Description
Technical Field
[0001] This utility model relates to the field of croissant processing technology, specifically a croissant forming machine. Background Technology
[0002] Croissants, also known as French croissants, are a type of bread with a crispy outer layer and a moist, soft interior. They are typically shaped like cow or sheep horns, hence the name. They are made by wrapping shortening in fermented dough, and then repeatedly pressing, rolling, and folding it to create a multi-layered bread. When cut open, they have a honeycomb-like structure with distinct layers. The process of making croissants involves rolling the triangular dough into a horn shape. The existing technology, authorized by publication number CN 115644199, details this process. B proposes a high-speed automated croissant forming machine and processing technology, including a frame, conveyor belt, dough making system, rolling and twisting device, and croissant forming device. The conveyor belt is set on the frame. The dough making system forms the raw material into an isosceles trapezoidal dough with a first arc part and a second arc part. The conveyor belt transports the isosceles trapezoidal dough to the rolling and twisting device station. The rolling and twisting device rolls the isosceles trapezoidal dough into a dough bar. The conveyor belt transports the dough bar to the croissant forming device station. The croissant forming device drives one end of the dough bar to bend to form a first curved croissant part, and the croissant forming device drives the other end of the dough bar to bend to form a second curved croissant part. Although the dough can be formed, after the dough is rolled, the dough is prone to loosening due to the rolling pressure, which affects the processing quality of the croissants. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This embodiment provides a technical solution: a croissant forming machine, including a frame 1, which provides support for the setting of the croissant dough forming component. A conveyor belt 2 is provided between the two horizontal plates of the frame 1 to transport the croissant dough. Rotatable forming rollers 3 are slidably connected in the grooves on the inner sides of the two vertical plates of the frame 1. The forming rollers 3 are all hollow rollers. The outer arc surface of the forming rollers 3 is provided with adsorption holes. The dough is adsorbed at the adsorption holes of the forming rollers 3 by using air pressure difference. As the forming rollers 3 rotate, the dough is rolled on the outer arc surface of the forming rollers 3 to form the dough. A single-chip microcomputer 14 is provided on the front surface of the frame 1. The input end of the single-chip microcomputer 14 is electrically connected to an external power source to control the start and stop of the whole device. The conveyor belt 2 is an electric conveyor belt. The input end of the conveyor belt 2 is electrically connected to the output end of the single-chip microcomputer 14. It also includes a kneading mechanism 4.
[0021] The pressing mechanism 4 includes a sliding frame 41, a pressure plate 42, sliding columns 43, and springs 44. The sliding frame 41 is vertically slidably connected between two vertical plates of the frame 1. Sliding columns 43 are vertically slidably connected in the sliding holes on the top wall of the sliding frame 41. A pressure plate 42 is provided between the lower ends of the three sliding columns 43, located above the two forming rollers 3. Springs 44 are provided between the sliding plate at the upper end of the sliding column 43 and the frame 1. The springs 44 are movably sleeved on the outer arc surface of the sliding column 43. During the forming process, as the dough rolls more on the outer arc surface of the forming roller 3, when the dough comes into contact with the pressure plate 42, as the dough continues to roll, the dough will exert a force on the pressure plate 42, overcoming the elastic force of the springs 44, and pushing the sliding columns 43 to slide within the sliding holes of the sliding frame 41. The elastic force of the pressure plate 42 applies downward pressure to the blank. As the forming roller 3 continues to move upward, the forming roller 3 no longer drives the blank to wind. The pressure plate 42 always applies a downward and constant force to the blank, pressing the blank onto the surface of the conveyor belt 2. As the conveyor belt 2 rotates, the blank is pressed and shaped into a cow horn shape. The pressing mechanism 4 also includes a sliding plate 45, a rotating tube 46, and a turntable 47. The sliding plate 45 is vertically slidably connected to the inside of the vertical plate of the frame 1. The rotating tube 46 is rotatably connected to the rotating groove inside the sliding plate 45. The outer arc surface of the rotating tube 46 is provided with a turntable 47. The opposite inner surfaces of the two turntables 47 are provided with planar spiral grooves. The cylinders at the front and rear ends of the sliding frame 41 are slidably connected to the inside of the adjacent planar spiral grooves. Tubes 46 are movably sleeved on the outer arc surface of the forming roller 3. During the pressing and