[0021] Titanium and titanium alloy chip crusher automatic feeding method embodiment: The automatic feeding method of the titanium and titanium alloy chip crusher of the present invention is applied to the automatic feeding device of the titanium and titanium alloy chip crusher; specifically, the specific structure of the automatic feeding device of the titanium and titanium alloy chip crusher is as follows: like Figure 1 , Figure 2As shown, the automatic feeding device of the titanium and titanium alloy chip crusher includes a lifting and loading component 1, an aggregate component 2, and a vibrating feeding component 3. The lifting and loading component 1 is arranged on the side of the feed port 21 of the aggregate component 2, and the vibrating feeding component 3 is arranged below the discharge port 22 of the aggregate component 2. The feeding end of the vibrating feeding component 3 is used to be arranged above the feed port 4 of the crusher. A discharge baffle is provided at the discharge port 22 to control the flow of chips. When in use, it is necessary to start the crusher first, and then start the vibrating feeding device; wherein, for the feeding of the aggregate component 2, the lifting and loading component 1 can be performed during the feeding process or before the feeding.

[0022] like Figure 5-Figure 9 As shown, the above-mentioned lifting and loading assembly 1 includes a lifting frame 11, an L-shaped material box placement platform 12 and a driving mechanism 13. The driving mechanism 13 is arranged on the lifting frame 11, and the driving mechanism 13 is connected to the L-shaped material box placement platform 12, and the L-shaped material box placement platform 12 is used to place titanium and titanium alloy chip boxes. Among them, the lifting frame 11 is welded with high-quality structural steel, which is responsible for the support and guiding function of the entire lifting and loading assembly 1. The chip box is placed on the L-shaped material box placement platform 12, and the driving mechanism 13 drives the L-shaped material box placement platform 12 to rise, and by flipping, the chips on the L-shaped material box placement platform 12 are poured into the silo 23 of the collection assembly 2.

[0023] In order to realize the flipping of the L-shaped material box placement platform 12 of the lifting and loading assembly 1, specifically, the first sliding groove 111 and the second sliding groove 112 are provided on both sides of the lifting frame 11, the first sliding groove 111 is a vertical groove, the second sliding groove 112 is an inverted L-shaped groove, and the upper end of the second sliding groove 112 is arranged lower than the first sliding groove 111; the upper guide wheel 121 and the lower guide wheel 122 are provided on both sides of the above-mentioned L-shaped material box placement platform 12, the above-mentioned upper guide wheel 121 cooperates with the second sliding groove 112, and the above-mentioned lower guide wheel 122 cooperates with the first sliding groove 111, so that the L-shaped material box placement platform 12 flips around the upper guide wheel 121 at the upper end of the lifting frame 11; the upper guide wheel 121 and the lower guide wheel 122 are arranged on the side of the L-shaped material box placement platform 12 through the transition plate 123. That is to say, when the upper guide wheel 121 extends horizontally with the upper end of the L-shaped material box placement platform 12 at the turning point of the inverted L-shaped groove, the lower guide wheel 122 continues to rise with the lower end of the L-shaped material box placement platform 12, thereby realizing the tilting and flipping of the L-shaped material box placement platform 12, so that the chips in the chip box tilt downward from the upper opening and enter the silo 23 of the aggregate assembly 2.

[0024] In order to ensure the safety of the material collection assembly 2, a stopper 124 is provided on the L-shaped material box placement platform 12 to prevent the scrap material box from falling into the material collection assembly 2 when it is turned over. Fig. 9 In addition, the other figures do not show the shift lever 124.

[0025] Specifically, the driving mechanism 13 is connected to the lower guide wheel 122. In order to ensure the smooth lifting of the L-shaped material box placement platform 12, the driving mechanism 13 includes a driving motor 131, a reducer 132, a driving rod 133, a chain 134, a driving wheel 135 arranged on both sides of the lower end of the lifting frame 11, and a driven wheel 136 arranged on both sides of the upper end of the lifting frame 11. Among them, the driving motor 131 drives the driving rod 133 through the reducer 132, and both ends of the driving rod 133 are connected to the driving wheel 135, and the driving wheel 135 and the driven wheel 136 are both meshed with the chain 134 for transmission; the chain 134 is fixedly connected to the lower guide wheel 122. That is, in this embodiment, the drive motor 131 adopts a fixed-frequency motor with a motor power of 2.2kw, a rated voltage of 380V, and a motor power frequency of 50Hz; the chip box adopts a standard 1210 box with a size of 1200mm×1000mm×760mm.

[0026] In order to extend the service life of the lifting and loading assembly 1, a tensioning mechanism 14 is further provided at the upper end of the lifting frame 11, and the tensioning mechanism 14 is connected to the driven wheel 136 and is used to adjust the tension of the chain 134. The tensioning mechanism 14 can reduce the vibration and noise caused by the looseness or over-tightness of the chain 134, thereby reducing the loss of the lifting and loading assembly 1 during use.

[0027] Specifically, Figure 1 , Figure 2 As shown, the aggregate assembly 2 includes a silo 23, an internal staircase, an external maintenance platform 27 and a wall vibrator. The volume of the silo 23 is about 20m³, and the thickness of the silo wall is about 4mm. The vibration force range of the wall vibrator is 0-5kN. The upper part of the above-mentioned silo 23 is a quadrangular prism, and the lower part shrinks to a cone, and a discharge port 22 is provided at the bottom; the front plate 24 of the above-mentioned cone close to the vibrating feeding assembly 3 is a vertical plate; the angle between the rear plate of the above-mentioned cone and the horizontal plane is smaller than the angle between the two side plates 25 of the cone and the horizontal plane. By setting this angle, it is ensured that the chips can flow to the trough 31 more evenly, and it is avoided that the chips from multiple directions flow into the trough 31 quickly, causing the trough 31 to bear excessive local pressure, affecting the feeding effect of the vibrating feeding assembly 3.

