Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding machine technology, and in particular to a winding mechanism for packaging color boxes after UV printing. Background Technology
[0002] After UV printing, packaging boxes often require the use of a winding machine during storage and transportation. The winding machine bundles and winds up the stacked packaging boxes to prevent them from scattering due to loose stacking during handling and storage, while also keeping the stacked packaging boxes neat and aesthetically pleasing.
[0003] Existing packaging box winding machines typically involve placing stacked packaging boxes on the machine's worktable, positioning the stacked boxes in the center of a recessed column, and then using an internal conveying mechanism to eject strapping through holes in the recessed column and worktable, wrapping it around the stacked packaging boxes. An internal tightening mechanism then pulls and tightens the strapping. A heating element extends to the two ends of the strapping, heating them to fuse and fix them in place. Finally, a cutter extends from inside the machine to cut the strapping, thus completing the packaging box winding process.
[0004] However, since multiple packaging boxes are relatively loose when stacked together, gaps may appear between the boxes after the strapping is rolled up. This results in less resistance between the boxes and causes them to slide or fall during movement, affecting the stability of the packaging box roll-up. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a packaging box winding mechanism after UV printing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a packaging color box winding mechanism after UV printing, comprising a machine body, a recessed post on one side of the machine body, a controller on one side of the machine body, a wire feeding shaft on one side of the machine body, a feeding pipe on one side of the machine body, wire holes on one side of both the machine body and the recessed post, a pressing device on one side of the recessed post for pressing and aligning the edges of multiple stacked packaging color boxes, and an anti-accidental touch device on one side of the controller to prevent personnel from accidentally touching the buttons on the controller.
[0007] The effect achieved by the above components is as follows: First, the stacked packaging boxes are placed on the worktable of the machine body, so that the stacked packaging boxes are positioned in the middle of the concave column. Then, the strapping tape on the feed spool is drawn into the machine body through the feed pipe by the conveying mechanism inside the machine body. Then, the strapping tape is ejected through the wire holes on the concave column and the worktable by the conveying mechanism inside the machine body and wrapped around the stacked packaging boxes. At the same time, the strapping tape is pulled and tightened by the tightening mechanism inside the machine body. Then, the heating plate inside the machine body extends to the intersection of the two ends of the strapping tape to heat it, so that the two ends of the strapping tape are thermally fused and fixed together. Finally, the cutter inside the machine body pushes out to cut the strapping tape, thus achieving the winding process of the packaging boxes.
[0008] Preferably, the clamping device includes a concave frame, which is fixedly connected to a concave column. A toothed rod is provided inside the concave frame. A motor is fixedly connected to one side of the concave frame, and a gear is fixedly connected to the output end of the motor. The gear is located inside the toothed rod and meshes with it. A perforated plate is fixedly connected to one end of the toothed rod. Two rectangular slots are symmetrically formed on one side of the perforated plate. Electric telescopic rods are fixedly connected to the inner walls of both rectangular slots. Slider blocks are fixedly connected to the output ends of both electric telescopic rods. Two clamping plates are symmetrically slidably connected to the inner walls of the perforated plate. The surfaces of the two sliders are slidably connected to the inner walls of the two clamping plates. A first spring is fixedly connected to one side of each of the two clamping plates. A concave plate is fixedly connected to the other end of each of the two first springs. The inner walls of the two concave plates are slidably connected to the surface of the perforated plate.
