Description

Technical Field

[0001] The invention relates to the technical field of rice wine processing, in particular to a novel rice wine making machine. Background Art

[0002] As a key equipment for processing raw materials for brewing (such as rice), the function of the brewing rice machine is to efficiently remove impurities such as bran powder and broken rice, and to finely grind and grade the grains to ensure that the brewing raw materials meet high-standard process requirements. The equipment integrates multiple technical links such as screening, grinding, weighing and precise control to achieve comprehensive processing of grains.

[0003] During the research and development and production, our company found that the existing rice wine machine technology still has defects that need to be improved. In the existing technology, rice wine machines generally use the method of rotating the screen drum. Although this method can achieve basic screening functions, the screen assembly is easily damaged due to long-term impact of materials, which affects the screening efficiency and equipment life. At the same time, in order to control the processing volume, the grains in the rice bin will be weighed. Conventional rice wine machines lift the entire refined rice bin through a pull rod mechanism and use a load sensor installed on the top to measure the weight. This weighing method has the problem of inaccurate weighing accuracy and high strength requirements for the screw rod, which increases the complexity and maintenance cost of the equipment. A guide plate is usually equipped at the outlet of the refined rice chamber to assist in the discharge of rice in the refined rice chamber during processing. However, the existing guide plate design cannot be flexibly adjusted according to the situation during the processing, which limits the adaptability and long-term continuous working ability of the equipment, resulting in low efficiency. During the refined rice processing, the discharge flow rate usually uses a linear travel motor and a contact switch combination as an in-place signal to control the flow rate. However, after long-term use, the contact switch is prone to deviation and may even fail to hit the limit, affecting the accuracy and stability of material feeding.

[0004] In summary, although the existing rice wine making machine meets the processing requirements of brewing raw materials to a certain extent, there is still significant room for improvement in efficiency, weighing accuracy, etc. Therefore, a new rice wine making machine is developed to overcome the above shortcomings and improve the overall performance. Summary of the invention

[0005] The purpose of the present invention is to provide a new type of rice wine machine to solve the problems in the background technology that the screen assembly is easily damaged due to long-term impact of materials during the rotation of the screen drum, thus affecting the screening efficiency and the life of the equipment; the grains are weighed in a weighing method in which a pull rod is used to pull up the entire refined rice bin, resulting in inaccurate weighing accuracy; the state of the guide plate cannot be flexibly adjusted according to the situation during the processing, limiting the adaptability of the equipment and its long-term continuous working ability; and the prior art uses a linear stroke motor and a contact switch combination to control the material discharge flow rate.

[0036] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0037] Example:

[0038] This embodiment, in conjunction with the accompanying drawings, introduces this novel rice wine making machine proposed by the present invention.

[0039] like Figure 1 As shown, Figure 1 The three-dimensional structure diagram of a novel rice wine making machine of the present invention is shown in FIG. The novel rice wine making machine comprises: a refined rice bin 4 and a rice pounding chamber 7 arranged at the lower end of the refined rice bin 4, and a hoist 2 is arranged on one side of the refined rice bin 4 and the rice pounding chamber 7;

[0040] A switching valve device 3 is installed at the upper end of the refined rice bin 4, and the switching valve device 3 is arranged on one side of the elevator 2;

[0041] A hoist frame 10 for supporting the hoist 2 is installed on the outer side of the hoist 2;

[0042] A vibrating bran removal device 9 is provided at the lower end of the tamping chamber 7;

[0043] A weighing device 5 and a flow control device 6 are also provided between the refined rice bin 4 and the pounding chamber 7 .

