Description

Technical Field

[0001] This invention relates to the field of food machinery products technology, and more specifically to a transport device. Background Technology

[0002] In the field of material conveying technology, synchronous belt transmission mechanisms are widely used due to their advantages such as smooth transmission and compact structure. Traditional conveying devices typically use a fixed connection, with the conveyor rigidly mounted directly on the synchronous belt. When the drive source rotates the synchronous belt, the conveyor moves synchronously with the belt, thus achieving continuous material conveying. However, because the conveyor cannot be quickly separated from the synchronous belt in the integrated connection structure, when the conveyor malfunctions during transportation and needs repair, or when it needs cleaning due to surface contamination, operators cannot handle the conveyor individually but must disassemble the entire conveying device, resulting in cumbersome and time-consuming maintenance operations.

[0003] Especially in the catering industry, there are extremely high standards for food hygiene and safety. As components that come into direct contact with food or tableware, the frequency of cleaning and disinfection of transport vehicles is much higher than in ordinary industrial settings. Frequent disassembly and assembly of the entire machine seriously occupies business hours, reduces operational efficiency, and increases labor maintenance costs, making it difficult to meet the catering industry's urgent need for easy-to-clean and high-efficiency equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a transportation device to solve the technical problem of cumbersome and inefficient maintenance operations caused by the direct connection between the transportation vehicle and the timing belt in traditional transportation devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transport device, disposed on a workbench, with a support frame provided below the workbench, comprising:

[0007] A limiting guide rail is provided on the support frame;

[0008] A drive mechanism, mounted on the support frame, includes a synchronous belt, a drive assembly, and several guide assemblies. The synchronous belt is adapted to and installed with the limiting guide rail. The drive assembly drives the synchronous belt to rotate in a ring. The guide assembly includes a limiting group and a magnetic synchronizing element. One end of the limiting group near the worktable is connected to the magnetic synchronizing element, and the other end of the limiting group near the limiting guide rail is slidably connected to the limiting guide rail. The magnetic synchronizing element is connected to the outer wall of the synchronous belt and moves synchronously with the synchronous belt.

[0009] A transport mechanism is provided on the upper surface of the workbench and includes several adsorbed carriers corresponding to the magnetic synchronization element. The adsorbed carriers move synchronously with the magnetic synchronization element.

[0010] In one embodiment, the worktable is made of a non-ferromagnetic material, and the adsorbed carrier is made of a magnetic material or ferromagnetic substance that is adsorbed to the opposite pole of the magnetic synchronization element.

[0011] In one embodiment, the adsorbed carrier is provided with a rolling assembly at one end near the worktable, and the rolling assembly is rotatably connected to the upper surface of the worktable.

[0012] In one embodiment, a first limiting groove is provided on the upper surface of the worktable, the extension direction of the first limiting groove is corresponding to the movement direction of the magnetic synchronization component, and one end of the adsorbed carrier near the worktable is embedded in the first limiting groove.

[0013] In one embodiment, the workbench is further provided with a drainage trough, which is connected to the first limiting groove, and the drainage trough is provided with a drainage outlet.

[0014] In one embodiment, the limiting guide rail is provided with two sets of second limiting grooves symmetrically on the side near the synchronous belt and the side away from the synchronous belt; the limiting group includes a plurality of guide members, and at least one set of the guide members is nested on each of the two sets of second limiting grooves, and the outer surface of the guide member abuts against the inner wall surface of the second limiting groove.

[0015] In one embodiment, the magnetic synchronizing element has a first latching member at one end near the synchronizing belt, and the synchronizing belt has a corresponding second latching member that is detachably connected to the first latching member.

[0016] In one embodiment, the support frame is slidably connected to the worktable via a slide rail mechanism. The slide rail mechanism includes a fixing member and a sliding member slidably mounted on the fixing member. The fixing member is connected to the worktable, and the sliding member is connected to one end of the support frame near the fixing member. The sliding member is used to drive the support frame to slide relative to the worktable.

