Description

Technical Field

[0001] This invention belongs to the technical field of packing weaving equipment, specifically relating to an inverted packing weaving equipment. Background Technology

[0002] A packing braiding machine is a specialized piece of machinery used for braiding sealing packing (packing). Packing, as a sealing material, is widely used in shaft seals or rotary seals of equipment such as centrifugal pumps, compressors, and valves, performing particularly well in high-temperature, high-pressure, and corrosive media environments. The packing braiding machine uses a specific braiding process to weave linear materials (such as asbestos, polytetrafluoroethylene, graphite, etc.) into packing products with specific cross-sectional shapes (such as squares, rectangles, and circles).

[0003] Due to the nature of the braiding material, the braided packing will appear fluffy and swollen, and its shape and size will be inaccurate. For ordinary sealing applications, the packing may not need to be shaped. However, for critical sealing applications, in order to maintain standard dimensions, it is necessary to shape the packing using shaping equipment to ensure that the shape and size of the braided packing are accurate and consistent.

[0004] However, existing packing braiding machines do not include shaping devices, which need to be purchased separately from other manufacturers, resulting in high costs and large footprints. Therefore, equipment with shaping devices at the take-up outlet has emerged. For example, invention patent application number CN202010597345.5 discloses a high-speed rectangular integrated packing braiding machine with shaping, which belongs to the packing braiding machine category. The packing braiding machine has a core wire device connected to the upper end of the main drive device; the main drive device is fixed to the upper end of the frame; protective covers are installed around the frame and on the bottom; an immersion device or threading plate is installed in the braiding center of the lower part of the frame; a take-up device is installed on the lower side of the frame; a cantilever control box is fixed to the upper outer side of the frame with screws, and a PLC controller is installed in the cantilever control box; a shaping device is installed at the tail of the take-up device; and a rectangular track array for spindle movement is on the integrated disc of the main drive device. Advantages: It can weave rectangular packing and two colors; the speed is three times faster than normal; the lifespan is twice as long; the casting tray is a single integrated tray, greatly saving casting costs; and the shaping device attached to the machine's take-up outlet can precisely control the shape and size of the packing. This improves production efficiency and saves significant manpower and financial resources.

[0005] However, the shaping device of the above-mentioned packing braiding machine has the following technical problems when in use: because the packing is directly shaped by a single set of transmission pressure rollers, adjustable pressure caps and replaceable pressure rollers, the shaping process is too rough. During the compression shaping process, the loose and swollen packing is prone to backward movement and accumulation of packing material, resulting in disorder of the packing material and affecting the overall quality of the packing.

[0019] An inverted packing weaving device, such as Figure 1-11 As shown, the device includes a braiding machine, on which a shaping device 5 for shaping packing is connected. The shaping device 5 includes a mounting frame 28 mounted on the braiding machine. The mounting frame 28 is provided with multiple sets of shaping structures with progressively smaller shaping dimensions. Between each set of shaping structures, a flexible structure 32 for flexibly shaping the packing is provided. The flexible structure 32 includes a support cylinder 40 that moves along the packing conveying direction. A pair of vertical frames 48 corresponding to the upper and lower surfaces of the packing are slidably connected to the support cylinder 40. Several first rollers 50 for flexibly shaping the packing are rotatably connected to the vertical frames 48. A pair of transverse frames 51 corresponding to the front and rear surfaces of the packing are also slidably connected to the support cylinder 40. Several second rollers 52 for flexibly shaping the packing are rotatably connected to the transverse frames 51. The support cylinder 40 is provided with a top spring 49 for compressing the transverse frames 51 and the vertical frames 48.

[0020] In use, the packing is braided by a braiding machine, and the braided packing is conveyed to the shaping device 5 for shaping so that the shaped packing can be used in important sealing applications. Specifically, the packing is shaped sequentially by multiple shaping structures with progressively smaller shaping dimensions, so that the packing is shaped from large to small to the standard size. This effectively reduces the problem of reduced packing quality caused by the direct and rough shaping of a single shaping structure, and improves the quality of packing shaping in this application.

