[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, a device for detecting the bending performance of an electric heating cable comprises a workbench 1, on which two slide rails 2 are arranged, and further comprises: two bending tables 3 are symmetrically arranged on the slide rails 2, a fixing member 6 is arranged inside the bending table 3, a limiting column 7 is slidably connected to the bending table 3, a bending slide groove is opened on the bending table 3, the limiting column 7 is slidably connected in the slide groove, a second sliding plate 9 is fixedly connected to the outer wall of the fixing member 6, the limiting column 7 is slidably connected to the second sliding plate 9, the outer wall of the limiting column 7 is fixedly connected to the first sliding plate 8, the fixing member 6 is slidably connected to the first sliding plate 8, and the first sliding plate 8 is fitted with the second sliding plate 9; and further comprises:

[0033] Driving mechanism 5, two driving mechanisms 5 are respectively arranged at positions corresponding to the fixing members 6 under the bending table 3, and are used to drive the fixing members 6 to rotate;

[0034] A moving mechanism 4, which is arranged between the two slide rails 2, and two driving mechanisms 5 are symmetrically arranged on the moving mechanism 4, respectively, for driving the two bending tables 3 to move away from or approach each other;

[0035] The fixing member 6 includes a baffle 606, and two baffles 606 are symmetrically arranged on the top of the fixing member 6 to assist in fixing the electric heating tape.

[0036] In this embodiment, when the bending performance of the electric heating tape is tested, the staff first manually pulls up the hollow circular plate 604. When the hollow circular plate 604 is pulled upward, the first tension spring 602 is stretched. When the first tension spring 602 is pulled, a downward force is applied to the second tension spring 605, so that the two ends of the second tension spring 605 can move inward. When moving, the baffles 606 at both ends can be driven to flip upward, so that the baffles 606 leave the outer wall of the hollow circular plate 604. At this time, the electric heating tape to be tested is passed through the fixing member 6 and the limit column 7. The first tension spring 605 is wound around the outer wall of the sleeve 601, and then the hollow circular plate 604 is loosened to make the first tension spring 602 retract to drive the sleeve 603 to move downward. When the lower end of the hollow circular plate 604 moves to contact the side wall of the electric heating belt, the electric heating belt is fixed between the second sliding plate 9 and the hollow circular plate 604 by the force of the first tension spring 602. When the sleeve 603 retracts, the force applied to the second tension spring 605 is also reduced, so that the baffle 606 can return to the initial position to further fix the electric heating belt from the side to prevent the heating belt from falling off when bending.

[0037] After the electric heating tapes are fixed on the outer walls of the two sleeves 601, the driving motor 502 is started to drive the driving gear 503 to rotate. When the driving gear 503 rotates, the transmission gear 504 can be driven to rotate and then the fixing member 6 can be driven to rotate. When the two fixing members 6 rotate, the fixing member 6 can drive the limiting column 7 to move along the slide groove provided on the bending table 3 through the first sliding plate 8 and the second sliding plate 9. When the limiting column 7 moves, the electric heating tape between the fixing member 6 and the limiting column 7 can be bent, so that the numerical performance of the electric heating tape can be observed through the detector. The bending angle of the electric heating tape can be adjusted by driving the fixing member 6 to rotate by the driving mechanism 5, and the electric heating tape can be bent repeatedly to observe the performance of the electric heating tape.

[0038] Then, the servo motor 402 can be started to drive the bidirectional screw rod 403 to rotate. When the bidirectional screw rod 403 rotates, the two driving mechanisms 5 can be driven to move away from or close to each other, and then the bending table 3 can be driven to move through the fixing member 6 to change the distance between the two sets of bending tables 3. When the distance between the two bending tables 3 is different, the bending degree of the electric heating belt will also change accordingly. At this time, power is turned on again to observe the performance of the electric heating belt under different bending degrees;

[0039] When the electric heating tape passes through between the fixing piece 6 and the limiting column 7 and then bends, the outer wall of the cylinder 702 can always fit the outer side of the electric heating tape to prevent the electric heating tape from falling off during the bending process.

[0040] Preferably, the driving mechanism 5 includes a moving block 501, which is threadedly connected to the slide rail 2, and a driving motor 502 is arranged inside the moving block 501. The output end of the driving motor 502 is fixedly connected to a driving gear 503, and the inner wall of the driving gear 503 is meshingly connected to a transmission gear 504. The lower surface of the transmission gear 504 is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the moving block 501. The upper surface of the transmission gear 504 is fixedly connected to the bottom end of the fixing member 6.

