Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing equipment, and in particular to an airflow beater unit and a rope-shaped air beater. Background Technology

[0002] The softening and fluffing treatments for textile fabrics play a crucial role in improving wearing comfort, enhancing fabric feel and appearance, and increasing durability. Currently, the commonly used treatment methods fall into two main categories: chemical softening and mechanical softening. Chemical softening requires a large amount of chemical auxiliaries and generates wastewater, causing environmental pollution and impacting the health of operators. Therefore, mechanical softening is currently the mainstream treatment method.

[0003] An airflow softening machine (also known as an air beater) is a form of mechanical softening. Based on aerodynamic principles, it uses air as power, employing a strong airflow under high temperature and pressure to knead and beat the fabric, ultimately making it softer to the touch and more fluffy and elastic in appearance. Specifically, an airflow softening machine includes a fabric inlet pipe with beating plates on both sides. A fan and air valves are connected to the inlet pipe. The air valves change the direction of the high-speed airflow within the inlet pipe, causing the fabric to repeatedly beat against the beating plates at both ends, thus making the fabric softer and fluffier.

[0004] However, this type of equipment still has the following drawbacks:

[0005] 1. The current equipment adopts a structure with two fans (upper inlet fan and lower inlet fan) arranged in one inlet pipe. The two fans have opposite output directions. The opening and closing of the two fan outlets are controlled by air valves to achieve the change of air direction. However, the single-pipe dual-fan setting makes the equipment larger in size.

[0006] 2. The high-speed airflow needs to be heated before entering the fabric inlet pipe to treat the fabric in the form of hot airflow. After the airflow rushes out of the fabric inlet pipe, it is discharged (or sucked away by the dust removal pipe, or led out by the guide pipe), resulting in a waste of heat.

[0007] 3. Airflow softening machines are divided into rope-type and flat-width types according to the state of the fabric during conveying. Flat-width machines are slow and inefficient. At the same time, the change of air direction in the fabric feeding pipe is achieved by limit switches. The use of limit switches causes warp and weft tension on the fabric surface, resulting in poor softening effect and easy damage to the fabric.

[0008] Therefore, this case is brought. Utility Model Content

[0009] One of the objectives of this invention is to provide an airflow beater unit that simplifies the equipment and improves energy efficiency by optimizing the equipment structure.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows:

[0011] An airflow beating unit includes a vortex fan, a hollow fabric inlet pipe with openings at both ends, beating plates installed at both ends of the fabric inlet pipe, and a hopper located below the beating plates, with a guide plate provided between the hopper and the opening end of the fabric inlet pipe.

[0012] The inlet pipe includes a middle section pipe and side section pipes located at both ends of the middle section pipe. The middle section pipe includes a middle outer pipe and a middle inner pipe. The middle outer pipe is a T-shaped tee pipe, including horizontal ports A and B and a vertical pipe C. Ports A and B are connected to the side section pipes on both sides, and the lower end of pipe C is connected to the outlet of the vortex fan. The middle inner pipe is horizontally fixed between ports A and B of the middle outer pipe, and the diameter of the middle inner pipe is smaller than that of the middle outer pipe, so that the airflow entering from pipe C can flow to port A or port B. Pipe C is equipped with a rotating shaft, and a guide vane is fixed on the rotating shaft. After the guide vane is flipped, it can contact the side wall of pipe C on one side of the rotating shaft. The middle part of the outer wall of the middle inner pipe is equipped with an isolation plate, which extends upward to the inner wall of the middle outer pipe and downward to the rotating shaft.

[0013] It includes a shaft drive unit for driving the shaft to drive the guide vane to reciprocate in rotation.

[0014] Furthermore, the rotating shaft drive unit includes a cylinder and a linkage lever, wherein the cylinder seat end of the cylinder is rotatably connected to the external frame, the piston end of the cylinder is rotatably connected to one end of the linkage lever, and the other end of the linkage lever is rotatably connected to the rotating shaft.

[0015] Furthermore, there are two feed pipes arranged in parallel, and there is only one vortex fan. A Y-shaped connecting pipe is provided between the air outlet of the vortex fan and the C-pipe of the two feed pipes. The lower end of the Y-shaped connecting pipe is connected to the air outlet of the vortex fan, and the two forks at the upper end are respectively connected to the lower end of the C-pipe.

[0016] The second objective of this utility model is to provide a rope-shaped air beater, including a frame, an airflow beater unit installed inside the frame, a heating module provided at the air inlet of the vortex fan, the heating module being located below a guide plate, the guide plate being a grid structure, and a cover plate covering the outside of the frame.

