Description

Technical Field

[0001] This utility model relates to the field of label printing technology, and in particular to a portable label printer. Background Technology

[0002] Label printers can imprint selected characters or numbers onto tape labels. The principle behind this is that the tape label is passed between a concave die plate and a convex die plate. The concave or convex die plate is manually pressed against the tape label, causing plastic deformation, thus imprinting the selected characters or numbers. Existing label printers have the following problem: after imprinting, the surface of the tape label undergoes plastic deformation and becomes stuck between the concave and convex dies, making tape feeding difficult and affecting usability. Utility Model Content

[0003] To achieve the above objectives, this utility model provides a portable label printer, comprising:

[0004] The housing has a cavity inside for holding the label tape;

[0005] A punch plate is rotatably mounted on the housing. The punch plate is provided with a plurality of elastic claws evenly distributed in the circumferential direction. The upper end surface of the elastic claws is formed with embossed patterns.

[0006] A concave die plate is disposed on the housing and located above the convex die plate. The concave die plate rotates synchronously with the convex die plate. The lower end surface of the concave die plate has a recessed pattern corresponding to the embossed pattern. One end of the label tape passes between the embossed pattern and the recessed pattern.

[0007] An operating handle is hinged to the housing. The operating handle can drive the elastic claw to undergo elastic deformation so that it presses against the label tape. The embossed pattern and the recessed pattern cooperate to imprint embossed marks on the label tape.

[0008] The housing is also fixedly mounted with an elastic sheet, one end of which is always pressed against the elastic claw, so that the embossed pattern always tends to move away from the recessed pattern.

[0009] In some possible embodiments, the housing has a tape outlet, and the elastic sheet is disposed at the tape outlet and presses against the elastic claw at an angle downwards.

[0010] In some possible embodiments, at least one positioning post is provided on the housing at the lower end of the tape outlet, one end of the elastic sheet is provided with a mounting hole and sleeved on the positioning post, and the other end is formed to be bent at at least at an acute angle and extend obliquely downward to press against the elastic claw.

[0011] In some possible embodiments, a guide channel is provided inside the housing, the upper end of the guide channel extending horizontally to near the punch / die platen, and one end of the label tape passes through the guide channel between the embossed pattern and the recessed pattern.

[0012] In some possible embodiments, a drive wheel and a clamping wheel are also provided at the middle position of the guide channel. The clamping wheel presses the label tape onto the surface of the drive wheel, and the operating handle can drive the drive wheel to rotate in one direction.

[0013] In some possible embodiments, the drive wheel is fixedly connected to a ratchet via a connecting rod, a locking pawl is provided inside the housing to engage the ratchet, and a drive pawl extends from the operating handle to abut against the ratchet. Both the locking pawl and the drive pawl can undergo elastic deformation.

[0014] In some possible embodiments, the upper end of the operating handle is provided with an operating claw, which can swing with the operating handle to press against the elastic claw and drive the elastic claw to undergo elastic deformation, and the operating claw can return to its original position with the operating handle to abut against and lock the drive wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The label printer of this utility model has an elastic sheet installed inside the housing. The elastic sheet always presses against the elastic claw to keep it away from the recessed pattern. When the operator presses the operating handle and the embossed pattern and recessed pattern match, after the embossed mark is printed on the label tape, the elastic sheet applies a force to the elastic claw through its own elastic restoring force, so that the embossed pattern automatically separates from the label tape after printing. This ensures that the label tape can be fed smoothly, avoiding jamming or requiring manual force to pull out the label tape, thus improving the user experience of the product.

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1 to 4The portable label printer shown includes a housing 10 and an operating handle 40 hinged to the housing 10. A cavity for holding a label tape 50 is formed inside the housing 10 or between the housing 10 and the operating handle 40. The housing 10 also has a punch plate 20 and a die plate 30, which can rotate synchronously to select the desired mark to be printed. The punch plate 20 has several circumferentially distributed elastic claws 21, each of which can independently undergo elastic deformation. The upper surface of each elastic claw 21 forms a raised printing pattern 22. The die plate 30 is located at the upper end of the punch plate 20, and its lower surface forms a recessed pattern 31 corresponding to the raised printing pattern 22. An elastic sheet 11 is also fixedly installed on the housing 10, and the elastic sheet 11 always presses against the elastic claws 21. The label printer of this utility model is used in... First, one end of the label tape 50 is passed between the embossed texture 22 and the recessed texture 31. The operator presses the operating handle 40 to lift the elastic claw 21. The embossed texture 22 and the recessed texture 31 on the elastic claw 21 cooperate to imprint embossed marks on the label tape 50. After the operator releases the operating handle 40, the operating handle 40 returns to its original position, and the elastic piece 11, through its own elastic restoring force, drives the elastic claw 21 / embossed texture 22 to separate from the lower surface of the label tape 50, avoiding the problem of the embossed texture 22 sticking to the label tape 50 and causing the tape to jam. It should be noted that in order to ensure that the operating handle 40 can quickly return to its original position after the operator releases the handle, it is a conventional and mature technical means to set a torsion spring on the operating handle 40. The structural connection design of the torsion spring between the operating handle 40 and the housing 10 can also adopt a conventional and mature method in the industry, so it will not be described in detail here.