[0021] In addition, a flexible structure 32 is set between adjacent shaping structures. The packing is flexibly shaped by the flexible structure 32, allowing the deformed packing to stretch under the action of the flexible structure 32, and then proceed to the next level of shaping, so as to improve the shaping effect of the shaping structure on the packing and improve the quality of the packing. Specifically, by making the support cylinder 40 reciprocate along the movement direction of the packing, the support cylinder 40 drives the vertical frame 48 and the horizontal frame 51 to reciprocate. The vertical frame 48 flexibly shapes the upper and lower surfaces of the packing through the first roller 50, and the horizontal frame 51 flexibly shapes the front and rear surfaces of the packing through the second roller 52, so that the compressed packing material can stretch, thereby reducing the deformation of the packing material and improving the quality of the packing. In addition, the top spring 49 applies a compressive force to the horizontal frame 51 and the vertical frame 48, so that the first roller 50 and the second roller 52 are in close contact with the packing, thereby improving the effect of the first roller 50 and the second roller 52.

[0022] Furthermore, the braiding machine includes a frame 1, on which a braiding device 2 is provided; the frame 1 is also provided with a liquid-soaking device corresponding to the braiding device 2, and the frame 1 is also provided with a take-up device 4 that operates synchronously with the braiding device 2, the take-up device 4 being located between the liquid-soaking device and the shaping device 5.

[0023] Furthermore, such as Figure 4 As shown, the weaving device 2 includes a plurality of weaving wheels 26 rotatably connected to the frame 1 and evenly distributed along the circumference, with adjacent weaving wheels 26 meshing with each other; each of the plurality of weaving wheels 26 is coaxially fixed with a grooved wheel 27, a moving rod is provided in the groove of the grooved wheel 27, and a spindle (not shown in the figure) is connected to the moving rod; the weaving chamber is provided with a sliding groove that cooperates with the moving rod; a drive motor 11 is fixedly connected to the frame 1, and a connecting shaft 15 is fixedly connected to the output end of the drive motor 11; a connecting wheel 24 is connected to the connecting shaft 15, and an upper idler wheel 25 meshes with the connecting wheel 24, the upper idler wheel 25 meshing with one of the weaving wheels 26.

[0024] When the braiding device 2 is in use, the drive motor 11 is started. The drive motor 11 drives the connecting wheel 24 to rotate through the connecting shaft 15. The connecting wheel 24 drives one of the braiding wheels 26 to rotate through the upper idler wheel 25. Since the adjacent braiding wheels 26 mesh with each other, the remaining braiding wheels 26 rotate synchronously. The braiding wheel 26 drives the grooved wheel 27 to rotate. The grooved wheel 27 drives the moving rod to move in the groove between the adjacent grooved wheels 27. The moving rod drives the spindle to move along the slide groove, thereby braiding the packing material on the spindle into packing.

[0025] Furthermore, such as Figure 2 and Figure 3As shown, the take-up device 4 includes a drive wheel 17 connected to the connecting shaft 15, with a driven wheel 18 meshing on the drive wheel 17; a first bevel gear set 19 is connected to the driven wheel 18, a reducer 16 is connected to the output end of the first bevel gear set 19, and a second bevel gear set 20 is connected to the output end of the reducer 16; a worm gear 21 is connected to the output end of the second bevel gear set 20, with a worm wheel meshing on the worm gear 21; an input wheel is connected to the worm wheel, an output wheel is meshed on the input wheel, and a first grooved roller 12 is coaxially fixed to the output wheel; a lower idler wheel 23 is also meshed on the input wheel, a drive wheel 22 is meshed on the lower idler wheel 23, and a second grooved roller 13 is coaxially fixed to the drive wheel 22; a pressure roller frame is fixed to the frame 1, and a take-up pressure roller 14 that cooperates with the second grooved roller 13 is rotatably connected to the pressure roller frame.

[0026] When the take-up device 4 is in use, the connecting shaft 15 rotates, synchronously driving the drive wheel 17 to rotate. The drive wheel 17 drives the worm 21 to rotate through the driven wheel 18, the first bevel gear set 19, the reducer 16, and the second bevel gear set 20. The worm 21 drives the input wheel to rotate through the worm gear. The input wheel drives the first grooved roller 12 to rotate through the output wheel. The input wheel drives the second grooved roller 13 to rotate through the lower idler wheel 23 and the drive wheel 22. The second grooved roller 13 cooperates with the take-up pressure roller 14 to drive the packing through the first grooved roller 12 and the second grooved roller 13 to the shaping device 5.

[0027] Furthermore, such as Figure 2 As shown, the immersion device includes an immersion pan 3 with perforations, a plurality of lifting columns 6 fixedly connected to the immersion pan 3, and a plurality of guide cylinders 7 fixedly connected to the frame 1 to guide the plurality of lifting columns 6; a lifting motor 8 fixedly connected to the frame 1, and a nut assembly connected to the output end of the lifting motor 8; a transmission screw 9 screwed onto the nut assembly, and a lifting pan 10 fixedly connected to the transmission screw 9, and the plurality of lifting columns 6 are all fixedly connected to the lifting pan 10.

