Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard, and in particular to a corrugated carton processing technology. Background Technology

[0002] Corrugated cardboard boxes are three-dimensional packaging containers formed from corrugated cardboard through processes such as die-cutting, creasing, stapling, or gluing. They are made by laminating shaped core paper and linerboard, providing not only excellent protection, cushioning, and stretchability, but also a certain aesthetic appeal. For over half a century, corrugated cardboard boxes have gradually replaced wooden crates and other transport packaging containers, becoming the preferred choice for transport packaging due to their superior performance and easy processing. However, the core paper in corrugated cardboard is relatively thin, lacking sufficient support, while a thicker core paper would require a large amount of raw material after folding. Summary of the Invention

[0003] The purpose of this invention is to provide a corrugated cardboard box processing technology that uses processing equipment to process waste paper into paper tubes to serve as the core paper in corrugated cardboard, which can be recycled and reused, and has sufficient supporting strength.

[0004] The objective of this invention is achieved through the following technical solution:

[0006] Step 1: Put the waste paper into the processing equipment to shred it;

[0007] Step 2: Mix the waste paper with the adhesive;

[0008] Step 3: Squeeze out the excess glue from the waste paper and make waste paperboard;

[0009] Step 4: Roll the waste cardboard into a tube;

[0010] Step 5: Glue the paper tube to the linerboard to form corrugated cardboard.

[0011] The processing equipment includes a forming disc, a central column and three pressure plates are slidably connected inside the forming disc, and a spring is fixed between each pressure plate and the forming disc. A first rotary motor is provided between the central column and the forming disc.

[0012] Two sliding pillars are fixedly connected to the forming plate, and a demolding plate is slidably connected between the two sliding pillars. Three rollers are rotatably connected to the forming plate. A pull rope is fixedly connected between each pressure plate and the demolding plate, and each pull rope is in contact with the corresponding roller. A third electric push rod is provided between the central pillar and the forming plate.

[0013] The processing equipment also includes a crushing box, in which two crushing rollers are rotatably connected. A second rotary motor is installed between one of the crushing rollers and the crushing box, and the two crushing rollers are meshed and driven together. Attached Figure Description

[0031] like Figure 11 and Figure 12 As shown:

[0032] A corrugated cardboard box processing technology includes the following steps:

[0033] Step 1: Put the waste paper into the processing equipment to shred it;

[0034] Step 2: Mix the waste paper with the adhesive;

[0035] Step 3: Squeeze out the excess glue from the waste paper and make waste paperboard;

[0036] Step 4: Roll the waste cardboard into a tube;

[0037] Step 5: Glue the paper tube to the linerboard to form corrugated cardboard.

[0038] like Figure 4 and Figure 5 As shown:

[0039] The processing equipment includes a forming disc 201, a central column 202 and three pressure plates 203, all of which are slidably connected inside the forming disc 201. Three springs 206 are respectively fixed between the three pressure plates 203 and the forming disc 201. A first rotary motor is provided between the central column 202 and the forming disc 201.

[0040] One end of the compressed waste cardboard is fixed to the central column 202, thus starting the first rotary motor to work. The first rotary motor drives the central column 202 to rotate within the forming disc 201, which in turn causes the central column 202 to rotate the waste cardboard, thereby winding the waste cardboard onto the central column 202 and processing it into a paper tube. Three springs 206 simultaneously pull the pressure plate 203 to move within the forming disc 201, causing the pressure plate 203 to move closer to the central column 202 simultaneously, thereby compressing the wound waste cardboard in three directions at the same time, making the processed paper tube more compact. The increased compactness allows the corrugated cardboard to withstand greater pressure, thereby improving its quality. As the central column 202 rotates, the outer diameter of the paper tube wound on the central column 202 gradually increases, which in turn pushes the three pressure plates 203 outward, compressing the three springs 206. Each of the three pressure plates 203 is fixedly connected to a displacement sensor between itself and the forming disc 201. When the outer diameter reaches the set value, the paper tube is demolded. If the difference between the three displacement sensor values ​​is too large, it can be determined that the produced paper tube is of uneven thickness, and thus it is processed.

