As shown in fig. 2 to 11, the present invention provides a number printing device, which includes a printing roller assembly 200 and a mounting seat, wherein a plurality of number blocks 240 are mounted on a working surface of the printing roller assembly 200; the mounting seat comprises a mounting seat body 300, a sliding rod 320, a sliding block 330 and an elastic piece 340, wherein a receiving groove 316 for inserting the printing roller assembly 200 is formed in the middle of the mounting seat body 300, and a first through hole 313 and a second through hole 314 which are communicated with the receiving groove 316 and coaxial with each other are respectively formed in two sides of the top of the mounting seat body 300; a limiting part 321 is formed at a first end of the sliding rod 320, and a second end of the sliding rod passes through the first through hole 313, the accommodating groove 316 and the second through hole 314 in sequence and then is connected with the locking part 322; the elastic element 340 is sleeved on the sliding rod 320, and the elastic element 340 is abutted on the limiting portion 321 and used for driving the sliding rod 320 to move along the direction from the second through hole 314 to the first through hole 313; the sliding block 330 is slidably sleeved on the sliding rod 320, one end of the sliding block 330 abuts against the locking member 322, and the other end of the sliding block 330 is provided with a guide inclined surface for guiding the printing roller assembly 200 to be inserted; the bottom of the printing roller assembly 200 is provided with an avoiding hole for the sliding rod 320 to pass through.

Because each processing shift has a fixed character number corresponding to the processing shift, in order to improve the production efficiency, each processing shift can be provided with one printing roller assembly 200, and each printing roller assembly 200 is provided with a character number block 240 matched with the shift, so that the whole printing roller assembly 200 is only required to be replaced when the processing shift is replaced, and the mounting seat does not need to be detached. Specifically, the method comprises the following steps:

taking the orientation in fig. 3 as an example, when the printing roller assembly 200 is installed, the printing roller assembly 200 is gradually inserted into the receiving slot 316 from the top to the bottom. During the extension of the print roller assembly 200 into the receiving slot 316, the slider 330 is positioned on one side of the print roller assembly 200, and the bottom of the print roller assembly 200 moves down the guide ramp and presses the slider 330. Since the sliding block 330 abuts against the locking member 322, the sliding block 330 pushes the sliding bar 320 to move in the direction from the first through hole 313 to the second through hole 314 during the downward movement of the printing roller assembly 200. As the sliding rod 320 moves, the spacing between the limiting portion 321 of the sliding rod 320 and the mounting base body 300 becomes smaller, and the elastic member 340 is gradually compressed. When the printing roller assembly 200 is inserted in place, the compressed elastic member 340 applies a pushing force, i.e. a restoring force, to the sliding rod 320, wherein the pushing force is directed from the second through hole 314 to the first through hole 313, so as to drive the sliding block 330 to abut against the printing roller assembly 200. When the printing roller assembly 200 is disassembled, the limiting portion 321 of the sliding rod 320 is pressed, so that the sliding rod 320 moves along the direction from the first through hole 313 to the second through hole 314 under the action of external force, the length of the sliding rod 320 extending out of the mounting seat body 300 through the second through hole 314 increases, the sliding block 330 is not restrained by the locking member 322 any more, and at this time, the printing roller assembly 200 can be easily pulled out of the mounting seat body 300.

As can be seen from the above, in the print number device, the sliding rod 320 passing through the receiving slot 316 is inserted into the mounting base body 300, and the elastic member 340 and the sliding block 330 are respectively sleeved at the two ends of the sliding rod 320, so that the sliding block 330 can be driven to abut against the printing roller assembly 200 by the elastic force of the elastic member 340 when the printing roller assembly 200 is inserted, and the restriction of the sliding block 330 on the printing roller assembly 200 can be released by pressing the limiting portion 321 of the sliding rod 320 when the printing roller assembly 200 is detached, so that the printing roller assembly 200 can be easily pulled out from the mounting base body 300. Therefore, in the whole replacing process, a worker only needs to press the sliding rod 320 and the plug-pull printing roller assembly 200, the operation is very convenient, and the replacing efficiency is obviously improved. In addition, the sliding block 330 is automatically abutted against the printing roller assembly 200 by virtue of the restoring force of the elastic piece 340, and the adjustment by workers is not needed, so that the safety is greatly improved.

