[0056] In one embodiment, the chassis turntable 10 is used to connect the tooling installation component 20 and the tooling rotating component 30, and provide an installation base for the tooling installation component 20. In this embodiment, the chassis turntable 10 is a rectangular plate-like structure, and two tooling installation components 20 are arranged in parallel to the chassis turntable 10, which effectively improves the compactness of the fixing device.

[0058] The base 32 is disposed below the chassis turntable 10. In this embodiment, the base 32 is a hollow tubular structure, and a flange is disposed at the lower end of the base 32 to facilitate fixing the base 32. For example, it is convenient to fix the base 32 to the mounting platform 200. The transmission assembly is rotationally matched with the base 32, and the transmission assembly is connected to the first drive assembly 31 and the chassis turntable 10. After the base 32 is installed in place, the lower end of the base 32 is connected to the ground or the mounting platform 200, and the base 32 is in a stationary state.

[0059] In one embodiment, the first reducer is a helical gear reducer, the first drive motor is arranged horizontally, the input shaft of the helical gear reducer is arranged horizontally, and the output shaft of the helical gear reducer is arranged vertically. Of course, the specific type of the first reducer is not limited thereto, and is determined according to actual needs.

[0060] In one embodiment, the transmission assembly includes a rotating shaft (not shown), which is rotatably disposed in the base 32, the rotating shaft is coaxially disposed with the base 32, and the lower end of the rotating shaft is connected to the first driving assembly 31. Specifically, the lower end of the rotating shaft is connected to the output shaft of the first reducer, and the upper end of the rotating shaft is connected to the bottom of the base turntable 10.

[0061] In one embodiment, the transmission assembly further includes a connecting member 33, which is a hollow tubular structure. The connecting member 33 is coaxially arranged with the base 32, that is, the central axis of the connecting member 33 is in the same straight line as the central axis of the base 32. The outer diameter of the connecting member 33 is smaller than the outer diameter of the base 32, and the upper end of the connecting member 33 is connected to the bottom of the base turntable 10. Specifically, the upper end of the connecting member 33 is welded to the bottom of the base turntable 10. Of course, the upper end of the connecting member 33 and the bottom of the base turntable 10 can also be integrally formed or connected by bolts. The lower end of the connecting member 33 is detachably connected to the upper end of the rotating shaft to facilitate maintenance of the workpiece fixing device of the rotary felt equipment.

[0062] In one embodiment, a first flange 34 is provided at the lower end of the connecting member 33, a second flange 35 is provided at the upper end of the rotating shaft, and the first flange 34 and the second flange 35 are connected by bolts. Specifically, the outer diameter of the first flange 34 is equal to the outer diameter of the second flange 35, the first flange 34 and the second flange 35 are coaxially arranged, the lower end of the connecting member 33 is welded to the first flange 34, and the upper end of the rotating shaft is welded to the second flange 35. The first flange 34 and the second flange 35 are both provided with a plurality of through holes, the through holes of the first flange 34 correspond to the through holes of the second flange 35 one by one, and the first flange 34 and the second flange 35 are connected by bolts in the through holes.

[0063] In one embodiment, the transmission assembly further includes a rotating connection member 36, which is sleeved on the outer periphery of the rotating shaft and is located between the bottom of the second flange 35 and the upper end of the base 32. The rotating connection member 36 is rotatably matched with the second flange 35 and the base 32. By arranging the rotating connection member 36 between the bottom of the second flange 35 and the upper end of the base 32, the second flange 35 can be prevented from contacting with the upper end of the base 32 to cause wear, thereby effectively extending the service life of the workpiece fixing device of the rotary felt equipment.

[0064] Preferably, the rotating connection member 36 is a one-way thrust bearing, wherein the race of the bearing is connected to the upper end of the base 32, the shaft ring of the bearing is connected to the bottom of the second flange 35, and a plurality of balls are arranged between the race and the shaft ring. Since the rotating connection member 36 can reduce the resistance when the second flange 35 rotates, the power requirement for the first drive motor is reduced, and the first drive motor with lower power can be used to drive the chassis turntable 10 to rotate.

[0065] In one embodiment, the workpiece fixing device of the rotary felt equipment includes two tooling installation components 20, which are respectively referred to as a first tooling installation component and a second tooling installation component. The two tooling installation components 20 are arranged in parallel, and the two tooling installation components 20 respectively drive the corresponding heat preservation tube clamping rotating component 130 to move in opposite directions. Figure 8 As shown, the first tooling installation component is arranged on the left side of the upper part of the chassis turntable 10, and the second tooling installation component is arranged on the right side of the upper part of the chassis turntable 10. The first tooling installation component and the second tooling installation component can drive the two heat preservation tube clamping rotating components 130 to move in opposite directions along the first direction without interfering with each other. The first tooling installation component and the second tooling installation component are arranged in parallel, which improves the compactness of the workpiece fixing device of the rotary felt equipment and reduces the volume of the workpiece fixing device of the rotary felt equipment.

[0066] In one embodiment, the tooling installation component 20 includes a second drive assembly 21 and a tooling installation seat 22, and the second drive assembly 21 is arranged on the upper part of the base turntable 10. The second drive assembly 21 includes a second drive motor, a second reducer and a screw mechanism, the rotating shaft of the second drive motor is connected to the input shaft of the second reducer, the output shaft of the second reducer is connected to the screw 24 of the screw mechanism, and two slide rails 25 of the screw mechanism are arranged at intervals on the upper surface of the base turntable 10, and the two slide rails 25 are arranged on both sides of the screw 24, and the screw 24 and the slide rails 25 are arranged in parallel.

[0067] The tooling mounting seat 22 is connected to the second driving assembly 21. Specifically, the tooling mounting seat 22 is a hollow frame. At least two sliders are provided at the bottom of the tooling mounting seat 22. The sliders are connected to the bottom of the tooling mounting seat 22 by screws. The sliders are provided with slide grooves. The sliders are slidably clamped on the slide rails 25 through the slide grooves, so that the tooling mounting seat 22 can slide along the length direction of the slide rails 25. The tooling mounting seat 22 is connected to the screw nut of the screw mechanism. Preferably, the tooling mounting seat 22 is connected to the screw nut through a connecting rod.

[0068] The second driving assembly 21 is used to drive the tooling mounting seat 22 to move linearly along the first direction, so as to drive the thermal insulation tube clamping rotating component 130 to move. When the second driving motor drives the second reducer to rotate, the second reducer drives the screw rod 24 to rotate, the screw rod 24 drives the screw nut to move along the length direction of the screw rod 24, and the screw nut drives the tooling mounting seat 22 to move along the length direction of the screw rod 24, thereby changing the position of the thermal insulation tube clamping rotating component.

