Description

Technical Field

[0001] This invention relates to the field of steamed bun skin processing, specifically to an automatic steamed bun skin forming and thickness control device. Background Technology

[0002] The process of making steamed buns and other foods involves first kneading flour into a dough, then rolling the dough into a thin sheet, and then using a mold to press the dough into a bun wrapper. The bun wrappers are then collected. When processing steamed buns in large quantities, a bun wrapper machine is usually used to press the dough into bun wrappers of a specified shape.

[0003] Patent document CN117814436A discloses a process for preparing steamed bun skins; including the following steps: S1: Weighing and mixing flour, water, baking soda, and baking powder in proportion; S2: Proofing the mixed dough; Dividing the proofed dough and placing it on a feeding roller; S3: The dough is fed to the rolling roller and forming roller of the steamed bun skin machine, where it is pressed and cut into thin and soft steamed bun skins. This steamed bun skin preparation process uses a sponge roller to coat the flour in the hopper onto the forming blade. On the one hand, when the forming blade cuts the skin, the flour absorbs the moisture on the skin, preventing the dough from sticking to the forming blade and ensuring a smooth surface, thus improving the forming effect of the steamed bun skin. On the other hand, it prevents the dough from sticking to the forming blade and breeding bacteria, thus preventing the dough from contaminating the steamed bun skin it comes into contact with and improving the food safety of the steamed bun skin. However, the following shortcomings still exist.

[0004] The process for preparing steamed bun wrappers in the aforementioned patent document involves setting up a forming roller to form the dough into wrappers. However, the structure of the forming roller is relatively simple, making it impossible to adjust the thickness of the wrappers when processing them. Therefore, an automatic forming and thickness control device for steamed bun wrappers is proposed to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, an automatic bun wrapper forming and thickness control device is provided. By setting two sets of adjustable mechanisms on both sides of the turbine, and having the two sets of adjustable mechanisms move in opposite directions simultaneously, the active worm gear rotates and drives the adjustable mechanisms to extend or retract simultaneously through the turbine. This enables the forming roller to produce bun wrappers from dough of different thicknesses, thus solving the problem of poor applicability of the forming roller.

[0006] To address the problems of existing technologies, this invention provides an automatic bun skin forming and thickness control device, comprising a base plate, two support plates on the upper surface of the base plate, a material feeding platform for placing materials on the inner side of the top of the support plates, and a material conveying device for conveying materials horizontally arranged at the center of the upper surface of the base plate.

[0009] As one technical solution of the present invention, a bidirectional telescopic assembly is horizontally installed on the feeding platform, and a baffle plate that can move horizontally is fixed on the bidirectional telescopic assembly.

[0010] As a technical solution of the present invention, the support plate is symmetrically provided with sliding grooves, and an electric telescopic component is provided on the outer side of the support plate near the top of the sliding groove. The output end of the electric telescopic component is fixed with a limiting sliding seat that can slide along the inside of the sliding groove. The outer surface of the limiting sliding seat is fixed with a first rotary drive component, and a movable rolling roller is provided between the two support plates. The two ends of the movable rolling roller are respectively rotatably disposed on the limiting sliding seat, and one end of the movable rolling roller is fixedly connected to the output end of the first rotary drive component.

[0011] As one technical solution of the present invention, a second rotary drive member is provided on the outer side of the support plate, and an active rolling roller is provided at the output end of the second rotary drive member.

[0012] As one technical solution of the present invention, a driven rolling roller is provided between the two support plates. The two ends of the driven rolling roller are rotatably mounted on the support plates, and one end of the driven rolling roller can extend to the outside of the support plate.

[0013] As one technical solution of the present invention, a first limiting roller is provided between the two support plates, and one end of the first limiting roller is rotatably mounted on the support plate.

