Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a multi-stage cleaning and anti-adsorption cleaning production line for the bottom of a thermos cup and its cleaning method. Background Technology

[0002] In existing technologies, the cleaning process for stainless steel cups mainly relies on manual cleaning and ultrasonic cleaning machines. For example, the "Automatic Cleaning Device for Stainless Steel Cups" disclosed in Chinese Utility Model Patent CN212681958U presents the following: Manual cleaning suffers from high labor intensity and cumbersome procedures, particularly in terms of water consumption and wastewater discharge, which are detrimental to energy conservation and emission reduction. While ultrasonic cleaning machines have significant advantages in removing oil and dust, they cannot completely remove residual iron ions from the polishing sand on the inner and outer surfaces of stainless steel cups after brushing and polishing, failing to meet salt spray testing requirements. Regarding the cleaning of stainless steel cup lids, existing technologies, such as the "Ultrasonic Cleaning Device for Stainless Steel Cup Lids" disclosed in Chinese Utility Model Patent CN215613689U, primarily employ ultrasonic cleaning devices. These devices use a cleaning mechanism to load cleaning fluid, combined with a bottom ultrasonic generator and a water washing mechanism for subsequent cleaning. However, such devices mainly target the cleaning of single components and lack the ability to specifically handle complex structural components.

[0003] The main body of the thermos is welded together from the cup body and the cup bottom 01. Most cup bottoms 01 are designed according to... Figure 1 As shown, a thin sheet structure with flanges 011 is typically used, where the flanges 011 often employ a slightly open structure to meet functional requirements. However, this structural characteristic leads to the following technical problem during the cleaning process of the cup bottom 01: when two or more cup bottoms 01 are stacked concentrically in a transfer frame, a relatively sealed space is formed between the flanges 011. During stacking, handling, or transportation, when the cup bottoms 01 are subjected to external forces such as gravity, vibration, or manual handling, slight relative movements occur between the stacked cup bottoms 01, causing changes in the gas volume within the sealed space, resulting in a negative pressure phenomenon and a vacuum adsorption effect, making the cup bottoms 01 tightly adhered and difficult to separate. The stacking methods of the cup bottoms 01 are diverse, including forward stacking (the opening of the upper cup bottom 01 faces downward and the opening of the lower cup bottom 01 faces upward), reverse stacking (the bottom surfaces of the upper cup bottom 01 are in contact with the bottom surfaces of the lower cup bottom 01), and mixed stacking. Regardless of the stacking method, the negative pressure adsorption effect will prevent the cleaning liquid from penetrating into the contact surface between the cup bottoms 01, forming a cleaning dead zone in the adsorption area and affecting the cleaning effect. In addition to the micro-opening design of the flanged 011, cup bottoms with concave bottoms, cup bottoms with annular sealing edges, and other shapes and structures are also prone to similar negative pressure adsorption problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the prior art, the bottom of the thermos cup is prone to negative pressure adsorption due to stacking during the soaking and cleaning process, which makes it impossible for the cleaning liquid to fully contact the bottom surface of the cup, resulting in cleaning dead corners and affecting the cleaning effect and efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a multi-stage cleaning and anti-adsorption cleaning production line for the bottom of a thermos cup, comprising: a frame, a conveying mechanism installed on the frame, and a preliminary separation station, a peeling and refining station, and an intermittent quantitative collection station arranged sequentially along the conveying direction of the conveying mechanism, and a collection frame disposed in a cleaning tank for soaking the bottom of the cup for cleaning.

[0006] The conveying mechanism is equipped with a conveying unit for carrying the bottom of the cup and conveying it sequentially, ensuring the orderly transfer and positioning of the cup bottom during the processing.

[0007] The preliminary separation station uses a flexible separator to allow a single cup bottom to pass through, while multiple stacked cup bottoms are blocked, effectively achieving rough separation of the cup bottoms.

[0008] The peeling and refining station is equipped with an adaptive elastic peeling mechanism that applies mechanical separation force to the mutually adsorbed cup bottoms, overcomes the negative pressure adsorption force to achieve complete peeling, and ensures that all cup bottoms can be effectively separated.

[0009] The intermittent quantitative collection station includes a receiving guide frame and a quantitative settling structure. The quantitative settling structure includes a sliding channel, a channel outlet, and an intermittently closing door. The width of the channel inlet limits that only one cup bottom can enter the quantitative settling structure at a time, thereby achieving single cup bottom flow control.

[0010] The sliding channel is equipped with a guide ramp to form a dual positioning space, realizing the layered positioning of the two cup bottoms, which not only improves the collection efficiency but also ensures an appropriate distance between the cup bottoms.

[0011] The receiving guide frame is connected to a flow conveying component, which integrates functions such as driving the cup bottom to move, pre-rinsing, surface activation, and stain loosening, realizing an integrated design of power transmission and pretreatment.

[0012] In its implementation, the dual-positioning space includes a first positioning part and a second positioning part. The first positioning part protrudes outward from the outer side of the sliding channel through the shell wall, forming a groove-like structure lower than the second positioning part. The bottom wall of the second positioning part slopes downward from the right side wall of the sliding channel towards the first positioning part, and the bottom wall of the first positioning part slopes downward from the left side wall of the sliding channel towards the second positioning part. This design, through geometric configuration, achieves mechanical limiting and stable positioning of the two cup bottoms, ensuring the formation of a V-shaped angle and effectively preventing excessive overlap of the cup bottoms.

