Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, in particular to a tube ring printing device. Background Art

[0002] The production and processing of various existing tubes often requires 360-degree circular printing. For example, in the medical device industry, many medical catheters are laser-marked or printed with color rings or scales to facilitate determining the insertion length and positioning of the catheter within the body during use. Anesthesia catheters, for example, have multiple circular markings on their surface, which are used to determine the placement depth of the catheter during use. These markings are typically produced using circular printing technology.

[0003] There are two main types of existing tube ring printing equipment. The first type is a rotary shaft printing device, which usually uses shaft-like parts to install and fix the tube body. The shaft can drive the tube body to rotate. When printing, the relative position of the shaft and the printing rubber head is adjusted to print the ink on the tube body; the second type is a friction rotary printing device, which usually uses a fixed mounting plate to install and fix the tube body. The fixed mounting plate is provided with a buffer groove for the rotation and movement of the tube body. When printing, the friction force of the printing rubber head or an additional drive plate drives the tube body to rotate in the buffer groove, thereby printing the ink on the tube body.

[0004] In the existing printing method, the installation of the tube body usually needs to be a separate process. During the production process, the tube body needs to be manually assembled on a rotating shaft or a fixed mounting plate. The processing steps are cumbersome, the printing interval is long, the production efficiency is low and the production cost is high, which is not suitable for mass production; in addition, when installing the tube body, manual operation is more likely to cause tube body position deviation, especially in the structure using a fixed mounting plate. The tube body is more likely to shift under the influence of a single friction force, resulting in low consistency of the tube body after printing the same batch, affecting the quality of the printed tube body. Summary of the Invention

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, a tube ring printing device includes a body 1, characterized in that the body 1 is provided with a conveying device 2 for transporting the tube to be printed, a transmission device 3 for driving the tube to rotate, a fixing device 4 for fixing and assisting the rotation of the tube, a printing device 5 for printing on the surface of the tube, and a drying device 6 for drying the surface of the tube after printing.

[0031] The conveying device 2 includes an active conveying wheel 201 and a driven conveying wheel 202 respectively arranged at the front and rear ends of the fuselage 1.

[0032] In a specific embodiment, further, a conveying lifting cylinder 203 is provided under the active conveying wheel 201 and the driven conveying wheel 202. The conveying lifting cylinder 203 is used to adjust the height of the active conveying wheel 201 and the driven conveying wheel 202 during the printing process, so that the tube to be printed on the conveyor belt and the transmission device 3 can be lowered to cooperate or raised to separate.

[0033] In a specific embodiment, further, a limiting bar 204 for limiting the conveying of the printed tube body is provided above the conveyor belt at the end of the active conveying wheel 201, that is, after the printing of the tube body is completed, the conveyor belt rises to clamp the tube body between the conveyor belt and the limiting bar 204. The friction and movement of the conveyor belt enable the tube body to roll forward in a rotating manner, so that the tube body is dried more evenly after printing, and at the same time prevents the tube body from shaking and falling off during movement.

[0034] In a specific embodiment, further, the transmission device 3 includes a transmission motor 303, the transmission motor 303 is connected to the active transmission wheel 301 through a belt transmission, and the active transmission wheel 301 is connected to the driven transmission wheel 302 through a belt transmission.

[0035] In a specific embodiment, further, a fixed adjustment structure 304 for adjusting the distance between the driven transmission wheel 302 and the active transmission wheel 301 is provided at the end of the driven transmission wheel 302 .

[0036] Preferably, the fixed adjustment structure 304 may be an adjustment bolt.

[0037] In a specific embodiment, further, the fixing device 4 includes a lifting platform 401 installed on the upper end of the fuselage 1, and the lower end of the lifting platform 401 is connected to a fixed lifting cylinder 402 for controlling small-range lifting, and the fixed lifting cylinder 402 is connected to a fixed wheel 403 that can rotate in coordination with the active transmission wheel 301 and the driven transmission wheel 302.

[0038] In a specific embodiment, further, the edges of the sheet structures of the active transmission wheel 301 , the driven transmission wheel 302 and the fixed wheel 403 are provided with rubber rings for frictionally driving the tube body.

[0039] In a specific embodiment, further, the printing device 5 includes a printing motor 501 and an ink cartridge 503, the printing motor 501 is connected to the printing transmission wheel 502 with a belt transmission, the ink cartridge 503 is provided with an inking wheel 504, the printing transmission wheel 502, the inking wheel 504, and the printing wheel 505 are connected by a belt transmission, and the conveyor belt at the inking wheel 504 takes ink from the ink cartridge 503 and runs to the printing wheel 505, and contacts with the tube body at the printing wheel 505 to complete printing.

[0040] Preferably, the transmission belts between the printing transmission wheel 502, the inking wheel 504, and the printing wheel 505 can be conveyor belts with patterns or texts, so as to be suitable for different printing situations.

[0041] In a specific embodiment, further, the inking wheel 504 and the printing transmission wheel 502 are thin-film structures that can be connected with multiple belt drives. The inking wheel 504 and the printing transmission wheel 502 can be connected to drive multiple printing wheels 505, thereby printing on multiple positions of the tube body.

[0042] In a specific embodiment, further, the drying device 6 includes a plurality of drying fans 601 for drying the surface of the tube body after printing is completed.

[0043] The specific working process of this device is as follows: before the printing process begins, the relative position between the active transmission wheel 301 and the driven transmission wheel 302 is adjusted according to the diameter of the tube to be printed, the lifting range of the fixed wheel 403 is adjusted, and the number and position of the printing wheels 505 are adjusted according to the number and position of the rings to be printed;

[0044] When printing starts, the transport lifting cylinder 203 drives the active transport wheel 201 and the driven transport wheel 202 to rise. The tube is placed on the conveyor belt of the conveyor device 2 by the tube loading device coordinated with the tube printing equipment or manually. The active transport wheel 201 drives the driven transport wheel 202 to rotate, thereby driving the conveyor belt to transport the tube to the conveying device 3.

[0045] When the tube body is transported to the position between the active transmission wheel 301 and the driven transmission wheel 302, the transport lifting cylinder 203 drives the active transmission wheel 201 and the driven transmission wheel 202 to descend, placing the tube body between the transmission wheel 301 and the driven transmission wheel 302. The lifting platform 401 and the fixed lifting cylinder 402 drive the fixed wheel 403 to descend, fixing the tube body in the transmission device 3. The transmission motor 303 drives the active transmission wheel 201 to rotate, the active transmission wheel 201 drives the driven transmission wheel 202 to rotate, and the fixed wheel 403 cooperates with the two transmission wheels to rotate, and the friction of the rubber ring structure on the edge of each wheel sheet structure drives the tube body to rotate; at the same time, the printing motor 501 drives the printing transmission wheel 502 to rotate, and the printing transmission wheel 502 drives the inking wheel 504 and the printing wheel 505 to rotate through the conveyor belt. The conveyor belt at the inking wheel 504 takes ink from the ink cartridge 503 and runs to the printing wheel 505 to print on the rotating tube body, thereby completing the annular printing on the surface of the tube body;

[0046] After the printing process is completed, the fixed wheel rises, and the active conveying wheel 201 and the driven conveying wheel 202 rise to the position where the tube body is clamped with the limit bar 204, thereby driving the tube body to roll forward. During the forward process, it passes through the drying device 6, and the drying fan 601 in the drying device 6 completes the drying of the ink on the surface of the tube body, and moves the printed tube body to the subsequent processing equipment through the matching tube body picking device, and the process of this equipment ends.
