Description

Shaming machine for leather processing {LEATHER SAMMING MACHINE}

The present invention relates to a shaping machine for leather processing, and more particularly, to effectively dehydrate liquid chemicals and additives added to raw hides, and to prevent damage to raw hides to maintain high quality during product molding. In addition, unlike the prior art by the addition of a tensile function to uniformly widen the area of the leather relates to a leather processing shaping machine that can be widely used in the initial process as well as the finishing process according to its purpose.

Leather processing is classified into the initial process of preparing the necessary leather before processing the leather, stabilizing the molecular structure of the leather, inorganic process, and finishing process of processing various dyeing or embossing for the purpose of leather.

Among these processes, the inorganic process is discussed.

Animal skin is an organic material that rots when left in the air. Therefore, in order to make these organic materials and inorganic materials, various chemical treatments are required, and these processes belong to the inorganic process.

On the other hand, in order to make raw hides into processing leather, they must be cleaned with chemicals. That is, the raw skin is soaked in water for a certain period of time by adding chemicals, and then put into a drum for washing.

Raw material which has undergone such a process is dewatered by being introduced into a dehydrator called a shaming machine.

By the way, since the shaping machine according to the prior art was simply a machine that squeezes water, that is, specialized in dehydration, there is a disadvantage that the utility of the machine is inferior.

Therefore, if a shaping machine is developed that is not only dehydrated but also has a tensile function that increases the area of the hides, it must be widely used for its purpose not only in the initial process but also in the finishing process. Is required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

1 is a structural diagram of a leather processing shaping machine according to a first embodiment of the present invention, Figure 2 is an enlarged view of the main portion of Figure 1 for explaining the principle of the shaping machine.

Prior to the description of the drawings, a brief description is given of the leather processing shaping machine of this embodiment.

The leather processing shaping machine of this embodiment simply peels from the machine (weaving liquid) with water (including liquid chemicals and additives) to reduce the damage of the leather, maintain high quality when forming the product, and further increase the leather. Plays a role to maximize the effect.

As will be described later, the leather processing shaping machine of the present embodiment is applied to five rollers (121, 122, 131 to 133) type by drastically deviating from the existing four types of rollers. It is possible to provide various methods and types in consideration of convenience.

On the other hand, as is widely known, various liquid chemicals and additives have to be used in the process of making the organic state of the animal's pre-processed animal skin (hereinafter referred to as raw hide) into an incorruptible mineral.

To process the hides, it is necessary to wash the liquid chemicals and additives cleanly and efficiently.

The leather processing shaping machine of this embodiment shown in Figs. 1 and 2 is capable of dehydrating the liquid added to the raw material, ie, liquid chemicals and additives neatly and efficiently, as well as preventing the damage of the raw material to ensure high quality in forming the product. It is possible to maintain and maintain the leather evenly.

In particular, the leather processing shaping machine of the present embodiment uses a method of dehydrating liquid chemicals and additives in the hide while pressing the hide at high pressure.

For reference, raw wool has wrinkles (animal necks, legs, tails, etc.) unlike wool or wallpaper types, which causes folding when passing through the press roller, which degrades the quality of leather as well as mechanical damage.

Therefore, there is a means of improving this point in the leather processing shaping machine of the present embodiment. This is explained further.

Referring to FIG. 1, the spreading roller 150 is disposed in one front region of the apparatus main body 100 forming an appearance. Unfolding roller 150 evenly spreads the raw material to improve the conventional problems and at the same time serves to widen the area of the raw material.

The spreading roller 150 evenly spreads the blades of stainless steel on a general round roller and spreads them out smoothly.

In addition, the spreading roller 150 is equipped with a plurality of blades (not shown) to remove various protein residues and foreign matters attached to the surface of the raw skin to increase the effect.

A motor M for driving the spreading roller 150 is provided around the spreading roller 150.

In the lower region of the spreading roller 150, a supporting roller 160 serving as a pedestal of the spreading roller 150 is provided. The support roller 160 may be a rubber coated roller.

