Description

Technical Field

[0001] This application relates to the field of food manufacturing technology, specifically to a high-efficiency cleaning transmission structure for a face washing machine. Background Technology

[0002] A dough washing machine is a specialized tool used for washing dough in the production of foods such as cold noodles and gluten. Common dough washing machines typically employ a spiral blade transmission mechanism as the power source for washing. During the washing process, pre-made dough and water are added to the washing chamber of the machine. The spiral blades directly contact the dough and water, driving their rotation to achieve tasks such as mixing, washing, and conveying the materials.

[0003] Traditional dough washing machines typically do not consider blade cleaning or include cleaning components in their transmission structure, as illustrated in patent document CN216874856U. However, dough, especially during kneading and washing, is sticky, and the dissolved starch easily adheres to it. Since the spiral blades come into direct contact with the material, dough residue easily sticks to the blade surface and the rotating shaft's outer surface at the spiral gaps. This residual dough is often difficult to completely remove with water. This long-term residue can breed microorganisms, and the spiral blades will again come into direct contact with the food during the washing process, posing a high food safety risk.

[0004] Therefore, how to clean the drive spiral blades of a facial cleansing machine and reduce the food safety risks caused by material residue on the blade surface has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a high-efficiency cleaning transmission structure for a facial cleansing machine. This transmission structure can realize the inherent functions of the facial cleansing machine and also achieve high-efficiency self-cleaning of the transmission structure.

[0006] In order to achieve the above-mentioned objectives of this application, the following technical solution is adopted: A high-efficiency cleaning transmission structure for a facial cleansing machine, comprising: Cleaning mechanism and screw drive mechanism; The cleaning mechanism includes a steam generator and two or more friction cleaning components; The spiral drive mechanism is the power mechanism of the facial cleansing machine, used to convey the water mixture in the facial cleansing chamber. The rotating shaft of the spiral drive mechanism has a preset cavity extending along its axial direction. The preset cavity of the rotating shaft has an inlet, a drain valve opening, and two or more outlets. The inlet is sealed and connected to the output end of the steam generator. The drain valve opening is equipped with a drain valve. The two or more outlets are distributed adjacent to each other along the axial direction of the rotating shaft. The outlets are located in the gap between two adjacent turns of the spiral blades of the spiral drive mechanism. The outlets are equipped with normally closed pneumatic valves. The spiral drive mechanism is used to convey the friction cleaning component placed in the facial cleansing chamber. The friction cleaning component contacts the spiral blades during the conveying process and uses friction to remove residues on the spiral blades.

[0007] Preferably, the inlet is provided with a rotary joint, and the output end of the steam generator is connected to the inlet through the rotary joint.

[0008] Preferably, the inlet of the preset cavity of the rotating shaft is detachably connected to the output end of the steam generator.

[0009] Preferably, the friction cleaning component is a brush.

[0010] Preferably, the friction cleaning component is spherical, and the outer circumferential surface of the spherical friction cleaning component is its friction structure.

[0011] Preferably, the helical transmission mechanism is a reverse double helical transmission mechanism.

[0012] Preferably, the rotary drive device of the helical transmission mechanism is a reversible drive device.

[0013] Compared with the prior art, the beneficial effects of this application include at least the following: This application incorporates a steam generator, utilizing a pre-set chamber on the rotating shaft to output hot steam to the blades within the washing chamber, softening the dough adhering to them and reducing the difficulty of cleaning residual dough. Furthermore, by adding friction cleaning components to the washing chamber, the friction generated during the transport of these components by the screw drive mechanism effectively removes residual dough. Compared to existing technologies, this application can clean the drive screw blades of the noodle washing machine, reducing food safety risks caused by material residue. Attached Figure Description

