Description

Technical Field

[0001] The present application relates to the field of sheet metal processing equipment, and in particular to a hot pressing device for angled sheets. Background Art

[0002] With the development of society, various types of panels are widely used. When ordinary flat panels are paved and encounter wall corners, stair steps, or need to be shaped, they can only be cut and then spliced ​​into shape. This processing method will inevitably cause splicing gaps. Over time, dust and other dirt will be stuck in the gaps, which are difficult to clean. In addition, the assembly time of multiple pieces will also be relatively long. Therefore, the panels are generally folded at the corners, and the panels are processed into L-shaped or V-shaped shapes, from flat panels to angled panels to meet usage needs, thereby reducing the existence of gaps and achieving ideal usage effects.

[0003] After the current board is processed by corner bending, it is still necessary to go through processes such as gluing and pressing. When gluing, an adhesive is applied on the board surface of the board, and then the boards are stacked so that the boards are bonded to each other through the adhesive, and then the corner boards are pressed. The current pressing method is to first apply pressure to the same corner side of the stacked and bonded corner boards, tightly press the same corner sides of the stacked and bonded corner boards together, and then apply pressure to the other corner side of the stacked and bonded corner boards, thereby completing the pressing of the corner boards. However, during the first pressing process, the stacked corner boards may be offset, so that the corner sides of the corner boards that have not been pressed together may be separated from each other. During the second pressing, the corner sides of the corner boards that have been fixed are prone to separation, thereby affecting the quality of the finished product after pressing. If pressing is performed multiple times, the process will be increased, and the shape of the board will be easily damaged, further affecting the quality of the finished product.

[0038] When the plate needs to be hot pressed, the plate can be placed on the first pressure plate 21 and the second pressure plate 41, and the first pressure plate 21, the second pressure plate 41 and the pressure plate group are heated respectively, so that the pressing drive member 31 drives the lower pressure seat 32 to press down, so that the pressure plate group approaches and presses the plate, and the plate is pressed tightly, thereby hot pressing the plate.

[0039] The angle between the pressure surface of the first pressure plate 21 and the pressure surface of the second pressure plate 41 is greater than 0° and less than 180°. In this embodiment, the angle between the pressure surface of the first pressure plate 21 and the pressure surface of the second pressure plate 41 is 90°, and the first pressure plate 21 and the second pressure plate 41 are perpendicular to each other.

[0040] When the angled sheet material needs to be pressed, one angled side of the angled sheet material can be placed on the first pressure plate 21 and the other angled side can be placed on the second pressure plate 41. The first pressure plate 21, the second pressure plate 41 and the pressure plate group are heated respectively, so that the pressing drive member 31 drives the lower pressure seat 32 and the pressure plate group to press downward toward the angled sheet material, and the angled sheet material is pressed against the pressure surfaces of the first pressure plate 21 and the second pressure plate 41 at the same time, so that the angled sheet material can be hot pressed. At this time, the two angled sides of the stacked and bonded angled sheets are in a pressed state, so the angled sheets are not easy to separate, which can improve the quality of the finished product after the angled sheets are pressed.

[0041] A folded press frame 35 is provided between the lower press seat 32 and the press plate group. The folded press frame 35 is installed on the side of the lower press seat 32 away from the pressing drive member 31. The press plate group includes a first press plate 33 and a second press plate 34. The first press plate 33 and the second press plate 34 are respectively installed on the adjacent two side walls of the folded press frame 35. The extension direction of the first press plate 33 is consistent with the extension direction of the first pressure plate 21. The extension direction of the first press plate 33 is consistent with the extension direction of the second pressure plate 34. The pressing surface of the first press plate 33 is parallel to the pressure surface of the first pressure plate 21. The pressing surface of the second pressing plate 34 is parallel to the pressure surface of the second pressure plate 41, the side wall of the first pressing plate 33 abuts against the side wall of the second pressing plate 34, and the angle between the pressing surface of the first pressing plate 33 and the pressing surface of the second pressing plate 34 is greater than 180° and less than 360°. In this embodiment, the angle between the pressing surface of the first pressing plate 33 and the pressing surface of the second pressing plate 34 is 270°, the pressing surface of the first pressing plate 33 and the pressing surface of the second pressing plate 34 are perpendicular to each other, and the first pressing plate 33 and the second pressing plate 34 are respectively connected to the external heat source.

