Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber product processing equipment, in particular to a carbon fiber tube winding device and a processing system. Background Art

[0002] Carbon-carbon composite barrels are suitable for high-temperature thermal fields, aviation, military, automobiles and other fields. Currently, carbon-carbon insulation barrels are mostly made by wrapping carbon fiber raw materials on a cylindrical mold to form a barrel.

[0003] During the processing, the carbon fiber needs to be sent to the oven for drying after the barrel is formed. Now, cylindrical molds with draft angles are mostly made, and they are removed from the small head of the mold after drying. Or use a jack to violently separate the mold and the workpiece from the side. However, the cylindrical mold with a draft angle can indeed be easily demolded when the draft angle is large enough, but more raw materials will be consumed when making the product, and there will be more processing losses, and violent demolding will easily damage the workpiece. When the integrated wooden or iron mold is baked at high temperature, the thermal expansion coefficient is too large, and it is often difficult to remove the carbon fiber cylinder from the cylindrical mold after baking and drying.

[0028] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] See also Figure 1 The carbon fiber drum winding device provided in this embodiment includes a main frame 100, a rotating mechanism 200, a drum assembly 300 and a pressing mechanism 400.

[0030] The main frame 100 has a mounting portion. The rotating mechanism 200 is disposed at the mounting portion, and the rotating mechanism 200 has a rotating end. The reel assembly 300 includes a winding roller and a heat shrink layer, the winding roller is disposed at the main frame 100, and the rotating shaft of the winding roller is transmission-connected with the rotating end, and the heat shrink layer is disposed on the surface of the winding roller. The pressing mechanism 400 includes a driving assembly and a pressing roller 410, the driving assembly is disposed at the main frame 100, and the driving assembly has a moving end, and the pressing roller 410 is transmission-connected with the moving end to approach or move away from the mounting portion.

[0031] The main frame 100 in this embodiment is a gantry structure with a stable structure and stable support. The rotating mechanism 200, the reel assembly 300 and the pressing mechanism 400 are all arranged on the main frame 100. When the carbon fiber raw material is rolled up, one end of the carbon fiber is fixed on the heat shrinkable layer, and then the rotating mechanism 200 is driven to drive the winding roller to rotate, so that the carbon fiber raw material is rolled up onto the winding roller to form a carbon fiber tube.

[0032] Furthermore, during the winding process, the pressing roller 410 is close to the winding roller to compress the carbon fiber raw material wound on the surface of the winding roller, so that the carbon fiber can be more compact after being wound into a roll and the wall thickness of the carbon fiber roll is more uniform.

[0033] After winding, wrap tape around the outside of the carbon fiber tube on the surface of the winding roller to tightly wrap and fix the carbon fiber tube, remove the winding roller from the main frame 100, and bake the winding roller and the carbon fiber tube together. The heat shrinkable layer shrinks after baking, so that a gap is generated between the winding roller and the carbon fiber tube, so that the carbon fiber tube can be separated from the winding roller through the gap when demolding, thereby achieving smooth demolding and avoiding demolding difficulties.

[0034] In this embodiment, the rotating mechanism 200 includes a rotating motor and a disc 210. The output shaft of the rotating motor is the rotating end. A transmission shaft is provided at the center of the disc 210, and the transmission shaft is connected to the rotating end. The disc 210 is provided on one side of the winding roller and is connected to the winding roller by transmission, and the transmission shaft is coaxial with the rotating shaft of the winding roller.

[0035] After the rotating end of the rotating motor is connected to the disc 210, it can drive the turntable to rotate along with the rotating end, thereby driving the winding roller to rotate, so that the winding roller can wind the carbon fiber raw material onto the surface of the winding roller.

[0036] In this embodiment, there are two disks 210. The two disks 210 are respectively disposed at two ends of the winding roller, and the rotating shafts of the two disks 210 are rotatably disposed on the main frame 100.

[0037] The two discs 210 can be connected to the winding roller at both ends of the winding roller, forming a rotating shaft on both sides of the winding roller. In this embodiment, two opposite shaft seats are provided on the main frame 100, and the rotating shafts of the two discs 210 are respectively placed in the two shaft seats so that the winding roller can rotate to roll the carbon fiber raw material into a roll.

[0038] In this embodiment, a plurality of bolts 220 are disposed on the disk 210 along the circumferential direction. The disk 210 and the winding roller are connected by the plurality of bolts 220.

[0039] Specifically, a plurality of screw holes are provided at both ends of the winding roller in this embodiment, and a connecting hole is provided on the disc 210. The bolts 220 are passed into the connecting holes and then screwed into the screw holes, thereby realizing the connection between the disc 210 and the winding roller.

