Description

Technical Field

[0001] This application relates to the technical field of production automation control, and particularly to a dough mixing adaptive adjustment control system. Background Art

[0002] Pasta not only includes noodles, but also buns, steamed buns, flatbreads, etc. The quality of its taste is closely related to the dough mixing process. In scenarios of large-scale pasta processing, if only manual dough mixing is relied on, on the one hand, the labor intensity is high, and on the other hand, the quality of the dough is difficult to stabilize, easily leading to uneven product quality. Therefore, dough mixing equipment is used.

[0003] Existing, a relatively expensive dough mixing equipment can mix several bags of flour at a time and can also tilt the container for dough mixing to improve the dough mixing efficiency and uniformity. However:

[0004] Many models have two speeds, high and low, for one model, such as: 110 / 220 rpm, 92.5 / 185 rpm. Customers cannot change the rotation speed during dough mixing according to the amount of flour put in and the function of the dough. To better make different types of pasta, corresponding models need to be purchased because different pastas have different requirements for gluten, etc. During use, it is also necessary to manually set the timer and operate the buttons to control the low-speed / high-speed auger, and the use experience is relatively poor. Therefore, this application proposes a new technical solution. Summary of the Invention

Detailed implementation manners

[0031] The following further elaborates on the present application in conjunction with the attached Figures 1-4 figures.

[0032] The embodiment of the present application discloses a dough kneading adaptive adjustment control system.

[0033] Referring to Figures 1-3 , the dough kneading adaptive adjustment control system includes a driven wheel 1, a frequency converter 2, a speed change assembly 3, a gravity strain mechanism 4 and a controller 5. It can be understood that this system is set based on the dough kneading equipment, and each component is correspondingly installed inside and outside the machine shell of the equipment.

[0034] Among them, the driven wheel 1 is used to drive the auger to rotate. The driven wheel 1 can be rotatably connected to the machine shell and fixedly connected to the auger on the same central axis. The driven wheel 1 is connected to the driving wheel of the output shaft of the (speed reduction) motor of the equipment through a chain, a synchronous belt or a belt, so that the motor drives the auger to rotate.

[0035] The frequency converter 2 is electrically connected to the motor corresponding to the auger. By changing the output frequency, the rotation speed of the motor can be changed, thereby changing the rotation speed of the auger.

[0036] First, it is necessary to understand why the rotation speed of the auger needs to be adjusted:

[0037] 1. If the amount of flour put into the auger corresponding to the container by the user changes significantly, for example: 1 pack, 2 packs, 3 packs, with each pack weighing more than 300g, at this time, if the same rotation speed is used, as the number of packs increases, the time for the flour to be evenly mixed with salt, sugar, etc. will change significantly. To improve efficiency, this application considers changing the rotation speed.

[0038] 2. For different types of pasta, for example: for noodles to be "chewy", the speed needs to be increased, while for those with low gluten requirements, it is not necessary.

[0039] According to the above content, it seems that equipping the motor with an inverter 2 and changing the output frequency of the inverter 2 to change the rotation speed of the motor can meet the requirements. However:

[0040] When the amount of flour changes significantly, the size of the dough changes significantly, and it is more laborious to knead the large dough, which is equivalent to an increase in the load on the motor in the equipment; at this time, if the torque of the equipment motor remains the same, it will lead to: the equipment noise increases; the vibration intensifies, that is, the original shaking becomes more severe; the equipment gets hot and is easily damaged.

[0041] Therefore, this application further includes a speed-changing component 3, which is linked to the driven wheel 1 and is used to change the transmission ratio between the driven wheel 1 and the motor corresponding to the auger, that is, to change the torque.

[0042] Correspondingly, this application also triggers the switching of the transmission ratio through a gravity strain mechanism 4 installed on the support structure of the container, that is, the gravity strain mechanism 4 is used to link the speed-changing component 3 to switch the transmission ratio under the heavy pressure of the container. For example: when the amount of flour put into the container increases, it correspondingly links the speed-changing component 3 to increase the transmission ratio.