[0013] In terms of drive control, the intermittently closing door panel is driven by an electric hydraulic cylinder. The hydraulic drive method has the advantages of fast response speed and stable and reliable operation, and can control the opening and closing timing and movement range of the door panel to ensure the accuracy of quantitative dispensing at the bottom of the cup.

[0014] Regarding structural adjustment, an angle adjustment component, employing a cylinder structure, connects the quantitative straightening structure to the receiving guide frame. This angle adjustment function allows the device to adapt to storage frames of different sizes. By adjusting the corresponding position of the channel outlet within the storage frame, a rectangular arrangement of the cup bottoms within the frame is achieved, improving space utilization.

[0015] In terms of intelligent configuration, the flow assembly is equipped with a cleaning fluid preparation unit, which is connected to the cleaning tank via a proportional regulating valve. This unit can automatically prepare cleaning fluids of different concentrations based on the degree of contamination at the bottom of the cup. This intelligent cleaning fluid preparation function enables differentiated pretreatment, improves cleaning efficiency, and avoids waste of cleaning fluid.

[0016] Regarding temperature control, the flow assembly has a built-in temperature regulating device, using a PTC heating element to control the cleaning fluid temperature within the range of 40-80℃. The temperature control function employs different treatment temperatures for different types of stains: room temperature cleaning is suitable for standard mode, medium temperature cleaning accelerates the dissolution of grease stains, and high temperature cleaning treats stubborn stains, significantly improving the cleaning effect.

[0017] Regarding cleaning coverage, the nozzles of the flow assembly are arranged in two layers: the upper nozzle group sprays to clean the upper surface, and the lower nozzle group sprays to clean the lower surface. The flow assembly is equipped with a variable pressure pump to adjust the water flow pressure within the range of 0.2-2.5 MPa. The flow assembly is also equipped with a two-stage filtration and recovery system: a primary 200-mesh stainless steel filter and a secondary activated carbon adsorption layer. The multi-layer nozzle design ensures comprehensive cleaning coverage of the cup bottom, the variable pressure control allows for adjustment of cleaning intensity, and the two-stage filtration system ensures the recycling of water resources and the purification and regeneration of the cleaning solution.

[0018] The present invention also provides a cleaning method using the above-described apparatus, comprising the following steps: First, the cup bottoms to be processed are put into the preliminary separation station. The cup bottoms are carried forward by the conveying unit of the conveying mechanism. The flexible separator allows a single cup bottom to pass through while multiple stacked cup bottoms are intercepted, thus completing the preliminary separation. Then, the cup bottoms that have undergone preliminary separation are transported to the peeling and refining station. The adaptive elastic peeling mechanism applies mechanical separation force to the cup bottoms that are still mutually adsorbed, overcoming the negative pressure adsorption force to achieve complete peeling. Next, the effectively separated individual cup bottoms are transported to the intermittent quantitative collection station, where they are received by a receiving guide frame, and only one cup bottom is allowed to enter the quantitative settling structure through the channel inlet at a time. Subsequently, the cup bottom slides down into the dual positioning space within the sliding channel, achieving layered positioning of the two cup bottoms; Next, the flow assembly performs a comprehensive treatment on the bottom of the cup, including driving movement, pre-rinsing, surface activation, and loosening of stains. Then, the intermittently closed door panel opens, dropping a fixed amount of cup bottoms into the storage box, where the cup bottoms maintain a preset spacing. Finally, the bottoms of the cups are immersed in the cleaning tank. By maintaining an appropriate distance, negative pressure adsorption is avoided, ensuring that the bottom of each cup can fully contact the cleaning solution.

[0019] During the cleaning process, the flow assembly automatically adjusts the concentration of cleaning solution according to the degree of contamination at the bottom of the cup: 2-3% for light contamination, 5-8% for moderate contamination, and 10-12% for heavy contamination; at the same time, the temperature of the cleaning solution is controlled within the range of 40-80℃ to achieve personalized pretreatment results.

[0020] During the layered positioning process, after the first cup bottom slides down to the first positioning part and settles stably, its upper plane forms a V-shaped angle with the bottom wall of the second positioning part; when the second cup bottom slides down to the second positioning part, it is restricted to a limited space by the mechanical resistance of the upper part of the first cup bottom, thus achieving layered positioning of the two cup bottoms; during the delivery process, the limiting block of the intermittently closing door panel ensures that the two cup bottoms can be separated individually and fall into the storage box in sequence.

[0021] The beneficial effects of this invention are as follows: Effectively solves the problem of negative pressure adsorption: Through three-stage separation treatment (preliminary separation - peeling and refining - quantitative collection), it ensures that the bottom of the cup is effectively separated before soaking and cleaning, fundamentally avoiding the reformation of negative pressure adsorption and eliminating cleaning dead spots.

[0022] Significantly improves cleaning efficiency: Automated separation and collection processes replace manual sorting, increasing processing efficiency by 3-5 times; at the same time, pre-rinsing, surface activation and other pre-treatment functions shorten the subsequent soaking and cleaning time by 30-50%.

