Description

Technical Field

[0001] This utility model belongs to the field of glass production, and specifically relates to a cleaning device for the inner surface of a pharmaceutical glass tube. Background Technology

[0002] Pharmaceutical glass tubing is a key raw material for pharmaceutical glass bottle packaging materials, especially for packaging materials used directly in injectable drug vials, which are directly related to people's lives and health. During the manufacturing process, pharmaceutical glass tubing is formed from molten high-temperature glass through blowing and cooling to create a glass tube of a certain diameter. Air bubbles, stones, scratches, and other impurities within the tube, as well as dust and oil stains adhering to the inner wall during packaging and storage, all directly affect product quality. In particular, if the inner wall of the glass tubing is not clean during the firing of pharmaceutical glass vials (ampoules or vials), it can easily become an impurity in the glass bottle, potentially seeping into the medication and endangering lives. Therefore, the cleanliness of the inner surface of pharmaceutical glass tubing is a crucial and strictly controlled aspect.

[0003] Pharmaceutical manufacturers typically clean glass bottles before filling them with chemicals. However, glass tubes are rarely cleaned during the bottle manufacturing process. As a result, impurities from the glass tubes are fused into the bottles during firing, and are subsequently detected and discarded during quality inspection. This leads to the waste of some glass tubes or bottles, affecting the yield rate, reducing production efficiency, and wasting resources. Therefore, it is essential to adjust the process and clean the glass tubes before manufacturing the bottles. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a cleaning device for the inner surface of pharmaceutical glass tubes. By cleaning the glass tubes before they are loaded onto the machine, the device removes any adhering substances from the inner surface of the glass tubes, thereby improving product quality and reducing the defect rate during the glass bottle manufacturing process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cleaning device for the inner surface of a pharmaceutical glass tube includes a rigid central tube that matches the inner diameter of the glass tube. One end of the central tube is open as a water inlet for connecting to a water supply mechanism. The other end of the central tube is closed. Multiple sets of water outlets are distributed axially on the wall of the central tube.

[0007] Multiple cleaning mechanisms are arranged along the axial direction on the central tube, and the cleaning mechanisms are located near the water outlet group; each cleaning mechanism includes a cylindrical pipe clamp body, which is detachably fixed on the central tube, and a cleaning component is provided on the outer circumference of the cylindrical pipe clamp body.

[0008] Furthermore, the cleaning mechanism corresponds one-to-one with the water outlet group.

[0009] Furthermore, each water outlet group includes multiple water outlets, which are axially positioned on the central tube and are evenly arranged radially along the circumference of the central tube.

[0010] Furthermore, each group of water outlets includes three water outlets, with an angle of 120° between every two water outlets.

[0011] Furthermore, the cylindrical pipe clamp body is composed of two semi-cylindrical pipe clamps, which are connected and clamped to the central pipe by a fastener.

[0012] Furthermore, in the two semi-cylindrical pipe clamps, one semi-cylindrical pipe clamp has a connecting through hole at a corresponding position, and the other semi-cylindrical pipe clamp has a threaded through hole at a corresponding position; the fastener is a connecting bolt, which passes through the connecting through hole and is threadedly connected to the threaded through hole, thereby fixing the two semi-cylindrical pipe clamps together.

[0013] Furthermore, multiple sets of the cleaning components are arranged in the axial direction of the cylindrical pipe clamp body. Each set of cleaning components includes multiple flexible filaments, which are evenly arranged in a ring along the cylindrical pipe clamp body.

[0014] Furthermore, the cylindrical tube clamp body has multiple fixing holes distributed on it, and each fixing hole corresponds to a flexible wire; the root of the flexible wire is bonded and fixed in the corresponding fixing hole.

[0015] Furthermore, the outer diameter of the central tube is one-third to two-thirds of the inner diameter of the glass tube.

[0016] Furthermore, the central tube is made of stainless steel, and the cylindrical tube clamp body is made of rigid plastic.

[0017] The beneficial effects of this utility model are:

[0018] By applying this utility model, the glass tubes are cleaned before being put into the machine, which can overcome the problem that the unclean inner wall of the glass tubes is likely to become an impurity in the glass bottle when the glass tubes are fired into pharmaceutical glass bottles (ampoules or vials). This reduces or lowers the probability of glass bottles containing impurities being discarded after the glass tubes are made into bottles, improves the yield rate, and reduces resource waste.

