[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 3 shown, a cookie embryo forming device proposed in this embodiment includes a U-shaped support 1. The bottom of the U-shaped support 1 is fixedly connected with six legs in a rectangular shape. The top of the U-shaped support 1 is fixedly connected with a U-shaped plate 4. The right side of the top of the U-shaped plate 4 is fixedly installed with a PLC controller 5. A storage bin 6 with an open top is fixedly connected between the front and rear inner walls of the U-shaped plate 4. The bottom of the storage bin 6 is communicated and fixed with a plurality of forming nozzles 12. The left side of the storage bin 6 is fixedly installed with a recognition camera 11 electrically connected to the PLC controller 5. A conveying assembly electrically connected to the PLC controller 5 is installed in the U-shaped support 1. A cookie tray 100 is in movable contact with the conveying assembly. The conveying assembly is used to convey and automatically stop conveying the cookie tray 100 under the control of the PLC controller 5. When the recognition camera 11 recognizes that the cookie tray 100 enters below the storage bin 6, a stop conveying signal is transmitted to the PLC controller 5;

[0025] An automatic metering and extrusion assembly adapted to the inside of the storage bin 6 is installed on the top inner wall of the U-shaped plate 4. The automatic metering and extrusion assembly is electrically connected to the PLC controller 5. The automatic metering and extrusion assembly is used to automatically extrude the cookie material in the storage bin 6 at the same distance each time under the control of the PLC controller 5, so that the cookie material is quantitatively formed through a plurality of forming nozzles 12 and discharged into the cookie tray 100;

[0026] The storage box 6 is provided with an enclosing downward-blowing hot-drying assembly electrically connected to the PLC controller 5, and side baffles 16 are rotatably installed on the top of both sides of the U-shaped plate 4, wherein a hinge is fixedly connected between the top of the side baffle 16 and the top of the U-shaped plate 4, and the side baffles 16 are rotatably installed with the U-shaped plate 4 through the hinge, which has the effect of rotatably installing the side baffles 16, and the bottom position of the side baffle 16 is higher than the top position of the cookie tray 100, which does not affect the normal transportation of the cookie tray 100. The enclosing downward-blowing hot-drying assembly is used to automatically perform hot-drying work from top to bottom after forming and discharging. The side baffles 16 and the U-shaped plate 4 are arranged to form a shielding effect on the hot air, reduce the phenomenon of large-scale outward loss of hot air, and improve the hot-drying effect. In addition, the rotatable installation method of the side baffles 16 makes it convenient for subsequent personnel to turn it away for internal inspection and maintenance or to add cookie materials.

[0027] Specifically, the conveying assembly includes two driving wheels 2 rotatably mounted between the front and rear inner walls of the U-shaped support 1, the two driving wheels 2 are connected to the same conveyor belt 201 for transmission, the front side of the U-shaped support 1 is fixedly mounted with a servo motor 202 whose output shaft is fixedly connected to the front side of the driving wheel 2 on the left side, the servo motor 202 is electrically connected to the PLC controller 5, a plurality of supporting rollers 3 are rotatably mounted between the front and rear inner walls of the U-shaped support 1, wherein the front end and rear side of the supporting roller 3 are fixedly connected with a pin shaft, a plurality of bearings are fixedly connected to the front and rear inner walls of the U-shaped support 1, the inner ring of the bearing is fixedly fitted with the outer side of the corresponding pin shaft, which plays the effect of rotatably mounting the supporting roller 3, and the top of the supporting roller 3 is connected to the conveying The inner top of the belt 201 is in rolling contact, and the multiple supporting rollers 3 provided play the role of supporting the conveyor belt 201 on the inner side to prevent it from collapsing. The cookie tray 100 is movably placed on the top of the conveyor belt 201; the driving wheel 2, conveyor belt 201, servo motor 202 and supporting roller 3 provided cooperate with each other, and the servo motor 202 is controlled by the PLC controller 5 to start and drive the driving wheel 2 on the left to rotate, and the driving wheel 2 on the left drives the conveyor belt 201 to rotate, and the rotating conveyor belt 201 is used to transport the cookie tray 100. When the PLC controller 5 receives the stop conveying signal, it controls the servo motor 202 to automatically shut down to stop the conveying work, and controls the next step of extrusion molding and discharge work.

[0028] Further, the automatic metering and extrusion assembly includes a multi-stage electric push rod 7 embedded and fixed on the top of the U-shaped plate 4. The extending end of the multi-stage electric push rod 7 extends into the U-shaped plate 4 and is fixedly connected to a pressing plate 8 adapted to the inner side of the storage bin 6. The top of the pressing plate 8 is fixedly connected to a reflecting sheet 9. Above the reflecting sheet 9, a laser distance sensor 10 fixedly connected to the inner wall of the top of the U-shaped plate 4 is arranged in a matching manner. Both the laser distance sensor 10 and the multi-stage electric push rod 7 are electrically connected to the PLC controller 5. The arranged multi-stage electric push rod 7, pressing plate 8, reflecting sheet 9 and laser distance sensor 10 cooperate. During use, first, the operator controls the multi-stage electric push rod 7 to drive the pressing plate 8 to move down until it contacts the cookie dough in the storage bin 6 and extrudes a part of the cookie dough, so that the cookie dough fills down into multiple forming nozzles 12. Then, the operator presets the stroke distance value for each time the multi-stage electric push rod 7 is controlled to close according to the amount of material to be extruded and discharged each time. When the PLC controller 5 receives the stop conveying signal, it also controls the multi-stage electric push rod 7 to start forward to drive the pressing plate 8 to press down on the cookie dough. Under the extrusion force, the cookie dough enters into multiple forming nozzles 12 for forming and is discharged downward into the cookie tray 100. When the pressing plate 8 moves down, it also drives the reflecting sheet 9 to move down. The laser distance sensor 10 detects the distance that the reflecting sheet 9 moves down each time and transmits the distance value of the downward movement to the PLC controller 5. When the preset value is reached, the PLC controller 5 controls the multi-stage electric push rod 7 to automatically close, achieving the effect of automatic quantitative forming and discharging each time.

