Detailed Description

As shown in fig. 1-5, an adjustable gas blowing head for glass bottle production comprises a gas blowing head body 1, wherein a groove 2 used for being sleeved outside a bottle opening is arranged at the bottom of the body 1, a gas exhaust transverse groove 30 penetrating through the outer side wall of the body 1 is arranged on the side wall of the groove 2, the arrangement is similar to that of a traditional gas blowing head, and repeated description is omitted. Be provided with vertical, square centre bore 3 in the body 1, centre bore 3 is selected to set up to square mainly for the convenience carries out spacing direction to slider 5, under the prerequisite that plays the same effect, selects hexagon, other shapes such as pentagon also are feasible.

The central bore 3 extends from the upper surface of the body 1 into the recess 2, i.e. the central bore 3 extends through the body 1 with its upper surface to the surface of the recess 2. Be provided with gas blow pipe 4 in the centre bore 3, the upper end of gas blow pipe 4 is provided with the square sliding head 5 with centre bore 3 matched with, generally sliding head 5 and gas blow pipe 4's upper end flange joint, certainly under the prerequisite of guaranteeing connection stability, adopt other fixed forms such as joint to do. And a vertical air guide hole 6 is formed in the center of the sliding head 5, and the air guide hole 6 is communicated with the upper end of the air blowing pipe 4. The whole air flow channel enters from the upper end of the central hole 3, then enters into the air guide hole 6 on the sliding head 5, then enters into the air blowing pipe 4, and finally is blown out from the lower end of the air blowing pipe 4.

Generally, compared with the traditional blowing head, the biggest difference of the invention is that the sliding head 5 and the blowing pipe 4 can be integrally lifted in the central hole 3, so that the extending length of the lower end of the blowing pipe 4 is changed, and the length of the blowing pipe extending into the glass bottle can be changed, and the glass bottle blowing head is suitable for the production of glass bottles with different heights.

As shown in fig. 1, it can be seen that the sliding head 5 in the central hole 3 of the present invention plays a role of limiting and guiding on one hand and communicating the upper end of the central hole 3 with the blowing pipe 4 on the other hand, and a certain airtight fit should be provided between the sliding head 5 and the central hole 3 on the third hand, that is, when blowing is performed, pressurized gas is not blown out through the gap between the central hole 3 and the sliding head 5, so as to avoid affecting the blowing pressure. For this reason, as shown in fig. 4, it is further preferable that the air vent 6 of the sliding head 5 is funnel-shaped, an annular air cavity 20 is disposed inside the sliding head 5 around the air vent 6, a side hole 21 is disposed on a side wall of an upper section of the air vent 6, and the air cavity 20 is communicated with the air vent 6 through the side hole 21. An annular expansion opening 22 is formed in the outer side wall of the sliding head 5, and a matched elastic expansion film is arranged in the expansion opening 22. During blowing, a part of pressurized air enters the air cavity 20 through the side hole 21, and the pressure in the air cavity 20 is increased, so that an elastic expansion film in the expansion port 22 is tightly attached to the side wall of the central hole 3, and sealing is realized, wherein the elastic expansion film is usually a silicone film, a rubber film and the like. When the air blowing is not performed, the pressure in the air cavity 20 is lower, the elastic expansion film retracts, the friction force between the hole wall of the central hole 3 and the sliding head 5 cannot be increased, and the smooth sliding is ensured.

How to drive the air blowing pipe 4 is shown in fig. 1 and 2, the body 1 of the invention is composed of an upper half section 7 and a lower half section 8, and the upper half section 7 and the lower half section 8 are connected through short rods 0 which are uniformly distributed in a ring shape around the central hole 3. A driving mechanism is arranged in the area between the upper half section 7 and the lower half section 8, and the air blowing pipe 4 can move in the central hole 3 along the up-and-down direction under the driving of the driving mechanism.

The driving mechanism comprises a gear disc 9 which is arranged between the upper half section 7 and the lower half section 8 in an overhead mode and can rotate, and the blowing pipe 4 is driven to lift up and down through the rotation of the gear disc 9. In order to ensure the stability of the installation of the gear plate 9 and the smoothness of the rotation, the present invention may be better that, as shown in fig. 2, an upper clamping ring 13 and a lower clamping ring 14 are respectively arranged on the upper surface and the lower surface of the gear plate 9, and each of the upper clamping ring 13 and the lower clamping ring 14 includes a ring body 15 and an annular wing plate 16 arranged on one end peripheral surface of the ring body 15. The gear plate 9 is clamped between wing plates 16 of the upper clamping ring 13 and the lower clamping ring 14 and is locked through a clamping bolt 17 to form flange-like connection.

