Description

TECHNICAL FIELD

[0001] The present application belongs to the technical fields of piezoelectric sensor research and sticky rice processing, and specifically relates to a sticky rice primary processing device and method based on piezoelectric sensor feedback control. BACKGROUND

[0002] Sticky rice is a traditional Chinese delicacy that is particularly popular in southern regions, especially in Zhejiang, Hunan, Guizhou, Chongqing, and Sichuan, due to its unique chewy texture and cultural significance. It is meticulously crafted through a series of manual processes such as steaming and pounding, resulting in a product that is not only delicate and elastic but also rich in nutrients, often served as a treat for guests during festivals and celebrations.

[0003] However, the traditional manual production process of sticky rice is quite laborious, particularly the step of pounding the glutinous rice, which requires a great deal of physical effort and is inefficient. This process involves workers repeatedly swinging heavy mallets, not only consuming physical energy but also making it difficult to maintain product consistency. As the pace of modern life accelerates, traditional manual production methods have become unable to meet market demand, and have also placed a significant physical burden on workers engaged in this labor.

[0004] Despite the trend towards mechanization and automation in modern industry, the automated production of sticky rice faces numerous challenges. First, the texture and taste of sticky rice have very high requirements for the force, speed, and uniformity of pounding, which poses stringent conditions for the design of mechanical devices. Second, the sticky and elastic properties of glutinous rice make it prone to sticking and clumping during processing, posing challenges for automated control. In addition, as a traditional food, consumers have specific expectations for the flavor and appearance of sticky rice, and automated production must also ensure that the product can maintain the unique flavor and texture of traditional handmade production.

[0040] Push box 2-4 is divided into a blocking section and a waxy rice carrying section connected in sequence.The blocking section is located on the side of the waxy rice carrying section away from conveying assembly 2-5.The top of the blocking section is a closed plane, and the height of the top of the blocking section matches the height of the bottom output port of hopper 2-2.A waxy rice quantitative chamber is provided in the waxy rice carrying section.The top and bottom of the waxy rice quantitative chamber are both provided with openings.

[0041] The first hydraulic cylinder 2-1 is installed on the frame 1, and the push rod is fixed with the push box 2-4. Under the drive of the first hydraulic cylinder 2-1, the push box 2-4 has two working positions, which are the receiving position and the output position respectively. When the push box 2-4 is in the receiving position, the waxy rice carrying section is below the hopper 2-2, and the waxy rice in the hopper 2-2 is input into the waxy rice quantitative chamber until the waxy rice quantitative chamber is filled. When the push box 2-4 is in the output position, the bottom opening of the waxy rice quantitative chamber in the waxy rice carrying section is above the conveying assembly 2-5, so that the waxy rice in the waxy rice quantitative chamber falls onto the conveying assembly 2-5; at the same time, the blocking section is below the hopper 2-2, and the waxy rice in the hopper 2-2 is prevented from leaking out.

The shape of the auxiliary push plate 2-6-3 matches the cross section of the waxy rice quantitative chamber. The auxiliary push plate 2-6-3 is located directly above the waxy rice quantitative chamber of the push box 2-4 in the output position. The downward movement of the auxiliary push plate 2-6-3 can push the waxy rice adhering to the side wall of the waxy rice quantitative chamber to the conveying assembly 2-5.

[0043] As shown in FIGS. Figure 2 , 4 and 5, the turnover hammer mechanism 3 includes an outer frame 3-1, a hammer container 3-2, a rotating disc 3-3, a supporting assembly 3-4, a hammer drive assembly 3-5, a central fixed shaft 3-6, a gear disc 3-7, two guide columns 3-8 and three hammer execution assemblies 3-9. The outer frame 3-1 includes a top plate and a plurality of vertical columns. The bottom ends of the plurality of vertical columns are fixed on the frame 1. The top ends of the plurality of vertical columns are fixed with different edge positions of the bottom surface of the top plate respectively. The top end of the central fixed shaft 3-6 with the vertical axis is fixed with the middle part of the top plate. The bottom end of the central fixed shaft 3-6 is rotatably connected with the central position of the rotating disc 3-3 through a bearing. The gear disc 3-7 is located below the rotating disc 3-3 and is coaxially fixed with the rotating disc 3-3 through a plurality of connecting columns.

[0044] Each of the columns is provided with a supporting assembly 3-4. The supporting assembly 3-4 comprises a supporting frame 3-4-1 and a roller 3-4-2. The supporting frame 3-4-1 is fixed on the corresponding column. The roller 3-4-2 is rotatably connected to the top surface of the supporting frame 3-4-1. The axis of the roller 3-4-2 is perpendicular to the axis of the rotating disc 3-3. The bottom edge of the rotating disc 3-3 is in contact with each of the rollers 3-4-2. Each of the rollers 3-4-2 supports the rotating disc 3-3 without affecting the rotation of the rotating disc 3-3, which helps to improve the stability of the rotating disc 3-3.

