Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric winding, in particular to a non-woven fabric winding deviation prevention device. Background Technique

[0002] Non-woven fabric, also known as non-woven cloth or non-woven fabric, is a sheet, web or pad made of fibers arranged in a directional or random manner and combined with each other through friction, interlocking or adhesion, or a combination of these methods; during the production process of non-woven fabric, it is necessary to wind the non-woven fabric so that the non-woven fabric is stored in a roll shape, which is convenient for the storage and transportation of non-woven fabric.

[0003] When the existing device for winding non-woven fabric winds the non-woven fabric, the non-woven fabric is prone to deviation during winding, resulting in uneven winding of the non-woven fabric; at the same time, during the winding process of the non-woven fabric, the non-woven fabric is prone to slack due to uneven tension or winding speed problems, which affects the next operation of the wound non-woven fabric; therefore, we propose a non-woven fabric winding deviation prevention device to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a non-woven fabric winding deviation prevention device to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A non-woven fabric winding deviation prevention device includes a base, two mounting frames are fixedly installed on the top side of the base, bearing bodies are arranged on one side of the two mounting frames close to each other, a winding roller is arranged between the two bearing bodies, and a winding driving mechanism for the winding roller is arranged on one side of the corresponding mounting frame. Limiting retaining rings are arranged on both bearing bodies, two moving grooves are respectively opened on the limiting retaining rings, and the same pressing roller is installed in the corresponding two moving grooves through an elastic mechanism. One ends of the two pressing rollers close to each other abut against the top side wall and the bottom side wall of the winding roller, and a guiding mechanism is arranged between the two limiting retaining rings.

[0007] Preferably, the bearing body is composed of a bearing outer ring, rolling balls and a bearing inner ring, and the two ends of the winding roller are fixedly connected with the bearing inner rings of the two bearing bodies respectively, which is convenient to realize the rotation effect of the winding roller between the two bearing bodies.

[0008] Preferably, the winding driving mechanism includes a motor and a driving rod. A motor is fixedly installed on one side of the corresponding mounting frame, and the output shaft of the motor is fixedly installed at one end of the corresponding winding roller; by starting the motor, the driving rod drives the winding roller to wind the non-woven fabric.

[0009] Preferably, the two limiting retaining ring plates are fixedly connected to the outer rings of the corresponding bearing bodies respectively. The two side walls of the two limiting retaining ring plates are respectively attached between the corresponding mounting brackets and the winding roller. One end of two limiting rods is fixedly installed on one side of the limiting retaining ring plate, and the other ends of the two limiting rods movably penetrate outside the corresponding mounting brackets; when winding the non-woven fabric, the two limiting retaining ring plates play a role in limiting.

[0010] Preferably, the elastic mechanism includes a movable block and a spring. The movable block is movably installed in the movable groove. One side of the movable block is rotatably connected to one end of the pressing roller. One end of the spring is fixedly installed on one side of the movable block, and the other end of the spring is fixedly installed on one side wall of the movable groove; the elastic mechanisms at both ends of the pressing roller are used to press the non-woven fabric wound on the winding roller.

[0011] Preferably, the guiding mechanism includes guiding plates and guiding rollers. Guiding plates are fixedly installed on one side of the two limiting retaining ring plates respectively. Two guiding rollers are rotatably installed on the side of the two guiding plates close to each other. When winding the non-woven fabric, the guiding mechanism is used to limit the non-woven fabric.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] For this non-woven fabric winding anti-deviation device, through the winding driving mechanism, the winding roller winds the non-woven fabric. Through two groups of guiding plates and limiting retaining ring plates, the non-woven fabric during the winding process is limited. As the non-woven fabric is continuously wound and its volume becomes larger and larger, the elastic mechanisms at both ends of the two pressing rollers are used to press the non-woven fabric wound on the winding roller from the top and the bottom. On the one hand, it avoids the situation that the non-woven fabric wound on the winding roller becomes loose, ensuring that the wound non-woven fabric is in a state of moderate tension and facilitating the next operation. On the other hand, through the two pressing rollers, the non-woven fabric wound on the winding roller can be flattened, ensuring the flatness of the non-woven fabric wound by the winding roller.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Refer to Figures 1-4 , a non-woven fabric winding anti-deviation device, including a base 1, two mounting brackets 2 are fixedly installed on the top side of the base 1, bearing bodies 3 are arranged on one side of the two mounting brackets 2 close to each other, a same winding roller 4 is arranged between the two bearing bodies 3, a winding driving mechanism for the winding roller 4 is arranged on one side of the corresponding mounting bracket 2, limiting retaining ring plates 7 are arranged on both bearing bodies 3, two movable grooves 8 are respectively opened on the limiting retaining ring plates 7, and a same pressing roller 11 is installed in the corresponding two movable grooves 8 through an elastic mechanism. One ends of the two pressing rollers 11 close to each other are respectively abutted against the top side wall and the bottom side wall of the winding roller 4, and a guiding mechanism is arranged between the two limiting retaining ring plates 7.

