The automatic cap pulling device has the advantages that the structure is simple and reasonable, the cap 202 of the tubular container 201 is automatically pulled out, the manual cap pulling mode is replaced, manual force pulling by an operator is not needed, the labor intensity is greatly reduced, cap pulling operation is simpler and quicker, time and labor are saved, the operation efficiency is greatly improved, the fatigue condition of the operator can not occur even if long-time operation is performed, and the cap pulling efficiency is greatly improved. Meanwhile, the hands of the operators are prevented from directly contacting the tubular container 201 and the pipe cap 202 thereof, and the situations that the hands of the operators are scratched and the tubular container 201 and the pipe cap 202 thereof are polluted can be avoided.

The specific structure of the biosafety cabinet 30 is a conventional technical means well known to those skilled in the art, and thus will not be described in detail herein. Specifically, the following are:

In detail, the lifting mounting plate 61 moves vertically on the frame 10, the lifting driving mechanism 62 is disposed on the frame 10, and the lifting mounting plate 61 is in transmission connection with the lifting driving mechanism 62, so that the lifting mounting plate 61 is driven to move up and down in the vertical direction by the lifting driving mechanism 62.

The first rotary driver 63 may be a motor, but not limited to, and the first rotary driver 63 is fixed on the lifting mounting plate 61. Further, the tightening mechanism 64 includes: the fixed mounting cylinder 641, the rotating cylinder 642, the lifting screw 643, the first supporting claw 644, the second supporting claw 645, the first elastic member 646, the limiting wheel 647, the horizontal limiting pin 648a and the second elastic member 648b, the fixed mounting cylinder 641 is vertically fixed on the lifting mounting plate 61, the rotating cylinder 642 is rotatably vertically penetrated in the fixed mounting cylinder 641, and the rotating cylinder 642 is in transmission connection with the output end of the first rotary driver 63; the lifting screw 643 is vertically penetrated in the rotating cylinder 642 in a threaded fit manner, an annular guide part 6422 is formed at the lower end of the outer side wall of the rotating cylinder 642, and the annular guide part 6422 is of a structure gradually expanding from top to bottom; the first tightening jaw 644 and the second tightening jaw 645 are openable and closable and are arranged at the lower end of the lifting screw 643, and when the upper end of the first tightening jaw 644 and the upper end of the second tightening jaw 645 are far away from each other and open, the lower end of the first tightening jaw 644 and the lower end of the second tightening jaw 645 are far away from each other and open so as to be tightly supported in the inner hole of the pipe cap 202. The first elastic member 646 abuts between the first tightening jaw 644 and the second tightening jaw 645, and the first elastic member 646 constantly drives the upper ends of the first tightening jaw 644 and the second tightening jaw 645 to slidably abut against the annular guide portion 6422. When the lifting screw 643 drives the first tightening jaw 644 and the second tightening jaw 645 to descend, the annular guide portion 6422 guides the upper ends of the first tightening jaw 644 and the second tightening jaw 645 to move away from each other so as to drive the lower ends of the first tightening jaw 644 and the second tightening jaw 645 to move away from each other and open so as to be tightly supported in the inner hole 203 of the cap 202. The limiting wheel 647 is fixed at the upper end of the lifting screw 643, a plurality of limiting grooves 6471 are formed on the circumferential side surface of the limiting wheel 647, and the limiting grooves 6471 are uniformly distributed at intervals along the circumferential direction of the limiting wheel 647; the horizontal limit pin 648a moves on the lifting mounting plate 61 along the radial direction of the limit wheel 647, the horizontal limit pin 648a can slide in or out along the circumferential direction of the limit wheel 647 and is clamped in any one of the limit grooves 6471, the second elastic member 648b can be a compression spring, but not limited to this, the second elastic member 648b is abutted between the lifting mounting plate 61 and the horizontal limit pin 648a, and the second elastic member 648b constantly drives the horizontal limit pin 648a to move towards the axial lead of the limit wheel 647.

