Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric processing, and in particular relates to a slitting device for non-woven fabric. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is made of polyester fiber and nylon fiber and is made through a needle-punching process. Non-woven fabric has many advantages such as moisture-proof, breathable, flexible, thin, flame-retardant, and low price. It can be used in many industries. During the processing of non-woven fabric, the production material is directly processed into a whole piece of cloth. Therefore, during the processing of non-woven fabric, a slitting device is often required to perform the slitting work.

[0003] Most of the existing slitting devices use circular knives and rotating shafts for cutting. When the circular knives are worn out after a period of use, the blades become blunt and some fibers cannot be completely cut off, causing damage to the cloth. When changing the knives of this slitting equipment, it is necessary to remove the bolts that fix the circular knives, remove the rotating shaft, take out the damaged circular knives, and install them after replacement. This problem seriously increases the downtime time for changing knives, greatly reducing the efficiency and frequency.

[0004] Therefore, in order to solve the above problems, it is necessary to design a slitting device for nonwoven fabrics. Utility Model Content

[0005] The utility model aims to provide a slitting device for nonwoven fabrics to solve the technical problem of inconvenient knife replacement in the existing slitting device.

[0006] In order to solve the above technical problems, the utility model provides a nonwoven fabric slitting device, comprising:

[0007] A support frame and a plurality of guide rollers connected to the support frame bearings;

[0008] The slitting assembly comprises: a gantry frame arranged on a supporting frame, at least two knife seats slidably connected to the bottom of the gantry frame, and a slitting knife plugged into the bottom of the knife seats; wherein

[0009] The slitting knife is suitable for slitting the nonwoven fabric conveyed by the guide roller; and

[0010] The slitting knife is suitable for being removed from the knife seat when worn, so that a new slitting knife can be replaced and plugged into the knife seat.

[0011] Furthermore, the slitting assembly further comprises: a guide rail arranged at the bottom of the gantry, and a slide block arranged at the top of the knife seat; wherein

[0012] The slide block is suitable for sliding on the guide rail to adjust the cutting position of the knife seat and the cutting knife.

[0013] Furthermore, the guide rail is dovetail-shaped; wherein

[0014] The guide rail is adapted to the slider; and

[0015] The dovetail-shaped guide rail is suitable for limiting the upward and downward movement directions of the slider.

[0016] Furthermore, the slitting assembly further comprises: a guide shaft connected to the inner walls on both sides of the gantry;

[0017] The guide shaft passes through the tool holder; and

[0018] The knife seat is suitable for sliding on the guide shaft.

[0019] Furthermore, the slitting assembly further comprises: a bolt engaged with the knife holder;

[0020] The bolt is adapted to abut against the guide shaft when tightened; and

[0021] The guide shaft is suitable for increasing the friction force with the knife seat when it abuts against the bolt.

[0022] The beneficial effects of the utility model are:

[0023] (a) The utility model pushes the knife holder, which slides at the bottom of the gantry, and the knife holder drives the slitting knife to move to a suitable position. The slitting knife slits the non-woven fabric conveyed by the guide roller. When the slitting knife is worn, the machine is turned off, the slitting knife is removed from the knife holder, and a new slitting knife is replaced and plugged into the knife holder. By changing the shape of the slitting knife and the connection relationship between the knife holder and the slitting knife, the above steps are performed to facilitate the knife change and save the knife change time.

[0024] (ii) The utility model pushes the knife holder, which drives the slider to slide on the guide rail and the knife holder slides on the guide shaft. After the knife holder drives the slitting knife to a suitable position, the bolt is tightened. The bolt abuts against the guide shaft, and the friction between the guide shaft and the knife holder increases. The knife holder can no longer slide on the guide shaft. Through the above steps, the effect of convenient and quick adjustment of the slitting distance is achieved.

[0025] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the utility model. The purpose and other advantages of the utility model are realized and obtained by the structures particularly pointed out in the description and the drawings.
