Technical Field

[0001] The invention relates to the technical field of food processing, in particular to food hand-grabbed pancake forming equipment, a transmission pressing component and a pressing method. Background Art

[0002] Hand-pulled pancake evolved from scallion-pulled pancake. Freshly baked hand-pulled pancakes have thousands of layers, as thin as paper towels. When you pull the pancake with your hands, the dough is connected in thousands of strands. The outer layer is golden and crispy, while the inner layer is soft and tender. The aroma of scallion oil and gluten is tangy.

[0003] A dough pressing and forming device for making hand-pulled pancakes with Chinese patent application number 202210379107.6 includes a base plate, a slide rail, a lifting frame, a pressure plate, a first support spring, a fixed plate, a feeding mechanism and a unloading mechanism. The front side of the top of the base plate is connected to the slide rail, the lifting frame is slidably connected to one side of the slide rail, the bottom of the lifting frame is connected to the pressure plate, the first support spring is connected between the slide rail and the lifting frame, the middle of the top of the base plate is connected to the fixed plate, and the top of the base plate is connected to the feeding mechanism. However, during use, the device cannot adjust the processing of the equipment in time according to the hardness of the dough, which can easily affect the processing effect of the equipment.

[0004] The hand-pulled pancake forming device with Chinese patent application number 202020795653.4 includes a frame, a dough conveying device is installed on the frame, and a cake pressing device cooperating with the dough conveying device is installed on the frame; the cake pressing device includes a bracket installed on the frame and located above the dough conveying device, a guide rod assembly consistent with the conveying direction of the dough conveying device is installed on the bracket, a sliding frame is slidably installed on the guide rod assembly, and buffer devices are installed on the guide rod assemblies on both sides of the sliding frame, but the device cannot adjust the processing of the equipment in time according to the hardness of the dough, which is easy to affect the processing effect of the equipment.

[0005] At the same time, in the process of processing food hand-pulled pancakes, when the dough is pressed into dough sheets only by the action of the main extrusion wheel and the auxiliary extrusion wheel, the effect is poor, and it is often necessary to add a transmission pressing component to the transmission equipment to perform auxiliary extrusion processing of the dough sheets. When the dough sheets are subjected to auxiliary extrusion processing, the dough sheets are prone to being too hard or too soft. When the dough sheets are too hard, it indicates that there is less moisture in the dough sheets, and when the dough sheets are too soft, it indicates that there is more moisture in the dough sheets. Both of these will affect the processing effect of the food hand-pulled pancakes. In addition, when the transmission pressing component performs auxiliary extrusion processing of the dough sheets, the dough sheets are prone to adhere to the transmission pressing component, thereby affecting the processing effect.

The dough sheets on the discharge plate 6 will fall on the transmission device 3 for transportation, so that the dough sheets are conveyed to the next process for processing and forming the food hand-grabbed pancake.

[0036] The extrusion device 4 includes a first circular shaft 401, a second circular shaft 402 and a third circular shaft 403, the first circular shaft 401 and the third circular shaft 403 are rotatably arranged between the two mounting side plates 2, a main extrusion wheel 404 is arranged on the first circular shaft 401, an auxiliary conveying wheel 405 is arranged on the third circular shaft 403, a limiting slide groove 406 is arranged on the side where the two mounting side plates 2 are close to each other, the second circular shaft 402 is arranged in the limiting slide groove 406, an auxiliary extrusion wheel 407 is rotatably arranged on the second circular shaft 402, a driven gear 408 is arranged on the first circular shaft 401, a driving gear 409 is arranged on the third circular shaft 403, the driving gear 409 and the driven gear 408 are meshed with each other, and the adjustment device 7 is provided. Placed on the second circular shaft 402, the rotation of the third circular shaft 403 will drive the rotation of the auxiliary conveying wheel 405 and the driving gear 409, and the rotation of the driving gear 409 will drive the rotation of the driven gear 408, thereby rotating the first circular shaft 401. The rotation of the first circular shaft 401 will drive the rotation of the main extrusion wheel 404. When the main extrusion wheel 404 rotates, it will extrude the dough entering between the main extrusion wheel 404 and the auxiliary extrusion wheel 407, so that the dough is squeezed into a dough sheet, and the rear sheet is transported to the discharge plate 6 under the action of the auxiliary conveying wheel 405, and the distance between the main extrusion wheel 404 and the auxiliary extrusion wheel 407 can be adjusted with the assistance of the adjustment device 7, thereby adjusting the thickness of the dough sheet.

