Description

Technical Field

[0001] This solution belongs to the field of cleaning equipment, specifically involving a cleaning device for textile air conditioning sandproof windows. Background Technology

[0002] In the textile production process, textile workshops have strict requirements for dust control. If dust adheres to the fabric surface, it can easily form defects and color differences, damaging the appearance of the finished product. Currently, the fresh air windows of textile air conditioners are located on the first floor of the workshop and are adjacent to the road. Dust generated by passing vehicles can easily be directly drawn into the air-conditioned room, causing fresh air pollution. During sandstorms, the filter-less fresh air windows need to be manually closed, which is not only cumbersome but also results in a delay in intercepting dust. Therefore, sand-proof windows are needed to solve this problem.

[0003] A smart sandproof window for textile air conditioning is disclosed in the existing publication (announcement) number CN120759523A, including a sandproof frame, filter cloth, airflow guiding mechanism, airflow sensor, replacement mechanism and controller. The filter cloth is placed inside the sandproof frame; the airflow guiding mechanism is used to adjust the ambient wind pressure on the filter cloth; the airflow sensor is used to monitor the airflow size in the connecting pipe; the replacement mechanism is used to replace the filter cloth; the replacement mechanism includes a driving component, a drive shaft and a driven shaft, the drive shaft and the driven shaft cooperate, the driven shaft is rotatably disposed at the upper end of the sandproof frame, the drive shaft is rotatably disposed at the lower end of the sandproof frame, one end of the filter cloth is fixedly connected to the drive shaft, and the other end is wound and fixed on the driven shaft, the driving component is used to drive the drive shaft to rotate.

[0004] For example, although the intelligent sand-proof window for textile air conditioning previously proposed by the applicant has solved the problem of dust pollution in fresh air to a certain extent, in the actual operation of the sand-proof window, when the drive component drives the active shaft to roll up the used filter cloth, a large amount of dust trapped on the surface of the filter cloth has not been effectively cleaned and is directly rolled onto the active shaft along with the filter cloth. This will cause the dust to be dispersed again during the rolling process, and will also affect the normal unfolding and rolling of the filter cloth, making it difficult to achieve the purpose of efficient, clean and automated sand and dust prevention. Utility Model Content

[0005] The purpose of this solution is to provide a cleaning device for textile air conditioning sandproof windows to solve the problem of existing sandproof windows not cleaning the filter cloth.

[0006] To achieve the above objectives, this solution provides a cleaning device for a textile air conditioner sandproof window, including a filter cloth, and further including a cleaning device for cleaning the filter cloth, the cleaning device comprising: The suction nozzle is located on the side of the filter cloth closest to the outside, with the air inlet of the nozzle facing the filter cloth, and is used to clean the filter cloth when it is rolled up; the suction nozzle is connected to a negative pressure source through a pipe. A drive assembly for driving the suction nozzle to reciprocate along the width direction of the filter cloth.

[0007] The principle and effect of this solution are as follows: by setting a suction nozzle on the side of the filter cloth near the outside, the negative pressure source causes the suction nozzle to generate suction force, which, together with the drive component, drives the suction nozzle to move back and forth along the width of the filter cloth, so as to thoroughly clean the surface of the filter cloth during the winding process, thereby avoiding the problem of secondary dust dispersion when the filter cloth is wound up.

[0008] Furthermore, the driving component is a sliding guide rail, and the suction nozzle is disposed on the slider of the sliding guide rail; the negative pressure source is a vacuum cleaner.

[0009] The principle and effect of this solution are as follows: the vacuum cleaner provides negative pressure to generate suction force in the nozzle, and the slider of the sliding guide rail drives the nozzle to move along the width of the filter cloth, and the surface of the filter cloth near the outside is cleaned repeatedly during the winding process.

