Description

Technical Field

[0001] The utility model relates to the technical field of down jacket production, in particular to a down filling nozzle of a down jacket filling machine. Background Art

[0002] In the production of down jackets, an important step is filling down, and this process requires the use of a down filling machine. The filling process of the down filling machine is to blow the down stored in it into the down jacket through a high-pressure fan. Specifically, the opening of the down jacket is put on the outside of the filling nozzle of the down filling machine, and the opening is closed on the filling nozzle to prevent the down from leaking out, and then the high-pressure fan is started to fill the down into the down jacket. In order to achieve the effect of windproof and warmth keeping, the air permeability of the fabric of the down jacket is generally poor, and the existing filling head is only a straight tube, which can only transport down and cannot return air. When filling, it is easy to cause the down jacket to inflate and expand, affecting the quality of the down filling. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a filling nozzle of a down jacket filling machine.

[0004] The technical solution of this utility model is as follows:

[0005] A filling nozzle of a down jacket filling machine comprises a filling tube, an outer sleeve of the filling tube is provided with an air return tube and a sliding plate, the sliding plate is located at the rear side of the air return tube, a filter plate is provided at the front end of the air return tube, a rear port is connected to the sliding plate through a soft rubber sleeve, and the filling tube, the filter plate, the air return tube, the soft rubber sleeve and the sliding plate jointly surround an air return cavity;

[0006] The sliding plate is provided with an air outlet hole connected to the air return cavity, and the front side of the sliding plate is rotatably connected with a cover plate, which covers the air outlet hole;

[0007] A limiting plate is fixed outside the filling tube and is located at the rear side of the sliding plate. A vent pipe is arranged on the limiting plate corresponding to the air outlet position. The vent pipe extends to the front side and can be inserted into the air outlet and lift the cover plate.

[0008] When in use, the worker puts the opening of the down jacket on the outside of the return air pipe, and as the filling nozzle is inserted, the opening of the down jacket is pressed against the sliding plate, and the sliding plate is pushed backward until it contacts the limit plate. At this time, the ventilation pipe is inserted into the air outlet to lift the cover plate, connecting the return air cavity with the outside world. When filling the down jacket, the gas filled in the down jacket enters the return air cavity through the filter plate, and then flows into the outside environment through the ventilation pipe, preventing the down jacket from expanding due to inflation.

[0009] In addition, after filling is completed, the sliding plate is moved back, the ventilation pipe exits the air outlet, and the cover plate is closed on the air outlet. As the sliding plate moves, the air in the return air cavity is discharged from the filter plate, and the down attached to the filter plate during filtration is blown off to avoid affecting the next use.

[0010] In the present application, the filter plate is preferably a truncated cone plate, so that the down jacket can be put on the outside of the return air pipe. The inner diameter of the filter plate is connected to the outside of the front end of the filling tube, and the outer diameter is connected to the front end of the return air pipe, so that the front end of the return air cavity is closed, so that air can only enter the return air cavity through the filter holes of the filter plate, thereby filtering the down and avoiding leakage of down.

[0011] In the present application, the sliding plate is a circular plate, the outer diameter of which is larger than the diameter of the return air pipe, so as to facilitate pushing the sliding plate.

[0012] In order to ensure that the gas flows out of the return air cavity in time, a plurality of air outlet holes are arranged around the filling tube on the sliding plate to avoid unequal filling volume and air outlet volume, which would result in poor return air effect.

[0013] In order to seal the return air chamber when the sliding plate moves forward so that the gas can only flow out through the filter plate, an elastic member is provided on the rotating shaft of the cover plate of the present application, and the cover plate covers the air outlet through the elastic force of the elastic member.

[0014] In the present application, a guide rail is protruded from the outer side of the filling tube along its axial direction, and a sliding groove matching the guide rail is provided at the edge of the sleeve interface of the sliding plate, so that the ventilation tube can be accurately inserted into the air outlet.

[0015] In order to facilitate the sliding plate to move forward, a spring is arranged between the sliding plate and the limit plate. When the sliding plate moves backward, the spring is compressed. When the filling is completed, the sliding plate can move forward under the action of the spring to complete the cleaning of the filter plate.

[0016] Preferably, the spring sleeve is arranged outside the filling tube so as to generate a uniform axial force on the sliding plate to facilitate smooth sliding.

[0017] In the present application, the soft rubber sleeve is provided with folding lines, and when the soft rubber sleeve is compressed, it folds along the folding lines. The folding lines not only standardize the contraction mode of the soft rubber sleeve, but also strengthen the three-dimensional shape of the soft rubber sleeve and improve the service life.

[0018] Furthermore, a connecting seat is provided at the rear end of the down filling tube, and the down filling nozzle is fixed on the down filling machine through the connecting seat.

[0019] The utility model provides a filling nozzle of a down jacket filling machine. By arranging an air return cavity, the gas injected into the down jacket can flow out through the air return cavity, thereby preventing the down jacket from expanding.

[0020] In addition, after the filling is completed, the sliding plate moves forward to blow the gas in the return air cavity out from the filter holes of the filter plate, thereby achieving the purpose of cleaning the filter plate and avoiding affecting the next use.

[0025] like Figure 1 As shown, an embodiment of the utility model provides a filling nozzle of a down jacket filling machine, which is used to discharge the air cylinder filled with down when filling down into the down jacket, so as to prevent the down jacket from expanding and leaking down.

[0026] The filling nozzle includes a filling tube 1, which is covered with a return air pipe 2 and a sliding plate 3. The sliding plate 3 is located at the rear side of the return air pipe 2. A filter plate 4 is provided at the front end of the return air pipe 2. The rear port is connected to the sliding plate 3 through a soft rubber sleeve 5. The filling tube 1, the filter plate 4, the return air pipe 2, the soft rubber sleeve 5 and the sliding plate 3 together surround a return air cavity 6.

