Description

Technical Field

[0001] This application relates to bread shaping, and more particularly to a manual bread shaping machine for laboratory use. Background Technology

[0002] Currently, in the baking industry, especially in small R&D labs, bread shaping typically relies on manual labor. While this method offers high flexibility, adapting to various bread shapes and sizes, it also has significant drawbacks, such as high labor intensity, low efficiency, inconsistent product quality, and impact on experimental results. Although some automated bread shaping equipment exists on the market, the long return on investment cycle for small and medium-sized labs hinders its widespread adoption. Furthermore, due to its high degree of automation, the operation and adjustment of this equipment are relatively complex, requiring professional training and technical support, which further limits its widespread application in small environments.

[0003] While existing manual bread shaping methods are flexible and versatile, they are inefficient and difficult to maintain consistent quality, especially prone to deviations during experimental operations. Although automated shaping equipment improves efficiency, its high cost and complex operation make it unsuitable for laboratory use. To address these issues, a manual bread shaping machine for laboratory use is proposed. Utility Model Content

[0004] The purpose of this application is to provide a manual bread shaping machine for laboratory use, which has the advantages of low cost, simple operation, high efficiency and consistency, and solves the problems of low work efficiency and difficulty in maintaining stable quality in existing manual shaping methods, as well as the high cost and complicated operation of automated shaping equipment.

[0005] This application provides a manual bread shaping machine for laboratory use, employing the following technical solution: It includes a base, a housing fixedly connected to the top of the base, two rotating rods rotatably connected inside the housing via bearings, rotating cylinders fixedly connected to the surfaces of the rotating rods, a conveyor belt drivingly connected to the surfaces of the two rotating cylinders, a connecting plate and a sliding box fixedly connected to the top of the housing, two fixed cylinders fixedly connected inside the connecting plate, sliding rods slidably connected inside the fixed cylinders, U-shaped plates fixedly connected to the bottom ends of the two sliding rods, a pressing roller rotatably connected inside the U-shaped plate, two sliders slidably connected inside the sliding box, a guide plate fixedly connected to the bottom of the sliders, an adjusting box fixedly connected to the top of the U-shaped plate, two limiting plates slidably connected inside the adjusting box, the limiting plates slidably connected to the surfaces of the pressing rollers, a guide plate and a push rod fixedly connected to opposite sides of the limiting plates respectively, a fixed frame fixedly connected to the back of the guide plate, the push rod being within the fixed frame, and an inclined plate and an auxiliary forming track fixedly connected to opposite sides inside the housing respectively, the bottom of the inclined plate and the bottom of the auxiliary forming track overlapping the top of the conveyor belt.

[0006] By adopting the above technical solution, the conveyor belt ensures smooth dough transport, avoiding deformation caused by manual handling. The pressing rollers compress the dough during movement, and the push rod and fixed frame limit the movement, while the slider adjusts the distance between the two guide plates, enabling synchronous displacement and guiding the dough precisely into the shaping area, reducing deviation. The inclined plate and auxiliary forming track overlap the conveyor belt to form a progressive shaping path, simulating manual rounding and improving dough firmness. Integrating the core processes of conveying, rolling, and rounding, this solution replaces traditional segmented operations, shortens processing time, and is cost-effective and easy to operate.

[0007] Preferably, one end of the rotating rod rotates through the side of the housing and is fixedly connected to a first gear. A fixed shell is fixedly connected to the side of the housing. A transmission rod is tightly nested in the side of the housing via a bearing. A second gear is fixedly connected to the surface of the transmission rod. The first gear and the second gear are both inside the fixed shell and mesh with each other. One end of the transmission rod rotates through the side of the fixed shell and is fixedly connected to a rotating handle.

[0008] By adopting the above technical solution, and by setting a rotating handle, people can rotate the handle, and then through the meshing of the first gear and the second gear, the torque of the manually rotated handle can be transmitted to the rotating rod, which can realize the operation of the conveyor belt without electric drive, and is suitable for small-batch operation in the laboratory.

