Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a belt conveyor with adjustable conveying length. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as home appliances, food, coal mining, electronics, electrical appliances, and machinery. Existing belt conveyors generally have a fixed conveying distance, the end point cannot be changed, and the length of the conveyor belt cannot be dynamically adjusted. Changing the conveying distance requires replacing not only the conveyor belt but also the frame, significantly increasing operating costs. Furthermore, the inflexible end point limits the use of the conveyor belt. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a belt conveyor with adjustable conveying length, which can adjust the conveying length according to conveying requirements.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a belt conveyor with adjustable conveying length, comprising:

[0005] A frame is provided with multiple rollers, and a conveyor belt is fitted onto the rollers. The conveyor belt transports materials from the feed end to the discharge end of the conveyor.

[0006] The conveyor belt is sleeved on the telescopic mechanism, which is connected to the frame. The telescopic mechanism can move along the conveying direction of the conveyor belt to change the conveying length of the conveyor.

[0007] Furthermore, the telescopic mechanism includes a sliding plate that can move along the conveyor belt in the conveying direction;

[0008] It also includes a first roller and a second roller fixedly connected to the end of the slide plate. The first roller is disposed away from the feed end of the conveyor, and the second roller is disposed close to the feed end of the conveyor.

[0009] It also includes a third roller that is fixedly connected to the frame. The conveyor belt is sequentially mounted on the first roller, the second roller and the third roller, and the conveyor belt located between the first roller, the second roller and the third roller is in an "S" shape.

[0010] Furthermore, the third roller is located below the first roller and the second roller in the vertical direction; in the horizontal projection, the third roller is located between the first roller and the second roller.

[0011] Furthermore, the roller at the feed end and the first roller at the discharge end are at the same height in the vertical direction, and the lowest end of the second roller and the highest end of the third roller are at the same height in the vertical direction.

[0012] Furthermore, the telescopic mechanism also includes a slide rail and a slider. The slider is fixedly connected to the frame, and the slide rail is fixedly connected to the slide plate. It is set along the conveying direction of the conveyor and abuts against the slider. The slider can slide along the slide rail. By setting the slider and the slide rail, the slide rail slides along the preset direction of the slider, ensuring that the telescopic mechanism can slide along the conveying direction of the conveyor, thereby adjusting the conveying length of the conveyor.

[0013] Furthermore, multiple sliders are provided, each connected to a frame on both sides of the conveyor's conveying direction. Two slide rails are provided, symmetrically arranged on both sides of the conveyor frame, and abut against the sliders. The conveying length of the conveyor is changed by moving the slide rails closer to or away from the feed end.

[0014] Furthermore, four sliders are provided, with two sliders on each side of the conveyor in the conveying direction. By providing two sliders on each side of the conveyor, the slide rail can be positioned more effectively.

[0015] Furthermore, it also includes a width limiting mechanism, which includes two limiting rods arranged parallel to each other above the conveyor belt. The distance between the two limiting rods is the conveying width of the conveyor.

[0016] Furthermore, the limiting rod is disposed above the frame and is fixedly connected to the frame via a connecting assembly. The connecting assembly includes a first connecting rod disposed on one side of the frame and connected to the frame, and a second connecting rod connected to the limiting rod. The second connecting rod and the second limiting rod are arranged perpendicularly and are fixedly connected by a cross clamp.

[0017] Furthermore, the width limiting mechanism is provided in two sets: one set is located near the feeding end and is fixedly connected to the frame; the other set is located near the discharging end and is fixedly connected to the telescopic mechanism.

[0018] The beneficial effects of this utility model are:

[0019] By incorporating a telescopic mechanism, with the conveyor belt fitted onto it, the telescopic mechanism can alter the conveying length of the conveyor belt as it moves along the conveying direction, flexibly changing the conveying endpoint and expanding the conveyor's applicability. Through the arrangement of the first, second, and third rollers, the change in distance between the first roller and the feed end is equal to the change in distance between the second and third rollers, ensuring the conveyor belt remains taut to complete the material conveying process.

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] See appendix Figure 1 and attached Figure 2 As shown, in this embodiment, an adjustable conveyor belt includes a frame 1 with multiple rollers 4 on it. The conveyor belt 3 is fitted onto the rollers 4, and the rollers 4 rotate under the drive of a motor 5, which can drive the conveyor belt 3 to rotate and transport materials from the feed end 11 to the discharge end 12 of the conveyor.

[0032] In some embodiments, see Appendix Figure 1-4 As shown, a telescopic mechanism 2 is provided on the frame 1. The telescopic mechanism 2 includes a slider 23 fixedly connected to the frame 1, and the slider 23 is disposed on the frame 1 on both sides of the conveyor in the conveying direction. The telescopic mechanism 2 also includes a slide rail 22, which is arranged along the conveying direction of the conveyor and abuts against the slider 23. During the movement of the slide rail 22 along the conveying direction of the conveyor, the slider 23 and the slide rail 22 move relative to each other, and the second slider 23 slides along the second slide rail 22. Through the arrangement of the slider 23 and the slide rail 22, the slide rail 22 slides along the preset direction of the slider 23, ensuring that the telescopic mechanism 2 can slide along the conveying direction of the conveyor, thereby adjusting the conveying length of the conveyor.