[0027] When in use, the opening of the down jacket is put on the outer side of the return air pipe 2 and sealed, and the gas flushed into the down jacket enters the return air chamber 6 through the filter holes of the filter plate 4.

[0028] The sliding plate 3 is provided with an air outlet 31 connected to the return air chamber 6 for air outlet. The front side of the sliding plate 3 is rotatably connected with a cover plate 32, and an elastic member (not shown in the figure) is provided on the rotation axis of the cover plate 32. The cover plate 32 covers the air outlet 31 through the elastic force of the elastic member. A limit plate 7 is fixed to the outside of the filling tube 1 and is located at the rear side of the sliding plate 3. A vent pipe 71 is provided on the limit plate 7 corresponding to the position of the air outlet 31, and the vent pipe 71 extends to the front side.

[0029] In the initial state, the cover plate 32 covers the air outlet 31. When the sliding plate 3 moves backward and approaches the limit plate 7, the vent pipe 71 can be inserted into the air outlet 31 and lift the cover plate 32, so that the return air cavity 6 is connected with the outside, and the gas in the return air cavity 6 is discharged to the surrounding environment through the vent pipe 71, thereby achieving the purpose of discharging the gas filled in the down jacket and preventing the down jacket from expanding when filled.

[0030] When the filling is completed, the sliding plate 3 is moved forward, the ventilation pipe 71 withdraws from the air outlet 31, and the cover plate 32 covers the air outlet 31 under the elastic force of the elastic member, sealing the rear end of the return air chamber 6. Then, as the sliding plate 3 moves forward, the return air chamber 6 is compressed, so that the gas inside it is discharged from the filter holes of the filter plate 4, which is used to clean the filter plate 4 after the filling is completed to avoid the filter plate 4 being blocked and affecting the next use.

[0031] In order to ensure that the gas flows out of the return air chamber 6 in time, a plurality of air outlet holes 31 are evenly arranged on the sliding plate 3 along the circumference of the filling tube 1 to avoid unequal filling volume and air outlet volume, which would result in poor return air effect.

[0032] In addition, in order to quickly and accurately insert the vent pipe 71 into the air outlet 31, a guide rail 11 is protruded from the outer side of the filling tube 1. The guide rail 11 is in a long strip shape and extends axially along the filling tube 1. The edge of the sleeve of the sliding plate 3 is provided with a sliding groove (not shown in the figure) that cooperates with the guide rail 11. Through the cooperation of the guide rail 11 and the sliding groove, the sliding plate 3 can only move forward and backward, thereby facilitating the insertion of the vent pipe 71 into the air outlet 31.

[0033] Furthermore, in this embodiment, the filter plate 4 is preferably a truncated cone-shaped plate, so that the down jacket can be conveniently put on the outside of the return air pipe 2. The inner diameter of the filter plate 4 is fixedly connected to the outside of the front end of the filling tube 1, and the outer diameter is fixedly connected to the front end of the return air pipe 2, so that the front end of the return air cavity 6 is closed, so that the air can only enter the return air cavity 6 through the filter holes of the filter plate 4, thereby filtering the down and avoiding leakage of down.

[0034] In this embodiment, the sliding plate 3 is a circular plate, and its outer diameter is larger than the diameter of the return air pipe 2 to facilitate pushing the sliding plate 3 .

[0035] However, it should be understood that the sliding plate 3 can also be a plate of other shapes, such as a square plate, and this application is not limited thereto. However, regardless of the shape of the sliding plate 3, its outer edge size is preferably larger than the diameter of the return air pipe 2 to facilitate pushing the sliding plate 3 to move backward.

[0036] In this embodiment, a spring is provided between the sliding plate 3 and the limiting plate 7. The spring is compressed when the sliding plate 3 moves backward. When the filling is completed, the sliding plate 3 can move forward under the action of the spring to complete the cleaning of the filter plate 4, which is convenient to use.

[0037] Preferably, the spring sleeve is arranged outside the filling tube 1 so as to generate a uniform axial force on the sliding plate 3, so as to facilitate the sliding plate 3 to slide smoothly.

[0038] In this embodiment, the soft rubber sleeve 5 is provided with folding lines, and when the soft rubber sleeve 5 is compressed, it folds along the folding lines. The folding lines not only standardize the contraction mode of the soft rubber sleeve 5, but also can strengthen the three-dimensional shape of the soft rubber sleeve 5 and improve the service life.

[0039] In addition, a connecting seat 8 is provided at the rear end of the down filling tube 1 , and the down filling nozzle is fixed on the down filling machine through the connecting seat 8 .

[0040] When the filling nozzle of this embodiment is used, the worker puts the opening of the down jacket on the outside of the return air pipe 2. With the insertion of the filling nozzle, the opening of the down jacket is pressed against the sliding plate 3, and the sliding plate 3 is pushed backward until it is supported by the limit plate 7. At this time, the ventilation pipe 71 is inserted into the air outlet 31 and the cover plate 32 is lifted to connect the return air chamber 6 with the outside. When filling the down jacket, the gas filled in the down jacket enters the return air chamber 6 through the filter plate 4, and then flows into the outside environment through the ventilation pipe 71, thereby preventing the down jacket from being inflated.

[0041] After the filling is completed, the filling nozzle is withdrawn from the down jacket. During the withdrawal process, the sliding plate 3 is pushed forward by the spring, the ventilation pipe 71 withdraws from the air outlet 31, and the cover plate 32 covers the air outlet 31. As the sliding plate 3 moves, the air in the return air chamber 6 is discharged from the filter plate 4, and the down attached to the filter plate 4 during filtering is blown off to prevent the filter plate 4 from being blocked by the down and avoid affecting the next use.
