Disclosure of Invention
The utility model aims to solve the problems in the prior art and provide a glue mixing and beating head structure, which aims to solve the technical problem of avoiding excessive accumulation of glue at a glue outlet nozzle in the glue beating interval time.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a mix and beat first structure of gluing, its characterized in that includes two inlet pipes, a compounding chamber and a play gluey mouth, inlet pipe and play gluey mouth all are linked together with the compounding chamber, the inlet pipe internal rotation is connected with one and extrudes the screw rod, and the screw direction is opposite for two extrusion screw rods, the one end rotation that extrusion screw rod stretches out the inlet pipe is connected with a gear, two gears intermeshing, and one extrusion screw rod is connected a servo motor's output shaft, be provided with a torsional spring between gear and the extrusion screw rod that links to each other with it.
Further, extrude the screw rod and stretch into to the compounding intracavity, it is provided with the compounding wheel that is located the compounding intracavity to extrude the screw rod on the fixed compounding wheel, the compounding wheel includes a plurality of rim plates that set up alternately along extruding the screw rod axis direction, and the interval between the adjacent rim plates is greater than the thickness of rim plate, and in the interval between the adjacent rim plate of another compounding wheel was inserted to the rim plate part of one of them compounding wheel.
The two mixing wheels are in a staggered state, glue of different components is mixed at the staggered position, mixed for multiple times in the process that the glue moves from the mixing cavity to the glue outlet nozzle, and finally discharged from the glue outlet nozzle; compared with the traditional mixing mode, the high-frequency forced mixing is carried out on the glue with different components, the glue outlet resistance is not too large as a whole, the influence of the glue outlet resistance caused by glue mixing can be overcome by matching with the extrusion mode of the screw, and the proportioning precision is also improved.
In order to avoid glue in the glue beating gap from flowing down to be discharged, or pile up at the end of the glue outlet mouth, make the head and the tail joint department of the annular glue beating area glue the volume is great, this scheme sets up the torsional spring between extrusion screw and the gear, when beginning to beat the glue, the gear is driven, extrusion screw and gear are not synchronous rotation at this moment, torsion spring is twisted earlier, when torsion spring continue torsion required moment of torsion greater than extrusion screw overcome the required resistance of glue and correspond moment of torsion, extrusion screw just begins to rotate, and after beating glue, torsion spring restoring force can drive extrusion screw counter-rotation certain angle, make glue solution part backward flow, thereby make glue part of glue outlet mouth withdraw, in beating glue interval time, glue solution pile up the condition in glue outlet mouth department is alleviated greatly, glue beating homogeneity and precision have been improved, the problem that glue beating regional head and tail joint department glue volume is too much has been avoided.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1-4, the glue mixing and beating head structure comprises two feeding pipes 1, a mixing cavity 2 and a glue outlet nozzle 3, wherein the feeding pipes 1 and the glue outlet nozzle 3 are both communicated with the mixing cavity 2, a connecting pipe is arranged at the upper part of each feeding pipe 1, glue enters the feeding pipe 1 from the connecting pipe, an extrusion screw 4 is rotationally connected with the feeding pipe 1, the spiral directions of the two extrusion screws 4 are opposite, one end of each extrusion screw 4 extending out of the feeding pipe 1 is rotationally connected with a gear 5, the two gears 5 are meshed with each other, one extrusion screw 4 is connected with an output shaft of a servo motor, and a torsion spring 6 is arranged between the gear 5 and the extrusion screw 4 connected with the gear.
The extrusion screw 4 stretches into in the compounding chamber 2, and the fixed compounding wheel 7 that is located in the compounding chamber 2 that is provided with on the extrusion screw 4, compounding wheel 7 include along the alternate a plurality of rim plates 8 that set up of extrusion screw 4 axis direction, interval between the adjacent rim plates 8 is greater than the thickness of rim plate 8, in the interval between the adjacent rim plate 8 of another compounding wheel 7 was inserted to the rim plate 8 part of one of them compounding wheel 7. The cross section of the mixing cavity 2 is 8-shaped, and the inlet of the glue outlet nozzle 3 is positioned at the intersection of the two mixing wheels 7, so that glue solution can be discharged into the glue outlet nozzle 3 only after being mixed.
The two mixing wheels 7 are in a staggered state, glue of different components is mixed at the staggered position, mixed for multiple times in the process that the glue moves from the mixing cavity 2 to the glue outlet nozzle 3, and finally discharged from the glue outlet nozzle 3; compared with the traditional mixing mode, the high-frequency forced mixing is carried out on the glue with different components, the glue outlet resistance is not too large as a whole, the influence of the glue outlet resistance caused by glue mixing can be overcome by matching with the extrusion mode of the screw, and the proportioning precision is also improved.
In order to avoid glue from flowing downwards and being discharged in a glue beating gap, or piling up at the tail end of a glue outlet nozzle 3, the glue quantity at the head-tail joint of an annular glue beating area is larger, a torsion spring 6 is arranged between an extrusion screw 4 and a gear 5 in the scheme, when glue beating starts, the gear 5 is driven, the extrusion screw 4 and the gear 5 do not synchronously rotate, but the torsion spring 6 is twisted first, when the torque required by the torsion spring 6 to continuously twist is larger than the torque corresponding to the resistance required by the extrusion screw 4 for overcoming the glue, the extrusion screw 4 starts to rotate, after the glue beating ends, the restoring force of the torsion spring 6 drives the extrusion screw 4 to reversely rotate for a certain angle, so that the glue quantity at the glue outlet nozzle 3 is partially retracted, the situation that the glue quantity at the head-tail joint of the glue outlet nozzle 3 is piled up is greatly relieved in the glue beating interval time, the uniformity and precision of glue beating are improved, and the problem of excessive glue quantity at the head-tail joint of the glue beating area is avoided.
