Description

Technical Field

[0001] This utility model relates to the field of vacuum impregnation insulating tube technology, specifically to an automatic wrapping machine for insulating tie rods. Background Technology

[0002] High-voltage switchgear is one of the most technically demanding and difficult-to-manufacture pieces of equipment in high-voltage power transmission projects. Insulating tie rods, also known as insulating tubes, are core insulating components in high-voltage switchgear. Conventional products use fiberglass cloth or aramid fiber cloth as fiber reinforcement materials, combined with an outer polyester fabric layer system. Currently, the wrapping of insulating tie rods mainly relies on manual labor using single-function wrapping machines for multiple wrapping processes, resulting in low consistency in wrapping quality and low production efficiency.

[0003] Our patent CN210415579U discloses an automatic fabric wrapping device for vacuum impregnated insulating tubes, including a controller and a fabric feeding device, a fabric guiding device, and a fabric winding device arranged in sequence. The fabric winding device includes a fabric winding frame, on which an edge-aligning mechanism, an edge-cutting mechanism, and a winding mechanism are arranged sequentially along the fiberglass fabric feeding direction. A fabric-cutting mechanism is set on one side of the winding mechanism. This integrates fabric cutting, wrapping, and rolling, avoiding the separation of these actions in the original wrapping process, thus improving production efficiency and product quality stability. Although this device improves the efficiency of fabric wrapping, it can only wrap one type of fabric at a time. Since the insulating pull rod needs to be wrapped with both fiberglass fabric and polyester process fabric layers, different fabrics need to be replaced to complete the wrapping, which still consumes a certain amount of manpower to match and change fabrics, affecting work efficiency. Furthermore, the edge-cutting mechanism of this device cannot adjust the edge-cutting distance, and different fabrics require different widths, resulting in limited use. Therefore, this automatic fabric wrapping device still needs further improvement. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an automatic cloth wrapping machine for insulating tie rods. It can wrap different fabrics, reduce manual labor, and freely adjust the cutting edge distance, thereby greatly improving ease of use and production efficiency.

[0005] This utility model is achieved through the following technical solution: an automatic fabric winding machine for insulating pull rods, comprising a fabric feeding device, a fabric guiding device, a trimming device, and a fabric winding device arranged sequentially; the fabric feeding device includes a placement box and a first fabric feeding roller rotatably installed in the placement box, on which a first fabric is wound, and the first fabric feeding roller rotates under the drive of a first power mechanism to feed the fabric; the fabric guiding device includes a fabric guiding frame, a second fabric feeding roller, and a roller pressing mechanism, the second fabric feeding roller being rotatably installed on the fabric guiding frame, on which a second fabric is wound, and the second fabric feeding roller rotates under the drive of a second power mechanism to feed the fabric; the fabric guiding frame is also provided with a first roller shaft group for conveying the first fabric and a second roller shaft group for conveying the second fabric; the roller pressing mechanism... The device includes a rotating arm hinged to a fabric guide frame, with the other end of the rotating arm connected to a pressure shaft. The pressure shaft is located above the winding fabric device. The rotating arm is connected to the fabric guide frame via a pneumatic rod. The trimming device includes an equipment frame, a first output roller shaft, a first guiding mechanism, a first trimming mechanism, a second output roller shaft, a second guiding mechanism, and a second trimming mechanism. The first output roller shaft is rotatably mounted on the equipment frame and is used to transport the first fabric. The first guiding mechanism and the first trimming mechanism are sequentially mounted on the equipment frame and are used to correct the deviation of the first fabric and trim its edges, respectively. The second output roller shaft is rotatably mounted on the equipment frame and is used to transport the second fabric. The second guiding mechanism and the second trimming mechanism are sequentially mounted on the equipment frame and are used to correct the deviation of the second fabric and trim its edges, respectively. The winding and rolling device includes a roll frame, a winding mechanism is provided on the roll frame along the feeding direction of the first fabric and the second fabric, and a fabric cutting mechanism is provided on one side of the winding mechanism.