[0017] The embodiments of the technical solution of the present invention will be described in detail below with reference to the examples. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and are therefore only examples, and should not be used to limit the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0018] Figure 1 The diagram shows a structure of a face washing machine according to an embodiment of the present invention. The axial direction of the rotating shaft 212 extends from the feeding end of the face washing chamber 310 to the discharging end. The discharging end is provided with a first opening 311. The first opening 311 is equipped with a filtration device such as a screen. The first opening 311 is used to discharge gluten water. The four diamond-shaped holes in the middle of the figure are all outlets 217. Figure 2 This is a schematic diagram of the efficient cleaning transmission structure of a facial cleansing machine according to an embodiment of the present invention. The two axial ends of the rotating shaft 212 are mounted to the mounting opening of the facial cleansing chamber 310 via bearings 214, thereby rotatably connecting the rotating shaft 212 to the facial cleansing chamber 310. Figure 1 Reference for bearing 214 position and steam trap 218 position Figure 2 In both embodiments, the drain valve 218 is located outside the wash compartment 310.

[0019] This application provides a high-efficiency cleaning transmission structure for a facial cleansing machine, including a cleaning mechanism and a screw transmission mechanism. Wherein: The cleaning mechanism includes a steam generator 110 and two or more friction cleaning components; The screw drive mechanism is the power mechanism of the face washing machine, used to convey the water mixture in the face washing chamber 310. The rotating shaft 212 of the screw drive mechanism is provided with a preset cavity 215 extending along its axial direction. The preset cavity 215 of the rotating shaft 212 has an inlet 216, a drain valve 218 opening, and two or more outlets 217. The inlet 216 is sealed and connected to the output end of the steam generator. The drain valve 218 opening is provided with a drain valve 218. The two or more outlets 217 are distributed adjacently along the axial direction of the rotating shaft 212. The outlets 217 are located in the gap between two adjacent turns of the blade wall of the screw blade 213 of the screw drive mechanism. The outlets 217 are provided with normally closed pneumatic valves. The screw drive mechanism is used to convey the friction cleaning component placed in the face washing chamber 310. The friction cleaning component contacts the screw blade 213 during the conveying process and uses friction to remove the residue on the screw blade 213.

[0020] It should be noted that "sealed connection" describes the functional state of the fluid passage, that is, steam can flow from the steam generator 110 into the preset cavity 215 of the rotating shaft 212 without leakage. Therefore, sealed connection can be an intermittent functional state, rather than a permanent physical connection, and should not be understood as the two having to maintain a physical connection at all times.

[0021] It should be noted that the phrase "adjacent along the axial direction" in the context of two or more outlets 217 being distributed adjacently along the axial direction of the rotation shaft 212 means that several outlets 217 are adjacent to each other, and there is a certain distance between every two adjacent outlets 217 along the axial direction of the rotation shaft 212. This is a common definition in the art and should not be interpreted as meaning that the outlets 217 must be collinear (axially). This application does not specifically limit the other arrangement trajectories of the outlets 217. The outlets 217 can be arranged along a helical trajectory (see below for details); they can be collinear (axially); and they can be randomly arranged between the blade gaps, as long as there is a certain distance between adjacent outlets 217 along the axial direction of the rotation shaft 212 in the gap between the helical surfaces of the blades (i.e., the gap between two adjacent blade walls). The adjacent distribution of outlets 217 along the axial direction allows the outlets 217 to cover as much of the blade helical surface and blade wall distributed along the axial length of the rotation shaft 212 as possible, preferably with the outlets 217 covering the entire axial length of the rotation shaft 212 and the entire axial length of the helical blade 213.

[0022] Based on the traditional spiral blade type facial cleanser transmission structure, this application adds a steam generator 110 to provide hot steam, and sets a preset cavity 215 inside the rotating shaft 212 of the spiral transmission mechanism as a flow channel for hot steam. Several outlets 217 are set on the radial side wall of the rotating shaft 212, and an outlet 217 is provided between each two adjacent rings of the spiral blade 213. The hot steam is guided to the spiral surface of the spiral blade 213 by the outlets 217, and the hot steam softens the residual paste and slurry adhering to the spiral surface, which can greatly reduce the difficulty of removing the residue from the blade.

[0023] It should be noted that this application does not specifically limit the connection method between the output end of the steam generator 110 and the inlet 216 of the rotating shaft 212. Regarding the connection between the two, the core technical requirements for ensuring the overall transmission and cleaning functions of the device are only three points: first, to meet the requirement of continuous rotation of the rotating shaft 212 during the transmission process; second, to ensure the stationary state of the steam generator 110; and third, to achieve a sealed connection between the two during the execution of the softening action, so as to guide the hot steam to the preset position for ejection.

