Description

Technical Field

[0001] This utility model relates to the field of suction end technology, specifically to a suction end structure for a suction machine. Background Technology

[0002] Material feeding machines are widely used in the raw material conveying industry for equipment such as injection molding machines and extruders. They are easy to install, simple to operate, have strong long-distance conveying capacity, stable production, and reliable operation. They are auxiliary equipment for achieving fully automated production. Material feeding machines are used for conveying raw materials in injection molding. They can automatically feed materials to the injection molding machine. When the material hopper of the plastic central feeding system is low on material, it will send a signal to the material feeding machine. The material feeding machine uses the principle of suction to convey plastic raw materials to the material hopper of the injection molding machine. When the material reaches a certain level, the material feeding machine will stop, and it can resume conveying when the material is insufficient.

[0003] For example, patent document CN 221070081 U discloses a material suction structure for a powder suction machine, including a mounting rod and a support block. The mounting rod has a matching groove, and the support block has a cavity and a slot, with the mounting rod and slot fitting together. A clamping mechanism is installed in the cavity of the support block, and the power output end of the clamping mechanism can enter the matching groove of the mounting rod to fix the mounting rod and the support block. A bracket is fixedly connected to the support block, and a reversing mechanism is rotatably mounted on the bracket. A suction cylinder is fixedly mounted on the reversing mechanism. An opening and closing mechanism is installed inside the suction cylinder, and a suction pipe is fixedly mounted on the suction cylinder. The inlet end of the suction pipe is located inside the suction cylinder and inside the opening and closing mechanism. The material suction structure for a powder suction machine provided by this utility model can not only suction materials, but also be easily installed and disassembled with the material suction machine. Furthermore, the shape of the inlet end of the material suction structure can be changed according to the actual shape and size of the material, making it highly practical.

[0004] However, when this structure is used as the suction end of a material feeder in actual applications, due to its structural limitations, the suction end can often only be disassembled and installed individually. This means that the equipment often needs to be stopped before the suction end can be replaced. Furthermore, the equipment cannot perform precise and stable positioning and tightening of the suction end, which cannot meet daily usage needs. Therefore, it is urgent to design a suction end structure for a material feeder to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a suction end structure for a material suction machine, so as to solve the problem mentioned in the background art that, due to the limitations of its own structure, the existing structure of the material suction end of the material suction machine can only be disassembled and assembled individually when it is used in actual material suction operation. As a result, the equipment often needs to be stopped to complete the disassembly and replacement of the suction end. At the same time, the equipment cannot perform precise and stable positioning and fastening of the suction end, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a suction end structure of a suction machine, including a mounting frame, with connecting side covers fixedly connected to both sides of the mounting frame, and a cover frame fixedly connected to one end of each connecting side cover, and a first mounting cover movably connected inside the cover frame;

[0007] The mounting frame includes a top frame and a bottom frame. The top of the mounting frame is fixedly connected to the top of the mounting frame, and the bottom of the mounting frame is fixedly connected to the bottom of the mounting frame. An air pump is installed inside the top frame and the bottom frame.

[0008] Preferably, the base frame and the air pump are provided with a shrinkage groove inside, and a compression airbag is provided inside the shrinkage groove.

[0009] Preferably, one end of the compression airbag is fixedly connected to a top arc plate, and the top arc plate is adapted to the first mounting cover.

[0010] Preferably, a connecting pull block is fixedly connected to one side of the first mounting cover, and a connecting pull block is fixedly connected to one end of the connecting pull block.

[0011] Preferably, both the upper and lower surfaces of the first and second mounting covers are provided with sealing pads.

[0012] Preferably, a shrink cover is fitted on one side of the cover frame, and the shrink cover has limit strip airbags arranged inside the upper and lower parts, with a limit push strip fixedly connected to one end of each limit strip airbag.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The suction head structure of this material feeder, through the installation frame, connecting side cover, cover bracket, first mounting cover, connecting pull block, second mounting cover, shrink cover, limiting strip airbag, and limiting push strip, allows for rapid switching between multiple suction heads within the installation frame. In actual use, the operator first inserts the desired suction head into the first mounting cover, and then pushes the first mounting cover from inside the cover bracket into the installation frame. This allows the material feeder to perform its suction operation within the installation frame via the first mounting cover. The second mounting cover, connected by a pull block on one side of the first mounting cover, enters the housing frame on the other side of the mounting frame via a connecting side cover. The suction end can then be replaced, cleaned, and maintained inside the housing frame, ensuring the suction machine can be maintained without stopping. Simultaneously, when the first and second mounting covers are switched back and forth inside the mounting frame, the two sets of limiting airbags and limiting push bars inside the shrink cover engage and securely fasten on both sides, ensuring more precise positioning of the suction end inside the mounting frame, demonstrating the practicality of the equipment design.

