Improved vacuum-sulfurizing, bottom-sticking, freezing-moulding technique for processing boots and device thereof

Abstract

The invention relates to a processing technical improvement for vacuum sulphurating sole laying freezing sizing shoes and a device thereof. A rotating shaft which passes through a reduction gear box is inserted into an upper rotating disc and a lower rotating disc for fixing, and a plurality of sulphurating boxes for placing shoes to be shaped or shoe placing shelves or freezing boxes are fixed between the upper rotating disc and the lower rotating disc so as to ensure that the rotating shaft drives the upper rotating disc and the lower rotating disc to intermittently rotate for a preset angle, and then stop. At the same time, the front side of the vacuum sulphurating boxes positioned at a working position is provided with a heating sealing cover, or the front side of the freezing boxes at the working position is provided with a sealing box, wherein the heating sealing cover and the sealing box are both transmitted by a transmission shaft of a cylinder to control the sealing and vacuum-pumping with the vacuum sulphurating boxes or the freezing boxes. Then, the actions of sulphurating or frozen shaping and opening are carried out, and hot wind is sent into the vacuum sulphurating boxes by an air blowing-in blower through the heating sealing cover, and exhausted by an air draft blower; or in the vacuum freezing boxes, the sealing box seals the vacuum freezing boxes, and after being pumped with the vacuum, the shoes are sent into low temperature to be rapidly frozen so as to ensure that the shoes are shaped.

Description

technical field [0001] The present invention relates to an improvement of the processing technology of vacuum vulcanized bottom-attached frozen shaped shoes and its device, in particular to a process of making shoes by rotating shoe racks and vacuum boxes, which can reduce the size of the production line and reduce the space occupied , and can be used for the manufacture of large and small quantities of shoes and boots, and achieve the technical field of the mobility of the shoemaking process. Background technique [0002] According to the general shoe production line such as figure 1 , figure 2 As shown, it is composed of a vulcanization production line A, a bottom sticking production line B, and a freezing and setting production line C; the vulcanization production line A is in the vulcanization production line A after the sole is coated with glue Dry the glue and activate the glue at the same time, then put the sole into the bottom sticking production line B to manuall...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing shoe-making production line has to stretch several tens of meters, which takes up a lot of space, and it is more economical to manufacture a large number of shoes. If a small number of shoes are manufactured, the production line will inevitably increase the cost and is not economical. benefit to speak of;

[0005] 2. The existing shoe-making production line does not meet the requirements of energy conservation due to its large size and considerable electricity consumption;

[0006] 3. The vulcanization production line of the existing shoe-making production line, because the shoes and boots are conveyed by the conveyor belt, the vulcanization is non-closed, so the odor pollution of the viscose after vulcanization is unavoidable, and it is easy to endanger human health;

[0007] 4. The existing freezing and setting machine enters the freezer due to the conveyor belt, and the cold air is easy to lose, resulting in waste of energy and failing to achieve energy saving effect
