Technical fields:

[0001] This utility model relates to the field of cardboard processing technology, and more specifically to a cardboard processing folding guide conveyor mechanism. Background technology:

[0002] Existing cardboard processing equipment can bend cardboard during transport and nail it to the corresponding positions.

[0003] During the bending and conveying process, bending guide plates are generally installed on the conveyor frames on both sides, so that the cardboard is bent along the bending guide plates during the conveying process. However, the bending guide plates are rigid parts, and the surface of the cardboard is severely worn when it is conveyed and bent along them, which affects its surface quality. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cardboard processing folding guide conveyor mechanism. It can fold the two sides of the cardboard inward through the outer guide bending conveyor belt. Since the outer guide bending conveyor belt runs synchronously with the lower conveyor belt and has a flexible structure, it causes less wear on the cardboard and can ensure the surface quality of the cardboard while bending the two sides.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A cardboard processing folding guide conveying mechanism includes a frame, two conveying beams extending forward and backward are installed in the middle of the frame, and multiple connecting frames are fixed on the left and right sides of the rear of the frame. A corresponding upper conveying beam is fixed on all connecting frames on the same side, and the upper conveying beam is located above the rear of the corresponding conveying beam.

[0007] An upper conveyor belt is installed on the upper conveyor beam, and a lower conveyor belt is installed on the inner side of the conveyor beam. A conveying channel is formed between the lower part of the upper conveyor belt and the upper part of the corresponding lower conveyor belt.

[0008] An external guide bending conveyor belt is installed on the outer side of the conveying beam;

[0009] The conveying beam includes a bottom beam, a connecting beam extending left and right from the bottom of the frame, fixed in the middle. An inner vertical plate is fixed to the inner wall of the bottom beam. The upper part of the inner vertical plate extends beyond the top surface of the bottom beam. The rear and front ends of the upper part of the inner vertical plate are movably connected to a rotating shaft via bearings. A drive wheel and a synchronous pulley are fixed to the outer and inner ends of the rear rotating shaft, respectively. A front guide wheel is movably connected to a connecting shaft fixed to a support frame in the middle of the conveying beam via bearings. A [missing information - likely a component or material] is fixed to the outer wall of the top of the inner vertical plate at the front of the upper conveying beam. A horizontal tensioning plate has a horizontal extension mounting plate fixed on the outer side of the top of the inner vertical plate in front of the horizontal tensioning plate. The top surface of the horizontal tensioning plate is movably connected to three tensioning guide rollers arranged in a triangular pattern via a hinge shaft. Multiple conical guide rollers arranged in front and behind are movably connected to the top surface of the horizontal extension mounting plate via a hinge shaft. The outer guide bending conveyor belt is tensioned between the drive wheel and the front guide wheel. The middle part of the upper belt of the outer guide bending conveyor belt is folded over and coiled along the three tensioning guide rollers and driven against the side wall surface of the inner side of the corresponding conical guide roller.

[0010] A radial annular limiting edge is formed on the outer wall of the bottom end of the tapered guide roller, and the bottom surface of the middle fold of the upper part of the outer guide bending conveyor belt is close to or closely attached to the top surface of the radial annular limiting edge.

[0011] A front extension horizontal plate is fixed on the front wall of the upper conveying beam corresponding to the conical guide roller. An upper guide plate is fixed on the top surface of the front extension horizontal plate. The outer side of the upper guide plate is an inclined surface that extends outward and downward. Multiple butterfly guide wheels corresponding to the conical guide roller are movably connected to the inclined surface through a hinge shaft.

[0012] The outer side of the inner vertical plate between the rear of the horizontal tensioning plate and the drive wheel is movably connected to multiple intermediate guide wheels via a hinge shaft. The top surface of the intermediate guide wheels is in contact with the bottom surface of the upper belt of the outer guide bending conveyor belt.

[0013] A long horizontal plate is fixed to the top outer wall of the inner vertical plate between the front guide wheel and the foremost conical guide roller. A horizontal guide roller is movably connected to the top surface of the long horizontal plate through a hinge shaft. The side wall of the corresponding part of the upper belt of the outer guide bending conveyor belt runs in close contact with the side wall of the corresponding horizontal guide roller.

[0014] Multiple intermediate support frames are fixed on the top surface of the outer side of the bottom beam between the front of the foremost conical guide roller and the front guide wheel.

The front end of the upper belt of the outer guide bending conveyor belt is tensioned on the front guide wheel, and its lower belt extends backward along the top surface of the front guide wheel and all the middle guide wheels and runs backward along the bottom surface of the lower guide wheel to the drive wheel.