[0044] Combination Figure 2 As shown, Figure 2 Schematic diagram of the structure of the switching valve device in the rice wine machine shown. In the preferred embodiment, in order to improve production efficiency, the switching valve device is designed to have two passages. The switching valve device 3 includes a circulation processing passage 3-1 and a discharge passage 3-2. A switching passage baffle driven by a swing cylinder 3-5 is provided between the two passages to separate the two passages so that the grains can directly enter the selected passage without leakage. At the same time, in order to facilitate direct observation of the state of the grains entering the passage, a direction indicator 3-4 driven by a swing cylinder 3-5 is also designed in the switching device to indicate the direction of the passage. When the fed grains are to enter the selected passage, such as entering the circulation processing passage, the swing cylinder 3-5 drives the switching passage baffle to block the discharge passage 3-2, and at the same time, the swing cylinder 3-5 also drives the direction indicator 3-4 to turn to the circulation processing passage side.

[0045] Furthermore, the discharge port of the circulation processing passage 3 - 1 is connected to the feed port at the upper end of the refined rice bin 4 .

[0046] In order to improve the efficiency of grain screening, a magnetic separation section 3-3 for screening metal objects in grains is also provided on the side of the circulation processing passage 3-1.

[0047] like Figure 3 As shown, Figure 3 Schematic diagram of the structure of the tamping chamber in the rice wine machine. In the preferred embodiment, the discharge port at the lower end of the refined rice bin 4 is connected to the feed port of the tamping chamber, and the grains enter the tamping chamber from the refined rice bin 4, and are ground by the sand roller inside the tamping chamber. The discharge port of the tamping chamber 7 is connected to the vibrating bran removal device 9, and the ground grains enter the vibrating bran removal device 9. Among them, a guide plate 8 controlled by a solenoid valve 11 is provided at the discharge port of the tamping chamber 7. Combined with the pressure in the grinding chamber, the opening and closing size of the guide plate is controlled to ensure the outflow of grains. And the guide plate can be adjusted according to the actual situation during processing.

[0048] In the present invention, the control of the guide plate is completed by the electromagnetic valve, and can be flexibly adjusted according to the situation in the processing process, thereby improving the adaptability and long-term continuous working ability of the equipment and improving the production efficiency.

[0049] Combination Figure 4-6 As shown, Figure 4It is a three-dimensional structural schematic diagram of the vibration bran removal device in the rice wine machine. Figure 5 Schematic diagram of the eccentric shaft in the vibrating bran removal device shown. Figure 6 Schematic diagram of the counterweight block in the vibrating bran removal device shown.

[0050] In a preferred embodiment, the grains after being ground in the tamping chamber enter the vibrating bran removal device. The vibrating bran removal device 9 includes a motor 9-2, a pulley 9-3, a screen assembly 9-4, and an eccentric shaft 9-5 arranged in a housing. The motor 9-2 and the screen assembly 9-4 are both arranged on a bran removal bracket 9-1, and the eccentric shaft 9-5 is arranged on one side of the screen assembly 9-4. The motor 9-2 drives the pulley 9-3 to rotate and rotates the eccentric shaft 9-5 through a coupling, thereby driving the screen assembly 9-4 to move forward and backward and up and down.

[0051] The screen assembly includes a screen mounted on a screen frame, and an elastic ball 9-6 located on the screen, and the elastic ball impacts to separate bran powder from grains. The screen assembly also includes a bran removal cavity, that is, a bran removal space for grains to enter. The screen frame, screen, elastic ball, etc. are all located in the bran removal cavity. When grains enter the bran removal cavity, the screen cooperates with the elastic ball to impact and separate bran powder and broken rice in the grains.

[0052] In the preferred embodiment, an eccentric shaft is designed to enable the screen to move up, down, left, and right to achieve a vibration effect. However, the design of the eccentric shaft also makes it easy for the screen to vibrate too much during the vibration bran removal process, resulting in the screen being easily damaged and the bran screening effect being poor. For this reason, a counterweight block 9-7 is provided on one side of the pulley to offset the impact of the eccentric shaft rotation on the vibration of the screen assembly to prevent the screen from vibrating too much.

