Description

Technical Field

[0001] This invention relates to aerated concrete cutting technology, belonging to the field of concrete processing, and specifically to a cleaning fixture for aerated concrete billet cutting line and its usage method. Background Technology

[0002] Autoclaved aerated concrete (AAC) is a lightweight porous silicate product made primarily from siliceous and calcareous materials, with the addition of a foaming agent, through processes such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing.

[0003] In the cutting process, the aerated concrete billet is moved to the cutting equipment by a loading trolley. Currently, the common method for horizontal cutting is: the taut cutting line is laid across the support frame, and the aerated concrete billet moves through multiple cutting lines to complete the corresponding cutting.

[0004] To prevent concrete residue from adhering to the cutting line after cutting and affecting subsequent cutting, and to prevent the billet from sticking together due to the gap between the upper and lower cuts during the subsequent autoclaving process, the cutting line needs to be coated with wax and cleaned with water during the rotary cutting process. For example, the Chinese utility model patent with application number CN202122063479.1, "Cutting Device for Aerated Concrete Blocks," discloses that: a servo motor drives the cutting wire to perform counterclockwise uniform reciprocating motion; an axial flow fan is powered on to generate suction to pick up concrete debris; and... The wax coating holder wraps around the cutting wire to evenly adhere liquid wax to the outside of the wire. However, this method has several problems: 1. Negative pressure adsorption of debris not only fails to wipe the surface of the cutting line, resulting in incomplete cleaning, but also requires increased axial fan power for stubborn debris, leading to high overall noise levels. The axial fan must remain operational throughout the cutting process. 2. The wax coating holder wraps around the cutting wire to apply liquid wax, which often results in solidification of the wax due to the inability to heat it. Furthermore, the movement of the cutting wire makes it difficult to ensure complete coating of its surrounding area.

[0005] Chinese invention patent application number 202110080098.6, entitled "Aerated Concrete Block Cutting Machine," discloses that: an impregnation wheel is rotatably installed in a paraffin wax container, and the cutting wire passes around the bottom of the impregnation wheel and through a wire winding wheel; a heat exchange pipe is installed in the paraffin wax container. This invention can effectively solve the problems of wax solidification and complete coating. However, the method of immersing wax often faces a problem: as the liquid wax is applied to the cutting line, the amount of wax in the container gradually decreases, causing the liquid level to drop and affecting the application of liquid wax to the cutting line at a fixed height. The traditional technical solution is to use a liquid level sensor to detect the liquid level in real time. When the wax level is lower than the set height, the controller controls the replenishment of liquid or reminds manual replenishment. This method is relatively complex, requiring additional liquid level sensors and other electrical equipment. In addition, the impregnation wheel rotates as it moves with the cutting line, which will drive the wax to stir and change the surface of the wax, thus affecting the detection of the liquid level sensor. Summary of the Invention

[0006] The purpose of this invention is to provide a cleaning fixture for the cutting line of aerated concrete billets. It has a simple and compact structure, which not only enables different cleaning methods for debris on the cutting line, avoiding excessive water consumption and noise, but also allows for adjustment of the wax liquid level without affecting the detection accuracy by using non-electrical equipment, making it more convenient.

[0007] To achieve the above objectives, a cleaning fixture for the cutting line of aerated concrete billets is provided, comprising:

[0008] The cleaning chamber has a first inner cavity and a second inner cavity. The bottom of the first inner cavity is provided with a slag discharge port, and the second inner cavity is provided with an immersion wheel for immersing the cutting line in wax liquid and a drain port at the bottom.

[0009] The cleaning mechanism has a support shaft rotatably installed in the first inner cavity with its axis perpendicular to the direction of movement of the cutting line, and a cleaning cotton located in the middle of the support shaft with a mesh-like water-permeable structure inside; the support shaft is provided with a through-hole assembly for inputting water into the cleaning cotton.

[0010] The wax impregnation mechanism has a heat-conducting plate that slides to divide the second inner cavity into an upper and lower part, and a suspended block whose periphery matches the inner wall of the upper part of the second inner cavity and whose density is less than that of the wax liquid; the lower part of the second inner cavity is filled with water and equipped with a heating mechanism, and a limiting ring is provided above the heat-conducting plate and the suspended block to limit their movement.

[0011] The upper part of the second inner cavity is provided with an injection hole that is radially connected to the water pressure source and is sealed by a suspension block; the suspension block is provided with a hole assembly that is connected to the lower part of the second inner cavity by a hose at one end, and when the suspension block descends to a certain height, the other end of the hole assembly is connected to the injection hole.

