Embodiment
See also illustrated in figures 1 and 2ly, they are the structural representation of production unit of the bar-shaped polyester thermosol with high smelting point of the utility model and the structural representation of 10 parts of forcing machine wherein.The production unit of the bar-shaped polyester thermosol with high smelting point of the utility model is made up of forcing machine 10, a cooling trough 20, sizing towing mechanism 30, fixed-length cutting device 40.
Described forcing machine 10 is container-like, is made up of feed zone 101, compression section 102, homogenize section 103, and the front portion of forcing machine 10 is provided with a delivery port 11, and delivery port 11 is arranged in feed zone 101, and the polyester hot-melt adhesive particle adds to advance forcing machine 10 from delivery port 11; Barrel 12 is set in forcing machine 10, conveying screw rod 13 is set in the barrel 12, conveying screw rod 13 drives rotation by motor (not shown), and the effect of conveying screw rod 13 is by the rotation of screw rod 13 the polyester hot-melt adhesive particle of sending into to be pushed ahead in the mode of extruding; Conveying screw rod 13 is provided with plus thread 131 and minus thread 132, minus thread 132 is arranged on the position of conveying screw rod 3/13rds 5, promptly be arranged in the compression section 102 of forcing machine 10, its effect is that the polyester hot-melt adhesive particle of the preliminary extruding of the process that will be sent here by conveying screw rod 13 is to pusher, in the present embodiment, the length of minus thread 132 is a week half, because the effect of the pusher of minus thread 132 extruding, make polyester hot-melt adhesive particle further extruding and homogenizing, to remove gas wherein.
One forcing machine venting hole 141 is set on forcing machine 10, corresponding is, one barrel venting hole 142 is set on barrel 12, and, on forcing machine venting hole 141, connect a vacuum pump for vent 15 is set, carry out vacuum suction by vacuum pump, thereby when the hot melt rubber stick moulding, get rid of residual gas in the barrel 12 of forcing machine 10; In the present embodiment, forcing machine venting hole 141 on the forcing machine 10 is arranged on 3/5ths position of forcing machine 10 housings, barrel venting hole 142 on the barrel 12 also is arranged on the position of barrel 3/12nds 5, forcing machine venting hole 141 is corresponding with barrel venting hole 142, and, barrel venting hole 142 extends to both sides, its length range is 50 millimeters～60 millimeters, between forcing machine venting hole 141 and barrel venting hole 142, be connected by two ship shape plates 143, one hole 144 is set respectively on two ship shape plates 143, two ship shape plates 143 are 30 degree with the angle of transverse horizontal face, form the leg-of-mutton vacuum vent holes 145 of Eight characters shape thus between forcing machine 10 and barrel 12, this vacuum vent holes 145 is connected with vacuum pump 15 and communicates.
End at forcing machine 10 is provided with a hot melt adhesive sizing die head 16, it receives the polyester hot-melt adhesive of being sent here by conveying screw rod 13 through extruding and homogenizing, because the polyester hot-melt adhesive of this moment not only pushes and homogenizing, make and do not have gas and bubble in the polyester hot-melt adhesive substantially, simultaneously, the 16 middle part internal diameter processing of hot melt adhesive sizing die head are meticulous, therefore do not have entrapped air pockets in the hot melt adhesive adhesive tape 51 of hot melt adhesive sizing die head 16 moulding, and hot melt adhesive adhesive tape 51 outside surfaces of moulding are bright and clean.
Described cooling trough 20 is arranged on forcing machine 10 back, its effect is that forcing machine 10 hot melt adhesive sizing die heads 16 moulding hot melt adhesive adhesive tape 51 are carried out cooling process, in cooling trough 20, be provided with many to guide deflection sheave 21, they escort with hot melt adhesive adhesive tape 51 in cooling trough 20 through forming cooled hot melt adhesive adhesive tape 52.
