Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment, and in particular to a Y-direction flanging mechanism for ear loop labels. Background Technology

[0002] In the production of loop labels, during continuous die-cutting, a crescent-shaped notch is formed on the material, with a loop extending from the notch. Subsequent processes require folding this loop outwards 180° and flattening it to create an easy-tear opening or label ear. Traditionally, a cylinder is used to lift the loop separately, followed by manual folding or folding with a rotating hook plate. The cylinder requires an external air source, resulting in slow response and low cycle time. Furthermore, the lifting timing is difficult to synchronize with the main die-cutting action, easily causing positioning errors and loop rebound, affecting the yield. In addition, the lack of timely flattening after folding makes the loop prone to rebound, causing it to stick to waste material during subsequent waste removal, leading to an increased scrap rate.

[0003] Therefore, there is an urgent need for a Y-axis flipping mechanism for ear loop labels to achieve automated and precise flipping of ear loop labels in a continuous production line. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a Y-direction flanging mechanism for ear loop labels.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: The Y-axis flapping mechanism for the hook label includes a material conveying line set along the x-axis direction. The material is conveyed by a pull roller. The material has several notches arranged along the y-axis direction. The shape of the notches forms a hook extending from the material in the y-axis direction. The hanging ear has a movable end facing the notch and a connecting end connected to the material body. The material conveying line is equipped with a lifting station and a flanging station. Below the lifting station, there are several lifting components arranged along the y-axis. The lifting components are connected to a lifting power source that drives their lifting and lowering motion. Under the drive of the lifting power source, the corresponding hanging ear is lifted up, and the hanging ear is in a tilted state. Above the flanging station is an installation beam. Along the y-axis, there are several translational flanging components that correspond to the number of lugs in each row. The installation beam is connected to a translational power source. When the lug is in the flanging station, the translational power source drives the installation beam to push along the y-axis from the movable end of the lug to the connecting end. The translational flanging components push the lug to fold away from the movable end.

[0006] Driven by a lifting power source, the lifting component raises the lugs to an upturned position, while the lateral flanging component utilizes the inertia of the material conveying to flip the lugs outward. This solves the problem of low cylinder efficiency. By using the horizontal movement of the mechanical lifting and lateral flanging components to flip the lugs, the coordination of the equipment's movements is improved, achieving automatic and precise flanging of the lugs. Preferably, a pressing station is located downstream of the flanging station. The pressing station has an upper pressing plate and a lower supporting plate on its upper and lower sides. The upper pressing plate is connected to a pressing power source that drives its up-and-down movement. The upper pressing plate and the lower supporting plate work together to flatten the folded hanging ear. This flattening action of the upper pressing plate and lower supporting plate helps to solidify the creases, ensuring the hanging ear is fully shaped in its folded state. Preferably, the mounting beam passes through the fixed base along the y-axis, and the lower support plate is fixedly connected to the fixed base so that the material passing through the flanging station can be connected to the flanging station. The flanged hanging ear immediately enters the pressing station for pressing, pressing the folded state of the hanging ear to prevent the folded hanging ear from rebounding during transportation.

[0007] Preferably, a die-cutting station is set on the material conveying line. The die-cutting station is located upstream of the lifting station. An upper die and a lower die are set on the upper and lower sides of the die-cutting station, respectively. The upper die and the lower die move relative to each other to form a notch in the material.

[0008] Preferably, the upper die is connected to a lifting power source, which drives the upper die to move up and down. The upper die and the upper lifting component are connected by a transmission assembly. This achieves an integrated design, synchronizing die-cutting and lifting actions, avoiding control delays from independent cylinders, and improving overall efficiency. At the same time, it reduces equipment complexity and saves energy and maintenance costs. Preferably, the transmission assembly includes a lifting frame, a lower ejector rod, a connecting rod, and a connecting rod seat. The lifting frame is fixedly connected to the upper mold. The upper ejector components are arranged along the y-axis and mounted on the ejector seat. The lower ejector rod, which moves synchronously with the lifting frame, is mounted on the lifting frame. The lower ejector rod and the ejector seat are linked by a connecting rod. The middle section of the connecting rod is hinged to the connecting rod seat, so that the ejector seat is pushed up when the lower ejector rod is pressed down. This ensures the accuracy and stability of the lifting action and prevents mechanical impact. At the same time, the height of the upper ejector components on the ejector seat is adjustable to adapt to different material thicknesses and improve versatility. Preferably, the assembly also includes a frame beam with a vertically extending guide shaft mounted on it via bearings. A bearing housing is mounted on the guide shaft, and a pin seat is mounted on the bearing housing and moves up and down along the axial direction of the guide shaft. A connecting rod is fixed between the bearing housings on both sides of the y-axis, and the connecting rod extends out of the bearing housing. Contact components are mounted on both ends of the connecting rod. When the lower push rod presses down, it causes the contact component on one side of the connecting rod seat to move down, and the contact component on the other side of the connecting rod seat pushes the connecting rod upward, causing the upper push component to move upward.

