Description

Technical Field

[0001] This invention relates to the field of cardboard processing technology, and more specifically, to a folding machine. Background Technology

[0002] In the production of high-end gift boxes, electronic product packaging boxes, luxury goods packaging and other paper products, a high-end packaging process is often used, which is made of cardboard and fine paper. In order to achieve a rounded visual effect and a comfortable feel, the corners of such packaging boxes are often designed to be rounded. Therefore, in the processing, large sheets of paper need to be precisely folded and wrapped around the pre-cut rounded corners.

[0003] Existing equipment has great difficulty in handling rounded corners, often resulting in failed folding and defective products. Manual folding is inefficient and costly. Summary of the Invention

[0004] In summary, to overcome the shortcomings of the prior art, the present invention provides a folding machine with rounded corner folding function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a folding machine, including a frame, a feeding mechanism, a conveying mechanism, and a side edge mechanism, and further including a rounding edge mechanism. The rounding edge mechanism includes a plurality of rounding edge components, which are arranged around a cardboard. Each rounding edge component includes a push block and a first driving member. The first driving member controls the push block to reciprocate in the direction of the cardboard, and the conveying mechanism moves the position of the cardboard on the frame.

[0006] Furthermore, the rounded edge assembly also includes a bottom block located below the push block.

[0007] Furthermore, the bottom block and the push block are linked and the bottom block is limited.

[0008] Furthermore, the rounded edge assembly also includes an elastic element that applies a force toward the cardboard to the base block.

[0009] Furthermore, the bottom block is provided with a quick-release block, the push block is provided through the quick-release block, and the quick-release block is provided with a slot that is adapted to the bottom block.

[0010] Furthermore, the rounded edge assembly also includes a plug rod, the push block has a strip-shaped hole, and the plug rod passes through the quick-release block and is inserted into the strip-shaped hole.

[0011] Furthermore, the rounded edge assembly also includes a base plate located below the side of the push block facing the cardboard, with the top surface of the base plate located between the top and bottom surfaces of the base block.

[0012] Furthermore, the rounded edge assembly also includes a second driving member, which drives the base plate to reciprocate in the direction of the push block.

[0013] Furthermore, the conveying mechanism is a suction cup type robotic arm, and the side mechanism includes a side pressure plate and a fourth driving member. Several side pressure plates are provided, and the fourth driving member drives several side pressure plates to move toward the cardboard.

[0014] Furthermore, the side mechanism also includes a support plate and a fifth driving member, the fifth driving member driving the support plate to reciprocate at the bottom of the side pressure plate toward the side pressure plate.

[0015] The beneficial effects of this invention are as follows: The cardboard to be processed is conveyed from a conveyor belt to the feeding position of the folding machine, and then conveyed by the feeding mechanism to the rounding edge mechanism. The cardboard is placed by the feeding mechanism at the processing position surrounded by several rounding edge components. When it is placed down, the face paper at the edge of the cardboard is first pressed down by the push block and then bent to an upward angle. After it is completely placed down, the cardboard will be under the push block. At this time, the first drive component will operate, driving the push block to move towards the cardboard. This will bend the face paper at the raised rounded corner towards the cardboard to the degree of adhering to the cardboard. In this way, the face paper at the rounded corner can be successfully folded and adhered. Next, the cardboard will be conveyed by the conveying mechanism to the side edge mechanism for regular edge folding of the face paper on the side of the cardboard. The whole process does not require manual operation and is more efficient. Attached Figure Description

[0027] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0028] Referring to the accompanying drawings, the present invention provides the following technical solution: a folding machine, including a frame 1, a feeding mechanism 2, a conveying mechanism 3, and a side edge mechanism 4, and further including a rounding edge mechanism 5. The rounding edge mechanism 5 includes a plurality of rounding edge components 51, which are arranged around the cardboard. Each rounding edge component 51 includes a push block 511 and a first driving member 512. The first driving member 512 controls the push block 511 to reciprocate in the direction of the cardboard. The conveying mechanism 3 moves the position of the cardboard on the frame 1. The first driving member 512 can be a cylinder or an electric telescopic mechanism, etc. The second driving member 518 and the fifth driving member 44 are similar.

