A kind of graining machine heating unit
Technical field
The utility model relates to chemical industry equipment, the heating unit of the graining machine that uses in particularly a kind of leather-making technology.
Background technology
At present, what the heating unit of the graining machine that uses in leather-making technology adopted is dry combustion method formula heating tube heating system, general every heating tube power 1KW, amount to 75, i.e. 75KW, the whole heating of heating tube, by heating mantles reflection and the heating of heating tube bottom, to the product surface heating, as shown in Figure 1.But this kind heating unit is far away apart from embossing roller, and make that easily heating is uneven, thermo-efficiency is low, the different product of thickness is difficult for adjusting control, cause thin product often overheated, thick product by heating inequality, and the embossing lines is unintelligible, and production rate is slow, quality is unstable, consumption is high.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, a kind of graining machine heating unit is provided, can improve problems such as the heating unit thermal power is low, thermosteresis is big, quality is unstable, production rate is slow, the product lines is unintelligible, stable practical, save energy.
In order to achieve the above object, the technical solution adopted in the utility model is such:
A kind of graining machine heating unit comprises framework and heating tube, and described framework is a suspension bracket, and heating tube is gold-plated quartz heating-pipe, and heating unit is positioned at directly over embossing roller and the rubber roll, and the vertical distance of the bottom of heating unit and embossing roller is less than 5cm.
Described gold-plated quartz heating-pipe is grouping heating, independent control.
In the selection of heating tube, remove the heating tube of the whole heating of traditional dry combustion method formula, improve and use gold-plated quartz heating-pipe, there is the gold-plated isolation of one deck reflecting layer at the back side of gold-plated quartz heating-pipe, make it in heat-processed, heat can not distribute, by the specular reflection infrared rays, make all heatings downwards of heat, evenly to the product by heating plasticizing.
In control, remove integral body heating in the past, use grouping control instead.Traditional heating mantles heating unit, integral body is heated, and to producing thin product, surface local is heated overheated, causes thickener sometimes, but to thick product, normally surface temperature is enough, and the middle layer heating is inhomogeneous, causes the product lines of production shallow, unintelligible.The utility model utilizes the characteristic of gold-plated heating tube, divides three groups, every group three heating tubes, and every group of independent control.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
Utilize gold-plated reflected infrared heating technique, improve former graining machine heating unit, improve thermo-efficiency, increase products production speed, improve the product surface state.Heating unit adopts the short period of time rapid heating as far as possible near the embossing assembly, makes the mechanical property loss of material minimum, homogeneous heating, and the product thickness loss is little, and decorative pattern is more clear.The grouping heating, independent control at differences such as different product thickness relations, degree of heat, Heating temperature, times, has promoted heating stability, practicality greatly, reduces consumption, save energy, has improved production efficiency.

Mark among the figure: 1 is quartzy thermofin, and 2 is embossing roller, and 3 is rubber roll, and 4 are dry combustion method formula heating tube, and 5 are the heating suspension bracket, and 6 is gold-plated quartz heating-pipe, and 7 is gold-plated isolation reflecting layer, and 8 is heater strip.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Be traditional graining machine and heating unit as shown in Figure 1, adopt quartzy thermofin 1 and dry combustion method formula heating tube 4, the conventional art heating is uneven, product thickness different heating quality difference, embossing lines are unclear, and whole heating system is that whole control, energy consumption are big, generates heat by heating tube, reflect to form heat through heating mantles again, production efficiency is low, and speed is slow, general 5-6m/min.
Be graining machine heating unit synoptic diagram described in the utility model as shown in Figure 2.A kind of graining machine heating unit comprises framework and heating tube, and described framework is a suspension bracket 5, and heating tube is gold-plated quartz heating-pipe 6, and heating unit is positioned at directly over embossing roller 2 and the rubber roll 3, and the vertical distance of the bottom of heating unit and embossing roller is less than 5cm.
Described gold-plated quartz heating-pipe is grouping heating, independent control.
9 of the gold-plated quartz heating-pipes of the utility model, every power 2KW amounts to 18KW.
There is the gold-plated isolation of one deck reflecting layer 7 at the back side of gold-plated quartz heating-pipe, and in heater strip 8 heating processes, heat can not distribute, and by the specular reflection infrared rays, makes all heatings downwards of heat, to the product by heating plasticizing evenly fully.The heat abundance, stability is high, also can make the product embossing lines of production clear, controlled, adjustable according to producing thick, the thin temperature that will use of regulating of different products, and production efficiency is brought up to 8-12 m/min by original 5-6 m/min, has increased more than 25%.One group or several groups can be opened or close to gold-plated quartz heating-pipe 6 grouping heating, independent control as required, have greater flexibility.
Graining machine heating unit described in the utility model has promoted heating stability, practicality, reduces consumption, save energy, has improved production efficiency.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
