Details and the operation principle of embodiment of the present utility model and embodiment are described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is four preheating great circle rollers, and before and after point, the sheet material of two groups is wound around schematic diagram.
Detailed description of the invention
See accompanying drawing, the preheatting cabinet of thermoforming machine for plastic products in present embodiment, comprise cabinet 0 and cabinet door, described cabinet 0 and cabinet door (not shown, hinge 18 is wherein installed install for the cabinet door of insulation) form the space, cabinet room closed, this space, cabinet room is communicated with discharging opening with charging aperture, charging aperture and discharging opening are arranged on cabinet, charging aperture and discharge outlet respectively correspondence arrange feed roller 7 and discharge roller 12, space, enclosed cabinet room is safer, thermal loss is few, and closed not referring to seals completely.Cabinet is also provided with heating watt cover 14, discharge outlet sets out mouthful supporting plate 15.
Be provided with rotating preheating great circle roller 10 and draw-gear 20 in described cabinet 0, support 9 can be set in cabinet and arrange for preheating great circle roller and draw-gear.Described draw-gear 20 comprises carry-over pinch rolls 11, described carry-over pinch rolls 11 are by power source transmission, carry out transmission traction roller as by driven by motor reductor, carry-over pinch rolls 11 can adopt rubber rollers or silica gel roller to coordinate in draw-gear again and arrange steel rider 17 to draw feeding sheets advance.Described preheating great circle roller 10 is driven member, and the outer surface of the cylinder of described preheating great circle roller 10 adopts sandblasting and the process of spraying teflon coatings, and cylinder is connected with heater.Sheet material passes through charging aperture, after feed roller 7 transition, winding (can also arrange some transition rollers 8) on preheating great circle roller 10 when winding, and sheet material carries out traction by the carry-over pinch rolls (as rubber rollers, silica gel roller etc.) of draw-gear to be carried, and then sheet material by discharge roller 12 transition from discharging opening out.When work, sheet material is drawn by draw-gear, and sheet material drives driven member preheating great circle roller to rotate, and sheet material and preheating great circle roller outer surface keep being synchronized with the movement, and sheet material and preheating great circle roller directly contact and carry out heat trnasfer and carry out preheating.The outer surface of preheating great circle roller 10 is through process (adopting sandblasting and the process of spraying teflon coatings), and the contact of therefore preheating great circle roller and sheet material is even, be heated evenly, keep being close to and sheet material can not be bonded on preheating great circle roller.If not surface treatment, preheating great circle roller contacts uneven with smooth sheet material, affects the effect of sheet material, even destroys the fineness of sheet surface.
The cylinder of preheating great circle roller 10 can adopt aluminum or aluminum alloy materials, its thermal conductivity is better, and can guarantee that sheet material and preheating great circle roller outer surface keep being synchronized with the movement, there will not be skidding, there will not be the phenomenon of sheet material stop motion and preheating great circle roller continuation motion.Therefore would not destroy the mirror effect of sheet material, not affect the glossiness of sheet material, more there will not be the phenomenon of stretching.If cylinder adopts its thermal conductivity of iron material and being synchronized with the movement property of maintenance to be all not so good as aluminum or aluminum alloy materials, easily there is skidding, occur relative motion, destroy the mirror effect of sheet material.
The left and right sides of described preheating great circle roller 10 is respectively rotating disk, preheating great circle roller 10 is arranged in rotating shaft 21 by left and right rotating disk, (heater can be heating wire or heating tube or heating plate preheating great circle roller 10 inwall evenly to be arranged heater, heating tube can adopt electrothermal tube), rotating disk is provided with the opening that supplying/heating system is installed.Therefore heater is built-in, and direct and large cylinder contact internal walls, and heat transfer effect is good, speed is fast, and power consumption is few.We also can adopt and arrange interlayer on cylinder, and inside interlayer, note establishes oil, arranges heating plate inside fluid, and make oil heat by heating plate, then heat conduction is on cylinder, but this mode bad, an inadequate health, two oily electrical environments are dangerous.
Two setting up and down of described preheating great circle roller 10, the heating-up temperature of described heater can regulate setting.Different technological temperature demands can be met.Described preheating great circle roller can also arrange four, and setting up and down two is one group, and front and back are set to two groups by four preheating great circle rollers, can meet the path and time that increase preheating.Even can the temperature of up and down preheating great circle roller arrange different, carry out satisfied two kinds of different temperature requirements.
Be provided with the air outlet 13 be communicated with hot air source in described cabinet 0, the air-out path of air outlet is between preheating great circle roller and discharging opening.Increase the pre-heat effect of preheating cabinet, make to form preheating environment in whole cabinet space.
When in present embodiment, the preheatting cabinet of thermoforming machine for plastic products works, by sheet material winding on the carry-over pinch rolls, discharge roller of feed roller, preheating great circle roller, draw-gear, heater work preheating great circle roller is in operating temperature, then draw-gear work, sheet material starts to move from charging aperture toward discharging opening, sheet material and preheating great circle roller keep being synchronized with the movement, and during preheating, air outlet can also blow out hot blast.Adopt the volume of the preheating swift preheatting cabinet comparatively speaking of drum-type relatively little; Adopt its preheating method of preheating swift of being connected with heater for directly to carry out heat trnasfer, heat transfer effect is good, and sheet material preheating is evenly, quick and energy-conservation; The outer surface of preheating great circle roller is through process, and the contact of therefore preheating great circle roller and sheet material is even, be close to and sheet material can not be bonded on preheating great circle roller; Cylinder adopts aluminum or its good heat conductivity of aluminum alloy materials, good, the driven performance of heat trnasfer is good and driven motions stable, can the fine motion synchronicity that must keep preheating great circle roller and sheet material, avoid the skidding occurring preheating great circle roller and sheet material.In present embodiment the preheatting cabinet of thermoforming machine for plastic products discharging opening by directly and system mould product heating part (as baking oven) and carry out online, sheet material enters into system again and moulds product heating part (as baking oven) and heat after the preheating of the preheatting cabinet of thermoforming machine for plastic products in present embodiment, shorten the sheet material heat time, and make the heating effect of sheet material better (evenly and not destroying sheet quality), the system of improve moulds product productivity ratio.Sheet material is first by after the preheatting cabinet heating in present embodiment, and system is moulded product heating part (as baking oven) and designed corresponding shortening.
