Description

Technical Field

[0001] This invention belongs to the technical field of wood board edge banding equipment, and particularly relates to a hot pressing mechanism and a wood board edge banding machine having the same. Background Technology

[0002] A wood panel edge banding machine is a device used to band the exposed edges of engineered wood panels. Currently, wood panel edge banding machines can be divided into automatic edge banding machines and semi-automatic edge banding machines.

[0003] Automatic edge banding machines can automatically convey wood boards, position wood boards, apply glue to edge banding strips, feed edge banding strips to the exposed edges of wood boards, and press edge banding strips and wood boards together to complete the edge banding of wood boards. However, automatic edge banding machines are large in size, generally more than ten meters or even longer, requiring a lot of factory space and are expensive, making them unsuitable for small businesses. Semi-automatic edge banding machines require manual feeding and unloading. After the wood boards are positioned, the edge banding strip is fed to the exposed edge of the wood boards, and then the edge banding strip is pressed to the wood boards by a hot pressing mechanism to complete the edge banding. Although semi-automatic edge banding machines require more manual operation, their overall length can be limited to about three meters, occupying less space, and they are affordable, generally costing one-tenth or even less of the price of automatic edge banding machines, making them very suitable for small businesses. Taking a door panel edge banding machine described in patent document CN221985351U as an example, the existing semi-automatic wood panel edge banding machine structure includes a frame for placing wood panels, a hot press roller for heating and hot pressing the wood panels and edge banding strips, a fixing module for positioning the wood panels on one side of the hot press roller, a translation drive module and a lifting drive module for driving the hot press roller closer to or away from the wood panels. This wood panel edge banding machine completes the hot pressing operation using a long strip of hot press roller with a rectangular cross-section. However, after grooving the surface of the wood panel, the edge of the wood panel has two parallel surfaces and a perpendicular surface connecting these two surfaces, making the edge of the wood panel zigzag-shaped, such as... Figure 1 and Figure 2 As shown, the two mutually perpendicular surfaces obtained by grooving are defined as M1, and the third surface to be edge-banded is defined as M2. When using the existing wood edge banding machine for edge banding, it is necessary to first band the M1 or M2 surface, and then band the other surface. That is, it is necessary to complete the edge banding of one edge of the wood board through two edge banding operations, which results in low edge banding efficiency. Therefore, it is urgent to improve the existing semi-automatic wood edge banding machine to improve the edge banding efficiency of wood boards with grooved edges. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a hot pressing mechanism and a wood board edge banding machine having the same, thereby solving the problem of low edge banding efficiency of existing semi-automatic edge banding machines for grooving wood boards.

[0005] In view of this, the first objective of the present invention is to provide a hot pressing mechanism, comprising: Two hot press rollers are spaced apart in the second direction and have a gap in the first direction so that the two hot press rollers form the same shape as the surface to be sealed. The hot press rollers can heat the surface to the working temperature. The first driving mechanism can simultaneously drive two hot press rollers to move closer to or further away from the surface to be sealed in a first direction.

[0006] In the above technical solution, the hot pressing mechanism further includes a mounting frame, on which both hot pressing rollers are mounted. The mounting frame can reciprocate along a first direction under the drive of the first driving mechanism.

[0007] In the above technical solution, the hot pressing mechanism further includes a translation frame and a second driving mechanism. The translation frame can reciprocate along a first direction under the drive of the first driving mechanism. The second driving mechanism is set on the translation frame and can simultaneously drive two hot pressing rollers to approach or move away from the surface to be sealed in a second direction.

[0008] In the above technical solution, one hot pressing roller is fixed on the mounting frame, and another hot pressing roller is slidably disposed on the mounting frame along the first direction; the hot pressing mechanism also includes a third driving mechanism, which is disposed on the mounting frame, and the hot pressing roller movably connected to the mounting frame can reciprocate along the first direction under the drive of the third driving mechanism.

[0009] In the above technical solution, a mounting groove is further provided in the middle of the hot press roller along the axial direction. The mounting groove extends through at least one end of the hot press roller, and a heating element can be installed in the mounting groove.

