Description

A quick disassembly and assembly device for fixing the baffle of a packaging machine. Technical Field

[0001] This invention belongs to the field of cigarette packaging technology, specifically relating to a quick disassembly and assembly device for fixing the baffle of a pack of cigarettes in a packaging machine. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The packaging machine has one internal and one external cigarette pack baffle to assist in the conveying of cigarette packs. Because it comes into contact with the sides of the two packs of cigarettes, glue and residue can accumulate on the baffle surface, causing defects such as folded edges or scratches on the ends of the packs. Cigarette extrusion malfunctions can also cause the baffle to deform, requiring regular maintenance. Due to space constraints, the internal cigarette pack baffle is difficult to disassemble and cannot be removed. Maintenance requires first disassembling the entire external pack forming wheel assembly before performing baffle maintenance. If baffle replacement is necessary, the baffle fixing shaft must also be removed.

[0004] In practice, the following problems exist: First, maintenance is inconvenient because the entire external carton forming wheel device needs to be disassembled, which is quite heavy and requires two people to complete, increasing the labor intensity of maintenance workers and posing safety hazards. Second, maintenance is time-consuming. It requires disassembling the carton forming wheel device, maintaining the cigarette baffle, or disassembling the baffle fixing shaft to replace the baffle, and then reinstalling it. The steps are cumbersome and time-consuming, affecting the operating efficiency of the equipment. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a quick disassembly and assembly device for the fixing shaft of a cigarette pack baffle in a packaging machine. This device solves the problems of difficult disassembly of the cigarette pack baffle and the inability to remove the cigarette pack baffle and fixing shaft as a whole, ensuring the safety of maintenance, reducing the labor intensity of maintenance workers, and improving maintenance efficiency.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] In a first aspect, the present invention provides a quick disassembly and assembly device for a cigarette pack baffle fixing shaft of a packaging machine, comprising: a hollow shaft, a solid shaft, and a clamp; one end of the solid shaft is provided with a first solid half-shaft with a semi-circular radial cross-section, and one end of the hollow shaft is provided with a second solid half-shaft with a semi-circular radial cross-section; the first and second solid half-shafts cooperate and are fixed by the clamp to achieve coaxial transmission and facilitate disassembly; the other end of the solid shaft is provided with a flange for connecting to the machine base wall plate; the other end of the hollow shaft is provided with an adjusting shaft, one end of which is inserted into the hollow shaft, and the other end is provided with a flange seat for fixing the adjusting shaft to the machine base through the flange seat.

[0008] Furthermore, at least two pins are provided on one side of the plane of the first solid half-shaft, and at least two pin holes are provided on one side of the plane of the second solid half-shaft, wherein the number of pins is the same as the number of pin holes.

[0009] Furthermore, both ends of the plane of the first solid half-shaft are provided with groove platforms. One of the groove platforms is hinged to the connecting block at one end of the semi-circular clamp via a pin shaft. The other groove platform is provided with a rotating block and a locking handle. One end of the rotating block is hinged to the groove platform, and the other end of the rotating block is hinged to the locking handle. The locking handle is used to lock the semi-circular clamp to fix the first solid half-shaft and the second solid half-shaft.

[0010] Furthermore, the end of the locking handle that is hinged to the rotating block is an eccentric circle structure, and the rotation center between the locking handle and the rotating block is the center of the eccentric circle, thereby pressing the clamp tight through the eccentric circle structure.

[0011] Furthermore, the hollow shaft is provided with two sets of limiting holes at one end where it is inserted into the adjusting shaft. Each set of limiting holes has at least two limiting holes, and limiting screws are provided in the limiting holes to fix the adjusting shaft and the hollow shaft axially.

[0012] Furthermore, a flat key or spline structure is provided between the adjusting shaft and the hollow shaft to ensure synchronous rotation between the adjusting shaft and the hollow shaft.

[0013] Furthermore, the flange seat at the end of the adjusting shaft is provided with at least three through holes and is connected to the cigarette baffle by bolts.

[0014] Furthermore, the cigarette pack baffles are arranged on both sides of the cigarette pack forming wheel device of the packaging machine. The cigarette pack baffles are used to clamp the ends of the cigarette packs and assist in the conveying of the cigarette packs.

[0015] Secondly, the present invention also provides a method for using a quick-release and disassembly device for a cigarette pack baffle fixing shaft in a packaging machine, comprising:

[0016] Open the locking handle in the upper space of the packaging machine, unfold the locking handle and clamp, vertically remove the adjusting shaft and hollow shaft connected to the cigarette baffle from the pin, remove the cigarette baffle and shaft from the upper space, and perform maintenance and repair on the work platform;

[0017] After maintenance, insert the first and second solid half-shafts from the top and use pins to engage them. Then, fit the semi-circular clamp onto the second solid half-shaft and finally lock the clamp with the eccentric structure of the locking handle.

[0018] Furthermore, during maintenance, after the adjusting shaft is inserted into the hollow shaft, a limiting screw is used to axially fix the adjusting shaft and the hollow shaft.

[0019] Compared with the prior art, the advantages and positive effects of this invention are:

[0020] The present invention provides a quick-release device for the fixing shaft of the cigarette pack baffle. By pulling the locking handle, the semi-circular clamp is released, and the first and second solid half shafts are disengaged, facilitating the removal of the cigarette pack baffle. This solves the problems of difficult disassembly and the inability to remove the cigarette pack baffle and fixing shaft as a whole. It eliminates the need to disassemble the cigarette pack forming wheel device, and avoids the problem of disassembling and reassembling the cigarette pack forming wheel device after maintenance. This ensures the safety of maintenance workers, greatly reduces the difficulty of maintenance, and improves the efficiency of maintenance.

[0021] The quick-release device for fixing the cigarette pack baffle of the present invention solves the problem of having to disassemble the entire external cigarette pack forming wheel device during cigarette pack baffle maintenance. It enables quick replacement or maintenance of the cigarette pack baffle on the workbench, reducing maintenance time from 35 minutes to 7 minutes, improving disassembly and assembly efficiency, ensuring maintenance safety, and reducing the labor intensity of maintenance workers.