[0012] In some embodiments, the through-hole assembly includes a first through-hole arranged along the axis of the support shaft, and a second through-hole arranged radially in the middle of the support shaft and communicating with the first through-hole;

[0013] One end of the support shaft is connected to the water pressure source, and the other end is connected to the injection hole.

[0014] In some embodiments, a support sleeve rotating in tandem is provided between the cleaning cotton and the support shaft;

[0015] The inner wall of the support sleeve has a spirally arranged guide groove, and the circumference has multiple connecting holes that are spirally aligned with the guide groove; the second through hole communicates with the guide groove, and the guide groove communicates with the multiple connecting holes.

[0016] In some embodiments, the hole assembly includes:

[0017] Blind holes are arranged from the periphery of the suspension block toward the axis and are located above the injection holes;

[0018] The third through hole is arranged vertically, with one end connected to the blind hole and the other end connected to the lower part of the second inner cavity via a flexible tube.

[0019] In some embodiments, the hole assembly further includes multiple annular grooves arranged at vertical intervals;

[0020] The spacing between the edges of adjacent annular grooves is smaller than the diameter of the injection hole; the blind hole is located at the uppermost annular groove, and the injection hole is connected to one of its annular grooves.

[0021] In some embodiments, the axis of the injection hole is arranged at an angle, with the downward angled end facing the suspension block.

[0022] In some embodiments, an adjusting block and a spring are also included;

[0023] The spring is mounted on the stepped structure at the end of the support shaft, and the adjusting block is threaded onto the cleaning box and compresses the spring.

[0024] The present invention also aims to provide a method for using a cleaning fixture for the cutting line of aerated concrete billets. By embedding the cutting line into part of the cleaning cotton and allowing cleaning water to permeate from the inside of the cleaning cotton to the outside, the cleaning state of the cutting line can be adjusted by the amount of water introduced. By blocking or connecting the injection hole to the lower part of the second inner cavity with a suspension block, the heat-conducting plate raises the overall wax liquid, thereby adjusting the height of the wax liquid level and ensuring that the wax liquid level remains stable even after the amount of wax liquid is reduced.

[0025] A method for using a cleaning fixture for the cutting line of aerated concrete billets includes the following steps:

[0026] a. The wire cutter is in a taut and moving state and can be embedded in part of the cleaning cotton. The water pressure source introduces cleaning water into the first through hole coaxial with the support shaft. On one hand, the cleaning water enters the guide groove arranged spirally on the inner wall of the support sleeve from the first through hole and the radially arranged second through hole. The guide groove evenly distributes and temporarily stores the cleaning water, and then enters the interior of the cleaning cotton from the connecting hole, and penetrates from the inside to the outside to clean the cutting wire. The state of slag discharge cleaning or wet cleaning is adjusted by the amount of water introduced. On the other hand, the cleaning water enters the injection hole of the second inner cavity from the end of the first through hole and is sealed by the suspended block with a density less than that of wax liquid.

[0027] b. The heating mechanism heats the aqueous solution in the lower part of the second inner cavity and transfers the heat to the wax liquid in the upper part of the second inner cavity through the heat-conducting plate. When the cutting line is coated with wax liquid for a long time and the liquid level drops, the less dense suspended block also drops. The injection hole on the second inner cavity is connected to the blind hole arranged radially on the suspended block. Water enters the lower part of the second inner cavity in sequence from the injection hole, blind hole, third through hole arranged vertically, and hose, pressurizing the lower part of the second inner cavity and causing the heat-conducting plate to move upward.

[0028] c. The upward movement of the heat-conducting plate will lift the wax liquid located in the upper part of the second inner cavity from bottom to top. The wax liquid level rises and drives the suspension block to rise as well. The suspension block re-seals the injection hole, so that the wax liquid level can remain at a stable height even after the amount of wax liquid is reduced.

[0029] Compared with existing technologies, this aerated concrete billet cutting line cleaning fixture achieves cleaning by embedding the cutting line within a portion of the cleaning cotton and allowing cleaning water to permeate from the inside of the cleaning cotton outwards. This avoids excessive water consumption and noise. Furthermore, the slag discharge cleaning or immersion cleaning state can be adjusted by adjusting the amount of water entering the fixture. By sealing or connecting the injection hole to the lower part of the second inner cavity with a suspended block, the heat-conducting plate raises the overall wax liquid. This allows for adjustment of the wax liquid level without affecting the detection accuracy, even after the amount of wax liquid is reduced.