[0009] Preferably, a threaded cap is fixedly connected to the top of the connecting plate, an adjusting bolt is threadedly connected inside the threaded cap, a top plate is fixedly connected to the bottom of the adjusting bolt, and the bottom of the top plate overlaps the top of the U-shaped plate;

[0010] By adopting the above technical solution, and by setting an adjusting bolt, people can rotate the adjusting bolt to push the top plate to move, thereby controlling the pressure under the U-shaped plate. This can adapt to the rolling requirements of doughs with different hardness and avoid excessive compression that could damage the dough structure.

[0011] Preferably, a connecting spring is fixedly connected to the top of the inside of the fixed cylinder, a movable plate is fixedly connected to the bottom of the connecting spring, and the bottom of the movable plate is fixedly connected to the top of the slide rod;

[0012] By adopting the above technical solution and setting a connecting spring, the connecting spring drives the movable plate and the slide bar, so that the pressing roller has a vertical elastic stroke, which can compensate for the fluctuation of dough thickness and ensure the uniformity of rolling.

[0013] Preferably, two fixed plates are fixedly connected inside the adjustment box, and a rotating shaft is tightly nested between the two fixed plates via bearings. A worm gear is fixedly connected to the surface of the rotating shaft. A rotating rod is tightly nested at the top of the adjustment box via bearings. A worm is fixedly connected to the surface of the rotating rod. The worm and the worm gear mesh with each other. A knob is fixedly connected to the top of the rotating rod.

[0014] By adopting the above technical solution, and by setting a knob, people can drive the worm gear to rotate by rotating the knob. This can convert the rotational motion into the horizontal displacement of the limit plate, thereby realizing the adjustment of the distance between the two limit plates. At the same time, the self-locking characteristic of the worm gear can prevent loosening in the working state.

[0015] Preferably, threaded rods are fixedly connected to both ends of the rotating shaft, the shaft ends of the threaded rods are rotatably connected to the inner side of the adjusting box, a threaded cylinder is threadedly connected to the surface of the threaded rods, and the limiting plate is fixedly connected to the surface of the threaded cylinder.

[0016] By adopting the above technical solution, and by setting up a threaded rod and a threaded cylinder transmission, the threaded rod can be driven by a rotating shaft to make the threaded cylinders on both sides move synchronously, thus ensuring the symmetrical movement of the limit plate.

[0017] Preferably, handles are fixedly connected to both opposite sides of the housing;

[0018] By adopting the above technical solution and setting handles, a stable grip point can be provided, which facilitates equipment handling and stability control during operation, and is especially suitable for frequent laboratory relocation scenarios.

[0019] Preferably, each of the four corners of the base is fixedly connected to a support foot;

[0020] By adopting the above technical solution and setting support feet, the four-corner support design can distribute the equipment load, reduce the impact of vibration on the shaping accuracy, and also avoid slippage caused by direct contact with the table surface.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This laboratory manual bread shaping machine, by setting up a conveyor belt, ensures the smooth transport of dough, avoiding deformation caused by manual handling. By setting up a dough pressing roller, the dough can be squeezed during movement. Then, by using a push rod and a fixed frame for limiting, and then linking a slider, the distance between two guide plates can be adjusted to achieve synchronous displacement of the two guide plates. This guides the dough precisely into the shaping area, reducing deviation. By setting up an inclined plate and an auxiliary forming track, the conveyor belt can be connected to form a progressive shaping path, which can simulate the hand rolling action, improve the compactness of the dough. It integrates the core processes of conveying, rolling, and rounding, and can replace traditional segmented operations, shorten processing time, and is low in cost and easy to operate.

