Description

Technical Field

[0001] This utility model relates to the field of down processing technology, specifically a compression device suitable for down products. Background Technology

[0002] Down products encompass finished and semi-finished products such as down comforters, down jackets, and down pillows, as well as processed bulk down raw materials. After completing core processing steps such as washing, drying, and sorting (finished and semi-finished products require additional filling), these products need to be compressed into special packaging bags for easy transportation, thereby effectively reducing space usage.

[0003] Currently available devices often rely solely on a single screw drive structure for their pressure plate drive, lacking effective guiding and limiting components. Under prolonged stress or uneven load, the pressure plate is prone to tilting, such as edge curling or localized shifting. This causes the contact between the pressure plate and the down product to change from full coverage to partial contact. Some areas are firmly pressed, while others are not pressed at all, ultimately resulting in significant differences in density and thickness across different areas of the down product. Some areas remain fluffy, making it impossible to achieve uniform volume reduction. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a compression device suitable for down products, which solves the problems of low efficiency, narrow application range, and down leakage and contamination of traditional devices, improves compression efficiency, uniformity and ease of operation, while reducing costs and adapting to diverse needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compression device suitable for down products, comprising a base, an L-shaped connecting plate fixedly installed on the top of the base, a drive motor fixedly installed on the top of the L-shaped connecting plate, a lead screw coaxially fixedly connected to the output end of the drive motor, a linkage sleeve threaded on the outer side of the lead screw, a connecting plate fixedly installed at the bottom of the linkage sleeve to ensure balanced force on the connecting plate and prevent the pressure plate from tilting, and a pressure plate for vertically compressing down detachably connected to the bottom of the connecting plate by positioning bolts; a sliding groove is provided on the upper end face of the base, a connecting frame is fixedly installed in the sliding groove, a suction fan for discharging compressed gas is fixedly installed at the top of the connecting frame, and a limiting sleeve is sleeved and fixedly installed around the connecting frame; a compression box for accommodating down products is slidably installed on the upper end face of the limiting sleeve along its length direction, a linkage motor is fixedly installed on both outer walls of the compression box, and the output end of the linkage motor penetrates through the side wall of the compression box and is fixedly connected to an adjustment device for laterally limiting down.

The internally threaded sleeve rod is threadedly engaged with the threaded rod, and a limiting plate that slides against the inner sidewall of the compression box is fixedly connected to the end of the internally threaded sleeve rod away from the threaded rod. A retractable and foldable connecting plate is fixedly installed between the top of the limiting plate and the inner top wall of the compression box.

[0007] Preferably, the surface of the exhaust plate fixedly installed on the bottom wall inside the compression box has several evenly distributed exhaust holes. The exhaust holes are connected to the inner cavity of the connecting frame so that the gas generated by compression can enter the connecting frame through the exhaust holes. A storage box for collecting down debris is slidably installed in the horizontal direction inside the base.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-5 A compression device for down products includes a base 1, an L-shaped connecting plate 10 fixedly mounted on the top of the base 1, a drive motor 11 fixedly mounted on the top of the L-shaped connecting plate 10, a lead screw 15 coaxially fixedly connected to the output end of the drive motor 11, a linkage sleeve 20 provided on the outer side of the lead screw 15, a connecting plate 18 fixedly mounted at the bottom of the linkage sleeve 20 to ensure balanced force on the connecting plate 18 and prevent the pressure plate 13 from tilting, and a pressing screw for vertically compressing down detachably connected to the bottom of the connecting plate 18 by a positioning bolt 17. Plate 13; The upper surface of the base 1 has a sliding groove, and a connecting frame 19 is fixedly installed in the sliding groove. A suction fan 14 for discharging compressed gas is fixedly installed at the top of the connecting frame 19. A limiting sleeve plate 2 is sleeved and fixedly installed around the connecting frame 19. A compression box 6 for accommodating down products is slidably installed on the upper surface of the limiting sleeve plate 2 along its length. A linkage motor 7 is fixedly installed on both outer walls of the compression box 6. The output end of the linkage motor 7 passes through the side wall of the compression box 6 and is fixedly connected to an adjustment device for lateral limiting of down.

