Description

Technical Field

[0001] The present invention relates to the technical field of flue gas sampling production equipment, and particularly relates to an automatic winding device for electric heating wires of a flue gas sampling pipe. Background Art

[0002] In the flue gas detection method, the sampling pipe is an essential component. The flue gas in the flue duct is introduced into the pretreatment or analyzer through the sampling pipe; when detecting certain types of gases, the sampling pipe needs to be heated to ensure that the gas is not adsorbed or lost. For the sampling pipe that needs to be heated, heating wires generally need to be wound outside the sampling pipe. At present, when producing the sampling pipe, some wind the electric heating wires outside the sampling pipe by manual winding. The manual winding has low working efficiency and uneven winding spacing. Especially in large-scale production, this traditional manual winding method greatly reduces the production efficiency. There are also some that wind the wires automatically through mechanical equipment, but the current winding equipment on the market costs several thousand yuan at every turn. It not only has a high price, but also has a relatively complex structure and cumbersome operation. Summary of the Invention

[0026] like Figures 1-3 As shown, a device for automatically winding an electric heating wire of a flue gas sampling tube, the flue gas sampling tube comprises a large diameter cylinder 1 and a small diameter round rod 2 connected together, the device comprises a supporting mechanism 3, a power operation mechanism 4, an integrated lead mechanism 5 and a displacement supporting mechanism 6;

[0027] The power operating mechanism 4 comprises:

[0028] The first driving source 41, the rotary main shaft 42 driven by the first driving source 41, and the universal chuck 43 connected to the rotary main shaft 42. The universal chuck 43 rotates with the rotary main shaft 42, and the universal chuck 43 holds the flue gas sampling pipe.

[0029] The second driving source 44, the lead screw 45 driven by the second driving source 44. The lead screw 45 is arranged parallel to the flue gas sampling pipe, and a nut is configured on the lead screw 45.

[0030] The first driving source 41 uses a rotary motor, and the second driving source 44 uses a motor with adjustable speed. The speed of the rotary motor is adjustable. In some embodiments, the first driving source and the second driving source can be connected to a control box. A controller is arranged in the control box, and the power supply of the first driving source and the second driving source can be controlled through the controller. In another way, that is, the working conditions and emergency stop conditions of the rotary motor and the motor with adjustable speed can be controlled. The controller is also connected to a first indication display and a second indication display, which are used to display the speed of the rotary motor and other conditions, and to display the speed of the motor with adjustable speed.

[0031] The support mechanism 3 includes a front support frame 31 and a rear support frame 32. The front support frame 31 and the rear support frame 32 are at least used to jointly support the rotary main shaft 42 and the lead screw 45. Both the front support frame and the rear support frame are quick-install and detachable structures, which are convenient for disassembly and assembly.

[0032] The integrated lead wire mechanism 5 includes:

[0033] A sliding seat 51 fixedly connected to the nut, and an integrated lead wire and tape main body 52 arranged on the sliding seat 51. The integrated lead wire and tape main body 52 includes a sliding table adapter plate 521 and a lead wire and tape mounting seat 522 arranged on the sliding table adapter plate 521. An electric heating wire lead wire tension clamping component 523 and a tape feeding component 524 are arranged on the lead wire and tape mounting seat 522. The electric heating wire lead wire tension clamping component 523 is used to clamp and release the electric heating wire, and the tape feeding component 524 is used to release the tape after the electric heating wire is wound around the flue gas sampling pipe, so that the tape is wound and covered outside the electric heating wire.

[0034] During operation, when the universal chuck 43 holds the flue gas sampling pipe and rotates, after the end of the electric heating wire is wound around the large-diameter cylinder of the flue gas sampling pipe, the electric heating wire on the electric heating wire lead wire tension clamping component 523 will be driven by the rotating flue gas sampling pipe, continuously releasing the electric heating wire, and then the tape feeding component 524 releases the tape. The tape is located above the electric heating wire, so that after the electric heating wire is wound, the tape is simultaneously covered.

[0035] In some achievable embodiments, the seat surface of the lead wire and tape mounting seat 522 forms an angle with the axis of the flue gas sampling pipe Among them The winding angle of the heating wire around the flue gas sampling pipe can be adjusted by adjusting the angle between the plate surface and the axis of the flue gas sampling pipe. Specifically, it can be determined according to formula (1) The angle of:

[0036]

[0037] Among them, d2 represents the inner diameter of the heating wire winding, that is, the diameter of the sampling pipe, Ph represents the length of the heating wire, P represents the pitch of a single turn after the heating wire is wound, and n is the number of turns of the heating wire winding.

