Above-mentioned pump chamber 26 is for configuring internal rotor 21 and external rotor 22.Wherein, internal rotor 21 centers are to be fixed on a transmission shaft 23, and utilize bearing transmission shaft 23 to be hubbed on the metal module 201,202 of pump chamber 26 both-ends, this transmission shaft 23 can externally connect such as being the rotating drivers such as motor, speed reducer, makes internal rotor 21 can be located in the interior driving of accepting motor of this pump chamber 26 and rotation.
Further, as shown in Figure 3, expose the internal gear that internal rotor 21 can be cycloid gear pump, the outer flank of tooth 210 that is formed with the arc concave contour on its peripheral wheel face around; In Fig. 2, a side wall that also discloses internal rotor 21 is formed with the annular groove 211 with transmission shaft 23 concentrics, and utilizes annular groove 211 groups to establish an internal rotor pad 24, makes internal rotor pad 24 to contact with a side wall 263 of this pump chamber 26.
Further, the part of the end wall 263 of pump chamber 26 can be to consist of a pump chamber pad 25, makes internal rotor pad 24 contact with pump chamber pad 25.At this, must illustrate in detail, pump chamber pad 25 can not exist yet, and internal rotor pad 24 is directly contacted with the end wall 263 of pump chamber 26; In other words, as long as can utilize internal rotor pad 24, or utilize internal rotor pad 24 and pump chamber pad 25 to come interval internal rotor 21 and the end wall 263 of pump chamber 26 to come in contact, all belong to design scope of the present utility model.
Refer to Fig. 4, disclose the interval via internal rotor pad 24, can make to possess a gap h1 between the end wall 263 of distolateral and pump chamber 26 of internal rotor 21, to avoid internal rotor 21, contact the end wall of pump chambers 26.
Except this, refer to Fig. 6, disclose the utility model in further implementing, also can take two internal rotor pads 24 and be located at respectively in the annular groove 211,212 that the bilateral end wall of internal rotor 21 offers, fully avoid internal rotor 21 and the bilateral end wall 263,264 of pump chamber 26 to come in contact.
Then, please again merge and consult Fig. 2 and Fig. 3, the external gear that this external rotor 22 can be cycloid gear pump is described, make external rotor 22 there is the outer wall 221 of loop, and the inner toothed surface 220 that the inboard of external rotor 22 is formed with the arc concave contour around, and external rotor 22 is hubbed on the link spring shape end wall 265 of pump chamber 26 according to its outer wall 221, and the inner toothed surface 220 of external rotor 22 is meshed with the outer flank of tooth 210 parts of internal rotor 21, in order to utilize internal rotor 21 to drive external rotor 22 rotations.
In addition, in Fig. 2 and Fig. 3, the outer wall 221 that also discloses external rotor 22 is formed with an annular groove 222, and utilizes annular groove 222 groups to establish an external rotor pad 27, makes external rotor pad 27 to contact with the link spring shape end wall 265 of these pump chamber 26 1 sides.
Please continue and consult Fig. 5, disclose the interval via external rotor pad 27, can avoid the link spring shape end wall 265 of the outer wall 221 contact pump chambers 26 of external rotor 22.
In above-mentioned enforcement, internal rotor pad 24 is that the half hitch crystal formation engineering plastics (polyaryletherketone is called for short Peek) that uses the functional group with ketone and phenol is made with external rotor pad 27; Further, Peek is a kind of engineering plastics used under hot environment, can the temperature under 260 ℃ use continuously, and there is good anti-chemistry, stability (discharging hardly toxic gas and smog), good electrical properties, mechanical property, wear resistance performance, high-purity, and easy processing.Therefore, the internal rotor pad made with Peek 24 is suitable for filling out in pump chamber 26 environment that are loaded with about 160 ℃ of hot melt adhesive with external rotor pad 27 utmost points and uses, and can possess working life durable, abrasion performance.
Because the cycloidal gear pump characteristics is to make the internal rotor 21 be meshed adopt eccentric configuration with external rotor 22, therefore, the part be not meshed with the outer flank of tooth 210 in inner toothed surface 220, a plurality of backlash a that can form from small to large and arrange in the form of a ring from large to small again; Further, the details that backlash a distributes for the benefit of is described, refer to Fig. 3, illustrate that described a plurality of backlash a sequentially comprises large backlash a1, middle backlash a2, little backlash a3 and minimum backlash a4, these backlash a sequentially is distributed between this entrance 261 and outlet 262 from large to small, wherein large backlash a1 and entrance 261 are connected, and little backlash a3 or little backlash a3 are connected with minimum backlash a4 and outlet 262.Furthermore, when internal rotor 21 bias drive external rotor 22 time rotationals, what large backlash a1 was constant keeps being connected with entrance 261, and little backlash a3 or with outlet 262 maintenances be connected constant with minimum backlash a4 of little backlash a3.
Then, refer to Fig. 7 to Fig. 9, illustrate by above-mentioned configuration, when internal rotor 21 eccentric drive external rotor 22 rotations, and the hot melt adhesive S of glue bucket 4 heat collector 3 heating as shown in Figure 1, entrance 261 via gumming pump 2 is written in large backlash a1 subsequently, now, following the turning operation of internal rotor 21 and external rotor 22, to little by little the volume of large backlash a1 be reduced into to middle backlash a2, continue the volume of middle backlash a2 is little by little reduced into to little backlash a3, moreover, the volume that little backlash a3 also incites somebody to action little by little reduces into minimum backlash a4, now, hot melt adhesive S is also sequentially by large backlash a1, middle backlash a2, little backlash a3 and minimum backlash a4 are extruded the outlet 262 that is passed to gumming pump 2, so that by the reduction of backlash volume, obtain the accurate control of hot melt adhesive S to pressure and the flow of glue, and then hot melt adhesive S is passed to coating nozzle (not disclosing), and then be coated on glass substrate.
In utilizing above-mentioned gumming pump 2 confession glue processes, be in particular under durable use, approximately the hot melt adhesive of 160 ℃ of meltings is also born the molten warm impact of hot melt adhesive via also making in pump chamber 26 in described backlash a transmittance process, for this reason, the utility model is especially by possessing the internal rotor pad 24 of wear resistance, the configuration of external rotor pad 27, intercept internal rotor 21, the end wall 263 of external rotor 22 and pump chamber 26, the abrasion phenomenon occurs between 265, effectively promote internal rotor 21, the end wall 263 of external rotor 22 and pump chamber 26, 265 abrasion resistances under described molten temperature environment, in order to enhance the durable working life of the gumming pump 2 configured in the hot melt glue spreading machine.
To sum up institute is old, is only preferred embodiment of the present utility model, not in order to limit the utility model; All other do not break away from the equivalence completed under the spirit that the utility model discloses to be modified or displacement, all should be contained in claims scope required for protection.
