Description

Technical Field

[0001] The utility model relates to the technical field of film production, and particularly relates to a sampling device for testing the thermal shrinkage rate of a film. Background Art

[0002] Currently, when testing the thermal shrinkage rate of a film, it is necessary to use a ballpoint pen to draw two mutually perpendicular line segments with a length of 100 mm each along the vertical and horizontal directions on the film, and then put it into an oven at a certain temperature for heating for a certain period of time. After taking it out, the two line segments will shrink to varying degrees, and the shrinkage amount needs to be measured with a ruler to obtain the thermal shrinkage rate. There are several deficiencies in this method:

[0003] When measuring with a ruler, it is necessary to read the value with the naked eye, which is prone to errors. When using a ballpoint pen for scribing, the scribed line of the ballpoint pen is relatively thick and very unclear, which is prone to errors. When scribing, it is necessary to scribe one line at a time and measure the value, which is rather troublesome.

[0004] Therefore, it is necessary to invent a sampling device for testing the thermal shrinkage rate of a film to solve the above problems. Content of the Utility Model

[0022] 4. Metal scribing pen Detailed implementation manners

[0023] As Figures 1-3 shown, the film thermal shrinkage rate test sampling device of the present disclosure may include: a metal base plate 1, two handles 11 are symmetrically arranged at the top end of the metal base plate 1, and a cross-shaped groove 12 is arranged inside the metal base plate 1

[0024] Four corners of the top end of the metal base plate 1 are fixedly connected with support blocks 22, a cross-shaped frame 2 is arranged between the support blocks 22, a moving block 3 is arranged at the top end of the cross-shaped frame 2, a metal scribing pen 4 is arranged at the bottom end of the moving block 3, and a pressing assembly is arranged at the top end of the moving block 3

[0025] Thus, by arranging a cross-shaped groove 12 inside the metal base plate 1, the cross-shaped groove 12 is composed of two cross grooves with a length of 100 mm. By arranging the handle 11, pulling the handle 11 can conveniently drive the metal base plate 1 to move. By arranging the cross-shaped frame 2, the cross-shaped frame 2 is also cross-shaped and arranged at the top end of the cross-shaped groove 12, and is arranged corresponding to the cross-shaped groove 12. Four support blocks 22 are arranged and fixed at the top end of the metal base plate 1. Four ends of the cross-shaped frame 2 are respectively fixed to the support blocks 22. The moving block 3 is arranged at the top end of the cross-shaped frame 2. A metal scribing pen 4 is arranged at the bottom end of the moving block 3. The metal scribing pen 4 can be lifted and lowered and the metal scribing pen 4 can move inside the cross-shaped groove 12, so as to scribe lines on the film arranged at the bottom end of the metal base plate 1

[0026] As Figure 1 shown, in a preferred embodiment, a groove body 21 is arranged inside the cross-shaped frame 2, a slide block 32 is fixedly connected to the bottom end of the moving block 3, and the slide block 32 is slidably connected to the inside of the groove body 21

[0027] Thus, by arranging the slide block 32, the slide block 32 can slide inside the groove body 21. During specific use, pulling the moving block 3 can make the slide block 32 slide inside the groove body 21, effectively limiting the movement of the moving block 3. Thus, the moving block 3 can completely move correspondingly at the top end of the cross-shaped groove 12. A connecting rod 36 is arranged at the bottom end of the connecting plate 35. The connecting rod 36 is fixedly connected to the top end of the metal scribing pen 4. The metal scribing pen 4 is slidably connected to the inside of the slide block 32. A spring 37 is arranged outside the connecting rod 36

[0028] As Figure 2 andFigure 3 As shown, in the present disclosure, the pressing assembly includes a pressing block 31. A pressing rod 33 is fixedly connected to the bottom end of the pressing block 31. The pressing rod 33 is slidably connected to the inside of the moving block 3. A connecting plate 35 is slidably connected to the inside of the moving block 3. The pressing rod 33 is fixedly connected to the top end of the connecting plate 35. Limiting blocks 34 are arranged on both sides of the top end of the connecting plate 35.

[0029] Thus, by providing the pressing block 31 and the pressing rod 33, the pressing block 31 can be effectively pressed to drive the pressing rod 33 to move, thereby driving the connecting plate 35 arranged below to move downward, and then driving the connecting rod 36 and the metal pen 4 arranged below to move downward, so that the metal pen 4 is arranged inside the cross-shaped groove 12 to move, facilitating the scribing work. When the pressing block 31 contacts the moving block 3, the descending height of the pressing block 31 is the lowest. At this time, the metal pen 4 arranged inside the cross-shaped groove 12 is limited, so that the scribing force on the film is constant, effectively improving the accuracy of the scribing work. The connecting rod 36 is arranged at the bottom end of the connecting plate 35. When the pressing block 31 is released, the spring 37 drives the connecting plate 35 to reset, causing the metal pen 4 to move upward, and the pressing block 31 and the pressing rod 33 to rise. The arrangement of the limiting blocks 34 effectively limits the position of the connecting plate 35.

[0030] During specific use, place the film to be scribed at the bottom end of the metal base plate 1. Pull the moving block 3 to move to the outermost side inside the groove body 21. First, move along one line of the cross-shaped frame 2. Press the pressing block 31 to drive the pressing rod 33 to move, thereby driving the connecting plate 35 arranged below to move downward, and then driving the connecting rod 36 and the metal pen 4 arranged below to move downward, so that the metal pen 4 is arranged inside the cross-shaped groove 12. Pull the moving block 3 to move, so that the metal pen 4 completely slides inside the cross-shaped groove 12, facilitating the scribing work on the film surface. Release the pressing block 31, then move the moving block 3 to another cross-shaped frame 2 and move to the outermost side, and complete the above scribing work again, leaving two scribed lines on the film.

[0031] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure, rather than limiting the scope of the present disclosure. For those skilled in the art, other changes or variations can be made based on the above disclosure, and these changes or variations are still within the scope of the present disclosure.
