Description

Technical Field

[0001] This invention relates to composite material manufacturing equipment, and particularly to a continuous fiber planar hot pressing composite machine. Background Technology

[0002] A continuous fiber planar hot press composite machine is a hot pressing molding device used to manufacture fiber-reinforced composite materials. This equipment utilizes high temperature and high pressure to combine reinforcing materials such as carbon fiber and glass fiber with a resin matrix, forming a composite material with excellent mechanical properties and lightweight characteristics. Historically, fiber composite materials have continuously evolved, encompassing fields such as aerospace, automotive, construction, and environmental protection.

[0003] In the prior art, the applicant filed a Chinese invention patent application with application number 201610266008.1 on April 25, 2016, which disclosed a continuous fiber planar hot pressing composite equipment. However, during the production, debugging, and use of the hot pressing composite equipment, the heating and cooling positions, i.e., the positions of the roller pressing composite machine, have the following problems.

[0004] First, in the existing technology, in order to ensure the smoothness of the composite material surface, a heat-resistant belt is used for transmission in the heating and cooling parts. That is, the belt needs to experience both high and low temperature states in one cycle, which affects the heating and cooling effect.

[0005] Secondly, during long-distance transmission, the heat-resistant belt may run off-center, which will greatly affect its performance.

[0006] Third, in the heating and cooling sections, the heating process usually requires multiple heating and cooling stages, meaning that the temperature rise and fall are a step-by-step process. Existing technologies involve temperature increases and decreases during the composite process, which means that the pipeline can only use insulated flexible hoses, leading to unnecessary maintenance difficulties.

[0007] Fourth, the flow of heating and cooling media within the metal heating jacket can cause the metal to warp, resulting in unevenness on the final composite material surface. Summary of the Invention

[0008] The purpose of this invention is to provide a continuous fiber planar hot pressing composite machine, which has the advantages of good heating and cooling effects, correction of deviation, step-by-step heating and cooling, and reduction of warping of metal heat transfer sleeve.

[0018] By adopting the above technical solution, the left support provides a fixed reference, and the right support drives one end of the correction roller to move horizontally, forming a fast tilt correction.

The infrared detection units are located on both sides of the C-shaped clamp in the height direction.

[0022] By adopting the above technical solution, the infrared detection structure can detect from two directions, reducing blind spots, while the signal detection is more stable and resistant to environmental interference.

[0023] Preferably, the lifting cooling roller assembly includes a support frame, which includes side plates respectively disposed on both sides. An upper cooling roller and a lower cooling roller are disposed between adjacent side plates. The upper and lower cooling rollers are on the same vertical plane. At least two upper and lower cooling rollers are provided in the feeding direction. An upper sliding cavity for lifting the upper cooling roller is provided on the side plate, and a lower sliding cavity for mounting the lower cooling roller is provided on the side plate.

[0024] By adopting the above technical solutions, independent lifting and cooling are achieved, improving the cooling effect while avoiding damage to materials, and adapting to different process requirements.

[0025] Preferably, the lifting cooling roller assembly includes symmetrically arranged lower cooling rollers and symmetrically arranged and independently lifting upper cooling rollers. The conveyor belt includes two sets, one set of which passes sequentially through the heating frame and the lifting cooling roller assembly, and the other set of which passes sequentially through the lifting cooling roller assembly and the cooling frame.

[0026] By adopting the above technical solution, two different conveyor belt transmission methods are supported.

[0027] In summary, the hot press laminating machine incorporates multi-segment temperature control in its frame structure to achieve precise temperature control. This allows the fiber material to undergo gradient heating and cooling processes, preventing deformation caused by sudden temperature changes. The lifting and cooling roller assembly serves as a transition zone, controlling both temperature and tension. Each hot and cold temperature zone has a lifting frame and a turbine screw jack, which can dynamically adjust the contact pressure between the heat transfer surface and the material. The dual upper and lower configuration of the metal heat transfer sleeve, combined with the separate design of the medium pipeline and the flexible hose, solves the problem of easy kinking and leakage in the pipeline during the lifting process of the heat transfer medium in existing equipment. It also solves the deformation of the medium when passing through the metal heat transfer pipe during the hot and cold processes, ensuring that the long-length metal heat transfer sleeve does not deform at high temperatures and correcting conveyor belt deviation in real time.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings.

