Description

Technical Field

[0001] This utility model relates to a packaging equipment, and more particularly to a sunken packaging mechanism and a profile packaging machine. Background Technology

[0002] When packaging strip materials such as profiles, they need to be arranged, stacked, and then wrapped with packaging paper before leaving the factory. This wrapping process typically involves placing the bundled strips on a flat sheet of packaging paper and then folding the paper over the material using a folding mechanism. However, this method results in poor sealing, making the material prone to scattering during transport and movement. Furthermore, the overall volume of the package is difficult to reduce. Therefore, there is a pressing need for equipment that can better package materials. Utility Model Content

[0003] The purpose of this utility model is to provide a sunken packaging mechanism and a profile packaging machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A sunken packaging mechanism includes: a frame; a conveying device movably connected to the frame in a vertical direction, wherein a lifting device is provided between the conveying device and the frame, and the lifting device can drive the conveying device to move up and down; a clamping and folding device, including a first clamping plate and a second clamping plate located on both sides of the conveying device, and a first folding board and a second folding board, wherein the first clamping plate and the second clamping plate can move closer to or further away from each other, the first folding board is located above the first clamping plate, and the second folding board is located above the second clamping plate, and the first folding board and the second folding board can move closer to or further away from each other when the conveying device moves downward; and a pressing device, disposed within the frame above the conveying device, wherein the pressing device has a pressing head that can move up and down.

[0006] This technical solution has at least the following beneficial effects: In the initial state, the conveying device is in the upward movement to the top of its stroke within the frame. At this time, the packaging paper is first laid on the conveying device, and the material to be packaged is also placed on the packaging paper. The conveying device supports and supports the material. Then, the relative positions of the first clamping plate and the second clamping plate are adjusted. By bringing the first clamping plate and the second clamping plate closer together, the space formed by them is reduced to accommodate the width of smaller materials. Alternatively, by moving the first clamping plate and the second clamping plate further apart, the space formed by them is expanded to accommodate the width of larger materials. Then, the lifting device drives the conveying device to move downward, and the pressure head in the pressing device presses down against the material to ensure that the material and the packaging paper move downward as a whole. During this process, the packaging paper is located on both sides of the material and is pressed down by the first clamping plate and the second clamping plate. The packaging paper is folded along the material, pressing it tightly against the surface from bottom to top. Then, the first and second folding boards are brought closer together, and the portion of the packaging paper protruding from the top surface of the material is horizontally folded over, covering the material completely. After this, the first and second folding boards are reset in a direction away from each other, as are the first and second clamping plates. The conveyor then moves upwards and resets, sending the material out along its conveying direction for subsequent packaging processes. This method of lowering the material to ensure the packaging paper tightly wraps the material from bottom to top improves packaging quality, reduces overall volume, and facilitates transport and movement.

[0007] As a further improvement to the above technical solution, a first flexible layer is provided on the side of the first clamping plate and the second clamping plate facing each other, and a second flexible layer is provided on the bottom side of the first folding paperboard and the bottom side of the second folding paperboard.

[0008] As a further improvement to the above technical solution, the first flexible layer is a first brush, and the second flexible layer is a second brush.

[0009] As a further improvement to the above technical solution, the pressing device includes a pressing lifting drive component, which drives the pressing head and can move the pressing head up and down.

[0010] As a further improvement to the above technical solution, the lifting device includes a linear drive and a slide. The slide is slidably connected to the bottom of the frame, and a guide plate is connected to the slide. The guide plate has a guide slope extending upward along the length direction of the conveying device. A guide wheel is provided at the bottom of the conveying device, and the guide wheel abuts against the guide slope. The fixed end of the linear drive is hinged to the frame, and the movable end of the linear drive is hinged to the slide. The linear drive can drive the slide to slide along the length direction of the conveying device.

[0011] As a further improvement to the above technical solution, the first clamping plate is fixed to the frame, and the clamping and folding device includes a first moving frame, a first motor, a first transmission shaft, a first gear and a first rack. The first moving frame is slidably connected to the frame in a direction close to or away from the conveying device. The second clamping plate is connected to the first moving frame. The first transmission shaft is rotatably connected to the frame. The first motor drives the first transmission shaft. The first gear is synchronously connected to the first transmission shaft. The first rack is connected to the first moving frame, and the first rack and the first gear mesh with each other.

[0012] As a further improvement to the above technical solution, the clamping and folding device includes a second motor, a second drive shaft, a second gear, and a second rack. The first folding board is slidably connected to the frame in a direction close to or away from the conveying device. The second drive shaft is rotatably connected to the frame. The second gear is synchronously connected to the second drive shaft. The second rack is connected to the first folding board, and the second rack and the second gear mesh with each other.

