Description

Technical Field

[0001] This utility model relates to the field of sphere processing technology, specifically a sphere printing device. Background Technology

[0002] With the increasing market demand for spherical product printing and decoration, existing spherical printing equipment, although technologically mature, still faces significant challenges in practical applications. In particular, the manual loading and unloading operation is not only inefficient and increases production costs, but also, in high-intensity production environments, may increase the labor intensity and risk of workplace injuries for employees. Furthermore, the safety risks during manual loading and unloading cannot be ignored. These shortcomings limit the production efficiency and quality stability of spherical printing equipment. Therefore, there is an urgent need to develop a spherical printing device with automatic loading and unloading to improve the level of production automation, ensure product quality, reduce production costs, and enhance work safety. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spherical printing device that solves the problem of manual loading and unloading required in traditional spherical printing devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spherical printing device, comprising a base, a support column on the upper part of the base, a circular plate seat rotatably mounted on the upper end of the support column, and four spherical grooves, adapted to the diameter of the sphere, equidistantly arranged in a circular matrix near the edge of the upper part of the circular plate seat. The spherical printing device further includes a material storage mechanism for storing and feeding the spheres, a printing mechanism for printing the spheres, a material unloading mechanism for unloading the printed spheres, and a drive mechanism for driving the circular plate seat to rotate.

[0005] The printing mechanism includes a printing support mounted on one side of the base. A movable seat is longitudinally slidably mounted on the outside of the printing support. An ink storage cylinder is mounted on the upper part of one side of the movable seat, and a printing head is mounted on the bottom of one side of the movable seat. The upper end of the printing head is connected to a pump built into the ink storage cylinder. An L-shaped rod is connected to the bottom of the movable seat at a position between the printing head and the printing support. A connecting rod is hinged to the other end of the L-shaped rod. A hydraulic cylinder is mounted on one side of the printing support. The output shaft of the hydraulic cylinder is connected to one side of the movable seat. The hydraulic cylinder drives the longitudinal movement of the movable seat, which causes the ink storage cylinder to drive the feeding mechanism to complete the ball feeding operation, and causes the connecting rod to drive the storage mechanism to complete the ball loading operation.

[0006] Preferably, the material storage mechanism includes a material storage support disposed on the side of the base away from the printing support. A material storage cylinder with an inner diameter adapted to the size of the ball is disposed on the upper side of the material storage support. A discharge groove adapted to the size of the ball is disposed at the lowest point on both sides of the material storage cylinder. The position of the discharge groove corresponds to the ball groove on the circular plate seat, so that when the ball groove passes through the discharge groove and the ball is pushed out, the ball can fall into the ball groove. The material storage mechanism also includes a push block adapted to the cross-sectional size of the discharge groove on the material storage cylinder. One end of the push block corresponds to the position of the discharge groove on one side of the material storage cylinder. The end of the connecting rod away from the L-shaped rod is hinged to the lower part of the end of the push block away from the material storage cylinder. When the printing head contacts the ball in the ball groove, the push block pushes out the lowest ball in the material storage cylinder and it falls into the ball groove. When the printing head returns to the initial position, the push block also returns to the initial position.

[0007] Preferably, side baffles are provided on both edges of the discharge trough near the circular plate seat on the storage cylinder. When the ball trough corresponds to the discharge trough on the storage cylinder, the two side baffles are located on both sides of the ball trough, and the side baffles are located on the upper part of the circular plate seat.

[0008] Preferably, the storage cylinder has grooves on both sides inside, and an arc-shaped spring is provided in the groove. The arc surface of the arc-shaped spring extends out of the groove to limit the bottom ball inside the storage cylinder and prevent the ball from moving out of the groove on the storage cylinder.

[0009] Preferably, a limiting groove is provided on one side of the support column and one side of the storage support, and the L-shaped rod passes through the limiting groove.

[0010] Preferably, the bottom of the circular plate seat is hinged with several stop bars in a ring matrix by torsion springs at the edge of the ball groove. When the torsion springs are in the reset state, the stop bars are in a horizontal state, supporting the ball in the ball groove.

[0011] Preferably, the driving mechanism includes a drive motor disposed on one side of the support column and a gear ring at the bottom of the circular plate seat. The output shaft of the drive motor is connected to a main gear, and the main gear meshes with the gear ring.

[0012] Preferably, the feeding mechanism includes a feeding support disposed on the rear side of the base. A T-shaped shaft is longitudinally slidably inserted into the upper part of one end of the feeding support. The lower end of the T-shaped shaft corresponds to the ball groove on the circular plate seat. A spring is also sleeved on the outside of the T-shaped shaft. The two ends of the spring are respectively connected to the upper part of the feeding support and the inner top side of the T-shaped shaft. A limit rod is provided on one side of the upper end of the T-shaped shaft. One end of the limit rod is connected to the ink storage cylinder. When the printing head contacts the ball, the lower end of the T-shaped shaft pushes the ball out of the ball groove.

