Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printing material conveying mechanism that prevents deviation. Background Technology
[0002] During the 3D printing process, a 3D printing material conveying device is needed to transport the 3D printing material. It is usually set as a belt conveyor to transport the raw material of the 3D printing material. The raw material includes metal materials and polymer materials, and the shape is a regular square or cylindrical shape.
[0003] As disclosed in the patent with publication number CN222023545U, a 3D printing material conveying device for preventing deviation, the existing technology of 3D printing material conveying devices directly conveys materials through belts and lacks a structure to prevent deviation. Therefore, during use, 3D printing materials are prone to deviation during the conveying process, which may cause the 3D printing materials to tip over or fail to reach the designated position. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 3D printing material conveying mechanism that prevents deviation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A 3D printing material conveying mechanism to prevent deviation includes a support frame with a conveyor belt fixed to the top. Fixed frames are fixedly connected to the top of both sides of the support frame. A mounting frame is fixedly connected between the tops of the fixed frames. An auxiliary positioning component is fixedly connected to the mounting frame. Multiple sliding grooves are formed on the mounting frame, and sliders are movably connected within each groove. A bidirectional threaded rod is movably connected to the middle position of the mounting frame, and the bidirectional threaded rod is slidably connected to two sliders located in the middle position of the mounting frame. A power component for rotating the bidirectional threaded rod is provided on one side of the mounting frame. A fixed plate is fixedly connected between the multiple sliders along the length of the support frame. Pulleys are movably connected to both ends of the fixed plate, and a belt is wound around the pulleys.
[0007] As a further embodiment of this utility model, the auxiliary positioning component includes an electric push rod, which is fixed to the upper surface of the mounting frame by bolts. The extended end of the electric push rod passes through the mounting frame and is fixedly connected to a pressure frame.
[0008] As a further improvement of this utility model, the bottom of the pressure frame is provided with multiple grooves, and rollers are movably connected in each of the multiple grooves.
[0009] As a further embodiment of this utility model, a retaining ring is fixedly connected to the bottom end of the pulley, and a telescopic rod is fixedly connected to the upper surface of the mounting frame, with the extended end of the telescopic rod passing through the mounting frame and fixed to the pressure frame.
[0010] As a further embodiment of this utility model, the power assembly includes a motor, which is fixed to one side of the mounting bracket by bolts, and one end of the motor output shaft passes through the mounting bracket and is fixed to a bidirectional threaded rod.
[0011] As a further embodiment of this utility model, a baffle is fixedly connected to the bottom of the fixing plate, and the baffle is in contact with the inner side of the belt.
[0012] As a further embodiment of this utility model, guide rods are fixedly connected to both ends of the mounting bracket, and the slider is slidably connected to the guide rods.
[0013] As a further embodiment of this invention, the pressure frame is located above the conveyor belt.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. This utility model adjusts the distance between the two fixed plates to adjust the spacing between the belts on both sides, which can accommodate 3D printing materials of different widths within the distance range between the two fixed plates. It eliminates the need to replace the entire conveyor equipment for materials of different widths. It can also block and restrict the raw materials on the conveyor belt to prevent them from shifting and easily moving off the conveyor belt, thereby improving work efficiency.
[0016] 2. In this utility model, the electric push rod drives the pressure frame to move downward, so that the roller contacts the top of the material on the conveyor belt, which can directly apply pressure to the material and further prevent the raw material from shifting upward or sideways during the conveying process.
[0017] 3. In this utility model, if the raw material comes into contact with the belt, the belt rotates with the pulley, which reduces the frictional resistance between the material and the belt and reduces the wear on the surface of the raw material. On the other hand, the lateral thrust of the baffle can correct the slight deviation of the material in real time, further realizing the anti-deviation conveying and improving the stability of material conveying.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.
