DETAILED DESCRIPTION

[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1-4 As shown, a capping device applied to a filling machine comprises a bottle placing seat 1, a capping module 2 and a bottle fixing module 3, wherein the capping module 2 is arranged above the bottle fixing module 3;

[0021] The bottle fixing module 3 includes a fixed claw 31 and a lifting cylinder 32, and the bottle placement seat 1 is a through structure, and the bottle placement seat 1 is located between the fixed claw 31 and the lifting cylinder 32;

[0022] The capping module 2 includes a pressing rod 21 and a capping cylinder 22 . The output shaft of the capping cylinder 22 faces the fixed claw 31 , and the pressing rod 21 is fixedly connected to the output shaft of the capping cylinder 22 .

[0023] In the capping device used in the filling machine, the lifting cylinder 32 can be used to lift the bottle upward from the bottle placement seat 1, so that the bottle cap of the bottle is close to the end of the pressing rod 21, and the cap is located at the end of the pressing rod 21. Then, the upper half of the bottle can be clamped by the fixed claw 31. When the capping cylinder 22 drives the pressing rod 21 to press downward and press the cap to the bottle mouth, the bottle can remain stable and will not tip over.

[0024] It is worth noting that if Figure 1 and 2 As shown, it also includes a cover feeding module 4, which includes a feeding track 41, a feeding claw 42 and a translation cylinder 43. The input end of the feeding track 41 is connected to the cover material bin, and the feeding claw 42 is located between the output end of the feeding track 41 and the cover pressing module 2. The output shaft of the translation cylinder 43 is fixedly connected to the feeding claw 42 to drive the feeding claw 42 to do a linear reciprocating motion between the output end of the feeding track 41 and the pressure rod 21 of the cover pressing module 2.

[0025] The lid silo is used to store the lids and allow the lids to enter the feed track 41 in an orderly manner; a sensor is used to detect whether there are lids entering the output end of the feed track 41. If so, the translation cylinder 43 is used to drive the feed claw 42 to translate to the output end of the feed track 41, and the feed claw 42 is opened to allow the lid to enter the clamping gap of the feed claw 42. The feed claw 42 is closed, and then the translation cylinder 43 is used to drive the feed claw 42 to translate to the end of the pressure rod 21. The capping cylinder 22 drives the pressure rod 21 to move downward to press the lid in the feed claw 42 to the bottle mouth.

[0026] Preferably, Figure 1 , 2 As shown in FIG. 4 , the cap feeding module 4 further includes a base plate 44, the translation cylinder 43 is arranged on the base plate 44, the base plate 44 is provided with a capping hole 441, the pressing rod 21, the capping hole 441, the clamping gap of the fixed pull claw 31, the through hole of the bottle placement seat 1 and the output shaft of the lifting cylinder 32 are arranged in sequence from bottom to bottom and are located on the same vertical line. In this way, driven by the translation cylinder 43, the feeding pull claw 42 can move the cap from the output end of the feeding track 41 to the capping hole 441, and then the pressing rod 21 can press the cap downward, and the cap can be pressed to the bottle mouth after passing through the capping hole 441.

[0027] Optionally, the base plate 44 is further provided with a translation guide rail 442, the translation guide rail 442 is parallel to the extension direction of the output shaft of the translation cylinder 43, the translation guide rail 442 is provided with a slider 45, and the feed claw 42 is arranged on the slider 45. Through the cooperation of the translation guide rail 442 and the slider 45, a guiding function is played, so that the feed claw 42 will not deviate when moving.

[0028] Specifically, Figure 1 and 3 As shown, the capping module 2 further includes a positioning channel 23, which is located between the capping hole 441 and the fixed claw 31, and the clamping gaps of the capping hole 441, the positioning channel 23 and the fixed claw 31 are located on the same vertical line; a plurality of elastic protrusions 231 are evenly distributed on the inner wall of the positioning channel 23. The positioning channel 23 and the elastic protrusions 231 form an elastic positioning mechanism to improve the accuracy of bottle cap pressing. Due to the provision of the elastic protrusions 231, it can adapt to different caps with diameters within a certain range. In addition, the positioning channel 23 also plays a guiding role.

[0029] It is worth noting that if Figure 1 and 3As shown, the capping module 2 also includes an exhaust mechanism 24, which includes a telescopic cylinder 241 and a connecting rod 242. The output shaft of the telescopic cylinder 241 is connected to the connecting rod 242, and the connecting rod 242 extends into the positioning channel 23 after passing through the base plate 44. When the pressing rod 21 drives the cap to press down to the bottle mouth, the output shaft of the telescopic cylinder 241 is in an extended state, so that the connecting rod 242 extends into the positioning channel 23. At this time, one side of the cap will be tilted due to the support of the connecting rod 242, so as to achieve the purpose of exhausting the bottle. After a set time, the output shaft of the telescopic cylinder 241 shrinks and drives the connecting rod 242 to leave the positioning channel 23, and the cap can be completely pressed against the bottle mouth.

[0030] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
