Description

Technical Field

[0001] This utility model relates to the field of material unloading cart technology, and in particular to a semi-automatic material unloading cart for high-viscosity liquid adhesive. Background Technology

[0002] In industrial production, high-viscosity liquid adhesives are a class of colloidal fluid materials with high viscosity and poor flowability at room temperature. Examples include silicone, epoxy resin, and sealants. These materials are widely used in chemical, electronic packaging, and automotive manufacturing industries. The production process often requires transfer and feeding operations, typically using 200L open-face iron drums for transfer. Currently, the traditional manual pouring method is still used for high-viscosity liquid adhesives, which presents the following problems:

[0003] 1. Due to the high viscosity of the liquid adhesive, the pouring process is very slow. Manual intervention has limited effect during the pouring process, and it takes a long time to completely empty the material in the container, which seriously affects production efficiency. Near the end of the pouring process, the high viscosity causes a "stringing" phenomenon, which not only prolongs the waiting time but also causes raw material residue and increases material waste.

[0004] 2. When high-viscosity liquid adhesive needs to be applied to multiple locations, multiple drum-tilting carts must be equipped, which increases both the labor intensity of employees and the equipment investment cost. Manually pushing iron drums and repeatedly turning them over can easily lead to employee fatigue.

[0005] 3. The "stringy" liquid drips onto the ground or equipment, causing small-scale environmental pollution and increasing the difficulty of cleaning.

[0006] Therefore, the current process of discharging high-viscosity liquid adhesives suffers from problems such as low efficiency, high cost, pollution risk, and insufficient automation. There is an urgent need for a semi-automatic discharging cart for high-viscosity liquid adhesives that integrates mobility, efficient material discharge, and stable sealing. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a semi-automatic dispensing cart for high-viscosity liquid adhesives that can accelerate the feeding efficiency of high-viscosity liquid adhesives, reduce the number of tipping carts and investment when feeding at multiple points, reduce liquid "stringing", improve the environment, increase automation, and reduce the labor intensity of employees.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A semi-automatic unloading cart for high-viscosity liquid adhesive includes a battery-powered handcart and a feeding cylinder, as well as a frame, two tilting hydraulic cylinders, a multi-stage hydraulic cylinder, and a pressure plate;

[0010] The frame includes two vertically arranged support rods and a horizontally arranged rotating shaft. The lower end of the support rods is fixedly connected to the electric handcart. The two ends of the rotating shaft are fixedly connected to the upper ends of the two support rods respectively. A bushing is rotatably installed on the rotating shaft. An upper cylinder hoop is fixedly installed on the feeding cylinder. The bushing and the upper cylinder hoop are fixedly connected by several connecting plates.

[0011] A lower cylinder hoop is fixedly installed on the feeding cylinder, and pins are fixedly installed on both sides of the lower cylinder hoop. The outer end of the telescopic rod of the tilting hydraulic cylinder is rotatably engaged with the pins. A round shaft is fixedly installed on the outer side of the support rod, and the cylinder body of the tilting hydraulic cylinder is rotatably engaged with the round shaft.

[0012] The feeding cylinder is a cylindrical body with both ends connected. A cylinder seat is fixedly installed at the lower end of the cylinder body. The cylinder body of the multi-stage hydraulic cylinder is fixedly installed on the cylinder seat. The end of the telescopic rod of the multi-stage hydraulic cylinder is fixedly connected to the pressure plate. A sealing structure is provided between the pressure plate and the feeding cylinder.

[0013] Thus, this application integrates components such as a battery-powered trolley, frame, tilting hydraulic cylinder, multi-stage hydraulic cylinder, and pressure plate to construct a semi-automatic material unloading structure that integrates "transportation-tilting-pushing." The battery-powered trolley enables electrified transportation of high-viscosity liquid adhesive, reducing the intensity of manual handling. Two tilting hydraulic cylinders symmetrically connect the support rod and the feeding cylinder, and, in conjunction with the rotating structure of the shaft and bushing, can stably drive the feeding cylinder to flexibly tilt and precisely control the unloading angle. The multi-stage hydraulic cylinder, fixed by cylinder seats, pushes the pressure plate to move within the feeding cylinder, which runs through both ends, and, combined with a sealing structure, achieves efficient pushing of high-viscosity materials. The overall structure solves the problems of laborious transportation, unstable tilting, and low pushing efficiency in traditional unloading methods, realizing automation and high efficiency in the unloading process of high-viscosity liquid adhesive.

[0014] Preferably, the sealing structure includes two pressure plate sealing rings, the pressure plate has two circumferential grooves, the inner side of the pressure plate sealing ring is located in the circumferential groove, and the outer side of the pressure plate sealing ring is pressed and fitted against the side wall of the feeding cylinder.

[0015] Preferably, the pressure plate has a through hole, the end of the telescopic rod of the multi-stage hydraulic cylinder has a threaded hole, and the pressure plate and the telescopic rod of the multi-stage hydraulic cylinder are fixedly connected by bolts.

[0016] Preferably, the battery-powered handcart is equipped with an oil receiving tray, which has an oil receiving groove with its opening facing upwards.

