[0003] Existing compression mechanisms typically perform unidirectional compression, resulting in a long compression distance and consequently low compression efficiency, causing inconvenience for users. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0028] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a compression mechanism for packaging memory foam, including a support base 1, a protective block 2 connected to the top of the support base 1, a hydraulic cylinder 3 connected to the top of the protective block 2, a movable top plate 4 connected to the bottom of the piston rod of the hydraulic cylinder 3, and a movable bottom plate 5 symmetrically distributed with the movable top plate 4 inside the protective block 2. Two guide rods 6 are symmetrically connected to both ends of the movable top plate 4 and the movable bottom plate 5. Two guide rods 6, which are far apart from each other, are connected to two mirror-distributed movable racks 7. Two movable racks 7, which are close together, are connected to a cylindrical gear 8. This facilitates the sliding of one movable rack 7 when the hydraulic cylinder 3 drives the movable top plate 4 to descend. The movable rack 7 then drives the cylindrical gear 8 to rotate, causing the other movable rack 7 to slide in the opposite direction. This, in turn, causes the other movable rack 7 to drive the movable bottom plate 5 to rise. Thus, the opposing sliding of the movable top plate 4 and the movable bottom plate 5 reduces the compression process and improves the compression efficiency.

[0030] In this embodiment, guide grooves 11 are provided on the outer walls of both ends of the protective block 2. The guide rod 6 is connected to the protective block 2 through the guide grooves 11, which facilitates the guidance of the movable top plate 4 and the movable bottom plate 5 when they slide, thereby improving the stability of the movable top plate 4 and the movable bottom plate 5 when they slide.

[0031] Furthermore, the outer wall of the guide rod 6 is rotatably connected to a movable wheel 12, and the guide rod 6 is slidably connected to the guide groove 11 through the movable wheel 12, which helps to reduce friction when the guide rod 6 slides and effectively extends its service life.

[0032] Based on the above embodiments, this embodiment further illustrates that a pushing mechanism 13 is provided at one side opening of the protective block 2. The pushing mechanism 13 includes a support plate 1301. A fixing rod 1302 is fixedly connected to the inner wall of the support plate 1301. Two return springs 1303 are respectively connected to both sides of the fixing rod 1302. The ends of the two return springs 1303 on each side that are far apart from each other are connected to movable push plates 1304. This facilitates the sliding of the two movable push plates 1304 inside the support plate 1301 after the movable top plate 4 and the movable bottom plate 5 slide towards each other. Through the elasticity of the return springs 1303, the two movable push plates 1304 can be reset and slid after the movable top plate 4 and the movable bottom plate 5 slide away from each other.

[0033] Regarding how to drive the movable push plate 1304 and the support plate 1301 to slide, this embodiment further explains that a slider 1305 is connected to one end of the movable push plate 1304 that is far apart from each other. A lead screw 1306 is threadedly connected to the inner wall of the slider 1305. The lead screw 1306 is rotatably connected to a groove opened on one side of the movable top plate 4 and the movable bottom plate 5 that are close to each other through a bearing. Specifically, the movable push plate 1304 and the support plate 1301 are respectively perpendicular to the movable top plate 4 and the movable bottom plate 5, which facilitates the slider 1305 to slide after the lead screw 1306 rotates, so that the slider 1305 drives the movable push plate 1304 and the support plate 1301 to slide and then horizontally compresses the memory foam.

[0034] Regarding how to drive the lead screw 1306 to rotate, this embodiment further explains that one end of the lead screw 1306 is connected to a driven gear 1307, and the outer wall of the driven gear 1307 is connected to a fixed rack 1308. The fixed rack 1308 is fixed to the outer wall of the opening on one side of the protective block 2, thereby facilitating the sliding of the movable top plate 4 and the movable bottom plate 5. The driven gear 1307 is driven to slide by the lead screw 1306, so that the driven gear 1307 rotates by meshing with the fixed rack 1308. Thus, without the need for additional energy to drive, the horizontal compression function is effectively achieved, reducing energy consumption and improving the convenience of operation.

[0035] Regarding how to ensure the horizontal compression rate, this embodiment further explains that a sealing door 9 is movably connected to the opening on the other side of the protective block 2 via a hinge. A limit block 10 is connected to the inner wall of the sealing door 9, which facilitates the limit block 10 to be parallel to the movable push plate 1304 and the support plate 1301 after the sealing door 9 is closed. This facilitates the limitation of one end of the memory foam during horizontal compression, ensuring the compression work and preventing slippage during compression, which could lead to compression failure.

[0036] In use, the memory foam is first placed inside the protective block 2, between the movable top plate 4 and the movable bottom plate 5. Then, the sealing door 9 is rotated and closed by the hinge. Next, the hydraulic cylinder 3 is activated, causing the movable top plate 4 to descend. The movable top plate 4 then slides a movable rack 7 via the guide rod 6. This movable rack 7 drives the cylindrical gear 8 to rotate, causing the cylindrical gear 8 to drive another movable rack 7 to slide in the opposite direction. This causes the other movable rack 7 to drive the movable bottom plate 5 and the movable top plate 4 to slide in opposite directions, compressing the memory foam. This effectively reduces the compression process of the memory foam and thus improves the compression efficiency.

[0037] At the same time, when the movable top plate 4 and the movable bottom plate 5 slide towards each other, they respectively drive the two sets of lead screws 1306 to slide, which in turn drive the two sets of driven gears 1307 to slide. The two sets of driven gears 1307 rotate through meshing with the fixed rack 1308, which in turn drives the lead screws 1306 to rotate. The lead screws 1306 drive the slider 1305 to slide horizontally through the thread, which in turn drives the movable push plate 1304 to slide horizontally. As a result, after the movable push plate 1304 drives the support plate 1301 to slide horizontally, it performs horizontal compression work on the memory foam, which helps to improve the compression rate of the memory foam and further reduces the space occupied by the memory foam.

[0038] At the same time, when the movable top plate 4 and the movable bottom plate 5 slide towards each other, they will drive the two movable push plates 1304 to slide towards each other, so that the two movable push plates 1304 drive the two sets of return springs 1303 to squeeze, thereby ensuring that horizontal compression can be carried out simultaneously during the longitudinal compression of the memory foam.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
