For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] like Figures 1 to 10 As shown, the present invention provides a vertical energy-saving circulating cold press machine, including a pressure-holding channel, a bottom pressurizing system, a top pressurizing system, a recovery channel, a top transfer mechanism and a bottom transfer system; the pressure-holding channel is a shaft space where the carrier plate package of the plywood assembly and the pressing package moves vertically upward and maintains pressure; the bottom pressurizing system is arranged at the bottom of the pressure-holding channel, and is used to push the carrier plate package from the bottom transfer system into the pressure-holding channel, and provide bottom pressure guarantee during pressure holding; the top pressurizing system is arranged at the top of the pressure-holding channel, and is used to provide top pressure guarantee for the pressure-holding channel during pressure holding; the recovery channel is the shaft space where the carrier plate package falls back vertically to the ground; the top transfer mechanism is a conveying device that horizontally transfers a group of carrier plate packages at the top of the pressure-holding channel to the top of the recovery channel; the bottom transfer system is located at the bottom of the pressure-holding channel and the recovery channel, supports the carrier plate package, and is used to realize a channel for the carrier plate package to reciprocate between the pressure-holding channel position, the recovery channel position and the assembly station position.

[0051] Specifically, in this embodiment, the pressure-maintaining channel and the recovery channel are both arranged on the main frame 4 , forming a whole through the main frame 4 .

[0052] Specifically, in this embodiment, after the plywood assembly 16 and the press package 15 form the carrier plate press package 1, they are fed to the bottom of the pressure-maintaining channel by the feeding mechanism 2, and under the action of the bottom pressurizing system 3, the carrier plate press package 1 is pushed upward, so that it enters the pressure-maintaining channel and rises in the pressure-maintaining channel.

[0053] When carrier packs 1 are continuously fed into the bottom of the pressure-maintaining channel by the feeding mechanism 2, the carrier packs 1 enter the pressure-maintaining channel under the action of the bottom pressurizing system 3, and all carrier packs 1 are stacked, the carrier packs 1 located above will apply pressure to the carrier packs 1 located below, so that the carrier packs 1 below are pressure-maintained.

[0054] When the pressure-holding channel is fully loaded with carrier packs 1, each time a group of carrier packs 1 enters the pressure-holding channel through the bottom pressurizing system 3, a group of carrier packs 1 will be transferred away from the upper end of the pressure-holding channel through the top transfer mechanism, so that each group of carrier packs 1 has the same residence time in the pressure-holding channel, forming a pressure-holding function with the same pressure.

[0055] In this embodiment, the bottom pressurizing system includes a bottom lifting system and a bottom pressure system; the bottom lifting system is used to quickly lift the carrier plate package directly below the pressure maintaining channel into the pressure maintaining channel; the bottom pressure system is used to ensure the pressure of the carrier plate package entering the pressure maintaining channel during pressure maintenance.

[0056] Specifically, in this embodiment, the power of the bottom pressurizing system 3 is hydraulically driven jacking, which specifically includes a hydraulic cylinder and a jacking platform. The carrier plate press package 1 is moved to the jacking platform under the action of the feeding mechanism 2, and under the action of the hydraulic cylinder, the jacking platform and the carrier plate press package 1 above it are driven to rise.

[0057] In this embodiment, the number of hydraulic cylinders is set to be multiple, and the multiple hydraulic cylinders are arranged in an array to ensure the balance of the jacking platform when it is lifted or lowered.

[0058] In a preferred embodiment, the lower locking mechanism and the upper locking mechanism both include a lock bracket, a lock tongue, an elastic device and a positioning signal electronic control device; the lower locking mechanism and the upper locking mechanism are both arranged in pairs, and the upper locking mechanism and the lower locking mechanism of the same pair are placed on opposite sides of the pressure maintaining channel; the lock bracket is the load-bearing main frame of the upper locking mechanism or the lower locking mechanism; the lock tongue is the part that directly contacts the pressure-bearing belt of the pressure pack and transmits the force to the lock bracket; the elastic device is a single body or a combination of a spring, a lever, a cylinder, and a hydraulic cylinder arranged to ensure the reciprocating movement of the lock tongue approaching or moving away from the carrier plate pressure pack 1; the positioning signal electronic control device is an electric signal carrier that starts to enter the next action only when the lock tongue reaches the corresponding position.

[0059] Specifically, the lower locking mechanism 5 includes a lower locking bracket 11, a lower locking tongue 12 and a lower elastic device 14; the lower locking bracket 11 is arranged on the main frame 4, and a lower locking groove 13 is arranged on the lower locking bracket 11, and the lower locking tongue 12 is embedded in the lower locking groove 13. The lower elastic device 14 connects the lower locking tongue 12 and the lower locking bracket 11, and the lower elastic device 14 is used to apply a force to the lower locking tongue 12 in the direction of the carrier plate pressure package 1; the lower locking mechanism 5 is arranged in pairs on opposite sides of the pressure maintaining channel.

