Description

An automatic weighing, batching, and conveying transmission device Technical Field

[0001] This application relates to the field of chemical experimental apparatus, and in particular to an automatic weighing, batching, transporting, and transmission device. Background Technology

[0002] In chemical experiments, especially those requiring extremely high reaction precision, the batching system plays a crucial role, and the weighing operation of materials is indispensable in the batching system.

[0003] The existing weighing operation for materials usually involves manually placing the material-filled tube on the weighing platform, weighing it, and then manually transferring it. This manual operation is not only inconvenient for automated production line operations, but also wastes a lot of the time and energy of the experimental personnel, resulting in low efficiency. Summary of the Invention

[0004] The purpose of this application is to provide an automatic weighing, batching, and conveying transmission device, which aims to solve or improve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, this application provides the following solution: This application provides an automatic weighing, batching, and conveying transmission device, comprising:

[0006] Weighing device, equipped with a weighing platform;

[0007] The conveying guide rail has a weighing through hole on its bottom wall along the direction of gravity, and the weighing through hole is located above the weighing platform;

[0008] Multiple movable parts are slidably mounted on the conveying guide rail. Each movable part has an assembly through hole along the direction of gravity. The assembly through hole is used to place a material tube. When the material tube is located in the middle of the assembly through hole, there is a gap between the side wall of the assembly through hole and the side wall of the material tube. When the assembly through hole is located above the weighing through hole, the material tube can fall onto the weighing platform.

[0009] A driving mechanism is used to drive the moving part to slide forward or backward along the conveying guide rail. When the moving part slides forward, it can push the material tube to slide along the conveying guide rail.

[0010] Optionally, a groove is provided at one end of the assembly through hole, and the two sides of the groove are inclined toward the two side walls of the slide on the conveying guide rail with the center line of the slide on the conveying guide rail as the intersection point. The two side walls of the groove are used to abut against the side wall of the material tube.

[0011] Optionally, the conveying guide rail includes a conveying section and a weighing section connected to each other. The conveying section has an opening, and the weighing section is located at the opening. The weighing section has a weighing through hole. The bottom walls of the weighing section located on both sides of the weighing through hole have symmetrically shaped slopes. The two slopes are located on both sides of the weighing platform. The high end of the slope is on the same plane as the bottom wall of the conveying section, and the low end of the slope faces the weighing platform and is not higher than the top surface of the weighing platform. The distance between the low end of the slope and the edge of the weighing platform is less than the diameter of the material pipe.

[0012] Optionally, one end of the movable member is provided with a pair of first ear plates, and the other end of the movable member is provided with a second ear plate. The pair of first ear plates of the movable member are used to hinge with the second ear plate of another movable member.

[0014] Optionally, the annular belt is made of an elastic material.

[0015] Optionally, the moving component includes a restraining ring and a pair of side plates fixedly connected to the bottom surface of the restraining ring. The mounting through hole is opened in the restraining ring. The restraining ring rests on the top of the two side walls of the conveying guide rail. The side plate slides are fitted into the slides of the conveying guide rail.

[0016] Optionally, the conveying guide rail has a closed-loop structure.

[0017] Optionally, a support platform may also be included for assembling the weighing device, the conveying guide rail, and the drive mechanism.

[0018] Optionally, a lifting frame is provided between the conveying guide rail and the driving mechanism and the support platform.

[0019] This application discloses the following technical effects: By opening a weighing through hole on the conveying guide rail and an assembly through hole on the moving part, the material tube containing the material is simply placed into the assembly through hole. The moving part is driven by the drive mechanism to slide along the conveying guide rail. When the assembly through hole with the material tube is above the weighing through hole, the material tube can automatically fall onto the weighing platform. Through the backward sliding of the moving part, any contact object is removed from the side wall of the material tube, so that the weighing platform can weigh the material tube. After the weighing is completed, the material tube continues to slide along the conveying guide rail as driven by the drive mechanism. It can be combined with an external loading device. By simply placing a batch of material tubes into multiple assembly through holes, automatic weighing and transportation of materials can be realized. It can be adapted to automated production line applications, effectively reducing the workload of experimental personnel and improving experimental efficiency. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Referring to Figures 1-3, this application provides an automatic weighing, batching, and conveying transmission device, comprising:

[0028] Weighing device 1, equipped with weighing platform 11;

[0029] The conveying guide rail 2 has a weighing through hole 21 on its bottom wall along the direction of gravity, and the weighing through hole 21 is located above the weighing platform 11.

[0030] Multiple movable parts 3 are slidably mounted on the conveying guide rail 2. The movable parts 3 have assembly through holes 31 along the direction of gravity. The assembly through holes 31 are used to place the material tube 4. When the material tube 4 is located in the middle of the assembly through hole 31, there is a gap between the side wall of the assembly through hole 31 and the side wall of the material tube 4. When the assembly through hole 31 is located above the weighing through hole 21, the material tube 4 can fall onto the weighing platform 11.

