Abstract
A slurry filling mechanism comprises a charging basket, a spray-head, a piston cylinder (2), a piston (7), a piston rod (5), a charging and discharging reversing valve comprising a metallic valve core (9) and a metallic valve body (3), and a rocker (11) and a connecting bar (12) which are used for reversing valve. Severe abrasions between the piston cylinder and the piston and among the charging and discharging reversing valve components in the prior filling mechanism are changed by that a piston packing ring (6) is arranged on the piston (7) and a valve core packing ring (8) and a valve core packing ring (10) are arranged on the two sides of the metallic valve core (9) in the charging and discharging reversing valve. The filling effects and the reliability are ensured, at the same time the operating lives of the components are better prolonged. The structure is simple and the economical and the practical effects are achieved.
Description
Technical field
The utility model relates to a kind of filling apparatus that is applicable to fields such as food, pharmacy, be specifically related to a kind of slurry filling mechanism.
Background technology
At present, generally all adopt the positive displacement filling mechanism to finish for the thickness slurry of viscosity height, flowing power difference or the can of liquid, wherein a class positive displacement filling mechanism is the piston pump that is made of piston cylinder, piston, a piston rod, with a two-bit triplet input and output material change-over valve that is made of cock spool, valve seat, and the rocker-arm link of open and close valve is formed.A pouring process of said filling mechanism is that one of mobile and the spool that once come and go of piston back and forth rotates, and piston and spool are very frequent with the friction of piston cylinder and valve seat respectively.And said piston is one whole to be the bowl of rubber, not only with metallo-piston cylinder serious wear but also yielding upset in slurry environment, thereby influences the stock quality and the accuracy of measuring; Said spool is that an integral body is the metallo-Rotary-table, tightly require the working accuracy of spool, valve seat higher for airtight, and the reciprocal friction of two metal partss not only can make somewhere wearing and tearing especially severe and cause leakage but also both to kill easily at work.In a word, this structure is easy to make between piston and piston cylinder and the severe wear between spool and valve body, thereby causes slurry to leak and other problems, has shortened its work life greatly.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of slurry filling mechanism, this filling mechanism can not only guarantee the reliability of can, can also reduce wearing and tearing and damage between piston cylinder and piston space and input and output material change-over valve parts simultaneously, prolongs their work life.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of slurry filling mechanism, the rocking arm and the connecting rod of input and output material change-over valve of forming by the piston pump that constitutes by piston cylinder, piston, piston rod, by spool and valve body and control cock commutation, wherein piston be by metal cartridge and on the cylinder of this metal cartridge added obturator piston ring constitute, spool constitutes with the added seal spool ring in round metal stage body and two ends thereof in the input and output material change-over valve.In pouring process; metallic piston supports seal ring to contact between obturator piston ring and piston cylinder during piston round mobile; avoided the undue wear that produces between whole softer rubber piston distortion and cylinder body, same when metal spool is done two commutation actions in the input and output material change-over valve seal spool ring at metal spool two ends make spool avoid making direct contact with valve body and played the effect of protection metal spool and metal valve body.
The beneficial effects of the utility model are: changed the situation of serious wear between the piston cylinder of original filling mechanism and piston space and input and output material change-over valve parts, when guaranteeing can effect and reliability, prolonged their work life better.When obturator piston ring or valve core seal ring damage, only adopt replacing obturator piston ring or valve core seal ring just can rework simultaneously, reduced the service expenditure of equipment, simple in structure, economical and practical.
Description of drawings
Accompanying drawing 1 is a main TV structure scheme drawing of the present utility model;
Accompanying drawing 2 is plan structure scheme drawings of the present utility model.
Among the figure: 1. charging basket, 2. piston cylinder, 3. metal valve body, 4. shower nozzle, 5. piston rod, 6. obturator piston ring, 7. piston, 8. seal spool ring, 9. metal spool, 10. seal spool ring, 11. rocking arms, 12. connecting rods.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
Shown in accompanying drawing 1,2, the utility model is to be provided with the piston (7) that links with piston rod (5) in piston cylinder (2), be added with obturator piston ring (6) on the piston (7), the import and export of piston cylinder (2) are connected with the normal opening of a two-bit triplet input and output material change-over valve of being made up of metal valve body (3) and metal spool (9) and two ends seal spool rings (8) thereof, (10), connect a charging basket (1) and a shower nozzle (4) respectively on other two interfaces of this input and output material change-over valve, the input and output material change-over valve is by rocking arm (11) and connecting rod (12) control action.
When piston (7) is back mobile; the metal spool (9) of rocking arm (11) and connecting rod (12) control input and output material change-over valve is communicated with charging basket (1) and piston cylinder (2); make material enter into piston cylinder (2) from charging basket (1); then piston (7) moves forward; the metal spool (9) of rocking arm (11) and connecting rod (12) control input and output material change-over valve is communicated with piston cylinder (2) and shower nozzle (4), and material is filled in the container by shower nozzle (4) from piston cylinder (2).
In Fig. 1,2, obturator piston ring (6) can adopt y-type seal ring, the O RunddichtringO can be adopted in seal spool ring (8), (10), comes and goes the direct wearing and tearing of having avoided reaching between piston cylinder (2) and piston (7) in mobile and metal spool (9) commutation between metal valve body (3) and metal spool (9) at piston (7).The material of obturator piston ring is used PVC especially earlier, and is promptly nontoxic not yielding and economical again, and the material of seal spool ring adopts oil proof rubber or polyurethane, thereby prolonged service life more, reaches economical and practical effect.
Claims (4)
1, a kind of slurry filling mechanism, the rocking arm and the connecting rod of input and output material change-over valve of forming by the piston pump that constitutes by piston cylinder, piston, piston rod, by spool and valve body and control cock commutation, it is characterized in that piston be by metal cartridge and on the cylinder of this metal cartridge added obturator piston ring constitute, spool constitutes with the added seal spool ring in round metal stage body and two ends thereof in the input and output material change-over valve.
