Abstract
Description
Technical Field
[0001] This application relates to the field of food processing technology, and in particular to a double-layer skin composite forming device. Background Technology
[0002] In the production of dough-based foods, automated production has enabled large-scale, standardized food manufacturing, meeting the growing market demand. Among the key steps in the food processing is the flattening and rolling of the dough. This process helps optimize the texture and structure of the dough, ensuring even gas distribution within it, thereby improving the expansion properties and appearance of the food and enhancing consumer satisfaction.
[0003] To achieve dough sheet rolling, the industry typically employs specialized rolling devices. These devices generally consist of a frame as the basic support structure, upon which a conveyor belt is mounted to transport the dough sheets. Rolling rollers are rotatably mounted on the frame and driven by a motor. The rolling rollers are positioned at an angle above the conveyor belt. As the dough sheets are placed on the conveyor belt and transported to the rolling rollers, the angled rollers create a progressive contact area between the roller surface and the dough sheet. The leading edge of the dough sheet is lifted by the roller surface and then spontaneously bends into a small-radius loop within the gap between the roller surface and the conveyor belt. As dough sheets continue to be fed in, the roll core rolls along a spiral trajectory under the pressure of the roller surface, and the radius of curvature of the newly rolled dough sheets gradually increases, thus completing the dough sheet rolling process.
[0004] Current methods of rolling dough have a significant problem: while consistent dough thickness in automated production may seem to follow standardization, the final rolled portion, being the outermost layer of the rolled edge, exhibits a noticeable thickness abrupt change when its original thickness is superimposed on the inner layers. This causes the final rolled portion to easily curl up. Furthermore, during subsequent baking, the dough is prone to delamination, affecting the overall quality of the food. Utility Model Content
[0005] To reduce the loosening of the dough during rolling, this application provides a double-layer dough composite forming device.
[0006] The double-layer leather composite molding device provided in this application adopts the following technical solution:
[0007] A double-layer leather composite forming device includes a first rolling mechanism. The first rolling mechanism includes a first frame, a first conveying structure mounted on the first frame, a first side roller structure, and a first edge-rolling structure. The first edge-rolling structure is used to perform edge-rolling operations on the leather. The leather has a pre-rolled portion and a final-rolled portion along the edge-rolling direction. The first edge-rolling structure starts from the pre-rolled portion and moves towards the final-rolled portion.
[0008] The first side roller structure is used to apply pressure to the final roll portion of the dough. The first side roller structure includes a first pressure roller, a first lifting assembly, and a first mounting shaft. The first lifting assembly is mounted on the first frame. The first mounting shaft is used to connect the first pressure roller and the first lifting assembly. The first pressure roller is used to abut against the surface of the final roll portion of the dough.
[0009] By adopting the above technical solution, the first pressure roller uniformly thins one side of the dough, and after reducing the thickness of the dough, its extensibility and flexibility are optimized. When rolling, the thinner dough is easier to fit tightly, reducing the amount of air entering the gap between the layers, thereby avoiding wrinkles or bulges caused by residual air, thus reducing the occurrence of dough delamination during baking. It also makes the final rolled part of the dough transition from convex to smooth, reducing the thickness difference and lowering the possibility of the final rolled part of the dough lifting.
[0010] By setting the first lifting component, the gap between the first pressure roller and the first conveying structure can be changed, so as to adjust the pressing thickness of the dough according to the dough thickness and improve the bonding effect on the outer side after the dough is rolled up.
[0011] Optionally, the first lifting assembly includes a lifting plate and a first bolt, and the first mounting shaft is mounted on the lifting plate; the lifting plate has an oblong hole, the first bolt passes through the oblong hole and is connected to the first frame, and the lifting plate is clamped between the head of the first bolt and the first frame.
[0012] By adopting the above technical solution, the height of the first pressure roller can be adjusted by adjusting the position of the first bolt in the waist-shaped hole, so as to meet the needs of rolling up sheets of different thicknesses.
[0013] Optionally, the first lifting assembly has a movable hole, and one end of the first mounting shaft passes through the movable hole; the first lifting assembly is provided with a fastener, which is used to fix the first mounting shaft to the first lifting assembly.
