Description

Technical Field

[0001] This invention relates to the field of down pillow manufacturing technology, and in particular to an automatic down pillow winding device. Background Technology

[0002] A down pillow is a pillow with down as its filling. Down is primarily composed of animal feathers, such as duck feathers. Down is sandwiched between the fabric and the lining; it's a mixture of feathers and down. Feathers are the individual down feathers that provide support and allow the down to quickly spring back. Down, on the other hand, is the down cluster, the core of the down and its value. A down cluster is a three-dimensional spherical structure, composed of a core and numerous radiating down filaments, similar to a dandelion. Down filaments are made up of thousands of tiny, hollow scales. Each down filament has many segments filled with still air, which are injected into the layers during the manufacturing process.

[0003] Because of the large gaps within the down raw material, it is extremely easy for a large amount of dust to mix in during the production process. Especially during the winding process, as the down raw material is wound onto the winding roller, the layers of down raw material are squeezed together, causing the dust inside the down raw material to adhere more tightly, making it more difficult to remove in subsequent processing. Therefore, this application proposes an automatic down pillow winding device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic down pillow winding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic down pillow winding device includes a winding box, a winding roller rotatably connected to the inner wall of the winding box, a limit plate fixedly connected to the inner wall of the winding box, a conductive spring fixedly connected to the upper end of the limit plate, a lever fixedly connected to the upper end of the conductive spring, a dust-collecting housing fixedly connected to the inner wall of the winding box, an adsorption mechanism for adsorbing dust installed inside the dust-collecting housing, a knurled groove formed on the side wall of the winding roller, a fixed roller fixedly connected to the inner wall of the winding box and extending into the knurled groove, a lifting groove formed on the side wall of the fixed roller, a lifting rod slidably connected to the lifting groove, a magnetic plate fixedly connected to the side wall of the lifting rod, a roller rotatably connected to the side wall of the lifting rod and rolling on the inner wall of the knurled groove, a spiral coil installed in the lifting groove, and the spiral coil electrically connected to the conductive spring.

[0007] Preferably, the adsorption mechanism includes a rotating wheel rotatably connected to the inner wall of the take-up box, an electrode plate installed on the inner wall of the dust collection housing, a plurality of metal adsorption plates fixedly connected to the side wall of the rotating wheel, and the spiral coil supplying power to the electrode plate through a power supply circuit.

[0008] Preferably, a dust collection box is fixedly connected to the lower end of the dust collection housing, and the dust collection box is connected to a purification box through a conveying pipe. A filter screen is fixedly installed inside the purification box, and a negative pressure mechanism is connected to the purification box. The negative pressure mechanism is used to draw air into the purification box. A metal scraper is fixedly connected to the inner wall of the dust collection housing, and the metal scraper is grounded through a wire.

[0009] Preferably, the negative pressure mechanism includes a negative pressure plate, an air intake pipe, and an exhaust pipe. A negative pressure groove is formed on the side wall of the fixed roller. The negative pressure plate is slidably connected in the negative pressure groove. Both the air intake pipe and the exhaust pipe are connected to the negative pressure groove. An air intake one-way valve is installed in the air intake pipe. An exhaust one-way valve is installed in the exhaust pipe. The negative pressure plate is fixedly connected to the lifting rod through a connecting rod. The end of the air intake pipe away from the negative pressure groove is connected to the purification box.

[0010] Preferably, two return springs are fixedly connected to the upper end of the fixed roller, and two push plates are fixedly connected to the side wall of the lifting rod, with the upper end of the return spring fixedly connected to the lower end of the adjacent push plate.

[0011] The present invention has the following beneficial effects:

[0012] 1. By setting up a take-up roller with knurled grooves, when the take-up roller is taking up the down during rotation, the lifting rod inside the fixed roller can be raised and lowered continuously, thereby driving the magnetic plate to continuously enter and exit the spiral coil. This intermittently energizes the conductive spring, causing the conductive spring to continuously extend and retract, and driving the deflector plate to continuously move the taken-up down, knocking out the dust inside the down. Finally, the dust is absorbed by the adsorption mechanism, which can prevent the down with a large amount of dust from being taken up.

