Description

Technical Field

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

[0002] When strip materials such as profiles are packaged before leaving the factory, they need to be arranged and stacked into a bundle first, and then wrapping paper is wrapped around the outside of the bundle of strip materials to wrap the profiles. When wrapping the outside of the bundle of strip materials with wrapping paper, the bundle of strip materials is usually placed on the flat wrapping paper, and then the two sides of the wrapping paper are folded toward the material by flipping the folding plate, etc., to complete the wrapping of the material with the wrapping paper. In this packaging method, the tightness of the wrapping paper on the material is poor, the material in the wrapping paper is easy to be scattered during transportation and movement, and the volume of the entire package is difficult to reduce. Therefore, there is an urgent need for a device that can better package the material. Summary of the invention

[0003] The object of the present invention is to provide a sinking 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 choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is: A sinking packaging mechanism comprises: a frame; a conveying device, which is movably connected to the frame along the up and down directions, and a lifting device is arranged between the conveying device and the frame, and the lifting device can drive the conveying device to move up and down; a material clamping and folding paper device, including 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, and 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; a material pressing device, which is arranged at a position above the conveying device in the frame, and the material pressing device has a pressure head that can move up and down.

[0005] This technical solution has at least the following beneficial effects: in the initial state, the conveying device is in a state of moving upward to the top of the stroke in the frame. At this time, the packaging paper is first spread on the conveying device, and the material to be packaged is also placed on the packaging paper. The conveying device supports the material, and then the relative position of the first clamping plate and the second clamping plate is adjusted. By bringing the first clamping plate and the second clamping plate closer together, the space formed by the two is reduced to adapt to the width of smaller materials, or by moving the first clamping plate and the second clamping plate farther apart, the space formed by the two is expanded to adapt to 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 downward on the material to ensure that the material and the packaging paper move downward as a whole. In this process, the packaging paper is located on both sides of the material and is pressed by the first clamping plate and the second clamping plate. The first folding paper and the second folding paper are moved toward the material to realize the folding of the wrapping paper, and the wrapping paper is folded from bottom to top to tightly adhere to the surface of the object, and then the first folding paper board and the second folding paper board are moved closer to each other, and the part of the wrapping paper protruding from the top surface of the material is horizontally bent, so that the wrapping paper covers the top surface of the material to realize the wrapping of the material. After completion, the first folding paper board and the second folding paper board are reset in the direction away from each other, the first clamping plate and the second clamping plate are also reset in the direction away from each other, the conveying device moves up and resets, and then the conveying device sends the material along the conveying direction of the conveying device for subsequent packaging procedures. In this way, the material is sunk so that the wrapping paper wraps the two sides of the material tightly from bottom to top, so that the wrapping paper wraps the material more tightly, thereby improving the material packaging quality, helping to reduce the overall volume, and facilitating the transportation and movement of the material.

[0006] As a further improvement of the above technical solution, the first clamping plate and the second clamping plate are respectively provided with a first flexible layer on the side facing each other, and the bottom side of the first folding paper board and the bottom side of the second folding paper board are respectively provided with a second flexible layer. When the conveying device 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 and the first flexible layer on the second clamping plate are respectively in contact with the packaging paper, pressing the two sides of the packaging paper against the material, and utilizing the flexible deformation of the first flexible layer, the packaging paper can be better pressed against the material, and the phenomenon of material deformation caused by excessive pressure can be prevented. Similarly, when the first folding paper board and the second folding paper board turn over the packaging paper, the second flexible layer on the first folding paper board and the second flexible layer on the second folding paper board are respectively in contact with the packaging paper, pressing the top position of the packaging paper against the material, and utilizing the flexible deformation of the second flexible layer, the packaging paper can be more closely attached to the top side of the material for folding, and the phenomenon of material deformation caused by excessive pressure can be prevented.

[0007] As a further improvement of the above technical solution, the first flexible layer is a first brush, and the second flexible layer is a second brush. The first brush is respectively arranged on the first clamping plate and the second clamping plate as the first flexible layer, and similarly, the second brush is respectively arranged on the bottom side of the first folding paper board and the bottom side of the second folding paper board as the second flexible layer. 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 and the second brush, which can provide effective support for the packaging paper to be pressed against the material, and the first brush 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.

