Description

Technical Field

[0001] This utility model belongs to the field of cotton filling equipment, specifically relating to a cotton filling device, and more particularly to a cotton filling device that can be used to fill filling materials such as open cotton, fiber balls, pearl cotton and down. Background Technology

[0002] In the manufacturing process of cotton-padded clothing, filling is a crucial step. Existing filling devices often encounter some technical difficulties during operation, especially when filling fiber balls and opening the cotton. The filling material is prone to tangling with the beaters, and the filling materials can also become entangled with each other due to static electricity and friction. This results in the filling material becoming dense, with more particles, and reduced fluffiness, affecting the fluffiness and softness of the cotton-padded clothing, making it lack the necessary comfort and warmth.

[0003] Numerous attempts have been made to ensure the uniform dispersion of filling materials and maintain their fluffiness and softness. For example, Chinese patent document CN117502754A discloses a down filling process for garment fabric processing. This process increases the down storage capacity within a box by applying pressure, and then disperses the down within the box using rotating pins. While this patent's use of rotating pins helps to break up any sticky filling material, prolonged stirring within the box can cause the filling materials to become entangled, reducing their fluffiness and softness, especially for heavier filling materials like open cotton or pearl cotton.

[0004] For example, Chinese patent CN221902545U discloses a down filling device for down jackets. A first fan blows cold air into a box containing down, while a second fan blows hot air into the box via an electric heating grid, creating convection within the box to disperse the down. However, for fillings like open cotton and pearl cotton, which are less lightweight than down, relying solely on the airflow from the upper and lower fans to create convection is insufficient to completely and evenly disperse the filling within the box. Especially after compression, open cotton and pearl cotton often remain clumped together even 24 hours after opening the package, making effective dispersion difficult with airflow alone. This results in insufficient loft and uneven filling. Utility Model Content

[0005] The purpose of this invention is to provide a filling device that allows filling materials such as open cotton, fiber balls, pearl cotton, and down to be evenly dispersed during the filling process, resulting in a fluffy and soft filled product.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a cotton filling device, which includes an upper cotton storage box, a lower cotton storage box, a cotton dispersing mechanism, a stirring mechanism, and a cotton filling mechanism;

[0008] The upper cotton storage box has a cotton inlet on its side wall and at least one stirring mechanism inside, and its bottom is connected to the top of the lower cotton storage box; the lower cotton storage box has at least two stirring mechanisms inside and at least one cotton filling mechanism connected to its side wall.

[0009] The mixing mechanism includes a mixing shaft and multiple sets of mixing beaters, with the mixing beaters fixed on the mixing shaft;

[0010] The cotton distribution mechanism includes an external fan, an air outlet sleeve, and a hose. The air outlet sleeve is located inside the lower cotton storage box and has multiple air outlet holes. One end of the air outlet sleeve is closed. The hose passes through the side wall of the lower cotton storage box and is connected at both ends to the external fan and the unclosed end of the air outlet sleeve, respectively.

[0011] Preferably, the mixing beater includes at least two curved mixing rods distributed circumferentially around the mixing shaft, each mixing rod and the mixing shaft enclosing an empty area;

[0012] The top of the stirring rod is provided with an anti-tangling baffle. Each empty area includes an end partition area covered by the baffle and a middle opening area located outside the baffle. The middle opening area is located between the end partition area and the stirring shaft.

[0013] Preferably, the baffle plate and the stirring rod are integrally formed.

[0014] Preferably, the baffle is flat.

[0015] Preferably, the baffle and the stirring rod are detachably connected.

[0016] Preferably, the baffle is U-shaped and is connected to the stirring rod by bolts.

[0017] Preferably, the area ratio of the end partition region to the area of ​​the empty region is 1:3 to 4.

[0018] Preferably, the distance between two adjacent sets of agitators along the axial direction of the agitator shaft is 10-20 cm.

[0019] Preferably, the center distance between two adjacent air outlets on the air outlet sleeve is less than the distance between two adjacent sets of stirring beaters.

