Description

lump 19 of the pneumatic cylinder 20, the lower end of which is fixed on the frame 1.

In addition, the device has a quick-action clap 21. With it, the recess 4 and the plate 6 are connected to a vacuum system or to the atmosphere, or to a source of electricity (not shown) for the heating element 17 with a regulator to maintain the temperature of the upper plate 14 above 100 ° C.

The pivot arms 13 are connected through a cylindrical rod 22 with a bell-shaped cap 15, the upper sides 23 of which form a cylinder with a cross-sectional area equal to the area formed by the ring 7. The rod 22 passes through the center of another bell-shaped cap 24, the lower sides 25 of which are located adjacent to the sides 23 of the cover 15. For tightness, there are seals 26.

The pipe 27 connects cavity A through valve 21 to the vacuum reservoir 10. The cover 24 is fixed by compensating clamps 28 entering the slots 29 in the cover 24. The clamps keep the mechanical load constant so that the textile material is not affected by it.

During operation, the plate 14 is first heated, then using the pneumatic cylinder 20, the upper plate is lifted, and a textile material is laid on the porous plate 6, its size should not exceed the size of the plate. The carrier of the picture (decal) is placed on the textile material so that its painted surface contacts the textile material. When the pneumatic cylinder moves back, when the top plate 14 is heated, it presses against the bottom plate 3, the latches 28 enter the slots 29 and block the cover 24. At the same time, the pattern carrier is pressed tightly against the textile material, and

sealing ring 7 provides a hermetic seal.

. At the same time, valve 21 is activated, and air from the textile material and cavity A is removed through the vacuum tank 10, the pressure is reduced to 100 mm Hg. Art. and below, and the temperature of the upper plate 14 reaches 100 ° C. After the time required for

transferring the dye from the painted surface of the carrier to the textile material (which takes several seconds), the source of vacuum is turned off through valve 21, and the space between the plates is connected to

the atmosphere. The clips 28 are then removed from the sockets 29, and the upper plate is lifted by means of a pneumatic cylinder 20, the heating element is turned off and the colored textile material is removed, which can be further processed if necessary.

Subject invention

1. A device for printing on a textile material, comprising a top plate installed with the possibility of relative movement with a heating element and a bottom plate connected to

A vacuum system characterized in that, in order to improve printing quality, the bottom plate has a recess and is provided with a porous plate of sinter stainless steel located in the recess flush with the top plane of the plate and a sealing ring installed in a groove formed around the porous plate. 2. The device according to claim 1, characterized by

the fact that on the top plate are located the clamps to maintain a constant load on the material.
