The timing belt assembly includes a drive wheel, a driven wheel, and a timing belt wound around the drive wheel and the driven wheel. The drive wheel and the driven wheel are respectively connected to the column, and the lifting frame is connected to the timing belt. The timing belt assembly can drive the lifting frame to rise and fall relative to the column.

[0004] However, after running for a long time, the smoothness of the lifting frame of the hopper elevator decreases. Utility Model Content

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] Currently, the bin elevator includes a column, a lifting frame, and a timing belt assembly. The lifting frame is vertically mounted on the column. The timing belt assembly includes a drive pulley, a driven pulley, and a timing belt wound around the drive and driven pulleys. The drive and driven pulleys are connected to the column, and the lifting frame is connected to the timing belt. The timing belt assembly drives the lifting frame to rise and fall relative to the column. However, after prolonged operation, the smoothness of the lifting frame's movement decreases. On one hand, the timing belt is located entirely on the outside of the column, resulting in a longer cantilever length for the lifting frame. This not only places high demands on the overall strength of the lifting frame but also causes the guide wheels on the lifting frame to bear a greater load. On the other hand, after prolonged operation, an angle may appear between the drive and driven pulleys, affecting the transmission efficiency and stability of the timing belt assembly.

[0051] To address the aforementioned problems, this application provides a bin elevator, including a base assembly, a column, a support, a timing belt assembly, a lifting frame, and two adjusting components. The timing belt assembly includes a driving pulley, a driven pulley, and a timing belt. The driving pulley is rotatably mounted on the base assembly, the driven pulley is rotatably connected to the support, and the timing belt passes through a cavity in the column. Compared to existing methods where the timing belt is entirely located outside the column, the timing belt in the bin elevator provided in this application can pass through the column. This built-in timing belt layout effectively shortens the overall length of the lifting frame, reduces the overall strength requirements of the lifting frame, and avoids the guide wheels of the lifting frame bearing greater loads. The two adjusting components are respectively connected between the two ends of the driven pulley's axle and the support. After prolonged operation, the parallelism between the axis of the driving pulley and the axis of the driven pulley can be adjusted using these two adjusting components, ensuring the transmission efficiency and stability of the timing belt assembly. Thus, the bin elevator can guarantee the smooth lifting and lowering of the lifting frame after long-term operation.

[0052] The specific structure of the hopper elevator provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 7 As shown in the figure, this application provides a bin lifting machine, including a base assembly 100, a column 200, a support 300, a timing belt assembly 400, a lifting frame 500, and two adjusting assemblies 600.

[0054] The base assembly 100 provides support and stability for the hopper elevator. A column 200 is mounted on the base assembly 100, and the column 200 has an internal cavity 211 extending axially along its axis. The axis of the column 200 extends vertically, and the cavity 211 extends from one end of the column 200 to the other. For example, the column 200 can be made of aluminum alloy, and its bottom end can be fastened to the base assembly 100 using fasteners.

[0055] The support 300 is mounted on the top of the column 200. Optionally, the support 300 can be fastened to the top of the column 200 with fasteners.

[0056] The timing belt assembly 400 includes a driving pulley 410, a driven pulley 420, and a timing belt 430 wound around the driving pulley 410 and the driven pulley 420. The driving pulley 410 is rotatably mounted on the base assembly 100, and the driven pulley 420 is rotatably connected to the support 300. The driven pulley 420 includes an axle 421 that passes through the support 300, and the timing belt 430 passes through the cavity 211.

[0057] Those skilled in the art will understand that the axis of the axle 421 is the same as the axis of the driven wheel 420. The driving wheel 410 is connected to the drive mechanism of the hopper elevator. When the drive mechanism drives the driving wheel 410 to rotate, the driving wheel 410 can drive the driven wheel 420 and the timing belt 430 to move. Figure 7 As shown, part of the synchronous belt 430 is located inside the cavity 211, and another part is located on the outside of the column 200. In this embodiment, the synchronous belt 430 can pass through the column. By using the layout of the built-in synchronous belt 430, the overall length of the lifting frame 500 is effectively shortened, the space occupation is optimized, and the overall strength requirements of the lifting frame 500 are reduced, avoiding the guide wheel of the lifting frame 500 from bearing a greater load.

