Description

Technical Field

[0001] This utility model relates to the field of plush toy production equipment, specifically a plush toy filling machine. Background Technology

[0002] A down filling machine is an automated piece of equipment used in the clothing and home textile industries. It is primarily used to evenly fill the layers of finished products (such as down jackets, quilts, and pillows) with down, cotton, and other filling materials. Its core function is to efficiently disperse and inject the fluffy filling material into pre-set garment or fabric layers using airflow technology, ensuring uniform filling and consistent weight.

[0003] For example, patent announcement number CN221206761U discloses a stuffing machine for plush toys, relating to the field of plush toy production equipment. It includes a stuffing main unit, a stuffing tube, a sliding assembly, and a clamp. One end of the stuffing tube is connected to the stuffing main unit, and the other end extends away from the stuffing main unit to supply stuffing material to the stuffing tube via the stuffing main unit. The sliding assembly includes a clamping sleeve fitted onto the stuffing tube to allow sliding along the length of the stuffing tube. The clamp is held in place by the clamping sleeve on its outer wall. This application has the effect of improving the stuffing efficiency of plush toys and facilitating the stuffing of large or long plush toys.

[0004] However, the filling tube of the filling machine in the above technology does not have an exhaust structure. When the plush toy is filled, the inside is relatively closed. When the filling material enters the plush toy, it increases the internal air pressure, which can easily damage the plush toy. Therefore, the market urgently needs to develop a plush toy filling machine to help people solve the existing problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a plush toy filling machine, comprising a filling platform 1, a filling tube 101 fixedly connected to the upper middle part of the filling platform 1, an exhaust pipe 2 fixedly connected to the upper end of the filling tube 101, a first circular sealing plate 201 fixedly connected to the front end of the exhaust pipe 2, a telescopic air pipe 3 connected to the front end of the exhaust pipe 2, the rear end of the exhaust pipe 2 extending out of the rear end of the upper surface of the filling tube 101, a fixing ring 202 fixedly connected to the middle part of the interior of the exhaust pipe 2, the rear end of the telescopic air pipe 3 passing through the middle part of the first circular sealing plate 201 and extending into the interior of the exhaust pipe 2, then passing through the middle part of the fixing ring 202, a sliding ring 301 fixedly connected to the outer wall of the telescopic air pipe 3 at the rear end of the first circular sealing plate 201 inside the exhaust pipe 2, and a spring 203 provided between the sliding ring 301 and the fixing ring 202 to allow the telescopic air pipe to... When the front end of the tube 3 is compressed, it can retract into the exhaust pipe 2. The front end of the telescopic air tube 3 is fixedly connected to a second circular sealing piece 302. The front end of the outer wall of the telescopic air tube 3 is provided with multiple air guide holes 303 in a ring array. When filling, the filling port of the plush toy is inserted into the front end of the filling tube 101. At this time, the front end of the telescopic air tube 3 is inserted into the inside of the plush toy. The front end of the telescopic air tube 3 pushes against the rear end of the inside of the plush toy, so that when the plush toy is inserted into the front end of the filling tube 101, the telescopic air tube 3 stretches the plush toy longitudinally, so that the plush toy is stretched longitudinally to facilitate the filling material to enter. When the plush toy is stretched, the telescopic air tube 3 retracts into the exhaust pipe 2 and simultaneously drives the slip ring 301 to compress the spring 203, so as to adjust the length of the front end of the telescopic air tube 3 extending out of the exhaust pipe 2, which is convenient for stretching plush toys of different sizes.

[0024] Please see Figure 2 and Figure 4After the plush toy's filling port is fixed to the filling tube 101, the filling machine fills the plush toy with down through the filling tube 101 via the filling table 1. During filling, the air inside the plush toy flows backward and enters the telescopic air tube 3 through multiple air guide holes 303 at the front end of the telescopic air tube 3, causing the air to flow backward through the telescopic air tube 3 and be discharged through the exhaust pipe 2.

[0025] Please see Figure 2 and Figure 3 The filling machine's filling platform 1 has side support plates 4 fixedly connected to both sides of the filling tube 101 at its upper end and at the middle front end. Hydraulic rods 401 are fixedly connected to the upper middle part of the outer sides of the two side support plates 4. C-shaped clamps 5 are connected to the upper middle part of the inner sides of the two side support plates 4. A thrust ring 102 is fixedly connected to the middle front end of the filling tube 101. The telescopic end of the hydraulic rods 401 on the side support plates 4 passes through the side support plates 4 and is fixedly connected to the middle outer side of the C-shaped clamps 5. The two hydraulic rods 401 synchronously drive the two C-shaped clamps 5 to clamp and fix the plush toy filling port on the filling tube 101. Simultaneously, the thrust ring 102 is located at the two C-shaped clamps. At the front end of the clamping plate 5, when the plush toy is put onto the filling tube 101, the thrust ring 102 opens the clamping position of the plush toy and engages with the two C-shaped clamping plates 5 to prevent the plush toy from detaching from the filling tube 101 during filling. Guide tubes 402 are fixedly connected to the outer end face of the side support plate 4 and to both ends of the hydraulic rod 401. Guide rods 501 are fixedly connected to both ends of the outer end face of the C-shaped clamping plate 5. The outer ends of the two guide rods 501 pass through the interior of the two guide tubes 402 and extend out of the outer end face of the side support plate 4. When the C-shaped clamping plate 5 moves, it is guided by sliding along the interior of the guide tubes 402 through the guide rods 501.

[0026] Working Principle: During use, the filling port of the plush toy is inserted into the front end of the filling tube 101. At this time, the second circular sealing plate 302 at the front end of the telescopic air tube 3 will press against the rear end of the toy, automatically stretching the longitudinal space of the toy during insertion. As the toy is inserted, the telescopic air tube 3 is compressed and retracts into the exhaust pipe 2, driving the slip ring 301 to compress the spring 203, thereby adaptively adjusting the extension length to accommodate toys of different sizes. After the toy is positioned, the hydraulic rods 401 on both sides simultaneously push the C-shaped clamp 5 to close, working with the thrust ring 102 to firmly clamp the filling port onto the filling tube 101. When filling begins, the filling material is injected into the toy through the filling tube 101. Simultaneously, internal air, under air pressure, enters the telescopic air tube 3 through the air guide hole 303 and is discharged along the exhaust pipe 2, effectively balancing the internal and external air pressure. The cooperation between the guide rod 501 and the guide tube 402 ensures stable clamping during the clamping process.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
