Description

Technical Field

[0001] This utility model relates to the field of automatic material dispensing technology, and in particular to an automatic material dispensing device for dye barrels. Background Technology

[0002] Automatic dye barrel unloading device is a key piece of equipment used in the chemical and printing and dyeing industries to achieve automated dye transfer. Its core function is to lift heavy dye barrels to a specified height and control the barrel to precisely tilt and pour viscous dyes into downstream containers.

[0003] Current dye barrel pouring devices face two major technical bottlenecks: First, insufficient precision in tilting angle control leads to splashing and residue problems. Mainstream equipment uses hydraulic cylinders or chain-driven tilting mechanisms, with angle adjustment relying on rough increments of limit switches, such as 30°, 60°, and 90°. Due to the poor flowability of viscous dyes, precise control of the pouring rate and final tilt angle is necessary, requiring an angle greater than 90° to achieve complete drainage. However, existing mechanical structures are prone to inertial shaking at the end of pouring, causing dye splashing; simultaneously, insufficient rigidity causes barrel vibration, resulting in a residue rate as high as 8%-12%. Second, barrel opening seal failure leads to contamination and raw material waste: At the initial moment of pouring, viscous dye, under the influence of gravity, flows outward along the lower semicircle of the barrel opening, causing contamination of the barrel. Industry data shows that the average leakage during a single pouring process reaches 0.5-1.2 liters, contaminating the barrel and equipment surface, increasing cleaning costs and wasting valuable dyes.

[0004] Therefore, this application provides an automatic dispensing device for dye barrels to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an automatic pouring device for dye barrels, which solves the problems of inaccurate tilting angle control of existing automatic pouring devices, leading to splashing and residue of viscous dyes, and directional leakage and pollution caused by lack of sealing at the barrel opening.

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic dispensing device for dye barrels, including a lifting frame, a vertically movable lifting platform on the lifting frame, the lifting platform including a horizontal load plate and a vertical baffle, a rotary motor on the horizontal load plate, and the output shaft of the rotary motor horizontally passing through the vertical baffle and having a first gear.

[0007] The outer wall of the lifting platform is equipped with a rotatable barrel rack via a pivot. The barrel rack is used to fix the dye barrels. A second gear is rigidly fixed on the outer wall of the barrel rack. The first gear and the second gear mesh with each other to form a reduction gear pair. The first gear is a full circular gear. The second gear is a partially arc-shaped gear with the pivot as its center, and its arc range is 95-120°. The pitch circle radius of the second gear is larger than that of the first gear.

[0008] A funnel is installed at the top front end of the drum rack, with the inlet of the funnel corresponding to the opening of the dye drum fixed on the drum rack. A rubber sealing gasket is installed around the inlet end of the funnel, extending around the inner wall of the inlet end of the funnel to form a 180° arc-shaped sealing area. This sealing area is located at the lower half-circumference of the opening of the dye drum when the drum rack is tilted and overturned, and is used to tightly fit and seal the outer wall of the opening of the dye drum to prevent viscous dye from leaking.

[0009] A further improvement of this utility model is that: a lifting motor is installed on one side of the bottom of the lifting frame, the lifting motor is connected to a vertical lead screw through a pulley, and the top of the lead screw passes vertically through the center of the top of the lifting frame; a threaded through hole is provided in the center of the lifting platform, and the threaded through hole and the middle of the lead screw form a threaded engagement.

[0010] A further improvement of the present invention is that the second gear is fixed to the outer wall of the barrel frame by a connecting piece, the connecting piece being an L-shaped metal plate, the first right-angled side of the connecting piece being fixed to the outer wall of the barrel frame, and the second right-angled side being fixed to the hub end face of the second gear.

[0011] A further improvement of this utility model is that an integrally formed stop block is provided on the barrel rack, the bottom surface of the stop block is flush with the edge of the opening of the dye barrel, and the stop block is used to lock and fix the edge of the opening of the dye barrel to prevent the dye barrel from slipping when it is tilted.

