Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to a leveling mechanism for aluminum foil die-cutting. Background Technology

[0002] Die-cutting machines, also known as CNC punching machines, are used for die-cutting, creasing, and hot stamping of products. During die-cutting, the machine uses a die-cutting blade to cut the product into a specific shape. For thin aluminum foil products, the cutting force of the die-cutting blade during the die-cutting process may cause downward bending burrs or other defects at the cut edges, affecting the product's processing quality. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a leveling mechanism for aluminum foil die-cutting, which can level the edges of the die-cut product to ensure the die-cutting quality of the product.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a leveling mechanism for aluminum foil die-cutting, which is disposed on the rear side of the die-cutting equipment along the product conveying direction; including...

[0005] The machine is equipped with a receiving base plate for receiving product tapes;

[0006] A leveling assembly is mounted on the machine base and includes a leveling drive, a mounting plate, and a leveling template. The mounting plate can be raised and lowered under the action of the leveling drive. The leveling template is mounted on the mounting plate and has a plurality of mold grooves at its lower end facing the receiving substrate and corresponding one-to-one with the number of products in a single row on the product strip. The mold groove includes a groove body with an opening facing downward. The groove body has a bottom wall and side walls arranged around the edge of the bottom wall. The bottom wall is arranged in a horizontal direction and the side walls are arranged in a vertical direction.

[0007] When the mounting plate moves downward under the action of the leveling drive, the mold groove can move towards the receiving substrate so that the product on the receiving substrate enters the corresponding groove until the upper surface of the product abuts against the bottom wall of the groove and the side wall of the product abuts against the side wall of the groove.

[0008] When the product strip moves onto the receiving substrate, the leveling template can be aligned with the product strip located on the receiving substrate. Then, the mounting plate is driven to move down by the leveling drive component, so that the leveling template and the mold groove move down synchronously, thereby enabling the mold groove to be aligned with the individual product on the product strip, and the individual product is leveled by the bottom wall and side wall of the groove.

[0009] The beneficial effects of this utility model of a leveling mechanism for aluminum foil die-cutting are as follows:

[0010] A leveling mechanism is installed at the rear of the die-cutting equipment to level the die-cut products and ensure their flatness. The receiving substrate can receive the product strip conveyed to the leveling mechanism. The leveling drive unit drives the leveling template and the die groove to move synchronously, so that the groove in the die groove contacts the product on the product strip by pressing down. The flatness of the bottom wall and side wall of the groove is used to apply pressure to the top surface and edge of the product to ensure the flatness of the top surface and edge of the product.

[0011] Furthermore, the mold groove includes a lower protrusion formed around the groove body, the lower protrusion being lower than the lower end face of the leveling template. When the leveling template moves downward, the lower protrusion can contact the product strip before the leveling template, thereby ensuring that the corresponding product on the product strip can enter the area of ​​the corresponding groove body.

[0012] Furthermore, the lower protrusion slopes downwards gradually from the direction closest to the groove body towards the direction furthest away from the groove body. This design ensures that the side of the lower protrusion furthest from the groove body contacts the product conveyor belt first, providing sufficient space for individual products to enter their respective grooves and preventing product misalignment that could prevent accurate entry. The gradual tilting of the lower protrusion also guides the product, ensuring its smooth entry into the corresponding groove.

[0013] Furthermore, the receiving substrate is provided with a first edge-pressing assembly, which includes edge-pressing plates symmetrically arranged on both sides of the product strip along a direction perpendicular to the product conveying direction; the minimum distance between a pair of edge-pressing plates along the direction perpendicular to the product conveying direction is greater than the size of the leveling template. The edge-pressing plates limit the edge of the product strip to avoid deviation during conveying, thus facilitating accurate entry of the product into the corresponding groove; and limiting the size of the edge-pressing plates and the leveling template prevents the edge-pressing plates from interfering with the downward movement of the leveling template.

[0014] Furthermore, the system also includes a feeding assembly arranged along one side of the machine along the product conveying direction. The feeding assembly includes a pair of frames, each frame sharing a common conveyor roller for receiving the product strip. The conveyor roller is connected to a conveyor motor mounted on the frame. The conveyor motor drives the conveyor roller, thus facilitating the conveying of the product strip.

