Cloth cutting device of cloth spreading machine

Abstract

The invention discloses a cloth cutting device of a cloth spreading machine, and belongs to the technical field of clothing machines. The cloth cutting device comprises a cutting table, a left cloth pressing mechanism, a feed rack and a cutting head. A front wall plate is fixed to the left side of the upper portion of the front end of the cutting table, a rear wall plate is fixed to the left side of the upper portion of the rear end of the cutting table, and a cloth guide roller and a cloth supporting plate are arranged between the front wall plate and the rear wall plate. The left cloth pressing mechanism is arranged at the position, corresponding to the part above the cloth supporting plate, between the front wall plate and the rear wall plate. The front end of the feed rack is fixed to the front wall plate, and the rear end of the feed rack is fixed to the rear wall plate. The cutting head is connected with a cutting head driving mechanism which is arranged at the rear end or the front end of the feed rack. The cloth cutting device is characterized by further comprising a right cloth pressing mechanism which is connected to the position, corresponding to the right side of the feed rack, between the front wall plate and the rear wall plate. The structure is simplified, the cost is lowered, and energy is saved; the cloth cutting effect of the cutting head is ensured; the ends, facing the cutting table, of cloth cut by the cutting head can be pressed, so that it is ensured that the ends of the cut cloth are stacked on the cutting table in a flush mode.

Description

technical field [0001] The invention belongs to the technical field of garment machinery, and in particular relates to a cloth cutting device of a cloth stretching machine, which is used for cutting the cloth drawn by the cloth stretching device to a workbench. Background technique [0002] The aforementioned stretching machine usually includes a cloth feeding device (also called a "cloth releasing device"), a cloth pulling device and a cloth cutting device (also called a "cloth breaking device"). In the published Chinese patent literature, it can be seen that all the technical information about the cloth stretching machine, such as the "knitting fabric cloth machine" recommended by CN202988390U, and the "cloth stretching machine with a manipulator clamping mechanism" provided by CN103342251B, etc. Technical information about the cloth cutting device can also be found in the published Chinese patent documents; such as CN202626706U (an automatic cloth cutting machine), CN2026...

AI Technical Summary

Problems solved by technology

[0003] Typical such as the "cutting mechanism of cloth stretching machine" recommended by CN100458002C, this patent solution can objectively reflect the technical effect summarized in the 6th to 10th lines on page 4 of its specification, but there are the following shortcomings: First, because in addition to the necessary In addition to the cutting head driving motor of the structural system of the cutting head driving mechanism used to drive the cutting head to reciprocate in the width direction of the cutting table (the patent is called the working table of the stretching machine) and the cutting head's own cutting blade drive motor, Equipped with a torque motor, a pressure roller shaft drive motor (the patent is called the second motor) and a motor of the structural system of the gas generating device (the patent is called the first motor), which results in a complex structure, high manufacturing costs and is not conducive to saving power consumption; the second , as known in the industry, when the cutting disc (disc knife, the same below) of the cutting head is cutting the fabric, the cutting edge of the cutting disc is not allowed to contact the surface of the cutting table, otherwise the table top of the cutting table will be damaged. The cutting edge is cut, so the cloth needs to be pressed and the area corresponding to the cutting disc is suspended above the table top of the cutting table. To make the cloth suspended above the table of the cutting table and ensure the cutting effect of the cutting disc, only It is necessary to clamp the cloth on both sides corresponding to the cutting head at the same time, forcing the cloth to be in a relatively tight state. Only when the cloth is in a tight state can the cloth cutting effect of the cutting disc be brought into full play. However, this patent only It is difficult or even impossible to guarantee the cutting effect of the cutting blade by relying on the only one cloth pressing tube (patent called pressing bar) to press the cloth on one side or one side.