[0030] In some embodiments, one end of the support shaft is connected to a water pressure source and the other end is connected to an injection hole. The water pressure source can not only provide cleaning water to the cleaning mechanism, but also provide water medium to the lower part of the second inner cavity in the wax impregnation mechanism. Using a single input source (water pressure source) to achieve different functions saves more resources.

[0031] In some embodiments, a support sleeve is provided between the cleaning cotton and the support shaft. The inner wall of the support sleeve has a spirally arranged guide groove and a connected hole, so that the cleaning water can be temporarily stored in the guide groove and provide water for the cleaning cotton. The water is evenly distributed in the cleaning cotton along the guide groove and the connected hole, so as to avoid the cleaning cotton being too dry in some parts and thus reducing the cleaning effect of the debris on the cutting line.

[0032] In some embodiments, the stepped structure at the end of the support shaft is provided with a spring and an adjusting block for adjusting the elastic force of the thread. Therefore, by adjusting the position of the adjusting block appropriately, the support shaft causes the cleaning cotton rotating at the same speed to decrease relative to the cutting line due to the elastic force. When the cleaning cotton rotates, it "wipes" the debris on the cutting line, thereby removing the debris that is more firmly attached to the cutting line and cleaning the cutting line more thoroughly.

[0047] The invention will now be further described with reference to the accompanying drawings.

[0048] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figure 1 , Figure 2 As shown, this aerated concrete billet cutting line cleaning fixture includes:

[0050] The cleaning chamber 20 has a first inner cavity 21 and a second inner cavity 24. The second inner cavity 24 is provided with an immersion wheel for immersing the cutting line 14 in wax liquid and a drain port 43 at the bottom.

[0051] Its characteristic is that it further includes:

[0052] The cleaning mechanism 30 has a support shaft 31 rotatably installed in the first inner cavity 21 with its axis perpendicular to the direction of movement of the cutting line 14, and a cleaning cotton 34 located in the middle of the support shaft 31 with a mesh-like water-permeable structure inside; the support shaft 31 is provided with a through hole assembly for inputting water into the cleaning cotton 34.

[0053] The wax impregnation mechanism has a heat-conducting plate 44 that slides and seals to divide the second inner cavity 24 into an upper part and a lower part, and a suspension block 42 whose periphery matches the inner wall of the upper part of the second inner cavity 24 and whose density is less than that of the wax liquid; the lower part of the second inner cavity 24 is filled with water and equipped with a heating mechanism 45, and a limiting ring 41 is provided above the heat-conducting plate 44 and the suspension block 42 to limit their movement.

[0054] The upper part of the second inner cavity 24 is provided with an injection hole 47 that is radially connected to the water pressure source and is sealed by a suspension block 42; the suspension block 42 is provided with a hole assembly that is connected to the lower part of the second inner cavity 24 through a hose 46, and when the suspension block 42 descends to a certain height, the other end of the hole assembly is connected to the injection hole 47.

[0055] Specifically, the cleaning chamber 20 is the general term for the overall cleaning support, such as... Figure 2 , Figure 7As shown, the cutting line 14 is wound around the outside of the driving wheel 12 and the driven wheel 13, and the drive motor 11 drives the driving wheel 12. In one embodiment, the axes of the driving wheel 12 and the driven wheel 13 are arranged vertically, so that when the cutting line 14 is in the horizontal plane, the first inner cavity 21 and the second inner cavity 24 on the cleaning chamber 20 are arranged side-by-side. Figure 7 The driving wheel 12 and driven wheel 13 are arranged left and right respectively. This cleaning fixture is arranged in opposite directions at the driving wheel 12 and driven wheel 13. Specifically, the upper left exit wire of the cutting line 14 passes through the second inner cavity 24 for waxing, the upper right entry wire passes through the first inner cavity 21 for cleaning, the lower right exit wire passes through the second inner cavity 24 for waxing, and the lower left entry wire passes through the first inner cavity 21 for cleaning. This cycle is repeated to achieve cleaning and waxing of the cutting line 14. In another embodiment 2, the axes of the driving wheel 12 and driven wheel 13 are arranged horizontally, so that when the cutting line 14 is in a vertical plane, the first inner cavity 21 and the second inner cavity 24 are arranged vertically. Figure 3 As shown, in this case, the cleaning chamber 20 can be divided into an upper cleaning chamber and a lower cleaning chamber, which are arranged in opposite directions.

