Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet leveling machines, specifically to an automatic feeding mechanism for metal sheet leveling machines. Background Technology

[0002] Sheet metal refers to flat, rectangular building material sheets made into standard sizes. It also refers to metal sheets that are forged, rolled, or cast. They are classified into thin plates, medium plates, thick plates, and extra-thick plates. Currently, metal sheet metal parts are generally processed by stamping, bending, stretching, and other methods. Among these processes, the flatness of the sheet metal surface has a significant impact on the performance of the components. Therefore, it is necessary to perform appropriate shaping processing on the sheet metal surface before putting it into practical application. Here, shaping processing refers to restoring the deformed parts of the sheet metal to their original shape.

[0003] After a sheet metal sheet is stamped and leveled by a sheet metal stamping press, it is often manually handled and unloaded through a roller conveyor at its discharge port. Because the sheet metal is heavy, this results in a large workload, increased labor costs, and reduced processing efficiency. Although existing technologies include methods to receive the sheet metal by placing a receiving box at the discharge port, these methods have the following drawbacks:

[0004] While placing a receiving box at the discharge outlet can directly collect the discharged metal sheets, the initial collection of multiple metal sheets presents a significant impact due to the large height difference between the receiving and discharge outlets. This poses a risk of metal sheet collision and breakage, and cannot guarantee the horizontal and stable anti-impact collection of the metal sheets. In view of this, this application proposes an automatic unloading mechanism for a metal sheet leveling machine to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding mechanism for a metal sheet leveling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding mechanism for a metal sheet leveling machine, comprising an automatic feeding mechanism body installed on the right side of the discharge port conveyor of the metal sheet leveling machine, the automatic feeding mechanism body comprising a U-shaped support plate, wherein a receiving component is movably contacted between the inner walls of the two sides of the U-shaped support plate.

[0007] The receiving assembly includes a receiving box that is movably in contact between the inner walls of both sides of the U-shaped support plate. The top and left side of the receiving box are both open. The inner wall of the left side of the U-shaped support plate has a feeding hole for the metal sheet to enter and communicate with the receiving box. The four corners of the bottom of the receiving box are rotatably mounted with casters. The top of the receiving box is fixedly connected to two U-shaped handles, and the top inner wall of the U-shaped handles is fixedly connected to a locking rod. The receiving box is used to receive the metal sheet when it is fed in.

[0008] An electric hoist is fixedly installed on the top of the U-shaped support plate. A PLC controller is fixedly and electrically connected to the front of the electric hoist. The bottom end of the electric hoist's own wire rope extends into the U-shaped support plate and is fixedly connected to a U-shaped rod. A lifting plate that is slidably sleeved on the U-shaped support plate is fixedly connected to the bottom end of the U-shaped rod. A snap-fit ​​pulling assembly for pulling and lowering the two U-shaped handles is installed on the lifting plate. A vertical guide assembly is fixedly connected between the top of the lifting plate and the left inner wall of the U-shaped support plate. A distance measuring assembly that is electrically connected to the PLC controller and used to measure the lifting distance is fixedly connected between the top inner wall of the U-shaped support plate and the top of the U-shaped rod. The electric hoist is used to lower and lift the U-shaped rod. The snap-fit ​​traction assembly is used to lower or pull the two U-shaped handles when the U-shaped rod is lowered and lifted, thereby lowering or pulling the receiving box. The distance measuring assembly is used to measure the downward distance of the U-shaped rod in real time and transmit it to the PLC controller. This allows the PLC controller to control the lowering distance of the electric hoist according to the metal sheet thickness, so that the metal sheet can enter the receiving box smoothly and continuously. This prevents the metal sheet from falling directly and colliding, causing serious damage or bending due to the low position. The vertical guide assembly is used to guide the lifting plate vertically when it is lowered.

[0009] Preferably, the snap-fit ​​traction assembly includes a rectangular sliding sleeve that is slidably sleeved on the outside of the lifting plate. The bottom of the rectangular sliding sleeve is fixedly connected to two L-shaped hook rods that are respectively hooked to the inside of the corresponding U-shaped handles. The bottom inner wall of the L-shaped hook rod is provided with a locking hole for movably engaging with the corresponding locking rod. An electric telescopic rod is fixedly installed on the top inner wall of the U-shaped rod. A connecting seat is fixedly connected between the extended end of the electric telescopic rod and the top of the rectangular sliding sleeve.