[0015] Furthermore, a curved feed plate is connected to both of the aforementioned frames. The curved feed plate is located on the side of the frame away from the machine platform, and one end of the curved feed plate smoothly transitions to the upper surface of the conveyor roller. The curved feed plate facilitates the feeding action of the product strip.

[0016] Furthermore, the feeding assembly also includes a second edge-pressing assembly, which includes a roller and pressure rollers. The roller is located above the conveyor roller, and its two ends are respectively mounted on the frame via adjusting components. Two pressure rollers are provided and coaxially mounted on the roller. The two pressure rollers can respectively abut against the two sides of the product strip to ensure the stability of the product strip conveying.

[0017] Furthermore, the adjusting component includes a sliding plate and a screw. The sliding plate is slidably mounted on the frame and has mounting holes for mounting the roller. The screw passes vertically through the frame and is threadedly connected to the sliding plate. The adjusting component facilitates the adjustment of the roller height, thereby allowing the height of the pressure roller to be adjusted according to the thickness of the product strip.

[0018] Furthermore, the frame is provided with a sliding groove for the sliding plate to move, thereby limiting the sliding range of the sliding plate.

[0019] Furthermore, the leveling assembly also includes a fixed frame mounted on the machine platform, on which the leveling drive component is mounted. Attached Figure Description

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0034] Example

[0035] See appendix Figure 1-5 As shown, a leveling mechanism for aluminum foil die-cutting according to this utility model is arranged on the rear side of the die-cutting equipment along the product conveying direction. The leveling mechanism includes a machine base 1 and a leveling assembly 2. The machine base 1 is provided with a receiving base plate 11 for receiving the product strip 3. The leveling assembly 2 is arranged on the machine base 1 and includes a leveling drive 21, a mounting plate 22, and a leveling template 23. The mounting plate 22 can be raised and lowered under the action of the leveling drive 21. The leveling template 23 is mounted on the mounting plate 22 and has a plurality of die grooves 24 at its lower end facing the receiving base plate 11 and corresponding at least one-to-one with the number of products in a single row on the product strip 3. The die grooves 24 include a groove body with an opening facing downward. The groove body has a bottom wall 241 and a side wall 242 arranged around the edge of the bottom wall 241. The bottom wall 241 is arranged in a horizontal direction and the side wall 242 is arranged in a vertical direction. When the mounting plate 22 moves downward under the action of the leveling drive 21, the mold groove 24 can move towards the receiving substrate 11 so that the product 31 on the receiving substrate 11 enters the corresponding groove until the upper end surface of the product 31 abuts against the bottom wall 241 of the groove and the side wall of the product 31 abuts against the side wall 242 of the groove.

[0036] When the product strip 3 moves onto the receiving substrate 11, the leveling template 23 can be aligned with the product strip 3 located on the receiving substrate 11. Then, the mounting plate 22 is driven to move down by the leveling drive 21 so that the leveling template 23 and the mold groove 24 move down synchronously, thereby enabling the mold groove 24 to be aligned with the individual product 31 on the product strip 3, and to perform a leveling operation on the individual product 31 through the bottom wall 241 and side wall 242 of the groove.

[0037] It should be noted that in practical applications, aluminum foil products are usually produced in the form of strips. These strips are transported to different workstations via a conveyor mechanism for processing. For example, at the die-cutting station, die-cutting equipment cuts the aluminum foil from the strip into multiple independent products. Figure 2 As shown, the product strip 3 has multiple rows of products 31, with four independent products 31 in each row. Therefore, to improve efficiency, when the product strip 3 moves to the receiving substrate 11 of the leveling mechanism, the leveling component 2 also needs to perform a synchronous leveling operation on the single row of products 31 on the product strip 3. Of course, multiple rows of products 31 on the product strip 3 can also be leveled synchronously simultaneously according to actual needs. In this case, only the number of mold slots 24 on the leveling template 23 needs to be adjusted.

