[0035] In some embodiments of the present invention, a limiting device is further included for limiting and guiding the isolation membrane and the fireproof wrapping tape in the width direction.

[0036] In some specific embodiments of the present invention, the limiting device includes a vertical pole 160 connected to the front surface of the frame 100 and a limiting block 170 spaced apart on the vertical pole 160, and the limiting block 170 is provided with a limiting rod 171 for limiting and guiding the isolation membrane and the fireproof wrapping tape in the width direction. Specifically, the limiting block 170 is provided with a sleeve hole 172 for the vertical pole 160 to pass through, and the limiting block 170 is threadedly connected with a tightening nut 173 to tighten the vertical pole 160 to fix the limiting block 170 on the vertical pole 160, and the sleeve hole 172 can move along the vertical pole 160 to adjust the position of the limiting block 170, and can be adjusted according to actual conditions. The limiting rod 171 passes through the limiting block 170 and protrudes from the limiting block 170 to limit and guide the isolation membrane and the fireproof wrapping tape. Refer to Figure 2 The limiting device is close to the composite roller 120. Since the isolation film and the fireproof wrapping tape will be composited on the composite roller 120, it is arranged near the composite roller 120. It can facilitate the limiting and guiding of the isolation film and the fireproof wrapping tape, and can also well ensure that the isolation film and the fireproof wrapping tape are aligned at the composite roller 120.

[0037] The winding device includes a sleeve 200, an arc hoop 400, a telescopic column 500, a driving motor 600 and a telescopic driving mechanism 700. The sleeve 200 is axially fixed to the front surface of the frame 100 and can rotate along its own axis; a plurality of arc hoops 400 are provided, and are arranged at intervals around the axis of the sleeve 200, and the arc hoop 400 is hinged to the end of the sleeve 200 away from the frame 100; the telescopic column 500 is inserted into the inner side of the arc hoop 400 and the front end extends forward to push the arc hoop 400 to open, and the arc hoop 400 can be driven to rotate when the telescopic column 500 rotates; the driving motor 600 is connected to the telescopic column 500 to drive it to rotate; the telescopic driving mechanism 700 is used to drive the telescopic column 500 to telescopic movement. The driving motor 600 and the telescopic driving mechanism 700 are both installed on the back of the frame 100. The telescopic driving mechanism 700 can be a driving mechanism with telescopic function such as a cylinder and a telescopic motor.

[0038] The drive motor drives the sleeve and the circular hoop to rotate and drive the paper tube to rotate to achieve winding; the telescopic column extends forward to drive the circular hoop to open to achieve clamping of the paper tube, and the telescopic column contracts inward to loosen the circular hoop, making it easy to remove the paper tube. It is convenient to put the paper tube into the circular hoop and remove it, reducing the resistance of putting in and taking out the paper tube, and facilitating operation. Of course, the winding device can be set in multiple groups to switch between multiple workstations to improve efficiency. For example, when another winding device is rotating and winding, the paper tube can be manually set on the winding device of another group to reduce time waste.

[0039] Specifically, the front end of the sleeve 200 is provided with a plurality of hinge seats 230 corresponding to the arc hoop 400, and the rear end of the arc hoop 400 is provided with a hinge part 440 hinged to the hinge seat 230. The hinge part 440 is embedded in the hinge seat 230 and is hinged through a hinge shaft.

[0040] In some embodiments of the present invention, the outer peripheral wall of the telescopic column 500 is provided with an insert block 520 embedded in the gap of the arc hoop 400, and the insert block 520 is embedded in the gap 430 of the arc hoop 400, so that the rotation of the telescopic column 500 drives the arc hoop 400 to rotate. The front end of the insert block 520 is pointed, so that when the telescopic column 500 contracts, the arc hoop 400 can be retracted inward to stop clamping the paper tube.

[0041] In some embodiments of the present invention, the rear end of the telescopic column 500 is provided with a socket 530 extending along its axis, and the driving motor 600 has an output shaft 610 extending into the socket 530, the output shaft 610 matches the socket 530, and the output shaft 610 can drive the telescopic column 500 to rotate and slide along the socket 530. Specifically, the cross-sections of the output shaft 610 and the socket 530 are regular hexagons, so as to achieve torque transmission.

