Description

Technical Field

[0001] This utility model relates to the field of edge coating equipment for sheet metal, specifically to a power pressure beam edge coating machine suitable for soft sheet metal. Background Technology

[0002] Currently, edge-sealing machines for boards are used to coat and seal the sides of boards, such as the "Fully Automatic Digital Edge-Sealing Machine and its Edge-Sealing Process" in Chinese Utility Model Patent Publication No. CN110576497B and the "Edge Coating Sanding Machine" in Chinese Invention Patent Publication No. CN110548662B. These edge-sealing machines are equipped with a lower conveyor chain device, which includes a conveyor chain support rail and a conveyor chain assembly. The conveyor chain assembly includes a roller chain and chain blocks, with the chain blocks mounted on the links of the roller chain. The chain blocks are used to contact the underside of the board, and the chain blocks convey the board through friction. The chain blocks at the top of the conveyor chain assembly are supported and guided by the conveyor chain support rail. To prevent slippage between the board and the conveyor chain assembly, the edge-sealing machine also includes a pressure beam assembly, which includes a pressure beam and a driven pressure roller. The driven pressure roller moves along the board... The conveying direction of the material is arranged in an array. The driven pressure roller is rotatably connected to the bottom of the pressure beam. The driven pressure roller is a rubber wheel. When the pressure beam is lowered, the driven pressure roller presses on the top of the board. The driven pressure roller undergoes a small-amplitude elastic deformation. The above-mentioned lower conveyor chain device and pressure beam assembly are existing technologies. For example, you can refer to the following patents: Chinese Utility Model Patent Publication No. CN215549472U "An integrated production line for board edge banding, roller coating and sanding", Chinese Invention Patent Application Publication No. CN118107036A "A three-rail conveyor table mechanism for conveying edge banding machine", Chinese Utility Model Patent Publication No. CN206306223U "Board conveying device for edge banding machine", and Chinese Invention Patent Application Publication No. CN108381729A "A straight edge banding device for wood". Existing edge-coating machines for wood panels are designed for coating wood panels, which are generally quite hard. However, with changing market demands, there is a need to coat and seal the sides of some softer panels (such as fireproof rock wool boards). However, some problems have arisen during production. Because existing pressure beam assemblies are designed for harder wood panels, when processing softer panels, the small contact area between the driven pressure roller and the panel results in high pressure, causing continuous pits and grooves to form on the surface of the soft panel, significantly affecting product quality. Raising the pressure beam can reduce the pressure of the driven pressure roller on the soft panel, but because the feed end of the edge-coating machine requires cutting and smoothing the sides of the soft panel, the reduced pressure from the driven pressure roller makes the panel prone to shifting at the feed end, leading to a significantly increased scrap rate. Summary of the Invention

Detailed Implementation

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] This utility model relates to a power-pressed edge-coating machine suitable for soft sheet materials, such as... Figures 1 to 4 As shown, it includes a lower conveyor chain device 2 and a pressure beam assembly 3, such as Figure 5 As shown, the lower conveyor chain device 2 is provided with a lower conveyor chain assembly 22 for contacting the plate 99. The lower conveyor chain device 2 is provided with a conveyor chain support rail 21, which is located on the lower side of the upper part of the conveyor chain assembly 22, as shown. Figure 3 As shown, the pressure beam assembly 3 is correspondingly disposed on the upper side of the conveyor chain assembly 22. The pressure beam assembly 3 includes a pressure beam 31 and a driven pressure roller 32. The driven pressure roller 32 is rotatably disposed at the bottom of the pressure beam 31. The driven pressure roller 32 is arranged along the conveying direction of the conveyor chain assembly 22. The conveyor chain assembly 22 conveys the plate 99 from right to left, that is to say, the driven pressure roller 32 is arranged in the left and right direction. The lower conveyor chain device 2 and the pressure beam assembly 3 are existing technologies, so they will not be described in detail here. For example, you can refer to the following patents: "An integrated production line for edge banding, roller coating and sanding of board" with Chinese Utility Model Patent Publication No. CN215549472U; "A three-rail conveyor table mechanism for conveying edge banding machine" with Chinese Invention Patent Application Publication No. CN118107036A; "Board conveying device for edge banding machine" with Chinese Utility Model Patent Publication No. CN206306223U; and "A straight edge banding device for wood" with Chinese Invention Patent Application Publication No. CN108381729A.

