[0002] The working principle of a thermal plotter is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printing paper, the required pattern can be printed. Its principle is similar to that of a thermal fax machine. The image is generated by heating and a chemical reaction in the film. The chemical reaction of this thermal plotter is carried out at a certain temperature. In the existing thermal plotter, its print head assembly includes a mounting plate and a thermal print head fixed on the mounting plate. The mounting plate is mounted on the casing of the thermal plotter. The casing has a limit plate on the side of the mounting plate away from the thermal print head. A spring is provided between the limit plate and the mounting plate. The spring can apply force to the mounting plate so that the thermal print head can be close to the thermal plotter.

[0003] Referring to the existing patent publication number: CN215705135U, a print head assembly mounting structure of a thermal printer includes a housing, a print head assembly and at least one spring; the housing is provided with a limit plate, and the limit plate is provided with a stepped through hole with a small upper part and a large lower part; the print head assembly includes a mounting plate and a thermal print head fixed to the bottom side of the mounting plate; the upper spiral body of the spring is inserted into the stepped through hole and the upper spiral body abuts against the stepped surface of the stepped through hole; the utility model can install the spring from the stepped through hole of the housing, and the entire process of installing the spring is very convenient.

[0004] However, in actual use, the existing print head assembly lacks a certain limit when the paper is transported out of the plotter, and there is no paper guide at the paper output position on both sides of the print head, so that the plotter sometimes has problems of skew and paper jam during use, thereby affecting the paper output quality and being not conducive to the normal use of the plotter. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose a print head assembly for an industrial-grade thermal plotter. The utility model connects and installs the paper guide through a pad, so that the plotter can limit and guide the paper output under the action of the paper guide during operation to avoid deviation, thereby improving the paper output quality, and the paper guide can adjust the horizontal position to improve flexibility and use effect.

[0015] The utility model is further configured such that the horizontal height of the rotating wheel is lower than the horizontal height of the pad.

[0016] The utility model is further arranged that the lower part of the paper guide plate is in close contact with the pad.

[0017] The utility model is further configured such that the paper guides are symmetrically distributed along the longitudinal center line of the pad.

[0018] The utility model is further configured such that the horizontal height of the paper guide is higher than the horizontal height of the print head assembly.

[0019] The beneficial effects of the utility model are as follows: the utility model connects and installs the paper guide through a pad, so that when the plotter is working, the paper output can be guided to a certain extent under the action of the paper guide to avoid deviation, thereby improving the paper output quality, and the paper guide can be adjusted in a horizontal position to improve flexibility and use effect.

[0027] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of this patent, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing this patent and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0030] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0031] Reference Figure 1-4 , a print head assembly of an industrial-grade thermal plotter, comprising: a print head assembly 1, which is detachably connected to the thermal plotter and has a bracket 5 connected to the surface; a pad 2, which is detachably installed on the surface of the bracket 5 through a connection hole 4 opened on the surface, and the pad 2 can be connected and installed with the print head assembly 1 through the connection holes 4 on its surface and tools such as bolts; a paper guide 3, which is movably connected to both sides of the surface of the pad 2, and the plotter can guide and position the paper to a certain extent through the paper guides 3 on both sides during the paper output process to avoid skewed paper clamping, so as to eliminate the phenomenon of poor printing under harsh conditions, thereby improving the printing quality; an adjustment mechanism for driving the paper guide 3 to move horizontally is installed between the pad 2 and the paper guide 3, and the position of the paper guide 3 can be horizontally adjusted through the adjustment mechanism, so that after the horizontal position between the paper guides 3 is adjusted to a certain distance, different specifications of paper can be limitedly guided to improve the usability.

[0032] Specifically, refer to Figure 3-4 The adjusting mechanism includes: a slide groove 6, a screw rod 8, a threaded sleeve 9 and a rotating wheel 7; the slide grooves 6 are all opened on both sides of the surface of the pad 2, the screw rods 8 are all connected to the inside of the slide grooves 6, the rotating wheels 7 are all installed on the surface of the screw rod 8, and the threaded sleeves 9 are all installed on the other side of the surface of the screw rod 8 and connected to the paper guide 3. Through this embodiment, the user can drive the screw rod 8 to rotate by rotating the rotating wheel 7. After the screw 8 rotates, it can drive the threaded sleeve 9 on its surface to move horizontally in the slide groove 6, thereby driving the paper guide 3 to move horizontally through the threaded sleeve 9.

[0033] Furthermore, the rotating wheel 7 and the threaded sleeve 9 are arranged relatively far apart, and the surface of the rotating wheel 7 is constructed with anti-skid grooves. Through this design, the movement of the guide paper 3 can avoid the position of the rotating wheel 7, thereby preventing the guide paper 3 from colliding with the rotating wheel 7 during movement, which makes it difficult for personnel to drive the rotating wheel 7 to rotate, and the anti-skid grooves on its surface can make it more convenient for personnel to operate, thereby increasing friction and avoiding slipping.

[0034] Furthermore, the horizontal height of the rotating wheel 7 is lower than the horizontal height of the pad 2. This design makes it easier for people to rotate the rotating wheel 7, thereby avoiding the situation where the rotating wheel 7 is located in the slide groove 6 and it is difficult to drive the rotating wheel 7 to rotate. In addition, the rotating wheel 7 has a certain operating space and can avoid interfering with the printed paper.

[0035] Furthermore, the lower part of the paper guide paper 3 is in close contact with the pad 2. Through this design, when the screw 8 drives the threaded sleeve 9 to move, the paper guide paper 3 can move horizontally on the surface of the pad 2 relatively smoothly, avoiding the screw 8 driving the threaded sleeve 9 and the paper guide paper 3 to rotate.

[0036] Furthermore, the paper guides 3 are symmetrically distributed along the longitudinal center line of the pad 2. This design allows the paper guides 3 to have a certain degree of coordination and symmetry, thereby preventing the left-right position from being unbalanced and affecting the paper output effect.

[0037] Furthermore, the horizontal height of the paper guide 3 is higher than the horizontal height of the print head assembly 1. Through this design, the height of the paper guide 3 is higher than the print head assembly 1, which can ensure that the medium is correctly guided before entering the print head assembly 1, avoiding collision or friction between the medium and the print head assembly 1, thereby protecting the print head and ensuring printing quality, and can reduce the risk of paper jam or misalignment during the paper feeding process, thereby improving the stability and reliability of the plotter.

[0038] Working principle: When using the utility model, first connect the pad 2 to the print head assembly 1 through the connecting holes 4 on its surface and tools such as bolts, and then paper guides 3 are arranged on both sides of the pad 2, so that the plotter can guide and position the paper to a certain extent through the paper guides 3 on both sides during the paper output process, so as to avoid skewed paper clamping, eliminate the phenomenon of poor printing under harsh conditions, and thus improve the printing quality. During the use of the paper guide 3, the user can drive the screw 8 to rotate through the rotating wheel 7. After the screw 8 rotates, it can drive the threaded sleeve 9 on its surface to move horizontally in the slide groove 6, thereby driving the paper guide 3 to move horizontally through the threaded sleeve 9 to adjust the relative distance between the paper guides 3. After adjustment, papers of different specifications can be positioned and guided, thereby improving flexibility and use effect.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
