Description

Technical Field

[0001] The utility model relates to the field of printers, in particular to a new type of thermal printer.

Background Art

[0002] A thermal printer is a device that uses heat energy for printing. It realizes the printing of text, images or barcodes by controlling the heating of the print head. The following are some common characteristics and uses of thermal printers: Fast speed: Thermal printers usually print at high speed, with a printing speed of dozens to hundreds of millimeters per second. Low noise: Since thermal printers do not require the use of ink or carbon ribbons, there is almost no noise during the printing process. Easy to maintain: Thermal printers usually do not require the replacement of ink cartridges or carbon ribbons, and the maintenance cost is relatively low. Relatively low image quality: Since thermal printers use thermal paper or thermal film, the image quality is relatively low compared to other printing technologies (such as inkjet or laser printing), and it is not suitable for high-demand image printing.

[0003] Currently, for most printers on the market, the rubber roller is installed on the upper shell, and the print head is installed on the lower shell. When the upper shell and the lower shell are closed, the gear on the rubber roller installed on the upper shell is coupled with the gear in the movement installed on the lower shell, so that the rotation of the gear in the movement drives the rubber roller to rotate. Since the gear on the rubber roller is not fixedly coupled with the gear in the movement installed on the lower shell, there will be a coupling error when closing the cover, which affects the printing effect. At the same time, since the heating print head is on the lower shell, users are easily scalded when using it.

[0004] In view of this, overcoming the above-mentioned defects of the existing technology is an urgent problem to be solved in the technical field.

Specific implementation manner

[0044] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0045] Example 1:

[0046] At present, the rubber rollers 311 of most printers on the market are installed on the upper shell 4, and the print head is installed on the lower shell 1. When the upper shell 4 and the lower shell 1 are closed, the gears on the rubber roller 311 installed on the upper shell 4 are coupled with the gears in the movement installed on the lower shell 1, so that the rotation of the gears in the movement drives the rubber roller 311 to rotate. Since the gears on the rubber roller 311 and the gears in the movement installed on the lower shell 1 are not fixedly coupled, there will be a coupling error during the closing and coupling, which will affect the printing effect. At the same time, since the heat-generating print head is on the lower shell 1, users are easily scalded when using it.

[0047] To solve the above problems, this embodiment provides a new type of thermal printer, as Figures 1-12 shown. It includes a lower shell 1, a movement assembly 2, a printing rubber roller assembly 3, an upper shell 4, and a TPH assembly 5;

[0048] The movement assembly 2 is installed on the lower shell 1, and the printing rubber roller assembly 3 is coupled with the movement assembly 2 so that the movement assembly 2 drives the printing rubber roller assembly 3 to rotate;

[0049] The printing rubber roller assembly 3 includes a rubber roller rotating assembly 31 and a bushing 32. The rubber roller rotating assembly 31 includes a rubber roller 311 and a rubber roller gear 312. Among them, the rubber roller 311 is fixedly connected to the rubber roller gear 312. The bushing 32 is sleeved at both ends of the rubber roller 311, and the bushing 32 is fixedly connected to the lower shell 1 for fixing the rubber roller rotating assembly 31 to the lower shell 1. And the sleeving method of the bushing 32 and the rubber roller 311 is a clearance fit, so that the rotation of the rubber roller gear 312 drives the rubber roller 311 to rotate; the movement assembly 2 includes a motor 22 and a plurality of driving gears 21. The rotation of the motor 22 drives the plurality of driving gears 21 to rotate. The driving gears 21 are coupled with the rubber roller gears 312, so that the rotation of the driving gears 21 drives the rotation of the rubber roller gears 312. The rotation of the rubber roller gears 312 drives the rubber roller 311 fixedly connected to the rubber roller gears 312 to rotate, thereby realizing the function of the movement assembly 2 driving the printing rubber roller assembly 3 to rotate.

[0050] The TPH assembly 5 is installed on the upper shell 4. When the upper shell 4 covers the lower shell 1, the TPH assembly 5 is coupled with the printing rubber roller assembly 3 to achieve printing.

[0051] The TPH assembly 5 includes fixing claws 51, a TPH base 52, a TPH substrate 53, a TPH adhesive 54, and a TPH print head 55. Among them, the fixing claws 51 are installed at both ends of the TPH base 52, the TPH substrate 53 is installed at one end of the TPH base 52 close to the fixing claws 51, and the TPH print head 55 is connected to the TPH substrate 53 through the TPH adhesive 54. When the upper shell 4 and the lower shell 1 are closed, the fixing claws 51 are engaged with the bushing 32, so that the TPH print head 55 of the TPH assembly 5 abuts against the rubber roller 311, thereby achieving the printing effect.