[0010] Furthermore, the driving component is a reciprocating lead screw, and a drive motor is coaxially and fixedly connected to the rotating shaft of the reciprocating lead screw. A slider is provided on the threaded groove of the reciprocating lead screw, and the suction nozzle is fixedly mounted on the slider. A guide rod is fixedly connected to the slider.

[0011] The principle and effect of this solution are as follows: During the filter cloth winding process, the drive motor drives the reciprocating screw to rotate, and the threaded groove drives the slider and the suction nozzle fixed on the slider to move. The guide rod makes the slider and the suction nozzle reciprocate, thereby cleaning the surface of the filter cloth near the outside repeatedly.

[0012] Furthermore, the outer wall of the reciprocating screw abuts against the side of the filter cloth closest to the outside, and the filter cloth is wrapped around the outer periphery of the reciprocating screw, so that the filter cloth transitions from a vertical section to a horizontal section after passing the reciprocating screw; both ends of the reciprocating screw are provided with inclined dust discharge plates, and one end of the dust discharge plate is attached to the edge of the filter cloth.

[0013] The principle and effect of this scheme are as follows: (1) During the process of rolling up the contaminated filter cloth and moving the new filter cloth downward to the window, since the filter cloth is set on the window in a vertical hanging state, it will fall off due to vibration when the filter cloth moves, and the cotton dust and dust on it will fall downward. In addition, since the suction nozzle is moving back and forth, its cleaning area is limited by the travel range and cannot cover and adsorb the entire surface during the movement of the filter cloth, resulting in some dust falling vertically to the ground due to gravity after it is detached from the filter cloth. (2) In this scheme, the reciprocating screw is set at the turning point where the filter cloth transitions from the vertical section to the horizontal section, so that its outer wall is in close contact with the side of the filter cloth that is close to the outside, which is used to support and guide the movement of the filter cloth. More importantly, the threaded guide groove on the surface of the reciprocating screw receives the cotton dust and dust that fall off the filter cloth during the movement of the filter cloth; and during the rotation of the reciprocating screw, it moves spirally to both ends of the screw along the threaded guide groove and is guided to the dust discharge plate, so that the dust slides down to the designated collection area instead of scattering on the ground.

[0014] Furthermore, it also includes a winding assembly, which includes a driven roller and a driving roller. The filter cloth is wound on the driven roller, and the free end of the filter cloth is fixed and wound on the driving roller. Both the driven roller and the driving roller are connected to a winding motor for driving their rotation. The reciprocating screw is located between the driven roller and the driving roller, and is close to the driving roller.

[0015] The principle and effect of this scheme are as follows: (1) The new filter cloth is wound on the driven roller. When the filter cloth needs to be replaced, the active roller is driven to rotate by the winding motor on the active roller, so that the old filter cloth is wound on the active roller and the new filter cloth is replaced on the window. (2) The reciprocating screw is arranged between the driven roller and the active roller and is close to the active roller. It is located on the last section of the path before the filter cloth is about to be wound. After the suction nozzle cleans the surface of the filter cloth in this area, the clean filter cloth is then wound by the active roller, and the dust that falls off is guided to both ends by the thread groove of the reciprocating screw and discharged through the dust discharge plate to avoid contaminating the wound part.

[0016] Furthermore, the filter cloth is located on the outside of the window, and louvers are provided on the inside of the window; it also includes a driving device for driving the driven roller and the active roller to move along the window direction, so that the filter cloth covers or moves away from the window; the driven roller and the active roller are both located on the driving device.

[0017] The principle and effect of this solution are as follows: When the dust content outdoors is low, the drive device moves the active roller and the driven roller away from the window, thereby moving the filter cloth away from the window. The inner side of the window (indoors) only has louvers, increasing the air intake. When the dust content outdoors is high, the drive device again moves the active roller and the driven roller towards the window, positioning them on the upper and lower sides of the window respectively, so that the filter cloth covers the outer side of the window, thus filtering dust and gas.

[0018] Furthermore, a honeycomb heat exchanger is provided on the side of the louvers closest to the interior.