[0009] Preferably, a spring is installed between the bearing housing and the frame beam to cushion the ejector pin seat from falling back under gravity. The spring cushions the impact of the ejector pin seat's return stroke, reduces noise, and extends its service life.

[0010] Preferably, the lifting frame is equipped with a baffle roller, which forms an extended crease along the x-axis between the raised portion of the lifting station and the horizontal portion of the material. The baffle roller abuts against the side of the hanging lug that is raised after the upper lifting component is lifted. After lifting, the baffle roller abuts against the hanging lug, providing support for the hanging lug in its raised, upright position.

[0011] Preferably, the pull roller is located downstream of the pressing station. A waste removal blade extending along the y-axis is positioned above the upper surface of the pull roller, away from the pressing roller in the x-axis direction. When the material deforms and bends against the pull roller, an angle difference is formed between the waste at the notch and the material body. The waste is blocked by the waste removal blade and detaches from the material body. The waste removal blade utilizes the bending angle difference of the material to separate the waste, thus solving the problem of waste residue. This utility model, by adopting the above technical solution, has significant technical effects: The integrated production line design enables the Y-axis flanging of the ear tag along the material extension direction, achieving a fast and continuous flanging process with a high success rate, reducing ear rebound rate, eliminating the need for external air circuits, and featuring a compact structure suitable for high-speed ear tag production lines.

[0012] This allows punching, lifting, and flanging to be completed within the same cycle, reducing repeated positioning errors, lowering equipment costs, and reducing the space occupied by the equipment.

[0013] Furthermore, by leveraging the power of die-cutting through mechanical linkage, lifting, flanging, and die-cutting are synchronized, increasing production speed. The equipment integrates stop rollers, pressure rollers, and hooks to ensure that the flanged ears remain in the flanged state after flanging, resulting in a high yield. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] Example 1 The Y-axis flip-edge mechanism of the ear loop label, such as Figure 3-4 As shown, it includes a material conveying line arranged along the x-axis direction. The material 1 is conveyed by the pull roller 2. The material 1 is provided with a number of notches 11 arranged along the y-axis direction. The shape of the notches 11 forms a hanging ear 12 that extends the material in the y-axis direction. like Figure 5 As shown, the hanging ear 12 has a movable end facing the notch 11 and a connecting end connected to the material 1 body. A lifting station and a flanging station are provided on the material conveying line. Several lifting components 3 are arranged along the y-axis below the lifting station. The lifting components 3 are connected to a lifting power source that drives their lifting and lowering movement. Under the drive of the lifting power source, the corresponding hanging ear 12 is lifted up, and the hanging ear 12 is in a tilted state. Above the flanging station is an installation beam 41. Along the y-axis, the installation beam 41 is provided with several translational flanging components 42 corresponding to the number of hanging ears 12 in each row. The installation beam 41 is connected to a translational power source 43. When the hanging ear is in the flanging station, the translational power source 43 drives the installation beam 41 to push along the y-axis from the movable end of the hanging ear 12 to the connecting end. The translational flanging components push the hanging ear 12 to fold away from the movable end.

[0018] Driven by the lifting power source, the lifting component 3 lifts the hanging ear 12 to a tilted state, while the lateral flipping component uses left and right movement to flip the hanging ear outward.

[0019] Downstream of the flanging station is a pressing station. The pressing station has an upper pressing plate 44 and a lower supporting plate 45 on its upper and lower sides. The upper pressing plate 44 is connected to a pressing power source 46 that drives it to move up and down. The upper pressing plate 44 and the lower supporting plate 45 work together to flatten the folded hanging ear 12.

[0020] The mounting beam 41 is installed along the y-axis on the fixed seat 47, and the lower support plate 45 is fixedly connected to the fixed seat 47 so that the material 1 passing through the flanging station can be connected to the flanging station.

[0021] like Figure 1-2 As shown, a die-cutting station is set on the material conveying line. The die-cutting station is located upstream of the lifting station. An upper die 51 and a lower die 52 are set on the upper and lower sides of the die-cutting station, respectively. The upper die 51 and the lower die 52 move relative to each other to die-cut the material 1 to form a notch 11.

[0022] The upper mold 51 is connected to the lifting power source, which drives the upper mold 51 to move up and down. The upper mold 51 and the upper top component 3 are connected by a transmission assembly.

[0023] like Figure 4 As shown, in one embodiment, the transmission assembly includes a lifting frame 61, a lower ejector rod 62, a connecting rod 63, and a connecting rod seat 64. The lifting frame 61 is fixedly connected to the upper mold 51. The upper ejector component 3 is arranged along the y-axis direction and mounted on the ejector seat 31. The lower ejector rod 62, which moves synchronously with the lifting frame 61, is mounted on the lifting frame 61. The lower ejector rod 62 and the ejector seat 31 are linked by the connecting rod 63. The middle section of the connecting rod 63 is hinged to the connecting rod seat 64, so that the ejector seat 31 is pushed up when the lower ejector rod 62 is pressed down.