[0069] In one embodiment, a connecting plate 23 is provided at one end of the tooling mounting seat 22 away from the second drive assembly 21. The connecting plate 23 is vertically arranged, and the connecting plate 23 is welded to the end of the tooling mounting seat 22 away from the second drive assembly 21. Of course, the connecting plate 23 can also be integrally formed with the tooling mounting seat 22 or bolted. The connecting plate 23 is connected to the insulation tube clamping rotating component. Specifically, the connecting plate 23 is connected to the insulation tube clamping rotating component 130 by bolts. A through hole is provided on the connecting plate 23, and the through hole is used for the rotating shaft of the insulation tube clamping rotating component 130 to pass through. It should be noted here that the end of the tooling mounting seat 22 away from the second drive assembly 21 refers to the end of the tooling mounting seat 22 away from the second drive motor.

[0070] Working principle of workpiece fixing device of rotary felt equipment:

[0071] When the work starts, the insulation tube clamping rotating component 130 on the first tooling installation component is at the felt rolling station, and the insulation tube clamping rotating component 130 on the second tooling installation component is at the baling station. When the insulation tube at the baling station completes baling, the insulation tube clamping rotating component 130 releases the insulation tube and puts down the baled insulation tube. The first drive motor drives the rotating shaft to rotate through the first reducer, and the rotating shaft drives the chassis turntable 10 to rotate 180°, rotating the insulation tube that has been rolled at the felt rolling station to the baling station. During the baling process, when the position of the insulation tube needs to be moved, the second drive motor drives the second reducer to rotate, the second reducer drives the screw rod 24 to rotate, the screw rod 24 drives the screw nut to move along the length direction of the screw rod 24, and the screw nut drives the tooling installation seat 22 to move along the length direction of the screw rod 24, thereby changing the position of the insulation tube at the baling station.

[0072] Exemplarily, when the work starts, the insulation tube clamping rotating component 130 on the first tooling installation component is at the felt rolling station, and the insulation tube clamping rotating component 130 on the second tooling installation component is at the baling station. When the insulation tube at the baling station completes baling, the second tooling installation component drives the insulation tube clamping rotating component 130 at the baling station to move forward until the insulation tube clamping rotating component 130 is placed in the accommodating chamber 303 of the conveying device 300. At this time, the insulation tube clamping rotating component 130 releases the insulation tube 170, and the baled insulation tube 170 is placed in the accommodating chamber 303 of the conveying device 300. When the insulation tube clamping rotating component 130 at the felt rolling station does not clamp the insulation tube, the first tooling installation component drives the insulation tube clamping rotating component 130 at the felt rolling station to move backward along the first direction until the insulation tube clamping rotating component 130 can clamp the insulation tube on the conveying device 300.

[0073] Combine the following Figures 1 to 6 The heat preservation tube clamping and rotating device of the embodiment of the utility model is described in detail.

[0074] In one embodiment, Figure 1 and Figure 2 As shown, the heat preservation tube clamping and rotating device 100 includes two heat preservation tube clamping and rotating components 130, and the two heat preservation tube clamping and rotating components 130 are symmetrically arranged on the tooling installation component 20. When the tooling rotation component drives the chassis turntable 10 and then drives the tooling installation component 20 to rotate 180 degrees, the heat preservation tube clamping and rotating components 130 clamped by the heat preservation tube 170 at the rolling station rotate to the baling station, and the heat preservation tube clamping and rotating components 130 that have completed baling rotate from the baling station to the felt rolling station.

[0075] In one embodiment, the insulation tube clamping and rotating device 100 further includes at least two insulation tube rotating parts 110; the insulation tube rotating parts 110 are mounted on the tooling mounting parts 20 and correspond one to one with the insulation tube clamping and rotating parts 130. The insulation tube clamping and rotating parts 130 are connected to the corresponding tooling mounting parts 20 through the corresponding insulation tube rotating parts 110; the insulation tube rotating parts 110 are used to drive the insulation tube clamping and rotating parts 130 to drive the insulation tube 170 to rotate. By setting the insulation tube rotating parts 110, the insulation tube 170 clamped by the insulation tube clamping and rotating parts 130 can be driven to rotate, so as to realize the felt rolling and bundling of the insulation tube 170.

[0076] like Figures 3 to 5 As shown, in one embodiment, the heat preservation tube clamping rotating component 130 includes a first linear drive component 131, a connecting component 132, at least two connecting rod components 133 and at least two chuck components 134, wherein the chuck component 134 is arranged at the edge of one side of the heat preservation tube rotating component 110 and slides with the heat preservation tube rotating component 110 in the radial direction; one end of the connecting rod component 133 is hinged to the corresponding chuck component 134, the other end of the connecting rod component 133 is connected to one end of the connecting component 132, and the other end of the connecting component 132 is connected to the first linear drive component 131. The assembly 131 is connected, and the first linear drive assembly 131 is used to drive the connecting assembly 132 to move axially to drive the clamp assembly 134 to switch between the first position and the second position; in the first position, the clamp assembly 134 is in contact with the inner wall of the insulation tube 170, and the clamp assembly 134 clamps the insulation tube 170; in the second position, the clamp assembly 134 is separated from the inner wall of the insulation tube 170, and the clamp assembly 134 releases the clamping of the insulation tube 170; the insulation tube rotating component 110 is used to drive the connecting rod assembly 133 and the clamp assembly 134 to rotate.

[0077] It should be noted that in the present invention, the radial direction refers to the direction along the radius of the turntable 111 , and the axial direction refers to the length direction along the central axis of the turntable 111 .

[0078] The insulation tube clamping and rotating device 100 provided by the utility model drives the connecting component 132 to move axially through the first linear drive component 131, so as to drive the chuck component 134 to switch between the first position and the second position; in the first position, the chuck component 134 is in contact with the inner wall of the insulation tube 170, and the chuck component 134 clamps the insulation tube 170; the connecting rod component 133 and the chuck component 134 are driven to rotate through the insulation tube rotating component 110, thereby driving the insulation tube 170 to automatically wrap the felt around the outer circumferential surface of the insulation tube 170 during the rotation process, without the need for manual winding, which effectively reduces the work intensity and improves the work efficiency.

[0079] like Figure 3As shown, in one embodiment, the heat preservation tube clamping rotating component 130 includes three connecting rod assemblies 133, and the angles between any two connecting rod assemblies 133 are equal. The three connecting rod assemblies 133 cooperate with the clamp assembly 134 to clamp the heat preservation tube 170, which has the advantages of high centering accuracy and good stability.

[0080] like Figure 3 and Figure 5 As shown, in one embodiment, the heat preservation cylinder rotating component 110 includes a turntable 111, a rotation drive assembly 112 and a transmission assembly 113. The turntable 111 is a circular plate-like structure. In order to reduce the weight of the turntable 111, the turntable 111 is provided with a hollow portion. The turntable 111 can be rotatably mounted on the outer periphery of the connecting assembly 132.

[0081] The chuck assembly 134 is arranged at the edge of one side of the rotating disk 111. The number of the chuck assembly 134 is the same as the number of the connecting rod assembly 133. In this embodiment, three chuck assemblies 134 are arranged, and the three chuck assemblies 134 are arranged equidistantly along the circumference of the disk. Of course, the number of the chuck assemblies 134 is not limited thereto, and is specifically determined according to the number of the connecting rod assemblies 133. Each chuck assembly 134 is slidably matched with the rotating disk 111 in the radial direction, so that the chuck assembly 134 slides between the first position and the second position.

