Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a sealing structure for the operating window of a dental prosthesis carving machine and the dental prosthesis carving machine. Background Technology

[0002] A dental prosthesis engraving machine is a high-precision CNC device used to manufacture dentures. It can transform a digital dental prosthesis model into a physical form. Using a high-speed rotating milling cutter or drill, it precisely cuts materials such as zirconia, ceramics, resin, and metal alloys to create personalized dentures that match the patient's oral structure. Dental prosthesis engraving machines are characterized by high efficiency, precision, and consistency, significantly improving the efficiency and quality of denture manufacturing. They are widely used in dental clinics and dental prosthesis processing centers.

[0003] The sealing structure of the operating window of the dental prosthesis engraving machine needs to be designed specifically for its miniaturized processing chamber. Compared with traditional industrial equipment, the processing chamber volume of dental prosthesis equipment is significantly reduced (typically less than 1m³). 3 This results in extremely close proximity (typically ≤10cm) between the spindle system, water-cooling module, and protective door. This compact layout presents multiple challenges to preventing water leakage at the door: First, the micro-machining chamber cannot accommodate industrial-grade sealing rings or labyrinth seals. The installation thickness of conventional rubber seals at the door frame must be controlled within 3mm, while thin sealing strips are prone to leakage due to material deformation. At the same time, the close proximity of the water spray block to the door allows the coolant spray pressure (0.2-0.5MPa) to easily create high-pressure penetration at the door gaps. Second, the high-frequency opening and closing of the door (>50 times per day) causes the wear rate of the sealing material to be 3-5 times higher than that of industrial equipment, while the vortex generated by the spindle speed >20,000rpm can cause atomized droplets to escape from gaps as small as 0.1mm.

[0004] The utility model patent with application publication number CN210588382U discloses an isolation structure between the control area and the processing area of ​​a dental prosthesis carving machine, such as... Figure 1 As shown, it includes: a telescopic armor cover 1, the telescopic armor cover 1 having a right-angled cross-section, with both ends fixedly connected to the left and right side walls of the housing 2 respectively, and a mounting groove 4 for a machining spindle 3 provided in the middle, the edge of the mounting groove 4 being fixedly connected to a machining spindle mounting seat 5; an upper sealing plate 6, the left and right ends of the upper sealing plate 6 being fixedly connected to the left and right side walls of the housing 2 respectively, the front end of the upper sealing plate 6 being fixedly connected to the front side wall of the housing 2, and the rear end of the upper sealing plate 6 being movably connected to the front end of the telescopic armor cover 1; and a lower sealing plate 7, the left and right ends of the lower sealing plate 7 being fixedly connected to the left and right side walls of the housing 2 respectively, the bottom of the lower sealing plate 7 being fixedly connected to the bottom of the housing 2, and the top of the lower sealing plate 7 being movably connected to the bottom of the telescopic armor cover 1.

[0005] The structure disclosed in the above-mentioned utility model aims to use the armor telescopic cover in conjunction with the upper and lower sealing plates to divide the shell into a control area and a processing area. It isolates waste and water vapor separately in the processing area, which facilitates the collection of waste and improves the processing environment. Water vapor is discharged directly outside the equipment through the exhaust fan and conveying pipeline, which protects the electrical components and avoids safety hazards such as short circuits. However, it does not achieve a good sealing effect at the operating window.

[0006] This shows that the existing technology still needs to be improved and perfected. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a sealing structure for the operating window of a dental prosthesis carving machine and a dental prosthesis carving machine, so as to solve the problem that the existing dental prosthesis carving machines have poor sealing effect on the operating window of the working cavity.

[0008] The technical solution of this utility model is as follows:

[0009] A sealing structure for the operating window of a dental prosthesis carving machine includes: a window baffle and a first sealing frame, the first sealing frame being rectangular and disposed on the outside of the operating window of the dental prosthesis carving machine; the window baffle being rotatably connected to the body of the dental prosthesis carving machine and being able to cover the first sealing frame.

