[0037] Currently, films are frequently used in the packaging industry and in daily life. The film manufacturing process requires a feeding mechanism and a cutting mechanism, so that the feeding mechanism can transport the film to the cutting mechanism for trimming.

[0038] Because the film is relatively loose during transport, existing feeding mechanisms are equipped with tension rollers to tighten the film. However, most existing tension rollers are fixed to the frame, making it difficult to adjust their position and angle. This often results in incorrect installation of the tension rollers or insufficient clamping force, leading to a loose film and affecting the efficiency of film transport.

[0039] This utility model proposes a film material 70 cutting and feeding device 100. Please refer to [link / reference]. Figures 1 to 4 In one embodiment of the present invention, the film material 70 cutting and feeding device 100 proposed by the present invention includes a fixed frame 10, a discharge roller 20, a tensioning mechanism 40 and a film cutting mechanism 50. The discharge roller 20 stores the film material 70. The discharge roller 20, the tensioning mechanism 40 and the film cutting mechanism 50 are arranged sequentially on the fixed frame 10 along the conveying direction of the film material 70.

[0040] The tensioning mechanism 40 includes a limiting frame 41, a transmission roller 42, and an adjusting pressure roller assembly 43. The limiting frame 41 is mounted on the fixed frame 10, the transmission roller 42 is rotatably mounted on the limiting frame 41, and the adjusting pressure roller assembly 43 is movably mounted on the limiting frame 41 and is located above the transmission roller 42.

[0041] The adjusting pressure roller assembly 43 includes an adjusting component 44 and a pressure roller component 45. The adjusting component 44 is mounted on the limiting frame 41 and extends and retracts relative to the limiting frame 41. The pressure roller component 45 is connected to the adjusting component 44. The adjusting component 44 extends and retracts relative to the limiting frame 41 to drive the pressure roller component 45 to press down or rise, thereby adjusting the position of the pressure roller component 45.

[0042] In one embodiment, the discharge roller 20 holds the film material 70. The film material 70 is transferred from the discharge roller 20 to the tensioning mechanism 40, and then to the film cutting mechanism 50, which cuts the film material 70.

[0043] To increase the clamping force of the tensioning mechanism 40 on the membrane material 70, the adjusting component 44 can extend relative to the limiting frame 41 to drive the pressure roller component 45 downward, thereby reducing the distance between the pressure roller component 45 and the transfer roller 42. The clamping force of the pressure roller component 45 on the membrane material 70 increases, and the membrane material 70 is pressed tightly on the transfer roller 42, thereby improving the transport efficiency of the membrane material 70 on the transfer roller 42.

[0044] To reduce the clamping force of the tensioning mechanism 40 on the membrane material 70, the adjusting component 44 can be retracted relative to the limiting frame 41 to drive the pressure roller component 45 to rise, thereby increasing the distance between the pressure roller component 45 and the transmission roller 42 and reducing the clamping force of the pressure roller component 45 on the membrane material 70.

[0045] The technical solution of this utility model involves setting a tensioning mechanism 40, and sequentially arranging the discharge roller 20, the tensioning mechanism 40, and the film cutting mechanism 50 on the fixed frame 10 along the conveying direction of the film 70. The tensioning mechanism 40 includes a limiting frame 41, a transmission roller 42, and an adjusting pressure roller assembly 43. The limiting frame 41 is installed on the fixed frame 10, the transmission roller 42 is rotatably installed on the limiting frame 41, and the adjusting pressure roller assembly 43 is movably installed on the limiting frame 41 and located above the transmission roller 42. The adjusting pressure roller assembly 43 includes an adjusting component 44 and a pressure roller component 45. The pressure roller component 45 is connected to the adjusting component 44. The adjusting component 44 is installed on the limiting frame 41 and extends relative to the transmission roller 42 to drive the pressure roller component 45 to press down. The pressure of the pressure roller component 45 on the transmission roller 42 is adjusted to ensure that the pressure roller component 45 has a large clamping force and that the conveying efficiency of the film 70 on the transmission roller 42 is also guaranteed.