[0010] A second objective of the present invention is to provide a wood panel edge banding machine, including the aforementioned hot pressing mechanism, the wood panel edge banding machine further comprising: The frame can support the hot pressing mechanism, and a fourth drive mechanism is installed on the frame; The placement rack is mounted on the frame and located on one side of the hot pressing mechanism. The placement rack can support the wooden board and can be adjusted to a position in the second direction under the drive of the fourth drive mechanism.

[0011] A third objective of this invention is to provide a wood panel edge banding machine, including the aforementioned hot pressing mechanism, the wood panel edge banding machine further comprising: The frame can support the hot pressing mechanism, and the side of the frame located in the first direction of the hot pressing mechanism can support the wooden board; The positioning module is set on the frame and can position the wood board at the processing position on the frame so that the edge to be sealed is aligned with the two hot press rollers.

[0012] In the above technical solution, the positioning module further includes a pusher frame, which can move relative to the frame in a first direction. A pusher block is provided on the pusher frame, and the pusher block extends out of the pusher frame in a second direction. A braking module is provided on the frame, which can lock or release the pusher frame at the current position.

[0013] In the above technical solution, a sliding rod is further provided on the pusher frame, and the sliding rod is slidably connected to the frame in the first direction. The braking module is provided on the frame and includes a brake clamp and a brake cylinder. The brake clamp has an open end and is sleeved outside the sliding rod. The brake cylinder is connected to both sides of the open end of the brake clamp to control the size of the open end of the brake clamp.

[0014] In the above technical solution, a pusher cylinder is further provided on the frame, which can drive the pusher frame to move in the first direction.

[0015] The beneficial effects of this invention are: 1. By setting two hot press rollers to form the same shape as the surface to be sealed and driving them simultaneously, sealing multiple surfaces can be completed in one go, significantly improving sealing efficiency.

[0016] 2. The hot press roller can be adjusted in the second direction through the translation frame and the second drive mechanism, which can adapt to the edge banding requirements of wood boards of different sizes.

[0017] 3. The third drive mechanism enables individual adjustment of a single hot press roller, which can flexibly adapt to wood boards with different grooving depths, further improving the adaptability of the equipment.

[0018] 4. The stability of the wooden board during the edge banding process is ensured by the cooperation of the braking module and the pushing cylinder. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments of the invention. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] The structure M of the wooden board to be edge-sealed in this invention is as follows: Figure 1 As shown, after a groove is cut into one side of the wooden board M, a Z-shaped surface is formed at the edge. Figure 2 The structure of the surface to be sealed is magnified. The surface to be sealed includes two mutually perpendicular surfaces obtained by grooving, which are defined as surface to be sealed M1, and the original surface of the wood board M, which is defined as surface to be sealed M2. In existing technologies, the edges of the wood board M are sealed using only a single rectangular hot-press roller 1. This means that the sealing process can only be performed on the first surface M1 and the second surface M2, requiring two sealing operations to complete the sealing of the wood board M's edges. Therefore, this invention, through an innovative hot-press mechanism design, employs a double hot-press roller 1 structure and a multi-directional adjustment mechanism, successfully solving the problem of multiple operations required for sealing the edges of the grooved wood board M, and achieving efficient and high-quality sealing.

[0035] Example 1 Please see Figures 3-4 This invention provides a wood panel edge banding machine, including a frame 7, a hot pressing mechanism, and a positioning module; The frame 7, as the load-bearing component of the overall equipment, can support the hot pressing mechanism and the positioning module; Figure 4 Taking the orientation sequence as an example, the hot pressing mechanism is installed on the left side of the frame 7, and the wooden board M to be sealed can be placed on the right side of the frame 7; The positioning module includes a pusher frame 9, a pusher block, a slide rod 901, a pusher cylinder 11, and a braking module 10. The pusher frame 9 is located on the side of the frame 7 away from the hot pressing mechanism. The pusher frame 9 is slidably connected to the frame 7 along the first direction X. The upper surface of the pusher frame 9 is at the same height as the surface of the frame 7 where the wooden board M is placed. The pusher block is located on the side of the pusher frame 9 away from the hot pressing mechanism. The slide rod 901 is fixedly installed on the pusher frame 9. The axis of the slide rod 901 is the same as the first direction X. The pusher cylinder 11 is installed on the frame 7. The piston rod of the pusher cylinder 11 is connected to the slide rod 901. The pusher cylinder 11 is connected to an air source and can drive the pusher frame 9 to move in the first direction X. After the wooden board M is placed on the frame 7 or the pusher frame 9, as the pusher frame 9 approaches the hot pressing mechanism in the first direction X, the pusher block will contact the wooden board M and push the wooden board M towards the hot pressing mechanism, so that the wooden board M reaches the edge sealing position and the positioning is completed.

