Description
Technical Field
[0001] The utility model relates to the field of conveyor chains, in particular to a flexible guide rail large-pitch conveyor chain. Background Art
[0002] The flexible guide rail large-pitch conveyor chain is a specialized chain designed to address the problem of insufficient meshing between existing conveyor chains and flexible guide rails. Compared to traditional conveyor chains, the flexible guide rail large-pitch conveyor chain features a larger pitch, which helps reduce drag during conveying while improving load capacity and operating efficiency. Furthermore, positioning ridges on the flexible guide rail, designed to match the conveyor chain's unique structure, improve meshing between the chain and the guide rail, effectively preventing chain slippage due to insufficient friction.
[0003] However, when the flexible guide rail large pitch conveyor chain in the existing technology is engaged with the guide rail, the chain links on the chain directly contact the guide rail. Although the rollers on the chain can rotate, the chain links will also slide and rub against the guide rail, causing wear, and the connection force during transportation can easily cause damage to the rollers.
[0004] Therefore, it is necessary to propose a flexible guide rail large pitch conveyor chain to solve the above problems. Utility Model Content
[0005] The main purpose of the utility model is to provide a flexible guide rail large pitch conveyor chain, which can effectively solve the problems in the background technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A flexible guide rail large pitch conveyor chain comprises a plurality of chain links movably connected end to end, wherein the ends of the chain links are interspersed with pins, the outer movable sleeves of the pins are provided with shaft sleeves, the outer movable sleeves of the shaft sleeves are provided with rollers, and the outer ends of the rollers are rotatably connected to swivels protruding from the sides of the chain links;
[0008] It also includes a buffer assembly, which includes a buffer cylinder arranged on the inner side of the roller, the buffer cylinder is movably connected to the outside of the sleeve, a gap is provided between the buffer cylinder and the inner wall of the roller, and a piston rod is evenly arranged around the inner wall of the roller, and a piston cylinder corresponding to the piston rod is evenly arranged around the outer wall of the buffer cylinder, and the end of the piston rod away from the inner wall of the roller is movably connected to the inner side of the piston cylinder.
[0009] Preferably, bearings are fixedly provided on the outer sides of the upper and lower ends of the roller, and the swivel is fixedly connected to the outer wall of the bearing.
[0010] Preferably, a fixing assembly for limiting the pin is inserted into one end of the pin shaft, and the fixing assembly includes a first limiting bent rod and a second limiting bent rod, and the first limiting bent rod and the second limiting bent rod are detachably connected at their adjacent ends.
[0011] Preferably, a first spring is sleeved on the outer side of the piston rod.
[0012] Preferably, a screw is provided at one end of the first limiting bent rod close to the second limiting bent rod, a thread groove is provided at one end of the second limiting bent rod close to the first limiting bent rod, and the screw is threadedly connected to the thread groove.
[0013] Preferably, an abutment block is slidably connected to the inner end of the thread groove, and a second spring is provided between the abutment block and the inner wall of the thread groove.
[0014] Preferably, the length direction of the abutment block is consistent with the length direction of the thread groove.
[0015] Preferably, a limiting groove is provided on the inner wall of the thread groove, and a limiting block that is slidably engaged with the limiting groove is fixedly connected to the side wall of the abutment block.
[0016] Compared with the prior art, the present invention provides a flexible guide rail large pitch conveyor chain, which has the following beneficial effects:
[0017] 1. This flexible guide rail large pitch conveyor chain can create a sliding connection with the guide rail through the swivels that protrude from the side of the chain links when the chain is engaged with the guide rail. The chain links do not contact the guide rail, thus avoiding chain link wear and increasing service life. The buffer components provided can provide buffering protection for the chain links, pins, bushings, and rollers when the chain is running, thus avoiding damage caused by force and further increasing service life.
[0018] 2. The flexible guide rail large pitch conveyor chain facilitates the disassembly of the pin shaft through the set fixing components, which is convenient for the maintenance and replacement of various parts of the chain. The setting of the abutment block and the second spring can increase the stability between the first limit bending rod and the second limit bending rod, reducing the possibility of loosening. The setting of the limit groove and the limit block can prevent the abutment block from rotating when the screw contacts the abutment block, thereby avoiding damage to the second spring.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] like Figure 1-4 As shown, a flexible guide rail large pitch conveyor chain includes a plurality of chain links 1 movably connected at the head and tail ends, a pin 2 is inserted into the end of the chain link 1, a shaft sleeve 7 is provided on the outer movable sleeve of the pin 2, a roller 3 is provided on the outer movable sleeve of the shaft sleeve 7, a swivel 4 protruding from the side of the chain link 1 is provided on the outer sides of both ends of the roller 3, bearings are fixedly provided on the outer sides of the upper and lower ends of the roller 3, and the swivel 4 is fixedly connected to the outer wall of the bearing;
[0026] It also includes a buffer assembly, which includes a buffer cylinder 8 arranged on the inner side of the roller 3, the buffer cylinder 8 is movably connected to the outside of the sleeve 7, a gap is set between the buffer cylinder 8 and the inner wall of the roller 3, and the inner wall of the roller 3 is evenly surrounded by a piston rod 10, the outer wall of the buffer cylinder 8 is evenly surrounded by a piston cylinder 9 corresponding to the piston rod 10, and the end of the piston rod 10 away from the inner wall of the roller 3 is movably connected to the inner side of the piston cylinder 9, and the outer side of the piston rod 10 is sleeved with a first spring 11.
[0027] Furthermore, a fixing component for limiting the pin shaft 2 is inserted into one end of the pin shaft 2, and the fixing component includes a first limiting bent rod 5 and a second limiting bent rod 6, and the first limiting bent rod 5 and the second limiting bent rod 6 are detachably connected at their adjacent ends. A screw 12 is provided at one end of the first limiting bent rod 5 close to the second limiting bent rod 6, and a thread groove 13 is provided at one end of the second limiting bent rod 6 close to the first limiting bent rod 5, and the screw 12 is threadedly connected to the thread groove 13.
[0028] Furthermore, an abutment block 15 is slidably connected to the inner end of the thread groove 13 , a second spring 14 is provided between the abutment block 15 and the inner wall of the thread groove 13 , and the length direction of the abutment block 15 is consistent with the length direction of the thread groove 13 .

When the chain is running, the swivel 4 is in direct contact with the guide rail, and the roller 3 can rotate. The chain link 1 will not rub against the guide rail, thereby increasing the service life. Moreover, when the roller 3 is subjected to force, relative displacement occurs between the piston cylinder 9 and the piston rod 10 to achieve buffering, which cooperates with the first spring 11 to further buffer and reduce damage.