[0008] As a further improvement of the above technical solution, the material pressing device includes a material pressing lifting driving member, which is connected to the pressing head and can drive the pressing head to move up and down. The material pressing lifting driving member is connected to the frame and provides a driving force for the pressing head to move in the up and down direction. When the packaging paper and the material need to move downward, the material pressing lifting driving member drives the pressing head to press against the material to assist the packaging paper and the material to move downward as a whole. After completion, when the packaging paper and the material are moved down to the right position, the material pressing lifting driving member drives the pressing head to move upward and reset.

[0009] As a further improvement of the above technical solution, the lifting device includes a linear drive member and a slide, the slide is slidably connected to the bottom of the frame, a guide plate is connected to the slide, the guide plate has a guide bevel extending upwardly along the length direction of the conveying device, a guide wheel is provided at the bottom of the conveying device, the guide wheel is against the guide bevel, the fixed end of the linear drive member is hinged to the frame, the movable end of the linear drive member is hinged to the slide, and the linear drive member can drive the slide to slide along the length direction of the conveying device. The conveying device is pressed toward the guide plate under the action of gravity, and the contact between the guide wheel and the guide plate is used to support the conveying device. When the guide wheel is located at the top position of the guide bevel, the conveying device is located at the top 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 material, the linear drive component drives the slide to slide. At this time, the support height of the guide bevel on the guide wheel gradually decreases, causing the conveying device to gradually move downward, thereby realizing the sinking of the packaging paper and materials. When the conveying device needs to be raised again, the linear drive component drives the slide to slide in the opposite direction. At this time, the support height of the guide bevel on the guide wheel gradually increases, causing the conveying device to move up and reset, thereby realizing the stable up and down movement of the conveying device.

[0010] As a further improvement of the above technical solution, the first clamping plate is fixed to the frame, the clamping origami device includes a first mobile frame, a first motor, a first transmission shaft, a first gear and a first rack, the first mobile frame is slidably connected to the frame in the direction of approaching or moving away from the conveying device, the second clamping plate is connected to the first mobile frame, the first transmission shaft is rotatably connected to the frame, the first motor is driven to connect the first transmission shaft, the first gear is synchronously connected to the first transmission shaft, the first rack is connected to the first mobile frame, and the first rack and the first gear are meshed with each other. The first clamping plate is fixed to the frame, when the first clamping plate and the second clamping plate need to be moved closer to or farther from each other, it depends on the movement of the second clamping plate. Specifically, the first motor drives the first transmission shaft to rotate, so that the first gear on the first transmission shaft rotates synchronously. Since the first gear and the first rack are meshed with each other, the first rack can provide a driving force to approach or move away from the conveying device, so that the second clamping plate is close to or away from the first clamping plate, so that the distance between the first clamping plate and the second clamping plate can be stably and accurately controlled to adapt to different material sizes.

[0011] As a further improvement of the above technical solution, the material clamping origami device includes a second motor, a second transmission shaft, a second gear and a second rack, the first origami paper is connected to the frame in a sliding manner in a direction close to or away from the conveying device, the second transmission shaft is rotatably connected to the frame, the second gear is synchronously connected to the second transmission shaft, the second rack is connected to the first origami paper, and the second rack and the second gear are meshed with each other. When the first origami paper slides in a direction close to the conveying device, the packaging paper can be folded, and when the first origami paper slides in a direction away from the conveying device, it is reset after folding the paper. Specifically, the second motor drives the second transmission shaft to rotate, so that the second gear on the second transmission shaft rotates synchronously. Since the second gear and the second rack are meshed with each other, the second rack can be provided with a driving force in a direction close to or away from the conveying device, so that the first origami paper is close to or away from the conveying device. In this way, the distance that the first origami paper needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0012] As a further improvement of the above technical solution, the clamping origami device includes a third motor, a third transmission shaft, a third gear and a third rack. The second origami paper is connected to the frame in a sliding manner 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 second origami paper, and the third rack and the third gear are meshed with each other. When the second origami paper slides in a direction close to the conveying device, the packaging paper can be folded. When the second origami paper slides in a direction away from the conveying device, the paper is reset after folding. Specifically, the third motor drives the third transmission shaft to rotate, so that the third gear on the third transmission shaft rotates synchronously. Since the third gear and the third rack are meshed with each other, the third rack can be provided with a driving force in a direction close to or away from the conveying device, so that the second origami paper is close to or away from the conveying device. In this way, the distance that the second origami paper needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0013] As a further improvement of the above technical solution, the first folding paper board and the second folding paper board are staggered in the vertical direction. When the first folding paper board and the second folding paper board fold the packaging paper, the lower one folds the packaging paper on one side first, and then the higher one folds the packaging paper on the other side. By staggering the first folding paper board and the second folding paper board, it is ensured that the packaging paper is folded in place and mutual interference and collision are prevented.