As shown in fig. 9, the sliding block 330 includes a sliding column 335, the sliding column 335 is axially provided with a through hole for passing the sliding rod 320 therethrough, an end surface of the sliding column 335 facing the first through hole 313 is formed with a guiding inclined surface, the guiding inclined surface includes an upper inclined surface 331 and a lower inclined surface 332, the upper inclined surface 331 is expanded from top to bottom, and the lower inclined surface 332 is expanded from bottom to top; the side wall of the end part of the sliding column 335, which faces away from the first through hole 313, is formed with a limiting boss 333, and the limiting boss 333 is arranged between the locking member 322 and the mounting seat body 300 and is used for interference fit with the locking member 322 and the mounting seat body 300.

The advantages of such an arrangement are: on one hand, compared with the case that the end surface of the sliding column 335 is not provided with the lower inclined surface 332, by providing the lower inclined surface 332 on the end surface of the sliding column 335, when the sliding column 335 abuts against the printing roller assembly 200, the sliding column 335 abuts against the printing roller assembly 200 by using the joint of the upper inclined surface 331 and the lower inclined surface 332 thereof, and thus the length of the sliding column 335 extending into the accommodating groove 316 can be reduced, that is, the gap between the printing roller assembly 200 and the upper inclined surface 331 can be reduced. On the other hand, the limiting boss 333 can prevent the sliding block 330 and the locking member 322 from sliding out of the second through hole 314 and entering the accommodating groove 316 due to the overlarge pushing force applied to the sliding rod 320 by the elastic member 340 after the printing roller assembly 200 is pulled out of the mounting seat and the sliding rod 320 loses the external force for pressing. Specifically, the method comprises the following steps:

when the printing roller assembly 200 is pulled out from the mount body 300 and the pressing of the slider 320 is released, the compressed elastic member 340 applies a pushing force to the slider 320, and the slider 320 moves in a direction from the second through hole 314 to the first through hole 313 by the pushing force. During the movement of the sliding bar 320, the locking member 322 fixed on the sliding bar 320 pushes the sliding block 330 to move together. Due to the existence of the limit boss 333, after the sliding column 335 moves a certain distance, the limit boss 333 will abut against the mounting seat body 300, and meanwhile, the locking member 322 will abut against the limit boss 333, so that the sliding block 330 and the locking member 322 can be prevented from sliding out of the second through hole 314.

It should be noted that the sliding rod 320 and the locking member 322 can be connected by screw threads or can be clamped. When the sliding rod 320 is connected with the locking member 322 through threads, the side wall of one end of the sliding rod 320, which is far away from the limiting portion 321, is provided with external threads, and the locking member 322 is provided with internal threads matched with the external threads. Of course, the sliding rod 320 may be directly formed of a bolt, in which case the locking member 322 is a nut and the limiting portion 321 is a head of the bolt.

Furthermore, the bottom surface of the sliding column 335 is formed with an anti-rotation groove 334 parallel to the axial direction of the sliding rod 320, the inner wall of the second through hole 314 is provided with a jack penetrating through the mounting seat body 300, an anti-rotation member is fixed in the jack, and the end of the anti-rotation member extends out of the jack and is in sliding fit with the anti-rotation groove 334. The advantages of such an arrangement are: on the one hand, can avoid slider 330 to slide in-process and take place to rotate and influence the direction effect of direction inclined plane to printing roller subassembly 200, specifically, because the tip that prevents changeing stretches into anti-rotating groove 334, when consequently slider 330 has the pivoted trend, receives preventing changeing blockking of preventing changeing, prevents that changeing can't be crossed to anti-rotating groove 334, and then just can avoid slider 330 to rotate. On the other hand, the sliding fit of the rotation preventing member and the rotation preventing groove 334 can guide the movement of the slider 330. The rotation-preventing member may be, but is not limited to, a screw. When the anti-rotation member is a screw, the end of the screw is slidably inserted into the anti-rotation slot 334, and the receptacle is a threaded hole that mates with the screw.

Further, as shown in fig. 7, the first through hole 313 is a stepped hole, a large end of the stepped hole faces the limiting portion 321, and two ends of the elastic element 340 respectively abut against the limiting portion 321 and a stepped surface of the stepped hole. The first through hole 313 may be a straight hole, in addition to a stepped hole. Taking the elastic element 340 as a spring as an example, when the first through hole 313 is a straight hole, the inner diameter of the first through hole 313 is smaller than the outer diameter of the spring, that is, two ends of the spring respectively abut against the mounting base body 300 and the limiting portion 321. Of course, compare in the condition that first through-hole 313 is the straight hole, under the prerequisite that the length of guaranteeing the spring is the same with compression degree, set up first through-hole 313 into the shoulder hole, can make partly major end that stretches into the shoulder hole of spring, and then just can reduce the length of slide bar 320 for whole mount pad body 300 is compacter.

