[0002] Down dehydration refers to the process of removing excess moisture from down or down-containing products (such as down jackets). It requires gentle handling to avoid damaging the down structure and loft, which would affect its warmth retention. In the down processing stage, the washed down is spun dry in a dehydrator.

Commonly used equipment includes washing machines with a gentle or down jacket mode that can achieve low-speed dehydration, and dedicated dehydrators used in the dehydration process of down processing.

[0003] For example, utility model patent CN212902276U discloses an energy-saving dehydration device for down products, including an outer box. A moving mechanism is fixedly connected to the bottom of the outer box. The moving mechanism includes a support column, a fixed frame is fixedly connected to one end of the support column, rollers are movably connected to the bottom of the fixed frame, and a clamping plate is movably connected to the top of the fixed frame.

The side of the buffer support plate away from the movable buffer rod is close to the outer surface of the dehydration cylinder. A circular convex ring is fixedly installed on the outer surface of the end of the movable buffer rod located inside the limiting shell. A spring is provided on one side of the circular convex ring. By connecting the shell, it is easy to form a whole with the outer protective shell. This facilitates the dehydration operation of the down to be dehydrated in the dehydration cylinder, and the dehydrated water can enter the conical partition inside the connecting shell to collect for subsequent discharge.

[0008] Preferably, the limiting mechanism includes protrusions and rubber limiting rollers. Multiple protrusions are fixedly installed on the inner side wall of the limiting protrusion ring, and rubber limiting rollers are rotatably connected inside the multiple protrusions. The outer surface of the rubber limiting rollers contacts the side of the dewatering cylinder near the top. The rubber limiting rollers facilitate limiting the dewatering cylinder near the top, thereby improving its stability during rotation.

[0009] Preferably, the drive assembly includes a bearing housing, a main drive spline shaft, a first pulley, a motor, and a second pulley. The bearing housing is fixedly installed on the inner bottom surface of the connecting housing. The main drive spline shaft is fixedly installed in the middle of the bearing housing.

[0011] Preferably, a drainage pipe is fixedly installed on one side of the connecting shell to facilitate the drainage of moisture after the down has been dehydrated.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0016] 1. In this application, a top flexible limiting system can be formed by setting a limiting protruding ring and a rubber limiting roller. The rubber limiting roller restricts the radial sway of the dewatering cylinder through rolling contact, avoiding the wear problem caused by the rigid contact of traditional pulleys. The spring, movable buffer rod, and buffer support plate structure inside the limiting housing constitute the middle and lower elastic buffer layers. When the dewatering cylinder vibrates radially due to centrifugal force, the spring absorbs the vibration energy through compression deformation, and the buffer support plate suppresses the amplitude through flexible contact, avoiding the problem of uncontrolled vibration at the bottom of the dewatering cylinder. During the dewatering process, centrifugal force drives water to be thrown to the inner wall of the outer protective housing and guided to the drainage pipe through the conical partition. The bottom shock-absorbing rubber seat and the support foot form a three-stage vibration reduction system. The vibration transmission is further attenuated through the viscoelastic deformation of the rubber material, preventing the device from shifting. This device not only ensures the high-speed rotation stability of the dewatering cylinder, but also significantly reduces component wear, achieving efficient dewatering operation with low vibration and low noise.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] refer to Figures 1-5 As shown, a down dehydration and shock absorption device includes an outer protective shell 1. A feeding port 2 is provided on the top surface of the outer protective shell 1. Multiple arc-shaped positioning grooves 17 are provided on the side of the feeding port 2 on the top surface of the outer protective shell 1. A sealing plate 18 is provided on the top surface of the outer protective shell 1. Multiple arc-shaped positioning protrusions 19 corresponding to the arc-shaped positioning grooves 17 are fixedly installed on the bottom surface of the sealing plate 18. The arc-shaped positioning protrusions 19 are inserted into the interior of the arc-shaped positioning grooves 17. A handle is fixedly installed on the top surface of the sealing plate 18. A dehydration cylinder 3 is provided inside the outer protective shell 1. The body 1 has two sections. The section near the top is fixed with bolts, which facilitates the maintenance of the internal structure of the outer protective shell 1. The outer protective shell 1 provides protection for the internal structure and prevents down or water from splashing out during the dehydration process, ensuring a clean working environment. The feeding port 2 facilitates the feeding of down. The sealing plate 18 achieves a quick and tight seal through the cooperation of the arc-shaped positioning protrusion 19 and the arc-shaped positioning groove 17, preventing air leakage during dehydration and affecting the dehydration efficiency. At the same time, the handle makes it easy for operators to open and close the sealing plate 18, improving the convenience of operation.

