Description

Technical Field

[0001] The utility model relates to the technical field of paper towel printing machines, in particular to a paper towel printing machine with a positioning function. Background Art

[0002] After embossing, the paper towel will form an uneven surface, which can create many small spaces and can absorb excess moisture more easily. At the same time, the embossing on both sides of the paper towel can make a raised height in the middle of the paper towel, making the paper towel feel softer.

[0003] Among them, a printing machine is needed to emboss the base paper in the paper towel production process. The embossing roller squeezes the surface of the paper vigorously, and the pattern on the embossing roller is pressed on the paper. Usually, the base paper to be processed needs to be installed on the rear frame. There is a certain distance between the rear frame and the printing machine assembly. When the base paper on the rear frame enters the printing machine assembly, there is a certain distance between the rear frame and the printing machine assembly. When the distance is too far, the double-layer base paper is easy to collapse downward under the action of its own weight and become loose, causing the printing position of the printing machine assembly to shift. For this reason, we propose a paper towel printing machine with a positioning function. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] In the process of tissue production, a printing machine is needed to emboss the base paper. The embossing roller squeezes the surface of the paper vigorously, and the pattern on the embossing roller is pressed on the paper. Usually, the base paper to be processed needs to be installed on the rear frame. There is a certain distance between the rear frame and the printing machine assembly. When the base paper on the rear frame enters the printing machine assembly, there is a certain distance between the rear frame and the printing machine assembly. When the distance is too far, the double-layer base paper is easy to collapse downward under the action of its own weight and become loose, causing the printing position of the printing machine assembly to shift. For this reason, we propose a tissue printing machine with a positioning function.

[0026] See also Figure 1-Figure 5 The utility model provides a technical solution for a tissue printing machine with a positioning function: a tissue printing machine with a positioning function, comprising a printing machine body 3, a positioning component 1, the positioning component 1 is used to determine the feeding position of the base paper, the positioning component 1 is arranged on the printing machine body 3, and an adjustment component 2, the adjustment component 2 is used to change the use position of the positioning component 1, and the adjustment component 2 is fixedly connected to the printing machine body 3.

[0027] The tissue printing machine with positioning function of the present embodiment can determine the feeding position of the base paper through the positioning component 1, and can change the use position of the positioning component 1 through the adjustment component 2. In the positioning component 1, the base paper entering the printing machine body 3 is limited in the up and down directions by the bearing roller 8 and the stop roller 9 to prevent the base paper from being too offset and causing the printing machine body 3 to print the base paper inaccurately. When the distance between the base paper rear frame and the printing machine body 3 is far, the outer wall of the strip plate 5 is moved to install the shell 6 to adjust the use position of the bearing roller 8 through the support plate 7, and the bearing roller 8 is used to support the middle position of the base paper to prevent the distance between the rear frame and the printing machine body 3 from being too far. The base paper collapses downward under the action of its own weight, and the base paper is prevented from entering the printing machine body 3 from a loose state, causing printing deviation. The gear 4 is driven to rotate by the lateral movement of the rack 19, and the gear 4 changes the use position of the bearing roller 8 through the strip plate 5, so that the use height of the bearing roller 8 is more suitable for the rear frame where the base paper is placed.

[0028] In some embodiments, the positioning assembly 1 includes a gear 4, which is rotatably connected to the printing machine body 3, a strip plate 5 is fixedly connected to the gear 4, a mounting shell 6 is sleeved on the strip plate 5, a support plate 7 is fixedly connected to the mounting shell 6, a bearing roller 8 is rotatably connected to the support plate 7, and a stop roller 9 is arranged on the bearing roller 8. Before the base paper on the rear frame enters the printing machine body 3, the use position of the gear 4 and the strip plate 5 is adjusted on the side wall of the printing machine body 3, and the strip plate 5 drives the bearing roller 8 to move through the mounting shell 6 and the support plate 7. After the use position of the bearing roller 8 is determined, the base paper is moved from between the bearing roller 8 and the stop roller 9. It passes through and then enters the printing machine body 3 for processing. In this embodiment, the base paper entering the printing machine body 3 is limited in the up and down directions by the support roller 8 and the stop roller 9 to prevent the base paper from being offset too much and causing inaccurate printing position of the base paper by the printing machine body 3. When the distance between the base paper rear frame and the printing machine body 3 is far, the mounting shell 6 is moved on the outer wall of the strip plate 5. The mounting shell 6 adjusts the use position of the support roller 8 through the support plate 7. The support roller 8 is used to support the base paper to prevent the distance between the rear frame and the printing machine body 3 from being too far, and the base paper is offset when it enters the printing machine body 3 from a loose state.

The design of the compression spring 15 can apply downward pressure to the connecting rod 12, increase the clamping force between the stop roller 9 and the supporting roller 8, and ensure that the base paper is in a taut state during the base paper feeding process.

[0032] In some embodiments, the adjustment component 2 includes a fixed plate 16, the fixed plate 16 is fixedly connected to the printing machine body 3, a transmission rod 17 is rotatably connected to the fixed plate 16, a slide plate 18 is threadedly connected to the transmission rod 17, a rack 19 is fixedly connected to the slide plate 18, and the rack 19 is meshed with the gear 4. According to the above embodiment, the fixed plate 16 is provided with two, and the threaded transmission rod 17 rotates in the fixed plate 16 through a bearing. When the inclination angle of the strip plate 5 needs to be adjusted, the transmission rod 17 is rotated to drive the slide plate 18 to move, and the slide plate 18 drives the rack 19 to move.