[0037] A driving device 8 is also arranged between the two mounting side plates 2, and the driving device 8 includes a driving motor 801. A mounting plate 802 is arranged between the two mounting side plates 2 and between the auxiliary conveying wheels 405. The driving motor 801 is arranged on the mounting plate 802. A driving wheel 803 is arranged at the output end of the driving motor 801. A driven wheel is arranged on the third circular shaft 403. A transmission belt 804 is arranged between the driving wheel 803 and the driven wheel. After the driving motor 801 is started, the output end of the driving motor 801 drives the rotation of the driving wheel 803. The rotation of the driving wheel 803 drives the rotation of the driven wheel with the assistance of the transmission belt 804. The rotation of the driven wheel drives the rotation of the third circular shaft 403. The assistance of the driving motor 801 provides power for the rotation of the third circular shaft 403, so that the rotation of the third circular shaft 403 is more stable.

[0038] The adjusting device 7 includes an inclined plate 701, which is arranged between the two mounting side plates 2. A screw 702 is arranged on the inclined plate 701, and the screw 702 is threadedly matched with the inclined plate 701. One end of the screw 702 is rotatably arranged on the second circular shaft 402, and a turntable 703 is arranged on the other end of the screw 702. The turntable 703 is rotated, and the rotation of the turntable 703 drives the rotation of the screw 702. The rotation of the screw 702 is threadedly matched with the inclined plate 701, so that the second circular shaft 402 slides in the limiting slide groove 406, thereby changing the distance between the auxiliary extrusion wheel 407 and the main extrusion wheel 404, thereby changing the thickness of the extruded dough sheet.

[0039] Limiting plates are provided at the side ends of the feed plate 5 and the discharge plate 6, the lower end of the feed plate 5 is aligned between the main extrusion wheel 404 and the auxiliary extrusion wheel 407, the upper end of the discharge plate 6 is located at the lower end of the auxiliary conveying wheel 405, and the lower end of the discharge plate 6 is located at the upper end of the transmission device 3. The dough on the feed plate 5 is limited by the limiting plate when sliding down, and the dough sheet on the discharge plate 6 is limited by the limiting plate when sliding down, so that the production of hand-pulled pancakes is more stable.

[0040] The transmission device 3 includes two mounting frames 301, and the mounting frames 301 are arranged at the side ends of the mounting side plates 2. A disc 302 is rotatably arranged on the side where the two mounting frames 301 are close to each other. A plurality of round rods 303 are arranged on the side where the two discs 302 are close to each other. The two discs 302 between the two mounting frames 301 and the plurality of round rods 303 between the two discs 302 form a transmission group. Two transmission groups are arranged between the two mounting frames 301, and transmission belts 304 are arranged on the two transmission groups. A motor for driving the disc 302 to rotate is also arranged at the side ends of the mounting frames 301. When the motor is started, the motor drives the disc 302 to rotate. The rotation of the disc 302 causes the plurality of round rods 303 to rotate, thereby causing the transmission belt 304 to rotate in a cycle. The circular rotation of the transmission belt 304 drives the dough sheet thereon to move, so that the dough sheet moves to the next process.

[0041] During use of the present invention, the drive motor 801 is first started, and the output end of the drive motor 801 drives the rotation of the drive wheel 803. The rotation of the drive wheel 803 drives the rotation of the driven wheel through the assistance of the transmission belt 804. The rotation of the driven wheel will drive the rotation of the third circular shaft 403. The rotation of the third circular shaft 403 will drive the rotation of the auxiliary conveying wheel 405 and the driving gear 409. The rotation of the driving gear 409 drives the rotation of the driven gear 408 through meshing transmission. The rotation of the driven gear 408 drives the rotation of the first circular shaft 401, thereby rotating the main extrusion wheel 404.

[0042] Then, the turntable 703 is rotated. The rotation of the turntable 703 drives the rotation of the screw 702. The rotation of the screw 702 is threadedly matched with the inclined plate 701, so that the second circular shaft 402 slides in the limiting slide groove 406, thereby changing the distance between the auxiliary extrusion wheel 407 and the main extrusion wheel 404, thereby changing the thickness of the extruded dough sheet.

