Detailed Description

As shown in fig. 1-3, a cap screwing device includes a housing 1, a clamping arm 2, a top rod 3, a driving wheel 4, a bearing seat 5, a notch 11, a bearing 23, a spring 12, a clamping seat 21, and an anti-skid rubber pad 23. Casing 1 passes through bearing frame 5 fixed mounting on organism 6, and casing 1 is rotatable with bearing frame 5 relatively, and servo motor 7 is connected with the transmission of drive wheel 4 on the casing 1 through the conveyer belt transmission, drives drive wheel 4 through servo motor 7 and rotates, and drive wheel 4 and casing 1 structure as an organic whole drive casing 1 promptly and rotate. Casing 1 is hollow structure, and ejector pin 3 sets up in the cavity of casing 1, and ejector pin 1 can move up and down along the cavity of casing 1, and the upper end and the cylinder 31 transmission of ejector pin 1 are connected, and cylinder 31 fixed mounting is on organism 6, and the lower extreme of ejector pin 1 sets up to the cam surface. Be provided with two breachs 11 that the position corresponds on casing 1's the lower extreme, the top of two breach 11 is provided with respectively has the internal screw thread spring hole, two spring that correspond are empty to be provided with spring 12 respectively, arm lock 2 is two, two arm lock 2 are respectively through bearing 23 swing joint in corresponding breach 11, the upper end of two arm lock 2 all is crooked to casing 1 cavity intracavity, the up end of two arm lock 2 all sets up to the cam surface, the up end of two arm lock 2 conflicts with the cam surface of ejector pin 3 lower extreme respectively. The contact surface of the two clamping arms 2 and the ejector rod 3 is in tangent plane contact through the arrangement of the cam surface, and the friction between the two clamping arms and the ejector rod is greatly reduced. The upper ends of the two clamping arms 2 are provided with slotted holes on the surfaces corresponding to the spring holes, one end of the spring 12 is placed into the slotted holes to be abutted against the clamping arms, the contact surface is stable, and the other end of the spring 12 is bolted into the spring holes with internal threads through bolts to be abutted against the spring. The clip arms 2 can be opened by the elastic force of the spring 12. Outside lower extreme extension of arm lock 2 extended to breach 11, the lower extreme fixedly connected with holder 21 of arm lock 2, the fixed anti-skidding rubber pad 22 that is provided with on holder 21, skid and cause the damage to the lid surface when the effectual tight lid of holder clamp that prevents presss from both sides.

During the specific use, earlier promote ejector pin 3 downwards through cylinder 31, the cam surface of ejector pin 3 moves down, arm lock 2 promotes the upper end of arm lock 2 downwards through spring 12's elasticity, arm lock 2 uses bearing 23 to rotate as the center, realizes promptly that arm lock 2 lower extreme opens, when required bottle lid is arranged in the below, moves up ejector pin 3 through cylinder 31, and cam surface through on the 3 on the ejector pin is contradicted with the cam surface on the arm lock 2 for the upper end of arm lock 2 shifts up, and the lower extreme of arm lock 2 is inwards clamped promptly. The servo motor 7 is started to drive the transmission wheel 4 on the shell 1 to rotate, namely, the shell 1 rotates and simultaneously drives the clamping arm 2 to rotate, so that the screwing action is realized.
