Description

Technical Field

[0001] The invention relates to a wooden drum leather washing machine, belonging to the technical field of leather production equipment. Background Art

[0002] A wooden drum leather washer is a crucial piece of equipment in the leather processing industry, ensuring efficient leather cleaning. It consists of a rotating drum structure equipped with a door to facilitate the entry and exit of leather, and a drive system. Key components of the drive system include a large gear located on one side of the drum and a smaller gear driven by a motor. The wooden drum leather washer operates by placing the leather to be cleaned into the drum, where the cleaning fluid inside cleans the leather from all angles as it rotates.

[0003] Bearing seats are installed at both ends of the wooden drum to support its rotation. When installing the wooden drum, it is important to ensure the coaxiality of the bearing seats at both ends. Coaxiality is a standard for evaluating whether the rotation axis is precisely aligned with the reference axis, which is crucial for the normal and smooth operation of the wooden drum. Traditional bearing seat designs are monolithic structures, providing excellent rigidity and stability. However, for large wooden drums, due to their large size, ordinary metal bearing seats often have difficulty meeting the coaxiality requirements, which complicates the installation process and increases difficulty and cost.

[0004] Furthermore, the wooden drum, while constantly rotating on its own axis, also tends to rotate continuously around a fixed axis, similar to the gyroscope effect. Due to this gyroscope effect and the fixed bearing blocks at both ends, the bearings in the blocks provide rotational support for the drum as it rotates, relying on the bearings to offset the gyroscope effect. This results in severe bearing wear and a short service life.

[0005] Furthermore, the drum body of the existing wooden drum is cylindrical, and the brackets on both sides are connected only by tie bars arranged outside the wooden drum. This structure makes the wooden drum insufficient in strength and stability, and is prone to deformation or damage.

[0006] Therefore, it is necessary to improve the existing wooden drum leather washing machine to improve its use effect. Summary of the Invention

[0007] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a wooden drum leather washing machine which can reduce the difficulty of bearing seat installation, increase the service life of the bearing, and improve the strength and stability of the equipment.

[0008] The wooden drum leather washing machine described in the present invention includes a rotatable wooden drum and an external drive system. The drive system includes a large gear arranged on one side of the wooden drum, and a small gear meshing with the large gear. The small gear is a driving gear. A universal bearing seat and a floating bearing seat are respectively installed at both ends of the wooden drum; the universal bearing seat includes a universal sleeve and a base. The outer side surface of the universal sleeve is provided with a convex spherical surface, and the inner side surface of the base is a concave spherical surface adapted to the convex spherical surface; the floating bearing seat includes a floating sleeve, a fixed ring tube and a high-strength spring. The floating sleeve is located in the fixed ring tube, and the outer periphery of the floating sleeve is connected to the inner wall of the fixed ring tube through multiple high-strength springs.

[0009] The wooden drum of the present invention is respectively equipped with a universal bearing seat and a floating bearing seat at both ends, which are easy to adjust. It not only solves the problem that the fixed bearing seat is difficult to be coaxial when installed, but also the universal bearing seat can change angles with the shaft, and the floating bearing seat can float up and down and left and right, which can fully adapt to the rotation effect when the wooden drum rotates, greatly reducing the degree of bearing wear and improving the service life of the bearing.

[0010] Among them, the universal bearing seat is set at one end of the wooden drum where the large gear is installed. Since the position change of this end is very small, it does not affect the engagement of the large gear and the active pinion. The floating bearing seat is set at the other end of the wooden drum.

[0011] The wooden drum of the present invention is provided with a right bracket and a left bracket on both sides respectively. The right bracket and the left bracket are connected by a plurality of tie bars, and the tie bars are located inside the wooden drum.

[0012] Furthermore, both the right and left brackets are composed of multiple support rods evenly distributed in a circular array, each with multiple tie rod mounting holes along its length. The scattered distribution of tie rods not only significantly enhances the strength and stability of the wooden drum, effectively preventing deformation or damage, and improving the performance and stability of the leather washer, but also, as the drum rotates, the leather, agitated by the tie rods within the drum, comes into full contact with the cleaning fluid, helping to remove stains, grease, and other impurities from the leather surface and enhancing the cleaning effect.

[0013] The convex spherical surface of the universal sleeve of the present invention is provided with transverse strip slots on both sides. The two ends of the base are fixed with limiting shafts, and one end of the limiting shafts on both sides extends into the strip slots.

[0014] Preferably, the width of the strip slot is greater than the diameter of the limiting shaft.

[0015] The inner walls of the universal sleeve and the floating sleeve of the present invention are both provided with oil grooves, the tops of the universal sleeve and the floating sleeve are both provided with oil filling holes, the oil filling holes are communicated with the oil grooves on the inner walls, and sealing bolts are screwed on the oil filling holes.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The wooden drum leather washing machine of the present invention adopts the coordinated cooperation of the universal bearing seat and the floating bearing seat, which makes the installation of the bearing seat more convenient and solves the problem of installation coaxiality; the universal bearing seat can change the angle with the shaft, and the floating bearing seat can float up and down and left and right, which can fully adapt to the rotation effect of the wooden drum, thereby greatly reducing the wear of the bearing and increasing the service life of the bearing.

[0018] 2. The brackets on both sides of the wooden drum are designed as multiple support rods evenly distributed in a circular array. Each support rod has multiple tie rod mounting holes along its length. This structure greatly improves the strength and stability of the wooden drum, can effectively prevent the deformation or damage of the wooden drum, and improves the use effect and stability of the leather washing machine.

[0019] 3. The tensioning bars are scattered and located inside the wooden drum. Under the disturbance of the tensioning bars, the leather is fully in contact with the cleaning liquid during the rotation process, which helps to remove stains, grease and other impurities on the leather surface and improve the cleaning effect.

[0020] 4. The convex spherical surface of the universal sleeve is provided with transverse slots on both sides. Limiting shafts are fixed at both ends of the base, and one end of each limiting shaft extends into the slots. This design makes the universal bearing seat more convenient to install and also improves the stability and service life of the equipment.

[0021] 5. The inner walls of both the universal sleeve and the floating sleeve are equipped with oil grooves and tops with oil filling holes. The oil filling holes are connected to the oil grooves on the inner walls and are sealed with plugging bolts. This design facilitates lubrication and maintenance of the bearing seat, further extending the service life of the bearing and the stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
