Description

Technical Field

[0001] The invention belongs to the field of corrugated cardboard manufacturing, and in particular relates to a waste removal device for a corrugated cardboard production line. Background Art

[0002] Corrugated cardboard, also known as corrugated paperboard, is made by bonding at least one layer of corrugated paper and one layer of containerboard. It exhibits good elasticity and ductility and is primarily used to make cartons, cardboard inserts, and other packaging materials for fragile goods. It is made by beating straw pulp and waste paper to create a base similar to yellow cardboard. This is then machined and rolled into a corrugated shape. The surface is then bonded to the containerboard using adhesives such as sodium silicate.

[0003] The corrugated cardboard manufacturing process requires cutting to meet production requirements. However, this can lead to issues with the quality of the corrugated cardboard, such as paper scraps or lint on the edges, or issues with size and specifications that compromise the quality of the cardboard. Existing waste removal devices suffer from poor structural layouts, making it impossible to accurately and effectively remove waste from the cardboard without shutting down the machine, impacting reliability and efficiency. Therefore, there is an urgent need to develop a waste removal device for corrugated cardboard production lines that can overcome these shortcomings. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a waste removal device for a corrugated cardboard production line, aiming to solve the problem that the existing waste removal devices cannot achieve accurate and effective waste removal of corrugated cardboard without stopping the machine.

[0005] An embodiment of the present invention is implemented as follows: a waste removal device for a corrugated cardboard production line includes a base, a detection mechanism for detecting unqualified corrugated cardboard mounted on the base, a waste removal mechanism for removing unqualified corrugated cardboard mounted on the base, and a corrugated cardboard conveying mechanism including side panels, pillars, conveying rollers, and a drive assembly. Two side panels are fixed to the upper side of the base via the pillars, and a plurality of conveying rollers are mounted between the two side panels. The drive assembly is mounted on the side panels and is configured to drive the plurality of conveying rollers to rotate in the same direction, thereby conveying the corrugated cardboard placed thereon via the plurality of conveying rollers. The detection mechanism is configured to detect the corrugated cardboard on the conveying rollers, and the waste removal mechanism is configured to remove unqualified corrugated cardboard detected by the detection mechanism from the conveying rollers. A removal and conveying release mechanism is mounted on the corrugated cardboard conveying mechanism. When the waste removal mechanism is in operation and the drive assembly is in a normal operating state, the removal and conveying release mechanism is configured to release the driving force of the drive assembly on the conveying roller corresponding to the waste removal mechanism.

[0006] A further technical solution is that a roller shaft is installed through the conveying roller, and the two ends of the roller shaft are rotatably connected to the side plates; the driving assembly includes a conveying motor, a transmission belt and a pulley, and a transmission cavity is opened in one of the side plates, and a pulley is installed and fixed on the roller shaft in the transmission cavity, and the two adjacent pulleys are connected by a transmission belt; the conveying motor is installed and fixed on the side plate, and the output end of the conveying motor is transmission-connected to one of the roller shafts.

[0007] A further technical solution is that the detection mechanism includes a mounting frame, a shooting component, a processor and a support rod. The mounting frame is installed and fixed on the base, a support rod is installed and fixed in the middle of the top of the mounting frame, a processor is installed and fixed on the lower side of the end of the support rod away from the mounting frame, and the shooting component is electrically connected to the processor; the shooting component is used to take pictures of the corrugated cardboard on the conveyor roller, and the shooting component transmits the picture to the processor, and the processor is used to determine whether the picture is qualified.

[0008] A further technical solution is that the waste removal mechanism includes a waste removal telescopic cylinder, a cylinder support and a waste pushing plate. The waste pushing plate is a side-mounted "sun" shaped structure, and the conveying roller passes through the two holes of the waste pushing plate. The waste removal telescopic cylinder is installed and fixed on the base through the cylinder support, and the end of the telescopic core shaft of the waste removal telescopic cylinder is connected and fixed to the bottom of the waste pushing plate.

[0009] A further technical solution is that the waste removal telescopic cylinder is also electrically connected to the processor; when the processor determines that the picture taken by the shooting component is qualified, the waste removal telescopic cylinder does not work; when the picture is unqualified, the waste removal telescopic cylinder pushes the waste pushing plate to move and remove the unqualified corrugated cardboard.