[0009] The effect achieved by the above components is as follows: By setting up a clamping device, multiple stacked packaging boxes are first placed on the worktable of the machine body and positioned in the middle of the concave column, so that the multiple packaging boxes are located below the perforated plate. At this time, the motor is started, causing the motor to drive the gear to rotate. Under the meshing action of the gear and the rack, the gear drives the rack to move closer to the machine body, causing the rack to move the perforated plate closer to the machine body, causing the perforated plate to move the two clamping plates closer to the machine body. When the perforated plate moves to a position close to the surface of the top layer of packaging boxes, the surfaces of the two clamping plates are made to fit against the surface of the machine body, allowing the two clamping plates to move up and down along the inside of the perforated plate to adapt to the height of the stacked packaging boxes. At the same time, two electric telescopic rods are activated, causing the two electric telescopic rods to drive the two sliders to move in opposite directions, causing the two sliders to pull the clamping plates. The plates move in opposite directions inside the perforated plate, causing the two clamping plates to slide along the surface of the perforated plate, along with the two first springs and the concave plate. When the two clamping plates move in opposite directions to the position where they simultaneously press the surface of the packaging boxes, they press the sides of the stacked packaging boxes and align them. At this time, the motor drives the gear to move the rack, which in turn moves the perforated plate closer to the machine body. When the perforated plate moves to the position where it presses the surface of the packaging boxes, it compacts the stacked packaging boxes, achieving alignment and compression. This reduces the gaps between the packaging boxes after the strapping is wound up due to the loose overall structure of the stacked boxes, which could cause partial sliding or slippage during movement. This improves the winding stability of the packaging boxes.
[0010] Preferably, a guide rod is fixedly connected to one side of each of the two clamping plates, the two guide rods are respectively located inside the two first springs, and the surfaces of the two guide rods are slidably connected to the inner walls of the two concave plates.
[0011] The effect achieved by the above-mentioned components is that by setting the guide rod, the guide rod can be located inside the first spring to provide auxiliary support, thereby reducing the large-scale bending and deformation of the first spring during its extension and retraction, which would affect the normal use of the first spring.
[0012] Preferably, the inner walls of the two concave plates are fixedly connected to limit blocks, and the surface of the perforated plate is symmetrically provided with two limit grooves, and the surfaces of the two limit blocks are slidably connected to the inner walls of the two limit grooves respectively.
[0013] The effect achieved by the above components is as follows: by setting the limiting block and the limiting groove, the limiting block can be located inside the limiting groove to assist in limiting the concave plate, reducing the tilting or shaking of the concave plate during the sliding process. At the same time, in conjunction with the guide rod, the clamping plate can be assisted in limiting the clamping plate, improving the stability of the clamping plate.
[0014] Preferably, a reinforcing block is fixedly connected to the side of the toothed bar near the perforated plate, and the reinforcing block is fixedly connected to the perforated plate.
[0015] The effect achieved by the above components is that by setting up the reinforcing block, the connection between the rack and the perforated plate can be reinforced, thereby improving the connection strength between the rack and the perforated plate and reducing the possibility of the perforated plate separating from the rack during use.
[0016] Preferably, a rubber strip is fixedly connected to one side of the perforated plate, and the surface of the rubber strip is provided with multiple anti-slip protrusions.
[0017] The effect achieved by the above components is that by setting rubber strips, the friction between the perforated plate and the surface of the packaging box is increased, reducing the possibility of the packaging box sliding when the perforated plate squeezes the packaging box.
[0018] Preferably, the anti-accidental touch device includes a guide rail, which is fixedly connected to the side of the controller near the button. A sliding hole is provided on one side of the guide rail. A second spring is provided inside the guide rail. One end of the second spring is fixedly connected to the inner wall of the guide rail. A protective plate is slidably connected to the inner wall of the guide rail. The other end of the second spring is fixedly connected to the protective plate. A positioning post is fixedly connected to one side of the protective plate. The surface of the positioning post is slidably connected to the inner wall of the sliding hole.
[0019] The effect achieved by the above components is as follows: by setting up an anti-accidental touch device, under the reaction force of the second spring, the second spring pushes the protective plate to move along the inside of the guide rail towards the concave post, so that the protective plate drives the positioning post to slide along the inside of the sliding hole. When the positioning post moves to the maximum position along the inside of the sliding hole, the protective plate is located on one side of the controller and completely covers the button on the controller. At the same time, it intercepts external objects and prevents external objects from contacting the button on the controller, thereby achieving the anti-accidental touch treatment of the button on the controller. This reduces the chance that personnel will accidentally touch the button on the controller during operation, causing changes in the machine's operating program and affecting the normal winding of the packaging box.