[0010] Preferably, the vertical guide assembly includes two vertical guide rods fixedly connected to the top left side of the lifting plate, and two vertical guide sleeves fixedly connected to the left inner wall of the U-shaped support plate, which are respectively slidably fitted onto the outer side of the corresponding vertical guide rods, and the U-shaped support plate is slidably fitted onto the two vertical guide rods.

[0011] Preferably, the ranging assembly includes a reference plate fixedly connected to the top of the U-shaped rod, and a laser ranging sensor fixedly connected to the inner wall of the top of the U-shaped support plate is disposed above the reference plate. The laser ranging sensor is electrically connected to the PLC controller.

[0012] Preferably, the right side of the discharge port conveyor of the metal sheet leveling machine extends into the feed hole, and an inclined support rod is fixedly connected between the bottom right side of the discharge port conveyor of the metal sheet leveling machine and the left side of the U-shaped support plate.

[0013] Preferably, a fixing seat is fixedly connected to the bottom of both sides of the U-shaped support plate, and two mounting holes are opened on the top of the fixing seat. A diagonal brace is fixedly connected between the top of the fixing seat and the outer side of the U-shaped support plate.

[0014] Preferably, the top right side of the lifting plate has a rectangular guide hole that slides in contact with the outer side of the U-shaped support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the coordinated use of an electric hoist, PLC controller, U-shaped support plate, U-shaped rod, lifting plate, snap-fit ​​traction assembly, vertical guide assembly, ranging assembly, U-shaped handle, casters, and receiving box, it can stably and horizontally receive metal sheets. After receiving each metal sheet, it can accurately and automatically adjust the receiving box to ensure that each metal sheet is in a horizontal discharge and collection state. This achieves a continuous, stable, and anti-impact collection effect for metal sheets, avoiding damage and bending caused by falling due to large drop differences and the weight of the metal sheets. This improves the stability and safety of material discharge and collection.

[0017] 2. Through the combination of the snap-fit ​​pull assembly, U-shaped handle, locking rod and receiving box, the locking state with the locking rod can be released when it is lowered to the lowest position, and the hook restriction state of the U-shaped handle can be easily released.

[0018] This utility model features a series of structures that facilitate the horizontal and stable reception of metal sheets. After each metal sheet is received, the receiving box is precisely and automatically adjusted for lowering. This achieves a continuous, horizontal, and stable anti-impact collection of the metal sheets, preventing damage and bending caused by falling due to large drop differences or the weight of the metal sheets. This improves the stability and safety of material collection and makes it easy to remove and replace the sheets when the receiving box is full, eliminating the need for manual lifting and making it convenient for users.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, the automatic feeding mechanism for the metal sheet leveling machine proposed in this embodiment includes an automatic feeding mechanism body installed on the right side of the discharge port conveyor 100 of the metal sheet leveling machine. The automatic feeding mechanism body includes a U-shaped support plate 2. A receiving component is movably contacted between the inner walls of both sides of the U-shaped support plate 2. A fixed seat is fixedly connected to the bottom of both sides of the U-shaped support plate 2. Two mounting holes are opened on the top of the fixed seat. An inclined brace is fixedly connected between the top of the fixed seat and the outer side of the U-shaped support plate 2, which has the effect of reinforcing and supporting the U-shaped support plate 2.

[0025] The receiving assembly includes a receiving box 1 that is movably in contact between the inner walls of both sides of the U-shaped support plate 2. The top and left side of the receiving box 1 are both open. The inner wall of the left side of the U-shaped support plate 2 has a feed hole 201 for metal sheets to enter and communicate with the receiving box 1. The right side of the metal sheet leveling machine discharge port conveyor 100 extends into the feed hole 201. The bottom right side of the metal sheet leveling machine discharge port conveyor 100 is fixedly connected to the left side of the U-shaped support plate 2 with an inclined support rod. The four corners of the bottom of the receiving box 1 are rotatably mounted with casters 101. The top of the receiving box 1 is fixedly connected with two U-shaped handles 102. The inner wall of the top of the U-shaped handles 102 is fixedly connected with a locking rod 103. The receiving box 1 is used to receive metal sheets when they are fed in.

