Technical Field

[0001] This utility model belongs to the technical field of screening mechanisms, specifically relating to a screening mechanism for a tarpaulin grinding machine. Background Technology

[0002] The screening mechanism for a tarpaulin grinder is a mechanical device used to screen materials during the grinding process. It is usually installed at the discharge end of the tarpaulin grinder to separate the ground materials according to particle size. The design and configuration of the screening mechanism for a tarpaulin grinder will vary depending on the specific grinding process and material characteristics, but its core purpose is to improve the efficiency and accuracy of material processing.

[0003] In existing technologies, most screening mechanisms are not sealed. When the operation is stopped and the feeding pipe is removed, finer materials in the screening bucket may float out of the bucket due to the lack of sealing, which may cause material waste. Therefore, a screening mechanism for a tarpaulin grinding machine is proposed. Utility Model Content

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] 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.

[0025] 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 or selective embodiment that excludes other embodiments.

[0026] Example 1

[0027] Reference Figures 1-7 This is the first embodiment of the present invention, which provides a screening mechanism for a tarpaulin grinding machine, comprising:

[0028] The system includes an operating box 101, a protective cover 102 threaded to the end of the operating box 101, a connecting pipe 103 communicating with the surface of the protective cover 102, a sealing assembly 104 disposed in the inner cavity of the connecting pipe 103, a collection groove 105 opened in the inner cavity of the operating box 101, a locking assembly 106 disposed in the inner wall of the protective cover 102, a screen frame 107 used in conjunction with the locking assembly 106, and a vibration motor 108 adapted to be installed on the surface of the operating box 101, with the output end of the vibration motor 108 fixedly installed with the screen frame 107.

[0029] Specifically, the sealing assembly 104 includes an installation groove 104a formed in the inner wall of the connecting pipe 103, a rotating shaft 104b mounted in the inner wall of the installation groove 104a via a bearing, and a baffle 104c fixedly mounted on the surface of the rotating shaft 104b. The sealing assembly 104 also includes a sealing strip 104d fixedly connected to the surface of the baffle 104c, and a limiting block 104e fixedly mounted inside the connecting pipe 103. The limiting block 104e is in contact with the sealing strip 104d.

[0030] Furthermore, the sealing assembly 104 also includes a fixed shaft 104f fixedly installed on the surface of the baffle 104c, a limiting rod 104g hinged to the surface of the fixed shaft 104f, a connecting spring 104h fixedly connected to the inner cavity of the limiting rod 104g, and a push rod 104i fixedly connected to the connecting spring 104h. The push rod 104i is hinged to the inner wall of the connecting pipe 103 through the connecting shaft 104j. The sealing strip 104d and the limiting block 104e are both made of rubber. The connecting spring 104h plays a resetting role for the push rod 104i.

[0031] It should be noted that the use of the vibrating motor 108 can screen materials that need to be screened. When the vibrating motor 108 is started, the screen frame 107 can vibrate according to the vibration frequency of the motor, thereby screening the materials in the screen frame 107.

[0032] The sealing component 104 can seal and block the opening of the connecting pipe 103 when the device is not in use or when the material needs to be replaced, thus preventing the material in the bucket from floating out when the feeding pipe is removed.

[0033] During use, a movable sealing barrier is formed inside the connecting pipe 103 by the baffle 104c on the rotating shaft 104b, the limiting rod 104g on the fixed shaft 104f, and the sealing strip 104d and limiting block 104e connected thereto. When the device is not in use or the material is changed, the connecting spring 104h pushes the push rod 104i, causing the baffle 104c to rotate to the sealing position, and the sealing strip 104d to come into close contact with the limiting block 104e, thereby sealing the opening of the connecting pipe 103 and preventing material leakage. At the same time, the vibration of the vibrating motor 108 screens the material through the screen frame 107, and the setting of the sealing assembly 104 ensures that the material will not float out from the connecting pipe 103 during the entire operation, ensuring the continuity of the screening operation and the cleanliness of the environment.

[0034] In summary, the sealing component 104 effectively seals the control box 101 and the connecting pipe 103, preventing material leakage during replacement or equipment downtime. This design not only improves material screening efficiency and operational convenience but also ensures a clean and safe working environment, greatly enhancing the practicality and reliability of the entire screening system and providing users with efficient, environmentally friendly, and safe material handling.

[0035] Example 2

[0036] Reference Figures 1-7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a locking assembly 106 that facilitates the disassembly of the screen frame 107.

[0037] Specifically, the engaging assembly 106 includes a fixing plate 106a, a connecting plate 106b fixedly mounted on the side surface of the fixing plate 106a, and a return spring 106c fixedly connected to the surface of the connecting plate 106b. The engaging assembly 106 also includes a push plate 106d fixedly connected to the return spring 106c, a locking block 106e fixedly mounted on the side surface of the push plate 106d, and a locking groove 106f opened in the inner wall of the operating box 101, wherein the locking groove 106f engages with the locking block 106e.

[0038] The locking component 106 allows the screen frame 107 to be removed and cleaned when different materials are used for screening, thus avoiding material confusion when using different materials.

[0039] During use, the fixed plate 106a and the connecting plate 106b provide structural support, and the return spring 106c provides elastic force, allowing the push plate 106d to push the locking block 106e into the locking groove 106f on the inner wall of the operating box 101 under the action of the spring force, thereby fixing the screen frame 107. When it is necessary to change materials or clean the screen frame 107, the connection between the locking block 106e and the locking groove 106f can be manually released, and the screen frame 107 can be easily removed using the rebound force of the return spring 106c, achieving quick replacement and cleaning, and effectively preventing the mixing of different materials.

[0040] In summary, the snap-fit ​​assembly 106 enables the quick disassembly and installation of the screen frame 107, making the cleaning and maintenance of the screening equipment more convenient. This design not only improves the equipment's adaptability to different materials and avoids the risk of material mixing, but also significantly improves the efficiency and safety of screening operations, bringing users more flexible, efficient and hygienic operation.