[0023] 2. This laboratory manual bread shaping machine features a rotary handle. Rotating the handle transmits torque to a rotating rod via the meshing of a first and second gear, enabling a conveyor belt that operates without electricity. Suitable for small-batch laboratory operations, this machine utilizes an adjusting bolt to move the top plate, controlling the pressure of the U-shaped plate and adapting to doughs of varying hardness. This prevents excessive compression that could damage the dough structure. A connecting spring drives a movable plate and a sliding rod, providing the pressing roller with vertical elastic stroke to compensate for dough thickness fluctuations and ensure uniform pressing. A knob, when rotated, drives a worm gear to rotate a worm wheel, converting rotational motion into horizontal displacement of the limiting plates. This allows for distance adjustment between the two limiting plates. During dough transport, the aforementioned worm gear adjustment and manual drive ensure consistent dough shape.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0034] Example 1: A manual bread shaping machine for laboratory use, referring to... Figure 1 , Figure 2 and Figure 3The system includes a base 1, a housing 2 fixedly connected to the top of the base 1, two rotating rods 203 rotatably connected inside the housing 2 via bearings, rotating cylinders 204 fixedly connected to the surface of the rotating rods 203, and a conveyor belt 205 drivingly connected to the surface of the two rotating cylinders 204. A connecting plate 207 and a sliding box 208 are fixedly connected to the top of the housing 2. Two fixed cylinders 2010 are fixedly connected inside the connecting plate 207. Sliding rods 2011 are slidably connected inside the fixed cylinders 2010. U-shaped plates 2012 are fixedly connected to the bottom ends of the two sliding rods 2011. The U-shaped plate 2012 has a rotatably connected pressing roller 2013 inside. Two sliders 2025 are slidably connected inside the sliding box 208. A guide plate 2026 is fixedly connected to the bottom of each slider 2025. An adjusting box 2034 is fixedly connected to the top of the U-shaped plate 2012. Two limiting plates 2023 are slidably connected inside the adjusting box 2034. The limiting plates 2023 are slidably connected to the surface of the pressing roller 2013. A guide plate 2037 and a push rod 2024 are fixedly connected to opposite sides of the limiting plates 2023, respectively. A guide plate 2026 is fixedly connected to the back of the guide plate 2026. The fixed frame 2027 and the push rod 2024 are located inside the fixed frame 2027. An inclined plate 206 and an auxiliary forming track 209 are fixedly connected to opposite sides inside the housing 2. The bottoms of the inclined plate 206 and the auxiliary forming track 209 overlap the top of the conveyor belt 205. By setting the conveyor belt 205, the dough can be transported smoothly, avoiding deformation caused by manual handling. By setting the dough pressing roller 2013, the dough can be squeezed during movement, and then pushed by the push rod 2024 and the fixed frame 2027... The limit is set, and then the linkage slider 2025 can adjust the distance between the two guide plates 2026, which can realize the synchronous displacement of the two guide plates 2026. This can guide the dough to enter the shaping area accurately and reduce deviation. By setting the inclined plate 206 and the auxiliary forming track 209, the conveyor belt 205 can be connected to form a progressive shaping path, which can simulate the manual rolling action, improve the compactness of the dough, and integrate the core processes of conveying, rolling and rounding. This can replace the traditional segmented operation, shorten the processing time, and is low in cost and easy to operate.

[0035] Please see Figure 3 and Figure 5A rotating rod 203 has one end that rotates through the side of the housing 2 and is fixedly connected to a first gear 2017. A fixed housing 201 is fixedly connected to the side of the housing 2. A transmission rod 2018 is tightly nested in the side of the housing 2 via bearings. A second gear 2019 is fixedly connected to the surface of the transmission rod 2018. Both the first gear 2017 and the second gear 2019 are inside the fixed housing 201 and mesh with each other. One end of the transmission rod 2018 rotates through the side of the fixed housing 201 and is fixedly connected to a rotating handle 2020. By setting the rotating handle 2020, people can rotate the rotating handle 2020, and then through the meshing of the first gear 2017 and the second gear 2019, the torque of the manually operated rotating handle 2020 can be transmitted to the rotating rod 203, which can realize the operation of the conveyor belt 205 without electric drive, suitable for small-batch operation in the laboratory. A threaded cap 2014 is fixedly connected to the top of the connecting plate 207. The roll 2013 is threaded with an adjusting bolt 2015, and a top plate 2016 is fixedly connected to the bottom of the adjusting bolt 2015. The bottom of the top plate 2016 overlaps the top of the U-shaped plate 2012. By rotating the adjusting bolt 2015, the top plate 2016 can be moved, thereby controlling the downward pressure of the U-shaped plate 2012. This allows it to adapt to the rolling requirements of doughs with different hardness, avoiding excessive compression that could damage the dough structure. A connecting spring 2021 is fixedly connected to the top of the fixed cylinder 2010. A movable plate 2022 is fixedly connected to the bottom of the connecting spring 2021. The bottom of the movable plate 2022 is fixedly connected to the top of the slide rod 2011. By setting the connecting spring 2021, the connecting spring 2021 drives the movable plate 2022 and the slide rod 2011, giving the pressing roller 2013 a vertical elastic stroke. This can compensate for fluctuations in dough thickness and ensure uniform rolling.

