Description

[0001] POLISHING MACHINE FOR LEATHER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leather polishing machine, and more particularly to a leather polishing machine for automatically polishing the surface of a leather fabric for manufacturing various leather products such as handbags, bags, shoes, belts and wallets.

Generally, in order to manufacture various leather products such as handbags, bags, shoes, belts, wallets, etc., the leather fabric is cut and manufactured.

At this time, the leather fabric is subjected to a fleshing process in which the raw material is limed and the bond tissue or the fat on the back of the leather is mechanically shaved and cleaned, The thick leather is subjected to a splitting process in which the leather is divided into two layers and after a shaving process in which the thickness of the leather is adjusted, dyeing and emulsifying oil to impart flexibility and stiffness to the surface of the leather and polishing the surface of the leather to polish the surface of the leather.

The leather fabric is finally subjected to a polishing process in which the surface of the leather is polished and polished.

Conventionally, in the early stage of the leather cloth polishing, the leather surface was polished by hand using a grinder, and the polishing operation was performed when the polishing process was completed. However, in case of using a grinder, even a skilled worker has a problem that the material of the leather is punctured or torn.

Conventional heat treatment polishing uses a flat plate press, which is performed by inserting a leather fabric between upper and lower molds with a coil and thermally compressing.

Conventional heat treatment and polishing of a leather fabric using such a flat press has solved the problem of punching or tearing of the leather fabric but the quality of the leather fabric before pretreatment is not uniform due to the uneven thickness. In addition, in the case of a wide leather fabric, there is a limitation in the width of the upper and lower molds. After performing the heat treatment and polishing operations for the widths of the upper and lower molds, the upper and lower molds are returned to their original positions. A worker carries out a new heat treatment polishing operation after manually moving the leather cloth, so that the productivity is remarkably lowered. In addition, since the flexibility of the leather fabric is lowered due to the influence of the press by the high pressure in the product, the gloss persistence is lowered compared with the mechanical gloss because the heat treatment glossing work is performed.

Also, since the heat treatment for applying the temperature is performed, a lot of energy is required, and the power consumption is increased, so that the cost of the polishing work of the leather fabric increases, resulting in an increase in production cost. In addition, since the worker moves the fabric material manually by hand, there is a high risk of a safety accident.

Korean Patent Laid-Open Publication No. 10-1995-0032645 (entitled " Method for mechanically polishing the leather surface and method for polishing the surface of the leather using the same) " ) Have been disclosed.

In order to obtain the surface gloss of the leather, the leather surface polishers are provided with a break-proof part and a friction luster member on the shaft of the drive motor, and the power is appropriately energized to the drive motor and the heat- And heat and heat generated by the heat generated from the heat treatment member is sprayed on the surface of the leather to control the heat treatment of the surface of the leather by applying a gloss member such as wax or a coloring pigment to the surface, And rubbing the surface of the leather with a striking friction-polishing member formed of fibers or the like to mechanically obtain a mechanically effective gloss on the surface of the leather.

The leather surface polishers are used to form a bristle part heat treatment member and a friction luster member on the shaft end of the driving motor. In case of a wide leather, the size of the brushing member is large but the productivity is deteriorated. There is a problem.

Further, the driving motor is provided with a breaker member, a heat treatment member, and a friction luster member, and appropriately energizes the power source to control the rotation of the driving motor and the heating of the heat treatment member.

[0034] As shown in Fig.

The polishing roller portion 30 rotates in a direction opposite to the roller rotation direction of the feeding roller portion 10.

A leather fabric that has undergone a pretreatment process such as liming, fleshing, tanning, splitting, shaving, dyeing, and fatliquoring (1) is polished by the polishing roller portion (30) at a high rotation speed.

The polishing member 30 is rotated at a high speed when it is polished by the polishing roller unit 30. It is preferable that a plurality of grooves 31a are formed on the outer circumference of the wear member 31 (refer to FIG. 5). When a plurality of grooves 31a are formed in the abrasive member 31, the abrasive debris can be smoothly discharged when the abrasive member 31 is in contact with the leather fabric 1. [ At this time, the abrasive debris generated when the abrasive member 31 contacts the leather fabric 1 is generated in a dust form because the leather fabric 1 has undergone a pretreatment process.

A large amount of heat is generated when the polishing roller portion 30 and the leather cloth 1 are in contact with each other. If the groove 31a is not provided, too much frictional heat is generated between the leather fabric 1 and the wear member 31 So that the leather fabric may be thermally deformed. The grooves 31a are also capable of discharging heat, thereby generating suitable frictional heat. Such a proper heat of friction brings about a gloss effect of the leather fabric 1, so that it is not necessary to perform a separate heat treatment step as in the conventional case. In addition, if a plurality of grooves 31a are not formed on the outer periphery of the wear member 31, the abrasive members 31 may accumulate abrasive debris, thereby hindering the abrasive member 31 from being polished. do.

At this time, the groove 31a is formed to be long at an acute angle from the axial center to the outer end of the wear member 31, and is preferably symmetrical (see FIG. 5). When the grooves 31a are formed at a certain angle, the removal of the polishing debris is facilitated and the accumulation of the polishing debris on the wear member 31 can be reduced, thereby reducing the deterioration of the polishing efficiency.

In addition, the wear member 31 is preferably made of a fiber material. At this time, a fiber material having high heat resistance and abrasion resistance such as glass fiber is used.
