Description

Gluing machine

Technical field the utility model relates to two-layer at least variety classes thin material is laminated with the all-in-one-piece laminator, relates in particular to the gluing machine that picture, photo or file outside surface is laminated with again transparent membrane.

The background technology gluing machine generally all is provided with the well heater 2 of at least one pair of rubber rollers 1 and this rubber rollers temperature of raising for thermoplastic film firmly is laminated with in photo or file outside surface in it, see Fig. 1.After the start, well heater 2 makes rubber rollers 1 reach uniform temperature, and pilot lamp " READY " (ready) is lighted, and workpiece 8 (photo or file) is covered with transparent membrane and promptly can fills in from described gluing machine import.Two rubber rollers 1 of Zhuan Donging are not only drawn workpiece 8 and are advanced toward outlet in opposite directions; its temperature is with the seasonal described film surface viscous that becomes; thereby it is fitted tightly in workpiece 8 surfaces, and form the adhesive strip that seals, protect described workpiece no longer to be affected by the external environment at workpiece 8 peripheries.

It is to adopt the heater element of PTC (positive temperature coefficient ceramic heater) as well heater 2 that prior art has a class, and well heater 2 adjacent rubber rollers 1 are installed.Bigger with this scheme initial heating power, along with temperature rises, power reduces gradually, finally can reach stabilized operating temperature.But there is a critical defect, promptly after the gluing machine continuous working, in case PTC resistance cross critical point and cause temperature to drop in the time of must reheating, its again heat time heating time very long, allow the user be unequal to waiting for, thereby the requirement that does not meet preheating time short (in 8 minutes) and use continuously.

It is to adopt metallic resistance silk or the quartz ampoule heater element as well heater 2 that prior art has a class in addition, and well heater 2 same adjacent rubber rollers 1 are installed, and nearby temperature controller 3 are installed at well heater 2, generally are bimetallic strip break contact θ, see Fig. 2.Can high-power preheating with this scheme, can use in the short time.But, the product of commercially available this scheme of usefulness has following shortcoming: 1. because well heater 2 power are big, its " Yu Wen " effect is also remarkable, when stopping to heat, the Yu Wenhui of well heater 2 makes the temperature of rubber rollers 1 continue to rise, the result makes the amplitude of rubber rollers 1 temperature dipping and heaving bigger, therefore crosses colloid amount instability.2. because well heater 2 matrixes are to be made of metal, the heat absorption of metal, radiating effect is better than rubber rollers 1, so when real work, well heater 2 is not exclusively synchronous with rubber rollers 1 both temperature variation, add and use high-power heating element, more strengthened temperature fluctuation gap between the two, and temperature controller 3 normally directly places on the well heater 2, what temperature controller 3 reality were grasped is the temperature variation of well heater 2, rather than the temperature variation of rubber rollers 1, so well heater 2 is difficult to cooperate the break contact θ of temperature controller 3 to make " ready " pilot lamp HL2 accurately show state of living in, caused the glue effect bad, the quality instability.3. then make cost improve as increasing additional means, still had problem appearance such as colloid amount instability simultaneously.

A prior art class again is to adopt Power Electronic Technique to control high-power well heater 2 stable heating, can conveniently reach and accurately maintain design temperature, can use continuously, but must be used switching devices such as SCR (thyristor), TRIAC (bidirectional thyristor) and relay, and thermistor, temperature-sensitive electric capacity equitemperature senser element, with high costs.

Summary of the invention the objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of the heat-conducting medium of nearby putting a cheapness at temperature controller and can reach the equilibrium temperature and the gluing machine of high-quality use continuously rapidly, without any need for electronic temperature sensing, temperature-controlling system.

The purpose of this utility model can be by realizing by the following technical solutions: design, make a kind of gluing machine, comprise at least one pair of rubber rollers, be no less than a tool well heater, and temperature controller, especially, also comprise heat-conducting medium, the adjacent described well heater setting of this heat-conducting medium, described temperature controller is close to described heat-conducting medium again and is fixed.

