Description

Technical Field

[0001] This invention relates to the field of sheet metal cutting technology, and in particular to an edge residue removal device for the production of SMC insulation boards. Background Technology

[0002] SMC insulation board is a high-performance composite material mainly composed of unsaturated polyester resin, glass fiber, low-shrinkage additives, and fillers. Due to its high mechanical strength, excellent insulation properties, strong corrosion resistance, good flame retardancy, and low water absorption, SMC insulation board is widely used in various fields such as the power industry, automotive industry, construction industry, shipbuilding industry, and electrical and communications engineering industries.

[0003] When workers cut SMC insulation boards with blades to remove edge residue, burrs and flash can easily form on the cut edges if the blades are not sharp enough or the cutting speed and feed rate are not set properly. Furthermore, cutting with blades can generate heat and cause localized deformation of the SMC insulation board, increasing the likelihood of burrs and flash. The breakage of glass fibers and localized melting of resin are the main causes of burrs and flash. However, existing board cutting equipment cannot completely remove burrs and flash, requiring additional manual or mechanical grinding after cutting to ensure product quality. This method is not only time-consuming and labor-intensive but also severely impacts the production efficiency of SMC insulation boards.

[0004] Based on the above, the present invention proposes an edge residue removal device for the production of SMC insulation boards with good deburring effect. Summary of the Invention

Detailed Implementation

[0034] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example

[0035] An edge residue removal device for SMC insulation board production, such as Figures 1-5 As shown, the system includes a frame 1, a placement platform 11, a cutting module 12, a control module 1201, a support frame 13, a mounting frame 14, rollers 15, a connecting frame 16, a first elastic component 17, a cutting tool 18, a motor 19, a blade 110, a telescopic frame 111, and a spatial cam 112. The placement platform 11 is fixedly attached to the top of the frame 1. The support frame 13 is fixedly attached to the rear side of the frame 1. The cutting module 12 is mounted on the right side of the support frame 13, and the control module 1201 is mounted on the left side of the support frame 13. The control module 1201 is electrically connected to the cutting module 12. The mounting frame 14 is fixedly attached to the top of the frame 1. A connecting frame 16 is slidably connected to the front side. Two first elastic components 17 are fixed between the connecting frame 16 and the mounting frame 14. Rollers 15 are rotatably connected to the left and right sides of the front side of the connecting frame 16. A motor 19 is fixedly connected to the lower front side of the mounting frame 14. A motor 19 is also fixedly connected to the upper rear side of the connecting frame 16. A cutting tool 18 is fixedly connected to the output end of the motor 19. A telescopic frame 111 is fixedly connected to the right side of the connecting frame 16. A blade 110 is fixedly connected to the front of the telescopic end of the telescopic frame 111. A spatial cam 112 is fixedly connected to the output end of the upper motor 19. The left side of the telescopic end of the telescopic frame 111 is slidably connected to the spatial cam 112.

[0036] like Figure 4 and Figure 5 As shown, blade 110 is herringbone shaped.

