Abstract
The utility model discloses a heater for a screen printing plate. The heater comprises a support and a heating bin arranged in the support. A temperature sensor, a conveyor belt for the screen printing plate, and a radiant heater under the conveyor belt for the screen printing plate are arranged in the heating bin. The radiant heater comprises a plurality of light wave tubes uniformly distributed, and a protecting cover arranged above all the light wave tubes, wherein light waves can penetrate through the protecting cover. The inner wall of the heating bin is provided with a reflecting layer used for reflecting the light waves. The temperature sensor and all the light wave tubes are respectively connected to a temperature controller. According to the heater for the screen printing plate, assistance of heated air circulation is not needed, pollution in the drying process of heated air circulation is avoided, the drying efficiency can be improved, energy sources can be saved, and the quality of the screen printing plate is improved; when the heater for the screen printing plate is used for forming a drying production line, the cycle of the drying production line of the screen printing plate can be greatly shortened, and the occupied area of equipment is reduced.
Description
Technical field
The utility model relates to half tone heater.
Background technology
Existing half tone drier, the heating system being formed by motor, fan blade and electric heating bar.Existing drier is by electric heating bar (being generally 2) sustained release heat, and make the air circulation in drier by the rotation of driven by motor fan blade, air adds thermosetting hot-air through fire-bar, and hot-air circulates in drier, thereby reaches dry effect.
But because air is constantly recycled, thereby cause the dust falls such as airborne 1 μ, 3 μ, can adhere on half tone, cause client's product to have flaw, even cannot use, and the energy loss of heated-air drying half tone is larger.
Utility model content
The purpose of this utility model is to provide a kind of half tone heater, do not need hot air circulation auxiliary, overcome the pollution in heat-wind circulate drying process, and can improve drying efficiency, save the energy, improve the quality of half tone, use this half tone Heater group to become to dry to produce line, can greatly shorten half tone and dry the length of producing line, reduce the floor space of equipment.
For achieving the above object, the technical solution of the utility model is a kind of half tone heater of design, comprises support and is located at the heating cabinet on support; In described heating cabinet, be provided with temperature sensor, half tone conveyer belt, and be positioned at the pharoid under half tone conveyer belt; Described pharoid comprises some uniform optical wave tubes, and the protective cover that is positioned at each optical wave tube top and can be penetrated by light wave; Described heating cabinet inwall is provided with the reflecting layer for reflecting light; Described temperature sensor, each optical wave tube are connected to respectively temperature controller.
Preferably, described each optical wave tube is parallel to half tone conveyer belt extension (transmission) direction.
Preferably, described each optical wave tube extends (transmission) direction perpendicular to half tone conveyer belt.
The light wave giving off by pharoid, directly penetrates the photosensitive layer of half tone, makes the hydrone strenuous exercise of photosensitive layer, thereby evaporation reaches dry effect.
Control by temperature controller to each optical wave tube, can accurately control heating-up temperature, improves the efficiency of heating surface.
Use the mode of radiation heating half tone, do not need hot air circulation auxiliary, it is static that the air in heating cabinet keeps, and overcome the pollution in heat-wind circulate drying process.
By pharoid, to the direct radiation heating of half tone, the resin bed that makes half tone is dry by inner and table, has improved the quality of half tone.
To the direct radiation heating of half tone, utilize the simple and direct thermaltransmission mode of light radiation by pharoid, and from inside to outside dry, improve drying efficiency, save the energy, through contrast test, can save energy more than 60%.
The raising of the unit drying efficiency of half tone heater, the length that can shorten the oven dry that is made up of half tone heater and produce line, has greatly reduced the floor space of equipment, and can improve the production efficiency of whole supporting product line.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
The concrete technical scheme of implementing of the utility model is:
As shown in Figure 1, a kind of half tone heater, comprises support 1 and is located at the heating cabinet 2 on support 1; In described heating cabinet 2, be provided with temperature sensor 3, half tone conveyer belt 4, and be positioned at the pharoid 5 under half tone conveyer belt 4; Described pharoid 5 comprises some uniform optical wave tubes 51, and the protective cover 52 that is positioned at each optical wave tube 51 tops and can be penetrated by light wave; Described heating cabinet 2 inwalls are provided with the reflecting layer (not shown on figure) for reflecting light; Described temperature sensor 3, each optical wave tube 51 are connected to respectively temperature controller (not shown on figure).
Described each optical wave tube 51 is parallel or perpendicular to half tone conveyer belt 4 and extends (transmission) direction.
The light wave giving off by pharoid 5, directly penetrates the photosensitive layer of half tone 6, makes the hydrone strenuous exercise of photosensitive layer, thereby evaporation reaches dry effect.
Control by temperature controller to each optical wave tube 51, can accurately control heating-up temperature, improves the efficiency of heating surface.
Use the mode of radiation heating half tone, do not need hot air circulation auxiliary, it is static that the air in heating cabinet 2 keeps, and overcome the pollution in heat-wind circulate drying process.
By pharoid 5, to the direct radiation heating of half tone 6, the resin bed that makes half tone 6 is dry by inner and table, has improved the quality of half tone.
To the direct radiation heating of half tone 6, utilize the simple and direct thermaltransmission mode of light radiation by pharoid 5, and from inside to outside dry, improve drying efficiency, save the energy, through contrast test, can save energy more than 60%.
The raising of the unit drying efficiency of half tone heater, the length that can shorten the oven dry that is made up of half tone heater and produce line, has greatly reduced the floor space of equipment, and can improve the production efficiency of whole supporting product line.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
