A screw ring is threaded to the top end of each movable rod. A first spring is sleeved on the movable rod. A connecting rod is fixedly connected to the middle of the upper side of the lifting frame plate. A connecting tube is sleeved on the connecting rod. A pressure plate is fixedly connected to the top end of the connecting tube. A pressure sensor is snapped onto the upper side of the pressure plate. A second spring is sleeved on the connecting tube.

[0006] A middle frame plate is snapped into the middle of the support base, and a CCD camera is snapped into the inner top of the middle frame plate. A horizontal lead screw shaft is passed through the middle of the support base, and a first ball nut is sleeved on the horizontal lead screw shaft. A sliding block is snapped into the outer periphery of the first ball nut, and a connecting hole post is snapped into one side of the sliding block.

[0007] An unwinding roller is installed through the fixed base, and a cover plate is snapped onto the upper side of the fixed base. A winding motor is snapped onto the outer side of the movable base, and a winding shaft is snapped onto the output end of the winding motor.

[0008] As a further embodiment of this utility model: the cross-sectional shape of both the fixed seat and the movable seat is U-shaped, the movable rod is movably connected to the top seat, and the cross-sectional shape of the lifting frame plate is inverted U-shaped.

[0009] As a further embodiment of this utility model: the connecting rod is movably connected to the connecting pipe, the second spring is located between the pressure plate and the lifting frame plate, and the pressure sensor is engaged with the top seat.

[0010] As a further embodiment of this utility model: a movable motor is mounted on one side of the bearing base, and a horizontal lead screw shaft is engaged with the output end of the movable motor. The horizontal lead screw shaft is threadedly connected to the first ball nut. The connecting hole post is movably connected to the bearing base, and the connecting hole post is engaged with the movable seat.

[0011] As a further embodiment of this utility model: a top groove is fixedly connected to the upper side of the intermediate frame plate, a threaded rod is provided through the top groove, a second ball nut is sleeved on the threaded rod, a movable plate is snapped around the second ball nut, fixed connecting plates are fixedly connected to both sides of the movable plate, a limiting groove plate is fixedly connected to the lower end of the two sets of fixed connecting plates, a number of rotating rods are movably connected to the inner side of the limiting groove plate, and a limiting block is fixedly connected to the middle of the lower side of the limiting groove plate.

This replaces the single detection of the existing equipment and realizes multiple detection functions for biodegradable film. The detection process is more convenient.

[0015] Compared with the prior art, the beneficial effects of this utility model include: by rotating the rotary knob at the outer end of the top groove body, the threaded rod is driven to rotate, thereby the two sets of moving plates move relative to each other through the threaded connection between the threaded rod and the second ball nut and the symmetrical threaded section. Then, the two sets of limiting groove plates move relative to each other through the fixed connecting plate, the limiting block and the sliding groove. At this time, several sets of rotating rods are in rolling contact with both sides of the film, which can prevent the film from shifting position during the film winding and inspection process, and ensure the stability of the inspection process.

[0022] Example 1, please refer to Figures 1-4 A testing device for biodegradable film production includes a fixed base 2 fixed to one end of a support base 1, and a movable base 5 disposed on the upper side of the support base 1. A top seat 8 is snapped onto the upper side of the movable base 5. Two sets of movable rods 11 are threaded through the top seat 8. A lifting frame plate 9 is fixedly connected to the lower ends of the two sets of movable rods 11. A movable roller 10 is movably connected to the inner side of the lifting frame plate 9. A threaded ring 12 is threaded to the top end of each movable rod 11. A first spring 13 is sleeved on each movable rod 11. A connecting rod 14 is fixedly connected to the middle of the upper side of the lifting frame plate 9. A connecting pipe 15 is sleeved on the connecting rod 14. A pressure plate 16 is fixedly connected to the top end of the connecting pipe 15. A pressure sensor 17 is snapped onto the upper side of the support base 1, a second spring 18 is sleeved on the connecting pipe 15, a middle frame plate 19 is snapped onto the middle of the support base 1, a CCD camera 20 is snapped onto the inner top of the middle frame plate 19, a horizontal lead screw shaft 22 is passed through the middle of the support base 1, a first ball nut 23 is sleeved on the horizontal lead screw shaft 22, a sliding block 24 is snapped onto the outer periphery of the first ball nut 23, a connecting hole post 25 is snapped onto one side of the sliding block 24, an unwinding roller 3 is passed through the fixed seat 2, and a cover plate 4 is snapped onto the upper side of the fixed seat 2, a winding motor 6 is snapped onto the outer side of the moving seat 5, and a winding shaft 7 is snapped onto the output end of the winding motor 6.