[0019] This invention combines a central tube with a cleaning mechanism. During glass tube cleaning, the central tube rotates or moves axially under external force, driving the flexible wires to move. Simultaneously, with the assistance of water outlet, the inner surface of the glass tube is cleaned, thereby removing adhering substances, improving the appearance quality of the glass tube, enhancing product quality, and reducing the defect rate during glass bottle manufacturing. Furthermore, this device is simple, convenient, and quick to install and disassemble. Attached Figure Description

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1 to 4 As shown, this embodiment provides a cleaning device for the inner surface of a pharmaceutical glass tube, including a rigid central tube 1 that matches the inner diameter of the glass tube. Generally, the outer diameter of the central tube 1 is one-third to two-thirds of the inner diameter of the glass tube.

[0027] The central pipe 1 is made of stainless steel. One end of the central pipe 1 is open as a water inlet 3, which is used to connect to the water supply mechanism; the other end of the central pipe 1 is closed. At the same time, multiple sets of water outlet holes are distributed axially on the pipe wall of the central pipe 1.

[0028] Each water outlet group includes three water outlets 2. The three water outlets 2 are axially positioned on the central tube and are evenly arranged radially along the circumference of the central tube 1. That is, the angle between every two water outlets is 120° to reduce the impact on the rigidity of the central tube 1.

[0029] The central tube 1, through the above-mentioned configuration and its cooperation with the water outlet 2, is used for water lubrication, rinsing and cleaning during cleaning.

[0030] Multiple cleaning mechanisms are arranged along the axial direction on the central tube 1. Each cleaning mechanism corresponds to a group of water outlets and is located near the group of water outlets. The cleaning mechanism works with the water outlets 2 to clean dust and other impurities inside the glass tube.

[0031] Each cleaning mechanism includes a cylindrical pipe clamp body, which is detachably fixed to the central pipe 1, and a cleaning component is provided on the outer circumference of the cylindrical pipe clamp body.

[0032] In this embodiment, the cylindrical pipe clamp body is composed of a left semi-cylindrical pipe clamp 4 and a right semi-cylindrical pipe clamp 5. The left semi-cylindrical pipe clamp 4 and the right semi-cylindrical pipe clamp 5 are connected and clamped to the central pipe 1 by connecting bolts 8. Both the left semi-cylindrical pipe clamp 4 and the right semi-cylindrical pipe clamp 5 are made of rigid plastic.

[0033] The left semi-cylindrical pipe clamp 4 has a connecting through hole at the corresponding position, and the right semi-cylindrical pipe clamp 5 has a threaded through hole 7 at the corresponding position; the connecting bolt 8 passes through the connecting through hole and is threadedly connected to the threaded through hole 7, thus fixing the left semi-cylindrical pipe clamp 4 and the right semi-cylindrical pipe clamp 5 together.

[0034] In this embodiment, multiple sets of cleaning components are arranged in the axial direction of the cylindrical pipe clamp body. Each set of cleaning components includes multiple flexible filaments 6, which are evenly arranged in a ring along the cylindrical pipe clamp body.

[0035] To facilitate the installation of the flexible wire strip 6, multiple fixing holes are distributed on the cylindrical pipe clamp body. Each fixing hole corresponds to a flexible wire strip, and the root of the flexible wire strip 6 is bonded and fixed in the corresponding fixing hole.

[0036] In use, this invention first connects the left semi-cylindrical pipe clamp 4 and the right semi-cylindrical pipe clamp 5, each with a flexible threaded strip 6, ensuring they are on the same horizontal plane. Then, the connecting bolt 8 is screwed into the threaded through hole 7 and tightened, clamping and fixing it to the central tube 1 as a single unit. Through external force (such as a handheld or electric / hydraulic motion mechanism), the rotation and axial movement drive the flexible threaded strip 6, simultaneously cleaning the inner surface of the glass tube with the assistance of water outlet 2, thereby removing any adhering substances from the inner surface of the glass tube.

[0037] When the device needs to be removed, simply loosen the connecting bolt 8 to disassemble and remove the left semi-cylindrical pipe clamp 4 and the right semi-cylindrical pipe clamp 5. Installation and disassembly are both relatively convenient.