[0042] In some embodiments of the present invention, a raised convex ring 540 is provided on the rear peripheral wall of the telescopic column 500, and the telescopic drive mechanism 700 has a telescopic end 710 that can be telescoped. The telescopic end 710 is provided with two spaced apart shifting blocks 720, and the convex ring 540 partially extends between the two shifting blocks 720. The shifting blocks 720 are extended and retracted to drive the convex ring 540 and the telescopic column 500 to extend and retract, and the telescopic end 710 does not need to rotate together with the telescopic column 500. Of course, if Figure 5 As shown, a cavity is provided in the frame 100 for the telescopic drive mechanism 700 and the drive motor 600 to cooperate with the rear end of the telescopic column 500, and a through hole is provided on the front surface of the frame for the rear end of the telescopic column 500 to be inserted into the cavity.

[0043] In some embodiments of the present invention, a first thrust ball bearing 730 is installed between the protruding ring 540 and the rear shifting block 720 to reduce rotational friction. The first thrust ball bearing 730 is sleeved on the rear end of the telescopic column 500.

[0044] In some embodiments of the present invention, grooves 410 are provided on the outer walls of all arc hoops 400, and the grooves 410 on all arc hoops 400 are aligned. An elastic hoop 420 is embedded in the aligned grooves 410 to apply elastic force to close all arc hoops 400. The elastic hoop 420 is preferably made of elastic rubber material, so as to realize automatic closing and resetting of the arc hoop 400 and automatically loosen the paper tube on the arc hoop 400.

[0045] In some embodiments of the present invention, the winding device also includes a pressure cover 300, which is connected to the front surface of the frame 100 and covers the sleeve 200 to achieve axial positioning of the sleeve 200. A through hole 310 is provided in the center of the pressure cover 300 for the front end of the sleeve 200 to pass through.

[0046] In some specific embodiments of the present invention, the gland 300 is provided with a raised annular protrusion 320 on the side facing the frame 100, and the annular protrusion 320 has an inner hole 330 at the center. The inner hole 330 is coaxial with the through hole 310 and has a diameter larger than the through hole 310. The rear end peripheral wall of the sleeve 200 is provided with a limiting convex circle 210 protruding outward, and the limiting convex circle 210 is placed in the inner hole 330 and has a diameter larger than the through hole 310, thereby realizing axial fixation of the sleeve 200 by the gland 300.

[0047] In some embodiments of the present invention, a second thrust ball bearing 220 is installed between the front side of the limiting convex circle 210 and the bottom wall of the inner hole 330 to reduce friction resistance.

[0048] In some embodiments of the present invention, the inner wall of the arc hoop 400 is a conical surface, and a cone 510 is provided at the front end of the telescopic column 500. The telescopic column 500 can be extended and retracted to drive the arc hoop 400 to open or close through the cooperation between the cone 510 and the arc hoop 400.

[0049] In some embodiments of the present invention, in order to stretch the coiled material, a transition roller 150 is provided between the composite roller 120 and the winding device, and a guide roller 140 is provided on the side of the composite roller 120 away from the winding device, and a tensioning roller 130 is provided above the guide roller 140, and the guide roller 140 and the tensioning roller 130 are provided for winding the fire-resistant wrapping tape.

[0050] In some embodiments of the present invention, the tensioning frame includes a stand 810 , a tensioning roller 820 , a driving mechanism 830 and a rotation speed sensor 840 .

[0051] The tensioning roller 820 is rotatably mounted on the upper part of the stand 810, and is used to overlap the fireproof wrapping tape to pull up the fireproof wrapping tape; the driving mechanism 830 is connected to the tensioning roller 820 to drive it to rotate, and the driving mechanism 830 is mounted on the stand 810, and its output shaft is connected to the tensioning roller 820 to transmit torque. The speed sensor 840 is used to detect the speed of the tensioning roller 820.

[0052] The fireproof wrapping tape tensioning frame provided by the present invention stretches up the fireproof wrapping tape 901 through the tensioning roller 820, and the tensioning roller 820 is higher than the conveyor belt 902. In this way, when the fireproof wrapping tape 901 is separated from the conveyor belt 902, the fireproof wrapping tape 901 and the conveyor belt 902 have a larger separation angle, which makes it easy for the fireproof wrapping tape 901 to detach from the conveyor belt 902. The tensioning roller 820 is then driven to rotate by the driving mechanism 830 to give the fireproof wrapping tape 901 a certain pulling force, making it easier to separate from the conveyor belt 902; the speed sensor 840 monitors and detects the speed of the tensioning roller 820 in real time to prevent the fireproof wrapping tape 901 from being torn off due to its excessive speed.

