[0027] In actual application, the temperature control box 2 controls the environmental temperature of the medical tape 35 for peel strength test, so that the peel strength test of the medical tape 35 can be carried out at different temperatures; the sticking plate 7 is detached from the carrier 6, then the medical tape 35 is pasted on the sticking plate 7, and then the sticking plate 7 with the medical tape 35 is assembled on the carrier 6; the carrier 6 with the sticking plate 7 is rotated to a required angle, and then the carrier 6 is locked by the angle locking mechanism 8, so that the carrier 6 is locked at a preset angle; then the clamp 14 clamps the port of the release film of the medical tape 35, and then the translation end of the translation driving mechanism 10 drives the sliding rod 9 to move outward, so that the sliding rod 9 with the sliding seat 4 moves along the guide rod frame 3, the sliding seat 4 drives the fixed seat 5, the carrier 6 and the sticking plate 7 to move away from the clamp 14, so that the clamp 14 peels the release film from the tape body of the medical tape 35; in the process that the clamp 14 peels the medical tape 35, the peel strength of the medical tape 35 is applied to the input end of the force sensor 12 through the connecting rod 13, and the force sensor 12 can measure the peel strength in real time.

[0028] In the embodiment, the top surface of the carrier 6 is concave to form a containing cavity 15, both side walls of the containing cavity 15 are concave to form insertion grooves 16, the end wall of the containing cavity 15 close to the clamp 14 is provided with a limiting block 17, the containing cavity 15 is used for containing the sticking plate 7, the insertion grooves 16 are used for inserting the side edge of the sticking plate 7, and the limiting block 17 is used for abutting against one end of the sticking plate 7. In actual application, in the process that the sliding seat 4 drives the fixed seat 5 to move away from the clamp 14 together with the carrier 6 and the sticking plate 7, the limiting block 17 limits the end of the sticking plate 7, so as to ensure the stability of the sticking plate 7 in the containing cavity 15. The structure design not only facilitates the disassembly of the sticking plate 7 and the carrier 6, thereby facilitating the pasting of the medical tape 35 on the sticking plate 7, but also ensures the stability and position accuracy of the sticking plate 7 on the carrier 6.

[0029] In the embodiment, the middle part of the end of the carrier 6 away from the limiting block 17 is concave to form a finger recess 18, and the finger recess 18 is communicated with the containing cavity 15. The finger recess 18 can contain the fingers of an operator, so that the operator can conveniently insert or pull out the sticking plate 7 from the containing cavity 15.

[0030] In the embodiment, the angle locking mechanism 8 comprises two adapter plates 19 symmetrically arranged on the fixed seat 5, a rotating shaft 20 rotatably connected to the two adapter plates 19, and a locking structure 21 arranged on the fixed seat 5 and used for locking the rotating shaft 20, and the bottom surface of one end of the carrier 6 is arranged on the circumferential wall of the rotating shaft 20.

[0031] When it is necessary to adjust the angle of the carrier 6 and the adhesive plate 7, the locking structure 21 releases the rotating shaft 20, drives the rotating shaft 20 or the carrier 6 to rotate, so as to adjust the angle of the carrier 6. When the angle of the carrier 6 reaches the preset angle, the locking structure 21 locks the rotating shaft 20 to fix the angle of the carrier 6. This structural design facilitates the adjustment of the angle of the carrier 6 and the adhesive plate 7.

[0032] In this embodiment, the locking structure 21 includes a locking plate 22 and a locking bolt 23. The locking plate 22 is mounted on the fixing base 5 and located on one side of an adapter plate 19. A locking hole 24 is provided in the middle of the locking plate 22 in the thickness direction. An open deformation groove 25 is provided in the middle of the locking plate 22 in the height direction, penetrating the locking hole 24. A through hole 26 and a threaded hole 27 are coaxially provided on the top of the locking plate 22 in the length direction. The through hole 26 and the threaded hole 27 are located on both sides of the open deformation groove 25, respectively. One end of the rotating shaft 20 rotates through an adapter plate 19 and is inserted into the locking hole 24. The screw of the locking bolt 23 passes through the through hole 26 and is threadedly connected to the threaded hole 27.

