Description

Technical Field

[0001] The invention relates to the technical field of feeding, and in particular to an aluminum chip feeding device. Background Art

[0002] Aluminum alloy materials are widely used in modern manufacturing due to their high corrosion resistance and good thermal conductivity. As one of the common materials in the construction industry and life equipment processing field, aluminum alloy materials have good adaptability in high temperature and high heat environment, and aluminum alloy can be made into products of different shapes and structures. Aluminum alloys need to be made into aluminum ingots first, and then the aluminum ingots are extruded to form aluminum alloy products. The preparation process of aluminum ingots is usually to heat aluminum chips to form aluminum solution, and then pour the aluminum solution into the mold to cool it to form aluminum alloy ingots. Before heating, the aluminum chips need to go through a series of pre-treatment steps such as impurity removal. A large amount of aluminum chips usually need to be transported using a feeding device in the pre-treatment process.

[0003] With the advancement of science and technology and the development of the machinery industry, the production process is increasingly pursuing an automated production model, because the use of automated technology in production has greatly improved social labor productivity and enhanced human ability to transform nature. While automated high-speed production is in progress, quality improvement is also being pursued, and online testing equipment is also being paid more and more attention. Only when automated production lines are combined with automated online testing equipment can high-quality and high-speed production be achieved, achieving twice the result with half the effort.

[0004] In the existing aluminum chip feeding device, the feeding and transportation are usually carried out through a screw conveyor (auger). The transportation volume of aluminum chips is usually large, and the equipment volume is also large. When aluminum chips are stored in the screw conveyor, they cannot be discovered in time, and the resistance is too large, resulting in failure of the drive motor, affecting the transportation efficiency.

[0005] Therefore, it is urgent to provide an aluminum chip feeding device which, compared with the prior art, can automatically monitor the blockage during feeding and make automatic adjustments to ensure transportation efficiency. Summary of the invention

[0006] The invention solves the technical problems existing in the prior art and provides an aluminum chip feeding device.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0008] An aluminum chip feeding device includes a feeding component, a material transfer component and a controller. The feeding component is provided with a first feeding port and a first discharging port. The feeding component realizes feeding by setting a first motor. The material transfer component is provided with a second feeding port and a second discharging port. The feeding component is communicated with a storage bin through the first feeding port. The material transfer component is communicated with the storage bin through the second discharging port. A material transfer port is arranged at the lower wall of the feeding component near the first discharging port. A baffle plate is arranged to cover the material transfer port. The baffle plate is slidably connected to the feeding component. The material transfer port is connected to the second feeding port. A first pressure sensor is arranged on the side wall of the feeding component near the first discharging port. A vibration sensor is arranged on the first motor. The first motor, the first pressure sensor and the vibration sensor are all electrically connected to the controller;

[0009] The first pressure sensor is used to detect the discharging pressure at the first discharging port. The vibration sensor is used to detect the vibration displacement of the first motor. The controller determines by the discharging pressure and the vibration displacement, and adjusts the rotation speed of the first motor and the opening degree of the baffle plate.

[0010] Further, set the discharging pressure as P, the vibration displacement as S, set a first pressure threshold P1 and a first displacement threshold S1. When P≥P1 and S≥S1, the controller controls the rotation speed of the first motor to be reduced to 10%-20% of the original rotation speed, and at the same time controls the opening degree of the baffle plate to be 100%. When P<P1 and S≥S1, the controller controls the first motor to stop.

[0011] Furthermore, a cylinder is arranged on the side wall of the feeding component. The cylinder is used to push the first pressure sensor to move. A displacement sensor is arranged on the first pressure sensor. The displacement sensor is used to detect the displacement L of the first pressure sensor. Set a second pressure threshold P2 and a set displacement, P2<P1. When P2≤P<P1 and S<S1, the controller controls the cylinder to drive the first pressure sensor to move to the set displacement, and the first pressure sensor detects the discharging pressure P at the set displacement. 设 The controller determines the discharging pressure P at the set displacement. 设 and adjusts the rotation speed of the first motor and the opening degree of the baffle plate.

