Description

Technical Field

[0001] This utility model belongs to the field of printing and packaging technology, specifically relating to packaging equipment and thermal printers. Background Technology

[0002] Packaging equipment and thermal printers are integrated devices that combine thermal printing and post-packaging processing functions. The core of the device is to complete information output through thermal printing technology and simultaneously protect the printed products through a matching packaging structure, thus fulfilling the integrated needs of "printing and packaging".

[0003] Currently, packaging equipment and thermal printers on the market typically use thermal printheads to heat thermal materials such as thermal paper, causing a chemical change in the material coating to display text, images, and other information. This method can quickly print product labels without the need for ink or ribbons, and is fast and easy to operate. However, the surface of thermal paper relies solely on its own thermal coating for color development and lacks additional protective structures. Once exposed to rain or humid environments, the coating is prone to dissolving or fading due to water, resulting in blurred text and images. During logistics handling and warehousing stacking, if the thermal paper rubs or scratches against other items, or comes into contact with external contaminants such as oil or dust, it will directly damage the printed information. This will lead to the loss of critical information such as product labels and logistics tags, which will not only affect subsequent product traceability, warehousing management, and logistics distribution efficiency, but may also cause misdelivery or omission of goods due to unclear information, thereby creating compliance risks and safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a packaging device and a thermal printer that can quickly cover the thermal paper with a transparent protective film after printing, effectively isolating the thermal coating from moisture and humid environments, preventing the coating from dissolving or fading, ensuring the long-lasting clarity of text and patterns, and protecting the printed information from damage.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A thermal printer includes a printer body, with rectangular plates fixedly connected to both sides of the top of the printer body. Thermal paper is installed on one end of the printer body near the rectangular plates, and a waterproof coating component and a cutting component are provided on the rectangular plates.

[0007] Preferably, the waterproof membrane assembly includes rectangular grooves formed at the top and bottom of two rectangular plates on opposite sides. Rectangular blocks are inserted into both the top and bottom rectangular grooves. Each rectangular block is rotatably connected to a gear. The gears at the top and bottom are meshed together. A single-sided adhesive waterproof membrane is fixedly installed on the side of each pair of gears that are close to each other. Clamping blocks are fixedly connected to the opposite sides of the two rectangular plates. Both sides of the two single-sided adhesive waterproof membranes and the thermal paper are slidably inserted into the clamping blocks.

[0008] Preferably, the cutting assembly includes a slide rod fixedly connected to one side of two rectangular plates that are close to each other, a slider slidably connected to the surface of the slide rod, a spring fixedly connected to the bottom of the slider, and a cutter fixedly connected to the end of the spring away from the slider.

[0009] Preferably, a limiting plate is fixedly connected to one side of the two rectangular plates that are close to each other and located at the bottom of the slide rod, and the top of the limiting plate is provided with a sliding groove for use with the cutter.

[0010] Preferably, a stop plate is fixedly connected to one side of each of the two printer bodies, and one end of the thermal paper and the single-sided adhesive waterproof membrane passes through the clamping block and the stop plate in sequence.

[0011] Preferably, each of the rectangular plates has a T-shaped groove at its top and bottom, and a glass plate is slidably inserted into the T-shaped groove on both sides of the rectangular plate. Each glass plate is threadedly connected to the rectangular plate with a threaded rod, and the glass plate has an L-shaped structure.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a packaging device and a thermal printer. By setting up a waterproof coating component and a cutting component, a single-sided adhesive waterproof film and thermal paper are inserted into a clamping block. After manually pulling one end of the single-sided adhesive waterproof film and thermal paper, a gear drives the single-sided adhesive waterproof film to flatly adhere to the surface of the thermal paper, thereby achieving a coating process on the thermal paper, improving its waterproof performance and preventing information from becoming blurred or damaged due to friction and scratches. By pushing a slider, a spring drives a cutter to cut along the groove of a limiting plate, ensuring precise cutting of the coated thermal paper and avoiding cutting deviation and shaking. After the thermal paper is printed, the device can quickly cover it with a transparent protective film, effectively isolating it from moisture and humid environments, preventing the coating from dissolving or fading, ensuring the long-lasting clarity of text and patterns, and protecting the printed information from damage.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1 - Figure 4 As shown, a thermal printer includes a printer body 1, with rectangular plates 2 fixedly connected to both sides of the top of the printer body 1. Thermal paper 3 is installed on one end of the printer body 1 near the rectangular plates 2. A waterproof coating component and a cutting component are provided on the rectangular plates 2.

[0023] The printer body 1 can quickly print out preset thermal paper 3 by operating the printer body 1. The printed thermal paper 3 is then coated with a waterproof coating component to enhance its waterproof performance, protect it from moisture erosion, and ensure that the information on the thermal paper 3 is clearly visible and durable. The cutting component is located after the waterproof coating component, allowing the user to accurately cut the coated thermal paper 3 as needed to meet different size requirements. This results in neat and aesthetically pleasing edges for the thermal paper 3, improving printing and packaging efficiency.

[0024] like Figure 1As shown, the membrane waterproofing assembly includes rectangular grooves 4 formed at the top and bottom of two rectangular plates 2 on opposite sides. Rectangular blocks 5 are inserted into both the top and bottom rectangular grooves 4. Gears 6 are rotatably connected to each rectangular block 5. The top and bottom gears 6 are meshed together. A single-sided adhesive waterproof membrane 7 is fixedly installed on the side of each pair of gears 6 that is close to each other. Clamping blocks 8 are fixedly connected to the opposite sides of the two rectangular plates 2. The two single-sided adhesive waterproof membranes 7 and the thermal paper 3 are slidably inserted into the clamping blocks 8 on both sides.

