Description

Technical Field

[0001] This utility model belongs to the field of sealing technology, specifically relating to a drying device for surface treatment of sealing rings. Background Technology

[0002] Currently, most sealing rings on the market are made of rubber. Rubber is a polymer material with unique elasticity and flexibility. Its molecular chain structure gives rubber excellent resilience, which can quickly return to its original shape after stretching or compression. At the same time, rubber is also extremely flexible.

[0003] For washing machine sealing rings, due to their large size and softness, the key issues during surface finishing or treatment are how to clamp and heat-dry them.

[0004] However, when using conventional methods (such as using grippers) for clamping and positioning, the sealing ring is easily unable to maintain its natural unfolded state due to the difficulty in controlling the clamping force, making it difficult to meet the positioning requirements. Furthermore, the sealing ring is prone to deformation, which can create dead corners on the inner wall, making it impossible to ensure complete drying. In addition, during the drying process, the sealing ring can only be kept fixed and dried by rotating the drying gun (if the sealing ring rotates, the clamping position is easily squeezed and damaged under centrifugal force). This is not only cumbersome to operate, but also poses safety hazards due to the large range of motion of the drying gun and the high difficulty of the process. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved drying device for surface treatment of sealing rings.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A drying apparatus for surface treatment of sealing rings, comprising:

[0008] The positioning unit includes a turntable, a support ring disposed above the turntable, a connecting frame connecting the turntable and the support ring, and a power unit that drives the turntable to rotate around a vertical center line. The sealing ring is inserted into the inner ring of the support ring and suspended on the support ring in a naturally unfolded state. The connecting frame forms a positioning area in the circumferential direction that matches the sealing ring.

[0009] The drying unit includes a drying component that extends into the inner ring of the sealing ring from top to bottom and blows a drying airflow. As the rotating disc drives the sealing ring to rotate, the drying area formed by the drying component covers the inner wall of the sealing ring, and the drying airflow simultaneously generates a force that drives the sealing ring to maintain a downward unfolding trend.

[0010] Preferably, the connecting frame forms a positioning area in the circumferential direction that matches the sealing ring. The sealing ring is suspended from the top on the support ring, and the lower part of the sealing ring is positioned within the positioning area. Here, as the turntable rotates, the positioning area formed by the connecting frame effectively prevents the sealing ring from swinging under centrifugal force, enhancing the support for the sealing ring.

[0011] According to a specific embodiment and preferred aspect of this utility model, the sealing ring includes an inverted portion hanging on a support ring, a fitting portion that conforms to the inner ring of the support ring from its outer periphery, and a suspended portion suspended between the support ring and the turntable. Based on the contact between the inverted portion and the fitting portion, the sealing ring is stably hooked onto the support ring from its opening end, which not only facilitates the full unfolding of other parts of the sealing ring but also increases the stability of the inverted hanging. Simultaneously, the sealing ring can better conform to the inner ring of the support ring, preventing it from falling off due to an excessively large support ring or being squeezed and twisted due to an excessively small support ring.

[0012] Preferably, the connecting frame includes multiple support rods spaced annularly around the rotation center line of the turntable, with the suspended portion abutting against the multiple support rods from the outer wall. In some specific embodiments, there are three support rods arranged in an equilateral triangle. That is, based on the stable support formed by the equilateral triangle, the support ring maintains stable top support, while reducing the number of support rods, optimizing the structure, and increasing the exposed area for ease of operation.

[0013] According to another specific embodiment and preferred aspect of this utility model, each support rod includes a screw and a nut, wherein the lower end of the screw extends downward through the turntable, and the upper end is fixedly connected to the support ring. The nut cooperates with the screw to adjust the distance between the support ring and the turntable. Here, the support height of the support ring is adjusted by the relative cooperation of the nut and the screw to meet the positioning requirements of sealing rings of different specifications, thereby increasing the practicality of positioning and matching.

[0014] According to another specific embodiment and preferred aspect of this utility model, the center lines of the turntable, the support ring, and the sealing ring are aligned. This facilitates quick and accurate positioning of the sealing ring.

[0015] According to another specific embodiment and preferred aspect of this utility model, the turntable is provided with through holes penetrating itself; there are multiple sets of through holes, each set being arranged in a circular array with the rotation center line of the turntable as the reference, and the inner diameter of each set of through holes is equal. This reduces the weight of the turntable, reduces material usage, saves costs, and makes rotation easier; the turntable's mass distribution is uniform, improving the overall rotational stability of the turntable and preventing center of gravity shift.

