Description

Technical Field

[0001] This utility model relates to the field of metal product processing, and in particular to a rolling edge device for metal edging of pot lids. Background Technology

[0002] In daily life, pot lids are an important part of kitchen utensils, not only serving the function of sealing cooking containers but also directly affecting heat retention and food flavor during cooking. With improved living standards and continuous advancements in cooking technology, modern pot lids are designed with a greater emphasis on both aesthetics and practicality. Metal edging not only strengthens the lid's edges, preventing deformation due to high temperatures or external forces, but also effectively enhances the lid's sealing performance, ensuring no steam leakage during cooking and thus locking in the original flavor of the food.

[0003] In the production process of pot lids, the connection between the metal ring and the lid body is a crucial step. To achieve a secure bond, the metal ring usually needs to be rolled before installation. Rolling refers to using specific machinery to bend the edge of the metal ring into a specific shape so that it can better fit into the groove on the edge of the pot lid. This is achieved through physical snap-fitting or adhesive methods, resulting in a connection that is both aesthetically pleasing and practical.

[0004] However, on current metal edging production lines for pot lids, the edging of the metal rings and the feeding and unloading processes rely on manual operation. Workers need to frequently come into close contact with the edging machinery to place and remove the metal rings. This method of operation is not only inefficient, but also highly prone to worker injury due to careless operation or improper machinery operation, posing significant safety hazards.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the structure of the edge-rolling equipment, as follows:

[0026] Equipment for rolling the metal edging of pot lids, such as... Figures 1-6 As shown, the assembly includes a base 1, a controller 101, a curling machine 102, operating stations 2, a mounting base 3, a gear ring 4, a first fixed base 5, a first motor 6, a gear 7, a rotating ring 8, a feeding assembly, and a discharging assembly 14. Two symmetrically arranged curling machines 102 are mounted on the base 1. The controller 101 is mounted on each curling machine 102. Each curling machine 102 mainly consists of an electric push rod and two curling wheels at the bottom. Two symmetrical operating stations 2 are provided on the base 1, with the two operating stations 2 and the two curling machines 102 positioned opposite each other. The components are distributed on the base 1. The base 1 is connected to the middle of the mounting seat 3. The mounting seat 3 is rotatably connected to the rotating ring 8. The bottom of the rotating ring 8 is connected to the gear ring 4. The mounting seat 3 is connected to the side of the first fixed seat 5. The first fixed seat 5 is equipped with the first motor 6. The controller 101 is wired to the first motor 6. The output shaft of the first motor 6 faces upward and is connected to the gear 7. The gear 7 meshes with the gear ring 4. The rotating ring 8 is provided with a feeding component for placing the metal ring. The base 1 is provided with a discharging component 14 for storing the raw material of the metal ring.

[0027] like Figure 2 and Figure 3 As shown, the feeding assembly includes a second fixed base 9, a second motor 10, a lever 11, a connecting plate 12, and a placement disc 13. The second fixed base 9 is connected to the base 1 and is located below the edge rolling machine 102. The second motor 10 is installed on the second fixed base 9. The controller 101 is wired to the second motor 10. The output shaft of the second motor 10 faces upward and is fixedly connected to the lever 11. The two ends of the lever 11 are set as cones. The outer ring of the rotating ring 8 is rotatably connected to the connecting plate 12. Four positioning rods are set at the bottom of the connecting plate 12. The distance between the positioning rods is slightly larger than the width of the lever 11, providing a fit tolerance for the annular path of the connecting plate 12. The positioning rods are pressed and fitted with the lever 11. The top of the connecting plate 12 is connected to the placement disc 13. The placement disc 13 is used to fit the metal ring and is lower than the height of the metal ring. The edge rolling machine 102 does not need to contact the placement disc 13.

[0028] like Figure 1 and Figure 6 As shown, the feeding assembly 14 includes a housing 141, an electric slide rail 142, a moving plate 143, and a control switch 144. The housing 141 is placed on the base 1. Two electric slide rails 142 are installed on the front and rear sides of the housing 141 respectively. The moving plate 143 is slidably connected inside the housing 141. The electric slide rails 142 are used to drive the moving plate 143 to slide up and down. The control switch 144 is provided on the outside of the housing 141. The control switch 144 is wired to the electric slide rails 142 and controls the start, stop, and driving direction of the electric slide rails 142.

[0029] Two operators sit at operating stations 2, respectively, and take out a metal ring from the housing 141 of the feeding assembly 14 and place it on the placement disc 13 of the feeding assembly. Then, the controller 101 starts the crimping machine 102, the first motor 6, and the second motor 10. The first motor 6 drives the gear 7 to rotate, which in turn drives the gear ring 4 and the rotating ring 8 to rotate, thereby rotating the feeding assembly. When the gear ring 4 rotates 90 degrees, the placement disc 13 containing the metal ring is below the crimping machine 102. At this time, the electric push rod of the crimping machine 102 pushes the rolling wheel downwards. When the rolling wheel contacts the metal ring, it... The second motor 10 rotates the placement disc 13, and the rolling wheel gradually presses downward to complete the edge rolling of the metal ring. Then the edge rolling machine 102 resets, and the first motor 6 continues to drive the rotating ring 8 to rotate. After rotating 90 degrees again, the operator at the object operation station 2 can remove the edge-rolled metal ring and put in the metal ring to be rolled. The operator at the operation station 2 does the same, completing the material picking and unloading steps at the same time, and keeping both steps away from the edge rolling machine 102. This ensures safety during the work process while coordinating with each other to complete the edge rolling, material picking, and material unloading steps simultaneously, thus improving work efficiency.

