Description

TECHNICAL FIELD

[0001] The utility model relates to TPU elastic non -woven fabric processing technical field, concretely is a kind of cutting device for TPU elastic non -woven fabric processing. BACKGROUND

[0002] PU elastic non -woven fabric is a kind of non -woven fabric material with unique elasticity, which is mainly made of thermoplastic polyurethane (TPU).

[0003] According to the cutting device for non -woven fabric processing (announcement number: CN219260542U) of one kind of non -woven fabric processing, the fixed plate is connected with the first main guide rod and the first spring at one end of the carrier plate, the fixed plate bottom end is equipped with pressing plate, can be to the one side of non -woven fabric to be cut Place is pressed, by the second main guide rod, second spring and transmission rod cooperation connection with push flat roller at the other end of the carrier plate, can push non -woven fabric to one side, straighten the place to be cut, by the cutting knife being equipped with in the middle of carrier plate bottom, non -woven fabric is cut, by the setting of above-mentioned structure, can avoid the wrinkle of non -woven fabric cutting place, guarantee the effect of cutting.

[0004] However, in actual application, the cutting device still has some deficiencies. Especially after cutting is completed, when the carrier plate moves up to release the cut non -woven fabric, the release of the second spring will pull the transmission rod and the side shift plate back to the original position. Although this resetting action helps to prepare for the next cutting, in this process, the push flat roller will involuntarily move the cut fabric again close to the cutting knife. This phenomenon not only increases the difficulty of taking out the fabric, but also may cause unnecessary damage to the fabric, such as edge wear or stretching deformation, thereby affecting the cutting effect and the overall quality of the fabric. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of cutting device for TPU elastic non -woven fabric processing to solve the problems raised in the above background.

[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of cutting device for TPU elastic non -woven fabric processing, including top plate, the bottom of top plate is fixed with pneumatic cylinder, the output end bottom of pneumatic cylinder is fixed with bottom plate, the surface of bottom plate is provided with flattening assembly, limiting assembly, the flattening assembly includes: fixed frame, sliding rod two;

[0007] The limiting assembly includes:

[0008] Moving block, moving block is used to drive the synchronous movement of clamping block;

[0009] Clamping block, clamping block is used to limit sliding rod two;

[0010] Resist slot, resist slot is used to cooperate long plate to drive moving block to move.

[0011] Preferably, the movable block is slidably connected to the top of the base plate. A spring three is fixed to the surface of the movable block. A fixing plate is fixed to the end of the spring three away from the movable block. The fixing plate is fixed to the top of the base plate. A locking block is fixed to the side of the movable block away from the spring three. An abutment groove is provided on the top of the movable block. A locking groove is provided on the surface of the slide rod two. When the slide rod two moves upward, the inner wall of the locking groove abuts against the inclined surface of the locking block, which can drive the locking block and the movable block to move closer to the fixing plate. When the position of the locking block is parallel to the position of the locking groove, the movable block drives the locking block to move into the locking groove through the spring three. When the side of the locking block away from the inclined surface abuts against the inner wall of the locking groove, the slide rod two is limited. When the base plate moves upward to release the fabric, the fixing frame will not reset. When the base plate is at the top, the bottom of the long plate abuts against the inclined surface of the abutment groove, and the movable block and the locking block move away from the slide rod two. The locking block disengages from the locking groove, releasing the limitation on the slide rod two. Under the action of the spring two, the fixed frame and the flattening roller are reset through the movable plate.

A second sliding rod is fixed to the top of the fixed frame, with the top of the second sliding rod penetrating the slider and slidably connected to it. A second spring is fixed to the bottom of the slider, with the bottom of the second spring fixed to the top of the fixed frame. As the base plate moves downward, the pressure plate and the flattening roller contact the fabric. As the base plate continues to move downward, the movable plate flips, causing the fixed frame and the second sliding rod to move. The slider moves synchronously, and the fixed frame drives the flattening roller to move horizontally. The flattening roller smooths and straightens the fabric.

[0013] Preferably, a mounting base is fixed to the surface of the top plate, and a sliding rod is provided on the surface of the bottom plate. The sliding rod passes through the bottom plate and is slidably connected to the bottom plate. A pressure plate is fixed to the bottom of the sliding rod, and a spring is fixed to the top of the pressure plate.

[0017] 1. This cutter for processing TPU elastic nonwoven fabric, through the setting of a limiting component, when the slide bar two moves upward, the inner wall of the slot abuts against the inclined surface of the locking block. Through the spring three, the moving block can drive the locking block to reciprocate. At the same time, the side of the locking block away from the inclined surface abuts against the inner wall of the slot, thus limiting the slide bar two. When the bottom plate moves upward to release the fabric, the fixing frame will not reset. When the bottom plate is at the top, the bottom of the long plate abuts against the inclined surface of the contact groove, the moving block and the locking block move away from the slide bar two, the locking block disengages from the slot, and the limiting of the slide bar two is released. Under the action of the spring two, the fixed frame and the push roller are reset through the movable plate, which can facilitate the removal of the fabric and avoid unnecessary damage to the fabric.

[0018] 2. The cutter for processing TPU elastic nonwoven fabric, through the set smoothing component, when the base plate moves down, the pressure plate and the flattening roller contact the fabric. At the same time, as the base plate continues to move down, the first slide rod moves, the first spring is compressed, the movable plate flips and drives the fixed frame and the second slide rod to move. At the same time, the second spring is compressed, the slider moves synchronously, and the fixed frame drives the flattening roller to move horizontally, so that the flattening roller can smooth and straighten the fabric.