[0038] In some embodiments, see Appendix Figure 4-5 As shown, the mold groove 24 includes a lower protrusion 243 formed around the groove body, which is lower than the lower end face of the leveling template 23. When the leveling template 23 moves downward, the lower protrusion 243 can contact the product strip 3 before the leveling template 23, thereby ensuring that the corresponding product 31 on the product strip 3 can enter the corresponding groove body. Furthermore, the lower protrusion 243 gradually slopes downward from the direction close to the groove body to the direction away from the groove body. This arrangement ensures that the side of the lower protrusion 243 away from the groove body contacts the product strip 3 first, reserving sufficient space for a single product 31 to enter the corresponding groove body, preventing the product from being unable to accurately enter the groove body due to product position deviation. Moreover, the gradual tilting of the lower protrusion 243 can guide the product 31, so that the product 31 can smoothly enter the corresponding groove body.

[0039] It should be noted that the highest point of the lower protrusion 243 must be lower than the lower end surface of the leveling template 23, and the vertical distance between the bottom wall 241 of the groove and the lowest point of the lower protrusion 243 should not be greater than the thickness of the product 31, so as to ensure that the upper end surface of the product 31 can abut against the bottom wall 241 of the groove.

[0040] In some embodiments, see Appendix Figure 3As shown, a first edge-pressing assembly is provided on the receiving substrate 11. The first edge-pressing assembly includes edge-pressing plates 4 symmetrically arranged on both sides of the product strip along the direction perpendicular to the product conveying direction. Along the direction perpendicular to the product conveying direction, the minimum distance between a pair of edge-pressing plates 4 is greater than the size of the leveling template 23. The edge-pressing plates 4 limit the edge of the product strip 3 to avoid the deviation problem during the conveying process of the product strip 3, thereby facilitating the accurate entry of the product 31 into the corresponding groove; and by limiting the size of the edge-pressing plates 4 and the leveling template 23, the interference of the edge-pressing plates 4 on the downward movement of the leveling template 23 can be avoided. It should be noted that the edge-pressing plates 4 can only press against the edge of the product strip 3 and will not contact the product 31 on the product strip 3.

[0041] In some embodiments, the leveling assembly 2 further includes a mounting bracket 25 mounted on the machine base 1, and a leveling drive component 21 is mounted on the mounting bracket 25. Exemplarily, the leveling drive component 21 is a cylinder.

[0042] In some embodiments, see Appendix Figure 1 , 6 As shown in Figure 7, along the product conveying direction, a feeding assembly 5 is arranged on the side of the machine base 1 away from the die-cutting equipment. The feeding assembly 5 includes a pair of frames 51, on which a conveyor roller 52 for receiving the product strip 3 is commonly provided. The conveyor roller 52 is connected to a conveyor motor 53 mounted on the frame 51. Furthermore, an arc-shaped feeding plate 54 is also commonly connected to the pair of frames 51. The arc-shaped feeding plate 54 is located on the side of the frame 51 away from the machine base 1, and one end of the arc-shaped feeding plate 54 smoothly transitions to the upper end face of the conveyor roller 52. The arrangement of the arc-shaped feeding plate 54 facilitates the feeding action of the product strip 3.

[0043] In some embodiments, see Appendix Figure 6 As shown, the feeding assembly 5 also includes a second edge pressing assembly, which includes a roller 551 and pressure rollers 552. The roller 551 is located above the conveyor roller 52, and its two ends are respectively mounted on the frame 51 through adjusting components. Two pressure rollers 552 are provided and are coaxially mounted on the roller 551. The two pressure rollers 552 can respectively abut against the two side edges of the product material belt 3 to ensure the stability of the product material belt 3 conveying.

[0044] Furthermore, the adjusting components include a sliding plate 553 and a screw 554. The sliding plate 553 is slidably mounted on the frame 51 and has mounting holes for mounting the roller 551. The screw 554 passes vertically through the frame 51 and is threadedly connected to the sliding plate 553. The adjusting components facilitate the adjustment of the height of the roller 551, thereby allowing the height of the pressure roller 552 to be adjusted according to the thickness of the product strip 3. Correspondingly, the frame 51 has a sliding groove for the sliding plate 553 to move, thereby limiting the sliding range of the sliding plate 553.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
