Description

Three-roller open mill

Technical field

The present invention relates to a kind of three-roller open mill.

Background technology

At present, in the middle of the rubber industry of China, mill can be described as one of the most frequently used rubber preparing device, particularly in tyre industry, mill is an indispensable important step in the production process especially, because mill is good to the melting effect of sizing material, and bearing capacity is strong, and is sturdy and durable, so extensively adopted by rubber industry, be used for the following subsidiary engine of banbury more or be used for the heat refining film and to calender for glue etc., usually can use many mill equipment in a slat gum production line, therefore, whether the work of mill is stable, whether the melting effect to sizing material is good, is directly connected to the quality and the efficient of article of manufacture.

What traditional mill was all adopted basically is freestanding two roller frame modes, see Figure of description Fig. 1, the mill of this structure is (flow process needs about three) when arranging flow process, owing to be subjected to the restriction of operating space, spacing between the individual device is bigger, taken bigger factory building space, in use, the operator also can only operate single device, concerning the manager of enterprise, and such apparatus arrangement mode, both wasted limited factory building space, can not effectively utilize the human resources of enterprise again, therefore, increasing user proposes new requirement on the product structure of mill, on the basis that does not influence production throughput, reduce the occupation of land space of mill as far as possible, and improve the operability of product, so just can save lot of manpower and material resources.

In order to realize user's the demand to equipment, we determine the product structure of mill is redesigned after the operating position of having studied most of users, two two roller mills are integrated, rationally arrange with three rollers and to realize the function of two two roller mills, intermediate calender rolls is a stationary roll, up-down rollers is mobile distance regulating roller, and the speed ratio between three rollers can be realized by the variable speed electric motors, particularly of speed ratio gear or three independent transmissions.

Summary of the invention

At problems of the prior art, the object of the present invention is to provide and a kind ofly take up an area of that the space is few, the three-roller open mill of high efficiency.

The technical scheme that the present invention is adopted for achieving the above object is: a kind of three-roller open mill, comprise base, be positioned at the body of holding about base, be connected in the roller of body, be positioned at the Hooks coupling universal coupling on roller top, be positioned at the roller temperature adjusting device of roller end, the transmission device that is connected with the roller top, striker plate, safety device, roll-setting gear, pneumatic cutter, lubricating system, upper conveyor belt, following conveyer belt and be connected the up and down roller (guide) apron between the conveyer belt, described roller is by top roll, central roll and lower roll vertically rearrange, the angle of inclination of top roll and vertical direction is the 30-60 degree, and the angle of inclination of roller and vertical direction is the 0-15 degree.

The angle of inclination of described top roll and vertical direction is preferably 60 degree.

The angle of inclination of described lower roll and vertical direction is preferably 15 degree.

Described top roll and described lower roll are mobile distance regulating roller.

Described central roll is a stationary roll.

Described safety device is arranged on the top of top roll and the bottom of lower roll.

Described striker plate is arranged at the two ends that reach the roller between described central roll and the lower roll between described top roll and the central roll.

After adopting technique scheme, the present invention is relative with prior art to have following beneficial effect:

1. this three-roller open mill is rationally arranged with three rollers, can realize the function of two two roller mills.

2. this three-roller open mill occupation of land space is few, high efficiency.

Description of drawings

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of prior art mill;

Fig. 2 is the front view of three-roller open mill of the present invention;

Fig. 3 is the side view of three-roller open mill of the present invention.

Among the figure: 1, roller temperature adjusting device; 2, body; 3, roller; 4, Hooks coupling universal coupling; 5, transmission device; 6, striker plate; 7, safety device; 8, roll-setting gear; 9, pneumatic cutter; 10, lubricating system; 11, following conveyer belt; 12, upper conveyor belt; 13, base; 14, roller (guide) apron.

The specific embodiment

As Fig. 2, shown in Figure 3, this three-roller open mill comprises roller temperature adjusting device 1, body 2, roller 3, Hooks coupling universal coupling 4, transmission device 5, striker plate 6, safety device 7, roll-setting gear 8, pneumatic cutter 9, lubricating system 10, following conveyer belt 11, upper conveyor belt 12, base 13, roller (guide) apron 14, body 2 is positioned at two ends, base 13 left and right sides, roller 3 is connected on the body 2, universal-joint spindle 4 is positioned at the top of roller 3, roller temperature adjusting device 1 is positioned at the end of roller 3, transmission device 5 is connected in roller 3 tops, the roller 3 of mill of the present invention adopts top roll, three rollers of central roll and lower roll, three rollers are vertically arranged, wherein, top roll and vertical direction inclination 30-60 degree, be preferably 60 degree, lower roll and vertical direction inclination 0-15 degree are preferably 15 degree, and top roll and lower roll are mobile distance regulating roller in these three rollers, removable up and down, central roll is a stationary roll.

Top roll and vertical direction inclination 30-60 degree, stressed to reduce central roll, being beneficial to operation increases Sheng glue area simultaneously; By roll-setting gear 8, roller is removable up and down, to realize different roll gap size requirements; Central roll is fixed, and is reference roller; Lower roll and vertical direction inclination 0-15 degree are beneficial to sizing material and enter central roll, following roller gap, and by roll-setting gear 8, roller is removable up and down, to realize different film thickness requirements; Between top roll and the central roll and between central roll and the lower roll, all be provided with striker plate 6, spill roll surface to prevent material at the roller two ends; Be provided with safety device 7 at top roll and lower roll place, prevent to cause the damage of key components and parts such as roller, frame, bearing because of the roller overload.