[0046] In one embodiment, please refer to Figure 3 and Figure 4The adjusting component 44 also includes a positioning plate 441, a rod 442, and a rotating handle 443. The positioning plate 441 is installed at an angle on the limiting frame 41. One end of the rod 442 is connected to the rotating handle 443, and the other end of the rod 442 is connected to the positioning plate 441 and extends toward the pressure roller component 45 to connect with the pressure roller component 45. When the rotating handle 443 is rotated, the rod 442 extends and retracts relative to the positioning plate 441 to drive the pressure roller component 45 to press down or rise.

[0047] The positioning plate 441 is used to limit the direction of extension and retraction of the rod 442. The rotating handle 443 is used to drive the rod 442 to rotate and extend and retract relative to the positioning plate 441. Since the end of the rod 442 away from the rotating handle 443 is connected to the pressure roller component 45, when the rotating handle 443 is rotated, the rod 442 can extend and retract relative to the positioning plate 441, thereby driving the pressure roller component 45 to press down or rise, thus adjusting the distance between the pressure roller component 45 and the transfer roller 42, and adjusting the pressing force of the pressure roller component 45 on the film material 70.

[0048] In one embodiment, to drive the transfer roller 42 to rotate so that the film 70 is conveyed on the transfer roller 42 to the film cutting mechanism 50, please refer to... Figure 1 and Figure 2 The film material 70 cutting and feeding device 100 also includes a first drive assembly 81, multiple transmission rollers 82 and a synchronous belt 83. The first drive assembly 81 is mounted on the fixed frame 10, and the multiple transmission rollers 82 are rotatably mounted on the fixed frame 10. Two of the transmission rollers 82 are respectively connected to the first drive assembly 81 and the transmission roller 42. The synchronous belt 83 connects the multiple transmission rollers 82. The first drive assembly 81 is used to drive the multiple transmission rollers 82 to rotate, thereby driving the transmission roller 42 to rotate.

[0049] Multiple transmission rollers 82 are located on the side of the fixing frame 10 opposite to the tensioning mechanism 40, to make efficient use of the space in the fixing frame 10. The first drive assembly 81 is a motor. (See also...) Figure 2 The first drive assembly 81 is used to drive one of the transmission wheels 82 to rotate, and drives the transmission wheel 82 connected to the transmission roller 42 to rotate via the synchronous belt 83, thereby driving the transmission roller 42 to rotate.

[0050] Further, please refer to Figure 3In one embodiment, the pressure roller component 45 includes a first pressure roller 451, a second pressure roller 452, a third pressure roller 453, and a connecting frame 454. The connecting frame 454 is located above the transfer roller 42. The first pressure roller 451, the second pressure roller 452, and the third pressure roller 453 are rotatably mounted on the connecting frame 454, with the second pressure roller 452 located between the first pressure roller 451 and the second pressure roller 452. A rod 442 is connected to the first pressure roller 451. The first pressure roller 451, the second pressure roller 452, and the third pressure roller 453 can all press the film material 70 on the transfer roller 42 to increase the contact area between the pressure roller component 45 and the film material 70. The rod 442 is connected to the first pressure roller 451. The pressure roller assembly 45 is provided with a connecting frame 454, which connects the first pressure roller 451, the second pressure roller 452, and the third pressure roller 453 to each other, so that when the rod 442 extends or retracts, the first pressure roller 451, the second pressure roller 452, and the third pressure roller 453 can all be driven to rise and fall. Optionally, the diameter of the third pressure roller 453 can be larger than the diameter of the first pressure roller 451, so that the film material 70 of the transfer roller 42 can be pressed by the third pressure roller 453.

