Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a profile packaging machine and a profile packaging method. Background Art

[0002] When packaging strip materials such as profiles, it is necessary to wrap the wrapping paper around the outside of the material for packaging. In actual production, the size of the wrapping paper used is usually fixed, while the overall volume of the material changes according to different production needs. When the overall material is small, the width of the wrapping paper is too large relative to the material to be packaged. If the wrapping paper is directly wrapped around the outside of the material, multiple folds will be directly pressed out, affecting the packaging effect. Therefore, a packaging machine that can adjust the width of the wrapping paper according to different usage needs is urgently needed. Summary of the invention

[0003] The object of the present invention is to provide a profile packaging machine and a profile packaging method to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A profile packaging machine comprises a frame, on which are arranged: a conveying device; a paper placing device, located at the conveying start end of the conveying device, the paper placing device is provided with a paper guide roller and a dotted line knife, a paper passing gap is formed between the dotted line knife and the outer side of the paper guide roller, the paper placing device is used to place the packaging paper through the paper passing gap, and the dotted line knife draws a paper folding dotted line on the packaging paper; a paper pulling device, having a paper pulling gripper that can move back and forth along the conveying direction of the conveying device, the paper pulling device is used to pull the packaging paper released from the paper passing gap to the paper passing gap, and the paper pulling device is used to pull the packaging paper released from the paper passing gap to the paper passing gap. On the conveying device; a positioning clamp is located on one side perpendicular to the conveying direction of the conveying device, the positioning clamp reciprocates along the conveying direction perpendicular to the conveying device, and the positioning clamp is used to adjust the position of the packaging paper released to the conveying device along the conveying direction perpendicular to the conveying device; a support plate is located on the other side perpendicular to the conveying direction of the conveying device, and a folding device is provided on the support plate, the folding device has a rotatable folding plate, and the folding plate is used to fold the side of the packaging paper away from the positioning clamp toward the direction of the positioning clamp.

[0006] The technical solution has at least the following beneficial effects: the size of the packaging paper can be adjusted when the packaging paper is loaded. Specifically, the paper feeding device is used to feed the packaging paper to the conveying device. Before feeding, the packaging paper passes through the paper passing gap formed by the paper guide roller and the dotted line knife, and the dotted line knife forms a folded paper dotted line on the packaging paper. After feeding, the packaging paper is clamped by the paper pulling clamp and pulled along the length direction of the conveying device, so that the packaging paper is spread on the conveying device after feeding, and then the positioning clamp clamps one side of the packaging paper to drive the packaging paper to move in a conveying direction perpendicular to the conveying device, so that the folded paper dotted line formed on the packaging paper is close to the folding plate. Then the folding plate rotates toward the direction of the positioning clamp to fold the wrapping paper 180 degrees along the imaginary line of the folded paper. In this way, the width of the wrapping paper is shortened by folding the edges of the wrapping paper, thereby adjusting the size of the wrapping paper. Then, the material to be packaged is placed on the wrapping paper for packaging. At this time, the phenomenon of wrinkles when the wrapping paper is wrapped on the material can be effectively reduced. The wrapping paper with adjusted size is more compact and beautiful when packaging the material, thereby improving the packaging quality.

[0007] As a further improvement of the above technical solution, the paper placing device includes a first lifting drive member and a lifting seat, the first lifting drive member is arranged on the frame, the lifting seat is arranged on the first lifting drive member, the first lifting drive member can drive the lifting seat downward to approach or upward to move away from the paper guide roller, and the dotted line knife is rotatably connected to the lifting seat. Before the packaging paper needs to be fed into the paper feeding gap, the first lifting drive member can drive the lifting seat upward to move away from the paper guide roller, at which time the paper feeding gap increases, and the packaging paper can be conveniently fed in. When the packaging paper needs to be fed outward, the first lifting drive member drives the lifting seat downward to move close to the paper guide roller, and the paper feeding gap decreases. At this time, the dotted line knife presses the packaging paper against the outside of the paper guide roller. As the packaging paper moves, the dotted line knife is driven to rotate and forms a paper folding dotted line on the packaging paper.

[0008] As a further improvement of the above technical solution, the paper placing device also includes an adjusting screw rod disposed between the frame and the first lifting drive member, and the adjusting screw rod can drive the first lifting drive member to move along a conveying direction perpendicular to the conveying device. According to the required size of the packaging paper, the position of the dotted line knife can be adjusted along the width direction of the conveying device by adjusting the screw rod, so that an origami dotted line can be formed at the corresponding position of the packaging paper, and different origami widths can be formed when the packaging paper is folded, so as to better adapt to different usage requirements.

[0009] As a further improvement of the above technical solution, the paper placing device includes a paper guide shell, a first glue gun and a second glue gun. The paper guide shell is located between the paper guide roller and the conveying device. The paper guide shell is surrounded by a guide channel that passes through the conveying direction of the conveying device. The first glue gun and the second glue gun are arranged above the paper guide shell at intervals perpendicular to the conveying direction of the conveying device. A first avoidance hole is provided on the top side of the paper guide shell facing the first glue gun, and a second avoidance hole is provided on the top side of the paper guide shell facing the second glue gun. After the wrapping paper passes through the paper gap, it is sent out from the guide channel formed by the paper guide shell. By guiding the wrapping paper through the guide channel, the wrapping paper can be more accurately directed and sent out, so that the paper pulling clamp can stably clamp the sent wrapping paper. In addition, during the wrapping paper feeding process, the first glue gun and the second glue gun can discharge glue from the top of the paper guide shell downward, and the glue passes through the first avoidance hole and the second avoidance hole respectively and then drips onto the wrapping paper. The glue at one point can be folded and bonded to the wrapping paper using a folding plate, and the glue at another point can be bonded and fixed after the wrapping paper completes the packaging of the material.

