Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a fiber pretreatment device for nonwoven fabric production. Background Technology

[0002] Existing nonwoven fabric production generally requires fiber opening pretreatment, which involves breaking large fiber clumps and blocks into smaller pieces and bundles. Opening reduces the scale of lateral fiber connections, creating conditions for further loosening to a single fiber state laterally.

[0003] A search revealed that CN222821736U discloses a fiber pretreatment device for nonwoven fabric production. This prior art involves repeatedly opening fiber clumps in an opening chamber, and using a blower to blow the opened fiber pieces into a storage silo to prevent them from adhering to the main and auxiliary opening rollers. An inclined transition silo keeps the fiber pieces away from the discharge port, and a pusher plate pushes the fiber pieces in the storage silo out of the discharge port.

[0004] Although the existing technology can fully loosen the fiber clumps and break them into small pieces, it is not possible to collect the small fiber pieces after they are pushed out directly from the discharge port. This makes it inconvenient to transfer the loosened fiber pieces to the next process for use. Moreover, when the pusher pushes out the fiber pieces, some fiber pieces tend to adhere to the pusher, which requires manual cleaning. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fiber pretreatment device for nonwoven fabric production, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a fiber pretreatment equipment for nonwoven fabric production, including a base, a storage bin on the base, a push plate attached to the right side of the inner wall of the storage bin, microholes evenly distributed on the push plate, and an air supply component on the base connected to the right end of the push plate, and the air supply component connected to a hydraulic telescopic rod on the base.

[0007] A collection component is provided on the left end of the outer wall of the storage bin;

[0008] The top of the storage silo is connected to a transition silo with a baffle assembly;

[0009] The top of the transition chamber is equipped with an opening chamber containing a blower and an opening roller assembly.

[0010] Preferably, the collection component includes a ventilated cloth bag, the opening of which is connected to an installation frame. Both the ventilated cloth bag and the installation frame are fitted and connected to the outer wall of the left end of the storage bin, and a fixing device for fixing the installation frame is provided on the base.

[0011] Preferably, a fixing frame is provided on the outer wall of the storage bin, and the left side of the fixing frame is in contact with the mounting frame.

[0012] Preferably, the fixing device includes support rods disposed at the front and rear ends on the left side of the base, with horizontally placed stop bars attached to the top of the support rods, and rotating shafts disposed on both sides of the stop bars, with bearing seats connected to both rotating shafts, and the bearing seats disposed on the base, and both sides of the stop bars being located on the left side of the mounting frame.

[0013] Preferably, the air supply assembly includes a box-type blower mounted on a base. The air outlet of the box-type blower is connected to a telescopic pipe, and the telescopic pipe is connected to an air supply hood. The air supply hood is located inside the storage silo and connected to the right end of the push plate. The air supply hood is connected to a hydraulic telescopic rod. The air inlet of the box-type blower is equipped with a filter screen.

[0014] Preferably, a through groove is provided at the right end of the storage bin.

[0015] This invention provides a fiber pretreatment device for nonwoven fabric production. Compared with the prior art, it has the following advantages:

[0016] 1. The fiber pretreatment equipment for nonwoven fabric production covers the left end of the storage bin with a ventilated cloth bag on the collection component, and then fixes the installation frame with a fixing device, so that the ventilated cloth bag is fixed. When the push plate pushes out the small fiber pieces to the left, they can be collected through the ventilated cloth bag. After collection, the ventilated cloth bag can be removed by rotating the stop bar, and the small fiber pieces can be transferred to the next process for use.

[0017] 2. The fiber pretreatment equipment for nonwoven fabric production pushes small fiber pieces into the ventilated bag to the left. Air can be supplied through the air supply component and blown to the left through the micropores to blow the small fiber pieces attached to the push plate into the ventilated bag, thereby saving labor. The whole process can be carried out continuously and is highly practical. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: A fiber pretreatment device for nonwoven fabric production includes a base 1, a storage bin 2 is provided on the base 1, a push plate 8 is attached to the right side of the inner wall of the storage bin 2, micro holes 9 are uniformly provided on the push plate 8, and an air supply component is connected to the right end of the push plate 8 on the base 1, and the air supply component is connected to a hydraulic telescopic rod 17 on the base 1, the hydraulic telescopic rod 17 is used to drive the push plate 8 to move to the left.

