[0016] Beneficial effects:

[0017] 1. This type of conveying and flattening equipment for underwear production, the underwear moves on the conveyor belt, and when it moves to the inside of the second mounting cover, the second hydraulic rod drives the cleaning frame to move downward, and the cleaning frame drives the cleaning roller at the lower end of the cleaning pressing plate to contact the underwear. As the second hydraulic rod drives the cleaning frame to move downward, the cleaning pressing plate rotates to both sides, and the cleaning pressing roller moves along the surface of the underwear, which is convenient for cleaning the impurities on the surface of the underwear and can flatten the underwear at the same time. When the cleaning pressing plate rotates, the sliding seat is driven by the movable support rod to move along the fixed guide rod to compress the reset spring, so that under the action of the reset spring, the second hydraulic rod can drive the cleaning frame to move upward, and the cleaning pressing plate can be restored to its original position. As the underwear continues to move on the surface of the conveyor belt, under the action of the pressing roller frame, the underwear can be flattened in the other direction, so that the underwear has a good conveying and flattening effect.

[0018] 2. For this type of conveying and flattening equipment for underwear production, the user rotates the pull block to pull the installation block to move, and the installation block drives the installation rod to move, and the installation rod drives the movable block to move inside the movable groove to compress the tensioning spring. When the installation block moves out of the installation hole, the installation rod can be pulled out from the inside of the slot, so that the cleaning roller is pulled out from between the two installation blocks, which is convenient for quick replacement and maintenance of the cleaning roller.

[0019] 3. This type of conveying and flattening equipment for underwear production has a movable support to support the conveying frame, and the universal wheel at the lower end of the movable support can facilitate the movement of the conveying frame. The user rotates the adjusting screw sleeves on both sides, and the lifting screw moves upward or downward under the action of the thread as the adjusting screw sleeve rotates. The two adjusting screw sleeves on the same side of the displacement rotate synchronously under the action of the transmission sprocket and the transmission chain, and the two lifting screws can move synchronously. The user lifts the four lifting screws on both sides to the same height, and can adjust the height of the conveying frame according to the needs of the user, which is convenient for the user to use. The user rotates the adjusting screw sleeve on one side of the mobile clamp seat to move the lifting screw on this side upward, and the lifting screw can drive the mobile clamp seat to move along the sliding rail to lift one end of the conveying frame, so that the conveying frame is inclined, which is convenient for the conveying frame to be adjusted and used according to the needs of the user.

[0020] 4. In this type of conveying and flattening equipment for underwear production, the user rotates the double-thread screw sleeve, and the width of the limit tooth block is equal to that of the groove, so that the clamping screw cannot rotate. The clamping screws on both sides move toward the outside of the double-thread screw sleeve as the double-thread screw sleeve rotates, and the clamping screw drives the limit tooth block to move. The limit tooth block is engaged with the fixing rack to prevent the moving support under the moving clamp seat from moving when the conveying frame moves, affecting the turnover of the conveying frame.
