The workpiece clamping device has the advantages that a middle adjusting gear can rotate, so that two adjusting gear screws can synchronously move, the adjusting clamping block on the left side of the kidney-shaped straight slot can assuredly parallelly move, high adjusting efficiency can be guaranteed, the workpiece clamping device is good in parallelism, the probability that the adjusting clamping blocks are jammed on the longitudinal adjusting base plate can be reduced, and the service life of equipment can be guaranteed.

The invention relates to the technical field of printing, in particular to a flexible printing plate pasting device. The flexible printing plate pasting device comprises a rack used for rotationally installing a printing roller. A movable platform is arranged on the rack. When the upper surface of the platform is flush with the upper portion of the printing roller, the platform is used for containing a flexible printing plate. An alignment ruler is in sliding connection to the rack and is parallel to the platform, and the sliding direction of the alignment ruler relative to the rack is perpendicular to the axis of the printing roller. A gap is formed in the position, corresponding to the upper portion of the printing roller, of the platform. The flexible printing plate pasting device has the effect that workers can conveniently and rapidly align and paste the flexible printing plate.

The invention discloses a workpiece clamping device of a track of a machine tool. The workpiece clamping device of the track of the machine tool comprises a base plate and a longitudinal adjusting base plate, wherein a longitudinal moving groove is formed in the bottom of the base plate; an adjusting screw hole is formed in a side wall of the base plate; at least two transverse adjusting tracks are fixed on the top of the base plate; adjusting grooves which are matched with the adjusting tracks are formed in the bottom of an upper clamping adjusting block; the adjusting tracks are inserted in the adjusting grooves; supporting plates are fixed at the front end and the rear end of the base plate; two ends of an adjusting lead screw are hinged to the two supporting plates; the middle of the adjusting lead screw is in screwed connection to screwed connection through holes formed in the left side and the right side of the upper clamping adjusting block; a bottom chute is formed in the bottom of the longitudinal adjusting base plate; and a dovetail-shaped sliding track which is arranged on the upper portion of the upper clamping adjusting block is inserted in the bottom chute. Two adjusting gear screws move synchronously by rotating a middle adjusting gear, an adjusting clamping block on the left side can move in parallel, and workpieces can be quickly adjusted in the transverse direction and the longitudinal direction.

The invention discloses a welding device and a welding method for a double-pipe transfusion bag. The welding device includes a welding mold, which is divided into two parts corresponding to the nozzle; the two parts are connected by a locking structure, so that the two parts of the mold run in the same direction during the welding process. The welding device of the double nozzle infusion bag of the present invention divides the welding mold into two parts, and connects the two parts through the locking structure, so as to ensure the parallel movement between each other; the elastic buffer pad is used to reduce the deviation of different nozzles due to material and size And it is difficult to match the impact, thus improving the quality of double nozzle welding. By setting the guide parts, the mold can maintain the correct relative position with the nozzle during the welding process, so as to avoid the deviation of the welding position of the nozzle.

The present invention relates to the technical field of the folder gluer, more specifically, relates to a new type of beam moving mechanism of the folder gluer. A new girder moving mechanism of a box gluer, including a lower beam and an upper beam. The rear end of the box gluer is equipped with a rear motor, which is connected to the rear end of the lower beam through a rear transmission mechanism. The front end is provided with a front-end motor, and the front-end motor is respectively connected with the front ends of the lower beam and the upper beam through the front-end transmission mechanism. The invention can effectively ensure the parallel movement of the girder. When the girder moves with a slight deviation or the distance between the front end and the rear end of the girder is required to be slightly different, the front end motor or the rear end motor can be individually adjusted to achieve this. It can ensure that the front end of the girder and the rear end of the girder move at the same distance when the girder moves, and it is not easy to cause the problem of the size of the cardboard.