[0016] According to another specific embodiment and preferred aspect of the present invention, the drying unit further includes a truss, an adjustment seat movably connected to the truss and capable of horizontal adjustment along the horizontal direction, and the drying component is movably connected to the adjustment seat vertically.

[0017] Preferably, the adjusting seat has vertically inclined guide rails, and the drying component is slidably connected to the guide rails, wherein the direction of the drying airflow blown by the drying component is parallel to the extension direction of the guide rails. This facilitates precise control of the blowing distance of the drying airflow relative to the inner wall of the sealing ring, so as to flexibly match the surface treatment needs of sealing rings of different sizes.

[0018] Furthermore, the angle between the direction of the drying airflow blown by the drying component and the vertical direction is 30° to 60°. Here, based on the layout of the drying airflow direction, the drying airflow is obliquely blown to the inner wall of the sealing ring and then reversed to flow downward along the inner wall of the sealing ring, thereby driving the sealing ring to maintain a downward unfolding tendency.

[0019] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] Existing technologies using conventional clamping and positioning methods often suffer from difficulty in controlling the clamping force, leading to the sealing ring failing to maintain its naturally unfolded state and thus failing to meet positioning requirements. Furthermore, the sealing ring is prone to deformation, resulting in dead corners on the inner wall and hindering complete drying. Additionally, during the drying process, the sealing ring must be kept fixed while the drying gun rotates for drying (if the sealing ring rotates, centrifugal force can easily cause compression at the clamping position, resulting in damage). This is not only cumbersome but also presents safety hazards due to the large range of motion and difficulty of the drying gun's rotation. This application addresses the issue of the sealing ring's surface... The drying device for surface treatment features an integrated structural design that cleverly addresses the shortcomings and defects of existing technologies. With this device, a sealing ring is inserted into the inner ring of a support ring and suspended from it, maintaining the sealing ring in a naturally unfolded state. Then, a power unit drives a turntable to rotate, causing the sealing ring to rotate as well. A drying component extends from top to bottom into the inner ring of the sealing ring and blows drying air towards its inner wall, creating a drying area that covers the inner wall of the sealing ring. Therefore, compared to existing technologies, this invention, on the one hand, uses the turntable, support ring, and connecting frame to suspend the sealing ring, allowing it to fully unfold in its natural state, meeting positioning requirements; on the other hand, based on the suspended and naturally unfolded sealing ring, the turntable's rotation and the drying component's cooperation achieve a zero-gripping and zero-damage rotation of the sealing ring. The drying area formed by the drying component fully covers the inner wall of the sealing ring, making operation simple, convenient, and with a high safety factor. Attached Figure Description

[0033] See Figures 1 to 3 As shown, the drying device for surface treatment of the sealing ring in this embodiment includes a positioning unit 1 and a drying unit 2.

[0034] Specifically, the positioning unit 1 includes a turntable 10, a support ring 11 disposed above the turntable 10, a connecting frame 12 connecting the turntable 10 and the support ring 11, and a power unit 13 that drives the turntable 10 to rotate around a vertical center line. The sealing ring Q is inserted into the inner ring of the support ring 11 and is suspended on the support ring 11 in a naturally unfolded state. The connecting frame 12 forms a positioning area in the circumferential direction that matches the sealing ring Q.

[0035] The turntable 10 has multiple through holes k that penetrate itself. The multiple through holes k are divided into multiple groups and are staggered relative to each other. Each group is arranged in a ring array with the center of the turntable 10 as the reference. Moreover, the inner diameter of each group of through holes k is equal, and there is a difference in the inner diameter of two adjacent groups of through holes k.

[0036] In this embodiment, the turntable 10 has two sets of through holes k, each set consisting of three identical circular through holes k. The inner diameter of the through hole k closer to the axis is larger than the inner diameter of the through hole k farther from the axis. This ensures a uniform mass distribution on the turntable, improves the overall rotational stability of the turntable, and prevents the center of gravity from shifting.

[0037] The support ring 11 is annular, and when the sealing ring Q is positioned, the center lines of the turntable 10, the support ring 11, and the sealing ring Q coincide. The sealing ring Q includes an inverted portion Q1 hanging on the support ring 11, a fitting portion Q2 that adheres to the inner ring of the support ring 11 from the outer periphery, and a suspended portion Q3 suspended between the support ring 11 and the turntable 10. Based on the contact between the inverted portion and the fitting portion, the sealing ring is stably hooked onto the support ring from the end of the ring opening, which not only facilitates the full unfolding of other parts of the sealing ring but also increases the stability of the inverted hanging; at the same time, the sealing ring can better fit the inner ring of the support ring, and will not fall off due to an excessively large support ring or be squeezed and twisted due to an excessively small support ring.