[0013] 2. By setting up electrode plates, metal adsorption plates, and metal scrapers, when the spiral coil supplies power to the electrode plates through the power supply circuit, static charge can be accumulated on the electrode plates, and the metal adsorption plates opposite them can be induced to become charged. In this way, the dust can be attracted by static electricity and removed. At the same time, the metal scraper can scrape the dust adsorbed on the metal adsorption plates into the dust collection box, so that each metal adsorption plate can be cycled to perform dust collection.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Reference Figure 1-3 An automatic down pillow winding device includes a winding box 1, a winding roller 6 rotatably connected to the inner wall of the winding box 1, a limiting plate 2 fixedly connected to the inner wall of the winding box 1, a conductive spring 3 fixedly connected to the upper end of the limiting plate 2, a lever plate 4 fixedly connected to the upper end of the conductive spring 3, a dust-collecting housing 7 fixedly connected to the inner wall of the winding box 1, an adsorption mechanism for adsorbing dust installed inside the dust-collecting housing 7, a knurled groove 11 opened on the side wall of the winding roller 6, a fixed roller 12 fixedly connected to the inner wall of the winding box 1, and the fixed roller 12 extending into the knurled groove 11, a lifting groove 13 opened on the side wall of the fixed roller 12, a lifting rod 15 slidably connected in the lifting groove 13, two return springs 10 fixedly connected to the upper end of the fixed roller 12, two push plates 29 fixedly connected to the side wall of the lifting rod 15, and the upper end of the return spring 10 fixedly connected to the lower end of the adjacent push plate 29.

[0020] A magnetic plate 16 is fixedly connected to the side wall of the lifting rod 15, and a roller 22 is rotatably connected to the side wall of the lifting rod 15. The roller 22 is rolled on the inner wall of the knurled groove 11. A spiral coil 14 is installed in the lifting groove 13, and the spiral coil 14 is electrically connected to the conductive spring 3.

[0021] The adsorption mechanism includes a rotating wheel 8 rotatably connected to the inner wall of the take-up box 1, an electrode plate 23 mounted on the inner wall of the dust collection housing 7, and multiple metal adsorption plates 24 fixedly connected to the side wall of the rotating wheel 8. The spiral coil 14 supplies power to the electrode plate 23 through a power supply circuit. It should be noted that the rotating wheel 8 and the take-up roller 6 can be connected by two synchronous pulleys and a synchronous belt. When the take-up roller 6 is driven to rotate by a motor, the rotating wheel 8 can also be driven to rotate synchronously.

[0022] Furthermore, after the electrode plate 23 is energized, a large amount of static charge accumulates on it, which causes the metal adsorption plate 24 opposite to it to be induced to become charged, so that the metal adsorption plate 24 accumulates static charge with the opposite charge to that on the electrode plate 23.

[0023] A dust collection box 25 is fixedly connected to the lower end of the vacuum cleaner housing 7, and the dust collection box 25 is connected to a purification chamber 9 through a conveying pipe 27. A filter screen 26 is fixedly installed inside the purification chamber 9, and a negative pressure mechanism is connected to the purification chamber 9 to draw air into the purification chamber 9. A metal scraper 28 is fixedly connected to the inner wall of the vacuum cleaner housing 7, and the metal scraper 28 is grounded through a wire. It should be noted that when the metal adsorption plate 24 comes into contact with the metal scraper 28, it is equivalent to grounding, which can make the static electricity on the metal adsorption plate 24 disappear.

[0024] The negative pressure mechanism includes a negative pressure plate 19, an air intake pipe 20, and an exhaust pipe 21. A negative pressure groove 17 is provided on the side wall of the fixed roller 12. The negative pressure plate 19 is slidably connected in the negative pressure groove 17. Both the air intake pipe 20 and the exhaust pipe 21 are connected to the negative pressure groove 17. An air intake one-way valve is installed in the air intake pipe 20, and an exhaust one-way valve is installed in the exhaust pipe 21. It should be noted that the air intake one-way valve in the air intake pipe 20 only allows air to flow from the air intake pipe 20 into the negative pressure groove 17, while the exhaust one-way valve restricts air to flow only unidirectionally from the negative pressure groove 17 to the exhaust pipe 21. Therefore, when the negative pressure plate 19 moves up and down, it can only draw air from the air intake pipe 20 and can only exhaust air from the exhaust pipe 21.

[0025] The negative pressure plate 19 is fixedly connected to the lifting rod 15 via the connecting rod 18, and the end of the suction pipe 20 away from the negative pressure tank 17 is connected to the purification box 9. It should be noted that, as... Figure 3 As shown, the connecting rod 18 passes through the inner top of the negative pressure groove 17, so that the inner top of the negative pressure groove 17 can communicate with the lifting groove 13, so that the upper space of the negative pressure plate 19 is not in a sealed state, and the negative pressure plate 19 can move up and down without obstruction.

