Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, and specifically relates to a trimming device for carton production. Background Art

[0002] Cartons are widely used packaging products. According to different materials, they can be divided into corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models; cartons are composed of cardboard, and the corners of the cardboard need to be cut during the production and processing to ensure that the size of each carton is consistent.

[0003] A large amount of waste paper is generated during the cutting process. When the waste paper accumulates, it occupies a large amount of space, thus affecting the production efficiency. The recycling value of a single piece of waste paper is relatively low and it is not easy to be extruded, which is not conducive to the collection and reuse of waste paper. At the same time, during the extrusion and recycling process of waste paper, excessive dust is easily generated, and these dusts are easily dispersed into the air, causing environmental pollution and also affecting the health of workers. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a trimming device for carton production, which solves the problem that the trimming waste is not easy to recycle.

[0007] The trimming mechanism is installed above the working platform. The trimming mechanism includes a bracket and a mounting seat. The bracket is fixedly connected to the upper end surface of the working platform. The mounting seat is fixedly connected to the bracket. The mounting seat is fixedly connected with a first linear driving rod. The bottom end of the first linear driving rod is connected with a cutting tool. The first linear driving rod enables the cutting tool to move up and down in the vertical direction;

[0008] The crushing mechanism is installed in the machine shell. The crushing mechanism includes a dust reduction component and a first crushing roller and a second crushing roller which are symmetrically arranged left and right. The first crushing roller and the second crushing roller are rotatably connected to the side wall of the machine shell.

The third linear driving rod controls the top plate to move vertically;

[0010] A material guiding groove penetrating the working platform in the vertical direction is also provided.

[0011] Preferably, the crushing mechanism further includes a motor, as well as a driving gear, a reduction gear, a first gear and a second gear that are meshed in sequence. The driving gear, the reduction gear, the first gear and the second gear are rotatably arranged on the side wall of the machine shell. The first gear is coaxially connected to the first crushing roller, the second gear is coaxially connected to the second crushing roller, and the driving gear is connected to the motor.

[0012] Preferably, the dust reduction assembly includes a nozzle and a water delivery pipe that are communicated. The nozzle is directly opposite to the lower sides of the first crushing roller and the second crushing roller.

[0013] Preferably, the working platform is provided with a first positioning assembly. The first positioning assembly includes an adjusting rod, a fixed seat, a hand wheel and a first positioning plate. The first positioning plate is slidably arranged on the working platform. The adjusting rod is threadedly connected to the fixed seat. One end of the adjusting rod is rotatably connected to the first positioning plate, and the other end is fixedly connected to the hand wheel. By rotating the hand wheel, the first positioning plate moves in a direction close to or away from the cutting tool.

[0014] Preferably, the working platform is further provided with a second positioning assembly. The second positioning assembly includes a second positioning plate and a slide rail. The second positioning plate is perpendicular to the first positioning plate. One end of the slide rail is fixedly connected to the second positioning plate, and the other end is slidably connected to the first positioning plate. By moving the slide rail, the second positioning plate moves in a direction close to or away from the first positioning plate. The first positioning plate is threadedly connected with a fastener, and the fastener abuts against the slide rail.

[0015] Preferably, scales are arranged on the upper end face of the working platform corresponding to the positions of the first positioning plate and the second positioning plate.

[0032] As shown in the attached Figures 1-4 A trimming device for carton production shown in the figure includes a housing 1 and a working platform 11 provided at the top of the housing 1. The device is also provided with a trimming mechanism and a crushing mechanism;

[0033] The trimming mechanism is installed above the working platform 11. The trimming mechanism includes a bracket 21 and a mounting seat 22. The bracket 21 is fixedly connected to the upper end surface of the working platform 11. The mounting seat 22 is fixedly connected to the bracket 21. The mounting seat 22 is fixedly connected with a first linear drive rod 221. The bottom end of the first linear drive rod 221 is connected with a cutting tool 222. The first linear drive rod 221 moves the cutting tool 222 up and down in the vertical direction;

[0034] The crushing mechanism is installed in the housing 1. The crushing mechanism includes a dust reduction component and symmetrically arranged first crushing roller 31 and second crushing roller 32 on the left and right. The first crushing roller 31 and the second crushing roller 32 are rotatably connected to the side wall of the housing 1. The dust reduction component is located below the first crushing roller 31 and the second crushing roller 32;

[0035] A compression chamber 5 is provided below the crushing mechanism, and a compression mechanism is provided at the corresponding position of the compression chamber 5. The compression mechanism includes a second linear drive rod 61 and a third linear drive rod 62. The second linear drive rod 61 is connected to a compression push plate 611, and the second linear drive rod 61 controls the compression push plate 611 to move horizontally. The third linear drive rod 62 is connected to a top plate 621, and the third linear drive rod 62 controls the top plate 621 to move vertically.