[0023] Both the fixed seat 2 and the movable seat 5 have U-shaped cross-sections. The movable rod 11 is movably connected to the top seat 8. The lifting frame plate 9 has an inverted U-shaped cross-section.

[0024] In this embodiment, the movable rod 11 is movably connected to the top seat 8 to facilitate the lifting and lowering of the lifting frame plate 9.

[0025] The connecting rod 14 is movably connected to the connecting pipe 15, the second spring 18 is located between the pressure plate 16 and the lifting frame plate 9, and the pressure sensor 17 is engaged with the top seat 8.

[0026] In this embodiment, the connecting rod 14 and the connecting tube 15 are used in conjunction to assist in the compression of the second spring 18.

[0027] A movable motor 21 is mounted on one side of the support base 1, and a horizontal lead screw shaft 22 is engaged with the output end of the movable motor 21. The horizontal lead screw shaft 22 is threadedly connected to the first ball nut 23.

[0028] In this embodiment, the sliding block 24 is moved by means of a threaded connection between the horizontal lead screw shaft 22 and the first ball nut 23.

[0029] Specifically, by starting the take-up motor 6 on the movable seat 5, the take-up shaft 7 is driven to rotate, thereby winding the film on the unwind roller 3 onto the take-up shaft 7. As the take-up shaft 7 rotates, the outer diameter of the film roll also increases.

This replaces the single detection function of the existing equipment and realizes multiple detection functions for biodegradable film. The detection process is more convenient.

[0030] Example 2, please refer to Figures 1-4 A testing device for biodegradable film production includes a top groove 26 fixedly connected to the upper side of an intermediate frame plate 19.

Fixed connecting plates 30 are fixedly connected to both sides of the movable plate 29. Limiting groove plates 31 are fixedly connected to the lower ends of the two sets of fixed connecting plates 30. Several sets of rotating rods 32 are movably connected to the inner side of the limiting groove plates 31. A limiting block 33 is fixedly connected to the lower middle of the limiting groove plates 31.

[0031] Both ends of the threaded rod 28 are fixed with rotary knobs 27, and the two sets of rotary knobs 27 are located at both ends of the top groove body 26 respectively.

[0032] In this embodiment, the second ball nut 35 is threadedly connected to the threaded rod 28 to facilitate the movement of the movable plate 29.

[0033] Several sets of rotating rods 32 are evenly distributed on the inner side of the limiting groove plate 31. The fixed connecting plate 30 is L-shaped. The bearing base 1 has two sets of sliding grooves 34 in the middle, and the limiting block 33 is located on the inner side of the sliding groove 34.

[0034] In this embodiment, the limiting block 33 and the sliding groove 34 cooperate to enable the movement of the limiting groove plate 31.

[0035] Specifically, by rotating the rotary knob 27 at the outer end of the top groove body 26, the threaded rod 28 is rotated. This causes the two sets of moving plates 29 to move relative to each other through the threaded connection between the threaded rod 28 and the second ball nut 35, which are symmetrically threaded. Then, through the fixed connecting plate 30, the limiting block 33 and the sliding groove 34 cause the two sets of limiting groove plates 31 to move relative to each other. At this time, several sets of rotating rods 32 are in rolling contact with both sides of the film, which can prevent the film from shifting position during the film winding and inspection process, and ensure the stability of the inspection process.