[0006] As an optimization, the first power mechanism and the second power mechanism have the same structure, both including a fabric feeding reduction motor, a driving pulley, a driven pulley and a conveyor belt. The driving pulley is connected to the output shaft of the fabric feeding reduction motor, and the driven pulley is connected to the corresponding first or second fabric feeding roller. The driving pulley and the driven pulley are connected by a conveyor belt.

[0007] As an optimization, the first roller group includes a first guide roller, a transfer roller, and a first combing roller arranged sequentially in the transverse direction.

[0008] As an optimization, the second feeding roller and the second roller shaft group are both located above the first roller shaft group, and the second roller shaft group includes a second guide roller shaft and a second combing roller shaft arranged vertically.

[0009] As an optimization, the piston rod and the rotating arm of the pneumatic rod are hinged, and the rod seat and the guide frame of the pneumatic rod are hinged.

[0010] As an optimization, the first and second guiding mechanisms have the same structure, both being C-shaped intermediate guiding mechanisms with opposite side photocells.

[0011] As an optimization, the first and second trimming mechanisms have the same structure, both including a guide rail, a track trolley, and a trimmer. The guide rail is parallel to the first or second output roller shaft. The track trolley is mounted on the guide rail and moves along the guide rail axis. The trimmer is fixed on the track trolley, and a disc blade is mounted on the output shaft of the trimmer.

[0012] As an optimization, the track trolley is electrically driven.

[0013] As an optimization, the track trolley is equipped with an infrared ranging sensor, with the infrared ranging sensor of the first trimming mechanism facing the first fabric and the infrared ranging sensor of the second trimming mechanism facing the second fabric.

[0014] As an optimization, the take-up mechanism includes a drive roller and a driven roller, both of which are rotatably connected to the fabric roll frame. The drive roller and the driven roller rotate synchronously in the same direction through a transmission assembly. An encoder is fixedly installed on the fabric roll frame, and the output shafts of the drive roller and the encoder are connected by gear meshing.

[0015] The beneficial effects of this utility model are as follows: 1. Two types of fabric can be fed through the first and second feeding rollers. The fabric on the first feeding roller is guided and conveyed by the first roller shaft group, and the fabric on the second feeding roller is guided and conveyed by the second roller shaft group. During the conveying process, the two fabrics are respectively guided and corrected by the first and second guiding mechanisms to prevent misalignment; and are then trimmed by the first and second cutting mechanisms respectively. This fabric wrapping machine can wrap different fabrics around insulating rods. Compared with existing technologies, it eliminates the need for manual fabric replacement, reducing labor and improving work efficiency.

[0016] 2. The first and second edge-cutting mechanisms cut the edges of the first and second fabrics respectively, facilitating the cutting of different edge widths. During the cutting operation, depending on the required width of different fabrics, the edge cutter is moved axially along the guide rail by a track trolley, and the cutting distance is measured by an infrared sensor. This allows for the cutting of different edge widths on the corresponding fabrics, making it more convenient, flexible, and intelligent to use. Attached Figure Description

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0019] like Figure 1 As shown, an automatic fabric wrapping machine for insulating tie rods includes a fabric feeding device, a fabric guiding device, a trimming device, and a fabric winding device arranged in sequence. This embodiment of the automatic fabric wrapping machine also includes a controller, which is a programmable logic controller (PLC). The PLC's power input is connected to AC220V. The PLC uses an existing PLC, specifically an Omron CP1H series small PLC.

[0020] Specifically, the fabric feeding device, fabric guiding device, trimming device, and fabric winding device are arranged sequentially from left to right. The fabric feeding device includes a placement box 1 and a first fabric feeding roller 2 rotatably installed inside the placement box 1. The first fabric feeding roller 2 has the first fabric wound on it, and the first fabric feeding roller 2 rotates under the drive of a first power mechanism to feed the fabric.

[0021] The fabric guiding device includes a fabric guide frame 3, a second fabric feeding roller 4, and a roller pressing mechanism 7. The second fabric feeding roller 4 is rotatably mounted on the fabric guide frame 3, and a second fabric is wound on the second fabric feeding roller 4. The second fabric feeding roller 4 rotates under the drive of the second power mechanism to feed the fabric.

