Description

Technical Field

[0001] This invention relates to the field of down jacket production and processing technology, and in particular to a down leakage detection device used in down jacket production. Background Technology

[0002] Consumer upgrading has driven consumers to demand higher quality down jackets, with particular attention to the issue of down leakage. Down leakage detection devices have become key equipment for quality control in production. By simulating scenarios such as friction and compression during wear, they can detect the risk of down leakage in fabrics, seams, or filling processes in advance, reducing the probability of substandard products entering the market. However, existing detection devices have shortcomings. First, the simulation effect of friction and knocking is not good, and it is difficult to reproduce the complex stress of actual wear. Second, the down leakage is not completely collected, and fine down fibers are easily left behind, thus affecting the accuracy of the test. Summary of the Invention

[0003] The main objective of this invention is to provide a down leakage detection device for down jacket production, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A down leakage detection device for down jacket production includes a base platform. Load-bearing support legs are fixedly connected to the lower perimeter of the base platform. An equipment mounting platform is fixedly connected to the upper end of the base platform. A rotating rectangular opening is formed on the upper left side of the equipment mounting platform. A control panel is fixedly connected to the upper right side of the equipment mounting platform. A parameter display screen is provided at the upper rear of the control panel. A down jacket detection rotating device is fixedly connected to the upper left side of the equipment mounting platform. The right side of the down jacket detection rotating device is located within the rotating rectangular opening. A bottom elastic friction impact component is provided in the lower part of the down jacket detection rotating device. A top adjustable impact structure is fixedly connected to the upper middle part of the down jacket detection rotating device. A down leakage adsorption and collection structure is fixedly connected to the upper left side of the down jacket detection rotating device.

[0006] Preferably, the down jacket detection rotating device includes a rotating driver. The output end of the rotating driver passes through the upper left end of the equipment mounting platform and is fixedly connected to a transparent detection rotating box. The right end of the transparent detection rotating box is movably connected to the equipment mounting platform via a bearing. A visible sealing door is movably installed on the left front end of the transparent detection rotating box. A door latch is movably installed on the middle right end of the visible sealing door. A door lock fastening bolt is threadedly connected to the front right end of the transparent detection rotating box. The door lock fastening bolt is threadedly connected to the door latch. Four fixing screws are threadedly connected to the middle of the inner left and inner right walls of the transparent detection rotating box. Down jacket clamping and fixing structures are threadedly connected to the inner wall of the transparent detection rotating box via four fixing screws. Two down jacket clamping and fixing structures are provided.

[0007] By adopting the above technical solution: driving the rotating box to rotate, providing a closed testing space, facilitating the observation and fixation of down jackets, dynamic testing simulation can be realized, sealed observation is convenient, and the stable clamping ensures testing stability, laying the foundation for subsequent friction and impact testing.

[0008] Preferably, the down jacket clamping and fixing structure includes a clamping and mounting frame. The clamping and mounting frame has screw mounting holes that pass through to the left and right around its left end. A bidirectional clamping component is fixedly connected to the upper end of the clamping and mounting frame. The lower part of the bidirectional clamping component is located inside the clamping and mounting frame. A clamping limiting port that passes through to the left and right is opened in the middle of the left end of the clamping and mounting frame.

[0009] By adopting the above technical solution: the clamping components are installed through a frame, and the bidirectional clamping assembly provides clamping power, resulting in a compact structure that provides stable support for the clamping function. The detachable design facilitates maintenance and adapts to the clamping needs of down jackets of different sizes.

[0010] Preferably, the two down jacket clamping and fixing structures are distributed in a left-right mirror image, and the clamping and mounting frame is detachably connected to the transparent detection rotating box through four screw mounting holes and four fixing screws.

[0011] By adopting the above technical solution, the two down jacket clamping and fixing structures are distributed in a mirror image to achieve a symmetrical and detachable connection, which not only ensures symmetrical clamping force, but also facilitates installation and disassembly, thereby improving the flexibility of the device.

