[0046] In one embodiment of the present invention, Figure 2 As shown, the heat preservation tube clamping component 130 includes three connecting rod assemblies 133, and the angles between any two connecting rod assemblies 133 are equal.

[0048] 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.

[0049] The rotary drive assembly 112 is disposed on the other side of the turntable 111, and the rotary drive assembly 112 is used to drive the turntable 111 to rotate. The turntable 111 is driven to rotate by the rotary drive assembly 112, and the speed of the turntable 111 is constant, which can ensure that the felt 160 is evenly wound around the outer circumference of the heat preservation cylinder 170.

[0050] The transmission assembly 113 is disposed on the other side of the turntable 111 and is connected to the rotation drive assembly 112 and the turntable 111. The transmission assembly 113 is used to transmit the power output by the rotation drive assembly 112 to the turntable 111 to drive the turntable 111 to rotate. The specific structural form of the transmission assembly 113 can be a combination of gears, a combination of a gear and a chain, or a combination of a roller and a belt.

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.

[0053] In one embodiment of the present invention, Figure 4 As shown, the transmission assembly 113 includes a driving gear 116 and a driven gear 117. The driving gear 116 is connected to the rotation drive assembly 112, and the driven gear 117 is connected to the bearing seat 114 and meshes with the driving gear 116. Specifically, the driving gear 116 is sleeved on the output shaft of the reducer, and the driven gear 117 is coaxially arranged with the bearing seat 114, and the driven gear 117 and the bearing seat 114 are connected by screws. The driven gear 117 and the driving gear 116 are in the same plane, and the driven gear 117 meshes with the driving gear 116.

[0054] In one embodiment of the present invention, Figure 3 As shown, the rotating part 110 also includes a conductive slip ring 118, the stator end of the conductive slip ring 118 is connected to one end of the lifting shaft 136, and the rotor end of the conductive slip ring 118 is connected to the connecting ring 137.

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 155, servo motor and sensor of the felt clamping part 150.

[0056] In one embodiment of the present invention, Figure 4 As shown, 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.

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.

[0057] The lifting shaft 136 is a hollow tubular structure. Of course, the lifting shaft 136 can also be a solid rod-shaped structure.

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.

[0058] In one embodiment of the present invention, Figure 4 As shown, the heat preservation tube clamping component 130 also 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.

[0059] In one embodiment of the present invention, Figure 2 As shown, 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 to this, 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.

[0060] In one embodiment of the present invention, Figure 2 As shown, 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.

[0061] 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.

[0062] 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, the heat preservation tube 170 is fixed to the heat preservation tube clamping component 130 under the action of friction. 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.

[0063] In one embodiment of the present invention, Figure 2 As shown, the single crystal furnace insulation cylinder and the felt clamping and rotating device further include a felt clamping component 150, which is arranged on one side of the turntable 111. The felt clamping component 150 is used to clamp the felt 160 on the outer surface of the insulation cylinder 170. By arranging the felt clamping component 150 to clamp the felt 160 on the outer surface of the insulation cylinder 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 single crystal furnace insulation cylinder and the felt clamping and rotating device, and further reduces the production cost.

[0064] In one embodiment of the present invention, Figure 2As shown, the felt clamping component 150 includes a second linear drive component 151, a connecting frame 152, a third linear drive component 153 and two felt chucks 154. The second linear drive component 151 is arranged on one side of the rotating disk 111, and the connecting frame 152 is connected to the second linear drive component 151. The second linear drive component 151 is used to drive the connecting frame 152 to move in the radial direction to change the distance between the felt chuck 154 and the heat preservation tube 170. The third linear drive component 153 is arranged on the connecting frame 152, and the two felt chucks 154 are symmetrically arranged. The two felt chucks 154 are both connected to the third linear drive component 153. The third linear drive component 153 drives the two felt chucks 154 to move closer to or away from each other, so that the two felt chucks 154 are clamped at both ends of the heat preservation tube 170.

[0065] 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 .

[0066] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, 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, 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 connecting frame 152 is connected to the sliding block of the slide rail of the screw module by screws.

[0067] In one embodiment of the utility model, the 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, and the third linear drive assembly 153 is arranged on the second connecting plate.

[0068] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the third linear drive assembly 153 includes two driving cylinders 155, which are arranged on the second connecting plate along the width direction of the heat preservation cylinder, the cylinder bodies of the two driving cylinders 155 are connected to the second connecting plate by screws, the telescopic rods of the two driving cylinders 155 are connected to the two felt clamps 154 by screws in a one-to-one correspondence, and the movement directions of the telescopic rods of the two driving cylinders 155 are opposite. Preferably, the driving cylinder 155 is a rodless cylinder, and the use of a rodless cylinder can reduce the volume of the felt clamping component 150.

[0069] Working principle of single crystal furnace insulation tube and felt clamping and rotating device:

[0070] like Figure 4 As shown, the heat preservation tube 170 needs to be fixed before the felt rolling begins. 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 clamp assembly 134 to approach the lifting shaft 136, so that the clamp 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 clamp 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 clamp 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 clamp is coaxial, and the fixing action of the heat preservation tube 170 is completed.

[0071] After the insulation tube 170 is fixed, the felt needs to be clamped. In the initial state, the two felt chucks 154 move outward and are in an open state; when the servo motor drives the connecting frame 152 to approach the inner wall of the insulation tube 170, the servo motor stops rotating. At this time, the two driving cylinders 155 respectively drive the felt chucks 154 to move inward and are in a retracted state. The felt chucks 154 are close to the end faces at both ends of the insulation tube 170. When the felt 160 is fed between the insulation tube 170 and the felt chucks 154, the servo motor drives the connecting frame 152 to move toward the center axis of the insulation tube 170 again. The felt chucks 154 slowly fit the felt 160. When the felt chucks 154 completely press the felt 160, the torque of the servo motor gradually increases. When the set torque is exceeded, the servo motor stops moving. At this time, the felt chuck 154 is able to press the felt 160 and the insulation tube 170 into a whole. When the felt 160 is completely wrapped around the insulation tube 170, the servo motor drives the connecting frame 152 to move away from the central axis of the insulation tube 170. When the felt chuck 154 just no longer presses the felt 160, the two driving cylinders 155 respectively drive the felt chuck 154 to expand outward until it is completely separated from the felt 160.

[0072] 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 160 around the outside of the insulation tube 170 in circles.

[0073] The utility model also provides a felt roll bundling device, which comprises a feeding device, a bundling device, and the single crystal furnace insulation cylinder and the felt clamping and rotating device as described in any one of the above embodiments.