[0010] The advantages of the above solution are as follows: the side-opening design offers greater flexibility in space utilization, making it particularly suitable for environments with limited operating space, avoiding interference issues caused by insufficient space when using top-and-bottom opening covers; it also allows operators to more easily open and close the window baffle with one hand, providing sufficient space for operations such as tray replacement without being obstructed by top-and-bottom opening covers; furthermore, the side-opening structure is more stable during equipment operation, reducing the risk of accidental opening due to the cover's own weight or vibration. The protruding first sealing frame increases the contact area of ​​the sealing structure, allowing the window baffle to fit more tightly with the first sealing frame when closed, significantly improving sealing performance and effectively preventing leakage of dust, debris, coolant, and lubricant; simultaneously, the protruding first sealing frame acts as a guide, ensuring that the window baffle always moves along a predetermined trajectory during opening and closing, avoiding sealing failure due to offset or misalignment. In addition, when the window baffle is closed, it can completely cover the first sealing frame, forming multiple sealing barriers to effectively prevent external contaminants from entering the processing chamber, while preventing internal cutting waste and liquid from overflowing, ensuring the cleanliness of the processing environment and the stability of equipment operation.

[0011] In a further preferred embodiment, the operation window sealing structure further includes a second sealing frame, which is disposed on the side of the window baffle facing the operation window, and in the closed state, the outer edge of the second sealing frame is attached to the inner edge of the first sealing frame.

[0012] The above solution achieves the following effect: With the cooperation of the first sealing frame and the window baffle, the equipment can effectively isolate external contaminants. However, in demanding applications, a single sealing structure cannot completely prevent the penetration of fine particles or liquids. By setting a second sealing frame on the side of the window baffle facing the operating window, a tighter sealing barrier is formed. This allows the outer edge of the second sealing frame to fit snugly against the inner edge of the first sealing frame, further reducing the sealing gap and ensuring a more stable and reliable seal. This effectively prevents further leakage of dust, debris, and liquids, especially coolant or lubricant generated during processing, avoiding pollution of the external environment caused by leaks. Furthermore, the second sealing frame provides better guidance for the opening and closing of the window baffle, ensuring that the sealing effect is not affected by offset or misalignment, thereby improving the overall protection capability of the equipment.

[0013] In a further preferred embodiment, a water receiving trough is provided under the second sealing frame, and a water-absorbing component is provided in the water receiving trough to prevent liquid splashing.

[0014] The above solution is effective in the following ways: When the operating window baffle is opened, some liquid remains on the second sealing frame. Without a water collection trough, this liquid would drip directly onto the ground, causing a mess and potentially harming equipment or operators. The water collection trough effectively collects this residual liquid, preventing it from directly contacting the ground. Furthermore, the absorbent components within the trough quickly absorb the liquid, preventing it from splashing out due to inertia or external force, thus protecting the cleanliness of the operating area. Simultaneously, the absorbent components improve liquid handling efficiency, ensuring that liquid is promptly treated and prevented from spreading when the window baffle is open, reducing the risk of contamination in the operating area.

[0015] In a further preferred embodiment, the lower end of the first sealing frame is provided with a reflux slope, which is inclined toward the processing cavity to facilitate liquid reflux during wet processing.

[0016] The above solution is effective because during wet machining, coolant flows down the spindle and splashes outwards, sometimes reaching the operating window. Without a suitable liquid guidance design, the splashed coolant can contaminate the operating area and affect the operator's working environment. This invention, by setting a return slope at the lower end of the first sealing frame, effectively guides the coolant back towards the machining chamber, preventing it from lingering at the window or leaking into the external environment. This not only prevents coolant from contaminating the outside of the equipment and the operating area but also ensures smoother coolant flow during machining, avoiding coolant accumulation in the sealing frame and subsequent overflow.

[0017] In a further preferred embodiment, a sealing strip is provided on the outer end face of the first sealing frame, and a guide plate is provided below the sealing strip, with the guide plate inclined toward the processing cavity.

[0018] The advantages of the above solution are as follows: the sealing strip, located on the outer end face of the first sealing frame, allows for a tighter contact with the window sealing surface when the window baffle is closed, further enhancing waterproof and dustproof performance and preventing external contaminants or coolant from entering the equipment. Simultaneously, the sealing strip can adapt to minor displacements caused by temperature changes or equipment vibration during operation, maintaining a good seal and preventing coolant leakage through tiny gaps. The guide plate optimizes the coolant flow path. During wet machining, coolant flows from the spindle and splashes into the operating window area. The guide plate's inclined design towards the machining cavity effectively guides the coolant along the guide plate towards the machining cavity, preventing liquid splashing and reducing pollution to the operating environment. By guiding the liquid flow to the machining cavity, the guide plate not only keeps the operating window area clean but also ensures that the liquid plays a better cooling and cleaning role during machining, improving machining accuracy and efficiency.

