Description

Technical Field

[0001] This utility model specifically relates to an aerogel fiber roll rewinding device with a side guide plate. Background Technology

[0002] Aerogel fiber rolls are flexible thermal insulation materials made primarily of silica aerogel, combined with fiber reinforcement through a special processing technique. Due to their ultra-low thermal conductivity, wide temperature range adaptability, Class A fire resistance, and excellent hydrophobic properties, they are widely used in key areas such as industrial pipeline insulation, LNG cryogenic insulation, and high-end building energy conservation. Rewinding is an indispensable and crucial process in the production, testing, and finished product packaging of these rolls.

[0003] Currently, the unwinding operation of aerogel fiber rolls has gradually shifted from manual operation to mechanized equipment. Existing unwinding equipment mostly draws on general roll winding technology and mainly consists of an unwinding mechanism, a winding roller, a drive motor, and a tension control component.

[0004] Currently, while aerogel fiber rolls possess a certain degree of flexibility, their fiber structure remains fragile. Factors such as roll width tolerances, equipment installation parallelism deviations, or uneven wear of guide rollers can easily cause the roll to shift to one side during unwinding. Existing methods mostly rely on manual positioning or fixed limiting plates for initial constraint, failing to dynamically adjust based on real-time roll offset. This severely impacts subsequent cutting and on-site installation sealing and insulation performance. Furthermore, the widths of different aerogel roll specifications vary significantly, and existing guide components are mostly designed with fixed dimensions, requiring disassembly and reassembly when changing roll specifications, which is time-consuming.

[0005] Therefore, it is necessary to invent an aerogel fiber roll rewinding device with a side guide plate to solve the above problems. Utility Model Content

[0006] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes an aerogel fiber roll rewinding device with a side guide plate.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an aerogel fiber roll unwinding device with side guide plates, including a base, fixed plates extending upward from both sides of the top of the base, a control box installed on the outer side of one side of the fixed plate, two sets of unwinding rollers between the two sets of unwinding rollers, an aerogel fiber roll placed between the two sets of unwinding rollers, and a positioning guide assembly fixed on the top of the two side fixed plates. The aerogel fiber roll is equipped with a positioning rod inside; The positioning and guiding assembly includes a mounting plate fixed to the top of the fixed plate. A positioning groove is formed in the middle of the mounting plate, and a connecting rod is installed in the positioning groove. One end of the connecting rod is connected to the positioning rod, and a locking plate is installed on the outside of the other end. Fastening bolts are provided on both sides of the connecting rod on the locking plate. Multiple sets of fastening grooves are provided on both sides of the positioning groove on the mounting plate, and the fastening bolts are fixed in the fastening grooves. Two symmetrically arranged guide blocks are also installed on the inner side of the mounting plate. The two guide blocks are respectively installed on the inner side of the fastening grooves on both sides of the positioning groove. A guide plate is installed in the guide block. Multiple springs are installed between the bottom of the guide plate and the bottom of the inner side of the guide block. The multiple springs press one side of the guide plate against the side of the aerogel fiber roll.

[0008] Preferably, the positioning rod has positioning screw holes at both ends, the end of the docking rod is docked and fixed with the positioning screw holes, the other end of the docking rod is externally connected to the rotating ring in the middle of the locking plate, and the end of the docking rod is provided with a rotating disk outside the locking plate.

[0009] Preferably, the locking plate is provided with a through hole that matches the fastening bolt, the fastening bolt passes through the through hole and the fastening groove, and its end is fixed by a fastening nut.

[0010] Preferably, the guide block has multiple sets of studs that match the fastening groove on one side, one end of the studs is fixed by a nut, the guide block has a telescopic groove inside, a limiting frame is provided at the opening of the telescopic groove, the bottom edge of the guide plate has a limiting strip that matches the limiting frame, and the end of the guide plate moves within the telescopic groove.

[0013] Preferably, the top of the positioning groove is open, and the tops of the multiple sets of fastening grooves are all closed.