[0043] As an automated device, the device is equipped with the above-mentioned controller 5. The controller 5 is installed in a protective box and built into the device. The controller 5 is electrically connected to the inverter 2 and a detection mechanism 6 for detecting the action information of the speed-changing component 3. The controller 5 is configured as:

[0044] S11. (Receiving the operation instruction input by the user through the operation panel) Define that the output frequency control instruction of the inverter 2 has a low-frequency instruction, a high-frequency instruction, and a single-frequency adjustment instruction for fine-tuning. That is, like the prior art, the device is still divided into two gears: low speed and high speed, but there is an additional fine-tuning;

[0045] Define the corresponding relationship between the transmission ratio and the action information of the speed-changing component 3; Example of action information: movement amount;

[0046] Define that a single-frequency adjustment instruction has multiple adjustment amounts, and each adjustment amount matches a transmission ratio.

[0047] S12. If the device is powered on (e.g., the power is turned on), request (from the user) to obtain process parameters or call the process parameters in the preset database based on the user's instructions. Before the motor operates, obtain the current transmission ratio based on the action information of the speed change component 3 this time, calculate the current auger speed according to the preset standard speed and use it for display output, and update the adjustment amount matching the single - frequency adjustment instruction according to the transmission ratio.

[0048] Control the frequency converter according to the process parameters, that is, control the output of the low - frequency instruction, high - frequency instruction, and single - frequency adjustment instruction, and record it based on the time stamp and store it in the database; among them, the process parameters include the output time of the low - frequency instruction and high - frequency instruction, as well as the output times, time, and adjustment direction (i.e., increase or decrease) of the single - frequency adjustment instruction.

[0049] According to the above settings, after this application is applied to the dough - mixing device, although the device still has two gears, first of all, as the amount of flour input by the user is different, the device can switch the transmission ratio under the action of gravity, on the one hand, change and adjust the speed, and on the other hand, change the torque, more safely and reliably meeting the dough - mixing requirements corresponding to the amount of flour.

[0050] Secondly, a fine - tuning function is provided on the basis of the two gears to have a more precise speed - regulation ability in order to cooperate with the switched transmission ratio.

[0051] Finally, the adjustment amount of a fine - tuning instruction is different each time under different transmission ratios, and will increase or decrease correspondingly, avoiding the situation where the adjusted speed is either too large or too small; even, the user can adjust the number of times the same each time according to their habits.

[0052] Under the above - mentioned control method, when the transmission ratio is switched, the motor is not rotating, that is, the driven wheel 1 is not rotating. Therefore, if an existing structure is used, such as a bicycle speed - change structure, it will easily cause the structure to be damaged, disengaged, etc. Therefore, in an embodiment of the present application, the speed - change component 3 includes a speed - change wheel 31, a special - shaped transmission belt 32, a coordination wheel 33, and a central shaft 34.

[0053] Refer to Figure 1 , where the upper end of the central shaft 34 is fixed to the housing of the device, and the lower end is suspended; the driven wheel 1 is placed flat and has a cylindrical groove at the upper part and a slot in a rectangular shape at the lower part; the cylindrical groove sleeves on the lower end of the central shaft 34, and the shaft of the auger is fixed to the housing through a bearing and has a structure that fits the slot at the upper end and is inserted into the slot; that is, the driven wheel 1 can move up and down.

[0054] There are multiple speed - change wheels 31 formed on the outer wall of the driven wheel 1. The multiple speed - change wheels 31 are distributed along the central axis direction and form a stepped structure with diameters decreasing from top to bottom. The special - shaped transmission belt 32 is in a ring shape and one end sleeves on a certain speed - change wheel 31, and the other end sleeves on the driving wheel of the output shaft of the device's motor.

[0055] It should be noted that the special-shaped transmission belt 32 should be restricted by means of upper and lower clamping plates, buckles, and an open groove on the outer belt surface to be clamped by a clamping plate, etc., and it cannot be lifted or lowered but can only rotate. That is, by lifting and lowering the driven wheel 1, the special-shaped transmission belt 32 is sleeved on the variable-speed wheels 31 with different diameters to achieve the switching of the transmission ratio.

[0056] Each variable-speed wheel 31 is closely attached to each other. The upper and lower edges of the inner side of the special-shaped transmission belt 32 form outward arc surfaces and inclined surfaces, so that the special-shaped transmission belt 32 can slide from one variable-speed wheel 31 to another variable-speed wheel 31. At the same time, in order to reduce the influence caused by slipping, a plurality of structural grooves are arranged on the inner wall of the special-shaped transmission belt 32, and the plurality of structural grooves are distributed along the length of the special-shaped transmission belt 32; the outer wall of the variable-speed wheel 31 is formed with structural strips of the structural grooves, and the structural strips are on the non-arc surface and inclined surface part of the inner side of the special-shaped transmission belt 32.

