Description

Technical Field

[0001] The utility model relates to the technical field of coding machines, in particular to a thermal coding machine. Background Art

[0002] During the production and sales process, product labeling is often necessary. Different products require different coding information on the labels. The traditional approach is to first print all the information on the labels and then label them with information such as the product or price. This is very inconvenient. If the label coding information is incorrect, all labels may need to be reprinted, which is time-consuming and labor-intensive, affecting work efficiency. Existing coding machines adjust the printed information using a gear train. During adjustment, the adjustment block adjusts the information to be adjusted one by one to output the correct information. This makes the coding machine very cumbersome to adjust, difficult to operate, and inefficient.

[0003] Handheld printers are a common type of coding equipment, widely used in packaging, labeling, anti-counterfeiting, and other fields. They are categorized as impact and non-impact printers, depending on whether the printing element strikes the paper. Based on the technology used, they are classified into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and LED types. Thermal printers are typically used with thermal roll paper, which consists of a heat-sensitive face paper (self-adhesive) and a backing paper. Existing printers leave the face paper and backing paper bonded after printing, making it difficult to remove the face paper, which affects efficiency. Utility Model Content

DETAILED DESCRIPTION

[0030] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0031] Depend on Figure 1 Combine Figure 2-Figure 5 As shown, a thermal coding machine includes a housing 1,

[0032] The coding module 2 is arranged in the housing 1 and is used to code the roll paper 8. The coding module 2 includes a coding element, a coding inlet 21, a coding outlet 22, and a coding terminal for coding the roll paper. The coding element is used to drive the roll paper from the coding inlet 21 into the coding terminal, complete the coding, and then be sent out from the coding outlet 22. The coding module can be implemented using an existing thermal coding module.

[0033] The separation mechanism 3 is provided on the housing 1, behind the coding outlet 22, and is used to separate the top paper portion 81 and the bottom paper portion 82 of the roll paper 8 delivered from the coding outlet 22;

[0034] The traction roller 4 is provided on the housing 1 and is used to pull the bottom paper portion of the roll paper forward;

[0035] A pulling element 5 is disposed within the housing 1; it is connected to the pulling roller 4 and is used to drive the pulling roller 4 to rotate; the pulling element 5 operates synchronously with the coding element. The beneficial effects of this utility model include the provision of a pulling element that pulls the bottom paper portion forward, and the synchronized movement of the pulling element and the coding element. This product exhibits excellent synchronization, facilitates continuous and reliable feeding, and facilitates waste paper recycling. The provision of a separation mechanism separates the top paper portion from the bottom paper portion, facilitating removal of the bottom paper portion and improving efficiency. This utility model also has the advantages of a simple structure, easy assembly, reliable operation, and a long service life.

[0036] The housing 1 is provided with a mounting plate 6, and the pulling roller 4 is positioned above the mounting plate 6. The pulling roller 4 and the mounting plate 6 cooperate to form a pulling channel for the bottom paper to pass through. This structure facilitates the discharge of the bottom paper, and the synchronization of the coding element and the pulling element is good, preventing printing displacement.

[0037] The traction roller 4 is mounted on a traction housing 41, and the traction element 5 is mounted within the traction housing 41. The traction housing 41 is mounted above the mounting plate 6. A traction notch 411 is provided on the traction housing 41 on the side facing the mounting plate 6. The mounting plate 6 is hinged to the housing 1 and can rotate relative to the housing 1. Specifically, one end of the mounting plate is provided with an operating notch for opening the mounting plate. Specifically, one end of the mounting plate is provided with a latching portion for facilitating tearing off the bottom paper. This facilitates the discharge of the bottom paper portion and reliably limits the discharge of the bottom paper portion. Specifically, the present invention further includes a guide block 61 mounted on the mounting plate 6. The guide block 61 is positioned below the traction roller 4. The traction roller 4 and the guide block 61 cooperate with each other to form a traction channel for the bottom paper portion to pass through. More specifically, it also includes an elastic member 62. The guide block 61 is installed from the bottom of the mounting plate 6 and is vertically restrained by the mounting plate 6. The mounting plate 6 is provided with a mounting hole 63 for the guide block 61 to protrude. The elastic member 62 abuts against the guide block 61 and has a tendency to drive the guide block 61 toward the pulling roller 4. This structure ensures a reliable fit between the pulling roller and the guide block, reliably pulling the bottom paper. The provision of the elastic member ensures a reliable fit between the pulling roller and the guide block, and is adaptable to the operation of paper rolls of varying thicknesses.

[0038] The mounting plate 6 and guide block 61 are positioned obliquely toward the side of the pulling roller 4. The pulling element 5 drives the pulling roller 4 via the gear assembly 51. The pulling roller 4 is covered with a rubber sleeve 42. This facilitates the pulling roller's traction and ensures reliable product traction. The rubber sleeve increases friction, ensuring reliable movement of the bottom paper.

[0039] The separation mechanism 3 includes a separation shaft 31 and a separation plate 32 that bends the paper roll's path. When the paper roll is delivered from the coding outlet 22, it passes between the separation shaft 31 and the separation plate 32, separating the top paper portion from the bottom paper portion. Specifically, the separation shaft 31 is provided with a separation sleeve 311, which is equipped with separation protrusions 312 for increasing friction. Multiple separation protrusions 312 are circumferentially arranged on the separation shaft 31. The separation sleeve 311 is integrally molded from a rubber material. This structure separates the top paper portion from the bottom paper portion, making it easier for staff to quickly remove the top paper portion and improving work efficiency.
