Technical Field
[0001] This utility model relates to the field of UV printing technology, and more specifically, to a UV positioning printing fixture device for single parts. Background Technology
[0002] UV printing is a digital printing technology that uses ultraviolet (UV) light to instantly cure ink. Its core principle is that the printhead sprays UV-specific ink onto the substrate surface, while a UV lamp rapidly cures the ink, preventing smudging or seepage. Its key advantages include a wide range of substrates, adaptable to various materials such as glass, metal, stone, plastic, wood, and ceramics, without requiring pretreatment. It also features instant drying, vibrant and saturated colors, strong adhesion, and scratch resistance. Furthermore, it can achieve special effects such as embossing and varnishing, and can print on both flat and simple curved surfaces like cylinders. This technology is widely used in advertising signage, decorative building materials, personalized customization (such as phone cases and mugs), and packaging printing, suitable for both small-batch personalized orders and medium-scale production needs, making it one of the mainstream technologies in the digital printing field in recent years.
[0003] Currently, during the printing process of individual cylindrical parts, these parts are prone to rolling, and often need to be rotated at a certain angle to change different printing surfaces. However, this rotation can easily cause forward or backward displacement, leading to print pattern shifts and misalignments, thus affecting print quality. In view of this, we propose a UV positioning printing fixture for individual cylindrical parts. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a UV positioning printing fixture device for single loose parts, so as to solve the technical problem that it is inconvenient to print cylindrical loose parts.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a single component UV positioning printing fixture device, including a printer body and a positioning adjustment mechanism provided on the printer body. The printer body includes a frame platform, and the top surface of the frame platform is provided with a table surface in the middle. The positioning adjustment mechanism includes a base plate provided on the top surface of the frame platform. The base plate is connected to the frame platform by bolts. The top of the base plate is symmetrically provided with a first mounting plate. The first mounting plate is symmetrically provided with mounting grooves. Support wheels are rotatably installed in the mounting grooves. The positioning adjustment mechanism also includes a symmetrically provided fixing plate and a positioning plate provided on the fixing plate.
[0006] Preferably, a second mounting plate is symmetrically arranged on the outer side of the first mounting plate at the top of the base plate, an electric push rod is arranged on the front of the second mounting plate, a mounting plate is arranged at the end of the piston rod of the electric push rod, and a fixing plate is symmetrically arranged on the outer surface of the mounting plate.
[0007] Preferably, the included angle between the two fixing plates is 90 degrees, the fixing plates are L-shaped, and the fixing plates are gradually expanded outward along the long axis.
[0008] Preferably, a spring is provided on the bottom surface of the fixing plate, and the positioning plate is installed at the end of the spring. The positioning plate includes a plurality of positioning parts and a plurality of bent parts along the long axis direction. The bent parts are connected between the positioning parts. The positioning parts are horizontally arranged, and the bent parts are inclined outward. The plurality of positioning parts and the plurality of bent parts form a stepped shape for the positioning plate. The working surface of the positioning part is provided with ball bearings.
[0009] Preferably, the printer body further includes a first lead screw disposed within the frame platform, a movable beam disposed on the first lead screw, and a second lead screw disposed within the movable beam. The movable beam is equipped with a liftable lifting frame via the second lead screw, and a print head is mounted on the front of the lifting frame.
[0010] Preferably, a driven gear connected to the shaft of the support wheel is rotatably mounted on the back of the first mounting plate, and a connecting gear meshing with the driven gear is also provided on the back of the first mounting plate. A driving gear meshing with the connecting gear is rotatably mounted at the center of the back of the first mounting plate. A third mounting plate is provided on the back of the first mounting plate, and a drive motor for driving the driving gear is provided on the third mounting plate. A connecting shaft connected to the shaft of the driving gear is provided between the two first mounting plates, and the connecting shaft connects the two driving gears.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model designs a support wheel and positioning plate structure, forming a dual positioning system of "upper and lower clamping + side limiting". The support wheel provides a stable support foundation for the cylindrical parts, while the positioning plate, under the elastic action of the spring, tightly fits the surface of the parts, avoiding damage to the parts caused by rigid contact. Secondly, the positioning plate is stepped along the long axis, which can adapt to parts of different diameters through the stepped positioning part, ensuring that the parts do not roll laterally or shift longitudinally during printing. Then, using the transmission chain design of "drive motor - driving gear - connecting gear - driven gear - support wheel", the two support wheels on both sides are rotated synchronously with the connecting shaft, driving the cylindrical parts to rotate smoothly and switch printing surfaces. At the same time, the ball bearings on the working surface of the positioning plate reduce the friction of the parts during rotation, ensuring that the parts are always within the positioning range during rotation, avoiding positional deviation caused by asynchronous rotation or frictional resistance, ensuring accurate connection of multi-sided printed patterns, and solving the problem that it is currently inconvenient to print cylindrical parts.