[0022] In this embodiment, the first and second power mechanisms have the same structure, both including a fabric feeding reduction motor, a driving pulley, a driven pulley, and a conveyor belt. The driving pulley is connected to the output shaft of the fabric feeding reduction motor, and the driven pulley is connected to the corresponding first fabric feeding roller 2 or second fabric feeding roller 4. The driving pulley and the driven pulley are connected by a conveyor belt. That is, the driven pulley of the first power mechanism is fixed at the end of the first fabric feeding roller 2, and the fabric feeding reduction motor of the first power mechanism drives the driven pulley to rotate through the driving pulley, thereby driving the first fabric feeding roller 2 to rotate and feed fabric. The driven pulley of the second power mechanism is fixed at the end of the second fabric feeding roller 4, and the fabric feeding reduction motor of the second power mechanism drives the driven pulley to rotate through the driving pulley, thereby driving the second fabric feeding roller 4 to rotate and feed fabric. The fabric feeding reduction motors of both the first and second power mechanisms are connected to the output circuit of the controller. Since the first and second power mechanisms are common existing drive methods, their specific structures and positions are not shown in the figure.

[0023] Specifically, the guide frame 3 is also provided with a first roller group 5 for transmitting the first fabric and a second roller group 6 for transmitting the second fabric.

[0024] In this embodiment, the first roller group 5 includes a first guide roller 51, a transfer roller 52, and a first combing roller 53 arranged sequentially in the transverse direction. The second feed roller 4 and the second roller group 6 are both located above the first roller group 5. The second roller group 6 includes a second guide roller 61 and a second combing roller 62 arranged vertically. All rollers in the first roller group 5 and the second roller group 6 are parallel to each other.

[0025] The first fabric, introduced from the first feed roller 2 by the first guide roller shaft 51, is supported and buffered by the intermediate transfer roller shaft 52, and finally tensioned by the first combing roller shaft 53 before being transferred to the trimming device for processing. The second feed roller 4 and the second roller shaft group 6 are positioned above the first roller shaft group 5, allowing the second fabric to be transferred above the first fabric without interfering with each other, ensuring operational stability. The second fabric is introduced through the second guide roller shaft 61 and tensioned by the second combing roller shaft 62 before being transferred to the trimming device for processing.

[0026] Specifically, the roller pressing mechanism 7 includes a rotating arm 71 hinged to the fabric guide frame 3. The other end of the rotating arm 71 is connected to a pressure shaft 72, which is located above the winding fabric device and is parallel to each roller of the first roller group 5. The rotating arm 71 is connected to the fabric guide frame 3 via a pneumatic rod 73. The piston rod of the pneumatic rod 73 is hinged to the rotating arm 71, and the rod seat of the pneumatic rod 73 is hinged to the fabric guide frame 3.

[0027] In this embodiment, the rotating arm 71 is hinged to the outside of the fabric guide frame 3, thereby preventing the rotating arm 71 from colliding with the fabric guide frame 3 or the internal structure of the trimming device when it rotates. Since the piston rod of the pneumatic rod 73 has a tendency to retract when it is forced to stretch, this characteristic can be used to make the pressure shaft 72 press the fabric tightly during the fabric winding process of the insulating pull rod 18, so that the fabric can be tightly wound on the insulating pull rod 18.

[0028] Specifically, the trimming device includes a frame 8, a first output roller 13, a first guiding mechanism 11, a first trimming mechanism 9, a second output roller 14, a second guiding mechanism 12, and a second trimming mechanism 10. The first output roller 13 is rotatably mounted on the frame 8 and is used to transport the first fabric. The first guiding mechanism 11 and the first trimming mechanism 9 are sequentially mounted on the frame 8 and are used for correcting the deviation of the first fabric and trimming its edges, respectively. The second output roller 14 is rotatably mounted on the frame 8 and is used to transport the second fabric. The second guiding mechanism 12 and the second trimming mechanism 10 are sequentially mounted on the frame 8 and are used for correcting the deviation of the second fabric and trimming its edges, respectively.

