Description

Technical Field

[0001] The present application relates to the field of plate processing, and in particular to an edge cleaning mechanism for veneer panels. Background Art

[0002] During the production process of veneer, a piece of impregnated film paper slightly larger than the substrate area is laid on the upper and lower surfaces of the substrate, and the film paper is cured through a high-temperature hot pressing process and adhered to the substrate. After hot pressing, the excess film paper on the edge of the board needs to be cleaned. The methods used include manual cleaning or using a cleaning mechanism to complete this process.

[0003] The existing edge cleaning mechanism uses a scraper to clean the edges of the veneer board. The scraper is installed on the conveyor line of the veneer board, and the excess film paper is cleaned by the relative movement of the scraper and the veneer board. However, the end of the veneer board after edge cleaning is relatively rough, and the appearance quality is relatively low; what is worse, during the edge cleaning process, the scraper and the veneer board have a large collision, which causes depressions or gaps on the board edge, affecting the product yield. In addition, the existing edge cleaning mechanism is not suitable for conveyor lines with a faster rhythm, and when the veneer board on the conveyor line has a large deviation, the edge cleaning effect is not good. Utility Model Content

[0004] In order to improve the edge cleaning effect of veneer panels and increase product yield, the present application provides an edge cleaning mechanism for veneer panels.

[0005] The present application provides an edge cleaning mechanism for veneer panels, which adopts the following technical solution:

[0006] A veneer panel edge cleaning mechanism comprises a mounting frame and a guide plate, wherein the guide plate is slidably arranged on the mounting frame, the sliding direction of the mounting frame is arranged crosswise with its own length direction, the mounting frame is provided with a damping member, the damping member is connected to the guide plate, and the guide plate is provided with a scraper assembly.

[0007] By adopting the above technical solution, when in use, the edge cleaning mechanism is installed on the conveying line of the veneer board, and the guide plate is gradually arranged close to the veneer board along the conveying direction of the veneer board. When the veneer board in transportation contacts the guide plate, the veneer board can be guided by the guide plate, and when the veneer board moves to the scraper assembly, the scraper assembly trims the veneer board. The slidable guide plate and the damping member connected to the guide plate facilitate the guide plate to be adaptively adjusted according to the width specification of the veneer board, ensure its guiding effect, ensure that the scraper assembly stably cleans the veneer board, and then ensure the appearance quality of the veneer board; in addition, the damping member can play a buffering role on the guide plate and the veneer board, reduce the possibility of depression or notch on the edge of the veneer board, which is conducive to improving the yield of the product.

[0008] Optionally, the scraper assembly includes an upper scraper member arranged on the upper side of the guide plate and a lower scraper member arranged on the lower side of the guide plate.

[0009] By adopting the above technical solution, the upper scraper member is used to clean the edge of the film paper on the upper layer of the veneer panel, and the lower scraper member is used to clean the edge of the film paper on the lower layer of the veneer panel. The upper scraper member and the lower scraper member are independent of each other and have their own division of labor, thereby ensuring that the film paper on both sides of the veneer panel has a stable edge cleaning effect.

[0010] Optionally, the upper scraper member includes an upper scraper body disposed on the upper side of the guide plate and an upper driving source for driving the upper scraper body to swing.

[0011] By adopting the above technical solution, since the veneer panel will inevitably have a certain deformation resulting in a certain inclination at the edge of the panel, the upper scraper body can be driven to swing by the upper driving source, and the angle between the blade surface of the upper scraper body and the upper side adhesive paper can be adjusted. Then, the upper scraper body can be swung and adjusted according to the deformation of the edge of the veneer panel to improve the edge cleaning effect.

[0012] Optionally, the lower scraper member includes a lower scraper body disposed on the lower side of the guide plate and a lower driving source for driving the lower scraper body to swing.

[0013] By adopting the above technical solution, the lower scraper body is driven to swing by the lower driving source, so that the angle between the blade surface of the lower scraper body and the lower side adhesive film paper can be adjusted, and then the lower scraper body can be swung according to the deformation of the edge of the veneer panel to improve the edge cleaning effect.

[0014] Optionally, the mounting frame is provided with a guide frame, the guide frame is provided with a guide column, a sliding block is slidably penetrated through the guide column, the sliding block is connected to the guide plate, one end of the damping member is connected to the sliding block, and the other end is connected to an end of the guide frame close to the veneer panel.

[0015] By adopting the above technical solution, the movement of the sliding block is guided by the guide column, thereby ensuring the stability of the damping member when performing buffering.

[0016] Optionally, the damping member is a gas spring, one end of which is rotatably connected to the sliding block, and the other end of which is rotatably connected to an end of the guide frame close to the veneer panel.

