Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, and more specifically, to a fixing and locking device for a glue cylinder of a packaging machine. Background Art

[0002] The YB65 CT hard strip packaging machine is a device in the GD hard box packaging unit. Its main function is to wrap the cigarette packs with transparent paper from the upstream machine into strip cigarette boxes in the form of two layers with five packs arranged side by side horizontally. Through the strip box gluing device, glue is applied to the long folding edge and two short edges of the hard box paper.

[0003] At present, the existing CT hard strip packaging machine in the packaging unit does not have an electronic locking device for the glue cylinder in place, but only a mechanical locking handle. Therefore, during the production process, due to the vibration of the equipment operation, it is easy for the mechanical locking handle of the glue cylinder to slide open or the mechanical locking handle of the glue cylinder not to be locked in place, ultimately resulting in the glue cylinder sliding open. Also, because the 3S467 glue cylinder in-place detection is a micro switch, and the detection switch is still in the compressed state after the glue cylinder slides open, the machine will not stop, but the distance between the applicator and the glue wheel increases, which will cause no glue points on the strip-packed cigarettes and the strip packs to come loose, seriously affecting the effective operation rate of the entire production unit equipment and reducing the production efficiency of the enterprise. In the light case, it requires manual box turning, which is laborious and costly; in the heavy case, it leads to defective products flowing into the market, seriously affecting the brand reputation of the enterprise.

[0004] Therefore, how to provide a fixing and locking device for a glue cylinder of a packaging machine has become a technical problem urgently to be solved in this field. Content of the Utility Model

[0026] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present utility model or its application or use.

[0027] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0028] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of exemplary embodiments may have different values.

[0029] As Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a fixing and locking device for the glue cylinder of a packaging machine. The packaging machine includes a glue cylinder 5 and a guide rail 6, and the glue cylinder 5 is slidably arranged on the guide rail 6; the fixing and locking device for the glue cylinder of the packaging machine includes: a rotating handle 1, a connecting component 2 and a locking component 3, and both the rotating handle 1 and the locking component 3 are arranged outside the glue cylinder 5.

[0030] The connecting component 2 includes a fixed flange 21, the fixed flange 21 is fixed on the glue cylinder 5, and the fixed flange 21 has a first connecting hole 22. The rotating handle 1 is fixed on the packaging machine and can rotate along the fixed flange 21, and the rotating handle 1 abuts against the fixed flange 21, which also has a locking effect on the glue cylinder 5.

[0031] The locking component 3 includes a pin shaft 31, a spring 32 and a push handle 33. The spring 32 is sleeved on the pin shaft 31, and the first end of the pin shaft 31 penetrates through the rotating handle 1 and is connected to the push handle 33, and the second end of the pin shaft 31 is inserted into the first connecting hole 22. The spring 32 is always in a compressed state.

[0032] During use, the operator acts on the rotating handle 1 to make the rotating handle 1 rotate and drive the pin shaft 31 to rotate. When the pin shaft 31 corresponds to the first connecting hole 22, the operator presses the push handle 33 to make the push handle 33 move towards the glue cylinder 5, thereby driving the pin shaft 31 to move towards the glue cylinder 5. At the same time, the spring 32 provides a thrust force on the pin shaft 31 in the direction towards the glue cylinder 5, so that the pin shaft 31 moves towards the glue cylinder 5 and is inserted into the first connecting hole 22, thereby fixing the rotating handle 1 and avoiding the problem that the glue cylinder 5 moves due to the movement of the rotating handle 1, resulting in no glue on the glue application roller.

[0033] When it is necessary to release the lock on the rotating handle 1, the operator pulls the push handle 33 in the direction away from the glue cylinder 5. The movement of the push handle 33 drives the pin shaft 31 to move in the direction away from the glue cylinder 5, and the pin shaft 31 is removed from the first connecting hole 22, thereby releasing the locking of the rotating handle 1.

[0034] In the present utility model, the fixed flange 21 is fixed on the glue cylinder 5, and a first connection hole 22 is provided on the fixed flange 21. The spring 32 is sleeved on the pin shaft 31, and the first end of the pin shaft 31 penetrates through the rotating handle 1 and is connected to the push handle 33, and the second end of the pin shaft 31 is inserted into the first connection hole 22. During use, an operator acts on the rotating handle 1 to make the rotating handle 1 rotate, driving the pin shaft 31 to rotate. When the pin shaft 31 corresponds to the first connection hole 22, the operator presses the push handle 33 to make the push handle 33 move towards the glue cylinder 5, thereby driving the pin shaft 31 to move towards the glue cylinder 5 and insert into the first connection hole 22, thus fixing the rotating handle 1, avoiding the problem that the movement of the rotating handle 1 causes the glue cylinder 5 to move and results in no glue on the glue application roller, reducing the labor intensity of the operator, improving the work efficiency, and ensuring the product quality.

[0035] In an embodiment of the glue cylinder fixing and locking device of the packaging machine of the present utility model, as Figures 1 to 4 shown, the rotating handle 1 includes a connecting plate 11 and a boss 12. A second connection hole 15 is provided at the first end of the connecting plate 11, and the second end of the connecting plate 11 is connected to the boss 12. The first end of the pin shaft 31 penetrates through the second connection hole 15 and is connected to the push handle 33.

[0036] Specifically, the diameter of the first connection hole 22 is equal to the diameter of the second connection hole 15. As Figure 4 shown, the pin shaft 31 includes a first connecting rod and a second connecting rod. The diameter of the first connecting rod is equal to the diameter of the first connection hole 22, and the diameter of the second connecting rod is smaller than the diameter of the first connecting rod. The first end of the first connecting rod is connected to the first end of the second connecting rod, the second end of the first connecting rod is inserted into the first connection hole 22, the second end of the second connecting rod is slidably connected to the second connection hole 15, and the spring 32 is sleeved on the second connecting rod.
