The folding and rolling device can fold and roll the strip of dough to achieve kneading of the strip of dough, and the dough after folding and rolling can also be a long strip connected. The stripping device is used to cut the dough after folding and rolling and proofing by the folding and rolling device into multiple strips, thereby completing the strip making process. After the strip making process, the strip of dough can be rolled into a cylindrical shape by a strip rolling device, and then stretched and aired to make hollow noodles.

[0068] Please refer to Figures 1 to 5 In this embodiment, the dough embryo folding and rolling device 100 includes a first conveyor belt 110, a second conveyor belt 130, a folding assembly 150 and a rolling assembly 170. The first conveyor belt 110 is used to transmit strip dough embryos. The strip dough embryos cut by the sheeting and cutting device will be spliced ​​along the length direction on the first conveyor belt 110 to form continuous strip dough embryos for conveying to the next process. The second conveyor belt 130 is arranged at one end of the first conveyor belt 110, and the end close to the first conveyor belt 110 is lower than the first conveyor belt 110. The folding assembly 150 is arranged between the first conveyor belt 110 and the second conveyor belt 130. The strip dough embryos transmitted by the first conveyor belt 110 can be folded along the width direction of the folding assembly 150 and then transferred to the second conveyor belt 130. The rolling assembly 170 is arranged on the second conveyor belt 130, and the rolling assembly 170 can roll the dough embryos folded along the width direction.

[0069] Please refer to Figures 1 to 5 In this embodiment, a folding assembly 150 is arranged between the first conveyor belt 110 and the second conveyor belt 130, and the folding assembly 150 is arranged between the first conveyor belt 110 and the second conveyor belt 130, so that the strip-shaped dough embryos prepared in the previous process and transmitted by the first conveyor belt 110 can be folded by the folding assembly 150, and the folded dough embryos are transmitted to the second conveyor belt 130 and then rolled by the rolling assembly 170, and the cooperation of folding and rolling can realize the kneading of the strip-shaped dough embryos. Most importantly, the dough embryos after folding and rolling are still continuous strips, and do not need to be cut, etc., which makes it easier to realize continuous assembly line production. Secondly, the first conveyor belt 110 and the second conveyor belt 130 can also be used for the proofing of the dough embryos.

[0070] In this embodiment, the folding assembly 150 includes a mounting base 151 and a plurality of guide rods 152. The plurality of guide rods 152 are mounted on the mounting base 151 and are rotatable, and are mutually surrounded to form a folding channel 153. After being guided by the plurality of guide rods 152 of the folding channel 153, the strip of noodle embryo can be folded in the width direction of the strip of noodle embryo.

[0071] In this embodiment, a plurality of guide rods 152 are arranged on the mounting frame 171, and the guide rods 152 are used to form a folding channel 153, so that when the continuous noodle strips transported by the first conveyor belt 110 pass through the folding channel 153, the plurality of guide rods 152 guide and cooperate with each other, so that the noodle strips are folded in half along the width direction. No driving device is required, and the noodle strips can be folded in half when passing through.

[0072] In this embodiment, the first conveyor belt 110 and the second conveyor belt 130 are placed vertically. The plurality of guide rods 152 include a first guide rod 154, a second guide rod 155 and a third guide rod 156. The first guide rod 154 and the second guide rod 155 are arranged at an angle and are both fixedly connected to the mounting base 151. The opening area formed by the first guide rod 154 and the second guide rod 155 faces the first conveyor belt 110. The third guide rod 156 is fixedly connected to the mounting base 151 and encloses the first guide rod 154 and the second guide rod 155 to form a folded channel 153. The projections of the first guide rod 154, the second guide rod 155 and the third guide rod 156 on the second conveyor belt 130 are triangular.

[0073] In this embodiment, the first guide rod 154, the second guide rod 155 and the third guide rod 156 are arranged in a triangular shape in space, so that when the strip noodle embryo moves down along the folding channel 153, the first guide rod 154 and the second guide rod 155 arranged at an angle will guide the two sides of the strip noodle embryo toward the middle, and fold the noodle embryo in the width direction at the intersection of the first guide rod 154 and the second guide rod 155. The third guide rod 156 is used to limit the noodle embryo so that the noodle embryo can contact the first guide rod 154 and the second guide rod 155 when passing through the folding channel 153.

[0074] It should be noted that the width of the continuous strip of dough is generally greater than the side length of the triangular folding channel 153, so that the dough will be better contacted with the first guide rod 154 and the second guide rod 155 when passing through, so that the first guide rod 154 and the second guide rod 155 can be used to guide the dough so that the dough can be folded. The first conveyor belt 110 and the second conveyor belt 130 are placed vertically so that the folded dough can be placed horizontally on the second conveyor belt 130 and transported by the second conveyor belt 130.

