Description

Technical Field

[0001] The invention relates to the technical field of crusher detection, in particular to a detection device for a health food powder crusher. Background Art

[0002] In the prior art, health food refers to food that contains certain ingredients, has specific health functions, and is suitable for specific groups of people to supplement the deficiencies of regular diet or adjust physiological functions. This type of food is usually rich in vitamins, minerals, dietary fiber, amino acids, probiotics, etc., and has the effect of improving human health. In order to better absorb, health food is usually crushed into powder, which can also extend its shelf life.

[0003] Chinese Patent Publication No.: CN108871898A discloses a sample pretreatment device for food testing, comprising a base, a crushing device installed on the base, a sample storage and processing device installed on the crushing device, the crushing device comprising a U-shaped support frame, a crushing plate and a lifting assembly for controlling the lifting of the crushing plate, the U-shaped support frame is vertically installed on the base, and the three side walls of the U-shaped support frame are arranged in the vertical direction, the lifting assembly is installed on the inner wall of the U-shaped support frame, and the crushing plate is installed on the top of the lifting assembly; the sample storage and processing device comprises a box body, a box cover, a sample storage bag, a baffle and a roller, the box body is installed on the top of the U-shaped support frame, the upper end of the lifting assembly passes through the box body, The crushing plate is located inside the box, the sample storage bag is detachably installed in the box and is located on the crushing plate, an annular flange is installed on the inner wall of the box and above the sample storage bag, the baffle is placed on the annular flange, and the bottom of the baffle can contact the sample storage bag, the box cover is closed on the top of the box, the roller includes a connecting rod, a roller and two handles, and two opposite sides of the box are correspondingly provided with through-channels, the connecting rod passes through the two through-channels, the roller is located inside the box, and the roller is sleeved on the outside of the connecting rod, the roller is rotatably connected to the connecting rod and contacts the baffle, and the two handles are located outside the box and are respectively connected to the two ends of the connecting rod. It can be seen from this that the sample pretreatment device for food detection has the problem that due to the high-power equipment that may exist near the crusher, electromagnetic interference will be generated when the high-power equipment is running, resulting in the transmission of the detection signal being affected, thereby causing the detection stability of the crusher to decrease. Summary of the invention

[0004] To this end, the present invention provides a detection device for a health food powder crusher, which is used to overcome the problem in the prior art that due to the presence of high-power equipment near the crusher, electromagnetic interference will be generated when the high-power equipment is running, resulting in the transmission of the detection signal being affected, thereby causing the detection stability of the crusher to decrease.

[0005] To achieve the above-mentioned purpose, the present invention provides a detection device for a health food powder crusher, comprising: a crushing module, used to crush the health food into powdered health food by the crusher, comprising a feeding unit for inputting the health food, a crushing unit connected to the feeding unit for crushing the health food, a discharging unit connected to the crushing unit for outputting the powdered health food, and a moving unit arranged under the discharging unit for controlling the crusher to move; a detection module, which is connected to the crushing module, comprising a current sensor connected to the crusher for detecting the working current of the crusher, a current sensor connected to the crusher for detecting the working current of the crusher, and a current sensor connected to the crusher for detecting the working current of the crusher. A vibration sensor for detecting the vibration intensity of the crusher, a pressure sensor connected to the crusher for detecting the pressure of the crusher, and a temperature sensor arranged inside the crusher for detecting the temperature inside the crusher; a control module, which is respectively connected to the crushing module and the detection module, and is used to determine whether the detection stability of the crusher meets the requirements according to the variance of the fluctuation amplitude of the working current of the crusher, and adjust the rotation angle of the crusher or adjust the detection frequency of the pressure sensor according to the average vibration intensity of the crusher when it does not meet the requirements, and adjust the feeding speed of the health food according to the average vibration intensity of the crusher and the temperature rise rate inside the crusher.