The design of the upper clamping ring 13 and the lower clamping ring 14 can greatly improve the stability of the gear disc 9, and is convenient for the connection of the gear disc 9 with the upper half section 7 and the lower half section 8. The bottom of the upper half section 7 and the top of the lower half section 8 are respectively provided with an upper extension 18 and a lower extension 19 at positions opposite to the central hole 3, the upper extension 18 is connected with the ring body 15 of the upper clamping ring 13 through an upper bearing, and the lower extension 19 is connected with the ring body 15 of the lower clamping ring 14 through a lower bearing.

A vertical threaded hole 10 is formed in the center of the gear disc 9, and the threaded hole 10 is sleeved outside the air blowing pipe 4 and is in threaded fit with the air blowing pipe 4. In the rotating process of the gear plate 9, the upper end of the blowing pipe 4 is subjected to the limiting and guiding action of the sliding head 5, so that the blowing pipe 4 can be driven to move up and down. As for how to drive the gear disc 9 to rotate, a driving motor 11 is arranged on one side wall of the upper half section 7, the output end of the driving motor 11 faces downwards, a driving gear 12 is arranged at the end part of the driving motor 11, and the driving gear 12 is meshed with the gear disc 9.

The upper end of the upper half section 7 of the body 1 is used for being connected with a pressurized air source, and in order to ensure the stability of the connection between the upper half section 7 and the air source connector, a connecting flange is arranged on the circumferential surface of the upper end of the upper half section 7, and the connecting flange is a protruded annular edge on the circumferential surface of the upper end of the upper half section 7 in the figure 1 and is connected with the air source connector flange. The upper end of the central hole 3 is provided with a circular recess hole 31 for inserting the end of the supply connection to form a more stable fixation.

In addition, compared with the traditional blowing head, the blowing head has the second great difference that the temperature of the pressurized air can be changed according to the blowing requirement, so that the problem that the blank is cooled too fast due to the lower temperature of the pressurized air and the plasticity of the blank is influenced in the process of vertical operation of a thicker glass bottle is solved. Therefore, the heating mechanism is further integrated on the air blowing pipe 4, as shown in fig. 1, 2 and 5, a driving sleeve 23 is further sleeved outside the middle section of the air blowing pipe 4, the driving sleeve 23 is fixedly connected with an air blowing pipe 24, as shown in fig. 2 and 5, a supporting edge 28 is arranged on a section of the air blowing pipe 4 opposite to the lower end of the driving sleeve 23, and the lower end of the driving sleeve 23 is supported on the supporting edge 28 and is locked with the supporting edge 28 through a connecting bolt 29.

The outer circumferential surface of the driving sleeve 23 is provided with external threads. The air blow pipe 4 and the gear plate 9 are arranged in the threaded hole 10 in a penetrating manner through the driving sleeve 23 to form threaded fit. That is, when the blowing pipe 4 is driven, the gear plate 9 of the present invention essentially drives the driving sleeve 23 fixed thereon to move up and down, and the driving sleeve 23 drives the blowing pipe 4 to move up and down. An induction coil 24 is further arranged in the driving sleeve 23, and the induction coil 24 is sleeved outside the air blowing pipe 4. When heating is needed, the induction coil 24 is electrified, eddy current is generated inside the metallic air blowing pipe 4, a large amount of heat is generated, the air flows through the air blowing pipe 4, heat exchange with the air blowing pipe 4 is realized, and the condition that the temperature of the blown pressurized air flow is not too low is ensured.

Of course, since the induction coil 24 is installed on the blowing pipe 4, and the blowing pipe 4 needs to move up and down, in order to ensure the stability of the electrical connection, two conductive sliding shoes 25 are disposed on two sides of the upper end of the driving sleeve 23, and the two conductive sliding shoes 25 are electrically connected with two terminals of the induction coil 24, respectively. Two vertical conducting strips 26 are embedded on two side walls of the central hole 3 of the upper half section 7, and the conducting strips 26 are opposite to the conducting sliding shoes 25. The conducting strips 26 are connected to terminals 27 on the side walls of the upper half 7 by connecting wires.