[0020] Preferably, a handle is fixedly connected to one side of the protective plate, and the inner side of the handle is provided with multiple anti-slip protrusions.
[0021] The effect achieved by the above components is that by setting handles, the handles can provide a point of leverage for personnel, allowing personnel to easily move the protective plate by manually moving the handles.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0023] In this invention, by setting a clamping device, multiple stacked packaging boxes can be aligned and clamped, reducing the overall looseness of multiple packaging boxes after they are stacked together. This prevents gaps from forming between packaging boxes after the strapping is rolled up, which could cause partial sliding or slippage of multiple packaging boxes during movement, thus improving the rolling stability of the packaging boxes.

Detailed Implementation
[0030] Reference Figure 1-5As shown, this embodiment discloses a packaging box winding mechanism after UV printing, including a machine body 1, a recessed post 2 on one side of the machine body 1, a controller 3 on one side of the machine body 1, a wire feeding shaft 4 on one side of the machine body 1, a feed pipe 5 on one side of the machine body 1, wire holes 6 on one side of both the machine body 1 and the recessed post 2, a pressing device 7 on one side of the recessed post 2 for pressing and aligning the edges of multiple stacked packaging boxes, and an anti-accidental contact device 8 on one side of the controller 3 to prevent accidental contact with the buttons on the controller 3. First, the stacked packaging boxes are placed on the worktable of the machine body 1, so that the stacked boxes... The packaging boxes are placed in the middle of the concave column 2. Then, the strapping tape on the feed spool 4 is drawn into the machine body 1 through the feed pipe 5 by the conveying mechanism inside the machine body 1. The strapping tape is then ejected through the concave column 2 and the wire hole 6 on the worktable by the conveying mechanism inside the machine body 1 and wrapped around the stacked packaging boxes. At the same time, the strapping tape is pulled and tightened by the tightening mechanism inside the machine body 1. Then, the heating plate inside the machine body 1 extends to the intersection of the two ends of the strapping tape to heat it, so that the two ends of the strapping tape are thermally fused and fixed together. Then, the cutter inside the machine body 1 pushes out to cut the strapping tape, thus achieving the winding process of the packaging boxes.
[0031] Reference Figure 2 , Figure 3 and Figure 4As shown, this embodiment discloses a clamping device 7 including a concave frame 71, which is fixedly connected to a concave column 2. A toothed rod 72 is provided inside the concave frame 71. A motor 73 is fixedly connected to one side of the concave frame 71. A gear 74 is fixedly connected to the output end of the motor 73. The gear 74 is located inside the toothed rod 72 and meshes with the toothed rod 72. A perforated plate 75 is fixedly connected to one end of the toothed rod 72. Two rectangular slots 76 are symmetrically opened on one side of the perforated plate 75. Electric telescopic rods 710 are fixedly connected to the inner walls of both rectangular slots 76. Slider blocks 711 are fixedly connected to the output ends of both electric telescopic rods 710. Two clamping plates 712 are symmetrically slidably connected to the inner wall of the perforated plate 75. The surfaces of the two sliders 711 respectively contact the two clamping plates 712. The inner walls of the plate 712 are slidably connected. A first spring 713 is fixedly connected to one side of each of the two clamping plates 712. A concave plate 714 is fixedly connected to the other end of each of the two first springs 713. The inner walls of the two concave plates 714 are slidably connected to the surface of the perforated plate 75. By setting a clamping device 7, multiple stacked packaging boxes are first placed on the worktable of the machine body 1 and positioned in the middle of the concave column 2, so that the multiple packaging boxes are located below the perforated plate 75. At this time, the motor 73 is started, causing the motor 73 to drive the gear 74 to rotate. Under the meshing