to Figure 4 、 Figure 11 and Figure 12 In one embodiment, the pushing part 520 includes a first push plate 521 and a second push plate 522 connected to the rotating shaft 510. The length directions of the first push plate 521 and the second push plate 522 are both arranged along the axial direction of the rotating shaft 510. The connection position of the first push plate 521 connected to the rotating shaft 510 is the same as the connection position of the second push plate 522 connected to the rotating shaft 510. One end of the first push plate 521 far from the rotating shaft 510 is spaced from one end of the second push plate 522 far from the rotating shaft 510, so as to form an included angle between the first push plate 521 and the second push plate 522.

[0088] It can be understood that the formation of an included angle between the first push plate 521 and the second push plate 522 is beneficial to increasing the overall volume of the pushing part 520; this included angle can be an obtuse angle, or a right angle, or an acute angle. In this embodiment, the included angle formed between the first push plate 521 and the second push plate 522 is an acute angle; at the same time, both the first push plate 521 and the second push plate 522 are arc-shaped. When the pushing part 520 pushes down the powder in the metering hole 410, the arc-shaped first push plate 521 and second push plate 522 are beneficial to increasing the contact area with the powder in the metering hole 410, so that the powder in the metering hole 410 is easy to be pushed out.

[0089] In one embodiment, the pushing portion 520 further includes a third push plate 523 and a fourth push plate 524. The length direction of the third push plate 523 and the thickness direction of the fourth push plate 524 are both arranged along the axial direction of the rotating shaft 510. The fourth push plate 524 is connected to the first push plate 521 and the second push plate 522. The third push plate 523 is connected to one end of the second push plate 522 away from the rotating shaft 510 and the fourth push plate 524. The first push plate 521, the second push plate 522, the third push plate 523 and the fourth push plate 524 jointly enclose a material pushing groove 525.

[0090] It can be understood that the third push plate 523 is arranged at one end of the second push plate 522 away from the rotating shaft 510. By providing the third push plate 523, it is beneficial to increase the contact area between the pushing portion 520 and the powder in the metering hole 410, so that the powder in the metering hole 410 is easily pushed out. At the same time, it is also beneficial to increase the contact area between the pushing portion 520 and the hole wall of the metering hole 410 during rotation, that is, it is beneficial to increase the contact area between the pushing portion 520 and the metering disk 400, so that the metering disk 400 can easily drive the rotating wheel 500 to rotate.

[0091] Furthermore, by providing the fourth push plate 524, the thickness direction of the fourth push plate 524 is arranged along the axial direction of the rotating shaft 510. In this way, it is beneficial to improve the overall strength of the pushing portion 520. When the pushing portion 520 pushes the powder in the metering hole 410, the notch of the material pushing groove 525 faces the second blanking port 320, and the edge of the notch of the material pushing groove 525 is easy to completely push out the metered powder in the metering hole 410, thus ensuring the stability of the pushing portion 520 to push out the metered powder.

[0092] In one embodiment, the rotating wheel 500 is arranged directly above the second blanking port 320, and the second blanking port 320 is located directly below the metering hole 410. Such an arrangement enables the rotating wheel 500 to quickly and smoothly push the metered powder in the metering hole 410 to the second blanking port 320, that is, it is beneficial to improve the efficiency and smoothness of the powder supply mechanism 10 for supplying powder.

[0093] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
