Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wood substitute carton processing, in particular to a wood substitute carton processing device and a wood substitute carton processing method. BACKGROUND

[0002] A wood substitute carton is a carton or paperboard produced using plant fibers or other raw materials that replace traditional wood. The wood substitute carton is made of renewable resources or recycled paper pulp as raw materials to reduce the demand for natural wood and help reduce the impact on the environment. At the same time, the wood substitute carton has higher pressure capacity than ordinary cartons, so it is widely used in heavy goods packaging and transportation fields and is gradually favored by more and more enterprises and consumers.

[0003] The existing wood substitute carton needs to be edge folded during processing. First, any two edges of a piece of wood substitute paperboard are cut with notches (as shown in Figure 11 ), to determine the edge folding position and subsequent corner folding operation. When edge folding the wood substitute paperboard, pressure needs to be applied to the edge folding position. The existing method is to directly use a rectangular plate to press down. Different sizes of pressing plates need to be replaced for different batches of wood substitute cartons of different sizes, which is tedious and time-consuming. In the existing processing process, when the wood substitute paperboard is moved to different work areas, a special moving device is needed, and the wood substitute paperboard needs to be clamped. After the edge folding operation is completed, the moving device needs to be used again to move the edge-folded wood substitute paperboard out of the workbench. The whole process is tedious and requires multiple different devices to alternate and work on the wood substitute paperboard. Moreover, many existing edge folding plates are vertical plate structures that directly extrude and fold the edge folding part, which can easily damage the contact part of the wood substitute paperboard and the edge folding plate, affecting the yield of the product.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Please see Figure 1 , Figure 2 and Figure 4A wood-substitute cardboard box processing device includes a workbench 1 for placing the wood-substitute cardboard boxes and a receiving plate 2 located above the workbench 1. The upper part of the receiving plate 2 is detachably connected to a robotic arm. A first electric telescopic rod 20 is rotatably connected through the center of the receiving plate 2. The fixed end of the first electric telescopic rod 20 is connected to a drive source. An expansion component 3 is provided at the fixed end of the first electric telescopic rod 20. The telescopic end of the first electric telescopic rod 20 is connected to a pressing and limiting mechanism 4. Four adjustment slots 21 are circumferentially opened at the bottom end of the receiving plate 2. A second electric telescopic rod 22 is slidably connected in each adjustment slot 21. A first spring 23 is fixedly connected between the fixed end of the second electric telescopic rod 22 and the side wall of the adjustment slot 21. The first spring 23 plays a buffering role during the movement of the second electric telescopic rod 22. A first folding mechanism 5 is provided at the telescopic ends of the front and rear second electric telescopic rods 22, and a second folding mechanism 6 is provided at the telescopic ends of the left and right second electric telescopic rods 22.

[0039] During operation, the robotic arm is moved to the top of the wood substitute carton to be processed until the pressing and limiting mechanism 4 adsorbs the upper surface of the wood substitute carton. The adsorbed wood substitute carton is then moved to the top of the workbench 1. The area of ​​the wood substitute carton to be processed is larger than the area of ​​the workbench 1. During this process, the first folding mechanism 5 and the second folding mechanism 6 are moved away from each other under the action of the expansion component 3. Under the action of the second electric telescopic rod 22, the first folding mechanism 5 and the second folding mechanism 6 are at the bottom position.

[0040] See Figure 4 and Figure 7 The expansion component 3 includes a plum blossom-shaped cam 31 fixedly connected to the fixed end of the first electric telescopic rod 20. A sliding groove 32 is provided on the side of the plum blossom-shaped cam 31. Four ejector rods 33 are slidably connected in the sliding groove 32. The other ends of the front and rear ejector rods 33 are slidably connected in the vertical grooves opened on the front and rear first connecting plates 52, respectively. The other ends of the other two ejector rods 33 are slidably connected in the limiting grooves opened on the left and right second connecting plates 63, respectively.