[0041] When in use, after the electric heating tape is set, the driving motor 502 can be used to drive the driving gear 503 to rotate. When the driving gear 503 rotates, the transmission gear 504 meshing therewith can be driven to rotate. The rotation of the transmission gear 504 can drive the fixing part 6 provided with the electric heating tape to rotate. When the fixing part 6 rotates, the second sliding plate 9 can be driven to rotate accordingly. When the second sliding plate 9 rotates, the limiting column 7 can be driven to move along the slide groove on the bending table 3, so that the electric heating tape can be bent. By driving the motor 502 in the forward and reverse directions, the fixing part 6 can be driven to realize a reciprocating rotation action, thereby pulling the electric heating tape to perform regular reciprocating bending. At the same time, with the help of precise control of the rotation angle of the driving gear 503 adjuster, the rotation amplitude of the fixing part 6 can be finely adjusted, thereby realizing flexible adjustment of different bending degrees of the electric heating tape.

[0042] Preferably, the moving mechanism 4 includes a fixed plate 401, two fixed plates 401 are fixedly connected to the upper surface of the workbench 1, one side of one of the fixed plates 401 is fixedly connected to a servo motor 402, the output end of the servo motor 402 is fixedly connected to a bidirectional screw rod 403, both ends of the bidirectional screw rod 403 are respectively rotatably connected to the inner wall of the fixed plate 401, and two driving mechanisms 5 are threadedly connected to the bidirectional screw rod 403.

[0043] During use, when it is necessary to further adjust the bending angle and bending length of the electric heating tape, the servo motor 402 can be started to drive the bidirectional screw rod 403 to rotate. The bidirectional screw rod 403 is provided with threads with opposite directions at both ends, and there is a driving mechanism 5 corresponding to each of the two sections of the thread. When the bidirectional screw rod 403 rotates, the two driving mechanisms 5 can be driven to move closer to or away from each other, thereby mobilizing the two bending tables 3 to move. After moving the bending table 3 to a suitable position according to the required adjustment angle, the driving mechanism 5 is started to drive the fixing part 6 and the limit column 7 to rotate, thereby adjusting the bending angle of the electric heating tape.

[0044] Preferably, the fixing member 6 also includes a sleeve 601, the bottom of the sleeve 601 is fixedly connected to the upper surface of the transmission gear 504, a first tension spring 602 is arranged at the bottom of the sleeve 601, a top opening sleeve 603 is slidably connected to the inner wall of the sleeve 601, a hollow circular plate 604 is fixedly connected to the top of the sleeve 603, a second tension spring 605 is arranged in the hollow circular plate 604 and passes through both sides of the hollow circular plate 604, the other end of the first tension spring 602 is arranged at the center position of the second tension spring 605; two baffles 606 are symmetrically arranged on the outer wall of the hollow circular plate 604, the two baffles 606 are respectively fixedly connected to the two ends of the second tension spring 605, and a circle of grooves is arranged on the hollow circular plate 604 corresponding to the position of the baffle 606 for flipping the baffle 606.

[0045] When in use, the electric heating tape needs to be fixed, and the hollow circular plate 604 needs to be manually pulled up. When the hollow circular plate 604 is pulled, the first tension spring 602 can be stretched. When the first tension spring 602 is pulled, a downward force is applied to the second tension spring 605, so that the two ends of the second tension spring 605 can be moved inward. When moving, the baffles 606 at both ends can be driven to flip upward, so that the baffles 606 leave the outer wall of the hollow circular plate 604. At this time, the electric heating tape to be tested is passed through between the fixing piece 6 and the limiting column 7. Wrapped around the outer wall of the sleeve 601, the hollow circular plate 604 is then loosened to allow the first tension spring 602 to retract and drive the sleeve 603 to move downward. When the lower end of the hollow circular plate 604 contacts the side wall of the electric heating tape, the electric heating tape is fixed between the second sliding plate 9 and the hollow circular plate 604 by the force of the first tension spring 602. When the sleeve 603 retracts, the force applied to the second tension spring 605 is also reduced, so that the baffle 606 can return to the initial position to further fix the electric heating tape from the side.

[0046] When the second tension spring 605 drives the baffles 606 on both sides to flip, the rotation of the baffle 606 will change its position. A circle of grooves is provided on the hollow circular plate 604 at the position corresponding to the baffle 606, so that the baffle 606 will not be stuck when rotating, giving the baffle 606 enough rotation space.

[0047] Preferably, the limiting column 7 includes a connecting column 701, which is slidably connected in a slide groove on the bending table 3, and the lower surface of the connecting column 701 is fixedly connected to a limiting plate 703, and the limiting plate 703 is attached to the lower surface of the bending table 3, and the upper surface of the connecting column 701 is fixedly connected to a cylinder 702.