[0036] Please see Figure 4 and Figure 6The adjusting box 2034 has two fixed plates 2028 internally connected. A rotating shaft 2029 is tightly nested between the two fixed plates 2028 via bearings. A worm gear 2036 is fixedly connected to the surface of the rotating shaft 2029. A rotating rod 2031 is tightly nested at the top of the adjusting box 2034 via bearings. A worm 2033 is fixedly connected to the surface of the rotating rod 2031, and the worm 2033 meshes with the worm gear 2036. A knob 2032 is fixedly connected to the top of the rotating rod 2031. By rotating the knob 2032, the worm 2033 can be driven to rotate, thus converting the rotational motion into the movement of the limiting plate 2023. The horizontal displacement allows for adjustment of the distance between the two limiting plates 2023. Simultaneously, the self-locking characteristic of the worm gear 2036 prevents loosening during operation. Threaded rods 2030 are fixedly connected to both ends of the rotating shaft 2029. The shaft ends of the threaded rods 2030 are rotatably connected to the inner side of the adjusting box 2034. A threaded cylinder 2035 is threadedly connected to the surface of the threaded rods 2030. The limiting plates 2023 are fixedly connected to the surface of the threaded cylinders 2035. By setting the transmission between the threaded rods 2030 and the threaded cylinders 2035, the threaded rods 2030, driven by the rotating shaft 2029, can cause the threaded cylinders 2035 on both sides to move synchronously, ensuring symmetrical movement of the limiting plates 2023.

[0037] Please see Figure 1 and Figure 2 The housing 2 has handles 202 fixedly connected to both sides. By setting handles 202, a stable grip point can be provided, which is convenient for equipment handling and stability control during operation. It is especially suitable for frequent moving scenarios in the laboratory. The base 1 has support feet 101 fixedly connected to the four corners of the bottom. By setting support feet 101, the four-corner support design can distribute the load of the equipment, reduce the impact of vibration on the shaping accuracy, and at the same time, avoid sliding caused by direct contact with the table surface.

[0038] The implementation principle of this application embodiment is as follows:

[0039] In use, the dough is placed inside the shell 2. After placement, the handle 2020 is turned to rotate the second gear 2019 and the transmission rod 2018. Through the meshing of the first gear 2017 and the second gear 2019, the rotating rod 203 and the rotating cylinder 204 are rotated, which moves the conveyor belt 205 and the dough. Under the action of the guide plate 2037, the dough is centered. Under the action of the pressing roller 2013, the dough is pressed and shaped. The extruded dough is limited by the two guide plates 2026 and can move to the side of the auxiliary forming track 209. Under the action of the auxiliary forming track 209, the dough can be simulated by hand rolling, which improves the compactness of the dough. After shaping, the shaped dough is taken out and the next operation cycle can be continued.

[0040] When the height of the pressing roller 2013 needs to be adjusted, the adjusting bolt 2015 can be rotated to push the top plate 2016 to move, thereby controlling the downward pressing position of the U-shaped plate 2012. This can adapt to the rolling requirements of doughs with different hardness and facilitate the adjustment of the required dough thickness. By setting the knob 2032, rotating the knob 2032 can drive the worm gear 2033 to rotate the worm wheel 2036, which can convert the rotational motion into the horizontal displacement of the limiting plate 2023. This allows for the adjustment of the distance between the two limiting plates 2023, making it convenient to adjust the width of the dough.

[0041] This device allows for precise control and ease of operation of dough shaping through manual adjustment, making it particularly suitable for research laboratories, small baking workshops, and other similar settings. By simplifying traditional production line equipment into a desktop-operable tool, it offers advantages such as low cost and ease of operation.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
