Description

Technical Field

[0001] The utility model relates to the technical field of chain plate machines, in particular to a conveying mechanism of a chain plate machine. Background Art

[0002] In industrial production, chain conveyors are widely used in industries such as food processing, chemicals, and metallurgy due to their efficient and stable material transport capabilities. The conveying mechanism of a chain conveyor primarily uses a driving and driven component on the frame to drive the chain and chain plates, achieving continuous material transport. However, over long-term use, the chain is subject to the risk of breakage due to factors such as alternating stress, wear, and fatigue.

[0003] When a chain in a chain conveyor mechanism breaks, the material being conveyed will, on the one hand, lose the chain's traction and slip, causing not only material loss but also possible production accidents. On the other hand, the driving and driven components of the conveyor mechanism continue to idle under the motor's drive, causing excessive wear on equipment components, shortening equipment life, and even causing more serious mechanical failures. Currently, most existing chain conveyor mechanisms lack rapid detection and braking mechanisms for chain breaks, making it difficult to take timely action at the moment of chain breakage and effectively preventing the occurrence of these problems.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0026] A chain conveyor mechanism, see attached Figure 1 and attached Figure 2As shown, it includes a frame 1, an active part 2 and a driven part 21 are installed on the frame 1, a chain 22 is connected to the active part 2 and the driven part 21, and a chain plate 23 is installed on the chain 22. Among them, the specific installation structure of the frame 1, the active part 2, the driven part 21, the chain 22 and the chain plate 23 is the existing technology, and the present utility model does not repeat it; the improvement of the present utility model is that the frame 1 is further provided with a mounting frame 3, the mounting frame 3 is provided with a rebound component 4, the rebound component 4 is connected to a trigger component 5, and the trigger component 5 is used to conflict with the chain 22. It is also electrically connected to the active part 2. The rebound component 4 makes the trigger component 5 contact with the chain 22 under normal conditions. When the chain 22 breaks, the trigger component 5 triggers a signal due to the disappearance of the action of the chain 22. The mounting frame 3 is also provided with a telescopic component 6. The telescopic component 6 is electrically connected to the trigger component 5, and the telescopic component 6 is connected to the friction plate 7. The friction plate 7 is on the side of the driven wheel of the driven part 21. When the chain 22 breaks, the trigger component 5 signal is triggered, causing the active part 2 to stop driving the motor. At the same time, the telescopic component 6 drives the friction plate 7 to brake the driven wheel of the driven part 21.

[0027] During the specific implementation of the present invention, during normal operation, the rebound component 4 is in a certain state so that the trigger component 5 contacts the chain 22. When the chain 22 breaks, the effect of the chain 22 on the trigger component 5 disappears. At this time, the trigger instruction is triggered, and the active part 2 drives the motor to stop moving. At the same time, the telescopic component 6 drives the friction plate 7 to brake the driven wheel of the driven part 21. The friction plate 7 directly acts on the driven wheel of the driven part 21 to quickly stop the operation of the conveying mechanism, thereby achieving timely braking of the conveying mechanism when the chain 22 breaks, avoiding problems such as material slipping and equipment idling caused by the breakage of the chain 22. When in use, the trigger component 5 contacts the chain 22 during normal operation, triggering the brake when it breaks, and the operation can be resumed after reset after repair.

[0028] In the above scheme, specifically, refer to the attached Figure 2 As shown, the rebound assembly 4 includes a guide rod 41, which has two guide rods 41 and is vertically arranged on the mounting frame 3. The two guide rods 41 are slidably fitted with a movable seat 42 for mounting the trigger assembly 5. A telescopic spring 43 is provided under the movable seat 42, and the telescopic spring 43 is sleeved on the outside of the guide rod 41. A limit seat 44 is installed on the guide rod 41, and the limit seat 44 is located above the movable seat 42.

[0029] In the scheme, during normal operation, the chain 22 contacts the trigger component 5, causing the movable seat 42 to compress the telescopic spring 43 to a certain height position. At the moment the chain 22 breaks, the trigger component 5 loses contact, and the elastic force of the telescopic spring 43 drives the movable seat 42 to move upward along the guide rod 41, realizing the mechanical signal conversion and transmission of the broken state of the chain 22, ensuring the sensitive response and stable reset of the trigger component 5 to the state change of the chain 22.

[0030] In addition, considering that the limit position can be adjusted during the upward movement of the movable seat 42, for this purpose, refer to the attached Figure 3 As shown, the guide rod 41 is a threaded rod, the limiting seat 44 is a nut, and the movable seat 42 and the guide rod 41 are slidably matched through a linear sleeve 45 .

[0031] In the scheme, the guide rod 41 is designed as a threaded rod, the limit seat 44 adopts a nut, and the linear sleeve 45 between the movable seat 42 and the guide rod 41 is used to realize the limit adjustment. The linear sleeve 45 ensures that the movable seat 42 slides stably on the guide rod 41 without being affected by the thread of the threaded rod, and the nut can be screwed up and down along the threaded rod. By changing the position of the nut on the threaded rod, the limit point of the movable seat 42 when moving upward can be flexibly adjusted.

