As shown in fig. 1 to 4, an unwinding frame includes:

a base 1;

the roller assembly 2 is rotatably arranged on the base 1;

the roller assembly comprises a roller assembly 2, a fixing frame 3, a guide rod 31, a support rod 32, a fixing frame 3 and a base 1, wherein the fixing frame 3 is positioned on two sides of the roller assembly 2, the fixing frame 3 is fixedly connected with the base 1, the guide rod 31 and the support rod 32 are fixedly connected with the fixing frame 3, and the guide rod 31 and the support rod 32 are arranged at intervals;

the baffle subassembly, the baffle subassembly is provided with two sets ofly at least, and the baffle subassembly includes:

the connecting rod 4, the both ends of the connecting rod 4 are equipped with the axle sleeve 41, axle sleeve 41 and connecting rod 4 are fixedly connected, the sliding fit of the axle sleeve 41 is on the guide bar 31, there are connection pieces 42 on the axle sleeve 41, the connection piece 42 and axle sleeve 41 are fixedly connected, there are baffles 43 on the connecting rod 4, the baffle 43 and connecting rod 4 are fixedly connected, the baffle 43 is located above the roller assembly 2;

and the fastener 5, the fastener 5 and the connecting piece 42 are in threaded connection, and one end of the fastener 5 abuts against the support rod 32.

Thus, when the axial movement of the cloth roll needs to be limited, the baffle plate assembly needs to be adjusted, the fastener 5 is rotated firstly, the end part of the fastener 5 is separated from the support rod 32, then the connecting rod 4 is slid, the shaft sleeves 41 at the two ends of the connecting rod 4 slide along the guide rod 31, when the baffle plate 43 is driven to move to a required position by the sliding of the connecting rod 4, the fastener 5 is rotated, one end of the fastener 5 is supported on the support rod 32, the connecting piece 42, the fastener 5 and the support rod 32 are fixed, the baffle plate 43 is fixed, the cloth roll is located between the two baffle plates 43, the axial movement of the cloth roll is limited, and the cloth roll is enabled to rotate in a fixed direction all the time.

In addition, the device also comprises a bearing 6, wherein the bearing 6 is fixed in the shaft sleeve 41, and the guide rod 31 penetrates through the bearing 6. This reduces friction between the boss 41 and the guide rod 31, and allows the boss 41 to slide more smoothly along the guide rod 31.

In addition, the fixing device further comprises an elastic piece 7, the elastic piece 7 is sleeved on the fastening piece 5, and two ends of the elastic piece 7 respectively abut against the supporting rod 32 and the fastening piece 5. In this way, the elastic member 7 gives a supporting force in the axial direction to the fastening member 5, so that loosening of the fastening member 5 can be avoided.

In addition, the cloth guide roller assembly is arranged on one side of the roller assembly 2. In this way, the cloth can be slid in a specific direction. The cloth guide roller assembly comprises a telescopic rod 8, a threaded connecting piece 9, a guide sleeve 10 and a cloth guide roller 11, the guide sleeve 10 is fixed on the base 1, a first connecting hole is formed in the guide sleeve 10, a second connecting hole 81 corresponding to the first connecting hole is formed in the telescopic rod 8, the telescopic rod 8 is inserted into the guide sleeve 10, and the threaded connecting piece 9 penetrates through the first connecting hole and the second connecting hole 81 to connect the guide sleeve 10 and the telescopic rod 8; both ends of the cloth guide roller 11 are rotatably arranged on the telescopic rods 8. In this way, the height of the telescopic bar 8 can be adjusted, and thus the height of the cloth guide roller 11 can be adjusted as needed, and when the height of the telescopic bar 8 is adjusted, the telescopic bar 8 is slid and then the telescopic bar 8 is fixed by threading the screw connection member 9 through the first and second connection holes 81 again.

In addition, a waste collector 12 is also included, the waste collector 12 is placed on the base 1, and the waste collector 12 is positioned below the roller assembly 2. Therefore, the crushed aggregates and dust on the cloth roll can be collected, and the crushed aggregates and dust are prevented from falling to the lower part of the base 1 and are not easy to clean.

In addition, the handle 13 is further included, and the handle 13 is installed on the base 1. Thus, the entire unwinding frame can be pulled easily by the handle 13.

In addition, the roller assembly 2 comprises three rollers which are rotatably connected with the base, and the rollers are arranged at intervals, wherein the rollers positioned on two sides are higher than the rollers positioned in the middle. Thus, when the cloth roll is placed in the roller assembly 2, the cloth roll will not easily fall out of the roller assembly 2 due to the rotation of the cloth roll.

In addition, the roller assembly further comprises guardrails 14, the guardrails 14 are located on two sides of the roller assembly 2, and the guardrails 14 are fixedly connected with the base 1. Therefore, the cloth roll can be prevented from being separated from the unwinding frame after falling out of the roller assembly 2 due to overlarge pulling force.

In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
