DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides Figure 1-4 An automatic printing machine shown includes a supporting base 1, a supporting box 2 is arranged on the top of the supporting base 1, and an ink coating mechanism is arranged on the top of the front side of the supporting box 2.

[0031] Specifically, the inking mechanism includes:

[0032] The hinge seat 3 is arranged at the top of the front of the support box 2, and a placement sleeve 4 is arranged on the front of the hinge seat 3;

[0033] A downward pressing cylinder 5, which is inserted and connected to the middle part of the sliding sleeve 4 in the vertical direction, and a connecting block 6 is provided at the bottom end of the downward pressing cylinder 5;

[0034] The ink coating roller 7 is arranged at the bottom end of the connecting block 6 .

[0035] A clamping mechanism is arranged in the middle of the front side of the support base 1 , and a printed board 12 is arranged on the front side of the clamping mechanism.

[0036] It should be noted that, during the actual processing operation, the ink is delivered to the outer wall of the ink roller 7 through the delivery pipe, so that during the application process, the downward pressure cylinder 5 drives the connecting block 6 to move downward, and the connecting block 6 drives the ink roller 7 to move downward to the top of the printing plate 12 to apply the ink.

[0037] Specifically, the clamping mechanism includes:

[0038] A connecting crossbar 8, the connecting crossbar 8 is fixedly connected to the middle of the front side of the supporting box 2;

[0039] A clamping rod 9, wherein a plurality of clamping rods 9 are horizontally and centrally symmetrically arranged on the front side of the connecting cross bar 8;

[0040] The clamping baskets 10 are respectively arranged on one side opposite to the clamping rods 9 , and two ends of the printing plate 12 are respectively sleeved between the opposite ends of the clamping baskets 10 .

[0041] Furthermore, a connecting slide bar 801 is provided on the top of the connecting cross bar 8, one end of the clamping rod 9 is slidably mounted on the outer wall of the connecting slide bar 801, and a pressing bolt 11 for pressing down the printing plate 12 is inserted and connected through the top thread of the clamping basket 10.

[0042] Furthermore, a pattern plate 1201 is provided in the middle of the printing plate 12 .

[0043] It should be noted that by screwing the downward bolt 11 on the top of the clamping basket 10, the two ends of the printing plate 12 are squeezed and fixed. This method also facilitates the replacement of the printing plate 12, so that the pattern plate 1201 can be replaced so that the printed pattern can be replaced. In actual use, a horizontal and transverse reciprocating pushing mechanism can be provided at the connection between the clamping rod 9 and the connecting cross bar 8. Under such operation, the printing plate 12 can be pushed to move horizontally and transversely, so that the pattern at the pattern plate 1201 can be rolled onto the surface of the cylindrical product.

[0044] The bottom of the front side of the support box 2 is provided with a placement mechanism for clamping columnar printed matter, and the placement mechanism includes:

[0045] A lifting cylinder 14, which is arranged at the bottom of the front side of the supporting box 2;

[0046] The placing plate 13 is fixedly connected to the output end of the lifting cylinder 14 , and a fixed bracket and a sliding bracket are respectively arranged on the top of the placing plate 13 , and a traction mechanism is arranged between the two ends of the sliding bracket and the two sides of the placing plate 13 .

[0047] Specifically, the fixed bracket includes a fixing bar 1301, which is fixedly connected to the top of the placement plate 13 and is located at one end close to the support box 2. The front side of the fixing bar 1301 is rotatably interlaced with multiple first rollers 1302. A rotation groove is opened on the front side of the fixing bar 1301, and a connecting rotating rod is provided between the first roller 1302 and the rotation groove, so that the first roller 1302 can rotate smoothly.

[0048] Specifically, the sliding bracket includes a sliding bar 15, which is slidably connected to the top of the placement plate 13, and the back of the sliding bar 15 is rotatably interlaced with a second roller 1501. The connection between the second roller 1501 and the sliding bar 15 is the same as the connection between the first roller 1302 and the fixed bar 1301, and the top-view cross-sections of the first roller 1302 and the second roller 1501 are both "convex" shapes, and both ends of the sliding bar 15 are provided with connecting slides 1502 for connecting the traction mechanism.

[0049] Furthermore, connecting grooves are provided on both sides of the placement plate 13, and the traction mechanism includes a guide slide bar 16, the two ends of which are fixedly connected to the inner walls of the front and back sides of the connecting groove, respectively. The bottom of the connecting slide plate 1502 is slidably sleeved on the outer wall of the guide slide bar 16, and a traction spring 17 is provided on the outer wall of the guide slide bar 16 and at one end located on the back side. The two ends of the traction spring 17 are fixedly connected to the inner wall of the back side of the connecting groove and the back side of the bottom of the connecting slide plate 1502, respectively.

[0050] It should be noted that when clamping the cylindrical product to be printed, the sliding bar 15 is first pulled in the direction away from the fixed bar 1301. At this time, the sliding bar 15 drives the connecting slide 1502 to move synchronously. The connecting slide 1502 stretches the traction spring 17 during the movement. After the horizontal longitudinal spacing between the first roller 1302 and the second roller 1501 exceeds the length of the cylindrical product to be printed, the product is placed between the tops of the first roller 1302 and the second roller 1501. Since there are multiple first rollers 1302 and second rollers 1501, the product is placed between multiple first rollers 1302 and second rollers 1501. In this way, when the product is pressed down for printing, it can rotate through the moving roller pressure of the pattern plate 1201, and then the pattern is rolled on the surface of the product. After the product is placed, the pull on the sliding bar 15 is released. At this time, under the traction of the restoring force of the traction spring 17, the sliding bar 15 moves in the direction close to the fixed bar 1301, thereby cooperating to complete the clamping of the product.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
