Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for paint production, specifically a feeding device for paint production lines. Background Technology

[0002] Paint refers to a coating applied to the surface of an object to be protected or decorated, forming a continuous, firmly adhering film. It is typically a viscous liquid made primarily of resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, formulated with organic solvents or water. Paints have strong hiding power, and their main functions are fourfold: protection, decoration, concealing product defects, and other special functions to enhance product value. Therefore, they are widely used in various industries and fields.

[0003] Since coatings are generally composed of film-forming substances (resins, emulsions), pigments (including extender pigments), solvents, and additives (auxiliaries), the selected raw materials need to be mixed and stirred during the coating preparation process to obtain the desired coating. In actual production, since the purchased raw materials are generally packaged in drums, 200L iron drums need to be lifted to pour the liquid raw materials into the reaction vessel. This existing feeding method is not only labor-intensive and time-consuming but also poses safety hazards. Furthermore, manual handling or feeding easily spills liquid raw materials onto the production site, polluting the environment and wasting materials. If spilled liquid drips onto operators, it can cause unpredictable injuries. Therefore, it is essential to provide a convenient feeding device to facilitate pouring liquid raw materials into the reaction vessel, reduce labor costs, and eliminate safety hazards. Utility Model Content

The hand crank mechanism 5 is disposed in the mounting frame 3. Under the action of the lifting mechanism 2, the mounting frame 3 can move up and down along the support frame 12, while the support mechanism 4 can rotate around the mounting frame 3 under the action of the hand crank mechanism 5. The base frame 11 includes two base plates and one cross plate, which are welded together to form a frame structure. The support frame 12 includes two support plates and one connecting plate, which are welded together to form a frame structure. The two support plates are vertically fixed to the corresponding two base plates in the base frame 11, and the two support plates are fixedly connected to each other by the connecting plate. The frame 1 is fixed as a whole by welding the base frame 11 and the support frame 12, and a wheel mounting bracket 14 is provided in the support plate. There are four wheels 13. Two wheels 13 are rotatably mounted at the front ends of the two base plates, and the other two wheels 13 are mounted in the support plates by the wheel mounting bracket 14. The two wheels 13 connected to the base plates are movable wheels, and the two wheels 13 connected to the wheel mounting bracket 14 are omnidirectional wheels with limiters.

[0025] Furthermore, in the feeding device for a paint production line provided in this embodiment, the lifting mechanism 2 includes a power drive device 21, a transmission shaft 22, a sprocket 23, a chain 24, and a sliding device.

One end of the chain 24 is fixedly connected to the connecting plate in the support frame 12, and the other end is connected to the rear end of the mounting frame 3. The sliding device is disposed between the mounting frame 3 and the support plate in the support frame 12, and the mounting frame 3 is slidably connected to the support plate in the support frame 12 through the sliding device. Under the action of the power drive device 21, the chain 24 drives the mounting frame 3 to move up and down along the support plate through the sliding device.

[0026] Furthermore, in the feeding device for a paint production line provided in this embodiment, the lifting mechanism 2 has two sets of sliding devices, which are symmetrically arranged between the mounting frame 3 and the support plate.

The support block 25 has a screw hole corresponding to the connecting bolt 27, and the support plate in the support frame 12 has a groove 28 corresponding to the pulley 26. The pulley 26 is disposed in the groove 28, and the connecting bolt 27 passes through the screw hole and is fixedly connected to the pulley 26. A fastening nut 29 is disposed in the connecting bolt 27.

[0027] Furthermore, in the feeding device for a paint production line provided in this embodiment, for ease of operation, the power drive device 21 in the lifting mechanism 2 is a hydraulic jack. Since hydraulic jacks are common power equipment in the prior art, no specific model is detailed; it is sufficient to purchase a model that meets the usage requirements from the existing market. During operation, the foot pedal is used to reciprocate the crank handle, causing the oil pump to continuously pressurize the oil cylinder. The increasing oil pressure in the cylinder forces the piston upward, allowing the chain 24 to drive the sliding device and mounting bracket 3 upward along the support plate, thus achieving height adjustment. When upward movement is not required, simply open the return valve, and the high-pressure oil in the cylinder flows back to the storage chamber. The piston then falls, allowing the mounting bracket 3 to move downward along the support plate, returning to its original position for future use. Additionally, to facilitate moving the frame 1, a rotatable push-pull handle 6 is provided on the outer side of the hydraulic jack, and a hand handle 7 is provided on the rear side of the support plate in the support frame 12.

The hand crank mechanism 5 is set in the mounting frame 3 outside the support mechanism 4. Under the action of the hand crank mechanism 5, the support mechanism 4 can rotate around the support arms 32 in the mounting frame 3.