[0053] In the preferred embodiment, the screen assembly can be replaced with screens of different mesh sizes according to different processing processes. A handle 9-8 is provided at one end of the screen frame for facilitating the pulling out of the screen assembly, and detachable bolts 9-9 are provided on both sides of the handle 9-8. The detachable bolts install the screen frame on the bran removal chamber. When maintenance is required, the housing of the vibrating bran removal device is opened, and then the detachable bolts on the screen assembly are removed, and the screen assembly can be manually pulled out through the handle, which is simple, convenient and easy to replace.

[0054] In a preferred embodiment, the screen assembly 9-4 further includes a bran discharge port 9-10 for discharging bran powder and broken rice, and a circulation port 9-11 connected to the feed channel. After passing through the screen assembly, the powder and the like in the grains are completely separated from the grains, and the screened bran powder and broken rice are directly discharged from the bran discharge port. The circulation port is connected to the feed channel. Under the action of the elevator, the screened grains are sent from the circulation port to the circulation processing passage 3-1 through the elevator, and the bran is removed according to the processing requirements.

[0055] In the preferred embodiment, the novel rice wine machine designed by the present invention can not only realize the vibration removal of bran from grains, but also can carry out cyclic processing of grains according to processing requirements, and can also accurately weigh grains.

[0056] like Figure 7 As shown, Figure 7 It is a three-dimensional structural schematic diagram of the weighing device and flow control device in the rice wine machine shown.

[0057] The weighing device 5 is located at the lower end of the polished rice bin 4 and is mounted on the L bracket 12. The weighing device 5 includes a plurality of weighing units. In order to improve the accuracy of weighing, the plurality of weighing units are evenly distributed along the circumference of the polished rice bin.

[0058] In a preferred embodiment, three groups of weighing units are arranged, evenly distributed along the polished rice bin, forming a three-point distribution structure. The three-point distribution structure improves the accuracy and stability of the weighing structure. When the grains enter the polished rice bin, the three weighing units respectively detect the weight data of three different positions of the polished rice bin, sum the three weight values, and calculate the average value. The final output grain weight value is the calculated average value.

[0059] This weighing device belongs to the existing technology. The weighing unit can choose a variety of pressure measurement methods to achieve, which will not be described in detail. If the weighing unit chooses a strain gauge weighing sensor, the weighing principle is similar to the weighing principle of an electronic scale. A strain gauge weighing sensor is set at the bottom of the refined rice bin. When the grain enters the refined rice bin, the weight of the refined rice bin is transmitted to the sensor through the supporting structure, causing the elastic body inside the sensor to deform. The sensor converts the weight into an electrical signal. Since the electrical signal output by the sensor is usually weak and needs to be amplified, the electrical signal is amplified in the electric control cabinet, and the amplified signal is output to the control display screen for the operator to read and record.

[0060] The three-point design is more stable in structure and makes the measurement more accurate. The obtained weight is converted and reflected on the matching touch screen.

[0061] In the preferred embodiment, the storage capacity of the polished rice bin 4 is relatively large. In order to avoid the situation of poor flow and blockage when the grains are discharged from the polished rice bin 4, the present invention designs a flow control device 6 between the polished rice bin 4 and the pounding chamber 7. The flow control device not only controls the discharge flow, but also assists the weighing device in weighing the grains in the polished rice bin 4, and plays the role of cutting off the discharge port at the lower end of the polished rice bin 4 and placing the grains for discharge.

[0062] like Figure 8 As shown, Figure 81 is a schematic diagram of the structure of the flow control device. The flow control device 6 is installed on the L bracket 12, and the flow control device 6 includes a flow valve 6-1 for adjusting the discharge flow of the refined rice bin 4, and a cylinder 6-2 for driving the flow valve 6-1. The flow valve 6-1 is located at the lower end of the refined rice bin 4;

[0063] A number of limit switches 6-4 are arranged on the cylinder 6-2. The limit switches 6-4 correspond to a number of flow gears on the flow valve 6-1. The cylinder 6-2 drives the flow valve 6-1 upward or downward to reach the selected flow gear. The limit switch 6-4 locks the cylinder after receiving the signal. For example, when the cylinder stroke rod moves downward, the flow valve 6-1 is lifted up by the force arm 6-3 to reach the selected flow gear. When the position switch receives the signal, the cylinder is locked. The appropriate gear is selected by observing the grain grinding situation to adjust the grain discharge flow rate. At the same time, when weighing the grain, the pneumatic drive force arm completely lifts the flow valve and closes the discharge port of the refined rice bin for easy weighing.