[0014] A profile packaging machine comprises: the above-mentioned sinking packaging mechanism; a paper placing device, located at the conveying starting end side of the conveying device, and used to place packaging paper onto the conveying device; a wrapping device, located at the conveying ending end side of the conveying device, and used to wrap the packaging paper.

[0015] This technical solution has at least the following beneficial effects: when packaging profiles, the paper placing device first inputs the packaging paper from the conveying starting end side of the conveying device so that the packaging paper is spread flat on the conveying device, and then the profile material to be packaged is placed. After the profile material is packaged with the packaging paper by the sinking packaging mechanism, the packaging paper is then wrapped and wrapped by the winding and wrapping device. After the packaging is completed, the conveying device sends the whole outward. Because the sinking packaging mechanism sinks the profile material so that the packaging paper tightly wraps 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, which is beneficial to reducing the overall volume and facilitating the transportation and movement of the profile material.

[0034] Reference Figure 1 A sinking packaging mechanism includes a frame 100, a conveying device 200, a material clamping and folding device and a material pressing device, wherein the conveying device 200 is movably connected to the frame 100 along the up and down direction, and a lifting device is arranged 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 material clamping and folding device includes a first material clamping plate 311, a second material clamping plate 331, a first folding paper board 321, and a second folding paper board 341 located on both sides of the conveying device 200, The first clamping plate 311 and the second clamping plate 331 can approach or move away from each other, the first folding paper board 321 is located above the first clamping plate 311, and the second folding paper board 341 is located above the second clamping plate 331. When the conveying device 200 moves downward, the first folding paper board 321 and the second folding paper board 341 can approach or move away from each other; the pressing device is arranged in the frame 100 at a position above the conveying device 200, and the pressing device has a pressing head 420 that can move up and down.

[0035] As can be seen from the above, in the initial state, the conveying device 200 is located in the frame 100 and is in a state of moving upward to the top of the stroke. At this time, the wrapping paper is first spread on the conveying device 200, and the material to be packaged is also placed on the wrapping paper, and the conveying device 200 supports the material. The width of the wrapping paper is generally not less than the cross-sectional outer perimeter of the required packaging material. For example, if the cross-sectional outer perimeter of the required packaging material is 1 meter, 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, and then the relative position of the first clamping plate 311 and the second clamping plate 331 is adjusted, by relatively bringing the first clamping plate 311 and the second clamping plate 331 closer together, reducing the space formed by the two to adapt to the width of the smaller material, or by The first and second folding plates 321 and 341 are relatively far apart, and the space formed by the two is expanded to accommodate the width of the larger material. Then the lifting device drives the conveying device 200 to move downward, and the pressure head 420 in the pressing device presses downward on the material to ensure that the material and the packaging paper move downward as a whole. In this process, the packaging paper is located on both sides of the material and is pressed against the material by the first clamping plate 311 and the second clamping plate 331 to achieve the folding of the packaging paper, and make the packaging paper close to the surface of the object from bottom to top and folded. Then the first folding paper board 321 and the second folding paper board 341 are brought close to each other, and the part of the packaging paper protruding from the top surface of the material is horizontally bent so that the packaging paper covers the top surface of the material to achieve the wrapping of the material. After completion, the first folding paper board 321 and the second folding paper board 341 are reset in the direction away from each other, the first clamping plate 311 and the second clamping plate 331 are also reset in the direction away from each other, the conveying device 200 moves up and resets, and then the conveying device 200 sends the material along the conveying direction of the conveying device 200 for subsequent packaging processes. 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.