[0058] The lifting frame 500 is vertically and flexibly mounted on the column 200 and connected to the synchronous belt 430. Specifically, the lifting frame 500 and the synchronous belt 430 are connected at the outer side of the column 200. When the driving component drives the synchronous belt 430 to move via the drive wheel 410, the synchronous belt 430 can drive the lifting frame 500 to move relative to the column 200 along the axial direction of the column 200, thereby achieving the lifting and lowering of the lifting frame 500. This embodiment does not limit the connection method between the lifting frame 500 and the synchronous belt 430; those skilled in the art can configure it as needed. In one possible implementation, the lifting frame 500 is provided with a guide wheel, which can roll on the column 200.

[0059] Two adjusting components 600 are respectively connected between the two ends of the axle 421 and the support 300. The two adjusting components 600 are configured to adjust the height of the two ends of the axle 421. Specifically, the height of the axle 421 and its connected end can be adjusted by adjusting the height of the two ends of the axle 421 by adjusting the two adjusting components 600 respectively, so that the axis of the driven pulley 420 is parallel to the axis of the driving pulley 410, thereby ensuring the transmission efficiency and stability of the synchronous belt assembly 400.

[0060] The bin lifting machine provided in this embodiment is suitable for handling bin-type goods, specifically for high-density bin automated warehousing scenarios. The bin lifting machine is suitable for scenarios with high production cycle and stability requirements, such as e-commerce smart warehousing, pharmaceutical warehouses, and intelligent manufacturing automated warehouses, and is particularly suitable for automated systems with high production efficiency and high-density bin storage. According to industry data, the domestic bin-type automated warehousing market has an annual growth rate of 20%. This technology, with its high space utilization rate and high safety features, can significantly reduce the number of maintenance operations due to warehousing accidents, while improving equipment operating efficiency, possessing technological leadership and market competitiveness.

[0061] In one embodiment, such as Figures 2-5As shown, the support 300 includes two spaced-apart support frames 310, with the wheel body 422 of the driven wheel 420 located between the two support frames 310. Each support frame 310 has a mounting cavity 311. Each support frame 310 can be locked to the top of the column 200 by fasteners.

[0062] The axle 421 includes an axle body 4211 and two connecting sections 4212 located at both ends of the axle body 4211. The two connecting sections 4212 are respectively inserted into the mounting cavities 311 of the two support frames 310. The two ends of the axle body 4211 abut against the two support frames respectively, and the adjusting assembly 600 is connected to the support frame 310 and the connecting sections 4212 respectively.

[0063] In this design, the driven wheel 420 has its wheel body 422 fitted onto the shaft 4211 and is rotatable relative to the shaft 4211. Both connecting sections 4212 of the axle 421 are located on the outer side of the wheel body 422. For example... Figure 5 As shown, the axle 421 has a stepped portion between the shaft body 4211 and the connecting section 4212. After the hopper elevator is assembled, the two stepped portions of the axle 421 abut against the opposite sides of the two support frames 310. The two support frames 310 can axially limit the axle 421, so that the driving wheel 410 can reliably drive the driven wheel 420 and the synchronous belt 430 when rotating.

[0064] When the connecting section 4212 of the axle 421 extends into the mounting cavity 311 of the corresponding support frame 310, the support frame 310 can restrict the movement of the connecting section 4212 in the front-back direction. The adjusting component 600 can be connected to the top and the connecting part of the support frame 310 respectively. By adjusting the adjusting component 600, the height of the connecting section 4212 connected to it in the corresponding mounting cavity 311 can be adjusted, thereby making the axis of the driven wheel 420 parallel to the axis of the driving wheel 410.

[0065] In a specific embodiment, such as Figures 2-5 As shown, the adjusting assembly 600 includes an adjusting member 610. The adjusting member 610 passes through the support frame 310 and is axially confined on the support frame 310. A threaded hole is provided on the connecting section 4212, and an external thread that mates with the threaded hole is provided on the adjusting member 610.

[0066] Bolts can be used as adjusting members 610. A through hole can be opened on the top of the support frame 310. The adjusting member 610 passes through the through hole and extends into the mounting cavity 311. After passing through the support frame 310, the adjusting member 610 can rotate relative to the support frame 310, but cannot move along its own axial direction relative to the support frame 310.

[0067] The threaded hole on the connecting section 4212 is coaxially arranged with the through hole on the support frame 310. The adjusting member 610 passes through the support frame 310 and extends into the threaded hole, where it is threadedly connected. When the adjusting member 610 is connected to the connecting section 4212, the mounting cavity 311 of the support frame 310 can limit the connection section 4212. When the operator rotates the adjusting member 610, the corresponding connecting section 4212 can move along the axial direction of the adjusting member 610, thereby adjusting the height of the corresponding connecting section 4212.

