Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically a variable pitch production line conveyor belt based on detachable chain plates. Background Technology

[0002] A chain conveyor belt is a transmission device that uses standard chain plates as the bearing surface and a motor and reducer as the power transmission. It mainly uses roller chains to drive the chain plates to move, and goods placed on the chain plates are transported and transferred.

[0003] For example, in the case of a hinged conveyor belt with easy disassembly and maintenance (Announcement No. CN220844093U), when it is necessary to disassemble, maintain, or replace a particular chain plate, the screw is unscrewed upwards. After unscrewing the screw, the fixing plate and connecting parts are rotated upwards. After removing all the screws at the top of the chain plate, the chain plate sandwiched in the middle can be removed for replacement. During installation, the fixing plate is connected to the chain plate, and the screw is rotated from top to bottom until it passes through the mounting hole and reaches the threaded hole. The screw and the threaded hole are then threaded together to fix the fixing plate and the chain plate in place.

[0004] The above solution requires unscrewing the screws upwards when disassembling the chain plates on the conveyor belt, then rotating the fixing plate and connecting parts upwards. After all the screws at the top of the chain plates are removed, the shaft is pulled out, and then the chain plate sandwiched in the middle is removed and replaced. During installation, the through holes at the connection of the two sets of chain plates need to be aligned, and the shaft is inserted into the chain plate. However, due to the lack of a positioning mechanism, it is difficult to align the through holes in the two sets of chain plates. Furthermore, because the diameter difference between the through holes in the chain plates and the shaft is small, the shaft cannot penetrate the chain plate when the through holes in the two sets of chain plates are not aligned, thus slowing down the installation speed. Utility Model Content

[0005] The purpose of this invention is to provide a variable-pitch production line conveyor belt based on a detachable chain plate, in order to solve the problem mentioned in the background art that existing chain plate conveyor belts are inconvenient to assemble and disassemble.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a variable-pitch production line conveyor belt based on a detachable chain plate, comprising a chain plate body and pins, wherein a chain body is rotatably connected to both sides of the chain plate body via a rotating shaft; two sets of connecting ears a are fixedly connected to the side of the chain plate body away from the chain body, and connecting ears b are welded and fixed to the side of the chain plate body away from the connecting ears a; both connecting ears a and connecting ears b have an arc-shaped side; a positioning mechanism is provided on one side of the connecting ears b; a pin is penetrated through the interior of the connecting ears b, and one end of the pin is threaded; of the two sets of connecting ears a, one set of connecting ears a has a through hole that penetrates the pin, and the other set of connecting ears a has a threaded hole that is threadedly connected to the pin; a connecting plate is disposed on one side of the chain body, and a limit mechanism is provided on one side of the connecting plate.

[0007] Furthermore, the positioning mechanism includes a spring a fixedly connected inside the connecting ear a, a movable block fixedly connected to one end of the spring a, the end of the movable block being hemispherical, and annular grooves matching the movable block being opened on both sides of the connecting ear b. The outer side of the movable block is slidably connected to the connecting ear a through a slider. The connecting ear a, the spring a, and the movable block constitute an elastic telescopic structure.

[0008] Furthermore, multiple sets of springs a and moving blocks are provided, and the multiple sets of springs a and moving blocks are distributed at equal angles about the central axis of the annular groove.

[0009] Furthermore, the end of the pin away from the thread has an anti-slip groove, and the connecting lug b and the pin form a sliding structure.

[0010] Furthermore, the limiting mechanism includes two sets of insert rods fixedly connected to one side of the connecting plate. The outer side of the insert rods penetrates the chain body. One end of the insert rod is inserted into a limiting plate. Two sets of limiting rods are slidably connected inside the limiting plate, and a spring b is connected between the two sets of limiting rods. One end of the limiting rod is engaged with the insert rod.

[0011] Furthermore, one end of the insertion rod is provided with a slot that matches the limiting rod, and the insertion rod and the limiting rod form a locking mechanism. The inside of the limiting plate is provided with a sliding groove that matches the limiting rod, and the limiting rod and the limiting plate form a sliding structure. The limiting rod is L-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This variable pitch production line conveyor belt based on detachable chain plates can be pulled out as a whole after disengaging from a set of connecting ears a by rotating the pin, so that the two sets of chain plate bodies are disconnected. At this time, the number of chain plate bodies can be adjusted to complete the adjustment of the overall length of the conveyor belt. After the adjustment is completed, the two sets of chain plate bodies can be positioned by the positioning mechanism, so as to connect the two sets of chain plate bodies more quickly. By moving the limiting rod in the limiting mechanism to disengage from the plug rod, and then pulling out the plug rod, the chain plate body can be disassembled.

[0013] 1. By rotating the pin to disengage it from the interior of connecting ear a, the pin can be pulled out as a whole. At this time, the two sets of connected chain plate bodies can be separated. Then, the chain plate bodies can be further removed or added as needed to adjust the overall length of the conveyor belt to adapt to more production situations. After adjustment, the chain plate bodies at both ends of the conveyor belt can be connected and fixed. The positioning mechanism will align the through holes inside the two sets of chain plate bodies and pre-fix the two sets of chain plate bodies, so that the pin can be easily inserted and fixed into connecting ear a and connecting ear b.

