[0028] Please combine Figure 1 and Figure 2 The edge banding machine provided in the present application includes an edge banding workbench 100, a first push wheel 210, a second push wheel 220 and a pressure roller 230. The first push wheel 210 and the second push wheel 220 are rotatably installed on the edge banding workbench 100 at an interval. The first push wheel 210 and the second push wheel 220 are used to convey the plate along the first direction O. The pressure roller 230 is used to wind the edge banding tape. The pressure roller 230 is rotatably installed on the edge banding workbench 100. The pressure roller 230 is adjacent to the first push wheel 210 and the second push wheel 220. The direction from the second push wheel 220 to the pressure roller 230 is the second direction P. The angle between the first direction O and the second direction P is an acute angle.

[0029] Among them, the plate (see Figure 2 The dotted part in the figure) is placed in the gap between the first push wheel 210 and the second push wheel 220, and moves forward under the clamping and pushing of the first push wheel 210 and the second push wheel 220. The first direction O is the thrust direction of the first push wheel 210 and the second push wheel 220 on the plate, and the second direction P is the pressure direction of the pressure roller 230. The angle between the second direction P and the first direction O is an acute angle. The thrust in the first direction O can generate a component force in the second direction P, so that the plate is pressed and bonded with the edge banding wound on the pressure roller 230. Compared with manually pushing the plate and pressing the edge band, the plate in this embodiment is pushed by the first push wheel 210 and the second push wheel 220, the magnitude of the pushing force is stable, and the pushing direction is stable in the first direction O, the second direction P between the second push wheel 220 and the pressure roller 230 is fixed, and the spacing is fixed, that is, the pressure applied by the pressure roller 230 to the edge band on the edge of the plate is stable, including the magnitude of the pressure applied by the pressure roller 230 is stable, and the pressure direction is stable in the second direction P, so that the plate is under the thrust in the first direction O, and the edge band is under the pressure in the second direction P, and the two are stably bonded, which improves the bonding force between the edge band and the plate, and reduces the glue line on the appearance. According to the synthesis and decomposition of the force, the plate with edge banding is fed along the third direction Q. Among them, the second direction P is perpendicular to the third direction Q.

[0030] The edge banding machine provided in this embodiment is provided with a first push wheel 210 and a second push wheel 220, so as to have automatic material pushing. The pushing direction (first direction O) of the first push wheel 210 and the second push wheel 220 is in an acute angle relationship with the pressure direction (second direction P) of the pressure roller 230. At the same time, the first push wheel 210 and the second push wheel 220 provide a thrust in the feeding direction and the axial direction of the pressure roller 230, so as to realize the function of automatically pushing the plate to the pressure roller 230 and automatically pushing the plate to feed, thereby improving the level of automation and reducing the labor intensity of workers. Compared with manual lamination, the thrust of the first push wheel 210 and the second push wheel 220 and the pressure of the pressure roller 230 are more stable and uniform and have greater pressure, thereby enhancing the edge banding adhesion and improving the appearance quality of the special-shaped edge banding. In this way, the edge banding machine provided in this embodiment, firstly, some actions are automatically replaced and assisted by manual labor, which can reduce labor intensity and improve processing efficiency; secondly, the pressure of the edge banding pressure roller 230 is greater and more uniform, which can improve the edge banding adhesion strength, reduce the glue line, reduce the probability of glue seam generation, and improve the quality of edge banding products.

[0031] In addition, the edge banding machine can achieve an efficient edge banding process. Due to the effective conveying of the first push wheel 210 and the second push wheel 220, and the cooperation of the pressure roller 230 with the first push wheel 210 and the second push wheel 220, compared with manual operation, a fast and stable edge banding operation can be achieved, thereby improving production efficiency. The adhesion between the edge banding tape and the board is better, and the appearance of the glue line can be reduced. Therefore, the appearance of the board after edge banding is neater and more beautiful.

[0032] In one embodiment, in combination Figure 1 and Figure 2 The first push wheel 210 is located above the second push wheel 220, and the first push wheel 210 and the second push wheel 220 are arranged at intervals. The plate can be placed horizontally and pass between the first push wheel 210 and the second push wheel 220. The first direction O is the horizontal direction. The first direction O is perpendicular to the gravity direction, and the two do not interfere with each other. Compared with the inclined or vertical placement of the plate, which will be offset due to the influence of gravity, it is conducive to the stable feeding of the plate. The horizontally placed plate moves stably horizontally under the action of gravity and thrust, thereby increasing the position stability and controllability of the plate, which is conducive to the subsequent pressure between the plate and the edge band being more stable, improving the adhesion between the edge band and the plate, reducing the appearance of glue lines, and having higher edge banding quality, which helps to reduce problems such as cracking and debonding, and makes the appearance of the edge-banded plate more beautiful.

