Description

Technical Field

[0001] This invention belongs to the field of corrugated cardboard box technology, and specifically relates to a processing method for corrugated cardboard packaging boxes. Background Technology

[0002] Corrugated cardboard boxes are made from corrugated cardboard through processes such as die-cutting, creasing, nailing, or gluing. Corrugated cardboard boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products. For over half a century, corrugated cardboard boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Corrugated cardboard boxes are considered environmentally friendly products, benefiting both the environment and the loading and unloading process; thus, they are ubiquitous in both production and daily life.

[0003] With the increasing popularity of corrugated cardboard boxes, there are also higher requirements for their production capacity. However, the following shortcomings still exist in the current production process of corrugated cardboard boxes:

[0004] 1. In the production of corrugated cardboard boxes, roller cutters are generally used to die-cut the corrugated cardboard. This method, through the cooperation of the transmission mechanism, feeds the corrugated cardboard one by one under the roller cutter as it rotates, thereby achieving the die-cutting of the corrugated cardboard by the roller cutter. However, this method of cutting one by one is inefficient and cannot meet the current production needs.

[0005] 2. During the production of corrugated cardboard boxes, the sharpness of the die-cutting blade decreases due to prolonged operation. This causes the cut corrugated cardboard to stick to the corrugated cardboard box after die-cutting. When folding and gluing the corrugated cardboard box, the sticky corrugated cardboard will affect the processing quality. Therefore, before folding and gluing, workers need to remove the cut corrugated cardboard. This not only affects the production efficiency of corrugated cardboard boxes, but also consumes a lot of manpower and increases labor costs. Summary of the Invention

[0006] To address the aforementioned problems, this invention proposes a processing method for corrugated cardboard boxes, which overcomes or at least partially solves these problems.

[0007] The processing method of this corrugated cardboard packaging box involves using corrugated cardboard packaging box processing equipment, which includes a circular saw and a clamp; the circular saw is configured with an adjustable position, and the clamp is capable of moving relative to the circular saw; the clamp is capable of stacking and fixing multiple corrugated cardboard packaging boxes.

[0038] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] Combination Figures 1 to 11 As shown, the corrugated cardboard packaging box processing equipment of this embodiment includes a circular saw 1 and a clamp 2. The circular saw 1 is mounted on the base 4 via a circular saw bracket 3 and is positioned in an adjustable manner. Specifically, in this embodiment, the position of the circular saw 1 can be adjusted in the horizontal direction. The clamp 2 can move vertically relative to the circular saw 1, and the clamp 2 can stack and fix multiple corrugated cardboard packaging boxes.

[0040] When processing corrugated cardboard boxes using the corrugated cardboard box processing equipment of this embodiment, multiple corrugated cardboard boxes can be stacked in the fixture at one time. That is, the fixture can simultaneously process and fix multiple corrugated cardboard boxes. After adjusting the position of the circular saw relative to the corrugated cardboard boxes in the fixture in the horizontal direction, by controlling the reciprocating movement of the fixture relative to the circular saw, the circular saw can complete the cutting operation of multiple corrugated cardboard boxes at one time, thereby greatly improving the processing efficiency of corrugated cardboard boxes.

[0041] Combination Figures 1 to 3 As shown, the corrugated cardboard packaging box processing equipment in this embodiment specifically includes two circular saws 1. The two circular saws 1 are spaced apart to serve as the first cutting station and the second cutting station, respectively. At the same time, the clamp 2 can drive the corrugated cardboard packaging box to rotate 180 degrees, and rotate it from the circular saw 1 at the first cutting station to above the other circular saw 1 at the second cutting station.

[0042] At this point, after the circular saw completes the cut on one side of the corrugated cardboard box at the first cutting station, the uncut side of the corrugated cardboard box can be flipped directly to the circular saw at the second cutting station by controlling the clamp to rotate 180 degrees. Then, by controlling the clamp to move vertically, the other side of the corrugated cardboard box can be cut quickly, improving the efficiency of cutting both sides of the corrugated cardboard box and the convenience of operation and control.