[0025] like Figures 1 to 5 As shown, the power pressure beam edge coating machine for soft boards of this utility model also includes a conveyor belt device 4 at the feeding end, such as... Figures 7 to 10As shown, the feed end conveyor belt device 4 includes a support beam 42, a conveyor belt motor assembly 43, and an upper conveyor belt 41 for contacting the plate 99. The upper conveyor belt 41 is mounted on the support beam 42, and the conveyor belt motor assembly 43 is mounted on the support beam 42. The conveyor belt motor assembly 43 drives the upper conveyor belt 41 to rotate. Figure 3 and Figure 5 As shown, the upper conveyor belt 41 is correspondingly located on the upper side of the conveyor chain assembly 22, as... Figure 1 and Figure 3 As shown, the pressure beam assembly 3 is located in front of the conveying direction of the upper conveyor belt 41 and the conveying chain assembly 22. The conveying direction of the conveying chain assembly 22 is from right to left. Therefore, the pressure beam assembly 3 is located on the left side of the upper conveyor belt 41. In order to make the edge coating machine suitable for processing shorter plates 99 in the left and right directions, the right end of the pressure beam 31 should be set close to the left end of the upper conveyor belt 41.

[0026] The following is a brief explanation of the working principle of the power pressure beam edge coating machine for soft boards of this utility model: The board 99 is moved from right to left between the upper right end of the conveyor chain assembly 22 and the lower right end of the upper conveyor belt 41, as follows: Figure 5 As shown, since the height of the gap between the upper part of the conveyor chain assembly 22 and the lower part of the upper conveyor belt 41 is slightly less than the thickness of the plate 99, the synergistic squeezing action of the conveyor chain assembly 22 and the upper conveyor belt 41 (the plate 99 is slightly elastically concave) ensures that the upper surface of the plate 99 is in good contact with the upper conveyor belt 41, and the lower surface of the plate 99 is also in good contact with the conveyor chain assembly 22. The feed end conveyor belt device 4 acts as a pressure beam for driving force. The upper part of the conveyor chain assembly 22 and the lower part of the upper conveyor belt 41 move to the left at the same speed, which can drive the plate 99 to move horizontally to the left. Figure 4As shown, from right to left, the feed end of the edge coating machine is equipped with an edge trimming device 7 and a side coating assembly 8 for the board material. The edge trimming device 7 and the side coating assembly 8 are existing technologies. They are located behind the upper conveyor belt 41. The edge trimming device 7 includes a cutter disc that rotates around a vertical axis, allowing the outer circumference of the cutter disc to cut the side (i.e., the rear side) of the board material 99 to be coated. Then, the side coating assembly 8 sprays paint onto the rear side of the board material 99. For an example of the side coating assembly 8, refer to Chinese invention patent application publication number CN120133031A, "A fireproof board edge coating system and paint adjustment method." In this process, the upper conveyor belt 41 can be pressed into the board material 99 to a greater depth. The shallow contact area between the upper conveyor belt 41 and the upper surface of the plate 99 results in a larger total compressive force exerted on the lower part of the upper conveyor belt 41 on the plate 99. This allows the plate 99 to be well positioned relative to the conveyor chain assembly 22, preventing displacement of the plate 99 relative to the conveyor chain assembly 22, which could lead to incorrect cutting depth on the rear side of the plate 99 or poor painting on the rear side of the plate 99. Furthermore, since the upper conveyor belt 41 and the plate 99 are in integral surface contact, the pressure is relatively low, making it less likely for pits to form on the upper surface of the plate 99. Because the conveyor belt motor assembly 43 drives the upper conveyor belt 41, the upper and lower surfaces of the plate 99 are not subjected to lateral pulling forces, preventing damage to the plate 99 and facilitating the smooth transfer of the plate 99. Then, the left end of plate 99 first leaves the upper conveyor belt 41, and then the left end of plate 99 reaches between the driven pressure roller 32 and the conveyor chain assembly 22. Only then does the right end of plate 99 leave the upper conveyor belt 41. Plate 99 then transitions to the underside of the pressure beam 31, causing the driven pressure roller 32 to rotate. The pressure exerted by the driven pressure roller 32 on plate 99 can be set to be relatively light; that is, the pressure beam lifting mechanism 9 moves the pressure beam 31 upward to a suitable position, allowing the driven pressure roller 32 to lightly press on the top of plate 99, avoiding the driven pressure roller 32 creating a dent on the top of plate 99. The pressure beam lifting mechanism 9 is existing technology; for example... Referring to the Chinese invention patent application publication number CN108381729A, "A Straight Edge Sealing Device for Wood", a drying device is arranged on the bed 1 of the edge coating machine and behind the pressure beam 31. The drying device can refer to the Chinese invention patent publication number CN110548662B, "An Edge Coating Sanding Machine". Since the positioning requirements of the board 99 can be reduced after the edge trimming and coating process is completed, the slight displacement of the board 99 relative to the conveyor chain assembly 22 between the pressure beam 31 and the conveyor chain assembly 22 will not affect the product quality of the board 99.As can be seen from the above, the combination of the structure of the driven pressure roller 32 pressing down on the plate 99 and the structure of the upper conveyor belt 41 pressing down on the plate 99 in the coating machine of this utility model can relatively improve the quality of the soft plate 99 product. Moreover, it avoids the need to set the upper conveyor belt 41 to be arranged on the upper part of the entire conveyor chain assembly 22. That is to say, it avoids the need to set a long upper conveyor belt 41, thus avoiding a significant increase in cost. Furthermore, the upper conveyor belt 41, after a long period of use, will loosen and grow more, resulting in more frequent adjustment or replacement of the upper conveyor belt 41. In addition, if any part of the long upper conveyor belt 41 breaks, the entire belt needs to be replaced, and replacing the long upper conveyor belt 41 will lead to excessively high maintenance costs.