Please in conjunction with Fig. 1 referring to shown in Figure 3, described sizing towing mechanism 30 is positioned at cooling trough 20 rear portions, form by motor 32 and traction element 31, for the external diameter of the hot melt adhesive adhesive tape 51 that makes moulding is consistent, in the present embodiment, what the motor 32 of sizing towing mechanism 30 adopted is stepless speed-change motor, and it can make extrusion capacity and pulling speed synchronous, can accurately control the external diameter of hot melt adhesive adhesive tape 51 thus.
See also shown in Figure 1ly, described fixed-length cutting device 40 is arranged on sizing towing mechanism 30 rear sides, in order to will cut into bar-shaped polyester thermosol with high smelting point 53 products through the hot melt adhesive adhesive tape 52 behind the sizing towing mechanism 30 as requested.
The production unit of the bar-shaped polyester thermosol with high smelting point of the utility model is principle and to make the moulding process of polyester hot-melt adhesive rod as follows separately:
The reason that produces bubble in the polyester hot-melt adhesive rod is, is granular raw material owing to become the preceding added polyester hot melting of glue rod, and when pellet entered barrel 12, the air between the pellet gap entered barrel 12 with pellet, and wherein the part air just forms bubble in the glue rod.To this, the utility model is owing to process plus thread 131 in three positions of the first five branchs of screw rod 13, reprocess all half minus threads 132 then in 3/5ths positions of screw rod 13, connect plus thread 131 behind the minus thread 132 again, thereby pellet compression extruding is made it homogenize; And 3/5ths places at forcing machine 10, between forcing machine 10 and barrel 12, form the leg-of-mutton vacuum vent holes 145 of Eight characters shape, this vacuum vent holes 145 communicates with vacuum pump 15, therefore, when advancing to ship shape plate 143, the fused sizing material is obstructed, then go out screw rod 13 in the inclined hole 144 of sizing material with the first ship shape plate 143 and enter ship shape plate 143, walk around 132 sections of the minus threads of screw rod 13,16 extrude until getting to know by returning barrel 12 in the inclined hole 144 of the second ship shape plate 143 again, air in the barrel 12 then can advance people's minus thread 132 from screw rod 13 gap locations, because of minus thread 132 is negative pressure, so air is discharged from venting port 145.
And, because forcing machine 10 each section temperature controlling are relevant with melt viscosity, the fusing point of polyester hot-melt adhesive, the Heating temperature height, the glue of extruding rod any surface finish, but easily cause viscosity to hang down not easy-formation and cooling; Heating temperature is low; Extrude and make things convenient for easy-formation, but surface ratio is more coarse.For this reason, the temperature of the utility model strict control forcing machine 10 each sections in moulding process, more suitable bar-shaped each section of polyester hot-melt adhesive moulding process temperature control is as follows:
Feed zone: 90 ℃～120 ℃;
Compression section: 150 ℃～160 ℃;
Homogenize section: 130 ℃～150 ℃;
Die head: 100 ℃～120 ℃.
By the bar-shaped polyester hot-melt adhesive of above-mentioned explained hereafter, any surface finish exquisiteness will can be operated in its pistol type heat seeling coating device of packing into smoothly, and the coating adhesiveproperties is good.The production unit of the bar-shaped polyester thermosol with high smelting point of the utility model because minus thread is set, is offered venting hole and vacuum pump for vent on forcing machine and barrel on extruder screw in sum, by vacuum suction, makes no bubble existence in the glue rod; Simultaneously, because the motor in the sizing towing mechanism is the stepless speed-change motor synchronous with extrusion capacity, thereby can accurately control the external diameter of hot melt adhesive glue rod; In addition, owing to improved the working accuracy of hot melt adhesive sizing die inner diameter, and, accurately control the temperature of each section of forcing machine and the temperature of hot melt adhesive sizing die head, thereby improved the smooth finish of hot melt adhesive glue rod, therefore very practical.
