Description

Technical Field

[0001] The utility model belongs to the technical field of heat insulation cotton processing facility design, in particular to an automatic edge wrapping machine for heat insulation cotton. Background Art

[0002] As a common thermal insulation material, thermal insulation wool is widely used in many fields such as construction, industrial equipment, and transportation. Its main function is to reduce the transfer of heat, thereby achieving the effect of energy saving and maintaining temperature. Thermal insulation wool is usually made of glass fiber, mineral wool, polyester fiber and other materials, which have good thermal insulation properties and certain mechanical strength, and can withstand certain pressure and temperature.

[0003] Both sides of the thermal insulation cotton need to be edged. The existing edge-binding method is to leave a part of excess length when processing the bottom fabric of the thermal insulation cotton, and then fold this part of the fabric to fit the side of the thermal insulation cotton, and fix it with glue. This method will produce some resistance when folding because the fabric itself has a certain elasticity, making the folding corner arc-shaped, making it difficult to achieve a neat folding, affecting the folding effect. At the same time, the existing device is difficult to achieve automatic and stable edge binding of the thermal insulation cotton material during movement, the device operation is not smooth enough, and the required processing time is long. Utility Model Content

[0004] The utility model aims to provide an automatic edge wrapping machine for heat-insulating cotton to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic edge wrapping machine for heat-insulating cotton comprises two parallel feeding devices, a base device is arranged at the bottom of the feeding device, and two scoring devices are symmetrically arranged on both sides of the base device; the base device comprises a processing table, and two glue applicators are symmetrically arranged on both sides of the processing table, a bending frame is arranged in front of the glue applicator, a drying box is arranged in front of the bending frame, and a heating wire is installed in the middle of the drying box; the scoring device comprises a bracket, and two limit rods are symmetrically fixedly arranged on the top of the bracket, a support frame is slidably arranged on the inner side of the limit rod, a spring is fixedly arranged on the outer side of the support frame, and a scoring wheel is rotatably arranged on the inner side of the support frame.

[0007] Furthermore: the feeding device includes a fixed frame, and two feeding rollers are rotatably arranged on the top of the fixed frame, a gear is arranged on one side of the feeding roller, and a motor is installed on one side of the gear.

[0008] Furthermore: the gear is connected to the feed roller with a flat key, and the motor is connected to the fixing frame with bolts.

[0009] Furthermore: the bending frame and the processing table are welded together.

[0010] Furthermore: the notching wheel is hingedly connected to the support frame, and the bracket is welded to the processing table.

[0011] Furthermore: the spring is bolted to the bracket.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The two springs supported by the bracket push the support frame inwards through elastic force, so that the support frame drives the notching wheel to close tightly under the support of the limit rod, and marks are made on the part of the bottom edge surplus material to be bent between the two notching wheels, so that the bottom edge surplus material can be smoothly turned over 90 degrees to fit the side of the heat insulation cotton material during subsequent bending. By setting the design of notching the notching wheel pressed by the spring to notch, the bottom edge surplus material to be turned over and hemmed is pre-processed, the folding resistance is reduced, and the hemming effect is improved;

[0014] 2. The processing table supports the glue applicator to apply glue to the top surface of the bottom edge residue. When the glued bottom edge residue passes through the bending frame, the bending frame drives the bottom edge residue to fold and fit the side of the thermal insulation cotton material through an arc to achieve edge wrapping. Finally, the drying box supports the electric heating wire to release heat to dry the folded bottom edge residue, promote the solidification of the glue, and improve the reliability of the edge wrapping. Through the coordinated design of the notching device, glue applicator, bending frame, and heating wire, the thermal insulation cotton material can automatically complete stable edge wrapping during movement, thereby improving the smoothness of the device operation and saving processing time.
