[0031] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Referring to Figure 1-6 As shown, the present invention provides an edge banding machine head alignment and anti-collision plate device, including:

[0033] A fixed seat 1 is provided with a fixed block 2 on it. The fixed block 2 has a first surface 20, and the first surface 20 is used to abut against the plate conveyed from the edge banding machine. When the plate moves to the head alignment device, the fixed block 2 is in vertical contact with the plate, and the plate is abutted by the first surface 20. Then, the cutting unit in the edge banding machine cuts the excess edge banding material of the plate. The edge line of the first surface 20 is flush with or at least partially protrudes from the edge line of the fixed seat 1, so as to ensure that only the first surface 20 abuts against the plate. The component composed of the fixed seat 1 and the fixed block 2 is the anti-collision plate template in the prior art. In order to ensure the vertical abutment between the fixed block 2 and the plate, the fixed seat 1 and the fixed block 2 are generally made of metal materials or rigid materials that are not easily deformed. During the cutting process, the plate moves along the preset path and slides relative to the fixed block 2. At this time, the metal fixed block 2 will generate friction with the plate, which is likely to cause damage to the surface of the plate.

[0034] To solve the problem of the plate being bumped and worn by the fixed block 2, an anti-collision component 3 is provided. The anti-collision component 3 includes a first sliding wheel 30, a second sliding wheel 31 and a belt 32. The first sliding wheel 30 and the second sliding wheel 31 are respectively arranged on the fixed seat 1. The first sliding wheel 30 is arranged at one end of the fixed block 2 along the first direction D1, and the second sliding wheel 31 is arranged at the other end of the fixed block 2 along the first direction D1. The belt 32 is wound around the first sliding wheel 30 and the second sliding wheel 31. The extension line of the first surface 20 is tangent to both the first sliding wheel 30 and the second sliding wheel 31. When the plate is conveyed to the first surface 20, the belt 32 slides along the first surface 20 with the movement of the plate.

[0035] In this embodiment, the first direction D1 is the direction of gravity. This embodiment also includes a second direction D2, and the second direction D2 is perpendicular to the first direction D1.

[0036] In this embodiment, the fixed block 2 is enclosed in the space formed by the first sliding wheel 30, the second sliding wheel 31 and the belt 32, and the extension line of the first surface 20 is tangent to both the first sliding wheel 30 and the second sliding wheel 31, which ensures that the belt 32 covers the first surface 20. Therefore, when the fixed block 2 slides relative to the plate, the first sliding wheel 30 and the second sliding wheel 31 drive the belt 32 to move on the first surface 20, so that the contact between the fixed block 2 and the plate is changed to the contact between the belt 32 and the plate. Since the belt 32 has a certain flexibility, it will not cause wear to the surface of the plate during the relative sliding process, thus reducing the damage to the plate and improving the edge sealing quality.

[0037] Embodiment 1

[0038] See Figure 2-3 As shown, the fixed block 2 has a second surface 21 opposite to the first surface 20. A preset distance is provided between the second surface 21 and the belt 32. A support member is connected to the second surface 21. One end of the support member abuts against the belt 32. The support member is used to connect the belt 32 and the second surface 21. The purpose of having a preset distance between the second surface 21 and the belt 32 is to prevent the belt 32 from contacting the second surface 21 and causing multiple wear of the belt 32. Considering that there is a risk of detachment if the side of the belt 32 close to the second surface 21 does not contact at all, the support member is provided to guide the belt 32 and prevent the belt 32 from detaching during high-speed transmission.

[0039] Further, see Figure 4-5 As shown, the support member can be a bent elastic piece 40. One end of the elastic piece 40 is connected to the second surface 21, and the other end of the elastic piece 40 abuts against the belt 32. The elastic piece 40 has a certain flexibility and gives a supporting force to the belt 32 during the rotation of the belt 32 to prevent it from deviating from the running track. Moreover, the contact surface between the elastic piece 40 and the belt 32 is small, and the resulting wear is also small. The end of the elastic piece 40 in contact with the belt 32 is preferably set as an arc surface to reduce the friction with the belt 32;

[0040] The support member can also be a fourth sliding wheel 41. The fourth sliding wheel 41 is connected to the second surface 21. The tangent plane of the fourth sliding wheel 41 abuts against the belt 32. The fourth sliding wheel 41 can slide relative to the belt 32 when the belt 32 rotates. It can not only support the belt 32 in this section, but also improve the smoothness of the rotation of the belt 32 and make the rotation of the belt 32 more smooth.

[0041] It should be noted that in order to reduce the contact between the fixed block 2 and the belt 32, the length of the second surface 21 can be less than that of the first surface 20, and only a part is needed for connecting the support member. Therefore, the shape of the fixed block 2 can be changed according to the actual situation, that is, the fixed block 2 can be in an irregular shape, which can not only reduce the contact surface with the belt 32, but also help to reduce the cost. In addition, in order to adapt to the shapes of the first sliding wheel 30 and the second sliding wheel 31 at both ends of the fixed block 2, the sides of the fixed block 2 close to the first sliding wheel 30 and the second sliding wheel 31 can be set to be arc-shaped, and the specific structure is not limited herein.