[0043] Combination Figures 4 to 6As shown, the corrugated cardboard packaging box processing equipment in this embodiment also includes a guide member 5, and a guide rod 6 is provided on the clamp 2. The guide member 5 includes a body 7 and a triangular block 8. A first inclined groove 9, a vertex groove 10 and a second inclined groove 11 are formed between the body 7 and the triangular block 8. One end of the guide rod 6 is fixedly connected to the clamp 2, and the other end is provided with a first guide pin 12 and a second guide pin 13. The first guide pin 12 and the second guide pin 13 can move along the bottom edge of the body 7 and the first inclined groove 9, the vertex groove 10 and the second inclined groove 11.

[0044] When the guide rod 6 moves relative to the guide member 5, the first guide pin 12 enters the first inclined groove 9, the apex groove 10 and the second inclined groove 11 from the bottom edge of the body 7 in sequence. At this time, the first guide pin 12 drives the entire guide rod 6 to rotate, so that the second guide pin 13 passes directly from the bottom edge of the body 7 around the triangular block 8 to the bottom edge on the other side. When the second guide pin 13 moves to the bottom edge of the body 7 and the first guide pin 12 also moves to the bottom edge of the body 7 along the second inclined groove 11, the guide rod 6 completes a 180-degree rotation. At the same time, the guide rod 6 also drives the clamp 2 to complete a 180-degree rotation.

[0045] In this way, by controlling the guide rod to move relative to the guide member, the fixture can be moved from the first cutting station to the second cutting station, and the fixture can drive the corrugated cardboard box to complete a 180-degree flip, improving the ease of operation and control.

[0046] Combination Figure 6 As shown, in this embodiment, the guide rod 6 and the clamp 2 are detachably connected by two connecting pins 14, so as to facilitate the connection and disassembly between the guide rod and the clamp, and to enable the use of different clamps and guide rods.

[0047] Combination Figures 1 to 4 As shown, the corrugated cardboard packaging box processing equipment in this embodiment also includes a clamping connecting plate 15. The clamping connecting plate 15 is sleeved on the outside of the guide member 5 and can reciprocate relative to the guide member 5. Two circular saws 1 are spaced apart along the circumference of the clamping connecting plate 15, and the guide rod 6 passes through the clamping connecting plate 15 radially and is rotatably connected to the clamping connecting plate 15.

[0048] At this point, by controlling the rotation of the clamp connecting plate relative to the guide member, the guide rod can be moved relative to the guide member, and the guide rod can be used to freely reciprocate and rotate the clamp.

[0049] Combination Figure 1 , Figure 4 and Figure 5As shown, the corrugated cardboard packaging box processing equipment in this embodiment also includes a drive shaft 16. The drive shaft 16 passes vertically through the guide member 5 and the clamp connecting plate 15, and is rotatably connected to the clamp connecting plate 15 via a flat key. By controlling the rotation of the drive shaft 16, the clamp connecting plate 15 can be driven to rotate relative to the guide member 5, thereby controlling the clamp 2 to flip and move.

[0050] Combination Figures 1 to 11 As shown, the corrugated cardboard packaging box processing equipment in this embodiment also includes a push rod 17, a pawl rod 18, a pawl 19, a ratchet 20, and a gear set composed of a first bevel gear 21 and a second bevel gear 22. The push rod 17 is vertically mounted on the base 4, and its extended end is connected to a guide member 5 to drive the guide member 5 to reciprocate vertically. The pawl rod 18 is vertically mounted on a mounting plate 23 fixedly connected to the base 4 and can reciprocate vertically relative to the mounting plate 23. The pawl 19 is unidirectionally rotatably connected to the pawl rod 18 via a torsion spring 24, and can reciprocate vertically with the pawl rod 18 and rotate relative to the pawl rod 18. The ratchet 20 is coaxially and fixedly connected to the first bevel gear 21, and the second bevel gear 22 is coaxially and fixedly connected to the drive shaft 16. The first bevel gear 21 and the second bevel gear 22 mesh with each other, so that the rotation of the ratchet 20 can drive the drive shaft 16 to rotate through the first bevel gear 21 and the second bevel gear 22. The pawl 19 can abut against the ratchet 20 to drive the ratchet 20 to rotate.

