Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an anti-deformation printing rubber roller. Background Art

[0002] Printing rubber rollers are used in printing machinery for embossing, ink mixing and ink transfer. In order to reduce the cost of use, some printing rubber rollers use a split structure between the rubber roller sleeve and the roller shaft to facilitate the replacement of the rubber roller sleeve on the roller shaft. However, if the rubber roller sleeve is offset during the printing process, the rubber roller sleeve is very likely to be permanently deformed. Moreover, when the printing rubber roller is removed from the printing machinery and placed on a horizontal table, the rubber roller sleeve will come into contact and be squeezed with the table, which will also cause the rubber roller sleeve to deform. Therefore, there is an urgent need for a deformation-resistant printing rubber roller. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, this specific embodiment adopts the following technical solution: it comprises a roller shaft 1 and a rubber roller cover 2, and the roller shaft 1 is covered with a rubber roller cover 2;

[0025] It also contains:

[0026] Baffle plates 3, there are two baffle plates 3, both of which are sleeved on the roller shaft 1, and are movably abutted against each other at the two ends of the rubber roller sleeve 2. A plurality of clip strips 4 are distributed with equal fillets on the inner ring wall of the rubber roller sleeve 2, and the clip strips 4 are clipped in the dovetail grooves provided on the side wall of the roller shaft 1;

[0027] There are two mounting tubes 5, which are fixedly arranged on the side walls of the two baffles 3 respectively, and the mounting tubes 5 are movably sleeved on the roller shaft 1. The mounting tubes 5 are movably penetrated with mounting bolts 6, and the mounting bolts 6 are screwed on the roller shaft 1 through threads. A plurality of guide ribs 17 are distributed at equal fillets on the outer ring wall of the roller shaft 1, and the guide ribs 17 are movably penetrated on the baffles 3 and the mounting tubes 5. The guide ribs 17 can provide guidance and limit in the process of installing the baffles 3 and the mounting tubes 5 on the roller shaft 1;

[0028] A driving disk 7, wherein the driving disk 7 is movably arranged in the baffle plate 3, and movable blocks 9 are movably arranged in several arc-shaped grooves 8 with equal fillets on the driving disk 7, and a support rod 18 is fixedly arranged on the movable block 9, and the support rod 18 is movably inserted in a storage groove 10 provided on the baffle plate 3, and an anti-skid pad 16 is fixedly arranged on the end of the support rod 18. When the support rod 18 is in the process of supporting the roller shaft 1, the anti-skid pad 16 can contact with the ground or the desktop and generate a large friction force to prevent its placement position from being offset, and a limiting mechanism 11 connected to the driving disk 7 is provided on the baffle plate 3;

[0029] The limiting mechanism 11 comprises:

[0030] A control ring 11-1, wherein the control ring 11-1 is movably disposed on a side wall of the baffle plate 3, and a control rod 11-2 is movably inserted in a plurality of limit grooves 13 with equal fillet distribution on the control ring 11-1, and one end of the control rod 11-2 passes through an arc-shaped through groove 12 disposed on the side wall of the baffle plate 3 and is connected to the drive plate 7, and an anti-slip ring 15 is fixedly disposed on the outer ring wall of the control ring 11-1, so that when the staff moves the control ring 11-1 by hand, their hands can contact with the anti-slip ring 15, thereby reducing the phenomenon of the hands slipping off the control ring 11-1;

[0031] A limiting plate 11-3, wherein the limiting plates 11-3 are multiple and are respectively movably disposed in multiple limiting grooves 13, and the limiting plate 11-3 is fixedly connected to the other end of the control rod 11-2, and a spring 11-4 is fixedly disposed on the side wall of the limiting plate 11-3, and one end of the spring 11-4 is connected to the inner wall of the limiting groove 13;

[0032] The limit blocks 11 - 5 are in multiple numbers and are distributed on the side wall of the control ring 11 - 1 with equal rounded corners. The limit blocks 11 - 5 are movably disposed in contact with the positioning grooves 14 provided on the side wall of the baffle 3 .

[0033] When using the utility model, the rubber roller sleeve 2 is sleeved on the roller shaft 1, and the clamping strip 4 is clamped in the dovetail groove, and then the baffle plate 3 and the mounting tube 5 are sleeved on the roller shaft 1, and the baffle plate 3 is abutted against the end of the rubber roller sleeve 2, and then the mounting bolt 6 is used to fix the mounting tube 5 on the roller shaft 1. The positioning provided by the clamping strip 4 and the baffle plate 3 to the rubber roller sleeve 2 can prevent the rubber roller sleeve 2 from being offset in position and causing deformation during the printing process. When the printing rubber roller is removed from the printing machine and needs to be placed, the control ring 11-1 can be moved away from the baffle plate 3. At this time, the spring 11-4 is compressed and the limiting block 11-5 will be disengaged from the positioning groove 14, and then the control ring 11-1 can be rotated. The control ring 11-1 drives the driving disk 7 to rotate through the control rod 11-2, and through the guidance of the arc groove 8, the movable block 9 can drive the support rod 18 to move, so that one end of the support rod 18 is exposed from the storage groove 10. After the movable block 9 moves to the limit position of the arc groove 8, the control ring 11-1 can be released. At this time, the spring 11-4 resets and stretches to move the control ring 11-1 toward the baffle plate 3, so that the control ring 11-1 drives the limit block 11-5 to contact the corresponding positioning groove 14, thereby limiting the control ring 11-1. Later, during the horizontal placement process, the effective support of the support rod 18 can prevent the rubber roller cover 2 from contacting with the desktop and causing deformation.

[0034] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0035] 1. Through the cooperation of the clamping strip 4, the mounting cylinder 5, the mounting bolt 6, the driving plate 7, the movable block 9 and the limiting mechanism 11, it is not only convenient to replace and limit the rubber roller cover 2, but also to avoid deformation caused by deviation during the printing process. In addition, when the rubber roller cover 2 is disassembled, it can be placed horizontally without the need for an additional placement rack, and will not be squeezed and deformed;

[0036] 2. The guide ribs 17 can provide guidance and position limiting when the baffle plate 3 and the mounting tube 5 are installed on the roller shaft 1.

[0037] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