[0048] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0049] Example:

[0050] like Figures 1 to 3 As shown, a continuous fiber planar hot pressing composite machine includes, in sequence, a heating frame 010, a lifting and cooling roller assembly, and a cooling frame 020. The heating frame 010 is located in the front section, the lifting and cooling roller assembly is located between the heating frame 010 and the cooling frame 020, and the cooling frame 020 is located in the rear section. The heating frame 010 includes a front heating section 011 and a rear heating section 012, and the cooling frame 020 includes a front cooling section 021 and a rear cooling section 022. Each of the front heating section 011, the rear heating section 012, the front cooling section 021, and the rear cooling section 022 includes a frame 300. A lifting frame 300 is installed within the frame 300, and a turbine screw jack 030 is installed on the frame 300 to drive the lifting frame 300 to move up and down and is connected by a universal joint. A metal heat transfer sleeve is installed inside the frame 300. A metal heat transfer sleeve is also installed below the lifting frame 300. A conveyor belt is installed between the heating frame 010, the lifting cooling roller group and the cooling frame 020. A medium pipeline 040 is installed on the top of the frame 300. The medium pipeline 040 includes an upper pipeline 041, a movable pipeline 042 and a lower pipeline 043. The upper pipeline 041 is connected to the top of the frame 300, the lower pipeline 043 is connected to the bottom of the frame 300, the movable pipeline 042 is connected to the lifting frame 300, the upper pipeline 041 and the lower pipeline 043 are connected, and the upper pipeline 041 and the movable pipeline 042 are connected by a flexible hose. The metal heat transfer sleeve is connected with an anti-bending structure, and a swing correction structure is installed inside the frame 300.

[0051] Meanwhile, the lifting and lowering cooling roller assembly includes symmetrically arranged lower cooling rollers and symmetrically arranged and independently lifting upper cooling rollers. There are two transmission methods for the conveyor belt. One is that the conveyor belt passes from the feeding heating clamp position through the cooling roller assembly to the outlet of the cooling rack 020, and is arranged symmetrically from top to bottom. The other is that the conveyor belt includes two sets. One set of the conveyor belt passes through the heating rack 010 and the lifting and lowering cooling roller assembly in sequence, and the other set of the conveyor belt passes through the lifting and lowering cooling roller assembly and the cooling rack 020. At the same time, each set of conveyor belts has two radially arranged ones in the height direction.

[0052] like Figures 4 to 8As shown, the lifting and cooling roller assembly of the laminating machine includes a support frame 200, which is part of the overall frame of the laminating machine. The overall structure of the support frame 200 includes side plates 210, top support rods 211, bottom support rods 212, and a base 213 respectively disposed on both sides. The side plates 210 are metal plates, the top support rods 211 and bottom support rods 212 are metal square tubes, and the base 213 is a metal L-shaped plate with reinforcing ribs. The base 213 is disposed at the bottom of the inward side of the side plates 210 and extends along the length of the side plates 210. The top support rods 211 are disposed on the inner side of the top of the side plates 210 and are disposed at both ends of the side plates 210 and between adjacent upper sliding cavities 220. The bottom support rods 212 are disposed at both ends of the side plates 210 and between adjacent lower sliding cavities 225.

[0053] like Figures 4 to 8 As shown, an upper cooling roller 231 and a lower cooling roller 232 are arranged between adjacent side plates 210. The upper cooling roller 231 and the lower cooling roller 232 are located on the same vertical plane. At least two upper cooling rollers 231 and two lower cooling rollers 232 are arranged in the feeding direction. In this invention, there are two upper cooling rollers 231 and two lower cooling rollers 232, and both are provided with cooling water channels to cool the surface of the roller body 233. In order to ensure that the upper cooling roller 231 and the lower cooling roller 232 can rotate, the two ends of the upper cooling roller 231 and the lower cooling roller 232 in the length direction are rotatably connected to bearing seats 240. The bearing seats 240 are provided with self-aligning roller bearings 242 connected to the outside of the roller shaft 238, so that the cooling rollers can rotate and be supported.

