Abstract

The utility model provides an automatic cup falling device, which comprises a main body structural part, a cam, a cup hanging hook and a transmission device; wherein, the cup hanging hook is arranged above the cam and is propped against the cam, a leading nut in the transmission device and connected with a lead screw on a fixing motor shaft is embedded in a clipping groove on a sliding plate integrally shaped through injection molding, gear racks at the both sides of the sliding plate are meshed with the gear connected on the cam, a guide groove on the bottom surface at the middle part of the sliding plate is movably connected with a vertical rib at the middle part of the main body structural part in a limiting way, a front position travel switch seat and a rear position travel switch seat which are arranged on the main body structural part are connected with the sliding plate and the motor to form a closed circuit structure, therefore the assembly technological process is simplified, the quantity of the parts is reduced, the problems of the former water dispenser that the action gap between the parts in the structure is large, the parts required to be connected are more, the idle stroke is large, the transmission error is high, the mechanism motion is not reliable because the movement is out of synchronous, the processing and the installation process of the small parts in the original structure are complex, the complete machine cannot work because the parts are easy to fall off after being assembled are solved, and the product quality is improved.

Description

A kind of automatic cup lowering device

Technical field:

The utility model relates to a kind of automatic water-drinking machine, particularly a kind of cup lowering device of automatic water-drinking machine.

Background technology:

The automatic cup lowering device of present automatic water-drinking machine adopts the syndeton of big fork of action gap and crank as drive mechanism more, this transmission mechanism, attaching parts are many, idle running greatly, especially in the moving part of bilaterally symmetric axle, often asynchronous motion, cause mechanism action unreliable, in the past in the structure, riveted is the processing and the mounting process complexity of widget such as pivot pin, fastening pivot pin fixedly in addition, and easily getting loose after the assembling causes complete machine not work.

Summary of the invention:

Goal of the invention: the utility model provides a kind of automatic cup lowering device, and it is big and coupling component is many, idle running is big, driving error is big, moving asynchronously causes widget in the unreliable and original structure of mechanism action to be processed and mounting process complexity, part easily come off after assembling and cause the inoperable problem of complete machine that its purpose has been to solve action gap between the syndeton part of fork and crank in the cup lowering device transmission device in the past.

Technical scheme: the utility model is achieved through the following technical solutions:

A kind of automatic cup lowering device, comprise the body junction member, cam, hang cup hook and transmission device, top and cam that extension cup hook is arranged on cam contact, it is characterized in that: the screw that links to each other with screw mandrel on the fixed electrical machinery axle in the transmission device is embedded in the draw-in groove on the slide plate that integral molded plastic is shaped, the tooth bar of slide plate both sides and the gears engaged that is connected on the cam, movable spacing connection of the vertical rib at the gathering sill of bottom surface and body junction member middle part in the middle part of the slide plate, the anteposition travel switch seat that is arranged on the body junction member is connected slide plate and motor formation closed circuit structure with position, a back travel switch seat.

The both sides of slide plate, the top of tooth bar also are provided with the wing plate that forms whole symmetry with slide plate.

Advantage and effect: the slide plate that has double sided rack that transmission device of the present utility model adopts a motor-operated integral molded plastic to be shaped, meshed transmission gear with two symmetrical distributions, simplified assembling technology procedure to greatest extent, reduced number of spare parts simultaneously, it is big to have solved in the water dispenser structure in the past the action gap between the part well, coupling component is many, idle running is big, driving error is big, asynchronous widget processing and the mounting process complexity that causes in the unreliable and original structure of mechanism action of moving, easily come off after the part assembling and cause the inoperable problem of complete machine, it reduces driving error, has improved product quality.

The specific embodiment:

Embodiment:

A kind of automatic water-drinking machine, comprise body junction member 8, cam 14, hang cup hook 15 and transmission device, top and cam 14 that extension cup hook 15 is arranged on cam contact, it is characterized in that in the transmission device with the fixed electrical machinery axle on the screw 2 that links to each other by threaded engagement of screw mandrel 1 be embedded in the draw-in groove 4 at middle part on the slide plate 3 that integral molded plastic is shaped, lining is coated with pellicle with noise-decreasing between screw 2 and draw-in groove 4, when screw mandrel 1 rotated with fixing axis both forward and reverse directions, screw 2 just promoted slide plate and moves back and forth; The tooth bar 5 of slide plate 3 both sides and gear 6 engagements, gear 6 is connected with the cam 14 of cup lowering device, tooth bar 5 by both sides during slide plate 3 motion promotes the gear 6 that is engaged with and drives cam 14 to do the reciprocal rotation of certain amplitude and finish mechanism's power, the gathering sill 7 of bottom surface, slide plate 3 middle part and movable spacing connection of the vertical rib at body junction member 8 middle parts, play guide effect with screw mandrel 1 axis parallel direction, the top of the both sides of slide plate 3, tooth bar 5 also is provided with the wing plate 10 with 3 one-tenth whole symmetries of slide plate, and wing plate 10 can block gear 6 planes to prevent its axial float.

Anteposition travel switch seat 12 on the body junction member 8 is connected slide plate 3 with position, back travel switch seat 13 and motor forms automatic control circuit, motor is arranged in the motor fixed frame 11 with body junction member 8 integral one-step moldings, when slide plate 3 touching front travel switch bases 12, back travel switch seat 13, by the operation program motion of design, the gear 6 in the transmission device drives cam 14 and hangs 15 work of cup hook and finish a glass process under automatic control circuit control.
