Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive processing, and in particular to a hot melt adhesive processing thermal circulation device. Background Technology

[0002] Hot melt adhesive is a type of malleable adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. It is highly favored due to its solid nature, ease of packaging, transportation, and storage; solvent-free, pollution-free, and non-toxic properties; simple production process; high added value; strong bonding strength; and fast processing speed. In hot melt adhesive processing, the prepared raw materials are added to a reaction vessel, heated to melt, and stirred evenly. The melted adhesive in the reaction vessel is then cooled to a certain temperature and fed into a running extruder. After extrusion, cooling, and slitting, it becomes hot melt adhesive.

[0003] The prior art patent application with publication number CN213919215U describes a method that uses an oil tank, oil pump, first tee connector, first oil inlet pipe, second oil inlet pipe, sealing ring, jacket, first heating rod, second heating rod, first oil outlet pipe, second oil outlet pipe, second tee connector, motor, rotating shaft, and stirring blades to circulate and heat the heat transfer oil around the tank, ensuring uniform melting of the hot melt adhesive raw materials. The heat transfer oil is added to the oil tank, pressurized by the oil pump, and then diverted through the first tee connector. The oil enters the jacket through the first and second inlet pipes. A sealing ring prevents oil leakage at the interface. The two inlet pipes allow the heat transfer oil to enter the jacket more evenly. After entering the jacket, the heat transfer oil can be further heated by the first and second heating rods to improve efficiency. Finally, the heat transfer oil flows back to the oil tank through the first and second outlet pipes to complete the circulation, making the heat transfer oil to the tank body more even. At the same time, the motor is started, which drives the rotating shaft, which drives the stirring blades to stir the hot melt adhesive material in the tank, making the material heated more evenly.

[0004] However, current heat circulation devices heat the tank by adding hot oil inside and circulating it. When this method is used to circulate the oil on the tank, the surface temperature of the tank will rise, and the heated surface of the tank cannot be kept warm.

[0005] Therefore, it is necessary to provide a thermal circulation device for hot melt adhesive processing to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a thermal circulation device for hot melt adhesive processing provided by this utility model; Figure 2 for Figure 1 A three-dimensional structural schematic diagram of the heat circulation device from a first-view perspective; Figure 3for Figure 1 A three-dimensional structural schematic diagram of the heat circulation device from a second perspective; Figure 4 for Figure 3 The enlarged schematic diagram of part A is shown. A hot melt adhesive processing thermal circulation device includes: Tank body 1, cavity 2, insulation pad 6, heating assembly 3, conveying assembly 7, and filling device 8; The cavity 2 is formed inside the tank body 1; The heat insulation pad 6 is disposed on the surface of the tank body 1; The heating component 3 is disposed on the surface of the heat preservation pad 6. The heating component 3 includes a plurality of heating rods 31, a first connecting line 32 and a second connecting line 33. The plurality of heating rods 31 are respectively disposed on the surface of the heat preservation pad 6. The first connecting line 32 is connected between the plurality of heating rods 31. The second connecting line 33 is connected to one side of the first connecting line 32. The conveying assembly 7 is disposed on the surface of the tank 1; The filling device 8 is located on one side of the conveying assembly 7.

[0018] One end of the second connecting line 33 is connected to the controller 5.

[0019] The conveying assembly 7 includes two L-shaped conveying pipes 71, two connectors 72, and two arc-shaped pipes 73. The two L-shaped conveying pipes 71 are respectively connected to the surface of the tank body 1, the two connectors 72 are respectively connected to one end of the two L-shaped conveying pipes 71, and the two arc-shaped pipes 73 are connected between the two connectors 72.

[0020] The filling device 8 includes a housing 81, a pump body 82, and two filling pipes 83. The pump body 82 is mounted on the surface of the housing 81, and the two filling pipes 83 are respectively connected to the input end and the output end of the pump body 82.

[0021] A fixing sleeve 4 is provided between each of the multiple heating rods 31 and the heat insulation pad 6.

[0022] A circulation pipe 9 is connected between the tank body 1 and the box body 81, and a tank cover 10 is provided on the top of the tank body 1.

[0023] During the circulation process, the controller 5 monitors the temperature inside the tank 1 in real time. When the temperature is lower than the set temperature, the controller 5 increases the power of the heating rod 31 and increases the speed of the pump body 82 to accelerate the circulation speed of the heat transfer oil. When the temperature is higher than the set temperature, the controller 5 reduces the power of the heating rod 31 and reduces the speed of the pump body 82 to ensure that the temperature inside the tank 1 remains stable within the set range.