[0082] The rotating drive assembly 112 is disposed on the rotating bracket, and the rotating drive assembly 112 is located on the other side of the rotating disk 111. The rotating drive assembly 112 drives the rotating disk 111 to rotate.

The first bearing 115 can reduce the resistance encountered by the rotating disk 111 during rotation. In this embodiment, the first bearing 115 is an angular contact ball bearing. Of course, the specific type of the first bearing 115 is not limited thereto, and other types of bearings can also be used.

During the rotation of the turntable 111, the connecting rod assembly 133 and the felt clamping part 150 rotate along with the turntable 111. In order to ensure that the wires and air circuits for controlling the felt clamping part 150 can be led out, a conductive slip ring 118 is provided. The center of the conductive slip ring 118 can pass through one air circuit, and 24 wires can pass around it, which can meet the wire requirements of the driving cylinder, servo motor and sensor of the felt clamping part 150.

[0088] like Figure 3 and Figure 5 As shown, in one embodiment, the first linear drive component 131 is used to drive the lifting shaft 136 to move axially, and the first linear drive component 131 is a cylinder, the cylinder body of the cylinder is connected to the rotating bracket, and the telescopic rod of the cylinder is connected to the other end of the connecting component 132. Of course, the specific type of the first linear drive component 131 is not limited thereto, and it can also be an oil cylinder, an electric push rod or other linear drive components 131.

[0089] like Figure 5 As shown, in one embodiment, the connecting assembly 132 includes a bushing 135 and a lifting shaft 136. The bushing 135 is a hollow tubular structure. The bushing 135 is coaxially arranged with the first bearing 115. The bushing 135 is inserted into the first bearing 115, that is, the inner ring of the first bearing 115 is sleeved on the outer circumferential surface of the bushing 135. One end of the bushing 135 is connected to the first linear drive assembly 131 and the rotary drive assembly 112, and the other end of the bushing 135 extends to one side of the turntable 111. Specifically, one end of the bushing 135 is connected to the connecting plate 23 of the tooling installation component 20. During the rotation of the turntable 111, the bushing 135 does not rotate, and the bearing seat 114 rotates relative to the bushing 135 through the first bearing 115.

[0090] The lifting shaft 136 is a hollow tubular structure. Of course, the lifting shaft 136 can also be a solid rod-shaped structure. The lifting shaft 136 is inserted into the bushing 135, and the lifting shaft 136 is coaxially arranged with the bushing 135. One end of the lifting shaft 136 is rotatably matched with the other end of the connecting rod assembly 133, and the other end of the lifting shaft 136 is connected to the first linear drive assembly 131; specifically, the other end of the lifting shaft 136 is connected to the telescopic rod of the cylinder through a screw. The cylinder can control multiple connecting rod assemblies 133 to move at the same time through the lifting shaft 136, which reduces the number of cylinders, simplifies the structure and reduces the production cost.

[0091] like Figure 3 and Figure 5 As shown, in one embodiment, the heat preservation tube clamping rotating component 130 further includes a connecting ring 137, which is sleeved on the outer periphery of one end of the lifting shaft 136, and the connecting ring 137 is rotatably matched with one end of the lifting shaft 136 through a second bearing. Specifically, the inner ring of the second bearing is sleeved on one end of the lifting shaft 136, and the outer ring of the second bearing is sleeved inside the connecting ring 137. By arranging the second bearing between the connecting ring 137 and the lifting shaft 136, the resistance during the rotation of the turntable 111 is further reduced. The connecting ring 137 is used to connect the connecting rod assembly 133 and the lifting shaft 136, and the other end of the connecting rod assembly 133 is connected to the connecting ring 137. The connection ring 137 can facilitate the connection between the connecting rod assembly 133 and the lifting shaft 136.

[0092] like Figure 3 and Figure 5As shown, in one embodiment, the connecting rod assembly 133 includes a fixed connecting rod 138 and a movable connecting rod 139, one end of the fixed connecting rod 138 is connected to the connecting ring 137, specifically, one end of the fixed connecting rod 138 is provided with a connecting portion, and the connecting portion is connected to the outer peripheral surface of the connecting ring 137 by screws. Of course, the connection method of the fixed connecting rod 138 and the connecting ring 137 is not limited thereto, and can also be connected by welding or integral molding. One end of the movable connecting rod 139 is hinged to the other end of the fixed connecting rod 138, and the other end of the movable connecting rod 139 is hinged to the corresponding clamp assembly 134.

[0093] like Figure 3 and Figure 5 As shown, in one embodiment, the clamping head assembly 134 includes a slider 140 and a clamping head 141. The slider 140 is arranged parallel to the turntable 111 and is in the form of a rectangular parallelepiped. Of course, the specific shape of the slider 140 is not limited thereto and may also be other shapes.

[0094] A guide rail extending in a radial direction is provided on the edge of one side of the turntable 111. The guide rail is connected to the turntable 111 by screws, and the guide rail is provided in the radial direction of the turntable 111. The number of the guide rails is the same as the number of the sliders 140, and the positions of the guide rails correspond to the positions of the sliders 140 one by one. Of course, one slider 140 can also slide with two parallel guide rails. The slider 140 slides with the corresponding guide rails, and one end of the connecting rod assembly 133 is hinged with the corresponding slider 140; specifically, the slider 140 is arranged parallel to the turntable 111, and a slide groove is provided on the side of the slider 140 facing the turntable 111, and the slider 140 can be slidably clamped on the guide rail through the slide groove. A connecting ear is provided on the side of the slider 140 away from the turntable 111, and one end of the connecting rod assembly 133 is hinged with the connecting ear through a pin.

[0095] The clamping head 141 is a block-shaped structure. The clamping head 141 is arranged parallel to the inner wall of the heat preservation tube 170. Preferably, the clamping head 141 is arranged perpendicular to the slider 140. The clamping head 141 is connected to the slider 140. In this embodiment, the clamping head 141 and the slider 140 are connected by screws. Of course, the clamping head 141 and the slider 140 can also be welded or integrally formed. In the first position, the clamping head 141 fits the inner wall of the heat preservation tube 170; at this time, since the thrust direction generated by each clamping head 141 on the inner wall of the heat preservation tube 170 is different, under the action of friction, the heat preservation tube 170 is fixed on the heat preservation tube clamping rotating component 130. In the second position, the clamping head 141 is separated from the inner wall of the heat preservation tube 170 to facilitate the removal of the heat preservation tube 170.

[0096] like Figure 4 and Figure 6As shown, in one embodiment, the heat preservation tube clamping and rotating device further includes a felt clamping component 150, which is disposed on one side of the turntable 111 and is used to clamp the felt to the outer surface of the heat preservation tube 170. By arranging the felt clamping component 150 to clamp the felt to the outer surface of the heat preservation tube 170, the felt rolling can be fully automated, further reducing the labor intensity. In addition, the felt clamping component 150 is integrated on one side of the turntable 111, which effectively improves the compactness of the heat preservation tube and the felt clamping and rotating device, and further reduces the production cost.

