Description

Technical Field

[0001] The utility model relates to a multi-station turntable balancing mechanism for a screen printing machine. Background Art

[0002] Currently, the majority of the printing process in the screen printing industry is still manually performed, from placing and calibrating the screen printing plate to printing and drying. Furthermore, bottles must be manually placed one by one on the screen printing machine for printing. This results in relatively low efficiency, and requires multiple screen printing machines for mass production, resulting in high costs and difficulty meeting the development needs of small and medium-sized enterprises. Furthermore, existing screen printing machines are often only capable of printing a single color. To print multiple colors, multiple screen printing machines are required, which is often very costly.

[0003] The utility model with patent application number 201820041084.7 discloses a fully automatic three-color screen printing machine. By setting a first printing device, a second printing device and a third printing device, the material can be printed in three different colors. In this way, three different colors can be printed on one device, saving costs. That is, a multi-station printing mechanism is used for production and processing, but multiple printing mechanisms are assembled on a turntable, which will affect the structural stability of the turntable. The turntable recorded in the document has the above-mentioned problem. The turntable balance cannot be achieved, resulting in low stability and adjustability of the turntable, high operating noise, and reduced printing quality. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a multi-station turntable balancing mechanism for a screen printing machine.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A multi-station turntable balancing mechanism for a screen printing machine includes a platform, a multi-station turntable located inside the platform, a power device located below the multi-station turntable and driving the multi-station turntable to rotate, and a plurality of balancing components fixedly mounted on the bottom of the platform and abutting and supporting the multi-station turntable. The balancing components are equidistantly distributed around the multi-station turntable. The balancing components include a mounting plate fixed to the platform by bolts, a metal horizontal bar welded below the mounting plate, a metal vertical bar fixedly mounted on one side of a bar block, and a roller mounted on the upper end of the metal vertical bar and in contact with the ground of the multi-station turntable.

[0007] Preferably, a groove is formed above one end of the metal horizontal bar close to the metal vertical bar.

[0008] Preferably, a embedding groove is provided on a side of the metal vertical bar facing the metal horizontal bar, and the metal vertical bar is further provided with two strip-shaped holes parallel to each other on the embedding groove.

[0009] Preferably, the stand includes a rectangular platform with a hollow interior and a frame strip laid on the lower edge of the rectangular platform.

[0010] Preferably, the multi-station turntable includes a turntable body, a driven gear fixedly mounted at a central position below the turntable body, and a support shaft passing through the driven gear and the turntable body.

[0011] Furthermore, a turntable bearing seat assembled with the support shaft is fixedly installed at the center of the turntable body.

[0012] Furthermore, an assembly frame is fixedly installed above the driven gear by bolts.

[0013] Furthermore, a support sleeve is fixedly installed on the lower end of the support shaft by bolts, and a gear support bearing is sleeved on the support shaft and fixedly installed with the support sleeve.

[0014] Preferably, the power device includes a reducer with a driving gear installed at the output end, and a servo motor assembled at the lower end of the reducer and connected to the reducer at the output end.

[0015] The beneficial effects of the utility model are:

[0016] 1. Improved stability: The balancing component supports the turntable through rollers, which can effectively distribute the weight of the turntable and avoid tilting due to uneven load or rotation, thereby improving the stability of the multi-station turntable and ensuring smooth operation of each station during the screen printing process;

[0017] 2. Prevent the turntable from tilting: Through the precise balancing design, especially the combination of rollers and support components, the turntable can maintain its horizontal state during rotation, preventing the uneven center of gravity or tilt caused by rotation from affecting printing accuracy, ensuring long-term stable operation of the equipment;

[0018] 3. Strong Adjustability: The balancing component design includes multiple adjustable structures, such as the grooves and holes in the metal vertical bars, and the position adjustment of the rollers. These designs enable the mechanism to be fine-tuned according to different working conditions during use to adapt to different work needs and enhance the flexibility of the equipment.