[0036] Braking module 10 is mounted on frame 7. Braking module 10 can lock or release pusher 9 in its current position. For details, please refer to [link / reference]. Figure 4 and Figure 5 The braking module 10 includes a brake clamp 1001 and a brake cylinder 1002. The brake clamp 1001 has a through hole through which a slide rod 901 passes. The outline of the through hole is adapted to the cross-section of the slide rod 901. Taking a circular outline as an example in the figure, the brake clamp 1001 is sleeved on the outside of the slide rod 901 through the through hole. The outer wall of the brake clamp 1001 is provided with an open end connected to the through hole. Connecting plates are provided on both sides of the open end of the brake clamp 1001. The brake cylinder 1002 is mounted on one connecting plate. A through hole is provided on the other connecting plate. The diameter of the through hole is larger than the diameter of the piston rod on the brake cylinder 1002. One end of the piston rod of the brake cylinder 1002 passes through the through hole and is fixed by a limiting member, so that the braking... When the piston rod of cylinder 1002 moves towards the brake cylinder 1002, it can drive the two connecting plates to move closer to each other, reducing the gap at the opening end. This causes the side wall of the through hole to clamp the slide rod 901, locking the slide rod 901 in the current position, and thus locking the pusher 9 in the current position. When the piston rod box of brake cylinder 1002 moves away from brake cylinder 1002, the gap at the opening end increases. At this time, the side wall of the through hole no longer clamps the slide rod 901, and the slide rod 901 can move axially relative to the brake clamp 1001, unlocking the pusher 9 in the current position. In this way, during the edge sealing process of the wooden board M, the brake module 10 locks the pusher 9 in the current position, ensuring the stability of the edge sealing process.