[0028] When the immersion plate 3 needs to be raised or lowered, the lifting motor 8 drives the nut pair to rotate. The nut pair and the transmission screw 9 form a screw-nut pair, which in turn drives the lifting plate 10 to rise and fall. The lifting plate 10 drives the lifting column 6 to slide along the guide cylinder 7. The lifting column 6 drives the immersion plate 3 to rise and fall. The woven packing flows through the perforations on the immersion plate 3 to the first grooved roller 12.

[0029] Furthermore, such as Figure 6 and Figure 11As shown, the shaping structure includes a transmission pressure roller 31 rotatably connected to the mounting frame 28. A fixing screw 54 is fixedly connected to the transmission pressure roller 31. An adjusting cover 53 connected by a key is sleeved on the fixing screw 54. A nut for fixing the adjusting cover 53 is screwed onto the fixing screw 54. An mounting screw 55 is rotatably connected above the transmission pressure roller 31. A replaceable pressure roller 30 is connected to the mounting screw 55 by a key. A stop block that cooperates with the replaceable pressure roller 30 is fixedly connected to the mounting screw 55. A nut for fixing the replaceable pressure roller 30 is screwed onto the mounting screw 55. A reduction motor 33 is fixedly connected to the mounting frame 28. The output end of the reduction motor 33 is connected to a drive shaft. Multiple transmission bevel gear sets 34 are connected to the drive shaft. The multiple transmission bevel gear sets 34 are coaxially fixedly connected to the multiple transmission pressure rollers 31 respectively.

[0030] When in use, the shaping structure adjusts multiple adjusting caps 53 and replaceable pressure rollers 30 according to the final dimensions of the packing. By adjusting the distance between the replaceable pressure rollers 30 and the drive pressure rollers 31, the distance between the upper and lower surfaces of the packing is changed. By adjusting the distance between the caps 53 and the drive pressure rollers 31, the distance between the front and rear surfaces of the packing is changed. In addition, the replaceable pressure rollers 30 can be replaced according to the thickness of the packing. During adjustment, the replaceable pressure rollers 30 are replaced first and fixed with nuts and stops. Next, the distance between the replaceable pressure rollers 30 and the drive pressure rollers 31 is adjusted so that multiple shaping structures sequentially shape the distance between the upper and lower surfaces of the packing. Finally, the adjusting caps 53 and the replaceable pressure rollers 30 are fitted together and the adjusting caps 53 are fixed with nuts.

[0031] During shaping, the geared motor 33 is started. The geared motor 33 drives multiple transmission bevel gear sets 34 to rotate synchronously through the drive shaft. The multiple transmission bevel gear sets 34 drive the transmission pressure roller 31 to rotate synchronously. The transmission pressure roller 31, the adjusting cover 53, and the replaceable pressure roller 30 work together to shape the packing.

[0032] Furthermore, such as Figure 7 As shown, a lifting screw 35 is screwed onto the mounting frame 28, a knob is fixedly connected to the lifting screw 35, and a lifting frame 29 that is slidably connected to the mounting frame 28 is screwed onto the lifting screw 35; a plurality of mounting plates with progressively increasing lengths are fixedly connected to the lifting frame 29, and a plurality of replaceable pressure rollers 30 are rotatably connected to a plurality of mounting plates respectively.

[0033] When the height of the replaceable pressure roller 30 is adjusted, the lifting screw 35 is rotated by the knob, and the lifting screw 35 drives the lifting frame 29 to slide up and down along the mounting frame 28. The lifting frame 29 drives the replaceable pressure roller 30 to move up and down through the mounting plate. By increasing the length of multiple mounting plates in sequence, the distance between the replaceable pressure roller 30 and the transmission pressure roller 31 is changed, so that the packing is shaped step by step.

[0034] Furthermore, such as Figure 8 As shown, the output of the transmission bevel gear set 34 is connected to a crank 36, and a connecting rod 37 is rotatably connected to the crank 36. The other end of the connecting rod 37 is rotatably connected to the support cylinder 40. A guide rod 39 is fixedly connected to the support cylinder 40, and a guide block 38 for guiding the guide rod 39 is fixedly connected to the mounting bracket 28.

