[0001] The present invention relates to the technical field of multi-functional compound machines, and particularly to a high-precision hot melt adhesive and oil adhesive multi-functional compound machine. Background Art

[0002] The multi-functional compound machine can bond laminated products. According to different products, its adhesives are divided into hot melt adhesives and oil adhesives. Among them, the hot melt adhesive is solid at room temperature and needs to be heated at high temperature during use, melted and coated onto the base layer through a coating roller. The oil adhesive is a liquid glue made of acrylic acid or polyurethane resin as the glue raw material and added with oily solvents (such as toluene, DMF, ketone, etc.). It can be coated using a coating roller without heating, but the oil adhesive will emit toxic gases and corresponding protection needs to be done.

[0003] The current multi-functional compound machine can perform the coating of hot melt adhesive or oil adhesive respectively according to actual needs. Therefore, the multi-functional compound machine needs to set a heating structure in the coating chamber to heat and melt the hot melt adhesive raw material, and set an exhaust structure above the coating chamber to suck the gases emitted by the oil adhesive when performing oil adhesive coating. The current heating structure generally uses the overall heating method of the coating chamber. Since the raw materials are mostly in the form of hot melt adhesive particles and have poor fluidity, the equipment needs a long time to heat up. Summary of the Invention

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the drawings.

[0035] Please refer to Figures 1-13 , a high - precision hot - melt adhesive and oil - based adhesive multi - functional compounding machine provided by an embodiment of the present invention includes a shell 1 and a coating roller 4. The coating roller 4 is rotatably connected inside the shell 1. A hopper 2 is arranged at the upper part of the shell 1, and a dipping bin 3 is arranged at the lower part of the shell 1. It further includes:

[0036] A partition board 102, and the interior of the shell 1 is divided into a first cavity 1021 and a second cavity 1022 by the partition board 102;

[0037] A multi - functional component, which includes an electric heating wire 103, a pipe 7, an adaptive component 8, a heat - flow tube 9, and a fan 11. The electric heating wire 103 is arranged in the second cavity 1022. One end of the pipe 7 is connected to the second cavity 1022. The heat - flow tube 9 is connected to the pipe 7 through the adaptive component 8. The fan 11 is arranged at the lower part of the shell 1;

[0038] When applying oil-based glue, the blower 11 sucks the inside of the second cavity 1022, and the second cavity 1022 is in a negative pressure state, so as to collect the harmful gases escaping above the material bin 2 by the heat flow pipe 9. When applying hot melt adhesive, the blower 11 injects air into the second cavity 1022, and the second cavity 1022 is in a high pressure state. At this time, the adaptive component 8 drives the heat flow pipe 9 to move downward passively, so that the heat flow heats the raw materials in the material bin 2 with hot melt adhesive.

[0039] In the embodiment of the present invention, when applying oil-based glue, the oil-based glue is added to the material bin 2 and the dipping bin 3, and the oil-based glue and the coating roller 4 are handed over. The oil-based glue is released by the coating roller 4 for dipping, and the oil-based glue can be coated on the material tape by the rotation of the coating roller 4;

[0040] The inner cavity of the housing 1 can be separated by the partition plate 102 to separate the first cavity 1021 and the second cavity 1022. By exhausting air through the blower 11, a negative pressure can be generated in the second cavity 1022. One end of the conduit 7 is connected to the second cavity 1022. Therefore, when the second cavity 1022 is in a negative pressure, the conduit 7 is also in a negative pressure. The heat flow pipe 9 is connected to the conduit 7 through the adaptive component 8. Therefore, the harmful gases escaping from the oil-based glue will be sucked into the conduit 7 through the heat flow pipe 9, and then enter the second cavity 1022 through the suction of the conduit 7, and finally be discharged outward through the suction of the blower 11, blower 11;

