Description

Technical Field

[0001] This invention relates to the field of metal waste treatment technology, and in particular to an intelligent metal waste treatment device. Background Technology

[0002] Waste materials generated during the production processes of steel mills, recycling industries, and non-ferrous and ferrous metal smelting industries (steel shavings, scrap steel, scrap aluminum, scrap copper, scrap stainless steel, and scrapped automobiles, etc.) need to be centrally processed and usually require remelting. To reduce the transportation and smelting costs of metal scrap and increase the speed of furnace feeding, hydraulic balers are generally used to compress various metal scrap materials into solid blocks of a certain shape. However, the resulting metal blocks are large in weight and volume, posing problems such as difficulties in manual handling and reduced smelting efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent metal waste processing device to solve the problems of existing metal waste processing devices causing difficulties in manual handling of metal waste and reduced smelting efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0005] A smart metal waste processing device includes a feeding component, a control component, and a melting component;

[0006] The feeding component includes a roll box, inside which a roll is provided, and a long plastic bag is wound around the roll.

[0007] The control component includes a sliding frame, which includes a first clamping section and a second clamping section. The two sliding frames are symmetrically arranged and can move towards each other so that the first clamping section and the second clamping section respectively clamp the suspended plastic bag.

[0008] The melting component is disposed between the first clamping section and the second clamping section, and includes a hot melt clamping plate; the two melting components move toward each other so that the hot melt clamping plate clamps the suspended plastic bag and heats it.

[0009] Furthermore, the intelligent metal waste processing device also includes a reference frame, which is disposed between the two sliding frames and slidably connected to the two sliding frames;

[0010] The reference frame includes a hollow plate, a return spring, and a built-in air pump;

[0011] The long plastic bag passes through the opening of the hollow plate; one end of the return spring is connected to the hollow plate, and the other end is connected to the sliding frame, for applying a pushing force to the sliding frame to drive the sliding frame to move toward the long plastic bag;

[0012] The reference frame is inserted into the sliding frame and forms a starting space with the sliding frame; the built-in air pump is installed in the hollow plate and communicates with the starting space.

[0013] The built-in air pump draws air to reduce the air pressure in the activation space, thereby causing the return spring to push the sliding frame toward the long plastic bag; the built-in air pump injects air into the activation space to push the sliding frame away from the long plastic bag and compress the return spring.

[0014] Furthermore, the intelligent metal waste processing device includes two reference frames, which are slidably connected to the first clamping section and the second clamping section, respectively.

[0015] The reference frame includes two sets of reset springs. One set of the reference frame is connected to the first clamping section to form two starting spaces. One end of each set of reset springs is connected to the hollow plate, and the other end is connected to the two first clamping sections respectively.

[0016] Another reference frame is connected to the second clamping section to form two starting spaces. One end of each of the two sets of reset springs is connected to the hollow plate, and the other end is connected to the two second clamping sections respectively.

[0017] Furthermore, the control component also includes a friction roller rod, which is mounted on the sliding frame and abuts against the molten material component;

[0018] The friction roller rotates around its own axis to move the melting component closer to or away from the plastic bag.

[0019] Furthermore, the control component also includes an arc-shaped guide plate, one end of which is connected to the sliding frame, and the other end of which abuts against the melting component;

[0020] The melting component is provided with a conductive groove. The friction roller drives the melting component to move toward the plastic bag and causes the arc-shaped guide plate to engage with the conductive groove so that the hot melt clamp is energized.

[0021] Furthermore, the melting component also includes a sliding receiving frame, a flow guide plate, and a one-way fan blade;

[0022] The conductive groove is formed in the sliding receiving frame, the flow guide plate is installed in the sliding receiving frame, and the unidirectional fan blade is installed in the flow guide plate;

[0023] The unidirectional fan blades are used to blow air onto the long plastic bag.

[0024] Furthermore, the melting component also includes a built-in baffle and a limiting spring;

[0025] The sliding receiving frame is provided with a flow-guiding groove, through which the airflow blown out by the one-way fan blade flows to the plastic long bag;

[0026] The built-in baffle is hinged to the sliding receiving frame; one end of the limiting spring is connected to the sliding receiving frame and the other end is connected to the built-in baffle, configured to apply a pulling force to the built-in baffle to make the built-in baffle swing away from the plastic bag;

[0027] The airflow from the unidirectional fan blades pushes the built-in baffle to swing towards the plastic bag, thereby cooling the hot-melt part of the plastic bag.

[0028] Furthermore, the melting component also includes a side rotating arm, one end of which is hinged to the sliding receiving frame and the other end of which is hinged to the sliding frame;

[0029] The side swing arm is configured to extend and retract along its own length.

