Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to a tension testing device for adhesive tape production. Background Technology

[0002] Adhesive tape is a strip of material coated with adhesive, used to connect or fix objects. It consists of a substrate and an adhesive and is widely used in daily life and industry. Adhesive tape is a strip product composed of a substrate such as plastic film, cloth, paper, etc. and an adhesive. It can bond the surface of objects by applying pressure without heating or curing. Its core principle is that the adhesive molecules form bonds with the molecules of the adhered object, thereby achieving a strong bond.

[0003] For example, a tension detection device for electronic tape production, as described in patent publication number CN218156622U, has the following key technical features: It includes a base, on which a mounting plate is fixedly connected. Multiple tensioning rollers are fixedly connected to the side of the mounting plate. A movable frame is slidably connected to the side of the mounting plate. Two limiting members for fixing the electronic tape are provided within the movable frame. A support frame is fixedly installed on the top surface of the mounting plate, and a pressure sensor is fixedly installed on the support frame above the movable frame. This tension detection device for electronic tape production, through the arrangement of the movable frame, connecting rod one, connecting rod two, a turntable, and a fixed shaft, achieves tension detection of the electronic tape. The process is simple and easy to operate, thus solving the problem in existing technologies where the movement of two tensioning rollers is required, making the process cumbersome and the work difficult.

[0004] In the aforementioned prior art, the tension of the tape is tested by manual drive. When workers need to test a large number of tapes, the frequent manual operation of the equipment can easily cause numbness and tingling in the workers' hands, and may also lead to occupational diseases of the hands. This increases the workload for workers and reduces the practicality and testing efficiency of the equipment. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5 This utility model provides a tension testing device for tape production, including a mounting plate 1 and a base plate 101 fixedly connected to the bottom of the mounting plate 1. A fixing plate 2 is fixedly connected to the top of the base plate 101 on the side away from the mounting plate 1. A movable frame 3 is provided on the opposite side of the mounting plate 1 and the fixing plate 2. A box body 4 is fixedly connected to the surface of the base plate 101. An automatic drive component is provided on one side of the box body 4, and a manual drive component is provided on the other side of the box body 4. An adjustment mechanism is provided on the top of the base plate 101. An installation groove is opened on the top of the box body 4, and a sealing plate 29 is snapped into the inner wall of the installation groove.

[0032] First, the tape to be tensioned is wrapped around the movable frame 3 and the tensioning roller. Then, the automatic drive mechanism inside the housing 4 is activated, causing the adjustment mechanism to work and drive the movable frame 3 upward. This causes the movable frame 3 to move the tape upward, pressing the pressure sensor on the top of the mounting plate 1. The pressure sensor value is observed to complete the detection of tape tension. This effectively solves the problem that existing equipment requires manual operation for a long time, which increases the labor intensity of the workers and reduces the practicality and detection efficiency of the equipment. In addition, if the automatic drive mechanism inside the housing 4 is damaged, the workers can use the manual drive mechanism to drive the equipment, ensuring that the equipment can work normally in an emergency, further increasing the practicality of the equipment. Furthermore, if the parts inside the housing 4 are damaged, the sealing plate 29 that is snapped in the mounting slot can be removed, and then the parts inside the housing 4 can be repaired.

[0033] The adjustment mechanism includes a groove 5 on the top of the base plate 101, and grooves 7 on opposite sides of the mounting plate 1 and the fixing plate 2 that penetrate the groove 5. A drive shaft 6 is rotatably connected to the groove 5 and extends into the box body 4. A movable lead screw 8 is provided on the top of the inner wall of the groove 7. A bevel gear 10 is fixedly connected to the bottom of the movable lead screw 8. A bevel gear 9 is fixedly connected to the outer contour of the drive shaft 6 near the bevel gear 10 and meshes with the bevel gear 10. A lead screw slider 81 is provided on the outer contour of the movable lead screw 8. The side of the lead screw slider 81 near the movable frame 3 is fixedly connected to the movable frame 3.

[0034] By utilizing the automatic or manual drive mechanism within the housing 4, the drive shaft 6 within the groove 5 rotates. As the drive shaft 6 rotates, it also drives the bevel gear 9 on the drive shaft 6 to rotate. Then, the bevel gear 10 meshing with the bevel gear 9 rotates, which in turn drives the movable lead screw 8 to rotate. The movable lead screw 8 then drives the lead screw slider 81 to move upward within the groove 7. The lead screw slider 81 then drives the movable frame 3 to move upward, causing the movable frame 3 to move the tape upward. The upward movement of the movable frame 3 presses against the pressure sensor on the top of the mounting plate 1. The pressure sensor reading is observed to complete the detection of the tape tension.

[0035] The automatic drive unit includes a motor 11 fixedly connected to the inner wall of the housing 4, a connecting shaft 12 fixedly connected to the end of the motor 11, a drive gear 13 fixedly connected to the outer contour of the connecting shaft 12, a movable shaft 14 slidably connected to the inner cavity of the drive shaft 6, a driven gear 15 fixedly connected to the outer contour of the movable shaft 14, and a snap-fit ​​rod 16 circumferentially arranged on the movable shaft 14 near the inner cavity of the drive shaft 6, and a snap-fit ​​groove 17 adapted to the snap-fit ​​rod 16 is opened on the inner wall of the drive shaft 6.