[0023] Intelligent differential cleaning: The concentration and temperature of the cleaning solution are automatically adjusted according to the degree of contamination, which ensures the cleaning effect while avoiding the waste of resources caused by over-cleaning.

[0024] Ensuring consistent cleaning quality: Quantitative control and spacing maintenance mechanisms ensure that each cup bottom receives sufficient and uniform contact with the cleaning solution, thus improving the consistency of cleaning quality.

[0025] Save on labor costs: Fully automated processing reduces the need for manual intervention, lowers labor intensity, and significantly reduces the demand for manpower.

[0026] Environmentally friendly and energy-saving: The water resource recycling system realizes the purification and regeneration of the cleaning solution.

[0027] High adaptability: Multiple adjustment mechanisms enable the device to adapt to the bottoms of insulated cups of different sizes and shapes, as well as storage frames of different capacities, resulting in high equipment utilization.

[0028] Stable and reliable operation: The application of mature technologies such as electric hydraulic drive and cylinder adjustment ensures the long-term stable operation of the equipment.

[0029] Through the above technical solution, the present invention effectively solves the problem of negative pressure adsorption in the cleaning of the bottom of thermos cups, and realizes efficient, intelligent and environmentally friendly automated cleaning treatment, which has important practical value and promotion prospects.

Detailed Implementation

[0032] Example 1: refer to Figures 1-2 This embodiment provides an automated separation and anti-adsorption cleaning device for the bottom of a thermos cup.

[0033] The device processes the following objects: Figure 1 The bottom 01 of the thermos shown is designed to address the separation problem during the cleaning process, taking into account the structural characteristics and adsorption properties of this type of bottom.

[0034] refer to Figure 2 As shown, the overall structure of the device includes a frame 10, on which a conveying mechanism 20 is mounted. Three functional areas are sequentially arranged along the conveying direction of the conveying mechanism 20: a preliminary separation station 30, a stripping and refining station 40, and an intermittent quantitative collection station 50. The stripping and refining station 40 is located above the conveying mechanism 20, while the preliminary separation station 30 and the intermittent quantitative collection station 50 are located at the beginning and end of the conveying mechanism 20, respectively.

[0035] The storage frame 02 is placed in the cleaning tank 03, with its edges resting on the tank wall. The main body of the device is placed on the ground next to the cleaning tank 03 and moves along a ground track via rollers. The cup bottoms 01 are conveyed by the conveying mechanism 20, processed sequentially through each functional station, and finally arranged in an orderly manner in the storage frame 02 while maintaining a preset spacing.

[0036] With the above structural configuration, the device can effectively separate the cup bottoms 01 and ensure that each cup bottom 01 can fully contact the cleaning liquid during soaking and cleaning, avoiding cleaning dead corners caused by overlapping and forming a closed space.

[0037] The system workflow is mainly divided into three stages: Phase 1: Preliminary Separation. The bottom of the thermos cup 01 is roughly separated at the preliminary separation station 30, which disperses the clumps of cup bottom 01 as much as possible and distributes them individually on the conveying mechanism 20, and then conveys them to the next station.

[0038] The second stage: peeling and refining. Due to the strong negative pressure adsorption force formed between some cup bottoms 01, they cannot be effectively separated at the preliminary separation station 30. These cup bottoms 01 that are still adsorbed to each other are transported to the peeling and refining station 40. At this station, a peeling mechanism applies mechanical separation force to the adsorbed cup bottoms 01, overcoming the negative pressure adsorption force to achieve complete peeling.

[0039] The third stage: quantitative collection. After being processed in the first two stations, the individual cup bottoms 01 that have been effectively separated are transported to the intermittent quantitative collection station 50. As the core functional part of this device, this station uses an intermittent control mechanism to sequentially and orderly place the cup bottoms 01 into the collection frame 02 in a preset quantity (two at a time), ensuring that the cup bottoms 01 maintain an appropriate spacing within the collection frame 02, and preventing the re-formation of negative pressure adsorption during subsequent cleaning and soaking processes.

[0040] refer to Figures 3-4 The conveying mechanism 20 adopts a transmission chain design and includes three key components that transmit power sequentially along the power transmission direction: a conveying drive component 21, a conveying timing belt 22, and a rubber conveyor belt 23.

[0041] In one basic implementation, the rubber conveyor belt 23 is capable of carrying the cup bottom 01 and transporting it from one station to the next, thereby achieving continuous transmission of the cup bottom 01.

[0042] Furthermore, to prevent the cup bottom 01 from shifting or overlapping during transport, the rubber conveyor belt 23 is equipped with equally spaced isolation plates 231, forming multiple conveying units 24. The width of each conveying unit 24 is designed to be slightly larger than the diameter of the cup bottom 01, ensuring that the cup bottom 01 can be individually and neatly positioned in each conveying unit 24.

[0043] Preferably, the height and shape of the isolation plate 231 are designed to effectively separate adjacent cup bottoms 01, preventing them from contacting each other and re-adhering due to vibration or inertia during transportation, while also preventing scratches or deformation damage to the surface of the cup bottoms 01.

[0044] refer to Figures 3-4 The initial separation station 30 is located at the beginning of the system, serving not only as the first processing station of the system, but also as the loading area for holding the bottom of the cup 01 to be processed.

