Description

Technical Field

[0001] This utility model belongs to the field of down jacket performance testing equipment, specifically a down-proof performance tester. Background Technology

[0002] The quality of down jackets is defined by various performance evaluation standards. Down-proof performance is a crucial indicator, as it relates to the retention of down feathers after prolonged use, which in turn affects the down's warmth retention. Therefore, down-proof performance is a vital aspect of down jacket quality testing. Current laboratory down-proof testing primarily uses the garment rotating box method in GB / T 14272-2021. This method involves rapid testing using equipment with automatically controlled rotation speed and duration. The number of down feathers and feathers that emerge from the fabric surface after testing is counted to evaluate the sample's down-proof performance. However, the main challenge of the rotating box method lies in collecting the down feathers electrostatically adsorbed on the inner wall of the rotating box. Collecting down feathers from the inner wall of the box usually requires considerable effort from the operator. A single garment sample may contain thousands of down feathers, placing a significant workload on the testers each time this process is conducted, and thus requires improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a down-proof performance tester.

[0004] The present invention adopts the following technical solution:

[0005] A down-proof performance tester includes a base, a control console, a rotating box, an ion fan, a ventilation mechanism, and a collection mechanism. The control console is mounted on the base. One side of the rotating box is connected to the control console and driven by the control console to rotate around an axis. The rotating box has a cavity for placing fabric, and a door for opening or sealing the cavity is formed on the side. The bottom of the cavity also has an outlet for discharging down. The ion fan is located on the other side of the rotating box and faces the rotating box. The ventilation mechanism is mounted on the rotating box and includes ventilation holes, first guide rails, a baffle plate, and a fixing component. There are several ventilation holes formed on the rotating box on the side opposite to the ion fan. The first guide rails are formed on both sides of the ventilation holes. The baffle plate is movably mounted between two first guide rails to open or seal the ventilation holes. The fixing component is located between the first guide rails and the baffle plate to fix the baffle plate to the first guide rails. The collection mechanism is connected to the outlet and can seal or open the outlet to collect down.

[0006] Preferably, the collection mechanism includes a second guide rail, a collection box, a sealing plate, a filter screen, and a negative pressure fan. The second guide rail is formed on both sides of the outlet. The collection box is movably mounted on the second guide rail to cover the outlet, and the collection box has a vertically continuous structure. The sealing plate is movably mounted in the collection box to seal or open the outlet. The filter screen is mounted in the collection box and located below the sealing plate to collect down feathers. The negative pressure fan is mounted on the base opposite the bottom of the collection box and generates a downward suction force at the collection box.

[0007] Preferably, the second guide rail extends in a direction parallel to the axis of the rotating box, the moving direction of the sealing plate is also parallel to the axis of the rotating box, and there is a gap between the bottom of the collection box and the negative pressure blower.

[0008] Preferably, the first guide rail includes a first connecting section and a first extension section. The first connecting section is formed outward perpendicular to the side of the rotating box, and its length is adapted to the thickness of the baffle plate. The first extension section extends inward perpendicularly from the top surface of the connecting section, and the baffle plate is movably disposed between the first extension section and the side of the rotating box.

[0009] Preferably, the fixing component includes a limiting plate, a positioning hole, a fixing screw hole, and a fixing bolt. The limiting plate protrudes outward from the top surface of the baffle plate and can contact the top surface of the first guide rail. The positioning hole is formed through the connecting section. There are two fixing screw holes, which are formed on the side of the limiting plate respectively, and can be opposite to the positioning hole when the ventilation hole is opened or sealed. The fixing bolt passes through the positioning hole and the fixing screw hole in sequence to fix the baffle plate on the guide rail.

[0010] Preferably, a support column is provided on the base, the support column is rotatably connected to the other side of the rotating box, and a clearance groove is formed on the shielding plate to allow space for the connection between the support column and the rotating box.

[0011] Preferably, the second guide rail includes a second connecting section and a second extension section, the second connecting section extending vertically downward; the second extension section extending inward from the second connecting section; and the top surface of the collection box protruding outward has a protrusion that can be slidably disposed between the second extension section and the bottom surface of the rotating box.

[0012] Preferably, the control console is equipped with a drive motor for driving the rotating box and a controller for controlling the rotation of the drive motor. The control console is also equipped with a control screen that is connected to the controller and presets the rotation speed and rotation duration.

