Description

Technical Field

[0001] The invention relates to the technical field of aluminum material smelting, and in particular to a long-distance aluminum material feeding device capable of automatically recovering falling materials. Background Art

[0002] Aluminum product manufacturers usually process aluminum granules into a smelting furnace for smelting and then process them into corresponding aluminum products. Since the smelting furnace is relatively tall and the aluminum materials are usually stored far away from the smelting furnace, a long-distance aluminum material feeding device is required to transport the aluminum materials to the feeding port on the top of the smelting furnace and feed them into the smelting furnace for smelting. The long-distance aluminum material feeding device includes a primary conveyor belt and a secondary conveyor belt located in front of the primary conveyor belt. The primary and secondary conveyor belts are arranged to be inclined (high in front and low in the back), and the rear end of the secondary conveyor belt is located below the front end of the primary conveyor belt; the long-distance aluminum material feeding device also includes a driving mechanism, which drives the primary and secondary conveyor belts. The operator puts the aluminum material on the rear end of the primary conveyor belt, and the driving mechanism drives the primary and secondary conveyor belts to rotate. Driven by the primary conveyor belt, the aluminum material moves forward from the rear end of the primary conveyor belt to the front end of the primary conveyor belt, and then falls to the rear end of the secondary conveyor belt. Then, driven by the secondary conveyor belt, it moves forward from the rear end of the secondary conveyor belt to the front end of the secondary conveyor belt. The front end of the secondary conveyor belt is located above the loading port on the top of the smelting furnace. The aluminum material falls from the front end of the secondary conveyor belt and falls into the smelting furnace through the loading port to complete the loading. Since different aluminum products require different amounts of aluminum material, it is necessary to determine the target amount of aluminum material required for each smelting according to the aluminum products to be manufactured. The operator puts the target amount of aluminum material into the rear end of the primary conveyor belt of the long-distance aluminum material feeding device in many times, and lets the primary and secondary conveyor belts convey the aluminum material to the loading port of the smelting furnace and put it into the smelting furnace. Since the primary and secondary conveyor belts are inclined, during the loading process, part of the aluminum material may roll to the sides of the conveyor belt and fall off, resulting in the actual amount of aluminum material put into the melting furnace (i.e. the actual material amount) being less than the amount of aluminum material put in by the operator. Summary of the invention

[0003] The purpose of the present invention is to provide a long-distance aluminum material feeding device which can automatically recover the fallen materials. Even if the aluminum material falls from the conveyor belt during the feeding process, the fallen aluminum material can continue to be conveyed to the smelting furnace, so that the actual material amount is the amount of aluminum material put in by the operator.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a long-distance aluminum material loading device that can automatically recover the blanking material, comprising a primary conveyor belt and a secondary conveyor belt located in front of the primary conveyor belt, the primary and secondary conveyor belts are both high in the front and low in the back, and the rear end of the secondary conveyor belt receives the aluminum material transmitted from the front end of the primary conveyor belt; comprising a primary driving mechanism and a secondary driving mechanism, which respectively drive the primary and secondary conveyor belts to rotate and convey the aluminum material; blanking material recovery mechanisms are respectively arranged on both sides of the primary and secondary conveyor belts along the direction of the conveyor belts, and the blanking material recovery mechanism is provided with a receiving plate next to the conveyor belt that is lower than the conveying surface of the conveyor belt to receive the blanking material; the blanking material recovery mechanism also includes a vertical driving device, which drives the receiving plate to be lifted until the receiving plate is flush with the corresponding conveying surface of the conveyor belt, and the blanking material recovery mechanism is provided with a pushing plate to push the blanking material received on the receiving plate back to the corresponding conveyor belt.

[0005] Furthermore, the pushing plate is arranged on the material receiving plate, and the vertical driving device drives the material receiving plate to lift the pushing plate together.

[0006] Furthermore, the blanking recovery mechanism comprises a transverse driving device, which drives the pushing plate to push the blanking on the receiving plate transversely back to the conveyor belt.

[0007] Furthermore, a plurality of first anti-slip plates are provided on the surface of the primary conveyor belt to prevent the aluminum material from sliding backwards, and a plurality of second anti-slip plates are provided on the surface of the secondary conveyor belt to prevent the aluminum material from sliding backwards.

[0008] Furthermore, the plurality of first anti-slip sheets and the plurality of second anti-slip sheets are evenly spaced and arranged.

[0009] Furthermore, a controller is included, and a weight sensor is provided in the area between every two adjacent second anti-slip plates of the secondary conveyor belt, and each weight sensor is electrically connected to the controller.

