Description

Technical Field

[0001] The utility model belongs to the technical field of rewinding machines, in particular to a rewinding machine for ribbon production. Background Art

[0002] The ribbon is a printing consumable material, mainly used in dot matrix printers. It is made of a nylon base woven with ink and then dyed. After its initial production, it needs to be rewound and slit by a rewinder. In order to ensure the tension of the ribbon rewinding, the traditional ribbon rewinder uses a slip shaft to ensure the tension of the finished paper roll. The slip shaft includes an air shaft and a slip ring mounted on the air shaft. A reel is mounted on the outside of the slip ring. The paper roll with a constant tension is rewound on the reel. However, the reel will deflect along the axis of the slip shaft, making the end face of the finished paper roll uneven.

[0003] The Chinese invention patent with authorization announcement number CN110143468B discloses a rewinding machine, which separates adjacent rolls at a fixed distance by setting a separation ring, thereby preventing the rolls from moving along the axis of the first rewinding shaft, and further making the end faces of the paper rolls rewound on the rolls neat. It also ensures that the rolls are definitely fitted on the slip rings by arranging them side by side, thereby ensuring that the tension of the rewound finished paper rolls is constant and meets the requirements. However, the device still has some other problems. For example, the tightness of the device cannot be adjusted during use. Since the roll diameter of the roll material will continue to change, the tension of the roll material will continue to change with the change in the roll diameter. If the roll tension is not controlled, the roll material will wrinkle or break. Utility Model Content

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a rewinding machine for ribbon production, comprising:

[0031] The mounting frame 100 has a limiting groove 110 formed on its inner wall;

[0032] The sliding plate 120 is disposed inside the limiting groove 110;

[0033] The limiting plate 130 is disposed above the sliding plate 120;

[0035] The tensioning mechanism 200 is disposed between the limiting plate 130 and the supporting plate 140;

[0036] The tensioning mechanism 200 includes:

[0037] The driving mechanism 210 is disposed on a side of the support plate 140 close to the limiting plate 130;

[0038] The adjustment disk 220 is disposed on the output shaft of the driving mechanism 210;

[0039] The tensioning roller 230 is disposed on a side of the adjustment disk 220 close to the limiting plate 130;

[0040] Among them, two tensioning rollers 230 are provided on the adjusting disk 220, and the two tensioning rollers 230 are symmetrically arranged on the adjusting disk 220. A winding roller 240 and a discharge roller 250 are provided on the side of the limiting plate 130 close to the support plate 140, and the discharge roller 250 and the winding roller 240 are arranged on both sides of the tensioning mechanism 200.

[0041] In the present technical solution, in order to generate different tensions when rewinding ribbons of different materials, a limiting slot 110 is provided in the middle of the mounting frame, a slidable sliding plate 120 is provided inside the limiting slot 110, a limiting plate 130 is fixedly provided on the upper surface of the sliding plate 120, mounting holes are provided inside the sliding plate 120 and the limiting slot 110, the sliding plate 120 can be fixed inside the limiting slot 110 by bolts and the mounting holes, thereby fixing the limiting plate 130, a support plate 140 is fixedly provided on the mounting frame 100 on the side opposite to the limiting plate 130, a tensioning mechanism 200 is provided between the support plate 140 and the limiting plate 130, and a driving mechanism 210 of the tensioning mechanism 200 is fixed on the support plate 140 away from the limiting plate On one side of the positioning plate 130, the output shaft of the driving mechanism 210 is fixedly connected to the adjusting disk 220, and two tensioning rollers 230 are fixedly provided on the side of the adjusting disk 220 close to the limiting plate 130, and the two tensioning rollers 230 are symmetrically arranged about the adjusting disk 220, and a winding roller 240 and a feeding roller 250 are fixedly provided on the side of the layer support plate 140 close to the limiting plate 130, and the feeding roller 250 and the winding roller 240 are arranged at diagonal positions of the adjusting disk 220, so that the ribbon can be easily tensioned. The driving mechanism 210 drives the rotation of the adjusting disk 220, thereby driving the distance between the two tensioning rollers 230 and the winding roller 240 and the feeding roller 250, so that the tension on the ribbon between the feeding roller 250 and the winding roller 240 can be achieved.

[0042] Example 2:

[0043] This embodiment provides a rewinding machine for ribbon production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, two penetrating fan-shaped grooves 131 are defined on the limiting plate 130 , and the tensioning roller 230 slides inside the fan-shaped grooves 131 .