[0057] Refer to Figure 4 , when the special-shaped transmission belt 32 switches the variable-speed wheel 31 it sleeves, if the length of the special-shaped transmission belt 32 remains unchanged, there will be situations of being too loose or too tight. Therefore, the present application further includes a coordination wheel 33 and a coordination telescopic unit 35. The coordination wheel 33 is located between the driven wheel 1 and the driving wheel; the coordination telescopic unit 35 includes a tail rod 351, an electric cylinder 352, and a spring 353. The tail rod 351 is fixed to the machine shell. Parallel sleeves are fixed outside the cylinder body of the electric cylinder 352. The sleeves and the spring 353 are sleeved on the tail rod 351, and one end of the spring 353 is fixed to the machine shell and the other end is fixed to the sleeve; the telescopic rod end of the electric cylinder 352 is far from the spring 353 and an installation seat is arranged at the end. The coordination wheel 33 is rotatably connected to the installation seat and abuts against the inner belt surface of the special-shaped transmission belt 32.

[0058] The telescopic rod end of the electric cylinder 352 is fixed with a (spoke type) pressure sensor 354, and the installation seat is fixed on the pressure sensor 354. The pressure sensor 354 is electrically connected to the controller 5, and the controller 5 is configured to:

[0059] Compare the pressure detection value real-time fed back by the pressure sensor 354 with a preset standard pressure detection value, and control the expansion and contraction of the electric cylinder 352 according to the comparison result until the comparison result meets the preset consistency condition, for example: being 0.

[0060] According to the above settings, it is possible to ensure that the special-shaped transmission belt 32 can still rotate relatively stably after the variable-speed wheel 31 is switched.

[0061] In another embodiment of the present application, the gravity strain mechanism 4 includes a bearing platform 41, a lift configuration unit 42, a toothed plate 43, an incomplete gear set 44, and a reverse traction unit 45.

[0062] Among them, the lift configuration unit 42 includes a liquid tank box 421, a connecting pipe 422, and a buffer pipe 423. The liquid tank box 421 is fixed at the position of the machine housing below the container and has an upper opening. One end of the connecting pipe 422 communicates with the bottom of the liquid tank box 421, and the other end communicates with the lower end of the buffer pipe 423. The buffer pipe 423 is vertical and can be built into the vertical support section of the device, and the lower end of the buffer pipe 423 is closed.

[0063] The lower end of the bearing platform 41 extends into the upper opening of the liquid tank box 421 and fixes a piston, and the piston is vertically slidably connected to the liquid tank box 421. The container corresponding to the auger is placed and clamped on the bearing platform 41; the liquid tank box 421 is filled with a medium liquid, such as hydraulic oil. The toothed plate 43 is vertical and fixed to the bearing platform 41 through a bracket. The toothed plate 43 is used to drive the intermittent movement of the incomplete gear set 44, and the incomplete gear set 44 is used to drive the reverse traction unit 45 to push the driven wheel 1 to rise when the toothed plate 43 descends.

[0064] According to the above settings, as long as the weight range and the corresponding relationship of the intermittent movement of the incomplete gear set 44 are allocated, the device can automatically change the transmission ratio of the speed change component 3 as the amount of flour input by the user varies. Moreover, it does not change the transmission ratio for a little more or less flour, but rather when a weight range is reached. For example, it will change when it is short of a pack of 300g of flour, which is more in line with the actual working scenario.

[0065] Considering that the lift of the above lift configuration unit 42 mainly depends on the weight of the liquid squeezed into the buffer pipe 423 when the bearing platform 41 descends, this results in a large demand for the depth of the liquid tank box 421 and the amount of squeezed liquid, which will cause the device to be too large. Therefore, further, the lift configuration unit 42 also includes a counterweight 424. The counterweight 424 is located in the buffer pipe 423 and the lower part is fixedly slidably connected to the piston of the buffer pipe 423. The counterweight 424 is preferably made of a high-density material, such as a lead block wrapped with an alloy; and a retaining bar is fixedly provided at the upper opening of the buffer pipe 423 to prevent the counterweight 424 from falling out.

