Description

Bagged spring manufacturing device

Technical Field

Background

In the manufacturing process of the bagged spring for the mattress, the process is that the steel wire is wound into the spring, then the spring is compressed to the preset size, and then the spring is conveyed to the welding mechanism by the spring conveying device and is welded with the non-woven fabric to form the bagged spring.

For example, in the prior art, the production time of each production beat of each station of the bagged spring is inconsistent, and the spring rolling speed of the machine head is generally slower than the compression and conveying time, so that the overall beat of the bagged spring manufacturing device is slower, and the production efficiency is lower.

For example, in the prior art, the bagged spring manufacturing equipment has a complex structure, is arranged among stations in a scattered manner, and has poor transmission continuity and stability.

For example, in the prior art, after the spring is wound and cut into a predetermined size, the spring is generally transmitted to the spring compression assembly by the turntable-type switching device to be compressed, and the spring is easily plastically deformed during the compression process, which results in the reduction of product quality.

For example, in the prior art, it is common to perform a reciprocating motion by driving a compression mechanism to compress a spring, but since the compression mechanism must perform a backward motion along the same path after compressing the spring, the time per tact increases, decreasing the work efficiency. Furthermore, in order to achieve the backward movement in the prior art, a crank-slider mechanism is generally required to be formed by a turntable, a connecting rod, a slider, a guide rail and the like, and a corresponding spring receiving and positioning structure is arranged, so that on one hand, the occupied space is generally increased due to components required for performing the reciprocating motion, the requirement on the construction space along the axis is remarkably increased, and on the other hand, the structure of the combination of the turntable, the connecting rod, the slider, the guide rail and the spring receiving and positioning structure is relatively complex as a whole. Furthermore, the prior art spring compression assemblies are functionally simple and require relatively complex transition or auxiliary structures when mated with other functional modules.

For example, in the prior art, the spring conveying bagging mechanism has a plurality of defects in use: (1) the guide plate in each group of synchronous belt assemblies consists of two parts, namely a front guide plate and a rear guide plate, the front guide plate is inclined relative to the rear guide plate, so that a V-shaped area and a flat area are formed in the inlet area of the two groups of synchronous belts, a spring is extruded and deformed after entering the synchronous belts, but the phenomena of spring dislocation, inclination, uneven elastic stress and the like easily occur in the way of conveying and compressing the spring; (2) the synchronous belt is easy to jump; (3) the pushing base structure is not easy to adjust and unstable, and is easy to vibrate and deform when the machine runs at high speed.