[0037] When workers need to remove edge residue from SMC insulation boards, they can first place the SMC insulation board to be processed in a suitable position on the placement table 11, and then start the cutting module 12 through the control module 1201. The SMC insulation board to be processed is then moved smoothly to the left along the placement table 11. During this process, the cutting machine in the cutting module 12 will remove the edge residue from the SMC insulation board. However, the structural characteristics of the SMC insulation board make it easy for burrs and flash to appear during the cutting process. Therefore, when the worker continues to move the cut SMC insulation board to the left and starts the electric... When the machine is in operation (19), the left end of the SMC insulation plate will first contact and press the roller 15, thereby causing the roller 15, connecting frame 16, blade 110, and upper cutting tool 18 to move upward. The first elastic component 17 will then be compressed. At this time, the roller 15 will adhere to the top of the SMC insulation plate under its own weight and the elastic force of the first elastic component 17, and the blade 110 will adhere to the rear side of the SMC insulation plate. Since the top of the lower cutting tool 18 and the top of the placement platform 11 are on the same horizontal plane, while the bottom of the upper cutting tool 18 and the bottom of the roller 15 are on the same horizontal plane... Since they are on the same horizontal plane, the cutting blades 18 on the upper and lower sides can contact the upper and lower edges of the rear part of the SMC insulation board, respectively. Therefore, when the SMC insulation board moves to the left and contacts the cutting blades 18 and the blades 110, the motor 19 will drive the space cam 112 and the cutting blades 18 on the upper and lower sides to rotate. The rotation of the cutting blades 18 can remove the burrs on the upper and lower edges of the SMC insulation board, while the rotation of the space cam 112 can drive the telescopic frame 111 to extend and retract up and down through its own slide groove. The blades 110 also move up and down and cut the SMC insulation board. The burrs on the back side of the insulation board are removed so that the burrs on the side of the SMC insulation board and the flash on the top and bottom edges can be completely removed immediately after cutting. This not only avoids the need for workers or machinery to perform additional grinding on the SMC insulation board, but also ensures the quality of the cut product. After processing, the cutting module 12 and motor 19 are turned off and the SMC insulation board and edge residue are removed from the placement table 11 or frame 1. The rollers 15 and connecting frame 16 and other components then move downward and reset under their own weight and the elastic force of the first elastic component 17. Example

[0038] Based on Example 1, such as Figure 6 and Figure 7As shown, it also includes a grinding mechanism, which is set on the mounting frame 14. The grinding mechanism includes a grinding column 2, a push frame 21, a spring 22 and a guide block 23. Two guide blocks 23 are fixedly connected to the lower left and right sides of the mounting frame 14 respectively. The push frame 21 is slidably connected between the two guide blocks 23. Two springs 22 are fixedly connected between the push frame 21 and the mounting frame 14. The grinding column 2 is fixedly connected to the left and right sides of the front side of the push frame 21. The grinding column 2 is slidably connected to the mounting frame 14.

[0039] As the worker moves the cut SMC insulation board to the left, the left edge of the SMC insulation board will first contact the front half of the arc surface of the right grinding column 2 and press it backward. The push frame 21 will also move backward, and the spring 22 will be compressed. During this time, the right grinding column 2 can grind away the burrs and flash on the left edge of the SMC insulation board. If the SMC insulation board continues to move to the left, the two grinding columns 2 will remain in close contact with the rear side of the SMC insulation board under the action of the spring 22 and grind it, thus ensuring that the cut surface of the SMC insulation board is smooth. When the SMC insulation board moves to the left and separates from the left grinding column 2, the left grinding column 2 and other components will move forward and reset under the action of the spring 22 and grind away the burrs and flash on the right edge of the SMC insulation board. In this way, the burrs and flash on both sides of the SMC insulation board can be completely removed immediately after cutting, thereby improving the quality of the cut product.

[0040] like Figures 8-10 As shown, it also includes a fixing mechanism, which is set on the placement platform 11. The fixing mechanism includes a placement plate 3, a bracket 31, a sliding frame 32, a pressure block 33, a rotating frame 34, and a pressure roller 35. The placement plate 3 is slidably connected to the top of the placement platform 11. The bracket 31 is fixedly connected to the front side of the placement plate 3. The sliding frame 32 is slidably connected to the upper part of the bracket 31. The left and right sides of the top of the bracket 31 are threaded with screws. The screws are pressed and engaged with the sliding frame 32. The pressure block 33 is slidably connected to the rear side of the sliding frame 32. The rotating frame 34 is rotatably connected to the top of the sliding frame 32. The pressure roller 35 is fixedly connected to the rear side of the rotating frame 34. The pressure roller 35 is pressed and engaged with the pressure block 33.

[0041] like Figure 9 and Figure 10 As shown, the pressure roller 35 is semi-cylindrical in shape.

