Description

Technical Field

[0001] The utility model belongs to the technical field of small box label paper folding, and in particular relates to a combined arc plate device for a packaging machine. Background Art

[0002] In the hard box packaging machine, the folded small box cigarette package label paper contacts the curved plate, and the glued small box label paper is folded and pasted during the rotation of the cigarette package by relying on the curvature of the curved plate. Since the small box label paper moves fast during the wrapping process, the folding process is complicated and has many steps. The curved plate device that comes with the original equipment has a large contact area and friction with the long side of the cigarette package and the ears on both sides of the box cover head during the folding process, which causes the glue points to be squeezed and adhered to the No. 5 wheel mold box, the curved plate, the channel and the distribution window, thereby affecting the appearance quality of the side buckle of the cigarette package, and increasing the maintenance frequency for the machine operator, increasing the number of equipment shutdowns, and reducing the effective operation rate of the equipment. Therefore, through the experience summary and practice in actual production, the design improvement was carried out, and the design of this combined curved plate solves the above defects. Utility Model Content

[0003] In view of the above shortcomings, the purpose of the utility model is to provide a combined arc plate device for a packaging machine, which can realize the good and square folding of the side edges of the trademark paper, facilitate maintenance, reduce the maintenance frequency and time, and can make the arc plate avoid the gluing area by changing the length of the spacer sleeve, thereby reducing the contact area between the trademark paper and the arc plate, reducing friction, and ensuring the appearance quality of the small box of cigarette packs.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A combined arc plate device for a packaging machine comprises: an inner guide plate; an outer guide plate; a spacer sleeve, the interior of which is hollow; an arc plate group, one side of which is connected to the inner guide plate through the spacer sleeve, and the other side of which is connected to the outer guide plate through the spacer sleeve; and a fixing screw, which passes through the outer guide plate, the arc plate group and the spacer sleeve and is fixedly connected to the inner guide plate.

[0006] Through the above scheme, the outer guide plate, spacer sleeve and arc plate group are fixed to the inner guide plate by fixing screws to make them become one. There are three fixing screws, which fix the outer guide plate, spacer sleeve and arc plate group together. The three fixing screws are respectively distributed at the front and rear ends and the middle.

[0007] Furthermore, the arc plate group is composed of a plurality of arc plates, which are connected to each other via spacers, and the arc plates are respectively connected to the inner guide plate and the outer guide plate via the spacers.

[0008] Through the above further scheme, the position of the arc plate relative to the glue coating area can be changed by changing the length of the spacer, so that the arc plate can avoid the glue coating area, and the number of arc plates is determined by the length of the spacer, so that the spacing between the inner guide plate and the outer guide plate corresponds to the length of the cigarette pack. The thickness of the arc plate is 2mm, and the arc plate is provided with three screw holes. The positions of the screw holes correspond to the positions of the countersunk screw holes, so that the fixing screws can pass through the screw holes.

[0009] Furthermore, a plurality of countersunk screw holes are provided on the outer guide plate.

[0010] Through the above further solution, the number of countersunk screw holes is the same as the number of fixing screws, so that the screw heads of the fixing screws do not protrude from the outer guide plate surface and do not interfere with the outer clamping plate.

[0011] Furthermore, the surfaces of the arc-shaped plate, the inner guide plate and the outer guide plate are all provided with arc surfaces, and the curvatures of the arc surfaces on the arc-shaped plate, the inner guide plate and the outer guide plate are all the same.

[0012] Through the above further solution, the arc surfaces on the arc plate, the inner guide plate and the outer guide plate are flush, so that the cigarette pack can slide smoothly.

[0013] Furthermore, the inner diameter of the spacer is larger than the outer diameter of the fixing screw.

[0014] Through the above further solution, the inner diameter of the spacer sleeve is slightly larger than the outer diameter of the fixing screw to avoid the spacer sleeve from being eccentrically moved downward during the fixing process due to the excessive inner diameter, and contacting the small box trademark paper to generate resistance.

[0015] Furthermore, both ends of the arc-shaped plate are provided with chamfers.

[0016] Through the above further scheme, the chamfering of the entrance end of the arc plate is to allow the front of the cigarette pack and the dovetail corner of the cigarette pack to enter the arc plate smoothly, and the chamfering of the tail of the arc plate is to allow the cigarette pack ejection component to be formed smoothly.

[0017] Furthermore, the front end of the inner guide plate is chamfered.

[0018] The above further solution facilitates the smooth introduction of the cigarette pack into the arc folding device.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The outer guide plate is provided with countersunk screw holes to facilitate installation and fixation, so that the screw heads of the fixing screws do not protrude from the surface of the outer guide plate, thereby preventing them from interfering with the outer clamping plate.