[0051] At this point, the push rod drives the guide to move upward, which in turn moves the clamping connecting plate upward until it contacts the pawl lever. Further upward movement pushes the pawl lever, causing the pawl to move upward and drive the ratchet to rotate. This, in turn, drives the drive shaft via the gear set, thus controlling the rotation of the clamping connecting plate. Afterward, the push rod is retracted and moved downward, releasing the push on the pawl lever. This allows the pawl to overcome the torsion spring and move downward relative to the ratchet, while the ratchet remains stationary. By repeatedly controlling the extension and retraction of the push rod, the pawl can drive the ratchet to rotate continuously in one direction, which in turn drives the clamping connecting plate to rotate in one direction via the drive shaft. This achieves control over the clamp's flipping and transfer between different workstations.

[0052] Furthermore, combined with Figures 7 to 10As shown, the corrugated cardboard packaging box processing equipment in this embodiment also includes a polygonal block 25, a sliding plate 26, and a sliding plate spring 27. The polygonal block 25 is located between the ratchet 20 and the first bevel gear 21 and is coaxially and fixedly connected to the ratchet 20. The sliding plate 26 is slidably connected to the mounting plate 23, and the two sliding plates 26 are respectively located on both sides of the polygonal block 25. The sliding plate spring 27 is connected to the sliding plate 26 to drive the sliding plate 26 to abut against the polygonal block 25. When the pawl 19 pushes the ratchet 20 to complete one rotation, the sliding plate 26 switches to abutment against two adjacent straight edges of the polygonal block 25, while the ratchet 20, through the drive shaft 16, drives the clamp 2 to transfer between two adjacent workstations.

[0053] At this point, by utilizing the contact formed between the sliding plate and the polygonal block, the sliding plate can restrict the free rotation of the polygonal block, thereby increasing the resistance to the ratchet's reverse rotation and allowing the ratchet to move freely back and forth with the ratchet bar. At the same time, it can also restrict the rotation of the drive shaft, thereby stabilizing the position of the clamp and improving the processing efficiency and quality of corrugated cardboard boxes.

[0054] Combination Figures 1 to 3 As shown, the corrugated cardboard packaging box processing equipment in this embodiment is also equipped with two suction rods 28. The suction rods 28 are mounted on the base 4 via suction brackets 29, and the two suction rods 28 are also spaced apart along the circumferential direction of the clamping connecting plate 15, and are both located downstream of the circular saw 1, for cleaning the sides of the corrugated cardboard packaging box after the cutting operation is completed.

[0055] In this way, by controlling the reciprocating extension and retraction of the push rod to drive the clamp connecting plate to rotate, the clamp can be driven to pass through two cutting stations in sequence to complete the cutting of both sides of the corrugated cardboard box. After that, it can move directly to the two dust suction rods and then rotate 180 degrees again, so that the two dust suction rods can complete the dust suction and cleaning of both sides of the corrugated cardboard box. This realizes the continuous operation of cutting and cleaning the corrugated cardboard box and improves the processing efficiency of the corrugated cardboard box.

[0056] Furthermore, in the corrugated cardboard packaging box processing equipment of this embodiment, the polygonal block 25 is a hexagonal block, the guide 5 is provided with six triangular blocks 8 and is evenly arranged along the circumference, the ratchet 20 is provided with six evenly distributed teeth, and the clamp connecting plate 15 is provided with six clamps 2 evenly distributed. At the same time, the corrugated cardboard packaging box processing equipment is provided with six corresponding workstations, namely the loading workstation, the first cutting workstation, the second cutting workstation, the first dust suction workstation, the second dust suction workstation, and the unloading workstation.

[0057] In this way, during one extension and retraction of the push rod, the ratchet can be driven by the pawl to complete a 60-degree rotation, which in turn drives the clamp connecting plate to complete a 60-degree rotation via the drive shaft. This allows the clamp to switch between two adjacent workstations, thereby enabling continuous processing of corrugated cardboard boxes and improving processing efficiency.

[0058] Combination Figure 3 As shown, the corrugated cardboard packaging box processing equipment in this embodiment is also equipped with an adjusting rod 30. The adjusting rod 30 is connected to the circular saw 1 and the dust suction rod 28 respectively, so as to adjust the position of the circular saw 1 and the dust suction rod 28 respectively, which facilitates the precise processing operation of corrugated cardboard packaging boxes of different shapes.

