[0022] The present invention also discloses a method for using an antistatic film cutting device that is easy to position, comprising the following steps:

[0023] S1. After the antistatic film is placed on the top surface of the base, the forward and reverse motors are started, and one end of the output shaft of the forward and reverse motors drives the driving rod to rotate. The driving rod drives the first bevel gear to rotate while the driving rod rotates. The first bevel gear is meshed with the second bevel gear, so that the first bevel gear rotates while the second bevel gear rotates synchronously. The second bevel gear drives the second transmission rod to rotate. The second transmission rod drives the first transmission rod to rotate through the pulley and the belt while the second transmission rod rotates. The first transmission rod and the second transmission rod drive the threaded rod to rotate while the threaded rod is threadedly connected to the inner wall of the limiting threaded cylinder.

[0024] S2, when the threaded rod rotates, it drives the limiting threaded cylinder to move downward on its outer wall, and the limiting threaded cylinder moves downward, and the first positioning pressure plate moves downward, and the second positioning pressure plate moves downward, and the first positioning pressure plate and the second positioning pressure plate move simultaneously, and the friction increasing strip moves simultaneously, so that it can position and press the antistatic film placed on the top surface of the base, and when the cutting size of the antistatic film needs to be adjusted, it is only necessary to pull the handle upward, and the handle moves simultaneously, and the pull rod moves simultaneously, and the pull rod moves simultaneously, and the fixed plate moves simultaneously, and one end of the first spring arranged on the outer wall of the pull rod is squeezed simultaneously, so that the first spring is compressed;

[0025] S3, the displacement of the fixed plate also drives the pin to move, so that the pin is moved out of the socket provided on the size adjustment plate. At this time, the fixed mode of the size adjustment plate is released, and the size adjustment plate can be telescopically adjusted on the inner wall of the stroke groove provided at the bottom of the first positioning pressure plate, so as to adjust the size of the antistatic film pressed on the base, thereby adjusting the cutting size of the antistatic film. After long-term use of the quick-setting component, the friction strips installed in the mounting grooves provided at the bottom of the first positioning pressure plate, the second positioning pressure plate and the size adjustment plate will be worn, which will greatly reduce the positioning effect. At this time, the two ends of the old friction strip can be held by hand and pulled upward, and the semicircular block provided on the side wall of the mounting groove will slide out of the groove provided on the side wall of the old friction strip. The semicircular block squeezes the second spring at this time, so that the second spring forms a compressed state, and the telescopic rod is in a contracted state at the same time, so that the old friction strip can be moved out of the mounting groove, and the semicircular block will be reset after it is moved out;

[0026] S4, replace the newly added friction bar, and first align the newly added friction bar with the mounting grooves provided at the bottom of the first positioning pressure plate, the second positioning pressure plate and the size adjustment plate to press them downward, and the side wall of the newly added friction bar will squeeze the semicircular block, and the semicircular block will squeeze the second spring at this time, so that the second spring is in a compressed state, and the telescopic rod is in a contracted state at the same time, until the semicircular block slides into the groove provided on the side wall of the newly added friction bar to fix the newly added friction bar.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, a quick-setting component is provided, and when the antistatic film is placed on the top surface of the base, the forward and reverse motors are started, and one end of the output shaft of the forward and reverse motors drives the driving rod to rotate. When the driving rod rotates, the first bevel gear is driven to rotate, and the first bevel gear is meshed with the second bevel gear, so that the first bevel gear rotates and the second bevel gear is driven to rotate synchronously, and the second bevel gear drives the second transmission rod to rotate. When the second transmission rod rotates, the first transmission rod is driven to rotate through the pulley and the belt. When the first transmission rod and the second transmission rod rotate, the threaded rod is driven to rotate, and the outer wall of the threaded rod is threadedly connected to the inner wall of the limiting threaded cylinder. When the threaded rod rotates, When the limit threaded barrel is displaced downward on its outer wall, the limit threaded barrel is displaced and the first positioning pressure plate is displaced downward. The first positioning pressure plate is displaced and the second positioning pressure plate is displaced. The first positioning pressure plate and the second positioning pressure plate are displaced and the friction increasing bar is displaced to position and press the antistatic film placed on the top surface of the base. Through this design, the antistatic film placed on the top surface of the base is effectively positioned quickly, the operation process is simplified, and there is no need for long preparation work in the early stage. The cutting efficiency of the antistatic film is greatly increased, thereby increasing the output rate of the antistatic film cutting device and having a good use effect.

