Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth processing technology, specifically a glass fiber cloth cutting mechanism. Background Technology

[0002] Fiberglass cloth is a plain weave fabric made of untwisted roving. It is mainly used in the production of various electrical insulation laminates, printed circuit boards, vehicle bodies, storage tanks, boats, molds, etc. The characteristics of the fabric are determined by fiber properties, warp and weft density, yarn structure, and weave.

[0003] During the fabric cutting process, the fabric is usually placed directly on the cutting table. When using the cutting scissors to cut the fabric, the fabric will be subjected to a certain pushing force and will move. Without a good clamping and positioning structure, cutting deviations are likely to occur during cutting. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figs. 1-3This utility model discloses a cutting mechanism for fiberglass cloth, including a cutting table 1. A Y-axis linear module 2 is installed on the cutting table 1, and a gantry frame 3 is installed on the slide of the Y-axis linear module 2. An X-axis linear module 4 is installed on the gantry frame 3, and a Z-axis linear module 5 is installed on the slide of the X-axis linear module 4. An ultrasonic cutting blade 6 is installed on the slide of the Z-axis linear module 5, and a pre-compression assembly 7 is installed on the ultrasonic cutting blade 6. When cutting the fiberglass cloth, the Z-axis linear module 5 drives the ultrasonic cutting blade 6 to descend until it contacts the cloth. At the same time, the U-shaped rod 76 in the pre-compression assembly 7 is pressed against the periphery of the cutting point of the cloth under the elastic tension of the shock-absorbing spring 75 to achieve the compression of the cloth. During the movement of the ultrasonic cutting blade 6, the U-shaped rod 76 can slide and follow on the cloth, without affecting the cutting of the cutting blade.

[0019] The pre-compression assembly 7 includes a sleeve 71, a connecting rod 72, a sliding sleeve 73, a hand-tightening bolt 74, a shock-absorbing spring 75, and a U-shaped rod 76. The connecting rod 72 is embedded on both sides of the sleeve 71. The sliding sleeve 73 slides on the connecting rod 72 and is fastened to the connecting rod 72 by the hand-tightening bolt 74. One end of the shock-absorbing spring 75 is connected to the sliding sleeve 73, and the other end of the shock-absorbing spring 75 is connected to the U-shaped rod 76.

[0020] Specifically, the cutting table 1 has grooves 8 on both sides, and the Y-axis linear module 2 is installed in the grooves 8.

[0021] In this embodiment, the groove 8 is used for positioning and installation of the Y-axis linear module 2. The Y-axis linear module 2, the X-axis linear module 4, and the Z-axis linear module all achieve linear motion of the load by driving transmission elements such as belts or ball screws.

[0022] Specifically, the pre-compression component 7 is located at the lower part of the ultrasonic cutting blade 6 and covers the blade part of the ultrasonic cutting blade 6.

[0023] In this implementation scheme, while the linear module 5 drives the ultrasonic cutting blade 6 to descend, the pre-clamping component 7 presses against the periphery of the fabric cutting point. The principle of the ultrasonic cutting blade 6 is to use the energy of ultrasonic waves to locally heat and melt the material to be cut, thereby achieving the purpose of cutting the material.

[0024] Specifically, the sliding sleeve 73 is provided with a threaded hole 77, and the hand-tightening bolt 74 is threaded into the threaded hole 77, with its head end abutting against the connecting rod 72.

[0025] In this embodiment, the threaded hole 77 is a connecting structure used for the installation of the hand-tightening bolt 74. Through the action of the hand-tightening bolt 74, the fastening between the sliding sleeve 73 and the connecting rod 72 can be achieved.

[0026] Specifically, the bottom of the sliding sleeve 73 is provided with an upper mounting block 78, and one end of the shock-absorbing spring 75 is fixed to the upper mounting block 78 by screws.

[0027] In this embodiment, the upper mounting block 78 is an assembly structure used to connect one end of the shock-absorbing spring 75 to the sliding sleeve 73 with screws.

[0028] Specifically, the top of the U-shaped rod 76 is provided with a lower mounting block 79, and the other end of the shock-absorbing spring 75 is fixed to the lower mounting block 79 by screws.

[0029] In this embodiment, the lower mounting block 79 is an assembly structure used to connect the other end of the shock-absorbing spring 75 to the U-shaped rod 76 with screws.

[0030] During use, when cutting fiberglass cloth, the Z-axis linear module 5 drives the ultrasonic cutting blade 6 to descend until it contacts the cloth. At the same time, the U-shaped rod 76 in the pre-compression assembly 7 is pressed against the periphery of the cloth cutting point under the elastic tension of the shock-absorbing spring 75 to compress the cloth. During the movement of the ultrasonic cutting blade 6 (the Y-axis linear module 2 and the X-axis linear module 4 are used to realize the movement of the cutting blade in the X and Y directions), the U-shaped rod 76 can slide and follow on the cloth, without affecting the cutting of the cutting blade.

[0031] In summary, when the fiberglass cloth cutting mechanism cuts the fiberglass cloth, the Z-axis linear module 5 drives the ultrasonic cutting blade 6 to descend until it contacts the cloth. At the same time, the U-shaped rod 76 in the pre-compression assembly 7 is pressed against the periphery of the cloth cutting point under the elastic tension of the shock-absorbing spring 75 to achieve the compression of the cloth. During the movement of the ultrasonic cutting blade 6, the U-shaped rod 76 can slide and follow on the cloth, without affecting the cutting of the cutting blade.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
