The conveyer for preventing cardboard from being tilted in transportation
Technical field
The present invention relates to carton production, and in particular to the conveyer for preventing cardboard from being tilted in transportation.
Background technology
Carton is a kind of common items in life, and it is formed by folding cardboard, encirclement, and it is largely
Beautification commodity are publicized with its exquisite moulding and decoration, the competitiveness of commodity is improved.Because the moulding of carton and structure design are past
Determine, therefore its style and type are many to there is rectangle, square, polygon, different toward the features of shape by being packaged commodity
Shape, cylindrical shape etc., but its process for making is essentially identical, that is, select material, design icon, manufacture template, punching press, be bonded into
Box.
At present, general carrying, the conveying that cardboard is carried out using conveyer belt or transfer plate, due to cardboard characteristic in itself, is held
Easily bend or tilt, thus transmission when easily occur cardboard can not with transfer plate good contact, and then influence
Delivery quality, while cardboard can not enter into next link with smooth state, influences subsequent production.
The content of the invention
The technical problems to be solved by the invention are existing conveyer belts when cardboard is transported, and cardboard is easily bent or sticks up
Rise, not only influence transmission efficiency, can also influence follow-up production, it is therefore intended that offer prevents what cardboard from tilting in transportation
Conveyer, tilts when solving the problems, such as that cardboard is transported.
The present invention is achieved through the following technical solutions:
The conveyer for preventing cardboard from being tilted in transportation, including conveyer belt, the support bar below conveyer belt,
Connecting rod is connected with the support bar, the telescopic pressing plate vertical with direction of transfer is connected with the connecting rod, it is described
The both sides of pressing plate are respectively connected with telescopic expansion plate, are connected with locating back on the expansion plate, and the locating back is away from stretching
One end of contracting plate is pointed, and the bottom surface of locating back is parallel with conveyer belt, and there are zone of heating, the company in the bottom surface of the locating back
There is the sensor for sensing cardboard position on extension bar.
Further, when cardboard is transmitted on a moving belt, when the middle part of sensor sensing to cardboard is moved
To pressing plate lower section when, pressing plate is extended downwards, and then pressing plate is on cardboard, and now expansion plate in the horizontal direction to both sides
Extended, therefore locating back is extended to both sides, and then side to bending is paved, and is finally reached the effect paved;
And the bottom surface of locating back has zone of heating, in case of heating, the state that cardboard keeps smooth after pressing is more beneficial for.
Preferably, the conveyer for preventing cardboard from being tilted in transportation, the length of the pressing plate and the width of conveyer belt
Degree is identical, and the bottom surface of the pressing plate is elastomeric material.Bottom surface is rubber soft material, will not so injure cardboard.
Preferably, the conveyer for preventing cardboard from being tilted in transportation, the length after the expansion plate elongation is more than
/ 2nd of cardboard length.Ensureing the edge of cardboard can also flatten.
Preferably, the conveyer for preventing cardboard from being tilted in transportation, the angle of the pointed part of the locating back
It is 15 degree.15 degree are more beneficial for again paving the cardboard of turnover.
Preferably, the conveyer for preventing cardboard from being tilted in transportation, the bottom surface of the pressing plate and the bottom of locating back
Face is with the surface of conveyer belt apart from all same.So it is more beneficial for flattening cardboard.
The present invention compared with prior art, has the following advantages and advantages:
1st, the present invention prevents the conveyer that cardboard tilts in transportation, the present apparatus in transmit process, to cardboard
Flattened, prevent contact of the cardboard with conveyer belt during transmission bad, and then influenceed the efficiency of transmission, and made paper
Plate keeps straight, and with conveyer belt good contact, it can be made preferably to enter next operation, also can be compared with subsequent handling
Good completion;
2nd, the present invention prevents the conveyer that cardboard is tilted in transportation, and the present apparatus flattens bar during pressing
Two ends be 15 degree of tip-angled shape, therefore the pressing effect of the present apparatus is more preferable, it is not necessary to artificial operation, is felt using sensor
Should operate, more save timeliness;
3rd, the present invention prevents the conveyer that cardboard is tilted in transportation, and present apparatus simple structure does not interfere with biography
Send, it is easy to operate.