[0054] like Figures 5 to 7 To achieve the lifting and lowering of the upper cooling roller 231, the side plate 210 is provided with an upper sliding cavity 220 for the upper cooling roller 231 to lift and lower, and a lower sliding cavity 225 for the lower cooling roller 232 to be installed. The upper sliding cavity 220 and the lower sliding cavity 225 are rectangular, and the lower sliding cavity 225 is located directly below the upper sliding cavity 220. A lifting and sliding structure is provided between the bearing seat 240 of the upper cooling roller 231 and the side plate 210. The lifting and sliding structure specifically includes a sliding plate 251, a sliding track 252 and a slider 253. The bearing seat 240 is connected to the sliding plate 251. The sliding tracks 252 are arranged side by side on both sides of the upper sliding cavity 220 in the width direction. At least two sliders 253 are slidably connected on each sliding track 252. The sliders 253 are connected to the sliding plate 251.

[0055] like Figure 7As shown, a lifting drive device 250 is provided on the top of the upper sliding cavity 220. The lifting drive device 250 includes a servo linear motor, a pneumatic cylinder, or a hydraulic cylinder. In this embodiment, a hydraulic cylinder is used. In practice, a servo linear motor can be used to completely replace it, which has the advantages of higher stability and accuracy. The connection structure between the two includes a hinge seat 256. The execution end of the lifting drive device 250 is provided with a Y-type connector 254. The bearing seat 240 is provided with a fixed plane 255 that cooperates with the hinge seat 256. The Y-type connector 254 is rotatably connected to the hinge seat 256.

[0056] To facilitate the installation of the lower cooling roller 232, lower fixing structures are provided at both ends of the lower cooling roller 232 along its length.

[0057] To limit the downward movement of the upper cooling roller 231, the width of the sliding cavity 225 is smaller than the width of the upper sliding cavity 220 and a stepped surface 221 is formed. A limiting plate 222 is provided on the stepped surface 221. The limiting plate 222 is L-shaped and bolted to the inner side of the side plate 210. The limiting plate 222 is provided with a limiting structure to limit the maximum downward stroke of the upper cooling roller 231. The limiting structure includes a screw 223 and a nut 224. A through hole for the screw 223 to pass through is provided in the center of the limiting plate 222. The nut 224 is welded above the through hole and threadedly connected to the screw 223. The end of the screw 223 is located above the limiting plate 222 and abuts against the bottom of the bearing seat 240, thereby limiting the downward movement of the upper cooling roller 231.

[0058] like Figure 6 As shown, in order to fix the lower cooling roller 232, a fixing structure is provided between the bearing seat 240 of the lower cooling roller 232 and the side plate 210. The fixing structure includes a cover plate and a semi-circular groove 226 provided at the bottom of the sliding cavity 225. The semi-circular groove 226 cooperates with the circumferential side of the bearing seat 240 of the lower cooling roller 232. The cover plate is provided at the end of the bearing seat 240. The cover plate is connected to the side plate 210 by bolts.

[0059] like Figure 5 As shown, the bearing housing 240 is provided with a rotation drive device for driving the upper cooling roller 231 or the lower cooling roller 232 to rotate. The rotation drive device includes a motor reducer 243, an outer flange 244 is provided on the motor reducer 243, and an inner flange 241 connected to the outer flange 244 is provided on the bearing housing 240.

[0060] like Figures 5 to 8As shown, cooling water channels are provided inside the upper cooling roller 231 and the lower cooling roller 232. The cooling water channels are used to cool down the roller body 233. The cooling water channels include the roller body 233, the front mixing chamber 234, the rear mixing chamber 235, the spiral groove surface 236, the roller surface 237, and the roller shaft 238. The front mixing chamber 234 and the rear mixing chamber 235 are located at both ends of the length direction of the roller body 233, respectively. The spiral groove surface is set between the front mixing chamber 234 and the rear mixing chamber 235. The roller shaft is located at both ends of the length direction of the roller body 233. A water passage hole 239 is provided through the roller shaft. The water passage hole 239 communicates with the front mixing chamber 234 and the rear mixing chamber 235. The roller surface 237 is located outside the spiral groove surface 236 and is used for contact cooling with the composite sheet.

[0061] like Figure 4 As shown, in order to ensure that the composite sheet can be supported at the front and back, the two ends of the side plate 210 in the length direction are provided with support plates 214 for supporting materials. The support plates 214 are higher than the top of the lower cooling roller 232 and lower than the bottom of the upper cooling roller 231. The support plates 214 are located on the outer side of the side plate 210.

