Description

Technical Field

[0001] This utility model relates to the field of dough rolling technology, specifically a multi-stage rolling and shaping device for precise control of mooncake dough thickness. Background Technology

[0002] In the food processing industry, especially in mooncake making, controlling the thickness of the mooncake dough is a key factor in ensuring the taste and appearance quality of the mooncakes. Traditional mooncake dough making often relies on hand-rolling, a method that is not only inefficient but also makes it difficult to guarantee the uniformity of dough thickness, thus affecting the final quality of the mooncakes. With the development of technology and the advancement of industrialized production, automation and mechanization have become important trends in the food processing industry. In the field of mooncake making, various automated equipment has emerged to improve production efficiency and product quality.

[0003] However, existing equipment still has many shortcomings in controlling the thickness of mooncake dough. Mooncake dough is usually made from a mixture of flour, sugar, and oil, and its material properties mean that the dough undergoes both plastic and elastic deformation during rolling. Traditional automated equipment often uses a single rolling process to roll the dough. While this method can achieve initial shaping of the dough, it is difficult to guarantee the uniformity of its thickness. Due to the uneven pressure distribution during rolling, some areas become too thin, while others are relatively thick, seriously affecting the final quality of the mooncake. In addition, single rolling also leads to a significant increase in the length of the dough. This is because the dough undergoes plastic flow under rolling pressure, causing it to stretch along its length. This change in length not only causes inconvenience in subsequent processing but may also affect the accuracy of dough conveying and positioning, further reducing the production efficiency of mooncakes. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage roller pressing and shaping device for precise control of mooncake dough thickness. The device uses multi-stage roller pressing technology to gradually reduce the thickness of the dough, and uses a thickness detection device to detect the thickness of the dough in real time, control the gap between the upper and lower rollers, and adjust the tension of the dough through a tension adjustment component, thereby improving the uniformity of the dough thickness.

[0005] To address the problems in existing technologies, this utility model provides a multi-stage roller pressing and shaping device for precise control of mooncake dough thickness. The device includes a main body, on which a first-stage roller pressing assembly, a second-stage roller pressing assembly, and a third-stage roller pressing assembly are sequentially arranged along the dough conveying direction. Each of the first-stage, second-stage, and third-stage roller pressing assemblies includes a dough pressing mechanism. Each dough pressing mechanism has a lower roller and an upper roller for squeezing the dough. The gap between the lower roller and the upper roller in the first-stage, second-stage, and third-stage roller pressing assemblies decreases sequentially. Tension adjustment components for adjusting the dough tension are provided between the first-stage and second-stage roller pressing assemblies and between the second-stage and third-stage roller pressing assemblies. A thickness detection device for detecting the dough thickness is also installed in each of the first-stage, second-stage, and third-stage roller pressing assemblies.

[0006] Preferably, the tension adjustment assembly includes a support plate mounted on the main body, a fixed roller is laterally arranged near the center of the support plate, the tension adjustment assembly includes movable rollers arranged on both sides of the fixed roller, and the position of the movable rollers can be adjusted, the tension adjustment assembly also includes an angle adjustment mechanism that can drive the movable rollers to change position.

[0007] Preferably, the support plate is further provided with a limiting groove for guiding the movable roller, and both ends of the movable roller can slide in the limiting groove, which is an arc-shaped groove.

[0008] Preferably, the angle adjustment mechanism in the tension adjustment assembly includes a transmission rod rotatably disposed on the outer side, with one end of the transmission rod being movably connected to one end of the movable roller. The angle adjustment mechanism also includes a transmission block coaxially connected to the transmission rod and a first telescopic drive member disposed on the main body, with the output end of the first telescopic drive member being rotatably connected to the transmission block.

[0009] Preferably, the dough rolling mechanism includes side plates fixed to both sides of the top of the main body, with the lower roller rotatably disposed between the two side plates and the upper roller capable of moving up and down between the two side plates. The top of each side plate is also fixed with a second telescopic drive member for driving the upper roller to move up and down.