[0041] When applying hot melt adhesive, it is necessary to add and heat hot melt adhesive particles in the material bin 2. The heating wire 103 is arranged in the second cavity 1022, and the position of the heating wire 103 corresponds to that of the material bin 2. When the heating wire 103 is energized, the heating wire 103 will heat the material bin 2 and synchronously heat the air in the second cavity 1022. When the blower 11 is turned on, the blower 11 extracts external gas and injects it into the second cavity 1022. When the gas enters the second cavity 1022, it will be heated by the heating wire 103. After heating, the hot air flow enters the heat flow pipe 9 through the delivery of the conduit 7 and is discharged from the heat flow pipe 9. After the pressure in the conduit 7 increases, the adaptive component 8 will move downward passively. After the adaptive component 8 moves downward, it will drive the heat flow pipe 9 to move downward synchronously. The heat flow pipe 9 will be immersed in the material bin 2. Through the discharge of the heat flow, the raw materials in the material bin 2 can be heated to improve the heating efficiency of the material bin 2; and because the heat flow flowing out of the heat flow pipe 9 can blow the hot melt adhesive particles to move, so that the fluidity of the hot melt adhesive particles in the material bin 2 is increased, which further improves the heating efficiency of the hot melt adhesive.

[0042] In the embodiment of the present invention, please refer to Figure 4 and Figure 5, the adaptive component 8 includes a tee 81, a telescopic rod 82, a bracket 83, a delivery pipe 85, and a connecting sleeve 86. The tee 81 is fixedly installed on the conduit 7. The upper end of the telescopic rod 82 is slidably inserted into the tee 81, and the lower end of the telescopic rod 82 is slidably inserted into the housing 1. The bracket 83 is fixedly installed on the telescopic rod 82. The delivery pipe 85 is fixedly installed on the tee 81. The connecting sleeve 86 is fixedly installed on the lower part of the bracket 83. The upper end of the connecting sleeve 86 is slidably inserted into the delivery pipe 85. The heat flow pipe 9 is rotatably connected to the lower part of the connecting sleeve 86. An elastic member 84 is further included. The elastic member 84 is movably sleeved on the telescopic rod 82, and the elastic member 84 exerts an upward thrust on the bracket 83.

[0043] When applying oil-based glue, the blower 11 sucks the second cavity 1022, and the second cavity 1022 is in a negative pressure state. At this time, the tee 81 is also in a negative pressure state. At this time, the tee 81 provides an upward attraction to the telescopic rod 82, and with the elastic force of the elastic member 84, the telescopic rod 82 moves upward. When the telescopic rod 82 moves upward, it can synchronously drive the bracket 83 to move. When the bracket 83 moves, it can synchronously drive the connecting sleeve 86 to move upward. In this way, when the connecting sleeve 86 moves upward, the heat flow pipe 9 moves upward. In this way, the heat flow pipe 9 is above the material bin 2 to suck the harmful gases emitted from the oil-based glue in the material bin 2. When applying hot melt adhesive, the hot melt adhesive particles are added to the material bin 2. First, the heating wire 103 needs to be turned on and powered. After the heating wire 103 is powered on, the heating wire 103 heats the material bin 2 and synchronously heats the air in the second cavity 1022. When the blower 11 is reversed to inject external gas into the second cavity 1022, when the gas enters the second cavity 1022, it will be heated by the heating wire 103. After heating, the hot air flow is transported through the conduit 7 into the heat flow pipe 9 and discharged from the heat flow pipe 9. During this process, the pressure in the tee 81 increases, and the telescopic rod 82 will receive a downward pressure. Under the action of the pressure, the telescopic rod 82 will overcome the elastic member 84 and move. The telescopic rod 82 moves downward, causing the connecting sleeve 86 to move downward synchronously to the state as shown in the appendix Figure 4 shown. At this time, the heat flow pipe 9 is inside the material bin 2, and continuously heats the hot melt adhesive particles through the heat flow pipe 9. With the overall temperature rise of the material bin 2, the melting speed of the hot melt adhesive particles is significantly increased. Moreover, the heat flow pipe 9 is inside the hot melt adhesive particles. Under the action of the heat flow, the fluidity of the hot melt adhesive particles in the material bin 2 increases, which further improves the heating efficiency of the hot melt adhesive.

