Description

Technical Field

[0002] In the production process of signboard plates, efficient cutting of metal plates is crucial. Traditional cutting methods often require using cutting tools to cut the metal plates multiple times, which increases the complexity of the operation and affects work efficiency.

[0003] The Chinese invention patent application number CN202410087676.2 discloses a one-time cutting and forming device for signboards, comprising a table top, on which a rack is provided for the movement of a cutting mechanism, which is used to support and guide the cutting mechanism, and symmetrically provided with circular end portions at both ends of the transverse section in the middle of the rack; the present invention overcomes the shortcomings of the prior art, has a reasonable design and a compact structure, and the cutting mechanism moves along the rack, first cutting the metal plate to be cut transversely, and then cutting from the front end of the metal plate to be cut.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Refer to the attached Figure 1-8 A plate cutting device for manufacturing signboards includes a first conveying mechanism 1 and a second conveying mechanism 2. The first conveying mechanism 1 and the second conveying mechanism 2 are provided with belts or several arranged rollers to convey the plates. The specific drive thereof belongs to the existing technology and will not be described in detail in this application.

[0033] A guide rail 3 for the cutting mechanism to slide is provided between the first conveying mechanism 1 and the second conveying mechanism 2. The cutting mechanism slides along the guide rail 3 so that the cutting mechanism can cut the plate between the first conveying mechanism 1 and the second conveying mechanism 2. The driving of the cutting mechanism to slide on the guide rail 3 belongs to the prior art and will not be elaborated in this application.

[0034] The bottom of the second conveying mechanism 2 is provided with a rotating column 21 that can drive it to rotate. The bottom of the rotating column 21 is rotatably connected to a sliding plate 22. The outer edge of at least one side of the first conveying mechanism 1 does not exceed the outer edge of the second conveying mechanism 2, so as to leave a path for the cutting mechanism to cut along this side. When in use, the cutting mechanism moves along the guide rail 3 to cut the plate between the first conveying mechanism 1 and the second conveying mechanism 2, and cuts the plate into two ends. Then, the sliding plate 22 is moved so that the second conveying mechanism 2 is away from the first conveying mechanism 1 to prevent the plate on it from hitting the second conveying mechanism 2 when the first conveying mechanism 1 rotates. The second conveying mechanism 2 is rotated 90° by rotating the rotating column 21, and then the sliding plate 22 is moved again so that the plate on the sliding plate 22 moves to the cutting path of the cutting mechanism. Finally, the cutting mechanism resets and cuts the other side of the plate on the second conveying mechanism 2. The two adjacent side walls of the plate are cut by the reciprocating motion of the cutting mechanism to complete the cutting of the plate, which greatly shortens the stroke of the entire cutting process, not only reduces the cutting energy consumption, but also improves the cutting efficiency.

[0035] A limit piece 23 is provided on the outer wall of the rotating column 21, and a collar 24 is provided on the top of the sliding plate 22. The collar 24 is sleeved on the outer wall of the rotating column 21, and the two are connected for relative rotation. A pair of limit posts 25 are provided on the top of the collar 24. The pair of limit posts 25 are respectively arranged on both sides of the extension arm of the limit piece 23 to constitute a mechanical limit structure for rotating the rotating column 21 90°. When the cutting mechanism cuts the plate for the first time, the extension arm of the limit piece 23 will abut against one side of one of the limit posts 25, which can prevent the rotating column 21 and the first conveying mechanism 1 from rotating. When the cutting mechanism cuts the plate for the second time, the limit piece 23 will follow the rotating column 21 to rotate 90°. At this time, the extension arm of the rotating column 21 will abut against one side of the other limit post 25, which can prevent the plate from rotating when the plate is cut for the second time, thereby greatly improving the cutting accuracy.

[0036] A support arm 51 is provided on one side of the second conveying mechanism 2, and a second cylinder 52 is provided on the support arm 51. A pressure plate 53 is provided at the bottom of the second cylinder 52. The pressure plate 53 is correspondingly arranged above the second conveying mechanism 2 to position the plate on the second conveying mechanism 2. When the plate moves onto the second conveying mechanism 2, the second cylinder 52 is started. At this time, the pressure plate 53 moves downward and squeezes the top of the plate, so that the plate is fixed on the second conveying mechanism 2, avoiding the movement of the plate relative to the second conveying mechanism 2 during cutting to affect the cutting accuracy.

