DETAILED DESCRIPTION

[0041] 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 field without creative work are within the scope of protection of the utility model.

[0042] Reference Figure 4 , Figure 5 and Figure 8The utility model provides an embodiment: a fully automatic duck pancake roasting machine, comprising a hollow box 1, a transmission belt 10 and a fixed frame 21, the top left and right sides of the hollow box 1 are connected with transparent feeding cylinders 3, the front side of the transparent feeding cylinder 3 is provided with a scale 4, the rear side of the transparent feeding cylinder 3 is fixedly connected with a fixing frame 5, the top of the left fixing frame 5 is fixedly connected with a servo motor 6, the output end of the servo motor 6 passes through the corresponding fixing frame 5 and is fixedly connected with a first screw rod 7, the inner top of the right fixing frame 5 is rotatably connected with a second screw rod 8, the second screw rod 8 and the outer middle and upper parts of the first screw rod 7 are fixedly connected with pulleys 9, and the two pulleys 9 are connected by The transmission belt 10 is connected for transmission. The second screw rod 8 and the first screw rod 7 are both threadedly connected to a movable column 11 at the middle and lower parts of the outer sides. The bottom end of the movable column 11 is fixedly connected to a baffle 12. The middle part of the top of the hollow box 1 is fixedly connected to a servo motor 15. The output end of the servo motor 15 passes through the hollow box 1 and is fixedly connected to a rotating rod 16. A plurality of stirring rods 17 are fixedly connected to the outer sides of the rotating rod 16 at equal intervals. An adjustment mechanism 2 is provided on the left side of the hollow box 1. Slide blocks 13 are fixedly connected to the left and right sides of the two movable columns 11. A plurality of sliding rods 14 are fixedly connected to the inner tops of the two fixed frames 5. The sliding blocks 13 are slidably connected to the outer walls of the corresponding sliding rods 14 respectively.

[0043] Specifically, driven by the servo motor 6, the first screw rod 7 starts to rotate, and the rotational force is transmitted to the pulley 9 on the first screw rod 7. The rotation of the pulley 9 drives the pulley 9 on the second screw rod 8. The pulley 9 is connected to the transmission belt 10, so the second screw rod 8 also starts to rotate. This series of transmission mechanisms makes the movable column 11 on the first screw rod 7 and the second screw rod 8 move downward on the outside of the slide rod 14. When the baffle 12 at the bottom of the movable column 11 separates from the transparent feed barrel 3, the raw materials in the transparent feed barrel 3 begin to flow into the hollow box 1. By observing the scale 4 on the front side of the transparent feed barrel 3, we can accurately control the input amount of the crust raw materials. This control method ensures the effect of quantitative feeding, making the subsequent roast duck cake processing process more stable and efficient. At this time, the servo motor 15 starts to work, driving the rotating rod 16 to rotate, and the stirring rod 17 outside the rotating rod 16 also rotates to evenly stir and mix the raw materials in the hollow box 1. This automatic mixing process eliminates the steps of manual pre-proportioning, further improves the processing efficiency, and meets the needs of users.

[0044] Reference Figure 3 , Figure 6 and Figure 7The regulating mechanism 2 includes a collecting frame 201 and a telescopic hose 204. The collecting frame 201 is fixedly connected to the lower middle part of the left side of the hollow box 1. A sizing pump 202 is fixedly connected to the left side of the hollow box 1. The input end of the sizing pump 202 is connected to the left side of the hollow box 1. The output end of the sizing pump 202 is connected to a connecting pipe 203. A telescopic rod 205 is fixedly connected to the right side of the top of the connecting pipe 203. A hollow rod 206 is fixedly connected to the left side of the top of the connecting pipe 203. The inside of the hollow rod 206 is connected after thawing. A movable rod 207, a hole 208 is provided on the left side of the movable rod 207, a spring 209 is fixedly connected to the right side of the hole 208, a limit rod 210 is fixedly connected to the left end of the spring 209, a plurality of limit holes 211 are equidistantly provided on the left side of the hollow rod 206, the limit rods 210 are respectively plugged into the corresponding limit holes 211, the movable rod 207 and the top of the telescopic rod 205 are fixedly connected to the same spray pipe 212, and the spray pipe 212 is connected to the connecting pipe 203 through the telescopic hose 204;

[0045] Specifically, when roast duck pancakes of different thicknesses are required, the user can adjust the distance between the spray pipe 212 of the device and the heating roller 20 by pressing the limiting rod 210. Specifically, when the limiting rod 210 is pressed, the spring 209 is squeezed, thereby driving the limiting rod 210 to disengage from the limiting hole 211. In this way, the limiting rod 210 can enter the hole 208, thereby releasing the limit on the movable rod 207. At this time, the user can freely move the spray pipe 212 upward or downward to adjust the distance between the spray pipe 212 and the heating roller 20. When the distance between the spray pipe 212 and the heating roller 20 is too close, the contact area between the slurry sprayed from the spray pipe 212 and the pancake boss will increase accordingly, so that the slurry can more easily form a thick coating on the pancake boss, thereby increasing the thickness of the roast duck pancake. On the contrary, if the distance between the spray pipe 212 and the heating roller 20 is too far, the contact area between the slurry and the pancake boss will be reduced, resulting in a decrease in the thickness of the roast duck pancake. This adjustment function can improve the practicability of the roast duck pancake making device.

