[0033] In the present disclosure, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "first", "second", "middle end" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are relational words determined only for the convenience of describing the structural relationships of the various parts or elements of the present disclosure, and do not specifically refer to any part or element in the present disclosure and should not be understood as limitations on the present disclosure.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of the present invention.

[0035] like Figure 1 to Figure 5As shown, the present invention provides an embodiment of a heat-shrinkable insulating tape heating and winding device, comprising a housing 1, a reeling mechanism 2 is arranged in the housing 1, the reeling mechanism 2 is rotatably connected to the housing 1, the reeling mechanism 2 is used to store the insulating tape, a roller 3, a first heating roller 4 and a second heating roller 5 are arranged on the upper side of the reeling mechanism 2, the roller 3, the first heating roller 4 and the second heating roller 5 are arranged in parallel and extend to the outlet side of the housing 1, a heating mechanism 6 is arranged in the housing 1, a gap 7 is left between the heating mechanism 6 and the outer circle of the roller 3, the first heating roller 4 and the second heating roller 5, the insulating tape passes through the gap 7 and extends to the outside of the housing 1, and a power module 8 is arranged at the lower end of the housing 1, the power module 8 is electrically connected to the first heating roller 4, the second heating roller 5 and the heating mechanism 6. The device of the present invention is provided with a reeling mechanism 2, which is rotatably connected to the housing to realize the orderly storage and automatic reeling of the insulating tape, thereby greatly improving the production efficiency. In the prior art, the storage and reeling of the insulating tape often require manual operation, which is not only inefficient, but also easy to cause material waste. When in use, the heat shrinkable insulating tape is placed on the unwinding mechanism 2, and the insulating tape and the unwinding mechanism 2 are fixedly connected together by means of a fixed block, and the tap of the insulating tape is passed through the gap 7 and extended to the outside of the shell 1. When the tap is pulled, the unwinding mechanism 2 drives the insulating tape to rotate to release more insulating tape. When the insulating tape passes through the heating mechanism 6 and the first heating roller 4 and the second heating roller 5, the heat shrinkable insulating tape is quickly heated to the working point, and the insulating tape is wound around the line connector. In the embodiment of the present invention, the power module 8 adopts a rechargeable power supply, and the battery group is used to power the electrical equipment in the device of the present invention. The insulating tape is fixed on the device of the present invention, and the insulating tape can be pulled out. The outlet position of the pulling out has a heating function, which can ensure that the pulled out insulating tape becomes soft and is convenient for winding. The device of the present invention does not have a power plug, so it is convenient to complete the winding work together with the insulating tape. By using the device to ensure the construction process, the working efficiency of the insulating tape winding is improved.

[0036] The power module 8 includes a battery socket 81 and a battery box 82. The battery socket 81 is fixedly connected to the housing 1. The battery box 82 is plug-fitted and connected to the battery socket 81. The battery socket 81 is electrically connected to the housing 1 and the battery box 82, respectively. In the embodiment of the present invention, the battery box 82 is a rechargeable battery box, which is convenient for charging and replenishing the battery box, and can also facilitate the winding of the device of the present invention with the insulating tape, thereby improving construction efficiency and reducing material waste.