[0097] like Figure 6 As shown, in one embodiment, the felt clamping component 150 includes a second linear drive component 151, a first connecting frame 152, a second connecting frame 156, two third linear drive components 153, two felt chucks 154 and a fourth linear drive component. The second linear drive component 151 is arranged on one side of the turntable 111, and one end of the first connecting frame 152 is connected to the second linear drive component 151. The second linear drive component 151 is used to drive the first connecting frame 152 to move radially to change the distance between the felt chuck 154 and the insulation tube 170. One end of the second connecting frame 156 is hinged to the other end of the first connecting frame 152, a third linear drive assembly 153 is arranged on the first connecting frame 152, another third linear drive assembly 153 is arranged on the second connecting frame 156, two felt chucks 154 are arranged symmetrically, one felt chuck 154 is connected to the third linear drive assembly 153 on the first connecting frame 152, and the other felt chuck 154 is connected to the third linear drive assembly 153 on the second connecting frame 156, and the third linear drive assembly 153 drives the two felt chucks 154 to move closer to or away from each other, so that the two felt chucks 154 are stuck at both ends of the heat preservation tube 170. The fourth linear drive assembly is hinged to the second connecting frame 156 and the first connecting frame 152. When the fourth linear drive assembly is extended, the fourth linear drive group drives the second connecting frame 156 away from the central axis of the turntable, so that the two felt chucks 154 are on the same straight line. When the fourth linear drive assembly is shortened, the fourth linear drive group drives the second connecting frame 156 to approach the central axis of the turntable to facilitate the removal of the insulation cylinder 170 after the felt is rolled.

[0098] Furthermore, in order to prevent the turntable 111 from hindering the movement of the felt chuck 154 , a notch is provided at the edge of the turntable 111 , and the notch allows the felt chuck 154 to move to the other side of the turntable 111 .

[0099] like Figure 4 and Figure 6As shown, in one embodiment, the second linear drive assembly 151 includes a servo motor and a screw module, the housing of the servo motor is connected to the turntable 111 by screws, and the rotating shaft of the servo motor is connected to the screw of the screw module. The slide rail of the screw module is connected to the turntable 111 by screws, and the first connecting frame 152 is connected to the sliding block of the slide rail of the screw module by screws.

[0100] In one embodiment, the first connecting frame 152 includes a first connecting plate and a second connecting plate, the first connecting plate is arranged parallel to the rotating disk 111, and the first connecting plate is connected to the sliding block of the screw module slide rail by screws. The second connecting plate is arranged parallel to the inner wall of the heat preservation cylinder 170, the second connecting plate is perpendicular to the first connecting plate, the second connecting plate is welded to the first connecting plate or integrally formed, a third linear drive assembly 153 is arranged on the second connecting plate, and one end of the second connecting plate away from the first connecting plate is hinged to one end of the second connecting frame 156.

[0101] like Figure 4 and Figure 6 As shown, in one embodiment, the third linear drive assembly 153 includes a driving cylinder, two driving cylinders are arranged on the second connecting plate along the width direction of the heat preservation cylinder, the cylinder body of one driving cylinder is connected to the second connecting plate by screws, and the cylinder body of the other driving cylinder is connected to the second connecting frame 156 by screws, and the telescopic rods of the two driving cylinders are connected to the two felt clamps 154 one by one by screws, and the movement directions of the telescopic rods of the two driving cylinders are opposite. Preferably, the driving cylinder is a rodless cylinder, and the use of a rodless cylinder can reduce the volume of the felt clamping component 150.

[0102] Working principle of the thermal insulation tube clamping and rotating device 100:

[0103] Before the felt rolling process begins, the heat preservation tube 170 needs to be fixed. When the cylinder extends, the cylinder drives the lifting shaft 136 to move upward. The lifting shaft 136 drives the three connecting rod assemblies 133 to the recovery arm through the connecting ring 137. The connecting rod assembly 133 drives the corresponding chuck assembly 134 to approach the lifting shaft 136, so that the clamping head 141 is separated from the inner wall of the heat preservation tube 170. When the cylinder retracts, the cylinder drives the lifting shaft 136 to move downward. The lifting shaft 136 drives the three connecting rod assemblies 133 to the outward arm through the connecting ring 137. The connecting rod assembly 133 drives the corresponding chuck assembly 134 to approach the inner wall of the heat preservation tube 170 until the heat preservation tube 170 is completely attached. At this time, the cylinder no longer moves due to resistance. The three clamping heads 141 are attached to the inner wall of the heat preservation tube 170, so that the rotation center of the heat preservation tube and the chuck is coaxial, and the fixing action of the heat preservation tube 170 is completed.

[0104] After the heat preservation tube 170 is fixed, the felt needs to be clamped. In the initial state, the two felt clamps 154 move outwards and are in an open state; when the servo motor drives the first connecting frame 152 to approach the inner wall of the heat preservation tube 170, the servo motor stops rotating. When the felt chuck 154 is no longer pressed against the felt 160, the two driving cylinders drive the first connecting frame 152 to expand outward until it is completely separated from the felt 160.

[0105] When the driving motor rotates, the driving motor drives the reducer to drive the driving gear 116 to rotate, and the driving gear 116 drives the turntable 111 to rotate through the driven gear 117, and the turntable 111 drives the felt clamping component 150 to rotate, winding the felt around the outside of the insulation tube 170 in circles.

[0106] Combine the following Figure 1 , Figure 2 as well as Figures 14 to 16 The conveying device 300 according to the embodiment of the present utility model is described in detail.

[0107] like Figure 1 and Figure 2 As shown, in one embodiment, the single crystal furnace insulation tube felt rolling equipment further includes at least two conveying devices 300; at least one conveying device 300 is used to convey the insulation tube 170 that has not been rolled up to the insulation tube clamping rotating component 130 of the felt rolling station, and at least one conveying device 300 is used to transport the insulation tube 170 of the bundling station to the waiting station along the first direction. By providing at least two conveying devices 300, at least one conveying device 300 is used to convey the insulation tube 170 that has not been rolled up to the insulation tube clamping rotating component 130 of the felt rolling station, and at least one conveying device 300 is used to transport the insulation tube 170 of the bundling station to the waiting station along the first direction, the two conveying devices 300 can work separately, further improving the felt rolling efficiency.

[0108] Exemplarily, two conveying devices 300 are included, and both conveying devices 300 are arranged on the installation platform 200. One of the conveying devices 300 is used to convey the un-felt-wound insulation cylinder 170 to the insulation cylinder clamping rotating component 130 of the felt-rolling station, and the other conveying device 300 is used to transport the insulation cylinder 170 of the baling station along the first direction to the waiting station.

[0109] like Figures 14 to 16 As shown, in some embodiments, the conveying device 300 includes a supporting component 301 and a conveying component 302. The supporting component 301 has a receiving cavity 303, and a first opening 304 is formed on one side of the receiving cavity 303 facing the predetermined position of the heat preservation tube 170. The supporting component 301 is used to abut against the outer side of the heat preservation tube 170 to support the heat preservation tube 170; the opening is used for the heat preservation tube 170 to enter and exit the receiving cavity 303. The conveying component 302 is connected to the supporting component 301, and is used to drive the supporting component 301 to move along the first direction to transport the heat preservation tube 170 to the predetermined position.