[0037] In this embodiment, the hot pressing mechanism includes two hot pressing rollers 1, a mounting frame 3, a first driving mechanism 2, a translational frame 4, a second driving mechanism 5, and a third driving mechanism 6; The hot press roller 1 is made of aluminum and has a rectangular strip structure. Please refer to [link / reference]. Figure 6An mounting groove 101 is provided axially in the middle of the hot press roller 1. A heating element can be installed in the mounting groove 101. Each surface of the hot press roller 1 can be heated. The working temperature of the hot press roller 1 is 95℃-110℃. The heating element can be a heating rod. In order to facilitate the insertion of the heating rod, the mounting groove 101 extends through at least one end of the hot press roller 1. In this embodiment, please refer to Figure 4 The translation frame 4 is L-shaped. The frame 7 is equipped with a slide rail extending along the first direction X. The bottom of the translation frame 4 is adapted to the slide rail, so that the translation frame 4 can be slidably installed on the frame 7 along the first direction X. The first drive mechanism 2 is installed on the frame 7. The first drive mechanism 2 can be a combination of a cylinder and an air source. The output end of the first drive mechanism 2 is connected to the translation frame 4, thereby driving the translation frame 4 to move in the first direction X. Please see Figure 6 The inner side of the translation frame 4 is provided with a slide rail extending in the second direction Y. The second drive mechanism 5 is located on the top of the translation frame 4. The mounting frame 3 is generally L-shaped, and the side of the mounting frame 3 closest to the slide rail is adapted to the slide rail, so that the mounting frame 3 can be slidably mounted on the translation frame 4 in the second direction Y. Two hot press rollers 1 are mounted on the mounting frame 3. Specifically, according to... Figure 6 In the orientation sequence, the upper hot press roller 1 is fixed on the mounting frame 3. A slide rail extending in the first direction X is provided on the inner side of the mounting frame 3. A connecting seat 301 is slidably provided on the slide rail along the first direction X. The lower hot press roller 1 is fixed on the connecting seat 301, and the two hot press rollers 1 are in contact with each other, that is, the distance in the second direction Y is zero. The third drive mechanism 6 is installed on the mounting frame 3. The third drive mechanism 6 can be a combination of a cylinder and an air source. The output end of the third drive mechanism 6 is connected to the connecting seat 301, thereby driving the connecting seat 301 to move in the first direction X, and then driving the lower movable hot press roller 1 to move relative to the upper fixed hot press roller 1. In this embodiment, please refer to Figure 3 Since the hot press roller 1 is relatively long, multiple translation frames 4, first drive mechanism 2, mounting frame 3, second drive mechanism 5 and third drive mechanism 6 can be set at intervals along the length of the hot press roller 1 on the frame 7. The edge sealing operation is completed by synchronously driving the two hot press rollers 1. In this embodiment of the wood panel edge banding machine, the worker manually moves the wood panel M onto the frame 7, then places the glued edge banding strip F between the hot press roller 1 and the wood panel M. The braking module 10 first releases the pusher frame 9, and the pusher cylinder 11 drives the pusher frame 9 closer to the hot press mechanism via the slide rod 901. During this process, the pusher block pushes the wood panel M, bringing it closer to the hot press mechanism. Finally, the surface of the wood panel M to be edge banded contacts the edge banding strip F and then contacts the hot press roller 1. Figure 6In the displayed state, the pusher cylinder 11 stops working, and the braking module 10 locks the pusher frame 9; then the first drive mechanism 2, the second drive mechanism 5, and the third drive mechanism 6 cooperate to make the two hot press rollers 1 simultaneously adhere to the first edge-sealing surface M1 and the second edge-sealing surface M2; then the heating element is activated to make the surfaces of the two hot press rollers 1 reach the working temperature, and the edge-sealing strip F is hot-pressed onto the surface to be sealed, thus achieving the edge sealing of the wood board M; After the edge banding is completed, the first drive mechanism 2, the second drive mechanism 5, and the third drive mechanism 6 cooperate to move the two hot press rollers 1 away from the wooden board M. The brake module 10 releases the pusher 9, and the pusher cylinder 11 drives the pusher 9 away from the hot press mechanism through the slide rod 901. The worker removes the edge-banded wooden board M from the frame 7. It should be noted that when the surface of the wood board M to be sealed is initially positioned in contact with the hot press roller 1, the positioning can be completed by simply contacting the surface to be sealed (in this embodiment, the surface parallel to the second edge to be sealed in surface M1) with the fixed hot press roller 1. Because the other hot press roller 1 is movable, after the brake module 10 locks the pusher 9, the third drive mechanism 6 drives the other hot press roller 1 to directly press the surface to be sealed (in this embodiment, surface M2) tightly. The second drive mechanism 5 can be driven simultaneously with the third drive mechanism 6.

[0038] In this embodiment, the third drive mechanism 6 enables the individual adjustment of a hot press roller 1, which can flexibly adapt to wood boards M with different grooving depths, thus improving the adaptability of the equipment.

[0039] Example 2 The working principle of this embodiment is the same as that of embodiment 1. The main difference is that the movable hot pressure roller 1 is different among the two hot pressure rollers 1. Please see Figure 8 In this embodiment, the lower hot press roller 1 is fixedly mounted on the mounting frame 3, and the upper hot press roller 1 is slidably mounted on the mounting frame 3 along the first direction X. The upper hot press roller 1 is driven to move in the first direction X by the third driving mechanism 6, so that the upper movable hot press roller 1 moves relative to the lower fixed hot press roller 1. In this embodiment, when the surface of the wood board M to be sealed is initially positioned in contact with the hot press roller 1, the positioning can be completed by simply contacting the surface to be sealed (M2 to be sealed in this embodiment) with the fixed hot press roller 1. After the braking module 10 locks the pusher 9, the third drive mechanism 6 drives another hot press roller 1 to directly press the surface to be sealed (the surface of M1 to be sealed that is parallel to the second surface to be sealed in this embodiment).