[0037] The housing 1 is provided with a temperature controller 9, and a temperature sensor 10 is provided on one side of the heating mechanism 6. The temperature sensor 10 is electrically connected to the temperature controller 9. The temperature sensor 10 is used to detect the temperature of the heating component and transmit the temperature signal to the temperature controller 9. The temperature controller 9 determines the heating output power according to the height of the detected temperature. The temperature sensor 10 is provided in the device of the present invention, which is used to detect the heating temperature of the first heating roller 4, the second heating roller 5 and the heating mechanism 6 respectively, and set the temperature threshold. When the temperature of the heating component exceeds the set temperature threshold, the heating power output is stopped, which not only protects the insulating belt from the influence of high temperature, but also saves energy consumption. The roller 3 is provided with a speed sensor 11, and the speed sensor 11 is electrically connected to the temperature controller 9. The temperature controller 9 is provided with a display screen 91, a button 92 and a control panel 93. In the embodiment of the present invention, the display screen 92 is connected to the control panel 93 and the temperature sensor 10 respectively. The display screen 91 is used to display the real-time temperature of the heating component. The button 92 is connected to the control panel 93 and is used to adjust the temperature. The temperature can be adjusted in real time through the button 93. In the embodiment of the present invention, multiple heating components are provided so that the insulating tape can be heated evenly during the heating process, thereby avoiding problems such as partial warping of the insulating tape due to uneven heating. This not only improves product quality, but also reduces production costs. In the embodiment of the present invention, the rotation speed sensor 11 is used to detect the rotation speed of the roller 3. When the rotation speed of the roller 3 is fast, the withdrawal speed of the insulating tape is fast. When the rotation speed of the roller 3 is slow, the withdrawal speed of the insulating tape is slow. According to the rotation speed of the roller 3, the heating power of the heating component is adjusted in real time, including but not limited to the heating power of the first heating roller 4, the second heating roller 5 and the heating mechanism 6. To ensure that when the insulating tape is withdrawn at a fast speed, the withdrawn insulating tape has been heated and softened, and can be better wound around the line joint, avoiding the waiting time caused by the slow heating speed of the insulating tape, and improving the winding efficiency of the insulating tape.

[0038] like Figure 3 and Figure 4As shown, the unwinding mechanism 2 includes a rotating shaft 21, a tape spring 22 and a reel 23, the reel 23 is fixedly connected to the rotating shaft 21, the rotating shaft 21 is rotatably connected to the shell 1, the two ends of the rotating shaft 21 are connected to the two ends of the shell 1, the shell 1 is used to support the rotation of the rotating shaft 21, the reel 23 is used to place the insulating tape, and a limiting block is provided on the rotating shaft 21, the limiting block can be a bolt, and can also be other similar limiting mechanisms, which are used to fix the insulating tape on the reel 23, when the insulating tape rotates under the action of the pulling force, the reel 23 and the rotor 21 are driven to rotate, a ratchet 24 is provided between the outer side of the reel 23 and the shell 1, and a pawl 25 used in conjunction with the ratchet 24 is provided on the shell 1, and the pawl 25 is used to limit the ratchet 24 to only rotate in one direction, but not in two directions. One end of the tape spring 22 is connected to the rotating shaft 21, and the other end of the tape spring 22 is connected to the housing 1. The tape spring 22 can be a strip spring, a leaf spring or a torsion spring. The function of the tape spring 22 is to drive the rotating shaft 21 to rotate backward. Due to the action of the ratchet 24 and the pawl 25, the rotating shaft 21 cannot rotate automatically. Since the tape spring 22 has a certain stroke influence, when the reel 23 rotates to a certain extent, part of the elastic force of the tape spring 22 needs to be released to meet the need to pull out a longer length of insulating tape.

[0039] A fixing rod 26 is provided at the end of the tape measure spring 22, and a fixing hole 27 is provided on the housing 1. A fixing cap 28 is provided in the fixing hole 27, and the fixing cap 28 is plugged and matched with the fixing rod 26. In the embodiment of the present invention, the fixing cap 28 is hollow in the middle and has earrings at both ends. A groove of the same size as the fixing cap 28 is provided on the housing 1, and is used to plug the fixing cap 28 into the housing 1. Due to the effect of the earrings, the fixing cap 28 cannot rotate relative to the housing 1. A fixing hole 27 for fixing and limiting the fixing rod is provided inside the fixing cap 28, and the fixing hole 27 and the fixing rod 26 are used in cooperation with each other. When the fixing rod 26 is inserted into the fixing hole 27, one end of the tape spring 22 is connected to the rotating shaft 21, and the other end is connected to the housing 1 through the fixing cap 28. When the reel 23 rotates, the tape spring 22 generates elastic compression. When the reel 23 stops rotating, the reel 23 has a tendency to rotate back under the action of the tape spring 22. Due to the action of the ratchet 24 and the pawl 25, the reel 23 cannot rotate back. When the tape spring 22 is compressed to a certain extent, it can be separated from the fixing rod 26 through the fixing cap 28, so that one end fixed on the housing 1 is in a free state, and the elastic force of the tape spring 22 is released. After the release is completed, the fixing cap 28 is fixedly connected to the fixing rod 26 and the housing again, and the tape spring 22 generates a certain elastic force again. The reel 23 on which the insulating tape is placed is set to a one-way rotating structure, so that the insulating tape can be freely drawn out. When the insulating tape does not need to be drawn out, the insulating tape is connected to the winding device to maintain a certain pre-tightening force, so that the insulating tape can be better wound.

