Description

TECHNICAL FIELD

[0001] The utility model relates to quantitative unloading mechanism technical field, concretely is a kind of hot melt coating quantitative unloading mechanism. BACKGROUND

[0002] In many industrial production fields, such as road marking construction, edge sealing process in furniture manufacturing, carton bonding in packaging industry, hot melt coating is widely used due to its excellent properties. It is solid powder at room temperature, and needs to be heated to a specific temperature to melt during construction, thereby playing the functions of bonding, marking, etc.

[0003] Based on the above, the present inventor found that the following problems exist: The current hot melt coating unloading mechanism lacks a quantitative mechanism. In the context of road marking construction, the amount of hot melt coating needs to be strictly controlled. If too much is unloaded, the thickness of the marking may not be uniform, and the surface may not be smooth, which not only affects the appearance, but also causes the drying time to be prolonged due to excessive thickness, hindering the resumption of normal traffic. On the contrary, if too little is unloaded, it is not possible to form a complete and clear marking, which reduces the visibility and durability of the marking and increases the potential risk of traffic accidents.

[0004] Therefore, in view of the above, the existing structure and deficiencies are improved, and a hot melt coating quantitative unloading mechanism is provided to achieve a more practical value. INVENTION CONTENTS

[0029] Please refer to Figure 1 - Figure 4The upper end of the insulated bucket 301 is fitted with a bucket lid 303, and the upper end of the metering box 401 is fitted with a box lid 405. An insulation layer 310, made of polyurethane, is fixedly installed on the inner wall of the insulated bucket 301. A push handle 305 is fitted on one side of the insulated bucket 301. Universal wheels 2 are fixedly installed at the four corners of the bottom of the base 1. The bucket lid 303 of the insulated bucket 301 reduces heat loss and prevents debris from falling into the mixing bucket 307, affecting the coating quality. The box lid 405 of the metering box 401 prevents dust and other impurities from entering the metering box 401, ensuring precise metering. For accuracy and cleanliness of the coating, the polyurethane insulation layer 310 on the inner wall of the insulated bucket 301 has good heat preservation performance, which can effectively reduce the heat loss inside the insulated bucket 301, reduce energy consumption, maintain the temperature stability of the hot melt coating in the mixing bucket 307, and ensure that the coating always maintains good fluidity.

The universal wheels 2 at the four corners of the bottom of the base 1 make the mechanism move more flexibly and conveniently. The position of the mechanism can be adjusted at any time according to the actual needs of the production site, improving the convenience of production operations.

[0030] Specifically, the working principle of this hot melt coating quantitative feeding mechanism is as follows: The operator moves the mechanism to a suitable position using the push handle 305 and the casters 2 at the four corners of the base 1. During use, the hot melt coating to be processed is placed into the mixing tank 307. The servo motor 312 inside the base 302 starts, driving the stirring rod 304 to rotate and stir the coating, ensuring uniform mixing and preventing sedimentation. The polyurethane insulation layer 310 on the inner wall of the insulation tank 301, combined with the heating jacket 309, reduces heat loss and maintains the temperature of the coating in the mixing tank 307, ensuring its fluidity. Simultaneously, the temperature sensor 308 at the upper end of the inner wall of the mixing tank 307 monitors the coating temperature in real time and provides feedback to control... When the heating jacket 309 is in operation, the uniformly stirred coating is drawn out from the bottom of the mixing tank 307 by the first pump 311 in the bottom tank 302 through the pipeline and transported to the bottom of the metering tank 401. The liquid level sensor 402 on one side of the metering tank 401 monitors the coating liquid level in real time. When the preset amount is reached, the first pump 311 stops transporting. When it is necessary to discharge, the solenoid valve 404 is opened, and the second pump 403 of the metering mechanism 4 starts to transport the coating in the metering tank 401 to the use position through the connecting flange. Throughout the process, the lid 303 of the heat preservation tank 301 and the lid 405 of the metering tank 401 prevent foreign objects from entering, ensuring the quality of the coating and the accuracy of the metering.
