This feeding device adds an upper conveyor curtain to the feeding mechanism of the pre-needling machine, which can pre-compress thick fiber webs, making the web thinner and allowing it to enter more evenly between the feeding roller and the lower conveyor curtain, thus solving the problem of water ripples on the fabric surface. Furthermore, the upper conveyor curtain's lifting mechanism allows it to be raised and lowered to meet different usage requirements, improving the equipment's applicability.

[0004] However, this type of feeding device has multiple sets of cylinders and motors inside, resulting in a large number of power sources. This not only increases the cost of the equipment but also leads to low equipment stability, which is not conducive to later maintenance work and increases the workload of later maintenance, thus requiring improvement.

[0005] Therefore, a feeding mechanism for a needle punching machine used in the production of needle-punched felt is proposed. Utility Model Content

[0009] Furthermore, an L-shaped plate is provided at one end of the support frame where the active roller is installed, and the motor is fixedly installed on the L-shaped plate.

[0010] Furthermore, a guide seat is installed at each end of the needle plate on the mounting bracket. A sliding groove is provided on the inner side wall of the guide seat in the vertical direction.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown, this utility model embodiment provides a feeding mechanism for a needle punching machine used in needle punching felt production, including a support frame 1. A transmission belt device is provided on the support frame 1. The transmission belt device includes a drive roller 4, a motor 3, a conveyor belt 5, a driven roller 6, a frame plate 7, a sliding block 8, and an adjusting screw 9. The drive roller 4 is rotatably installed at one end of the support frame 1. An L-shaped plate 2 is provided at the end of the support frame 1 where the drive roller 4 is installed. The motor 3 is fixedly installed on the L-shaped plate 2. The frame plate 7 is installed on both sides of the support frame 1. The inner wall of the frame plate 7 is provided with a sliding groove arranged in the left and right direction. The sliding block 8, which is adapted to the structure, is slidably installed inside the sliding groove. The adjusting screw 9 is rotatably installed on the sliding block 8. The inner side of the frame plate 7 is provided with a threaded hole that is adapted to the thread on the surface of the adjusting screw 9. The two ends of the driven roller 6 are rotatably installed in the two sets of sliding blocks 8. The adjusting mechanism is installed on the support frame 1. The conveyor belt 5 is wrapped around the driving roller 4 and the driven roller 6. The driving roller 4 is connected to the motor 3. By rotating the adjusting screw 9 and driving the sliding block 8 to adjust the position under the action of the thread, the position of the driven roller 6 can be moved, thereby adjusting the tension of the conveyor belt 5 and facilitating the maintenance of the conveyor belt 5.

[0028] like Figures 1-2As shown, a mounting frame 11 is also installed on the support frame 1. A needle-piercing plate 10 is slidably mounted on the mounting frame 11, and the needle-piercing plate 10 is located above the transmission belt device. A guide seat 12 is installed on each end of the needle-piercing plate 10 on the mounting frame 11. The inner wall of the guide seat 12 is provided with a vertically oriented sliding groove. Both ends of the needle-piercing plate 10 are provided with protrusion structures that are adapted to the sliding grooves. The protrusion structures are slidably disposed in the sliding grooves, allowing the needle-piercing plate 10 to slide up and down. The sliding groove on the inner wall of the guide seat 12 and the protrusion structures at both ends of the needle-piercing plate 10 can play a limiting and guiding role, improving stability.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, a rotating shaft 13 is rotatably mounted on the mounting bracket 11. The rotating shaft 13 is parallel to the central axis of the drive roller 4. The rotating shaft 13 is connected to the drive roller 4 via a belt drive mechanism. The belt drive mechanism includes pulley A17 and pulley B18. Pulley A17 and pulley B18 are respectively installed on the side ends of the drive roller 4 and the rotating shaft 13, and are located on the same side of the drive roller 4 and the rotating shaft 13. A belt 19 is provided between pulley A17 and pulley B18. During the rotation of the drive roller 4, it will drive the pulley A17 on the side to rotate simultaneously. At this time, under the action of the belt 19, pulley A17 can drive pulley B18 and the rotating shaft 13 to rotate.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the rotating shaft 13 is connected to the needle plate 10 via a crank-connecting rod mechanism. The crank-connecting rod mechanism includes an eccentric wheel 14 and a connecting seat 16. The eccentric wheel 14 is installed in the middle section of the rotating shaft 13, and the connecting seat 16 is installed above the needle plate 10. A connecting plate 15 is hinged between the eccentric wheel 14 and the connecting seat 16. During the rotation of the eccentric wheel 14, under the combined action of the eccentric wheel 14 and the connecting plate 15, the rotational motion of the rotating shaft 13 can be converted into the reciprocating motion of the needle plate 10 sliding up and down along the guide seat 12. Multiple fixing blocks 20 are installed on the side of the needle plate 10. The fixing blocks 20 are provided with mounting holes, and a sliding rod 21 is slidably installed in the mounting holes. The lower end of the sliding rod 21 is connected to a pressure plate 23, which is located below the needle plate 10. A spring 22 is sleeved on the sliding rod 21, and the spring 22 is located between the pressure plate 23 and the fixing blocks 20. The top of the slide rod 21 is located above the fixing block 20, and the top of the slide rod 21 is provided with limiting structures such as screws, limiting rods, and limiting bosses to prevent the slide rod 21 from coming out of the mounting hole of the fixing block 20.