[0048] When in use, when the fixing part 6 rotates, the second sliding plate 9 can drive the limiting column 7 to slide in the sliding groove of the bending table 3. When the limiting column 7 slides, the first sliding plate 8 is fixed to the outer wall of the connecting column 701. The distance between the first sliding plate 8 and the limiting plate 703 is the same as the thickness of the bending table 3, and the diameter of the limiting plate 703 is larger than the width of the sliding groove, so that the limiting column 7 will not fall off the bending table 3 when sliding. A cylinder 702 is fixed on the upper surface of the connecting column 701. When the fixing part 6 drives the electric heating tape to rotate, the cylinder 702 can always fit with the electric heating tape on the fixing part 6 to prevent the electric heating tape from slipping when bending.

[0049] Preferably, at least four groups of sliders 201 are provided on each slide rail 2 , and every two groups of sliders 201 are fixedly connected to a support plate on one side of the bending table 3 .

[0050] When in use, four sliders 201 are fixed under each bending table 3. When the bidirectional screw rod 403 rotates through the driving mechanism 5 to drive the two bending tables 3 to move closer to or away from each other, the bending table 3 can slide on the slide rail 2 through the slider 201, making the sliding of the bending table 3 smoother.

[0051] Preferably, the first sliding plate 8 and the second sliding plate 9 have the same shape, and are both provided with a fixing hole and a sliding groove, the fixing hole on the second sliding plate 9 matches the sleeve 601, and the fixing hole on the first sliding plate 8 matches the connecting column 701.

[0052] When in use, the positions and sizes of the fixing holes and sliding grooves opened on the first sliding plate 8 and the second sliding plate 9 are the same. The first sliding plate 8 and the second sliding plate 9 overlap each other up and down. The first sliding plate 8 is arranged below the second sliding plate 9 after the second sliding plate 9 is rotated 180 degrees. The second sliding plate 9 is fixed to the fixing piece 6, and the first sliding plate 8 is fixed to the limiting column 7. When the fixing piece 6 rotates to drive the limiting column 7 to move, the limiting column 7 slides in the sliding groove set in the second sliding plate 9. At the same time, the limiting column 7 drives the first sliding plate 8 to displace so that the fixing piece 6 slides in the sliding groove of the first sliding plate 8, which can not only make the limiting column 7 rotate synchronously when the fixing piece 6 rotates, but also prevent the fixing piece 6 and the limiting column 7 from slipping during rotation. In addition, the sliding groove provided can also provide a moving distance for the limiting column 7 when it moves along the cauliflower on the bending table 3.

[0053] Preferably, the inner surface of the baffle 606 and the outer wall of the sleeve 601 are both covered with anti-slip material.

[0054] When in use, the inner side of the baffle 606 and the outer wall of the sleeve 601 are both in contact with the electric heating tape. Covering these two locations with anti-slip material can increase the friction between the baffle 606 and the sleeve 601 and the electric heating tape, further preventing the electric heating tape from falling off during bending detection.

[0055] The present invention provides a device for testing the bending performance of an electric heating tape. The electric heating tape to be tested is wound around the outer wall of the fixing part 6 by means of a fixing part 6, and the first tension spring 602 is stretched by pulling the hollow circular plate 604 upward. When the first tension spring 602 is pulled, the two ends of the second tension spring 605 can be driven to move inward, thereby driving the baffles 606 at both ends to flip upward. At this time, the electric heating tape to be tested can be passed through the fixing part 6 and the limiting column 7 and wound around the outer wall of the sleeve 601. At the same time, the second tension spring 605 also retracts so that the baffle 606 can return to the initial position to further fix the electric heating tape from the side to prevent the electric heating tape from falling off during bending. Then, the driving motor 502 drives the driving gear 503 to rotate, thereby driving the transmission gear 504 to rotate, thereby driving the fixing part 6 rotates, and when both fixing members 6 rotate, the limiting column 7 can be driven to move along the slide groove provided on the bending table 3. When the limiting column 7 moves, the electric heating tape between the fixing member 6 and the limiting column 7 can be bent, so that the numerical performance of the electric heating tape can be observed through the detector. The fixing member 6 is driven to rotate by the driving mechanism 5 to adjust the bending angle of the electric heating tape, and the electric heating tape can be bent repeatedly to observe the performance of the electric heating tape; at the same time, the servo motor 402 can be started to drive the bidirectional screw rod 403 to rotate, and then the two bending tables 3 are driven to move away from or close to each other through the driving mechanism 5, so as to change the distance between the two sets of bending tables 3. When the distance between the two bending tables 3 is different, the bending degree of the electric heating tape will also change accordingly. At this time, power is turned on again to observe the performance of the electric heating tape under different bending degrees.
