Description

Technical Field

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

[0002] Cotton-padded clothing refers to clothing filled with cotton or other insulating materials for warmth. It mainly consists of three parts: an outer layer (windproof fabric), an inner layer (insulating material), and filling (cotton or down). During the production of cotton-padded clothing, a down-filling machine is often used to facilitate the filling of the garment. In the prior art, patent publication number CN 109607466 B discloses a down-filling machine, including a main body with a pipe installed on one side and a down-filling port on the other. A box is installed at one end of the pipe, and a down inlet is embedded in the upper part of the box. A connecting circular plate is provided inside the box, with an elastic band around its ring. A connecting tube is embedded inside the connecting circular plate. While this method can fill cotton-padded clothing with down, the filling position and angle are fixed during the filling process, requiring workers to move the clothing to change the filling position, which can easily lead to uneven filling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a down filling machine for cotton clothing production. By using a telescopic tube with multiple positions and angles for down filling, the machine moves backward and rotates during the down filling process to change the down filling angle and position, making the down distribution inside the cotton clothing fabric more uniform, increasing the uniformity of down filling, and improving the quality of cotton clothing production. This can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a down filling machine for cotton garment production, comprising a frame, a down material box at the upper end of the frame, a support plate on the inner front wall of the frame, and a down filling mechanism;

The front end of the telescopic tube passes through the clearance sliding hole on the front surface of the frame. The screw is rotatably connected between the support plate and the inner wall of the front side of the frame. The screw is threadedly connected to the internally threaded tube on its outer arc surface. The internally threaded tube is connected to the telescopic tube in a transmission connection. The telescopic tube, which outputs down at multiple positions and angles, moves backward and rotates during the down filling process, changing the down filling angle and position, making the down material more evenly distributed inside the cotton clothing fabric, increasing the uniformity of down filling in the down filling machine, and improving the quality of cotton clothing production.

[0006] Furthermore, a microcontroller is provided on the front surface of the frame, and the input terminal of the microcontroller is electrically connected to an external power source to control the start and stop of the entire device.

The connecting frame is longitudinally slidably connected to the inside of the frame body. A rotating ring is rotatably connected in the rotating groove at the left end of the connecting frame. The rotating ring is set on the outer arc surface of the internally threaded tube. The telescopic tube is rotatably connected in the rotating groove at the right end of the connecting frame. Limiting rings are provided at both the front and rear ends of the outer arc surface of the telescopic tube. The rear plate of the connecting frame is located between the two limiting rings, so that the telescopic tube and the internally threaded tube move back and forth synchronously.

[0008] Furthermore, the filling mechanism also includes an outer toothed ring one and an outer toothed ring two. The outer toothed ring one is disposed on the outer arc surface of the telescopic tube, and the outer toothed ring two is disposed on the outer arc surface of the internally threaded tube.

[0010] Furthermore, the outer arc face of the telescopic tube is provided with a down filling oblique hole, and the down filling oblique hole is gradually inclined away from the axis of the telescopic tube from back to front. The left and right ends of the inner arc face of the telescopic tube are provided with guide oblique plates that cooperate with the down filling oblique holes to realize down output at multiple angles and positions.

[0011] Furthermore, guide columns are respectively provided between the vertical plate of the support plate and the inner wall of the front side of the frame. The guide columns are longitudinally slidably connected to the guide holes of the connecting frame to provide guiding support for the movement of the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This down filling machine for cotton-padded garment production has the following advantages:

[0013] By using a telescopic tube that dispenses down at multiple positions and angles, the down filling process is altered by moving backward and rotating. This changes the filling angle and position, making the down distribution within the cotton-padded fabric more uniform, increasing the uniformity of the down filling machine, and improving the quality of cotton-padded garment production.

The filling tube 31 is located in the middle of the vertical plate of the support plate 4. The inlet of the filling tube 31 is connected to the outlet pipe of the filling box 2. The telescopic tube 32 is movably sleeved on the outer arc surface of the filling tube 31. A sealing rubber ring is provided at the rear end of the inner arc surface of the telescopic tube 32. The sealing rubber ring fits against the outer arc surface of the filling tube 31 to seal the telescopic tube 32 and the filling tube 31.