[0023] Reference Figures 1-3 A 3D printing material conveying mechanism to prevent deviation includes a support frame 1 with a conveyor belt 12 fixed to the top. The material is conveyed via the conveyor belt 12. Fixed frames 2 are bolted to the top of both sides of the support frame 1. A mounting frame 7 is bolted between the tops of the fixed frames 2. An auxiliary positioning component is bolted to the mounting frame 7. The auxiliary positioning component includes an electric push rod 6, which is bolted to the upper surface of the mounting frame 7. The extended end of the electric push rod 6 passes through the mounting frame 7 and is bolted to a pressure frame 13. The bottom of the 13 has multiple grooves 17, and each groove 17 is rotatably connected to a roller 18. The roller 18 can assist in conveying the material on the top of the conveyor belt 12. The upper surface of the mounting frame 7 is fixed with a telescopic rod 4 by bolts, and the extended end of the telescopic rod 4 passes through the mounting frame 7 and is fixed to the pressure frame 13. The pressure frame 13 is located above the conveyor belt 12. The electric push rod 6 extends to move the pressure frame 13 downward, so that the pressure frame 13 drives the roller 18 to contact the top of the material on the conveyor belt 12, further preventing the raw material from deviating during the conveying process.
[0024] It should be noted that the mounting frame 7 has multiple sliding grooves 3, and sliders 8 are slidably connected in each of the multiple sliding grooves 3. A bidirectional threaded rod 5 is rotatably connected to the middle position of the mounting frame 7, and the bidirectional threaded rod 5 is slidably connected to two sliders 8 located in the middle position of the mounting frame 7. A power assembly for driving the bidirectional threaded rod 5 to rotate is provided on one side of the mounting frame 7. The power assembly includes a motor, which is fixed to one side of the mounting frame 7 by bolts. One end of the motor output shaft passes through the mounting frame 7 and is fixed to the bidirectional threaded rod 5. The motor drives the bidirectional threaded rod 5 to rotate, causing the sliders 8 to move along the sliding grooves 3.
[0025] Specifically, a fixed plate 10 is bolted between multiple sliders 8 located along the length of the support frame 1. Both ends of the fixed plate 10 are rotatably connected to pulleys 14, and belts 11 are wound around the pulleys 14. The sliders 8 move along the slide groove 3, thereby causing the two fixed plates 10 to move towards each other or relative to each other, realizing the adjustment of the spacing between the belts 11 on both sides. A baffle 16 is bolted to the bottom of the fixed plate 10, and the baffle 16 contacts the inner side of the belt 11. The material is conveyed forward by the conveyor belt 12. The belts 11 on both sides form a flexible guide channel under the support of the baffle 16, which restricts the lateral displacement of the material. Both ends of the mounting frame 7 are bolted to guide rods 9, and the sliders 8 are slidably connected to the guide rods 9. The guide rods 9 can guide the sliders 8. A retaining ring 15 is bolted to the bottom of the pulley 14. The retaining ring 15 can restrict the position of the belt 11 and prevent the belt 11 from derailing during operation.
[0026] Working principle: When it is necessary to feed 3D printing raw materials:
[0027] Width adaptation adjustment: Start the motor, the motor drives the bidirectional threaded rod 5 to rotate, so that the slider 8 moves along the slide groove 3. At the same time, the guide rod 9 guides the slider 8, so that the two fixed plates 10 move, thereby realizing the adjustment of the distance between the two belts 11.
[0028] Material limiting conveying: The material is conveyed forward by the conveyor belt 12. The belts 11 on both sides form a flexible guide channel under the support of the baffle 16, which restricts the lateral displacement of the material. The electric push rod 6 is activated. The electric push rod 6 extends and moves the pressure frame 13 downward. The pressure frame 13 drives the roller 18 to contact the top of the material on the conveyor belt 12, further preventing the raw material from deviating during the conveying process.
[0029] If the material comes into contact with the belt 11, the belt 11 rotates with the pulley 14, reducing frictional resistance and correcting minor deviations in real time through the lateral thrust of the baffle 16, thereby further achieving anti-deviation conveying.