[0012] A further improvement of this utility model is that the rubber sealing gasket is made of solvent-resistant elastic rubber; the rubber sealing gasket has a sealing lip that extends toward the outer wall of the dye barrel opening and is pressed at an angle.

[0013] A further improvement of this utility model is that the funnel is fixedly connected to the barrel frame by bolts.

[0014] A further improvement of this utility model is that the central axis of the funnel inlet coincides with the central axis of the dye barrel opening fixed on the barrel rack.

[0015] A further improvement of this utility model is that the inner cavity of the funnel is a smooth curved surface.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides an automatic pouring device for dye barrels. This device, through a reduction gear pair consisting of a first gear and a second gear, achieves rigid transmission and precise angle control during the pouring process. Compared to the coarse-grained tilting of hydraulic cylinders and chain traction, this design eliminates inertial swaying at the end of the pouring process, preventing viscous dye from splashing. Simultaneously, the >90° stroke of the arc-shaped gear ensures the barrel is completely inverted, addressing the industry pain point of a high residue rate of 8%-12% and significantly improving dye transfer efficiency.

[0018] 2. This utility model provides an automatic dispensing device for dye barrels. This device forms a 180° lower semi-circular directional sealing area at the funnel inlet end using a rubber sealing gasket, combined with an inclined pressing structure for the sealing lip, achieving source-level leakage prevention for viscous dyes. Addressing the leakage problem caused by directional flow in the lower half of the barrel opening, this device covers the area with the greatest leakage risk with the smallest sealing area, tightly conforming to the barrel wall curve at the moment of dispensing, eliminating dye leakage and pollution, and significantly reducing cleaning costs and material waste.

[0019] 3. This utility model provides an automatic dispensing device for dye barrels. This device achieves a compact integration of the power system and the actuator through an integrated structure of the horizontal load plate and vertical baffle of the lifting platform, and a layout where the output shaft of the rotary motor horizontally passes through the baffle. While ensuring the meshing accuracy of the gear pair, it avoids the bulky equipment problem of traditional gear-driven solutions, making the device suitable for narrow workshop spaces. The vertical baffle, as the core load-bearing unit, eliminates transmission instability caused by barrel frame vibration, ensuring the continuity of the dispensing action.

[0020] 4. This utility model provides an automatic dispensing device for dye barrels. The device achieves stable clamping and fluid guidance optimization of the dye barrel through the structure of the integrally molded baffle and barrel frame, as well as the smooth curved surface structure of the funnel cavity. The baffle immediately engages with the edge of the barrel opening to prevent slippage and solves the problem of barrel displacement during the pouring process. The curved surface of the funnel guides the viscous dye to flow in a directional manner, eliminating residues on the wall and forming a double guarantee against leakage with the sealing gasket.

[0035] The present invention will be further explained below with reference to specific embodiments.

[0036] like Figures 1 to 9 As shown in the figure, this embodiment provides an automatic dispensing device for dye barrels, including a lifting frame 1. A lifting motor 2 is installed on one side of the bottom of the lifting frame 1. The lifting motor 2 is connected to a vertical lead screw 4 via a pulley 3. The top of the lead screw 4 vertically passes through the center of the top of the lifting frame 1. A vertically movable lifting platform 5 is provided on the lifting frame 1. The center of the lifting platform 5 has a threaded through hole, which forms a threaded engagement with the middle of the lead screw 4. When the lifting motor 2 drives the lead screw 4 to rotate, it drives the lifting platform 5 to rise and fall smoothly in the vertical direction to accommodate receiving containers of different heights. The lifting platform 5 includes a horizontal load plate 6 and a vertical baffle 7 fixedly connected to it. A rotary motor 9 is installed on the horizontal load plate 6. The output shaft of the rotary motor 9 horizontally passes through the vertical baffle 7 and is fixedly installed with a first gear 10. The horizontal load plate 6 provides a stable bearing surface for the lifting mechanism, and the vertical baffle 7 serves as a rigid support base for the gear transmission system to ensure that the power transmission is unbiased. Both the lifting motor 2 and the rotary motor 9 are existing products. Through the integrated design of the lifting screw 4 and the load-bearing vertical baffle 7, the device height can be precisely adjusted and the power system can be torsional stable, providing a solid foundation for the subsequent tilting action.