[0023] In use, first slide the compression box 6 outward along the strip rail on the inner side wall of the limiting sleeve 2 (the slider on the outer side wall of the compression box 6 is adapted to the rail), and put the down product to be compressed into the compression box 6; then push the compression box 6 back to the working position of the corresponding connecting frame 19 inside the limiting sleeve 2, and tighten the limiting bolt on one side of the limiting sleeve 2 so that the end of the bolt abuts against the outer side wall of the compression box 6 to complete the locking; then start the drive motor 11 at the top of the L-shaped connecting plate 10, and the motor output end drives the lead screw 15 to rotate; since the linkage sleeve 20 on the outer side of the lead screw 15 is fixedly connected to the connecting plate 18, and the two sliding rods 12 symmetrically installed on the upper end of the connecting plate 18 pass through the L-shaped connecting plate 10 and slide in fit (to prevent the connecting plate 18 from rotating with the lead screw 15), the linkage sleeve 20 will move smoothly downward along the axis of the lead screw 15, thereby driving The connecting plate 18 and the bottom pressure plate 13 move vertically downwards simultaneously. When the pressure plate 13 moves downwards, the silicone elastic buffer layer at its bottom will first come into contact with the down. The grid-like raised texture on the surface of the buffer layer can enhance the friction with the down and prevent the down from shifting during compression. At the same time, the suction fan 14 at the top inside the connecting frame 19 is activated. The gas generated by the compression of the down enters the inner cavity of the connecting frame 19 through the uniform exhaust holes of the exhaust plate 9, and is then quickly discharged out of the device by the suction fan 14 to avoid gas stagnation affecting the compression efficiency. A small amount of down debris generated during compression will fall into the storage box 3 connected to the bottom of the connecting frame 19 with the airflow. The force-balanced design of the connecting plate 18 can prevent the pressure plate 13 from tilting. The sliding guide action of the slide rod 12 further ensures that the pressure plate 13 moves vertically until the down is compressed to the target thickness.

[0024] like Figure 2 or Figure 5 As shown, the adjusting device includes a threaded rod 21 and an internally threaded sleeve 16. One end of the threaded rod 21 is coaxially and fixedly connected to the output end of the linkage motor 7. The internally threaded sleeve 16 is threadedly engaged with the threaded rod 21, and a limiting plate 8 that slides against the inner wall of the compression box 6 is fixedly connected to the end of the internally threaded sleeve 16 away from the threaded rod 21. A retractable folding connecting plate 22 is fixedly installed between the top of the limiting plate 8 and the inner top wall of the compression box 6. The folding connecting plate 22 is used to seal the gap between the limiting plate 8 and the compression box 6 to prevent down from leaking out of the gap. During the above-mentioned use, if it is necessary to adjust according to the down production... When the volume of the product is adjusted and the lateral limit is reached, the linkage motors 7 on both sides of the compression box 6 can be activated. The output end of the motor drives the threaded rod 21 to rotate, and the internal threaded sleeve 16 that is threaded with the threaded rod 21 moves in the horizontal direction, thereby pushing the limiting plate 8 to slide on the inner side wall of the compression box 6 (the limiting plate 8 and the inner side wall of the compression box 6 are tightly fitted). At the same time, the retractable foldable connecting plate 22 between the top of the limiting plate 8 and the inner top wall of the compression box 6 extends and retracts synchronously with the movement of the limiting plate 8, always sealing the gap between the two, completely preventing down from leaking out of the gap, ensuring the lateral limiting effect while preventing down loss.

[0025] like Figure 2 or Figure 4As shown, the exhaust plate 9, which is fixedly installed on the bottom wall of the compression box 6, has several evenly distributed exhaust holes on its surface. The exhaust holes are connected to the inner cavity of the connecting frame 19 so that the gas generated by compression can enter the connecting frame 19 through the exhaust holes. A storage box 3 for collecting down debris is slidably installed in the base 1 along the horizontal direction. The opening end of the storage box 3 is connected to the bottom of the connecting frame 19, and a handle 4 for easy pulling and cleaning is fixedly installed on the outer end of the storage box 3. During the above-mentioned use, as the pressure plate 13 squeezes the down product, the gas inside the down passes through the several evenly distributed exhaust holes on the surface of the exhaust plate 9 on the bottom wall of the compression box 6. The exhaust vents are evenly distributed and enter the inner cavity of the connecting frame 19. At this time, the suction fan 14 at the top of the connecting frame 19 is activated to quickly expel the gas in the cavity to the outside of the device, so as to avoid gas stagnation affecting the compression efficiency and compression effect. At the same time, a small amount of down debris generated during the compression process will fall into the storage box 3 connected to the bottom of the connecting frame 19 through the exhaust vents. After the compression work is completed, the operator can hold the handle 4 at the outer end of the storage box 3 and pull the storage box 3 out horizontally from the inside of the base 1 to clean the collected down debris. After cleaning, the storage box 3 can be pushed back to its original position to restore the device to the standby state.

