Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to an anti-warping mechanism for fiberglass sheet molding. Background Technology

[0002] Fiberglass reinforced plastic (FRP) sheets, with their excellent properties such as light weight, high strength, corrosion resistance, and insulation, are widely used in many fields, including construction, automotive, shipbuilding, and chemical industries. For example, in construction, they are used for roofing panels and wall panels; in the automotive industry, for body parts and interior components; and in shipbuilding, for hull structures and decks. FRP sheets are typically composed of glass fibers and their products with a resin matrix. During the curing process, due to differences in the density and fineness of the glass fibers in different material layers, the resin impregnation ratio varies in each layer. This results in uneven resin curing shrinkage, leading to warping.

[0003] A search revealed Chinese Patent Publication No. CN217574038U, which discloses a warping correction and shaping device for fiberglass products. The device includes a base frame, a worktable mounted on top of the base frame, and several evenly distributed sliding grooves symmetrically arranged on both sides of the worktable. Sliding blocks are slidably matched to the sliding grooves, and a fixture is connected to the top of each sliding block. The fixture has several heat-conducting holes, and an air passage connecting all the heat-conducting holes is provided inside the fixture. A connector is threaded to the input end of the air passage. Several telescopic cylinders are mounted on the worktable, with their output ends connected to the side of the fixture. A mounting plate is mounted on the side of the fixture, and a pneumatic clamp is mounted on the mounting plate. The output end of the pneumatic clamp is located on the upper side of the fixture. Several fans are mounted on the worktable, and a control box is mounted on the base frame.

[0004] The aforementioned patent specification mentions that "when using a fiberglass product warpage correction and shaping device, the dimensions of the fiberglass to be corrected are visually estimated, and then the telescopic cylinder 9 at the corresponding position is controlled to move the fixture 5 at the slide groove 3 position, thereby ensuring that the fiberglass can be placed freely on the fixture 5. Then, the clamp 11 is activated for positioning, and hot air is injected into the air passage 7 through the connector 8. The gas is discharged from the heat conduction hole 6 to soften the fiberglass. Under the effect of the clamp 11, the warped and softened fiberglass will become flat after cooling, achieving the purpose of correcting warpage. The cooling method can be natural cooling or the cooling effect can be enhanced by activating the fan 12 to generate wind." The above content can achieve the purpose of correcting fiberglass warpage. However, during the fiberglass sheet forming process, it will be transported and formed on the conveyor belt for a long time. At this time, the edge of the film will warp. Therefore, a mechanism to prevent warpage is needed while the fiberglass sheet is being formed and transported. To solve this problem, a fiberglass sheet forming anti-warpage mechanism is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a fiberglass sheet forming anti-warping mechanism, which aims to improve the problem of warping at the edges of some existing devices during film production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fiberglass sheet forming anti-warping mechanism includes an edge bracket, a bracket one threadedly connected to the top of the edge bracket, a bracket two rotatably connected to the top of the bracket one, a pressing mechanism inside the bracket two, and a limited displacement mechanism on both sides of the outside of the bracket one. The clamping mechanism includes an upper rod, which is slidably connected to the outside of the second bracket. An upper wheel is rotatably connected to the outside of the upper rod. A counterweight is snapped onto the outside of the upper rod. A disassembly assembly is slidably connected to the outside of the upper rod. A lower rod is slidably connected to the inside of the first bracket. A lower wheel is rotatably connected to the outside of the lower rod. A support rod is slidably connected to the outside of the upper rod. A slot is fixedly connected to the other end of the support rod. An adjustment assembly is threaded onto the outside of the first bracket. A hinge assembly is rotatably connected to the inside of the second bracket. Through the above technical solution: the first bracket at the top of the edge bracket is stably fixed by a threaded connection, providing reliable support for the overall mechanism; the second bracket at the top of the first bracket can adjust its angle by rotating the hinge assembly; in the pressing mechanism, the upper rod can slide inside the second bracket to adjust its position; the upper wheel outside the upper rod can move and rotate with the plate; the counterweight block snapped onto the outside of the upper rod can increase the pressure of the upper wheel on the plate, enhancing the anti-warping effect; the disassembly assembly outside the upper rod can slide to achieve quick disassembly and maintenance of the upper wheel and other components; the lower rod inside the first bracket can slide and adjust; and the lower wheel outside the lower rod can... Synchronous rotation, in conjunction with the operation of the upper wheel, allows the external support rod of the upper rod to slide, while its other end can engage with and support the lower rod, stabilizing the relative positions of the upper and lower rods. The external adjustment component of bracket one, connected by threads, can precisely adjust the positions of the upper and lower rods, thereby adjusting the pressing area. Ultimately, the upper and lower rods, through the upper and lower wheels, form a bidirectional pressing force on the fiberglass sheet, which, combined with the force-increasing effect of the counterweight, enhances the anti-warping effect. The disassembly of the components facilitates maintenance and replacement of parts. The hinge component, in conjunction with the rotation of bracket two, enables flexible operation of the mechanism, meeting the sheet forming requirements under different working conditions.