[0043] Then the motor is started, and the motor drives the disc 302 to rotate. The rotation of the disc 302 causes the plurality of round rods 303 to rotate, thereby causing the conveyor belt 304 to rotate in a circular manner.

[0044] After the equipment is running stably, the dough for producing hand-pulled pancakes is placed on the feed plate 5, and the dough will gradually slide on the feed plate 5. As the dough slides on the feed plate 5, the dough will enter between the main extrusion wheel 404 and the auxiliary extrusion wheel 407. Due to the rotation of the main extrusion wheel 404, the main extrusion wheel 404 and the auxiliary extrusion wheel 407 cooperate to extrude the dough to form a dough sheet. The dough sheet will pass through the main extrusion wheel 404 and the auxiliary extrusion wheel 407 and fall on the auxiliary conveying wheel 405. As the auxiliary conveying wheel 405 rotates, the dough sheet will fall on the discharge plate 6, and then the dough sheet on the discharge plate 6 will fall on the conveyor belt 304. As the conveyor belt 304 circulates, the conveyor belt 304 moves the dough sheet to the next step for processing.

[0045] In the process of processing food hand-grabbed pancakes, when the dough is pressed into dough sheets only by the action of the main extrusion wheel 404 and the auxiliary extrusion wheel 407, the effect is poor, and it is often necessary to add a transmission and pressing component to the transmission device 3 to perform auxiliary extrusion processing of the dough sheets. When the dough sheets are subjected to auxiliary extrusion processing, the dough sheets are prone to being too hard or too soft. When the dough sheets are too hard, it indicates that there is less moisture in the dough sheets, and when the dough sheets are too soft, it indicates that there is more moisture in the dough sheets. Both of these will affect the processing effect of the food hand-grabbed pancakes. In addition, when the transmission and pressing component performs auxiliary extrusion processing of the dough sheets, the dough sheets are prone to adhere to the transmission and pressing component, thereby affecting its processing effect. Therefore, the present invention also provides a transmission and pressing component of a food hand-grabbed pancake forming device.

[0046] like Figures 1 to 6 As shown, the transmission and pressing assembly of the present invention includes a transmission and pressing part 9, which is arranged at the upper ends of two mounting frames 301. When the dough sheet moves along with the conveyor belt 304, the dough sheet is assisted by the transmission and pressing part 9 to perform auxiliary extrusion processing, so that the thickness of the dough sheet is further thinned.

[0047] The transmission pressing part 9 includes a vertical plate 901, on which a mounting plate 902 is rotatably provided, and a roller 903 is rotatably provided at the side end of the mounting plate 902. A round stick 904 is also provided at the side end of the vertical plate 901, and an electromagnet 905 is provided at the lower end of the round stick 904. A nozzle 906 is provided at the lower end of the round stick 904, and a nozzle 907 is slidably provided in the nozzle 906. A channel 908 is provided in the nozzle 906, and a connection port 909 is provided at the portion of the nozzle 907 located in the channel 908. A limiting groove 910 is provided in the nozzle 906, and the nozzle A slider 911 is provided on 907, and the slider 911 slides in the limiting groove 910. The mounting plate 902 rotates to rotate the multiple rollers 903. During the rotation of the multiple rollers 903, the dough sheet on the conveyor belt 304 is assisted in extrusion to further thin the dough sheet. The nozzle 907 sprays water mist, and the water mist sprayed by the nozzle 907 falls on the roller 903. When the roller 903 rolls and squeezes the dough sheet, the water on the roller 903 enters the dough sheet, thereby replenishing water to the dough sheet to prevent the dough sheet from lacking water and becoming hard.

[0048] A circular hole 912 is provided on the outer side of the roller 903, a plug rod 913 is provided in the circular hole 912, a damping rod 914 is provided between the plug rod 913 and the circular hole 912, the plug rod 913 is magnetic, and a slope is provided at the lower end of the nozzle 907. When the electromagnet 905 is energized, it will generate magnetism, so that the lower end of the electromagnet 905 is N-level, and the plug rod 913 is also magnetic, and the side of the plug rod 913 close to the center of the roller 903 is N-level. Therefore, when the electromagnet 905 is energized, the plug rod 913 on the roller 903 will overcome the resistance of the damping rod 914 and extend from the circular hole 912. At this time, as the roller 903 rolls on the dough sheet, the plug rod 913 will insert a hole into the dough sheet, so that when the dough sheet is too soft, the moisture in the dough sheet can be discharged by inserting a hole into the dough sheet, thereby improving the processing effect of the equipment.

