[0005] In view of this, this utility model is proposed. Utility Model Content
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A dough thickness adjustment structure for a dessert bun forming machine, including An operating console, wherein a conveyor belt is installed inside the operating console; A lever adjustment mechanism is movably mounted on the operating table. The lever adjustment mechanism includes a worm gear, a worm wheel, a mounting frame, a pressing roller, and a sliding box. The worm wheel is fixedly mounted on one side of the mounting frame. The worm gear is rotatably mounted on the outside of the operating table. The mounting frame is rotatably mounted inside the operating table. Multiple pressing rollers are arranged in an array inside the mounting frame. The sliding box is slidably mounted between the mounting frame and the operating table.
[0007] In a preferred embodiment of this utility model, a transmission motor and an electrical control box are fixedly installed on one side of the operating table. The worm gear and worm wheel are rotatably installed inside the electrical control box. The output end of the transmission motor is connected to the drive shaft at one end of the conveyor belt through a coupling.
[0008] In a preferred embodiment of this utility model, a motor base is fixedly installed inside the electrical control box. A worm gear is rotatably connected to one side of the motor base, and a drive motor is fixedly installed on the other side of the motor base. The output end of the drive motor is connected to one end of the worm gear through a coupling inside the motor base, and the worm gear meshes with a worm wheel.
[0009] In a preferred embodiment of this utility model, a T-shaped groove is provided on the other side of the operating table, a scale is installed on the outer side of the operating table, and a display block is fixed on the side of the sliding box away from the mounting frame. The sliding box and the display block form a T-shaped structure corresponding to the shape of the T-shaped groove, and the sliding box and the display block slide together in the same T-shaped groove.
[0010] In a preferred embodiment of this utility model, the mounting frame is fixed to the worm gear by a shaft at one end, and a slider is rotatably provided at one end corner of the mounting frame. The slider slides in the sliding box. A slot is provided inside the mounting frame, and a top plate is fixed to the slot by bolts.
[0011] In a preferred embodiment of the present invention, a plurality of T-shaped support plates are arrayed inside the mounting frame, and a pressing roller is rotatably arranged between every two T-shaped support plates.

Simultaneously, with the cooperation of the sliding box and the slider, the display block flush with the bottom surface of the pressing rollers and the scale display are made. At this time, the swinging motion of the mounting frame adjusts the thickness between the pressing roller at one end and the conveyor belt, so that all the pressing rollers in the mounting frame and the conveyor belt form a pressing end that gradually narrows from wide to narrow. This gradually equalizes the thickness and shape of the pressed dough, avoiding uneven sizes and thicknesses in the dough.
[0014] 2. During the rotation of the dough pressing roller, the silicone brushes and scrapers located on both sides of the dough pressing roller are always in contact with the surface of the dough pressing roller.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0019] A dough thickness adjustment structure for a dessert bun forming machine, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including The control table 10 is equipped with a conveyor belt 12 for conveying dough sheets. A lever adjustment mechanism is movably mounted on the operating table 10 and located above the conveyor belt 12. The lever adjustment mechanism includes a worm gear 17, a worm wheel 18, a mounting frame 20, pressing rollers 23, and a sliding box 25. The worm wheel 18 is fixedly mounted on one side of the mounting frame 20, the worm gear 17 is rotatably mounted on the outside of the operating table 10, the mounting frame 20 is rotatably mounted inside the operating table 10, and multiple pressing rollers 23 are arrayed inside the mounting frame 20. The sliding box 25 is slidably mounted between the mounting frame 20 and the operating table 10. The surface of the pressing rollers 23 is polished to prevent the dough from sticking. like Figure 1 As shown, a conveyor motor 13 and an electrical control box 14 are fixedly installed on one side of the operating table 10. The worm gear 17 and worm wheel 18 are rotatably installed inside the electrical control box 14. The electrical control box 14 is a sealed structure. A door is hinged on the side of the electrical control box 14 away from the operating table 10 to seal the interior. A control panel is installed on the outside of the door. The control panel is electrically connected to the conveyor motor 13 and the drive motor 15. The output end of the conveyor motor 13 is connected to the drive shaft of one end of the conveyor belt 12 through a coupling. The conveyor motor 13 is fixed to the left side wall of the operating table 10 by bolts. Its output shaft is connected to the drive shaft of the drive roller of the conveyor belt 12 through a coupling to realize the continuous conveying of dough sheets. like Figure 1 As shown, a motor base 16 is fixedly installed inside the electrical control box 14. A worm gear 17 is rotatably connected to one side of the motor base 16, and a drive motor 15 