Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning machine for cleaning adhesive brushing tools. Background Technology

[0002] In the leather goods manufacturing industry, including footwear, bags, and toys, the bonding process is a crucial assembly step. This process typically requires operators to use brushes (such as bristle brushes or toothbrushes) to evenly apply specialized adhesive to the surfaces of the parts to be bonded. However, during use, a significant amount of adhesive inevitably remains on the brush bristles. This residual adhesive quickly hardens and clumps in the air, causing the bristles to harden, stick together, and lose elasticity, severely impacting the uniformity of subsequent application and product quality.

[0003] Currently, there are two main methods used in the industry to deal with brushes contaminated with cured adhesive:

[0004] 1. Direct Disposal and Replacement: This is the most common practice. When the glue on the brush accumulates to the point that it affects its use, the operator will simply discard it and replace it with a new brush. Although this method is simple and direct, it leads to a huge consumption of brushes. In the long run, this not only increases the company's production costs but also causes a serious waste of resources, which is inconsistent with the concept of green and environmentally friendly production.

[0005] 2. Manual Cleaning and Maintenance: Some companies attempt to clean brushes to save costs. The common practice is to soak the glue-stained brushes in water or specific organic solvents (such as ethyl acetate or acetone), and then have operators manually rub and scrape them. While this method extends the brush's lifespan to some extent, it has several significant drawbacks: First, it's inefficient, consuming considerable manpower and time; second, the cleaning effect is poor, as hardened adhesive residue is difficult to remove completely, affecting reusability; third, prolonged direct contact with chemical solvents poses potential health hazards to operators; and finally, volatile solvents can pollute the workshop environment and pose certain safety risks.

[0006] Therefore, existing methods fail to achieve a good balance between ensuring cleaning effectiveness, improving efficiency, and considering economic and environmental factors. The industry urgently needs specialized equipment that can automate and efficiently clean adhesive application tools to address these long-standing pain points. Utility Model Content

[0007] The main purpose of this invention is to propose a cleaning machine for cleaning adhesive application tools, aiming to achieve automated and efficient cleaning of adhesive application tools.

[0008] To achieve the above objectives, this utility model proposes a cleaning machine for cleaning adhesive application tools, comprising:

[0009] The frame has an internal working chamber for holding the cleaning fluid.

[0010] A cleaning mechanism is disposed within the working chamber. The cleaning mechanism includes a roller brush and a driving mechanism. The roller brush is rotatably mounted within the working chamber and is at least partially immersed in the cleaning liquid. The driving mechanism is disposed outside the frame and is used to drive the roller brush to roll.

[0011] A fixing mechanism is provided inside the working cavity, and the fixing mechanism includes a clamp and a positioning platform arranged vertically.

[0012] The positioning platform is provided with at least one positioning port for supporting the brush handle, so that when the brush is placed with the brush head facing down, the brush head of the brush hangs below the positioning port and is opposite to the roller brush.

[0013] The clamp has a movable actuator. When the actuator moves toward the clamping direction, it can push the brush handle of the brush, causing the brush head of the brush to swing from the initial vertical state to the tilted state, and finally press against the bristles of the roller brush. At this time, part of the brush handle is clamped between the actuator and the outer wall of the positioning table.

[0014] Preferably, the positioning platform has a long strip structure with an L-shaped cross-section, and the positioning opening is located at the bottom of the positioning platform;

[0015] When the brush is clamped, a portion of the brush handle is held between the actuating end and the top outer wall of the positioning platform.

[0016] Preferably, there are multiple positioning ports, which are arranged at intervals along the length of the positioning platform.

[0017] Preferably, the clamp includes a telescopic cylinder and a clamping plate connected to the output end of the telescopic cylinder, the clamping plate constituting the actuating end;

[0018] When there are multiple brushes, the clamp can act on the handles of all brushes simultaneously to achieve synchronous clamping.

[0019] Preferably, a heating element is provided in the working chamber for heating the cleaning fluid.

[0020] Preferably, the frame is also equipped with a circulation and purification system for discharging the dirty cleaning fluid in the working chamber and replenishing it with clean cleaning fluid.