[0045] In terms of basic structure, this workstation consists of two main components: a enclosure frame 31 and a flexible separator 32. The enclosure frame 31 adopts a three-sided enclosed design, surrounding the starting point of the rubber conveyor belt 23 to form a semi-enclosed receiving space for storing the cup bottoms 01 to be separated.

[0046] Furthermore, the flexible separator 32 is installed between the two opposing inner walls of the enclosure frame 31, with its installation direction perpendicular to the conveying direction of the rubber conveyor belt 23, forming a flexible barrier within the accommodating space. The flexible separator 32 is made of rubber and has moderate elasticity and toughness, enabling it to deform appropriately under external force and then return to its original shape.

[0047] More preferably, the lower end of the flexible separator 32 is configured to be flush with or slightly higher than the upper end of the conveying unit 24. This positioning allows a single cup bottom 01 located within the conveying unit 24 to push against the flexible separator 32 to produce local deformation and pass through smoothly, while multiple cup bottoms 01 stacked above the partition plate 231 are effectively intercepted.

[0048] Further optimized, the lower part of the flexible separator 32 has multiple partition strip holes (such as... Figure 4 (As shown by the densely packed lines). These strip-shaped holes significantly reduce the local stiffness of the flexible separator 32, making it easier to undergo moderate deformation under the pressure of the cup bottom 01, thereby improving the efficiency and reliability of the initial separation.

[0049] In terms of working principle, the initial separation station 30 achieves a "dropping and blocking" separation mechanism through the coordinated cooperation of the flexible separator 32 and the conveying unit 24: when the group of cup bottoms 01 moves forward under the drive of the rubber conveyor belt 23, the individual cup bottoms 01 already located in the conveying unit 24, because their height is lower than the lower edge of the flexible separator 32, can push the flexible separator 32 to undergo local deformation and pass through from below, continuing to be conveyed to the next station; while the cup bottoms 01 located above the isolation plate 231 or stacked on top of each other are intercepted by the flexible separator 32 and fall back into the loading area, waiting for the next separation opportunity. Through the continuous movement of the conveyor belt, the entire batch of cup bottoms 01 is gradually dispersed and individually distributed to each conveying unit 24.

[0050] refer to Figures 3-4 After initial separation, the bottom of the cup 01 enters the stripping and refining stage 40 for further separation.

[0051] In terms of basic structure, the core of this station is the adaptive elastic peeling mechanism 41, which is specifically used to handle the adsorption cup bottom 01 that failed to be effectively separated at the preliminary separation station 30. The adaptive elastic peeling mechanism 41 includes a mounting frame 411 connected to the frame 10, and a reverse track peeling structure 412 connected to the mounting frame 411.

[0052] Furthermore, the reverse track stripping structure 412 adopts a reverse motion design, including a reverse-movement drive component 4121 that transmits power sequentially along the power transmission direction, a reverse-movement synchronous belt 4122, and a reverse track 4123. Multiple rows of stripping brushes 4124 are evenly spaced on the reverse track 4123; their material and rigidity design ensures effective contact with the cup bottom 01 without causing surface scratch damage.

[0053] The reverse conveyor belt 4123 operates in the opposite direction to the rubber conveyor belt 23, creating opposing forces in the contact area. When the bottom of the adsorption cup 01 above the conveying unit 24 comes into contact with the peeling brush 4124, a relative resistance force is generated between them. This resistance force is sufficient to overcome the negative pressure adsorption force, achieving forced separation of the cup bottom 01. The peeled upper cup bottom 01 is blocked and pushed back by the reverse conveyor belt until it falls into the subsequent empty conveying unit 24 for continued conveying, or is retrieved from the end of the device by the operator after batch processing.

[0054] In terms of adaptive design, this device can handle the bottoms of various sizes and shapes of insulated cups, employing a triple adaptive adjustment mechanism: First adjustment: The flexible separator 32 in the initial separation station 30 adopts an adjustable design. The inner wall of the enclosure frame 31 is provided with multi-level sliding tracks, and the flexible separator 32 can slide on the tracks and be locked in any position to achieve height and position adjustment to adapt to cup bottoms 01 of different sizes.

[0055] The second adjustment: The peeling and refining station 40 is equipped with an elastic adaptation component 413. This component has four sets of rectangularly distributed elastic units, each set including a connecting pin 4131 and a coaxially mounted adaptation spring 4132. The lower end of the connecting pin 4131 passes through the mounting frame 411 and is connected to the reverse track peeling structure 412 through the connecting frame 415. The adaptation spring 4132 is located between the mounting frame 411 and the head of the connecting pin 4131. When cup bottoms 01 of different heights enter the station, the peeling structure 412 can automatically adjust its vertical position under the action of the spring: the cup bottom 01 with a larger height will push the peeling structure 412 upward and compress the adaptation spring 4132. After the cup bottom 01 passes, the spring recovers and resets the peeling structure 412. This passive adaptation mechanism ensures effective handling of cup bottoms 01 of different heights.

[0056] The third adjustment: The system is equipped with an active height adjustment component 414, which uses a cylinder structure and is connected to the upper end of the mounting bracket 411 via a connecting plate. The operator can control the cylinder's extension and retraction to drive the entire adaptive elastic peeling mechanism 41 to make vertical displacement, adjusting the distance between the reverse track peeling structure 412 and the rubber conveyor belt 23. This active adjustment mechanism works in conjunction with the elastic adaptation component 413 to further improve the device's adaptability to cup bottoms of different sizes 01.

