The L-shaped spring limit bracket is installed on one side of the fixed support plate by connecting bolts. The printer head mounting bracket of this utility model, through the setting of the L-shaped spring limit bracket, the buffer spring, the upper buffer spring mounting protrusion of the printer head mounting plate, and the limit switch mounting plate, can prevent the printer head from making hard contact and collision with the printing platform during printing.
[0004] However, most existing printheads are fixed in position, and the printing direction is fixed when printing on products. This makes it inconvenient to print on different positions of different products, requiring the replacement of printheads with the corresponding direction, which is time-consuming, labor-intensive, and lacks flexibility and applicability. Therefore, it does not meet the current needs. To address this, we have proposed a printhead angle adjustment structure. Utility Model Content
[0005] The purpose of this utility model is to provide a printhead angle adjustment structure to solve the problems mentioned in the background art, which are that most existing printheads are fixed in position, and the printing direction is fixed when printing on products. This makes it inconvenient to print on different positions of different products, and requires changing the printhead with the corresponding direction, which is time-consuming, labor-intensive, and has low flexibility and applicability.

[0012] Preferably, mounting plates are provided at both ends of the front and rear surfaces of the support base, and the mounting plates are welded and fixed to the support base.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model sets a gear timing belt between two adjacent printhead assemblies, with one mounting slot corresponding to one printhead assembly. The rotating column is inserted into the mounting slot, and the rotating column rotates with the support seat through ball bearings. The output end of the servo motor drives one rotating column to rotate, which drives the gear timing belt to rotate. Then, the gear timing belt drives another gear to rotate, thus realizing transmission. This allows multiple rotating columns to rotate, thereby adjusting the rotation of the printhead seat and realizing the adjustment of the coding angle. It is suitable for different product needs, improving flexibility and applicability. It solves the problem that most existing printheads are fixed in position, and when coding products, the coding direction is fixed, which is inconvenient for coding different positions of different products. It requires changing the printhead with the corresponding direction, which is time-consuming, labor-intensive, and has low flexibility and applicability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1-4This utility model provides an embodiment of a printer nozzle angle adjustment structure, comprising: a support base 1, an mounting groove 3 on the upper surface of the support base 1, the mounting groove 3 extending vertically, and multiple mounting grooves 3 are provided; a nozzle assembly 2 is inserted into the mounting groove 3, with one mounting groove 3 corresponding to one nozzle assembly 2; a gear timing belt 5 is provided between two adjacent nozzle assemblies 2, and multiple gear timing belts 5 are provided; a drive assembly 19 is provided above the support base 1; the nozzle assembly 2 includes a rotating column 12, a gear 13 is provided near the top of the rotating column 12, and the gear 13 meshes with the gear timing belt 5; a ball bearing 4 is provided between the rotating column 12 and the inner wall of the mounting groove 3, and the rotating column 12 is rotatably connected to the support base 1 through the ball bearing 4; the nozzle assembly 2 also includes a connecting sleeve 15, a nozzle seat 14 is provided at the lower end of the connecting sleeve 15, and a feed port 16 is provided on one side surface of the connecting sleeve 15, with one end of the internal channel of the feed port 16 extending through... The drive assembly 19 includes a servo motor 8, the output end of which is provided with a connecting plate 9, and the output end of the servo motor 8 is fixed to the rotating column 12 through the connecting plate 9 with external fasteners. The drive assembly 19 also includes a support frame 7, the top of which is provided with a first bolt 10, and the support frame 7 is threadedly fixed to the servo motor 8 through the first bolt 10. The bottom ends of both sides of the support frame 7 are provided with second bolts 11, and the second bolts 11 pass through the support frame 7 and are threadedly connected to the support base 1. The servo motor 8 is fixed through the support frame 7. One mounting slot 3 corresponds to one nozzle assembly 2.
