[0002] Carbon fiber is an inorganic polymer fiber with a high carbon content. The raw materials for producing carbon fiber include polyacrylonitrile, asphalt, and viscose fiber. It is made through humidification, pre-oxidation, carbonization, and graphitization processes. It not only has the inherent intrinsic properties of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fiber.

[0003] In the production process of carbon fiber tow, the carbon fiber raw yarn passes through the withdrawal rack and enters the oxidation furnace through the shutter of the oxidation furnace, and the pre-oxidation process of the fiber is completed in the oxidation furnace.

[0004] The existing shutters are composed of two smooth stainless steel blades fixed at the inlet and outlet of each layer of the oxidation furnace. The two ends of the stainless steel blades are fixed by a number of nuts. When adjusting them, most of them are manually disassembled by turning the bolts, and then the blades are adjusted and then the bolts are installed again. However, this adjustment method is cumbersome, time-consuming, and not very practical. In addition, most of the shutters are fixed to the carbon fiber oxidation furnace by multiple bolts. However, when the shutters are damaged, they need to be manually disassembled by turning the multiple bolts, which is cumbersome and reduces the maintenance efficiency. Utility Model Content

[0010] Preferably, a guide rod is fixed on the top of the mounting plate, and the sliding block slides along the guide rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, a rotating screw drives a sliding block outside the sliding block to slide down, and at the same time, a pawl block installed on the top of the sliding block through a connecting rod immediately slides down and disengages from the ratchet groove of the ratchet wheel. The manually rotating rocker drives the rotating rod to rotate, and the gear outside the sliding block also rotates immediately and meshes with multiple gears, so that multiple louver blades can synchronously adjust the wire feed contact height for the carbon fiber to enter the carbon fiber oxidation furnace, so that quick adjustment is achieved and the usability of the adjustment is improved.

[0027] See also Figures 1 to 4 The utility model provides a technical solution: a shutter device of a carbon fiber oxidation furnace, comprising a carbon fiber oxidation furnace body 1, a fixed plate 2 is fixed on the surface of the carbon fiber oxidation furnace body 1, a base 3 is fixed on the end side of the fixed plate 2, a detachable clamping block 4 is provided on the end side of the base 3, a shutter frame 5 is fixed on the end side of the clamping block 4, a rotatable rotating rod 6 is provided in the middle of the shutter frame 5, and a shutter blade 7 is fixed in the middle of the rotating rod 6.

[0028] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing rod 41 is fixed inside the base 3, a clamping rod 42 is rotatably sleeved outside the fixing rod 41, a screw groove 43 is provided outside the clamping rod 42, and a nut 44 is threadedly sleeved on the outside of the screw groove 43.

[0029] It should be noted that both ends of the clamping block 4 are provided with recesses for facilitating the insertion of the clamping rod 42. The clamping rod 42 can rotate around the fixing rod 41 to be inserted into the clamping block 4. The rotating nut 44 presses the clamping block 4 so that the shutter frame 5 and the carbon fiber oxidation furnace body 1 are firmly installed.

[0030] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the nut 44 is fitted with the clamping block 4 .

[0031] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a gear 61 is fixedly sleeved on the outer end of the rotating rod 6, a ratchet 63 is fixedly sleeved on the outer end of the rotating rod 6, a rocker 62 is fixed on the end of the rotating rod 6, and the rotating rod 6 is provided with a plurality of gears 61, which are meshed with each other.

[0032] It should be noted that a plurality of rotating rods 6 are provided in the shutter frame 5, and gears 61 are installed on the end sides of the plurality of rotating rods 6. The plurality of gears 61 are meshed with each other. Therefore, when the rotating rod 6 drives a gear 61 to rotate, the plurality of gears 61 are meshed and rotated, thereby driving a plurality of shutter blades 7 installed through the rotating rod 6 to rotate, thereby adjusting the height of the shutter blades 7.

[0033] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting plate 64 is fixed to the end side of the shutter frame 5, a screw rod 65 is rotatably connected in the middle of the mounting plate 64, a control rod 66 is fixed to the bottom of the screw rod 65, a slider 67 is sleeved on the external thread of the screw rod 65, a connecting rod 69 is fixed to the top of the slider 67, a pawl block 610 is fixed to the top of the connecting rod 69, and the pawl block 610 is meshed and connected with the ratchet wheel 63.

[0034] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a guide rod 68 is fixed on the top of the mounting plate 64 , and the slider 67 slides along the guide rod 68 .

[0035] The use method and advantages of the utility model: When the shutter device of the carbon fiber oxidation furnace is working, the working process is as follows:

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the shutter device, firstly, the shutter frame 5 and the block 4 are attached to the base 3, then the clamping rod 42 is turned over and rotated around the fixing rod 41, so that the clamping rod 42 is placed in the notch of the block 4, then the nut 44 is rotated to slide along the screw groove 43 on the outside of the clamping card until the nut 44 slides down and fits to the surface of the block 4 and then fixes it, so that the shutter frame 5 is installed between the carbon fiber oxidation furnace body 1 for easy use. When it is damaged and disassembled, the nut 44 is manually rotated to slide up along the screw groove 43 and then disengage from the block 4, then the clamping rod 42 is turned over and rotated around the fixing rod 41 to disengage from the block 4 and then contact the limit, so that it can be quickly disassembled for maintenance;

[0037] When adjusting the louver blades 7, the control rod 66 is manually rotated to drive the screw rod 65 to rotate. When the screw rod 65 rotates, the slider 67 with its external thread sleeve immediately slides horizontally along the guide rod 68, and at the same time, the pawl block 610 installed on the top of the slider 67 through the connecting rod 69 immediately slides down and disengages from the ratchet groove of the ratchet wheel 63. Then, the rocker 62 is manually rotated to drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, the gear 61 outside the rotating rod immediately rotates and meshes with other gears 61, so that multiple gears 61 mesh with each other and then drive multiple louver blades 7 to rotate synchronously, so that multiple louver blades 7 can synchronously adjust the wire contact height for the carbon fiber to enter the carbon fiber oxidation furnace, so that the adjustment is fast and the usability of the adjustment is improved;

[0038] After adjusting to the appropriate height, manually rotate the control rod 66 to drive the screw 65 to rotate in the opposite direction. When the screw 65 rotates, the slider 67 on its external threaded sleeve immediately presses the guide rod 68 to slide up and drives the pawl block 610 installed through the connecting rod 69 to slide up and embed into the ratchet groove of the ratchet 63 to resist and limit, so that the ratchet 63 is restricted and cannot drive the rotating rod 6 to rotate, thereby improving the stability of use after adjustment.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
