[0032] Reference Figure 1 As shown, this utility model provides a technical solution: a floor covering unfolding and cutting device, comprising:

[0033] Workbench 1, the cross-section of workbench 1 is rectangular;

[0034] Support frame 2 is fixed to the lower surface of worktable 1 and is used to support worktable 1;

[0035] Both sides of the workbench 1 are equipped with scales 5. Personnel use the scales 5 on both sides of the workbench 1 to determine and mark the cutting position, thereby improving the accuracy of floor covering cutting.

[0036] Width adjustment mechanism 3 is located on the upper surface of worktable 1.

[0037] The specific settings and functions of the width adjustment mechanism 3 will be explained below.

[0038] Reference Figures 2 to 4 As shown in this embodiment: the width adjustment mechanism 3 includes two support tripods 301. The lower surfaces of the two support tripods 301 are in contact with the upper surface of the workbench 1. The support tripods 301 are triangular in design and have high stability, so as to stably support the rotating shaft 4 and the bottom leather roll. A lead screw 302 is threaded through the side of each of the two supporting tripods 301. The lead screw 302 has a bidirectional thread on its arc surface. Both ends of the lead screw 302 are rotatably connected to support plates 303. The lower surface of the support plates 303 is fixedly connected to the upper surface of the workbench 1. The upper surfaces of the two supporting tripods 301 are fixedly connected to positioning seats 306. The inner wall of the positioning seats 306 is rotatably connected to positioning cylinders 307. The two positioning cylinders 307 are fitted with rotating shafts 4. By setting a width adjustment mechanism 3, personnel can easily install carpet rolls of different widths onto the cutting device, which facilitates the installation and positioning of carpet rolls of different widths, thereby facilitating the cutting of flooring of different widths and improving the applicability of the flooring unfolding and cutting device. When it is necessary to limit the width of flooring rolls of different widths, the screw 302 is rotated to drive the two support tripods 301 to move towards or away from each other at the same time. The support tripods 301 drive the positioning seats 306, and the positioning seats 306 drive the positioning cylinders 307 until the distance between the two positioning cylinders 307 matches the width of the rotating shaft 4 and the flooring rolls of flooring. Then the rotation of the screw 302 can be stopped.

[0039] Two guide rods 305 are slidably provided on the side of the tripod 301. The guide rods 305 are fixedly connected to the upper surface of the worktable 1. When the lead screw 302 rotates to drive the tripod 301 to move, the guide rods 305 can guide and position the tripod 301, thereby improving the stability of the tripod 301 during movement.

[0040] One of the support plates 303 has a rotating rod 304 rotatably inserted on its side. One end of the rotating rod 304 is fixedly connected to one end of the lead screw 302. Rotating the rotating rod 304 can drive the lead screw 302 to rotate, thus achieving the effect of conveniently controlling the lead screw 302.

[0041] An adjusting ring 308 is threaded onto the outer wall of the positioning cylinder 307. A sliding ring 309 is slidably connected to the outer wall of the positioning cylinder 307. One side of the sliding ring 309 is in contact with the adjusting ring 308. Several top plates 310 are fixedly connected to the side of the sliding ring 309 away from the adjusting ring 308. The cross-section of the top plate 310 is a right-angled trapezoid. Several clamping plates 311 are slidably inserted through the outer wall of the positioning cylinder 307. The cross-section of the clamping plates 311 is a right-angled trapezoid. The inclined side of the clamping plate 311 abuts against the inclined side of the top plate 310. One side of the clamping plate 311 abuts against the arc surface of the rotating shaft 4. When the rotating shaft 4 is inserted into the positioning cylinder 307, the adjusting ring 308 is rotated and moves along the outer wall of the positioning cylinder 307, causing the adjusting ring 308 to press against the sliding ring 309. The sliding ring 309 drives the top plate 310, causing the top plate 310 to press against the inclined side of the clamping plate 311. At this time, the clamping plate 311 will... Simultaneously, move towards the direction of the rotating shaft 4. When the clamping plate 311 abuts against the rotating shaft 4, the rotating shaft 4 can be limited. Rotate the rotating ring 315 to drive the adjusting ring 308 to rotate, so that the adjusting ring 308 separates from the slip ring 309. Then move the slip ring 309 to separate from the top plate 310. When the slip ring 309 separates from the positioning plate, the spring 314 can push the clamping plate 311 to quickly separate from the rotating shaft 4, achieving the effect of quickly disassembling the rotating shaft 4. When the clamping plate 311 separates from the rotating shaft 4, rotate the rotating rod 304 to drive the lead screw 302 to rotate. The lead screw 302 drives the two supporting tripods 301 to move away from each other at the same time. The supporting tripods 301 drive the positioning seat 306, and the positioning seat 306 drives the positioning cylinder 307. When the positioning cylinder 307 separates from the rotating shaft 4, the rotating shaft 4 can be removed. Then, the flooring roll material is placed on the arc surface of the rotating shaft 4. By setting the above structure, the rotating shafts 4 of different sizes can be limited, thereby further improving the applicability of the floor covering unfolding and cutting device.

