[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] A pillow core, as Figure 1 shown, it includes a first pillow core 2 and a second pillow core 4. Among them, the first pillow core 2 is a down fiber pillow core. As Figure 2 shown, the first pillow core 2 includes a first pillowcase 21, and the first pillowcase 21 is filled with down fiber 22; larger down is used for filling, and its fluffiness is better, which can provide better support for the head and will not deform after long-term use. Moreover, down has the advantages of light weight, breathability, and non-stuffy feeling, effectively improving the overall use comfort of this pillow core.

[0037] The second pillow core 4 is a buckwheat pillow core. Similarly, as Figure 2 shown, the second pillow core 4 includes a second pillowcase 41, and the second pillowcase 41 is filled with buckwheat granules 42; natural and non-toxic buckwheat husks are used as fillers to ensure that every part of the pillow core is filled with the aroma of buckwheat husks, greatly improving the use feeling of the pillow core; and, buckwheat husks have good breathability and the advantages of being warm in winter and cool in summer, with a faint matte feeling, which can make people fall asleep comfortably. In addition, silver ion antibacterial granules are also filled in the second pillowcase 41 to further improve the use safety of this pillow core.

[0038] For the pillow core disclosed by the present invention, as Figure 1As shown, the first pillow core 2 and the second pillow core 4 are connected by a zipper 3, and the first pillow core 2 and the second pillow core 4 are arranged in the up-and-down order, thus combining the advantages of a down pillow core and a buckwheat pillow core. The connection method of the zipper 4 facilitates the installation and disassembly of the two-layer pillow core. At the same time, people can selectively use the first pillow core 2 or the second pillow core 4 according to their usage needs, and only need to turn the selected pillow core upwards, which is very convenient to use. In addition, to further improve the connection reliability between the first pillow core 2 and the second pillow core 4, as Figure 2 shown, a sheet-shaped magnetic snap 7 is also provided between the first pillow core 2 and the second pillow core 4. The magnetic snap 7 is arranged at a position close to the center, and the upper and lower sheets are respectively fixed on the first pillowcase 21 of the first pillow core 2 and the second pillowcase 41 of the second pillow core 4.

[0039] For the pillow core, people will be in contact with it all the time when sleeping. However, when people sleep, they will inevitably secrete sweat stains, oil stains and other scalp secretions. Traditional pillow cores mostly use a single layer of pillowcase. When the scalp secretions penetrate the pillowcase, they will soak the pillow core, making the pillow core become wet. The wet pillow core will become a breeding ground for various microorganisms, which will cause many potential health hazards to people. Therefore, for the pillow core disclosed in the present invention, a first stain-resistant layer 1 is detachably laid on the outer side of the first pillow core 2, and a second stain-resistant layer 5 is detachably laid on the outer side of the second pillow core 4;

[0040] As Figure 3 shown, both the first stain-resistant layer 1 and the second stain-resistant layer 5 are composed of a pure cotton layer 11, a latex layer 12, an anti-pollution layer 14, an oil-resistant layer 15, and a wear-resistant layer 16. Among them, the pure cotton layer 11 is located on the outermost layer. The pure cotton has good hygroscopicity, is soft and comfortable, and is in direct contact with people, with a good sense of use. The latex layer 12 is sandwiched between the pure cotton layer 11 and the anti-pollution layer 14. The latex layer 12 is a thin layer of latex pad. On the one hand, it supports the stain-resistant layer and makes it have a certain elasticity. On the other hand, it uses the oak protein in the latex of the latex pad to inhibit the latent bacteria and allergens, further improving the use safety of this pillow core. The anti-pollution layer 14 is located inside the latex layer 12. The anti-pollution layer 14 is made of activated carbon fiber. By using the adsorption effect of the activated carbon fiber, it can effectively eliminate pollution and ensure the health of users. The oil-resistant layer 15 is coated on the anti-pollution layer 14. The oil-resistant layer is a special oil-resistant coating for fabrics, such as a PU coating, which has good oil-resistant and water-resistant properties, and can prevent scalp secretions such as sweat stains and oil stains from infecting the filling inside the pillowcase. The wear-resistant layer 16 is located on the innermost side. The wear-resistant layer 16 is fixedly bonded to the oil-resistant layer 15. The wear-resistant layer 16 contacts the pillow core on the innermost side. The wear-resistant layer can be made of polyester fabric, which has low cost and good wear resistance.