action of the gear 74 and the rack 72, the gear 74 drives the rack 72 to move closer to the machine body 1, causing the rack 72 to drive the perforated plate 75 to move closer to the machine body 1. This causes the perforated plate 75 to move the two clamping plates 712 closer to the machine body 1. When the perforated plate 75 moves to a position close to the surface of the top layer of packaging boxes, the surfaces of the two clamping plates 712 come into contact with the surface of the machine body 1. This allows the two clamping plates 712 to move up and down along the interior of the perforated plate 75 to adapt to the height of the stacked packaging boxes. Simultaneously, two electric telescopic rods 710 are activated, causing the two electric telescopic rods 710 to simultaneously drive the two sliders 711 to move in opposite directions. This causes the two sliders 711 to pull the clamping plates 712 to move in opposite directions along the interior of the perforated plate 75. This causes the two clamping plates 712 to drive the two first springs 713 and the concave plate 714 to slide along the surface of the perforated plate 75. When the two clamping plates 712 move in opposite directions, they simultaneously squeeze the packaging boxes. When the boxes are positioned on the surface, the two clamping plates 712 press and align the two sides of the stacked packaging boxes. At this time, the motor 73 continues to drive the gear 74 to move the rack 72, which in turn moves the perforated plate 75 closer to the machine body 1. When the perforated plate 75 moves to the position of pressing the surface of the packaging boxes, it compacts the stacked packaging boxes, achieving alignment and compression. This reduces the gaps between the packaging boxes after the strapping is wound up due to the loose overall structure of the stacked boxes, which could cause partial slippage or falling during movement. This improves the winding stability of the packaging boxes.
[0032] Reference Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses that guide rods 716 are fixedly connected to one side of each of the two clamping plates 712. The two guide rods 716 are respectively located inside the two first springs 713, and the surfaces of the two guide rods 716 are slidably connected to the inner walls of the two concave plates 714. By setting the guide rods 716, the guide rods 716 can be located inside the first springs 713 to provide auxiliary support, reducing the possibility of large-scale bending and deformation of the first springs 713 during telescopic movement, which would affect the normal use of the first springs 713. Limiting blocks 715 are fixedly connected to the inner walls of the two concave plates 714. Two limiting grooves 77 are symmetrically opened on the surface of the perforated plate 75. The surfaces of the two limiting blocks 715 are slidably connected to the inner walls of the two limiting grooves 77 respectively. By setting the limiting blocks 715 and the limiting grooves 77, the limiting blocks 715 can be located inside the limiting grooves 77 to assist in limiting the concave plates 714, reducing the tilting or shaking of the concave plates 714 during the sliding process. At the same time, the guide rod 716 can assist in limiting the clamping plate 712, improving the stability of the clamping plate 712.
[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses that a reinforcing block 79 is fixedly connected to the side of the toothed rod 72 near the perforated plate 75. The reinforcing block 79 is fixedly connected to the perforated plate 75. By setting the reinforcing block 79, the connection between the toothed rod 72 and the perforated plate 75 can be reinforced, thereby improving the connection strength between the toothed rod 72 and the perforated plate 75 and reducing the possibility of the perforated plate 75 separating from the toothed rod 72 during use. A rubber strip 78 is fixedly connected to one side of the perforated plate 75. The surface of the rubber strip 78 is provided with multiple anti-slip protrusions. By setting the rubber strip 78, the rubber strip 78 can increase the friction between the perforated plate 75 and the surface of the packaging box, thereby reducing the possibility of the packaging box sliding when the perforated plate 75 squeezes the packaging box.