[0040] Both Example 1 and Example 2 are preferred embodiments of the present invention.

[0041] Example 3 The difference between this embodiment and Embodiments 1 and 2 is that the structure of the hot pressing mechanism is simplified in this embodiment; Please see Figure 9 In this embodiment, there is no need to set up the translation frame 4, the second drive mechanism 5 and the third drive mechanism 6. Both hot press rollers 1 are fixed on the mounting frame 3. The mounting frame 3 is directly driven by the first drive mechanism 2. That is, the installation method of the mounting frame 3 and the frame 7 in this embodiment can be understood as the installation method of the translation frame 4 and the frame 7. This simplifies the structure of the hot press mechanism to the greatest extent. In this embodiment, the two hot press rollers 1 can only move along the first direction X under the drive of the first drive mechanism 2. In order to complete the precise edge sealing operation, firstly, after placing the wooden board M on the frame 7, the wooden board M needs to be raised so that the surface of the wooden board M to be edge sealed is at the same height as the hot pressing surface of the two hot press rollers 1. Secondly, the edge sealing strip F needs to be bent into the same shape as the surface to be edge sealed. In this embodiment, the structure of the hot pressing mechanism is simplified and the equipment usage cost is reduced, but the number of operating steps for operators increases and the technical requirements for operators are higher. The distance between the two hot pressing rollers 1 in the first direction X needs to be limited for each type of grooving depth. Therefore, this embodiment is only a feasible solution.

[0042] Example 4 This embodiment simplifies the structure of the hot pressing mechanism based on Embodiments 1 and 2, but it is more complex than the hot pressing mechanism in Embodiment 3. Please see Figure 10 In this embodiment, there is no need to set the third driving mechanism 6, but the translation frame 4 and the second driving mechanism 5 are retained. Both hot press rollers 1 are fixed on the mounting frame 3. The connection method between the mounting frame 3 and the translation frame 4 is the same as in embodiment 1, that is, the mounting frame 3 is slidably mounted on the translation frame 4 by the driving of the second driving mechanism 5. In this embodiment, the two hot press rollers 1 can move along the first direction X under the drive of the first drive mechanism 2, and can also move along the second direction Y under the drive of the second drive mechanism 5. During the edge banding operation, it is not necessary to raise the wood board M to be edge banded, nor is it necessary to bend the edge banding strip F first. However, the distance between the two hot press rollers 1 in the first direction X needs to be limited for each type of grooving depth. The production efficiency is high when edge banding the same batch of wood boards M. This embodiment is the next best solution after Embodiment 1 and Embodiment 2.

[0043] Example 5 Please see Figure 11In this embodiment, the structure of the hot pressing mechanism adopts the structure in embodiment 3, that is, both hot pressing rollers 1 are fixed on the mounting frame 3, and the mounting frame 3 is directly driven by the first driving mechanism 2; in addition, the structure of the frame 7 has been adjusted in this embodiment. Specifically, a placement frame 801 that can move along the second direction Y is provided on the frame 7. The placement frame 801 carries the wooden board M, and a fourth driving mechanism 8 is provided on the frame 7 to drive the placement frame 801 to move along the second direction Y. The fourth driving mechanism 8 can be a combination of a hydraulic cylinder and a liquid supply device. In this embodiment, the pusher 9, pusher cylinder 11, brake module 10 and other structures need to be installed on the placement frame 801, that is, the brake module 10 is set on the placement frame 801, and the pusher 9 can slide relative to the placement frame 801 in the first direction X. In this embodiment, the motion logic of the two hot press rollers 1 relative to the wooden board M is the same as in embodiment 4. That is, the two hot press rollers 1 can move relative to the wooden board M in the first direction X and the second direction Y, which has a certain degree of flexibility. However, the distance between the two hot press rollers 1 in the first direction X needs to be limited for each type of grooving depth, and the frame 7 needs to be modified to a large extent. Therefore, this embodiment is only a feasible solution.