[0029] 2. In the present invention, a size adjustment component is provided. When the cutting size of the antistatic film needs to be adjusted, the handle only needs to be pulled upwards. The displacement of the handle drives the displacement of the pull rod, and the pull rod drives the displacement of the fixed plate. When the fixed plate is displaced, one end of the first spring provided on the outer wall of the pull rod is squeezed, so that the first spring is compressed. During the displacement of the fixed plate, the latch is also driven to move, so that the latch is moved out of the insertion hole provided on the size adjustment plate. At this time, the fixed mode of the size adjustment plate is released, and the size adjustment plate can be telescopically adjusted on the inner wall of the stroke groove provided at the bottom of the first positioning pressure plate, so as to adjust the size of the antistatic film pressed on the base, thereby realizing the adjustment of the cutting size of the antistatic film. Through this design, the quick-setting component can be effectively and quickly adjusted in size, thereby realizing the cutting of different sizes of the antistatic film, which greatly improves the practicality and has a good use effect.

[0030] 3. In the present invention, by providing a fixing component, after long-term use of the quick-setting component, the friction strips installed in the mounting grooves provided at the bottom of the first positioning pressure plate, the second positioning pressure plate and the size adjustment plate will be worn, which will greatly reduce the positioning effect. At this time, the two ends of the old friction strip can be held by hand to pull it upward, and the semicircular block provided on the side wall of the mounting groove will slide out of the groove provided on the side wall of the old friction strip. The semicircular block will squeeze the second spring at this time, so that the second spring forms a compressed state, and the telescopic rod is in a contracted state at the same time, so that the old friction strip can be removed from the mounting groove. After it is removed, the semicircular block will be reset, and the new friction strip can be replaced. The newly added friction strip is first aligned with the mounting grooves provided at the bottom of the first positioning pressure plate, the second positioning pressure plate and the size adjustment plate to press them downward, and the side wall of the newly added friction strip will squeeze the semicircular block, and the semicircular block will squeeze the second spring at this time, so that the second spring is in a compressed state, and the telescopic rod is in a contracted state at the same time, and the semicircular block slides into the groove provided on the side wall of the newly added friction strip to fix the newly added friction strip. Through this design, the friction strips on the quick-fix assembly can be quickly replaced, which improves the cutting effect of the antistatic film during the later cutting of the antistatic film, avoids affecting the later cutting effect of the equipment, and has a good use effect.

[0049] The present invention also discloses a method for using an antistatic film cutting device that is easy to position, comprising the following steps:

[0050] S1. After the antistatic film is placed on the top surface of the base 1, the forward and reverse motor 41 is started, and one end of the output shaft of the forward and reverse motor 41 drives the driving rod 42 to rotate. When the driving rod 42 rotates, the first bevel gear 413 is driven to rotate. The first bevel gear 413 is meshed with the second bevel gear 414, so that the first bevel gear 413 rotates and the second bevel gear 414 is driven to rotate synchronously. The second bevel gear 414 drives the second transmission rod 412 to rotate. When the second transmission rod 412 rotates, the first transmission rod 43 is driven to rotate through the pulley 44 and the belt 45. When the first transmission rod 43 and the second transmission rod 412 rotate, the threaded rod 46 is driven to rotate. The outer wall of the threaded rod 46 is threadedly connected with the inner wall of the limiting threaded cylinder 47.

[0051] S2. When the threaded rod 46 rotates, it drives the limiting threaded cylinder 47 to move downward on its outer wall. When the limiting threaded cylinder 47 moves, it drives the first positioning pressure plate 48 to move downward. When the first positioning pressure plate 48 moves, it drives the second positioning pressure plate 49 to move. When the first positioning pressure plate 48 and the second positioning pressure plate 49 move, they drive the friction increasing strip 411 to move, so that it can position and press the antistatic film placed on the top surface of the base 1. When the cutting size of the antistatic film needs to be adjusted, it only needs to pull the handle 54 upward. When the handle 54 moves, it drives the pull rod 55 to move. The pull rod 55 drives the fixed plate 57 to move. When the fixed plate 57 moves, one end of the first spring 56 provided on the outer wall of the pull rod 55 is squeezed, so that the first spring 56 is compressed.