[0017] In one embodiment, the drive assembly includes a drive motor, a main synchronous pulley, and a slave synchronous pulley. The main synchronous pulley is connected to the output end of the drive motor, and the slave synchronous pulley is rotatably connected to the support frame. The central axes of the main synchronous pulley and the slave synchronous pulley are both perpendicular to the upper surface of the worktable, and the synchronous belt is wound around the main synchronous pulley and the slave synchronous pulley.

[0018] In one embodiment, a tensioning mechanism is further provided between the main synchronous pulley and the slave synchronous pulley, the tensioning mechanism being used to adjust the tension of the synchronous belt.

[0019] As can be seen from the above technical solutions, the present invention has the following advantages:

[0020] By installing a sliding guide assembly on the limiting guide rail, including a magnetic synchronizing element, and cooperating with the adsorbed carrier positioned on the worktable corresponding to the magnetic synchronizing element, the magnetic synchronizing element can drive the adsorbed carrier to move synchronously when the drive mechanism drives the synchronous belt to rotate. This utilizes magnetic adsorption to replace the traditional rigid connection, achieving non-contact transmission and rapid separation between the adsorbed carrier and the drive mechanism. When cleaning or maintenance of the adsorbed carrier is required, the operator only needs to overcome the magnetic force to remove the carrier directly, eliminating the need for the cumbersome disassembly of the entire transport device as required by traditional devices. This improves the convenience of equipment maintenance and operational efficiency, effectively solving the problems of difficult equipment maintenance and long downtime in high-frequency cleaning scenarios such as the catering industry, and reducing labor maintenance costs.

[0031] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0032] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] First, it should be noted that the transportation device disclosed in this application is mainly used in the catering industry, and more specifically, it can be used to transport cups that carry beverages or beverage materials.

[0035] See Figures 1 to 6As shown in the illustration, this invention discloses a transport device mounted on a workbench 1. The workbench 1 has several workstations, each used to inject different types of liquid or solid materials into a cup 6. The transport device transports the cup 6 sequentially through these workstations and stops at the corresponding workstation according to order requirements, thus achieving the injection of the required materials. This automated transport method simulates the manual pouring of beverages, providing a variety of different beverages according to consumer preferences. This not only improves the efficiency of beverage preparation but also meets the market demand for personalized beverage services.

[0036] Furthermore, the transport device includes a limiting guide rail 2, a drive mechanism 3, and a transport mechanism 4. A support frame 11 is provided below the worktable 1, and the limiting guide rail 2 is fixedly mounted on the support frame 11. The drive mechanism 3 is located on the support frame 11 and includes a synchronous belt 31, a drive assembly 32, and several guide assemblies 33. The synchronous belt 31 is spatially adapted to the limiting guide rail 2, and the drive assembly 32 drives the synchronous belt 31 to rotate in a ring. The guide assembly 33 consists of a limiting group and a magnetic synchronizing element 332. One end of the limiting group is connected to the magnetic synchronizing element 332, and the other end is slidably connected to the limiting guide rail 2. The magnetic synchronizing element 332 is connected to the outer wall of the synchronous belt 31, thus enabling it to move synchronously with the synchronous belt 31. The transport mechanism 4 is located on the upper surface of the worktable 1 and includes multiple adsorbed carriers 41, each corresponding to a magnetic synchronizing element 332. During operation, the adsorbed carriers 41 are coupled to the magnetic synchronizing elements 332 via magnetic force, thereby achieving synchronous movement. It is understood that in this embodiment, the adsorption carrier 41 is used to support the cup body 6.

