[0007] Furthermore, the adjustment part includes an adjustment component disposed on the front side of the housing; and a pushing component located inside the housing; wherein the rear side of the adjustment component extends into the housing, and the pushing component is located below the adjustment component.
[0008] Furthermore, the locking part includes a limiting component mounted on the front side of the housing; and an unlocking component disposed at the front of the housing; wherein the unlocking component is located in front of the limiting component.
[0009] Furthermore, the adjusting assembly includes a slider one slidably connected to the inner wall of the outer shell, a slider two slidably connected to the inner wall of the outer shell, two elastic elements disposed inside the outer shell, and three rollers disposed on the outer shell; wherein, the outer wall of the upper roller is rotatably connected to slider two, and the outer walls of the two lower rollers are rotatably connected to the outer shell; the elastic element includes a limiting rod fixedly connected to the inner wall of the outer shell, and a spring is sleeved on the outer wall of the limiting rod; wherein, the limiting rod passes through slider one, and the outer wall of the limiting rod is slidably connected to slider one, while the limiting rod passes through slider two, and the outer wall of the limiting rod is slidably connected to slider two; the top of the spring is fixedly connected to slider two, and the bottom of the spring is fixedly connected to slider one.
[0010] Furthermore, the pushing component includes a rotating shaft rotatably connected to the inner wall of the housing, a gear fixedly connected to the outer wall of the rotating shaft, a rack slidably connected to the inner wall of the housing, and the top of the rack fixedly connected to a slider; wherein, the gear meshes with the rack, the rotating shaft passes through the gear, the front side of the rotating shaft extends to the outside of the housing, rotating the rotating shaft will drive the gear to rotate, thereby driving the rack to move.
[0011] Furthermore, the limiting component includes a first ring fixedly connected to the outer wall of the rotating shaft, and a second ring fixedly connected to the front side of the outer shell; wherein the rotating shaft passes through the first ring, and the second ring is located outside the first ring. When the first ring is unlocked, the rotating shaft can be rotated, and when the first ring is locked, the rotating shaft cannot be rotated.
[0012] Furthermore, the unlocking component includes a rotating block rotatably connected to the front side of the second ring, a limiting block fixedly connected to the rear side of the rotating block, and a sliding member provided inside the second ring; wherein, the rotating block is rotatably connected to the second ring coaxially, and the sliding member includes a locking block slidably connected to the inner wall of the second ring, and a limiting groove is formed on the front side of the locking block; wherein, the shape of the limiting block is adapted to the limiting groove, and the locking block is adapted to the first ring, and by rotating the rotating block, the limiting block can be driven to slide, thereby driving the locking block to slide.
[0013] This utility model has the following beneficial effects:
[0014] 1. By setting an adjustment unit, when printing is required, the printing material passes sequentially through the bottom of the right roller, the top of the middle roller, and the bottom of the left roller, causing the material to slide down the second slider. At this time, the spring is compressed and generates elastic force under the action of the limit rod. When the material tension decreases, the spring force is released. At this time, the middle roller is moved upward through the second slider, thereby buffering the increased tension. When the material tension increases, the spring is further compressed through the second slider, generating elastic force, thereby buffering the tension. When it is necessary to adjust the tension adjustment range, the gear is rotated through the locking unit and the rotating shaft, thereby moving the rack upward and moving the first slider upward, compressing the spring and generating elastic force, thereby changing the spring's elastic coefficient and completing the adjustment of the tension adjustment range. The device can control the range of printing bottom tension adjustment, adapting it to the dynamic tension adjustment range required by different materials. It can be directly changed when changing materials, thereby reducing downtime and improving work efficiency.
[0015] 2. By setting a locking part, when the locking part is operated, the rotating block can be rotated to make it rotate on the second ring. When the rotating block rotates, it will drive the limiting block to rotate. At this time, under the action of the limiting groove, the locking block will be driven to slide in the second ring and move away from the first ring. At this time, the rotating shaft can be rotated to drive the first ring to rotate. After the rotation is completed, the rotating block can be rotated in the opposite direction, so that under the action of the limiting groove, the locking block will be driven to slide through the limiting block, so that the bottom end of the locking block is locked into the limiting groove of the first ring, thereby locking the first ring and completing the limiting. After the adjustment is completed, the rotating shaft can be locked to prevent it from rotating during use, which would cause unnecessary changes in the tension adjustment range, thus ensuring the stable operation of the device.

[0031] A specific application of this embodiment is as follows: During use, when printing is required, the printing material passes sequentially through the bottom of the right roller 215, the top of the middle roller 215, and the bottom of the left roller 215, causing the material to slide down the second slider 212. At this time, the spring 214 is compressed and generates elastic force under the action of the limiting rod 213. When the material tension decreases, the elastic force of the spring 214 is released. This causes the middle roller 215 to move upward via the second slider 212, thus buffering the increased tension. Conversely, when the material tension increases, the spring 214 is further compressed via the second slider 212, generating elastic force, thus buffering the tension. When the tension adjustment range needs to be adjusted, the gear 222 can be rotated via the locking part 3 and the rotating shaft 221, thereby causing the rack 223 to move upward. This causes the slider 211 to move upward, compressing the spring 214 and generating elastic force, thereby changing the elastic coefficient of the spring 214 and adjusting the tension range. When the locking part 3 is operated, the rotating block 321 can be rotated to rotate on the ring 312. When the rotating block 321 rotates, it will drive the limiting block 322 to rotate. At this time, under the action of the limiting groove 324, the locking block 323 will slide in the ring 312 and move away from the ring 311. At this time, the rotating shaft 221 can be rotated to drive the ring 311 to rotate. After the rotation is completed, the rotating block 321 can be rotated in the opposite direction, so that under the action of the limiting groove 324, the locking block 322 drives the locking block 323 to slide, so that the bottom end of the locking block 323 is locked into the limiting groove of the ring 311, thereby locking the ring 311 and completing the limiting.