[0036] A material guiding groove 4 is also provided, which penetrates the working platform 11 in the vertical direction.

[0037] In some embodiments, the first, second, and third linear drive rods can be hydraulic drive rods, pneumatic drive rods, or electric push rods.

[0038] In some embodiments, a first material guiding plate 8 is provided between the material guiding groove 4 and the first crushing roller 31 and the second crushing roller 32. The first material guiding plate 8 guides the cut paper edge waste into the crushing area between the first crushing roller 31 and the second crushing roller 32. A second material guiding plate 9 is provided between the first crushing roller 31 and the second crushing roller 32 and the compression chamber 5. The second material guiding plate 9 guides the crushed waste to the compression chamber 5.

[0039] Further, the crushing mechanism further includes a motor 34, and a driving gear 341, a reduction gear 342, a first gear 311, and a second gear 321 that are sequentially engaged. The driving gear 341, the reduction gear 342, the first gear 311, and the second gear 321 are rotatably provided on the side wall of the machine housing 1. The first gear 311 is coaxially connected to the first crushing roller 31, the second gear 321 is coaxially connected to the second crushing roller 32, and the driving gear 341 is connected to the motor 34.

[0040] In some embodiments, the dust reduction assembly includes a nozzle 331 and a water delivery pipe 332 that are connected. The water delivery pipe 332 sprays water from the nozzle 331, thereby forming a water mist below the first crushing roller 31 and the second crushing roller 32. Then, various sized dust particles below the first crushing roller 31 and the second crushing roller 32 are quickly adsorbed by the water mist, effectively controlling dust emission, preventing excessive dust from spreading into the environment and causing pollution. At the same time, the crushed waste can also be sprayed and wetted to soften the waste and improve the adhesion between the wastes, facilitating the compression of the waste.

[0041] In some embodiments, the working platform 11 is provided with a first positioning component. The first positioning component includes an adjusting rod 72, a fixed seat 73, a handwheel 74 and a first positioning plate 71. The first positioning plate 71 is slidably arranged on the working platform 11. The adjusting rod 72 is threadedly connected to the fixed seat 73. One end of the adjusting rod 72 is rotatably connected to the first positioning plate 71, and the other end is fixedly connected to the handwheel 74. When in use, first rotate the handwheel 74 to drive the adjusting rod 72 to rotate. Under the action of the thread of the fixed seat 73, the rotational motion of the adjusting rod 72 is converted into a linear motion, so that the first positioning plate 71 moves to a suitable position in the direction close to or away from the cutting tool 222. Furthermore, the left and right positions of the cardboard are determined by the first positioning plate 71, and it is ensured that the cardboard will not move during the cutting process, thereby improving the cutting accuracy.

[0042] In some embodiments, the working platform 11 is further provided with a second positioning component. The second positioning component includes a second positioning plate 75 and a slide rail 76. The second positioning plate 75 is perpendicular to the first positioning plate 71. One end of the slide rail 76 is fixedly connected to the second positioning plate 75, and the other end is slidably connected to the first positioning plate 71. By moving the slide rail 76, the second positioning plate 75 moves in the direction close to or away from the first positioning plate 71. The first positioning plate 71 is threadedly connected with a fastener 711. When it is necessary to lock the slide rail 76, rotate the fastener 711 so that the fastener 711 abuts against the slide rail 76, generating an extrusion force, thereby locking the slide rail 76. Furthermore, the front and back positions of the cardboard are determined by the second positioning plate 75, and it is ensured that the cardboard will not move during the cutting process, further improving the cutting accuracy.

[0043] In some embodiments, a scale 10 is arranged on the upper end surface of the working platform 11. The cardboard can be accurately positioned in cooperation with the first positioning plate 71 and the second positioning plate 75.

