Description

Technical Field

[0001] This application belongs to the field of sheet metal processing equipment, and more specifically, relates to a device for quickly changing the thickness gauge of a hot press. Background Technology

[0002] During the hot pressing process of wood panels, both sides of the panel to be hot-pressed need to be placed to compress the wood to the required thickness and maintain reasonable pressure to achieve the desired hot pressing shape. For example, Chinese patent publication number CN108673689A discloses a method for preparing unilateral surface compressed wood and its preparation, as well as a method for using a thickness gauge and a method for forming the panel.

[0003] Regarding the application of thickness gauges in hot presses, see Chinese Patent Publication No. CN207983630U, which discloses a thickness gauge and a multi-layer hot press. The thickness gauge is elongated and includes a first surface and a second surface arranged opposite to each other. The first surface is in contact with a pressure plate, and the second surface can contact another pressure plate. Both the first surface and the second surface are provided with several through grooves.

[0004] In traditional hot press operations, thickness gauges are often placed manually. This manual placement requires not only moving the gauges manually but also positioning them appropriately within the heat-insulating lining of the press plate to compress the wood to the required thickness and maintain pressure during the hot pressing process. This manual operation demands significant physical exertion from the operators, is inefficient, and improper placement can negatively impact the quality of the subsequent hot pressing.

[0027] The structure and connection method of the remaining parts are the same as those described in the foregoing embodiments. Those skilled in the art can understand and apply the structure described in this embodiment based on their understanding of the foregoing embodiments.

[0028] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0029] In this application, the work platform 1 is welded together from a rod frame and a plate. To ensure the safety of the operator, a platform guardrail 14 is provided at the edge of the work platform 1.

[0030] In this application, the platform lifting chain 2 is used to lift the work platform 1. One end of the platform lifting chain 2 is connected to the vertical lifting guide rod 8 at the corresponding position, and the other end of the platform lifting chain 2 is connected to the work platform 1.

[0031] In this application, the platform lifter 3 can be a hydraulic cylinder or a structure similar to a hydraulic cylinder in the prior art to achieve vertical lifting. The platform lifter 3 has a chain gear assembly 4 rotatably mounted at its telescopic end. The chain gear assembly 4 is connected to a base body via a shaft, and the base body is fixed to the telescopic end of the platform lifter 3. The telescopic end of the platform lifter 3 is connected to the platform lifting chain 2 via the chain gear assembly 4. During the lifting and lowering process of the telescopic end of the platform lifter 3, the chain gear assembly 4 can transmit power to the platform lifting chain 2 through its own tooth structure, thereby realizing the lifting or lowering of the work platform 1 by the platform lifting chain 2.

[0032] In this application, the lifting pulley 5 is disposed on one side of the chain gear assembly 4 and is coaxially disposed with the chain gear assembly 4. The lifting pulley 5 can be connected with the synchronous steel wire rope 6, and the forced synchronization of the platform lifters 3 on both sides of the frame structure can be achieved through the synchronous steel wire rope 6.

[0033] In this application, the vertical lifting guide rod 8 is a structure of multiple vertically parallel rods, each with its top end fixedly connected to the horizontal frame rod 11. The vertical lifting guide rod 8 and the horizontal frame rod 11 form a frame structure. Guide wheel sets 7 are provided at both ends of the horizontal frame rod 11 of the frame structure. Slide guide wheels are provided at the platform slide 9 on the outside of the frame structure. Lifting pulleys 5 are provided at the chain gear assembly 4 on the outside of the frame structure. The two ends of the synchronous steel wire rope 6 are respectively connected to the lifting pulleys 5 on both sides of the frame structure, and form a running path similar to a "Z" shape through the slide guide wheels on the platform slide 9 on both sides of the frame structure and the guide wheel sets 7 at the top of the frame structure. The purpose of the above structure is to achieve forced mechanical synchronization of the piston rods of the platform lifting device 3 on both sides of the frame structure.

[0034] In this application, adjacent platform slides 9 can be connected as one unit via slide synchronization rods 10. The slide synchronization rods 10 achieve forced synchronization of the platform slides 9, thus enabling... Figure 2 The adjacent platform lifters 3 shown are forced to synchronize mechanically, thereby achieving synchronization of all platform lifters 3 and avoiding the problem of asynchronous platform lifters 3 caused by hydraulic control.

[0035] In this application, the conveying power device 12 is a drive motor, which provides power to the conveying chain assembly 16, causing the conveying rack in the conveying chain assembly 16 to move under the drive of the chain gear, thereby realizing the conveying of the thickness gauge.

[0036] In this application, in order to achieve stability in conveying the thickness gauge along the conveyor chain assembly 16, a conveyor limiting plate 13 can be provided on the side of the conveyor chain assembly 16 away from the vertical lifting guide rod 8. The conveyor limiting plate 13 cooperates with a plurality of distributed vertical lifting guide rods 8 to guide and limit the thickness gauge during the conveying process.

[0037] The usage process of this application is as follows: the lifting power device 15 is used to operate several platform lifters 3. The platform lifters 3 start to work, the telescopic end of the platform lifters 3 extends and lifts the work platform 1 through the chain gear assembly 4 and the platform lifting chain 2. The adjacent platform lifters 3 are mechanically synchronized through the sliding seat synchronization rod 10. The platform lifters 3 on both sides of the frame structure formed by the vertical lifting guide rod 8 and the horizontal frame rod 11 are mechanically synchronized through the synchronization steel wire rope 6.

[0038] Under the lifting action of the platform lifter 3, the working platform 1 moves upward along the vertical lifting guide rod 8 to a suitable position via the platform slide 9, aligning the conveyor chain assembly 16 with the hot press plate at that position. The thickness gauge is placed on the conveyor chain assembly 16, and the conveyor power device 12 drives the conveyor chain assembly 16 to move towards the hot press until the thickness gauge moves along the conveyor chain assembly 16 to the top of the hot press plate and is placed on the heat insulation liner of the plate. Repeating the above process can achieve the placement of thickness gauges on several plates in the vertical direction of the hot press. Under the action of the horizontal moving platform, the thickness gauges on the other side of the hot press plate can be placed, and the thickness gauges on several plates in the vertical direction on that side can be placed sequentially.

[0039] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