[0033] In some embodiments, multiple sliders 23 are provided and are respectively connected to the frame 1 on both sides of the conveyor conveying direction. Two slide rails 22 are provided and are symmetrically arranged on both sides of the conveyor frame 1, abutting against the sliders 23. The slide rails 22 move closer to or away from the feed end, thereby changing the conveying length of the conveyor.

[0034] In some embodiments, four sliders 23 are provided, with two sliders on each side of the conveyor in the conveying direction. By providing two sliders 23 on each side of the conveyor, the slide rail 22 can be positioned more effectively.

[0035] In some embodiments, the telescopic mechanism 2 further includes a slide plate 21, which is fixedly connected to a slide rail 22. By driving the slide plate 21, the slide rail 22 is driven to slide along the slider 23 in the conveyor conveying direction. A handle 24 is provided on the side of the slide plate 21 away from the feed end of the conveyor, which facilitates the operator to drive the slide plate 21 to move towards or away from the feed end 11.

[0036] In some embodiments, rollers 4 are fixedly provided at both ends of the conveying direction of the slide plate 21. The first roller 41 is provided at the feed end 11 away from the conveyor, and the second roller 42 is provided at the feed end 11. A third roller 43 is also fixedly provided on the frame 1. The third roller 43 is located vertically below the first roller 41 and the second roller 42. In the horizontal projection, the third roller 43 is located between the first roller 41 and the second roller 42, or coincides with the horizontal projection of the second roller 42 / first roller 41. The conveyor belt 3 is sequentially sleeved on the first roller 41, the second roller 42 and the third roller 43. The conveyor belt 3 between the first roller 41, the second roller 42 and the third roller 43 is in an "S" shape.

[0037] During the extension and retraction of the telescopic mechanism 3, the conveyor belt 3 on the conveying surface above the frame 1 is the first conveyor belt 31, and its length is the conveying length of the conveyor. Assuming that to shorten the conveying length, the first roller 41 and the second roller 42 move synchronously towards the feed end 11, the length of the first conveyor belt 31 decreases by the distance the first roller 41 moves towards the feed end 11. The conveyor belt 3 between the first roller 41 and the second roller 42 is the second conveyor belt 32. Since the distance between the first roller 41 and the second roller 42 is fixed, the length of the second conveyor belt 32 remains unchanged. The conveyor belt 3 between the second roller 42 and the third roller 43 is the third conveyor belt 33. Since the second roller 42 moves towards the feed end 11 while the third roller 43 remains stationary, the length of the third conveyor belt 33 increases by the distance the second roller 42 moves towards the feed end 11. Therefore, the decrease in the first conveyor belt 31 is equal to the increase in the third conveyor belt 33, and the conveyor belt 3 can always maintain a taut conveying state. By setting the telescopic mechanism 2, the conveying length can be adjusted according to the conveying requirements.

[0038] In some embodiments, the roller 4 at the feed end 11 of the conveyor and the first roller 41 are at the same vertical height, ensuring that the first conveyor belt 31 conveys in a horizontal direction, which is beneficial for material conveying. The lowest point of the second roller 42 and the highest point of the third roller 43 are at the same vertical height, ensuring that the third conveyor belt 33 conveys in a horizontal direction. By ensuring that both the first conveyor belt 31 and the third conveyor belt 33 are horizontally arranged, it is ensured that during the extension and retraction of the telescopic mechanism, the horizontal distance increased or decreased by the first conveyor belt 31 and the third conveyor belt 33 is equal, and the conveyor belt 3 can always maintain a taut conveying state.

[0039] In some embodiments, the lowest end of the first roller 41 and the highest end of the second roller 42 are at the same height in the vertical direction, ensuring that the second conveyor belt 32 conveys in the horizontal direction.

[0040] See appendix Figure 5and attached Figure 6 As shown, in some embodiments, a width-limiting mechanism 6 is also included to limit the transport width of the conveyor. The width-limiting mechanism 6 includes a limiting rod 61, which is fixedly connected to the frame 1. Specifically, the limiting rod 61 is disposed above the frame 1 and fixedly connected to the frame 1 via a connecting assembly 62. The limiting rod 61 is disposed along the conveying direction of the conveyor belt 3 and is parallel to the conveying direction of the conveyor belt 3. Two limiting rods 61 are provided, which are disposed parallel to each other above the conveyor belt 3, and the distance between the two limiting rods 61 is the transport width of the conveyor.

[0041] In some embodiments, the connecting assembly 62 includes a first connecting rod 621 disposed on one side of the frame 1 and connected to the frame 1, and a second connecting rod 622 connected to the limiting rod 61. The second connecting rod 622 and the second limiting rod 61 are arranged vertically and connected by a cross clamp 623.

[0042] By changing the connection position of the cross clamp 623 and the second connecting rod 622, the length of the second connecting rod 622 extending towards the conveyor can be adjusted, thereby changing the distance between the two parallel limit rods 61 and adjusting the width of the conveyor.

[0043] By changing the connection position between the cross clamp 623 and the first connecting rod 621, the vertical height of the first connecting rod 621 can be adjusted, thereby changing its vertical height. This allows for adaptive adjustment of the height of the width-limiting mechanism 6 based on the height of the transported material.

[0044] In some embodiments, the width limiting mechanism 6 is provided in two sets. One set is located near the feed end and is fixedly connected to the frame 1, while the other set is fixedly connected to the telescopic mechanism 2 to limit the conveying width above the telescopic mechanism 2.
