Abstract
Description
Technical Field
[0001] This utility model relates to the field of label printing technology, specifically to a label ribbon integrated box structure. Background Technology
[0002] With increasingly frequent business activities, the demands for printing efficiency, ease of operation, and cost control are rising. To overcome the drawbacks of separate ribbon and label paper supply in traditional label printing methods, the integrated label ribbon cartridge structure has emerged. This integrated cartridge structure combines the ribbon and label paper into a single unit. Through optimized internal structural design, precise synchronization of ribbon and label paper supply is achieved. Furthermore, installation is simple: just install the entire cartridge onto the printer, greatly simplifying the installation process and reducing the probability of installation errors.
[0003] Common label cartridges involve inserting the paper roll directly into the cartridge and then pulling out the head. This lack of restraint on the paper roll during use makes it prone to retraction due to vibration or shaking, preventing the paper roll from being pulled out smoothly. This severely impacts the ease of use of the integrated label cartridge. Furthermore, the lack of a tensioning mechanism to ensure the ribbon remains taut during the supply and recycling of the ribbon affects the printing quality and fails to meet the requirements of label printing. Therefore, a new integrated label ribbon cartridge structure is proposed. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides an integrated label ribbon box structure to solve the technical problem that, since the paper roll is directly inserted into the box and then the head is pulled out, the paper roll lacks restraint in actual use, making it prone to retraction due to vibration or shaking during use.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated label ribbon box structure, comprising:
[0008] The lower housing has an upper housing mounted on its top. An annular seat is installed at the middle of the bottom of the inner cavity of the upper housing, and a paper roll is sleeved on the outside of the annular seat.
[0009] A shaft holder is installed on the front and rear sides of the right side of the inner cavity of the upper housing. A ribbon supply shaft is engaged with the outside of the front shaft holder, and a ribbon recovery shaft is engaged with the outside of the rear shaft holder. A ribbon roll is wound around the outside of the ribbon supply shaft.
[0010] A slot is connected to the rear left side of the inner cavity of the upper housing. An arc-shaped baffle is installed on the rear right side of the inner cavity of the upper housing. A transparent spring is inserted into the inside of the slot.
[0011] An assembly shaft is inserted inside the ribbon supply shaft. The inner wall of the ribbon supply shaft is circumferentially equipped with retaining teeth. A torsion spring is sleeved on the upper outer side of the assembly shaft. The bottom end of the assembly shaft is connected to the corresponding shaft holder.
[0012] Preferably, an assembly hole is provided at the middle position of the outer side of the lower housing, and solder joints are provided on both sides of the inner side of the assembly hole. A chip is inserted into the inner side of the assembly hole, and the added solder joints facilitate the assembly of the chip.
[0013] Preferably, a limiting groove is formed on the outer side of the upper housing corresponding to the outer side of the transparent spring. The transparent spring is inserted into the limiting groove and the slot. The head of the paper roll passes through the position between the transparent spring and the arc-shaped baffle. The slot improves the stability of the assembly of the transparent spring.
[0014] Preferably, the number of the retaining teeth is 3-6 sets, the upper head of the torsion spring is connected to a protruding strip, the protruding strip is engaged between the retaining teeth, and the lower tail of the torsion spring is connected to the corresponding position on the outside of the assembly shaft, which facilitates the rotation of the torsion spring through the retaining teeth and the protruding strip when the ribbon supply shaft rotates.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides an integrated label ribbon box structure, which has the following advantages:
[0017] 1. The integrated label and ribbon box structure, with the addition of a transparent spring, can clamp and limit the paper roll after it is inserted by means of an arc-shaped baffle and a transparent spring. This makes the paper roll resisted during the pulling process by the elastic compression of the transparent spring, preventing it from retracting and making it impossible to pull out during use, thus improving the convenience of using the integrated label box.
[0018] 2. The integrated ribbon cartridge structure of this label features a ribbon supply shaft that winds the ribbon around its exterior and a ribbon recovery shaft that collects the used ribbon. The ribbon supply shaft also incorporates an assembly shaft and a torsion spring. When the ribbon supply shaft rotates, the internal locking teeth push the torsion spring to rotate, causing it to slip on the assembly shaft and rotate synchronously. This creates resistance as the ribbon supply shaft rotates, keeping the ribbon taut and improving printing quality. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a technical solution: an integrated label ribbon box structure, including a lower shell 1, an upper shell 2, an annular seat 3, a paper roll 4, a shaft holder 5, a ribbon supply shaft 6, a retaining tooth 61, a ribbon recycling shaft 7, a slot 8, an arc-shaped baffle 9, a transparent spring 10, a limiting groove 11, an assembly shaft 12, a torsion spring 13, a protruding strip 131, an assembly hole 14, a chip 15, a limiting spring 16, and a ribbon roll 17.
