Description

Technical Field

[0001] The utility model relates to a paper feeder, in particular to a manual adjustment mechanism for a feeder head of the paper feeder. Background Art

[0002] Sheet feeders are widely used in sheet-fed printing machinery and equipment such as screen printing machines, gravure printing machines, fully automatic die-cutting machines, and paper laminating machines. A paper stacking table for placing paper piles is set at the entrance section, and the paper is separated and fed into the paper feeder table in sequence through the feeder head. As the paper is continuously output, the paper pile monitoring system of the paper feeder increases the height of the paper pile at any time to ensure uninterrupted paper feeding.

[0003] The position of the feeder head is changed by setting an adjustment mechanism, so as to realize the feeding head's grabbing operation for papers of different sizes and models. According to different market demands, the selling price of the paper feeder is also divided into a variety of high and low grades, and the production cost of the equipment needs to be considered accordingly according to the selling price. Therefore, according to different paper feeders, the existing feeder head adjustment mechanism is mainly divided into automatic and manual. In order to reserve enough paper loading space below, the adjustment mechanism will be installed at a high place of the paper feeder with the feeder head. For the manual adjustment mechanism, this installation height often requires the operator to use climbing tools to operate the adjustment mechanism. The operation is cumbersome and there will be certain safety hazards. In order to avoid the existing manual adjustment mechanism structure on the market, the present invention is conceived. Utility Model Content

[0004] The utility model aims to provide a manual adjustment mechanism for a feeder head of a paper feeding machine. The manual adjustment mechanism is easy to adjust, thereby reducing potential safety hazards in the adjustment process and has a novel structure.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a manual adjustment mechanism for a feeder head of a paper feeder, comprising a frame and a feeder head, the frame is movably provided with a mounting frame for mounting the feeder head, the feeder head is movably provided on the mounting frame, the mounting frame is provided with a manual adjustment component that moves with the mounting frame and is used to drive the feeder head to reciprocate horizontally, the frame is provided with a manual lifting component for driving the mounting frame to rise and fall, and the control end of the manual lifting component extends close to the ground.

[0006] By adopting the above technical solution, by setting the control end of the manual lifting component to extend close to the ground, the staff can operate the control end to control the manual lifting component without the help of climbing tools. The height of the mounting frame is lowered by the manual lifting component, so that the staff can adjust the position of the feeder head through the manual adjustment component without the help of climbing tools. The above setting structure makes the adjustment more convenient, thereby reducing the safety hazards in the adjustment process and the structure is novel.

[0007] It is further configured as follows: one side of the mounting frame is rotatably connected to the frame via a rotating structure, and the manual lifting assembly includes a linkage component connected to the mounting frame located on the other side of the rotating structure in the rotating direction, and an extension rod connecting the linkage component and the control end.

[0008] By adopting the above technical solution, the extension rod is set to compensate for the height difference formed, and the control end controls the mounting frame to rotate around the rotating structure through the extension rod and the linkage component, so as to adjust the height of the mounting frame to achieve the purpose of lifting control.

[0009] It is further configured as follows: the linkage component includes a linkage column that is lifted and slidably arranged on the frame, a linkage chain that connects the linkage column and the extension rod, a guide sprocket that is rotatably arranged on the frame and used to guide the linkage chain to switch directions, and a linkage block that is rotatably arranged on the mounting frame and connected to the linkage column, and the extension rod is threadedly connected to the frame.

[0010] By adopting the above technical solution, the extension rod is threadedly connected to the frame to pull the linkage column and the linkage block through the linkage chain to change their position height, so as to achieve the lifting and lowering adjustment of the mounting frame. By setting the linkage block and the mounting frame as a rotating structure, the structural movement interference caused by the sliding linkage column structure and the rotating mounting frame structure is avoided to ensure the feasibility of the structure.

[0011] It is further configured that: the rotating surface formed by the rotation of the linkage block is parallel to the rotating surface formed by the rotating structure, and the rotating structure includes an offset stroke hole arranged on the frame and a rotating shaft arranged on the mounting frame and rotatingly matched with the offset stroke hole.

[0012] By adopting the above technical solution, the cooperation between the offset stroke hole and the rotating shaft can compensate for the rotation stroke deviation formed by the mounting frame during the rotation process through the offset stroke of the offset stroke hole, while satisfying the rotation function of the mounting frame, thereby avoiding structural interference and ensuring the feasibility of the structure.

[0013] It is further configured as follows: the manual adjustment component includes an adjustment screw rotatably arranged on the mounting frame and passing through the feeder head and threadedly connected thereto, and an adjustment hand wheel rotating with the adjustment screw.

[0014] By adopting the above technical solution, the adjusting hand wheel drives the adjusting screw to rotate, and the thread matching structure drives the feeder head to slide on the mounting frame.

[0015] It is further configured as follows: a positioning side plate abutting against the mounting frame is provided on one side of the frame located in the rotation direction of the mounting frame, and when the mounting frame abuts against the positioning side plate, the feeder head is in a horizontally arranged state.

[0016] By adopting the above technical solution, the positioning side plate is arranged to position the adjusted feeder head, so as to ensure that the adjusted feeder head can always be in a horizontal state to achieve stable gripping of the paper.

[0017] In summary, the utility model has the following beneficial effects: the utility model is easy to adjust, thereby reducing the potential safety hazards in the adjustment process and has a novel structure. BRIEF DESCRIPTION OF THE DRAWINGS