[0024] A fixing sleeve 4 is installed on the surface of the heat insulation pad 6. The fixing sleeve 4 is made of high temperature resistant rubber. The number of the fixing sleeves is the same as that of the heating rods 31, and they need to be arranged according to the principle of uniform distribution. The fixing sleeve 4 is connected and fixed to the heat insulation pad 6 through a snap-fit ​​structure.

[0025] Insert multiple heating rods 31 into the corresponding fixing sleeves 4 to ensure that the heating rods 31 fit tightly with the fixing sleeves 4 without any looseness. The power of the heating rods 31 can be selected according to the volume of the tank 1.

[0026] Multiple heating rods 31 are connected in series using the first connecting wire 32. The connecting wire must be made of high-temperature resistant silicone wire. When connecting, the insulation layer at the end of the wire must be stripped, and the wire must be fixed to the terminal of the heating rod 31 through the terminal block to ensure good contact and no risk of poor connection.

[0027] Connect one end of the second connecting line 33 to the middle node of the first connecting line 32, and connect the other end to the output terminal of the controller 5. The controller 5 should be a model with temperature setting, display and overload protection functions (such as a PLC controller). After the connection is completed, an insulation test is required.

[0028] One end of each of the two L-shaped delivery pipes 71 is welded and fixed to the oil inlet and outlet ports on the side wall of the tank 1. The weld joints need to be ground to ensure that there are no burrs or leaks. Then, high-temperature resistant sealing tape is wrapped around the weld joints to further improve the sealing performance.

[0029] Connect the other end of the L-shaped conveying pipe 71 to the arc-shaped pipe 73 using connector 72. Connector 72 is a threaded structure. When connecting, apply high-temperature resistant sealant to the thread and then tighten connector 72 with L-shaped conveying pipe 71 and arc-shaped pipe 73 with a wrench to ensure a firm connection.

[0030] Place the housing 81 of the filling device 8 on a bracket on one side of the tank 1, and fix the pump body 82 to the top of the housing 81 with bolts. The pump body 82 is a gear pump, and its flow rate must match the volume of the tank 1.

[0031] Two filling pipes 83 are connected to the input and output ends of the pump body 82 respectively. One end of the filling pipe 83 is fixed to the interface of the pump body 82 by a clamp, and the other end is connected to the oil outlet of the housing 81 and the middle interface of the arc pipe 73 respectively. After the connection is completed, the sealing of each interface needs to be checked.

[0032] Finally, connect the two ends of the circulation pipe 9 to the oil return port of the tank body 1 and the oil return port of the box body 81 respectively, using threaded connection and sealing with sealant. At the same time, put the tank cover 10 on the top of the tank body 1, and set a sealing ring between the tank cover 10 and the tank body 1. Fix the tank cover 10 with buckles.

[0033] The working principle of the hot melt adhesive processing heat circulation device provided by this utility model is as follows: Start the pump body 82. The pump body 82 starts working and delivers the heat transfer oil in the tank 81 to the arc-shaped pipe 73 through the filling pipe 83, and then to the cavity 2 inside the tank 1 through the L-shaped conveying pipe 71. The heat transfer oil flows in the cavity 2 and heats the hot melt adhesive material inside the tank 1. At the same time, the controller 5 controls the heating rod 31 to start, and the heating rod 31 begins to heat up. The heat is transferred to the surface of the tank 1 through the insulation pad 6 to provide auxiliary heating to the tank 1, ensuring that the surface temperature of the tank 1 is consistent with the internal temperature and reducing heat loss.

[0034] After the heat transfer oil is heated in the cavity 2, it flows back to the box 81 through the circulation pipe 9, forming a heat transfer oil circulation.

[0035] Compared with related technologies, the hot melt adhesive processing heat circulation device provided by this utility model has the following beneficial effects: This utility model provides a heat circulation device for hot melt adhesive processing. Multiple heating rods 31, a first connecting line 32 and a second connecting line 33 are arranged on the surface of the tank 1 with a heat insulation pad 6.

The bolt 113 is made of high-temperature resistant stainless steel bolt, with matching nuts and washers.

[0042] The working principle of the hot melt adhesive processing heat circulation device provided by this utility model is as follows: When heating rod 31 malfunctions and needs to be replaced, first turn off the power to controller 5 to ensure that the circuit is disconnected and to avoid the risk of electric shock. Use a wrench to loosen and remove the bolts 113 on the rectangular block 112, and then remove the rectangular block 112 from both sides of the removal pad 111.