[0010] A further technical solution is that the removal and conveying release mechanism includes an air pipe, a vacuum pump, an air distribution pipe, a connecting edge plate and a pneumatic elastic telescopic cylinder. The conveying roller passing through the hole of the waste pushing plate is rotatably connected to its roller shaft, and the conveying roller on the outside of the waste pushing plate is fixedly connected to its roller shaft; an air distribution pipe is installed and fixed on the side plate, one end of the roller shaft passing through the hole of the waste pushing plate is sealed and rotatably connected to the air distribution pipe, and one end of the roller shaft passing through the hole of the waste pushing plate is communicated with the air distribution cavity of the air distribution pipe, the vacuum pump is installed and fixed on the base, and the vacuum pump is fixed on the base.

[0011] According to a further technical solution, the cavity is an arc-shaped structure with a middle portion away from the roller axis.

[0012] A further technical solution is that when there is no external force, the connecting edge plate elastically abuts against the connecting groove under the elastic force of the pneumatic elastic telescopic cylinder; when the vacuum pump is working, the trachea, air distribution cavity, main air cavity and branch air cavity generate negative pressure, and the pneumatic elastic telescopic cylinder drives the connecting edge plate and the connecting groove to separate.

[0013] According to a further technical solution, the processor is also electrically connected to the vacuum pump; when the processor determines that the picture taken by the shooting component is qualified, the vacuum pump does not work; when the picture is unqualified, the vacuum pump works.

[0014] An embodiment of the present invention provides a waste removal device for a corrugated cardboard production line. Through the special limitation of the corrugated cardboard conveying mechanism, a driving assembly can drive several conveying rollers to rotate in the same direction, thereby conveying the corrugated cardboard placed thereon through the several conveying rollers. In conjunction with the conventional arrangement of the detection mechanism and the waste removal mechanism, the detection of corrugated cardboard and the removal of unqualified corrugated cardboard can be achieved.

[0015] In addition, by further limiting the removal of the conveying release mechanism, when the waste removal mechanism is working, under the condition that the driving component is working normally, removing the conveying release mechanism can release the driving force of the driving component on the conveying roller corresponding to the waste removal mechanism, that is, stop the driving force of the corresponding conveying roller during waste removal, which can be achieved without controlling the driving component to stop working. The waste removal mechanism can be used to accurately and effectively remove corrugated cardboard, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figure 1-2 As shown, a waste removal device for a corrugated cardboard production line provided by one embodiment of the present invention includes a base 3, on which a detection mechanism for detecting unqualified corrugated cardboard is installed, and a waste removal mechanism for removing unqualified corrugated cardboard is also installed on the base 3, and further includes:

[0025] A corrugated cardboard conveying mechanism includes side panels 1, pillars 2, conveying rollers 12, and a drive assembly. Two side panels 1 are fixed to the upper side of the base 3 via the pillars 2. A plurality of conveying rollers 12 are installed between the two side panels 1. The drive assembly is installed on the side panels 1 and is used to drive the plurality of conveying rollers 12 to rotate in the same direction, thereby conveying the corrugated cardboard placed thereon via the plurality of conveying rollers 12.

[0026] The detection mechanism is used to detect the corrugated cardboard on the conveying roller 12, and the waste removal mechanism is used to remove the unqualified corrugated cardboard detected by the detection mechanism from the conveying roller 12;

[0027] The removal conveying release mechanism is installed on the corrugated cardboard conveying mechanism. When the waste removal mechanism is working, under the condition that the driving component is working normally, the removal conveying release mechanism is used to release the driving force of the driving component on the conveying roller 12 corresponding to the waste removal mechanism.

[0028] In the embodiment of the present invention, through the special limitation of the corrugated cardboard conveying mechanism, the driving assembly can drive several conveying rollers 12 to rotate in the same direction, so that the corrugated cardboard placed thereon is conveyed by the several conveying rollers 12, and combined with the conventional arrangement of the detection mechanism and the waste removal mechanism, the detection of corrugated cardboard and the removal of unqualified ones can be realized.

[0029] In addition, by further limiting the removal of the conveying release mechanism, when the waste removal mechanism is working, under the condition that the driving component is working normally, removing the conveying release mechanism can release the driving force of the driving component on the conveying roller 12 corresponding to the waste removal mechanism, that is, the driving force of the corresponding conveying roller 12 is stopped during waste removal, which can be achieved without controlling the driving component to stop working. The waste removal mechanism can be used to accurately and effectively remove corrugated cardboard, thereby improving work efficiency.

