DETAILED DESCRIPTION

[0035] In order to further explain the technical scheme of the present application, specific embodiments will be described in detail below.

[0036] Please refer to Figures 1-2 The present application provides a coffee intelligent blending equipment, which comprises a mixing cylinder 1, a support 2 fixedly connected to the bottom of the mixing cylinder 1, a controller 3 installed on the right side of the support 2, a guide plate 4 installed in the middle of the support 2, a scraping strip 5 slidingly arranged inside the guide plate 4, a discharge pipe 6 arranged at the lower end of the mixing cylinder 1, a hopper assembly 7 installed on the upper end of the mixing cylinder 1, a mixing assembly 8 arranged inside the mixing cylinder 1, a screening assembly 9 installed at the inner bottom of the mixing cylinder 1, and a detection module 10 installed outside the discharge pipe 6.

[0037] The controller 3 adopts an industrial-grade ARM processor, integrates an AI algorithm acceleration chip, and is built-in with a BP neural network model with more than 100,000 training samples, which can cooperate with the detection module 10 to analyze the water content, oil content, acidity and other parameters of coffee beans within a few seconds.

[0038] Please refer to Figures 3-6 The hopper assembly 7 in the embodiment comprises a dust filtering device 71 and a hopper structure 72, the dust filtering device 71 is arranged at the upper end of the hopper structure 72, and the hopper structure 72 is arranged at the upper end of the mixing cylinder 1.

[0039] The dust filtering device 71 comprises a top cover 711, a fan 712 is installed in the middle of the upper end of the top cover 711, and a first filter screen 713 is arranged at the upper end of the fan 712. The first filter screen 713 can prevent external dust from entering. The first filter screen 713 is buckled and connected to the upper end of the top cover 711. A second filter screen 714 is arranged at the lower end of the fan 712. The second filter screen 714 can block coffee bean dust. A dust collecting cylinder 715 is screwed and connected to the lower end of the top cover 711. Gas collecting pipes 716 are installed on the outside of the lower end of the top cover 711. Connection covers 717 are installed at the bottom of the gas collecting pipes 716. The connection covers 717 are connected to the upper end of the bin structure 72.

[0040] The bin structure 72 comprises a connecting cylinder 721. The upper end of the connecting cylinder 721 is connected to the top cover 711. The lower end of the connecting cylinder 721 is connected to the mixing cylinder 1. The connecting cylinder 721 can adsorb and collect coffee bean dust inside. A butt joint plate 722 is fixedly arranged at the upper end of the connecting cylinder 721. A plurality of bins 723 are embedded on both sides of the butt joint plate 722. Flexible hoses 724 are connected to the bottom of the plurality of bins 723. First electromagnetic metering valves 725 are connected to the lower end of the plurality of flexible hoses 724. The bottom of the first electromagnetic metering valves 725 is connected to a weighing cylinder 726. A weighing platform 727 is installed at the lower end of the weighing cylinder 726. A weighing sensor 728 is connected to the bottom of the weighing platform 727. A second electromagnetic metering valve 729 is connected to the opening at the bottom of the weighing platform 727. The bottom opening of the second electromagnetic metering valve 729 extends into the inside of the mixing cylinder 1.

[0041] The number of the bins 723 arranged inside the butt joint plate 722 is not less than twelve. Feeding pipes are installed on the outside of the upper end of each bin 723. The feeding pipes can store and feed multiple types of coffee beans and satisfy the coffee blending activity.

[0042] Specifically, an operator inputs a formula through the controller 3. The system automatically retrieves successful parameters of similar formulas in a historical database to generate an initial mixing scheme. The system checks the feasibility of the formula. If the remaining amount of a bin is less than the required amount of the formula, a feeding reminder is automatically triggered. At this time, the coffee beans corresponding to the inside of the bin 723 will be discharged in the order of “low-density beans first and high-density beans last” through the first electromagnetic metering valve 725 to avoid the deposition of high-density beans affecting the weighing accuracy. The real-time feedback of the weighing platform 727 and the weighing sensor 728 is combined. The real-time weight curve is displayed on the control interface. When the preset value is reached, the first electromagnetic metering valve 725 is closed.

