[0027] Reference Figure 1-7 The image shown is a preferred embodiment of the present invention.

[0028] The paper-adaptive label printer includes a paper tray 2 and an adjustment structure 1. The paper tray 2 is used to hold the printing roll paper. The adjustment structure 1 includes two tray plates 11, two toothed conditions 12, and a rotating gear 13. The rotating gear 13 is movably installed. The two toothed conditions 12 correspond one-to-one with the two tray plates 11 and are assembled. The two toothed conditions 12 are respectively meshed with the rotating gear 13. The two tray plates 11 are respectively movably embedded in the paper tray 2. The two tray plates 11 are moved along opposite or opposite directions under driving force. The two tray plates 11 are used to clamp and position the printing roll paper.

[0029] In practical use, the user can adjust the distance between the two tray plates 11 according to the specifications of the printing paper 3 to accommodate different sizes of printing paper 3. At the same time, the gear condition 12 and the rotating gear 13 work together to limit the adjustment of the distance between the two tray plates 11, improving the clamping stability of the tray plates 11 on the printing paper 3. Furthermore, the distance adjustment of the tray plates 11 is unrestricted, which can accommodate various sizes of printing paper 3, making the printer more adaptable and expanding its application scenarios.

[0030] The paper storage unit 2 has a storage transfer groove 21, which is arranged in a long strip along the moving direction of the storage plate 11. The storage plate 11 includes a main body and a raised plate 111. The main body and the raised plate 111 are connected and integrally formed. The raised plate 111 is movably embedded in the storage transfer groove 21, and the outer surface of the raised plate 111 is in contact with the groove wall of the storage transfer groove 21.

[0031] The convex plate 111 and the storage transfer groove 21 work together to position and guide the movement of the storage plate 11, improve the stability of the movement of the storage plate 11, and effectively prevent the storage plate 11 from shaking during movement.

[0032] The paper storage unit 2 has two storage transfer grooves 21. Along the moving direction of the storage plate 11, the storage transfer grooves 21 are arranged in a long strip shape, and the two storage transfer grooves 21 are arranged at intervals. The two storage plates 11 and the two storage transfer grooves 21 are arranged in a one-to-one correspondence. The storage plate 11 includes a main body and a raised plate 111. The main body and the raised plate 111 are connected and integrally formed. The raised plate 111 is movably embedded with the storage transfer groove 21, and the outer surface of the raised plate 111 is in contact with the groove wall of the storage transfer groove 21.

[0033] In this way, under the constraint of the two storage transfer grooves 21, collisions are avoided when the two storage plates 11 move towards each other, and the moving distance of the two storage plates 11 in the opposite direction is limited. At the same time, through the cooperation of the two storage plates 11 and the two storage transfer grooves 21, the movement of the two storage plates 11 is simultaneously limited and guided, improving the movement stability of the storage plates 11 and effectively preventing the storage plates 11 from shaking during movement.

[0034] The paper storage unit 2 has a recessed groove 22, which is arranged to be recessed downwards and extends in a long strip along the moving direction of the storage plate 11. The storage plate 11 includes a toothed portion 112, which is arranged above the protruding plate 111 and protrudes outwards. The toothed portions 112 of the two storage plates 11 are synchronously engaged with the recessed groove 22.

[0035] By engaging the locking groove 22 with the two toothed portions 112, the movement of the bin plate 11 is positioned and guided, improving the stability of the bin plate 11. At the same time, the combination of the locking groove 22 and the bin shifting groove 21 limits and guides the bin plate 11 at different positions, enhancing the limiting effect of the bin plate 11 and improving the smoothness of the bin plate 11's movement.

[0036] The bin plate 11 includes a bottom fixing strip 113, which is arranged at the bottom and is long in shape along the moving direction of the bin plate 11. The bottom fixing strip 113 is movably embedded with the paper bin component 2.

[0037] In this way, with the combined action of the bottom fixing bar 113, the trap fixing groove 22 and the warehouse transfer groove 21, the area is limited and guided by the warehouse plate 11, which greatly enhances the limiting effect of the warehouse plate 11 and ensures the smooth movement of the warehouse plate 11.