[0026] An electric hoist 4 is fixedly installed on the top of the U-shaped support plate 2. A PLC controller 401 is fixedly and electrically connected to the front of the electric hoist 4. The bottom end of the wire rope of the electric hoist 4 extends into the U-shaped support plate 2 and is fixedly connected to a U-shaped rod 301. A rectangular movable through hole for the wire rope to pass through is opened on the top inner wall of the U-shaped support plate 2. A lifting plate 3 that slides on the U-shaped support plate 2 is fixedly connected to the bottom end of the U-shaped rod 301. A rectangular guide hole is opened on the top right side of the lifting plate 3 to slide in contact with the outer side of the U-shaped support plate 2, which serves to guide the vertical sliding of the lifting plate 3. A snap-fit ​​pulling assembly for pulling and lowering the two U-shaped handles 102 is installed on the lifting plate 3. A vertical guide assembly is fixedly connected between the top of the lifting plate 3 and the left inner wall of the U-shaped support plate 2. A ranging component, which is electrically connected to the PLC controller 401 and used to measure the lifting distance, is fixedly connected between the top of 01. The electric hoist 4 is used to lower and lift the U-shaped rod 301. The snap-fit ​​pulling component is used to lower or pull the two U-shaped handles 102 when the U-shaped rod 301 is lowered and lifted, driving the lifting plate 3 to rise and fall, thereby realizing the lowering or pulling of the receiving box 1. The ranging component is used to measure the downward distance of the U-shaped rod 301 in real time and transmit it to the PLC controller 401, so that the PLC controller 401 can control the lowering distance of the electric hoist 4 each time according to the metal plate of different thicknesses, so that the metal plate can enter the receiving box 1 smoothly and continuously, preventing the metal plate from falling directly and colliding due to the low position, causing serious damage or bending again. The vertical guide component is used to guide the lifting plate 3 vertically when it is lowered and raised.

[0027] Specifically, the snap-fit ​​traction assembly includes a rectangular sliding sleeve 603 slidably sleeved on the outside of the lifting plate 3. Two L-shaped hook rods 601 are fixedly connected to the bottom of the rectangular sliding sleeve 603, each hooking onto the inner side of a corresponding U-shaped handle 102. The bottom inner wall of the L-shaped hook rod 601 has a locking hole 602 for movably engaging with the corresponding hook rod 103. An electric telescopic rod 6 is fixedly installed on the top inner wall of the U-shaped rod 301. A connecting seat is fixedly connected between the extended end of the electric telescopic rod 6 and the top of the rectangular sliding sleeve 603. The rectangular sliding sleeve 603, L-shaped hook rods 601, and locking holes 602 work together to allow the lifting plate 3 to rise and fall. The rectangular sliding sleeve 603 and the two L-shaped hooks 601 are used to lower or pull up the two U-shaped handles 102 in sequence. When the receiving box 1 is lowered to the lowest position and can no longer move down, the lifting plate 3, which continues to move down, is driven by the rectangular sliding sleeve 603 and the L-shaped hooks 601 to separate the locking hole 602 from the locking rod 103. The electric telescopic rod 6 drives the rectangular sliding sleeve 603 to move to the left. The rectangular sliding sleeve 603 drives the two L-shaped hooks 601 to the left and separate them from the corresponding U-shaped handles 102. The receiving box 1 can then be pushed forward or backward by the universal wheels 101, making it convenient to replace the new receiving box 1 and continue receiving materials.

[0028] Furthermore, the vertical guide assembly includes two vertical guide rods 5 fixedly connected to the top left side of the lifting plate 3. Two vertical guide sleeves 501 are fixedly connected to the inner left side of the U-shaped support plate 2, which are respectively slidably fitted onto the outer side of the corresponding vertical guide rods 5. The U-shaped support plate 2 is slidably fitted onto the two vertical guide rods 5. Two vertical guide holes are opened on the top inner wall of the U-shaped support plate 2, which are respectively slidably fitted onto the outer side of the corresponding vertical guide rods 5, so as to guide the vertical sliding of the vertical guide rods 5. The vertical guide rods 5 and the vertical guide sleeves 501 cooperate to drive the two vertical guide rods 5 to slide vertically in the corresponding vertical guide sleeves 501 when the lifting plate 3 is raised or lowered, so as to perform vertical guiding work.

[0029] Furthermore, the ranging component includes a reference plate 701 fixedly connected to the top of the U-shaped rod 301. Above the reference plate 701, a laser ranging sensor 7 is fixedly connected to the inner wall of the top of the U-shaped support plate 2. The laser ranging sensor 7 is electrically connected to the PLC controller 401. The reference plate 701 and the laser ranging sensor 7 work together to move the reference plate 701 up and down as the U-shaped rod 301 moves. The laser ranging sensor 7 measures the distance between itself and the reference plate 701 in real time and transmits the distance value to the PLC controller 401. The PLC controller 401 sets the distance increase for each downward movement according to the different thicknesses of the metal plates. When the corresponding preset value is reached each time, the PLC controller 401 controls the electric hoist 4 to automatically shut down. This achieves the effect of precise and automatic downward adjustment after receiving each metal plate, facilitating the continuous and flat entry of the metal plates into the receiving box 1. It prevents the metal plates from falling directly and colliding due to their low position, which could cause serious damage or bending. This achieves a safe, stable, and automatic unloading effect.

