Abstract
A kind of gear adhesive dispenser of twin-screw extrusion tablet press, including front barrel and the retaining plate being symmetricly set at left and right sides of front barrel, it is characterized in that: front barrel left and right ends are respectively equipped with the arc-shaped slot with retaining plate cooperation, retaining plate passes through arc-shaped slot respectively and connect with front barrel；It is fixed between front barrel and retaining plate by 1-2 screw.The utility model has the advantages that: by the optimization design of retaining plate, change the force structure of retaining plate, keeps retaining plate installation and replacement simple and convenient；Retaining plate is directly installed in the arc-shaped slot at front barrel both ends, screw only plays fixed function, not by transverse shear stress power, effectively prevent influence of the sizing material to the transverse shear stress power of retaining plate to screw service life when equipment work, retaining plate is caused to be displaced or fall off, the problems such as wearing roller or reducing out tablet quality, extends the service life of retaining plate, to guarantee to design stability in use.
Description
Technical field
The utility model relates to field of rubber machinery, the gear adhesive dispenser of specifically a kind of twin-screw extrusion tablet press.
Background technique
Twin-screw extrusion tablet press gear mucilage binding is set to flow channel type retaining plate, is mounted in twin-screw extrusion tablet press head and goes out
A gear glue component at left and right sides of mouthful, inner arc face maximum gauge are close with screw outlet diameter.Retaining plate makes to squeeze out
The stress space that a relative closure is formed between machine and tablet press machine, when the sizing material of twin-screw extrusion stops through retaining plate, and
Sizing material constantly squeezes, and pressure gradually rises, and the accumulation force of generation keeps sizing material closely knit, and by tablet press machine, roller is rotated up and down at this time,
Using the frictional force wedging sizing material of sizing material and roll surface, and compression moulding film.Retaining plate is among twin-screw extrusion tablet press
One key stressed member.
Traditional twin-screw extrusion tablet press gear adhesive dispenser is independent two parts with fixed front barrel is contacted, each
Retaining plate is fitted in front barrel installation, and single retaining plate is fixed on front barrel, screw orientation and front barrel plastic emitting by 4-6 screw
Direction is parallel.The extruding force of sizing material constantly squeezes retaining plate, the screw of stress when the gear adhesive dispenser of this structure makes equipment work
Time, which has been grown, to be deformed, and so that retaining plate is displaced or is fallen off, thus the gear glue for wearing roller or reducing out tablet quality, and more renew
Device is time-consuming and laborious.
Utility model content
In view of the drawbacks of the prior art, the utility model provides a kind of gear adhesive dispenser of twin-screw extrusion tablet press, should
Device changes the force structure of retaining plate by the optimization design of retaining plate, keeps retaining plate installation and replacement simple and convenient, and extend
The service life of retaining plate.
Realizing the technical solution of the utility model aim is:
A kind of gear adhesive dispenser of twin-screw extrusion tablet press including front barrel and is symmetricly set at left and right sides of front barrel
Retaining plate, unlike the prior art:
Front barrel left and right ends be respectively equipped with retaining plate cooperation arc-shaped slot, retaining plate pass through respectively arc-shaped slot with
Front barrel connection；
It is fixed between the front barrel and retaining plate by 1-2 screw.
The utility model has the advantages that: by the optimization design of retaining plate, changes the force structure of retaining plate, make retaining plate
Installation and replacement are simple and convenient；Retaining plate is directly installed in the arc-shaped slot at front barrel both ends, and screw only plays fixed function, not by
Transverse shear stress power effectively prevents influence of the sizing material to the transverse shear stress power of retaining plate to screw service life when equipment work, causes
The problems such as retaining plate is displaced or falls off, and wears roller or reduces out tablet quality, extends the service life of retaining plate, to guarantee
The stability of design in use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
In figure: 1. front barrel, the 2. right retaining plate of left retaining plate 3..
Specific embodiment
The content of the present invention is further elaborated with reference to the accompanying drawings and examples, but is not to the utility model
Restriction.
Embodiment:
As shown in Figure 1, a kind of gear adhesive dispenser of twin-screw extrusion tablet press of the utility model, by front barrel 1 and symmetrically set
It sets left retaining plate 2, right retaining plate 3 in 1 left and right sides of front barrel to form, the molding of 1 one-step casting of front barrel, front barrel 1 and a left side
The contact slot cooperation processing of retaining plate 2, right retaining plate 3, guarantees that contact surface eliminates gap；1 card slot of front barrel is arranged to arc
Shape is clamped with left retaining plate 2, right retaining plate 3 respectively, guarantees left retaining plate 2 and the clamping of right retaining plate 3 in place, not play.
When equipment works, the extruding force of sizing material presses left and right retaining plate toward both ends, and left and right retaining plate both ends directly contact
Play will not occur for front barrel slot, guarantee that plastic emitting is stablized；1-2 fixation, and screw are only needed between front barrel and retaining plate
Not by transverse shear stress power, when replacement, which need to only unclamp two screws, extracts retaining plate out and replaces, more steady compared with prior art
It is fixed, replace more convenient and quicker.