[0030] When the first motor 6 is started, the rotating ring 8 rotates, which drives the connecting plate 12 to rotate around the mounting base 3, thereby rotating the metal ring on the placed disc 13 to below the edge rolling machine 102. When the connecting plate 12 is close to the edge rolling machine 102, its bottom is slidably connected to the lever 11. The shape of the lever 11 ensures the position of the connecting plate 12. When the edge rolling is performed, the second motor 10 is started. The second motor 10 drives the connecting plate 12 and the placed disc 13 to rotate through the lever 11, thereby rotating the metal ring. This cooperates with the edge rolling machine 102 to perform edge rolling on the metal ring. After the edge rolling is completed, the connecting plate 12 is smoothly separated from the lever 11.

[0031] When retrieving materials, the electric slide rail 142 is activated by the control switch 144. The electric slide rail 142 drives the moving plate 143 to move upward, thereby pushing the metal ring upward, making it convenient for workers to pick up. This eliminates the need to bend over or reach into the box 141 to retrieve the metal ring, thus optimizing the work process.

[0032] like Figure 2 and Figure 5As shown, it also includes a fixed plate 15, a limiting rod 16, a return spring 17, and a roller 18. The mounting base 3 has flat surfaces on both sides near the edge rolling machine 102. The inner ring of the rotating ring 8 is connected to four fixed plates 15, and each fixed plate 15 corresponds to a connecting plate 12. The limiting rod 16 is slidably connected inside the fixed plate 15. The roller 18 is rotatably connected to the limiting rod 16 facing the mounting base 3. The return spring 17 is sleeved on the limiting rod 16. One end of the return spring 17 is connected to the limiting rod 16, and the other end is connected to the fixed plate 15. The end of the limiting rod 16 away from the mounting base 3 is pressed and engaged with the connecting plate 12.

[0033] When the rotating ring 8 drives the connecting plate 12 to rotate, the limiting rod 16 rotates with the connecting plate 12. The roller 18 is rotatably connected to the mounting base 3, the return spring 17 is compressed, and the limiting rod 16 abuts against the cylinder in the middle of the connecting plate 12, restricting the rotation of the connecting plate 12. Since the plane of the mounting base 3 is close to the edge rolling machine 102, when the placement disc 13 is located at the bottom of the edge rolling machine 102, the roller 18 contacts the plane. At this time, the limiting rod 16 gains room to move, the return spring 17 rebounds, and the limiting rod 16 disengages from the connecting plate 12, making it easier for the second motor 10 to drive the connecting plate 12 and the placement disc 13 to rotate. In other areas, the rotation of the connecting plate 12 is restricted, thereby ensuring the stable cooperation between the lever 11 and the connecting plate 12. The connecting plate 12 can maintain the same angle to connect with the lever 11, ensuring the stability of the processing process.

[0034] like Figure 5 As shown, it also includes a rubber pad 19. The side of the limiting rod 16 that contacts the connecting plate 12 is connected to the rubber pad 19 to increase the friction between the limiting rod 16 and the connecting plate 12.

[0035] The rubber pad 19 can increase the friction between the limit rod 16 and the connecting plate 12, further restricting the rotation of the connecting plate 12 and ensuring the stability of the processing.

[0036] like Figure 1 As shown, it also includes a finished product placement rack 20, which is placed on the base 1 and has two long rods.

[0037] like Figure 1 As shown, it also includes casters 21, and four casters 21 are installed at the bottom of the finished product placement rack 20.

[0038] The finished product placement rack 20 is used to place finished products. It has a simple design and is easy to use. It is suitable for placing ring-shaped products. With the casters 21, it is easy to move the finished products and transport them to the pot lid assembly area to complete the subsequent steps.

[0039] like Figure 1 As shown, it also includes a protective ring 22, which is sleeved on the outer side of the rotating ring 8.

[0040] The protective ring 22 has a certain degree of elasticity. When the worker's leg comes into contact with the rotating ring 8, the protective ring 22 can act as a buffer to protect the worker's body safety.

[0041] During operation, two operators sit at two separate workstations 2, removing metal rings from the housing 141 of the feeding assembly 14 and placing them onto the placement disc 13 of the feeding assembly. The system is activated via controller 101, with the first motor 6 driving gear 7 to mesh with the gear ring 4, rotating the rotating ring 8 and the feeding assembly on it. When the rotation reaches a specific position, i.e., when the placement disc 13 is below the crimping machine 102, the electric push rod of the crimping machine 102 pushes the rolling wheel downwards. Simultaneously, the second motor 10 starts, driving the connecting disc 12 and the placement disc 13 to rotate via the toggle block 11, causing the metal ring to be crimped under the pressure of the rolling wheel. After crimping, the crimping machine 102 resets, and the rotating ring 8 continues to rotate, carrying the crimped metal ring to the opposite workstation 2 for the operator to remove and place a new metal ring. This achieves simultaneous material handling and feeding, and keeps the material away from the crimping machine 102, ensuring operational safety. In addition, the feeding assembly 14 drives the moving plate 143 to slide up and down via the electric slide rail 142, making it easy for the operator to pick up the metal ring. During the rotation of the rotating ring 8, the limiting rod 16 cooperates with the roller 18 and the return spring 17 to limit the rotation of the connecting plate 12 in the non-rolled edge area, ensuring a stable fit between the toggle block 11 and the connecting plate 12. The rubber pad 19 further enhances the limiting effect. The finished product placement rack 20 is used to store finished products, and its bottom casters 21 facilitate movement. The protective ring 22 on the outside of the rotating ring 8 provides a safety barrier to protect workers from accidental injury.