[0014] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: 1. The positioning rod inside the aerogel fiber roll of this utility model forms a precise connection with the docking rod in the positioning guide assembly. In particular, the positioning screw holes at both ends of the positioning rod and the threaded engagement of the docking rod can firmly fix the roll on the preset rewinding axis. During the rewinding process, the roll always rotates around the fixed axis, ensuring the cylindricity and flatness of the roll after rewinding, and avoiding uneven edges of the roll caused by axis offset. 2. The guide plate inside the guide block of this utility model achieves flexible support through springs, which can always closely fit the side of the roll material and form a continuous and appropriate lateral limiting force.

[0019] This utility model provides, for example Figure 1-5The aerogel fiber roll unwinding device with side guide plates shown includes a base 1, fixed plates 11 extending upward from the top of the base 1 on both sides, a control box 2 installed on the outer side of one side fixed plate 11, two sets of unwinding rollers 12 between the two sides fixed plates 11, an aerogel fiber roll 3 placed between the two sets of unwinding rollers 12, and a positioning guide assembly 4 fixed on the top of the two sides fixed plates 11. Specifically, a positioning rod 31 is installed inside the aerogel fiber roll 3; Specifically, the positioning guide assembly 4 includes a mounting plate 41 fixed to the top of the fixing plate 11. A positioning groove 411 is provided in the middle of the mounting plate 41. A connecting rod 42 is installed in the positioning groove 411. One end of the connecting rod 42 is connected to the positioning rod 31, and a locking plate 43 is installed on the outside of the other end. Fastening bolts 44 are provided on the locking plate 43 on both sides of the connecting rod 42. Multiple sets of fastening grooves 412 are provided on both sides of the positioning groove 411 on the mounting plate 41. The fastening bolts 44 are fixed in the fastening grooves 412. Two symmetrically arranged guide blocks 45 are also installed on the inner side of the mounting plate 41. The two guide blocks 45 are respectively installed on the inner side of the fastening grooves 412 on both sides of the positioning groove 411. A guide plate 46 is installed in the guide block 45. Multiple springs 47 are installed between the bottom of the guide plate 46 and the bottom of the inner side of the guide block 45. The multiple springs 47 press one side of the guide plate 46 against the side of the aerogel fiber roll 3.

[0020] Specifically, the positioning rod 31 has positioning screw holes 32 at both ends, the end of the docking rod 42 is docked and fixed with the positioning screw holes 32, the other end of the docking rod 42 is connected to the rotating ring 431 in the middle of the locking plate 43, and the end of the docking rod 42 is provided with a rotating disk 421 located outside the locking plate 43.

[0021] Specifically, the locking plate 43 is provided with a through hole 432 for matching fastening bolt 44. The fastening bolt 44 passes through the through hole 432 and the fastening groove 412, and its end is fixed by a fastening nut 441.

[0022] Specifically, the guide block 45 has multiple sets of studs 451 with matching fastening grooves 412 on one side. One end of the stud 451 is fixed by a nut. The guide block 45 has a telescopic groove 452 inside. A limiting frame 453 is provided at the opening of the telescopic groove 452. A limiting strip 461 matching the limiting frame 453 is provided at the bottom edge of the guide plate 46. The end of the guide plate 46 moves within the telescopic groove 452.

[0023] Specifically, an arc-shaped plate 462 extends from one side of the moving surface of the guide plates 46 on both sides, and the arc-shaped plates 462 on both sides are symmetrically arranged.

[0024] Specifically, both guide blocks 45 are installed above the docking rod 42, and the guide plate 46 contacts the winding end of the aerogel fiber roll 3.

[0025] Specifically, the top of the positioning groove 411 is open, and the tops of the multiple fastening grooves 412 are all closed.

[0026] In this embodiment, the base 1 is placed on a horizontal and stable working surface, ensuring that the bottom of the base 1 is in contact with the ground without shaking. Then, the two fixing plates 11 are extended upward along the preset installation position on the top of the base 1 and fixed by welding or high-strength bolts to ensure the connection strength between the fixing plates 11 and the base 1, and to avoid structural displacement during the subsequent roll-up process.

