[0002] Jianbing sold on the street is a food that can be eaten immediately. It is easy to carry and takes a short time to eat, so it is very popular among office workers and students. With the development of technology, automatic Jianbing vending machines have been introduced to the market to realize automated production and sales.

[0003] In the process of making pancakes, after the pancakes are formed and sprinkled with ingredients, the griddle needs to be separated from the dough, so as to facilitate the subsequent folding of the finished pancakes and bagging. Some automatic pancake-making equipment has a spatula for scraping the dough around the griddle. After the pancakes are made, the pancakes are separated from the griddle by the spatula. However, when the spatula scoops up the pancakes, the pancakes are easily adhered to the spatula due to the high temperature of the freshly made pancakes. As the spatula moves and the griddle rotates, the pancakes are easily wrinkled or even broken, affecting the integrity of the pancakes and causing the side dishes to leak out when the side dishes are subsequently placed on the pancakes. Therefore, a spatula for a pancake machine that prevents the pancakes from sticking to the spatula is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a spatula for a pancake machine which is anti-sticky, thereby improving the effect of the spatula on scooping up pancakes, preventing the pancakes from sticking to the spatula, and ensuring the integrity of the pancakes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spatula for a pancake machine that prevents the knife from sticking, comprising a spatula and a rotating drive member for driving the spatula to rotate, a cavity is opened inside the spatula, a rotating groove is opened through the top wall of the cavity, a guide rod is rotatably connected in the rotating groove, a bracket is fixedly connected to the inner wall of the cavity, a gear is rotatably connected to the side wall of the bracket, a tooth groove is opened on the outer wall of one end of the guide rod, the gear is meshed with the tooth groove, a rotating blade is fixedly connected to the outer wall of the gear, a first air pipe and a second air pipe are fixedly connected to the upper surface of the spatula, the first air pipe and the second air pipe both penetrate into the cavity and are connected to the cavity, the first air pipe and the second air pipe are respectively located on both sides of the rotating blade, and the rotating blade is located on the gas path transported by the first air pipe and the second air pipe.

[0006] Preferably, the width of the end of the blade away from the rotating drive member gradually decreases, and the upper blade surface is an arc-shaped surface and the bottom surface is a plane. The thickness in the middle of the upper blade surface is greater than the thickness on both sides of the edge. The maximum angle between the upper blade surface and the plane is a preset angle, and the preset angle is 30°. The end surface of the blade away from the rotating drive member is an arc-shaped structure.

[0007] Preferably, the thickness of one end of the blade away from the rotary drive member is smaller than the thickness of the other end of the blade.

[0008] Preferably, one side edge of the scraper is a straight edge, and the other side edge of the scraper, at one end away from the rotary drive member, is an arc-shaped blade belly.

[0009] Preferably, it also includes a mounting head, one end of the scraper is mounted on the mounting head, and the mounting head is mounted on the rotating drive member through bolts.

[0010] Preferably, the longitudinal projection of the blade is an acute triangle, and the base angle of the blade is greater than 75°.

[0011] Preferably, a fixing groove is provided on one end of the lower blade surface of the scraper close to the mounting head, and an insertion rod is installed in the fixing groove, one end of the insertion rod passes through the mounting head and is connected to the rotating drive member.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model installs a guide rod driven by a starter on the spatula, so that when the spatula scoops up the pancake, the rotating guide rod is used to guide the pancake so that it cannot stick to the spatula, and the gas used to start the guide rod to rotate enters the cavity in the guide rod at the same time to cool the spatula, thereby further avoiding the phenomenon that the pancake sticks to the spatula, so as to facilitate the production of pancakes and ensure the quality of the pancakes.

[0014] 2. The utility model sets the spatula to a structure whose height gradually decreases from the middle to the edges on both sides. When the surface of the griddle is scraped in cooperation with the rotating drive member, the pancake can be easily scraped off the griddle. The width of the spatula gradually decreases toward the tip end, thereby reducing the amount of material under the premise of ensuring a longer spatula and a longer blade surface. At the same time, the maximum angle between the upper blade surface of the spatula and the horizontal plane is limited. While ensuring a good scraping effect, the appropriate height ensures that the pancake is completely scraped off, avoiding the situation where the pancake sticks to the griddle again in a short time or the scraping is incomplete.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-7 The anti-sticking knife pancake machine spatula of this embodiment includes a spatula 1 and a rotating drive member 2 for driving the spatula 1 to rotate. A cavity 6 is opened inside the spatula 1. A rotation groove 4 is opened through the top wall of the cavity 6. A guide rod 5 is rotatably connected in the rotation groove 4. A bracket 9 is fixedly connected to the inner wall of the cavity 6. A gear 10 is rotatably connected to the side wall of the bracket 9. A tooth groove 12 is opened on the outer wall of one end of the guide rod 5. The gear 10 is meshed and connected with the tooth groove 12. A rotary vane 11 is fixedly connected to the outer wall of the gear 10. A first air pipe 7 and a second air pipe 8 are fixedly connected to the upper surface of the spatula 1. The first air pipe 7 and the second air pipe 8 both penetrate into the cavity 6 and are connected with the cavity 6. The first air pipe 7 and the second air pipe 8 are respectively located on both sides of the rotary vane 11. The rotary vane 11 is located on the gas path delivered by the first air pipe 7 and the second air pipe 8.

