Description

Technical Field

[0001] This utility model relates to the technical field of hot melt adhesive granule production, specifically to an environmentally friendly hot melt adhesive granule production line. Background Technology

[0002] The main function of a hot melt adhesive granule production line is to efficiently and stably produce high-quality hot melt adhesive granules to meet market demand for various hot melt adhesive products.

[0003] like Figure 1 As shown, in existing hot melt adhesive granule production lines, the hot melt adhesive granules are dehydrated by cooling water when passing through conveyor module 1a. Then, auxiliary agents such as wax powder are added to reduce the surface stickiness of the granules. The hot melt adhesive granules are then lifted and vibrated by elevator 2a. Under the action of elevator 2a, the hot melt adhesive granules gradually return from a low temperature to a normal temperature while being evenly mixed with the auxiliary agents such as wax powder. Finally, they are discharged through the outlet of the mixing module. However, because the surface of elevator 2a is exposed, dust from the auxiliary agents such as wax powder will disperse into the surrounding space during the lifting process, leading to a decline in air quality and affecting the health of workers. Furthermore, the hot melt adhesive granules are exposed to outside air, making them susceptible to moisture and affecting their drying properties.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an environmentally friendly hot melt adhesive granule production line that can prevent dust generated during the production and processing of hot melt adhesive granules from drifting in the surrounding environment, thereby improving the air quality near the production line and protecting the respiratory health of workers.

[0006] The purpose of this utility model is achieved as follows:

An inlet is located between the front and rear ends of the feeding pipe, forming a height difference between the inlet and the rear end of the feeding pipe. The inlet of the feeding pipe is connected to the outlet of the conveying module.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 2-4 This environmentally friendly hot melt adhesive granule production line includes a mixing module and a conveying module 1 for conveying hot melt adhesive granules to the mixing module. The mixing module includes a finished product mixer 2, which has a mixing chamber 21. The mixing chamber 21 is equipped with a stirring element 22. The inlet end of the mixing chamber 21 is connected to the conveying module 1 through a feeding pipe 3. The finished product mixer 2 is also equipped with an outlet 23 that allows the hot melt adhesive granules to leave. The hot melt adhesive granules do not need to be exposed to the external environment when leaving the conveying module 1 and entering the mixing module, thus avoiding the dust generated from being dispersed in the surrounding environment, thereby improving the air quality near the production line and protecting the respiratory health of workers. At the same time, the hot melt adhesive granules can avoid contact with air and becoming damp before entering the mixing module.

[0024] The feed end of the mixing chamber 21 is located on its upper side. The rear end of the feeding pipe 3 is connected to the feed end of the mixing chamber 21. The front end of the feeding pipe 3 is connected to the fan 8. The airflow generated by the fan 8 can blow the hot melt adhesive particles into the mixing chamber 21. At the same time, the airflow generated by the fan 8 can also dry the hot melt adhesive particles and improve the dryness of the hot melt adhesive particles.

[0025] A feed inlet 31 is provided between the front end and the rear end of the feeding pipe 3. A height difference is formed between the feed inlet 31 and the rear end of the feeding pipe 3. The feed inlet 31 of the feeding pipe 3 is connected to the discharge end of the conveying module 1, which can make more reasonable use of the external space and reduce the overall height of the equipment.

[0026] Furthermore, a guide plate 311 is connected to the discharge end of the inlet 31 on the side near the blower 8. The guide plate 311 is inclined from top to bottom towards the side away from the blower 8. When the hot melt adhesive particles leave the discharge end of the inlet 31, they flow into the feed pipe 3 at the position corresponding to the front of the blower 8 under the action of the guide plate 311 and gravity. The airflow generated by the blower 8 is difficult to enter the inlet 31 under the action of the guide plate 311. Therefore, the hot melt adhesive particles leaving the discharge end of the inlet 31 are not easy to re-enter the inlet 31. The airflow generated by the blower 8 will not obstruct the hot melt adhesive particles from entering the feed pipe 3. The airflow generated by the blower 8 can drive the hot melt adhesive particles to be conveyed along the feed pipe 3 towards the finished product mixer 2.

[0027] Furthermore, a filter element 4 for filtering dust is provided between the rear end of the feeding pipe 3 and the feed end of the mixing chamber 21, reducing the chance of dust entering the mixing chamber 21 and improving the processing quality of the mixing chamber 21.

[0028] Furthermore, the lower side of the filter element 4 is connected to the feed end of the mixing chamber 21, the upper side of the filter element 4 is provided with a dust adsorption device 41, and an air inlet 42 is provided between the upper and lower sides of the filter element 4. The air inlet 42 is connected to the rear end of the feeding pipe 3.

[0029] Furthermore, the axial direction of the air inlet 42 is offset from the central axis of the filter element 4, and the cavity inside the filter element 4 is funnel-shaped with a wider top and a narrower bottom. When the airflow carries the hot melt adhesive particles into the filter element 4, the airflow will move along the inner wall of the filter element 4 to form a rotating airflow. The rotating airflow can make the lighter dust move upward to the dust adsorption device 41, and the heavier hot melt adhesive particles will move downward to the mixing chamber 21.

[0030] Furthermore, the upper side of the finished product mixer 2 is provided with an auxiliary agent adding device 5 for adding auxiliary agents to the mixing chamber 21 from the outside, which makes it convenient for users to add auxiliary agents such as wax powder to the mixing chamber 21. After the auxiliary agents such as wax powder are fully mixed with the hot melt adhesive particles, the stickiness of the hot melt adhesive particles can be reduced, and the hot melt adhesive particles can be prevented from forming clumps.

[0031] Furthermore, the additive addition device 5 includes an additive inlet 51 and an additive outlet 52. The additive inlet 51 is located on the upper outer side of the finished product mixer 2 and extends into the mixing chamber 21. A feeding screw (not shown in the figure) is provided between the additive inlet 51 and the additive outlet 52. The feeding screw is connected to a feeding motor 53, which can drive the feeding screw to rotate. The precise addition of the additive can be achieved by preset the running time of the feeding motor 53, thereby improving the automation level of the equipment.

[0032] Furthermore, the discharge port 23 of the finished product mixer 2 is equipped with a movable baffle 6, which is connected to an electric drive device 61. The electric drive device 61 pushes the movable baffle 6 to reciprocate, thereby opening or closing the discharge port 23 of the finished product mixer 2.

[0033] Furthermore, an electronic scale 7 is installed below the discharge port 23 of the finished product mixer 2. The electronic scale 7 is electrically connected to an electronic control device, which is electrically connected to the electric drive device 61.

[0034] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