[0031] The drive mechanism is used to drive the moving part 3 to slide forward or backward along the conveying guide rail 2. When the moving part 3 slides forward, it can push the material tube 4 to slide along the conveying guide rail 2.

[0032] By opening a weighing through hole 21 on the conveying guide rail 2 and an assembly through hole 31 on the moving part 3, the material tube 4 filled with material is placed into the assembly through hole 31. The moving part 3 is driven by the drive mechanism to slide along the conveying guide rail 2. When the assembly through hole 31 with the material tube 4 is above the weighing through hole 21, the material tube 4 can automatically fall onto the weighing platform 11. By sliding backward of the moving part 3, any contact object is removed from the side wall of the material tube 4, so that the weighing platform 11 can weigh the material tube 4. After the weighing is completed, the material tube 4 continues to slide along the conveying guide rail 2 as driven by the drive mechanism. It can be combined with an external loading device. By placing a batch of material tubes 4 into multiple assembly through holes 31, the automatic weighing and transportation of materials can be realized. It can be adapted to automated production line applications, effectively reducing the workload of experimental personnel and improving experimental efficiency.

[0033] In one embodiment of this application, a groove 32 is provided at one end of the assembly through hole 31. The two sides of the groove 32 are inclined toward the two side walls of the slide on the conveying guide rail 2 with the center line of the slide as the intersection point. The two side walls of the groove 32 are used to abut against the side wall of the material tube 4.

[0034] By setting a pair of grooves 32 with symmetrically inclined sidewalls, when the moving part 3 slides forward, the sidewalls of the grooves 32 contact the material tube 4, which can push the material tube 4 to move. In addition, the pair of sidewalls of the grooves 32 can also play a guiding role, so that the material tube 4 is located in the center of the conveying channel on the conveying guide rail 2, thereby avoiding interference between the material tube 4 and the sidewalls of the conveying guide rail 2 when pushing the material tube 4 to move, so that the moving part 3 can slide smoothly in the sliding area on the conveying guide rail 2.

[0035] In one embodiment of this application, the conveying guide rail 2 includes a conveying section 22 and a weighing section 23 that are connected to each other. The conveying section 22 has an opening, and the weighing section 23 is located at the opening. The weighing section 23 has a weighing through hole 21. The bottom walls of the weighing section 23 on both sides of the weighing through hole 21 are respectively provided with slopes 24. The two slopes 24 are respectively located on both sides of the weighing platform 11. The high end of the slope 24 is on the same plane as the bottom wall of the conveying section 22, and the low end of the slope 24 faces the weighing platform 11 and is not higher than the top surface of the weighing platform 11. The distance between the low end of the slope 24 and the edge of the weighing platform 11 is less than the diameter of the material pipe 4.

[0036] By setting the slope 24, a guiding transition can be achieved, ensuring that the material pipe 4 moves stably whether it enters or exits the weighing through hole 21.

[0037] In one embodiment of this application, a pair of first ear plates 33 are provided at one end of the movable member 3, and a second ear plate 34 is provided at the other end of the movable member 3. The pair of first ear plates 33 of the movable member 3 are used to hinge with the second ear plate 34 of another movable member 3.

[0038] By setting a pair of first ear plates 33 and second ear plates 34, multiple moving parts 3 can be hinged together to facilitate the weighing of batches of material tubes 4.

[0039] In one embodiment of this application, the drive mechanism includes a pair of annular belts 5, which are rotatably disposed on both sides of the moving member 3 via a motor 6. The outer surface of the annular belts 5 is used to abut against the side wall of the moving member 3, and the annular belts 5 are made of elastic material.

[0040] The motor 6 drives the gear to rotate, and the gear meshes with the tooth groove on the inner surface of the annular belt 5 to drive the annular belt 5 to rotate. The rotation of the pair of annular belts 5 generates friction with the moving part 3, thereby driving the moving part 3 to slide along the conveying guide rail 2.

[0041] In one embodiment of this application, the moving part 3 includes a restraining ring 35 and a pair of side plates 36 fixedly connected to the bottom surface of the restraining ring 35. The assembly through hole 31 is opened in the restraining ring 35. The restraining ring 35 rests on the top of the two side walls of the conveying guide rail 2. The side plates 36 slide in the slide of the conveying guide rail 2.

[0042] The restraint ring 35 is used to contact the annular belt 5, and the side plate 36 is used to improve the stability between the belt and the conveyor rail 2.

[0043] In one embodiment of this application, the conveying guide rail 2 is a closed-loop structure.

[0044] The closed-loop conveyor rail 2 works in conjunction with multiple moving parts 3 to continuously weigh batches of materials through the material tube 4.

[0045] In one embodiment of this application, a support platform 7 is also included for assembling the weighing device 1, the conveying guide rail 2, and the drive mechanism.

[0046] In one embodiment of this application, a lifting frame 8 is provided between the conveying guide rail 2 and the drive mechanism and the support platform 7.

[0047] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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 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] The embodiments described above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made to the technical solutions of this application by those skilled in the art without departing from the spirit of this application shall fall within the protection scope defined by the claims of this application.