[0041] Moreover, the first stain-resistant layer 1 and the second stain-resistant layer 5 are respectively detachably laid on the first pillow core 2 and the second pillow core 4, and are fixed by Velcro, with good fixing effect and convenient disassembly. Specifically: As Figure 2As shown in the figure, the first dirt-resistant layer 1 is detachably connected to the first pillow core 2 through the first magic tape 6. The first magic tape 6 is composed of a first magic male tape and a first magic female tape that are matched and pasted. The first magic male tape is fixed on the first dirt-resistant layer 1, and the first magic female tape is fixed on the first pillowcase 21 of the first pillow core 2. The second dirt-resistant layer 5 is detachably connected to the second pillow core 4 through the second magic tape 8. The second magic tape 8 is composed of a second magic male tape and a second magic female tape that are matched and pasted. The second magic male tape is fixed on the second dirt-resistant layer 5, and the second magic female tape is fixed on the second pillowcase 41 of the second pillow core 4.

[0042] At the same time, to prevent the first dirt-resistant layer 1 and the second dirt-resistant layer 5 from sliding during use and affecting the use, as Figure 4 shown, anti-slip bumps 9 are fixedly arranged on both the first pillowcase 21 and the second pillowcase 41. The anti-slip bumps on the first pillowcase 21 are located between the first pillowcase 21 and the first dirt-resistant layer 1, and the anti-slip bumps on the second pillowcase 41 are located between the second pillowcase 41 and the second dirt-resistant layer 5.

[0043] The present invention also discloses a pillow core filling machine for the pillow core, which is used for filling the first pillow core 2 of the above-mentioned pillow core;

[0044] As Figure 5 shown, the pillow core filling machine includes a main chassis 35, a mounting frame 36, a cotton feeding pipe 39, a main air blower 40, and a cotton filling platform 49;

[0045] A cotton mixing box 31 is installed above the main chassis 35. The down fiber is first put into the cotton mixing box 31 for uniform mixing. The cotton mixing box 31 is connected to a feeding pipe 32. The feeding pipe 32 extends into the main chassis 35, and a control valve 33 is installed on the feeding pipe 32. A conveyor belt 34 is installed in the main chassis 35. The conveyor belt 34 is located below the feeding pipe 32, and the outlet of the feeding pipe 32 is aligned with the conveyor belt 34, so that the down fiber in the cotton mixing box 31 can fall onto the conveyor belt 34;

[0046] An opening is formed on one side of the main chassis 35. The mounting frame 36 is located at the opening on one side of the main chassis 35. The mounting frame 36 has a mounting groove, and a weighing scale 47 is installed in the mounting groove. Thus, the conveyor belt 34 and the weighing scale 47 are connected at the opening position. The weighing scale 47 is located below the conveyor belt 34. During the conveying process of the conveyor belt 34, the down fiber can fall onto the weighing scale 47, and the down fiber is quantitatively weighed by the weighing scale 47;

[0047] A pushing mechanism 48 is arranged above the weighing scale 47, as Figure 6As shown, the pusher mechanism 48 includes a pusher plate 483 and a cylinder 481. The pusher plate 483 is in contact with the weighing scale 47. The cylinder 481 is connected to the pusher plate 483 through a cylinder piston 482. The cylinder 481 drives the pusher plate 483 to move back and forth to push the down fiber on the weighing scale 47 into the cotton feeding pipe 39.