[0027] Specifically, on the outer side of one side fixing plate 11, according to the installation dimensions of the control box 2, it is fixed to the preset mounting bracket on the fixing plate 11 with bolts. At the same time, the wiring connection between the internal circuit of the control box 2 and the drive assembly of the rewinding roller 12 is completed, ensuring that the speed and direction of the rewinding roller 12 can be adjusted through the control box 2 after the equipment is powered on. Then, the two sets of rewinding rollers 12 are installed in parallel in the bearing seats between the two side fixing plates 11, and the spacing of the rewinding rollers 12 is adjusted to meet the placement requirements of the aerogel fiber roll 3, and the rewinding rollers 12 rotate without jamming or abnormal noise.

[0028] Specifically, the mounting plate 41 is fixed to the top of the two side fixing plates 11 with bolts, ensuring that the mounting plate 41 is horizontal and parallel to the axis of the rewinding roller 12. The connecting rod 42 is placed in the positioning groove 411 in the middle of the mounting plate 41. According to the position of the positioning rod 31 inside the aerogel fiber roll 3, the extension length of the connecting rod 42 is adjusted so that one end of the connecting rod 42 can be accurately inserted into the positioning screw holes 32 at both ends of the positioning rod 31. The connecting rod 42 and the positioning rod 31 are fixedly connected by threaded connection.

[0029] Specifically, a locking plate 43 is fitted onto the other end of the connecting rod 42, allowing the connecting rod 42 to pass through the rotating ring 431 in the middle of the locking plate 43, ensuring that the connecting rod 42 can rotate freely within the rotating ring 431. Then, fastening bolts 44 are inserted into the through holes 432 on both sides of the connecting rod 42 on the locking plate 43. Based on the final position of the connecting rod 42, suitable fastening grooves 412 on both sides of the positioning groove 411 on the mounting plate 41 are selected. The fastening bolts 44 are passed through the through holes 432 and inserted into the fastening grooves 412. Fastening nuts 441 are tightened at the ends of the fastening bolts 44 until the locking plate 43 and the mounting plate 41 are tightly fitted, thus locking the position of the connecting rod 42.

[0030] Specifically, two guide blocks 45 are placed inside the mounting plate 41 and inside the fastening grooves 412 on both sides of the positioning groove 411, respectively. Multiple sets of studs 451 on one side of the guide block 45 are aligned with the corresponding mounting holes on the mounting plate 41. The studs 451 are then fixed with nuts, connecting the guide block 45 to the mounting plate 41. A guide plate 46 is placed inside the telescopic groove 452 within the guide block 45, ensuring that the limiting strip 461 at the bottom edge of the guide plate 46 is embedded in the limiting frame 453 at the opening of the telescopic groove 452, preventing the guide plate 46 from detaching from the telescopic groove 452 during movement. Finally, multiple springs 47 are installed between the bottom of the guide plate 46 and the bottom of the inner side of the guide block 45. In their natural state, the springs 47 generate an upward elastic force, pushing the guide plate 46 upward, allowing one side of the guide plate 46 to tightly adhere to the side of the aerogel fiber roll 3. Simultaneously, the end of the guide plate 46 can move flexibly within the telescopic groove 452 to adapt to changes in the diameter of the aerogel fiber roll 3.

[0031] Specifically, the aerogel fiber roll 3, pre-mounted with positioning rods 31, is placed between two sets of rewinding rollers 12. The position of the roll is adjusted so that the two ends of the positioning rods 31 are aligned with the positions of the two connecting rods 42. Then, by rotating the rotating disk 421 at the end of the connecting rod 42, the connecting rod 42 is rotated, so that the connecting rod 42 is precisely connected with the positioning screw hole 32 of the positioning rod 31 and tightened, thus completing the initial positioning of the aerogel fiber roll 3.

[0032] Specifically, observe the fit between the guide plate 46 and the side of the aerogel fiber roll 3. If the fit is too loose or too tight, the position of the guide block 45 can be finely adjusted by adjusting the tightness of the nut on the stud 451 of the guide block 45 to ensure that the guide plate 46 always maintains a suitable fit with the side of the roll under the action of the spring 47. At the same time, the arc-shaped plates 462 extending from the guide plates 46 on both sides can effectively wrap and guide the roll end of the roll.

