Description

A quick-change structure compatible with cap openers Technical Field

[0001] This utility model relates to the field of filling machine technology, and in particular to a quick-change structure compatible with cap openers. Background Technology

[0002] Before filling packaging drums, the filling machine needs to open the drums. There are two main types of drum lids: concave straight lids and external rotating lids. Most lid opening devices are designed for one type of lid. Therefore, common packaging drum lid opening devices cannot switch between two different lid structures. In production and filling companies, different lid opening devices are usually designed for different lid structures, leading to resource waste and significantly increased costs.

[0003] If a quick-change structure could be designed for both types of bucket lids to meet different lid opening needs, it would undoubtedly greatly reduce the company's production costs. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a quick-change structure compatible with cap openers, solving the problem that conventional cap openers can only open packaging barrels of a single specification.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] A quick-change structure compatible with a cap opener is provided for use on a gripper-type cap opener. The gripper assembly of the gripper-type cap opener has an anti-torsion limiting groove at its center. The quick-change structure is installed in the anti-torsion limiting groove of the gripper assembly. Correspondingly, the top of the quick-change structure has an anti-torsion limiting protrusion. The quick-change structure also has a receiving groove corresponding to the gripping head of the gripper assembly. The gripping head passes through the receiving groove, and the bottom of the gripping head protrudes from the surface of the quick-change structure. The bottom center of the quick-change structure has a straight cap opening head.

[0007] The lower end of the straight-shaped opening head is higher than the height of the clamping head.

[0008] The center of the straight-opening cap has an annular enlarged section, the diameter of which is greater than the cross-sectional width of the straight-opening cap.

[0009] The annular enlarged section is provided with a recessed guide positioning hole; and a fastening groove is provided in the radial direction of the circumference of the quick-change structure between two adjacent clamping heads; it connects with the positioning protrusion of the IBC clamping component through the guide positioning hole, and connects with the locking block of the IBC clamping component through the fastening groove.

[0010] The anti-torsion limiting protrusion is a strip-shaped protrusion, and the arrangement direction of the anti-torsion limiting protrusion is the same as the arrangement direction of the straight-type opening head.

[0011] On both sides of the straight-opening cap, locking screws are used to lock it to the gripper assembly.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This utility model provides a quick-change structure compatible with lid openers, which can be connected to existing lid openers and used as a lid opener for concave I-shaped bucket lids. It can also be used as a connecting structure to connect the lid opening structure of IBC buckets. It adds new functions to the existing lid openers, thereby saving the overall investment in lid openers. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Embodiments

[0022] As shown in Figures 1-5, this utility model provides a quick-change structure compatible with a cap opener, used on a gripper-type cap opener 10. The gripper assembly of the gripper-type cap opener 10 has an anti-torsion limiting groove 11 at its center. The quick-change structure 20 is installed in the anti-torsion limiting groove 11 of the gripper assembly. Correspondingly, the top of the quick-change structure 20 has an anti-torsion limiting protrusion 21. The quick-change structure 20 also has a receiving groove 22 corresponding to the gripping head 12 of the gripper assembly. The gripping head 12 passes through the receiving groove 22, and the bottom of the gripping head 12 protrudes from the surface of the quick-change structure 20. The bottom center of the quick-change structure 20 has a straight cap opening head 23.

[0023] The lower end of the straight-type opening head 23 is higher than the height of the clamping head 12. This facilitates the clamping head 12 to be clamped and connected to the IBC clamping component 30.

[0024] The center of the straight-type opening head 23 has an annular enlarged portion 24, the diameter of which is larger than the cross-sectional width of the straight-type opening head 23. The annular enlarged portion 24 has better mechanical strength, avoiding or reducing deformation of the straight-type opening head 23 during operation.

[0025] As shown in Figures 4-5, the annular enlarged portion 24 has a recessed guide positioning hole 25; and a fastening groove 26 is provided in the radial direction of the circumference of the quick-change structure 20 between two adjacent clamping heads 12; the guide positioning hole 25 connects with the positioning protrusion 31 of the IBC clamping component 30, and the fastening groove connects with the locking block 32 of the IBC clamping component 30. The positioning protrusion 31 and the guide positioning hole 25 form a center positioning fit; the locking block 32 can be driven radially, thereby inserting into the fastening groove 26 in the radial direction; the fastening groove 26 is designed in a cross shape, and correspondingly, the locking block 32 is also designed in a matching shape that can be inserted into the fastening groove 26. The IBC clamping component 30 is designed with three jaws that can connect with the clamping head 12, thereby enabling the clamping head 12 to open the large lid of the IBC packaging barrel through the jaws.

[0026] The anti-torsion limiting protrusion 21 is a strip-shaped protrusion, and the arrangement direction of the anti-torsion limiting protrusion 21 is the same as the arrangement direction of the straight opening head 23.

[0027] On both sides of the straight-opening head 23, locking screws are used to lock and connect it to the gripper assembly.

[0028] Compared with the prior art, the advantages of this utility model are as follows:

[0029] This utility model provides a quick-change structure compatible with lid openers, which can be connected to existing lid openers and used as a lid opener for concave I-shaped bucket lids. It can also be used as a connecting structure to connect the lid opening structure of IBC buckets. It adds new functions to the existing lid openers, thereby saving the overall investment in lid openers.
