This invention relates to the field of paper conveying equipment technology, specifically to a paper conveying unit with convenient pressure adjustment. It includes an upper belt mounted on the upper part of the frame and a lower belt mounted on the lower part of the frame. The upper belt houses several fixed rollers, and the lower belt houses several pressure adjusting rollers. The unit also includes a lower belt power transmission chain; a roller adjusting assembly; a lower roller pneumatic tightening device; a lower roller manual tightening device; and a lower belt tightening device. In this convenient pressure-adjustable paper conveying unit, the lower belt power transmission chain drives the upper and lower belt rollers, eliminating the need for complex chain winding. Furthermore, when the upper belt moves back and forth, the upper and lower belt rollers move simultaneously without affecting the chain length, achieving simultaneous power to both the upper and lower belts. The upper belt can move freely back and forth, and the roller adjusting assembly connects all the pressure adjusting rollers to tension springs.

The invention discloses a stacking device of a rotary cutter, and relates to the field of transportation or storage, the stacking device comprises an outer frame and a cart, and a sheet conveying and cleaning mechanism, a blanking mechanism and a sheet limiting mechanism are sequentially arranged in the outer frame. Second gears at the ends of the two sets of lower cleaning rollers rotate synchronously and are meshed with third gears above the second gears respectively, the third gears drive the corresponding upper cleaning rollers to rotate, and therefore the lower cleaning rollers and the upper cleaning rollers rotate to clean residual chippings on the outer surfaces of rotary-cut sheets, the situation that the chippings influence the stability of sheet stacking is avoided, and the stacking quality of the rotary-cut sheets is improved. The first belt transmission assembly and the second belt transmission assembly are in meshing transmission through a second gear and a third gear, it is guaranteed that the rotating direction of the lower cleaning roller and the rotating direction of the upper cleaning roller are opposite, the lower cleaning roller and the upper cleaning roller clean chippings on the upper side and the lower side of the rotary cutting sheet at the same time, and meanwhile conveying of the rotary cutting sheet is facilitated. Therefore, the rotating speed of the lower cleaning roller in the same direction is higher than that of the conveying roller, and conveying of rotary-cut sheets is accelerated.

This utility model discloses a vibration-damping worktable for rotary machining, belonging to the technical field of rotary machining equipment. It includes a rotary motor, a supporting arm, multiple machining surfaces, and a composite vibration-damping structure. The supporting arm includes multiple cantilever arms arranged circumferentially. Each machining surface is connected to its corresponding cantilever arm via at least one composite vibration-damping structure. The composite vibration-damping structure includes a sleeve and a locking screw. The sleeve passes through and connects to the cantilever arm, while the locking screw passes through the sleeve and is threadedly connected to the machining surface. The sleeve has a hollow stepped cylindrical structure inside, including a vibration-damping groove, a through-hole, and a spring groove. The composite vibration-damping structure also includes an elastic vibration-damping head and a spring sleeved on the locking screw, respectively located within the vibration-damping groove and the spring groove. This utility model enables the machining surface to quickly reach a stable state during rapid start-up and stop of rotary machining, improving machining efficiency and accuracy.

The utility model discloses a positioning device of a plastic suction mold. The positioning device comprises a workbench, leveling mechanisms are installed on the periphery of the bottom end of the workbench, a containing table is arranged at the upper end of the workbench, a lead screw nut is installed in the middle of the containing table, a lead screw is rotatably installed in the lead screw nut, the two ends of the lead screw are rotatably installed in the middle of the interior of the workbench, and one end of the lead screw penetrates through the workbench to be installed at the front end of a transmission. The transmission is installed on one side of the workbench, a motor is installed at the rear end of the transmission, and a bubble level is installed at the upper end of the containing table. The working table is leveled through the leveling mechanism, leveling of the working table is detected through the bubble level in the leveling process, it is avoided that the working table inclines, and use of the working table is affected, a mold is placed at the upper end of the containing table, the clamping mechanism is started through the switch, and the containing table is clamped and fixed through the clamping mechanism.
