Description

Technical Field

[0001] This utility model relates to the field of fabric textile equipment technology, and in particular to a cutting machine unwinding module. 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] The existing technical solution has the following drawbacks: the fabric roll is unwound by two metal rollers. If the thread end of the fabric roll is located directly below the roll, the thread end will fall out from the gap between the two rollers if the unwinding direction is incorrect. Therefore, an improvement is needed. Utility Model Content

[0004] The purpose of this invention is to provide a cutting machine unwinding module 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 cutting machine unwinding module includes a first rotating shaft, a second rotating shaft, a third rotating shaft, and a drive motor. The axes of the first, second, and third rotating shafts are parallel to each other and arranged in a triangular pattern. The first rotating shaft is located in front of the second rotating shaft, and the third rotating shaft is located below the first and second rotating shafts. Multiple first rubber rings are evenly spaced along the axial direction on the third rotating shaft. Each first rubber ring passes around both the first and third rotating shafts. A second rubber ring is arranged between every pair of adjacent first rubber rings, and the second rubber rings pass around both the third and second rotating shafts. A first pulley is fitted onto one end of the third rotating shaft, and a second pulley is fitted onto the output shaft of the drive motor. The first and second pulleys are connected by a gear belt drive.

[0007] By adopting the above technical solution, the fabric roll is placed above the position between the first and second rotating shafts during use. The fabric roll is supported and lifted by the second rubber ring and the first rubber ring. When the third rotating shaft rotates, the power is transmitted to the first and second rotating shafts respectively through the first and second rubber rings, so that the first and second rotating shafts rotate accordingly, thereby driving the fabric roll to rotate.

[0008] In a further embodiment, a first support plate and a second support plate are also included. The first support plate and the second support plate are respectively used to support one end of the first rotating shaft, the second rotating shaft, and the third rotating shaft. Bearing seats are sleeved on both ends of the first rotating shaft, the second rotating shaft, and the third rotating shaft. The bearing seats are fixedly connected to the first support plate / second support plate.

[0009] In a further embodiment, the first support plate is located to the right of the second support plate, and a support frame is fixedly installed on the left side of the first support plate. The drive motor is fixedly connected to the support frame. The support frame includes a first rectangular plate, a rectangular frame, and a second rectangular plate. The rectangular frame is fixedly installed between the first rectangular plate and the second rectangular plate. Each of the four corners of the first rectangular plate is provided with an oblong hole, and the first support plate is provided with round holes that correspond one-to-one with the oblong holes.

[0010] By adopting the above technical solution, since the second pulley of the drive motor is connected to the first pulley through a gear belt during use, in order to adjust the tension of the gear belt, a method of using a slotted hole and a round hole is adopted, so that the bolt is locked with a nut after passing through the slotted hole and the round hole.

[0011] In a further embodiment, a support frame is fixedly installed on the right side of the first support plate and the left side of the second support plate, a lifting cylinder is fixedly installed inside the support frame, and a limit plate is fixedly installed on the top of the lifting cylinder.

[0012] By adopting the above technical solution, a groove that runs through the left and right sides is opened at the top of the limiting plate. This groove is used to hold the two ends of the fabric roll shaft. With the cooperation of the lifting cylinder, the fabric roll can be lowered and raised to realize automatic loading and unloading.

[0013] In a further embodiment, a guide plate is fixedly installed on the top of the support frame, and the two guide plates cooperate with each other to place the roll material in the center.

[0014] In a further embodiment, a plurality of guide wheels are fitted on the first, second, and third rotating shafts, and the guide wheels are used to constrain the position of the first rubber ring / second rubber ring.

[0015] By adopting the above technical solution, the first rubber ring / second rubber ring is prevented from running around when it is driven to rotate. Therefore, guide wheels are used to constrain them. Since the first rubber ring and the second rubber ring are both flexible, the first rubber ring and the second rubber ring are tightened by the fabric roll when the fabric roll is placed on it. When the fabric roll is removed, the first rubber ring and the second rubber ring will be relatively loose. Therefore, guide rings are needed to provide a certain degree of position guidance and limitation.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. The configuration of driving the first and second rubber rings to rotate under the drive of the third rotating shaft can transform the hard contact between the fabric roll and the rotating shaft into a flexible contact. This results in a smaller contact area and relatively greater friction. During unwinding, it is not necessary to locate the head of the fabric roll; the rotation can be driven directly. The flexible contact transforms the point contact between each of the first and second rubber rings and the surface of the fabric roll into a surface contact, which is more conducive to the unwinding process.