[0019] 4. Reduce load and noise: The multi-station turntable balancing mechanism reduces the burden on the power system and the demand for servo motors by reasonably distributing the load on the turntable, thereby reducing power consumption and noise during equipment operation and improving the comfort of the working environment;

[0020] 5. Improve production efficiency: Since the turntable can remain stable during rotation, avoiding operational errors or shutdowns caused by tilting, the overall production process is smoother, reducing downtime and maintenance costs, thereby improving production efficiency.

[0021] 6. Improve printing quality: Since the turntable can remain stable, the center of gravity and position of each station will not change during the printing process, which can effectively avoid errors or quality fluctuations in the printing process, thereby improving the accuracy and quality of printing.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Example

[0028] like Figure 1-4 As shown, a multi-station turntable balancing mechanism for a screen printing machine includes a stand 1, a multi-station turntable 2 located inside the stand 1, a power device 3 located below the multi-station turntable 2 and driving the multi-station turntable 2 to rotate, and a plurality of balancing components 4 fixedly installed on the bottom of the stand 1 and abutting against the multi-station turntable 2 for support, and the balancing components 4 are equidistantly distributed around the multi-station turntable 2.

[0029] The stand 1 includes a rectangular platform 11 with a hollow interior and a frame strip 12 laid on the lower edge of the rectangular platform 11 .

[0030] The multi-station turntable 2 includes a turntable body 21 , a driven gear 22 fixedly mounted at a central position below the turntable body 21 , and a support shaft 23 passing through the driven gear 22 and the turntable body 21 .

[0031] A turntable bearing seat 211 assembled with the support shaft 23 is fixedly mounted at the center of the turntable body 21 .

[0032] An assembly bracket 221 is fixedly installed above the driven gear 22 by means of bolts. Specifically, the driven gear 22 is fixedly installed to the turntable body 21 by means of the assembly bracket 221 .

[0033] The lower end of the support shaft 23 is fixed with a support sleeve 231 by bolts, and a gear support bearing 232 is mounted on the support shaft 23 and fixed to the support sleeve 231. Specifically, the gear support bearing 232 is assembled with the driven gear 22, and supports the turntable body 21 fixed to the turntable body 21 through the support sleeve 231.

[0034] The power device 3 includes a reducer 31 with a driving gear installed at the output end, and a servo motor 32 assembled at the lower end of the reducer 31 and connected to the reducer 31 at the output end. Specifically, the reducer 31 and the servo motor 32 are both fixedly installed on the main frame of the screen printing machine.

[0035] The balancing assembly 4 includes a mounting plate 41 fixed to the stand by bolts, a metal horizontal bar 42 welded to the bottom of the mounting plate 41, a metal vertical bar 43 fixedly mounted on one side of the bar block 42, and a roller 44 assembled on the upper end of the metal vertical bar 43 and in contact with the ground of the multi-station turntable 2.

[0036] A groove 421 is formed above one end of the metal horizontal bar 42 close to the metal vertical bar 43. Specifically, the size of the groove 421 is larger than the roller 44, so that when the metal vertical bar 43 is adjusted up and down, the groove 421 can accommodate the roller 44 without affecting the normal rotation of the roller 44.

[0037] A groove 431 is provided on one side of the metal vertical bar 43 facing the metal horizontal bar 42, and two parallel strip holes 432 are provided on the metal vertical bar 43. Specifically, when one end of the metal horizontal bar 42 with the groove 421 is embedded in the groove 431, the metal vertical bar 43 is raised and lowered so that the roller 44 abuts against the multi-station turntable 2, and then a bolt is screwed into the metal horizontal bar 42 through the strip hole 432, so that the metal horizontal bar 42 and the metal vertical bar 43 are fixed and assembled.

[0038] It should be further explained that the roller 44 abuts against and supports the multi-station turntable 2 , thereby reducing the multi-station turntable 2 from tilting to one side due to excessive weight when rotating.

[0039] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
