Description

Technical Field

[0001] The utility model relates to the field of stentering machine accessories, in particular to an automatic edge trimming device with a dust suction function for a stentering stentering machine. Background Art

[0002] Patent No. "CN205741714U" discloses "a trimming device for a stentering and setting machine", which is used to cut the edges of fabrics and suck out the cut edges of fabrics through a fabric suction tube. Since some special fabrics will produce certain fabric scraps or powder, or pulp edge debris after the edges of fabrics are cut, these debris may not be completely sucked out with the fabric edges at the suction tube. Those that are not sucked out will accumulate on the parts around the suction tube or remain on the fabric, affecting the quality of the fabric. Utility Model Content

[0003] The utility model aims to provide an automatic edge trimming device with a dust suction function for a stenter setting machine.

[0004] The innovation of the utility model is that by adding a dust suction pipe and a dust suction cover, residual dust and debris can be washed out while cutting off the cloth edge.

[0005] In order to achieve the above utility model purpose, the technical solution of the utility model is:

[0006] An automatic edge trimming device with a dust suction function for a stentering setting machine comprises a frame, a cloth supporting frame installed on the frame, a lower cutting knife is provided below the cloth supporting frame, an upper cutting knife corresponding to the lower cutting knife is provided above the cloth supporting frame, blowing pipes are provided above and below the cloth supporting frame, one side of the upper cutting knife is a feeding end, and the other side is a discharging end, the blowing pipe is located at the feeding end and the air outlet of the blowing pipe is between the upper cutting knife and the lower cutting knife, an edge suction pipe is provided on one side of the discharging end, a dust hood is provided above the cloth supporting frame at the discharging end, and the dust hood is connected to the dust suction pipe.

[0007] Furthermore, a mesh plate is provided at the bottom of the dust hood to prevent the cloth from being sucked into the dust hood.

[0008] Furthermore, a cloth pressing rod is provided on one side of the cloth inlet end and / or one side of the cloth outlet end of the cloth supporting frame to press the cloth to prevent the cloth from being sucked up.

[0009] Furthermore, the frame is provided with a first adjustment component for adjusting the height of the cloth pressing rod, so as to facilitate adjusting the upper and lower positions of the cloth pressing rod according to the thickness of the cloth.

[0010] Furthermore, the No. 1 adjustment component includes a waist-shaped hole arranged vertically on the frame, the cloth pressing rod is inserted into the waist-shaped hole, and then is screwed and limited by screws and nuts.

[0011] Furthermore, a three-way valve is provided on the dust suction pipe. When the trimmed cloth strips are free of dust, the three-way valve is closed, and the dust suction pipe can be flexibly selected to be enabled or disabled.

[0012] Furthermore, the upper cutter is driven by the main shaft, and a felt fixing plate is fixed on the frame, and a protective cover is provided on the felt fixing plate to be supported under the main shaft. During the cutting process, the fabric is cut, and the scattered yarns in the warp direction of the fabric will swing irregularly under the influence of the airflow. Since there is a high-speed rotating driving shaft above the fabric, the yarns will easily be entangled on the shaft, resulting in the fabric that is finally cut off not being smoothly sucked away by the wind, affecting product quality and downtime for maintenance. It is also quite difficult to clean the part after downtime, and improper operation will damage the blade. The main shaft is separated by a protective cover to prevent the yarn from being entangled on the main shaft.

[0013] Furthermore, the frame is provided with a second adjustment component for adjusting the angle and height of the dust hood, so that the height of the dust hood can be adjusted according to the cloth, and the angle of the dust hood can also be adjusted.

[0014] Furthermore, the second adjustment component includes a connecting plate connected to the frame, the connecting hole on the connecting plate connected to the frame is a vertically arranged waist hole, the connecting plate is provided with a first connecting rod, the first connecting rod is provided with a connecting block, the connecting block is connected to the second connecting rod, the dust suction pipe is connected to the second connecting rod, the connecting block is provided with a first through hole inserted into the first connecting rod, the connecting block is also provided with a second through hole inserted into the second connecting rod, the side wall of the first through hole is provided with a notch, the connecting block is provided with a locking screw for locking the notch, and the side wall of the second through hole is provided with a tightening screw.

[0015] The beneficial effects of the utility model are:

[0016] 1. In the utility model, by adding a dust suction pipe and a dust suction hood, residual dust and debris can be washed out while cutting the edge of the cloth.

[0017] 2. The automatic trimming device of the utility model can prevent scattered yarns from being entangled on the main shaft during the trimming process, without affecting production.

[0018] 3. The dust suction pipe in the utility model can be flexibly selected to be activated or deactivated. BRIEF DESCRIPTION OF THE DRAWINGS
