Description

Technical Field

[0001] This utility model relates to the field of textile machinery, especially nonwoven fabric production machinery, and particularly to a lower drawing mechanism for nonwoven fabric spinning. Background Technology

[0002] Nonwoven fabric production involves bonding or weaving fiber raw materials into a fabric shape using physical or chemical methods, without the need for traditional textile weaving processes. In the nonwoven fabric production process, the spinning process requires a spinneret to inject the fiber raw materials into the melt to form filaments, and then an airflow drawing machine is used to stretch the filaments to a specified fineness before laying them into a fiber web.

[0003] In this process, the lower drafting mechanism is responsible for further stretching the extruded filaments to the target fineness and controlling the fiber alignment and web uniformity. However, during the stretching process, fibers may produce broken filaments, fly waste, and other residues. If these residues are not cleaned in time, they will accumulate on components such as the rollers and aprons of the drafting mechanism, forming a source of contamination. If fiber residues or dirt are present on the rollers and aprons of the lower drafting mechanism during high-speed operation, it will increase wear and tear on the components and reduce the service life of the equipment. Simultaneously, the accumulation of dirt can also cause malfunctions in the components, such as jamming and vibration, affecting the stability and production efficiency of the equipment. The cleanliness of the lower drafting mechanism directly affects the fiber stretching effect and web uniformity. If dirt or fiber residues are present inside the mechanism, it will lead to uneven fiber stretching, reduced web quality, and consequently affect the physical properties (such as strength and uniformity) and appearance quality of the nonwoven fabric.

[0004] Therefore, to avoid fiber residue causing contamination and to ensure the smooth operation of the drafting mechanism, cleaning of the lower drafting mechanism is necessary in actual production. Current cleaning methods typically require disassembling the lower drafting mechanism from the machine, cleaning it, and then reinstalling it. This disassembly, cleaning, and reassembly process is cumbersome, time-consuming, and requires extensive maintenance. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a lower drawing mechanism for nonwoven fabric spinning, which can be easily and quickly pulled out, making it convenient to clean and maintain the lower drawing mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a lower drawing mechanism for nonwoven fabric spinning, which is set on the frame of the spinning mechanism, including a lower drawing mechanism body, with side plates at both ends of the lower drawing mechanism body. The lower drawing mechanism for nonwoven fabric spinning includes at least one set of guide sliding mechanisms, each set of guide sliding mechanisms including a guide rail and a guide wheel; the guide rail is fixedly connected to the frame; the guide wheels are respectively disposed at both ends of the guide rail along its length direction, and respectively rotate and cooperate with the side plates at the corresponding ends of the lower drawing mechanism body. When the lower drawing mechanism body is pulled along the length direction of the guide rail, the guide wheels and the guide rail are in frictional cooperation.

[0007] In the above solution, the guide rail and guide wheel are designed so that the guide rail is fixed to the frame and the guide wheel rotates with the side plate of the lower drawing mechanism. When the lower drawing mechanism needs to be cleaned, the guide wheel is driven to rotate. Under the action of friction between the guide wheel and the guide rail, the guide wheel "walks" along the guide rail to realize the lateral entry and exit of the lower drawing mechanism relative to the frame. This simplifies the cleaning process of the lower drawing mechanism, eliminates the need for disassembly and assembly, and effectively improves cleaning efficiency.

[0008] Furthermore, the nonwoven fabric spinneret lower drafting mechanism includes two sets of guide sliding mechanisms, which are symmetrically arranged on both sides of the lower drafting mechanism body. That is, guide sliding mechanisms are designed on both sides of the lower drafting mechanism body, which helps to improve the stability and reliability of the lower drafting mechanism body when moving laterally.

[0009] Furthermore, in order to ensure the synchronization of the two guide sliding mechanisms during lateral entry and exit, the side plates of the lower drawing mechanism body are respectively provided with support transmission devices. The support transmission device includes a guide wheel shaft and guide wheel seats respectively disposed at both ends of the guide wheel shaft. The guide wheel seats are fixedly connected to the side plates, and the guide wheel shaft is rotatably disposed on the guide wheel seats corresponding to the same end side plates. The guide wheels corresponding to the same end side plates are synchronously driven to rotate through the guide wheel shaft.

[0010] Preferably, a power mechanism can be designed to provide power for the lateral movement of the lower drawing mechanism body. A power mechanism is also provided on either side plate at one end of the lower drawing mechanism body, and the output end of the power mechanism is connected to the guide wheel shaft. In this way, the power mechanism can provide torque for the rotation of the guide wheel shaft, making the movement of the lower drawing mechanism body relative to the guide rail more convenient and faster.

