Technical Field

[0001] The utility model relates to the technical field of preoxidized silk felt production, in particular to a positioning device used for preoxidized silk felt production. Background Art

[0002] Pre-oxidized fiber mat is a high-performance material widely used in aerospace, automotive, construction, and other fields. As these industries continue to develop, the quality and production requirements for pre-oxidized fiber mat are also increasing. The production of pre-oxidized fiber mat involves multiple complex processes, such as fiber carding, layup, needling, and hot pressing. These processes are closely linked, and problems in any of them can affect the quality of the final product.

[0003] Although some existing mechanical positioning devices have improved the positioning accuracy to a certain extent, they still have some limitations. Some positioning devices have poor versatility and can only be used for the production of pre-oxidized fiber felt of a specific size or type. When the product specifications change, the positioning device needs to be adjusted a lot or even some components need to be replaced, which increases production costs and production preparation time. Utility Model Content

[0004] The purpose of the present invention is to provide a positioning device for the production of pre-oxidized fiber felt, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning device for the production of preoxidized wire felt, comprising a support plate, a preoxidized wire felt roller flattening portion, and an adjustment and positioning portion, wherein a support rod is fixedly installed on the bottom outer wall of the support plate, and a support pad is fixedly installed on the other end of the support rod; the preoxidized wire felt roller flattening portion is arranged on the top of the support plate; and the adjustment and positioning portion is arranged on the top of the preoxidized wire felt roller flattening portion.

[0006] Preferably, the pre-oxidized silk felt roller flattening part specifically includes: a workbench, fixedly installed on the top of the support plate; a placement groove is opened on the workbench, rectangular grooves are opened on the outer walls of both sides of the workbench, and positioning slide rods are fixedly installed between the inner walls of the rectangular grooves, and a workbench is set up, which provides a stable support platform for the pre-oxidized silk felt.

[0007] Preferably, a rectangular slider is movably mounted on the positioning slide bar, and the rectangular slider is slidably mounted inside the rectangular groove. A rotating rod is rotatably connected between the rectangular sliders, and a roller is movably mounted on the rotating rod.

[0008] Preferably, the outer wall of the drum is provided with grooves equidistantly spaced around its circumference, a push handle is fixedly mounted on one outer wall of the rectangular slider, and a slide rail is fixedly mounted on the top of the workbench. The drum is provided so that during the rolling process, the pressure exerted by the drum can compact the fibers in the pre-oxidized felt, making the surface of the felt smoother and flatter. This helps to reduce voids within the felt and improve its overall uniformity.

[0009] Preferably, positioning slots are equidistantly provided on the slide rail, an adjusting slider is slidably connected to the interior of the slide rail, a circular hole is provided on the adjusting slider, a rotating shaft is movably installed inside the circular hole, supporting connecting plates are fixedly installed at both ends of the rotating shaft, a card block is fixedly installed between the supporting connecting plates, the card block is engaged with the positioning slot, and a slide rail is provided. The positioning adjustment slide rail provides a precise adjustment track for the positioning device, and the operator can move the adjusting slider through the slide rail to accurately move to the specified position according to the specific requirements of the pre-oxidized silk felt production.

[0010] Preferably, the adjustment positioning part specifically includes: a support block, which is fixedly installed between the adjustment sliders; a rectangular through groove is opened on the support block, a sliding block is movably sleeved on the outer wall of the support block, a threaded sleeve is fixedly installed on the sliding block, and a threaded rod is threadedly connected to the threaded sleeve.

[0011] Preferably, a handwheel is fixedly installed on the top of the threaded rod, and the other end of the threaded rod movably passes through the top of the sliding block and extends to the bottom of the sliding block.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1

[0024] The preferred embodiment of the positioning device for preoxidized fiber felt production provided by the utility model is as follows Figure 1-4 Shown: A positioning device for preoxidized silk felt production, comprising a support plate 1, a preoxidized silk felt roller flattening portion 2, and an adjustment and positioning portion 3. A support rod 4 is fixedly mounted on the bottom outer wall of the support plate 1, and a support pad is fixedly mounted on the other end of the support rod 4; the preoxidized silk felt roller flattening portion 2 is arranged on the top of the support plate 1; the adjustment and positioning portion 3 is arranged on the top of the preoxidized silk felt roller flattening portion 2.

[0025] The preoxidized silk felt roller flattening part 2 specifically includes: a workbench 211, which is fixedly installed on the top of the support plate 1; a placement groove 214 is opened on the workbench 211, and rectangular grooves are opened on the outer walls of both sides of the workbench 211, and positioning slide rods 212 are fixedly installed between the inner walls of the rectangular grooves.

[0026] A rectangular slider 2111 is movably mounted on the positioning slide bar 212 . The rectangular slider 2111 is slidably mounted inside the rectangular groove. A rotating rod 2112 is rotatably connected between the rectangular sliders 2111 . A roller 2113 is movably mounted on the rotating rod 2112 .

[0027] The outer wall of the drum 2113 is provided with grinding grooves at equal intervals around its circumference. A push armrest 219 is fixedly mounted on the outer wall of one side of the rectangular slider 2111 , and a slide rail 213 is fixedly mounted on the top of the workbench 211 .

