Abstract
Description
A rolling device for processing metal edging of glass pot lids Technical Field
[0001] This utility model relates to the technical field of glass product processing equipment, and in particular to a rolling edge device for processing metal edging of glass pot lids. Background Technology
[0002] Glass pot lids are a common cooking utensil accessory in modern kitchens, widely used in various cookware due to their transparency, heat resistance, and ease of cleaning. To improve the structural strength and aesthetics of the lid's edge, a metal ring is usually wrapped around the outside of the glass lid. This metal ring not only protects the glass edge from impacts and damage but also enhances the decorative effect through polishing and brushing processes, while simultaneously improving the overall sealing and lifespan of the lid. Currently, the metal edging process is mostly completed manually or with semi-automated equipment, and there is still considerable room for improvement in processing efficiency and consistency.
[0003] Existing metal edging processing equipment typically employs a step-by-step pressing method. Specifically, the operator first places the metal ring around the outer edge of a glass lid, then places the lid horizontally on a rotating worktable and clamps it in place. Once the equipment is started, the worktable rotates the lid, and the pressure rod presses against the outer edge of the metal ring, causing it to gradually bend inwards and conform to the glass edge. During this process, the pressure parameters of the pressure rod and the rotation speed of the worktable need to be manually adjusted according to the metal material and the size of the lid.
[0004] However, the initial positioning of the metal ring and the glass lid depends on manual operation. If the lid is not accurately placed at the center of the worktable, the metal ring may be subjected to uneven force during the rotation and pressing process, which may lead to problems such as edge offset, poor local fit, or even glass breakage due to eccentric force. Summary of the Invention
[0005] The technical problem to be solved by this utility model is insufficient positioning accuracy, and an automatic correction rolling edge device for metal edging processing of glass pot lids is provided.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rolling edge device for metal edging processing of glass pot lids, including a base, a gantry frame, a clamping cylinder, a rolling edge assembly, a placement platform, a controller, a fixing plate, a motor, a bidirectional reciprocating screw, a guide rod, a straightening plate, and a pressing component. The base is equipped with a gantry frame, and two placement platforms are rotatably connected to the base. Two clamping cylinders are installed on the gantry frame. A rolling edge assembly for pressing the edge is installed in the middle of the gantry frame. A controller is installed on the front side of the base. The clamping cylinders are wired to the controller. Several fixing plates are connected to the base. The fixing plates are all located on the left and right sides of the placement platforms. Both ends of the bidirectional reciprocating screw are rotatably connected to the fixing plates. A motor is installed on the fixing plate. The motor is connected to one end of the bidirectional reciprocating screw and wired to the controller. A guide rod is connected between the fixing plates. One end of the straightening plate is threadedly connected to the bidirectional reciprocating screw, and the other end is slidably connected to the guide rod. A pressing component for pressing down the pot lid is provided in the middle of the straightening plate.
[0007] A further preferred embodiment of this utility model is as follows: the pressing component includes a mounting base, a pressure plate, a rotating shaft, a torsion spring, and a roller. The mounting base is connected to the middle of the straightening plate, and the rotating shaft is rotatably connected inside the mounting base. One end of the pressure plate is rotatably connected to the rotating shaft, and the other end is rotatably connected to a roller. The roller contacts the pot lid. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the pressure plate, and the other end is connected to the rotating shaft. The length of the pressure plate is less than the stroke of the straightening plate.
[0008] A further preferred embodiment of this utility model is as follows: it also includes a connecting plate and an operating rod. Several slots are opened on both the left and right sides of the mounting base. A connecting plate is sleeved at the connection between the rotating shaft and the mounting base. The connecting plate is slidably connected to the pressure plate. A sliding groove is opened in the connecting plate. The middle part of the operating rod is slidably connected to the sliding groove of the connecting plate. The two ends of the operating rod are slidably connected to the slots of the mounting base.
[0009] A further preferred embodiment of this utility model is: it also includes a guide ring, and a guide ring is connected to each slot port, the guide ring being provided with an inwardly inclined slope.
[0010] A further preferred embodiment of this utility model is: it also includes magnets, with magnets connected to the inner ends of the slots, and the operating rod is made of magnetic material.
[0011] A further preferred embodiment of this utility model is that it also includes a foam pad, and the roller is fitted with a foam pad.
[0012] A further preferred embodiment of this utility model is: it also includes anti-collision pads, and a group of straightening plates forming a circle are all connected to anti-collision pads around the inner side.