[0110] In this embodiment, by providing a support component 301 with a accommodating cavity 303, the position of the insulation tube 170 can be limited, and the insulation tube 170 can be prevented from moving during transportation. By providing a first opening 304 on the side of the accommodating cavity 303 facing the predetermined position, it is convenient for the insulation tube 170 to enter and exit the accommodating cavity 303 along the first direction, thereby improving the convenience of operation. By providing a conveying component 302 connected to the support component 301, the conveying component 302 drives the support component 301 to move the insulation tube 170 along the first direction, and the insulation tube 170 is transported to the predetermined position. Compared with the existing method of transporting the insulation tube 170 using a clamping mechanism, the conveying device of this embodiment is not only simple to operate and avoids pinching the insulation tube, but also can prevent the insulation tube 170 from moving during transportation.

[0111] It should be noted that the first direction is the conveying direction of the heat preservation tube 170. Figures 14 to 16 In the embodiment, the first direction may be a front-to-back direction. The second direction intersects with the first direction, and the second direction may be a left-to-right direction.

[0112] like Fig.14 As shown, in one embodiment, the support component 301 includes a support base 310, a support assembly 320 and a locking assembly 330. The support base 310 is connected to the conveying component 302. The support assembly 320 is located above the support base 310, and the support assembly 320 is connected to the support base 310, and is used to support the heat preservation cylinder 170; the support assembly 320 has a receiving cavity 303; the support assembly 320 can be switched between the first position and the second position to adjust the caliber of the opening. The locking assembly 330 is connected to the support assembly 320, and is used to lock the support assembly 320 in the first position or the second position.

[0113] In this embodiment, by providing a support base 310, the support assembly 320 is connected to the conveying member 302. By providing a support assembly 320 having a receiving cavity 303, and the support assembly 320 can also be switched between a first position and a second position, the caliber of the first opening 304 can be made variable, which is suitable for supporting heat preservation tubes 170 of different diameters, thereby expanding the scope of application. By providing a locking assembly 330, the support assembly 320 can be locked in the first position and the second position to prevent the heat preservation tube 170 from moving in the up and down directions when the heat preservation tube 170 is transported.

[0114] like Fig.15 As shown, further, the support base 310 includes a support bottom plate 311 and a support side plate 312; the lower end of the support bottom plate 311 is connected to the conveying component 302, and the upper end of the support bottom plate 311 is connected to the support assembly 320; the support side plate 312 is located above the support bottom plate 311, and is connected to one end of the support bottom plate 311 away from the predetermined position, and both ends of the support side plate 312 on the side away from the support bottom plate 311 are connected to the support assembly 320.

[0115] Specifically, the supporting side plate 312 is vertically mounted on one end of the upper side surface of the supporting bottom plate 311 away from the predetermined position, and the supporting side plate 312 and the supporting bottom plate 311 form an L-shaped structure.

[0116] It should be noted that the conveying device is used to convey the insulation cylinder 170 to a predetermined position, which may be a felt rolling station or a waiting station; the waiting station may be used to store the insulation cylinder 170 wrapped with felt and bundled. Specifically, the conveying device 300 is used to convey the empty insulation cylinder 170 to the felt rolling station. The conveying device 300 conveys the insulation cylinder 170 to the felt rolling station. The insulation cylinder clamping rotating component 130 of the felt rolling station clamps the insulation cylinder 170. At this time, the front side of the insulation cylinder 170 abuts against the turntable 111, and the rear side of the insulation cylinder 170 abuts against the supporting side plate 312. The supporting side plate 312 not only limits the insulation cylinder 170, but also continuously presses the insulation cylinder 170 against the turntable 111. In other words, after the heat preservation tube 170 is transported to the position by the transport device 300 , the supporting side plates 312 also have the function of continuous pressing to prevent the heat preservation tube 170 from being deflected when being clamped and fixed by the heat preservation tube clamping rotating component 130 .

[0117] Preferably, an arc groove is provided at the upper end of the supporting side plate 312 to make the whole machine more beautiful.

[0118] Specifically, waist-shaped holes are respectively provided at both ends of the side of the support side plate 312 away from the support bottom plate 311 along the second direction, and the support assembly 320 is provided in the waist-shaped holes and slides with the support side plate 312 along the second direction. By providing the waist-shaped holes, the support assembly 320 is limited, and the stability of the support assembly 320 moving along the second direction is improved.

[0119] like Figure 2 As shown, further, the support base 310 also includes a support base frame 313; the support base frame 313 is arranged below the support base plate 311, the upper end of the support base frame 313 is connected to the lower end surface of the support base plate 311, and the lower end of the support base frame 313 is slidably matched with the support platform 340 of the conveying component 302 along the first direction. By providing the support base frame 313, the support assembly 320 can be applied to conveying components 302 of different structures, thereby expanding the scope of application.

[0120] like Fig.15 and Fig.16 As shown, in one embodiment, the support assembly 320 includes two swing arm structures; along the second direction, the two swing arm structures are respectively arranged at the two ends of the upper side of the support base plate 311; the two swing arm structures and the support side plate 312 and the support base plate 311 form a accommodating cavity 303, and the upper part of the accommodating cavity 303 has a second opening 305, and the second opening 305 is connected to the first opening 304; the swing arm structure can switch between the first position and the second position to adjust the diameter of the first opening 304 and the second opening 305; the second direction intersects with the first direction.

[0121] In this embodiment, the heat preservation tube 170 is supported by two swing arm structures, which simplifies the structure of the support assembly 320. In addition, by providing two swing arm structures, a second opening 305 can be formed at the upper part of the accommodating cavity 303, and a first opening 304 is formed on the side of the accommodating cavity 303 facing the predetermined position, and the first opening 304 is connected with the second opening 305, so that the heat preservation tube 170 can not only fall into the accommodating cavity 303 from the second opening 305, but also fall into the accommodating cavity 303 from the first opening 304, further improving the convenience of operation.

[0122] like Fig.16As shown, further, the swing arm structure includes a first connecting rod 321 and a second connecting rod 322; one end of the first connecting rod 321 is hinged to the support bottom plate 311. The first connecting rod 321 extends upward and rotates with one end of the second connecting rod 322; the other end of the second connecting rod 322 extends along the first direction and slides with the support side plate 312 along the second direction. By setting the first connecting rod 321 and the second connecting rod 322, not only the support of the heat preservation tube 170 is achieved, but also the adjustment of the diameter of the first opening 304 and the second opening 305 can be achieved, so that the support assembly 320 is applicable to heat preservation tubes 170 of different sizes, expanding the scope of application.

[0123] Furthermore, the swing arm structure further includes a first stopper 324, the rear end of the second connecting rod 322 is slidably matched with the supporting side plate 312 along the second direction, and the front end of the second connecting rod 322 passes through the assembly hole of the first connecting rod 321 and is connected to the first stopper 324. The first stopper 324 is provided to limit the front and rear positions of the first connecting rod 321, so as to prevent the first connecting rod 321 from being separated from the second connecting rod 322 during the left and right swinging process.

