Description

The pump rod detent mechanism

Technical field

The utility model relates to a kind of pump rod detent mechanism that is used for the pump cap rotating machine, belongs to the package packing machine field.

Background technology

At present; In industries such as daily use chemicals, food, medicine, plastic hose and material that the pump rod on the pump cover is normally elongated are yielding, thus in producing through regular meeting's generating pump rod bending; Pump rod can't insert the phenomenon of bottleneck smoothly, and this phenomenon has seriously hindered the carrying out of pump cap rotating machine spiral cover operation.Also exist in a large number under the prior art and adopt the artificial erection work of accomplishing the pump rod on the pump cover, such manual operation not only labour intensity is big, takes time and effort, and production efficiency is low, also can't adapt to automation, requirement of massive production.The pump rod detent mechanism that the pump cap rotating machine is also arranged on the market, but these pump rod detent mechanism stability and poor reliability influence the completion of pump cap rotating machine subsequent processing sometimes.

Summary of the invention

The purpose of the utility model is the defective that overcomes prior art, provide a kind of simple in structure, cost is low, can be reliablely and stablely carry out the pump rod detent mechanism of correcting location to pump rod.

The technical scheme that realizes the utility model purpose is: a kind of pump rod detent mechanism; It comprises main shaft and rotatably is sleeved on the installation wheel on the main shaft; The pump rod adapter plate that also comprises contiguous block, is sleeved on cam and the pump rod bayonet socket on the main shaft and matches with the pump rod bayonet socket is installed on the wheel and is fixedly connected with shaft seat, and an end of contiguous block is set with along the rolling body of cam cylindrical rolling; The other end is set with rotating shaft; Should go up rotating shaft and can be rotated to support on the shaft seat, the other end of last rotating shaft is connected with lower rotary shaft removably, and described pump rod bayonet socket is fixedly connected on the other end of lower rotary shaft.

Further, through the extension spring fixed link that has been threaded, install on the wheel extension spring bar is installed on the described contiguous block, the extension spring bar is connected through extension spring with the extension spring fixed link.

Further, described rolling body is an outer ring and roll assembly.

After having adopted technique scheme, main shaft is fixed, wheel is installed is rotated around main shaft; Last shaft seat is just and then done the circular movement around main shaft together, thereby the drive rolling body rolls along the cam cylindrical, converts the curvilinear motion of rolling body into rotating shaft self rotatablely move; Thereby driving lower rotary shaft rotates; The pump rod bayonet socket that is fixed on the lower rotary shaft lower end also and then rotates, and when arriving certain position, pump rod bayonet socket and pump rod adapter plate clamp pump rod and be situated between; Avoided occurring pump rod and tilted to insert the phenomenon of bottleneck, thereby realized reliablely and stablely pump rod being carried out the correcting location; After bottleneck was inserted in the bottom of pump rod, the pump rod bayonet socket just in time turned to the position of another setting, and pump rod bayonet socket and the pump rod adapter plate of this moment slowly separate; Thereby accomplished the whole process of pump rod location; And the utility model is simple in structure, and low cost of manufacture is convenient to produce and is implemented; In addition, on contiguous block, can fix an extension spring fixed link, install on the wheel and refill an extension spring bar; And connect extension spring fixed link and extension spring bar through extension spring; Like this, the outer round surface of the periphery of rolling body and cam is adjacent to, and makes pump rod more reliably by correcting.

The specific embodiment

For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,

Shown in Fig. 1 ~ 3; A kind of pump rod detent mechanism, it comprises main shaft 10 and rotatably is sleeved on the installation wheel 11 on the main shaft 10, the pump rod adapter plate 12 that also comprises contiguous block 1, is sleeved on cam 8 and the pump rod bayonet socket 5 on the main shaft 10 and matches with pump rod bayonet socket 5; Install on the wheel 11 and be fixedly connected with shaft seat 3; One end of contiguous block 1 is set with the rolling body 6 that rolls along cam 8 cylindricals, and the other end is set with rotating shaft 2, and rotating shaft 2 can be rotated to support on the shaft seat 3 on this; The other end of last rotating shaft 2 is connected with lower rotary shaft 4 removably, and described pump rod bayonet socket 5 is fixedly connected on the other end of lower rotary shaft 4.

As shown in Figure 1, through the extension spring fixed link 7 that has been threaded, to install on the wheel 11 extension spring bar 9 is installed on the contiguous block 1, extension spring bar 9 is connected through extension spring 13 with extension spring fixed link 7.

As shown in Figure 3, rolling body 6 is an outer ring and roll assembly.Rolling body 6 also can be other bearings, perhaps with the similar part of bearing arrangement.

The principle of work of the utility model is following:

Main shaft 10 is fixed, wheel 11 is installed is rotated around main shaft 10, and last shaft seat 3 is just and then done the circular movement around main shaft 10 together; Thereby driving rolling body 6 rolls along cam 8 cylindricals; Convert the curvilinear motion of rolling body 6 into rotating shaft 2 self rotatablely move, rotate thereby drive lower rotary shaft 4, the pump rod bayonet socket 5 that is fixed on lower rotary shaft 4 lower ends also and then rotates; When arriving certain position; Pump rod bayonet socket 5 clamps pump rod with pump rod adapter plate 12 and is situated between, and has avoided occurring pump rod and has tilted can't insert the phenomenon of bottleneck, thereby realized reliablely and stablely pump rod being carried out the correcting location; After bottleneck was inserted in the bottom of pump rod, pump rod bayonet socket 5 just in time turned to the position of another setting, and pump rod bayonet socket 5 and the pump rod adapter plate 12 of this moment slowly separate; Thereby accomplished the whole process of pump rod location; And the utility model is simple in structure, and low cost of manufacture is convenient to produce and is implemented; In addition, on contiguous block 1, can fix an extension spring fixed link 7, install on the wheel 11 and refill an extension spring bar 9; And connect extension spring fixed link 7 and extension spring bar 9 through extension spring 13; Like this, the outer round surface of the periphery of rolling body 6 and cam 8 is adjacent to, and makes pump rod more reliably by correcting.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