[0036] 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 311 and the second clamping plate 331 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 311 and the second clamping plate 331 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 311 and the second clamping plate 331 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 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, and the first clamping plate 311 and the second clamping plate 331 will not interfere with the conveying roller when they are close to each other, thereby better improving the overall applicability.

[0037] In the above embodiment, the wrapping 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 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 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 board 321 and the bottom side of the second folding paper board 341 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 311 and the first flexible layer on the second clamping plate 331 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 better press the packaging paper against the material and prevent the material from being deformed due to excessive pressure. Similarly, when the first folding paper board 321 and the second folding paper board 341 turn over the packaging paper, the second flexible layer on the first folding paper board 321 and the second flexible layer on the second folding paper board 341 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 make the packaging paper closer to the top side of the material for folding and prevent the material from being deformed due to excessive pressure.

[0038] 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 3 and Figure 4 As shown, the first flexible layer is the first brush 332, that is, the first brush 332 is respectively arranged on the side of the first clamping plate 311 and the second clamping plate 331 facing each other, and the second flexible layer is the second brush 342, that is, the second brush 342 is respectively arranged on the bottom side of the first folding paper board 321 and the bottom side of the second folding paper board 341. The first brush 332 is respectively arranged on the first clamping plate 311 and the second clamping plate 331 as the first flexible layer, and similarly, the second brush 342 is respectively arranged on the bottom side of the first folding paper board 321 and the bottom side of the second folding paper board 341 as the second flexible layer. When the packaging paper is folded closely to the outside of the material, the packaging paper is pressed against the outside of the material by the first brush 332 and the second brush 342, which can provide effective support for the packaging paper to be pressed against the material, and the first brush 332 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.

[0039] 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.12As 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 length direction of the conveying device 200, the bottom of the conveying device 200 is provided with a guide wheel 220, 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.

[0040] There are many ways for the first clamping plate 311 and the second clamping plate 331 to move closer to or farther from each other. For example, the first clamping plate 311 and the second clamping plate 331 can both move in the frame 100, or one of the first clamping plate 311 and the second clamping plate 331 is fixed in the frame 100, and the other can move in the frame 100. In this embodiment, the first clamping plate 311 is fixed to the frame 100, and the clamping origami device includes a first moving frame 333, a first motor, a first transmission shaft 334, a first gear 335 and a first rack 336, the first movable frame 333 is slidably connected to the frame 100 along the direction of approaching or moving away from the conveying device 200, the second clamping plate 331 is connected to the first movable frame 333, the first transmission shaft 334 is rotatably connected to the frame 100, the first motor drives the first transmission shaft 334, the first gear 335 is synchronously connected to the first transmission shaft 334, the first rack 336 is connected to the first movable frame 333, and the first rack 336 and the first gear 335 are meshed with each other. The first clamping plate 311 is fixed on the frame 100. When the first clamping plate 311 and the second clamping plate 331 need to be moved closer to or further away from each other, the second clamping plate 331 is relied upon to be moved. Specifically, the first motor drives the first transmission shaft 334 to rotate, so that the first gear 335 on the first transmission shaft 334 rotates synchronously. Since the first gear 335 and the first rack 336 are meshed with each other, the first rack 336 can be provided with a driving force to move closer to or away from the conveying device 200, thereby making the second clamping plate 331 closer to 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.

[0041] 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 311 and second clamping plates 331 can be arranged at intervals along the length direction of the conveying device 200, and the positions of the multiple first clamping plates 311 and the multiple second clamping plates 331 correspond to each other. At this time, for the transmission of the multiple second clamping plates 331, multiple first mobile frames 333 can be arranged at corresponding positions in the frame 100, and the multiple second clamping plates 331 are respectively connected to the multiple first mobile frames 333, and the first motor drives the multiple first gears 335 to rotate through the first transmission shaft 334, and the multiple first gears 335 are respectively engaged with the multiple first racks 336, thereby driving the multiple second clamping plates 331 to move in translation at the same time.

