Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of other ways than those herein described and those skilled in the art will be able to make similar generalizations without departing from the scope of the invention. The invention is therefore not limited to the specific embodiments disclosed below.

In the production process of cardboard, carton, often need flatten or extrude for a long time, the strength of flattening among the prior art can't be controlled, and the atress is uneven, and can not press for a long time.

Referring to fig. 1 and 2, a paperboard flatting machine comprises a bottom plate 1, a gantry 2, a pressing plate 3 and a screw rod 4; the gantry 2 is arranged on the upper surface of the bottom plate 1, the gantry 2 comprises two upright posts 201 which are arranged in parallel left and right, the top ends of the two upright posts 201 are connected through a cross beam 202, a vertical screw hole matched with a lead screw 4 is formed in the middle of the cross beam 202, the lead screw 4 penetrates through the screw hole, a driven pulley 5 is fixedly connected to the middle of the lead screw 4, and the lower end of the lead screw 4 is rotatably connected with the pressing plate 3; the beam 202 is fixedly connected with a motor 6, an output shaft of the motor 6 is connected with a driving belt pulley 7, and the driven belt pulley 5 is connected with the driving belt pulley 7 through a belt 8.

In the above embodiment, the screw rod 4 penetrates through the screw hole of the cross beam 202, the lower end of the screw rod 4 is rotatably connected with the pressing plate 3, the motor drives the driven pulley 5 to rotate, the screw rod 4 is driven to rotate, the pressing plate 3 connected to the lower end of the screw rod 4 can move up and down, and the pressing plate 3 can move down to extrude an object clamped between the pressing plate 3 and the bottom plate 1. Because the lower surface of the pressing plate 3 and the upper surface of the bottom plate 1 are both large planes, the pressing plate has a flattening effect on a clamped object. Because the screw-nut mechanism is used, when the pressure plate moves in place, the motor is turned off, the pressure plate does not return, and pressure can be continuously generated.

Further, two groups of guide wheel assemblies matched with the two upright posts 201 are respectively arranged on the left side wall and the right side wall of the pressing plate 3; each group of guide wheel assemblies comprises a roller fixing plate 9 and four rollers 10, and the four rollers 10 are rotatably connected to the outer side of the roller fixing plate 9 in two rows and two columns; the inner side of the roller fixing plate 9 is fixedly connected with the left side wall or the right side wall of the pressing plate 3.

In the above embodiment, the guide wheel assemblies are provided on the left and right sides of the pressing plate 3, so that the pressing plate 3 moving up and down can be guided, and the rotation of the pressing plate 3 in the horizontal plane can be restricted.

Further, the diameter ratio of the driven pulley 5 to the driving pulley 7 is greater than 5.

In the above embodiment, since the output speed of the output shaft of the motor 6 is high and the torque is small, the ratio of the diameter of the driven pulley 5 to the diameter of the driving pulley 7 is set to reduce the speed and increase the torque, thereby increasing the pressure of the platen 3.

Further, the starting device also comprises a starting switch which is connected in series in a starting loop of the motor 6.

Further, an upper limit switch 11 and a lower limit switch 12 are arranged on the upright column 201, and the upper limit switch 11 and the lower limit switch 12 are connected in series in a starting loop of the motor 6.

In the above embodiment, the upper limit switch 11 and the lower limit switch 12 are provided on the column 201, so that the platen 3 can be ensured to be in a safe moving range.

Further, four universal wheels 13 with locks are arranged on the lower surface of the bottom plate 1.

In the above embodiment, the universal wheels with locks are arranged at the bottom of the bottom plate, so that the paperboard flatting machine can be easily moved.

The utility model discloses technical scheme for prior art's cardboard equipment of flattening, have simple structure, use manpower sparingly, extrusion pressure is big, and atress advantage such as even.