[0024] Those skilled in the art will understand that the shaft 212 of the screw drive mechanism needs to remain rotating during transmission, while the steam generator 110, due to size and weight limitations, must remain stationary. The connection structure between the stationary component (steam generator 110) and the rotating component (shaft 212) within a specific program segment, and how to achieve a sealed connection during the softening process, are conventional technical means in the art.

[0025] Specifically, those skilled in the art can easily implement this based on existing technical common sense, such as using a rotary joint 219 or a detachable sealed connection (sealed connection during softening, disconnected during transmission). There are various choices of such connection methods, all aiming to meet the functional requirement of "sealed connection during softening," and there is no need to exhaustively list them in this application. Those skilled in the art can obtain a clear and complete technical solution based on common knowledge and existing technology, implement this application, and solve the technical problem to be solved by this application. Therefore, the specific connection method between the two is not a necessary technical means to solve the technical problem to be solved by this application, and this application does not need to limit the specific connection method between the two.

[0026] This application adds friction cleaning components to the facial cleansing machine. During cleaning, several friction cleaning components are first placed in the empty cleansing chamber 310, and cleaning solution (such as water) is added depending on the situation. Water and friction cleaning components can be added simultaneously, and the residue fragments rubbed off are directly carried away by the water flow; alternatively, the friction cleaning components can be used for solid friction first, and then rinsed away with water after the friction is complete, depending on the user's habits and cleaning plan. At this time, the friction cleaning components are in direct contact with the spiral blades 213, and the rotation of the spiral blades 213 by starting the rotary drive can transport the friction cleaning components as "materials".

[0027] When the helical blade 213 rotates, its helix angle decomposes the force exerted by the blade on the material into an axial pushing force and a radial component. The radial component drives the material to slide relative to the blade's inclined surface, while the blade wall provides reverse support to the material. The relative motion between the two generates continuous friction, and the residue is carried away by this frictional force. For stubborn residues, the rotational speed can be increased, which will correspondingly increase the radial component and simultaneously intensify the friction between the material and the blade surface. When residual paste adheres to the blade surface, it is usually in a solidified or semi-solidified state, with intermolecular forces and mechanical interlocking forces between it and the blade, forming a stable adhesion structure. When the friction component and the blade experience intense friction, the mechanical shear force generated by their relative motion can directly act on the residual paste. This shear force can overcome the adhesion force between the paste and the blade surface, disrupting the interface between the paste and the blade, causing the paste to initially peel off from the blade surface.

[0028] The grinding effect accompanying intense friction can create microscopic cutting and breaking action on the residual paste: the raised structure or rough texture on the surface of the friction cleaning part will physically scrape and grind the paste layer on the blade surface, decomposing the blocky and layered residual paste into fine particles, reducing the structural integrity of the paste itself, and further weakening its adhesion stability on the blade surface.

[0029] The localized kinetic energy and heat generated by friction can help improve the cleaning effect: on the one hand, kinetic energy is transferred to the residual paste, reducing the cohesive force between its particles and making it easier to detach from the blade surface; on the other hand, a small amount of frictional heat can soften some of the stubborn paste, reducing its adhesion to the blade surface. Ultimately, under the synergistic effect of shear force, grinding force, kinetic energy, and heat energy, the residual paste is continuously peeled off, broken up, and discharged with the materials or cleaning fluid during the friction process, achieving effective removal of residual paste from the blade surface.

[0030] Furthermore, the centrifugal inertial force generated by the blade rotation gives the material a tendency to detach from the blade's working surface. When the centrifugal force exceeds the adhesion between the material and the blade, the material is thrown off the current blade, falls under gravity, and directly impacts the blade wall of the adjacent blade ring. This impact process creates contact with impact force, and after the impact, the material is caught by the blade wall and continues to move with the blade, re-entering the "sliding friction - throwing - impact" cycle, achieving high-frequency and intense contact between the material and the blade. This intense contact enhances the intensity of friction, which is beneficial for the friction cleaning components to remove and carry away the paste on the blade.