[0020] This invention relates to a cotton filling device in which a cotton-dispersing mechanism provides flowing gas to a stirring mechanism. The stirring mechanism, in conjunction with the cotton-dispersing mechanism, disperses the filling material, resulting in excellent fluffiness and softness. Preferably, the stirring rod of the stirring mechanism has an anti-tangling baffle at its tip to prevent the filling material from tangling and clumping, ensuring the effective dispersion of the filling material by the stirring mechanism and further enhancing its fluffiness and softness, making the filled product more fluffy and soft. This cotton filling device is suitable for filling materials such as open cotton, fiber balls, pearl cotton, and down. Attached Figure Description

Detailed Implementation

[0035] This utility model provides a cotton filling device, such as... Figures 1 to 4 As shown, the cotton filling device includes an upper cotton storage box 1, a lower cotton storage box 2, a stirring mechanism 3, a cotton dispersing mechanism 4, and a cotton filling mechanism 5;

[0036] The upper cotton storage box 1 has a cotton inlet 11 on its side wall and at least one stirring mechanism 3 inside. Its bottom is connected to the top of the lower cotton storage box 2. The lower cotton storage box 2 has at least two stirring mechanisms 3 inside and at least one cotton filling mechanism 5 connected to its side wall.

[0037] The stirring mechanism 3 includes a stirring shaft 31 and multiple sets of stirring beaters 32, with the stirring beaters 32 fixed on the stirring shaft 31;

[0038] The cotton dispersing mechanism 4 includes an external fan 41, an air outlet sleeve 42, and a hose 43. The air outlet sleeve 42 is located inside the lower cotton storage box 2. The air outlet sleeve 42 has multiple air outlet holes 421. One end of the air outlet sleeve 42 is closed. The hose 43 passes through the side wall of the lower cotton storage box 2 and its two ends are connected to the external fan 41 and the unclosed end of the air outlet sleeve 42, respectively.

[0039] In this cotton filling device, the external fan 41 of the cotton dispersing mechanism 4 provides flowing gas. The flowing gas is introduced into the lower cotton storage box 2 through the hose 43 and the air outlet sleeve 42, dispersing the filling material in the lower cotton storage box 2. The stirring mechanism 3 in the lower cotton storage box 2, in cooperation with the cotton dispersing mechanism 4, stirs the dispersed filling material, making the filling material more evenly dispersed and improving the fluffiness and softness of the filling material. This cotton filling device can be used to fill down, as well as to fill open cotton, fiber balls, pearl cotton, and other filling materials that are not as light as down. Without the cotton dispersing mechanism 4, there is no flowing gas in the lower cotton storage box 2. The filling material that is not as light as down is not dispersed by the flowing gas and is prone to clumping together. Under the stirring of the stirring mechanism 3 in the lower cotton storage box 2, the dispersion effect of the filling material is poor.

[0040] For example, refer to Figure 1 In the cotton filling device of this utility model, an agitation mechanism 3 is provided in the upper cotton storage box 1, and two agitation mechanisms 3 are provided in the lower cotton storage box 2. The bottom of the upper cotton storage box 1 is provided with a cover plate that can be opened towards the lower cotton storage box 2. The top of the lower cotton storage box 2 has an open structure facing the cover plate. The agitation shafts 31 of the three agitation mechanisms 3 are aligned axially. The two agitation shafts 31 in the lower cotton storage box 2 are at the same height, rotate in opposite directions, and have the same rotation speed. The lower cotton storage box 2 has two opposing first sidewalls 21. The first sidewalls 21 are parallel to the agitation shafts 31. Each first sidewall 21 corresponds to a cotton filling mechanism 5. Each first sidewall 21 is provided with at least two outlets 22. All outlets 22 are at the same height. Each outlet 22 on the first sidewall 21 is connected to the cotton filling mechanism 5 corresponding to the first sidewall 21 through a corresponding transmission pipe.

