Description

Technical Field

[0001] The present invention relates to the field of sheet material grinding production, and specifically to a grinding device for the edges of sheet materials. Background Art

[0002] During the processing of sheet materials, in order to avoid problems such as deformation and delamination caused by moisture absorption, which affect the use of furniture, it is necessary to perform edge sealing on the sides of the sheet materials. Edge sealing is to use an edge sealer to paste an edge banding strip on the side of the sheet material, and its quality is directly related to the overall quality of the product. In addition, after edge sealing, trimming is also required, that is, cutting off the excess edge banding strip that extends beyond both sides of the sheet material. Trimming can not only improve the appearance and quality of the sheet material, but also prevent damage to the edges, peeling or flaking of the veneer layer during transportation and use, and at the same time play a role in waterproofing, sealing the release of harmful gases and reducing deformation.

[0003] Currently, in order to achieve the automation of sheet material edge sealing, existing technologies use edge sealing equipment to sequentially complete operations such as conveying, gluing, cutting, and upper and lower trimming of the edge sealing. However, in actual production, directly performing trimming after the edge banding strip is pasted may cause the edge banding strip not to be fully adhered to the side of the sheet material, resulting in the displacement of the trimming strip and affecting the quality of the edge banding strip; in addition, during the trimming process, when only using a trimming wheel to handle the excess glue, the glue will adhere to the trimming wheel, seriously affecting the trimming effect.

Specific implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0019] During the process of sheet processing, edge banding is a crucial step to prevent the sheet from getting damp and deforming, and to ensure the quality of furniture. Edge banding involves pasting edge banding strips, and their quality directly affects the overall quality of the product. The trimming process improves the appearance, prevents damage, achieves a waterproof effect, seals harmful gases, and reduces deformation by cutting off the excess edge banding strips. During the pasting of the edge banding strips, excess glue and edge banding strips protruding from the sheet are generated. In actual production, an edge banding integrated machine is usually used to trim the edge banding strips. However, direct trimming can cause displacement between the edge banding strip and the sheet, affecting the pasting quality of the edge banding strip. Or, when using a trimming wheel to handle the excess glue, it will seriously affect the trimming effect. The present invention provides a grinding device for the edge of a sheet, which uses a grinding component 4 to first cut off the excess glue on the side of the sheet and then perform grinding, thereby completing the trimming operation of the sheet.

[0020] As Figures 1-8 shown, in some embodiments, a grinding device for the edge of a sheet includes a support component 1, a grinding component 4, and a side pressing component 5. Among them, the support component 1 serves as the foundation of the entire device, providing a stable working platform for the entire device. The grinding component 4 is installed on the upper part of the support component 1 and is responsible for grinding the edge of the sheet 2. The side pressing component 5 is embedded inside the support component 1 to ensure that the sheet 2 can remain stable during the grinding process.

[0021] On both sides of the grinding component 4, upper pressure roller assemblies 3 are respectively equipped. The main function of these upper pressure roller assemblies 3 is to fix the upper surface of the sheet 2 to ensure that the sheet 2 does not move or deform during the grinding process, thereby guaranteeing the precision and effect of grinding.

[0022] Specifically, the grinding component 4 includes a cutting mechanism and a polishing mechanism. The cutting mechanism is arranged on the front side of the polishing mechanism and is responsible for cutting off the excess glue and label strips at the edge of the sheet 2. To achieve this purpose, a cutting knife 46 is provided in the cutting mechanism, and this operation is completed through the cutting knife 46.

[0023] Immediately following, a polishing roller 45 is specially designed in the polishing mechanism. The surface of the sheet 2 is ground and polished through the polishing roller 45 to make it smooth and flat.

[0024] In the side pressing component 5, a pressing block 53 is provided, and a pressing plane 532 and a pressing vertical surface 531 are provided in the pressing block 53. The pressing plane 532 and the pressing vertical surface 531 are vertically intersecting. Such a design can ensure that the pressing plate can be firmly connected to the side of the sheet 2, and at the same time, the pressing plane 532 can carry the sheet 2 to keep it stable during the grinding process. This design not only improves the precision of grinding but also ensures the safety of the operation.

[0025] It should be noted that according to the width of the plate 2, the distance between the two side pressing components 5 is adjusted so that the pressing vertical surface 531 fits against the side of the plate 2, providing a lateral pressure to the plate 2, effectively preventing the edge banding from shifting during the grinding process, thereby affecting the grinding quality of the plate 2.

[0026] Similarly, according to the width of the plate 2, the distance between the two fixing mechanisms is adjusted, and the distance between the two cutting mechanisms is adjusted.

[0027] The plate 2 moves forward through the conveying component 6, and the upper roller component 3 presses against the upper surface of the plate 2 from above. While the plate 2 moves forward, the upper roller 33 rotates as the plate 2 moves. The cutting knife 46 cuts off the glue overflowing from the edge of the plate 2 and the edge banding protruding above the surface of the plate 2. Subsequently, the polishing roller 45 polishes the surface of the plate.

[0028] The side of the plate 2 contacts and slides with the pressing vertical surface 531, while the bottom surface of the plate 2 contacts the pressing plane 532, thereby supporting the bottom of the plate 2. The upper surface of the plate 2 contacts the upper roller component 3, pressing the upper surface of the plate 2, fixing its sides and upper and lower surfaces, ensuring that the plate remains stable during the grinding process to ensure the precision and effect of grinding.

[0029] Subsequently, the plate 2 completes the edge trimming process through the coordinated operation of the cutting mechanism and the polishing mechanism. Specifically, first, the cutting knife 46 cuts off the excess glue at the edge of the plate 2, and then the polishing roller 45 polishes the surface of the plate 2 to improve the edge trimming quality and ensure the smoothness and overall quality of the edge of the plate 2.

