Abstract

The invention discloses a double paper-input control device, belonging to the technical field of printing and packaging. The device capable of being installed in a printer or a paper packaging machine controls double pieces of paper not to be input. The structure comprises a sensor, a spring, a swing arm, a roller and the like. The double paper-input control device adapting to the grammage of a variety of paper is simple in structure, small in size, convenient in adjustment and high in sensitivity. By using the device, a remarkable economic effect can be acquired.

Description

The two control setups of opening of defeated paper

Technical field:

The present invention relates to sheet-fed printing and paper article packaging machinery, belong to printing paper bag packing technique field.

Background technology:

Printer and paper article packaging machinery have in the market does not have twoly to open control setups, or complex structure, and adjustment is inconvenient, and sensitivity is low, incompatibility paper gram number size, and very difficult control does not go out two opening, and causes product rejection, or stops up machine.

Summary of the invention:

The technical matters that the present invention will solve to the shortcoming of above existence, designs the two control setups of opening of a kind of dynamo-electric autofeed; Can be installed in the defeated paper part of printer or paper article packaging machinery; This apparatus structure is simple, and volume is little, and is easy to adjust; Highly sensitive, therefore two opening or many phenomenons can not appear.

The two control setups of opening of the defeated paper of the present invention comprise that inductive type proximity transducer 1, plunger 2, spring perch 3, transfer roller 4, spring set pin 5, stage clip 6, adapter plate 7, swing arm 8, bearing pin 9, roller shaft 10, roller 11, back-up ring 12 are formed, and this device install machinery is failed the paper part; Swing arm 8 is installed on the adapter plate 7 through bearing pin 9, and along bearing pin 9 swings, roller 11 is through roller shaft 10; Back-up ring 12 is fixed in the swing arm 8, and roller 11 is rotatable, and plunger 2 is installed in the spring perch 3; Through screw adjusted stage clip 6 pressure, i.e. roller 11 pressure, spring perch 3 is installed on the adapter plate 7; Spring set pin 5 is fixed in the swing arm 8, and inductive type proximity transducer 1 is installed on the adapter plate 7, and transfer roller 4 rotates and drives roller 11 rotations; Swing arm 8 adjusted screws are to proximity transducer 1 swing when sheet-fed is come, because of detecting apart from brief biography sensor 1 less than, machine normal operation; Swing arm 8 adjusted screws are to proximity transducer 1 swing when coming for two, and because of distance strengthens, sensor 1 detects swing arm 8 adjusted screws and sends instruction stop; Avoid two opening to import next procedure into, the distance between set screw scalable proximity transducer 1 and the swing arm is housed in the swing arm 8, roller shaft 10 and bearing pin 9 distances are because of greater than bearing pin 9 and proximity transducer 1 distance; The big more swing of distance is big more, general ratio about 1: 5.

Adopt two its advantages of control setup of opening of the defeated paper of the present invention to be: simple in structure, volume is little, and perfect square just, and is highly sensitive, and easy operating avoids two opening to get into next procedure, improves the quality of products.Fig. 1 is a structural representation of the present invention, and it is A-A fragmentary cross-sectional views among Fig. 1 that inductive type proximity transducer 1, plunger 2, spring perch 3, transfer roller 4, spring set pin 5, stage clip 6, adapter plate 7, swing arm 8, bearing pin 9, roller shaft 10, roller 11, back-up ring 12 Fig. 2 are wherein arranged

Embodiment of the present invention are following, and transfer roller 4 rotates and drives rollers 11 and rotate, when two or plurality of sheets of paper are come; Roller 11 moves up for the center of circle along bearing pin 9; Drive swing arm 8 adjusted screws to proximity transducer 1 near, proximity transducer 1 sends signal instruction and shuts down when detecting set screw, avoid two opening to get into next procedures; Roller 11 is pressed in transfer roller 4 upward pressures has stage clip 6 to regulate; Spring perch 3 is equipped with plunger 2 and moves and promptly adjust roller 11 pressure sizes, roller shaft 10 and bearing pin 9 and sensor 1 distance, general ratio about 1: 5.

Claims (3)

1. the two control setups of opening of defeated paper are made up of inductive type proximity transducer 1, plunger 2, spring perch 3, transfer roller 4, spring set pin 5, stage clip 6, adapter plate 7, swing arm 8, bearing pin 9, roller shaft 10, roller 11, back-up ring 12; It is characterized in that swing arm 8 is installed on the adapter plate 7 through bearing pin 9; And along bearing pin 9 swings; Roller 11 is through roller shaft 10, and back-up ring 12 is fixed in the swing arm 8, and roller 11 rotates under transfer roller 4 drives.

2. it is characterized in that according to the two control setups of opening of the said defeated paper of claim 1: plunger 2 is installed in the spring perch 3, through screw adjusted stage clip 6 pressure, i.e. and roller 11 pressure, inductive type proximity transducer 1 is installed on the adapter plate 7, detects swing arm 8 swinging distances.

3. it is characterized in that according to the two control setups of opening of the said defeated paper of claim 1: roller shaft 10 and bearing pin 9 distances are because of greater than bearing pin 9 and sensor 1 distance, general ratio about 1: 5.
