Description

Technical Field

[0001] The present invention relates to the technical field of general crushing, and more particularly, to a recycling raw material crushing device for corrugated cardboard boxes manufacturing. Background Art

[0002] Corrugated cardboard is made into corrugated cardboard boxes through die-cutting, indentation, stapling or gluing. Corrugated cardboard boxes are the most widely used packaging products, and their usage has always led among various packaging products. For more than half a century, corrugated cardboard boxes have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, becoming the main force of transportation packaging. In addition to protecting goods, facilitating storage and transportation, it also plays a role in beautifying and promoting goods. Corrugated cardboard boxes are green environmental protection products, which are beneficial to environmental protection and handling and transportation.

[0003] With the extensive use of corrugated cardboard boxes, a large number of waste corrugated cardboard boxes are generated. With the enhancement of environmental awareness and the deepening of the concept of sustainable development, the recycling and reuse of corrugated cardboard boxes have become an inevitable trend in the industry's development. After the recycled corrugated cardboard boxes are crushed, they can be used as recycled pulp raw materials for manufacturing corrugated cardboard boxes to produce new corrugated cardboard, thus realizing the recycling of resources.

[0004] Crushing the recycled corrugated cardboard is to make the waste paper particles smaller and more uniform, which is beneficial to the penetration and reaction of subsequent chemical agents, improve the efficiency of deinking and pulping, and is to better disperse the fibers in the waste paper to avoid fiber agglomeration, thereby improving the utilization rate of fibers and the quality of recycled paper. However, in the actual crushing process, there are some problems. After use, the corrugated cardboard boxes are often adhered with impurities such as tape, which increases the toughness of the corresponding parts of the corrugated cardboard. Therefore, traditional crushing devices are difficult to effectively crush, resulting in low crushing efficiency, affecting the production efficiency of subsequent recycled pulp, and the impurities such as tape remaining in the crushed waste paper will affect the purity of the recycled pulp; at the same time, the particle size uniformity of the traditional crushing device after crushing is poor, thus affecting the effects of subsequent pulping and deinking processes; furthermore, impurities such as tape and the crushed waste paper blocks are easily wound and accumulated on the blades or rotors of the crushing device, especially the blade-type crusher, resulting in equipment jamming or shutdown, and frequent cleaning and maintenance are required.

[0065] The driving of the pretreatment mechanism 4 enables the fixation of the corrugated cardboard and the scraping of its outer surface to remove impurities on the outer surface of the corrugated cardboard;

[0066] The pretreatment mechanism 4 is adapted to sequentially transfer several corrugated cardboard to the crushing part 3 to stack the corrugated cardboard in an orderly manner;

[0067] The driving heat assistance mechanism 5 can heat the outer surface of the corrugated cardboard to obtain a softening measure to assist the pretreatment mechanism 4 in impurity removal. The recycling raw material crushing device for corrugated cardboard manufacturing can first finely cut the recycled corrugated cardboard through the crushing part 3, so as to first cut and crush the corrugated cardboard into uniformly sized fragments, and then continuously cut and crush the waste paper fragments again. While ensuring the crushing effect and ensuring that the corrugated cardboard can be crushed into waste paper fragments meeting the size requirements, the uniformity of the crushing particle size is ensured, thereby ensuring the effects of subsequent pulping and deinking processes. Through the pretreatment mechanism 4, the outer surface of the corrugated cardboard to be crushed can be vigorously scraped, so as to remove the impurities adhered to the corrugated cardboard, especially the tape, ensuring the cleanliness of the corrugated cardboard, thereby preventing the increase in crushing difficulty caused by the presence of the tape, ensuring that the crushing of the recycled corrugated cardboard can be completed quickly and with high quality, and ensuring the purity of the subsequent generated recycled pulp. Through the heat assistance mechanism 5, the outer surface of the corrugated cardboard can be quickly heated before the pretreatment mechanism 4 processes the impurities, so that its temperature rises rapidly, thereby softening the adhesive in the tape and making it easier to remove, and then improving the actual effect of the pretreatment mechanism 4 through an auxiliary means to ensure that the tape is completely removed. The recycling raw material crushing device for corrugated cardboard manufacturing can quickly stack multiple corrugated cardboards orderly and crush them batch by batch under the combined action of the pretreatment mechanism 4 and the crushing part 3, so as to ensure the crushing efficiency and then improve the production efficiency of the entire recycled pulp. The recycling raw material crushing device for corrugated cardboard manufacturing does not use a rotating blade as a crushing means.

[0071] Driving the cylinder 36 can vertically push down the cutting piece 38 through the connecting plate 37, so as to fit the cutting piece 38 into the square processing groove 32. After the corrugated cardboard in the square processing groove 32 is stacked to a certain number, the driving cylinder 36 pushes the cutting piece 38 straight downwards. Using the thrust of the cylinder 36 and the sharpness of the cutting piece 38 to cut the corrugated cardboard below. After the cutting piece 38 completes a single cut and reversely drives the cylinder 36 to drive the cutting piece 38 to reset, immediately drive the electric cylinder 39 to push the outer positioning kit 35 and the cylinder 36 forward a little, and then drive the cylinder 36 to cut again, and so on until all the slitting in this direction of the stacked corrugated cardboard below is completed, breaking the corrugated cardboard into long strips. Then, rotate the direction of the square processing groove 32 through the lower driving seat 31 by ninety degrees, and then perform cutting and breaking again, so as to ensure the crushing of the recycled corrugated cardboard; the control precision of the electric cylinder 39 is high, and it can push the outer positioning kit 35 and the cylinder 36 forward with a weak amplitude each time, so as to ensure the fineness of the crushing, and at the same time ensure the uniformity of each slitting, so that the waste paper blocks first have a particle size within the allowable range, ensure the uniformity of crushing, and then ensure the effect of subsequent pulping and deinking processes.