[0024] In some possible embodiments, refer to Figure 1 and Figure 4 As shown, the housing 10 has a tape outlet 12. An elastic sheet 11 is disposed at the tape outlet 12 and presses against the elastic claw 21 at an angle downward. Specifically, the elastic claw 21 has an inclined abutment surface on the side near the elastic sheet 11. The elastic sheet 11 always presses against the inclined abutment surface and applies a force to the elastic claw 21, so that the elastic claw 21 always tends to move away from the die plate 30.

[0025] In some possible embodiments, at least one positioning post is provided on the housing 10 at the lower end of the tape outlet 12. One end of the elastic sheet 11 is provided with a mounting hole 13 that mates with the positioning post. One end of the elastic sheet 11 is sleeved on the positioning post through the mounting hole 13, and the other end is bent at least once at an acute angle and extends downward at an angle to press the elastic claw 21, thereby fixing the elastic sheet 11 in the housing 10. In this embodiment, the structural design of the elastic sheet 11 can enhance its elastic force and ensure that the elastic sheet 11 still exerts force on the elastic claw 21 after long-term use.

[0026] In some possible embodiments, refer to Figures 1 to 4 As shown, a guide channel 14 is provided inside the housing 10. The upper end of the guide channel 14 extends horizontally to the vicinity between the punch plate 20 and the die plate 30, so that the end of the label tape 50 can accurately pass between the embossed texture 22 and the recessed texture 31.

[0027] In some possible embodiments, refer to Figure 2 and Figure 4 As shown, a drive wheel 15 and a pressure wheel 16 are also provided in the middle of the guide channel 14. The drive wheel 15 and the pressure wheel 16 are connected in a drive manner. The label tape 50 passes between the drive wheel 15 and the pressure wheel 16. The drive wheel 15 can be driven to rotate by pressing the operating handle 40. The drive wheel 15 and the pressure wheel 16 cooperate to drive the label tape 50 to be conveyed along the guide channel 14 between the embossed texture 22 and the recessed texture 31.

[0028] Furthermore, refer to Figure 2 As shown, the drive wheel 15 is fixedly connected to the ratchet 17 via a connecting rod. A locking pawl 18 is provided inside the housing 10 to engage the ratchet 17. The locking pawl 18 is used to prevent the ratchet 17 from rotating only in one direction or only in the other, ensuring that the drive wheel 15 can only rotate in one direction. A drive pawl 41 extends from the operating handle 40 to abut against the ratchet 17. Both the locking pawl 18 and the drive pawl 41 can undergo elastic deformation. When a person presses the operating handle 40 to rotate it relative to the housing 10, the drive pawl 41 also rotates with the operating handle 40 and engages the ratchet 17. At this time, the locking pawl 18 locks the ratchet 17 / drive wheel 15 to prevent the drive wheel 15 from rotating. The label tape 50 is retracted, at which point the drive claw 41 is subjected to force and undergoes elastic deformation. At the same time, the operating handle 40 will also abut against the elastic claw 21 and make the embossed pattern 22 on the elastic claw 21 match the recessed pattern 31 on the die plate 30, thus imprinting an embossed mark on the label tape 50. After the imprinting is completed, the operator releases the operating handle 40, and the drive claw 41 also resets with the operating handle 40. During the reset process, the drive claw 41 can drive the ratchet 17 to rotate. When the ratchet 17 rotates, it can force the locking claw 18 to undergo elastic deformation, so that the ratchet teeth on the ratchet 17 can pass over the locking claw 18, ensuring that the ratchet 17 / drive wheel 15 can rotate and drive the label tape 50 to be conveyed forward.

[0029] Furthermore, refer to Figure 2As shown, the upper end of the operating handle 40 is provided with an operating claw 42. When the operator presses the operating handle 40, the operating claw 42 rotates relative to the housing 10 with the operating handle 40 and abuts against the elastic claw 21, so as to force the elastic claw 21 to undergo elastic deformation to achieve the embossing function. After the operator releases the operating handle 40, the operating claw 42 returns to its original position with the operating handle 40 and the side surface of the operating claw 42 abuts against the drive wheel 15 to lock the drive wheel 15. The label tape 50 is locked by the cooperation of the drive wheel 15 and the pressure wheel 16, so as to avoid the problem of poor printing consistency of the label tape 50 caused by one end of the label tape 50 being able to move relative to the embossed pattern 22 / recessed pattern 31 under normal conditions.

Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
