Abstract
A hot-air vulcanising drying tunnel consists of a front vulcanising drying tunnel and a rear vulcanising drying tunnel, wherein, electric heating elements are arranged inside the front vulcanising drying tunnel and the rear vulcanising drying tunnel, a transmission belt supported by a support shaft is arranged under the electric heating element in the rear drying tunnel. The utility model has the advantages that: 1. The high working temperature of the front vulcanising drying tunnel makes a product surface quickly shaped and semi-vulcanised, thereby maintaining the good silicon rubber performance of the product and improving the production efficiency, 2. quickly shaping can be all achieved to glue strips of various complex shapes, thereby maintaining the correct designing shape and size, avoiding the defects of adhesion, press mark and deformation, and improving the surface quality of vulcanising product, 3. tidiness, sanitation and non-pollution are provided by adopting the packing of stainless steel, 4. the whole hot-air vulcanising drying tunnel has short total length and small occupied area.
Description
Technical field
The utility model belongs to vulcanizing plant, particularly a kind of novel hot-air vulcanization drying tunnel.
Background technology
Domestic production silicon rubber extruded product all adopts normal pressure hot-air vulcanization mode.Traditional hot-air vulcanization drying tunnel is an one-piece construction, and length overall is about about 6-8 rice, adopts the tubular heater electrically heated, and working temperature is provided with travelling belt in the drying tunnel below 300 degree, be used for carrying the silicon rubber extruded product.Traditional hot-air vulcanization drying tunnel, because working temperature is not high, vulcanization rate is slow, thereby whole drying tunnel length is very long, the speed of travelling belt can not be very fast, otherwise will cause the inadequate defective of sulfuration.The production efficiency of whole sulfuration drying tunnel is lower, and generally per hour throughput is up to 1-2Kg.Because the plasticity-of silicon rubber own is big, after extruded product enters drying tunnel, because envrionment temperature is not very high, goods are very soft, very easily form obvious marks at product surface and travelling belt contact part, influence shape of products and quality, especially vulcanize diameter is big, tube wall is thicker sebific duct or thin-walled tube, not only have impression, because the deadweight of material itself also can cause product deformation, can not guarantee correct shape, can't finish especially as for the special-shaped adhesive tape of section form complexity.
Technology contents
The purpose of this utility model provides a kind of novel hot-air vulcanization drying tunnel, satisfies the sulfuration needs of silastic product fully, has realized efficient high-speed vulcanization, has eliminated the deficiency and the defective of traditional hot air curing mode fully, has very high production efficiency.
The technical solution of the utility model is: novel hot-air vulcanization drying tunnel, form by the sulfuration drying tunnel, it is characterized in that: the sulfuration drying tunnel is made up of preceding sulfuration drying tunnel and postcure drying tunnel, preceding sulfuration drying tunnel and postcure drying tunnel are built-in with electrical heating element, and the electrical heating element below is provided with the travelling belt by the back shaft support in the postcure drying tunnel.
Sulfuration drying tunnel and postcure drying tunnel are coated by stainless steel plate before said.
The utlity model has following advantage: 1, preceding sulfuration drying tunnel working temperature height, make product surface fast shaping and semicure, the good silicon rubber performance that has kept goods, improved production efficiency, 2, for the adhesive tape of different shape complexity, realize fast shaping, keep correct design shape and size, avoided the defective of adhesion, impression, distortion, improved the surface quality of vulcanized article, 3, adopt stainless steel to coat, clean and tidy health, pollution-free, 4, whole hot-air vulcanization drying tunnel total length is shorter, floor space is little.
Description of drawings
Accompanying drawing 1 is the utility model structural profile synoptic diagram.
Accompanying drawing 2 is preceding sulfuration drying tunnel and postcure drying tunnel structural profile synoptic diagram.
Among the figure: the 1st, silicone tube, the 2nd, preceding sulfuration drying tunnel, the 3rd, electrical heating element, the 4th, postcure drying tunnel, the 5th, travelling belt, the 6th, travelling belt back shaft, the 7th, stainless steel plate, the 8th, conveyor drive arrangement.
Specific embodiments
As shown in Figure 1, 2, novel hot-air vulcanization drying tunnel, the length that is coated by stainless steel plate 7 is that the preceding sulfuration drying tunnel 2 of 500mm and postcure drying tunnel 4 that length is 4000mm are formed, preceding sulfuration drying tunnel 2 and postcure drying tunnel 4 are built-in with special electrical heating element 3, electrical heating element 3 belows in the postcure drying tunnel 4 are provided with the travelling belt 5 that is supported by back shaft 6, silicone tube 1 places on the travelling belt, is driven by conveyor drive arrangement 8 and transmits.
Using method: the silastic product of extruding aborning is unsettled enter before sulfuration drying tunnel 2, reach as high as the high temperature of the special electrical heating element 3 of 900 degree in working temperature, under the radiation interaction, product surface fast shaping and semicure, enter postcure drying tunnel 4 by travelling belt 5, reach as high as the high temperature of the special electrical heating element 3 of 700 degree in working temperature, vulcanize fully under the radiation interaction, because the silicon rubber extruded product is very fast by whole drying tunnel, can finish sulfuration fast, and the actual temperature of goods does not reach critical technological temperature yet, the good silicon rubber performance of goods and correct design shape and size have been kept, avoided adhesion, impression, the defective of distortion has improved the surface quality of vulcanized article.
Claims (2)
1, novel hot-air vulcanization drying tunnel, form by the sulfuration drying tunnel, it is characterized in that: the sulfuration drying tunnel is made up of preceding sulfuration drying tunnel and postcure drying tunnel, and preceding sulfuration drying tunnel and postcure drying tunnel are built-in with electrical heating element, and the electrical heating element below is provided with the travelling belt that is supported by back shaft in the postcure drying tunnel.
2, novel hot-air vulcanization drying tunnel according to claim 1 is characterized in that: sulfuration drying tunnel and postcure drying tunnel are coated by stainless steel plate before said.
