Description

Technical Field

[0001] The utility model belongs to an important structure of a roll paper packaging machine, in particular to a kraft paper edge collecting mechanism of the roll paper packaging machine. Background Art

[0002] For rolls of paper with higher requirements for printing, decoration or other purposes, the weight of the entire roll of paper is relatively large. In order to prevent the surface of the roll of paper from being worn, it is necessary to wrap several layers of kraft paper around the periphery of the roll of paper. Many existing ones adopt a semi-automatic method. The roll of paper is placed on the machine for rotation, and the kraft paper is manually pulled to wrap it, and then cut. After the cutting is completed, the kraft paper is attached to the roll of paper with adhesive tape. The whole process requires manual follow-up, with many processes, consuming more manpower, and the packaging speed is slow. There are also some other semi-automatic structures, such as the application number 201821613886.7, which discloses a kraft paper packaging device for a semi-automatic finished roll of paper packaging line. When packaging this type of roll of paper packaging machine, since the edge of the kraft paper generally exceeds the roll of paper, the operator needs to curl the edge, or wrap the edge of the roll of paper with a corner guard to close the part of the kraft paper that exceeds the edge, so it consumes more manpower and has low efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a kraft paper edge trimming mechanism for a roll paper packaging machine which can solve at least one of the above problems.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 The utility model is a schematic structural diagram of a kraft paper edge collecting mechanism of a roll paper packaging machine.

[0012] Figure 2 The utility model is a schematic structural diagram of an edge collecting device in a kraft paper edge collecting mechanism of a roll paper packaging machine. DETAILED DESCRIPTION

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] Reference Figure 1-2 The kraft paper edge trimming mechanism of the roll paper packaging machine includes a first mounting frame 1, a second mounting frame 2 and an edge trimming device 4. The first mounting frame 1 is arranged corresponding to the second mounting frame 2. The first mounting frame 1 and the second mounting frame 2 are both provided with an edge trimming device 4. The edge trimming device 4 includes an edge trimming wheel 41. When in use, the first mounting frame 1 and the second mounting frame 2 are arranged opposite to each other and are respectively located outside the two end surfaces of the roll paper, so that the edge trimming device 4 can trim the kraft paper beyond the two end edges of the roll paper.

[0015] When the kraft paper edge-closing mechanism of the paper roll packaging machine is in use, the paper roll is located above the first mounting frame 1 and the second mounting frame 2, and the external structure drives the paper roll to rotate, so that the kraft paper is wound on the paper roll to package the paper roll; the edge-closing wheel 41 of the edge-closing device 4 acts on the kraft paper that exceeds the paper roll, and the kraft paper that exceeds the paper roll is closed, so that the edge of the kraft paper can be tightly attached to the outer end face of the paper roll, thereby realizing automatic edge-closing of the kraft paper and improving the packaging efficiency of the paper roll.

[0016] The installation method of the edge trimming device 4 on the first mounting frame 1 is the same as the installation method of the edge trimming device 4 on the second mounting frame 2. The edge trimming device 4 also includes an edge trimming motor 42, which is arranged on the first mounting frame 1, and the edge trimming wheel 41 is connected to the output shaft of the edge trimming motor 42. The edge trimming motor 42 drives the edge trimming wheel 41 to rotate, and through the rotation of the edge trimming wheel 41, the edge trimming wheel 41 acts on the kraft paper from one side, pressing the kraft paper that exceeds the edge of the paper roll to the side of the paper roll, and close to the edge of the paper roll, so as to achieve edge trimming, without manually pressing down the excess part of the kraft paper to trim the edge.

[0017] The edge trimming device 4 also includes a lifting frame 43, a stepper motor 44 and a screw rod 45. The first mounting frame 1 and the second mounting frame 2 are both provided with a vertical slide rail 3. The lifting frame 43 cooperates with the vertical slide rail 3. The edge trimming motor 42 and the stepper motor 44 are both installed on the lifting frame 43. One end of the screw rod 45 is connected to the stepper motor 44, and the other end is sleeved on the top of the first mounting frame 1.

[0018] In actual use, the height position of the edge trimming wheel 41 can be adjusted according to the outer diameter of the paper roll. Specifically, when the edge trimming wheel 41 needs to rise or fall, the stepper motor 44 is started, and the stepper motor 44 drives the screw rod 45 to rotate, so that the stepper motor 44 drives the lifting frame 43 to rise or fall along the screw rod 45; by controlling the rotation direction of the stepper motor 44, the lifting frame 43 can be controlled to rise and fall. In this way, the edge trimming device 4 can trim paper rolls of different sizes, thereby improving applicability. That is, the stepper motor 44 can drive the lifting frame 43 to rise and fall along the vertical slide rail 3, thereby driving the edge trimming motor 42 and the edge trimming wheel 41 to rise to the corresponding height position, so that the edge trimming wheel 41 can act on the kraft paper.

[0019] The vertical slide rail 3 is located outside the first mounting frame 1 and the second mounting frame 2 , and a sliding block 5 is provided at the matching position between the lifting frame 43 and the vertical slide rail 3 , and the sliding block 5 matches with the vertical slide rail 3 .

[0020] The edge trimming wheel 41 includes a mounting shaft 411 and blades 412. One end of the mounting shaft 411 is connected to the output shaft of the edge trimming motor 42. The blades 412 are multiple and evenly distributed at the other end of the mounting shaft 411. The blades 412 are tilted. Since the blades 412 are tilted, when the blades 412 act on the kraft paper, as the blades 412 rotate, the kraft paper can be pressed against both sides of the paper roll to achieve edge trimming. When the edge trimming motor 42 is working, the edge trimming wheel 41 rotates. As the paper roll rotates, the edge trimming wheel 41 can press the kraft paper that exceeds the two ends of the entire paper roll against the sides of the paper roll to achieve edge trimming without manual operation, thus saving labor.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
