[0054] In a specific embodiment of the present invention, Figure 1 and Figure 3 As shown, the first driving assembly 103 includes a first support frame driving motor, a first active rotating gear 106 and a first driven rotating gear 107. The first support frame driving motor is arranged at the bottom of the chassis 108, and the first active rotating gear 106 is arranged at the upper part of the chassis 108.

[0055] In one embodiment of the present invention, Figures 1 to 3 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 rotating bracket 101. When the first driving assembly 103 drives the rotating bracket 101 to rotate 180 degrees, the heat preservation tube clamping and rotating components 130 clamped by the heat preservation tube 170 at the loading station rotate to the felt rolling station, and the heat preservation tube clamping and rotating components 130 that have completed the felt rolling rotate from the felt rolling station to the loading station.

[0056] In one embodiment of the present invention, a rotating component 110 is further included. The rotating component 110 is installed on the rotating bracket 101 . The rotating component 110 and the heat preservation tube clamping rotating component 130 are arranged in a one-to-one correspondence.

[0057] 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.

[0058] 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 .

[0059] The insulation tube and felt clamping and rotating device provided by the utility model drives the connecting assembly 132 to move axially through the first linear drive assembly 131, so as to drive the chuck assembly 134 to switch between the first position and the second position; in the first position, the chuck assembly 134 is in contact with the inner wall of the insulation tube 170, and the chuck assembly 134 clamps the insulation tube 170; the connecting rod assembly 133 and the chuck assembly 134 are driven to rotate through the rotating component 110, thereby driving the insulation tube 170 to automatically wrap the felt 160 around the outer circumferential surface of the insulation tube 170 during the rotation, without the need for manual winding, which effectively reduces the work intensity and improves the work efficiency.

[0060] In one embodiment of the present invention, Figures 4 to 6 As shown, 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.

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.

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.

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.

[0077] In one embodiment of the utility model, the heat preservation tube clamping and rotating device further includes a felt clamping component 150, which is arranged on one side of the turntable 111 and is used to clamp the felt 160 to the outer surface of the heat preservation tube 170. By arranging the felt clamping component 150 to clamp the felt 160 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.

The fourth linear drive assembly 157 is hinged to the second connecting frame 156 and the first connecting frame 152. When the fourth linear drive assembly 157 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 157 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.

[0079] 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 .

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.

[0083] Working principle of the insulation tube and felt clamping and rotating device:

[0084] 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.

[0085] 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 first 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 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 first connecting frame 152 to move toward the center axis of the insulation tube 170 again. The felt chuck 154 slowly fits the felt 160. When the felt chuck 154 completely presses 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 first 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 respectively drive the felt chuck 154 to expand outward until it is completely separated from the felt 160.

[0086] 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.

[0090] The second driving assembly 184 is connected to the lower end of the second supporting frame 185. When the second driving assembly 184 drives the second supporting frame 185 to rotate, the second supporting frame 185 drives the rotating frame 182 to rotate. The rotating rotating frame 182 drives the supply tray 181 to rotate, thereby changing the position of the supply tray 181.

[0091] In a specific embodiment of the present utility model, the second drive assembly 184 includes a second support frame drive motor (not shown), a second active rotating gear and a second driven rotating gear.

Since the two roller mounting frames 320 are arranged at an angle, a conveying channel with a V-shaped cross section is formed. Placing the annular heat preservation tube 170 in the V-shaped conveying channel can prevent the heat preservation tube 170 from moving during the conveying process, thereby improving the stability of the heat preservation tube 170 during the conveying process.