When it is necessary to remove the cap 202 of the tubular container 201, the lifting mounting plate 61 is driven to move downward in the vertical direction by the lifting driving mechanism 62 so that the lower ends of the closed first and second holding claws 644 and 645 are inserted into the cap 202 on the tubular container 201 clamped by the clamping device 50. The horizontal limiting pin 648a is kept elastically moving and clamped in the opposite limiting groove 6471 under the elastic force of the second elastic piece 648b, and the horizontal limiting pin 648a can stop the rotation of the limiting wheel 647, so as to stop the rotation of the lifting screw 643. Then the first rotary driver 63 drives the rotary cylinder 642 to rotate to drive the lifting screw 643 to move downwards, then the lifting screw 643 drives the first tightening claw 644 and the second tightening claw 645 to move downwards synchronously, the upper end of the first tightening claw 644 and the upper end of the second tightening claw 645 are constantly driven to slide and abut against the annular guide part 6422 by the first elastic piece 646, under the guiding effect of the annular guide part 6422, the upper end of the first tightening claw 644 and the upper end of the second tightening claw 645 are mutually separated to drive the lower end of the first tightening claw 644 and the lower end of the second tightening claw 645 to be mutually separated and opened, further the lower end of the first tightening claw 644 and the lower end of the second tightening claw 645 are tightly supported in the pipe cap 202 of the tubular container 201, and then the lifting driving mechanism 62 drives the lifting mounting plate 61 to move upwards along the vertical direction, so that the tightly supported pipe cap 202 can be pulled out of the tubular container 201.

The horizontal limiting pin 648a is elastically moved by the elastic force of the second elastic member 648b and is engaged with the elastic limiting structure of the opposite limiting groove 6471, so that the lifting screw 643 can only move up and down and cannot rotate together with the rotating cylinder 642. When the lifting screw 643 descends to the lower end of the first tightening jaw 644 and the lower end of the second tightening jaw 645 are away from each other and are stretched and tightened in the pipe cap 202 of the tubular container 201, and the rotating cylinder 642 continues to rotate, the lifting screw 643 continues to have a descending trend, so that the friction force between the annular guide part 6422 and the upper end of the first tightening jaw 644 and the upper end of the second tightening jaw 645 is continuously increased, the continuously increased friction force can enable the rotating force of the first tightening jaw 644 and the second tightening jaw 645 to drive the lifting screw 643 and the limiting wheel 647 to rotate also to be continuously increased until the limiting groove 6471 on the limiting wheel 647 can overcome the elastic clamping of the elastic moving horizontal limiting pin 648a, and the horizontal limiting pin 648a overcomes the elastic acting force of the second elastic piece 648b to retract and slide out of the limiting groove 6471 on the limiting wheel 647, the lifting screw 643 and the limiting wheel 647 can rotate along with the rotating cylinder 642, so that the lower end of the first tightening jaw 644 and the second tightening jaw 645 can be prevented from driving the lifting screw 643 and the lower end of the second tightening jaw 645 to drive the second tightening jaw 645 to rotate together with the pipe cap 202 to move away from the lower end of the tubular container 201, and the tubular container 201 can be easily stretched out, and the tubular container 201 can be more stretched and the tubular container 201 can be more far away from the lower end of the tubular cap 201.

Referring to fig. 7 to 10, the lower end of the rotary cylinder 642 is radially outwardly enlarged to form a spacing head 6421, an annular spacing step 6423 is formed in the spacing head 6421, and an annular guide portion 6422 is formed on the outer side wall of the spacing head 6421; the lower end of the lifting screw 643 expands radially outwards to form a connector 6431, and the connector 6431 moves vertically in the annular limiting step 6423 in a rotatable manner. The vertical moving range of the connector 6431 is limited in the annular limiting step 6423, the lifting screw 643 is prevented from moving upwards excessively vertically, and the structure is simpler and more reasonable.

Furthermore, the first tightening pawl 644 includes a first pivot portion 6441, a first sliding supporting arm 6442 formed by the upward extension of the first pivot portion 6441, and a first tightening arm 6443 formed by the downward extension of the first pivot portion 6441, and the second tightening pawl 645 includes a second pivot portion 6451, a second sliding supporting arm 6452 formed by the upward extension of the second pivot portion 6451, and a second tightening arm 6453 formed by the downward extension of the second pivot portion 6451; the first pivot portion 6441 and the second pivot portion 6451 are pivoted on the connector 6431 around a pivot shaft 6432 disposed at the same level, the first sliding supporting arm 6442 and the first tightening arm 6443 are respectively located at two sides of the pivot shaft 6432, and the second sliding supporting arm 6452 and the second tightening arm 6453 are respectively located at two sides of the pivot shaft 6432. Thereby realizing the structure that the first tightening claw 644 and the second tightening claw 645 are arranged at the lower end of the lifting screw 643 and can be opened and closed, and the structure is simpler and more reasonable.