[0006] Furthermore, the control module obtains the working current of the crusher within several detection cycles and calculates the variance of the fluctuation amplitude of the working current of the crusher. If the variance of the fluctuation amplitude of the working current of the crusher is greater than a preset first variance, it is determined that the detection stability of the crusher does not meet the requirements.

[0007] Furthermore, when the variance of the fluctuation amplitude of the working current of the crusher is greater than the preset first variance and less than or equal to the preset second variance, the control module preliminarily determines that the detection accuracy of the crusher does not meet the requirements, and makes a secondary judgment on whether the detection accuracy of the crusher meets the requirements based on the average vibration intensity of the crusher.

[0008] Furthermore, the control module increases the rotation angle of the crusher when the variance of the fluctuation amplitude of the working current of the crusher is greater than the preset second variance; The increase range of the rotation angle of the crusher is determined by the difference between the variance of the fluctuation range of the working current of the crusher and a preset second variance.

[0009] Furthermore, the control module obtains the vibration intensity of the crusher within several detection cycles and calculates the average vibration intensity of the crusher. If the average vibration intensity of the crusher is greater than a preset first vibration intensity, it is secondary determined that the detection accuracy of the crusher does not meet the requirements.

[0010] Furthermore, when the average vibration intensity of the crusher is greater than a preset second vibration intensity, the control module preliminarily determines that the environmental stability of the crusher does not meet the requirements, and makes a secondary determination on whether the environmental stability of the crusher meets the requirements based on the temperature rise rate inside the crusher.

[0011] Further, the control module increases the detection frequency of the pressure sensor when the average vibration intensity of the crusher is greater than the preset first vibration intensity and less than or equal to the preset second vibration intensity.

[0012] Furthermore, the increase amplitude of the detection frequency of the pressure sensor is determined by the difference between the average vibration intensity of the crusher and a preset first vibration intensity.

[0013] Furthermore, the control module obtains the temperature inside the crusher within a single detection cycle and calculates the temperature increase rate inside the crusher. If the temperature increase rate inside the crusher is greater than a preset increase rate, it is secondary determined that the environmental stability of the crusher does not meet the requirements, and the feeding speed of the health food is reduced.

[0014] Furthermore, the reduction range of the feeding speed of the health food is determined by the difference between the temperature increase rate inside the crusher and a preset increase rate.

[0015] Compared with the prior art, the beneficial effect of the present invention lies in that the device of the present invention adjusts the rotation angle of the crusher according to the variance of the fluctuation amplitude of the working current of the crusher by setting a crushing module, a detection module and a control module. Since there may be high-power equipment near the crusher, electromagnetic interference will be generated when the high-power equipment is running, resulting in the transmission of the detection signal being affected, thereby causing inaccurate detection. By increasing the rotation angle of the crusher, the influence of electromagnetic interference on signal transmission is reduced. The detection frequency of the pressure sensor is adjusted according to the average vibration intensity of the crusher. Due to the long-term use of the crusher, the bolts of the internal fixed blade are loosened, resulting in increased vibration during operation, thereby causing the accuracy of detection to decrease. By increasing the detection frequency of the pressure sensor, pressure data can be obtained more frequently, so that the obtained pressure data is more accurate. The feeding speed of the health food is adjusted according to the temperature increase rate inside the crusher. Due to the long-term use, the bearing is insufficiently lubricated, resulting in increased friction between the rotating parts, thereby causing the temperature inside the crusher to rise too fast. By reducing the feeding speed of the health food, the load of the equipment can be reduced, the heat generated by friction can be reduced, the possibility of bearing wear can be reduced, and the detection stability of the crusher can be improved.

[0016] Furthermore, the device of the present invention adjusts the rotation angle of the crusher by setting a preset first variance and a preset second variance. Since there may be high-power equipment near the crusher, electromagnetic interference will be generated when the high-power equipment is running, causing the transmission of the detection signal to be affected, thereby causing inaccurate detection. By increasing the rotation angle of the crusher, the impact of electromagnetic interference on signal transmission is reduced, and the detection stability of the crusher is further improved.

