[0048] like Figure 4 - Figure 5 As shown, the film guiding mechanism 2 includes a winding roller 21, a mounting frame 22, a guiding assembly 23, and an adjusting assembly. The winding wheel is fixedly arranged at the bottom of the machine body frame 1, and the film is transmitted to the next process through the winding roller 21.

[0049] The guide assembly 23 includes a first guide member 231 and a second guide member 232. The first guide member 231 is installed on the side of the mounting frame 22 close to the roller 21. The two ends of the first guide member 231 have a height difference. The second guide member 232 is arranged at the end of the first guide member 231 away from the roller 21. The two ends of the second guide member 232 have a height difference, and the inclination directions of the first guide member 231 and the second guide member 232 are opposite. When the film passes through the bottom of the first guide member 231 and is located between the first guide member 231 and the second guide member 232, the end of the second guide member 232 close to the first guide member 231 lifts up the middle position of the film to fold the middle position of the film inward to form the bottom of the packaging bag.

[0050] The first guide member 231 includes a guide plate 2311 and a guide strip 2312. The guide plate 2311 is arranged in a triangular shape. The top corner of the guide plate 2311 is arranged away from one end of the roller 21. The guide strip 2312 is detachably fixed to the bottom of the adjustment plate. The guide strip 2312 protrudes from the side of the adjustment plate. The cross-section of the guide plate 2311 is arranged in a rectangular shape. The degree to which the guide strip 2312 protrudes from the side of the adjustment plate can be adjusted to achieve flexible control of the bottom width of the packaging bag. The more protruding the guide strip 2312 is, the greater the width of the bottom of the manufactured packaging bag is.

[0051] In order to adjust the protrusion degree of the guide bar 2312, in this embodiment, an adjustment groove 2312a is opened on the guide bar 2312, and the bolt passes through the adjustment groove 2312a and is fixedly connected to the guide bar 2312. The bolt can reciprocate along the adjustment groove 2312a, and the guide bar 2312 is driven to translate by the bolt, and the protrusion displacement of the guide bar 2312 is fixed by tightening the bolt.

[0052] The adjustment assembly includes a height adjustment member 241, an angle adjustment member 242, and a translation adjustment member 243. The height adjustment member 241 includes a screw rod 2411, a hand wheel 2412, a guide member 2413, and a fixed plate 2414. One end of the screw rod is fixedly connected to the hand wheel 2412, and the other end passes through the fixed plate 2414 and the mounting frame 22 in sequence and is hinged to the top of the adjustment plate of the first guide member 231. The guide member 2413 includes a first guide rod 241a and a second guide rod 241b. One end of the first guide rod 241a is fixedly connected to the fixed plate 2414, and the other end is connected to the first guide member 231. A guide member 231 is fixedly connected, one end of the second guide member 232 is fixedly connected to the fixed plate 2414, and the other end is fixedly connected to the second guide member 232. The hand wheel 2412 is rotated to drive the screw rod 2411 to rotate. The rotation of the screw rod 2411 drives the first guide member 231 and the second guide member 232 to rise or fall at the same time, changing the distance between the guide member 2413 and the body base 1, which is suitable for packaging of different widths. The vertical height between the guide assembly 23 and the roller 21 is adjusted by the height adjustment member 241 to guide packaging of different specifications.

[0053] In order to better adjust the concave depth of the bottom of the packaging bag, in this embodiment, the second guide member 232 is slidably connected to the second guide rod 241b, and a limiting member is arranged between the second guide member 232 and the second guide rod 241b. The limiting member can position the second guide member 232 on the second guide rod 241b. The limiting member uses a bolt that passes through the second guide member 232. By tightening the bolt, the end of the bolt away from the nut is in contact with the second guide rod 241b for positioning.

[0054] The angle adjustment member 242 includes a first angle adjustment member 2421 and a second angle adjustment member 2422. The first angle adjustment member 2421 includes a hydraulic rod, one end of the hydraulic rod is hinged to the fixed plate 2414, and the other end is hinged to the end of the first guide member 231 close to the roller 21. The second angle adjustment member 2422 is arranged on the second guide member 232, and is used to adjust the height difference between the two ends of the second guide member 232. By adjusting the telescopic amount of the hydraulic rod in the first angle adjustment member 2421, the inclination degree of the first guide member 231 is changed. The second angle adjustment member 2422 adjusts the inclination degree of the second guide member 232 to achieve flexible control of the inward folding depth of the bottom of the packaging bag. In this embodiment, the second angle adjustment can adopt a hydraulic rod. By adjusting the telescopic amount of the hydraulic rod, the inclination degree of the second guide member 232 is controlled. The angle adjustment member 242 is arranged on the guide assembly 23 to achieve flexible control of the bottom area of ​​the packaging bag and the inward concave depth of the bottom of the packaging bag.