[0031] The limited space inside the conveying chamber causes several friction cleaning components to squeeze against each other and the chamber wall. The continuous rotation of the blades pushes the squeezed material back to the working surface of the blades, causing the friction cleaning components to repeatedly perform the "clamping-adhesion-sliding" action between the blades and the chamber wall. This further enhances the contact frequency and friction intensity between the friction cleaning components and the blades, which is beneficial for the friction cleaning components to remove and carry away the paste on the blades.

[0032] Furthermore, if residual paste adheres to the blade surface and is not cleaned promptly for various reasons, it will solidify, becoming a stable, dried paste adhering to the blade. Although increasing the rotation speed to enhance friction can also achieve a cleaning effect, violent impacts will shorten the equipment's lifespan. This application utilizes a steam generator 110 to rapidly absorb water and swell the starch, gluten, and other components in the residue, making their structure loose and effectively reducing the adhesion between the residue and the surface of the spiral blade 213. On one hand, when the hot steam comes into contact with the spiral blade 213 and the residual paste, which are below their saturation temperature, it will rapidly condense and release latent heat. The resulting condensate can directly penetrate into the pores inside the paste, achieving thorough wetting of the dried paste and breaking down the tight bond between starch and gluten molecules. The dried paste contains tiny pores (such as gaps between starch granules and micropores in the gluten network) and has a dense structure. When the hot steam comes into contact with the dried paste, it will instantly condense on its surface and at the pore inlets 216, forming tiny condensate droplets. These droplets, small in size and with surface tension matching the pore size, can more easily enter the micropores of the dried slurry. This avoids the formation of a "water film" on the slurry surface due to the large volume and surface tension of the droplets, as is the case with direct water rinsing, where most of the water flows only along the surface and cannot penetrate the interior. On the other hand, the heat released by the steam is conducted to the dried slurry through the condensate, accelerating the thermal motion of the slurry molecules and causing slight relaxation in the originally tightly bound slurry, resulting in a slight expansion of the internal pores. This is equivalent to widening the penetration channels for the condensate, reducing the structural resistance to water penetration, improving penetration efficiency, and further weakening the stability of its solidified form, causing the slurry to change from a dried state to a loose and softened state. Under the synergistic effect of the thermal effect and the wetting effect of the condensate penetration, the interfacial adhesion between the slurry and the blade surface is significantly reduced, creating conditions for subsequent removal of residues through friction, rinsing, and other methods.

[0033] This application uses a steam generator 110 as a source of hot steam to deliver hot steam from the preset cavity 215 of the rotating shaft 212 to the blades inside the washing chamber 310. The continuous supply of hot steam serves as a power source, opening the normally closed pneumatic valve of the outlet 217. The hot steam diffuses within the washing chamber 310, contacting the adjacent two rings of blade walls on the spiral blades 213 where the outlet 217 is located, softening the dough paste adhering to them and reducing the difficulty of scrubbing and rinsing.

[0034] This application does not specifically limit whether the washing chamber 310 of the dough washing machine can form a sealed chamber during softening. If the washing chamber 310 can close all openings except for the outlet 217 during the softening process, the softening effect will be improved. However, even if the washing chamber 310 cannot be closed and has an opening to the environment, apart from the initial movement of the hot steam along the initial ejection speed and the brief rise due to density difference, in the windless open environment of the washing chamber 310, most of the movement is a slow and uniform diffusion in all directions. Because the initial ejection position is near the helical surface of the blades, this free diffusion of heat exchange and condensation mainly acts on the blades, softening the dough paste adhering to the blades. Regardless of whether the washing chamber 310 is closed or not, the diffusion of hot steam will inevitably occur mainly on the helical surface of the blades, enabling heat exchange and condensate penetration with the residue on the helical surface, softening the residue and reducing the difficulty of rinsing and scrubbing.

