Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of enamel pot processing, in particular to an automatic spraying equipment for enamel pot glaze. BACKGROUND

[0002] In the production process of enamel pots, glaze spraying is a key link for shaping product appearance and giving protective performance. With the market's increasing demand for enamel pot quality (appearance consistency, glaze uniformity) and production efficiency, traditional manual spraying has been difficult to adapt to large-scale production due to low efficiency and large quality fluctuations. Automated spraying equipment, with the advantages of precise control and continuous operation, has become the core equipment for cost reduction and efficiency improvement in the industry, promoting the intelligent upgrading of enamel pot manufacturing. It needs to consider multi-process connection and multi-station cooperation to meet the needs of efficient production.

[0003] The existing automatic glaze spraying equipment for enamel pots is composed of a spraying mechanical arm, a glaze supply system (storage tank, spray gun, conveying pipeline), a support transmission assembly, and a control system. The support transmission assembly includes an I-shaped electric adjusting frame and multiple support seats. The middle of the adjusting frame is provided with a rotating shaft that can drive the whole to rotate periodically. The function is "station switching", which turns the sprayed pot to the feeding position and simultaneously turns the unsprayed pot to the spraying position. The adjusting frame has multiple drive mechanisms built-in at both ends, corresponding to the support seats. The drive mechanisms can independently drive the support seats to rotate to ensure uniform spraying of the pot in all directions. In the operation process, the mechanical arm sprays the glaze on the pot (fixed in position by the corresponding support seat when spraying inside / outside the pot) in the spraying position according to the preset trajectory, in coordination with the flow and pressure parameters of the spray gun. The rotating shaft of the adjusting frame is linked to switch the stations to ensure the continuity of production.

[0004] The existing equipment requires different fixed positions for spraying inside and outside the pot (the support seat needs to adapt to the inverted mounting of the pot body for spraying inside the pot, and to the upright mounting for spraying outside the pot). The electric adjusting frame and drive mechanism can only realize "station transfer" and cannot be compatible with support seats in both positions. This results in the need for users to purchase two independent devices, one with support seats suitable for spraying inside the pot and the other with support seats suitable for spraying outside the pot. The cost of equipment procurement is directly multiplied, and the double equipment occupies a large area and requires coordination of the station connection of the two devices for production scheduling, increasing the management complexity. The non-universal support seats also cause high spare parts storage costs, complicated equipment replacement and debugging, and other problems, making it difficult to achieve intensive use of equipment while ensuring spraying quality and production continuity, and requiring breakthroughs in the scene adaptation of the support transmission assembly.

[0037] For example, a plurality of limit grooves 91 corresponding to the clamping block 9 are equally angularly provided on the outer support plate 6, the limit grooves 91 are used to limit the movement track of the clamping block 9 to ensure that the clamping block 9 can only slide to avoid rotating with the screw rod 10.

[0038] The driving assembly in this embodiment includes a spur gear 11, a face gear 12, a gear ring 13 and a rack 14. The spur gear 11 is fixedly installed at the end of the screw rod 10; the face gear 12 is rotatably installed in the outer support plate 6 and is meshingly connected with multiple spur gears 11, the diameter of the face gear 12 is greater than the diameter of the inner support plate 3 and is staggered with the installation position of the inner support plate 3 to avoid mutual interference; the gear ring 13 is installed at the bottom of the face gear 12 and is rotatably connected with the outer support plate 6; the rack 14 is arranged below the outer support plate 6 and is meshingly connected with the gear ring 13, and the rack 14 is meshed with multiple gear rings 13 in the outer support plate 6 to synchronously drive the clamping blocks 9 of multiple outer support plates 6 to adjust.

[0039] Exemplary, the bottom outer wall of the out-of-pot supporting disc 6 is provided with an opening 61 corresponding to the gear ring 13, the outer side of the gear ring 13 is exposed through the opening 61 and is connected with the gear rack 14 in meshing, to ensure smooth transmission; the lifting frame 5 is provided with a supporting frame 15 corresponding to the gear rack 14, the supporting frame 15 is provided with an installation slot 16 penetrating through and movably connected with the gear rack 14, the installation slot 16 is used for limiting the position of the outer wall on both sides of the gear rack 14, and the length of the installation slot 16 is greater than the sum of the thicknesses of the gear rack 14 and the gear ring 13, to provide space for the lifting of the gear rack 14.

[0040] The bottom of the supporting frame 15 in the embodiment is rotatably provided with a control plate 17 corresponding to the gear rack 14, and the control plate 17 is designed in an L-shaped cross section, the end surface of the control plate 17 is attached to the bottom surface of the gear rack 14 after rotation, and is used for pushing the gear rack 14 to slide upwards and mesh with the gear ring 13; the control end of the control plate 17 is located outside the supporting frame 15, to facilitate operation; the end surface of the control plate 17 attached to the bottom surface of the gear rack 14 is designed in a plane, and the edges and corners are designed in an arc-shaped round corner, to ensure that the control plate 17 can smoothly push the gear rack 14 upwards; the end of the gear rack 14 is provided with a driving handle 141, to facilitate pushing or pulling the gear rack 14.

