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 supply glue etc., in a slat gum production line, can use many mill equipment usually, therefore to calender; Whether whether the work of mill is stable, good to the melting effect of sizing material, 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, sees Figure of description Fig. 1, and the mill of this structure is (flow process needs about three) when arranging flow process; Owing to receive the restriction of operating space, the spacing between the individual device is bigger, has taken bigger factory building space; In use, the operator also can only operate single device, concerning the manager of enterprise; Such apparatus arrangement mode had both been wasted limited factory building space, can not effectively utilize the human resources of enterprise again; Therefore, more and more users 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 designed again after the operating position of having studied most of users; Two two roller mills are integrated, rationally arranged with three rollers and realize that the function of two two roller mills, intermediate calender rolls are stationary roll; Up-down rollers is for moving distance regulating roller, and the speed ratio between three rollers can be realized through the variable speed electric motors, particularly of speed ratio gear or three independent transmissions.

Summary of the invention

To the problem that exists in 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 present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of three-roller open mill; Comprise base, at the body of holding about base, be connected in roller between two bodies, at the Hooks coupling universal coupling on roller top, the roller (guide) apron between the conveyer belt at the terminal roller temperature adjusting device of roller, the transmission device that is connected with the roller top, striker plate, safety device, roll-setting gear, pneumatic cutter, lubricating system, upper conveyor belt, time conveyer belt and about being connected; Said roller is vertically rearranged by top roll, central roll and lower roll; The angle of inclination of top roll and vertical direction is the 30-60 degree, and the angle of inclination of lower roll and vertical direction is the 0-15 degree.

Said top roll and said lower roll are for moving distance regulating roller.

Said central roll is a stationary roll.

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

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

After adopting technique scheme, the present invention and prior art have following beneficial effect relatively:

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

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.

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

Like 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, and body 2 is positioned at base 13 right ends; Roller 3 is connected between two bodies 2, and universal-joint spindle 4 is positioned at the top of roller 3, and roller temperature adjusting device 1 is positioned at the end of roller 3; Transmission device 5 is connected in roller 3 tops, and the roller 3 of mill of the present invention adopts top roll, central roll and three rollers of lower roll, and three rollers are vertically arranged; Wherein, Top roll and vertical direction inclination 30-60 degree are preferably 60 degree, lower roll and vertical direction inclination 0-30 degree; Be preferably 30 degree; Top roll and lower roll are for moving distance regulating roller in these three rollers, and 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; Through 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 get into central roll, following roller gap, and through 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.