[0035] When the high-temperature hot steam is first output, a large amount of condensate is generated during the heat exchange between the rotating shaft 212 and the steam. To reduce the risk of water hammer, this application adds a drain valve 218 to the preset cavity 215 to drain the condensate. This application does not limit the specific structure of the preset cavity 215 or the drain valve 218, as long as the water can be drained.

[0036] This application does not limit the specific structure of the normally closed pneumatic valve, as long as it can achieve the following: normally closed to seal the fluid passage 217; open when driven by gas (hot steam in this solution), allowing gas to pass through outlet 217; and reset closed when the gas driving force is lost. As is well known, the most basic function of a normally closed pneumatic valve is to close when there is no gas, open pneumatically, and reset closed when the pneumatic driving force is lost, ensuring a complete seal of the fluid passage when the pneumatic valve closes; this is not necessary to elaborate on here. During washing, the steam generator 110 does not supply hot steam, at which time the normally closed pneumatic valve is closed, outlet 217 is sealed, and material will not leak into the preset chamber 215. During softening, there is no material in the washing chamber 310, and residues are fixed on the blade wall. Free solid residues can be rinsed off before softening, and the valve can be allowed to dry or wiped dry before softening.

[0037] During the softening process, the steam generator 110 continuously supplies positive gas to the normally closed pneumatic valve. The gas pressure stably overcomes the valve's closing force, keeping the valve open. At this time, the gas pressure on the gas source side is always higher than that on the washbasin 310 side, forming a stable positive pressure difference. This pressure difference drives the gas to flow unidirectionally and continuously towards the washbasin 310, resulting in a continuous unidirectional airflow dominated by the pressure difference at the outlet 217. The liquid from the condensate in the washbasin 310 lacks sufficient kinetic energy to overcome the positive flow kinetic energy formed by the positive pressure difference at the outlet 217 and instead permeates in the reverse direction into the preset chamber 215.

[0038] Regarding the risk of condensate backflow into the preset chamber 215 during the resetting process of the pneumatic valve after the steam generator 110 stops supplying steam, this application argues that most of the condensate will flow along the curved surface of the rotating shaft 212. Without a guiding structure, only a small amount of condensate will have contact with the outlet 217, and even if backflow occurs, it will be brief and minimal. However, the risk of microbial growth due to accumulated liquid can be reduced by periodically opening the drain valve 218. Furthermore, after softening, the normally closed pneumatic valve isolates the preset chamber 215 from the washing chamber 310. When reconnected, the preset chamber 215 will become a passageway for hot steam. High-temperature steam has a sterilizing effect, and any microorganisms present will be directly killed by the high temperature of the steam. Therefore, compared to existing technologies, this application reduces the risk of microbial growth in the spiral blades 213 that directly contact the food, and effectively controls the risk of microbial growth due to seepage and accumulated liquid, ensuring the hygiene and safety of the food processing process and improving the overall food safety compliance and operational reliability of the equipment.

[0039] In one possible implementation, the normally closed pneumatic valve is a spring-loaded normally closed pneumatic valve that automatically closes the moment the steam generator 110 stops supplying steam, preventing condensate from seeping into the preset chamber 215 during the reset process. The inlet 216 of the rotating shaft 212 is detachably and sealingly connected to the rotating end of the rotary joint 219, for example, through a threaded connection with a sealing ring between the internal and external threads, or the inlet 216 is directly and detachably connected to the output end of the steam generator 110. The valve body of the steam trap 218 is detachably and sealingly connected to the opening of the steam trap 218 on the rotating shaft 212, for example, through a threaded connection with a sealing ring or a flange connection. The size of the inlet 216 and the inner diameter of the preset chamber 215 are increased to facilitate physical cleaning of seepage. For example, the preset chamber 215 extends axially along the rotating shaft 212, exhibiting a cylindrical shape (the cylindrical shape is similar to the cylindrical shape, ensuring that the steam trap 218 is at the lowest point and can drain water). The opening edge of inlet 216 coincides with the bottom edge of the cylinder of preset cavity 215, and their inner diameters are the same. The opening of steam trap 218 is located on the radial side wall of rotating shaft 212, and the opening direction is perpendicular to the cylindrical axis of preset cavity 215. When necessary, after removing steam trap 218, rotary joint 219 or steam generator 110, personnel can use a handle-equipped rod-shaped brush to rub the area, rinse with water, and let it air dry.