[0019] The principle and effect of this solution are as follows: the honeycomb heat exchanger has a heat exchange area and a flow channel structure, which allows indoor and outdoor gases to come into contact when passing through the fluid in the heat exchanger, thereby achieving gas heat exchange and preventing the outdoor air temperature from being too high when entering the room; at the same time, the louver blade structure works in conjunction with the honeycomb heat exchanger to prevent dust in the outside air from entering the room.

[0020] Furthermore, the cleaning device also includes a cylinder and a rotary joint. The piston of the cylinder is fixedly connected to the free end of the guide rod. The exhaust port of the cylinder is connected to the air inlet of the rotary joint through an exhaust pipe. The air outlet of the rotary joint is coaxially rotatably connected to one end of the reciprocating screw. An air storage chamber is provided inside the reciprocating screw, and the air storage chamber is connected to the air outlet of the rotary joint. Several air jets are provided along the circumference of the reciprocating screw.

[0021] The principle and effect of this solution are as follows: By cooperating with the cylinder piston and guide rod, when the guide rod moves with the slider, the guide rod (equivalent to the piston rod) drives the cylinder piston to reciprocate, periodically compressing the gas in the cylinder chamber. The compressed gas discharged from the exhaust port is then introduced into the air storage chamber inside the reciprocating screw through the exhaust pipe and rotary joint, and ejected from the circumferentially distributed air jets. During the rotation of the reciprocating screw, the air jets rotate, and some of the air jets spray upwards or obliquely upwards onto the back of the filter cloth, creating an upward blowing effect on the adhering light impurities such as cotton dust. At this time, the suction nozzle can more efficiently suck away the impurities that have been lifted by the airflow, and this solution does not require an additional independent air source or blower, thus achieving a better cleaning effect on the filter cloth.

[0022] Furthermore, the jet nozzle is a flared jet nozzle, and a sealing ball for sealing the jet nozzle is provided inside the jet nozzle. The sealing ball is connected to a spring, and the free end of the spring is fixedly connected to the inner wall of the jet nozzle. The sealing ball is a ferromagnetic sealing ball. A magnetic fixing plate is provided on the vertical section of the filter cloth near the interior. A push switch is provided on the fixing plate. The trigger end of the push switch is provided with a wind receiving plate. The wind receiving plate is used to abut the trigger end of the push switch after being pushed by the airflow. The fixing plate, the push switch and the wind receiving plate are all inclined towards the filter cloth and are higher than the horizontal center line of the reciprocating screw.

[0023] The principle and effect of this scheme are as follows: (1) Due to the wear caused by hard particles such as sand embedded in the fiber gaps during long-term operation, the filter cloth will have damaged holes, which will allow dust to enter the textile workshop and need to be repaired before use. In this scheme, a normally closed sealing structure consisting of a sealing ball and a spring is set in the air jet. When the reciprocating screw rotates, the ferromagnetic sealing ball and the magnetic fixing plate are magnetically matched. The fixing plate attracts the sealing ball to move towards the fixing plate, thereby making the sealing ball away from the air jet and pulling the tension spring. The air jet opens and sprays out the air. When the filter cloth is intact, the sprayed air is blocked by the filter cloth or the air is too small to penetrate. The air receiving plate is not impacted by the air or the air is too small, so it will not resist the press switch. When the filter cloth has damaged holes, the air jet from the air jet will pass through the holes and act on the air receiving plate, pushing it to resist the trigger end of the press switch, thereby sending a filter cloth damage signal. This scheme can clean the filter cloth and detect whether the filter cloth is damaged by the air jet. (2) Because the sealing ball is magnetically engaged with the fixed plate, and the fixed plate, the push switch and the air receiving plate are all tilted towards the filter cloth and higher than the horizontal center line of the reciprocating screw. Only when the air jet is rotated to tilt towards the filter cloth, the fixed plate and the air receiving plate will the sealing ball be opened under the action of magnetic attraction, so that the air jet is opened. Only when the air jet is open at this position can the gas act on the filter cloth for dust removal and detection. At the same time, when the air jet moves away from this area with the screw, the magnetic force disappears or weakens, and the spring returns to push the sealing ball to close the air jet. This can prevent the air jet from being in the open state after it has rotated away from this position, so as to avoid the waste of gas in the gas storage chamber.