[0017] Furthermore, a dust removal system is provided outside the cover plate. The dust removal system includes a dust suction port, a dust suction pipe, and a dust suction fan. The dust suction port is located on one side of the beater plate, and the beater plate adopts a grid structure. One end of the dust suction pipe is connected to the dust suction port, and the other end is connected to the air inlet of the dust suction fan. Several removable first filters are provided inside the dust suction pipe.

[0018] Furthermore, the vortex fan is equipped with a removable second filter screen on the air inlet side. The air is first filtered by the second filter screen and then heated by the heating module before entering the vortex fan.

[0019] Furthermore, there are several airflow tapping units installed in the frame, and the several airflow tapping units are arranged in parallel and / or in a straight line and / or in a stacked arrangement.

[0020] The cover plate is provided with a main feed inlet and a main discharge outlet. At the same time, the cover plate is provided with a sub-feed inlet and a sub-discharge outlet above the hoppers at both ends of each feed pipe. Guide rollers are provided between the main feed inlet and the adjacent sub-feed inlet, between the adjacent sub-discharge outlet and the sub-feed inlet, and between the main discharge outlet and the adjacent sub-discharge outlet.

[0021] Furthermore, a weighing sensor is installed at the hopper. The weighing sensor provides feedback on whether the weight of the fabric accumulated in the hopper exceeds or falls below a threshold, thereby controlling the cylinder to change the flip angle of the guide vane and thus switch the direction of airflow in the fabric inlet pipe.

[0022] Furthermore, the cover plate is provided with an observation window.

[0023] Furthermore, a cooling module is provided on the main discharge port side for cooling the output fabric.

[0024] The advantages of this utility model are:

[0025] 1. The structure of the air valve was redesigned so that only one fan is needed in each airflow beater unit to achieve the change of airflow direction. Furthermore, by setting a Y-type connecting pipe, only one fan is needed in each airflow beater unit. By increasing the fan power, the fabric beater process of two fabric inlet pipes can be realized, which greatly simplifies and optimizes the equipment.

[0026] 2. The heating module is placed inside the cover plate, which reduces heat loss. At the same time, the air inlet of the vortex fan with heating module is located below the grid-type guide plate, which can draw back part of the hot airflow sprayed from the inlet pipe for recycling, thus reducing energy consumption.

[0027] 3. A filter screen is installed on the outside of the heating module to filter out impurities in the airflow entering the fabric inlet duct. At the same time, several filter screens are installed in the dust removal system to filter out impurities in the airflow sprayed from the fabric inlet duct. Preferably, the air intake of the dust removal system is located on one side of the beater plate. The beater plate adopts a grid structure. The dust generated by the fabric hitting the beater plate can drift to the air intake of the dust removal system through the grid holes on the beater plate, thereby improving the dust removal efficiency.

[0028] 4. Multiple airflow tapping units can be set in the frame to extend the fabric processing path and increase the finishing time to meet the needs of different fabrics. At the same time, the temperature of the heating module of different airflow tapping units can be set differently, so that the airflow temperature of different airflow tapping units is different, so as to carry out fine tapping and softening treatment on the fabric; it can provide a variety of process options and increase the applicability of the equipment.

[0029] 5. The fabric transfer method of this equipment is rope-like, which has a good soft effect and high efficiency. Combined with the control of the air valve by the weighing sensor, the radial tension on the fabric surface is eliminated, making it fluffy, soft and free from abrasion. Attached Figure Description

[0045] The present invention will be further described in detail below with reference to the embodiments. It should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" etc. indicated by the accompanying drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0046] This embodiment proposes a rope-shaped air beater, such as Figures 1 to 13 As shown, it includes a frame, and the frame is covered by a cover plate 13. The cover plate 13 contains two airflow beaters. The structure of the airflow beaters will be explained below.

[0047] refer to Figures 6 to 12 Similar to existing technologies, the airflow tapping unit includes a vortex fan 1, a hollow inlet pipe 2 with openings at both ends, tapping plates 3 installed at both ends of the inlet pipe 2, and a hopper 4 located below the tapping plates 3. A guide plate 5 is provided between the hopper 4 and the opening end of the inlet pipe 2. However, in this embodiment, only one vortex fan 1 is provided in one airflow tapping unit. As an improvement, this embodiment innovates the air valve in the inlet pipe 2 to achieve the switching of the direction of the airflow ejected by the vortex fan 1.