[0042] When the angled sheet material needs to be pressed, one side of the angled sheet material is placed on the first pressure plate 21 and the other side is placed on the second pressure plate 41, and the first pressure plate 33, the second pressure plate 34, the first pressure plate 21 and the second pressure plate 41 are heated, so that the pressing drive member 31 drives the lower pressure seat 32 to move downward, so that the first pressure plate 33 is pressed against the first pressure plate 21, and the second pressure plate 34 is pressed against the second pressure plate 41, until the angled sheet material is pressed tightly against the first pressure plate 21 and the second pressure plate 41, so that the angled sheet material can be hot pressed. Since the two adjacent angled sides of the angled sheet material are pressed at the same time, it is not easy for the angled sides of the stacked angled sheets to separate from each other, thereby improving the quality of the finished product after the angled sheets are pressed.

[0043] Reference Figure 1 and Figure 3 The side wall of the corner pressing frame 35 is rotatably connected to the first winding roller 36, and the pressing surface of the first pressure plate 33 is provided with a first winding belt 37. The side walls of the first winding belt 37 are respectively pressed against the pressing surface of the first pressure plate 33 and the pressing surface of the second pressure plate 34. The first winding belt 37 is wound on the side wall of the first winding roller 36, and the first winding belt 37 is in a taut state.

[0044] When the angled sheet material is being pressed, the first winding belt 37 can protect the first pressing plate 33 and the second pressing plate 34, so that the angled sheet material does not directly contact the first pressing plate 33 and the second pressing plate 34, thereby reducing the adhesive sticking to the pressing surface of the first pressing plate 33 and the pressing surface of the second pressing plate 34 during the hot pressing process, reducing the cleaning cost, and reducing the impact on other angled sheets that are about to be pressed.

[0045] The end of the first winding roller 36 is connected to a first ratchet 39 , and the side wall of the angle pressing frame 35 is rotatably connected to a first pawl 38 , which is engaged with the first ratchet 39 .

[0046] The first pawl 38 and the first ratchet wheel 39 are engaged with each other to keep the first winding belt 37 taut and less likely to become loose, thereby making the first winding belt 37 less likely to wrinkle, reducing the occurrence of wrinkle marks when the angled plates are pressed together and improving the quality of the finished product.

[0047] Reference Figure 1 and Figure 2 A guide column 12 is fixed to the bottom of the upper frame 3, and the extension direction of the guide column 12 is consistent with the driving direction of the pressing drive member 31. The guide column 12 passes through the lower pressure seat 32, and the guide column 12 and the lower pressure seat 32 are in a sliding fit. The lower pressure seat 32 is in a sliding fit with the upper frame 3 by sliding fit with the guide column 12.

[0048] The guide column 12 can guide and limit the lower press seat 32, so that the lower press seat 32 can move along the driving direction of the pressing drive member 31, reduce the deviation of the lower press seat 32, improve the pressing accuracy, and improve the quality of the finished product.

[0049] An abutment seat 13 is disposed on the side wall of the support frame 11 , and one end of the guide column 12 away from the upper frame 3 is connected to the top of the abutment seat 13 .

[0050] The abutment seat 13 can block the pressing seat 32 to reduce the situation where the pressing seat 32 is over-pressed and thus separated from the guide column 12 .

[0051] Reference Figure 2 and Figure 4 A rotating roller 22 is arranged between the first pressure plate 21 and the pressure seat 2, and the rotating roller 22 is rotatably connected to the pressure seat 2. The side of the pressure seat 2 facing away from the lower frame 1 is rotatably connected with a conveying roller 23. A conveying driving member 24 is arranged on the side wall of the pressure seat 2. The conveying driving member 24 is a servo motor. The output end of the conveying driving member 24 is connected to the conveying roller 23 through a sprocket chain transmission. The conveying driving member 24 can drive the conveying roller 23 to rotate. A conveyor belt 25 is arranged on the side of the first pressure plate 21 facing away from the pressure seat 2. The conveyor belt 25 is tightly attached to the pressure surface of the first pressure plate 21. The conveyor belt 25 surrounds the pressure seat 2, the conveying roller 23 and the rotating roller 22, and the conveyor belt 25 is in a taut state.

