Abstract
The utility model relates to the roller related field, and particularly relates to a press polish roller of plastic sheets, comprising a roller, wherein an empty chamber is formed in the roller; roller shafts are arranged on the left side and the right side; the press polish roller is characterized by comprising a double pipe joint; the right roller shaft of the roller is connected with the double pipe joint; the double pipe joint comprises a water inlet and a water outlet; a double runner is arranged in a mode of surrounding the outer surface of the roller; the double runner is provided with a water inlet end and a water outlet end; the water inlet end is connected with the water inlet of the double pipe joint; and the water outlet end is connected with the water outlet of the double pipe joint. The water inlet mode of the roller is that the water enters from the roller shaft; the cold water is delivered to surfaces of the roller from four sides of the roller; the delivering time is the same; and therefore, the water temperature of each roller surface is the same, and the temperature error of the roller can arrive at +/-1 DEG C. Due to the double runner and the solid roller shaft for installing the reducer, the bearing force is bigger than that of the traditional hollow shaft; and the roller solves the breaking problem of the roller shaft.
Description
Technical field
The utility model relates to the roller association area, particularly a kind of plastic plate press polish roller.
Background technology
The cylinder runner of existing three-roller calendar all is the pattern of one-in-and-one-out; But, after cold water flows to delivery port from water inlet, the water of water inlet or cold water, through the temperature heating of cylinder, delivery port is exactly a hot water, and the temperature-difference of two ends roller is too big, influences the moulding process of sheet material, thereby influences the quality of production of sheet material; And delivery port can influence cylinder roll shaft tensioner degree, because delivery port is hollow structure, weight capacity is poor, and reductor is contained in easy off-axis on the roll shaft, causes felt wrapped roll to scrap like this.The problem that these are perplexing panel production line presses for improvement.
The utility model content
The utility model provides a kind of plastic plate press polish roller, to solve the technical problem of the easy off-axis of prior art roll shaft.
The technical scheme that the utility model adopts is following:
A kind of plastic plate press polish roller comprises roller, is cavity in the roller; The left and right sides is equipped with roll shaft, also comprises double-pipe joint, and the right-hand member roll shaft of roller is connected with double-pipe joint; Double-pipe joint comprises water inlet and delivery port, is surrounded with compound runner at the outer surface of roller, and said compound runner has water inlet end and water side; Water inlet end is connected with the water inlet of double-pipe joint, and the water side is connected with the delivery port of double-pipe joint.
Further, also be provided with inner conduit in the right-hand member roll shaft of roller, the water inlet end of said compound runner is connected with the water inlet of double-pipe joint through inner conduit.
Further, the outer surface of roller also is provided with the current direction road, and the water side of said compound runner is connected with the delivery port of double-pipe joint through the current direction road.
Further, the left end roll shaft of said roller is solid roll shaft.
The water inlet pattern of the utility model roller is from the roll shaft water inlet, carries cold water each surface to roller to the roller periphery, and the time of conveying is almost equal, so, can keep the coolant-temperature gage of each roll surface to equate, the temperature error of cylinder is reached ± 1 ℃.Owing to be compound runner, the roll shaft of dress reductor is solid, and the strength of bearing is bigger than traditional hollow shaft, and this roller has solved the off-axis problem of roll shaft.
Description of drawings
Fig. 1 is existing roller structural representation;
Fig. 2 is the roller structural representation of present embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.
As shown in Figure 1, conventional plastic sheet material press polish roller, its cooling water gets into the shunting mouth of a river 2 from water inlet 1, takes away the surperficial heat of this roller through unidirectional runner 3, and simultaneously, cold water flows to refluxing opening 4; At last, water flows out from water return outlet 5.But the mode of this one-in-and-one-out causes the water can be lower than the temperature of refluxing opening 4 in the temperature of water inlet 1, has formed temperature difference like this, influences the moulding process of sheet material, thereby influences the quality of production of sheet material.And water return outlet 5 places are hollow axles, and the phenomenon of off-axis appears in this bearing Beijing South Maxpower Technology Co. Ltd force rate solid poor easily.
Be illustrated in figure 2 as the embodiment of the utility model, present embodiment is a kind of plastic plate press polish roller, comprises roller; In the roller is cavity, and the left and right sides is equipped with roll shaft 10 and roll shaft 11, also comprises double-pipe joint 6; The right-hand member roll shaft 11 of roller is connected with double-pipe joint 6, and double-pipe joint 6 comprises water inlet and delivery port, also is provided with inner conduit 7 in the right-hand member roll shaft 11 of roller; The outer surface of roller also is provided with current direction road 9, is surrounded with compound runner 8 at the outer surface of roller, and compound runner 8 has water inlet end and water side; Water inlet end is connected with the water inlet of double-pipe joint 6 through inner conduit 7, and the water side is connected with the delivery port of double-pipe joint 6 through current direction road 9.The left end roll shaft 10 of roller is solid roll shaft, as the installation shaft of reductor.
Operation principle: when the PP panel production line was started working, roller connected double-pipe joint 6 logical cooling waters, cooling roller; Double-pipe joint 6 is a water inlet on one side, and another side is a delivery port, and cooling water passes through water inlet; Through the compound runner 8 of inner conduit 7 entering rollers, carry the surface of cooling water through compound runner 8 to the periphery of roller to roller, the time of conveying is almost equal; So; This structure keeps the water temperature of each roll surface to equate, current are back to the delivery port of double-pipe joint 6 through current direction road 9 then, form a hydronic process.Owing to adopt compound runner 8, current are from double-pipe joint 6 water inlets, again from double-pipe joint 6 water outlets.Therefore, current all are from 11 turnover of right-hand member roll shaft, only need make hollow to the right-hand member roll shaft, and left end roll shaft 10 remain solid shafting.Therefore, left end roll shaft 10 can be as the reductor installation shaft, owing to be solid shafting, the strength that this bearing receives is very big, and reductor installs, and the phenomenon of off-axis can not occur.