[0048] The structural innovations of the air valve are described in detail below. For example... Figure 9 As shown, the inlet pipe 2 includes a middle section pipe 201 and side sections pipe 202 located at both ends of the middle section pipe 201. Figure 11As shown, the middle section pipe 201 includes a middle section outer pipe 2012 and a middle section inner pipe 2011. The fabric 12 can enter from one side section pipe 202, pass through the middle section inner pipe 2011, and then enter the other side section pipe 202. The middle section outer pipe 2012 is a T-shaped tee pipe, including horizontal ports A and B and a vertical pipe C. Ports A and B are connected to the side section pipes 202 on both sides, respectively. The lower end of pipe C is connected to the air outlet of the vortex fan 1. The middle section inner pipe 2011 is horizontally fixed in the middle section outer pipe 2012 and is located between ports A and B. The diameter of the middle section inner pipe 2011 is smaller than that of the middle section outer pipe 2012, creating a gap between the middle section inner pipe 2011 and the middle section outer pipe 2012. This gap can serve as a flow channel, allowing the airflow entering from pipe C to flow to port A or port B. (Continue to refer to...) Figure 11 Pipe C is equipped with a rotating shaft 6, on which a guide vane 7 is fixed. After rotating, the guide vane 7 can contact one side wall of pipe C on either side of the rotating shaft 6. A partition plate 8 is provided in the middle of the outer wall of the inner section 2011, extending upwards to the inner wall of the outer section 2012 and downwards to the rotating shaft 6. The partition plate 8 divides the flow channel formed between the outer section 2012 and the inner section 2011 into two independent parts: one facing port A and the other facing port B. When the guide vane 7 rotates to the left and contacts the left side wall, the airflow entering from pipe C is guided by the guide vane 7 and ejected from port B along the flow channel. Figure 11 The airflow in the middle is ejected from port B; when the guide vane 7 rotates to the right and contacts the side wall on the right side, the airflow entering from pipe C will be guided by the guide vane 7 and ejected from port A along the flow channel.

[0049] like Figure 10 As shown, the rotating shaft 6 is connected to pipe C via a bearing, with a portion of the rotating shaft 6 exposed above pipe C. The airflow beater unit's rotating shaft 6 drive unit is used to drive the rotating shaft 6 to cause the guide vane 7 to reciprocate in rotation. In this embodiment, the rotating shaft 6 drive unit includes a cylinder 9 and a linkage lever 10. The cylinder seat end of the cylinder 9 is rotatably connected to the external frame, and the piston end of the cylinder 9 is rotatably connected to one end of the linkage lever 10. The other end of the linkage lever 10 is rotatably connected to the rotating shaft 6. Through the extension and retraction of the cylinder 9, the linkage lever 10 swings, causing the rotating shaft 6 to rotate, thereby achieving the reciprocating flipping of the guide vane 7 to the left or right.

[0050] refer to Figure 6Fabric 12 enters the left hopper 4, flows along the guide plate 5 into the fabric inlet pipe 2, then into the right hopper 4 and is output. A certain amount of fabric 12 is provided in hopper 4. When the airflow flows to the left in the fabric inlet pipe 2, it causes the fabric 12 to impact the left-side striking plate 3 and fall into the left hopper 4 along the guide plate 5. When the airflow flows to the right in the fabric inlet pipe 2, it causes the fabric 12 to impact the right-side striking plate 3 and fall into the right-side hopper 4 along the guide plate 5. This process is the same as existing equipment and will not be described in detail here. Figure 7 As shown, the fabric 12 is conveyed to the right in the fabric inlet pipe 2. Under the guidance of the guide vane 7, the airflow flows to the right along the flow channel in the fabric inlet pipe 2. At this time, the fabric 12 is driven to hit the beater plate 3 on the right side.

[0051] refer to Figure 9 or Figure 12 In this embodiment, each airflow beating unit is equipped with only one vortex fan 1, but two parallel fabric inlet pipes 2 are arranged. A Y-shaped connecting pipe 11 is provided between the air outlet of the vortex fan 1 and the C-pipes of the two fabric inlet pipes 2. The lower end of the Y-shaped connecting pipe 11 is connected to the air outlet of the vortex fan 1, and the two branches at the upper end are respectively connected to the lower end of the C-pipes. By increasing the fan power, the beating process of the fabric 12 in the two fabric inlet pipes 2 can be realized, which greatly simplifies and optimizes the equipment.