[0037] Specifically, in this embodiment, non-contact magnetic force transmission between the magnetic synchronizing element 332 and the adsorbed carrier 41 replaces traditional rigid connection methods such as bolts or clips. During operation, the drive assembly 32 starts, driving the synchronous belt 31 to rotate cyclically. The synchronous belt 31 drives the magnetic synchronizing element 332 connected to it to move synchronously. The magnetic synchronizing element 332 slides along the limiting guide rail 2 under the guidance of the limiting group. At the same time, the magnetic force generated by the magnetic synchronizing element 332 penetrates the worktable 1, adsorbing the adsorbed carrier 41 above, causing it to move along with it, thereby completing the conveying of the cup 6. When it is necessary to clean or replace the adsorbed carrier 41, or clean or maintain the surface of the worktable 1, it is only necessary to lift the adsorbed carrier 41 from the worktable 1 and overcome the magnetic force to achieve quick separation without disassembling any transmission components, which greatly simplifies the maintenance process.

[0038] It should be noted that in this embodiment, the workbench 1 is made of a non-ferromagnetic material, such as aluminum alloy, austenitic stainless steel, or engineering plastics. The material of the adsorbed carrier 41 is a magnetic material capable of generating opposite pole adsorption with the magnetic synchronization element 332, such as a permanent magnet, or a ferromagnetic material, such as low-carbon steel. On the one hand, the material of the workbench 1 needs to ensure that magnetic lines of force can effectively penetrate the workbench 1. On the other hand, without interfering with the magnetic field distribution, a stable magnetic adsorption force is established between the magnetic synchronization elements 332 on the upper and lower sides of the workbench 1 and the adsorbed carrier 41. This allows the magnetic synchronization element 332 located below the workbench 1 to reliably adsorb the ferromagnetic or magnetic adsorbed carrier 41 above, thereby ensuring the reliability of power transmission while maintaining the integrity and flatness of the workbench 1 surface, facilitating cleaning, and preventing the workbench 1 itself from being magnetized and attracting impurities such as iron filings.

[0039] Furthermore, a rolling assembly 411 is provided on one end of the adsorbed carrier 41 near the worktable 1.

[0040] Specifically, the rolling assembly 411 directly contacts the upper surface of the worktable 1 and forms a rolling connection, thereby converting the sliding friction between the adsorbed carrier 41 and the worktable 1 into rolling friction, significantly reducing motion resistance. During operation, when the adsorbed carrier 41 is adsorbed and driven by the magnetic synchronization component 332, the rolling assembly 411 at its bottom rolls on the surface of the worktable 1, thus supporting the carrier to move smoothly forward. The movement of the adsorbed carrier 41 is also smoother and lighter, reducing the load on the drive mechanism 3, which helps to improve the motion stability and energy efficiency of the entire device, while reducing wear and noise caused by friction.

[0041] It is understood that in this embodiment, the rolling assembly 411 is preferably a ball bearing structure, which includes a ball socket fixed to the bottom of the adsorbed carrier 41 and a plurality of balls rotatably mounted in the ball socket. Part of the spherical surface of the ball protrudes from the ball socket and rolls in contact with the upper surface of the worktable 1, thereby converting the sliding friction between the adsorbed carrier 41 and the worktable 1 into rolling friction. In other embodiments, the rolling assembly 411 may also be a roller structure or a universal wheel structure, as long as it is ensured that the adsorbed carrier 41 can follow the movement trajectory of the magnetic synchronizing element 332 driven by the synchronous belt 31 to move in a straight line or turn, and no specific limitation is made here.

[0042] In one embodiment, the drive assembly 32 includes a drive motor 321, a main synchronous pulley 322, and a driven synchronous pulley 323. The drive motor 321 is fixed to the support frame 11, and its output shaft is connected to the main synchronous pulley 322 via a coupling. The driven synchronous pulley 323 is rotatably connected to another position on the support frame 11 via a rotary bearing. The synchronous belt 31 is wrapped around the main synchronous pulley 322 and the driven synchronous pulley 323.

[0043] Specifically, in this embodiment, the rotational motion of the drive motor 321 is converted into the cyclic motion of the synchronous belt 31. After the drive motor 321 is started, it drives the main synchronous pulley 322 to rotate. Through the meshing transmission of the synchronous belt 31, it drives the secondary synchronous pulley 323 to rotate synchronously, thereby making the entire synchronous belt 31 perform a circular motion.