[0037] A support plate 6 is provided at the bottom of the second conveying mechanism 2, and a slide groove 7 is provided on the top of the support plate 6 for the sliding plate 22 to slide away from the first conveying mechanism 1. The limiting member 23 includes a pair of extension arms, and the two extension arms are symmetrically arranged along the center of the limiting member 23. A pair of liftable lifting columns 8 are provided in the support plate 6. Initially, one of the lifting columns 8 remains above the support plate 6, and the top of the other remains lower than the extension arm. The lifting column 8 can be lifted and lowered along the inside of the support plate 6. A pair of lifting columns 8 are arranged on both sides of the sliding route of the sliding plate 22, and the lifting columns 8 are located on the route of the movement of the extension arm to limit the extension arm. After the first cutting of the plate is completed, the sliding plate 22 moves with the second conveying mechanism 2 away from the first conveying mechanism 1. During this process, the extension arm of the limiting member 23 will be blocked by one of the lifting columns 8. , and the rotating column 21 drives the second conveying mechanism 2 to rotate 90°. At this time, one side of the extension arm of the limit member 23 will touch one side of the limit column 25 to ensure the accuracy of the rotation of the second conveying mechanism 2. Then the sliding plate 22 is controlled to move the second conveying mechanism 2 toward the first conveying mechanism 1 to a suitable position, and then the cutting mechanism is controlled to cut the plate twice. After the cutting is completed, the lifting columns 8 on both sides are controlled to perform lifting movements, so that the lifting column 8 whose top was originally higher than the top of the extension arm moves downward, and the lifting column 8 whose top was previously lower than the top of the extension arm moves upward, and then the sliding plate 22 is controlled to reciprocate again. At this time, with the cooperation of the lifting column 8 and the extension arm, the second conveying mechanism 2 will rotate 90° in the opposite direction to realize the rotational reset of the second conveying mechanism 2, so as to facilitate subsequent continuous cutting work.

[0038] A slot plate 91 is provided at the bottom of the support plate 6, and a pusher 92 is slidably connected to the slot plate 91. The pusher 92 is arranged below the lifting column 8. The pusher 92 reciprocates along the slot plate 91 to push the lifting columns 8 on both sides upward respectively. When the pusher 92 moves along the slot plate 91, it can push different lifting columns 8 upward respectively, so as to control the lifting and lowering of the lifting column 8. The control is simple and convenient without the need for multiple drives.

[0039] The pushing piece 92 includes a U-shaped plate 921, and inclined plates 922 for cooperating with the lifting column 8 are symmetrically arranged on both sides of the U-shaped plate 921. The bottom of the inclined plate 922 is provided with a horizontal plate 923 for sliding in the groove plate 91. A rotatable cam 93 is provided in the middle of the U-shaped plate 921 to push the pushing piece 92 to slide in the groove plate 91. The control cabinet cam 93 rotates 180° inside the U-shaped plate 921. At this time, the inner wall of the other side of the U-shaped plate 921 is pushed by the cam 93, so that the pushing piece 92 moves along the groove plate 91. At this time, the pushing piece 92 will push the lifting column 8 on its moving direction side to move upward, and the lifting column 8 on the other side will move downward under its own gravity, which is convenient for controlling the lifting and lowering movements of the lifting columns 8 on both sides.