[0010] As a further improvement of the above technical solution, the paper pulling device includes a paper pulling translation seat, which can move back and forth on the frame along the length direction of the conveying device, and the paper pulling clamp includes a lower clamp and an upper clamp arranged on the paper pulling translation seat, and the upper clamp can move downward toward or upward away from the lower clamp on the paper pulling translation seat. Before the packaging paper is pulled and conveyed, the upper clamp is in a state away from the lower clamp, and when the packaging paper is released outward, the paper pulling translation seat moves horizontally toward the paper placing device, so that the packaging paper enters between the upper clamp and the lower clamp, and then the upper clamp moves downward toward the lower clamp to clamp the packaging paper, and the paper pulling translation seat moves in a direction away from the paper placing device, so that the released packaging paper is flatly laid on the conveying device.

[0011] As a further improvement of the above technical solution, the positioning clamp includes a positioning frame and a positioning pressure block. The positioning frame can move along a conveying direction perpendicular to the conveying device. The positioning frame forms a limited concave angle at the position opposite to the conveying device. The positioning pressure block is arranged on the positioning frame. The positioning pressure block can move up and down in the limited concave angle. When the wrapping paper is laid on the conveying device, one side of the wrapping paper is located in the limited concave angle. The limited concave angle pre-positions one side of the wrapping paper. Then the positioning pressure block moves downward to press the wrapping paper tightly and position it in the limited concave angle. At this time, the positioning frame can move along a conveying direction perpendicular to the conveying device to adjust the position of the folded paper virtual line. In this way, the position of the wrapping paper along the width direction of the conveying device can be accurately adjusted.

[0012] As a further improvement of the above technical solution, the folding device includes a paper-folding frame, a guide shaft and a tension spring. The side of the paper-folding frame close to the conveying device is rotatably connected to the frame. A hole is provided on the support plate opposite to the paper-folding frame. The guide shaft is connected to the frame and is located between the paper-folding frame and the conveying device. The folding plate is a belt-like structure. One end of the folding plate is connected to the side of the paper-folding frame away from the conveying device, and the other end of the folding plate extends toward the direction close to the conveying device and downwardly bypasses the guide shaft. The tension spring is connected between the bottom end of the folding plate and the frame. The paper-folding frame can be rotated in the direction close to the conveying device to protrude from the hole or rotated in the direction away from the conveying device to be retracted into the hole. When the wrapping paper is laid on the conveying device, the folding plate is in a state of being retracted into the hole, and the folding plate itself will not interfere with the movement of the wrapping paper along the width direction of the conveying device. When the wrapping paper needs to be folded along the folding imaginary line, the folding frame rotates in the direction close to the conveying device, and the folding plate rotates to protrude out of the hole, and drives the wrapping paper to be folded along the folding imaginary line. The folding plate is a belt-shaped structure, and the tension spring can keep the folding plate straightened. When the folding plate rotates to abut against the support plate, after the folding plate abuts against the edge of the hole of the support plate, it can further rotate, so that the folding plate can press the wrapping paper more tightly against the support plate, complete the folding of the wrapping paper, and improve the folding effect of the wrapping paper. After completion, the folding frame moves in the direction away from the conveying device and is re-retracted into the hole to avoid interfering with the next wrapping paper loading.

[0013] As a further improvement of the above technical solution, a material clamping and folding paper device and a material pressing device are also provided on the frame, the material clamping and folding paper device includes a first material clamping plate, a second material clamping plate and a first folding paper board and a second folding paper board located on both sides of the conveying device, the first material clamping plate and the second material clamping plate can approach or move away from each other, the first folding paper board is located above the first material clamping plate, and the second folding paper board is located above the second material clamping plate, when the conveying device moves downward, the first folding paper board and the second folding paper board can approach or move away from each other, the material pressing device is located above the conveying device, and the material pressing device has a pressure head that can move up and down.

[0014] As a further improvement of the above technical solution, a first brush is provided on one side of the first clamping plate and the second clamping plate facing each other, and a second brush is provided on the bottom side of the first folding paper board and the bottom side of the second folding paper board.

[0016] Get the size of wrapping paper required for packaging profiles;

[0017] The position of the dotted line knife is adjusted according to the size of the packaging paper, and the packaging paper is passed through the paper feeding gap so that a paper folding dotted line is formed on the packaging paper, and the packaging paper is pulled out to the conveying device by the paper pulling clamp;

[0018] The positioning clamp grips one side of the packaging paper and drives the packaging paper to move, so that the paper folding imaginary line on the packaging paper approaches the folding plate, and the folding plate folds the packaging paper along the paper folding imaginary line;

[0019] The profile is fed onto the packaging paper, and the packaging paper is folded along the profile shape for packaging.