[0026] In this invention, the winding roller 6 and the rotating wheel 8 can be driven to rotate simultaneously by a motor and a synchronous pulley. The winding roller 6 can wind up the down fabric 5. During the rotation of the winding roller 6, the uneven parts on the inner wall of the knurling groove 11 will continuously pass through the roller 22. When the protruding part on the inner wall of the knurling groove 11 contacts the roller 22, it can press down the roller 22 and force the lifting rod 15 to move down. When the concave part on the inner wall of the knurling groove 11 passes through the roller 22, the return spring 10 can push the push plate 29 and the lifting rod 15 to move up and reset. Therefore, when the winding roller 6 continues to rotate, the lifting rod 15 will also continuously move up and down under the combined action of the return spring 10 and the roller 22. The magnetic plate 16 on the side wall of the lifting rod 15 will continuously enter and exit the spiral coil 14, causing the magnetic flux in the spiral coil 14 to continuously change, thereby generating an induced current. When the magnetic plate 16 is completely away from the spiral coil 14, the magnetic flux in the spiral coil 14 will continuously change, thereby generating an induced current. After the spiral coil 14 is turned on, the magnetic flux inside the spiral coil 14 is zero, and the induced current also disappears. Therefore, during the continuous rotation of the take-up roller 6, the spiral coil 14 can intermittently generate an induced current. Whenever the spiral coil 14 generates an induced current, the conductive spring 3 is energized. When the conductive spring 3 is energized, since the current flowing through each coil of the spring is the same, according to the principle that currents in the same direction attract each other, the coils of the conductive spring 3 attract each other and stick together. This causes the conductive spring 3 to contract and pull the dial plate 4 down. When the spiral coil 14 stops generating an induced current, the conductive spring 3 is de-energized. After the conductive spring 3 is de-energized, the attraction between the coils of the spring disappears, and the conductive spring 3 no longer contracts but naturally extends back. This pushes the dial plate 4 up and makes the dial plate 4 pat the down fabric 5 above once, causing the dust inside the down fabric 5 to be discharged.

[0027] Furthermore, the induced current continuously generated by the spiral coil 14 can be amplified and integrated by the power supply circuit and then supplied to the electrode plate 23. After the electrode plate 23 is energized, a large amount of static charge accumulates on it, causing the metal adsorption plate 24 opposite to it to be induced to become charged. This results in the accumulation of static charge on the metal adsorption plate 24 with the opposite charge to that on the electrode plate 23. As the rotating wheel 8 continues to rotate, the metal adsorption plate 24 with static charge is rotated closer to the down fabric 5. When the dust is discharged, the charged metal adsorption plate 24 can adsorb the dust onto it. (Refer to...) Figure 2 When the metal adsorption plate 24, which has adsorbed dust, rotates to the position where it passes the metal scraper 28, the metal scraper 28 comes into contact with the metal adsorption plate 24. Since the metal scraper 28 is grounded through a wire, the static electricity on the metal adsorption plate 24 disappears at this time. At the same time, the metal scraper 28 can scrape the dust on the metal adsorption plate 24 into the dust collection box 25.

[0028] Furthermore, the lifting rod 15 will also drive the negative pressure plate 19 to move up and down synchronously via the connecting rod 18. When the negative pressure plate 19 moves up, a negative pressure can be generated on its lower side, which can draw the dust and air in the dust collection box 25 into the purification box 9 along the conveying pipe 27. The dust will be filtered and trapped by the filter screen 26 in the purification box 9, and the air will be drawn into the negative pressure groove 17 through the suction pipe 20. When the negative pressure plate 19 moves down, the air in the negative pressure groove 17 can be discharged through the exhaust pipe 21. Therefore, when the negative pressure plate 19 moves up and down, it can continuously generate negative pressure and continuously draw the dust in the dust collection box 25 into the purification box 9 through the conveying pipe 27. Therefore, it is only necessary to clean the purification box 9 periodically.

[0029] In summary, this device intermittently energizes the conductive spring 3, causing it to continuously extend and retract, which in turn drives the lever 4 to continuously move the rolled-up down fabric 5, dislodging the dust inside the down. Finally, the dust is adsorbed away by the adsorption mechanism, thus preventing the down with a large amount of dust from being rolled up.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
