Description

Technical Field

[0001] The utility model relates to the field of transmission device technology, and in particular to a transmission assembly with a platform roller assembly. Background Technology

[0002] In many screen printing processes involving sheet metal, a transmission support is often needed to lift and transfer the sheet metal. Given that sheet metal typically has a large area and heavy weight, this places high demands on the mechanism used to lift the sheet metal. It must be able to automatically raise and lower the entire platform to meet the operational needs at different heights in the screen printing process.

[0003] In the current manufacturing field of lifting transmission devices, most products on the market rely on a series of mechanisms such as motors and gears to achieve the lifting action of the platform. This structural design does ensure a smooth lifting process, providing a relatively stable operating environment for screen printing on sheet metal. However, its complex mechanism also brings many problems. During the debugging phase, operators need to spend a lot of time and energy adjusting the coordination between various components to ensure that the operating parameters of the motor, gears, etc., are at their optimal state to achieve precise lifting control. In the subsequent maintenance phase, due to the large number of internal parts and complex connections, once a fault occurs, maintenance personnel often need to spend a lot of time troubleshooting the root cause of the problem. Replacing damaged parts also requires high professional skills and rich experience, which is undoubtedly a very challenging task for operators.

[0004] The technical content disclosed in the Chinese patent document (publication number: CN206476698U, patent name: a lifting transmission device) is: a lifting transmission device, including a motor, a reduction gearbox, a prime mover gearbox and an active lifting mechanism, characterized in that: the reduction gearbox has a power input end and two power output ends, wherein the power input end is connected to the motor for transmission, and the two power output ends are respectively connected to the prime mover gearbox and the active lifting mechanism for transmission.

[0005] As stated in the aforementioned document, this lifting transmission device also utilizes components such as motors and gears to achieve its lifting drive function. To a certain extent, it can ensure the smooth lifting of the platform, meeting the basic stability requirements of the screen printing process. However, its complex structural design makes debugging and maintenance extremely difficult. During debugging, multiple parameters such as motor speed and gear ratio need to be precisely adjusted; any deviation in any of these parameters can affect the performance of the entire lifting system. During maintenance, the complex internal structure increases the difficulty of troubleshooting and consequently raises maintenance costs. This situation not only leads to prolonged equipment downtime and affects production efficiency but also increases subsequent operating costs, including maintenance expenses, replacement parts costs, and production losses due to downtime. Utility Model Content

[0006] This utility model overcomes the shortcomings of the prior art and provides a transmission assembly with a platform roller assembly. This assembly is designed with a power component, a linkage component, and a lifting structure. The linkage component transmits the power of the power component to achieve the lifting of the lifting rod. The lifting rod pushes the platform frame to rise, and the platform frame lowers using its own weight. Therefore, the structure is simple, making debugging and maintenance easier, effectively shortening equipment downtime, improving production efficiency, and reducing subsequent operating costs.

[0007] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0008] A transmission assembly with a platform roller assembly includes a power assembly, a linkage assembly, a lifting structure, and a platform frame.

[0009] The linkage component includes a rotating rod, one end of which is connected to a third swing rod. The power component is used to drive the rotating rod to rotate, and the rotation of the rotating rod causes the third swing rod to swing.

[0010] The lifting structure includes a lifting base, a lifting rod slidably inserted into the lifting base, and the upper end of the lifting rod is connected to the platform frame.

[0011] The end of the third swing arm furthest from the rotating rod is positioned below the lifting rod;

[0012] When the rotating rod rotates in the first direction, the end of the third swing rod that contacts the lifting rod will lift the lifting rod, thereby raising the platform frame.

[0013] When the rotating rod rotates in the second direction, the end of the third swing rod that contacts the lifting rod descends, and the lifting rod descends due to gravity, thereby causing the platform frame to descend;

[0014] The first steering is opposite to the second steering.

[0015] Furthermore, the end of the third swing arm furthest from the rotating rod is connected to a apex bearing, and the outer edge of the apex bearing contacts the bottom end of the lifting rod.

[0016] Furthermore, the power assembly includes a central connecting rod, with a first swing arm and a second swing arm rotatably connected to both ends of the central connecting rod, respectively;

[0017] The ends of the first and second pendulums furthest from the central connecting rod are each connected to a rotating rod.

[0018] Furthermore, the end of the first swing arm that connects to the central linkage is connected to the power source;

[0019] When the power source pushes the upper end of the first pendulum rod to move, the middle connecting rod is pushed and moves along its length. The rotating rod connected to the lower end of the first pendulum rod rotates accordingly. The upper end of the second pendulum rod swings along with the movement of the middle connecting rod. At this time, the rotating rod connected to the lower end of the second pendulum rod also rotates accordingly.

[0020] Furthermore, the power source is a cylinder or an electric cylinder.

[0021] Furthermore, the platform frame is equipped with rollers.

[0022] Furthermore, the surface of the idler roller is provided with anti-slip texture to increase the friction between the idler roller and the load.

[0023] Furthermore, the upper ends of the two lifting rods are connected to a lifting crossbeam, which is connected to the platform frame, and the rollers are set perpendicular to the lifting crossbeam.

