DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the drawings needed to be used in the embodiment description will be briefly introduced as follows, and obviously, the drawings in the following description are some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor.

[0018] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0019] Embodiments, such as Figs. 1-3The embodiment aims to improve the feeding efficiency of the folding machine, and meanwhile, reduce the labor intensity. To this end, the folding machine automatic feeding platform comprises a square placing plate and a stand column arranged at four corners of the placing plate. The size of the placing plate should be able to easily accommodate a common tray. In this way, the stacked paper is placed on the tray, and then the tray is placed on the placing plate.

[0020] In order to realize the conveying of the paper, the placing plate is arranged between the stand columns and is lifted. The lifting mode of the placing plate can be various, such as a cylinder is arranged at the bottom of the placing plate, or a driving motor is arranged on the placing plate, and a rack is arranged on the stand column to realize the lifting.

[0021] In the embodiment, the stand column is hollow, that is, the stand column is a square tube structure. A lifting lead screw is arranged in the stand column. Specifically, a motor is arranged at the top of the stand column, and the output end of the motor is connected with the lifting lead screw. In this way, the lifting lead screw is rotatably arranged in the stand column. A lead screw nut is sleeved on the lifting lead screw. Of course, a nut seat is sleeved on the lead screw nut. Guide spindles are arranged at the two sides of the lifting lead screw. The guide spindles pass through the nut seat to ensure the stability of the nut seat. A connecting piece is arranged at the corner of the placing plate, and the end of the connecting piece away from the placing plate is connected with the lead screw nut.

[0022] In order to limit the tray, a baffle is arranged between any two adjacent stand columns. In this way, when the tray is placed on the placing plate, the baffle limits the tray, and also facilitates the placing of the tray.

[0023] In order to facilitate the paper to enter the table of the folding machine, a guide seat is arranged at the top of the baffle. A negative pressure paper feeding wheel is arranged obliquely above the guide seat. The negative pressure paper feeding wheel is provided with uniform holes on the circumferential surface of the wheel body. The holes generate suction force by negative pressure. The suction force sucks the uppermost paper of the tray. Since the negative pressure paper feeding wheel rotates, the paper is carried away.

[0024] Therefore, the negative pressure paper feeding wheel is rotatably arranged above the placing plate. In order to convey the paper sucked by the negative pressure paper feeding wheel, guide plates are arranged at the two sides of the negative pressure paper feeding wheel. The guide plates are arranged above the guide seat and are arranged in an obtuse angle. In this way, the paper sucked and carried away by the negative pressure paper feeding wheel can only move forward and downward (the guide plate is arranged in an obtuse angle, which includes a horizontal part and an inclined part, and the inclined part is arranged downward) due to the limitation of the guide plate, and cannot rotate with the negative pressure paper feeding wheel. The paper moving forward and downward is moved to the table by inertia, and then passes through the paper feeding wheel on the table to realize feeding.

[0025] In the embodiment, in order to control the distance between the bottom surface of the guide plate and the top surface of the guide base, a cross bar is arranged between the two vertical columns, a connecting piece is sleeved on the cross bar, the connecting piece is composed of two rectangular metal blocks, a hole is arranged in the middle of the connecting piece, then the connecting piece is clamped on the cross bar by means of a bolt, a vertical plate is arranged at the end of the horizontal part of the guide plate away from the inclined part, a slot hole is formed in the vertical plate, thus the vertical plate is fixed on the connecting piece by means of a bolt passing through the slot hole, and the height is adjustable.

[0026] In order to facilitate the paper to pass through the guide table, the top surface of the guide base is chamfered on both sides.

[0027] In order to more conveniently control the lifting height of the placing plate, a proximity switch is further arranged above the placing plate, and the proximity switch is arranged close to the top of the vertical column. In this way, when the paper contacts the proximity switch, the lifting motor stops working. Of course, the infrared sensor, the laser sensor, the travel switch and the like can be used to determine the lifting height of the placing plate, and of course, the manual control mode can also be used.

[0028] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied in other fields, but any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments still fall within the protection scope of the present application.