[0027] Furthermore, such as Figures 7 to 9 As shown, the upper conveyor belt 41 surrounds the outside of the support beam 42. Corner support wheels 421 are respectively provided at the four corners of the support beam 42. That is, the support beam 42 is rectangular, and there are four corner support wheels 421. The support beam 42 can be made of aluminum profile. Rotating support plates are installed at both ends of the support beam 42. The corner support wheels 421 are rotatably connected to the aforementioned rotating support plates. Two corner support wheels 421 are located on the left outer side of the support beam 42, and the other two corner support wheels 421 are located on the right outer side of the support beam 42. The upper conveyor belt 41 is wound around the corner support wheels 421. Through the above arrangement, even when the outer diameter of the corner support wheels 421 is relatively small, the upper conveyor belt 41 can still bypass the corners of the support beam 42. Furthermore, as... Figure 3 As shown, since the outer diameter of the corner support wheel 421 corresponding to the lower left corner of the support beam 42 can be set to be smaller, when the corner support wheel 421 corresponding to the lower left corner of the support beam 42 is set close to the driven pressure wheel 32 at the rightmost end of the pressure beam 31, the distance from the lower end of the driven pressure wheel 32 at the rightmost end to the lower end of the corner support wheel 421 corresponding to the lower left corner of the support beam 42 is smaller, which can shorten the pressure void area of ​​the plate 99, so that the plate 99 with a shorter length in the left and right direction can also smoothly transition from the lower part of the upper conveyor belt 41 to the pressure beam assembly 3.

[0028] Furthermore, such as Figure 5 and Figure 9As shown, a back support wheel 47 is rotatably connected to the bottom of the support beam 42. That is to say, the rotation axis of the back support wheel 47 is fixed relative to the support beam 42. The rotation axis of the back support wheel 47 is along the front-back direction. The back support wheel 47 is attached to the inner side (i.e., the upper side) of the lower part of the upper conveyor belt 41. The back support wheel 47 can be made of steel. The back support wheel 47 is arranged along the conveying direction of the upper conveyor belt 41. The direction of the conveying plate 99 of the upper conveyor belt 41 is from right to left. That is to say, the back support wheel 47 is arranged in the left-right direction. Thus, the arranged back support wheel 47 can support the lower part of the upper conveyor belt 41, so that the lower part of the upper conveyor belt 41 can maintain a good straight shape. This is beneficial for the lower part of the upper conveyor belt 41 to be attached to the plate 99 as a whole.

[0029] Furthermore, such as Figure 10 As shown, a positioning groove 471 is formed on the back support wheel 47, and an inner ridge 4101 is formed on the inner side of the upper conveyor belt 41. The inner ridge 4101 is adapted to connect with the positioning groove 471, so that the back support wheel 47 can position the lower part of the upper conveyor belt 41 in the front-back direction, avoiding the lower part of the upper conveyor belt 41 from shaking back and forth during operation, which would cause the plate 99 to shift, or cause the upper and lower parts of the plate 99 to be pulled back and forth.