[0060] In this embodiment, the locking of the carrier plate press package 1 by the lower locking mechanism 5 is only used to support the carrier plate press package 1 thereon, and does not hinder the upward movement of the carrier plate press package 1. In other words, the lower locking mechanism 5 is a one-way locking mechanism, and is only in a locked state when the lower locking tongue 12 is in a state of fully extending out of the lower locking groove 13 and supporting the upper load. The purpose of locking is to ensure the reliability of the supporting state.

[0061] More specifically, in this embodiment, the top surface of the lower locking tongue 12 is a plane, and the bottom surface is an inclined surface, so that when the carrier plate press bag 1 moves from bottom to top, it can push the lower inclined surface of the lower locking tongue 12 to retract the locking tongue and allow the carrier plate press bag 1 to pass.

[0062] In a preferred embodiment, a top pressurizing system 9 is provided on the upper part of the pressure-maintaining channel for applying pressure to the carrier plate press bag 1 in the pressure-maintaining channel; an upper locking mechanism 10 is also provided in the pressure-maintaining channel; the upper locking mechanism 10 includes a locking bracket 17, an upper locking tongue 20, a locking structure and an upper elastic device 18; the locking bracket 17 is provided on the main frame 4, and an upper locking groove 19 is provided on the locking bracket 17, and the upper locking tongue 20 is embedded in the upper locking groove 19, and the upper elastic device 18 connects the upper locking tongue 20 and the locking bracket 17, and the upper elastic device 18 is used to apply a force to the upper locking tongue 20 in the direction of the carrier plate press bag 1, and the locking structure is used to lock the upper locking tongue 20 in two states: being completely received in the upper locking groove 19 and being fully extended out of the upper locking groove 19.

[0063] More specifically, the locking of the upper locking tongue 20 when it is completely received in the upper locking groove 19 is to ensure that the upper locking tongue 20 does not block the upward state of the carrier plate pressing package 1; and the locking of the upper locking tongue 20 when it is fully extended out of the upper locking groove 19 is to ensure the reliability of the upper locking tongue 20 when it withstands the upward pressure of the carrier plate pressing package. The upper locking tongue 20 is a structure with a flat bottom surface and an inclined top surface, and is symmetrical with the lower locking tongue 12.

[0064] The upward principle of the carrier plate package in the pressure-maintaining channel is as follows: the carrier plate package 1 running to the bottom of the pressure-maintaining channel is lifted upward by the rapid lifting system of the bottom pressurizing system 3. When the top surface of the assembly plate contacts the bottom surface of the package of the previous group of carrier plate packages, the bottom pressurizing system 3 starts to pressurize, so that all the carrier plate packages in the pressure-maintaining channel move upward synchronously. At this time, the upper locking mechanism 10 is in a non-pressurized state, the upper locking tongue 20 is recovered and locked, and the top pressurizing system 9 maintains pressure and moves upward (the piston rod retracts). When the bottom surface of the bottom package passes over the lower locking tongue 12, the lower locking tongue 12 pops out and locks, and then the bottom pressurizing system 3 stops pressurizing and then the pressure-relieving piston rod retracts, the top pressurizing system 9 maintains pressure, the lower locking tongue 12 supports the upper load, and the system enters a static pressure-maintaining state. After a time interval, the next group of carrier plate press packs 1 are lifted up by the bottom pressurizing system 3. At this time, the upper locking mechanism 10 is turned into the pressure state, and the upper locking tongue 20 pops out and locks, blocking the upward carrier plate press packs and bearing all the pressure in the pressure-maintaining channel. At this time, the bottom pressurizing system 3 is in the pressure-maintaining state, and the piston rod of the top pressurizing system 9 retracts, and the top transfer mechanism is started to transfer the topmost group of carrier plate press packs to the recovery channel. At this point, the upward movement and transfer of a group of carrier plate press packs are completed. This cycle is infinite.

[0065] In a preferred embodiment, the top pressurizing system 9 includes a downward pressure hydraulic cylinder, which applies pressure downward to achieve pressure maintenance of the plywood assembly 16 .

[0066] In this embodiment, the downward pressure hydraulic cylinder is arranged in a one-to-one correspondence with the hydraulic cylinder of the bottom pressurizing system 3 .

[0067] In a preferred embodiment, the hydraulic cylinders of the bottom pressurizing system and the top pressurizing system have equal cylinder diameters and the same number, and a connecting pipe with an electrically controlled locking valve is provided between the bottom pressurizing system and the top pressurizing system; only when the carrier plate pressure bag in the pressure maintaining channel moves upward, the bottom pressurizing system and the top pressurizing system are both under pressure, and the electrically controlled locking valve of the connecting pipe is in an open state.

[0068] In a preferred embodiment, the recovery channel 7 is provided with a transmission device that can ensure that the carrier plate press bag 1 falls smoothly from a high position to a low position by its own weight.

[0069] By setting the transmission device, the carrier plate press bag 1 can be relatively stable during the falling process, and will not fall directly due to gravity acceleration, thereby ensuring the stability of the carrier plate press bag 1 when falling.