[0011] Furthermore, the power mechanism is a motor, and the output end of the motor is connected to a coupling. The coupling is connected to the guide wheel shaft. When the motor is working, the torque is transmitted to the guide wheel shaft through the coupling, which drives the guide wheel shaft to rotate. The guide wheel shaft then drives the guide wheel to rotate synchronously. The guide wheel and the guide rail are in frictional contact, and the guide wheel travels along the length of the guide rail, driving the main body of the lower drawing mechanism to move along the length of the guide rail.

[0012] The beneficial effects of this utility model are that the lower drafting mechanism for nonwoven fabric spinning provided by this utility model has a reasonable structural design, can be added to existing machinery, and can be easily and quickly pulled out from the whole machine, which facilitates timely cleaning of the lower drafting mechanism, avoids fiber residue causing pollution, ensures smooth operation of the drafting mechanism, and effectively simplifies the maintenance process and reduces the maintenance time required.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0018] like Figure 1 and Figure 2 The shown is a lower drafting mechanism for nonwoven fabric spinning, which is the preferred embodiment of this utility model. The lower drafting mechanism for nonwoven fabric spinning is mounted on the frame 3 of the spinning mechanism and includes a lower drafting mechanism body 9, with side plates 5 at both ends of the lower drafting mechanism body 9.

[0019] The nonwoven fabric spinning lower drafting mechanism includes two sets of guide sliding mechanisms, which are symmetrically arranged on both sides of the lower drafting mechanism body 9. Each set of guide sliding mechanisms includes a guide rail 1 and two guide wheels 2. In actual positioning and connection, the guide rail 1 serves as a stationary component and a positioning guide reference, and needs to be fixedly connected to the frame 3. The guide wheels 2 of the same set are located at both ends along the length of the guide rail 1 and are in contact with the guide rail 1. The contact pressure between the guide wheels 2 and the guide rail 1 needs to be reasonably designed to ensure that when the guide wheels 2 rotate, the friction between the guide wheels 2 and the guide rail 1 is sufficient to drive the lower drafting mechanism body 9 to move.

[0020] In the rotational engagement between the guide wheel 2 and the corresponding side plate 5 of the lower drawing mechanism body 9, to ensure the synchronization of the two guide sliding mechanisms during lateral movement, support transmission devices are respectively provided on the side plate 5 of the lower drawing mechanism body 9. In the selection and installation of the support transmission devices on the side plate 5, the support transmission device with motor 8 is the power side and can be designed to be installed on the outer side of the side plate 5 (the side away from the lower drawing mechanism body 9), while the support transmission device without motor 8 is the driven side and is designed to be installed on the inner side of its corresponding side plate 5 (the side closer to the lower drawing mechanism body 9).

[0021] Specifically, the support transmission device includes a guide wheel shaft 6 and guide wheel seats 4 disposed at both ends of the guide wheel shaft 6. The guide wheel seats 4 are fixedly connected to the side plate 5, and the guide wheel shaft 6 is rotatably mounted on the guide wheel seat 4 corresponding to the side plate 5 at the same end. The guide wheel 2 corresponding to the side plate 5 at the same end is synchronously driven to rotate through the guide wheel shaft 6.

[0022] In actual assembly, due to the weight of the lower drawing mechanism itself, a large force is required to move it laterally. Therefore, a power mechanism needs to be designed to provide power for the lateral movement of the lower drawing mechanism body 9. For example... Figure 1 and Figure 2 As shown, a motor 8 can be designed on one side plate 5. The output end of the motor 8 is connected to a coupling 7, which is then connected to the guide wheel shaft 6. When the motor 8 is working, it transmits torque to the guide wheel shaft 6 through the coupling 7, causing the guide wheel shaft 6 to rotate. The guide wheel shaft 6 then drives the guide wheel 2 to rotate synchronously. The guide wheel 2 is in frictional contact with the guide rail 1 and travels along the length of the guide rail 1, thus driving the lower drawing mechanism body 9 to move along the length of the guide rail 1.

[0023] This nonwoven fabric spinneret lower drafting mechanism features a rational structural design and can be directly modified from existing spinnerets. By adding a guide rail 1 to the frame 3 and a guide wheel 2, support transmission device, and power mechanism to the lower drafting mechanism, lateral movement of the lower drafting mechanism relative to the entire machine can be achieved conveniently and quickly, facilitating timely cleaning. When cleaning the lower drafting mechanism body 9 is required, the guide wheel 2 rotates. Under the friction between the guide wheel 2 and the guide rail 1, the guide wheel 2 "walks" along the guide rail 1, enabling the lower drafting mechanism body 9 to move laterally in and out of the frame 3. This simplifies the cleaning process, eliminates the need for disassembly and assembly, effectively cleans the lower drafting mechanism, prevents fiber residue from causing contamination, ensures smooth operation of the drafting mechanism, and effectively simplifies the maintenance process, reducing maintenance time.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
