Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more specifically to a belt conveyor anti-drifting assembly. Background Technology

[0002] When belt conveyors are in use, belt slippage is prone to occur in the concave-slope section, that is, the belt hangs in the air and breaks off from the support of the idler group. This has a great impact on the normal transportation of materials and may even cause the belt to break or completely break off from the idler group, posing a great threat to the production and transportation environment.

[0003] The current common solution is to install pressure rollers at the edge of the belt to press the edge of the belt against the idler roller assembly to prevent it from detaching from the idler roller assembly. During the up-and-down movement of the belt, the fixed pressure rollers will apply shear force to the belt, which can easily cause the belt to tear at the contact edge with the pressure rollers, affecting the service life of the belt. Moreover, when the belt completely detaches from the idler roller assembly and pressure rollers, it is still necessary to manually pull the cable switch to stop the machine, which makes it difficult to stop the machine in a timely manner.

[0004] Therefore, this application proposes an anti-drift belt assembly for belt conveyors to solve the above-mentioned technical problems. Summary of the Invention

[0005] The main objective of this invention is to address the aforementioned shortcomings by providing a belt conveyor anti-slipping component that can prevent slipping while reducing damage to the belt, and can also trigger a stop when the slipping completely detaches from the idler roller assembly.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A belt conveyor anti-slip assembly includes: multiple support frames symmetrically arranged on the top of a support frame and located on both sides of the belt; a mounting plate fixedly mounted on the support frames; an elastically telescopic upper pressing assembly slidably inserted into the top of the mounting plate and located on the upper surface of the belt; an elastically telescopic lower pressing assembly fixedly mounted on the bottom of the mounting plate and located on the lower surface of the belt; an adjusting member disposed on the upper pressing assembly for adjusting the distance between the upper and lower pressing assemblies; and a connecting member disposed on the upper and lower pressing assemblies and electrically connected to a pull-cord switch.

[0008] Furthermore, the upper pressure assembly includes an upper pressure plate slidably inserted into the top of the mounting plate, a first elastic telescopic rod fixedly disposed on the upper pressure plate, and a first pressure roller group fixedly disposed at the telescopic end of the first elastic telescopic rod.

[0009] Furthermore, the first pressure roller assembly includes a mounting base fixedly connected to the telescopic end of the first elastic telescopic rod, multiple parallel and rotatably arranged extrusion rollers on the mounting base, and a scraper fixedly arranged on the mounting base and located between two adjacent extrusion rollers.

[0010] Furthermore, the pressing assembly includes a pressing plate fixedly disposed at the bottom of the mounting plate, a second elastic telescopic rod fixedly disposed on the pressing plate, and a second pressure roller assembly fixedly disposed at the telescopic end of the second elastic telescopic rod.

[0011] Furthermore, the adjusting component includes a screw with one end rotatably mounted on the lower pressure plate and the other end passing through the upper pressure plate, a handle fixedly mounted on the end of the screw passing through the upper pressure plate, and an internally threaded sleeve fixedly mounted on the upper pressure plate and threadedly connected to the screw.

[0012] Furthermore, the connecting element includes a third elastic telescopic rod fixedly mounted on the upper pressure plate, a voltage-conducting roller fixedly mounted on the telescopic end of the third elastic telescopic rod and located on the upper surface of the belt, and a conductive block fixedly mounted on the lower pressure plate and located on the lower surface of the belt.

[0013] Furthermore, the voltage-conducting roller is connected to one of the normally open contacts of the pull-cord switch, and the conductive block is connected to the other normally open contact of the pull-cord switch.

[0014] Furthermore, it also includes a limiting strip fixedly disposed on the lower surface of the belt and parallel to the belt. The limiting strip has dovetail grooves symmetrically opened on both sides, and a conical wheel is disposed in the dovetail groove. The conical wheel is fixedly disposed on the bracket by a mounting bracket.

[0015] Furthermore, the idler roller assembly has a clearance groove on the support roller at the bottom of the belt that cooperates with the limiting strip.

