DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] An embodiment of the present utility model provides a continuous production line for pillow cores, as Figure 1 shown, which includes a preforming mechanism 1, a hot pressing and forming mechanism 2, a cooling and shaping mechanism 3, a cutting mechanism 4, a blanking mechanism 5, and a controller electrically connected to the preforming mechanism 1, the hot pressing and forming mechanism 2, the cooling and shaping mechanism 3, the cutting mechanism 4, and the blanking mechanism 5 respectively.

[0030] In this embodiment, as Figures 2-3 shown, the preforming mechanism 1 includes a base 11. An installation frame 12 is installed on the top of the base 11. A storage cylinder 13 is installed on the top of the installation frame 2. The storage cylinder 13 is inclined downward along the front-to-back direction. The storage cylinder 13 is a hollow cylinder. A first feed port and a first discharge port are respectively provided at the front end and the rear end of the storage cylinder 13. A valve 14 for opening or closing the first discharge port is installed at the first discharge port. A vibration assembly 15 for driving the storage cylinder 13 to vibrate is installed on the installation frame 12. The vibration assembly 15 is a vibration motor or a hammer. Cotton wadding can enter the interior of the storage cylinder 13 through the first feed port. At the same time, the discharge port is closed by the valve 14 to prevent the cotton wadding inside the storage cylinder 13 from being discharged through the first discharge port. The vibration assembly 15 can drive the storage cylinder 13 to vibrate, so that the cotton wadding inside the storage cylinder 13 is vibrated and compressed into a strip shape. After the cotton wadding is compressed, the valve 14 can be opened, so that the compressed cotton wadding is discharged from the interior of the storage cylinder 13 through the first discharge port.

[0031] In this embodiment, a suction pipe 16 is provided at the first feed port. The suction pipe 16 is communicated with the discharge port of a suction pump. The scattered cotton wadding can be blown into the interior of the storage cylinder 13 through the suction pump to automatically add cotton wadding to the interior of the storage cylinder 13. At the same time, the storage cylinder 3 is rectangular parallelepiped-shaped and both sides are of a net structure. The gas blown into the interior of the storage cylinder 3 can be quickly discharged through both sides of the storage cylinder 3. At the same time, when the gas is discharged, the cotton wadding can be extended towards both sides of the storage cylinder 3, so that the cotton wadding can be laid flat inside the storage cylinder 3, so as to initially form the width of the cotton wadding.

[0032] In this embodiment, an auxiliary frame 7 is installed between the base 1 and the storage cylinder 3. The storage cylinder 3 can be more firmly installed on the base 1 through the auxiliary frame 7, so as to prevent the connection between the storage cylinder 3 and the installation frame 2 from being disconnected due to the vibration of the storage cylinder 3 and improve the service life.

[0033] In this embodiment, an air shock pad 8 is installed between the base 1 and the mounting bracket 2. The air shock pad 8 prevents the base 1 from vibrating, thereby avoiding the movement of the position of the base 1.

[0034] In this embodiment, a transparent detection window 31 is provided on the upper side wall of the storage cylinder 3. A detection sensor 9 is installed at the transparent detection window 31. The detection sensor 9 is an infrared sensor. The detection sensor 9, the valve 4, and the vibration assembly 5 are respectively electrically connected to the controller. When the storage cylinder 3 is filled with cotton wool, the detection sensor 9 can detect the cotton wool and send a detection signal to the controller. The controller controls the vibration assembly 5 to stop vibrating and simultaneously controls the valve 4 to open, and discharges the preliminarily formed cotton wool through the discharge port.

[0035] In this embodiment, the valve 14 includes a closing plate 141 provided at the discharge port. The closing plate 141 is connected to a driving device 142 for driving the closing plate 141 to move at the discharge port. The driving device 142 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. The driving device 142 can drive the closing plate 141 to move at the first discharge port to open or close the first discharge port. At the same time, the closing plate 141 is installed on the first slider 143. The first slider 143 is slidably provided on the first slide rail 144. The first slide rail 144 is installed on the mounting plate 145. The mounting plate 145 is installed on the storage cylinder 13. The cooperation of the first slide rail 144 and the first slider 143 enables the closing plate 141 to move stably, so that the first discharge port can be opened or closed more stably.