[0013] As a further improvement to the above technical solution, the clamping and folding device includes a third motor, a third transmission shaft, a third gear, and a third rack. The first folding board is slidably connected to the frame in a direction close to or away from the conveying device. The third transmission shaft is rotatably connected to the frame. The third gear is synchronously connected to the third transmission shaft. The third rack is connected to the first folding board, and the third rack and the third gear mesh with each other.

[0014] As a further improvement to the above technical solution, the first folding paperboard and the second folding paperboard are staggered in the vertical direction.

[0015] A profile packaging machine includes: the aforementioned sunken packaging mechanism; a paper feeding device located on one side of the conveying start end of the conveying device, the paper feeding device being used to feed packaging paper to the conveying device; and a wrapping device located on one side of the conveying end of the conveying device, the wrapping device being used to wrap the packaging paper.

[0016] This technical solution has at least the following beneficial effects: When packaging profiles, the paper feeding device first feeds the packaging paper from one side of the conveying device, so that the packaging paper is laid flat on the conveying device. Then, the profile material to be packaged is placed in, and the sunken packaging mechanism uses the packaging paper to package the profile material. After the packaging is completed, the wrapping device wraps the packaging paper. After the packaging is completed, the conveying device sends the whole thing out. Because the sunken packaging mechanism sinks the profile material so that the packaging paper wraps tightly to both sides of the profile material from bottom to top, the packaging paper wraps the profile material more tightly, thereby improving the packaging quality of the profile material, reducing the overall volume, and facilitating the transportation and movement of the profile material.

[0036] Reference Figure 1 A sunken packaging mechanism includes a frame 100, a conveying device 200, a clamping and folding device 900, and a pressing device. The conveying device 200 is movably connected to the frame 100 in a vertical direction. A lifting device is provided between the conveying device 200 and the frame 100, and the lifting device can drive the conveying device 200 to move up and down. The clamping and folding device 900 includes a first clamping plate 311, a second clamping plate 331 located on both sides of the conveying device 200, and a first folding plate 321 and a second folding plate 331. 41. The first clamping plate 311 and the second clamping plate 331 can move closer to or further away from each other. The first folding plate 321 is located above the first clamping plate 311, and the second folding plate 341 is located above the second clamping plate 331. When the conveying device 200 moves downward, the first folding plate 321 and the second folding plate 341 can move closer to or further away from each other. The pressing device is located inside the frame 100 above the conveying device 200. The pressing device has a pressing head 420 that can move up and down.

[0037] As described above, in the initial state, the conveying device 200 is in the upward movement to the top of its stroke within the frame 100. At this time, the packaging paper is first laid on the conveying device 200, and the material to be packaged is also placed on the packaging paper. The conveying device 200 supports and supports the material. Generally, the width of the packaging paper is not less than the outer perimeter of the cross-section of the material to be packaged. For example, if the outer perimeter of the cross-section of the material to be packaged is 1 meter, the width of the packaging paper needs to be at least 1 meter so that the packaging paper completely wraps the entire material. Preferably, the width of the packaging paper can be no less than 1.5 meters so that the packaging paper has sufficient overlap after wrapping the material to improve the packaging effect. Then, the relative positions of the first clamping plate 311 and the second clamping plate 331 are adjusted. By bringing the first clamping plate 311 and the second clamping plate 331 closer together, the space formed by the two is reduced to accommodate the width of smaller materials. Alternatively, the first clamping plate 311 and the second clamping plate 331 can be adjusted. The materials are relatively far apart, expanding the space between them to accommodate the width of larger materials. Then, the lifting device drives the conveying device 200 to move downwards, and the pressing head 420 in the pressing device presses down on the material to ensure that the material and the packaging paper move downwards as a whole. During this process, the packaging paper is pressed against the material by the first clamping plate 311 and the second clamping plate 331 on both sides of the material, realizing the folding of the packaging paper and making the packaging paper fold tightly against the surface of the object from bottom to top. Then, the first folding plate 321 and the second folding plate 341 move closer to each other, and the part of the packaging paper protruding from the top surface of the material is folded horizontally so that the packaging paper covers the top surface of the material, realizing the wrapping of the material. After completion, the first folding plate 321 and the second folding plate 341 are reset in the direction of mutual distance, and the first clamping plate 311 and the second clamping plate 331 are also reset in the direction of mutual distance. The conveying device 200 moves upwards and resets. Then, the conveying device 200 sends the material out along the conveying direction of the conveying device 200 for subsequent packaging processes. By sinking the material so that the packaging paper tightly wraps around both sides of the material from bottom to top, the packaging paper adheres more tightly to the material, thereby improving the quality of the packaging, reducing the overall volume, and facilitating the transportation and movement of the material.

