DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0027] like Figure 1-3As shown, in this embodiment, it includes a detection box 1 and a display screen 2, the display screen 2 is installed outside the detection box 1, and a heat preservation partition 3 is fixed at the middle end of the detection box 1. The heat preservation partition 3 has a through hole extending from top to bottom, and the lower end of the through hole of the heat preservation partition 3 is covered with a lower heat preservation cover 6, and an upper heat preservation cover 5 is arranged above the lower heat preservation cover 6. Two support rods 21 distributed left and right are fixed between the upper heat preservation cover 5 and the lower heat preservation cover 6, and a slide bar 14 is fixed between the two support rods 21. The outer periphery of the slide bar 14 is slidably sleeved with a pull plate 10, and a tape clamping assembly is arranged on the right side of the pull plate 10, and the tape clamping assembly includes a tension sensor 8 , concave plate 11, clamping plate 18 and bidirectional screw 19, the tension sensor 8 is fixed to the inner side of one of the support rods 21, the concave plate 11 is provided with two pieces, one of which is connected to the sensing end of the tension sensor 8, and the other concave plate 11 is fixed to the right side of the pull plate 10, the clamping plates 18 are provided with two pieces in each concave plate 11, the clamping plates 18 are slidably connected with the concave plates 11, the bidirectional screw 19 rotates from top to bottom and passes through the concave plate 11, the clamping plates 18 are threadedly sleeved with the bidirectional screw 19, the inner side of the clamping plates 18 are connected with latch teeth, and the latch teeth at the upper and lower ends are staggered left and right.

[0028] When the detection device is used to detect the tearing of the tape, first place the two ends of the tape one by one in the two concave plates 11, and make the tape located between the upper and lower clamping plates 18, then turn the bidirectional screw 19 to drive the upper and lower clamping plates 18 to slide along the concave plates 11. During this process, the upper and lower clamping plates 18 approach each other and clamp the tape. Since the inner side of the clamping plates 18 is connected with the latch teeth, the tape is clamped by the latch teeth, which helps to improve the firmness of the tape after clamping, until the two ends of the tape are completely clamped, so as to prevent the tape from accidentally falling off during the tear detection process.

[0029] like Figure 2 As shown, in this embodiment, a sliding drive assembly is provided between the two support rods 21, and the sliding drive assembly includes a forward and reverse motor 12 and a one-way screw 13. The forward and reverse motor 12 is fixed to the inner side of the other support rod 21, one end of the one-way screw 13 is connected to the power end of the forward and reverse motor 12, and the other end of the one-way screw 13 is rotatably connected to the inner side of one of the support rods 21, and the pull plate 10 is threadedly sleeved with the one-way screw 13.

[0030] Then, the one-way screw rod 13 is driven to rotate through the work of the forward and reverse motor 12, and the one-way screw rod 13 will drive the pull plate 10 to move left along the slide rod 14. Since the pull plate 10 will drive the concave plate 11 fixed thereto to move left, the clamped tape will be pulled, and the concave plate 11 on the right will apply tension to the tension sensor 8, so as to detect the tearing of the tape. When the tape is pulled and torn, the tension sensor 8 measures the tension during the pulling. Under the premise that the tension sensor 8 is set to be connected to the signal of the display screen 2, the display screen 2 displays the measured tension value. In summary, it is conducive to real-time detection of the tearing condition of the tape when it is subjected to different tensions. Compared with the existing technology, it is conducive to accurately measuring the tearing resistance of the tape under various tensions, thereby reducing the detection error and ensuring the accuracy of the detection result.

[0031] like Figure 2 As shown, in this embodiment, the upper left end of the detection box 1 is connected to a refrigerator 4, and the lower end of the upper insulation cover 5 is fixed with a temperature sensor 9.

[0032] When it is necessary to detect the tearing ability of the tape in a relatively low temperature environment, the lower insulation cover 6 covers the opening of the insulation partition 3, and then the cold air is transported to the upper end of the detection box 1 through the refrigerator 4. Therefore, the interior of the detection box 1 is divided into upper and lower layers based on the insulation partition 3 and the lower insulation cover 6, and a low-temperature detection chamber is formed in the upper layer of the detection box 1. At the same time, the temperature sensor 9 detects the temperature of the detection environment, which is conducive to the tearing detection of the tape in various relatively low temperature environments, and effectively ensures the reliability of the detection results.

[0033] like Figure 4 As shown, in this embodiment, a hot air blower 17 is connected to the lower left end of the detection box 1, and a lifting drive assembly is provided above the thermal insulation partition 3, and the lifting drive assembly includes a screw motor 15, a lifting screw 16 and a guide rod 7. The screw motor 15 is fixed to the upper end of the detection box 1, and one end of the lifting screw 16 is connected to the power end of the screw motor 15. The lifting screw 16 rotates downward and penetrates into the detection box 1, and the other end of the lifting screw 16 is rotatably connected to the upper end of the thermal insulation partition 3. The upper thermal insulation cover 5 is threadedly sleeved with the lifting screw 16, and the guide rod 7 is fixed between the upper end of the thermal insulation partition 3 and the top of the detection box 1, and the upper thermal insulation cover 5 is slidably sleeved with the guide rod 7.

[0034] When it is necessary to detect the tearing ability of the adhesive tape in a higher temperature environment, the lifting screw 16 is driven to rotate through the work of the screw motor 15, and the lifting screw 16 will drive the upper insulation cover 5 to slide downward along the guide rod 7, and at the same time, the upper insulation cover 5 drives the support rod 21 and the lower insulation cover 6 to move downward until the upper insulation cover 5 covers the opening of the insulation partition 3. At this time, the interior of the detection box 1 is divided into an upper and lower layer based on the insulation partition 3 and the upper insulation cover 5, and a high-temperature detection chamber is formed in the lower layer of the detection box 1, and hot air is input into the lower end of the detection box 1 through the hot air blower 17, so that a detection chamber with a relatively high temperature is formed in the lower layer of the detection box 1 for detection. At the same time, the temperature sensor 9 detects the temperature of the detection environment, which is conducive to the tearing detection of the adhesive tape in various high-temperature environments. In summary, compared with the prior art, the present technical solution is conducive to detecting the tearing resistance of the adhesive tape in different temperature environments, and the data after detection is more reliable.

[0035] like Figure 1 As shown, in this embodiment, the upper and lower parts of the front end of the detection box 1 are covered with box doors 20, and the box door 20 is made of hollow glass.

[0036] During the detection process, the box door 20 made of hollow glass covers the detection box 1 to prevent the temperature in the detection box 1 from overflowing. Through the box door 20 made of hollow glass, the staff can intuitively check the status of the tape tearing detection in the detection box 1, thereby ensuring the normal progress of the detection work.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
