Technical Field

[0001] The invention relates to the field of printing presses, and in particular to a paper grabbing and discharging mechanism with a changeable bite mode. Background Art

[0002] The paper grabber is a special accessory used in printing machines, die-cutting machines and other mechanical equipment. It is mainly used to grab and convey single sheet materials, such as paper, PVC, PE, etc. Common paper grabbers are generally as follows: Figure 1 , Figure 2 The two shown are Figure 1 It is called the lower bite type. Figure 2 It is called the upper bite type. These two types of paper grabbing rows are suitable for grabbing and conveying different sheets. The lower bite type is suitable for thinner and softer sheets, and the upper bite type is suitable for harder sheets or sheets that have a certain degree of adsorption between each other.

[0003] Therefore, the conventional paper picking and discharging mechanism has poor versatility, resulting in too many parts, and the parts of each type of paper picking and discharging mechanism are not uniform, which increases the cost and makes it troublesome to replace the parts when necessary maintenance is performed.

[0012] Preferably, the lower supporting sheet is provided with supporting feet, and the grabbing end of the elastic upper pressing sheet is fixed to the extended edge of the paper grabbing array body through the supporting feet.

[0013] Preferably, the number of the supporting legs is 2.

[0014] Preferably, the number of the through slots is at least one pair.

[0015] Preferably, the elastic upper pressing plate is an elastic upper pressing plate made of 65Mn spring steel.

[0016] Preferably, the lower support plate is made of carbon steel.

[0017] Preferably, the paper grabbing array body is made of aluminum alloy.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) By providing a through slot for laterally penetrating the upper pressure plate of the spring on the paper picker body, the entire paper picker mechanism can be transformed from an upper bite type to a lower bite type paper picker mechanism, thereby saving many unnecessary parts, unifying the parts and reducing costs.

[0020] (2) By integrally forming extended edges on both sides of the paper grabbing array body, installation and fixation are easier and the versatility and expandability are enhanced.

[0021] (3) By adopting the elastic upper pressure plate made of 65Mn spring steel and the lower support plate made of carbon steel, the performance of the entire paper grabbing row structure is enhanced, the actual clamping effect is better, and a wider range of items can be grasped.

[0022] (4) The paper grabbing and discharging unit is made of aluminum alloy, which reduces the weight of the overall structure and makes the equipment easier to carry. BRIEF DESCRIPTION OF THE DRAWINGS