[0070] Specifically, in this embodiment, the bottom of the transmission device is connected to a potential energy recovery device 8, and the potential energy recovery device 8 is used to convert the potential energy of the carrier plate pressing package into mechanical energy or hydraulic energy.

[0071] In this embodiment, the potential energy of the carrier plate press package 1 passing through the potential energy recovery channel 7 is recovered by the potential energy recovery device 8, thereby improving the energy utilization rate.

[0072] In a preferred embodiment, the potential energy recovery device 8 is a speed-increasing gearbox, the outlet end of which is connected to a hydraulic pump, which is connected to the bottom jacking system for relay, or the hydraulic pump is the bottom jacking system.

[0073] Such an arrangement enables the potential energy recovered by the energy recovery device 8 to be reused, thereby improving energy utilization.

[0074] Specifically, in this embodiment, the vertical transmission mechanism is arranged on the main frame 4, which can be connected to the carrier plate press bag 1 passing through the potential energy recovery channel 7. When the carrier plate press bag 1 falls, the potential energy of the carrier plate press bag 1 is transmitted to the energy conversion mechanism, and the potential energy is converted into other energy forms through the energy conversion mechanism to facilitate the utilization of the energy.

[0076] In this embodiment, after the top pressurizing system 9 above the pressure-maintaining channel is retracted, the carrier plate press package 1 that has completed the pressure maintenance is transferred to the potential energy recovery channel 7 through the top transfer mechanism 6 to recover the potential energy.

[0077] Specifically, in the present embodiment, the transfer track 21 is arranged on the main frame 4 and is connected above the pressure holding channel and the potential energy recovery channel 7, so that the transfer frame 22 can reciprocate along the transfer track 21 above the pressure holding channel and the potential energy recovery channel 7; an adsorption device 23 is arranged on the transfer frame 22, and the adsorption device 23 can realize the adsorption of the carrier plate press package 1, thereby driving the carrier plate press package 1 to move together with the transfer frame 22.

[0078] When the carrier plate press bale 1 needs to be transferred, the adsorption device 23 first adsorbs the carrier plate press bale 1, and then the transfer rack 22 is started to drive the carrier plate press bale 1 to move from above the pressure holding channel to above the potential energy recovery channel 7, and the adsorption function of the adsorption device 23 is released to separate the carrier plate press bale 1 from the adsorption device 23, and the transfer rack 22 is reset and moved to above the pressure holding channel for the next transfer of the carrier plate press bale 1.

[0079] In this embodiment, the adsorption device 23 is an electromagnetic device, which adsorbs the carrier plate press package 1 through magnetism. At this time, the press package 15 of the carrier plate press package 1 is required to be made of an adsorbable material, such as iron.

[0080] It should be pointed out that the adsorption device 23 can be an electromagnetic device, but it is not limited to an electromagnetic device, and can also be a mechanical hook type device, as long as it can achieve accurate positioning and reliable hanging.

[0081] In this embodiment, the indexing frame 22 moves horizontally by driving the gears connected to the gears of the indexing frame 22 along the track 21 ; the adsorption device 23 moves up and down by driving the worm gear of the motor 24 .

[0082] It should be pointed out that the above is only an ideal implementation method, but is not limited to this method. For example, the track 21 can be a smooth track, and the servo motor fixed at one end of the track 21 drives the worm shaft to achieve horizontal movement, etc. As long as it can achieve efficient operation and accurate positioning.

[0083] In a preferred embodiment, the bottom transfer system includes a conveyor frame, a lifting device 25 and a conversion table; the lifting device 25 is arranged at one end of the conveyor frame close to the blank assembly table, and is used to lift the pressed bales recovered by the conveyor frame to the blank assembly position height; the conversion table is arranged at the upper part of the other end of the conveyor frame, and is used to receive the multilayer plates on the pressed bales; the conveyor frame includes a bracket, a feeding layer and a recovery layer, and the feeding layer and the recovery layer are both arranged on the bracket, and the feeding layer is arranged above the recovery layer; the feeding layer is used to move the pressed bales from one end close to the lifting device 25 to the bottom of the pressure holding channel; the recovery layer is used to move the pressed bales falling from the potential energy recovery channel to the lifting device 25.

[0084] Specifically, in the present embodiment, the conveyor rack is arranged at the lower part of the vertical energy-saving cycle cold press. After receiving the pressed bales after energy recovery, the plywood assembly 16 on the pressed bales is removed through the conversion table. The pressed bales are moved to the top of the lifting device 25 under the action of the conveyor rack. The pressed bales are lifted up by the lifting device 25, and returned to the initial position of receiving the plywood assembly 16, completing the cycle of the pressed bales.

[0085] The vertical energy-saving cycle cold press provided by the present invention pressurizes and recycles the carrier plate package 1 by providing a pressure-maintaining channel and a recovery channel 7, thereby realizing the cold-pressing method for manufacturing plywood, and being able to recycle the high potential energy of the carrier plate package 1.