[0030] Furthermore, such as Figure 9 As shown, rollers 423 are distributed on the lower side of the support beam 42. For example, there can be two rollers 423. The rollers 423 are close to the outer side of the lower part of the upper conveyor belt 41. The position of the rollers 423 is higher than that of the back support roller 47, thus avoiding contact between the rollers 423 and the plate 99. Therefore, the lower part of the upper conveyor belt 41 partially bypasses the rollers 423, and the rollers 423 support the upper conveyor belt 41 from below, preventing the lower part of the upper conveyor belt 41 from sagging excessively due to gravity. Figure 10 As shown, a groove shell 420 is installed at the bottom of the support beam 42, and the support roller 423 and back support roller 47 are located inside the groove shell 420. Figures 7 to 9As shown, the feed end conveyor belt device 4 includes a drive pulley 431, a motor base 44, a hanger 45, and a tensioning rod 46. The conveyor belt motor assembly 43 is a geared motor. The drive pulley 431 is mounted on the output shaft of the conveyor belt motor assembly 43. The upper part of the upper conveyor belt 41 is wound around the drive pulley 431 via a turning support wheel 422, meaning that the turning support wheel 422 contacts the outer side of the upper part of the upper conveyor belt 41. The conveyor belt motor assembly 43 is mounted on the motor base. On the upper part of the suspension bracket 45, a connecting support beam 42 is installed at the lower part. The upper end of the tensioning rod 46 is attached to the suspension bracket 45, and the lower part of the tensioning rod 46 is screwed to the motor base 44. The motor base 44 is connected to the suspension bracket 45 by bolts. An elongated hole extending in the vertical direction is formed on the motor base 44. The bolt passes through the elongated hole, and the bolt is loosened. Then, the tensioning rod 46 is rotated, which can drive the motor base 44 to move upward, causing the drive pulley 431 to move upward and tighten the upper conveyor belt 41. When the conveyor belt motor assembly 43 is running, the drive pulley 431 rotates, driving the upper conveyor belt 41 to rotate.

[0031] like Figure 10 As shown, the upper conveyor belt 41 may include an inner belt layer 411 and an outer belt layer 412. The outer belt layer 412 is bonded to the inner belt layer 411. The outer belt layer 412 is used to contact the plate 99. The inner belt layer 411 is used to contact the back support wheel 47, the corner support wheel 421, and the drive pulley 431. The outer belt layer 412 may be made of softer rubber. Therefore, when the outer belt layer 412 is pressed on the plate 99, the outer belt layer 412 can be elastically deformed more significantly. When there is a small wave-like unevenness on the surface of the plate 99, the elastic depression deformation of the outer belt layer 412 can serve as compensation, so that the lower part of the upper conveyor belt 41 can make good overall surface contact with the plate 99. Furthermore, the front and rear edges of the outer belt layer 412 are easy to elastically deform, which can further prevent the upper conveyor belt 41 from pressing pits into the plate 99.

[0032] Furthermore, such as Figures 3 to 5 As shown, the edge coating machine of this utility model also includes a conveyor belt lifting mechanism 5. The conveyor belt lifting mechanism 5 includes a conveyor belt lifting motor assembly 51, a conveyor belt lifting screw 52, ​​a fixing screw block 53, and a lifting seat 54. The lifting seat 54 is connected to the support beam 42. The conveyor belt lifting motor assembly 51 is installed on the top of the lifting seat 54. The conveyor belt lifting screw 52 is rotatably connected to the lifting seat 54. The rotation axis of the conveyor belt lifting screw 52 is vertically set. The conveyor belt lifting motor assembly 51 drives the conveyor belt lifting screw 52 to rotate. The conveyor belt lifting motor assembly 51 includes a motor and a worm gear reducer. The worm gear of the worm gear reducer is coaxially installed on the upper end of the conveyor belt lifting screw 52. The lower part of the conveyor belt lifting screw 52 is screwed to the fixing screw block 53. A support column 11 is installed on the bed 1. The fixing screw block 53 is installed on the upper end of the support column 11. Figure 6As shown, the lifting seat 54 is equipped with a guide rod 541, which is parallel to the conveyor belt lifting screw 52. The guide rod 541 is adapted to pass through the fixed screw block 53, so the guide rod 541 can move up and down relative to the fixed screw block 53. When the conveyor belt lifting motor assembly 51 is running, the conveyor belt lifting motor assembly 51 drives the conveyor belt lifting screw 52 to rotate, thereby causing the conveyor belt lifting screw 52 to move up and down relative to the fixed screw block 53. This allows the feed end conveyor belt device 4 to be raised and lowered to form a suitable compression on the plate 99 and to adapt to plates 99 of different thicknesses.