[0056] A notch 22 is provided in the middle of the first inner cavity 21 facing the direction of movement of the cutting line 14. The notch 22 facilitates the installation of the cleaning mechanism 30 and the passage of the cutting line 14. The lower end of the notch 22 is higher than the bottom end of the first inner cavity 21, so that space is left for storing cleaning water. The cleaning cotton 34 of the cleaning mechanism 30 can be made of traditional cleaning cotton, which has good wear resistance and water permeability. The heating mechanism 45 in the wax impregnation mechanism can be a heating wire of a traditional structure.

[0057] In this embodiment, during operation, the cutting line 14 is wound around the outside of the driving wheel 12 and the driven wheel 13, and then passes through and contacts the cleaning cotton 34 in the first inner cavity 21 and the impregnation wheel in the second inner cavity 24.

[0058] During cutting, the cutting wire 14 is in a taut and moving state. When it comes into contact with the cleaning cotton 34, it compresses the cleaning cotton 34. Because the cleaning cotton 34 has a mesh-like permeable structure and a certain degree of compressive elasticity, the cutting wire 14 can be embedded in part of the cleaning cotton 34. Cleaning water enters the cleaning cotton 34 through the through-hole assembly of the support shaft 31 to wet it, cleaning the cutting wire 14 cut from the blank. The cleaning state is adjusted by the amount of water introduced. That is, when the amount of water introduced is small, the cleaning cotton 34 can store the cleaning water for a short time and act on it. The cutting line 14 is wetted and cleaned. When the water flow is too large, the water in the cleaning cotton 34 can carry the debris on the cutting line 14 out for slag removal and cleaning, and finally discharge it from the slag discharge port 23 at the bottom of the first inner cavity 21. This slag removal method is simple and compact. Different cleaning methods for debris on the cutting line 14 can be achieved by controlling the water volume. Compared with the direct water pressure spraying method, it is more targeted and can reduce water consumption. Compared with the negative pressure adsorption method, it can reduce the overall noise, and the water can be stored in the cleaning cotton 34, which can be in a non-water supply state for a short time.

[0059] The upper part of the second inner cavity 24 is filled with liquid wax. The suspension block 42 is located on the surface of the liquid wax and is limited by the limiting ring 41, which also blocks the injection hole 47. The heating mechanism 45 heats the aqueous solution in the lower part of the second inner cavity 24 and transfers the heat to the liquid wax through the heat-conducting plate 44 to prevent the liquid wax from solidifying. When the liquid wax level drops due to prolonged use, the less dense suspension block 42 also drops, so that the injection hole 47 on the second inner cavity 24 connects with the hole assembly on the suspension block 42, and the hole assembly connects with the lower part of the second inner cavity 24. That is, water enters the lower part of the second inner cavity 24 from the injection hole 47 and the hole assembly, pressurizing the heat-conducting plate 44 and lifting the liquid wax in the upper part of the second inner cavity 24 from bottom to top. The liquid wax level rises and drives the suspension block 42 to rise. The suspension block 42 re-blocks the injection hole 47, so that the liquid wax level can remain at a stable height after the amount of liquid wax is reduced.

[0060] To ensure that the suspension block 42 blocks the injection hole 47, the periphery of the suspension block 42 needs to match the upper part of the inner wall of the second inner cavity 24. This effectively reduces the impact of the wax liquid agitation caused by the movement of the cutting line 14 on the suspension block 42. It is more convenient to adjust the wax liquid level height without using non-electrical equipment and without affecting the detection accuracy.

[0061] The limiting ring 41 above the suspension block 42 limits the suspension block 42 to prevent the wax liquid level from being too high in the initial state. The limiting ring 41 above the heat-conducting plate 44 can approach the injection hole 47, which increases the upward stroke of the heat-conducting plate 44. It should be noted that the movement of the suspension block 42 and the heat-conducting plate 44 will not interfere with the impregnation wheel.

[0062] like Figure 2As shown, in some embodiments, the through-hole assembly includes a first through-hole 311 arranged along the axial direction of the support shaft 31, and a second through-hole 312 arranged radially in the middle of the support shaft 31 and communicating with the first through-hole 311.