[0026] like Figure 2 or Figure 5 As shown, a strip-shaped slide rail is provided on the inner side wall of the limiting sleeve 2 along its length. A slider adapted to the strip-shaped slide rail is fixed on the outer side wall of the compression box 6. A limiting bolt for locking the compression box 6 is threaded through one side of the limiting sleeve 2. The end of the limiting bolt abuts against the outer side wall of the compression box 6 to ensure the stability of the compression box 6 during compression. During the above-mentioned use, when the compression box 6 is pulled out, the slider on the outer side wall of the compression box 6 slides smoothly along the strip-shaped slide rail on the inner side wall of the limiting sleeve 2, effectively ensuring the smoothness and stability of the compression box 6 pulling process and avoiding the displacement of down due to sliding jamming. When the compression box 6 is pushed back to the working position, the limiting bolt on one side of the limiting sleeve 2 is tightened so that the end of the bolt abuts tightly against the outer side wall of the compression box 6, which can firmly lock the compression box 6 in the current position, preventing the compression box 6 from shifting due to vibration caused by the operation of the drive motor 11 and the linkage motor 7 or the squeezing force applied by the pressure plate 13 during subsequent compression, thus ensuring the stability of the compression operation.

[0027] like Figure 2 or Figure 4As shown, two sliding rods 12 are symmetrically fixedly installed on the upper end of the connecting plate 18. Both sliding rods 12 pass through the L-shaped connecting plate 10 and slide in cooperation with the L-shaped connecting plate 10. This is to prevent the connecting plate 18 from rotating with the lead screw 15 and to ensure the vertical compression accuracy of the pressure plate 13. During the above-mentioned use, when the drive motor 11 is started to drive the lead screw 15 to rotate, the linkage sleeve 20 that is threaded with the lead screw 15 will move along the axial direction of the lead screw 15, thereby driving the bottom fixed connecting plate 18 to move synchronously. At this time, the two sliding rods 12 symmetrically fixed on the upper end of the connecting plate 18 slide along the through hole of the L-shaped connecting plate 10, which can effectively limit the rotation of the connecting plate 18 with the lead screw 15, ensuring that the connecting plate 18 only moves smoothly in the vertical direction, thereby driving the pressure plate 13 to maintain the vertical movement trajectory, avoiding the pressure plate 13 tilting and causing uneven down compression, significantly improving the vertical compression accuracy, and ensuring the consistency of the shape of the down product after compression.

[0028] like Figure 2 or Figure 3 As shown, an elastic buffer layer is fixedly installed at the bottom of the pressure plate 13. The elastic buffer layer is made of silicone and is used to prevent the pressure plate 13 from directly damaging the down fibers. The surface of the elastic buffer layer has several raised textures that are evenly distributed in a grid pattern. The raised textures are used to enhance the friction between the pressure plate 13 and the down product and prevent the down from shifting during compression. During the above-mentioned use, when the pressure plate 13 moves vertically downward to squeeze the down product, the silicone elastic buffer layer at the bottom of the pressure plate 13 comes into direct contact with the down. The elastic properties of silicone can avoid hard contact between the pressure plate 13 and the down, preventing the down fibers from being crushed or broken. At the same time, the evenly distributed raised textures on the surface of the elastic buffer layer can greatly enhance the friction with the surface of the down product, effectively preventing the down from shifting due to the pressure during compression, ensuring that the down is always in the preset compression area, and ensuring the compression accuracy and final effect.

[0029] like Figure 1 As shown, an antistatic layer is fixedly installed on the side of the limiting plate 8 facing the down and on the inner wall of the compression box 6. The antistatic layer is made of antistatic non-woven fabric or conductive silicone. It is used to prevent the down from being attracted to the limiting plate 8 or the inner wall of the compression box 6 due to static electricity generated by friction, ensuring that the down can be easily removed after compression. During the above-mentioned use, when the down product comes into contact with the side of the limiting plate 8 facing the down and the inner wall of the compression box 6 and friction occurs, the antistatic layer (antistatic non-woven fabric or conductive silicone) fixed on the limiting plate 8 and the inner wall of the compression box 6 can quickly eliminate the static electricity generated by friction, preventing the down from being attracted to the surface of the limiting plate 8 or the inner wall of the compression box 6 due to static electricity. After the compression work is completed, the operator can easily remove the down product without the need for additional cleaning of the attracted down, improving the convenience of operation and reducing down loss.

[0030] like Figure 1 or Figure 2As shown, an anti-slip pad 5 is fixedly installed at the bottom of the base 1. The anti-slip pad 5 is made of rubber and has anti-slip texture on its surface. It is used to increase the friction between the base 1 and the ground and prevent the compression device from shifting during operation. During the above-mentioned use, when the drive motor 11 and the linkage motor 7 vibrate, or when the pressure plate 13 applies a large squeezing force to the down product, the rubber anti-slip pad 5 at the bottom of the base 1 can significantly increase the friction between the base 1 and the ground through the anti-slip texture on its surface. This effectively resists the tendency of shifting caused by vibration and squeezing force, ensuring that the entire compression device always remains stable, providing a safe and reliable working environment for the operator, and avoiding the impact of device shifting on compression accuracy.