[0020] The technical solution has at least the following beneficial effects: when using the above-mentioned profile packaging machine, the position of the dotted line knife can be adjusted according to the different sizes of packaging paper required for packaging profiles, so that when the packaging paper is sent out through the dotted line knife, an origami dotted line is formed at the corresponding position, and after the packaging paper is released, the packaging paper is clamped by the paper pulling clamp and pulled along the length direction of the conveying device, so that the packaging paper is spread on the conveying device after being released, and then the positioning clamp clamps one side of the packaging paper to drive the packaging paper to move along the conveying direction perpendicular to the conveying device, so that the origami dotted line formed on the packaging paper approaches the folding plate, and then the folding plate rotates toward the positioning clamp to fold the packaging paper 180 degrees along the position of the origami dotted line. In this way, according to the size of different materials, the width of the packaging paper can be shortened by folding the edges of the packaging paper, thereby adjusting the size of the packaging paper, and then the material to be packaged is placed on the packaging paper for packaging. At this time, the phenomenon that wrinkles are easily formed when the packaging paper is wrapped on the material can be effectively reduced. The packaging paper with adjusted size is more compact and beautiful when packaging the material, thereby improving the quality of profile packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Reference Figure 1 , Fig.10 , Fig.11 and Fig.12A profile packaging machine comprises a frame 100, on which a conveying device 200, a paper placing device 300, a paper pulling device 400, a position adjusting clamp 500 and a support plate 110 are arranged, wherein the paper placing device 300 is located at the conveying start end of the conveying device 200, the paper placing device 300 is provided with a paper guide roller 310 and a dotted line knife 320, a paper passing gap is formed between the dotted line knife 320 and the outer side of the paper guide roller 310, the paper placing device 300 is used to release the packaging paper through the paper passing gap, and the dotted line knife 320 draws a paper folding dotted line on the packaging paper; the paper pulling device 400 has a paper pulling clamp that can move back and forth along the conveying direction of the conveying device 200, and the paper pulling device 400 is used to release the packaging paper from the paper passing gap. The wrapping paper released from the paper gap is pulled onto the conveying device 200; the positioning clamp 500 is located on one side perpendicular to the conveying direction of the conveying device 200, and the positioning clamp 500 reciprocates along the conveying direction perpendicular to the conveying device 200, and the positioning clamp 500 is used to adjust the position of the wrapping paper released to the conveying device 200 along the conveying direction perpendicular to the conveying device 200; the support plate 110 is located on the other side perpendicular to the conveying direction of the conveying device 200, and a folding device 600 is provided on the support plate 110, and the folding device 600 has a rotatable folding plate 610, and the folding plate 610 is used to fold the side of the wrapping paper away from the positioning clamp 500 toward the positioning clamp 500.

[0040] As can be seen from the above, the size of the wrapping paper is adjusted when the wrapping paper is loaded. Specifically, the paper placing device 300 is used to release the wrapping paper to the conveying device 200. The width of the wrapping paper is generally not less than the circumference of the required packaging material. For example, the circumference of the required packaging material is 1 meter, and the required width of the wrapping paper needs to be at least 1 meter so that the wrapping paper can completely wrap the entire material. Preferably, the width of the wrapping paper can be no less than 1.5 meters, so that the wrapping paper has enough overlapping parts after wrapping the material to improve the packaging effect of the material. When the width of the wrapping paper is too large, such as exceeding 1.5 meters, it is necessary to fold the part exceeding 1.5 meters. Specifically, before the wrapping paper is released, it passes through the paper passing gap formed by the paper guide roller 310 and the dotted line knife 320, and the dotted line knife 320 forms a folding dotted line on the wrapping paper. After the wrapping paper is released, the wrapping paper is clamped by the paper pulling clamp and pulled along the length direction of the conveying device 200, so that the wrapping paper is laid on the conveying device 200 after being released, and then the positioning clamp 500 clamps one side of the wrapping paper to drive the wrapping paper to move along the conveying direction perpendicular to the conveying device 200, so that the paper folding virtual line formed on the wrapping paper is close to the folding plate 610, and then the folding plate 610 rotates toward the positioning clamp 500 to fold the wrapping paper 180 degrees along the paper folding virtual line position. In this way, the width of the wrapping paper is shortened by folding the edge of the wrapping paper, thereby adjusting the size of the wrapping paper, and then the material to be packaged is placed on the wrapping paper for packaging. At this time, the phenomenon that wrinkles are easily formed when the wrapping paper is wrapped on the material can be effectively reduced. The wrapping paper with adjusted size is more compact and beautiful when packaging the material, thereby improving the packaging quality.

[0041] The paper placing device 300 is used to unwind the wrapping paper. Naturally, the paper placing device 300 includes an unwinding roller 391, an upper paper feeding roller 392, a lower paper feeding roller 393, a fixed knife and a movable knife 394. The upper paper feeding roller 392 and the lower paper feeding roller 393 are connected to the frame 100 for rotation along the up and down directions. A motor for driving the lower paper feeding roller 393 to rotate is arranged on the frame 100. The fixed knife is fixedly connected to the frame 100, and the movable knife 394 can be close to or away from the fixed knife in the frame 100, thereby realizing the cutting of the wrapping paper. The cylindrical wrapping paper is located outside the unwinding roller 391. After being pulled out, the wrapping paper bypasses the paper guide roller 310, passes through the paper gap and enters between the upper paper feed roller 392 and the lower paper feed roller 393. The upper paper feed roller 392 can press the wrapping paper against the lower paper feed roller 393, and the lower paper feed roller 393 rotates to release the wrapping paper and pass between the movable knife 394 and the fixed knife. When the wrapping paper needs to be cut, the movable knife 394 approaches the fixed knife, and the movable knife 394 and the fixed knife are interlaced to achieve the cutting of the wrapping paper.

[0042] The dotted line knife 320 is a circular blade, and a raised blade edge is arranged on the outer side of the blade for forming dotted lines on the packaging paper, such as saw teeth. The dotted line knife 320 can be directly rotatably connected to the frame 100. At this time, the paper feeding gap formed by the dotted line knife 320 and the paper guide roller 310 is fixed. In order to facilitate the feeding of packaging paper into the paper feeding gap at the beginning, in this embodiment, as shown in FIG. Figure 2 As shown, the paper placing device 300 includes a first lifting drive member 330 and a lifting seat 340. The first lifting drive member 330 is arranged on the frame 100, and the lifting seat 340 is arranged on the first lifting drive member 330. The first lifting drive member 330 can adopt a driving source such as a cylinder, an electric screw or a hydraulic cylinder. The first lifting drive member 330 can drive the lifting seat 340 to move downward toward or upward away from the paper guide roller 310. The dotted line knife 320 is rotatably connected to the lifting seat 340. When it is necessary to feed the packaging paper into the paper feeding gap, the first lifting drive member 330 can drive the lifting seat 340 upward away from the paper guide roller 310. At this time, the paper feeding gap is increased, and the packaging paper can be easily fed in. When it is necessary to send the packaging paper outward, the first lifting drive member 330 drives the lifting seat 340 to move downward close to the paper guide roller 310, and the paper feeding gap is reduced. At this time, the dotted line knife 320 presses the packaging paper against the outside of the paper guide roller 310. As the packaging paper moves, the dotted line knife 320 is driven to rotate and forms a paper folding dotted line on the packaging paper.