[0021] Preferably, the working chamber is provided with a cleaning fluid inlet and a cleaning fluid outlet on its cavity wall;

[0022] The circulating purification system is used to perform a replacement operation of the cleaning fluid. The replacement operation includes discharging the turbid cleaning fluid in the working chamber through the cleaning fluid outlet, and then delivering clean cleaning fluid to the working chamber through the cleaning fluid inlet.

[0023] The circulating purification system can be implemented in two independent configurations:

[0024] In the first configuration, an external cleaning fluid supply source is directly connected to the cleaning fluid inlet via a pipeline;

[0025] In the second configuration, a liquid storage chamber is added inside the frame, and an external cleaning fluid supply source is connected to the liquid storage chamber to replenish it with clean cleaning fluid. The liquid storage chamber is connected to the cleaning fluid inlet through an independent liquid supply pipeline.

[0026] Preferably, in the second configuration, a delivery pump is provided on the liquid supply pipeline.

[0027] Preferably, a baffle is provided on the inner wall of the working chamber. The baffle is located in front of the cleaning fluid inlet and is used to receive the cleaning fluid flowing in from the cleaning fluid inlet and guide it to flow smoothly to the bottom of the working chamber to prevent the cleaning fluid from splashing.

[0028] Preferably, the frame is further provided with a recycling chamber, and the recycling chamber is connected to the working chamber through at least one through hole;

[0029] The working cavity is provided with a surrounding edge that surrounds the through hole;

[0030] When the level of the cleaning fluid in the working chamber exceeds the height of the surrounding edge, the excess cleaning fluid will overflow the surrounding edge and flow into the recovery chamber through the through hole.

[0031] The cleaning machine provided by this utility model has significant advantages over existing technologies. By incorporating a cleaning mechanism including a roller brush and a unique fixing mechanism consisting of a clamp and a positioning platform, this equipment achieves efficient and automated cleaning of brushes coated with cured adhesive. During cleaning, the brushes are reliably fixed and swing from an upright to an inclined position, allowing the brush heads to fully contact and rub against the continuously rolling roller brush bristles with stable and appropriate pressure. This greatly improves the thoroughness of cleaning stubborn adhesive residue between the bristles, resulting in a cleaning effect far superior to traditional manual brushing. Simultaneously, this design supports multi-station operation, processing multiple brushes simultaneously. Combined with an optional heating and circulation purification system, it further ensures continuous and efficient cleaning capabilities by heating to soften the adhesive and automatically replacing the cleaning fluid flow. This fundamentally solves the problems of time-consuming, labor-intensive, and uneven results associated with manual cleaning, and also avoids the enormous waste and cost pressure caused by frequently replacing brushes. In addition, the carefully designed anti-splash baffles and overflow recovery chamber in the equipment together ensure the smooth operation and clean working environment, ultimately achieving multiple positive effects such as improving production efficiency, reducing production costs, and promoting environmentally friendly and safe production.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0039] This utility model proposes a cleaning machine for cleaning adhesive application tools.

[0040] In this embodiment of the utility model, such as Figures 1 to 4 As shown, the cleaning machine for cleaning adhesive brushes includes a frame 1, a cleaning mechanism, and a fixing mechanism.

[0041] The frame 1 constitutes the main body of the equipment, and a working chamber 11 is provided inside it. The working chamber 11 is used to contain cleaning fluid, which can be water or a specific organic solvent.

[0042] The cleaning mechanism is located within the working chamber 11, and its core component is a roller brush 21. This roller brush 21 is partially or completely immersed in the cleaning solution. One end of the roller brush 21 is rotatably mounted on the side wall of the working chamber 11 via a bearing, and the other end is connected to the drive end of a drive mechanism 22 located outside the frame 1, such as the output shaft of a motor. A sealing structure, such as a mechanical seal or an oil seal, is provided at the through hole between the motor's output shaft and the side wall of the working chamber 11 to achieve dynamic sealing, ensuring smooth rotation of the roller brush 21 while effectively preventing leakage of the cleaning solution from the working chamber 11.