[0049] A leveling roller 10 is provided at the upper end of the mounting frame 301 on the side of the transmission and pressing part 9 away from the dough kneading device 1, and a pressure sensor is provided on the outer side of the leveling roller 10. A support plate 11 is provided in the middle of the conveyor belt 304 between the two mounting frames 301. After the multiple rollers 903 perform auxiliary extrusion processing on the dough sheet, the surface of the dough sheet will appear wavy, and the surface of the dough sheet can be made smooth with the assistance of the leveling roller 10, thereby improving the processing effect of the equipment on the hand-pulled pancake, and the support plate 11 is used to make the auxiliary extrusion of the multiple rollers 903 more stable.

[0050] The side ends of the transmission pressing part 9 and the leveling roller 10 are both provided with motor drive units, and a water pump 12 is also provided on the outside of the mounting frame 301. A connecting pipe 13 is provided at the output end of the water pump 12. The connecting pipe 13 passes through the round stick 904 and is connected to the nozzle 906. After the water pump 12 is started, water will be sent into the connecting pipe 13, and then the water in the connecting pipe 13 will enter the nozzle 906, and then the water in the nozzle 906 can be sprayed out by the nozzle 907.

[0051] During the use of the present invention, the motor drive units at the side ends of the transmission pressing part 9 and the leveling roller 10 are started to rotate the mounting plate 902 and the leveling roller 10. As the conveyor belt 304 moves, the dough sheet on the conveyor belt 304 enters between the roller 903 and the conveyor belt 304. At this time, as the mounting plate 902 rotates, the roller 903 rolls on the dough sheet on the conveyor belt 304, thereby squeezing the dough sheet to further thin the dough sheet. After being processed by the transmission pressing part 9, the surface of the dough sheet becomes wavy, and then the wavy The dough sheet will enter between the leveling roller 10 and the conveyor belt 304. As the leveling roller 10 rotates, the wavy surface of the dough sheet will be leveled, making the hand-pulled pancake processed by the equipment more flat. When the leveling roller 10 is leveling the dough sheet, the detection value of the pressure sensor on the leveling roller 10 will increase, and the detection value of the pressure sensor will be different depending on the hardness of the dough sheet. When the detection value of the pressure sensor is greater than the threshold value, it indicates that the hardness of the dough sheet is greater, and when the detection value of the pressure sensor is less than the threshold value, it indicates that the hardness of the dough sheet is smaller.

[0052] Therefore, when the detection value of the pressure sensor is greater than the threshold value, it indicates that the dough being processed this time contains less water, so the dough produced by the processing has a greater hardness. At this time, the equipment controls the water pump 12 to start. After the water pump 12 is started, water enters the connecting pipe 13. The water in the connecting pipe 13 will enter the channel 908. The water in the channel 908 will pass through the connecting port 909 and enter the nozzle 907. Then the nozzle 907 sprays water mist to act on the roller 903. At this time, as the roller 903 rolls on the dough, the water on the roller 903 will enter the dough, making the dough processed by the transmission and pressing part 9 soften, thereby avoiding the deterioration of the effect of the hand-grabbed pancake produced subsequently.

[0053] After the water pump 12 is started, the water in the channel 908 will act on the nozzle 907, causing the nozzle 907 to move downward and stick to the roller 903. At this time, during the rotation of the roller 903, the nozzle 907 can clean the dough residue adhering to the roller 903, so that the roller 903 remains clean and the roller 903 has a better processing effect on the dough sheet.

[0054] When the detection value of the pressure sensor is greater than the second threshold value, it indicates that the dough being processed this time has too little water, so the hardness of the dough produced by the processing is too large. At this time, the equipment control makes the electromagnet 905 energized. After the electromagnet 905 is energized, it will generate magnetism, so that the lower end of the electromagnet 905 is N level, and the insertion rod 913 is also magnetic, and the side of the insertion rod 913 close to the center of the roller 903 is N level. Therefore, after the electromagnet 905 is energized, the insertion rod 913 on the roller 903 will overcome the resistance of the damping rod 914 and extend from the circular hole 912. At this time, as the roller 903 rolls on the dough, the insertion rod 913 will insert a hole into the dough. After the dough is inserted by the insertion rod 913, the water on the roller 903 can better enter the dough, making the dough soft.