[0055] The translation adjustment member 243 includes a lead screw 2431 and a fixed block 2432. The fixed block 2432 is fixedly arranged at the bottom of the mounting frame 22. One end of the lead screw 2431 is threadedly connected to the fixed block 2432, and the other end is rotatably connected to the body base 1. The lead screw 2431 drives the body base 1 to translate. The translation adjustment member 243 is arranged between the mounting frame 22 and the body base 1 to realize the control of the horizontal position of the roller 21, and the setting height of the two sides of the packaging bag can be flexibly controlled.

[0056] like Figure 6 - Figure 8 As shown, in this embodiment, the edge sealing mechanism 3 includes a longitudinal sealing and pressing mechanism 31 and a longitudinal sealing and pressing automatic adjustment system 32. The longitudinal sealing and pressing mechanism 31 is installed on the machine body frame 1, and the longitudinal sealing and pressing automatic adjustment system 32 adjusts the distance between adjacent longitudinal sealing and pressing mechanisms 31.

[0057] The longitudinal sealing and pressing mechanism 31 includes a first longitudinal sealing plate 311, a second longitudinal sealing plate 312, and a guide rod 313. The first longitudinal sealing plate 311 and the second longitudinal sealing plate 312 are symmetrically arranged. One end of the guide rod 313 is fixedly connected to the first longitudinal sealing plate 311, and the other end is arranged to penetrate the second longitudinal sealing plate 312, and the second longitudinal sealing plate 312 can reciprocate along the axial direction of the guide rod 313.

[0058] The guide rod 313 includes a first guide rod 3131 and a second guide rod 3132. The first guide rod 313 and the second guide rod 3132 are arranged in parallel. The first guide rod 3131 is located at the top of the first longitudinal sealing plate 311, and the second guide rod 3132 is located at the bottom of the first longitudinal sealing plate 311. A connecting plate 3a is fixedly provided at one end of the guide rod 313 away from the first longitudinal sealing plate 311. Both ends of the connecting plate 3a are fixedly connected to the adjacent sides of the first guide rod 3131 and the second guide rod 3132 respectively. A transmission assembly 34 is arranged between the connecting plate 3a and the second longitudinal sealing plate 312.

[0059] The transmission assembly 34 includes a first connecting block 341, a second connecting block 342, and a driving connecting pendulum block 343. The driving connecting pendulum block 343 is rotatably arranged on the machine body base frame 1. One end of the first connecting block 341 is rotatably connected to one end of the driving connecting pendulum block 343, and the other end is rotatably connected to the connecting plate 3a. One end of the second connecting block 342 is rotatably connected to the other end of the driving connecting pendulum block 343, and the other end is rotatably connected to the second longitudinal sealing plate 312. One end of the driving connecting pendulum block 343 close to the connecting plate 3a is protruded to form a driving part 33a. The driving part 33a is rotatably arranged with a driving rod 33b. The driving rod 33b The longitudinal movement drives the connecting pendulum block 343 to rotate, and the connecting pendulum block 343 drives the first connecting block 341 and the second connecting block 342 to make relative movement. When the first connecting block 341 and the second connecting block 342 move, they drive the connecting rod and the second longitudinal sealing plate 312 to move. The movement of the connecting rod drives the first longitudinal sealing plate 311 to move through the guide rod 313, so that the distance between the first longitudinal sealing plate 311 and the second longitudinal sealing plate 312 changes. Through the transmission assembly 34, the first longitudinal sealing plate 311 and the second longitudinal sealing plate 312 make synchronous relative movement, which can make the force surface of the longitudinal cover of the packaging bag more uniform.

[0060] In order to avoid excessive pressure between the longitudinal sealing plates when the driving connection pendulum block 343 drives the longitudinal sealing plates to move relative to each other, thereby preventing the packaging bag located between the two longitudinal sealing plates from being subjected to excessive force, causing excessive heat sealing of the edge, reducing the thickness of the edge, lowering the overall structure of the edge, and affecting the overall strength of the packaging bag, in this embodiment, a buffer assembly 35 is rotatably provided at one end of the driving connection pendulum block 343 away from the connecting plate 3a, and the buffer assembly 35 includes a buffer spring 351 and a telescopic rod 352, one end of the telescopic rod 352 is rotatably connected to the driving connection pendulum block 343, and the other end is rotatably connected to the driving rod 33b, the buffer spring 351 is sleeved on the telescopic rod 352, and the two ends of the buffer spring 351 are fixedly connected to the two ends of the telescopic rod 352, through the reaction force of the spring, a flexible force is provided between the two longitudinal sealing plates, and the pressure on the side of the packaging bag by the two longitudinal sealing plates can be adjusted automatically, thereby avoiding excessive heat sealing of the edge, reducing the thickness of the edge, lowering the overall structure of the edge, and affecting the overall strength of the packaging bag.

