[0002] Currently, the glass bottle forming process in the glass bottle manufacturing industry is mainly divided into two stages: the primary blank forming stage and the finished product forming stage.

[0003] The existing patent publication number "CN104140193A" discloses a preliminary mold with a cavity inside. A funnel-shaped feeding cavity is formed at the upper opening of the preliminary mold and is connected to the cavity. The lower part of the preliminary mold is a bottle forming part, and the cavity is set inside the bottle forming part. The upper part of the preliminary mold is a feeding part, and the feeding cavity is set inside the feeding part. The bottle forming part and the feeding part are integrally formed, and the bottom of the feeding cavity is connected to the top of the cavity.

[0004] The above description has the following problems: When the high-temperature molten glass enters the mold cavity through the feeding chamber, the heat of the molten glass is conducted into the feeding chamber. After long-term operation, the inner wall of the feeding chamber is easily damaged. After damage, the molten glass tends to stick to the inner wall, affecting the feeding process. Moreover, this feeding chamber is an independent feeding chamber, and it is complicated and inconvenient to replace it after damage. In addition, the diameter and shape of this feeding chamber are limited and cannot meet the actual working requirements for different diameters and shapes of feeding chambers. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding funnel for the initial mold of glass bottle processing, which solves the problems of existing feeding chambers being independent, complicated and inconvenient to replace after damage, and having a single diameter and shape, which cannot meet the actual work requirements for different diameters and shapes of feeding chambers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a feeding funnel for a preliminary mold of a glass bottle, including a funnel body and an inner liner embedded inside the funnel body. The inner liner is detachably connected to the funnel body. The longitudinal height of the funnel body is greater than the longitudinal height of the inner liner. A liquid guiding channel is provided in the inner liner, which communicates with the upper opening of the funnel body. The liquid guiding channel is arranged in a funnel shape with a larger upper part and a smaller lower part. The diameter of the liquid outlet of the liquid guiding channel is equal to or smaller than the diameter of the lower opening of the funnel body.

[0008] Furthermore, the inner wall of the liquid guiding channel is coated with a graphite coating.

[0009] Furthermore, a plurality of fastening bolts are provided along the circumference on the outer edge surface of the funnel body, and a threaded blind hole that mates with the fastening bolts is provided on the outer edge surface of the inner liner. The main body of the fastening bolt passes through the funnel body and is threadedly connected to the threaded blind hole.

[0010] Furthermore, the liner includes an upper part and a lower part, the outer diameter of the upper part is larger than the outer diameter of the lower part, and the inner wall of the funnel body is provided with a limiting boss for supporting the upper part along its circumference.

[0011] Furthermore, the outer diameter of the lower part gradually decreases from top to bottom along its axial direction, and the shape of the position corresponding to the lower part inside the funnel body is adapted to the lower part.

[0012] Furthermore, the lower opening of the funnel body is provided with a supporting protrusion along its circumference for supporting the inner substrate.

[0013] Furthermore, at least one anti-mistake protrusion is provided on the supporting protrusion along its circumference, and an anti-mistake step surface that cooperates with the anti-mistake protrusion is provided on the inner lining at a position corresponding to the anti-mistake protrusion.

[0014] Furthermore, the opening diameter of the funnel body located above the liner gradually increases from bottom to top, and the inlet of the liquid guiding channel has the same minimum diameter as the opening on the funnel body.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] This utility model discloses a feeding funnel for initial mold making of glass bottles, comprising a funnel body and an inner liner embedded inside the funnel body. The inner liner is detachably connected to the funnel body. The longitudinal height of the funnel body is greater than the longitudinal height of the inner liner. A liquid guiding channel is provided in the inner liner, communicating with the upper opening of the funnel body. The liquid guiding channel has a funnel-shaped structure, wider at the top and narrower at the bottom. The diameter of the liquid outlet of the liquid guiding channel is equal to or smaller than the diameter of the lower opening of the funnel body. When the feeding funnel is damaged and needs replacement due to prolonged operation in a high-temperature environment, only the inner liner needs to be replaced, making maintenance convenient, time-saving, and labor-saving. Furthermore, since the inner liner is detachably connected to the funnel body, different shapes and sizes of inner liners can be replaced according to actual working needs, improving the utilization rate of the funnel.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] refer to Figure 1 and Figure 2 The present invention provides a feeding funnel for a glass bottle processing initial mold, comprising a funnel body 1 and a detachable liner 2 embedded inside the funnel body 1. A plurality of fastening bolts 3 are arranged along the circumference on the outer edge surface of the funnel body 1, and a threaded blind hole 4 that mates with the fastening bolts 3 is provided on the outer edge surface of the liner 2. The main body of the fastening bolt 3 passes through the funnel body 1 and is threadedly connected to the threaded blind hole 4.