[0014] As a technical solution of the present invention, a first gear for transmission is provided on the outer side of the support plate. The first gear is installed at the end of the active rolling roller away from the second rotating drive member. A second gear is movably provided on the outer side of the support plate near the first gear. The first gear meshes with the second gear. The second gear is installed at the extension end of the driven rolling roller. A belt groove is provided on one side of the second gear. A second transmission belt is fitted on the belt groove. A first pulley that can be movably connected to the second transmission belt is also provided on the outer side of the support plate.

[0015] As one technical solution of the present invention, a second pulley is fixed to the outside of one end of the mounting shaft, and the second pulley can be movably connected to the first transmission belt.

[0016] As a technical solution of the present invention, the bracket is provided with a second limiting roller that enables the material to move horizontally, and the second limiting roller is located at the top of the material conveying device, and a first guide roller is also provided on the bracket near the top of the second limiting roller.

[0017] As a technical solution of the present invention, the bracket is further provided with a second guide roller, and the second guide roller can be connected to the waste material conveying device through a hinge.

[0018] As one technical solution of the present invention, a guide roller shaft is provided between the two support plates near the feeding platform, and the guide roller shaft is installed on the top of the two sets of support plates.

[0019] The advantages of this invention compared to the prior art are:

[0020] 1. This application fixes the built-in fixing frame inside the forming roller, causing the forming roller to drive the built-in fixing frame to rotate axially in the horizontal direction. The active worm gear is horizontally installed inside the built-in fixing frame, and a knob is set at the extension end of the active worm gear so that the knob can drive the active worm gear to rotate. Then, a turbine that can mesh with the active worm gear is set on the built-in fixing frame, and two sets of adjustment mechanisms that can move in opposite directions are set on both sides of the turbine gear. When the active worm gear rotates, it drives the adjustment mechanism to extend or retract simultaneously through the turbine gear. This enables the forming roller to make bun wrappers from dough of different thicknesses, solving the problem of poor applicability of the forming roller.

[0021] 2. This application achieves automatic material discharge by having the driven worm gear move longitudinally while the sleeve, return spring, and movable rod drive the pusher block to move along the inside of the forming mold. This allows the pusher block to be adjusted to its pre-set position inside the forming mold, enabling the forming mold to adapt to the processing requirements of dough sheets of different thicknesses. Furthermore, during the process of the forming mold turning the dough sheet into a bun wrapper, when the pusher block is subjected to reverse pressure from the dough sheet, the pusher block drives the movable rod to press against the return spring, causing the pusher block to shrink. After the forming mold turns the dough sheet into a bun wrapper, the return spring pushes the pusher block back to its original position via the movable rod, simultaneously pushing the bun wrapper out of the forming mold. This solves the problem of bun wrappers easily sticking to the inside of the forming mold. Attached Figure Description

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] See Figures 1-11 As shown, an automatic bun skin forming and thickness control device includes a base plate 1. Two support plates 11 are arranged on the upper surface of the base plate 1. A material feeding platform 3 for placing materials is arranged on the inner side of the top of the support plates 11. A material conveying device 2 for conveying materials is horizontally arranged at the center of the upper surface of the base plate 1. A rotatable forming roller 7 is arranged between the two support plates 11. The forming roller 7 has several mounting holes 71, and a forming mold 72 is installed inside the mounting holes 71. The forming roller 7 also has an internal fixing mechanism. The frame 76 has a horizontally mounted rotatable drive worm gear 77, with a knob 771 at one end. The frame 76 also has a turbine 78 that meshes with the drive worm gear 77. Two sets of longitudinally adjustable adjustment mechanisms 79 are mounted on both sides of the turbine 78, and the two sets of adjustment mechanisms 79 are mounted in opposite directions on the frame 76. The upper surface of the base plate 1 is also provided with a bracket 8, and a waste material conveying device 9 for discharging waste material is horizontally mounted on the top of the bracket 8.