[0040] The housing 1 is provided with a cutting mechanism 12 , and the cutting mechanism 12 abuts against the edge of the insulating tape.

[0041] The shearing mechanism 12 includes a T-shaped push rod 121 and a blade 122 . The blade 122 is fixed to the end of the T-shaped push rod 121 . A spring 123 is sleeved on the T-shaped push rod 121 . Two ends of the spring 123 are respectively in contact with the T-shaped push rod 121 and the housing 1 .

[0042] The heating mechanism 6 includes a preheating component 61 and a quick heating component 62 . The preheating component 61 is electrically connected to the power module 8 , and the quick heating component 62 is electrically connected to the rotation speed sensor 11 .

[0043] The material of the preheating component 61 is a copper plate material, and the quick-heating component 62 is a nickel-chromium alloy material or a ceramic heating material or a carbon fiber heating material.

[0044] The present invention also provides an embodiment of a method for heating and winding a heat shrinkable insulation tape, comprising the following steps:

[0045] Step s1, placing the heat shrinkable insulation tape on the reel 23, and passing the tap of the heat shrinkable insulation tape through the housing 1;

[0046] Step s2, insert the fixing rod 26 into the fixing cap 28, rotate the heat shrinkable insulating tape to a certain angle, and generate a certain torque on the tape spring 22, so that the reel 23 has a tendency to rotate;

[0047] Step s3, starting the heating mechanism 6 to preheat the periphery of the heat shrinkable insulating tape through the preheating component 61;

[0048] Step s4, when it is necessary to extract the insulating tape, the heat shrinkable insulating tape is pulled out with force, and the roller 3 rotates under the pulling action of the heat shrinkable insulating tape, and the speed sensor 11 is used to measure the speed of the roller 3. The temperature controller 9 adjusts the heating power of the first heating roller 4, the second heating roller 5 and the heating mechanism 6 in real time according to the speed value of the roller 3. If the speed of the roller 3 is fast, the heating power of the first heating roller 4, the second heating roller 5 and the heating mechanism 6 is large. If the speed of the roller 3 is slow, the heating power of the first heating roller 4, the second heating roller 5 and the heating mechanism 6 is small. If the speed of the roller 3 is zero, the temperature controller 9 controls the output to stop the power output of the first heating roller 4, the second heating roller 5 and the quick heating component 62;

[0049] Step s5, when the insulating tape is pulled out, the reel 23 is driven to rotate, and while the reel 23 rotates, the tape spring 22 is driven to generate a winding force. If the insulating tape stops being pulled out, the reel 23 rotates under the action of the tape spring 22. A ratchet 24 is provided on one side of the reel 23, and a pawl 25 is provided on the housing 1. The pawl 25 is connected with the ratchet 24. Under the action of the ratchet 24 and the pawl 25, the reel 23 can only rotate in one direction and cannot rotate back, which is used to limit the rotation of the reel 23. The reel 23 can only rotate forward under the action of the pulling force of the insulating tape. When the insulating tape is not pulled out, the reel 23 automatically stops.

[0050] Step s6, when the insulating tape is wound, push the T-shaped push rod 121 so that the blade 122 contacts the insulating tape, and the insulating tape is cut by the cutting mechanism 12. After the cutting work is completed, release the T-shaped push rod 121, and the T-shaped push rod 121 automatically returns to the starting position under the action of the spring 123.

[0051] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.

The reel (23) can only rotate in the forward direction under the action of the drawing force of the insulating tape. When the insulating tape is not drawn out, the reel (23) stops automatically. Step s6, when the insulating tape is wound, the T-shaped push rod (121) is pushed so that the blade (122) contacts the insulating tape and the insulating tape is cut by the cutting mechanism (12). After the cutting work is completed, the T-shaped push rod (121) is released and the T-shaped push rod (121) automatically returns to the starting position under the action of the spring (123).