[0025] refer to Figures 1-5As shown, a connecting shell 4 is fixedly installed at the bottom of the outer protective shell 1 by bolts. A shock-absorbing rubber seat 14 is fixedly installed on the bottom surface of the connecting shell 4. A bottom support plate 15 is fixedly installed on the bottom surface of the shock-absorbing rubber seat 14. Multiple support feet 20 are fixedly installed near the corners of the bottom surface of the bottom support plate 15, and hard rubber pads are fixedly installed at the bottom ends of the multiple support feet 20. Through the cooperation of the shock-absorbing rubber seat 14 and the bottom support plate 15, the vibration generated during the operation of the device can be effectively absorbed, reducing the transmission of vibration to the ground and reducing the impact on the surrounding environment. The hard rubber pads at the bottom ends of the support feet 20 increase the friction with the ground, preventing the device from shifting during operation, and further buffering vibration to improve the stability of the device.

[0026] refer to Figures 1-5 As shown, a conical baffle 5 is fixedly installed inside the connecting housing 4, and a drain pipe 16 is fixedly installed through one side of the connecting housing 4. A drive assembly 6 connected to the dewatering cylinder 3 is installed inside the connecting housing 4. The conical baffle 5 guides the water thrown out during the dewatering process to flow to the drain pipe 16, preventing water accumulation from affecting the operation of the device. The drain pipe 16 can promptly discharge the water generated during dewatering, keeping the inside of the device dry. The drive assembly 6 provides power to the dewatering cylinder 3. All components work together to ensure a stable and efficient dewatering process.

[0027] refer to Figures 1-5 As shown, the drive assembly 6 includes a bearing housing 601, a main drive splined shaft 602, a first pulley 603, a motor 604, and a second pulley 605. The bearing housing 601 is fixedly installed on the inner bottom surface of the connecting housing 4, and the main drive splined shaft 602 is fixedly installed in the middle of the bearing housing 601. The top end of the main drive splined shaft 602 extends into the interior of the outer protective housing 1, and the top end of the main drive splined shaft 602 is connected to the bottom surface of the dehydration cylinder 3 via a spline. The bearing housing 601 provides stable support for the rotation of the motor 604, reducing friction and shaking during rotation. A spline groove is provided at the bottom of the dehydration cylinder 3, and the top end of the main drive splined shaft 602 is inserted into the spline groove. The main drive splined shaft 602 is connected to the dehydration cylinder 3 via a spline, which can transmit a large torque, ensuring the reliability and stability of power transmission, and enabling the dehydration cylinder 3 to rotate smoothly and at high speed.

[0028] refer to Figures 1-5As shown, a pulley 603 is fixedly mounted on the outer surface of the main drive spline shaft 602, and a motor 604 is fixedly mounted on the inner bottom surface of the connecting housing 4. A pulley 605 is fixedly mounted on the drive end of the motor 604. The pulley 605 and the pulley 603 are connected by a transmission belt. A control panel 21 is fixedly mounted on the right side of the outer protective housing 1, and the motor 604 is electrically connected to the control panel 21. The belt drive structure has a certain buffering and vibration absorption capacity, which can reduce the impact of the motor 604 during startup and operation on the dewatering cylinder 3. The control panel 21 allows the operator to control the start, stop, speed and other parameters of the motor 604, so as to achieve precise control of the dewatering process and improve the dewatering efficiency and quality.

