Description
Technical Field
The invention relates to a processing technology of a fire-fighting air duct, in particular to a side edge sewing device of the fire-fighting air duct.
Background
When a fire-fighting smoke exhaust air duct (the fire-fighting air duct for short) is processed, two symmetrical bending plates are generally selected to be buckled, and then the edge of the bending plate is curled, so that the two bending plates can be sewn through the curled edge. Present fire control dryer sew up and can only rely on the manual work to beat, and each 1.5 meters fire control dryer probably needs the manual work to beat more than 30 minutes and sews up, and the cost is more than 35 yuan, because angle, the dynamics problem of manual work beating in addition, can make the unsmooth of department of sewing up, seriously influences and sews up quality and aesthetic property, and efficiency is still relatively low simultaneously.
The inventor finds that the main reason for manually beating the two half-bending plates is that the inner sides of the two half-bending plates are not supported after the two half-bending plates are assembled, if a curling machine is directly adopted for curling, the bending plates can be locally deformed, the processing quality is seriously influenced, and the qualified rate is extremely low. And the inside confined state that is of fire control exhaust air duct after two halves bent plate are assembled, consequently hardly carry out effectual support in its inside, especially under the longer prerequisite of fire control dryer itself, stretch into the fire control dryer through external device and support and just seem very difficult, and also consider the deformation problem of processing back fire control dryer, this if directly stretch into its inside and support, then the device that leads to the support after the fire control dryer deformation probably takes out hardly, especially wholly supports or the mode that half at least supported on fire control dryer length direction. And even if the interior of the wind-resistant cylinder can be supported, the installation of the bending plate, the hemming and sewing and the removal of the supporting device cannot leave the manual work, and the cost is increased due to the fact that the bending plate, the hemming and the sewing are reversely overturned.
To this, the inventor has designed a fire control dryer side suturing device, and its supporting mechanism realizes the inside support of a fire control dryer through magnetism fixed mode of inhaling suspension, and the fire control dryer can move in length direction and carry out continuous turn-up and sew up processing to improve production efficiency greatly, and guarantee the quality of turn-up seam, in order to improve the product percent of pass.
