A flow-guiding duct device

Abstract

This invention discloses a flow-guiding air duct device, including an air inlet pipe with an internal flow-guiding air duct. An exhaust mechanism is located at the rear end of the air inlet pipe, which draws air outward to create a negative pressure within the air duct. A flow-guiding mechanism is installed inside the air inlet pipe to divert and guide the incoming airflow to the side walls of the air inlet pipe. The waste collection device proposed in this invention has a simple and compact overall structure, but it has two functions: first, it uses negative pressure to draw external lint or thread ends into the air inlet pipe, preventing the lint from scattering; second, after the airflow is diverted by the flow-guiding mechanism, when it reaches the location of electrical equipment outside the air inlet pipe, it can carry away heat from the pipe wall in contact with the electrical equipment, thus dissipating heat from the electrical equipment.

Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and in particular to a flow-guiding air duct device. Background Technology

[0002] The ring spinning machine is an important piece of machinery in the textile industry, playing a crucial role in the process of transforming roving into spinning yarn. In the spinning process, the drafting drive system is a key component, achieved through the different speeds of the front, middle, and rear rollers and the corresponding fiber clamping rollers. During the process of drawing the roving into spinning yarn using rollers of varying speeds, a large amount of lint or thread ends are generated and scattered throughout the yarn. This not only negatively impacts airflow but can also cause the yarn to become tangled and disordered, affecting spinning operations or resulting in yarn that does not meet usage requirements. Therefore, it is necessary to design a flow-guiding air duct device to remove the lint or thread ends generated during the roving-to-spinning process, preventing them from affecting the spinning operation. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a flow-guiding air duct device that uses negative pressure to draw the filaments generated during the spinning process into a waste collection device for collection, so as to prevent them from having a negative impact on the spinning process.

[0004] The technical solution of the present invention to achieve the above objectives is a flow-guiding air duct device, including an air inlet pipe with an internal flow-guiding air duct, and an exhaust mechanism provided at the rear end of the air inlet pipe, wherein the exhaust mechanism exhausts air outward to create a negative pressure in the internal air duct of the air inlet pipe.

[0005] The air inlet duct is equipped with a flow guiding mechanism to divert the airflow entering the air inlet duct and guide it to the two side walls inside the air inlet duct.

[0006] Furthermore, a filter mechanism is provided crosswise at the air inlet of the air inlet pipe to divide the air inlet pipe into a waste collection section and a heat dissipation section. Waste is filtered and intercepted by the filter mechanism and retained in the waste collection section of the air inlet pipe.

[0007] Furthermore, the filtration mechanism is a filter screen, which is inclined relative to the air inlet direction of the air inlet pipe.

[0008] Furthermore, electrical mounting positions for installing electrical equipment are provided on both sides of the heat dissipation section of the air inlet duct, and the electrical equipment is installed in the electrical mounting positions and contacts the outer wall of the air inlet duct.

[0009] Furthermore, an outlet is provided on one side wall of the waste collection section of the air inlet pipe, and a drawer for collecting waste is provided in the outlet, the drawer being located in front of the filter screen.

[0010] Furthermore, the two side walls of the heat dissipation section of the air inlet pipe are recessed and extend into the inner cavity.

[0011] Furthermore, the flow guiding mechanism is a flow guiding plate or a flow guiding block, the front end of the flow guiding plate and the flow guiding block is V-shaped or arc-shaped, and the rear end of the flow guiding plate and the flow guiding block extends in the direction of the exhaust mechanism.

[0012] Furthermore, the heat dissipation section of the air inlet duct has at least one side wall with a number of heat dissipation fins on its inner side, and the outer side wall of the heat dissipation section is in contact with the electrical equipment.

[0013] Furthermore, at least one side wall of the heat dissipation section of the air inlet duct is provided with a mounting hole, and the electrical equipment is provided with a plurality of heat dissipation fins, which extend into the inner cavity of the air inlet duct through the mounting hole.