[0014] By adopting the above technical solution, the position of the first pressure roller can be changed by sliding the first mounting shaft onto the first lifting assembly. This not only adjusts the thickness of the dough sheet but also allows adjustment of the first pressure roller's position based on the original width of the dough sheet, improving the practicality of the first side roller structure. Furthermore, fasteners can be used to fix the first mounting shaft to the first lifting assembly, ensuring a stable position for the first pressure roller.
[0015] Optionally, the fastener includes a second bolt, the first lifting assembly has a threaded hole communicating with the movable hole, and the second bolt is threadedly installed in the threaded hole to abut against the outer wall of the first mounting shaft.
[0016] By adopting the above technical solution, using the second bolt threaded into the threaded hole and abutting against the outer wall of the first mounting shaft as a fastener, the first mounting shaft can be conveniently and firmly fixed to the first lifting assembly, thereby stably fixing the position of the first pressure roller.
[0017] Optionally, the fastener includes a spring and a plug rod. The inner wall of the movable hole is provided with a sliding groove, and the plug rod is slidably installed in the sliding groove. The first mounting shaft is provided with a plurality of plug grooves for the plug rod to be inserted into. The spring force is used to drive the plug rod to be inserted into the plug groove under normal conditions.
[0018] By adopting the above technical solution, the spring force is used to insert the plug rod into the plug groove of the first mounting shaft under normal conditions, thereby fixing the first mounting shaft and the first lifting assembly, and the position of the first pressure roller can be flexibly adjusted; the structure is simple and improves the adjustment efficiency of the first pressure roller.
[0019] Optionally, the end of the insertion slot away from the movable hole is connected to the outer wall of the first lifting assembly, and an anti-detachment plate for connecting with the insertion rod is provided on the outside of the first lifting assembly; the spring is sleeved on the outer wall of the insertion rod, and the two ends of the spring are respectively connected to the anti-detachment plate and the first lifting assembly.
[0020] By adopting the above technical solution, since the end of the insertion slot away from the movable hole is connected to the outer wall of the first lifting component, the insertion slot can be easily processed and manufactured; at the same time, an anti-detachment plate connected to the insertion rod is set on the outside of the first lifting component, and a spring is sleeved on the outer wall of the insertion rod and its two ends are respectively connected to the anti-detachment plate and the first lifting component. This structure facilitates the installation and assembly of each component and has the advantage of being easy to manufacture.
[0021] Optionally, it also includes a second winding mechanism, wherein the rolled edge formed on the surface of the second winding mechanism is wrapped inside the rolled edge formed on the surface of the first rolled edge mechanism; the second winding mechanism includes a second frame, a second conveying structure mounted on the second frame, a second side roller structure, and a second winding structure, wherein the second side roller structure is used to apply pressure to the final winding portion of the surface.
[0022] By adopting the above technical solution, adding a second rolling mechanism can transport the rolled dough to the first rolling mechanism, which can make the finished product have two kinds of dough, thus improving the texture of the bread.
[0023] Optionally, the second frame is provided with a third side roller assembly, which is used to apply pressure to the pre-wound portion of the dough; the outer diameter of the third pressure roller of the third side roller assembly is smaller than the outer diameter of the second pressure roller of the second side roller assembly.
[0024] By adopting the above technical solution, and by setting up a third side roller assembly, the third side roller and the second side roller are conducive to compacting the side edges of the dough, reducing the possibility of side tearing; and by making the outer diameter of the second side roller larger than the outer diameter of the third side roller, the thickness of the two sides of the dough can vary, which is conducive to rolling up and bonding the dough into a roll.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. The first pressure roller evenly thins one side of the dough, reducing its thickness and optimizing its extensibility and flexibility. When rolled, the thinner dough is easier to adhere tightly, reducing the amount of air entering the gaps between the layers and thus avoiding wrinkles or bulges caused by residual air. This reduces the possibility of dough delamination during baking. It also makes the final rolled part of the dough transition from a raised area to a smooth one, reducing the thickness difference and lowering the possibility of the final rolled part of the dough lifting.