[0057] Reference Figure 3 , Figures 5-9 after preliminary separation and stripping treatment, the cup bottom 01 enters the key link of the present apparatus: the intermittent quantitative collection station 50. As the technical core of the entire system, this station solves the problems of quantitative collection and anti-overlapping arrangement of the cup bottoms 01.

[0058] The basic technical solution includes: First, the basic collection structure. The intermittent quantitative collection station 50 includes a receiving guide frame 51 and a quantitative sorting structure 52. The receiving guide frame 51 is butted with the conveying terminal of the rubber conveyor belt 23, so as to receive the single cup bottom 01 output from the conveying mechanism 20; the quantitative sorting structure 52 is communicated with the receiving guide frame 51, and is responsible for the quantitative collection and output of the cup bottoms 01.

[0059] Second, the single cup bottom flow control mechanism. A channel inlet 511 is provided at the connection between the receiving guide frame 51 and the quantitative sorting structure 52, and the width W1 of the channel inlet 511 satisfies: D<W1<2D (where D is the diameter of the cup bottom 01). This size limitation ensures that only one cup bottom 01 can enter the quantitative sorting structure 52 from the receiving guide frame 51 at a time, preventing multiple cup bottoms from entering simultaneously.

[0060] Third, the quantitative collection channel. The quantitative sorting structure 52 includes a sliding channel 521 and a channel outlet 522, and the entered single cup bottom 01 slides down to the channel outlet 522 under the action of gravity to wait for output.

[0061] Fourth, the intermittent control mechanism. The channel outlet 522 is provided with an intermittent closing door plate 523, and the quantitative output of the cup bottoms 01 is realized by controlling the opening and closing of the door plate 523. When the door plate 523 is closed, the cup bottoms 01 accumulate in the sliding channel 521; when the door plate 523 is opened, the accumulated cup bottoms 01 are sequentially output into the storage frame 02.

[0062] The optimized and improved solution includes: Gravity assistance optimization. The receiving guide frame 51 adopts a trapezoidal structure and is arranged obliquely downward, with an inclination angle set to 15°-30°, and the gravity component is used to assist the cup bottom 01 to slide down smoothly. The guide frame includes a bottom plate and protective side plates on both sides, forming a closed sliding channel to prevent the cup bottom 01 from deviating from the track during the sliding process.

[0063] Sliding acceleration design. The inclination angle of the quantitative sorting structure 52 is larger than the inclination angle of the receiving guide frame 51, preferably 30°-45°, forming an angle turn at the channel inlet 511, which accelerates the sliding speed of the cup bottom 01 toward the channel outlet 522 and improves the collection efficiency.

[0064] Double-bottom collection mechanism. Due to the width limitation of the sliding channel 521, when the first cup bottom 01 slides down to the closed door 523 of the channel outlet 522, the second cup bottom 01 enters the sliding channel 521 and forms a partially stacked double-bottom combination with the first cup bottom 01. At this time, opening the door 523 allows both cup bottoms 01 to be output at once, maintaining a preset distance between them, which improves storage efficiency and prevents the reformation of negative pressure adsorption.

[0065] Control system. The intermittently closing door panel 523 is driven by an electric hydraulic cylinder 5231, and a hinged linkage plate is set between the hydraulic cylinder and the door panel to achieve control. The system can control the timing and duration of the door panel opening and closing according to the capacity of the storage frame 02 and the processing rhythm of the cup bottom 01, so as to achieve better collection efficiency.

[0066] Connection method optimization. The quantitative straightening structure 52 is connected to the receiving guide frame 51 via a rotating hinge, allowing for fine adjustment of the tilt angle according to the characteristics of cup bottoms 01 of different specifications, thereby improving system adaptability.

[0067] Further, the positioning mechanism design. (See reference) Figures 5-6 To ensure the cup bottom 01 is positioned within the dual-positioning space, the structure of the sliding channel 521 has been specially optimized. One side wall of the sliding channel 521 is provided with a guide ramp 524 that slopes towards the channel outlet 522. The guide ramp 524 and the other side wall form a limiting channel 526, the width of which only allows a single cup bottom 01 to pass through.

[0068] Specifically, the dual-positioning space 525 is constructed as follows: A dual-positioning space 525 is formed between the guide ramp 524 and the channel outlet 522, which can accommodate two cup bottoms 01. This space includes a first positioning part 5251 and a second positioning part 5252. The limiting channel 526 is located above the second positioning part 5252, serving as the only passageway for the cup bottoms 01 to enter this space. The side of the first positioning part 5251 closest to the second positioning part 5252 has a relatively large and higher space, and its bottom wall is inclined relative to the upper wall rather than parallel. The second positioning part 5252 is adjacent to and higher than the first positioning part 5251. The two positioning parts serve as the final stable positioning positions for the two cup bottoms 01, respectively.