[0024] Compared with existing technologies, the advantages of this utility model are:

[0025] This structural assembly incorporates a power unit, a linkage unit, and a lifting structure. The linkage unit transmits power from the power unit to raise and lower the lifting rod. The lifting rod then raises the platform frame, which in turn lowers it using its own weight. This simple structure makes commissioning and maintenance easier, effectively reducing equipment downtime, improving production efficiency, and lowering subsequent operating costs.

[0032] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0033] like Figures 1 to 4 As shown, a transmission assembly with a platform roller assembly is used for the board lifting transmission of a screen printing machine. It includes a power assembly 1, a linkage assembly 2, a lifting structure 3, and a platform frame 4. The linkage assembly 2 includes a rotating rod 203, one end of which is connected to a third swing rod 202. The power assembly 1 is used to drive the rotating rod 203 to rotate, and the rotation of the rotating rod 203 causes the third swing rod 202 to swing.

[0034] The power assembly 1 includes a power source 101 and a connecting rod 103. The power source 101 is a cylinder or an electric cylinder. The connecting rod 103 has a first swing rod 102 and a second swing rod 104 rotatably connected to its two ends. The ends of the first swing rod 102 and the second swing rod 104 away from the connecting rod 103 are each connected to a rotating rod 203. The end of the first swing rod 102 connected to the connecting rod 103 is connected to the power source 101. When the power source 101 pushes the upper end of the first swing rod 102 to move, the connecting rod 103 is pushed and moves along its length. The rotating rod 203 connected to the lower end of the first swing rod 102 rotates accordingly. The upper end of the second swing rod 104 swings with the movement of the connecting rod 103. At this time, the rotating rod 203 connected to the lower end of the second swing rod 104 also rotates accordingly.

[0035] like Figure 3As shown, the rotating rod 203 is rotatably connected to the main frame. The rotating rod 203 only rotates during the entire linkage action and does not lift or move. When the power source 101 pushes the top of the first swing rod 102 to move, the middle connecting rod 103 will be pushed. Due to the linkage effect of the middle connecting rod 103, the first swing rod 102 and the second swing rod 104 are in a parallel state. Therefore, the top of the first swing rod 102 is pushed, and its bottom end drives the rotating rod 203 to rotate. Then the top of the second swing rod 104 is pushed by the middle connecting rod 103, and the bottom end of the second swing rod 104 also drives the rotating rod 203 connected to it to rotate. The rotation of the two parallel rotating rods 203 will cause all the third swing rods 203 connected to the rotating rod 203 to swing.

[0036] The lifting structure 3 includes a lifting base 301, a lifting rod 302 is slidably inserted into the lifting base 301, and the upper end of the lifting rod 302 is connected to the platform frame 4; the end of the third swing rod 202 away from the rotating rod 203 is located below the lifting rod 302.

[0037] When the rotating rod 203 rotates in the first direction, the end of the third swing rod 202 that contacts the lifting rod 302 will lift the lifting rod 302, thereby raising the platform frame 4;

[0038] When the lever 203 rotates in the second direction, the end of the third lever 202 that contacts the lifting lever 302 descends. The lifting lever 302 descends due to gravity, causing the platform frame 4 to descend. As the platform frame 4 descends, the third lever 202 also abuts against the bottom end of the lifting lever 302, causing the platform frame 4 to descend slowly. The first direction is opposite to the second direction; therefore, the action of the power source 101 driving the first lever 102 to rotate is ultimately converted into the action of the third lever 202 pushing the lifting lever 302 to rise and fall at its bottom end.

[0039] In this embodiment, six sets of lifting structure components 3 are provided. Every two sets of lifting structure components 3 are connected to a lifting crossbeam 304 at their upper ends, and every three sets of lifting structure components 3 are connected to a rotating rod 203, thus forming a support surface that is square in top view. The lifting crossbeam 304 is connected to the platform frame 4, and the platform frame 4 is provided with rollers 401, so that the board material can be placed stably on the platform frame 4. The surface of the rollers 401 is provided with anti-slip texture to increase the friction between the rollers 401 and the load. The rollers 401 are set perpendicular to the lifting crossbeam 304, so that the board material can be moved by rotating the rollers 401 when it needs to be transferred.

[0040] The end of the third rocker arm 202 furthest from the rotating rod 203 is connected to a apex bearing 303. The outer edge of the apex bearing 303 contacts the bottom end of the lifting rod 302. This point contact method can effectively reduce the friction between the third rocker arm 202 and the lifting rod 302, making the third rocker arm 202 push the lifting rod 302 up or down more smoothly, and also improving the operating efficiency and stability of the entire transmission assembly.

[0041] Compared to traditional lifting transmission systems, which require precise adjustments to multiple parameters such as motor speed and gear ratio during commissioning and are difficult to troubleshoot during maintenance, this transmission assembly has a relatively simple structure. This assembly consists of a power component, a linkage component, and a lifting structure. The linkage component transmits the power from the power component to raise and lower the lifting rod. The lifting rod then pushes the platform frame to rise, and the platform frame lowers using its own weight. Therefore, the simple structure makes commissioning and maintenance easier, effectively reducing equipment downtime, improving production efficiency, and lowering subsequent operating costs.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