[0029] With this setup, the cardboard to be processed is conveyed from the conveyor belt to the feeding position of the folding machine, and then conveyed by the feeding mechanism 2 to the rounding mechanism 5. The cardboard is placed by the feeding mechanism 2 at the processing position surrounded by several rounding components 51. When it is placed down, the face paper at the edge of the cardboard will first press down the push block 511 and then be bent to an upward angle. After it is completely placed down, the cardboard will be located below the push block 511. At this time, the first driving component 512 will operate, driving the push block 511 to move towards the cardboard. This will bend the face paper at the raised rounded corner towards the cardboard to the degree of adhering to the cardboard. In this way, the face paper at the rounded corner can be successfully folded and adhered. Next, the cardboard will be conveyed by the conveying mechanism 3 to the side folding mechanism 4 for regular edge folding of the face paper on the side of the cardboard. The whole process does not require manual operation and is more efficient.

[0030] In a preferred embodiment, the rounded edge component 51 further includes a bottom block 513, which is located below the push block 511.

[0031] With this configuration, the bottom block 513 ensures that the face paper at the bottom of the cardboard also receives the bending effect, resulting in a better bending effect. Furthermore, the bottom block 513 will not insert itself above the cardboard and will not damage the edges or corners of the cardboard.

[0032] In this preferred embodiment, the side of the bottom block 513 facing the cardboard is an arc surface.

[0033] With this setting, the curved surface can be set to the same curved shape as the corner of the cardboard, resulting in a better folding effect. The push block 511 can also be set to a curved surface for a better corner folding effect.

[0034] In this preferred embodiment, the bottom block 513 and the push block 511 are linked together, and the bottom block 513 is limited.

[0035] With this setup, when the push block 511 is moved toward the cardboard, the bottom block 513 will also be moved along with it. However, the bottom block 513 is designed to stop at the edge of the cardboard and will not continue to move and damage the cardboard, resulting in a better folding effect.

[0036] In a preferred embodiment, the rounded edge assembly 51 further includes an elastic element 514, which applies a force toward the cardboard to the bottom block 513.

[0037] With this configuration, the pusher block 511 only needs to be linked with the bottom block 513 during the retraction stroke, while the push-out process is implemented by the elastic element 514, ensuring that the bottom block 513 will not be pushed onto the cardboard.

[0038] In a preferred embodiment, the rounded edge component 51 further includes a mounting block 515, and the push block 511 is disposed through the mounting block 515.

[0039] With this configuration, the push block 511 can extend and retract within the mounting block 515, resulting in greater stability.

[0040] In this preferred embodiment, the elastic element 514 is a spring, and the mounting block 515 has a spring groove 5151 adapted to the elastic element 514 at one end facing the bottom block 513.

[0041] With this configuration, the spring will be placed in the spring groove 5151 and press against the bottom block 513, thus applying a force toward the cardboard. The structure is simple, and two springs can be provided, one on each side of the push block 511.

[0042] In this preferred embodiment, the bottom block 513 is provided with a quick-release block 5131, the push block 511 is provided through the quick-release block 5131, and the quick-release block 5131 is provided with a slot 51311 adapted to the bottom block 513.

[0043] With this design, when different rounded corner cardboard is replaced, the bottom block 513 inside the slot 51311 can be pulled out and replaced with a bottom block 513 that is compatible with different rounded corners. This makes disassembly and assembly convenient. In addition, the quick-release block 5131 increases the volume of the bottom block 513, making it easier for the spring to hold it in place. A bolt can also be set on the quick-release block 5131 to hold the bottom block 513 in place for stability.

[0044] In a preferred embodiment, the rounded edge assembly 51 further includes a rod 516, the push block 511 is provided with a strip hole 5111, and the rod 516 passes through the quick-release block 5131 and is inserted into the strip hole 5111.

[0045] With this configuration, after the insertion rod 516 passes through the quick-release block 5131 and is inserted into the slot 5111, it will retract along with the quick-release block 5131 and the bottom block 513 when the push rod retracts. When the push block 511 is pushed out, the insertion rod 516 will move in the slot 5111 and will not move together. The quick-release block 5131 will only be pushed by the spring.

[0046] The above settings are not limited. If the quick-release block 5131 is not set, the insert 516 can be changed to a through-bottom block 513.

[0047] In this preferred embodiment, the side of the quick-release block 5131 facing the cardboard is V-shaped.

