Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment technology, and in particular to an improved hot stamping equipment for processing self-adhesive labels. Background Technology

[0002] Self-adhesive labels are widely used in food packaging, logistics labeling, electronic components and other fields due to their convenient application and strong adaptability. Their surface hot stamping process can enhance the aesthetics and anti-counterfeiting performance of the labels, becoming a key link in high-end label processing.

[0003] In the hot stamping process, the surface of the label tape is heated and pressurized to transfer metallic foil material to designated graphic areas, thus forming a decorative and anti-counterfeiting metallic pattern. If the tension is not adjusted or the tape is not rewound promptly after hot stamping, problems such as wrinkling of the hot stamping film, tape breakage, and positioning misalignment can easily occur. Therefore, to ensure the quality of the finished product, the hot-stamped self-adhesive label tape usually needs to be rewound by a rewinding mechanism.

[0004] However, the winding drum mounting mechanism in traditional winding mechanisms is mostly designed with a fixed diameter. When processing self-adhesive labels of different specifications, it is necessary to replace the mounting shaft of the corresponding size. The replacement process takes 15-20 minutes per time, and frequent replacement can easily lead to wear of the mechanism and affect the installation stability. Therefore, an improved hot stamping device for self-adhesive label processing is proposed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an improved hot stamping device for self-adhesive label processing.

[0006] This utility model is achieved through the following technical solution: An improved hot stamping device for self-adhesive label processing includes a machine body. A web guiding module is located on the upper left surface of the machine body. Two printing modules are located on the left side surface of the machine body. A drying module is located near the center of the right side of the machine body. A hot stamping module is located at the upper end of the rear end of the machine body. A secondary printing module is located on the upper surface of the rear end of the machine body. A control panel is also located on the surface of the rear end of the machine body. A variable diameter mounting mechanism is located on the inner sidewall of the front end of the machine body. The variable diameter mounting mechanism is used for adjusting the installation according to self-adhesive reel rolls of different diameters. The printing module, hot stamping module, and drying module are used to hot stamp the surface of the self-adhesive label and then dry it.

[0007] As a further description of the above technical solution: the variable diameter installation mechanism includes a fixed plate, a connecting shaft is fixedly connected to the center of the surface of the fixed plate, and a bidirectional threaded rod is rotatably connected to the inner sidewall of the connecting shaft.

[0008] As a further description of the above technical solution: a guide groove is provided on the surface of the connecting shaft, and a sliding ring is slidably connected to the inner wall of the guide groove of the connecting shaft.

[0009] As a further description of the above technical solution: the sliding ring protrusion is threadedly connected to the surface of the bidirectional threaded rod.

[0010] As a further description of the above technical solution: the surface of the bidirectional threaded rod is provided with two sets of threads with opposite directions of rotation, the arc surface of the sliding ring is provided with a protrusion, and the protrusion of the sliding ring is provided with an internal thread groove.

[0011] As a further description of the above technical solution: a rotating block is rotatably connected to the end surface of the connecting shaft away from the fixed disk, and the rotating block is fixedly connected to the rotation center point of the bidirectional threaded rod.

[0012] As a further description of the above technical solution: the outer arc surfaces of both sets of sliding rings are hinged with three sets of hinge rods, and the ends of the three sets of hinge rods away from the sliding rings are hinged with arc-shaped plates.

[0013] As a further description of the above technical solution: the rear ends of the three sets of arc-shaped plates are in contact with the inner surface of the fixed disk.

[0014] This utility model has the following beneficial effects: In this invention, the rotating block drives the bidirectional threaded rod to rotate, and the two sets of sliding rings move in opposite directions along the guide groove of the connecting shaft. Through the hinge rod, the three sets of arc plates are pushed to expand or contract synchronously, which can be adapted to self-adhesive take-up drums with different inner diameters. The adjustment range covers the existing mainstream specifications. The rubber anti-slip layer on the outer surface of the arc plate increases the friction coefficient and ensures that the take-up drum is installed without swaying.

[0015] At the same time, the correction module adjusts the film material feeding position in real time, the hot stamping module and the drying module are closely connected, and the drying process can begin within 1 second after hot stamping. The secondary printing module and the primary printing module meet the fine requirements of multi-color overprinting. Attached Figure Description

[0021] Reference Figure 1 - Figure 3 An embodiment of this utility model provides an improved hot stamping device for processing self-adhesive labels, comprising a body 1, a correction module 2 provided on the upper left side surface of the body 1, which can correct and transport the self-adhesive film mounted on the surface of the variable diameter mounting mechanism 8 by providing the correction module 2, two sets of printing modules 3 provided on the left side surface of the body 1, a drying module 5 provided near the center on the right side of the body 1, a hot stamping module 4 provided at the upper end of the rear end of the body 1, a secondary printing module 6 provided on the upper surface of the rear end of the body 1, a control panel 7 provided on the surface of the rear end of the body 1, and a variable diameter mounting mechanism 8 provided on the inner side wall of the front end of the body 1. The variable diameter installation mechanism 8 is used to adjust the installation according to the different diameters of self-adhesive reel rolls. By setting the variable diameter installation mechanism 8, two layers of self-adhesive film can be installed on its surface, and a tear-off layer is set on its surface. By opening the tear-off layer, the base material is exposed.