[0124] Furthermore, the swing arm structure further includes a conveying roller 323; the conveying roller 323 is sleeved on the outer side of the second connecting rod 322, and the conveying roller 323 and the second connecting rod 322 are axially limited and matched; the conveying roller 323 abuts against the heat preservation cylinder 170. By providing the conveying roller 323, the heat preservation cylinder 170 can be supported. Because the conveying roller 323 and the second connecting rod 322 are axially limited and matched, the conveying roller 323 and the second connecting rod 322 can move synchronously in the axial direction.

[0125] Exemplarily, the conveying roller 323 can be rotatably mounted on the second connecting rod 322. The second connecting rod 322 is provided with a bearing 325, and the bearing 325 and the second connecting rod 322 are axially limited. In other words, the bearing 325 and the second connecting rod 322 can move forward and backward synchronously. The conveying roller 323 and the bearing 325 are rotatably matched.

[0126] Specifically, the two ends of the supporting side plate 312 away from the supporting bottom plate 311 are respectively provided with waist-shaped holes along the second direction; the other end of the second connecting rod 322 is inserted into the waist-shaped hole and is threadedly connected to the locking assembly 330. The swing structure can be locked at any position of the waist-shaped hole by the locking assembly 330 threadedly connected to the other end of the second connecting rod 322. After loosening the locking assembly 330, the second connecting rod 322 can be operated to slide in the waist-shaped hole, thereby driving the first connecting rod 321 to swing along the second direction, so as to adjust the proximity of the two swing structures, and then adjust the calibers of the first opening 304 and the second opening 305. When the calibers of the first opening 304 and the second opening 305 reach the target calibers, tighten the locking assembly 330 to lock the second connecting rod 322 in the waist-shaped hole.

[0127] Specifically, the locking assembly 330 may include a hand wheel or a handle.

[0128] like Fig.14 As shown, in one embodiment, the conveying component 302 includes a support platform 340 and a conveying drive assembly 350; the support platform 340 is located below the support component 301 and slides with the support component 301 along the first direction. The conveying drive assembly 350 is installed on the support platform 340, and is used to drive the support component 301 to move along the first direction. Specifically, the support platform 340 can be a rectangular frame structure, and the support component 301 and the frame body of the support platform 340 slide along the first direction. The conveying drive assembly 350 can be a rodless cylinder, which is located in the hollow area of ​​the support platform 340, and the two ends of the rodless cylinder are connected to the frame body of the support platform 340. The driving end of the rodless cylinder is located below the support component 301 and is connected to the support component 301, and is used to drive the support component 301 to move along the first direction.

[0129] like Fig.14 and Fig.16 As shown, further, the support component 301 is slidably matched with the support platform 340 along the first direction through the sliding connection component 360. The movement stability is improved by providing the sliding connection component 360.

[0130] like Fig.16 As shown, specifically, the sliding connection assembly 360 includes a slider 361 and a slide rail 362; one of the slider 361 and the slide rail 362 is disposed on the support component 301, and the other is disposed on the support platform 340. The slider 361 and the slide rail 362 are slidably matched along a first direction.

[0131] Exemplarily, the slide rail 362 is disposed on the support platform 340 along the first direction, and the slider 361 is disposed on the support component 301 .

[0132] The supporting member 301 of the conveying device 300 can convey the empty insulation cylinder 170 to the felt rolling station, where the empty insulation cylinder 170 is clamped and fixed by the insulation cylinder clamping rotating member 130, and then the supporting member 301 of the conveying device 300 returns. The conveying device can also convey the insulation cylinder 170 on the bundling station to the waiting station.

[0133] Combine the following Figure 1 , Figure 2 and Figure 7 The felt supply device 600 according to the embodiment of the utility model is described in detail.

[0134] In one embodiment, the single crystal furnace insulation cylinder felt rolling device further includes a felt supply device 600 and a feeding mechanism 500; the felt supply device 600 is installed at the loading station of the mounting platform 200, and along the second direction, the loading station is located upstream of the felt rolling station, and the second direction intersects with the first direction; the felt supply device 600 is used to supply felt to the insulation cylinder 170 located at the felt rolling station. The loading station is arranged along the second position, which shortens the length of the whole machine and makes the overall structure of the felt rolling device more compact.

[0135] The feeding mechanism 500 includes a feeding pressing component, which is located between the loading station and the felt rolling station and is used to press the felt onto the heat preservation tube 170. The felt can be tightly wound around the heat preservation tube 170 by providing the feeding pressing component.

[0136] like Figure 1 and Figure 7 As shown, in one embodiment, the felt supply device 600 includes a felt supply component 610; the felt supply component 610 includes a felt supply bracket 611, a felt supply shaft 612 and a felt supply stopper 613; the felt supply bracket 611 is installed on the installation platform 200. The felt supply shaft 612 is used to cooperate with the felt roller in rotation, and one end of the felt supply shaft 612 is connected to the felt supply bracket 611. The other end of the felt supply shaft 612 extends along the first direction and is connected to the felt supply stopper 613, and the felt supply stopper 613 is used to prevent the felt roller from falling off from the other end of the felt supply shaft 612. During the rotation of the heat preservation cylinder 170 of the felt rolling station, the felt drives the felt roller to rotate on the felt supply shaft 612, so that the felt roller releases the felt. By providing the felt supply stopper 613 at one end of the felt supply shaft 612 away from the felt supply bracket 611, the felt roller can be prevented from falling off during the rotation.

[0137] like Figure 7 As shown, further, along the first direction, the felt supply shaft 612 is provided with a limited slot, and the felt supply limiter 613 is provided in the limited slot and is tightly connected to the felt supply shaft 612. By providing the limited slot, and the felt supply limiter 613 can adjust the position in the limited slot, the felt rollers of different radii can be rotatably installed on the felt supply shaft 612, thereby expanding the scope of application.

[0138] In one embodiment, the felt supply device 600 further includes a felt conveying component 620 ; the felt conveying component 620 is used to convey the felt roller to the felt supply shaft 612 , thereby achieving full automation and improving efficiency.

[0139] Furthermore, the felt conveying component 620 includes a felt conveying frame 621 and a felt conveying roller 622; the felt conveying frame 621 has a hollow area, the felt conveying roller 622 is installed in the hollow area, and a transmission belt is sleeved on the outer side of the felt conveying roller 622. At least one felt conveying roller 622 is connected to a power source, and the power source drives the felt conveying roller 622 to rotate, and then drives other felt conveying rollers 622 to rotate through the transmission belt, and finally transports the felt roller to the felt supply shaft 612.

[0140] Combine the following Figure 1 , Figure 2 as well as Figures 10 to 13 The feeding mechanism 500 of the embodiment of the utility model is described in detail.

[0141] like Figures 10 to 13 As shown, in one embodiment, the feeding mechanism 500 includes a feeding pressing component, which is used to press the felt onto the insulation cylinder.