[0010] Furthermore, a bottom baffle is provided at the rear end of the receiving plate to prevent the falling material on the receiving plate from sliding off.

[0011] Furthermore, the pushing plate is arranged on the side edge of the receiving plate away from the corresponding conveyor belt, and also serves as a side baffle to prevent the falling materials on the receiving plate from sliding off.

[0012] Furthermore, the surfaces of the primary conveyor belt and the secondary conveyor belt are covered with an oil and water absorbing layer for absorbing grease and moisture on the surface of the aluminum material.

[0013] Furthermore, the oil and water absorbing layer can be peeled off and pasted to cover the surface of the conveyor belt.

[0014] The present invention is provided with a material recovery mechanism on both sides of the primary and secondary conveyor belts, respectively. Even if aluminum material falls from the conveyor belt during the loading process, the receiving plate of the material recovery mechanism can receive the aluminum material that falls from the conveyor belt, and then the pushing plate can push the falling material (i.e. the falling aluminum material) on the receiving plate back to the conveyor belt to continue to be conveyed to the smelting furnace. In this way, the actual material amount will not be reduced due to part of the aluminum material falling from the conveyor belt during the loading process, ensuring that the actual material amount is the amount of aluminum material put in by the operator. The present invention sets the receiving plate to be lower than the conveying surface of the conveyor belt, and only drives the receiving plate to be raised to be flush with the conveying surface of the conveyor belt when it is necessary to recover the falling material, rather than directly setting it to be flush with the conveying surface of the conveyor belt. If the receiving plate is directly set to be flush with the conveying surface of the conveyor belt, the aluminum material may fall back into the gap between the receiving plate and the rotating part where the conveying surface of the conveyor belt is located, which may jam the conveyor belt. The present invention arranges the material receiving plate to be lower than the conveying surface of the conveyor belt, so that the aluminum material will not be stuck between the rotating part where the conveying surface of the conveyor belt is located and the material receiving plate, thereby preventing the conveyor belt from being stuck.

[0018] The present invention is further described in detail below in conjunction with specific implementation methods.

[0019] The long distance aluminum material feeding device provided in this embodiment is as follows Figure 1As shown, it includes a primary conveyor belt 1 and a secondary conveyor belt 2 located in front of the primary conveyor belt. Both the primary and secondary conveyor belts 1 and 2 are higher in the front and lower in the back, and the rear end of the secondary conveyor belt is located below the front end of the primary conveyor belt. The aluminum material feeding device includes a primary drive motor 10 and a secondary drive motor 20 as a primary drive mechanism and a secondary drive mechanism respectively. The primary drive motor drives the primary conveyor belt 1 to rotate, and the secondary drive motor drives the secondary conveyor belt 2 to rotate. The front end of the secondary conveyor belt 2 is arranged just above the feeding port on the top of the smelting furnace (not shown). When it is necessary to put aluminum materials into the smelting furnace for smelting, the operator first starts the primary drive motor 10 and the secondary drive motor 20 to drive the primary and secondary conveyor belts 1 and 2 to rotate respectively, and then the operator puts the aluminum materials to be smelted at the rear end of the primary conveyor belt 1. Driven by the primary conveyor belt 1, the aluminum materials move forward from the rear end of the primary conveyor belt 1 to the front end of the primary conveyor belt 1, and then fall to the rear end of the secondary conveyor belt 2, and then driven by the secondary conveyor belt 2, the aluminum materials move forward from the rear end of the secondary conveyor belt 2 to the front end of the secondary conveyor belt 2, and then fall from the front end of the secondary conveyor belt 2 and fall into the smelting furnace through the loading port of the smelting furnace. Since the amount of aluminum materials to be smelted at one time is usually relatively large, it is difficult to put all the aluminum materials to be smelted at the rear end of the primary conveyor belt 1 at one time. It is necessary to continuously put the target amount of aluminum materials to be smelted at the rear end of the primary conveyor belt 1 in small amounts and multiple times so that the primary and secondary conveyor belts can convey the aluminum materials to the loading port of the smelting furnace and put them into the smelting furnace.