[0030] The method of use in this embodiment is as follows: The operator first starts the electric hoist 4 in the forward direction, causing its driving wire rope to pull and lift the U-shaped rod 301. The U-shaped rod 301 drives the lifting plate 3 to slide upwards on the U-shaped support plate 2. The lifting plate 3 drives the two vertical guide rods 5 to slide upwards within their respective vertical guide sleeves 501. The lifting plate 3 then pulls the two U-shaped handles 102 upwards via the rectangular sliding sleeve 603 and the two L-shaped hook rods 601. The U-shaped handles 102 drive the receiving box 1 upwards. When the bottom inner wall of the receiving box 1 moves upwards to be level with the top of the metal sheet leveling machine's discharge port conveyor 100, the electric hoist 4 is turned off. The PLC controller 401 is used to preset the distance value for each time the electric hoist 4 is turned off according to the different thicknesses of the metal sheet. When the metal sheet leveling machine's discharge port conveyor 100 outputs the metal sheet to the right, the metal sheet directly and smoothly enters the receiving box 1. Each time a sheet enters, the operator starts the electric hoist 4 in the reverse direction once. Similarly, the movement direction of the electric hoist 4 is completely opposite to that of the forward-starting electric hoist 4. At this time, both the U-shaped rod 301 and the receiving box 1 change to moving downward. When the U-shaped rod 301 moves downward, it will drive the reference plate 701 to move downward as a whole. The laser range sensor 7 measures the distance between itself and the reference plate 701 in real time and transmits the distance value to the PLC controller 401. When the corresponding preset value is reached each time the lowering reaches the set value, the PLC controller 401 controls the electric hoist 4 to automatically shut down. This achieves the effect of accurately and automatically adjusting the lowering of the receiving box 1 after receiving each metal plate, so that the top of the metal plate to be entered is flush with the top of the metal plate that has already entered. This makes it convenient for the metal plate to be entered to continue to enter the receiving box 1 flat. This process is repeated to achieve the effect of safe and stable automatic material feeding, thereby achieving the effect of continuous horizontal and stable anti-impact collection of metal plates. This avoids the phenomenon of damage and bending caused by falling and impact due to large drop and heavy metal plates, thus improving the stability and safety of material feeding and collection.

[0031] As the receiving box 1 and the lifting plate 3 move downwards, when the receiving box 1 reaches its lowest position and can no longer move downwards, the lifting plate 3, which continues to move downwards, sequentially uses the rectangular sliding sleeve 603 and the L-shaped hook rod 601 to drive the locking hole 602 downwards and separate it from the locking rod 103. Then, the personnel start the electric telescopic rod 6 in the forward direction to drive the rectangular sliding sleeve 603 to move to the left. The rectangular sliding sleeve 603 drives the two L-shaped hook rods 601 to the left, which are respectively offset from the corresponding U-shaped handles 102. The receiving box 1 can then be pushed forward or backward by the universal wheels 101. Then, the new receiving box 1 is pushed into the inside of the U-shaped support plate 2. Then, the electric telescopic rod 6 is started in the reverse direction to drive the rectangular sliding sleeve 603 to move to the right. The rectangular sliding sleeve 603 drives the two L-shaped hook rods 601 to move to the right. The rod 601 is inserted into the corresponding U-shaped handle 102 to the right. Then, the electric hoist 4 is started again to drive the U-shaped rod 301 and the lifting plate 3 to rise. The lifting plate 3 is driven by the rectangular sliding sleeve 603 and the two L-shaped hook rods 601 to drive the two locking holes 602 to be locked onto the corresponding locking rods 103 for positioning. The two L-shaped hook rods 601 continue to move upward and drive the receiving box 1 to the metal sheet leveling machine discharge port conveyor 100 to continue to receive materials smoothly. This makes it convenient to remove and replace the receiving box 1 when it is full, without the need for personnel to lift it, which facilitates the discharge and unloading work and makes it convenient for personnel to use.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
