Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a fiber opening machine. Background Technology

[0002] Opening is the process of breaking large clumps or blocks of fibers into smaller pieces or bundles. In the production and processing of nonwoven fabrics, it is also one of the methods for handling raw materials.

[0003] The prior art discloses a fiber opening machine (publication number: CN209779071U), which includes a frame, a conveying component and a cylinder assembly mounted on the frame; the front and rear sides of the conveying component are respectively the inlet and outlet, and the conveying component includes drive gears located at both ends and a conveyor belt wrapped around the drive gears; the conveyor belt is inclinedly arranged inside the frame; the cylinder assembly is located above the conveyor belt, and the cylinder assembly includes multiple rollers and tooth tips mounted on the rollers.

[0004] In existing technologies, the loosening rollers are used to break up clumps of fibers. There are two loosening rollers. Existing technologies control the spacing by adjusting the tilt angle of the conveyor belt. Adjusting the conveyor belt requires considering the motion interference of the drive rollers and multiple components. It is easy for slippage to occur due to the change in the wrap angle between the rollers and the conveyor belt caused by the adjustment of the conveyor belt tilt angle. When the conveyor belt angle is adjusted, the position of the loosening rollers does not change. It is difficult for the two loosening rollers to maintain a parallel state with the conveyor belt surface. It is easy for one of the loosening rollers to come into contact with the conveyor belt. Therefore, adjusting the conveyor rollers to control the spacing is more advantageous.

[0005] Therefore, we propose a fiber opening machine. Utility Model Content

[0006] The present invention mainly addresses the technical problem of unreasonable spacing adjustment between the conveyor roller and the conveyor belt, and provides a fiber opening machine.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a fiber opening machine, comprising:

[0008] The machine casing has a first and a second conveyor belt for conveying on the top, and opening rollers are also provided on the side walls of the machine casing.

[0009] An adjustment structure is provided on the side wall of the machine housing for adjusting the position of the opening roller. The adjustment structure includes a main arm, a screw, a locking block, and a thrust groove. The main arm is rotatably connected to the machine housing, and the opening roller is rotatably connected to the main arm. Several thrust grooves are provided on the side wall of the machine housing. The screw is fixedly connected to the main arm and passes through the locking block. The locking block is engaged with the thrust groove. A nut is threaded onto the screw to press and limit the locking block.

[0010] In a preferred embodiment of this utility model, a rotating shaft is fixedly connected to the side wall of the boom, and the rotating shaft is rotatably connected to the chassis.

[0011] In a preferred embodiment of this utility model, a drive motor is fixedly connected to one side of the boom, the output shaft of the drive motor is fixedly connected to the opening roller, and two arc-shaped clearance grooves are opened on the side wall of the machine box. The drive motor is located in one of the clearance grooves, and the thrust groove is opened on the side of the other clearance groove.

[0012] In a preferred embodiment of this utility model, the upper arm forms a rectangular rod structure, the center of the clearance groove is concentric with the rotating shaft, and the width of the clearance groove is smaller than the width of the locking block.

[0013] In a preferred embodiment of this utility model, the wall of the locking block is provided with a through hole, the screw extends through the through hole to one side of the locking block, and the nut and the upper arm are located on both sides of the screw.

[0014] As a preferred embodiment of this utility model, one side of the locking block is provided with an integrally formed limiting protrusion, which can engage with the thrust groove.

[0015] In a preferred embodiment of this utility model, the limiting protrusion forms a block structure that adapts to the thrust groove. The thrust groove is a rectangular slot, and the side wall of the chassis is arranged in a circular array with several identical thrust grooves. The limiting protrusion can be inserted into the thrust grooves at different positions to lock the boom.

[0016] This utility model provides a fiber opening machine. It has the following beneficial effects:

[0017] 1. This fiber opening machine connects the opening roller to the main arm, pushing the main arm to rotate around the shaft at a certain angle, thereby adjusting the distance between the opening roller and the first conveyor belt. This allows control over the degree of fiber dispersal by the opening roller. When adjusting the position of the opening roller, the main arm is pushed to rotate around the shaft, and the nut on the screw wall is tightened. The nut presses the locking block and engages with the thrust groove, locking the angle of the main arm. The drive motor is fixedly connected to the main arm and can independently control the rotation direction of the opening roller. The clearance groove on the machine casing wall can prevent motion interference between the drive motor and the screw and the machine casing, ensuring the stability of the adjustment. The adjustment method is simple and quick, with a wide adjustment range, making it easy to use. The two individually adjustable opening rollers can flexibly adjust their positions while reducing the probability of motion interference with the first conveyor belt, ensuring practicality.

