Description

Technical Field

[0001] This application relates to the field of automotive carpet production technology, and more particularly to a fiber removal device. Background Technology

[0002] Ensuring the purity of fiber materials is crucial in the production of automotive carpets, as it directly affects the carpet's durability, aesthetics, and passenger comfort. The manufacturing process includes steps such as fiber opening, mixing, carding, web formation, and needle punching. Among these, fiber impurity removal is a key step in improving carpet quality. This step involves removing impurities from the fibers, such as paper scraps and yarn ends, to ensure the carpet's quality and performance.

[0003] Traditional fiber impurity removal methods typically involve beating the fibers and then using a blower to suck out the impurities. However, controlling the blower's suction power is a technical challenge, as excessive suction can cause fibers to be sucked out, potentially leading to blower blockage, while insufficient suction fails to effectively remove impurities. To avoid production interruptions and equipment maintenance caused by the blower sucking in fibers, the blower's outlet is usually positioned away from the fibers. However, this limits the removal of low-height impurities close to the fibers, thus affecting the overall impurity removal efficiency.

[0004] To improve the impurity removal efficiency in automotive carpet production, existing solutions involve using fans with varying suction power at multiple locations. While this method can improve impurity removal, it also increases production costs and operational complexity, reducing overall efficiency. Therefore, there is currently a lack of a device on the market capable of thoroughly and efficiently removing impurities from the fibers used in automotive carpet production. Utility Model Content

[0005] To address the problem of insufficient and inefficient fiber impurity removal in existing technologies, this application provides a fiber impurity removal device, the specific solution of which is as follows:

[0006] A fiber impurity removal device includes a dust removal mechanism, an impurity removal box with an inlet and an outlet, and a transmission mechanism fixed inside the impurity removal box. The transmission mechanism can transfer materials from the inlet to the outlet. A dust-beating mechanism is provided above the transmission mechanism, which can beat the materials transferred by the transmission mechanism.

[0007] The dust removal mechanism includes a first dust removal component and a second dust removal component. The first dust removal component includes a lifting mechanism and a horn tube installed in the impurity removal box via the lifting mechanism. The first end of the horn tube is horn-shaped and passes through the impurity removal box. A butterfly valve is fixedly installed at the second end of the horn tube. The second dust removal component is located between the first dust removal component and the transmission mechanism. The second dust removal component is fixedly connected to the impurity removal box via an installation component. The second dust removal component includes a connecting pipe and a dust removal pipe with a dust removal channel. The dust removal pipe is parallel to the width direction of the transmission mechanism. The first end of the dust removal pipe passes through the impurity removal box and is located outside the impurity removal box. The first end of the dust removal pipe is provided with an adjustment mechanism that can adjust the suction force at the dust removal channel. The second end of the dust removal pipe is closed. One end of the connecting pipe is connected to the dust removal pipe, and the other end of the connecting pipe faces the first end of the horn tube. The horn tube moves closer to or away from the connecting pipe via the lifting mechanism. The movement of the horn tube toward the connecting pipe can make the first end of the horn tube fit tightly with the other end of the connecting pipe.

[0008] Preferably, the horn tube is a three-way tube, a butterfly valve is fixed at the first horizontal end of the horn tube, the second horizontal end of the horn tube is closed, the lower end of the horn tube is horn-shaped, the lifting mechanism includes two cylinders, one cylinder is close to the first horizontal end of the horn tube, and the other cylinder is close to the second horizontal end of the horn tube, and the horn tube is installed in the impurity removal box through the two cylinders.

[0009] Preferably, both ends of the dust removal pipe are provided with adjustment mechanisms that can adjust the suction force at the dust removal channel, and both ends of the dust removal pipe pass through the impurity removal box and are located outside the impurity removal box.

[0010] Preferably, the adjusting mechanism includes an air outlet plate with a plurality of first air outlets and an adjusting plate with a plurality of second air outlets. The air outlet plate is fixed to one end of the dust removal pipe, and the adjusting plate is movably connected to the air outlet plate. The adjusting plate can rotate relative to the air outlet plate, and the rotation can make the first air outlet and the second air outlet at least partially overlap to form a connection.

[0011] Preferably, a rotating shaft is fixed at the center of the air outlet plate, and a rotating hole is provided at the center of the adjusting plate. The rotating shaft passes through the rotating hole and is threadedly connected to the knob. Tightening the knob can fix the adjusting plate.

