Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer consumables boxes, in particular to an integrated consumables box anti-retraction structure. Background Art

[0002] A thermal transfer consumables box is a consumable used in thermal transfer printing technology. It usually contains carbon ribbons, color ribbons and other materials that can print clear images and text on different printing media. At present, some integrated thermal transfer consumables boxes on the market have internal consumables that can easily return the paper roll to the paper bin box during transportation. This cannot effectively prevent the paper roll from returning, and an anti-return label needs to be affixed, which increases the workload. In actual user scenarios, when the labels in the consumables box are not used up and are taken out and placed for a period of time, the internal labels will return, causing the remaining labels to be unusable. During the transportation of full or half rolls, it is not easy to prevent the occurrence of label return, and manual adjustment is required later, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to provide an integrated consumables box anti-retraction structure to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An integrated consumable box anti-retraction structure, comprising:

[0006] The upper shell and the lower shell are capable of being snap-fitted to each other, and tongues are fixedly connected to the two outer side walls of the upper shell;

[0007] The paper roll has a roll core fixedly sleeved inside the paper roll, and the tongue piece can be movably engaged with the roll core.

[0008] Furthermore, a fixing block is fixedly connected to one side of the tongue piece, a clamping block is fixedly connected to the top of the fixing block, and a tooth groove is provided on the inner wall of the winding core, and the clamping block can be movably clamped with the tooth groove.

[0009] Preferably, a lower cover is provided below the lower shell, and both ends of the lower cover are fixedly connected with positioning plates, and the positioning plates can be movably engaged with the lower shell.

[0010] Furthermore, a limiting frame is fixedly connected between the two outer walls of the upper shell, a plurality of elastic plug plates are fixedly connected to the bottom of the limiting frame, reinforcing shells are fixedly connected to the two outer walls of the lower shell, docking shells are fixedly connected inside the two reinforcing shells, and the elastic plug plates can be movably connected to adjacent docking shells.

[0011] Preferably, the tongue piece and the elastic plug plate are made of TPE.

[0012] Furthermore, a cover plate is fixedly connected to one end of the limiting frame, a mounting frame is fixedly connected to the outer wall of the lower shell, and the cover plate can be movably engaged with the mounting frame.

[0013] Furthermore, the lower shell is internally rotatably connected to a supply-end ribbon shaft, the mounting frame is internally rotatably connected to a gear shaft, and both ends of the gear shaft are fixedly sleeved with a recovery-end ribbon shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. With tongues fixed on both sides of the upper shell, when the upper shell is placed in the machine, the paper bin cover inside the machine is closed, and the paper bin cover presses and deforms the tongue on the upper shell. The block on the top of the tongue is separated from the tooth groove inside the roll core, and the paper roll can be released from the limit and driven by the rubber roller. After the upper shell is taken out, the tongue automatically elastically resets and snaps into the tooth groove, thereby automatically limiting the paper roll, which can effectively prevent the paper roll from shaking inside and causing it to fall back, making it convenient to use;

[0016] 2. Through the setting of the elastic plug plate and the upper shell, the upper shell and the lower shell can be quickly connected, the assembly is convenient, and the normal paper feeding and unwinding are not affected. When the cover is closed and the paper is fed, the resistance will not be increased. The upper shell and the lower shell can be used to limit and protect the roll paper. The lower cover can be quickly connected with the lower shell through the positioning plate, making the overall structure of the equipment more compact and small, saving assembly costs, simple structure, and easy installation.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 In an embodiment of the utility model, an integrated consumable box anti-retraction structure includes an upper shell 10 and a lower shell 40. The upper shell 10 and the lower shell 40 can be snap-fitted to each other, and tongue pieces 101 are fixedly connected to the two outer walls of the upper shell 10; the inner part of the roll paper 30 is fixedly sleeved with a roll core 20, and the tongue piece 101 can be movably snap-fitted to the roll core 20.

