Description

Technical Field

[0001] The utility model relates to the technical field of cartoning machine equipment, in particular to a track mechanism for a bottle pushing device of a cartoning machine. Background Art

[0002] The bottle pushing device of the cartoning machine is an important equipment in the modern automated packaging production line, which is used to accurately push the bottle into the packaging box. For example, the "A bottle pushing device for a cartoning machine" disclosed in the application number 202021304128.4 applied by the present applicant has two chain guide wheels installed at both ends of its bottle pushing linear guide, and a roller for limiting is provided between the two chain guide wheels. The chain guide wheels are arranged in the chain guide groove. Since each end of its bottle pushing linear guide is guided and rolled by two chain guide wheels, the width of the turning section of its chain guide groove needs to be made larger than that of the straight section. When the chain guide wheel moves to the turning section of the chain guide groove, due to the wider width of the turning section, there are more dummy positions, and the chain guide wheel is prone to left and right deviation, which causes a large impact and causes the chain to stretch. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a track mechanism for a bottle pushing device of a cartoning machine that can reduce the virtual position between the cam follower and the guide slide groove of the curve, so that the cam follower does not swing left and right, reduces the impact, and prevents the chain from being stretched.

[0004] The utility model is realized through the following technical solutions: a track mechanism for a bottle pushing device of a cartoning machine, comprising a straight track, a curved track, a cam bearing, and a cam follower, wherein the straight track and the curved track are connected to form a fully closed track, two cam bearings are provided, and the cam follower is located between the two cam bearings, the straight track is provided with a guide groove and a limit groove distributed along its length direction, the curved track is provided with a guide slide groove distributed along its extension direction, the guide groove and the guide slide groove are adapted to the cam follower, the cam follower can roll along the guide groove and the guide slide groove, the cam follower is used for guiding rolling, the cam bearing is adapted to the limit groove, and the cam bearing is used for limiting.

[0005] Furthermore: the cam follower and the two cam bearings are distributed in a straight line at intervals in the horizontal direction.

[0006] Furthermore: the diameter of the cam bearing is smaller than the diameter of the cam follower, and the height of the cam bearing is greater than the height of the cam follower.

[0007] Furthermore: the guide groove and the limiting groove constitute a stepped groove.

[0008] Furthermore: the width of the limiting groove is D, 16.0mm≦D≦16.5mm, and the width of the guide groove is W, 22.0mm≦W≦22.5mm.

[0009] Furthermore, the cam follower and the cam bearing are arranged at the end of the bottle pushing linear guide rail of the bottle pushing device.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By providing two cam bearings, the cam follower is arranged between the two cam bearings, a guide groove and a limit groove are provided on the straight road, and a guide slide groove is provided on the curve. The cam follower is used for guiding and rolling, and the cam bearing is used for limiting. When moving on the straight road, the two cam bearings are used for limiting. Since only one cam follower is used for guiding and rolling, and the cam follower is located between the two cam bearings, when turning into a curve, the cam follower can roll from the guide groove of the straight road to the guide slide groove of the curve without making the guide groove on the curve wider than the guide groove on the straight road, thereby reducing the virtual position between the cam follower and the guide slide groove, so that the cam follower does not swing left and right when rolling on the curve, reducing impact and preventing the chain from being stretched.

[0018] Figures 1 to 5This is a schematic structural diagram of an embodiment of a track mechanism for a bottle pushing device of a cartoning machine provided by the utility model, comprising a straight track 1, a curved track 2, a cam bearing 3, and a cam follower 4. The straight track 1 and the curved track 2 are connected to form a fully closed track. Two cam bearings 3 are provided, and the cam follower 4 is located between the two cam bearings 3. The straight track 1 is provided with a guide groove 5 and a limit groove 6 distributed along its length direction. The curved track 2 is provided with a guide slide groove 7 distributed along its extension direction. The guide groove 5 and the guide slide groove 7 are adapted to the cam follower 4. The cam follower 4 can roll along the guide groove 5 and the guide slide groove 7. The cam follower 4 is used for guiding rolling. The cam bearing 3 is adapted to the limit groove 6, and the cam bearing 3 is used for limiting.

[0019] The cam follower 4 and the two cam bearings 3 are linearly spaced apart in the horizontal direction.

[0020] The diameter of the cam bearing 3 is smaller than the diameter of the cam follower 4 , and the height of the cam bearing 3 is greater than the height of the cam follower 4 .

[0021] The guide groove 5 and the limiting groove 6 form a stepped groove.

[0022] The width of the limiting groove 6 is D, 16.0 mm≦D≦16.5 mm, and the width of the guide groove 5 is W, 22.0 mm≦W≦22.5 mm.

[0023] In this embodiment, the width D of the limiting groove 6 is 16.2 mm, and the width W of the guide groove 5 is 22.2 mm.

[0024] The cam follower 4 and the cam bearing 3 are arranged at the end of the bottle pushing linear guide 8 of the bottle pushing device.

[0025] Working principle: when the bottle pushing linear guide 8 moves along the fully closed track, it rolls along the guide groove 5 and the guide slide groove 7 through the cam follower 4. When moving on the straight 1, it is limited by the two cam bearings 3. Since only one cam follower 4 is used for guiding and rolling, and the cam follower 4 is located between the two cam bearings 3, when turning into the curve 2, there is no need to make the guide slide groove 7 on the curve 2 wider than the guide groove 5 on the straight 1. The cam follower 4 can also roll from the guide groove 5 of the straight 1 to the guide slide groove 7 of the curve 2, thereby reducing the virtual space between the cam follower 4 and the guide slide groove 7. As a result, when the cam follower 4 rolls on the curve 2, it will not swing left and right, reducing impact and preventing the chain from being stretched.

[0026] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not depart from the present invention should be included in the patent scope of this case.