[0038] In the above-mentioned scheme where the first clamping plate 311 and the second clamping plate 331 clamp the material on both sides, unlike clamping structures that only use rollers or clamping blocks with a small pressure area on the material, the first clamping plate 311 and the second clamping plate 331 can keep the packaging paper tightly attached to both sides of the material during the downward movement of the material. In conjunction with the downward pressure of the pressure head 420, it can ensure that the material is moved down and packaged in place while the first clamping plate 311 and the second clamping plate 331 press the packaging paper against both sides of the material. Therefore, by using the action of the pressure head 420 in conjunction with the first clamping plate 311 and the second clamping plate 331, the packaging paper can be tightly packaged on both sides of the material.

[0039] The conveying device 200 is mainly used to support and carry the materials and to send the packaged materials out after packaging. It has various structural forms. For example, if the conveying device 200 uses a belt conveyor, and it is necessary to use the first clamping plate 311 and the second clamping plate 331 to press the packaging paper on both sides of the material, after the material is placed in the conveying device 200, the width of the conveyor belt on both sides needs to be smaller than the width of the material so that the first clamping plate 311 and the second clamping plate 331 can directly press the packaging paper on both sides of the material from the bottom position on both sides to avoid interfering with the conveyor belt when clamping the material. Preferably, the conveying device 200 can be a roller conveyor with multiple conveying rollers spaced apart along its length. In this case, the first clamping plate 311 and the second clamping plate 331 can be placed between two spaced conveying rollers. The distance between the two conveying rollers needs to be greater than the width of the first clamping plate 311 or the second clamping plate 331, so as to avoid the movement of the first clamping plate 311 and the second clamping plate 331. In this embodiment, the width of the material does not need to be greater than the length of the conveying roller itself. When the first clamping plate 311 and the second clamping plate 331 are close to each other, they will not interfere with the conveying roller, thus improving the overall applicability.

[0040] In the above embodiment, the packaging paper is directly pressed against both sides of the material by the first clamping plate 311 and the second clamping plate 331. When the first clamping plate 311 and the second clamping plate 331 approach each other and press the packaging paper against the material, if the pressure is too high, it is easy to cause damage to the material due to hard pressure. Therefore, in order to better provide pressure against the packaging paper and reduce the occurrence of material damage, in this embodiment, the first clamping plate 311 and the second clamping plate 331 are respectively provided with a first flexible layer on the side facing each other, and the bottom side of the first folding paper 321 and the bottom side of the second folding paper 341 are respectively provided with a second flexible layer. When the conveyor 200 moves downward, the material and packaging paper move downward as a whole. At this time, the first flexible layer on the first clamping plate 311 and the first flexible layer on the second clamping plate 331 come into contact with the packaging paper, pressing the two sides of the packaging paper against the material. By utilizing the flexible deformation of the first flexible layer, the packaging paper can be pressed more tightly against the material, and the phenomenon of material deformation caused by excessive pressure can be prevented. Similarly, when the first folding plate 321 and the second folding plate 341 flip the packaging paper, the second flexible layer on the first folding plate 321 and the second flexible layer on the second folding plate 341 come into contact with the packaging paper, pressing the top of the packaging paper against the material. By utilizing the flexible deformation of the second flexible layer, the packaging paper can be folded more tightly against the top side of the material, and the phenomenon of material deformation caused by excessive pressure can be prevented.

[0041] The first and second flexible layers are mainly used to provide flexible conforming and cushioning effects. They can have various structural forms; for example, the first and second flexible layers can be sponge or rubber, respectively. In this embodiment, for example... Figure 3 and Figure 4 As shown, the first flexible layer is a first brush 332, that is, a first brush 332 is respectively provided on the side of the first clamping plate 311 and the second clamping plate 331 facing each other. The second flexible layer is a second brush 342, that is, a second brush 342 is respectively provided on the bottom side of the first folding plate 321 and the bottom side of the second folding plate 341. The first brush 332 is respectively provided on the first clamping plate 311 and the second clamping plate 331 as the first flexible layer. Similarly, the second brush 342 is respectively provided on the bottom side of the first folding plate 321 and the bottom side of the second folding plate 341 as the second flexible layer. When the packaging paper is folded tightly against the outside of the material, the first brush 332 and the second brush 342 press the packaging paper against the outside of the material, which can provide effective support for the packaging paper to press against the material. The first brush 332 itself can generate a certain elastic deformation to prevent the material from being crushed, and also reduce the phenomenon of friction and pulling between the material and the packaging paper when it moves upward.