[0017] By adopting the above technical solution, the gas spring has the functions of support and buffering. When the veneer panel collides with the guide plate, the compressibility of air is utilized to control the air pressure to achieve buffering and shock absorption. In addition, the gas spring has a large adjustment range, and its resistance and buffering force can be flexibly adjusted according to actual needs, thereby reducing the possibility of dents or gaps in the edge of the veneer panel.

[0018] Optionally, it also includes a pre-crushing wheel, which is rotatably arranged on the mounting frame and is arranged on the front side of the scraper assembly.

[0019] By adopting the above technical solution, when the veneer board passes through the pre-crushing wheel, the pre-crushing wheel can squeeze the paper edge of the veneer board, thereby crushing the film paper, and then the crushed film paper is scraped off by the scraper assembly, further improving the edge cleaning efficiency.

[0020] Optionally, a swing arm and a front driving source for driving the swing arm to swing are provided on the mounting frame, and the pre-crushing wheel is rotatably arranged on the swing arm.

The damping element can compensate for the offset of the veneer board on the conveyor line, so that the application can be applied to high-speed lines with a faster rhythm and can adapt to larger offsets during board transportation, thereby improving the applicability of the application.

[0024] 2. Through the setting of the upper scraper member and the lower scraper member, the upper scraper member cleans the edge of the film paper on the upper layer of the veneer panel, and the lower scraper member cleans the edge of the film paper on the lower layer of the veneer panel. The upper scraper member and the lower scraper member are independent of each other and have their own division of labor, ensuring that the film paper on both sides of the veneer panel has a stable edge cleaning effect.

[0025] 3. Through the setting of the pre-crushing wheel, when the veneer board passes through the pre-crushing wheel, the pre-crushing wheel can squeeze the paper edge of the veneer board, thereby crushing the film paper, and then the crushed film paper is scraped off by the scraper assembly, further improving the edge cleaning efficiency.

[0031] The following is combined with Figure 1-4 , further details of this application are given.

[0032] Example:

[0033] The present application embodiment discloses an edge cleaning mechanism for a veneer panel. Figure 1 A veneer edge cleaning mechanism includes a mounting frame 1, on which a pre-crushing wheel 2 and a scraper assembly 3 are sequentially arranged, and the pre-crushing wheel 2 is rotatably arranged on the mounting frame 1. In this embodiment, the pre-crushing wheel 2 is in the shape of a sawtooth. When in use, the edge cleaning mechanism is installed on a conveying line of veneer panels. When the veneer panels pass through the pre-crushing wheel 2, the pre-crushing wheel 2 can squeeze the paper edge of the veneer panels, thereby crushing the film paper, and then the crushed film paper is scraped off by the scraper assembly 3, so as to achieve thorough edge cleaning of the veneer panels.

[0034] Reference Figure 2 , a swing arm 11 is rotatably connected to the mounting frame 1, a front driving source 12 is installed on the mounting frame 1, one end of the front driving source 12 is rotatably connected to the mounting frame 1, and the other end is rotatably connected to the swing arm 11, and is used to drive the swing arm 11 to swing on the mounting frame 1. In this embodiment, the front driving source 12 is a cylinder, which can drive the swing arm 11 to swing, thereby realizing the position adjustment of the pre-crushing wheel 2, and then facilitating the adjustment of the position of the pre-crushing wheel 2 according to the actual width of the veneer board, so that the pre-crushing wheel 2 and the board edge of the veneer board are squeezed to a certain extent, thereby improving the applicability of the edge cleaning mechanism.