[0038] The paper tray component 2 has a bottom tray groove 23, which is arranged in a long strip shape. The bottom fixing strip 113 is movably embedded in the bottom tray groove 23. The bottom tray groove 23 plays a limiting and guiding role for the bottom fixing strip 113, thereby improving the linearity and stability of the tray plate 11.

[0039] The adjustment structure 1 includes a push rod 14, which is movably mounted on the bin plate 11. The upper part of the push rod 14 forms a push rod head 142, and the lower part of the push rod 14 forms a fixed rod head 143. The gear condition 12 has multiple rack grooves 121. The push rod head 142 is used to receive the pushing force to drive the fixed rod head 143 to engage with or disengage from the rack grooves 121.

[0040] In this way, after the user adjusts the two trays 11 into place, by applying a pushing force to the push rod head 142, the fixed rod head 143 is made to engage with the rack groove 121, thereby limiting the tooth condition 12. At this time, the tooth condition 12 is relatively fixed, preventing the tooth condition 12 from moving erroneously and affecting the tray 11's gripping of the printing paper 3. When the spacing needs to be adjusted, the push rod 14 is pulled up, causing the fixed rod head 143 to disengage from the rack groove 121. At this time, the tooth condition 12 is in an active state, making the tray 11 movable, thereby realizing the adjustment of the position of the tray 11.

[0041] The pusher head 142 has a pusher face, which is arranged on the side to facilitate the user to apply pushing or pulling force to the pusher face. The pusher face is provided with multiple pusher protrusions, which are arranged at intervals and are protruding. Under the action of the pusher protrusions, the friction is enhanced, making it easier for the user to apply pushing or pulling force.

[0042] The lower part of the fixed rod head 143 forms a fixed head tooth assembly, and the rack groove 121 has a rack tooth assembly. The rack tooth assembly and the fixed head tooth assembly are arranged in an engaging or disengaging manner. In this way, when the fixed state is maintained, the fixing effect is enhanced by the cooperation between the rack tooth assembly and the fixed head tooth assembly.

[0043] The push rod 14 includes a rod body 144, the two ends of which are respectively connected to the push rod head 142 and the fixed rod head 143 and are integrally formed; the bin plate 11 includes a push plate part, the push rod 14 is movably installed on the push plate part, the push plate part includes a push plate strip, the push plate strip is arranged correspondingly to the rod body 144, the rod body 144 has a rod protrusion 141, the rod protrusion 141 is arranged protruding away from the rod body 144, the push plate strip has a plate protrusion 114, the plate protrusion 114 is arranged protruding in the direction towards the push plate strip, the two ends of the plate protrusion 114 respectively form a block fixing groove, the block fixing groove is used for the rod protrusion 141 to be embedded.

[0044] In this way, regardless of whether it is in the active or fixed state, the cooperation between the rod protrusion 141 and the block groove plays a role in positioning and fixing the active or fixed state, avoiding accidental switching of the state and avoiding affecting the normal adjustment of the bin plate 11.

[0045] The adjustment structure 1 includes two return springs, which are arranged in a one-to-one correspondence with the two chamber plates 11. One end of the return spring is fixed, and the other end of the return spring is connected to the chamber plate 11. When the two chamber plates 11 move towards each other, the return spring is in a compressed state.

[0046] In this way, when the force applied to the tray 11 is removed, the two trays 11 are moved in opposite directions by the action of the return spring, thereby resetting the two trays 11 and facilitating the placement of the printing paper 3.

[0047] Meanwhile, when it is necessary to replace the printing paper 3, a pushing force is applied to the push rod 14 until the tooth condition 12 is in an active state. Under the action of the return spring, the two compartment plates 11 move in opposite directions, which facilitates the removal of the paper tube after the printing paper 3 has been used up and the placement of the new printing paper 3.

[0048] The tooth condition 12 includes a rack segment and a tooth fixing part. The rack segment is arranged in a long strip shape, and the rack segment and the tooth fixing part are connected and integrally formed. The tooth fixing part is assembled with the paper bin component 2. The rack segment is meshed with the rotating gear 13, and the rotating gear 13 is located between the two rack segments.

[0049] This design minimizes the space required for the assembly and unfolding of the two toothed conditions 12, and facilitates the cooperation between the two toothed conditions 12 and the rotating gear 13, enabling the synchronous movement of the two chamber plates 11.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