[0012] Preferably, the bidirectional clamping assembly includes a drive motor. The output end of the drive motor passes through the upper middle part of the clamping mounting frame and is fixedly connected to a bidirectional threaded rod. The lower end of the bidirectional threaded rod is movably connected to the clamping mounting frame via a bearing. Movable fixing blocks are threadedly connected to the upper and lower parts of the outer surface of the bidirectional threaded rod. A clamping limiting block is fixedly connected to one end of each of the two movable fixing blocks near the clamping limiting port. A clothing clamping pliers head is fixedly connected to one end of each of the two clamping limiting blocks. An auxiliary fixing magnetic block and a damage-prevention clamping pad are fixedly connected sequentially from left to right to the ends of the two clothing clamping pliers that are close to each other.

[0013] By adopting the above technical solution: the motor drives the threaded rod to move the clamp head in both directions, realizing the automated clamping of down jackets. The clamping force is adjustable, the anti-damage pad protects the fabric, and the magnetic block enhances the fixation, thereby improving the clamping stability and ease of operation.

[0014] Preferably, the two bidirectional clamping components are arranged in a left-right mirror image distribution, and the two longitudinally distributed clamping limiting blocks are movably connected to the clamping limiting port.

[0015] By adopting the above technical solution: the bidirectional clamping components are distributed in a mirror image to ensure clamping symmetry, limit the direction of movement of the clamping head, avoid clamping deviation, ensure that the down jacket is subjected to uniform force, improve detection consistency, and prevent the clamping components from shaking and affecting detection accuracy.

[0016] Preferably, the bottom elastic friction impact component includes a bottom mounting plate, which is fixedly connected to the inner lower wall of the transparent detection rotating box. Nine elastic support springs are fixedly connected to the upper end of the bottom mounting plate. Bottom friction rubber heads are fixedly connected to the ends of the nine elastic support springs away from the bottom mounting plate. The nine bottom friction rubber heads are distributed in a rectangular array. Several friction protrusions are fixedly connected to the outer surface of each of the nine bottom friction rubber heads. The nine bottom friction rubber heads are in contact with the bottom fabric of the down jacket.

[0017] By adopting the above technical solution: the rubber head is driven by the elasticity of the spring to rub and strike the bottom of the down jacket, simulating the friction and compression in real wear. The raised particles enhance the friction effect, and the elastic design avoids damage to the fabric, thus improving the authenticity of the test.

[0018] Preferably, the top adjustable impact structure includes a cylinder, the output end of which passes through the upper middle part of the transparent detection rotating box and is fixedly connected to a mounting base. Nine connecting rods are fixedly connected at equal intervals at the lower end of the mounting base. Each of the nine connecting rods has a top impact rubber head fixedly connected to its end away from the mounting base. All nine top impact rubber heads make contact with the upper fabric of the down jacket.

[0019] By adopting the above technical solution, the cylinder drives the rubber head to impact the upper part of the down jacket up and down. The impact force can be adjusted by the cylinder, and the multi-point impact covers the entire area, simulating external forces in multiple directions, effectively detecting the risk of down leakage from the fabric and seams.

[0020] Preferably, the lint adsorption and collection structure includes a collection box fixing frame, a lint collection transparent box, and a miniature negative pressure fan. The lower end of the collection box fixing frame is fixedly connected to the upper left part of the transparent detection rotating box. A collection box placement slot is opened at the left end of the collection box fixing frame. A fixing bolt is threadedly connected to the upper right end of the collection box fixing frame. The lint collection transparent box is snapped into the collection box placement slot. A through lint inlet hole is opened in the middle of the end of the lint collection transparent box that is in close contact with the collection box fixing frame. A through fixing bolt hole is opened in the upper left part of the lint collection transparent box. A lint conveying pipe is fixedly connected to the middle of the right end of the lint collection transparent box. The end of the lint conveying pipe away from the collection box fixing frame is fixedly connected to the miniature negative pressure fan. A lint adsorption nozzle is fixedly connected to the middle of the lower end of the miniature negative pressure fan. The end of the lint adsorption nozzle away from the miniature negative pressure fan extends to the upper left side inside the transparent detection rotating box.

