Shoe upper and shoe tree vertical circulation two-in-one dryer

Abstract

A shoe upper and shoe tree vertical circulation two-in-one dryer comprises a shared drying oven, a conveying chain, transmission wheels, a shoe tree hanging bracket, a speed regulation and reducing machine, an air source heat pump, an electric heating system, a table board conveying belt, an electric control cabinet and an operation table. The shared drying oven is fixed on a machine frame, and the conveying chain enters the shared drying oven from an inlet of the drying oven through the transmission wheels, operates towards one end and returns upwards at 360 degrees to exist from an outlet of the drying oven to form a circulation loop. The shoe tree hanging bracket is hung on the conveying chain, the group of transmission wheels is connected with the speed regulation and reducing machine, the air source heat pump is arranged at one end of the shared drying oven, and a convection fan is arranged at the other end of the drying oven. A separation board is arranged in the shared drying oven to divide the shared drying oven into a production line drying zone and a shoe upper heating zone, and therefore the two-in-one dryer has the function of drying two products simultaneously.

Description

Technical field [0001] The invention relates to drying equipment for shoe uppers and lasts in the shoemaking industry, in particular to a vertical circulation two-in-one dryer for shoe uppers and lasts. Background technique [0002] At present, in the shoemaking industry, the known processes of humidifying and softening the upper and heating and drying the shoe last generally adopt an electric heating tube oven and a coal-fired oven with a cylindrical structure, both of which are indispensable. The installed power of the electric heating tube oven is generally about 10-20KW / H, and the energy consumption of the coal-fired oven is about 100 yuan a day. Both of them operate separately at the same time, and the excess waste heat cannot be used for each other, and the operating cost remains high. The disadvantages of coal-fired ovens are not only slow temperature rise when lighting a fire and temperature changes when adding coal, but also the main disadvantages of polluting the e...

AI Technical Summary

Problems solved by technology

The installed power of the electric heating tube oven is generally about 10-20KW / H, and the energy consumption of the coal-fired oven is also about 100 yuan a day. Both of them operate separately at the same time, and the excess waste heat cannot be used for each other, and the operating cost remains high.

The disadvantages of coal-fired ovens are not only slow temperature rise when lighting a fire and temperature changes when adding coal, but also the main disadvantages of polluting the environment, low thermal efficiency, and large floor space.

[0003] Half of the circulation line of the "A Two-in-one Dryer for Shoe Upper and Last" (201120302703.1), which I applied for earlier, runs outside the oven, which results in low efficiency and partial heat loss. If the exposed part is sealed into The drying tunnel will increase the cost of materials and heat source, and there are design defects in this scheme