[0042] Since it is difficult to maintain stability when moving the SMC insulation board to the left by hand, when placing the SMC insulation board, the worker can first place the SMC insulation board in a suitable position on the placement plate 3. At this time, the pressure block 33 presses down on the top of the SMC insulation board by its own weight, while the rotating frame 34 is in an upward flipped state and the pressure roller 35 is not in contact with the pressure block 33. Then, according to the width of the SMC insulation board, the sliding frame 32 and the pressure block 33 and other components are moved back and forth until the pressure block 33 and other components are adjusted to a suitable position. The position of the pressure block 33 is then fixed by the two screws on the left and right. After fixing, the rotating frame 34 can be rotated downwards, thereby driving the pressure roller 35 to rotate clockwise. When the pressure roller 35 rotates clockwise, it contacts and squeezes the pressure block 33, which is then subjected to downward pressure. At this time, the pressure block 33 cooperates with the placement plate 3 to clamp and fix the SMC insulation board. When the worker needs to move the SMC insulation board to the left, the placement plate 3 and the bracket 31 and other components can drive the SMC insulation board to move to the left together. This can fix and guide the SMC insulation board, thereby preventing the SMC insulation board from shifting during cutting and subsequent processing, and affecting the overall processing effect of the device. When it is necessary to remove the SMC insulation board from the placement plate 3, the rotating frame 34 and the pressure roller 35 can be rotated in the opposite direction and reset.

[0043] like Figure 11 and Figure 12 As shown, it also includes a shock absorption mechanism, which is installed on the support frame 13. The shock absorption mechanism includes a mounting plate frame 4, a second elastic component 41, a contact plate 42, and a liquid storage pipe 43. The mounting plate frame 4 is fixed to the front side of the support frame 13. The contact plate 42 is slidably connected to the front side of the mounting plate frame 4. Two second elastic components 41 are fixed between the contact plate 42 and the mounting plate frame 4. Liquid storage pipes 43 are fixed to the lower left and right sides of the contact plate 42.

[0044] like Figure 11 and Figure 12 As shown, the lower part of the contact plate 42 is provided with an inclined surface.

[0045] When the worker moves the SMC insulation plate to the left, the SMC insulation plate contacts and presses against the contact plate 42, causing the contact plate 42 and the liquid storage tube 43 to move upward. The second elastic component 41 is then compressed, and under the action of the second elastic component 41, the contact plate 42 can remain in close contact with the SMC insulation plate. When the cutting machine in the cutting module 12 cuts the SMC insulation plate and causes the SMC insulation plate and the contact plate 42 to vibrate, the elastic deformation characteristics of the second elastic component 41 and the viscosity of the liquid in the liquid storage tube 43 can effectively dampen the SMC insulation plate, thereby avoiding the vibration from affecting the cutting quality of the device or even causing safety hazards such as equipment damage. When the SMC insulation plate moves to the left and separates from the contact plate 42, the contact plate 42 and the liquid storage tube 43 will move downward and reset under their own weight and the elastic force of the second elastic component 41.

[0046] like Figure 13 and Figure 14 As shown, it also includes a cleaning mechanism, which is set on the mounting frame 14. The cleaning mechanism includes a guide pipe 5, a suction block 51 and a suction fan 52. The suction block 51 is fixed to the top front side of the mounting frame 14, and the suction fan 52 is fixed to the bottom rear side of the frame 1. The guide pipe 5 is fixed and connected between the suction fan 52 and the suction block 51.

[0047] When workers use cutting tools 18 and blades 110 to remove burrs and flash from the SMC insulation board, they can also start the suction fan 52. The suction fan 52 can clean and collect the cut burrs and flash through the suction block 51 and the guide pipe 5, thus preventing the burrs and flash from scattering everywhere with the wind and causing environmental pollution or even harming nearby workers. The suction fan 52 can be turned off when not needed.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