[0016] The beneficial effects of this invention are reflected in:

[0017] 1. This invention uses elastically extendable upper and lower pressure components to clamp the belt between them, ensuring anti-drift effect while allowing the belt to swing up and down slightly, reducing the shear force applied to the belt and thus extending the belt's service life; the distance between the upper and lower pressure components can be adjusted by setting an adjusting component, making the upper and lower pressure components easier to install.

[0018] 2. The present invention provides a connecting element electrically connected to the pull-cord switch. When the belt is pulled away from the upper and lower pressure components due to the action of the belt, the connecting element connects the two normally open contacts of the pull-cord switch, thereby stopping the conveyor and eliminating the need for manual operation of the pull-cord switch.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1-11 As shown, the present invention provides a belt conveyor anti-drift belt assembly, comprising:

[0034] Multiple support frames 1 are symmetrically arranged on top of the bracket 2 and on both sides of the belt 3;

[0035] Mounting plate 4 is fixedly mounted on support frame 1;

[0036] The elastically telescopic upper pressure component 5 is slidably inserted into the top of the mounting plate 4 and located on the upper surface of the belt 3;

[0037] The elastically telescopic pressing component 6 is fixedly installed at the bottom of the mounting plate 4 and located on the lower surface of the belt 3;

[0038] Adjusting component 7 is provided on the upper pressing component 5 and is used to adjust the distance between the upper pressing component 5 and the lower pressing component 6;

[0039] The connecting element 8 is disposed on the upper pressure component 5 and the lower pressure component 6, and is electrically connected to the pull-cord switch 9.

[0040] In use, the mounting plate 4 is fixed on the bracket 2 by the support frame 1. Then, the distance between the upper pressing component 5 and the lower pressing component 6 is adjusted by the adjusting component 7 to increase the distance, so that the upper pressing component 5 can be placed on the upper surface of the belt 3 and the lower pressing component 6 can be placed on the lower surface of the belt 3. Then, the distance between the upper pressing component 5 and the lower pressing component 6 is reduced by the adjusting component 7, so that the elastic contraction component in the upper pressing component 5 and the lower pressing component 6 squeezes the belt 3 and contracts. While pressing the belt 3, it also allows the belt 3 to swing up and down to a certain extent, thereby reducing the damage to the belt 3 when the belt is flowing. When the belt 3 is pulled away from the upper pressing component 5 and the lower pressing component 6 due to the effect of the belt flowing, the connecting component 8 connects the pull switch 9 to stop the conveyor and avoid further damage to the conveyor frame.

[0041] In one embodiment, the upper pressure assembly 5 includes an upper pressure plate 51 slidably inserted into the top of the mounting plate 4, a first elastic telescopic rod 52 fixedly disposed on the upper pressure plate 51, and a first pressure roller group 53 fixedly disposed at the telescopic end of the first elastic telescopic rod 52. This design allows the first pressure roller group 53 to press against the upper surface of the belt 3. When the belt 3 floats upwards due to the belt's movement, the first elastic telescopic rod 52 contracts when the belt 3 applies pressure to the first pressure roller group 53, thereby allowing the belt 3 to float upwards a certain distance.

[0042] In one embodiment, the first pressure roller group 53 includes a mounting base 531 fixedly connected to the telescopic end of the first elastic telescopic rod 52, multiple parallel and rotatably mounted pressure rollers 532 on the mounting base 531, and a scraper 533 fixedly mounted on the mounting base 531 and located between adjacent pressure rollers 532. This design allows the first elastic telescopic rod 52 to be fixedly connected to the mounting base 531 to position the pressure rollers 532, while the scraper 533 can remove foreign matter adhering to the pressure rollers 532.

