Technical Field

[0001] This application relates to the field of sign processing technology, and in particular to a sign cutting device. Background Technology

[0002] Signage, as the name suggests, is a sign used to indicate directions and provide warnings. Common types of signage include public service signs, cultural signs, directional signs, and warning signs. In the production process of signage, it is often necessary to cut the signage to the required size. Therefore, cutting equipment is required. However, existing cutting equipment can only cut signage. During the cutting process, many people hold the signage to hold it in place, but the stability is poor and it is easy for the signage to move. This results in the signage not being cut accurately, and if not careful, the cutting equipment can injure the workers' hands, leading to safety accidents. Utility Model Content

[0003] To address the issue that multiple people hold the sign for support during the cutting process, but the stability is poor and the sign is prone to movement, resulting in inaccurate cutting and the risk of injury to workers' hands if not careful, this application provides a sign cutting device.

[0004] The sign cutting device provided in this application adopts the following technical solution:

[0005] A sign cutting device includes a rectangular frame, a sliding plate, and a connecting rod. The sliding plate slides above the rectangular frame via a guide. A cutting component is provided at the top of the sliding plate. Supports are fixedly installed at the four corners of the top of the rectangular frame. A clamping plate slides inside the rectangular frame. Both ends of the connecting rod movably pass through the rectangular frame and are welded to one side of the clamping plate. A circular hole is provided on one side of the connecting rod, and a nut is welded to the other side of the connecting rod, communicating with the circular hole. A bolt is threaded through the internal thread of the nut and movably passes through the circular hole. A limiting component for limiting the bolt is provided on one side of the rectangular frame.

[0006] Preferably, the guide member consists of two fixed rods and two fixed posts. The two fixed rods are respectively welded to the two ends of the top of the rectangular frame, and the two ends of the two fixed posts are respectively welded to the two ends of the two fixed rods. The two ends of the sliding plate are respectively movably sleeved on the outer surface of the two fixed posts.

[0007] Preferably, the cutting element consists of a motor and a cutting blade. The motor is fixedly mounted on the top of the sliding plate by four screws, and the cutting blade is mounted on the end of the motor's power shaft by a connector.

[0008] Preferably, the connector consists of a connecting piece, a support block, a threaded post, and a second nut. The connecting piece is welded to the end of the motor drive shaft, the support block is welded to one side of the connecting piece, the threaded post is welded to one side of the support block, the cutting blade is sleeved on the outer surface of the support block, and the second nut is threadedly sleeved on the outer surface of the threaded post. One side of the second nut abuts against one side of the cutting blade.

[0009] Preferably, the limiting component consists of a fixed cap and a rotating block. The fixed cap is welded to one side of the rectangular frame, the rotating block is movably placed inside the fixed cap, one end of the bolt movably passes through the fixed cap, and one end of the bolt is welded to one side of the rotating block.

[0010] Preferably, a fixing block is welded to one end of the top of the sliding plate, and a handle is welded to one side of the fixing block.

[0011] In summary, this application includes the following beneficial technical effects: by rotating the bolt, the bolt applies a helical thrust to the nut during rotation, causing the nut to move the connecting rod. The connecting rod then moves the clamping plate and abuts against one side of the sign, while the other side of the sign abuts against the inner wall of the rectangular frame, thus limiting the sign's position. In this way, the sign can be fixed during the cutting process using the cutting component, eliminating the need for manual support and fixation, resulting in high safety. Attached Figure Description

[0017] The following is combined with Figure 1 -Appendix Figure 4 This application is described in further detail.

[0018] Example 1:

[0019] A sign cutting device, as shown in the reference Figure 1-4The system includes a rectangular frame 1, a sliding plate 3, and a connecting rod 52. The sliding plate 3 slides above the rectangular frame 1 via a guide member 4. The guide member 4 consists of two fixed rods 41 and two fixed posts 42. The two fixed rods 41 are welded to the two ends of the top of the rectangular frame 1, and the two ends of the two fixed posts 42 are welded to the two ends of the two fixed rods 41, respectively. The two ends of the sliding plate 3 are movably sleeved on the outer surfaces of the two fixed posts 42, thus limiting the sliding plate 3 so that it can only move linearly at the top of the rectangular frame 1. A cutting component 7 is provided at the top of the sliding plate 3. The cutting component 7 consists of a motor 71 and a cutting blade 72. The motor 71 is fixedly mounted on the top of the sliding plate 3 by four screws. The motor 71 is electrically connected to an external power supply through an external switch. The motor 71 is preferably a YE2132M-4 type. The cutting blade 72 is mounted on the end of the motor 71's drive shaft through a connector 8. The connector 8 consists of a connecting piece 81, a support block 82, a threaded post 83, and a nut 84. The connecting piece 81 is welded to the end of the motor 71's drive shaft, and the support block 84... 2. Welded to one side of the connecting piece 81, the threaded post 83 is welded to one side of the support block 82, the cutting piece 72 is sleeved on the outer surface of the support block 82, and one side of the cutting piece 72 abuts against one side of the connecting piece 81. The second nut 84 is threadedly sleeved on the outer surface of the threaded post 83, and one side of the second nut 84 abuts against one side of the cutting piece 72, which can fix the cutting piece 72 to the power shaft of the motor 71. The four corners of the top of the rectangular frame 1 are fixedly installed with support feet 2 to support the rectangular frame 1. The inside of the rectangular frame 1 has a sliding clamp. A clamping plate 51 is used, with its top and bottom surfaces respectively fitting against the inner top and bottom walls of the rectangular frame 1. Both ends of a connecting rod 52 movably penetrate the rectangular frame 1 and are welded to one side of the clamping plate 51. A circular hole is provided on one side of the connecting rod 52, and a nut 53 is welded to the other side of the connecting rod 52. The nut 53 communicates with the circular hole, and a bolt 54 passes through the internal thread of the nut 53. The bolt 54 is self-locking. The self-locking condition depends on the thread helix angle, the coefficient of friction, and the load applied. The self-locking condition can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking.The above content refers to existing technology. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here. Bolt 54 moves through the circular hole. A limiting member 6 for limiting bolt 54 is provided on one side of the rectangular frame 1. The limiting member 6 consists of a fixing cap 61 and a rotating block 62. The fixing cap 61 is welded to one side of the rectangular frame 1, and the rotating block 62 is movably placed inside the fixing cap 61. One end of bolt 54 moves through the fixing cap 61, and the other end of bolt 54 is welded to one side of the rotating block 62. In this way, bolt 54 can rotate on one side of the rectangular frame 1. Then, the sign is inserted through the rectangular frame 1, and bolt 54 is rotated. During the rotation, a helical thrust is applied to nut 53, causing nut 53 to move connecting rod 52. Connecting rod 52 moves clamping plate 51 and it comes into contact with one side of the sign. At the same time, the other side of the sign comes into contact with the inner wall of rectangular frame 1. This limits the position of the sign. A fixing block 91 is welded to one end of the top of sliding plate 3, and a handle 92 is welded to one side of fixing block 91. Then, motor 71 is started. The power shaft of motor 71 drives cutting blade 72 to rotate. At the same time, the hand holds the handle 92 and pulls sliding plate 3 to move. During the movement of sliding plate 3, motor 71 and cutting blade 72 can be moved to cut the sign.