[0043] The fixing mechanism is also located within the working chamber 11 and is used to fix the brush during the cleaning process. This mechanism consists of a clamp arranged vertically and a positioning platform 3. The positioning platform 3 has at least one positioning opening 31, the shape and size of which are suitable for supporting the brush handle. During operation, the brush is placed with the brush head down and the brush handle up, so that a portion of the brush handle is placed in the positioning opening 31. At this time, the brush head naturally hangs below the positioning opening 31 and is opposite to, but not yet in contact with, the bristles of the roller brush 21 in front. The clamp has a movable actuator. When this actuator, for example, a clamping plate 42, moves in the clamping direction, it pushes the upper end of the brush handle, causing the entire brush to swing backward at an angle from its initial vertical position, changing to an inclined position, using the contact point with the positioning opening 31 as a fulcrum. This allows the brush head to be stably pressed against the surface of the roller brush 21 bristles. In this clamped state, a portion of the brush handle is reliably held between the actuator of the clamp and the outer wall of the positioning platform 3.

[0044] Specifically, this embodiment optimizes the positioning platform 3. The positioning platform 3 is designed as a long strip with an L-shaped cross-section. The positioning port 31 is located on the horizontal portion at the bottom of the L-shaped positioning platform 3. When the brush is clamped, a portion of the brush handle is firmly held between the actuating end and the outer wall of the top of the vertical portion of the L-shaped positioning platform 3. This L-shaped structure provides a stable support surface for clamping.

[0045] Specifically, to improve cleaning efficiency, this embodiment sets the number of positioning ports 31 to multiple. These positioning ports 31 are arranged at equal intervals along the length of the elongated positioning platform 3, so that multiple brushes can be fixed at the same time to achieve batch cleaning.

[0046] Specifically, this embodiment provides a detailed description of the clamp. The clamp includes a telescopic cylinder 41 serving as a power source and a clamping plate 42 connected to the end of the piston rod of the cylinder 41, which constitutes the actuating end. When multiple brushes need to be fixed, the clamping plate 42 has sufficient width to simultaneously contact and push the upper ends of the handles of all brushes, achieving one-button synchronous clamping and release, making the operation simple and efficient.

[0047] Specifically, in this embodiment, a heating element 5, such as an electric heating tube, is added inside the working chamber 11. This heating element 5 can heat the cleaning fluid inside the working chamber 11. The heated cleaning fluid can more effectively soften the cured adhesive on the brush, thereby significantly improving the cleaning effect and speed.

[0048] Specifically, in this embodiment, a circulating purification system is added to the frame 1. This system is used to drain the cleaning fluid from the working chamber 11 and replenish it with new clean cleaning fluid after the cleaning fluid becomes turbid, so as to maintain the cleaning effect.

[0049] Specifically, this embodiment further illustrates two specific configurations of the circulating purification system. The working chamber 11 is provided with a cleaning fluid inlet 100 and a cleaning fluid outlet 200 on its chamber wall.

[0050] The core function of the circulating purification system is to perform a replacement operation, that is, firstly, the dirty cleaning liquid in the working chamber 11 is completely discharged through the cleaning liquid outlet 200, and then the clean cleaning liquid is transported into the working chamber 11 through the cleaning liquid inlet 100.

[0051] This system has two independent implementation configurations:

[0052] First configuration: An external cleaning fluid supply source, such as a central liquid supply system in the plant area, is directly connected to the cleaning fluid inlet 100 of the working chamber 11 via a pipeline.

[0053] Second configuration: An additional liquid storage chamber 12 is added inside the frame 1. The external cleaning fluid supply source is first connected to this liquid storage chamber 12 to replenish the cleaning fluid. The liquid storage chamber 12 is then connected to the cleaning fluid inlet 100 of the working chamber 11 through an independent supply pipeline.

[0054] Specifically, in this embodiment, a delivery pump 300, such as a small centrifugal pump, is installed on the liquid supply pipeline connecting the liquid storage chamber 12 and the working chamber 11. This pump provides power to ensure that the clean cleaning fluid in the liquid storage chamber 12 can be pumped into the working chamber 11 stably and quickly.

