Description

Technical Field

[0001] This invention belongs to the technical field of thermal insulation pipe processing equipment, and relates to an automatic production device and method for thermal insulation pipes, specifically to a fully automatic production system and method for thermal insulation cotton type steam thermal insulation pipes. Background Technology

[0002] Insulated cotton steam pipes are key heat transport components consisting of steel pipes wrapped with insulating cotton. Their insulation performance directly depends on the material selection, number of wrapping layers, and bonding precision of the insulating cotton. Among them, aluminum silicate fiber blankets are the preferred insulating cotton material for steam pipes due to their high temperature resistance and low thermal conductivity.

[0003] In existing technology, the processing of this type of insulation pipe relies entirely on manual operation. The specific process is as follows: rolls of insulation cotton and the steel pipe to be processed are set up separately in an open area. Workers first pull out one end of the insulation cotton and fix it to the bottom of the steel pipe. After cutting it to the required size, several workers work together to wrap the insulation cotton around the surface of the steel pipe by hand. Finally, it is secured manually with tape. This processing method has the following intractable technical defects:

[0004] 1. Extremely high labor intensity and low efficiency: The insulation cotton wrapping of a single steel pipe requires multiple workers to work together. Especially for long steel pipes or multi-layer wrapping needs, the operation cycle is long, the labor cost is high, and the speed of manual wrapping is inconsistent, which makes it difficult to improve production efficiency and meet the needs of large-scale production.

[0005] 2. Harsh working environment and health hazards: The fibers of aluminum silicate fiber blankets are fine and easy to fall off. Even if workers wear protective clothing, the fibers can still penetrate the protective clothing and come into contact with the skin, causing allergic reactions such as itching and redness. Long-term inhalation may also harm the respiratory system. Especially in the high temperature environment of summer, the airtightness of the protective clothing further aggravates the stuffiness and discomfort, seriously affecting the workers' working experience and physical health.

[0006] 3. Poor processing precision and unstable product quality: During manual winding, the tension and overlap precision of the insulation cotton are entirely controlled by the worker's experience, which can easily lead to problems such as loose winding, wrinkles, and excessively large overlap gaps, resulting in uneven insulation performance of the insulation pipe; at the same time, when manually cutting the insulation cotton, the dimensional error is large, which further affects the consistency of the product.

[0007] Therefore, it is essential to design a fully automated production system and method for thermal insulation cotton type steam insulation pipes. Summary of the Invention

[0041] A fully automated production method for thermal insulation cotton type steam insulation pipes, characterized by the following steps:

[0042] Step 1, Device Initialization and Parameter Setting

[0043] Operators input production parameters through the control cabinet, including steel pipe length and diameter, insulation cotton cutting length, width, number of wrapping layers, tape wrapping spacing, and outer protective layer specifications.

[0044] The equipment automatically completes initial adjustments: the mobile trolley of the steel pipe feeding device moves to the steel pipe feeding station, and the rotating drive roller is adjusted to a height suitable for the diameter of the steel pipe; the guide baffle spacing of the insulation cotton conveying and cutting unit is adjusted to a width suitable for the insulation cotton, and the cutting components are calibrated to the set cutting size; the distance between the sliding baffle and the fixed baffle of the insulation cotton feeding overlap unit is adjusted to a width suitable for the insulation cotton; the distance between the pneumatic grippers of the outer protective layer and the position of the cutting components of the outer protective layer setting device are adjusted to a size suitable for the outer protective layer specifications.

[0045] Check whether there is enough insulation cotton on the insulation cotton storage rack, tape rolls on the tape roll installation mechanism, and aluminum foil rolls on the outer protective layer feeding assembly. Also check whether the air filter of the protective shell is working properly to ensure that the equipment is free of abnormalities.

[0046] Step 2, Steel pipe loading and positioning

[0047] The steel pipe to be processed is manually hoisted onto the rotating drive roller of the steel pipe feeding device, and the operator starts the steel pipe positioning program through the control cabinet.

[0048] The mobile geared motor drives the mobile vehicle body to move along the conveyor slide rail, and the absolute encoder provides real-time feedback of displacement information, enabling the steel pipe to move precisely to the insulation cotton overlapping station.