[0043] And by running the fan 712 set in the middle of the upper end of the top cover 711, a suction effect can be formed, so that the connecting cover 717 connected to the upper end of the hopper 723 can adsorb the dust generated by the feeding of coffee beans, so that the dust enters the dust collecting cylinder 715 along the gas collecting pipe 716, and the cooperation of the second filter screen 714 can block the dust, so that the dust can fall and collect in the dust collecting cylinder 715. In this way, the filtering and collection of coffee bean dust are achieved, and the accuracy of the sensor is not affected by the coffee bean dust. By lifting the top cover 711 and rotating the dust collecting cylinder 715, the dust collecting cylinder 715 can be quickly removed from the middle of the lower end of the top cover 711 to satisfy the quick cleaning of the collected dust.

[0044] Please refer to Figures 7-8 The mixing assembly 8 in the embodiment includes a stirring structure 81 and a vortex structure 82. The stirring structure 81 is arranged inside the mixing cylinder 1, and the vortex structure 82 is installed on the inner wall of the mixing cylinder 1. The stirring structure 81 includes a protective shell 811, which is connected to the upper end inside the mixing cylinder 1. An electric motor 812 is arranged inside the protective shell 811. The bottom output end of the electric motor 812 is connected to a first bevel gear 813. The bottom right side of the first bevel gear 813 is engaged with a second bevel gear 814. The lower end of the second bevel gear 814 is engaged with a third bevel gear 815. The third bevel gear 815 is arranged opposite to the first bevel gear 813. A inner tube 816 is vertically connected to the lower end of the first bevel gear 813. An outer tube 817 is vertically connected to the lower end of the third bevel gear 815. The inner tube 816 is vertically inserted into the inner tube 817. A first propeller 818 and a second propeller 819 are arranged at the lower ends of the inner tube 816 and the outer tube 817, respectively. The rotation speed of the first propeller 818 and the second propeller 819 is continuously adjustable between 0-300 rpm.

[0045] The vortex structure 82 includes a connecting pipe 821, which is installed on the right side of the mixing cylinder 1. The left side of the connecting pipe 821 is connected to a transmission pipe 822, which is arranged on the inner wall of the mixing cylinder 1. An airflow nozzle 823 is arranged on the inner side of the transmission pipe 822.

[0046]

[0047] The mixing stage and the mixing data are shown in the above table

[0048] The size of the first propeller 818 is smaller than that of the second propeller 819. There is a gap between the first propeller 818 and the second propeller 819. The double propellers form a three-dimensional flow field of "axial lifting + radial diffusion", which makes the coffee beans tumble and mix up and down, and circulate multiple times per second.

[0049] The eight air flow nozzles 823 are equidistantly distributed along the outer part of the transmission pipe 822, and the air flow nozzles 823 are installed at an angle of 30° and face the mixing center, that is, the air flow nozzles 823 periodically spray compressed air to form vortexes, which break the electrostatic adsorption between the particles through air flow shear force and promote the mixing of the coffee beans.

[0050] Specifically, after the coffee beans complete the metering and weighing activity, they can enter the inside of the mixing cylinder 1. At this time, by operating the motor 812, the motor 812 can rotate the first bevel gear 813 connected to the bottom output end. The rotation of the first bevel gear 813 can not only engage the second bevel gear 814, but also rotate the inner tube 816 vertically connected to the bottom. When the second bevel gear 814 rotates, it can engage and drive the third bevel gear 815 connected to the bottom. In this way, the outer tube 817 connected to the lower end of the third bevel gear 815 can rotate. In this way, the inner tube 816 and the outer tube 817 will rotate in opposite directions, and in this way, the first propeller 818 and the second propeller 819 connected to the bottom will rotate in opposite directions, forming a three-dimensional flow field of "axial lifting + radial diffusion", which makes the coffee beans roll up and down and mix. At the same time, combined with the periodic air injection effect of the air flow nozzles 823, a vortex of a certain speed can be formed to enhance the dispersion effect of the coffee bean particles, make the coffee bean dispersion more uniform, reduce the coffee bean aggregation problem, and strengthen the subsequent blending quality.