[0048] For the weighing scale 47, it is linked with the control valve 33, the conveyor belt 34 and the pusher mechanism 48 through the PLC control system. After each weighing operation of the weighing scale 47 is completed, the pusher mechanism 48 starts to work first to push away the down fiber on the weighing scale. Then, the conveyor belt 34 and the control valve 33 are activated. The control valve 33 opens to feed the conveyor belt 34, and closes after the feeding is completed; the conveyor belt 34 moves forward to feed the weighing scale 47; when feeding, the pusher mechanism 48 has been reset to its initial position (i.e., Figure 5 the position near the rightmost end of the mounting frame in the figure). To avoid the pusher mechanism in the initial position affecting the feeding of the conveyor belt 34, the initial position of the pusher mechanism 48 is also below the conveyor belt 34.

[0049] The down fiber quantitatively weighed by the weighing scale 47 is fed into the cotton feeding pipe 39. Due to the height difference and gap between the weighing scale 47 and the cotton feeding pipe 39, to enable the down fiber to effectively and smoothly enter the cotton feeding pipe 39, as Figure 5 shown, the mounting frame 36 is also fixedly connected with an obliquely arranged guide plate 46 at one end. One end of the guide plate 46 is flush with the weighing scale 47 and is kept seamlessly connected. The other end of the guide plate 46 extends into the cotton feeding pipe 39; at the same time, a limiting plate 45 is provided on the cotton feeding pipe 39. The limiting plate 45 is located at one end of the cotton feeding pipe 39 close to the weighing scale 47. Through the limiting plate 45, the down fiber can be prevented from splashing at the inlet position of the cotton feeding pipe 39 to a certain extent.

[0050] At the same time, to increase the flow rate of the down fiber in the cotton feeding pipe 39 and improve the filling efficiency of the pillow core; the cotton pipe 39 is also connected to an auxiliary air blower 37 through an auxiliary air duct 38. The auxiliary air blower 37 blows in a linearly flowing air to accelerate the forward speed of the down fiber.

[0051] The cotton feeding pipe 39 is connected to the main air blower 40. The main air blower 40 is provided with a cotton filling port 44. The cotton filling port 44 is the position where the pillowcase is sleeved. Under the guidance of the main air blower 40, the down fiber to be filled is rushed into the pillowcase from the cotton filling port 44.

[0052] A cotton filling platform 49 is also provided at the lower position of the cotton filling port 44. During the filling process of the pillow core, the pillow core contacts the cotton filling platform 49. The cotton filling platform 49 can vibrate quickly to realize the beating of the pillow core during the filling process of the pillow core, making the pillow core more flat. The cotton filling platform 49 is connected to a vibration motor 51 through a buffer spring 50, and the vibration motor 51 provides power.

[0053] The pillow core filling machine disclosed in the present invention has a specific pillow core filling method as follows:

[0054] Put down fibers for filling pillow core No. 1 in the mixing box 31 in advance, open the control valve 33, and feed the down fibers to the conveyor belt 34 through the feeding pipe 32. After the feeding is completed, the control valve 33 is closed;

[0055] The conveyor belt 34 delivers the down fibers to the weighing scale 47, and the pushing mechanism 48 is in the initial position. The weighing scale 47 quantitatively weighs the down fibers, and the weighed amount is determined according to the amount of down fibers required for the pillow core No. 1. After the weighing is completed by the weighing scale 47, the pushing mechanism 48 pushes the down fibers on the weighing scale 47, and under the action of the guide plate 46, the down fibers enter the cotton feeding tube 39. At the same time, the conveyor belt of the weighing scale 47 is closed, and the control valve 33 is opened to carry out the next round of weighing.

[0056] The down fibers entering the cotton feeding tube 39 further enter the main air blower 40, and under the action of the main air blower 40, the down fibers are filled into the No. 1 pillowcase set at the cotton filling port 44; during the filling process, the vibration motor 51 drives the cotton filling platform 49 to continuously vibrate and beat the No. 1 pillow core during the filling process, thereby improving the cotton filling effect of the No. 1 pillow core.

[0057] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also belong to the protection scope of the present invention.
