Description

Blowing head structure

Technical Field

The utility model relates to the field of glass bottle and can manufacturing, in particular to a blowing head structure.

Background

In the glass bottle production process, positive blowing is taken as the last step of finally blowing to produce a product, and is realized by a positive blowing mechanism, wherein the positive blowing mechanism is a cylinder with a cam, the cylinder can rotate under the action of the cam while moving up and down to drive a blowing head on a blowing arm to press or leave the upper part of a forming die, when the blowing head enters the upper part of the forming die, a product to be blown is already in the forming die, and the bottle head is higher than the forming die and is limited by the stroke of the blowing mechanism.

In the prior art, as shown in fig. 3, in order to avoid adverse effects caused by overlong blowing pipes, only shorter blowing pipes can be used, so that thin shoulders can appear during production of thin and high bottles, the size of a bottleneck cannot be effectively controlled during production of long-neck bottles, the defects of inner wall depression and the like are generated, the sealing of the bottleneck is affected, and the production is severely restricted by the problems, and the product quality is affected.

SUMMERY OF THE UTILITY MODEL

The present invention aims to solve the above technical problem at least to some extent. Therefore, the utility model provides a blowing head structure, which can prevent a bottle mouth from being broken due to overlong blowing pipes, realize the production of slim and tall bottles and long-necked bottles by the long blowing pipes and further ensure the quality of produced products.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a structure of air blowing head is characterized in that:

the inner center of the blowing head is provided with three communicated pore passages from top to bottom, the three communicated pore passages comprise an upper pore passage, a middle pore passage and a lower pore passage, the middle pore passage can accommodate a single blowing pipe to pass through and serve as a guide hole of the blowing pipe, the pore diameter of the middle pore passage is smaller than that of the upper pore passage and that of the lower pore passage, the blowing pipe vertically and movably penetrates through the guide hole, the lower pipe section can penetrate through the lower pipeline and is exposed out of the blowing head, the upper pipe section extends into the upper pore passage, the limiting block is fixedly sleeved at the outer end of the upper pipe, the blowing pipe is sleeved with a spring, the spring is tensioned between the lower end of the limiting block and the bottom end of the upper pore passage, and when the blowing pipe is in a natural state, the lower pipe section of the blowing pipe retracts into the lower pore passage.

Furthermore, the top end of the upper pore passage is correspondingly provided with a limiting stop sheet according to the position of the limiting block, and the limiting stop sheet abuts against the limiting block and serves as a limiting structure when the air blowing pipe moves upwards.

Compared with the prior art, the utility model has the beneficial effects that:

the air blowing pipe is integrated in the air blowing head, the air blowing pipe can extend downwards to be exposed out of the air blowing head when air is blown forwards, and the air blowing pipe can be driven to retract upwards into the air blowing head by utilizing the elasticity of the spring when the air blowing is stopped, so that the bottle opening is not damaged when the air blowing pipe moves under the condition of ensuring the length of the air blowing pipe, the defects of bottle opening breakage, opening explosion and the like caused by overlong air blowing pipe are avoided, meanwhile, the air blowing pipe and the air blowing head are integrated together, the air blowing pipe does not need to be replaced independently, and the operation is more convenient.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to fig. 2, the blowhead structure of the present embodiment is configured as follows:

the air blowing head 1 is internally and centrally provided with three communicated pore passages from top to bottom, and comprises an upper pore passage 2, a middle pore passage 3 and a lower pore passage 4, wherein the middle pore passage 3 can accommodate a single air blowing pipe 5 to pass through, and is used as a guide hole of the air blowing pipe 5, the pore diameter is smaller than the pore diameters of the upper pore passage 2 and the lower pore passage 4, the air blowing pipe 5 is vertically and movably arranged in the guide hole in a penetrating manner, a lower pore passage can penetrate through the lower pipeline to be exposed out of the air blowing head 1, an upper pore passage extends into the upper pore passage 2, a limiting block 7 is fixedly sleeved outside the upper pore end, a spring 6 is sleeved outside the air blowing pipe 5, the spring 6 is tensioned between the lower end of the limiting block 7 and the bottom end of the upper pore passage 2, and when the air blowing pipe 5 is in a natural state, the lower pore passage of the air blowing pipe 5 retracts into the lower pore passage 4.

Further setting, the top of upper portion pore 2 corresponds according to the position of stopper 7 and is provided with spacing separation blade 8, and spacing separation blade 8 supports and keeps out in stopper 7, and limit structure when making gas blow pipe 5 upwards displacement makes gas blow pipe 5 can not upwards pop out by spring 6.

In specific implementation, when the embodiment is applied to the positive blowing operation of the glass bottle and can production process, the working principle is as follows:

after the bottle enters the molding, the positive blowing arm starts to move downwards along the cam path and simultaneously rotates, the blowing pipe 5 is kept in a retraction state under the action of the spring 6, when the blowing head 1 is pressed on the bottle mouth, positive blowing starts, compressed air is blown in, the blowing pipe 5 slides downwards under the pushing of the compressed air and extends out of the blowing head 1, and the spring 6 is compressed at the moment. When the positive blowing is stopped, the blowing pipe 5 is bounced upwards under the action of the elastic force of the spring 6 and retracts into the lower hole channel 4 again, and at the moment, the positive blowing arm moves upwards. In the whole motion process, gas blow pipe 5 remains the withdrawal state throughout, can not touch the bottleneck, and when just blowing, can stretch out downwards again, and gas blow pipe 5 stretches into the bottleneck when realizing just blowing darker, can not the quality problems when producing pin-point bottles and flask, has improved product, quality, has promoted the product quality.

While embodiments of the utility model have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the claims and their equivalents.
