[0041] Specifically, in this embodiment, the bracket is arranged on the main frame 1 through the transmission device 2. After the carrying bale 3 is rotated onto the bracket, it drives the bracket to move downward under its own weight, transfers the potential energy of the carrying bale 3 to the transmission device 2, and exports the potential energy through the transmission device 2 for recovery and conversion for utilization.

[0042] In a preferred embodiment, the transmission device 2 includes a top rotating shaft 5, a bottom rotating shaft, a top sprocket, a bottom sprocket and a transmission chain 7; the top sprocket is arranged on the top rotating shaft 5, the bottom sprocket is arranged on the bottom rotating shaft, and the transmission chain 7 meshes with the top sprocket and the bottom sprocket respectively; a recovery channel 4 is arranged on the main frame 1, the top rotating shaft 5 and the bottom rotating shaft are respectively arranged at the upper and lower ends of the recovery channel 4, and the axes of the top rotating shaft 5 and the bottom rotating shaft are in the same vertical plane.

[0043] In this embodiment, a recovery channel 4 is arranged on the main frame 1, and the carrying bale 3 descends and is recovered by its own weight in the recovery channel.

[0044] Specifically, in this embodiment, as Figure 2 shown, there are two channels on the main frame 1. One on the left is a pressurization channel where the carrying bale rises, and the one on the right is the recovery channel 4 where the carrying bale descends. The transmission device 2 is arranged on the recovery channel 4 and can recover and convert the potential energy when the carrying bale 3 descends.

[0045] More specifically, in this embodiment, the top rotating shaft 5 and the bottom rotating shaft of the transmission device 2 are respectively arranged at the upper and lower ends of the recovery channel 4, a top sprocket is arranged on the top rotating shaft 5, a bottom sprocket is arranged on the bottom rotating shaft, and they are connected by a transmission chain 7 between the top sprocket and the bottom sprocket to form an annular transmission loop. At this time, the horizontal supporting claws 13 are arranged on the transmission chain 7. The carrying bale 3 is rotated onto the horizontal supporting claws 13, drives the horizontal supporting claws 13 to move downward by gravity and then drives the transmission chain 7 to drive, so that the carrying bale 3 falls smoothly, and the potential energy is recovered or converted to achieve reuse.

[0046] It should be noted that, in this embodiment, the transmission device 2 is a chain drive, and it can also be other transmission methods, such as belt drive, etc. That is to say, as long as the carrying bale 3 can fall smoothly through the transmission device 2, and the potential energy can be recovered or converted to achieve reuse.

[0047] In this embodiment, the axes of the top rotating shaft 5 and the bottom rotating shaft are in the same vertical plane, which can make the specifications of the top sprocket and the bottom sprocket the same and ensure the smoothness when the bearing compression package 3 drops.

[0048] In a preferred embodiment, the bracket includes a vertical arm 12 and a horizontal supporting claw 13; the vertical arm is hinged to the transmission chain 7, and the horizontal supporting claw 13 is arranged on the vertical arm, and the horizontal supporting claw 13 is used to support the bearing compression package 3.

[0049] Specifically, in this embodiment, the vertical arm 12 of the bracket is attached to the outer side of the loop of the transmission chain 7, and the horizontal supporting claw 13 is arranged on the side of the vertical arm 12 away from the transmission chain 7. Among them, the upper surface of the horizontal supporting claw 13 is horizontally arranged and is used to abut against the lower side surface of the bearing compression package 3 to play a bearing role on the bearing compression package 3.

[0050] In a preferred embodiment, as Figure 3 and Figure 4 shown, a U-shaped chain track 8 is further arranged on the main frame 1, an inner cavity 9 is arranged on the U-shaped chain track 8, and the transmission chain 7 is arranged in the inner cavity 9.

[0051] Such a setting method makes the lateral stiffness relied on by the transmission chain 7 mainly provided by the U-shaped chain track 8 to ensure that when the bearing compression package 3 drops, the horizontal supporting claw 13 has sufficient position stability.