[0031] like Figure 6As shown, a protruding plate 24 is installed on the support frame 1. A vertically oriented groove is provided on the inner wall of the protruding plate 24. A T-shaped block 25 adapted to the structure is inserted inside the groove. A collecting plate 26 is installed on the side of the T-shaped block 25. A limiting piece 27 is rotatably installed below the protruding plate 24. A scraper 28 and an electrostatic brush 29 are installed on the inner wall of the collecting plate 26. The scraper 28 and the electrostatic brush 29 are perpendicularly attached to the conveyor belt 5. When the conveyor belt 5 passes the position of the scraper 28 and the electrostatic brush 29, the excess felt on the surface of the conveyor belt 5 can be effectively brushed off and collected into the collecting plate 26 below, ensuring that the conveyor belt 5 remains clean.

[0032] In operation, this invention works as follows: The motor 3 is started, driving the drive roller 4 to rotate. This, in turn, works with the driven roller 6 to drive the conveyor belt 5 for feeding the needle-punched felt. During the rotation of the drive roller 4, the side pulley A17 rotates simultaneously. Under the action of the belt 19, pulley A17 drives pulley B18 and the rotating shaft 13 to rotate, which in turn drives the eccentric wheel 14 to rotate. During this process, the combined action of the eccentric wheel 14 and the connecting plate 15 propels the rotating shaft 13... The rotational motion is converted into the reciprocating motion of the needle plate 10 sliding up and down along the guide seat 12, thereby realizing the needle-punching work on the lower needle felt. The process is stable. When the needle plate 10 descends, it first drives the pressure plate 23 to contact the lower needle felt, thereby pressing the lower needle felt. Then the upper needle plate 10 presses down and passes through the through groove of the pressure plate 23 to act on the needle felt. During this process, the fixing block 20 slides along the slide rod 21 and compresses the spring 22 to deform. As the eccentric wheel 14 continues to rotate, it works with the connecting plate 15 to drive the needle plate 10 to slide upward along the guide seat 12. At this time, the fixed block 20 will slide upward along the slide rod 21 and gradually reduce the pressure on the spring 22. When the conveyor belt 5 moves to the position of the scraper 28 and the electrostatic brush 29, the electrostatic brush 29 will attract the felt by the attraction generated by the charge and then contact the surface of the conveyor belt 5 to adsorb the felt. The felt will fall into the interior of the collection plate 26 below by gravity, thereby improving the cleaning efficiency and preventing the felt from being scattered into the air and causing dust pollution. After the work is completed, the limiting plate 27 is rotated and it is no longer pressed against the surface of the T-block 25. Then, under the action of gravity, the collection plate 26 can be pulled out along the convex plate 24, so that the interior of the collection plate 26 can be cleaned. When the conveyor belt 5 needs to be maintained, the position of the sliding block 8 can be adjusted by rotating the adjusting screw 9 and the action of the thread, thereby moving the position of the driven roller 6 and adjusting the tension of the conveyor belt 5, which facilitates the maintenance of the conveyor belt 5.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
