Embodiment 1

[0033] combine figure 1 , figure 2 , image 3 , a claw mechanism for capping a paint bucket in this embodiment includes a transmission arm 21 and a claw 22. The claw 22 is composed of an upper claw arm 221, a lower claw arm 222 and a sealing pressure head 224 connected in sequence. A chute 226 is provided on the upper claw arm 221, and the pin shaft connected on the transmission arm 21 can slide in the chute 226 to drive the pressure claw 22 to rotate around the hinge shaft on the lower claw arm 222, so as to realize the sealing of the pressure head 224 against the barrel. The sealing pressure of the cover.

[0034] In this embodiment, the upper claw arm 221 and the lower claw arm 222 are located on the same straight line segment, and the opening direction of the chute 226 is parallel to the setting direction of the claw arm. A bayonet slot 227 is provided at the bottom of the slide slot 226 , and the bayonet slot 227 is an arc slot located on a side away from the transmis...

Embodiment 2

[0037]A claw mechanism used for paint bucket capping in this embodiment has the same basic structure as that in Embodiment 2, furthermore: in this embodiment, the size of the pin shaft matches the size of the chute 226, and the gap between the two Can be controlled within 1.5mm. More optimally, it can be controlled within 1 mm, for example, 0.5 mm. Due to the small clearance, on the one hand, it will not affect the sliding of the pin shaft, and on the other hand, it will not cause the pin shaft to shake greatly. If the gap is too large, when the upper end of the transmission arm 21 travels a certain distance, the angle of rotation cannot be fully reflected on the pressing claw 22, which will result in insufficient accuracy and affect the press-fit sealing effect.

[0038] In addition, it is worth noting that when the pin shaft slides in the chute 226, the chute 226 and the transmission arm 21 are always in a non-parallel state. When the pin shaft is at the top of the chute, th...

Embodiment 3

[0040] A kind of claw mechanism used for capping paint barrels in this embodiment has the same basic structure as that in Embodiment 1, furthermore: the lower claw arm 222 protrudes from the side wall and is provided with an auricle plate 223, and the auricle plate 223 is a protruding arc structure, and a hole is opened on the auricle plate 223 for installing a hinge shaft.

[0041] Through the setting of the chute, although the distance between the two relative sealing heads 224 can be reduced, the distance that can be shortened is limited. In order to install the hinge shaft, the lower end of the pinna plate 223 is connected to the sealing head 224, and the pressure groove 2242 opened on the sealing head 224 is used to seal the cover plate. This structure can further shorten the distance between the sealing head 224 and the hinge shaft , the moment arm is reduced, and then the distance between the hinge shafts on the two opposite pressing jaws 22 can be shortened again, so a...

Abstract

The invention discloses a pressing claw mechanism and a sealing device for sealing a cover of a coating barrel, and belongs to the field of cover sealing devices. The pressing claw mechanism comprisesa transmission arm and a pressing claw, the pressing claw is formed through sequential connection of an upper claw arm, a lower claw arm and a sealing pressing head, a slide groove is formed in the upper claw arm, a hinge pin connected to the transmission arm can slide in the slide groove so as to drive the pressing claw to rotate around a hinge shaft on the lower claw arm, and thus sealing and pressing of a barrel cover by the sealing pressing head is achieved. A bayonet groove is formed in the bottom end of the slide groove, and the bayonet grooves is a circular-arc-shaped groove and located in one side away from the transmission arm. The size of the hinge pin is matched with the size of the slide groove, and when the hinge pin slides in the slide groove, the slide groove is always notparallel to the transmission arm. The pressing claw mechanism and the sealing device change hinge between the transmission arm and the pressing claw to be a connection relationship that sliding and rotating can be achieved at the same time, the radial size of a round shape where the sealing pressing head is located can be shortened, accordingly pressure can be applied conveniently, and improvementof the airtightness of the coating barrel is facilitated.

Description

technical field [0001] The invention relates to the technical field of capping devices, more specifically, to a claw mechanism and a sealing device for capping paint buckets. Background technique [0002] The current paint packaging is divided into two forms: barreled and bagged. After filling, the barreled paint should be sealed with a barrel lid to facilitate transportation and storage. Most of the existing packaging equipment uses the cylinder to drive the upper pressure plate to move, and relies on the transmission rod to transmit power to the pressure jaw on the lower support plate. The outer edges are pressed together to achieve the purpose of packaging. [0003] But existing this capping device, because it will press head down on the outer edge of bung, the size of the circumference of head part must be greater than the size of the outer edge of paint bucket, and the difference is larger, otherwise the head part cannot be lowered. Move to the lid. Due to the large ...
