Description

Technical Field

[0001] The invention belongs to the technical field of conveyor belts, in particular to a skirt conveyor belt for material transmission. Background Art

[0002] A skirt conveyor belt is a special type of conveyor belt. The skirt is usually made of rubber or other soft materials and fixed to the edge of the conveyor belt to form a closed edge. The skirt conveyor belt can prevent the conveyed material from overflowing from the side during transportation, ensuring that the material remains in the belt during transportation. It can also reduce the contact between the material and the external environment and prevent external pollutants from entering the material, thereby ensuring the quality and hygiene of the material. Skirt conveyor belts are usually used to convey materials that are easy to scatter or flow, such as powdery materials, granular materials, fluid materials, etc., and are especially suitable for inclined upward conveying conditions.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figures 1 to 6 As shown, a skirt conveyor belt for material transmission according to an embodiment of the present invention comprises a conveyor, a conveyor belt and a tensioning assembly;

[0035] The conveyor comprises an inclined casing 1; a support frame 2 is fixedly connected to the lower side of the casing 1; a driving roller and a group of driven rollers are rotatably connected inside the casing 1, and the driving roller is driven by a power device 3;

[0036] The conveyor belt comprises a belt body 4; a pair of wavy skirts 5 are fixedly connected to the surface of the belt body 4, and the skirts 5 are elastic; a group of baffles 6 are evenly distributed on the surface of the belt body 4 between the skirts 5; the skirts 5 and the baffles 6 are both prior arts well known to those skilled in the art, and are not fully shown in the figure, only a part of them is shown;

[0037] The tensioning assembly includes a pair of arc-shaped pads 7, and the pair of pads 7 are fixedly connected to the inner side of the top of the housing 1; a group of pull rods 8 are evenly distributed on both sides of the belt body 4; the top of the pull rod 8 is fixedly connected to the top of the skirt 5; the bottom of the pull rod 8 is connected to a connecting rod 9; the end of the connecting rod 9 is rotatably connected to a roller 10, and the roller 10 and the inner side of the housing 1 are in contact with each other;

[0038] A group of mounting blocks 11 are evenly distributed on both sides of the belt body 4; the pull rod 8 and the mounting shell are hinged by a turn pin 12; the pull rod 8 and the connecting rod 9 are hinged by an ear plate 13 and a turn pin 2 14; the turn pin 12 and the turn pin 2 14 are both connected with torsion springs; the angle between the pull rod 8 and the connecting rod 9 is limited by the torsion spring, so that the connecting rod 9 remains horizontal.

[0039] The skirt 5 conveyor belt in the prior art is combined by setting the skirt 5 and the baffle 6, which can improve the conveying efficiency and effectively prevent the material from overflowing from the side. However, due to the existence of the skirt 5 and the fact that the skirt 5 is usually wavy, the conveyor belt is not smooth when unloading, especially when facing muddy and pasty materials, such as sludge, colloid, etc. When the conveyor belt moves to the end of the conveyor for unloading, the material is easy to adhere to and remain inside the wavy skirt 5, resulting in incomplete unloading. The present invention sets a tensioning component, and the roller 10 can roll inside the casing 1 during the movement of the conveyor belt. When the belt body 4 moves to the top of the casing 1, the skirt 5 is squeezed by the driven roller. It will open along its length direction. At the same time, the roller 10 rolls to the surface of the protruding pad 7, and the distance between the roller 10 and the casing 1 increases. The connecting rod 9 presses the lower end of the pull rod 8 toward the inner side of the belt body 4, causing the pull rod 8 to rotate on the side of the belt body 4, and then the upper end of the pull rod 8 moves toward the outside of the belt body 4, and stretches and deforms a pair of skirts 5 to both sides, increasing the distance between the pair of skirts 5, so that the skirts 5 can be opened in both longitudinal and transverse directions, reducing the obstruction of the skirts 5 on the materials, and improving the efficiency of the materials falling downward from the surface of the belt body 4. At the same time, it is conducive to promoting the separation of the materials from the inside of the wavy skirt 5, reducing the residue of the materials on the surface of the skirt 5, and improving the unloading efficiency of the conveyor belt.