[0052] When the angled sheet needs to be pressed, the angled sheet is placed from the input end of the lower frame 1 onto the conveyor belt 25, so that the conveying drive 24 drives the conveying roller 23 to rotate, and the conveying roller 23 drives the conveyor belt 25 to move, so that the angled sheet is moved as a whole to the first pressure plate 21 for hot pressing. There is no need for the staff to push or move the angled sheet to the first pressure plate 21, which saves time and effort.

[0053] The side wall of the conveyor roller 23 is provided with a bidirectional thread. When the conveyor driving member 24 drives the conveyor roller 23 to rotate, the conveyor roller 23 drives the conveyor belt 25 to move. At the same time, the bidirectional thread on the conveyor roller 23 can make the conveyor belt 25 unfold to both sides, which can reduce the overlap of the conveyor belt 25 during the movement, thereby reducing the wrinkles of the angled sheet when pressing.

[0054] The side wall of the pressure-bearing seat 2 is slidably connected with a sliding rod 26, and the side wall of the pressure-bearing seat 2 is provided with an adjusting driving member 27. The adjusting driving member 27 is a cylinder, and the output end of the adjusting driving member 27 is connected to the sliding rod 26. The adjusting driving member 27 can drive the sliding rod 26 to slide. The end of the sliding rod 26 is rotatably connected with an adjusting roller 28. The extension direction of the adjusting roller 28 is consistent with the extension direction of the conveying roller 23, and the conveying belt 25 surrounds the adjusting roller 28.

[0055] When the conveyor belt 25 becomes loose, the adjusting drive member 27 can drive the sliding rod 26 to slide, driving the adjusting roller 28 to move, so that the adjusting roller 28 tightens the conveyor belt 25, thereby adjusting the conveyor belt 25 to a taut state, reducing wrinkles, reducing the appearance of wrinkle marks on the corner plates after pressing, reducing the scrap rate, and reducing the slippage of the conveyor belt 25.

[0056] Reference Figure 1 and Figure 2 A fixed seat 14 is fixed on the top of the lower frame 1, and the bottom of the pressure-bearing seat 2 is rotatably connected to the fixed seat 14. A rotating driving member 15 is provided on the top of the lower frame 1. The rotating driving member 15 is a hydraulic cylinder. The rotating driving member 15 is rotatably connected to the lower frame 1, and the output end of the rotating driving member 15 is rotatably connected to the bottom of the pressure-bearing seat 2.

[0057] When the angled sheet needs to be pressed, the rotating driving member 15 can drive the pressure seat 2 to rotate, driving the first pressure plate 21 to rotate, so that the first pressure plate 21 is parallel to the ground or nearly parallel to the ground. In this state, one of the angled sides of the angled sheet can be placed on the conveyor belt 25, and the other angled side of the angled sheet is facing the second pressure plate 41, and the conveying roller 23 is driven to move the angled sheet completely onto the conveyor belt 25. Then, the rotating driving member 15 can drive the pressure seat 2 to rotate, so that the first pressure plate 21 is parallel to the first pressure plate 33, and the second pressure plate 41 is parallel to the first pressure plate 33. Parallel to the second pressure plate 34, the angled sheet material slides toward the second pressure plate 41 under the action of gravity until it abuts against the pressure surface of the second pressure plate 41. At this time, the pressing drive member 31 can drive the first pressure plate 33 and the second pressure plate 34 to press the angled sheet material onto the first pressure plate 21 and the second pressure plate 41 for hot pressing. The rotating drive member 15 can reduce the contact between the angled sheet material and the second pressure plate 41 during the transmission process, thereby reducing the wear between the angled sheet material and the second pressure plate 41, reducing the scrap rate, improving the quality of the finished product, and at the same time reducing the power consumption of the transmission drive member 24.

