Description

Technical Field

[0001] This utility model relates to the field of foam production technology, specifically to a silicone foam die-cutting device. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam is divided into PU foam, antistatic foam, conductive foam, etc. Foam has the characteristics of excellent elasticity and light weight. Foam is often used for the protection of objects. Therefore, it is necessary to cut rolls of foam into specifications that are compatible with the appearance and shape of the protected items. Foam slitting devices in related technologies usually include a die-cutting table and a feeding module, a die-cutting cutter, and a receiving module arranged sequentially on the die-cutting table. The feeding module feeds the foam roll, the die-cutting cutter cuts the foam, and finally the receiving module rewinds the foam to complete the die-cutting process.

[0003] In most existing silicone foam die-cutting equipment, the die-cutting blades cut the foam at a high frequency during the die-cutting process, which easily attracts the residue generated during the cutting of silicone foam. This not only affects the die-cutting blades, but also has a significant impact on the next die-cutting operation. It often requires frequent manual replacement and cleaning of residue, which is time-consuming and labor-intensive. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a silicone foam die-cutting device to solve the technical problem that the high-frequency cutting of foam by the die-cutting blade easily absorbs the residue generated during the cutting of silicone foam, which not only affects the die-cutting blade, but also has a significant impact on the next die-cutting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicone foam die-cutting device, comprising a base, two sets of fixed frames at the top of the base, each set of fixed frames having a moving mechanism inside, a die-cutting mechanism between the two sets of moving mechanisms, a heating plate mechanism fixedly connected inside the die-cutting mechanism, a die-cutting cutter inside the heating plate mechanism, two sets of scrapers cooperating with the die-cutting cutter at the bottom of the heating plate mechanism, a collecting plate located on one side of the heating plate mechanism at the bottom of the two sets of scrapers, an air duct inside the collecting plate, and an absorption mechanism movably connected to one end of the air duct.

[0006] By adopting the above technical solution, the die-cutting mechanism combines two sets of scrapers, a second spring, and a hydraulic telescopic rod to scrape away residue from both sides as the die-cutting blade moves up and down. This reduces the impact of foam residue on the die-cutting blade and extends its lifespan. Simultaneously, the die-cutting mechanism incorporates a collection plate, air duct, and absorption mechanism to collect the scraped residue. Furthermore, two sets of linkage mechanisms control the collection plate and the die-cutting blade to reciprocate in a staggered manner, thus automatically collecting the foam residue.

[0007] Furthermore, both sides of the die-cutting cutter are fixedly connected with limiting blocks extending to the outside of the heating plate mechanism. The heating plate mechanism has a limiting groove inside that cooperates with the limiting blocks. The top of each of the two sets of limiting blocks is movably connected with a hydraulic telescopic rod. The ends of each of the two sets of hydraulic telescopic rods are provided with hydraulic ports that connect to external pipelines.

[0008] By adopting the above technical solution, the structure in which limiting blocks extending to the outside of the heating plate mechanism are fixedly connected to both sides of the die-cutting cutter, and the structure in which limiting grooves that cooperate with the limiting blocks are opened inside the heating plate mechanism, the function of limiting the movement of the die-cutting cutter is achieved. At the same time, the structure in which hydraulic telescopic rods are movably connected to the top of the limiting blocks, the function of driving the die-cutting cutter to move up and down is achieved.

[0009] Furthermore, both sets of scrapers are movably connected to the die-cutting mechanism via a fixed shaft, and two sets of second springs are movably connected between the two sets of scrapers, with the two sets of second springs serving to keep the scrapers tightly attached to the surface of the die-cutting tool.

[0010] By adopting the above technical solution, the structure in which the scrapers are movably connected to the die-cutting mechanism through a fixed shaft and the structure in which two sets of second springs are movably connected between the scrapers achieves the effect of scraping residue off both sides of the die-cutting tool by the two sets of scrapers, while the second springs set between the two sets of scrapers make the two sets of scrapers stick tightly to the surface of the die-cutting tool.

