Description

Technical Field

[0001] The utility model relates to the technical field of barcode printers, in particular to a position sensing component and a barcode printer. Background Art

[0002] Barcode printers are based on heat and use carbon ribbons or thermal paper as printing media to complete printing. The content printed by barcode printers is generally packaging labels, barcode labels, clothing hangtags, bedding labels, etc. When a barcode printer is in use, it is necessary to sense the moving position of the printing medium through a sensor to ensure that the barcode printer can accurately print the barcode on the printing medium.

[0003] In the related art, in order to adapt to the widths of different printing media, the sensor can move in a U-shaped channel on the barcode printer. The sensor has a transmitting end and a receiving end, and the transmitting end and the output end are respectively located on both sides of the U-shaped channel. The printing medium is threaded between the transmitting end and the receiving end. Since there is a gap between two juxtaposed printing media, when the printing medium moves to align with the gap and the sensor, the signal from the transmitting end can pass through the gap and reach the receiving end. Thus, the receiving end transmits the sensing signal to the controller, and the controller controls the printing medium to stop moving, so that the sensor achieves the effect of controlling the moving position of the printing medium.

[0004] However, during the long-term operation of the barcode printer, debris is likely to adhere between the transmitting end and the receiving end of the sensor, and the U-shaped channel is integrally formed, resulting in difficulty in cleaning the debris. Summary of the Utility Model

[0026] The following further elaborates on this application Figures 1-5 in detail with reference to the attached drawings.

[0027] A position sensing assembly proposed in an embodiment of the first aspect of the present utility model, referring to Figure 1 and Figure 2 , includes a first housing 100 and a second housing 200, and the second housing 200 is rotatably connected to the first housing 100. Specifically, one end of the first housing 100 is provided with a hinge seat 110, and one end of the second housing 200 is provided with a hinge head 210. The hinge head 210 is hinged with the hinge seat 110 so that the first housing 100 can swing relative to the second housing 200, and further, the first housing 100 and the second housing 200 have a closed state and an open state. In the closed state, the first housing 100 and the second housing 200 are close to each other, and a first channel 600 for the printing medium to pass through is formed between the first housing 100 and the second housing 200; in the open state, the first housing 100 and the second housing 200 are away from each other.

[0028] It can be understood that in some embodiments of the first aspect of the present utility model, referring to Figure 3 and Figure 4, the position sensing component includes a sensor 300, which is movably arranged in the first channel 600 and can sense the moving position of the printing medium. Specifically, the sensor 300 includes a transmitting part 310 and a receiving part 320. The transmitting part 310 is movably arranged in the first housing 100, and the receiving part 320 is movably arranged in the second housing 200. In the closed state, the position of the transmitting part 310 corresponds to the position of the receiving part 320. And in this embodiment, since there is a gap between two juxtaposed printing media, when the printing medium moves to align with the sensor 300 at the gap, the signal emitted by the transmitting part 310 can pass through the gap and reach the receiving part 320. Thus, the receiving part 320 transmits the sensing signal to the controller, and the controller controls the printing medium to stop moving relative to the sensor 300, so that the sensor 300 achieves the effect of controlling the moving position of the printing medium. At the same time, when the first channel 600 continuously passes through the printing medium, a large amount of debris will adhere to the first channel 600, thus affecting the sensing effect of the sensor 300. At this time, the first housing 100 can be swung relative to the second housing 200 by rotating the hinge head 210 relative to the hinge seat 110, so that the first housing 100 and the second housing 200 are in an open state, facilitating the user to clean the debris in the first chute 120 and the second chute 220, thereby reducing the influence of the debris on the sensing of the sensor 300.

[0029] It can be understood that in some embodiments of the first aspect of the present invention, with reference to Figure 3 and Figure 4 , the first housing 100 is provided with a first chute 120, which is opened along the length direction of the first housing 100, and the transmitting part 310 is slidably engaged with the first chute 120. The second housing 200 is provided with a second chute 220, which is opened along the length direction of the second housing 200, and the receiving part 320 is slidably engaged with the second chute 220. Thus, according to the different sizes of the printing medium when printing different items, the sensor 300 needs to adjust its position accordingly according to the size of the printing medium. By sliding the transmitting part 310 along the first chute 120 and the receiving part 320 along the second chute 220, the overall movement of the sensor 300 is realized, and the position of the transmitting part 310 is kept corresponding to the position of the receiving part 320.

