[0003] The polyurethane foam coil is first smoothly conveyed to the feed port of the continuous compression equipment through a conveying device. After entering the equipment, the coil is firstly squeezed by a preliminary compression mechanism to reduce the thickness and volume. Then, the coil after preliminary compression enters the main compression area, where a more powerful compression mechanism is used to further reduce its volume and increase its density. The compressed coil needs to be cooled and shaped to maintain the stability of its shape and size. The cooled and shaped polyurethane foam coil is conveyed out of the equipment through the discharge port and can then enter the next process or be packaged and stored;

The bracket 42 is fixedly connected to the top of the fixing block 43 . The bracket 42 is located at the bottom of the screw rod 41 .

[0032] The above scheme is adopted: the fixed frame 1 is used as the main frame of the whole equipment, providing the installation and support basis for other mechanisms, ensuring that the various components maintain a relatively stable position relationship during operation, ensuring the overall structural stability and reliability of the equipment, and through the setting of the roller pressing mechanism 2, a double-row staggered roller pressing is adopted, which has small working resistance and stable pressing action. The reduction motor A31 is turned on, and its output end drives the transmission rod to rotate, thereby rotating the gear 32, and the gear 32 is meshed with the rack 33, driving the rack 33 and the top plate 21 connected thereto to start moving. As the top plate 21 moves, the linear guide rod 22 slides on the linear guide rail 23 to ensure the linearity of the top plate 21. The bottom plate 24 on the bottom of the linear guide rail 23 and the compacting rods 25 staggered at the bottom of the top plate 21 and the bottom plate 24 also move accordingly.

The driving mechanism 3 includes a reduction motor A31, a gear 32 and a rack 33. The output end of the reduction motor A31 is splined with a transmission rod, one end of the transmission rod passes through the middle of the fixed frame 1 and is fixedly connected to the gear 32, and the gear 32 and the rack 33 are meshingly connected. The reduction motor A31 is fixedly installed in the middle of the fixed frame 1, one side of the rack 33 is meshingly connected to the gear 32, and the other side of the rack 33 is connected to the top plate 21.

[0034] The above scheme is adopted: the linear guide rod 22 cooperates with the linear guide rail 23 to ensure that the top plate 21 maintains a linear motion trajectory during movement, prevents deviation or shaking, and ensures the accuracy and stability of the pressing process. The linear guide rail 23 provides a guiding function for the linear guide rod 22, so that the linear guide rod 22 can slide smoothly, reduce friction resistance, and improve movement efficiency.

[0035] like Figures 1 to 6As shown, a reduction motor B5 is fixedly installed at one end of the fixed frame 1, and a transmission rod is splined at the output end of the reduction motor B5. One end of the transmission rod is fixedly connected to two active sprockets 51, and the surfaces of the two active sprockets 51 are meshedly connected to active chains 52. There are two active chains 52, and the insides of the two active chains 52 are meshedly connected to A sprockets 53. The top of the A sprocket 53 is fixedly connected to the B sprocket 55 through the A rod 54, and the surface of the B sprocket 55 is meshedly connected to the B chain 56. The inside of the B chain 56 is meshedly connected to the C sprocket 57. The bottom of the C sprocket 57 is fixedly connected to the D sprocket 59 through the C rod 58. The surface of the D sprocket 59 is meshedly connected to the D chain 591. The inside of the D chain 591 The E sprocket 592 is meshedly connected to the E sprocket 592, and the E rod 593 is fixedly connected to the inside of the E sprocket 592. There are two groups of screw rods 41, brackets 42 and fixed blocks 43, and the number of each group is three. The two groups of screw rods 41, brackets 42 and fixed blocks 43 are all located on the surfaces of both sides of the fixed frame 1. The outer rings at the bottom ends of the two groups of screw rods 41 are rotatably connected to the top of the brackets 42 through bearings, one end of two screw rods 41 passes through the two brackets 42 and is respectively connected to the two fixed blocks 43, one end of the other two screw rods 41 passes through two of the brackets 42 and is respectively connected to two of the fixed blocks 43, and one end of the last two screw rods 41 passes through the last two brackets 42 and is respectively connected to the last two fixed blocks 43

[0036] By adopting the above solution, the bottom plate 24 is connected to the compacting rod 25 to provide bottom support for the compacting rod 25 , and at the same time, driven by the linear guide rail 23 , it moves in coordination with the top plate 21 to achieve uniform pressure on the material.

[0037] Working principle and use process of the present invention: Check whether all parts of the equipment are firmly installed, whether the protrusions and grooves of the linear guide rod 22 and the linear guide rail 23 are well matched, whether the compaction rod 25 rotates flexibly, whether the gear 32 and the rack 33 are meshed normally, whether the connection between each chain and sprocket is stable, and confirm that the reduction motor A31, the reduction motor B5 and the screw rod 41 of each adjustment mechanism 4 are in the initial state;

[0038] Turn on the reduction motor A31, and its output end drives the transmission rod to rotate, thereby rotating the gear 32, and the gear 32 meshes with the rack 33, driving the rack 33 and the top plate 21 connected thereto to start moving. At the same time, turn on the reduction motor B5, and the output end drives the transmission rod to rotate, and the two active sprockets 51 on the transmission rod drive the A sprocket 53 to rotate through the active chain 52, and the A sprocket 53 drives the B sprocket 55 to rotate through the A rod 54, and the B chain 56 on the B sprocket 55 drives the C sprocket 57 to rotate, and the C sprocket 57 drives the D sprocket 59 to rotate through the C rod 58, and the D chain 591 on the D sprocket 59 drives the E sprocket 592 to rotate, thereby realizing the operation of the entire transmission system;

[0039] As the top plate 21 moves, the linear guide rod 22 slides on the linear guide rail 23 to ensure the linearity of the top plate 21. The bottom plate 24 on the bottom of the linear guide rail 23 and the compacting rods 25 staggered at the bottom of the top plate 21 and the bottom plate 24 also move accordingly. When the compacting rods 25 contact the object to be compacted (such as a polyurethane foam coil), the compacting operation begins. Since there are several groups of compacting rods 25 and they are staggered, a relatively uniform compacting effect can be achieved.

[0040] According to the actual pressing requirements, the adjustment can be made through the adjusting mechanism 4, and the driven sprocket rotates the screw rod 41. Since one end of the screw rod 41 is connected to the fixed block 43, and the other end is rotatably connected to the bracket 42, and the bracket 42 is fixed on the top of the fixed block 43, when the screw rod 41 rotates, the position of the fixed block 43 and the fixed frame 1 connected thereto will change, thereby adjusting the height of the top plate 21 and the bottom plate 24 and the pressure of the compacting rod 25, so as to achieve precise control of the degree of pressing;

[0041] After completing the pressing task, first turn off the reduction motor B5 to stop the operation of the transmission system, then turn off the reduction motor A31 to stop the movement of the top plate 21, the compacting rod 25 and other components, check and maintain the equipment, and prepare for the next use.
