Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production and processing equipment, in particular to fiber pretreatment equipment for non-woven fabric production. Background Art

[0002] Before the existing non-woven fabric production, it is generally necessary to carry out fiber opening pretreatment, that is, to tear the large fiber clumps and blocks into small pieces and small bundles. Opening reduces the scale of the lateral connection of the fibers, creating conditions for further loosening to a single state in the future. In the past, fiber pretreatment equipment could not completely loosen the fibers during the opening pretreatment, resulting in fiber aggregation, resulting in poor subsequent non-woven fabric forming effects; and when the small fiber pieces after opening were collected together, the small fiber pieces were easy to fly away. Utility Model Content

[0003] The purpose of the present application is to provide a fiber pretreatment device for non-woven fabric production, aiming to solve the above-mentioned problems in the prior art.

[0004] The present application provides a fiber pretreatment equipment for non-woven fabric production, including a loosening bin, a feeding port fixedly opened at the top of the loosening bin, and blowers fixedly connected to both sides of the feeding port; a main loosening roller is rotatably connected to the box body of the loosening bin via a rotating shaft, and an auxiliary loosening roller is respectively connected to the left and right sides of the main loosening roller; the bottom end of the loosening bin is connected to a transition bin, and a baffle is rotatably connected to the transition bin via a rotating shaft; the bottom end of the transition bin is connected to a storage bin, and a push plate is slidably connected to the storage bin, and a hydraulic telescopic rod and a limit rod are fixedly connected to the push plate, and the limit rod is slidably connected in a limit groove, and the limit groove and the hydraulic telescopic rod are fixedly connected to the storage bin via a support block, and the storage bin and the support block are fixedly connected to the bottom plate, and a support foot is fixedly connected to the lower surface of the bottom plate.

[0009] Furthermore, a side of the transition bin away from the push plate is an inclined surface.

[0010] The beneficial effects of the utility model are as follows: the utility model can repeatedly loosen the fiber clusters in the loosening bin to prevent the fiber aggregation; the blower is used to blow the loosened fiber pieces in the loosening bin into the storage bin to prevent the fiber pieces from adhering to the main loosening roller and the auxiliary loosening roller; the inclined transition bin is used to make the fiber pieces fall away from the discharge port, and the push plate concentrates the fiber pieces in the storage bin out of the discharge port to prevent the fiber pieces from flying.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 and Figure 2The fiber pretreatment equipment for non-woven fabric production shown in the figure includes an opening bin 1, a feed inlet 2 is fixedly opened at the top of the opening bin 1, and blowers 3 are fixedly connected on both sides of the feed inlet 2. The blowers 3 are used to blow the fiber pieces that have been opened in the opening bin 1 into the storage bin 4 to prevent the fiber pieces from adhering to the main opening roller 5 and the auxiliary opening roller 6. The main opening roller 5 is rotatably connected to the box body of the opening bin 1 through a rotating shaft, and an auxiliary opening roller 6 is connected to the left and right sides of the main opening roller 5. The auxiliary opening roller 6 cooperates with the main opening roller 5 to tear large fiber clumps and blocks into small pieces and bundles. The bottom end of the opening bin 1 is connected to the transition bin 7, and a baffle 8 is rotatably connected to the transition bin 7 through a rotating shaft. The baffle 8 can rotate on the transition bin 7, and the rotating shaft is controlled by a motor. The bottom end of the transition bin 7 is connected to the storage bin 4, and a push plate 9 is slidably connected in the storage bin 4. The push plate 9 is used to centrally push the fiber pieces in the storage bin 4 out of the discharge port 17 to prevent the fiber pieces from flying. A hydraulic telescopic rod 10 and a limit rod 11 are fixedly connected to the push plate 9, and the hydraulic telescopic rod 10 is controlled by a motor. The limit rod 11 is slidably connected in the limit groove 12, and the limit groove 12 and the hydraulic telescopic rod 10 are fixedly connected to the storage bin 4 through a support block 13. The storage bin 4 and the support block 13 are fixedly connected to the bottom plate 14, and the lower surface of the bottom plate 14 is fixedly connected to a support foot 15.

[0017] The air outlet of the blower 3 is fixedly connected with a filter screen 16 , and the filter screen 16 prevents the fibers in the storage bin 4 from flying into the blower 3 and blocking the blower 3 during the loosening operation.

[0018] The main opening roller 5 and the auxiliary opening roller 6 are arranged in a triangle, one end of the main opening roller 5 and the auxiliary opening roller 6 are rotatably connected to the opening bin 1, and the other end of the main opening roller 5 and the auxiliary opening roller 6 are connected to the output end of the motor. The rotation direction of the main opening roller 5 is opposite to that of the auxiliary opening roller 6, so that the fiber mass in the opening bin 1 is continuously rolled and transported in one direction; the rotation speed of the main opening roller 5 is slightly greater than that of the auxiliary opening roller 6, so as to achieve the purpose of tearing the fiber mass.

[0019] The storage bin 4 is provided with a discharge port 17 on one side away from the push plate 9 . The discharge port 17 is provided on the side of the storage bin 4 instead of on the bottom of the storage bin 4 to prevent small pieces of fiber from flying at the discharge port 17 when the blower 3 is working.

[0020] The hydraulic telescopic rod 10 includes a piston rod, which is fixedly connected to the push plate 9 , and is slidably connected in a rod body, which is fixedly connected to the support block 13 .

[0021] The side of the transition bin 7 away from the push plate 9 is an inclined surface, so that the small fiber pieces fall together or slide from the inclined surface into the storage bin 4, and the landing point is far away from the discharge port 17 to prevent scattering.

[0022] During the opening operation, the upper opening of the transition bin 7 is closed by the baffle 8, and the blower 3 is in the closed state. After the opening operation is completed, the upper opening of the transition bin 7 is opened by the baffle 8, and the fiber pieces fall directly or along the inclined surface of the transition bin 7 into the storage bin 4. At this time, the blower 3 is turned on to blow off the fiber pieces attached to the main opening roller 5 and the auxiliary opening roller 6, and the main opening roller 5 and the auxiliary opening roller 6 are closed, and the fiber pieces in the storage bin 4 are pushed out from the discharge port 17 by the push plate 9.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
