[0001] The present disclosure relates generally to the field of automation equipment. More particularly, the present disclosure relates to an adjustable supporting device, a belt conveyor and an automated production system. BACKGROUND

[0002] In a production system for continuously and automatically processing materials, such as an automated ore dressing plant, a belt conveyor or other material conveying device needs to be arranged between different processes. In actual use, the height and / or distance between the belt conveyor and the feeding and discharging devices need to be adjusted to adapt to different device layouts. A conventional adjustment method is to provide a two-section telescopic supporting leg connected to the belt conveyor, and to provide a plurality of adjustment holes at equal intervals on one section of the two-section telescopic supporting leg. However, the length adjustment range of the two-section telescopic supporting leg can only be selected from an integer multiple of the distance between two adjacent adjustment holes, which may not match the required adjustment distance, resulting in unstable or impossible fixation of the belt conveyor and other conveying devices, gaps between the conveying device and the upstream and downstream devices, material leakage or jamming, and other situations that prevent normal material transportation.

[0003] Therefore, there is an urgent need to provide an adjustable supporting device, a belt conveyor and an automated production system to improve the adjustment accuracy of the horizontal distance of the conveying device. SUMMARY

[0025] The technical solutions in the embodiments of the disclosure will be apparently and completely described below with reference to the drawings in the embodiments of the disclosure. Obviously, the described embodiments are part of, rather than all of, the embodiments of the disclosure. Based on the embodiments in the disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the disclosure.

[0026] It should be understood that the terms “comprise” and “include” used in the specification and claims of the disclosure indicate the presence of described features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0027] It should also be understood that the terms used in the specification of the disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the disclosure. As used in the specification and claims of the disclosure, the singular forms “a,” “an,” and “the” are intended to include the plural forms, unless the context clearly indicates otherwise. It should be further understood that the term “and / or” used in the specification and claims of the disclosure means one or more of the associated listed items as well as all possible combinations of the items, and includes the items.

[0028] As used in the specification and claims, the term “if’ can be interpreted as meaning “when,” or “upon,” or “in response to a determination,” or “in response to a detection” depending on the context. Similarly, the phrase “if it is determined” or “if [the recited condition or event] is detected” can be interpreted as meaning “upon determining” or “in response to a determining” or “upon detecting [the recited condition or event]” or “in response to a detection of [the recited condition or event],” depending on the context.

[0029] In a production system that continuously and automatically processes materials, such as an automated ore dressing device, a material conveying mechanism, such as a belt conveyor, needs to be arranged between different processes. Due to production site limitations or production line arrangement limitations, the distance between the feeding device and the receiving device connected by the two ends of the conveying mechanism cannot be determined, and the height difference between the discharge port of the feeding device and the feeding port of the receiving device exists. To this end, the height and / or distance between the belt conveyor and the feeding device and the receiving device need to be adjusted to adapt to different device layouts.

[0030] Reference is made to Figure 1 , Figure 1 An exemplary perspective view of an existing belt conveyor is shown. The belt conveyor includes a belt 91 for transporting materials, a first connecting member 93 for connecting a feeding device, a second connecting member 92 for connecting a receiving device, and a two-section telescopic support leg 94 connected to the belt conveyor. A plurality of adjustment holes spaced at equal distances are arranged on one section of the two-section telescopic support leg 94, and one or two fixed holes are arranged on the other section. The length of the telescopic support leg 94 is adjusted by aligning and fixing different adjustment holes with fixed holes to adjust the height and horizontal length of the belt conveyor. However, the adjustment distance of this adjustment method can only be adjusted by the distance between two adjacent adjustment holes as the minimum adjustment unit. The actual distance between the upstream and downstream devices of the conveying device may fall between the adjustable distances of two adjacent adjustment holes, resulting in unstable or impossible fixation of the conveying device, such as the belt conveyor. At this time, a gap may be generated between the conveying device and the upstream and downstream devices, causing material leakage or material jamming, and the materials cannot be normally transported.

[0031] Therefore, the present disclosure provides an adjustable support device, a belt conveyor, and an automated production system. The adjustable support device includes a first adjustment member and a second adjustment member that are sleeved. The first adjustment member is provided with a plurality of first inner holes and second inner holes that are sequentially spaced at a first interval, and the second adjustment member is provided with a plurality of first outer holes and second outer holes that are spaced at a second interval. By setting the first interval to be different from the second interval, and aligning at least one second inner hole with one second outer hole when one first inner hole is aligned with one first outer hole, the adjustment precision of the support device can be simply improved.