[0055] Specifically, in this embodiment, a baffle 13 is provided on the inner wall of the working chamber 11. The baffle 13 is located in front of the cleaning fluid inlet 100. When the clean cleaning fluid flows in at high speed, it will first hit the baffle 13, thereby being buffered and guided, so that it flows smoothly along the baffle 13 to the bottom of the working chamber 11, effectively preventing splashing caused by the liquid directly impacting the liquid surface or the chamber wall.

[0056] Specifically, in this embodiment, a recovery chamber 14 is added to the frame 1. The recovery chamber 14 is connected to the working chamber 11 via at least one through hole. Inside the working chamber 11, a surrounding edge 15 is provided, which surrounds the through hole internally, or the surrounding edge 15, in conjunction with a portion of the inner wall of the working chamber 11, surrounds the through hole internally, thereby forming an overflow weir. When cleaning fluid is added to the working chamber 11, if the liquid level exceeds the top of the surrounding edge 15, the excess liquid will overflow from the top of the surrounding edge 15 into its interior, and then smoothly flow into the recovery chamber 14 through the through hole below. This structure achieves automatic control of the liquid level in the working chamber 11 and can recover overflow liquid, maintaining a clean environment.

[0057] Specifically, to facilitate rapid surface rinsing of the cleaned brushes, this embodiment includes a cup holder 16 located at an easily accessible position on the outside of the frame 1, for holding a cup filled with clean water. After the brushes are removed from the working chamber 11, their brush heads can be immediately immersed in the clean water in the cup for a simple rinse to remove any remaining solvent or adhesive particles that may adhere to the surface. This design, as a supplement to the main cleaning process, provides significant operational convenience, eliminating the need for operators to prepare additional containers or move to other workstations to complete the final rinsing step, effectively improving the overall continuity and efficiency of the operation.

[0058] Specifically, to further optimize the overall structural layout, improve the operational stability of the gripper, and simplify the assembly process, this embodiment features an enhanced design for the positioning platform 3. The top of the positioning platform 3 is integrally extended with a support portion 32. This support portion 32 has a dual function: firstly, it provides a stable mounting base for the gripper, allowing it to be directly fixed to the support portion 32, thus maintaining a fixed relative position between the gripper's actuator and the positioning platform 3, resulting in more precise and reliable operation; secondly, the positioning platform 3 and its extended support portion 32, as a single component, can be fixedly installed to the preset assembly position of the working cavity 11 via bolts or snap-fit ​​connections, achieving a reliable connection between the positioning platform 3 and the frame 1, simplifying the internal structure assembly process, and enhancing the overall integrity and rigidity of the fixing mechanism.

[0059] The cleaning machine provided by this utility model has significant advantages over existing technologies. By incorporating a cleaning mechanism including a roller brush and a unique fixing mechanism consisting of a clamp and a positioning platform, this equipment achieves efficient and automated cleaning of brushes coated with cured adhesive. During cleaning, the brushes are reliably fixed and swing from an upright to an inclined position, allowing the brush heads to fully contact and rub against the continuously rolling roller brush bristles with stable and appropriate pressure. This greatly improves the thoroughness of cleaning stubborn adhesive residue between the bristles, resulting in a cleaning effect far superior to traditional manual brushing. Simultaneously, this design supports multi-station operation, processing multiple brushes simultaneously. Combined with an optional heating and circulation purification system, it further ensures continuous and efficient cleaning capabilities by heating to soften the adhesive and automatically replacing the cleaning fluid flow. This fundamentally solves the problems of time-consuming, labor-intensive, and uneven results associated with manual cleaning, and also avoids the enormous waste and cost pressure caused by frequently replacing brushes. In addition, the carefully designed anti-splash baffles and overflow recovery chamber in the equipment together ensure the smooth operation and clean working environment, ultimately achieving multiple positive effects such as improving production efficiency, reducing production costs, and promoting environmentally friendly and safe production.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