[0053] Reference Figure 6 and Figure 7 In some embodiments of the present invention, the stand 810 includes a base column 811 and a lifting column 812. The lifting column 812 is connected to the base column 811 in a liftable manner. The tensioning roller 820 is installed on the upper part of the lifting column 812. The lifting and lowering adjustment of the lifting column 812 can realize the lifting and lowering adjustment of the tensioning roller 820. The height of the tensioning roller 820 can be adjusted according to actual needs to adjust the tensioning degree of the fire-proof wrapping tape 901.

[0054] In a specific embodiment of the present invention, the bottom column 811 has a socket 814 with an opening at the top and extending vertically. The socket 814 matches the lifting column 812 so that the lifting column 812 can be inserted and lifted and slid. The upper end of the socket 814 is provided with a first connection hole 815. The lifting column 812 is provided with a second connection hole 816 corresponding to and arranged with the first connection hole 815. The second connection holes 816 are arranged in a vertical direction. The first connection hole 815 selects one of the second connection holes 816 to align and install the fastener 813 to achieve height fixation. The first connection hole 815 selects the second connection holes 816 of different heights to align and achieve height adjustment. The height of the lifting column 812 is fixed by the fastener 813. The fastener 813 can be a bolt and a nut adapted to the bolt.

[0055] In some embodiments of the present invention, two limiting rings 850 are further included. The two limiting rings 850 are spaced apart and sleeved on the outer peripheral wall of the tensioning roller 820. The limiting rings 850 are used to limit and guide the fireproof wrapping tape 901 to a certain extent to avoid affecting the subsequent winding.

[0056] In a further embodiment of the present invention, the limiting ring 850 can be slidably adjusted and fixed along the outer peripheral wall of the tensioning roller 820. By slidingly adjusting the positions of the two limiting rings 850 and adjusting the distance between them, it is possible to cope with fire-resistant wrapping tapes 901 of different widths. When the limiting ring 850 is set too narrow, resulting in excessive limiting of the fire-resistant wrapping tape 901, it can be easily adjusted to meet actual production needs.

[0057] Reference Figure 8In a further embodiment of the present invention, the tensioning roller 820 includes a smooth shaft segment 821 and a threaded shaft segment 822 coaxially connected to both ends of the smooth shaft segment 821. The smooth shaft segment 821 has a smooth surface and is used to overlap the fire-proof wrapping tape 901 and drive the fire-proof wrapping tape 901 to move. The outer peripheral wall of the threaded shaft segment 822 is provided with a thread. The two threaded shaft segments 822 are both threadedly connected with an adjusting rotary sleeve 860 adapted thereto. The two adjusting rotary sleeves 860 are respectively connected to two limit rings 850. It can be understood that the adjusting rotary sleeve 860 is connected to a limit ring 850 that is closer to it. By screwing the adjusting rotary sleeve 860, the adjusting rotary sleeve 860 is moved axially, thereby driving the limit ring 850 to move axially to adjust the position, and the threaded connection will not be easily displaced automatically, thereby playing a certain role in fixing the position.

[0058] In some specific embodiments of the present invention, the adjusting sleeve 860 is fixedly connected to the corresponding limiting ring 850 through a screw 861. The limiting ring 850 is provided with a plurality of stepped through holes. The screw 861 passes through the stepped through holes and the screw head is embedded in the stepped through holes. The adjusting sleeve 860 is correspondingly provided with a threaded blind hole. One end of the screw 861 is threadedly connected to the threaded blind hole. A fixing nut 863 threadedly connected to the screw 861 is also provided between the adjusting sleeve 860 and the limiting ring 850. The fixing nut 863 and the screw head of the screw 861 clamp the limiting ring 850.

[0059] In a further embodiment of the present invention, the threaded shaft section 822 is provided with a pre-tightening nut 862 which is in close contact with the adjusting sleeve 860. Figure 8 As shown, the pre-tightening nut 862 is arranged on the outer side of the adjusting sleeve 860. By tightening the pre-tightening nut 862, an axial force is applied to the adjusting sleeve 860 to play a pre-tightening role, thereby preventing the adjusting sleeve 860 from rotating easily and making its position fixed and stable.