[0043] According to the different sizes of the required wrapping paper, the position where the wrapping paper needs to be folded also varies. In order to facilitate the adjustment of the position of the dotted line knife 320, in this embodiment, the paper placing device 300 also includes an adjusting screw rod 350 disposed between the frame 100 and the first lifting drive member 330. The adjusting screw rod 350 can be a hand-cranked screw rod or an electric adjusting screw rod 350. The adjusting screw rod 350 can drive the first lifting drive member 330 to move along the conveying direction perpendicular to the conveying device 200. According to the required size of the wrapping paper, the position of the dotted line knife 320 can be adjusted along the width direction of the conveying device 200 by adjusting the screw rod 350, so that the dotted line of the paper folding can be formed at the corresponding position of the wrapping paper, and different paper folding widths can be formed when the wrapping paper is folded, so as to better meet different usage requirements.

[0044] After wrapping the wrapping paper around the folded edge of the profile, the wrapping paper can be fixed by wrapping the wrapping tape or by gluing the wrapping paper. Specifically, Figure 3As shown, the paper placing device 300 includes a paper guide shell 360, a first glue gun 370 and a second glue gun 380. The paper guide shell 360 is located between the paper guide roller 310 and the conveying device 200. The paper guide shell 360 is surrounded by a guide channel that passes through the conveying direction of the conveying device 200. The first glue gun 370 and the second glue gun 380 are arranged above the paper guide shell 360 at intervals perpendicular to the conveying direction of the conveying device 200. A first avoidance hole is arranged on the top side of the paper guide shell 360 facing the first glue gun 370, and a second avoidance hole is arranged on the top side of the paper guide shell 360 facing the second glue gun 380. After the wrapping paper passes through the paper gap, it is sent out from the guide channel formed by the paper guide shell 360. By guiding the wrapping paper through the guide channel, the wrapping paper can be more accurately directed and sent out, so that the paper pulling clamp can stably clamp the sent wrapping paper. In addition, during the process of sending the wrapping paper out, the first glue gun 370 and the second glue gun 380 can discharge glue from the top of the paper guide shell 360 downward, and the glue passes through the first avoidance hole and the second avoidance hole respectively and then drips onto the wrapping paper. The glue at one place can be folded and bonded to the wrapping paper using the folding plate 610, and the glue at another place can be bonded and fixed after the wrapping paper completes the packaging of the material.

[0045] As a specific structural embodiment of the paper pulling device 400, Figure 6 As shown, the paper pulling device 400 includes a paper pulling translation seat 410, and the paper pulling translation seat 410 can move back and forth on the frame 100 along the length direction of the conveying device 200. The paper pulling clamp includes a lower clamping plate 420 and an upper clamping plate 430 arranged on the paper pulling translation seat 410, and the upper clamping plate 430 can move downward toward or upward away from the lower clamping plate 420 on the paper pulling translation seat 410. Before the packaging paper is pulled and conveyed, the upper clamping plate 430 is in a state away from the lower clamping plate 420. When the packaging paper is released outward, the paper pulling translation seat 410 moves horizontally toward the paper placing device 300, so that the packaging paper enters between the upper clamping plate 430 and the lower clamping plate 420, and then the upper clamping plate 430 moves downward toward the lower clamping plate 420 to clamp the packaging paper, and the paper pulling translation seat 410 moves in a direction away from the paper placing device 300, so that the released packaging paper is flatly laid on the conveying device 200.

[0046] In actual application, a paper pulling translation device is arranged on the frame 100, and the paper pulling translation seat 410 is arranged on the paper pulling translation device. The paper pulling translation device can drive the paper pulling translation seat 410 to move along the length direction of the conveying device 200. The paper pulling translation device is provided with a first paper pulling lifting drive component, and the paper pulling translation seat 410 is arranged on the first paper pulling lifting drive component. The first paper pulling lifting drive component can drive the paper pulling translation seat 410 to move up and down. The paper pulling translation seat 410 is also provided with a second paper pulling lifting drive component, and the upper clamping plate 430 is arranged on the second paper pulling lifting drive component. The second paper pulling lifting drive component can drive the upper clamping plate 430 to move up and down. The paper pulling translation device includes a paper pulling frame, a paper pulling driving motor, a paper pulling gear and a paper pulling rack. The paper pulling frame is slidably connected to the frame 100, the paper pulling driving motor is connected to the paper pulling frame, the paper pulling driving motor drives the paper pulling gear, the paper pulling rack is connected to the frame 100, the paper pulling gear and the paper pulling rack are meshed with each other, when the paper pulling translation seat 410 needs to translate, the paper pulling driving motor drives the paper pulling gear to rotate, and the paper pulling gear moves along the paper pulling rack, thereby driving the paper pulling frame to move along the length direction of the conveying device 200. The first paper pulling lifting driving member and the second paper pulling lifting driving member can use a driving source such as a cylinder, an electric screw or a hydraulic cylinder.