[0025] Specifically, by fixing tongues 101 on both sides of the upper shell 10, when the upper shell 10 is placed in the machine, the paper bin cover 90 inside the machine is closed, and the paper bin cover 90 presses and deforms the tongue 101 on the upper shell 10, and the block 103 on the top of the tongue 101 is disengaged from the tooth groove 201 inside the winding core 20, and the paper roll 30 can be released from the limit and driven by the rubber roller. After the upper shell 10 is taken out, the tongue 101 automatically elastically resets and snaps into the tooth groove 201, thereby automatically adjusting the paper roll 30. The limiter can effectively prevent the paper roll 30 from shaking inside and causing it to fall back, which is convenient to use. The lower cover 50 is positioned and quickly docked with the lower shell 40 through the positioning plates 501 at both ends, making assembly more convenient. The lower shell 40 is installed on the docking shell 401 through the reinforcing shell 402, and multiple elastic plug plates 104 are aligned with adjacent docking shells 401 and then snapped in, so as to quickly dock the upper shell 10 and the lower shell 40, which makes assembly more convenient, the structure is compact and small, and the docking is stable.

[0026] Embodiment 1

[0027] like Figure 4-5 As shown, in this embodiment, a fixing block 102 is fixedly connected to one side of the tongue piece 101 , a clamping block 103 is fixedly connected to the top of the fixing block 102 , and a tooth groove 201 is opened on the inner wall of the winding core 20 , and the clamping block 103 can be movably clamped with the tooth groove 201 .

[0028] In this embodiment, the tongue 101 fixes the block 103 through the fixed block 102. The fixed height of the fixed block 102 makes it difficult for the block 103 to get stuck in the tooth groove 201 and make it difficult to disengage. After the tongue 101 is squeezed and deformed by the paper bin cover 90, the block 103 is pulled out from the tooth groove 201 through the fixed block 102, thereby releasing the rotation limit of the core 20, so that the core 20 and the roll paper 30 can be rotated and used freely.

[0029] like Figure 2 As shown, in this embodiment, the lower shell 40 is internally rotatably connected to the supply end ribbon shaft 60, and the mounting frame 403 is internally rotatably connected to the gear shaft 80, and both ends of the gear shaft 80 are fixedly sleeved with the recovery end ribbon shaft 70.

[0030] During specific implementation, the mounting frame 403 limits the rotation of the gear shaft 80, thereby limiting the rotation of the recovery end ribbon shaft 70. Before recycling, the recovery end ribbon shaft 70 needs to be cleaned to remove residual ribbon materials or other contaminants. If the recovery end ribbon shaft 70 is in good condition, they can be reused in production, which can not only reduce waste but also reduce costs.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, in order to make the device structure more compact and save assembly cost.

[0033] like Figure 1-3 As shown, in this embodiment, a lower cover 50 is provided below the lower shell 40, and both ends of the lower cover 50 are fixedly connected with positioning plates 501, and the positioning plates 501 can be movably connected with the lower shell 40, and the two outer walls of the upper shell 10 are fixedly connected with a limit frame 105, and the bottom of the limit frame 105 is fixedly connected with a plurality of elastic plug plates 104, and the two outer walls of the lower shell 40 are fixedly connected with a reinforcement shell 402, and the interiors of the two reinforcement shells 402 are fixedly connected with a docking shell 401, and the elastic plug plate 104 can be movably connected with the adjacent docking shell 401, and the tongue 101 and the elastic plug plate 104 is made of TPE, which is called thermoplastic elastomer. As a high-toughness plastic material, it is not easy to break when impacted or stretched. It can absorb and disperse energy and has good impact resistance and flexibility. It is suitable for manufacturing products that need to withstand large physical impacts or need to have good elasticity. It has the elasticity of rubber and the processing convenience of plastic. One end of the limit frame 105 is fixedly connected to the cover plate 106, and the outer wall of the lower shell 40 is fixedly connected to the mounting frame 403, and the cover plate 106 can be movably connected with the mounting frame 403.

[0034] During specific implementation, the lower cover 50 is positioned and quickly docked with the lower shell 40 through the positioning plates 501 at both ends, making assembly more convenient. The lower shell 40 is installed on the docking shell 401 through the reinforcing shell 402, and multiple elastic plug plates 104 are aligned with adjacent docking shells 401 and then snapped in, so that the upper shell 10 and the lower shell 40 are quickly docked, and the assembly is more convenient. The structure is compact and small, and the docking is stable, which can prevent the upper shell 10 and the lower shell 40 from separating when falling. It has high hardness and excellent wear resistance, so that the tongue 101 can adapt to repeated installation and disassembly, and is not easily damaged by bending, and can well adapt to the working conditions of equipment assembly. The cover plate 106 can be snapped with the mounting frame 403 to seal the top of the mounting frame 403, thereby protecting the transmission components inside it.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