[0035] When the transmission bevel gear set 34 rotates, it drives the crank 36 to rotate. The crank 36 drives the support cylinder 40 to move through the connecting rod 37. Under the action of the guide rod 39 and the guide block 38, the support cylinder 40 slides along the guide block 38 through the guide rod 39.

[0036] Furthermore, such as Figure 9 and Figure 10 As shown, both the horizontal frame 51 and the vertical frame 48 are fixedly connected to slide rods 45 that are slidably connected to the support cylinder 40, and top springs 49 are sleeved on the slide rods 45; both ends of the support cylinder 40 are rotatably connected to rotating frames 47, and multiple drive rods 46 are rotatably connected to each rotating frame 47. The other end of each drive rod 46 is rotatably connected to a connecting frame 44, and the connecting frame 44 is fixedly connected to the slide rod 45; multiple connecting plates 42 are provided on the outer periphery of the support cylinder 40, and a pair of rotating frames 47 are connected to each other through the connecting plates 42; a fixed rod 41 is fixedly connected to the support cylinder 40, and a movable rod 43 corresponding to the fixed rod 41 is fixedly connected to one of the connecting frames 44; the rotating frame 47 is provided with a fan-shaped groove, and the support cylinder 40 is provided with a support column that cooperates with the fan-shaped groove.

[0037] When the packing needs to be installed between the first roller 50 and the second roller 52, the user can hold the fixed rod 41 and the movable rod 43. The movable rod 43 drives the connecting plate 42 and the rotating frame 47 to rotate. The rotating frame 47 drives the connecting frame 44 to move through the drive rod 46. The connecting frame 44 drives the slide rod 45 to slide along the support cylinder 40. The slide rod 45 drives the corresponding horizontal frame 51 and vertical frame 48 to move, thereby opening the horizontal frame 51 and the vertical frame 48, so that the user can install the packing between the first roller 50 and the second roller 52.

[0038] like Figures 1 to 10 As shown below, the working process of the present invention will be explained in detail.

[0039] When in use, the drive motor 11 is started, and the drive motor 11 drives the connecting wheel 24 to rotate through the connecting shaft 15. The connecting wheel 24 drives one of the braiding wheels 26 to rotate through the upper idler wheel 25. Since the adjacent braiding wheels 26 mesh with each other, the remaining braiding wheels 26 rotate synchronously. The braiding wheels 26 drive the grooved wheel 27 to rotate. The grooved wheel 27 drives the moving rod to move in the groove between the adjacent grooved wheels 27. The moving rod drives the spindle to move along the slide groove, thereby braiding the packing material on the spindle into packing.

[0040] The woven packing flows through the perforations on the soaking pan 3 to the first grooved roller 12, allowing the packing to pass between the first grooved roller 12, the second grooved roller 13, and the take-up pressure roller 14. When the connecting shaft 15 rotates, it synchronously drives the drive wheel 17 to rotate. The drive wheel 17 drives the worm gear 21 to rotate through the driven wheel 18, the first bevel gear set 19, the reducer 16, and the second bevel gear set 20. The worm gear 21 drives the input wheel to rotate through the worm wheel. The input wheel drives the first grooved roller 12 to rotate through the output wheel. The input wheel drives the second grooved roller 13 to rotate through the lower idler wheel 23 and the drive wheel 22. The second grooved roller 13 and the take-up pressure roller 14 work together to transport the packing through the first grooved roller 12 and the second grooved roller 13 to the shaping device 5.

[0041] The geared motor 33 is started, and the geared motor 33 drives multiple transmission bevel gear sets 34 to rotate synchronously through the drive shaft. The multiple transmission bevel gear sets 34 drive the transmission pressure roller 31 to rotate synchronously. The transmission pressure roller 31, the adjusting cover 53, and the replaceable pressure roller 30 work together to shape the packing. At the same time, the transmission bevel gear sets 34 drive the crank 36 to rotate. The crank 36 drives the support cylinder 40 to move through the connecting rod 37. Under the action of the guide rod 39 and the guide block 38, the support cylinder 40 slides along the guide block 38 through the guide rod 39. Under the action of the top spring 49, the first roller 50 and the second roller 52 are in close contact with the packing. When the support cylinder 40 moves, the support cylinder 40 drives the vertical frame 48 and the horizontal frame 51 to reciprocate. The vertical frame 48 flexibly shapes the upper and lower surfaces of the packing through the first roller 50, and the horizontal frame 51 flexibly shapes the front and rear surfaces of the packing through the second roller 52. This allows the compressed packing material to stretch out, thereby reducing the deformation of the packing material and improving the quality of the packing.