[0047] The positioning gripper 500 is mainly used to adjust the position after clamping one side of the packaging paper. Figure 4 As shown, in this embodiment, the positioning clamp 500 includes a positioning frame 510 and a positioning pressing block 520. The positioning frame 510 can move along the conveying direction perpendicular to the conveying device 200. The positioning frame 510 forms a limited concave angle 511 at the position opposite to the conveying device 200. The positioning pressing block 520 is arranged on the positioning frame 510. The positioning pressing block 520 can move up and down in the limited concave angle 511. When the wrapping paper is laid on the conveying device 200, one side of the wrapping paper is located in the limited concave angle 511. The limited concave angle 511 pre-positions one side of the wrapping paper. Then, the positioning pressing block 520 moves downward to press the wrapping paper tightly and position it in the limited concave angle 511. At this time, the positioning frame 510 can move along the conveying direction perpendicular to the conveying device 200 to adjust the position of the folded paper virtual line. In this way, the position of the wrapping paper along the width direction of the conveying device 200 can be accurately adjusted.

[0048] In practical applications, the positioning frame 510 is slidably connected to the frame 100, and a positioning translation driving member for driving the positioning frame 510 to translate is provided on the frame 100. The positioning translation driving member can adopt a driving source such as a cylinder, an electric screw or a hydraulic cylinder, or a rotatable synchronous belt is provided on the frame 100, and the synchronous belt is fixedly connected to the positioning frame 510, and the synchronous belt is driven to rotate by the positioning driving motor, thereby driving the positioning frame 510 to move. A positioning lifting driving member is provided on the positioning frame 510, and the positioning pressure block 520 is provided on the positioning lifting driving member, and the positioning lifting driving member can adopt a driving source such as a cylinder, an electric screw or a hydraulic cylinder.

[0049] The folding device 600 may be directly provided with a motor for driving the folding plate 610 to rotate, so as to achieve the folding of the packaging paper. In order to better store the folding plate 610 in the support plate 110 when it is not needed, Figure 5As shown, in this embodiment, the folding device 600 includes a paper folding frame 620, a guide shaft 630 and a tension spring 640. The paper folding frame 620 is rotatably connected to the frame 100 at a side close to the conveying device 200. A hole is provided on the support plate 110 at a position facing the paper folding frame 620. The guide shaft 630 is connected to the frame 100 and is located between the paper folding frame 620 and the conveying device 200. The folding plate 610 is a belt-shaped structure. One end of the folding plate 610 is connected to the far side of the paper folding frame 620. On one side of the conveying device 200, the other end of the folding plate 610 extends toward the direction close to the conveying device 200 and downwardly bypasses the guide shaft 630. The tension spring 640 is connected between the bottom end of the folding plate 610 and the frame 100. Of course, a driving motor is arranged in the frame 100, and the driving motor is connected to the origami frame 620. The origami frame 620 can be rotated toward the direction close to the conveying device 200 to protrude from the hole or rotated away from the conveying device 200 to be retracted into the hole. When the wrapping paper is laid on the conveying device 200, the folding plate 610 is in the state of being retracted into the hole, and the folding plate 610 itself does not interfere with the movement of the wrapping paper along the width direction of the conveying device 200. When the wrapping paper needs to be folded along the paper folding imaginary line, the folding frame 620 rotates in the direction close to the conveying device 200, and the folding plate 610 rotates and protrudes out of the hole, and drives the wrapping paper to be folded along the paper folding imaginary line position. The folding plate 610 is a belt-shaped structure, and the tension spring 640 can keep The folding plate 610 is held straightened. When the folding plate 610 rotates to abut against the support plate 110, after the folding plate 610 abuts against the edge of the hole of the support plate 110, it can be further rotated so that the folding plate 610 can press the packaging paper more tightly against the support plate 110, thereby completing the folding of the packaging paper and improving the folding effect of the packaging paper. After completion, the folding frame moves away from the conveying device 200 and is re-entered into the hole to avoid interfering with the next packaging paper loading.

[0050] The frame 100 is also provided with a material clamping and folding device and a material pressing device, the material clamping and folding device includes a first material clamping plate 711, a second material clamping plate 731, a first folding paper board 721, and a second folding paper board 741 located on both sides of the conveying device 200, the first material clamping plate 711 and the second material clamping plate 731 can approach or move away from each other, the first folding paper board 721 is located above the first material clamping plate 711, and the second folding paper board 741 is located above the second material clamping plate 731. When the conveying device 200 moves downward, the first folding paper board 721 and the second folding paper board 741 can approach or move away from each other, the material pressing device is located above the conveying device 200, and the material pressing device has a pressure head 820 that can move up and down.

[0051] In the above embodiment, the wrapping paper is directly pressed against both sides of the material by the first clamping plate 711 and the second clamping plate 731. When the first clamping plate 711 and the second clamping plate 731 are close to each other to press the wrapping paper against the material, if the pressure is too great, it will easily cause damage to the material due to hard pressure. Therefore, in order to better provide pressure for the wrapping paper and reduce the occurrence of crushing the material, in the present embodiment, the first clamping plate 711 and the second clamping plate 731 are respectively provided with a first flexible layer on the side facing each other, and the bottom side of the first folding paper board 721 and the bottom side of the second folding paper board 741 are respectively provided with a second flexible layer. When the conveying device 200 moves downward, the material and the packaging paper move downward as a whole. At this time, the first flexible layer on the first clamping plate 711 and the first flexible layer on the second clamping plate 731 are in contact with the packaging paper respectively, and the two sides of the packaging paper are pressed against the material. The flexible deformation of the first flexible layer can be used to better press the packaging paper onto the material, and prevent the material from being deformed due to excessive pressure. Similarly, when the first folding paper board 721 and the second folding paper board 741 turn over the packaging paper, the second flexible layer on the first folding paper board 721 and the second flexible layer on the second folding paper board 741 are in contact with the packaging paper respectively, and the top of the packaging paper is pressed against the material. The flexible deformation of the second flexible layer can be used to make the packaging paper closer to the top side of the material and fold it, and prevent the material from being deformed due to excessive pressure.

