Detailed implementation method
[0025] Next, in combination with Figures 1 - 8 a specific embodiment of the present invention will be elaborated in detail.
[0026] Refer to Figures 1 - 8 , a noodle forming auxiliary device for handmade noodle making, including a support frame 1, a motor 11 is installed on the support frame 1, a noodle pressing turntable 12 is rotatably connected to the support frame 1, the dough is placed on the noodle pressing turntable 12, the noodle pressing turntable 12 is connected to the output shaft of the motor 11, a noodle pressing roller 16 is rotatably connected to the noodle pressing turntable 12, the noodle pressing roller 16 presses and levels the dough, a flour box 36 is provided on the noodle pressing roller 16, flour is pre-added to the flour box 36, and the flour is scattered on the noodle pressing roller 16 to increase the lubricity between the noodle pressing roller 16 and the dough and prevent the dough from sticking.
[0027] Refer toFigure 2 The output shaft of the motor 11 penetrates through the surface pressing turntable 12 and is connected to the first bevel gear 15. A bracket 17 is fixedly connected to the support frame 1. A rotating rod 13 is rotatably connected to the bracket 17. One end of the rotating rod 13 is fixedly connected to the second bevel gear 151. The first bevel gear 15 contacts the second bevel gear 151. A surface pressing roller 16 for pressing the dough is fixedly connected to the rotating rod 13, aiming to drive the surface pressing roller 16 through the meshing transmission of the first bevel gear 15 and the second bevel gear 151.
[0028] The dough to be formed is placed on the surface pressing turntable 12. The motor 11 triggers the rotation of the surface pressing turntable 12 and the first bevel gear 15, driving the dough to rotate. Based on the action of the first bevel gear 15 and the second bevel gear 151, the rotating rod 13 and the surface pressing roller 16 are controlled to rotate, that is: the surface pressing roller 16 rotates self, realizing the surface pressing action.
[0029] According to the background technology, the dough is easy to stick after being extruded by the surface pressing roller 16. Therefore, this device solves this problem through an automatic powder spraying assembly: A support column 14 is rotatably connected to the center of the surface pressing turntable 12. The support column 14 is a hollow column body. One is to protect the first bevel gear 15 and the second bevel gear 151 inside, and the other is to provide support for the automatic powder spraying assembly. Specifically: A connecting rod 3 is fixedly connected to the top of the support column 14. A sliding rod 31 is slidably connected to the connecting rod 3. A shaking part 35 is fixedly connected to the sliding rod 31. The telescopic end of a telescopic part 33 is connected to the shaking part 35. The telescopic part 33 is fixedly connected to the bracket 17. An extrusion spring is provided between the shaking part 35 and the fixed end of the telescopic part 33. A flour box 36 is also provided on the shaking part 35. The shaking part 35 and the flour box 36 are stabilized on the top of the surface pressing roller 16 through the support column 14, the connecting rod 3, the sliding rod 31, the telescopic part 33 and the bracket 17.
[0030] To facilitate the powder output of the flour box 36, a plurality of micro holes are opened on the shaking part 35, and the bottom of the flour box 36 has no sealing plate, that is: the flour in the flour box 36 is scattered on the surface pressing roller 16 through the micro holes on the shaking part 35.
[0031] In the normal state, the flour is not easy to fall from the micro holes on the shaking part 35. To ensure the smooth falling of the flour, the following settings are made: A clamping part 32 is key-connected to the sliding rod 31. An arc-shaped chute 34 is opened on the rotating rod 13. The bottom of the clamping part 32 is fitted in the chute 34, aiming to realize the sliding action of the sliding rod 31 through the clamping part 32 and the chute 34, and then make the shaking part 35 act, facilitating the powder output.
[0032] Based on the action of the motor 11, the dough pressing turntable 12 and the first bevel gear 15 rotate, the first bevel gear 15 is meshed with the second bevel gear 151, the rotating rod 13 and the dough pressing roller 16 rotate under control, the dough pressing roller 16 squeezes the dough, and the clamping member 32 slides along the slide groove 34. Based on the arc design of the slide groove 34, the clamping member 32 slides left and right, the linkage sliding rod 31 slides left and right, the telescopic part of the telescopic member 33 extends or contracts, and the shaking member 35 and the flour box 36 shake left and right, so that the flour falls onto the dough pressing roller 16, reduces the adhesion between the dough and the dough pressing roller 16, and avoids excessive stickiness of the dough and causing waste of raw materials.
