Description

Technical Field

[0001] The utility model relates to the field of conveyor belt cores, in particular to a flame-retardant new type conveyor belt core. Background Art

[0002] The conveyor belt core is the core structural part of the conveyor belt, usually made of fabric, steel wire or synthetic materials. It provides strength and durability to the belt body and supports the load and tension of the conveyor belt during operation. The material and structure of the core directly affect the carrying capacity, wear resistance and service life of the conveyor belt. Common core materials include polyester and steel wire rope to adapt to different conveying needs and working environments.

[0003] After searching, the Chinese patent "A whole-core flame-retardant conveyor belt with good flame-retardant effect" authorization announcement number is "CN212197135U". The utility model discloses a whole-core flame-retardant conveyor belt with good flame-retardant effect, including a fixed frame plate, a rotating shaft is rotatably installed on the inner side of the fixed frame plate, a conveyor belt is fixedly installed on the outer side of the rotating shaft, and buffer grooves are symmetrically opened at the inner side of the fixed frame plate corresponding to the inner side of the conveyor belt. A spring is fixedly installed at the bottom end of the buffer groove, and a buffer plate is fixedly connected to the top end of the spring. The utility model uses the conveyor belt to facilitate the staff to transport articles. When external objects roll on the surface of the conveyor belt, the conveyor belt is stretched by external impact, resulting in the displacement of the roller and the roller shaft, so that the buffer plate moves down. Through the buffering effect of the spring, the tensile strength of the conveyor belt subjected to external impact can be reduced, thereby avoiding the conveyor belt from being stretched too long due to high-intensity external impact and causing the conveyor belt to break, thereby playing a buffering and protective role for the conveyor belt.

[0004] The above-mentioned spring plays a buffering role when the conveyor belt is subjected to external impact. However, when carrying heavy objects, the spring is easily subjected to a large impact force, causing the spring to break. After the spring breaks, the heavy objects on the conveyor belt will exert pressure on it, causing the conveyor belt to malfunction or be damaged, affecting the stability of operation, thereby increasing maintenance costs and reducing work efficiency.

[0005] Therefore, a flame retardant new type conveyor belt core is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a flame retardant new type conveyor belt core in order to solve the above problems, thereby improving the problem that after the spring breaks, the conveyor belt is easily caused to malfunction or be damaged, thus affecting the stability of operation.

[0007] The present utility model achieves the above object through the following technical solutions. A flame-retardant new conveyor belt core includes: a mounting frame, at the bottom of which two support frames are symmetrically and fixedly connected. At the bottom of the support frames, pulleys are provided. At the top of the mounting frame, two baffles are symmetrically and fixedly connected.

At the bottom of the limiting ring, a spring is fixedly connected. One end of the spring is fixedly connected to the inside of the mounting frame. At the bottom of the limiting ring, two stress blocks are symmetrically and fixedly connected. Inside the mounting frame, a pressure sensor is fixedly connected, and the pressure sensor is located below the stress blocks; an auxiliary mechanism, which is arranged on one side of the inside of the mounting frame; wherein, the auxiliary mechanism includes a mounting shell fixedly connected to one side of the inside of the mounting frame.

On the surface of the fixed sleeve, two first movable rods are symmetrically and movably connected. One end of the first movable rod is hinged to a second movable rod. One end of the second movable rod is hinged to a movable shell. On one side of the movable shell, a positioning shell is fixedly connected. Inside the positioning shell, an auxiliary roller is movably connected. On one side of the positioning shell, a movable sleeve is fixedly connected, and both ends of the movable sleeve are movably connected to the inside of the mounting shell. Through the connecting rod and the spring, when the material presses on the conveyor belt body, the conveyor belt body is buffered. Through the stress block and the pressure sensor, when the spring breaks, an alarm is issued, and then a prompt is sent to the motor through the pressure sensor, thereby driving the motor to work. Through the fixed sleeve, the first movable rod and the second movable rod, the auxiliary roller in the positioning shell is pushed to move, so that the auxiliary roller supports the inner top of the conveyor belt body. Through the movable sleeve, the positioning shell is limited, thus preventing the conveyor belt body from not working properly after the spring breaks and reducing the working efficiency.