[0055] After the water pump 12 is started and the electromagnet 905 is energized, as the roller 903 rotates, the extended plug rod 913 will act on the lower end of the nozzle 907, causing the nozzle 907 to move upward. After the nozzle 907 moves upward, the connecting port 909 will become larger, so that the amount of water mist sprayed by the nozzle 907 will increase, so that more water mist will act on the roller 903, increasing the hardness of the dough sheet and increasing the amount of water acting on the roller 903, so that the dough sheet can be better processed and softened, thereby improving the processing effect of the equipment.

[0056] When the detection value of the pressure sensor is less than the threshold value, it indicates that the dough being processed this time contains more water, so the hardness of the dough produced by the processing is small. At this time, the equipment controls the water pump 12 to be turned off, and the electromagnet 905 is energized. After the electromagnet 905 is energized, it will generate magnetism, so that the lower end of the electromagnet 905 is N level, and the insertion rod 913 is also magnetic, and the side of the insertion rod 913 close to the center of the roller 903 is N level. Therefore, after the electromagnet 905 is energized, the insertion rod 913 on the roller 903 will overcome the resistance of the damping rod 914 and extend from the circular hole 912. At this time, as the roller 903 rolls on the dough, the insertion rod 913 will insert a hole into the dough, so that when the dough is too soft, the moisture in the dough can be discharged and volatilized by inserting the hole into the dough, thereby increasing the hardness of the dough and improving the processing effect of the equipment.

[0057] The present invention also provides a pressing method of a transmission pressing assembly of a food hand-grabbed pancake forming device, comprising the following steps:

[0058] Step 1: Start the driving motor 801 to rotate the main extrusion wheel 404 and the auxiliary conveying wheel 405, and start the motor to operate the transmission device 3, and at the same time start the motor driving unit at the side end of the transmission pressing part 9 and the leveling roller 10 to rotate the transmission pressing part 9 and the leveling roller 10;

[0059] Step 2: placing the dough on the feed plate 5, the dough is extruded by the main extrusion wheel 404 and the auxiliary conveying wheel 405, and the dough sheet formed by the extrusion is transported by the transmission device 3;

[0060] Step three: the dough sheet transported by the conveying device 3 is further extruded by the conveying and pressing part 9, and then flattened by the flattening roller 10. The processed dough sheet is transported by the conveying device 3 to the next step for further processing to produce hand-pulled pancakes.

[0061] The main functions realized by the present invention are as follows: by setting components such as a water pump 12, an electromagnet 905, a nozzle 907 and an insertion rod 913, when the pressure sensor detects that the hardness of the dough sheet on the conveyor belt 304 is relatively large, the water pump 12 is started, and water mist is sprayed through the nozzle 907 to act on the roller 903. When the roller 903 squeezes the dough sheet, the water on the roller 903 will enter the dough sheet, thereby softening the dough sheet. When the pressure sensor detects that the dough sheet on the conveyor belt 304 is too hard, the water pump 12 is started, and the electromagnet 905 is energized. After the electromagnet 905 is energized, the insertion rod 913 is extended. As the roller 903 squeezes the dough sheet, the insertion rod 913 is extended. Rod 913 inserts holes into the dough sheet to allow water to better blend into the dough sheet, and the insertion of rod 913 will also move nozzle 907 upward to increase the amount of water sprayed from nozzle 907. When the pressure sensor detects that the hardness of the dough sheet on the conveyor belt 304 is too low, the water pump 12 is turned off, and the electromagnet 905 is energized to enable the insertion of rod 913 to insert holes into the dough sheet. When the dough sheet moves with the conveyor device 3, excess water in the dough sheet will be dissipated through the holes. At the same time, during the start-up of the water pump 12, the nozzle 907 is attached to the roller 903. As the roller 903 rotates, the nozzle 907 will clean the dough residue adhered to the roller 903, thereby improving the processing effect of the equipment.
