Description

Technical Field

[0001] This utility model relates to the field of cotton filling technology, and in particular to a cotton filling device for sofa backrests. Background Technology

[0002] As a type of home furnishing, sofas require a certain amount of fluffy cotton balls to be filled into their cavity during the production process. The filling of sponge increases the comfort of the sofa. In the production process, a filling machine is usually used to fill the sofa with sponge or cotton.

[0003] In the prior art, such as the utility model patent document with authorization announcement number "CN 214570725 U" and patent name "Clean and Dust-Free Sofa Cotton Filling Device", a clean and dust-free sofa cotton filling device is disclosed, including a disc worktable and a dustproof cover; the dustproof cover is provided with a feed port; the disc worktable is provided with a discharge port; a cotton gripping device is rotatably provided on the disc worktable; a discharge air duct is provided below the disc worktable; the discharge port is connected to the discharge air duct; a drive mechanism is installed at the bottom of the discharge air duct; the drive mechanism is connected to a plug; the plug is used to seal and open the discharge port; a blower is provided at one end of the discharge air duct; and a discharge pipe is provided at the other end of the discharge air duct.

[0004] The aforementioned patent document improves efficiency by directly filling the sofa with cotton through the cooperation of the drive mechanism and the blower. However, each time the sofa fabric is filled with cotton, the filling port size varies due to the different specifications of the sofa fabric during the cutting process. Each time, the filling operator has to hold the filling port on the sofa fabric by hand. Over time, the operator is prone to fatigue due to high-intensity work, causing the filling port to fall off the filling nozzle. This results in the entire set of filling amount not reaching the complete standard, causing quality problems in the sofa production and increasing the workload of the operators.

[0005] Therefore, it is necessary to provide a sofa backrest filling device to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a sofa backrest cotton filling device, which solves the problems in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a sofa backrest filling device, including a filling machine body. The output end of the filling machine body is connected to a filling gun via a flexible hose. A pushing ring is slidably sleeved on the surface of the filling gun. A second mounting seat is provided on the circumferential side of the filling gun, and a second support rod is movably installed inside the second mounting seat. A first mounting seat is provided on the circumferential side of the pushing ring, and a first support rod is movably installed inside the first mounting seat. The first and second support rods are movably connected by a pin. An external thread is provided on the outer surface of the filling gun, and a threaded cylinder is spirally connected to the circumferential side of the filling gun. A compression plate is provided at one end of the threaded cylinder. The device comprises a filling gun, external thread, threaded cylinder, compression plate, and pushing ring. The coordinated use of the moving ring, the first mounting base, the first support rod, the second mounting base, and the second support rod ensures that the filling gun is fixed to the inlet when the filling machine body is filling the back of the sofa, improving the stability during filling. During operation, the operator inserts one end of the filling gun into the filling inlet, then rotates the threaded cylinder, causing the screw cylinder to move the extrusion disc on the filling gun. The extrusion disc then moves the push ring, and under the action of the first mounting base, the second mounting base, the first mounting rod, and the second mounting rod, the extrusion disc contacts the first support rod across the sofa back. Finally, the limiting ring clamps and fixes the sofa cover, eliminating the need for manual support. This method is simple to operate and prevents the sofa from falling off.

[0008] Preferably, a limiting ring is provided on the peripheral side of the filling gun. By providing the limiting ring, the movement of the pushing ring can be limited, which facilitates the contact between the subsequent squeezing ring and the first support rod, and facilitates the filling of the sofa back with cotton.

[0009] Preferably, the outer diameter of the limiting ring is larger than the outer diameter of the pushing ring. By setting the outer diameter of the limiting ring to be larger than the outer diameter of the pushing ring, it is easier for the limiting ring to block the pushing ring.

[0010] Preferably, the inner diameter of the push ring is larger than the outer diameter of the filling gun. By setting the inner diameter of the push ring to be larger than the outer diameter of the filling gun, it is easier for the push ring to slide on the filling gun.

[0011] Preferably, there are two first mounting seats, and the two first mounting seats are symmetrically installed about their center lines. By setting two first mounting seats, it is convenient to install two sets of first support rods, thereby improving the stability of the cotton filling gun during cotton filling.

[0012] Preferably, a controller is installed on the outer surface of the cotton filling machine body. By setting the controller, it is convenient to control the electrical components inside the cotton filling machine body.

