Technical Field
[0001] This utility model relates to the technical field of mechanical transmission, and more specifically, to a synchronous opposite-direction transmission module and device. Background Technology
[0002] Transmission devices are commonly used in various precision machining machines, such as CNC machining centers and 3D printers, and their main function is to transfer and move objects. Based on the object movement requirements, transmission devices can be divided into transfer devices or docking devices. The former requires only one moving part, while the latter requires two synchronously moving parts in opposite directions.
[0003] Existing transmission devices generally use lead screw drives. If a docking requirement is needed, a set of left- or right-hand lead screws can be used to achieve the requirement. However, using left- or right-hand lead screws to achieve docking will have the following problems:
[0004] 1. The left and right screw rods are usually connected by flanges or other connectors, which results in a gap between the two screw rods. When the device is used to connect with certain objects, this gap will cause the connection to fail.
[0005] 2. The cost of using screw drive is high, as is the subsequent maintenance cost.
[0006] Based on the above problems, we propose a transmission device that uses belt drive, which can achieve complete docking of left and right moving parts, and at the same time, the maintenance cost of replacing the belt is low. Summary of the Invention
[0007] To overcome the technical problems mentioned in the background art, this utility model provides a synchronous opposite-direction transmission module and its application device.
[0008] The synchronous opposite transmission module of this application includes a belt and pulleys, with the two pulleys respectively driven and installed at both ends of the inner side of the belt;

[0015] Preferably, the bottom sides of the inner wall of the connecting plate are provided with mounting grooves, and the two ends of the lower layer of the belt are assembled and fixed in the mounting grooves at both ends of the bottom of the inner wall of the connecting plate by fixing blocks and bolts; the upper layer of the belt is assembled and fixed to the upper end face of the first slider by fixing blocks and bolts.
[0016] Preferably, the mounting groove is also provided with multiple "S"-shaped grooves extending along the direction of belt movement.

[0020] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0021] This utility model provides a synchronous opposite-direction transmission module and its application device, which solves the problem that two moving parts cannot fit together in existing docking transmission devices. Furthermore, the use of belt drive results in low cost and easy maintenance. Specific advantages include:
[0022] 1. Fix a slider on the upper and lower layers of a belt, with one slider located on the left side of the upper layer and the other on the right side of the lower layer. When the belt rotates, the two sliders will move synchronously in opposite directions, and when the sliders approach each other, they will eventually fit together.