[0025] Specifically, the single-sided adhesive waterproof membrane 7 has an adhesive layer on the side aligned with the thermal paper 3 to ensure a tighter fit. During operation, the single-sided adhesive waterproof membrane 7 and the thermal paper 3 are manually inserted into the clamps 8 on both sides of the rectangular plate 2. Then, one end of the single-sided adhesive waterproof membrane 7 and the thermal paper 3 is pinched and pulled outwards, causing the gears 6 at the top and bottom to mesh and rotate. This causes the single-sided adhesive waterproof membrane 7 to slide within the clamps 8 and adhere to the surface of the thermal paper 3. Finally, the single-sided adhesive waterproof membrane 7 is smoothly covered on the top and bottom of the printed thermal paper 3, completing the lamination operation. The design of the single-sided adhesive waterproof membrane 7 improves the waterproof performance of the thermal paper 3 and effectively prevents information blurring or damage caused by friction or scratches, ensuring that the information on the thermal paper 3 remains clearly visible in any environment.

[0026] like Figure 2 and Figure 3 As shown, the cutting assembly includes a slide bar 9 fixedly connected to one side of two rectangular plates 2 that are close to each other. A slider 10 is slidably connected to the surface of the slide bar 9. A spring 11 is fixedly connected to the bottom of the slider 10. A cutter 12 is fixedly connected to the end of the spring 11 away from the slider 10.

[0027] The cutter 12 is a sharp blade used to precisely cut the laminated thermal paper 3. After the lamination operation is completed, the user can push the slider 10 to slide on the slide bar 9. The spring force of the spring 11 will insert the cutter 12 into the bottom of the single-sided adhesive waterproof membrane 7 and the thermal paper 3 to cut them. During the cutting process, the sharp edge of the cutter 12 can easily penetrate the single-sided adhesive waterproof membrane 7 and the thermal paper 3, achieving a clean and neat cutting effect. This facilitates the cutting needs of thermal paper 3 of different sizes and further enhances the practicality and flexibility of the device.

[0028] like Figure 3 and Figure 4 As shown, a limiting plate 13 is fixedly connected to one side of the two rectangular plates 2 that are close to each other and located at the bottom of the slide bar 9. The top of the limiting plate 13 is provided with a groove that works with the cutter 12.

[0029] Specifically, the design of the chute is intended to guide the movement path of the cutter 12 during the cutting process, ensuring the accuracy and stability of the cut. When the slider 10 slides on the slide bar 9, the cutter 12 will cut along the chute at the top of the limiting plate 13, which can effectively prevent deviation or shaking during the cutting process, thereby ensuring the straightness of the cutting line and the flatness of the cutting edge, improving work efficiency and product quality.

[0030] like Figure 3 and Figure 4 As shown, a backing plate 14 is fixedly connected to one side of the two printer bodies 1 facing each other, and one end of the thermal paper 3 and the one-sided adhesive waterproof membrane 7 passes through the clamping block 8 and the backing plate 14 in sequence.

[0031] The design of the backing plate 14 mainly serves to guide and fix the thermal paper 3 and the single-sided adhesive waterproof membrane 7 during the lamination and cutting process. The thermal paper 3 and the single-sided adhesive waterproof membrane 7 pass through the clamping block 8 first and then smoothly enter the backing plate 14, ensuring the stability and accuracy of the thermal paper 3 and the single-sided adhesive waterproof membrane 7 during the transmission process, and avoiding uneven lamination or cutting errors caused by positional deviation or shaking.

[0032] like Figure 1 As shown, each rectangular plate 2 has a T-shaped groove 15 at its top and bottom. A glass plate 16 is slidably inserted into the T-shaped groove 15 and located on both sides of the rectangular plate 2. Each glass plate 16 is threadedly connected to the rectangular plate 2 by a threaded rod 17. The glass plate 16 has an L-shaped structure.

[0033] Specifically, the glass plate 16 is slidably installed on both sides of the rectangular plate 2 via the T-slot 15, and is fixed to the rectangular plate 2 by the threaded rod 17. The glass plate 16 is designed to protect both sides of the rectangular plate 2, and also to protect the uncoated areas of the adhesive waterproof membrane 7 and thermal paper 3 on one side, preventing damage or contamination to these areas. The threaded connection of the threaded rod 17 is detachable, making it easy to replace the adhesive waterproof membrane 7 on one side.

[0034] The working principle of this utility model is as follows: First, the preset thermal paper 3 is printed out by operation. Then, the single-sided adhesive waterproof membrane 7 and the thermal paper 3 are inserted into the clamps 8 on both sides of the rectangular plate 2. The single-sided adhesive waterproof membrane 7 and one end of the thermal paper 3 are manually pulled to make the top and bottom gears 6 mesh and rotate, thereby driving the single-sided adhesive waterproof membrane 7 to adhere to the surface of the thermal paper 3 to form a film, so as to enhance the waterproofness and wear resistance.

[0035] After the film coating is completed, push the slider 10 to slide along the slide bar 9. The spring 11 provides elastic force to make the cutter 12 cut the thermal paper 3 precisely along the groove of the limiting plate 13, thereby completing the film coating protection of the thermal paper 3.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