[0024] Furthermore, the wind-receiving plate is connected to a compression spring, and the free end of the compression spring is fixedly connected to the fixed plate; the push switch is electrically connected to an alarm.

[0025] The principle and effect of this solution are as follows: the wind-receiving plate is compressed, which overcomes the elastic force of the compression spring and triggers the push switch, thereby activating the alarm and sending out a warning signal.

[0026] Furthermore, the piston of the cylinder is connected to a tension spring, and the free end of the tension spring is fixedly connected to the inner wall of the cylinder; a one-way valve is provided on the exhaust pipe.

[0027] The principle and effect of this scheme are as follows: (1) The one-way valve is used to ensure that the gas in the exhaust pipe can only flow into the gas storage chamber in one direction, thus avoiding gas backflow. (2) During the filter cloth replacement process, when the winding motor stops and the active roller stops rotating, due to the inertia of the driven roller and the elasticity and flexibility of the filter cloth itself, the driven roller will continue to rotate slightly under the action of inertia, which will cause the new filter cloth wrapped on it to be released temporarily. The active roller cannot compensate for this displacement in time because it has stopped, which will cause the filter cloth tension between the two rollers to drop instantaneously and the filter cloth to become loose. This will not only affect the flatness of the filter cloth on the window, but may also cause wrinkles, deviations, or even uneven subsequent winding, thus affecting the sand and dust removal effect. In this design, during the normal winding of the filter cloth, the guide rod moves with the slider, driving the piston to move. This causes the tension spring to be stretched or compressed, cooperating with the piston and guide rod to compress the gas in the cylinder chamber and store elastic potential energy. When the winding motor stops and the drive roller stops rotating, the tension spring releases energy under the loss of external force constraint, pulling the piston and the connected guide rod back to their initial position. The return movement of the guide rod causes the slider to move in the opposite direction along the guide groove of the reciprocating screw, thereby driving the reciprocating screw to produce a slight rotation. Since the screw is located at the transition point of the filter cloth from the vertical section to the horizontal section, its slight rotation can apply compensating tension to the filter cloth, thereby counteracting the slack caused by the inertia of the driven roller, keeping the filter cloth at a moderate tension at all times, thus ensuring its flat fit on the window and avoiding wrinkles and misalignment.

[0031] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Example 1: Please see Figure 1 and Figure 2 This embodiment discloses a cleaning device for a textile air conditioner sandproof window, whose driving component adopts a sliding guide rail 4. The window has a rectangular frame structure, and the filter cloth 2 is made of polyester fiber with an air permeability controlled at 80-120L / (m²・s), possessing both good dust interception ability and wear resistance. The filter cloth 2 is located on the outside of the window. The winding assembly 6 includes a driven roller 61 and a driving roller 62, both of which are installed on the upper and lower sides of the outside of the window through deep groove ball bearing seats. The driven roller 61 is located on the upper side, and the driving roller 62 is located on the lower side. The axes are kept parallel and the spacing is adapted to the winding length of the filter cloth 2. The driven roller 61 and the driving roller 62 are coaxially connected to a winding motor 63 at both ends, and the winding speed can be precisely controlled by a PLC controller. For the remaining structure, please refer to the patent document CN120759523A, "A Smart Sandproof Window for Textile Air Conditioners".