[0064] In a preferred embodiment, six limit switches are provided on the cylinder, corresponding to the six gears of the flow valve respectively. The limit switches form six gears from 0 to 5, 0 being fully closed and 5 being fully open. When the corresponding gear is reached, the indicator light comes on.

[0065] The working principle of the wine and rice machine:

[0066] Feeding stage: the grains to be processed enter through the feeding platform 1, and the elevator 2 transports the grains along the feeding channel to the switching valve 3;

[0067] Passage selection: The switching valve 3 selects the passage according to the processing stage. The primary processing or the circulating processing selects the circulating processing passage, and the grains enter the polished rice bin 4; the grains after processing are discharged through the discharge channel 3-2;

[0068] Processing of polished rice bin: whether to weigh depends on the processing requirements. The weighing is completed by the weighing device 5. The unprocessed grains and the processed grains can be weighed and then enter the subsequent processing flow;

[0069] Grain grinding: The grain is ground in the pounding chamber 7, and the processed grain passes through the automatic copper separator and the guide plate 8 at the discharge port to adjust the grain flow direction, and enters the vibrating bran removal screen device 9 for bran removal;

[0070] Bran removal: The grains are screened out of bran powder and broken rice in the vibrating bran removal device 9 under the action of the bran screening assembly, etc. The screened bran powder and broken rice are discharged through the bran discharge port 9-10, and the remaining grains (qualified grains) are determined according to the processing requirements to determine whether to be recycled and processed;

[0071] Circular processing logic: If further processing is required, qualified grains return from the circulation port 9-11, pass through the feed channel and the circular processing passage 3-1 and re-enter the polished rice bin 4. The number of cycles is determined by the processing step requirements (target accuracy or weight). Each cycle can repeat the weighing, pounding and bran removal steps;

[0072] Finished product discharge: After processing is completed, the switching valve 3 switches to the discharge passage, and the grains are discharged through this passage.

[0073] The new type of rice wine machine designed by the present invention has a more compact overall structure, reduces the space occupied, and can be processed in multiple cycles according to production needs, thereby improving production efficiency; at the same time, the processing volume is also increased, and the processing volume is changed from the original 900kg to 24000kg, and the processing volume is increased, which is more in line with market demand. Through the design of the vibration bran removal device, the efficiency of bran screening is significantly improved, the screen is not easy to be damaged, and the replacement is convenient for subsequent maintenance. The weighing device is more stable in structure, and the weighing unit is evenly distributed along the circumference of the refined rice bin, and the measured value is averaged to obtain the final weight value, which greatly improves the weighing accuracy and stability. After actual production testing, the measurement accuracy error does not exceed ±5kg (processing volume is 2.4t), which solves the problem of inaccurate weighing accuracy in the prior art of weighing grains by using a pull rod to pull up the entire refined rice bin. The design of the guide plate also improves the flexibility of use, and the state of the guide plate can be changed in real time according to the variety of rice and the processing situation, which can well control the outflow of grains, is conducive to processing accuracy, and can also prevent the machine from being stuck. The design of the flow control device enables the rice wine machine to better control the grain discharge flow rate during use. It is simple to operate and solves the problem in the prior art of controlling the discharge flow rate by using a combination of a linear travel motor and a contact switch. Under long-term use, the contact switch is prone to deviation and may even fail to touch the limit. The cylinder structure is relatively stable, with improved safety performance.