[0024] It also includes a frame beam 71, on which a vertically extending guide shaft 73 is mounted via a bearing 72. A bearing seat 74 is mounted on the guide shaft 73. The ejector pin seat 31 is mounted on the bearing seat 74 and moves up and down along the axial direction of the guide shaft 73. A connecting rod 75 is fixed between the bearing seats 74 on both sides of the y-axis. The connecting rod 75 extends out of the bearing seat 74. Contact parts 65 are installed at both ends of the connecting rod 63. When the lower ejector rod 62 presses down, it causes the contact part 65 on one side of the connecting rod seat 64 to move down. The contact part 65 on the other side of the connecting rod seat 64 pushes the connecting rod 75 upward, causing the upper ejector pin 3 to move upward.

[0025] A spring 76 is installed between the bearing housing 74 and the frame beam 71 to buffer the ejector pin seat 31 from falling back under gravity.

[0026] The lifting frame 61 is equipped with a baffle roller 8. The baffle roller 8 forms an extended crease in the x-axis direction between the raised part of the lifting station and the horizontal part of the material 1. The baffle roller 8 abuts against the side of the hanging ear 12 that is raised after the upper lifting component 3 is lifted.

[0027] It also includes pressure roller 9, which is located downstream of hook 42. The pressure rollers 9 on the upper and lower sides work together to flatten the flanged hanging ear 12.

[0028] The pulling roller 2 is located downstream of the pressing station. The pulling roller 2 has a waste removal knife 21 extending along the y-axis direction above its upper surface away from the pressing roller 9 in the x-axis direction. When the material 1 deforms and bends against the pulling roller 2, an angle difference is formed between the waste at the notch 11 and the body of the material 1. The waste is blocked by the waste removal knife 21 and detached from the body of the material 1.

[0029] Working principle: 1. Material 1 is a continuous material, such as paper, film, or plastic rolls, which is conveyed along the x-axis by the feed roller 2. The upper die 51 and lower die 52 of the die-cutting station move relative to each other. The upper die 51 and lower die 52 each have a cutting tool that matches the shape of the notch 11. Each action forms the notch 11 on the material. The specific structure and working principle of the die-cutting machine are conventional techniques for those skilled in the art and will not be described in detail here. The notch 11 is punched at the die-cutting station to form a notch and a hanging ear 12. After a single die-cut, each notch 11 is arranged along the y-axis. After the material is conveyed forward, continuous die-cutting can be used as needed. After each processing, multiple rows of notches 11 are arranged in a matrix, wherein the hanging ear initially protrudes to one side in the y-axis direction. 2. After die-cutting, the material enters the lifting station, and the lifting power source drives the transmission components to move.

[0030] In one feasible implementation, the lifting power source is shared with the upper mold 51. The lifting frame 61 is fixed to the upper mold 51. When the upper mold 51 descends, the lower ejector rod 62 presses against the contact part 65 on one side of the connecting rod 63. The connecting rod 63 is hinged to the connecting rod seat 64. The other side of the connecting rod 63, together with the contact part 65 on that side, pushes upward, thereby pushing the connecting rod 75 upward. The connecting rod 75 and the bearing seat 74 rise together, causing the ejector pin seat 31 to drive the upper ejector component 3 to rise. Each die-cutting action corresponds to one upward ejection, and the production cycle can be perfectly matched. The upper ejector component 3 is arranged along the y-axis, and the lifting corresponds to the hanging ear to the tilted state. When the lifting power source raises the upper mold 51, the connecting rod 63 no longer provides upward force at the location of the connecting rod 75. The ejector pin seat descends under its own weight, the spring 74 buffers the return of the ejector pin seat, and the guide shaft 73 restricts the horizontal degree of freedom of the bearing seat 74.

[0031] A crease is formed between the top hanging ear 12 and the plane where the material 1 has a notch. The hanging ear 12 is blocked by the stop roller 8, which abuts against the tilted hanging ear 12 to prevent it from springing back. The hanging ear 12 continues to be conveyed forward along the x-direction in the tilted or upright state.

[0032] 3. The material enters the flanging station. Each translational flanging component 42 is located on one side of the movable end of the hanging ear. The translational power source 43 drives the mounting beam 41 to push from the movable end of the hanging ear 12 towards the connecting end along the y-axis. The translational flanging component 42 pushes the hanging ear 12 to generate a displacement relative to the connecting end in the y-axis direction, so that the movable end passes over the connecting end and is folded. The hanging ear 12 is in the opposite direction to the material 1 from the initial state. The material 1 continues to be conveyed to the lower support plate 45. The mounting beam 41 moves laterally to reset. The pressing power source 46 drives the upper pressing plate 44 to descend and flatten the hanging ear.

[0033] 4. The material reaches the pull roller 2 and bends against it. The waste removal knife 21 uses the bending angle difference of the material to block and remove the waste, and then the finished product is output. By synchronizing the die-cutting stop with the translation and flanging components, and the pressing of the upper pressure plate 44 and the lower support plate 45, the coordination of the equipment's movements can be improved, ensuring the flanging of the hanging ears.
