Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag making machine technology, and in particular to a bubble wrap bag making machine. Background Technology
[0002] A bubble wrap bag making machine is a specialized piece of equipment that uses polyethylene resin as raw material to produce bubble wrap packaging bags. Its core function is to process polyethylene resin into bubble wrap, and then cut, seal, and print the bubble wrap rolls to finally form packaging bags.
[0003] During the processing of bubble wrap bag making machines, bubble wrap needs to be cut. Existing bubble wrap bag making machines lack a structure to straighten and tighten the bubble wrap during cutting. This makes it difficult for the cutting blade to complete the cutting quickly, and it is also easy for the cut part to stick to the bubble wrap. At the same time, the untightly bubble wrap is also prone to cutting errors, which is not conducive to the cutting process. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a bubble wrap bag making machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bubble wrap bag making machine, comprising:
[0007] A fixed base is provided, on which a fixed bracket is fixedly installed. A telescopic motor is fixedly installed on the fixed bracket. A drive rod is fixedly connected to the output end of the telescopic motor. An mounting plate is fixedly installed on the drive rod. A cutting blade is fixedly snapped onto the mounting plate.
[0008] A straightening structure is provided, comprising a straightening block, and corresponding fixing blocks are fixedly installed on both the straightening block and the mounting plate. A fixing shaft is fixedly connected between the inner walls of the fixing blocks, and a fixing rod is installed between the corresponding fixing shafts. The two ends of the fixing rod are respectively rotatably sleeved on the corresponding mounting plate. An adjustment structure is installed on the mounting plate.
[0009] Preferably, the adjustment structure includes a telescopic rod slidably connected to the side wall of the mounting plate, a sliding block fixedly connected to the side wall of the telescopic rod, a sliding groove matching the sliding block being opened on the mounting plate, a fixing spring fixedly connected between the sliding block and the inner wall of the sliding groove, a rotating block rotatably connected to the side wall of the telescopic rod, and the rotating block being fixedly connected to the side wall of the corresponding fixed rod.
[0010] Preferably, a rubber pad is fixedly wrapped around the outside of the straightening block, and the surface of the rubber pad has friction textures, and a return spring is fixedly installed between the inner walls of the telescopic rod.
[0011] Preferably, the straightening blocks are installed on both sides of the cutting blade, and the straightening blocks on the same side are installed symmetrically in a figure-eight shape.
[0012] Preferably, a torsion spring is fixedly connected to the side wall of the fixing rod, the torsion spring is sleeved on the outside of the fixing shaft, and the torsion spring is fixedly connected to the inner wall of the fixing block.
[0013] Preferably, a conveyor belt is placed on the fixed base, and the position of the conveyor belt corresponds to the cutting blade.
[0014] Compared with the prior art, the beneficial effects of this utility model are: before the cutting blade cuts the bubble wrap, the straightening block is pressed on the bubble wrap, and as the cutting blade moves, the straightening block moves to both sides to straighten and tighten the bubble wrap at the cutting position, so as to facilitate the cutting process and avoid the sticking between the cut-off part and the bubble wrap after the cutting is completed. At the same time, the cutting position of the straightened bubble wrap is less likely to be wrong, which is conducive to the cutting process. Attached Figure Description

Detailed Implementation
[0019] Reference Figures 1-3 A bubble wrap bag making machine, comprising:
[0020] A fixed base 1 is fixedly mounted on the fixed base 1. A fixed bracket 2 is fixedly mounted on the fixed bracket 2. A telescopic motor 3 is fixedly mounted on the fixed bracket 2. A drive rod 4 is fixedly connected to the output end of the telescopic motor 3. An installation plate 5 is fixedly mounted on the drive rod 4. A cutting blade 6 is fixedly snapped onto the installation plate 5. The output end of the telescopic motor 3 drives the drive rod 4 to move up and down, thereby causing the installation plate 5 and the cutting blade 6 to move up and down accordingly. When the cutting blade 6 moves, it will cut the bubble wrap.
[0021] The straightening structure 7 includes a straightening block 9. A corresponding fixing block 10 is fixedly installed on both the straightening block 9 and the mounting plate 5. A fixing shaft 17 is fixedly connected between the inner walls of the fixing blocks 10. A fixing rod 11 is installed between the corresponding fixing shafts 17, and the two ends of the fixing rod 11 are respectively rotatably sleeved on the corresponding 17. An adjustment structure is installed on the mounting plate 5.