[0013] 2. This utility model also designs an electric push rod and a fixed plate structure. The electric push rod can drive the fixed plate to move horizontally. Combined with the fixed plate's "L-shaped + long axis outward expansion" structure, it can guide the parts to quickly enter the positioning area. With the help of springs, the spacing between the positioning plates can be flexibly adjusted according to the diameter of the parts. With the help of the stepped positioning part, the device can adapt to cylindrical parts of different diameters. There is no need to change the fixture separately for a single specification of part, which greatly improves the equipment's adaptability to cylindrical products of multiple specifications and further expands the scope of application of the equipment.

Detailed Implementation
[0021] like Figures 1 to 6As shown, this utility model relates to a single component UV positioning printing fixture device, including a printer body 100 and a positioning adjustment mechanism 200 provided on the printer body 100. The printer body 100 includes a frame platform 101, with a table surface in the middle of the top surface of the frame platform 101. The positioning adjustment mechanism 200 includes a base plate 201 provided on the top surface of the frame platform 101. The base plate 201 is connected to the frame platform 101 by bolts. A first mounting plate 202 is symmetrically provided at the top of the base plate 201. The first mounting plate 202 has symmetrically opened mounting grooves 2021. A support wheel 208 is rotatably installed in the mounting groove 2021. The positioning adjustment mechanism 200 also includes a symmetrically arranged fixing plate 205 and a positioning plate 206 provided on the fixing plate 205. This utility model uses a support wheel 208 and a positioning plate 206 to form a dual positioning system to prevent the rolling displacement of loose parts; a spring 207 and a stepped positioning plate 206 are adapted to loose parts of different diameters; a drive motor 213 and other components drive the loose parts to rotate smoothly for surface changing; and the ball bearing 2063 reduces friction to ensure accuracy, thereby improving printing quality and equipment compatibility.
[0022] Specifically, a second mounting plate 203 is symmetrically arranged on the outer side of the first mounting plate 202 at the top of the base plate 201. An electric push rod 204 is arranged on the front of the second mounting plate 203, and a mounting plate 215 is arranged at the end of the piston rod of the electric push rod 204. A fixing plate 205 is symmetrically arranged on the outer surface of the mounting plate 215. The outer mounting position of the second mounting plate 203 can avoid interference with components such as the support wheel 208 on the first mounting plate 202, ensuring that each structure works independently. The electric push rod 204, as a power component, can drive the mounting plate 215 and the fixing plate 205 to move synchronously through the extension and retraction of the piston rod. This allows the spacing of the fixing plates 205 to be adjusted according to the diameter of the cylindrical parts, achieving positioning and adaptation for cylindrical parts of different sizes. The symmetrical arrangement of the fixing plates 205 on the mounting plate 215 ensures sufficient limiting ability for the cylindrical parts, preventing the parts from shifting during the positioning process.
[0023] Furthermore, the included angle between the two fixing plates 205 is 90 degrees, and the shape of the fixing plates 205 is L-shaped, gradually expanding outward along the long axis. The 90-degree included angle allows the area between the two fixing plates 205 to form the area where the print head 105 can move, facilitating the movement of the print head 105 within the included angle between the fixing plates 205. The outward expansion design along the long axis can guide the positioning of cylindrical parts, facilitating the rapid entry of the positioning plate 206 into the positioning area.
[0024] It is worth noting that a spring 207 is provided on the bottom surface of the fixing plate 205, and a positioning plate 206 is installed at the end of the spring 207. The positioning plate 206 includes a number of positioning parts 2061 and a number of bent parts 2062 along the long axis. The bent parts 2062 are connected between the positioning parts 2061. The positioning parts 2061 are horizontally arranged, and the bent parts 2062 are inclined outward. The number of positioning parts 2061 and the number of bent parts 2062 form a stepped shape for the positioning plate 206. The working surface of the positioning part 2061 is provided with ball bearings 2063. Spring 207 has an elastic buffering effect. When the positioning plate 206 contacts the cylindrical part, spring 207 can adaptively compress according to the diameter of the part, so that the positioning plate 206 can fit the surface of the part, while avoiding rigid contact that may cause indentation or damage to the surface of the part. The stepped positioning plate 206, through the alternating arrangement of positioning part 2061 and bending part 2062, can further guide the part into the correct positioning position. With the positioning part 2061 in different positions, cylindrical parts of different diameters can be positioned and pressed. The cylindrical part can be positioned on the support wheel 208. The pressure of spring 207 ensures that there is sufficient friction between the cylindrical part and the support wheel 208. When the support wheel 208 rotates, it is convenient to flip the cylindrical part at different angles, which is convenient for printing at different positions and prevents misalignment.
[0025] It is worth mentioning that the printer body 100 also includes a first lead screw 102 set in the frame platform 101, a moving beam 103 set on the first lead screw 102, and a second lead screw set in the moving beam 103. The moving beam 103 is equipped with a liftable lifting frame 104 via the second lead screw, and the print head 105 is installed on the front of the lifting frame 104. The first lead screw 102 can rotate to drive the moving beam 103 to move along the length of the frame platform 101, thereby driving the print head 105 to adjust its horizontal position to meet the printing needs of cylindrical parts of different lengths. The second lead screw cooperates with the moving beam 103 to drive the lifting frame 104 to move up and down, thereby adjusting the vertical distance between the print head 105 and the cylindrical part, ensuring that the print head 105 is at the optimal printing height and guaranteeing the clarity and accuracy of the printed pattern. The print head 105 is installed on the front of the lifting frame 104, and its position can be flexibly changed with the adjustment of the moving beam 103 and the lifting frame 104 to realize printing operations on different areas of the cylindrical part.
