Abstract
The utility model discloses a kneader cylinder with buffer structure which includes a cylinder body (1), a cylinder rod (2) arranged in the cylinder body (1), a piston (3) arranged on the cylinder rod (2) and being capable of moving along the axial direction of the cylinder body (1), and a cylinder head (4) arranged at the two axial ends and matched with the piston (3). The kneader cylinder with buffer structure is characterized in that the upper and the lower sides of the piston (3) are respectively equipped with cushion collars (5) the shape of which matches that of a cushion chamber (6) on the cylinder head (4), the cushion chamber (6) is connected to a ventilation passage (7) which as well is connected to the cylinder body (1) through an auxiliary ventilation passage (8), and an adjusting valve (9) is arranged at the exit of the ventilation passage (7). The kneader cylinder with buffer structure has the advantages of simple structure, ingenious design, rational arrangement and prolonged useful life and maintenance period.
Description
Technical field
The utility model relates to a kind of cylinder, particularly a kind of masticator cylinder with the buffer protection structure.
Background technique
Cylinder is that compressed-air actuated pressure energy is converted to mechanical energy, and driving mechanism is done the mechanism of straight reciprocating motion.In industrial production, obtain a wide range of applications, traditional cylinder piston is constantly made reciprocal straight line motion in cylinder interior under the promotion of gas, survey and bump back and forth with in the cylinder cap, first can produce certain noise, the second this collision belongs to the rigidity contact more, have a strong impact on sealability and the working life of piston, improved the maintenance rate of cylinder.Employed cylinder in the masticator structure particularly, this kind problem is more serious, therefore needs now a kind of novel masticator cylinder that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, propose a kind of simple in structure, design ingenious, rationally distributed, the masticator cylinder with buffer structure that working life and maintenance period can both prolong.
Technical solution of the present utility model is: a kind of masticator cylinder with buffer structure, comprise cylinder body 1, be provided with piston rod 2 in the cylinder body 1, being provided with on the piston rod 2 can be along the piston 3 of cylinder body 1 axial motion, and the axial two ends of cylinder body 1 are provided with the cylinder cap 4 that matches with piston 3.It is characterized in that: the up and down both sides of described piston 3 are respectively arranged with cushion collar 5, and the buffer cavity 6 on the shape of cushion collar 5 and the cylinder cap 4 matches, buffer cavity 6 communicates with scavenge duct 7, scavenge duct 7 also is communicated with cylinder body 1 inner chamber by secondary scavenge duct 8, also is provided with modulating valve 9 in the outlet port of scavenge duct 7.
The utility model is compared with prior art, has following advantage:
The masticator cylinder with buffer structure of this kind of structural type, it is simple in structure, design ingenious, rationally distributed, it is for constantly with the cylinder cap inboard rigid collision occuring in traditional masticator cylinder piston movement process, cause the piston airtight performance to descend, even the piston problem such as be damaged, design buffer cavity in the cylinder cap inboard and with the scavenge duct of modulating valve, and correspondingly design the cushion collar that matches with buffer cavity at piston, piston is at the end of motion like this, the gas that needs at first will remain in the cylinder body is extruded, can contact with cylinder cap, delay the speed of masticator cylinder and cylinder cap Contact, prevent the damage of piston or masticator cylinder interior part.And the preparation process of this structure is simple, and is cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the A section enlarged view of Fig. 1.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2: a kind of masticator cylinder with buffer structure, comprise cylinder body 1, in cylinder body 1, be provided with piston rod 2, be provided with the piston 3 that can move along the axial direction of cylinder body 1 on the piston rod 2, the axial two ends of cylinder body 1 are provided with the cylinder cap 4 that matches with piston 3, the center of cylinder cap 4 is provided with buffer cavity 6, and it is connected with the scavenge duct 7 that exhaust is used;
Up and down both sides at piston 3 are respectively arranged with cushion collar 5, cushion collar 5 matches with shape, the size of buffer cavity 6, buffer cavity 6 is connected with scavenge duct 7 in being arranged on cylinder cap 4, scavenge duct 7 also communicates by secondary scavenge duct 8 with the inner chamber of cylinder body 1, is provided with modulating valve 9 in the outlet port of scavenge duct 7.
The utility model embodiment's the working procedure with the masticator cylinder of buffer structure is as follows: piston 2 under the drive of piston rod 2 in the process of the axially reciprocating of cylinder body 1, piston 2 is near in the process of cylinder cap 4, gas between piston 2 and the cylinder cap 4 is compressed, and by buffer cavity 6 and scavenge duct 7 discharges, owing to be provided with the cushion collar 5 that matches with buffer cavity 6 volumes at piston 2, therefore exhaust process meeting Exhaust Gas as much as possible prolongs period of exhaust; Also can enter in the scavenge duct 7 by secondary scavenge duct 8 by some gas simultaneously; And the modulating valve 9 that is arranged on scavenge duct 7 outlet ports can determine the size of air displacement in the unit time, thereby controls period of exhaust, reaches the purpose of the movement velocity of slowing down piston 2 and cylinder cap 4 Contacts.
Claims (1)
