Description

Technical Field

[0001] This utility model relates to the technical field of grooving line devices, and in particular to a precision grooving line device for carton processing. Background Technology

[0002] A precision slotting line device for carton processing is a specialized processing equipment used in the carton production process to cut precise depth, width, and length slots at specific locations on cardboard, providing pre-fold lines for carton folding. It can be summarized as follows: composed of a feeding mechanism, positioning components, slotting cutter set, depth adjustment system, and control system, it is an automated processing device that cuts continuous or intermittent slots on substrates such as corrugated cardboard and hardboard through mechanical transmission and CNC technology, ensuring neat fold lines and precise angles when the carton is folded.

[0003] While existing precision slotting line devices for cardboard box processing can achieve precise cutting of the slots, they have significant drawbacks in handling waste paper strips after slotting. The most prominent issue is that waste paper strips are transported simultaneously with the cardboard boxes, leading to difficulties in subsequent sorting, increased labor costs, and potential production risks. When cardboard boxes are stacked, waste paper strips may be trapped between boxes or embedded in the folds of the boxes, forming hidden residues. During manual sorting, the stacked cardboard boxes must be disassembled and inspected one by one, and then the waste paper strips must be manually peeled off. This not only consumes a lot of manpower but also disrupts the stacking order of the cardboard boxes, increasing the workload of secondary sorting. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a precise slotting line device for carton processing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a precision slotting line device for carton processing, comprising a plurality of symmetrically arranged support columns and a slotting machine body. A belt conveyor and a slitting belt conveyor are fixedly installed between the plurality of support columns. The slitting belt conveyor is located above the belt conveyor. The output end of the slotting machine body corresponds to the input end of the slitting belt conveyor. A support frame is fixedly installed on the frame of the slitting belt conveyor by bolts. A U-shaped frame is fixedly connected to the top of the support frame. A cylinder is fixedly connected to the top of the U-shaped frame. A lifting plate is fixedly connected to the output end of the cylinder. Two symmetrically arranged springs are fixedly connected to the bottom surface of the lifting plate. An arc-shaped pressure plate is fixedly connected to the bottom end of the two springs. A fan mounting plate is fixedly connected inside the support frame. A plurality of linear array fans are embedded inside the fan mounting plate.

[0007] Preferably, of any of the above solutions, a dustproof net is fixedly installed on the top of the support frame by bolts, and the input ends of several of the fans correspond to the dustproof net.

[0008] Preferably, in any of the above solutions, two symmetrically arranged baffles are fixed inside the support frame, and two symmetrically arranged locking pins are fixedly connected to the bottom surface of each baffle. Several locking pins are engaged with the frame of the slitting belt conveyor.

[0009] Preferably, in any of the above solutions, the top of the arc-shaped pressure plate is fixedly connected to two symmetrically arranged limiting posts, the two limiting posts are respectively located inside the two springs, and both limiting posts are slidably connected to the lifting plate.

[0010] Preferably, in any of the above solutions, the top surface of the lifting plate is fixedly connected to two symmetrically arranged guide rods, and both guide rods are slidably connected to the U-shaped frame.

[0011] Preferably, in any of the above solutions, the top surface of the U-shaped frame has two symmetrically arranged clearance holes, and the two clearance holes correspond to two limiting posts respectively.

[0012] Preferably, in any of the above schemes, the angle between the slit belt conveyor and the belt conveyor is an acute angle, and the output end of the slit belt conveyor is inclined upward.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When the slotted cartons are conveyed by the slitting belt conveyor, the blower is activated. The blower draws in air through the dustproof net, generating airflow. Simultaneously, the cylinder pushes the lifting plate downwards, and the arc-shaped pressure plate, cushioned by the springs, contacts the cartons, initially pressing and positioning them. Subsequently, the airflow generated by the blower acts on the surface and perimeter of the cartons, blowing the waste paper strips generated during slotting away from the cartons. Affected by the airflow, the waste paper strips fall onto the belt conveyor below and are transported to the designated collection area. The airflow generated by the blower can quickly and efficiently separate and blow the waste paper strips off the cartons, preventing them from entering the subsequent stacking process. The arc-shaped pressure plate, in conjunction with the springs, not only holds the cartons in place, ensuring their stable position during airflow cleaning, but also uses the elasticity of the springs to cushion the impact and prevent excessive pressure from damaging the cartons. The dustproof net filters impurities in the air, preventing the blower from drawing in impurities that could affect its performance, and also preventing impurities from being blown onto the cartons by the airflow and causing contamination. This design replaces the traditional method of manually sorting waste paper strips, significantly reducing labor input, lowering sorting costs, while ensuring the orderly stacking of cardboard boxes and improving production efficiency.