[0026] It is worth noting that a driven gear 211 connected to the axis of the support wheel 208 is rotatably mounted on the back of the first mounting plate 202. A connecting gear 210 meshing with the driven gear 211 is also provided on the back of the first mounting plate 202. A driving gear 209 meshing with the connecting gear 210 is rotatably mounted at the center of the back of the first mounting plate 202. A third mounting plate 212 is provided on the back of the first mounting plate 202. A drive motor 213 for driving the driving gear 209 is provided on the third mounting plate 212. A connecting shaft 214 connected to the axis of the driving gear 209 is provided between the two first mounting plates 202. The connecting shaft 214 connects the two driving gears 209. Driven gear 211 is connected to the shaft of support wheel 208, which can directly transmit the power of gear transmission to support wheel 208, causing support wheel 208 to rotate; the linkage gear 210 can realize the power transmission between drive gear 209 and driven gear 211, and at the same time adjust the transmission ratio to ensure that support wheel 208 obtains a suitable speed; drive gear 209, as a power input component, rotates under the drive motor 213, providing power to the entire gear transmission system; the third mounting plate 212 provides a stable mounting platform for drive motor 213, preventing motor shaking during operation from affecting transmission accuracy; connecting shaft 214 connects the drive gears 209 on the two first mounting plates 202, which can ensure that the two drive gears 209 rotate synchronously, which can facilitate the flipping angle of cylindrical parts and facilitate printing work at different positions.
[0027] Working Principle: This embodiment provides a single-part UV positioning printing fixture device. In use, the cylindrical part to be printed is first placed between the support wheels 208 on the first mounting plate 202 at the top of the base plate 201 in the positioning adjustment mechanism 200. The four symmetrically arranged support wheels 208 provide initial support for the cylindrical part, ensuring it is within the approximate printing area. Next, the electric push rod 204 on the second mounting plate 203 is activated. The piston rod of the electric push rod 204 extends, driving the end mounting plate 215 and the L-shaped fixing plates 205 symmetrically arranged on the outer surface of the mounting plate 215 to move towards the cylindrical part. As the fixing plates 205 gradually expand outward along their long axis, they guide the cylindrical part during movement, causing the positioning plate 206 at the end of the spring 207 on the bottom surface of the fixing plate 205 to gradually approach the part. The positioning parts 2061, distributed in a stepped shape on the positioning plate 206, are positioned by the spring 207. Under the elastic action of spring 7, the spring 207 will adaptively compress according to the diameter of the part, ensuring that the positioning part 2061 fits tightly against the part for accurate positioning, while avoiding damage to the surface of the part caused by rigid contact. At the same time, the ball bearings 2063 on the working surface of the positioning part 2061 can reduce the friction between the part and the positioning plate 206 when the part rotates. At this time, the cylindrical part is stably restricted between the support wheel 208 and the positioning plate 206, preventing it from rolling or shifting during the printing process. Then, according to the printing requirements, the first lead screw 102 in the frame table 101 in the printer body 100 drives the moving beam 103 to move along the length of the frame table 101, adjusting the horizontal position of the moving beam 103. At the same time, the second lead screw in the moving beam 103 drives the lifting frame 104 to move up and down, adjusting the print head 105 on the front of the lifting frame 104 to the optimal printing height and horizontal position that matches the surface of the cylindrical part.When different sides of the cylindrical component need to be printed, the drive motor 213 on the third mounting plate 212 on the back of the first mounting plate 202 is activated. The drive motor 213 drives the connected drive gear 209 to rotate. Since the two first mounting plates 202 are connected to the drive gear 209 by the connecting shaft 214, the two drive gears 209 rotate synchronously. The drive gear 209 drives the meshing connecting gear 210 to rotate, and the connecting gear 210 drives the meshing driven gear 211 to rotate. The driven gear 211 is connected to the axis of the support wheel 208, which in turn drives the support wheel 208 to rotate. During the rotation of the support wheel 208, the cylindrical component is pressed against the positioning plate 206. Sufficient friction is maintained between the support wheels 208, and the cylindrical part rotates synchronously with the support wheels 208 to adjust the printing angle. During this process, the positioning plate 206 always positions the part to prevent it from shifting forward or backward during rotation. Once the part has rotated to the target printing surface, the drive motor 213 stops working, and the support wheels 208 stop rotating. At this point, the print head 105 can perform UV printing on the current printing surface. The print head sprays UV-specific ink onto the surface of the cylindrical part, and simultaneously, the UV lamp rapidly irradiates it to instantly cure the ink. After printing this surface, the above support wheel 208 driving steps can be repeated to adjust the part angle and continue printing on other surfaces until the printing operation of the entire cylindrical part is completed.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