[0048] With this design, the V-shape makes it easier to expose the ends of the push block 511 and the bottom block 513, and the two side angles of the V-shape can be adapted to the corners of the cardboard. This can provide a positioning effect on the edges of the face paper and the cardboard, making the cardboard more stable after it is placed down. The V-shape can also lift up the face paper on the side of the cardboard, so that the face paper at the rounded corner will not tear during the folding process.

[0049] The above settings are not limited. The included angle of the V-shape can also be set to an arc shape, or several baffles can be set independently to position the paper and cardboard instead of a V-shape.

[0050] In this preferred embodiment, the top edge of the quick-release block 5131 facing the cardboard is chamfered.

[0051] With this setup, the tissue paper will first touch the slanted chamfer before touching the vertical push block 511 and bottom block 513, resulting in a smoother bend and a better effect.

[0052] In a preferred embodiment, the first driving member 512 is provided with a sliding groove 5121, and the quick-release block 5131 is provided with a sliding protrusion 51312 that is adapted to the sliding groove 5121.

[0053] With this configuration, the quick-release block 5131 will slide within the sliding groove 5121 by relying on the sliding protrusion 51312, making the movement of the quick-release block 5131 more stable as it is pushed by the spring.

[0054] The above settings are not limited; the sliding groove 5121 and the sliding protrusion 51312 can be set in reverse.

[0055] In a preferred embodiment, the rounded edge assembly 51 further includes a base plate 517, which is located below the side of the push block 511 facing the cardboard, and the top surface of the base plate 517 is located between the top and bottom surfaces of the base block 513.

[0056] With this setup, the cardboard can be supported by the base plate 517, and the bottom block 513, after being pushed by the spring, will eventually hit the side of the base plate 517 and then stop. This way, it can stop at the edge of the cardboard and not continue, ensuring that the cardboard will not be damaged. The structure is simple, and the corners of the base plate 517 can also be set to the same angle as the corners of the cardboard.

[0057] In a preferred embodiment, the rounded edge assembly 51 further includes a second driving member 518, which drives the base plate 517 to reciprocate toward the push block 511.

[0058] With this setup, when bending the corner of the face paper, the push block 511 is finally inserted above the cardboard. At this time, the second drive unit 518 will operate to lift the bottom plate 517. In this way, the push block 511 and the bottom plate 517 will clamp the cardboard from the top and bottom sides, resulting in a better folding effect for the face paper.

[0059] In a preferred embodiment, the rounded edge mechanism 5 further includes a support rod 52, the top surface height of which is not lower than the lowest height of the top surface of the base plate 517.

[0060] With this configuration, the support rod 52 can provide support for the cardboard, resulting in a larger support area and greater stability.

[0061] In this preferred embodiment, the end of the push block 511 facing the base plate 517 has a chamfered edge on one side of the base block 513.

[0062] This setup prevents the tissue from getting stuck between the two parts, resulting in better performance.

[0063] In this preferred embodiment, the output shaft of the first driving member 512 is located at the end facing away from the cardboard, and the output shaft of the first driving member 512 is provided with a mounting plate 5122. The push block 511 is detachably connected to the mounting plate 5122.

[0064] With this configuration, when replacing the cardboard, the push block 511 can be removed from the mounting plate 5122, and the push block 511 can be pulled out directly for replacement. This makes disassembly and assembly convenient. The push block 511 can be connected using conventional methods such as bolts.

[0065] In a preferred embodiment, the push block 511 is provided with a quick-change head 5112, the quick-change head 5112 is detachably connected to the main body of the push block 511, and the mounting block 515 is provided with a quick-change port 5152 at the connection position between the quick-change head 5112 and the main body of the push block 511.

[0066] With this setup, quick-release head 5112 can be disassembled and assembled using parts such as pins or screws through quick-release port 5152. After being pulled out or unscrewed, quick-release head 5112 can be pulled out. The connection position between the two can be set with overlapping plates to facilitate the insertion of pins or screws.

[0067] In a preferred embodiment, the rounded edge mechanism 5 further includes an adjustment component 53, and the rounded edge component 51 further includes a mounting bracket 519. The adjustment component 53 includes a double-ended screw 531 and a third driving member 532. The third driving member 532 drives the double-ended screw 531 to rotate, and the double-ended screw 531 is threadedly connected to the mounting bracket 519.

