Description

Technical Field

[0001] This invention relates to the field of glass product processing technology, specifically to a cleaning device for processing glass tubes. Background Technology

[0002] Glass tubes, as a common industrial raw material, are widely used in chemical, pharmaceutical, lighting, and electronics industries. During the processing of glass tubes, glass powder, oil, or impurities often adhere to the surface of the tubes after cutting, grinding, or heat treatment. Therefore, the cleaning process is a key step in ensuring product quality. In existing technologies, cleaning glass tubes typically employs a conveyor belt combined with a spray system. However, existing cleaning devices lack a targeted fixing structure in practical use. Overly tight fixing can easily lead to tube breakage, while loose fixing can cause rolling or slipping during transport, resulting in impact damage. Furthermore, it's difficult to ensure consistent tube posture during cleaning, affecting the cleaning coverage. In addition, traditional spray systems often use direct spraying from nozzles, resulting in concentrated water flow. While this provides strong impact, the coverage area is limited, easily creating cleaning dead zones. Simultaneously, gas can easily accumulate in the pipes, causing poor water spraying or water flow pulsations, affecting the uniformity of cleaning. Additionally, due to the smooth surface and tubular structure of glass tubes, water droplets easily adhere to the tube walls or openings. Existing drying devices often use static hot air blowing, which fails to break the surface tension of water droplets, resulting in slow drying speeds and water stains left on the tube surface after drying, affecting subsequent processing or the appearance quality of the finished product.

[0003] Therefore, there is a need for a cleaning device for glass tube processing that can securely clamp, spray from all directions, and efficiently remove surface water droplets. Summary of the Invention

[0011] Preferably, the drying box includes a lower box and an upper box, the hot air supply pipe is connected to the upper box, and the air distribution plate is located in the lower box; The gas distribution plate includes: a mesh frame, a foot base, and a side mesh frame; a mesh plate is provided on the inner side of the mesh frame, and the mesh plate is located directly below the hot gas supply pipe; the foot base is located on the inner wall circumferentially of the lower housing; one end of the side mesh frame is hinged to the foot base, and the other end is elastically connected to the mesh frame through a first spring, and a side mesh plate is provided on the inner side of the side mesh frame; a gap hole is formed between two adjacent side mesh frames.

[0012] Preferably, the air distribution plate further includes a lower support provided at the bottom of the lower housing, and the middle part of the mesh frame is elastically connected to the lower support through an elastic support member.

[0014] The beneficial effects of the present invention are as follows: By using the cleaning device for glass tube processing provided by the present invention, the following technical effects are achieved: 1. This invention features a column with flexible rubber arms on the conveyor belt, which can not only adapt to glass tubes of different specifications (sleeved or seated), but also flexibly clamp the tubes through flexible deformation, effectively preventing glass breakage caused by rigid contact; furthermore, the column is connected to the rigid disc through the flexible rubber column, so that the glass tubes can shake when subjected to spray impact or drying airflow, which, together with the airflow disturbance in the drying section, can effectively shake off water droplets adhering to the surface of the tubes, preventing water stains from remaining, and significantly improving the efficiency of cleaning and drying.

Simultaneously, the vibration of the wire mesh rack drives the side mesh rack to swing through the first spring, causing the opening and closing size of the gap holes to change dynamically, further enhancing the airflow disturbance capability. This dual effect of airflow combined with vibration, along with the shaking of the glass tube itself, can quickly break the surface tension of the water film on the glass surface, accelerating water removal and solving the problems of difficult drying and easy water stains on glass tubes in the prior art.

[0019] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation schemes as long as the effects of the present invention can be achieved.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] This embodiment discloses a cleaning device for processing glass tubes. The cleaning device includes a conveyor belt 2 that is rolled on a frame 1. The conveyor belt 2 has a feeding section 6, a spraying section 5, a drying section 4 and a discharging section 3 formed sequentially on it.

[0023] The conveyor belt 2 is provided with several rows of equally spaced columns 23. A clamping groove 25 is formed between four adjacent rectangular columns 23. The glass tube is sleeved on the column 23 or sits in the clamping groove 25.

[0024] The outer wall of the column 23 is provided with multiple flexible rubber arms 24 at equal intervals in the top view projection, and the ends of the rubber arms 24 can be bent.

[0025] The column 23 and clamping groove 25 provide two different placement methods. One is that it can be sleeved on the column 23 and fixed to the inner wall of the glass tube by the flexible rubber arm 24. The other is that it can be placed in the clamping groove 25 and fixed to the outer wall of the glass tube by the circumferential flexible rubber arm 24. It can also adapt to glass tubes of different specifications or shapes (such as tubular tubes can be sleeved, and irregular or short tubes can be seated), which improves the versatility of the device. The flexible rubber arm 24 can generate adaptive deformation when the glass tube is placed, which not only plays the role of clamping and fixing to prevent slippage during transportation, but also acts as a flexible buffer layer to prevent the glass tube from being damaged by rigid collision.

