Flattening device for door plate machining

Abstract

The utility model relates to the technical field of wood processing, and discloses a flattening device for door plate processing, which comprises a pressing platform, a support frame is arranged at the bottom of the pressing platform, and a support side frame is arranged at the top of the pressing platform. According to the flattening device for door plank machining, when a plate is flattened through the pressing device, the center position of the plate is pressed through the pressing disc, then the plate is gradually pressed from inside to outside through the pressing rings on the outer side, and therefore in the process that the plate is pressed to be straight and extends, the plate cannot be damaged. According to the plate flattening device, due to the fact that the outer edge is pressed and cannot extend outwards, the plate flattening quality is improved, rubber gaskets are arranged at the bottoms of the pressing disc and the pressing ring, when the pressed position of the plate is extended, the rubber gaskets compensate extension displacement through deformation, and the plate flattening quality is improved. Therefore, the plank is prevented from being unfolded insufficiently to influence the flattening effect in the flattening process.

Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a flattening device for door panel processing. Background Technology

[0002] Timber processing belongs to the forestry industry system and is an important link in the comprehensive utilization of timber resources. Together with forest chemical processing, it constitutes the downstream industry of forest harvesting and transportation. The timber processing industry has formed a complete industrial chain, with products covering traditional fields such as building components, furniture, and packaging containers, and extending to the utilization of renewable resources such as artificial boards. When using timber to process door panels, in order to maintain the straightness of the door panels, it is usually necessary to flatten the wood boards to make the surface of the wood boards flatter, thereby improving the quality of the door panels. However, when general flattening equipment is used, it only uses two planes to flatten simultaneously. As the wood boards are unfolded and straightened, their ends will extend outward under pressure, making the boards prone to cracking and affecting the quality of the boards. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a flattening device for door panel processing, which solves the problem that the outer edge of the panel is pressed outward and obstructed during the flattening process, affecting the flattening and forming quality of the panel.

[0005] (II) Technical Solution

[0007] Preferably, the pressing device includes a central mounting cavity, a central pressing spring, a central pressing column, a pressing plate, a circular contraction notch, an outer mounting cavity, an outer pressing spring, a piston ring, a support ring frame, a pressing ring, and an annular contraction notch. The central mounting cavity is located inside the pressing column near its center. The central pressing spring is disposed inside the central mounting cavity. The top end of the central pressing column is movably engaged inside the central mounting cavity. The bottom end of the central pressing spring contacts the top end of the central pressing column. The bottom end of the central pressing column extends below the pressing column. The pressing plate and... The central pressing post is installed at its bottom end. The circular contraction notch is opened on the bottom surface of the pressing post and located outside the central pressing post. The outer mounting cavity is opened inside the pressing post and located outside the central mounting cavity. The piston ring is movably engaged inside the outer mounting cavity. The outer pressing spring is installed on the top of the piston ring. The support ring frame is installed at the bottom of the piston ring. The bottom end of the support ring frame extends below the pressing post. The pressing ring is installed at the bottom end of the support ring frame. The annular contraction notch is opened at the bottom of the pressing post and located outside the support ring frame.

[0008] Preferably, a support ball is embedded at the top of the pressing platform and at the position outside the pressing column.

[0009] Preferably, there are four support ring frames, with the inner support ring frame being longer than the outer support ring frame, and the bottom plane of the pressing plate being located below the bottom plane of the pressing ring.

[0010] Preferably, the depth of the circular contraction notch is equal to the thickness of the pressing plate, and the depth of the annular contraction notch is equal to the thickness of the pressing ring.

[0011] Preferably, the bottom of both the pressing plate and the pressing ring is covered with a layer of rubber pads for buffering and compensating for horizontal displacement.

[0012] Compared with the prior art, this utility model provides a flattening device for door panel processing, which has the following features:

[0013] Beneficial effects:

[0014] 1. The door panel processing flattening device first presses the center of the panel with the pressing plate, and then the outer pressing rings press the panel from the inside to the outside. This does not affect the panel's ability to flatten outwards due to being pressed along the outer edge, thus improving the quality of the panel flattening.

[0015] 2. The door panel processing flattening device uses rubber pads at the bottom of the pressing plate and pressing ring. When the board is pressed and the position is stretched, the rubber pads compensate for the stretching displacement by deformation, thereby preventing the board from being insufficiently stretched during the flattening process and affecting the flattening effect.

