Description

Technical Field

[0001] This invention belongs to the field of pasta processing technology, specifically relating to an improved noodle pressing device for noodle production. Background Technology

[0002] Noodle sheet press: By generating extrusion and friction through the relative rotation of pairs of pressing rollers, loose dough is gradually rolled into a sheet of uniform thickness, and then the sheet is processed into noodles of different shapes by a cutting roller.

[0003] In practice, the following are the main factors that cause radial runout of the pressing roller:

[0004] 1. External load fluctuations: Inconsistent dough hardness and inconsistent feed rates cause instantaneous fluctuations in the radial load on the pressing rollers, manifesting as dynamic jumping and causing elastic deformation of the rollers. At the same time, the vibration of the equipment foundation is transmitted, causing external vibration to interfere with the stable operation of the rollers, resulting in an increase in radial displacement deviation. Especially when the natural frequency is close to the resonant frequency, the radial jump increases sharply, falling into a vicious cycle of "jumping-wearing-more severe jumping" and shortening the service life of the pressing rollers.

[0005] 2. Assembly eccentricity between the rollers and the shaft: Eccentricity between the rollers and the shaft causes the radial distance between various points on the surface to change periodically with the angle during rotation, directly causing jumps, which in turn causes a sudden increase in local pressure, and the dough is forcibly stretched; and when the rollers move away, the pressure decreases suddenly, and the dough shrinks due to elastic rebound, resulting in an uneven surface of the dough sheet with wavy lines or wrinkles.

[0006] 3. Shaft system wear: Due to insufficient material strength, long-term exposure to alternating loads (impact caused by uneven dough consistency) or uneven force during installation, the dough roller and bearing gradually bend, causing an eccentricity between the geometric center and the rotation center. During each rotation, the radial direction between the contact surface of the dough roller and the bearing exhibits a sinusoidal curve fluctuation, affecting the overall uniformity of the pressed dough.

[0036] A multi-angle progressive correction method for radial runout of the pressure rollers in a noodle pressing machine is implemented using an improved pressing device for noodle production, as described above. The specific steps are as follows:

[0037] S1: First, the trim panels move in opposite directions or back to back, and the end plates are controlled to drive the toothed plates to move in opposite directions or back to back, dynamically adjusting the total working area of ​​the toothed plates. At the same time, the toothed plates are distributed in an alternating manner, which complement each other to cover the difference in working surface between them. While strengthening the relative shearing force between the noodles, the cleaning effect of the toothed plates on the end face of the main pressure roller is improved.

[0038] During this process, through the interactive extrusion between the corner post and the wedge plate, the relative vertical distance between the toothed plate and the outer wall of the main pressure roller at different positions is equally coordinated, compensating for the phase difference between the high toothed plate and the low toothed plate, ensuring that the relative distance between the toothed plate and the outer wall of the main pressure roller at different positions is always a predetermined constant value. At the same time, through the relative movement between the corner post and the wedge plate, the relative force between the toothed plate and the end face of the main pressure roller at different positions is synchronously gradient adjusted.

[0039] S2: Next, the eccentric wheel eccentrically presses the platform, causing the platform to move a specified distance towards the toothed plate under the guidance of the corner plate and the dragging spring support, until the ball bearings come into contact with the outer wall of the main pressing roller (initially, the toothed plate contacts the main pressing roller first). After that, the radial runout between the ball bearings and the main pressing roller at different working points is collected at multiple points through the ball bearings at different positions in segments. The contact state between the adjacent electrode plates and the electrode post is used to help judge the authenticity of the contact between the relatively middle electrode plate and the electrode post, reduce runout error (dough spots may exist on the local end face of the main pressing roller), and improve the sensing accuracy.

[0040] During this process, the corner bracket is controlled by the bearing seat to drive the corner chamber to rotate, and the maximum rotation angle is 180 degrees. At the same time, the corner plate can be driven to reciprocate through the tooling frame, thus forming a two-axis linkage motion, improving the full range of coverage contact between the ball and the main pressure roller at different points, accurately sensing the maximum tilt angle of the radial runout of the main pressure roller, and improving the correction efficiency of the correction unit.

[0041] S3: Finally, during the intermittent rotation of the corner plate, the differential interaction between the end face columns causes the entire sleeve to move towards the axis of the corner steel ring under the combined support and guidance of the angle steel ring and the flange, until the rubber pad contacts the outer wall of the coupling. At the same time, when the air plug (not shown in the figure, please refer to the appearance of the clamping spring plate) elastically installed inside the air groove contacts and squeezes the coupling, the air plug introduces air into the end ring through the corner tube. In specific implementation, the corner tube and the end tube can be connected by an external hose (and the outer wall of the external hose has a one-way valve) until the clamping spring plate is at different angles to provide auxiliary clamping and limiting of the coupling, further reducing the occurrence of radial runout.