[0018] 2. This fiber opening machine, by setting a limiting protrusion and pressing the locking block with a nut, makes the limiting protrusion enter the thrust groove at the corresponding position, thereby limiting the arm. The limiting effect is better, and it is not easy to loosen. The distance between the opening roller and the first conveyor belt can be controlled more precisely. Attached Figure Description

[0025] A fiber opening machine, such as Figure 1 and Figure 2 As shown, it includes:

[0026] The machine housing 10 has a first conveyor belt 11 and a second conveyor belt 12 for conveying on its top. The side wall of the machine housing 10 is also provided with a loosening roller 13. In this solution, the machine housing 10 forms an open box structure. A material trough for feeding is fixed on one side of the machine housing 10. The first conveyor belt 11 is inclined and the second conveyor belt 12 is horizontal. The first conveyor belt 11 and the second conveyor belt 12 are close to each other and convey materials together. The loosening roller 13 can be a needle cloth roller. The specific model and specifications are not described here. The machine housing 10 can be provided with two loosening rollers 13. The raw materials are broken up by two oppositely rotating loosening rollers 13.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the adjustment structure, located on the side wall of the housing 10, is used to adjust the position of the opening roller 13. The adjustment structure includes a large arm 20, a screw 21, a locking block 22, and a thrust groove 23. The large arm 20 is rotatably connected to the housing 10, and the opening roller 13 is rotatably connected to the large arm 20. Several thrust grooves 23 are formed on the side wall of the housing 10. The screw 21 is fixedly connected to the large arm 20 and passes through the locking block 22. The locking block 22 engages with the thrust groove 23. A nut is threaded onto the screw 21 to press the locking block 22. The boom 20 is tightly limited, and a rotating shaft 30 is fixedly connected to the side wall of the boom 20. The rotating shaft 30 is rotatably connected to the housing 10. A drive motor 31 is also fixedly connected to one side of the boom 20. The output shaft of the drive motor 31 is fixedly connected to the opening roller 13. Two arc-shaped clearance grooves are opened on the side wall of the housing 10. The drive motor 31 is located in one of the clearance grooves, and a thrust groove 23 is opened beside the other clearance groove. The boom 20 forms a rectangular rod structure. The center of the clearance groove is concentric with the rotating shaft 30. The width is less than the width of the locking block 22. A through hole is provided on the wall of the locking block 22. The screw 21 extends through the through hole to one side of the locking block 22. The nut and the large arm 20 are located on both sides of the screw 21. In this design, by connecting the opening roller 13 to the large arm 20, the large arm 20 is pushed to rotate around the rotating shaft 30 by a certain angle. This allows the distance between the opening roller 13 and the first conveyor belt 11 to be adjusted, thus controlling the degree of fiber dispersal by the opening roller 13. When adjusting the position of the opening roller 13, the screw 21 is pushed... The boom 20 rotates around the pivot 30, tightening the nut on the wall of the screw 21. The nut presses the locking block 22 and engages with the thrust groove 23, thereby locking the angle of the boom 20. The drive motor 31 is fixedly connected to the boom 20 and can independently control the rotation direction of the opening roller 13. The clearance groove on the wall of the housing 10 can prevent the drive motor 31 and the screw 21 from interfering with the movement of the housing 10, ensuring the stability of the adjustment. The adjustment method is simple and quick, the adjustment range is wide, and it is easy to use.

[0028] like Figure 5 As shown, a one-piece molded limiting protrusion 24 is provided on one side of the locking block 22. The limiting protrusion 24 can engage with the thrust groove 23. The limiting protrusion 24 forms a block structure that fits the thrust groove 23. The thrust groove 23 is a rectangular slot. Several identical thrust grooves 23 are distributed in a ring array on the side wall of the housing 10. The limiting protrusion 24 can be locked into the thrust groove 23 at different positions to lock the boom 20. As a supplementary explanation to the above scheme, by setting the limiting protrusion 24, the locking block 22 is squeezed by the nut, so that the limiting protrusion 24 enters the thrust groove 23 at the corresponding position, thereby limiting the boom 20. The limiting effect is better and it is not easy to loosen. The spacing between the opening roller 13 and the first conveyor belt 11 is more precisely controlled.

[0029] The working principle of this utility model is as follows: The upper arm 20 is pushed to rotate around the rotating shaft 30 at a certain angle, thereby adjusting the distance between the opening roller 13 and the first conveyor belt 11. This allows control over the degree to which the opening roller 13 disperses the fibers. When adjusting the position of the opening roller 13, the upper arm 20 is pushed to rotate around the rotating shaft 30, tightening the nut on the wall of the screw 21. The nut presses the locking block 22 tightly and engages with the thrust groove 23, causing the limiting protrusion 24 to enter the corresponding thrust groove 23, thus limiting the upper arm 20 and locking its angle. The drive motor 31 is fixedly connected to the upper arm 20 and can independently control the rotation direction of the opening roller 13. The clearance groove on the wall of the housing 10 prevents motion interference between the drive motor 31 and the screw 21 and the housing 10.

[0030] Two individually adjustable opening rollers 13 rotate in opposite directions to break up the clumped fibers, which are then conveyed out via the first and second conveyor belts.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
