Description

Technical Field

[0001] The utility model relates to the field of folder gluing machines, in particular to an automatic feeding device for folder gluing machines. Background Art

[0002] In the packaging and printing industry, the application of the folder gluer is the last step in the packaging box processing. It is to fold the printed and die-cut cardboard into shape and glue the edges. The machine glues the box instead of the manual box gluer, reducing labor costs and improving efficiency. Some existing folder gluers have an ineffective positioning effect on the paper boxes, and the stacked paper boxes need to be transported to the processing station one by one.

[0003] The current automatic feeding device of the folder gluer, as described in the patent with announcement number CN219650670U, includes a workbench, a pushing mechanism, a limiting mechanism, an auxiliary conveying mechanism, a positioning mechanism and a conveyor belt; the upper surface of the workbench is divided into two areas on the left and the right, namely the preparation area on the right and the conveying area on the left; the preparation area is provided with a pushing mechanism for pushing the cardboard and a limiting mechanism for limiting the position of the stacked cardboard from right to left, the pushing mechanism includes a push plate and a cylinder for pushing the push plate, and the push plate is horizontally arranged on the upper surface of the workbench; the limiting mechanism includes two baffles arranged vertically on the left and right, and an adjusting component for adjusting the height of the two baffles is provided on the upper surface of the workbench, the cardboard is stacked between the two baffles, and a gap is left between the bottom end of the baffle and the upper surface of the workbench to facilitate the cardboard to pass through, the gap is greater than the thickness of one layer of cardboard and less than the thickness of two layers of cardboard, and the push plate is arranged opposite to the gap.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when supplying different cardboards, due to the difference in thickness of cardboards of different specifications, and the thickness of the push plate is fixed, if the thickness of the cardboard to be pushed is less than half the thickness of the push plate, the push plate will push two pieces of cardboard at a time, which is difficult to meet the subsequent box gluing needs, thereby causing the entire feeding device to have poor applicability.

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] See also Figure 1-4 An automatic feeding device for a box-gluing machine includes a conveying mechanism 1, the conveying mechanism 1 includes a conveying frame 101, a belt conveyor 102 is fixedly installed inside the conveying frame 101, and the belt conveyor 102 is set to convey the cardboard to be pasted when starting up, so as to realize the feeding of the box-gluing machine. The two sides of the conveying frame 101 are symmetrically fixedly connected due to guide plates 103, and the insides of the two groups of guide plates 103 are both rotatably connected with first adjusting screws 104, and the outer sides of the two groups of first adjusting screws 104 are threadedly connected with sliding beams 105. The first adjusting screws 104 can drive the sliding beams 105 to move up and down when starting up, so as to realize the height adjustment of the sliding beams 105. The outer sides of the two groups of first adjusting screws 104 are fixedly connected with worm gears 106, and the outer sides of the two groups of worm gears 106 are meshingly connected with gripping rods 107. The gripping rods 107 are rotatably connected to the two groups of guide plates 103. When the gripping rods 107 rotate, they can drive the worm gears 106 on both sides and the two groups of first adjusting screws 104 to rotate synchronously, thereby realizing synchronous adjustment of the worm gears 106.

[0027] Two moving beams 108 are slidably connected to the outer sides of the two sets of sliding beams 105. The setting of the sliding beams 105 can guide the sliding of the moving beams 108. The bottoms of the two sets of moving beams 108 are evenly rotated and connected with multiple rollers 110. The setting of the limit plate 111 can press the conveyed cardboard during the cardboard conveying process. The tops of the two sets of moving beams 108 are both threadedly connected with limit bolts 109. The two sets of limit bolts 109 are both in contact with the sliding beams 105. When the limit bolts 109 are rotated to contact with the sliding beams 105, they can limit the moving beams 108. One end of the two sets of moving beams 108 is fixedly connected to a limiting plate 111, which can limit one side of the cardboard. At the same time, when the first adjusting screw 104 rotates to drive the sliding beam 105 to move up and down, the moving beam 108 and the limiting plate 111 can be driven to move up and down accordingly, so that the distance between the limiting plate 111 and the belt conveyor 102 can be adjusted to be consistent with the thickness of the cardboard, so that the cardboard can pass under the limiting plate 111.

[0028] The tops of the two groups of moving beams 108 are fixedly connected with diagonal braces 112, and the two groups of diagonal braces 112 are respectively fixedly connected with the two groups of limit plates 111. The setting of the diagonal braces 112 can further connect and fix the moving beams 108 and the limit plates 111, thereby improving the installation stability of the limit plates 111.

The top wall of the bearing plate 201 is evenly and movably connected with a plurality of balls 202, and the top of the balls 202 is at the same height as the top of the belt conveyor 102. The setting of the balls 202 facilitates the movement of the cardboard on the top of the bearing plate 201. Guide grooves 203 are symmetrically provided on both sides of the carrier plate 201 , and side plates 204 are passed through the guide grooves 203 on both sides.

The two sets of reinforcing rib plates 205 are fixedly connected with the moving seat 207. The setting of the reinforcing rib plate 205 can further connect and fix the side panels 204 and the moving seat 207, thereby improving the connection stability between the side panels 204 and the reinforcing rib plate 205. The internal threads of the two sets of moving seats 207 are connected with a bidirectional screw rod 206, and the bidirectional screw rod 206 is rotatably connected with the conveying frame 101. When the bidirectional screw rod 206 rotates, it can drive the moving seats 207 on both sides and the side panels 204 on both sides to move relative to or away from each other, thereby realizing the adjustment of the distance between the two sets of side panels 204 to meet the requirements of limiting cardboards of different widths.

[0030] The pushing mechanism 3 includes an L-shaped moving seat 301 fixedly connected to one side of the conveying frame 101, a sliding block 302 is slidably connected inside the L-shaped moving seat 301, a cylinder 303 is fixedly penetrated inside the sliding block 302, and the setting of the sliding block 302 can provide support for the cylinder 303. A connecting rod 305 is fixedly connected to the output end of the cylinder 303, and a plurality of pushing bars 306 are evenly fixedly connected to the side of the connecting rod 305 away from the cylinder 303. When the cylinder 303 starts working, it pushes the connecting rod 305 and the pushing bar 306 to move, so that the pushing bar 306 can push the cardboard to move to one side of the belt conveyor 102. The top of the sliding block 302 is rotatably connected with a second adjusting screw 304, which is threadedly connected to the L-shaped moving seat 301. The second adjusting screw 304 is used to drive the sliding block 302 and the cylinder 303 to move up and down when rotating, so as to adjust the height of each group of pushing strips 306 to meet the needs of pushing cardboards of different thicknesses. The top of the carrier plate 201 is evenly provided with a plurality of avoidance grooves 307, each group of avoidance grooves 307 is respectively adapted to each group of pushing strips 306, and the setting of the avoidance grooves 307 can accommodate the pushing strips 306, so as to provide corresponding activity space for the up and down movement of the pushing strips 306.
