Description

Technical Field

[0001] This utility model relates to the field of fiber cotton feeding technology, specifically to a swing-type fiber cotton feeding mechanism. Background Technology

[0002] Fiber cotton is a fluffy, cotton-like material made from chemical or natural fibers. It is lightweight, soft, warm, and breathable, and is widely used in home textiles, clothing, filtration, and sound insulation. It is not traditional natural cotton, but rather a fiber aggregate produced industrially, whose composition and properties can be flexibly adjusted according to needs.

[0003] In the production and preparation of fiber cotton, the oscillating feeding mechanism is mainly used for the spreading, leveling, and layering of fiber cotton. It is mainly used to evenly distribute the fiber cotton on the conveyor belt to provide fiber cotton layers for subsequent processing. Some existing oscillating fiber cotton feeding mechanisms use a crank to rotate and drive a connecting rod to move, which in turn pushes the end of the conveyor belt to oscillate back and forth to lay the fiber cotton on the conveyor belt. However, during the process of the crank rotating and driving the conveyor belt to oscillate, the oscillation speed of the conveyor belt end near the edge of the conveyor belt is lower than that of other positions, while the conveying speed of the conveyor belt is constant. This results in the fiber cotton layer on the conveyor belt being thicker on both sides and thinner in the middle, leading to inconsistent fiber cotton thickness and uneven structure, which affects subsequent processing. Utility Model Content

[0004] The purpose of this invention is to provide a swing-type fiber feeding mechanism to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a swing-type fiber cotton feeding mechanism, comprising a frame and a conveyor belt, wherein a rotating shaft is rotatably mounted on the frame, one end of the conveyor belt is fixedly connected to the rotating shaft, and a rotating mechanism is rotatably mounted on the frame; a drive rod is rotatably mounted inside the frame, and a reciprocating spiral groove is formed on the outer circumferential surface of the drive rod, and a moving block that cooperates with the reciprocating spiral groove is slidably mounted on the drive rod; a toothed plate is fixedly mounted on the top of the moving block, and a gear that meshes with the toothed plate is fixedly mounted at the bottom of the rotating mechanism.

[0006] Preferably, the reciprocating spiral groove includes a first spiral groove and two second spiral grooves.

[0007] Preferably, the moving block is fixedly provided with an abutting ball adapted to the reciprocating spiral groove.

[0008] Preferably, a limit rod is fixedly installed inside the frame, and the toothed plate is slidably connected to the limit rod.

[0009] Preferably, the rotating mechanism includes a rotating column fixedly mounted on a toothed plate, a rotating plate fixedly mounted on the rotating column, a connecting block rotatably mounted at the end of the rotating plate away from the rotating column, and a connecting rod rotatably mounted on the connecting block.

[0011] In the above technical solution, the present invention provides a swing-type fiber cotton feeding mechanism, which has the following beneficial effects: by rotating the drive rod, the first spiral groove and the second spiral groove in the reciprocating spiral groove drive the moving block to move at different speeds, thereby causing the rotating plate to rotate at different speeds, so that the swing speed of the conveyor belt increases when it is close to the side of the conveyor belt, thereby reducing the thickness of the fiber cotton layer laid on the side of the conveyor belt and making the thickness of the fiber cotton layer on the conveyor belt uniform.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-6 A swing-type fiber cotton feeding mechanism, the technical solution proposed in this utility model includes a frame 3 and a conveyor belt 1. A rotating shaft 6 is rotatably mounted on the frame 3, and one end of the conveyor belt 1 is fixedly connected to the rotating shaft 6. A rotating mechanism is rotatably mounted on the frame 3. A drive rod 10 is rotatably mounted inside the frame 3. A reciprocating spiral groove 11 is opened on the outer circumference of the drive rod 10. A moving block 13 that cooperates with the reciprocating spiral groove 11 is slidably mounted on the drive rod 10. A toothed plate 15 is fixedly mounted on the top of the moving block 13. A gear 17 that meshes with the toothed plate 15 is fixedly mounted at the bottom of the rotating mechanism. A conveyor belt for carrying the fiber cotton layer is parallel to the drive rod 10. The conveying speed of conveyor belt 1 remains constant. One end of conveyor belt 1 is fixedly connected to the rotating shaft 6. Conveyor belt 1 is rotatably connected to the frame 3 via the rotating shaft 6. When the rotating mechanism rotates, it pushes the conveyor belt 1 to reciprocate around the axis of the rotating shaft 6. The pitch of the reciprocating spiral groove 11 is different at the middle position and at both ends. When the drive rod 10 is rotated, the moving block 13 is driven to reciprocate along the drive rod 10 through the reciprocating spiral groove 11. Because the pitch of the reciprocating spiral groove 11 is different at different positions, the moving block 13 does not move at a uniform speed. When the moving block 13 moves, it drives the toothed plate 15 to move. When the toothed plate 15 reciprocates, it drives the gear 17 to reciprocate. Figure 4 As shown, the moving block 13 moves from the right end to the left end of the reciprocating spiral groove 11, and the toothed plate 15 can only drive the gear 17 to rotate half a turn. When the rotating mechanism pushes the end of the conveyor belt 1 close to the side of the conveyor belt, the moving block 13 also moves to the position with the larger pitch of the reciprocating spiral groove 11, thereby accelerating the movement of the moving block 13 and the toothed plate 15, and thus driving the rotation speed of the rotating mechanism, so that the end of the conveyor belt 1 moves faster when it is close to the side of the conveyor belt, thereby reducing the amount of fiber cotton falling on the side of the conveyor belt, and making the fiber cotton layer on the conveyor belt uniform in thickness.