[0041] Preferably, in the cotton filling device of this utility model, such as Figure 4 and Figure 5As shown, the mixing beater 32 includes at least two curved mixing rods 321 distributed circumferentially around the mixing shaft 31, each mixing rod 321 and the mixing shaft 31 enclosing an empty area 33;

[0042] The top of the stirring rod 321 is provided with an anti-tangling baffle 322. Each empty area 33 includes an end partition area 331 covered by the baffle 322 and an intermediate opening area 332 located outside the baffle 322. The intermediate opening area 332 is located between the end partition area 331 and the stirring shaft 31.

[0043] It is understandable that the tip of the stirring rod 321 is the end of the stirring rod 321 furthest from the stirring shaft 31. (Refer to...) Figure 4 The top of the upper stirring rod 321 is its uppermost point, and the top of the lower stirring rod 321 is its lowermost point.

[0044] As the stirring shaft 31 rotates, the stirring beater 32 disperses the highly agglomerated filler. Since the stirring rod 321 is curved and forms an empty area 33 with the stirring shaft 31, if there is no baffle 322 at the top of the stirring rod 321, some filler material may easily entangle and clump at the top of the stirring rod due to static electricity and friction during the stirring process. This would lead to a decrease in the stirring effect of the stirring rod 321, and the gaps between the stirred filler material would disappear, making the filler material denser. Providing a baffle 322 at the top of the stirring rod 321 prevents the filler material from entangled and clumping in the end baffle area 331 of the stirring rod 321, ensuring the stirring effect of the stirring beater 32 and making the filler material evenly dispersed.

[0045] In the circumferential direction of the stirring shaft 31, the stirring beater 32 includes two, three, or four stirring rods 321, etc. (Refer to...) Figure 3 In this invention, the preferred stirring handle 32 includes four stirring rods 321 distributed circumferentially around the stirring shaft 31. This moderate number ensures good stirring performance. If the stirring handle 32 contains fewer than four stirring rods 321, the spacing between adjacent stirring rods on the circumference of the stirring shaft 31 will be too large, leading to uneven stirring. If the stirring handle 32 contains more than four stirring rods 321, the design is overly redundant, increasing unnecessary design and material costs. Furthermore, this application does not limit the connection method between the stirring rods 321 and the stirring shaft 31. For example, the stirring rods 321 can be welded to the stirring shaft 31 or integrally formed. Alternatively, the stirring handle 32 may also include a connecting ring, with the stirring rods 321 welded to or integrally formed with the connecting ring, which is fitted onto the stirring shaft 31 and connected by bolts.

[0046] The curved stirring rod 321 can be a right-angled U-shape, a rounded U-shape, or other polygons. In this invention, a rounded U-shape is preferred. Firstly, the branches on both sides of the U-shape can fully contact the filler, more effectively breaking it up compared to other shapes of stirring blades. Secondly, the two branches can generate tearing forces in two directions on the filler, further breaking it up and preventing clumping. Furthermore, compared to a right-angled U-shape, a rounded U-shape, and a right-angled bend, reduces the tangling and clumping of the filler.

[0047] In some embodiments, the baffle 322 and the stirring rod 321 are preferably integrally formed. An integrally formed stirring rod has a stable structure and good sealing performance, which can better guide the flow of the filler material, reduce resistance during the stirring process, and thus improve stirring efficiency. Preferably, the baffle 322 is flat and has a simple structure.

[0048] In some embodiments, the baffle 322 and the stirring rod 321 are preferably detachably connected. For lightweight fillings such as down, the baffle can be quickly removed, and the detachable connection structure allows for quick replacement of damaged baffles or stirring rods, reducing maintenance costs and difficulty.