[0042] A partition 312 is fixedly connected to one side of the clamping plate 311. A limiting rod 313 is slidably passed through the side of the partition 312. One end of the limiting rod 313 is fixedly connected to the outer wall of the positioning cylinder 307. A spring 314 is sleeved on the arc surface of the limiting rod 313. The two ends of the spring 314 are fixedly connected to the limiting rod 313 and the partition 312 respectively. When the moving slip ring 309 drives the top plate 310 to separate from the clamping plate 311, the spring 314 can push the clamping plate 311 to quickly separate from the rotating shaft 4, achieving the effect of quickly disassembling the rotating shaft 4. Furthermore, when the clamping plate 311 moves, the partition 312 fixed on the clamping plate 311 will move along the arc surface of the limiting rod 313, thereby improving the stability of the clamping plate 311 during movement.

[0043] A rotating ring 315 is fixedly connected to the outer wall of the adjusting ring 308, allowing personnel to rotate the adjusting ring 308 with the help of the rotating ring 315, thus achieving convenient control of the adjusting ring 308.

[0044] When the floor covering unfolding and cutting device is needed to unfold and cut the floor covering, first rotate the rotating ring 315 to drive the adjusting ring 308 to rotate, causing the adjusting ring 308 to separate from the slip ring 309. Then move the slip ring 309 to separate from the top plate 310. After the slip ring 309 separates from the positioning plate, the spring 314 can push the clamping plate 311 to quickly separate from the rotating shaft 4, achieving the effect of quickly disassembling the rotating shaft 4. After the clamping plate 311 separates from the rotating shaft 4, rotate the rotating rod 304 to drive the lead screw 302 to rotate. The lead screw 302 drives the two supporting tripods 301 to move simultaneously in a direction away from each other. The supporting tripod 301 drives the positioning seat 306, which in turn drives the positioning cylinder 307. Once the positioning cylinder 307 separates from the rotating shaft 4, the rotating shaft 4 can be removed. Then, the floor covering roll is placed on the arc surface of the rotating shaft 4. After the floor covering roll is placed on the arc surface of the rotating shaft 4, the rotating shaft 4 is positioned between the two positioning cylinders 307. Then, rotating the rotating rod 304 drives the lead screw 302 to rotate. The lead screw 302 drives the two supporting tripods 301 to move towards each other simultaneously. The supporting tripod 301 drives the positioning seat 306, which in turn drives the positioning cylinder 307. After the two positioning cylinders 307 are respectively fitted onto the two ends of the rotating shaft 4, the rotating ring 315 is rotated to drive the adjusting ring 308 to rotate, causing the adjusting ring 308 to press against the sliding ring 309. The sliding ring 309 drives the top plate 310, causing the top plate 310 to press against the inclined side of the clamping plate 311. At this time, the clamping plate 311 will move towards the rotating shaft 4. When the clamping plate 311 abuts against the rotating shaft 4, the limiting of the rotating shaft 4 is completed. After the above operations are completed, the installation of the floor covering and the rotating shaft 4 is completed. Then the floor covering roll on the rotating shaft 4 can be unrolled on the workbench 1. The floor covering can be cut into the required shape using cutting instruments. Personnel can use the scales 5 on both sides of the workbench 1 to determine and mark the cutting position, thereby improving the accuracy of floor covering cutting. When the lead screw 302 rotates to drive the support tripod 301 to move, the guide rod 305 can guide and position the support tripod 301, thereby improving the stability of the support tripod 301 during movement. In addition, when the clamping plate 311 moves, the partition 312 fixed on the clamping plate 311 will move along the arc surface of the limiting rod 313, thereby improving the stability of the clamping plate 311 during movement.