[0046] Reference Figure 1 , Figure 2 and Figure 3 The left side of the fixed frame 21 is fixedly connected with a stepper motor 22, the output end of the stepper motor 22 passes through the fixed frame 21 and is fixedly connected with a driving roller 23, the inner front side of the fixed frame 21 is rotatably connected with a driven roller 24, the outer side of the driven roller 24 is provided with a conveyor belt 25, the driven roller 24 is transmission-connected with the driving roller 23 through the conveyor belt 25, the top rear side of the fixed frame 21 is fixedly connected with a scraper 26, the middle and upper part of the left side of the hollow box 1 is fixedly connected with a stepper motor 19, and the output end of the stepper motor 19 is fixedly connected with a heating roller 20;

[0047] Specifically, the driving roller 23 is driven by the stepper motor 22 to rotate, which in turn drives the driven roller 24 to rotate, and the conveyor belt 25 starts to operate through the transmission effect of the conveyor belt 25. The purpose of this process is to convey the processed roast duck cake to the subsequent processing process, and the stepper motor 19 can drive the heating drum 20 to rotate until the roast duck cake on the outer roast duck boss moves to the scraper 26 position, and the scraper 26 can scrape off the processed roast duck cake, thereby improving the practicality of the device.

[0048] Reference Figure 1 and Figure 3 A switch 27 is fixedly connected to the right side of the front end of the hollow box 1. The switch 27 is electrically connected to the sizing pump 202, the servo motor 6, the servo motor 15, the stepper motor 19 and the stepper motor 22 respectively. A protective cover 28 is provided on the outer side of the switch 27. The top of the protective cover 28 is rotatably connected to the front side of the hollow box 1 through a rotating shaft.

[0049] Specifically, the operation of the sizing pump 202, the servo motor 6, the servo motor 15, the stepper motor 19 and the stepper motor 22 can be controlled by the switch 27, and the protective cover 28 can protect the switch 27 from being damaged by external factors.

[0050] Reference Figure 1 , an observation window 18 is provided on the left side of the front end of the hollow box 1, and universal wheels 29 are fixedly connected to the front and rear sides of the bottom of the hollow box 1 and the collecting frame 201;

[0051] Specifically, the internal situation of the hollow box 1 can be conveniently observed through the observation window 18, and raw materials can be added in time when the slurry inside is too little, and the universal wheel 29 can be conveniently moved to the side of the conveying device.

[0052] Working principle: When using the device, first inject different ingredients of roast duck cakes into different transparent feeding barrels 3, and then the servo motor 6 can drive the first screw rod 7 to rotate, and the pulley 9 on the first screw rod 7 will rotate accordingly, and the pulley 9 on the second screw rod 8 will rotate accordingly through the transmission belt 10. At this time, the second screw rod 8 starts to rotate, and the movable columns 11 on the first screw rod 7 and the second screw rod 8 will move downward on the outside of the sliding rod 14 until the baffle 12 at the bottom of the movable column 11 is separated from the transparent feeding barrel 3. At this time, the raw materials in the transparent feeding barrel 3 will enter the hollow box 1, and the scale 4 on the front side of the transparent feeding barrel 3 can be observed to control The amount of raw materials for making the crust can be adjusted, so that the effect of quantitative feeding can be achieved. At this time, the servo motor 15 can drive the rotating rod 16 to rotate, and the stirring rod 17 outside the rotating rod 16 will rotate accordingly to stir and mix the raw materials in the hollow box 1, without the need for manual proportioning work in advance, thereby improving the subsequent processing efficiency of roast duck cakes and meeting the needs of users. The heating roller 20 can be heated by gas. Since it is a prior art, it is not described in detail in the text. When the heating roller 20 is heated to a certain temperature, the stepping motor 19 and the sizing pump 202 are started, and the sizing pump 202 can pass through the spray pipe 212 The prepared slurry in the hollow box 1 is sprayed onto the pancake boss on the surface of the heating roller 20, and the stepper motor 19 can drive the heating roller 20 to rotate so that the pancake boss on its outer side can be sprayed with the slurry. Since the surface temperature of the heating roller 20 is relatively high, the slurry sprayed onto the pancake boss can be quickly formed. When the formed pancake boss rotates to the position of the scraper 26, the scraper 26 will scrape it off. At this time, the stepper motor 22 can drive the active roller 23 to rotate, and the driven roller 24 rotates accordingly through the conveyor belt 25, so that the conveyor belt 25 can start to operate, and the processed roast duck cakes can be transported to the subsequent processing flow. When it is not needed, When the thickness of the duck cake is the same, the limit rod 210 can be pressed at this time, and the extrusion force exerted on the spring 209 will drive the limit rod 210 to disengage from the limit hole 211 and enter the hole 208, so that the limit on the movable rod 207 can be released. At this time, the spray pipe 212 can be moved upward or downward to adjust the distance between the spray pipe 212 and the heating roller 20. When the distance between the spray pipe 212 and the heating roller 20 is too close, the slurry sprayed from the spray pipe 212 will have more contact with the cake boss, thereby increasing the thickness of the duck cake, and vice versa, reducing the thickness of the duck cake, thereby improving the practicality of the device.