[0014] Furthermore, the exhaust mechanism includes an exhaust box, an exhaust fan disposed inside the exhaust box, and an exhaust duct disposed on the exhaust box. The exhaust box is connected to the air inlet pipe, and the exhaust fan draws air out of the air inlet pipe and discharges it out through the exhaust duct.

[0015] Its advantages over existing technologies are:

[0016] The waste collection device proposed in this invention has a simple and compact overall structure, but it has two functions. First, it uses negative pressure to draw external lint or thread into the air inlet pipe to prevent the lint from scattering everywhere. Second, when the airflow reaches the location of the electrical equipment outside the air inlet pipe after being diverted by the flow guiding mechanism, it can carry away the heat from the pipe wall that is in contact with the electrical equipment, thus playing a role in heat dissipation for the electrical equipment.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Example 1 is a preferred embodiment, such as... Figure 1 As shown, a flow-guiding air duct device mainly includes an air inlet pipe 1 and a filter mechanism 2. An air duct is formed inside the air inlet pipe 1, and the filter mechanism 2 is horizontally arranged at the air inlet of the air inlet pipe 1, dividing the air duct inside the air inlet pipe 1 into two sections, namely a waste collection section and a heat dissipation section. At the rear end of the heat dissipation section (i.e., the rear end of the air inlet pipe 1), an exhaust mechanism 3 is provided. The exhaust mechanism 3 exhausts air from the air inlet pipe 1, so that a negative pressure channel is formed inside the air inlet pipe 1. External lint or thread ends will be sucked into the air inlet pipe 1 through the air inlet of the air inlet pipe 1, and the lint or thread ends will be filtered and intercepted by the filter mechanism 2 in the waste collection section.

[0030] refer to Figure 1 The exhaust mechanism 3 mainly includes an exhaust box 31 and an exhaust fan 32 installed inside the exhaust box 31. An exhaust duct 33 is provided on the exhaust box 31. The exhaust box 31 is connected to the heat dissipation section of the air inlet pipe 1. When the exhaust fan 32 draws the airflow out of the air inlet pipe 1, a negative pressure air duct will be formed in the inner cavity of the air inlet pipe 1. External lint or thread ends will be sucked into the air inlet pipe 1 along with the air. The airflow will pass through the waste collection section, the filter mechanism 2 and the heat dissipation section in sequence, and be discharged through the exhaust duct 33.

[0031] Electrical installation positions 13 are provided on both outer side walls of the heat dissipation section of the air inlet duct 1. The installed electrical appliances will come into contact with the outer side walls of the air inlet duct 1. When the airflow in the air inlet duct 1 passes through the heat dissipation section, it will carry away the heat on the inner wall and dissipate heat for the electrical equipment 6 that is in contact with the inner wall.

[0032] like Figure 1 As shown, in order to facilitate the collection of lint or thread ends, an outlet 11 is provided on one side wall of the waste collection section of the air inlet pipe 1. A drawer is provided in the outlet 11. The aforementioned filter mechanism 2 uses a filter screen 21, and the filter screen 21 is inclined relative to the air inlet direction of the air inlet pipe 1. The drawer is located in front of the filter screen 21. External lint or thread ends enter the waste collection section of the air inlet pipe 1 through the air inlet of the air inlet pipe 1. After being filtered and intercepted by the filter screen 21, the lint or thread ends will be blown into the drawer by the wind along the surface of the inclined filter screen 21. The inclined filter screen 21 can play a guiding role, making it easy for the flying lint to be concentrated in the drawer. After the drawer is full, it can be pulled out for processing, and then put back in its original position.

[0033] like Figure 2 and Figure 3 As shown, a flow guiding mechanism 4 is provided in the heat dissipation section of the air inlet duct 1. The flow guiding mechanism 4 is a flow guiding plate 41, which has various shapes. Its front end can be V-shaped or arc-shaped. When the airflow reaches the front end of the flow guiding plate 41, it will be diverted to both sides of the heat dissipation section of the air inlet duct 1 along the front end of the flow guiding plate 41 and guided to blow onto the side walls of the heat dissipation section. This facilitates the heat dissipation of the electrical equipment 6 that is in contact with the outer wall of the air inlet duct 1.