[0068] In one possible implementation, the cross-sectional shape of the connecting segment 4212 can be approximately square. When the connecting segment 4212 extends into the mounting cavity 311, the support frame 310 can restrict the rotation of the axle 421, facilitating the connection between the adjusting member 610 and the corresponding connecting segment 4212.

[0069] In other embodiments, a telescopic member can be used as an adjusting member 610. The two ends of the telescopic member are connected to the connecting section 4212 and the support frame 310, respectively, and the height of the connecting section 4212 can be adjusted by telescopic movement.

[0070] In a more specific embodiment, such as Figures 2-4 As shown, the adjusting member 610 includes a screw 611 and a head 612 disposed at one end of the screw 611. The screw 611 passes through the top of the support frame 310 and is threadedly connected to a threaded hole. The cross-sectional dimension of the head 612 is larger than the cross-sectional dimension of the through hole on the support frame 310. After the screw 611 passes through the support frame 310, the head 612 of the adjusting member 610 can abut against the top surface of the support frame 310.

[0071] The adjustment assembly 600 also includes a limiting member 620, which is sleeved on the screw 611 and threadedly connected to the screw 611. The top of the support frame 310 is limited between the head 612 and the limiting member 620.

[0072] The support frame 310 includes a frame body and a mounting section mounted on the frame body. The mounting section is located above the frame body and is detachably connected to the frame body. An adjusting member 610 passes through the mounting section of the support frame 310. Illustratively, a nut can be used as a limiting member 620. During the assembly of the hopper elevator, the adjusting member 610 is first passed through the mounting section, then the limiting member 620 is installed on the adjusting member 610, and finally the mounting section is installed on the frame body.

[0073] The adjusting member 610 is axially limited on the support frame 310 by the limiting member 620 and the head 612 of the adjusting member 610, so that when the operator rotates the adjusting member 610, the corresponding connecting section 4212 can be reliably raised and lowered.

[0074] In one embodiment, such as Figures 6-9As shown, the column 200 includes a column body 210 and a guide portion 220 disposed on the side of the column body 210. The extension direction of the guide portion 220 is parallel to the axial direction of the column body 210, and a cavity 211 is formed inside the column body 210.

[0075] The guide portion 220 can be a strip-shaped structure, with its length parallel to the axial direction of the column 210. There can be two guide portions 220, located on opposite sides of the column 210. The guide portions 220 and the column 210 can be formed into a single piece using an integral molding process.

[0076] The lifting frame 500 includes a frame 510 and a plurality of first guide wheels 520. All the first guide wheels 520 are arranged in pairs on the frame 510, and each pair of first guide wheels 520 is clamped by a guide part 220.

[0077] Schematic illustration: The frame 510 includes two side plates, located on opposite sides of the column 200. Each side plate is equipped with a pair of first guide wheels 520, arranged in a front-to-back direction. Each pair of first guide wheels 520 clamps a corresponding guide portion 220 in the front-to-back direction. The multiple first guide wheels 520 can limit the movement of the lifting frame 500 relative to the column 200 in the front-to-back direction.

[0078] In this embodiment, the lifting frame 500 can be guided by multiple first guide wheels 520, and the lifting frame 500 can smoothly rise and fall on the column 200.

[0079] In related technologies, the column 200 adopts a square or rectangular cross-section design. This cross-section shape makes it inconvenient to arrange the guide wheels of the lifting frame 500, resulting in a bulky structure for the lifting frame 500. In the material box elevator provided in this embodiment, the side of the guide portion 220 of the column 200 serves as the guide contact surface. This not only makes the structure of the lifting frame 500 more compact and efficient, and the arrangement of the first guide wheel 520 more reasonable, but also makes the overall force distribution more balanced, enhancing the stability of the material box elevator operation.

[0080] In a specific embodiment, such as Figures 7-9 As shown, the lifting frame 500 also includes a loading platform 530 and an adjustment unit 540. The loading platform 530 is disposed on the frame 510, and the guide part 220 is disposed adjacent to the loading platform 530. The loading platform 530 is located on the front side of the column 200, and the material box can be supported by the loading platform 530. The guide part 220 is located on the front side of the side of the column 210.

[0081] In each pair of first guide wheels 520, the first guide wheel 520 on the side away from the loading platform 530 is connected to the frame 510 through an adjustment unit 540. The adjustment unit 540 can drive the first guide wheel 520 connected to it to move, so as to adjust the distance between the two first guide wheels 520 in the pair.