[0061] The side of the packaging bag has uneven cutting edges when it is cut. In order to make the side of the packaging bag be subjected to more uniform force when the side is longitudinally sealed between the first longitudinal sealing plate 311 and the second longitudinal sealing plate 312, a buffer layer is fixedly provided on the side of the second longitudinal sealing plate 312 close to the first longitudinal sealing plate 311. In order to better play a buffering role, in this embodiment, the buffer layer adopts a high-temperature resistant silicone buffer layer. When the first longitudinal sealing plate 311 is used to squeeze the second longitudinal sealing plate 312, the silicone buffer layer can well buffer the side of the packaging bag, so that the upper and lower ends of the side of the packaging bag are subjected to force at the same time when the side is longitudinally sealed, thereby avoiding the loose sealing of the side of the packaging bag due to uneven force, thereby reducing the sealing quality of the packaging bag.

[0062] In order to perform the heat sealing process on both sides of the packaging bag at the same time, in this embodiment, there are at least two longitudinal sealing and pressing mechanisms 31. In order to perform the heat sealing process on more packaging bags at the same time, the longitudinal sealing and pressing mechanisms 31 are grouped into two, and multiple groups can be set to perform the heat sealing process at the same time.

[0063] The automatic adjustment system 32 for longitudinal sealing and pressing includes a lead screw 321, a driving motor 322, a locking cylinder 323, a first fixed block 324, and a second fixed block 325. The first fixed block 324 and the second fixed block 325 are respectively fixedly arranged on both sides of the machine body frame 1, and the first fixed block 324 and the second fixed block 325 are coaxially arranged.

One end of the lead screw 321 is rotatably connected to the first fixed block 324, and the other end is rotatably connected to the second fixed block 325, and is arranged through the second fixed block 325.

[0064] The driving motor 322 is fixedly arranged on the machine body base frame 1, and the rotating shaft of the driving motor 322 is fixedly connected to one end of the lead screw 321 close to the second fixed block 325, the locking cylinder 323 is fixedly arranged on the top of the longitudinal sealing pressing mechanism 31, the lead screw 321 runs through the top of the longitudinal sealing pressing mechanism 31, the locking cylinder 323 is telescopically controlled, and the telescopic rod 352 of the locking cylinder 323 is engaged with the lead screw 321, the driving motor 322 drives the lead screw 321 to rotate, and the locking cylinder 323 is telescopically controlled to lock the locking cylinder 323. The telescopic rod 352 of the cylinder 323 is engaged with the screw 321. When the locking cylinder 323 is engaged with the screw 321, the screw 321 rotates and drives the locking cylinder 323 to move upward along the axis of the screw 321. The locking cylinder 323 drives the longitudinal sealing and pressing mechanism 31 to move upward along the axis of the screw 321, thereby limiting the position of the longitudinal sealing and pressing mechanism 31 and controlling the locking cylinders 323 of different longitudinal sealing and pressing mechanisms 31. The distance between the longitudinal sealing and pressing mechanisms 31 can be flexibly controlled to adapt to packaging bags of different specifications.

[0065] In order to calibrate the distance when adjusting the distance between the longitudinal sealing and pressing mechanisms 31, in the present embodiment, a ruler 36 is fixedly provided at the bottom of the machine body frame 1, a standard scale is provided on the ruler 36, and the ruler 36 is provided parallel to the lead screw 321. Through the scale on the ruler 36, the distance between the longitudinal sealing and pressing mechanisms 31 can be intuitively calibrated, and the longitudinal sealing and pressing mechanisms 31 can be positioned more accurately.

[0066] In this embodiment, in order to better fully automate the distance between the longitudinal sealing and pressing mechanisms 31, an identification device is provided on the scale 36, and the real-time distance between adjacent longitudinal sealing devices is sent to an external central processing device through the identification device. The central processing device then compares the distance with the input bag size and issues different commands to control the rotation of the drive motor 322 and the extension and retraction of the locking cylinder 323, thereby realizing the movement of different longitudinal sealing and pressing mechanisms 31 and achieving fully automatic adjustment, saving time and effort.

[0067] In order to more accurately define the distance between the longitudinal sealing and pressing mechanisms 31 , the thread pitch on the lead screw 321 is set to a small range. The smaller the pitch, the higher the accuracy.

On the one hand, the sliding assembly 37 enables the longitudinal sealing and pressing mechanism 31 to translate along the slide rail 371, and on the other hand, it avoids the friction between the screw 321 and the locking cylinder 323 when the screw 321 drives the longitudinal sealing and pressing mechanism 31 to translate, causing the longitudinal sealing and pressing mechanism 31 to rotate along the screw 321, thereby affecting the positioning of the longitudinal sealing and pressing mechanism 31.

[0069] In order to better fix the longitudinal sealing mechanism and adapt to the long-distance arrangement of the longitudinal sealing mechanism on the machine body base frame 1 , in this embodiment, the number of the sliding assembly 37 is at least one, and the plurality of sliding assemblies 37 are arranged in parallel along the height direction of the machine body base frame 1 .