[0013] Compared with related technologies, the sofa backrest cotton filling device provided by this utility model has the following beneficial effects:

[0014] Compared with existing technologies, this sofa backrest filling device, through the coordinated use of a filling gun, external thread, threaded cylinder, extrusion disc, push ring, first mounting base, first support rod, second mounting base, and second support rod, ensures that the filling gun is fixed to the inlet when filling the sofa backrest, improving stability during filling. During operation, the operator inserts one end of the filling gun into the filling inlet, then rotates the threaded cylinder, causing the extrusion disc to move on the filling gun. The extrusion disc then moves the push ring, and under the action of the first and second mounting bases, the extrusion disc contacts the first support rod across the sofa backrest. Finally, the limiting ring clamps and fixes the sofa backrest, eliminating the need for manual support. This method is simple to operate, prevents detachment, and the limiting ring restricts the movement of the push ring, facilitating subsequent contact between the extrusion ring and the first support rod, thus facilitating the filling of the sofa backrest.

A first mounting seat 12 is provided on the periphery of the pushing ring 11. A first support rod 7 is movably installed inside the first mounting seat 12. The first support rod 7 and the second support rod 8 are movably connected by a pin. An external thread 5 is provided on the outer surface of the filling gun 4. A threaded cylinder 6 is spirally connected to the periphery of the filling gun 4. A compression plate 10 is provided at one end of the threaded cylinder 6. The device comprises a filling gun 4, an external thread 5, a threaded cylinder 6, a compression plate 10, a pushing ring 11, and a second support rod 8. The combined use of mounting base 12, first support rod 7, second mounting base 9, and second support rod 8 allows the filling gun 4 to be fixed to the inlet when the filling machine body 1 is filling the back of the sofa, improving the stability during filling. During operation, the operator inserts one end of the filling gun 4 into the filling inlet, then rotates the threaded cylinder 6, causing the screw plate 10 to move on the filling gun 4. The screw plate 10 then moves the push ring 11. Under the action of the first mounting base 12, second mounting base 9, first mounting rod, and second mounting rod, the screw plate 10 contacts the first support rod 7 across the sofa back. Finally, the limiting ring 13 clamps and fixes the sofa cover, eliminating the need for manual support. This method is simple to operate and prevents the sofa from falling off.

[0026] The working principle of the sofa backrest cotton filling device provided by this utility model is as follows:

[0027] In operation, the operator inserts one end of the filling gun 4 into the filling port, then rotates the threaded cylinder 6, causing the compression plate 10 to move on the filling gun 4. The compression plate 10 then moves the pushing ring 11. Under the action of the first mounting seat 12, the second mounting seat 9, the first mounting rod, and the second mounting rod, the compression plate 10 contacts the first support rod 7 across the sofa back. Then, under the action of the limiting ring 13, the sofa back is clamped and fixed, eliminating the need for manual support. This method is simple to operate and prevents the sofa from falling off. The limiting ring 13 helps to limit the movement of the pushing ring 11, facilitating the contact between the compression ring and the first support rod 7, and making it easier to fill the sofa back with cotton.

[0028] Compared with related technologies, the sofa backrest cotton filling device provided by this utility model has the following beneficial effects:

[0029] This sofa backrest filling device, through the coordinated use of a filling gun 4, an external thread 5, a threaded cylinder 6, a compression disc 10, a push ring 11, a first mounting base 12, a first support rod 7, a second mounting base 9, and a second support rod 8, ensures that when the filling machine body 1 fills the sofa backrest, the filling gun 4 is fixed to the inlet, improving the stability during filling. During operation, the operator inserts one end of the filling gun 4 into the filling inlet, then rotates the threaded cylinder 6, causing it to move the compression disc 10 on the filling gun 4, thus compressing the filling material. The disc 10 drives the push ring 11 to move, and then, under the action of the first mounting seat 12, the second mounting seat 9, the first mounting rod and the second mounting rod, the extrusion disc 10 contacts the first support rod 7 through the sofa back. Then, under the action of the limiting ring 13, the sofa outer skin is clamped and fixed, so that no manual support is required. This method is simple to operate and avoids the phenomenon of falling off. By setting the limiting ring 13, it is easy to limit the movement of the push ring 11, which facilitates the subsequent contact between the extrusion ring and the first support rod 7, and facilitates the filling of cotton into the sofa back.
