Sponge cutting device

Abstract

The invention relates to the technical field of sponge processing, and discloses a sponge cutting device. The sponge cutting device comprises a machine frame; a supporting cylinder is arranged on themachine frame; an upper box and a lower box are arranged on the supporting cylinder; each of the upper box and the lower box comprises a box column and two semi-box bodies; the two semi-box bodies ofthe upper box body and the two semi-box bodies of the lower box body are combined in a clamped mode so as to form an upper cavity and a lower cavity; lower protrusions are arranged on the upper box; upper protrusions are arranged on the lower box; a cavity for containing sponge can be formed after the upper protrusions and the lower protrusions are combined in a covered mode; a liquid nitrogen supply box and a water pump are arranged in the supporting cylinder; the upper box and the lower box communicate with the liquid nitrogen supply box and the water pump through hoses; a cutting mechanismis connected to the machine frame in a sliding mode and comprises a positioning rod arranged on the machine frame; a connecting rod is hinged to the positioning rod; a cutter is connected to the connecting rod; and a numerical control system is arranged in the positioning rod. The sponge cutting device has the advantages that the upper box and the lower box are arranged so that the sponge can be compacted, and therefore the relative hardness of the sponge can be improved, and the problem that notches are irregular due to extrusion deformation of the cutter in the cutting process of the spongecan be solved.

Description

technical field [0001] The invention relates to the technical field of sponge processing, in particular to a sponge cutting device. Background technique [0002] The main component of the sponge is polyurethane foam plastic, which has a network structure, low density and easy deformation, so it is difficult to use general mechanical devices for cutting processing. Therefore, the current processing of sponges with shape requirements uses mold foam molding, which is completed by professional manufacturers, resulting in an increase in the cost of sponge processing. [0003] In order to solve the problems referred to above, Chinese patent (CN104148671B) discloses a kind of cutting device of sponge, comprises lathe, fixing device and guiding device; Described lathe comprises lathe main shaft, lathe slide box; Described fixing device and lathe main shaft are fixed connection; the guide device is fixedly connected with the lathe crate. The above scheme is a sponge cutting device ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned deficiencies, the object of the present invention is to provide a sponge cutting device to solve the problem of uneven incision caused by the extrusion and deformation of the cutter head during the cutting process of the sponge, and to improve the cutting efficiency.
