Description

Panel alignment unit of dalle production line

Technical Field

The utility model belongs to the technical field of dalle processing, specifically a panel aligns unit for dalle production line.

Background

In actual production, the assembly line is used in the production of decorative boards, wood floors, composite floors and the like made of materials such as PVC. On a production line, a plurality of rollers are used to transfer the sheets. For example, the PVC decorative board is only about 1cm, is made of PVC or doped with wood fiber, is light in weight and is a development trend for light weight.

Because the weight of the plate is light, the friction force between the bottom surface of the plate and the surface of the roller is small in the transmission process, once the plate jumps and the like, the plate can deflect, one corner is in front, the other corner is behind, and the plate moves forwards obliquely. When the plate enters the processing station, the plate needs to be positively moved in and out under most conditions so as to ensure the processing quality.

In the processing process, the wear-resistant glue coating process does not need a special accurate station, the processing times are more, most of plates need to be subjected to multiple gluing and multiple curing, and the deflection influence is large and the curing time of each part of the plates in the curing process is long. Before the wear-resistant glue and the like are not cured, the surface of the plate is provided with a glue layer, so that the operation of the deviation correcting device is not easy to realize.

Disclosure of Invention

Based on the characteristics of panel processing, in order to solve the above-mentioned problem that exists among the prior art, the utility model provides a panel of dalle production line aligns the unit, and this unit is suitable for and adds alone and establishes the assembly line in, specifically does:

a plate alignment unit of a decorative plate production line comprises a unit underframe, a first conveying roller, a baffle roller and a second conveying roller; setting the plate advancing direction as front;

the first conveying roller and the second conveying roller are respectively connected to two sides of the unit underframe in an end-to-end rotating manner;

the second conveying roller is arranged in front of the first conveying roller;

the number of the second conveying rollers is one or more than one, the second conveying rollers are parallel to the horizontal plane, and the second conveying rollers are vertical to two sides of the unit underframe;

the first conveying rollers are parallel to each other; the head end of the first conveying roller is slightly higher (not more than 5mm) than the height of the second conveying roller, and the tail end of the first conveying roller is slightly lower (not more than 5mm) than the height of the second conveying roller; the lower end of the first conveying roller is connected to the first edge of the unit underframe; in the projection of the first conveying roller on the horizontal plane, the head end of the first conveying roller is in front of the tail end of the first conveying roller (the position difference between the head end and the tail end is 10-30 mm);

a plurality of baffle rollers are connected to the first edge of the unit underframe, the rotating shafts of the baffle rollers are vertical to the horizontal plane, and at least 2 baffle rollers are connected between adjacent first conveying rollers;

the first conveying rollers are connected to the same driving motor;

the first conveying roller rotates in the forward linear speed direction forward on the top surface of the first conveying roller.

The present alignment unit may be installed as a stand-alone unit between the line and the working devices of the respective process units (e.g., between the UV glue roll coater and the UV curing machine). Through the slope in the skew place ahead of the first conveying roller of specific design to and keep off the roller, make the action of panel on first conveying roller as: once the sheet enters the range of the first conveying roller, the sheet integrally slides to one side of the baffle roller, and is aligned by the baffle roller, and then the roller has a left-right force of inclining forwards, and further the sheet leans against the baffle roller. When the plate enters the second conveying roller, the plate is in a state of being opposite to the inlet of the next procedure.

Further:

the connecting mechanism between the first conveying roller and the driving motor comprises a transmission shaft; the head end and the tail end of the transmission shaft are rotatably connected to the unit underframe and are arranged below the first conveying roller; the length of the transmission shaft is consistent with the advancing direction of the plate; the transmission shaft is connected with an output shaft of the driving motor through a chain wheel transmission structure;

a first annular groove is formed in the outer wall of the head part of the first conveying roller; a plurality of second annular grooves are formed in the transmission shaft, each second annular groove corresponds to one first annular groove of the first conveying roller, and the corresponding first annular groove and the corresponding second annular groove are connected through an annular belt; each annular belt is twisted into an 8 shape;

the base of the driving motor is fixed on the unit underframe, and the rotating shaft of the driving motor is parallel to the transmission shaft.

Because the whole of the first conveying roller is towards the obliquely upper part and adopts the traditional structure, the optimal direction is not easy to adjust. And adopt the endless belt structure, because the whole of endless belt has flexibility and elasticity, its direction of drive becomes "self-adaptation", for the transmission of first transport roller, simple and practical. Meanwhile, the board is light in weight, and the power of the needed motor and the transmission structure is not large, so that the transmission structure can completely meet the driving requirement.

The efficiency of chain wheel transmission is the highest, if other hindrance circumstances appear, can slide (the belt skids) between annular belt and two recesses, can avoid the incident.

In practice, the sprocket drive position of the drive motor corresponds to the middle position of the drive shaft. Under this structure, the motor application of force is in the transmission shaft intermediate position, and transmission effect is better.

The transmission shaft and the first conveying roller are the same in outer diameter. Under this structure, the contact area of the annular belt and the two is the closest, and the whole frictional force is the most equal. Meanwhile, the gear ratio calculation of the motor drive transmission shaft is facilitated.

In specific implementation, the annular belt can adopt an anti-aging silicon-based elastic rubber ring, and the diameter of the cross section of the annular belt is 3-5 mm.

The utility model discloses help improving motor utilization efficiency, it is more simple and convenient to maintain.
