Abstract

The utility model relates to a double-roller particle forming machine; a motor in a frame respectively drives rolls with a plurality of square pipes by a driving gear and a driven gear; the lower part of each roll is provided with an integral screen mesh; and the lower part of the screen mesh is provided with a discharge hopper. The machine can screen irregular granular materials produced by other equipment into all particles through the extrusion of the rolls and the screen mesh; the raw materials can be dry or wet with less than 35 percent of water. The machine has the advantages of high extrusion strength, high particle shaping rate, long conformal period, no easy pulverization, and is applicable to pharmacy, chemical industry, food and other fields.

Description

A kind of pair of roller granule-forming machine

[technical field]

The utility model relates to a kind of daily-use chemical industry machinery, is a kind of pair of roller granule-forming machine specifically.

[background technology]

At present, the granule-forming machine that some manufacturing enterprises use all is single roll structure, and promptly a main shaft is provided with a plurality of blades, under motor drives, and left rotation and right rotation, thus raw material is squeezed into particle.The granule-forming machine of this single roll structure, dynamics is little during extruding, yields poorly, and influences the conformal phase of the sense organ and the particle of product, and the particle storage period, is long slightly, will efflorescence.

[summary of the invention]

For overcoming the above-mentioned defective of existing single roller granule-forming machine, the utility model provides a kind of pair of roller granule-forming machine.To improve the conformal phase and the output of product.

For solving its technical problem, the utility model adopts technical scheme to be: design a kind of granule-forming machine that comprises frame, motor, decelerator, driving gear, driven gear and roller.Its feature is:

1, described roller is to be made of two independent rollers arranged side by side, each roller is provided with a rotating shaft, respectively by bearing fixing on casing, the two ends of every roller are fixed with a circular side panel respectively, are welded with many polygon square tubes on the circumference between two circular side panel equably; Be provided with whole screen cloth in the bottom of two circular rollers, the bottom of this screen cloth is fixed with discharge bucket.

2, described whole screen cloth is that two end faces are the reticulate body semicircle, that length is identical with square tube length, and the two ends of screen cloth body and central boss are fixed on the casing by the activity adjusting device respectively, and its tightness can be regulated arbitrarily by this take-up; The arc surface of screen cloth is tangent with many square tubes of roller respectively.

3, distance is 2～3mm between the cylindrical of described two rollers, and the motion mode of two rollers is for rolling or swing, and the direction of motion is in opposite directions or relative motion.

Compare with present technology, the beneficial effects of the utility model are:

1, owing to two rollers that are provided with many square tubes of employing push raw material, so crushing strength is big, grain forming rate height, and the particle conformal phase of producing is long, is difficult for efflorescence, helps improving the quality of products.

2, output height exceeds 1.5～2 times through the traditional make-up machine of PR of the present utility model on probation.

3, can change because of motion mode of the present utility model and direction, as long as change the connection status of motor and driving gear, just can realize rolling in opposite directions, about rolling or swing.As long as change the screen cloth mesh size and with the distance of roller, just can adapt to the different material screening of energy, can be widely used in the granulating and forming of various materials, easy to utilize.

[description of drawings]

Below in conjunction with the drawings and specific embodiments, the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view among Fig. 1.

Among the figure: 1, frame; 2, motor; 3, speed changer; 4, driving gear; 5, frame dividing plate; 6, feed hopper; 7, roller; 8, square tube; 9, active rotating shaft; 10, roller; 11, square tube; 12, driven spindle; 13, screen cloth; 14, discharge bucket; 15, driven gear; 16, adjustment screw.

[specific embodiment]

With reference to accompanying drawing, end in frame 1, be separated with a power cavity in 5 minutes by dividing plate, be provided with the molding cavity of feed hopper 6 with a top, in the power cavity, be provided with motor 2, this motor is connected with driving gear 4 behind speed changer 3, driving gear is connected with active rotating shaft 9, this active rotating shaft is by the two ends of bearing fixing in frame, be welded with the roller of forming by many polygon square tubes 87 on the active rotating shaft, on driving gear 4, be engaged with driven gear 15, be connected with driven spindle 12 on the driven gear, this rotating shaft on frame, is welded with the roller of being made up of many polygon square tubes 11 10 by bearing fixing on the driven spindle.Bottom at two rollers, being provided with an end face is two semicircles, the screen cloth 13 that length is identical with square tube length, the cambered surface of this screen cloth and the distance of the person in charge on the roller are tangent, screen cloth two ends and the center protuberance position of dashing forward, be fixed with by adjustment screw 16 on the biside plate of frame, be provided with discharge bucket 14 in the bottom of screen cloth, this discharge bucket is fixed on the frame.

Claims