[0033] In some embodiments, in combination Figure 1The edge banding machine further includes a suspension arm 110, a first end of which is mounted on the top of the edge banding workbench 100, a second end of which is located above the edge banding workbench 100, and a first push wheel 210 is rotatably mounted on the second end of the suspension arm 110. The suspension arm 110 is connected to the top of the edge banding machine to form a more solid structure, which can increase the installation stability of the first push wheel 210 and help reduce the position deviation of the first push wheel 210 caused by vibration or violent movement. The suspension arm 110 suspends the first push wheel 210 from above the edge banding workbench 100, so that the first push wheel 210 and the second push wheel 220 are arranged up and down. The hanging arm 110 is installed at a certain distance from the second push wheel 220, and then extends to the top of the second push wheel 220 to facilitate the assembly of the first push wheel 210. The hanging arm 110 does not occupy the space where the second push wheel 220 is located, which is beneficial to the transportation and feeding of the plate, and facilitates the first push wheel 210 and the second push wheel 220 to push the material in sufficient space, and the pressure roller 230 to perform edge sealing operations in sufficient space.

[0034] In one embodiment, the arm 110 includes a first arm 111, a second arm 112 and a third arm 113. The first arm 111 is vertically mounted on the edge banding workbench 100, the second arm 112 is horizontally arranged, the two ends of the second arm 112 are respectively connected to the first arm 111 and the third arm 113, the third arm 113 is vertically arranged, there is a gap between the third arm 113 and the edge banding workbench 100, and a rotatable first push wheel 210 is installed at the end of the third arm 113. In this way, the arm 110 is installed at a horizontal distance from the second push wheel 220 by the length of the second arm 112 through the first arm 111, providing a larger operating space for the second push wheel 220 and the pressure roller 230. The structure of the arm 110 also allows a larger operating space above the edge banding machine, so that the operator can move and handle the panels more freely, and adjust the edge banding belt conveniently. At the same time, during the operation of the edge banding machine, the structure of the arm 110 will not cause interference to the workbench part. Since there is a gap between the third arm 113 and the edge banding workbench 100 , cleaning and maintenance of the edge banding workbench 100 becomes more convenient, and cleaning tools can easily enter the space between the boom 110 and the workbench to perform necessary cleaning and maintenance work.

[0035] Optionally, the first push wheel 210 is adjustably mounted on the third arm 113, and the position can be adjusted as needed to achieve a more precise edge banding operation. The operator can flexibly adjust the position of the first push wheel 210 according to panels of different sizes and shapes to meet edge banding requirements.

[0036] Specifically, the first push wheel 210 is located on a side of the third arm 113 close to the first arm 111. In other words, the first push wheel 210 is located between the third arm 113 and the first arm 111 in the horizontal direction, and the first push wheel 210 is located between the second arm 112 and the edge banding workbench 100 in the vertical direction, thereby forming a semi-enclosed protection structure for the first push wheel 210, preventing external structures or personnel from interfering with the first push wheel 210 during the edge banding operation, thereby improving the safety and stability of the edge banding operation.

[0037] Specifically, the lower edge of the first push wheel 210 is lower than the end of the third arm 113, so that the lower edge of the first push wheel 210 can better contact the plate and apply more uniform pressure. The lower edge of the first push wheel 210 protrudes from the end of the third arm 113, so that the end of the third arm 113 does not block or interfere with the first push wheel 210 from blocking the plate, and the plate does not touch the end of the third arm 113, ensuring the smooth progress of the edge sealing operation.

[0038] Optionally, the upper edge of the first push wheel 210 is higher than the end of the third arm 113, and the upper edge of the first push wheel 210 does not need to abut against the plate. The upper edge of the first push wheel 210 is protected by the third arm 113 to prevent external structures or personnel from interfering with the upper half of the first push wheel 210, thereby improving the rotation stability and reliability of the first push wheel 210.

[0039] In some embodiments, the first push wheel 210 and the second push wheel 220 are arranged in parallel and spaced apart. When the first push wheel 210 and the second push wheel 220 push the plate, a uniform contact surface is formed on the upper and lower sides of the plate. This ensures that pressure is evenly applied during the edge banding process, thereby improving the bonding performance between the edge banding tape and the plate. The tangent direction of the lower edge of the first push wheel 210 is the same as the tangent direction of the upper edge of the second push wheel 220, that is, the thrust direction applied to the plate by the first push wheel 210 and the second push wheel 220 is the same, which is conducive to the plate receiving a stable thrust and facilitating a stable edge banding operation of the plate.

