Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a fabric roll loading and unloading module for a cutting machine. Background Technology

[0002] During the use of fabric, it needs to be evenly unrolled into the machine for further processing. The unrolling process requires a fabric unwinding device. Traditional fabric unwinding devices have a simple structure, simply placing the rolled fabric onto a drum and rotating the drum to rotate the fabric for unwinding. During unwinding, there is no fixation in the left, right, front, and back, and the unwinding amount is not precisely positioned, which can easily lead to the rolled fabric becoming loose. In the improved technical solutions, some modules place the fabric roll on two rotating shafts, pressing it firmly against the surfaces of the two rotating shafts by the weight of the fabric roll itself. Then, the tangent property of the two rotating shafts to the fabric roll is used to achieve centered placement and unwinding.

[0003] Existing technologies typically use a fixed-shape U-shaped structure plate to grip fabric rolls, which severely limits the diameter of the fabric roll, making it impossible to handle fabric rolls from different manufacturers and hindering the cutting of complex fabric patterns. Utility Model Content

[0004] The purpose of this invention is to provide a fabric roll loading and unloading module for a cutting machine to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fabric roll pick-and-place module for a cutting machine includes a cylinder, a fixed plate, a first hook, and a second hook. The cylinder is located at the top front of the fixed plate. A fixed block is fixedly installed on the front of the fixed plate. A first round rod and a second round rod are fixedly installed on the front of the fixed block. The first round rod is spaced apart to the right of the second round rod. The top of the first hook is rotatably mounted on the first round rod, and the top of the second hook is rotatably mounted on the second round rod. The top of the first hook is provided with an integrally formed first gear portion, and the top of the second hook is provided with an integrally formed second gear portion, and the first gear portion meshes with the second gear portion. A rotating shaft is rotatably mounted on the top of the second hook. Ear plates are movably mounted on both ends of the rotating shaft, and the two ear plates are fixedly connected to the same connecting plate. The cylinder is fixedly connected to the connecting plate and is used to drive the connecting plate to move left and right. The axes of the rotating shaft, the first round rod, the second round rod, the first gear portion, and the second gear portion are all parallel to each other.

[0007] By adopting the above technical solution, one end of the cylinder is rotatably connected to the fixed plate, and the other end of the cylinder is rotatably connected to the rotating shaft through the connecting plate and the ear plate, so that the cylinder can drive the second hook to rotate around the axis of the second round rod. The top of the second hook moves to the right, which is opposite to the clockwise rotation. Because the first gear part and the second gear part mesh, the first hook rotates counterclockwise. This arrangement allows the bottoms of the first hook and the second hook to cross or separate from each other, thereby realizing the gripping of goods.

[0008] In a further embodiment, the first hook is integrally formed from a first straight edge, a second straight edge, and a third semicircular strip. The second straight edge is used to connect the first straight edge and the third semicircular strip. The rear end face of the third semicircular strip is coplanar with the front end face of the first straight edge, and the thicknesses of the first straight edge, the second straight edge, and the third semicircular strip are the same. The second hook is integrally formed from a third straight edge and a fourth semicircular strip. The front end face of the second hook is coplanar with the front end face of the first straight edge.

[0009] By adopting the above technical solution, when the bottom ends of the first hook and the second hook are close to each other to clamp an object, the fourth semicircular bar of the second hook, which is not connected to the third straight edge, is attached to the bottom of the second straight edge, thus completing the locking action.

[0010] In a further embodiment, a support plate is fixedly installed on the lower left corner of the front side of the fixed plate, and the support plate is rotatably connected to one end of the cylinder.

[0011] In a further embodiment, a rectangular hole extending through the front and back is provided in the middle of the ear plate, and the left and right width of the rectangular hole is the same as the diameter of the rotating shaft, while the top and bottom width of the rectangular hole is more than twice the diameter of the rotating shaft.

[0012] In a further embodiment, a limiting plate is fixedly installed on the front side of the fixing plate, the limiting plate being used to block the first hook and the second hook.

[0013] By adopting the above technical solution, the limiting plate is used to prevent the first hook and the second hook from slipping off the front side of the first round rod and the second round rod.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. One end of the cylinder is rotatably connected to the fixed plate, and the other end of the cylinder is rotatably connected to the rotating shaft through the connecting plate and the ear plate, so that the cylinder can drive the second hook to rotate around the axis of the second round rod. The top of the second hook moves to the right, which is opposite to the clockwise rotation. Because the first gear part and the second gear part mesh, the first hook rotates counterclockwise. This arrangement allows the bottoms of the first hook and the second hook to cross or separate from each other, thereby realizing the gripping of goods. Attached Figure Description
