DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-Figure 10 As shown, a pressure packaging device for parachutes provided by an embodiment of the present invention includes a bracket 101, a servo motor 102 is fixedly installed in the bracket 101, and the driving end of the servo motor 102 is rotatably connected to a disc 104, a square tube 105 is fixedly installed on the upper surface of the disc 104, and a fixing opening is opened at the top of the square tube 105 near the middle, and a hydraulic cylinder 106 is fixedly installed in the fixing opening, and a block 108 is fixedly installed at the telescopic end of the hydraulic cylinder 106, and the upper surface of the block 108 A mounting plate 109 is fixedly installed on the surface, a mounting opening is also opened at the top of the square tube 105, and a limit rod 107 is movably arranged in the mounting opening, and the top of the limit rod 107 is connected to the lower surface of the block 108. It also includes: a bag-opening unit, which is arranged below the mounting plate 109 and is used to open the parachute bag for packaging the parachute; a lifting unit, which is arranged on the upper surface of the disc 104 and is used to lift the parachute bag to be squeezed; and a compression unit, which is arranged in the mounting plate 109 and is used to compress the parachute in the parachute bag.

[0031] When packing the parachute, the parachute bag can be placed on the lifting unit with the help of manual labor, and the parachute bag can be opened by the bag-opening unit, and the mounting plate 109 can be driven to rise and fall by the hydraulic cylinder 106, so that the distance between the bag-opening unit and the lifting unit can be adjusted according to the length of the parachute bag, so that when the bag-opening unit opens the parachute bag, the lifting unit can just lift the parachute bag. At the same time, the servo motor 102 can drive the rotating shaft 103, and the rotating shaft 103 drives the disc 104 to rotate, so that the parachute bag rotates with the disc 104. When the disc 104 rotates, the compression unit can enter the parachute bag, apply uniform and appropriate pressure to the parachute, and achieve the purpose of compressing the parachute in the parachute bag, which can effectively reduce the space occupied by the parachute in the parachute bag and avoid the parachute being packed too loosely. The internal structure is prone to displacement during transportation or storage, affecting subsequent normal use. The packaging quality of the parachute is improved, and its reliability and safety during use are guaranteed. When the parachute in the parachute bag is compressed, the compression unit can be removed from the parachute bag and the support of the parachute bag by the bag support unit can be released. At this time, the parachute bag falls to the surface of the lifting unit and continues to rotate with the disc 104. It can be subsequently picked up and transferred manually or mechanically. The device effectively realizes the continuous compression packaging of the parachute. Compared with the traditional manual pressure packaging method, it effectively improves the packaging efficiency, can meet the needs of large-scale production, and can ensure that uniform and appropriate pressure is applied to the parachute, avoiding the situation where the packaging is too loose or too tight, improving the packaging quality of the parachute, ensuring its reliability and safety during use, and achieving better use effect.

[0032] As an embodiment of the present invention, please refer to Figure 1 , Figure 3 and Figure 4The bag-supporting unit includes a fixed support plate 201 which is fixedly arranged in a ring shape at an equal distance on the lower surface of the mounting plate 109, and a first rubber block 202 distributed in a rectangular array is fixedly arranged on the outer wall of the fixed support plate 201 on one side away from the block 108, a fixed cylinder 203 is fixedly arranged on the outer wall around the block 108, a telescopic rod 205 is movably installed in the fixed cylinder 203, a first spring 206 is fixedly installed on the inner wall of the fixed cylinder 203, and the end of the first spring 206 is connected to one end of the telescopic rod 205, a movable support plate 208 is fixedly installed on the other end of the telescopic rod 205, and a second rubber block 209 distributed in a rectangular array is fixedly arranged on the outer wall of the movable support plate 208 close to the block 108, a limiting opening 204 is provided on the outer wall of the fixed cylinder 203, a limiting plate 207 is fixedly installed on the outer wall of the telescopic rod 205, and the limiting plate 207 is located in the limiting opening 204, the block 1 The first rubber block 202 on the outer wall of the fixed support plate 201 and the second rubber block 209 on the outer wall of the dynamic support plate 208 can increase the friction between the first rubber block 202 and the second rubber block 209 on the outer wall of the dynamic support plate 208 and the umbrella bag, so that the umbrella bag drives the dynamic support plate 208 to move, and the dynamic support plate 208 drives the telescopic rod 205 to move in the fixed tube 203, so that the first spring 206 is stretched. When the umbrella bag has space to be connected to the outside of the fixed support plate 201, the umbrella bag can be connected to the outside of the fixed support plate 201 at the same time and the umbrella bag is released. At this time, under the resetting action of the first spring 206, the dynamic support plate 208 can be moved away from the fixed support plate 201, so as to prop up the umbrella bag.