[0043] In one embodiment, the pressing assembly 6 includes a pressing plate 61 fixedly disposed at the bottom of the mounting plate 4, a second elastic telescopic rod 62 fixedly disposed on the pressing plate 61, and a second pressure roller group 63 fixedly disposed at the telescopic end of the second elastic telescopic rod 62. The second elastic telescopic rod 62 has the same structure as the first elastic telescopic rod 52, and the second pressure roller group 63 has the same structure as the first pressure roller group 53. When the belt 3 swings upward due to the action of the belt, the second elastic telescopic rod 62 extends to ensure that the second pressure roller group 63 always presses against the lower surface of the belt 3, allowing the belt 3 to swing while cooperating with the first pressure roller group 53 to keep the belt 3 pressed tightly during the swinging process, preventing the belt 3 from being pulled away from the first pressure roller group 53 and the second pressure roller group 63 during the swinging process. Due to the buffering effect of the first elastic telescopic rod 52 and the second elastic telescopic rod 62, the shear force applied to the belt 3 by the first pressure roller group 53 and the second pressure roller group 63 when the belt 3 swings up and down can be reduced, thereby extending the service life of the belt 3.

[0044] In one embodiment, the adjusting member 7 includes a screw 71 with one end rotatably mounted on the lower pressure plate 61 and the other end passing through the upper pressure plate 51, a handle 72 fixedly mounted on the end of the screw 71 passing through the upper pressure plate 51, and an internally threaded sleeve 73 fixedly mounted on the upper pressure plate 51 and threadedly connected to the screw 71. This design allows rotating the screw 71 to move the internally threaded sleeve 73 along the screw 71, and the internally threaded sleeve 73 to slide the upper pressure plate 51 along the mounting plate 4, thereby adjusting the distance between the upper pressure plate 51 and the lower pressure plate 61, and consequently, adjusting the distance between the upper pressure assembly 5 and the lower pressure assembly 6. The handle 72 makes it easier for the user to rotate the screw 71.

[0045] In one embodiment, the switching element 8 includes a third elastic telescopic rod 81 fixedly mounted on the upper pressure plate 51, a voltage-conducting roller 82 fixedly mounted on the telescopic end of the third elastic telescopic rod 81 and located on the upper surface of the belt 3, and a conductive block 83 fixedly mounted on the lower pressure plate 61 and located on the lower surface of the belt 3. This design allows the third elastic telescopic rod 81 to extend when the belt 3 is pulled away from the upper pressure assembly 5 and the lower pressure assembly 6 due to the belt's movement, causing the voltage-conducting roller 82 to contact the conductive block 83, thereby activating the pull-wire switch 9 and stopping the conveyor.

[0046] In one embodiment, the voltage-conducting roller 82 is connected to one normally open contact of the pull-coil switch 9, and the conductive block 83 is connected to the other normally open contact of the pull-coil switch 9. With this design, when the conveyor is running normally, the pull-coil switch 9 is in the normally closed state. When the belt 3 is pulled away from the upper pressure assembly 5 and the lower pressure assembly 6 due to the belt's movement, the voltage-conducting roller 82 and the conductive block 83 come into contact, thereby connecting the two normally open contacts of the pull-coil switch 9 and triggering the conveyor to stop.

[0047] In one embodiment, a limiting strip 10 is also included, which is fixedly disposed on the lower surface of the belt 3 and parallel to the belt 3. The limiting strip 10 has dovetail grooves symmetrically formed on both sides, and a conical wheel 11 is disposed within each dovetail groove. The conical wheel 11 is fixedly disposed on the bracket 2 via a mounting bracket 12. This design allows the conical wheel 11 to limit the limiting strip 10 through the dovetail grooves, making it difficult for it to swing up and down, thereby limiting the belt 3 and reducing the amplitude of its up-and-down swing when it is flowing. It also helps to prevent the belt 3 from deviating to a certain extent.

[0048] In one embodiment, the idler roller group 13 has a relief groove 15 on the support roller 14 at the bottom of the belt 3, which cooperates with the limiting strip 10. With this design, when the belt 3 is running, the limiting strip 10 is locked in the relief groove 15, ensuring the flatness of the upper surface of the belt 3. At the same time, the limiting effect of the relief groove 15 on both sides of the limiting strip 10 can also prevent the belt 3 from deviating to a certain extent.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0051] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, "multiple" refers to two or more. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