[0041] like Figure 5-7 As shown:

[0042] Both sliding columns 204 are fixedly connected to the forming plate 201, the demolding plate 205 is slidably connected to the two sliding columns 204, three rollers 207 are rotatably connected to the forming plate 201, three pull ropes 208 are respectively fixedly connected between the three pressure plates 203 and the demolding plate 205, each pull rope 208 is in contact with the corresponding roller 207, and a third electric push rod is provided between the central column 202 and the forming plate 201.

[0043] Once the outer diameter of the paper tube meets the requirements, the third electric push rod is activated, causing the central column 202 to move towards the demolding plate 205 within the forming plate 201. The forming plate 201 intercepts the paper tube, thus pulling the central column 202 out of the paper tube and demolding it. As the central column 202 moves, it contacts the demolding plate 205 and subsequently moves the demolding plate 205 backward, causing it to slide on the two sliding pillars 204. This causes the demolding plate 205 to move the three pull ropes 208, which slide on the three rollers 207 respectively. This reduces the friction between the pull ropes 208 and the forming plate 201, allowing the pull ropes 208 to smoothly pull the pressure plate 203 to slide on the forming plate 201. The three pressure plates 203 expand outward simultaneously, causing the paper tube to fall between the three pressure plates 203, thus completing the demolding process.

[0044] like Figure 1 As shown:

[0045] The processing equipment also includes a crushing box 101, with two crushing rollers 102 rotatably connected inside the crushing box 101. A second rotary motor is provided between one of the crushing rollers 102 and the crushing box 101, and the two crushing rollers 102 are meshed and driven together.

[0046] The second rotary motor is driven to operate, thereby driving one shredding roller 102 to rotate, which in turn drives the other shredding roller 102 to rotate through a meshing transmission connection. This causes the two shredding rollers 102 to move in opposite directions, thereby adding waste paper between the two shredding rollers 102. The waste paper is then shredded by the interlocking of the two shredding rollers 102, facilitating further processing of the waste paper and making it easier to process the waste paper into paper tubes.

[0047] like Figure 1 and Figure 2 As shown:

[0048] The impregnation tank 103 is fixedly connected to the bottom of the crushing tank 101. The scraper 104 is fixedly connected to the impregnation tank 103. Two fixing plates 106 are fixedly connected to the impregnation tank 103. A rotating shaft is rotatably connected between the impregnation tank 103 and the two fixing plates 106. The filter belt 105 is set between the two rotating shafts. A third rotating motor is installed in one of the rotating shafts.

[0049] The shredded waste paper falls onto the filter belt 105 and mixes with the adhesive, allowing the adhesive to penetrate the paper fibers. At this time, the third rotary motor is driven to work, which moves the filter belt 105. The upper filter belt 105 moves out of the impregnation tank 103, which in turn moves the waste paper on the filter belt 105 outward. As the waste paper moves outward, it comes into contact with the scraper 104 inside the impregnation tank 103. The scraper 104 squeezes the waste paper, thereby squeezing out the excess adhesive from the waste paper and allowing it to flow down through the filter holes on the filter belt 105. The scraper 104 squeezes the waste paper fragments into thinner waste paperboard, which is then rolled into a paper tube.

[0050] like Figure 2 As shown:

[0051] The scraper 107 is fixed between two fixed plates 106, and the blade of the scraper 107 contacts the filter belt 105. The connecting plate 109 is fixed between one of the fixed plates 106 and the forming disc 201.

[0052] The waste cardboard, after being squeezed by the scraper 104, is still relatively wet and will adhere to the surface of the filter belt 105. A scraper 107 is then fixed between the front ends of the two fixed plates 106, and the blade of the scraper 107 contacts the surface of the filter belt 105. As the waste cardboard passes through the scraper 107, the scraper 107 scrapes the waste cardboard away from the surface of the filter belt 105, thus separating the waste cardboard. The scraped waste cardboard passes over the surface of the scraper 107 and is then fixed to the central column 202. After being wound up by the central column 202, it forms a paper tube. The central column 202 is also equipped with a heating device to dry the inner ring of the paper tube to ensure the support of the paper tube and facilitate demolding.

