[0004] In the field of conveyors, existing technologies can tension belts through the cooperation of components such as fixed frames. However, in actual use, multiple bolts and nuts need to be manually operated and adjusted, which cannot achieve the effect of automation and makes the overall use quite troublesome.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technologies require manual operation and adjustment of multiple bolts and nuts, they cannot achieve automation and make the overall use quite cumbersome.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Please see Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a conveyor tensioning device, including: a mounting frame 1, a conveyor belt 2 slidably connected inside the mounting frame 1, a mounting shell 3 embedded at the bottom end of the mounting frame 1, and an adjustment mechanism 4 provided inside the mounting shell 3;

[0032] The adjustment mechanism 4 includes a servo motor 401, which is embedded in the outer wall of the mounting housing 3. A bidirectional threaded rod 402 is fixedly installed at the power output end of the servo motor 401. A sliding frame 403 is slidably connected to the outer wall of the bidirectional threaded rod 402. A fixing plate 404 is fixedly installed at the top of the sliding frame 403. A support shaft 405 is rotatably connected to one end of the fixing plate 404. A support frame 406 is fixedly installed at both ends of the support shaft 405. An abutment roller 407 is rotatably connected to the top of the support frame 406.

[0033] Specifically, telescopic rods 409 are fixedly installed on both sides of the bottom end of the support frame 406, and a fixing sleeve 408 is sleeved on the bottom end of the telescopic rods 409.

[0034] Furthermore, the telescopic structure formed by the fixed sleeve 408 and the telescopic rod 409 can limit the support frame 406 and prevent it from being affected and causing lateral displacement or offset.

[0035] Specifically, the bidirectional threaded rod 402 is threadedly connected to the sliding frame 403, and the sliding frame 403 and the mounting shell 3 form a sliding structure.

[0036] Furthermore, through the threaded connection between the bidirectional threaded rod 402 and the sliding frame 403, the two sliding frames 403 can slide relative to each other or away from each other under the drive of a servo motor 401, thus maintaining the balance of the support frame 406.

[0037] Specifically, the fixed plate 404 and the support shaft 405 form a rotating structure, and the fixed plate 404 and the support frame 406 form a rotating structure.

[0038] Furthermore, a rotating structure is formed between the fixed plate 404, the support shaft 405, and the carrier frame 406, which enables the fixed plate 404 to rotate adaptively during displacement and allows the carrier frame 406 to allow the contact roller 407 to contact the conveyor belt 2 for tensioning.

[0039] Specifically, a support frame 5 is fixedly installed inside the mounting frame 1, and a support roller 6 is rotatably connected inside the support frame 5.

[0040] Furthermore, the support frame 5 and the support roller 6 can support the conveyor belt 2 from below, thus providing a certain load-bearing effect on the materials being conveyed.

[0041] In use, the conveyor consists of multiple parts, including the mounting frame 1, conveyor belt 2, power system, control system, and sensing system. This is existing technology and will not be described in detail here. A tension sensor is installed on the outer wall of the roller that supports the conveyor belt 2 to monitor the tension of the conveyor belt 2 in real time. When a problem occurs in the data, the servo motor 401 is started by the control system and signal, which pushes the sliding frame 403 to rotate via the bidirectional threaded rod 402. This causes the fixed plate 404 to rotate and resist through the cooperation of the support shaft 405, allowing the support frame 406 to change its angle and be adjusted upwards. The contact roller 407 then contacts the conveyor belt 2 to prevent it from loosening. When the tension sensor detects normal data, the servo motor 401 is stopped by the control system and signal in time, achieving an automation effect.

[0042] In summary, by operating the servo motor 401, the contact roller 407 can adjust the contact and pressing of the conveyor belt 2, thereby automatically adjusting the tension. This avoids manual disassembly or the use of multiple bolts and nuts for adjustment, making the tension adjustment automated and improving the convenience and efficiency of the entire device.

[0043] Example 2

[0044] Please see Figure 3 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a conveyor tensioning device.

[0045] Specifically, a connecting plate 7 is fixedly installed at the front end of the support frame 406, and a cleaning mechanism 8 is provided on one side of the connecting plate 7.

[0046] Furthermore, the cleaning mechanism 8 can be positioned on one side of the contact roller 407 by the fixing and support of the connecting plate 7, making it convenient to contact the conveyor belt 2.

[0047] Specifically, the cleaning mechanism 8 includes a triangular block 801, which is fixedly installed on one side of the connecting plate 7, and a through rod 802 protrudes from the inside of the triangular block 801.

[0048] Furthermore, the triangular block 801 allows the through rod 802 to slide stably and be perpendicular to the conveyor belt 2.

[0049] Specifically, a contact block 803 is fixedly installed at the top of the protruding rod 802, a spring 804 is fixedly installed at the bottom of the contact block 803 protruding from the outside of the rod 802, and a scraper 805 is fixedly installed at the top of the contact block 803.

[0050] Furthermore, the elastic push of the spring 804 allows the scraper 805 fixed by the contact block 803 to contact one side of the conveyor belt 2, which can effectively clean the dust and other particles adsorbed by the conveyor belt 2 during the conveying process.

[0051] In use, with the connecting plate 7 fixed, the through rod 802 connected to the triangular block 801 can be slidably connected to the conveyor belt 2 and perpendicular to the conveyor belt 2. The scraping plate 805 is brought close to the conveyor belt 2 by the contact block 803 and is put into contact under the elastic push of the spring 804, thereby scraping off the adsorbed dust and impurities to achieve a cleaning effect. Later, the scraped dust and impurities can be collected and counted by equipment such as vacuum cleaners.

[0052] In summary, the scraper plate 805 can effectively clean the dust and impurities adsorbed on the outer wall of the conveyor belt 2 during the conveying process, preventing dust and other impurities from adsorbing on the conveyed material due to the continuous operation of the conveyor belt 2. This automatic cleaning function further improves the automation and functionality of the entire equipment.