[0040] The bottom of the sliding plate 22 is fixedly connected to a tooth plate 221, and a plurality of equidistantly arranged receiving grooves 222 are opened in the tooth plate 221, and a ratchet 223 is rotatably connected in the receiving groove 222. One side of the ratchet 223 is connected to the inner wall of the receiving groove 222 by a supporting spring 224. A ratchet 94 is provided on the top of the cam 93, which cooperates with the ratchet 223 to drive the cam 93 to rotate. When the sliding plate 22 moves along the slide groove 7 away from the first conveying mechanism 1, the tooth plate 221 follows the sliding plate 22 to move, and the ratchet 223 contacts the ratchet 94 and is squeezed by the outer teeth of the ratchet 94 to rotate in the receiving groove 222. Then, when the sliding plate 22 moves toward the first conveying mechanism 1, the ratchet 223 is hooked on the outer teeth of the ratchet 94 and drives the ratchet 94 to rotate. After being pulled by several ratchets 223, the ratchet 94 drives the cam 93 to rotate 180 degrees to control the lifting movement of the lifting columns 8 on both sides, which is convenient for the subsequent rotation and reset of the second conveying mechanism 2.

[0041] A first cylinder 10 is provided in the chute 7, and the output end of the first cylinder 10 is connected to the sliding plate 22. When the first cylinder 10 is started, the first cylinder 10 can drive the sliding plate 22 to reciprocate in the chute 7, thereby realizing the movement of the second conveying mechanism 2 away from or close to the first conveying mechanism 1.

[0042] The cutting mechanism includes a slider 41 that can slide along the guide rail 3. A pair of vertical rods 42 are provided on the top of the slider 41. The outer walls of the pair of vertical rods 42 are slidably connected to a shock-absorbing plate 43. The bottom of the shock-absorbing plate 43 is connected to the top of the slider 41 through a shock-absorbing spring 44. A motor 45 is provided on the shock-absorbing plate 43. The output end of the motor 45 is connected to a cutting blade 46. The cutting blade 46 is located between the first conveying mechanism 1 and the second conveying mechanism 2 to cut the plates of the two parts. The shock-absorbing spring 44 absorbs vibrations during the cutting process to prevent the cutting blade 46 from being deflected due to vibration, thereby ensuring a smooth incision. The sliding cooperation between the vertical rods 42 and the shock-absorbing plate 43 further disperses vibration energy and extends the service life of the equipment.

[0043] Furthermore, the cutting mechanism is not limited to using the cutting blade 46 for cutting, and can also be a laser cutting machine.

[0044] Working principle: the plate is transported to the appropriate position through the first conveying mechanism 1 and the second conveying mechanism 2, and then the cutting mechanism is controlled to slide on the guide rail 3. During this process, the cutting mechanism cuts the plate and cuts the plate into two parts. Then the first cylinder 10 is started to control the sliding plate 22 to move along the slide 7 away from the first conveying mechanism 1. During this process, with the cooperation of the limiter 23 and the lifting column 8, the rotating column 21 will drive the first conveying mechanism 1 to rotate 90°, and then the sliding plate 22 is controlled by the first cylinder 10 to move along the slide 7 to the first conveying mechanism 1 to the appropriate position, and then the cutting mechanism is controlled to perform a reset movement on the guide rail 3. At this time, the cutting mechanism will cut the other adjacent side wall of the plate on the second conveying mechanism 2. The reciprocating motion of the cutting mechanism can complete the cutting of the two adjacent sides of the plate, shortening the stroke of the entire cutting process, reducing cutting energy consumption, and improving cutting efficiency.

[0045] When the first cylinder 10 controls the sliding plate 22 to move along the slide groove 7 toward the first conveying mechanism 1, the ratchet 223 drives the ratchet 94 to rotate, further causing the cam 93 to rotate 180°. At this time, the lifting column 8 on the other side moves upward, and the lifting column 8 that initially contacts the limit member 23 moves downward under the action of its own gravity. When the plate is cut twice, the sliding plate 22 is controlled to reciprocate in the slide groove 7 again. When the sliding plate 22 moves away from the first conveying mechanism 1, under the action of the lifting column 8 and the limit member 23, the rotating column 21 drives the second conveying mechanism 2 to rotate 90° in the opposite direction. When the sliding plate 22 moves toward the first conveying mechanism 1, with the cooperation of the ratchet 223 and the ratchet 94, the lifting columns 8 on both sides perform lifting movements respectively, so that the entire device returns to its initial state, which is convenient for subsequent continuous cutting operations.