Considering that the existing embossed block 240 is a cuboid structure, the directions of letters and numbers on the upper surface of the embossed block 240 need to be carefully checked during installation, so that the time for replacing the embossed block 240 is virtually prolonged, and in actual operation, a worker is very easy to mistakenly install the directions of the embossed block 240, so that the printed numbers are wrong, and the product quality is affected, therefore, in order to avoid the above problems, as shown in fig. 2, 4 and 6, the side wall of the accommodating groove 316 is provided with a first guide part; the printing roller assembly 200 comprises a font support plate 210, a first clamping plate 220 and a second clamping plate 230, wherein the font support plate 210 is clamped between the first clamping plate 220 and the second clamping plate 230 through bolts; one side of the number support plate 210 facing the first clamping plate 220 is provided with a second guide portion 211 used for being in sliding fit with the first guide portion, the second guide portion 211 exposes the first clamping plate 220, a mounting groove 212 used for mounting a number block 240 is formed in the working surface of the number support plate 210, a first inserting section 213 and a first inserting portion 221 are respectively formed on the opposite surfaces of the number support plate 210 and the first clamping plate 220, a second inserting section 241 is formed on one side of the number block 240 facing the first clamping plate 220, and the first inserting section 213 and the second inserting section 241 are spliced to form a second inserting portion used for being matched with the first inserting portion 221.

One of the first guide part and the second guide part 211 is a guide key, and the other is a guide groove, that is, when the first guide part is a guide key, the second guide part 211 is a guide groove; when the first guide portion is a guide groove, the second guide portion 211 is a guide key. Further, one of the first inserting-connecting part 221 and the second inserting-connecting part is a convex strip, and the other one is a groove, and similarly, when the first inserting-connecting part 221 is a convex strip, the second inserting-connecting part is a groove; when the first inserting-connecting part 221 is a groove, the second inserting-connecting part is a convex strip. Taking the second inserting portion as a groove as an example, the first inserting section 213 is a multi-section concave strip, the multi-section concave strip and the plurality of mounting grooves 212 are alternately arranged at intervals, that is, the mounting grooves 212 are formed between the adjacent two end concave strips, and the second inserting section 241 inserted into the number block 240 in the mounting groove 212 is a notch.

The following description will be given by taking the first guide portion as a guide groove, the second guide portion 211 as a guide key, the first inserting portion 221 as a convex strip, and the second inserting portion as a concave groove, as an example, to illustrate the use method of the printing number device in the embodiment of the present invention:

It can be seen that during the whole installation process, a worker does not need to check the directions of letters and numbers on the surface of the font block 240, during the installation process, as long as the first clamping plate 220 and the second clamping plate 230 can clamp the font block 240 on the font support plate 210, the font block 240 is not installed reversely, and meanwhile, as long as the printing roller assembly 200 can be installed in the installation seat, the printing roller assembly 200 is not installed reversely, so that the problem of wrong installation of the font block 240 in the direction is fundamentally solved, and the efficiency of replacing the font block 240 is improved.

As shown in fig. 3, 7 and 8, the mount body 300 includes a first support plate 311, a second support plate 312 and a base 310, the first support plate 311 and the second support plate 312 are fixed on the base 310 by a first fastener 370, and an upper semicircular hole 317 is formed on one side of the first support plate 311 and the second support plate 312 facing the base 310; a lower semicircular hole 318 is formed on one side of the base 310 facing the mounting seat body 300, and the upper semicircular hole 317 and the lower semicircular hole 318 enclose together to form an axle hole; the first support plate 311 is connected with the second support plate 312 through a second fastener 315, and a recessed area is formed on one side of the first support plate 311 facing the second support plate 312 so as to form an accommodating groove 316 together with the second support plate 312; first and second through holes 313 and 314 are formed at the tops of the first and second support plates 311 and 312, respectively. The first support plate 311 and the second support plate 312 may be in an arch structure, that is, the projection shape of the arch structure on the vertical plane is similar to "Ω". When the side wall of the receiving groove 316 is provided with the first guiding portion, the first guiding portion is formed on one side of the first support plate 311 facing the second support plate 312.

Further, as shown in fig. 11 and 8, the mounting base body 300 further includes an adjusting bolt 360, the base 310 is longitudinally penetrated with a threaded hole 319 for mounting the adjusting bolt 360, the threaded hole 319 is communicated with the receiving groove 316, and the top of the adjusting bolt 360 protrudes out of the threaded hole 319 for abutting against the bottom surface of the printing roller assembly 200.