[0033] During the dough pressing process, flour is scattered on the surface of the dough pressing roller 16 and is integrated into the dough. There is a situation where the dough is too dry due to excessive flour, and the hardness is high and the elasticity is reduced, which is difficult to shape and shape, and the taste is affected. Therefore, the device uses a water replenishing component to adjust the moisture content of the dough and restore the ductility of the dough. Figure 3 , Figure 4 Specifically, a fixing plate 44 is fixedly connected between the connecting rod 3 and the bracket 17, a connecting block 441 is slidably connected to the fixing plate 44, a water storage member 410 is connected between the connecting block 441 and the fixing plate 44, a hollow pipe for storing water is provided on the water storage member 410, a water outlet 442 is provided at the bottom of the pipe for facilitating water discharge, and one end of the water storage member 410 is connected to an external water source through a pipe,
[0034] A sliding column 45 is slidably connected through the fixing plate 44, and a fixing member 41 is slidably connected to the bottom of the sliding column 45. A water outlet member 4 is sleeved on the water storage member 410, and a through groove 43 that can be adapted to the water outlet groove 442 is opened on the water outlet member 4. The water outlet groove 442 and the through groove 43 correspond to achieve the water outlet effect. If the water outlet groove 442 and the through groove 43 are misaligned, the water outlet is blocked. A torsion spring 42 is compressed between the water outlet member 4 and the fixing member 41 and the connecting block 441, in order to maintain the misalignment effect of the water outlet groove 442 and the through groove 43 through the torsion spring 42.
[0035] The dough pressed by the dough pressing roller 16 rotates with the dough pressing turntable 12 and moves to the bottom of the water outlet member 4. There is friction between the dough coated with flour and the water outlet member 4. As the dough rotates, the water outlet member 4 is driven to rotate, the torsion spring 42 is deformed, the through groove 43 and the water outlet groove 442 correspond, and water flows out from the through groove 43 and soaks the surface of the dough. The friction between the dough coated with water and the water outlet member 4 is reduced. Under the action of the two torsion springs 42, the water outlet member 4 rotates in the opposite direction to reset, and the through groove 43 and the water outlet groove 442 are misaligned again to block the water outlet, so as to prevent the dough from being overly coated with water and difficult to shape.
[0036] The purpose of the automatic powder spraying component and the water replenishing component of the device is to adjust the state of the dough so that it can be evenly formed under the pressing action of the dough pressing roller 16 and ensure the taste. The automatic powder spraying component and the water replenishing component need to be flexibly switched according to the real-time state of the dough, that is: one of the automatic powder spraying component and the water replenishing component is turned on. When the dough is too soft, the water replenishing component is turned off and the automatic powder spraying component is turned on. When the dough is too hard, the automatic powder spraying component is turned off and the water replenishing component is turned on. Based on this, the device is achieved through a switching component.
[0037] refer to Figure 8 The switching assembly includes a spiral member 49 fixedly connected to the water outlet member 4, wherein the spiral member 49 is partially protruding and rotatably built into the fixing member 41. A connecting plate 46 is connected to the clamping member 32, and the purpose is to cancel the key connection between the clamping member 32 and the sliding rod 31 by moving the connecting plate 46, so that the clamping member 32 cannot transmit the sliding rod 31, and therefore, the shaking member 35 is stationary.
[0038] In order to realize the movement of the connecting plate 46, the sliding column 45 passes through the fixing part 41 and contacts the spiral part 49. It should be noted that the upper end of the sliding column 45 contacts the connecting plate 46, and the lower end of the sliding column 45 contacts the spiral part 49. The purpose is to make the sliding column 45 slide up and down and then move the connecting plate 46 up and down through the extrusion fit between the sliding column 45 and the local protrusion of the spiral part 49.
[0039] refer to Figure 7 A guide rod 47 is slidably connected through the connecting plate 46 , a limit cap is provided at the end of the guide rod 47 , and a force storage spring 48 is provided between the limit cap and the connecting plate 46 , so as to realize the resetting action of the connecting plate 46 through the force storage spring 48 .
[0040] Initially, the through groove 43 and the water outlet groove 442 are misaligned. Based on the cooperation of the slide groove 34 and the clamping member 32, the sliding rod 31 slides left and right, and the shaking member 35 and the flour box 36 shake left and right to discharge flour. The dough is not easy to stick to the dough roller 16 when it is sticky with flour. After the dough is excessively sticky with flour, the friction between the dough and the water outlet member 4 increases, driving the water outlet member 4 and the spiral member 49 to rotate, the torsion spring 42 is deformed, the through groove 43 and the water outlet groove 442 correspond, and the water flows out from the through groove 43 and soaks the surface of the dough. Based on the rotation of the spiral member 49, the local protrusion of the spiral member 49 squeezes the sliding column 45, and the sliding column 45 moves up and squeezes the connecting plate 46. The linkage connecting plate 46 moves up on the guide rod 47, and the storage spring 48 is deformed. The clamping member 32 cancels the key connection with the sliding rod 31, the sliding rod 31 is stationary, the shaking member 35 and the flour box 36 remain stationary synchronously, and the flour stops scattering.