[0008] Preferably, the auxiliary mechanism further includes a motor fixedly connected to one side of the mounting plate. The output end of the motor is fixedly connected to a driving rod. One end of the driving rod penetrates through the mounting plate and is rotatably connected to one side of the mounting shell. On the surface of the driving rod, a first gear is fixedly connected. On one side of the first gear, a second gear is engaged. Inside the second gear, a rotating rod is fixedly connected. One end of the rotating rod is rotatably connected to one side of the mounting plate. The other end of the rotating rod penetrates into the inside of the mounting shell and is rotatably connected to one side of the inside of the mounting shell. The surface of the rotating rod is fixedly connected to the inside of the fixed sleeve. Through the motor and the driving rod, the first gear is driven to rotate. Through the first gear and the second gear, the rotating rod and the fixed sleeve are driven to rotate, thereby driving the first movable rod to move.

[0009] Preferably, positioning blocks are fixedly connected to both sides of the movable shell, and one side of the positioning block is fixedly connected to one side of the positioning shell.

[0023] During specific implementation: As Figures 1-4As shown in the figure, a flame-retardant new conveyor belt core includes: a mounting frame 1, two support frames 2 are symmetrically and fixedly connected to the bottom of the mounting frame 1, pulleys 3 are arranged at the bottom of the support frames 2, two baffles 4 are symmetrically and fixedly connected to the top of the mounting frame 1, two rotating shafts 5 are symmetrically arranged in the inner cavity of the mounting frame 1, a conveyor belt body 6 is arranged on the surface of the rotating shafts 5, a roller 7 is arranged in the inner cavity of the mounting frame 1, connecting rods 8 are fixedly connected to both ends of the roller 7, a limiting ring 9 is fixedly connected to the bottom of the connecting rod 8, a spring 10 is fixedly connected to the bottom of the limiting ring 9, one end of the spring 10 is fixedly connected to the inner cavity of the mounting frame 1, two stress blocks 11 are symmetrically and fixedly connected to the bottom of the limiting ring 9, and a pressure sensor 12 is fixedly connected to the inner cavity of the mounting frame 1, and the pressure sensor 12 is located below the stress block 11; an auxiliary mechanism 13, the auxiliary mechanism 13 is arranged on one side of the inner cavity of the mounting frame 1; wherein, the auxiliary mechanism 13 includes a mounting shell 1301 fixedly connected to one side of the inner cavity of the mounting frame 1, a mounting plate 1302 is fixedly connected to one side of the inner cavity of the mounting shell 1301, a fixed sleeve 1308 is arranged in the inner cavity of the mounting shell 1301, two first movable rods 1309 are symmetrically and movably connected to the surface of the fixed sleeve 1308, one end of the first movable rod 1309 is hinged to a second movable rod 1310, one end of the second movable rod 1310 is hinged to a movable shell 1311, a positioning shell 1313 is fixedly connected to one side of the movable shell 1311, an auxiliary roller 1314 is movably connected to the inner cavity of the positioning shell 1313, a movable sleeve 1315 is fixedly connected to one side of the positioning shell 1313, and both ends of the movable sleeve 1315 are movably connected to the inner cavity of the mounting shell 1301. The auxiliary mechanism 13 further includes a motor 1303 fixedly connected to one side of the mounting plate 1302, a driving rod 1304 is fixedly connected to the output end of the motor 1303, one end of the driving rod 1304 penetrates through the mounting plate 1302 and is rotatably connected to one side of the mounting shell 1301, a first gear 1305 is fixedly connected to the surface of the driving rod 1304, a second gear 1306 is meshed with one side of the first gear 1305, a rotating rod 1307 is fixedly connected to the inner cavity of the second gear 1306, one end of the rotating rod 1307 is rotatably connected to one side of the mounting plate 1302, the other end of the rotating rod 1307 penetrates into the inner cavity of the mounting shell 1301 and is rotatably connected to one side of the inner cavity of the mounting shell 1301, and the surface of the rotating rod 1307 is fixedly connected to the inner cavity of the fixed sleeve 1308.