[0017] Preferably, the cylinder seat has a cross-shaped structure, and the cylinder body of the multi-stage hydraulic cylinder is positioned directly opposite the center of the cylinder seat.

[0018] In summary, this application has the beneficial effects of accelerating the feeding efficiency of high-viscosity liquid adhesives, reducing the number of drum tippers and investment when feeding at multiple points, reducing liquid "stringing", improving the environment, increasing automation, and reducing the labor intensity of employees.

[0023] like Figure 1-3 As shown, a semi-automatic unloading cart for high-viscosity liquid adhesive includes a battery-powered handcart 1 and a feeding cylinder 2, as well as a frame, two tilting hydraulic cylinders 3, a multi-stage hydraulic cylinder 4, and a pressure plate 5;

[0024] The frame includes two vertically arranged support rods 6 and a horizontally arranged rotating shaft 7. The lower end of the support rod is fixedly connected to the electric handcart, and the two ends of the rotating shaft are respectively fixedly connected to the upper ends of the two support rods. A bushing 8 is rotatably installed on the rotating shaft, and an upper cylinder hoop 9 is fixedly installed on the feeding cylinder. The bushing and the upper cylinder hoop are fixedly connected by several connecting plates 10.

[0025] A lower cylinder hoop 11 is fixedly installed on the feeding cylinder, and pins 12 are fixedly installed on both sides of the lower cylinder hoop. The outer end of the telescopic rod of the tilting hydraulic cylinder is rotatably engaged with the pins. A round shaft 13 is fixedly installed on the outer side of the support rod, and the cylinder body of the tilting hydraulic cylinder is rotatably engaged with the round shaft.

[0026] The feeding cylinder is a cylinder with both ends connected. A cylinder seat 14 is fixedly installed at the lower end of the cylinder. The cylinder body of the multi-stage hydraulic cylinder is fixedly installed on the cylinder seat. The end of the telescopic rod of the multi-stage hydraulic cylinder is fixedly connected to the pressure plate. A sealing structure is provided between the pressure plate and the feeding cylinder.

[0027] Thus, this application integrates components such as a battery-powered trolley, frame, tilting hydraulic cylinder, multi-stage hydraulic cylinder, and pressure plate to construct a semi-automatic material unloading structure that integrates "transportation-tilting-pushing." The battery-powered trolley enables electrified transportation of high-viscosity liquid adhesive, reducing the intensity of manual handling. Two tilting hydraulic cylinders symmetrically connect the support rod and the feeding cylinder, and, in conjunction with the rotating structure of the shaft and bushing, can stably drive the feeding cylinder to flexibly tilt and precisely control the unloading angle. The multi-stage hydraulic cylinder, fixed by cylinder seats, pushes the pressure plate to move within the feeding cylinder, which runs through both ends, and, combined with a sealing structure, achieves efficient pushing of high-viscosity materials. The overall structure solves the problems of laborious transportation, unstable tilting, and low pushing efficiency in traditional unloading methods, realizing automation and high efficiency in the unloading process of high-viscosity liquid adhesive.

[0028] Specifically, the existing structure of the battery-powered handcart, also known as an electric trailer or electric flatbed cart, is a commonly used transportation vehicle. A frame is mounted on the handcart to provide a base for the feeding cylinder. The feeding cylinder is typically a 200L metal cylinder, a commonly used container. The feeding cylinder is designed with both ends open to avoid air pressure issues when the pressure plate moves. The multi-stage hydraulic cylinder generally uses a three-stage cylinder with a pressure of 80 MPa. Of course, when selecting a multi-stage hydraulic cylinder, the appropriate cylinder size is chosen based on the viscosity of the high-viscosity liquid adhesive; the higher the viscosity, the larger the hydraulic cylinder. A sealing structure design prevents leakage of the high-viscosity liquid adhesive from the gap between the pressure plate and the feeding cylinder. When loading the high-viscosity liquid adhesive, the extension rod of the multi-stage hydraulic cylinder is in a retracted state, and the pressure plate is located at the bottom of the feeding cylinder. The high-viscosity liquid adhesive is poured into the feeding cylinder and received by the pressure plate. After the feeding cylinder is tilted, when the high-viscosity liquid adhesive needs to be poured out, the telescopic rod of the multi-stage hydraulic cylinder is in an extended state, pushing the pressure plate to move the high-viscosity liquid adhesive outward, enabling the high-viscosity liquid adhesive to be fed out and accelerating the feeding efficiency. In multi-point feeding, the structural design of this application utilizes a battery-powered handcart for electric transport, reducing the number of tipping carts, reducing investment, and also reducing "stringing" issues, improving the environment; it also increases automation and reduces the labor intensity of employees. After feeding is completed, the pressure plate and feeding cylinder reset, and personnel can pull the battery-powered handcart away to prepare more material for the next pouring point, repeating the process efficiently.