[0037] like Figures 4 to 9As shown, the vertical baffle 7 of the lifting platform 5 is connected to a rotatable drum frame 14 via a horizontal rotating shaft 13. The drum frame 14 is used to fix the dye drums 8. The outer wall of the drum frame 14 is rigidly fixed to the second gear 11 via an L-shaped connecting piece 12. The first right-angle side of the connecting piece 12 is welded to the side wall of the drum frame 14, and the second right-angle side is welded to the hub end face of the second gear 11, ensuring that the gear rotates synchronously with the drum frame 14 without displacement deviation. The first gear 10 and the second gear 11 mesh with each other to form a reduction gear pair. The first gear 10 is a full-circle driving gear, and the second gear 11 is a partially arc-shaped gear whose center coincides with the rotating shaft 13. Its arc range is 95° to 120°, and the pitch circle radius of the second gear 11 is larger than that of the first gear 10, forming a reduction and torque increase transmission. This design allows the drum frame 14 to rotate at a controllable low speed under the drive of the motor. The arc-shaped gear limits the tilting angle to a state greater than 90° to a near-vertical inverted state, thoroughly draining residual dye. The reduction arc gear transmission system combines the advantages of compact layout and precise stroke control, fundamentally solving the problem of splashing and residue at the end of pouring viscous dyes.

[0038] like Figures 6 to 9 As shown, a funnel 16 is fixedly installed at the top front end of the drum frame 14. The inner cavity of the funnel 16 is a smooth curved surface. It is connected to the drum frame 14 by bolts, and its inlet axis coincides with the axis of the dye drum 8's opening. A solvent-resistant rubber sealing gasket 17 is provided on the inner circumference of the inlet end of the funnel 16. The gasket 17 forms a 180° lower semi-circular arc sealing area along the edge of the inlet and has a sealing lip that extends obliquely towards the outer wall of the dye drum 8's opening. When the drum frame 14 is tilted, the sealing lip tightly presses against the outer wall of the lower semi-circular circumference of the drum opening, directionally blocking the flow path of viscous dye along the drum wall. An integrally formed baffle 15 is welded to the inner side of the drum frame 14. The bottom surface of the baffle 15 is flush with the edge of the dye drum 8's opening, locking the edge of the opening at the moment of tilting to prevent the drum from slipping. The funnel 16 seal and the baffle 15 work together to achieve maximum leakage protection with minimal sealing area, ensuring that the viscous dye flows directionally along the curved surface of the funnel 16 throughout the process, completely eliminating drum body contamination and raw material waste.

[0039] This utility model also provides the operating principle of an automatic dispensing device for dye barrels:

[0040] The operator first inserts the dye barrel 8 into the barrel rack 14, ensuring that the edge of the dye barrel 8 is tightly fitted against the inner stop block 15 of the barrel rack 14 for secure locking. The lifting motor 2 is then started, driving the lead screw 4 to rotate via the pulley 3, which in turn lifts the lifting platform 5 vertically along the lifting frame 1 to the height of the receiving container. Subsequently, the rotating motor 9 drives the first gear 10 to mesh with the partially arc-shaped second gear 11 on the barrel rack 14. Under deceleration and torque-increasing transmission, the barrel rack 14 is pushed to rotate around the shaft 13 at a controllable speed. When the arc stroke of the second gear 11 reaches 95°-120°, the dye barrel 8 is completely inverted, and the viscous dye flows into the funnel 16 along the barrel opening. At this time, the 180° rubber sealing gasket 17 at the inlet of the funnel 16 tightly presses against the lower semicircular outer wall of the barrel opening through the inclined sealing lip, blocking the dye leakage path along the barrel wall. The dye is then guided through the smooth curved surface of the funnel 16's inner cavity to the downstream container. After pouring, the rotating motor 9 reverses the gear pair to reset the barrel rack 14, and the lifting platform 5 descends to its initial position, completing the work cycle.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
