Description

Technical Field

[0001] The present invention relates to the technical field of grain milling machinery and equipment in the grain processing industry, and more specifically to an intelligent quality control milling machine. Background Art

[0002] At present, grain processing technology has reached a relatively high level. However, as people's living standards continue to improve, their requirements for grain processing quality are also increasing, which prompts the grain processing industry to continuously improve its technological level. The ensuing problem is that the current grain processing equipment is not intelligent enough, which restricts the development requirements of grain processing technology.

[0003] In particular, the mill in the prior art has a large workload and difficulty in operation. For example, patent application document CN 1436601A discloses a high-speed mill, which is composed of a feeding cylinder (1), a baffle plate (2), a rear feeding roller (3), a feeding door (4), a front feeding roller (5), a feeding plate (6), a guide plate (7), a fast grinding roller (8), a slow grinding roller (9), a grinding brush (10), an air suction duct (11), a receiving hopper (12), a machine body (13), a feeding motor (14), a fast and slow grinding roller transmission system (15), a rolling distance adjustment mechanism (16), and an electrical box (17). Patent application document JPS5311757A discloses a method and device for grinding grain into powder, wherein the mill and the rolling distance adjustment mechanism of the mill are disclosed in detail.

[0004] At present, in the mills similar to those in the patent application documents CN 1436601A and JPS5311757A, the miller is mostly operated manually by relying on personal experience, observing the grinding condition through manual senses and then manually operating the electrical box to adjust the rolling distance adjustment mechanism (16), thereby adjusting the quality of the grinding. This easily leads to poor product quality stability, a large number of unqualified products, an increase in the number of returned machines, and a longer production cycle for the same number of products that meet the product quality requirements, which invisibly increases the production cost.

[0005] A more advanced operation mode is to use manual sampling, offline analysis, and then manually adjust the rolling distance adjustment mechanism (16) to adjust the quality of the ground powder. However, the manual sampling and manual adjustment steps are carried out in the production workshop, and the offline analysis is carried out in the laboratory. It is necessary to go back and forth between the production workshop and the laboratory. The whole process is time-consuming and laborious. The grinding process is very fast. By the time the test results are obtained and the rolling distance of the grinding roller is manually adjusted, many unqualified products may have been produced. Moreover, one adjustment may not be in place and multiple re-inspections are required to adjust the rolling distance to a suitable range, resulting in more unqualified products. Therefore, this method cannot timely adjust the quality of the ground powder. If the grinding roller rolling distance is adjusted after the machine is shut down to wait for the test results, the production efficiency will be greatly affected.

[0006] It can be seen that it is difficult for the mill in the prior art to control the grinding quality in a timely and effective manner, and there is still room for further improvement. Summary of the invention

[0007] The purpose of the present invention is to provide an intelligent quality control grinding mill to solve the above technical problems. The grinding mill can detect the quality of ground powder online and adjust the grinding roller spacing in real time to regulate the quality of ground powder.

[0013] Furthermore, the area of ​​the sampling feed port is 1 / 2-4 / 5 of the top surface area of ​​the auger box.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0033] like Figures 1 to 7 As shown, this embodiment provides an intelligent quality control mill. The intelligent quality control mill includes a mill body, which includes a body 1, a control box 2, a feed bin mechanism 3, an automatic feeding mechanism 4, a grinding mechanism 5, and a discharge bin mechanism 6. The grinding mechanism 5 includes a fast grinding roller 51, a slow grinding roller 52, an automatic rolling distance adjustment mechanism 53, a rolling distance display mechanism 54, and a grinding roller cleaning mechanism 55. An automatic sampling auger mechanism 7 is arranged between the grinding mechanism 5 and the discharge bin mechanism 6. A grinding detector 8 is also arranged outside the mill body. The sampling feed port 71 of the automatic sampling auger mechanism 7 can be opened and closed, and the sampling discharge port 72 of the automatic sampling auger mechanism 7 is connected to the inspection feed port 82 of the grinding detector 8 through a standby inspection feed pipe 81. The automatic sampling auger mechanism 7, the grinding detector 8, and the automatic rolling distance adjustment mechanism 53 are all electrically connected to the control box 2.

