Description

Technical Field

[0001] This utility model relates to the field of module belt technology, and in particular to a wear-resistant sound-absorbing module belt. Background Technology

[0002] Roller module belts are increasingly widely used in logistics sorting. Roller module belts, such as... Figure 1-2 As shown, the assembly includes a chain plate 1.1, a long roller 1.3, and a steel pin 1.2. Both the chain plate 1.1 and the long roller 1.3 are injection molded. The chain plate 1.1 has a slot for mounting the long roller 1.3, which is inserted into the slot. The long roller 1.1 has a through hole for the steel pin 1.2 to pass through. The side walls of the slots on both sides of the long roller 1.1 have mounting grooves for the steel pin 1.2 to enter. The middle part of the steel pin 1.2 passes through the through hole of the long roller 1.1, and both ends extend into the mounting grooves on the same side. The long roller 1.3 can rotate around the steel pin 1.2. To ensure a relatively loose fit between the long roller 1.3 and the steel pin, the injection molding process often leaves a large gap. When a large number of rollers are rolling, they will generate a lot of noise, which can cause injury to production operators.

[0003] Therefore, this utility model proposes a wear-resistant sound-absorbing module belt to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wear-resistant sound-absorbing module belt that reduces the process requirements for long rollers and reduces the noise generated during operation.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a wear-resistant sound-absorbing module belt, including a chain plate, long rollers and steel pins. The chain plate has a groove for installing long rollers. The long rollers are inserted into the groove of the chain plate and are rotatably connected to the chain plate through the steel pins. Its innovation is that the wear-resistant sound-absorbing module belt also includes a silent ring and a bushing.

[0006] The bushing has two bushings, which are respectively set at both ends of the long roller. The long roller has a stepped hole, the steel pin passes through the stepped hole, and the bushing is sleeved on the outside of the steel pin and embedded in the stepped hole.

[0007] The silencing ring is disposed inside the stepped hole and sleeved on the outside of the steel pin, and the inner wall surface of the silencing ring has a wavy protrusion.

[0008] Furthermore, the bushing is interference-fitted with the long rollers.

[0009] Furthermore, the silent ring is interference-fitted with the long roller.

[0010] Furthermore, the wavy protrusion is composed of several conical protrusions arranged in a matrix, with the tips of the conical protrusions transitioning into an arc shape.

[0011] Furthermore, there is an arc-shaped recess between two adjacent conical protrusions.

[0012] Furthermore, the connection between the arc-shaped recess and the conical protrusion is smoothly transitioned.

[0013] The advantages of this utility model are:

[0014] The wear-resistant sound-absorbing module of this utility model utilizes bushings to isolate long rollers from steel pins, reducing the process requirements for long rollers and improving production efficiency. On the other hand, by setting a silencing ring inside the stepped hole, the wavy protrusions on the inner surface of the silencing ring reflect the noise generated during operation multiple times between the protrusions, gradually consuming the propagation energy and achieving a noise reduction effect, thus improving the working environment for operators.

[0015] This utility model uses an interference fit to install the bushing and the silencer ring, which simplifies the operation and makes installation convenient.

[0016] The wave-shaped protrusion of this invention is composed of several conical protrusions arranged in a matrix. The tips of the conical protrusions are rounded. This structure of conical protrusions makes it easier to form reflections in the annular space inside the silencing ring, increasing the number of reflections and thus improving the noise reduction effect.

[0017] The present invention has an arc-shaped recess between two adjacent conical protrusions, which can effectively increase the reflective surface, increase the number of reflections, and further improve the noise reduction effect.

[0018] The smooth transition between the arc-shaped recess and the conical protrusion in this invention reduces the diffraction effect of sound waves and improves the noise reduction effect. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] like Figure 3-4 As shown, this embodiment provides a wear-resistant sound-absorbing module belt, including a chain plate, a long roller 2.1, a steel pin, a silent ring 2.3, and a bushing 2.2.

[0026] The chain plate has a slot for mounting long rollers 2.1. The long rollers 2.1 are inserted into the slot of the chain plate and are rotatably connected to the chain plate by steel pins.

[0027] There are two bushings 2.2, which are respectively set at both ends of the long roller 2.1. The long roller 2.1 has a stepped hole, and the steel pin passes through the stepped hole. The bushing 2.2 is sleeved on the outside of the steel pin and embedded in the stepped hole of the long roller 2.1. The bushing 2.2 and the long roller 2.1 are connected by an interference fit.

[0028] A mute ring 2.3 is positioned inside the stepped hole and fitted onto the outside of the steel pin. The mute ring 2.3 is interference-fitted with the long roller 2.1. The inner wall of the mute ring 2.3 has wavy protrusions, composed of several conical protrusions 2.3.1 arranged in a matrix. The tips of the conical protrusions 2.3.1 have rounded transitions. This structure of conical protrusions facilitates reflection within the annular space formed between the mute ring 2.3 and the steel pin, increasing the number of reflections and thus improving noise reduction. To further increase the reflective surface and the number of reflections, a rounded recess 2.3.2 is provided between adjacent conical protrusions 2.3.1. The connection between the rounded recess 2.3.2 and the conical protrusion 2.3.1 is smooth, reducing sound wave diffraction and enhancing noise reduction.

[0029] The wear-resistant sound-absorbing module of this utility model utilizes bushings to isolate long rollers from steel pins, reducing the process requirements for long rollers and improving production efficiency. On the other hand, by setting a silencing ring inside the stepped hole, the wavy protrusions on the inner surface of the silencing ring reflect the noise generated during operation multiple times between the protrusions, gradually consuming the propagation energy and achieving a noise reduction effect, thus improving the working environment for operators.
