Description

Technical Field

[0001] This utility model relates to the field of inner tube filling technology, and in particular to an automatic inner tube filling production device. Background Technology

[0002] An automatic inner tube filling production device is a device used to automatically fill powdered materials into an inner tube. Such devices are used in many industries, especially in fields that require high precision and high efficiency production, such as military, chemical and pharmaceutical industries.

[0003] Current automatic inner tube filling production equipment requires first limiting the inner tube, then filling it with powdery material, and finally using a clamping mechanism to compress the powdery material inside the inner tube. However, the clamping mechanism is usually an integrated structure, which cannot completely compress the powdery material in inner tubes of different diameters, resulting in poor adaptability. At the same time, the process of filling powdery material often generates a lot of dust, which is scattered into the surrounding environment, causing pollution. Therefore, designing an automatic inner tube filling production equipment is something we need to consider in order to address these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic inner tube filling production device. This device addresses the filling issue by incorporating a limiting mechanism that clamps inner tubes of different diameters and positions them at the center of the support platform, facilitating subsequent filling and compaction. It also includes a filling and compaction mechanism that uses a ring-shaped pressure block to prevent material scattering and environmental pollution. The ring-shaped pressure block can be replaced to ensure complete material compaction.

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

[0006] An automatic inner tube filling production device includes a worktable with two support legs fixedly connected to its lower end, a U-shaped connecting plate fixedly connected to its upper end, and a support platform fixedly connected to its upper end. A rectangular inner groove is formed at the upper end of the support platform. A limiting mechanism includes a motor mounted on the right side of the support platform. A bidirectional threaded rod is rotatably connected between the left and right inner walls of the rectangular inner groove. The right end of the bidirectional threaded rod penetrates the right inner wall of the rectangular inner groove and is fixedly connected to the output shaft of the motor. Slider blocks are threadedly connected to both threaded ends of the bidirectional threaded rod, and arc-shaped clamping plates are fixedly connected to the upper ends of both sliders. A filling and pressing mechanism is used to fill and press raw materials into the inner tube.

[0007] Preferably, both sliders are slidably connected to the inner wall of the rectangular inner groove, and the two threaded ends of the bidirectional threaded rod have opposite thread directions.

[0008] Preferably, the filling and pressing mechanism includes a hydraulic telescopic rod installed at the top of the U-shaped connecting plate, a circular mounting block is fixedly connected to the telescopic end of the hydraulic telescopic rod, an annular inner groove is opened on the side of the circular mounting block, two mounting ports are symmetrically opened at the bottom of the annular inner groove, and a discharge device is provided at the upper end of the U-shaped connecting plate.

[0009] Preferably, an annular pressure block is provided on the outer side of the circular mounting block, and two protrusions are symmetrically fixedly connected to the inner side of the annular pressure block, with both protrusions fitting into the annular inner groove.

[0010] Preferably, the discharge port of the discharge device is connected to a flexible hose, the other end of which passes through the circular mounting block and extends to the lower end of the circular mounting block, and the flexible hose is fixedly connected to the circular mounting block.

[0011] Preferably, the motor is a servo motor that can change its rotation direction.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. A limiting mechanism is set up. The motor drives two arc-shaped clamping plates to move towards each other, which can stably clamp the inner tube. Since the clamping surfaces of the two arc-shaped clamping plates are both arc surfaces, they can keep the inner tubes of different diameters at the center point of the upper part of the support platform, thereby ensuring the normal operation of subsequent filling and pressing operations.

[0014] 2. A filling and pressing mechanism is provided. The hydraulic telescopic rod can drive the round mounting block, the ring-shaped pressing block, and the discharge end of the hose to be inserted into the inner tube, thereby filling the inner tube with material and then pressing it. Because the ring-shaped pressing block fits into the inner tube, it can effectively prevent powdery materials from flying out of the inner tube and polluting the surrounding environment. At the same time, the ring-shaped pressing block of appropriate size can be selected for inner tubes of different diameters, thereby ensuring complete pressing of the material. It has good adaptability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 An automatic inner tube filling production device includes a workbench 1, two support legs 2 are fixedly connected to the lower end of the workbench 1, a U-shaped connecting plate 3 is fixedly connected to the upper end of the workbench 1, a support platform 4 is fixedly connected to the upper end of the workbench 1, and a rectangular inner groove 5 is opened at the upper end of the support platform 4.

