Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a multi-functional thermal printer. Background Technology

[0002] Existing thermal printers typically only have a single printing function, capable of printing text, numbers, barcodes, and other information on thermal tapes. However, they cannot perform further decorative processing on the printed tapes, such as engraving. When it is necessary to produce label products with three-dimensional effects or exquisite decorative patterns, it is often necessary to first use a thermal printer to print the basic information, and then transfer the printed tape to a specialized engraving machine for engraving. This separate processing method not only increases equipment investment costs and space occupation, but also has problems such as positioning errors when transferring tapes between different machines, low processing efficiency, and cumbersome manual operation. Especially when mass-producing high-end labels, the multi-machine operation process is complex and it is difficult to ensure the consistency of processing accuracy. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-functional thermal printer that can integrate thermal printing and engraving processing on the same device.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A multi-functional thermal printer includes: a cartridge for holding a tape; a printhead for thermal printing on the tape; a first conveying mechanism disposed upstream of the printhead for conveying the tape to the printhead; a second conveying mechanism disposed downstream of the printhead for continuing to convey the printed tape; a reciprocating drive mechanism disposed downstream of the second conveying mechanism for driving the tape to reciprocate; a lifting mechanism for controlling the first and second conveying mechanisms to switch between a pressed state and a released state; and an engraving mechanism for engraving the tape. During printing, the lifting mechanism keeps the first and second conveying mechanisms in a pressed state, and the tape is conveyed unidirectionally for printing. During engraving, the lifting mechanism releases the first and second conveying mechanisms, the reciprocating drive mechanism drives the tape to reciprocate, and the engraving mechanism engraves the reciprocating tape.

[0006] Furthermore, the first conveying mechanism includes a first drive roller and a first pressure roller; the second conveying mechanism includes a second drive roller and a second pressure roller; the lifting mechanism is used to control the lifting of the first pressure roller and the second pressure roller to achieve switching between the first conveying mechanism and the second conveying mechanism in a pressing state and a releasing state.

[0007] Furthermore, the lifting mechanism includes a lifting plate and a lifting drive component. The lifting plate is provided with a first support portion and a second support portion.

The drive component is used to drive the lifting plate to lift and lower to control the lifting and lowering movement of the first pressure roller and the second pressure roller.

[0008] Furthermore, the lifting drive component includes a motor, a reduction gear set, and an eccentric cam. The motor drives the eccentric cam to rotate through the reduction gear set. The eccentric cam has an arc-shaped section and a straight section. When the eccentric cam rotates, the arc-shaped section gradually lifts the lifting plate. When it is lifted to the highest position, the straight section remains in contact with the bottom of the lifting plate to maintain the stable position of the lifting plate.

[0009] Furthermore, the eccentric cam is a semi-circular cam, and its rotation axis is located at one end of the semi-circle.

[0010] Furthermore, a first elastic element is provided between the first support part and the first pressure roller, and a second elastic element is provided between the second support part and the second pressure roller. The first elastic element and the second elastic element are used to provide clamping force when the lifting plate rises, so that the first pressure roller and the second pressure roller respectively clamp the material strip with the first drive roller and the second drive roller.

[0011] Furthermore, the reciprocating drive mechanism includes a third drive roller, a third pressure roller, and a reciprocating drive motor. The reciprocating drive motor is connected to the third drive roller and is used to drive the third drive roller to rotate in both directions to realize the reciprocating movement of the material belt.

[0012] Furthermore, the output shaft of the reciprocating drive motor is directly connected to the first end of the third drive roller.

[0013] Furthermore, it also includes an intermediate drive shaft, which is connected to the third drive roller and to the first or second drive roller. The first and second drive rollers are connected by a second belt.

[0014] Furthermore, it also includes a cutting assembly disposed between the reciprocating drive mechanism and the engraving head, for cutting the strip after printing and engraving to obtain the finished product.

[0031] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Reference Figure 1-3 A multi-functional thermal printer includes a cartridge 100 for holding a tape; a printhead 200 for thermal printing on the tape; a first conveying mechanism 400, disposed upstream of the printhead 200, for conveying the tape to the printhead 200; a second conveying mechanism 500, disposed downstream of the printhead 200, for continuing to convey the printed tape; a reciprocating drive mechanism 600, disposed downstream of the second conveying mechanism 500, for driving the tape to reciprocate; and a lifting mechanism 700 for controlling the first conveying mechanism 400 and the second conveying mechanism 500. The feeding mechanism 500 switches between a clamping state and a releasing state; the engraving mechanism 800 is used to engrave the material strip; wherein, when printing is performed, the lifting mechanism 700 keeps the first conveying mechanism 400 and the second conveying mechanism 500 in a clamping state, and the material strip is conveyed in one direction for printing; when engraving is performed, the lifting mechanism 700 keeps the first conveying mechanism 400 and the second conveying mechanism 500 in a releasing state, the reciprocating drive mechanism 600 drives the material strip to move back and forth, and the engraving mechanism 800 engraves the reciprocating material strip.

