Description

Technical Field

[0001] The utility model relates to the technical field of flexible chains, in particular to a disassembly and assembly tool for flexible chains. Background Art

[0002] In the tobacco processing industry, the production process of the cigarette rolling and packaging workshop is as follows: First, the tobacco is transported to the cigarette machine through the air delivery pipe for cigarette rolling, then the rolled cigarettes are transported from the cigarette machine to the packaging machine for packaging into cigarette boxes, and finally, the cigarette rods packaged into boxes are transported from the packaging machine to the sealing machine for packing and sealing. Among them, the rolled cigarettes are transported from the cigarette machine to the packaging machine, and the cigarette rods packaged into boxes are transported from the packaging machine to the sealing machine. Both of these transportation processes use flexible chains to complete the transportation of cigarettes or cigarette rods.

[0003] The structure of the flexible chain is as follows Figure 4-6 As shown in the figure, several chain plates connected to each other are the main structure of the flexible chain, and the connection between adjacent chain plates is achieved through a connection structure with pin holes and pins. Through such a multi-piece connection, the flexible chain has high tensile strength, can be bent 0-90 degrees during the conveying process, and adapt to different layouts and space restrictions. It is an ideal choice for long conveyors.

[0004] When performing maintenance on the flexible chain, its disassembly and assembly is a particularly critical step. In the existing disassembly and assembly method, it is necessary to align the pin holes on the connecting structures of two adjacent chain plates, and then disassemble and assemble the pins accordingly. During disassembly, due to the mutual tension between the chain plates and the easy shaking of the flexible chain as a whole, it is very difficult to remove the pins; during installation, it is necessary to manually align the pin holes of the two chain plates, which increases the complexity and time cost of the work, and the manual positioning accuracy is not high. Therefore, the existing flexible chain disassembly and assembly method is inefficient and cumbersome to operate, which prolongs the maintenance time of the flexible chain. Utility Model Content

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The structure of the flexible chain 5 is shown in Figure 4-6 , first of all, Figure 6 As shown, the flexible chain 5 includes a plurality of chain plates 51 connected to each other, and each of the two ends of each chain plate 51 is provided with a first connection portion 521 and a second connection portion 522, respectively. The first connection portion 521 and the second connection portion 522 are provided with pin holes, and the axial direction of the pin holes is parallel to the plate surface of the chain plate 51. The number of the first connection portion 521 and the second connection portion 522 is not limited. In this embodiment, one first connection portion 521 and two second connection portions 522 are provided. Figure 5 As shown, when adjacent chain plates 51 are connected, the first connection portion 521 of one chain plate 51 and the second connection portion 522 of the other chain plate 51 are staggered, and the positions of the pin holes on the first connection portion 521 and the second connection portion 522 correspond to each other. In this embodiment, the first connection portion 521 of one chain plate 51 is inserted between the two second connection portions 522 of the other chain plate 51, and the pin holes on the three are controlled to correspond. At this time, the connection between the two chain plates 51 can be completed by a pin 53 inserted in the pin holes of the three connection portions in sequence. For the convenience of explanation, this overall structure including the first connection portion 521 of a chain plate 51 and the second connection portion 522 of the other chain plate 51 is recorded as a connection structure 52. When disassembling and assembling the connection structure 52, it is necessary to take out or install the pins 53 inserted in the pin holes of the three connection portions. Therefore, as shown in FIG. Figure 4 As shown, the portion where the first connection portion 521 or the second connection portion 522 abuts against the end of the pin 53 is referred to as a detachable portion 54 .

[0033] In order to facilitate the assembly and disassembly operation of the flexible chain 5, this embodiment provides an assembly and disassembly tool for the flexible chain, the specific structure of which is as follows:

[0034] See also Figure 1-3 The disassembly and assembly tool comprises at least two clamping structures 1, such as Figure 3As shown, the two clamping structures 1 are respectively connected to two non-adjacent connecting structures 52 (the chain plate 51 and the pin 53 are not shown in the figure), and the connecting structure 52 located between the two clamped connecting structures 52 forms a to-be-disassembled part. In order to achieve clamping, the clamping structure 1 includes two clamping heads 11, and the two clamping heads 11 are respectively in contact with the two disassembly parts 54 of the connecting structure 52; considering the clamping stability, the two clamping heads 11 are arranged on a fixed part 4, and the two clamping heads 11 are respectively arranged at the two ends of the fixed part 4. The disassembly tool also includes a limiting structure 2 for keeping the two connecting structures 52 flush. Among them, the flushing of the connecting structures 52 means that the disassembly parts 54 above the two connecting structures 52 are flush, and the disassembly parts 54 below are also flush. The limiting structure 2 includes a limiting rod 21, and the two ends of the limiting rod 21 are respectively connected to the fixed parts 4 of the two clamping structures 1, and the limiting rod 21 is perpendicular to the pin 53. Under the action of the clamping structure 1 and the limiting rod 21, the two clamped connecting structures 52 are flush with each other and the spacing is fixed, so that when the parts to be disassembled are disassembled, it is not difficult to remove the pins 53 due to the shaking of the flexible chain 5, and when installing, there is no need to manually position the connecting structure 52 to align the pin holes. At this time, the pins 53 on the parts to be disassembled can be easily disassembled and assembled, thereby improving the disassembly and assembly efficiency of the flexible chain 5.

