Abstract
The invention discloses an electrical-steam PVC (polyvinyl chloride) plastic board local-heating device, which comprises a tank body (1), an infrared heating pipe (3) and wires (4). The device is characterized by also comprising a pipeline (2), wherein the pipeline (2) comprises a steam inlet pipeline (21), a heating pipeline (22) and a steam outlet pipeline (23); the heating pipeline (22) is arranged at the bottom of an inner cavity of the tank body (1); one end of the heating pipeline (22) is connected with the steam inlet pipeline (21), and the other end of the heating pipeline (22) is connected with the steam outlet pipeline (23); the steam inlet pipeline (21) and the steam outlet pipeline (23) are arranged outside the tank body; holes (11) are symmetrically formed in the left and right sides of the tank body (1); the left and right ends of the infrared heating pipe (3) are arranged in the holes (11) in the left and right sides of the tank body (1), and are close to the heating pipeline (22). The device is simple in structure, low in cost, safe and reliable, and has good heating effects, and heating modes are flexible.
Description
Technical field
The present invention relates to device of plastic processing, specifically electric and gas dual-purpose PVC plastic plate area heating installation.
Background technology
When PVC sheet material is carried out to bending machining, first to need carry out crooked position heating to PVC plastic plate, then, the PVC plastic plate after heating is delivered in special-purpose bending machine again and carried out bending, the existing mode that PVC plastic plate is heated is to adopt infrared ray heating tube to heat, this mode of heating, usually there is following problem: if when heating-up temperature is too high, easily burn on the surface of PVC plastic plate, gently affects attractive in appearance, heavy scrap; When if heating-up temperature is lower, the centre of PVC plastic plate can not heat penetration, causes producing the quality problems such as shattered crack when it is carried out to bending.
Summary of the invention
Object of the present invention is just to provide a kind of simple in structure, mode of heating is flexible, heating effect is good, cost is low, safe and reliable electric and gas dual-purpose PVC plastic plate area heating installation.
For achieving the above object, electric and gas dual-purpose PVC plastic plate area heating installation of the present invention comprises casing, infrared ray heating tube and wire, also comprise pipeline, described pipeline comprises admission pipeline, water back and steam outlet pipe road, described water back is loaded on the bottom of cabinets cavity, one end of described water back connects admission pipeline, the other end connects steam outlet pipe road, the outside of casing is all located in described admission pipeline and steam outlet pipe road, left side and the right side of described casing are arranged with hole, left and right two ends of described infrared ray heating tube are loaded on respectively on the left of casing and in the hole on right side also adjacent on water back.
The present invention is owing to having adopted the pipeline configuration being comprised of admission pipeline, water back and steam outlet pipe road, vapours enters through admission pipeline the water back being loaded in casing, through steam outlet pipe road, flow out again, in this process, water back is heated by vapours, and by thermal energy transfer the base plate to casing, now, the PVC plastic plate that is close to tank floor is heated thereupon, until reach technological requirement, owing to adopting vapours to heat PVC plastic plate, temperature can be not too high, therefore can eliminate PVC plastic plate completely because of overheated phenomenon of burning; And be located on the left of casing and the hole on right side, and be both convenient to installation infrared heating tube, be conducive to again the ventilation of cabinets cavity, also can convenient operation workman observe the situation in casing; In addition, infrared ray heating tube can be used as auxiliary heating mode, to improve the efficiency of heating surface.The present invention is simple in structure, and mode of heating is flexible, and heating effect is good, and cost is low, safe and reliable.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Fig. 3 is applied in any combination schematic diagram of the present invention.
The specific embodiment
Referring to Fig. 1 to Fig. 2, electric and gas dual-purpose PVC plastic plate area heating installation of the present invention comprises casing 1, infrared ray heating tube 3 and wire 4, also comprise pipeline 2, described pipeline 2 comprises admission pipeline 21, water back 22 and steam outlet pipe road 23, described water back 22 is loaded on the bottom of casing 1 inner chamber, one end of described water back 22 connects admission pipeline 21, the other end of water back 22 connects steam outlet pipe road 23, the outside of casing is all located in described admission pipeline 21 and steam outlet pipe road 23, the left side of described casing 1 and right side are arranged with hole 11, left and right two ends of described infrared ray heating tube 3 are loaded on respectively in the hole 11 on casing 1 left side and right side and are adjacent on water back 22.
Fig. 3 is applied in any combination schematic diagram of the present invention, during work, two electric and gas dual-purpose PVC plastic plate area heating installation symmetries is positioned over to the upper-lower position that PVC plastic plate 5 needs heating position; If in the time of will heating a plurality of positions of PVC plastic plate 5 (as: U-bend is bent) simultaneously, need need heat the symmetrical electric and gas dual-purpose PVC plastic plate area heating installation of placing of upper-lower position at position in each of PVC plastic plate 5, can to a plurality of positions of PVC plastic plate 5, heat simultaneously.