[0052] Preferably, the TPH assembly 5 is coupled with the printing rubber roller assembly 3 to achieve printing, specifically including: The TPH assembly 5 includes fixing claws 51;

[0053] The printing rubber roller assembly 3 includes a rubber roller rotating assembly 31 and a bushing 32. The bushing 32 is rotatably sleeved on the rubber roller rotating assembly 31, and the bushing 32 is fixedly connected to the lower shell 1. When the upper shell 4 is closed on the lower shell 1, the fixing claws 51 are engaged with the bushing 32.

[0054] Preferably, the printing rubber roller assembly 3 is coupled with the movement assembly 2, specifically including:

[0055] The rubber roller rotating assembly 31 includes a rubber roller 311 and a rubber roller gear 312, and the rubber roller 311 is fixedly connected to the rubber roller gear 312;

[0056] The rubber roller gear 312 is engaged with the drive gear 21 in the movement assembly 2, so that the drive gear 21 drives the rubber roller gear 312 to rotate, thereby driving the rubber roller 311 to rotate.

[0057] When the TPH assembly 5 is installed on the upper shell 4, there may be an installation error. If there is an installation error in the TPH assembly 5, the fixing claws 51 may not be engaged with the bushing 32 when they are engaged. To solve this technical problem, preferably, the TPH assembly 5 is installed on the upper shell 4, specifically including:

[0058] The TPH assembly 5 includes a TPH base 52. The fixing claws 51 are fixedly connected to the TPH base 52, and the TPH base 52 includes a first convex block 521 and a second convex block 522;

[0059] The upper shell 4 includes a first through hole 41 and a second through hole 42. The first convex block 521 is movably coupled with the first through hole 41, and the second convex block 522 is movably coupled with the second through hole 42.

[0060] When the TPH base 52 is installed with the upper shell 4, the first bump 521 on the TPH base 52 passes through the first through hole 41, and the second bump 522 passes through the second through hole 42. Among them, the first bump 521 and the first through hole 41 are in clearance fit, and the second bump 522 and the second through hole 42 are in clearance fit. In order to make the fixing claw 51 better engage with the bushing 32, the first bump 521 can slide in the first through hole 41, and the second bump 522 can slide in the second through hole 42. When the upper shell 4 and the lower shell 1 are closed, in order to make the fixing claw 51 engage with the bushing 32, the TPH base 52 can move relatively, and the fixing claw 51 adapts to the bushing 32, thereby solving the problem that the fixing claw 51 may not engage with the bushing 32 when engaging.

[0061] When the upper shell 4 and the lower shell 1 are closed, the fixing claw 51 engages with the bushing 32, so that the TPH print head 55 of the TPH assembly 5 abuts against the rubber roller 311. However, in actual scenarios, the TPH print head 55 may not abut tightly against the rubber roller 311. If the TPH print head 55 does not abut tightly against the rubber roller 311, the printing effect will be affected. To solve this technical problem, preferably, the TPH base 52 further includes a first positioning post 523;

[0062] The upper shell 4 further includes a second positioning post 43. The spring 7 is sleeved between the first positioning post 523 and the second positioning post 43, so that when the upper shell 4 is closed on the lower shell 1, the TPH assembly 5 abuts against the rubber roller 311.

[0063] Preferably, the TPH assembly 5 further includes a TPH substrate 53, and the TPH substrate 53 is fixedly connected to the TPH base 52.

[0064] Preferably, the TPH assembly 5 further includes a TPH print head 55 and a TPH back glue 54, and the TPH print head 55 is fixed to the TPH substrate 53 through the TPH back glue 54.

[0065] In actual scenarios, in order to make the fixing claw 51 engage with the bushing 32, the TPH base 52 can slide in the upper shell 4, so as to realize the adaptation of the fixing claw 51 to the bushing 32, so as to solve the problem that the fixing claw 51 may not engage with the bushing 32 when engaging. However, if the TPH base 52 is not limited, the TPH base 52 may fall out of the upper shell 4 during the sliding process. It further includes a baffle 6, and the baffle 6 is fixedly connected to the upper shell 4 and is used to limit the TPH assembly 5.

[0066] Preferably, the limiting of the TPH component 5 is specifically as follows:

[0067] The baffle 6 includes a first limiting platform 61, and the first limiting platform 61 is used to abut against the fixing claw 51, so as to achieve limiting.

[0068] Preferably, the movement mechanism component 2 includes a motor 22, so that when the motor 22 rotates, it drives the printing rubber roller component 3 to rotate.