[0037] In use, the built-in fixing frame 76 is fixed inside the forming roller 7, causing the forming roller 7 to drive the built-in fixing frame 76 to rotate axially in the horizontal direction. The active worm gear 77 is horizontally installed inside the built-in fixing frame 76, and a knob 771 is set at the extension end of the active worm gear 77, so that the knob 771 can drive the active worm gear 77 to rotate. Then, a turbine 78 that can mesh with the active worm gear 77 is set on the built-in fixing frame 76, and two sets of adjusting mechanisms 79 that can move in opposite directions are set on both sides of the turbine 78, so that when the active worm gear 77 rotates, the turbine 78 drives the adjusting mechanism 79 to extend or retract simultaneously, so that the forming roller 7 can make bun wrappers of different thicknesses of dough.

[0038] See Figure 6 , Figure 7 , Figure 8 and Figure 12 As shown, the adjustment mechanism 79 includes a driven worm gear 791 mounted on the built-in fixed frame 76 and meshing with the worm gear 78. A sleeve 792 is movably disposed at the top end of the driven worm gear 791. A return spring 793 is disposed inside the sleeve 792. A movable rod 794 capable of longitudinal movement is also disposed inside the sleeve 792. The top end of the return spring 793 abuts against the bottom end of the movable rod 794. A limiting plate 796 for limiting the movable rod 794 is disposed at the top end of the sleeve 792. A pusher block 795 is fixed at the top end of the limiting plate 796. The pusher block 795 is inserted into the interior of the molding die 72 and can move along the interior of the molding die 72.

[0039] In use, the driven worm gear 791 moves longitudinally while the sleeve 792, return spring 793, and movable rod 794 drive the pusher block 795 to move along the inside of the forming mold 72. This adjusts the reserved position of the pusher block 795 inside the forming mold 72, allowing the forming mold 72 to adapt to the processing requirements of dough of different thicknesses. When the forming mold 72 is making the dough into a bun wrapper, the pusher block 795 is subjected to reverse pressure from the dough. The pusher block 795 drives the movable rod 794 to press the return spring 793, causing the pusher block 795 to contract. After the forming mold 72 has made the dough into a bun wrapper, the return spring 793 pushes the pusher block 795 back to its original position through the movable rod 794, and pushes the bun wrapper out of the inside of the forming mold 72 for automatic material discharge, avoiding the problem of the bun wrapper easily sticking to the inside of the forming mold 72.

[0040] See Figure 1 and Figure 5 As shown, end caps 73 are fixed at both ends of the forming roller 7, and an installation shaft 74 is provided at the center of the outer side of the end cap 73, and the installation shaft 74 can penetrate the support plate 11.

[0041] In use, two sets of end caps 73 are symmetrically arranged at both ends of the forming roller 7, so that the end caps 73 fix the built-in fixing frame 76 inside the forming roller 7.

[0042] See Figure 9 As shown, a bidirectional telescopic assembly 31 is horizontally installed on the feeding platform 3, and a baffle plate 32 that can move horizontally is fixed on the bidirectional telescopic assembly 31.

[0043] In use, the bidirectional telescopic component 31 is horizontally fixed on the feeding platform 3, and two sets of baffles 32 are set on the bidirectional telescopic component 31, so that the bidirectional telescopic component 31 drives the two sets of baffles 32 to move synchronously. By adjusting the distance between the two sets of baffles 32, the baffles 32 limit the surface blank.

[0044] See Figure 1 , Figure 2 and Figure 10 As shown, symmetrical grooves 12 are arranged on the support plate 11. An electric telescopic component 13 is arranged on the outer side of the support plate 11 near the top of the groove 12. A limiting sliding seat 14 that can slide along the inside of the groove 12 is fixed to the output end of the electric telescopic component 13. A first rotary drive component 15 is fixed on the limiting sliding seat 14. A movable rolling roller 16 is arranged between the two support plates 11. Both ends of the movable rolling roller 16 are rotatably arranged on the limiting sliding seat 14. One end of the movable rolling roller 16 is fixedly connected to the output end of the first rotary drive component 15.