[0007] As a further description of the above technical solution: The limiting mechanism includes a connecting plate, the external thread of which is connected to the outside of the bracket one, a support frame is fixedly connected to the outside of the connecting plate, a connecting rod is fixedly connected to the top of the support frame, a baffle is fixedly connected to the outside of the connecting rod, a roller is rotatably connected to the outside of the support frame, a connecting clamp is rotatably connected to the outside of the connecting rod, and a connecting nut is threaded onto the outside of the connecting clamp. Through the above technical solution: when the limiting mechanism is running, the connecting plate connects the limiting mechanism to the support frame. On the support frame, the roller contacts the side of the fiberglass sheet. When the sheet moves, the roller rotates around its own axis and limits the sheet through rolling friction. The connecting tube connected to the outside of the connecting rod rotates to cover the roller. By turning the connecting nut, the position of the connecting tube on the connecting rod can be adjusted, thereby adjusting the position of the roller. The baffle fixed outside the connecting rod limits the range of movement of the roller, ensuring that the roller is always in the appropriate position to limit the sheet.

[0008] As a further description of the above technical solution: The hinge assembly includes a shaft, the outside of which is rotatably connected to the inside of the bracket two, and the inside of which is threadedly connected to a threaded shaft; With the above technical solution: when the hinge assembly is running, the threaded shaft is loosened, and the shaft can rotate within the bracket two. After adjusting to a suitable angle, the threaded shaft is tightened to fix the angle of the bracket two.

[0009] As a further description of the above technical solution: The shaft is externally rotatably connected to the inside of bracket one, and the threaded shaft is externally supported inside of bracket two. The above technical solution involves: loosening the threaded shaft, allowing the shaft center to rotate within bracket one and bracket two, adjusting the angle of bracket two; and tightening the threaded shaft, which supports bracket two and fixes the current angle.

[0010] As a further description of the above technical solution: The disassembly assembly includes a fixing clamp tube, the inside of which is slidably connected to the outside of the upper rod, and the outside of which is threaded with a tightening nut, and the outside of which is supported by the tightening nut on the outside of the upper rod. Through the above technical solution: when disassembling the components, when installing the upper wheel and counterweight, the fixing tube is slidably sleeved on the corresponding position of the upper rod so that it fits against the component to be fixed. Then, the nut is tightened, and the fixing tube is fixed by the supporting effect of the tightening nut and the upper rod, thereby firmly fixing the component to the upper rod.

[0011] As a further description of the above technical solution: The adjustment assembly includes a second screw, the external thread of which is connected to the interior of the first bracket, and the external thread of the second bracket is connected to the first screw; The above technical solution allows for the following: by rotating screw one, the position of the upper rod can be adjusted; the lower rod inside bracket one can slide; the lower rod drives the lower wheel to contact the lower surface of the plate; rotating screw two can adjust the position of the lower rod; and the upper and lower wheels cooperate to press the plate together.