[0030] like Figure 1-3 As shown, as a preferred embodiment of the present invention, the two side panels 1 are arranged in parallel, and a pillar 2 is installed and fixed at each end of the side panel 1, and the pillar 2 is fixed on the base 3, that is, one side panel 1 is supported by the two pillars 2; a roller shaft 18 is installed through the conveying roller 12, and the two ends of the roller shaft 18 are correspondingly connected to the side panel 1 for rotation; the driving assembly includes a conveying motor 11, a transmission belt 21 and a pulley 22, one of the side panels 1 is provided with a transmission cavity 20, and a pulley 22 is installed and fixed on the roller shaft 18 in the transmission cavity 20, and two adjacent pulleys 22 are connected by a transmission belt 21, so that by driving one roller shaft 18 to rotate, all roller shafts 18 can rotate in the same direction under the drive of the transmission belt 21 and the pulley 22; the conveying motor 11 is installed and fixed on the side panel 1, and the output end of the conveying motor 11 is connected to one of the roller shafts 18 for transmission, and the driving of all conveying rollers 12 is achieved by the conveying motor 11.

[0031] The detection mechanism includes a mounting frame 9, a shooting component 14, a processor 15 and a support rod 16. The mounting frame 9 is installed and fixed on the base 3. The mounting frame 9 preferably adopts an inverted U-shaped frame. A support rod 16 is installed and fixed in the middle of the top of the mounting frame 9. A processor 15 is installed and fixed on the lower side of the end of the support rod 16 away from the mounting frame 9. The shooting component 14 is electrically connected to the processor 15. The shooting component 14 and the processor 15 can be specifically made of existing conventional technology; the shooting component 14 takes a picture of the corrugated cardboard on the conveying roller 12, and the shooting component 14 transmits the picture to the processor 15, and the processor 15 determines whether the picture is qualified; if it is qualified, the waste removal mechanism does not work; if it is unqualified, the waste removal mechanism removes the unqualified corrugated cardboard; the combined application of the shooting component 14 and the processor 15 has a simple and reasonable structure, and can accurately determine whether the corrugated cardboard is qualified, which will not be described in detail.

[0032] The waste removal mechanism includes a waste removal telescopic cylinder 6, a cylinder support 7, and a waste pushing plate 17. The waste pushing plate 17 is a side-mounted "day" - shaped structure. The waste pushing plate 17 is perpendicular to the conveyor roller 12, and the conveyor roller 12 passes through two holes of the waste pushing plate 17. Note that the conveyor roller 12 cannot contact the waste pushing plate 17 to avoid the waste pushing plate 17 affecting the rotation of the conveyor roller 12. The waste removal telescopic cylinder 6 is fixedly installed on the base 3 through the cylinder support 7. The waste removal telescopic cylinder 6 is arranged parallel to the conveyor roller 12. The end of the telescopic core shaft of the waste removal telescopic cylinder 6 is fixedly connected to the bottom of the waste pushing plate 17. The waste removal telescopic cylinder 6 is used to support the waste pushing plate 17 and push the waste pushing plate 17 to move. The waste pushing plate 17 can push the unqualified corrugated cardboard on the conveyor roller 12 down. The waste removal telescopic cylinder 6 is also electrically connected to the processor 15. The processor 15 controls the waste removal telescopic cylinder 6 to work according to the determination result. That is, when the picture is qualified, the waste removal telescopic cylinder 6 does not work; when the picture is unqualified, the waste removal telescopic cylinder 6 pushes the waste pushing plate 17 to move, and pushes the unqualified corrugated cardboard into the waste receiving box 13.

[0033] Further, a waste receiving box 13 for receiving the unqualified corrugated cardboard is also provided on one side of the base 3 away from the waste removal telescopic cylinder 6. There is no specific limitation on the waste receiving box 13, as long as it can receive the corrugated cardboard dropped from the conveyor roller 12.

