Description

Technical Field

[0001] This utility model belongs to the technical field of packing weaving equipment, specifically relating to a packing weaving device. 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 come with a shaping device, which needs to be purchased separately from other manufacturers, resulting in high costs and large footprints. Therefore, equipment with a shaping device at the take-up outlet has emerged. However, the shaping devices of existing packing braiding machines have 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 and shaping process, the loose and swollen packing material is prone to move backward and accumulate, causing the packing material to become disordered and affecting the overall quality of the packing. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a packing braiding device, which effectively solves the problem that the shaping process of the shaping device of the packing braiding device is too rough, resulting in poor packing shaping quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a packing weaving device, comprising a weaving machine, a shaping device for shaping the packing connected to the weaving machine, the shaping device comprising a mounting frame mounted on the weaving machine, the mounting frame having multiple sets of shaping structures with progressively decreasing shaping dimensions; each of the multiple shaping structures comprising a lifting frame that can slide along the mounting frame, the lifting frame having multiple mounting plates with progressively increasing dimensions fixedly connected to it, and replaceable pressure rollers detachably connected to each of the multiple mounting plates; multiple transmission pressure rollers corresponding to the replaceable pressure rollers being rotatably connected to the mounting frame, and adjustable pressure caps being detachably connected to each of the multiple transmission pressure rollers.

[0007] Furthermore, the mounting bracket includes a fixing plate with fixing holes; a support plate is fixedly connected to the fixing plate, and the fixing plate has reinforcing ribs that cooperate with the support plate.

[0012] Furthermore, the mounting bracket is detachably connected to an adjusting plate with progressively increasing thickness, and multiple adjustable pressure caps are rotatably connected to the adjusting plate.

[0017] A packing braiding device, such as Figure 1-5 As shown, the device includes a braiding machine 1, on which a shaping device 2 for shaping packing is connected. The shaping device 2 includes a mounting frame 3 mounted on the braiding machine 1. The mounting frame 3 is provided with multiple sets of shaping structures with progressively smaller shaping dimensions. Each of the multiple shaping structures includes a lifting frame 4 that can slide along the mounting frame 3. Multiple mounting plates 5 with progressively larger dimensions are fixed to the lifting frame 4. Each of the multiple mounting plates 5 is detachably connected to a replaceable pressure roller 6. Multiple transmission pressure rollers 13 corresponding to the replaceable pressure rollers 6 are rotatably connected to the mounting frame 3. Each of the multiple transmission pressure rollers 13 is detachably connected to an adjustable pressure cap 7.

[0018] In use, this invention involves braiding the packing using a braiding machine 1. The braided packing is then conveyed to a shaping device 2 for shaping, enabling it to be used in critical sealing applications. Specifically, the packing is shaped sequentially using multiple shaping structures with progressively smaller dimensions. This process, from largest to smallest, ensures the packing reaches the standard size, effectively mitigating the problem of reduced packing quality caused by direct and harsh shaping from a single shaping structure. This improves the overall quality of packing shaping in this application.

[0019] When adjusting the shaping structure, firstly, replace the replaceable pressure roller 6 according to the distance between the front and rear surfaces of the packing; secondly, adjust the distance between the replaceable pressure roller 6 and the transmission pressure roller 13 through the lifting frame 4 and the mounting plate 5. As the size of the mounting plate 5 increases sequentially, the distance between the replaceable pressure roller 6 and the transmission pressure roller 13 decreases sequentially until it is equal to the standard size of the packing; finally, install the adjustable pressure cover 7 so that the adjustable pressure cover 7 fits against the replaceable pressure roller 6.

[0020] Furthermore, the mounting frame 3 includes a fixing plate with fixing holes for mounting on the braiding machine 1; a support plate for supporting the lifting frame 4 and the transmission pressure roller 13 is fixedly connected to the fixing plate, and a reinforcing rib for strengthening and stabilizing the support plate is provided on the fixing plate.

[0021] Furthermore, an adjusting screw 14 is rotatably connected to the mounting frame 3, and a knob 15 is fixedly connected to the adjusting screw 14. The lifting frame 4 is screwed to the adjusting screw 14, and the lifting of the lifting frame 4 is adjusted by the knob 15 and the adjusting screw 14. A slider is fixedly connected to the lifting frame 4, and a guide rail is fixedly connected to the mounting frame 3 to guide the slider.