[0012] As a further description of the above technical solution: The roller is externally supported on the top of the baffle, the connecting tube is externally supported on the outside of the roller, and the connecting nut is externally supported on the outside of the connecting rod. The above technical solution involves fitting the roller onto the connecting tube, fixing the position of the connecting tube on the connecting rod by tightening the connecting nut, and supporting the top of the roller on the baffle to achieve the positioning of the roller.

[0013] As a further description of the above technical solution: The external support of the first screw is on the outside of the upper rod, and the external support of the second screw is on the outside of the lower rod; The above technical solution allows for the adjustment of the support position of the upper rod by rotating screw one, and the adjustment of the support position of the lower rod by rotating screw two, thus enabling the control of the positions of the two rods.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when the upper and lower wheels are respectively pressed against the upper and lower surfaces of the fiberglass sheet, the support rod slidably connected to the upper rod has a groove at the bottom that forms a tight support fit with the lower rod, providing precise limiting support for the upper rod sliding inside the bracket. This effectively prevents the upper and lower rods from shifting or shaking during the pressing process, ensuring that the pressing force of the upper and lower wheels is evenly applied to the upper and lower surfaces of the fiberglass sheet. Combined with the increased pressure from the counterweight block externally attached to the upper rod, the warping phenomenon caused by uneven force on the edge of the fiberglass sheet can be further suppressed, significantly improving the quality and stability of the fiberglass sheet molding production. This achieves the effect of assisting in stabilizing the relative position of the upper and lower rods, ensuring the stability of the pressing operation, and reducing the problem of warping at the edge of the fiberglass sheet during the production process.

[0015] 2. In this utility model, with the threaded connection between the connecting plate and the bracket and the fixed connection between the connecting plate and the support frame, the movement limiting mechanism is stably connected to the bracket, providing stable support for the operation of the roller. The baffle fixed on the connecting rod, together with the connecting clamp and the connecting nut, enables the roller to be stably and accurately in the appropriate limiting position. When the sheet moves, the lateral movement is limited by rolling friction, so as to solve the problem that the fiberglass sheet is prone to lateral displacement during the molding process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a fiberglass sheet forming anti-warping mechanism, including an edge support 1, which is a support structure for the edge of a conveyor belt. The top of the edge support 1 is threadedly connected to a support 2, which is a key component connecting the pressing mechanism 5 and the displacement limiting mechanism 4. The support 2 is fixed to the edge support 1 by means of a threaded connection structure with a waist hole. The top of the support 2 is rotatably connected to a support 3. The support 3 adjusts the angle of the pressing mechanism 5 through its rotatable connection with the support 2, thereby better pressing the fiberglass sheet. The pressing mechanism 5 is provided inside the support 3, and the displacement limiting mechanism 4 is provided on both sides of the support 2. Specifically, the fiberglass sheet forming anti-warping mechanism includes an edge bracket 1, which serves as a support structure for the edge of the conveyor belt. The top of the bracket is connected to a first bracket 2 by a thread. The first bracket 2 is fixed to the edge bracket 1 by a threaded connection structure through a waist hole. It is a key component connecting the pressing mechanism 5 and the displacement limiting mechanism 4. The top of the first bracket 2 is rotatably connected to a second bracket 3. The angle of the pressing mechanism 5 can be adjusted by the rotatable connection between the second bracket 3 and the first bracket 2. The pressing mechanism 5 is installed inside the second bracket 3, and the displacement limiting mechanism 4 is installed on both sides of the outside of the first bracket 2.

