The invention discloses a paper box conveying system for a multi-specification paper box filling machine. The paper box conveying system comprises a clamping groove conveying chain, transmission shafts, chain wheel driving mechanisms and first and second parallel mounting plates, wherein a pair of coaxial chain wheel transmission seats is fixedly arranged at the front and rear positions of each of the first and second mounting plates; the transmission shafts penetrate through the first mounting plate, the chain wheel transmission seats, the chain wheel driving mechanisms and the second mounting plate; the chain wheel driving mechanisms are arranged at the two ends of the transmission shafts between the first and second mounting plates respectively, and are connected with the chain wheel transmission seats in a relative rotating manner; the clamping groove conveying chain is meshed with the chain wheel driving mechanisms; a displacement regulation mechanism for regulating the distance between the two chain wheel driving mechanisms on the transmission shafts is further arranged on the first mounting plate. The paper box conveying system is simple in structure and low in manufacturing cost; the positions of the chain wheel driving mechanism on the mounting plates can be regulated according to the sizes of different products, so that the box opening and conveying requirements of paper boxes in various specifications can be met, and high universality is achieved.

The invention discloses a novel viscous damper with an adjustable damping coefficient. The viscous damper comprises a cylinder body, a piston and a piston rod; the two ends of the cylinder body are provided with guide sealing mechanisms, the two ends of the piston rod are matched with the guide sealing mechanisms at the two ends of the cylinder body respectively, and the piston is arranged in themiddle of the piston rod; the piston rod drives the piston to move in the cylinder body, and the piston divides the cylinder body into a first space and a second space; a damping channel making the first space connected with the second space is formed in the piston rod, and a plurality of openings are formed in damping channel and in the portions, on the two sides of the piston, of the surface ofthe piston rod respectively; the openings are closed or opened by sealing elements along with the displacement of the piston. The viscous damper has the advantages of being simple in structure, low inmanufacturing cost and capable of achieving damping multi-stage adjustment without being connected with a power source.

The invention belongs to the field of printing, and in particular relates to an environment-friendly dust collection mechanism for printing equipment, which includes a box body in which a first ventilation chamber and two second ventilation chambers are arranged, and the first ventilation chamber Pistons are slidably connected to the second ventilation chamber and a gear rod is fixedly connected to the piston, and one end of the gear rod is set through the box body, and the first ventilation chamber and the second ventilation chamber are equipped with driving mechanism, and a linkage mechanism is arranged between each driving mechanism, and the first ventilation chamber and the second ventilation chamber are communicated with ventilation pipes. The present invention can drive the piston to reciprocate through the cooperation of the provided driving mechanism and the gear rod, and by reversely driving the driving mechanism of the first ventilation chamber, the first ventilation chamber and the second ventilation chamber can be reciprocated at intervals The paper is sucked and blown, so that the dust on the paper can be collected in time and put on the vacuum cover, so as to avoid the dust from flying around and affecting the environment.

The invention discloses an oil pump of an automobile engine. The oil pump comprises a pump body, a pump shaft, an outer rotor, an inner rotor and a pump cover, wherein an oil inlet cavity and an oil outlet cavity are formed in the two ends of the pump cover respectively, the oil inlet cavity communicates with the pump body, a circular arc-shaped third pipeline is in through connection with the upper portion of the oil outlet cavity, one side of the third pipeline is fixedly connected with a second pipeline, the third pipeline communicates with the second pipeline through a second through hole,the other side of the second pipeline is connected with an accommodating cylinder through a first pipeline, the accommodating cylinder communicates with the first pipeline through a first through hole, a second piston is connected with the interior of the accommodating cylinder, a third spring is connected to the lower portion of the second piston, the interior of the second pipeline is fixedly connected with a first insertion rod through a first support, a first piston movably sleeves on the first insertion rod, and a second spring is connected to the lower portion of the first piston and the first support. The oil pump has the advantages that defects in the prior art can be overcome, wear of parts of the engine can be better prevented from being increased.

The invention provides an automatic travel regulating device for a pressing machine. A pair of main motors is connected with two sides of a frame symmetrically; an eccentric shaft sleeve mechanism is mounted in the frame; the shaft ends on two sides of the eccentric shaft sleeve mechanism are connected to and inserted into the main motors through splines; a link mechanism is mounted at the middle eccentric part of the eccentric shaft sleeve mechanism through a bearing sleeve; a sliding block mechanism is positioned under the link mechanism and is connected with the link mechanism through dowel pins; a guide mechanism is mounted on the frame in a position under the link mechanism; the sliding block mechanism slides up and down in the guide mechanism; an eccentric sleeve regulating mechanism and a rotary key regulating mechanism are mounted on the frame; the working parts of the eccentric sleeve regulating mechanism and the rotary key regulating mechanism are arranged in the grooves of the frame, which are positioned under support necks on two sides of the eccentric shaft sleeve mechanism. The automatic travel regulating device can be widely applied to modern pressing machines and has the outstanding advantages of simple structure, low cost, small occupied area, quickness in regulation, large transmission moment, high degree of automation and the like.

The invention discloses a splash-proof adjustable plug, which is fixedly connected with a screw rod and a head. The screw rod is provided with a blind hole along the axial direction, and the screw rod is provided with several oil discharge holes along the circumferential direction. The entrance of the oil discharge hole is connected with the blind hole. The holes are connected, the oil discharge hole is arranged obliquely, and the distance between the outlet of the oil discharge hole on the outer peripheral surface of the screw and the head is greater than the distance between the inlet of the oil discharge hole and the head, and the flow rate can be controlled by adjusting the screw-out length of the plug; It also prevents liquid from splashing on the operator during the draining process.