[0029] Please see Figure 1 and Figure 2 The upper housing 2 is mounted on the top of the lower housing 1. Please refer to [link / reference]. Figure 3 An annular seat 3 is installed at the middle position of the bottom of the inner cavity of the upper housing 2. Please refer to [link / reference]. Figure 2 The outer side of the annular seat 3 is fitted with a paper roll 4. Please refer to [link / reference]. Figure 1 and Figure 2 An assembly hole 14 is provided at the middle position of the outer side of the lower housing 1. Solder points are provided on both sides of the inner side of the assembly hole 14. A chip 15 is inserted into the inner side of the assembly hole 14.
[0030] Shaft holders 5 are installed on the front and rear sides of the right side of the inner cavity of the upper housing 2. The front shaft holder 5 is externally engaged with a ribbon supply shaft 6, and the rear shaft holder 5 is externally engaged with a ribbon recovery shaft 7. Please refer to [link / reference]. Figure 5 A ribbon roll 17 is wound around the outside of the ribbon supply shaft 6;
[0031] Please see Figure 3 The slot 8 is connected to the rear left side of the inner cavity of the upper housing 2. An arc-shaped baffle 9 is installed on the rear right side of the inner cavity of the upper housing 2. A transparent spring 10 is inserted into the inside of the slot 8. Please refer to [link / reference]. Figure 4 A limiting groove 11 is provided on the outer side of the upper shell 2, corresponding to the outer side of the transparent spring 10. The transparent spring 10 is inserted into the limiting groove 11 and the slot 8. The head of the paper roll 4 passes through the position between the transparent spring 10 and the arc-shaped baffle 9. After the paper roll 4 is inserted, the arc-shaped baffle 9 and the transparent spring 10 can clamp and limit the paper roll 4. This makes the paper roll 4 generate resistance due to the elastic compression of the transparent spring 10 during the pulling process, preventing it from retracting during use and making it impossible to pull out the paper roll 4, thus improving the convenience of using the label box.
[0032] Please see Figure 6 and 7 An assembly shaft 12 is inserted inside the ribbon supply shaft 6. The inner wall of the ribbon supply shaft 6 is circumferentially equipped with retaining teeth 61. A torsion spring 13 is sleeved on the upper outer side of the assembly shaft 12. The bottom end of the assembly shaft 12 is connected to a corresponding shaft retainer 5. The number of retaining teeth 61 is 3-6 sets. A protruding strip 131 is connected to the upper head of the torsion spring 13, and the protruding strip 131 engages with the retaining teeth 61. The lower tail of the torsion spring 13 is connected to the corresponding position on the outside of the assembly shaft 12. The ribbon supply shaft 6, through which the ribbon can be supplied, can be fed... The ribbon roll 17 is wound around its outside, and the used ribbon is retrieved by the added ribbon recovery shaft 7. At the same time, since the ribbon supply shaft 6 has an assembly shaft 12 and a torsion spring 13 inserted inside, when the ribbon supply shaft 6 rotates, the torsion spring 13 can be pushed to rotate by the added retaining teeth 61 inside, so that the torsion spring 13 slips on the assembly shaft 12 and rotates synchronously. This creates resistance when the ribbon supply shaft 6 rotates, and this resistance can keep the ribbon tightly taut, improving the printing effect.
[0033] This solution uses a transparent spring 10 to clamp and limit the paper roll 4 after it is inserted, through the arc-shaped baffle 9 and the transparent spring 10. This creates resistance during the pulling process of the paper roll 4 due to the elastic compression of the transparent spring 10, preventing it from retracting and becoming impossible to pull out during use, thus improving the convenience of using the label box. At the same time, the added ribbon supply shaft 6 can wrap the ribbon roll 17 around its outside, and the added ribbon recovery shaft 7 can recover the used ribbon. Since the ribbon supply shaft 6 has an assembly shaft 12 and a torsion spring 13 inserted inside, when the ribbon supply shaft 6 rotates, the added retaining teeth 61 push the torsion spring 13 to rotate, causing the torsion spring 13 to slip on the assembly shaft 12 and rotate synchronously. This creates resistance when the ribbon supply shaft 6 rotates, and this resistance can keep the ribbon tightly taut, improving the printing effect.