[0021] By adopting the above technical solution—using negative pressure to adsorb the drilled filaments and collect them in a transparent box—fine filaments can be collected efficiently. The transparent box facilitates observation and statistics, avoids filament residue from affecting test results, and improves data accuracy.

[0022] Preferably, the collection box fixing frame is detachably connected to the velvet collection transparent box via fixing bolts and fixing bolt through holes.

[0023] By adopting the above technical solution, the collection box fixing frame and the lint collection transparent box are installed by a threaded movable method, which can realize the detachable fixing of the collection box, thereby facilitating quick and easy disassembly and assembly of the collection box for cleaning or replacement. The operation is simple and improves the efficiency of post-testing processing.

[0024] Preferably, the filament conveying pipe communicates with the interior of the filament collecting transparent box through the filament inlet hole.

[0025] By adopting the above technical solution, the adsorbed filaments can be smoothly transported to the collection box, ensuring smooth filament transport, avoiding leakage, ensuring that all drilled filaments are collected, and further improving the reliability of the detection data.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In this invention, the down jacket detection rotating device achieves dynamic operation of the rotating box through rotation drive. The sealed door structure ensures a closed detection environment and facilitates observation and operation. The bidirectional clamping component can stably fix the down jacket. The anti-damage pad avoids fabric damage. The symmetrical distribution ensures balanced force. The detachable design improves adaptability. The bottom elastic friction component uses the elasticity of the spring to drive the rubber head and protruding particles to simulate the friction and compression in real wear. The top impact structure achieves multi-point impact through cylinder drive. The combination of the two reproduces complex force scenarios. The overall synergistic effect can comprehensively simulate the force state of clothing during use, fully stimulate the potential risk of down leakage, and at the same time take into account the convenience of operation and the stability of detection, providing a reliable simulation basis for down leakage detection.

[0028] 2. In this invention, the down-leaking adsorption and collection structure generates suction through a negative pressure fan, efficiently capturing the down fibers that have leaked out during the detection process via an adsorption nozzle. These fibers are then guided into a transparent collection box through a delivery pipe, achieving full-process collection of down fibers. The detachable design of the fixing frame and the collection box ensures stable installation and facilitates quick disassembly and cleaning after detection. In addition, the transparent box allows for direct observation of the amount of down fibers, facilitating accurate measurement of the degree of down leakage. This ensures a tight fit of the overall structure, enabling the collection of fine down fibers and preventing residues from affecting the test results. Furthermore, the invention is easy to operate, effectively improving the accuracy and efficiency of down leakage detection and providing reliable data support for the quality assessment of down jackets.

The inner wall of the transparent detection rotating box 72 is respectively connected to four... Two down jacket clamping and fixing structures 77 are provided, each consisting of a clamping mounting frame 771. Each clamping mounting frame 771 has through-holes 772 on all four sides of its left end. A bidirectional clamping assembly 774 is fixedly connected to the upper end of the clamping mounting frame 771, with its lower part located within the clamping mounting frame 771. A bidirectional clamping limiting port 773 is provided in the middle of the left end of the clamping mounting frame 771. The two down jacket clamping and fixing structures 77 are arranged in a mirror image. The clamping mounting frame 771 is detachably connected to the transparent detection rotating box 72 via four screw mounting holes 772 and four fixing screws 76. The clamping assembly 774 includes a drive motor 7741. The output end of the drive motor 7741 passes through the upper middle part of the clamping mounting frame 771 and is fixedly connected to a bidirectional threaded rod 7742.