[0066] In another embodiment of the present application, the incomplete gear set 44 includes a first gear 441, a second gear 442, a transmission gear 443, and a rope reel 444. Among them, the first gear 441 and the transmission gear 443 are coaxially fixed and rotatably connected to the machine housing, and the second gear 442 and the rope reel 444 are coaxially fixed and rotatably connected to the machine housing; there are several teeth on the first gear 441, and the transmission gear 443 meshes with the toothed plate 43; there are multiple tooth grooves on the second gear 442 that are adapted to the first gear 441, and the number of tooth grooves is greater than the number of teeth on the first gear 441. For example, the first gear 441 has one tooth; the first gear 441 meshes with the second gear 442.

[0067] According to the above settings, when the bearing platform 41 drives the toothed plate 43 to descend, the transmission gear 443 rotates and drives the first wheel 441 to rotate; when the first wheel 441 rotates a certain amount, the teeth on it drive the second wheel 442 to rotate once; the second wheel 442 rotates once to drive the rope reel 444 to rotate once, that is, intermittent output.

[0068] Therefore, by selecting the number of teeth of the counterweight 424, the first wheel 441 or the number of tooth grooves of the second wheel 442, it can be determined whether the equipment changes the transmission ratio by adding one more bag of flour or half a bag of flour. The debugging is simple, allowing the user to set it according to their needs.

[0069] In another embodiment of the present application, the reverse traction unit 45 includes a rocker arm 451, a guide rail 452 and a slider 453. The guide rail 452 is fixed to the machine shell and is parallel to the central axis of the driven wheel 1; the slider 453 is slidably connected to the slide rail 452. A rotating shaft is fixed at a position near the middle of the rocker arm 451, and the rotating shaft is rotatably connected to the machine shell. The rocker arm 451 is located above the rope reel 444 and on the side of the guide rail 452, and one end of the rocker arm 451 is tied with a rope, and the other end is a telescopic structure, that is, a large tube body sleeves a small tube body, and the small tube body is hinged to the slider 453. The other end of the above rope is wound around the rope reel 444, and the slider 453 is fixed through an intermediate bracket structure and the outer ring of the bearing sleeved on the outer wall of the driven wheel 1 in advance.

[0070] When the bearing platform 41 descends and drives the rope reel 444 to rotate, the rope reel 444 winds the rope and pulls down the rocker arm 451. At this time, the other end of the rocker arm 451 tilts upward and drives the connected slider 453 to move upward. The upward movement of the slider 453 drives the driven wheel 1 to move upward, that is, the transmission ratio is changed by switching the transmission gear 31.

[0071] According to the above settings, the present application can automatically switch the transmission ratio as the user increases the amount of flour put into the container; after the dough mixing is completed, it can be reset by the self-weight of the driven wheel 1 and the transmission gear 31. To ensure the smooth reset, a reset spring can be fixed to the upper part of the driven wheel 1, the upper end of the reset spring is fixed to the end face fixed top plate, and the end face bearing in the machine shell contacts the top plate.

[0072] It should be noted that the equipment improved by the present application has a characteristic that the equipment is to tilt and mix the dough. At this time, a hidden function prepared in advance by the above settings can be reflected:

[0073] When tilting, the bearing platform 41 moves. During the appropriate tilting angle, the transmission ratio can change and be reset, which exactly matches the dough mixing characteristics during tilting, that is, the load on the auger or the motor will be reduced, because tilting allows the auger to stir the edge of the dough, and in another process, the dough is poured out, that is, the applicability of the present application is better.

[0074] In one embodiment of the present application, the detection mechanism 6 for detecting the action information of the speed change component 3 includes a rotary encoder. The detection end of the rotary encoder is coaxially fixed to the second wheel 442. Thus, every time the rotary encoder detects a rotation, that is, every time a signal is output (not really 1 s, but the signal changes from 0 to 1 and then back to 0), it indicates a change in the transmission ratio. Several outputs mean several speed changes, and it can be determined to which transmission ratio it changes. For example, +1 time corresponds to transmission ratio one; another +1 time means transmission ratio two; -1 time means transmission ratio one, which is actually +1 time and still corresponds to transmission ratio one.

[0075] According to the above settings, due to the position action characteristics of the rotary encoder, the rotary encoder does not need to have a very high precision and the cost is lower. Moreover, as long as the rotary encoder can still output signals, it can be used all the time, and the system stability is higher.

[0076] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
