[0030] like Figure 1 As shown in the figure, this application provides a cylindrical printing apparatus, which includes a printing head mechanism, a first motion mechanism, and a second motion mechanism.

[0031] The printing head mechanism is used in conjunction with the screen for printing. Since the pattern on the surface of the cylindrical product may be printed along a straight line or along a curve, the printing head mechanism achieves horizontal movement along any path through the first and second motion mechanisms, thereby meeting the printing requirements of the cylindrical product.

[0032] In some examples, such as Figure 1 , Figure 2 and Figure 3 As shown, the print head mechanism is disposed on the first motion mechanism, and the print head mechanism is movable relative to the first motion mechanism. Specifically, the print head mechanism performs linear motion relative to the first motion mechanism, thereby enabling the print head mechanism to achieve the first degree of freedom of motion.

[0033] In some examples, the first motion mechanism includes a first slide rail 101, and the print head mechanism includes a mounting component, which is mounted on the first slide rail 101. Wherein, the mounting component is slidably connected to the first slide rail 101, allowing the print head mechanism to move along the first slide rail 101.

[0034] Specifically, the first slide rail 101 extends in the horizontal direction, meaning that the first degree of freedom of the printing head mechanism is the horizontal movement degree of freedom.

[0035] In some examples, such as Figure 1 , Figure 2 and Figure 3 As shown, the first motion mechanism is disposed on the second motion mechanism, and the first motion mechanism is movable relative to the second motion mechanism. Specifically, the first motion mechanism performs linear motion on the second motion mechanism, and drives the printing head mechanism to perform corresponding motion, thereby enabling the printing head mechanism to achieve a second degree of freedom of motion.

[0036] The direction of movement of the printing head mechanism relative to the first motion mechanism is at an angle to the direction of movement of the first motion mechanism relative to the second motion mechanism, that is, the direction of movement of the first degree of freedom is at an angle to the direction of movement of the second degree of freedom.

[0037] Specifically, the two horizontal degrees of freedom of the printing head mechanism exist simultaneously. Under the superposition of the two, the printing head mechanism can achieve movement along any path in the horizontal direction, thus meeting the printing needs of cylindrical products.

[0038] In some examples, the second motion mechanism includes a nut component and a lead screw 201, with the nut component meshing with the lead screw 201. The nut component forms an integral part with the first motion mechanism; as the lead screw 201 rotates, the nut component drives the first motion mechanism to move along the lead screw 201, thereby realizing the second degree of freedom of the printhead mechanism.

[0039] Furthermore, the lead screw 201 extends horizontally, and to ensure that the direction of movement of the first degree of freedom is at an angle to the direction of movement of the second degree of freedom, the extension direction of the lead screw 201 is at an angle to the extension direction of the first slide rail 101.

[0040] Specifically, the extension direction of the lead screw 201 is perpendicular to the extension direction of the first slide rail 101.

[0041] In some examples, such as Figure 1 As shown, the printing head mechanism includes a printing head body 301, which is used to cooperate with the screen for printing.

[0042] The mounting component is generally plate-shaped, and the printing head mechanism includes a second slide rail 302 disposed on the mounting component. The printing head body 301 is slidably connected to the second slide rail 302 via a lifting assembly 303. Specifically, the second slide rail 302 extends vertically, and the lifting assembly 303 drives the printing head body 301 to move along the second slide rail 302 to adjust the height of the printing head body 301.

[0043] Furthermore, the lifting assembly 303 includes a connecting component and a printing head mounting base that are connected to each other. The connecting component is slidably connected to the second slide rail 302, and a screw and nut mechanism and a corresponding driver are provided between the connecting component and the mounting component. The driver here drives the connecting component to move along the second slide rail 302 through the screw and nut mechanism.

[0044] In some examples, the printhead body 301 is movably mounted on the lifting assembly 303. Specifically, the printhead body 301 is mounted on a printhead mounting base, which drives the printhead body 301 to adjust its height.

[0045] The printhead mounting base includes a guide hole, a guide rod, and a corresponding actuator. The guide rod and guide hole extend vertically, with the guide rod passing through the guide hole and connecting to the printhead body 301. The actuator here drives the guide rod to move vertically along the guide hole, thereby adjusting the height of the printhead body 301.

[0046] Understandably, the connecting component moves along the second slide rail 302 to initially adjust the height of the print head body 301; the guide rod then drives the print head body 301 to move, thereby precisely adjusting the height of the print head body 301.

[0047] In some examples, such as Figure 1 , Figure 2 and Figure 3 As shown, the cylindrical printing apparatus also includes a frame 401 and a support component 402. The frame 401 is fixed in position, the second motion mechanism is connected to the frame 401, and the first motion mechanism is connected to the support component 402.

[0048] The lead screw 201 is rotatably mounted on the frame 401. The support component 402 is connected to the nut component as a whole. The lead screw 201 rotates under the drive of the corresponding driver, thereby causing the nut component to drive the support component 402 to move along the lead screw 201.

[0049] Furthermore, as the support component 402 moves, the first slide rail 101 also moves, thereby driving the printing head body 301 to move.

[0050] In some examples, frame 401 is provided with a screen mounting assembly, the height of which is less than the height of the print head mechanism, and is used to mount the screen.

[0051] During the screen printing process, the screen is first placed over the cylindrical product to facilitate printing by the printing head body 301 through the screen.

[0052] In some examples, the wire mesh mounting assembly includes wire mesh mounting rods 502 located on opposite sides of the frame 401, which facilitate the connection of the wire mesh to the opposite sides of the wire mesh.

[0053] Furthermore, the wire mesh mounting rod 502 extends horizontally to ensure the wire mesh is in a horizontal position. Specifically, the wire mesh mounting rod 502 is approximately perpendicular to the first slide rail 101 and approximately parallel to the wire rod 201.

[0054] In some examples, the frame 401 is provided with a detachable support rod 501. Specifically, the frame 401 is provided with a structure for mounting the support rod 501, so that the support rod 501 can be inserted into the frame 401.

[0055] Furthermore, the support rod 501 is approximately parallel to the first slide rail 101, and each wire mesh mounting rod 502 is connected to the support rod 501 in a clamping manner.

[0056] In actual implementation, a screen is installed on the screen mounting rod 502, so that the screen covers the cylindrical product; under the action of the lifting component 303, the printing head body 301 adjusts its height until the printing head body 301 contacts the screen; the printing head body 301 achieves the first degree of freedom of movement through the first motion mechanism and the second degree of freedom of movement through the second motion mechanism. Since the direction of movement of the first degree of freedom is at an angle to the direction of movement of the second degree of freedom, the printing head body 301 can perform linear printing and curved printing under the combined action of the first motion mechanism and the second motion mechanism, thereby meeting the printing needs of cylindrical products.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