[0022] As the mounting plate 5 and the cutting blade 6 move downwards, the straightening block 9 moves downwards accordingly. The straightening block 9 comes into contact with and squeezes the bubble wrap. As the mounting plate 5 continues to move, the fixing rod 11 pushes the straightening block 9 to move to both sides. When the straightening block 9 moves, the friction between it and the bubble wrap will tighten the bubble wrap to facilitate cutting. Finally, the cutting blade 6 comes into contact with the bubble wrap and cuts it.
[0023] The adjustment structure includes a telescopic rod 13 slidably connected to the side wall of the mounting plate 5, a sliding block 14 fixedly connected to the side wall of the telescopic rod 13, a sliding groove 15 matching the sliding block 14 on the mounting plate 5, a fixing spring 16 fixedly connected between the inner wall of the sliding block 14 and the sliding groove 15, and a rotating block 12 rotatably connected to the side wall of the telescopic rod 13, and the rotating block 12 is fixedly connected to the side wall of the corresponding fixed rod 11.
[0024] After the straightening block 9 comes into contact with the bubble wrap, the end of the fixing rod 11 located at the straightening block 9 can no longer move downward. The movement of the mounting plate 5 will cause the upper end of the corresponding fixing rod 11 to move downward, thereby causing the fixing rod 11 to rotate around the rotating block 12 as the axis. At the same time, the rotating block 12 and the telescopic rod 13 will move to ensure that the straightening block 9 always abuts against the bubble wrap when it moves. Moreover, when the telescopic rod 13 moves, it will cause the fixing spring 16 to deform. When the cutting blade 6 moves upward, the elastic force of the fixing spring 16 will cause the telescopic rod 13 to return to its original position.
[0025] The outer side of the straightening block 9 is fixedly wrapped with a rubber pad, and the surface of the rubber pad has friction texture to facilitate the straightening block to straighten the bubble film. A return spring is fixedly installed between the inner walls of the telescopic rod 13 to facilitate the adjustment of the position of the telescopic rod 13 and to limit the position of the straightening block 9.
[0026] The straightening blocks 9 are installed on both sides of the cutting blade 6, and the straightening blocks 9 on the same side are installed symmetrically in a figure-eight shape. Therefore, when the straightening blocks 9 straighten the bubble wrap, the bubble wrap is subjected to more uniform force, avoiding uneven force and bending, which would affect the cutting.
[0027] A torsion spring 18 is fixedly connected to the side wall of the fixed rod 11. The torsion spring 18 is sleeved on the outside of the fixed shaft 17 and is fixedly connected to the inner wall of the fixed block 10. When the straightening block 9 moves, the fixed rod 11 and the fixed shaft 17 will rotate, thereby deforming the torsion spring 18. The elastic force of the torsion spring 18 can facilitate the fixed shaft 17 and the fixed rod 11 to return to their original positions.
[0028] A conveyor belt 8 is placed on the fixed base 1. The position of the conveyor belt 8 corresponds to the cutting blade 6. The conveyor belt 8 is used to transport the bubble wrap and move it to the cutting blade 6 for automatic cutting.
[0029] In this invention, during use, the conveyor belt 8 carries the bubble wrap below the cutting blade 6, while the output of the telescopic motor 3 drives the drive rod 4 to move up and down, causing the mounting plate 5 and the cutting blade 6 to move up and down accordingly. As the cutting blade 6 moves, it cuts the bubble wrap. When the mounting plate 5 and the cutting blade 6 move downwards, the straightening block 9 moves downwards as well, contacting and compressing the bubble wrap. As the mounting plate 5 continues to move, the end of the fixing rod 11 located at the straightening block 9 can no longer move downwards, and the end of the fixing rod 11 located at the mounting plate 5 moves downwards. This causes the fixed rod 11 to rotate around the rotating block 12 as the axis. At the same time, the rotating block 12 and the telescopic rod 13 will move to ensure that the straightening block 9 is always in contact with the bubble wrap when it moves. When the telescopic rod 13 moves, it will cause the fixed spring 16 to deform. When the cutting blade 6 moves upward, the elastic force of the fixed spring 16 will cause the telescopic rod 13 to return to its original position. The fixed rod 11 will push the straightening block 9 to move to both sides. When the straightening block 9 moves, the friction between it and the bubble wrap will tighten the bubble wrap to facilitate cutting. Finally, the cutting blade 6 will contact the bubble wrap and cut it.