[0029] refer to Figures 1-5 As shown, a limiting ring 7 is fixedly installed on the inner top surface of the outer protective shell 1. The top of the dehydration cylinder 3 is inserted into the inside of the limiting ring 7. The limiting ring 7 is equipped with a limiting mechanism 8 connected to the dehydration cylinder 3. The limiting mechanism 8 includes a protrusion 801 and a rubber limiting roller 802. Multiple protrusions 801 are fixedly installed on the inner side wall of the limiting ring 7, and the rubber limiting roller 802 is rotatably connected inside each of the multiple protrusions 801. The outer surface of the rubber limiting roller 802 contacts the side of the dehydration cylinder 3 near the top. The limiting ring 7 facilitates the limiting of the top of the dehydration cylinder 3, preventing the dehydration cylinder 3 from moving up and down during high-speed rotation. The rubber limiting roller 802 in the limiting mechanism 8 contacts the dehydration cylinder 3, which can limit the radial sway of the dehydration cylinder 3. At the same time, the rubber roller can play a buffering role, reducing the rigid collision between the dehydration cylinder 3 and the limiting ring 7, and reducing vibration and noise.

[0030] refer to Figures 1-5 As shown, a limiting shell 9 is fixedly installed on the inner wall of the outer protective shell 1. Multiple movable buffer rods 10 are movably inserted through the inner wall surface of the limiting shell 9, and a buffer support plate 11 is fixedly installed at one end of each movable buffer rod 10. The side of the buffer support plate 11 away from the movable buffer rod 10 is close to the outer surface of the dehydration cylinder 3. A circular convex ring 12 is fixedly installed on the outer surface of the end of the movable buffer rod 10 located inside the limiting shell 9. A spring 13 is provided on one side of the circular convex ring 12. The buffer structure formed by the limiting shell 9, movable buffer rods 10, buffer support plate 11 and spring 13 can buffer the vibration when the dehydration cylinder 3 generates radial vibration through the compression and extension of the spring 13, thereby reducing the vibration amplitude. The buffer support plate 11 maintains a certain distance from the outer surface of the dehydration cylinder 3, which can not only limit the dehydration cylinder 3, but also avoid direct rigid contact, further reducing vibration and noise, and effectively improving the buffering and vibration reduction performance of the device.

[0031] The implementation principle of the down dehydration buffer and vibration damping device embodiment of this application is as follows: The operator first opens the sealing plate 18 by the handle, and then puts the down to be dehydrated into the dehydration cylinder 3 from the feeding port 2. Then, the sealing plate 18 is closed so that it is sealed by the arc-shaped positioning protrusion 19 cooperating with the arc-shaped positioning groove 17. Then, after setting the parameters on the control panel 21, the motor 604 is started. The second pulley 605 of the drive end of the motor 604 rotates, and drives the first pulley 603 on the main drive spline shaft 602 to rotate through the transmission belt. The main drive spline shaft 602 then drives the dehydration cylinder 3 to rotate at high speed, and the down is dehydrated by using centrifugal force.

[0032] During the dehydration process, the limiting protrusion 7 and the limiting mechanism 8 can limit and buffer the dehydration cylinder 3. The rubber limiting roller 802 restricts its radial sway. The buffer structure inside the limiting housing 9 buffers the radial vibration of the dehydration cylinder 3 through the spring 13, the movable buffer rod 10 and the buffer support plate 11, reducing the vibration transmitted to the outer protective housing 1. The water generated during dehydration is thrown towards the inner wall of the outer protective housing 1 under the action of centrifugal force and falls into the interior of the connecting housing 4. It is guided by the conical partition 5 and discharged through the drainage pipe 16. The shock-absorbing rubber seat 14, the bottom support plate 15 and the support foot 20 work together to absorb the vibration generated by the operation of the device, prevent the device from shifting, and ensure stable, low-vibration and low-noise operation of the entire dehydration process.

[0033] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