[0033] In practical applications, one end of the rotating shaft 20 is inserted into the lock hole 24. The screw of the locking bolt 23 passes through the through hole 26 and is threaded into the threaded hole 27 to lock the rotating shaft 20 into the lock hole 24 of the locking plate 22, thereby fixing the angle of the carrier 6. When it is necessary to adjust the angle of the carrier 6, the locking bolt 23 is loosened, causing the opening deformation groove 25 of the locking plate 22 to slightly enlarge under the action of the spring force, so that the end of the rotating shaft 20 can rotate in the lock hole 24, thereby achieving the angle adjustment of the carrier 6. After adjustment, the locking bolt 23 is tightened, causing the opening deformation groove 25 of the locking plate 22 to gradually shrink until the lock hole 24 of the locking plate 22 locks the rotating shaft 20. This structural design facilitates the angle adjustment and locking of the carrier 6.

[0034] Specifically, the nut of the locking bolt 23 is provided with a handle 37. The handle 37 is for the operator's hand to operate, so that the operator can drive the locking bolt 23 to rotate through the handle 37 to tighten the locking bolt 23.

[0035] In this embodiment, the outer wall of another adapter plate 19 is provided with an angle scale line 38. The other end of the rotating shaft 20 rotates through the adapter plate 19 and is fixedly connected to the indicator needle 39. The indicator needle 39 is used to indicate the angle value corresponding to the angle scale line 38. When adjusting the angle of the carrier 6, the carrier 6 and the rotating shaft 20 rotate synchronously, and the indicator needle 39 on the rotating shaft 20 will indicate the angle value on the angle scale line 38, so that the operator can accurately adjust the angle of the carrier 6.

[0036] The angle locking mechanism 8 further comprises a base 28 arranged on the fixing base 5, a spring positioning pin 29 arranged on the base 28, and a horizontal block 30 arranged on the bottom surface of the carrier 6, one side of the horizontal block 30 is provided with a positioning hole for the spring positioning pin 29 to be inserted into, and the bottom surface of the horizontal block 30 is used to abut against the top surface of the fixing base 5.

[0037] When it is needed to adjust the carrier 6 and the sticking plate 7 to be horizontal, the bottom surface of the horizontal block 30 is flush with the top surface of the fixing base 5, the spring positioning pin 29 is elastically inserted into the positioning hole to lock the horizontal block 30, so as to position the carrier 6, and then the rotating shaft 20 is locked, so as to further ensure the position accuracy and stability of the carrier 6 in the horizontal state.

[0038] In the embodiment, the translation end of the translation driving mechanism 10 is connected to the end of the slide rod 9 away from the slide base 4 through the universal joint 31. By connecting the translation end of the translation driving mechanism 10 and the slide rod 9 through the universal joint 31, the slide rod 9 can be prevented from being subjected to eccentric force, thereby protecting the slide rod 9.

[0039] In the embodiment, the top surface of the machine table 1 is provided with an outer cover 32, and the outer cover 32 covers the translation driving mechanism 10. The structure design can protect the translation driving mechanism 10 and has an attractive appearance.

[0040] In the embodiment, the temperature control box 2 is made of heat preservation material, and the temperature control box 2 comprises a box body 33 and a box door 34. The box body 33 is arranged on the machine table 1, one side of the box door 34 is rotationally connected to one side of the side opening of the box body 33, the other side of the box door 34 is detachably and sealingly connected to the other side of the side opening of the box body 33, and a transparent observation window 36 is arranged in the middle of the box door 34. The transparent observation window 36 is used for the operator to observe the situation of the peeling force test in the temperature control box 2 in real time.

[0041] All the technical features in the embodiment can be freely combined according to actual needs.