[0069] Furthermore, an inclined guide design is employed. The bottom edge of the second positioning part 5252 is inclined downwards from the right side wall of the sliding channel 521 towards the first positioning part 5251, and the bottom edge of the first positioning part 5251 is inclined downwards from the left side wall of the sliding channel 521 towards the second positioning part 5252. The channel outlet 522 is also inclined, as shown in the reference section. Figure 9Viewed from an angle parallel to the large surface of the quantitative straightening structure 52, the channel outlet 522 is inclined at 4°-6° relative to the horizontal plane. This inclined design, on the one hand, utilizes the gravitational component generated by the inclined angle to assist the cup bottom 01 in a stable position at the channel outlet 522, preventing the cup bottom 01 from getting stuck or jammed at the outlet; on the other hand, it helps the cup bottom 01 to form a stable relative position within the dual positioning space 525, creating favorable conditions for subsequent dual cup bottom positioning. After the cup bottom 01 passes through the limiting channel 526 and falls to the second positioning part 5252, it will slide along its inclined bottom edge to the first positioning part 5251 and be confined therein. At the same time, through the action of the inclined bottom edge, the upper plane of the cup bottom 01 after it is stably positioned in the first positioning part 5251 forms a V-shaped angle with the bottom edge of the second positioning part 5252.

[0070] The key mechanical limiting mechanism is as follows: when the first cup bottom 01 slides down to the second positioning part 5252, since the upper plane of the first cup bottom 01 and the bottom wall of the second positioning part 5252 form a V-shaped angle, the movement of the second cup bottom 01 towards the first positioning part 5251 will be mechanically resisted by the upper end of the first cup bottom 01. This resisting action restricts the second cup bottom 01 within the limited space between the side wall of the first positioning part 5251 and the first cup bottom 01, preventing the second cup bottom 01 from continuing to penetrate deeper into the first positioning part 5251, thereby achieving layered positioning and stable placement of the two cup bottoms 01. This mechanical limiting design ensures that the two cup bottoms 01 maintain an appropriate relative position, which is convenient for simultaneous removal and avoids jamming problems caused by excessive overlap.

[0071] In terms of space optimization design, the two cup bottoms 01 are placed in a partially overlapping manner, which not only realizes the function of outputting two cup bottoms 01 at one time, but also avoids the quantitative sorting structure 52 being too large, ensuring that the device has sufficient room to move within the storage frame 02, without affecting the final storage and sorting effect.

[0072] Angle adjustment mechanism. For example... Figure 7 As shown, an angle adjustment component 527 is connected between the quantitative straightening structure 52 and the receiving guide frame 51. This component adopts a cylinder structure to drive the quantitative straightening structure 52 to rotate, adjust the corresponding position of the channel outlet 522 in the storage frame 02, and realize the rectangular arrangement of the cup bottom 01 in the storage frame 02.

[0073] Timing control mechanism. (See reference) Figures 5-7 This device utilizes the difference in friction during the sliding process of the cup bottom 01 to achieve timing control. A rubber sheet 61 is embedded at the channel entrance 511 (e.g., Figure 6 As shown), increase the friction between the bottom of the cup 01 and the bottom of the cup 01, so that the bottom of the cup 01 is suspended at the entrance of the channel 511.

[0074] Furthermore, a water flow drive system. The receiving guide frame 51 is connected to a flow transmission assembly 62 (such as...). Figure 5 As shown, this component is intermittently controlled by the system. When the bottom of a cup 01 reaches the first positioning part 5251, the water conveying component 62 sprays water to flush the bottom of the cup 01 at the channel inlet 511 into the sliding channel 521; then the water spraying stops, allowing the bottom of the cup 01 in the sliding channel 521 to continue sliding to the channel outlet 522; the system controls the water conveying component 62 to spray water again, so that the bottoms of the cups 01 slide down one by one in an orderly manner.

[0075] The water supply assembly 62 integrates three major cleaning functions: pre-rinsing, surface activation, and stain loosening. It achieves comprehensive pre-treatment of the cup bottom 01 through water flow control. This assembly is equipped with a cleaning solution preparation unit, connected to the cleaning tank 03 via a proportional regulating valve. It automatically adjusts the concentration of cleaning solution according to the degree of contamination of the cup bottom 01; for example, a 2-3% concentration is used for light contamination, a 5-8% concentration for moderate contamination, and a 10-12% concentration for heavy contamination. It also has a built-in temperature control device, using a PTC heating element to maintain the cleaning solution temperature within the range of 40-80℃. Room temperature cleaning is suitable for standard mode, medium temperature cleaning accelerates the dissolution of grease stains, and high temperature cleaning treats stubborn stains.

[0076] The nozzles of the flow assembly 62 are arranged in two layers: the upper nozzle group sprays water to clean the upper surface, and the lower nozzle group sprays water to clean the lower surface, ensuring complete cleaning coverage of the cup bottom 01. The system is equipped with a variable pressure pump, which adjusts the water pressure within the range of 0.2-2.5MPa according to cleaning needs, and adopts pulse cleaning technology to achieve intermittent high-pressure water jet impact through a control valve.

[0077] The water flow drive system has a dual function: First, as a power system, it overcomes the frictional resistance between the cup bottom 01 and the rubber sheet 61 at the channel inlet 511 by controlling the impact force of the water flow, thereby realizing the timed release and orderly conveying of the cup bottom 01; Second, as a pre-cleaning system, it performs a preliminary rinse on the surface of the cup bottom 01 during its sliding process, removing dust, oil and other impurities that may have adhered during the production process, thus creating better initial conditions for subsequent soaking and cleaning.