[0030] Furthermore, the intelligent metal waste processing device also includes a pressurizing component, which includes a pressing roller shaft, a sleeve shell, and a horizontal push plate;

[0031] The extrusion roller shaft is rotatably mounted on the sleeve shell; one end of the horizontal push plate is connected to the sleeve shell, and the other end is connected to the sliding frame, which is used to drive the sleeve shell and the extrusion roller shaft to move the plastic bag.

[0032] Furthermore, the pressurizing component also includes a force-receiving push rod, a surface-mounting push plate, and a pressure-sensing inner plate;

[0033] The force-bearing push rod is connected to the sleeve shell; one end of the face-fitting push plate is slidably connected to the pressure-sensitive inner plate, and the other end is connected to the force-bearing push rod; the pressure-sensitive inner plate is connected to the sliding frame and is used to measure the tension between the face-fitting push plate and the pressure-sensitive inner plate.

[0034] In summary, the technical effects achieved by this invention are as follows:

[0035] 1. This device maintains the original size of metal scrap by packaging it in long plastic bags, which facilitates rapid melting during smelting, ensuring smelting efficiency and also allows for long-term storage. At the same time, the long plastic bags can be rolled up and released to flexibly select the volume and weight of each packaged piece of metal scrap according to the layout of handling tools and storage sites, making it convenient to repackage metal scrap according to different scenarios and needs.

[0036] 2. This device can clamp and limit the expansion of the long plastic bag through the sliding frames on both sides, keeping the long plastic bag in a fixed position inside the control component. At this time, the bag inside will remain vertical due to the clamping and limiting effect of the sliding frames on both sides. Then, the sliding receiving frame in the middle of the sliding frame will further push the hot melt clamp to perform hot melt sealing on the limited long plastic bag. This avoids the situation of the suspended bag tilting, swinging, and uneven heating when directly heat-processing the long plastic bag, ensuring the firmness and tightness of the hot melt seal.

[0037] 3. The melting component of this device performs heat-sealing processing on plastic bags through a hot-melt clamp. When the sliding receiving frame does not reach the designated position, the arc-shaped guide plate cannot supply power to the melting component, that is, the heating internal resistance and the hot-melt clamp cannot be powered. Therefore, the melting component will not consume electricity to heat up when it is not in operation, which can save energy and avoid the problem of injury caused by the hot-melt clamp when it is not in operation.

[0038] 4. The sliding receiving frame of this device can use the internal diversion plate and unidirectional fan blades to air cool the part of the plastic bag after it has been heated through the diversion groove. During the air cooling process, the sliding receiving frame slides outward continuously, and under the guidance of the built-in baffle, the air force is always blown obliquely and towards the heating area. The heating part of the plastic bag is located inside the closed sliding frame and is in a clamped state. Therefore, the plastic bag will not have uneven heating or shake due to the air force, thus ensuring the overall stability of the plastic bag.

[0039] 5. After the horizontal push plate advances the sleeve shell, if the sleeve shell slips relative to the horizontal push plate, the sleeve shell will pull the force-bearing push rod, which will then push the face-fitting push plate to slide along the inner wall of the pressure-sensitive inner plate. Through the force action inside the pressure-sensitive inner plate, the thrust of the horizontal push plate on the sleeve shell is adjusted, thus avoiding the problem of the extrusion roller shaft becoming loose when squeezing the plastic bag, which would prevent the extrusion roller shaft from effectively stretching the plastic bag.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0052] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0053] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] Existing metal scrap processing equipment typically compresses various metal scraps into blocks of a certain shape. However, the resulting metal blocks are large in mass and volume, which poses problems such as difficulty in manual handling and reduced smelting efficiency.

[0055] In view of this, the present invention provides an intelligent metal waste processing device, comprising a feeding component 100, a control component 200, a melting component 300, a reference frame 400, a pressurizing component 500, and a support frame 600, as shown below. Figure 1 , Figure 4 As shown, the feeding component 100 and the reference frame 400 are mounted on the support frame 600, the control component 200 is slidably connected to the reference frame 400, the melting component 300 is slidably mounted on the control component 200, and the pressurizing component 500 is mounted on the control component 200. Specifically, the feeding component 100 is used to output the long plastic bag 120, the control component 200 is used to clamp the long plastic bag 120 to prevent the bag from tilting, wrinkling, or swaying, the melting component 300 is used to heat-melt the long plastic bag 120 to complete the sealing, and the pressurizing component 500 is used to tighten the long plastic bag 120 to prevent wrinkles. Specifically, the long plastic bag 120 is a hollow bag with a feeding port along its length.

