Description

TECHNICAL FIELD

[0001] The present application relates to the field of corrugated carton production, in particular to a corrugated carton production process and a scrap separating device applied to the process. BACKGROUND

[0002] The corrugated board is made into a corrugated carton through die cutting, indentation, nailing or gluing. The corrugated carton is the most widely used packaging product, and its demand has been the first among various packaging products for more than half a century. The corrugated carton gradually replaces wooden boxes and other transportation packaging containers due to its superior use performance and good processing performance, and becomes the main force of transportation packaging. In addition to protecting goods, facilitating storage and transportation, it also beautifies and promotes goods. The corrugated carton is a green and environmentally friendly product, which is beneficial to environmental protection and loading and unloading transportation.

[0003] During the processing and forming of the corrugated carton, the corrugated paper needs to be cut, and cutting the corrugated board will generate scraps. These scraps will be transported to the storage device by the conveying device and dispersed in the air or enter the packaged corrugated carton under the action of air flow.

[0004] According to the related technology in the above, the inventor believes that the scattered scraps in the air or in the processed corrugated carton will pollute the environment. SUMMARY

[0005] In order to improve the defect that the scraps attached to the corrugated board pollute the environment, the present application provides a scrap separating device.

[0006] On the one hand, the present application provides a corrugated carton production process, which adopts the following technical scheme:

[0007] A corrugated carton production process, comprising the following steps:

[0008] S1: material preparation: preparing corrugated board and cutting the corrugated board into a shape required for laminated corrugated carton;

[0009] S2: indentation and slotting: the indentation machine performs indentation on the corrugated board, and slotting is performed at the indentation after indentation;

[0010] S3: scrap removal: the corrugated board after slotting is placed on the scrap separating device to separate the scraps generated on the surface of the corrugated board due to cutting and slotting;

[0011] S4: printing: printing is performed on the surface of the corrugated board;

[0012] S5: joining: the corrugated paper edges are connected by nailing, gluing or tape jointing.

[0013] By adopting the above technical solution, the corrugated cardboard needs to be cut first and then creased and grooved during the process of making corrugated boxes. Debris will be generated during the cutting and groove processes. The debris remaining on the surface of the corrugated cardboard will pollute the environment and the corrugated boxes. The debris on the surface of the corrugated cardboard is removed through the debris removal step, which can improve the defect of debris attached to the corrugated cardboard polluting the environment.

[0014] This application also provides a debris separation device for use in the above-mentioned corrugated box production process, which adopts the following technical solution:

[0015] A chip separation device includes a conveying device, the conveying device including a mounting frame, two rotating shafts rotatably connected to the mounting frame, a plurality of driving wheels fixedly connected to the rotating shafts, and a conveying belt sleeved between the two rotating shafts, the conveying belt sleeved on the driving wheels, a fixed beam fixedly connected to the mounting frame, a vibrating assembly provided on the fixed beam, and a chip collecting groove provided at the bottom of the mounting frame;

[0016] The vibration assembly includes a push rod slidably connected to a fixed beam, a resistance block fixedly connected to the push rod, a driving rod hinged to the fixed beam, a vibration rod fixedly connected to the driving rod, a protrusion fixedly connected to the vibration rod, and a reset spring connected between the driving rod and the fixed beam. The angle between the driving rod and the vibration rod is an obtuse angle. The protrusion slidably contacts the resistance block. A driving assembly for driving the push rod to move back and forth is provided on the fixed beam.

[0017] By adopting the above technical solution, the corrugated cardboard to be processed into corrugated boxes after cutting is placed on the conveyor belt, and the driving shaft is rotated to drive the driving wheel and the belt on the driving wheel to rotate, thereby driving the corrugated cardboard to move. When the corrugated cardboard moves, the driving component drives the vibration component to work, and the movement of the push rod drives the resistance block to move. When the resistance block collides with the protrusion, the protrusion pushes the driving rod to rotate around the hinge point, thereby driving the vibration rod to hit the bottom of the corrugated cardboard, so that the debris under the corrugated cardboard is vibrated and falls off, and falls into the chip collecting trough for collection, thereby reducing the possibility of the debris on the corrugated cardboard entering the next workplace or the corrugated box packaging site with the corrugated cardboard, and improving the defect of debris attached to the corrugated cardboard polluting the environment.

[0018] Optionally, the driving assembly includes a driving motor fixedly connected to the fixed beam, a driving gear connected to the output end of the driving motor and a driven gear rotatably connected to the fixed beam, and a rack is fixedly connected to the push rod, and the rack is engaged with the driven gear.

[0019] By adopting the above technical solution, the driving motor drives the driving gear to rotate, the driven gear engages and rotates with the driving gear, and engages with the rack, driving the push rod to move along the length direction of the mounting frame to realize the operation of the vibration component.