[0072] Optionally, the lower driving seat 31 includes a counterweight 311, and there is a cylinder in the center of the counterweight 311.

The driving motor 315 directly drives the driving gear 316 to rotate, and then the driving gear 316 drives the circular pillar 312 to rotate on the counterweight 311 through the driven gear 314, so as to ensure that the square processing groove 32 can be rotated to turn the angle of the corrugated cardboard in the square processing groove 32, making it rotate by ninety degrees, and then ensuring that the slitting and crushing of the corrugated cardboard can be fully completed and broken into pieces.

[0075] Optionally, convex edges 21 are respectively arranged on the front and rear sides of the support platform 2;

[0076] The preprocessing mechanism 4 includes a frame rod 41 slidably inserted on the two convex edges 21, and the middle part of the frame rod 41 is in contact with the right side surface of the support platform 2. Two second groove members 42 are spaced and installed on the table 1, and the two second groove members 42 extend to the right. Two connecting plates 43 are respectively slidably installed in the two second groove members 42, and the top surfaces of the two connecting plates 43 are respectively connected to the bottom surfaces on the front and rear sides of the frame rod 41. A first electric push rod 44 is arranged on the table 1, and the output end of the first electric push rod 44 is connected to the right end surface of the front connecting plate 43. A fixed-point strip plate 45 is fixedly installed on the front side of the frame rod 41, a clamping strip plate 46 is placed on the rear side of the frame rod 41, a convex edge platform 47 is installed on the frame rod 41, a second electric push rod 48 is arranged on the convex edge platform 47, and the output end of the second electric push rod 48 is connected to the back of the clamping strip plate 46. A cushion table 49 is arranged on the table 1 and on the left side of the support platform 2, a third electric push rod 491 is installed on the cushion table 49, an intermediate strip plate 492 is connected to the output end of the third electric push rod 491, a plurality of swing arms 493 are equally spaced and hinged on the front side surface of the intermediate strip plate 492, a pointed-edge scraping strip 494 is connected to the front ends of the plurality of swing arms 493, and a swing cylinder 495 is installed on the intermediate strip plate 492, and the output end of the swing cylinder 495 is connected to one of the plurality of swing arms 493;

[0077] The two second groove members 42 are respectively located on the front and rear sides of the square processing groove 32;

[0078] The front side of the sharp-edge scraping strip 494 faces the support platform 2. Place the corrugated cardboard on the support platform 2 with one side against the fixed-point strip 45, making the outer surface of the corrugated cardboard, i.e., the side with impurities such as adhesive tape, face upward. Then drive the second electric push rod 48 to push the clamping strip 46 forward until the clamping strip 46 abuts against the corrugated cardboard, clamping the corrugated cardboard between the clamping strip 46 and the fixed-point strip 45 to complete the fixation of the corrugated cardboard. Then drive the third electric push rod 491 to push the middle strip 492 and several swing arms 493 forward, so that the sharp-edge scraping strip 494 reaches above the corrugated cardboard. Then drive the swing cylinder 495 to swing several swing arms 493 downward until the sharp-edge scraping strip 494 is pressed on the corrugated cardboard, making the sharp-edge scraping strip 494 in a state of slightly pressing a mark on the corrugated cardboard. Then continue to drive the third electric push rod 491 to continuously push the sharp-edge scraping strip 494 forward horizontally until the movement route of the sharp-edge scraping strip 494 covers the surface of the corrugated cardboard, and then reverse-drive the third electric push rod 491 to reset the sharp-edge scraping strip 494. Thus, in this process, the moving sharp-edge scraping strip 494 strongly scrapes the outer surface of the corrugated cardboard to shovel off the impurities, especially the adhesive tape, adhering to the corrugated cardboard, ensuring the cleanliness of the corrugated cardboard, and further preventing the increase in the difficulty of crushing due to the presence of the adhesive tape, ensuring that the recycled corrugated cardboard can be crushed quickly and with high quality, and ensuring the purity of the subsequent generated recycled pulp; the downward pressure of the swing cylinder 495 on the sharp-edge scraping strip 494 enables the sharp-edge scraping strip 494 to obtain a greater force exerted on the corrugated cardboard, ensuring that during the scraping process of the sharp-edge scraping strip 494, impurities such as adhesive tape can be lifted, thus obtaining a better cleaning effect; after cleaning the corrugated cardboard, drive the first electric push rod 44 to push the connecting plate 43 connected to it forward along the second groove member 42, thereby pushing the entire frame rod 41 and gradually separating it from the support platform 2.
