Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a pre-needling machine. Background Art

[0002] The pre-needling machine is a mechanical device used for needling a highly fluffy but weak fiber web. In addition to the main structure of the needling machine, it also has a reasonable fiber web feeding mechanism, which can make the fluffy fiber web easily enter the needling area under the guidance of the feeding mechanism. The existing fiber web feeding mechanism is composed of a feeding roller and a conveying curtain. The conveying curtain is arranged under the feeding roller, and the two interact with each other to drive the fiber web to move. However, when the gram weight is high, the cotton layer is thick and cannot effectively enter the pre-needling machine, and there is a water ripple phenomenon of the cotton strips when entering the pre-needling, which affects the needling and the quality of the finished product. For this reason, the utility model provides a feeding device for a pre-needling machine. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, a feeding device for a pre-needling machine comprises: a frame 1, wherein the frames 1 are two and are arranged at intervals. A feeding roller 11, a lower conveying curtain 2 and an upper conveying curtain 3 are arranged between the two frames 1. The feeding roller 11 and the upper conveying curtain 3 are arranged above the lower conveying curtain 2. The lower conveying curtain 2 is arranged obliquely, and the upper conveying curtain 3 is arranged horizontally, and a trumpet is formed between the two. Preferably, the inclination angle of the lower conveying curtain 2 is 45 degrees.

[0022] Among them, Figure 2 and Figure 3 As shown, the upper conveying curtain 3 includes a transmission roller 31, a conveying curtain body 32 and a rotating roller 33. The transmission roller 31 and the rotating roller 33 are rotatably arranged between the two frames 1, and the transmission roller 31 is arranged at one end close to the feeding roller 11. The conveying curtain body 32 is sleeved outside the transmission roller 31 and the rotating roller 33. One end of the transmission roller 31 is driven by a driving motor 34 arranged on the frame 1, and the conveying curtain body 32 is driven to move by the transmission roller 31.

[0023] The upper conveying curtain 3 is arranged on one side of the feeding roller 11 through a lifting mechanism, and the lifting mechanism includes a lower slider 4, an upper slider 5, a spring 6 and a cylinder 7.

[0024] like Figure 4 As shown, the lower slider 4 and the upper slider 5 are both slidably arranged in the slide groove 12 opened on the frame 1, and the upper slider 5 is arranged above the lower slider 4. The spring 6 is arranged between the lower slider 4 and the upper slider 5, and the two ends are fixedly connected to the lower slider 4 and the upper slider 5 respectively. The cylinder 7 is arranged on the frame 1, and the end of its piston rod is fixedly connected to the top of the upper slider 5 to drive the upper slider 5 to rise and fall. The two ends of the transmission roller 31 and the rotating roller 33 are connected to the lower slider 4 and move with the lower slider 4. The driving motor 34 is slidably arranged on the frame 1. During adjustment, the upper slider 5 is driven to rise and fall by the cylinder 7, and the compression amount of the spring 6 can be changed, thereby adjusting different pre-pressures.

[0025] A connecting block 8 is arranged on the side of the lower slider 4. The connecting block 8 consists of two pieces, which are symmetrically arranged along the center line of the lower slider 4. The first end of the connecting block 8 is rotatably connected to the lower slider 4, and the second end is provided with an opening 9.

When the connecting block 8 is connected with the upper slider 5 by screws, the upper and lower sliders are fixedly connected together, and the elastic connection is converted into a fixed connection. Furthermore, the frame 1 is provided with second screw holes 13 on both sides of the slide groove 12, which can be used with screws to realize the detachable and fixed connection between the connecting block 8 and the frame 1. Among them, the second screw holes 13 are divided into several groups, which are evenly distributed along the height direction of the slide groove 12. The second screw holes 13 can be used to fix the position of the lower slider 4 by cooperating with the connecting block 8, so that the position of the upper conveying curtain 3 is fixed.

[0027] Preferably, the driving motor 34 is slidably connected to the frame 1 through a sliding bracket 35, and the output end is transmission-connected to the transmission roller 31 through a transmission box 36, and the two legs of the sliding bracket 35 are slidably connected to the slide rails provided on the frame 1. The sliding bracket 35 keeps the driving motor 34 away from the side of the frame 1 to avoid positional conflict between the driving motor 34 and the connecting block 8.