[0014] 1. By moving the two sets of limit rods to disengage from the insertion rods, the movable connecting plate can then drive the two sets of insertion rods to disengage from the chain body. At this point, the chain body will disconnect, and the number of chain bodies can be increased or decreased by using the disassembled chain plate body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4 This utility model provides the following technical solution: a variable-pitch production line conveyor belt based on a detachable chain plate, comprising a chain plate body 1 and pins 8. Both sides of the chain plate body 1 are rotatably connected to a chain body 2 via a rotating shaft. Two sets of connecting ears a3 are fixedly connected to the side of the chain plate body 1 away from the chain body 2, and connecting ears b4 are welded and fixed to the side of the chain plate body 1 away from the connecting ears a3. Both connecting ears a3 and connecting ears b4 have an arc-shaped side. A positioning mechanism is provided on one side of the connecting ear b4. A pin 8 is passed through the inside of the connecting ear b4, and one end of the pin 8 is threaded. In one set of connecting ears a3, a through hole is opened inside the connecting ear a3, and the through hole passes through the pin 8. The other set of connecting ears a3... The connecting ear a3 has a threaded hole inside, which is threadedly connected to the pin 8. The positioning mechanism includes a spring a5 fixedly connected inside the connecting ear a3. One end of the spring a5 is fixedly connected to a movable block 6, the end of which is hemispherical. The connecting ear b4 has annular grooves 7 on both sides that match the movable block 6. The outer side of the movable block 6 is slidably connected to the connecting ear a3 via a slider. The connecting ear a3, the spring a5, and the movable block 6 form an elastic telescopic structure. There are multiple sets of springs a5 and movable blocks 6, and the multiple sets of springs a5 and movable blocks 6 are distributed at equal angles about the central axis of the annular groove 7. The end of the pin 8 away from the thread has an anti-slip groove, and the connecting ear b4 and the pin 8 form a sliding structure.

[0024] Please see Figures 1-4This variable-pitch production line conveyor belt based on detachable chain plates allows for disassembly of the chain plate body 1. By rotating the pin 8, the anti-slip groove at one end of the pin 8 increases friction. As the pin 8 rotates, it engages with a set of connecting ears a3 via a threaded connection at one end, thus disengaging from the connecting ears a3. The pin 8 can then be completely removed, separating the two sets of connected chain plate bodies 1. The chain plate bodies 1 can then be further disassembled or added as needed to adjust the overall length of the conveyor belt and accommodate various production conditions. After adjustment, the chain plate bodies 1 at both ends of the conveyor belt can be connected and fixed. First, the two sets of chain plate bodies 1 are joined together. When the connecting ear b4 on one side of one set of chain plate bodies 1 enters between the two sets of connecting ears a3 on the other set of chain plate bodies 1, the connecting ears a3... The moving block 6 of the part will be squeezed, thereby squeezing the spring a5 on one side to contract. When the moving block 6 contacts the annular groove 7 on both sides of the connecting ear b4, the spring a5 will push the moving block 6 to engage with the annular groove 7. Through the engagement of multiple sets of moving blocks 6 with the annular groove 7 on both sides of the connecting ear b4, the positioning of the two sets of chain plate bodies 1 can be completed, so that the through holes inside the two sets of chain plate bodies 1 are aligned. And because the moving block 6 engages with the annular groove 7, the two sets of chain plate bodies 1 will be in a pre-fixed state at this time, and will not move unless subjected to a large external force. Therefore, it is easier to insert the pin 8 into the connecting ear a3 and the connecting ear b4, thereby completing the installation of the two sets of chain plate bodies 1. In this way, the chain plate bodies 1 on the conveyor belt can be easily disassembled and assembled, thereby adjusting the overall length of the conveyor belt.

[0025] Example 2:

[0026] Please see Figure 1 , Figure 5 and Figure 6 Based on Embodiment 1, a chain disassembly structure is also disclosed, the specific structure of which is as follows: a connecting plate 9 is disposed on one side of the chain body 2, and a limiting mechanism is provided on one side of the connecting plate 9. The limiting mechanism includes two sets of insert rods 10 fixedly connected to one side of the connecting plate 9. The outer side of the insert rod 10 penetrates the chain body 2. One end of the insert rod 10 is inserted into a limiting plate 13. Two sets of limiting rods 11 are slidably connected inside the limiting plate 13, and a spring b12 is connected between the two sets of limiting rods 11. One end of the limiting rod 11 is engaged with the insert rod 10. One end of the insert rod 10 is provided with a slot that matches the limiting rod 11. The insert rod 10 and the limiting rod 11 form an engaging mechanism. The limiting plate 13 is provided with a sliding groove that matches the limiting rod 11. The limiting rod 11 and the limiting plate 13 form a sliding structure. The limiting rod 11 is L-shaped.

[0027] Please see Figure 1 , Figure 5 and Figure 6This variable-pitch production line conveyor belt based on detachable chain plates, when disassembling the chain body 2 of the chain plate body 1, moves two sets of limiting rods 11, causing the two sets of limiting rods 11 to compress the spring b12. When the limiting rods 11 disengage from the insert rods 10, the movable limiting plate 13 is moved, causing both ends of the limiting plate 13 to disengage from the insert rods 10. Then, the movable connecting plate 9 moves the two sets of insert rods 10 on one side to disengage from the chain body 2. At this time, the chain body... 2 will be disconnected. The number of chain bodies 2 can be increased or decreased in conjunction with the disassembled chain plate body 1. After adjustment, the insertion rod 10 can be reinserted into the chain body 2. Then, press the two sets of limit rods 11 to move them, and connect the two ends of the limit plate 13 with the two sets of insertion rods 10. After the connection is completed, the limit rod 11 can be released, so that the spring b12 pushes the limit rod 11 to engage with the insertion rod 10, thereby completing the installation of the chain body 2. The above operation makes it easy to disassemble and assemble the conveyor belt chain.