[0059] In addition, combined Figure 4 As shown, in the corrugated cardboard packaging box processing equipment of this embodiment, the clamp 2 adopts a square frame structure, and a push plate rod 32 connected to the push plate 31 is provided on each of the two adjacent side frames to clamp and fix multiple stacked corrugated cardboard packaging boxes, so as to ensure the processing quality of the corrugated cardboard packaging boxes.

[0060] Furthermore, in the corrugated cardboard packaging box processing equipment of this embodiment, two push rods 17 are provided. The two push rods 17 are arranged in parallel and fixed on the base 4, and are simultaneously connected to the guide member 5. In this way, not only can the stability of the vertical reciprocating drive control of the guide member be improved, but also the rotation of the guide member can be prevented, thereby further improving the processing quality and efficiency of the corrugated cardboard packaging box.

[0061] Combination Figures 1 to 11 As shown, the process of processing corrugated cardboard boxes using the corrugated cardboard box processing equipment of this embodiment includes:

[0062] Step S1, Preparation: Adjust and fix the position of the circular saw.

[0063] Specifically, when the corrugated cardboard packaging box processing equipment of this embodiment is needed to process corrugated cardboard packaging boxes, the adjusting rods 30 on the circular saw bracket 3 and the dust collection bracket 29 are started, which respectively drive the circular saw 1 and the dust collection rod 28 to move, so as to adjust the position of the circular saw 1 and the dust collection rod 28 according to the size of the corrugated cardboard packaging box to be processed. After the position adjustment of the circular saw 1 and the dust collection rod 28 is completed, the external dust collection equipment is connected to the dust collection rod 28, and the circular saw 1 is started to rotate, thus completing the preparation work.

[0064] Step S2, loading: Stack and fix multiple corrugated cardboard boxes to be processed in the fixture.

[0065] Specifically, multiple corrugated cardboard boxes to be processed are stacked sequentially in the clamp 2 of the loading station. The push plate lever 32 is controlled to move the push plate 31, thereby clamping and fixing the multiple corrugated cardboard boxes to complete the loading operation.

[0066] Step S3, moving the corrugated cardboard box to the working position: control the clamp to move relative to the circular saw, so that the clamp moves above the circular saw and moves the corrugated cardboard box to the working position.

[0067] Specifically, after the loading operation is completed, the two push rods 17 are extended to push the guide 5 and the clamp connecting plate 15 upward until the clamp connecting plate 15 moves to contact the pawl rod 18. The pawl rod 18 is then pushed to move the pawl 19 upward synchronously. The pawl 19 pushes the ratchet 20 to drive the polygonal block 25 to push the slide plate 26 to rotate against the force of the slide plate spring 27. Then, the first bevel gear 21 and the second bevel gear 22 drive the drive shaft 16 to rotate 60 degrees. The drive shaft 16 then drives the clamp connecting plate 15 to rotate 60 degrees relative to the guide 5, so that the clamp connecting plate 15 moves the clamp 2 from the loading station to the first cutting station. During the movement of the clamp 2 along with the clamp connecting plate 15, the clamp connecting plate 15 drives the guide rod 6 to move relative to the guide member 5, so that the first guide pin 12 enters the first inclined groove 9, the apex groove 10 and the second inclined groove 11 from the bottom of the body 7. When the first guide pin 12 enters the first inclined groove 9, it starts to drive the guide rod 6 to rotate, so that the second guide pin 13 goes directly from the bottom edge of the body 7 around the triangular block 8 to the bottom edge on the other side. When the second guide pin 13 moves to the bottom edge of the body 7, it drives the first guide pin 12 to move along the second inclined groove 11 to the bottom edge of the body 7, so that the guide rod 6 completes a 180-degree rotation, thereby driving the clamp 2 to complete a 180-degree rotation, transferring the clamp 2, which is located at the loading station and has a corrugated cardboard box fixed thereon, to the position above the circular saw 1 in the first cutting station.

[0068] Step S4, Cutting both sides of the corrugated cardboard box: Control the clamp to descend, use a circular saw to cut one side of the corrugated cardboard box in the clamp, control the clamp to rotate the corrugated cardboard box 180 degrees so that the other side of the corrugated cardboard box faces the circular saw, control the clamp to descend again, and use the circular saw to cut the other side of the corrugated cardboard box in the clamp.