[0044] Understandably, in one possible implementation of this embodiment, several workstations on the workbench 1 are arranged in a straight line, and the transport device is configured to transport the cup 6 carrying the beverage along a straight trajectory. To accommodate this straight-line transport requirement, the main synchronous pulley 322 and the direction extending from the central axis of the synchronous pulley 323 in the drive mechanism 3 are designed to be parallel to the workbench 1 surface, allowing the synchronous belt 31 to be horizontally deployed. When the drive motor 321 starts, its power is transmitted to the main synchronous pulley 322, driving the synchronous belt 31 to rotate in a straight line, which in turn drives the attracted carrier 41 to reciprocate along a straight line on the workbench 1 via the magnetic synchronizing element 332. This straight-line distribution structure design is simple and compact, occupies little space, and facilitates operation or monitoring by operators on both sides of the workbench 1. It also facilitates the rapid flow of the cup 6 between the linearly arranged workstations, enabling efficient completion of material injection tasks under a straight-line process flow. However, this form of linear transportation requires the addition of a step to remove the adsorbed carrier 41 from the end station and reposition it at the starting station. This still requires manual intervention or the addition of corresponding automated mechanisms, and thus has certain limitations. It is only suitable for application scenarios with relatively simple process steps or limited space.

[0045] In another possible implementation of this embodiment, the workstations on the workbench 1 are preferably designed in a circular arrangement. This layout effectively utilizes the surface area of ​​the workbench 1, thereby increasing the number of workstations and the number of workstations waiting for the cups 6 to be transported. On the one hand, it can prevent the waiting time for picking up and delivering the cups 6 from affecting the overall working efficiency of the unloading equipment. On the other hand, it can also realize that the adsorbed carrier 41 can only be removed when cleaning or maintenance of the adsorbed carrier 41 or the workbench 1 is required, without excessive manual intervention or the addition of an extra transport mechanism 4 for transporting the adsorbed carrier 41. In this embodiment, the main synchronous pulley 322 and the extension direction of the central axis of the synchronous pulley 323 are designed to be perpendicular to the surface of the workbench 1, so that the synchronous belt 31 can form a horizontal circular transmission loop. The drive motor 321 drives the synchronous belt 31 to move along the circular path, thereby driving the adsorbed carrier to move synchronously along the movement trajectory of the synchronous belt 31. This circular design allows the cup body 6 to pass through more processing stations within a limited countertop space, greatly enriching the beverage making process, improving the integration of the equipment and the space utilization rate, and making it particularly suitable for beverage making scenarios with complex processes and a wide variety of materials.

[0046] It should be noted that, in this embodiment, the working status of each actuator in the transportation device is uniformly regulated by the control system, which issues start / stop and operation commands according to the preset working logic to achieve coordinated and orderly operation of each component. It is understood that the control system and control method mentioned in this application are easily implemented by those skilled in the art. The main description in this application focuses on the structure of the transportation device, not the control method. The mention of the control system is merely for the convenience of explaining the working principle of the transportation device. The control system includes, but is not limited to, a PLC control system.

[0047] In this embodiment, the drive motor 321 is preferably a servo motor. Through the closed-loop control characteristics of the servo motor, the rotation angle or number of rotations can be precisely set based on actual on-site needs, such as the specific layout spacing of different workstations and the process paths of different orders. This ensures that each adsorbed carrier 41 can accurately stop at its corresponding workstation. During operation, the control system sends precise motion commands to the servo motor according to a preset program or real-time received order instructions. This drives the synchronous belt 31 to move the adsorbed carrier 41 a specific distance, ensuring that the adsorbed carrier 41 can accurately stop at its corresponding workstation, achieving precise docking with the unloading equipment and completing the unloading operation. This significantly improves the automation level of beverage production and the finished product qualification rate.

