Description

Technical Field

[0001] The utility model relates to the technical field of down jackets, in particular to a device for filling and sealing down jackets. Background Art

[0002] A down jacket is a top filled with down, with a large and round shape. Down jackets generally contain more than half duck down, and some small feathers can be mixed in. The duck down is cleaned, sterilized at high temperature, and then filled into clothes to make a down jacket. Down jackets have good warmth retention and are mostly worn by people in cold areas. They are also commonly used by polar expedition personnel.

[0003] The Chinese patent with authorization announcement number CN211984023U discloses a device for filling and sealing down jackets, including a base plate, the upper surface of which is fixedly connected to a processing table through a number of support columns, and the upper surface of the processing table is fixedly connected to a beam frame. When the device for filling and sealing down jackets is in use, the position of the down jacket to be sealed is placed on the support block, and the inverted U-shaped pressure rod is pushed downward by an electric push rod to press the position of the down jacket to be sealed onto the support block, and then the motor and the exhaust fan are started. The rotation of the motor drives the rotation of the screw rod, and the rotation of the screw rod drives the horizontal movement of the slider, thereby driving the horizontal movement of the blow pipe, so that the exhaust fan can blow the down into the down jacket, and then a sewing machine (or other suitable tools) is used to sew the position to be sealed, so that no manual operation is required during the sealing process, which reduces the labor intensity of workers and improves the processing efficiency of filling and sealing down jackets.

[0004] However, when the above solution is used to seal the filling sealing part of the down jacket, the wrinkles and unevenness at the sealing part lead to uneven sewing. The uneven fabric causes wrinkles at the sealing part during sealing, which affects the appearance and quality. In addition, the position of the down jacket needs to be manually adjusted to complete the sealing, which increases the operation time and reduces the overall production efficiency. Therefore, a device for filling and sealing down jackets is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The moving block 21 is slidably connected to the frame 1 to limit its position so as to provide a stable moving trajectory.

[0032] When the cam 31 is in the unlocked position, the cam 31 is unlocked and the cam 31 is unlocked, so that the cam 31 can be unlocked and the cam 31 can be unlocked.

[0033] In order to enable the smoothing roller 4 to rotate freely, the outer surface of the support plate 31 is slidingly connected to the outer surface of the limit plate 33, and the outer surface of the support plate 31 is rotatably connected to the inner wall of the groove of the smoothing roller 4. The outer surface of the support plate 31 is rotatably connected to the roller 41, and the outer surface of the roller 41 is in rolling contact with the inner wall of the groove of the L-shaped groove 34. The support plate 31 is slidingly connected to the limit plate 33, which fixes it without affecting its movement. The rotational connection between the support plate 31 and the smoothing roller 4 enables the smoothing roller 4 to rotate freely, thereby effectively performing the task of smoothing the cloth. The rolling contact between the roller 41 rotatably connected to the support plate 31 and the inner wall of the groove of the L-shaped groove 34 reduces friction while improving the smoothness of movement.

[0034] By setting a smoothing mechanism, the filling seal of the down jacket is smoothed, the piston rod of the hydraulic cylinder 2 is extended and retracted to drive the moving block 21 to move, the moving block 21 is slidably connected to the frame 1, and its position is limited. The support plate 31 is slidably connected to the sliding block 3, so that the support plate 31 can be raised and lowered on the sliding block 3. The support plate 31 is rotatably connected to the connecting rod 32, and the connecting rod 32 is rotatably connected to the moving block 21. The movement of the moving block 21 drives the support plate 31 to move through the connecting rod 32, thereby driving the sliding block 3 to move on the slidingly connected frame 1, and the outer surface of the limiting plate 33 is provided with an L-shaped groove 34 , in order to provide a moving track for the roller 41, the support plate 31 is slidably connected to the limit plate 33, and the rotational connection between the support plate 31 and the smoothing roller 4 enables the smoothing roller 4 to rotate freely. The roller 41 rotatably connected on the support plate 31 is in rolling contact with the inner wall of the groove of the L-shaped groove 34, reducing friction, thereby achieving the effect of smoothing the filling seal of the down jacket, thereby solving the technical problems that when the filling seal of the down jacket is sealed, the wrinkles and unevenness at the seal lead to uneven sewing, and the uneven fabric causes wrinkles at the seal when sealing, affecting the appearance and quality.

[0035] In order to seal the filling sealing part of the down jacket, a sealing mechanism is provided on the outer surface of the frame 1. The sealing mechanism includes a laser machine housing 71. The movement of the laser machine housing 71 seals the filling sealing part of the down jacket.

[0036] In order to drive the driving bevel gear 51 to rotate, the sealing mechanism also includes a motor 5, which is fixedly mounted on the outer surface of the frame 1, and the output shaft of the motor 5 is slidably sleeved with the driving bevel gear 51 and the driving gear 52, respectively. The outer surface of the driving bevel gear 51 is fixedly mounted to the outer surface of the driving gear 52, and an electromagnet 53 is fixedly mounted on the outer surface of the frame 1. The outer surface of the electromagnet 53 is magnetically connected to the outer surface of the driving bevel gear 51 through an adsorption member, and a spring 54 is fixedly mounted on the outer surface of the frame 1 to force the driving gear 52 to reset. The motor 5 is fixedly mounted on the frame 1 and fixed to it. A key is fixedly welded on the output shaft of the motor 5 to engage with the inner wall of the driving bevel gear 51 and the driving gear 52. The key slots are slidably connected, and the rotation of the output shaft of the motor 5 drives the driving bevel gear 51 and the driving gear 52 to rotate through the cooperation of the key and the key slot. The driving bevel gear 51 and the driving gear 52 are fixedly installed so that they can move synchronously. The wire of the electromagnet 53 is connected to the power supply equipment to energize the electromagnet 53, and the driving bevel gear 51 and the driving gear 52 move. The driving bevel gear 51 is meshed with the rotating bevel gear 62, and the electromagnet 53 is de-energized. One end of the spring 54 fixedly installed on the frame 1 is fixed to the driving gear 52, so that the driving gear 52 is reset and meshed with the rotating gear 72, synchronously driving the driving bevel gear 51 to reset and disengage from the rotating bevel gear 62, so as to improve the precise adjustment function.

