Technical Field

[0001] The utility model belongs to the technical field of opening equipment, and specifically relates to a needle felt opening equipment. Background Art

[0002] Needle-punched felt is a filter material with reasonable structure and good performance. It is made of glass fiber as raw material. The combed short-cut glass fiber felt is needle-punched with a needle. The glass fibers in the felt layer and between the glass fibers in the felt layer and the reinforced glass fiber base cloth are entangled with each other by mechanical methods, and the fiber web is reinforced to form a felt-like non-woven filter material.

[0003] The existing needle-punched felt needs to be loosened during production, and is usually processed using an opening roller. However, during the rotation of the opening roller, part of the needle-punched felt will be entangled on the opening roller. When too much needle-punched felt is entangled, the bottom of the opening teeth will be covered, affecting the opening effect. Utility Model Content

[0004] In view of this, the utility model provides a needle felt opening device for solving the technical problem that when too much needle felt is wound around an opening roller, the bottom of the opening teeth will be covered, thereby affecting the opening effect.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a needle felt opening device, which comprises an opening box, wherein two opening rollers are rotatably installed in the opening box, a plurality of opening teeth are evenly distributed on the opening rollers, and a plurality of scraping components are arranged on two opposite inner walls of the opening box;

[0007] The scraping assembly comprises a support tube fixedly mounted on the inner wall of the opening box, a slide groove is provided in the support tube, a through hole is provided on the side wall of the support tube facing the opening roller, the through hole is connected with the slide groove and a cleaning tooth is slidably connected inside, the cleaning tooth and the opening tooth are staggered, and the outer end of the cleaning tooth abuts against the circumferential surface of the opening tooth;

[0008] An inner magnetic plate is fixedly mounted on one end of the slide slot close to the opening box, an outer magnetic plate fixedly mounted on the inner end of the cleaning tooth is slidably connected in the slide slot, and springs are directly fixedly mounted on the inner magnetic plate and the outer magnetic plate.

[0009] On the basis of the above technical solution, the needle felt opening device of the utility model can also be improved as follows:

[0010] Furthermore, a plurality of cleaning blocks are fixedly mounted on two opposite inner walls of the opening box, a cleaning groove for the opening teeth to pass through is vertically opened in the middle of the cleaning block, and the position of the cleaning groove corresponds to the position of the opening teeth.

[0011] Furthermore, a plurality of spike-shaped protrusions are fixedly installed at equal intervals on the inner wall of the cleaning groove.

[0012] Furthermore, a motor seat is fixedly mounted on one outer wall of the opening box, a driving motor is fixedly mounted on the motor seat, and two mutually meshing transmission wheels are arranged on the other outer wall of the opening box.

[0013] Furthermore, the output shaft of the driving motor is fixedly connected to the front end of one of the opening rollers, and the rear ends of the two opening rollers are fixedly mounted to the transmission wheel.

[0014] Furthermore, guide plates are fixedly mounted on two opposite inner side walls of the opening box, the two guide plates are respectively located above the opening rollers, and the two guide plates are inclined downward.

[0015] Compared with the prior art, the needle felt opening device provided by the utility model has the beneficial effect that by arranging the sliding of the cleaning teeth, it is avoided that after the needle felt is wrapped around the opening roller, the outer peripheral surface of the opening roller is locally thickened, causing the cleaning teeth to restrict the movement of the opening roller.

[0016] By arranging two inclined guide plates, the gap between the lower ends of the two guide plates corresponds to the gap position between the two opening rollers, so that the needle felt can fall between the two opening rollers. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-5 As shown, the utility model provides a needle felt opening device, comprising an opening box 1, wherein two opening rollers 2 are rotatably installed in the opening box 1, a plurality of opening teeth 20 are evenly distributed on the opening rollers 2, and a plurality of scraping components are arranged on two opposite inner walls of the opening box 1;

[0031] The scraping assembly includes a support tube 21 fixedly mounted on the inner wall of the opening box 1, a slide groove 22 is provided in the support tube 21, a through hole is provided on the side wall of the support tube 21 facing the opening roller 2, the through hole is connected to the slide groove 22 and a cleaning tooth 23 is slidably connected inside, the cleaning tooth 23 is staggered with the opening tooth 20, and the outer end of the cleaning tooth 23 abuts against the circumferential surface of the opening tooth 20;

[0032] An inner magnetic plate 24 is fixedly mounted on one end of the slide groove 22 close to the opening box 1 , and an outer magnetic plate 25 fixedly mounted on the inner end of the cleaning tooth 23 is slidably connected in the slide groove 22 , and a spring 26 is directly fixedly mounted between the inner magnetic plate 24 and the outer magnetic plate 25 .

[0033] Optionally, in the above technical solution, a plurality of cleaning blocks 4 are fixedly installed on two opposite inner walls of the opening box 1, and a cleaning groove 41 for the opening teeth 20 to pass through is vertically opened in the middle of the cleaning block 4, and the position of the cleaning groove 41 corresponds to the position of the opening teeth 20.

[0034] Optionally, in the above technical solution, a plurality of spike-shaped protrusions 42 are fixedly installed at equal intervals on the inner wall of the cleaning groove 41 .

[0035] Optionally, in the above technical solution, a motor base 11 is fixedly mounted on the outer wall of one side of the opening box 1, a driving motor 12 is fixedly mounted on the motor base 11, and two mutually meshing transmission wheels 13 are provided on the outer wall of the other side of the opening box 1.

[0036] Optionally, in the above technical solution, the output shaft of the driving motor 12 is fixedly connected to the front end of an opening roller 2 , and the rear ends of the two opening rollers 2 are fixedly mounted to the transmission wheel 13 .

[0037] Optionally, in the above technical solution, guide plates 10 are fixedly installed on two opposite inner side walls of the opening box 1, and the two guide plates 10 are respectively located above the opening rollers 2, and the two guide plates 10 are inclined downward.

[0038] Working principle:

[0039] When in use, the driving motor 12 is started to drive the opening roller 2 connected thereto to rotate, and the rotating opening roller 2 drives the transmission wheel 13 at the rear end to rotate, so that the other opening roller 2 rotates synchronously, and the needle felt to be opened is put into the top of the opening box 1, and falls between the two opening rollers 2 along the two guide plates 10 for opening processing;

[0040] During the rotation of the opening roller 2, the outer ends of the cleaning teeth 23 always abut against the circumferential surface of the opening roller 2. When the needle felt is wound around the opening roller 2, the abutment of the cleaning teeth 23 can clean it in time, thus preventing too much needle felt from being wound around the opening roller 2, causing debris to accumulate on both sides of the opening teeth 20.

[0041] The inner magnetic plate 24 and the spring 26 repel each other. Specifically, when the outer peripheral surface of the opening roller 2 is partially thickened, the cleaning teeth 23 can drive the outer magnetic plate 25 to move into the support tube 21, squeezing the spring 26. When the debris at the thickened part is scraped off, the cleaning teeth 23 are always in contact with the outer peripheral surface of the opening roller 2 through the rebound of the spring 26 and the repulsion between the inner magnetic plate 24 and the outer magnetic plate 25.

[0042] When the opening roller 2 rotates, the opening teeth 20 that rotate along with it can pass through the corresponding cleaning grooves 41, and the opening teeth 20 abut against the protrusions 42, so that the protrusions 42 can scrape off the debris on the opening teeth 20 in time, avoiding excessive accumulation of debris on the opening teeth 20 and affecting the opening effect.

[0043] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
