Description

Technical Field

[0001] The utility model relates to the field of insulating hot embossing printing, and more specifically, to a long-distance insulating hot embossing printing device. Background Art

[0002] In order to distinguish the manufacturer's name, product model, rated voltage and other continuous marks, cable products are often marked on the cable surface by ink printing wheels, inkjet printer printing, printing wheel hot embossing and other methods.

[0003] For overhead insulated conductors exported to Africa or South America, customers often require hot stamping for the printed characters on the finished cable sheaths, with high requirements for the printed characters. Conventional hot stamping devices are currently designed based on the lever principle and are typically fixed to the extruder head in a simple manner. The diameter of the printing wheel is typically between 100mm and 300mm. This design does not fully consider many key factors, such as the maximum length of the meter mark distance, the size of the printing wheel, the fixing position, the pressure applied by the printing wheel on the cable surface, and the potential impact of the extruded material's cooling and shrinkage process and long-term natural rebound on the printing quality. Some of the export orders require that one mark be stamped per meter. The traditional small-size stamping wheel device can no longer meet the long-distance stamping requirements. When two marks are stamped on a 1-meter product or three marks are stamped on a 1-meter product, the traditional small stamping wheel is used to stamp the text on the cable surface. The font is clear and complete, and the sheath on the cable surface with the font printed will not become thinner. However, when the stamping mark requires one mark to be stamped per meter, the cable is in a state of rotation during the production process, and the cable swings greatly during the production process. When a large-diameter stamping wheel is used to stamp on the insulation or sheath surface, uneven stamping such as shallow stamping or missing stamping often occurs. At the same time, the weight of the stamping wheel may affect the line angle, resulting in scraping. Utility Model Content

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0020] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] like Figure 1-3 As shown, a technical solution of the present invention provides a long-distance insulated hot embossing printing device, comprising: a hot embossing wheel 1, a compressible spring device 2, a bracket 3 and a cable 8;

[0024] The hot stamping wheel 1 is vertically arranged between two brackets 3 through a horizontally arranged wheel axle. The compressible spring device 2 is arranged on the top of each bracket. The two ends of the wheel axle are respectively arranged on the compressible spring device 2. The cable 8 is horizontally arranged and passes through the wheel groove at the bottom end of the hot stamping wheel 1 to be printed by the hot stamping wheel 1.

[0025] The hot stamping wheel 1 is mainly used for printing on the surface of the cable 8. Its working principle is to use the circumference as the unit period to stamp the embossed characters engraved on the stamping wheel 1 onto the surface of the cable 8 by hot pressing. Because traditional hot stamping devices cannot effectively control the pressure of the stamping wheel on the cable, excessive pressure will over-squeeze the cable, causing the sheath on the cable surface to become thinner or affecting the wire angle and causing scraping; too little pressure will result in unclear printing or even no printing. In the above technical solution, the compressible spring devices 2 on both sides can increase the stability of the hot stamping wheel fixing device to avoid uneven stamping marks; and the pressure applied by the stamping wheel on the cable surface can be flexibly adjusted according to actual production needs.

[0026] In another technical solution, the bracket 3 is a height-adjustable bracket, so that the height can be adjusted according to actual conditions.

[0027] By cooperating with the hot embossing wheel 1 and the compressible spring devices 2 on both sides, the degree of downward pressure of the hot embossing wheel 1 can be steplessly adjusted, and a set of brackets are provided on each side of the hot embossing wheel 1, and a compressible spring device 2 is provided on the bracket. After the bracket 3 is adjusted to an appropriate height according to actual production conditions, it is fixed, and then the compressible spring devices 2 on both sides are adjusted separately to more flexibly adjust the hot embossing wheel 1 to the optimal position.

[0028] In another technical solution, the long-distance insulated hot embossing printing device also includes an extruder head 7 and an extruder water tank 10, which are respectively located at the front and rear ends of the hot embossing wheel 1 along the cable travel direction. The wire 9 passes through the extruder head 7 to form a cable 8, and the cable 8 enters the extruder water tank 10.

[0029] In the above technical solution, after the wire 9 passes through the extruder head 7, its surface will be wrapped with a layer of plastic to form a cable 8. At this time, the temperature of the cable 8 is very high. After entering the extruder water tank 10, the extruder water tank 10 can quickly cool the cable.

[0030] In another technical solution, the long-distance insulating hot embossing printing device further includes:

[0031] The wire feed stabilizer is located at the front end of the extruder head 7 and limits the wire 9.

[0032] In the above technical solution, by adding a wire feed stabilizer, the wire is positioned before the conductor enters the extruder head, thereby reducing the swing amplitude of the wire;

[0033] Another technical solution provides a specific structure of a wire feed stabilizer, which includes two vertical limiting wheels 5 and two horizontal limiting wheels 6. The two vertical limiting wheels 5 are arranged vertically and parallel to each other, and the two horizontal limiting wheels 6 are arranged horizontally and parallel to each other, forming a horizontal channel between the four wheels for the wire 9 to pass through. The two vertical limiting wheels 5 and the two horizontal limiting wheels 6 are staggered in the horizontal and vertical directions to avoid mutual interference.

[0034] In another technical solution, the bracket 3 includes two brackets that are nested within each other. Each bracket has a plurality of through holes. Through holes at different locations on the two brackets are selected and aligned, and the butterfly turnbuckles 4 are then inserted into the aligned through holes. After the bracket 3 is adjusted to a suitable height based on actual production conditions, the butterfly turnbuckles 4 are used to secure it.

[0035] In another technical solution, a base is provided at the bottom of the bracket, and the base is relatively heavy, making the entire structure more stable.

[0036] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
