Description

Technical Field

[0001] The utility model relates to the technical field of foam production equipment, in particular to a sheet material slicing machine. Background Art

[0002] EVA is a copolymer of ethylene and acetic acid, and its Chinese chemical name is ethylene-vinyl acetate copolymer (ethylene-vinyl acetate copolymer). EVA has a wide range of applications, and is often used in life and industry, as well as in the production of shoe soles and various fitness mats and shock-absorbing pads. When processing EVA foam into finished products such as fitness mats, the foam needs to be cut.

[0003] Publication No. CN218398228U discloses a slicer for EVA foam production, including an outer protective box, one end of the outer protective box surface is installed with a motor 1, the output end of the motor 1 is installed with a transport roller, a foam board is arranged between the transport rollers, a control panel is installed on one side of the motor 1, and an external plate is installed at one end of the outer protective box. Cylinder 2 retracts the slicer, so that the telescopic rod is retracted and threadedly connected with the connecting ring to facilitate limiting the stability and trajectory of the slicer during the descent process. The setting of the slicer can be used to slice the foam board at right angles. Afterwards, when slicing the rubber pad or fitness mat with rounded corners, cylinder 1 drives the mounting plate to descend inside the slide slot, and motor 2 drives the circular slicer to adjust the angle of the rounded corner to align the setting, and the slice is dropped. The contact surface between the slicer and the circular slice is set horizontally. However, the prior art still has disadvantages:

[0004] 1. The prior art controls the motor to start and drive the transport roller to rotate at a certain frequency, and transports the foam sheet to the external plate on one side. When the foam is transported, there is a lack of fixation on both sides of the foam, which easily causes the foam to be transported offset during transportation, resulting in inconsistent sizes of the cut sheets.

[0005] 2. The prior art cannot adjust the distance between the two transport rollers during transportation, and cannot be applied to the transportation of foams of different thicknesses. When transporting thicker foams, the foams will be deformed due to extrusion, resulting in lower applicability. Utility Model Content
