Description

Technical Field

[0001] The utility model relates to the technical field related to underwear processing, and in particular to an underwear label printing machine. Background Art

[0002] Printed labels or care labels are one of the printing methods used in the printing industry. Compared with offset printing, they are simpler and are commonly used on clothing, shoes, hats, underwear, quilts, and other daily necessities or textiles. They are used to let customers know the material composition and washing standards of the product.

[0003] Because the care label sewn on underwear may cause discomfort to the wearer, such as harassment, stinging and other discomfort, underwear manufacturers print the information on the care label directly on the underwear, which allows customers to know the product ingredients, washing standards, etc., without causing discomfort to the wearer.

[0004] When the existing label printing machine is in use, the operator is required to lay the area of ​​the underwear to be printed on the support plate. Because the knitted fabric is highly deformable, the operator is required to apply force to the underwear so that the area of ​​the underwear to be printed is in a tensioned state to avoid label printing failure caused by wrinkles in the underwear. However, the tension force is manually applied to the underwear, and the tension degree of each underwear is different. After the label printing is completed, the shrinkage of the underwear will cause the printed label pattern to deform. Different tension forces will cause the printed label pattern on each underwear to deform and shrink to different degrees. Therefore, it is necessary to design an underwear label printing machine. Utility Model Content

[0005] In view of the above technical problems, the purpose of the utility model is to overcome the problem in the prior art that manually tensioning the area to be printed on the underwear will result in different tension levels for each underwear, which will affect the deformation degree of the printed label pattern when the label is printed.

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0026] like Figure 1-3 As shown, a underwear label printing machine comprises: a mounting plate 1, a label printing machine body mounted on the mounting plate 1, a horizontal support plate 3 mounted on the mounting plate 1 through a first mounting frame 2, and a vertical moving mechanism mounted on the mounting plate 1, wherein a pair of parallel strip grooves 4 are recessed on the upper surface of the support plate 3, and a pair of positioning units respectively located above the corresponding strip grooves 4 are mounted on the output end of the vertical moving mechanism;

[0027] The positioning unit includes a horizontal pressing arm 5 which is arranged parallel to the strip groove 4 and can be pressed on the support plate 3, and a tensioning arm 6 which is fixedly connected to the output end of the vertical moving mechanism through a connecting mechanism and can be located directly above the corresponding strip groove 4 and parallel to the pressing arm 5 and behind the pressing arm 5 to contact the underwear. The pressing arm 5 is connected to the connecting mechanism through an elastic mounting mechanism, and the pressing arm 5 is located on the side of the corresponding strip groove 4 away from the other strip groove 4.

[0028] The main body of the label printing machine is an existing mature technology, and the structure and working principle will not be elaborated in this article.

[0029] When it is necessary to print a label on the underwear, the underwear is put on the support plate 3, and the part of the underwear that contacts the upper surface of the support plate 3 is spread out flat. The vertical moving mechanism drives a pair of positioning units to move vertically downward, driving the pressing arm 5 to press on the underwear first, and the output end of the vertical moving mechanism continues to move downward, which will drive the tensioning arm 6 to continue to move downward. When the tensioning arm 6 enters the strip groove 4, the area of ​​the underwear to be printed can be tightened, which is convenient for the main body of the printing machine to print the label.

[0030] The positioning unit presses and tightens the area of ​​the underwear to be printed, so that the tension of each underwear is consistent. After the positioning unit releases the underwear, the shrinkage degree of several underwear is the same, and the shrinkage and deformation degree of the printed label patterns on several underwear is the same, thereby improving the overall quality of the printed label.

[0031] When the pressing arm 5 is pressed downward to cooperate with the supporting plate 3 to clamp the underwear, the operator can loosen the underwear, pick up the next underwear to be printed, and find the underwear to be printed. After the underwear printing on the supporting plate 3 is completed, the underwear in the supporting plate 3 can be removed, and the underwear in the operator's hand can be directly put on the supporting plate 3, which can make full use of the underwear printing time to prepare for the next underwear printing, thereby improving work efficiency.

