Description

Automatic machine for closing envelop

The utility model relates to a kind of device that is coated with envelope letter sack.

Traditional envelope flap work mainly is manual operations, and it is low that a large amount of mails are sealed efficient, easily stains clothing again; Also have and use the drum-type glue spreader, though gluing is convenient, seals still and finished by manual, particularly cylinder for a long time contacts with air, and gelling, dry and hard phenomenon are serious, and use is inconvenient.

The purpose of this utility model is to design a kind of energy automatic glue application, and crimping is sealed, and is suitable for many specifications envelope, the automatic envelope sealing machine of sack.

In order to finish above-mentioned task, designed by relay, the automatic control system that travel switch, diode, electromagnet, motor are formed, control gluing and crimping are partly worked.Coaster is set in the body, and the wheel and rack of coaster motor meshes and makes level to moving with coaster along slide bar, and the glue pipe that is provided with on the coaster is communicated with the glue pump, and an electromagnet L is arranged at sebific duct (14) bottom ₁Being contact with sebific duct is connected, between the platen gear of body both sides the crimping plate is housed, the crimping plate is contained in the gear ring and on its diameter line, cooperate drive crimping plate to make 180 ° of flip-flop movements with platen gear by the crimping motor gear, the base plate that parallels with the crimping plate is located on the body base, this base plate is positioned at the position that can carry out the gluing crimping, treats casually to send into the base plate place and accepts to be coated with envelope.Be arranged on the travel switch K at glue spraying head position ₁Connect relay J ₁, K ₃Meet J ₂, by travel switch K ₃And J ₁Control J ₂, J ₁And J ₂Be alternately adhesive and release, realize that spray glue and crimping hocket; Diode D ₃, D ₁, D ₂Meet glue pump motor, electromagnet L respectively ₁And L ₂, travel switch K ₄, K ₂Connect crimping motor and driving motor respectively.

The utlity model has following advantage:

1, simple in structure, stability and adaptability are good, can not be convenient in the post office because of long-term the placement influences use, and public places such as office use;

2, automaticity height, Push switch can be finished the envelope work that is coated with.

Doing one below by accompanying drawing in conjunction with the utility model specific embodiment describes.

Fig. 1 is the utility model complete machine schematic diagram.

Fig. 2 is the utility model side view.

Fig. 3 is the control circuit schematic diagram.

Referring to Fig. 1 Fig. 2, this machine is made up of gluing, crimping and control three parts, the gluing part is made up of with the glue pump and the glue pump motor (1) that are arranged among the body A driving mechanism B, and driving mechanism B is by driving motor (11), tooth bar (10), sebific duct (14), slide bar (12), electromagnet L ₁Form, the body top is parallel to tooth bar (10) and slide bar (12) are housed, and has the jigger top loading of driving motor (11), and driving gear (13) and tooth bar (10) engagement move coaster as horizontal direction on tooth bar and slide bar.Glue pipe (14) is housed on the coaster, and glue pipe (14) one ends are connected with the gum outlet of glue pump, and the other end connects glue spraying head (7), between glue pipe (14) and the coaster electromagnet L is housed ₁, glue pipe (14) and electromagnet L ₁For contact connects, rise and fall in order to attract the glue pipe, the glue pipe extends to base plate (4) gluing position along coaster framework (15), and glue spraying head (7) position is provided with travel switch K ₁, make the relay J of controlling coating system ₁Automatic shutter, control driving motor steering is provided with K in body one side ₂, be parked on the assigned address with the control driving.According to the envelope flap width, glue spraying head (7) has a plurality of glue hole, for preventing glue water clock after hours, parks at coaster on the relevant position of a side base plate 4 and is provided with Capsule (8).

The crimping part is mainly by platen gear (3), crimping motor (2), crimping plate (9), base plate (4) and electromagnet L ₂Form, the body both sides are provided with platen gear (3), crimping plate (9) is housed between two-wheeled (3), pressing plate (9) is contained in gear (3) circle, and crimping plate (9) is remained on the diameter line of platen gear (3), and the gear (6) on the crimping motor (2) is meshed with gear (3), make crimping plate (9) make 180 ° of flip-flop movements by motor (2) driven gear (3), base plate (4) is located on the body base, and is in parallel when quitting work at crimping plate (9), K ₃Be contained on the base plate (4), when the crimping plate contacts with base plate, trigger K ₃With relay J ₂Connect, make the reposition when motor reverses of crimping plate; When the crimping plate is parallel with base plate, promptly touch travel switch K ₄Closure, crimping motor (2) quits work, crimping plate (9) stop motion, electromagnet L ₂Be positioned at base plate (4) bottom, when the crimping plate moves, electromagnet L ₂Produce magnetic field, attract pressing plate (9) casually to compress.

See Fig. 3, K is a power control switch, K ₁Control relay J ₁Work, relay J ₁During adhesive, J ₂Discharge K ₃Control relay J ₂And motor (2), make the reposition of crimping plate, K ₂And K ₄Be protection travel switch, K ₂The control coaster is parked on the assigned address K ₄Then guarantee to quit work diode D after the crimping plate reaches assigned address ₃Assurance glue pump motor (1) is not worked D when driving is returned ₁, D ₂Meet electromagnet L respectively ₁, L ₂Make work of electromagnet.

This machine course of work is as follows: after will mail be sealed delivering to assigned address, and starting switch K, at this moment relay J ₁Adhesive, diode D ₃Conducting, glue pump motor (1) starts, and the motor (11) of driving a vehicle this moment begins to travel forward with tooth bar (10) engagement, when glue spraying head 7 reaches the envelope flap edge, travel switch K ₁Contact enters in the sliding cutter groove (5) and makes travel switch K ₁Circuit disconnects, relay J ₁Discharge diode D ₁Conducting, electromagnet L ₁Begin energising, inhale moving spray sebific duct (14) glue head (7) and travel switch are lifted, motor 11 counter-rotatings of driving a vehicle simultaneously drive the coaster correcting action, trigger travel switch K ₂, the coaster outage, glue spraying head falls, travel switch K ₁Connect, at this moment be in the preparation work state.At this moment, J ₁Discharge J ₂Adhesive, crimping motor (2) just changes, and drives crimping plate (9) by gear (3) and rotates, simultaneously D ₂Conducting, electromagnet L ₂Produce high-intensity magnetic field, inhaling dynamic pressure plate (9) will casually compress, thereby finish casually crimping and L ₂The electromagnet power-assisted compresses, and when pressing plate contacts with base plate, triggers travel switch K ₃, relay J ₂Discharge, normally-closed contact is connected, diode D ₂End electromagnet L ₂Outage, crimping motor (2) counter-rotating, the reposition under platen gear drives of crimping plate touches travel switch K ₄After, motor 2 stalls, crimping partly is in the fully state that gives, and during Push switch K, will repeat the above-mentioned course of work again.