[0025] The pressing mechanism 5 includes an upper rod 51, which supports an upper wheel 52 and a counterweight 57. The upper rod 51 is slidably connected to the inside of the bracket 2 3. The upper wheel 52 is rotatably connected to the outside of the upper rod 51. The upper wheel 52 contacts the upper surface of the fiberglass sheet and applies pressure to the sheet through rolling friction. The counterweight 57 is snapped onto the outside of the upper rod 51. The counterweight 57 increases the pressure of the upper rod 51 and upper wheel 52 on the sheet, further enhancing the anti-warping effect. A disassembly assembly 58 is slidably connected to the outside of the upper rod 51. A disassembly assembly 58 is also installed on the outside of the lower rod 53. The lower rod 53 is slidably connected to the inside of the bracket 2 and supports a lower wheel 54. The lower rod 53 is rotatably connected to the outside of the lower rod 53. Wheel 54 contacts the lower surface of the fiberglass sheet and cooperates with upper wheel 52 to press the sheet from both above and below, enhancing the anti-warping effect. Support rod 55 is slidably connected to the outside of upper rod 51. Support rod 55 is used to connect upper rod 51 and slot 56. The other end of support rod 55 is fixedly connected to slot 56. Slot 56 is used to support lower rod 53 and help stabilize the relative position of upper rod 51 and lower rod 53. Adjustment component 59 is threadedly connected to the outside of bracket 1 2. Hinge component 510 is rotatably connected to the inside of bracket 2 3. Roller 45 is externally supported on top of baffle 44. Connecting tube 46 is externally supported on the outside of roller 45. Connecting nut 47 is externally supported on the outside of connecting rod 43. Specifically, in the clamping mechanism 5, the core function of the upper rod 51 is to support the upper wheel 52 and the counterweight 57. It is externally slidably connected inside the bracket 2 3 and its position can be adjusted according to the thickness of the plate. The upper wheel 52 is rotatably connected to the outside of the upper rod 51 and contacts the upper surface of the fiberglass plate during operation. Pressure is applied through rolling friction. The counterweight 57 is snapped onto the outside of the upper rod 51 and can be flexibly added or removed to adapt to the clamping requirements of different plates. The lower rod 53 is slidably connected inside the bracket 1 2 and externally rotatably connected to the lower wheel 54, which contacts the lower surface of the plate and forms a clamping structure with the upper wheel 52. The support rod 55 is slidably connected to the outside of the upper rod 51 and is supported on the lower rod 53 through the end-fixed slot 56 to ensure the stability of the positions of the upper and lower rods 53. The adjusting component 59 and the hinge component 510 are used to adjust the position of the components and the angle of the bracket, respectively, to ensure the overall adaptability of the clamping mechanism 5.

[0026] Reference Figure 2 , Figure 4 and Figure 5 The disassembly assembly 58 includes a fixing tube 581, which is internally slidably connected to the outside of the upper rod 51. The fixing tube 581 is used to cooperate with the tightening nut 582 to fix the position of the upper wheel 52 and the counterweight 57. The tightening nut 582 is threadedly connected to the outside of the fixing tube 581. The tightening nut 582 is externally supported on the outside of the upper rod 51. The fixing tube 581 is firmly locked to the upper rod 51 by the thread force. Specifically, the core function of the disassembly component 58 is to enable the quick loading and unloading of the upper wheel 52 and the counterweight 57 to adapt to the production needs of fiberglass sheets of different specifications. During installation, first, place the upper wheel 52 and the counterweight 57 on the designated position of the upper rod 51, then slide the fixing tube 581 to the outside of the upper rod 51, and finally tighten the external tightening nut 582. The fixing tube 581 is fixed by the supporting force of the nut and the upper rod 51. During disassembly, simply loosen the tightening nut 582 and slide the fixing tube 581 to easily disassemble the upper wheel 52 or the counterweight 57. The operation is convenient and efficient.