[0048] In other embodiments, to further improve the positioning accuracy and automation control level of the transport device, a position sensor can be added. Specifically, a position sensor is installed on the magnetic synchronization element 332, which includes a sensing baffle 3322 on the magnetic synchronization element 332 and a photoelectric sensor 111 on the support frame 11. Since the magnetic synchronization element 332 and the attracted carrier 41 maintain synchronous movement through magnetic attraction, the position information of the attracted carrier 41 can be obtained in real time and accurately by detecting the position of the magnetic synchronization element 332. The position sensor can feed back the detected position signal to the control system in real time. The control system determines whether the attracted carrier 41 has accurately reached the designated workstation by comparing it with the preset workstation position data. If a position deviation is detected, the control system can adjust the action of the drive motor 321 in a timely manner to fine-tune the position of the attracted carrier 41, thereby ensuring that the attracted carrier 41 can accurately stop at the corresponding workstation, thus ensuring the accuracy and stability of subsequent unloading operations and improving the operational reliability of the entire system. It is understood that in this embodiment, each magnetic synchronization element 332 is provided with a sensing baffle 3322. Preferably, only one set of photoelectric sensors 111 is set at the end station, that is, only the state of each adsorbed carrier 41 after passing the end station is recorded, and the position of each adsorbed carrier 41 is mainly controlled by a servo motor, thereby reducing the amount of data in the control system and simplifying the overall control logic. In other embodiments, the number of photoelectric sensors 111 can be increased or photoelectric sensors 111 can be set for each station according to actual needs, thereby further ensuring the full-process monitoring of the adsorbed carrier 41. No specific limitation is made here.

[0049] Furthermore, to compensate for the potential plastic elongation or loosening of the synchronous belt 31 after long-term use, and to meet the initial tension adjustment requirements during installation, the drive mechanism 3 is also equipped with a tensioning mechanism 34. The tensioning mechanism 34 is located between the main synchronous pulley 322 and the driven synchronous pulley 323. During operation, by adjusting the position of the tensioning mechanism 34, tension can be applied or released to the synchronous belt 31, ensuring it maintains an appropriate tension. This effectively prevents the synchronous belt 31 from slipping or skipping teeth due to excessive looseness, or from experiencing increased wear and load due to excessive tightness. This ensures long-term stability of transmission efficiency, extends the service life of the synchronous belt 31, the main synchronous pulley 322, and the driven synchronous pulley 323, and ensures the accuracy of power transmission. It is understood that in this embodiment, the tensioning mechanism 34 can be an adjustable idler pulley structure, or a sliding mechanism that adjusts the shaft position of the driven synchronous pulley 323, etc. The specific form can be adaptively selected and set according to actual needs, as long as it can adjust the tension of the synchronous belt 31; no specific limitation is made here.

[0050] In one embodiment, a first limiting groove 12 is provided on the surface of the worktable 1. The first limiting groove 12 is machined or formed on the upper surface of the worktable 1, and its extension direction strictly corresponds to the movement direction of the magnetic synchronization member 332 along the limiting guide rail 2. That is, in this embodiment, the first limiting groove 12 is an annular groove provided on the surface of the worktable 1. The end of the adsorbed carrier 41 near the worktable 1 is designed to be embedded in the first limiting groove 12. That is, the size of the adsorbed carrier 41 should correspond to the first limiting groove 12, thereby ensuring that the channel structure of the first limiting groove 12 limits and guides the adsorbed carrier 41 on the horizontal plane, preventing it from deviating or twisting during movement. During operation, when the adsorbed carrier 41 moves under magnetic traction, the part of it embedded in the first limiting groove 12 is constrained by the groove wall and can only move along the preset path. This effectively makes up for the deficiency that the simple magnetic adsorption may not be able to limit the horizontal direction, ensuring that each adsorbed carrier 41 can run along a precise trajectory and avoiding the adsorbed carrier 41 from deviating in direction during operation.

