Abstract
The utility model relates to a hot-melt adhesive gun with temperature control switch, which is applied for the bonding of industrial, furniture and decoration objects. A sealing ceramic heating unit is arranged in the internal hole of the openings of the two ends in the same direction under the heating shell inside the gun. The ceramic heating unit is provided with one ceramic external pipe with opening at one end. The ceramic external pipe includes a ceramic internal pipe, whose external surface winded with electric heating wire. The opening end of the ceramic external pipe is arranged with ceramic powder sealing body. Moreover, one sealing temperature control switch device close to the heating shell is arranged at the opening in front of the internal hole under the heating shell. The ceramic coating is arranged with a temperature control switch. A ceramic powder sealing body is arranged at the opening of the ceramic coating. The electric heating wire inside the ceramic external pipe introduces two lead wires, of which one is connected to the zero line contact of the terminal block and the other is connected to the output contact of the temperature control switch. The input contact lead wire of the temperature control switch is connected to the live wire contact of the terminal block.
Description
Technical field
The utility model relates to the PUR instrument, specifically is applied to bonding thermosol gelgun between building decoration engineering, electronic apparatus, toy, furniture manufacturing object.
Background technology
Bonding between the object in fields such as melting glue gun is widely used in building, fitting-out work, electronic apparatus, toy, furniture manufacturing.The heating structure of existing melting glue gun is to clip the PTC ceramic heating element by two sheet metals, they is wrapped as insulating materials with polyimide film again, and the separation heater element contacting with metal heating shell.The PTC ceramic heating element is made by a ptc characteristics material, utilizes its ptc characteristics to carry out temperature control and constant temperature.But, because polyimides is a kind of plastics of poor thermal conductivity, is unfavorable for the heat transmission, thereby influences the thermal efficiency, in the temperature long-term work more than 200 ℃, accelerated ageing easily, embrittlement is rotten, reduces insulativity, makes the electric property variation.Use Kapton wrapping heater element, poor sealing performance, and the operating temperature of PTC ceramic heating element can not be selected too highly, thus influence heating property and melten gel performance.Therefore, this PTC ceramic heating element with the Kapton wrapping, indexs such as its safety in utilization, reliability, life-span are relatively poor, add the various factors that assembling connects, and cause electric property poor, and the scope of application is restricted.
Summary of the invention
The purpose of this utility model provides a kind of thermosol gelgun that temperature detect switch (TDS) is arranged, and it has the safety condition of hot operation, and temperature control is accurate, the good insulation performance condition is arranged and be not subjected to the influence of temperature, humidity and working time length, long service life, safe and reliable, practical.
Technical solution of the present utility model is the rifle body at existing thermosol gelgun, nozzle, send the glue assembly, terminal plate, the heating shell, on the basis of tail sleeve pipe, the utility model particularly is provided with sealed ceramic heating element in the same way the endoporus of two end openings below rifle body internal heat generation shell, ceramic heating element has the ceramic outer tube of one one end opening, in the pottery outer tube ceramic inner pipe is arranged, the ceramic inner pipe outer surface is wound with Electrothermic wire, the seal that the ceramic powder slurry is arranged at ceramic outer tube opening end, the temperature switch device of being close to mutually with the heating shell that also is provided with a sealing at the endoporus front end open-mouth of heating below the shell, temperature switch device has one one ceramic coat that end is uncovered, be provided with temperature detect switch (TDS) in the ceramic coat, the seal that ceramic size is arranged at the ceramic coat opening end, Electrothermic wire is drawn two lead-in wires in the pottery outer tube, article one, lead-in wire is connected with zero-power line contact on the terminal plate, another lead-in wire is connected with the temperature detect switch (TDS) output contact, and temperature detect switch (TDS) input contact lead and terminal plate power firestreak contact join
More than temperature detect switch (TDS) described in the utility model be the temperature switch or the bimetal leaf temperature switch of memorial alloy type.
Be full of the seal of ceramic powder slurry between temperature switch of the present utility model and the ceramic coat.
More than be full of the seal of ceramic powder slurry between ceramic outer tube of the present utility model and the ceramic inner pipe.
Temperature detect switch (TDS) described in the utility model is the temperature switch of memorial alloy type, outer casing electrification, have isolate the operation precision height, thermal response is fast, characteristics such as inflow-rate of water turbine is big, stable performance.Temperature detect switch (TDS) mainly is to be serially connected with in the circuit of electrical appliance to use, and to contact electrical heating as far as possible and partly can play a role, because outer casing electrification when temperature detect switch (TDS) uses is isolated so in use need load onto ceramic coat, the separation temperature switch contacts with heating metal part.In the thermosol gelgun course of work, by to heater element heating,, the temperature of the heating shell that to be heater element to calandria reach heat reaches temperature detect switch (TDS) along with rising, reach the temperature of temperature detect switch (TDS) control, temperature detect switch (TDS) disconnects circuit, reaches the purpose of temperature control.The utility model utilizes ceramic coat thoroughly to completely cut off the temperature detect switch (TDS) and the contacting between the shell metalwork of generating heat of outer casing electrification, and adopted electric heating part has promptly been twined the hermetically sealed of Electrothermic wire ceramic inner pipe, and seal is the material of ceramic size, so the utility model good insulation preformance, safety, and can not wear out, humidity resistance is good simultaneously.Because the utility model adopted ceramic coat, the ceramic inner pipe of ceramic heating parts is separated its each parts and hermetically sealed with ceramic size, thereby has been solved the drawback that existing PTC heater element damages easily, service life is short.
The utility model has the advantages that it has the safety condition of hot operation and temperature control accurate, the good insulation performance condition arranged and be not subjected to the influence of temperature, humidity and working time length that service life is safe and reliable, and is practical.
