[0001] The utility model belongs to mechanical engineering and manufacturing technical field, concretely relates to a balloon printing machine rotary chuck. BACKGROUND

[0002] In the prior art, the traditional balloon printing equipment is installed with several rotary chuck components on the annular conveying belt driven by the motor, and these rotary chuck components are usually made of iron. Although these rotary chucks can meet the basic printing requirements, they have some limitations, for example, the iron chuck is relatively heavy due to its material properties. This increases the load of the printing equipment, causes the machine to wear out more quickly, and requires more maintenance and repair work, and the iron chuck requires more driving power to realize the rotation function, thereby increasing the energy consumption. Due to the relatively simple design of the iron chuck, there is a lack of precise positioning mechanism, and it is difficult to ensure the accuracy of the position after each rotation, resulting in a decrease in printing quality. In view of the above challenges, it is necessary to develop a new type of rotary chuck. SUMMARY

[0003] The utility model aims at providing a balloon printing machine rotary chuck, which ensures the accuracy and consistency of each rotation through a positioning mechanism, and reduces wear and tear through a press connection and lightweight design, thereby prolonging the service life of the chuck.

[0004] To achieve the above-mentioned purpose, the utility model provides a balloon printing machine rotary chuck, which comprises a chuck support, the chuck support is of an annular structure, the inner wall of the chuck support is provided with a positioning hole, the inner wall and the outer wall of the chuck support are provided with a reinforcing rib, one side of the chuck support is provided with a connecting arm, the lower side of the chuck support is provided with a groove, the chuck support is connected with the chuck inner core, the outer circumferential surface of the chuck inner core is provided with a boss, the middle part of the chuck inner core is provided with an equal distribution type positioning groove, the positioning groove is installed with a positioning bead, the lower side of the chuck inner core is installed with a rear cover.

[0005] Preferably, one side of the connecting arm is provided with a mounting hole and a U-shaped groove.

[0006] Preferably, the chuck support and the chuck inner core are connected by press connection, the groove and the boss are matched, and after press connection, the boss and the groove are tightly connected.

[0007] Preferably, the interval between the positioning grooves is 90 degrees, and the shape of the positioning groove is semicircular arc.

[0008] Preferably, the chuck inner core is of a cylindrical structure, the top of the chuck inner core is provided with a mounting groove, and the bottom of the chuck inner core has four outwardly extending feet.

[0009] Preferably, the feet are evenly distributed, with a 90-degree interval between the feet, and the ends of the feet are rounded.

[0010] Therefore, the balloon printing machine rotating chuck has the following remarkable beneficial effects compared with the prior art:

[0011] (1) The utility model adopts the stifled pressure connection, reduces the friction and abrasion between the mechanical parts, prolongs the equipment service life;

[0012] (2) The utility model provides good sealing and protection function, prevents the influence of external factors on internal components;

[0013] (3) The utility model through accurate positioning mechanism and reasonable internal structure design, ensure the accuracy and consistency after each rotation;

[0014] (4) The utility model adopts light but solid material (such as new plastic) instead of traditional iron material. This not only reduces the weight of single chuck, but also reduces the load of the equipment as a whole due to the need to install several chucks on the ring-shaped conveyor belt. Lighter load makes the required torque output of the motor driving the ring-shaped conveyor belt reduce, thereby effectively reducing energy consumption and realizing energy saving and emission reduction.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by those skilled in the art.

[0023] Example 1

[0024] like Figure 1 As shown, this utility model discloses a rotating chuck for a balloon printing machine. The chuck bracket 1 is the basic structure of the entire rotating chuck, providing a platform for the installation and fixation of other components. The chuck bracket 1 is made of a sturdy yet lightweight material (such as a novel plastic) to reduce overall weight and improve durability. The main body of the chuck bracket 1 is a ring structure for accommodating and fixing the chuck core 8. Positioning holes 3 are provided on the inner wall of the chuck bracket 1. Multiple reinforcing ribs 4 are designed between the inner and outer walls of the chuck bracket 1 to enhance the overall strength of the bracket and prevent deformation.

[0025] A connecting arm 5 is provided on one side of the chuck bracket 1. A mounting hole 6 and a U-shaped groove 7 are provided on one side of the connecting arm 5 for connecting to the base. The design of the connecting arm 5 ensures the overall stability and strength of the bracket. The chuck inner core 8 has a cylindrical structure. A mounting groove 13 is provided at the top of the chuck inner core 8 for mounting other components. The bottom of the chuck inner core 8 has four outwardly extending feet 14, which are evenly distributed with a 90-degree interval between each foot 14. The ends of the feet 14 are rounded to reduce friction, improve wear resistance, and prevent scratches and damage.

[0026] A groove 2 is provided on the lower side of the chuck holder 1, and a boss 10 is provided on the outer circumferential surface of the chuck inner core 8, which matches the groove 2. The chuck inner core 8 is fixed to the chuck holder 1 by a pressing method. After pressing, the boss 10 and the groove 2 are tightly connected, ensuring that the chuck inner core 8 can be firmly fixed in the chuck holder 1, while allowing it to rotate freely. The pressing method not only provides a stable connection, but also reduces friction and wear, extending the service life of the chuck.

[0027] The middle part of the chuck inner core 8 is provided with uniformly distributed positioning grooves 9, the interval between the positioning grooves 9 is 90 degrees, and the shape of the positioning groove 9 is a semicircular arc shape matched with the outer shape of the positioning bead 11. The positioning bead 11 is installed in the positioning groove 9. The positioning bead 11 is used in cooperation with the positioning hole 3 on the chuck inner core 8, and the width of the positioning hole 3 is slightly larger than the diameter of the positioning bead 11. When the chuck inner core 8 is not rotated to the preset angle, the positioning bead 11 is in an uncooperative state with the positioning hole 3. At this time, the positioning bead 11 maintains a relatively stable position in the mounting structure of the chuck support 1. When the chuck inner core 8 starts to rotate, the positioning bead 11 gradually approaches the corresponding positioning hole 3 with the rotation of the chuck inner core 8. When the chuck inner core 8 rotates to the preset angle, the positioning bead 11 is just aligned with the positioning hole 3, and the positioning bead 11 is embedded into the positioning hole 3. Since the shape and size of the positioning hole 3 are matched with the positioning bead 11, the positioning bead 11 is limited in the positioning hole 3, thereby realizing the positioning effect.

[0028] The rear cover 12 is fixed on the chuck inner core 8 by screws, covers and protects the internal components from the external environment. In addition to preventing dust, moisture and other things from entering the inside to affect the operation of the equipment, it can also provide additional safety protection to avoid damage to internal components caused by accidental collision.

[0029] Therefore, the balloon printing machine rotating chuck adopts the above-mentioned rotating chuck, which ensures the accuracy and consistency of each rotation through the positioning mechanism, and adopts the damp pressing connection and lightweight design, thereby prolonging the service life of the chuck, reducing the machine wear and tear, and reducing the energy consumption.

[0030] Finally, it should be noted that: the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit it, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: it can still modify or equivalently replace the technical scheme of the utility model, and these modifications or equivalent replacements cannot make the modified technical scheme deviate from the spirit and scope of the technical scheme of the utility model.