On the other hand, unlike the prior art in which four rollers have been applied, in the present embodiment, two first and second upper rollers 121 and 122 and three first to third lower rollers 131 to 133, that is, a total of five Since the rollers (121, 122, 131 ~ 133), it is possible to simply deviate from the water weaving machine of the leather to reduce the damage of the leather and maintain a high quality when forming the product, and further maximize the effect of increasing the leather.

In this embodiment, the first and second upper rollers 121 and 122 may have a larger diameter than the first to third lower rollers 131 to 133, in which case the raw material passes between these rollers 121, 122, 131 to 133. This can increase the effect of rubbing, thereby increasing the effect of dehydration and the area of the hide.

In addition, the speeds of the first and second upper rollers 121 and 122 and the first to third lower rollers 131 to 133 are adjusted synchronously or individually, and the first and second upper rollers 121 and 122 and the first When the third lower rollers 131 to 133 are individually pressure-controlled, they may have a rubbing effect. In addition, it can provide cost- and time-saving benefits by eliminating unfolding and eliminating the need for protein powders that have been used to reduce friction after the process.

An upper front high pressure cylinder 141 and an upper rear high pressure cylinder 142 are connected to the first upper roller 121 and the second upper roller 122, respectively.

The upper front high pressure cylinder 141 causes the first upper roller 121 to pressurize downward, and the upper rear high pressure cylinder 142 causes the second upper roller 122 to pressurize downward.

The upper front and rear high pressure cylinders 141 and 142 in front of and behind the first and second upper rollers 121 and 122 may apply primary pressure and secondary pressure, respectively, where the primary pressure and the secondary pressure are different. Therefore, it protects the damage of the raw skin from the high pressure and makes the best value of the leather fabric by utilizing the raw material's value.

In other words, since the upper front and rear high pressure cylinders 141 and 142 in front of and behind the first and second upper rollers 121 and 122 can give different pressures, dehydration and raw skin may be given due to the pressure deviation depending on the direction of rotation and the direction of rotation. The effect of increasing the area of can be increased.

In the case of this embodiment, the pressing force of the upper front high pressure cylinder 141 is adjusted lower than the upper rear high pressure cylinder 142 plays an important role in preventing the damage of the raw material and the effect of the dewatering effect and the widening of the raw material area. Of course, these matters are only one embodiment, and the scope of the present invention should not be limited thereto.

The first and second upper rollers 121 and 122 are connected by an upper felt 171, and the first to third lower rollers 131 to 133 are connected by a lower felt 172. In this structure the hide passes between the upper and lower bolts 171, 172.

In this embodiment, the upper and lower bolts (171, 172) is made of a cotton material with a good tensile force can not only save the natural surface of the raw material, but also has good absorption power due to the characteristics of the cotton can increase the dehydration effect without direct damage to the raw material. .

Of course, if the absorption is good, other materials than cotton may be applied. For example, a material called synthetic may be used.

In addition, the friction is excellent and is increased by the effect that the raw material is rubbed while passing through the five rollers (121, 122, 131 ~ 133). If belts of different materials are used, damage to the raw material is severe and the desired dehydration effect cannot be expected.

First and second tension control units 181 and 182 are provided around the upper and lower bolts 171 and 172 to prevent the upper and lower bolts 171 and 172 from being pulled out. Both the first and second tension control units 181, 182 of this embodiment are applied in a tilted manner.

Each of the first and second tension adjusting units 181 and 182 of the inclination type may include first and second tension rollers 181a and 182a, and first and second tension rollers 181a and 182a respectively supporting the first and second tension rollers 181a and 182a. Second support bodies 181b and 182b and first and second cylinders 181c and 181c for driving the first and second supports 181b and 182b, respectively. A guide roller 182d is disposed at one side of the lower bolt 172.

