Description

Technical Field

[0001] The utility model belongs to the technical field of rubber conveyor belt production equipment, in particular to a cutting device for rubber conveyor belt production. Background Art

[0002] Rubber conveyor belts are constructed from multiple layers of rubber-cotton canvas or polyester canvas as a skeleton, covered with high-temperature-resistant or ordinary rubber, bonded together through high-temperature vulcanization. These belts possess a variety of properties, including resistance to heat, wear, burning, oil, alkali, and cold. These properties make them widely used for conveying solid materials in various industries, including mining, metallurgy, steel, coal, hydropower, building materials, chemicals, and grain. Furthermore, their lightweight design, long lifespan, and excellent rubber properties make them particularly suitable for conveying materials over long distances, at high speeds.

[0003] During the production process of rubber conveyor belts, a cutting device is usually used to cut the rubber conveyor belts into different widths and lengths to meet the needs of various conveying equipment. When the rubber conveyor belts are cut by the cutting device, in order to ensure the stability of the rubber conveyor belts, a clamping structure is usually used to fix them to prevent them from shifting during the cutting process.

[0004] The existing clamping structure is generally composed of a cylinder and a clamping plate. The cylinder drives the clamping plate to move toward the side of the rubber conveyor belt, and the side of the rubber conveyor belt is clamped and limited by the clamping plate. In order to ensure the stability of the clamping, the clamping plate is usually made to fit closely with the side of the rubber conveyor belt. Since the rubber conveyor belt has a certain elasticity, when the clamping plate is closely fitted with the side of the rubber conveyor belt, the side of the rubber conveyor belt will be deformed, thereby forming a closer contact with the clamping plate, increasing the friction between the two. This fixing method is relatively stable, but due to the large friction between the two, the pressure on the side of the rubber conveyor belt will increase when the rubber conveyor belt moves, causing certain wear on the side of the rubber conveyor belt, thereby affecting the overall quality. Summary of the Invention

[0012] Optionally, a blanking assembly is further provided on the side of the frame close to the support rod, and the blanking assembly includes a telescopic cylinder 1, a support plate and a blanking plate, one side of the support plate is fixedly connected to one side of the frame, the bottom of the telescopic cylinder 1 is fixedly connected to the top of the support plate, and the output end of the telescopic cylinder 1 is fixedly connected to one side of the blanking plate.

[0037] A cutting component is also provided on the top of the frame 27, which includes a fixed frame 28 and a telescopic cylinder 29.

One end of the telescopic cylinder 29 is fixedly connected to the inner top of the fixed frame 28, and a cutting knife 31 is fixedly provided at the output end of the telescopic cylinder 29. When the telescopic cylinder 29 is started, the cutting knife 31 is pushed toward the direction of the rubber conveyor belt at the top of the frame 27 by the telescopic cylinder 29, thereby realizing cutting of the rubber conveyor belt.

[0038] Working principle:

[0039] When the present invention is used, the rubber conveyor belt to be cut is placed on the top of the frame 27, and the positioning plate 1 is pulled, so that the positioning plate 1 drives the mounting block 9 and the limiting rod 10 set at one end to move. Since both ends of the limiting rod 10 close to the slot 13 are inclined, and the limiting rod 10 is connected to the inner side of the groove 11 through the spring 2 12, when the positioning plate 1 is pulled, the inclined surfaces set at both ends of the limiting rod 10 will be squeezed with the inner side of the slot 13, and when the limiting rod 10 is squeezed, it will move toward the inside of the groove 11. The second spring 12 is compressed. When the limiting rod 10 moves to the position of the other slot 13, the limiting rod 10 is driven to move toward the inside of the slot 13 under the elastic action of the second spring 12. The positioning plate 1 is limited by the cooperation between the limiting rod 10 and the slot 13. In the process of pulling the positioning plate 1, the limiting block 7 provided at one end of the positioning plate 1 away from the limiting rod 10 will slide inside the slide groove 8 provided on the top of the frame 27. The cooperation between the limiting block 7 and the slide groove 8 can prevent the positioning plate 1 from deflecting during the movement.

[0040] By adjusting the positioning plate 1, the roller 6 provided on one side of the positioning plate 1 is fitted with one side of the rubber conveyor belt. When the rubber conveyor belt moves on the top of the frame 27, the rubber conveyor belt is fitted with the outer side of the roller 6, which drives the roller 6 to rotate on the outer side of the support column 5, thereby converting the sliding friction between the rubber conveyor belt and the clamping plate into rolling friction between the roller 6, so that the pressure on the rubber conveyor belt can be dispersed to a wider area, reducing the pressure intensity at each point and alleviating the wear on the side of the rubber conveyor belt.

[0041] At the same time, the position of the roller 6 can be adjusted by the spring 14 provided on one side of the mounting frame 2. When the positioning plate 1 cannot be adjusted to a suitable position, the roller 6 can be squeezed by the rubber conveyor belt to move toward the inside of the receiving groove 3 and squeeze the spring 14. The rebound force of the spring 14 pushes the roller 6 to apply a certain squeezing force to the side of the rubber conveyor belt, thereby limiting the rubber conveyor belt.

[0042] The baffle plate 14 is adjusted to the size of the rubber conveyor belt by the baffle plate 14 provided on the top of the frame 27 to prevent the occurrence of different processing sizes. The motor 18 is started, and the motor 18 drives the threaded column 17 to rotate. Since the movable block 16 is sleeved on the surface of the threaded column 17 and is threadedly connected to the threaded column 17, when the threaded column 17 rotates, it drives the movable block 16 to move inside the limiting groove 19 opened at the top of the fixed rod 15, and drives the baffle plate 14 to move on the top of the frame 27 through the movable block 16, thereby adjusting the position of the baffle plate 14. When the baffle plate 14 moves, it drives the positioning block 22 provided at the other end to slide inside the fixing groove 23 opened at the top of the support rod 21. The cooperation between the positioning block 22 and the fixing groove 23 limits the baffle plate 14 to prevent the baffle plate 14 from deviating and affecting subsequent cutting;

[0043] Start the telescopic cylinder 29, and push the cutting knife 31 toward the rubber conveyor belt on the top of the frame 27 through the telescopic cylinder 29, so as to achieve the cutting of the rubber conveyor belt; after the cutting is completed, the blanking plate 26 is driven to move by the telescopic cylinder 1 24, so that the blanking plate 26 pushes the cut rubber conveyor belt to move toward the side of the frame 27, thereby achieving unloading, so that the cutting knife 31 can continue to cut the next batch of rubber conveyor belts. At the same time, the through groove 30 provided on one side of the fixed frame 28 can prevent the cut rubber conveyor belt from being blocked by the inner side of the fixed frame 28, thereby ensuring smooth unloading.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