[0029] In this embodiment, the second output roller 14 is located above the first output roller 13. The second output roller 14 and the first output roller 13 are parallel to each other, and the second output roller 14 is parallel to the second combing roller 62, while the first output roller 13 is parallel to the first combing roller 53. Since the second fabric is transported above the first fabric, it is convenient for the second output roller 14 to lead out the second fabric, and for the first output roller 13 to lead out the first fabric.

[0030] The second guiding mechanism 12 is positioned vertically opposite the first guiding mechanism 11, with the second guiding mechanism 12 located between the second output roller 14 and the second combing roller 62, and the first guiding mechanism 11 located between the first output roller 13 and the first combing roller 53. The second guiding mechanism 12 corrects the edge alignment of the second fabric transmitted from the guiding device, preventing it from deviating. The first guiding mechanism 11 corrects the edge alignment of the first fabric transmitted from the guiding device, preventing it from deviating.

[0031] In this embodiment, the first guiding mechanism 11 and the second guiding mechanism 12 have the same structure, both being C-type intermediate guiding mechanisms with opposite edge photoelectric sensors. The specific models of the first guiding mechanism 11 and the second guiding mechanism 12 in this embodiment are intelligent winding and unwinding correction devices from Shanghai Senming Industrial Co., Ltd., which can be directly purchased and used.

[0032] The second edge-cutting mechanism 10 is vertically opposite to the first edge-cutting mechanism 9, and the vertical projection of the second edge-cutting mechanism 10 is located between the second output roller 14 and the second combing roller 62, while the vertical projection of the first edge-cutting mechanism 9 is located between the first output roller 13 and the first combing roller 53.

[0033] In this embodiment, the first trimming mechanism 9 and the second trimming mechanism 10 have the same structure, both including a guide rail 91, a track trolley 92, and a trimmer 93. The guide rail 91 is parallel to the first output roller shaft 13 or the second output roller shaft 14, and the guide rail 91 is an H-shaped guide rail 91 that extends front and rear and is fixedly connected to the equipment frame 8. The track trolley 92 is mounted on the guide rail 91 and moves axially along the guide rail 91. The track trolley 92 is electrically driven. Specifically, the two rollers of the track trolley 92 are respectively engaged in the grooves on both sides of the H-shaped guide rail 91, allowing the track trolley 92 to move along the guide rail 91. A drive motor is mounted on the track trolley 92, and the output shaft of the drive motor is connected to one of the rollers of the track trolley 92, thereby driving the movement of the track trolley 92. The drive motor is electrically connected to the output end of the controller.

[0034] The edge trimmer 93 is fixed on the track trolley 92. A disc blade is mounted on the output shaft of the edge trimmer 93, and the edge trimmer 93 is electrically connected to the output terminal of the controller. The specific model of the edge trimmer 93 is the Lemuel ELCUT BTA80, which can be purchased and used directly. The cutter disc of this model of edge trimmer 93 can be displaced a certain distance radially (i.e., in the vertical direction), so that when the edge trimmer 93 moves axially, the disc blade can avoid the fabric. When it reaches the designated position, the cutter disc of the edge trimmer 93 moves radially to make the disc blade contact the fabric for cutting.

[0035] The track trolley 92 is equipped with an infrared ranging sensor. The infrared ranging sensor of the first cutting mechanism 9 faces the first fabric, and the infrared ranging sensor of the second cutting mechanism 10 faces the second fabric. By driving the cutting device 93 to move axially along the guide rail 91 via the track trolley 92, and cooperating with the infrared sensor to measure the cutting distance of the fabric, different edge widths can be cut for the corresponding fabrics, making it more convenient, flexible and intelligent to use.