[0028] Specifically, Figure 3 , Figure 4As shown, the vibrating feeding assembly 3 includes a trough 31, a force transmission box 32 disposed below the trough 31, and a vibration motor 33 connected to the force transmission box 32. A lower support 34 and an upper support 36 are disposed below one end of the trough 31 close to the discharge port 22, and a shock-absorbing spring 35 is disposed between the upper support 36 and the lower support 34; a suspension device 37 is connected above the other end of the trough 31 through a vibration isolation spring 38; the suspension device 37 changes the inclination angle of the trough 31 by loosening and tightening. By arranging the shock-absorbing spring 35 below the trough 31 and the vibration isolation spring 38 above the other end of the trough 31, the impact and vibration of the vibration motor 33 on the trough 31 when it is working can be reduced; the use of the shock-absorbing spring 35 and the vibration isolation spring 38 can reduce the direct contact between the trough 31 and the supporting structure, thereby reducing wear and extending the service life of the trough 31. The other end of the suspension device 37 can be set up to make the space below the discharge trough 31 convenient to be set up above the crusher feeding port 4, saving space. In addition, the other end of the suspension device 37 can be connected to the side of the aggregate assembly 2 or to the roof of the factory building, and the setting is selected according to the actual situation.

[0029] The automatic feeding method of titanium and titanium alloy chip crusher includes the following steps: Step 1: Obtain the capacity of the crusher and the target feeding time input by the user, and determine the target feeding speed of the vibration feeding assembly 3. Generally speaking, the product of the target feeding speed and the target feeding time is less than the capacity of the crusher.

[0030] Step 2: Use the target feeding speed as the input of the trained feeding parameter calculation model, and output the corresponding target tilt angle and amplitude of the trough 31 , the target unloading speed of the silo 23 , and the target frequency of the vibration motor 33 .

[0031] The training process of the feeding parameter calculation model is as follows: obtaining the historical feeding speed, the inclination angle of the trough 31, the discharge speed of the silo 23, the frequency and amplitude data of the vibration motor 33, and pre-processing the obtained data before inputting them into the feeding parameter calculation model; the feeding parameter calculation model takes the maximum feeding speed as the goal, and takes the frequency range of the vibration motor 33 of 0 to 50 Hz, the amplitude range of 0 to 4.5 mm, the inclination angle range of 10° to 30°, and the discharge speed range of 150 kg / h to 300 kg / h as constraints, and trains to obtain the trained feeding parameter calculation model.

[0032] In order to ensure the accuracy of the trained model, the preprocessing includes removing outliers, filling missing values ​​and normalizing data.

[0033] In order to better solve the nonlinear problem, the feeding parameter calculation model is constructed using a hybrid particle swarm algorithm (PSOMA). The goal of this problem is to maximize the feeding speed, that is, the feeding speed is the dependent variable, and the inclination angle, the frequency and amplitude of the vibration motor 33, and the unloading speed are independent variables. As the unloading speed increases, the corresponding feeding speed will increase, but when the unloading speed is higher, the unloading port 22 will cause the accumulation of scraps, and the corresponding feeding speed will decrease; these influencing factors can be recorded in the historical data, so the corresponding situation of each dependent variable is calculated through the trained feeding parameter calculation model.

[0034] The model training process is as follows: initialize the position and speed of the particle group, calculate the fitness value, update the speed and position of the particle, apply the constraints, repeat the above process and update the global optimal solution at the same time, until the maximum number of iterations is met, and output the global optimal solution, which corresponds to the best combination of the frequency, amplitude, tilt angle and discharge speed of the vibration motor 33. Specifically, the position corresponds to the parameters of the vibration feeding component 3, which include the tilt angle, the frequency and amplitude of the vibration motor 33, and the discharge speed, etc.; the speed represents the rate of change of these parameters. The fitness value, i.e., the feeding speed, is calculated for each particle; this is obtained by inputting the position parameters of the particle into the objective function. The speed and position of each particle are updated according to the individual historical best position, the global best position, and the current speed of the particle. It is also necessary to ensure that the updated position meets the constraints of the frequency range of the vibration motor 33 of 0 to 50 Hz, the amplitude range of 0 to 4.5 mm, the tilt angle range of 10° to 30°, and the discharge speed range of 150 kg / h to 300 kg / h. After multiple iterations, the global optimal solution is output, that is, the optimal combination of the frequency, amplitude, inclination angle and discharge speed of the vibration motor 33 is obtained to achieve the maximum feeding speed.

[0035] The objective function expression of the feeding parameter calculation model is:

[0036] in, is the parameter vector, , is the tilt angle, , is the frequency of the vibration motor 33, , is the amplitude of the vibration motor 33, , is the unloading speed, , is the feeding speed, To maximize operation.

[0037] Step 3: Control the vibration motor 33 and the discharge baffle to close according to the target feeding time, adjust the trough 31 according to the target inclination angle, control the vibration motor 33 according to the target frequency and amplitude of the vibration motor 33, and control the wall vibrator according to the target discharge speed to ensure the maximum feeding speed.

[0038] The process of controlling the wall vibrator according to the target unloading speed is as follows: obtaining the current unloading speed, and when the unloading speed is less than the target unloading speed, starting the wall vibrator; when the unloading speed is greater than or equal to the target unloading speed, controlling the wall vibrator to be turned off.

[0039] This method ensures the crushing efficiency and crushing effect of the crusher by controlling the feeding speed.