[0017] Furthermore, the device of the present invention adjusts the detection frequency of the pressure sensor by setting a preset first vibration intensity and a preset second vibration intensity. Due to the long-term use of the crusher, the bolts that fix the internal blade become loose, resulting in increased vibration during operation, thereby causing the detection accuracy to decrease. By increasing the detection frequency of the pressure sensor, pressure data can be obtained more frequently, thereby making the obtained pressure data more accurate, further improving the detection stability of the crusher.

[0018] Furthermore, the device of the present invention adjusts the feeding speed of the health food by setting a preset increase rate. Due to long-term use, the lubrication of the bearings is insufficient, which leads to increased friction between the rotating parts, thereby causing the temperature inside the crusher to rise too quickly. By reducing the feeding speed of the health food, the load on the equipment can be reduced, the heat generated by friction can be reduced, the possibility of bearing wear can be reduced, and the detection stability of the crusher can be further improved.

[0024] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown in the figure, they are respectively the overall structural schematic diagram, the overall structural block diagram, the logic flow chart and the specific structural block diagram of the crushing module of the detection device for health food powder crusher according to the embodiment of the present invention. The detection device for health food powder crusher according to the present invention comprises: A crushing module, used for crushing the health food into powdered health food by a crusher, comprising a feeding unit for inputting the health food, a crushing unit connected to the feeding unit for crushing the health food, a discharging unit connected to the crushing unit for discharging the powdered health food, and a moving unit arranged under the discharging unit for controlling the movement of the crusher; a detection module connected to the crushing module, comprising a current sensor 2 connected to the crusher for detecting the working current of the crusher, a vibration sensor 7 connected to the crusher for detecting the vibration intensity of the crusher, a pressure sensor 3 connected to the crusher for detecting the pressure of the crusher, and a temperature sensor 6 arranged inside the crusher for detecting the temperature inside the crusher; A control module, which is connected to the crushing module and the detection module respectively, is used to determine whether the detection stability of the crusher meets the requirements according to the variance of the fluctuation amplitude of the working current of the crusher, and when it does not meet the requirements, adjust the rotation angle of the crusher or adjust the detection frequency of the pressure sensor 3 according to the average vibration intensity of the crusher, and adjust the feeding speed of the health food according to the average vibration intensity of the crusher and the temperature rise rate inside the crusher.

[0025] Specifically, health foods include vitamin tablets, protein blocks, and digestive enzyme tablets.

[0026] Specifically, the feeding unit includes: Feed inlet 5; The conveyor belt 4 is connected to the feeding port 5 and is used to convey the health food to the feeding port 5 .

[0027] Specifically, the crushing unit includes: A movable knife 8, which is arranged below the feed port 5 and is used to crush the health food; The screen 9 is arranged below the moving knife 8 and is used for filtering the crushed health food.

[0028] Specifically, the discharging unit is a discharging port 10 .

[0029] Specifically, the mobile unit includes: A universal wheel 1, which is arranged below the screen 9 and is used to drive the crusher to move; The motor 11 is connected to the universal wheel 1 to increase the moving power.

[0030] Specifically, the rotation angle of the crusher is the rotation angle of the feed port 5 of the crusher away from the device emitting electromagnetic interference on the horizontal plane.

[0031] In implementation, the device of the present invention adjusts the rotation angle of the crusher according to the variance of the fluctuation amplitude of the working current of the crusher by setting a crushing module, a detection module and a control module. Since there may be high-power equipment near the crusher, electromagnetic interference will be generated when the high-power equipment is running, resulting in the transmission of the detection signal being affected, thereby causing inaccurate detection. By increasing the rotation angle of the crusher, the influence of electromagnetic interference on signal transmission is reduced. The detection frequency of the pressure sensor 3 is adjusted according to the average vibration intensity of the crusher. Due to the long-term use of the crusher, the bolts of the internal fixed blade are loosened, resulting in increased vibration during operation, thereby causing the accuracy of detection to decrease. By increasing the detection frequency of the pressure sensor 3, pressure data can be obtained more frequently, so that the obtained pressure data is more accurate. The feeding speed of the health food is adjusted according to the temperature increase rate inside the crusher. Due to long-term use, the lubrication of the bearing is insufficient, resulting in increased friction between the rotating parts, thereby causing the temperature inside the crusher to rise too fast. By reducing the feeding speed of the health food, the load of the equipment can be reduced, the heat generated by friction can be reduced, the possibility of bearing wear can be reduced, and the detection stability of the crusher can be improved.

