CN2348939Y - Automatic gum coater - Google Patents

Abstract

The utility model relates to an automatic gum coater, which uses light and electricity to control a motor to drive an operating mechanism. An eccentric link mechanism is adopted to make a gum coating plunger piston reciprocating movement. The other end of the gum coating plunger piston extends into a gum mouth, wherein, the inner cavity of the gum mouth is connected with a gum barrel; gum solution in the inner cavity of the gum mouth is pushed out of the gum mouth by the gum coating plunger piston in the reciprocating movement, and is coated on paper surface required to be pasted. The motor for driving a gum coating mechanism to work automatically controls to rotate in light and electricity mode. When a gum coating paper piece is sent to a gum coating position on a worktable, the motor rotates; the gum coating begins. When the paper piece finishes coating gum and leaves the gum coating position, the motor stops to rotate; the gum coating stops.

Description

Automatic glue spreaders

At present, when the paper bag of needs stickup envelope such as the post and telecommunications office of China's wide geographic area, institute, office and class likelihood envelope and paper, all be to adopt manual applied paste and glue, promptly unhygienic, also influence the cleaning of environment, efficient is low again.Present some post and telecommunications office, a kind of glue spreading apparatus that used, that is to adorn some rollers on a glue case, and the Lower Half of roller immerses glue, and rotation roller is brought glue up, is used for pasting envelope.This also is a kind of progress, but at health, clean environment, increase work efficiency on, improve little.It is said that external and domestic minority classification envelope (as Express Mail Service) carries glue, but extensively various envelopes (paper bag) are carried out carrying the glue technology in China, also very difficult.

The purpose of this utility model provides a kind of automatic glue spreaders that can carry out automatic glue application on the envelope (paper) that needs are pasted.

The utility model uses health (hand does not contact glue), can keep the environment cleaning, improves sticking efficiency (an envelope ordinary envelope capable gluing only needs 4 seconds).

The purpose of this utility model is achieved in that in shell with a support motor, rubber-coated mechanism, control circuit board, glue bucket link together, when motor is passed to eccentric wheel in the rubber-coated mechanism to moment, drive gluing plunger (hereinafter referred plunger) by connecting elements and move back and forth.Plunger is when upwards move in the summit, the glue mouth oral area that is connected with the glue bucket is opened, the inner chamber glue flows to oral area under the gravity effect, when plunger moves downward, push away glue discharging mouth flowing to glue mouth oral area glue, until following summit, pushing tow just is coated on the paper of putting into the gluing position at the glue of plunger end like this.The following summit that plunger motion arrives is the gluing position, also is the stop position that each gluing finishes, at this moment; plunger stops up Jiao Zuikou, makes inside and outside completely cutting off, and stops the glue outflow, keeps the clean health of glue mouth oral area; also avoid glue to flow out, drying is condensed, to guarantee next operate as normal.

The utility model is simple in structure, and is durable, easy to maintenance, is applicable to weather, the temperature (China south, the north, winter, summer) of different regions.Volume is little, and cost is low, extensively can be used for big or small post and telecommunications office, encapsulates the more newspaper office of mail, information departments, general office etc. in one's power.

Below in conjunction with accompanying drawing, the utility model is further specified (selecting the automatic glue spreaders that is designed to a gluing plunger for use is embodiment):

Fig. 1 is a section of structure of the present utility model, also is the location drawing that the vertex position gluing stops up Jiao Zuikou simultaneously under the paster plug place.

Fig. 2 is a vertex position in the gluing plunger place, the location drawing that glue flows to glue mouth oral area.

Fig. 3 is the control circuit schematic diagram.

Among Fig. 1 and Fig. 2: motor (1), connecting rod (2), line shaft (3), eccentric wheel (4), bearing (5), ship and resell on another market spool (6), guide pillar (7), double-screw bolt (8), spring (9), gluing plunger (10), " O " RunddichtringO (11), Jiao Zui (forming) (12) by two, one group of photoelectric tube (the corresponding photodiode of light emitting diode) (13), one group of photoelectric tube (14), body (15), one group of photoelectric tube (16), support (17), glue (the common glue of generally selling on the market) (18), glue bucket (19), glue pipeline (20), workbench (21), surplus glue box (22).

Among Fig. 1 and Fig. 2: motor (1) is passed to eccentric wheel (4) to moment, eccentric wheel drivening rod (2), guide shaft (7) the gluing plunger (10) that is contained in the connecting rod other end is pumped, gluing plunger lower end is stretched among the Jiao Zui (12), when in Fig. 1 position, the conus portion of plunger lower end and glue mouth inner chamber lower cone are coincide, inside and outside isolated, stop the glue outflow, when the gluing plunger moves upward, open glue mouth oral area, glue flows to glue mouth oral area, when plunger moves downward again, promptly the glue that flows in the oral area conical cavity is pushed away glue discharging mouth.When plunger is walked to following summit, pushing tow is coated on the paper of sending into gluing position (be Jiao Zui over against workbench above) at the glue of stopper head end.So Fig. 1 is the gluing position, also be each plunger when moving upward, promptly bring portion of air into and enter Jiao Zui, and float over the top of glue mouth inner chamber very soon.Because the difference of air and glue proportion, along floating over glue pipeline (20) the inner chamber top that glue mouth inner chamber links to each other with inner chamber, the anti-glue bucket (19) that flows into replenishes the space that loses glue in the bucket at the part air.Spring (9) effect is when axle plug gluing is run into thicker gluing spare, is unlikely stuck or crowded bad gluing spare.Sealing ring (11) is to stop because pressure effect or plunger motion band glue enter body (15) inside.Surplus liquid basin (22) is when collecting gluing spare and offing normal, and is coated with empty glue.As shown, 3 groups of photoelectric tubes (13,14,16) are housed in the machine, be in when treating duty (both control circuit connection power supplys) at the utility model, when hold gluing spare from a left side or the right side enter the gluing position along workbench (21) plane, one of them is blocked photoelectric tube (13,14), motor rotates, rubber-coated mechanism begins gluing, when the whole disengagings of two photoelectric tubes (13,14) are blocked, this group of photoelectric tube (16) must align (both do not had between this group photodiode and the light emitting diode and blocked), motor side stops, and is parked in down the summit to guarantee the gluing plunger.The signal that photoelectric tube (13,14) receives blocks for gluing spare enters blocking with the removal of gluing spare disengaging gluing position of gluing position.The signal that photoelectric tube (16) receives is that the aperture on the eccentric wheel aligns in this group photoelectric tube or misplaces, and also is not block and block.Control circuit controls delicately that motor rotates and stop position accurately.

Claims (1)

1. A kind of automatic glue spreaders is characterized in that: adorn rolling bearing, connecting rod on motor-operated eccentric wheel, connecting rod connects guide pillar, the other end of the guide pillar gluing plunger of packing into, the gluing plunger Jiao Zui that packs into.