[0029] Furthermore, in the feeding device for a paint production line provided in this embodiment, the support mechanism 4 includes a support rod 41, a first support ring 42, a second support ring 43, a U-shaped guide ring 44, a positioning plate 45, a connecting bushing 46, and a rotating shaft 47.

Example 2

[0031] This embodiment is based on embodiment 1. In order to facilitate the fixing of the iron drum placed on the positioning plate 45 and avoid shaking during transportation and falling off the support mechanism 4, a feeding device for a paint production line provided in this embodiment is adopted. The positioning plate 45 and the bottom of the support rod 41 are provided with a rotating connection structure. The positioning plate 45 is set with an L-shaped bending structure, and an operating handle 48 that can drive the positioning plate 45 to rotate is also provided at the rear end of the positioning plate 45. Meanwhile, the support mechanism 4 is also equipped with a limiting snap-fit ​​mechanism 49. The limiting snap-fit ​​mechanism 49 includes a snap-fit ​​support plate 491, a limiting snap-fit ​​plate 492, a rotating shaft support seat 493, an operating turntable 494, and a connecting screw 495. The snap-fit ​​support plate 491 is disposed on the top of the support rod 41, and the rotating shaft support seat 493 is disposed on the snap-fit ​​support plate 491. The limiting snap-fit ​​plate 492 is rotatably connected to the snap-fit ​​support plate 491 through the rotating shaft support seat 493. A snap-fit ​​limiting block 496 is also provided at the front end of the limiting snap-fit ​​plate 492, and a connecting screw sleeve 497 corresponding to the connecting screw 495 is provided at the rear end of the limiting snap-fit ​​plate 492. The operating turntable 494 is fixed in the connecting screw 495, and the connecting screw 495 passes through the connecting screw sleeve 497 and can be screwed to the snap-fit ​​support plate 491.

[0032] By rotating the positioning plate 45 using the operating handle 48, the bottom of the iron drum can be limited by the positioning plate 45, which is set with an L-shaped bending structure. The top of the iron drum can be limited by the limiting locking mechanism 49 and the locking limiting block 496 at the front end of the limiting locking plate 492. This can prevent the iron drum from falling off the support mechanism 4 due to loosening during movement and feeding, effectively reducing safety risks.

[0033] like Figure 9 As shown, the feeding device for a paint production line described in this utility model, in practical application, involves transporting an iron drum containing liquid raw materials to the support mechanism 4. The bottom and top of the iron drum are pre-fixed using the positioning plate 45 and the locking limit block 496 at the front end of the limiting plate 492. This prevents the iron drum from falling off the support mechanism 4 due to loosening during movement and feeding, effectively reducing safety risks. Then, the frame 1 is used to transport the iron drum to the reaction vessel in the paint production line where feeding is required. The lifting mechanism 2 moves the mounting frame 3 and the support mechanism 4 upwards along the support frame 12 in the frame 1. After reaching the appropriate height, the hand-cranked mechanism 5 rotates the support mechanism 4, which is rotatably mounted in the mounting frame 3, to an inclined state, thereby pouring the liquid raw materials from the iron drum into the reaction vessel.

[0034] Therefore, the feeding device for a coating production line described in this utility model, with four wheels 13 installed in the frame 1, facilitates the handling of bottled liquids using the movable frame 1. Simultaneously, the support mechanism 4 is rotatably mounted in the mounting frame 3, and the frame 1 is equipped with a lifting mechanism 2 for controlling the mounting frame 3 and a hand crank mechanism 5 for controlling the rotation of the support mechanism 4. Through the cooperation of the lifting mechanism 2 and the hand crank mechanism 5, not only the height of the mounting frame 3 can be adjusted, but also the rotation angle of the support mechanism 4 can be adjusted. Furthermore, since the support rod 41 in the support mechanism 4 has a positioning plate 45 at its bottom and a limiting locking mechanism 49 at its top, the bottled liquid to be fed can be fixed using the positioning plate 45 and the limiting locking mechanism 49. During the feeding process, only the support mechanism 4 needs to be rotated to easily pour the bottled liquid raw material fixed in the support mechanism 4 into the reaction vessel, thereby achieving controllable feeding height and speed, and achieving the goals of safety and labor saving.

[0035] In summary, the feeding device described in this utility model utilizes the principle of existing forklifts. Through the cooperation of the lifting mechanism 2 and the hand crank mechanism 5, the height and angle of the support mechanism 4, which is rotatably installed in the mounting frame 3, can be adjusted. This allows for feeding of materials to reaction vessels of different heights, achieving controllable feeding height and speed. It meets the feeding requirements of coating production lines, achieving both safety and labor-saving goals. Its overall structure is simple, easy to operate, and highly practical, making it suitable for widespread application.
