Description

Technical Field

[0001] This utility model relates to the field of vibrating screen installation technology, specifically a quick fixing device for vibrating screen pressure bars. Background Technology

[0002] The design of a quick-fixing device for the vibrating screen pressure bar usually needs to take into account the high-frequency vibration and impact force during the operation of the vibrating screen, as well as the operator's need for high efficiency in installation and disassembly.

[0003] First, if the pressure strip cannot be fixed quickly, the installation and disassembly process will become cumbersome, increasing equipment downtime and affecting production efficiency.

[0004] Secondly, without the hammering function, the material on the screen may accumulate and stick to the screen, causing screen blockage and thus reducing screening efficiency and accuracy.

[0005] Finally, without the function of adjusting the force, the hammering force remains constant, which may lead to unsatisfactory cleaning results for different materials. In particular, for more fragile or easily damaged screens, excessive hammering may damage the screen. Utility Model Content

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5A quick-fixing device for a vibrating screen pressure bar includes a main body 1, an installation mechanism, and an adjustment assembly. The installation mechanism includes a screen 2, an installation bar 3, a support frame 4, a fixing member 5, and a threaded sleeve 6. The screen 2 is installed inside the main body 1 and fixedly connected to the installation bar 3. The installation bar 3 is installed inside the main body 1 and mates with the main body 1. The support frame 4 is installed inside the main body 1 and mates with the main body 1. The fixing member 5 is installed inside the main body 1 and contacts the support frame 4. The threaded sleeve 6 is installed on the main body 1 and threadedly engages with the main body 1. The adjustment assembly includes a spring 7, a pushing member 8, and a connecting member 9. The spring 7 is installed on the pushing frame, and its other end is fixedly connected to the fixing member 5. The pushing member 8 is installed in the fixing member 5 and slidably connected to the fixing frame. The connecting member 9 is installed in the pushing member 8 and threadedly engages with the fixing member 5 and rotatably connects with the pushing member 8.

[0031] In this embodiment, the installation mechanism includes a screen 2, an installation strip 3, a support frame 4, a fixing member 5, and a threaded sleeve 6. In use, the screen 2 is first installed into the main body 1. At the same time, the installation strip 3, which is fixedly connected to the screen 2, also enters the main body 1, and the magnetic strip 11 on the installation strip 3 enters the installation groove 10 inside the main body 1. At this time, the screen 2 is fixed inside the main body 1. Then, the support frame 4 is installed into the main body 1, and the pressure strip 12 on the support frame 4 contacts the screen 2. After the support frame 4 is installed, the fixing frame is placed in place. After the fixing frame contacts the support frame 4, the threaded sleeve 6 is installed to the bottom of the main body 1. At this time, after the threaded sleeve 6 contacts the fixing frame, the wrapping edge 22 on the threaded sleeve 6 also contacts the edge of the main body 1, thereby effectively preventing external dust from entering the connection between the threaded sleeve 6 and the main body 1, and facilitating the removal of the threaded sleeve 6 from the main body 1.

[0032] In this embodiment, the adjustment assembly includes a spring 7, an actuating member 8, and a connecting member 9. After the main body 1 is installed, the position of the actuating member 8 needs to be adjusted so that the contact block 21 on the actuating member 8 and the screen 2 are kept in contact without damaging the screen 2, allowing the material attached to the screen 2 to be hammered and thrown up. At this time, the connecting member 9 is rotated so that the external thread 19 on the connecting member 9 engages with the internal thread 16 in the sliding tube 14, thereby allowing the limiting block 18 on the connecting member 9 to be positioned within the actuating member 8. The top actuator 8 slides in the limiting groove 17 and presses against the limiting groove 17, causing the position of the top actuator 8 to rise. After the position of the top actuator 8 rises, the spring 7 is compressed and the stroke of the spring 7 is reduced. When the main body 1 is installed on the machine and vibrates, the top actuator 8 can slide on the sliding tube 14, and the position prevents the contact block 21 on the top actuator 8 from shifting. At this time, the positioning block 20 on the top actuator 8 slides in the positioning groove 15 of the sliding tube 14 installed on the reinforcing plate 13, and vibrates the screen 2.

[0033] Example 2:

[0034] In summary, during use, first assemble the main body 1. Then, install the screen 2 inside the main body 1. The mounting strip 3, which is fixedly connected to the screen 2, also enters the main body 1, and the magnetic strip 11 on the mounting strip 3 enters the mounting groove 10 inside the main body 1. At this point, the screen 2 is fixed inside the main body 1. Next, install the support frame 4 inside the main body 1. The pressure strip 12 on the support frame 4 contacts the screen 2. After the support frame 4 is installed, place the fixing frame in place. After the fixing frame contacts the support frame 4, install the threaded sleeve 6 to the bottom of the main body 1. When the threaded sleeve 6 contacts the fixing frame, the webbing edge 22 on the threaded sleeve 6 also contacts the edge of the main body 1, thus effectively preventing external dust from entering the connection between the threaded sleeve 6 and the main body 1, facilitating the removal and removal of the threaded sleeve 6 from the main body 1. After the main body 1 is assembled, the position of the top moving part 8 needs to be adjusted. The contact block 21 on the top actuator 8 is kept in contact with the screen 2 without damaging the screen 2, allowing the material attached to the screen 2 to be hammered and thrown up. At this time, the connecting part 9 is rotated so that the external thread 19 on the connecting part 9 engages with the internal thread 16 in the sliding tube 14, so that the limiting block 18 on the connecting part 9 can slide in the limiting groove 17 of the top actuator 8 and press against the limiting groove 17, causing the position of the top actuator 8 to rise. After the position of the top actuator 8 rises, the spring 7 is compressed and the stroke of the spring 7 is reduced, so that when the main body 1 is installed on the machine and vibrates, the top actuator 8 can slide on the sliding tube 14, and the position prevents the contact block 21 on the top actuator 8 from shifting. At this time, the positioning block 20 on the top actuator 8 slides in the positioning groove 15 of the sliding tube 14 installed on the reinforcing plate 13, and vibrates the screen 2.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
