Detailed Description

The printing roll of the present utility model will be described in more detail below in conjunction with the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art may modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1 and 2, an embodiment of the present utility model proposes a printing roller including a mandrel 1, a drum 2, and a positioning member 3.

The roller 2 is detachably sleeved on the mandrel 1. The surface of the roller 2 is carved with patterns, when different patterns are needed to be changed to print different products, the mode of changing the roller 2 can be performed, namely, the whole change of the printing roller is not needed, the change rate is further effectively improved, a plurality of integrated printing rollers are not needed, only a plurality of rollers 2 are needed, and the equipment cost is effectively reduced.

In this embodiment, a specific positioning member 3 is provided to facilitate the connection or disconnection of the roller 2 to or from the mandrel 1.

Specifically, the positioning member 3 includes a positioning disc 31, a shaft sleeve 32, an abutment block 33, and a driving member 34.

The positioning disk 31 is slidably mounted on the outer wall of the mandrel 1, and can be kept relatively fixed with the mandrel 1. When the positioning disc 31 slides, the position of the integral positioning piece 3 can be changed to mount the rollers 2 with different sizes, so that the device can be suitable for printing materials with different sizes, and the application range of the whole device is wider.

The shaft sleeve 32 is arranged on one side of the positioning disc 31 and sleeved outside the mandrel 1. Providing a fulcrum for the installation of the subsequent driver 34.

The abutting block 33 is slidably mounted on the side wall of the positioning disk 31 and can abut against the roller 2; when the abutting block 33 abuts against the roller 2, the roller 2 and the positioning plate 31 are relatively fixed. Namely, the roller 2 and the positioning disc 31 are fixed through the abutting of the abutting block 33 and the roller 2, and the positioning disc 31 can be relatively fixed with the mandrel 1, so that the mandrel 1, the roller 2 and the positioning piece 3 can be combined to form an integral printing roller, thereby completing normal printing operation.

Wherein, the driving member 34 is disposed on the shaft sleeve 32 and connected to the abutment block 33, and controls the abutment block 33 to abut against or separate from the roller 2. I.e. by operation of the driving member 34, the roller 2 is mounted or separated from the spindle 1.

In summary, when the printed pattern needs to be replaced, only the driving member 34 is controlled to separate the abutting block 33 from the roller 2, and then the roller 2 with different patterns is replaced, so that the replacement rate is effectively improved, and the cost caused by providing a plurality of integrated printing rollers can be reduced.

In addition, because the positioning disc 31 can keep relative sliding and fixing with the mandrel 1, the position of the positioning piece 3 can be adaptively adjusted in position according to the size of the roller 2, so that the requirement of the actual printing size of a product to be printed is met, and the applicability is stronger.

With continued reference to fig. 2, in this embodiment, a specific driving member 34 is further provided to rapidly control the abutment block 33 to abut against or separate from the roller 2.

The driving member 34 includes a sliding ring 341 and a hinge rod 342.

The sliding ring 341 is slidably mounted on the sleeve 32; one end of the hinge rod 342 is hinged to the abutting block 33, the other end of the hinge rod 342 is hinged to the side wall of the sliding ring 341, and the hinge rod 342 is obliquely arranged.

Specifically, when the sliding ring 341 moves in a direction approaching the abutment block 33, the abutment block 33 is pulled to move to abut against the roller 2.

And when the sliding ring 341 moves in a direction away from the abutment block 33, the abutment block 33 is pulled to move apart from the roll 2.

In summary, the contact or separation between the contact block 33 and the roller 2 can be realized by moving the sliding ring 341 along different directions, so that the operation is convenient.

In addition, the driving member 34 further includes a fixing ring 343; the fixing ring 343 is fixedly mounted on the shaft sleeve 32 and is positioned on the side of the sliding ring 341 away from the hinge rod 342.

A compression spring 344 is disposed between the fixed ring 343 and the sliding ring 341, and when the sliding ring 341 is not subjected to external force, the abutting block 33 is pulled to abut against the roller 2. That is, in a normal state, the sliding ring 341 moves independently under the compression spring 344, so that the abutting block 33 abuts against and clamps the roller 2, and the limiting effect on the roller 2 is improved.

Wherein, in order to reduce the friction resistance between the abutting block 33 and the positioning disk 31, the abutting block 33 is more stable to move, and the abutting effect between the abutting block 33 and the roller 2 is better.

The roller is arranged on one side of the abutting block 33, which is contacted with the positioning disc 31, and the inner wall of the roller 2 is provided with an abutting groove matched with the abutting block 33.

In other embodiments, the positioning disk 31 does not rotate relative to the mandrel 1 during rotational printing to ensure that the printing roller does not rotate.

A limiting block is arranged on one side, attached to the mandrel 1, of the positioning disc 31; and a limiting groove matched with the limiting block is formed in the outer wall of the mandrel 1. So that the positioning disc 31 and the mandrel 1 can only slide relatively, but cannot rotate relatively, so as to ensure the stability of the whole printing roller in the printing process.

Furthermore, the positioning disk 31 is connected with the spindle 1 for convenience and rapidity.

A threaded ring 4 is rotatably arranged on one side of the positioning disc 31 away from the shaft sleeve 32; the threaded ring 4 is in threaded connection with the mandrel 1. So that the rotation of the threaded ring 4 does not interfere with the movement of the positioning disk 31.

When the threaded ring 4 rotates, the positioning disk 31 is pulled to move axially along the mandrel 1. I.e. the adjustment of the positioning plate 31 position is completed to adapt to the installation of rollers 2 of different sizes.

In other embodiments, two positioning plates 31 are provided, and the two positioning plates 31 are symmetrically disposed along a perpendicular bisector of the mandrel 1, so as to ensure the bearing effect on the roller 2.

In addition, two positioning plates 31 are respectively positioned at the openings at the two ends of the roller 2.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