[0058] After the angled plate is pressed together, the rotating driving member 15 can drive the pressure seat 2 to rotate again, so that the pressure surface of the first pressure plate 21 is parallel or nearly parallel to the ground, and the conveying driving member 24 drives the conveying roller 23 to rotate, driving the conveyor belt 25 to move, and moving the angled plate out of the first pressure plate 21.

[0059] Reference Figure 1 and Figure 2 A limit seat 16 is provided on the top of the lower frame 1, and a baffle 161 is provided on the top of the limit seat 16. When the pressure surface of the first pressure plate 21 is parallel to the pressing surface of the first pressure plate 33, the baffle 161 abuts against the side wall of the pressure seat 2, and the baffle 161 can support and limit the pressure seat 2.

[0060] After the angled sheet material is completely moved onto the conveyor belt 25, during the process of the rotating driving member 15 driving the pressure seat 2 to rotate, when the pressure surface of the first pressure plate 21 is parallel to the pressing surface of the first pressure plate 33, the side wall of the pressure seat 2 abuts against the baffle 161, and the baffle 161 can block the pressure seat 2 so that the pressure seat 2 no longer rotates, thereby limiting the pressure seat 2, making the pressure surface of the first pressure plate 21 parallel to the pressing surface of the first pressure plate 33, and also making the pressure surface of the second pressure plate 41 parallel to the pressing surface of the second pressure plate 34, so that the first pressure plate 33 and the second pressure plate 34 can be accurately pressed on the angle of the angled sheet material, reducing the pressure deviation and improving the pressing quality.

[0061] Reference Figure 2A top-connecting frame 17 is fixed on the top of the lower frame 1. When the pressure surface of the first pressure plate 21 is parallel to the pressing surface of the first pressure plate 33, the top side of the top-connecting frame 17 abuts against the bottom side of the pressure seat 2, and the top-connecting frame 17 can support the pressure seat 2.

[0062] After the angled plate is completely moved onto the conveyor belt 25, during the process of the rotating driving member 15 driving the pressure seat 2 to rotate, when the pressure surface of the first pressure plate 21 is parallel to the pressing surface of the first pressure plate 33, the top frame 17 abuts against the bottom side of the pressure seat 2, making it difficult for the pressure seat 2 to continue to rotate, thereby limiting the pressure seat 2. Further, the first pressure plate 33 and the second pressure plate 34 can be accurately pressed on the angle of the angled plate, thereby reducing the situation where the first pressure plate 33 and the second pressure plate 34 are pressed off due to errors in the rotation angle of the pressure seat 2, thereby improving the pressing quality.

[0063] Reference Figure 1 and Figure 2 A limiting rod 18 is fixed on the top of the lower frame 1, the limiting rod 18 is close to the rotating drive member 15, the fixed seat 14 is located between the limiting seat 16 and the limiting rod 18, the pressure surface of the first pressure plate 21 is parallel or nearly parallel to the ground, the top surface of the limiting rod 18 abuts against the bottom side of the pressure seat 2, and the limiting rod 18 supports the pressure seat 2.

[0064] During the process of the rotating driving member 15 driving the pressure seat 2 to rotate, when the pressure surface of the first pressure plate 21 is parallel or nearly parallel to the ground, the limit rod 18 abuts against the pressure seat 2, which can prevent the pressure seat 2 from continuing to rotate downward, thereby reducing the situation where the pressure seat 2 rotates excessively and causes the angled plate to slide out of the first pressure plate 21.

[0065] Reference Figure 1 and Figure 5 A connecting seat 4 is provided on the side of the pressure-bearing seat 2 facing away from the lower frame 1, a second pressure-bearing plate 41 is fixed on the side wall of the connecting seat 4, a second winding roller 42 is rotatably connected to the side wall of the connecting seat 4, a second winding belt 43 is provided on the side of the second pressure-bearing plate 41 facing away from the connecting seat 4, the side wall of the second winding belt 43 is tightly attached to the pressure surface of the second pressure-bearing plate 41, the second winding belt 43 is wound on the side wall of the second winding roller 42, and the second winding belt 43 is in a tensioned state.