[0032] The detailed description of the specific embodiments of the present disclosure will be made in conjunction with the accompanying drawings.

[0033] Referring to Figures 2 to 4 , Figure 2 An exemplary front view of an adjustable support device of some embodiments of the present disclosure is shown, Figure 3 An exemplary front view of a first adjustment member of an adjustable support device of some embodiments of the present disclosure is shown, Figure 4 An exemplary front view of a second adjustment member of an adjustable support device of some embodiments of the present disclosure is shown.

[0034] As Figures 2 to 4 shown, in this embodiment, the adjustable support device 100 comprises a first adjustment member 10 and a second adjustment member 20 which are nested with each other. The first adjustment member 10 is provided with a plurality of first inner holes 11 which are arranged in a first interval a1, and a plurality of second inner holes 12 which are also arranged in the first interval a1. The second adjustment member 20 is nested outside the first adjustment member 10, and is provided with a plurality of first outer holes 21 which are arranged in a second interval a2, and a plurality of second outer holes 22 which are also arranged in the second interval a2. The first interval a1 is not equal to the second interval a2, and the first inner holes 11 and the first outer holes 21 can be aligned and connected with each other by means of a fixing pin 31. When one first inner hole 11 and one first outer hole 21 are aligned, at least one second inner hole 12 and at least one second outer hole 22 are aligned and can be connected with each other by means of a fixing pin 31.

[0035] Specifically, in this embodiment, the first adjustment member 10 can be formed in a strip shape, and is provided with a plurality of first inner holes 11 which are arranged in the first interval a1 along the length direction thereof, and a plurality of second inner holes 12 which are also arranged in the first interval a1 along the length direction thereof. The number of the first inner holes 11 is equal to the number of the second inner holes 12. The first adjustment member 10 further comprises a first segment 110 and a second segment 120 which are arranged in a direction interval, and the plurality of first inner holes 11 are arranged in the first segment 110, while the plurality of second inner holes 12 are arranged in the second segment 120. The second adjustment member 20 is formed in a hollow or partially hollow strip shape, and the hollow inner cavity is used for nesting the first adjustment member 10. The second adjustment member 20 is provided with a plurality of first outer holes 21 which are arranged in the second interval a2 along the length direction thereof, and a plurality of second outer holes 22 which are also arranged in the second interval a2 along the length direction thereof. Similar to the first adjustment member 10, the second adjustment member 20 further comprises a third segment 210 and a fourth segment 220 which are arranged in a direction interval, and the plurality of first outer holes 21 are arranged in the third segment 210, while the plurality of second outer holes 22 are arranged in the fourth segment 220.

[0036] wherein, in this embodiment, the closest first inner hole 11 and second inner hole 12 have a first inner distance c1, the closest first outer hole 21 and second outer hole 22 have a second inner distance c2, the first inner holes 11 arranged in the first section 110 have a first outer distance b1 between the first inner holes 11 at the ends, and the first outer holes 21 arranged in the third section 210 have a first outer distance b2 between the first outer holes 21 at the ends. In order to have at least one second inner hole 12 corresponding to one second outer hole 22 when each first inner hole 11 corresponds to a first outer hole 21, the first distance a1 and the second distance a2 can be an integer multiple of the length difference between the first distance a1 and the second distance a2, the first inner distance c1 and the second inner distance c2 are equal, and the product of the total number of intervals between a plurality of adjacent first inner holes 11 or a plurality of adjacent second inner holes 12 and the length difference is equal to the length of the second interval. Thus, when the first inner distance c1 and the second inner distance c2 are equal, the product of the total number of intervals between a plurality of adjacent second outer holes 22 and the second distance a2 is equal to the product of the total number of intervals between a plurality of adjacent first outer holes 21 and the first distance a1.

[0037] When a first inner hole 11 and a first outer hole 21 are aligned, the distance between at least one second inner hole 12 and the first inner hole 11 is the sum of the first inner distance c1 and the first outer distance b1. Based on the above arrangement, the value of the sum is equal to the sum of c2 and b2, i.e. there is a second outer hole 22 aligned with at least one second inner hole 12 at a distance of the value of the sum from the second outer hole 22 corresponding to the first inner hole 11.