[0032] Specifically, the control module obtains the working current of the crusher within several detection cycles and calculates the variance of the fluctuation amplitude of the working current of the crusher. If the variance of the fluctuation amplitude of the working current of the crusher is greater than a preset first variance, it is determined that the detection stability of the crusher does not meet the requirements.

[0033] Specifically, when the variance of the fluctuation amplitude of the working current of the crusher is greater than the preset first variance and less than or equal to the preset second variance, the control module preliminarily determines that the detection accuracy of the crusher does not meet the requirements, and makes a secondary judgment on whether the detection accuracy of the crusher meets the requirements based on the average vibration intensity of the crusher.

[0034] It can be understood that the three intervals corresponding to the preset first variance Q1 and the preset second variance Q2 correspond to three situations respectively. The first interval is Q≤Q1, which corresponds to the situation that the detection stability of the crusher meets the requirements; the second interval is Q1<Q≤Q2, which corresponds to the situation that the bolts fixing the internal blades of the crusher become loose due to long-term use, resulting in increased vibration during operation, thereby causing the accuracy of the detection to decrease; the third interval is Q>Q2, which corresponds to the situation that there may be high-power equipment near the crusher, and electromagnetic interference will be generated when the high-power equipment is running, resulting in the transmission of the detection signal being affected, thereby causing inaccurate detection. In practice, the range of Q1 is generally selected as [9A 2 , 11A 2 ], Q2 is generally selected in the range of [11A 2 , 13A 2 ].

[0035] Preferably, the preferred embodiment of the preset first variance Q1 is 10A 2 The preferred embodiment of the preset second variance Q2 is 12A 2 .

[0036] Specifically, the variance of the fluctuation amplitude of the working current of the crusher is recorded as Q.

[0037] Specifically, the variance of the fluctuation amplitude of the working current of the crusher is the variance of the fluctuation amplitude of the working current of the crusher within several detection cycles. The calculation method of the variance of the fluctuation amplitude of the working current of the crusher is a conventional technical means well known to those skilled in the art. Therefore, the calculation process of the variance of the fluctuation amplitude of the working current of the crusher will not be repeated here.

[0038] In implementation, the device of the present invention determines the detection stability of the crusher by setting a preset first variance and a preset second variance, thereby reducing the impact of reduced detection accuracy of the crusher due to inaccurate judgment of the detection stability of the crusher, and further improving the detection stability of the crusher.

[0039] Specifically, the control module increases the rotation angle of the crusher when the variance of the fluctuation amplitude of the working current of the crusher is greater than the preset second variance; The increase range of the rotation angle of the crusher is determined by the difference between the variance of the fluctuation range of the working current of the crusher and a preset second variance.

[0040] Specifically, the calculation formula of the increased rotation angle of the crusher is: Among them, V' is the increased rotation angle of the crusher, V is the current rotation angle of the crusher, A is the minimum unit variance for adjusting the rotation angle of the crusher, and v is the rotation angle of the crusher when the variance of the fluctuation amplitude of the working current of the crusher is the minimum unit variance.

[0041] In practice, the value of A is generally 14A. 2 ~16A 2 , preferably, the preferred embodiment of A is 15A 2 .

[0042] In implementation, the optional range of the value of v is [25°, 35°]. Preferably, when the rotation angle of the crusher is less than 30°, the transmission of the detection signal may be affected. Therefore, the preferred embodiment of v is 30°.

