The invention provides a stacking device for a plate production line, which relates to the technical field of plate stacking, to solve the problem that the existing plate stacking device cannot effectively fix and limit the plate according to the size of the plate, resulting in a certain degree of damage to the plate when stacking The problem includes the main body of the device; the main body of the device is fixedly installed with a load-bearing mechanism, and the top of the main body of the device is rotatably installed with an auxiliary device; the outer side of the load-bearing mechanism is fixed with a fixing device, and the outer side of the load-bearing mechanism is fixed with a buffer mechanism; The outer side of the auxiliary device is fixed with a protective mechanism, and the top of the auxiliary device is rotated with a connecting mechanism; by setting the tooth plate A, the tooth plate B and the fixed gear, the effect of making the side plate A and the side plate B move in the opposite direction at the same time is realized. ;Using threaded rods to be threadedly connected with the fixing frame realizes the effect of driving side plate A and side plate B to move, and plays the role of adjusting the position of side plate A and side plate B according to the size of the plate.

The invention relates to a storage container for lunar soil samples realized by three-axis compression and locking with a variable inner diameter, comprising an upper sealing cover, an outer barrel, an elastic inner barrel, an inner diameter shrinking wedge, an annular linkage mechanism, an axially tightening elastic member, and an elastic inner barrel Sleeved in the outer barrel, the ring linkage mechanism is set between the elastic inner barrel and the outer barrel; the bottom wall of the outer barrel is provided with a slope, the lower end of the ring linkage mechanism is in contact with the slope and can move relative to the slope, and the upper end of the ring linkage mechanism is in contact with the inner diameter contraction wedge The wedge-shaped slope of the block is in contact with and can move relative to the shrinking wedge of the inner diameter; one end of the axially tightening elastic member is connected with the bottom wall of the outer barrel, and the other end is fixed with a slider that can seal and slide in the elastic inner barrel; the upper sealing cover is fastened On the top of the outer barrel, and by squeezing the inner diameter contraction wedge, the upper and lower ends of the ring linkage mechanism slide along the wedge-shaped slope and the slope respectively, so as to realize the radial contraction of the elastic inner barrel, and at the same time compress the axially tightening elastic member. The invention can preserve the original bedding information of lunar soil samples as much as possible.

The invention discloses a mechanical sealing device with extending and rotating functions. The mechanical sealing device comprises a shaft sleeve, a shaft sleeve transmission sleeve, a moving ring transmission sleeve, at least one moving ring, a static ring and a sealing box body, wherein the static ring are the same with the moving ring in number, the shaft sleeve is a hollow shaft sleeve, the shaft sleeve is fixedly arranged on a main shaft, the shaft sleeve is installed in the shaft sleeve transmission sleeve, the moving ring transmission sleeve is arranged on the shaft sleeve transmission sleeve in a sleeve mode, the moving ring transmission sleeve is fixed on the moving ring in a sleeve mode, the moving ring is movably installed on the static ring, the static ring is fixed on the sealing box body, and the sealing box body is arranged on the outer side of the static ring. According to the mechanical sealing device, it is guaranteed that the shaft sleeve can effectively slide in the shaft sleeve transmission sleeve, the sealing performance can be ensured, the poor sealing caused by the fact that the shaft sleeve moves is avoided, in the using process, once the shaft sleeve is damaged, the shaft sleeve can be directly replaced without detaching the whole seal, so that the maintenance time and cost are effectively reduced, and the production efficiency is improved.
