Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0040] like Figures 1-10 As shown, this utility model discloses a single crystal furnace insulation felt wrapping device, including a first support module 100a, a second support module 100b, two guide modules 200, a limiting module 300, a pressing module 400, a cylinder wrapping module 500, and a cutting module 600. Soft insulation felt is placed on the first support module 100a, and hard insulation felt is placed on the second support module 100b. After being guided apart by the first support module 100a and the second support module 100b respectively, the soft and hard insulation felts are led out through the corresponding side guide modules 200, and then sequentially pass through the limiting module 300 and the pressing module 400 before being wrapped onto the insulation cylinder on the cylinder wrapping module 500.

[0041] The first support module 100a and the second support module 100b are structurally identical, both including a felt-laying frame 101. A horizontally arranged felt-laying disc 102 is rotatably mounted on the felt-laying frame 101, and an air-expansion shaft 103 is coaxially mounted at the top center of the felt-laying disc 102. The felt-laying frame 101 is equipped with a drive source for driving the felt-laying disc 102 to rotate. The drive source includes a motor mounted on the felt-laying frame 101, and a pulley is coaxially connected to the motor shaft and the bottom of the felt-laying disc 102, with the two pulleys providing belt drive.

[0042] The guide module 200 includes a guide bracket 201. A vertically arranged inlet roller 202 and an outlet roller 205 are rotatably mounted on the guide bracket 201. A limiting adjustment seat 203 connected to the guide bracket 201 is provided at the bottom of the inlet roller 202. The limiting adjustment seat 203 limits the bottom edge of the insulation felt entering the guide module 200 so that the bottom of the insulation felt is flush with the surface of the roll-up module 500 where the insulation cylinder is placed.

[0043] A tension detection assembly is provided on the guide bracket 201 between the inlet roller 202 and the outlet roller 205 to detect the tension of the insulation felt. The tension detection assembly includes a tension detection bracket 204 mounted on the guide bracket 201, with two tension sensors 209 mounted on the tension detection bracket 204. A tension detection roller 208 is rotatably mounted between the two tension sensors 209. The tension detection roller 208 is vertically arranged and its two ends are rotatably connected to the two tension sensors 209 respectively. When the insulation felt passes through the guide module 200, it enters through the inlet roller 202, wraps around the tension detection roller 208, and is then exited by the outlet roller 205. The relative positions of the inlet roller 202, the outlet roller 205, and the tension detection roller 208 are controlled so that the wrap angle of the insulation felt with respect to the tension detection roller 208 is greater than 180 degrees. When the insulation felt wraps around the tension detection roller 208, the tension of the insulation felt is monitored by the tension sensors 209 at both ends of the tension detection roller 208.

[0044] A clamping assembly is provided on the guide bracket 201 on the side of the output roller 205. The clamping assembly can cooperate with the output roller 205 to clamp the insulation felt. The clamping assembly includes a sliding roller 206 vertically arranged on the side of the output roller 205. The two ends of the sliding roller 206 are rotatably connected to the guide bracket 201 and also slidably connected. The sliding of the sliding roller 206 can change the distance between it and the output roller 205. The guide bracket 201 is also provided with a first cylinder 207 to drive the sliding roller 206 to slide. When the cutting module 600 cuts the insulation felt, one side of the insulation felt is rolled up on the insulation cylinder for fixation, and the other side is clamped and fixed by the clamping assembly, which facilitates the cutting of the insulation felt in a taut state.

[0045] The limiting module 300 includes a base 301, on which a horizontally arranged lower limiting plate 302 is provided. Side plates 303 are vertically arranged on both sides of the lower limiting plate 302, and the side plates 303 are parallel to each other. An upper limiting plate 304 is provided between the side plates 303. The lower limiting plate 302 and the upper limiting plate 304 are funnel-shaped on the side closest to the guide module 200, that is, the side of the lower limiting plate 302 on the side closest to the guide module 200 is bent downwards, and the side of the upper limiting plate 304 on the side closest to the guide module 200 is bent upwards.

[0046] The upper limit plate 304 is provided with a horizontally arranged adjusting screw 305 perpendicular to the side plate 303. The top of each side plate 303 is provided with a downwardly extending adjusting groove 307. The two ends of the adjusting screw 305 slide in the adjusting grooves 307 of the side plate 303 respectively. The two ends of the adjusting screw 305 are threadedly connected to locking nuts 306 that mate with the outer walls of the side plate 303. When the two locking nuts 306 are tightened and the distance between them matches the distance between the outer walls of the side plates 303, the locking nuts 306 press against the side plates 303 to fix the upper limit plate 304. Loosening the locking nuts 306 will prevent them from pressing against the side plates 303, and the height position of the upper limit plate 304 between the two side plates 303 can be adjusted. By cooperating with the locking nut 306 and the adjusting screw 305, the distance between the upper limit plate 304 and the lower limit plate 302 can be adjusted to match the specifications of the insulation felt, and the limit module 300 prevents the insulation felt from moving up and down during the transportation process.

[0047] The clamping module 400 includes a clamping bracket 401, on which a rotating bracket 402 is rotatably mounted. The rotating shaft of the rotating bracket 402 is vertical. A second cylinder 404 is hinged to the clamping bracket 401. The piston rod of the second cylinder 404 is hinged to the rotating bracket 402. The extension and retraction of the second cylinder 404 can drive the rotating bracket 402 to swing. A clamping roller 403 is rotatably mounted at the end of the rotating bracket 402 away from the clamping bracket 401. The clamping roller 403 is arranged vertically.