[0052] In a preferred embodiment, inner pressure wheels 10 are arranged on both sides of the upper end of the vertical arm 12, the two inner pressure wheels 10 are connected by a pin shaft 11, and the pin shaft 11 passes through the transmission chain 7; the number of the inner cavities 9 is two, the two inner cavities 9 are respectively arranged on the opposite sides of the transmission chain 7, and the two inner pressure wheels 10 are respectively arranged in the two inner cavities 9, and the wheel walls of the inner pressure wheels 10 abut against the inner walls of the corresponding inner cavities 9; outer pressure wheels 14 are arranged on both sides of the lower end of the vertical arm 12, and the wheel walls of the two outer pressure wheels 14 respectively abut against the outer walls of the two corresponding inner cavities 9.

[0053] In this embodiment, when the bearing compression package 3 falls onto the horizontal supporting claw 13, the flexible transmission chain 7 only bears the vertical load. Relying on the stiffness of the U-shaped chain track 8, a pair of force couples generated by the inner pressure wheels 10 and the outer pressure wheels 14 abutting against the inner and outer walls of the inner cavity 9 are used to ensure the stability of the horizontal supporting position of the horizontal supporting claw 13.

[0054] In a preferred embodiment, a plurality of top sprockets are arranged on the top rotating shaft 5, and bottom sprockets 7 corresponding to the number of the top sprockets are arranged on the bottom rotating shaft, and the number of the transmission chains 7 is set in one-to-one correspondence with the number of the top sprockets and the number of the bottom sprockets.

[0055] Specifically, in this embodiment, two top sprockets are provided on the top rotating shaft 5, and two bottom sprockets are provided on the bottom rotating shaft.

[0056] One top sprocket, one transmission chain 7, and one bottom sprocket can form a set of transmission mechanisms. At least two sets of transmission mechanisms are provided on the top rotating shaft 5, which can ensure the connection balance between the bracket and the bearing bale 3.

[0057] In a preferred embodiment, there are two sets of transmission devices 2, which are symmetrically arranged on opposite sides of the recovery channel 4; a synchronization structure is provided between the two sets of transmission devices 2.

[0058] After the transmission device 2 is provided in two sets, better stability is achieved when the bearing bale 3 is connected to the bracket.

[0059] To ensure the synchronization when the opposite ends of the bearing bale 3 descend, a synchronization structure is provided between the two sets of transmission devices 2. Through the synchronization structure, the two sets of transmission devices 2 can rotate synchronously when rotating.

[0060] Specifically, the transmission method of the synchronization structure is: synchronous transmission is achieved by meshing the bevel gears at both ends of the synchronization shaft with the shaft-end bevel gears of the top rotating shaft.

[0061] In a preferred embodiment, the synchronization structure includes a transmission shaft 6 and two pairs of transmission bevel gears, and is connected to the bevel gears at the shaft ends of the top rotating shaft 5 at one end away from the pressurization channel, forming a "C" shape to achieve synchronous rotation between the two top rotating shafts 5.

In addition, in addition to setting a synchronization shaft with bevel gear pairs at the end of the top rotating shaft, a synchronization shaft with bevel gear pairs can also be set at the end of the bottom rotating shaft at the same time to improve the operation reliability.

[0063] In a preferred embodiment, an energy conversion device is provided on the transmission device 2 for converting the potential energy when the bearing bale 3 descends into hydraulic kinetic energy.

[0064] In this embodiment, the energy conversion device is a speed-up gearbox provided at the end of the bottom rotating shaft, and the output end of the speed-up gearbox is connected to a hydraulic pump. When the bearing bale 3 descends under its own weight, it drives the bottom rotating shaft to rotate. The bottom rotating shaft transmits the rotation to the speed-up gearbox, and the output shaft of the speed-up gearbox drives the connected hydraulic pump. The hydraulic pump can be incorporated into the pressurization system at the bottom of the vertical circulating press to achieve energy recovery and reuse.

[0065] In a second aspect, the present invention also provides an energy-saving circulating cold press, as Figure 1 shown, which includes the vertical recovery system of any one of the above.

[0067] After the load package is transferred from the top end on one side of the pressurization channel to the top end of the recovery channel through the indexing mechanism, it is placed on the horizontal support claws. The four horizontal support claws ensured by the synchronization mechanism support the load package and smoothly descend from a high position to a low position, and drive the hydraulic pump through the speed-up gearbox at the bottom. The kinetic energy of the hydraulic pump is incorporated into the pressurization system at the bottom. Thus, while completing the recovery of the load package, part of the potential energy is recovered and utilized.
