The turntable type packaging machine is provided with the bag supporting mechanism, can keep the bag mouth stable after being opened by suction, and ensures stable feeding work in the subsequent sequence.

The utility model relates to the field of textile auxiliary instrument, concretely relates to a cleaning mechanism of double twister, including casing, guide wheel and guide wire bar still include: fixed in the wire guide plate of casing, its opening has wire hole, wire hole, guide wheel and guide wire bar are sequentially arranged along the yarn conveying direction, fixed in the lower cleaning box of wire guide plate, and located between guide wheel and guide wire bar, set up in the upper cleaning box of lower cleaning box top, the utility model discloses through setting up the rotation pipe of single -hand operation and the linkage mechanism of lifting rod linkage, only need to rotate lower locking piece when changing the line can drive the vertical rise of upper cleaning box, make the quick separation of upper and lower cleaning box, do not need to manually wear yarn, greatly simplify the operation process. Especially suitable for multi -spindle position production scene, significantly shorten the line changing time, improve overall production efficiency.

The application discloses a kind of anti-rebound mechanisms for blasting door opening, including base, shell, locking rotary arm, reset mechanism, unlocking mechanism and stopper;Shell is fixedly installed on base;Locking rotary arm is rotatably installed on shell by a rotating shaft;Reset mechanism is arranged between shell and locking rotary arm, for providing elastic reset force to locking rotary arm so that it has a tendency to rotate towards the locking position;Unlocking mechanism includes electromagnet and connecting head, electromagnet is fixedly installed on base, connecting head one end is fixedly connected on locking rotary arm, the other end is drivingly connected with the core of electromagnet;Stopper is fixedly connected on blasting door.Wherein, the locking rotary arm has a locking position in the reset mechanism drive and embedded with stopper to prevent the rebound of blasting door, and an unlocking position in the electromagnet drive and separated from stopper by overcoming the reset force of reset mechanism.The application can realize reliable locking and quick unlocking, simple and durable structure, easy to install and maintain.

This utility model discloses a casing clamping and sealing device, including a base plate and a mounting plate. The mounting plate is fixedly connected to the top of the base plate and has a through hole. A clamping assembly is provided on one side of the mounting plate, and a positioning assembly is provided on the mounting plate near the clamping assembly. The clamping assembly includes a fixed clamp, a positioning shaft, a movable clamp, and a tension spring. The fixed clamp is fixed to the surface of the mounting plate near the through hole and directly below it. The positioning shaft is fixed to the side of the fixed clamp near one end, and the movable clamp is movably sleeved on the surface of the positioning shaft. This utility model solves the problem in the prior art where the casing is opened at one end and sealed by hand with a thread, resulting in slow sealing speed and affecting the entire casing production.
