The specific embodiment

With reference now to accompanying drawing, the utility model is described.

As Fig. 1-10, the point gum machine that the utility model provides comprises: stepper motor 9, spacer block 12, the fixed head 1 with blind hole, movable pressing board 2, the Teflon with half slot are led sebific duct 3, runner assembly 4, rotational positioning grip assembly 5, first coupling band 6, second coupling band 7, shock-absorbing sleeve 8, trimmer location-plate 10, trimmer 11, are screwed nut 13, pan head screw 14, control circuit 15, interior hexagonal holding screw 16.

Stepper motor 9, spacer block 12 and fixed head 1 link together by pan head screw 14.First coupling band 6 and second coupling band 7 are fixed on the output shaft of stepper motor 9 and an end of turning cylinder 40 with interior hexagonal holding screw 16 respectively.Connect with shock-absorbing sleeve 8 between first coupling band 6 and second coupling band 7.

Wherein runner assembly 4 comprises: turning cylinder 40, bearing cap 41, bearing holder (housing, cover) 42, needle bearing 43, ball bearing 44, pin 45, sliding bearing 46, needle roller 430.Runner assembly 4 be placed in the blind hole of fixed head 1 and with 42 fastening connections of bearing holder (housing, cover).Needle bearing 43 is fixed on the turning cylinder 40 by pin 45, and two ball bearings 44 are housed between needle bearing 43 inner chambers and the turning cylinder 40, utilizes the cylindrical of ball bearing 44 that needle roller 430 is accurately located on circumference.Turning cylinder 40 penetrates the sliding bearing 46 that is installed in bearing holder (housing, cover) 42 and the bearing cap 41, and two M3 screws 47 of bearing cap 41 usefulness are fixed on the bearing holder (housing, cover) 42, makes needle roller 430 with turning cylinder 40 smooth and easy rotation in bearing holder (housing, cover) 42 holes together.Wherein needle roller 430 can rotation on the retainer of needle bearing 43.

Rotational positioning grip assembly 5 comprises: rotational positioning cover 51, movable sleeve 52, stage clip 53, depression bar 54, fixed axis 55.Rotational positioning grip assembly 5 can rotate around fixed axis 55, and depression bar 54 screws on the movable sleeve 52, and rotational positioning is overlapped in 51 and between the depression bar 54 stage clip 53 is housed, but rotational positioning cover 51 can be moved axially and the resilience playback along depression bar 54.

When rotational positioning grip assembly 5 buckles into the half slot 23 of movable pressing board 2, have and compress Teflon and lead the effect that sebific duct 3 has damping, buffering again, rotate depression bar 54 simultaneously and can regulate the pressure that Teflon is led sebific duct 3, prevent that pressure from crossing ambassador's Teflon and leading sebific duct 3 wearing and tearing and break or reduction of service life according to the plastic emitting situation of reality.

As Fig. 4, when the installation Teflon is led sebific duct 3, should penetrate in " V " shape groove 17 of the trimmer 11 that is installed on the trimmer location-plate 10, regulate trimmer 11 and lead sebific duct 3 with the chucking Teflon, and, lead sebific duct 3 and when runner assembly 4 rotates, do not produce slip or mobile to prevent Teflon with the position that screws nut 13 fastening trimmers 11.

The course of work of the utility model point gum machine is described below.

When being in user mode, movable pressing board 2 levels are put in needle roller 430 surfaces, make movable pressing board 2 20 rotations around the axle center, and rotational positioning grip assembly 5 is buckled in movable pressing board 2, make its semicircle cambered surface 21 compress Teflon and lead sebific duct 3.Step 22 on this movable pressing board 2 is stuck on the bearing holder (housing, cover) 42, thereby plays position-limiting action, makes the semicircle cambered surface 21 of movable pressing board 2 and the minimum distance on needle roller 430 surfaces remain on 0.3mm, prevents that hollow Teflon is led sebific duct 3 to be killed.

Stepper motor 9 is by first coupling band 6, shock-absorbing sleeve 8, with second coupling band 7, when driving the rotation synchronously counterclockwise of turning cylinder 40 and needle bearing 43, make the Teflon that is pressed between movable pressing board 2 and the needle roller 430 lead sebific duct 31 ends and produce the power of extruding, air or glue are flowed out from 31 ends, because of being in vacuum state in its pipe, so air or glue are when 31 ends flow out, the pull of vacuum that produces in the pipe sucks glue or air from 32 ends, when needle roller 430 contiguous circumferential are rotated, make glue transmission in Teflon is led sebific duct 3 continuously, thereby realize some glue function.In like manner, as turning cylinder 40 and needle bearing 43 clockwise directions are rotated synchronously, then produce the power of extruding, and the pull of vacuum that produces in the pipe sucks glue or air from 31 ends at 32 ends.By the rotating speed and the interval rotation time of control circuit 15 control step motors 9, can control glue discharge-amount and glue and spue blanking time.

In addition, described Teflon is led the hollow pipe that sebific duct 3 can be made for corrosion resistant Teflon material.

Above-mentioned point gum machine structure has realized the some glue operation to the lower glue of viscosity, and has higher precision.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