[0029] Of course, the electric handcart is equipped with hydraulic components such as a hydraulic pump station, solenoid valves, and valve seats. The multi-stage hydraulic cylinders and the tilting hydraulic cylinders are each connected to two pipelines: an inlet pipe and a return pipe, both of which are high-pressure hoses. Solenoid valves are installed on both the inlet and return pipes and connected to the hydraulic pump station. Specifically, the electric handcart and its support rods are hollowed out to facilitate the passage of the inlet and return pipes.

[0030] A controller is installed on the electric handcart, which is connected to the solenoid valve and the vehicle body controller of the electric handcart and is equipped with control buttons to facilitate the control of the overall operation.

[0031] In practice, the sealing structure includes two pressure plate sealing rings 15. The pressure plate has two annular grooves in its circumference. The inner side of the pressure plate sealing ring is located in the annular groove, and the outer side of the pressure plate sealing ring is pressed and fitted against the side wall of the feeding cylinder.

[0032] In this way, the sealing structure of the double pressure plate sealing ring is fixed in the annular groove by two sealing rings, which are pressed and adhered to the side wall of the feeding cylinder, forming a double sealing barrier. This design significantly improves the sealing performance between the pressure plate and the feeding cylinder: on the one hand, it prevents high-viscosity liquid adhesive from leaking from the gap between the pressure plate and the cylinder wall during the feeding process, ensuring that all material is pushed to the outlet and improving material utilization; on the other hand, it allows the high-viscosity liquid adhesive to be pushed outward during feeding, reducing residue on the side wall of the cylinder. The outer side of the pressure plate sealing ring can slide against the side wall of the feeding cylinder, making it easy to replace after wear. At the same time, the double sealing ring structure also allows the pressure plate to move along the axis of the feeding cylinder, improving the reliability of the movement.

[0033] In practice, the pressure plate has a through hole 16, and the end of the telescopic rod of the multi-stage hydraulic cylinder has a threaded hole. The pressure plate and the telescopic rod of the multi-stage hydraulic cylinder are fixedly connected by bolts.

[0034] In this way, the connection between the pressure plate and the telescopic rod of the multi-stage hydraulic cylinder, secured by bolts, features a stable connection and reliable force transmission. This ensures that the thrust of the telescopic rod is fully transmitted to the pressure plate, meeting the driving force requirements for pushing high-viscosity liquid adhesives. Simultaneously, the bolted connection facilitates the installation, disassembly, and maintenance of the pressure plate: when the pressure plate or sealing ring needs replacement due to wear, the bolts can be quickly removed for inspection, reducing maintenance difficulty and downtime, and extending the effective operating time of the equipment.

[0035] In practice, an oil receiving tray 17 is placed on the battery-powered handcart, and the oil receiving tray has an oil receiving groove with its opening facing upward.

[0036] In this way, the oil receiving tray and upward-opening oil trough structure on the battery-powered handcart can catch high-viscosity liquid adhesives or hydraulic oil generated due to equipment failure (such as seal failure or pipeline leakage), preventing leaks from dripping directly onto the ground or other parts of the equipment. This not only reduces material waste and environmental pollution, but also simplifies cleaning, allowing leaks to be collected and treated centrally, maintaining a clean working environment, and protecting other equipment components from corrosion or contamination by leaks, thus extending the overall service life of the equipment.

[0037] In practice, the cylinder seat has a cross-shaped structure, and the cylinder body of the multi-stage hydraulic cylinder is positioned directly opposite the center of the cylinder seat.

[0038] In this way, the "+" shaped cylinder seat structure provides stable support for the multi-stage hydraulic cylinders through symmetrically distributed support arms. This effectively disperses the reaction force generated during cylinder operation, preventing deformation of the cylinder seat due to uneven stress. The cylinder body of the multi-stage hydraulic cylinder is positioned directly opposite the center of the cylinder seat, ensuring that the force axis of the cylinder is aligned with the axis of the feeding cylinder. This prevents the pressure plate from tilting due to uneven load during movement, ensuring that the pressure plate moves vertically along the inner wall of the feeding cylinder. This further improves the stability and uniformity of the high-viscosity liquid adhesive delivery process and reduces mechanical wear caused by uneven load.

[0039] The operating principle includes the following steps:

[0040] 1. The feeding cylinder axis is in a vertical position, the telescopic rod of the multi-stage hydraulic cylinder is in a retracted position, and the personnel pull the battery-powered handcart to mix the high-viscosity liquid adhesive into the feeding cylinder. After that, the personnel pull the electric handcart to the feeding station.

[0041] 2. The extension rod of the tilting hydraulic cylinder extends, driving the feeding cylinder to rotate around the shaft with the help of the bushing, thus tilting the feeding cylinder. After tilting to the correct position, the extension rod of the multi-stage hydraulic cylinder extends, driving the pressure plate to move. The pressure plate pushes the high-viscosity liquid adhesive outward to achieve feeding. After feeding is completed, the extension rod of the multi-stage hydraulic cylinder retracts and resets, and the extension rod of the tilting hydraulic cylinder retracts and resets, respectively driving the pressure plate and the feeding cylinder to reset.

[0042] 3. Repeat steps 1 and 2 to achieve multi-station material preparation, and use electric handcarts for electric transportation to reduce the number of tippers and reduce investment.

[0043] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