[0019] In a further preferred embodiment, the dental prosthesis carving machine has a guide hole, which is inclined to allow the liquid on the guide plate to flow back.

[0020] The effect of the above solution is that the guide hole, in cooperation with the guide plate, forms a tight and efficient liquid return channel, effectively guiding the coolant back from the operating window area. Compared with solutions such as strip guide channels, the design of the guide hole not only occupies less space, but also effectively reduces the possibility of liquid accumulation. By setting it at an angle, the guide hole can accurately guide the coolant back to the processing chamber, avoiding liquid stagnation or accumulation on the outer wall. Its advantages are: (1) more compact and space-saving, suitable for dental engraving machines with limited space; (2) by closing the return path, reducing the risk of liquid leakage and enhancing the sealing and protection capabilities of the equipment; (3) the angled setting ensures that the liquid can return quickly, avoids liquid stagnation, improves return efficiency, and reduces the risk of contamination.

[0021] In a further preferred embodiment, the processing cavity is provided with a drain hole, and the drain hole discharges waste liquid to a water receiving bucket below through a drain pipe. A water receiving plate is provided above the water receiving bucket.

[0022] The above solution is effective because, during wet machining, coolant and cutting waste are discharged through the drain hole to the water inlet pipe. However, accidental leakage of waste liquid can still occur during machining or drainage. Without effective collection measures, leaked waste liquid will directly contaminate critical components of the equipment, affecting its normal operation and service life. By installing a water inlet plate, leaked waste liquid can be quickly collected, thus preventing it from directly contacting external or internal components of the equipment, reducing the risk of equipment failure due to contamination. This design effectively prevents the spread and retention of waste liquid, ensuring the cleanliness and long-term stability of the equipment.

[0023] In a further preferred embodiment, the guide hole is formed in the guide pipe, and the outlet of the guide pipe is located above the water receiving plate.

[0024] The advantages of the above solution are as follows: By creating guide holes in the guide pipe and placing the outlet of the guide pipe above the receiving plate, the flow path of the waste liquid is further optimized. The guide holes can precisely control the direction of liquid flow, ensuring that the waste liquid flows smoothly to the receiving plate without stagnation or overflow, thereby improving the waste liquid return efficiency and preventing the waste liquid from staying in the drainage system for a long time. Due to the cooperation between the guide pipe and the receiving plate, the waste liquid can be quickly guided to the collection area, avoiding the risk of pollution caused by slow flow rate or liquid accumulation.

[0025] In a further preferred embodiment, the dental prosthesis carving machine has a panel attached to the outer wall of the operating window, and the guide tube is integrally formed with the panel.

[0026] The advantages of the above solution are as follows: by integrating the guide pipe with the panel, the structural design is simplified, avoiding potential sealing failures associated with multi-component connections. This integrated design improves the fit between the panel and the guide pipe, reducing potential leakage points at joints and connections, thereby enhancing overall sealing and ensuring that waste liquid does not leak from any gaps. Furthermore, the integrated design of the guide pipe and panel reduces the complexity of the assembly process, improving production efficiency and reliability. Therefore, the integrated design of the panel and guide pipe not only enhances the overall stability of the equipment but also ensures precise guidance of liquid flow, preventing waste liquid from stagnating around the outer wall of the operating window or flowing backwards.

[0027] A dental prosthesis carving machine includes the operating window sealing structure described above. Since the dental prosthesis carving machine incorporates all the technical features of the aforementioned operating window sealing structure, it also possesses all the technical effects of the aforementioned operating window sealing structure, which will not be elaborated further.