is fixedly installed on the other side of the motor base 16. The output end of the drive motor 15 is connected to one end of the worm gear 17 through a coupling inside the motor base 16. The worm gear 17 drives and meshes with the worm wheel 18. like Figure 1 and Figure 2 As shown, a T-shaped groove 19 is provided on the other side of the operating table 10. A scale 22 for displaying the thickness of the dough is installed on the outer side of the operating table 10. The scale 22 is flush with the vertical line of the T-shaped groove 19. A display block 26 is fixed on the side of the sliding box 25 away from the mounting frame 20. The sliding box 25 and the display block 26 form a T-shaped structure corresponding to the shape of the T-shaped groove 19. The sliding box 25 and the display block 26 slide up and down in the same T-shaped groove 19. The bottom surface of the limiting block 26 is flush with the bottom curved surface of the pressing roller 23. The display block 26 slides vertically in the T-shaped groove 19. The bottom surface of the limiting block 26 is used axially to cooperate with the scale 22 to display the scale of the pressing roller 23 at the current adjacent position, thereby indicating the current thickness of the dough. like Figure 3 , Figure 4 and Figure 5As shown, a shaft column is provided on each side of the mounting frame 20. The mounting frame 20 is rotatably mounted in the operating table 10 through the shaft columns on both sides. The mounting frame 20 is fixed to the worm gear 18 through one end of the shaft column. A slider 24 is rotatably mounted on one end of the mounting frame 20. A cylinder is fixedly mounted on one end of the mounting frame 20 near 19. The mounting frame 20 is rotatably connected to the slider 24 through the cylinder. The slider 24 slides in the sliding box 25. A slot 28 is opened inside the mounting frame 20. A top plate 21 is fixed to the slot 28 by bolts.
[0020] Specifically, when the dough thickness needs to be adjusted, the operator starts the drive motor 15 through the control panel of the electrical control box 14. The drive motor 15 drives the worm gear 17 to rotate. Since the worm gear 17 meshes with the worm wheel 18, the worm wheel 18 rotates accordingly, causing the mounting frame 20 to swing upward around one side of the shaft. At this time, the slider 24 of the mounting frame 20 is horizontally displaced relative to the sliding box 25 due to the swing of the mounting frame 20, pushing the sliding box 25 up and down along the T-shaped slide groove 19. At the same time, the pressing roller 23 inside the mounting frame 20 changes its vertical distance from the conveyor belt 12, i.e., the dough thickness, due to the tilt of the mounting frame 20. The higher the mounting frame 20 is raised, the more the pressing roller 23 at one end moves up and down. The smaller the distance between 3 and the conveyor belt 12, the thinner the dough is pressed; conversely, the larger the distance, the thicker it is. During the adjustment process, the display block 26 rises and falls synchronously with the sliding box 25. The position of its bottom axial direction compared with the scale 22 is the current dough thickness. The lever adjustment characteristic of this structure is that the mounting frame 20 is the lever, the shaft column is the fulcrum, the driving force of the worm gear 18 is the input force, and the contact force between the pressing roller 23 and the dough is the output force. With the self-locking function of the worm gear 18 and the worm 17, all the pressing rollers 23 in the mounting frame 20 and the conveyor belt 12 form pressing ends that go from wide to narrow, so that the thickness and shape of the pressed dough are gradually balanced, avoiding the situation where the dough is of different sizes and thicknesses.
[0021] like Figure 3 and Figure 4 As shown, multiple T-shaped support plates 27 are arrayed inside the mounting frame 20, and a pressing roller 23 is rotatably arranged between every two T-shaped support plates 27; as Figure 4 and Figure 5 As shown, silicone brushes 29 and scrapers 30 are fixed to both sides of the T-shaped support plate 27 by bolts. The silicone brushes 29 and scrapers 30 are located on both sides of the pressing roller 23. The silicone brushes 29 and scrapers 30 are fixed between the top plate 21 and the T-shaped support plate 27. The bottom surface of the top plate 21 has multiple semi-circular grooves with a diameter greater than or equal to that of the pressing roller 23. The bottom of the top plate 21 contacts the top of the silicone brushes 29 and scrapers 30, which can be used to limit the rotation of the pressing roller 23 and to hold the silicone brushes 29 and scrapers 30 in place, so as to prevent the silicone brushes 29 and scrapers 30 from shifting due to loosening of the bolts during long-term use.
[0022] Specifically, during the dough pressing process, a small amount of dough scraps will inevitably stick to the surface of the dough pressing roller 23. As the mounting frame 20 swings during the adjustment process, the silicone brush 29 and the scraper 30 will continuously contact and rub against the surface of the dough pressing roller 23. The silicone brush 29 removes loose dough scraps through flexible contact, while the scraper 30 removes stubborn sticky substances through rigid contact. The two work together to ensure that the surface of the dough pressing roller 23 is always clean. This real-time cleaning method avoids the long-term accumulation of dough residue and the growth of bacteria, effectively ensuring the safety of food processing.