[0056] The following combination Figures 1-9 The structure and shape of the intelligent metal waste processing device provided in this embodiment are described in detail below:

[0057] In this embodiment, the feeding component 100 includes a roll box 110 and a motor. A roll is disposed inside the roll box 110, and a long plastic bag 120 is wound around the roll. The motor drives the roll box 110 to rotate around its own axis to release the long plastic bag 120, facilitating the sorting of metal waste and the selection of different lengths of the long plastic bag 120. After release, the long plastic bag 120 is in a suspended state, such as... Figure 2 As shown.

[0058] In this embodiment, the control component 200 includes two sliding frames 210, each sliding frame 210 including a first clamping section 211 and a second clamping section 212, such as... Figure 4As shown, the first clamping section 211 is located above the second clamping section 212. The two sliding frames 210 are symmetrically arranged and can move towards each other so that the two first clamping sections 211 and the two second clamping sections 212 clamp the suspended plastic bag 120 from the upper and lower ends respectively to fix it.

[0059] In this embodiment, two reference frames 400 are provided to cooperate with the sliding frame 210. Specifically, the two reference frames 400 are arranged in parallel and vertically, that is, the two reference frames 400 and the two sliding frames 210 can form a rectangle, such as... Figure 4 As shown, the reference frame 400 is disposed between two sliding frames 210 and slidably connected to the sliding frames 210. In this embodiment, the reference frame 400 includes a hollow plate 410, which is connected to the support frame 600 for fixation. A rectangular opening is provided in the middle of the hollow plate 410 to allow the long plastic bag 120 to pass through. Sliding grooves are provided on both the first clamping section 211 and the second clamping section 212. The hollow plates 410 of the two reference frames 400 are respectively inserted into the sliding grooves of the first clamping section 211 and the second clamping section 212 and slidably connected to the first clamping section 211 and the second clamping section 212.

[0060] In this embodiment, the reference frame 400 also includes a return spring 420 and a built-in air pump 430, such as Figure 8 As shown. One end of the return spring 420 is connected to the hollow plate 410, and the other end is connected to the sliding frame 210. It is used to apply a pushing force to the sliding frame 210 to move the sliding frame 210 towards the plastic long bag 120. Specifically, one hollow plate 410 and the sliding grooves on the two first clamping sections 211 form two starting spaces 101, and another hollow plate 410 and the sliding grooves on the two second clamping sections 212 form two starting spaces 101. That is, the two hollow plates 410 and the two sliding frames 210 together form four starting spaces 101.

[0061] Furthermore, the reference frame 400 is equipped with two sets of return springs 420, which are respectively connected to the two sliding frames 210 to drive the two sliding frames 210 to move towards each other, thereby clamping the plastic bag 120, as shown. Figure 4 As shown, a reference frame 400 is connected to the first clamping section 211 to form two starting spaces 101. One end of each of the two sets of return springs 420 is connected to the hollow plate 410, and the other end is connected to the two first clamping sections 211 respectively. Another reference frame 400 is connected to the second clamping section 212 to form two starting spaces 101. One end of each of the two sets of return springs 420 is connected to the hollow plate 410, and the other end is connected to the two second clamping sections 212 respectively.

[0062] In this embodiment, an external nozzle 401 is provided on the hollow plate 410, and a built-in air pump 430 is installed on the hollow plate 410 and communicates with the start-up space 101 through the external nozzle 401. During operation, the built-in air pump 430 draws air to reduce the air pressure in the start-up space 101, thereby causing the return spring 420 to push the sliding frame 210 to move towards the plastic bag 120, so that the two sliding frames 210 clamp the plastic bag 120; when releasing the plastic bag 120, the built-in air pump 430 injects air into the start-up space 101 to push the sliding frame 210 away from the plastic bag 120 and compress the return spring 420.

[0063] In this embodiment, the control component 200 further includes a friction roller 220 and an arc-shaped guide plate 230, such as Figure 4 As shown; the molten material component 300 includes a hot-melt clamping plate 310 and a sliding receiving frame 320. The hot-melt clamping plate 310 is connected to the sliding receiving frame 320, and a conductive groove 321 is formed on the sliding receiving frame 320, as shown. Figure 5 , Figure 6 As shown. The friction roller 220 is mounted on the sliding frame 210 and abuts against the sliding receiving frame 320. One end of the arc-shaped guide plate 230 is connected to the sliding frame 210, and the other end abuts against the sliding receiving frame 320. Specifically, the friction roller 220 can be driven by a motor to rotate around its own axis, thereby causing the sliding receiving frame 320 to move closer to or away from the plastic bag 120, and in turn, causing the hot melt clamping plate 310 to move closer to or away from the plastic bag 120. When the two hot melt clamping plates 310 move towards each other and clamp the plastic bag 120, the arc-shaped guide plate 230 engages with the conductive groove 321 to energize the hot melt clamping plate 310. When the two hot melt clamping plates 310 move away from each other under the action of the friction roller 220, the arc-shaped guide plate 230 disengages from the conductive groove 321 to de-energize the hot melt clamping plate 310.

