Description

Technical Field

[0001] This utility model relates to the field of wood edge banding technology, specifically a seamless edge banding device. Background Technology

[0002] Fully automatic edge banding machines are widely used in furniture manufacturing, woodworking, and other industries. They are mainly used for edge banding of wood boards and engineered wood products. Through a series of automated devices, the machine applies edge banding tape (usually made of PVC, ABS, etc.) to the edges of the wood boards, completing the edge banding operation. It can automatically feed the boards, apply glue, and then attach the edge banding tape to the edges. It can also automatically pre-mill and start the edges of the boards, and automatically trim and polish the edge banding tape, thus achieving seamless edge banding. However, most existing fully automatic edge banding machines use pressure rollers to press the boards and then use a conveyor to transport them. If the board size is too large, part of the board may be outside the edge banding machine, causing it to be suspended in the air. This can lead to the board's center of gravity not being supported by the machine. When the board reaches the glue application area, the pressure applied to the sides by the glue application rollers can easily cause the board to shift and deviate from the baseline, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a seamless edge sealing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A seamless edge sealing device, comprising:

[0006] The machine body comprises multiple hydraulic cylinders capable of adjusting the height of the abutting mechanism, an abutting mechanism capable of stabilizing the wooden board on the machine body, and two positioning mechanisms.

The abutting mechanism includes a U-shaped frame, and the movable ends of the multiple hydraulic cylinders are respectively fixedly connected to the two arms of the U-shaped frame. A frame is provided between the two arms of the U-shaped frame, and multiple abutting rollers are rotatably connected between the two opposite inner sidewalls of the frame. The two positioning mechanisms are respectively fixedly connected to the opposite sides of the frame.

[0007] Furthermore, a U-shaped plate is fixedly connected to one side of the frame, and multiple electric push rods are fixedly connected to the inner wall of the U-shaped frame, with the movable end of any electric push rod being fixedly connected to the U-shaped plate.

Detailed Implementation

[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 1-4 In this embodiment of the utility model, a seamless edge sealing device includes:

[0023] The machine body 100 includes multiple hydraulic cylinders 200 that can adjust the height of the abutment mechanism 300, the abutment mechanism 300 that can stabilize the wooden board on the machine body 100, and two positioning mechanisms 400. The multiple hydraulic cylinders 200 are all located on one side of the machine body 100. The abutment mechanism 300 is fixedly connected to the movable ends of the multiple hydraulic cylinders 200. The abutment mechanism 300 includes a U-shaped frame 310, and the movable ends of the multiple hydraulic cylinders 200 are respectively fixedly connected to the two arms of the U-shaped frame 310. A frame 330 is provided between the two arms of the U-shaped frame 310, and multiple abutment rollers 331 are rotatably connected between the two opposite inner sidewalls of the frame 330. The two positioning mechanisms 400 are respectively fixedly connected to the opposite sides of the frame 330.

[0024] Specifically, the machine body 100 is a fully automatic edge banding machine. Multiple hydraulic cylinders 200 are arranged on one side of the machine body 100. Then, the height of the U-shaped frame 310 is adjusted by activating the multiple hydraulic cylinders 200. Then, the wooden board is placed on the machine body 100, and the machine body 100 drives the wooden board to move. Then, by moving the frame 330, multiple abutting rollers 331 on the frame 330 abut the wooden board. If the size of the wooden board is large, the edge of the suspended part of the wooden board can be abutted by the abutting rollers 331 on the frame 330. When the wooden board is driven by the machine body 100, it can move on the abutting rollers 331. The suspended part of the wooden board can be stabilized by the edge being abutted by multiple abutting rollers 331 at the same time, reducing the skew of the wooden board during the movement process and improving the stability of the wooden board when it is driven by the machine body 100, thereby reducing the deviation of the wooden board when it is driven by the machine body 100.