[0011] Furthermore, the collecting plate and the die-cutting mechanism are movably connected via a fixed shaft, and a linkage mechanism is movably connected between the collecting plate and the limiting block. The linkage mechanism consists of a first telescopic column, a second telescopic column, a rotating shaft, a first spring, and a limiting plate. The second telescopic column is provided inside the first telescopic column, and a first spring is provided inside the first telescopic column located outside the second telescopic column. A limiting plate that cooperates with the first spring is fixedly connected to the outer wall of the second telescopic column. A rotating shaft is provided at the ends of both the first and second telescopic columns.

[0012] By adopting the above technical solution, the limiting block drives the collecting plate to rotate through the second telescopic column and the first telescopic column. When the collecting plate rotates to the appropriate position, the die-cutting cutter has not yet completed the die-cutting. The die-cutting cutter continues to move downward. At this time, the second telescopic column squeezes the first spring through the limiting plate, thereby further extending the length of the linkage mechanism. When the die-cutting cutter performs the reset movement, the first spring drives the second telescopic column to reset through the limiting plate, thereby restoring the linkage mechanism to the default length. At the same time, the collecting plate performs the reset movement.

[0013] Furthermore, the collecting plate has a collecting cavity that cooperates with the scraper, and a cavity that cooperates with the air duct. The air duct is made of soft rubber material, and the elastic force of the first spring is greater than the weight of the collecting plate itself.

[0014] By adopting the above technical solution, foam residue falls into the cavity inside the collection plate. At this time, the absorption mechanism absorbs and discharges the foam residue inside the collection plate through the air duct, thereby completing the function of cleaning the residue on the surface of the die-cutting tool.

[0015] Furthermore, the base has multiple sets of lifting support columns at its bottom and a die-cutting plate that cooperates with the die-cutting tool at its top. Both sets of fixed frames have sliding grooves that cooperate with the moving mechanism inside.

[0016] By adopting the above technical solution, the moving mechanism drives the die-cutting mechanism to move to the designated position along the slide groove opened inside the fixed frame.

[0017] In summary, this utility model has the following beneficial effects: By combining two sets of scrapers, a second spring, and a hydraulic telescopic rod inside the die-cutting mechanism, the die-cutting tool scrapes away residue from both sides as it moves up and down, thereby reducing the impact of foam residue on the die-cutting tool and extending its service life. Simultaneously, by combining a collecting plate, air duct, and absorption mechanism inside the die-cutting mechanism, the scraped residue is collected. Furthermore, two sets of linkage mechanisms control the collecting plate and the die-cutting tool to reciprocate in a staggered manner, thus automatically collecting foam residue.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A silicone foam die-cutting device, such as Figure 1-7As shown, the device includes a base 1, with two sets of fixed brackets 2 at the top of the base 1. Each set of fixed brackets 2 contains a moving mechanism 3. A die-cutting mechanism 4 is positioned between the two sets of moving mechanisms 3. A heating plate mechanism 5 is fixedly connected inside the die-cutting mechanism 4. A die-cutting cutter 15 is installed inside the heating plate mechanism 5. Two sets of scrapers 7 that cooperate with the die-cutting cutter 15 are located at the bottom of the heating plate mechanism 5. A collection plate 6 located on one side of the heating plate mechanism 5 is installed at the bottom of the two sets of scrapers 7. An air duct 9 is installed inside the collection plate 6. One end of the air duct 9 is movably connected to an absorption mechanism 10. When the die-cutting cutter 15 is open... When the initial rising and resetting mechanism and the collecting plate 6 rotate and reset, the two sets of scrapers 7 scrape the residue from both sides of the die-cutting tool 15. At the same time, the second spring 17 between the two sets of scrapers 7 keeps the two sets of scrapers 7 in close contact with the surface of the die-cutting tool 15. When the scrapers 7 begin to contact the foam residue, the collecting plate 6 just completes its reset and collects the foam residue. The foam residue falls into the cavity inside the collecting plate 6. At this time, the absorption mechanism 10 absorbs and discharges the foam residue inside the collecting plate 6 through the air duct 9, thereby completing the cleaning of the residue on the surface of the die-cutting tool 15.