[0043] For example, a health food powder crushing detection device is used to detect the crushing process of protein blocks, where V=25°, Q=15A 2 , we can calculate V'= =31°.

[0044] In implementation, the device of the present invention adjusts the rotation angle of the crusher by setting a preset first variance and a preset second variance. Since there may be high-power equipment near the crusher, electromagnetic interference will be generated when the high-power equipment is running, causing the transmission of the detection signal to be affected, thereby causing inaccurate detection. By increasing the rotation angle of the crusher, the impact of electromagnetic interference on signal transmission is reduced, and the detection stability of the crusher is further improved.

[0045] Specifically, the control module obtains the vibration intensity of the crusher within several detection cycles and calculates the average vibration intensity of the crusher. If the average vibration intensity of the crusher is greater than a preset first vibration intensity, the secondary determination is made that the detection accuracy of the crusher does not meet the requirements.

[0046] Specifically, when the average vibration intensity of the crusher is greater than a preset second vibration intensity, the control module preliminarily determines that the environmental stability of the crusher does not meet the requirements, and makes a secondary determination on whether the environmental stability of the crusher meets the requirements based on the temperature rise rate inside the crusher.

[0047] It can be understood that the three intervals corresponding to the preset first vibration intensity P1 and the preset second vibration intensity P2 correspond to three situations respectively. The first interval is P≤P1, which corresponds to the situation that the detection accuracy of the crusher meets the requirements; the second interval is P1<P≤P2, which corresponds to the situation that the bolts fixing the internal blades become loose due to long-term use of the crusher, resulting in increased vibration during operation, thereby causing the detection accuracy to decrease; the second interval is P>P2, which corresponds to the situation that long-term use leads to insufficient lubrication of the bearings, resulting in increased friction between rotating parts, and thus causing the temperature inside the crusher to rise too quickly. In practice, P1 is generally selected in the range of [8mm / s 2 , 10mm / s 2 ], P2 is generally selected in the range of [11mm / s 2 , 13mm / s 2 ].

[0048] Preferably, the preferred embodiment of the preset first vibration intensity P1 is 9 mm / s 2 The preferred embodiment of the preset second vibration intensity P2 is 12 mm / s 2 .

[0049] Specifically, the average vibration intensity of the crusher is denoted by P.

[0050] Specifically, the average vibration intensity of the crusher is calculated as: Among them, P is the average vibration intensity of the crusher, X a is the vibration intensity of the crusher in the ath detection cycle, n is the number of detection cycles, and n is a natural number greater than or equal to 1.

[0051] In implementation, the device of the present invention performs a secondary judgment on the detection accuracy of the crusher by setting a preset first vibration intensity and a preset second vibration intensity, thereby reducing the impact of the inaccurate secondary judgment on the detection accuracy of the crusher on the reduced detection stability of the crusher, and further improving the detection stability of the crusher.

[0052] Specifically, the control module increases the detection frequency of the pressure sensor 3 when the average vibration intensity of the crusher is greater than the preset first vibration intensity and less than or equal to the preset second vibration intensity.

[0053] Specifically, the increase range of the detection frequency of the pressure sensor 3 is determined by the difference between the average vibration intensity of the crusher and the preset first vibration intensity.

[0054] Specifically, the calculation formula of the increased detection frequency of the pressure sensor 3 is: Among them, H' is the increased detection frequency of the pressure sensor 3, H is the current detection frequency of the pressure sensor 3, B is the minimum unit vibration intensity for adjusting the detection frequency of the pressure sensor 3, and h is the detection frequency of the pressure sensor 3 when the average vibration intensity of the crusher is the minimum unit vibration intensity.

[0055] In practice, the value of B is generally taken as 13 mm / s 2 ~15m / s 2 , preferably, the preferred embodiment of B is 14mm / s 2 .

