Description

Technical Field

[0001] The present application relates to the technical field of cloth production, and in particular to a cloth unwinding roller frame. Background Art

[0002] The fabric unwinding roller frame is used to unwind the fabric roll, which is equivalent to loading the fabric. The current fabric unwinding roller frame is placed on the ground when in use. There are two rollers on the fabric unwinding roller frame. The fabric roll is placed between the two rollers. The fabric roll is jointly supported by the two rollers. The end of the fabric roll is pulled to other production equipment. When the other production equipment is in operation, the end of the fabric roll is pulled, and the fabric roll can be rolled on the rollers to achieve unwinding. During the unwinding process of the fabric roll, the force in the width direction of the fabric occasionally becomes unbalanced, causing the fabric roll to move in the axial direction of the roller. If the movement time is too long and the movement distance is too large, it is easy to cause the unwound fabric to fold. At the same time, the rotation speeds of the two rollers during the unwinding process may be inconsistent, and over-unwinding is prone to occur during the unwinding process. That is, the section between the fabric roll and other equipment will become too loose. When the unwinding continues, the section is prone to folding. Utility Model Content

DETAILED DESCRIPTION

[0046] In order to make the objectives, technical solutions and advantages of this application more clear, the present application is further described in detail below in conjunction with examples and drawings. The schematic implementation methods of this application and their descriptions are only used to explain this application and are not intended to limit this application.

[0047] like Figure 1-Figure 2As shown, the embodiment of the present application provides a cloth unwinding roller frame, which includes a frame body 1, a first roller 2, a second roller 3, a driving assembly 4 and a limiting assembly 5; the first roller 2 is rotatably connected to the frame body 1; the second roller 3 is rotatably connected to the frame body 1, the second roller 3 is parallel to the axis of the first roller 2 and is arranged at intervals, and the distance between the first roller 2 and the second roller 3 is less than the minimum unwinding diameter of the cloth roll 8; the driving assembly 4 is connected to the frame body 1 and is respectively transmission-connected to the first roller 2 and the second roller 3 to control the first roller 2 and the second roller 3 to rotate around their respective axes on the frame body 1; the two limiting assemblies 5 are respectively slidably connected to the frame body 1, and a placement space that can accommodate the cloth roll 8 is formed between the two limiting assemblies 5, and the size of the placement space changes when the limiting assembly 5 slides on the frame body 1.

[0048] In the embodiments of the present application, the minimum unwinding diameter can be understood as follows: during the unwinding process, the diameter of the fabric roll 8 gradually decreases. When the diameter decreases to a predetermined value, the fabric roll 8 no longer needs to be unwound by the unwinding roller. This diameter is the minimum unwinding diameter. The minimum unwinding diameter can be set to a commonly used value in the industry or can be customized by the staff.

[0049] When in use, the fabric roll 8 is placed on the first roller 2 and the second roller 3, and the free end of the fabric roll 8 is pulled to other production equipment by the staff, so that the two limit components 5 slide on the frame 1 until the axial distance between each limit component 5 and the fabric roll 8 is 5 to 10 mm, and then other production equipment is started, and the driving component 4 is started at the same time to drive the first roller 2 and the second roller 3 to rotate.

[0050] The other production equipment mentioned above refers to any equipment on the fabric production line that has material loading requirements.

[0051] The cloth unwinding roller frame provided in the embodiment of the present application can form axial limitation on the cloth roll 8 by the arrangement of two limit assemblies 5, so as to prevent the cloth roll 8 from axial movement during the unwinding process. At the same time, the placement space between the two limit assemblies 5 can be adjusted by the sliding limit assembly 5, so that it can be suitable for cloth rolls 8 with different axial lengths; through the arrangement of the drive assembly 4, the rotation of the first roller 2 and the second roller 3 is driven by the drive assembly 4, the rotation speed of the first roller 2 and the second roller 3 is controllable, and it is easy to keep consistent, and the problem of over-unwinding is not easy to occur during unwinding. At the same time, the drive assembly 4 can brake the first roller 2 and the second roller 3, so as to prevent the phenomenon of over-unwinding when the unwinding is interrupted.

[0052] In this embodiment of the present application, the frame 1 may include two square connecting plates 93 arranged in parallel and spaced apart. The corresponding corners of the two square plates are connected by a rectangular steel tube. The rectangular steel tube and the connecting plates 93 can be detachably connected to each other to facilitate maintainability. The first roller 2 and the second roller 3 are rotatably connected to the two connecting plates 93 at both ends, thereby enabling the first roller 2 and the second roller 3 to rotate about their respective axes. The drive assembly 4 is connected to one of the connecting plates 93. The limit assembly 5 is slidably connected to the rectangular steel tube.

[0053] It should be noted that, when implementing the above solution, those skilled in the art can, based on common technical knowledge, set, for example, set screws, clamping structures, etc. on the limit component 5 to keep the limit component 5 relatively fixed to the frame 1, to prevent the limit component 5 from shifting when the fabric roll 8 moves.

The fastening member may specifically include an adjusting bolt 55 and a fastening plate 53. The adjusting bolt 55 passes through the support member 51 and is equipped with an adjusting nut 52. The adjusting nut 52 can be configured as a butterfly nut for easy operation by the staff; the fastening plate 53 is connected to the adjusting bolt 55, and a fastening gap is formed between the fastening plate 53 and the support member 51. The limiting assembly 5 is clamped on the frame 1 through the fastening gap, that is, by rotating the butterfly nut, the fastening plate 53 can be close to the rectangular steel tube on the frame 1 and tightly abut against the rectangular steel tube; the baffle 54 is connected to the support member 51, and the baffle 54 is used to form an axial limit for the fabric roll 8.

The end of the first roller 2 can be rotatably connected to the isolation shell 41 through a bearing to ensure smooth rotation, and the end of the second roller 3 can also be rotatably connected to the isolation shell 41 through a bearing to ensure smooth rotation; the first drive gear 42 is coaxially matched with the first roller 2; the second drive gear 43 is coaxially matched with the second roller 3; the reversing gear 44 is located between the first drive gear 42 and the second drive gear 43 and is fitted with the first drive gear 42 and the second drive gear 43 at the same time; the drive motor 45 is matched with the first drive gear 42 to drive the first drive gear 42 to rotate.

[0061] In the embodiment of the present application, the transmission of the second drive gear 43 is achieved through the reversing gear 44, and the first drive gear 42 and the second drive gear 43 can rotate synchronously and in the same direction without having to control the speed of the first roller 2 and the second roller 3 separately. The number of drive motors 45 can be configured to be one, which can reduce the implementation cost and reduce the speed difference caused by control errors.