[0052] like Figure 6 , Figure 8 and Figure 9 As shown, the air inlet of the vortex blower 1 is equipped with a heating module 18, which is located below the guide plate 5. The guide plate 5 has a grid structure. Part of the airflow ejected from the fabric inlet pipe 2 can be drawn back into the heating module 18 through the guide plate 5 and then enter the vortex blower 1 for recycling. The airflow ejected from the fabric inlet pipe 2 has already been heated, and recycling reduces energy consumption. In addition, in this embodiment, the heating module 18 (i.e., the air inlet of the vortex blower 1), like the hopper 4, guide plate 5, and fabric inlet pipe 2, is wrapped inside the equipment by the cover plate 13, which reduces heat loss. However, it should be noted that this wrapping is not absolutely sealed; a certain gap needs to be left for fresh air to enter.

[0053] The conveying and beating process of fabric 12 generates a considerable amount of impurities, such as lint and dust. This embodiment also includes an external dust removal system. Figure 1 and Figure 2 As shown, the dust removal system includes a suction port 15, a suction pipe 16, and a suction fan 17. One end of the suction pipe 16 is connected to the suction port 15, and the other end is connected to the air inlet of the suction fan 17. Several removable first filters are installed inside the suction pipe 16. Meanwhile, as... Figure 8As shown, the suction port 15 is located on one side of the beat plate 3, and the beat plate 3 adopts a grid structure. Most of the dust generated by the fabric 12 hitting the beat plate 3 will float out from the gaps in the beat plate 3 and be sucked in by the suction port 15. Of course, some heat will be lost in this process, which is unavoidable.

[0054] In terms of dust removal, such as Figure 6 and Figure 8 As shown, in this embodiment, a removable second filter screen 19 is provided on the air inlet side of the vortex fan 1. The air is first filtered by the second filter screen 19 and then heated by the heating module 18 before entering the vortex fan 1.

[0055] like Figures 1 to 3 As shown, this embodiment has two airflow tapping units arranged side by side. However, in practice, there may be one or more airflow tapping units, and the multiple airflow tapping units may be arranged in parallel and / or in a straight line and / or in a stacked arrangement. This can be flexibly adjusted according to the customer, the actual site, and the fabric processing requirements.

[0056] like Figure 13 As shown, to facilitate the flow of fabric 12, this application provides the following configuration for the rope-shaped air beater: A main feed inlet 1301 and a main discharge outlet 1302 are provided on the cover plate 13. Simultaneously, above the hoppers 4 at both ends of each fabric inlet pipe 2, the cover plate 13 is provided with a secondary feed inlet 1303 and a secondary discharge outlet 1304. Guide rollers 14 are provided between the main feed inlet 1301 and its adjacent secondary feed inlet 1303, between the adjacent secondary discharge outlet 1304 and its secondary feed inlet 1303, and between the main discharge outlet 1302 and its adjacent secondary discharge outlet 1304. (Reference) Figure 6 and Figure 13 Fabric 12 is fed into the main feed port 1301, guided by the guide roller 14 and enters the sub-feed port 1303. It then falls into the hopper 4 on one side, passes through the guide plate 5, the feed pipe 2, and the hopper 4 on the other side, and is then output from the sub-discharge port 1304. It then enters the next sub-feed port 1303, and so on, until it is output from the last sub-discharge port 1304. After being guided by the guide roller 14, it is output from the main discharge port 1302.

[0057] In this embodiment, the timing of the change in airflow direction within the fabric inlet pipe 2 is determined based on the remaining amount of fabric 12 in the hopper 4. If the remaining amount of fabric 12 on one side is insufficient, the fabric 12 striking the beater plate 3 on the other side may lack sufficient force or even fail to strike. In this embodiment, a weighing sensor is installed at the hopper 4. The weighing sensor provides feedback on whether the weight of the fabric 12 accumulated in the hopper 4 exceeds or falls below a threshold, thereby controlling the cylinder 9 to change the rotation angle of the guide vane 7, thus switching the airflow direction within the fabric inlet pipe 2. Figure 6For example, suppose the airflow is to the right at this time, causing the fabric 12 in the left hopper 4 to be blown to the right and enter the right hopper 4. This causes the weight of the fabric 12 in the left hopper 4 to decrease and the weight of the fabric 12 in the right hopper 4 to increase. When the weight of the fabric obtained by the weight sensor in the left hopper 4 is lower than the threshold or the weight of the fabric obtained by the sensor in the right hopper 4 is higher than the threshold, the guide vane 7 will move to reverse the airflow direction.

[0058] like Figure 1 As shown, in this embodiment, an observation window 1305 is provided on the cover plate 13 to facilitate workers to observe the inside of the equipment, especially the situation at the tapping plate 3 and the hopper 4.

[0059] Furthermore, this embodiment also includes a cooling module (not shown in the figure) on the side of the main discharge port 1302, which is used to cool the output fabric 12 for convenient subsequent finishing.

[0060] The above embodiments are only used to explain the concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
