Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and examples, it is right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Fig. 1 is shown for the injection system of pancake moulding material, including glue injection units, is arranged on glue injection units one end
Note wind devices (not shown) and be arranged on the follow-up mould sections 3 of the glue injection units other end；Glue injection units are logical with follow-up mould sections 3
The mode for crossing 26 (screws) of sealed connection is connected.Note wind devices are air compressor.
Glue injection units include being arranged on glue injection units one end for feeding and noting the import 25 of wind, and it is another to be arranged on glue injection units
One end is used to connect the outlet of follow-up mould sections 3 and discharging, and the glue injection cavities 29 of connection are provided between import 25 and outlet；Import
25th, glue injection cavities 29 and outlet axle center in the same horizontal line.
The first gum-injecting port 201 for being useful for injection glue, the second gum-injecting port 202 and third note is arranged in parallel in glue injection cavities 29
Glue mouth 203.First gum-injecting port 201, the second gum-injecting port 202 and third gum-injecting port 203 is all mating respectively is provided with pressure sensor
A 21 and the relief valve 22 for adjusting pressure.The first gum-injecting port 201, the second gum-injecting port 202 and the third injecting glue of glue injection cavities 29
The diameter all same of cavity between the mouth diameter of 203 respective chambers and each gum-injecting port 201,202 and 203.First injecting glue
The 201, second gum-injecting port 202 of mouth and third gum-injecting port 203 are so that each section of pressure differential is away from small, object dipping to be glued in glue injection cavities 29
Uniformly, effect is good；
Temperature sensor A 23 and three pressures there are three being correspondingly arranged on interface channel between import 25 and glue injection cavities 29
Force snesor B 24.Temperature sensor A 23 and pressure sensor B 24 is in the both sides of interface channel in setting face-to-face.When one
When the temperature sensor A 23 and the reading of pressure sensor B 24 that group (a pair) is set face-to-face are more than predetermined threshold, wind is noted
System adjusts wind pressure by a small margin；The temperature sensor A 23 and pressure sensor B set face-to-face when two groups or three groups
When 24 reading is more than predetermined threshold, note wind system significantly adjusts wind pressure；Temperature sensor A multiple in this way and pressure
Sensor B can more accurately control the size of wind pressure.Wherein predetermined threshold is the temperature and pressure less than glue injection cavities 29
Numerical value, such as when glue injection cavities temperature is 80 degrees Celsius, predetermined threshold herein is 70 degrees Celsius.
Glue injection cavities 29 are provided with the thermostatic equipment 281 for keeping the regional temperature of outlet constant close to one end of outlet,
Thermostatic equipment 281 is mating to be provided with temperature sensor B 282.Thermostatic equipment 281 makes outlet section region keep constant temperature, and side
It is mating to be provided with temperature sensor B 282, for measuring the temperature of thermostatic equipment 281 and follow-up 3 intersection of mould sections, with cooperation
Thermostatic equipment 281 controls the temperature of flat-temperature zone so as to which the temperature of constant temperature zone be made more to stablize in suitable temperature range；Due to
3 temperature of follow-up mould sections is higher, and thermostatic equipment 281 is not so that the temperature of glue injection cavities 29 is influenced by follow-up mould sections 3, so as to not
Can glue there are the quality problems because of caused by temperature change, so as to ensure that the quality of product after injecting glue；It ensure that and set simultaneously
Standby normal operation.
The outlet die 27 for retaining glue is provided in outlet face-to-face.Outlet die 27 can will be on object be glued
Extra glue is stayed in glue injection cavities 29, will not be taken extra glue in follow-up mould sections 3, be improved product quality；
According to another preferred embodiment of the invention, note wind devices can also be electric air pump.
According to another preferred embodiment of the invention, it can also be flange and pin to be tightly connected 26.
According to another preferred embodiment of the invention, it is correspondingly arranged on the interface channel between import 25 and glue injection cavities 29
Two temperature sensor A 23 and two pressure sensor B 24.Temperature sensor A 23 and pressure sensor B 24 are being connected
The both sides of channel are in setting face-to-face.The temperature sensor A 23 and pressure sensor B set face-to-face when one group (a pair)
When 24 reading is more than predetermined threshold, note wind system is finely adjusted wind pressure；The temperature sensor A set face-to-face when two groups
When the reading of 23 and pressure sensor B 24 is more than predetermined threshold, note wind system carries out wind pressure significantly adjustment (such as Fig. 2 institutes
Show).
A kind of injection system for pancake moulding material of the present invention is in operation：
To be, for example, that bakelite wave plate, bakelite purlin heat in advance when pancakes material is entering injection system wait gluing object
To 50 degrees centigrades.Then one end of pancake material enters from the imports 25 of glue injection units to (object glue is not continuously not
Disconnected enters import 25).Glue is injected from the first gum-injecting port 201, the second gum-injecting port 202 and third gum-injecting port 203, injecting glue
Temperature in chamber 29 is 75-85 degrees Celsius, while notes wind devices and start to be blown into pre-warmed constant temperature wind from import 25, and outside is aobvious
Show each sensor (including temperature sensor A 23, pressure sensor B 24, temperature on the screen (not shown) of showing device
Sensor B 282, pressure sensor A 21) data, when 21 readings of pressure sensor A reach preset value (such as 0.9-
When 0.98Mpa), object to be glued starts to remove to outlet.In exit, extra glue is stayed in glue injection cavities 29 by outlet die 27
In, since glue injection units are continuing injecting glue, there is certain pressure in glue injection cavities 29, glue can be overflowed from import 25；When glue stream
It moves to during import 25, the registration of temperature sensor A 23 and pressure sensor B 24 increase to over predetermined threshold, and note wind devices increase
Big wind pressure seals glue at import 25 up for safekeeping；When the registration of temperature sensor A 23 and pressure sensor B 24 be reduced to it is predetermined
During threshold value (glue no longer overflows), note wind devices reduce wind pressure accordingly, realize real-time and precise regulation and control wind pressure.In injecting glue process
In, when the pressure in glue injection cavities 29 changes (registration of pressure sensor A changes), automatic adjusting pressure release valve 22,
Make the pressure in glue injection cavities 29 constant.Thermostatic equipment 281 close to the flat-temperature zone of outlet so that remain certain temperature (75-
85 degrees Celsius), since follow-up 3 temperature of mould sections is higher than the temperature of glue injection cavities 29, injecting glue can be influenced by being not provided with thermostatic equipment 281
The temperature of glue in chamber 29, so as to make the product after injecting glue, there are mass defects.
The foregoing is merely presently preferred embodiments of the present invention, is not used for limiting the practical range of the present invention；If it does not take off
It from the spirit and scope of the present invention, modifies or equivalently replaces the present invention, should all cover in the claims in the present invention
In protection domain.