[0060] In a further embodiment of the present invention, the threaded shaft segment 822 of the two threaded shaft segments 822 close to the stand 810 is sleeved with a test ring 870 that can rotate synchronously with the tensioning roller 820, the diameter of the test ring 870 is the same as that of the smooth shaft segment 821, and the speed sensor 840 contacts the test ring 870 to detect the speed of the test ring 870. The speed sensor 840 has a rotating shaft, which contacts and is transmission-connected with the test ring 870 to detect the speed of the test ring 870.

[0061] Specifically, the test ring 870 is threadedly connected to the smooth shaft segment 821. The test ring 870 has the same diameter as the smooth shaft segment 821. The rotation speed of the test ring 870 is the same as the rotation speed of the smooth shaft segment 821, and the fire-proof wrapping tape 901 is overlapped on the smooth shaft segment 821. Therefore, by detecting the rotation speed of the test ring 870, the speed at which the tensioning roller 820 drives the fire-proof wrapping tape 901 can be obtained, thereby realizing the monitoring of the fire-proof wrapping tape 901. The speed sensor 840 is usually connected to the controller, and a speed sensor is also set on the conveyor belt 902 to monitor the transmission speed of the conveyor belt and transmit the data to the controller. The controller is connected to the drive mechanism 830 and the drive motor of the conveyor belt 902 to control their speeds, so as to control the speed of the conveyor belt 902 to keep it synchronized with the speed of the tensioning roller 820 to avoid the speed difference causing the fire-proof wrapping tape 901 to tear or adhere to the conveyor belt 902. The connection and control working principle between the controller, the speed sensor and the motor (drive mechanism) belongs to the conventional prior art, and is not an improvement point of the present invention, so it will not be elaborated here.

[0062] In some embodiments of the present invention, the driving mechanism 830 is connected to the tensioning roller 820 through a reduction gear set 880. Specifically, the driving mechanism 830 is a motor, and the output shaft of the motor is connected to the reduction gear set 880 through a torque connection method such as a coupling to transmit torque. The tensioning roller 820 is provided with a connecting shaft 823 connected to the reduction gear set 880, and the connecting shaft 823 is connected to the reduction gear set 880 through a torque connection method such as a coupling to obtain torque.

[0063] In some embodiments of the present invention, the transition frame includes a base 910 , a column 920 , a first distance sensor 930 , a supporting plate 940 , and a second distance sensor 950 .

[0064] There are two columns 920, which are vertically connected to the base 910. The columns are spaced apart to allow the fire-resistant wrapping tape to pass through the gap, and the two columns 920 are connected as a whole through a connecting rod 922 at the top, and a reinforcing rod 923 is provided between the bottom of the column 920 and the base 910; a first distance sensor 930 is installed in the middle of the upper ends of the two columns 920, and is used to measure the distance of the fire-resistant wrapping tape passing from below; a supporting plate 940 is placed on the base 910, and the supporting plate is located between the two columns 920, and is provided with an opening 941 passing through from top to bottom; a second distance sensor 950 is installed directly below the opening 941, and is used to measure the distance of the fire-resistant wrapping tape passing from above.

[0065] The columns guide and limit the fireproof wrapping tape to a certain extent. When the fireproof wrapping tape is not lowered enough, the first distance sensor can measure it to prevent it from being too tight and too high. The second distance sensor measures the fireproof wrapping tape from the opening of the support plate to prevent it from being lowered too low. The support plate can also support the fireproof wrapping tape to a certain extent when it is too low to prevent it from directly contacting the ground. The fireproof wrapping tape can be measured to reach a more appropriate height.

[0066] When the fireproof wrapping tape is not lowered enough and the height is too high, the fireproof wrapping tape is reeled in slowly (the rotation speed of the drive motor 600 slows down) or the fireproof wrapping tape is unwound faster (the transport speed of the conveyor belt 902 and the rotation speed of the drive mechanism 830 speed up). When the fireproof wrapping tape is lowered too low and the height is too low, the fireproof wrapping tape is reeled in faster (the rotation speed of the drive motor 600 speeds up) or the fireproof wrapping tape is unwound slower (the transport speed of the conveyor belt 902 and the rotation speed of the drive mechanism 830 slow down). By testing the distance of the fireproof wrapping tape, feedback is given to the fireproof wrapping tape unwinding mechanism and the fireproof wrapping tape rewinding mechanism to keep the fireproof wrapping tape in good condition. The controller is connected to the second distance sensor and the first distance sensor, and is connected to the drive motor 600, the drive mechanism 83 and other power mechanisms to control their speed. The connection and control working principle between the controller and the sensor and the motor are conventional existing technologies and will not be elaborated here.