[0042] The lifting device is mainly used to drive the conveyor device 200 to move up and down as a whole. The conveyor device 200 is movably mounted on the frame 100 in the vertical direction. The lifting device on the frame 100 is connected to the conveyor device 200 through a transmission to drive it to move up and down within the frame 100. The lifting device can have various structural forms. For example, the lifting device can use a cylinder, electric screw, or hydraulic cylinder as a drive source to directly drive the conveyor device 200 to move up and down. When the conveyor device 200 is large, multiple drive sources can be set up to drive it simultaneously, thereby improving the stability of the conveyor device 200's vertical movement. In this embodiment, such as... Figure 2As shown, the lifting device includes a linear drive 230 and a slide 210. The slide 210 is slidably connected to the bottom of the frame 100. A guide plate 211 is connected to the slide 210. The guide plate 211 has a guide inclined side 212 extending obliquely upward along the length direction of the conveying device 200. A guide wheel 220 is provided at the bottom of the conveying device 200, and the guide wheel 220 abuts against the guide inclined side 212. The fixed end of the linear drive 230 is hinged to the frame 100, and the movable end of the linear drive 230 is hinged to the slide 210. The linear drive 230 can drive the carriage 210 to slide along the length of the conveying device 200. In practical applications, when the conveying device 200 is long, multiple guide plates 211 can be provided on the carriage 210. At this time, guide wheels 220 are also provided at the bottom of the conveying device 200 corresponding to the guide slopes 212 of the multiple guide plates 211. The multiple guide wheels 220 abut against the guide slopes 212 of the multiple guide plates 211, thereby making the conveying device 200 more stable on the carriage 210. The linear drive 230 can be a cylinder, electric screw, or hydraulic cylinder as the drive source. Under the action of gravity, the conveying device 200 presses against the guide plate 211, and the guide wheel 220 supports the conveying device 200 by contacting the guide plate 211. When the guide wheel 220 is at the top of the guide inclined side 212, the conveying device 200 is at the top of its stroke, and the process of feeding packaging paper and materials can be carried out. When packaging paper is needed to package the materials, the linear drive 230 drives the slide 210 to slide. At this time, the support height of the guide inclined side 212 on the guide wheel 220 gradually decreases, so that the conveying device 200 gradually moves down, thereby realizing the sinking of the packaging paper and materials. When the conveying device 200 needs to be raised again, the linear drive 230 drives the slide 210 to slide in the opposite direction. At this time, the support height of the guide inclined side 212 on the guide wheel 220 gradually increases, so that the conveying device 200 moves up and resets. In this way, the stable up and down movement of the conveying device 200 can be achieved.

[0043] There are various ways in which the first clamping plate 311 and the second clamping plate 331 can move closer to or further away from each other. For example, both the first clamping plate 311 and the second clamping plate 331 can move within the frame 100, or one of the first clamping plate 311 and the second clamping plate 331 is fixed within the frame 100, while the other can move within the frame 100. In this embodiment, the first clamping plate 311 is fixed to the frame 100. The clamping and folding device 900 includes a first moving frame 333, a first motor, a first transmission shaft 334, a first gear 335, and a first... A rack 336 is provided. The first movable frame 333 is slidably connected to the frame 100 in a direction close to or away from the conveying device 200. The second clamping plate 331 is connected to the first movable frame 333. The first drive shaft 334 is rotatably connected to the frame 100. The first motor is connected to the first drive shaft 334. The first gear 335 is synchronously connected to the first drive shaft 334. The first rack 336 is connected to the first movable frame 333. The first rack 336 and the first gear 335 mesh with each other. The first clamping plate 311 is fixed on the frame 100. When it is necessary to move the first clamping plate 311 and the second clamping plate 331 closer or further apart, the movement of the second clamping plate 331 is achieved. Specifically, the first motor drives the first transmission shaft 334 to rotate, causing the first gear 335 on the first transmission shaft 334 to rotate synchronously. Since the first gear 335 meshes with the first rack 336, it can provide a driving force to the first rack 336 to move closer or further away from the conveying device 200, thereby causing the second clamping plate 331 to move closer or further away from the first clamping plate 311. In this way, the distance between the first clamping plate 311 and the second clamping plate 331 can be stably and accurately controlled to adapt to different material sizes.

[0044] In practical applications, depending on the length of the material to be packaged or the length required for the whole machine, multiple first clamping plates 311 and second clamping plates 331 can be spaced apart along the length of the conveying device 200, and the positions of multiple first clamping plates 311 and multiple second clamping plates 331 correspond to each other. At this time, for the transmission of multiple second clamping plates 331, multiple first moving frames 333 can be set at corresponding positions in the frame 100, and multiple second clamping plates 331 are respectively connected to multiple first moving frames 333. The first motor drives multiple first gears 335 to rotate through the first transmission shaft 334, and the multiple first gears 335 mesh with multiple first racks 336 respectively, thereby driving multiple second clamping plates 331 to move horizontally at the same time.