[0030] refer to Figures 2-5 The longitudinal height of the funnel body 1 is greater than the longitudinal height of the liner 2. The liner 2 has a liquid guiding channel 5 that communicates with the upper opening of the funnel body 1. The liquid guiding channel 5 has a funnel-shaped structure that is wider at the top and narrower at the bottom. The diameter of the outlet of the liquid guiding channel 5 is equal to or smaller than the diameter of the lower opening of the funnel body 1. The shape of the outlet of the liner 2 can be changed according to actual needs; the outlet of the liner 2 can be elliptical, rectangular, or circular. In this application, an elliptical outlet of the liner 2 is used as an example. The shape of the lower opening of the funnel body 1 matches the shape of the outlet of the liner 2, and the diameter of the outlet of the liner 2 is smaller than the diameter of the opening of the funnel body 1.

[0031] refer to Figure 1 and Figure 2 By setting this feeding funnel as a double-layer structure, during operation, the high-temperature glass liquid mainly enters the primary mold through the liquid guiding channel 5 in the inner liner 2. When this feeding funnel works in a high-temperature environment for a long time, the inner liner 2 is also the part that is easily damaged. Since the inner liner 2 is detachably connected to the funnel body 1, when replacing or maintaining it, only the inner liner 2 needs to be replaced, which is convenient, time-saving and labor-saving. In addition, since the inner liner 2 is detachably connected to the funnel body 1, inner liners of different shapes and sizes can be replaced according to actual working needs, thereby improving the utilization rate of the funnel.

[0032] refer to Figure 5 The inner wall of the liquid guiding channel 5 is coated with a graphite coating 6. Based on the characteristic of graphite to form a lubricating layer at high temperature, when the high-temperature glass liquid enters the primary mold from the liquid guiding channel 5 of the liner 2, the high-temperature glass liquid is rapidly flowed into the primary mold by the graphite coating 6 set in the liquid guiding channel 5 at high temperature, thereby reducing the risk of adhesion and the heat loss of the high-temperature glass liquid.

[0033] refer to Figure 5The liner 2 includes an upper part 21 and a lower part 22. The outer diameter of the upper part 21 is larger than that of the lower part 22. A limiting boss 7 for supporting the upper part 21 is provided along the circumference of the inner wall of the funnel body 1. The limiting boss 7 limits the position of the liner 2 embedded in the funnel body 1, so that the liner 2 and the funnel body 1 can better fit together. The outer diameter of the lower part 22 gradually decreases from top to bottom along its axial direction. The shape of the position inside the funnel body 1 corresponding to the lower part 22 is adapted to the lower part 22. This structure allows the outer edge of the liner 2 to fit more tightly against the inner wall of the funnel body 1, and also limits the liner 2 in the longitudinal direction, so that the liner 2 is more firmly and stably installed in the funnel body 1.

[0034] refer to Figure 1 , Figure 5 and Figure 6 The funnel body 1 has a supporting flange 8 along its circumference at its lower opening to support the bottom of the inner liner 2. The supporting flange 8 further supports the inner liner 2 and improves its stability. At least one anti-mistake protrusion 9 is provided along its circumference on the supporting flange 8, and an anti-mistake step surface 10 is provided on the inner liner 2 at a position corresponding to the anti-mistake protrusion 9 to cooperate with the anti-mistake protrusion 9. When the inner liner 2 is installed in the funnel body 1, the cooperation of the anti-mistake protrusion 9 and the anti-mistake step surface 10 allows the inner liner 2 to be installed in the funnel body 1 quickly and accurately, improving installation efficiency and positioning accuracy.

[0035] refer to Figure 5 The opening diameter of the funnel body 1 located above the inner liner 2 gradually increases from bottom to top. The inlet of the liquid guiding channel 5 is the same as the minimum diameter of the opening on the funnel body 1. During the initial glass processing, the funnel body 1 with the structure can better cooperate with the air blowing nozzle in the initial mold device, thereby improving the sealing performance.

[0036] In summary, when the liquid inlet funnel is damaged and needs replacement after working in a high-temperature environment for a long time, only the inner liner 2 needs to be replaced, which is convenient, time-saving and labor-saving. In addition, since the inner liner 2 is detachably connected to the funnel body 1, different shapes and sizes of inner liners 2 can be replaced according to actual working needs, thereby improving the utilization rate of the funnel.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