[0082] Specifically, in each pair of first guide wheels 520, the rear first guide wheel 520 is connected to the frame 510 via an adjustment unit 540. The adjustment unit 540 can drive the connected first guide wheel 520 to move back and forth, thereby adjusting the distance between the two first guide wheels 520.

[0083] The above configuration improves the versatility of the lifting frame 500 and facilitates the adjustment of the first guide wheel 520. Furthermore, the guide portion 220 of the column 200 is positioned forward, and the adjustment unit 540 is connected to the rear first guide wheel 520, ensuring that the guide portion 220 does not obstruct the adjustment of the position of the first guide wheel 520.

[0084] In a specific embodiment, such as Figure 7 and Figure 8 As shown, the guide part 220 has a hollow structure, and the wall thickness W2 of the guide part 220 is greater than the wall thickness W1 of the column 210.

[0085] Specifically, those skilled in the art can set the specific sizes of W1 and W2 according to actual needs, and no single limitation is made here. It is understood that the guide part 220 has a thicker wall and higher structural strength. When the lifting frame 500 is connected to the column 200, the guide part 220 of the column 200 bears the load, and the guide part 220 is not easily deformed.

[0086] The above settings ensure the reliability of column 200 and control its weight.

[0087] In one embodiment, such as Figure 1 and Figure 10 As shown, the base assembly 100 includes a base 110 and a connecting seat 120 mounted on the base 110. The bottom end of the column 200 is connected to the connecting seat 120. The connecting seat 120 has a receiving cavity 121 inside, the drive wheel 410 is rotatably mounted in the receiving cavity 121, and the timing belt 430 passes through the connecting seat 120.

[0088] Wherein, the base 110 may be a plate-shaped structure, the connecting seat 120 may be locked to the top of the base 110 by fasteners, and the bottom end of the vertical column 200 may be connected to the connecting seat 120 by fasteners. The driving member of the bin hoist can be mounted on the base 110, and the output end of the driving member can pass through the side wall of the connecting seat 120 and be connected to the driving wheel 410 in the accommodating cavity 121. Illustratively, the top wall of the connecting seat 120 is provided with a hole, and the synchronous belt 430 passes through the hole and is connected to the driving wheel 410 in the accommodating cavity 121.

[0089] In this embodiment, the connecting seat 120 on the base 110 can raise the vertical column 200, and the driving wheel 410 of the synchronous belt assembly 400 can be arranged below the vertical column 200, so that the synchronous belt 430 can pass through the vertical column, which optimizes the space occupation of the bin hoist.

[0090] In a possible implementation, both the driving wheel 410 and the driven wheel 420 are gears, and the inner side of the synchronous belt 430 is provided with tooth portions 431 respectively meshed with the driving wheel 410 and the driven wheel 420.

[0091] Wherein, the tooth portions 431 can be arranged on the main body portion of the synchronous belt 430 through an integral molding process. After the tooth portions 431 of the synchronous belt 430 are respectively meshed with the driving wheel 410 and the driven wheel 420, the driving wheel 410 can reliably drive the synchronous belt 430 and the driven wheel 420 to move when rotating. The above arrangement can ensure the transmission stability of the synchronous belt assembly 400.

[0092] As Figure 11 shown, the tooth portions 431 are herringbone-shaped.

[0093] Illustratively, the tooth portions 431 include a first tooth portion and a second tooth portion, the first tooth portion and the second tooth portion are arranged side by side along the width direction of the synchronous belt 430, the first tooth portion and the second tooth portion are respectively inclined relative to the width direction of the synchronous belt 430, the inclination directions of the first tooth portion and the second tooth portion are opposite, and the first tooth portion and the second tooth portion define a herringbone shape. Correspondingly, the teeth of the driving wheel 410 and the driven wheel 420 are also herringbone-shaped.

[0094] Those skilled in the art can understand that if the synchronous belt 430 adopts common flat teeth, once deviation occurs, it is easy to cause the problem of falling off from the guide edges of the pulleys. In this embodiment, compared with common flat teeth, the herringbone tooth portions 431, on one hand, the herringbone structure can naturally form left and right limit for the synchronous belt 430 to avoid deviation during operation; on the other hand, the inclined surface design of the herringbone shape can increase the contact area between the synchronous belt 430 and the driving wheel 410 as well as the driven wheel 420, and significantly improve the transmission strength and stability under the condition of the same belt width.

[0095] 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.

[0096] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
