Description

Technical Field

[0001] This utility model relates to the field of leather fatliquoring technology, specifically a high-emulsification leather fatliquoring centrifuge. Background Technology

[0002] The "high emulsification" in a high-emulsification leather fatliquoring centrifuge refers to the emulsifying properties of the fatliquoring agent, meaning that the fatliquoring agent (usually an oil-based substance) mixes well with water to form a stable emulsion. This emulsification effect is crucial for the leather fatliquoring process because it ensures even distribution of the oils and better penetration into the leather fibers. In a high-emulsification leather fatliquoring centrifuge, the machine uses centrifugal force to evenly distribute the emulsified fatliquoring agent throughout the leather. The high-emulsification fatliquoring agent not only better covers the leather surface but also ensures deep penetration of the oils, reducing oil loss or shedding in subsequent processes.

[0003] In traditional leather fatliquoring processes, mechanical centrifugal drum equipment is typically used. These drums primarily utilize the centrifugal force generated by the high-speed rotation of the drum to evenly distribute the fatliquoring solution across the leather surface. However, traditional mechanical centrifugal drum equipment has several shortcomings in practical applications, resulting in unsatisfactory fatliquoring effects, especially in the treatment of highly emulsified leathers, where it exhibits significant limitations. Traditional centrifugal drum equipment, relying solely on centrifugal force, struggles to achieve a sufficiently uniform distribution of the fatliquoring solution on the leather surface. Due to the directional nature of centrifugal force, during rotation within the drum, the liquid accumulates primarily at the surfaces subjected to force, while the inner sides or thicker areas of the leather remain untouched, leading to uneven fatliquoring and negatively impacting leather quality.

[0004] In view of this, we will study and improve the existing problems and provide a high emulsifying leather fatliquoring centrifuge to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0005] This invention aims to solve the problems of low efficiency and uneven fatliquoring in existing leather fatliquoring equipment during the process of emulsifying leather fatliquoring, and provides a high-emulsification leather fatliquoring centrifuge to improve the uniformity and efficiency of fatliquoring.

[0006] Therefore, the technical solution adopted by this utility model is as follows: a high-emulsification leather fatliquoring centrifuge, comprising: a support frame, a drive seat, and a centrifuge drum. An adjusting shaft seat is fixedly mounted on the surface of the support frame for adjusting the tilt angle of the equipment to optimize the fatliquoring effect. The drive seat is rotatably mounted inside the adjusting shaft seat and drives the centrifuge drum to rotate centrifugally via a main shaft disc. The motor, providing power, is connected to the main shaft disc through a transmission mechanism to drive the centrifuge drum to rotate. Several ultrasonic oscillators are provided on the surface of the centrifuge drum to generate oscillations, further enhancing the fatliquoring effect.

[0007] In a preferred embodiment, this invention can be further configured such that: the slip ring seat is fixedly mounted on the bottom surface of the drive seat, and the electrode shaft is electrically connected to the ultrasonic oscillator, continuously providing power to the ultrasonic oscillator during centrifugal rotation. Through the interaction between the ultrasonic oscillator and centrifugal force, the fatliquoring solution on the leather surface is evenly distributed, improving the fatliquoring effect.

[0008] By adopting the above technical solution, the uniformity of leather fatliquoring is significantly improved by combining centrifugal force and oscillation. In particular, it can effectively avoid uneven fatliquoring, especially in the process of fatliquoring highly emulsified leather.

[0009] In a preferred embodiment, the present invention can be further configured such that the oscillation frequency and amplitude of the ultrasonic oscillator can be adjusted by a control system to adapt to the fatliquoring requirements of different leather thicknesses, ensuring precise control of the fatliquoring effect.

[0010] By adopting the above technical solution, the oscillation parameters can be flexibly adjusted according to the leather material and thickness to ensure that the fatliquoring requirements of different types of leather are met and to further improve the fatliquoring effect.

[0011] In a preferred embodiment, the present invention can be further configured such that the centrifuge tube fixes the leather material inside by a permanent magnet device, ensuring that the leather material will not shift or fall off during rotation, thus ensuring the stability of the fatliquoring process.

[0012] By adopting the above technical solution, the leather material can be firmly fixed during the fatliquoring process, avoiding unnecessary displacement during centrifugal rotation, thereby ensuring the uniform distribution of the fatliquoring solution.

[0013] In a preferred embodiment, the present invention can be further configured such that the tilt angle of the centrifuge tube can be adjusted by adjusting the shaft seat, so that the centrifuge tube rotates in a tilted state, thereby further improving the uniformity of fat addition, which is especially suitable for processing leather of different thicknesses.

[0014] By adopting the above technical solution and utilizing tilting and rotating fatliquoring, leathers of different thicknesses can be processed more effectively, ensuring the flexibility and efficiency of the fatliquoring process.