[0078] Regarding water resource recycling, the water source for the conveying component 62 is directly taken from the cleaning tank 03, which not only realizes the recycling of the cleaning solution but also ensures that the water flow has a certain cleaning capacity. The component is equipped with a two-stage filtration and recovery system: the first stage uses a 200-mesh stainless steel filter to remove large particulate impurities, and the second stage uses an activated carbon adsorption layer to remove organic pollutants. The water flowing after rinsing the bottom of the cup 01 eventually flows back to the cleaning tank 03, mixes with the cleaning solution in the tank, and is purified and reused under the action of the circulating filtration system in the cleaning tank 03, forming a closed-loop water resource recycling system.

[0079] Regarding water flow parameter control, the water pressure, flow rate, and jet angle of the conveying component 62 can all be adjusted according to the weight and surface characteristics of different cup bottoms 01: for lighter or smoother cup bottoms 01, a lower water pressure is used to avoid excessive impact; for heavier or rougher cup bottoms 01, the water pressure is increased to ensure effective propulsion. Simultaneously, the water flow interval is synchronized with the overall system's operating rhythm to ensure the continuity and stability of the cup bottom 01's delivery.

[0080] Positioning Guarantee Mechanism. To further ensure the positioning of the cup bottom 01 in the second positioning part 5252, a limiting block 5232 is provided at one end of the intermittently closing door panel 523 relative to the sliding channel 521 (e.g., Figure 8 (As shown). When the intermittently closing door panel 523 is closed, the limiting block 5232 abuts against the outer wall of the cup bottom 01 in the second positioning part 5252, preventing the two cup bottoms 01 in the first positioning part 5251 and the second positioning part 5252 from falling out in a stuck state, ensuring that the two cup bottoms 01 can be separated and fall into the storage frame 02.

[0081] System coordination and control. To achieve coordination between the preliminary separation station 30, the stripping and refining station 40, and the intermittent quantitative collection station 50, the system controls the opening and closing time of the intermittent closing door 523, the intermittent start time of the conveyor assembly 62, and the intermittent conveying time of the conveyor belt to ensure that each station works in tandem.

[0082] The specific working process of this invention is as follows: Phase 1: Preliminary Separation Processing First, a batch of cup bottoms 01 that need to be separated and stored is poured into the enclosure frame 31 of the preliminary separation station 30. The conveyor mechanism 20 is started, and the rubber conveyor belt 23 moves the group of cup bottoms 01 towards the flexible separator 32. When the cup bottoms 01 reach the position of the flexible separator 32, the flexible separator 32 plays a key role of "lower placement and upper resistance": a single cup bottom 01 already located in the conveyor unit 24, because its height is lower than the lower edge of the flexible separator 32, can push the strip-shaped hole area of ​​the flexible separator 32 to produce local elastic deformation and pass smoothly from below; while multiple cup bottoms 01 located above the isolation plate 231 or stacked on top of each other are effectively intercepted by the flexible separator 32 and fall back into the loading area to wait for the next round of separation. Through the continuous operation of the conveyor belt and the repeated screening action of the flexible separator 32, the preliminary separation and individual distribution of the cup bottoms 01 are achieved.

[0083] Phase Two: Stripping and Refining Process After initial separation, the cup bottoms 01 continue to the peeling and refining station 40 via the conveyor belt. For a single cup bottom 01 that has been separated, it can smoothly pass through this station under the automatic adjustment of the elastic adaptation component 413 of the adaptive elastic peeling mechanism 41. For stacked cup bottoms 01 that still exhibit negative pressure adsorption, the reverse track peeling structure 412 begins to function. The reverse track 4123 operates in the opposite direction to the rubber conveyor belt 23. When the stacked cup bottoms 01 contact the peeling brush 4124, significant relative resistance and shear force are generated between them. This mechanical separation force is sufficient to overcome the negative pressure adsorption between the cup bottoms 01. The successfully peeled upper cup bottom 01 is blocked by the reverse track and pushed back into the subsequent empty conveying unit 24 to continue forward transport, while the lower cup bottom 01 remains within the original conveying unit 24 and continues to move forward normally, thus achieving complete peeling and separation of the stacked cup bottoms 01.

[0084] Phase 3: Quantitative Collection 3.1 Guided Receiving Process The effectively separated individual cup bottoms 01 travel along the conveyor belt to the conveyor terminal and fall naturally into the receiving guide frame 51. Under the action of gravity, the cup bottoms 01 slide along the inclined trapezoidal guide frame. Due to the frictional resistance generated by the rubber sheet 61 embedded in the channel entrance 511, the cup bottoms 01 will pause at the channel entrance 511, waiting for further control commands from the system.

[0085] 3.2 Water Flow Driven Control The system controls the flow delivery component 62 to start, spraying a constant-pressure water flow that impacts the cup bottom 01, which is paused at the channel inlet 511. This overcomes the frictional resistance of the rubber sheet 61, pushing the cup bottom 01 into the sliding channel 521. Simultaneously, the water flow pre-cleans the surface of the cup bottom 01, removing dust and oil residue accumulated during production. The system then shuts off the flow delivery component 62, and the next cup bottom 01 in the receiving guide frame 51 continues to slide and pauses at the channel inlet 511, awaiting the next round of water flow.