[0020] Since the primary and secondary conveyor belts 1 and 2 are inclined, during the process of conveying aluminum materials, part of the aluminum materials carried on the conveyor belts may move relatively due to gravity. On the one hand, a large amount of aluminum materials may slide and accumulate at a certain position of the conveyor belt, which may over-press the conveyor belt and cause the conveyor belt to stop rotating. On the other hand, part of the aluminum materials may roll to the sides of the conveyor belt and fall. Figure 1As shown, the surface of the primary conveyor belt 1 and the surface of the secondary conveyor belt 2 are respectively provided with a plurality of first anti-slip sheets 11 and a plurality of second anti-slip sheets 21 arranged evenly at intervals. In the process of conveying aluminum materials, the aluminum materials can be prevented from sliding backwards, and a large amount of aluminum materials can be prevented from sliding to the same position on the conveyor belt. In this way, a large amount of aluminum materials can be avoided from accumulating at a certain position of the conveyor belt, and the incidence of aluminum materials falling off the conveyor belt can be reduced. On the other hand, the long-distance aluminum material feeding device of this embodiment is respectively provided with a blanking recovery mechanism 3 on the left and right sides of the primary and secondary conveyor belts 1 and 2 along the direction of the conveyor belt, and there are a total of four blanking recovery mechanisms 3. Each blanking recovery mechanism 3 is provided with a receiving plate 31 lower than the conveying surface of the conveyor belt next to the conveyor belt, and the length direction of the receiving plate 31 is consistent with the direction of the conveyor belt. The receiving plates 31 of the blanking recovery mechanisms on the left and right sides of the primary and secondary conveyor belts 1 and 2 respectively receive the aluminum materials falling from the left and right sides of the primary and secondary conveyor belts. A bottom baffle 35 is provided at the rear end of the receiving plate 31 to prevent the blanking on the receiving plate 31 from sliding off. Each material recovery mechanism 3 is provided with a push plate 32 on the receiving plate 31. The push plate 32 is provided on the side edge of the receiving plate 31 away from the corresponding conveyor belt and also serves as a side baffle to prevent the material on the receiving plate 31 from sliding off. The material recovery mechanism 3 also includes a vertical motor 33 (i.e., a vertical drive device), such as Figure 2 As shown, the vertical motor 33 drives the receiving plate 31 to drive the pushing plate 32 to rise together until the receiving plate 31 is flush with the corresponding conveyor belt conveying surface. Taking the blanking recovery mechanism 3 on the right side of the primary conveyor belt 1 as an example, the vertical motor 33 drives the receiving plate 31 to drive the pushing plate 32 to rise together until the receiving plate 31 is flush with the conveyor belt conveying surface. The blanking recovery mechanism 3 includes a horizontal motor 34 (i.e., a horizontal driving device), as shown in FIG. Figure 3 As shown, the transverse motor 34 drives the push plate 32 to move from the side edge of the receiving plate 31 away from the conveyor belt to the side edge of the receiving plate 31 flush with the conveying surface of the conveyor belt, so as to push the blanks on the receiving plate 31 back to the conveyor belt laterally. After the blanks are pushed back to the conveyor belt, the vertical motor 33 drives the receiving plate 31 to drive the push plate 32 to move down and return to the initial position. At the same time, the transverse motor 34 drives the push plate 32 to return laterally to the side edge of the receiving plate 31 away from the conveyor belt. In this embodiment, during the loading process, the blank recovery mechanism 3 automatically lifts according to the above process and pushes the blanks back to the conveyor belt. Preferably, a pressure sensor is provided on the receiving plate 31 of the blank recovery mechanism 3 to detect whether there is blanks on the receiving plate 31. If the pressure sensor detects that there is blanks on the receiving plate 31, the material is lifted and pushed according to the above process, otherwise it is not lifted and pushed.

[0021] The present invention is provided with a material recovery mechanism 3 on both sides of the primary and secondary conveyor belts 1 and 2, respectively. Even if aluminum material falls from the conveyor belts 1 and 2 during the loading process, the material receiving plate 31 of the material recovery mechanism 3 can receive the aluminum material falling from the conveyor belt, and then the material pushing plate 32 can push the falling material (i.e. the falling aluminum material) on the material receiving plate 31 back to the conveyor belt to continue to be transmitted to the smelting furnace. In this way, the actual material amount will not be reduced due to the falling of part of the aluminum material from the conveyor belt during the loading process, ensuring that the actual material amount is the amount of aluminum material put in by the operator. The present invention sets the material receiving plate 31 to be lower than the conveying surface of the conveyor belt, and only drives the material receiving plate 31 to be raised to be flush with the conveying surface of the conveyor belt when it is necessary to recover the falling material, rather than directly setting it to be flush with the conveying surface of the conveyor belt. If the material receiving plate 31 is directly set to be flush with the conveying surface of the conveyor belt, the aluminum material may fall back into the gap between the material receiving plate 31 and the rotating part where the conveying surface of the conveyor belt is located, which may jam the conveyor belt. In the present invention, the receiving plate 31 is arranged to be lower than the conveying surface of the conveyor belt, so that the aluminum material will not be stuck between the rotating part where the conveying surface of the conveyor belt is located and the receiving plate, thereby preventing the conveyor belt from being stuck.