[0023] Specifically, the reciprocating spiral groove 11 includes a first spiral groove 12 and two second spiral grooves 121; the two second spiral grooves 121 are located at both ends of the first spiral groove 12, the first spiral groove 12 and the second spiral grooves 121 are interconnected, the first spiral groove 12 and the second spiral grooves 121 each contain two spiral grooves with opposite spiral directions, and the pitch of each second spiral groove 121 is greater than the pitch of the first spiral groove 12.

[0024] Specifically, a contact ball 14 adapted to the reciprocating spiral groove 11 is fixedly installed inside the moving block 13; the contact ball 14 is located inside the reciprocating spiral groove 11, and the moving block 13 moves back and forth along the drive rod 10 through the cooperation of the reciprocating spiral groove 11 and the contact ball 14, and the moving speed of the moving block 13 is controlled.

[0025] Specifically, a limit rod 16 is fixedly installed inside the frame 3, and the toothed plate 15 is slidably connected to the limit rod 16; the limit rod 16 limits the toothed plate 15, thereby preventing the moving block 13 from rotating when the drive rod 10 rotates. The limit rod 16 can also support the toothed plate 15 to ensure that the toothed plate 15 meshes with the gear 17.

[0026] Specifically, the rotating mechanism includes a rotating column 18 fixedly mounted on the toothed plate 15, a rotating plate 19 fixedly mounted on the rotating column 18, a connecting block 20 rotatably mounted on the end of the rotating plate 19 away from the rotating column 18, and a connecting rod 21 rotatably mounted on the connecting block 20. The rotating plate 19 is rectangular. When the moving block 13 rotates, it drives the gear 17 to rotate through the toothed plate 15. The gear 17 drives the rotating plate 19 to rotate through the rotating column 18. The rotating plate 19 drives one end of the connecting rod 21 to rotate around the axis of the rotating column 18. The end of the connecting rod 21 away from the rotating plate 19 is rotatably connected to the side of the conveyor belt 1 near the rotating shaft 6. When the rotating plate 19 rotates, it pushes the conveyor belt 1 to swing through the connecting rod 21.

[0027] Specifically, two support frames 5 are fixedly installed at the bottom of the conveyor belt 1, and a fixed rod 7 is fixedly installed between the two support frames 5. The end of the connecting rod 21 away from the rotating plate 19 is rotatably connected to the fixed rod 7. A first drive motor 2 is fixedly installed on the conveyor belt 1 to drive the conveyor belt 1 to run, and a second drive motor 9 is fixedly installed on the frame 3. The output end of the second drive motor 9 is fixedly connected to the drive rod 10. The second drive motor 9 drives the drive rod 10 to rotate. The support frame 5 of the conveyor belt 1 near the second drive motor 9 is rotatably connected to the rotating shaft 6. When the rotating plate 19 rotates, it pushes the fixed rod 7 to move through the connecting rod 21, so that the conveyor belt 1 rotates around the axis of the rotating shaft 6. The frame 3 has an arc groove 4, and a support wheel 8 is fixedly installed at the bottom of the support frame 5 away from the second drive motor 9. The support wheel 8 moves in the arc groove 4. The arc of the arc groove 4 is consistent with the trajectory of the support wheel 8 swinging when the conveyor belt 1 rotates. The support wheel 8 can support the conveyor belt 1 and reduce the friction between the conveyor belt 1 and the frame 3 when the conveyor belt 1 swings. The length of the reciprocating spiral groove 11 is only enough for the toothed plate 15 to move and drive the gear 17 to rotate half a revolution. The length of the first spiral groove 12 in the reciprocating spiral groove 11 is the same as the sum of the lengths of the two second spiral grooves 121. The pitch of each second spiral groove 121 is 2-2.4 times the pitch of the first spiral groove 12.

[0028] Working principle: In the initial state, connecting rod 21 is perpendicular to the side wall of frame 3. At this time, rotating plate 19 is also perpendicular to the side wall of frame 3. The end of conveyor belt 1 away from rotating shaft 6 is located on the side of conveyor belt close to rotating plate 19. At this time, moving block 13 is located at the top of the second spiral groove 121 at the right end of reciprocating spiral groove 11. When in use, the second drive motor 9 is started to drive drive rod 10 to rotate. The rotation of drive rod 10 drives toothed plate 15 to move away from the second drive motor 9 through the second spiral groove 121 and abutting ball 14, thereby driving gear 17 to rotate. Figure 4 When the abutting ball 14 moves to the left from the second spiral groove 121 into the first spiral groove 12, the moving speed of the moving block 13 decreases, the toothed plate 15 drives the gear 17 to rotate 45 degrees, thereby driving the rotating plate 19 to rotate 45 degrees and pushing the conveyor belt 1 to swing. The drive rod 10 continues to rotate, and the abutting ball 14 moves from the right end to the left end of the first spiral groove 12. At this time, the end of the conveyor belt 1 is pushed by the connecting rod 21 to the vicinity of the side of the conveyor belt away from the rotating plate 19. Subsequently, the abutting ball 14 enters the second spiral groove 121 on the left side, and the moving speed of the abutting ball 14 increases, thereby increasing the rotation speed of the rotating plate 19, and thus increasing the swing speed of the end of the conveyor belt 1 when it is close to the side of the conveyor belt, making the overall swing speed of the conveyor belt 1 more uniform, thereby preventing the fiber cotton layer on the conveyor belt from being thick on both sides and thin in the middle.
