[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A tape slitting machine with convenient blade spacing adjustment comprises a base 1, frames 2 are fixedly installed on both sides of the top of the base 1, a movable frame 3 is movably installed between the two frames 2, and partitions 4 are fixedly installed at both ends of the middle of the movable frame 3; a plurality of knife racks 5 are arranged side by side between the movable frame 3 and the two partitions 4, a cutter 6 is arranged at the bottom ends of the plurality of knife racks 5, and the top ends of the plurality of knife racks 5 are movably connected through a first spring 7; movable blocks 8 are fixedly connected on both sides of the movable frame 3, a second cylinder 9 is arranged at one end of the outer side of the two movable blocks 8, and the output shafts of the two second cylinders 9 pass through the partition 4 and are fixedly installed with push plates 10;

[0026] In this embodiment, when adjusting the spacing of the cutters 6, the second cylinders 9 outside the two movable blocks 8 are started, and the two second cylinders 9 are started to push the push plates 10 forward. The push plates 10 are pushed forward and then control the knife holders 5 at the two sides of the movable frame 3 to move synchronously. After the two knife holders 5 move, the first springs 7 are compressed, and the other end of the first spring 7 pushes the knife holders 5 on one side in turn. By analogy, the spacing of each knife holder 5 can be adjusted to be equal through multiple first springs 7. In this way, when adjusting the spacing of the knife holders 5, there is no need to manually adjust each one individually, and the adjustment can be completed at one time, thereby improving the adjustment speed;

[0027] like Figure 1 and Figure 2 As shown, the top upper surfaces of the two frames 2 are fixedly mounted with first cylinders 11, the output shafts of the two first cylinders 11 pass through the frames 2 and are fixedly connected to the top upper surface of the movable block 8, and a limiting groove 12 is provided between the inner sides of the two frames 2, and the two movable blocks 8 are slidably connected to the two limiting grooves 12 respectively;

[0028] In this embodiment, after the adjustment of the cutter 6 is completed, the tape is transported to the top of the base 1 through the conveying device, and then the first cylinders 11 at the tops of the two frames 2 are controlled to start. After the two first cylinders 11 are started, the movable block 8 is pressed down. When the movable block 8 is pressed down, the two side surfaces thereof will slide down along the inside of the limiting groove 12 until the cutter 6 is attached to the upper surface of the tape for cutting. When the tape needs to be replaced, the cutter 6 is controlled to rise by the first cylinder 11, thereby achieving the purpose of facilitating replacement.

[0029] like Figure 4 As shown, the bottom end of the tool holder 5 is fixedly connected with a clamping seat 13, the top end of the cutter 6 is fixedly connected with a clamping head 14, the clamping head 14 is clamped and fixed with the clamping seat 13, a second spring 15 is arranged on the inner side of the middle part of the tool holder 5, the bottom end of the second spring 15 is fixedly connected with a locking rod 16, the top end of the middle part of the clamping head 14 is provided with a locking hole 17, the bottom end of the locking rod 16 passes through the tool holder 5 and the clamping seat 13 and is sleeved in the locking hole 17, the top end of the locking rod 16 passes through the second spring 15 and is fixedly connected with the tool holder 5 with a dial head 18;

[0030] In this embodiment, after the cutting edge of the cutter 6 is worn, it needs to be disassembled and replaced. When replacing, the pull head 18 is lifted up, and the pull head 18 lifts the locking rod 16 from the locking hole 17, and then pushes the clamping head 14 from the side, and pushes the clamping head 14 out of the side of the clamping seat 13 at the bottom end of the tool holder 5, and then replaces the new cutter 6 and clamps it in. In this way, when replacing the cutter 6, there is no need to remove the screws back and forth, so as to achieve the purpose of quick disassembly and assembly;

[0031] like Figure 3 As shown, guide blocks 19 are fixedly connected to the outer walls of both sides of the tool holder 5, and guide grooves 20 are penetrated and opened on both sides of the movable frame 3, and the guide grooves 20 are slidably connected to the guide blocks 19;

[0032] In this embodiment, when adjusting the spacing of the tool holder 5, the guide blocks 19 at both ends of the tool holder 5 will slide and guide synchronously along the inside of the guide groove 20;

[0033] Working principle: when adjusting the spacing of the cutters 6, start the second cylinders 9 on the outside of the two movable blocks 8, and after the two second cylinders 9 are started, push the push plates 10 forward. After the push plates 10 are pushed forward, the knife racks 5 on both sides of the movable frame 3 are controlled to move synchronously. After the two knife racks 5 move, the first spring 7 is compressed, and the other end of the first spring 7 pushes the knife rack 5 on one side in turn, and so on. The spacing of each knife rack 5 can be adjusted to be equal through multiple first springs 7. When the adjustment of the cutter 6 is completed, the tape is conveyed to the top of the base 1 through the conveying device, and then the first cylinders 11 at the top of the two frames 2 are controlled to start. After the two first cylinders 11 are started, the movable block 8 is pressed down. When the movable block 8 is pressed down, its two side surfaces will slide down along the inside of the limit groove 12 until the cutter 6 is attached to the upper surface of the tape for cutting. When the tape needs to be replaced, the cutter 6 is controlled to rise by the first cylinder 11.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