[0033] Specifically, by controlling the control box 2 to set the rotation speed and rewinding direction of the rewinding roller 12, after starting the equipment, the rewinding roller 12 begins to rotate, driving the aerogel fiber roll 3 to perform the rewinding operation. During the rewinding process, the cooperation between the connecting rod 42 and the positioning rod 31 ensures that the roll always rotates around a fixed axis to avoid deviation; under the elastic force of the spring 47, the guide plate 46 always sticks to the side of the roll, guiding and limiting the side of the roll to prevent wrinkles, deviations, and other problems from occurring on the side of the roll. At the same time, the guide plate 46 can automatically move downward in the expansion groove 452 as the diameter of the roll decreases, continuously maintaining the guiding effect.

[0034] Specifically, after the aerogel fiber roll 3 is unwound, the unwound roller 12 is stopped by controlling the machine housing 2. Then, the fastening nut 441 on the locking plate 43 is loosened, and the locking plate 43 is pushed to drive the docking rod 42 to disengage from the positioning screw hole 32 of the positioning rod 31. Finally, the unwound aerogel fiber roll 3 is taken out from between the two sets of unwound rollers 12, completing one unwound operation.

[0035] In this embodiment, the device achieves precise positioning and guidance of the aerogel fiber roll 3 through the positioning guide component 4: the threaded connection between the connecting rod 42 and the internal positioning rod 31 of the roll ensures that the roll always rotates around a fixed axis during the unwinding process, avoiding irregular unwinding of the roll due to axis deviation; the guide plates 46 on both sides are tightly pressed against the side of the roll under the action of the spring 47, which can effectively limit the lateral displacement of the roll and prevent problems such as wrinkles and unevenness on the side of the roll. It is especially suitable for materials such as aerogel fiber that are brittle and easily damaged, and significantly improves the appearance quality and dimensional accuracy of the roll after unwinding. The positioning groove 411 has an open top, which facilitates the installation and position adjustment of the connecting rod 42, while the closed top design of the multiple fastening grooves 412 can prevent the fastening bolts 44 from coming out from the top during installation. At the same time, it provides multiple installation positions to accommodate aerogel fiber rolls 3 with different lengths of positioning rods 31, improving the versatility of the device.

[0036] In this embodiment, the guide block 45 is detachably connected to the mounting plate 41 via studs 451, and the limiting strip 461 at the bottom of the guide plate 46 cooperates with the limiting frame 453 of the guide block 45, ensuring the stability of the guide plate 46's movement and facilitating the maintenance and replacement of the guide plate 46 and spring 47. The rotating disk 421 at the end of the docking rod 42 allows the operator to easily rotate the docking rod 42 to dock or separate it from the positioning rod 31, reducing the difficulty of operation. The control box 2 integrates the speed and direction control functions of the rewinding roller 12. The operator can precisely adjust the rewinding speed according to the thickness, material, and other parameters of the aerogel fiber roll 3, avoiding damage to the roll due to excessive speed or affecting work efficiency due to excessively slow speed, effectively improving the automation and work efficiency of the rewinding operation.

[0037] In this embodiment, the elastic support design of the spring 47 enables the guide plate 46 to have automatic adjustment capability, which can adapt to the change in the diameter of the roll during the rewinding process and always maintain effective contact with the side of the roll. This eliminates the need for frequent manual adjustments by operators, reduces human intervention, and avoids squeezing damage to the side of the roll caused by rigid contact.

[0038] In this embodiment, all components of the equipment are detachably connected. When a component is worn or malfunctions, it can be disassembled and replaced individually without replacing the entire equipment, thus reducing maintenance costs and extending the overall service life of the equipment. In addition, the arc-shaped plate 462 extending from the guide plate 46 can provide a smooth guide to the winding end of the roll material, avoiding edge collisions during winding and further protecting the integrity of the aerogel fiber roll material 3.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
