A circulating brazing device for insulating crepe paper tubes

Abstract

The invention relates to a circulating solder bar feeding device used for insulated corrugated paper tubes. The circulating solder bar feeding device comprises a rack. A solder bar extraction chain, transferring chains and a solder bar feeding chain are arranged on the rack. A rotary driving mechanism is arranged between a first chain wheel shaft of the solder bar extraction chain and the rack. Alimiting plate and at least two guide frames are arranged on one side of the solder bar extraction chain, and at least two first elastic shifting mechanisms are arranged on the other side of the solder bar extraction chain. A first transmission mechanism is arranged between a third wheel shaft of the adjacent transferring chains and the rotary driving mechanism. A second transmission mechanism isarranged between a fifth chain wheel shaft and a second chain wheel shaft on the solder bar feeding chain. An arc-shaped guide plate is arranged between a chain protection frame of the solder bar feeding chain and the transferring chains, and second elastic shifting mechanisms are arranged between the chain protection frame of the solder bar feeding chain and the fifth chain wheel shaft. The solder bar extraction chain, the transferring chains and the solder bar feeding chain are in linking transmission, stable transferring of solder bars is ensured under the effect of the multiple elastic shifting mechanisms, and the solder bars are cyclically fed at intervals, so that the number of needed solder bars is reduced, the occupied area in a workshop, energy consumption, control difficulty andcost are reduced, and the continuous production efficiency is improved.

Description

technical field [0001] The invention relates to a circular brazing device for insulating crepe paper tubes, belonging to the technical field of insulating crepe paper tube production. Background technique [0002] Insulating corrugated paper tube has good mechanical and insulating properties. It is made of corrugated insulating paper and then coated with glue to roll the tube. In order to obtain a tube shape with a fixed inner and outer diameter and easy to roll, the insulating corrugated paper tube Inserting brazing rods can be used, and the brazing rods are wrapped with insulating crepe paper and rolled up and pasted continuously, and then the brazing rods are removed to obtain a hollow tubular structure. The strips are heavy, and manual drawing and brazing is time-consuming and labor-intensive, and it is easy to damage the defect of the insulating paper tube.

[0002] Insulating corrugated paper tube has good mechanical and insulating properties. It is made of corrugated insulating paper and then coated with glue to roll the tube. In order to obtain a tube shape with a fixed inner and outer diameter and easy to roll, the insulating corrugated paper tube Inserting brazing rods can be used, and the brazing rods are wrapped with insulating crepe paper and rolled up and pasted continuously, and then the brazing rods are removed to obtain a hollow tubular structure. The strips are heavy, and manual drawing and brazing is time-consuming and labor-intensive, and it is easy to damage the defect of the insulating paper tube. Mechanical drawing and stacking is used, and after a certain amount is accumulated, it is transported to the brazing process, resulting in the need for more auxiliary equipment and occupying the workshop. Larger, the transportation cost and the difficulty of transporting manually operated forklifts are relatively large. In order to ensure the continuous production of insulating corrugated paper tubes, the number of brazing rods is relatively large, and it is also necessary to be equipped with a separate continuous interval control for the upper brazing device, resulting in high energy consumption, difficult control, significant increase in production cost, and decline in production efficiency
