Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a limiting device for belt conveyors. Background Technology

[0002] A belt conveyor is a mechanical device that uses the continuous movement of a belt to transfer materials. It is widely used in industrial production, logistics and transportation and other fields.

[0003] During the operation of existing belt conveyors, belt misalignment may occur, which not only affects the conveying accuracy and efficiency of materials, but may also lead to problems such as accelerated belt wear and equipment failure.

[0004] The existing patent (publication number: CN222180724U) provides a limiting device for a belt conveyor, including mounting bases disposed on opposite sides of the conveyor. Several mounting bases are spaced apart along the conveying direction of the conveyor. Two limiting wheels are horizontally arranged side by side on each mounting base. The belt passes through the limiting grooves of the limiting wheels on both sides. The two limiting wheels are detachably mounted on the mounting base by pins. This limiting device can prevent the belt from running off-center and rubbing against the side plates, bearing fixing bolts, etc., causing burrs, damage, and falling into the tobacco leaves, eliminating the quality hazards of belt debris and increasing the service life of the belt.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing belt conveyors lack limiting devices for the conveyed materials, which makes it easy for the conveyed materials to fall off the side or become skewed due to factors such as vibration. Although some belt conveyors install two limiting baffles on both sides of the conveyor belt with bolts, the distance between the two limiting baffles is not easy to adjust quickly according to the width of the conveyed materials, and it is also inconvenient to clean the conveyor belt.

[0006] Therefore, a limiting device for belt conveyors is proposed. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A limiting device for a belt conveyor includes a belt conveyor body 1, a limiting component 2 is provided on the top of the belt conveyor body 1, and a cleaning component 3 is provided on the bottom of the belt conveyor body 1.

[0029] The limiting component 2 includes a spiral frame 201. The spiral frame 201 is fixedly connected to the frame of the belt conveyor body 1 on the side closest to the frame of the belt conveyor body 1. A turntable 202 is provided on the top left side of the spiral frame 201. A bidirectional screw 203 is fixedly connected to the right side of the turntable 202. The right side of the bidirectional screw 203 extends through to the right side of the spiral frame 201. The side of the surface of the bidirectional screw 203 closest to the inner wall of the spiral frame 201 is rotatably connected to the inner wall of the spiral frame 201 through a bearing. Both sides of the surface of the bidirectional screw 203 are threadedly connected to internal thread blocks 204. Limiting baffles 205 are fixedly connected to the bottom of the two internal thread blocks 204.

[0030] In this embodiment, by setting up a belt conveyor body 1, a limiting component 2, and a cleaning component 3, the belt conveyor body 1 can transport materials. The limiting component 2 limits the material on both sides during transport, preventing it from falling off the sides of the conveyor belt or becoming skewed, ensuring the material is always transported in a straight line. The spacing of the limiting components can be easily and quickly adjusted according to the width of the material, thus improving flexibility and convenience. The cleaning component 3 allows for easy cleaning of the conveyor belt surface during operation, simplifying maintenance for operators.

[0031] Specifically, such as Figure 2 , Figure 4As shown, the cleaning component 3 includes a lifting air rod 301, which is fixedly connected to the bottom of the U-shaped frame 201. The output rod of the lifting air rod 301 extends through the inner side of the U-shaped frame 201 and is fixedly connected to a fixing plate 302. The top of the fixing plate 302 is provided with cleaning bristles 303. The bottom sides of the fixing plate 302 are fixedly connected with first limiting rods 304, and the bottom of the first limiting rods 304 extends through the bottom of the U-shaped frame 201.

[0032] Specifically, such as Figure 4 As shown, the bottom of the U-shaped frame 201 is provided with a through hole 4 for use with the lifting air rod 301, and the output rod surface of the lifting air rod 301 is slidably connected to the inner wall of the through hole 4.

[0033] Specifically, such as Figure 4 As shown, the bottom of the U-shaped frame 201 has first sliding holes 5 on both sides for use with the first limiting rod 304, and the surface of the first limiting rod 304 is slidably connected to the inner wall of the first sliding hole 5.