[0021] 2. By changing the length of the spacer, the position of the arc plate relative to the gluing area can be changed, so that the arc plate can avoid the gluing area, thereby preventing the glue points from being squeezed and sticking to the No. 5 wheel mold box, the arc plate, the channel and the distribution window, thereby reducing the maintenance frequency, improving the appearance quality of the cigarette packs, and increasing the yield rate of the cigarette packs.

The inner guide plate 1, the outer guide plate 2 and the plurality of arc plates 4 are connected to each other through the spacer sleeve 3, and the fixing screw 5 passes through the outer guide plate 2, the plurality of arc plates 4, the spacer sleeve 3 and the inner guide plate 1 to be fixedly connected. The fixing screw 5 fixes the outer guide plate 2, the spacer sleeve 3 and the arc plate group to the inner guide plate 1 to make them a whole, and the arc plates 4 are also connected to each other through the spacer sleeve 3.

[0031] Among them, there are three fixing screws 5, which are respectively distributed at the front end, the rear end and the middle of the outer guide plate 2, which can enhance the connection strength of the inner guide plate 1, the outer guide plate 2, the spacer 3 and the multiple arc plates 4.

[0032] Among them, three countersunk screw holes 21 are opened on the outer guide plate 2, and their positions correspond to the fixing screws 5, so that the fixing screws 5 can pass through the countersunk screw holes 21, and the screw heads of the fixing screws 5 can be located in the countersunk screw holes 21, so that the screw heads do not protrude from the outer guide plate surface and do not interfere with the outer clamping plate.

[0033] Among them, the interior of the spacer 3 is hollow, which allows the fixing screw 5 to pass through the spacer 3. The inner diameter of the spacer 3 is slightly larger than the outer diameter of the fixing screw 5, so as to avoid the spacer 3 being eccentrically downward during the fixing process due to the excessive inner diameter, and contacting the small box trademark paper to generate resistance.

[0034] The arc-shaped plate 4 is provided with three screw holes 41 , and the positions of the screw holes 41 correspond to the positions of the countersunk screw holes 21 , so that the fixing screws 5 can pass through the screw holes 41 .

[0035] Among them, three threaded holes 11 are provided on the inner guide plate 1 , and the positions of the threaded holes 11 correspond to the positions of the countersunk screw holes 21 , and the threaded holes 11 are threadedly connected to the ends of the fixing screws.

[0036] Among them, the position of the arc plate 4 relative to the glue coating area can be changed by changing the length of the spacer 3, so that the arc plate 4 can avoid the glue coating area, and the number of arc plates 4 is determined by the length of the spacer 3, so that the distance between the inner guide plate 1 and the outer guide plate 2 corresponds to the length of the cigarette pack.

[0037] It should be noted that the number of the arc-shaped plates 4 can be arbitrarily added or deleted according to the needs, and the length of the spacer 3 can also be changed to change the position of the arc-shaped plates 4.

[0038] The thickness of the arc plate 4 is 2 mm.

[0039] Among them, the surfaces of the arc plate 4, the inner guide plate 1 and the outer guide plate 2 are all provided with arc surfaces, the arc surfaces of the arc plate 4, the inner guide plate 1 and the outer guide plate 2 are flush, and the curvature of the arc surfaces on the arc plate 4, the inner guide plate 1 and the outer guide plate 2 are the same, so that the cigarette pack can slide smoothly.

[0040] Among them, both ends of the arc plate 4 are chamfered. The chamfer at the entrance end of the arc plate 4 is to allow the front of the cigarette pack and the dovetail corner of the cigarette pack to enter the arc plate 4 smoothly, and the chamfer at the tail of the arc plate 4 is to allow the cigarette pack ejection component to be formed smoothly.

[0041] Among them, the front end of the inner guide plate 1 is chamfered to facilitate the smooth introduction of the cigarette package into the arc folding device.

[0042] The thickness of the outer guide plate 2 is greater than the thickness of the arc plate 4 .

[0043] The specific implementation process of this embodiment is as follows:

[0044] Reference Figure 2 As shown, after the label paper is glued and folded, it gradually enters the arc plate 4 device at the 12 o'clock direction. At this time, the long sides and short oblique sides of the ears of the small box cigarette pack follow the curvature of the arc plate 4 to run to the 9 o'clock direction. Under the action of the fifth wheel push rod and the external rod, the cigarette pack is positioned and pushed out. In this process, the lower long side and the lower short side ears are folded by the fixed track, and the upper long side and the upper short side ears are folded by the tail of the arc plate 4. The utility model can achieve the appearance quality of the small box cigarette pack without offset printing and scratching, and the side folding is flat, which improves the qualified rate of the cigarette pack; to a certain extent, it reduces the maintenance time of the operator, reduces the number of equipment shutdowns, and improves the effective productivity of the equipment. The utility model device has a simple structure, is easy to adjust, and has strong operability.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