[0012] Furthermore, when P 设 ≥P1, the controller controls the rotation speed of the first motor to be reduced to 30%-40% of the original rotation speed, and at the same time controls the opening degree of the baffle plate to be 70%-80%. When P2<P 设 <P1, the controller controls the rotation speed of the first motor to be reduced to 50%-60% of the original rotation speed, and at the same time controls the opening degree of the baffle plate to be 40%-50%.

[0013] Further, a third pressure threshold P3 is set, where P2 < P3 < P1; when P3 ≤ P < P1, the controller controls the cylinder to drive the first pressure sensor to move a first set displacement; when P2 < P < P3, the controller controls the cylinder to drive the first pressure sensor to move a second set displacement, and the first set displacement is less than the second set displacement.

[0014] Further, the first set displacement is represented by the following formula:

[0015]

[0016] In the above formula, α is the correction coefficient of the cylinder, and L′ is the maximum stroke distance of the cylinder.

[0017] Further, the second set displacement is represented by the following formula:

[0018]

[0019] In the above formula, α is the correction coefficient of the cylinder, and L′ is the maximum stroke distance of the cylinder.

[0020] Further, a second pressure sensor is also provided on the side wall of the feeding assembly. The second pressure sensor is disposed near the first feeding port, and the second pressure sensor is used to detect the feeding pressure P′ at the first feeding port.

[0021] Further, when P < P2, a determination threshold P0 is set. The controller adjusts the rotation speed v of the first motor and the opening degree of the baffle by determining the relationship between the discharge pressure P, the feeding pressure P′ and the determination threshold P0. Specifically:

[0022] When P′ - P ≥ P0, the controller increases the rotation speed of the first motor to 20% - 50% of the original rotation speed and controls the opening degree of the baffle to be 0;

[0023] When P - P′ ≥ P0, the controller decreases the rotation speed of the first motor to 70% - 80% of the original rotation speed and controls the opening degree of the baffle to be 10% - 20%;

[0024] When |P′ - P| < P0, the controller controls the first motor to maintain the original rotation speed unchanged and controls the opening degree of the baffle to be 0.

[0025] Further, the material transfer assembly realizes material transfer by setting a second motor. The second motor is electrically connected to the controller, and the controller controls the rotation speed of the second motor by determining the discharge pressure P. Specifically:

[0026] When P ≥ P1,

[0027] When P2 ≤ P < P1,

[0028] When P < P2 and P - P' ≥ P0,

[0029] In the above formula, v represents the rotational speed of the first motor, and v' represents the rotational speed of the second motor.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] (1) In the present invention, the discharge pressure at the first discharge port is measured by the first pressure sensor, the vibration displacement of the first motor is measured by the vibration sensor, and the feed pressure at the first feed port is measured by the second pressure sensor. By judging the discharge pressure, feed pressure and vibration displacement, the rotational speed of the first motor and the opening degree of the baffle are adjusted in different cases, and the feeding situation is dynamically adjusted to prevent the accumulation of aluminum chips in the screw conveyor, and to avoid the failure of the driving motor caused by the blockage of aluminum chips and too large resistance. The automatic monitoring of the blockage situation during feeding is realized, and the automatic adjustment is carried out to ensure the transportation efficiency of aluminum chips during the production operation.

[0032] (2) The present invention also sets a first pressure sensor for dynamic detection, which improves the flexibility of anti-blocking detection and makes the effect of preventing blockage better. Description of the Drawings

[0039] like Figure 1 As shown, the present invention provides an aluminum chip feeding device, including a feeding component 1, a transfer component 2 and a controller, the feeding component 1 is provided with a first feed port 15 and a first discharge port 16, the transfer component 2 is provided with a second feed port 22 and a second discharge port 23, the first feed port 15 of the feeding component 1 is connected with the lower end of the storage bin 4, a transfer port 17 is provided at one end of the lower wall of the feeding component 1 close to the first discharge port 16, the transfer port 17 is connected with the second feed port 22 of the transfer component 2, the transfer port 17 is connected with the second feed port 22 through a connecting pipe 3, and the second discharge port 23 of the transfer component 2 is connected with the upper end of the side wall of the storage bin 4; the feeding component 1 and the transfer component 2 are staggered.