[0064] Specifically, a receiving groove 201 is provided in the middle of the sliding frame 210. A sliding receiving frame 320 is inserted into the receiving groove 201 and slidably connected to the sliding frame 210. The sliding receiving frame 320 is located between the first clamping section 211 and the second clamping section 212. Two friction rollers 220 are installed on each sliding frame 210. The two friction rollers 220 are located on the upper and lower sides of the sliding receiving frame 320 respectively and are used to drive one sliding receiving frame 320. The arc-shaped guide plate 230 can be made of elastic material, or a telescopic block can be provided at the end of the arc-shaped guide plate 230 that abuts against the melting component 300. The telescopic block is connected to the melting component 300 by spring thrust. When the arc-shaped guide plate 230 moves to the conductive groove 321, the telescopic block is inserted into the conductive groove 321 under the thrust of the spring to achieve conductivity.

[0065] In addition, a step is provided on the sliding receiving frame 320, and the friction roller 220 can abut against the step for limiting. When the friction roller 220 drives the sliding receiving frame 320 to approach the plastic long bag 120, the friction roller 220 can finally abut against the step, so as to avoid the hot melt clamp 310 from excessively squeezing the plastic long bag 120 and affecting the hot melt sealing effect.

[0066] In the optional embodiment, the molten material component 300 includes the guide plate 330 and the unidirectional fan blade 340, as shown below. Figure 7 As shown, the deflector plate 330 is mounted on the sliding receiving frame 320, and the one-way fan blade 340 is mounted on the deflector plate 330. The one-way fan blade 340 is used to blow air onto the plastic long bag 120 for cooling.

[0067] In this embodiment, the melting component 300 further includes a built-in baffle 350 and a limiting spring 360, and the sliding receiving frame 320 is provided with a drainage groove 322, such as Figure 6 As shown, the airflow from the unidirectional fan blade 340 flows to the plastic long bag 120 via the guide groove 322. Specifically, the built-in baffle 350 is hinged to the sliding receiving frame 320; one end of the limiting spring 360 is connected to the sliding receiving frame 320, and the other end is connected to the built-in baffle 350, configured to apply a pulling force to the built-in baffle 350 to make the built-in baffle 350 swing away from the plastic long bag 120. The airflow from the unidirectional fan blade 340 pushes the built-in baffle 350 to make the built-in baffle 350 swing closer to the plastic long bag 120, and then the airflow, guided by the built-in baffle 350, blows towards the hot-melt area to cool the hot-melt area of ​​the plastic long bag 120. In this embodiment, built-in baffles 350 are provided on both the upper and lower sides of the hot-melt clamping plate 310 so that the airflow flowing through the built-in baffles 350 flows towards the middle of the hot-melt clamping plate 310, thereby cooling the hot-melt part of the plastic long bag 120.

[0068] In an optional embodiment, the melting component 300 further includes a side-mounted rotating arm 370, one end of which is hinged to the sliding receiving frame 320, and the other end is hinged to the sliding frame 210. The side-mounted rotating arm 370 is configured to extend and retract along its own length to ensure the balance of the sliding receiving frame 320 and to prevent the sliding receiving frame 320 from detaching. The side-mounted rotating arm 370 may be a cylinder, a spring telescopic rod, or a similar structure, maintaining a retracting tendency during operation and providing tension to the sliding receiving frame 320.

[0069] In this embodiment, to improve circuit safety, the molten material component 300 also includes a heating internal resistance 380, which is connected in series with the hot melt clamping plate 310.