[0045] The clamping and folding device 900 has a drive source that can move the first folding board 321. For example, a drive source that can move translationally is provided in the frame 100, such as a cylinder, electric screw, or hydraulic cylinder. The first folding board 321 is directly driven by such a drive source, thereby moving the first folding board 321 translationally. In this embodiment, the clamping and folding device 900 includes a second motor, a second transmission shaft 322, a second gear 323, and a second rack 324. The first folding board 321 is slidably connected to the frame 100 in a direction close to or away from the conveying device 200. The second transmission shaft 322 is rotatably connected to the frame 100. The second gear 323 is synchronously connected to the second transmission shaft 322. The second rack 324 is connected to the first folding board 321, and the second rack 324 and the second gear 323 mesh with each other. When the first folding paperboard 321 slides towards the conveyor 200, the packaging paper can be folded. When the first folding paperboard 321 slides away from the conveyor 200, the folded paperboard is reset. Specifically, the second motor drives the second transmission shaft 322 to rotate, causing the second gear 323 on the second transmission shaft 322 to rotate synchronously. Since the second gear 323 and the second rack 324 mesh with each other, the second rack 324 can be provided with a driving force to move towards or away from the conveyor 200, thereby causing the first folding paperboard 321 to move towards or away from the conveyor 200. In this way, the distance that the first folding paperboard 321 needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0046] Similarly, the clamping and folding device 900 has a drive source that can move the second folding board 341. For example, a drive source that can drive translational movement is provided in the frame 100, such as a cylinder, electric lead screw, or hydraulic cylinder. This type of drive source directly drives the second folding board 341, thereby causing the second folding board 341 to move translationally. In this embodiment, the clamping and folding device 900 includes a second motor, a second transmission shaft 322, a second gear 323, and a second rack 324. The device 00 includes a third motor, a third drive shaft 343, a third gear 345, and a third rack 346. The first folding board 321 is slidably connected to the frame 100 in a direction close to or away from the conveying device 200. The third drive shaft 343 is rotatably connected to the frame 100. The third gear 345 is synchronously connected to the third drive shaft 343. The third rack 346 is connected to the first folding board 321, and the third rack 346 and the third gear 345 mesh with each other. When the second folding board 341 slides towards the conveyor 200, the packaging paper can be folded. When the second folding board 341 slides away from the conveyor 200, the folded paper is reset. Specifically, the third motor drives the third transmission shaft 343 to rotate, so that the third gear 345 on the third transmission shaft 343 rotates synchronously. Since the third gear 345 and the third rack 346 mesh with each other, the third rack 346 can provide a driving force to the third rack 346 as it moves towards or away from the conveyor 200, thereby making the second folding board 341 move towards or away from the conveyor 200. In this way, the distance that the second folding board 341 needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0047] In practical applications, depending on the length of the material to be packaged or the length required for the entire machine, multiple first folding cardboard 321 and second folding cardboard 341 can be spaced apart along the length of the conveying device 200, and the positions of the multiple first folding cardboard 321 and multiple second folding cardboard 341 correspond to each other. At this time, for the movement of the multiple first folding cardboard 321 and multiple second folding cardboard 341, a second rack 324 can be provided on each of the multiple first folding cardboard 321, and a third rack 346 can be provided on each of the multiple second folding cardboard 341. Correspondingly, a second gear 323 is synchronously connected to the position of the multiple second racks 324 on the second drive shaft 322, and the multiple second gears 323 mesh with the multiple second racks 324 respectively. A third gear 345 is synchronously connected to the position of the multiple third racks 346 on the third drive shaft 343, and the multiple third gears 345 mesh with the multiple third racks 346 respectively, thereby driving the multiple first folding cardboard 321 and multiple second folding cardboard 341 to move horizontally at the same time.

[0048] The first folding board 321 and the second folding board 341 can be located at the same height. When it is necessary to fold the part of the packaging paper located on the top side of the material, the ends of the strokes of the first folding board 321 and the second folding board 341 tend to abut each other. The first folding board 321 and the second folding board 341 should not collide with each other as much as possible to avoid affecting the structural stability. In order to better prevent the first folding board 321 and the second folding board 341 from colliding with each other, in this embodiment, the first folding board 321 and the second folding board 341 are staggered in the vertical direction. Naturally, the lengths of the second brush 342 on the bottom side of the first folding board 321 and the second brush 342 on the bottom side of the second folding board 341 should be able to meet the requirements of folding the packaging paper. For example, the bottom ends of the second brush 342 on the bottom side of the first folding board 321 and the second brush 342 on the bottom side of the second folding board 341 are located on the same horizontal plane. When the first folding board 321 and the second folding board 341 fold the packaging paper, the one with the lower height folds one side of the packaging paper first, and then the one with the higher height folds the other side. For example, after the first folding board 321, which is shorter, completes the folding of one side of the packaging paper, the second folding board 341, which is taller, folds the other side. By using the staggered arrangement of the first folding board 321 and the second folding board 341, the packaging paper can be folded in place and interference or collision can be prevented. In practical applications, in order to better lay the packaging paper flat, a tray can be set above the lower folding board in the frame 100. For example, when the height of the first folding board 321 is lower than that of the second folding board 341, a tray can be set above the first folding board 321 in the frame 100. The tray is flush with the second folding board 341, so that the packaging paper can be laid flatter on the second folding board 341 and the tray.

