Description
Technical Field
The utility model relates to a nozzle structure for semi-automatic bottle blowing machine.
Background
At present, the conventional design of the nozzle structure of a PET (polyethylene terephthalate) semi-automatic bottle blowing machine in the industry is that a rubber or polyurethane sealing ring is used for sealing between a nozzle and a mold, and in order to prevent the rubber or polyurethane sealing ring from being damaged by high-pressure air, the inner side and the outer side of the sealing ring are protected by a stainless steel nozzle head. However, excessive protection tends to cause the stainless steel nozzle tip to contact the parison opening, resulting in damage to the parison opening by the nozzle tip, unnecessary waste loss and lost production capacity.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems and providing a nozzle structure for a semi-automatic bottle blowing machine, avoiding the damage of a nozzle head to a bottle blank opening, reducing the rejection rate when blowing the bottle and improving the production efficiency.
The purpose of the utility model is realized like this:
the utility model discloses a nozzle structure for semi-automatic bottle blowing machine, nozzle structure hug closely the bottle base mouth of a bottle base, and the bottle base setting is in a mould, and nozzle structure includes:
a nozzle head, a groove which is right opposite to the bottle blank opening and an annular groove which is arranged around the groove are arranged on the bottom surface of the nozzle head, and an air inlet which is communicated with the groove is arranged on the side wall of the nozzle head;
the sealing ring is arranged in the annular groove and protrudes out of the bottom surface of the nozzle head, the bottom surface of the sealing ring is tightly attached to the top surface of the bottle blank opening, and the inner diameter of the sealing ring is smaller than that of the bottle blank opening; and
a lifting rod partially inserted into the groove from the center of the top surface of the nozzle head.
The nozzle structure for the semi-automatic bottle blowing machine is characterized in that the inner diameter of a bottle blank opening is 39 mm; the internal diameter of the sealing ring is 35 mm.
The nozzle structure for the semi-automatic bottle blowing machine is characterized in that the inner diameter of the groove is 31 mm.
In the nozzle structure for the semi-automatic bottle blowing machine, the sealing ring protrudes 2mm from the bottom surface of the nozzle head.
The nozzle structure for the semi-automatic bottle blowing machine is characterized in that the nozzle head is made of stainless steel.
The utility model discloses following beneficial effect has: the quality defect caused by collision between the nozzle head and the bottle blank opening is reduced, the defective rate is reduced, the production efficiency is improved, the enterprise benefit is improved, and waste of waste products is avoided.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the nozzle structure for a semi-automatic bottle blowing machine of the present invention is shown, the nozzle structure clings to a bottle blank opening 11 of a bottle blank 1, the bottle blank 1 is disposed in a mold 2, and the nozzle structure includes:
a nozzle head 4, a groove 41 which is right opposite to the bottle blank opening 11 and an annular groove 43 which is arranged around the groove 41 are arranged on the bottom surface of the nozzle head 4, and an air inlet 42 which is communicated with the groove 41 is arranged on the side wall of the nozzle head 4;
a seal ring 5 installed in the annular groove 43 and protruding from the bottom surface of the nozzle head 4, the bottom surface of the seal ring 5 clings to the top surface of the bottle blank mouth 11, and the inner diameter of the seal ring 5 is smaller than that of the bottle blank mouth 11; and
a pull-up rod 3 partially inserted into the recess 41 from the center position of the top surface of the nozzle head 4;
the inner diameter of the bottle blank opening 11 is 39mm, the inner diameter of the sealing ring 5 is 35mm, and the inner diameter of the groove 41 is 31 mm;
the sealing ring 5 protrudes 2mm from the bottom surface of the nozzle head 4;
the nozzle head 4 is made of stainless steel;
the sealing ring 5 is made of rubber.
The utility model discloses a when the nozzle structure of semi-automatic bottle blowing machine used, push down nozzle head 4 through the pull-up rod 3, make sealing washer 5 and bottle base 1's bottle base mouth 11 in close contact with, simultaneously because the internal diameter of sealing washer 5 is less than the internal diameter of bottle base mouth 11, and sealing washer 5 salient in nozzle head 4's bottom surface 2mm, even nozzle head 4 and bottle base mouth 11 aim at the inaccuracy, nozzle head 4 still can not touch bottle base mouth 11 under the state that compresses tightly, the damage of bottle base mouth 11 has been avoided, the defective index has been reduced, and the production efficiency is improved, and the enterprise benefit is improved.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
