The utility model discloses spinning production equipment for cationic dyeable polyester pre-oriented yarn, and relates to the technical field of spinning production. Comprising a spinning machine body, the spinning machine body is provided with a winding mechanism used for spinning production of cation dyeable polyester pre-oriented yarn, tows passing through an adjusting assembly enter a winding assembly, a movable block slides on a sliding rod, a protruding block is arranged in the movable block and slides along an annular groove in a reciprocating lead screw, and the movable block can slide along the annular groove in the reciprocating lead screw. The movable block slides along the sliding rod through the reciprocating lead screw, then the movable rod and the wobble wheel are driven to do reciprocating motion, a rubber ring on the edge of the wobble wheel makes contact with a tow, in the reciprocating motion process of the wobble wheel, the tow is evenly wound around the winding shaft, and the limiting rod can limit the position of the tow to a certain degree; the tows are prevented from falling off from the wobble wheel, the problem that the tows are stacked, overlapped or irregularly wound on the winding shaft is solved, and the winding quality and appearance are improved.

The utility model relates to the technical field of packaging box machining equipment, and discloses a feeding structure of packaging box cutting equipment, which comprises a rack, a conveying assembly is mounted on the outer wall of the rack, the conveying assembly comprises a main shaft and an auxiliary shaft, and the main shaft and the auxiliary shaft are rotatably connected to the opposite outer walls of the two sides of the rack respectively; the outer wall of the driving conveying roller and the outer wall of the driven conveying roller are provided with a conveying belt in a matched mode, the outer wall of the machine frame is provided with a deviation rectifying and limiting mechanism, and the deviation rectifying and limiting mechanism comprises two side plates capable of moving relatively. When it is detected that the paperboard deviates, the side plate can push the paperboard back to a correct conveying path in time, the deviation phenomenon is effectively corrected, it is guaranteed that the paperboard is conveyed at the accurate position all the time, the cutting precision is greatly improved, defective products and waste products are remarkably reduced, and the product quality and the production efficiency are improved.

The utility model discloses an evaporator fin pressing device, which belongs to the technical field of evaporator production and comprises a support frame used for supporting evaporator fins, a fixing plate is mounted at the top of the support frame, four fixing rods used for supporting and guiding are welded at the top of the fixing plate, a mounting plate is mounted at the tops of the fixing rods, and the mounting plate is mounted on the support frame. A power box and a telescopic rod are mounted at the top of the mounting plate, a movable part of the telescopic rod is connected with a connecting disc, a pressing plate is welded to the bottom of the connecting disc, a cross-shaped groove for guiding is formed in the pressing plate, a cross-shaped moving plate is slidably mounted in the cross-shaped groove, a connecting column is connected to one side of the cross-shaped moving plate, and the connecting column is connected to the other side of the cross-shaped moving plate. According to the evaporator fin pressing device, the pre-pressing capacity can be improved, distortion or deviation generated in the production and transportation process of fins can be effectively corrected, the pressing uniformity and stability are improved, the production efficiency is improved, and the cost is reduced.