[0033] As an embodiment of the present invention, please refer to Figure 3The bag unpacking assembly includes an electric telescopic member 301 fixedly arranged on the outer wall of the block 108, the telescopic end of the electric telescopic member 301 penetrates the movable support plate 208, and a movable plate 302 is fixedly installed on the telescopic end of the electric telescopic member 301, a connecting frame 303 is fixedly installed on the outer wall of the movable plate 302, and the connecting frame 303 penetrates the movable support plate 208, and a traction plate 304 is fixedly installed on the end of the connecting frame 303, and the traction plate 304 is located between the movable support plate 208 and the block 108. When the umbrella bag is supported by the fixed support plate 201 and the movable support plate 208 at the same time, the movable plate 302 can also be driven to move by the electric telescopic member 301, so that the movable plate 302 can be moved. The outer walls of the movable plate 302 and the movable support plate 208 are in contact with each other to ensure that the movable support plate 208 will not move and cause the parachute bag to slip when the compression unit compresses the parachute. Furthermore, when it is necessary to release the support of the movable support plate 208 and the fixed support plate 201 for the parachute bag, the movable plate 302 can be driven away from the movable support plate 208 by the electric telescopic part 301. When the movable plate 302 moves, it will drive the traction plate 304 to move through the connecting frame 303. The traction plate 304 can prompt the movable support plate 208 to move together, so that the movable support plate 208 moves closer to the fixed support plate 201, and the support for the parachute bag can be automatically released. It is very convenient to use.

[0034] As an embodiment of the present invention, please refer to Figure 1 and Fig. 9 The lifting unit includes lifting plates 404 which are equidistantly distributed in a ring shape above the disc 104. A vertical tube 401 is fixedly installed on the upper surface of the disc 104. A movable rod 403 is fixedly arranged on the lower surface of the lifting plate 404, and the movable rod 403 is movably arranged in the vertical tube 401. The bottom inner wall of the vertical tube 401 and the bottom end of the movable rod 403 are connected by a second spring 402. The lifting plate 404 can lift the parachute bag. When the compression unit compresses the parachute in the parachute bag, the parachute bag will also be straightened, and the lifting plate 404 will move adaptively with the parachute bag, prompting the movable rod 403 to move downward to compress the second spring 402 in the vertical tube 401, thereby avoiding affecting the compression of the parachute and achieving better use effect.

[0035] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8The compression unit includes a telescopic cylinder 501. The outer wall of the mounting plate 109 is provided with fixing holes which are equidistantly distributed in an annular shape. The telescopic cylinder 501 is fixedly arranged in the fixing hole. A pressure block 502 is fixedly installed at the telescopic end of the telescopic cylinder 501. The outer wall of the pressure block 502 is provided with through holes which are distributed in a rectangular array. A push rod 503 is movably installed in the through hole. A baffle 504 is fixedly installed on the outer wall of the push rod 503. The baffle 504 is located above the pressure block 502. A pressure plate 505 is fixedly arranged at the bottom end of the push rod 503. The lower surface of the pressure block 502 is provided with a matching groove 511 that matches with the pressure plate 505, and the outer walls on both sides of the pressure block 502 are provided with mounting grooves 510, and a fixed shaft 506 is fixedly installed in the mounting groove 510, and a side pressure plate 508 is rotatably sleeved on the outer side of the fixed shaft 506, and a torsion spring 507 is sleeved on the outer side of the fixed shaft 506, one end of the torsion spring 507 is connected to the side pressure plate 508, and the other end of the torsion spring 507 is connected to the inner wall of the mounting groove 510, and an arc plate 509 is also fixedly installed on the upper surface of the side pressure plate 508. The arc plate 509 is located above the push rod 503, and a pressure measuring component is also provided in the pressure plate 505 for detecting the pressure strength. When the parachute in the parachute bag needs to be compressed, the pressure block 502 can be driven downward by the telescopic cylinder 501 until the pressure block 502 enters the parachute bag. The pressure plate 505 will first contact the surface of the parachute and cause the pressure plate 505 to move upward into the fitting groove 511. The push rod 503 on the upper surface of the pressure plate 505 will simultaneously lift the arc plate 509, causing the side pressure plate 508 to rotate and causing the torsion spring 511 to rotate. 07 is twisted until the pressure plate 505 completely enters the fitting groove 511, at which time the side pressure plate 508 is just in a state parallel to the pressure block 502. The joint pressure of the pressure block 502 and the side pressure plate 508 on the parachute can make the pressure of the parachute more balanced and the compression effect better. When the compression is completed and the telescopic cylinder 501 drives the pressure block 502 to move upward, under the reset action of the torsion spring 507, the side pressure plate 508 rotates and resets again, so that the pressure block 502 can be easily removed from the parachute bag, which is very convenient to use.