It is understandable that some well-known structures and their descriptions may be omitted in the accompanying drawings for those skilled in the art.
[0037] Unless otherwise expressly specified and limited, the terms "installation," "setting," "connection," and "fixation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Example
[0038] Please see Figure 2 This application provides a synchronous opposite-direction transmission module, including: a belt 1 and pulleys 2, with the two pulleys 2 respectively installed on the inner ends of the belt 1; the belt 1 and the two pulleys 2 constitute a belt pulley structure, and at the same time, when the upper layer of the belt 1 moves, the lower layer of the belt 1 always moves in the opposite direction to the upper layer of the belt 1.
[0039] The first slider 4 and the second slider 5 are fixedly installed on the upper and lower layers of the belt 1, respectively. The first slider 4 and the second slider 5 are arranged opposite to each other in the length direction of the belt 1 and synchronously in opposite directions. Based on the above-mentioned movement principle of the belt 1 and the pulley 2, when the first slider 4 and the second slider 5 move in opposite directions, the opposite surfaces of the first slider 4 and the second slider 5 can be connected.
[0040] Motor 10, motor 10 is connected to a pulley 2 and drives belt 1 to rotate, wherein,
[0041] Based on the above connection of belt 1 and pulley 2, in order to ensure the service life of belt 1, when the belt 1 experiences material fatigue, its tension will decrease. Therefore, a break is provided on belt 1. The two ends of the break of belt 1 are fixed on the first slider 4 or the second slider 5. When it is necessary to adjust the tension, a portion is removed from one end of belt 1, and the tension of the entire belt 1 can be adjusted.
[0042] Based on the above, in order to increase the friction between belt 1 and pulley 2, such as Figure 1 As shown, multiple racks perpendicular to the direction of movement of the belt 1 are evenly arranged around the surface of the pulley 2 and around the inner wall of the belt 1. The racks are meshed to replace friction transmission, ensuring transmission accuracy and avoiding slippage due to high load on the slider.
[0043] Based on the above, in order to ensure that the first slider 4 and the second slider 5 can be smoothly and securely connected to the upper and lower layers of the belt 1, as follows: Figure 5 As shown, a U-shaped connecting plate 12 is fixedly connected to the bottom of the second slider 5. The lower layer of the belt 1 is fixed to the bottom of the inner wall of the connecting plate 12. The bottom of the second slider 5 is extended by the U-shaped connecting plate 12, and the lower layer of the belt 1 is fixed to the bottom of the extended inner wall of the connecting plate 12 to ensure the transmission posture of the belt 1 and make the upper and lower layers of the belt 1 parallel.
[0044] Furthermore, to ensure the secure fastening effect at both ends of belt 1, such as... Figure 6 As shown, mounting grooves 6 are provided on both sides of the upper end face of the first slider 4. The two ends of the upper layer of the belt 1 are fixed to the mounting grooves 6 at both ends of the upper part of the first slider 4 by fixing blocks 7 and bolts. The lower layer of the belt 1 is fixed to the bottom of the inner wall of the connecting plate 12 by fixing blocks 7 and bolts. The fixing blocks 7 and bolts are used to fix the end of the belt 1 and install the end of the belt 1 into the mounting groove 6, which further ensures the fixing effect of the end of the belt 1. Compared with fixing with glue, it can play a good role in preventing detachment and facilitates replacement and maintenance.
[0045] Based on any of the above embodiments, such as Figure 7 As shown, the mounting groove 6 is also provided with multiple "S"-shaped grooves 3 extending along the moving direction of the belt 1. After the fixing block 7 is installed, part of the belt 1 is squeezed into the groove 3. During the transmission process, the material of the belt 1 that enters the groove 3 can improve the connection effect and prevent the belt 1 from falling off.
[0046] The specific principle of the above embodiment is as follows: When an object is placed on the first slider 4 and the second slider 5, when the drive motor 10 is activated, the pulley 2 on one side of the motor 10 rotates, thereby driving the belt and the pulley on the other side to rotate. During the rotation of the belt 1, the first slider 4 located on the upper layer of the belt 1 and the second slider located on the lower layer of the belt 1 move synchronously in opposite directions, allowing the objects on the two sliders to dock or separate. When it is necessary to adjust the tension, the fixing block 7 at the mounting slot 6 position is removed from the first slider 4 by disassembling the bolts, and a portion of the belt 1 end position is reduced to adjust the tension of the belt 1. Only one side of the belt 1 end can be disassembled.
[0047] When belt 1 needs to be completely replaced, after removing the upper port of belt 1, remove the fixing block 7 at the connecting plate 12 to completely replace belt 1. Example
[0048] Based on the above embodiments, the difference lies in, as Figure 7 As shown, in this embodiment, the end of belt 1 is adjusted to the lower layer, and the mounting groove 6 is also set at the bottom of the inner wall of the connecting plate. The upper layer of belt 1 is directly fixed to the upper end of the first slider 4 by fixing block 7. Specifically, mounting grooves 6 are set on both sides of the bottom of the inner wall of the connecting plate 12. The two ends of the lower layer of belt 1 are fixed to the mounting grooves 6 at both ends of the bottom of the inner wall of the connecting plate 12 by fixing block 7 and bolts. The upper layer of belt 1 is fixed to the upper end face of the first slider 4 by fixing block 7 and bolts.
[0049] The upper layer of belt 1 is directly fixed to the upper end of the first slider 4 via fixing block 7. (This is not shown in the attached diagram, but those skilled in the art can directly determine this from the diagram.) Figure 5 In the previous embodiment, the lower layer of belt 1 was directly installed to the lower part of the inner wall of the connecting plate 12. The upper layer of belt 1 was installed to the upper end of the first slider 4. In embodiment 2, only the position of the break of belt 1 changed. The shape changes of the other first slider 4 and second slider 5 can be directly achieved by the transformation of embodiment 1. This application will not elaborate further here. Example
[0050] like Figure 1 , Figure 3 and Figure 4 As shown, this application also provides an application device for a synchronous opposite-direction transmission module, which can also be called a synchronous opposite-direction sliding device, including a frame 8, a guide rail 9, and a locking block 13; the slider is disposed on the first slider 4 and the bottom of the second slider 5, and the first slider 4 and the second slider 5 are slidably mounted on the top of the guide rail 9 through the slider; the frame 8 is a hollow rectangular frame with an open top; two guide rails 9 are provided, and the two guide rails 9 are fixed in parallel on the front and rear sides of the top of the frame 8; wherein, the belt 1 and at least one pulley 2 are located inside the frame 8.
[0051] The specific working principle of the above-mentioned synchronous opposite sliding device is as follows: the belt 1 and the pulley 2 are fixed to the inside of the frame 8 through the connecting parts. The first slider 4 and the bottom of the second slider 5 are mounted on the guide rail 9 at the top of the frame 8 through the locking block 13. When the motor 10 drives the pulley 2 on one side to rotate, the first slider 4 and the second slider 5 slide on the guide rail 9 through the locking block 13 under the drive of the belt 1, and the two sliders can be made to face each other. When the belt 1 moves in the opposite direction, the first slider 4 and the second slider 5 separate.
[0052] Based on any of the above embodiments, such as Figure 3 As shown, a mounting base 11 is connected to one side of the frame 8 along its length. A pulley 2 is rotatably mounted inside the mounting base 11. One end of the belt 1 passes through the mounting base 11 and is connected to the pulley 2 for transmission. The motor 10 is mounted outside the mounting base 11, and the output end of the motor 10 passes through the interior of the mounting base 11 and is rotatably connected to the pulley 2 inside it.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