[0027] 2. By setting the first lifting component, the gap between the first pressure roller and the first conveying structure can be changed, so as to adjust the pressing thickness of the dough according to the dough thickness and improve the bonding effect of the outer side after the dough is rolled.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0034] Example 1:
[0035] This application discloses a double-layer leather composite molding device.
[0036] Reference Figure 1 A double-layer leather composite forming device includes a first rolling mechanism 1 and a second rolling mechanism 5. The leather has a pre-rolled portion and a final rolled portion along the rolling edge direction. Both the first rolling mechanism 1 and the second rolling mechanism 5 are used to start from the pre-rolled portion of the leather and advance towards the final rolled portion to perform the rolling edge operation. In the rolling edge process, the first rolling edge mechanism wraps the rolled edge formed by the second rolling edge mechanism into its own rolling edge structure.
[0037] The first edge-rolling mechanism includes a first frame 11, a first conveying structure 2, a first side roller structure 3, and a first edge-rolling structure 4 installed on the first frame 11. The first conveying structure 2 is used to convey the dough. The first conveying structure 2 is prior art and will not be described in detail here. The first side roller structure 3 is installed at the front end of the first edge-rolling mechanism along the dough conveying direction.
[0038] Simultaneously refer to Figure 2 The first side roller structure 3 includes a first pressure roller 31, a first lifting assembly 32 and a first mounting shaft 33. The first lifting assembly 32 is mounted on the side wall of the first frame 11. The first mounting shaft 33 is used to connect the first pressure roller 31 and the first lifting assembly 32, and the first pressure roller 31 is rotatably connected to the first mounting shaft 33.
[0039] The first lifting assembly 32 includes a lifting plate 321 and a first bolt 322. A first mounting shaft 33 is mounted on the lifting plate 321. The lifting plate 321 can be a metal plate with certain strength and rigidity, or it can be a plastic plate, which is lightweight and low-cost. In this embodiment, it is made of metal. The lifting plate 321 has an oblong hole 323. The first bolt 322 passes through the oblong hole 323 and is threaded to the side wall of the first frame 11, so that the lifting plate 321 is clamped between the head of the first bolt 322 and the first frame 11.
[0040] By adjusting the position of the first bolt 322 in the oblong hole 323, the height of the lifting plate 321 can be changed, the contact pressure between the first pressure roller 31 and the final roll of the dough can be changed, and the thickness of the final roll of the dough can be changed. At the same time, the lifting plate 321 can rotate on the side wall of the first frame 11, thereby changing the position of the first pressure roller 31 and the distance between the first pressure roller 31 and the conveying assembly, and improving the practicality of the first lifting assembly 32.
[0041] The lifting plate 321 has a movable hole 324 through which the first mounting shaft 33 passes. The lifting plate 321 is equipped with a fastener 34 for fixing the first mounting shaft 33 to the lifting plate 321. In this embodiment, the fastener 34 is a second bolt. The lifting plate 321 has a threaded hole communicating with the movable hole 324. The second bolt is threaded into the threaded hole to abut against the outer wall of the first mounting shaft 33. Tightening the second bolt to ensure tight contact with the outer wall of the first mounting shaft 33 fixes the position of the first mounting shaft 33.
[0042] By adjusting the contact position between the first mounting shaft 33 and the fastener 34, the contact area between the first pressure roller 31 and the dough can be changed, or the position of the first pressure roller 31 can be adjusted according to the width of the dough, thereby further reducing the problem of poor adhesion after the dough is rolled up.
[0043] The first pressure roller 31 is made of stainless steel, which can improve the service life of the first pressure roller 31; the outer wall of the first pressure roller 31 is provided with a rubber sleeve 35, which can increase the friction with the dough and apply pressure more effectively.
[0044] Reference Figure 1 The first winding structure includes a mounting frame 41, a first winding roller 42, and a first motor 43. The mounting frame 41 is mounted on the first frame 11, and the first winding roller 42 is rotatably mounted on the mounting frame 41. The first motor 43 is used to drive the first winding roller 42 to rotate. One end of the first winding roller 42 extends toward the conveying direction of the first conveying structure 2 and is inclined toward the side of the final winding portion of the face sheet so as to be able to perform winding operations on the face sheet. Since the first winding roller 42 has the same structure as the first pressure roller 31, it will not be described in detail here.
