5. Transmission parts:
Transmission part: The feed area is equipped with auxiliary roller 3, the material area with 3, roller surface covered with silicone, which can effectively prevent the product when the scratch product, roller speed and belt speed synchronous movement, conveyor belt carbon steel Double-pitch chain drive, the chain between the use of 4-point double-pitch chain, the middle of the chain with 1.5mm thick stainless steel bending plate connection, spacing of 10 cm for each board, and then flattened in the stainless steel plate imported black iron Teflon mesh belt, Teflon mesh belt with two bags on the edge of the uniform red holes, with screws to fix the chain plate, in the tunnel furnace upper and lower chain drag rail track, both before and after the active and passive large Wheel, so that is not conducive to scratches the belt with the network side.
UV portion
(A) specifications and configuration requirements:
1. Light source: 3 sets of imported 7KW UV light source. With the Japanese original halogen lamp, before and after evenly distributed in the furnace (with step-up transformer, reflector, lamp, capacitor), the installation of UV mirror reflector, greatly improving the utilization of ultraviolet light up to 35%. Each group of UV lamps can be individually controlled, each tube can be individually adjusted semi-light / all-optical, with adjustable angle adjustment mechanism, can be about, up and down height adjustment (adjustable angle of 90 degrees) Tube angle adjustment device, the top lid are equipped with adjustable UV lamp up and down the height of the handle handle for different specifications. Multi-faceted products UV light solid. (Total length 1100mm, the effective distance 1050mm, wavelength 365nm) equipped with automatic timer, the lamp can be monitored at any time, to facilitate the replacement lamp. Each lamp is equipped with imported quartz insulated glass, effectively prevent its infrared heat radiation to the product, so as to avoid the product by the temperature is too high and deformation. (UV control electrical equipment installed in the silk screen room control box)

With UV lamp ammeter, lighting timer, lighting completion indicator. Aluminum alloy forming mirror reflector. To reduce the operating temperature and reduce lamp loss. Large flow of exhaust design, can quickly discharge the heat and exhaust gas in the work area.
Stepless dimming system of the lamp in the early stage, 3 8kw in the later stage, which can be applied to more kinds of inks with different effects
The longer the Heating Leveling Machine, the better,
The cooling zone is optional. The reason why it is recommended to increase the zone is that the product stacks are slightly stuck without cooling, and there will be abnormal noises when they are peeled off and separated.