[0041] During operation, the drive source on the first electric telescopic rod 20 is activated. The drive source can be a motor. While driving the first electric telescopic rod 20 to rotate, it also drives the plum blossom-shaped cam 31 to rotate. One end of the four ejector rods 33 located in the sliding groove 32 is limited by the vertical groove and the limiting groove, respectively. The four ejector rods 33 move from the recess of the initial sliding groove 32 to the protrusion, pushing the first connecting plate 52 and the second connecting plate 63 on opposite sides to a state of being far apart.

[0042] See Figure 1 , Figure 8 and Figure 9The first folding mechanism 5 includes a limiting rod 51 fixedly connected to the telescopic end of the second electric telescopic rod 22. The bottom end of the limiting rod 51 is fixedly connected to a first connecting plate 52, and the bottom end of the first connecting plate 52 is fixedly connected to a first folding plate 53. The second folding mechanism 6 includes a transverse plate 61 fixedly connected to the telescopic end of the second electric telescopic rod 22. Rectangular holes 62 are provided on both the front and rear sides of the transverse plate 61. The left and right ends of the limiting rod 51 on the front side are slidably connected to the rectangular holes 62 on the front side of the two transverse plates 61, and the left and right ends of the limiting rod 51 on the rear side are slidably connected to the rectangular holes 62 on the rear side of the two transverse plates 61. The bottom end of the transverse plate 61 is fixedly connected to a second connecting plate 63, and the bottom end of the second connecting plate 63 is fixedly connected to a second folding plate 64. The bottom ends of the two second folding plates 64 are provided with folding corner components 7. The first folded edge plate 53 and the second folded edge plate 64 have the same shape. The length of the first folded edge plate 53 is shorter than the length of the second folded edge plate 64. The first folded edge plate 53 consists of two vertical parts at the top and bottom and a middle inclined part. The inclined parts of the two first folded edge plates 53 are arranged close to each other from top to bottom. The length of the upper vertical part of the first folded edge plate 53 is shorter than the length of the upper vertical part of the second folded edge plate 64. The height of the bottom of the first folded edge plate 53 is higher than the height of the bottom of the second folded edge plate 64.

[0043] During operation, when the cardboard box is moved onto the workbench 1, the bottom edges of the first folding plate 53 and the second folding plate 64 do not contact the side of the workbench 1 during placement. When performing the folding operation, the drive source on the first electric telescopic rod 20 is activated again, causing the plum blossom-shaped cam 31 to rotate until the four ejector rods 33 move from the protrusions of the sliding groove 32 to the recesses. During this process, the position of the limiting rod 51 relative to the horizontal plate 61 moves to accommodate the movement of the first connecting plate 52 and the second connecting plate 63. At this time, the uppermost vertical parts of the first folding plate 53 and the second folding plate 64 contact the side of the cardboard box to be processed. Then, the second electric telescopic rod 22 is activated simultaneously, pulling the first folding plate 53... The first folding plate 53 and the second folding plate 64 move upward. Since the upper end of the first folding plate 53 is shorter, the inclined part on the first folding plate 53 will first contact the side of the substitute wood carton, folding the front and rear sides of the substitute wood carton upward. Then the second electric telescopic rod 22 continues to move upward until the vertical part at the lower end of the first folding plate 53 is completely in contact with the folded edge of the substitute wood carton. The inclined part of the second folding plate 64 will begin to contact the side of the substitute wood carton, folding the left and right sides of the substitute wood carton upward until the lower end of the second folding plate 64 contacts the folded edge of the substitute wood carton. The second electric telescopic rod 22 stops moving upward. At this time, the folding corner assembly 7 is activated to bend the front and rear sides of the left and right sides of the substitute wood carton towards the front and rear sides of the substitute wood carton.