[0024] First, the conveyor belt body 6 receives the materials. During the process of discharging the materials, the gravity of the materials impacts the conveyor belt body 6. At this time, the force received squeezes the spring 10 through the roller 7. When the impact force is too large and causes the spring 10 to break, the roller 7 drives the force-receiving block 11 to press the pressure sensor 12 at the bottom. When the pressure sensor 12 receives a certain degree of pressure, it transmits a signal to the motor 1303. The motor 1303 drives the driving rod 1304 to rotate, causing the driving rod 1304 to drive the first gear 1305 to rotate. Through the cooperation of the first gear 1305 and the second gear 1306, the fixed sleeve 1308 on the surface of the rotating rod 1307 is driven to rotate, and then the first movable rod 1309 is driven to move. Through the cooperation of the first movable rod 1309 and the second movable rod 1310, the auxiliary roller 1314 in the positioning shell 1313 is pushed to move to the inner top of the conveyor belt body 6, so that the auxiliary roller 1314 is in contact with the conveyor belt body 6. The positioning shell 1313 is limited by the movable sleeve 1315. Thus, normal conveying work can be maintained even when the spring 10 breaks, thereby improving work efficiency and reducing maintenance costs.

[0025] As Figure 2 , Figure 3 and Figure 4 shown, positioning blocks 1312 are fixedly connected to both sides of the movable shell 1311. One side of the positioning block 1312 is fixedly connected to one side of the positioning shell 1313. A positioning ring 1316 is fixedly connected to the surface of the motor 1303. One end of the positioning ring 1316 is fixedly connected to one side of the mounting plate 1302. Fixed blocks 1317 are fixedly connected to both sides of the mounting shell 1301. One side of the fixed block 1317 is fixedly connected to one side of the inner cavity of the mounting frame 1. The material of the force-receiving block 11 is rubber. A limiting rod 14 is fixedly connected to the bottom of the limiting ring 9. The surface of the limiting rod 14 is inserted into the inner cavity of the mounting frame 1.

[0026] By setting the positioning blocks 1312, it is convenient to fix the movable shell 1311. By setting the positioning ring 1316, it is convenient to fix and protect the motor 1303. By setting the fixed blocks 1317, it is convenient to fix the mounting shell 1301. With the rubber material of the force-receiving block 11, it is convenient to protect the pressure sensor 12 when squeezing the pressure sensor 12. By setting the limiting rod 14, it is convenient to limit the spring 10.

[0027] When the utility model is in use, first, the conveyor belt body 6 receives materials. During the process of discharging materials, the gravity of the materials impacts the conveyor belt body 6. At this time, the force received squeezes the spring 10 through the roller 7. When the impact force is too large and causes the spring 10 to break, the roller 7 drives the force-bearing block 11 to press the pressure sensor 12 at the bottom. When the pressure sensor 12 receives a certain degree of pressure, it transmits a signal to the motor 1303. The motor 1303 drives the driving rod 1304 to rotate, so that the driving rod 1304 drives the first gear 1305 to rotate. Through the cooperation of the first gear 1305 and the second gear 1306, the fixed sleeve 1308 on the surface of the rotating rod 1307 is driven to rotate, and then the first movable rod 1309 is driven to move. Through the cooperation of the first movable rod 1309 and the second movable rod 1310, the auxiliary roller 1314 in the positioning shell 1313 is pushed to move to the inner top of the conveyor belt body 6, so that the auxiliary roller 1314 is attached to the conveyor belt body 6. The positioning shell 1313 is limited by the movable sleeve 1315. Therefore, normal conveying work can still be maintained in the case of the spring 10 breaking, thereby improving work efficiency and reducing maintenance costs.

[0028] It should be noted that in the above description, the rotating shaft 5, the conveyor belt body 6, the roller 7, the spring 10, the pressure sensor 12, the motor 1303, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the rotating shaft 5, the conveyor belt body 6, the pressure sensor 12, and the motor 1303 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0029] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative method of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