[0051] Please refer to Figure 9 The screening assembly 9 in the embodiment includes a screening plate 91, which is installed at the lower end in the mixing cylinder 1, and the middle part of the lower end of the screening plate 91 is connected to an ultrasonic vibration motor 92. The upper end of the ultrasonic vibration motor 92 is connected to a fixed bar 93, and the left and right sides of the fixed bar 93 are fixedly connected to the lower end in the mixing cylinder 1. The lower end of the mixing cylinder 1 is provided with discharge ports 94 on the left and right sides. A blocking ring 95 is movably arranged outside the mixing cylinder 1. The bottom of the blocking ring 95 is connected to the upper ends of four elastic extension rods 96, and the lower ends of the four elastic extension rods 96 are connected to a fixed ring 97, which is fixedly arranged at the lower end of the mixing cylinder 1.

[0052] The frequency of the ultrasonic vibration motor 92 is 20-40 kHz, and the vibration amplitude is 0.1-0.3 mm.

[0053] Specific, the mixed coffee beans will fall on the upper end of the screening plate 91, and the screening plate 91 can be vibrated by the ultrasonic vibration motor 92 connected at the bottom, and the vibration frequency is started every 2 minutes, so that the dropped coffee beans can be vibrated, which can not only enhance the dispersibility of the coffee beans, but also remove impurities and improve the quality of the coffee beans. The screened coffee beans will fall through the screening plate 91 into the discharge pipe 6 to discharge, and the non-compliant coffee beans or impurities will be collected in the discharge port 94 at the side of the screening plate 91. When the treatment activity is to be performed, the blocking ring 95 can be pushed down to make the blocking ring 95 cooperate with the elastic expansion rod 96 connected at the lower end of the four sides to move downward and compress. In this way, the downward movement of the blocking ring 95 can remove the blockage of the two side discharge ports 94 to quickly clean the non-compliant coffee beans or impurities. Loosening the blocking ring 95 can cooperate with the elastic expansion rod 96 on each side to rebound and automatically close the two side discharge ports 94 to ensure the stable screening activity.

[0054] Please refer to Figure 10 The detection module 10 in the embodiment includes a clamp 101 mounted on the outer side of the upper end of the discharge pipe 6. The front side of the clamp 101 is fixedly connected with a connecting block 102. The front side of the connecting block 102 is respectively mounted with a diffuse reflection probe 103 and a line array CCD detector 104, and the line array CCD detector 104 is arranged on the left and right sides of the diffuse reflection probe 103.

[0055] The diffuse reflection probe 103 and the line array CCD detector 104 are composed, and the spectral range is 900-1700nm.

[0056] Specifically, the mixed and screened coffee beans will fall from the discharge pipe 6 into the guide plate 4, and then enter the finished product bin. During the discharging process, the combination of the scanning of the diffuse reflection probe 103 and the line array CCD detector 104 and the controller 3 integrated with an AI algorithm acceleration chip and a built-in BP neural network model, i.e., the combination of the near-infrared spectrum sensor and the machine learning model, can analyze the coffee bean data and the blending situation. The blending mode is updated by detecting the data, for example, if the water content is greater than the threshold value, the precision mixing stage is automatically extended, and the air flow pressure is increased, so as to enhance the dispersion effect of the coffee bean particles, make the coffee beans evenly dispersed, reduce the coffee bean aggregation problem, and improve the coffee bean blending efficiency and quality.

[0057] The above only describes the preferred examples of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
