Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a double-layer speed-multiplying link platform. Background Technology

[0002] In automated production processes, connecting platforms are needed to link various devices and form a complete automated production line. Generally, the movement of products on the connecting platform is achieved through a sprocket structure or a timing belt structure. At this time, the product is placed directly on the upper side of the chain or timing belt. As the chain or timing belt rotates, the product moves synchronously. However, this is only suitable for lighter products. For heavier products, placing them on the upper side of the chain or timing belt will deform the chain or timing belt, thus affecting the normal flow of the product and consequently affecting the entire automated process.

[0029] 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.

[0030] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 7 As shown, a double-layer speed-multiplying link platform is characterized by comprising a bottom support 1 and an upper support 2 arranged in two layers, the bottom support 1 and the upper support 2 being spaced apart by vertical supports. Each of the bottom support 1 and the upper support 2 includes two parallel side supports 3. The top side of each side support 3 has an upper groove 31, and rolling platforms 311 are provided on both sides of the upper groove 31. Rotating sprockets 4 are provided at both ends of each side support 3, and a conveyor chain 5 is provided between the two sprockets 4. The conveyor chain 5 includes several rolling shafts 51, with a protrusion 511 in the middle of each rolling shaft 51. Rolling portions 512 that abut against the rolling platforms 311 are provided on both sides of the protrusion 511. When the rolling portions 512 of the conveyor chain 5 roll on the rolling platforms 311, the lower side of the protrusion 511 is located within the upper groove 31, and the upper side of the protrusion 511 protrudes from the upper side of the side support 3 and contacts the conveyed product.

[0033] At this time, the sprocket 4 includes multiple rolling shafts 51. The rolling shafts 51 are rolledly connected to the side bracket 3 through rolling parts 512. The rolling shafts 51 and the side bracket 3 are rolledly connected, which allows them to withstand a large weight. At this time, the sprocket 4 as a whole will not deform. The product contacts the protrusion 511 of the rolling shaft 51. When the sprocket 4 rotates as a whole, the product can move together with the rolling shaft 51, thereby ensuring the normal transmission process of the product.

[0034] In order to connect all the rolling shafts 51 into a single chain structure, in this embodiment, the sprocket 4 further includes a connecting piece 513 disposed on the outside of the rolling shafts 51. The height of the connecting piece 513 is less than the diameter of the rolling part 512. To prevent the connecting piece 513 from affecting the normal rolling of the rolling shafts 51, the height of the connecting piece 513 is less than the diameter of the rolling part 512, meaning the connecting piece 513 will not contact the side support 3. This allows the rolling shafts 51 to rotate normally when rolling at the side support 3 position.

[0035] In this embodiment, for the chain structure as a whole, the connecting piece 513 has fixing holes 514 at both ends, the rolling shaft 51 has a through rotating hole in the middle, the rotating hole has a rotating shaft 515 inside, the two ends of the rotating shaft 515 are fixed to the connecting piece 513 respectively, and the rolling shaft 51 is located between the two connecting pieces 513. At this point, the connecting piece 513 is divided into an inner connecting piece 513 and an outer connecting piece 513. First, the rolling shaft 51 passes through the rotating hole on the outside of the rotating shaft 515. Then, the ends of two adjacent rotating shafts 515 are fixed to the fixing holes 514 of the inner connecting piece 513. At this time, the two adjacent rolling shafts 51 are fixed together on both sides by the two inner connecting pieces 513 to form a chain structure. Then, the two chain structures are connected together by the outer connecting piece 513. At this time, the outer connecting piece 513 is located on the outside of the inner connecting piece 513. In this way, several rolling shafts 51 can be connected together to form a complete chain structure. At this time, the inner connecting piece 513, the outer connecting piece 513 and the rotating shaft 515 are riveted together, which allows relative rotation, so that the chain can rotate to a specific arc at the sprocket 4 position.

[0036] At this time, the product is placed on the upper side of the protrusion 511 of the rolling shaft 51. Specifically, the side support 3 also includes a first side wall 32 and a second side wall 33 on the outer side of the rolling platform 311. The tops of the first side wall 32 and the second side wall 33 extend toward the middle to form an upper side wall 34. A slot 35 is formed between the two upper side walls 34. The protrusion 511 of the rolling shaft 51 protrudes from the slot 35 to the upper side of the upper side wall 34. After setting the first sidewall 32 and the second sidewall 33, the sidewall of the sprocket 4 is surrounded. At the same time, an upper sidewall 34 is formed on the upper side of the first sidewall 32 and the second sidewall 33. The interior of the side bracket 3 is connected to the outside through the slot 35 of the upper sidewall 34. At this time, the width of the slot 35 is slightly larger than the width of the protrusion 511. This allows the conveyor chain 5 to be only partially exposed at the position of the side bracket 3, thereby ensuring the conveyor chain 5's function of conveying products. At this time, without affecting the conveying function of the conveyor chain 5, more of the part is surrounded inside the side bracket 3, which can prevent debris from the external environment from entering the structure of the conveyor chain 5, thereby reducing the interference of the external environment on the conveyor chain 5 and extending the service life of the conveyor chain 5.

