Description

Technical Field

[0001] The present invention relates to the technical field of label production, and more specifically, to a label printing device with automatic feeding and its use method. Background Art

[0002] Labels were initially used for product identification of medicines and fabrics. With the development of society, their application scope has gradually expanded to fields such as sociology, printing industry, information technology, etc. In the printing industry, labels mainly refer to printed products with adhesive backing, such as common self-adhesive labels. Label printing devices are the core tools for label production, and their development is closely related to the expansion of label application scenarios and the iteration of printing technologies.

[0003] However, in traditional label printing devices, printing and gluing are often two independent and sequential processes. After printing is completed, the device needs to pause and wait for the gluing device to be in place and start working. During this period, the device is idling, which not only wastes a lot of time but also increases energy consumption. In view of this, we propose a label printing device with automatic feeding and its use method. Summary of the Invention

[0019] The drying air box is installed on the frame, and the drying air box is located at the bottom end of the carrier. The drying fan is installed inside the drying air box.

[0024] Preferably, the protection frame body includes a drying frame and a heat insulation frame;

When the protection frame body forms a drying chamber, the two heat insulation frames and the drying frame are respectively located above the two glue coating parts and the printing parts. Guide wind plates and air guiding convex blocks are installed on both inner sides of the drying frame. The two air guiding convex blocks are located between the two guide wind plates.

A number of flow guiding plates are equidistantly installed on the air guiding convex blocks, and the flow guiding plates extend along the surface of the air guiding convex blocks in the other drying air duct. An air outlet groove is opened at the top end of the drying frame, and the air outlet groove is communicated with the air extraction plate.

[0026] A using method of a fully automatic feeding label printing device includes the following steps:

[0027] S1. Raw material transportation: The carrier and the protective film are respectively placed on the transportation parts at the lower and upper parts of the feeding structure. The feeding structure transports the carrier and the protective film through the printing structure, the glue coating structure, the drying structure, and the glue protection structure;

[0028] S2. Glue application and printing: When the carrier passes through the printing structure and the glue application structure, the printing structure and the glue application structure work synchronously to print the carrier and apply glue to the front end and the rear end of the printing part;

[0029] S3. Drying and protection: After the carrier is printed and glued, it continues to move forward. A drying frame of the glue protection structure moves cyclically through the track structure to cover the printing part, and two heat insulation frames move to the two glue application parts. The printing part is dried by the cooperation of the drying frame and the drying structure. At the same time, the heat insulation frames isolate the glue application parts outside the drying structure to prevent the glue from being dried;

[0030] S4. Rolling and pressing forming: After the drying operation, the glued carrier and the protective film are conveyed to the rolling and pressing part through the feeding structure, and the label is rolled and formed.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. Through the linkage design of the printing and glue application structures, the present invention enables the glue application part and the printing part to move synchronously in the vertical direction. The glue gun applies glue precisely at the edge of the label, seamlessly connecting with the printing action, reducing the idle time of the equipment. At the same time, during the subsequent drying process, the glue is not affected by drying and prematurely cured through the continuously moving glue protection structure. By setting the printing and glue application processes to be synchronous and protecting the glue during the drying process through the glue protection structure, the present invention saves the time waiting for the glue application equipment to work and improves work efficiency.

[0033] 2. Through the wavy round rod-shaped guide rod and the telescopic rod, since the guide rod is wavy, the mounting block will make a reciprocating motion along the wavy track through the telescopic rod during the movement. The glue gun is mounted on the mounting block, so the glue gun will also move along a wavy path accordingly. When applying glue to a label with a wavy shape, the movement path of the glue gun can be made to match the wavy edge of the label. For labels with different wavy shapes and different sizes, only by changing the shape of the guide rod or adjusting the driving mode of the second linear driving device, the adjustment of the glue application path can be easily achieved. The design of the wavy round rod-shaped guide rod and the telescopic rod of the present invention provides a more flexible and precise solution for label glue application operations, and can effectively improve the glue application quality and production efficiency of labels.

[0034] 3. Through the collaborative design of the drying structure and the stopping structure, the present invention realizes efficient drying and precise positioning control after label printing. The drying air box is internally provided with a drying fan to generate a directional air flow. The arc surfaces of the two side air guiding arc blocks are attached to the bottom surface of the carrier to form a closed air duct, enabling the hot air to act uniformly on the printing area. The stopper in the stopping structure is connected to the accommodating block through an elastic member. When the movement of the carrier triggers the piezoelectric inductor, the system immediately controls the winding and pressing roller to pause, allowing the label to stay above the drying air box for a specified time. The design of the present invention breaks through the problem of turbulent air flow in the traditional drying method, ensures the rapid curing of printing ink in a controllable environment, and at the same time precisely controls the drying residence time of the label, reducing the rejection rate caused by insufficient drying.