[0032] Please continue reading. Figure 1 and Figure 2The cleaning device 3 includes a suction nozzle 31 and a sliding guide rail 4. The sliding guide rail 4 is existing technology and is fixedly installed at the lower end of the window near the outside. The length of the sliding guide rail 4 is the same as the width of the filter cloth 2. The suction nozzle 31 is fixed to the slider (not shown) of the sliding guide rail 4 by welding. The air inlet of the suction nozzle 31 is funnel-shaped, and the distance between the edge of the air inlet and the surface of the filter cloth 2 is set to 2-5mm. This distance ensures that the airflow can adsorb dust during negative pressure adsorption, while avoiding direct contact between the suction nozzle 31 and the filter cloth 2, which would cause fiber wear. The suction nozzle 31 is connected to the negative pressure source through a rubber hose. In this embodiment, the negative pressure source is a vacuum cleaner 310. The vacuum cleaner 310 is an industrial vacuum cleaner, and its suction port is connected to the rubber hose through a three-way connector.

[0033] In actual use, once the filter cloth 2 has trapped dust to a preset thickness, the winding motor 63 of the winding assembly 6 is activated. The winding motor 63 drives the active roller 62 to rotate, pulling the used old filter cloth 2 from the driven roller 61 and winding it up. At the same time, the driven roller 61 releases the new filter cloth 2, which unfolds vertically and fits tightly against the windward side of the window. During the synchronous winding and unfolding of the filter cloth 2, the sliding guide rail 4 is powered on and activated, causing the slider to move back and forth rapidly along the length of the sliding guide rail 4. Simultaneously, the vacuum cleaner 310 is turned on, and negative pressure is transmitted to the nozzle 31 through the rubber hose. The funnel-shaped air inlet forms an adsorption airflow, which thoroughly adsorbs and cleans the cotton dust, road dust, and other particulate matter on the surface of the filter cloth 2 closest to the outside.

[0034] Example 2: Please see Figures 3-5The difference between this embodiment and the previous embodiment is that a louver 1 is provided on the inner side of the window, and the length and width of the louver 1 are both greater than the diameter of the window, so that it can completely cover the window. It also includes a driving device 7 for driving the driven roller 61 and the driving roller 62 to move towards the window. The driving device 7 can adopt any existing structure. For example, the driving device 7 used in this embodiment includes a horizontal slide rail 71, a slider 72, and a lead screw 73. The horizontal slide rail 71 is horizontally arranged and parallel to the width direction of the window, and is located above the window. The lead screw 73 is horizontally arranged, with one end rotatably connected to the horizontal slide rail 71, and the free end passing through the horizontal slide rail 71 and coaxially fixedly connected to a servo motor 74 for driving its rotation. The slider 72 is slidably connected to the horizontal slide rail 71, and the slider 72 has a threaded hole that mates with the lead screw 73. The slider 72 and the lead screw 73 are threadedly connected. The support seat of the driven roller 61 is fixedly mounted on the slider 72 through a connecting plate 75. Furthermore, it also includes a guide rail 76, which is located below the window. The support base of the active roller 62 is connected to the vacuum cleaner 310, and both are equipped with pulleys 77, which are slidably disposed within the guide rail 76. In actual operation, the servo motor 74 drives the lead screw 73 to rotate forward or backward, thereby driving the slider 72 to move towards the window. This causes the driven roller 61, the active roller 62, the cleaning device 3, and the filter cloth 2 to move closer to or further away from the window, adjusting whether the filter cloth 2 is placed on the outside of the window according to the sand content in the outdoor air.

[0035] It should be noted that the positions of the drive device 7, the winding assembly 6, and the filter cloth 2 can be adjusted adaptively. For example, when there is a partition or barrier outside the window, the above devices can be set in other positions of the window, such as the upper side, the lower side, or the left side, so that the filter cloth 2 can cover or move away from the window.