[0013] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: After the rotation box is completed, the operator raises the baffle plate and starts the ion fan, which blows the ion fan into the rotation box through the ventilation hole, which can eliminate the static electricity in the rotation box and cause the down adhering to the inner wall of the rotation box to fall off naturally. The down is then collected by the collection mechanism below, making the collection of down more convenient and faster, and effectively improving the detection efficiency.

[0014] The sealing plate keeps the rotating chamber sealed while it rotates, preventing it from affecting the testing of the down jackets inside. When collecting down from the inner wall of the rotating chamber, the sealing plate can be removed, and a negative pressure fan generates a downward suction force on the collection box. Gas flows into the rotating chamber through the vent and flows out from the outlet. Down on the inner wall of the rotating chamber can fall onto the filter screen of the collection box. After collection, the collection box can be removed and the down can be counted. The collection can be completed automatically, reducing the workload of the operators and further improving work efficiency.

[0015] The collection box and the sealing plate move in the same direction as the rotating shaft of the rotating box, so no additional fixing is required and they will not be thrown out when the rotating box is rotating. This makes it easier for operators to pick up the sealing plate and the collection box while improving safety.

[0016] Since the collection box needs to rotate with the rotating box, there is a gap between the negative pressure fan and the collection box so that it will not affect the operation of the rotating box. Also, the down itself is relatively light, so even if there is a gap that weakens the suction of the negative pressure fan, it will not affect the down being sucked out.

[0017] The fasteners can secure the baffle plate when the ventilation holes are opened or sealed, preventing it from being thrown out when the ion fan eliminates static electricity or when the rotating box is spinning. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 8 As shown, a down-proof performance tester includes a base 1, a control console 2, a rotating box 3, an ion fan 4, a ventilation mechanism 5, and a collection mechanism 6.

[0029] The control console 2 is mounted on the base 1. The control console 2 integrates a drive motor and a controller, and also has a control panel 21 for preset rotation speed and rotation time. The drive motor is a servo motor, which can precisely control the rotation position to ensure accurate reset of the device after stopping.

[0030] One side of the rotating box 3 is connected to a drive motor inside the control console 2, and is driven by the control console 2 to rotate around its axis. The rotating box 3 has a cavity 31 for holding fabric, and a door 32 is formed on its side that can open or seal the cavity 31. The bottom of the cavity 31 also has an outlet 33 for discharging down from the cavity 31. Specifically, a support column 11 is provided on the base 1, and the support column 11 is rotatably connected to the other side of the rotating box 3. The rotating box 3 and the support column 11 are rotatably connected by a bearing.

[0031] Ionizing fan 4 is located on the other side of rotating box 3 and faces rotating box 3. Ionizing fan 4 is a common static eliminator and is not the focus of this application. Its structure and selection will not be described in detail here.

[0032] A ventilation mechanism 5 is installed on the rotating box 3, including ventilation holes 51, first guide rails 52, baffles 53, and fixing members 54. Several ventilation holes 51 are formed on the rotating box 3 on the side opposite to the ion fan 4. The first guide rails 52 are formed on both sides of the ventilation holes 51. The baffles 53 are movably disposed between the two first guide rails 52 to open or seal the ventilation holes 51. The fixing members 54 are disposed between the first guide rails 52 and the baffles 53 to fix the baffles 53 to the first guide rails 52. After the rotating box 3 is closed, the operator raises the baffles 53 and starts the ion fan 4, allowing it to blow into the rotating box 3 through the ventilation holes 51. This eliminates static electricity inside the rotating box 3, causing the down feathers adhering to the inner wall of the rotating box 3 to fall off naturally.

[0033] Specifically, the first guide rail 52 includes a first connecting section 521 and a first extension section 522. The first connecting section 521 is formed outward perpendicular to the side of the rotating box 3, and its length is adapted to the thickness of the baffle plate 53. The first extension section 522 extends inward perpendicularly from the top surface of the connecting section, and the baffle plate 53 is movably disposed between the first extension section 522 and the side of the rotating box 3.

[0034] Furthermore, the fixing component 54 includes a limiting plate 541, a positioning hole 542, a fixing screw hole 543, and a fixing bolt 544. The limiting plate 541 protrudes outward from the top surface of the baffle plate 53 and can contact the top surface of the first guide rail 52. The positioning hole 542 is formed through the connecting section. There are two fixing screw holes 543, which are formed on the side of the limiting plate 541 respectively, and can be opposite to the positioning hole 542 when the ventilation hole 51 is opened or sealed. The fixing bolt 544 passes through the positioning hole 542 and the fixing screw hole 543 in sequence to fix the baffle plate 53 on the guide rail. The fixing component 54 can fix the baffle plate 53 when the ventilation hole 51 is opened or sealed, so as to avoid affecting the ion fan 4 in eliminating static electricity or being thrown out when the rotating box 3 rotates.