[0026] In this embodiment, a rigid disk 27 corresponding to the column 23 is provided on the conveyor belt 2. The root of the column 23 is connected to the rigid disk 27 through a flexible rubber column 28. An abutment 26 is formed at the outer edge of the bottom of the column 23. When the flexible rubber column 28 bends, the abutment 26 abuts against the rigid disk 27. The rigid disk 27 provides a stable mounting base, while the flexible rubber column 28 gives the column 23 a multi-degree-of-freedom swing capability. Specifically, during the cleaning and drying process, when the glass tube is subjected to external force (such as water flow impact or airflow impact), the flexible rubber column 28 bends, causing the glass tube to shake, which helps to shake off the water droplets adhering to the inner and outer walls of the tube, improving the cleaning and drying efficiency. The abutment 26 is provided to limit the maximum bending amplitude of the flexible rubber column 28, preventing excessive bending from causing the glass tube to tip over or interfere with adjacent workpieces, and ensuring stability during the shaking process.

[0027] A spray frame 7, which is fixed to the frame 1, is installed at the spray section 5. The spray frame 7 sprays water onto the glass tubes conveyed on the conveyor belt 2.

[0028] The spray frame 7 in this embodiment includes a liquid supply pump 71, a main pipe 72, several branch pipes 73, a defoamer 74, a nozzle 75, and multiple baffles 76. Specifically, the liquid supply pump 71 is fixed on the frame 1; the main pipe 72 is connected to the liquid supply pump 71; the branch pipes 73 are arranged horizontally above the conveyor belt 2, and each branch pipe 73 is connected to the main pipe 72, and the nozzles 75 are arranged on the branch pipes 73; the liquid supply pump 71 provides a power source to pressurize and deliver the cleaning liquid to the main pipe 72, and distribute it to each branch pipe 73, and finally spray it out through the nozzles 75 to realize automated continuous cleaning of the workpiece; the design of multiple branch pipes 73 ensures the breadth of spray coverage.

[0029] Furthermore, the defoamer 74 is located at the end of the branch pipe 73 close to the main pipe 72 to discharge the gas entering the branch pipe 73. During the liquid transportation process, gas may accumulate in the pipe to form gas clouds, which may cause the nozzle 75 to spray water poorly or produce pulsed spray, affecting the uniformity of cleaning. The defoamer 74 can automatically discharge the gas in the pipe to ensure that the branch pipe 73 is full of cleaning liquid and ensure that the water flow sprayed from the nozzle 75 is stable and continuous.

[0030] It also includes multiple baffles 76, which are fixed on the frame 1 and are set in correspondence with each pipe 73, and are located below the nozzle 75.

[0031] The main pipe 72 has a horizontal section 77 and an inclined section 78, and a baffle plate 76 is disposed at the horizontal section 77. In this embodiment, the baffle plate 76 includes a fixed plate 761, a strip-shaped slot 763, an adjusting plate 764, and an inclined plate 765. The fixed plate 761 is fixedly connected to the frame 1. The strip-shaped slot 763 is vertically opened on the fixed plate 761. The adjusting plate 764 is connected to the fixed plate 761 after passing through the slot 763 by a fixing bolt 762. The inclined plate 765 is disposed below the adjusting plate 764.

[0032] For example, the water jet sprayed from the nozzle 75 is a concentrated jet. If it directly impacts the glass tube, it can easily cause excessive local stress or limit the cleaning area. In this embodiment, the baffle plate 76 is set below the nozzle 75, and the inclined plate 765 is used to receive the water flow and disperse it into splashing water droplets, which significantly expands the spray coverage area and eliminates cleaning dead corners. In addition, by moving the fixing bolt 762 in the strip slot 763, the height position of the adjusting plate 764 and the inclined plate 765 can be adjusted, thereby changing the distance and angle at which the jet from the nozzle 75 hits the inclined plate 765. The shape of the splashing water droplets can be adjusted according to the size of the glass tube to achieve the best cleaning effect.

[0033] In this embodiment, a drying box 8 is provided at the drying section 4. A hot air supply pipe 11 is connected to the drying box 8. A gas equalization plate is provided inside the drying box 8. The gas equalization plate evenly distributes the gas flowing out of the hot air supply pipe 11 onto the conveyor belt 2.

[0034] The drying chamber 8 includes a lower chamber 9 and an upper chamber 10. The hot air supply pipe 11 is connected to the upper chamber 10, and the air distribution plate is located inside the lower chamber 9 to evenly distribute the gas flowing out of the hot air supply pipe 11 onto the conveyor belt 2.

[0035] The gas distribution plate includes a mesh frame 20, a foot 12, and a side mesh frame 13; a mesh plate 21 is provided on the inner side of the mesh frame 20, and the mesh plate 21 is located directly below the hot air supply pipe 11; the foot 12 is located on the inner wall circumferentially of the lower housing 9; one end of the side mesh frame 13 is hinged to the foot 12, and the other end is elastically connected to the mesh frame 20 through a first spring 15; a side mesh plate 14 is provided on the inner side of the side mesh frame 13; a gap hole 22 is formed between two adjacent side mesh frames 13.