[0015] This invention significantly improves the uniformity and efficiency of leather fatliquoring by combining centrifugal rotation and oscillation. It is suitable for fatliquoring treatment of various types of leather, and has excellent fatliquoring effect, especially for highly emulsifiable leather. It is easy to operate and maintain.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] 1. By combining centrifugal rotation and oscillation, this utility model can effectively improve the uniformity of leather fatliquoring. Especially when processing highly emulsified leather, the combination of ultrasonic oscillator and centrifugal force ensures the uniform distribution of fatliquoring solution on the leather surface, avoiding the problems of uneven fatliquoring and insufficient penetration of fatliquoring solution that are easy to occur in traditional fatliquoring methods, thereby significantly improving fatliquoring efficiency.

[0018] 2. In this utility model, an adjustable drive seat tilting structure and a permanent magnet device are used to firmly fix the leather material inside the centrifuge drum, ensuring the stability of the leather during rotation. At the same time, the control system adjusts the oscillation frequency and amplitude, enabling the equipment to adapt to leather of different thicknesses and materials for fatliquoring treatment, further improving the adaptability and operational flexibility of the equipment, enhancing production efficiency and reducing the difficulty of equipment maintenance.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the high-emulsification leather fatliquoring centrifuge provided by this utility model.

[0029] Combination Figures 1-4 As shown, the high emulsifying leather fatliquoring centrifuge provided by this utility model, in one embodiment, includes: a support frame 100, a drive seat 200, and a centrifuge drum 300. The support frame 100 is used to stabilize the entire device, and an adjusting shaft seat 110 is fixedly mounted on the surface of the support frame 100 for adjusting the installation angle of the drive seat 200 to adapt to different working conditions.

[0030] The drive base 200 is rotatably mounted inside the adjusting shaft base 110 and is fixedly connected to the bottom end of the centrifuge cylinder 300 via the main shaft disk 220. The main shaft disk 220 can drive the centrifuge cylinder 300 to rotate on the top surface of the support frame 100. The motor 210 is mounted inside the drive base 200 and transmits power to the main shaft disk 220 through a transmission mechanism, causing it to rotate. The output end of the motor 210 is connected to the main shaft disk 220 through a transmission structure. The transmission connection may include conventional structures such as couplings and drive shafts, used to transmit the torque generated by the motor 210 to the main shaft disk.

[0031] The centrifuge cylinder 300 is mounted on the top surface of the support frame 100 and fixed to the drive base 200 by the spindle disk 220. When the motor 210 starts, it drives the spindle disk 220 to rotate, causing the centrifuge cylinder 300 to rotate at high speed. Several ultrasonic oscillators 310 are evenly distributed on the surface of the centrifuge cylinder 300 to generate oscillations, thereby improving the emulsification effect on the leather surface during the fatliquoring process. An opening is provided at the top of the centrifuge cylinder 300, the diameter of which is smaller than the maximum inner diameter of the centrifuge cylinder 300, to limit the upward flow and splashing of the fatliquoring liquid, thus improving operational safety.

[0032] The slip ring seat 230 is fixedly installed on the bottom surface of the drive seat 200. An electrode shaft 231 is provided on the inner side of the slip ring seat 230. The top end of the electrode shaft 231 passes through the main shaft disk 220 and is electrically connected to the end of the ultrasonic oscillator 310. The slip ring seat 230 and the electrode shaft 231 are used to provide power to the ultrasonic oscillator 310 during the rotation of the centrifuge cylinder 300. Several elastic electrode strips are provided on the inner wall of the slip ring seat 230. These electrode strips slide in contact with the electrode rings provided on the surface of the electrode shaft 231 to achieve a stable power supply.

[0033] The centrifuge drum 300 is made of ferromagnetic material and uses compatible permanent magnets to attract and fix the leather material. During use, the leather material inside the centrifuge drum 300 is fixed to its inner side by the permanent magnets, ensuring the stability of the leather material during rotation. An overflow cover 320 is detachably connected to the top of the centrifuge drum 300 to prevent liquid from spilling during rotation and ensure operational safety.

[0034] In a preferred embodiment, the number of ultrasonic oscillators 310 is several, and they are evenly distributed circumferentially on the surface of the centrifuge cylinder 300. All ultrasonic oscillators 310 are electrically connected to the electrode shaft 231 in parallel to ensure that each ultrasonic oscillator 310 works synchronously, thereby effectively improving the uniformity of leather fatliquoring.

[0035] By having several electrode strips arranged on the surface of the slip ring seat 230 slide against the electrode shaft 231, it is ensured that all ultrasonic oscillators 310 can continuously obtain a stable power supply when the centrifuge cylinder 300 rotates.