[0035] Preferably, the shielding plate 53 is formed with a clearance groove 531 for the connection between the support column 11 and the rotating box 3. The distribution of the ventilation holes 51 on the rotating box 3 is also adapted to the shape of the shielding plate 53, ensuring its installation passability while preventing some ventilation holes 51 from being unblocked.

[0036] The collection mechanism 6 is connected to the outlet 33 and can seal or open the outlet 33 to collect down. The collection mechanism 6 includes a second guide rail 61, a collection box 62, a sealing plate 63, a filter screen 64, and a negative pressure fan 65. The second guide rail 61 is formed on both sides of the outlet 33. The collection box 62 is movably mounted on the second guide rail 61 to cover the outlet 33, and the collection box 62 has a vertically continuous structure. The sealing plate 63 is movably mounted in the collection box 62 to seal or open the outlet 33. The filter screen 64 is mounted in the collection box 62 and located below the sealing plate 63 to collect down. The filter screen 64 is usually also equipped with electrostatic dust removal paper to prevent down from adsorbing and getting stuck on the filter screen 64. The negative pressure fan 65 is mounted on the base 1 and opposite to the bottom of the collection box 62, generating a downward suction force at the collection box 62. The sealing plate 63 can keep the rotating box 3 sealed when it rotates, so as to avoid affecting the testing of the down jacket inside. When collecting down from the inner wall of the rotating box 3, the sealing plate 63 can be removed. The negative pressure fan 65 generates a downward suction force on the collection box 62. The gas flows into the rotating box 3 through the vent and flows out from the outlet 33. The down on the inner wall of the rotating box 3 can fall onto the filter screen 64 of the collection box 62. After collection, the collection box 62 can be removed and the down can be counted. The collection can be completed automatically, reducing the workload of the operator and further improving work efficiency.

[0037] Specifically, the second guide rail 61 includes a second connecting section 611 and a second extension section 612. The second connecting section 611 extends vertically downwards; the second extension section 612 extends inwards from the second connecting section 611; the top surface of the collection box 62 protrudes outwards with a protrusion 621 that is slidably disposed between the second extension section 612 and the bottom surface of the rotating box 3. The second guide rail 61 extends in a direction parallel to the axis of the rotating box 3, and the moving direction of the sealing plate 63 is also parallel to the axis of the rotating box 3. There is a gap between the bottom of the collection box 62 and the negative pressure fan. Since the moving directions of the collection box 62 and the sealing plate 63 are both parallel to the axis of rotation of the rotating box 3, no additional fixing is required, and they will not be thrown out when the rotating box 3 rotates. This facilitates the operator in handling the sealing plate 63 and the collection box 62 while improving safety. Since the collection box 62 needs to rotate with the rotating box 3, there is a gap between the negative pressure fan 65 and the collection box 62, so that it will not affect the operation of the rotating box 3. Moreover, the down itself is relatively light, so even if there is a gap that causes the suction of the negative pressure fan 65 to weaken, it will not affect the down being sucked out.

[0038] In use, following the method described in GB / T 14272-2021, "Garment Rotary Chamber 3 Method for Down-proof Test," the garment to be tested is placed in the rotating chamber 3, the door is closed, and the rotation speed and duration are preset on the control panel 21 before starting the device. After the rotating chamber 3 completes its rotation, the garment and the silicone rubber shaped ball are removed sequentially, and the down count is recorded. Next, the operator removes the fixing bolts 544, raises the baffle plate 53 along the first guide rail 52, and re-tightens the fixing bolts 544 to secure the baffle plate 53. At the same time, the sealing plate 63 is pulled out, connecting the outlet 33 to the collection box 62. Then, the ion fan 4 and the negative pressure fan 65 are started. The down adsorbed on the inner wall of the rotating chamber 3 is de-staticated by the ion fan 4 and is drawn into the filter 64 in the collection box 62 by the negative pressure fan 65. Finally, the collection box 62 is pulled out from the second guide rail 61, and the down count is recorded. This application eliminates the need for operators to perform cumbersome down-hanging operations on the inner wall of the rotating box 3, reducing the burden on operators, improving detection efficiency, and demonstrating high practicality.

[0039] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
