Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interior decoration processing equipment, and in particular relates to a sewn non-woven fabric opening, loosening and impurity removing device. Background Art

[0002] At present, many car interiors are made of non-woven fabrics. During the production process, a lot of stitched non-woven fabrics (that is, non-woven fabric waste) will be produced. If the stitched non-woven fabrics are directly discarded, it will be very wasteful. Therefore, the market generally uses an opening machine to open the stitched non-woven fabrics, and the stitched non-woven fabrics are opened into single fibers for secondary use. Since the stitched non-woven fabrics are woven more tightly, some fiber nodules or fiber blocks will be produced during the opening process. If they are mixed in the opened fibers, there will be a hidden danger of damaging the process parts during the subsequent reuse. Therefore, they need to be removed and collected. In order to solve this problem, this solution was created. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a device for loosening and removing impurities from stitched non-woven fabrics. It will use its own heavy weight to set a reasonable spacing between the fiber knots or fiber blocks generated in the process of opening the stitched non-woven fabrics, and discharge the fallen fiber debris outside the equipment through a guide plate for collection.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a stitched non-woven fabric opening and impurity removal device, comprising three opening rollers, a material guide plate and a feeding conveyor belt, the three opening rollers are arranged at intervals, the material guide plate is located below the three opening rollers, the water surface projection of the material guide plate covers the horizontal plane projection of the output ends of the three opening rollers, and the feeding conveyor belt is located at the output end of the material guide plate.

[0013] 1. The utility model provides a stitched non-woven fabric opening and impurity removing device. The stitched non-woven fabric is opened between three opening rollers. During the opening process, single fibers and nodules or fiber blocks are formed. Since the nodules or fiber blocks themselves have a certain weight, under the influence of gravity, the nodules or fiber blocks will fall onto the guide plate below the opening roller, and then fall from the guide plate onto the feeding conveyor belt. The feeding conveyor belt operates in real time to discharge the nodules or fiber blocks to the output end of the feeding conveyor belt.

[0019] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0020] like Figure 1-Figure 3 As shown, this embodiment provides a stitch-bonded non-woven fabric opening and impurity removal device, including a frame 1, three opening rollers 2, a material guide plate 3, a feeding conveyor belt 4 and a material suction component.

[0021] The frame 1 includes a feeding part and a receiving part. The feeding part is located on one side of the receiving part. The feeding part is provided with a feeding conveyor belt 11. The receiving part has an installation notch. Three opening rollers 2 and a guide plate 3 are located in the installation notch. The frame forms a first chamber 13. The first chamber 13 is located below the outer opening roller. The side wall of the first chamber 13 has a discharge port. The bottom of the first chamber 13 is an inclined plate. The suction assembly is located on one side of the frame. The suction assembly includes a suction bin 5 and an air pump 51. The discharge port is connected to the suction bin 5 through a pipeline. The air pump 51 is located on the side wall of the suction bin 5. The air pump 51 is used for suction. The suction of the air pump 51 creates a negative pressure for the suction bin 5, so that the single fiber opened by the opening roller is sucked into the suction bin 5 for collection.

[0022] The three opening rollers 2 are arranged at intervals. Specifically, the opening rollers 2 have a plurality of opening rings arranged at intervals at the ends thereof. The opening rings are composed of a plurality of inverted hooks arranged at intervals in annular shapes and facing the same direction. A dust cover 12 is arranged above the three opening rollers 2. The guide plate 3 is located below the three opening rollers 2 and is arranged obliquely. The water surface projection of the guide plate 3 covers the horizontal plane projection of the output ends of the three opening rollers 2. The feeding conveyor belt 4 is located at the output end of the guide plate 3. Preferably, the peripheral surface of the feeding conveyor belt 4 has a plurality of pushing convex strips, which are arranged at intervals along the peripheral surface of the feeding conveyor belt 4 to push the debris toward the output end of the feeding conveyor belt.

[0023] The stitched nonwoven fabric is opened between three opening rollers 2. During the opening process, the debris on the stitched nonwoven fabric will be removed by the opening rollers 2 and then fall onto the guide plate 3 below the opening rollers 2. Under the action of gravity, the debris falls from the guide plate 3 onto the feeding conveyor belt 4 and is then discharged from the feeding conveyor belt 4 in time. After being discharged, it is uniformly collected and processed.

[0024] In another embodiment, in order to increase the time for debris to fall off, based on the above, a sewn non-woven fabric debris removal device further includes a vacuum device (not shown in the figure) and a receiving seat (not shown in the figure).

[0025] The accommodating seat has an installation cavity, the feeding conveyor belt 4 is located in the installation cavity, the area between the guide plate 3 and the installation cavity forms a chamber, and a vacuum device is installed on the side wall of the accommodating seat. Specifically, there is an air inlet on the accommodating seat, and a filter screen is arranged at the air inlet. The vacuum device is an air pump 51, and the air pump 51 is connected to the air inlet through an air pipe. The air pump 51 is used to suck air, so that the air pressure in the chamber is lower than the external air pressure. When the opening roller 2 removes the debris, the debris can be quickly separated from the opening roller 2 and then pass through the guide plate 3 to enter the feeding conveyor belt 4. The air suction volume of the air pump 51 is adjusted according to the actual situation, and the air pump 51 is adjusted to prevent the debris from being adsorbed on the filter screen.

[0026] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