[0034] In this embodiment: by setting up a lifting air rod 301, a fixed plate 302, cleaning bristles 303, a first limiting rod 304, a through hole 4, and a first sliding hole 5, when the conveyor belt of the belt conveyor body 1 needs to be cleaned during operation, the lifting air rod 301 can be activated, causing the output rod of the lifting air rod 301 to extend and drive the fixed plate 302 to move upward, so that the fixed plate 302 drives the cleaning bristles 303 to adhere to the lower surface of the conveyor belt of the belt conveyor body 1, and the cleaning work of the running conveyor belt can be carried out by the cleaning bristles 303, which is relatively convenient. The setting of the first limiting rod 304 can guide and limit the fixed plate 302, so that the fixed plate 302 will not shake. The setting of the through hole 4 allows the output rod of the lifting air rod 301 to pass through the loop frame 201 for telescopic transmission. The setting of the first sliding hole 5 allows the first limiting rod 304 to pass through the loop frame 201 for up and down sliding.

[0035] Specifically, such as Figure 2 , Figure 4 As shown, a limiting groove 6 is provided on the top of the inner side of the spiral frame 201 to cooperate with the internal thread block 204. The side of the internal thread block 204 near the inner wall of the limiting groove 6 is slidably connected to the inner wall of the limiting groove 6.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, the front and rear sides of the two limiting baffles 205 are fixedly connected to the second limiting rods 7, and the front and rear sides of the top of the belt conveyor body 1 are fixedly connected to the limiting blocks 8. The side of the second limiting rod 7 away from the limiting baffle 205 passes through the limiting block 8. The side of the limiting block 8 near the limiting baffle 205 is provided with a second sliding hole 9 that cooperates with the second limiting rod 7. The surface of the second limiting rod 7 is slidably connected to the inner wall of the second sliding hole 9.

[0037] In this embodiment: by setting the limiting groove 6, the internal thread block 204 can be guided and limited, so that the internal thread block 204 can move smoothly left and right under the transmission of the bidirectional screw 203. By setting the second limiting rod 7 and the limiting block 8, the limiting baffle 205 can be auxiliary supported and guided and limited, so that the limiting baffle 205 can be stably adjusted in the left and right position. By setting the second sliding hole 9, the second limiting rod 7 can pass through the limiting block 8 to slide left and right.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, support plates 10 are provided on the front and rear sides of the inner sides of the frame of the belt conveyor body 1. A limit roller 11 is rotatably connected to the side of the support plate 10 closest to the conveyor belt of the belt conveyor body 1. The limit roller 11 is in contact with the conveyor belt of the belt conveyor body 1.

[0039] Specifically, such as Figure 5 As shown, the front and rear sides of the inner sides of the frame of the belt conveyor body 1 are provided with mounting grooves 12 that cooperate with the support plate 10. The side of the support plate 10 near the inner wall of the mounting groove 12 is fixedly connected to the inner wall of the mounting groove 12.

[0040] In this embodiment: by setting the support plate 10, the limiting roller 11 can be supported and positioned. By setting the limiting roller 11, the conveyor belt of the belt conveyor body 1 can be limited, which can prevent the conveyor belt from running off-center and rubbing against the frame. By setting the mounting groove 12, the support plate 10 and the frame of the belt conveyor body 1 can be installed conveniently without affecting the operation of the conveyor belt of the belt conveyor body 1.

[0041] Working principle: When the belt conveyor body 1 conveys materials, two limit baffles 205 can limit the materials on both sides to prevent them from falling off the sides of the conveyor belt or becoming skewed, ensuring that the materials are always conveyed in a straight line. Furthermore, by rotating the turntable 202 in either the forward or reverse direction, the turntable 202 drives the bidirectional screw 203 to rotate in either direction. This forward or reverse rotation of the bidirectional screw 203 causes two internal threaded blocks 204 to move simultaneously in opposite directions through the threads and under the limiting guidance of the limit groove 6. The two limit baffles 205 will move in opposite or opposite directions, which allows for quick and easy adjustment of the distance between the two limit baffles 205 according to the width of the material, thereby improving the flexibility and convenience of use. When the conveyor belt of the belt conveyor body 1 needs to be cleaned during operation, the lifting air rod 301 can be activated, causing the output rod of the lifting air rod 301 to extend and drive the fixed plate 302 to move upward. This causes the fixed plate 302 to drive the cleaning brush 303 to adhere to the lower surface of the conveyor belt of the belt conveyor body 1, allowing the cleaning brush 303 to clean the running conveyor belt, which is quite convenient.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