[0012] Preferably, the first air outlet and the second air outlet correspond one-to-one and have the same shape and size.

[0013] Preferably, the assembly further includes a feed hopper, a carding roller, and an opening roller. The feed hopper is connected to the feed inlet of the impurity removal box via a connecting channel. The carding roller is fixedly mounted at one end of the connecting channel near the feed hopper, and the opening roller is fixedly mounted at the other end of the connecting channel near the feed inlet.

[0014] Preferably, a sealing ring is fitted onto the end of the connecting pipe facing the horn tube, and the sealing ring is securely connected to the connecting pipe by a clamp.

[0015] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0016] 1. The first dust removal component can be close to or far away from the second dust removal component, that is, the horn tube is driven by the lifting mechanism to be close to or far away from the connecting tube. With this setting, only one air-guiding mechanism needs to be connected to the end of the horn tube with a butterfly valve, so that dust can be sucked at different suction forces at the far end and near end of the transmission mechanism, so as to achieve full and efficient removal of impurities from the fibers.

[0017] 2. On the one hand, when the horn tube is far from the connecting pipe, it is far from the transmission mechanism. The connected air-guiding mechanism provides a large suction force, ensuring that the material is not sucked out, while powerfully removing the impurities raised by the beating mechanism. At the same time, the horn tube is equipped with a butterfly valve, which can make coarse adjustments to the suction force. On the other hand, when the horn tube is close to the connecting pipe until it is tightly attached to the connecting pipe, the horn tube and the connecting pipe are connected. At this time, the air inlet is the dust removal channel of the dust removal pipe. The dust removal pipe is close to the transmission mechanism, which is convenient for removing low-height impurities that are close to the material. The dust removal pipe is equipped with an adjustment mechanism, which can precisely adjust the suction force at the dust removal channel to avoid the material being sucked in due to excessive suction force.

[0018] 3. The horn tube is a three-way tube with two cylinders driving it at both ends in the horizontal direction, which enhances the fixing effect of the horn tube to adapt to frequent movement and prevent the horn tube from becoming loose and falling off.

Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] See also Figure 1 A fiber impurity removal device includes a dust removal mechanism 2, an impurity removal box 1 with an inlet and an outlet, and a transmission mechanism 11 fixed in the impurity removal box 1. The transmission mechanism 11 can be a conveyor belt. The transmission mechanism 11 can transmit materials from the inlet to the outlet. A dust-slapping mechanism 3 is provided above the transmission mechanism 11. The dust-slapping mechanism 3 can pat the materials transmitted by the transmission mechanism 11.

[0028] See Figure 1 and Figure 2The dust removal mechanism 2 includes a first dust removal component 21 and a second dust removal component 22. The first dust removal component 21 includes a lifting mechanism 212 and a horn tube 210 installed in the dust removal box 1 via the lifting mechanism 212. The lifting mechanism 212 is fixedly mounted in the dust removal box 1, and its movable end is fixedly connected to the horn tube 210. The first end of the horn tube 210 is horn-shaped and passes through the dust removal box 1. A butterfly valve 211 is fixedly mounted on the second end of the horn tube 210. The second dust removal component 22 is located between the first dust removal component 21 and the transmission mechanism 11. The second dust removal component 22 is fixedly connected to the dust removal box 1 via a mounting component. The second dust removal component 22 includes a connecting pipe 220 and a dust removal pipe 221 with a dust removal channel 223. The pipe 221 is parallel to the width direction of the transmission mechanism 11, which is the transverse direction of the transmission mechanism 11 perpendicular to the direction of the conveyor belt movement, i.e., from one side of the conveyor belt to the other side. The first end of the dust removal pipe 221 passes through the impurity removal box 1 and is located outside the impurity removal box 1. The first end of the dust removal pipe 221 is provided with an adjustment mechanism 224 that can adjust the suction force at the dust removal channel 223. The second end of the dust removal pipe 221 is closed. One end of the connecting pipe 220 is connected to the dust removal pipe 221, and the other end of the connecting pipe 220 faces the first end of the horn pipe 210. The horn pipe 210 moves closer to or away from the connecting pipe 220 through the lifting mechanism 212. The movement of the horn pipe 210 toward the connecting pipe 220 can make the first end of the horn pipe 210 fit tightly with the other end of the connecting pipe 220. When performing dust removal, simply connect a drafting mechanism to one end of the horn tube 210 equipped with a butterfly valve 211 to perform dust removal with different suction forces at the far and near ends of the transmission mechanism 11.