[0044] In some embodiments, a pressure sensor 6111 is arranged between the compression push plate 611 and the second linear drive rod 61 to obtain the pressure during the process of compressing the waste material, reflecting the compression condition of the waste material in the compression chamber 5, which helps to avoid damage to the compression chamber 5 or the top plate 621 caused by excessive pressure.

[0045] When it is necessary to compress the waste material, start the second linear drive rod 61. At this time, the top plate 621 blocks the outlet of the compression chamber 5. The second linear drive rod 61 pushes the compression push plate 611 to move in the direction close to the outlet of the compression chamber 5, thereby squeezing the waste material until the pressure sensor 6111 reaches a preset value, and then the second linear drive rod 61 stops moving.

[0046] When it is necessary to clean up the compressed waste, start the third linear drive rod 62. The third linear drive rod 62 pushes the top plate 621 to move upward, opening the outlet of the compression chamber 5. At this time, start the second linear drive rod 61 again, so that the compression push plate 611 moves in the direction of the outlet of the compression chamber 5 until the compressed waste block is pushed out of the compression chamber 5.

[0047] The working principle of the present utility model is as follows:

[0048] The operator places the cardboard on the working platform 11, adjusts the first positioning plate 71 to a suitable position by rotating the handwheel 74 in cooperation with the scale 10, then moves the slide rail 76 in cooperation with the scale 10 to adjust the second positioning plate 75 to a suitable position, and rotates the fastener 711 to lock the slide rail 76; after positioning the cardboard by the first positioning plate 71 and the second positioning plate 75, drive the cutting tool 222 to move downward by the first linear drive rod 221, so that the cutting tool 222 abuts against the end face of the cardboard for edge cutting operation;

[0049] The cut waste enters below the working platform 11 through the material guide groove 4, and is guided into the crushing area of the first crushing roller 31 and the second crushing roller 32 by the first material guide plate 8. The operator turns on the motor 34, and the output end of the motor 34 rotates clockwise. Driven by the output end of the motor 34, the driving gear 341 can rotate, so that the reduction gear 342 rotates driven by the driving gear 341. Subsequently, the reduction gear 342 drives the first gear 311 to rotate, and the first gear 311 further drives the second gear 321 to rotate, finally making the first crushing roller 31 rotate clockwise along its axis, and the second crushing roller 32 rotate counterclockwise along its axis to crush the waste;

[0050] During the crushing process, the dust reduction component is in an open state, water flows from the water delivery pipe 332 into the nozzle 331, and the nozzle 331 sprays water below the first crushing roller 31 and the second crushing roller 32, so that through spraying, the dust raised during the crushing of the waste is effectively adsorbed;

[0051] The crushed waste enters the compression chamber 5 under the guiding action of the second material guide plate 9.

[0052] When the waste material in the compression chamber 5 accumulates to a certain extent, the operator activates the second linear drive rod 61 to drive the compression push plate 611 to move towards the outlet of the compression chamber 5. The crushed waste material is pushed by the compression push plate 611 towards the outlet of the compression chamber 5, and the crushed waste material contacts the top plate 621. At this time, the top plate 621 closes the outlet of the compression chamber 5, and the compression push plate 611 continues to move towards the outlet of the compression chamber 5, thereby continuing to compress the waste material in the compression chamber 5. When the value of the pressure sensor 6111 reaches the set value, the second linear drive rod 61 pauses. At this time, the waste material has been fully compressed. Subsequently, the third linear drive rod 62 is activated to drive the top plate 621 to move upward to open the outlet of the compression chamber 5. When the top plate 621 is at the highest point of the stroke, the second linear drive rod 61 is activated again to drive the compression push plate 611 to move towards the outlet of the compression chamber 5 until the compressed waste material block is pushed out of the compression chamber 5. At this time, the compression push plate 611 is at the farthest end of the stroke;

[0053] When the waste material leaves the compression chamber 5, the second linear drive rod 61 is activated to drive the compression push plate 611 to move away from the outlet of the compression chamber 5 until it reaches the nearest end of the stroke; when the second linear drive rod 61 is at the nearest end of the stroke, the third linear drive rod 62 is activated to drive the top plate 621 to move downward until the top plate 621 is at the lowest point of the stroke to close the outlet of the compression chamber 5, thus entering the next working cycle.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