[0045] The beating execution assembly 3-9 comprises a fixed bevel gear 3-9-1, a movable bevel gear 3-9-2, a connecting rod 3-9-3 and a beating column 3-9-4. The fixed bevel gear 3-9-1 is coaxially fixed on the central fixed shaft 3-6. The movable bevel gear 3-9-2 with the axis horizontally arranged is rotatably connected to the rotating disc 3-3 through a connecting bracket. The movable bevel gear 3-9-2 is in mesh with the fixed bevel gear 3-9-1. The gear disc 3-7 is provided with three guide holes corresponding to the positions of the beating columns 3-9-4 in the three beating execution assemblies 3-9, respectively.

The other end of the connecting rod 3-9-3 is rotatably connected to the top end of the extension rod.

[0046] When the gear disc 3-7 drives the rotating disc 3-3 to rotate, the movable bevel gear 3-9-2 rotates around the central fixed shaft 3-6 while revolving, and further drives the beating column 3-9-4 to move up and down through the connecting rod 3-9-3.

[0047] The fixed bevel gears 3-9-1 in the three beating execution assemblies 3-9 are arranged along the axis of the central fixed shaft 3-6 in sequence, and the diameters decrease from top to bottom, so that the beating columns 3-9-4 in the three beating execution assemblies 3-9 gradually approach the center of the beating container 3-2, so as to knock the glutinous rice cakes at different positions. At the same time, the diameters of the three movable bevel gears 3-9-2 are equal, so that the beating speed of the beating column 3-9-4 farther away from the center of the beating container 3-2 is faster.

[0048] The two guide columns 3-8 both pass through the gear disc 3-7, and the top ends are fixed to the bottom surface of the rotating disc 3-3. One of the two guide columns 3-8 is connected to the position close to the edge of the bottom surface of the rotating disc 3-3. The other guide column 3-8 is connected to the position close to the center of the bottom surface of the rotating disc 3-3.

[0050] The beating driving assembly 3-5 includes a beating driving motor 3-5-1 and a driving gear 3-5-2. The beating driving motor 3-5-1 is fixed on the rack 1. The driving gear 3-5-2 is fixed with the output shaft of the beating driving motor 3-5-1. The driving gear 3-5-2 is engaged with the gear teeth on the outer circumference of the gear disc 3-7, so as to drive the gear disc 3-7 to rotate, and then drive the beating column 3-9-4 to lift and rotate around the center of the beating container 3-2.

[0051] The discharging mechanism 4 includes a second hydraulic cylinder 4-1, a beating bottom sealing plate 4-2, a receiving container 4-3, a bearing disc 4-4, a second piezoelectric sensor 4-5 and a pushing output assembly 4-6. The beating container 3-2 is provided with a bottom opening. The receiving container 4-3 is fixed on the rack 1, and the top opening is located directly below the bottom opening of the beating container 3-2. The bearing disc 4-4 is arranged at the bottom of the inner cavity of the receiving container 4-3; the second piezoelectric sensor 4-5 is installed between the bearing disc 4-4 and the bottom surface of the inner cavity of the receiving container 4-3.

[0052] The side wall bottom of the beating container 3-2 is provided with a slot. The beating bottom sealing plate 4-2 is arranged at the bottom of the beating container 3-2 and seals the bottom opening of the beating container 3-2. The edge of the beating bottom sealing plate 4-2 is clamped into the clamping slot on the inner side wall of the beating container 3-2, so as to facilitate the beating bottom sealing plate 4-2 to bear the hammering force. The beating bottom sealing plate 4-2 is in sliding connection with the bottom of the beating container 3-2 and can be pulled out of the slot. The second hydraulic cylinder 4-1 is installed on the rack 1, and the outer end of the push rod is fixed at the edge of the beating bottom sealing plate 4-2. The second hydraulic cylinder 4-1 is used to drive the beating bottom sealing plate 4-2 to be inserted into or pulled out of the bottom of the beating container 3-2; so that the sticky rice cake completed beating in the beating container 3-2 can automatically fall into the receiving container 4-3.

[0053] The push-out assembly 4-6 comprises a third hydraulic cylinder 4-6-1 and a push-out disc 4-6-2. A central hole is formed in the gear disc 3-7. The third hydraulic cylinder 4-6-1 is fixed at the center of the bottom surface of the rotating disc 3-3, and the push-out rod is vertically arranged downward. The push-out rod of the third hydraulic cylinder 4-6-1 passes through the central hole of the gear disc 3-7 and is fixed at the center of the push-out disc 4-6-2. The outer contour of the push-out disc 4-6-2 matches the cross-sectional shape of the inner cavity of the beating container 3-2. The push-out disc 4-6-2 is provided with a scraping hole corresponding to the positions of the beating columns 3-9-4 and the guide columns 3-8, respectively, and matching in size. The third hydraulic cylinder 4-6-1 is used to push the push-out disc 4-6-2 to move downward, so that the push-out disc 4-6-2 enters the inner cavity of the beating container 3-2, and the sticky rice adhering to the inner side wall of the beating container 3-2, the beating columns 3-9-4 and the guide columns 3-8 is pushed out into the bearing container.