[0013] This invention provides a spherical printing device, which has the following advantages compared with the prior art:

[0014] This spherical printing device can automatically replace manual labor in loading and unloading spheres, reducing the workload of workers and improving work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-Figure 5 This utility model provides two technical solutions: Example

[0023] Please see Figure 1In this embodiment of the utility model, a spherical printing device includes a base 1, a support column 2 is provided on the upper part of the base 1, a circular plate seat 3 is rotatably provided on the upper end of the support column 2, and four ball grooves 4 adapted to the diameter of the sphere are equidistantly arranged in a ring matrix near the upper part of the circular plate seat 3. The spherical printing device also includes a material storage mechanism 5 for storing and feeding the sphere, a printing mechanism 7 for printing the sphere, a material unloading mechanism 6 for unloading the printed sphere, and a driving mechanism 8 for driving the circular plate seat 3 to rotate.

[0024] Please see Figure 1 and Figure 2 In this embodiment of the present invention, the printing mechanism 7 includes a printing support 71 disposed on one side of the base 1. A movable seat 72 is longitudinally slidably sleeved on the outside of the printing support 71. An ink storage cylinder 73 is disposed on the upper part of one side of the movable seat 72, and a printing head 74 is disposed on the bottom side of one side of the movable seat 72. The upper end of the printing head 74 is connected to the pump built into the ink storage cylinder 73. An L-shaped rod 75 is connected to the bottom of the movable seat 72 at the position between the printing head 74 and the printing support 71. A connecting rod 76 is hinged to the other end of the L-shaped rod 75. A hydraulic cylinder 77 is installed on one side of the printing support 71. The output shaft of the hydraulic cylinder 77 is connected to one side of the movable seat 72. The hydraulic cylinder 77 drives the longitudinal movement of the movable seat 72, so that the ink storage cylinder 73 drives the feeding mechanism 6 to complete the ball feeding operation, and the connecting rod 76 drives the storage mechanism 5 to complete the ball feeding operation.

[0025] Please see Figure 1 and Figure 2 In this embodiment of the present invention, the storage mechanism 5 includes a storage support 51 disposed on the side of the base 1 away from the printing support 71. A storage cylinder 52 with an inner diameter adapted to the size of the sphere is disposed on the upper side of the storage support 51. Discharge grooves adapted to the size of the sphere are disposed at the lowest points on both sides of the storage cylinder 52. The positions of the discharge grooves correspond to the ball grooves 4 on the circular plate base 3, so that when the ball passes through the discharge grooves and the ball is pushed out, the ball can fall into the ball grooves 4. The storage mechanism 5 also includes... The push block 54 is adapted to the cross-sectional dimensions of the discharge groove on the storage cylinder 52. One end of the push block 54 corresponds to the position of the discharge groove on one side of the storage cylinder 52. The end of the connecting rod 76 away from the L-shaped rod 75 is hinged to the lower part of the end of the push block 54 away from the storage cylinder 52. When the printing head 74 contacts the ball in the ball groove 4, the push block 54 pushes out the lowest ball in the storage cylinder 52 and it falls into the ball groove 4. When the printing head 74 returns to the initial position, the push block 54 also returns to the initial position.

[0026] In the above scheme: when printing is required, the hydraulic cylinder 77 drives the movable seat 72 to move down, so that the printing head 74 contacts the ball in the ball groove 4. The pump built into the ink storage cylinder 73 draws ink onto the printing head 74, and the printing head 74 prints the pattern onto the ball. When the movable seat 72 moves down, it will drive the L-shaped rod 75 to move down. The L-shaped rod 75 causes the connecting rod 76 to drive the push block 54 to move laterally, so that it pushes out the bottom ball inside the storage cylinder 52. The second to last ball will press on the upper part of the push block 54. After the ball is pushed out, it will fall into the ball groove 4 when it passes through the ball groove 4, completing the ball loading work.

[0027] For further details, please refer to Figure 1 In this embodiment of the present invention, side baffles 53 are provided on both edges of the discharge groove near the circular plate seat 3 on the storage cylinder 52. When the ball groove 4 corresponds to the discharge groove on the storage cylinder 52, the two side baffles 53 are located on both sides of the ball groove 4, and the side baffles 53 are located on the upper part of the circular plate seat 3. When the ball is pushed into the ball groove 4, the ball can smoothly enter the ball groove 4 under the action of the side baffles 53.

[0028] For further details, please refer to [link / reference]. Figure 5 In this embodiment of the present invention, grooves 521 are provided on both sides of the inside of the storage cylinder 52, and an arc-shaped spring piece 522 is provided in the groove 521. The arc surface of the arc-shaped spring piece 522 extends out of the groove 521 to limit the bottom ball inside the storage cylinder 52 and prevent the ball from moving out of the groove on the storage cylinder 52.