[0044] See Figure 1 , Figure 8 ,Figure 9 , Figure 10 and Figure 11 The angle-folding assembly 7 includes a connecting block 71 fixedly connected to the bottom end of the second folding plate 64. A placement groove 72 is provided in the middle of the connecting block 71. Two clearance grooves 73 are provided at the front and rear of the opposite ends of the two connecting blocks 71. The clearance grooves 73 are connected to the placement groove 72. A dual-axis motor 74 is fixedly installed in the middle of the placement groove 72. Rotating shafts 75 are connected to the front and rear ends of the dual-axis motor 74. A support ring is rotatably connected to the rotating shaft 75. The support ring is connected inside the placement groove 72 and serves to support the rotating shaft 75. A driving bevel gear 76 is fixedly connected to the other end of the rotating shaft 75. A pushing block 77 is slidably connected in the clearance groove 73. A threaded hole is provided on the side of the pushing block 77 near the placement groove 72. A threaded rod 78 is threadedly connected in the threaded hole. The other end of the threaded rod 78 is rotatably connected to the inner wall of the placement groove 72. A driven bevel gear 79 is fixedly connected to the threaded rod 78 and meshes with the driving bevel gear 76. Two push blocks 77 located on the same connecting block 71 are symmetrically arranged, and the ends of the two push blocks 77 that are away from the relief groove 73 on opposite sides are inclined.

[0045] When in operation, the dual-axis motor 74 is started, which drives the rotating shafts 75 on the front and rear sides to rotate. The driving bevel gear 76 will mesh with the driven bevel gear 79 on the threaded rod 78 to rotate, driving the threaded rod 78 to rotate. At the same time, the threaded rod 78 will drive the pushing block 77 to move away from the relief groove 73. The pushing block 77 will push the front and rear ends of the left and right sides of the substitute wood carton to bend towards the front and rear folding edges of the substitute wood carton.

[0046] See Figure 5 and Figure 6 The pressing and limiting mechanism 4 includes four right-angled pressure plates 41 arranged in a matrix. The right-angled pressure plates 41 are all connected to the synchronous adjustment component 43 through connecting rods 42. The right-angled pressure plates 41 have through holes, and adsorption components 44 are installed in the through holes. A rectangular rod 45 is fixedly connected to the upper end of the right-angled pressure plate 41 at a right angle.

[0047] During operation, the four right-angle pressure plates 41 simultaneously press down on the edges of the substitute wood carton that need to be folded, so as to facilitate the perpendicularity of the crease line when the first folding plate 53 and the second folding plate 64 fold the side of the substitute wood carton. The rectangular rod 45 on the right-angle pressure plate 41 provides support and fixation to the inside of the fold when the substitute wood carton is folded, so as to determine the position of the fold. The synchronous adjustment component 43 on the right-angle pressure plate 41 can adjust the position of the four right-angle pressure plates 41 synchronously to accommodate the pressing of the fold at the edge of the substitute wood carton of different sizes. When the synchronous adjustment component 43 is working, the adsorption component 44 does not perform adsorption operation on the substitute wood carton.

[0048] Continue reading Figure 5 andFigure 7 The synchronous adjustment component 43 includes a rectangular frame 431. The upper end of the rectangular frame 431 is rotatably connected to the telescopic end of the first electric telescopic rod 20. A rotating disk 432 is rotatably connected inside the cavity of the rectangular frame 431. A rotating motor 433 is disposed in the middle of the rotating disk 432 and is fixedly connected inside the cavity of the rectangular frame 431. Four arc-shaped grooves 434 are formed on the rotating disk 432 along its circumference. One end of the arc-shaped groove 434 is close to the center of the rotating disk 432, and the other end is close to the edge of the rotating disk 432. Four sets of [unclear] are fixedly connected inside the cavity of the rectangular frame 431. A rectangular limiting slide bar 435 is provided. Each set of rectangular limiting slide bars 435 consists of two symmetrically arranged rectangular limiting slide bars 435. A rectangular channel is formed between the two rectangular limiting slide bars 435. A rectangular through hole 436 is provided in the middle of the four sides of the rectangular frame 431. The rectangular through hole 436 and the rectangular through slot are positioned in a one-to-one correspondence. A moving rod 437 is slidably connected in the rectangular channel. A pushing rod 438 is fixedly connected to the upper end of the moving rod 437. The pushing rod 438 is slidably connected in the arc groove 434. A connecting rod 42 is fixedly connected to the side of the moving rod 437 near the rectangular through hole 436.