[0053] like Figure 3 As shown:

[0054] The impregnation plate 108 is slidably connected inside the impregnation tank 103, and a first electric push rod is fixed between the impregnation plate 108 and the impregnation tank 103.

[0055] When waste paper scraps fall onto the filter belt 105, the first electric push rod operates, thereby pushing the impregnation plate 108 upward, which in turn pushes the glue liquid above the impregnation plate 108 upward, so that the glue liquid comes into contact with the waste paper scraps, thereby completing the impregnation of the waste paper scraps. When conveying the waste paperboard outward, the first electric push rod falls back and drives the impregnation plate 108 downward, so that the liquid level of the glue liquid drops below the filter belt 105, thereby facilitating the squeezing out of excess glue liquid from the waste paper scraps.

[0056] like Figure 1 and Figure 8 As shown:

[0057] The receiving hopper 301 is fixedly connected to the bottom of the forming plate 201, the transition plate 302 is fixedly connected to the bottom side of the receiving hopper 301, and the two distributing plates 303 are rotatably connected to the two sides of the transition plate 302 respectively. A fourth rotary motor is provided between each distributing plate 303 and the transition plate 302, and multiple ejector pins 304 are fixedly connected to each distributing plate 303.

[0058] The processed paper tubes fall downwards, and the receiving hopper 301 catches them and slides them onto the transition plate 302 in a single row. At the same time, it drives two fourth rotary motors to work, thereby driving two distribution discs 303 to rotate. This causes the ejector pins 304 on the distribution discs 303 to move and contact the paper tubes. When the two distribution discs 303 rotate, the ejector pins 304 on them insert into the paper tubes, thus propelling the paper tubes into the next processing step. The ejector pins 304 on the distribution discs 303 are evenly distributed at fixed intervals, so that the paper tubes are conveyed at fixed intervals during the conveying process. This ensures that the paper tubes are distributed at fixed intervals between the two facing sheets, thereby ensuring that the pressure is evenly distributed when the corrugated cardboard is subjected to pressure, thus improving the pressure-bearing capacity of the corrugated cardboard.

[0059] like Figure 1 and Figure 9 As shown:

[0060] The forming plate 401 is fixed to the transition plate 302, the two slide plates 404 are fixed to the forming plate 401, and the two sliders 403 are slidably connected in the two slide plates 404 respectively. A second electric push rod is provided between each slider 403 and the corresponding slide plate 404, and a pressure roller 402 is rotatably connected between the two sliders 403.

[0061] A layer of facing paper passes through the gap between the forming plate 401 and the transition plate 302, and through the upper surface of the forming plate 401, thus serving as the lower surface of the corrugated cardboard. Another layer of facing paper passes under the pressure roller 402 and contacts the pressure roller 402. The paper tube is placed between the two layers of facing paper, and the second electric push rod is driven to work, so that the two second electric push rods push the two sliders 403 downward, thereby driving the pressure roller 402 downward, which in turn causes the pressure roller 402 to move the upper layer of facing paper downward, so that the facing paper covers the upper side of the paper tube. The outer wall of the paper tube still has glue residue, and then the pressure roller 402 applies pressure to the two layers of facing paper and the paper tube, so that the two layers of facing paper and the paper tube are bonded together, completing the processing of the corrugated cardboard.

[0062] like Figure 10 As shown:

[0063] Two rotating frames 406 are fixedly connected to both sides of the forming plate 401, and the trimming shaft 405 is rotatably connected between the two rotating frames 406. Two cutting blades 407 are slidably connected on the trimming shaft 405, and a scale is engraved on the trimming shaft 405.

[0064] According to the size requirements of the corrugated cardboard, push the two cutters 407 to slide on the trimming shaft 405 and slide to the appropriate position according to the scale. When the corrugated cardboard passes under the trimming shaft 405, the two cutters 407 cut the two sides of the corrugated cardboard to obtain the ideal size of the corrugated cardboard, and then process it into a corrugated box.