[0042] The material-clamping origami device has a driving source that can drive the first origami paper 321 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 321 is directly driven by such a driving source, thereby driving the first origami paper 321 to move translationally. In this embodiment, the material-clamping origami device includes a second motor, a second transmission shaft 322, a second gear 323 and a second rack 324. The first origami paper 321 is slidably connected to the frame 100 in a direction approaching or moving 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 origami paper 321, and the second rack 324 and the second gear 323 are meshed with each other. When the first folding paper board 321 slides in the direction approaching the conveying device 200, the packaging paper can be folded. When the first folding paper board 321 slides in the direction away from the conveying device 200, it is reset after folding the paper. Specifically, the second motor drives the second transmission shaft 322 to rotate, so that the second gear 323 on the second transmission shaft 322 rotates synchronously. Since the second gear 323 and the second rack 324 are meshed with each other, the second rack 324 can be provided with a driving force to move closer to or away from the conveying device 200, so that the first folding paper board 321 is close to or away from the conveying device 200. In this way, the distance that the first folding paper board 321 needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0043] Similarly, the material-clamping origami device has a driving source that can drive the second origami paper 341 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 341 is directly driven by such a driving source, thereby driving the second origami paper 341 to move translationally. In this embodiment, the material-clamping origami device includes a third motor, a third transmission shaft 343, a third gear 345 and a third rack 346. The second origami paper 341 is slidably connected to the frame 100 in a direction approaching or moving away from the conveying device 200. The third transmission shaft 343 is rotatably connected to the frame 100. The third gear 345 is synchronously connected to the third transmission shaft 343. The third rack 346 is connected to the second origami paper 341. The third rack 346 and the third gear 345 are meshed with each other. When the second folding paper board 341 slides in the direction approaching the conveying device 200, the packaging paper can be folded. When the second folding paper board 341 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 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 are engaged with each other, the third rack 346 can be provided with a driving force to move closer to or away from the conveying device 200, so that the second folding paper board 341 is close to or away from the conveying device 200. In this way, the distance that the second folding paper board 341 needs to move when folding the packaging paper can be stably and accurately controlled to adapt to different material sizes.

[0044] 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 321 and second folding paper boards 341 can be arranged at intervals along the length direction of the conveying device 200, and the positions of the multiple first folding paper boards 321 and the multiple second folding paper boards 341 correspond to each other. At this time, for the movement of the multiple first folding paper boards 321 and the second folding paper boards 341, second racks 324 can be respectively arranged on the multiple first folding paper boards 321, and third racks 346 can be respectively arranged on the multiple second folding paper boards 341. Correspondingly, the positions of the second transmission shaft 322 corresponding to the multiple second racks 324 are synchronously connected with second gears 323, and the multiple second gears 323 and the multiple second racks 324 are respectively meshed with each other. The positions of the third transmission shaft 343 corresponding to the multiple third racks 346 are synchronously connected with third gears 345, and the multiple third gears 345 and the multiple third racks 346 are respectively meshed with each other, thereby driving the multiple first folding paper boards 321 and the multiple second folding paper boards 341 to move in translation at the same time.