[0040] A group of notches 15 are evenly distributed on both sides of the belt body 4; the mounting block 11 is fixedly connected to the inside of the notch 15; by setting the notch 15, the mounting block 11, the pull rod 8 and the rotating pin 12 are all installed inside the notch 15, so that they do not protrude from the side of the belt body 4 to prevent them from colliding with other parts of the conveyor during operation.

[0041] Transition portions 16 are provided at both ends of the cushion block 7; the thickness of the transition portion 16 gradually decreases from the cushion block 7 to the housing 1; by providing the transition portion 16, the movement of the roller 10 is guided, so that the roller 10 moves from the housing 1 to the surface of the cushion block 7 more smoothly, thereby improving the stability of the equipment operation.

[0042] A group of grooves 17 are evenly distributed on the surface of the pad 7, and the cross-section of the grooves 17 is arc-shaped; in the process of the roller 10 rolling on the surface of the pad 7, when it rolls to the grooves 17, the distance between the roller 10 and the casing 1 is reduced, driving the pull rod 8 to rotate a certain angle, so that the upper end of the pull rod 8 drives the skirt 5 to return slightly to the inside of the belt body 4, and when the roller 10 passes over the grooves 17, the distance between the roller 10 and the casing 1 increases again, and the upper end of the pull rod 8 again tensions the skirt 5 toward the outside of the belt body 4. By setting a plurality of grooves 17, the skirt 5 is continuously tensioned and swung back and forth, thereby further improving the efficiency of material separation from the inside of the skirt 5 and shaking off the material adhering to the surface of the skirt 5.

[0043] Embodiment 2: Figures 7 and 8As shown, in contrast to Example 1, another implementation of the present invention is: an elastic core layer 18 is fixedly connected inside the skirt 5, and the material of the core layer 18 can be a polymer material, such as polyamide, polytetrafluoroethylene, etc., or a metal material, such as steel, aluminum, copper, nickel alloy, etc.; by arranging the core layer 18 inside the skirt 5 as the skeleton of the skirt 5, the skirt 5 is further elastically supported, thereby improving its deformation recovery ability, so that the skirt 5 can still be restored to its original state after multiple tensioning deformations, thereby extending the service life of the skirt 5.

[0044] Elastic sealing parts 19 are fixedly connected between the two ends of the baffle 6 and the skirt 5. The material of the sealing parts 19 can be rubber, silicone, polyurethane, etc.; by setting the sealing parts 19, on the one hand, the gap between the baffle 6 and the skirt 5 is blocked to prevent the material from overflowing downward through the gap during the conveying process; on the other hand, the skirt 5 can stretch and deform the sealing parts 19 when it is stretched outward, thereby reducing the constraint of the baffle 6 on the skirt 5, so that the skirt 5 can be stretched smoothly.

[0045] A pair of connecting members 20 are fixedly connected in the recessed portion on one side of the skirt 5 that is away from each other; the ends of the connecting members 20 are fixedly connected to magnetic blocks 21, and the pair of magnetic blocks 21 are attracted to each other; when the belt body 4 moves to the top of the casing 1, under the squeezing action of the driven roller, the skirt 5 opens along its length direction. In this process, since the pair of magnetic blocks 21 are attracted to each other, a force accumulation effect is generated during the opening process of the skirt 5. When the opening force is greater than the magnetic attraction force, the pair of magnetic blocks 21 separate from each other, and the recessed portion of the skirt 5 is accelerated to open to both sides, resulting in a setback effect, thereby increasing the opening force of the skirt 5 and further reducing the residue of material on the surface of the skirt 5.

[0046] An arc-shaped elastic strip 22 is fixedly connected to the surface of the connecting member 20; a billiard ball 23 is fixedly connected to one end of the elastic strip 22 close to the skirt 5; as the pair of magnetic blocks 21 separate, the billiard ball 23 can repeatedly hit the surface of the skirt 5 under the action of its own inertia and the elastic force of the elastic strip 22, causing the skirt 5 to vibrate and shake off the material on its surface, further improving the separation efficiency between the material and the skirt 5 and preventing the material from adhering to the surface of the skirt 5.