[0049] Preferably, the baffle 322 is U-shaped and is connected to the stirring rod 321 by bolts. Specifically, refer to... Figure 6 The U-shaped baffle 322 includes two flat plates 3221 and a connecting portion 3222. The two flat plates 3221 are connected by the connecting portion 4221. The flat plates 3221 and the connecting portion 3222 are bent at right angles. The two ends of the connecting portion 3222 are respectively arc-shaped. The stirring rod 321 is sandwiched between the two flat plates 421. The two ends of the connecting portion 3222 abut against the stirring rod. The two flat plates 3221 are parallel to each other and connected to the stirring rod by bolts. In addition, the baffle 322 and the stirring rod 321 can also be connected by snap-fit, riveting, or other methods.

[0050] In some embodiments, the area ratio of the end partition region 331 to the area of ​​the empty region 33 is preferably 1:3 to 4. When the area of ​​the end partition region 331 is small, i.e., the area of ​​the central opening region 332 is large, more dispersed filler material comes into contact with the branches of the mixing handle during the stirring process, resulting in entanglement; when the area of ​​the end partition region 331 is large, i.e., the area of ​​the central opening region 332 is small, the filler material is subjected to greater external force during the stirring process, which easily leads to local accumulation, uneven dispersion, and a tendency to reduce stirring efficiency. In this application, the area ratio of the end partition region 331 to the area of ​​the empty region 33 is more preferably 1:3.3 to 3.8, and more preferably 1:3.5.

[0051] In some embodiments, the spacing between two adjacent sets of agitators 32 along the axial direction of the agitator shaft 31 is preferably 10-20 cm, which can fully disperse the filler. When the spacing is greater than 20 cm, the agitators will not agitate the filler sufficiently, resulting in the agglomerated filler not dispersing and reducing the agitation efficiency; when the spacing is less than 10 cm, the filler in the lower storage box 2 will encounter greater resistance after being agitated by more agitators, and the gaps between the fillers will be eliminated, making them denser instead.

[0052] In some embodiments, preferably, the center distance between two adjacent air outlets 421 on the air outlet sleeve 42 is smaller than the distance between two adjacent sets of stirring beaters 32. When the center distance between two adjacent air outlets on the air outlet sleeve 42 is greater than the distance between two adjacent sets of stirring beaters 32, the gas flow path becomes longer, causing the gas to be unable to fully and directly act on the filler on the stirring beater 32, and the dispersion effect tends to decrease.

[0053] In the cotton filling device of this utility model, the stirring effect of the filling material in the lower cotton storage box 2 is also affected by factors such as the orientation of the air outlet 421, the speed of the flowing gas in the air outlet sleeve 42, the diameter of the air outlet sleeve 42, the rotation speed of the stirring mechanism 3, and the size of the stirring rod 321.

[0054] As a preferred option, refer to Figures 1 to 3 The vent sleeve 42 is lower than the outlet 22 and the stirring shaft 31. When the vent sleeve 42 is not lower than the outlet 22, the loose filler is easily blown away from the outlet 22 by the flowing gas; when the vent sleeve 42 is not lower than the stirring shaft 31, the filler above the stirring beater 32 can be well dispersed, but the filler below the stirring beater 32 is not easily dispersed by the cotton dispersing mechanism.

[0055] Reference Figure 2 The vent sleeve 42 is a U-shaped tube, comprising two straight sections and a bend. The two straight sections are connected by the bend. One end of one straight section is connected to an external fan 41 via a flexible hose 43, and the other end of the other straight section is closed. The length of the straight sections is aligned with the axial direction of the stirring shaft 31. The vent hole 421 is located on the straight section. Figure 1 and Figure 7 The distance between the two straight pipe sections is greater than the distance between the two stirring shafts 31 in the lower cotton storage box 2. The projections of the two stirring shafts 31 in the lower cotton storage box 2 on the bottom surface of the lower cotton storage box 2 are located between the projections of the two straight pipe sections on the bottom surface of the lower cotton storage box 2. The two stirring mechanisms 3 in the lower cotton storage box 2 correspond one-to-one with the adjacent straight pipe sections.