[0015] The suction end structure of this suction machine, through the inclusion of a top frame, base frame, air pump, shrinkage trough, compression airbag, top connecting arc plate, second mounting cover, and sealing pad, further enhances the overall performance of the equipment. During daily use, when switching between the suction end of the first mounting cover, connecting block, and second mounting cover inside the mounting frame, the air pump inside the top and base frames can be activated accordingly. Then, the compression airbag inside the shrinkage trough is inflated or deflated, allowing the top connecting arc plate at one end to adapt to the top and bottom of the mounting frame, and to securely fit with the sealing pads on the top and bottom of the first and second mounting covers. This ensures the tightness of the suction end inside the first and second mounting covers when used within the mounting frame, demonstrating the comprehensiveness of the equipment design.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A material suction end structure for a material suction machine includes a mounting frame 1. Connecting side covers 2 are fixedly connected to both sides of the mounting frame 1. A cover frame 3 is fixedly connected to one end of each connecting side cover 2. A first mounting cover 4 is movably connected inside the cover frame 3. A connecting pull block 11 is fixedly connected to one side of the first mounting cover 4, and a connecting pull block 11 is fixedly connected to one end of the connecting pull block 11. Adhesive pads 13 are provided on the upper and lower surfaces of both the first mounting cover 4 and the second mounting cover 12. A shrink cover 14 is fitted onto one side of the cover frame 3. Limiting strip airbags 15 are provided inside the shrink cover 14, with limiting push strips 16 fixedly connected to one end of each limiting strip airbag 15. Material suction is performed inside the mounting frame 1 via the first mounting cover 4. Meanwhile, the second mounting cover 12, connected to the connecting pull block 11 on one side of the first mounting cover 4, enters the cover frame 3 on the other side of the mounting frame 1, connected by the connecting side covers 2. The material suction end can then be disassembled, cleaned, and maintained inside the cover frame 3.

[0024] The top frame 5 and the bottom frame 6 are fixedly connected to the top of the mounting frame 1 and the bottom of the mounting frame 1. The top frame 5 and the bottom frame 6 are equipped with an air pump 7. The bottom frame 6 and the air pump 7 are equipped with a shrinkage groove 8. The shrinkage groove 8 is equipped with a compression airbag 9. One end of the compression airbag 9 is fixedly connected to a top connecting arc plate 10. The top connecting arc plate 10 is adapted to the first mounting cover 4. The air pump 7 inside the top frame 5 and the bottom frame 6 is activated to inflate and deflate the compression airbag 9 inside the shrinkage groove 8. This allows the top connecting arc plate 10 at one end to be adapted to the top and bottom of the mounting frame 1 and to be fitted and secured with the upper and lower sealing pads 13 of the first mounting cover 4 and the second mounting cover 12.

[0025] Working principle: During use, the operator first inserts the suction head to be used into the first mounting cover 4, and then pushes the first mounting cover 4 from inside the cover frame 3 into the mounting frame 1. The suction operation of the material feeder can then be performed inside the mounting frame 1 via the first mounting cover 4. At this time, the second mounting cover 12, connected to the pull block 11 on one side of the first mounting cover 4, enters the cover frame 3 on the other side of the mounting frame 1 via the connecting side cover 2. The suction head can then be replaced, cleaned, and maintained inside the cover frame 3, ensuring that the material feeder can be maintained and used without stopping the machine. Simultaneously, when the first mounting cover 4 and the second mounting cover 12 are switched back and forth inside the mounting frame 1, the two sets of limiting strips 15 and limiting airbags 15 inside the shrink cover 14... Push bar 16 is used to perform adaptive docking and top fixation on both sides, ensuring more accurate positioning of the suction end inside the mounting frame 1. During daily use, when the first mounting cover 4, connecting pull block 11 and second mounting cover 12 are used to switch the suction end inside the mounting frame 1, the air pump 7 inside the top frame 5 and bottom frame 6 can be started adaptively, and then the air-pressing airbag 9 inside the upper and lower shrinkage groove 8 is inflated and deflated, so that the top connecting arc plate 10 at one end can be adapted to the upper and lower parts of the mounting frame 1, and fit and fix with the upper and lower pressing pads 13 of the first mounting cover 4 and the second mounting cover 12, ensuring the tightness of the suction end inside the first mounting cover 4 and the second mounting cover 12 when used inside the mounting frame 1. The above is the entire working principle of this utility model.