[0040] Optionally, the interval between the first push wheel 210 and the second push wheel 220 is adjustable to accommodate panels of different shapes and sizes. Whether it is a flat plate, a curved surface or other complex-shaped panels, the interval between the first push wheel 210 and the second push wheel 220 can be adjusted to ensure a clamping effect and achieve good edge sealing quality.

[0041] In some embodiments, the first push wheel 210 and the second push wheel 220 have the same size and torque, so that the thrust applied to the plate by the first push wheel 210 and the second push wheel 220 is the same, which is beneficial for the plate to receive stable thrust and facilitates stable edge sealing operation of the plate.

[0042] In some embodiments, at least one of the first push wheel 210 and the second push wheel 220 is connected to a driving member and rotates under the driving of the driving member.

[0043] Optionally, the first push wheel 210 and the second push wheel 220 are respectively connected to the driving member and can both actively rotate, that is, the first push wheel 210 and the second push wheel 220 are both active wheels to enhance the thrust on the plate.

[0044] Optionally, one of the first push wheel 210 and the second push wheel 220 is connected to the driving member, and the other of the first push wheel 210 and the second push wheel 220 is rotatably arranged but not connected to the driving member, that is, one of the first push wheel 210 and the second push wheel 220 is a driving wheel, and the other of the first push wheel 210 and the second push wheel 220 is a driven wheel, which saves power or transmission mechanism. At the same time, the plate located between the driving wheel and the driven wheel can push the plate to feed when the driving wheel rotates, and the driven wheel rotates accordingly, that is, the first push wheel 210 and the second push wheel 220 rotate synchronously.

[0045] In some embodiments, the first push wheel 210 and the second push wheel 220 rotate around the horizontal axis respectively, so that the tangential directions of the contact points of the first push wheel 210 and the second push wheel 220 with the plate are the same, that is, the directions of pushing the plate to feed are the same, so that the plate can stably obtain the thrust in the first direction O, avoiding the need for partial mutual offset due to the different thrust directions between the first push wheel 210 and the second push wheel 220, thereby improving the utilization rate of the rotational torque of the first push wheel 210 and the second push wheel 220 and achieving energy saving.

[0046] In some embodiments, the pressure roller 230 rotates around a vertical axis so that the tangent direction of the contact point between the pressure roller 230 and the edge banding strip is horizontal, and the pressure direction of the pressure roller 230 is perpendicular to the edge of the horizontally placed panel, thereby ensuring close contact between the edge banding strip and the panel and improving the edge banding quality.

[0047] In some embodiments, the pressure roller 230 is located on one side of the second push wheel 220 in the first direction O, so that the thrust of the first push wheel 210 and the second push wheel 220 on the plate drives the plate to be pressed onto the pressure roller 230, thereby enhancing the pressing force between the plate and the edge band, and the pressure roller 230 can better fit the edge band and the plate, ensuring the firmness and durability of the edge band. By working in coordination with the second push wheel 220, a better edge banding effect can be achieved, reducing the occurrence of glue lines and other undesirable conditions.

[0048] In one embodiment, the angle between the first direction O and the second direction P is 15° to 60°. A suitable angle can ensure a stronger connection between the edge band and the panel, thereby improving the durability and quality of the edge band.

[0049] If the angle between the first direction O and the second direction P is greater than 60°, the component of the thrust of the first push wheel 210 and the second push wheel 220 in the second direction P is reduced, so that the pressing force between the panel and the edge band is reduced. At the same time, the kinetic energy of the first push wheel 210 and the second push wheel 220 is wasted, and the component of the thrust perpendicular to the second direction P is increased, resulting in the panel moving too fast and insufficient bonding time and adhesion time between the panel and the edge band.

[0050] If the angle between the first direction O and the second direction P is less than 15°, the thrust component of the first push wheel 210 and the second push wheel 220 in the second direction P is too large, causing the plate to collide with the pressure roller 230, and the pressing force between the plate and the edge banding is too large, which will squeeze out the glue between the plate and the edge banding, resulting in poor bonding effect. At the same time, the thrust component perpendicular to the second direction P is reduced, causing the plate to move too slowly, and the edge banding efficiency needs to be improved.

[0051] In some embodiments, in combination Figure 1 The edge banding machine also includes a glue coating shaft 240, which is arranged upstream of the pressure roller 230. The edge banding belt passes through the glue coating shaft 240 and the pressure roller 230 in sequence, and is first coated with glue and then bonded and fixed to the edge of the plate.

[0052] In some embodiments, in combination Figure 1 The edge banding machine also includes a working suction cup 250, which can absorb the plate and place the plate on the edge banding workbench 100, thereby improving the automation level of the edge banding machine and reducing manual work.

[0053] In some embodiments, in combination Figure 1 The edge banding machine further includes an edge banding tray 260 , on which the edge banding is wound and used for storing and supplying the edge banding.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