[0048] The coil wrapping module 500 includes a wrapping support 501, a horizontal wrapping platform 502 rotatably mounted on the wrapping support 501, and a drive source for driving the wrapping platform 502 to rotate on the wrapping support 501. The drive source includes a motor mounted on the wrapping support 501, and a pulley is coaxially connected to the motor shaft and the bottom of the wrapping platform 502, with the two pulleys driving the belt.

[0049] A centering assembly 503 is provided on the top of the felt-wrapping platform 502. The centering assembly 503 fixes the insulation cylinder and makes the insulation cylinder and the felt-wrapping platform 502 coaxial. The centering assembly 503 includes three electric push rods that are equally spaced in a circular trajectory around the rotation axis of the felt-wrapping platform 502. The end of the electric push rod is provided with a top block. The extension and retraction direction of the electric push rod is radial along its circular trajectory.

[0050] The cutting module 600 includes a mounting base 601, on which a vertically rotatable lifting guide rail 602 is mounted. The lifting guide rail 602 has a vertically arranged rotating rod rotatably connected to the mounting base 601. The mounting base 601 is provided with a drive source for driving the rotating rod to rotate. The drive source includes a motor mounted on the mounting base 601, and a reduction gearbox is connected between the motor and the rotating rod. The operation of the motor drives the rotating rod to rotate, and the rotating rod drives the lifting guide rail 602 to swing around the rotating rod.

[0051] A vertically movable slide block 603 is slidably mounted on the lifting guide rail 602. The slide block 603 is equipped with a drive source for driving the slide block 603 to move vertically. The drive source includes a motor mounted on the slide block 603. A gear located inside the lifting guide rail 602 is coaxially connected to the motor shaft. A rack meshing with the gear is vertically mounted inside the lifting guide rail 602. The operation of the motor drives the gear to rotate, and the gear moves on the rack to drive the slide block 603 to move up and down.

[0052] The slide 603 is also equipped with a horizontally arranged cutting seat 604. A drive sheave and a driven sheave are rotatably mounted on the cutting seat 604. A tensioned annular diamond wire 607 is fitted between the drive and driven sheaves. A motor is correspondingly mounted on the cutting seat 604 to drive the drive sheave. The motor drives the drive sheave to rotate, and the movement of the annular diamond wire 607 achieves the cutting of the insulation felt. The cutting seat 604 is also equipped with a dust suction hood 605, which covers the range of motion of the annular diamond wire 607. A dust suction pipe 606 is connected to the top of the dust suction hood 605, and the dust suction pipe 606 is connected to a dust collection device.

[0053] When wrapping the insulation felt, the insulation cylinder is placed on the wrapping platform 502, and the three electric push rods of the centering component 503 extend and retract synchronously with the same stroke, so that the top block contacts the inner wall of the insulation cylinder, thereby positioning and fixing the insulation cylinder. The soft insulation felt is placed on the first bearing module 100a, and the hard insulation felt is placed on the second bearing module 100b. After being guided apart by the first bearing module 100a and the second bearing module 100b respectively, the soft and hard insulation felts enter the corresponding side guide modules 200, pass around the guide modules 200, and are then wrapped onto the insulation cylinder by the limiting module 300. The second cylinder 404 drives the rotating bracket 402 to swing, causing the pressure roller 403 to press on the insulation felt, thus tensioning the insulation felt. The felt-wrapping platform 502 rotates, and the felt-releasing disc 102 of the corresponding first bearing module 100a or second bearing module 100b rotates to release the soft or hard insulation felt, thereby wrapping the insulation felt of the insulation cylinder. During this process, the tension detection roller 208 detects the real-time tension of the insulation felt. The felt-wrapping platform 502 and the felt-releasing disc 102 can adjust their rotation speed to control the tension. The pressing module 400 can also adjust the swing amplitude of the rotating bracket 402 to adjust the pressure of the pressing roller 403 on the insulation felt, thereby achieving tension adjustment.

[0054] When the insulation cylinder is wrapped with insulation felt, during the first layer of insulation felt, the rotating bracket 402 rotates to make the pressing roller 403 press the insulation felt tightly onto the insulation cylinder, so that the insulation felt and the insulation cylinder are in close contact. After the insulation felt is wrapped to the second layer, the insulation felt tension is formed. The rotating bracket 402 swings outward away from the insulation cylinder, so that the pressing roller 403 presses on the insulation felt to make it taut. At this time, the continuous felt wrapping state is entered.

[0055] When the insulation felt needs to be cut, the wrapping process is stopped, and the clamping assembly clamps the insulation felt. At this time, the insulation felt is still under tension. The lifting guide rail 602 swings so that the cutting line is above the cutting point of the insulation felt. Then, while the annular diamond wire 607 moves, the slide 603 descends, allowing the annular diamond wire 607 to cut the insulation felt. During this process, the suction pipe 606 sucks up the dust generated during the cutting process, reducing the impact on the environment and personnel health.

[0056] In this embodiment, soft insulation felt is placed on the first supporting module 100a, and hard insulation felt is placed on the second supporting module 100b. Different types of insulation felt can also be used depending on the wrapping requirements. In short, this solution can wrap two types of insulation felt. During wrapping, two types of insulation felt can be wrapped simultaneously, or one insulation felt can be cut during the wrapping process while the other continues wrapping, and then both insulation felts can be wrapped again subsequently, achieving the switching wrapping operation between different types of insulation felt.

[0057] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