[0037] Since the conveyor chain 5 is a ring structure, a support needs to be formed on the lower side of the conveyor chain 5. Therefore, in this embodiment, a lower platform 36 is provided between the first side wall 32 and the second side wall 33 of the side support 3. The lower platform 36 is provided with a lower groove 37 corresponding to the protrusion 511 of the rolling shaft 51. Rolling platforms 311 are also provided on both sides of the lower groove 37. An arc-shaped transition block 38 is provided between the sprocket 4 and the lower platform 36. The arc-shaped transition block 38 is provided with an arc-shaped lower groove 37 with the same width as the lower groove 37. The arc-shaped lower groove 37 is aligned with the lower groove 37. At this time, items are placed on the upper side of the conveyor chain 5 for product transfer. Items are not required on the lower side of the conveyor chain 5 (return position). However, for the stability of the lower side of the conveyor chain 5 during the return process, a lower groove 37 is also provided. At the same time, to enable the conveyor chain 5 to mesh better with the sprocket 4, arc-shaped transition blocks 38 are provided at both ends of the side bracket 3. The arc-shaped transition blocks are provided with arc-shaped lower grooves 37, making the conveyor chain 5 more stable during operation.

[0038] In order to drive the conveyor chain 5, in this embodiment, the sprocket 4 includes a main shaft 41. The outer side of the main shaft 41 is provided with a first rotating wheel 42 and a second rotating wheel 43 in parallel. The first rotating wheel 42 and the second rotating wheel are respectively provided with a groove 44 corresponding to the rolling part 512. The two driving parts on the same side are connected by a driven shaft 45. The outer side of the driven shaft 45 is provided with a driven sprocket 446. The driven sprocket 446 is connected to a drive motor 47 through a chain to control the rotation of the sprocket 4. After setting the first rotating wheel 42 and the second rotating wheel 43, when the conveyor chain 5 meshes with the sprocket 4, the first rotating wheel 42 and the second rotating wheel 43 respectively contact the rolling parts 512 on both sides of the protrusion 511, thereby increasing the contact area between the conveyor chain 5 and the sprocket 4. In this way, the sprocket 4 is not easily deformed during use, thereby ensuring the stability of the transmission process (especially for heavy products). At the same time, a corresponding drive motor 47 is set, and the drive sprocket 4 is set on the shaft of the drive motor 47. The drive sprocket 4 and the driven sprocket 446 are transmitted through a chain, thereby causing the driven shaft 45 to rotate, which in turn controls the rotation of the main shaft part 41 of the corresponding chain, thereby realizing the drive of the conveyor chain 5.

[0039] Since the side support 3 needs to bear a certain weight, the side support 3 has a certain thickness, so there is a certain gap between the end of the side support 3 and the sprocket 4. In order to ensure that the position between the end of the side support 3 and the sprocket 4 supports the transmission chain 5, in this embodiment, the end of the side support 3 is also provided with two side mounting plates 6. The side mounting plates 6 are fixed to both sides of the side support 3. The sprocket 4 is located between the two side mounting plates 6. A wheel receiving plate 7 is also provided between the sprocket 4 and the side support 3. The wheel receiving plate 7 is provided with an outer groove 71 corresponding to the upper groove 31. After setting the side mounting plate 6, not only can the two sides of the side bracket 3 be fixed, thereby increasing the stability of the side bracket 3, but also a receiving space can be formed at both ends of the side bracket 3. At this time, the sprocket 4 is placed in the receiving space, and a wheel receiving plate 7 is set between the sprocket 4 and the end of the side bracket 3. At this time, the height of the wheel receiving plate 7 is small, so it can be close to the sprocket 4. In this way, after the rolling shaft 51 of the conveyor chain 5 is separated from the sprocket 4, it can directly enter the outer groove 71 of the wheel receiving plate 7, thereby forming a support for the rolling shaft 51 and supporting the part of the conveyor chain 5 between the sprocket 4 and the side bracket 3, thus forming the full support of the conveyor chain 5 and improving the stability of the conveyor chain 5 in the process of conveying heavy objects.

[0040] Meanwhile, since the sprocket 4 is circular, there is a gap on its outer surface, preventing the product from rotating. In this embodiment, to avoid this, a transition wheel 8 is provided at the outer end of the side mounting plate 6. The two sides of the transition wheel 8 are rotatably connected to the side mounting plate 6 via transition shafts. The upper side of the transition wheel 8 is at the same height as the upper side of the protrusion 511 of the rolling shaft 51. The transition wheel 8 is positioned on the outer side of the side mounting plate 6. At this time, a groove is provided on the side mounting plate 6, and the transition wheel 8 is rotatably positioned in the groove, thereby forming a rolling support on the outer side of the side mounting plate 6 to provide better support for the product.

[0041] For the connecting platform, it may be necessary to lift the product when it moves to the middle position to complete other processes. Therefore, in this embodiment, the side support 3 is provided with a lifting structure 9 in the middle. The lifting structure 9 includes a lifting fixing plate 91 fixed to the lower side of the side support 3. The lifting fixing plate 91 is provided with a lifting cylinder 92 in the middle. The piston rod of the lifting cylinder 92 is connected to a lifting support plate 93. The lifting support plate 93 is located between the two side supports 3 at the same height. Furthermore, the lifting structure 9 is also provided with a blocking structure 10 on both sides. The blocking structure 10 includes a blocking base plate 101 fixed to the lower side of the side support 3. The blocking base plate 101 is provided with a fixed blocking cylinder 102. The blocking cylinder 102 is provided with a blocking part 103. The blocking cylinder 102 controls the blocking part 103 to move up and down, thereby blocking the product at the position of the conveyor chain 5 and preventing it from moving further. Then, the lifting cylinder 92 controls the lifting plate 93 to move upward, thereby lifting the product at the position of the conveyor chain 5 and separating it from the conveyor chain 5, so that the product can be processed in other processes. At this time, the blocking cylinder 102 can directly use the existing modules sold on the market, and the overall structure is simpler.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
