AI Technical Summary
The existing leather dyeing drums do not provide enough force to tumble the leather, which affects the dyeing effect.
A long, hollow shell is installed inside the drum. The concave arc surface lifts the leather and encases it in water before it is slammed onto the convex arc surface and hemispherical protrusions, thus increasing the slamming force.
By increasing the force of the pounding, the dyeing effect of the leather was improved.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to leather dyeing technical field, concretely relates to a leather dyeing drum. BACKGROUND
[0002] Leather is placed in the drum and dyed, the existing drum is provided with a baffle, and the leather slides along the baffle when the drum rotates, so that the beating force is small and is not conducive to the dyeing of the leather. UTILITY MODEL CONTENTS
[0003] The utility model discloses a leather dyeing drum that can increase the beating force of the leather when the drum rotates.
[0004] The utility model discloses a leather dyeing drum, including the drum body, be equipped with the open and close access door on the drum body, the inside of drum body is evenly spaced and is provided with long strip hollow shell along the circumference, the bottom of long strip hollow shell is connected with the lateral wall of drum, and the both ends of long strip hollow shell are connected with the both ends of drum, and the side of each long strip hollow shell is arranged into the concave arc surface, and the other side surface of long strip hollow shell and the head of long strip hollow shell are arranged into the convex arc surface, and the side of long strip hollow shell both sides and the head connection place is smooth transition, and the both ends of the head of long strip hollow shell are provided with the stand, and the tangent line of the connection place of concave arc surface and the head convex arc surface is parallel with the stand, and the end of stand is provided with the cross bar away from long strip hollow shell.
[0005] The principle of the above technical solution is that in the rotating process of the drum, the leather and water in the drum are scooped up by the concave arc surface of the long strip hollow shell, when the water and leather in the concave arc surface are continuously lifted, the leather flows out of the concave arc surface of the long strip hollow shell along with the water flow, the end of the leather flowing out first is hung on the cross bar under the action of inertia, the other end of the leather is still in the concave arc surface, then the water in the concave arc surface flows to the leather between the cross bar and the head of long strip hollow shell, and the leather falls off with a part of water, and the leather with water has greater beating force.
[0006] Further, the number of long strip hollow shells is four, when one of the long strip hollow shells rotates to the top, one long strip hollow shell is below, so that the leather falling off beats on the side surface of the long strip hollow shell provided with the convex arc surface, instead of beating on the water surface, so that the beating effect is better.
[0007] Further, the side surface of the long strip hollow shell provided with the convex arc surface is uniformly provided with the semispherical convex, and the beating effect is better when the leather beats on the semispherical convex.
[0008] The leather dyeing rotating drum disclosed by the utility model has the advantages that when the leather falls from a high place, the leather can wrap water and fall on the side of the long-strip-shaped hollow shell which is provided with an outward convex arc surface and collide with the semispherical protrusions arranged thereon, so that the falling effect is good and the dyeing is facilitated.

[0012] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and the preferred embodiments.
[0013] Embodiment 1:
[0014] As shown in Figure 1 , 2 , 3, the utility model discloses a kind of leather dyeing rotating drum, including rotating drum 1 body, rotating drum 1 body is equipped with the entrance and exit door 3 of openable and closable, rotating drum 1 body inside is evenly spaced along the circumference and is provided with four long-strip-shaped hollow shell 2, the bottom of long-strip-shaped hollow shell 2 is connected with the side wall of rotating drum 1, the two ends of long-strip-shaped hollow shell 2 are connected with the two ends of rotating drum 1, the side of each long-strip-shaped hollow shell 2 is provided as concave arc surface, the other side of long-strip-shaped hollow shell 2 and the head of long-strip-shaped hollow shell 2 are provided as outward convex arc surface, the side of long-strip-shaped hollow shell 2 being provided as outward convex arc surface is evenly provided with semispherical protrusion 6, the side of long-strip-shaped hollow shell 2 and head connection place of two sides is smooth transition, the head of long-strip-shaped hollow shell 2 two ends is provided with stand 4, the tangent line of concave arc surface and head outward convex arc surface connection place is parallel with stand 4, the end of stand 4 away from long-strip-shaped hollow shell 2 is provided with horizontal rod 5.
[0015] The principle of the technical scheme is that the leather 7 and water in the rotating drum 1 are scooped up by the inner concave arc surface of the long hollow shell 2 during the rotation of the drum 1, when the water and the leather 7 in the inner concave arc surface are continuously lifted, the leather 7 flows out of the inner concave arc surface of the long hollow shell 2 along with the water flow, the end of the leather 7 flowing out first is hung on the cross rod 5 under the action of inertia, the other end of the leather 7 is still in the inner concave arc surface, then the water in the inner concave arc surface flows to the leather 7 between the cross rod 5 and the head of the long hollow shell 2, the leather 7 falls with the water, the fallen leather 7 wraps the water and falls and hits on the side of the long hollow shell 2 provided with the outer convex arc surface, collides with the semispherical protrusions 6 arranged thereon, and has good falling and hitting effect, which is beneficial to dyeing.
