Description

Technical Field

[0001] The utility model relates to the technical field of slitting devices, in particular to a silicone foot pad slitting device. Background Art

[0002] Silicone foot pads are a common household item. They have characteristics such as softness, wear resistance, anti-slip, and sound insulation, and can be used for the protection and shock absorption of objects such as the ground, desktop, or chair legs. When producing silicone foot pads, a slitting device is required to slit the produced large silicone foot pads into small pieces.

[0003] In order to improve the efficiency of slitting silicone foot pads, many improvements have been made to the slitting device for silicone foot pads in the prior art. For example, the patent with the publication number CN219190369U discloses a slitting device for silicone foot pads, which includes a material bin mechanism, a cutting mechanism, and a material taking manipulator. The material bin mechanism includes a storage box with a storage groove, a loading plate, and a first lifting cylinder. The material taking manipulator includes a longitudinal linear driving mechanism, a transverse linear driving mechanism, and a suction cup assembly. The cutting mechanism includes a conveyor belt and a slitting mechanism. The longitudinal linear driving mechanism and the transverse linear driving mechanism drive the suction cup assembly to move up and down and left and right respectively. The suction cup assembly picks up the topmost silicone sheet from the side of the storage box and places it on the conveyor belt. When the silicone sheet is conveyed by the conveyor belt and passes through the slitting mechanism, the slitting mechanism performs a cutting operation on the silicone sheet. The first lifting cylinder drives the loading plate to rise to keep the topmost silicone sheet at the same height, ensuring that the material taking manipulator can smoothly pick up the silicone sheet from the storage box and ensuring the continuous progress of the production process, and realizing the automation of feeding and cutting.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the silicone sheet is conveyed through a conveyor belt, and the silicone sheet is slit by a rotating slitting knife when it is being conveyed. In reality, since the silicone sheet just produced is large, while the size of the finished silicone foot pad is small, it is necessary to perform horizontal and vertical slitting on the large silicone sheet to slit the large-area silicone sheet into smaller sizes. However, the above comparative document can only slit the silicone sheet into long strips, and it is necessary to slit the long-strip silicone sheet again later, which reduces the efficiency of slitting the silicone sheet. Therefore, it is urgent in this field to improve the slitting device for silicone foot pads to solve the defects of the prior art. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a slitting device for silicone foot pads, which can complete the horizontal and vertical slitting of the silicone sheet by one-time conveying of the silicone sheet, improving the slitting efficiency.

[0031] Specific implementation method in this embodiment: When it is necessary to cut the produced silicone sheet, place the silicone sheet on the conveyor belt 3 and start the driving motor 4. The output end of the driving motor 4 drives the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the driving roller 2 to rotate, and the driving roller 2 drives the conveyor belt 3 to rotate, thereby conveying the silicone sheet. When the driving motor 4 is started, it simultaneously drives the third rotating shaft 9, the auxiliary pressing roller 6 and the second rotating shaft 7 to rotate.

When the silicone sheet cut into long strips moves to the end of the conveyor belt 3, the rotation of the second rotating shaft 7 drives the strip cutter 8 to move up and down, thereby cutting the long strip-shaped silicone sheet into several small pieces. Through one-time conveying of the silicone sheet, the horizontal and vertical cutting of the silicone sheet can be completed, improving the cutting efficiency.