[0056] In implementation, the optional range of h is [15 Hz, 25 Hz]. Preferably, when the detection frequency of the pressure sensor 3 is less than 20 Hz, it may cause the problem of reduced detection accuracy. Therefore, the preferred embodiment of h is 20 Hz.

[0057] For example, a health food powder crushing detection device is used to detect the crushing process of protein blocks, where H=15Hz, P=16mm / s 2 , we can calculate H'= =25Hz.

[0058] In implementation, the device of the present invention adjusts the detection frequency of the pressure sensor 3 by setting a preset first vibration intensity and a preset second vibration intensity. Due to the long-term use of the crusher, the bolts that fix the internal blade become loose, resulting in increased vibration during operation, thereby causing the detection accuracy to decrease. By increasing the detection frequency of the pressure sensor 3, pressure data can be obtained more frequently, thereby making the obtained pressure data more accurate, further improving the detection stability of the crusher.

[0059] Specifically, the control module obtains the temperature inside the crusher within a single detection cycle and calculates the temperature increase rate inside the crusher. If the temperature increase rate inside the crusher is greater than the preset increase rate, it is secondary determined that the environmental stability of the crusher does not meet the requirements, and the feeding speed of the health food is reduced.

[0060] It can be understood that the two intervals corresponding to the preset increase rate Y0 correspond to two situations. The first interval is Y≤Y0, corresponding to the situation where the environmental stability of the crusher meets the requirements; the second interval is Y>Y0, corresponding to the situation where long-term use leads to insufficient lubrication of the bearings, resulting in increased friction between rotating parts, and thus causing the temperature inside the crusher to rise too quickly. In practice, Y0 is generally selected in the range of [4℃ / h, 6℃ / h].

[0061] Preferably, the preset increasing rate Y0 is 5° C. / h.

[0062] Specifically, the rate of temperature increase inside the crusher is recorded as Y.

[0063] Specifically, the temperature rise rate inside the crusher is calculated as: Among them, Y is the temperature increase rate inside the crusher, K1 is the temperature inside the crusher at the end of a single detection cycle, K2 is the temperature inside the crusher at the initial moment of a single detection cycle, and T is the duration of a single detection cycle.

[0064] In implementation, the device of the present invention performs a secondary judgment on the environmental stability of the crusher by setting a preset increase rate, thereby reducing the impact of the inaccurate secondary judgment on the environmental stability of the crusher on the detection stability of the crusher, and further improving the detection stability of the crusher.

[0065] Specifically, the reduction range of the feeding speed of the health food is determined by the difference between the temperature increase rate inside the crusher and the preset increase rate.

[0066] Specifically, the calculation formula for the reduced feeding rate of health food is: Among them, L' is the reduced feeding speed of the health food, L is the current feeding speed of the health food, C is the minimum unit increase rate for adjusting the feeding speed of the health food, and l is the feeding speed of the health food when the temperature increase rate inside the crusher is the minimum unit increase rate.

[0067] In practice, the value of C is generally 7°C / h to 9°C / h. Preferably, the preferred embodiment of C is 8°C / h.

[0068] In practice, the optional range of l is [4kg / h, 6kg / h]. Preferably, when the feeding rate of health food is greater than 5kg / h, it may cause the temperature of the inner wall of the crusher to rise too quickly. Therefore, the preferred embodiment of l is 5kg / h.

[0069] For example, a health food powder crushing detection device is used to detect the crushing process of protein blocks, where L = 6kg / h, Y = 9℃ / h, and L' = =3.5kg / h.

[0070] In practice, the device of the present invention adjusts the feeding speed of health food by setting a preset increase rate. Due to long-term use, the lubrication of the bearings is insufficient, which increases the friction between the rotating parts, thereby causing the temperature inside the crusher to rise too quickly. By reducing the feeding speed of health food, the load on the equipment can be reduced, the heat generated by friction can be reduced, the possibility of bearing wear can be reduced, and the detection stability of the crusher can be further improved.

[0071] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