[0028] Positioning slots are equidistantly provided on the slide rail 213, and an adjusting slider 215 is slidably connected inside the slide rail 213. A circular hole is provided on the adjusting slider 215, and a rotating shaft 218 is movably installed inside the circular hole. Support connecting plates 217 are fixedly installed at both ends of the rotating shaft 218, and a card block 216 is fixedly installed between the support connecting plates 217, and the card block 216 is engaged with the positioning slot.

[0029] During the process of this embodiment, the workbench 211 provides a stable platform for the entire paving operation, and the placement groove 214 can be used to place the silk felt body. When the pre-oxidized silk felt is placed, the rectangular slider 2111 is pushed by pushing the armrest 219. When the rectangular slider 2111 slides on the positioning slide bar 212, it drives the roller 2113 to stretch and flatten the pre-oxidized silk felt through the rotating rod 2112, which can effectively eliminate wrinkles. This helps to produce pre-oxidized silk felt products with a smooth surface and uniform thickness, improve the quality and appearance consistency of the product, and the pre-oxidized silk felt after being processed by the roller paving part is in a flat and stretched state, which enables the positioning device to position it more accurately and quickly.

[0030] Example 2

[0031] On the basis of Example 1, a preferred embodiment of a positioning device for preoxidized felt production provided by the present invention is as follows: Figure 1-4 As shown: the adjustment and positioning part 3 specifically includes: a support block 311, which is fixedly installed between the adjustment sliders 215; a rectangular through groove 312 is opened on the support block 311, and a sliding block 3112 is movably sleeved on the outer wall of the support block 311, and a threaded sleeve 315 is fixedly installed on the sliding block 3112, and a threaded rod 314 is threadedly connected to the threaded sleeve 315.

[0032] A handwheel 313 is fixedly installed on the top of the threaded rod 314, and the other end of the threaded rod 314 can move through the top of the sliding block 3112 and extend to the bottom of the sliding block 3112. The threaded rod 314 is arranged inside the rectangular through groove 312, and a circular slide groove 316 is opened on the threaded rod 314. The inside of the circular slide groove 316 is slidably connected to the slide rod 317, and the other end of the slide rod 317 is fixedly connected to the fixed block 319.

[0033] A rubber positioning block 3111 is fixedly installed at the bottom of the fixed block 319, and strip grooves are equidistantly provided on the bottom outer wall of the rubber positioning block 3111. A spring 318 is movably sleeved on the outer wall of the sliding rod 317. One end of the spring 318 is fixedly connected to the bottom outer wall of the sliding block 3112, and the other end of the spring 318 is fixedly connected to the top outer wall of the fixed block 319.

[0034] When the cam 314 is in the process of being moved to the desired position, the hand wheel 313 is manually turned to rotate the threaded rod 314. When the threaded rod 314 rotates, it moves downward on the threaded sleeve 315, and then drives the rubber positioning block 3111 to contact the pre-oxidized wire felt through the fixed block 319. When the rubber positioning block 3111 contacts the pre-oxidized wire felt, the spring 318 will play a buffering role, which can not only ensure that the rubber positioning block 3111 is in close contact with the wire felt to realize the positioning function, but also avoid damage to the pre-oxidized wire felt due to excessive extrusion. It can be flexibly adjusted according to the specifications of the pre-oxidized wire felt actually produced. Whether it is width, length or special shape of the wire felt, it can be accurately positioned. When producing narrow pre-oxidized wire felt, the positioning part can be adjusted to the appropriate spacing of the relevant components of the positioning device to ensure that the wire felt is accurately located in the center position on the production line and reduce edge deviation.

[0035] Working principle: The workbench 211 provides a stable platform for the entire paving operation, and the placement groove 214 can be used to place the silk felt body. When the pre-oxidized silk felt is placed, the rectangular slider 2111 is pushed by pushing the handrail 219. When the rectangular slider 2111 slides on the positioning slide bar 212, it drives the roller 2113 to stretch and flatten the pre-oxidized silk felt through the rotating rod 2112, which can effectively eliminate wrinkles and can adapt to the paving needs of pre-oxidized silk felts of different widths. Then, according to the size of the pre-oxidized silk felt, manually push the adjusting slider 215 to make the adjusting slider 215 slide on the slide rail 213. When the adjusting slider 215 moves to the appropriate position, it is connected to the positioning card through the card block 216. The grooves are engaged to fix the position of the adjustment slider 215, and then the sliding block 3112 is driven to slide on the supporting connecting plate 217 according to the size of the pre-oxidized wire felt. When the sliding block 3112 is moved to the desired position, the hand wheel 313 is manually turned to rotate the threaded rod 314. When the threaded rod 314 rotates, it moves downward on the threaded sleeve 315, and then the rubber positioning block 3111 is driven to contact the pre-oxidized wire felt through the fixed block 319. When the rubber positioning block 3111 contacts the pre-oxidized wire felt, the spring 318 will play a buffering role, which can not only ensure that the rubber positioning block 3111 is in close contact with the wire felt to realize the positioning function, but also avoid damage to the pre-oxidized wire felt due to excessive extrusion.
