Description

Technical Field

[0001] This utility model relates to the field of soft foam die-cutting technology, specifically a soft foam die-cutting device with an anti-stick blade. Background Technology

[0002] Foam die-cutting equipment is a device used to cut foam into specific shapes. It is widely used in industries such as packaging, electronics, and automobiles. However, during the die-cutting process, foam material may stick to the die, causing the die-cutting tool to adhere to the foam, affecting cutting accuracy and production efficiency.

[0003] A search of Chinese patent CN219726560U reveals a foam die-cutting machine, comprising a die-cutting base for support. Nine sets of die-cutting guide grooves are evenly spaced near the center of the inner end face of the die-cutting base, and two sets of guide rollers are located at both ends of the inner end face. A support bracket is fixedly installed at the center of the upper end face of the die-cutting base. This invention, through the die-cutting device, allows the die-cutting cylinder to drive the guide slide downwards via a guide shaft during foam die-cutting. This guide slide then simultaneously drives two sets of positioning pressure plates and the die-cutting mold downwards. The two positioning pressure plates first contact the foam, and simultaneously, the elastic tension of the spring retainer pre-limits the foam being die-cut by the die-cutting mold, preventing displacement of the foam during die-cutting. Simultaneously, the die-cutting mold can quickly die-cut the foam through the die-cutting guide grooves, and the die-cut foam can be automatically exported through the die-cutting guide grooves, improving the automation level of the foam die-cutting equipment.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Due to the high friction of the soft foam itself, it is easy to stick to the die-cutting device, which affects the die-cutting work of the soft foam and makes it inconvenient to pick up the soft foam. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-stick soft foam die-cutting device.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a soft foam die-cutting device with an anti-sticking blade, including a mounting plate, a mold fixedly mounted on the mounting plate, a frame plate fixedly mounted on the mounting plate, a hydraulic cylinder provided on the frame plate, a movable plate fixedly mounted on the telescopic end of the hydraulic cylinder, a cutter adapted to the mold fixedly mounted on the movable plate, a support mechanism provided on the movable plate, the support mechanism including multiple fixed sleeves fixedly mounted on the movable plate, a first spring connected to the inner wall of each fixed sleeve, and a telescopic rod slidably connected to the end of the first spring;

[0008] The cutting tool is provided with a pushing mechanism, which includes an inner sleeve fixedly installed on the cutting tool. A second spring is connected to the inner wall of the inner sleeve, and a telescopic block that is slidably connected to the inner sleeve is connected to the end of the second spring.

[0009] The mounting plate is provided with a blowing mechanism, which includes two sets of piston assemblies disposed between the mounting plate and the movable plate, and an air blowing assembly is disposed between the two sets of piston assemblies.

[0010] Furthermore, the mold is fixedly mounted with a plurality of support rods that are slidably connected to the movable plate.

[0011] Furthermore, a soft foam body is placed on the mold.

[0012] Furthermore, the piston assembly includes a piston housing fixedly mounted on the mounting plate, and an inlet valve is provided on the piston housing.

[0013] Furthermore, the piston assembly also includes a connecting rod fixedly mounted on the movable plate, and the connecting rod is slidably connected to the frame plate and the piston shell. A piston plate that is slidably connected to the piston shell is fixedly mounted at the end of the connecting rod, and a delivery pipe is fixedly mounted on the piston shell.

[0014] Furthermore, the air blowing assembly includes an air collecting shell fixedly installed between the two delivery pipes, and a pressure valve is provided on the air collecting shell.

[0015] Furthermore, the air blowing assembly also includes a first air outlet and a second air outlet fixedly installed on the pressure valve.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] In this invention, multiple telescopic rods work in conjunction with a mold to support the soft foam body, thereby enabling the die-cutting of the soft foam body. After die-cutting, the second spring uses its own elasticity to support the telescopic block, allowing the telescopic block to support the die-cut soft foam body. When the hydraulic cylinder drives the movable plate to move, the piston assembly can deliver air to the inside of the air collection shell. When the pressure in the air collection shell exceeds the threshold of the pressure valve, the gas in the air collection shell is ejected through the first air outlet and the second air outlet, respectively, blowing the soft foam body and the residue, allowing the soft foam body to detach from the cutter and mold, and facilitating the unloading of the soft foam body and the residue.

While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0026] like Figures 1 to 5 As shown, an embodiment of this utility model provides a soft foam die-cutting device with an anti-stick blade, including a mounting plate 1, a mold 2 fixedly mounted on the mounting plate 1, a frame plate 4 fixedly mounted on the mounting plate 1, a hydraulic cylinder 5 fixedly mounted on the frame plate 4, a movable plate 6 fixedly mounted on the telescopic end of the hydraulic cylinder 5, a cutter 7 adapted to the mold 2 fixedly mounted on the movable plate 6, a plurality of support rods 3 slidably connected to the movable plate 6 fixedly mounted on the mold 2, and a soft foam body 8 placed on the mold 2.