The output end of the cylinder 91 passes through the upper middle of the transparent detection rotating box 72 and is fixedly connected to a mounting base 92. Nine connecting rods 93 are fixedly connected at equal intervals to the lower end of the mounting base 92. Each of the nine connecting rods 93, away from the mounting base 92, is fixedly connected to a top impact rubber head 94. All nine top impact rubber heads 94 contact the upper fabric of the down jacket.

[0044] Through the above scheme: the rotary driver 71 drives the transparent detection turntable 72 to rotate, which, together with the down jacket clamping and fixing structure 77 with mirror distribution on the left and right, the drive motor 7741 in the bidirectional clamping component 774 drives the bidirectional threaded rod 7742 to move the fixed block 7743 to drive the garment clamping head 7745 to firmly clamp the down jacket.

[0045] In this embodiment, the lint adsorption and collection structure 10 includes a collection box fixing frame 101, a lint collection transparent box 104, and a miniature negative pressure fan 107. The lower end of the collection box fixing frame 101 is fixedly connected to the upper left part of the transparent detection rotating box 72. A collection box placement groove 102 is opened at the left end of the collection box fixing frame 101. A fixing bolt 103 is threadedly connected to the upper right end of the collection box fixing frame 101. The lint collection transparent box 104 is snapped into the collection box placement groove 102.

The end of the lint adsorption nozzle 108 away from the miniature negative pressure fan 107 extends to the upper left side of the transparent detection rotating box 72. The collection box fixing frame 101 is detachably connected to the lint collection transparent box 104 through the fixing bolt 103 and the fixed bolt through hole 105. The lint conveying pipe 109 communicates with the interior of the lint collection transparent box 104 through the lint inlet hole 106.

[0046] Through the above scheme: the micro negative pressure fan 107 generates negative pressure, which is used to adsorb the lint drilled out of the transparent detection rotating box 72 through the lint adsorption nozzle 108. The lint enters the lint collection transparent box 104 through the lint conveying pipe 109 and the lint inlet hole 106. The collection box fixing frame 101 fixes the lint collection transparent box 104 with fixing bolts 103 and fixing bolt through holes 105. The collection box placement groove 102 ensures stable installation. The transparent design makes it easy to observe the amount of lint, and the detachable connection makes it easy to clean and count. Thus, this structure realizes the collection of lint throughout the whole process, avoids the residue of fine lint, ensures the accuracy of detection data, and improves the reliability of lint detection.

[0047] It should be noted that this invention is a down leakage detection device for down jacket production. In use, firstly, the down jacket to be tested is placed into the transparent detection rotating box 72 through the visible sealing door 73. The drive motor 7741 of the down jacket clamping and fixing structure 77 drives the bidirectional threaded rod 7742, causing the moving fixing block 7743 to drive the garment clamping jaws 7745 to clamp the fabric at both ends of the down jacket. The anti-damage clamping pad 7747 protects the fabric, while the auxiliary fixing magnet 7746 further stabilizes the down jacket. After closing the visible sealing door 73, the equipment parameters can be adjusted through the control panel 5 and parameter display screen 6, thereby achieving automated detection, i.e., rotating the drive unit 71. The transparent detection rotating box 72 is driven to rotate. The elastic support spring 82 of the bottom elastic friction impact component 8 drives the bottom friction rubber head 83 and friction protrusions 84 to rub the bottom of the down jacket. In addition, the cylinder 91 of the top adjustable impact structure 9 drives the top impact rubber head 94 to impact the upper fabric of the down jacket up and down. At the same time, the micro negative pressure fan 107 of the down adsorption and collection structure 10 can adsorb the down fibers through the down adsorption nozzle 108 and send them into the down collection transparent box 104 through the down fiber conveying pipe 109. Therefore, this device improves the authenticity and accuracy of down detection by simulating real force in multiple directions and collecting down fibers efficiently. It is also easy to operate and suitable for quality control in down jacket production.