[0020] Optionally, a cleaning assembly for cleaning debris is provided on the mounting frame, and the cleaning assembly includes a bracket fixedly connected to the mounting frame, a first motor fixedly connected to the bracket, a rotating rod connected to the output end of the first motor, a rotating drum rotatably connected to the rotating rod, and adhesive paper glued to the rotating drum, the rotating rod is arranged perpendicular to the bracket, the rotating drum is arranged perpendicular to the rotating rod, and the adhesive paper is arranged in multiple layers on the rotating drum.

[0021] By adopting the above technical solution, the first motor drives the rotating rod and the rotating drum and adhesive paper on the rotating rod to rotate above the corrugated cardboard. The adhesive paper contacts the surface of the corrugated cardboard and adheres to the debris on the surface of the corrugated cardboard. The rotation of the rotating shaft can improve the smoothness of the corrugated cardboard transportation and at the same time improve the cleaning effect of the adhesive paper on the debris on the surface of the corrugated cardboard.

[0022] Optionally, a second motor is fixedly connected to the rotating rod, and an output end of the second motor is coaxially connected to the end of the rotating drum.

[0023] By adopting the above technical solution, the second motor drives the rotating rod to rotate, thereby improving the cleaning effect of the adhesive paper.

[0024] Optionally, the mounting frame is provided with a cleaning component for tearing off the adhesive paper, the cleaning component includes a fixing frame fixedly connected to the mounting frame, a first cylinder fixedly connected to the fixing frame, a fixing plate connected to the output end of the cylinder, a cleaning plate connected to the fixing plate, a second cylinder fixedly connected to the fixing plate and a clamping plate connected to the output end of the second cylinder, the first cylinder is perpendicular to the conveyor belt, the second cylinder is arranged perpendicular to the first cylinder, and the clamping plate is abutted against the cleaning plate under the action of the second cylinder.

[0025] By adopting the above technical solution, when the surface of the adhesive paper is full of debris, the stickiness of the adhesive paper decreases, and the first motor drives the rotating drum to leave the corrugated cardboard. Then the first cylinder drives the fixing plate, the cleaning plate, the clamping plate and the second cylinder to move toward the rotating drum until the cleaning plate is inserted between the end of the adhesive paper and the rotating drum. At this time, the second cylinder works to push the clamping plate toward the cleaning plate, abuts against the cleaning plate and clamps the adhesive paper. Then the second motor drives the rotating drum to rotate. As the rotating drum rotates, the adhesive paper at the outermost end of the rotating drum clamped by the cleaning plate and the clamping plate is torn off, revealing clean adhesive paper.

[0026] Optionally, a chamfer is provided at one end of the cleaning plate away from the fixing plate, and the chamfer is located on a side of the cleaning plate close to the clamping plate.

[0027] By adopting the above technical solution, the chamfer can facilitate the insertion of the cleaning plate between the two layers of adhesive paper, thereby facilitating the peeling of the outermost layer of adhesive paper.

[0028] Optionally, a release paper is glued to the end of the adhesive paper, and the release paper is located on a side of the adhesive paper close to the rotating drum.

[0029] By adopting the above technical solution, the anti-sticking paper can separate the end of the outer adhesive paper from the inner adhesive paper, making it convenient for the removal plate to peel off the used outermost adhesive paper.

[0030] Optionally, the release paper is arranged in a V-shape, and the V-shaped opening of the release paper is arranged toward the end of the adhesive paper.

[0031] By adopting the above technical solution, the V-shaped release paper can further reduce the possibility of adhesion between the outer adhesive paper and the inner adhesive paper, making the outer adhesive paper easier to peel off.

[0032] In summary, this application has the following beneficial technical effects:

[0033] 1. Through the arrangement of the conveyor belt and the vibration component located on the fixed beam, the vibration component can vibrate the corrugated cardboard on the conveyor belt during the movement of the corrugated cardboard, and shake off the debris attached to the surface of the corrugated cardboard, thereby improving the defect that the debris moves with the corrugated cardboard and pollutes the environment.

[0034] 2. Through the arrangement of the rotating drum on the rotating rod and the adhesive paper glued to the rotating drum, the debris on the surface of the corrugated cardboard can be rolled and adhered, thereby improving the cleaning degree of the debris on the surface of the corrugated cardboard.

[0056] Reference Figure 4 The push rod 21 is arranged perpendicular to the fixed beam 18, and a dovetail block is fixedly connected to the push rod 21. A dovetail groove is opened on the fixed beam 18 along a length direction perpendicular to the fixed beam 18, and the dovetail block and the dovetail groove are slidably matched.

[0057] Reference Figure 4 A connecting block 182 is fixedly connected to the upper side wall of the fixed beam 18, one end of the return spring 24 is fixedly connected to the push rod 21, and the other end is fixedly connected to the driving rod 25, the protrusion 23 is located on the side of the push rod 21 away from the fixed beam 18, and the protrusion 23 is located on the side of the vibration rod 22 close to the fixed beam 18, and the end of the vibration rod 22 is fixedly connected to the vibration block 221, the driving rod 25 and the vibration rod 22 are integrally formed, and the end of the driving rod 25 connected to the vibration rod 22 is hinged to the connecting block 182, and the angle between the driving rod 25 and the vibration rod 22 is an obtuse angle.