[0028] Compared with the prior art, the sealing structure for the operating window of a dental prosthesis carving machine provided by this utility model includes a window baffle and a first sealing frame. The first sealing frame is rectangular and located on the outside of the operating window. The window baffle can be rotatably connected to the body of the dental prosthesis carving machine and can cover the first sealing frame. The side opening and closing method is more flexible in terms of space utilization, especially suitable for environments with limited operating space. It avoids the interference problem caused by insufficient space when opening and closing the top and bottom cover plates. At the same time, it allows the operator to open and close the window baffle more easily with one hand and has enough space to complete operations such as changing the material tray, without being hindered by the top and bottom opening. The closed baffle blocks the operating space; in addition, the side-opening structure is more stable during equipment operation, reducing the risk of accidental opening due to the weight of the cover or vibration; the protruding design of the first sealing frame increases the contact area of ​​the sealing structure, allowing the window baffle to form a tighter fit with the first sealing frame when closed, thereby significantly improving the sealing performance and effectively preventing the leakage of dust, debris, coolant and lubricant. At the same time, the protruding first sealing frame can also play a guiding role, ensuring that the window baffle always moves along a predetermined trajectory during opening and closing, avoiding sealing failure caused by offset or misalignment.

[0035] This utility model provides a sealing structure for the operating window of a dental prosthesis carving machine and a dental prosthesis carving machine. To make the purpose, technical solution and effect of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and examples.

[0036] This utility model provides a sealing structure for the operating window of a dental prosthesis carving machine, such as... Figure 2 As shown, it includes: a window baffle 200 and a first sealing frame 100. The window baffle 200 is connected to the denture carving machine body by a side-rotating connection, such as by using a hinge structure to fix it to one side of the operating window, so that the window baffle 200 can rotate and open and close in the horizontal direction. The first sealing frame 100 is rectangular and made of wear-resistant and corrosion-resistant rubber or silicone material, and is fixed to the outer edge of the operating window by bolts or adhesive. The protruding design of the first sealing frame 100 allows it to fit tightly with the window baffle 200 when closed, forming multiple sealing barriers.

[0037] The side-rotating design of the window baffle 200 offers greater flexibility in space utilization, making it particularly suitable for environments with limited operating space. It avoids the interference problems caused by insufficient space when using top-and-bottom opening covers. Operators can easily open and close the window baffle 200 with one hand, and have sufficient space to perform operations such as tray replacement during the opening and closing process, without having their operating space obstructed by the top-and-bottom opening covers. Furthermore, the side-opening structure provides greater stability during equipment operation, reducing the risk of accidental opening due to the cover's own weight or vibration, further enhancing the equipment's safety and ease of operation.

[0038] The protruding design of the first sealing frame 100 increases the contact area of ​​the sealing structure, allowing the window baffle 200 to form a tighter fit with the first sealing frame 100 when closed. This significantly improves sealing performance, effectively preventing leakage of dust, debris, coolant, and lubricant. Furthermore, its guiding function ensures that the window baffle 200 always moves along a predetermined trajectory during opening and closing, avoiding sealing failure due to offset or misalignment. Simultaneously, when closed, the window baffle 200 completely covers the first sealing frame 100, forming multiple sealing barriers. This effectively isolates external contaminants from entering the machining cavity and prevents internal cutting waste and liquid spillage, ensuring a clean machining environment and stable equipment operation.

[0039] In a further preferred embodiment of this utility model, the operating window sealing structure further includes a second sealing frame 300. The second sealing frame 300 is disposed on the side of the window baffle 200 facing the operating window, and is made of the same wear-resistant and corrosion-resistant material (such as rubber or silicone) as the first sealing frame 100. It is fixed to the inner edge of the window baffle 200 by adhesive or embedded installation. When the window baffle 200 is closed, the outer edge of the second sealing frame 300 is tightly fitted with the inner edge of the first sealing frame 100, forming a double sealing structure. When the window baffle 200 is closed, the outer edge of the second sealing frame 300 and the inner edge of the first sealing frame 100 form a tight contact. The double sealing structure not only increases the sealing contact area, but also effectively prevents the leakage of dust, debris, coolant, and lubricant through two layers of sealing barriers. In addition, the second sealing frame 300 also plays a compensatory role. Even if the first sealing frame 100 experiences slight wear or deformation due to long-term use, the second sealing frame 300 can still ensure the sealing effect, thereby extending the service life of the sealing structure. During the opening and closing of the window baffle 200, the flexible material of the second sealing frame 300 can adapt to the shape changes of the first sealing frame 100, ensuring that the two are always tightly fitted, thus avoiding sealing failure caused by processing errors or installation deviations. At the same time, the double sealing structure can maintain stable sealing performance even under high-speed operation or vibration environments, further improving the overall operating efficiency and safety of the equipment.