[0036] In this embodiment, as Figures 4-5 shown, the hot pressing and forming mechanism 2 includes a hot air box 21 and a hot air component 22 for supplying hot air into the hot air box 21. A second feed port and a second discharge port are respectively provided on the front and rear sides of the hot air box 21. An upper conveyor belt 23 and a lower conveyor belt 24 are respectively installed above and below the hot air box 21. The bottom of the front end of the upper conveyor belt 23 is inclined downward in the front-to-rear direction. The bottom of the rear end of the upper conveyor belt 23 and the lower conveyor belt 24 are horizontal, so that the gap between the front end of the upper conveyor belt 23 and the front end of the lower conveyor belt 24 gradually decreases in the front-to-rear direction. At the same time, the gap between the rear end of the upper conveyor belt 23 and the rear end of the lower conveyor belt 24 is equal in the front-to-rear direction. The rear end of the storage cylinder 13 is provided between the front end of the upper conveyor belt 23 and the front end of the lower conveyor belt 24. The cotton wool discharged from the storage cylinder 13 can enter from between the front end of the lower conveyor belt 23 and the front end of the lower conveyor belt 24. When the cotton wool is conveyed from between the front end of the upper conveyor belt 23 and the front end of the lower conveyor belt 24 to between the rear end of the upper conveyor belt 23 and the rear end of the lower conveyor belt 24, the upper conveyor belt 23 and the lower conveyor belt 24 can extrude the cotton wool. At the same time, the hot air component 22 can supply hot air into the hot air box 21, so that the cotton wool can be hot-pressed and formed.

[0037] In this embodiment, left and right guide plates 25 and 26 are respectively arranged on the left and right sides between the upper conveyor belt 23 and the lower conveyor belt 24. The gap between the front ends of the left guide plate 25 and the right guide plate 26 gradually decreases in the front-to-rear direction, and the gap between the rear ends of the left guide plate 25 and the right guide plate 26 is equal in the front-to-rear direction, so as to hot-press and form the cotton wadding to a certain width.

[0038] It should be noted that the distance between the upper conveyor belt 3 and the lower conveyor belt 4 is adjustable, and the distance between the left guide plate 5 and the right guide plate 6 is adjustable. Therefore, the thickness and width of the cotton wadding can be adjusted.

[0039] In this embodiment, the hot air assembly 22 includes a heating device 221 and a first blower 222. The heating device 221 is installed inside the upper conveyor belt 23. The exhaust duct of the first blower 222 is communicated with the heating device 221. The air blown out by the first blower 222 can enter the heating device 221 for heating. At the same time, the upper conveyor belt 23 is provided with second air permeable holes 231. The hot air can pass through the upper conveyor belt 23 and enter between the upper conveyor belt 23 and the lower conveyor belt 24 to heat and shape the cotton wadding. At the same time, the intake duct of the first blower 222 is arranged inside the lower conveyor belt 24. The lower conveyor belt 24 is provided with third air permeable holes 241. The hot air between the upper conveyor belt 23 and the lower conveyor belt 24 can pass through the lower conveyor belt 24 and enter the inside of the lower conveyor belt 24. The hot air inside the lower conveyor belt 24 can flow back to the first blower 222 through the intake duct of the blower 222. The heating effect is good, and at the same time, the hot air can be circulated, which is energy-saving and environmentally friendly.

[0040] In this embodiment, the heating device 221 includes a heating box 2211 installed inside the upper conveyor belt 23. The heating box 2211 is communicated with the exhaust duct of the first blower 222. Electric heating tubes 2212 are installed inside the heating box 2211. The bottom of the heating box 2211 is provided with first air permeable holes 22111. The air blown out by the first blower 222 can enter the heating box 2211. The air inside the heating box 2211 can be heated by the electric heating tubes 2212, and the heated air can be discharged through the third air permeable holes 22111 at the bottom of the heating box 2211.

[0041] In this embodiment, as Figures 6-7 shown, the cooling and shaping mechanism 3 includes a cooling box 31 and an air extraction assembly 32 for extracting the hot air inside the cooling box 31. The cooling box 31 is arranged at the rear side of the hot air box 21. A third feed port and a third discharge port are respectively arranged at the front side and the rear side of the cooling box 31. A conveyor belt 33 is arranged inside the cooling box 31. The hot-pressed and formed cotton wadding can be conveyed onto the conveyor belt 33. Through the conveyor belt 33, the hot-pressed and formed cotton wadding can be conveyed inside the cooling box 31. At the same time, the heat generated by the hot-pressed and formed cotton wadding will enter the cooling box 31. Through the air extraction assembly 32, the hot air inside the cooling box 31 can be extracted to cool and shape the hot-pressed and formed cotton wadding.