[0142] The feeding and pressing component includes a mounting frame 510, a felt clamping assembly 520 and a felt pressing assembly 540; the felt clamping assembly 520 is used to clamp the felt, one end of the felt clamping assembly 520 is hinged to the mounting frame 510, and the other end is hinged to an end of the felt pressing assembly 540 close to the felt clamping assembly 520. The end of the felt pressing assembly 540 away from the felt clamping assembly 520 is used to press the felt to the heat preservation cylinder.

[0143] In this embodiment, the mounting frame 510 can be used to support the felt clamping assembly 520 and the felt pressing assembly 540, and can also provide an installation position for the felt clamping assembly 520. By providing the felt clamping assembly 520, the felt can be clamped to prevent the felt from being excessively loosened during the process of being wound by the insulation tube. Furthermore, by providing the felt pressing assembly 540, the felt output from one end of the felt clamping assembly 520 close to the felt pressing assembly 540 can be pressed onto the insulation tube; the felt clamping assembly 520 and the felt pressing assembly 540 cooperate to allow the felt to be tightly wound around the insulation tube, thus solving the problem that the felt rolling equipment in the prior art cannot tightly wind the insulation felt around the insulation tube.

[0144] Preferably, one end of the felt pressing assembly 540 away from the felt clamping assembly 520 is located at the upper end of the outer side surface of the insulation tube, and the felt pressing assembly 540 presses the felt to the insulation tube by its own gravity.

[0145] It can be understood that the felt is wrapped around the outside of the insulation tube to play a role in heat preservation.

[0146] During the felt rolling process, the insulation cylinder clamped by the insulation cylinder clamping rotating component 130 located at the felt rolling station rotates, so that the felt first passes through the felt clamping assembly 520, then passes through the felt pressing assembly 540, and is finally wound by the insulation cylinder. When the felt passes through the felt clamping assembly 520, the felt is clamped by the felt clamping assembly 520, and the felt clamping assembly 520 can make the felt have a certain tension. When the felt passes through the felt pressing assembly 540, the felt is pressed to the insulation cylinder by the felt pressing assembly 540, ensuring that the felt can be tightly wound around the insulation cylinder.

[0147] like Fig.10 and Fig.11 As shown, in one embodiment, the feeding and pressing component further includes a mounting adjustment member 530; the two ends of the mounting adjustment member 530 are respectively hinged to the mounting frame 510 and the felt clamping assembly 520, and are used to drive the felt clamping assembly 520 to approach or move away from the insulation tube. By setting the mounting adjustment member 530, the distance between the felt clamping assembly 520 and the insulation tube can be adjusted, so that the feeding mechanism can be applied to insulation tubes of different diameters. In addition, the distance between the felt clamping assembly 520 and the insulation tube can also be adjusted according to the different thicknesses of the felt wound on the insulation tube.

[0148] Specifically, the mounting adjustment member 530 is a cylinder, one end of which is hinged to the mounting frame 510, and the other end of which is hinged to the bottom frame 521. When the mounting adjustment member 530 is extended, the felt clamping assembly 520 is close to the heat preservation tube; when the mounting adjustment member 530 is shortened, the felt clamping assembly 520 is away from the heat preservation tube. The felt pressing assembly 540 is connected to one end of the bottom frame 521 away from the mounting frame 510.

[0149] like Fig.10 and Fig.11 As shown, in some embodiments, the felt clamping assembly 520 includes a bottom frame 521, an upper frame 522, and an upper frame adjusting member 523; one end of the bottom frame 521 is hinged to the mounting frame 510 and the mounting adjusting member 530. The upper frame 522 is located above the bottom frame 521, and one end of the upper frame 522 away from the mounting frame 510 is hinged to the other end of the bottom frame 521. One end of the upper frame adjusting member 523 is hinged to the bottom frame 521, and the other end is hinged to one end of the upper frame 522 close to the mounting frame 510, which is used to drive the upper frame 522 to approach or move away from the bottom frame 521 to clamp or release the felt. By providing the bottom frame 521, the upper frame 522, and the upper frame adjusting member 523 used to drive the upper frame 522 to approach or move away from the bottom frame 521, the felt can be clamped or released. Specifically, when the felt needs to be clamped, the upper frame adjusting member 523 drives the upper frame 522 to approach the bottom frame 521. When the felt needs to be loosened, the upper frame adjusting member 523 drives the upper frame 522 away from the bottom frame 521.

[0150] like Fig.10 As shown, further, the bottom frame 521 includes a bottom frame 5211 and at least one bottom roller 5212; the bottom frame 5211 has a bottom hollow area, one end of the bottom frame 5211 is hinged with the mounting frame 510 and the mounting adjustment member 530; the bottom roller 5212 is rotatably arranged in the bottom hollow area, and the bottom roller 5212 is arranged along the width direction of the felt. By arranging the bottom roller 5212, rolling friction can be achieved between the felt and the bottom frame 521, reducing friction resistance and protecting the felt.

[0151] Specifically, the bottom frame 5211 may be a rectangular frame.

[0152] Exemplarily, when the bottom frame 521 includes a plurality of bottom rollers 5212, the plurality of bottom rollers 5212 are arranged at intervals in the bottom hollow area along the length direction of the felt. In other words, the plurality of bottom rollers 5212 are arranged at intervals in the bottom hollow area along the moving direction of the felt.

[0153] Exemplarily, the outer sides of the plurality of bottom rollers 5212 are sleeved on the conveyor belt. At least one of the plurality of bottom rollers 5212 is connected to a power source, which may be a motor. The bottom roller 5212 connected to the power source is named a power roller. The power source drives the power roller to rotate, and the power roller drives the other bottom rollers 5212 to rotate through the conveyor belt, thereby conveying the felt to the outer side of the insulation cylinder.

[0154] It is understandable that when the insulation cylinder starts to roll the felt, the front end of the felt is clamped by the bottom roller 5212 and the upper roller 5222. The power source is started, the power source drives the active roller to rotate, and the rotating roller drives the other bottom rollers 5212 to rotate through the transmission belt, thereby conveying the front end of the felt to the insulation cylinder.

[0155] It should be noted that a plurality means at least two.

[0156] like Fig.10As shown, further, the upper frame 522 includes an upper frame 5221 and at least one upper roller 5222; the upper frame 5221 has an upper hollow area, and one end of the upper frame 5221 away from the mounting frame 510 is hinged to the other end of the bottom frame 5211; one end of the upper frame 522 close to the mounting frame 510 is hinged to the upper frame adjusting member 523. The upper roller 5222 is rotatably arranged in the upper hollow area, and the upper roller 5222 is arranged along the width direction of the felt, and corresponds to the bottom roller 5212 one by one. By setting the rotatable upper roller 5222, rolling friction can be achieved between the felt and the upper frame 522, reducing friction resistance and protecting the felt. By providing the upper roller 5222 corresponding to the bottom roller 5212 one by one, when the upper frame 522 and the bottom frame 521 are close to each other, the upper roller 5222 and the bottom roller 5212 are close to each other, so as to clamp the felt.

[0157] Specifically, the upper frame 5221 may be a rectangular frame.

