Description

Technical Field

[0001] The utility model relates to the field of drying equipment for enameling machines, in particular to a drying device for enameling machines. Background Art

[0002] This machine gradually coats and cures insulating varnish on the surface of enameled wire. It is a crucial piece of equipment in the magnet wire industry, coating the processed copper (or aluminum) wire with a uniform layer of insulating polyvinyl varnish. The enamel used in enameled wire production contains a large amount of diluents and organic solvents, primarily benzene, xylene, and cresol. These evaporate during the curing process, causing environmental pollution and wasting energy. With the increasing number of enameled wire manufacturers, the energy-saving and environmentally friendly nature of enameling machines has become a critical issue.

[0003] For example, patent announcement number CN203826139U discloses a drying device for an enameling machine, which solves the defect in the prior art that when the enameled wire passes through an annealing furnace at high speed for deheating, the water is brought into the enameling oven due to the high speed, affecting the quality of the enameled wire. The drying device for an enameling machine of the utility model is installed on the enameling machine, and includes a fan, an air duct, an electric heating element, a hot air duct and a guide roller for conveying the enameled wire; the fan is connected to the electric heating element through an air duct; the electric heating element is connected to the hot air duct; a plurality of evenly arranged wire holes are provided on the hot air duct; and the guide roller is fixed on the enameling machine. The utility model has a simple structure and is easy to use. It first dries the water brought out by the enameled wire and then feeds the enameled wire into the oven of the enameling machine, thereby avoiding water from being brought into the enameling oven and ensuring the quality of the enameled wire.

[0004] The above patent still has some problems when in use. The enameled wire is directly exposed to the outside during the drying process, so that the harmful gas will be directly discharged after the paint film is dried and evaporated, causing the surrounding environment and the physical environment of the workers to deteriorate. Therefore, an enameling machine drying device is now needed. Utility Model Content

[0005] The purpose of the utility model is to provide an enameling machine drying device, which covers the top of the drying box by setting a heating box. While the wind box and the heating box are working to dry the enameled wire, the exhaust gas is passed into the interior of the activated carbon plate to complete the filtration until the exhaust gas is discharged after the filtration is completed, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drying device for an enameling machine, comprising a base plate, two groups of placement boxes are symmetrically installed on the left and right sides of the upper surface of the base plate, a drying box is installed in the middle of the upper surface of the base plate, a limiting groove is provided on the top of the drying box, a heating box is sealed and installed inside the limiting groove, a wind box is installed on the upper part of the heating box, a bottom slot is opened through the lower part of the drying box, a movable plug-in plate is installed inside the bottom slot, an activated carbon plate is installed inside the movable plug-in plate, and an air exchange port is opened inside the drying box which is connected to the bottom slot.

[0008] Preferably, two groups of arc-shaped positioning support plates are symmetrically installed inside the two groups of placement boxes, and a motor is provided on the front side of the placement box on the right side of the upper surface of the bottom plate, and the output end of the motor extends into the interior of the placement box.

[0009] Preferably, an exhaust port is provided in the interior of the limiting groove and is connected to the interior of the drying box. A clamping plate is provided at the lower portion of the heating box, and the outer surface of the clamping plate is plugged and installed in contact with the inner wall of the exhaust port.

[0010] Preferably, the drying box has inlets and outlets at the corresponding window positions on the left and right sides, two groups of rotating plates are rotatably installed inside each group of the inlets and outlets, and a second limiting wheel is rotatably installed inside each group of the rotating plates.

[0011] Preferably, a mounting plate is mounted inside the drying box at the air exchange port, a plurality of groups of travel rollers are provided on the upper portion of the mounting plate, and a plurality of groups of exhaust ports are opened through the upper and lower portions of the mounting plate.

[0012] Preferably, an air inlet is opened through the upper portion of the movable plug plate at the position corresponding to the air exchange port, an internal limit frame is movably installed inside the movable plug plate, the activated carbon plate is inserted into the internal limit frame, a honeycomb air filter plate is snap-fitted inside the air inlet, and two sets of exhaust nets are snap-fitted on the front and rear sides of the movable plug plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The enameled wire reel is placed by two sets of placement boxes installed on the left and right sides of the upper part of the bottom plate, so that the enameled wire can pass through the drying box stably for drying. A motor is set outside the placement box on the right side of the upper part of the bottom plate to reel the enameled wire. Two sets of first limit wheels slidably installed outside the placement box adapt to the movement of the enameled wire when the enameled wire reel is fed. Several sets of travel rollers arranged inside the drying box can improve the movement path of the enameled wire inside the drying box, so that the paint on the outside of the enameled wire can be dried more efficiently. In addition, the heating box and the bellows on the upper side of the drying box seal the drying box to prevent harmful gases from being discharged during the drying process of the enameled wire.

[0015] 2. The activated carbon plate is limited by a movable plug-in plate inserted into the bottom plate. After the bellows work to send the hot air inside the heating box into the drying box, the exhaust gas is passed into the activated carbon plate through the exhaust port opened inside the installation plate for filtration. At the same time, the exhaust gas needs to pass through the honeycomb air filter plate before entering the activated carbon plate. The coordinated use of the honeycomb air filter plate and the activated carbon plate further improves the filtration of the exhaust gas, and the exhaust gas is discharged through the exhaust net to protect the surrounding environment.
