Description

Technical Field

[0001] The invention relates to a bracket, in particular to a fifth wheel inner frame paper limiting device for a packaging machine. Background Art

[0002] During the operation of the YB45 packaging machine, there was a phenomenon of paper jam sinking after the cigarette pack came out of the X2 flipper. After careful observation and research, the packaging machine maintenance worker concluded that the width of the semi-circular paper jam positioning groove of the packaging machine's fifth wheel was larger than the width of the paper jam, causing the paper jam to move up and down in the positioning groove. The paper jam positioning was inaccurate, resulting in the paper jam sinking.

[0003] In order to solve the problem of paper jam sinking, it is necessary to replace the arc guide rail on one side, and change the width of the paper jam positioning groove by replacing the arc guide rail. Since the arc guide rail in the prior art is an integrated structure, it needs to be replaced as a whole, which increases the replacement cost on the one hand and causes waste of materials on the other hand. Moreover, when producing products of different brands, the width of the paper jam positioning groove needs to be adjusted each time the paper jam is replaced, which greatly affects the production efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a paper limiting device in the inner frame of the fifth wheel of a packaging machine to solve the technical problems in the prior art. It can quickly adjust the width of the paper jam positioning groove, solve the problem of paper jam sinking, and effectively ensure production efficiency.

DETAILED DESCRIPTION

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0016] Embodiments of the present invention: Figure 1-Figure 3 As shown, a paper limiting device for the inner frame of the fifth wheel of a packaging machine includes a first arc guide rail assembly 1 and a second arc guide rail assembly 2. The first arc guide rail assembly 1 includes a fixed guide rail 3 and a movable guide rail 4. The movable guide rail 4 is connected to the fixed guide rail 3 by a plurality of adjusting screws 5. The movable guide rail 4 is located between the fixed guide rail 3 and the second arc guide rail assembly 2. The movable guide rail 4 is provided with a first paper jam limiting boss 6, and the second arc guide rail assembly 2 is provided with a second paper jam limiting boss 7.

[0017] When the paper jam of the fifth wheel of the packaging machine sinks or when changing the product brand, the paper jam of different thickness is replaced, there is no need to disassemble the first arc guide assembly 1, only the second arc guide assembly 2 needs to be removed, and then the adjustment screw 5 is rotated with a tool to change the spacing between the movable guide 4 and the fixed guide 3. By changing the position of the movable guide 4, the distance between the first limiting boss 6 and the second limiting boss 7 is changed, thereby changing the limiting width of the paper jam, thereby preventing the paper jam from sinking. The structure of the present invention does not need to produce various first arc guide assemblies 1 of different specifications, which greatly reduces the amount of materials used, reduces waste, reduces adjustment time, and improves production efficiency.

[0018] In a specific embodiment, the first arc guide rail assembly 1 also includes a guide rail fixing seat 8 and a guide positioning pin 9. The fixed guide rail 3 and the guide rail fixing seat 8 are an integrated structure. The fixed guide rail 3 is fixedly installed on the packaging machine through the guide rail fixing seat 8. The second arc guide rail assembly 2 is a prior art, and its installation position on the packaging machine is fixed and cannot be adjusted. A plurality of guide positioning pins 9 are arranged on the surface of the fixed guide rail 3 facing the movable guide rail 4. The number of the guide positioning pins 9 is 7. The movable guide rail 4 is formed with guide positioning holes 10 arranged one by one opposite to the guide positioning pins 9, that is, the number of the guide positioning holes 10 is also 7.

[0019] Three equally spaced mounting grooves 11 are formed on the surface of the movable guide rail 4 facing the second arc-shaped guide rail assembly 2, a mounting seat 12 is provided in each mounting groove 11, the mounting seat 12 is interference fit with the mounting groove 11, a first through hole 13 is formed at the bottom of each mounting groove 11, a second through hole 14 is formed on the mounting seat 12, a threaded hole 15 arranged opposite to the first through hole 13 is formed on the fixed guide rail 3, and the adjusting screw 5 is threadedly connected to the threaded hole 15.

[0020] The setting of the guide positioning pin 9 can limit the circumferential freedom of the movable guide rail 4 on the one hand, and can make the various positions of the movable guide rail 3 bear force evenly on the other hand, so as to ensure that the paper jam is well limited. The setting of the mounting seat 12 and the mounting groove 11 can increase the adjustable range of the movable guide rail 4, so that it can be applied to paper jams of more specifications.

[0021] Furthermore, a top screw installation threaded hole 16 is formed on the movable guide rail 4 and is arranged perpendicularly to the first through hole 13 and is connected to each other. A top screw 17 is installed in the top screw installation threaded hole 16. The function of the top screw 17 is that when the distance between the end of the adjusting screw 5 and the fixed guide rail 3 is changed by rotating the adjusting screw 5, since the first through hole 13 and the second through hole 14 are not threaded, the movable guide rail 4 needs to be fixed together with the adjusting screw 5 by means of the top screw 17, thereby fixing the movable guide rail 4.

[0022] In a preferred embodiment, a spare threaded hole is provided on both sides of each threaded hole 15, and a spare through hole is provided on both sides of each second through hole 14. When the threaded hole 15 fails, the adjusting screw 5 can be installed through the spare threaded hole and the spare through hole without replacing the mounting seat 12.

[0023] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