[0040] The feeding assembly 1 includes a trough 11, a rotating rod 12, blades 13 and a first motor 14. The first feed port 15 and the first discharge port 16 are both arranged on the trough 11. The transfer port 17 is arranged on the lower wall of the trough 11. The trough 11 is rotatably connected to the rotating rod 12. The rotating rod 12 is fixedly connected to the blade 13. The blade 13 is spirally arranged on the rotating rod 12. A first motor 14 is arranged outside the trough 11. The first motor 14 drives the rotating rod 12 to rotate. The first motor 14 is provided with a vibration sensor; the first motor 14 is started, driving the rotating rod 12 to rotate, thereby driving the blade 13 to rotate. The aluminum chips are transported during the rotation of the blade 13. The feeding assembly 1 transports the aluminum chips in the storage bin 4 from the first feed port 15 to the second discharge port 23, and the aluminum chips are transported to the next working bin through the second discharge port 23.

[0041] The material transfer component 2 is also composed of a material trough, a rotating rod, and blades. A second motor 21 is provided outside the material trough of the material transfer component 2. The second motor 21 drives the rotating rod of the material transfer component 2 to rotate, and the second motor 21 drives the blades provided in the material transfer component 2 to rotate. The material transfer component 2 is used to transport excess aluminum chips inside the feeding component 1 back to the storage bin 4 to prevent the feeding component 1 from being blocked.

[0042] A baffle plate 18 is covered at the material transfer port 17 provided in the feeding assembly 1. The baffle plate 18 is slidably connected to the lower wall of the material trough 11 of the feeding assembly 1. The baffle plate 18 is opened and closed by means of rack and gear transmission, that is, the rack is fixedly connected to the baffle plate 18, the rack meshes with the gear, and the gear is driven by a motor.

[0043] As Figure 2 、 Figure 3 shown, a groove 19 is provided on one side wall of the material trough 11 of the feeding assembly 1. The groove 19 is arranged close to the first discharge port 16. A cylinder 110 is fixedly connected inside the first groove 19. The output end of the cylinder 110 is fixedly connected to a first pressure sensor 111. A baffle member 112 is slidably connected inside the groove 19. The baffle member 112 has a hollow structure inside. The cross-sectional shape of the baffle member 112 is the same as the cross-sectional shape of the groove 19. The baffle member 112 cannot completely slide out of the groove 19. One set of opposite side walls of the baffle member 112 is open. A first pressure sensor 111 is fixedly connected at the opening on one side of the baffle member 112.

The cylinder 110 drives the first pressure sensor 111 to extend and retract from the groove 19. After the first pressure sensor 111 extends out of the groove 19, the baffle member 112 can block the aluminum chips in the feeding assembly 1 to prevent the aluminum chips from entering the inside of the groove 19. A second pressure sensor is also provided on the side wall of the feeding assembly 1 close to the first feed port 15.

[0044] The first motor 14, the second motor 21, the first pressure sensor 111, the second pressure sensor and the vibration sensor are all electrically connected to the controller.

[0045] The first pressure sensor 111 is used to detect the discharge pressure P at the first discharge port 16, and the second pressure sensor is used to detect the feed pressure P' at the first feed port 15; the vibration sensor is used to detect the vibration displacement S of the first motor 14. The controller determines by judging the discharge pressure P, the feed pressure P', and the vibration displacement S, and adjusts the rotation speed v of the first motor 14 and the opening degree of the baffle plate 18. Specifically:

[0046] Set a first pressure threshold P1 and a first displacement threshold S1; when P≥P1 and S≥S1, the controller controls the rotation speed of the first motor 14 to be reduced to 10%-20% of the original rotation speed, and at the same time controls the opening degree of the baffle plate 18 to be 100%; when P<P1 and S≥S1, the controller controls the first motor 14 to stop.

