Description

Technical Field

[0001] This utility model relates to the field of belt scale conveyors, and in particular to a belt scale conveyor for cement production. Background Technology

[0002] Belt conveyors are crucial equipment in cement production lines. They not only transport materials but also monitor and control their weight in real time to ensure production accuracy. Belt conveyors measure material weight by installing load cells on the conveyor belt. As material passes through the weighing area, the sensors detect pressure changes caused by the material's weight and convert these changes into electrical signals, which are then sent to the control system. The control system calculates the material's weight based on these signals and makes appropriate adjustments.

[0003] Existing belt conveyors utilize conveyor belts for weighing and transporting cement materials. However, these conveyors lack a scraping mechanism, allowing material to easily adhere to the conveyor belt, affecting accurate weighing and transport, and causing material waste. In some belt conveyors with scraping mechanisms, the scraper is fixedly installed. Excessive contact force between the scraper and the conveyor belt can disrupt normal operation, while insufficient contact force can lead to incomplete scraping, resulting in mediocre performance.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a belt scale conveyor for cement production includes a conveyor frame 1, a conveyor roller 2 mounted on the conveyor frame 1, a conveyor belt 3 fitted onto the conveyor roller 2, a reduction motor 4 mounted on the conveyor frame 1, a scraper structure 5 installed at the end of the conveyor frame 1, support legs 6 fixed to the lower surface of the conveyor frame 1, and a correction roller 7 mounted on the conveyor frame 1, which contacts the conveyor belt 3. An adjusting frame 9 is provided at the end of the conveyor frame 1, and the conveyor roller 2 located at one end of the inner side of the conveyor frame 1 is connected to the adjusting frame 9. A weighing sensor 8 is mounted on the conveyor frame 1, and a weighing roller is mounted on the weighing sensor 8.

[0020] In cement production, a belt conveyor is used for the quantitative transport of relevant materials. During operation, the belt conveyor is stably positioned using support legs 6, and the tension of the conveyor belt 3 on the conveyor frame 1 is adjusted using an adjusting frame 9. The scraping structure 5 is adjusted according to actual conditions, and then the belt conveyor is used for material transport. During the feeding process, material is fed onto the conveyor belt 3, and the reduction motor 4 starts, rotating the conveyor roller 2, thereby moving the conveyor belt 3. The material is transported using the conveyor belt 3. When the material reaches the weighing sensor 8, the weighing sensor 8 weighs it and provides feedback data. Based on the weighing data, the material feeding amount is adjusted, achieving precise feeding. During the feeding process, material is fed from the end of the conveyor belt 3. During this process, the scraping structure 5 scrapes the conveyor belt 3 to prevent material from adhering to it.

[0021] According to the above implementation scheme, the scraping structure 5 includes a mounting frame 501, a connecting plate 502, a fixing frame 503, an elastic connecting component 504, and a scraper 505. The mounting frame 501 is connected to the connecting plate 502, the fixing frame 503 is mounted on the mounting frame 501, and the scraper 505 is mounted on the mounting frame 501 through the elastic connecting component 504. The scraping structure 5 also includes a connecting rod 506. The connecting plate 502 is fixed to the end of the conveying frame 1 by screws, the fixing frame 503 is fixed to the mounting frame 501 by mounting bolts, and the connecting rod 506 is connected to the lower end of the elastic connecting component 504.

[0022] The elastic connection assembly 504 includes a movable rod 5041, a stop block 5042, an adjusting rod 5043, a circular plate 5044, a clamping screw 5045, and a spring 5046. The movable rod 5041 is fixedly connected to the stop block 5042, and a stud is provided at the upper end of the movable rod 5041. The movable rod 5041 is fixedly connected to the scraper 505 through the stud. The movable rod 5041 passes through the fixed frame 503. Adjusting rod 5043 is fixedly connected to circular plate 5044, and circular plate 5044 is sleeved on movable rod 5041. Adjusting rod 5043 passes through fixed frame 503, and the lower end of circular plate 5044 is fixed together with connecting rod 506. Tightening screw 5045 is threadedly connected to fixed frame 503, and the end of tightening screw 5045 abuts against adjusting rod 5043. Spring 5046 is sleeved on movable rod 5041, and spring 5046 is located between circular plate 5044 and scraper 505.

[0023] When installing the scraper structure 5, the mounting frame 501 is fixed to the conveyor frame 1 by the connecting plate 502 and screws, and the fixing frame 503 is set on the mounting frame 501 by mounting bolts. At this time, the lower end of the elastic connecting component 504 is connected to the fixing frame 503, and the upper end is connected to the scraper 505. The relative height of the scraper 505 is adjusted according to the actual situation. During adjustment, after loosening all the clamping screws 5045, the adjusting rod 5043 is raised and lowered by the connecting rod 506. The adjusting rod 5043 moves the circular plate 5044. Since the elasticity of the spring 5046 remains unchanged, the scraper 505 moves through the movable rod 5041 under the drive of the spring 5046, thereby changing the height of the scraper 505. After the adjustment is completed, the adjusting rod 5043 is fixed by the clamping screws 5045. During the feeding process, the scraper 505 contacts the conveyor belt 3 to scrape the material. Due to the action of the spring 5046, the scraper 505 and the conveyor belt 3 are in elastic contact, which can ensure the scraping effect and avoid causing the conveyor belt 3 to jam. The structure is simple and the performance is excellent.

[0024] It should be noted that, through the scraping structure 5, the material can be scraped at the end of the conveyor belt 3 during the conveying of cement materials, ensuring that the material can fall completely and preventing the material from adhering to the conveyor belt 3, thus ensuring the accuracy of weighing and conveying, and avoiding waste. The scraper 505 is installed using the elastic connecting component 504. During the scraping process, the scraper 505 can operate flexibly through the elastic connecting component 504, avoiding excessive contact force between the scraper 505 and the conveyor belt 3, which could cause the conveyor belt 3 to jam, while ensuring thorough scraping. The adjusting rod 5043 and the circular plate 5044 in the elastic connecting component 504 can be adjusted in position, thereby changing the relative position of the scraper 505, improving the flexibility and adaptability of use. The connecting rod 506 is located at the lower end of the adjusting rod 5043, ensuring that all adjusting rods 5043 are adjusted synchronously, resulting in good performance.

[0025] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
