DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1: Figure 1 , Figure 2 , Figure 4 , Fig. 9 and Fig.10 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the punching machine is unstable when conveying the product box, which easily affects the quality of the product box, a sliding mechanism is disclosed:

[0040] The base frame 1 includes a machine housing 2 connected to the upper surface of the base frame 1, a closing door 3 connected to the side of the machine housing 2, a linear guide rail 102 symmetrically fixed to the inner side of the base frame 1, a slide rail 103 sliding on the surface of the linear guide rail 102, a moving frame 104 connected to the side of the slide rail 103 away from the base frame 1, four groups of slide rails 103 are connected to the bottom of the moving frame 104, two first plates 105 are symmetrically installed on the top of the moving frame 104, a sliding mechanism for improving the stability of the punching machine in conveying workpieces is connected to the inner side of the base frame 1, a fixing rod 112 is connected to one side of the first plate 105, a placement mechanism for improving the efficiency of placing the product box is arranged on the top of the fixing rod 112, and a guide rail 103 is fixed to the other side of the first plate 105. Toward rod 115, a lifting mechanism for improving the efficiency of the upper and lower product boxes of the punching machine is arranged on the side of the first platen 105, and the sliding mechanism includes a second platen 106, and the second platen 106 is connected to the upper surface of the first platen 105. A first servo motor 107 is installed at the bottom of the mobile frame 104, and a reducer 108 is installed on one side of the first servo motor 107. The first servo motor 107 is connected to the two sides of the reducer 108. The driving shaft 109 is fixed to the output end of the first servo motor 107, and the end of the driving shaft 109 is connected to a gear 110, and the gear 110 is meshed and connected to the upper surface of the rack 111, and the rack 111 is fixed to the side of the base frame 1 close to the linear guide 102;

[0041] When the punching machine needs to convey the product box for processing, the first servo motor 107 is started. When the first servo motor 107 is started, the output end can rotate. When the first servo motor 107 rotates, the output end can drive the driving shaft 109 to run. When the first servo motor 107 runs, the reducer 108 will also run. The reducer 108 can increase the torque of the first servo motor 107 by changing the speed. When the torque of the first servo motor 107 increases, the driving shaft 109 can rotate stably. When the driving shaft 109 rotates, the gears 110 on both sides start to rotate. When the gears 110 rotate, they can be meshed and rotated through the racks 111.

A side plate 114 is fixed on the top of the bottom plate 113. There are four side plates 114, and a product box is arranged inside the side plate 114. The side plate 114 and the product box are closely connected. A hydraulic plate 123 is installed inside the machine housing 2. A suction device is connected to the bottom of the hydraulic plate 123. When the punching machine processes the product box, the first plate 105 is first driven to move by the sliding mechanism. When the first plate 105 moves, it can drive the second plate 106 on the top to move. When the second plate 106 moves, it can drive the fixing rod on the top. 112, the bottom plate 113 and the side plate 114 move, and the machine program will realize placing the processed product box inside the side plate 114 and the bottom plate 113. At this time, the side plate 114 and the bottom plate 113 can move the product box. After the product box moves to the bottom of the hydraulic plate 123 inside the machine housing 2, the hydraulic plate 123 can grab the product box through the suction device at the bottom. After the product is grabbed, it can be collected and stacked. When a certain number is stacked, it can be sent out for packaging. When the product box is placed between the bottom plate 113 and the side plate 114, no resistance or large shaking will be generated, which improves the accuracy of punching the product box and the efficiency of product placement and extraction.

[0044] Embodiment 3: Figure 4-Figure 10 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the product box of the punching machine is unstable when moving up and down, and is prone to position deviation, which affects the processing effect, a lifting mechanism is disclosed:

[0045] The lifting mechanism includes a threaded rod 116, which is fixed at the center of the second platform 106. A guide rod 115 is fixed at the bottom of the second platform 106 away from the threaded rod 116. Four groups of guide rods 115 are fixed. Limiting columns 117 are symmetrically fixed on the upper surface of the first platform 105. A second pulley 119 is installed on the top of the first platform 105 near the limiting column 117. The second pulley 119 is located at the center of the first platform 105. A through hole is opened at the center of the first platform 105. A rotating nut 124 is connected to the bottom of the second pulley 119. The rotating nut 124 is located on the side of the first platform 105 away from the second pulley 119. The rotating nut 124 moves synchronously with the second pulley 119. A threaded rod 116 is connected through the inside of 119 and the rotating nut 124, and the threaded rod 116 and the rotating nut 124 are threadedly connected. The upper surface of the first platen 105 near the second pulley 119 is rotatably connected with the first pulley 118, and a transmission belt 120 is connected between the first pulley 118 and the second pulley 119. The first pulley 118, the second pulley 119 and the transmission belt 120 are transmission connected. A guide cylinder 121 is connected through the inside of the first platen 105 near the first pulley 118, and the guide cylinder 121 is connected with four groups. The guide cylinder 121 and the guide rod 115 are slidably connected. The bottom of the first pulley 118 is connected to the output end of the second servo motor 122, and the second servo motor 122 is installed at the bottom of the side plate 114;

[0046] During the punching and stacking of the product boxes, the product boxes need to be lifted up and down. When the product boxes are lifted up and down, the second servo motor 122 is started. When the second servo motor 122 is started, the output end can drive the first pulley 118 to rotate. When the first pulley 118 rotates, the side can drive the transmission belt 120 to rotate. When the transmission belt 120 rotates, it can drive the second pulley 119 to rotate. When the second pulley 119 rotates, it can rotate on the surface of the first platen 105. When the second pulley 119 rotates, the bottom can drive the rotating nut 124 to rotate synchronously. When the rotating nut 124 rotates, it can drive the threaded rod 116 to slide. When the thread of the threaded rod 116 slides, it can push the thread of the first platen 105 to move upward. When the thread of the first platen 105 moves, it can drive the four guide rods 115 to move. When the four guide rods 115 move, they can slide through the four guide cylinders 121. When the guide rods 115 slide, the second platen 106 can In order to achieve upward movement, reverse starting of the second servo motor 122 can drive the second platform 106 to descend. When the second platform 106 slides downward through the thread of the threaded rod 116, the second platform 106 can move to the top of the limiting column 117 for positioning. The second platform 106 can be limited by the limiting column 117. At the same time, the limiting column 117 can generate a supporting force for the second platform 106, which improves stability and prevents the second platform 106 from colliding with parts on the surface of the first platform 105 and the product box from being damaged. When the second platform 106 moves upward, it can push the fixing rod 112 to move upward. When the fixing rod 112 moves upward, it can push the bottom plate 113 and the side plate 114 to move, thereby driving the product box to move upward. After the product box moves to the specified position, it can be processed and handled. Since the second platform 106 is guided and slid by four guide rods 115, the stability of the punching machine when lifting the product box is improved.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