[0158] Exemplarily, when the upper frame 522 includes a plurality of upper rollers 5222 , the plurality of upper rollers 5222 are arranged at intervals in the upper hollow area along the length direction of the felt.

[0159] Furthermore, the upper frame adjusting member 523 is a cylinder. When the upper frame adjusting member 523 is extended, the end of the upper frame 522 close to the mounting frame 510 is away from the bottom frame 521, so that the felt can be conveniently placed between the upper frame 522 and the bottom frame 521. Specifically, the felt can be conveniently placed between the upper roller 5222 and the bottom roller 5212. After the felt is placed between the upper frame 522 and the bottom frame 521, the upper frame adjusting member 523 is shortened, and the end of the upper frame 522 close to the mounting frame 510 is close to the bottom frame 521, so as to clamp the felt between the upper frame 522 and the bottom frame 521, thereby ensuring that the felt is in a tensioned state when being wound by the insulation tube.

[0160] like Fig.10 As shown, further, a placement groove 5213 is provided on the upper side of the bottom frame 5211, and when the felt is clamped, the upper frame 5221 is located in the placement groove 5213. By providing the placement groove 5213, on the one hand, the thickness of the felt clamping assembly 520 is reduced, and on the other hand, the gap between the upper roller 5222 and the bottom roller 5212 is reduced, ensuring that the upper roller 5222 and the bottom roller 5212 can clamp the felt.

[0161] It should be noted that when the felt is clamped, it will not affect the conveying of the felt. In other words, although the felt is in a clamped state, the insulation tube can still be wound around the felt.

[0162] like Fig.10 and Fig.11 As shown, in a specific embodiment of the present invention, the felt pressing assembly 540 includes a pressing frame 541, a pressing roller 542 and a pressing adjustment member 543; the pressing frame 541 is hinged to one end of the bottom frame 521 away from the mounting frame 510. The pressing roller 542 is arranged along the width direction of the felt, and the pressing roller 542 is rotatably arranged at one end of the pressing frame 541, and is used to press the felt to the heat preservation tube; one end of the pressing adjustment member 543 is hinged to the other end of the pressing frame 541, and the other end of the pressing adjustment member 543 is hinged to the bottom frame 521, and is used to drive the pressing roller 542 to approach or move away from the heat preservation tube through the pressing frame 541. By setting up the pressing frame 541, a mounting position can be provided for the pressing roller 542; by setting up the pressing adjusting member 543 whose two ends are respectively hinged to the pressing frame 541 and the bottom frame 521, the pressing roller 542 can be driven by the pressing frame 541 to approach or move away from the heat preservation tube, so as to press the felt onto the heat preservation tube. Because the pressing frame 541 is hinged to the bottom frame 521, as the number of felt circles around the heat preservation tube increases, the pressing frame 541 can rotate relative to the bottom frame 521 while keeping the felt pressed onto the heat preservation tube, so that the entire feeding mechanism 500 can flip in the direction away from the heat preservation tube.

[0163] Specifically, the pressing adjusting member 543 is a cylinder. When the pressing adjusting member 543 is extended, the pressing roller 542 fits tightly against the heat-insulating tube, ensuring that the felt is tightly wound around the heat-insulating tube.

[0164] In some embodiments, the feeding and pressing component further includes a specification adjustment component 550; the specification adjustment component 550 is connected to the felt clamping component 520, and along the width direction of the felt, the specification adjustment component 550 is used to adjust the width of the felt through the felt clamping component 520. By providing the specification adjustment component 550, the felt clamping component 520 can be used to clamp felts of different widths, thereby expanding the scope of application.

[0165] like Fig.11 and Fig.13 As shown, further, along the width direction of the felt, the felt clamping assembly 520 forms a limiting portion 524, and the specification adjustment assembly 550 is detachably connected to the limiting portion 524.

[0166] Specifically, the specification adjustment component 550 includes an adjustment plate, which is provided with a clearance groove, in which the upper roller 5222 and the bottom roller 5212 are accommodated. The adjustment plate can move along the width direction of the felt to adjust the width of the felt clamping component 520 for the felt to pass through.

[0167] like Fig.11 and Fig.13As shown, the upper frame 522 further includes a connecting rod 5223, which is installed in the upper hollow area, and the two ends of the connecting rod 5223 are respectively connected to the two side frames of the upper frame 5221; the connecting rod 5223 is provided with a plurality of limiting grooves, which are limiting portions 524, and the plurality of limiting grooves are arranged along the width direction of the felt. The adjustment plate is provided with a through hole, and the connecting rod 5223 is arranged in the through hole. The adjustment plate is clamped with the limiting groove.

[0168] like Fig.10 and Fig.11 As shown, in a specific embodiment of the utility model, the feeding mechanism 500 further includes a felt cutting component 560; the felt cutting component 560 is disposed at the upper portion of one end of the felt clamping assembly 520 away from the mounting frame 510, and the felt cutting component 560 is located between the felt pressing assembly 540 and the felt clamping assembly 520, and is used to cut the felt along the width direction of the felt. By arranging the felt cutting component 560 at the upper portion of one end of the felt clamping assembly 520 away from the mounting frame 510, the structure of the feeding mechanism can be made more compact. The felt clamping assembly 520 can provide support for the felt cutting component 560, avoiding the need to set a support structure solely for supporting the felt cutting component 560, thereby simplifying the structure of the feeding mechanism and reducing the cost.

[0169] like Fig.11 and Fig.12 As shown, further, the felt cutting component 560 includes a cutting linear drive assembly 561 and a cutting knife 562; the cutting linear drive assembly 561 is arranged at the upper part of one end of the bottom frame 521 away from the mounting frame 510, the cutting linear drive assembly 561 is located between the clamping roller 542 and the upper frame 522, the cutting knife 562 is connected to the cutting linear drive assembly 561, and the cutting linear drive assembly 561 is used to drive the cutting knife 562 to move along the width direction of the felt to cut the felt.

[0170] Specifically, the cutting linear drive assembly 561 is a magnetic rodless cylinder, the two ends of the cylinder barrel of the magnetic rodless cylinder are connected to one end of the bottom frame 521 away from the mounting frame 510, the cylinder barrel is arranged along the width direction of the felt, and the cutting knife 562 is connected to the sleeve of the magnetic rodless cylinder by a screw. When the felt on the insulation cylinder is wound a certain number of times, the magnetic rodless cylinder drives the cutting knife 562 to move along the width direction of the felt, and the cutting knife 562 cuts the felt.

[0171] like Figure 1 and Figure 2As shown, in one embodiment, the single crystal furnace insulation cylinder felt rolling device further includes a bundling device 400, which is disposed at the bundling station and is used to bundle the insulation cylinder 170 that has been finished with the felt rolling. The bundling device 400 and the insulation cylinder clamping and rotating device 100 are on the same straight line, thereby forming a linear arrangement of the single crystal furnace insulation cylinder felt rolling device.

[0172] In one embodiment, a steel belt reel placement rack is also provided on the installation platform 200 , and the steel belt reel placement rack is used to place the steel belt reels, and the bundling device 400 uses the steel belt reels to bundle the heat preservation tube 170 .

[0173] 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 it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