[0035] Reference Figure 1 and Figure 3, a guide plate 4 and a damping member 5 are installed on the mounting frame 1, and the scraper assembly 3 is installed on the guide plate 4. Among them, the guide plate 4 is slidably connected to the mounting frame 1, and the sliding direction of the mounting frame 1 is cross-set with its own length direction, and the damping member 5 is connected to the guide plate 4. When in use, the edge cleaning mechanism is installed on the conveying line of the veneer panel, and the guide plate 4 is gradually arranged close to the veneer panel along the conveying direction of the veneer panel. When the veneer panel in transportation contacts the guide plate 4, the veneer panel can be guided by the guide plate 4, and when the veneer panel moves to the scraper assembly 3, the scraper assembly 3 trims the veneer panel. Through the slidable guide plate 4 and the damping member 5 connected to the guide plate 4, it is convenient for the guide plate 4 to be adaptively adjusted according to the width specification of the veneer panel, to ensure its guiding effect, to ensure that the scraper assembly 3 stably cleans the veneer panel, and then to ensure the appearance quality of the veneer panel.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The scraper assembly 3 includes an upper scraper member 31 arranged on the upper side of the guide plate 4 and a lower scraper member 32 arranged on the lower side of the guide plate 4. The upper scraper member 31 is used to clean the edge of the film paper on the upper layer of the veneer panel, and the lower scraper member 32 is used to clean the edge of the film paper on the lower layer of the veneer panel. The upper scraper member 31 and the lower scraper member 32 are independent of each other and have their own division of labor, ensuring that the film paper on both sides of the veneer panel has a stable edge cleaning effect.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The upper scraper member 31 includes an upper scraper body 311 installed on the upper side of the guide plate 4 and an upper driving source 312 for driving the upper scraper body 311 to swing, and the lower scraper member 32 includes a lower scraper body 321 installed on the lower side of the guide plate 4 and a lower driving source 322 for driving the lower scraper body 321 to swing. In this embodiment, the upper driving source 312 and the lower driving source 322 are both cylinders. Since the veneer board inevitably has a certain deformation, resulting in a certain inclination of the board edge, the upper scraper body 311 is driven to swing by the upper driving source 312, and the angle between the blade surface of the upper scraper body 311 and the upper side adhesive film paper can be adjusted. The lower scraper body 321 is driven to swing by the lower driving source 322, and the angle between the blade surface of the lower scraper body 321 and the lower side adhesive film paper can be adjusted. Then, the upper scraper body 311 and the lower scraper body 321 can be swung and adjusted according to the deformation of the veneer board edge, thereby improving the edge cleaning effect.

[0038] Reference Figure 1 and Figure 3The guide frame 6 is fixed on the mounting frame 1, and the guide frame 6 is fixed with a guide column 61. Two guide columns 61 are provided, and the same sliding block 62 is slidably penetrated on the two guide columns 61. The sliding block 62 is fixedly connected to the guide plate 4 through an L-shaped connecting plate 621. One end of the damping member 5 is connected to the sliding block 62, and the other end is connected to the end of the guide frame 6 close to the veneer. In this way, the movement of the sliding block 62 is guided by the guide column 61, which ensures the stability of the damping member 5 when performing buffering.

[0039] Reference Figure 3 The damping member 5 is a gas spring, one end of which is rotatably connected to the sliding block 62, and the other end of which is rotatably connected to the end of the guide frame 6 close to the veneer. Since the gas spring has the functions of support and buffering, when the veneer and the guide plate 4 collide, the compressibility of air is utilized to control the air pressure to achieve buffering and shock absorption, and the adjustment range is large, and the resistance and buffering force can be flexibly adjusted according to actual needs, reducing the possibility of depression or notch on the edge of the veneer.

[0040] The implementation principle of the edge cleaning mechanism for veneer panels in the embodiment of the present application is as follows: when in use, the edge cleaning mechanism is installed on the conveying line of the veneer panels, and the guide plate 4 is arranged gradually close to the veneer panels along the conveying direction of the veneer panels. When the veneer panels pass through the pre-crushing wheel 2, the pre-crushing wheel 2 can squeeze the paper edge of the veneer panels, thereby crushing the film paper; when the veneer panels in transportation contact the guide plate 4, the guide plate 4 can guide the veneer panels; when the veneer panels move to the scraper assembly 3, the scraper assembly 3 trims the veneer panels.

[0041] The slidable guide plate 4 and the damping member 5 connected to the guide plate 4 can facilitate the guide plate 4 to be adaptively adjusted according to the width specification of the veneer panel, thereby ensuring its guiding effect and ensuring that the scraper assembly 3 can stably clean the edges of the veneer panel, thereby ensuring the appearance quality of the veneer panel; in addition, the damping member 5 can play a buffering role for the guide plate 4 and the veneer panel, reducing the possibility of dents or gaps on the edges of the veneer panel, which is beneficial to improving the yield of the product.

[0042] In addition, the damping element 5 can be used to compensate for the offset of the veneer board on the conveyor line, so that the present application can be applied to high-speed lines with a faster rhythm and can adapt to larger offsets during board transportation, thereby improving the applicability of the present application.

[0043] In the present application, the upper scraper member 31 is used to clean the edges of the adhesive paper on the upper layer of the veneer panel, and the lower scraper member 32 is used to clean the edges of the adhesive paper on the lower layer of the veneer panel. The upper scraper member 31 and the lower scraper member 32 are independent of each other and have their own division of labor, ensuring that the adhesive paper on both sides of the veneer panel has a stable edge cleaning effect.

[0044] Taking into account that the veneer panel will inevitably have a certain deformation resulting in a certain inclination of the panel edge, the upper scraper body 311 and the lower scraper body 321 in the present application can both be adjusted in position by swinging, thereby improving the applicability and practicality of the edge cleaning mechanism.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
