Description

A device for loosening the elastic properties of hardened cotton

technical field

The invention relates to a tool for fluffing pillow cores, in particular to an elastic loosening device for hardened cotton.

Background technique

For bedding, pillows and other daily necessities filled with floc such as cotton, the floc will harden after a period of use, losing the excellent characteristics of looseness and reducing the comfort during use, especially the pillow pressure part of the pillow. Under the action of head pillow pressure and sweat water vapor, it is easy to harden and collapse quickly. If the hardened and collapsed pillow is thrown away, it will undoubtedly cause huge waste, and it is uncomfortable to use. The only way to restore the elasticity of the pillow is to put the pillow core The cotton inside is taken out and taken to the place where the cotton is plucked, and it is loosely plucked, but the amount of cotton in the cotton core of the pillow is small, which is not suitable for machine plucking; and the place to pluck cotton is not everywhere, even if you find the cotton Where there is cotton, cotton plucking will cause air pollution and cause respiratory diseases. The pillows will harden faster and be frequently sent to be plucked, which will increase the cost. These problems still need to be further solved.

Detailed ways

Embodiment 1 of the present invention, as shown in Figure 1, the hardened cotton elastic loosening device is provided with a core rod 1, a collar 2, and an elastic strip, the inner end of the core rod has a smooth tip 3, and the outer end of the core rod is provided with a handle 4 , the handle is connected with a rocker arm 7, and the collar is set on the outside of the core rod. The elastic strips are more than two arc-shaped elastic wires 5, which can be elastic metal wires or plastic strips. In this embodiment, there are eight, around the core rod. Circumferentially distributed, the elastic strips in this embodiment are stretched elastic strips, which are arc-shaped in their natural state, and can be stretched and tend to be straight. One end of the elastic strip is connected to the inner end of the core rod, and the other end of the elastic strip is connected to the collar. The core rod between the inner end of the rod and the collar is connected with a position-limiting projection 6 that blocks the collar. When using this embodiment, there is no need to disassemble the pillow or take out the cotton, just open a small opening, gather the elastic strip and insert the elastic strip part of the device into the pillow, then make the elastic strip bulge, and rotate the rocker arm to make the elastic The elastic bar rotates or slides the slip ring to vibrate and deform the elastic bar in the axial direction, and loosen the cotton near it to solve the hardening phenomenon. The workload of seam removal is small, and there is no need to find a place to pop the cotton. The low cost extends the service life of the pillow, and the economic cost is low. , strong environmental protection, and can adjust the deformation range of the elastic yarn to adapt to the size of the pillow.

Embodiment 2 of the present invention is shown in Fig. 2. The difference between the hardened cotton elastic loosening device and Embodiment 1 is that the elastic bar is a tension spring 12, which is sleeved on the core rod, and the two ends are respectively connected to the front end of the core rod and the slip ring. On the top, the rocker arm is connected to the slip ring. When using it, stretch the stretch spring to make it thinner, and then insert the elastic strip of the device into the pillow, relax the stretch spring to make the stretch spring thicker, and you can also rotate the rocker The arm rotates the elastic bar or slides the slip ring to vibrate and deform the elastic bar axially to loosen the cotton near it.

Embodiment 3 of the present invention is shown in Figure 3. The difference between the hardened cotton elastic loosening device and Embodiment 1 is that the elastic strips are compressed elastic strips, and the elastic strips are more than two arc-shaped elastic threads. In this embodiment, there are eight. The core rod is distributed around the circumference, and the natural state tends to be straight, which can be compressed into an arc shape. There is a compression elastic body 11 set on the core rod between the handle and the collar, which can be a spring or a bow, so that the compressed elastic bar is deformed. Bending, between the handle and the compressed elastic body, there is a hand-held sleeve 8 set outside the core rod against the sleeve. A cam 9 is provided on the annular edge of the hand-held sleeve near the collar side, and a cam 9 is provided on the collar. Axially driven protrusion 10 and handle 14 are provided on the hand-held sleeve 8. When using this embodiment, there is no need to disassemble the pillow or take out the cotton. Just open a small opening and use the hand-held sleeve to compress the elastic force body to make the elastic bar tend to be straight, then release the hand-held sleeve to bend the elastic bar, insert the elastic bar part of the device into the pillow, release the hand-held sleeve to make the elastic bar bulge, hold the hand-held sleeve, and rotate the rocker arm to The elastic strip rotates. During the rotation, the slip ring vibrates along the axial direction of the cam, causing the elastic strip to vibrate and deform in the axial direction. The effect of loosening the cotton near it is better, and the hardening phenomenon is solved. The workload of seam removal is small, and there is no need to find a place to spring cotton , The low cost extends the service life of the pillow, the economic cost is low, and the environmental protection is strong.

Embodiment 4 of the present invention is shown in Fig. 4. The difference between the hardened cotton elastic loosening device and Embodiment 3 is that the elastic bar is a compression spring 13, which is sleeved on the core rod, and the two ends are respectively connected to the front end of the core rod and the slip ring. , the rocker arm is connected to the slip ring, use the hand-held sleeve to compress the elastic body to make the compression spring stretch and become thinner, then insert the elastic strip part of the device into the pillow, loosen the hand-held sleeve to make the compression spring thicker, hold Hold the hand-held sleeve and rotate the rocker arm to rotate the tension and compression spring. During the rotation, the slip ring vibrates along the axial direction of the cam to deform the compression spring in the axial direction. The effect of loosening the cotton near it is better, and the compression elastic force increased at the bottom The elastic force exerted by the body 11 will make the compression spring deform, so that the user can save more effort, solve the hardening phenomenon, the workload of seam removal is small, there is no need to find a place to pop cotton, the low cost extends the service life of the pillow, the economic cost is low, and environmental protection Strong.

Embodiment 5 of the present invention is shown in Figure 5. On the basis of Embodiment 3, the elastic loosening device for hardened cotton is distributed with arc-shaped elastic wires outside the compression spring along the axial and circumferential directions. The ends are connected to different coils of the spring and positioned on the compression spring in the circumferential direction. The number of elastic wires is more distributed and the vibration area is larger. Moreover, the elastic wires and the compression spring vibrate and rotate synchronously to better realize multi-dimensional vibration and looseness. The function is more powerful, and the deformation range of the elastic wire can be adjusted to suit the size of the pillow core.

During implementation, the core rod can also adopt a multi-section telescopic structure to increase the stretching range and have a larger loose area.

In summary, the above is only a specific embodiment of the present invention, but it is not limited to the embodiment, and various technical features can also be recombined to achieve more implementations. All that are done according to this application without departing from the concept of the present invention, etc. Effect modification and prior art addition are all considered as the technical scope of the present invention.