[0033] It should be noted that the implementation process of the multi-functional thermal printer in this case is as follows: the material tape in the material box 100 is first conveyed to the print head 200 position through the first conveying mechanism 400. When printing is performed, the lifting mechanism 700 drives the first conveying mechanism 400 and the second conveying mechanism 500 to clamp the material tape. At this time, the material tape is conveyed unidirectionally through the print head 200 under the coordinated action of the first conveying mechanism 400 and the second conveying mechanism 500 to complete the thermal printing. The printed material tape continues to be conveyed to the reciprocating drive mechanism 600 position by the second conveying mechanism 500. When engraving is required, the lifting mechanism 700 switches the first conveying mechanism 400 and the second conveying mechanism 500 to the release state to release the clamping of the material tape. At this time, the reciprocating drive mechanism 600 starts to work and drives the material tape to reciprocate below the engraving mechanism 800. The engraving mechanism 800 can then perform engraving processing on this reciprocating material tape. For example, when making labels with text and patterns, the required text content is first thermally printed on the material strip by the print head 200. Then, the lifting mechanism 700 releases the clamping state of the conveying mechanism, the reciprocating drive mechanism 600 drives the printed material strip to move back and forth, and the engraving mechanism 800 performs contour engraving or decorative engraving on the material strip during the reciprocating movement, thereby realizing the composite processing function of printing and engraving on the same material strip.

[0034] It should be noted that the engraving mechanism 800 in this case specifically performs physical cutting or ablation processing on the surface of the material strip using an engraving cutter or laser engraving head. When the reciprocating drive mechanism 600 drives the material strip to move back and forth, the cutter or laser head of the engraving mechanism 800 can engrave grooves, cut out specific shapes, or create relief effects on the surface of the material strip. This physical engraving can add a three-dimensional and tactile effect to the material strip that has already been thermally printed.

[0035] In some embodiments, refer to Figure 1 , 3The first conveying mechanism 400 includes a first drive roller 410 and a first pressure roller 420; the second conveying mechanism 500 includes a second drive roller 510 and a second pressure roller 520; the lifting mechanism 700 is used to control the lifting of the first pressure roller 420 and the second pressure roller 520 to achieve the switching between the pressing state and the releasing state of the first conveying mechanism 400 and the second conveying mechanism 500. It should be noted that the first conveying mechanism 400 is formed by the first drive roller 410 and the first pressure roller 420, while the second drive roller 510 and the second pressure roller 520 form the second conveying mechanism 500. The lifting mechanism 700 achieves the switching between the pressing state and the releasing state by controlling the vertical lifting movement of the first pressure roller 420 and the second pressure roller 520. When the lifting mechanism 700 drives the first pressure roller 420 to descend, the first pressure roller 420 and the first drive roller 410 form a clamping engagement to press the material strip between the two rollers. Similarly, the lifting mechanism... When the second pressure roller 520 is driven to descend by the lifting mechanism 700, the second pressure roller 520 and the second drive roller 510 also form a clamping engagement to press the material strip. At this time, the rotation of the first drive roller 410 and the second drive roller 510 can effectively drive the pressed material strip to be conveyed in one direction. When the lifting mechanism 700 drives the first pressure roller 420 and the second pressure roller 520 to rise, the two pressure rollers separate from the corresponding drive rollers respectively, and the material strip is no longer clamped and constrained, thus being in a released state. At this time, the reciprocating drive mechanism 600 can freely drive the material strip to move back and forth without being hindered by the conveying mechanism.

[0036] In some embodiments, refer to Figure 2 , 45. The lifting mechanism 700 includes a lifting plate 710 and a lifting drive 720. The lifting plate 710 is provided with a first support part 711 and a second support part 712. The first support part 711 is used to support the first pressure roller 420, and the second support part 712 is used to support the second pressure roller 520. The drive is used to drive the lifting plate 710 to lift and lower to control the lifting and lowering movement of the first pressure roller 420 and the second pressure roller 520. It should be noted that the lifting plate 710 is driven to move vertically by the lifting drive component 720. The first support part 711 on the lifting plate 710 carries and supports the first pressure roller 420, and the second support part 712 carries and supports the second pressure roller 520. When the lifting drive component 720 drives the lifting plate 710 to move downward, the first support part 711 and the second support part 712 descend synchronously, thereby causing the first pressure roller 420 and the second pressure roller 520 to form a clamping fit with the first drive roller 410 and the second drive roller 510 respectively to clamp the material strip. When the lifting drive component 720 drives the lifting plate 710 to move upward, the first support part 711 and the second support part 712 rise synchronously, and the first pressure roller 420 and the second pressure roller 520 disengage from the corresponding drive rollers to release the clamping of the material strip. Throughout the process, the lifting drive component 720 ensures the smooth lifting and lowering of the lifting plate 710, thereby ensuring the synchronous movement of the first pressure roller 420 and the second pressure roller 520.