[0038] For example, see Figure 5 , Figure 5An exemplary exploded view of an adjustable support device according to some embodiments of this disclosure is shown, wherein a first inner hole 11 and a first outer hole 21 are aligned. In this embodiment, the first inner distance c1 on the first adjusting member 10 is 220 mm, and the second inner distance c2 on the second adjusting member 20 is also 220 mm. The value of the first spacing a1 is 45 mm, the value of the second spacing a2 is 50 mm, and the length difference between the first spacing a1 and the second spacing a2 is 5 mm. Therefore, the number of first inner holes 11 and second inner holes 12 can both be arranged to be 11, and the number of first outer holes 21 and second outer holes 22 can both be arranged to be 10. This results in a total number n1 of interval segments between multiple adjacent first inner holes 11 being 10, and a total number n2 of interval segments between multiple adjacent first outer holes 21 being 9. At this point, the first outer distance b1 in the first segment 110 is the product of the first spacing a1 and the number n1 of the intervals between multiple adjacent first inner holes 11, i.e., b1 = a1 × n1 = 45 mm × 10 = 450 mm. The second outer distance b2 in the second segment 120 is the product of the second spacing a2 and the number n2 of the intervals between multiple adjacent first outer holes 21, i.e., b2 = a2 × n2 = 50 mm × 9 = 450 mm.

[0039] like Figure 5 As shown, when aligning the first inner hole 11 of the first adjusting member 10 on the side opposite to the second segment 120 with the second outer hole 21 of the second adjusting member 20 on the side opposite to the fourth segment 220, there are a total of n1 interval segments between the first inner hole 11 and at least one corresponding second inner hole 12. At this time, the corresponding second inner hole 12 is the first second inner hole 12 on the second segment 120 closest to the first segment 110. Based on this, for the second adjusting member, there are a total of n2 interval segments between the second outer hole 21 and at least one corresponding second outer hole 22. The corresponding second outer hole 22 is the second second outer hole 22 on the fourth segment 220 closest to the third segment 210. The distance between the first second inner hole 12 and the first inner hole 11 is n1×a1+c1=45 mm×10+220 mm=670 mm. The distance between the second outer hole 22 and the second outer hole 21 is n2×a2+c2=50 mm×9+220 mm=670 mm. That is, at this time, the second outer hole 22 on the fourth segment 220 is aligned with the first inner hole 12, so that the first adjusting member 10 and the second adjusting member 20 can be fixed by two pairs of corresponding holes by means of pins or bolts.

[0040] Further, see Figure 6 , Figure 6An exemplary exploded view of the adjustable support device of some embodiments of the present disclosure is shown, in which a first inner hole 11 is aligned with a second inner hole 12. In the embodiment shown in Figure 6 In the embodiment shown in Figure 5 In the embodiment shown in

[0041] In the embodiment shown in Figure 5 In the embodiment shown in Figure 5 In the embodiment shown in Figure 5 In the embodiment shown in Figure 6 In the embodiment shown in

[0042] It will be appreciated by those skilled in the art that although the above describes a scheme in which the first spacing a1 is limited to 45 mm and the second spacing a2 is limited to 50 mm to achieve distance adjustment in units of 5 mm, the values can be changed as needed to achieve a more suitable adjustment precision. For example, if higher assembly precision is required, the difference between the first spacing a1 and the second spacing a2 can be 1 mm or other smaller values.

[0043] In addition, referring to Figure 3 and Figure 7 , Figure 7An exemplary sectional view of the adjustable support device of some embodiments of the present disclosure is shown. In this embodiment, the first adjusting member 10 and the second adjusting member 20 are both provided as hollow square tubes, and the first inner hole 11, the second inner hole 12, the first outer hole 21, and the second outer hole 22 are all through holes that pass through the first adjusting member 10 or the second adjusting member 20. Thus, after the length is adjusted by the first adjusting member 10 and the second adjusting member 20, the first adjusting member 10 and the second adjusting member 20 can be fixed by the fixing pin 31 that passes through the first inner hole 11 and the first outer hole 21, and the second inner hole 12 and the second outer hole 22 of the first adjusting member 10 and the second adjusting member 20 that are aligned. Further or alternatively, the fixing pin 31 can pass through the first adjusting member 10 and the second adjusting member 20 that are coupled, and protrude from the other side of the second adjusting member 20, and be fixed by the locking pin 32 that passes through the protruding part in a direction perpendicular to the axis of the fixing pin 31.