[0051] To facilitate the cutting of the film material 70, the film cutting mechanism 50 includes a material support platform 51 and a cutting assembly 52. ​​The material support platform 51 is located on the fixed frame 10 and is positioned on one side of the tensioning mechanism 40. The discharge roller 20, the tensioning mechanism 40, and the material support platform 51 are arranged sequentially along the conveying direction of the film material 70. The cutting assembly 52 is located above the material support platform 51 and can be raised and lowered relative to the material support platform 51. The film material 70 is conveyed to the material support platform 51, and the cutting assembly 52 is used to cut the film material 70.

[0052] The cutting assembly 52 includes a pressing assembly 53, a film cutting assembly 54, and a mounting frame 55. The mounting frame 55 is installed on the fixed frame 10 and is located above the material support platform 51. The film cutting assembly 54 and the pressing assembly 53 are located on both sides of the mounting frame 55. Both the pressing assembly 53 and the film cutting assembly 54 can be raised and lowered relative to the material support platform 51. The pressing assembly 53 is used to press against the film material 70 on the material support platform 51, and the film cutting assembly 54 is used to cut the film material 70 on the material support platform 51.

[0053] To make efficient use of the space in the mounting frame 55, the pressing assembly 53 and the film cutting assembly 54 are respectively arranged on both sides of the mounting frame 55. The pressing assembly 53 can press down relative to the mounting frame 55 so as to press the film material 70 onto the material support platform 51, thereby facilitating the film cutting assembly 54 to cut the film material 70 on the material support platform 51.

[0054] Specifically, please refer to Figure 6The pressing assembly 53 includes a second drive assembly 530 and a pressure plate 531. The second drive assembly 530 is mounted on the mounting frame 55 and connected to the pressure plate 531 to drive the pressure plate 531 to descend and press against the film material 70 on the material support platform 51. In one embodiment, the second drive assembly 530 is a cylinder. The second drive assembly 530 is used to drive the pressure plate 531 to press down, so that the pressure plate 531 presses the film material 70 onto the material support platform 51.

[0055] For easier cutting and trimming of the membrane material 70, please refer to [link / reference]. Figure 5 The film cutting assembly 54 includes a third drive assembly, a traversing component 541, and a cutting blade 545. The third drive assembly and the traversing component 541 are mounted on the mounting frame 55. The cutting blade 545 is connected to the traversing component 541. The third drive assembly is used to drive the traversing component 541 and the cutting blade 545 to move along the length direction of the mounting frame 55.

[0056] In one embodiment, the third drive component is a cylinder. The third drive component is used to drive the cutting blade 545 to move in the width direction of the material support platform 51.

[0057] In one embodiment, the lateral movement component 541 includes a lead screw 542, a movable seat 543, and two positioning blocks 544. The two positioning blocks 544 are located on opposite sides of the mounting bracket 55. The lead screw 542 is rotatably mounted on the two positioning blocks 544.

Please refer to [link / reference]. Figure 5 The cutting blade 545 is installed at the bottom of the movable seat 543. The cutting blade 545 can be driven by the movable seat 543 to move along the width direction of the material support platform 51, thereby cutting the membrane material 70.

[0058] Because the surface of the membrane material 70 is prone to static electricity, applying the static-laden membrane material 70 to components can easily damage them. Therefore, it is necessary to remove static electricity from the membrane material 70. The membrane material 70 cutting and feeding device 100 of this invention also includes an antistatic ion bar 60. A gap exists between the tensioning mechanism 40 and the material support platform 51. The antistatic ion bar 60 is mounted on the fixing frame 10 and located below the material support platform 51, with its air outlet facing the gap. In one embodiment, the air outlet of the antistatic ion bar 60 blows out negative ions to remove static electricity from the membrane material 70, thereby preventing the surface of the membrane material 70 from becoming statically charged.

[0059] The static ion bar 60 can be any existing static ion bar 60, and this utility model does not limit the structure of the static ion bar 60.