[0036] Specifically, the guide rail 91 of the first trimming mechanism 9 is located below the first fabric, making efficient use of the space below the first fabric. The track carriage 92 of the first trimming mechanism 9 is mounted on the upper part of the guide rail 91, and the trimmer 93 is fixed to the top of the track carriage 92, allowing the trimmer 93 to cut from below the first fabric. The guide rail 91 of the second trimming mechanism 10 is located above the second fabric, making efficient use of the space above the second fabric. The track carriage 92 of the second trimming mechanism 10 is mounted on the lower part of the guide rail 91, and the trimmer 93 is fixed to the lower part of the track carriage 92, allowing the trimmer 93 to cut from above the second fabric.

[0037] Specifically, the winding and rolling device includes a roll frame 15, a winding mechanism is provided on the roll frame 15 along the feeding direction of the first fabric and the second fabric, and a fabric cutting mechanism 19 is provided on one side of the winding mechanism.

[0038] In this embodiment, the take-up mechanism includes a drive roller 16 and a driven roller 17, both of which are rotatably connected to the fabric roll frame 15. The drive roller 16 and driven roller 17 rotate synchronously in the same direction via a transmission assembly. An encoder (obscured in the figure and therefore not shown) is fixedly mounted on the fabric roll frame 15. The output shafts of the drive roller 16 and the encoder are connected via gear meshing. The encoder is connected to the input circuit of a programmable logic controller (PLC). In this embodiment, the transmission assembly includes a fabric roll motor (obscured in the figure and therefore not shown) and a chain. The fabric roll motor is connected to the output circuit of the PLC, and its output shaft is connected to the drive roller 16. The drive roller 16 and driven roller 17 are driven by the chain. When the fabric roll motor rotates, it drives the drive roller 16 and driven roller 17 to rotate synchronously in the same direction.

[0039] The fabric cutting mechanism 19 described in this embodiment adopts an existing manual fabric cutting machine.

[0040] It should be noted that the specific circuit connections of the fabric unloading reduction motor, intelligent winding and unwinding correction device, edge trimmer 93, drive motor, winding motor, encoder and programmable logic controller are all existing technologies, and will not be described in detail here.

[0041] In this embodiment, in order to facilitate transfer, wheels and stop blocks are installed at the bottom of the placement box 1, the bottom of the guide frame 3, the bottom of the equipment frame 8 and the bottom of the roll frame 15. The stop blocks adopt the existing structure and their function is to limit the movement of the wheels and prevent displacement in the non-transfer state.

[0042] In use, a first fabric, such as fiberglass cloth, is mounted on the first feeding roller 2; a second fabric, such as polyester fabric, is mounted on the second feeding roller 4. The first fabric is sequentially passed through the first roller group 5, the first guiding mechanism 11, and the first output roller 13 before being led out; the second fabric is sequentially passed through the second roller group 6, the second guiding mechanism 12, and the second output roller 14 before being led out. Based on the required width of the fabric, the edge trimmer 93 of the first edge trimming mechanism 9 is moved axially. The movement distance of the edge trimmer 93 is sensed by a corresponding infrared sensor, and the movement stops when the edge trimming position is reached.

[0043] The encoder's rotation count is pre-set according to the diameter of the insulating pull rod 18, reflecting the winding length of the fabric on the insulating pull rod 18. The insulating pull rod 18 to be wound is placed between the drive roller 16 and the driven roller 17. When the first piece of fabric needs to be wound, the operator manually presses the first piece of fabric onto the insulating pull rod 18, simultaneously pressing the pressure shaft 72 onto the insulating pull rod 18. At the same time, the feeding reduction motor, the edge trimmer 93, and the winding motor are activated. Under the combined action of the drive roller 16 and the driven roller 17, the insulating pull rod 18 is forced to rotate, causing the first piece of fabric to wind around the insulating tube round by round. When the encoder reaches the set number of rotations, it transmits a signal to the programmable logic controller (PLC). The PLC then issues a command to stop the feeding reduction motor, the edge trimmer, and the winding motor. The operator then manually cuts the first piece of fabric using a manual fabric cutter. Similarly, when the second piece of fabric needs to be wound, it is wound in the same manner.

[0044] Wrap the different fabrics using the above method until the fabric of the insulating tie rod 18 is wrapped as required.

[0045] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
