[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Referring to Figures 1 to 6 , a label hot stamping and silk screen printing production device and process provided by the present invention will be described below.

[0022] Referring to Figures 1 to 5 , in a first aspect, the present embodiment provides a label hot stamping and silk screen printing production device, including a machine body 1 and an adjustable guide roller device 2 and a parameter adjustment system provided on the machine body 1.

[0023] The adjustable guide roller device 2 is used to provide a label ribbon for hot stamping and printing on the machine body 1. Information identifiers are provided on the label ribbon, and the information identifiers are used to identify the material and thickness information of the label ribbon.

[0024] The parameter adjustment system includes an information reading module fixedly connected to the machine body 1 and an adjustment module communicatively connected to the machine body 1, the information reading module and the adjustable guide roller device 2. The information reading module is used to scan the information identifier so as to read and output the material and thickness information of the label ribbon. After receiving the material and thickness information of the label ribbon, the adjustment module adjusts the roller diameter of the adjustable guide roller device 2 and adjusts parameters such as the temperature and label ribbon tension during the hot stamping and silk screen printing process.

[0025] In a preferred embodiment, the information identifier can be a two-dimensional code pasted on the label ribbon, and the two-dimensional code is used to store the material and thickness information of the label ribbon. The information identifier can be a bar code pasted on the label ribbon, and the bar code is used to store the material and thickness information of the label ribbon. The information identifier is a sticky note pasted on the label ribbon, and there are multiple recognition points on the sticky note, and the recognition points are used to store the material and thickness information of the label ribbon. The information reading module is specifically a scanning gun provided on the machine body 1, and the scanning gun is arranged facing the information identifier. When the information identifier passes by the scanning gun, the scanning gun scans the information identifier, so as to obtain the material and thickness information of the label ribbon stored in the information identifier.

[0026] The barcode scanner is built with a microprocessor. After scanning the information label, the barcode scanner transmits the scanned information to the microprocessor for processing, thereby obtaining the material and thickness information of the label ribbon. The label hot stamping and silk screen printing production equipment provided in this embodiment further includes a database communicatively connected to the adjustment module. The database stores technical parameters such as the temperature required during the hot stamping and silk screen printing processes for various label ribbon materials and thicknesses, the tensile force that the label ribbon can withstand, and the minimum bending radius of the label ribbon. The microprocessor sends the obtained material and thickness information of the label ribbon to the adjustment module. After obtaining the material and thickness information of the label ribbon, the adjustment module retrieves the corresponding technical parameters through the database and then adjusts the technical parameters of the machine body 1.

[0027] Referring to Figure 1 , in a possible implementation, the machine body 1 includes a hot stamping module and a silk screen printing module connected to the hot stamping module. The adjustable guide roller device 2 is used to provide the label ribbon for the hot stamping module and the silk screen printing module, so as to complete the hot stamping and silk screen printing processes.

[0028] The hot stamping module includes a hot stamping plate, a heating device, and a pressure applying device. Among them, the hot stamping plate is usually made of copper plate or zinc plate, and the surface is engraved with patterns or characters to be hot stamped; in the heating device part, elements such as electric heating rods are mostly used to heat the hot stamping plate to the preset working temperature through temperature rise; while the pressure applying device relies on cylinders or hydraulic systems to generate sufficient pressure during operation to ensure that the hot stamping foil is accurately imprinted on the surface of the target material.

[0029] The core structure of the silk screen printing device is the screen plate and ink control. The screen plate is composed of a screen made of polyester or nylon and a metal or wooden frame. The screen mesh number directly affects the printing fineness. The higher the mesh number, the finer the lines. The frame prevents printing deformation through rigid support; the squeegee is made of rubber or polyurethane. Its hardness is suitable for large-area patterns in the hard state and precision printing in the soft state. The angle is usually 45° - 60° and the pressure together determine the ink transfer amount and pattern clarity. The ink supply system includes a sealed container, a delivery pump (pneumatic or electric pump) to accurately control the flow rate, and a stirring device (mechanical or magnetic stirrer) to prevent precipitation, ensuring the uniformity of the ink and the stability of the delivery.

