Description

Technical Field

[0001] This application relates to the field of mechanical transmission device technology, specifically a conveyor chain tension adjustment device. Background Technology

[0002] Transmission roller chains are used as core transmission components in the yarn production process because of their outstanding characteristics such as excellent transmission efficiency, precise and uniform transmission ratio, and large transmission power.

[0003] In particular, double-row 1-inch roller chains have become a common choice for bottom belt conveyors in silk processing workshops. In actual production operations, the weight of materials carried by the storage tanks is considerable, and the number of daily turnovers is relatively frequent. Such heavy workloads and frequent start-stop operations place almost stringent requirements on the performance and reliability of the roller chains.

[0004] The chain has numerous links, is quite long, and is heavy. However, troublingly, it lacks a tensioning device in the middle. This structural flaw directly leads to frequent malfunctions during operation, such as chain stretching and deformation, chain skipping, and, more seriously, chain breakage. These malfunctions not only severely disrupt the smooth flow of production, forcing production to abruptly stop, but also easily induce product quality defects, causing an increase in the proportion of defective products. This inflicts a double blow on the company's production efficiency and product reputation.

[0005] In view of this, the development of a conveyor chain tension adjustment device is urgent and crucial. It is expected to effectively solve a series of problems caused by the lack of tension in the roller chain, greatly enhance the operational stability and reliability of the cigarette making line, ensure the continuous operation of production activities and the consistent quality of products, and provide a solid technical support and strong guarantee for the efficient and stable production operation of the cigarette making industry. Utility Model Content

[0006] The main objective of this application is to provide a conveyor chain tension adjustment device, which aims to solve the technical problem of the lack of automatic chain tensioning function in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A conveyor chain tensioning adjustment device includes a cylinder. A fixed seat is provided on the outer wall of the cylinder. Multiple sliding grooves are formed on the inner wall of the cylinder. A motor is mounted on the top wall of the cylinder. A lead screw is rotatably connected to the inner top wall of the cylinder via a bearing, and the top end of the lead screw is fixedly connected to the output end of the motor via a coupling. A connecting seat is threaded onto the outer wall of the lead screw. Multiple sliders are provided on the outer wall of the connecting seat and are slidably connected within the sliding grooves. A top seat is provided on the outer side of the bottom wall of the connecting seat via multiple connecting rods. A spring is provided on the bottom wall of the top seat. A base is provided on the bottom wall of the spring. A support rod is inserted into the base. A tensioning wheel is provided on the bottom wall of the support rod.

[0009] As a further improvement of this application, the number of sliders is at least two, and they are arranged at equal intervals on the outer wall of the connecting seat.

[0010] As a further improvement of this application, the outer ring of the bearing is fixedly connected to the inner wall of the cylinder through a bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw.

[0011] As a further improvement of this application, the base is interference-fitted to the outer wall of the support rod.

[0012] As a further improvement of this application, the support rod has a hollow structure, with the top end of the support rod passing through the spring and the top seat, and the bottom end of the outer wall of the lead screw extending into the support rod.

[0013] As a further improvement of this application, a position sensor is provided on the bottom wall of the connector.

[0014] The technical solution provided in this application may include the following beneficial effects:

[0015] The tension adjustment device of this application solves the problem of insufficient tension of the roller chain in the existing cigarette making line due to the lack of an intermediate tensioning device. Through the coordinated action of components such as motor, lead screw, and spring, it can accurately apply and maintain a constant tension on the chain, effectively avoiding chain stretching deformation, chain skipping and breakage caused by improper tension, greatly improving the operational stability and reliability of the chain, and ensuring the continuity of the production process.

[0016] Stable chain operation helps ensure the efficient operation of the silk production line, reduces equipment downtime caused by chain failure, and enables materials to be continuously and smoothly transported on the bottom belt conveyor of the storage tank, thereby improving the production efficiency of the entire silk production workshop.

[0017] By using position sensors to monitor the position changes of the tension wheel in real time, the tension force of the tension wheel can be accurately recorded, and the motor can be started in time to adjust it according to the stretching of the chain. This precise monitoring and control mechanism ensures that the tension force is always within the appropriate range, avoiding damage to the chain and equipment caused by excessive or insufficient tension force, further improving the safety and reliability of equipment operation, and also providing a data foundation for intelligent management of the equipment, making it easier for operators to monitor and optimize the equipment status in real time.