[0049] The pressing device includes a drive source that can move the pressing head 420 up and down. Specifically, the pressing device includes a pressing lifting drive 410, which drives the pressing head 420. The pressing lifting drive 410 can move the pressing head 420 up and down. The pressing lifting drive can use a cylinder, electric screw, or hydraulic cylinder as the drive source. The pressing lifting drive 410 is connected to the frame 100 and provides a driving force for the pressing head 420 to move up and down. When the packaging paper and material need to move down, the pressing lifting drive 410 drives the pressing head 420 to press against the material, assisting the packaging paper and material to move down as a whole. After the material has moved down to the correct position, the pressing lifting drive 410 drives the pressing head 420 to move up and reset.

[0050] like Figure 5 , Figure 10 , Figure 11 and Figure 12As shown, a profile packaging machine includes: the aforementioned sunken packaging mechanism; a paper feeding device 500 located on one side of the conveying start end of the conveying device 200, the paper feeding device 500 being used to feed packaging paper to the conveying device 200; and a wrapping device 600 located on one side of the conveying end of the conveying device 200, the wrapping device 600 being used to wrap the packaging paper.

[0051] When packaging profiles, the paper feeding device 500 first feeds the packaging paper from one side of the conveying start of the conveying device 200, so that the packaging paper is laid flat on the conveying device 200. Then, the profile material to be packaged is placed in, and the sinking packaging mechanism uses the packaging paper to package the profile material. After the packaging is completed, the wrapping device 600 wraps the packaging paper. After the packaging is completed, the conveying device 200 sends the whole thing outward. Because the sinking packaging mechanism sinks the profile material so that the packaging paper wraps tightly to both sides of the profile material from bottom to top, the packaging paper wraps the profile material more tightly, thereby improving the packaging quality of the profile material, reducing the overall volume, and facilitating the transportation and movement of the profile material.

[0052] The paper unwinding device 500 is used to unwind the packaging paper; naturally, as... Figure 6 As shown, the paper feeding device 500 includes a unwinding roller 560, an upper feeding roller 570, a lower feeding roller 580, a fixed blade, and a movable blade 590. The upper feeding roller 570 and the lower feeding roller 580 are rotatably connected to the frame 100 in the vertical direction. A motor that drives the lower feeding roller 580 to rotate is provided on the frame 100. The fixed blade is fixedly connected to the frame 100. The movable blade 590 can move closer to or further away from the fixed blade within the frame 100, thereby realizing the cutting of the packaging paper. The cylindrical packaging paper is located outside the unwinding roller 560. After the packaging paper is pulled out, it passes around the guide roller 510, passes through the paper feeding gap, and enters between the upper feed roller 570 and the lower feed roller 580. The upper feed roller 570 can press the packaging paper against the lower feed roller 580, and the lower feed roller 580 rotates to release the packaging paper. It passes between the movable knife 590 and the fixed knife. When it is necessary to cut the packaging paper, the movable knife 590 moves closer to the fixed knife. By the movable knife 590 and the fixed knife intersecting each other, the packaging paper can be cut.

[0053] The paper feeding device 500 is equipped with a paper guide roller 510 and a dotted line knife 520. A paper passage gap is formed between the dotted line knife 520 and the outer side of the paper guide roller 510. The frame 100 is also equipped with a paper pulling device 700 and a positioning gripper 800. The paper pulling device 700 has a paper pulling gripper that can move back and forth along the length direction of the conveying device 200. The positioning gripper 800 is located on one side of the conveying device 200 and can move along the width direction of the conveying device 200. The pallet is located on the other side of the conveying device 200, and a paper folding device 900 is provided on the pallet. The paper folding device 900 has a folding plate 910 that can rotate to move closer to or away from the conveying device 200.

[0054] As a specific structural embodiment of the paper pulling device 700, such as Figure 9 As shown, the paper pulling device 700 includes a paper pulling translation seat 710, which can move back and forth along the length of the conveying device 200 on the frame 100. The paper pulling gripper includes a lower clamping plate 720 and an upper clamping plate 730 disposed on the paper pulling translation seat 710. The upper clamping plate 730 can move downward toward or upward away from the lower clamping plate 720 on the paper pulling translation seat 710. Before pulling the packaging paper, the upper clamping plate 730 is in a state away from the lower clamping plate 720. When the packaging paper is released outward, the paper pulling translation seat 710 moves horizontally toward the paper feeding device 500, so that the packaging paper enters between the upper clamping plate 730 and the lower clamping plate 720. Then, the upper clamping plate 730 moves downward toward the lower clamping plate 720 to clamp the packaging paper. The paper pulling translation seat 710 moves away from the paper feeding device 500, so that the released packaging paper is laid flat on the conveying device 200.