[0029] See also Figure 1 and Figure 2 The horn tube 210 is a three-way pipe. A butterfly valve 211 is fixed at the first horizontal end of the horn tube 210, and the second horizontal end of the horn tube 210 is closed. The lower end of the horn tube 210 is horn-shaped. The lifting mechanism 212 includes two cylinders. One cylinder is close to the first horizontal end of the horn tube 210, and the other cylinder is close to the second horizontal end of the horn tube 210. The horn tube 210 is installed in the impurity removal box 1 through the two cylinders.

[0030] Specifically, both ends of the dust removal pipe 221 are provided with adjustment mechanisms 224 that can adjust the suction force at the dust removal channel 223, and both ends of the dust removal pipe 221 pass through the impurity removal box 1 and are located outside the impurity removal box 1.

[0031] See also Figure 3 and Figure 4The adjustment mechanism 224 includes an air outlet 224-a with a plurality of first air outlets 224-c and an adjustment plate 224-b with a plurality of second air outlets 224-d. The air outlet 224-a is fixed to one end of the dust removal pipe 221. The adjustment plate 224-b is movably connected to the air outlet 224-a. The adjustment plate 224-b can rotate relative to the air outlet 224-a, and the rotation can cause the first air outlets 224-c and the second air outlets 224-d to at least partially overlap and form a connection.

[0032] See also Figure 4 A rotating shaft is fixed at the center of the air outlet plate 224-a, and a rotating hole is provided at the center of the adjusting plate 224-b. The rotating shaft passes through the rotating hole and is threadedly connected to the knob. Tightening the knob can fix the adjusting plate 224-b.

[0033] See also Figure 4 The first air outlet 224-c and the second air outlet 224-d correspond one-to-one and have the same shape and size.

[0034] See also Figure 1 The fiber impurity removal device also includes a feed hopper 4, a carding roller 5, and an opening roller 6. The feed hopper 4 is connected to the feed inlet of the impurity removal box 1 through a connecting channel 41. The carding roller 5 is fixedly installed at one end of the connecting channel 41 near the feed hopper 4, and the opening roller 6 is fixedly installed at the other end of the connecting channel 41 near the feed inlet. The carding roller 5 can first card the material, which helps the opening roller 6 to open the material. The opened material is easier to beat and vacuum in subsequent processes, which helps to improve the beating and dust removal effect.

[0035] See also Figure 2 A sealing ring 222 is fitted onto one end of the connecting pipe 220 facing the horn pipe 210, and the sealing ring 222 is fastened to the connecting pipe 220 by a clamp.

[0036] During the impurity removal process, one end of the butterfly valve 211 on the horn tube 210 is connected to the induced draft mechanism, and the material is transported by the transmission mechanism 11. The material here is mainly fibrous material. During the process of material transfer from the inlet to the outlet, the dust-beating mechanism 3 regularly beats the material to raise impurities. While the dust-beating mechanism 3 beats the material, the transmission mechanism 11 pauses its movement. At this time, the horn tube 210 moves away from the connecting pipe 220, and the induced draft mechanism provides a large suction force to forcefully remove the impurities raised by the beating mechanism. Based on actual feedback, the butterfly valve 211 can be adjusted to coarsely regulate the suction force. After the dust-beating mechanism 3 completes its beating, the horn tube 210 moves closer to the connecting pipe 220 until it is in close contact with the connecting pipe 220. At this time, the horn tube 210 is connected to the connecting pipe 220, and the transmission mechanism 11 continues to move. The material passes through the dust removal channel 223 of the dust removal pipe 221, removing low-height impurities close to the material. The dust removal pipe 221 is equipped with an adjustment mechanism 224, which can precisely adjust the suction force at the dust removal channel 223 based on actual feedback to avoid excessive suction force from sucking in material. After two dust removal processes, the material finally leaves through the outlet.

[0037] In summary, the fiber cleaning device of this application can connect a single air intake mechanism to the end of the horn tube 210 where the butterfly valve 211 is located, thus adapting to different suction levels at the far and near ends of the transmission mechanism. Therefore, the fiber cleaning device of this application can solve the problem of insufficient and inefficient fiber cleaning in the prior art.
