Description

Technical Field

[0001] The utility model relates to the technical field of chain pre-tensioning structures, in particular to a wire oven chain pre-tensioning structure. Background Art

[0002] A chain pretensioner is a device used to ensure that a chain maintains proper tension during operation. It plays a vital role in various mechanical equipment and industrial applications. Such a mechanism is typically installed at the beginning of a chain drive system, such as that found on bicycles, motorcycles, or industrial equipment. The chain pretensioner senses changes in chain tension and adjusts accordingly, ensuring proper chain operation and extending its service life. Chain pretensioners come in various types, including spring, hydraulic, and pneumatic. The spring type is the most common, utilizing the elasticity of the spring to adjust chain tension. Furthermore, chain tensioners specifically designed for drive and conveyor technology reliably maintain chain tension, extending service life, and feature automatic reset and compensation for chain leaching. A recent patent has been granted for a chain tensioner for vertical circulating seedling cultivation equipment. This mechanism not only maintains chain tension but also prevents collisions between adjacent seedling trays.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-Figure 3The utility model provides a technical solution: a wire drying oven chain pre-tensioning structure, including a base 1, a support frame 2 is fixedly installed on the base 1, the support frames 2 are fixedly connected by a support beam 6, a gear shaft 3 is movably installed between the support frames 2, a gear 4 is fixedly installed on the gear shaft 3, a chain 5 is movably installed on the gear 4, a drying box 7 is fixedly provided at the rear of the support frame 2, the chain 5 is movably installed in the drying box 7, and a chain pre-tensioning mechanism, a cleaning limit mechanism and a lubrication mechanism are provided in the drying box 7.

[0025] The chain pretensioning mechanism includes a limit rod 201, which is movably mounted on the support frame 2. A limit nut 202 and a limit nut 203 are movably mounted on the limit rod 201. The limit rod is fixedly mounted on a limit plate 204. The support frame 2 is provided with a plurality of limit slots 205. The gear shaft 3 is movably mounted in the limit slots 205. The gear shaft 3 is movably mounted in the limit slots 205. The limit plate 204 movably fits over the gear shaft 3, allowing the gear shaft 3 to rotate through the limit plate 204.

[0026] A connecting rod 207 is fixedly installed on the other side of the limit plate 204, and an adjusting spring 209 is installed on the connecting rod 207. The other end of the adjusting spring 209 is fixedly installed with a support plate 208. The middle part of the support plate 208 is fixedly installed with an adjusting threaded rod 206, and an adjusting nut 210 is movably installed on the adjusting threaded rod 206.

[0027] The adjusting spring 209 is sleeved on the connecting rod 207 . The adjusting spring 209 is located between the limiting plate 204 and the supporting plate 208 . The adjusting nut 210 is in close contact with the inner wall of the supporting frame 2 .

[0028] Before the equipment is started, the adjustment spring located between the limit plate 201 and the support plate 208 is first slightly compressed by screwing the adjustment nut 210, so that the gear shaft 3 is in a suitable position. At this time, the chain on the gear 4 is in a taut state, and the distance between the limit nut 1 202 and the limit nut 2 203 on the limit rod 201 is adjusted to leave a certain amount of movable space for the gear shaft 3 located in the limit groove 205. During the operation of the equipment, the chain 5 on the gear 4 is in a high-speed operation state. At this time, the reserved limit space can effectively prevent the chain from suddenly straightening during operation, causing the chain to break and affecting the operation of the equipment.

[0029] Example 2

[0030] See also Figure 4-Figure 5The utility model provides a technical solution: a wire oven chain pre-tensioning structure, a cleaning limit mechanism includes a cleaning mechanism 301, a cavity is opened inside the cleaning mechanism 301, a high-pressure nozzle 305 is fixedly installed inside the cleaning limit mechanism 301, a limiting gear 306 is fixedly installed at the front end of the high-pressure nozzle 305, a high-pressure air gun 307 is fixedly installed at the front end of the limiting gear 306, and a waste liquid bin 308 is provided below the limiting gear 306.

[0031] The lubricating mechanism 304 includes a lubricating oil nozzle 309 , which is fixedly mounted on an internal channel of the lubricating mechanism 304 .

[0032] When the equipment is in operation, the lubricating oil on the chain 5 may absorb debris or dust in the air, which will hinder the transmission of the material strip, increase the friction between the chain 5 and the gear 4, and produce abnormal noise and other problems, affecting the working efficiency of the equipment. Therefore, it is necessary to clean and lubricate it. When the chain passes through the cleaning mechanism 301, the high-pressure nozzle 305 located above the chain 5 is opened, spraying high-pressure water onto the chain 5 to clean it. At the same time, the limit gear 306 located in the cleaning mechanism 301 is engaged with the chain 5 to prevent the chain 5 from running off during operation, so that the chain 5 and the gear 4 are always engaged to prevent the chain 5 from running off and damaging the equipment. After the cleaning of the chain 5 is completed, the high-pressure air gun 307 on the chain 5 is opened to blow the moisture on the chain 5 dry. After the cleaning and drying of the chain 5 is completed, the chain 5 enters the lubrication mechanism 304, and the lubricating oil nozzle 309 is opened to drip lubricating oil onto the chain 5 to complete the lubrication.

[0033] Working principle:

[0034] Before the equipment is started, the adjustment spring located between the limit plate 201 and the support plate 208 is first slightly compressed by screwing the adjustment nut 210, so that the gear shaft 3 is in a suitable position. At this time, the chain on the gear 4 is in a taut state, and the distance between the limit nut 1 202 and the limit nut 2 203 on the limit rod 201 is adjusted to leave a certain amount of movable space for the gear shaft 3 located in the limit groove 205. During the operation of the equipment, the chain 5 on the gear 4 is in a high-speed operation state. At this time, the reserved limit space can effectively prevent the chain from suddenly straightening during operation, causing the chain to break and affecting the operation of the equipment.

[0035] When the chain passes through the cleaning mechanism 301, the high-pressure nozzle 305 located above the chain 5 opens and sprays high-pressure water onto the chain 5 to clean it. At the same time, the limit gear 306 located in the cleaning mechanism 301 engages with the chain 5 to prevent the chain 5 from deviating during operation, so that the chain 5 and the gear 4 always remain engaged to prevent the chain 5 from deviating and damaging the equipment. When the chain 5 is cleaned, the high-pressure air gun 307 located on the chain 5 is opened to blow away the moisture on the chain 5. When the cleaning and drying work of the chain 5 is completed, the chain 5 enters the lubrication mechanism 304, and the lubricating oil nozzle 309 is opened to drip lubricating oil onto the chain 5 to complete the lubrication.