[0045] The first folding paper board 321 and the second folding paper board 341 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 first folding paper board 321 and the second folding paper board approaching each other have a travel end that tends to abut each other. The first folding paper board 321 and the second folding paper 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 paper board 321 and the second folding paper board 341 from colliding with each other, in this embodiment, the first folding paper board 321 and the second folding paper board 341 are staggered with each other in the up and down directions. Naturally, the lengths of the second brush 342 on the bottom side of the first folding paper board 321 and the second brush 342 on the bottom side of the second folding paper board 341 should be able to meet the requirements for folding the packaging paper. For example, the bottom end of the second brush 342 on the bottom side of the first folding paper board 321 and the bottom end of the second brush 342 on the bottom side of the second folding paper board 341 are located on the same horizontal plane. When the first folding paper board 321 and the second folding paper board 341 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 321 completes the folding of one side of the wrapping paper, the higher second folding paper board 341 folds the other side of the wrapping paper. By using the upper and lower staggered avoidance of the first folding paper board 321 and the second folding paper board 341, it can be ensured that the folding of the wrapping paper is in place and prevent mutual interference and collision. In practical applications, in order to better lay the wrapping paper flat, a support plate can be provided above the lower folding paper board in the frame 100. For example, when the height of the first folding paper board 321 is lower than that of the second folding paper board 341, a support plate can be provided above the first folding paper board 321 in the frame 100. The support plate and the second folding paper board 341 are flush with each other. At this time, the wrapping paper can be better laid flat on the second folding paper board 341 and the support plate.

[0046] The pressing device has a driving source that can drive the pressing head 420 to move up and down. Specifically, the pressing device includes a pressing lifting driving member 410, which is connected to the pressing head 420. The pressing lifting driving member 410 can drive the pressing head 420 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 410 is connected to the frame 100 to provide a driving force for the pressing head 420 to move in the up and down direction. When the packaging paper and the material need to move down, the pressing lifting driving member 410 drives the pressing head 420 to press against the material to assist the packaging paper and the material to move down as a whole. After completion, when it moves down to the right position, the pressing lifting driving member 410 drives the pressing head 420 to move up and reset.

[0047] like Figure 5 , Fig.10 , Fig.11 and Fig.12As shown, a profile packaging machine includes: the above-mentioned sinking packaging mechanism; a paper placing device 500, located at the conveying starting end side of the conveying device 200, and the paper placing device 500 is used to release packaging paper to the conveying device 200; a winding and wrapping device 600, located at the conveying end side of the conveying device 200, and the winding and wrapping device 600 is used to wind and wrap the packaging paper.

[0048] When packaging the profile, the paper placing device 500 first inputs the packaging paper from the conveying starting end side of the conveying device 200 so that the packaging paper is spread flat on the conveying device 200, and then the profile material to be packaged is placed. After the profile material is packaged with the packaging paper by the sinking packaging mechanism, the packaging paper is then wrapped and wrapped by the winding and wrapping device 600. After the packaging is completed, the conveying device 200 sends the whole outward. Since the sinking packaging mechanism sinks the profile material so that the packaging paper tightly wraps 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, which is beneficial to reducing the overall volume and facilitating the transportation and movement of the profile material.

[0049] The paper placing device 500 is provided with a paper guide roller 510 and a dotted line knife 520, and a paper passing gap is formed between the dotted line knife 520 and the outer side of the paper guide roller 510. The frame 100 is also provided with a paper pulling device 700 and a position adjusting clamp 800. The paper pulling device 700 has a paper pulling clamp that can move back and forth along the length direction of the conveying device 200; the position adjusting clamp 800 is located on one side of the conveying device 200, and the position adjusting clamp 800 can move along the width direction of the conveying device 200; the support plate is located on the other side of the conveying device 200, and a folding device 900 is provided on the support plate, and the folding device 900 has a folding plate 910 that can be rotated close to or away from the conveying device 200.

[0050] The paper placing device 500 is used to place the wrapping paper on a roll. Figure 6As shown, the paper feeding device 500 also includes a unwinding roller 560, an upper paper feeding roller 570, a lower paper feeding roller 580, a fixed knife and a movable knife 590. The upper paper feeding roller 570 and the lower paper feeding roller 580 are connected to the frame 100 in a rotatable manner along the up and down directions. A motor is provided on the frame 100 to drive the lower paper feeding roller 580 to rotate. The fixed knife is fixedly connected to the frame 100, and the movable knife 590 can be close to or away from the fixed knife in the frame 100, thereby realizing the cutting of the packaging paper. The cylindrical wrapping paper is located outside the unwinding roller 560. After being pulled out, the wrapping paper bypasses the paper guide roller 510, passes through the paper gap, and enters between the upper paper feed roller 570 and the lower paper feed roller 580. The upper paper feed roller 570 can press the wrapping paper against the lower paper feed roller 580, and the lower paper feed roller 580 rotates to release the wrapping paper and pass between the movable knife 590 and the fixed knife. When the wrapping paper needs to be cut, the movable knife 590 approaches the fixed knife, and the movable knife 590 and the fixed knife are interlaced with each other to achieve the cutting of the wrapping paper.