[0025] Example 1

[0026] like Figure 1-3As shown, in this embodiment, a U-shaped plate is fixedly connected to one side of the frame 330, and a plurality of electric push rods 320 are fixedly connected to one inner wall of the U-shaped frame 310. The movable end of any electric push rod 320 is fixedly connected to the U-shaped plate.

[0027] In this embodiment, by activating multiple electric push rods 320, the frame 330 can be moved so that the roller 331 on the frame 330 contacts the edge of the suspended part of the wooden board. The opening and closing of multiple electric push rods 320 can be controlled synchronously by a multi-controller to improve the degree of automation and make it easier for users to use. The multi-controller is existing technology and will not be described in detail here.

[0028] like Figure 3-4 As shown, in this embodiment, the positioning mechanism 400 includes:

[0029] The slide rail 410, multiple L-shaped slide rods 420, and multiple cylinders 430 are provided. One side of the slide rail 410 is fixedly connected to the side wall of the adjacent frame 330. One end of the short arm of each of the multiple L-shaped slide rods 420 is slidably engaged inside the slide rail 410. One end of the long arm of each L-shaped slide rod 420 is provided with a sleeve hole. Each of the multiple cylinders 430 corresponds to one of the multiple L-shaped slide rods 420. Each cylinder 430 is fixedly engaged inside the corresponding sleeve hole. The movable end of each cylinder 430 is fixedly connected to a pressure plate 431. Each pressure plate 431 is made of rubber.

[0030] In practical implementation, when the wooden board is placed on the machine body 100, multiple L-shaped slide bars 420 can be moved to move the cylinders 430 to the suspended part of the wooden board. After the edge of the suspended part of the wooden board contacts the abutment roller 331, multiple cylinders 430 can be activated to drive the pressure plate 431 to press down on the opposite sides of the suspended part of the wooden board. This allows the pressure plate 431 to clamp the suspended part of the wooden board from the top and bottom sides, thereby improving the fixing effect of the wooden board and further improving the stability of the wooden board when it moves. Then, when the wooden board moves, multiple L-shaped slide bars 420 can move synchronously on the adjacent slide rails 410 and move synchronously with the wooden board. The rubber pressure plate 431 increases the contact area and friction between the cylinders 430 and the wooden board. In addition, a multi-controller can be added to synchronously control multiple cylinders 430 on two slide rails 410 to open and close synchronously, so that the moving end of any cylinder 430 can extend and retract synchronously, which is convenient for users.

[0031] Example 2

[0032] Based on Embodiment 1, by setting guide wheels 440, annular rope loops 441 and servo motors, it is easy to reset multiple L-shaped slide bars 420, thereby making it easier for users to operate.

[0033] like Figure 3-4As shown, in this embodiment, each slide rail 410 has a U-shaped block fixedly connected to both ends, and a guide wheel 440 is rotatably connected between the two arms of each U-shaped block. An annular rope sleeve 441 is rotatably sleeved between the outer walls of the two guide wheels 440 at both ends of each slide rail 410. Each L-shaped slide rod 420 has a circular hole at one end of its short arm. Each annular rope sleeve 441 is fixedly sleeved with multiple adjacent circular holes. Each slide rail 410 has a motor box 442 fixedly connected to one end. Each motor box 442 has a servo motor installed inside. The motor shaft of each servo motor is fixedly connected to the axle of the adjacent guide wheel 440.

[0034] In practice, after the cylinder 430 on the L-shaped slide bar 420 clamps the wooden board and moves with it, when the wooden board is detached from the machine body 100, the servo motor can be started to drive the adjacent guide wheel 440 to rotate. This causes the guide wheel 440 to drive the annular rope sleeve 441 to rotate, causing multiple adjacent L-shaped slide bars 420 to be reset by the rotating annular rope sleeve 441. This makes it easier for the cylinder 430 on the L-shaped slide bar 420 to clamp the newly entered wooden board into the machine body 100, thus facilitating the use by the user. The motor shaft of the servo motor can rotate freely when the servo motor is not started.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and 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.