[0049] The lifting and reducing motor drives the worm gear lifting machine to adjust the height of the rotating drive roller, so that the center of the steel pipe is aligned with the overlap height of the insulation cotton feeding overlap unit, thus completing the steel pipe positioning.

[0050] Step 3: Insulation cotton conveying, cutting and overlapping

[0051] Insulation cotton conveying: The insulation cotton end on the storage rack is manually pulled to the insulation cotton traction and cutting platform. The pressing cylinder of the pressing component drives the pressing plate to descend and fix the insulation cotton end. The drive motor of the traction component starts, and the synchronous belt drives the traction pneumatic gripper to hold the insulation cotton end and pull it backward along the insulation cotton conveying area. The traction speed is matched with the set parameters.

[0052] Insulation cotton cutting: When the insulation cotton is pulled to the set length, the pressing component presses and fixes the insulation cotton again. The cylinder of the cutting component drives the cutting lifting plate to descend, the cutting motor starts, and at the same time the cutting sliding motor drives the cutting sliding frame to move along the cutting slide rail mounting beam. The insulation cotton cutting knife completes the fixed-length cutting of the insulation cotton. If fixed-width cutting is required, the swing cylinder drives the rotary support to adjust the direction of the insulation cotton cutting knife, and the cutting action is repeated to complete the width cutting.

[0053] Insulation cotton overlap: The transverse feeding gear drive motor of the feeding traction mechanism starts, driving the feeding pneumatic gripper to move to the rear end of the insulation cotton traction and cutting platform, and clamping the cut insulation cotton; the feeding traction mechanism drives the insulation cotton to move backward to above the steel pipe, and the lifting drive motor drives the longitudinal profile to descend, overlapping the rear end of the insulation cotton with the set starting position of the steel pipe, and the front end with the liner of the feeding guide mechanism; the feeding pneumatic gripper releases, completing the single-layer insulation cotton overlap;

[0054] Step 4, secure with insulating tape

[0055] The adhesive cylinder of the insulation cotton fixing device drives the adhesive cylinder to extend and stick the tape to the starting position of the insulation cotton overlap, so that the adhesive surface of the tape is tightly attached to the insulation cotton;

[0056] The rotary drive motor starts, causing the steel pipe to rotate counterclockwise at a uniform speed. At the same time, the bonding motor of the tape bonding and cutting mechanism drives the tape bonding slider to move along the tape bonding slide rail, so that the tape is evenly wrapped around the surface of the insulation cotton. The driving hydraulic cylinder of the rotary pressure plate assembly drives the rotary pressure plate to tilt forward and press it onto the insulation cotton, ensuring that the insulation cotton adheres to the rotating steel pipe.

[0057] After the steel pipe rotates once, the tape secures the insulation cotton. The tape cutting cylinder of the cutting component drives the tape cutting blade to extend and cut the tape.

[0058] Step 5, Laying and fixing the outer protective layer

[0059] Outer Sheet Conveying and Cutting: The aluminum foil end on the outer sheet feeding assembly passes sequentially around the first winding shaft, the second winding shaft, the third winding shaft, and the pressing shaft, and is placed between the material support plate and the pressing shaft. The outer sheet pneumatic gripper holds the aluminum foil end. The feeding pneumatic gripper of the feeding traction mechanism moves to the front end of the outer sheet feeding mechanism, holds the aluminum foil end, and pulls it forward. After the diffuse reflection sensor detects the movement of the aluminum foil, the outer sheet pneumatic gripper releases. When the aluminum foil is pulled to the set length, the cutter of the outer sheet cutting assembly moves along the cutting straight slide rail to complete the cutting of the aluminum foil.

[0060] Tape pre-positioning: The tape trolley moves to the starting position of the outer protective layer overlap, pulls the tape on the tape roll diagonally upward and sticks it to the insulation cotton. The insulation tube remains stationary. The brake motor of the rotation drive component starts, drives the drive gear to rotate through the drive belt, and then drives the rotation power wheel to rotate, so that the rotating ring rotates counterclockwise and rotates to the front end position of the insulation tube.