[0063] One end of the support shaft 31 is connected to the water pressure source, and the other end is connected to the injection hole 47;

[0064] Specifically, the water pressure source provides cleaning water to the cleaning mechanism 30. When cleaning the cutting line 14, the cleaning water enters the innermost side of the cleaning cotton 34 through the first through hole 311 and the second through hole 312, and penetrates from the inside to the outside to clean the cutting line 14.

[0065] One end of the support shaft 31 is connected to the water pressure source, and the other end is connected to the injection hole 47. That is, the water pressure source can not only provide cleaning water for the cleaning mechanism 30, but also provide water medium for the lower part of the second inner cavity 24 in the wax impregnation mechanism. Using a single input source (water pressure source) to achieve different functions saves more resources. In addition, a manually controlled valve can be provided at the injection hole 47. The water pressure source can be connected to the lower part of the second inner cavity 24 by manually opening and closing the valve, so that the water pressure source can provide cleaning water for the cleaning mechanism 30 alone, making it more flexible to use.

[0066] like Figure 2 , Figure 4 As shown, in some embodiments, a support sleeve 32 that rotates in the same direction is provided between the cleaning cotton 34 and the support shaft 31;

[0067] The inner wall of the support sleeve 32 has a spirally arranged guide groove 322, and the periphery has a plurality of connecting holes 321 that are spirally aligned with the guide groove 322; the second through hole 312 communicates with the guide groove 322, and the guide groove 322 communicates with the plurality of connecting holes 321.

[0068] Specifically, the function of the support sleeve 32 is to store water and distribute water evenly. It is fitted between the cleaning cotton 34 and the support shaft 31 and is axially limited by a pair of limiting blocks 33 located on both sides of it. That is, the pair of limiting blocks 33 are located on both sides of the axial direction of the support sleeve 32 and clamp and fix the support sleeve 32 and the cleaning cotton 34 to ensure that the support sleeve 32, the cleaning cotton 34 and the support shaft 31 rotate together.

[0069] The cleaning water enters the guide groove 322 on the inner wall of the support sleeve 32 through the first through hole 311 and the second through hole 312. Since the guide groove 322 is spirally arranged, the cleaning water can not only flow in the guide groove 322, that is, be distributed axially to fill the guide groove 322, but also be temporarily stored and provide water for the cleaning cotton 34. The multiple connecting holes 321 are spirally aligned with the guide groove 322 and are interconnected, so that the cleaning water in the guide groove 322 can enter the inner side of the cleaning cotton 34 through the multiple connecting holes 321. This spiral method makes the cleaning water evenly distributed in the cleaning cotton 34, avoiding the fact that some parts of the cleaning cotton 34 are relatively dry, which will reduce the cleaning effect of the debris on the cutting line 14.

[0070] like Figure 2 , Figure 5 As shown, in some embodiments, the hole assembly includes:

[0071] Blind hole 422 is arranged from the periphery of suspension block 42 toward the axis and is located above injection hole 47;

[0072] The third through hole 423 is arranged vertically, with one end connected to the blind hole 422 and the other end connected to the lower part of the second inner cavity 24 through the flexible tube 46;

[0073] Specifically, under normal circumstances, the periphery of the suspension block 42 blocks the injection hole 47; when the suspension block 42 descends with the wax liquid level, the blind hole 422 connects with the injection hole 47, that is, water enters the lower part of the second inner cavity 24 in sequence from the injection hole 47, the blind hole 422, the third through hole 423, and the hose 46, pressurizing the lower part of the second inner cavity 24 and causing the heat conduction plate 44 to move upward.

[0074] like Figure 5 As shown, in some embodiments, the hole assembly further includes multiple annular grooves 421, which are arranged vertically at intervals.

[0075] The gap between the edges of the adjacent annular grooves 421 is smaller than the diameter of the injection hole 47; the blind hole 422 is located at the uppermost annular groove 421, and the injection hole 47 is connected to one of its annular grooves 421.

[0076] Specifically, to meet the pressure increase requirements of the lower part of the second inner cavity 24 and the upward movement of the heat-conducting plate 44, the water located in the injection hole 47 needs to have a certain pressure; when the wax liquid level does not drop and the suspension block 42 blocks the injection hole 47, if the suspension block 42 does not have an annular groove 421 on its circumference and directly blocks the injection hole 47 through its circumference, such as Figure 8 As shown, at this time, the water pressure in the injection hole 47 will act directly radially on the suspension block 42, and the friction between the opposite side of the suspension block 42 and the inner wall of the second inner cavity 24 will increase, causing the suspension block 42 to be unable to follow the wax liquid level down.