[0051] Furthermore, a drainage trough 13 is provided on the workbench 1. It is understood that the drainage trough 13 is typically a groove lower than the workbench surface and is interconnected with the first limiting groove 12. One or more drain outlets are provided at the lowest point or end of the drainage trough 13 to guide liquid to an external wastewater collection point. This adapts to the high-frequency cleaning scenarios in the catering industry, utilizing the principle of gravity flow to collect and discharge cleaning wastewater. During operation, when the workbench 1 needs to be rinsed or wiped, the adsorbed carrier 41 is first removed from the workbench 1. Then, the workbench surface and the first limiting groove 12 are cleaned manually or by an external cleaning mechanism, and the generated wastewater is guided into the first limiting groove 12. The wastewater then flows along the connected path into the drainage trough 13 and is finally discharged from the drain outlet. This effectively prevents wastewater from accumulating on the workbench 1 surface, greatly facilitating daily cleaning and maintenance, quickly restoring the dryness and hygiene of the work area, and meeting the high hygiene standards required by the industry for easy cleaning of equipment.

[0052] In one embodiment, the limiting guide rail 2 has two sets of second limiting grooves 21 symmetrically machined on the side closer to the synchronous belt 31 and the side farther away from the synchronous belt 31. The limiting set is composed of multiple independent guide members 331.

[0053] Specifically, during installation, at least one guide member 331 is nested in each of the two sets of second limiting grooves 21, with the outer surface of the guide member 331 in contact or slightly abutting against the inner wall of the second limiting groove 21. This symmetrically distributed double-groove nesting structure provides bidirectional constraint to the limiting assembly, restricting its movement in all degrees of freedom except the direction of motion. During operation, the guide member 331 slides within the second limiting groove 21. Due to the constraint of the side groove walls, the entire guiding assembly 33 and the connected magnetic synchronization member 332 are ensured to translate along the length of the guide rail, reducing the possibility of vertical swaying and thus laying a solid foundation for the smooth transport of the above-adsorbed carrier 41.

[0054] It is understood that in this embodiment, the guide member 331 preferably adopts a roller assembly structure. These roller assemblies are nested in the second limiting grooves 21 symmetrically arranged on both sides of the limiting guide rail 2, and the outer peripheral surface of the roller assembly forms rolling contact with the inner wall surface of the second limiting groove 21. Simultaneously, the coordinated rolling of the symmetrically arranged roller assemblies within the second limiting grooves 21 on both sides provides stable lateral support for the guide member 33, preventing it from tilting or bouncing during movement, and ensuring the straightness and stability of the magnetic synchronization member 332's movement trajectory. In other embodiments, the guide member 331 can also be selected from other structures corresponding to the second limiting grooves 21, such as sliders, as long as the second limiting grooves 21 can effectively limit and guide it; no specific limitations are made here.

[0055] Furthermore, a first engaging member 3321 is provided at the end of the magnetic synchronizing member 332 near the timing belt 31, and a second engaging member 311, matching the first engaging member 3321, is provided at the position on the timing belt 31 corresponding to each magnetic synchronizing member 332. The first engaging member 3321 and the second engaging member 311 can be detachably connected by means of plugging, snapping, or twisting, thereby allowing the magnetic synchronizing member 332 to be connected to the transmission component as an independent module. During operation, when the timing belt 31 rotates, the power is reliably transmitted to the magnetic synchronizing member 332 through the cooperation of the first engaging member 3321 and the second engaging member 311. When a magnetic synchronizing member 332 needs to be replaced or maintained, the operator can manually release the engagement and remove it from the timing belt 31 without disassembling the timing belt 31 or other components, making the maintenance of the transmission component more convenient.

[0056] It is understood that in this embodiment, the first snap-fit ​​member 3321 is preferably in the form of a snap-fit ​​post, and the second snap-fit ​​member 311 is correspondingly configured as a mounting base structure with a snap-fit ​​groove. During installation, the snap-fit ​​post is inserted into the snap-fit ​​groove from one end and fixed in the snap-fit ​​groove, completing the connection between the magnetic synchronization member 332 and the synchronization belt 31. When disassembly is required, the snap-fit ​​post can be slid out from one end of the snap-fit ​​groove. In other embodiments, the structural forms of the first snap-fit ​​member 3321 and the second snap-fit ​​member 311 can also be adaptively designed according to actual needs, and no specific limitation is made here.