[0055] In practical applications, a paper-pulling translation device is provided on the frame 100, and a paper-pulling translation seat 710 is provided on the paper-pulling translation device. The paper-pulling translation device can drive the paper-pulling translation seat 710 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, and the paper-pulling translation seat 710 is provided on the first paper-pulling lifting drive. The first paper-pulling lifting drive can drive the paper-pulling translation seat 710 to move up and down. A second paper-pulling lifting drive is also provided on the paper-pulling translation seat 710, and an upper clamping plate 730 is provided on the second paper-pulling lifting drive. The second paper-pulling lifting drive can drive the upper clamping plate 730 to move up and down. The paper-pulling translation device includes a paper-pulling frame, a paper-pulling drive motor, a paper-pulling gear, and a paper-pulling rack. The paper-pulling frame is slidably connected to the frame 100. The paper-pulling drive motor is connected to the paper-pulling frame and drives the paper-pulling gear. The paper-pulling rack is connected to the frame 100, and the paper-pulling gear and the paper-pulling rack engage with each other. When the paper-pulling translation seat 710 needs to move, the paper-pulling drive 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 and second paper-pulling lifting drives can be driven by cylinders, electric screws, or hydraulic cylinders.

[0056] The adjusting gripper 800 is mainly used to clamp one side of the packaging paper and then adjust its positioning. In this embodiment, for example... Figure 7 As shown, the adjusting gripper 800 includes an adjusting frame 810 and an adjusting pressure block 820. The adjusting frame 810 can move along the width direction of the conveying device 200. The adjusting frame 810 forms a limiting concave angle 811 at the position directly opposite the conveying device 200. The adjusting pressure block 820 is disposed on the adjusting frame 810 and can move up and down within the limiting concave angle 811. When the packaging paper is laid on the conveying device 200, one side of the packaging paper is located within the limiting concave angle 811. The limiting concave angle 811 pre-positions one side of the packaging paper. Then, the adjusting pressure block 820 moves downward to press and position the packaging paper within the limiting concave angle 811. At this time, the adjusting frame 810 can move along the width direction of the conveying device 200 to adjust the position of the dotted line of the folded paper. In this way, the position of the packaging paper can be accurately adjusted along the width direction of the conveying device 200.

[0057] In practical applications, the adjusting frame 810 is slidably connected to the frame 100. A adjusting translation drive component is installed on the frame 100 to move the adjusting frame 810. This drive component can be a pneumatic cylinder, an electric lead screw, or a hydraulic cylinder. Alternatively, a rotatable synchronous belt can be installed on the frame 100 and fixedly connected to the adjusting frame 810. An adjusting drive motor drives the synchronous belt to rotate, thereby moving the adjusting frame 810. An adjusting lifting drive component is installed on the adjusting frame 810, and an adjusting pressure block 820 is mounted on it. This lifting drive component can also be a pneumatic cylinder, an electric lead screw, or a hydraulic cylinder.

[0058] The folding device 900 can be directly equipped with a motor to drive the folding plate 910 to rotate, thereby folding the edges of the packaging paper. To better store the folding plate 910 in the tray when not in use, such as... Figure 5 As shown in this embodiment, Figure 8As shown, the folding device 900 includes a folding frame 920, a guide shaft 930, and a tension spring 940. The folding frame 920 is rotatably connected to the frame 100 on the side near the conveying device 200. An opening is provided on the pallet opposite the folding frame 920. The guide shaft 930 is connected to the frame 100 and located between the folding frame 920 and the conveying device 200. The folding plate 910 has a strip structure, and one end of the folding plate 910 is connected to the folding frame 920 away from the conveying device 200. On one side of the device 200, the other end of the folding plate 910 extends toward the conveying device 200 and passes downward around the guide shaft 930. The tension spring 940 is connected between the bottom end of the folding plate 910 and the frame 100. Naturally, a drive motor is provided in the frame 100. The drive motor is connected to the folding frame 920. The folding frame 920 can rotate toward the conveying device 200 and protrude out of the opening or rotate away from the conveying device 200 and retract into the opening. When the packaging paper is laid on the conveyor 200, the folding plate 910 is in the retracted state. The folding plate 910 itself does not interfere with the movement of the packaging paper along the width direction of the conveyor 200. When it is necessary to fold the packaging paper along the folding dotted line, the folding frame 920 rotates towards the conveyor 200, the folding plate 910 rotates and protrudes out of the opening, and drives the packaging paper to fold along the folding dotted line. The folding plate 910 has a strip structure, and the tension spring 940 can keep the folding plate 910 straight. When the folding plate 910 rotates to abut against the pallet, after the folding plate 910 abuts against the edge of the opening of the pallet, it can rotate further, so that the folding plate 910 can press the packaging paper more tightly against the pallet, 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 conveyor 200 and retracts back into the opening to avoid interfering with the next packaging paper feeding.