[0036] To improve the fatliquoring effect, the drive seat 200 can be adjusted to a certain tilt angle, so that the centrifuge cylinder 300 rotates in a tilted state, thereby making the fatliquoring of the leather surface more uniform and adapting to the fatliquoring needs of leather materials of different thicknesses.

[0037] The input terminal of the ultrasonic oscillator 310 is electrically connected to a control system, which is used to adjust the frequency and amplitude of the oscillation. This control system allows for precise control of the fatliquoring process based on the different thicknesses and materials of the leather, thereby improving the emulsification properties of the fatliquoring solution.

[0038] This invention improves the emulsification of fatliquoring solution by combining rotation and oscillation, making it suitable for fatliquoring treatment of various types of leather, especially for leather with high emulsification properties. The equipment has a simple structure, is easy to maintain and operate, and is suitable for industrial production.

[0039] Working principle and usage process of this utility model:

[0040] Working principle:

[0041] This utility model of a highly emulsifying leather fatliquoring centrifuge achieves efficient fatliquoring treatment of leather through the coordinated operation of the support frame 100, drive base 200, and centrifuge drum 300. Upon startup, the motor 210 drives the main shaft disk 220 to rotate, which in turn drives the centrifuge drum 300 to rotate at high speed. The rotation of the centrifuge drum 300 generates centrifugal force, ensuring uniform force distribution on the leather surface and accelerating the distribution and penetration of the fatliquoring solution.

[0042] Meanwhile, multiple ultrasonic oscillators 310 mounted on the surface of the centrifuge drum 300 are connected to electrode strips via electrode shafts 231, continuously generating oscillations during rotation. The combination of oscillation and centrifugal force further enhances the fatliquoring effect, ensuring the leather surface fully and evenly absorbs the fatliquoring solution. The control system is used to adjust the oscillation frequency and amplitude of the ultrasonic oscillators 310 to adapt to the fatliquoring requirements of different leather thicknesses and materials.

[0043] To ensure uniform fatliquoring, the drive seat 200 can be adjusted to a certain tilt angle, allowing the centrifuge drum 300 to rotate centrifugally in an inclined state, further improving the fatliquoring effect on the leather surface, and is particularly suitable for treating leathers of different thicknesses.

[0044] Usage process:

[0045] Equipment preparation

[0046] Secure the equipment to the work platform, ensuring the support frame 100 is stable. Adjust the angles of the drive seat 200 and the centrifuge cylinder 300 as needed, and adjust the tilt of the drive seat 200 by adjusting the shaft seat 110 to ensure the equipment can adapt to different grease-adding process requirements.

[0047] Leather fixing

[0048] The leather material to be processed is placed inside the centrifuge drum 300, and the leather material is firmly fixed to the inside of the centrifuge drum 300 by permanent magnet patches to ensure that the leather material will not shift or deviate during the rotation process.

[0049] Add fatliquoring solution

[0050] Add an appropriate amount of fatliquoring solution into the centrifuge drum 300 to ensure that the leather material can fully contact the fatliquoring solution.

[0051] Start the device

[0052] The motor 210 is started, which drives the centrifuge drum 300 to rotate at high speed through the spindle disk 220. Under the action of centrifugal force, the fatliquoring solution is evenly distributed on the leather surface. At the same time, the control system is activated, which provides power to the ultrasonic oscillator 310 through the electrode shaft 231, causing the ultrasonic oscillator 310 to generate high-frequency oscillations. This, together with the centrifugal force, improves the fatliquoring effect.

[0053] Adjusting the oscillation frequency and amplitude

[0054] Depending on the thickness and material of the leather, the oscillation frequency and amplitude of the ultrasonic oscillator 310 are adjusted via the control system. For thicker leather, the oscillation frequency can be appropriately increased to ensure that the fatliquoring solution can penetrate deeply into the leather.

[0055] Monitoring of fat addition process

[0056] During the grease application process, monitor the rotation speed and oscillation frequency to ensure smooth operation. If necessary, the tilt angle of the equipment can be adjusted by changing the bearing seat 110 to further optimize the grease application effect.

[0057] Fat addition complete

[0058] After the fatliquoring process is complete, stop the operation of motor 210 and ultrasonic oscillator 310, and remove the fatliquored leather. If the leather surface is evenly fatliquored, it indicates that the fatliquoring effect is good.

[0059] Cleaning equipment

[0060] After the grease addition is completed, remove the overflow cover 320 of the centrifuge drum 300, clean out the residual grease inside, and maintain and check the condition of each component to ensure that the equipment can continue to operate normally.

[0061] Through the above process, this invention achieves efficient and uniform leather fatliquoring treatment, and is especially suitable for leather processing that requires high emulsification.
