Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.Obviously, the described embodiments are only a part of the embodiments of the utility model,
Instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creation
Property labour under the premise of the every other embodiment that is obtained, shall fall within the protection scope of the present invention.
Embodiment one
As shown in Figure 1, for the first embodiment of glue dispensing valve provided by the embodiment, the glue dispensing valve includes valve body 1, the valve
The lower part of body 1 is equipped with nozzle 4, and nozzle cage 2 is arranged with outside the nozzle 4, and the nozzle cage 2 is equipped with heating device.
Referring to figure, 2, Fig. 3 and Fig. 4, the heating device includes electric heating film 3, hold assembly 5, temperature sensor 6 and control
Device 7 processed, the controller 7 are separately connected the electric heating film 3 and the temperature sensor 6.The electric heating film 3 closely pastes
On the outside of the peripheral wall for investing the nozzle cage 2, the temperature sensor 6 is set to the peripheral wall of the electric heating film 3 and the nozzle cage 2
Between.
In the present embodiment, the electric heating film 3 is flexible, in this way, being conducive to outside its peripheral wall with the nozzle cage 2
The more good fitting in side, so that it is guaranteed that the glue in the nozzle 4 is heated evenly, so that the viscosity of glue quickly reduces final protect
It is smooth to demonstrate,prove plastic emitting.The electric heating film 3 is C-shaped, and there are two free terminal, two free terminals for the tool of the electric heating film 3
Between gap very little, that is to say, that the electric heating film 3 wraps up the whole on the outside of the peripheral wall of the nozzle cage 2 substantially, in this way
The glue be similarly conducive in the nozzle 4 is heated evenly.
In the present embodiment, the temperature sensor 6 be thermocouple, it is preferred that the temperature sensor 6 choose size compared with
Small thermocouple is bonded the influence of tight ness rating to reduce it to the electric heating film 3 and the peripheral wall to nozzle cage 2.
In the present embodiment, the controller 7 is programmable logic controller (PLC) 7.
In the present embodiment, the heating device further includes hold assembly 5, and the hold assembly 5 is clamped in the electrical heating
So that the electric heating film 3 is adhered closely on the outside of the peripheral wall of the nozzle cage 2 on the outside of the peripheral wall of film 3.The hold assembly 5
It is used including principal arm 51 and from having between two clamping limbs 52 that one end of the principal arm 51 is extended, two clamping limbs 52
In the holding chamber of the accommodating electric heating film 3 and the nozzle cage 2, the end of two clamping limbs 52 is tight by fastener
Gu.The fastener uses bolt, can adjust the holding chamber between two clamping limbs 52 by screwing the fastener
Size, and then adjust the laminating degree between the electric heating film 3 and the nozzle cage 2.In this way, the hold assembly 5 can
To ensure to fit closely between the electric heating film 3 and the nozzle cage 2, prevent the electric heating film 3 and the nozzle cage 2 it
Between the case where loosening.
In the course of work, the temperature that the temperature sensor 6 detects the nozzle cage 2 in real time (is equivalent in the nozzle 4
Glue temperature), and the temperature signal detected is transmitted to the controller 7.The controller 7 is by the temperature signal
It is compared with preset threshold value, is sent out if the temperature signal less than the work of the electric heating film 3 is controlled if the threshold value
Heat with to the glue additional heat in the nozzle 4 so that it is guaranteed that plastic emitting is smooth, if the temperature signal is greater than or equal to described
Threshold value then controls the electric heating film 3 and stops fever to save electric energy to avoid energy waste.
In the present embodiment, the threshold value is set according to the glue in the nozzle 4, and user can be according to currently used
Temperature required by glue sets the threshold value in the controller 7.
Implement glue dispensing valve provided by the utility model, has the advantages that：The controller 7 can control the electricity to add
Hotting mask 3 to the nozzle cage 2 rapidly and uniformly heat glue temperature raising, viscosity reduction so that in the nozzle cage 2,
