Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a fabric unwinding device for tension adjustment. Background Technology

[0002] Fabric plays an important role in the clothing and home furnishing industries, and is one of the essential materials. When making bed sheets, bedding sets, bedspreads and other home furnishings, fabric is required as a raw material. During the production process, an unwinding device is used to roll up the fabric. The unwinding and rolling process is used to control the fabric and make it easy to use.

[0003] Existing fabric unwinding devices, due to factors such as different pulling forces and deviations in pulling direction, may result in poor fabric tension during unwinding, causing the fabric to become loose, making it difficult to control the number of unwinding turns, and affecting the smoothness of unwinding.

[0004] Therefore, those skilled in the art have provided a fabric unwinding device with tension adjustment to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a tension-adjustable fabric unwinding device to solve the problem mentioned in the background art that the existing fabric unwinding devices are not easy to adjust and control the tension of the fabric during use, which affects the smoothness of fabric unwinding.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tension-adjustable fabric unwinding device includes: a connecting frame, one end of which is rotatably connected to a rotating shaft, and a pressure frame is fixedly connected to the surface of the rotating shaft; a pressure roller is installed at one end of the pressure frame; an installation shaft is installed on the inner side of the connecting frame; a rotating drum is sleeved on the outer side of the installation shaft; a ring is installed on the outer side of the rotating drum; a telescopic cylinder is connected to the surface of the ring; an unwinding drum is installed on the outer side of the telescopic cylinder; and a motor for driving rotation is connected to the center line pin of one end of the rotating shaft.

[0008] As a further improvement of this utility model: the pressure frame and the rotating shaft are fixedly connected, and the pressure frame and one end of the connecting frame form a rotating structure through the rotating shaft.

[0009] As a further improvement of this utility model: the external structure of the pressure frame is arc-shaped, and one end of the pressure frame and the pressure roller are rotating.

[0010] As a further improvement of this utility model: an auxiliary wheel is rotatably mounted on the inner wall of one end of the connecting frame, and the auxiliary wheel and the pressure wheel are parallel to each other.

[0011] As a further embodiment of this utility model: one end of the mounting shaft is fitted with a locking seat by a set screw, and the mounting shaft forms a rotating structure between the rotating cylinder and the ring.

[0012] As a further improvement of this utility model: the upper surface of the connecting frame is provided with an adjustment groove, and the surface of the adjustment groove is fixedly provided with a locking hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The connecting frame and the pressure frame are rotatably connected by a rotating shaft. The rotating shaft is fixedly connected to the motor. The motor drives the rotating shaft to rotate, which in turn drives the pressure frame to rotate. A pressure roller is installed at the other end of the pressure frame. The pressure roller is made of rubber material. As the pressure frame presses down, the unwinding direction of the fabric will be downward, thereby increasing the tension of the fabric when unwinding and preventing the fabric from becoming loose when unwinding.

[0015] 2. An internal ring is installed on the unwinding drum. A telescopic cylinder is connected to the surface of the ring. A set of telescopic cylinders corresponds to a set of arc-shaped unwinding drums. Together, they form a circular unwinding drum. The telescopic cylinders can be used to push the unwinding drum outward and separate it. In this way, the internal size of the unwinding drum is expanded, which is conducive to increasing the tension of the fabric from the inside of the fabric winding. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a tension-adjustable fabric unwinding device, comprising: a connecting frame 1, one end of which is rotatably connected to a rotating shaft 12, and a pressure frame 5 is fixedly connected to the surface of the rotating shaft 12, one end of which is fitted with a pressure roller 6, an mounting shaft 3 is mounted on the inner side of the connecting frame 1, a rotating drum 11 is sleeved on the outer side of the mounting shaft 3, a ring 9 is mounted on the outer side of the rotating drum 11, a telescopic cylinder 10 is connected to the surface of the ring 9, an unwinding drum 4 is mounted on the outer side of the telescopic cylinder 10, and a motor 8 for driving rotation is connected to the center line pin of one end of the rotating shaft 12.

[0023] The pressure frame 5 is fixedly connected to the rotating shaft 12, and the pressure frame 5 forms a rotating structure with one end of the connecting frame 1 through the rotating shaft 12. The external structure of the pressure frame 5 is arc-shaped, and one end of the pressure frame 5 is a rotating structure with the pressure roller 6. An auxiliary wheel 7 is rotatably installed on the inner wall of one end of the connecting frame 1, and the auxiliary wheel 7 and the pressure roller 6 are parallel to each other.

[0024] Specifically, the arc-shaped pressure frame 5 can pass around the rear of the unwinding drum 4 and then press down and position it from the front of the unwinding drum 4. It is used in conjunction with the pressure roller 6 at one end of the pressure frame 5. Both the pressure roller 6 and the auxiliary roller 7 are in contact with the surface of the fabric and are made of anti-slip rubber material to improve anti-slip performance and prevent the fabric from shifting. The motor 8 drives the rotating shaft 12 to rotate and drives the pressure frame 5 to rotate, adjusting the angle of the pressure frame 5. The pressure frame 5 is used to apply pressure to the fabric, thereby adjusting the tension of the fabric when unwinding.

[0025] One end of the mounting shaft 3 is fitted with a locking seat 2 by a set screw. The mounting shaft 3 forms a rotating structure between the rotating cylinder 11 and the ring 9. The upper surface of the connecting frame 1 is provided with an adjustment groove 13, and a locking hole 14 is fixedly opened on the surface of the adjustment groove 13.

[0026] Specifically, the mounting shaft 3 and the connecting frame 1 are positioned using the locking seat 2. The locking seat 2 and the adjusting groove 13 are a sliding structure, which can adjust the position of the locking seat 2, improve the installation flexibility of the mounting shaft 3 on the connecting frame 1, and lock the positioning with locking bolts. The surface of the ring 9 is provided with a telescopic rod. The output end of the telescopic rod is connected to the inner wall of the unwinding drum 4, while the non-output end is connected to the rotating drum 11. In this way, it is convenient to form a rotating structure between the rotating drum 11 and the mounting shaft 3, which facilitates the unwinding of the fabric.

[0027] The working principle of this utility model is as follows:

[0028] When using this invention, the fabric is rolled up on the surface of the unwinding drum 4. After the fabric is rolled up, it is installed on the connecting frame 1 using the locking seat 2. The locking seat 2 is connected to the locking hole 14 on the surface of the connecting frame 1 via locking bolts. According to the actual tension of the fabric, the telescopic cylinders 10 on the surface of the inner ring 9 of the unwinding drum 4 are used. One set of telescopic cylinders 10 corresponds to one set of separable unwinding drums 4. One set of telescopic cylinders 10 can push one-third of the unwinding drum 4 outward. All three sets of telescopic cylinders 10 can push the unwinding drum 4 simultaneously. This increases the diameter of the unwinding drum 4, thereby increasing the fabric winding tension from the inside. Secondly, when the fabric is unwound, it passes under the pressure roller 6, causing the pressure frame 5 to be positioned above the fabric. The motor 8 drives the rotating shaft 12 to rotate. The pressure frame 5 is fixedly connected to the rotating shaft 12, and then the rotating shaft 12 is rotatably connected to the connecting frame 1. This drives the pressure frame 5 to rotate, causing the pressure frame 5 to press the fabric downwards. In this way, the downward force of the pressure frame 5 increases the tension of the fabric during unwinding.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
