Description

Technical Field

[0001] This utility model relates to the field of box gluing machines, specifically to a paper feeding mechanism for a box gluing machine. Background Technology

[0002] Chinese invention patent authorization announcement number CN 210062161 U discloses a feeding drive device for a gluing machine. The structure includes a paper feeding conveyor table and a paper feeding conveyor roller rotatably connected to the paper feeding conveyor table, a paper feeding conveyor belt wound between two paper feeding conveyor rollers, a paper feeding motor fixed on the paper feeding conveyor table to drive the paper feeding conveyor rollers to rotate, and a feeding plate disposed on the paper feeding conveyor table and perpendicular to the paper feeding conveyor belt. A gap is left between the bottom of the feeding plate and the paper feeding conveyor belt for a single sheet of cardboard to pass through. The device is characterized in that: a support conveyor roller for supporting the cardboard and a conveyor motor for driving the support conveyor roller to rotate are rotatably connected to the paper feeding conveyor table. The support conveyor roller is located above the paper feeding conveyor belt and below the cardboard stack. When the conveyor motor drives the support conveyor roller to rotate, it can push the cardboard at the bottom of the cardboard stack through the gap. A pressing roller for pressing the cardboard onto the paper feeding conveyor belt is rotatably connected to the side of the feeding plate away from the support conveyor roller. The pressing rollers can press the cardboard onto the paper conveyor belt, which helps to further improve the stability of the cardboard conveying.

[0003] The aforementioned mechanism has the following problem: after changing to different paperboards, the feed plate and pressing rollers need to be adjusted in height and position according to the thickness of the paperboard to adapt to the new paperboard thickness. This is necessary to ensure that the paperboard is conveyed more reliably and stably. In addition, the position of the paper feeding conveyor belt also needs to be adjusted according to the paperboard specifications. However, the relevant adjustment structure is not disclosed in the background technology, which means that the pressing rollers and feed plate need to be adjusted by cumbersome operations, which greatly affects the production efficiency. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a paper feeding mechanism for a gluing machine that is easy to adjust according to the specifications and thickness of the cardboard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding mechanism for a box gluing machine, including a frame, a belt arranged around the frame, a blade and a pressing roller arranged above the belt, a sliding block that slides left and right on the frame, a lifting block that can be raised and lowered on the sliding block, the blade and the pressing roller being installed on the lifting block, the blade and the pressing roller being adjusted up and down by their own adjustment structure, and the lower end of the blade pressing down or contacting the surface of the belt.

[0006] A support plate is mounted on the slide block, and a cylinder is installed on the support plate. The piston rod of the cylinder is connected to the lifting block.

[0007] The adjustment structure corresponding to the blade plate is a first fine-tuning knob, and the adjustment structure corresponding to the pressing roller is a second fine-tuning knob. The first fine-tuning knob controls the lifting and lowering adjustment of the blade plate, and the second fine-tuning knob controls the lifting and lowering adjustment of the pressing roller. The first and second fine-tuning knobs are rotatably mounted on a fixed plate. The upper ends of the first and second fine-tuning knobs are rotatably connected to the lifting block via pull shafts. A vertical mounting plate is provided on the slide block, and a guide is provided on the vertical mounting plate. The guide rail has a slider that slides along it. A blade is connected to the slider, and the upper end of the blade is connected to a rotatable first screw. The first screw is threadedly connected to the inner hole of the first fine-tuning knob. The pressing roller is mounted on a bracket, and a guide block is provided on the bracket. A groove is provided on the vertical mounting plate for the guide block to slide vertically. The guide block slides up and down in the groove. A rotatable second screw is connected to the guide block, and the screw is threadedly connected to the inner hole of the second fine-tuning knob.

[0008] The end wall of the blade near the belt is arc-shaped. When the end face of the blade presses down on the belt, the end face of the blade presses down on the end face of the belt by 0.03mm-0.05mm.