[0037] In some embodiments, refer to Figure 4 , 5The lifting drive component 720 includes a lifting motor 721, a reduction gear set 722, and an eccentric cam 723. The lifting motor 721 drives the eccentric cam 723 to rotate through the reduction gear set 722. The eccentric cam 723 has an arc-shaped section and a straight section. When the eccentric cam 723 rotates, the arc-shaped section gradually lifts the lifting plate 710. When it is lifted to the highest position, the straight section remains in contact with the bottom of the lifting plate 710 to maintain the stable position of the lifting plate 710. Specifically, after the lifting drive component 720 is started by the lifting motor 721, the speed is reduced and the torque is increased by the reduction gear set 722, which drives the eccentric cam 723 to start rotating. When the arc-shaped section of the eccentric cam 723 contacts the bottom of the lifting plate 710, the arc-shaped section gradually lifts the lifting plate 710 upward as the eccentric cam 723 continues to rotate. The first support part 711 and the second support part 712 on the lifting plate 710 rise synchronously, causing the first pressure roller 420 and the second pressure roller 520 to disengage from the corresponding drive rollers, thereby releasing the clamping of the material strip. When the eccentric cam 723 rotates to the straight section position, the straight section forms a plane abutting with the bottom of the lifting plate 710, maintaining the stability of the lifting plate 710 at the highest position. At this time, the first pressure roller 420 and the second pressure roller 520 remain in the released state, creating conditions for the operation of the reciprocating drive mechanism 600. When it is necessary to re-clamp the material strip, the lifting motor 721 rotates in the opposite direction, driving the eccentric cam 723 to rotate in the opposite direction through the reduction gear set 722, so that the arc section gradually lowers the position of the lifting plate 710 until the first pressure roller 420 and the second pressure roller 520 re-clamp the material strip.

[0038] In some embodiments, refer to Figure 5 The eccentric cam 723 is a semi-circular cam, and its rotation axis is located at one end of the semi-circle.

[0039] Specifically, the semi-circular cam sets the rotating shaft near one end of the semi-circular cam. When the lifting motor 721 drives the semi-circular cam to rotate around the rotating shaft through the reduction gear set 722, the distance between the outer arc of the semi-circular cam and the rotating shaft will continuously change with the rotation angle because the rotating shaft is off from the center of the semi-circular cam. When the semi-circular cam rotates to the position where the outer arc is farthest from the rotating shaft, the arc segment will lift the lifting plate 710 to the highest position. When the semi-circular cam continues to rotate to the position where the outer arc is closest to the rotating shaft or the straight segment contacts the bottom of the lifting plate 710, the lifting plate 710 will be at the lowest position. This allows the semi-circular cam to achieve smooth lifting and lowering of the lifting plate 710 during rotation and maintain stability at a specific angle position.

[0040] In some embodiments, refer to Figure 4 , 5A first elastic element 7111 is provided between the first support part 711 and the first pressure roller 420, and a second elastic element 7121 is provided between the second support part 712 and the second pressure roller 520. The first elastic element 7111 and the second elastic element 7121 are used to provide clamping force when the lifting plate 710 rises, so that the first pressure roller 420 and the second pressure roller 520 respectively clamp the material strip with the first drive roller 410 and the second drive roller 510. It should be noted that a first elastic element 7111 is installed between the first support part 711 and the first pressure roller 420, and a second elastic element 7121 is installed between the second support part 712 and the second pressure roller 520. When the lifting drive 720 drives the lifting plate 710 to descend, the first support part 711 and the second support part 712 descend synchronously. The first elastic element 7111 and the second elastic element 7121 are compressed to generate elastic force. This elastic force is transmitted to the first pressure roller 420 through the first support part 711 and to the second pressure roller 520 through the second support part 712. This causes the first pressure roller 420 to apply a clamping force in the direction of the first drive roller 410, and the second pressure roller 520 to apply a clamping force in the direction of the second drive roller 510. The material strip is firmly clamped between each set of rollers. When the lifting plate 710 rises, the compression of the first elastic element 7111 and the second elastic element 7121 decreases until it is completely released. The first pressure roller 420 and the second pressure roller 520 lose their clamping force and thus separate from the corresponding drive rollers to release the material strip. Specifically, the elastic element is preferably a spring.