[0040] In one possible implementation, inlet 216 is equipped with a rotary joint 219, and the output end of steam generator 110 is connected to inlet 216 via rotary joint 219. Rotary joint 219 is a sealing device connecting a rotating component and a stationary component. Its core function is to achieve continuous and leak-free delivery of fluid (hot steam output from steam generator 110) when the two rotate relative to each other, while preventing damage to the connecting pipe due to rotation. The rotating end of rotary joint 219 is connected to the rotating component, inlet 216, of the rotating shaft 212, and the stationary end of rotary joint 219 is connected to the output end of steam generator 110. The sealing performance of the connection structure is achieved by a sealing component (such as a sealing ring mechanical seal, packing seal, etc.) located between the rotating end and the stationary end, which can adapt to the relative rotation of the rotating end and the stationary end, to prevent fluid leakage. This is the core of the inherent structure and connection logic of rotary joint 219, a technical means that is known, mastered, and clearly implemented by those skilled in the art, and will not be elaborated here. Throughout the entire operation, the inlet 216 of the rotating shaft 212 and the output end of the steam generator 110 remain connected. The steam generator 110 and the preset chamber 215 of the rotating shaft 212 maintain a sealed connection. During the washing or cleaning process, the rotating shaft 212 rotates naturally without damaging the connecting pipes of the stationary steam generator 110.

[0041] In another possible implementation, the inlet 216 of the preset cavity 215 of the rotating shaft 212 is detachably and sealed to the output end of the steam generator 110. When washing or friction cleaning is required, the connection between the inlet 216 of the preset cavity 215 of the rotating shaft 212 and the output end of the steam generator 110 is disconnected, allowing the rotating shaft 212 to rotate freely while the steam generator 110 remains stationary. When softening hot steam is required, the inlet 216 of the preset cavity 215 of the rotating shaft 212 is connected to the output end of the steam generator 110, achieving a sealed connection between the preset cavity 215 and the steam generation cavity, thus completing the flow guidance. Regarding the specific structure of the detachable connection, various connection methods can be chosen, all aiming to meet the functional requirements of detachability and sealed connection between the two chambers, and need not be exhaustively described in this application. Specifically, a flange connection with a sealing ring can be used to achieve the detachable connection, or the two can be threaded together, with a sealing ring added between the internal and external threads. The elastic deformation of the sealing ring fills the gap at the connection, ensuring a tight seal.

[0042] In one possible implementation, several outlets 217 are located on a first straight line, parallel to the axis of the rotating shaft 212. Preferably, the opening of the steam trap 218 is also located on the first straight line. The rotating shaft 212 is horizontally positioned. During softening, the rotating shaft 212 is adjusted so that the straight line is located at the lowest point of the rotating shaft 212 along the direction of gravity. The outlets 217 are located on the radial sidewall of the rotating shaft 212, with their opening direction along the radial direction of the rotating shaft 212. The initial velocity of the ejected hot steam moves downwards along gravity to contact the blades, and due to the density difference between the hot steam and room temperature air, it diffuses upwards, maximizing the contact opportunity between the blade wall and the hot steam. For example, all outlets 217 are in a group, and all outlets 217 are located on the first straight line, such as... Figure 2 As shown. Preferably, the outlets 217 are divided into two or more groups, each group including two or more outlets 217. All outlets 217 in one group are located on a first straight line, and the other group is located on a second straight line. Several outlets 217 in each group are located on a corresponding straight line, a third straight line, a fourth straight line, and so on. The two or more straight lines corresponding to the two or more groups of outlets 217 are parallel to each other and distributed circumferentially around the axis of rotation 212.