[0032] The elastic mounting mechanism includes a plurality of guide bolts 7 which vertically slide through the connecting mechanism and whose lower ends are fixedly connected to the pressure arm 5, and a plurality of return springs 8 which are correspondingly sleeved on the plurality of guide bolts 7, and the two ends of the return springs 8 respectively contact the pressure arm 5 and the connecting mechanism.

[0033] When the pressing arm 5 contacts the underwear and cooperates with the support plate 3 to clamp the underwear, the output end of the vertical moving mechanism continues to drive the connecting mechanism to move downward, driving the tensioning arm 6 to contact the underwear. At this time, the pressing arm 5 is fixed, and the connecting mechanism slides vertically downward on the guide bolt 7, and the reset spring 8 is further compressed; when the printing of the mark is completed, the output end of the vertical moving mechanism drives the positioning unit to move vertically downward, and the reset spring 8 will push the pressing arm 5 to slide downward relative to the connecting mechanism, pushing the pressing arm 5 to return to its original position. When the pressing arm 5 is in the reset state, it is located below the corresponding tensioning arm 6.

[0034] The lower surface of the pressing arm 5 is equipped with a rubber strip 9 .

[0035] The connection mechanism includes a horizontal mounting arm 10 fixedly connected to the vertical movement output end and a first connecting frame 11 fixedly connected to at least the mounting arm 10 and connected to the top of the tensioning arm 6 .

[0036] The output end of the vertical movement mechanism drives the tensioning arm 6 to move vertically through the mounting arm 10 and the first connecting frame 11 .

[0037] The cross section of the tensioning arm 6 is circular.

[0038] After the tensioning arm 6 contacts the underwear and continues to move downward, there will be sliding between the tensioning arm 6 and the underwear. The cross section of the tensioning arm 6 is circular, which can reduce the sliding friction between the tensioning arm 6 and the underwear.

[0039] The mounting arm 10 is located directly above the pressing arm 5, and a limiting mechanism is installed on the top of the pressing arm 5;

[0040] The limiting mechanism includes a support arm 12 hinged to the pressure arm 5 through a hinge axis whose length direction is perpendicular to the length direction of the pressure arm 5, a sliding member 13 slidably installed on the pressure arm 5 along the length direction of the pressure arm 5, a connecting rod 14 whose two ends are respectively hinged to the middle part of the support arm 12 and the sliding member 13, a threaded sleeve 15 fixedly installed on the pressure arm 5, and an adjusting bolt 16 threadedly passing through the threaded sleeve 15 and the end of which is axially connected to the sliding member 13.

[0041] The function of the limiting mechanism is to control the distance that the tensioning arm 6 continues to move downward after the pressing arm 5 is pressed on the underwear, that is, to adjust the depth of the tensioning arm 6 inserted downward into the strip groove 4. After the mounting arm 10 contacts the supporting arm 12, the supporting arm 12 can intercept the mounting arm 10 from continuing to move downward.

[0042] By rotating the adjusting bolt 16 , the sliding member 13 can slide on the mounting arm 10 , and the sliding member 13 drives the supporting arm 12 to rotate through the connecting rod 14 , thereby adjusting the distance between the upper end of the supporting arm 12 and the pressing arm 5 .

[0043] The vertical moving mechanism includes a vertical cylinder 17 fixedly assembled on the lower surface of the mounting plate 1 through a second mounting frame, a connecting piece fixedly connected to the output end of the cylinder 17, and a pair of guide rods 18 respectively located on both sides of the support plate 3 and vertically sliding through the mounting plate 1 and fixedly connected to the connecting piece, and the upper end of each guide rod 18 is fixedly connected to a second connecting frame 19 fixedly connected to the connecting mechanism.

[0044] The output end of the cylinder 17 drives two guide rods 18 to slide vertically on the mounting plate 1 through a connecting piece, and each guide rod 18 drives the corresponding positioning unit to move vertically through a second connecting frame 19 .

[0045] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