[0077] To solve the above problems, multiple annular grooves 421 are arranged at intervals around the suspension block 42. When the wax liquid level has not dropped, pressurized water enters the annular grooves 421 through the injection hole 47. Figure 9 As shown, pressurized water is arranged circumferentially around the suspension block 42, so that the suspension block 42 is evenly stressed and balanced, avoiding excessive friction between the suspension block 42 and the inner wall of the second inner cavity 24.

[0078] As the wax level drops, the suspended block 42 moves downward. Since the gap between the edges of the adjacent annular grooves 421 is smaller than the diameter of the injection hole 47, pressurized water can gradually transition from the lower annular groove 421 to the upper annular groove 421, and keep the suspended block 42 under uniform force in the circumference until the injection hole 47 connects with the blind hole 422 at the uppermost annular groove 421.

[0079] In some embodiments, the axis of the injection hole 47 is arranged at an angle, with the downward angled end facing the suspension block 42;

[0080] Specifically, when the pressurized water in the injection hole 47 acts on the periphery of the suspension block 42, the force exerted by the pressurized water on the suspension block 42 is decomposed into radial and downward forces due to the inclined arrangement of the injection hole 47. This ensures that the suspension block 42 is in a balanced state, that is, when the wax liquid level drops, the suspension block 42 can also drop accordingly.

[0081] like Figure 6 As shown, in some embodiments, the support shaft 31 is rotatably mounted on the slag removal box;

[0082] It also includes an adjusting block 51 and a spring 52;

[0083] Spring 52 is mounted on the stepped structure at the end of support shaft 31, and adjusting block 51 is threaded onto cleaning box 20 and compresses spring 52.

[0084] Specifically, the function of the adjusting block 51 and the spring 52 is to increase the damping of the support shaft 31; that is, to rotate the adjusting block 51 so that it moves axially to adjust the compression of the spring 52. The elastic force of the spring 52 acts on the stepped structure of the support shaft 31, and the friction generated by the elastic force will serve as the damping force for the rotation of the support shaft 31.

[0085] By adjusting the position of the adjusting block 51, the damping of the support shaft 31 causes the relative rotation speed of the cleaning cotton 34 rotating in tandem with the cutting line 14 to decrease. This means that the cleaning cotton 34 and the cutting line 14 will generate less friction. This friction can be used as a "wiping" effect on the debris on the cutting line 14 when the cleaning cotton 34 rotates, thus removing the debris that is more firmly attached to the cutting line 14 and achieving a more thorough cleaning of the cutting line 14.

[0086] When this aerated concrete billet cutting line cleaning fixture is used, the cutting line 14 is in a taut and movable state and can be embedded in part of the cleaning cotton 34. The water pressure source introduces cleaning water into the first through hole 311 coaxial with the support shaft 31. On the one hand, the cleaning water enters the guide groove 322 spirally arranged on the inner wall of the support sleeve 32 from the first through hole 311 and the radially arranged second through hole 312. The cleaning water is evenly distributed and temporarily stored through the guide groove 322, and then enters the interior of the cleaning cotton from the connection hole 321 and penetrates from the inside to the outside to clean the cutting line 14. The state of slag discharge cleaning or wet cleaning is adjusted by the amount of water introduced. On the other hand, the cleaning water enters the injection hole 47 of the second inner cavity 24 from the end of the first through hole 311 and is blocked by the suspension block 42 with a density less than that of wax liquid.

[0087] Heating mechanism 45 heats the aqueous solution in the lower part of the second inner cavity 24 and transfers the heat to the wax liquid in the upper part of the second inner cavity 24 through heat conduction plate 44. When the cutting line 14 is coated with wax liquid for a long time and the liquid level drops, the less dense suspended block 42 also drops. The injection hole 47 on the second inner cavity 24 is connected to the blind hole 422 arranged radially on the suspended block 42. Water enters the lower part of the second inner cavity 24 in sequence from the injection hole 47, blind hole 422, third through hole 423 arranged vertically, and hose 46, pressurizing the lower part of the second inner cavity 24 and causing the heat conduction plate 44 to move upward.

[0088] The heat-conducting plate 44 moves upward to lift the wax liquid located in the upper part of the second inner cavity 24 from bottom to top. The wax liquid level rises and drives the suspension block 42 to rise. The suspension block 42 re-seals the injection hole 47, so that the wax liquid level can still be at a stable height after the amount of wax liquid is reduced.