The heat absorption of described heat-conducting medium, the heat radiation physical characteristics close with rubber rollers, in the unit interval, heat-conducting medium can become roughly stable proportionate relationship with the temperature variation of rubber rollers, so accurately grasped the temperature variation that the temperature variation of heat-conducting medium just is equivalent to accurately grasp rubber rollers.

Compare with prior art, the advantage of the utility model gluing machine is: 1. only install a small pieces cheap material additional on traditional structure and do not have complexity, expensive electronic temperature sensing, temperature-controlling system, thereby cost is very low; 2. can the Fast Heating rubber rollers also make accurate, the demonstration in time of " ready " pilot lamp; 3. working temperature is stable, can use continuously.

Description of drawings Fig. 1 is the schematic cross-sectional view of prior art gluing machine structure; Fig. 2 is the schematic cross-sectional view of the utility model gluing machine structure; Fig. 3 is the electrical connection schematic diagram of described gluing machine well heater 2, temperature controller 3 and each pilot lamp, and number in the figure 5 is heat-conducting mediums that the utility model adds.

The common gluing machine of embodiment all adopts high-power heating, well heater 2 matrixes (common metal aluminium or copper) temperature rises very fast, can't with the temperature of rubber rollers 1 synchronously or equal proportion rise, temperature controller 3 (break contact θ) but just make rubber rollers 1 reach serviceability temperature after must repeatedly moving.The escape first time that this means temperature controller 3 is not represented " READY " (ready).Equally, suspend when using, well heater 2 can not cool off with rubber rollers 1 synchronously yet.

The most preferred embodiment of the utility model is shown in Fig. 2 and 3, comprise at least one pair of rubber rollers 1, be no less than a tool well heater 2, and temperature controller 3, especially, also comprise heat-conducting medium 5, these heat-conducting medium 5 adjacent described well heaters 2 are provided with, and described temperature controller 3 is close to described heat-conducting medium 5 again and is fixed.Described temperature controller (3) is a kind of heat sensitive moving breaker point.Normally a kind of ceramic sheet material of described heat-conducting medium 5 or a kind of high molecular polymer or fiber reinforcement type high molecular polymer (FRP), its characteristic is that thermal capacity is big, and heat absorption is slow, and it is also slow to dispel the heat.S is a power switch among Fig. 3, and HL1 is a power light, and R is the heating resistor of well heater 2, and HL2 is " ready " pilot lamp; R or C are used to keep a small amount of heating current.After well heater 2 heatings, transmit heat to described rubber rollers 1 and heat-conducting medium 5 respectively, because the heat absorption of heat-conducting medium 5, the heat radiation physical characteristics is close with rubber rollers 1, so their temperature synchronously or roughly equal proportion rises, 3 of temperature controllers fixedly contact with heat-conducting medium 5, it does not have any contact with well heater 2, therefore temperature controller 3 temperature of being reacted is actually the temperature of heat-conducting medium 5, during work, the temperature of temperature that it measures and rubber rollers 1 has the synchronized relation of quite stable, thereby can be the not too not fast escape of temperature controller 3, and pilot lamp " READY " can reflect the serviceable condition of gluing machine more exactly, therefore just can reach the purpose of control with a temperature controller.

The utility model in use, the temperature of heat-conducting medium 5 is in case arrive default temperature controller escape temperature, control circuit just can cut off the power supply source of well heater 2, make well heater 2 stop heating, relay indicating light " READY " lights simultaneously, the expression preheating or again heating process finish, the indication user can start working.When the temperature of heat-conducting medium was lower than temperature controller escape temperature, well heater 2 was connected and is begun to continue heating, and relay indicating light " READY " extinguishes.

Facts have proved, improve the prior art gluing machine according to technical solutions of the utility model, its preheating setup time can be satisfied request for utilization fully, and running hours to cross the colloid amount very stable, but no longer have aforementioned various disadvantage.