[0034] Such as Figure 1-5As shown, as a preferred embodiment of the present invention, the removal and conveying release mechanism includes an air pipe 4, a vacuum pump 5, an air distribution pipe 10, a connecting edge plate 25 and a pneumatic elastic telescopic cylinder 26. The conveying roller 12 passing through the hole of the waste pushing plate 17 is rotatably connected to its roller shaft 18, and the conveying roller 12 on the outside of the waste pushing plate 17 is fixedly connected to its roller shaft 18; an air distribution pipe 10 is installed and fixed on the side plate 1, and one end of the roller shaft 18 passing through the hole of the waste pushing plate 17 is sealed and rotatably connected to the air distribution pipe 10, and one end of the roller shaft 18 passing through the hole of the waste pushing plate 17 is communicated with the air distribution cavity 19 of the air distribution pipe 10, the vacuum pump 5 is installed and fixed on the base 3, and the vacuum pump 5 is communicated with the air distribution cavity 19 of the air distribution pipe 10 through the air pipe 4; A cavity 23 is provided in the conveying roller 12 passing through the hole of the plate 17. The cavity 23 is an arc-shaped structure with the middle part away from the roller shaft 18. A plurality of connecting grooves 24 are circumferentially distributed on the side wall of the cavity 23. A plurality of pneumatic elastic telescopic cylinders 26 are circumferentially installed and fixed on the roller shaft 18 corresponding to the middle part of the cavity 23. The pneumatic elastic telescopic cylinder 26 can be pneumatically telescopically controlled. When there is no pneumatic control, it is sufficient to have elastic force. No limitation or elaboration is made. A connecting edge plate 25 that can be abutted against the connecting groove 24 is fixed on the end of the pneumatic elastic telescopic cylinder 26 away from the roller shaft 18. A main air cavity 28 that is connected to the air distribution cavity 19 of the air distribution pipe 10 is provided on the inner side of the roller shaft 18. The pneumatic elastic telescopic cylinder 26 is also connected to the main air cavity 28 through a branch air cavity 27 provided in the roller shaft 18.

[0035] When there is no external force, the connecting rib 25 is elastically abutted against the connecting groove 24 under the elastic force of the pneumatic elastic telescopic cylinder 26. At this time, the conveying roller 12, the connecting rib 25, the pneumatic elastic telescopic cylinder 26 and the roller shaft 18 form a whole, that is, they can only rotate together; when the vacuum pump 5 is working, the air pipe 4, the air distribution cavity 19, the main air cavity 28 and the branch air cavity 27 generate negative pressure, and the pneumatic elastic telescopic cylinder 26 drives the connecting rib 25 and the connecting groove 24 to separate. At this time, the roller shaft 18, the connecting rib 25 and the pneumatic elastic telescopic cylinder 26 are separated from the conveying roller 12 and rotate independently, that is, the conveying roller 12 loses driving force.

[0036] Furthermore, the processor 15 is also electrically connected to the vacuum pump 5. The processor 15 controls the vacuum pump 5 to work according to the judgment result, that is, when the picture is qualified, the vacuum pump 5 does not work; when the picture is unqualified, the vacuum pump 5 works, and the air pipe 4, the air distribution cavity 19, the main air cavity 28 and the branch air cavity 27 generate negative pressure. The pneumatic elastic telescopic cylinder 26 drives the connecting edge plate 25 and the connecting groove 24 to separate. At this time, the roller shaft 18, the connecting edge plate 25 and the pneumatic elastic telescopic cylinder 26 are separated from the conveying roller 12 and rotate independently, so that the conveying roller 12 loses the driving force, which is conducive to the waste removal telescopic cylinder 6 to drive the waste pushing plate 17 to push the unqualified corrugated cardboard into the waste receiving box 13, that is, to avoid the continuous rotation of the conveying roller 12 so that the waste pushing plate 17 pushes the unqualified corrugated cardboard in the X+Y direction, thereby improving the reliability and efficiency of waste removal.

[0037] Furthermore, the connecting ridge 25 can adopt an arc-shaped structure. As for the curvature relationship between the connecting ridge 25 and the connecting groove 24, there is no limitation. The length of the connecting ridge 25 and the connecting groove 24 can be arranged as needed. It is sufficient to realize the linkage between the connecting ridge 25 and the conveying roller 12, and no further details are given.

[0038] The above-mentioned embodiment of the present invention provides a waste removal device for a corrugated cardboard production line. While ensuring the normal transportation, inspection and waste removal of the corrugated cardboard, by arranging and removing the conveying release mechanism, the corresponding conveying roller 12 can be controlled to lose the driving force without stopping the machine, thereby avoiding the X+Y direction deviation of the waste pushing plate 17 during the process of pushing unqualified corrugated cardboard. The structural arrangement is simple and reasonable, and the reliability and efficiency of waste removal are improved.

[0039] Furthermore, the mounting frame 9 is also mounted with a control module 8 for controlling the conveyor motor 11. The specific configuration is not limited to this. The control module 8 controls the conveyor roller 12 to operate at a certain speed. The control, model, and circuit connections of the various components in the device are not specifically limited and can be flexibly configured in actual applications.

[0040] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