[0035] 4. The rail trolley of the glue protection structure of the present invention slides on the loop-shaped walking track, enabling the protection frame body to move cyclically above the drying air box. The auxiliary slide bar slides on the auxiliary slide bar with the same structure as the walking track structure to provide auxiliary support for the movement of the protection frame body. When the protection frame body moves above the drying air box, it can cooperate with the drying air box to form a protection space, preventing the glue from curing prematurely due to the influence of drying, ensuring the label printing quality, and improving the production efficiency. The present invention can form a protection space by the cooperation of the protection frame body and the drying air box, prevent the glue from curing prematurely due to the influence of drying, ensure the label printing quality, and improve the production efficiency.

[0036] 5. Through the uniquely designed protection frame body, the present invention further optimizes the glue protection and drying effects. The protection frame body is composed of a drying frame and two side heat insulation frames. When forming a drying chamber, it can accurately cover the glue application part and the printing part. The air guiding plate and the air guiding convex block in the drying frame form a drying air duct, and the two side air ducts communicate at the carrier, ensuring smooth air flow. The diversion plate on the air guiding convex block guides the air flow, enabling the hot air to act uniformly on the printing area. The air outlet slot at the top of the drying frame is connected to the air extraction plate to timely discharge moisture and heat. The present invention can prevent the glue from curing prematurely, efficiently dry the printed content, improve the label printing quality and production efficiency, and provide a reliable guarantee for label printing.

[0056] The gluing structure 4 is installed on the printing structure 3. The two gluing parts of the gluing structure 4 are respectively equidistantly located on both sides of the printing structure 3. The gluing structure 4 and the printing structure 3 move synchronously in the vertical direction, and the gluing part of the feeding structure 2 and the printing part of the printing structure 3 work simultaneously; the printing structure 3 includes a printing device 301 and a first linear driving device 302; the printing device 301 is installed at the output end of the first linear driving device 302, and the first linear driving device 302 is installed on the frame 1; the gluing structure 4 includes a second linear driving device 401, a mounting block 402, and a dispensing gun 403; the two second linear driving devices 401 are respectively installed on both sides of the printing device 301, the output end of the second linear driving device 401 drives the mounting block 402 to move, and the dispensing gun 403 is installed on the mounting block 402.

[0057] The drying structure 5 includes a drying air box 501, the drying air box 501 is attached to the bottom end of the carrier, and a drying fan 502 is provided inside the drying air box 501.

[0058] The glue protection structure 6 includes a number of protection frames 601. The number of protection frames 601 moves cyclically along the track structure at equal intervals, and the protection frame 601 moving above the drying air box 501 communicates with the drying air box 501 to form a drying chamber. The drying chamber wraps the printing part passing through the carrier inside, and separates the gluing part passing through the carrier outside. The cycle of each protection frame 601 switching to the drying air box 501 is the same as the cycle of the printing structure 3 reciprocatingly moving in the vertical direction, and each protection frame 601 stops moving and waits for the drying air box 501 to dry when it switches to the drying air box 501.

[0059] Through the linkage design of the printing and gluing structure 4, the present invention enables the gluing part and the printing part to move synchronously in the vertical direction. The glue gun 403 applies glue precisely at the edge of the label, seamlessly connecting with the printing action, reducing the idle time of the equipment. At the same time, during the subsequent drying process after gluing, the continuously moving glue protection structure 6 prevents the glue from curing prematurely under the influence of drying. By setting the printing and gluing processes to be synchronized and protecting the glue during the drying process through the glue protection structure 6, the present invention eliminates the time waiting for the gluing equipment to work and improves work efficiency.

[0060] Specifically, as Figures 1 to 8 shown, the gluing structure 4 involved in the present invention further includes guide rods 404 and telescopic rods 405. The two guide rods 404 are respectively installed on both sides of the printing device 301. The guide rods 404 are wavy round rods. The mounting block 402 is slidably connected to the guide rods 404. The telescopic rod 405 is installed on the mounting block 402, and the other end of the telescopic rod 405 is installed on the output end of the second linear driving device 401. The telescopic rod 405 is used to enable the mounting block 402 to reciprocate along the guide rod 404 when driven by the second linear driving device 401.

[0061] Through the wavy round rod-shaped guide rod 404 and the telescopic rod 405, since the guide rod 404 is wavy, the mounting block 402 will reciprocate along the wavy track through the telescopic rod 405 during the movement. The glue gun 403 is installed on the mounting block 402. Therefore, the glue gun 403 will also move along a wavy path accordingly. When gluing a label with a wavy shape is required, the movement path of the glue gun 403 can be made to match the wavy edge of the label. For labels with different wavy shapes and different sizes, only by changing the shape of the guide rod 404 or adjusting the driving mode of the second linear driving device 401, the adjustment of the gluing path can be easily achieved. The design of the wavy round rod-shaped guide rod 404 and the telescopic rod 405 of the present invention provides a more flexible and precise solution for label gluing operations, and can effectively improve the gluing quality and production efficiency of labels.

The auxiliary slide bar 605 slides on the auxiliary rail 606 having the same structure as the walking rail 604 to provide auxiliary support for the movement of the protection frame body 601.
