Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
The utility model discloses blowing needle 1 of blowing machine is as shown in fig. 4-7, include with the blowing pole 2 of gas blowing device intercommunication and with the air cock 3 of blowing pole 2 intercommunication, air cock 3 is hollow structure, the inside inlet channel 31 that communicates with blowing pole 2 that is equipped with of air cock 3, 3 outer walls of air cock be equipped with be used for with the cutter ring 4 of mould upper end butt, cutter ring 4 is equipped with annular groove with the face of mould butt, (the recess shape can be multiple appearance, the preferred cyclic annular arc recess 41 of adoption of this embodiment) to make blowing forming's the criticism cutting edge of a knife or a sword of production keep away from the bottleneck. This blow needle can make the blowing machine make the bottleneck transition smooth at crowded bottle blow molding's in-process that blows, makes simultaneously criticize the cutting edge of a knife or a sword and keep away from fashioned bottleneck, avoids criticizing the cutting edge of a knife or a sword and cause the scratch to the human body because of bottleneck structure sharpness and bottleneck, influences consumer's experience, and this structure also can improve the sealing performance of crowded bottle blowing simultaneously. Wherein the air tap and the cutter ring of the blowing needle are integrally formed, so that the processing is more convenient and faster.
The cross-sectional shape of the circular arc-shaped groove 41 is composed of a bottleneck inner side arc section 411, a bottleneck top end straight line section 412, a bottleneck outer side arc section 413 and an inclination angle section 414, the connection part of the two adjacent sections is in smooth transition, the inclination angle section inclines outwards, and the inclination angle is 120 degrees. The shaping face of bottleneck forms when being broken with the shear plate by cutter ring, because traditional bottleneck shaping face is the plane, the batch cutting edge of a knife or a sword that its processing produced is located plane bottleneck outside edge, population direct contact bottleneck is by the fish tail easily, and this scheme can let the bottleneck shaping face more in the same direction as smooth through the inboard circular arc section of bottleneck and bottleneck outside circular arc section and inclination section, has avoided the cutting edge of a knife or a sword that criticizes that the bottleneck scope appears simultaneously, strengthens the comfort of mouth contact bottleneck.
The shape of the air inlet passage 31 of the air faucet 3 is that the opening of the air inlet 311 is large, the opening of the air outlet 312 is small, and the air outlet 312 of the air inlet passage 31 adopts an inclined structure, and the inclination angle is 150 degrees. The structure can strengthen the air blown out by the blowing device, so that the blow molding effect is better.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