[0036] Furthermore, a honeycomb heat exchanger 8 is provided on the side of the louver 1 closest to the room. An existing honeycomb heat exchanger 8 can be used. In this embodiment, the honeycomb heat exchanger 8 includes a shell 81 and heat exchange plates 82. The number of heat exchange plates 82 is several, and they are evenly and densely arranged inside the shell 81. The shell 81 is a shell with openings at both ends, so that gas can pass through the heat exchange plates 82. The heat exchange plates 82 have a honeycomb structure. A U-shaped guide pipe passes through the heat exchange plates 82. The guide pipe has an inlet end 83 and an outlet end 84. Water enters through the inlet end 83 and exits through the outlet end 84. Furthermore, the inlet end 83 and the outlet end 84 can be connected by a return pipe. A corresponding cold source and water pump can be installed on the return pipe to realize the circulation of the cooling medium in the return pipe. The honeycomb heat exchanger 8 has a heat exchange area and a flow channel structure, which allows indoor and outdoor gases to come into contact with each other when passing through the fluid in the honeycomb heat exchanger 8, thereby achieving gas heat exchange and preventing the outdoor air temperature from being too high when entering the room. At the same time, the louver blade structure works in conjunction with the honeycomb heat exchanger to prevent dust in the outside air from entering the room.

[0037] Example 3: Please see Figure 6 and Figure 7 The difference between this embodiment and the previous embodiment is that the driving component uses a reciprocating screw 5. The reciprocating screw 5 is located between the driven roller 61 and the driving roller 62 and is close to the driving roller 62 (80-120mm away from the driving roller 62). Both ends of the reciprocating screw 5 are fixed to the lower side of the window through ball bearing seats, and its length is greater than the width of the filter cloth 2. One end of the rotating shaft of the reciprocating screw 5 is coaxially fixedly connected to the drive motor 54 through a coupling. A slider 52 is slidably assembled in the threaded groove 51 of the reciprocating screw 5, and the suction nozzle 31 is fixed to the slider 52 by M6 hexagonal bolts. A guide rod 53 is connected to one side of the slider 52. The axis of the guide rod 53 is parallel to the axis of the reciprocating screw 5, and the end away from the slider 52 extends into the cylinder 33 and is fixedly connected to the piston of the cylinder 33 by a pin. The outer wall of the reciprocating screw 5 is in close contact with the side of the filter cloth 2 closest to the outside. The filter cloth 2 is wrapped around the outer circumference of the reciprocating screw 5, and under its guiding action, it smoothly transitions from the vertical section to the horizontal section (e.g., Figure 4 As shown), the bending radius at the transition point is controlled at 50-80mm (to avoid damage to the membrane due to excessive bending of the filter cloth 2). Both ends of the reciprocating screw 5 are equipped with inclined dust discharge plates 32, which are at an angle of 30-45° with the axis of the reciprocating screw 5. They are fixed to the window with bolts, and the other end is tightly fitted to the edge of the filter cloth 2 (a 5mm thick silicone strip is placed at the fitting point to ensure no dust leakage). A collection box (not shown) is provided below the free end, which can guide the dust discharged from the threaded groove 51 of the reciprocating screw 5 to the collection box below.

[0038] Please continue reading. Figure 6 and Figure 7The cleaning device 3 also includes a cylinder 33 and a rotary joint 34. The cylinder 33 is fixed to one side of the window via an L-shaped bracket (not shown). The piston of the cylinder 33 (not shown) is fixedly connected to the guide rod 53. A sealing ring (made of nitrile rubber) is provided between the piston and the inner wall of the cylinder 33 to ensure airtightness. A tension spring 332 is also connected to one side of the piston of the cylinder 33. The free end of the tension spring 332 is welded and fixed to the inner wall of the cylinder 33. In its natural state, the piston is located in the middle of the cylinder 33. The exhaust port 331 of the cylinder 33 is connected to the air inlet of the rotary joint 34 through an exhaust pipe 35. A one-way valve 351 is installed on the exhaust pipe 35 (the direction of conduction is from the cylinder 33 to the rotary joint 34) to prevent compressed air backflow from affecting the jet pressure. The air outlet of the rotary joint 34 is coaxially rotatably connected to one end of the reciprocating screw 5. An air storage chamber 56 (extending along the axis) is provided inside the reciprocating screw 5 and communicates with the air outlet of the rotary joint 34. Several air jets 55 are evenly distributed around the circumference of the reciprocating screw 5. Each air jet 55 has a flared structure and contains a sealing ball 36. The sealing ball 36 is magnetic and is welded to the inner wall of the air jet 55 by a spring 361. When the spring 361 is in its natural state, the sealing ball 36 seals the air jet 55. The spring 361 is non-magnetic.

