[0026] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, wherein the drawings form a part of the present application, and are used together with the embodiments of the utility model to explain the principles of the utility model, and are not used to limit the scope of the utility model.

[0027] The rolling device for dough processing in the embodiment relates to the dough shaping equipment technical field, drives the upper roller 220 and the lower roller 210 to move cyclically relative to each other to approach and move away, rolls the dough into the uneven thickness dough skin, and helps the shaped confectionery to form the crisp taste.

[0028] Please refer to Figures 1 to 4 The rolling device for dough processing in the embodiment includes a rack 100, a rolling assembly 200 and a conveying assembly 300, the rack 100 can provide a stable connection and fixing base for the rolling assembly 200 and the conveying assembly 300, and guarantees the stable operation of the equipment. The rolling assembly 200 can roll the dough into the uneven thickness dough skin, and assists the production of the crisp confectionery. The conveying assembly 300 can convey the dough skin to the production line in sequence, and promotes the assembly line production of the confectionery.

[0029] The rolling assembly 200 comprises a rotatable lower roller 210, an upper roller 220, a sliding unit 230, and a driving unit 240. The lower roller 210 and the upper roller 220 form an extrusion space for dough between them, which can extrude the dough into a wrapper. The lower roller 210 is rotationally connected to the rack 100. The relatively rotating lower roller 210 driven by an external force can form a relative feeding trend at the extrusion space, and push the dough to gradually feed the rolling. The upper roller 220 is connected to the rack 100 through the sliding unit 230. The upper roller 220 can move relative to the lower roller 210 along the sliding unit 230, change the distance of the extrusion space, and adjust the thickness of the wrapper rolled into shape. The driving unit 240 comprises two screws 241, which can act on both ends of the upper roller 220 respectively. The two screws 241 can rotate synchronously, drive the upper roller 220 to reciprocate relative to the lower roller 210 at the same feeding rate, and roll the dough. The rolling assembly 200 can produce uneven lines on the wrapper, so that corresponding wrappers can be used to create pastries with a crispy taste.

[0030] The conveying assembly 300 is arranged relative to the lower roller 210. The conveying assembly 300 can receive the wrapper after rolling, and deliver the wrapper to the next process, realizing the automatic production of pastries.

[0031] In the traditional method, the wrapper with uniform thickness needs to be manually rolled and folded repeatedly after rolling. The results of manual operation will fluctuate, and it is difficult to ensure consistency. The roller assembly is controlled mechanically, which not only improves the production efficiency, but also ensures that the thickness change of the wrapper each time is more consistent, ensuring the stability and high quality of the product.

[0032] It should be noted that, please refer to Figure 2 The worm gear mechanism 242 has a self-locking function, that is, in the absence of external force, friction will occur between the worm gear mechanism 242, preventing reverse movement. This feature can effectively avoid reverse vibration or instability of the mechanical system during operation. Therefore, the worm gear mechanism can provide more stable driving for the reciprocating motion of the upper roller, reduce vibration caused by uneven friction or unstable motion, and ensure that the thickness change of the dough after rolling is more uniform and accurate.

[0033] At the same time, the worm gear mechanism can smoothly convert the higher input speed into lower output speed that is not easy to reverse, significantly improving the stability of the transmission process, reducing the negative effects caused by inconsistent speed or impact, and ensuring the stability of the equipment during long-term operation.

[0034] In some embodiments, please refer to Figure 1 and Figure 3The driving unit 240 further comprises two oppositely arranged worm gear mechanisms 242, a transmission rod 243 and a driving member 244. The two ends of the transmission rod 243 are respectively rotatably connected with the input ends of the two worm gear mechanisms 242. The combination of the transmission rod 243 and the worm gear mechanisms 242 further ensures the high-precision control of the driving system. The transmission rod 243 can make the synchronous rotation of the two spiral members 241, thereby realizing the reciprocating movement of the upper roller 220. The synchronism of the upper roller 220 is one of the keys to realize the uneven thickness rolling effect. Once the movement of the upper roller 220 and the lower roller 210 is out of sync, the thickness distribution of the dough cannot achieve the uneven levels in the design.

[0035] Through the forward and reverse rotation control of the transmission rod 243, the system can generate varying pressure areas in different movement cycles, thereby exerting non-uniform pressure on the dough, further enhancing the level effect of the dough and meeting the required uneven thickness characteristics.

[0036] The driving member 244 is rotatably connected with the transmission rod 243 and provides reciprocating forward and reverse rotation, ensuring that the system can move the upper roller 220 with stable periodic movement. The coordinated action of the forward and reverse rotation of the driving member 244 enables the entire system to operate at a predetermined rhythm, thereby maintaining consistency and reducing instability caused by friction.

[0037] As a further embodiment, the driving member 244 is a servo motor. The servo motor has high-precision position control capability and can provide real-time adjustment feedback, which helps to accurately adjust and control the movement of the upper roller 220, ensuring that it can move in the required uneven thickness manner during the rolling process. Through the fine control of the servo motor, the speed, frequency, stroke, etc. of the driving upper roller 220 reciprocating movement can be accurately adjusted, ensuring that the formation of levels in production meets the requirements.