[0061] Outer protective layer overlap: The feeding traction mechanism overlaps the cut aluminum foil cloth onto the surface of the steel pipe wrapped with insulation cotton, with the front end of the aluminum foil cloth placed at the tape at the front end of the steel pipe.

[0062] Outer protective layer fixing: The rotating ring continues to rotate, evenly wrapping the tape around the surface of the aluminum foil cloth; at the same time, the tape trolley moves at a constant speed along the conveyor rail to complete the wrapping and fixing of the outer protective layer of the entire steel pipe; after the wrapping is completed, the cutting cylinder of the tape cutting component drives the blade to extend and cut the tape.

[0063] Step 6, Finished product unloading

[0064] After the outer protective layer is fixed, the mobile vehicle body of the steel pipe feeding device moves along the conveyor slide rail to the finished product unloading station;

[0065] The lifting and reduction motor drives the rotating drive roller to descend, and the operator uses hoisting equipment to lift the processed insulation pipe off the equipment and place it in the finished product storage area.

[0066] The advantages and positive effects of this invention are:

[0067] 1. The fully automated production system and method for this thermal insulation cotton type steam insulation pipe achieves automated production of thermal insulation cotton type steam insulation pipe through the coordinated operation of steel pipe feeding device, thermal insulation cotton feeding device and thermal insulation cotton fixing device. It completely replaces the traditional manual winding and fixing of thermal insulation cotton, greatly reduces the labor intensity of workers, and especially avoids the skin irritation caused by workers directly contacting thermal insulation cotton (such as aluminum silicate fiber blanket).

[0068] 2. The fully automated production system and method for this type of thermal insulation steam pipe includes a thermal insulation cotton conveying and cutting unit that achieves fixed-length and fixed-width cutting of the thermal insulation cotton through synchronous belt drive of the traction component and precise positioning of the cutting component. Guide baffles restrict the conveying path to prevent thermal insulation cotton deviation. The thermal insulation cotton feeding and overlapping unit achieves a ±1mm overlap error through bidirectional precise drive of the transverse feeding traction slide rail and the longitudinal feeding slide rail. Combined with the rotating pressure plate component, this ensures the thermal insulation cotton is tightly adhered to the steel pipe surface, preventing tangling, loosening, and wrinkling. The outer protective layer setting device detects the position of the outer protective layer through a diffuse reflection sensor. Combined with precise cutting by the cutting component and tape wrapping for fixation, this ensures the outer protective layer is laid flat and securely sealed.

[0069] 3. The present invention is scientifically and rationally designed, and has the advantages of reducing labor intensity, improving processing efficiency, benefiting the workshop environment, and being easy to implement. It is a highly innovative fully automatic production system and method for thermal insulation cotton type steam insulation pipes. Attached Figure Description

An insulation cotton traction and cutting platform perpendicular to the horizontal direction is set in front of the conveying slide rail. An insulation cotton traction and cutting mechanism is installed on the insulation cotton traction and cutting platform. An insulation cotton storage rack is set in front of the insulation cotton traction and cutting platform. Rolls of insulation cotton are placed on the insulation cotton storage rack. A rotatable bracket is used to reduce the resistance when the insulation cotton is tractioned.

A connecting shaft is connected between the two synchronous pulleys at the rear end, and a protective cover is covered on the connecting shaft. The synchronous pulley on the rear end side is driven by the drive motor, thereby realizing the transmission of each synchronous pulley. A slider is slidably installed on the conveying linear traction slide rail, and a slider connecting frame is installed on the slider. The synchronous belt is fixed to the slider connecting frame by a pressure plate. A connecting beam is installed between the two slider connecting frames on the left and right sides. The slider connecting frame and the connecting beam together form a sliding mounting frame. Traction pneumatic grippers are spaced apart on the connecting beam.

[0098] Guide baffles 31 are installed on the inner side of the two conveying linear traction slide rails on the insulation cotton traction and cutting platform, and the position between the two guide baffles forms the insulation cotton conveying area.