[0010] Preferably, the dough rolling mechanism further includes a transmission component that enables the lower roller and the upper roller to rotate in opposite directions.

[0011] Preferably, the transmission assembly includes a rotary drive member disposed on a side plate, the output end of the rotary drive member being connected to a sixth gear, and the transmission assembly also includes a fifth gear fixed to one end of the lower roller, the fifth gear meshing with the sixth gear.

[0012] Preferably, the transmission assembly includes a first gear fixed to the other end of the lower roller and a fourth gear fixed to one end of the upper roller. The transmission assembly also includes a second gear rotatably disposed on the outside of another side plate, which meshes with the first gear.

The transmission assembly also includes a second connecting rod connected to the first connecting rod, and one end of the second connecting rod is connected to the end of the upper roller.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. This application uses a thickness detection device to detect the thickness of the dough in real time, and drives the upper roller to move via a second telescopic drive component to adjust the thickness of the dough. Furthermore, the system includes multiple rolling components, including a first-stage rolling component, a second-stage rolling component, and a third-stage rolling component. The gap between the lower and upper rollers in these components gradually decreases, causing the dough thickness to gradually decrease after multiple stages of rolling, thus avoiding the uneven thickness problem caused by single-stage extrusion molding in traditional devices.

[0015] 2. During the dough extrusion process, the length of the dough increases and it elongates. Therefore, the rotational speed between the lower and upper rollers in the first, second, and third stage roller pressing assemblies gradually increases to maintain the length of the dough. At the same time, in conjunction with the action of the movable rollers, the transmission block is moved by the first telescopic drive component, which in turn causes the transmission rod to move the movable rollers. This changes the distance between the two sets of movable rollers and the fixed rollers, achieving dynamic adjustment of the dough tension and thus improving the uniformity of the dough thickness.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-6 As shown, this utility model provides a multi-stage roller pressing and shaping device for precise control of mooncake dough thickness, including a main body 1. A first-stage roller pressing assembly 2, a second-stage roller pressing assembly 3, and a third-stage roller pressing assembly 4 are sequentially arranged on the main body 1 along the dough conveying direction. Each of the first-stage roller pressing assembly 2, second-stage roller pressing assembly 3, and third-stage roller pressing assembly 4 is equipped with a dough pressing mechanism 7. The dough pressing mechanism 7 has a lower roller 72 and an upper roller 73 for squeezing the dough. The gap between the lower roller 72 and the upper roller 73 in the first-stage roller pressing assembly 2, second-stage roller pressing assembly 3, and third-stage roller pressing assembly 4 decreases sequentially. Tension adjustment components 5 for adjusting the tension of the dough are provided between the first-stage roller pressing assembly 2 and the second-stage roller pressing assembly 3, and between the second-stage roller pressing assembly 3 and the third-stage roller pressing assembly 4. A thickness detection device 6 for detecting the dough thickness is also installed in the first-stage roller pressing assembly 2, second-stage roller pressing assembly 3, and third-stage roller pressing assembly 4.

[0025] The dough first enters the first-stage rolling assembly 2, where the thickness is initially adjusted by the squeezing action of the lower roller 72 and the upper roller 73. Next, the dough enters the tension adjustment assembly 5 for tension adjustment to ensure flatness. Then, the dough enters the second-stage rolling assembly 3 for further rolling and thickness adjustment. Similarly, the dough undergoes further tension adjustment by the tension adjustment assembly 5 between the second-stage and third-stage rolling assemblies 3 and 4. Finally, the dough enters the third-stage rolling assembly 4 for final rolling and precise thickness control. Throughout the entire process, the thickness detection device 6 monitors the dough thickness in real time to ensure product quality stability and consistency.

[0026] The upper roller 73 is moved by the second telescopic drive component 75 to adjust the thickness of the dough. In addition, the system is equipped with multiple rolling components, including a first-stage rolling component 2, a second-stage rolling component 3, and a third-stage rolling component 4. The gap between the lower roller 72 and the upper roller 73 in these components gradually decreases, so that the thickness of the dough gradually decreases after passing through multiple stages of rolling, thereby avoiding the uneven thickness problem caused by single extrusion molding in traditional devices.

