Prevent the transmission device that cardboard tilts during transportation
Technical field
The present invention relates to carton productions, and in particular to the transmission device for preventing cardboard from tilting during transportation.
Background technique
Carton is one of life common items, it is as made of folding cardboard, encirclement, it is largely
Beautification commodity are publicized with decoration with its exquisite moulding, improve the competitiveness of commodity.Moulding and structure due to carton design past
Determine, therefore there are many its style and type 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, selects material, design icon, manufacture template, punching press, is bonded into
Box.
Currently, generally being held using carrying, the conveying that conveyer belt or transfer plate carry out cardboard due to the characteristic of cardboard itself
It easily bends or tilts, therefore be easy to appear cardboard when transmission cannot well contact with transfer plate, and then influence
Delivery quality, while cardboard can not enter next link with smooth state, influence subsequent production.
Summary of the invention
The technical problem to be solved by the present invention is to existing conveyer belts when transporting cardboard, and cardboard is easily bent or sticks up
It rises, not only influences transmission efficiency, also will affect subsequent production, and it is an object of the present invention to provide preventing cardboard from tilting during transportation
Transmission device solves the problems, such as to tilt when cardboard transport.
The present invention is achieved through the following technical solutions:
The transmission device that cardboard tilts during transportation is prevented, the support rod including conveyer belt, below conveyer belt,
It is connected with connecting rod on the support rod, the telescopic pressing plate vertical with direction of transfer is connected in the connecting rod, it is described
The two sides of pressing plate are respectively connected with telescopic expansion plate, and locating back is connected on the expansion plate, and the locating back is stretched separate
One end of contracting plate is pointed, and the bottom surface of locating back is parallel with conveyer belt, and there are heating layer, the company in the bottom surface of the locating back
There is the sensor for incuding cardboard position on extension bar.
Further, when cardboard is transmitted on a moving belt, when the intermediate position of sensor sensing to cardboard moves
When to below pressing plate, pressing plate is extended downwards, and then pressing plate is on cardboard, and at this time expansion plate in the horizontal direction to both sides
It is extended, therefore locating back is extended to both sides, and then curved side is paved, be finally reached the effect paved;
And there is heating layer to be more advantageous to the state that cardboard keeps smooth after pressing in case of heating for the bottom surface of locating back.
Preferably, the transmission device for preventing cardboard from tilting during transportation, the length of the pressing plate and the width of conveyer belt
Spend identical, the bottom surface of the pressing plate is rubber material.Bottom surface is rubber soft material, will not injure cardboard in this way.
Preferably, the transmission device for preventing cardboard from tilting during transportation, the length after the expansion plate elongation are greater than
The half of cardboard length.Guarantee that the edge of cardboard can also flatten.
Preferably, the transmission device for preventing cardboard from tilting during transportation, the angle of the pointed part of the locating back
It is 15 degree.15 degree are more advantageous to and pave the cardboard of fold again.
Preferably, the transmission device for preventing cardboard from tilting during transportation, the bottom surface of the pressing plate and the bottom of locating back
Face is all the same at a distance from the surface of conveyer belt.It is more advantageous to pressing cardboard in this way.
Compared with prior art, the present invention having the following advantages and benefits:
1, the present invention prevents the transmission device that cardboard tilts during transportation, and the present apparatus is in transmit process, to cardboard
It is flattened, prevents contact of cardboard during transmission with conveyer belt bad, and then influence the efficiency of transmission, and make paper
Plate keeps straight, and well contacts with conveyer belt, it can be made preferably to enter next process, also can be compared in subsequent handling
Good completion;
2, the present invention prevents the transmission device that cardboard tilts during transportation, and the present apparatus flattens bar during pressing
Both ends be 15 degree of tip-angled shape, therefore the pressing effect of the present apparatus is more preferable, does not need manual operation, is felt using sensor
It should operate, more saving timeliness;
3, the present invention prevents the transmission device that cardboard tilts during transportation, and present apparatus structure is simple, will not influence biography
It send, it is easy to operate.