[0043] In another possible implementation, all outlets 217 are located on the first helix, and the helix of the helical blade 213 is the second helix. The first and second helical lines together constitute a double-helix. As two helical lines of the double-helix, the first and second helical lines are coaxial, parallel to each other, and equidistant along the axial direction. It should be noted that the core of the double-helix lies in two independent helical trajectories around the same axis. As long as the requirements of coaxiality, same direction of rotation, and equidistant distribution of the two helical trajectories are met, it is not necessary for them to be two solid helical convex structures on the same base (rotation shaft 212). Their physical forms can be diverse. It can be a solid structure of the convex helical blade 213, a solid structure of the concave helical groove, or a helical trajectory without a solid structure, such as the helical trajectory represented by the first helix involved in this application. The position of the opening of the drain valve 218 is random, with the principle of completing the drainage function and draining as much as possible.

[0044] In one possible implementation, the friction cleaning component is a food-grade abrasive, such as glass beads, ceramic beads, and stainless steel abrasive balls. The preferred friction cleaning component is a brush. The brush bristles have a certain surface roughness and basic hardness, preventing them from easily breaking. When the bristles contact the spiral surface of the spiral blade 213, the rough surface of the bristles increases the coefficient of friction between the contact surfaces. Simultaneously, the hardness ensures that the bristles can generate a certain normal pressure on the contact surface, thus increasing friction. The brush bristles are typically densely arranged, with tens to hundreds per square centimeter. Each bristle can form independent micro-friction with the contact surface. All bristles simultaneously engage in multi-point friction, and the superimposed frictional forces create a sufficiently strong overall frictional force. The bristles have a flexible structure and slightly bend upon contact with an object. This deformation allows the bristles to better conform to the micro-undulations of the contact surface, avoiding the problem of localized frictionlessness caused by non-contact with hard tools (such as the aforementioned abrasive), reducing cleaning dead zones, and resulting in better cleaning performance. The brush structure is not limited; it can be strip-shaped or the most conventional rod-shaped. Preferably, the brush bristles attach to the base (brush holder) without any handle or other protruding structures. Any necessary small protrusions on the base should be ground down as much as possible to reduce the risk of equipment damage caused by sharp protrusions violently impacting the equipment during the spiral conveying process. The rotation speed can also be appropriately reduced according to the collision situation during the conveying process to reduce the severity of the collision and reduce the risk.

[0045] In one possible implementation, the friction cleaning component is spherical, with its outer spherical periphery forming its friction structure. Further, the friction cleaning component is a brush. The rod-shaped bristles can be cut into a near-spherical structure. Preferably, a spherical brush 120 is directly used. Both hot-melt bristle implantation and drilling-in bristle implantation with adhesive processes support the spherical brush 120, with bristles arranged and attached in a spherical pattern. For example, bristles can be implanted using a spherical base via hot-melt implantation, or two hemispherical bases can be hot-melt-implanted and their cross-sections joined to form the spherical brush 120. Alternatively, hollow hemispherical bases can be drilled and implanted with adhesive, filled or unfilled, and then bonded together to form the spherical brush 120. The materials used should meet video safety requirements. Various methods can be chosen to achieve the spherical brush 120, aiming to meet the functional requirements of spherical bristle attachment, brush shape, and bristle arrangement; no exhaustive list is necessary in this application.

[0046] In one possible implementation, the screw drive mechanism is a reverse double screw conveyor mechanism. It utilizes two helical blades 213 that rotate in the same direction and at the same speed but in opposite directions to enhance friction. This not only increases the contact opportunities and washing intensity between materials during the conveying process in the washing procedure, thus improving the washing effect, but also increases the friction intensity of the friction cleaning components on the helical blades 213, thus improving the cleaning effect.

[0047] In one possible implementation, the rotary drive device 211 of the screw transmission mechanism is a reversible drive device. A reversible drive device means that the direction of rotation can be switched; it can drive the rotating shaft 212 to rotate clockwise or counterclockwise. The friction cleaning component is transported from the feed end of the washing chamber to the discharge end, the direction is changed, and then it is transported from the discharge end to the feed end of the washing chamber, and then reversed again to the discharge end. One input action completes several transport actions. During these multiple transports, the friction cleaning spiral blades 213 are cleaned, ensuring the cleaning effect. This eliminates the need to manually remove and re-insert the friction cleaning component after the one-way transport ends, making the operation simpler, the actions more continuous, and reducing time waste and manual labor intensity. The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0048] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