[0027] The adjusting assembly 59 includes a second screw 592, the external thread of which is connected to the inside of the first bracket 2. The second screw 592 is used to adjust and fix the position of the lower rod 53. The second bracket 3 is externally threaded with a first screw 591, which is used to adjust and fix the position of the upper rod 51. The external support of the first screw 591 is on the outside of the upper rod 51, and the external support of the second screw 592 is on the outside of the lower rod 53. Specifically, the adjustment component 59 consists of screw 1 591 and screw 2 592, which correspond to the position adjustment of the upper rod 51 and the lower rod 53, respectively. When the height of the upper rod 51 needs to be adjusted, screw 1 591 on the outside of bracket 2 3 is rotated. Screw 1 591 moves inside bracket 2 3 through threaded transmission, and its end moves away from the upper rod 51, allowing it to slide, thereby adjusting the position of the upper rod 51. When adjusting the lower rod 53, screw 2 592 on the outside of bracket 2 is rotated, and its end moves away from the lower rod 53, allowing it to slide, thereby adjusting the position of the upper rod 51. Ultimately, the distance between the upper and lower rods 53 is precisely matched with the thickness of the plate, ensuring the pressing effect.

[0028] The hinge assembly 510 includes a shaft 5101, which is rotatably connected to the inside of the second bracket 3. The inside of the shaft 5101 is threadedly connected to a threaded shaft 5102, which adjusts and fixes the rotation angle between the first bracket 2 and the second bracket 3. The shaft 5101 is rotatably connected to the inside of the first bracket 2 and simultaneously connects the first bracket 2 and the second bracket 3, providing a fulcrum for their relative rotation. The threaded shaft 5102 is externally supported inside the second bracket 3, fixing the angle of the second bracket 3 through the supporting force. Specifically, the hinge assembly 510 is the core structure for adjusting the angle of bracket 2 3. It is rotatably connected to bracket 1 2 and bracket 2 3 through the shaft 5101, forming the basis for their relative rotation. When the angle of bracket 2 3 needs to be adjusted to adapt to the tilting requirements of the plate, the threaded shaft 5102 inside the shaft 5101 is loosened first. At this time, bracket 2 3 can rotate freely around the shaft 5101. After adjusting to the appropriate angle, the threaded shaft 5102 is tightened in the opposite direction so that its end is supported inside bracket 2 3. The locking force of the thread is used to fix the position of bracket 2 3, ensuring the stability of the angle of the pressing mechanism 5.

[0029] Reference Figure 1 , Figure 3 and Figure 6The limiting mechanism 4 includes a connecting plate 41, which connects the limiting mechanism 4 to the bracket 2, serving to fix and support the components of the limiting mechanism 4. The connecting plate 41 is externally threaded onto the outside of the bracket 2. A support frame 42 is fixedly connected to the outside of the connecting plate 41, supporting the connecting rod 43 and the roller 45, providing support for the limiting of the fiberglass sheet and ensuring that the sheet does not shift laterally during the molding process. A connecting rod 43 is fixedly connected to the top of the support frame 42, connecting the support frame 42 and the baffle 44. A baffle 44 is fixedly connected to the outside of the connecting rod 43, limiting the movement range of the roller 45 and ensuring that the roller 45 always limits the fiberglass sheet in the appropriate position. 2 is externally rotatably connected to a roller 45, which contacts the side of the fiberglass sheet and limits the sheet by rolling friction to prevent lateral movement during the forming process and reduce damage to the sheet surface. The connecting rod 43 is externally rotatably connected to a connecting tube 46, which is used to install the roller 45 on the connecting rod 43. The connecting tube 46 is externally threaded with a connecting nut 47, which cooperates with the connecting tube 46 to fix and adjust the position of the roller 45, ensuring that the roller 45 can limit the fiberglass sheet in the appropriate position. The roller 45 is externally supported on the top of the baffle 44, the connecting tube 46 is externally supported on the outside of the roller 45, and the connecting nut 47 is externally supported on the outside of the connecting rod 43. Specifically, the core function of the displacement limiting mechanism 4 is to prevent lateral displacement during the molding process of the fiberglass sheet. It is fixed to the bracket 2 by a threaded connection of the connecting plate 41. The support frame 42 serves as the core support component, with the connecting rod 43 fixed at the top and the external rotating connecting roller 45 providing a stable foundation for the limiting operation. The roller 45 contacts the side of the sheet, reducing damage to the sheet surface through rolling friction and limiting the lateral movement of the sheet. The baffle 44 is fixed to the outside of the connecting rod 43 to prevent the roller 45 from shifting position during operation. The connecting clamp tube 46 is sleeved on the outside of the connecting rod 43 to support the roller 45. The connecting nut 47 with external thread can adjust the position of the roller 45 by loosening or tightening to ensure that it can adapt to sheets of different widths.