[0023] The system also includes a limiting mechanism, which includes a motor 6 installed on the right side of the support platform 4. The motor 6 is a servo motor that can change the direction of rotation. A bidirectional threaded rod 7 is rotatably connected between the left and right inner walls of the rectangular inner groove 5. The two threaded ends of the bidirectional threaded rod 7 have opposite thread directions. The right end of the bidirectional threaded rod 7 passes through the right inner wall of the rectangular inner groove 5 and is fixedly connected to the output shaft of the motor 6. A slider 8 is threadedly connected to both threaded ends of the bidirectional threaded rod 7. Both sliders 8 are slidably connected to the inner wall of the rectangular inner groove 5. An arc-shaped clamp 9 is fixedly connected to the upper end of both sliders 8.

[0024] The system also includes a filling and pressing mechanism, which can fill and press raw materials into the inner tube. The filling and pressing mechanism includes a hydraulic telescopic rod 10 installed at the top of the U-shaped connecting plate 3. A circular mounting block 11 is fixedly connected to the telescopic end of the hydraulic telescopic rod 10. An annular inner groove 12 is formed on the side of the circular mounting block 11. Two mounting ports 13 are symmetrically formed at the bottom of the annular inner groove 12. An annular pressure block 14 is provided on the outer side of the circular mounting block 11. The lower end of the annular pressure block 14 is at the same horizontal plane as the lower end of the circular mounting block 11. The inner side of the annular pressure block 14 is symmetrically fixed... The fixed connection has two protrusions 15, both of which fit into the annular inner groove 12. There is friction at the fit between the two protrusions 15 and the annular inner groove 12, which can ensure the stable connection between the annular pressure block 14 and the circular mounting block 11. The upper end of the U-shaped connecting plate 3 is provided with a discharge device 16, which is filled with material. Automatic discharge can be achieved by controlling the discharge device 16. The discharge port of the discharge device 16 is connected to a flexible hose 17. The other end of the flexible hose 17 passes through the circular mounting block 11 and extends to the lower end of the circular mounting block 11. The flexible hose 17 is fixedly connected to the circular mounting block 11.

[0025] In this utility model, when in use, the inner tube to be filled is placed near the center of the upper end of the support platform 4, the motor 6 is started, and the bidirectional threaded rod 7 is rotated, which drives the two sliders 8 and the two arc-shaped clamping plates 9 to move towards each other. Since the clamping surfaces of the two arc-shaped clamping plates 9 are both arc surfaces, for inner tubes of different diameters, the two arc-shaped clamping plates 9 can clamp the inner tube and place it at the center point of the upper end of the support platform 4 during the process of moving towards each other, thereby ensuring that the subsequent filling and pressing operations can be carried out normally.

[0026] After the limit is completed, the hydraulic telescopic rod 10 is controlled to drive the circular mounting block 11, the annular pressure block 14, and the discharge end of the hose 17 to move down synchronously until the circular mounting block 11 is inserted into the inner tube. At this time, the outer side of the annular pressure block 14 is in contact with the inner wall of the inner tube. Then the discharge device 16 is started to fill the inner tube with powdery material through the hose 17. During the filling process, the contact between the annular pressure block 14 and the inner tube can effectively prevent the powdery material from flying out of the inner tube and polluting the surrounding environment. After the filling is completed, the hydraulic telescopic rod 10 is controlled again to drive the circular mounting block 11 and the annular pressure block 14 to move down synchronously. During the downward movement, the circular mounting block 11 and the annular pressure block 14 can press the material in the inner tube. After the pressing is completed, the circular mounting block 11 is controlled to move up, and then the limit on the inner tube is released, and the inner tube can be recycled.

[0027] It is worth mentioning that when it is necessary to fill inner tubes of different diameters, the annular pressure block 14 can be replaced. Rotate the current annular pressure block 14 so that the two protrusions 15 are aligned with the two mounting ports 13 in the vertical direction. Then, the annular pressure block 14 can be moved down and removed. Then, align the two protrusions 15 on the new annular pressure block 14 with the two mounting ports 13 and insert it. Then, rotate the new annular pressure block 14 90° clockwise to complete the installation. The whole installation process is convenient and quick. For inner tubes of different diameters, an annular pressure block 14 of appropriate size can be selected to ensure complete compression of the inner tube material. Its adaptability is good.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