[0099] When in use, adjust the distance between the two guide baffles according to the width of the insulation cotton so that it can be conveyed along the insulation cotton conveying area during traction;

[0100] Before production, the end of the insulation cotton is placed manually on the insulation cotton traction and cutting platform. At this time, the pressing plate on the pressing assembly limits the insulation cotton. When feeding, the pressing plate releases the limit on the insulation cotton, and the traction pneumatic gripper clamps the end of the insulation cotton and pulls it along the insulation cotton traction and cutting platform. When it moves to the required size, the pressing plate continues to press and limit the insulation cotton. The fixed length cutting of the insulation cotton is completed by the movement of the cutter. This process is repeated to complete the cutting of multiple pieces of insulation cotton.

[0101] The cut insulation cotton is pulled to the rear end of the insulation cotton pulling and cutting platform by the traction pneumatic gripper.

[0102] The insulation cotton feeding overlap unit includes a feeding mounting frame and a feeding traction mechanism 17. The feeding mounting frame includes a front upright frame 15, a rear upright frame 21 and a top support. The front upright frame and the rear upright frame are symmetrically installed at the front and rear ends of the conveying slide rail, respectively. A top support is installed on the top of the front upright frame and the rear upright frame. A sliding mounting port is opened in the middle of the top support.

[0104] A transverse profile 51 is installed at the bottom of the longitudinal profile, and a pneumatic feeding gripper 52 is installed at the front end of the transverse profile.

[0105] The insulation cotton feeding overlap unit also includes a feeding guide mechanism 16, which includes a guide mechanism mounting frame 39, a guide frame, a liner, a connecting rod 35, a fixed baffle 37, a sliding baffle 34, a spacing adjustment motor 36, an adjusting screw, a slide block, a guide linear slide rail, a guide slider, and a slider connecting plate. The guide frame is obliquely mounted on the front upright frame via the guide mechanism mounting frame. The guide frame includes a planar frame 33 and a mounting frame 38 located on the bottom surface of the planar frame. Two moving seams are provided on the planar frame, and liner plates are provided on both sides of the moving seams. A fixed baffle is fixedly installed at one end of the moving seam, and a sliding baffle is slidably installed in the moving seam via the connecting rod. The lower end of the connecting rod is connected to the slider connecting plate, and the slider connecting plate is slidably installed on the guide linear slide rail via the guide slider. The guide linear slide rail is installed on the mounting frame. An adjusting screw driven by the spacing adjustment motor is provided in the middle of the mounting frame, and a slide block is threaded onto the adjusting screw. The slide block is connected to the bottom surface of the slider connecting plate.

[0106] Adjust the distance between the sliding baffle and the fixed baffle according to the width of the insulation cotton to ensure that the insulation cotton can overlap the set position of the steel pipe. The pneumatic gripper for feeding holds the insulation cotton placed at the rear end of the insulation cotton traction and cutting platform and pulls it backward. After reaching the set position, the insulation cotton is released. At this time, the rear end of the insulation cotton overlaps the steel pipe, and the front end overlaps the liner of the feeding guide mechanism.

[0107] The insulation cotton fixing device includes a tape roll installation mechanism and a tape pasting and cutting mechanism 18. An upper mounting frame and a lower mounting frame are installed horizontally on the rear support frame.

A device driven by a pasting motor is installed on the tape pasting rack. A movable tape-sticking gear has a tape-sticking slider slidably mounted on a tape-sticking slide rail. A slider connecting plate is connected to the tape-sticking slider. The slider connecting plate is mounted on a guide rail mounting frame. A telescopic frame is mounted at the front end of the guide rail mounting frame. Mounting side plates are mounted at both ends of the telescopic frame. Multiple sets of tape guide assemblies are mounted between the two mounting side plates. The tape guide assembly includes a roller shaft 57 and a tape roller 56. The roller shaft is mounted between the two mounting side plates, and a tape roller is mounted on the roller shaft at the position corresponding to the tape roll.

[0109] A tape pasting component is provided at the lower end of each tape guide component. The tape pasting component includes a pasting cylinder (not shown in the figure) and a pasting pressure cylinder 55. A tape pasting mounting beam is installed between the two mounting side plates. A pasting cylinder is installed on the tape pasting mounting beam at the position corresponding to each pasting pressure cylinder. The pasting cylinder drives the pasting pressure cylinder to be installed.