[0034] refer to Figure 2 and Figure 3 It should be noted that the rear end of the deflector plate 41 can extend towards the direction of the exhaust mechanism or not. If it extends, the overall length of the deflector plate 41 becomes longer, and the airflow can better contact the surface of the deflector plate 41. It has two functions: first, to improve the airflow diversion and deflection effect, and second, to increase the airflow velocity through the deflector channel and enhance the heat dissipation effect. If it does not extend, its overall shape is V-shaped or semi-circular, but the effect is slightly lower.

[0035] refer to Figure 1 The walls of the air inlet pipes 1 on both sides of the baffle plate extend into the inner cavity to form a recess, and the electrical equipment 6 is installed at this position. It has three functions: first, it can increase the heat dissipation area; second, it can make the two air ducts smaller, thereby increasing the airflow speed through the air ducts and enhancing heat dissipation; and third, when the electrical equipment 6 is installed at this position of the air inlet pipe 1, it can make the overall structure more compact and save installation space.

[0036] Example 2

[0037] refer to Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the flow guiding mechanism 4 is a flow guiding block 42. The front end of the flow guiding block 42 is V-shaped or arc-shaped. The flow guiding block 42 can be solid or hollow. Its function is the same as that of the flow guiding plate 41, but it has higher stability under the action of airflow. Its material is not specifically limited (it can be a metal part or a plastic part).

[0038] Of course, the flow guiding mechanism 4 can also be in other shapes; this is just a preferred embodiment.

[0039] Example 3

[0040] refer to Figure 6 The difference between Example 3 and Example 1 is that no filter mechanism is set at the air inlet of the air inlet pipe 1, and the outlet is also removed. The air inlet pipe 1 is drawn out by the exhaust mechanism, which creates negative pressure inside the air inlet pipe 1. The lint or thread ends from the outside are drawn into the air inlet pipe 1, pass through the air inlet pipe 1 and reach the exhaust box 31, and are finally discharged from the exhaust pipe 33. The exhaust pipe 33 can be connected to a collection mechanism to collect the discharged lint or thread ends.

[0041] Example 4

[0042] refer to Figure 7 The difference between Embodiment 4 and Embodiment 1 is that at least one inner wall of the heat dissipation section of the air inlet duct 1 is provided with a plurality of heat dissipation fins 5 (or both inner walls can be provided). The plurality of heat dissipation fins 5 are arranged along the air inlet direction and have two functions: first, they can increase the heat dissipation area and enhance the heat dissipation effect; second, they can play a role in guiding the airflow. The outer wall of the air inlet duct 1 is in contact with the electrical equipment 6. The heat emitted by the electrical equipment 6 will be transferred to the heat dissipation fins 5 through the duct wall. When the airflow passes through the location of the heat dissipation fins 5, it will carry away the heat on the heat dissipation fins 5.

[0043] Example 5

[0044] refer to Figure 8 The difference between Embodiment 5 and Embodiment 1 is that an installation hole 12 is provided on at least one side wall of the heat dissipation section of the air inlet pipe 1 (or on both sides of the air inlet pipe 1). The installation hole 12 is used to install electrical equipment 6.

[0045] like Figure 9As shown, compared with embodiment 3, the difference is that here a number of heat dissipation fins 5 are provided on the electrical device 6. When the electrical device 6 is installed, the heat dissipation fins 5 on the electrical device 6 will extend through the mounting hole 12 into the inner cavity of the air inlet pipe 1. The heat emitted by the electrical device 6 will be directly transferred to the heat dissipation fins 5. When the airflow passes through the heat dissipation fins 5, it will carry away the heat, and the heat dissipation effect will be better.

[0046] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