[0038] The driving member 244 is connected with the housing of the worm gear mechanism 242 through a bracket, and the housing and the driving member 244 maintain a relatively stable connection, which can reduce adverse vibrations and noise. The driving member 244 is rotatably connected with the input end of the worm gear mechanism through a coupling, which can ensure that the power is smoothly transmitted to the worm gear system, avoiding equipment failure or production interruption caused by uneven power transmission or excessive resistance. The coupling can also absorb vibrations caused by misalignment of transmission components or changes in load to a certain extent, further ensuring the smoothness of the movement process.

[0039] In some embodiments, please refer to Figure 3 and Figure 4The sliding unit 230 includes a sliding frame 231 and a sliding block 232. The sliding frame 231 is approximately in the shape of a square box, and a relatively sealed space is formed inside the sliding frame 231. The sliding block 232 is arranged in the sealed space. The two sides of the sliding block 232 are provided with clamping grooves that are slidably clamped on the inner wall of the sliding frame 231. The two ends of the upper roller 220 are rotatably connected to the sliding block 232. The sliding block 232 is slidably clamped in the sliding frame 231, and the two ends of the upper roller 220 are rotatably connected to the sliding block 232. The sliding block 232 can drive the upper roller 220 to move along the sliding frame 231 relative to the lower roller 210. The movement of the sliding block is limited by the sliding frame 231, and the movement of the upper roller 220 is no longer a single linear movement, but can be accurately slid along the path of the sliding frame 231. In this way, the upper roller 220 can be accurately reciprocated along a predetermined trajectory, so as to apply the required pressure change to the dough during rolling.

[0040] Referring to Figure 3 The rolling assembly 200 further includes a transmission unit 250. The transmission unit 250 includes a threaded hole 251 arranged on the sliding block 232. The threaded hole 251 can be threadedly connected to the screw 241. The threaded structure can achieve very fine linear adjustment, so that the movement of the sliding block 232 in the sliding frame 231 is more accurate, and the pressure and movement trajectory of the upper roller 220 can be finely adjusted during rolling.

[0041] The threaded transmission mode has high control accuracy and can achieve fine adjustment. The operator can adjust the position of the sliding block 232 by rotating the screw 241, thereby affecting the gap between the upper roller 220 and the lower roller 210, and accurately controlling the thickness of the dough. This fine adjustment capability is particularly suitable for the production of high-precision dough products.

[0042] Compared with other transmission modes, the threaded transmission can provide smoother movement. When the screw 241 rotates, it can smoothly drive the sliding block 232 to move axially smoothly through cooperation with the threaded hole 251, reducing the violent friction or vibration between mechanical components.

[0043] In some embodiments, referring to Figure 1 The rolling assembly 200 further includes a feed hopper 260. The feed hopper 260 is arranged inclined relative to the upper roller 220. The inclined arrangement of the feed hopper 260 relative to the upper roller 220 helps to smoothly feed the dough into the rolling area. This inclination angle can make the dough enter the rolling area more uniformly, avoiding the phenomenon of accumulation, blockage or uneven distribution of the dough when entering the rolling area.

[0044] Compared with the horizontal design, the inclined feed hopper 260 is easier to uniformly send the dough into the device under the action of gravity, avoiding that the excess dough is concentrated in a certain part, thereby affecting the production efficiency and product quality.

[0045] In some embodiments, the conveying assembly 300 comprises a conveyor belt 310 arranged opposite the lower roller 210, and the relative arrangement of the conveyor belt 310 and the lower roller 210 can ensure that the dough is smoothly conveyed to the subsequent processing or handling area after rolling. Through the smooth movement of the conveyor belt 310, the dough will not be damaged due to excessive friction or too slow conveying speed.

[0046] As a further embodiment, the conveyor belt 310 is provided with a roller 320 for pressing patterns on the dough sheet. By pressing patterns on the dough sheet through the roller 320, the dough sheet surface can have unique patterns and textures, not only improving the visual effect of the finished product, but also enhancing its market appeal. The fine design on the appearance of the product is often one of the important factors for consumers to choose, therefore, the pattern design can make the flour product more visually exquisite, and improve the brand image.

[0047] The patterns pressed by the roller 320 form tiny concave-convex structures on the surface of the dough sheet, which helps the dough sheet to expand more uniformly during baking. Hot air can flow more easily in the gaps of the patterns, thereby helping the dough sheet to expand uniformly during baking, ensuring the crisp taste and clear layers of the product.

[0048] Work flow: First, start the driving member 244 to make the transmission rod 243 drive the two worm gear mechanisms 242 to rotate reciprocatingly, thereby driving the transmission rod 243 to rotate forward and reverse. Then, put the dough into the feed hopper 260, and drive the lower roller 210 to rotate. Next, the upper roller 220 moves reciprocatingly along the sliding frame 231 relative to the lower roller 210 to roll the dough into a dough sheet with uneven thickness. Finally, the dough sheet is conveyed along the conveying assembly 300 to the subsequent process.

[0049] The above describes only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the present application.