[0042] The present invention has the following beneficial effects:

[0043] 1. This invention, through the misalignment movement between the end ring and the angle steel ring, causes the corner arc plate to generate different degrees of mutual restraint between the end face column at different angles. At the same time, the connecting plate coordinates the synchronicity of movement between the angle steel ring and the corner rod, dynamically detects the maximum radial runout angle in real time from multiple angles, and always ensures the positive relativity between the cross ring axis and the radial runout "axis". It eliminates the maximum radial runout error in a directional manner, dynamically balances the radial couple, and clamps the direction of the maximum radial runout error through the positively distributed cross rings. That is, by replacing the omnidirectional suppression error with the peak value of the directional constraint error, the runout error of the non-uniform part can be transformed into a controllable static constraint, preventing the error from spreading to other directions during rotation, limiting the minimum range of overall runout, ensuring clamping stability, reducing the impact on the smoothness of the coupling rotation, and achieving dual optimization of pressing surface accuracy and equipment life.

[0044] 2. This invention dynamically compensates for the vertical distance between the high and low toothed plates and the main pressure roller by adjusting the angle of the wedge plates at different positions in a differential and equal manner. At the same time, the total coverage of the toothed plates is dynamically gradientd by the toothed plates in opposite or opposite states, which improves the shearing force and enhances the cleaning effect, reducing cleaning dead corners and omissions. Furthermore, through the interaction between the corner post and the wedge plate, the interaction force between the toothed plates and the main pressure roller is adjusted simultaneously when adjusting the distance between the relative toothed plates, cleaning the "spots" on the surface in a layered manner, avoiding excessive rigid contact between the toothed plates and the main pressure roller, protecting the integrity of the surface structure of the main pressure roller. At the same time, the return spring provides relatively "flexible" support to the toothed plates, further buffering the radial runout wear between the end face of the main pressure roller and the bearing working surface.

[0080] Simplified process of dough pressing and shaping:

[0081] The main pressing roller 16 and the auxiliary pressing roller 17 move in opposite directions. In specific implementation, an external motor can drive a set of gears 24 that cooperate with each other (which can be set outside the side compartment 11 and equipped with a corresponding protective shell) to drive the main pressing roller 16 and the auxiliary pressing roller 17 to rotate synchronously. Then, the dough is continuously carried into the gap between the main pressing roller 16 and the auxiliary pressing roller 17 under the action of the roller friction force, and undergoes rolling, stretching and forming into sheets. The dough is continuously received and transported by the conveyor belt 15.

[0082] Side compartment 11 and end compartment 12: provide blocking protection to dough extrusion unit 2 and correction unit 3 respectively, reduce interference from external environmental factors, and improve the cleanliness of the dough during forming to a certain extent.

[0083] End support 13 and conveyor support 14: respectively provide stable rigid support to end machine compartment 12, side machine compartment 11 and conveyor belt 15, rationalize the connection between noodle pressing machine units, reduce the transmission of equipment foundation vibration, improve the operation stability of noodle extrusion unit 2 and correction unit 3, and reduce the impact of external vibration on the radial runout between the main pressing roller 16 or the auxiliary pressing roller 17 and the bearing at the corresponding position.

[0084] Note: In the specific implementation process, the exfoliation unit 2 and correction unit 3 set on one side of the main pressing roller 16 can be used as a reference. Similarly, the corresponding exfoliation unit 2 and correction unit 3 can be arranged on one side of the auxiliary pressing roller 17 (with reasonable space). This embodiment only uses the main pressing roller 16 as an example for illustration.

[0085] The interaction process between the toothed plate 29 and the end face of the main pressure roller 16:

[0086] First, under the control of the column 23, the gear 24 meshes synchronously with the rack 25 (two). In specific implementation, an external motor can be connected to the gear assembly (it should be understood that the above scheme is only one feasible embodiment) to drive the column 23 to rotate a specified angle. After that, under the synchronous control of the rack 25 and the support and guidance of the return frame 22, the decorative panel 26 drives the end plate 28 to move towards or away from each other. (In specific implementation, the axial direction (refer to the movable telescopic rod 27) degree of freedom between the decorative panel 26 and the end plate 28 is released by the movable telescopic rod 27. At the same time, the relative position of the corner column 214 and the wedge plate 216 is engaged to prevent the end plate 28 from retracting under the guidance of the movable telescopic rod 27 when the toothed plate 29 is in contact with the main pressure roller 16, which would affect the gradient adjustment of the interaction force between the toothed plate 29 and the main pressure roller 16.)