[0026] like Figure 1 , 2As shown in Figures 3, 6 and 7, the scraper structure in the utility model is similar to the existing scraper structure. The main improvement of the utility model is to improve the effect of the scraper on scooping up the pancakes, so that the pancakes do not stick to the scraper, and the integrity of the pancakes is guaranteed. When the scraper 1 needs to scoop up the pancakes on the griddle, the rotary drive member 2 drives the scraper 1 to tilt, and the scraper 1 moves. The first air pipe 7 and the second air pipe 8 are both connected to the external air pump, and the first air pipe 7 is ventilated first. The gas transported in the first air pipe 7 is transported to the cavity 6, and the rotary blade 11 is blown to make it rotate. The rotary blade 11 drives the gear 10 to rotate on the bracket 9, and the gear 10 drives the guide rod 5 to rotate through the tooth groove 12. At this time, the direction of rotation of the guide rod 5 is opposite to the direction of movement of the scraper 1. The scraper 1 scoops up the pancakes on the griddle, and the pancakes are connected to the outer wall of the guide rod 5. The rotation of the guide rod 5 along with the movement of the spatula 1 can prevent the pancake with higher temperature from sticking to the outer wall of the spatula 1, and the pancake is driven to rotate along with the griddle to completely scoop up the pancake from the griddle. After the pancake is scooped up, the rotating driving member 2 drives the spatula 1 to rotate to a horizontal position. At this time, the spatula 1 moves back and stops ventilating into the first air pipe 7, and ventilates into the second air pipe 8 at the same time, so that the knife rod 8 is reversed until the spatula 1 is separated from the pancake. The gas transported by the first air pipe 7 and the second air pipe 8 to the cavity 6 of the spatula 1 can cool the spatula 1, and further prevent the pancake with too high temperature from sticking to the spatula 1. An air outlet is provided on the bottom surface of the cavity 6, and the gas entering the cavity 6 is discharged from the air outlet, thereby improving the air flow in the cavity 6, thereby improving the heat dissipation of the spatula 1, so as to facilitate the production of pancakes and ensure the quality of the pancakes.

[0027] Among them, the above-mentioned rotating drive component 2 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The rotating drive component 2 is equipped with a power connection line, and it is electrically connected to the external main controller and the 220V phase voltage through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0028] like Figure 1 , 2As shown in Figures 4, 5 and 6, the width of the end of the scraper 1 away from the rotating drive member 2 gradually decreases, and the upper blade surface of the scraper 1 is an arcuate surface and the bottom surface is a plane. The thickness of the middle part of the upper blade surface of the scraper 1 is greater than the thickness of the edges on both sides. The maximum angle between the upper blade surface of the scraper 1 and the plane is a preset angle, which is 30°. The end surface of the scraper 1 away from the rotating drive member 2 is an arc-shaped structure; the upper blade surface of the scraper 1 is a "^"-shaped structure. By setting the scraper 1 to a structure in which the height gradually decreases from the middle to the edges on both sides, the scraper 1 is tilted in conjunction with the rotating drive member 2, and then in conjunction with the rotation of the griddle, the pancake can be easily scooped up from the griddle 2. The width of the scraper 1 gradually decreases toward the tip end, ensuring that a longer scraper 1 reduces the amount of material used, and limiting the maximum angle between the upper blade surface of the scraper 1 and the plane to 30°. While ensuring a good scraping effect, an appropriate height ensures that the pancake is completely scraped off, avoiding the situation where it fits the griddle again in a short time or the scraping is incomplete, thereby improving practicality.

[0029] like Figure 1 , 2 As shown in Figures 4, 5 and 6, the thickness of one end of the scraper 1 away from the rotating drive member 2 is smaller than the thickness of the other end of the scraper 1; the height of the tip side of the scraper 1 is relatively small, and when cutting in, the tip of the scraper 1 can first contact the prepared pancake. The thin thickness of the tip can effectively reduce the difficulty of separating the pancake from the surface of the griddle at the beginning, which is conducive to smooth cutting in. As the contact area between the scraper 1 and the pancake gradually increases, the closer the pancake is to the outer edge, the greater the scraping amplitude and the higher the scraping height. The griddle drives the pancake to rotate, and then gradually and completely shovels the pancake from the griddle, ensuring that the scraper 1 can be inserted between the pancake and the griddle when cutting in.

[0030] like Figure 1 , 2 As shown in Figures 4, one side of the blade 1 is a straight blade, and the other side of the blade 1 is an arc-shaped blade belly away from the rotating drive member 2; the blade of the side of the blade 1 that scoops up the pancake is a straight blade, and the straight blade feed can avoid as much as possible the situation where the pancake moves on the surface of the griddle and deviates from the center of the griddle 2 when scraping the pancake, and can also avoid the subsequent impact on the pancake stacking and bagging process; the other side of the blade 1 is an arc-shaped blade belly, and the arc-shaped structure is not sharp, which can avoid damage to the pancake when the blade 1 is returned.

[0031] like Figure 2 , 4As shown in , 5 and 6, it also includes a mounting head 3, one end of the scraper 1 is mounted on the mounting head 3, and the mounting head 3 is mounted on the rotating drive member 2 by bolts; a fixing groove 13 is provided on the lower blade surface of the scraper 1 close to one end of the mounting head 3, and an insertion rod 14 is installed in the fixing groove 13, one end of the insertion rod 14 passes through the mounting head 3 and is connected to the rotating drive member 2; the scraper 1 is installed on the mounting head 3, which is convenient for installing the scraper 1 on the rotating drive member 2. More specifically, a socket can be provided at the mounting end of the rotating drive member 2, and one end of the insertion rod 14 can be plugged into the socket. The specific fixing method is not limited, which is convenient for disassembly and assembly.

[0032] like Figure 1 , 2 As shown in Figures 4, 5 and 6, the longitudinal projection of the spatula 1 is an acute triangle, and the base angle of the spatula 1 is greater than 75°; on the premise of ensuring a longer spatula 1 and a longer blade surface, the amount of material used is reduced, the cost is reduced, and the pancake is more stable when being scooped up.

[0033] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