[0110] A cutting component is installed at the lower end of each tape application assembly. The cutting component includes a cutting mounting frame, a tape cutting cylinder 53, and a tape cutting blade 54. A cutting mounting frame is installed on the tape application mounting beam at the position corresponding to each application cylinder. A tape cutting cylinder is installed on the cutting mounting frame and tilted upwards. A tape cutting blade is driven and installed on the tape cutting cylinder.

[0111] In this embodiment, five tape roll installation mechanisms are evenly spaced, with a tape roll installed on each mechanism. The tape end of the tape roll successively passes over the tape roller on the tape guide assembly and then overlaps the adhesive pressure cylinder of the tape adhesive assembly below. At this time, the adhesive surface of the tape faces the steel pipe. During operation, the adhesive cylinder drives the adhesive pressure cylinder to extend and adhere the tape to the steel pipe. As the steel pipe rotates counterclockwise, the tape fixes the insulation cotton overlapping the steel pipe. After the steel pipe rotates one revolution, the insulation cotton is wrapped and fixed on the steel pipe.

[0112] This invention also includes a rotating pressure plate assembly, comprising a driving hydraulic cylinder 43, a rotating connecting plate 45, and a rotating pressure plate 41. Rotating connecting plates are hinged to the outer sides of both mounting side plates. The cylinder rod of the driving hydraulic cylinder is connected to the middle of the rotating connecting plate, and the driving hydraulic cylinder is mounted on the mounting side plate. A forward-tilting rotating pressure plate is connected to the front end of the rotating connecting plate. During operation, the cylinder rod of the driving hydraulic cylinder extends, driving the rotating pressure plate to tilt forward and rotate, pressing it against the insulation cotton. This ensures the insulation cotton adheres to the steel pipe during rotation, guaranteeing the stability of the bond with the tape.

[0113] After the insulation pipe is processed, an outer protective layer can be installed on its exterior. The outer protective layer is aluminum foil cloth, which is achieved through the outer protective layer setting device 5. An outer protective layer setting device is installed side by side on the right end of the insulation cotton feeding overlap unit, spanning the conveyor slide rail. The outer protective layer setting device is used to set the outer protective layer on the steel pipe wrapped with insulation cotton.

[0114] The outer protective layer setting device includes an outer protective layer feeding overlap unit and an outer protective layer fixing unit 19. The outer protective layer feeding overlap unit includes a feeding mounting frame, a feeding traction mechanism, and an outer protective layer feeding mechanism 20. The structure of the feeding mounting frame and the feeding traction mechanism is the same as that of the insulation cotton feeding overlap unit. A feeding pneumatic gripper is installed at the rear end of the transverse profile of the feeding traction mechanism. The feeding traction mechanism is slidably installed on the top of the feeding mounting frame. The outer protective layer feeding mechanism is installed on the rear upright of the feeding mounting frame. The feeding traction mechanism is used to pull out the outer protective layer placed on the outer protective layer feeding mechanism and overlap it on the steel pipe.

[0115] The outer sheath feeding mechanism includes an outer sheath mounting frame, an outer sheath feeding assembly, a material support plate 76, a diffuse reflection sensor 77, an outer sheath pneumatic gripper 75, and an outer sheath cutting assembly 78. The outer sheath mounting frame is mounted on the rear upright, the outer sheath feeding assembly is mounted on the outer sheath mounting frame, the outer sheath cutting assembly is mounted on the upper end of the outer sheath feeding assembly, the outer sheath pneumatic grippers are mounted on both sides of the front end of the outer sheath mounting frame, a material support plate is spaced between the two pneumatic grippers, a diffuse reflection sensor is mounted on the material support plate, and a hole is provided on the upper surface of the material support plate. The emitting end of the diffuse reflection sensor corresponds to the hole. The diffuse reflection sensor is signal-connected to the outer sheath pneumatic gripper to detect the movement state of the aluminum foil cloth. When the aluminum foil cloth is detected to be pulled, the outer sheath pneumatic gripper is controlled to release.