[0041] Through the cooperation of the above components, when the enamel pot is sprayed in the pot, the adjusting clamp block 9 clamps the enamel pot in place, and the out-of-pot supporting disc 6 rotates with the driving shaft 2 to realize uniform spraying; when the enamel pot is sprayed outside the pot, the lifter 4 drives the lifting frame 5 to descend, so that the out-of-pot supporting disc 6 is separated from the in-pot supporting disc 3, the enamel pot is inverted and buckled on the in-pot supporting disc 3, and the in-pot supporting disc 3 rotates with the driving shaft 2 to realize uniform spraying of the outer wall, thereby realizing that one device is compatible with two spraying scenes and reducing the equipment investment and management cost.

[0042] The working principle of the enamel pot spraying device is as follows: when the inside of the enamel pot needs to be sprayed, the position of the adjusting clamp block 9 needs to be adjusted to adapt to the size of the pot body, the arc-shaped round corner of the end of the control plate 17 at the bottom of the supporting frame 15 is first in contact with the bottom surface of the gear rack 14 by rotating the control plate 17; as the control plate 17 continues to rotate, the plane end of the L-shaped structure pushes the gear rack 14 upwards, so that the gear rack 14 slides upwards along the installation slot 16 of the supporting frame 15, until the gear rack 14 is connected with the position of the gear ring 13 exposed through the opening 61 in meshing; if the gear teeth of the gear rack 14 and the gear ring 13 are misaligned, the position can be adjusted by adjusting the driving handle 141 at the end of the gear rack 14, to ensure accurate meshing; Then, the remaining control plates 17 are rotated, so that the end surfaces of the control plates 17 are attached to the bottom surfaces of the gear racks 14, to support the gear racks 14 from below and ensure that the meshing state of the gear racks 14 and the gear rings 13 is stable; Subsequently, the gear racks 14 are pushed or pulled by the driving handles 141, the gear racks 14 drive the gear rings 13 in the multiple out-of-pot supporting discs 6 to rotate synchronously; as the gear rings 13 are fixedly connected with the face gear 12, the face gear 12 is further driven to rotate; the face gear 12 is meshed with the multiple spur bevel gears 11, so that the spur bevel gears 11 drive the corresponding screw rods 10 to rotate; Under the action of the screw rod 10, the clamping block 9 slides along the limiting groove 91 of the outer pot support disc 6, and the limiting groove 91 ensures that the clamping block 9 only moves linearly. Multiple sets of clamping blocks 9 are synchronized to move close to or away from the center until they are adjusted to a position suitable for the outer wall of the enamelled pot to be sprayed; When the position adjustment of the clamping block 9 is completed, the control plate 17 is reversed to release the support on the rack 14, and the rack 14 slides downward along the mounting groove 16 under the action of its own gravity, and is separated from the tooth ring 13 to avoid interference when the outer pot support disc 6 rotates subsequently; Then, the enamelled pot is placed on the outer pot support disc 6, and the clamping block 9 limits the pot body from the outside. The I-shaped electric adjusting frame 1 is started to transfer the enamelled pot to the spraying position. During spraying, the driving shaft 2 starts to rotate, which drives the outer pot support disc 6 to rotate synchronously through the shaft groove 7 corresponding to the notch shape of the driving shaft 2, so that the spray gun can uniformly spray the inner surface of the pot, and the inner spraying work is completed. When the outer wall of the enamelled pot needs to be sprayed, first ensure that the rack 14 has been separated from the tooth ring 13. Then, the lifter 4 is started, at this time, the lifter 4 drives the lifting frame 5 to move downward, causing the outer pot support disc 6 to descend synchronously with the lifting frame 5. At this time, the driving shaft 2 limits the downward trajectory of the outer pot support disc 6 through the shaft groove 7 to ensure its smooth movement. As the outer pot support disc 6 descends, the inner pot support disc 3 gradually separates from the receiving groove 8 of the outer pot support disc 6. When the lifting frame 5 descends to a limited height, the outer pot support disc 6 is completely separated from the inner pot support disc 3, and the inner pot support disc 3 is exposed as a whole. At this time, the operator can place the enamelled pot upside down on the inner pot support disc 3 (because the top of the existing inner pot support disc 3 will be provided with a friction pad and other components for ensuring that the inner pot support disc 3 can smoothly drive the enamelled pot to rotate, which is prior art and is not described in detail). The inverted enamelled pot is transferred to the spraying position by the I-shaped electric adjusting frame 1, and the driving shaft 2 directly drives the inner pot support disc 3 and the inverted enamelled pot to rotate, so that the spray gun can uniformly spray the outer wall of the pot body, and the outer wall spraying work is completed. The device realizes the integrated operation of the inner and outer wall spraying of the enamelled pot through the coordinated linkage of the mechanical structure, simplifies the operation process, reduces the equipment investment, and is suitable for large-scale enamelled pot production scenes.

The specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification, as long as they are within the scope of the claims of the present application.