[0034] Reference Figure 5As shown, this embodiment discloses an anti-accidental touch device 8, including a guide rail 81. The guide rail 81 is fixedly connected to the side of the controller 3 near the button. A sliding hole 82 is provided on one side of the guide rail 81. A second spring 85 is provided inside the guide rail 81. One end of the second spring 85 is fixedly connected to the inner wall of the guide rail 81. A protective plate 83 is slidably connected to the inner wall of the guide rail 81. The other end of the second spring 85 is fixedly connected to the protective plate 83. A positioning post 84 is fixedly connected to one side of the protective plate 83. The surface of the positioning post 84 is slidably connected to the inner wall of the sliding hole 82. By setting the anti-accidental touch device 8, under the reaction force of the second spring 85, the second spring 85 pushes the protective plate 83 along the inside of the guide rail 81 towards the concave post 2, so that the protective plate 83 drives the positioning post 84 along the sliding hole. The internal sliding mechanism 82 allows the positioning post 84 to move to its maximum position along the sliding hole 82, causing the protective plate 83 to be located on one side of the controller 3 and completely covering the buttons on the controller 3. At the same time, it intercepts external objects, preventing them from contacting the buttons on the controller 3, thereby preventing accidental touches of the buttons on the controller 3. This reduces the risk of personnel accidentally touching the buttons on the controller 3 during operation, which could alter the operating program of the machine body 1 and affect the normal winding of the packaging boxes. A handle 86 is fixedly connected to one side of the protective plate 83. The inner side of the handle 86 has multiple anti-slip protrusions. By setting the handle 86, it provides a point of leverage for personnel, allowing them to easily move the protective plate 83 by manually moving the handle 86.
[0035] Working principle: First, the stacked packaging boxes are placed on the worktable of machine body 1, so that the stacked packaging boxes are positioned in the middle of the concave column 2. Then, the strapping tape on the feed spool 4 is drawn into the machine body 1 through the feed pipe 5 by the conveying mechanism inside machine body 1. Then, the strapping tape is ejected through the concave column 2 and the wire hole 6 on the worktable by the conveying mechanism inside machine body 1 and wrapped around the stacked packaging boxes. At the same time, the tightening mechanism inside machine body 1 pulls and tightens the strapping tape. Then, the heating plate inside machine body 1 extends to the intersection of the two ends of the strapping tape to heat it, so that the two ends of the strapping tape are thermally fused and fixed together. Then, the cutter inside machine body 1 pushes out to cut the strapping tape, thus achieving the winding process of the packaging boxes.
[0036] First, place the stacked packaging boxes on the worktable of machine body 1, positioned in the middle of the concave pillar 2, so that the packaging boxes are below the perforated plate 75. Then, start motor 73, which drives gear 74 to rotate. The meshing of gear 74 and rack 72 causes gear 74 to move rack 72 closer to machine body 1, which in turn moves perforated plate 75 closer to machine body 1. Perforated plate 75 then moves two clamping plates 712 closer to machine body 1. When perforated plate 75 is close to the surface of the topmost packaging box, the surfaces of the two clamping plates 712 come into contact with the surface of machine body 1. The two clamping plates 712 then move up and down along the inside of perforated plate 75 to match the height of the stacked packaging boxes. Simultaneously, activate two electric telescopic rods 7... 10. The two electric telescopic rods 710 simultaneously drive the two sliders 711 to move in opposite directions, causing the two sliders 711 to pull the clamping plates 712 to move in opposite directions along the inside of the perforated plate 75. The two clamping plates 712 drive the two first springs 713 and the concave plate 714 to slide along the surface of the perforated plate 75. When the two clamping plates 712 move in opposite directions to the position of simultaneously pressing the surface of the packaging boxes, the two clamping plates 712 press the sides of the stacked packaging boxes and align them. At this time, the motor 73 continues to drive the gear 74 to move the rack 72, causing the rack 72 to continue to drive the perforated plate 75 to move closer to the machine body 1. When the perforated plate 75 moves to the position of pressing the surface of the packaging boxes, the perforated plate 75 compacts the stacked packaging boxes, achieving alignment and compression of the stacked packaging boxes.
[0037] Under the reaction force of the second spring 85, the second spring 85 pushes the protective plate 83 to move along the inside of the guide rail 81 towards the concave post 2, so that the protective plate 83 drives the positioning post 84 to slide along the inside of the sliding hole 82. When the positioning post 84 moves to the maximum position along the inside of the sliding hole 82, the protective plate 83 is located on one side of the controller 3 and completely covers the button on the controller 3. At the same time, it intercepts external objects and prevents external objects from contacting the button on the controller 3, thereby achieving the anti-accidental touch treatment of the button on the controller 3.