[0014] 2. Place the cardboard box to be slotted on the slitting belt conveyor. Multiple narrow belts on the slitting belt conveyor work together to support and transport the cardboard box, preventing it from shifting during transport. When the slotting machine performs the slotting operation, the baffle plate restricts the transport range of the cardboard box, further ensuring accurate positioning during slotting. The guide rod slides within the U-shaped frame, providing guidance for the up-and-down movement of the lifting plate, ensuring the arc-shaped pressure plate acts perpendicularly on the cardboard box. The limiting post slides within the clearance hole and simultaneously within the lifting plate, limiting the compression and extension of the spring, preventing spring skewing, and ensuring uniform force on the arc-shaped pressure plate. The multi-narrow belt design of the slitting belt conveyor enhances the support and positioning of the cardboard box, effectively preventing shifting during transport and ensuring accurate slotting by the slotting machine. The baffle plate, in conjunction with the locking pins, engages with the frame of the slitting belt conveyor, stably limiting the transport range of the cardboard box and further improving the positional accuracy during slotting.

[0025] A precision slotting line device for cardboard box processing, the working principle of which is as follows: 1) When the slotted carton is conveyed by the slitting belt conveyor 4, the fan 12 is started. The fan 12 draws in air through the dustproof net 13 and generates airflow. At the same time, the cylinder 7 pushes the lifting plate 8 down, and the arc-shaped pressure plate 10 contacts the carton under the buffering action of the spring 9 to initially press and position the carton.

[0026] 2): The airflow generated by the fan 12 acts on the surface and periphery of the carton, blowing the waste paper strips generated by the slotting away from the carton. Affected by the airflow, the waste paper strips fall onto the belt conveyor 3 below, and are transported by the belt conveyor 3 to the designated collection area.

[0027] 3): The airflow generated by the fan 12 can quickly and efficiently separate and blow off the waste paper strips from the cardboard box, preventing the waste paper strips from entering the subsequent stacking process with the cardboard box; the arc-shaped pressure plate 10, together with the spring 9, can not only hold the cardboard box, but also ensure that the position of the cardboard box is stable during airflow cleaning.

[0028] In summary, the precision slotting line device for cardboard box processing, when the slotted cardboard box is conveyed by the slitting belt conveyor 4, starts the blower 12. The blower 12 draws in air through the dustproof net 13, generating airflow. At the same time, the cylinder 7 pushes the lifting plate 8 down, and the arc-shaped pressure plate 10 contacts the cardboard box under the buffering effect of the spring 9, performing initial pressing and positioning of the cardboard box. Subsequently, the airflow generated by the blower 12 acts on the surface and periphery of the cardboard box, blowing the waste paper strips generated by slotting away from the cardboard box. Affected by the airflow, the waste paper strips fall onto the belt conveyor 3 below, and are conveyed by the belt conveyor 3 to the designated collection area. The airflow generated by the fan 12 can quickly and efficiently separate and blow off waste paper strips from the cardboard box, preventing waste paper strips from entering the subsequent stacking process with the cardboard box; the arc-shaped pressure plate 10, together with the spring 9, can not only hold the cardboard box, ensuring the stability of the cardboard box position during airflow cleaning, but also use the elasticity of the spring 9 to buffer and prevent excessive pressure from damaging the cardboard box; the dustproof net 13 can filter impurities in the air, preventing the fan 12 from sucking in impurities and affecting its working performance, and also preventing impurities from being blown onto the cardboard box by the airflow and causing pollution. This design replaces the traditional manual sorting of waste paper strips, significantly reducing labor input and sorting costs. It also ensures orderly cardboard box stacking and improves production efficiency. Cardboard boxes to be slotted are placed on a slitting belt conveyor 4. Multiple narrow belts on the slitting belt conveyor 4 work together to support and transport the cardboard boxes, preventing them from shifting during transport. When the slotting machine body 2 performs slotting operations on the cardboard boxes, the baffle 14 restricts the transport range of the cardboard boxes, further ensuring accurate positioning during slotting. The guide rod 17 slides within the U-shaped frame 6, providing guidance for the up-and-down movement of the lifting plate 8, ensuring that the arc-shaped pressure plate 10 acts vertically on the cardboard box. The limiting post 16 slides within the clearance hole 18 and simultaneously within the lifting plate 8, limiting the compression and extension of the spring 9, preventing the spring 9 from tilting, and ensuring that the arc-shaped pressure plate 10 is subjected to uniform force. The multi-narrow belt design of the slitting belt conveyor 4 enhances the support and positioning of the carton, effectively preventing the carton from shifting during transport and ensuring the precise slotting of the slotting machine body 2.