[0034] Working principle: After the intelligent quality control mill starts grinding materials and stabilizes, the control box 2 issues a command according to the system parameters set in advance to drive the automatic sampling auger mechanism 7 to perform sampling work, and wait until the sample taken out by the automatic sampling auger mechanism 7 completely enters the grinding detector 8 through the sampling outlet 72, the inspection feed pipe 81, and the inspection feed port 82. Then, the control box 2 drives the grinding detector 8 to detect the indicators reflecting the grinding effect, such as the scraping rate, powder output rate or particle size distribution, and uploads the detected data to the control box 2, and the material after the test is unloaded through the inspection outlet 83 of the grinding detector 8. At the same time, after the control box 2 receives the detection data from the grinding detector 8, it compares it with the set parameters in the control system, and issues instructions based on the comparison results to control the automatic rolling distance adjustment mechanism 53 to appropriately adjust the grinding roller rolling distance; when the grinding roller rolling distance is adjusted to a certain range, the sampling and detection work is repeated again, and the grinding roller rolling distance is automatically adjusted again according to the detection results until the process design requirements are finally met; when the grinding mill rolling distance meets the process design requirements, sampling can be stopped; in addition, the sampling and detection work can be repeated multiple times at intervals through the program time set in advance to ensure the stability of the grinding quality.

[0035] like Figure 2 As shown, the mill body 1 in the prior art generally adopts two sets of front and rear feeding bin mechanisms 3, automatic feeding mechanism 4, grinding mechanism 5, and discharging bin mechanism 6. Therefore, the intelligent quality control mill of the present invention also includes two sets of independent automatic sampling auger mechanisms 7 and grinding detectors 8. The two automatic sampling auger mechanisms 7 can be as shown in FIG. Figure 1 and Figure 2 As shown in the figure, they are arranged in a centrally symmetrical form, or as Figure 3 and Figure 6 The front and rear axes are arranged symmetrically as shown.

[0036] It should be understood that the grinding effect of the mill is an important indicator for producing qualified products. The parameters reflecting the grinding effect include the scraping rate, powder yield, particle size distribution and other indicators. These important indicators can be detected by the grinding detector 8. As for the specific structure of the grinding detector 8, it belongs to the prior art and is not the focus of the present invention, so it will not be repeated here. The parameters reflecting the grinding effect of the mill at different positions are different and adapted. The indicators detected by the grinding detector 8 are also different, and the basis for adjusting the rolling distance is naturally different. For example, when the mill body 1 is a skin grinder, the rolling distance is mainly adjusted by detecting the scraping rate. When the scraping rate detection result is lower than the set range, the rolling distance needs to be reduced, otherwise the rolling distance is increased; when the mill body 1 is a core grinder, the grinding detector 8 mainly adjusts the rolling distance by detecting the powder yield. When the powder yield detection result is lower than the set range, the rolling distance needs to be reduced, otherwise the rolling distance is increased.

[0037] It is understandable that the control box 2, as the control center of the intelligent quality control mill, can not only complete the functions of information collection, data analysis, judgment and calculation, and command output, but also bear the functions of data communication transmission, etc., record the process of information collection, data analysis, judgment and calculation, and command output, and upload it to the CP workstation, server and other terminals that need to receive these data through wired / wireless data transmission functions. How the control box 2 automatically controls the automatic sampling auger mechanism 7, the grinding detector 8 and the grinding mechanism 5, its operating mechanism and calculation algorithm are not the focus of the present invention.

[0038] As for the specific structure of the automatic rolling distance adjustment mechanism 53, it can also be set with reference to the prior art, which is not the focus of the present invention and will not be described in detail here.

