The rack 331 is fixedly arranged on the base 120, the driving disc 335 is rotatably arranged on the rack 331, the driving disc 335 is drivingly connected with the driving shaft 312 through a second transmission member, so that the driving shaft 312 drives the driving disc 335 to rotate when the driving shaft 312 rotates, the driving disc 335 drives the driven Geneva wheel 333 to rotate intermittently when the driving disc 335 rotates, the incomplete gear 334 is fixedly connected with the driven Geneva wheel 333 and is used for meshing with the rack 332, the rack 332 is driven to descend when the toothed part of the incomplete gear 334 meshes with the rack 332 and the incomplete gear 334 rotates, the rack 332 drives the support frame 110 to descend, and the descending distance of the support frame 110 each time is the same as the thickness of one polyurethane insulation board, that is, the polyurethane insulation boards falling on the second conveying mechanism 100 are all at the same height regardless of the number of the polyurethane insulation boards, so as to avoid affecting the falling of the next polyurethane insulation board and facilitate the next process to be lifted at one time, thereby saving time. The stacking of one polyurethane insulation board is completed when the toothed part of the incomplete gear 334 is about to be disengaged from the rack 332. Specifically, the number of the polyurethane insulation boards stacked at one time is less than the number of the slots of the driven Geneva wheel 333.

[0032] In the embodiment, the conveying assemblies in the transfer mechanism 300 are multiple, the multiple conveying assemblies are sequentially arranged along the conveying direction of the first conveying mechanism 200, the number of the stacking mechanisms is the same as the number of the transfer mechanisms 300, and each stacking mechanism is correspondingly arranged with one transfer mechanism 300, so as to be applicable to polyurethane insulation boards with larger volume.

[0033] In the embodiment, the energy-saving polyurethane insulation board production device further comprises a driving shaft 340, which drives each first pulley 325 to rotate when rotating to increase the stability of the structure, and the rotation of the driving shaft 340 is driven by the second motor. Specifically, the first motor and the second motor are servo motors, and the start of the first motor and the second motor is controlled by an external control system.

[0034] In the embodiment, the first transmission member and the second transmission member are both transmission belts, and the driving pulley 336 is further fixedly connected to the driving disc 335, and the driving pulley 336 is in transmission connection with the driving shaft 312 through the transmission belt.

[0035] In the embodiment, the support frame 110 comprises a plurality of support columns which are telescopically arranged in the up-down direction, and the support spring is arranged in the support column.

[0036] An energy-saving polyurethane insulation board production process, comprising the steps of uncoiling, guiding, shearing, film pasting, rib pressing, and roller forming; and the steps of steel plate heating, coating, foaming and curing in a laminating machine, sawing, overturning and stacking, and finished product packaging; the overturning and stacking step utilizes the above-mentioned energy-saving polyurethane insulation board production device, which comprises utilizing the first transmission mechanism 200 to transport the polyurethane insulation board processed by the previous process to the transfer mechanism 300, utilizing the transfer mechanism 300 to transfer the polyurethane insulation board transported by the first transmission mechanism 200 to the second transmission mechanism 100, and utilizing the second transmission mechanism 100 to transport the polyurethane insulation board transferred by the transfer mechanism 300 to the next process.

[0037] Specifically, when the transfer mechanism 300 transfers the polyurethane insulation board on the first transmission mechanism 200, the polyurethane insulation board is sent to the corresponding position close to the transfer mechanism 300. The first motor and the second motor are started at the same time to drive the driving shaft 312 and the driving shaft 340 to rotate, respectively. When the driving shaft 340 rotates, each first pulley 325 is driven to rotate by the transmission belt. When the driving shaft 312 rotates, the conveying belt 320 is driven to rotate counterclockwise. When the conveying belt 320 rotates, when the two clamping jaws 322 on one of the fixed plates 321 are in a horizontal state and face the first conveying mechanism, the first motor and the second motor stop working. The first conveying mechanism transports the polyurethane insulation board thereon into the clamping groove 327 on the two clamping jaws 322, and then the first conveying mechanism stops working. The first motor and the second motor are started again to make the conveying belt 320 rotate again, and the polyurethane insulation board on the first transmission mechanism 200 is transmitted to the second conveying mechanism.

[0038] When the polyurethane insulation board reaches the highest point and starts to move downward, the limiting buckle 328 on the corresponding clamping jaw 322 is sleeved on the limiting column 311, so when the conveying belt 320 continues to rotate counterclockwise, it will drive the fixed plate 321 in the interval between the second pulley 326 and the third pulley 329 to move downward and overcome the elastic force of the connecting spring 324 to move closer to the side of the second transmission mechanism 100, pushing the polyurethane insulation board in the clamping slot 327 onto the conveying roller 122 of the second transmission mechanism 100.

[0039] Every time the driving dial 335 rotates one circle, the ratchet gear is driven to descend once, that is, the rack 332 pushes the support frame 110 to descend once, and a distance equal to the thickness of a polyurethane insulation board is left downward, so that the uppermost polyurethane insulation board among the polyurethane insulation boards falling on the second transmission mechanism 100 is at the same height, avoiding affecting the falling of the next polyurethane insulation board, and facilitating the lifting of the next process to be done at one time, saving time. The accumulation of a polyurethane insulation board is completed when the toothed part of the incomplete gear 334 is about to disengage from the rack 332.

[0040] Then the first motor and the second motor are turned off, the conveying belt 320 stops rotating, and the second conveying mechanism is started to move the plurality of polyurethane insulation boards on it at the same time to the next packaging process.

[0041] When the toothed part of the incomplete gear 334 disengages from the rack 332, and the first motor and the second motor are started again, the limiting buckle 328 at the bottom of the limiting column 311 disengages from the limiting column 311, and is ejected away from the conveying belt 320 under the action of the connecting spring 324, the incomplete gear 334 continues to rotate and engages with the rack 332 again to perform the next accumulation work of the polyurethane insulation board.

[0042] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