[0075] Please refer to Figures 1 to 5In this embodiment, the plurality of guide rods 152 further include a fourth guide rod 157 and a fifth guide rod 158. The second conveyor belt 130 is configured to transport the dough embryos from the first guide rod 154 to the second guide rod 155. In the height direction, the second guide rod 155 is located below the first guide rod 154, and the third guide rod 156 is located between the first guide rod 154 and the second guide rod 155. The fourth guide rod 157 is fixedly mounted on the mounting base 151, and is inclined toward one side of the second guide rod 155, and is located below the second guide rod 155. The angle between the projections of the first guide rod 154 and the second guide rod 155 on the second conveyor belt 130 is greater than the angle between the projections of the first guide rod 154 and the fourth guide rod 157 on the second conveyor belt 130. The fifth guide rod 158 is disposed below the fourth guide rod 157, and is perpendicular to the transmission direction of the second conveyor belt 130. The included angle of the projections of the first guide rod 154 and the fourth guide rod 157 on the second conveyor belt 130 is greater than the included angle of the projections of the first guide rod 154 and the fifth guide rod 158 on the second conveyor belt 130 .

[0076] In this embodiment, the fourth guide rod 157 is arranged below the second guide rod 155 at an interval, and the angle is smaller, so that the dough embryo folded in half by the first guide rod 154 and the second guide rod 155 can be further folded in half by the fourth guide rod 157 with a smaller angle, so that the folding angle becomes smaller. The fifth guide rod 158 is arranged parallel to the width direction of the second conveyor belt 130, so that the angle is smaller. The most important thing is to change the direction of the dough embryo so that it can be placed on the second conveyor belt 130 along the conveying direction of the second conveyor belt 130, thereby completing the folding of the dough embryo along the width direction and can be placed horizontally on the second conveyor belt 130.

[0077] Please refer to Figures 1 to 5 In this embodiment, a plurality of slide grooves 159 are provided on the mounting base 151 , and a plurality of guide rods 152 are correspondingly installed in the slide grooves 159 .

[0078] In this embodiment, the slide groove 159 is arranged on the mounting base 151, so that the installation heights of the first guide rod 154, the second guide rod 155, the third guide rod 156, the fourth guide rod 157 and the fifth guide rod 158 can be adjusted, which is more convenient for setting, debugging and installation.

[0079] It should be noted that the slide groove 159 can be arranged in the height direction, can be arranged in the horizontal direction, or can be arranged in an inclined manner. The function of the slide groove 159 is to adjust the installation position during the installation of the equipment.

[0080] It should be noted that the mounting base 151 is a metal support frame welded to the frame of the first conveyor belt 110 and the frame of the second conveyor belt 130 .

[0081] Further, the guide rod 152 includes a mounting rod 161 and a rotating drum 162 rotatably disposed on the mounting rod 161. The mounting rod 161 is connected to the mounting base 151, and the mounting rod 161 is a threaded metal rod, and the angle of the rotating drum 162 can be changed by bending.

[0082] In this embodiment, the mounting rod 161 is provided with a threaded metal rod, which can be installed in the slide groove 159 through a nut. During debugging, the screw rod 178 can be bent to achieve a desired tilt angle to achieve better installation. The mounting rod 161 is provided with a rotating drum 162, so that the rotating drum 162 can rotate when the dough embryo contacts the dough embryo and the dough embryo moves downward, thereby not affecting the outer surface of the dough embryo.

[0083] Please refer to Figures 1 to 5 In this embodiment, the rolling assembly 170 includes a mounting frame 171, a first pressure roller 172, a second pressure roller 173, an adjustment assembly 174 and a driving assembly (not shown). The mounting frame 171 is arranged on both sides of the second conveyor belt 130. The first pressure roller 172 is mounted on the mounting frame 171 and is located above the second conveyor belt 130. The second pressure roller 173 is mounted on the mounting frame 171 through the adjustment assembly 174, and the adjustment assembly 174 is configured to adjust the distance between the first pressure roller 172 and the second pressure roller 173. The driving assembly is arranged on the mounting frame 171 and is transmission-connected to the first pressure roller 172 and the second pressure roller 173, and is used to drive the first pressure roller 172 and the second pressure roller 173 to rotate. The driving assembly can be a power element such as a motor.

[0084] In this embodiment, the passage between the first pressing roller 172 and the second pressing roller 173 is provided to roll the folded dough embryo, so that the two folded parts can be formed into a whole. The use of the first pressing roller 172 and the second pressing roller 173 to roll the dough embryo can prevent the dough embryo from being adhered to the second conveyor belt 130 after rolling. The adjustment component 174 can adjust the position of the second pressing roller 173, thereby adjusting the distance between the first pressing roller 172 and the second pressing roller 173, so as to meet the selection of different required thicknesses.

