Description
Technical field
The utility model relates to a kind of hot melt glue spreading rifle, specifically is meant a kind of hot melt glue spreading rifle with fine adjustment mechanism.
Background technology
Traditional pneumatic open-close hot melt glue spreading rifle is to make needle and copperhead go into Jiao Kou to open, cut out the plastic emitting that realizes coating gun, end glue by high pressure gas.The size of gel quantity is gone into glue mouth openings of sizes with copperhead and is controlled by regulating the needle link to each other with piston, just by regulating the position realization of adjusting rod.Because the frequent back and forth movement of needle in the production process, needle and adjusting rod produce frequent impact, and the adjusting rod of traditional hot-melt adhesive coating gun tends to occur positioning, thereby can not obtain gel quantity accurately, have a strong impact on the gluing quality of production, and can cause the waste of PUR.Therefore, a kind of hot melt glue spreading rifle that can accurately control the gel quantity size of design has crucial meaning for the quality of production that improves gluing, reduction gluing production cost.
Summary of the invention
The purpose of this utility model is the hot melt glue spreading rifle that proposes a kind of band fine adjustment mechanism of energy fine adjustment gel quantity size.
The purpose of this utility model is achieved in that this hot melt glue spreading rifle is made up of fine adjustment mechanism, main gunlock structure, copperhead mechanism and gluing nozzle mechanism, connects with screw between them.Fine adjustment mechanism by knurled knob, steady pin, fixed cover, adjusting rod, bonnet, interstage sleeve, sealing shroud, hold spring and alignment pin etc. tightly and form.The adjusting rod of fine adjustment mechanism is connected by steady pin with fixed cover, is pressed into by interference fit in the corresponding aperture of knurled knob; The alignment pin upper end is held spring tightly and is inserted on the step of fixed cover through interstage sleeve in interstage sleeve inserts the elliptical aperture of fixed cover, holds spring tightly alignment pin is held tightly.It is on the basis of traditional pneumatic open-close hot melt glue spreading gunlock structure, adorns a fine adjustment mechanism on bonnet.In the time will transferring big or turn the gel quantity of coating gun down, only need manually clockwise or be rotated counterclockwise the bonnet knurled knob, the size of gel quantity can make alignment pin change with respect to the angle of bonnet annular knurl to control by regulating knurled knob.After adjusting finished, knurled knob was motionless, the fixed-site of adjusting rod and needle, and at this moment, alignment pin annular knurl groove bottom land corresponding with bonnet under the effect of holding spring tightly contacts.Even there is the frequent back and forth movement of needle in the production process, needle and adjusting rod produce frequent impact, and adjusting rod positioning can not occur yet, thereby can obtain gel quantity accurately.
The utility model has the advantages that: by rotating knurled knob alignment pin is changed with respect to the angle of bonnet annular knurl, reach the purpose of regulating the gel quantity size.When the alignment pin revolution is crossed a bonnet annular knurl, can send sound, therefore, the size of gel quantity can realize quantitative adjusting.After adjusting finished, knurled knob was motionless, the fixed-site of adjusting rod and needle, and at this moment, alignment pin annular knurl groove bottom land corresponding with bonnet under the effect of holding spring tightly contacts.Even there is the frequent back and forth movement of needle in the production process, needle and adjusting rod produce frequent impact, and adjusting rod positioning can not occur yet, thereby can obtain gel quantity accurately.

The specific embodiment
Referring to accompanying drawing, be example with the coating gun: the hot melt glue spreading rifle of band fine adjustment mechanism mainly partly is made up of fine adjustment mechanism 24, main gunlock structure 25, copperhead mechanism 26 and gluing nozzle mechanism 27 etc., and each several part all connects with screw.
Fine adjustment mechanism 24 comprises: knurled knob 1, steady pin 2, fixed cover 3, adjusting rod 4, bonnet 5, interstage sleeve 6, sealing shroud 7, hold spring 22, alignment pin 23 tightly.Main gunlock structure 25 comprises: main body 8, piston 9, piston rod 10, needle 11, main rifle are gone into glue mouth 17, following air inlet 18, piston cavity of resorption 19, are gone up air inlet 20, piston upper chamber 21.Copperhead mechanism 26 comprises: copperhead 12, copperhead are gone into glue mouth 13.Gluing nozzle mechanism 27 comprises: spray nozzle 14, curtain coating road 15, gum outlet 16.
The adjusting rod 4 of fine adjustment mechanism 24 is connected by steady pin 2 with fixed cover 3, is pressed into by interference fit in the corresponding aperture of knurled knob 1.Insert in the elliptical aperture 28 of fixed cover 3 alignment pin 23 upper ends, by interstage sleeve 6 it is not taken off down, holds tightly on the step that spring 22 is inserted in fixed cover 3, by interstage sleeve 6 it is not taken off down, holds spring 22 tightly and make alignment pin 23 be in the state of holding tightly.Be connected by pressing between interstage sleeve 6 and the fixed cover 3.Between adjusting rod 4 and the bonnet 5 with being threaded.When the hot melt glue spreading rifle is worked, high pressure gas enters piston cavity of resorption 19 from the following air inlet 18 of main rifle, promote to move on piston 9 and the piston rod 10, when collide in piston rod 10 upper ends and adjusting rod 4 lower ends, piston rod 10 is gone into glue mouth 13 openings with copperhead and is reached maximum, simultaneously, high moulding is gone into glue mouth 17 from main rifle and is entered copperhead and go into glue mouth 13, and the gluing work are realized to gum outlet 16 in the curtain coating of flowing through road 15.If gel quantity is increased, then rotate counterclockwise knurled knob bonnet 5, at this moment, move on the adjusting rod 4, piston rod 10 is gone into glue mouth 13 maximum open amounts with copperhead and is increased; On the contrary, if gel quantity is reduced, then clockwise rotate knurled knob 1, at this moment, adjusting rod 4 moves down, and piston rod 10 is gone into glue mouth 13 maximum open amounts with copperhead and reduced.
When rotating knurled knob 1, alignment pin 23 forces to hold tightly outside the spring 22 under the effect of external force to be opened, alignment pin 23 is crossed the groove top from the annular knurl bottom land of bonnet 5 and is arrived adjacent bonnet annular knurl bottom land, sends sound one time, and adjusting rod 4 moves up or down corresponding displacement.The size that alignment pin 23 revolutions are crossed a groove adjusting rod 4 amount of movements can realize by the pitch that changes adjusting rod 4 and bonnet connecting thread.When alignment pin 23 was in the annular knurl bottom land of bonnet 5, if do not apply moment of torsion on knurled knob 1, because the effect of holding tightly of holding spring 22 tightly, adjusting rod 4 was in self-locking state.Even there is the frequent back and forth movement of needle 11 in the production process, needle 11 produces frequent impact with adjusting rod 4, and adjusting rod 4 positioning can not occur yet, thereby can obtain gel quantity accurately.