[0030] Working principle: Edge bracket 1 serves as the support structure for the edge of the conveyor belt. Its top is fixedly connected to bracket 2 via a threaded connection structure with a waist hole. Bracket 2 simultaneously connects bracket 3, the pressing mechanism 5, and the limiting mechanism 4. The bottom of bracket 3 is rotatably connected to bracket 2 via a hinge assembly 510. When the angle of bracket 3 needs to be adjusted to fit the sheet metal, the threaded shaft 5102 inside the shaft 5101 is loosened. After adjusting to the appropriate angle, the threaded shaft 5102 is tightened, so that its external support is inside bracket 3, thus fixing the angle of bracket 3. The upper rod 51 is slidably connected inside bracket 3 and rotatably connected to the upper wheel 52 externally. During operation, the upper wheel 52 contacts the upper surface of the fiberglass sheet, applying pressure through rolling friction. The counterweight 57, which is snapped into place, can increase the pressure as needed. Meanwhile, the lower rod 53, which is slidably connected inside the bracket 2, and the lower wheel 54, which is rotatably connected externally, contact the lower surface of the plate and cooperate with the upper wheel 52 to form a clamping structure that effectively prevents the plate from warping. The screw 591, which is threaded externally connected to the bracket 3, is supported outside the upper rod 51. Rotating the screw 591 can adjust and fix the position of the upper rod 51. The screw 592, which is threaded externally connected to the bracket 2, is supported outside the lower rod 53. Similarly, it can adjust and fix the position of the lower rod 53. The support rod 55, which is slidably connected to the upper rod 51, is supported on the lower rod 53 through the end-fixed slot 56, further stabilizing the relative position of the upper rod 51 and the lower rod 53.

[0031] When disassembling component 58, when installing the upper wheel 52 and counterweight 57, first place the component on the designated position of the upper rod 51, then slide the fixing tube 581 to the outside of the upper rod 51, and tighten the external tightening nut 582. Use the supporting force of the nut and the upper rod 51 to fix the component. When disassembling, loosen the tightening nut 582, remove the fixing tube 581, and the upper wheel 52 and counterweight 57 can be easily removed.

[0032] The connecting plate 41 is threaded to the outside of the bracket 2, achieving a stable connection between the limiting mechanism 4 and the bracket 2. The support frame 42, which is fixedly connected to the outside of the connecting plate 41, serves as the main support component. The top of the connecting rod 43 is fixedly connected to the connecting rod 45, and the roller 45 is rotatably connected to the outside. During operation, the roller 45 contacts the side of the fiberglass sheet. When the sheet moves, the roller 45 is limited by rolling friction. The other end of the connecting rod 43 is fixedly connected to the baffle 44, which is used to limit the movement range of the roller 45. The roller 45 is sleeved on the connecting clamp tube 46. The connecting clamp tube 46 is rotatably connected to the outside of the connecting rod 43 and is fixed and adjusted by the connecting nut 47 with external thread to ensure that the roller 45 is in a suitable limiting position. At the same time, the top of the roller 45 is supported by the baffle 44, the connecting clamp tube 46 supports the roller 45, and the connecting nut 47 supports the connecting rod 43. All components work together to limit the lateral movement of the sheet.
