The invention relates to the technical field of resin tile production, and discloses a die pressing device for resin tile production. The device comprises a hollow base, wherein the upper end of the hollow base is fixedly connected with a fixing frame through a plurality of supporting rods, the inner walls on the left and right opposite sides of the lower end of the fixing frame are rotatably connected with a lower die pressing roller through a rotating shaft, one end of the rotating shaft penetrates through and extends out of the fixing frame and is fixedly connected with a driven gear, the outer wall of the fixing frame is fixedly connected with a driving motor, and an output shaft of the driving motor is fixedly connected with a driving gear meshing with the driven gear. The die pressing device for resin tile production has the advantages that the distance between an upper die pressing roller and the lower die pressing roller can be quickly adjusted according to the required die pressing depth, and use is facilitated.

The invention discloses a convenient-to-move multifunctional ping-pong table for pupils. The ping-pong table comprises a ping-pong tabletop, first table legs, second table legs and a storage box, the first table legs are arranged at the lower end of the ping-pong tabletop, one second table leg is arranged on one side of each first table leg, the storage box is arranged on the lower side of the ping-pong tabletop, a plurality of self-locking rails are fixedly arranged on the upper surface of the storage box, self-locking pulleys are arranged on the lower surface of the ping-pong tabletop, and the storage box and the ping-pong tabletop are slidably connected through the self-locking pulleys and the self-locking rails. Stable placement of the ping-pong tabletop is realized by arranging the first table legs and the second table legs; a function of up-down moving of wheels is realized by arranging a pushing rod, electric rails and electric sliders; a function of storage and placement of rackets is realized by arranging a racket storage groove; a function of storage and placement of ping-pong balls is realized by arranging a ping-pong ball storage groove. The convenient-to-move multifunctional ping-pong table is simple in structure, reasonable in design, more humanized and suitable for popularization and use.

The invention relates to the technical field of filter stick dishing, and discloses a paper box clamping device on a filter stick dishing lifting mechanism, which comprises a U-shaped supporting seat, strip-shaped openings are formed in the side walls of two vertical parts of the U-shaped supporting seat, and the inner walls of the upper and lower opposite sides, corresponding to the strip-shaped openings, of the U-shaped supporting seat are rotationally connected with the same rotating screw rod through bearings; the bottom of the inner wall of the U-shaped supporting base is fixedly connected with a rotating mechanism used for driving the two rotating screws to rotate synchronously, the rod walls of the rotating screws are sleeved with lifting blocks in a threaded mode, the side walls of the two lifting blocks are both fixedly connected with side plates, and the same bottom plate is fixedly clamped between the lower ends of the two side plates. And the same top plate is fixedly clamped between the upper ends of the two side plates, and two first rectangular openings are symmetrically formed in the surface of the bottom plate. The paper box clamping and holding device on the filter stick tray loading lifting mechanism has the advantages that the placing stability of the whole paper box is guaranteed, the paper box clamping and holding device can be suitable for stable clamping and holding of paper boxes of different sizes, and the applicability is good.