[0045] In use, the electric telescopic component 13 is fixed to the outside of the support plate 11 near the top of the electric telescopic component 13, and a limiting sliding seat 14 is provided at the output end of the electric telescopic component 13, so that the electric telescopic component 13 drives the limiting sliding seat 14 to slide along the inner side of the slide groove 12, and a movable rolling roller 16 is rotated at the center of the limiting sliding seat 14, so that the limiting sliding seat 14 drives the movable rolling roller 16 to approach the driven rolling roller 6, thereby adjusting the thickness of the dough blank. One end of the movable rolling roller 16 is installed at the output end of the first rotary drive component 15, so that the first rotary drive component 15 drives the movable rolling roller 16 to rotate.

[0046] See Figure 1 , Figure 2 and Figure 10 As shown, a second rotary drive member 52 is provided on the outer wall of the support plate 11, and an active rolling roller 5 is provided at the output end of the second rotary drive member 52.

[0047] In use, the second rotary drive 52 is fixed to the outside of the support plate 11, and an active rolling roller 5 is provided at one end of the second rotary drive 52, so that the second rotary drive 52 drives the active rolling roller 5 to rotate.

[0048] SeeFigure 10 As shown, a driven rolling roller 6 is provided between the two sets of support plates 11 near the bottom of the active rolling roller 5. The two ends of the driven rolling roller 6 are rotatably mounted on the support plate 11, and one end of the driven rolling roller 6 can extend to the outside of the support plate 11.

[0049] In use, the driven rolling roller 6 is rotatably mounted on the inner side of the support plate 11 near the bottom of the active rolling roller 5, and a second gear 61 that can mesh with the first gear 51 is provided at the extended end of the driven rolling roller 6. This allows the active rolling roller 5 to rotate while the first gear 51 drives the second gear 61, which in turn drives the driven rolling roller 6 to rotate. This allows the driven rolling roller 6 to rotate synchronously with the active rolling roller 5, thereby enabling the active rolling roller 5 and the driven rolling roller 6 to cooperate in the initial rolling of the dough, making the thickness of the dough closer to the processing requirements.

[0050] See Figure 1 As shown, a first limiting roller 17 is provided between the two sets of support plates 11, and the two ends of the first limiting roller 17 are rotatably mounted on the support plate 11.

[0051] In use, by rotating the first limiting roller 17 to be installed inside the support plate 11, and with the first limiting roller 17 positioned on the upper end of the dough blank, the dough blank can be laid flat on the upper surface of the material conveying device 2.

[0052] See Figure 1 , Figure 2 and Figure 10 As shown, a first gear 51 for transmission is provided on the outer side of the support plate 11. The first gear 51 is installed at the end of the active rolling roller 5 away from the second rotary drive member 52. A second gear 61 is movably provided on the outer side of the support plate 11 near the first gear 51. The first gear 51 meshes with the second gear 61. The second gear 61 is installed at the extension end of the driven rolling roller 6. A belt groove 62 is provided on one side of the second gear 61. A second transmission belt 63 is fitted on the belt groove 62. A first pulley 171 that can be movably connected to the second transmission belt 63 is also provided on the outer side of the support plate 11. The first pulley 171 is fixed to one end of the first limiting roller 17.

[0053] In use, by fixing the first gear 51 to one end of the active rolling roller 5 and enabling the first gear 51 to mesh with the second gear 61, and fixing the second gear 61 to the extension end of the driven rolling roller 6, the active rolling roller 5 rotates while the second gear 61 drives the driven rolling roller 6 to rotate. By providing a belt groove 62 on one side of the second gear 61 and movably connecting the belt groove 62 to the first pulley 171 via the second transmission belt 63, the second gear 61 rotates while the first pulley 171 rotates via the second transmission belt 63, and the first pulley 171 drives the first limiting roller 17 to rotate. Thus, the active rolling roller 5, the driven rolling roller 6, and the first limiting roller 17 can work simultaneously.