[0036] In actual operation, the mesh plate 21 initially buffers and disperses the high-speed hot airflow ejected from the hot air supply pipe 11, achieving downward drying in the vertical direction (first direction); the circumferentially arranged side mesh plate 14 guides the hot airflow that diffuses to the edge of the chamber to the oblique downward direction (second direction), forming a drying effect on the side wall of the glass tube; this multi-directional air distribution structure ensures that the surfaces of the glass tube are heated evenly, avoiding overheating or blind spots on one side; the gap hole 22 serves as an auxiliary airflow channel to further optimize the airflow distribution.

[0037] The gas distribution plate also includes a lower support 16 located at the bottom of the lower housing 9. The middle part of the mesh rack 20 is elastically connected to the lower support 16 via an elastic support member. The elastic support member includes a bottom cylinder 17 fixedly connected to the lower support 16 and a retaining rod 19 fixedly connected to the mesh rack 20. The bottom of the retaining rod 19 is inserted into the bottom cylinder 17, and the end of the retaining rod 19 inserted into the bottom cylinder 17 is connected to the bottom of the inner cavity of the bottom cylinder 17 via a second spring 18. When the high-pressure hot airflow ejected from the hot air supply pipe 11 impacts the mesh rack 21, the resulting impact force will compress the second spring 18, causing the mesh rack 20 to move downward. When the airflow pressure fluctuates or the mesh rack 20 is in a certain position, the mesh rack 20 will move downward. When the first spring 15 and the second spring 18 rebound together, the wire mesh frame 20 moves upward; this reciprocating motion causes the wire mesh frame 20 to vibrate at a high frequency; when the wire mesh frame 20 vibrates and descends, the first spring 15 pulls the side wire mesh frame 13 to rotate around the foot seat 12, causing the adjacent side wire mesh frames 13 to open and the gap hole 22 to become larger; when the wire mesh frame 20 rises, the side wire mesh frames 13 return to their original position; this dynamic opening and closing action changes the cross-sectional area of ​​the airflow channel, causing the drying airflow to produce a pulsed blowing effect; the pulsed airflow, combined with the flexible swing characteristics of the column 23, can effectively shake off the water film adhering to the surface of the glass tube, significantly improving the drying efficiency.

[0038] Working principle: At the feeding section 6 of conveyor belt 2, the operator places the glass tube onto the column 23 or into the clamping groove 25. The flexible rubber arm 24 wraps around and protects the glass tube. As the conveyor belt 2 rotates, the glass tube first flows to the spray section 5. The liquid supply pump 71 draws water from the water source into the main pipe 72, and then distributes it to each branch pipe 73. When entering the branch pipe 73, the defoamer 74 eliminates the gas in the liquid, and the water is sprayed out through the nozzles 75 on the branch pipe 73. The adjusting plate 764 can be adjusted up and down through the design of the fixing bolts 762 and the slot 763. The water sprayed from the nozzles 75 acts on the inclined plate 765 of the baffle plate 76 and is dispersed into splashing water, covering and cleaning the glass tube over a large area. During this process, the impact force of the water flow causes the column 23 to shake slightly through the flexible rubber column 28, which helps to remove dirt. After cleaning, the glass tubes move to the drying section 4 along the conveyor belt 2. Hot air supplied by the hot air inlet pipe 11 fills the drying chamber 8 and acts on the wire mesh plate 21. The airflow first sprays downwards through the wire mesh plate 21 in a first direction, acting on the glass tubes. Additionally, the airflow flows circumferentially within the drying chamber 8, acting on the side wire mesh plate 14. At this time, the airflow is obliquely sprayed out from the side wire mesh plate 14 in a second direction, acting on the glass tubes. The stable spraying of the two airflows creates stable drying for the glass tubes. Because the airflow is vertically sprayed out through the hot air inlet pipe 11 and acts on the wire mesh plate 21, the impact of the airflow on the wire mesh frame 20 drives the clamping rod 19 to repeatedly press the second spring 18, causing the wire mesh frame 20 to vibrate continuously. As the mesh frame 20 vibrates and descends, it causes each side mesh frame 13 to gradually separate, forming gap holes 22. At this time, the airflow flows out through the gap holes 22 and impacts the glass tube. The glass tube shakes on the column 23, causing the oblique airflow blown out by the side mesh plate 14 and the airflow flowing out of the gap holes 22 to exhibit dynamic changes. This dynamic airflow impacts the glass tube, forcing the flexibly connected column 23 to drive the glass tube to shake and oscillate irregularly. The shaking of the glass tube breaks the surface tension of the water droplets, allowing the water to quickly detach from the surface of the tube. Combined with the uniform hot airflow, this achieves rapid and thorough drying. Finally, the dried and clean glass tube moves with the conveyor belt 2 to the discharge section 3, where it is removed manually or by a robotic arm, completing the entire processing flow.