[0042] In this embodiment, the conveyor belt 33 is provided with ventilation holes 331, and hot air can pass through the conveyor belt 33 and enter the inside of the conveyor belt 33. The air extraction assembly 32 includes a second fan. The air inlet pipe of the second fan is arranged inside the conveyor belt 33, and the hot air entering the inside of the conveyor belt 33 can be discharged through the second fan. At the same time, an air inlet hole 311 is provided at the top of the cooling box 31, and the outside air can enter the inside of the cooling box 31 through the air inlet hole 311, so the cooling effect is good.

[0043] In this embodiment, the cutting mechanism 4 includes a cutting knife 41. The cutting knife 41 is a hot cutting knife. The cutting knife 41 is arranged at the rear side of the cooling box 31. The cutting knife 41 is connected to a lifting assembly 42 for driving the cutting knife 41 to lift. The lifting assembly 42 is one of a cylinder, a hydraulic cylinder or an electric telescopic rod. The cutting knife 41 can be driven to lift by the lifting assembly 42 to cut the cotton wool after cooling and shaping. The cutting quality is high. At the same time, the cutting knife 41 is installed on a second slider 43. The second slider 43 is slidably arranged on a second slide rail 44. The second slide rail 44 is installed on a mounting frame 45. The mounting frame 45 is a gantry. The mounting frame 45 is installed at the rear side of the conveyor belt 33. The cutting knife 41 can be stably lifted by the cooperation of the second slider 43 and the second slide rail 44.

[0044] In this embodiment, the blanking mechanism 5 includes a first blanking table 51. The first blanking table 51 is arranged at the rear side of the cutting knife 41. A second detection sensor 52 is installed at the right end of the rear side of the first blanking table 51. The second detection sensor 52 is an infrared sensor. The cotton wool after cooling and shaping is conveyed to the first blanking table 51 through the conveyor belt 33. When the cotton wool is conveyed to the second detection sensor 52, the second detection sensor 52 detects the cotton wool, and the second detection sensor 52 sends a signal to the controller and controls the lifting assembly 42 to drive the cutting knife 41 to descend to cut the cotton wool into pieces. A first push rod 53 is arranged above the first blanking table 51. The first push rod 53 is connected to a first driving assembly 54 for driving the first push rod 53 to move left and right.

[0045] Specific principle: During use, the vibration component 15 can drive the vibrating storage cylinder 13, causing the cotton wadding inside the storage cylinder 13 to vibrate and compress into strips. After the cotton wadding is compressed, the valve 14 can be opened, enabling the compressed cotton wadding to be discharged from the inside of the storage cylinder 13 through the first discharge port. The cotton wadding discharged from the storage cylinder 13 can enter between the front ends of the lower conveyor belt 23 and the lower conveyor belt 24. When the cotton wadding is conveyed from between the front ends of the upper conveyor belt 23 and the lower conveyor belt 24 to between the rear ends of the upper conveyor belt 23 and the lower conveyor belt 24, the upper conveyor belt 23 and the lower conveyor belt 24 can squeeze the cotton wadding. At the same time, the hot air component 22 can supply hot air into the hot air box 21, thereby thermally pressing the cotton wadding into shape. The thermally pressed cotton wadding can be conveyed onto the conveyor belt 13. Through the conveyor belt 13, the thermally pressed cotton wadding can be conveyed inside the cooling box 11. At the same time, the heat generated by the thermally pressed cotton wadding will enter the cooling box 11. The hot air inside the cooling box 11 can be extracted by the air extraction component 12 to cool and shape the thermally pressed cotton wadding. The cooled and shaped cotton wadding is conveyed to the first blanking table 31 through the conveyor belt 13. When the cotton wadding is conveyed to the detection sensor 32, the detection sensor 32 detects the cotton wadding. The detection sensor 32 sends a signal to the controller and controls the lifting component 22 to drive the cutting knife 21 to descend to cut the cotton wadding into pieces. The first driving component 34 can drive the first push rod 33 to move left and right to push the cut cotton wadding pieces onto the second blanking table 35. The second driving component 37 can drive the second push rod 36 to move back and forth to push the cut cotton wadding pieces into the blanking nozzle 38 and slide along the blanking nozzle 38 into the non-woven fabric bag for packaging.