[0030] Such as Figure 3 and Figure 4 As shown, in some embodiments, the support component 1 includes two fixed frames 11, two support columns 12, a transmission lead screw 14, a guiding optical rod 15, and two connecting sliding plates 16.

The two ends of the transmission lead screw 14 are respectively axially connected to the two support columns 12, ensuring that the transmission lead screw 14 can be stably connected to the support columns 12 and can rotate smoothly, and enabling the transmission connection between the transmission lead screw 14 and the grinding component 4, driving the grinding component 4 to move through the transmission lead screw 14. The guiding optical rod 15 is arranged above the transmission lead screw 14, and the guiding optical rod 15 is slidably connected to the grinding component 4 to achieve precise positioning and movement of the grinding component 4.

[0031] Two connecting slides 16 are respectively arranged on both sides of the support column 12, and a slide groove is provided on the connecting slide 16, which is slidably connected with the side pressing assembly 5 through the slide groove, so that the side pressing assembly 5 can be adjusted as needed. The side pressing assembly 5 is connected to the inner side of the fixed frame 11, and the side pressing assembly 5 is supported by the fixed frame 11. The upper pressure roller assembly 3 is connected to the upper part of the fixed frame 11, and is used to apply pressure to the plate 2 to ensure that the plate 2 remains stable during the grinding process.

[0032] A first motor 13 is provided at one end of the transmission screw 14 , and the first motor 13 is fixedly connected to the outer side of the support column 12 . The transmission screw 14 can be rotated by the drive of the first motor 13 , thereby driving the grinding assembly 4 to be precisely positioned.

[0033] A plurality of columns 17 are provided at the lower portion of the fixing frame 11 , and these columns 17 are respectively arranged on both sides of the supporting column 12 to provide additional support and stability, thereby ensuring the stability and durability of the entire device during operation.

[0034] like Figures 7-9 As shown, in some embodiments, two grinding assemblies 4 are provided, and the two grinding assemblies 4 are respectively arranged on two side edges of the plate 2 , and the grinding operation is performed on both side edges of the plate 2 through the grinding assemblies 4 .

In order to realize the driving of the grinding assembly 4, a threaded hole and a through hole are provided on the slider 41, wherein the threaded hole is used to connect with the transmission screw 14, and the through hole is used to slide and connect with the guide light rod 15, so as to realize the precise movement of the slider 41.

[0036] The upper part of the connecting plate 43 is fixedly connected to the bottom of the slider 41, ensuring the stability and accuracy of the grinding assembly 4. The lower part of the connecting plate 43 is provided with a cutting mechanism and a polishing mechanism, which are responsible for cutting and polishing the edge of the plate 2. In addition, the second motor 42 is arranged on the upper part of the connecting plate 43, and is connected to the polishing mechanism through a transmission to ensure that the polishing mechanism can work efficiently. Through such a design, the two grinding assemblies 4 can work together to synchronously grind the two sides of the plate 2, thereby improving work efficiency and grinding quality.

[0037] Furthermore, in some embodiments, the cutting mechanism further includes a damping rod 47 and a spring 48. Specifically, the spring 48 is disposed on the outside of the damping rod 47, and the two ends of the damping rod 47 are respectively connected to the connecting plate 43 and the cutting blade 46. The function of the spring 48 is to adjust and maintain the appropriate distance between the cutting blade 46 and the plate 2, so as to ensure that during the cutting process, the cutting blade 46 can contact the surface of the plate 2 with a constant pressure, thereby achieving a uniform and efficient cutting effect. Through this design, the problem of uneven grinding caused by the thickness change of the plate 2 or the wear of the cutting blade 46 can be effectively avoided, and the quality and efficiency of the edge grinding of the plate 2 can be improved.

[0038] like Figure 9 As shown, in some embodiments, the polishing mechanism further includes a polishing roller 45. The two ends of the polishing roller 45 are respectively provided with connecting end plates 44, and the two connecting end plates 44 are welded and fixed to the connecting plate 43, and the polishing roller 45 is axially connected to the connecting end plates 44, which can ensure that the polishing roller 45 can rotate smoothly. In order to realize the rotation of the polishing roller 45, the polishing roller 45 is transmission-connected to the second motor 42, thereby realizing efficient and uniform polishing operation.

[0039] In particular, the polishing roller 45 includes a connecting shaft 451, two grinding sections 452 and a polishing section 453. The grinding section 452 and the polishing section 453 are respectively arranged on the outside of the connecting shaft 451. The two grinding sections 452 are respectively arranged on both sides of the polishing section 453, and they are configured to grind the edge portion of the plate 2.

[0040] like Figures 3-5 As shown, in some embodiments, two side pressure assemblies 5 are provided, and the two side pressure assemblies 5 are respectively provided at the two side edges of the plate 2. Specifically, each side pressure assembly 5 includes a telescopic rod 51, a connecting vertical plate 52 and a pressure block 53. Among them, one end of the telescopic rod 51 is connected to the inner side of the fixed frame 11, and the other end is connected to the connecting vertical plate 52.

The upper pressure roller 33 is axially connected to these two fixed side plates 34, so as to ensure the stability and accuracy of the upper pressure roller 33 during rotation.

[0042] As Figure 1 and Figure 2 As shown, in some embodiments, a conveying assembly 6 is specifically provided inside the support assembly 1. The conveying assembly 6 is configured below the upper pressure roller assembly 3. Specifically, it is located in the lower space of the upper pressure roller assembly 3.