[0069] Specifically, firstly, the two push rods 17 are retracted, causing the guide 5 and the clamping connecting plate 15 to move downwards, so that the clamp 2, carrying the corrugated cardboard box, gradually approaches the circular saw 1 at the first cutting station. The circular saw 1 then completes the cutting operation on the first side of the corrugated cardboard box. Next, the two push rods 17 are extended, causing the guide 5 and the clamping connecting plate 15 to move upwards again, pushing the pawl lever 18 and the pawl 19 to move upwards again, thus pushing the ratchet 20 to rotate 60 degrees again. This causes the drive shaft 16 to rotate the clamping connecting plate 15 60 degrees, thereby allowing the clamp 2 to switch positions and rotate 180 degrees, flipping the corrugated cardboard box, which has completed the first cutting operation, above the circular saw 1 at the second cutting station. Then, control the two push rods 17 to retract, causing the guide 5 and the clamp connecting plate 15 to move downwards, so that the clamp 2 carries the corrugated cardboard box closer to the circular saw 1 at the second cutting station. The circular saw 1 then completes the cutting operation on the other side of the corrugated cardboard box, thus completing the cutting operation on both sides of the corrugated cardboard box.

[0070] Step S5, Cleaning both sides of the corrugated cardboard box: After cutting both sides of the corrugated cardboard box, clean both sides of the corrugated cardboard box.

[0071] Specifically, after the second cut of the corrugated cardboard box is completed, the two push rods 17 are extended, causing the guide 5 and the clamp connecting plate 15 to move upward again. This pushes the pawl rod 18, along with the pawl 19, to move upward again, causing the ratchet 20 to rotate 60 degrees. This causes the drive shaft 16 to rotate the clamp connecting plate 15 60 degrees, allowing the clamp 2 to switch positions and rotate 180 degrees, flipping the corrugated cardboard box, which has completed the second cut, above the first cleaning station. Then, the two push rods 17 are retracted, causing the guide 5 and the clamp connecting plate 15 to move downward. This allows the clamp 2 to gradually approach the vacuum rod 28 at the first cleaning station with the corrugated cardboard box. As the vacuum rod 28 passes through the cut groove on one side of the corrugated cardboard box, the external vacuuming equipment sucks away the internal debris, completing the vacuuming and cleaning of that side. Next, the two push rods 17 are extended, causing the guide 5 and the clamp connecting plate 15 to move upward again, pushing the pawl lever 18 to move the pawl 19 upward again, so that the ratchet 20 rotates 60 degrees again, causing the drive shaft 16 to drive the clamp connecting plate 15 to rotate 60 degrees, thereby causing the clamp 2 to switch positions and rotate 180 degrees, flipping the corrugated cardboard box that has completed the first cleaning operation to above the vacuum rod 28 of the second cleaning position. Then, the two push rods 17 are retracted, causing the guide 5 and the clamp connecting plate 15 to move downward, so that the clamp 2, with the corrugated cardboard box, gradually approaches the vacuum rod 28 of the second cleaning position. When the vacuum rod 28 passes through the groove on the other side of the corrugated cardboard box, the external vacuuming equipment sucks away the internal debris, thus completing the cleaning operation on both sides of the corrugated cardboard box.

[0072] Step S6, Unloading: After cutting and cleaning both sides of the multiple corrugated cardboard boxes in the fixture, remove the multiple corrugated cardboard boxes from the fixture to complete the unloading.

[0073] Specifically, after cleaning both sides of the corrugated cardboard box, the two push rods 17 are extended, causing the guide 5 and the clamp connecting plate 15 to move upward again, pushing the pawl rod 18 to move the pawl 19 upward again, so as to push the ratchet 20 to rotate 60 degrees, causing the drive shaft 16 to drive the clamp connecting plate 15 to rotate 60 degrees, so that the clamp 2 can switch positions and rotate 180 degrees, flipping the corrugated cardboard box that has completed the second cleaning operation to the unloading position. Then, the two push rods 17 are retracted, causing the guide 5 and the clamp connecting plate 15 to move downward, and the push plate rod 32 is controlled to drive the push plate 31 to move, releasing the clamping and fixing of multiple corrugated cardboard boxes, taking out the processed corrugated cardboard boxes, and completing the unloading operation.

[0074] Step S7, Cyclic operation: Repeat steps S1 to S6 to continuously and automatically cut and clean the corrugated cardboard boxes.