[0066] When the angled sheet moves toward the second pressure plate 41, the second winding belt 43 can block the angled sheet so that the angled sheet does not directly contact the pressure surface of the second pressure plate 41, thereby reducing the adhesive sticking to the second pressure plate 41 during the hot pressing process and reducing cleaning costs.

[0067] The end of the second winding roller 42 is connected to a second ratchet 44 , and the side wall of the connecting seat 4 is rotatably connected to a second pawl 45 , which is engaged with the second ratchet 44 .

[0068] The mutual clamping between the second pawl 45 and the second ratchet wheel 44 can keep the second winding roller 42 in a taut state and prevent it from loosening, thereby reducing possible wrinkles on the first winding belt 37 and wrinkle marks on the corner plate during the lamination process, thereby improving the quality of the finished product.

[0069] Reference Figure 2 and Figure 6 A slide rail 29 is provided on the side of the pressure-bearing seat 2 facing away from the lower frame 1, and the extension direction of the slide rail 29 is perpendicular to the extension direction of the second pressure-bearing seat 2. A slider 46 is fixed on the side of the connecting seat 4 close to the pressure-bearing seat 2, and the slider 46 is slidingly connected to the slide rail 29. The connecting seat 4 can slide on the side of the pressure-bearing seat 2 facing away from the lower frame 1 through the slider 46 and the slide rail 29. A mounting seat 47 is provided on the side of the pressure-bearing seat 2 facing away from the lower frame 1, and the side wall of the mounting seat 47 is rotatably connected with a sliding drive member 48. The sliding drive member 48 is a hydraulic cylinder, and the output end of the sliding drive member 48 is rotatably connected to the side of the connecting seat 4 facing away from the second pressure plate 41. The sliding drive member 48 can drive the connecting seat 4 to slide along the extension direction of the slide rail 29.

[0070] After the corner plate is pressed together, the rotating drive member 15 drives the pressure seat 2 to rotate, so that the first pressure plate 21 is parallel or nearly parallel to the ground, and the sliding drive member 48 drives the connecting seat 4 to slide, so that the second pressure plate 41 is away from the first pressure plate 21 and the corner plate. At this time, the transmission drive member 24 can be driven to transport the corner plate away from the first pressure plate 21 for unloading. During the unloading process, the contact between the corner plate and the second winding belt 43 or the second pressure plate 41 can be reduced, thereby reducing the wear of the corner plate and improving the quality of the finished product of the corner plate.

[0071] The implementation principle of a hot pressing device for angled plates in the embodiment of the present application is as follows: when the angled plates need to be pressed, the rotating driving member 15 can drive the pressure seat 2 to rotate, driving the first pressure plate 21 to rotate, so that the first pressure plate 21 is parallel or nearly parallel to the ground, the stacked angled plates are placed on the conveyor belt 25, and the conveying driving member 24 drives the conveyor belt 25 to move the angled plates completely to the conveyor belt 25, so that the rotating driving member 15 drives the pressure seat 2 to rotate, so that the pressing surface of the first pressure plate 33 is parallel to the pressure surface of the first pressure plate 21, and the first pressure plate 21 is pressed. The pressing surface of the second pressure plate 34 is made parallel to the pressure surface of the second pressure plate 41, and the first pressure plate 21, the second pressure plate 41, the first pressure plate 33 and the second pressure plate 34 are heated respectively, so that the pressing driving member 31 drives the first pressure plate 33 and the second pressure plate 34 to press the angled sheet material, and the angled sheet material is pressed tightly against the pressure surface of the first pressure plate 21 and the pressure surface of the second pressure plate 41, thereby hot pressing the angled sheet material. At this time, the two angled sides of the stacked and bonded angled sheet materials are in a pressed state, so the angled sheets are not easy to separate, which can improve the quality of the finished product after the angled sheets are pressed.

[0072] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