[0040] The bolt 220 connection method is convenient for loading and unloading. After the carbon fiber tube is wound up, the winding roller and the carbon fiber tube can be easily removed from the disc 210 for baking.

[0041] In this embodiment, a fixing piece is provided on the heat shrinkable layer, and the fixing piece is used to connect the ends of the soft felt.

[0042] The fixing piece is used to connect the end of the soft felt (i.e., carbon fiber raw material). After connection, the winding roller is driven by the rotary motor and the disc 210 to rotate so that the soft felt follows the winding roller to rotate, so that the soft felt is wound around the surface of the winding roller to form a carbon fiber tube.

[0043] In this embodiment, the heat shrinkable layer includes a tarpaulin tape layer, which is evenly wound on the surface of the winding roller.

[0044] The tarpaulin tape is attached to the surface of the winding roller to form a heat shrink layer. During baking, the tarpaulin tape shrinks due to the heat, thereby forming a gap between the carbon fiber tube and the winding roller so that the carbon fiber tube and the winding roller can be separated.

[0045] In this embodiment, the fixing member is a double-sided adhesive tape. The double-sided adhesive tape is arranged on the surface of the heat shrinkable layer along the axial direction of the winding roller. Both sides of the double-sided adhesive tape have adhesive, which is very convenient to stick to the surface of the oilcloth tape, and the other side can be pasted to the end of the felt, which is very convenient to use.

[0046] Furthermore, in this embodiment, the double-sided adhesive tape is arranged in a straight line along the circumference of the winding roller on the heat shrinkable layer formed by the oil cloth tape, which can make the ends of the felt flush, thereby further ensuring the uniform thickness of the carbon fiber tube.

[0047] In this embodiment, the driving assembly includes a driving member and a mounting frame 420. A transmission hole 110 is provided at the top of the main frame 100. The driving member is provided at the top of the main frame 100, and the output shaft of the driving member is inserted into the transmission hole 110, and the end of the output shaft of the driving member is the moving end. The mounting frame 420 is provided between the driving member and the winding roller and connected to the moving end, and the pressing roller 410 is provided on the mounting frame 420.

[0048] Specifically, the driving member is at the top of the main frame 100, and the mounting frame 420 is located between the driving member and the winding roller. When the dough pressing action is performed, the driving member pushes the mounting frame 420 toward the winding roller through the output shaft, thereby driving the dough pressing roller 410 to press the carbon fiber tube wrapped around the outer wall of the winding roller.

[0049] When the winding roller drives the carbon fiber tube to rotate, the pressing roller 410 rotates along with the carbon fiber tube, pressing the carbon fiber tube to ensure that the tube wall thickness of the carbon fiber tube is uniform while preventing the carbon fiber raw material from rolling up due to friction.

[0050] In this embodiment, the thrust of the driving member is not less than 2 kg.

[0051] Specifically, in this embodiment, the thrust of the driving member is 2 kg, that is, the pressure applied by the clamping roller on the carbon fiber tube is 2 kg, which can achieve the compaction and compaction of the carbon fiber raw material and avoid uneven wall thickness of the carbon fiber tube formed after winding.

[0052] It should be noted that, during the winding process, the present embodiment uses an automatic glue spraying machine to continuously and evenly spray glue onto the surface of the carbon fiber tube, so that the layers of raw materials of the carbon fiber tube are bonded to each other.

[0053] The processing system provided in this embodiment includes a carbon fiber tube winding device.

[0054] When the carbon fiber raw material is rolled up, one end of the carbon fiber is fixed on the heat shrink layer, and then the rotating mechanism 200 is driven to drive the winding roller to rotate, so that the carbon fiber raw material is rolled onto the winding roller to form a carbon fiber tube. In addition, during the winding process, the pressure roller 410 is close to the winding roller to press the carbon fiber raw material wrapped on the surface of the winding roller, so that the carbon fiber can be more compact after being rolled into a tube, and the tube wall thickness of the carbon fiber tube is more uniform. After winding, the tape is wrapped around the carbon fiber tube on the surface of the winding roller to wrap the carbon fiber tube tightly and fix it, the winding roller is removed from the main frame 100, and the winding roller and the carbon fiber tube are baked together. The heat shrink layer shrinks after baking, so that a gap is generated between the winding roller and the carbon fiber tube, so that the carbon fiber tube can be separated from the winding roller through the gap when demoulding, thereby achieving smooth demoulding and avoiding demoulding difficulties.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