[0030] The drying function is achieved through hot air or ultraviolet light: The hot air dryer accelerates the ink curing by adjusting the temperature and wind speed, improving the adhesion and wear resistance; the ultraviolet drying lamp uses the reaction of photosensitizers to quickly cure UV ink, with the characteristics of high efficiency and energy saving. The two drying methods can be flexibly selected according to the ink type (conventional or UV ink) and the production efficiency requirements to jointly ensure the quality of the printed products.

[0031] In a possible implementation, the adjustment module includes a temperature sensor disposed at the hot stamping module and a controller communicatively connected to both the temperature sensor and the information reading module. The temperature sensor is used to detect and output the temperature information during the hot stamping process in real time. After receiving the temperature information and the material and thickness information of the label ribbon, the controller adjusts the operating temperature of the hot stamping module.

[0032] In a possible implementation, after receiving the temperature information and the material and thickness information of the label ribbon, the controller adjusts the operating temperature of the hot stamping module, including: Obtaining the target temperature when the hot stamping module is operating according to the material and thickness information of the label ribbon; Comparing the temperature information with the target temperature; and Adjusting the temperature when the hot stamping module is operating according to the difference between the temperature information and the target temperature.

[0033] In a preferred embodiment, if the temperature information is lower than the target temperature, calculate the difference between the temperature information and the target temperature. If the difference exceeds the difference threshold, it means that the temperature information is much lower than the target temperature and the temperature of the hot stamping module needs to be adjusted. At this time, the controller controls the hot stamping module to increase the temperature, so that the temperature of the hot stamping module gradually rises to the target temperature, or the difference between the temperature information and the target temperature is lower than the difference threshold. If the difference does not exceed the difference threshold, it means that the difference between the temperature of the hot stamping module and the target temperature is small at this time, and there is no need to adjust the temperature of the hot stamping module.

[0034] If the temperature information is higher than the target temperature, calculate the difference between the temperature information and the target temperature. If the temperature difference exceeds the temperature difference threshold, it means that the temperature information is much higher than the target temperature and the temperature of the hot stamping module needs to be adjusted. At this time, the controller controls the hot stamping module to decrease the temperature, so that the temperature of the hot stamping module gradually decreases to the target temperature, or the temperature difference is lower than the temperature difference threshold. If the temperature difference does not exceed the temperature difference threshold, it means that the difference between the temperature of the hot stamping module and the target temperature is small at this time, and there is no need to adjust the temperature of the hot stamping module.

[0035] In a possible implementation, the adjustment module includes a tension sensor communicatively connected to the controller. The tension sensor is used to detect and output the tension information borne by the label ribbon. The controller receives the tension information and adjusts the tension borne by the label ribbon according to the tension information and the material and thickness information of the label ribbon.

[0036] In a possible implementation, the controller receives the tension information and adjusts the tension borne by the label ribbon according to the tension information and the material and thickness information of the label ribbon, including: Obtaining the target tension according to the material and thickness information of the label ribbon; Comparing the tension information with the target tension; Adjust the tension borne by the label ribbon according to the difference between the tension information and the target tension.

[0037] In a preferred embodiment, during the screen printing process, if the tension information borne by the label ribbon is lower than the target tension, calculate the difference between the tension information and the target tension. If the tension difference exceeds the tension difference threshold, it indicates that there is a large difference between the tension information and the target tension at this time. The controller controls the body 1 to increase the tension borne by the label ribbon during the screen printing process, so as to increase the tension information to the target tension, or reduce the tension difference to within the tension difference threshold range. If the tension difference does not exceed the tension difference threshold, it indicates that the difference between the tension information and the target tension is small, and there is no need to adjust the tension borne by the label screen printing.

[0038] During the screen printing process, if the tension information borne by the label ribbon is higher than the target tension, calculate the difference between the tension information and the target tension. If the tension difference exceeds the tension difference threshold, it indicates that there is a large difference between the tension information and the target tension at this time. The controller controls the body 1 to reduce the tension borne by the label ribbon during the screen printing process, so as to reduce the tension information to the target tension, or reduce the tension difference to within the tension difference threshold range. If the tension difference does not exceed the tension difference threshold, it indicates that the difference between the tension information and the target tension is small, and there is no need to adjust the tension borne by the label screen printing.