[0087] Next, under the synchronous action of the end plate 28, the corner post 214 performs different degrees of compression and limiting between the wedge plate 216 at different positions. In specific implementation, the angle of the inclined surface of the wedge plate 216 at different positions in the initial state can be adjusted differentially (the space gap between the corner post 214 and the wedge plate 216 is compensated by the wall plate 215, while ensuring the interactive stability between the wedge plate 216 and the corner post 214), thereby compensating for the initial vertical distance between the high-position (larger coaxial deviation) toothed plate 29 and the low-position toothed plate 29 and the main pressure roller 16 (i.e., the initial vertical distance between the toothed plate 29 and the end face of the main pressure roller 16).

[0088] Finally, through the continuous squeezing interaction between the corner post 214 and the wedge plate 216, while changing the coverage between the relative toothed plates 29, the relative interaction degree between the toothed plates 29 and the main pressure roller 16 is simultaneously changed by gradient (the toothed plates 29 are provided with a reverse driving force by the return spring 213 to ensure the layered relative movement between the toothed plates 29 and the main pressure roller 16, while the return spring 213, end plate 28 and toothed plates 29 are protected by the gasket 212).

[0089] It should be noted that: the tooth spacing of the toothed plate 29 is equal, and during the extreme meshing process of the rack 25 and the gear 24, the teeth of the toothed plate 29 go through complete separation, partial coverage, complete coverage and partial separation, and there is a vertical height between the toothed plates 29. The toothed plates 29 at different positions can further refine the "tooth spacing", improve the shearing force, and complementarily clean the noodle "spots" on the end face of the main pressing roller 16.

[0090] The contact process between the ball bearing 231 and the main pressure roller 16 in the middle area of ​​the angle chamber 241 (deflection sensitive area, resonance sensitive area, and cumulative error concentration area):

[0091] First, through the synchronous movement between the eccentric wheel 221 and the column 23, an eccentric compression is generated between the eccentric wheel and the table 222 during rotation, until the table 222, under the support and guidance of the corner plate 21, drives the adapter 226 to move towards the toothed plate 29, until the ball 231 contacts the main pressing roller 16 (initially, the distance between the main pressing roller 16 and the toothed plate 29 is greater than the distance between the ball 231 and the main pressing roller 16. The purpose is to avoid the ball 231 from "mistakenly touching" the noodle "spots". At the same time, through the limit meshing design between the gear 24 and the rack 25, the eccentric wheel 221 rotates at a suitable angle when it is in the limit meshing, thereby achieving the contact between the ball 231 and the main pressing roller 16 (at this time, the toothed plate 29 has completed the cleaning operation of the noodle "spots" in the current area, and the contact between the ball 231 and the main pressing roller 16 depends entirely on the radial runout of the main pressing roller 16)).

[0092] Next, as the balls 231 at different points "jump" into contact with the main pressing roller 16 at different positions (changing the contact form between the balls 231 and the main pressing roller 16 to improve the smoothness and integrity of the end face of the main pressing roller 16), the telescopic spring rod 228, under the control of the reverse force of the water distribution plate (the support plate 227 provides stable support and guidance to the telescopic spring rod 228 to ensure the jumping contact accuracy between the balls 231 and the main pressing roller 16), drives the electrode plate 232 to move towards the T-plate 233 until the electrode plate 232 contacts the electrode post 235;

[0093] Finally, by making contact between the electrode plate 232 and the electrode post 235 at multiple points (in specific implementation, the electrode post 235 and the external power supply equipment are provided with electrical connection conditions through the corner connector 236), the accidental contact between the ball 231 and the noodle "spots" (there may be noodle "spots" remaining in some areas) is further avoided, and the jumping contact monitoring accuracy between the ball 231 and the main pressing roller 16 is improved.

[0094] The process of ball bearing 231 contacting the main pressure roller 16 at multiple circumferential angles:

[0095] Under the guidance of the crescent ring 245, the bearing seat 243 synchronously controls the angle bracket 242 and the angle clamping chamber 241 to move at a specified angle (since the opening of the crescent ring 245 is greater than half a circle, and more than half of the main pressing roller 16 is inside the end position chamber 12, the rotation range of the bearing seat 243 is 0-180. At this time, the correction unit 3 of the positive orientation distribution state has completely covered the full-angle orientation clamping and positioning conditions).