[0029] For further details, please refer to Figure 5 In this embodiment of the utility model, a limiting groove 21 is provided on one side of the support column 2 and one side of the storage support 51. The L-shaped rod 75 passes through the limiting groove 21, and the limiting groove 21 plays a role in limiting and guiding the longitudinal movement of the L-shaped rod 75.

[0030] For further details, please refer to Figure 3 and Figure 4 In this embodiment of the present invention, the bottom of the circular plate seat 3 is located at the edge of the ball groove 4 and is hinged with several baffles 42 in a ring matrix by torsion springs 41. When the torsion springs 41 are in the reset state, the baffles 42 are in a horizontal state, supporting the ball in the ball groove 4.

[0031] For further details, please refer to Figure 1 and Figure 3In this embodiment of the utility model, the driving mechanism 8 includes a driving motor 81 disposed on one side of the support column 2 and a gear ring 82 at the bottom of the circular plate seat 3. The output shaft of the driving motor 81 is connected to a main gear 83, which meshes with the gear ring 82. When the push block 54 pushes the ball into the ball groove 4, the driving motor 81 drives the main gear 83 to rotate. Since the main gear 83 meshes with the gear ring 82 at the bottom of the circular plate seat 3, the rotation of the main gear 83 drives the circular plate seat 3 to rotate, causing it to rotate 90 degrees. In this way, the ball being fed will move to the bottom of the printing head 74, the printed ball will move to the bottom of the T-shaped shaft 62, and the empty ball groove 4 will move to the position of the storage mechanism 5.

[0032] Example 2 differs from Example 1 in that:

[0033] Please see Figure 1 In this embodiment of the utility model, the feeding mechanism 6 includes a feeding support 61 disposed on the rear side of the base 1. A T-shaped shaft 62 is longitudinally slidably inserted into the upper part of one end of the feeding support 61. The lower end of the T-shaped shaft 62 corresponds to the ball groove 4 on the circular plate seat 3. A spring 63 is also sleeved on the outside of the T-shaped shaft 62. The two ends of the spring 63 are respectively connected to the upper part of the feeding support 61 and the inner top side of the T-shaped shaft 62. A limit rod 64 is provided on one side of the upper end of the T-shaped shaft 62. One end of the limit rod 64 is connected to the ink storage cylinder 73. When the printing head 74 contacts the ball, the lower end of the T-shaped shaft 62 pushes the ball in the ball groove 4 out.

[0034] In the above scheme: when the moving seat 72 moves down, it also drives the ink storage cylinder 73 to move down. The ink storage cylinder 73 drives the limiting rod 64 to move down. Under the elasticity of the spring 63, the limiting rod 64 drives the T-shaped shaft 62 to move down. The lower end of the T-shaped shaft 62 pushes the ball inside the ball groove 4, pressing the printed ball down. Under the elasticity of the torsion spring 41, as the ball is pressed down, the ball will drive each stop bar 42 to rotate downward, eventually causing the ball to fall. After falling, the torsion spring 41 will reset the stop bar 42, which facilitates the support of the loaded ball.

[0035] Working principle: When printing is required, the hydraulic cylinder 77 drives the moving seat 72 to move down, so that the printing head 74 contacts the ball in the ball groove 4. The pump built into the ink storage cylinder 73 draws ink onto the printing head 74, and the printing head 74 prints the pattern onto the ball.

[0036] When the moving seat 72 moves down, it will drive the L-shaped rod 75 to move down. The L-shaped rod 75 causes the connecting rod 76 to drive the push block 54 to move laterally, so that it pushes out the bottom ball inside the storage cylinder 52. The second to last ball will press on the top of the push block 54. After the ball is pushed out, it will fall into the ball groove 4 when it passes through the ball groove 4, thus completing the ball loading work.

[0037] As the moving seat 72 moves downward, it also drives the ink reservoir 73 to move downward. The ink reservoir 73 drives the limiting rod 64 to move downward. Under the elasticity of the spring 63, the limiting rod 64 drives the T-shaped shaft 62 to move downward. The lower end of the T-shaped shaft 62 pushes the ball inside the ball groove 4, pressing the printed ball downward. Under the elasticity of the torsion spring 41, as the ball is pressed down, the ball will drive each stop bar 42 to rotate downward, eventually causing the ball to fall. After falling, the torsion spring 41 will reset the stop bar 42, which facilitates the support of the loaded ball.

[0038] When the pusher block 54 pushes the ball into the ball groove 4, the drive motor 81 drives the main gear 83 to rotate. Since the main gear 83 meshes with the gear ring 82 at the bottom of the circular plate seat 3, the rotation of the main gear 83 drives the circular plate seat 3 to rotate, making it rotate 90 degrees. In this way, the ball being fed will move to the bottom of the printing head 74, the printed ball will move to the bottom of the T-shaped shaft 62, and the empty ball groove 4 will move to the position of the storage mechanism 5. Then the hydraulic cylinder 77 drives the moving seat 72 to move upward, so that the pusher block 54 and the T-shaped shaft 62 return to the initial state. After that, the above steps are repeated to form a continuous operation.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