[0054] As shown in Figure 6 the working method of the sticky rice initial processing device based on piezoelectric sensor feedback control, comprising the following steps:

[0055] Step one, place the steamed glutinous rice in the hopper 2-2. When the production line has not started to run, the front square opening of the push box 2-4 is aligned with the lower square opening of the hopper 2-2.

[0056] Step two, start the first hydraulic cylinder 2-1 to control the push box 2-4 to move to the right, and when the lower part of the square opening of the push box 2-4 is just completely exposed, the first hydraulic cylinder 2-1 stops moving, and the glutinous rice in the square opening of the push box 2-4 will fall onto the lower belt conveyor 2-5-1 under the action of its own weight. At this time, it is necessary to analyze the actual situation. As we all know, the steamed glutinous rice has a certain viscosity between them, when the push box 2-4 moves to the right to the specified position, the glutinous rice in the square opening of the push box 2-4 may not fall on the lower belt conveyor 2-5-1 in time due to adhesion.

[0057] At this time, a piezoelectric sensor needs to be added for feedback auxiliary control; the specific scheme is: first, with the help of external tools, the same weight of glutinous rice is dropped multiple times from the same height between the push box 2-4 and the belt conveyor 2-5-1, and the piezoelectric sensor will collect many groups of voltage data. Through the analysis and integration of these data, we will get a voltage value that is most suitable for fitting, and set 0.8 times of this value as the feedback warning voltage value of the piezoelectric sensor. This warning voltage value setting can play a role in that the piezoelectric sensor will immediately give a feedback signal once it monitors a voltage signal greater than this warning voltage value; if no voltage value is monitored or the measured voltage value is less than this warning voltage value, no feedback signal will be given.

[0058] The feedback auxiliary control applied to the actual device of the present application can realize the function of: we need a timer, when the push box 2-4 moves to the right to the specified position, start timing immediately for five seconds, if the first piezoelectric sensor 2-5-2 does not give a feedback signal after five seconds, it means that the glutinous rice has not fallen down completely, and the auxiliary hydraulic cylinder 2-6-2 will receive a signal to start immediately, driving the auxiliary push plate 2-6-3 to make a reciprocating motion. The movement stroke of the auxiliary push plate 2-6-3 needs to be determined according to the actual height of the machine. When the auxiliary push plate 2-6-3 returns to the starting position, a signal is immediately transmitted to the first hydraulic cylinder 2-1 to drive the push box 2-4 to return to the original position, and the belt conveyor 2-5-1 and the beating driving motor 3-5-1 are started, the belt conveyor 2-5-1 is set to rotate for one minute, and the time is automatically stopped after one minute. The beating driving motor 3-5-1 can be set to work for 15 minutes. If the first piezoelectric sensor 2-5-2 gives a feedback signal after five seconds, it means that the glutinous rice has fallen down on the pressure plate of the first piezoelectric sensor 2-5-2 under the action of its own weight, and only a signal is immediately transmitted to the first hydraulic cylinder 2-1 to drive the push box 2-4 to return to the original position and the belt conveyor 2-5-1 and the beating driving motor 3-5-1 to start immediately.

[0059] When 15 minutes are up, the glutinous rice has been beaten, and the second hydraulic cylinder 4-1 immediately drives the beating bottom cover plate 4-2 to move to the right, so that the beaten glutinous rice primary product falls into the receiving container 4-3.

[0060] Here, we also need to analyze the actual situation, from our actual manual beating process, the beaten glutinous rice primary product has greater viscosity, so we also need to add another feedback auxiliary control as mentioned in the previous text.

[0061] The feedback auxiliary control of the second piezoelectric sensor 4-5 is implemented as follows: when the second hydraulic cylinder 4-1 drives the beating bottom sealing plate 4-2 to move to the right to the rightmost position, a timer is still needed to count for five seconds, and after five seconds, if the second piezoelectric sensor 4-5 does not transmit a feedback signal, it indicates that the initial product of sticky rice cakes does not fall into the collection container successfully, and then the third hydraulic cylinder 4-6-1 is immediately started to drive the discharging push plate 4-6-2 to move downward. After moving to the specified position, it is automatically reset immediately, and after the reset is completed, a signal is transmitted to make the second hydraulic cylinder 4-1 drive the beating bottom sealing plate 4-2 to reset. If the second piezoelectric sensor 4-5 transmits a feedback signal, it indicates that the initial product of sticky rice cakes has fallen into the collection container, and then the second hydraulic cylinder 4-1 is directly reset.

[0062] Step three: after the second hydraulic cylinder 4-1 is reset, if the hopper 2-2 still has sticky rice that can support the work load of one beating operation, a signal is transmitted to start the first hydraulic cylinder 2-1 again, so that a new beating operation is started; if the hopper 2-2 has no sticky rice or the remaining sticky rice is insufficient to support the work load of one beating operation, a signal is not transmitted to start the first hydraulic cylinder 2-1 again, and an alarm is issued to remind the worker to add sticky rice to the hopper 2-2 in time. After the sticky rice is added, the worker starts the first hydraulic cylinder 2-1 again to start a new operation.