[0051] As a specific structural embodiment of the paper pulling device 700, Fig. 9 As shown, the paper pulling device 700 includes a paper pulling translation seat 710, and the paper pulling translation seat 710 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 720 and an upper clamping plate 730 arranged on the paper pulling translation seat 710, and 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 the packaging paper is pulled and conveyed, 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 placing device 500, so that the packaging paper enters between the upper clamping plate 730 and the lower clamping plate 720, and then the upper clamping plate 730 moves downward toward the lower clamping plate 720 to clamp the packaging paper, and the paper pulling translation seat 710 moves in a direction away from the paper placing device 500, so that the released packaging paper is flatly laid on the conveying device 200.

[0052] In actual application, a paper pulling translation device is arranged on the frame 100, and the paper pulling translation seat 710 is arranged 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 component, and the paper pulling translation seat 710 is arranged on the first paper pulling lifting drive component. The first paper pulling lifting drive component can drive the paper pulling translation seat 710 to move up and down. The paper pulling translation seat 710 is also provided with a second paper pulling lifting drive component, and the upper clamping plate 730 is arranged on the second paper pulling lifting drive component. The second paper pulling lifting drive component 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 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 710 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.

[0053] The positioning gripper 800 is mainly used to adjust the position after clamping one side of the packaging paper. In this embodiment, Figure 7 As shown, the positioning clamp 800 includes a positioning frame 810 and a positioning pressure block 820. The positioning frame 810 can move along the width direction of the conveying device 200. The positioning frame 810 forms a limited concave angle 811 at the position opposite to the conveying device 200. The positioning pressure block 820 is arranged on the positioning frame 810. The positioning pressure block 820 can move up and down in the limited concave angle 811. When the wrapping paper is laid on the conveying device 200, one side of the wrapping paper is located in the limited concave angle 811. The limited concave angle 811 pre-positions one side of the wrapping paper. Then, the positioning pressure block 820 moves downward to press the wrapping paper tightly and position it in the limited concave angle 811. At this time, the positioning frame 810 can move along the width direction of 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.

[0054] In practical applications, the positioning frame 810 is slidably connected to the frame 100, and a positioning translation driving member for driving the positioning frame 810 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 810, and the synchronous belt is driven to rotate by the positioning driving motor, thereby driving the positioning frame 810 to move. A positioning lifting driving member is provided on the positioning frame 810, and the positioning pressure block 820 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.

[0055] The folding device 900 may be directly provided with a motor for driving the folding plate 910 to rotate, so as to realize the folding of the packaging paper. In order to better store the folding plate 910 in the support plate when it is not needed, Figure 5 As shown, in this embodiment, Figure 8As shown, the folding device 900 includes a paper folding frame 920, a guide shaft 930 and a tension spring 940. The paper folding frame 920 is rotatably connected to the frame 100 at a side close to the conveying device 200. A hole is provided on the support plate facing the paper folding frame 920. The guide shaft 930 is connected to the frame 100 and is located between the paper folding frame 920 and the conveying device 200. The folding plate 910 is a belt-shaped structure. One end of the folding plate 910 is connected to the paper 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 direction close to the conveying device 200 and downwardly bypasses the guide shaft 930, and the tension spring 940 is connected between the bottom end of the folding plate 910 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 920. The origami frame 920 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 910 is in a state of being retracted into the hole, and the folding plate 910 itself will 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 origami imaginary line, the folding frame 920 rotates in the direction close to the conveying device 200, and the folding plate 910 rotates to protrude out of the hole and drives the wrapping paper to be folded along the origami imaginary line position. The folding plate 910 is a belt-shaped structure, and the tension spring 940 can keep the folding plate 910 straightened. When the folding plate 910 rotates to abut against the support plate, after the folding plate 910 abuts against the edge of the hole of the support plate, it can be further rotated so that the folding plate 910 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 200 and is re-entered into the hole to avoid interference with the next wrapping paper feeding.