[0047] A displacement sensor is arranged on the first pressure sensor 111. The displacement sensor is used to detect the displacement L of the first pressure sensor 111. A second pressure threshold P2 is set, where P2 < P1. When P2 ≤ P < P1 and S < S1, the controller controls the cylinder 110 to drive the first pressure sensor 111 to move a set displacement, and the first pressure sensor 111 detects the discharge pressure P at the set displacement. 设 The controller determines the discharge pressure at the set displacement, so as to adjust the rotation speed v of the first motor 14 and the opening degree of the baffle plate 18.

[0048] When P 设 ≥ P1, the controller controls the rotation speed of the first motor 14 to be reduced to 30% - 40% of the original rotation speed, and at the same time controls the opening degree of the baffle plate 18 to be 70% - 80%; when P2 < P 设 < P1, the controller controls the rotation speed of the first motor 14 to be reduced to 50% - 60% of the original rotation speed, and at the same time controls the opening degree of the baffle plate 18 to be 40 - 50%.

[0049] A third pressure threshold P3 is set, where P2 < P3 < P1; when P3 ≤ P < P1, the controller controls the cylinder 110 to drive the first pressure sensor 111 to move a first set displacement; when P2 < P < P3, the controller controls the cylinder 110 to drive the first pressure sensor 111 to move a second set displacement, and the first set displacement is less than the second set displacement.

[0050] The first set displacement is expressed by the following formula:

[0051]

[0052] In the above formula, α is the correction coefficient of the cylinder 110, and L′ is the maximum stroke distance of the cylinder 110.

[0053] The second set displacement is expressed by the following formula:

[0054]

[0055] When P < P2, a determination threshold P0 is set. The controller adjusts the rotation speed v of the first motor 14 and the opening degree of the baffle plate 18 by determining the relationship between the discharge pressure P, the feed pressure P′ and the determination threshold P0. Specifically:

[0056] When P′ - P ≥ P0, the controller increases the rotation speed of the first motor 14 to 20% - 50% of the original rotation speed and controls the opening degree of the baffle plate 18 to be 0;

[0057] When P - P′ ≥ P0, the controller decreases the rotation speed of the first motor 14 to 70% - 80% of the original rotation speed and controls the opening degree of the baffle plate 18 to be 10% - 20%;

[0058] When |P′ - P| < P0, the controller controls the first motor 14 to maintain its original rotational speed and controls the opening degree of the material baffle 18 to be 0.

[0059] The controller determines the rotational speed v′ of the second motor 21 by judging the discharge pressure P, specifically as follows:

[0060] When P ≥ P1,

[0061] When P2 ≤ P < P1,

[0062] When P < P2 and P - P′ ≥ P0,

[0063] Compared with the existing aluminum chip feeding device, the present invention measures the discharge pressure of the first discharge port 16 through the first pressure sensor 111, the vibration displacement of the first motor 14 through the vibration sensor, and the feeding pressure at the first feeding port 15 through the second pressure sensor. By judging the discharge pressure, feeding pressure and vibration displacement, it regulates the rotational speed of the first motor 14 and the opening degree of the material baffle 18 in different cases, dynamically adjusts the feeding situation, prevents the occurrence of material storage of aluminum chips in the screw conveyor, and avoids the failure of the drive motor caused by aluminum chip blockage and too large resistance, ensuring the transportation efficiency of aluminum chips during the production operation; at the same time, the first pressure sensor 111 is also set to perform dynamic detection, improving the flexibility of anti-blockage detection and making the effect of preventing blockage better.