[0052] S3, the process of the fixed plate 57 moving also drives the pin 58 to move, so that the pin 58 is moved out of the insertion hole set on the size adjustment plate 52. At this time, the size adjustment plate 52 is released from the fixed mode, and the size adjustment plate 52 can be telescopically adjusted on the inner wall of the stroke groove 51 set at the bottom of the first positioning plate 48, so as to adjust the size of the antistatic film pressed on the base 1, thereby adjusting the cutting size of the antistatic film. After long-term use of the quick-setting component 4, the first positioning plate 48, the second positioning plate 49 and the bottom of the size adjustment plate 52 are set The friction strip 411 installed in the installation groove 410 will be worn, which will greatly reduce the positioning effect. At this time, the two ends of the old friction strip 411 can be held by hand to pull it upward, and the semicircular block 61 provided on the side wall of the installation groove 410 will slide out of the groove provided on the side wall of the old friction strip 411. The semicircular block 61 will squeeze the second spring 63 at this time, so that the second spring 63 is in a compressed state, and the telescopic rod 62 is in a contracted state at the same time, so that the old friction strip 411 can be moved out of the installation groove 410, and the semicircular block 61 will be reset after it is moved out;

[0053] S4, replace the newly added friction bar 411, and the newly added friction bar 411 is first aligned with the first positioning plate 48, the second positioning plate 49 and the mounting groove 410 provided at the bottom of the size adjustment plate 52, so that it is pressed downward, and the side wall of the newly added friction bar 411 will squeeze the semicircular block 61, and the semicircular block 61 will squeeze the second spring 63 at this time, so that the second spring 63 is in a compressed state, and the telescopic rod 62 is in a contracted state at the same time, until the semicircular block 61 slides into the groove provided on the side wall of the newly added friction bar 411, and the newly added friction bar 411 is fixed.

[0054] Working principle: when the antistatic film is placed on the top surface of the base 1, the forward and reverse motor 41 is started, and one end of the output shaft of the forward and reverse motor 41 drives the driving rod 42 to rotate. When the driving rod 42 rotates, the first bevel gear 413 is driven to rotate. The first bevel gear 413 is meshed with the second bevel gear 414, so that the first bevel gear 413 rotates and the second bevel gear 414 is driven to rotate synchronously. The second bevel gear 414 drives the second transmission rod 412 to rotate. When the second transmission rod 412 rotates, the first transmission rod 43 is driven to rotate through the pulley 44 and the belt 45. When the first transmission rod 43 and the second transmission rod 412 rotate, the threaded rod 46 is driven to rotate. The outer wall of the threaded rod 46 is threadedly connected with the inner wall of the limiting threaded cylinder 47. When the threaded rod 46 rotates, the threaded rod 46 is threadedly connected with the inner wall of the limiting threaded cylinder 47. When the rod 46 rotates, it drives the limiting threaded cylinder 47 to move downward on its outer wall. When the limiting threaded cylinder 47 moves, it drives the first positioning pressure plate 48 to move downward. When the first positioning pressure plate 48 moves, it drives the second positioning pressure plate 49 to move. When the first positioning pressure plate 48 and the second positioning pressure plate 49 move, they drive the friction increasing bar 411 to move, so that it can position and press the antistatic film placed on the top surface of the base 1. When the cutting size of the antistatic film needs to be adjusted, it only needs to pull the handle 54 upward. When the handle 54 moves, it drives the pull rod 55 to move. The pull rod 55 drives the fixed plate 57 to move. When the fixed plate 57 moves, one end of the first spring 56 arranged on the outer wall of the pull rod 55 is squeezed, so that the first spring 56 is compressed. , the process of displacement of the fixing plate 57 also drives the pin 58 to move, so that the pin 58 is moved out of the insertion hole set on the size adjustment plate 52. At this time, the size adjustment plate 52 is released from the fixed mode, and the size adjustment plate 52 can be telescopically adjusted on the inner wall of the stroke groove 51 set at the bottom of the first positioning pressure plate 48, so as to adjust the size of the antistatic film pressed on the base 1, thereby adjusting the cutting size of the antistatic film. After long-term use of the quick-setting component 4, the first positioning pressure plate 48, the second positioning pressure plate 49 and the friction strip 411 installed in the installation groove 410 at the bottom of the size adjustment plate 52 will be worn, which will greatly reduce the positioning effect.
