Description

Technical Field

[0001] This utility model relates to the field of down jacket production technology, specifically to a down filling machine for down jackets. Background Technology

[0002] The down filling process in down jacket production mainly relies on manual labor. After the down is weighed in a fixed quantity, it is filled into the down jacket using a down filling machine. However, existing down filling machines have fixed-size filling tubes, which makes it difficult to insert the tubes into smaller down jackets, affecting the filling effect and making them inconvenient to use. The filling tubes in these machines are generally hollow tubes, which are directly inserted into the garment during filling. This increases the amount of air inside the garment during filling, and if the garment material has poor breathability, it is prone to tearing.

[0003] Patent document CN219515400U discloses a down filling machine for down garments. Through the setting of alignment holes, filling tubes A, B, and C, the machine selects filling tubes A, B, and C based on the size of the down filling opening of the garment. After selecting filling tube A, the slot cover is installed inside the mounting slots on both sides of filling tube A. Bolts are used to connect the slot cover to the upper plate. At this point, rotating the movable block aligns the selected filling tube A with the alignment hole, allowing the operator to... The down filling port is fitted onto the outer surface of the down filling tube A, facilitating tube selection and ease of use. Through the design of a tension spring, sealing layer, and abrasion-resistant layer, during filling, pressing the groove cover by hand causes the upper plate to be pushed into the limiting groove by the groove cover. The tension spring extends, and the rubber layer pulls the sealing layer tightly against the inside of the inner groove. The sealing layer is located on both sides of the alignment hole, sealing the alignment hole and the down filling tube A. Starting the down filling machine initiates filling. The abrasion-resistant layer protects the rubber layer. However, this technical solution requires rotating the movable block when using down filling tubes of different sizes. When the filling area of ​​the down jacket varies in size, frequent rotation of the movable block is necessary, reducing filling efficiency. This technical solution also fails to address the problem of down being easily bursted when air increases inside the down jacket.

[0004] Patent document CN202112381U discloses a down filling mechanism for a fully automatic down filling machine. A fixed quantity of down from the metering mechanism's hopper is amplified and enters a filling tube. The end of the filling tube is inserted into the garment, bedding, or similar item being filled. Simultaneously, airflow enters a return channel through a return air hole. This return channel connects to a collection branch pipe, which collects dust and down through a breathable dust collection bag fitted onto the collection branch pipe. This technical solution effectively solves the problem of down bursting due to increased air volume by expelling air from inside the down jacket during the filling process. However, the filling tube in this solution is not suitable for down filling openings of different sizes on down jackets. Utility Model Content

[0005] The main objective of this invention is to provide a down filling machine that can be used with down filling openings of different sizes on down jackets during the down filling process. This down filling machine can remove air from inside the down jacket during operation, thus preventing the down from bursting due to increased air inside the jacket.

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

[0007] A down filling machine for down garments includes a machine body. A fixed sleeve is fixedly connected to the down outlet of the machine body. Multiple down filling components are fixedly connected to the fixed sleeve. The multiple down filling components have the same structure but different diameters. Each down filling component includes a fixed tube fixedly connected to the fixed sleeve. A sleeve is rotatably and sealingly fitted on the outside of the fixed tube. An inner hole is opened at the end of the fixed tube away from the fixed sleeve, and an outer hole is opened at the end of the sleeve away from the fixed sleeve. The outer hole and the inner hole are offset. After the sleeve rotates, the outer hole and the inner hole communicate. An air hole is opened on the side wall of the sleeve, penetrating the side wall of the sleeve. A collar is fixedly fitted on the fixed tube. An annular cavity is opened inside the collar. The end of the sleeve near the fixed sleeve is rotatably and sealingly connected to the collar. An arc-shaped groove is opened on the side of the collar facing the sleeve, communicating with the annular cavity. The end of the sleeve near the collar blocks the arc-shaped groove. After the sleeve rotates, the air hole communicates with the arc-shaped groove. A flexible tube is fixed on the collar, communicating with the annular cavity and a collection box.

[0008] Specifically, the outlet ends of the plurality of down filling components are far apart from each other.

[0009] Specifically, a baffle is fixed inside the end of the fixed tube away from the fixed sleeve, and the inner hole is opened on the baffle.

[0010] Specifically, there are two inner holes, which are symmetrically arranged according to the axis of the fixed tube, and there are two outer holes, which are symmetrically arranged according to the axis of the sleeve.

[0011] Specifically, the outer wall of the fixed tube and the inner wall of the sleeve are connected by a rotating sealing ring.

[0012] Specifically, an annular groove is formed on the inner wall of the sleeve, and a convex ring is fixed on the outside of the fixed tube, with the convex ring rotatably disposed in the annular groove.

[0013] Specifically, two arc-shaped plates are fixed on the end of the sleeve away from the fixed sleeve, and two external holes are located between the two arc-shaped plates, with the ends of the two arc-shaped plates away from the sleeve approaching each other.

[0014] Specifically, the diameter of the end of the arc-shaped plate furthest from the sleeve is smaller than the diameter of the end of the arc-shaped plate closest to the sleeve.

[0015] Specifically, the collection box has an outlet hole, and a filter screen is fixed inside the outlet hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting multiple down filling components with different diameters but the same structure, users can flexibly select the appropriate component according to the size of the down filling port of the down jacket, avoiding down leakage or down filling difficulties caused by size mismatch, thus enhancing the versatility and ease of operation of the equipment.