[0045] In this technical solution, in order to facilitate the smooth rotation of the two tensioning rollers 230 when the adjustment disk 220 rotates, two penetrating fan-shaped grooves 131 are opened on the limit plate 130. The two fan-shaped grooves 131 are the same size as the diameter of the tensioning roller 230. This makes it convenient for the tensioning roller 230 to rotate and slide inside the fan-shaped grooves 131, thereby facilitating the change of the tensioning force of the ribbon between the two tensioning rollers 230.

[0046] Example 3:

[0047] This embodiment provides a rewinding machine for ribbon production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] like Figure 1 and Figure 2 As shown, in this embodiment, a scale line 231 is provided on the tensioning roller 230 , and the starting point of the scale line 231 is provided at one end of the tensioning roller 230 close to the support plate 140 .

[0049] In the present technical solution, in order to facilitate the tensioning mechanism 200 to adapt to the tensioning of ribbons of different widths, a scale line 231 is provided on the tensioning roller 230, and the starting point of the scale line 231 is set at one end of the tensioning roller 230 close to the support plate 140. In this way, the limit plate 130 can be changed to a suitable position along the direction of the limit groove 110 according to the width of the ribbon, so that the distance between the limit plate 130 and the adjustment disk 220 is the distance of the ribbon to be rewound. In this way, when the ribbon is rewound, both sides of the ribbon can be limited, thereby ensuring that the ribbon will not be displaced when being rewound, resulting in rewinding wrinkles.

[0050] Example 4:

[0051] This embodiment provides a rewinding machine for ribbon production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] like Figure 1 As shown, in this embodiment, the driving mechanism 210 is a servo motor or a stepper motor.

[0053] In this technical solution, in order to be able to change the tension of the tensioning mechanism 200 so that it can become larger or smaller, the motor 260 is a servo motor or a stepper motor, so that it can drive the adjustment disk 220 to rotate forward or reverse, thereby controlling the change in the tension of the ribbon between the tensioning rollers 230 on the adjustment disk 220.

[0054] Example 5:

[0055] This embodiment provides a rewinding machine for ribbon production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] like Figure 1 and Figure 2 As shown, in this embodiment, two through holes 141 are opened on the support plate 140. The through holes 141 are as large as the diameters of the winding roller 240 and the unwinding roller 250. The unwinding roller 250 and the winding roller 240 can pass through the support plate 140 through the through holes 141.

[0057] In this technical solution, in order to facilitate the installation and removal of the ribbon roll, two through holes 141 are opened on the support plate 140. The diameters of the two through holes 141 are the same as the diameters of the winding roller 240 and the unwinding roller 250, and the positions of the two through holes 141 correspond to the positions of the unwinding roller 250 and the winding roller 240. In this way, before rewinding, the limit plate 130 can be set away from the support plate 140. After the ribbon roll is installed into the unwinding roller 250 and the limit plate 130 is changed to the appropriate position, the unwinding roller 250 and the winding roller 240 can pass through the support plate 140 to rewind the ribbon after tensioning. After the ribbon is rewound, the limit plate 130 is set away from the support plate 140, so that the rewound ribbon roll can be conveniently and quickly removed from the winding roller 240.

[0058] Example 6:

[0059] This embodiment provides a rewinding machine for ribbon production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] like Figure 1 and Figure 2 As shown, in this embodiment, the winding roller 240 and the unwinding roller 250 are fixedly connected to the output shaft of the motor 260 at one end close to the limiting plate 130 , and the motor 260 is fixedly arranged on the side of the limiting plate 130 away from the support plate 140 .

[0061] In this technical solution, in order to facilitate the winding of the ribbon, the output shaft of the motor 260 is fixedly connected to one end of the winding roller 240, and the motor 260 is fixedly arranged at the end of the limit plate 130 away from the support plate 140, so that when the motor 260 rotates, it can drive the winding roller 240 to rotate, so that the tensioned ribbon can be wound up. At the same time, a motor 260 is also provided at one end of the unwinding roller 250, so as to ensure that the winding speed of the winding roller 240 is the same as the unwinding speed of the unwinding roller 250. In this way, the tension of the ribbon between the winding roller 240 and the unwinding roller 250 can be adjusted by adjusting the positions of the two adjustment rollers.

[0062] Example 7:

[0063] This embodiment provides a rewinding machine for ribbon production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] like Figure 1 and Figure 2 As shown, in this embodiment, a limit plug 270 is provided on the winding roller 240 and the unwinding roller 250 , and a rubber ring 271 is fixedly provided on the inner wall of the limit plug 270 .

[0065] In the present technical solution, in order to prevent the ribbon from wrinkling when the unwinding roller 250 is unwinding and the winding roller 240 is winding, a detachable limit plug 270 is mounted on the unwinding roller 250 and the winding roller 240, and a rubber ring 271 is provided on the inner wall of the limit plug 270.
