Abstract

This utility model relates to the field of polyester filament technology and discloses a dust removal device for a polyester filament texturing machine, including a dust removal box and a suction pipe, wherein the suction pipe is fixedly connected to one side of the dust removal box. This utility model, by setting a vibration mechanism, can start a motor when a large amount of dust is adsorbed on the filter element. The motor will drive the rotating rod, the extrusion block, and the extrusion rod to rotate. During the rotation of the extrusion rod, its surface will contact the inner wall of the extrusion groove. Under the influence of extrusion, the transmission frame will move downward, simultaneously driving the conical striking block to move downward. At this time, the tension spring is in a stretched state. Then, when the extrusion rod rotates to a point where it no longer contacts the inner wall of the extrusion groove, under the influence of extrusion, the tension force generated by the tension spring will drive the transmission frame and the conical striking block to move sharply upward. The conical striking block will strike the bottom of the positioning frame, causing the positioning frame to vibrate. The vibration force will be transmitted to the filter element, shaking off the dust adhering to the filter element, thus achieving the function of dust removal from the filter element.

Description

Technical Field

[0001] This utility model relates to the field of polyester filament technology, specifically to a dust removal device for a polyester filament texturing machine. Background Technology

[0002] Polyester filament is the commercial name for polyester fiber. Polyester filament is characterized by its resistance to chemicals and frequent washing, reducing fading and discoloration of clothing. During the texturing process, polyester filament requires dust removal to prevent lint from mixing in the air and affecting the normal breathing needs of workers.

[0003] A search revealed a Chinese patent document disclosing a dust removal device for a polyester filament texturing machine [Announcement No.: CN219897498U]. This device includes a central frame, with a water tank and a collection tank integrally formed with the central frame on both outer walls. It also includes a flow guide frame located at the bottom of the central frame, communicating with the interior of the central frame, and an extraction frame at its lower end, communicating with the interior of the flow guide frame. Finally, it includes an extraction pump located inside the central frame, with connecting pipes at both its inlet and outlet ends, connecting to the extraction frame and the collection tank respectively.

[0004] Existing dust removal equipment typically uses the suction power generated by an induced draft fan to collect lint and dust. However, during the collection process, the lint and dust adhere to the surface of the filter element, causing the suction power of the induced draft fan to decrease, making it unable to effectively collect the lint and dust, thus reducing the efficiency of dust removal. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal device for a polyester filament texturing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a polyester filament texturing machine, comprising a dust removal box and a suction pipe, wherein the suction pipe is fixedly connected to one side of the dust removal box, and an induced draft fan is fixedly connected to the other side of the dust removal box; a positioning frame is fixedly connected to the inner wall of the dust removal box, a filter element is installed on the inner wall of the positioning frame, two conical striking blocks are provided at the bottom of the positioning frame, an annular box is provided at the top of the positioning frame, the outer surface of the annular box is fixedly connected to the inner wall of the dust removal box, and several jet pipes are fixedly connected to the bottom of the annular box through a one-way pressure valve;

[0007] A vibration mechanism is fixedly mounted on the dust collection box and can control the conical striking block to intermittently strike the positioning frame to generate vibration.

[0008] A gas collection mechanism is fixedly mounted on the dust collection box.

[0010] Four tension springs are fixedly connected to the top of the transmission frame, and the top of the tension springs is fixedly connected to the bottom of the positioning frame.

[0011] Preferably, the gas collection mechanism includes a gas collection box fixedly connected to the inner wall of the dust collector box, an air inlet pipe fixedly connected to the bottom of the gas collection box through a first one-way valve, one end of the air inlet pipe extending through to one side of the dust collector box, a transmission pipe fixedly connected to one side of the gas collection box, and one end of the transmission pipe fixedly connected to one side of the annular box.

[0012] A push rod is fixedly connected to the bottom of the transmission frame. The bottom of the push rod extends through the inner wall of the air collection box and is fixedly connected to a push block.

[0013] Preferably, a piston plate is fixedly connected to the bottom of the push block, and the piston plate is made of rubber.

[0014] Preferably, a sliding rod is fixedly connected to the bottom of the positioning frame, and a sliding hole is provided on the top of the transmission frame to cooperate with the sliding rod.

[0015] Preferably, a bearing is provided on one side of the rotating rod, and the rotating rod is rotatably connected to the inner wall of the dust collection box through the bearing.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting a vibration mechanism, can start the motor when a large amount of dust is adsorbed on the filter element. The motor will drive the rotating rod, the squeezing block and the squeezing rod to rotate. During the rotation of the squeezing rod, its surface will contact the inner wall of the squeezing groove. Under the influence of squeezing, the transmission frame will move downward, and at the same time drive the conical striking block to move downward. At this time, the tension spring is in a stretched state. Afterward, when the squeezing rod rotates to the point where it no longer contacts the inner wall of the squeezing groove, under the influence of squeezing, the tension generated by the tension spring will drive the transmission frame and the conical striking block to move upward suddenly. The conical striking block will strike the bottom of the positioning frame, causing the positioning frame to vibrate. The vibration force will be transmitted to the filter element, shaking off the dust adhering to the filter element, thus achieving the function of dust removal from the filter element.