[0039] Although the intelligent quality control grinding mill provided in this embodiment can complete the tasks of timed automatic sampling, grinding quality detection, automatic adjustment of rolling distance, etc. according to the parameters set in advance, it can be understood that the intelligent quality control grinding mill has a rolling distance display mechanism 54, and can also be manually operated on the control panel of the control box 2 to issue instructions to complete the above-mentioned rolling distance adjustment work according to the grinding effect detection results. Example 2

[0040] Based on the first embodiment, the structure of the automatic sampling auger mechanism 7 is described in detail in this embodiment.

[0041] like Figure 4 and Figure 5 As shown, the automatic sampling auger mechanism 7 includes: an auger box 73, a conveying auger 74, a conveying screw motor 75, a box fixing part 76, a sampling feed port 71, a sliding cover 77 and a sampling discharge port 72. The conveying auger 74 is arranged in the auger box 73, and the conveying auger 74 is driven by the conveying screw motor 75. The auger box 73 is provided with a box fixing part 76 for connecting with the inner wall of the grinding chamber of the machine body 1. The top of the auger box 73 is provided with a sampling feed port 71, and the sampling feed port 71 is slidably connected with a sliding cover 77, which is driven to open and close by a sliding cover driving mechanism 78. The bottom of the auger box 73 is provided with a sampling discharge port 72.

[0042] Working principle: When collecting samples, the control box 2 issues a command to drive the slide cover drive mechanism 78 to open the slide cover 77, allowing the material to enter the auger box 73 through the sampling feed port 71. The control box 2 can set the sampling time. After the sampling time is over, the control box 2 drives the slide cover drive mechanism 78 to close the slide cover 77, and the material can no longer enter the auger box 73. Then, the control box 2 drives the conveying screw motor 75 to convey the material through the sampling outlet 72 and enter the grinding detector 8 from the inspection feed pipe 81 and the inspection feed port 82. The automatic sampling auger mechanism 7 adopts the feeding method of the movable slide cover 77. As long as the sampling time is controlled the same, it can basically ensure that the number of samples is basically the same each time, which is convenient for adapting to the requirements of the sampling number for subsequent quality inspections and maintaining the accuracy of the test results.

[0043] In a possible implementation manner, the specific structure of the sliding cover driving mechanism 78 is as follows: Figure 5 As shown, the slide cover driving mechanism 78 includes: two rails 781, two sliders 782, a rack 783, a reduction motor 784, and a gear 785. The top of the auger box 73 is located on the left and right sides of the sampling feed port 71, and the rails 781 are fixed in parallel and symmetrically. The slide cover 77 is mounted on the top of the two sliders 782 and is slidably connected to the rails 781 through the sliders 782. The rack 783 is fixed on the top of the auger box 73 and is parallel to the rails 781. The reduction motor 784 is fixed at one end of the slide cover 77 and a gear 785 meshing with the rack 783 is provided on the output shaft of the reduction motor 784.

[0044] In another possible implementation, the specific structure of the sliding cover driving mechanism 78 is as follows: Figure 6 and Figure 7 As shown, the slide cover driving mechanism 78 includes: two rails 781, two sliders 782, and a cylinder 786. The top of the auger box 73 is located on the left and right sides of the sampling feed port 71, and the rails 781 are fixed in parallel and symmetrically. The slide cover 77 is mounted on the top of the two sliders 782 and is slidably connected to the rails 781 through the sliders 782. The cylinder 786 is horizontally arranged, and the bottom of the cylinder 786 is fixed on the inner wall of the grinding chamber of the body 1. The telescopic shaft of the cylinder 786 is connected to the side wall of the slide cover 77.