[0022] Furthermore, a mounting screw 16 is rotatably connected to the mounting plate 5, and a stop 17 corresponding to the replaceable pressure roller 6 is fixedly connected to the mounting screw 16. A nut for fixing the replaceable pressure roller 6 is screwed onto the mounting screw 16. The replaceable pressure roller 6 is connected to the mounting screw 16 by means of the nut cooperating with the stop 17. Both the mounting screw 16 and the replaceable pressure roller 6 are provided with keyways, and the mounting screw 16 and the replaceable pressure roller 6 are connected by a key provided in the keyway.

[0023] Furthermore, a geared motor 11 is fixedly connected to the mounting bracket 3. The output end of the geared motor 11 is connected to a synchronous shaft. Multiple sets of bevel gear sets 12 are connected to the synchronous shaft. The output ends of the multiple sets of bevel gear sets 12 are coaxially fixedly connected to multiple transmission pressure rollers 13. The geared motor 11 drives the multiple transmission pressure rollers 13 to rotate synchronously through the synchronous shaft and the multiple sets of bevel gear sets 12.

[0024] Furthermore, the mounting frame 3 is detachably connected to an adjusting plate 9 with progressively increasing thickness, and multiple adjustable pressure covers 7 are rotatably connected to the adjusting plate 9; a spline shaft 8 is fixedly connected to the transmission pressure roller 13, and the adjustable pressure cover 7 is provided with a spline groove that mates with the spline shaft 8; a fixing screw 10 is fixedly connected to the mounting frame 3, and the adjusting plate 9 is provided with a through hole that mates with the fixing screw 10, and a pair of fixing nuts respectively provided on both sides of the adjusting plate 9 are screwed onto the fixing screw 10.

[0025] During installation, the adjustable pressure cover 7 is aligned with the splined shaft 8 and installed, and the through hole on the adjusting plate 9 is aligned with the fixing screw 10 and installed. The adjustable pressure cover 7 is then fitted against the replaceable pressure roller 6, and the adjusting plate 9 is fixed using the fixing nut. As the thickness of the adjusting plate 9 increases sequentially, the distance between the adjustable pressure cover 7 and the transmission pressure roller 13 decreases sequentially, until the distance between the last set of adjustable pressure covers 7 and the transmission pressure roller 13 is equal to the standard size of the packing.

[0026] The working process of this utility model is as follows: In use, the packing is braided by the braiding machine 1, and the braided packing is transported to the shaping device 2 for shaping so that the shaped packing can be used in important sealing applications. The shaping structure is adjusted according to the target size of the packing. First, the replaceable pressure roller 6 is replaced according to the distance between the front and rear surfaces of the packing. The replaceable pressure roller 6 is connected to the mounting screw 16 by a key through the cooperation of the nut and the stop block 17.

[0027] Secondly, the adjustment screw 14 is rotated by the knob 15, and the adjustment screw 14 adjusts the lifting of the lifting frame 4. The lifting frame 4 adjusts the distance between the replaceable pressure roller 6 and the transmission pressure roller 13 through the mounting plate 5. As the size of the mounting plate 5 increases sequentially, the distance between the replaceable pressure roller 6 and the transmission pressure roller 13 decreases sequentially until it is equal to the standard size of the packing.

[0028] Finally, install the adjustable pressure cover 7, aligning the spline groove on the adjustable pressure cover 7 with the spline shaft 8 and installing it. Align the through hole on the adjusting plate 9 with the fixing screw 10 and install it. Make the adjustable pressure cover 7 fit against the replaceable pressure roller 6, and fix the adjusting plate 9 with the fixing nut. As the thickness of the adjusting plate 9 increases sequentially, the distance between the adjustable pressure cover 7 and the transmission pressure roller 13 decreases sequentially, so that the distance between the last set of adjustable pressure covers 7 and transmission pressure roller 13 is equal to the standard size of the packing.

[0029] The shaping process is as follows: The geared motor 11 is started, which drives the synchronous shaft to rotate. The synchronous shaft drives multiple transmission pressure rollers 13 to rotate synchronously through multiple sets of bevel gear sets 12. The transmission pressure rollers 13, replaceable pressure rollers 6, and adjustable pressure caps 7 work together to compress and shape the packing. The packing is shaped sequentially through 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 packing quality degradation caused by direct and rough shaping by a single shaping structure, and improves the quality of packing shaping in this application.