[0019] 2. This utility model, by setting up an air collection mechanism, enables the drive rod, drive block, and piston plate to move up and down simultaneously as the transmission frame moves up and down. When the piston plate moves upward, the air collection box is under negative pressure, and gas enters the air collection box through the inlet pipe. When the piston plate moves downward, the gas is compressed and enters the annular box through the transmission pipe. This cycle continues, intermittently injecting gas into the annular box. When the gas pressure in the annular box reaches the limit of the one-way pressure valve, gas will be intermittently ejected from the jet pipe. The compressed gas impacts the surface of the filter element, shaking off the adhering dust and thus improving the dust removal effect. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1 - Figure 6 As shown,

[0029] Example 1:

[0030] A dust removal device for a polyester filament texturing machine includes a dust collection box 1 and a suction pipe 2. The suction pipe 2 is fixedly connected to one side of the dust collection box 1, and an induced draft fan 3 is fixedly connected to the other side of the dust collection box 1. A positioning frame 4 is fixedly connected to the inner wall of the dust collection box 1, and a filter element 5 is installed on the inner wall of the positioning frame 4. Two conical striking blocks 6 are provided at the bottom of the positioning frame 4, and an annular box 7 is provided at the top of the positioning frame 4. The outer surface of the annular box 7 is fixedly connected to the inner wall of the dust collection box 1, and several jet pipes 8 are fixedly connected to the bottom of the annular box 7 through a one-way pressure valve.

[0031] The vibration mechanism is fixedly installed on the dust collector 1 and can control the conical striking block 6 to intermittently strike the positioning frame 4 to generate vibration.

[0032] The gas collection mechanism is fixedly installed on the dust collector box 1.

[0033] The vibration mechanism includes a motor 9 fixedly installed on one side of the dust collector 1. The output end of the motor 9 extends into the interior of the dust collector 1 and is fixedly connected to a rotating rod 10. An extrusion block 11 is fixedly connected to the surface of the rotating rod 10. An extrusion rod 12 is provided on one side of the extrusion block 11. A transmission frame 13 is provided at the bottom of the extrusion block 11. The bottom of the conical striking block 6 is fixedly connected to the top of the transmission frame 13. An extrusion groove 14 that cooperates with the extrusion rod 12 is opened at the top of the transmission frame 13.

[0034] Four tension springs 15 are fixedly connected to the top of the transmission frame 13, and the top of the tension springs 15 is fixedly connected to the bottom of the positioning frame 4.

[0035] In this embodiment, existing dust removal equipment typically collects lint and dust using the suction force generated by the induced draft fan 3. However, during the collection process, the lint and dust adhere to the surface of the filter element 5, causing the suction force of the induced draft fan 3 to decrease, making it unable to effectively collect the lint and dust, thus reducing the dust removal efficiency. Therefore, by setting a vibration mechanism, when a large amount of dust is adsorbed on the filter element 5, the motor 9 is started. The motor 9 drives the rotating rod 10, the extrusion block 11, and the extrusion rod 12 to rotate. During the rotation of the extrusion rod 12, its surface will contact the inner wall of the extrusion groove 14, such as... Figure 2 As shown, under the influence of compression, the transmission frame 13 will move downward, and at the same time drive the conical striking block 6 to move downward. At this time, the tension spring 15 is in a stretched state. Then, when the extrusion rod 12 rotates to a point where it does not contact the inner wall of the extrusion groove 14, under the influence of compression, the tension generated by the tension spring 15 will drive the transmission frame 13 and the conical striking block 6 to move upward suddenly. The conical striking block 6 will strike the bottom of the positioning frame 4, causing the positioning frame 4 to vibrate. The vibration force will be transmitted to the filter element 5, shaking off the dust adhering to the filter element 5, thus achieving the function of dust removal for the filter element 5.

[0036] It should be noted that, Figure 2 S1 is the moving trajectory of the compression rod 12, and S2 is the moving trajectory of the transmission frame 13.

[0037] The bottom of the positioning frame 4 is fixedly connected to a sliding rod 22, and the top of the transmission frame 13 is provided with a sliding hole 23 that cooperates with the sliding rod 22.

[0038] In this embodiment, by setting the sliding rod 22 and the sliding hole 23, when the extrusion rod 12 rotates and contacts the inner wall of the extrusion groove 14, the transmission frame 13 can only move downward along the trajectory of the sliding rod 22, thus limiting the movement trajectory.