[0039] Refer to Figures 2 to 5 , in a possible implementation, the adjustable guide roller device 2 includes a rotating shaft 21 rotatably connected to the body 1 and an adjustment disk mechanism 22 fixedly connected to the rotating shaft 21. A plurality of adjustment disk mechanisms 22 are provided and are evenly distributed along the axial direction of the rotating shaft 21; adjacent adjustment disk mechanisms 22 are arranged in a staggered manner.

[0040] In a possible implementation, the adjustment disk mechanism 22 includes a plurality of adjustment components fixedly connected to the rotating shaft 21. The adjustment components are arranged along the axis of the rotating shaft 21, and the plurality of adjustment components construct a circumferential surface; the adjustment component includes a telescopic member 221 fixedly connected to the circumferential surface of the rotating shaft 21 at one end and a contact block 222 whose inner wall is fixedly connected to one end of the telescopic member 221. The telescopic member 221 is arranged along the radial direction of the rotating shaft 21. The outer side wall of the contact block 222 is an arc surface; the telescopic member 221 is used to adjust the distance between the contact block 222 and the rotating shaft 21.

[0041] When the diameter of the adjustable guide roller device 2 is the smallest, the length of the telescopic member 221 is the shortest, and the adjacent contact members in the same adjusting disc mechanism 22 abut against each other, and the outer side surfaces of the contact members form a complete circumferential surface. When the diameter of the adjustable guide roller device 2 is enlarged, the telescopic member 221 elongates, increasing the distance between the contact member and the rotating shaft 21. At this time, the contact members in the same adjusting disc mechanism 22 are separated from each other, and the distance between them increases. At this time, the contact members in the same adjusting disc mechanism 22 cannot form a complete circumferential surface. Since the adjacent adjusting disc mechanisms 22 are arranged in a staggered manner, the contact members in the adjacent adjusting discs mutually fill the missing circumferences of each other, thereby complementarily forming a relatively complete circumferential surface.

[0042] In order to more clearly show the structure of the adjustable guide roller device 2, the number of contact members in the attached drawings of this embodiment is small. In actual production, the number of contact members in the same adjusting disc mechanism 22 can be increased to 18 or 20 or 25.

[0043] In a preferred embodiment, the contact member is made of rubber with a certain elasticity. When the label ribbon contacts the contact member and applies a certain pressure, the contact member deforms, thereby increasing the contact area between the contact member and the label ribbon, and further enabling each contact member to form a more complete circumferential surface.

[0044] In a preferred embodiment, a rubber layer with a certain elasticity is provided on the outer arc surface of the contact member. When the label ribbon contacts the contact member and applies a certain pressure, the rubber layer deforms, thereby increasing the contact area between the rubber layer and the label ribbon, and further enabling each contact member to form a more complete circumferential surface.

[0045] In a preferred embodiment, an arc-shaped airbag is fixedly connected to the outer arc surface of the contact member. When the pressure inside the airbag increases, the airbag deforms. When the label ribbon contacts the contact member and applies a certain pressure, the airbag deforms. Under the restraint of the label ribbon, the airbag cannot expand radially along the contact member, but can only extend circumferentially along the contact member, thereby increasing the contact area between the label ribbon and the contact member and improving the integrity of the circumferential surface formed by the contact member.

[0046] A label hot stamping and silk printing production device provided by the present invention has the following beneficial effects: Compared with the prior art, when the label hot stamping and silk printing production device of the present invention is working, an identification block is set on the label ribbon to identify information by the identification block. When starting printing, the information reading module scans the identification block, reads the information identification, obtains the material and thickness information of the label ribbon, and adjusts technical parameters such as the temperature during printing and the tension of the label ribbon through the adjustment module. The parameters during printing are automatically adjusted by the parameter adjustment system, reducing the manual working hours during the printing process, reducing the printing difficulty, and improving the printing efficiency.

