The utility model belongs to the field of space cloth pressing, and particularly relates to a space cloth processing and pressing device which comprises a working table, and a side plate is fixedly connected to the top of the working table. The side wall of the side plate is fixedly connected with a first motor; the output end of the first motor is fixedly connected with a containing groove. A second air cylinder is fixedly connected to the bottom of the placing groove; the output end of the second air cylinder is fixedly connected with a push plate. The top of the workbench is fixedly connected with a supporting column. A lantern ring is arranged outside the supporting column in a sleeving manner; the end part of the lantern ring is fixedly connected with a supporting plate; the top of the supporting plate is fixedly connected with a first air cylinder. The output end of the first air cylinder is fixedly connected with a pressing plate. The problem that the space cloth is adsorbed on the push plate and is inconvenient to take out after being compressed can be reduced by additionally arranging the second air cylinder, meanwhile, the space cloth can be downwards taken out after being pressed by additionally arranging the first motor so as to prepare for next processing work, and the working speed is effectively increased.

The utility model discloses a pencil double-color paint dipping and drying device which comprises a drying cylinder, a rotating column is rotationally connected to an inner cavity of the drying cylinder, a plurality of rotating discs are fixedly connected to the surface of the rotating column, a plurality of first perforated semicircular pipes are annularly distributed on the surface of the rotating column and fixedly connected with the rotating discs, and a plurality of second perforated semicircular pipes are annularly distributed on the surface of the rotating column and fixedly connected with the rotating discs. And one side of the first perforated semicircular pipe is slidably connected with a second perforated semicircular pipe, an inner cavity of the second perforated semicircular pipe is fixedly connected with a plurality of partition plates, and the right side of the drying cylinder is fixedly connected with a side plate. According to the double-color pen refill assembling and stacking device, the first perforated semicircular pipe, the second perforated semicircular pipe and the loading and unloading assembly are used in cooperation, double-color pen refills are rapidly assembled and stacked, then the double-color pen refills are rotationally dried under the cooperative driving effect of the servo motor, the stress fluted disc and the driving fluted disc and the cooperative use of the drying cylinder, the rotating column and the rotating disc, and the double-color pen refills are rapidly assembled and stacked. Therefore, the purposes of convenient loading and unloading of the double-color pen refill and uniform heating and drying can be achieved.

The invention discloses a soil heavy metal detector which comprises a machine body, and the machine body is communicated with a first connecting pipe and a second connecting pipe which have plastic performance; the objective table is movably matched with the machine body, and a gear is fixedly connected to the bottom of the objective table; the moving assembly is used for driving the objective table to move so that liquid can be dropwise added conveniently; the movable assembly is matched with the moving assembly and enables the vessel located on the objective table to shake back and forth in a reciprocating mode through a gear; by rotating the adjusting rod in a reciprocating mode, adjustment of up-and-down movement of the objective table and the vessel is completed, the objective table and the vessel are driven to rotate in a reciprocating mode at the same time, on one hand, an operator can dropwise add a mixed indicator according to personal habits conveniently by means of the lifting height, and on the other hand, the operator can conveniently drop the mixed indicator according to personal habits; on the other hand, full and rapid mixing of dropwise added materials is facilitated, and the mode is convenient to operate.