kneading process, the turntable 47 rotates together with the rotating tubes 46, causing the cylinders at both ends of the sliding frame 41 to slide in the spiral grooves on the surface of the turntable 47. This gradually increases the distance between the pressure plate 42 and the forming roller 3, providing space for the winding of the dough blank and preventing the pressure plate 42 from applying excessive force to the dough blank, thus ensuring the pressing and kneading quality. The kneading mechanism 4 also includes an outer toothed ring 48 and a toothed plate 49. The outer toothed rings 48 are respectively located on the side of the rotating tube 46 away from the conveyor belt 2. The hexagonal columns of the forming roller 3 are longitudinally slidably connected to the hexagonal grooves of the adjacent outer toothed rings 48. The toothed plates 49 are respectively located inside the vertical plate of the frame 1, and the toothed plates 49 are meshed with the adjacent outer toothed rings 48. When the sliding plate 45 drives the rotating tube 46 upward... During movement, the external gear ring 48 rotates through the meshing connection with the rack plate 49. Because the hexagonal prism of the forming roller 3 slides longitudinally with the hexagonal groove of the external gear ring 48, the relative rotation between the forming roller 3 and the external gear ring 48 is restricted, so the forming roller 3 also rotates. The inner wall of the vertical plate of the frame 1 is provided with a limiting plate 5. The outer arc surface of the forming roller 3 away from the conveyor belt 2 is rotatably connected to a top pressure plate 6. The upper end of the top pressure plate 6 is provided with a rotary joint. The rotating end of the rotary joint is fixedly connected to and communicates with the forming roller 3. The outer arc surface of the fixed end of the rotary joint is fixedly connected to the top pressure plate 6. The top pressure plate 6 is vertically slidably connected to the inside of the vertical plate of the frame 1. The semi-circular protrusion at the lower end of the top pressure plate 6 is installed in conjunction with the limiting plate 5. The outer arc surface of the forming roller 3 is movably sleeved with a top pressure spring 7.One end of the top pressure spring 7 near the conveyor belt 2 is fixedly connected to the adjacent fixed external toothed ring 48, and the other end of the top pressure spring 7 is in contact with the adjacent top pressure plate 6. When the forming roller 3 starts to move upward, under the elastic force of the top pressure spring 7, the semi-circular protrusion of the top pressure plate 6 contacts the vertical plate of the limiting plate 5, keeping the forming roller 3 moving vertically upward. After the pressure plate 42 applies pressure to the blank, as the forming roller 3 continues to move upward, the semi-circular protrusion of the top pressure plate 6 contacts the inclined plate of the limiting plate 5, driving the forming roller 3 to gradually move upward. The dough is extracted from the coiled dough. Inside the vertical plate of the frame 1, there is a vacuum pump 8 and a solenoid valve 9. The air inlet of the vacuum pump 8 is connected to the interior of the adjacent forming roller 3 via a flexible hose. The flexible hose is connected to the fixed end of the rotary joint at the upper end of the top pressure plate 6. The solenoid valve 9 is connected in series in the middle of the flexible hose. The input ends of both the vacuum pump 8 and the solenoid valve 9 are electrically connected to the output end of the microcontroller 14. When the dough contacts the outer arc surface of the forming roller 3, the vacuum pump 8 is activated, causing air to circulate inside the hollow forming roller 3. Under negative pressure and atmospheric pressure, the blank is adsorbed onto the adsorption holes on the outer arc surface of the forming roller 3. When the pressure plate 42 applies pressure to the blank, the solenoid valve 9 opens, restoring the internal air pressure of the forming roller 3 to normal pressure and canceling the adsorption of the blank. Screws 10 are rotatably connected between the upper and lower inner walls of the vertical plate of the frame 1. The screws 10 are threadedly connected to the screw holes on the surface of the sliding plate 45. Worm gears 11 are provided at the lower ends of the screws 10. Worms 12 are rotatably connected between the front and rear inner walls of the frame 1. The worm gears 11 are all connected to the worms. A 12-meshing connection is established. A motor 13 is mounted on the front surface of the frame 1. The output shaft of the motor 13 is fixedly connected to the front end of the worm gear 12. The input end of the motor 13 is electrically connected to the output end of the microcontroller 14. When the motor 13 is started, its output shaft drives the worm gear 12 to rotate. Through the meshing connection between the worm gear 12 and the worm wheels 11, the two worm wheels 11 drive the screw 10 to rotate. Through the meshing connection between the screw 10 and the sliding plate 45, the sliding plate 45 moves up and down under the constraint of the inner wall of the vertical plate of the frame 1.