[0056] In this invention, the vent 421 is preferably located in the area of ​​the straight pipe facing the corresponding stirring mechanism 3, ensuring that the flowing gas is directed towards the stirring mechanism. (Refer to...) Figure 7Let m represent the axis of the stirring shaft 31 inside the lower cotton storage box 2, and n represent the center of any air outlet on the straight section of the air outlet sleeve 42. The perpendicular segment between the center n of the air outlet on the straight section and the axis m of the stirring shaft 31 corresponding to that straight section is denoted as L. The angle θ between the perpendicular segment L and the bottom surface of the lower cotton storage box 2 is 30-80°. The angle θ further defines the distribution area of ​​the air outlets 421 on the straight section, thus ensuring that the flowing gas blown out of each straight section can effectively disperse the filler near the corresponding stirring mechanism. Furthermore, the angle θ affects the direction of the circulating air in the lower cotton storage box, thereby affecting the movement direction of the filler. When the angle θ is less than 30°, the filler above the air outlet sleeve 42 tends to accumulate too much, and the flowing gas is not easy to blow away the filler. When the angle θ is greater than 80°, although the flowing gas can disperse the filler, because the flowing gas is closer to the outlet 22 at this time, it is easy to blow the filler away from the outlet 22, and the filling efficiency of the filling machine tends to decrease.

[0057] Preferably, the air velocity of the flowing gas in the vent sleeve 42 is 5–30 m / s. A higher air velocity results in better dispersion of the filler material, but also causes the filler material at the outlet 22 to be blown away, preventing continuous filling by the filling mechanism and hindering smooth filling. When the air velocity is low, the filler material cannot be blown away, and due to continuous stirring by the agitator, it is more prone to entanglement, and the filler material becomes denser due to the elimination of gaps between fibers. More preferably, the air velocity of the flowing gas in the vent sleeve 42 is 10–20 m / s.

[0058] Preferably, the diameter of the vent sleeve 42 is 2–5 cm. The diameter of the vent sleeve has a significant impact on the output airflow rate. The larger the diameter of the vent sleeve, the smaller the airflow rate, and the less likely the filler material is to be blown up; the smaller the diameter of the vent sleeve, the larger the airflow rate, but if the diameter of the vent sleeve is too small, it affects the airflow speed, and the filler material is also not easily blown up. More preferably, the diameter of the vent sleeve 42 is 3.5–4 cm.

[0059] Preferably, the stirring mechanism rotates at a speed of 5–30 r / min. The rotational speed of the stirring mechanism has a significant impact on the degree of entanglement between the fillers. When the same weight of fillers is placed in the lower cotton storage box, when the stirring speed is greater than 30 r / min, the entanglement between the fillers and between the fillers and the stirring handle is more severe, and the gaps between the fillers are more easily eliminated by external force, resulting in a denser filler with lower loft and a harder feel. When the stirring speed is less than 5 r / min, although the entanglement between the fillers and between the fillers and the stirring handle becomes less severe, and the effect of external force on the fillers is also weakened, large clumps of adhering fillers are not easily dispersed under low-speed stirring, and even if the cotton-dispersing mechanism provides flowing air, it cannot sufficiently disperse the fillers. More preferably, the stirring mechanism rotates at a speed of 5–10 r / min.

[0060] Preferably, the rounded U-shaped stirring rod 321 has a width of 2-4 cm and a length of 15-20 cm. When its width is greater than 4 cm, some agglomerated filler will fall from the center of the stirring handle and cannot be dispersed by the stirring handle, resulting in poor dispersion of the filler. When its width is less than 2 cm, the contact area between the stirring rod and the filler is reduced, and the pushing and dispersing effect of the stirring rod on the filler is weakened, affecting the dispersion effect and filling efficiency of the filler. When its length is greater than 20 cm, more filler is easily entangled on the stirring rod handle; when its length is less than 15 cm, the effect of dispersing the filler is poor. The cross-section of the stirring rod 321 is a hollow circle, and the circumference of its outer circumference is greater than the length of the filler fibers, which can prevent the fibers from entangled on the stirring rod. More preferably, the width of the rounded U-shaped stirring rod is 3-4 cm and the length is 16-18 cm.