[0040] Furthermore, a water receiving trough 400 is provided below the second sealing frame 300, and a water-absorbing component is installed inside the water receiving trough 400 to prevent liquid splashing. The water receiving trough 400 is made of corrosion-resistant material (such as stainless steel or engineering plastic), its shape matches the second sealing frame 300, and it is fixed to the inner bottom of the window baffle 200 by bolts or clips. The water-absorbing component is made of highly absorbent material (such as sponge or fiber fabric) and fills the inside of the water receiving trough 400, which can quickly absorb and store liquid. During equipment operation, coolant or lubricant may splash due to high-speed cutting or vibration. The water receiving trough 400 can effectively collect these liquids, preventing them from overflowing and contaminating the working environment. The water-absorbing component quickly absorbs liquid through its high absorbency, preventing liquid from accumulating or splashing out in the water receiving trough 400, thereby ensuring the cleanliness of the processing chamber and the stable operation of the equipment. In addition, the replaceable design of the water-absorbing component facilitates maintenance. When the water-absorbing component is saturated, the operator can easily replace it, ensuring the continuous liquid absorption capacity of the water receiving trough 400. During the opening and closing of the window baffle 200, the water receiving trough 400 effectively prevents liquid splashing, avoiding it from reaching operators or the outside of equipment and reducing the risk of accidents. At the same time, this design reduces the erosion of the sealing structure by liquid, extending the service life of the first sealing frame 100 and the second sealing frame 300.

[0041] According to another aspect of this utility model, a return slope 120 is provided at the lower end of the first sealing frame 100, such as... Figure 5 As shown, the return slope 120 is inclined towards the machining cavity to facilitate smooth liquid return during wet machining. The return slope 120 is made of the same corrosion-resistant material (such as rubber or silicone) as the first sealing frame 100 and is fixed to the lower end of the first sealing frame 100 by integral molding or splicing. Its inclination angle is optimized to ensure that the liquid can quickly and smoothly return to the machining cavity. During wet machining, coolant or lubricant may splash or accumulate near the sealing structure due to cutting operations. The return slope 120, through its inclined design, guides this liquid back to the machining cavity, preventing liquid accumulation or overflow around the sealing structure. This not only reduces liquid erosion of the sealing structure but also prevents liquid contamination of the working environment, ensuring the cleanliness of the machining process and the stability of equipment operation. Furthermore, by guiding the liquid back to the machining cavity, the return slope 120 reduces liquid residue around the sealing structure, lowering the difficulty of cleaning and maintenance. Meanwhile, the 120° tilt angle design of the reflux ramp can also adapt to liquids of different viscosities, ensuring efficient liquid reflux under various wet processing conditions.

[0042] Preferably, a sealing strip 900 is provided on the outer end face of the first sealing frame 100, and a guide plate 500 is installed below the sealing strip 900. The sealing strip 900 is made of highly elastic, corrosion-resistant rubber or silicone material and is fixed to the outer end face of the first sealing frame 100 by embedding or adhesive, ensuring that it can form a tight seal with the window baffle 200 when closed. The guide plate 500 is made of corrosion-resistant material (such as stainless steel or engineering plastic) and is fixed to the lower part of the first sealing frame 100 by bolts or clips. Its design is inclined towards the processing cavity so that liquid can flow back smoothly. When the window baffle 200 is closed, a tight contact surface is formed between the sealing strip 900 and the window baffle 200, effectively preventing the leakage of dust, debris, coolant and lubricant. At the same time, the highly elastic material of the sealing strip 900 can adapt to the slight deformation or vibration of the window baffle 200, ensuring that a good sealing effect is maintained at all times during equipment operation. The inclined design of the baffle 500 optimizes the liquid return path. During wet processing, splashed or accumulated liquid can quickly return to the processing chamber through the baffle 500, avoiding liquid accumulation or overflow around the sealing structure.