The screw 33 is rotatably connected between the vertical plate of the support plate 4 and the inner wall of the front side of the frame 1. The screw 33 is threadedly connected to the internally threaded tube 34 on the outer arc surface of the screw 33. The internally threaded tube 34 is connected to the telescopic tube 32 in a transmission connection. The filling mechanism 3 also includes a connecting frame 35 and a rotating ring. 36 and limiting ring 37, the connecting frame 35 is longitudinally slidably connected to the inside of the frame 1, the rotating ring 36 is rotatably connected in the rotating groove at the left end of the connecting frame 35, the rotating ring 36 is set on the outer arc surface of the internal threaded tube 34, the telescopic tube 32 is rotatably connected in the rotating groove at the right end of the connecting frame 35, the front and rear ends of the outer arc surface of the telescopic tube 32 are provided with limiting rings 37, the rear plate of the connecting frame 35 is located between the two limiting rings 37, the rear side of the connecting frame 35 is provided with corrugated tubes between the vertical plate of the support plate 4 and between the front surface of the connecting frame 35 and the front inner wall of the frame 1, the corrugated tubes are movably sleeved on the outer arc surface of the screw 33, the corrugated tubes extend and retract during the movement of the connecting frame 35, and always provide protection for the screw 33, the filling mechanism 3 also includes an external toothed ring 38 and an external toothed ring 39, the external toothed ring 38 The external gear ring 39 is located on the outer arc surface of the telescopic tube 32 and on the outer arc surface of the internal threaded tube 34. The external gear ring 39 meshes with the external gear ring 38. A motor 5 is located on the surface of the front plate of the connecting frame 35. A gear 6 is located at the end of the output shaft of the motor 5. The gear 6 meshes with the external gear ring 39. The input end of the motor 5 is electrically connected to the output end of the microcontroller 9. When the motor 5 is started, the output shaft of the motor 5 drives the gear 6 to rotate. Through the meshing connection between the gear 6 and the external gear ring 39, the external gear ring 39 drives the internal threaded tube 34 and the rotating ring 36 to rotate. Through the meshing connection between the external gear ring 38 and the external gear ring 39, the external gear ring 38 drives the telescopic tube 32 to rotate. The rotating ring 36 and the telescopic tube 32 both rotate relative to the connecting frame 35. The threaded connection between screw 34 and bolt 33 allows the threaded tube 34 to move backward during rotation, pushing the connecting frame 35 and telescopic tube 32 to move backward synchronously. This allows the telescopic tube 32 to move backward during rotation, adjusting the filling angle and position within the cotton-padded fabric. A reflective laser rangefinder sensor is installed on the inner front wall of the frame 1 to detect the distance between the connecting frame 35 and the inner front wall of the frame 1, facilitating control of the extension length of the telescopic tube 32. During use, the initial position of the telescopic tube 32 is controlled according to the required filling depth of the cotton-padded garment. During filling, the operator simply presses the cotton-padded garment against the front surface of the frame 1, allowing the telescopic tube 32 to insert to the specified depth. Throughout the filling process, the operator maintains pressure on the cotton-padded garment to keep its position fixed.The outer arc face of the telescopic tube 32 is provided with down-filling inclined holes 7. These holes 7 gradually slope away from the axis of the telescopic tube 32 from back to front. Guide inclined plates 8, which mate with the down-filling inclined holes 7, are provided at both ends of the inner arc face of the telescopic tube 32. During the down-filling process, some down is discharged directly from the inclined opening at the front end of the telescopic tube 32, while some down is discharged from the down-filling inclined holes 7 under the guidance of the guide inclined plates 8, achieving multi-position, multi-angle down filling. Guide posts 10 are provided between the vertical plate of the support plate 4 and the inner front wall of the frame 1. The guide posts 10 are longitudinally slidably connected to the guide holes of the connecting frame 35, providing guiding support for the movement of the connecting frame 35.

[0024] The working principle of the down filling machine for cotton-padded garment production provided by this utility model is as follows: During the cotton-padded garment production process, when it is necessary to fill the cotton-padded garment with down, the cotton-padded garment fabric is placed on the outer arc surface of the telescopic tube 32, so that the front end of the telescopic tube 32 penetrates deep into the interior of the cotton-padded garment. Then, the air compressor at the lower end of the frame 1 is started by the microcontroller 9. The compressed air generated by the air compressor enters the down filling box 2 through the compressed air pipe at the upper end of the down filling box 2. Due to the sealed opening at the upper end of the down filling box 2, the compressed air carries the down in the down filling box 2 into the filling tube 31 and fills the interior of the cotton-padded garment fabric along the telescopic tube 32, thus achieving down filling. During the down filling process, some down is directly discharged from the inclined opening at the front end of the telescopic tube 32, and some down is guided by the guide plate 8 and flows out from the down filling inclined hole 7. The filling process involves multiple positions and angles of down filling, while simultaneously starting motor 5. The output shaft of motor 5 drives gear 6 to rotate. Through the meshing connection between gear 6 and external gear ring 39, external gear ring 39 drives internal threaded tube 34 and rotating ring 36 to rotate. Through the meshing connection between external gear ring 38 and external gear ring 39, external gear ring 38 drives telescopic tube 32 to rotate. Both rotating ring 36 and telescopic tube 32 rotate relative to connecting frame 35. Through the threaded connection between threaded tube 34 and screw 33, threaded tube 34 moves backward during rotation, pushing connecting frame 35 and telescopic tube 32 to move backward synchronously. This allows telescopic tube 32 to move backward during rotation, adjusting the filling angle and position within the cotton fabric for more uniform down filling.

[0025] It is worth noting that the microcontroller 9 disclosed in the above embodiments can be an AT89C4051 microcontroller, and the motor 5 can be freely configured according to the actual application scenario. The motor 5 can be a 42BYHJ01 stepper motor, and the microcontroller 9 controls the operation of the motor 5 using methods commonly used in the prior art.