[0045] The second rolling mechanism 5 includes a second frame 51, a second conveying structure 6 mounted on the second frame 51, a second side roller structure 7, a third side roller structure 8, and a second edge-rolling structure 9. The second conveying structure 6 is used to convey the dough and transfer it above the first conveying structure 2. The second conveying structure 6 and the first conveying structure 2 are both existing technologies. The second edge-rolling structure 9 is the same as the first edge-rolling structure 4, so it will not be described in detail here.
[0046] Simultaneously refer to Figure 3 The second side roller structure 7 is used to apply pressure to the final roll portion of the dough. The second side roller structure 7 includes a second pressure roller 71, a second lifting assembly 72, and a second mounting shaft 73. The second side roller structure 7 is the same as the first side roller structure 3, so it will not be described in detail here. It should be noted that the second pressure roller 71 is conical in shape, which can make the thickness of the dough gradually decrease from the middle to the end in the width direction.
[0047] The third side roller structure 8 is used to apply pressure to the initial rolling portion of the dough, and the second side roller structure 7 and the third side roller structure 8 are respectively arranged on opposite sides of the frame; the third side roller structure 8 includes a third pressure roller 81, a third lifting assembly 82 and a third mounting shaft 83. The third side roller structure 8 is the same as the second side roller structure 7, so it will not be described in detail here; it should be noted that the outer diameter of the third pressure roller 81 is smaller than the outer diameter of the second pressure roller 71, so that the thickness of the pre-rolled portion of the dough is greater than the thickness of the final rolled portion of the dough.
[0048] Reference Figure 1 In this embodiment, a filling structure is provided between the third side roller structure 8 and the second rolling mechanism 5. The filling structure includes a filling machine 53, a scraper 56 and a fourth lifting assembly 54. The filling machine has a filling tube 55, which is used to inject filling into the dough to further enrich the bread's texture.
[0049] Two sets of the fourth lifting assembly 54 are provided and are respectively located on both sides of the second frame 51. The structure of the fourth lifting assembly 54 is the same as that of the first lifting assembly 32, so it will not be described in detail here. The two ends of the scraper 56 are respectively connected to the two sets of the fourth lifting assembly 54. The scraper 56 is used to spread the filling evenly on the dough. The scraper 56 can adjust the distance between itself and the second conveying structure 6 through the fourth lifting assembly 54, thereby changing the filling thickness.
[0050] The implementation principle of Embodiment 1 of this application is as follows:
[0051] Both the first pressure roller 31 and the second pressure roller 71 can uniformly thin the dough on one side, thus optimizing its extensibility and flexibility. When rolled, the thinner dough is easier to fit tightly together, reducing the amount of air entering the gap between the layers and avoiding wrinkles or bulges caused by residual air. This reduces the possibility of dough delamination during baking. It also makes the final rolled part of the dough transition from a raised area to a smooth one, reducing the thickness difference and lowering the possibility of the final rolled part of the dough lifting.
[0052] Example 2:
[0053] This application discloses a double-layer leather composite molding device.
[0054] Reference Figure 4 The difference between Embodiment 2 and Embodiment 1 is that the fastener 34 includes a spring 342 and a plug rod 341. The outer wall of the lifting plate 321 is provided with a sliding groove 325 that communicates with the movable hole 324. The plug rod 341 is slidably installed in the sliding groove 325. The outer wall of the first mounting shaft 33 is provided with a plurality of plug slots 331 for the plug rod 341 to be inserted. The plug rod 341 can adjust the pressing area of the first pressure roller 31 on the surface by interlocking with different plug slots 331.
[0055] An anti-detachment plate 343 is provided at the end of the plug rod 341 away from the plug groove 331. A spring 342 is sleeved on the outer wall of the plug rod 341, and the two ends of the spring 342 are respectively connected to the anti-detachment plate 343 and the outer wall of the lifting plate 321. The elastic force of the spring 342 is used to drive the plug rod 341 to be inserted into the plug groove 331 under normal conditions, thereby increasing or decreasing the stability of the connection between the first mounting shaft 33 and the lifting plate 321.
[0056] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. 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.
