[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following describes a cotton-filling device for processing sofa cushions according to an embodiment of the present invention, with reference to the accompanying drawings.

[0026] like Figures 1-6 As shown, the cotton filling device for processing sofa cushions according to this utility model embodiment may include: a frame 1, a cotton filling machine body 2, a conveying mechanism 3, a drying mechanism 4, a collection box 5, and a feeding mechanism 6.

[0027] The conveying mechanism 3 is located on the upper part of the frame 1.

[0028] Understandably, the conveying mechanism 3 is used to transport undried cotton from the side away from the main body 2 of the cotton filling machine to the side closer to the main body 2 of the cotton filling machine.

[0029] The drying mechanism 4 is located on the upper part of the conveying mechanism 3. The drying mechanism 4 includes: a drying box 401, a hot air blower 402, and a filter section 403.

[0030] The drying chamber 401 is installed on the upper part of the frame 1, the hot air blower 402 is installed on the upper part of the drying chamber 401 and its air outlet is connected to the inside of the drying chamber 401, and the filter 403 is located inside the drying chamber 401.

[0031] It should be noted that the length of the drying box 401 described in this embodiment is less than the length of the conveying mechanism 3 and the frame 1, which makes it easier for the staff to load materials onto the conveying mechanism 3. The hot air blower 402 can heat the air and blow hot air into the drying box 401 to dry the cotton during the conveying process. The filter part 403 is used to block fine cotton fibers.

[0032] Collection box 5 is installed on one side of frame 1.

[0033] Understandably, collection box 5 is used to collect the dried cotton.

[0034] The feeding mechanism 6 is located between the collection box 5 and the main body 2 of the cotton filling machine.

[0035] It should be noted that the main body 2 of the cotton filling machine is an existing device on the market, and its connection method is also existing technology. After the cotton enters the main body 2 of the cotton filling machine, it is made fluffy by mechanical stirring, and then the cotton is filled into the sofa cushion cover by the force of the air to complete the filling process.

[0036] Specifically, in a sofa cushion manufacturing plant, this sofa cushion filling device is used to fill the sofa cushion cover with cotton.

[0037] The staff first put the untreated cotton into one end of the conveyor mechanism 3, and started the conveyor mechanism 3 to transport the cotton to one side of the cotton filling machine body 2. The hot air fan 402 was started, and after the cotton entered the drying box 401, the hot air could quickly dry the cotton. During the air circulation process, the filter part 403 could block the small cotton fibers blown up.

[0038] After drying, the conveyor mechanism 3 continues to transport the cotton and it falls into the collection box 5. The feeding mechanism 6 is started to draw the cotton into the main body 2 of the filling machine. The staff puts the sofa cushion cover on the filling head and starts the filling machine 2 to fill the sofa cushion with cotton.

[0039] In one embodiment of this utility model, such as Figure 2As shown, the conveying mechanism 3 includes multiple drive rollers 301, belts 302, multiple baffles 303, and a motor 304.

[0040] Multiple drive rollers 301 are rotatably connected between the front and rear walls at both ends of the frame 1. A belt 302 is sleeved between the multiple drive rollers 301. Multiple baffles 303 are respectively arranged on the outside of the belt 302. The baffles 303 are evenly spaced. A motor 304 is mounted on the frame 1 and its output end is connected to one side of the drive roller 301.

[0041] It should be noted that when the staff feeds the cotton, they place a small amount of cotton between the two baffles 303 each time. The speed at which the motor 304 drives the transmission roller 301 to rotate is set according to the moisture content of the cotton. For example, when the moisture content of the cotton is greater than 12%, the time for the transmission roller 301 to rotate one revolution is set to 5 seconds, so that the cotton moves slowly in the drying box 401 and the drying time is extended.

[0042] In one embodiment of this utility model, such as Figure 1 and Figure 6 As shown, the lower ends of both sides of the drying box 401 are provided with material guide grooves 4011, which are adapted to the baffles 303.

[0043] It should be noted that the length of the guide trough 4011 described in this embodiment is the distance between the two baffles 303. The baffles 303 and the guide trough 4011 maintain a small distance, so that the baffles 303 can pass through normally. Thus, the guide trough 4011 and the baffles 303 can block and limit the cotton, preventing the hot air from blowing the cotton out of the drying box 401 during drying.

[0044] In one embodiment of this utility model, such as Figure 1 As shown, exhaust ports 4012 are provided in the middle of both sides of the drying oven 401.

[0045] Understandably, the exhaust port 4012 is used to discharge gas and achieve air circulation inside the drying oven 401.

[0046] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the filter section 403 includes multiple filter plates 4031, multiple locking blocks 4032, multiple locking slots 4033, multiple handles 4034, and multiple scrapers 4035.

[0047] Multiple filter plates 4031 are respectively arranged on both sides inside the drying chamber 401 and extend through the upper end of the drying chamber 401. The filter plates 4031 are located on the upper part of the guide trough 4011. Multiple locking blocks 4032 are respectively arranged on both sides of the filter plates 4031. Multiple locking slots 4033 are respectively opened on the inner wall of the drying chamber 401 corresponding to the locking blocks 4032. The locking blocks 4032 and the locking slots 4033 are adapted to each other. Multiple handles 4034 are respectively connected to the upper part of the filter plates 4031. Multiple scrapers 4035 are respectively installed on the upper side inside the drying chamber 401. The scrapers 4035 are in contact with the surface of the filter plates 4031.

[0048] It should be noted that the filter plate 4031 is attached to the inner wall of the drying chamber 401. The filter plate 4031 can block the fine cotton fibers blown up, preventing them from being blown out of the drying chamber 401 through the exhaust port 4012. The filter plate 4031 can be removed from the inside of the drying chamber 401 for cleaning through the handle 4034.

[0049] Specifically, when the exhaust rate of the exhaust port 4012 is observed to decrease, the filter plate 4031 is pulled upward by the handle 4034. During the upward movement of the filter plate 4031, the scraper 4035 scrapes off the cotton lint attached to the surface of the filter plate 4031, thus performing a preliminary cleaning of the filter plate 4031. After removing the filter plate 4031, the staff cleans the filter holes.

[0050] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the feeding mechanism 6 includes a blower 601 and a feeding pipe 602.

[0051] The exhaust fan 601 is installed on one side of the collection box 5, and the air inlet is connected to the inside of the collection box 5. One end of the feed pipe 602 is connected to the exhaust fan 601, and the other end is connected to the main body 2 of the cotton filling machine.

[0052] It should be noted that the feed pipe 602 described in this embodiment is a telescopic flexible hose. After the cotton is dried, it will fall into the collection box 5 through the conveyor belt 302. At this time, the exhaust fan 601 is started in conjunction with the feed pipe 602 to draw the cotton into the main body 2 of the cotton filling machine.

[0053] In summary, the cotton filling device for sofa cushion processing of this utility model allows the cotton to pass through a drying mechanism to remove moisture before entering the filling machine body. This makes the cotton lighter, reduces the adhesion between cotton fibers, facilitates effective fluffing of the cotton, improves the uniformity of filling, and saves production costs.
