Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0027] Addressing the technical problem of existing technologies that struggle to flexibly and precisely adjust the cutting size or method of food storage bags according to actual production needs, this utility model provides a preferred embodiment of a bag-making machine for producing polymer food storage bags, for example... Figure 1-7 As shown: A bag-making machine for producing polymer food preservation bags includes: a workbench 1; a bag-making machine body 2, fixedly connected to the top of the workbench 1; a roll roller 3, rotatably connected to one side of the workbench 1 via a bracket; a cutting part 4 disposed on the top of the workbench 1; an adjustment part 5 disposed inside the cutting part 4; and a bottom leg 6, fixedly connected to the bottom of the workbench 1. The cutting part 4 includes: a fixed rail 411, fixedly connected to the top of the workbench 1, the fixed rails 411 being symmetrically arranged; and a U-shaped sliding frame 415, slidably connected inside the fixed rail 411.

[0028] The top of the fixed rail 411 is rotatably connected to the rotating plate 412 via the base. The top of the fixed rail 411 is provided with a T-shaped groove, which is symmetrically arranged. The interior of the U-shaped sliding frame 415 is provided with a T-shaped opening. One side of the U-shaped sliding frame 415 is provided with a limiting groove, which is symmetrically arranged and connected to the T-shaped opening.

[0029] A knob 413 is rotatably connected to the top of the rotating plate 412. The bottom end of the knob 413 extends downward through the rotating plate 412. A cam 414 is fixedly connected to the bottom end of the knob 413. The cam 414 engages with the T-slot. An electric telescopic column 416 is fixedly connected to the top of the U-shaped sliding frame 415. The telescopic end of the electric telescopic column 416 extends downward through the U-shaped sliding frame 415 and is fixedly connected to a dotted cutting blade 417. A telescopic guide column 418 is provided between the top of the dotted cutting blade 417 and the bottom of the U-shaped sliding frame 415.

[0030] Furthermore, in this embodiment, the U-shaped sliding frame 415 is placed inside the fixed rail 411, and then the rotating plate 412 is controlled to rotate around the axis to block and limit the U-shaped sliding frame 415. Then, the knob 413 is rotated to drive the cam 414 to rotate, thereby achieving the purpose of engaging and fixing the cam 414 with the T-slot. This drives the electric telescopic column 416 to make the point cutting blade 417 slide vertically down along the set trajectory, thereby cutting the material. Example

[0031] Based on Embodiment 1, a preferred embodiment of the bag-making machine for producing polymer food preservation bags provided by this utility model is, for example... Figure 1-7 As shown: Adjustment part 5 includes: a limiting block 511, which is fixedly connected to the bottom of the inner wall of the T-shaped opening, and the limiting blocks 511 are symmetrically arranged; a T-shaped damping block 512, which is slidably connected to the inner wall of the T-shaped opening, and the T-shaped damping blocks 512 are symmetrically arranged; a rectangular slider 514, which is slidably connected to the inner wall of the T-shaped opening; a gear 520, which is rotatably connected to one side of the U-shaped sliding frame 415, and the gears 520 are symmetrically arranged; and a fixing block 522, which is fixedly connected to one side of the U-shaped sliding frame 415, and the fixing blocks 522 are symmetrically arranged.

[0032] A spring 513 is provided between the T-shaped damping block 512 and the limiting block 511. One end of the spring 513 is fixedly connected to one side of the T-shaped damping block 512, and the other end of the spring 513 is fixedly connected to one side of the limiting block 511. A trapezoidal brake block 515 is fixedly connected to the bottom of the rectangular slider 514. The trapezoidal brake block 515 is compatible with the T-shaped damping block 512.

[0033] A brake block 516 is fixedly connected to the top of the rectangular slider 514. The brake block 516 is slidably connected to the limiting groove. A spring 517 is fixedly connected to the top of the brake block 516 and the top of the inner wall of the T-shaped opening. A fixing plate 518 is fixedly connected to the bottom of the brake block 516. A fixing post 519 is fixedly connected between the inner sides of the fixing plate 518.

[0034] A hook 521 is fixedly connected to one side of the gear 520. The hook 521 engages with the fixed post 519. A spring 523 is provided between the hook 521 and the fixed block 522. One end of the spring 523 is fixedly connected to one side of the hook 521, and the other end of the spring 523 is fixedly connected to one side of the fixed block 522. A U-shaped handle 524 is fixedly connected to one side of the hook 521.

[0035] Furthermore, in this embodiment, the U-shaped sliding frame 415 slides along the trajectory of the fixed rail 411. After sliding to a suitable position, the hand-held brake block 516 slides down, thereby causing the trapezoidal brake block 515 to press against the rotating plates 412 on both sides under the transmission of the rectangular slider 514. This causes the T-shaped damping block 512 to slide and press against the inner wall of the fixed rail 411, thus achieving the purpose of fixing the position of the U-shaped sliding frame 415. However, while the brake block 516 slides down, the fixed plate 518 and the fixed column 519 also slide down, thus fixing... The column 519 presses against the hook 521. When the fixed column 519 stops sliding along with the trapezoidal brake block 515, it passes exactly over the top of the hook 521. However, under the action of the spring 513, the hook 521 rotates back to its original position and engages with the fixed column 519 to limit its movement. This achieves the purpose of fixing the position of the brake block 516, thus achieving the purpose of fixing the position of the U-shaped sliding frame 415 simply by pressing. Conversely, pulling the U-shaped handle 524 can control the position movement of the U-shaped sliding frame 415.

[0036] In use, firstly, the U-shaped sliding frame 415 is placed inside the fixed rail 411. Then, the rotating plate 412 is controlled to rotate around the axis to block and limit the U-shaped sliding frame 415. Next, the knob 413 is rotated to drive the cam 414 to rotate, thereby achieving the purpose of engaging and fixing the cam 414 with the T-slot. This drives the electric telescopic column 416, causing the point-cutting blade 417 to slide vertically down along the set trajectory, thereby cutting the material. Secondly, the U-shaped sliding frame 415 is driven to slide along the trajectory of the fixed rail 411. After sliding to the appropriate position, the hand brake block 516 is lowered, thereby causing the trapezoidal brake block 515 to press against the rotating plates 412 on both sides under the transmission of the rectangular slider 514, causing the T-shaped damping block 512 to slide and fix the fixed rail. The inner wall of the rail 411 is squeezed to fix the position of the U-shaped sliding frame 415. However, while the sliding brake block 516 slides down, the fixing plate 518 and the fixing column 519 follow and slide down. The fixing column 519 squeezes the hook 521. When the fixing column 519 stops sliding with the trapezoidal brake block 515, it passes exactly over the top of the hook 521. Under the action of the spring 513, the hook 521 rotates and resets, and engages and limits the fixing column 519, thereby fixing the position of the brake block 516. Thus, the U-shaped sliding frame 415 can be fixed in position by simply pressing. Conversely, pulling the U-shaped handle 524 can control the movement of the U-shaped sliding frame 415.