[0015] The outstanding effect of this utility model is:

[0016] It can bend the two sides of the cardboard inward through the outer guide bending conveyor belt. Since the outer guide bending conveyor belt runs synchronously with the lower conveyor belt and has a flexible structure, it causes less wear on the cardboard, ensuring the surface quality of the cardboard while bending the two sides.

[0017] The radial annular limiting edge formed on the outer wall of the bottom end of its tapered guide roller can support the bottom surface of the middle fold of the upper belt of the outwardly guiding and bending conveyor belt, preventing it from slipping and ensuring its normal operation.

Two conveying beams 20 extending forward and backward are installed in the middle of the frame 10. Multiple connecting frames 1 are fixed on the left and right sides of the rear of the frame 10. A corresponding upper conveying beam 30 is fixed on all connecting frames 1 on the same side. The upper conveying beam 30 is located above the rear of the corresponding conveying beam 20.

[0025] An upper conveyor belt 31 is installed on the upper conveyor beam 30, and a lower conveyor belt 21 is installed on the inner side of the conveyor beam 20.

The outer walls of the two tensioning guide rollers 241 movably connected to the front and rear parts of the inner side of the horizontal tensioning plate 24 via a hinge shaft are conical, and the outer wall of the outer tensioning guide roller 241 is cylindrical. This structure ensures the tension of the outer guide bending conveyor belt 40 when it is tensioned by the three tensioning guide rollers 241, and prevents it from slipping off.

[0030] This radial annular limiting edge 252 can ensure that the bottom surface of the middle fold of the upper belt body of the outer guide bending conveyor belt 40 can be supported, preventing it from sliding down and ensuring its normal operation.

[0031] Furthermore, a front extension horizontal plate 32 is fixed on the front wall of the upper conveying beam 30 corresponding to the conical guide roller 251, and an upper guide plate 33 is fixed on the top surface of the front extension horizontal plate 32. The outer side of the upper guide plate 33 is an inclined surface extending outward and downward, and multiple butterfly guide wheels 34 corresponding to the conical guide roller 251 are movably connected to the inclined surface through a hinge shaft.

[0033] Furthermore, an elongated horizontal plate 50 is fixed to the top outer wall of the inner vertical plate between the front guide wheel 240 and the foremost conical guide roller 251. A horizontal guide roller 51 is movably connected to the top surface of the elongated horizontal plate 50 via a hinge shaft. The side wall of the corresponding part of the upper belt of the outer guide bending conveyor belt 40 runs in close contact with the side wall of the corresponding horizontal guide roller 51.

[0034] Furthermore, multiple intermediate support frames are fixed on the top surface of the outer side of the bottom beam between the front of the foremost conical guide roller 251 and the front guide wheel 240. A middle guide wheel 3 is movably connected to the connecting shaft fixed on each intermediate support frame via a bearing. The front guide wheel 240 and all the middle guide wheels 3 gradually rise from front to back. The outer side of the inner vertical plate below the foremost conical guide roller 251 is movably connected to the lower guide wheel 4 via a hinge shaft. The front end of the upper belt of the outer guide bending conveyor belt 40 is tensioned on the front guide wheel 240, and its lower belt extends backward along the top surface of the front guide wheel 240 and all the middle guide wheels 3 and runs backward along the bottom surface of the lower guide wheel 4 to the transmission wheel 22.

[0035] Furthermore, the rear end of the rotating shaft at the front end of the upper part of the inner vertical plate is fixed with a front conveyor synchronous pulley 5, and the lower conveyor belt 21 is a synchronous belt, which is tensioned on the front conveyor synchronous pulley 5 and the synchronous pulley 23.

The bottom surface of the guide wheel 37 presses against the top surface of the lower belt body of the upper conveyor belt 31.

[0037] In this embodiment, the lower conveyor belt 21 runs, and the cardboard is conveyed forward on the upper belt of the two lower conveyor belts 21. The bottom surface of the lower belt of the corresponding upper conveyor belt 31 is close to the top surface of the cardboard, which limits its movement. The left and right sides of the cardboard extend outward from the conveying channel and rest against the rear top surface of the upper belt of the two outer guide bending conveyor belts 40. The middle of the top surface of the connecting beam of the frame 10 is fixed with a front-to-back extended intermediate support frame, on which multiple front-to-back arranged guide wheels are movably connected to support the bottom surface of the conveyed cardboard.

[0038] During its forward conveying process, the left and right side plates of the cardboard are bent inward along the upper belt of the two outer guide bending conveyor belts 40. When bending, they move inward along the corresponding butterfly guide rollers 34, thereby achieving guided bending. After passing the butterfly guide rollers 34, the bent side plates will be conveyed forward along the bottom surface of the corresponding upper belt of the outer guide bending conveyor belt 40 and the top surface of the upper belt of the lower conveyor belt 21, achieving forward conveying after bending, with good bending and conveying effect.