[0022] If there are grease and water stains on the surface of the aluminum material, it will affect the smelting effect. Therefore, the long-distance aluminum material feeding device of this embodiment is covered with an oil-absorbing and water-absorbing layer (not shown) on the surface of the primary conveyor belt 1 and the surface of the secondary conveyor belt 2 to absorb grease and water on the surface of the aluminum material. The oil-absorbing and water-absorbing layer can be torn off and pasted on the surface of the conveyor belt. In this way, during the conveying process of the aluminum material, the grease and water stains on its surface will be absorbed by the oil-absorbing and water-absorbing layer on the surface of the conveyor belt, so that the influence of the grease and water stains on the surface of the aluminum material on the smelting effect can be reduced. After the oil-absorbing and water-absorbing layer has been used for a period of time, the operator can tear off the old oil-absorbing and water-absorbing layer on the conveyor belt and replace it with a new oil-absorbing and water-absorbing layer to ensure that the grease and water stains on the surface of the aluminum material can be better absorbed. Since a plurality of first anti-slip sheets 11 and a plurality of second anti-slip sheets 21 are arranged at intervals on the conveyor belts 1 and 2, and the size of the oil-absorbing and water-absorbing layer is designed to be the size of the intervals formed by the anti-slip sheets 11 and 21, it is necessary to paste and cover the oil-absorbing and water-absorbing layers in the intervals formed by the anti-slip sheets 11 and 21, that is, a plurality of oil-absorbing and water-absorbing layers need to be pasted on the conveyor belt, and the number of pastings is relatively large. Accordingly, if the oil-absorbing and water-absorbing layers need to be torn off and replaced, multiple sheets of the oil-absorbing and water-absorbing layers have to be torn off. Preferably, the oil-absorbing and water-absorbing layer is changed to a whole sheet, which can cover the entire surface of the conveyor belt 1, 2 and all the first anti-slip sheets 11 and the surfaces of the plurality of second anti-slip sheets 21 on the conveyor belt 1, 2. Specifically, after the oil-absorbing and water-absorbing layer is pasted to cover the interval of the conveyor belt formed by a pair of anti-slip sheets (two adjacent anti-slip sheets), it closely adheres to the surface of one of the anti-slip sheets in the pair of anti-slip sheets and crosses to the interval of the conveyor belt formed by the next pair of anti-slip sheets, pasting and covering the interval, and then closely adheres to the surface of one of the anti-slip sheets in the pair of anti-slip sheets and crosses to the interval of the conveyor belt formed by the next pair of anti-slip sheets, pasting and covering the interval, and so on, until the entire conveyor belt surface and all the anti-slip sheet surfaces on the conveyor belt are covered. The advantages of this are: first, the oil-absorbing and water-absorbing layer on the entire conveyor belt can be torn off at one time; second, if the aluminum material stays on the first anti-slip sheet 11 and the plurality of second anti-slip sheets 21, the oil-absorbing and water-absorbing layer on the surface of the first anti-slip sheet 11 and the plurality of second anti-slip sheets 21 can also absorb the grease and water stains on its surface.

[0023] The aluminum required for each smelting is put into the long-distance aluminum material feeding device by the operator for feeding. The operator may make human errors, resulting in the amount of aluminum put into the long-distance aluminum material feeding device may be wrong, which may be more than the target amount or less than the target amount. Therefore, the long-distance aluminum material feeding device of this embodiment includes a controller, and the secondary conveyor belt is provided with a weight sensor in the area between each two adjacent second anti-slip plates 21, and each weight sensor is electrically connected to the controller. The controller monitors the weight of the aluminum material actually put into the smelting furnace for each smelting through the weight sensor on the secondary conveyor belt, and records it for the operator to review afterwards. The monitoring process is as follows: during initialization, the loading amount is set to 0; if the controller detects that the detection value of the weight sensor on the secondary conveyor belt changes from 0 to any non-zero value, the loading amount monitoring is started. If a weight sensor changes from non-zero to zero, the value before it changes to zero is added to the loading amount. For example, if the first weight sensor changes from 5kg to 0kg, the cumulative loading amount is 0+5=5kg. If the second weight sensor changes from 5kg to 0kg, the cumulative loading amount is 5+5=10kg. This is repeated until the detection values ​​of all weight sensors on the secondary conveyor belt change to 0. The current value of the loading amount is recorded as the loading amount for this time, and the loading amount monitoring ends. In this way, the actual loading amount put into the melting furnace for each smelting can be detected, so that the operator can confirm whether the loading amount is the target amount after review.

[0024] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