[0036] The starting motor 11 drives the drive gear 13 on the connecting shaft 12 to rotate. The drive gear 13 drives the driven gear 15 on the movable shaft 14 to rotate. Then, the driven gear 15 drives the locking rod 16 on the movable shaft 14 to rotate. Because the locking rod 16 engages with the locking groove 17 opened on the inner wall of the drive shaft 6, when the drive gear 13 rotates, the driven gear 15 also rotates. The rotating driven gear 15 drives the movable shaft 14 and the drive shaft 6 to rotate. The rotating drive shaft 6 causes the adjustment mechanism to drive the movable frame 3 to work.

[0037] The manual drive component includes a rotating shaft 18 rotatably connected to the housing 4. One end of the rotating shaft 18 is fixedly connected to a drive gear 19, and the other end of the rotating shaft 18 is fixedly connected to a handle 20. An adjusting component is provided on the outer contour of the movable shaft 14 away from the locking rod 16. The adjusting component includes a bearing 22 provided on the outer contour of the movable shaft 14 away from the locking rod 16. An adjusting plate 21 is fixedly connected to the outer contour of the bearing 22. A telescopic slider 24 is provided on the top of the adjusting plate 21. A sliding groove 26 for the housing 4 to be limited and slidably connected is provided on the top of the telescopic slider 24. An adjusting block 23 is fixedly connected to the top of the telescopic slider 24. A sliding groove 26 for the telescopic slider 24 to be limited and slidably connected is provided on the top of the housing 4. Locking blocks 28 are fixedly connected to both sides of the bottom of the adjusting block 23. A locking groove 27 for the locking blocks 28 to be engaged is provided on the top of the housing 4.

[0038] After motor 11 is damaged, the upward movement of adjusting block 23 causes telescopic slider 24 to move out of placement slot 25, so that the locking block 28 at the bottom of adjusting block 23 moves out of the slot 27 on the box 4. At this time, the operator pulls adjusting block 23 to move telescopic slider 24 in sliding slot 26. When telescopic slider 24 moves, it also moves adjusting plate 21. By moving adjusting plate 21, bearing 22 and the movable shaft 14 on the inner wall of bearing 22 move, so that movable shaft 14 moves out of drive shaft 6. When adjusting block 23 can no longer move, the driven gear 15 on movable shaft 14 pulled out of drive shaft 6 and the rotating shaft The second driving gear 19 on shaft 18 engages, thereby disengaging the first driving gear 13 from the driven gear 15. Then, the handle 20 is rotated, causing the second driving gear 19 on shaft 18 to rotate. Because the locking rod 16 engages with the locking groove 17 on the inner wall of the drive shaft 6, the rotation of the second driving gear 19 also drives the driven gear 15 on the movable shaft 14 to rotate. The rotating driven gear 15 drives the drive shaft 6 to rotate, thereby enabling the adjustment mechanism to work. This allows the equipment to work in emergencies, avoiding the problem of reduced detection efficiency due to equipment damage, and further increasing the practicality of the equipment.

[0039] Working principle: First, the starting motor 11 drives the drive gear 13 on the connecting shaft 12 to rotate. The drive gear 13 drives the driven gear 15 on the movable shaft 14 to rotate. Then, the driven gear 15 drives the locking rod 16 on the movable shaft 14 to rotate. Because the locking rod 16 engages with the locking groove 17 on the inner wall of the drive shaft 6, the rotation of the drive gear 13 also causes the driven gear 15 to rotate. The rotating driven gear 15 drives the movable shaft 14 and the drive shaft 6 to rotate. The rotating drive shaft 6 in the groove 5 drives the bevel gear 9 on the drive shaft 6 to rotate. Then, the bevel gear 10 meshing with the bevel gear 9 rotates. The bevel gear 10 drives the movable lead screw 8 to rotate. The movable lead screw 8 drives the lead screw slider 81 to move upward in the groove 7. Then, the lead screw slider 81 drives the movable frame 3 to move upward. The movable frame 3 drives the tape to move upward. The upward movement of the movable frame 3 presses the pressure sensor on the top of the mounting plate 1. The value of the pressure sensor is observed to complete the detection of the tape tension.

[0040] After motor 11 is damaged, the upward movement of adjusting block 23 causes telescopic slider 24 to move out of placement slot 25, so that the locking block 28 at the bottom of adjusting block 23 moves out of the slot 27 on the box 4. At this time, the operator pulls adjusting block 23 to move telescopic slider 24 in sliding slot 26. When telescopic slider 24 moves, it also moves adjusting plate 21. By moving adjusting plate 21, bearing 22 and the movable shaft 14 on the inner wall of bearing 22 move, so that movable shaft 14 moves out of drive shaft 6. When adjusting block 23 can no longer move, it is pulled out of drive shaft 6. The driven gear 15 on the movable shaft 14 meshes with the driving gear 19 on the rotating shaft 18, thereby causing the driving gear 13 and the driven gear 15 to disengage. Then, the handle 20 is rotated, causing the handle 20 to drive the driving gear 19 on the rotating shaft 18 to rotate. Because the locking rod 16 engages with the locking groove 17 opened on the inner wall of the drive shaft 6, when the driving gear 19 rotates, it also drives the driven gear 15 on the movable shaft 14 to rotate. The rotating driven gear 15 drives the drive shaft 6 to rotate, thereby making the adjustment mechanism work and enabling the equipment to work in an emergency.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