[0116] The outer protective layer feeding assembly includes a material roller mounting shaft, a first winding shaft, a second winding shaft, a third winding shaft, and a pressing shaft. The material roller mounting shaft is installed at the rear end of the outer protective layer mounting frame. The first winding shaft and the second winding shaft are installed at the front end of the material roller mounting shaft. The third winding shaft is installed between the first winding shaft and the second winding shaft. The upper end face of the third winding shaft is lower than the lower end face of the first winding shaft and the second winding shaft. The upper end face of the material roller mounting shaft is lower than the lower end face of the first winding shaft. The pressing shaft 74 is arranged diagonally above the second winding shaft. The material support plate is placed directly below the pressing shaft.

[0117] The outer sheath cutting assembly includes a cutting linear slide rail, a cutting blade mounting plate, and a cutting blade. The cutting linear slide rail is installed above the front end of the outer sheath mounting frame. The cutting mounting plate is installed on the side of the slider of the cutting linear slide rail, and a cutting blade for cutting the outer sheath is installed on the cutting mounting plate.

[0118] The aluminum foil roll 79 is mounted on the material roller mounting shaft. The end of the aluminum foil roll passes through the first winding shaft, the second winding shaft and the third winding shaft in sequence, and is placed between the material support plate and the pressing shaft. The end of the aluminum foil roll is clamped on the pneumatic gripper of the outer protective layer.

[0119] The pneumatic gripper clamps the aluminum foil cloth and feeds it. At this time, the diffuse reflection sensor detects that the position of the aluminum foil cloth has changed, the outer protective layer pneumatic gripper releases, and the feeding pneumatic gripper moves forward with the aluminum foil cloth. After moving into position, the diffuse reflection sensor detects that the position of the aluminum foil cloth has not changed, the outer protective layer pneumatic gripper clamps the aluminum foil cloth again, and the cutter cuts the aluminum foil cloth so that the aluminum foil cloth overlaps on the insulation cotton.

[0120] The outer protective layer fixing unit includes a tape trolley 58, a top tape winding bracket 60, a side tape winding bracket 64, a rotating ring 63, a tape winding wheel 61, a rotating power wheel, a power wheel baffle 65, a rotating drive assembly, and a tape cutting assembly 62. The tape trolley is slidably mounted on the conveyor rail. The tape trolley has a U-shaped frame structure. A top tape winding bracket is located at the top of the U-shaped frame structure, and side tape winding brackets are located on both sides of the U-shaped frame structure. Rotating power wheels are evenly distributed in a ring on the top and side tape winding brackets. Power wheel baffles are installed on both sides, and the space between the two power wheel baffles forms a limiting groove. On the inner side of the portal frame structure, a ring of evenly distributed support rollers 59 are installed through a support roller mounting bracket. The rotating ring is set between the limiting groove and the support rollers. The rotating ring is rotated by driving the rotating power wheel through the rotating drive assembly. The tape roll is installed on the rotating ring, and a tape roll is installed on the tape roll. The tape roll can clamp the tape roll. The contact of the limit switch is placed on the tape roll. The limit switch is installed on the side tape winding bracket. The tape cutting assembly is installed on the side tape winding bracket.

[0121] Two rotating power wheels located in the middle of the side tape winding bracket are driven by a rotating drive assembly, which includes a brake motor 67, a rotating bearing mounting seat, a drive gear 68, and a drive toothed belt 66. The axle of the rotating power wheel extends from the back of the side tape winding bracket and is connected to one end of the rotating shaft of the rotating bearing mounting seat. The other end of the rotating shaft is connected to a drive gear. The two drive gears rotate through the cooperation of the brake motor and the drive toothed belt, thereby realizing the rotation of the rotating power wheel.

[0122] The tape cutting assembly includes a cylinder mounting plate 69, a cylinder mounting bracket 72, a cutting mounting bracket 70, a cutting cylinder 73, and a blade 71. The cylinder mounting plate is mounted on the back of the side tape winding bracket. The end of the cylinder mounting plate extends from the inside of the rotating ring. The cylinder mounting bracket is mounted on the extended part. The cutting mounting bracket driven by the cutting cylinder is mounted on the cylinder mounting bracket. The cutting mounting bracket is located on one side of the rotating ring. The blade is mounted on the cutting mounting bracket.

[0123] When using, pull out the tape and stick it to the insulation cotton. The rotating ring will rotate counterclockwise half a turn and be placed at the front end of the insulation steel pipe. After the aluminum foil is overlapped, the rotating ring continues to rotate counterclockwise to wrap the tape around the outside of the aluminum foil. As the tape is wrapped, the aluminum foil is also wrapped around the insulation pipe.