[0013] A further preferred embodiment of this utility model is: it also includes a telescopic sleeve, and a telescopic sleeve is fitted on both the bidirectional reciprocating lead screw and the guide rod. The telescopic sleeve on each bidirectional reciprocating lead screw or guide rod is divided into three sections by two straightening plates, and the two ends of the telescopic sleeve are respectively connected to the fixed plate and the straightening plate.
[0014] Compared with the prior art, the advantages of this utility model are: through the linkage design of the bidirectional reciprocating screw and the guide rod, the centering plate is driven to slide synchronously towards the center along the predetermined trajectory. With the flexible contact of the anti-collision pad and the rolling guidance of the roller, the pot lid is automatically centered during the placement stage. The pressure plate squeezes the pot lid and deflects it around the rotating shaft. The torsion spring stores the force to balance the pressure, ensuring that the pushing force applied by the centering plate is uniform and adapts to the position deviation of the pot lid, thereby accurately pushing the pot lid to the center point of the placement platform.

[0025] This embodiment mainly describes the structure of the pot lid edge-sealing machine, as follows:
[0026] A edging device for metal edging processing of glass pot lids, as shown in Figures 1-6, includes a base 1, a gantry frame 2, clamping cylinders 3, an edging assembly 4, a placement platform 5, a controller 6, a fixing plate 7, a motor 8, a bidirectional reciprocating lead screw 9, a guide rod 10, a straightening plate 11, and a pressing assembly. The gantry frame 2 is mounted on the base 1, and two placement platforms 5 are rotatably connected to the base 1. Two clamping cylinders 3 are mounted on the gantry frame 2. A power assembly for driving the placement platforms 5 to rotate is installed inside the base 1. The clamping cylinders 3 cooperate with the placement platforms 5 to clamp the pot lid. An edging assembly 4 for pressing the edge is installed in the middle of the gantry frame 2. A controller 6 is installed on the front side of the base 1. The clamping cylinders 3 and the controller 6 are connected to the gantry frame 2. The device 6 is wired, and eight fixing plates 7 are connected to the base 1. Two fixing plates 7 are set on the left and right sides of each placement platform 5. Both ends of the bidirectional reciprocating screw 9 are rotatably connected to the two fixing plates 7 on the same side. A motor 8 is installed on the fixing plate 7 at the rear end of the same side of the placement platform 5. The output shaft of the motor 8 is fixedly connected to the rear end of the bidirectional reciprocating screw 9. The motor 8 is wired to the controller 6. A guide rod 10 is connected between the fixing plates 7. One end of the straightening plate 11 is threadedly connected to the bidirectional reciprocating screw 9, and the other end is slidably connected to the guide rod 10. The two straightening plates 11 form a circle around the placement platform 5. A pressing component for pressing down the pot lid is set in the middle of the straightening plate 11.
[0027] As shown in Figures 2 and 4, the pressing assembly includes a mounting base 12, a pressure plate 13, a rotating shaft 14, a torsion spring 15, and a roller 16. The mounting base 12 is connected to the middle of the straightening plate 11. The rotating shaft 14 is rotatably connected inside the mounting base 12. One end of the pressure plate 13 is rotatably connected to the rotating shaft 14, and the other end is rotatably connected to the roller 16. The roller 16 contacts the pot lid. The rotating shaft 14 is fitted with a torsion spring 15. One end of the torsion spring 15 is connected to the pressure plate 13, and the other end is connected to the rotating shaft 14. The length of the pressure plate 13 is less than the travel distance of the straightening plate 11.
[0028] As shown in Figures 4-6, it also includes a connecting plate 17 and an operating lever 20. Several slots 19 are opened on both the left and right sides of the mounting base 12. The connecting plate 17 is sleeved at the connection between the rotating shaft 14 and the mounting base 12. The connecting plate 17 is slidably connected to the pressure plate 13. A sliding groove 18 is opened in the connecting plate 17. The middle part of the operating lever 20 is slidably connected in the sliding groove 18 of the connecting plate 17, and both ends of the operating lever 20 are slidably connected in the slots 19 of the mounting base 12.
[0029] As shown in Figure 5, it also includes a guide ring 21. A guide ring 21 is connected to each port of the card slot 19. The guide ring 21 is provided with an inwardly inclined slope.
[0030] As shown in Figure 5, it also includes a magnet 22. The inner end of the slot 19 is connected to a magnet 22, and the operating rod 20 is made of magnetic material.