[0018] 2. During the down filling process, the air inside the down jacket is discharged into the collection box through the air holes, arc grooves and annular cavity system, and the pressure is released through the outlet to prevent the pressure inside the collection box from rising; at the same time, the filter effectively intercepts the down discharged with the air, which is convenient for recycling and reuse and reduces down loss.

[0019] 3. An arc-shaped plate is added to the end of the sleeve, which can change the direction of movement of down and air and reduce their speed, thereby reducing the impact on the down jacket and effectively avoiding the problem of down jacket being damaged due to excessive airflow during filling (especially effective when applied to semi-automatic down filling machines).

[0020] 4. The sleeve rotation design allows the inner and outer holes to connect and the air vents to connect with the arc-shaped groove after the sleeve rotates, simplifying the down filling start-up process. At the same time, the guiding effect of the arc plate makes it easy for the sleeve to be quickly and accurately inserted into the down filling port of the down jacket, improving the overall operating efficiency.

[0029] 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.

[0030] Example 1: Refer to Figures 1-7 As shown, a down filling machine for down garments includes a down filling machine body 1. A fixed sleeve 2 is fixedly connected to the down outlet of the down filling machine body 1. A plurality of down filling components 3 are fixedly connected to the fixed sleeve 2. The plurality of down filling components 3 have the same structure, different diameters, and their outlet ends are far apart from each other.

[0031] The down filling assembly 3 includes a fixed tube 31 that is fixedly connected to the fixed sleeve 2, and a sleeve 32 is rotatably and sealingly fitted on the outside of the fixed tube 31. Specifically, the outer wall of the fixed tube 31 and the inner wall of the sleeve 32 are rotatably and sealingly connected by a sealing ring. An annular groove is formed on the inner wall of the sleeve 32, and a protruding ring 4 is fixed on the outside of the fixed tube 31, and the protruding ring 4 is rotatably disposed in the annular groove.

[0032] The fixed tube 31 has an inner hole 37 at the end away from the fixed sleeve 2. Specifically, a baffle 36 is fixed inside the fixed tube 31 at the end away from the fixed sleeve 2, and the inner hole 37 is formed on the baffle 36. The sleeve 32 has an outer hole 38 at the end away from the fixed sleeve 2. The outer hole 38 and the inner hole 37 are offset, and the outer hole 38 and the inner hole 37 communicate after the sleeve 32 is rotated.

[0033] There are two inner holes 37, which are symmetrically arranged about the axis of the fixed tube 31. There are two outer holes 38, which are symmetrically arranged about the axis of the sleeve 32.

[0034] A vent 39 is provided on the side wall of the sleeve 32, and the vent 39 penetrates the side wall of the sleeve 32. A collar 33 is fixedly fitted on the fixed tube 31, and an annular cavity is provided inside the collar 33. The end of the sleeve 32 near the fixed sleeve 2 is rotatably and sealingly connected to the collar 33. An arc-shaped groove 331 is provided on the side of the collar 33 facing the sleeve 32, and the arc-shaped groove 331 communicates with the annular cavity. The end of the sleeve 32 near the collar 33 blocks the arc-shaped groove 331. After the sleeve 32 is rotated, the vent 39 communicates with the arc-shaped groove 331.

[0035] A flexible hose 34 is fixed to the collar 33, and the flexible hose 34 connects the annular cavity and the collection box. The collection box has an outlet hole, and a filter screen is fixed inside the outlet hole.

[0036] In this embodiment, since the multiple down filling components 3 have the same structure, different diameters, and far apart from each other, the appropriate diameter of the down filling component 3 can be selected according to the size of the down filling opening on the down jacket.

[0037] During the filling process, the sleeve 32 of the selected filling component 3 is inserted into the filling port of the down jacket, the filling machine body 1 is started, and then the sleeve 32 is rotated. After the sleeve 32 is rotated, the inner hole 37 and the outer hole 38 are connected, and the air hole 39 is connected to the arc groove 331. The down in the filling machine body 1 enters the down jacket along with the air through the down outlet, the fixing sleeve 2, the fixing tube 31, the inner hole 37 and the outer hole 38.

[0038] Air from inside the down jacket enters the annular cavity through the air vent 39 and the arc-shaped groove 331, and then flows into the collection box through the hose 34. Because the collection box has an outlet, the air inside can escape through the outlet, preventing pressure buildup. During the air expulsion process, some down feathers are also expelled and enter the collection box. A filter screen is fixed inside the outlet of the collection box to trap the down feathers, facilitating their collection.

[0039] Example 2: Based on Example 1, referring to... Figure 2 , Figure 3 and Figure 6 As shown, two arc-shaped plates 35 are fixed on the end of the sleeve 32 away from the fixed sleeve 2. Two external holes 38 are located between the two arc-shaped plates 35, and the ends of the two arc-shaped plates 35 away from the sleeve 32 are close to each other. The diameter of the end of the arc-shaped plate 35 away from the sleeve 32 is smaller than the diameter of the end of the arc-shaped plate 35 close to the sleeve 32.

[0040] By setting the arc-shaped plate 35, during the process of down and air being discharged from the outer hole 38 and entering the down jacket, the movement direction of the down and air can be changed by the obstruction of the arc-shaped plate 35, and the movement speed of the down and air can be reduced, thus avoiding a large impact on the down jacket during filling and preventing damage to the down jacket. When the technical solution of this embodiment is applied to a semi-automatic down filling machine, it can effectively avoid the problem of down jackets being blown apart due to uncontrollable airflow.

[0041] The two arc-shaped plates 35 are designed to guide the sleeve 32, making it easier for the sleeve 32 to pass through the down filling port of the down jacket, thereby further improving the down filling efficiency.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