[0085] Please refer to Figures 1 to 5 In this embodiment, the mounting frame 171 is provided with a guide rail groove 176. The adjustment assembly 174 includes a mounting seat 177, a screw rod 178 and a hand wheel 179. The mounting seat 177 is provided in the guide rail groove 176, and the second pressure roller 173 is rotatably mounted on the mounting seat 177. The mounting frame 171 is provided with a threaded hole 181 connected to the guide rail groove 176, one end of the screw rod 178 is rotatably connected to the mounting seat 177, and the other end passes through the threaded hole 181 and is threadedly engaged with the threaded hole 181. The hand wheel 179 is installed on the screw rod 178, and rotating the hand wheel 179 can drive the screw rod 178 to rotate so as to drive the mounting seat 177 to move along the direction of the guide rail groove 176.

[0086] In this embodiment, the hand wheel 179 and the screw rod 178 are used to drive the mounting seat 177 to move along the guide groove 176 to adjust the distance between the first pressure roller 172 and the second pressure roller 173.

[0087] In this embodiment, two guide rods are arranged on the mounting base 151 and inclined toward the first pressing roller 172. The two guide rods are arranged on both sides of the width direction of the first pressing roller 172. In this way, the folded dough will go along between the two guide rods and enter the gap between the first pressing roller 172 and the second pressing roller 173 under the guidance of the guide rods.

[0088] Furthermore, the width of the first pressing roller 172 is greater than that of the second pressing roller 173, and opposite limiting rings are provided at both ends of the rolling surface of the first pressing roller 172. The second pressing roller 173 is located between the two limiting rings, and the distance between the two annular limiting plates is slightly greater than the distance between the two ends of the second pressing roller 173, so that the first pressing roller 172 and the second pressing roller 173 can be prevented from affecting each other when they rotate relative to each other. The provision of the two annular limiting plates can prevent the squeezed dough from overflowing from the side, thereby ensuring that the dough rolled by the first pressing roller 172 and the second pressing roller 173 has the same width.

[0089] Of course, in some other embodiments of the present application, only one pressing roller may be provided on the second conveyor belt 130. The folded dough embryo will be pressed by the pressing roller when passing through the pressing roller. This structure is simple, but there is a risk that the dough embryo pressed by the pressing roller may adhere to the second conveyor belt 130.

[0090] Furthermore, the first conveyor belt 110 is provided with a heat preservation cover, which is on the outer periphery of the conveying surface of the first conveyor belt 110 to achieve heat preservation and moisture retention, so that the dough embryo can be proofed again on the first conveyor belt 110 when transporting the dough embryo.

[0091] Please refer to Figures 1 to 5 In this embodiment, the dough folding and rolling device 100 further includes a plurality of proofing conveyor belts 190. The plurality of proofing conveyor belts 190 are stacked in the height direction and are arranged on a side of the second conveyor belt 130 away from the second conveyor belt 130.

[0092] In this embodiment, a plurality of proofing conveyor belts 190 are stacked in height, which can save space and form a heat-insulating and moisture-retaining transmission channel between the stacks, which is beneficial to the proofing of the dough. Secondly, the proofing conveyor belt 190 can be used as a proofing bed for the dough and can also be used to transfer the dough to the next process.

[0093] Specifically, the stacking quantity of the proofing conveyor belt 190 can be set according to the process requirements, such as the proofing time, the speed of the production line, etc.

[0094] In this embodiment, the proofing conveyor belt 190 is arranged perpendicularly to the second conveyor belt 130. A roller 201 and a rotating rod 202 are arranged at one end of the proofing conveyor belt located at the top close to the second conveyor belt 130. The roller 201 is arranged parallel to the width direction of the proofing conveyor belt 190. The rotating rod 202 is arranged above the roller 201 and is inclined upward toward the second conveyor belt 130. After the dough embryo is guided by the rotating rod 202 and the roller 201, it can pass between the roller 201 and the top proofing conveyor belt 190. The roller 201 and the rotating rod 202 in this embodiment can conveniently guide the dough embryo.

[0095] In summary, the working principles and beneficial effects of the dough folding and rolling device 100 and the hollow noodle production line provided by the embodiment of the utility model include:

[0096] In this embodiment, a folding assembly 150 is arranged between the first conveyor belt 110 and the second conveyor belt 130, so that the strip-shaped dough embryos prepared in the previous process and transmitted by the first conveyor belt 110 can be folded by the folding assembly 150, and the folded dough embryos are transmitted to the second conveyor belt 130 and then rolled by the rolling assembly 170 to achieve kneading of the strip-shaped dough embryos. Most importantly, the dough embryos after folding and rolling are still in a continuous long strip shape, and do not need to be cut, etc., and are more likely to achieve continuous assembly line production.

[0097] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