[0049] During operation, the rotating motor 433 is started, which drives the rotating disk 432 to rotate. As the rotating disk 432 rotates, it will drive multiple push rods 438 to move in the arc groove 434. The moving rod 437 connected to the push rod 438 moves in the rectangular channel and moves to the outside of the rectangular through hole 436 until it drives the connecting rod 42 to push the right angle pressure plate 41 to move outward. Adjust it to a suitable position according to the size of the folding edge required for the wood substitute carton until the right angle edge of the right angle pressure plate 41 coincides with the folding edge line.

[0050] The adsorption assembly 44 includes a suction cup 441 disposed in a through hole. The upper end of the suction cup 441 is connected to a telescopic hose 442. Multiple telescopic hoses 442 pass through the receiving plate 2 and are connected to a vacuum pump 443. The vacuum pump 443 is fixedly connected to the upper end of the receiving plate 2.

[0051] When the adsorption component 44 is working, when the right-angle pressure plate 41 is attached to the upper end of the substitute wood carton, the bottom end of the suction cup 441 is pressed down to the upper end of the substitute wood carton. The vacuum pump 443 is started to make the suction cup 441 have a stronger adsorption force on the substitute wood carton. This is to move the substitute wood carton to different work areas, and to make the right-angle pressure plate 41 press down more stably when the substitute wood carton is folded.

[0052] See Figure 9It also includes a pressure holding mechanism 8. The opposite surfaces of the two first folded edge plates 53 are provided with a pressure holding mechanism 8. The opposite surfaces of the first folded edge plates 53 are provided with a U-shaped groove 81. A pressure holding plate 82 is fixedly connected in the U-shaped groove 81 by a spring. The upper ends of the two pressure holding plates 82 are inclined close to each other from top to bottom. The opposite surfaces of the two second folded edge plates 64 are also provided with a pressure holding mechanism 8.

[0053] The pressure holding mechanism 8 further presses the folded edge of the wood substitute carton. Under the action of the spring, the pressure holding plate 82 protrudes out of the outer side of the U-shaped groove 81. When the pressure holding plate 82 is squeezed by the side of the worktable 1, the side of the pressure holding plate 82 and the side of the first folding plate 53 are on the same plane. After the first folding plate 53 is in this position, the pressure holding plate 82 can press the front and rear sides of the wood substitute cardboard close together, so that the folded edge of the wood substitute carton and the inner angle of the bottom of the wood substitute carton are less than 90 degrees. When the pressure holding plate 82 presses the left and right sides of the wood substitute cardboard, the left and right folded edges of the wood substitute carton tend to approach each other due to the action of the rectangular rod 45. However, the folded edge of the wood substitute carton and the inner angle of the bottom of the wood substitute carton are equal to 90 degrees, and it does not affect the normal operation of the corner folding assembly 7.

[0054] In addition, the present invention also provides a method for processing wood substitute cardboard boxes, specifically including the following steps:

[0055] Step 1: Activate the synchronous adjustment component 43 to adjust the size of the same batch of wood substitute cartons and fix the position of the right angle pressure plate 41.

[0056] Step 2: Activate the expansion component 3 to bring the uppermost vertical part of the first folding plate 53 and the second folding plate 64 into contact with the side of the wood substitute carton to be processed.

[0057] Step 3: Move the robotic arm to the top of the wood substitute carton to be processed until the pressing limit mechanism 4 contacts the top surface of the wood substitute carton, and start the adsorption component 44 to adsorb the top surface of the wood substitute carton, and move the adsorbed wood substitute carton to the top of the workbench 1.

[0058] Step 4: Move the first folding mechanism 5 and the second folding mechanism 6 upwards to fold the front and back sides of the wood substitute carton first, and then fold the left and right sides of the wood substitute carton.

[0059] Step 5: After the wood substitute carton is folded, the pressure holding mechanism 8 applies further pressure to the folded edge of the wood substitute carton to prolong the durability of the crease.

[0060] Step 6: Activate the corner folding component 7 again to fold the corners of the left and right sides of the wood substitute carton, thereby completing the edge folding process of the wood substitute carton. Then, move the edge-folded wood substitute carton directly to the next process.
