Description

TECHNICAL FIELD

[0001] The utility model relates to a ground mat cutting technical field especially relates to a kind of for semi-finished product EVA ground mat cutting machine. BACKGROUND

[0002] Ground mat is widely used, such as floor pad, sports ground mat, children's game ground mat and industrial pad, etc., many devices and processes are needed in the conversion from raw material to ground mat, and when cutting EVA ground mat, cutting machine is needed to cut the semi-finished product EVA ground mat into single finished product.

[0003] The material of EVA ground mat is plastic material, which is composed of ethylene and vinyl acetate. When making EVA ground mat, the semi-finished product EVA ground mat that has not completely solidified needs to be further cooled by a cooling roller. After cooling, the semi-finished product EVA ground mat needs to be cut by a cutting device. Cutting refers to the process of cutting the upper and lower layers of the product to match the size of the sample. During EVA ground mat production, cutting equipment is needed to cut the EVA ground mat, so that the EVA ground mat can be cut to the desired size.

[0004] The existing cutting machine has two main problems in actual use: overload and positioning. On the one hand, due to the lack of effective overload protection mechanism, when the driving motor drives the eccentric shaft to rotate, if an abnormal situation occurs, such as material jamming or blade wear, the connecting piece will be overloaded and pressed down due to the excessive rotation force of the ring block. This overload condition not only causes uneven cutting depth and rough edges, affecting product quality, but also damages the key components of the equipment, increases maintenance cost and reduces production efficiency. On the other hand, the existing cutting machine lacks rapid positioning function, which makes the EVA ground mat prone to shift on the cutting table during cutting. This shift will cause deviation in the cutting position, affecting the consistency and quality stability of the product. For example, different batches of ground mat may have size inaccuracies and irregular shapes. In addition, the shift of the ground mat also causes the cutting knife to collide with the edge or other parts of the ground mat, which not only damages the cutting tool but also increases the safety risk.

Therefore, if the ring block 8 is overloaded, the excessive rotation of the ring block 8 will be transmitted to the middle shaft 16 through the rotating rod one 15, and the rotating rod two 18 will cooperate with the rotating rod one 15 to transmit the overload pressure at the bottom of the ring block 8 to the middle shaft 16 through the L-shaped connecting block 9, so that the middle shaft 16 drives the rotating rod one 15 and the rotating rod two 18 to fold and press the spring 14 of the connecting roller 12. The spring 14 will absorb the force, and through the elastic force of the spring 14, the rotating rod one 15 and the rotating rod two 18 will be reset and unfolded to resist and offset the overload, so as to prevent the cutting machine from being overloaded, and maintain the stability of the cutting process.
