Description

Technical Field

[0001] The utility model relates to the technical field of baling machines, in particular to a baling machine belt anti-deviation mechanism and a baling machine. Background Art

[0002] The baler is an efficient and practical packaging equipment, which tightly wraps the strapping tape around the items to be packaged, and then uses special tightening and connection technology to firmly fix and seal the items. This equipment is widely used in many industries such as logistics, food, and chemicals. It can not only significantly improve packaging efficiency and reduce labor costs, but also ensure the safety of packaging and prevent items from being damaged or scattered during transportation and storage. It is an indispensable and important tool in modern industrial production.

[0003] The conveying device designed inside the baler plays a vital role. It is responsible for smoothly and accurately conveying the items to be packaged to the packaging area. In this process, the conveyor belt becomes a key component, carrying the items and moving steadily inside the baler. This belt not only has excellent wear resistance and durability, but also ensures that the items will not slip or deviate during the conveying process, thus ensuring the accuracy and efficiency of packaging.

[0004] There is a problem with the belt drive system of traditional balers: the connection between the belt and the drive spindle easily causes the belt to deviate during transmission. This deviation can cause the belt to slip on the drive spindle or even detach from the spindle, which brings additional maintenance burden to the staff and may affect production. This requires the installation of some anti-deviation mechanisms on the device. Although there are some anti-deviation mechanisms on the market, there are some problems in practical applications. Especially when squeezing the belt, these mechanisms often cause the middle part of the belt to bulge, affecting the smoothness of the transmission and may also accelerate the wear of the belt. In addition, these mechanisms have a limited range of adaptability and are difficult to adapt to belts of different sizes. Therefore, we need to develop a more effective anti-deviation technology that can correct the deviation of the belt without causing new deformation to the belt, while ensuring the smoothness of the transmission and being widely adaptable to belts of various sizes. Such technological innovation is crucial to improving the overall performance of the baler. Utility Model Content