[0096] During this process, under the synchronous action of the bearing seat 243, the angle bar 244 and the angle ring 246 can drive the correction unit 3 to implement directional runout constraint on the coupling 18 at the same angle when the ball bearing 231 detects the maximum runout angle of the main pressure roller 16.

[0097] Reference Figure 3 , Figure 11 and Figure 12 It can be seen that the correction unit 3 includes: an end ring 31, which is rotatably mounted on the inner wall of the side chamber 11 and is coaxially arranged with the main pressing roller 16; an angle arc plate 32, which is installed in groups of four and is circumferentially and evenly snapped onto the inner wall of the end ring 31 near the angle chamber 241; an angle steel ring 33, which is rotatably mounted on the end face of the end ring 31 near the angle chamber 241; in addition, the angle steel ring 33 is rotatably mounted with the inner wall of the side chamber 11; and a connecting plate 34, which is snapped onto the angle ring 246 and the angle steel ring 33. The mouthpiece frame 35 is symmetrically snapped onto the inner wall of the angle steel ring 33; furthermore, the mouthpiece frame 35 and the connecting plate 34 are directly opposite each other; the tube 36 is slidably snapped onto the mouthpiece frame 35 and the angle steel ring 33; the telescopic spring 37 is sleeved onto the outer wall of the tube 36, and the telescopic spring 37 is located between the mouthpiece frame 35 and the angle steel ring 33; the end face column 38 is snapped onto the outer wall of the end of the tube 36 away from the mouthpiece frame 35; the micro motor 39 is embedded and snapped onto the inner wall of the end of the tube 36 away from the mouthpiece frame 35.

[0098] Reference Figure 11 , Figure 12 and Figure 13 It can be seen that the output end of the micro motor 39 is fitted with a shaft base 312, and the outer wall of the shaft base 312 is threaded with a face ring 311 that is slidably fitted with the inner wall of the tube 36. The inner wall of the tube 36 near the micro motor 39 is symmetrically fitted with a positioning ring 313, and the shaft base 312 away from the micro motor 39 is slidably fitted with a spring plug 314 that is slidably fitted with the positioning ring 313 at the shaft center. The spring plug 314 has an external spring located between the positioning ring 313 and the face ring 311. Between 11, a ring 315 is snapped onto the outer wall of the spring plug 314 away from the micro motor 39. A guide rod 316 is slidably snapped onto the end face of the dividing ring 313 near the micro motor 39 with a ring 311 on the same side. An angle valve 317 is symmetrically inserted into the outer wall of the tube 36. A piston 318 is slidably snapped onto the inner wall of the tube 36 away from the micro motor 39. A cross ring 319 is snapped onto the end of the piston 318 away from the micro motor 39.

[0099] Reference Figure 11 , Figure 12 and Figure 13It can be seen that the piston 318 is symmetrically inserted with a corner tube 321 on the outer wall near the end of the coupling 319. An air groove 322 is opened between the corner tube 321, the piston 318 and the coupling 319. A rubber gasket 323 is snapped onto the inner wall of the end of the coupling 319 away from the piston 318. An end tube 324 is symmetrically inserted into the outer wall of the coupling 319. A clamping spring plate 325 is slidably snapped onto the inner wall of the end tube 324. The inner diameter of the clamping spring plate 325 is equal to the outer diameter of the coupling 319 and the coupling 18.

[0100] The positive clamping process of the interlocking ring 319 against the outer wall of the coupling 18 at the maximum runout angle:

[0101] First, under the synchronous action of the connecting plate 34, the angle steel ring 33 drives the sleeve to rotate until the interlocking ring 319 is at the peak of the runout error (in specific implementation, the end ring 31 can be rotated by an external motor to a specified angle to ensure the degree of compression interaction between the angle arc plate 32 and the end face column 38). After that, under the joint support and guidance of the angle steel ring 33 and the gusset frame 35, the sleeve stably controls the movement of the interlocking ring 319 towards the axis of the coupling 18 (the telescopic spring 37 provides a segmented multi-buffer degradation environment to the interlocking ring 319, while reducing the radial runout of the sleeve itself).

[0102] Next, when the rubber pad 323 contacts the coupling 18 (the rubber pad 323 increases friction and protects the interlocking ring 319 and the coupling 18), the air plug (not shown in the figure, but can be referred to the appearance of the clamping spring plate 325) which is elastically set inside the air groove 322, in specific implementation, the air plug contacts the coupling 18 first and is squeezed into the air plug to complete the stamping process. When the air plug contacts and squeezes the coupling 18, the air plug introduces air into the end ring 31 through the angle tube 321. In specific implementation, the angle tube 321 and the end tube 324 can be connected by an external hose (and the outer wall of the external hose has a one-way valve, and external air can enter the hose through the one-way valve) until the clamping spring plate 325 is clamped at different angles to provide auxiliary clamping and limiting of the coupling 18.

