Abstract

The utility model relates to a rubber mill, which comprises a base, a frame, an upending bracket, a discharging bracket, a front roller, a rear roller and a motor, wherein the motor transfers power to the front and the rear rollers through a gear box and a coupler. A scraper is arranged above the rear roller, the tail end of the scraper is in close joint with the rear roller and opposite to the rotating direction of the rear roller, and particularly, the scraper is arranged along the tangential direction of the rear roller. Rubber adhered to the rear roller can be scraped off by the scraper when the rear roller is rotating, so as to solve the problem that the rubber is wound on the rear roller during the processing. The scraper can be arranged either above the rear roller, or below the front roller, so that the scraper below the front roller can be avoided from being wound by the rubber. The utility model has the advantages of avoiding the front roller from being wound by the rubber, and trimming the edges and the dimension specifications of rubber sheets during discharging.

Description

A kind of rubber mixing mill

Technical field

The utility model relates to a kind of rubber processing device, particularly a kind of rubber mixing mill.

Background technology

Along with the continuous development of plastic blend modification technology, people have had the strict multinomial performance requirements such as degraded, specific energy control that prevent to physical blending, chemical reaction, the material of high fill-ratio, the temperature-sensitive material of rubber and plastics.

Opening rubber mixing machine (mill) is that equipment is moulded in the refining of open type refining glue, mainly is to be rotated in opposite directions by two cylindric rollers, and the rotating speed difference produces shear action thereby produce speed difference to material, allows material obtain plasticizing or mixing.Front roller wheel is positioned at the below of rear roll under the normal operating conditions, and the rotating speed of front roller wheel is higher than rear roll; Rubber raw materials will push and shear through between the forward and backward running roller rubber raw materials, can fall into the blank frame along with the rotation of front roller wheel through the rubber sheet after the forward and backward running roller processing.Existing mill is when processing rubber, and rubber is in the temperature environment of about 80 ℃ in the machine of beginning to pratise, and the viscosity of rubber increases.In the time of between rubber is through front roller wheel and rear roll, rubber usually can be wrapped on the rear roll, and twines tighter and tighter along with rear roll rotates.When this situation occurring, operating personnel just need close mill immediately and clear up the rubber that is wrapped on the rear roll, in case rear roll is stuck by rubber.

Rubber also may be wrapped on the stirring running roller of tilting trestle, causes the stirring running roller stuck.

Because portioned product has the special size specification, the rubber after beginning to pratise need carry out secondary operations to meet the dimensional requirement of product, strengthens workman's labor force and delays manufacturing schedule.

In sum: need a kind of rubber raw materials that prevents to be wrapped on the running roller of mill and can conveniently to control the rubber mixing mill of product specification at present, to improve efficiency of equipment and to reduce equipment failure rate.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, relates to a kind of production efficiency height, stable working state, rubber that equipment failure rate the is low machine of beginning to pratise.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The utility model relates to a kind of rubber mixing mill, mainly comprise base, frame, tilting trestle, discharge rack, front roller wheel, rear roll and motor, motor is connected with rear roll with front roller wheel with shaft coupling by gear-box, motor by gear-box and shaft coupling with power be transferred to front roller wheel and after.Above rear roll, be provided with scraper, the end of scraper and rear roll fit and with the rotation direction of rear roll in opposite directions, more specifically say so the tangential direction setting of scraper along rear roll.Stick at the rubber on the rear roll and when rear roll rotates, can be scraped, solved rubber in the process and be wrapped in problem on the rear roll by scraper.Except being provided with on the rear roll the scraper, above-mentioned scraper can also be set on front wheel, scraper is positioned at the below of front roller wheel can avoid twining on the scraper sheet rubber.

Above the stirring running roller on the tilting trestle of rubber mixing mill described in the utility model, be provided with scraper, the end of scraper and stirring running roller fit and with the rotation direction of stirring running roller in opposite directions, more specifically say so the tangential direction setting of scraper along the stirring running roller.

Being horizontally arranged with a transverse cross-sectional shape on discharge rack is circular connecting rod, is provided with two directive wheels that can slide on connecting rod in the connecting rod both sides, is provided with one or more cutting knife simultaneously between two directive wheels.Directive wheel and/or cutting knife flexibly connect by linking arm and connecting rod, and described directive wheel flexibly connects by a linking arm and connecting rod, is provided with bolt between linking arm and connecting rod, linking arm can be fixed on the connecting rod on certain position of fixing.Described cutting knife also can be selected the identical connected mode of directive wheel and connecting rod with the connected mode between the connecting rod, and the quantity of cutting knife is set according to the specification that will produce product.Under the sheet rubber of the irregularity cutting knife from the discharge rack through out-of-date, cutting knife is neat and cut into needed specification with its edge cuts, in the purpose that directive wheel is set on the discharge rack is to prevent that rubber from cutting edge or twisting during cut form, causes sheet rubber not meet product specification and need turn over the worker again.

Adjust the position of cutting knife and the distance between definite cutting knife for convenience and be provided with rule in connecting rod, the staff can set distance between the cutting knife with reference to the rule on the connecting rod according to the width of the sheet rubber of needed production.

The utility model relates to again at existing rubber mixing mill, and possessing has following products characteristics and use advantage:

1. production efficiency height of the present utility model can carry out product finishing and product specification processing immediately after rubber is opened refining;

2. the utility model is wrapped on the running roller possessing the sheet rubber of preventing, reduces equipment failure rate.