[0027] In this embodiment of the utility model, the mounting plate 1 is fixed to the external machine body using mounting parts. The operator places the soft foam body 8 on the mold 2 and controls the extension end of the hydraulic cylinder 5 to extend, so that the extension end of the hydraulic cylinder 5 drives the cutter 7 to move into the inner side of the mold 2 through the movable plate 6. The movable plate 6 moves along multiple support rods 3, so that the cutter 7 cooperates with the mold 2 to perform die-cutting work on the soft foam body 8. After die-cutting, the extension end of the hydraulic cylinder 5 retracts to the fixed end, driving the movable plate 6 and the cutter 7 to reset and move.

[0028] Figures 1 to 5 As shown, a support mechanism is provided on the movable plate 6. The support mechanism includes multiple fixed sleeves 9 fixedly installed on the movable plate 6. A first spring 10 is connected to the inner wall of each fixed sleeve 9. The end of the first spring 10 is connected to a telescopic rod 11 that is slidably connected to the fixed sleeve 9. A pushing mechanism is provided on the cutter 7. The pushing mechanism includes an inner sleeve 12 fixedly installed on the cutter 7. A second spring 13 is connected to the inner wall of the inner sleeve 12. The end of the second spring 13 is connected to a telescopic block 14 that is slidably connected to the inner sleeve 12.

[0029] In this embodiment of the utility model, the first spring 10 can support the telescopic rod 11 with its own elasticity. The multiple telescopic rods 11, together with the mold 2, support the soft foam body 8, thereby enabling the die-cutting of the soft foam body 8. After die-cutting, the second spring 13 can support the telescopic block 14 with its own elasticity, so that the telescopic block 14 can support the die-cut soft foam body 8, thereby preventing the soft foam body 8 and the residual material from sticking to the mold 2 and the cutter 7 respectively.

[0030] Figures 1 to 5As shown, a blowing mechanism is provided on the mounting plate 1. The blowing mechanism includes two sets of piston assemblies disposed between the mounting plate 1 and the movable plate 6. An air blowing assembly is provided between the two sets of piston assemblies. The piston assembly includes a piston shell 15 fixedly mounted on the mounting plate 1. An inlet valve 16 is provided on the piston shell 15. The piston assembly also includes a connecting rod 17 fixedly mounted on the movable plate 6. The connecting rod 17 is slidably connected to the frame plate 4 and the piston shell 15. A piston plate 18 slidably connected to the piston shell 15 is fixedly mounted at the end of the connecting rod 17. A delivery pipe 19 is fixedly mounted on the piston shell 15. The air blowing assembly includes an air collecting shell 20 fixedly mounted between the two delivery pipes 19. A pressure valve 21 is provided on the air collecting shell 20. The air blowing assembly also includes a first air outlet 22 and a second air outlet 23 fixedly mounted on the pressure valve 21.

[0031] In this embodiment of the utility model, when the hydraulic cylinder 5 drives the movable plate 6 to move downward, the movable plate 6 drives the piston plate 18 to move downward along the inner side of the piston shell 15 through the connecting rod 17, so that the piston plate 18 draws outside air into the inner side of the piston shell 15 through the inlet valve 16. When the hydraulic cylinder 5 drives the movable plate 6 to move back to its original position, the piston plate 18 compresses the air in the piston shell 15, so that the air moves into the inner side of the gas collecting shell 20 through the conveying pipe 19. When the pressure in the gas collecting shell 20 exceeds the threshold of the pressure valve 21, the gas in the gas collecting shell 20 is ejected through the first air outlet 22 and the second air outlet 23 respectively, blowing the soft foam body 8 and the residue respectively, so that the soft foam body 8 can be separated from the cutter 7 and the mold 2, and it is convenient to unload the soft foam body 8 and the residue.

[0032] Working principle: The operator places the soft foam body 8 on the mold 2 and controls the extension end of the hydraulic cylinder 5 to extend, so that the extension end of the hydraulic cylinder 5 drives the cutter 7 to move into the inside of the mold 2 through the movable plate 6. The movable plate 6 moves along multiple support rods 3, so that the cutter 7 cooperates with the mold 2 to perform die-cutting work on the soft foam body 8. Multiple extension rods 11 cooperate with the mold 2 to abut and support the soft foam body 8, and perform die-cutting work on the soft foam body 8. After die-cutting, the second spring 13 can use its own elasticity to support the extension block 14, so that the extension block 14 can support the die-cut soft foam body 8. After die-cutting, the extension end of the hydraulic cylinder 5 retracts to the fixed end, driving the movable plate 6 and the cutter 7 to reset and move.

[0033] When the hydraulic cylinder 5 drives the movable plate 6 to move downward, the movable plate 6 drives the piston plate 18 to move downward along the inner side of the piston shell 15 through the connecting rod 17, so that the piston plate 18 draws outside air into the inner side of the piston shell 15 through the inlet valve 16. When the hydraulic cylinder 5 drives the movable plate 6 to move back to its original position, the piston plate 18 compresses the air in the piston shell 15, so that the air moves into the inner side of the air collecting shell 20 through the conveying pipe 19. When the pressure in the air collecting shell 20 exceeds the threshold of the pressure valve 21, the gas in the air collecting shell 20 is ejected through the first air outlet 22 and the second air outlet 23 respectively, blowing the soft foam body 8 and the residue respectively, so that the soft foam body 8 is separated from the cutter 7 and the mold 2, and the soft foam body 8 and the residue are unloaded.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