[0027] The tension adjustment assembly 5 includes a support plate 51 mounted on the main body 1. A fixed roller 52 is laterally arranged near the center of the support plate 51. The tension adjustment assembly 5 includes movable rollers 53 arranged on both sides of the fixed roller 52. The position of the movable rollers 53 can be adjusted. The tension adjustment assembly 5 also includes an angle adjustment mechanism that can drive the movable rollers 53 to change their position.

[0028] The support plate 51 is also provided with a limiting groove 511 for guiding the movable roller 53, and both ends of the movable roller 53 can slide in the limiting groove 511. The limiting groove 511 is an arc groove. The angle adjustment mechanism in the tension adjustment assembly 5 includes a transmission rod 54 rotatably disposed on the outside, and one end of the transmission rod 54 is movably connected to one end of the movable roller 53. The angle adjustment mechanism also includes a transmission block 55 coaxially connected to the transmission rod 54 and a first telescopic drive member 56 disposed on the main body 1. The output end of the first telescopic drive member 56 is rotatably connected to the transmission block 55.

[0029] When the dough tension needs to be adjusted, the first telescopic drive 56 is activated. The output end of the first telescopic drive 56 pushes or pulls the transmission block 55, which transmits force to the movable roller 53 via the transmission rod 54. Guided by the limiting groove 511, the movable roller 53 slides within the limiting groove 511, thereby changing the relative position between the movable roller 53 and the fixed roller 52. By adjusting the position of the movable roller 53, the dough tension can be controlled, ensuring the flatness and thickness consistency of the dough.

[0030] The dough rolling mechanism 7 includes side plates 71 fixed to both sides of the top of the main body 1, with a lower roller 72 rotatably disposed between the two side plates 71 and an upper roller 73 capable of moving up and down between the two side plates 71. A second telescopic drive member 75 for driving the upper roller 73 to move up and down is also fixed to the top of each side plate 71. The dough rolling mechanism 7 also includes a transmission assembly 74 capable of causing the lower roller 72 and the upper roller 73 to rotate in opposite directions. The transmission assembly 74 includes a rotary drive member 747 disposed on one side plate 71, with a sixth gear 749 connected to the output end of the rotary drive member 747. The transmission assembly 74 also includes a fifth gear 748 fixed to one end of the lower roller 72, the fifth gear 748 meshing with the sixth gear 749. The transmission assembly 74 includes a first gear 741 fixed to the other end of the lower roller 72 and a fourth gear 744 fixed to one end of the upper roller 73. The transmission assembly 74 also includes a second gear 742 rotatably disposed on the outside of another side plate 71, which meshes with the first gear 741. The transmission assembly 74 includes a first connecting rod 745, one end of which is connected to the shaft on the second gear 742. A third gear 743 is rotatably connected to one end of the first connecting rod 745, which meshes with the fourth gear 744. The transmission assembly 74 also includes a second connecting rod 746 connected to the first connecting rod 745, and one end of the second connecting rod 746 is connected to one end of the upper roller 73.

[0031] In operation, when the rotary drive 747 is working, its output end drives the sixth gear 749 to rotate. The sixth gear 749 meshes with the fifth gear 748, driving the lower roller 72 to rotate. The rotation of the lower roller 72 is transmitted to the second gear 742 through the first gear 741, which in turn drives the third gear 743 to rotate. The third gear 743 meshes with the fourth gear 744, driving the upper roller 73 to rotate in the opposite direction to the lower roller 72. This allows the dough to be conveyed. When the position of the upper roller 73 changes, the first connecting rod 745 and the second connecting rod 746 move to ensure that the third gear 743 and the fourth gear 744 are always meshed, maintaining power transmission.

[0032] The first telescopic drive 56 moves the transmission block 55, which in turn causes the transmission rod 54 to move the movable roller 53. This causes the distance between the two sets of movable rollers 53 and the fixed roller 52 to change, thereby dynamically adjusting the tension of the dough and improving the uniformity of the dough thickness.

[0033] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
