[0027] During operation, in the current prior art, although the ion fan 21 and the rolling tube are integrated to eliminate static electricity on the film and reduce the space required for the installation of the static electricity elimination device, the winding roller is rotatably connected to the base. After the film is rolled up, it is necessary to remove the winding roller from the base. However, it is relatively complicated to remove the winding roller, which consumes a lot of time and affects normal work. When removing static electricity from the ground film, one end of the ground film is fixed on the film roll disc 36, and the ground film is placed between the two air outlet pipes 22 and the two guide rollers 12. After the ground film is fixed, the motor 31 and the ion fan 21 are started. The motor 31 drives the film roll disc 36 to rotate, so that the ground film can be rolled up. The two ion fans 21 can eliminate static electricity from the ground film, and the two guide rollers 12 can guide the ground film. After the ground film is destaticized and rolled up, The rod 41 is moved to move the rod 41 out of the slot 45. After the rod 41 is moved out of the slot 45, the mounting block 35 loses its fixation, so that the film reel 36 can be removed. When installing the film reel 36, the rod 41 is moved. During the movement of the rod 41, the positioning ring 42 is driven to move. The movement of the positioning ring 42 will squeeze the spring 43. The spring 43 will shrink under the squeezing and will give a thrust to the positioning ring 42 and the rod 41. After the rod 41 is moved, the mounting blocks 35 at both ends of the film reel 36 are placed in the U-shaped mounting shell 33. After placement, the rod 41 is slowly released. Under the action of the thrust of the spring 43, the rod 41 will be inserted into the mounting block 35, so that the mounting block 35 and the film reel 36 can be fixed. When installing and removing the film reel 36, it is relatively simple, which can save a lot of time and will not affect normal work.

[0028] Further, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the mounting assembly also includes a shell 4 fixedly connected to the outside of the U-shaped mounting shell 33, and an insertion rod 41 is slidably connected to the middle of the shell 4; the positioning ring 42 is located in the shell 4; the spring 43 is fixedly connected to the side of the positioning ring 42 away from the U-shaped mounting shell 33, and the other end of the spring 43 is fixedly connected to the shell 4; the spring 43 is located on the outside of the insertion rod 41; a pull ring 44 is fixedly connected to the end of the insertion rod 41 away from the shell 4; a slot 45 is provided at the position of the mounting block 35 and the U-shaped mounting shell 33 corresponding to the insertion rod 41, and the insertion rod 41 is inserted in the slot 45.

[0029] During operation, after the static electricity elimination work on the ground film is completed, the staff pulls the pull ring 44, and the pull ring 44 drives the insertion rod 41 to move, so that the insertion rod 41 is moved out of the slot 45. After the insertion rod 41 is moved out of the slot 45, the mounting block 35 loses its fixation, so that the film reel 36 can be removed. When installing the film reel 36, the staff pulls the pull ring 44, and the pull ring 44 drives the insertion rod 41 to slide into the housing 4. The sliding process of the insertion rod 41 drives the positioning ring 42 to move, and the movement of the positioning ring 42 presses the spring 43 The spring 43 will shrink when squeezed, and will give a thrust to the positioning ring 42 and the insertion rod 41. After the insertion rod 41 completely slides into the shell 4, the mounting blocks 35 at both ends of the film roll disk 36 are placed into the U-shaped mounting shell 33. After placement, slowly release the pull ring 44. Under the action of the thrust of the spring 43, the insertion rod 41 will be inserted into the slot 45, so that the mounting block 35 and the film roll disk 36 can be fixed. When installing and removing the film roll disk 36, it is relatively simple, which can save a lot of time and will not affect normal work.

[0030] Further, such as Figure 5 and Figure 6 As shown, the mounting block 35 has a first arc surface 46 at a position corresponding to the slot 45 ; the insertion rod 41 has a second arc surface 47 at one end close to the mounting block 35 , and the first arc surface 46 and the second arc surface 47 are used in conjunction with each other.

[0031] During operation, through the No. 1 arc surface 46 opened on the mounting block 35 and the No. 2 arc surface 47 opened on the insertion rod 41, when the insertion rod 41 is inserted into the slot 45, the No. 2 arc surface 47 opened on the insertion rod 41 will first contact the No. 1 arc surface 46 opened on the mounting block 35, thereby facilitating the insertion of the insertion rod 41 into the slot 45.

[0032] Further, such as Figure 4 As shown, the air outlets 23 respectively opened on the two air outlet pipes 22 are arranged opposite to each other.

[0033] During operation, by arranging the air outlets 23 of the two air outlet pipes 22 opposite to each other, the ground film is placed in the middle of the two air outlet pipes 22 when destaticizing the ground film, so that static electricity can be destaticized on both sides of the ground film at the same time.

[0034] Further, such as Figure 1 As shown, the two guide rollers 12 are arranged one above the other, and the two guide rollers 12 are arranged obliquely to each other.

[0035] During operation, the guide rollers 12 are arranged up and down and at an angle, so that the ground film can be guided when the ground film is subjected to static electricity removal.

[0036] Further, such as Figure 2As shown, a bearing 37 is fixedly connected to the third mounting plate 3 close to the rotating rod 34 at a position corresponding to the rotating rod 34 , and the rotating rod 34 is fixedly connected to the middle of the bearing 37 .

[0037] During operation, the rotating rod 34 is fixed to the middle of the bearing 37 through the bearing 37 fixed to the mounting plate, so that the rotating rod 34 can be positioned and supported.

[0038] Working principle:

[0039] When removing static electricity from the ground film, one end of the ground film is fixed on the film rolling disc 36, and the ground film is placed between the two air outlet pipes 22 and the two guide rollers 12. After the ground film is fixed, the motor 31 and the ion fan 21 are started, and the motor 31 drives the film rolling disc 36 to rotate, so that the ground film can be rolled up. The two ion fans 21 can remove static electricity from the ground film, and the two guide rollers 12 can guide the ground film. After the ground film is removed from static electricity and rolled up, the insertion rod 41 is moved to remove the insertion rod 41 from the slot 45. After the insertion rod 41 is moved out of the slot 45, the mounting block 35 loses its fixation, so that the film rolling disc 36 can be removed. During installation, the insertion rod 41 is moved, and the positioning ring 42 is driven to move during the movement of the insertion rod 41. The movement of the positioning ring 42 will squeeze the spring 43, and the spring 43 will shrink under the squeezing, and will give a thrust to the positioning ring 42 and the insertion rod 41. After the insertion rod 41 is moved, the mounting blocks 35 at both ends of the film winding disk 36 are placed in the U-shaped mounting shell 33. After placement, the insertion rod 41 is slowly released. Under the action of the thrust of the spring 43, the insertion rod 41 will be inserted into the mounting block 35, so that the mounting block 35 and the film winding disk 36 can be fixed. When installing and removing the film winding disk 36, it is relatively simple, which can save a lot of time and will not affect normal work.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