[0070] In this embodiment, the pressurizing component 500 includes an extrusion roller shaft 510, a sleeve shell 520, a horizontal push plate 530, a force-bearing push rod 540, a surface-fitting push plate 550, and a pressure-sensing inner plate 560. Figure 9As shown. The extrusion roller shaft 510 is rotatably mounted on the sleeve housing 520; one end of the horizontal push plate 530 is connected to the sleeve housing 520, and the other end is connected to the sliding frame 210, used to drive the sleeve housing 520 and the extrusion roller shaft 510 to move towards the plastic long bag 120; the force-bearing push rod 540 is connected to the sleeve housing 520; one end of the bonding push plate 550 is slidably connected to the pressure-sensing inner plate 560, and the other end is connected to the force-bearing push rod 540; the pressure-sensing inner plate 560 is connected to the sliding frame 210, used to measure the tension between the bonding push plate 550 and the pressure-sensing inner plate 560. Both ends of the extrusion roller shaft 510 and the force-bearing push rod 540 are connected to the sleeve housing 520. A motor is installed inside the sleeve housing 520 to drive the extrusion roller shaft 510 to rotate. The horizontal push plate 530 can be configured as a cylinder or an electric telescopic rod.

[0071] After the plastic bag 120 is clamped by the sliding frame 210, the horizontal push plate 530 pushes the sleeve shell 520 and the extrusion roller shaft 510, causing the extrusion roller shaft 510 to abut against the plastic bag 120. Subsequently, the extrusion roller shaft 510 rotates around its own axis to tighten the plastic bag 120 in the vertical direction, thereby eliminating loose and swollen parts and wrinkles in the bag. The pressure-sensitive inner plate 560 can obtain the pressure of the extrusion roller shaft 510 through the force-bearing push rod 540 and the surface-fitting push plate 550, thereby ensuring that the extrusion roller shaft 510 applies sufficient pressure to the plastic bag 120 to avoid loosening and to ensure that the extrusion roller shaft 510 effectively tightens the plastic bag 120.

[0072] In this embodiment, to control the volume and weight of a single package, the intelligent metal waste processing device also includes distance sensors. Two sets of distance sensors are respectively positioned below the melting component 300 and on both sides of the plastic long bag 120 to detect the width change of the plastic long bag 230 after it is filled with metal waste. By monitoring the dimensional changes of the plastic long bag 120, its volume change is monitored, thereby controlling its weight. Specifically, each set of distance sensors includes multiple distance sensors arranged along the height direction for more accurate monitoring of volume changes. Alternatively, a camera can also be used to monitor volume changes.

[0073] In an optional embodiment, the intelligent metal waste processing device further includes a cutting component and a conveying component. The cutting component includes a cutter and a pad respectively disposed on both sides of the plastic long bag 120. The cutter and the pad work together to separate two adjacent bags of metal waste, with the separation point being the heat-sealing location. The cut and packaged metal waste falls into the conveying component for transport. Specifically, the conveying component can be configured as a conveyor belt.

[0074] The working process of the intelligent metal waste processing device provided in this embodiment is as follows:

[0075] The feeding component 100 releases the plastic long bag 120, and then the built-in air pump 430 draws air to reduce the air pressure in the starting space 101, thereby causing the return spring 420 to push the sliding frame 210 to move. At this time, the two sliding frames 210 move towards each other so that the first clamping section 211 and the second clamping section 212 clamp the plastic long bag 120 from the top and bottom respectively.

[0076] At the same time, the friction roller 220 rotates to drive the sliding receiving frame 320 to move, thereby causing the two hot melt clamps 310 to move towards each other and clamp the plastic long bag 120. At this time, the arc-shaped guide plate 230 is inserted into the conductive groove 321 to energize the hot melt clamps 310, thereby completing the hot melting of the plastic long bag 120.

[0077] Before the hot melt clamping plate 310 clamps the plastic long bag 120, the horizontal push plate 530 pushes the sleeve shell 520 and the extrusion roller shaft 510 and makes the extrusion roller shaft 510 abut against the plastic long bag 120. The extrusion roller shaft 510 rotates around its own axis to tighten the plastic long bag 120, thereby eliminating wrinkles.

[0078] After the first heat melting is completed, the friction roller 220 rotates in the opposite direction to move the two melting components 300 away from each other. At the same time, the unidirectional fan blade 340 rotates to blow air towards the heat melting area through the flow guide groove 322, and guides the airflow through the built-in baffle 350. This causes the heat melting clamp 310 to move away from the plastic bag 120 and cool the heat melting area. At this time, the sliding frame 210 still holds the plastic bag 120 to prevent it from being affected by the airflow. Subsequently, the built-in air pump 430 injects air into the starting space 101 to increase the pressure in the starting space 101, which in turn causes the two sliding frames 210 to move away from each other and compress the return spring 420. The plastic bag 120 returns to its free state, and at this time, the pressure component 500 also moves away from the plastic bag 120.

[0079] Subsequently, the feeding component 100 continues to release the plastic bag 120 and injects metal scrap through the feeding port on the plastic bag 120.