[0068] With this setup, when the cardboard size changes, the third drive unit 532 can be driven. The third drive unit 532 can be a motor. After the third drive unit 532 drives the double-headed screw 531 to rotate, it will also change the position of the mounting bracket 519 in the two rounded edge components 51. By setting multiple third drive units 532 and double-headed screws 531, multiple rounded edge components 51 can be controlled to move together, thus adapting to cardboard of different sizes.

[0069] In a preferred embodiment, the frame 1 is provided with a sliding rail 11, and the mounting bracket 519 is slidably connected to the sliding rail 11.

[0070] With this configuration, the mounting bracket 519 slides more stably on the sliding rail 11.

[0071] In this preferred embodiment, the feeding mechanism 2 is a suction cup robotic arm.

[0072] With this setup, the suction cup robotic arm can press down from above to feed the material, thus achieving the effect of pressing the cardboard. In addition, the feeding mechanism 2 can be equipped with an image capture positioning camera, so the feeding position can be precisely controlled, resulting in a high yield.

[0073] In this preferred embodiment, the base plate 517 is provided with an adsorption port 5171.

[0074] With this configuration, the suction port 5171 can be equipped with a vacuum suction cup, so that the base plate 517 can have an adsorption effect on the cardboard, stabilizing its position and preventing it from shifting when the conveying mechanism 3 moves the cardboard.

[0075] The above settings are not limiting; suction ports 5171 can also be set in other locations that require stability, such as the side mechanism 4.

[0076] In this preferred embodiment, the conveying mechanism 3 is a suction cup type robot, and the side mechanism 4 includes a side pressure plate 41 and a fourth driving member 42. The side pressure plate 41 is provided in a plurality of manners, and the fourth driving member 42 drives the plurality of side pressure plates 41 to move toward the cardboard.

[0077] With this setup, the suction cup robot can place the cardboard from above into the processing position of the side mechanism 4. During the placement process, the side paper will press against the side pressure plate 41 and be initially bent to an upward position. At this time, the fourth drive unit 42 only needs to control the side pressure plate 41 to move towards the cardboard to push the paperboard into a state of adhering to the cardboard. The side pressure plate 41 is easy to move.

[0078] In this preferred embodiment, there are two side pressure plates 41, the fourth driving member 42 is a conveyor belt, and the side of the side pressure plate 41 is provided with a connecting block 411 that is fixedly connected to the fourth driving member 42. The connecting blocks 411 on the two side pressure plates 41 are respectively located on the upper and lower sides of the fourth driving member 42.

[0079] With this configuration, the connecting block 411 can be bolted to the conveyor belt or a synchronous belt can be used as the conveyor belt. Then, two matching blocks are used to clamp the conveyor belt as the connecting block 411. When the conveyor belt is rotated by the motor and other parts, it can move the connecting block 411 horizontally. After the connecting blocks 411 of the two side pressure plates 41 are set one above the other, they can move in opposite directions to achieve the effect of moving inward or outward together. The structure is simple. Two of the above-mentioned side mechanisms 4 can be set on the frame 1 to fold the long side and the short side respectively. Alternatively, one of the above-mentioned side mechanisms 4 can be set to handle the two sides. Then, a conventional side mechanism 4 is placed in another station. The mechanism that uses the side pressure plate 41 to move upward to push the face paper and then move horizontally to press towards the cardboard is responsible for the other two sides. After the long and short sides of the cardboard are all folded, an outlet flattening roller can be set at the outlet position to remove air bubbles and flatten the surface, making the product more compact and avoiding bulging.

[0080] In this preferred embodiment, the frame 1 is provided with a guide rail 12, and the connecting block 411 is slidably connected to the guide rail 12.

[0081] With this configuration, the connecting block 411 slides more stably on the guide rail 12.

[0082] In a preferred embodiment, the side mechanism 4 further includes a support plate 43 and a fifth driving member 44, wherein the fifth driving member 44 drives the support plate 43 to reciprocate toward the side pressure plate 41 from the bottom of the side pressure plate 41.

[0083] With this setup, the support plate 43 will be used as a processing platform. When the side pressure plate 41 moves onto the cardboard, the fifth drive member 44 will drive the support plate 43 to clamp the cardboard, thus ensuring that the face paper adheres completely to the cardboard and the folding effect is better.

[0084] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