[0035] In some embodiments, the clamp head 11 is preferably a hollow cylindrical structure, and the inner diameter of the clamp head 11 is not less than the outer diameter of the disassembly portion 54. When in use, the disassembly portion 54 is clamped inside the hollow of the clamp head 11. Compared with other clamping methods, this method causes less damage to the flexible chain 5.

[0036] In order to clamp the connection structure 52 of the flexible chain 5 of different specifications, Figure 1-2 As shown, the clamping structure 1 also includes two fixing plates 12 for fixing the two clamp heads 11 respectively. The clamp head 11 and the fixing plates 12 are detachably connected, and different clamp heads 11 can be replaced. Specifically, the detachable connection is preferably a threaded connection, and the fixing plate 12 is provided with a threaded hole 22, and the outer wall of the clamp head 11 is provided with a thread matching therewith.

[0037] In this embodiment, in order to further cope with the connection structures 52 of various flexible chains 5 of different sizes, such as Figure 1 As shown, the limiting structure 2 also includes threaded holes 22 respectively provided on each fixing portion 4; the limiting rod 21 is a threaded rod, including a first threaded segment 211 and a second threaded segment 212 with opposite thread directions, and the first threaded segment 211 and the second threaded segment 212 are respectively threadedly connected to the threaded holes 22 of the two adjacent clamping structures 1. When in use, the spacing between the two clamping structures 1 can be reduced or expanded by rotating the limiting rod 21. Furthermore, in order to fix the spacing after adjustment, the limiting structure 2 also includes at least two locking nuts 23 sleeved on the outside of the limiting rod 21, and the locking nuts 23 are both in contact with the side of the fixing portion 4. Specifically, when two locking nuts 23 are used, according to Figure 1 In the direction of the middle, the two locking nuts 23 respectively abut against the upper sides of the two fixing parts 4, or the two locking nuts 23 respectively abut against the lower sides of the two fixing parts 4; when four locking nuts 23 are used, the four locking nuts 23 respectively abut against the upper and lower sides of the two fixing parts 4.

[0038] In some embodiments, the limiting structure 2 further includes a control block 24 for driving the limiting rod 21 to rotate, and the control block 24 is sleeved on the limiting rod 21. In order to allow the control block 24 to be easily rotated by a wrench or other tools, the control block 24 is preferably an external hexagonal nut.

[0039] In some embodiments, in order to make the distance between the two clamp heads 11 adjustable, the disassembly and assembly tool further includes an adjustment structure 3 for adjusting the distance between the two clamp heads 11, such as Figure 2 As shown, the fixing part 4 includes a first fixing part 41 and a second fixing part 42, and the first fixing part 41 and the second fixing part 42 are connected to the two clamp heads 11 respectively. In order to enable the first fixing part 41 and the second fixing part 42 to slide relative to each other, one fixing part 4 preferably includes two first fixing parts 41, and a slot is provided between the two first fixing parts 41, and the second fixing part 42 is inserted into the slot. The adjustment structure 3 includes a strip groove 32 provided on each first fixing part 41, a through hole 33 provided on each second fixing part 42, an adjustment rod 31 passing through each strip groove 32 and each through hole 33, and a fixing nut 34 sleeved on the adjustment rod 31 for pressing the first fixing part 41 and the second fixing part 42 tightly, wherein the length direction of the strip groove 32 is parallel to the pin 53. When in use, the adjusting rod 31 is slid in the strip groove 32 of the first fixing portion 41. Since the adjusting rod 31 passes through the through hole 33 of the second fixing portion 42 at the same time, the adjusting rod 31 will drive the height of the second fixing portion 42 relative to the first fixing portion 41 to change. In this embodiment, the limiting rod 21 is preferably disposed on the first fixing portion 41.

[0040] In some specific embodiments, the method of disassembling and assembling the flexible chain 5 using the disassembly and assembly tool is as follows: according to the specifications of the flexible chain 5, a suitable clamp head 11 is selected and threadedly connected to the fixing plate 12;

[0041] During disassembly: first loosen the locking nut 23 and adjust the position of the clamping structure 1 on the limiting rod 21. At this time, the distance between the two clamping structures 1 is small. After that, slide the adjusting rod 31 in the strip groove 32 to expand the distance between the two clamp heads 11, and put the left and right connecting structures 52 adjacent to the part to be disassembled between the two clamping structures 1 respectively. Each disassembly part 54 of the two connecting structures 52 is inserted into the hollow inner side of the clamp head 11. At this time, slide the adjusting rod 31 again and fix the position of the adjusting rod 31 by the fixing nut 34, reduce the distance between the two clamp heads 11 so that the part to be disassembled is fixed, and finally use a wrench to rotate the outer hexagonal nut to drive the limiting rod 21 to rotate, control the distance between the two clamping structures 1 to expand, until the part to be disassembled is tightened, and lock it by the locking nut 23 after the adjustment is completed. At this time, the pin 53 on the part to be disassembled can be easily removed to complete the disassembly of the flexible chain 5.

[0042] During installation: first loosen the locking nut 23, then connect the two clamping structures 1 to the two connecting structures 52 in the same way as in the removal step, and finally use a wrench to rotate the outer hexagonal nut to drive the limit rod 21 to rotate, and control the distance between the two clamping structures 1 to narrow or expand until the pin holes of the first connecting part 521 and the second connecting part 522 of the to-be-disassembled part are aligned and located on the same vertical line, and then lock it with the locking nut 23 after the adjustment is completed. At this time, the pin 53 can be easily inserted into the to-be-disassembled part to complete the installation of the flexible chain 5.
