Abstract

This utility model provides an automatic lettering machine specifically for non-standard sleeves, belonging to the field of sleeve processing technology. It addresses the problems of existing lettering machines where the letter molds are mostly rigidly fixed with bolts, requiring tools for disassembly and assembly, and lacking a precise adjustment mechanism for the relative position of the letter mold and the turntable. These issues easily lead to lettering misalignment and compatibility failure when processing non-standard sleeves. The machine includes a main body, a first slider, a limiting box, an adjustment component, and a quick-change component. The first slider is slidably connected inside a fixed box; the limiting box is fixedly connected above a positioning box; the adjustment component is located inside the fixed box; and the quick-change component is located above the first slider. This utility model achieves precise adjustment of the letter mold height and the distance between it and the turntable, meeting the precise lettering requirements for non-standard sleeves. The quick-change component enables tool-free loading and unloading of the letter mold, significantly reducing mold change time when changing models, providing an efficient solution for small-batch customized production of non-standard sleeves.

Description

Technical Field

[0001] This utility model belongs to the field of sleeve processing technology, and more specifically, it relates to an automatic lettering machine for non-standard sleeves. Background Technology

[0002] At the end of the sleeve processing, the automatic lettering machine uses the extrusion of the lettering die onto the sleeve surface and the plastic deformation of the metal (or some plastic) to "imprint" the lettering die onto the sleeve surface, forming a permanent mark. This marks the sleeve model for easy identification and use. Existing automatic lettering machines for sleeves generally consist of the lettering machine body, turntable, drive system, and lettering die.

[0003] Based on the above, the lettering molds of rolling machines are mostly rigidly fixed by bolts. When changing the sleeve model or dealing with non-standard sleeves, on the one hand, bolt disassembly and assembly require tools, and the lettering mold replacement process is cumbersome and time-consuming, which seriously affects the efficiency of changeover. On the other hand, the relative position between the lettering mold and the turntable, such as radial spacing and axial height, lacks a precise adjustment mechanism. Due to the differences in diameter and length of non-standard sleeves, the engraving position needs to be finely adjusted, while the traditional structure can only be adjusted by simple shims, making it difficult to control the accuracy, resulting in engraving offset and adaptation failure. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automatic lettering machine specifically designed for non-standard sleeves. This addresses the issue that existing lettering machines often use bolts for rigid fixing of the letter molds. When changing sleeve models or processing non-standard sleeves, on the one hand, bolt installation and removal require tools, making the letter mold replacement process cumbersome and time-consuming, severely impacting changeover efficiency. On the other hand, the relative positions of the letter mold and the turntable, such as radial spacing and axial height, lack precise adjustment mechanisms. Due to differences in diameter and length, non-standard sleeves require fine adjustments to the engraving position, while traditional structures can only adjust using simple shims, making precision difficult to control and leading to engraving misalignment and compatibility failure.

[0005] The purpose and effect of this utility model, a special automatic lettering machine for non-standard sleeves, are achieved by the following specific technical means:

[0006] An automatic lettering roller for non-standard sleeves includes a roller machine body, a turntable, a fixed box, a first slider, a positioning box, a limit box, letter molds, an adjustment component, and a quick-change component. The turntable is rotatably connected above the roller machine body. The fixed box is fixedly connected above the roller machine body. The first slider is slidably connected inside the fixed box. The positioning box is positioned above the first slider. The limit box is fixedly connected above the positioning box. The letter molds are inserted into the positioning box. The adjustment component is positioned inside the fixed box. The quick-change component is positioned above the first slider.

[0007] Furthermore, the adjustment assembly includes: a first adjusting screw and a first adjusting knob; the first adjusting screw is rotatably connected inside the fixed box, and the first adjusting screw is threadedly connected to the first slider; the first adjusting knob is coaxially fixedly connected to the top of the first adjusting screw.

[0008] Furthermore, the adjustment assembly also includes: a second transmission screw, a second adjustment knob, and a second slider; the second transmission screw is rotatably connected inside the first slider; the second adjustment knob is coaxially fixedly connected to the left end of the second transmission screw; the second slider is slidably connected inside the first slider, the second slider is threadedly connected to the second transmission screw, and the second slider is fixedly connected to the lower left end of the positioning box.

[0009] Furthermore, the quick-change component includes: a limit knob, a transmission gear, and a transmission rack; the limit knob is rotatably connected inside the limit box; the transmission gear is coaxially fixedly connected to the bottom of the limit knob; two transmission racks are provided, and the two transmission racks are slidably connected inside the limit box, and the two transmission racks respectively mesh with the transmission gear.