Therefore, when the first and second cylinders 181c and 181c are moved up and down, the heights of the first and second tension rollers 181a and 182a are changed according to their inclination so that the higher ones become taut. To adjust the tension.

For example, when the rods of the first and second cylinders 181c and 181c are advanced, the upper and lower bolts 171 and 172 are tensioned to tension the upper and lower bolts 171 and 172, and vice versa. When the rod of 181c.181c is reversed, the tension of the upper and lower bolts 171 and 172 may be loosened, thereby reducing the service life and abrasion of the upper and lower bolts 171 and 172 so as to prevent excessive use even for long time use.

Hereinafter, with reference to FIG. 2, the operation of the shaming machine will be briefly described.

When the raw material proceeds in the direction of the arrow, the raw material passes through two first and second upper rollers 121 and 122 and three first to third lower rollers 131 to 133. In this case, the upper front and rear high pressure cylinders 141 and 142 of the first and second upper rollers 121 and 122 allow the first and second upper rollers 121 and 122 to pressurize downwards.

The rotation speed of the entire rollers 121, 122, 131 to 133 is the same as that of the first and second upper rollers 121 and 122 and the first to third lower rollers 131 to 133, but the rotation cycles of the rollers 121, 122, 131 to 133 are different. You may. Of course, the rotation speed between the rollers 121, 122, 131 to 133 may be applied differently.

On the other hand, when the raw material is located in the gap between the rollers 121, 131, and 132 between A and B, no pressure is applied. Therefore, when the raw material passes between A and B, the tension of the raw material is loosened and it is pressurized again through the B part.

In other words, the first and second upper rollers 121 and 122 and the first to third lower rollers 131 to 133 are pressed at a high pressure, and the first and second upper rollers 121 and 122 and the first to second presses. The space between the third lower rollers 131 to 133 becomes empty and does not receive pressure. In other words, during the passage of the raw material, the raw material is dehydrated as the raw material is repeatedly passed through the part under pressure and the empty part.

At this time, when looking at the direction of the force shown by the arrow in Figure 2 A and C portion is a portion that is directly pressured, B and D portion is a force that is strongly pulled in the direction of the pressure. As a result, the upper and lower surfaces of the raw material are rubbed and at the same time the pressure and the pulling force are repeated, thereby increasing the area of the raw material.

As such, according to the present embodiment, it is possible to efficiently dehydrate liquid chemicals and additives added to raw hides, and to prevent damage to raw hides, thereby maintaining high quality when forming products, and unlike the conventional art, The addition of a uniformly widening tensile function makes it possible to use a wide variety of purposes not only in the initial process but also in the finishing process, depending on its use.

The spreading roller 250 area has been technically changed. That is, the supporting roller 260 serving as the supporting role of the spreading roller 250 is arranged into the conveyor 265 unlike the first embodiment.

According to this structure, it is possible to further narrow the distance between the conveyor 265 and the upper and lower bolts (171, 170), through which the process of unfolding the raw material and the distance between the bolts (171, 170) can be reduced to the maximum. Can be minimized.

In addition, unlike the first embodiment, the support roller 260 only plays the role of supporting the spreading roller 250, and the roller portion is deleted. This can reduce the water clogging phenomenon.

In the first embodiment described above, the diameters of the first and second upper rollers 121 and 122 are larger than those of the first to third lower rollers 131 to 133, but in the present embodiment, the first and second upper rollers The diameters of the 221 and 222 and the first to third lower rollers 231 to 233 are identical. In this case, the raw material can be smoothly processed by widening the area where the raw material contacts and reducing the gap between the first and second upper rollers 221 and 222 and the first to third lower rollers 231 to 233.

In the present embodiment, unlike the first embodiment, the position of the guide roller 282d of the second tension adjusting unit 282 is moved between the middle, that is, between the second lower roller 232 and the third lower roller 233. To prevent the lower bolt 272 from tipping and the gap between the upper and lower areas (or length) of the lower bolt 272 to compensate for various problems in accordance with the speed.