[0022] The functions of printing module 3, hot stamping module 4, and drying module 5 are to hot stamp the surface of the self-adhesive film and then dry it. The printing module 3 allows the self-adhesive film to be printed and hot stamped after being peeled off, and then conveyed to the drying module 5 for drying. The hot stamping module 4 is equipped with two sets of rollers, one for waste material winding and the other for hot stamping material mounting, and it is printed a second time after passing through the secondary printing module 6.

[0023] Reference Figure 2 - Figure 4 The variable diameter mounting mechanism 8 includes a fixed disk 81, with a connecting shaft 82 fixedly connected to the center of the surface of the fixed disk 81. The fixed disk 81 is used to attach and install the self-adhesive label roll. A guide groove is formed on the surface of the connecting shaft 82, and a sliding ring 85 is slidably connected to the inner wall of the guide groove. Two sets of threads with opposite directions are formed on the surface of the bidirectional threaded rod 84. A protrusion is provided on the arc surface of the sliding ring 85, and an internal thread groove is formed at the protrusion of the sliding ring 85. By providing the bidirectional threaded rod 84, when it rotates, the protrusions at the bottom of the two sets of sliding rings 85 move closer together on the inner wall of the guide groove of the connecting shaft 82, and simultaneously move towards or away from each other on the surface of the bidirectional threaded rod 84. The protrusion portion of the sliding ring 85 is threadedly connected to the surface of the bidirectional threaded rod 84. The connecting shaft 82... A bidirectional threaded rod 84 is rotatably connected to the inner side wall. A rotating block 83 is rotatably connected to the end surface of the connecting shaft 82 away from the fixed disk 81. The rotating block 83 is fixedly connected to the rotation center point of the bidirectional threaded rod 84. Three sets of hinge rods 86 are hinged to the outer arc surfaces of the two sets of sliding rings 85. An arc plate 87 is hinged to the end of the three sets of hinge rods 86 away from the sliding rings 85. The rear ends of the three sets of arc plates 87 are in contact with the inner surface of the fixed disk 81. When the two sets of sliding rings 85 move closer or further apart, they will push the arc plate 87 outward through the hinge rods 86, so as to install the self-adhesive label tube according to the inner diameter. At the same time, a rubber anti-slip layer is provided on the outer surface of the arc plate 87, which can increase the contact friction with the self-adhesive label tube and make it stable to be installed on the surface of the arc plate 87.

[0024] Working principle: First, the adaptive installation of the self-adhesive take-up cylinder and the preparation of film material are completed through the variable diameter installation mechanism 8: The variable diameter installation mechanism 8 on the inner side of the front end of the machine body 1 is based on the fixed plate 81, and the connecting shaft 82 at the center of the fixed plate 81 is used to support the self-adhesive take-up cylinder; according to the inner diameter of the self-adhesive take-up cylinder, the rotating block 83 at the end of the connecting shaft 82 is rotated, and the rotating block 83 drives the fixed bidirectional threaded rod 84 to rotate synchronously; the two sets of threads with opposite directions on the surface of the bidirectional threaded rod 84 drive the two sets of sliding rings 85 to move closer or further apart; the sliding rings 85 push the arc plate 87 to expand outward or contract inward through the three sets of hinge rods 86 hinged to the outer arc surface until the rubber anti-slip layer on the outer surface of the arc plate 87 is in close contact with the inner wall of the self-adhesive take-up cylinder, thus completing the fixed installation of the take-up cylinder; then, two layers of self-adhesive film are installed on the surface of the variable diameter installation mechanism 8, and the peel-off layer is peeled off to expose the substrate, preparing for subsequent processing.

[0025] Next, the printing, hot stamping, and drying of the self-adhesive labels are completed through multi-module collaboration: After the equipment is started, the self-adhesive film is output from the variable diameter mounting mechanism 8, and first passes through the correction module 2 on the left side of the machine body 1. The correction module 2 adjusts the film material feeding position to avoid deviation; then the film material passes through two sets of printing modules 3 in sequence, and the printing modules 3 perform preliminary printing on the film material base; the printed film material is conveyed to the hot stamping module 4 at the rear of the machine body 1, and the hot stamping module 4 performs hot stamping on the surface of the film material through two sets of rollers; the hot stamped film material enters the drying module 5, and the drying module 5 dries and cures the hot stamping layer to prevent it from falling off; the dried film material continues to be conveyed to the secondary printing module 6 for secondary printing to complete the label pattern or information; throughout the entire processing, the operator can adjust the parameters of each module through the control panel 7 to ensure the processing quality, and finally complete the preparation of the improved hot stamping self-adhesive label.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
