Description

Technical Field

[0001] This utility model relates to the field of coating equipment, and in particular to a shaft coating equipment for printing roller production. Background Technology

[0002] Rubber rollers are typically made of synthetic rubber or polyurethane with excellent elasticity and ink affinity. They are precisely installed in the printing unit, and their core mission is to transfer ink evenly, smoothly and quantitatively onto the printing plate in a complex ink transfer system. The performance of the rubber rollers directly determines the quality of the printed matter.

[0003] When applying coating to the shaft core of a printing roller, the shaft core must first be installed. Since both ends of the shaft core are fixed with long connecting rods, the connecting rods are usually clamped directly during installation. During operation, the shaft core is moved to the clamping device, and the connecting rods are inserted into the clamping device. During the clamping process, the shaft core needs to be manually supported, and the clamping work is completed by multiple clamping plates. In this process, manual support is quite laborious, and since manual support cannot guarantee the stability of the shaft core, it is not conducive to clamping the connecting rods of the shaft core.

[0004] Therefore, it is necessary to provide a new spindle coating device for printing roller production to solve the above-mentioned technical problems. Utility Model Content

Both telescopic components are fixed to the mounting plate, and shielding frames are fixed to the telescopic ends of both telescopic components.

[0008] Preferably, the rotating device includes a rotating component, a driving wheel, a rotating ring, and a driven wheel. The driving wheel is rotatably connected to the upright plate, the rotating component is used to drive the driving wheel to rotate, the rotating ring is rotatably connected to the upright plate, the driven wheel is fixed on the rotating ring, and the driven wheel meshes with the driving wheel.

[0014] Compared with related technologies, the shaft core coating device for printing rubber roller production provided by this utility model has the following beneficial effects:

[0015] This application uses two mounting plates to support the shaft core first, and then pushes the shaft core towards the clamping device. During the clamping process, the shaft core is supported by multiple universal balls on the two mounting plates, eliminating the need for manual support and saving the labor of workers. Moreover, since the shaft core is directly mounted on the mounting plates, it is less likely to move compared to traditional manual support, which facilitates the clamping operation of the clamping device.

[0024] In the specific implementation process, such as Figures 1-5 As shown, the device includes a base plate 1 on which a spraying device is mounted. The base plate 1 also has two opposing mounting devices. One mounting device has a vertical plate 2 on one side, with an insertion hole 3. A clamping device and a rotating device are also located on one side of the vertical plate 2. The rotating device drives the clamping device to rotate. The mounting device includes a mounting plate 4, two telescopic members 20, and two shielding frames. The mounting plate 4 is fixed to the base plate 1. A placement groove 6 is formed at the top of the mounting plate 4, and the bottom of the placement groove 6 has a semi-circular structure. A universal ball 5 is movably connected to the semi-circular structure on the placement groove 6. The semi-circular structure is coaxially arranged with the center of the clamping device. Both telescopic members 20 are fixed to the mounting plate 4, and shielding frames are fixed to the telescopic ends of both telescopic members 20. The telescopic member 20 is a second electric cylinder.

[0025] When applying adhesive to the shaft core, the connecting rods at both ends of the shaft core are respectively mounted on two mounting plates 4. Since the connecting rods have a certain length, the shaft core can be pushed towards the vertical plate 2. The two connecting rods move on the universal balls 5 on the two mounting plates 4, causing the universal balls 5 to rotate. When one end of the connecting rod passes through the insertion hole 3 and is located in the center of the clamping device, it is clamped by the clamping device. The rotating device drives the clamping device to rotate, realizing the rotation of the shaft core. The rotation of the two connecting rods drives the multiple universal balls 5 to rotate. The spraying device realizes the adhesive spraying effect on the shaft core.

[0026] The rotating device includes a rotating component, a driving wheel 7, a rotating ring 8, and a driven wheel 9. The driving wheel 7 is rotatably connected to the upright plate 2.

The driven wheel 9 is fixed on the rotating ring 8 and meshes with the driving wheel 7. The rotating component includes a bracket 19 and a motor 11. The bracket 19 is fixed on the upright plate 2, and the motor 11 is fixed on the bracket 19. The output end of the motor 11 is fixedly connected to the driving wheel 7.

[0027] The motor 11 drives the drive wheel 7 to rotate, which in turn drives the rotating ring 8 and the driven wheel 9 to rotate, thus realizing the rotation of the clamping device.

[0028] The clamping device includes multiple first electric cylinders 12 and multiple clamping arc plates 13. The multiple first electric cylinders 12 are all fixed on the inner wall of the rotating ring 8, and the telescopic ends of the first electric cylinders 12 are fixedly connected to the clamping arc plates 13. The multiple first electric cylinders 12 are evenly distributed in a ring. By extending the multiple first electric cylinders 12, the multiple clamping arc plates 13 are driven to move towards the connecting rod of the shaft core, which facilitates the clamping operation of the shaft core.

[0029] The spraying device includes a spray frame 14, a spray pipe 15, and a guide pipe 16. The spray frame 14 is fixed on the base plate 1. The spray pipe 15 has a closed structure at both ends and is fixed on the spray frame 14. Multiple nozzles are fixedly installed on the spray pipe 15. One end of the guide pipe 16 is fixedly connected to the spray pipe 15. The guide pipe 16 is connected to a glue tank. The spraying glue is drawn into the guide pipe 16 by the pump body, and then sprayed out from the nozzles after passing through the spray pipe 15 and acting on the shaft core.

[0030] The shielding frame includes a vertical plate 17 and a horizontal plate 18. The vertical plate 17 and the horizontal plate 18 are fixedly connected. A semi-circular receiving hole is provided on the vertical plate 17. The horizontal plate 18 is located above the placement groove 6.