[0031] As shown in Figure 4, it also includes a foam pad 23. The roller 16 is fitted with a foam pad 23, and the foam pad 23 covering the roller 16 buffers the contact pressure.
[0032] As shown in Figure 2, it also includes anti-collision pads 24. A set of straightening plates 11 forming a circle are all connected to anti-collision pads 24 around the inner side. The anti-collision pads 24 on the inner side of the straightening plates 11 are made of elastic material and buffer the impact force through deformation when in contact with the pot lid.
[0033] As shown in Figure 1, it also includes a telescopic sleeve 25. The telescopic sleeve 25 is fitted on both the bidirectional reciprocating screw 9 and the guide rod 10. The telescopic sleeve 25 on each bidirectional reciprocating screw 9 or guide rod 10 is divided into three sections by two straightening plates 11. The two ends are connected to the fixed plate 7 and the straightening plate 11 respectively to prevent dust or debris from interfering and to ensure the stability of the moving trajectory of the straightening plate 11.
[0034] The staff placed the glass pot lid with the ring on it onto the placement platform 5. Then, the controller 6 activated the clamping cylinder 3 and the motor 8. The power unit inside the base 1 worked in conjunction with the clamping cylinder 3 to start. The motor 8 drove the bidirectional reciprocating screw 9 to rotate, thereby driving the straightening plate 11 to move towards the center. The other end of the straightening plate 11 slid on the guide rod 10. The telescopic sleeve 25 wrapped around the bidirectional reciprocating screw 9 and the guide rod 10, isolating external interference and ensuring the stability of the moving trajectory of the straightening plate 11. Both straightening plates 11 moved towards the center simultaneously. As the pressure plate 13 moves, it follows the movement of the straightening plate 11. Since the length of the pressure plate 13 is less than the range of movement of the straightening plate 11, when the straightening plate 11 moves to contact the fixed plate 7, the inner end of the pressure plate 13 has not yet extended into the top area of the placement platform 5, thus not affecting the worker's placement of the pot lid. As the straightening plate 11 moves, the anti-collision pad 24 on the inner ring of the straightening plate 11 pushes the pot lid, and the roller 16 at the bottom of the pressure plate 13 contacts the pot lid. When the pressure plate 13 presses the pot lid, it rotates around the rotating shaft 14, torturing the torsion spring 1. 5. The straightening plate 11 pushes the pot lid to the center point of the placement platform 5 from both the front and rear sides. The roller 16 at the end of the pressure plate 13 rotates with the pot lid without leaving friction scratches. The foam pad 23 on the roller 16 further optimizes the contact effect and ensures the surface quality of the pot lid. The motor 8 continues to drive the bidirectional reciprocating screw 9 to rotate. At this time, the straightening plate 11 moves away from the pot lid along the bidirectional reciprocating screw 9. After the piston rod of the clamping cylinder 3 presses down and contacts the pot lid, the controller 6 simultaneously starts the power component in the base 1 to drive the placement platform 5 to rotate. The edge rolling component 4 moves the pressure rod to squeeze the metal ring. The pot lid rotates on the placement platform 5. The straightening plate 11 slides to both sides. During the process of the pressure plate 13 gradually separating from the pot lid, the torsion spring 15 twists back, causing the pressure plate 13 to rotate and reset, thus completing the edge rolling on one side. The piston rod of the clamping cylinder 3 resets upward, the placement platform 5 stops rotating, and the edge rolling component 4 drives the pressure rod to separate from the pot lid. The staff takes out the pot lid and puts it on another placement platform 5 to perform edge rolling on the other side of the pot lid.
[0035] Since the sides of the pot lid are concave and convex, the shape of the placement platform 5 is adjusted accordingly. Two placement platforms 5 are placed together to cover both sides of the pot lid. For pot lids with different sides, the operating rod 20 is pulled out. The two ends of the operating rod 20 are disengaged from the slot 19, while the middle part of the operating rod 20 remains in the sliding groove 18. Then, the operating rod 20 is rotated, which drives the connecting plate 17 to rotate. This, in turn, adjusts the tilt angle of the pressure plate 13 through the rotating shaft 14. Due to the torque of the torsion spring 15, the pressure plate 13 rotates with the rotating shaft 14, thereby adjusting the tilt angle of the pressure plate 13. The tilt angle of the pressure plate 13 is adjusted according to the top or bottom surface of the pot lid. After adjustment, the operating rod 20 slides into the slot 19 along the inclined surface of the guide ring 21 and is attracted and fixed by the magnet 22 to ensure a stable connection.
