Description

A kind of outer quiet inward turning intelligence Tanning drum device
Technical field
The present invention relates to Tanning drum devices, more particularly, to a kind of outer quiet inward turning intelligence Tanning drum device.
Background technology
Currently, leather belongs to one of most important light industry in China, Tanning drum is also used for the various processing of leather.It passes The suspending revolving drum of system carries out leather processing using the mode of drum body rotation, and energy consumption is big;The opening of drum door is closed needs Manual operation, it is time-consuming and laborious, realize automation, it is intelligentized during, be faced with great difficulty.
Invention content
In view of the above problems, the present invention provides a kind of outer quiet inward turning intelligence Tanning drum device.In adding for leather In work process, this Tanning drum can realize automatically opening, being closed for drum door, feed skin and go out skin and offer convenience;And it is working When, lubrication groove rotates and outer shell of drum body does not rotate, it can be achieved that automatic, real-time detect interior temperature, the pH value of bath foam, and reaches energy-efficient Purpose.
The technical solution adopted by the present invention is as follows:
A kind of outer quiet inward turning intelligence Tanning drum device, including rack, drum body, lubrication groove, axis, skull patch plate, engine base, drain Valve, transmission device and complete automatic control system, the bulging body include shell, drum door and drum door lid;The drum door is located at shell On, the drum door lid is located in rack;When work, drum door lid is automatically moved to working position, implements sealing to drum door, fixes, this When drum door close, drum body remain static, lubrication groove and skull patch plate are in rotation status;When entering skin, rotary drum body shell to people Station carries out manually entering skin, after entering skin, outer shell of drum body is rotated to working position, closes drum door;When going out skin, drum door lid and drum door point From outer shell of drum body rotates 360 DEG C of <, reaches out skin position from working position and carries out out skin.
Specifically, this drum door lid and outer shell of drum body separated structure can carry out large scale design, greatly to drum door Facilitate going out skin and entering skin operation for rotary drum, overcome the small drum door of traditional Tanning drum and need artificial the shortcomings that pulling out leather; When work, since outer shell of drum body remains static relative to lubrication groove, i.e., outer shell of drum body is static, and lubrication groove rotation, motor needs band Dynamic load weight mitigates, and energy consumption is reduced, and realizes energy saving;When going out skin, entering skin, shell is rotatable, uses that skin, to enter skin more square Just.
Preferably, the leather can also be set by the automatic throwing leather jacket at the top of rotary drum carries out entering skin automatically in working position.
Specifically, in entering skin operating process, there are two types of modes of operation, and bulging body can both be selected to go to artificial position into pedestrian Work enters skin, and also the optional leather jacket of throwing automatically, which is set, in working position into skin, enter skin automatically and need to be equipped with throwing skin automatically at the top of rotary drum Device.
Preferably, the drum door is divide into upper part and lower part, and the drum door portion of covering is equipped with inlet valve, air bleeding valve, pressurizing valve, vacuum Valve closes door cylinder and seal strip groove;The inlet valve is equipped with feeding device;The pressurizing valve is equipped with air compressor machine;The vacuum valve Equipped with vacuum pump;The seal strip groove is one week peripheral around drum door lid upper inside surface;Drum door lid lower part is equipped with distributing trough, The distributing trough is equipped with charging aperture.
Specifically, when drum door is covered in " drum door is opened " position, start drum door lid and move at " drum door pass ", close door cylinder pass It closes and drum door is sealed, is fixed, at this moment rotary drum is in " working position ";Charging valve is opened, the chemical agent warp in feeding device The distributing trough of drum door lid lower part is dispersed in drum, it can be achieved that chemical agent is dispersed in bath foam;Described in adjusting Air bleeding valve, pressurizing valve and vacuum valve make environmental pressure in drum reach normal pressure, positive pressure or negative pressure, change the physical rings of leather processing Production efficiency is improved in border, promotes leather quality.As needed, drum door needs to reach artificial position or goes out Pi Weishi, closes gas first Cylinder starts, and drum door lid is promoted, and then drum door lid moves at " drum door is opened " and stops, at this point, drum door lid is detached with drum door, drum is external Shell rotation reaches required position.
Preferably, it is equipped with lubrication groove at left and right sides of the outer quiet inward turning intelligence Tanning drum device, the lubrication groove passes through axis It is fixed in rack, the lubrication groove outer diameter≤internal diameter of drum.
Specifically, using both sides Synchronous Transmission, staring torque is big, can adjust and export automatically according to demand torque.
Preferably, the lubrication groove is equipped with aperture, and at least three pieces skull patch plate is equipped between the left and right sides lubrication groove, described Skull patch plate is crossed with radial between the lubrication groove of both sides, the outer edge of skull patch plate close to the internal wall of drum without contacting, skull patch plate Height is the 5%-30% of the internal diameter of drum.
Specifically, when lubrication groove rotates, skull patch plate can be driven to rotate, and the movement of skull patch plate by leather and bath foam ceaselessly Agitation so that leather and bath foam are sufficiently mixed, and when skull patch plate moves from the bottom up, leather are driven to reach the middle and upper part of rotary drum, Leather beats leather from high position downslide due to dead weight, along skull patch plate so that medicament fully penetrated in bath foam to skin It removes from office in fiber, improves leather quality.
