Description

Technical Field

[0001] The invention relates to the field of corrugated paperboard processing, and in particular to processing equipment for improving the strength of paperboard. Background Art

[0002] Corrugated paper is a multi-layer adhesive body, as shown in the attached instructions. Figure 1 As shown, it is composed of at least one layer of corrugated core paper sandwich and one layer of surface paper 6 bonded together, has high mechanical strength, can withstand collision and fall during transportation, so it is mostly used to manufacture corrugated paper boxes for transportation.

[0003] The above-mentioned prior art has the following defects: when producing corrugated paper boxes, after the surface paper and the core paper are bonded together, a slotting process is required to cut out the folding lines of the upper cover and the lower cover of the paper box, and finally fold it into a corrugated paper box. The slotting of traditional corrugated paper boxes reduces the overall strength of the paperboard, and it is easy to regain moisture after being frozen, causing the paper box to crack and collapse. This problem needs to be solved urgently. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a processing equipment for improving the strength of cardboard, which has the effect of adding reinforcement lines on the surface paper, improving the strength of the surface paper and the corrugated core paper connected to form corrugated paper, and effectively preventing the carton made of corrugated paper from cracking and collapsing.

[0005] A processing device for improving the strength of paperboard, comprising a feeding part and a processing part, wherein the processing part comprises a frame, a rubber roller and a plurality of paper guide rollers are installed in parallel on the frame, a paper reel is arranged on one side of the frame, the setting direction of the paper reel is parallel to the setting direction of the paper guide roller, the surface paper for processing the corrugated paperboard is placed on the paper reel, the end of the surface paper passes around each paper guide roller in turn from top to bottom and contacts with the rubber roller;

[0006] The feeding part comprises a frame, on which a plurality of mounting posts for placing reinforcing wire coils are arranged in a vertical direction, and a wire coil is mounted on the frame, through which the end of the reinforcing wire passes, bypasses the rubber roller and is bonded to the surface paper.

[0007] By adopting the above technical scheme, the rolled facial paper is placed on a paper winder, the reinforcing wire is placed on a mounting column, one end of the facial paper is passed around a plurality of paper guide rollers and a rubber roller in sequence, the reinforcing wire is also passed around a plurality of paper guide rollers and adhered to the facial paper at the rubber roller, the facial paper and the reinforcing wire are bonded together by applying glue on the rubber roller, the paper winder drives the rolled facial paper to rotate through a motor, and the reinforcing wire is bonded together along the length direction of the facial paper, thereby enhancing the strength of the facial paper, and then enhancing the strength of the corrugated paper, thereby reducing the collapse of the corrugated paper box.

[0008] The present invention is further configured as follows: a mounting plate and a guide plate are connected to the frame, the mounting plate is fixedly mounted below the guide plate, the mounting posts are evenly fixed on the mounting plate, and the guide plate is provided with a guide hole just above each mounting post;

[0009] The frame is fixedly connected to one side close to the frame with two guide rods which help the reinforcing wire to keep in a straight state.

[0010] By adopting the above technical solution, after placing the reinforcing wire coil on the mounting column, the end of the reinforcing wire is pulled out and passed through the guide hole, and then bypasses the two guide rods, and then the reinforcing wire is bonded to the surface paper through the rubber roller.

[0011] The present invention is further configured as follows: a plurality of guide posts are fixedly connected to the frame in a horizontal direction between the guide hole and the guide rod, and the reinforcement line passes between two guide posts.

[0012] By adopting the above technical solution, a single reinforcement wire passes through the guide hole and then passes between two guide pillars. When multiple reinforcement wires need to be pasted in parallel on the surface paper, the setting of the guide pillars can effectively prevent the reinforcement wires from getting tangled at the feeding part.

[0013] The present invention is further configured as follows: a plurality of guide rings for a single reinforcing wire to pass through are fixed in parallel on the frame between the guide coil and the paper guide roller.

[0014] By adopting the above technical solution, after the reinforcing wire passes through the conductor ring, the single reinforcing wire is passed through the guide ring in sequence, so that multiple reinforcing wires can be kept parallel to each other and bonded to the surface paper, which has a good guiding effect.

[0015] The present invention is further configured as follows: sliding bars are fixedly connected to the opposite sides of the mounting plate, a sliding groove adapted to the sliding bar is opened on the frame, the sliding bar is embedded in the sliding groove, and the sliding bar and the sliding groove are slidingly connected, and the notch of the sliding bar extends to the side wall of the frame.

[0018] By adopting the above technical solution, the dovetail-shaped sliding bar is not easy to move out of the sliding groove when it is embedded in the sliding groove, and the structure is relatively stable.

[0019] The present invention is further configured as follows: a positioning rod is fixedly connected to the side of the frame close to the paper reel, and the surface paper passes between the positioning rod and the paper guide roller close to the side of the paper reel.

[0020] By adopting the above technical solution, when one end of the tissue paper is pulled out and passes around multiple paper guide rollers, the tissue paper passes under the positioning rod, and the tissue paper is located above the paper guide roller, so that the subsequent tissue paper passes through the multiple paper guide rollers in sequence.

[0021] The present invention is further configured such that: three-level observation steps are formed on one side of the paper reel.

[0022] By adopting the above technical solution, since the rubber roller is installed at a higher position, when the whole machine is opened, the operator first stands on the top of the paper reel through the three-level observation steps to apply glue on the rubber roller and clean the rubber roller after shutdown. The integrated design of the steps and the paper reel makes the operation more convenient.

[0023] The present invention is further configured as follows: four pulleys are respectively installed at the four corners of the bottom wall of the mounting plate.

[0024] By adopting the above technical solution, the setting of the pulley can move the entire feeding part according to the needs of the production site.

[0025] The present invention is further configured as follows: a hand-held portion is fixedly connected to the side wall of the mounting plate.

[0026] By adopting the above technical solution, when the reinforcing wire coil needs to be replaced, the setting of the hand-held part makes it easy to pull the mounting plate so that it is staggered with the guide plate by a certain distance, further simplifying the replacement process.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. The feeding part for placing the reinforcement line and the processing part for bonding the reinforcement line to the surface paper can effectively improve the strength of the surface paper and enhance the structural stability of the finished corrugated board;

[0029] 2. The setting of guide posts and guide rings can effectively maintain the parallel relationship between the reinforcement lines, making it difficult for the reinforcement lines to get tangled;

[0030] 3. The mounting plate connected to the frame by sliding strips embedded in the sliding grooves facilitates the replacement of the reinforcement wire. BRIEF DESCRIPTION OF THE DRAWINGS