[0057] In one embodiment, the connection between the support frame 11 and the worktable 1 is designed to be slidable via a slide rail mechanism 5. This slide rail mechanism 5 includes a fixing member 51 and a sliding member 52.

[0058] Specifically, the fixing member 51 is connected to the bottom or side of the workbench 1, and the sliding member 52 is slidably mounted on the fixing member 51, and the sliding member 52 is connected to the end of the support frame 11 near the fixing member 51. By pulling or pushing the support frame 11, the sliding member 52 can slide along the fixing member 51. In this embodiment, the drive mechanism 3 and the transmission mechanism become a movable mounting base by means of the support frame 11, which can slide relative to the workbench 1, to expose the maintenance space that is usually covered. When it is necessary to inspect the drive mechanism 3, the timing belt 31, or the limit rail 2 below, the slide rail mechanism 5 can be operated to pull the entire support frame 11 along with all the components on it out from under the workbench 1. This makes all components fully exposed within a visible and accessible range, facilitating comprehensive inspection, cleaning, replacement, or tension adjustment, greatly improving the convenience of deep maintenance of the equipment.

[0059] It is understood that, in this embodiment, preferably, the fixing member 51 is a slide rail, which is set at the bottom or side of the worktable 1 to provide a stable guiding reference; the sliding member 52 is a sliding block corresponding to the slide rail, which is fixedly connected to the end of the support frame 11 near the fixing member 51 to form a movable support base. During operation, the operator only needs to apply force to pull the support frame 11, and the sliding block will move smoothly along the extension direction of the slide rail, thereby driving the entire support frame 11 and all the drive mechanisms 3, limit guide rails 2 and magnetic synchronization members 332 installed on it to slide out relative to the worktable 1. In other embodiments, the sliding member 52 can also be designed as another set of slide rail structures or other structural forms corresponding to the slide rail, which is not specifically limited here.

[0060] In summary, the working process of the transportation device in this embodiment is as follows:

[0061] When the cup 6 needs to be transported, the drive motor 321 starts, driving the main synchronous pulley 322 to rotate. The tension of the synchronous belt 31, adjusted by the tensioning mechanism 34, drives the synchronous pulley 323 to rotate, realizing the cyclic operation of the synchronous belt 31. The synchronous belt 31 drives the first locking member 3321 through the second locking member 311 on it, so that the magnetic synchronizing member 332 gets power. Under the guidance of the guide member 331, the magnetic synchronizing member 332 slides stably along the second limiting groove 21 on the limiting guide rail 2. The magnetic field generated by the magnetic synchronizing member 332 penetrates the worktable 1 and attracts the attracted carrier 41 on the worktable 1. The rolling component 411 at the bottom of the attracted carrier 41 rolls on the surface of the worktable 1. At the same time, the bottom of the attracted carrier 41 is embedded in the first limiting groove 12 of the worktable 1, so it is precisely guided and moves synchronously with the magnetic synchronizing member 332 to complete the transport of the cup 6.

[0062] When it is necessary to clean the workbench 1 and the transport device, the adsorbed carrier 41 can be directly removed for rinsing, and the workbench 1 can be rinsed or wiped at the same time. Wastewater can flow into the drainage trough 13 through the first limiting groove 12 and be discharged from the drain outlet.

[0063] When in-depth maintenance is required on the drive mechanism 3 and transmission components at the bottom of the workbench 1, the support frame 11 can be pulled out through the slide rail mechanism 5 to carry out a comprehensive overhaul of the drive mechanism 3.

[0064] In other words, the transportation device in this embodiment achieves easy maintenance and cleaning through magnetic connection and modular quick-release design. Unlike traditional devices, it does not require cumbersome disassembly of the entire transportation device, which improves the convenience of equipment maintenance and operating efficiency. It effectively solves the problems of difficult equipment maintenance and long downtime in high-frequency cleaning scenarios such as the catering industry, and reduces labor maintenance costs.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