[0032] For the above solution, specifically, refer to the attached Figure 3 As shown, the trigger assembly 5 includes a pressure sensor 51 , which is mounted on the movable seat 42 . A fixing frame 52 is provided on the pressure sensor 51 , and a rotating roller 53 for contacting the chain 22 is mounted on the fixing frame 52 .

[0033] In the scheme, when the chain 22 operates normally, the rotating roller 53 rolls with the chain 22 to reduce contact wear and transmit the pressure of the chain 22 to the pressure sensor 51. Once the chain 22 breaks, the rotating roller 53 loses the limit of the chain 22, and the pressure sensor 51 detects a sudden drop in pressure, triggering a signal to stop the driving motor of the active part 2 and, at the same time, start the telescopic component 6 to drive the friction plate 7 to brake the driven wheel of the driven part 21.

[0034] For the above solution, specifically, refer to the attached Figure 2 As shown, the telescopic assembly 6 includes a fixed plate 61, which is arranged on the mounting frame 3, and a telescopic cylinder 62 and a slide rod 63 are installed on the fixed plate 61. The telescopic cylinder 62 adopts one of the air cylinder, hydraulic cylinder or electric cylinder in the prior art, and the ends of the telescopic cylinder 62 and the slide rod 63 are commonly connected to a fixed seat 64 for mounting the friction plate 7. A buffer spring 65 is provided between the fixed seat 64 and the mounting frame 3, and the buffer spring 65 is sleeved on the slide rod 63.

[0035] In the scheme, when the trigger assembly 5 sends a signal that the chain 22 is broken, the telescopic cylinder 62 acts quickly, pushing the fixed seat 64 to move along the slide rod 63 toward the driven wheel of the driven part 21, so that the friction plate 7 is in contact with the driven wheel to implement braking. The buffer spring 65 between the fixed seat 64 and the mounting frame 3 is sleeved on the slide rod 63. At the moment when the friction plate 7 contacts the driven wheel, the buffer spring 65 can absorb part of the impact force to avoid damage to the driven wheel and the friction plate 7 caused by rigid collision. At the same time, the contact pressure between the friction plate 7 and the driven wheel is adjusted through elastic deformation, making the braking process smoother and more reliable.

[0036] In the above scheme, the linkage between the trigger component 5 and the telescopic component 6 is taken into consideration. Figure 4 and attached Figure 5 As shown, the telescopic assembly 6 is equipped with a docking assembly 8 for contacting the trigger assembly 5, and when the trigger assembly 5 is connected with the docking assembly 8, the telescopic assembly 6 operates; specifically, the docking assembly 8 includes a mounting rod 81, the mounting rod 81 is arranged on the fixing plate 61, and the end of the mounting rod 81 is equipped with a limit switch 82 for contacting the fixing frame 52.

[0037] Among them, when the chain 22 is operating normally, the fixed frame 52 of the trigger component 5 is at a certain height position under the action of the chain 22, and remains separated from the limit switch 82 of the docking component 8. At this time, the telescopic component 6 does not move. Once the chain 22 breaks, the movable seat 42 moves up along the guide rod 41 under the action of the telescopic spring 43, and the fixed frame 52 of the trigger component 5 moves accordingly until it contacts and triggers the limit switch 82. After the limit switch 82 is triggered, a signal is sent to the telescopic component 6 to start the telescopic cylinder 62, driving the friction plate 7 to brake the driven wheel; this design realizes the precise linkage between the trigger component 5 and the telescopic component 6, ensuring that the telescopic component 6 can respond quickly and perform the braking action at the moment the chain 22 breaks, avoiding braking failure due to signal transmission delay or error, and ensuring the reliability and timeliness of the safety protection system of the chain plate 23 conveying mechanism.

[0038] For the above scheme, refer to the attached Figure 6 As shown, an audible and visual alarm 9 is provided on the mounting frame 3 , and the audible and visual alarm 9 is electrically connected to the trigger component 5 . When the trigger component 5 is triggered by a signal, the audible and visual alarm 9 performs an alarm action.

[0039] Among them, when the chain 22 is operating normally, the trigger component 5 is in a stable state of being resisted by the chain 22, no trigger signal is generated, and the sound and light alarm 9 remains on standby. Once the chain 22 breaks, the trigger component 5 changes its displacement due to the loss of the resistance of the chain 22. The pressure sensor 51 detects the sudden drop in pressure and immediately generates an electrical signal and transmits it to the sound and light alarm 9. After receiving the signal, the sound and light alarm 9 starts, and by flashing lights and sounding alarms, it intuitively feeds back the chain 22 breakage fault to the operator, so that the operator can quickly detect the abnormality, shut down the machine for maintenance in time, and avoid the expansion of the fault.