[0022] The working principle of the croissant forming machine provided by this utility model is as follows: During the croissant processing, the slit triangular dough blanks are placed on the upper surface of the conveyor belt 2. The conveyor belt 2 is started by the microcontroller 14, and the triangular dough blanks are conveyed to the right by the conveyor belt 2. According to the conveying speed of the dough blanks, when the dough blanks come into contact with the outer arc surface of the forming roller 3, the vacuum pump 8 is started to create a negative pressure inside the hollow forming roller 3. Under the action of atmospheric pressure, the dough blanks are adsorbed at the adsorption holes on the outer arc surface of the forming roller 3. Then, the motor 13 is started, and the output shaft of the motor 13 drives the worm gear 12 to rotate. Through the meshing connection between the worm gear 12 and the worm wheel 11, the two worm wheels 11 drive... The screw 10 rotates, and through the meshing connection between the screw 10 and the sliding plate 45, under the limitation of the inner wall of the vertical plate of the frame 1, the sliding plate 45 drives the rotating tube 46 to move upward, driving the forming roller 3 to move upward. At this time, under the elastic force of the top pressure spring 7, the semi-circular protrusion of the top pressure plate 6 contacts the vertical plate of the limiting plate 5, keeping the forming roller 3 moving vertically upward, providing space for the blank to be wound on the outer arc surface of the forming roller 3. During the movement, through the meshing connection between the outer toothed ring 48 and the toothed plate 49, the outer toothed ring 48 rotates. Because the hexagonal prism of the forming roller 3 and the hexagonal groove of the outer toothed ring 48 slide longitudinally, the relative rotation of the forming roller 3 and the outer toothed ring 48 is restricted, so the forming roller 3 is formed. Roller 3 also rotates, rolling up the end of the dough blank. As more of the dough blank is wound around the outer arc surface of forming roller 3, when the dough blank comes into contact with pressure plate 42, as the dough blank continues to wind, the dough blank will exert a force on pressure plate 42, overcoming the elastic force of spring 44, and pushing slide column 43 to slide in the sliding hole of sliding frame 41. Under the elastic force of spring 44, pressure plate 42 applies downward pressure to the dough blank. At this time, as forming roller 3 continues to move upward, the semi-circular protrusion of top pressure plate 6 contacts the inclined plate of limit plate 5. At the same time, solenoid valve 9 opens, so that the air pressure inside forming roller 3 returns to normal pressure, canceling the adsorption of dough blank. As forming roller 3 moves upward, forming roller 3 gradually moves away from the wound dough blank. During the extraction process, the pressure plate 42 always applies a downward force to the blank, pressing the blank onto the surface of the conveyor belt 2. As the conveyor belt 2 rotates, the blank is pressed and shaped into a cow horn shape. During the pressing and rubbing process, the turntable 47 rotates together with the rotating tube 46, causing the cylinders at both ends of the sliding frame 41 to slide in the spiral groove on the surface of the turntable 47. This gradually increases the distance between the pressure plate 42 and the forming roller 3, providing space for the winding of the blank and preventing the pressure plate 42 from applying too much force to the blank, thus ensuring the pressing and rubbing quality. After the forming is completed, the cow horn blank continues to be conveyed to the right with the conveyor belt 2, and the output shaft of the motor 13 reverses, driving the forming roller 3 and the pressure plate 42 to reset.
[0023] It is worth noting that the microcontroller 14 disclosed in the above embodiments can be a PI C16F1823-I / P model microcontroller. The conveyor belt 2, the vacuum pump 8, the solenoid valve 9 and the motor 13 can be freely configured according to the actual application scenario. The conveyor belt 2 can be an RF-PDSSJ model electric conveyor belt, the vacuum pump 8 can be a TNY21-4D model suction pump, the solenoid valve 9 can be a YCA21-25 model solenoid valve, and the motor 13 can be an LS60A30 model stepper motor. The microcontroller 14 controls the operation of the conveyor belt 2, the vacuum pump 8, the solenoid valve 9 and the motor 13 using methods commonly used in the prior art.