[0047] An arc-shaped elastic membrane 24 is fixedly connected in the recessed part on one side of the skirt 5 away from each other, and a closed cavity is formed between the elastic membrane 24 and the skirt 5; a spring sheet 25 is fixedly connected to the inner side of the elastic membrane 24, and the material of the spring sheet 25 can be the same as that of the core layer 18; a group of guide holes 26 are evenly distributed on the surfaces of the elastic membrane 24 and the spring sheet 25; when the skirt 5 is opened along its length direction, the elastic membrane 24 is stretched and deformed, and the external air is sucked into the closed cavity between the elastic membrane 24 and the skirt 5 through the guide holes 26. When the recessed part of the skirt 5 shrinks and resets to the middle, the spring sheet 25 drives the elastic membrane 24 to recover and bend again, and then squeezes the air inside it outward through the guide holes 26, blowing the magnetic block 21, the elastic bar 22 and the billiard ball 23 surface, removing dust and other impurities on the surface, ensuring its good working efficiency, and preventing the problem of dust adhering to the surface of the magnetic block 21 affecting the suction effect, so that it can be smoothly sucked together again.

[0048] Working principle: By setting up a tensioning component, the roller 10 can roll inside the casing 1 during the movement of the conveyor belt. When the belt body 4 moves to the top of the casing 1, the skirt 5 will open along its length direction under the squeezing action of the driven roller. At the same time, the roller 10 rolls to the surface of the protruding pad 7, and the distance between the roller 10 and the casing 1 increases. Then the connecting rod 9 presses the lower end of the pull rod 8 toward the inside of the belt body 4, causing the pull rod 8 to rotate on the side of the belt body 4, and then the upper end of the pull rod 8 moves toward the outside of the belt body 4, and the pair of skirts 5 are tensioned and deformed to both sides, increasing the distance between the pair of skirts 5, so that the skirts 5 can be opened in both longitudinal and transverse directions, reducing the obstruction of the skirts 5 on the materials and increasing the materials falling downward from the surface of the belt body 4. The roller 10 is used to move the material from the inner part of the wavy skirt 5 to the outer part of the belt body 4, thereby reducing the residual material on the surface of the skirt 5 and improving the unloading efficiency of the conveyor belt. When the roller 10 rolls on the surface of the pad 7, when it rolls to the groove 17, the distance between the roller 10 and the casing 1 is reduced, driving the pull rod 8 to rotate a certain angle, so that the upper end of the pull rod 8 drives the skirt 5 to return slightly to the inner side of the belt body 4. When the roller 10 passes the groove 17, the distance between the roller 10 and the casing 1 increases again, and the upper end of the pull rod 8 again pulls the skirt 5 to the outer side of the belt body 4. By setting a plurality of grooves 17, the skirt 5 is continuously pulled back and shaken, which further improves the efficiency of the material from the inner part of the skirt 5 and shakes off the material adhering to the surface of the skirt 5.

[0049] When the belt body 4 moves to the top of the casing 1, the skirt 5 opens along its length direction under the squeezing action of the driven roller. In this process, since the pair of magnetic blocks 21 are attracted to each other, a force storage effect is generated during the opening process of the skirt 5. When the opening force is greater than the magnetic attraction force, the pair of magnetic blocks 21 separate from each other, and the concave part of the skirt 5 is accelerated to stretch to both sides, resulting in a setback effect, thereby increasing the opening force of the skirt 5 and further reducing the residue of the material on the surface of the skirt 5. With the separation of the pair of magnetic blocks 21, the billiard ball 23 can repeatedly hit the surface of the skirt 5 under the action of its own inertia and the elastic force of the elastic bar 22, causing the skirt 5 to vibrate and shake off the material on its surface, thereby further improving the separation efficiency between the material and the skirt 5 and preventing the material from adhering to the surface of the skirt 5.

[0050] When the skirt 5 is opened along its length, the elastic membrane 24 is stretched and deformed, and the outside air is sucked into the closed cavity between the elastic membrane 24 and the skirt 5 through the guide hole 26. When the concave part of the skirt 5 shrinks and resets to the middle, the spring piece 25 drives the elastic membrane 24 to recover and bend again, and then squeezes the air inside out through the guide hole 26, blowing the surface of the magnetic block 21, the elastic bar 22 and the billiard ball 23 to remove dust and other impurities on their surface, thereby ensuring their good working efficiency and preventing the problem of dust adhering to the surface of the magnetic block 21 affecting the suction effect, so that they can be smoothly sucked together again.
