[0002] Glass tubes are the basic material for manufacturing glass containers. Glass bottles and other glass containers are packaging containers for many medicines. Due to the requirements of drug quality control, the performance and quality of glass containers are also highly required. Glass products are widely used in the pharmaceutical packaging industry due to their excellent properties such as high chemical stability, high thermal shock resistance and low linear thermal expansion coefficient.

[0003] According to the Chinese patent publication number: CN210855798U, a glass tube forming device includes a main shaft with a hollow configuration, a refractory end head fixedly connected to one end of the main shaft, a pressure ring slidably mounted on the main shaft and away from the refractory end head, and a rotating tube mounted on the main shaft and located between the refractory end head and the pressure ring, the refractory end head having a clamping portion facing the other end of the main shaft, the clamping portion of the refractory end head clamps the tube wall of one end of the rotating tube, and the pressure ring presses the other end of the rotating tube.

[0004] In the above scheme, the glass tube is solidified and formed inside the through hole, which still has the following disadvantages: the diameter inside the through hole is fixed, so only glass tubes with fixed diameters can be produced, which may not meet the current demand for glass tube diversity. Utility Model Content

[0005] The utility model aims to provide a glass tube production and forming device to solve the problem that only glass tubes with fixed diameters can be produced and the current demand for glass tube diversity may not be met.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a glass tube production and molding equipment, including a feed box, a molding tube is detachably provided on one side of the feed box, a replacement column is detachably provided inside the molding tube, a fixing ring is provided inside the molding tube, two fixing columns are fixed on the inner wall surface of the molding tube, one end of the fixing column is fixed to the surface of the fixing ring, a filling ring is threadedly connected to the inner surface of the fixing ring, the filling ring is threadedly connected to the replacement column, a feed hole is provided on the top surface of the feed box, an extrusion hole is provided on one side of the feed box, and an air inlet hole is provided on one side of the feed box.

[0007] Preferably, two connecting plates are fixed to the surface of the forming tube close to one end of the feed box, and a plurality of positioning plates are fixed to one side of the feed box, wherein two of the positioning plates form a group, and a flip plate is rotatably arranged between each group of positioning plates.

[0008] Preferably, a sealing ring is fixed to one end of the forming tube close to the feed box, and a storage groove is provided on one side of the feed box, and the storage groove is interference fit with the sealing ring.

[0009] Preferably, a sealing cover is rotatably provided on the top surface of the feed box, a flip plate is fixed on the surface of the sealing cover, a fixed bent rod is fixed on the top surface of the feed box, the fixed bent rod is rotatably inserted with the flip plate, and a handle is fixed on the top surface of the sealing cover.

[0010] Preferably, a connecting pipe is detachably inserted into the interior of the air inlet, and a flange is fixed on the surface of the connecting pipe.

[0011] Preferably, a cooling box is fixed to the bottom of the forming tube, and two adding holes are opened on the top surface of the cooling box.

[0012] Compared with the prior art, a glass tube production and molding device using the above technical solution has the following beneficial effects:

[0013] 1. The staff will first fill the softened raw materials for making glass into the feed box through the feed hole, and then use the air inlet hole to inject gas into the feed box. Under the pressure of the gas, the softened glass raw materials will enter the interior of the forming tube through the extrusion hole. When it is necessary to make glass tubes with different inner diameters, the staff can replace replacement columns with different diameters. When replacing, the staff will first unscrew the replacement column from the inside of the filling ring, and then screw filling rings of different numbers and diameters into the inside of the fixed ring, and then match the replacement column with the corresponding diameter, so that the inner diameter of the finished glass tube can be adjusted according to needs, which increases the diversity of glass tube production;

[0014] Second, before replacing the replacement column with a different diameter, the staff will first turn the flip plate to separate the flip plate from the surface of the connecting plate, so that the feed box and the forming tube can be separated. After replacing the replacement column, the forming tube will be re-attached to one side of the feed box, and the sealing ring will be pressed into the inside of the storage tank, which increases the sealing between the forming tube and the feed box;

[0015] 3. When producing the glass tube, the staff will inject gas into the feed box through the connecting pipe. At this time, the sealing cover is flipped and buckled on the top surface of the feed box, and the sealed feed hole is blocked. The gas entering the feed box can be used to squeeze the glass raw materials into the molding tube. When the glass raw materials move inside the molding tube, the heat of the glass raw materials will be absorbed by the cooling box, which can accelerate the solidification speed of the glass raw materials inside the molding tube.