[0103] Finally, the micro motor 39 can drive the shaft 312 to rotate by a specified angle. At this time, the face ring 311 is guided by the guide rod 316 and the sleeve and moves continuously towards the dividing ring 313. This changes the compression of the "spring" outside the spring plug 314, thereby gradually adjusting the initial interaction between the spring plug 314 and the dividing ring 313 at the end away from the micro motor 39. That is, it gradually changes the "difficulty" of the piston 318 moving towards the micro motor 39, increasing the range of relative interaction between the coupling ring 319 and the coupling 18 (under long-term action, the elastic variable of the telescopic spring 37 gradually fails). In specific implementation, gas can be filled and released between the piston 318 and the dividing ring 313 through the two angle valves 317 at the outer end to ensure that the gas equivalent between the two is stable. Only the interval between the spring plug 314 and the dividing ring 313 is changed, and the reverse force between the piston 318 and the spring plug 314 is gradually changed.

[0104] The present invention provides an improved pressing device for noodle production. The working principle is as follows: First step: The decorative panel 26 moves in opposite directions or back to back, and the end plate 28 is synchronously controlled to drive the toothed plate 29 to move in opposite directions or back to back, dynamically adjusting the total working area of ​​the toothed plate 29. At the same time, the toothed plates 29 are distributed in an alternating manner, which complement each other to cover the difference in working area between them, strengthen the relative shear force between the noodles, and improve the cleaning effect of the toothed plate 29 on the end face of the main pressing roller 16.

[0105] During this process, through the interactive extrusion between the corner post 214 and the wedge plate 216, the relative vertical distance between the toothed plate 29 and the outer wall of the main pressure roller 16 at different positions is equally coordinated, compensating for the phase difference between the high toothed plate 29 and the low toothed plate 29, ensuring that the relative distance between the toothed plate 29 and the outer wall of the main pressure roller 16 at different positions is always a predetermined constant value. At the same time, through the relative movement between the corner post 214 and the wedge plate 216, the relative force between the toothed plate 29 and the end face of the main pressure roller 16 at different positions is synchronously and gradient adjusted.

[0106] The second step involves eccentrically pressing the platform 222 with the eccentric wheel 221. Under the support and guidance of the corner plate 21, the platform 222 controls the ear plate 223 to drag the spring support 225 and move a specified distance towards the toothed plate 29 until the ball bearing 231 contacts the outer wall of the main pressing roller 16 (initially, the toothed plate 29 contacts the main pressing roller 16 first). After that, the radial runout between the ball bearing 231 and different working points of the main pressing roller 16 is collected at multiple points through the ball bearing 231 at different positions in segments. The contact state between the adjacent electrode plate 232 and the electrode post 235 is used to help judge the authenticity of the contact between the relatively middle electrode plate 232 and the electrode post 235, reduce the runout error (dough spots may exist on the local end face of the main pressing roller 16), and improve the sensing accuracy.

[0107] During this process, the corner bracket 242 is controlled by the bearing seat 243 to drive the corner chamber 241 to rotate, and the maximum rotation angle is 180 degrees. At the same time, the corner plate 21 can be driven to reciprocate through the tooling frame 1, thereby forming a two-axis linkage motion, improving the full range of coverage contact between the ball 231 and the main pressure roller 16 at different points, accurately sensing the maximum tilt angle of the radial runout of the main pressure roller 16, and improving the correction efficiency of the correction unit 3.

[0108] Step 3: Finally, as the corner plate 32 rotates intermittently, the differential interaction between the end face columns 38 causes the entire sleeve to move towards the axis of the corner plate 33 under the combined support and guidance of the angle steel ring 33 and the flange 35, until the rubber pad 323 contacts the outer wall of the coupling 18. At the same time, when the air plug (not shown in the figure, but can be referred to the appearance of the clamping spring plate 325) elastically set inside the air groove 322 contacts and squeezes the coupling 18, the air plug introduces air into the end ring 31 through the corner tube 321. In specific implementation, the corner tube 321 and the end tube 324 can be connected by an external hose (and the outer wall of the external hose has a one-way valve) until the clamping spring plate 325 is clamped at different angles to provide auxiliary clamping and limiting of the coupling 18, further reducing the occurrence of radial runout.