[0041] After the dough is moistened and softened, the friction between the dough and the water outlet member 4 is reduced. Based on the force of the torsion spring 42, the water outlet member 4 and the spiral member 49 rotate in the opposite direction to reset, the through groove 43 and the water outlet groove 442 are misaligned, and the outflow of water is blocked. Based on the reverse rotation of the spiral member 49, the local protrusion of the spiral member 49 cancels the extrusion with the sliding column 45, the sliding column 45 moves down and cancels the extrusion with the connecting plate 46, the linkage connecting plate 46 moves up and down on the guide rod 47, the storage spring 48 is restored, and the clamping member 32 is connected to the sliding rod 31 again, and the clamping member 32 slides along the slide groove 34. Based on the arc design of the slide groove 34, the clamping member 32 slides left and right, the linkage sliding rod 31 slides left and right, the shaking member 35 and the flour box 36 slide left and right synchronously, the flour is scattered, and the dough surface is stained with flour and the humidity is reduced, thereby achieving the effect of flexible switching of the automatic powder spraying component and the water replenishing component according to the real-time state of the dough.
[0042] refer to Figure 1 , considering that if the dough is not pre-shaped into a uniform thickness, the dough pressing roller 16 will be subjected to uneven local force, thereby affecting the uniformity of the dough after pressing. In order to achieve the effect of uniform dough pressing, the present device is implemented through the following settings: a plurality of feeding ports 121 are provided through the dough pressing turntable 12, and the dough to be pressed is uniformly moved up to the top of the dough pressing turntable 12 through the feeding ports 121, and the dough pressing roller 16 can achieve the effect of uniform pressing. In order to facilitate the dough to be uniformly moved up from the uniform feeding ports 121 to the top of the dough pressing turntable 12, the bottom of the dough pressing turntable 12 is provided with There are storage barrels 25 corresponding in number and diameter to the feeding port 121, and the storage barrels 25 are communicated with the feeding port 121. A top plate 23 is slidably connected to the bottom of the storage barrel 25, and the dough is placed on the top plate 23, so that the dough moves up at a uniform speed with the top plate 23. An air bag 2201 is provided at the bottom of the top plate 23, and an air pump 2 is installed on the support frame 1. The air pump 2 is connected to the air bag 2201 through an air pipe 21, and the air pipe 21 is rolled on the support frame 1, so that the air bag 2201 can be expanded by starting the air pump 2, thereby driving the top plate 23 and the dough thereon to move up at a uniform speed.
[0043] Before the device is started, the dough to be pressed is placed on the top plate 23, which is located at the bottom of the storage barrel 25. The motor 11 and the air pump 2 are started, and the dough pressing turntable 12 and the storage barrel 25 rotate. Based on the existence of the air pipe 21, the air bag 2201 expands at a uniform speed, and the top plate 23 and the dough move up to the top of the dough pressing turntable 12 at a uniform speed.
[0044] In order to keep the top plate 23 stable at the bottom of the storage bucket 25 in the initial state, and at the same time prevent the top plate 23 from sliding out of the storage bucket 25 due to the addition of dough, a rotating cover 22 is rotatably connected to the support frame 1, and the contact part between the support frame 1 and the rotating cover 22 can form a connected airway, so that the air pump 2 is connected to the airway formed by the support frame 1 and the rotating cover 22 through the air pipe 21, and the gas is delivered to the air bag 2201.
[0045] A support member 24 is connected to the rotating cover 22. The support member 24 is connected to both the bottom of the airbag 2201 and the bottom of the rotating cover 22. The support member 24 provides a supporting force to the airbag 2201, and thus provides a supporting force to the top plate 23. Before the air pump 2 is started, the top plate 23 is maintained stable at the bottom of the storage barrel 25. When the noodle pressing turntable 12 rotates, the support member 24 rotates, driving the rotating cover 22 to rotate, and the top of the airbag 2201 expands uniformly. Through the acting force of the top of the airbag 2201, the top plate 23 and the dough move upward uniformly to the top of the noodle pressing turntable 12 and are uniformly formed under the action of the noodle pressing roller 16.
[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
