Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machines, in particular to a lifting structure of a rubber mixing machine. Background Art

[0002] Rubber mixers are divided into two categories: open type and closed type. They are traditional equipment widely used in the rubber and plastic processing industry. Open type machines are mainly used for rubber hot refining, tableting, rubber breaking, plastic refining and mixing. Open type rubber mixers have been used in production since 1826. Their structure is relatively simple and they are still widely used today. The open design means that the material is not processed in a closed cavity, but is directly exposed to the operator, making it easier to observe and control the mixing process.

[0003] However, the traditional rubber mixer does not have a lifting structure platform, which leads to many inconveniences in use. For example, before or after the rubber mixing, it is difficult to load and unload materials and there is no place to store them. In addition, in the case of maintenance or emergency shutdown, the drum area is directly exposed to the outside, which is easy to cause accidental contact and injury. Therefore, it is necessary to design a lifting structure suitable for open rubber mixers. Utility Model Content

[0004] The utility model aims to provide a lifting structure of a rubber mixing machine to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a lifting structure of a rubber mixer, comprising a bottom plate, which is used to support the lifting structure of the rubber mixer, including:

[0007] A pusher, which is arranged on the bottom plate and is used to push the platform;

[0008] The platform is arranged on the support structure and the pusher and is used to carry the rubber mixing machine;

[0009] A protective structure is arranged on the bottom plate and is used to protect the platform.

[0010] Preferably, a protective fence is provided on the bottom plate.

[0011] Preferably, the support structure includes a sliding rod unit arranged on the bottom plate, a fulcrum unit arranged on the bottom plate and the sliding rod unit, and a supporting rod unit arranged on the fulcrum unit.

[0012] Preferably, the slide bar unit includes a bearing plate arranged on the bottom plate, and a bearing slide bar arranged on the bearing plate for bearing the fulcrum unit.

[0013] Preferably, the fulcrum unit includes a fixed block arranged on the base plate, a sliding sleeve arranged on the bearing slide rod, a fixed plate arranged on the fixed block and the sliding sleeve, and a connecting shaft arranged on the fixed plate.

[0014] Preferably, the support rod unit includes a bracket arranged on the connecting shaft, and a fixed shaft arranged on the bracket for connecting with other brackets.

[0015] Preferably, a base is provided on the pusher for adjusting the pushing direction of the pusher.

[0016] Preferably, the platform includes a platform fence arranged on the platform, and a connecting plate arranged on the platform.

[0017] Preferably, the protective structure comprises a frame unit, and a slide unit arranged on the frame unit;

[0018] The frame unit includes an end plate arranged on the bottom plate, an outer side plate arranged on the end plate, and a longitudinal sliding rod arranged on the end plate;

[0019] The slide plate unit comprises a lifting frame arranged on the connecting plate for holding the connecting plate, a slide plate arranged on the lifting frame, and a spring arranged on the slide plate.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows: the lifting structure of the rubber mixer pushes the platform through the pusher and uses the bracket structure to support the platform. In the event of an accident, it also has a protective structure to protect the platform, which effectively increases the lifting function of the platform, improves the operability of the platform, and is more convenient in actual use; before or after the start of rubber mixing, the lifting platform can be lowered, making the loading and unloading of materials more convenient.