[0026] A collection component is provided on the left end of the outer wall of storage silo 2;

[0027] The top of the storage bin 2 is connected to a transition bin 3 with a baffle assembly 7. The baffle assembly 7 is the same as that disclosed in CN222821736U, and is rotatably connected to a baffle via a shaft. The baffle can rotate on the transition bin 3. The shaft is controlled by a motor.

[0028] The top of the transition chamber 3 is equipped with an opening chamber 4 containing a blower 5 and an opening roller assembly 6. The blower 5 and the opening roller assembly 6 are the same as those disclosed in CN222821736U. The blower 5 blows the opened fiber pieces in the opening chamber 4 into the storage chamber 2 to prevent the fiber pieces from adhering to the opening roller assembly 6. The opening roller assembly 6 includes a main opening roller and two auxiliary opening rollers, which are arranged in a triangle. The rotation direction of the main opening roller is opposite to that of the auxiliary opening rollers, so that the fiber clumps in the opening chamber 4 are continuously tumbling and conveyed in one direction. The rotation speed of the main opening roller is slightly greater than that of the auxiliary opening rollers, thereby achieving the purpose of tearing the fiber clumps.

[0029] The collection component includes a ventilated bag 10, the opening of which is connected to a mounting frame 11. Both the ventilated bag 10 and the mounting frame 11 are attached to the outer wall of the left end of the storage bin 2, and a fixing device for fixing the mounting frame 11 is provided on the base 1.

[0030] In order to position the mounting frame 11, a fixing frame 12 is provided on the outer wall of the storage bin 2, and the left side of the fixing frame 12 is in contact with the mounting frame 11.

[0031] The fixing device includes support rods 13 located at the front and rear ends on the left side of the base 1. The top of the support rods 13 is attached to a horizontally placed baffle 14. A rotating shaft 15 is provided on both sides of the baffle 14, and a bearing seat 16 is connected to both sides of the rotating shaft 15. The bearing seat 16 is located on the base 1. Both sides of the baffle 14 are located on the left side of the mounting frame 11, which prevents the mounting frame 11 from moving to the left, thereby fixing the mounting frame 11 and fixing the ventilation bag 10. When the collection is completed and it needs to be removed, the rotating shaft 15 is rotated to move the baffle 14 away from the support rod 13, so that it will not block the mounting frame 11, making it easier to assemble and disassemble the mounting frame 11 on the storage bin 2.

[0032] The air supply assembly includes a box-type blower 18 mounted on the base 1. The air outlet of the box-type blower 18 is connected to a telescopic pipe 19, and the telescopic pipe 19 is connected to the air supply hood 20 without affecting the movement of the air supply hood 20. The air supply hood 20 is located inside the storage bin 2 and is connected to the right end of the push plate 8. The air supply hood 20 is connected to a hydraulic telescopic rod 17. The push plate 8 is moved by moving the air supply hood 20. The air inlet of the box-type blower 18 is equipped with a filter screen 21 to prevent dust from entering during air extraction.

[0033] The second implementation differs from the first implementation in that a through groove 22 is provided at the right end of the storage bin 2, which facilitates the installation of the air supply hood 20 and the telescopic pipe 19.

[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0035] In use, the mounting frame 11 is placed on the left end of the storage bin 2, so that the ventilation bag 10 is also placed on the left end of the storage bin 2 until it is blocked by the fixing frame 12. Then, the stop bar 14 is rotated so that it falls on the support bar 13 to block the mounting frame 11, thus completing the fixing of the mounting frame 11. At this time, the push plate 8 is moved to the left to push the small fiber pieces in the storage bin 2 into the ventilation bag 10. Finally, the box blower 18 is turned on so that the high-speed airflow enters the air supply hood 20 under the conveying of the telescopic tube 19, and is blown out through the micro-holes 9, blowing the small fiber pieces attached to the left side of the push plate 8 into the ventilation bag 10. Because the ventilation bag 10 itself can ventilate, it will not cause the small fiber pieces in the ventilation bag 10 to fly around, thus completing the collection. Finally, it is removed and transferred to the next process for use.