[0021] Further, the bearing body 3 is composed of a bearing outer ring, rolling balls and a bearing inner ring. The two ends of the winding roller 4 are fixedly connected with the bearing inner rings of the two bearing bodies 3 respectively, which is convenient to realize the rotation effect of the winding roller 4 between the two bearing bodies 3.

[0022] Specifically, the winding driving mechanism includes a motor 5 and a driving rod 6. A motor 5 is fixedly installed on one side of the corresponding mounting bracket 2, and the output shaft of the motor 5 is fixedly installed at one end of the corresponding winding roller 4; by starting the motor 5, the driving rod 6 drives the winding roller 4 to wind the non-woven fabric.

[0023] Specifically, the two limiting retaining ring plates 7 are fixedly connected with the bearing outer rings of the corresponding bearing bodies 3 respectively. The two side walls of the two limiting retaining ring plates 7 are respectively attached between the corresponding mounting bracket 2 and the winding roller 4. One end of two limiting rods 12 is fixedly installed on one side of the limiting retaining ring plate 7, and the other ends of the two limiting rods 12 movably penetrate outside the corresponding mounting bracket 2; when winding the non-woven fabric, the two limiting retaining ring plates 7 play a role in limiting.

[0024] Further, the elastic mechanism moving block 9 and the spring 10 are provided. The moving block 9 is movably installed in the moving groove 8. One side of the moving block 9 is rotatably connected to one end of the pressure roller 11. One end of the spring 10 is fixedly installed on one side of the moving block 9, and the other end of the spring 10 is fixedly installed on one side wall of the moving groove 8. The non-woven fabric wound on the winding roller 4 is pressed by the elastic mechanism at both ends of the pressure roller 11.

[0025] Specifically, the guiding mechanism includes a guiding plate 13 and guiding rollers 14. The guiding plates 13 are fixedly installed on one side of the two limiting retaining ring plates 7 respectively. Two guiding rollers 14 are rotatably installed on the side of the two guiding plates 13 close to each other. When winding the non-woven fabric, the non-woven fabric is limited by the guiding mechanism.

[0026] During use: When winding the non-woven fabric, one end of the non-woven fabric passes through the gap between the two guiding rollers 14 and is wound around the winding roller 4. By starting the motor 5, the driving rod 6 drives the winding roller 4 to wind the non-woven fabric. The non-woven fabric during the winding process is limited by the two groups of guiding plates 13 and the limiting retaining ring plates 7. As the non-woven fabric is continuously wound and its volume becomes larger and larger, the non-woven fabric wound on the winding roller 4 pushes the two pressure rollers 11 apart from each other. At this time, the two groups of springs 10 are deformed and compressed under force. On the one hand, under the elastic force of the two groups of springs 10, the non-woven fabric wound on the winding roller 4 is pressed from the upper and lower directions by the two pressure rollers 11, avoiding the situation of the non-woven fabric wound on the winding roller 4 being loose, and ensuring that the wound non-woven fabric is in a state of moderate tension for the next operation. On the other hand, the two pressure rollers 11 can flatten the non-woven fabric wound on the winding roller 4, ensuring the flatness of the non-woven fabric wound by the winding roller 4.