[0009] The beneficial effects of this utility model are: the blade and the pressing roller can be adjusted up and down separately through their respective adjustment structures, and can also be raised and lowered together by the lifting block. This greatly improves the efficiency of adjusting the position of the blade and the pressing roller. At the same time, during the conveyor belt process, as the lower end of the blade presses down or contacts the surface of the belt, the cardboard passes through the end of the blade through the friction and elasticity of the belt, avoiding multiple cardboard pieces passing through the blade. This achieves the technical effect of convenient adjustment according to the specifications and thickness of the cardboard, and effectively improves the debugging efficiency.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0014] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] like Figure 1 — Figure 3 As shown, this embodiment discloses a paper feeding mechanism for a gluing machine, including a frame 1. A belt 2 is arranged around the frame 1. The belt 2 is mounted on a horizontally movable support 3. The support 3 is equipped with a pulley with the belt and a motor that drives the pulley to rotate. The support 3 is driven by a linear motion module (the linear motion module performs linear motion through a gear and rack mechanism) to move horizontally left and right. A blade 4 and a pressing roller 5 are arranged above the belt 2. A sliding block 6 is installed on the frame 1. The sliding block 6 is mounted on a horizontal guide rail 13 and a guide rod to slide horizontally left and right. A lifting block 7 is arranged on the sliding block 6. The blade 4 and the pressing roller 5 are mounted on the lifting block 7. The blade 4 and the pressing roller 5 are adjusted up and down by their own adjustment structure. The lower end of the blade 4 presses down or contacts the surface of the belt 2.

[0016] A support plate 61 is mounted on the slide block 6, and a cylinder 8 is installed on the support plate 61. The piston rod of the cylinder 8 is connected to the lifting block 7. The cylinder 8 can simultaneously drive the blade plate 4 and the pressing roller 5 to move up and down by a certain stroke, effectively improving the adjustment efficiency.

[0017] The adjustment structure corresponding to the blade 4 is a first fine-tuning knob 9, and the adjustment structure corresponding to the pressing roller 5 is a second fine-tuning knob 10. The first fine-tuning knob 9 controls the lifting and lowering adjustment of the blade 4, and the second fine-tuning knob 10 controls the lifting and lowering adjustment of the pressing roller 5. The first fine-tuning knob 9 and the second fine-tuning knob 10 are rotatably mounted on a fixed plate 11. The upper ends of the first fine-tuning knob 9 and the upper ends of the second fine-tuning knob 10 are rotatably connected to the lifting block 7 via pull shafts. A vertical mounting plate 12 is provided on the slide 6, and a guide rail 13 is provided on the vertical mounting plate 12. A slider is mounted on the 3-axis, along which a blade 4 is connected. The upper end of the blade 4 is connected to a rotatable first screw 14, which is threadedly connected to the inner hole of a first fine-tuning knob 9. Multiple pressing rollers 5 are arranged sequentially and mounted together on a bracket 15. A guide block 151 is provided on the bracket 15. A groove is provided on the vertical mounting plate 12 for the guide block 151 to slide vertically. The guide block 151 slides up and down within the groove. A rotatable second screw 16 is connected to the guide block 151, which is threadedly connected to the inner hole of a second fine-tuning knob 10. Thus, manually rotating the first fine-tuning knob 9 or the second fine-tuning knob 10 can fine-tune the lifting position of the blade 4 and the pressing rollers 5, thereby adapting to the specifications and thickness of the cardboard.

[0018] The end wall of the blade 4 near the belt 2 is arc-shaped 41 for guiding the cardboard. One side of the stacked cardboard will be guided between the belt 2 and the blade 4 by the belt 2 against the arc 41. When the end face of the blade 4 presses down on the belt 2, the end face of the blade 4 presses down 0.03mm-0.05mm past the end face of the belt 2. This allows the cardboard to compress the belt 2 along the arc 41 of the blade 4 through the friction with the belt 2, so that it can pass through the lower end face of the blade 4 independently, avoiding the passage of multiple support plates 61, and making the transmission stability of the cardboard better.

[0019] Using the above technical solution, the blade 4 and the pressing roller 5 can be adjusted up and down respectively through their respective adjustment structures, and can also be raised and lowered together by the lifting block 7 for large stroke adjustment. This greatly improves the efficiency of position adjustment of the blade 4 and the pressing roller 5. At the same time, during the conveying of the cardboard along the belt 2, because the lower end of the blade 4 presses down or contacts the surface of the belt 2, the cardboard passes through the end of the blade 4 through the friction and elasticity with the belt 2, avoiding multiple cardboard pieces passing through the blade 4. This achieves the technical effect of convenient adjustment according to the cardboard specifications and thickness, and effectively improves the debugging efficiency.