[0043] Furthermore, the dental prosthesis carving machine has a 600mm guide hole (e.g., Figure 2 and Figure 4As shown, the guide hole 600 is inclined and cooperates with the guide plate 500 to allow the liquid on the guide plate 500 to flow smoothly back into the machining chamber. The guide hole 600 is made of corrosion-resistant material, and its inclination angle is optimized to ensure that the liquid can flow quickly and smoothly. The position of the guide hole 600 matches the inclination direction of the guide plate 500, forming a continuous liquid return path. During wet machining, the liquid on the guide plate 500 quickly flows back to the machining chamber through the guide hole 600, avoiding liquid accumulation or overflow around the sealing structure. This not only reduces the erosion of the sealing structure by the liquid, but also prevents liquid from contaminating the working environment, ensuring the cleanliness of the machining process and the stability of equipment operation. At the same time, the inclined design of the guide hole 600 can adapt to liquids of different viscosities, ensuring efficient liquid return under various wet machining conditions. The guide hole 600 has a simple structure and is easy to maintain; the inclined design reduces liquid residue and lowers the difficulty of cleaning and maintenance.

[0044] Furthermore, a drainage hole 110 is provided at the bottom of the machining cavity, such as... Figure 3 As shown, the drain hole 110 discharges waste liquid to the receiving tank 700 below via a drain pipe. The drain hole 110 is made of corrosion-resistant material, and its diameter is optimized to ensure rapid discharge of waste liquid without clogging. The drain pipe, whether flexible or rigid, connects the drain hole 110 to the receiving tank 700 (e.g.,...). Figures 2 to 4 As shown), this forms a complete waste liquid discharge system. A water receiving plate 800 (as shown) is installed above the water receiving tank 700. Figures 2 to 4 As shown, the water receiving plate 800 is made of corrosion-resistant material and is fixed above the water receiving tank 700 by a bracket. It is used to catch any dripping liquid and prevent it from directly entering the outside of the water receiving tank 700. During wet processing, waste liquid generated in the processing chamber is quickly discharged through the drain hole 110, preventing liquid accumulation in the processing chamber, thus reducing the corrosion of the internal structure of the equipment and ensuring a clean processing environment. The water receiving plate 800 provides secondary protection by catching any dripping liquid and preventing it from splashing onto the outside of the water receiving tank 700 or the ground, further improving the operational safety of the equipment.

[0045] In practical implementation, the guide hole 600 is opened in the guide pipe 10a (e.g. Figure 6Inside (as shown), the outlet of the guide pipe 10a is positioned above the receiving plate 800. The guide pipe 10a is made of corrosion-resistant material, and its internal channels are optimized to ensure smooth liquid flow without clogging. The outlet of the guide pipe 10a is aligned with the receiving plate 800, allowing liquid flowing from the guide hole 600 to drip directly onto the receiving plate 800, preventing splashing or contamination of the surrounding environment. During wet processing, liquid enters the guide pipe 10a through the guide hole 600 and is precisely discharged above the receiving plate 800 through the outlet of the guide pipe 10a. This not only ensures centralized collection of the liquid but also prevents splashing or overflow during discharge, thus maintaining a clean working environment. The receiving plate 800 serves to receive and guide the liquid, further directing it to the receiving bucket 700, preventing direct dripping onto the ground or outside the equipment. In addition, the structure of the guide pipe 10a is simple and easy to maintain. The design of its outlet position makes it easy for operators to observe the liquid discharge and clean any possible blockages or residues in a timely manner.

[0046] Preferably, the dental prosthesis carving machine has a panel 10 attached to the outer wall of the operating window (e.g., Figure 6 As shown, the guide pipe 10a is integrally formed with the panel 10. The panel 10 is made of corrosion-resistant, high-strength materials (such as engineering plastics or stainless steel) and is fixed to the outer wall of the operating window by bolts or adhesive, ensuring a tight fit with the equipment body. The integral forming of the guide pipe 10a and the panel 10 creates a seamless connection, enhancing the overall structural integrity and avoiding the risk of liquid leakage at the connection point. The integral forming not only simplifies the installation process but also reduces gaps at the connection point, preventing liquid leakage during flow. The fitted design of the panel 10 further optimizes the appearance and sealing performance of the operating window, while providing stable support for the guide pipe 10a, ensuring its stable position and function during equipment operation. Furthermore, the integral forming design enhances the durability and ease of maintenance of the equipment. Since there is no seam between the guide pipe 10a and the panel 10, the possibility of liquid residue and corrosion is reduced, extending the service life of the equipment. At the same time, the modular design of the panel 10 facilitates disassembly and replacement, allowing operators to easily maintain the guide pipe 10a and the panel 10, ensuring the long-term stable operation of the liquid discharge system.
