Description

Technical Field

[0001] The utility model belongs to the technical field of hot stamping, and in particular relates to a marking machine for PVC film processing. Background Art

[0002] Hot stamping machine is a commonly used processing equipment. It can print patterns, text and other information onto PVC film through heat pressing. This marking method has the advantages of easy operation, clear printing effect and good durability. Therefore, it is widely used in the field of PVC film marking and processing.

[0003] The patent with publication number CN209813447U in the prior art discloses a new type of marking machine for PVC film processing, which includes a device body, a storage cavity, a hinged base, a vertical plate and a film-bearing roller. A vertical plate is installed on one side of the top of the device body, and a control panel is installed at the center position of the top of the vertical plate. A cylinder is fixed on the side wall of the vertical plate below the control panel. Since the working pressure of the cylinder depends on the supply of compressed air, and the pressure of the compressed air may fluctuate due to various factors, such as the working state of the air compressor and the pressure loss in the pipeline, it may directly affect the output pressure of the cylinder, resulting in this driving method may have the defect of poor pressure regulation accuracy. When processing PVC films of different thicknesses, poor adjustment accuracy may make it difficult for the hot stamping machine to accurately control the force when applying pressure, resulting in different depths of marks on the PVC film. Thinner PVC films may rupture due to excessive pressure, while thicker films may be unclearly marked due to insufficient pressure. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example

[0025] Reference Figures 1 to 4 , is an embodiment of the present invention, which provides a marking machine for PVC film processing, which can achieve precise adjustment of the pressure of the hot stamping machine to ensure that the marking effect remains consistent when processing PVC films of various thicknesses.

[0026] The supporting mechanism 100 includes a supporting frame 101 and a supporting platform 102 disposed on the outer surface of the supporting frame 101;

[0027] It should be noted that the support platform 102 is used to support the PVC film. The support platform 102 is made of aluminum alloy, which has high strength and hardness and can withstand large pressures and temperature fluctuations. At the same time, the aluminum alloy also has good thermal conductivity, which helps to evenly distribute heat.

[0028] The hot pressing mechanism 200 includes a motor 201 adapted to be installed on the inner side of the support frame 101, a connecting shaft 202 fixedly connected to the output end of the motor 201, a turntable 203 fixedly sleeved on the through end of the connecting shaft 202, a stamping assembly 204 arranged on the outer surface of the turntable 203, and a fixing assembly 205 arranged on the outside of the stamping assembly 204.

[0029] Specifically, the stamping assembly 204 includes a limit frame 204a fixedly connected to the outer surface of the turntable 203, a knob 204b arranged outside the limit frame 204a, a threaded rod 204c fixedly sleeved on the through end of the knob 204b, and an internal thread block 204d threadedly connected to the outer surface of the threaded rod 204c.

[0030] Furthermore, the outer surface of the knob 204b is in rotational contact with the inner surface of the limit frame 204a, the other end of the threaded rod 204c is fixedly mounted on the inner wall of the limit frame 204a through a bearing, and the outer surface of the internal thread block 204d is in sliding contact with the inner wall of the limit frame 204a.

[0031] Preferably, the stamping assembly 204 also includes a hinged rod 204e hinged to the outer surface of the internal thread block 204d, a hot stamping machine 204f hinged to the other end of the hinged rod 204e, a guide rail 204g fixedly connected to both sides of the outer surface of the support frame 101 and used in conjunction with the hot stamping machine 204f, and a limit plate 204h fixedly connected to the top of the guide rail 204g.

[0032] It should be noted that when the turntable 203 rotates, it can drive the hot stamping machine 204f to perform a straight line reciprocating motion up and down to perform hot stamping on the PVC film. When the internal thread block 204d performs a straight line motion, it can drive the hinged rod 204e and the stamping machine 204f to move synchronously, thereby adjusting the reciprocating motion stroke of the stamping machine 204f to accurately control the contact pressure between the hot stamping machine 204f and the PVC film, ensuring that the marking effect remains consistent when processing PVC films of various thicknesses. The reciprocating motion stroke of the stamping machine 204f after adjustment can be fixed by the fixing component 205, thereby significantly improving the accuracy and consistency of marking.

[0033] It should be noted that the inner surface of the hot stamping machine 204 f is in sliding contact with the outer surface of the guide rail 204 g , and the outer end surface of the limiting plate 204 h is fixedly connected to the outer surface of the support frame 101 .

[0034] Furthermore, the fixing assembly 205 includes a connecting block 205a fixedly connected to the outside of the limit frame 204a, a fixing block 205b fixedly connected to the outer surface of the connecting block 205a, a plug-in column 205c slidingly contacting the inner surface of the fixing block 205b, and a connecting column 205d fixedly connected to the inner surface of the plug-in column 205c.

[0035] Specifically, the fixing assembly 205 also includes a spring 205e sleeved on the outer surface of the connecting column 205d, a limit block 205f fixedly connected to the other end of the connecting column 205d, a limit plate 205g fixedly connected to the outer surface of the connecting block 205a and used in conjunction with the spring 205e, and a plug-in slot 205h distributed in a circular array on the surface of the knob 204b and used in conjunction with the plug-in column 205c. The outer surface of the connecting column 205d is in sliding contact with the surface of the limit plate 205g, the other end of the spring 205e is fixedly connected to the outer surface of the limit plate 205g, and the outer surface of the plug-in column 205c is in sliding contact with the inner wall of the plug-in slot 205h.

[0036] It should be noted that when the plug-in column 205c is inserted into the plug-in slot 205h, it can limit the knob 204b to prevent the knob 204b from rotating due to external force or vibration, thereby causing the reciprocating motion stroke of the hot stamping machine 204f to change.

[0037] During use, the motor 201 is turned on to drive the connecting shaft 202 and the rotating disk 203 to rotate synchronously. The rotating disk 203 cooperates with the limiting frame 204a, which drives the threaded rod 204c and the internal threaded block 204d to move synchronously. The threaded rod 204c cooperates with the hinged rod 204e, which drives the outer surface of the guide rail 204g of the hot stamping machine 204f to reciprocate up and down, so that the hot stamping machine 204f performs hot stamping on the PVC film on the top of the support platform 102.

[0038] After replacing the PVC film with a different thickness, pull the limit block 205f, and through the cooperation between the limit block 205f and the connecting column 205d, drive the plug-in column 205c to move to the outside of the plug-in slot 205h, so as to release the limit of the knob 204b, and make the plug-in slot 205h squeeze the spring 205e, turn the knob 204b to drive the threaded rod 204c to rotate, and through the limit frame 204a to limit the internal thread block 204d, the internal thread block 204d drives the hinged rod 204e and the heat exchanger 205h to rotate. The stamping machine 204f moves synchronously to adjust the reciprocating motion stroke of the hot stamping machine 204f to adapt to various PVC films of different thicknesses. After the adjustment is completed, the limit block 205f is released, and the plug-in column 205c is reset by the reaction force of the spring 205e, so that the plug-in column 205c is inserted into the plug-in slot 205h again, and the knob 204b is limited to prevent the knob 204b from rotating due to external force or vibration, thereby causing the reciprocating motion stroke of the hot stamping machine 204f to change.

[0039] In summary, the stamping component 204 is used to precisely adjust the pressure of the hot stamping machine 204f, and the locking mechanism of the fixing component 205 is used to prevent the pressure of the hot stamping machine 204f from changing due to external force or vibration. This significantly improves the marking consistency when facing PVC films of different thicknesses, while ensuring the stability and reliability of the pressure of the hot stamping machine 204f, so that the equipment can adapt to the processing of PVC films of various thicknesses and improve product quality.