[0062] like Figures 9 to 13 As shown, the anti-bending structure of the heating module of the composite machine is set on each lifting frame 100. The lifting frame 100 is connected to the servo motor and the main frame, and plays the role of raising and lowering the metal heat transfer sleeve in the height direction. In this embodiment, the upper part of the lifting frame 100, that is, the lower part of the metal heat transfer sleeve, is the working surface. In actual use, the lifting frame 100 is mirrored in the height direction of the main frame.

[0063] like Figure 9 As shown, the lifting frame 100 includes symmetrical lifting rods 110 in the width direction. Multiple positioning and fixing rods 111 are connected between adjacent lifting rods 110. The positioning and fixing rods 111 are evenly distributed along the length direction of the lifting rods 110. A metal temperature transfer sleeve 120 is provided between adjacent positioning and fixing rods 111. The metal temperature transfer sleeve 120 extends along the length direction of the positioning and fixing rod 111, and the length of the metal temperature transfer sleeve 120 is shorter than that of the positioning and fixing rod 111. Sub-supports 130 are fixedly connected between adjacent positioning sliding rods. The sub-supports 130 are distributed along the length direction of the sliding rod. A sliding unit 140 is slidably connected in each sub-support 130. The sliding units 140 are distributed and connected in the length direction of the metal temperature transfer sleeve 120. The sliding units 140 slide along the length direction of the sliding rod.

[0064] like Figure 10As shown, a sub-bracket 130 is clamped between adjacent positioning and fixing rods 111. The longitudinal section of the positioning and fixing rod 111 is I-shaped. Positioning cavities 131 are formed on both sides of the positioning and fixing rod 111 in the width direction. The positioning cavities 131 are arranged through the positioning and fixing rod 111 in the length direction. The two sides of the sub-bracket 130 in the width direction are fixed in the positioning cavities 131.

[0065] like Figure 10 As shown, the positioning and fixing rod 111 has a structure including a top plate 112, a vertical plate 113, and a bottom plate 114. The vertical plate 113 connects the top plate 112 and the bottom plate 114 at the middle. The width of the top plate 112 is smaller than the width of the bottom plate 114. To improve the structural strength and stability between adjacent positioning and fixing rods 111, a transverse support column 115 is provided between adjacent vertical plates 113. The vertical plate 113 is provided with a first connecting hole 116 for connecting the transverse support column 115. After the bolt passes through the first connecting hole 116, it is connected to the transverse support column 115, which serves to fix the transverse support column 115 and the vertical plate 113.

[0075] Working principle:

[0076] The composite sheet enters the frame driven by the conveyor belt. A metal heat-conducting sleeve heats the sheet. When the metal heat-conducting sleeve 120 warps upwards or downwards, adjacent sliding units of the metal heat-conducting sleeve 120 move horizontally to both sides under the action of the sliding units. The rolling shaft 147 rotates within the positioning cavity 131. After the metal heat-conducting sleeve 120 cools, the rolling shaft 147 retracts inwards to ensure the flatness of the bottom surface of the metal heat-conducting sleeve. The composite sheet passes between the upper cooling roller 231 and the lower cooling roller 232. A rotation drive device located outside the support frame 200 drives the upper cooling roller 231 and the lower cooling roller 232 to rotate independently. Simultaneously, a lifting drive device 250 drives the upper cooling roller 231 to rise and fall independently in the height direction through a connecting structure, ensuring that each set of upper and lower cooling rollers 232, according to different cooling temperatures, has... Different thickness controls prevent cooling indentations during sheet cooling. During lifting, the upper cooling roller 231 and lower cooling roller 232 are cooled via external pipes connected by water passages 239 at both ends along their length. During use, the Teflon conveyor belt passes through the C-clamp 367. When the infrared detection unit 368 detects obstruction or lack thereof, the linear actuator motor 350 drives the telescopic part 353 to extend, causing the second spherical bearing seat 341 to move forward while the first spherical bearing seat 331 remains in the same position. This causes the correction roller 320 to tilt to one side, straightening the Teflon belt. Conversely, when the linear actuator motor 350 drives the telescopic part 353 to retract, the second spherical bearing seat 341 moves backward, causing the correction roller 320 to tilt to the other side, straightening the Teflon belt. This effectively corrects the Teflon belt's alignment.