[0041] In some embodiments, refer to Figure 2 , 3 The reciprocating drive mechanism 600 includes a third drive roller 610, a third pressure roller 620, and a reciprocating drive motor 630. The reciprocating drive motor 630 is connected to the third drive roller 610 and is used to drive the third drive roller 610 to rotate in both directions to achieve the reciprocating movement of the material strip. It can be understood that by establishing a transmission connection between the reciprocating drive motor 630 and the third drive roller 610, when the reciprocating drive motor 630 rotates in the forward direction, it drives the third drive roller 610 to rotate in the forward direction. The third drive roller 610 and the third pressure roller 620 cooperate to clamp the material strip and move it forward. When the reciprocating drive motor 630 rotates in the reverse direction, the third drive roller 610 rotates in the reverse direction, driving the material strip to move backward. The forward and reverse rotation of the reciprocating drive motor 630 achieves the forward and reverse rotation of the third drive roller 610, thereby driving the material strip to reciprocate below the engraving mechanism 800. The third pressure roller 620 maintains cooperation with the third drive roller 610 throughout the process to ensure effective clamping and transmission of the material strip.

[0042] In some embodiments, refer to Figure 2The output shaft of the reciprocating drive motor 630 is directly connected to the first end of the third drive roller 610. It can be understood that by rigidly connecting the output shaft of the reciprocating drive motor 630 to the first end of the third drive roller 610, intermediate transmission components such as gears and belts are eliminated. When the output shaft of the reciprocating drive motor 630 rotates forward, the first end of the third drive roller 610 rotates synchronously in the forward direction, driving the entire third drive roller 610 to rotate. The third drive roller 610 and the third pressure roller 620 clamp the material belt and convey it forward. When the output shaft of the reciprocating drive motor 630 rotates in the reverse direction, the first end of the third drive roller 610 immediately rotates synchronously in the reverse direction, driving the material belt to move backward. This direct connection avoids angular errors and time delays caused by factors such as gear backlash and belt tension in the transmission chain, ensuring that the rotation angle of the reciprocating drive motor 630 is completely consistent with the rotation angle of the third drive roller 610, thereby achieving control over the material belt's movement distance and position. For example, when making trademark labels that require precise engraving and positioning, the output shaft of the reciprocating drive motor 630 directly drives the first end of the third drive roller 610 to rotate. When the engraving mechanism 800 needs to engrave a fine pattern with a precision of 0.1 mm on the material strip, the third drive roller 610 immediately rotates synchronously with the same angle for every small angle rotated by the reciprocating drive motor 630. The moving distance of the material strip can accurately correspond to the processing requirements of the engraving mechanism 800. Through the precise control of the forward and reverse rotation of the reciprocating drive motor 630, the material strip performs precise reciprocating positioning movement below the engraving mechanism 800, ensuring that the engraved decorative pattern has extremely high dimensional accuracy and positional accuracy.

[0043] In some embodiments, refer to Figure 3 , 4It also includes an intermediate drive shaft 300, which is connected to the third drive roller 610 and is connected to the first drive roller 410 or the second drive roller 510. The first drive roller 410 and the second drive roller 510 are connected by a second belt drive. It is understood that a transmission connection is established between the intermediate drive shaft 300 and the third drive roller 610. When the reciprocating drive motor 630 drives the third drive roller 610 to rotate, the intermediate drive shaft 300 rotates synchronously. The intermediate drive shaft 300 then establishes a transmission connection with either the first drive roller 410 or the second drive roller 510 to transmit power to that drive roller. At the same time, the first drive roller 410 and the second drive roller 510 are connected by a second belt to form a coordinated transmission. When the first drive roller 410 receives power from the intermediate drive shaft 300 and rotates, it drives the second drive roller 510 to rotate synchronously via the second belt. Alternatively, when the second drive roller 510 receives power from the intermediate drive shaft 300 and rotates, it drives the first drive roller 410 to rotate synchronously via the second belt. In this way, the entire transmission system forms a complete power transmission chain from the reciprocating drive motor 630 to the third drive roller 610, then to the intermediate drive shaft 300, and finally to the first drive roller 410 and the second drive roller 510.

[0044] In some embodiments, refer to Figure 2-4 The system also includes a cutter assembly 900, which is positioned between the reciprocating drive mechanism 600 and the engraving head. The cutter assembly 900 is used to cut the printed and engraved strip to obtain the finished product. Understandably, the cutter assembly 900 is installed between the reciprocating drive mechanism 600 and the engraving head. After the strip completes thermal printing on the print head 200, it is conveyed by the second conveying mechanism 500 to the reciprocating drive mechanism 600. The reciprocating drive mechanism 600 drives the strip to reciprocate under the engraving head to complete the engraving process. The strip then continues to move to the cutter assembly 900, where it activates its cutting mechanism to laterally cut the printed and engraved strip, thus separating the continuous strip into independent finished product units. The cut finished product is output from the cutter assembly 900, completing the entire processing flow. The uncut strip portion remains between the reciprocating drive mechanism 600 and the engraving head, awaiting the next processing cycle.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