[0086] 3.3 Dual-positioning installation The cup bottom 01, entering the sliding channel 521, accelerates down the inclined angle and enters the dual positioning space 525 through the limiting channel 526. After passing through the limiting channel 526, the first cup bottom 01 falls to the second positioning part 5252, and then slides along its inclined bottom wall toward the first positioning part 5251, and is finally stably positioned in the groove-shaped first positioning part 5251, with its upper end plane forming a V-shaped angle with the bottom wall of the second positioning part 5252.

[0087] When the system restarts the flow assembly 62, the second cup bottom 01 is flushed into the sliding channel 521 and falls through the limiting channel 526 to the second positioning part 5252. Due to the mechanical resistance of the upper plane of the first cup bottom 01, the second cup bottom 01 is restricted to the limited space between the side wall of the first positioning part 5251 and the first cup bottom 01, and cannot continue to go deeper into the first positioning part 5251, thereby realizing the layered positioning and partial overlapping placement of the two cup bottoms 01.

[0088] 3.4 Quantitative Output Control After two cup bottoms 01 are placed in the dual-positioning placement space 525, the system controls the electric hydraulic cylinder 5231 to drive the intermittently closing door panel 523 to open. Simultaneously, the limiting block 5232 releases its restraint on the cup bottoms 01 in the second positioning part 5252, allowing the two partially stacked cup bottoms 01 to separate individually and fall simultaneously from the inclined channel outlet 522, accurately placing them into the predetermined position in the storage frame 02. The two cup bottoms 01 maintain an appropriate distance within the storage frame 02, preventing the reformation of negative pressure adsorption and improving storage efficiency.

[0089] 3.5 Loop Control Mechanism After the intermittently closing door panel 523 completes one open-output-close cycle, the system re-enters the waiting state. The angle adjustment component 527 adjusts the rotation angle of the quantitative straightening structure 52 according to the filling status of the storage box 02, changing the corresponding position of the channel outlet 522 in the storage box 02 to ensure that the cup bottoms 01 are arranged in a rectangular, orderly manner within the storage box 02. The system repeats the complete control process described in 3.1-3.4, continuously delivering two cup bottoms 01 with each intermittent door panel opening, until all cup bottoms 01 in the current batch have been separated and stored.

[0090] System Coordination and Effectiveness Assurance Throughout the entire process, the system coordinates and controls the timing of the flexible separation at the initial separation station 30, the reverse conveyor operation at the peeling and refining station 40, the door opening and closing time at the intermittent quantitative collection station 50, the intermittent water spraying time of the flow conveyor component 62, and the operating rhythm of the conveyor belt. This ensures seamless connection and efficient collaborative work among all stations. Ultimately, it achieves a complete transformation of the cup bottom 01 from a stacked adsorption state to an individually ordered arrangement, effectively solving the technical problem of cleaning dead zones caused by negative pressure adsorption during the soaking and cleaning process of the thermos cup bottom.

[0091] Example 2: This embodiment provides another technical solution for an automated separation and anti-adsorption cleaning device for the bottom of a thermos cup, achieving the same technical effect with a different mechanical structure.

[0092] Alternative implementation of the conveying mechanism The conveying mechanism 20 can adopt a roller chain conveying design, including a drive roller, a driven roller, and a connected endless conveying chain. Pallet-type conveying units (24) are fixed at equal intervals on the conveying chain. Each conveying unit includes a circular grooved bottom plate and a peripheral baffle for supporting and limiting the bottom of the cup 01.

[0093] Alternatively, the conveying mechanism 20 can also adopt a pneumatic conveying method, which uses intermittent injection of compressed air to push the cup bottom 01 to move along a preset track. The bottom of the conveying channel is provided with a guide groove to ensure that the cup bottom 01 maintains the correct orientation.

[0094] Alternative implementation methods for the initial separation station The initial separation station 30 can adopt a vibration screening separation mechanism, including a vibration separation table and a screening control component. The vibration separation table is equipped with positioning holes corresponding to the conveying unit 24. High-frequency micro-vibration is generated by the vibration motor, which causes the stacked cup bottoms 01 to gradually loosen and preferentially fall into the positioning holes, so as to achieve the effect of passing through a single cup bottom 01 while intercepting multiple cup bottoms 01.

[0095] Alternatively, a rotary centrifugal separation method can be used, which uses centrifugal force to disperse the cup bottom 01 along radial distribution grooves, with each distribution groove cross section accommodating only a single cup bottom 01 passing through.

[0096] Alternative implementation methods for stripping fine chemical properties The stripping and refining stage 40 can employ an airflow impact separation mechanism, including a high-pressure air pump, an airflow distributor, and a directional nozzle. A photoelectric sensor detects the stacking state of the cup bottoms 01. When multiple cup bottoms 01 are detected stacked, the directional nozzle ejects a high-pressure airflow that cuts into the side contact surface. The airflow impact force overcomes the negative pressure adsorption force, achieving separation.

[0097] Alternatively, ultrasonic separation technology can be used. An array of ultrasonic generators can be set up in the section where the conveying mechanism passes through the station. The high-frequency vibration generated by the ultrasonic waves weakens the negative pressure adsorption force between the bottom 01 of the cup, and separation can be achieved in conjunction with slight mechanical disturbance.

[0098] All of the above alternative implementation methods can achieve the same technical effect as Example 1, and are fully compatible with the intermittent quantitative collection station (50), forming different technical combination schemes.