[0038] The connecting frame 12 includes multiple support rods 120 arranged in a ring around the rotation center line of the turntable 10, with the suspended portion Q3 abutting against the multiple support rods 120 from the outer wall. In some specific embodiments, there are three support rods 120 arranged in an equilateral triangle. That is, based on the stable support formed by the equilateral triangle, the support ring is kept in place and provides stable support, while reducing the number of support rods, optimizing the structure, and increasing the exposed area for ease of operation.

[0039] The power unit 13 uses a conventional drive motor, and the output shaft of the drive motor is connected to the bottom center of the turntable 10.

[0040] For ease of implementation, each support rod 120 includes a screw a0 and a nut a1. The lower end of the screw a0 extends downward through the turntable 10, and the upper end is fixedly connected to the support ring 11. The screw a0 and nut a1 work together to adjust the distance between the support ring 11 and the turntable 10. Here, the support ring's top support height is adjusted by the relative cooperation of the nut and screw to meet the positioning requirements of sealing rings of different specifications, increasing the practicality of positioning and matching.

[0041] In this example, the drying unit 2 includes a truss 20 located above the positioning unit 1, an adjustment seat 21 movably connected to the truss 20, and a drying component 22 movably connected to the adjustment seat 21 and extending into the inner ring of the sealing ring Q from top to bottom to blow drying airflow. As the turntable 10 drives the sealing ring Q to rotate, the drying area formed by the drying component 22 covers the inner wall of the sealing ring Q, and the drying airflow simultaneously forms a force that drives the sealing ring Q to maintain a downward unfolding trend.

[0042] In some specific embodiments, the truss 20 has multiple connecting holes distributed laterally, and the adjusting seat 21 is correspondingly connected to each connecting hole for horizontal adjustment. The adjusting seat 21 has vertically inclined guide rails 210, and the drying component 22 is slidably connected to the guide rails 210, wherein the direction of the drying airflow blown by the drying component 22 is parallel to the extension direction of the guide rails 210. This facilitates precise control of the blowing distance of the drying airflow relative to the inner wall of the sealing ring, flexibly matching the surface treatment needs of sealing rings of different sizes.

[0043] Furthermore, the drying airflow blown by the drying component 22 forms an angle of 30° to 60° with the vertical direction. Therefore, the drying airflow is obliquely blown onto the inner wall of the sealing ring and then reversed to flow downwards along the inner wall of the sealing ring, thereby driving the sealing ring to maintain a downward unfolding tendency. In this embodiment, the angle is preferably 45°; the drying component 22 is a commercially available product and will not be described in detail here.

[0044] In summary, after adopting this drying device, the sealing ring is inserted into the inner ring of the support ring and suspended on the support ring, so that the sealing ring is kept in a naturally unfolded state; then the power unit drives the turntable to rotate, thereby rotating the sealing ring. The drying component extends into the inner ring of the sealing ring from top to bottom and blows drying airflow toward the inner wall of the sealing ring, and the resulting drying area covers the inner wall of the sealing ring. Therefore, compared with the prior art, this utility model has several advantages. First, the turntable, support ring, and connecting frame work together to suspend the sealing ring, allowing it to fully unfold in its natural state and meet positioning requirements. Second, based on the suspension and natural unfolding of the sealing ring, the turntable's rotation and the drying component work together to achieve zero-gripping and zero-damage rotation of the sealing ring. The drying area formed by the drying component can fully cover the inner wall of the sealing ring, making operation simple, convenient, and safe. Third, the distribution of through holes on the turntable ensures uniform mass distribution, improving the overall rotational stability of the turntable and preventing center of gravity shift. Fourth, the contact between the hanging part and the fitting part allows the sealing ring to be stably hooked onto the support ring from the end of the ring opening, facilitating the full unfolding of other parts of the sealing ring and increasing the stability of the hanging. Simultaneously, the sealing ring can better fit the inner ring of the support ring, preventing it from falling off due to an oversized support ring or being squeezed and twisted due to an undersized support ring. Fifth, the relative cooperation of the nut and screw adjusts the support ring's top support height to meet the positioning needs of sealing rings of different specifications, increasing the practicality of positioning and matching.

[0045] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