[0036] As an embodiment of the present invention, please refer to Figure 6 , Figure 7 and Figure 8The pressure measuring assembly includes a plate groove 601 provided on the lower surface of the pressure plate 505, and a pressure measuring plate 602 is movably provided in the plate groove 601, a movable column 603 penetrating the pressure plate 505 is fixedly provided on the upper surface of the pressure measuring plate 602, and a pressure sensor 604 is fixedly installed on the top of the movable column 603, a stopper 605 is fixedly installed on the outer wall of the movable column 603, and the stopper 605 is located above the pressure measuring plate 602, a fixed frame 606 is also fixedly installed on the upper surface of the pressure measuring plate 602, and the pressure sensor 604 is located in the fixed frame 606, and a groove 607 is also provided on the top inner wall of the fitting groove 511 for accommodating the fixed frame 606, when the pressure plate 505 moves downward, the pressure measuring plate 60 2 will replace the pressure plate 505 to contact the surface of the parachute, prompting the pressure measuring plate 602 to move in the plate slot 601 opened below the pressure plate 505, and prompting the movable column 603 to move upward, so that the pressure sensor 604 between the fixed frame 606 and the movable column 603 is squeezed, and the purpose of detecting the compression force is to apply pressure to the parachute according to the preset pressure increasing speed until the target pressure value is reached. During the entire pressure application process, the pressure sensor 604 continuously monitors the pressure data to ensure that the pressure remains stable. When the pressure reaches the appropriate value, the compression of the parachute can be stopped, avoiding the damage to the material of the parachute caused by over-tight packaging, reducing its service life and performance, and achieving a better use effect.

[0037] As an embodiment of the present invention, please refer to Figure 2 The upper surface of the bracket 101 is also fixedly mounted with brackets 701 that are equidistantly distributed in a ring shape, and the upper surface of the bracket 701 is fixedly mounted with a support sheet 702, which fits the lower surface of the disc 104. The support sheet 702 above the bracket 701 can lift the disc 104, making the disc 104 more stable during rotation and having a better use effect.

[0038] During use, when the parachute is packed, the parachute bag containing the parachute can be placed on the lifting unit with the help of manual labor, and the parachute bag can be opened by the bag-opening unit, and the mounting plate 109 can be driven to rise and fall by the hydraulic cylinder 106, so that the distance between the bag-opening unit and the lifting unit can be conveniently adjusted according to the length of the parachute bag, so that when the bag-opening unit opens the parachute bag, the lifting unit can just lift the parachute bag. At the same time, the servo motor 102 can drive the rotating shaft 103, and the rotating shaft 103 drives the disc 104 to rotate, so that the parachute bag rotates with the disc 104. When the disc 104 rotates, the compression unit can enter the parachute bag, exerting uniform and appropriate pressure on the parachute, thereby compressing the parachute in the parachute bag, and effectively reducing the space occupied by the parachute in the parachute bag, avoiding over-packing of the parachute. The internal structure is easily displaced during transportation or storage, which affects the subsequent normal use. The packaging quality of the parachute is improved, and its reliability and safety during use are guaranteed. When the parachute in the parachute bag is compressed, the compression unit can be removed from the parachute bag and the support of the bag support unit to the parachute bag can be released. At this time, the parachute bag falls to the surface of the lifting unit and continues to rotate with the disc 104. It can be picked up and transferred manually or mechanically. The device effectively realizes the continuous compression packaging of the parachute. Compared with the traditional manual pressing packaging method, it effectively improves the packaging efficiency, can meet the needs of large-scale production, and can ensure that uniform and appropriate pressure is applied to the parachute, avoiding the situation of packaging being too loose or too tight, improving the packaging quality of the parachute, ensuring its reliability and safety during use, and having a better use effect.

[0039] It should be particularly noted that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