[0010] Furthermore, the quick-change assembly also includes: a T-block and a positioning pin; two T-blocks are provided, and the two T-blocks are respectively fixedly connected to the outer side of two transmission racks; two positioning pins are provided, and the two positioning pins are respectively fixedly connected to the inner side of the bottom of the two T-blocks.

[0011] Furthermore, the quick-change assembly also includes: a spiral spring and a positioning groove; the inner end of the spiral spring is coaxially fixedly connected to the outside of the limiting knob, and the outer end of the spiral spring is coaxially fixedly connected to the inside of the limiting box; the positioning groove is formed inside the character mold.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] First, by setting up adjustment components, the problem of the lack of a precise adjustment mechanism for the relative position of the letter mold and the turntable in traditional rolling lettering machines is solved. The height of the letter mold and the distance between it and the turntable can be finely adjusted through a threaded transmission mechanism, making the adjustment accuracy controllable. This adapts to the different needs of non-standard sleeve diameter and length, avoids lettering offset and adaptation failure, and improves the equipment's adaptability to non-standard sleeves.

[0014] Secondly, by adding a quick-change component, the problems of cumbersome disassembly and low changeover efficiency of the traditional bolt-fixed type mold are solved. The gear and rack transmission drives the positioning pin to quickly insert and remove, realizing tool-free quick loading and unloading of type molds, which greatly shortens the changeover time and improves production efficiency. It is especially suitable for scenarios such as non-standard sleeve processing where sleeve models change frequently.

[0015] This invention enables precise adjustment of the character mold height and the distance between it and the turntable, adapting to the precise rolling requirements of non-standard sleeves, greatly reducing the risk of engraving deviation. The character mold can be installed and removed without tools by quickly changing components, significantly shortening the mold change time when changing models, and providing an efficient solution for small-batch customized production of non-standard sleeves.

[0030] The specific usage and function of this embodiment are as follows: When in use, if the model of the sleeve to be processed changes, rotating the first adjustment knob 501 will drive the first slider 4 to move up and down through the threaded transmission mechanism formed by the first adjustment screw 5 and the first slider 4, thereby adjusting the height of the letter mold 9, which is convenient for adjusting the rolling height of the sleeve; rotating the second adjustment knob 601 will drive the positioning box 701 to move left and right through the threaded transmission mechanism formed by the second slider 7 and the second transmission screw 6, thereby adjusting the distance between the letter mold 9 and the turntable 2, which is convenient for rolling sleeves with different diameters, and the adjustment distance is more precise, which is suitable for rolling non-standard sleeves.

[0031] Example 2:

[0032] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes a quick-change component, which is located above the first slider 4.

[0033] The quick-change component includes: a limit knob 10, a transmission gear 1001, and a transmission rack 11; the limit knob 10 is rotatably connected inside the limit box 8; the transmission gear 1001 is coaxially fixedly connected to the bottom of the limit knob 10; two transmission racks 11 are provided, and the two transmission racks 11 are slidably connected inside the limit box 8, and the two transmission racks 11 are respectively engaged with the transmission gear 1001.

[0034] The quick-change assembly also includes: a T-block 1101 and a positioning pin 1102; two T-blocks 1101 are provided, and the two T-blocks 1101 are respectively fixedly connected to the outer side of the two transmission racks 11; two positioning pins 1102 are provided, and the two positioning pins 1102 are respectively fixedly connected to the inner side of the bottom of the two T-blocks 1101.

[0036] The specific usage and function of this embodiment: When the shape of the characters to be rolled on the sleeve changes and a new character mold 9 needs to be replaced, the limit knob 10 is rotated counterclockwise. The gear and rack transmission mechanism, which is formed by the two transmission racks 11 meshing with the transmission gear 1001, drives the two sets of T-blocks 1101 and positioning pins 1102 to move outwards at the same time, so that the positioning pins 1102 disengage from the positioning grooves 901 inside the character mold 9. Then, the character mold 9 can be removed by moving it to the right. The new character mold 9 is taken out and inserted into the positioning box 701. The limit knob 10 is released. At this time, the spiral spring 1002, which was tightened when the limit knob 10 was rotated counterclockwise, rebounds and drives the limit knob 10 to rotate clockwise. The two positioning pins 1102 move inwards and insert into the positioning grooves 901 inside the character mold 9, so that the new character mold 9 is quickly fixed to the positioning box 701.
