[0030] 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.

[0031] Example 1, such as Figures 1-3 The present invention provides the following technical solution to address the problem of inconvenient waste collection in the device: a recycling mechanism is disclosed.

[0032] The base includes a base 1, with a conveying mechanism 2 connected to its inner side. A drive mechanism 3 is mounted on the other side of the base 1 near the conveying mechanism 2. A cutter holder 4 is fixed to the side of the drive mechanism 3 near the conveying mechanism 2. The conveying mechanism 2 includes two rotating rollers and a transmission belt, with the transmission belt located between the two rollers. A first collection box 101 is located on the left side of the base 1, with rollers mounted on its bottom. A first fixing block 102 is symmetrically fixed to the inner side of the base 1 near the first collection box 101, and a second collection box 10 is connected to the top of the first fixing block 102. 3. A recycling mechanism for collecting waste is provided on the side of the base 1. An external block 111 is fixed on the side of the base 1 near the first fixed block 102. A swing mechanism for improving the waste recycling effect is provided on the side of the external block 111. The recycling mechanism includes a cleaning brush 104. The cleaning brush 104 is connected inside the second collection box 103. The cleaning brush 104 is in close contact with the transmission belt. Telescopic blocks 105 are symmetrically fixed on the side of the cleaning brush 104. The telescopic blocks 105 slide through the telescopic groove 106. A spring is telescopically connected between the telescopic groove 106 and the telescopic blocks 105.

[0033] The printing of circuit boards involves multiple steps, such as copper foil bonding, circuit pattern etching, and surface treatment. After the copper foil of the circuit board is bonded, it needs to be placed on the conveyor belt of the conveyor mechanism 2 for conveying and cutting. The conveyor belt can transport the circuit board directly below the cutter holder 4. The cutter holder 4 will press down through the operation of the drive mechanism 3, thereby cutting off the excess copper foil protruding from the circuit board. After the copper foil is cut off, the worker removes the circuit board, and the waste on the surface of the conveyor belt will fall into the first collection box 101 through the conveyor. At the same time, the conveyor belt will rub against the cleaning brush 104 during the conveying process. The spring can push the telescopic block 105 upward through its own elastic thrust. When the telescopic block 105 moves, it can slide through the telescopic groove 106. When the telescopic block 105 slides upward, it can drive the cleaning brush 104 to stick tightly to the conveyor belt of the conveyor mechanism 2. After the conveyor belt is pressed tightly, the residual adsorbed waste residue on the surface can fall into the second collection box 103 for collection, which improves the waste collection efficiency of the device.

[0034] Example 2, as follows Figure 2 and Figure 4 The present invention provides the following technical solution to address the problem that the second collection box 103 for collecting waste is inconvenient to install, thus affecting the waste processing efficiency. Based on Embodiment 1, a sliding mechanism is disclosed:

[0035] The bottom of the second collection box 103 is equipped with a sliding mechanism for easy material discharge. The sliding mechanism includes a first sliding block 107, which is connected to the upper surface of the first fixed block 102. A T-shaped block 108 slides through the first sliding block 107. The T-shaped blocks 108 are fixed to the bottom of the second collection box 103, and four T-shaped blocks 108 are symmetrically fixed to the bottom of the second collection box 103. A spring piece 109 is fixed to the bottom of two symmetrical T-shaped blocks 108. The spring piece 109 is positioned inside the positioning groove 110, which is opened inside the first sliding block 107. The second collection box 103 of the device needs to be installed before use. When installing the second collection box 103, the T-shaped blocks 107 need to be moved. The T-shaped block 108 moves to the end of the groove of the first sliding block 107 and inserts itself. When the T-shaped block 108 is inserted, it can slide through the first sliding block 107. When the T-shaped block 108 slides, it can drive the spring piece 109 to press against the inner wall of the groove of the first sliding block 107. When the spring piece 109 is pressed, it can deform through its own material. When the spring piece 109 deforms, it can move to the side of the positioning groove 110. At this time, the spring piece 109 can be reset through its own material. When the spring piece 109 is reset, it can be positioned through the positioning groove 110. When the spring piece 109 is positioned, it can drive the second collection box 103 to be positioned. In this way, the installation of the second collection box 103 is realized, which improves the convenience of using the device.

[0036] Example 3, as follows Figure 1 , Figure 5 , Figure 6 and Figure 7 The present invention provides the following technical solution to address the problem of insufficient waste collection during copper foil cutting in printing equipment: Based on Embodiment 1, a swing mechanism is disclosed:

[0037] The swing mechanism includes a second fixed block 114, which is fixed to the side of the first collection box 101 near the base 1. A rotating rod 113 is rotatably connected to the inner side of the second fixed block 114. A first rotating block 112 is rotatably connected to the side of the rotating rod 113 away from the second fixed block 114. The first rotating block 112 is fixed to the output end of the motor. The motor is mounted on the side of the outer block 111. A second rotating block 115 is fixed to the side of the first rotating block 112 away from the motor. A pressing block 116 is fixed to the side of the second rotating block 115 away from the first rotating block 112. The pressing block 116 slides through the inside of the connecting block 117. The connecting block 117 is fixed to the bottom of the second collection box 103. A second sliding block 118 is symmetrically fixed to the bottom of the first sliding block 107. The second sliding block 118 slides through the inside of the slide groove 119. The slide groove 119 is opened at the top of the first fixed block 102.

[0038] After a period of time, waste materials accumulate in some areas. When the motor is started, its output drives the first rotating block 112 to rotate. This rotation pulls the rotating rod 113, which in turn rotates the second fixed block 114. The second fixed block 114 moves due to the rotation of the rotating rod 113, pulling the first collection box 101. The first collection box 101 moves by rolling on its bottom rollers, which reduce friction and increase smoothness. Simultaneously, the rotation of the first rotating block 112 drives the second rotating block 115 to rotate, which in turn drives the compression block 1... When the extrusion block 116 rotates, it can extrude force on the inner wall of the connecting block 117. At the same time, the extrusion block 116 can slide through the inside of the connecting block 117. When the connecting block 117 is extruded, it can drive the second collection box 103 to move. When the second collection box 103 moves, it can drive the second sliding block 118 to move through the first sliding block 107. When the second sliding block 118 moves, it can slide through the slide groove 119, thus realizing the sliding of the second collection box 103. Since the first rotating block 112 rotates continuously, the first collection box 101 and the second collection box 103 will swing back and forth continuously. Through repeated swinging, the waste and slag inside the first collection box 101 and the second collection box 103 can be evenly distributed, improving the waste collection effect of the device.

[0039] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