[0039] Please continue reading. Figure 6 and Figure 7 A magnetic fixing plate 37 is provided on the vertical section of the filter cloth 2 near the room. It is fixed to the window side by bolts. The fixing plate 37, the push switch 38 and the air receiving plate 39 are all tilted towards the filter cloth 2 (tilt angle 20-30°) and are higher than the horizontal center line of the reciprocating screw 5 (height difference 30mm) to ensure that the airflow from the jet nozzle 55 can act on the filter cloth 2 and the air receiving plate 39. The push-button switch 38 is fixed to the fixed plate 37 by screws. The trigger end is hinged to the air receiving plate 39, which is made of lightweight plate material. A compression spring 391 is connected to one side of the air receiving plate 39. The free end of the compression spring 391 is fixed to the fixed plate 37. The compression spring 391 is non-magnetic to prevent the fixed plate 37 from attracting the compression spring 391. In the natural state, the distance between the air receiving plate 39 and the trigger end of the push-button switch 38 is 5-8mm. The push-button switch 38 is electrically connected to the alarm (model: sound and light alarm) through a wire. The alarm is installed on the panel of the workshop control room and can indicate the damage status of the filter cloth 2.

[0040] The working process of this embodiment is as follows: Start the winding motor 63, the active roller 62 rotates and pulls the old filter cloth 2 to move from the window, after being guided by the reciprocating screw 5, it transitions from the vertical section to the horizontal section and is wound up to the active roller 62. At the same time, the driven roller 61 releases the new filter cloth 2 to cover the windward side of the window; Simultaneously start the drive motor 54, drive the reciprocating screw 5 to rotate, drive the slider 52 and the suction nozzle 31 to move back and forth quickly along the width direction of the filter cloth 2 through the threaded groove 51, and turn on the vacuum cleaner 310 to absorb the dust on the surface of the filter cloth 2. When slider 52 moves, guide rod 53 drives piston of cylinder 33 to reciprocate. Compressed air is introduced into air storage chamber 56 through exhaust pipe 35, one-way valve 351 and rotary joint 34. When reciprocating screw 5 rotates to the point where jet nozzle 55 is tilted towards filter cloth 2, sealing ball 36 is attracted by fixed plate 37 and detaches from jet nozzle 55 (spring 361 is stretched). Compressed air is ejected from jet nozzle 55, forming a blow-off effect on cotton dust and impurities on filter cloth 2. This, combined with suction nozzle 31, improves cleaning efficiency. During the cleaning process, dust is adsorbed by suction nozzle 31 and guided by dust discharge plate 32, and collected in collection box, without scattering or returning to the workshop. If filter cloth 2 has damaged holes (hole diameter ≥ 1mm), airflow passes through the holes and acts on air receiving plate 39. Air receiving plate 39 overcomes the elastic force of compression spring 391 and triggers press switch 38, and alarm sounds and lights. After winding is completed, the winding motor 63 stops, and the inertia of the driven roller 61 causes the tension of the filter cloth 2 to decrease. At this time, the tension spring 332 releases its elastic potential energy, pulls the piston and guide rod 53 to reset, drives the slider 52 to move in the opposite direction and drives the reciprocating screw 5 to rotate slightly (angle 5-10°), applying compensating tension to the filter cloth 2 to ensure that the filter cloth 2 fits the window flat and avoids wrinkles and loosening.