[0124] An absolute encoder is installed on the conveyor belt trolley. The operation of setting the outer protective layer on the entire insulation pipe is completed by the movement of the conveyor belt trolley on the conveyor rail.

[0125] To further protect the workshop environment and the health of workers, and to reduce the spread of aluminum silicate fiber blankets in the workshop, this invention also includes a protective outer shell. The protective outer shell is installed on the outside of the insulation cotton feeding device, the insulation cotton fixing device, and the outer protective layer setting device. An air filter is provided on the protective shell to adsorb the fibers. The air filter uses HEPA high-efficiency filter material with a filtration efficiency of ≥99.97%, effectively adsorbing aluminum silicate fibers in the air.

[0126] An innovative fully automated production method for thermal insulation cotton type steam insulation pipes includes the following steps:

[0127] Step 1, Device Initialization and Parameter Setting

[0128] Operators input production parameters through the control cabinet, including steel pipe length and diameter, insulation cotton cutting length, width, number of wrapping layers, tape wrapping spacing, and outer protective layer specifications.

[0129] The equipment automatically completes initial adjustments: the mobile trolley of the steel pipe feeding device moves to the steel pipe feeding station, and the rotating drive roller is adjusted to a height suitable for the diameter of the steel pipe; the guide baffle spacing of the insulation cotton conveying and cutting unit is adjusted to a width suitable for the insulation cotton, and the cutting components are calibrated to the set cutting size; the distance between the sliding baffle and the fixed baffle of the insulation cotton feeding overlap unit is adjusted to a width suitable for the insulation cotton; the distance between the pneumatic grippers of the outer protective layer and the position of the cutting components of the outer protective layer setting device are adjusted to a size suitable for the outer protective layer specifications.

[0130] Check whether there is enough insulation cotton on the insulation cotton storage rack, tape rolls on the tape roll installation mechanism, and aluminum foil rolls on the outer protective layer feeding assembly. Also check whether the air filter of the protective shell is working properly to ensure that the equipment is free of abnormalities.

[0131] Step 2, Steel pipe loading and positioning

[0132] The steel pipe to be processed is manually hoisted onto the rotating drive roller of the steel pipe feeding device, and the operator starts the steel pipe positioning program through the control cabinet.

[0133] The mobile geared motor drives the mobile vehicle body to move along the conveyor slide rail, and the absolute encoder provides real-time feedback of displacement information, enabling the steel pipe to move precisely to the insulation cotton overlapping station.

[0134] The lifting and reducing motor drives the worm gear lifting machine to adjust the height of the rotating drive roller, so that the center of the steel pipe is aligned with the overlap height of the insulation cotton feeding overlap unit, thus completing the steel pipe positioning.

[0135] Step 3: Insulation cotton conveying, cutting and overlapping

[0136] Insulation cotton conveying: The insulation cotton end on the storage rack is manually pulled to the insulation cotton traction and cutting platform. The pressing cylinder of the pressing component drives the pressing plate to descend and fix the insulation cotton end. The drive motor of the traction component starts, and the synchronous belt drives the traction pneumatic gripper to hold the insulation cotton end and pull it backward along the insulation cotton conveying area. The traction speed is matched with the set parameters.

[0137] Insulation cotton cutting: When the insulation cotton is pulled to the set length, the pressing component presses and fixes the insulation cotton again. The cylinder of the cutting component drives the cutting lifting plate to descend, the cutting motor starts, and at the same time the cutting sliding motor drives the cutting sliding frame to move along the cutting slide rail mounting beam. The insulation cotton cutting knife completes the fixed-length cutting of the insulation cotton. If fixed-width cutting is required, the swing cylinder drives the rotary support to adjust the direction of the insulation cotton cutting knife, and the cutting action is repeated to complete the width cutting.

