Description

This invention relates to an improvement in the structure of a printing roller for printing.

There is always a demand from consumers to beautify the packaging of goods. To meet this demand, printers apply fully automatic molding machines to produce various types of paper boxes and paper bags at high speed. In order to meet the vast needs of the market, a considerable number of roller molding presses have appeared on the market. This requires the use of different sized moldings, different thickness printing paper materials, and different diameter printing rollers for different printing stresses in order to achieve high speed automated production.

Most conventional molding roller structures are constructed by combining a plate cylinder with an inner roller shaft. However, the number of related parts is extremely large and the structure is complicated. When exchanging the plate cylinder, bolts, pins, sleeves, bearing mounting seats, locking devices, etc. must be removed one by one by experienced engineers. After replacing the plate cylinder, it must be installed in the reverse order, and further calibration must be performed after the installation is complete in order to improve printing accuracy and quality.

FIG. 1 discloses a printing roller set 1 currently on the market. The structure of the printing roller disclosed in the drawings is simplified compared to the earlier printing roller used before. However, in the process of removing the plate cylinder 10, the plate cylinder 10 can be removed only after the bolts 11 and the positioning pins 12 are removed and the stopper plate 13, the stopper ring 14 and the like are removed. In this way, when there are many parts, time and labor are required for the replacement work, and the reliability of the entire machine is also reduced, and an error easily occurs when printing. This can affect print quality and can cause the machine to stop severely.

An object of the present invention is to provide a structure of a printing roller that can be easily removed and quickly performed when the printing roller is replaced.

Therefore, as a result of intensive research in view of the drawbacks found in the prior art, the present inventor has obtained a left fixed seat, a right fixed seat, the left fixed seat, a printing roller that passes through the right fixed seat, and the A bearing provided on the outside of the left fixed seat, and the left fixed seat and the right fixed seat each have a through hole for positioning by inserting the printing roller, and the left fixed seat A screw hole is drilled around the through-hole to be drilled, and the bolt is inserted, and the printing roller includes an internal rotary rod and a copper plate, and the internal rotary rod and one end of the plate cylinder are Fine adjustment means for adjusting the relative position between the plate cylinder and the internal rotary rod and increasing printing accuracy is provided, the bearing is connected to the printing roller by a concentric shaft, and further, a bearing metal, packing , Collar, sleeve, contact shaft, and two ears on the outer peripheral surface of the bearing Is formed by forming a hook-shaped hole having a large and small circle connected to the ear, and inserting a bolt into a screw hole formed around the hole and the through hole of the left fixing seat. The present invention has been completed based on such knowledge, focusing on the point that the problem can be solved by the structure of the roller.

Is formed with a bowl-like hole portion in which large and small circles are connected, and a bolt is inserted into a screw hole formed around the hole portion and the through hole of the left fixed seat.

The structure of the printing roller according to claim 2 is a structure in which a plurality of lock grooves are formed in the internal rotary rod in claim 1 to provide a lock member, and an engagement groove is formed at a corresponding position on the inner wall of the plate copper. Then, the printing roller and the internal rotary rod 31 are engaged with each other so that the print roller rotates in conjunction with the operation of the internal rotary rod.

The structure of the printing roller according to claim 3 forms a scale for fine adjustment in the axial direction of the printing roller on the outer peripheral surface of one end of the sleeve according to claim 1.

The structure of the printing roller of the present invention is advantageous in that the printing roller can be quickly replaced by a simple operation and the quality and accuracy of printing are improved.

The present invention provides an improvement in the structure of a printing roller, comprising a left fixed seat, a right fixed seat, a printing roller that passes through the left fixed seat, and the right fixed seat, and the left fixed seat. The left fixed seat and the right fixed seat each have a through hole for positioning by inserting the printing roller, and the left fixed seat has a through hole formed in the left fixed seat. A screw hole is drilled around the hole, and the bolt is inserted. The printing roller includes an internal rotary rod and a plate copper. The internal rotary rod and one end of the plate cylinder have the plate cylinder and Fine adjustment means for adjusting the relative position with the internal rotary rod and increasing the printing accuracy is provided, the bearing is connected to the printing roller by a concentric shaft, and further, a bearing metal, a paxig, a collar, and a sleeve Each of the contact shafts, and two ears are formed on the outer peripheral surface of the bearing. The ear portion is provided with a bowl-shaped hole portion in which different sizes of circles are connected, and a bolt is inserted through the hole portion and a screw hole formed around the through hole of the left fixed seat to constitute a printing roller. As a result, the purpose of enabling quick replacement of the printing roller with a simple operation has been realized.
The printing roller having such a configuration will be described below with reference to specific examples in order to describe the structure and features in detail.

As shown in FIG. 2, the printing roller set 2 according to the present invention includes at least a left fixing seat 20 and a right fixing seat 21, and each of the fixing seats is inserted with a printing roller for positioning. Through holes 201 and 211 are formed. Further, a screw hole 202 is formed around the through hole 201 formed in the left fixed seat 20, and a bolt 203 is inserted.

The printing roller 30 that passes through the left fixed seat 20 and the right fixed seat 21 includes an internal rotary rod 31 and a copper plate 32. A plurality of lock grooves 311 are formed in the internal rotary rod 31 and a lock member 312 is provided. An engagement groove 321 is formed at a corresponding position on the inner wall of the plate copper 32. With such a structure, the printing roller 30 and the internal rotary rod 31 are engaged, and the print roller 30 rotates in conjunction with the operation of the internal rotary rod 31.

A complete printing roller is configured by attaching related members such as a lifting mechanism for engaging the printing roller 30 and the internal rotary rod 31, and a separate collar and packing. Further, fine adjustment means 33 is provided at one end of the internal rotary drum 31 and the plate cylinder 32 to adjust the relative positions of the plate cylinder 32 and the internal rotary rod 31 so as to increase the printing accuracy.