[0037] In order to drive the rotating screw 6 to rotate, the outer surface of the frame 1 is rotatably connected to the rotating screw 6 through a bearing, and the outer surface of the rotating screw 6 is threadedly connected to a pressure block 61. The outer surface of the pressure block 61 is slidingly connected to the outer surface of the frame 1, and a rotating bevel gear 62 is fixedly installed on the outer surface of the rotating screw 6. After the driving bevel gear 51 moves, it engages with the rotating bevel gear 62 and is rotationally connected to the rotating screw 6 through the frame 1, fixing it without affecting its rotation. When the electromagnet 53 is energized, the driving bevel gear 51 engages with the rotating bevel gear 62, driving the rotating screw 6 to rotate, driving the pressure block 61 threadedly connected to it to rise and fall on the slidingly connected frame 1, so as to press the down jacket.

[0038] In order to drive the movable screw 7 to rotate, the outer surface of the frame 1 is rotatably connected to the movable screw 7 through a bearing. The outer surface of the movable screw 7 is threadedly connected to the inner wall of the groove of the laser machine housing 71. The outer surface of the laser machine housing 71 is slidingly connected to the inner wall of the groove of the frame 1. The outer surface of the movable screw 7 is fixedly installed with a rotating gear 72. After the driving gear 52 is reset, it engages with the rotating gear 72. The frame 1 is rotatably connected to the movable screw 7 through the bearing, which fixes it without affecting its rotation. The electromagnet 53 is powered off, and the driving gear 52 is reset to engage with the rotating gear 72, driving the movable screw 7 to rotate and driving the laser machine housing 71 to rotate and move. However, since the square groove opened on the frame 1 is slidably connected to the laser machine housing 71, the laser machine housing 71 is limited so that it can only move, so as to seal the filling sealing part of the down jacket.

[0039] By setting up a sealing mechanism, the filling sealing part of the down jacket is sealed, and the motor 5 drives the driving bevel gear 51 and the driving gear 52 to rotate. The driving bevel gear 51 and the driving gear 52 are fixedly installed so that they can move synchronously. The electromagnet 53 is energized, and the driving bevel gear 51 and the driving gear 52 move. The driving bevel gear 51 is engaged with the rotating bevel gear 62, driving the rotating screw 6 to rotate, driving the pressing block 61 threadedly connected thereto to rise and fall on the slidingly connected frame 1 to press the down jacket. The electromagnet 53 is powered off, and the driving gear 52 is reset to engage with the rotating gear 72, driving the moving screw 7 to rotate, so that the laser machine housing 71 threadedly connected thereto moves on the slidingly connected frame 1 to seal the filling sealing part of the down jacket. This solves the technical problem that when sealing the filling sealing part of the down jacket, the position of the down jacket needs to be manually adjusted to complete the sealing, which increases the operation time and reduces the overall production efficiency.

[0040] Working principle: When it is necessary to press the down jacket, the driving motor 5 drives the driving bevel gear 51 and the driving gear 52 to rotate. At the same time, the staff connects the wire of the electromagnet 53 fixed on the frame to the power supply equipment, so that the electromagnet 53 is energized, and the driving bevel gear 51 moves to engage with the rotating bevel gear 62, driving the rotating screw 6 to rotate, driving the pressing block 61 threadedly connected to it to descend on the slidingly connected frame 1, thereby pressing the down jacket;

[0041] When it is necessary to smooth the filling and sealing portion of the down jacket, the motor 5 is turned off and the hydraulic cylinder 2 is started. The extension and retraction of the piston rod of the hydraulic cylinder 2 drives the moving block 21 fixed thereto to move on the slidingly connected frame 1. Since the connecting rod 32 is rotatably connected to the moving block 21 and the supporting plate 31 respectively, the movement of the moving block 21 can drive the supporting plate 31 to move on the slidingly connected limiting plate 33 through the connecting rod 32, and synchronously drives the sliding block 3 to move on the slidingly connected frame 1. The roller 41 rotatably connected on the supporting plate 31 rolls in contact with the L-shaped groove 34 provided on the limiting plate 33, reducing friction while improving a movement trajectory for it. The supporting plate 31 is then driven to move by the sliding block 3 after it descends on the sliding block 3 in sliding connection, thereby causing the smoothing roller 4 rotatably connected to the support block to descend, contact the down jacket, and move to smooth it.

[0042] After smoothing is completed, the hydraulic cylinder 2 is closed, the motor 5 is started, the electromagnet 53 is powered off, and the spring 54 resets the driving gear 52 to engage with the rotating gear 72, synchronously driving the driving bevel gear 51 to reset and disengage from the rotating bevel gear 62. The rotating gear 72 drives the moving screw 7 to rotate, so that the laser machine housing 71 threadedly connected to it moves on the slidingly connected frame 1 to seal the filling sealing part of the down jacket.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
