[0013] 1. The trimming device for paper box manufacturing is provided with a bidirectional screw, a movable seat, a clamping plate, a clamping spring and a guide plate, and the bidirectional screw is controlled to rotate so that the movable seat moves on the surface of the limit slide and the bidirectional screw. According to the size of the paper box, the two sets of guide plates are controlled to move closer to or farther away from each other and close to the two sides of the paper box. The two sets of clamping plates are lifted up to place the paper box on the top of the conveying roller at the bottom of the two sets of clamping plates. The clamping plates are released and pressed toward the movable seat under the rebound action of the clamping spring, so that the clamping plates can be pressed against the top of the paper box, ensuring that when the paper box is cut, the side of the paper box away from the cutting knife will not be lifted away from the conveying roller, thereby avoiding tilted cutting.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, the utility model provides a technical solution: a trimming device for paper box manufacturing, including a top frame 4, support columns 2 are fixedly installed at the four corners of the bottom of the top frame 4, a bottom plate 1 is fixedly installed at the bottom ends of four groups of support columns 2, and a collecting box 3 is provided on one side of the top of the bottom plate 1 at the bottom of the top frame 4. Due to the provision of the collecting box 3, the paper box waste cut by the cutting knife 9 falls into the collecting box 3 for centralized processing.

[0021] Electric push rods 5 are symmetrically fixedly installed on both sides of the collecting box 3 on the top of the bottom plate 1, and the top ends of the two groups of electric push rods 5 pass through the top frame 4 and are fixedly installed with mounting plates 6. Three groups of buffer rods 7 are equidistantly slidably installed on the bottom of the mounting plate 6, and mounting frames 8 are fixedly installed on the bottom ends of the three groups of buffer rods 7. By providing the electric push rods 5, the two groups of electric push rods 5 are controlled to extend and retract synchronously, driving the mounting plate 6 to approach or move away from the top frame 4, thereby controlling the cutting knife 9 to move up and down to cut the paper box.

[0022] A cutting knife 9 is provided at the bottom of the mounting frame 8, and the top end of the buffer rod 7 passes through the mounting plate 6 and is fixedly installed with a limiting plate 10, and a buffer spring 11 is provided on the surface of the buffer rod 7 between the mounting plate 6 and the mounting frame 8. Due to the buffer spring 11, when the cutting knife 9 contacts the hard cardboard box, the cutting knife 9 will push the mounting frame 8 toward the mounting plate 6, so that the buffer spring 11 is compressed and deformed between the mounting plate 6 and the mounting frame 8, thereby buffering the cutting of the hard cardboard box by the cutting knife 9.

[0023] A fixed plate 14 is symmetrically fixedly installed on one side of the top frame 4, and a limit slide bar 15 is fixedly installed between two groups of fixed plates 14 on the same side of the top frame 4. Support plates 16 are fixedly installed on both sides of the bottom of the top frame 4, and a bidirectional screw 17 is rotatably installed between the two groups of support plates 16. By providing the limit slide bar 15 and the bidirectional screw 17, the bidirectional screw 17 is controlled to rotate, so that the two groups of moving seats 18 are close to or away from each other on both sides of the bidirectional screw 17 and the limit slide bar 15, so as to facilitate the adjustment of the distance between the two groups of moving seats 18. At the same time, when the moving seat 18 moves on the surface of the limit slide bar 15, it is ensured that the moving seat 18 will not be tilted or deflected during the movement;

[0024] Both ends of the bidirectional screw 17 pass through the support plate 16 and are fixedly installed with locking studs 19, one end of the locking stud 19 is fixedly installed with a cross plate 21, and a locking screw sleeve 20 is provided on the surface of the locking stud 19. Because of the locking screw sleeve 20, after the movable seat 18 is adjusted according to the specifications of the paper box so that it can be close to both sides of the paper box, the locking screw sleeve 20 is tightened to lock and fix the locking stud 19 to ensure that the bidirectional screw 17 will not rotate at will.

[0025] A moving seat 18 is symmetrically slidably mounted on both sides of the surface of the bidirectional screw 17 and the two sets of limit slide bars 15; a guide plate 26 is fixedly mounted on one side of the top of the moving seat 18. By providing the guide plate 26, the paper box can move horizontally on the top of the conveying roller 13 after passing through the two sets of guide plates 26, and will not be tilted or deflected when passing through the bottom of the cutting knife 9;

[0026] The top of the movable seat 18 is symmetrically fixed with mounting columns 22, and pressure plates 23 are slidably installed on the surfaces of the two groups of mounting columns 22. Connecting strips 25 are fixedly installed on the tops of the two groups of mounting columns 22, and a pressure spring 24 is provided on the surface of the mounting columns 22 between the pressure plate 23 and the connecting strip 25. Because the pressure spring 24 is provided, the pressure plate 23 is pressed toward the movable seat 18 under the rebound action of the pressure spring 24, so that the pressure plate 23 can press the paper box on the top of the conveying roller 13 without tilting away from the conveying roller 13.

[0027] The top frame 4 is located between the two groups of limit slide bars 15 and has two groups of mounting shafts 12 fixedly installed on both sides. A conveying roller 13 is rotatably installed on the surface of the mounting shaft 12. By providing the conveying roller 13, when the paper box is pushed to move on the top of the conveying roller 13, the conveying roller 13 rolls under the friction between the paper box and the paper box, which facilitates the paper box to move on the top of the top frame 4.

[0028] The working principle of the utility model is:

[0029] The locking screw sleeve 20 is loosened, and the two sets of cross plates 21 are held to control the two-way screw 17 to rotate. The distance between the two sets of moving seats 18 is adjusted according to the specifications of the carton, so that the carton can be closely attached to the two sets of guide plates 26, and the locking screw sleeve 20 is tightened to lock and fix the two-way screw 17, and the two sets of pressing plates 23 are lifted up away from the conveying roller 13, and the carton is placed on the top of the conveying roller 13. After pushing the carton to move to the top of the two sets of pressing plates 23, the pressing plates 23 are loosened. Under the rebound action of the pressing spring 24, the pressing plates 23 can be pressed against the top of the carton, and the carton is pushed to move on the top of the conveying roller 13 until it is located at the bottom of the cutting knife 9, and the electric push rod 5 is controlled to contract and drive the mounting plate 6 to move downward, so that the cutting knife 9 is close to the carton for cutting. At the same time, the carton will lift the cutting knife 9, compress and deform the buffer spring 11, and buffer the cutting of the carton by the cutting knife 9, so that the cutting knife 9 can be close to the top of the carton.
