[0004] However, the device still has the following drawbacks:

[0005] When this device is in use, multiple material rollers rotate and two sealing and cutting devices cut. There are no protective devices on the outside of the device. If personnel accidentally enter the vicinity of the device, it is easy to cause injury to the operator. Therefore, we need to propose a self-protecting four-side sealing automatic packaging machine. Utility Model Content

[0006] The purpose of this utility model is to provide a self-protecting four-side sealing automatic packaging machine. A fixing block is used to install a mounting frame, and the mounting frame is used to install a safety light curtain. Two corresponding safety light curtains work together to surround the outside of the device. When a person accidentally enters the light curtain, the light curtain transmits a signal to the controller, which then stops the device to prevent damage to the person. At the same time, a limit rod is used to fix the mounting frame. By pulling out the limit rod, it is easy to install and remove the mounting frame. When the limit rod is pulled out, it drives the limit ring to move, and the limit ring compresses the spring. When the limit rod is released, under the elastic force of the spring, the limit rod inserts into the interior of the mounting frame to limit the mounting frame, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A self-protecting four-side sealing automatic packaging machine includes a base plate, and multiple protective components are arranged in an array on the upper end of the base plate;

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A self-protecting four-side sealing automatic packaging machine includes a base plate 1, and multiple protective components 2 arranged in an array are provided on the upper end of the base plate 1;

[0026] Multiple protective components 2 are fixedly installed on the fixing blocks 21 at the upper end of the base plate 1. The mounting brackets 22 are slidably connected inside the multiple fixing blocks 21. The mounting brackets 22 are in contact with the base plate 1. Two safety light curtains 23 are evenly distributed at the upper end of the multiple mounting brackets 22. The two safety light curtains 23 are correspondingly arranged. The mounting brackets 22 are slidably connected to the inside of the mounting brackets 22. The limiting rods 24 are slidably connected to the fixing blocks 21. A spring 25 is sleeved on the outside of the limiting rods 24. A limiting ring 26 is fixedly connected to the outside of the limiting rods 24. The limiting ring 26 is slidably connected to the fixing blocks 21.

[0027] A worktable 3 is provided at the upper end of the base plate 1. Multiple fixed frames 4 are fixedly connected to the side wall of the worktable 3. Upper feeding rollers 5 are provided inside the two corresponding fixed frames 4. Two limiting rollers 6 are provided at the upper end of the worktable 3. Upper receiving rollers 7 are provided inside the two corresponding fixed frames 4. Lower feeding rollers 12 are provided inside the two corresponding fixed frames 4. Lower receiving rollers 13 are provided inside the two corresponding fixed frames 4. A drive motor for driving the upper receiving rollers 7 and lower receiving rollers 13 is provided on the side wall of one of the fixed frames 4.

[0028] For example, two drive motors drive the upper take-up roller 7 and the lower take-up roller 13 to rotate respectively. The upper take-up roller 7 and the lower take-up roller 13 drive the upper and lower film strips to move. The upper take-up roller 7 and the lower feed roller 12 rotate accordingly. The limiting roller 6 limits the upper film strip.

[0029] A cutting assembly 8 for sealing and cutting workpieces of different widths is provided on the side wall of the worktable 3. The cutting assembly 8 includes two first telescopic rods 81 fixedly installed on the side wall of the worktable 3. The output ends of the two first telescopic rods 81 are provided with a rotating rod 82 through a mounting block. A drive motor for driving the rotating rod 82 is provided on the side wall of the mounting block. Multiple symmetrically distributed limiting holes 83 are opened inside the rotating rod 82. Limiting bolts 84 are threaded inside the limiting holes 83. A mounting shell 85 is rotatably connected to the outside of the limiting bolts 84. The mounting shell 85 is in contact with the rotating rod 82. A cutting blade 86 is fixedly connected to the side wall of the mounting shell 85. A sealing ring 87 is fixedly connected to the side wall of the cutting blade 86. The rotating rod 82 is slidably connected to the cutting blade 86 and the sealing ring 87 respectively.

[0030] For example, the first telescopic rod 81 controls the height of the rotating rod 82, and the rotating rod 82 drives the cutting blade 86 and the sealing ring 87 to rise and fall. The sealing ring 87 presses the side of the packaging, and the cutting blade 86 cuts off the excess film. At the same time, the drive motor drives the rotating rod 82 to rotate, which facilitates continuous cutting of the film strip. The limiting bolt 84 fixes the position of the cutting blade 86 and the sealing ring 87 through the mounting shell 85, which facilitates the movement of the cutting blade 86 and the sealing ring 87 to seal the film strip with different widths.

[0031] Two symmetrically distributed second telescopic rods 9 are provided on the side wall of the workbench 3. The output ends of the two second telescopic rods 9 are provided with sealing pressure rollers 10 through mounting blocks. The lower end of the sealing pressure rollers 10 is fixedly connected to a cutting knife 11.

[0032] For example, the second telescopic rod 9 drives the sealing pressure roller 10 to rise and fall, the sealing pressure roller 10 seals the vertical direction of the cutting blade 86, and the cutting blade 11 cuts the sealed position.

[0033] Working principle: In use, two drive motors drive the upper take-up roller 7 and the lower take-up roller 13 to rotate, respectively. The upper take-up roller 7 and the lower take-up roller 13 drive the upper and lower film strips to move, and the upper take-up roller 7 and the lower release roller 12 rotate accordingly. The limiting roller 6 limits the upper film strip. The first telescopic rod 81 controls the height of the rotating rod 82. The rotating rod 82 drives the cutting blade 86 and the sealing ring 87 to rise and fall. The sealing ring 87 presses the side of the packaging tightly, and the cutting blade 86 cuts off the excess film. Simultaneously, the drive motor drives the rotating rod 82 to rotate, facilitating continuous cutting of the film strip. The limiting bolt 84 fixes the position of the cutting blade 86 and the sealing ring 87 through the mounting shell 85, facilitating the movement of the cutting blade 86 and the sealing ring 87 to seal the film strip with different widths. The second telescopic rod 9 drives the sealing roller 10 to rise and fall. The sealing roller 10 seals the vertical direction of the cutting blade 86, and the cutting blade 11 cuts the sealed position. This process is repeated twice to achieve sealing of the packaging strip.

[0034] The fixing block 21 is used to install the mounting frame 22, and the mounting frame 22 is used to install the safety light curtain 23. The two corresponding safety light curtains 23 are used in conjunction, and multiple safety light curtains 23 surround the outside of the device. When personnel accidentally enter the light curtain, the light curtain transmits a signal to the controller, and the controller stops the device to prevent damage to personnel. At the same time, the mounting frame 22 is fixed by the limiting rod 24. By pulling out the limiting rod 24, it is easy to install and remove the mounting frame 22. When the limiting rod 24 is pulled out, the limiting rod 24 drives the limiting ring 26 to move. The limiting ring 26 compresses the spring 25. When the limiting rod 24 is released, under the elastic force of the spring 25, the limiting rod 24 is inserted into the interior of the mounting frame 22 to limit the mounting frame 22.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