[0056] The paper placing device 500 is used to place the wrapping paper onto the conveying device 200. Before being placed, the wrapping paper passes through the paper gap formed by the paper guide roller 510 and the dotted line knife 520. The dotted line knife 520 forms a folded paper dotted line on the wrapping paper. After the wrapping paper is placed, 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 placed. Then, the positioning clamp 800 clamps one side of the wrapping paper, driving the wrapping paper to move along the width direction of the conveying device 200, so that the wrapping paper can be placed on the conveying device 200. The dotted line of folding paper formed on the paper is close to the folding plate 910, and then the folding plate 910 rotates toward the direction of the adjusting clamp 800 to fold the packaging paper 180 degrees along the dotted line of folding paper. In this way, the width of the packaging paper is shortened by folding the edge 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 of wrinkles when wrapping the packaging paper 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 packaging quality.

[0057] The paper placing device 500 is used for unwinding the wrapping paper. Naturally, the paper placing device 500 includes an unwinding roller 560, an upper paper feeding roller 570, a lower paper feeding roller 580, a fixed knife and a movable knife 590. The upper paper feeding roller 570 and the lower paper feeding roller 580 are connected to the frame 100 for rotation along the up and down directions. A motor for driving the lower paper feeding roller 580 to rotate is arranged on the frame 100. The fixed knife is fixedly connected to the frame 100, and the movable knife 590 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 560. After being pulled out, the wrapping paper bypasses the paper guide roller 510, passes through the paper gap, and enters between the upper paper feed roller 570 and the lower paper feed roller 580. The upper paper feed roller 570 can press the wrapping paper against the lower paper feed roller 580, and the lower paper feed roller 580 rotates to release the wrapping paper and pass between the movable knife 590 and the fixed knife. When the wrapping paper needs to be cut, the movable knife 590 approaches the fixed knife, and the movable knife 590 and the fixed knife are interlaced with each other to achieve the cutting of the wrapping paper.

[0058] The dotted line knife 520 is a circular blade, and a raised blade edge is provided on the outer side of the blade for forming dotted lines, such as saw teeth, on the packaging paper. The dotted line knife 520 can be directly rotatably connected to the frame 100. At this time, the size of the paper feeding gap formed by the dotted line knife 520 and the paper guide roller 510 is fixed. In order to facilitate the feeding of packaging paper into the paper feeding gap at the beginning, in this embodiment, the paper placing device 500 includes a first lifting drive member 530 and a lifting seat 540. The first lifting drive member 530 is arranged on the frame 100, and the lifting seat 540 is arranged on the first lifting drive member 530. The first lifting drive member 530 can adopt a driving source such as a cylinder, an electric screw or a hydraulic cylinder. The first lifting drive member 530 can drive the lifting seat 540 to move downward toward or upward away from the paper guide roller 510, and the dotted line knife 520 is rotatably connected to the lifting seat 540. When it is necessary to feed the packaging paper into the paper feeding gap, the first lifting drive member 530 can drive the lifting seat 540 to move upward away from the paper guide roller 510. 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 530 drives the lifting seat 540 to move downward close to the paper guide roller 510, and the paper feeding gap is reduced. At this time, the dotted line knife 520 presses the packaging paper against the outside of the paper guide roller 510. As the packaging paper moves, the dotted line knife 520 is driven to rotate and forms a paper folding dotted line on the packaging paper.

[0059] 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 520, in this embodiment, the paper placing device 500 also includes an adjusting screw rod 550 disposed between the frame 100 and the first lifting drive member 530. The adjusting screw rod 550 can be a hand-cranked screw rod or an electric adjusting screw rod 550. The adjusting screw rod 550 can drive the first lifting drive member 530 to move along the width direction of the conveying device 200. According to the required size of the wrapping paper, the position of the dotted line knife 520 can be adjusted along the width direction of the conveying device 200 by adjusting the screw rod 550, 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.