[0016] 3. The pressing device for door panel processing reduces frictional resistance when moving wood on the pressing platform by supporting the wood with ball bearings, making it easier to move. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a flattening device for door panel processing, including a pressing platform 1, a support frame 2 installed at the bottom of the pressing platform 1, a support side frame 3 installed at the top of the pressing platform 1, a mounting top plate 4 installed at the top of the support side frame 3, a hydraulic telescopic column 5 installed at the top of the mounting top plate 4, the output end of the hydraulic telescopic column 5 passing through the mounting top plate 4 and extending to the bottom of the mounting top plate 4, a pressing column 6 installed at the output end of the hydraulic telescopic column 5, and a pressing device 7 with a flattening function from the inside out provided at the bottom of the pressing column 6.

[0023] Furthermore, the pressing device 7 includes a central mounting cavity 71, a central pressing spring 72, a central pressing column 73, a pressing plate 74, a circular contraction notch 75, an outer mounting cavity 76, an outer pressing spring 77, a piston ring 78, a support ring frame 79, a pressing ring 80, and an annular contraction notch 81. The central mounting cavity 71 is located inside the pressing column 6 near the center. The central pressing spring 72 is located inside the central mounting cavity 71. The top end of the central pressing column 73 is movably engaged inside the central mounting cavity 71. The bottom end of the central pressing spring 72 contacts the top end of the central pressing column 73. The bottom end of the central pressing column 73 extends below the pressing column 6. The pressing plate 74 is installed with the bottom end of the central pressing column 73. The circular contraction notch 75... 5 is located on the bottom surface of the pressing post 6 and outside the central pressing post 73. The outer mounting cavity 76 is located inside the pressing post 6 and outside the central mounting cavity 71. The piston ring 78 is movably engaged inside the outer mounting cavity 76. The outer pressing spring 77 is installed on the top of the piston ring 78. The support ring frame 79 is installed at the bottom of the piston ring 78. The bottom end of the support ring frame 79 extends below the pressing post 6. The pressing ring 80 is installed at the bottom end of the support ring frame 79. The annular contraction notch 81 is located at the bottom of the pressing post 6 and outside the support ring frame 79. The pressing device 7 gradually presses the wooden board from the middle to the outer side, so that the wooden board can be fully extended and flattened, improving the flattening effect.

[0024] Furthermore, a support ball bearing 9 is embedded on the top of the pressing platform 1 and on the outside of the pressing column 6. When moving wood above the pressing platform 1, the frictional resistance of the wood is reduced by the support ball bearing 9, making it easier to move.

[0025] Furthermore, there are four support ring frames 79 in total. The length of the inner support ring frame 79 is greater than that of the outer support ring frame 79. The bottom plane of the pressing plate 74 is located below the bottom plane of the pressing ring 80, so that when the pressing column 6 moves down to perform the pressing work, the template is pressed layer by layer from the inner side to the outer side.

[0026] Furthermore, the depth of the circular shrinkage notch 75 is equal to the thickness of the pressing plate 74, and the depth of the annular shrinkage notch 81 is equal to the thickness of the pressing ring 80. After the pressing column 6 moves to fit against the surface of the board, the pressing plate 74 retracts into the circular shrinkage notch 75, and the pressing ring 80 retracts into the annular shrinkage notch 81, so that the bottom of the pressing column 6, the bottom of the pressing plate 74, and the bottom of the pressing ring 80 form a complete pressing surface to flatten the board.

[0027] Furthermore, a layer of rubber pads for buffering and compensating for horizontal displacement is laid at the bottom of both the pressing plate 74 and the pressing ring 80. When the board is pressed and the position is stretched, the rubber pads compensate for the stretching displacement by deformation, reducing the hard frictional resistance between the board and the pressing surface, thereby preventing the board from being insufficiently unfolded during the flattening process and affecting the flattening effect.

[0028] In use, the sheet material to be flattened is placed on top of the pressing platform 1 and positioned directly below the pressing column 6 that pushes the sheet material to move. As the sheet material is pushed from the outside towards the center of the pressing platform 1, it moves under the support of the supporting balls 9, reducing frictional resistance during movement. After the sheet material is pushed to the desired position, the hydraulic telescopic column 5 is extended, pushing the pressing column 6 downward. The pressing column 6 drives the pressing device 7 downward to flatten the sheet material. During the downward movement, the pressing plate 74 first contacts the surface of the sheet material. As the downward movement continues, the central pressing spring 72 applies a downward pressure to the central pressing column 73 and the pressing plate 74, flattening the center of the sheet material first. Then, the outer pressing ring 80 gradually presses the surface of the sheet material from the inner side to the outer side, causing the sheet material to gradually extend and flatten from the center outward until the bottom of the pressing column 6 is in contact with the surface of the sheet material. The pressing column 6, the pressing plate 74, and the multiple pressing rings 80 work together to flatten the surface of the sheet material.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