[0052] The first flexible layer and the second flexible layer are mainly used to provide flexible profiling and buffering effects. There are many structural forms. For example, the first flexible layer and the second flexible layer can be sponge or rubber, etc., respectively. In this embodiment, Figure 8 and Fig. 9 As shown, the first flexible layer and the second flexible layer can use brushes respectively. Specifically, the first clamping plate 711 and the second clamping plate 731 are respectively provided with first brushes 732 on the sides facing each other, and the bottom sides of the first folding paper board 721 and the second folding paper board 741 are respectively provided with second brushes 742. When the packaging paper is folded close to the outside of the material, the packaging paper is pressed against the outside of the material by the first brush 732 and the second brush 742, which can provide effective support for the packaging paper to be pressed against the material, and the first brush 732 itself can produce a certain elastic deformation to prevent the material from being crushed, and reduce the friction and pulling phenomenon between the material and the packaging paper when the material moves up.

[0053] The lifting device is mainly used to drive the conveying device 200 to move up and down as a whole. The conveying device 200 is movably arranged on the frame 100 along the up and down direction. The lifting device on the frame 100 is transmission-connected with the conveying device 200 to drive it to move up and down in the frame 100. There are many structural forms of the lifting device. For example, the lifting device can use a cylinder, an electric screw rod or a hydraulic cylinder as a driving source to directly drive the conveying device 200 to move up and down. When the conveying device 200 is large, multiple driving sources can be provided to drive simultaneously, thereby improving the stability of the up and down movement of the conveying device 200. In this embodiment, if Fig.12 As shown, the lifting device includes a linear drive member 230 and a slide 210, the slide 210 is slidably connected to the bottom of the frame 100, the slide 210 is connected to a guide plate 211, the guide plate 211 has a guide bevel 212 extending obliquely upward along the conveying direction of the conveying device 200, a guide wheel 220 is provided at the bottom of the conveying device 200, the guide wheel 220 abuts against the guide bevel 212, the fixed end of the linear drive member 230 is hinged to the frame 100, the movable end of the linear drive member 230 is hinged to the slide 210, the The linear drive member 230 can drive the slide 210 to slide along the length direction of the conveying device 200. In actual applications, when the conveying device 200 is longer, multiple guide plates 211 can be provided on the slide 210. At this time, a guide wheel 220 is also provided at the bottom of the conveying device 200 corresponding to the guide bevel 212 of the multiple guide plates 211. The multiple guide wheels 220 are used to resist the guide bevel 212 of the multiple guide plates 211, so that the conveying device 200 is more stable on the slide 210. The linear drive member 230 can use a cylinder, an electric screw or a hydraulic cylinder as a driving source. The conveying device 200 is pressed toward the guide plate 211 under the action of gravity, and the contact between the guide wheel 220 and the guide plate 211 is used to support the conveying device 200. When the guide wheel 220 is located at the top end position of the guide bevel 212, the conveying device 200 is located at the top end of the stroke. At this time, the process of loading packaging paper and materials can be carried out. When packaging paper is needed to package the materials, the linear drive member 230 drives the slide 210 to slide. At this time, the support height of the guide bevel 212 on the guide wheel 220 is gradually reduced, so that the conveying device 200 gradually moves downward, thereby realizing the sinking of the packaging paper and materials. When the conveying device 200 needs to be raised again, the linear drive member 230 drives the slide 210 to slide in the opposite direction. At this time, the support height of the guide bevel 212 on the guide wheel 220 is gradually increased, so that the conveying device 200 moves up and resets, so that the conveying device 200 can be stably moved up and down.

[0054] There are many ways for the first clamping plate 711 and the second clamping plate 731 to move closer to or farther from each other. For example, both the first clamping plate 711 and the second clamping plate 731 can be moved in the frame 100, or one of the first clamping plate 711 and the second clamping plate 731 is fixed in the frame 100, and the other can be moved in the frame 100. In this embodiment, the first clamping plate 711 is fixed to the frame 100, and the clamping origami device includes a first moving frame 733, a first motor, a first transmission shaft 734, a first gear 735 and a first rack 736, the first movable frame 733 is slidably connected to the frame 100 along the direction of approaching or moving away from the conveying device 200, the second clamping plate 731 is connected to the first movable frame 733, the first transmission shaft 734 is rotatably connected to the frame 100, the first motor drives the first transmission shaft 734, the first gear 735 is synchronously connected to the first transmission shaft 734, the first rack 736 is connected to the first movable frame 733, and the first rack 736 and the first gear 735 are meshed with each other. The first clamping plate 711 is fixed on the frame 100. When the first clamping plate 711 and the second clamping plate 731 need to be moved closer to or further away from each other, the second clamping plate 731 is relied upon to be moved. Specifically, the first motor drives the first transmission shaft 734 to rotate, so that the first gear 735 on the first transmission shaft 734 rotates synchronously. Since the first gear 735 and the first rack 736 are meshed with each other, the first rack 736 can be provided with a driving force to move closer to or away from the conveying device 200, thereby making the second clamping plate 731 closer to or further away from the first clamping plate 711. In this way, the distance between the first clamping plate 711 and the second clamping plate 731 can be stably and accurately controlled to adapt to different material sizes.