[0059] The paper feeding device 500 is used to feed packaging paper to the conveying device 200. Before being fed, the packaging paper passes through the paper passage gap formed by the guide roller 510 and the dotted line knife 520. The dotted line knife 520 forms folded lines on the packaging paper. After being fed, the packaging paper is clamped by the paper pulling gripper and pulled along the length of the conveying device 200, so that the packaging paper is laid on the conveying device 200 after being fed. Then, the adjusting gripper 800 clamps one side of the packaging paper, causing the packaging paper to move along the width of the conveying device 200, so that the packaging paper... The folded dotted line formed on the paper is close to the folding plate 910. Then, the folding plate 910 rotates towards the adjusting gripper 800, folding the packaging paper 180 degrees along the folded dotted line. By folding the edges of the packaging paper, the width of the packaging paper is shortened, thereby adjusting the size of the packaging paper. Then, the material to be packaged is placed on the packaging paper for packaging. This can effectively reduce the phenomenon of wrinkles that easily occur when wrapping the packaging paper on the material. The packaging paper after adjusting the size is more compact and beautiful when packaging materials, thus improving the packaging quality.

[0060] The paper feeding device 500 is used to unwind the packaging paper. Naturally, the paper feeding device 500 includes an unwinding roller 560, an upper feeding roller 570, a lower feeding roller 580, a fixed blade, and a movable blade 590. The upper feeding roller 570 and the lower feeding roller 580 are rotatably connected to the frame 100 in the vertical direction. A motor that drives the lower feeding roller 580 to rotate is provided on the frame 100. The fixed blade is fixedly connected to the frame 100. The movable blade 590 can move closer to or further away from the fixed blade within the frame 100, thereby realizing the slitting of the packaging paper. The cylindrical packaging paper is located outside the unwinding roller 560. After the packaging paper is pulled out, it passes around the guide roller 510, passes through the paper feeding gap, and enters between the upper feed roller 570 and the lower feed roller 580. The upper feed roller 570 can press the packaging paper against the lower feed roller 580, and the lower feed roller 580 rotates to release the packaging paper. It passes between the movable knife 590 and the fixed knife. When it is necessary to cut the packaging paper, the movable knife 590 moves closer to the fixed knife. By the movable knife 590 and the fixed knife intersecting each other, the packaging paper can be cut.

[0061] The dotted line cutter 520 is a circular blade with raised cutting edges on the outer side to form dotted lines, such as serrations, on the packaging paper. The dotted line cutter 520 can be directly rotatably connected to the frame 100. In this case, the size of the paper passage gap formed between the dotted line cutter 520 and the guide roller 510 is fixed. In order to facilitate the initial feeding of packaging paper into the paper passage gap, in this embodiment, the paper feeding device 500 includes a first lifting drive 530 and a lifting seat 540. The first lifting drive 530 is disposed on the frame 100, and the lifting seat 540 is disposed on the first lifting drive 530. The first lifting drive 530 can be driven by a cylinder, electric screw, or hydraulic cylinder. The first lifting drive 530 can drive the lifting seat 540 to move downward toward or upward away from the guide roller 510. The dotted line cutter 520 is rotatably connected to the lifting seat 540. Before the packaging paper needs to be fed into the paper feed gap, the first lifting drive 530 can drive the lifting seat 540 upward away from the guide roller 510. At this time, the paper feed gap increases, making it easier to feed the packaging paper in. When the packaging paper needs to be fed outward, the first lifting drive 530 drives the lifting seat 540 downward and close to the guide roller 510, and the paper feed gap decreases. At this time, the dotted line knife 520 presses the packaging paper against the outside of the guide roller 510. As the packaging paper moves, the dotted line knife 520 is driven to rotate and forms a folded dotted line on the packaging paper.

[0062] Depending on the required size of the packaging paper, the position for folding the edges will vary. To facilitate adjustment of the position of the dotted line cutter 520, in this embodiment, the paper feeding device 500 further includes an adjusting screw 550 disposed between the frame 100 and the first lifting drive member 530. The adjusting screw 550 can be a hand-cranked screw or an electrically adjustable screw 550. The adjusting screw 550 can drive the first lifting drive member 530 to move along the width direction of the conveying device 200. Depending on the required size of the packaging paper, the position of the dotted line cutter 520 can be adjusted along the width direction of the conveying device 200 by adjusting the adjusting screw 550. This creates folding dotted lines at corresponding positions on the packaging paper, resulting in different folding widths when the packaging paper is folded, better adapting to different usage needs.