[0042] Embodiment 2

[0043] See Figure 1-6 As shown, the diameter of the first sliding wheel 30 is greater than or equal to the diameter of the second sliding wheel 31. As a preferred method, the diameter of the first sliding wheel 30 is greater than the diameter of the second sliding wheel 31, and a height difference is formed between the first sliding wheel 30 and the second sliding wheel 31, making it more labor-saving for the belt 32 to rotate. Those skilled in the art should know that the diameter of the first sliding wheel 30 can also be equal to the diameter of the second sliding wheel 31, which will not be elaborated here.

[0044] Embodiment 3

[0045] See Figure 1-5 As shown, a third sliding wheel 5 is provided on the fixed seat 1. The third sliding wheel 5 is arranged on one side of the first sliding wheel 30 along the second direction D2, and the tangent of the third sliding wheel 5 and the first sliding wheel 30 in the second direction D2 is parallel. The sheet first undergoes relative sliding with the belt 32 at the first surface 20, and then the sheet passes over the first sliding wheel 30 along the second direction D2. By providing the third sliding wheel 5 flush with the first sliding wheel 30, it can effectively prevent the sheet from directly contacting the metal surface when moving in the second direction D2, thus avoiding bumps or damage.

[0046] Furthermore, see Figure 1-5 As shown, a stop block 6 is provided on the fixed seat 1. The stop block 6 is arranged between the first sliding wheel 30 and the third sliding wheel 5, and the shape of the stop block 6 is adapted to the outer circumferences of the first sliding wheel 30 and the third sliding wheel 5. The stop block 6 can divide and limit the first sliding wheel 30 and the third sliding wheel 5, ensuring that the first sliding wheel 30 and the third sliding wheel 5 operate on their respective rotation trajectories.

[0047] Embodiment 4

[0048] See Figure 1-6As shown, on one side of the fixed seat 1 away from the fixed block 2, there is an installation part 7. One end of the installation part 7 is connected to the fixed seat 1, and the other end of the installation part 7 extends to the outside of the fixed seat 1. The installation part 7 is used to connect the fixed seat 1 with the trimming device, and the structure of the installation part 7 can be customized according to different edge banding machines.

[0049] See Figure 6 As shown, in order to prevent workers from being scratched when installing the installation part 7, chamfered parts 70 can also be provided at multiple corners of the installation part 7 to reduce the sharp edges of the installation part 7. The specific structure is not limited here.

[0050] Furthermore, see Figure 1-6 As shown, a plurality of installation holes 8 are provided on the fixed seat 1, the fixed block 2 and the installation part 7. The installation holes 8 are used to connect the trimming device. It should be noted that in order to prevent the anti-collision component 2 and the third sliding wheel 5 from detaching from the fixed seat 1, a fixing plate (not shown in the figure) can also be provided to encapsulate the first sliding wheel 30, the second sliding wheel 31 and the third sliding wheel 5 to increase the stability of the device.

[0051] In a feasible implementation manner, see Figure 4-6 As shown, a plurality of chip discharging holes 9 are also provided on the fixed seat 1. The chip discharging holes 9 penetrate through the fixed seat 1, and the fine chips generated during the cutting process can be discharged from the chip discharging holes 9 to prevent them from being blocked in the anti-collision component 3 and affecting the normal rotation of the belt 32.

[0052] Furthermore, see Figure 6 As shown, a recessed part 10 is formed by the inward depression of the surface of the fixed seat 1 facing away from the fixed block 2. The recessed part 10 is used to avoid the edge banding unit and prevent the edge banding unit from colliding with the fixed seat 1 and affecting the cutting.

[0053] In a feasible implementation manner, see Figure 1-5 As shown, a rubber layer 33 is wrapped around the outer peripheries of the first sliding wheel 30 and the third sliding wheel 5. In this embodiment, the second sliding wheel 31 is set as the driving wheel, and the first sliding wheel 30 is the driven wheel. Wrapping the rubber layer 33 around the outer periphery of the first sliding wheel 30 can reduce the wear on the belt 32, and wrapping the rubber layer 33 around the outer periphery of the third sliding wheel 5 is to reduce the frictional loss between the plate and the third sliding wheel 5.

[0054] Based on the above embodiments, the working process of the edge banding machine's head alignment and anti-collision plate device of the present application is as follows: It is connected to the head alignment device through the mounting member 7. The first surface 20 is the surface that is in vertical contact with the board. When the board reaches the position of the first surface 20, the first surface 20 abuts against the board. During the relative movement between the fixed seat 1 and the board, the second sliding wheel 31 drives the first sliding wheel 30 to rotate. At this time, the belt 32 undergoes relative sliding with the first surface 20, and the board comes into contact with the belt 32. During the sliding process, due to the flexibility of the belt 32, it avoids the friction between the board and the first surface 20 of the metal surface. After the cutting unit completes the cutting, the board passes over the first sliding wheel 30 and the third sliding wheel 5 along the second direction D2. The outer peripheries of the first sliding wheel 30 and the third sliding wheel 5 are provided with a rubber layer 33, which further avoids the collision with the board, effectively preventing the fixed block 2 from scratching or damaging the board when it contacts the board, and greatly improving the edge banding quality.

[0055] The above has detailedly described the structure, features, and function effects of the present utility model based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present utility model, but the present utility model is not limited to the scope defined by the drawings. Any changes made according to the concept of the present utility model, or equivalent embodiments modified into equivalent changes, still within the spirit covered by the description and the drawings, should be within the protection scope of the present utility model.