[0055] In actual applications, according to the length of the material to be packaged or the length required by the entire machine, multiple first clamping plates 711 and second clamping plates 731 can be arranged at intervals along the length direction of the conveying device 200, and the positions of the multiple first clamping plates 711 and the multiple second clamping plates 731 correspond to each other. At this time, for the transmission of the multiple second clamping plates 731, multiple first mobile frames 733 can be arranged at corresponding positions in the frame 100, and the multiple second clamping plates 731 are respectively connected to the multiple first mobile frames 733, and the first motor drives the multiple first gears 735 to rotate through the first transmission shaft 734, and the multiple first gears 735 are respectively engaged with the multiple first racks 736, thereby driving the multiple second clamping plates 731 to move in translation at the same time.

[0056] The material-clamping origami device has a driving source that can drive the first origami paper 721 to move. For example, a driving source that can drive translational movement is provided in the frame 100, such as a cylinder, an electric screw or a hydraulic cylinder, and the first origami paper 721 is directly driven by such a driving source, thereby driving the first origami paper 721 to move translationally. In this embodiment, the material-clamping origami device includes a second motor, a second transmission shaft 722, a second gear 723 and a second rack 724. The first origami paper 721 is slidably connected to the frame 100 in a direction approaching or moving away from the conveying device 200, the second transmission shaft 722 is rotatably connected to the frame 100, the second gear 723 is synchronously connected to the second transmission shaft 722, the second rack 724 is connected to the first origami paper 721, and the second rack 724 and the second gear 723 are meshed with each other. When the first folding paper board 721 slides in the direction approaching the conveying device 200, the packaging paper can be folded. When the first folding paper board 721 slides in the direction away from the conveying device 200, it is reset after folding. Specifically, the second motor drives the second transmission shaft 722 to rotate, so that the second gear 723 on the second transmission shaft 722 rotates synchronously. Since the second gear 723 and the second rack 724 are meshed with each other, the second rack 724 can be provided with a driving force to move closer to or away from the conveying device 200, thereby making the first folding paper board 721 close to or away from the conveying device 200. In this way, the distance that the first folding paper board 721 needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0057] Similarly, the material-clamping origami device has a driving source that can drive the second origami paper 741 to move. For example, a driving source that can drive translational movement is provided in the frame 100, such as a cylinder, an electric screw or a hydraulic cylinder, and the second origami paper 741 is directly driven by such a driving source, thereby driving the second origami paper 741 to move translationally. In this embodiment, the material-clamping origami device includes a third motor, a third transmission shaft 743, a third gear 745 and a third rack 746. The first origami paper 721 is slidably connected to the frame 100 in a direction approaching or moving away from the conveying device 200, the third transmission shaft 743 is rotatably connected to the frame 100, the third gear 745 is synchronously connected to the third transmission shaft 743, the third rack 746 is connected to the first origami paper 721, and the third rack 746 and the third gear 745 are meshed with each other. When the second folding paper board 741 slides in the direction approaching the conveying device 200, the packaging paper can be folded. When the second folding paper board 741 slides in the direction away from the conveying device 200, it is reset after folding the paper. Specifically, the third motor drives the third transmission shaft 743 to rotate, so that the third gear 745 on the third transmission shaft 743 rotates synchronously. Since the third gear 745 and the third rack 746 are engaged with each other, the third rack 746 can be provided with a driving force to move closer to or away from the conveying device 200, thereby making the second folding paper board 741 close to or away from the conveying device 200. In this way, the distance that the second folding paper board 741 needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0058] In practical applications, according to the length of the material to be packaged or the length required by the entire machine, multiple first folding paper boards 721 and second folding paper boards 741 can be arranged at intervals along the length direction of the conveying device 200, and the positions of the multiple first folding paper boards 721 and the multiple second folding paper boards 741 correspond to each other. At this time, for the movement of the multiple first folding paper boards 721 and the second folding paper boards 741, second racks 724 can be respectively provided on the multiple first folding paper boards 721, and third racks 746 can be respectively provided on the multiple second folding paper boards 741. Correspondingly, the positions of the second transmission shaft 722 corresponding to the multiple second racks 724 are respectively synchronously connected with second gears 723, and the multiple second gears 723 and the multiple second racks 724 are respectively meshed with each other. The positions of the third transmission shaft 743 corresponding to the multiple third racks 746 are respectively synchronously connected with third gears 745, and the multiple third gears 745 and the multiple third racks 746 are respectively meshed with each other, thereby driving the multiple first folding paper boards 721 and the multiple second folding paper boards 741 to move in translation at the same time.

[0059] The first folding paper board 721 and the second folding paper board 741 can be located at the same height. At this time, when it is necessary to fold the portion of the packaging paper located on the top side of the material, the ends of the stroke where the first folding paper board 721 and the second folding paper board are close to each other are in a state of tending to abut each other. The first folding paper board 721 and the second folding paper board 741 should not collide with each other as much as possible to avoid affecting the structural stability. In order to better prevent the first folding paper board 721 and the second folding paper board 741 from colliding with each other, in this embodiment, the first folding paper board 721 and the second folding paper board 741 are staggered with each other in the up and down directions. Naturally, the lengths of the second brush 742 on the bottom side of the first folding paper board 721 and the second brush 742 on the bottom side of the second folding paper board 741 should be able to meet the requirements for folding the packaging paper. For example, the bottom end of the second brush 742 on the bottom side of the first folding paper board 721 and the bottom end of the second brush 742 on the bottom side of the second folding paper board 741 are located on the same horizontal plane. When the first folding paper board 721 and the second folding paper board 741 fold the wrapping paper, the lower one folds the side of the wrapping paper first, and then the higher one folds the other side of the wrapping paper. For example, after the lower first folding paper board 721 completes the folding of one side of the wrapping paper, the higher second folding paper board 741 folds the other side of the wrapping paper. By using the upper and lower staggered avoidance of the first folding paper board 721 and the second folding paper board 741, it can be ensured that the folding of the wrapping paper is in place and prevent mutual interference and collision. In actual application, the first folding paper board 721 is arranged below the support plate 110, the height of the first folding paper board 721 is lower than the second folding paper board 741, and the support plate 110 and the second folding paper board 741 are flush with each other. At this time, the wrapping paper can be better laid flat on the second folding paper board 741 and the support plate 110.

