Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a connection structure between a film-penetrating shaft and a damping mechanism. Background Art

[0002] The film placing mechanism of the existing packaging machine generally includes a frame, a damping mechanism is arranged on the frame, a film-penetrating shaft is arranged on the damping mechanism, and a film roll is arranged on the film-penetrating shaft. When the film roll is used up and needs to be replaced with a new one, the film-penetrating shaft and the damping mechanism and other components need to be disassembled together, which is labor-intensive and inconvenient to replace.

[0003] In order to solve the above technical problems, in the prior art, a connection structure is provided between the film-penetrating shaft and the damping mechanism, such as a connecting flange, wherein the connecting flange includes two flanges that are detachably connected by screws. When the film roll is used up and needs to be replaced with a new one, although it is no longer necessary to remove the damping mechanism and other components, it is still necessary to remove the screws on the connecting flange to remove the film-penetrating shaft. After replacing the new film roll, the film-penetrating shaft is placed back on the frame, and screws are required to fix the two flanges. This structure also has the problem of inconvenient replacement. Summary of the invention

[0004] In order to solve the above technical problems, the utility model proposes a connection structure between a film-penetrating shaft and a damping mechanism, which can effectively solve the problem of inconvenient operation when replacing a film roll.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] A connection structure between a transmembrane shaft and a damping mechanism, the connection structure comprising a first connector arranged at one end of the transmembrane shaft and a second connector arranged at one end of the damping mechanism; the first connector and the second connector both comprise a connector body and a transfer boss extending outward from the connector body, and one side of the transfer boss forms a splicing notch with the connector body; when the first connector and the second connector are spliced ​​together, the transfer bosses of the first connector and the second connector are opposite, the transfer boss of the first connector is located at the splicing notch on one side of the transfer boss of the second connector, and the transfer boss of the second connector is located at the splicing notch on one side of the transfer boss of the first connector.

[0007] The splicing surface where the transfer boss of the first connector contacts the transfer boss of the second connector is a plane.

[0008] The splicing surface where the transfer boss of the first connector contacts the transfer boss of the second connector is a broken line surface.

[0009] A protrusion and a recess are provided on the side of the transfer boss relative to the splicing notch, the protrusion of the transfer boss of the first connecting head is correspondingly engaged with the recess of the transfer boss of the second connecting head, and the protrusion of the transfer boss of the second connecting head is correspondingly engaged with the recess of the transfer boss of the first connecting head.

[0010] The recessed portion is located between the raised portion and the connector body, the raised portion and the recessed portion share a same wall, and the wall is inclined downward toward the recessed portion.

[0011] The connector body is in the shape of a hollow ring with a notch, wherein the hollow position is used to assemble the shaft end of the membrane-penetrating shaft and / or the damping mechanism, and a bolt hole is arranged at the notch, and the connector body is clamped to the shaft end of the membrane-penetrating shaft and / or the damping mechanism by connecting bolts.

[0012] The splicing surface where the transfer boss of the first connector contacts the transfer boss of the second connector is in an Ω shape.

[0013] The connector body and the transfer boss are integrally formed.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, the connection structure is simple in structure and easy to install and separate. Since the first connector and the second connector are contact-connected, when the film roll needs to be replaced, it is only necessary to remove the film-penetrating shaft and separate the first connector and the second connector. Since the connector body of the second connector extends outward with a transfer boss, the second connector will automatically rotate under the action of its own gravity, so that the transfer boss is always located at the bottom of the second connector, and the splicing surface of the transfer boss faces upward, which is convenient for the installation of the first connector and the film-penetrating shaft. That is, during installation, it is only necessary to align the transfer boss of the first connector with the splicing notch in the second connector, and then place the first connector.

[0016] 2. In the utility model, the joint surface where the transfer boss of the first connecting head contacts the transfer boss of the second connecting head is a plane, so that the first connecting head and the second connecting head are connected in a plane contact manner, the structure is simple, and the separation and installation method of the second connecting head and the first connecting head are simple, which is suitable for working conditions that require axis adjustment.

[0017] 3. The joint surface where the transfer boss of the first connector contacts the transfer boss of the second connector is a broken line surface, which can limit the axial movement of the first connector and the membrane-penetrating shaft, so that the connection structure can be used in situations where the axial position of the membrane-penetrating shaft is fixed.

[0018] 4. By providing a raised portion and a recessed portion on the side of the transfer boss relative to the splicing notch, it is convenient to limit the movement of the first connector and the membrane-penetrating shaft in the axial direction.

[0019] 5. The protrusion and the recess share the same wall, which is inclined downward toward the recess. The structural design of the wall facilitates good guiding effect when installing and separating the first connector, and also has a good effect of limiting the axial movement of the first connector.

[0020] 6. The connector body and the transfer boss are integrally formed, which is convenient for processing, and the structures of the first connector and the second connector are more stable. BRIEF DESCRIPTION OF THE DRAWINGS
