Clamping jaw-type bottle clamping device with positioning function

Abstract

The invention discloses a clamping jaw-type bottle clamping device with a positioning function. The device comprises a base at the lower end and a clamping jaw at the upper end, wherein the clamping jaw comprises a rotatable outer sleeve vertically arranged in a bearing seat; the upper end of the outer sleeve is coaxially connected with a driving wheel; a pull rod capable of lifting up and down isarranged in the outer sleeve; the lower end of the pull rod extends out from the outer sleeve and is provided with a pressing head; a clamping jaw arm is annularly hinged on the lower end of the outer sleeve; a guide groove is arranged in the clamping jaw arm; a cross bar is arranged on the pull rod; and a pin shaft is arranged on the cross bar and movably arranged in the guide groove. The devicedisclosed by the invention has the advantages that the advantages of a conventional base-type bottle clamping device and a conventional clamping jaw-type bottle clamping device are integrated; the coaxiality of a medicine bottle is guaranteed by utilizing the positioning of the base and the pressing head and the medicine bottle is clamped through the clamping jaw and rotating power is provided torotate the medicine bottle at the same time; and through the bottle clamping mode, the problems of the conventional base-type bottle clamping device, that the driving power is arranged below the baseand the installation and the maintenance are inconvenient and the problems of the conventional clamping jaw-type bottle clamping device, that the coaxiality is not good and centrifugal force and airbubbles are generated during bottle rotating, are solved.

Description

technical field [0001] The invention relates to the pharmaceutical machinery industry, in particular to a claw-type bottle clamping device with a positioning function. Background technique [0002] In the technological process of pharmaceutical production, light inspection is an essential quality inspection link, so light inspection machine is a key equipment in the pharmaceutical industry. At present, there are two types of lamp inspection machines on the market. One is the type with a base. The base is driven by the base to rotate the medicine through friction; the other is the jaw type, the medicine bottle is clamped by the jaw, and the medicine bottle is rotated by driving the jaw. There are certain advantages and disadvantages in the two bottle clamping methods; when the base type is used, the advantage of the rotary bottle type is that the center line of the medicine bottle is coaxial with the rotation axis, and the air bubbles are less; the disadvantage is that the d...

Problems solved by technology

There are certain advantages and disadvantages in the two bottle clamping methods; when the base type is used, the advantage of the rotary bottle type is that the center line of the medicine bottle is coaxial with the rotation axis, and the air bubbles are less; the disadvantage is that the drive needs to be installed under the base, and the power The installation and maintenance of the device are difficult; the advantage of the claw type is that the power is installed on the top, which is convenient for maintenance, and there is no base, which is convenient for maintenance and cleaning; the disadvantage is that when clamping the medicine bottle, it is easy to pinch, which makes the medicine bottle different from the rotation axis Shaft, which produces a large centrifugal force and a large number of air bubbles; there are also some improved types in the industry, such as adding a pressure head to the jaw, and the pressure head presses the medicine bottle while the jaw grabs the medicine bottle; but the light inspection machine detects There is only one meshing point between the large plate and the bottle feeding device (the light inspection machine detects the tangent point between the large plate and the bottle feeding device), and only when the medicine bottle reaches the meshing point, the action of pressing down the pressure head and clamping the jaws is completed, but in fact , it is required to complete the whole set of actions of pressing down the pressure head and clamping the bottle at one time point, which is difficult to realize; in actual work, the time point of clamping the medicine bottle is either advanced or delayed, resulting in most medicine bottles being crooked , when the medicine bottle is rotated, the liquid medicine produces a large number of bubbles and a large centrifugal force