[0045] Further, if Figure 1 and Figure 2 As shown, the automatic sampling auger mechanism 7 and the fast grinding roller 51 and the slow grinding roller 52 are parallel to each other. Figure 2As shown, the sampling feed port 71 is directly opposite to the position between the fast grinding roller 51 and the slow grinding roller 52. It can be understood that, under the condition of a certain number of samples, the larger the corresponding overlapping area of ​​the automatic sampling auger mechanism 7 and the grinding mechanism 5, the easier it is for the material to enter the auger box 73, the shorter the time spent on the sampling process, the more timely the quality inspection and the adjustment of the rolling distance can be guaranteed, the fewer unqualified products there are, and the better the overall grinding quality can be guaranteed. As for the width of the automatic sampling auger mechanism 7, as long as the material can fall into the sampling feed port 71, for example, the width of the automatic sampling auger mechanism 7 can be greater than the rolling distance and less than or equal to 1 / 3 of the distance between the central axes of the fast grinding roller 51 and the slow grinding roller 52; as for the length of the automatic sampling auger mechanism 7, it can be less than or equal to the length of the fast grinding roller 51 and the slow grinding roller 52, for example, the length of the automatic sampling auger mechanism 7 is equal to the length of the fast grinding roller 51 and the slow grinding roller 52.

[0046] On the basis that the automatic sampling auger mechanism 7 and the fast grinding roller 51 and the slow grinding roller 52 are parallel to each other, further, the sliding direction of the sliding cover 77 and the conveying direction of the conveying auger 74 are perpendicular to each other, that is, the sliding cover 77 slides forward and backward to realize opening and closing, and the conveying auger 74 conveys materials to the left or right. The purpose of this arrangement is to facilitate the opening of the sliding cover 77 within the limited space of the machine body 1, and to expose the sampling feed port 71 as much as possible, so that when sampling is required, the material can fall into the auger box 73 as soon as possible, thereby shortening the sampling time, helping to quickly adjust the grinding roller rolling distance, and reducing the amount of unqualified products.

[0047] On the basis that the automatic sampling auger mechanism 7 and the fast grinding roller 51 and the slow grinding roller 52 are parallel to each other, further increasing the size of the sampling feed port 71 itself can naturally make the material fall into the auger box 73 as soon as possible. It can be understood that, under the condition of a certain number of samples, the larger the area of ​​the sampling feed port 71, the larger the area corresponding to the overlap of the grinding mechanism 5, and the easier it is for the material to enter the auger box 73, the shorter the time spent in the sampling process, the more timely the quality inspection and rolling distance adjustment can be guaranteed, the fewer unqualified products there are, and the better the overall grinding quality can be guaranteed. Therefore, in this embodiment, the area of ​​the sampling feed port 71 is set to 1 / 2-4 / 5 of the top surface area of ​​the auger box 73. Furthermore, the area of ​​the sampling feed port 71 is preferably 2 / 3-4 / 5 of the top surface area of ​​the auger box 73.

[0048] Further, if Figure 4 As shown, the automatic sampling auger mechanism 7 also includes an auger blockage detection mechanism 79, which is arranged on the auger box 73 just above the corresponding sampling outlet 72. The auger blockage detection mechanism 79 is used to detect the operating status of the automatic sampling auger mechanism 7 to prevent the blockage from being discovered in time and resulting in a large number of unqualified products. Example 3

[0049] On the basis of Example 1, considering the processing problem of the sample to be tested, in order to avoid the waste of the sample to be tested, the discharge port 83 of the grinding detector 8 of this embodiment is connected with a discharge pipe 84, and the discharge pipe 84 is connected to the discharge bin mechanism 6. Specifically, the discharge pipe 84 can be connected to the discharge bin 61 of the discharge bin mechanism 6, and then enter the equipment of the next process along the main lifting pipe 62 connected to the bottom of the discharge bin 61. It can be understood that compared with the main material entering the discharge bin mechanism 6 after grinding, the amount of the sample to be tested entering the auger box 73 during sampling can be ignored, so after the test, the sample to be tested is mixed with the main material, which has almost no effect on the overall quality of the product.