[0060] The pressing device has a driving source that can drive the pressing head 820 to move up and down. Specifically, the pressing device includes a pressing lifting driving member 810, which is connected to the pressing head 820. The pressing lifting driving member 810 can drive the pressing head 820 to move up and down. The pressing lifting driving member can use a cylinder, an electric screw or a hydraulic cylinder as a driving source. The pressing lifting driving member 810 is connected to the frame 100 to provide a driving force for the pressing head 820 to move in the up and down direction. When the packaging paper and the material need to move down, the pressing lifting driving member 810 drives the pressing head 820 to press against the material to assist the packaging paper and the material to move down as a whole. After completion, when the pressing head is moved down to the right position, the pressing lifting driving member 810 drives the pressing head 820 to move up and reset.

[0061] The conveying device 200 is mainly used to support the material and send the packaged material out after packaging. Its structural forms are various. For example, the conveying device 200 uses a belt conveyor. At this time, if it is necessary to use the first clamping plate 711 and the second clamping plate 731 to press the packaging paper on both sides of the material, after the material is placed on the conveying device 200, the width of both sides of the conveyor belt needs to be smaller than the width of the material. Only then can the first clamping plate 711 and the second clamping plate 731 be used to press the packaging paper on both sides of the material directly from the bottom position on both sides of the material to avoid interference with the conveyor belt when clamping the material. Preferably, the conveying device 200 can use a roller conveyor, which has multiple conveying rollers spaced apart along its length direction. In this case, the first clamping plate 711 and the second clamping plate 731 can be set between two spaced conveying rollers, and the spacing distance between the two conveying rollers needs to be greater than the width of the first clamping plate 711 or the second clamping plate 731, so as to avoid the movement of the first clamping plate 711 and the second clamping plate 731. In this embodiment, the width of the material does not need to be greater than the length of the conveying roller itself, and the first clamping plate 711 and the second clamping plate 731 will not interfere with the conveying roller when they are close to each other, thereby better improving the overall applicability.

[0062] In practical applications, a wrapping device 900 is further provided at one side of the conveying end of the conveying device 200 , and the wrapping device 900 is used for wrapping the wrapping paper.

[0063] A profile packaging method, using the above-mentioned profile packaging machine, includes but is not limited to the following steps:

[0064] Step S100, obtaining the packaging paper size required for the packaging profile;

[0065] Step S200, adjusting the position of the dotted line knife 320 according to the size of the packaging paper, passing the packaging paper through the paper feeding gap, so that a folded paper dotted line is formed on the packaging paper, and the packaging paper is pulled out to the conveying device 200 by the paper pulling clamp;

[0066] Step S300, the positioning gripper 500 clamps one side of the packaging paper and drives the packaging paper to move, so that the folding imaginary line on the packaging paper is close to the folding plate 610, and the folding plate 610 folds the packaging paper along the folding imaginary line;

[0067] Step S400, feeding the profile onto the packaging paper, and folding the packaging paper along the profile shape for packaging.

[0068] When using the above-mentioned profile packaging machine, the position of the dotted line knife 320 can be adjusted according to the different sizes of packaging paper required for packaging profiles, so that when the packaging paper passes through the dotted line knife 320, a folded paper dotted line is formed at the corresponding position. After the packaging paper is released, the packaging paper is clamped by the paper pulling clamp and pulled along the length direction of the conveying device 200, so that the packaging paper is laid on the conveying device 200 after being released, and then the position adjustment clamp 500 clamps one side of the packaging paper to drive the packaging paper to move along the conveying direction perpendicular to the conveying device 200, so that the packaging paper is formed on the packaging paper. The formed paper folding imaginary line is close to the folding plate 610, and then the folding plate 610 is rotated toward the position adjustment clamp 500 to fold the packaging paper 180 degrees along the paper folding imaginary line. In this way, according to the size of different materials, the width of the packaging paper can be shortened by folding the edges of the packaging paper, so as to adjust the size of the packaging paper, and then the material to be packaged is placed on the packaging paper for packaging. At this time, the phenomenon of wrinkles when the packaging paper is wrapped on the material can be effectively reduced. The packaging paper with adjusted size is more compact and beautiful when packaging the material, thereby improving the quality of profile packaging.

[0069] In step S400, the packaging paper is folded along the profile shape for packaging, including:

[0070] S410, the conveying device 200 moves downward, driving the packaging paper and the profile to move downward relative to the first clamping plate 711 and the second clamping plate 731;

[0071] S420, the first brush 732 on the first clamping plate 711 and the first brush 732 on the second clamping plate 731 respectively press the two sides of the wrapping paper on the two sides of the profile, so that the two sides of the wrapping paper are folded upward along the two sides of the profile;

[0072] S430, after the conveying device 200 moves down to its position, the first folding paper board 721 and the second folding paper board 741 are close to each other, and the packaging paper is pressed tightly against the top side of the profile by using the second brush 742 on the bottom side of the first folding paper board 721 and the second brush 742 on the bottom side of the second folding paper board 741, so that the folded edge of the packaging paper is wrapped around the top side of the profile.

[0073] In this way, by sinking the material so that the wrapping paper tightly wraps the two sides of the material from bottom to top, the wrapping paper wraps the material more tightly, thereby improving the packaging quality of the material, helping to reduce the overall volume and facilitating the transportation and movement of the material.