[0059] ReferenceFigure 5 The driven gear 33, rack 211, and vibration assembly are arranged in two symmetrical groups about the center of the drive gear 32. When the drive motor 31 is operating, it drives the drive gear 32 to rotate. The two driven gears 33 meshing with the drive gear 32 rotate in the same direction, and by meshing with the rack 211, they drive the two push rods 21 to move in opposite directions or away from each other. When the push rods 21 move, the abutment block 26 abuts the protrusion 23, driving the drive rod 25 to hinge around the fixed beam 18, thereby causing the vibration rod 22 to swing around the hinge point, causing the vibration block 221 to strike the corrugated cardboard.

[0060] Reference Figure 5 A chip collecting groove 19 is provided at the bottom of the mounting frame 11 . When the vibration block 221 hits the corrugated cardboard, the debris on the corrugated cardboard falls into the chip collecting groove 19 .

The cleaning assembly 4 includes a bracket 41 fixedly connected to the mounting frame 11, a first motor 42 fixedly connected to the bracket 41, a rotating rod 43 connected to the output end of the first motor 42, a rotating drum 44 rotatably connected to the rotating rod 43, and an adhesive paper 45 glued to the rotating drum 44.

[0062] Reference Figure 6 Three rotating rods 43 are evenly arranged along the circumferential direction of the output shaft of the first motor 42. A second motor 431 is fixed on the rotating rod 43. The output end of the second motor 431 is coaxially connected to the rotating drum 44. The rotating rod 43 is perpendicular to the bracket 41, and the rotating drum 44 is perpendicular to the rotating rod 43. Multiple layers of adhesive paper 45 are glued to the outside of the rotating drum 44.

[0063] Reference Figure 7 The end of the adhesive paper 45 is glued with a release paper 451, which is located on the side of the adhesive paper 45 close to the rotating drum 44. The release paper 451 is arranged in a V shape, and the V-shaped opening of the release paper 451 is arranged toward the port direction of the adhesive paper 45.

The cleaning assembly 5 includes a fixing frame 51 fixedly connected to the mounting frame 11, a first cylinder 52 fixedly connected to the fixing frame 51, a fixing plate 53 connected to the output end of the first cylinder 52, a cleaning plate 54 connected to the fixing plate 53, a second cylinder 55 fixedly connected to the fixing plate 53, and a clamping plate 56 connected to the output end of the second cylinder 55.

[0065] Reference Figure 7The first cylinder 52 is arranged perpendicular to the direction of the conveyor belt 14, and the second cylinder 55 is arranged perpendicular to the first cylinder 52. The second cylinder 55 pushes the clamping plate 56 to move toward the direction of the cleaning plate 54 until it abuts against the cleaning plate 54.

[0066] Reference Figure 7 One end of the cleaning plate 54 away from the fixing plate 53 is provided with a chamfer, and the chamfer is located on the side of the cleaning plate 54 close to the clamping plate 56.

[0067] Reference ​ The cleaning plate 54 is used to be inserted into the V-shaped opening of the release paper 451 to remove the adhesive paper 45 located on the outermost side of the rotating drum 44 and covered with debris.

[0068] The working principle of the embodiment is as follows: when the corrugated cardboard is conveyed on the conveyor belt 14, the drive motor 31 drives the drive gear 32 to rotate, and drives the driven gear 33 meshing with it to rotate, so that the rack 211 drives the push rod 21 to move along the conveying direction of the corrugated cardboard. When the push rod 21 moves, the interference block on the push rod 21 interferes with the protrusion 23, driving the drive rod and the vibration rod 22 to flip around the hinge point, causing the vibration block 221 on the vibration rod 22 to hit the bottom of the corrugated cardboard, so that the debris at the bottom of the corrugated cardboard falls into the chip collecting trough 19;

[0069] At the same time, the first motor 42 drives one of the rotating drums 44 to rotate above the corrugated cardboard, and the second motor 431 drives the rotating drum 44 to rotate. The rotating drum 44 rotates in the direction of conveying the corrugated cardboard. The adhesive paper 45 on the rotating drum 44 sticks the debris on the surface of the corrugated cardboard to the surface. When there is a lot of debris on the surface of the adhesive paper 45, the first motor 42 drives the rotating rod 43 to rotate, and rotates the rotating drum 44 covered with debris to separate from the corrugated cardboard. When the rotating drum 44 moves below the cleaning plate 54, the first cylinder 52 drives the cleaning plate 54 to be inserted into the V-shaped opening of the release paper 451. The second cylinder 55 pushes the clamping plate 56 to contact the cleaning plate 54 to clamp the release paper 451. Then the second motor 431 drives the rotating drum 44 to rotate until the release paper 451 on the outside is separated from the rotating drum 44, and the staff can remove the torn release paper 451.

[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