[0029] Further, the surrounding downward blowing and heat drying assembly includes a return pipe 14 fixedly connected to the bottom of the storage bin 6. Multiple forming nozzles 12 are all located inside the return pipe 14. Both sides of the bottom of the return pipe 14 are fixedly connected and communicated with a plurality of air blowing covers 15. A hot air blower 13 electrically connected to the PLC controller 5 is fixedly installed on the right side of the storage bin 6. A connecting L-shaped pipe is fixedly connected between the air outlet of the hot air blower 13 and the right side of the return pipe 14. The arranged return pipe 14, air blowing covers 15, hot air blower 13 and L-shaped pipe cooperate. Using the PLC controller 5, it is preset to control the hot air blower 13 to start when the distance value of each downward movement reaches the preset value, and to control the servo motor 202 to start after the hot air blower 13 has been started for fifteen seconds. The hot air blower 13 is started after quantitative forming and discharging, and supplies hot air into the return pipe 14 through the L-shaped pipe. The hot air is blown into the cookie tray 100 from top to bottom through a plurality of air blowing covers 15 for heat drying work, reducing the natural drying time and improving work efficiency. After fifteen seconds of starting, the PLC controller 5 controls the servo motor 202 to start again to input the next cookie tray 100, and so on, realizing the automatic forming work of the cookie embryos. There is no need for personnel to stop the machine separately to replace the cookie tray 100. Only the personnel at the previous station need to place the cookie trays 100 one by one on the front side, further improving work efficiency.

[0030] The usage method of this embodiment is as follows: First, the operator squeezes the mixed cookie batter into the storage bin 6, and manipulates the multi-stage electric push rod 7 to drive the pressing plate 8 to move downward until it contacts and presses the cookie batter in the storage bin 6, so that the cookie batter fills down into multiple forming nozzles 12. The stroke distance value for each time the multi-stage electric push rod 7 is controlled to close is preset in advance by the PLC controller 5 according to the amount of material to be extruded and discharged each time, and when this distance value is reached, the hot air blower 13 is controlled to start for 15 seconds, and it is programmed to control the servo motor 202 to start after the hot air blower 13 has been on for 15 seconds; during forming, the servo motor 202 is started to drive the left driving wheel 2 to rotate. The left driving wheel 2 cooperates with the right driving wheel 2 to drive the conveyor belt 201 to rotate. The rotating conveyor belt 201 conveys the cookie tray 100 to the right. When the recognition camera 11 recognizes that the cookie tray 100 enters below the storage bin 6, it transmits a stop conveying signal to the PLC controller 5. At this time, the PLC controller 5 controls the servo motor 202 to pause, and at the same time controls the multi-stage electric push rod 7 to start forward to drive the pressing plate 8 to press downward on the cookie batter. Under the extrusion force, the cookie batter enters downward into multiple forming nozzles 12 for forming and is discharged downward into the cookie tray 100. When the pressing plate 8 moves downward, it also drives the reflection sheet 9 to move downward. The laser distance sensor 10 detects the distance of each downward movement of the reflection sheet 9 and transmits the distance value to the PLC controller 5. When the preset value is reached, the PLC controller 5 controls the multi-stage electric push rod 7 to automatically close, achieving the effect of automatic quantitative forming and discharging each time, facilitating the automatic control of the amount of extruded material each time and improving the forming accuracy;

[0031] When the preset extrusion stroke distance value is reached, the PLC controller 5 also controls the hot air blower 13 to start. The hot air blower 13 supplies hot air into the return pipe 14 through the L-shaped pipe. The hot air blows into the cookie tray 100 from top to bottom through multiple air blowing covers 15 for hot air drying work. At this time, the side baffle 16 and the U-shaped plate 4 cooperate to block the hot air, reducing the phenomenon of large-area outward loss of hot air and improving the hot air drying effect, making it convenient to automatically perform hot air drying to assist rapid drying work after shaping and discharging, reducing the time of natural drying and improving work efficiency. After the hot air blower 13 has been on for 15 seconds, the PLC controller 5 controls the hot air blower 13 to turn off and controls the servo motor 202 to start again. Similarly, the movement process is the same as when the servo motor 202 starts above, realizing the automatic output of the cookie tray 100 and the input of the next cookie tray 100 to continue the forming and drying work. By analogy, it realizes the automatic conveying of the cookie tray 100 after forming and continuous forming work without the operator having to stop the machine separately to replace the cookie tray 100. Only the operator at the previous station needs to place the cookie trays 100 one by one at the front side, improving work efficiency and the degree of automation in use.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