[0054] See Figure 1 As shown, a second pulley 75 is fixed to the outside of one end of the mounting shaft 74, and a first transmission belt 172 that can be movably connected to the first pulley 171 is movably disposed on the second pulley 75.

[0055] In use, a second pulley 75 is provided at one end of the mounting shaft 74, and the first transmission belt 172 is movably mounted on the second pulley 75 and 171 respectively, so that the first pulley 171 drives the second pulley 75 to rotate through the first transmission belt 172, thereby causing the second pulley 75 to drive the mounting shaft 74 to rotate.

[0056] See Figure 1 As shown, a second limiting roller 81 capable of moving the material horizontally is provided on the bracket 8, and the second limiting roller 81 is located at the top of the material conveying device 2. A first guide roller 82 is also provided on the bracket 8 near the top of the second limiting roller 81.

[0057] In use, the second limiting roller 81 is movably mounted on the bracket 8, and the second limiting roller 81 is located on the upper end face of the dough scrap, so as to prevent the scrap from separating from the upper end face of the material conveying device 2 when it moves upward.

[0058] See Figure 1 As shown, a second guide roller 83 is also provided on the bracket 8, and the second guide roller 83 can be connected to the waste material conveying device 9 via a hinge.

[0059] In use, the second guide roller 83 is movably mounted on the top of the bracket 8, and the second guide roller 83 can be connected to the waste material conveying device 9 through a hinge. When the waste material conveying device 9 is running, the second guide roller 83 is driven to rotate through the hinge, so that the second guide roller 83 and the waste material conveying device 9 cooperate to output the waste dough, thus avoiding the waste dough falling back during the conveying process.

[0060] See Figure 1 and Figure 2As shown, there is a guide roller shaft 4 between the two sets of support plates 11 near the feeding platform 3, and the guide roller shaft 4 is installed on the top of the two sets of support plates 11.

[0061] In use, by rotating the guide roller shaft 4 to the top of the support plate 11, the dough blanks are allowed to pass around the outer surface of the guide roller shaft 4, thus preventing the dough blanks from rubbing against the feeding table 3 when being fed.

[0062] This application places the dough blank on the upper surface of the feeding platform 3, and uses the bidirectional telescopic component 31 to drive the baffle plate 32 to limit the two sides of the dough blank. Then, the dough blank is wound around the outer surface of the guide roller shaft 4 and between the active rolling roller 5 and the driven rolling roller 6, so that the active rolling roller 5 and the driven rolling roller 6 initially press the dough blank. Then, the electric telescopic component 13 drives the limiting sliding seat 14, so that the electric telescopic component 13 drives the moving rolling roller 16 to approach the driven rolling roller 6 through the limiting sliding seat 14. The first rotation drive component 15 drives the moving rolling roller 16 and the driven rolling roller 6 to rotate synchronously, so that the moving rolling roller 16 and the driven rolling roller 6 cooperate to press the dough to a predetermined thickness. Then, the dough blank is wound around the bottom of the first limiting roller 17, so that the dough blank... The raw material is laid flat on the surface of the material conveying device 2 and moves at a constant speed under the drive of the material conveying device 2, and enters the bottom of the forming roller 7. At the same time, the forming roller 7 drives the built-in fixing frame 76 to rotate axially in the horizontal direction, so that the dough raw material of the forming mold 72 set on the forming roller 7 is pressed into a bun skin. During the process of the forming mold 72 making the dough into a bun skin, when the pusher block 795 is squeezed in the opposite direction by the dough, the pusher block 795 drives the movable rod 794 to squeeze the return spring 793, so that the pusher block 795 contracts. When the forming mold 72 makes the dough into a bun skin, the return spring 793 pushes the pusher block 795 to return to its original position through the movable rod 794, and pushes the bun skin out of the inside of the forming mold 72, so as to facilitate automatic material dropping and avoid the problem of the bun skin easily sticking to the inside of the forming mold 72.

[0063] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