[0039] A bearing 24 is provided on one side of the rotating rod 10, and is rotatably connected to the inner wall of the dust collection box 1 through the bearing 24.

[0040] In this embodiment, by setting the bearing 24, the rotating rod 10 can be supported, restricting it to rotating only around the bearing 24, and improving the smoothness of its rotation process.

[0041] The bottom of the dust collection box 1 is fixedly connected to a discharge pipe 25, and a collection tank 26 is threadedly connected to the surface of the discharge pipe 25.

[0042] In this embodiment, by setting up a discharge pipe 25 and a collection tank 26, the dust on the filter element 5 can be shaken off and fall into the collection tank 26 through the discharge pipe 25. Then, the collection tank 26 can be removed by twisting it, which facilitates the collection of dust.

[0043] Example 2:

[0044] Based on Embodiment 1, the vibration mechanism in this embodiment can shake off dust by vibration to achieve the function of dust removal. However, considering that many highly adhesive dusts are difficult to remove by vibration, the air collection mechanism in this application includes an air collection box 16 fixedly connected to the inner wall of the dust collection box 1. The bottom of the air collection box 16 is fixedly connected to an air inlet pipe 17 through a first one-way valve. One end of the air inlet pipe 17 extends through to one side of the dust collection box 1. A transmission pipe 18 is fixedly connected to one side of the air collection box 16. One end of the transmission pipe 18 is fixedly connected to one side of the annular box 7.

[0045] A push rod 19 is fixedly connected to the bottom of the transmission frame 13. The bottom of the push rod 19 extends through the inner wall of the air collection box 16 and is fixedly connected to a push block 20.

[0046] In this embodiment, by setting up a gas collection mechanism, when the transmission frame 13 moves up and down, it will drive the push rod 19, the push block 20 and the piston plate 21 to move up and down. When the piston plate 21 moves upward, the gas collection box 16 is under negative pressure, and the gas will enter the gas collection box 16 through the air inlet pipe 17. When the piston plate 21 moves downward, the gas is compressed and will enter the annular box 7 through the transmission pipe 18. This cycle continues, intermittently injecting gas into the annular box 7. When the gas pressure in the annular box 7 reaches the limit of the one-way pressure valve, the gas will be intermittently ejected from the jet pipe 8. The compressed gas will impact the surface of the filter element 5, shaking off the adhering dust, thereby improving the dust removal effect.

[0047] It should be noted that the first one-way valve is a valve that can only allow air to enter the air collection box 16, and the second one-way valve is a valve that can only allow air to be discharged from the air collection box 16.

[0048] A piston plate 21 is fixedly connected to the bottom of the push block 20. The piston plate 21 is made of rubber.

[0049] In this embodiment, by setting the piston plate 21, the sealing performance of the gas collecting box 16 can be improved, so that the gas collecting box 16 can complete the process of gas collection and compression, thereby improving the sealing performance.

[0050] Working principle: When a large amount of dust is adsorbed on the filter element 5, the motor 9 is started. The motor 9 will drive the rotating rod 10, the squeezing block 11, and the squeezing rod 12 to rotate. During the rotation of the squeezing rod 12, its surface will contact the inner wall of the squeezing groove 14, such as... Figure 2As shown, under the influence of compression, the transmission frame 13 will move downward, and at the same time drive the conical striking block 6 to move downward. At this time, the tension spring 15 is in a stretched state. Then, when the extrusion rod 12 rotates to a point where it does not contact the inner wall of the extrusion groove 14, under the influence of compression, the tension generated by the tension spring 15 will drive the transmission frame 13 and the conical striking block 6 to move upward suddenly. The conical striking block 6 will strike the bottom of the positioning frame 4, causing the positioning frame 4 to vibrate. The vibration force will be transmitted to the filter element 5, shaking off the dust adhering to the filter element 5, thus achieving the function of dust removal for the filter element 5.

[0051] As the transmission frame 13 moves up and down, it drives the push rod 19, the push block 20, and the piston plate 21 to move up and down. When the piston plate 21 moves upward, the air collection box 16 is under negative pressure, and the gas will enter the air collection box 16 through the air inlet pipe 17. When the piston plate 21 moves downward, the gas is compressed and enters the annular box 7 through the transmission pipe 18. This cycle continues, intermittently injecting gas into the annular box 7. When the gas pressure in the annular box 7 reaches the limit of the one-way pressure valve, the gas will be intermittently ejected from the jet pipe 8. The compressed gas will impact the surface of the filter element 5, shaking off the adhering dust, thereby improving the dust removal effect.

[0052] It should be noted that the induced draft fan 3 and the motor 9 are existing devices or equipment, or devices or equipment that can be implemented with existing technology, and the specific composition and principle of the power supply of the induced draft fan 3 and the motor 9 are clear to those skilled in the art, so they will not be described in detail here.
