Description

Technical Field

[0001] The utility model relates to the technical field of rubber liners, in particular to a composite rubber liner for an enhanced ball mill. Background Technique

[0002] Rubber liners have the advantages of low energy consumption, high wear resistance / impact resistance, low noise, easy installation, corrosion resistance, saving media (steel balls), and long service life. The use of rubber materials and metal composite lifting bars has gradually replaced the traditional lifting bars cast from manganese steel and alloy steel. Metal is used to bear the frictional force, and rubber is used to bear the impact force.

[0003] At present, alloy bars are generally fixed on the lifting surface of rubber blocks, and the two are fixedly bonded through an adhesive. For example, a rubber liner lifting bar for a ball mill disclosed in the Chinese patent publication number "CN102921513A". In order to enhance its elasticity and impact absorption ability, some composite rubber liners are also provided with strengthening structures, such as the impact-resistant rubber liner disclosed in the Chinese publication number "CN202179987U".

[0004] Considering that the traditional strengthening structure is relatively simple and the enhanced effect on the liner is limited during the actual operation process, therefore, in order to further optimize the durability and applicability of the existing composite rubber liner, we propose a composite rubber liner for an enhanced ball mill.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-3 An embodiment of the present utility model discloses a composite rubber lining plate for an enhanced ball mill. The rubber lining plate includes a rubber part 1, and an alloy part 2 is fixed on the lifting surface of the rubber part 1. That is, in this embodiment, the composite method of rubber and alloy is adopted to optimize the friction resistance and impact resistance of the traditional rubber lining plate.

[0023] Wherein, a reinforcing part 3 is formed inside the rubber part 1, a skeleton 4 is embedded on the lower side of the rubber part 1, and a connecting part 5 is further arranged between the skeleton 4 and the reinforcing part 3.

[0024] In some embodiments, the reinforcing part 3 in the present utility model includes two first arms 31 that are mirror-symmetrical. The first arms 31 are arc-shaped structures and the arc centers are opposite.

[0025] Two second arms 32 are also connected between the two first arms 31.

[0026] Furthermore, on the basis of the above embodiments, the two second arms 32 are mirror-symmetrical. The second arms 32 are arc-shaped structures and the arc centers are opposite. Among them, the mirror axis of the second arm 32 is perpendicular to the mirror axis of the first arm 31.

[0027] Specifically, that is, in this embodiment, the combination of two first arms 31 and two second arms 32 is adopted to form a reinforcing frame structure, and in the length direction, it extends along this cross-sectional structure to support the inside of the rubber part 1, so that the whole lining plate has good elasticity and impact absorption ability. Preferably, the reinforcing part 3 in this embodiment is made of polyester fiber and rubber. In addition, cover plates can be arranged at both ends of the reinforcing part 3 to prevent the molten glue from entering its interior during injection molding, so as to ensure its internal hollow state and ensure the impact absorption ability.

[0028] In some embodiments, a limiting interval 33 is formed between one second arm 32 and the two first arms 31. At least part of the connecting part 5 is blocked in the limiting interval 33. Since both the second arm 32 and the first arm 31 are arranged in an arc-shaped structure, the limiting interval 33 is generally formed in an elliptical structure with an opening. The opening is used for inserting the connecting part 5, and the upper elliptical structure limits the connecting part 5.

[0029] Based on the above embodiments, in this embodiment, the connecting member 5 includes a stop end 51 and a rod end 52 connected to the stop end 51. The stop end 51 slides in the reinforcing member 3. A threaded portion 53 is provided at the bottom of the rod end 52, and the threaded portion 53 is threadedly connected to the skeleton 4.

[0030] Specifically, in this embodiment, the stop end 51 slides in the above-mentioned limiting interval 33, and the rod end 52 slides in the above-mentioned opening. Specifically, the connecting member 5 in this embodiment can be set as a metal part, such as stainless steel, etc.

[0031] During specific connection, before injection molding, the limiting interval 33 on the lower side of the above-mentioned reinforcing member 3 can be inserted along the stop ends 51 of multiple connecting members 5 first, so as to realize the connection and positioning of the reinforcing member 3 to ensure the stability of its position during the injection molding process. Secondly, after connecting the reinforcing member 3 and the skeleton 4 with the connecting member 5, the force transmission between the reinforcing member 3 and the skeleton 4 can also be realized, so as to ensure that both the reinforcing member 3 and the skeleton 4 can obtain better force transmission, thereby achieving a better anti-impact effect.

[0032] Furthermore, in this embodiment, a plurality of reinforcing sleeves 41 are fixedly arranged at intervals on the end face of the skeleton 4. The reinforcing sleeves 41 are located outside the threaded holes where the skeleton 4 is connected to the threaded portion 53. The reinforcing sleeves 41 are provided to reinforce the positions of the threaded holes on the skeleton 4 to avoid the problem that the hardness of the skeleton 4 is affected due to the opening of the threaded holes.

[0033] In some embodiments, the fitting surfaces of the side edges of the rubber part 1 and the alloy part 2 are both set as arc-shaped structures 11, and the two are connected through an adhesive layer. The adhesive layer is an adhesive. A plurality of glue overflow notches 12 are also arranged at intervals in the arc-shaped structure 11 of the rubber part 1. That is, in this embodiment, the connection surfaces of the rubber part 1 and the alloy part 2 both adopt the arc-shaped structure 11 design. Such a design can increase the connection area between the two, so as to further improve the connection strength between the two when bonding through the adhesive. In addition, the design of the glue overflow notches 12 can be used to store excess glue when the two are bonded, so as to avoid the problem of glue overflow and subsequent inconvenient cleaning.

[0034] In summary, in the present utility model, through the design of adding the reinforcing member 3 inside the rubber part 1, the reinforcing member 3 is used to support the inside of the rubber part 1, so that the whole lining plate has good elasticity and impact absorption ability, thus further enhancing the durability of the whole composite rubber lining plate. Secondly, in the present utility model, the reinforcing member 3 and the skeleton 4 are connected by the connecting member 5. This design can realize the connection and positioning of the reinforcing member 3 to ensure the stability of its position during the injection molding process. Secondly, after the connecting member 5 connects the reinforcing member 3 and the skeleton 4, it can also realize the force transmission between the reinforcing member 3 and the skeleton 4 to ensure that both the reinforcing member 3 and the skeleton 4 can obtain better force transmission, so as to achieve a better anti-impact effect.

[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
