[0001] This utility model relates to the field of trademark printing machine technology, specifically a cutting mechanism for a trademark printing machine. Background Technology

[0002] Label printing machines, also known as self-adhesive printing machines, are equipment used to print labels and trademarks. Label printing and label equipment manufacturing have absorbed the strengths of various printing technologies, gradually forming a relatively independent system to adapt to the diversified development of label applications. The cutting mechanism of a label printing machine is a device that cuts the labels to the required specifications after printing.

[0003] Existing trademark printing machine cutting mechanisms may cause wrinkles on the trademark during cutting, affecting cutting accuracy. Furthermore, the trademark is prone to loosening during cutting, which affects the cutting quality of the cutting blade. Therefore, we propose a new trademark printing machine cutting mechanism.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1:

[0026] A preferred embodiment of the trademark printing machine cutting mechanism provided by this utility model is, for example... Figures 1 to 6 As shown: A cutting mechanism for a trademark printing machine includes a cutting table 1, a bracket 2 fixedly installed at the top of the cutting table 1, a support leg 17 fixedly installed at the bottom of the cutting table 1, an electric cylinder 3 fixedly installed at the top of the bracket 2, a fixed plate 4 fixedly installed at the output end of the electric cylinder 3, a cutting blade 5 fixedly installed at the bottom of the fixed plate 4, and smoothing and straightening mechanisms 6 provided on both sides of the cutting blade 5.

[0027] The smoothing and straightening mechanism 6 includes a fixed base 601, a folding plate 602, and a smoothing roller 606. The fixed base 601 is fixedly installed at the bottom end of the fixed plate 4. A connecting shaft 603 is fixedly installed on the inner wall of the fixed base 601. A shaft hole 605 is opened at the top end of the folding plate 602. The connecting shaft 603 movably passes through the shaft hole 605. A torsion spring 604 is fixedly connected between the inner wall of the shaft hole 605 and the outer wall of the connecting shaft 603. A rotating groove 607 is opened at the bottom end of the folding plate 602. A rotating shaft 608 is rotatably connected to the inner wall of the rotating groove 607 through a bearing. One end of the rotating shaft 608 passes through the front of the folding plate 602. The smoothing roller 606 is fixedly sleeved on the outer wall of the rotating shaft 608. A ratchet assembly is provided between one end of the rotating shaft 608 and the fixed base 601.

[0028] Specifically, in the above technical solution, when the cutting mechanism of the trademark printing machine is in use, the electric cylinder 3 is activated, causing the electric cylinder 3 to move the fixed plate 4 downwards, which in turn moves the cutting blade 5 downwards. The fixed plate 4 also moves the folding plate 602 downwards via the fixed seat 601. Before the cutting blade 5 contacts the trademark, the folding plate 602 moves the smoothing roller 606 to contact the trademark, causing the two smoothing rollers 606 to roll on both sides of the trademark, smoothing out the wrinkles on the trademark. When the cutting blade 5 cuts the trademark, the rotating shaft 608 will be at the ratchet 609. The component cannot rotate, preventing the smoothing roller 606 from rotating in the opposite direction during trademark cutting. This allows the smoothing roller 606 to straighten the trademark during cutting, ensuring cutting quality. Through this structure, the cutting blade 5 can smooth and straighten the trademark in advance during cutting, greatly improving the cutting quality. This solves the problem that existing trademark printing machine cutting mechanisms may have wrinkles on the trademark that affect cutting accuracy, and the trademark may become loose during cutting, thus affecting the cutting quality of the cutting blade 5.

[0029] Furthermore, the ratchet assembly includes a ratchet 609 and a pawl 611. The ratchet 609 is fixedly installed at one end of the rotating shaft 608. A connecting shaft 612 is fixedly installed on the front of the fixing seat 601. A shaft hole 613 is opened at one end of the pawl 611. The connecting shaft 612 moves through the shaft hole 613. A torsion spring 614 is fixedly connected between the outer wall of the connecting shaft 612 and the inner wall of the shaft hole 613. The pawl 611 is configured to cooperate with the ratchet 609.

[0030] By setting a pawl 611, the pawl 611 can limit the ratchet 609, so that the ratchet 609 can only rotate in one direction.

[0031] Furthermore, a baffle 610 is fixedly installed at one end of the second coupling 612;

[0032] By setting the baffle 610, the pawl 611 can be limited, thereby improving the stability of the pawl 611 during use.

[0033] Furthermore, a limiting slide plate 8 is fixedly installed on the back of the fixing plate 4, and a limiting groove 7 is opened on the inner side of the bracket 2, and the limiting slide plate 8 is slidably connected to the limiting groove 7;

[0034] By setting the limiting slide plate 8 and the limiting slide groove 7, the fixing plate 4 can be limited to ensure the stability of the fixing plate 4 during use.

[0035] Example 2:

[0036] Based on Embodiment 1, a preferred embodiment of the trademark printing machine cutting mechanism provided by this utility model is, for example... Figures 1 to 6As shown: The cutting table 1 has a cavity 13 inside. A vacuum pump 15 is fixedly installed at the bottom of the cutting table 1. A vacuum tube 14 is connected to the output end of the vacuum pump 15. The vacuum tube 14 passes through the bottom end of the cutting table 1 and is connected to the cavity 13. An adsorption hole 16 is connected between the top end of the cutting table 1 and the cavity 13. A fixing block 9 is slidably connected to the inner wall of the limiting slide groove 7 near the bottom end. A contact switch 10 is fixedly installed at the top end of the fixing block 9. The contact switch 10 is electrically connected to the vacuum pump 15. A spring 12 is fixedly connected between the bottom end of the fixing block 9 and the bottom end of the inner wall of the limiting slide groove 7.

[0037] Specifically, in the above technical solution, when the fixed plate 4 moves downward, it will drive the limiting slide plate 8 to move downward. When the limiting slide plate 8 contacts the contact switch 10, the vacuum pump 15 is energized and started, so that the vacuum pump 15 draws a vacuum into the cavity 13 through the vacuum tube 14, which can make the trademark firmly adsorbed onto the cutting table 1 through the adsorption hole 16, thereby further improving the stability of the trademark during cutting and greatly improving the cutting quality. The structure is simple and highly practical. Meanwhile, the fixed block 9 will squeeze the spring 12 to move downward continuously, ensuring the normal movement of the fixed plate 4.

[0038] Furthermore, a limiting rod 11 is fixedly installed at the bottom of the fixing block 9. The limiting rod 11 is inserted into the rod groove opened at the bottom of the inner wall of the limiting slide groove 7, and the spring 12 surrounds the outer wall of the limiting rod 11.

[0039] The limiting rod 11 can limit the movement of the spring 12 and the fixing block 9, ensuring the stability of the fixing block 9 and the spring 12 during compression.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