[0044] Those skilled in the art can understand that, although the above describes a scheme in which the first inner hole 11, the second inner hole 12, the first outer hole 21, and the second outer hole 22 are provided as through holes in the first adjusting member 10 and the second adjusting member 20 that are formed as hollow square tubes, the present disclosure is not limited in the specific formation of the first adjusting member 10 and the second adjusting member 20. For example, in some embodiments not shown, the first adjusting member 10 and the second adjusting member 20 are both formed as tubes with circular cross sections. Further or alternatively, the first outer hole 21 and the second outer hole 22 are long holes that extend in the spacing direction, so that installation is more convenient. For another example, in some embodiments, the first inner hole 11 and the second inner hole 12 are provided as threaded holes, so that the first adjusting member 10 and the second adjusting member 20 can be directly fixed by bolts. In this case, the above inner holes and outer holes do not need to be formed as through holes, so that the processing cost is reduced, and installation and maintenance are more convenient.

[0045] Further, in some embodiments, the first inner holes 11 and the second inner holes 12 are arranged in an interleaved manner, i.e., a part of the second inner holes 12 are arranged in the spacing sections between the adjacent first inner holes 11. Similarly, the first outer holes 21 and the second outer holes 22 are also arranged in an interleaved manner. Thus, in the case where the space for arranging the adjustable support device 100 is small, higher adjustment accuracy can be achieved. In addition, in other embodiments, the axial directions of the first inner holes 11 and the first outer holes 21 are perpendicular to the axial directions of the second inner holes 12 and the second outer holes 22, so that the first inner holes 11 and the first outer holes 21 and the corresponding fixing members of the second inner holes 12 and the second outer holes 22 can respectively fix the first adjusting member 10 and the second adjusting member 20 in two directions perpendicular to each other, so that the probability of loosening of the first adjusting member 10 and the second adjusting member 20 around the fixing member due to one-way fixing is reduced.

[0046] Further, in some embodiments, the first adjusting member 10 further comprises a plurality of third inner holes arranged in sequence at a first interval a1, and the second adjusting member 20 comprises a plurality of third outer holes arranged in sequence at a second interval a2. The plurality of third inner holes are arranged on the first adjusting member 10 at a side close to the first segment 110 and away from the first segment 110, and similarly, the plurality of third outer holes are arranged at a side close to the fourth segment 220 and away from the third segment 210. Thus, after the first inner hole 11 and the first outer hole 21 are aligned and fixed, the second inner hole 12 and the second outer hole 22, and the third inner hole and the third outer hole can be fixed in opposition, so as to increase the connection fixed positions and improve the overall structural strength of the support device, especially when the overall length of the support device is relatively long, the risk of connection failure or deformation can be reduced.

[0047] Referring to Figure 8 , Figure 8 An exemplary front view of an automated production system according to some embodiments of the present disclosure is shown. In this embodiment, the automated production system 300 comprises a belt conveyor 200, a feeding device 70, and a collecting device 80, wherein the belt conveyor 200 comprises an adjustable support device 100 according to embodiments of the present disclosure. The belt conveyor 200 has a belt conveyor body, one end of which is connected to the discharge port of the feeding device, and the other end is connected to the inlet of the collecting device. One of the first adjusting member and the second adjusting member of the adjustable support device 100 is fixedly connected to the belt conveyor body, and the other is fixedly connected to the collecting device 80. Thus, the distance between the discharge port of the belt conveyor 200 and the collecting device 80 can be adjusted by means of the adjustable support device 100, and the generation of gaps can be prevented by high-precision adjustment.

[0048] While the embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that many changes, modifications and alternatives can be made thereto without departing from the spirit and scope of the present disclosure. It should be understood that various alternatives to the embodiments of the present disclosure described herein can be employed in practicing the present disclosure. The appended claims are intended to cover all such alternatives and equivalents.
