A self-contained heated shoe formwork unit for circular conveyor lines

Abstract

The invention discloses an independently heated shoe mold frame unit for a circular transportation line, which comprises a shoe mold frame body and a shoe mold installed in the shoe frame body, and also includes an independent heating mechanism, which includes at least An electric heater fixedly embedded in the bottom of the shoe mold and an independent power supply unit fixedly installed on the main body of the shoe mold frame; the independent power supply unit includes a mounting plate, a pressing mechanism fixed on the mounting plate and at least two A conductive sheet, the mounting plate is fixed on the main body of the shoe mold frame, the pressing mechanism presses the conductive sheet on the power supply track of the heating station of the circular transportation line, and the conductive sheet is electrically connected to the electric heater. The invention changes the oven heating structure of the traditional shoe-making production line, and proposes an independent heating shoe formwork unit, which has high heating efficiency, good uniformity, ideal polyurethane foaming effect, high utilization rate of heat energy, environmental protection and energy saving , to meet the heating requirements of the ring shoe production line.

Description

technical field [0001] The invention relates to the field of shoe brake production, in particular to an independently heated shoe formwork unit used in a circular transport line. Background technique [0002] In the streamlined production of shoemaking, a large oven is generally installed on the production line. After adding polyurethane to the shoe mold, the mold is closed and enters the oven for foaming and curing. The structure of the traditional oven is relatively simple, including an outer shell made of thermal insulation material, and a plurality of electric heating pipes are installed inside the outer shell for heating. The heat loss of this oven structure is high. As long as the shoemaking operation is carried out (whether it is to make a pair of shoes or the entire production line is working at full load), the entire oven needs to be opened, and the heat energy utilization rate is extremely low. In addition, after the shoe mold frame enters the oven, the heat energ...

Problems solved by technology

The heat loss of this oven structure is high. As long as the shoemaking operation is carried out (whether it is to make a pair of shoes or the entire production line is working at full load), the entire oven needs to be opened, and the heat utilization rate is extremely low.

In addition, after the shoe mold frame enters the oven, the heat energy will heat up the polyurethane to foam and solidify through heat transfer, and a large part of the heat energy will be absorbed by the entire shoe mold frame and shoe mold, which not only prolongs the polyurethane foam curing time, At the same time, it will adversely affect the foaming and curing effect