[0038] In some other embodiments, the heating wire lead tension clamping assembly 523 includes a pressure wheel 5231 and a cable tension damping member 5232 that are spaced apart on the lead and tape mounting seat. The pressure wheel 5231 is used to press the heating wire released from the heating wire pay-off runner. The cable tension damping member is used to clamp the heating wire with tension, so that the heating wire can be stably wound and also prevent the heating wire from breaking free during winding. It should be noted that the tangent position of the wire outlet of the tension wheel 5231 is lower than the large-diameter cylinder and higher than the small-diameter round rod. When switching from the large-diameter cylinder to the small-diameter round rod, the heating wire descends under the drive of the tension. In some embodiments, when the heating wire is at the large-diameter cylinder position of the sampling pipe, the position of the heating wire is above the heating wire width limiting port (about 5 mm) and runs in a tangent state. When the operation switches to the small-diameter round rod, the tangent point becomes lower, and at the same time, the position of the heating wire will drop to below the heating wire width limiting port (about 6 mm) and run in a tangent state.

[0039] The tape pay-off assembly 524 includes a detachable runner support frame 5241 provided on the lead and tape mounting seat, a detachable rotating shaft 5242 provided on the runner support frame 5241, and a detachable tape rotating wheel 5243 connected to the rotating shaft 5242. A tape mounting space is provided inside the tape rotating wheel 5243. A detachable tape pressing cover 5244 and a damping sleeve 5245 are provided outside the tape rotating wheel 5243. After the tape is loaded into the tape rotating wheel 5243, the tape pressing cover 5244 presses the tape, and the damping sleeve 5245 is sleeved on the tape support at the center of the tape rotating wheel. The damping sleeve 5245 increases the friction with the tape through the silica gel provided inside the damping sleeve 5245 to prevent the tape from slipping during winding. At the same time, the detachable structure of the tape pay-off assembly can quickly replace the tape.

[0040] The runner support frame 5241 is also provided with a direction-adjustable and detachable variable phase support 5246. The end of the variable phase support 5246 is also provided with a detachable damping roller 5247. The damping roller 5247 is used to damp and adjust the tension of the tape led out from the tape rotating wheel 5243.

[0041] The displacement support mechanism 6 includes a lead screw slide 61 detachably arranged on the lead screw, and a moving support base 62 arranged on the lead screw slide 61. A support bracket 63 is arranged on one side of the moving support base 62. The support bracket 63 is fixedly sleeved on a support hollow rod 64. One end of the support hollow rod 64 is sleeved on the small-diameter round rod 2 to support the small-diameter round rod 2, and when the slide base 51 touches the lead screw slide 61, it moves with the lead screw slide 61, so that the heating wire is wound around the small-diameter round rod 2 in sequence.

[0042] The displacement support mechanism 6 further includes a transition combing head 65 arranged at the end of the support hollow rod 64. An inclined sliding panel 66 that can be sleeved on the small-diameter round rod 2 is arranged at the end of the transition combing head 65. The outer diameter of the inclined sliding panel 66 is between the large-diameter cylinder 1 and the small-diameter round rod 2. The transition combing head 65 is used to play a role of buffering and transferring when the heating wire is wound from the large-diameter cylinder 1 to the small-diameter round rod 2, so that the heating wire is smoothly transferred from the large-diameter cylinder 1 to the small-diameter round rod 2.

[0043] In addition, after the heating wire is fixed on the sampling tube, the power operation part starts to rotate, and the heating wire starts to output and wind. When the heating wire is at the position of the large-diameter cylinder of the sampling tube, the position of the heating wire is above the upper part (5 mm) of the heating wire width limiting port and runs in a tangential state. When the operation switches to the small-diameter round rod, the tangent point becomes lower, and at the same time, the position of the heating wire will drop to the lower part (6 mm) of the heating wire width limiting port and run in a tangential state.

[0044] The lead wire and tape mounting seat is adjustably mounted on the slide transfer plate and can be used to adjust the feeding angles of the heating wire and the tape.

[0045] The winding device of this embodiment improves the automation and mechanization of winding, greatly improves the winding speed of the heating wire of the flue gas sampling tube, and reduces the cost.

[0046] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
