Description

Leather processing device for shoemaking Technical Field The present utility model relates to a treatment device, and more particularly, to a leather treatment device for shoemaking. Background The leather processing device for shoemaking is a key device for carrying out chemical treatment (tanning) on leather raw materials in the shoemaking process, and aims to improve the softness, durability, aesthetic property and functionality of leather, so that the leather meets the requirements of footwear products, leather tanning is a key link of leather processing, animal hides (collagen fibers) are converted into soft, durable and non-perishable leather through chemical treatment, a common softening method is a chrome tanning method, the pretreated hides are soaked by chrome tanning liquid, then the pH value is adjusted to 3.8-4.2, so that chromium salt is combined with collagen, but the fact is found in practical operation, the pH adjustment stage must be performed slowly, that is, the adjustment liquid needs to be continuously mixed with the chrome tanning liquid to form the preparation liquid with different pH values, and then the preparation liquid enters the peltry soaking equipment from low pH value to high pH value, otherwise, the peltry is easily softened unevenly or excessively soft outside and hard inside, because the preparation liquid has corrosiveness, the liquid flow cannot be directly controlled by using precise equipment, the manual control of workers is usually required in the prior art, thus having great potential safety hazard, and therefore, a leather processing device for shoemaking is required, which can automatically continuously mix the chrome tanning liquid and the adjustment liquid to form the preparation liquid with different pH values after the chrome tanning liquid soaks the peltry. In combination with the above, it is a matter of the present application how to automatically mix the chrome tanning liquor and the adjusting liquor to form a preparation liquor of different pH after soaking the pelt in the chrome tanning liquor. Disclosure of utility model Aiming at the defects existing in the prior art, the leather processing device for shoemaking is provided, and the device can automatically mix the chrome tanning liquid and the adjusting liquid continuously to form the modulating liquid with different pH values after the chrome tanning liquid soaks the peltry. In order to achieve the aim, the technical scheme is that the leather processing device for shoemaking comprises a frame, a processing box, a main tank body component, an auxiliary tank body component, a driving component and a buffer tank body component, wherein the main tank body component, the auxiliary tank body component, the driving component and the buffer tank body component are all arranged on the frame, the main tank body component is connected with the auxiliary tank body component, the main tank body component and the auxiliary tank body component are connected with the driving component, the buffer tank body component is connected with the driving component, and the processing box is connected with the buffer tank body component; when liquid exists in the main tank body assembly, the liquid in the auxiliary tank body assembly cannot enter the buffer tank body assembly. In summary, the technical scheme has the advantages that the main tank body component is used as a core storage unit, chrome tanning liquid is filled in the main tank body component and is directly used for preliminary treatment of leather, the auxiliary tank body component is used for storing pH adjusting liquid and is linked with the main tank body component and the auxiliary tank body component through a connecting pipeline, the driving component is directly connected with the main tank body component and the auxiliary tank body component, liquid in the main tank body component and the auxiliary tank body component can be controlled to enter the buffer tank body component through a pump or an air pressure system of a facility, the buffer tank body component is used as an intermediate transition container, and after the driving component receives the liquid from the main tank body component or the auxiliary tank body component and stabilizes the pressure, the liquid is conveyed to the treatment tank for leather treatment; When chrome tanning liquid is arranged in the main tank body assembly, a passage between the auxiliary tank body assembly and the buffer tank body assembly is cut off, so that the driving assembly can only bring the chrome tanning liquid in the main tank body assembly into the buffer tank body assembly, and after the liquid in the main tank body assembly is exhausted, a small part of chrome tanning liquid is left in the buffer tank body assembly, most of chrome tanning liquid enters the treatment tank to perform preliminary operation on the peltry, at the moment, pH adjusting liquid in the auxiliary tank body assembly can gradually