[0029] Please see Figure 4 , Figure 6 and Figure 7 The collecting plate 6 is movably connected to the die-cutting mechanism 4 via a fixed shaft 8. A linkage mechanism 16 is movably connected between the collecting plate 6 and the limiting block 13. The linkage mechanism 16 consists of a first telescopic column 1601, a second telescopic column 1602, a rotating shaft 1603, a first spring 1604, and a limiting plate 1605. The second telescopic column 1602 is installed inside the first telescopic column 1601. The first spring 1604 is located outside the second telescopic column 1602 inside the first telescopic column 1601. A limiting plate 1605 that cooperates with the first spring 1604 is fixedly connected to the outer wall of the second telescopic column 1602. Both the first telescopic column 1601 and the second telescopic column 1602 are provided with... The rotating shaft 1603, specifically the limiting block 13, drives the collecting plate 6 to rotate through the second telescopic column 1602 and the first telescopic column 1601. When the collecting plate 6 rotates to the appropriate position, the die-cutting cutter 15 has not yet completed the die-cutting and continues to move downward. At this time, the second telescopic column 1602 squeezes the first spring 1604 through the limiting plate 1605, thereby further extending the length of the linkage mechanism 16. When the die-cutting cutter 15 performs the reset movement, the first spring 1604 drives the second telescopic column 1602 to reset through the limiting plate 1605, thereby restoring the linkage mechanism 16 to its default length. At the same time, the collecting plate 6 performs the reset movement.

[0030] Please see Figure 1 and Figure 5Both sides of the die-cutting cutter 15 are fixedly connected to limiting blocks 13 extending to the outside of the heating plate mechanism 5. The heating plate mechanism 5 has a limiting groove 14 that cooperates with the limiting blocks 13. The top of each of the two sets of limiting blocks 13 is movably connected to a hydraulic telescopic rod 11. The ends of the two sets of hydraulic telescopic rods 11 are provided with hydraulic pipe ports 12 that connect to external pipes. The die-cutting mechanism 4 is driven by the moving mechanism 3 to move along the slide groove 20 opened inside the fixed frame 2. When the die-cutting mechanism 4 moves to the designated position, the two sets of hydraulic telescopic rods 11 inside the die-cutting mechanism 4 squeeze the limiting blocks 13, thereby causing the die-cutting cutter 15 to move downward.

[0031] The working principle of this utility model is as follows: When in use, the power is turned on and the user places the silicone foam on the die-cutting plate 19. The moving mechanism 3 drives the die-cutting mechanism 4 to move along the slide groove 20 opened inside the fixed frame 2. When the die-cutting mechanism 4 moves to the designated position, the two sets of hydraulic telescopic rods 11 inside the die-cutting mechanism 4 squeeze the limiting block 13, thereby causing the die-cutting cutter 15 to move downward.

[0032] As the die-cutting cutter 15 moves downward, the linkage mechanism 16 on one side of the limiting block 13 drives the collecting plate 6 to rotate along the fixed shaft 8, thereby causing the collecting plate 6 and the die-cutting cutter 15 to move out of alignment, ultimately allowing the die-cutting cutter 15 to die-cut the silicone foam on the die-cutting plate 19.

[0033] Specifically, the limiting block 13 drives the collecting plate 6 to rotate through the second telescopic column 1602 and the first telescopic column 1601. When the collecting plate 6 rotates to the appropriate position, the die-cutting cutter 15 has not yet completed the die-cutting. The die-cutting cutter 15 continues to move downward. At this time, the second telescopic column 1602 squeezes the first spring 1604 through the limiting plate 1605, thereby further extending the length of the linkage mechanism 16. When the die-cutting cutter 15 performs the reset movement, the first spring 1604 drives the second telescopic column 1602 to reset through the limiting plate 1605, thereby restoring the linkage mechanism 16 to the default length. At the same time, the collecting plate 6 performs the reset movement.

[0034] During use, when the die-cutting blade 15 begins to rise and reset, and the collecting plate 6 rotates and resets, the two sets of scrapers 7 scrape off the residue on both sides of the die-cutting blade 15. At the same time, the second spring 17 between the two sets of scrapers 7 keeps the two sets of scrapers 7 in close contact with the surface of the die-cutting blade 15. When the scrapers 7 begin to contact the foam residue, the collecting plate 6 just completes its reset and collects the foam residue.

[0035] Specifically, foam residue falls into the cavity inside the collecting plate 6. At this time, the absorption mechanism 10 absorbs and discharges the foam residue inside the collecting plate 6 through the air duct 9, thereby completing the function of cleaning the residue on the surface of the die-cutting tool 15.