[0138] Insulation cotton overlap: The transverse feeding gear drive motor of the feeding traction mechanism starts, driving the feeding pneumatic gripper to move to the rear end of the insulation cotton traction and cutting platform, and clamping the cut insulation cotton; the feeding traction mechanism drives the insulation cotton to move backward to above the steel pipe, and the lifting drive motor drives the longitudinal profile to descend, overlapping the rear end of the insulation cotton with the set starting position of the steel pipe, and the front end with the liner of the feeding guide mechanism; the feeding pneumatic gripper releases, completing the single-layer insulation cotton overlap;

[0139] Step 4, secure with insulating tape

[0140] The adhesive cylinder of the insulation cotton fixing device drives the adhesive cylinder to extend and stick the tape to the starting position of the insulation cotton overlap, so that the adhesive surface of the tape is tightly attached to the insulation cotton;

[0141] The rotary drive motor starts, causing the steel pipe to rotate counterclockwise at a uniform speed. At the same time, the bonding motor of the tape bonding and cutting mechanism drives the tape bonding slider to move along the tape bonding slide rail, so that the tape is evenly wrapped around the surface of the insulation cotton. The driving hydraulic cylinder of the rotary pressure plate assembly drives the rotary pressure plate to tilt forward and press it onto the insulation cotton, ensuring that the insulation cotton adheres to the rotating steel pipe.

[0142] After the steel pipe rotates once, the tape secures the insulation cotton. The tape cutting cylinder of the cutting component drives the tape cutting blade to extend and cut the tape.

[0143] Step 5, Laying and fixing the outer protective layer

[0144] Outer Sheet Conveying and Cutting: The aluminum foil end on the outer sheet feeding assembly passes sequentially around the first winding shaft, the second winding shaft, the third winding shaft, and the pressing shaft, and is placed between the material support plate and the pressing shaft. The outer sheet pneumatic gripper holds the aluminum foil end. The feeding pneumatic gripper of the feeding traction mechanism moves to the front end of the outer sheet feeding mechanism, holds the aluminum foil end, and pulls it forward. After the diffuse reflection sensor detects the movement of the aluminum foil, the outer sheet pneumatic gripper releases. When the aluminum foil is pulled to the set length, the cutter of the outer sheet cutting assembly moves along the cutting straight slide rail to complete the cutting of the aluminum foil.

[0145] Tape pre-positioning: The tape trolley moves to the starting position of the outer protective layer overlap, pulls the tape on the tape roll diagonally upward and sticks it to the insulation cotton. The insulation tube remains stationary. The brake motor of the rotation drive component starts, drives the drive gear to rotate through the drive belt, and then drives the rotation power wheel to rotate, so that the rotating ring rotates counterclockwise and rotates to the front end position of the insulation tube.

[0146] Outer protective layer overlap: The feeding traction mechanism overlaps the cut aluminum foil cloth onto the surface of the steel pipe wrapped with insulation cotton, with the front end of the aluminum foil cloth placed at the tape at the front end of the steel pipe.

The steel pipe feeding device (1) moves the steel pipe (2) precisely to the insulation cotton overlapping position. The steel pipe feeding device (1) adjusts the lifting height of the steel pipe (2) so that the center of the steel pipe (2) is aligned with the overlapping height of the insulation cotton feeding overlapping unit, thus completing the positioning of the steel pipe (2). Step 3, Insulation cotton conveying, cutting and overlapping: Insulation cotton conveying: The insulation cotton end on the insulation cotton storage rack (14) is manually pulled to the insulation cotton traction and cutting platform (32). The pressing cylinder of the pressing assembly (23) drives the pressing plate to descend and fix the insulation cotton end. The drive motor of the traction assembly (30) is started, and the synchronous belt drives the traction pneumatic gripper to hold the insulation cotton end and pull it backward along the insulation cotton conveying area. The traction speed matches the set parameters. Insulation cotton cutting: When the insulation cotton is pulled to the set length, the pressing assembly (23) presses and fixes the insulation cotton again. The cylinder of the cutting assembly drives the cutting lifting plate to descend, the cutting motor starts, and at the same time the cutting sliding motor (26) drives the cutting sliding frame to move along the cutting slide rail mounting beam. The insulation cotton cutting knife (29) completes the fixed-length cutting of the insulation cotton. If fixed-width cutting is required, the swing cylinder drives the rotary support (28) to adjust the direction of the insulation cotton cutting knife (29) and repeats the cutting action to complete the width cutting.