[0030] It can be understood that in some embodiments of the first aspect of the present invention, with reference to Figure 3 and Figure 4, the position sensing component includes a transmission component. When the sensor 300 moves in the first channel 600, the transmission component can keep the transmitting part 310 and the receiving part 320 in alignment. Specifically, the transmission component includes a first gear member, a linkage gear 420, and a second gear member. The first gear member is located in the first housing 100, the linkage gear 420 is rotatably arranged in the hinge seat 110, the second gear member is located in the second housing 200. The movement of the transmitting part 310 along the first chute 120 can cause the first gear member to drive the linkage gear 420 to rotate, and the rotation of the linkage gear 420 can cause the second gear member to drive the receiving part 320 to move. When it is necessary to move the sensor 300, by driving the transmitting part 310 to move relative to the first chute 120, the first gear member is caused to drive the linkage gear 420 to rotate, so that the second gear member can drive the receiving part 320 to move relative to the second chute 220, so that the position of the transmitting part 310 corresponds to the position of the receiving part 320.

[0031] It can be understood that in some embodiments of the first aspect of the present utility model, referring to Figure 3 and Figure 4 , the first gear member includes a first gear 411, a second gear 412, and a first belt 413. The first gear 411 and the second gear 412 are respectively arranged at both ends of the first housing 100. The first belt 413 is respectively engaged with the first gear 411 and the second gear 412. The transmitting part 310 is fixedly arranged on the first belt 413. The first gear 411 is engaged with the linkage gear 420. By driving the transmitting part 310 to move relative to the first chute 120, the first belt 413 rotates relative to the first housing 100, and then the first belt 413 drives the first gear 411 and the second gear 412 to rotate, so that the linkage gear 420 rotates.

[0032] It can be understood that in some embodiments of the first aspect of the present utility model, referring to Figure 3 and Figure 4 , the second gear member includes a third gear 431, a fourth gear 432, and a second belt 433. The third gear 431 and the fourth gear 432 are respectively arranged at both ends of the first housing 100. The second belt 433 is respectively engaged with the third gear 431 and the fourth gear 432. The receiving part 320 is fixedly arranged on the second belt 433. The third gear 431 is engaged with the linkage gear 420. When the linkage gear 420 rotates, it drives the third gear 431 to rotate, so that the second belt 433 rotates relative to the second housing 200 to drive the receiving part 320 to move relative to the second chute 220, achieving the effect that the position of the transmitting part 310 corresponds to the position of the receiving part 320.

[0033] It can be understood that in some other embodiments, a perforation is provided at one end of the first housing 100 away from the hinge seat 110, and a threaded hole is provided at one end of the second housing 200 away from the hinge head 210. A bolt is inserted through the perforation, and one end of the bolt can pass through the perforation and be in threaded engagement with the threaded hole, so that the first housing 100 and the second housing 200 are kept in a closed state, thereby reducing the situation that the first housing 100 and the second housing 200 are accidentally opened when the position sensing assembly is operating.

[0034] The implementation principle of the first aspect embodiment of the present utility model is as follows: when it is necessary to clean the debris in the first channel 600, the hinge head 210 rotates relative to the hinge seat 110, so that the first housing 100 swings relative to the second housing 200, so that the first housing 100 and the second housing 200 are in an open state, so that it is convenient for the user to clean the debris in the first chute 120 and the second chute 220, so as to reduce the influence of the debris on the induction of the sensor 300.

[0035] When the sensor 300 needs to adjust its position according to the size of the printing medium, by driving the transmitting part 310 to move relative to the first chute 120, the first belt 413 rotates relative to the first housing 100, and then the first belt 413 drives the first gear 411 and the second gear 412 to rotate, so that the linkage gear 420 rotates, and then drives the third gear 431 to rotate, so that the second belt 433 rotates relative to the second housing 200, so as to drive the receiving part 320 to move relative to the second chute 220, achieving the effect that the positions of the transmitting part 310 and the receiving part 320 are kept corresponding.

[0037] Specifically, referring to Figure 3 and Figure 5 , the second housing 200 is fixed to the bar code printer 500 through a fastening bolt, so as to fix the position sensing assembly on the bar code printer 500. When it is necessary to clean the first channel 600, the first housing 100 is rotated relative to the second housing 200 so that the two are in an open state, and the debris in the first chute 120 and the second chute 220 can be cleaned, so as to reduce the influence of the debris on the induction of the sensor 300.

[0038] It can be understood that in some embodiments of the second aspect of the present utility model, referring to Figure 5, the barcode printer 500 further includes a limiting mechanism 510 and a rubber roller mechanism 520. After the printing medium passes through the sensor 300, the limiting mechanism 510 is used to guide the moving path of the printing medium, reduce the situation of the printing medium shifting, so as to reduce the influence on the sensing effect of the sensor 300. The printing medium passing through the limiting mechanism 510 is conveyed through the rubber roller mechanism 520. The rubber roller mechanism 520 can help the printing medium maintain flatness during the transmission process through the rubber material, so as to ensure the normal transmission of the printing medium.
