Abstract
The utility model discloses a lever type rolling mechanism which comprises a machine frame, an upper roller, a central roller, a lower roller, two rocking rods and two drive devices, wherein the central roller is fixed on the machine frame by a fixing seat. The two rocking rods are fixed on the machine frame by fulcrums separately. The upper roller and the lower roller are arranged on upper ends of the two rocking rods respectively. The two drive devices are both installed on the inner side of the machine frame, and are twisted and connected with lower ends of the two rocking rods respectively in opposite directions. The utility model has the advantages that the press force of a hydraulic cylinder is increased by the lever principle to realize pressurization under the condition of the same parameter of a hydraulic system. A tilting mechanism of the rocking rods is used for realizing the motive clamping and the pressurization of an upper roll and a lower roll. The hydraulic cylinder or a barometric cylinder is arranged on the inner side of the machine frame instead of the original place of the external side of the machine frame, which can realize a more compact structure, and thus, the volume of the whole rolling mechanism is greatly reduced.
Description
Technical field
The utility model relates to the technical field of plastics machinery production line, relates to more particularly that a kind of plastics are extruded, the roller press mechanism of press polish in the sheet material equipment, rolling equipment.
Background technology
At present, sheet in the plastics machinery, in the press polish and calender device of panel production line, dual mode is adopted in pressurization mostly between its roller, be that mechanical system pressurization and liquid (gas) pressure mode are pressurizeed, with oblique three-roller calendar is example (as shown in Figure 1): the lever roller press mechanism, comprise frame, upper roll wheel, middle roll, lower roll wheel and two hydraulic cylinders, middle roll is installed on the frame by holder, upper roll wheel and lower roll wheel are connected with two hydraulic cylinders up and down respectively, the running roller seat that utilizes the direct promotion of two hydraulic cylinders that running roller is installed slides on frame, the pressurization that realizes lower roll wheel and middle roll and middle roll and upper roll wheel clamps, the shortcoming of this structure is that pressure is subjected to oil (gas) cylinder pressure or the restriction of mechanical compaction power, simultaneously because the existence of the frictional force between each roller seat and frame, cause mobile time vibration, same reason, in the time of also can causing roll-in tight because of roller spare sheet, roller vibration during the plate load variations, be reflected in and then be sheet on the goods, the instability of board quality, simultaneously, this kind of pressue device mounting means has also determined calender bigger along the glide direction size, thereby has determined the huge of press polish (prolonging) machine structure.
The utility model content
The purpose of this utility model provides a kind of simple and reasonable for structure, compact in order to solve above-mentioned deficiency exactly, can effectively promote a kind of lever roller press mechanism that compresses and move stability.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
The lever roller press mechanism, comprise frame, upper roll wheel, middle roll, lower roll wheel, two rocking bars and two drive units, middle roll is installed on the frame by holder, two rocking bars are installed on the frame by its fulcrum respectively, upper roll wheel and lower roll wheel are separately positioned on the upper end of two rocking bars, two drive units are installed in the inboard of frame, and become rightabout respectively with the lower end hinge joint of two rocking bars.
Described drive unit can be a hydraulic cylinder, also can be pneumatic cylinder.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: utilize lever principle to increase the thrust of hydraulic cylinder, can realize the supercharging under the same hydraulic system parameters situation; Utilize the rocking bar swing mechanism to realize that up-down rollers moves clamping and pressurization,, can realize the steady fast folding of running roller up and down, the pressure stability in the time of can also realizing ordinary production owing to there has not been the frictional force of running roller seat and frame to exist; Change hydraulic cylinder or pneumatic cylinder into be arranged on frame inboard by the original frame outside that is positioned at, compact more on can implementation structure, thus reduced the volume of whole roller press mechanism greatly.
Description of drawings
Fig. 1 is a roll squeezer structural representation of the prior art;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
By shown in Figure 1, Fig. 1 is a roll squeezer structural representation of the prior art, it is that the roller seat 10,11 that adopts hydraulic cylinder 7,8 or the direct promotion of pneumatic cylinder that running roller 2,4 is installed slides on frame 1, when roller seat 10,11 when 1 of frame is slided relatively, because the existence of roller seat 10,11 and 1 frictional force of frame, make and when mobile, can vibrate, roller vibration in the time of equally also can causing roll-in to compress during because of roller spare sheet, plate load variations is reflected on the goods then the instability for sheet, board quality.
By shown in Figure 2, Fig. 2 is a structural representation of the present utility model, the lever roller press mechanism, comprise frame 1, upper roll wheel 2, middle roll 3, lower roll wheel 4, two 5,6 and two hydraulic cylinders 7,8 of rocking bar, middle roll 3 is installed on the frame 1 by holder 9, two rocking bars 5,6 are installed on the frame 1 by its fulcrum 501,601 respectively, upper roll wheel 2 and lower roll wheel 4 are separately positioned on the upper end of two rocking bars 5,6, two hydraulic cylinders 7,8 are installed in the inboard of frame 1, and become rightabout respectively with the lower end hinge joint of two rocking bars 5,6.Above-mentioned hydraulic cylinder also can be replaced by pneumatic cylinder.
The thrust that the utility model has made full use of lever principle increase hydraulic cylinder realizes the pressurization under the same hydraulic system parameters situation; Utilize the rocking bar swing mechanism to realize that up-down rollers moves clamping and pressurization,, not only can realize the steady fast folding of running roller up and down, the pressure stability in the time of can also realizing ordinary production owing to there has not been the frictional force of running roller seat and frame to exist; Change hydraulic cylinder or pneumatic cylinder into be arranged on frame inboard by the original frame outside that is positioned at, compact more on can implementation structure, thus reduced the volume of whole roller press mechanism greatly.