[0047] Reference Figure 6 Figure 6 , in a second aspect, the present invention provides a production process for hot stamping and silk screening of labels, which is applied to a production device for hot stamping and silk screening of labels as described in the first aspect, and includes the following steps: S1. Obtain the material and thickness information of the label ribbon through an information reading module; S2. Adjust the technical parameters of the hot stamping and silk screening processes according to the material and thickness information of the label ribbon; and S3. Perform hot stamping and silk screening on the label ribbon.

[0048] In a possible implementation, adjusting the technical parameters of the hot stamping and silk screening processes according to the material and thickness information of the label ribbon includes: Adjust the temperature during hot stamping, the tension borne by the label ribbon, and the diameter of the guide roller; the temperature during hot stamping is 100 - 200 °C; the tension borne by the label ribbon is 20 - 30 N / CM.

[0049] If the temperature information is lower than the target temperature, calculate the difference between the temperature information and the target temperature. If the difference exceeds the difference threshold, it means that the temperature information is much lower than the target temperature, and the temperature of the hot stamping module needs to be adjusted. At this time, the controller controls the hot stamping module to increase the temperature, so that the temperature of the hot stamping module gradually rises to the target temperature, or the difference between the temperature information and the target temperature is lower than the difference threshold. If the difference does not exceed the difference threshold, it means that the difference between the temperature of the hot stamping module and the target temperature is small at this time, and there is no need to adjust the temperature of the hot stamping module.

[0050] If the temperature information is higher than the target temperature, calculate the difference between the temperature information and the target temperature. If the temperature difference exceeds the temperature difference threshold, it means that the temperature information is much higher than the target temperature, and the temperature of the hot stamping module needs to be adjusted. At this time, the controller controls the hot stamping module to decrease the temperature, so that the temperature of the hot stamping module gradually decreases to the target temperature, or the temperature difference is lower than the temperature difference threshold. If the temperature difference does not exceed the temperature difference threshold, it means that the difference between the temperature of the hot stamping module and the target temperature is small at this time, and there is no need to adjust the temperature of the hot stamping module.

[0051] If the tension information of the label ribbon is lower than the target tension, calculate the difference between the tension information and the target tension. If the tension difference exceeds the tension difference threshold, it means that the difference between the tension information and the target tension is large at this time. The controller controls the body 1 to increase the tension borne by the label ribbon during silk screening, so that the tension information is increased to the target tension, or the tension difference is reduced to the range of the tension difference threshold. If the tension difference does not exceed the tension difference threshold, it means that the difference between the tension information and the target tension is small, and there is no need to adjust the tension borne by the label silk screening.

[0052] During the silk screen printing process, if the tensile force information borne by the label ribbon is higher than the target tensile force, calculate the difference between the tensile force information and the target tensile force. If the tensile force difference exceeds the tensile force difference threshold, it indicates that there is a significant difference between the current tensile force information and the target tensile force. The controller controls the body 1 to reduce the tensile force borne by the label ribbon during the silk screen printing process, so as to reduce the tensile force information to the target tensile force or reduce the tensile force difference to within the range of the tensile force difference threshold. If the tensile force difference does not exceed the tensile force difference threshold, it indicates that the difference between the tensile force information and the target tensile force is small, and there is no need to adjust the tensile force borne by the label silk screen printing.

[0053] In this process, when the material of the label ribbon is paper, the target temperature range is 100 - 200 °C. When the material of the label ribbon is pure cotton or polyester cotton, the target temperature range is 140 - 160 °C. When the material of the label ribbon is silk or acrylic, the target temperature range is 100 - 200 °C.

[0054] A label hot stamping and silk screen printing production process provided by the present invention has the following beneficial effects: Compared with the prior art, in the label hot stamping and silk screen printing production process of the present invention, identification blocks are provided on the label ribbon to identify information by using the identification blocks. At the start of printing, the information reading module scans the identification blocks to read the information identification, obtains the material and thickness information of the label ribbon, and adjusts technical parameters such as the temperature during printing, the tensile force of the label ribbon, and the diameter of the guide roller through the adjustment module. The parameters during printing are automatically adjusted by the parameter adjustment system, reducing the manual working hours during the printing process, reducing the printing difficulty, and improving the printing efficiency.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