[0044] In another embodiment of the present invention, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9, further comprising a flow splitting portion, which includes a flow splitting plate 104 and a connection component 12. The flow splitting plate 104 is hinged in the second cavity 1022, and the connection component 12 has a first state and a second state. When applying oil-based adhesive, the connection component 12 is in the first state, and the gas sucked from the heat flow pipe 9 enters the connection component 12 through the lower part of the flow splitting plate 104. When applying hot melt adhesive, the connection component 12 is in the second state, and the gas flowing out of the connection component 12 will pass above the flow splitting plate 104, so that the gas is fully heated and then flows into the heat flow pipe 9.

[0045] By hinging the flow splitting plate 104 in the second cavity 1022, two air circulation channels can be separated in the second cavity 1022. In this way, different air circulation channels are passed through during oil-based adhesive coating and hot melt adhesive coating respectively;

[0046] When applying oil-based adhesive, at this time, the fan 11 is in the function of sucking the gas in the second cavity 1022. When sucking the harmful gas dissipated by the oil-based adhesive, such as Figure 9 As shown, the sucked gas will flow through the lower part of the flow splitting plate 104, and the harmful gas moves from the lower part of the flow splitting plate 104 to the connection component 12 and then to the first cavity 1021, so as to prevent the harmful gas from contacting the heating wire 103 and avoid contamination of the heating wire 103;

[0047] When applying hot melt adhesive, reference can be made to Figure 8 , the fan 11 injects air into the first cavity 1021. At this time, the air pressure increases. Under the action of the air pressure, the connection component 12 moves upward and flips, so that the air outlet of the connection component 12 faces the end direction of the heating wire 103. In this way, and the lower part of the flow splitting plate 104 abuts against the connection component 12. At this time, the air flows into the second cavity 1022 through the connection component 12. Due to the shielding of the flow splitting plate 104, the external air will flow above the flow splitting plate 104, and ensure that the external air can fully contact the heating wire 103 to ensure that the heated air can reach a sufficient temperature, so that the formed heat flow can better heat the hot melt adhesive particles in the material bin 2.

[0048] In the embodiment of the present invention, please refer to Figures 4-7 , the connection component 12 includes an outer sleeve 121 and an inner sleeve 122. The outer sleeve 121 is fixedly installed at the bottom of the partition plate 102, the inner sleeve 122 is slidably connected to the inner wall of the outer sleeve 121, an air outlet 1221 is opened at the upper part of the inner sleeve 122, a ring groove 1211 is opened on the inner wall of the outer sleeve 121, and an embedded ball 1222 is opened on the outer wall of the inner sleeve 122.

[0049] When applying oil-based glue, the blower 11 sucks the air in the first cavity 1021. In this way, the air in the second cavity 1022 will flow into the first cavity 1021 through the connecting component 12. At this time, to prevent the gas sucked by the feeding heat pipe 9 from contaminating the heating wire 103, by arranging a flow dividing plate 104 in the second cavity 1022, the gas sucked by the heat pipe 9 can be divided, so that the gas sucked by the heat pipe 9 flows from the lower part of the flow dividing plate 104, avoiding the contact between the gas sucked by the heat pipe 9 and the heating wire 103 and preventing the contamination of the heating wire 103. At this time, the opening of the air outlet 1221 is as shown in the appendix Figure 9 As shown, the gas at the lower part of the flow dividing plate 104 can directly flow into the inner sleeve 122. In this way, the probability of the heating wire 103 being contaminated is greatly reduced;

[0050] When applying hot melt adhesive, the blower 11 sucks external gas and injects it into the first cavity 1021. At this time, the gas pressure in the first cavity 1021 increases, and the gas will flow into the second cavity 1022 through the connecting component 12. At this time, the increase in the pressure in the first cavity 1021 will generate an upward thrust on the inner sleeve 122, and the inner sleeve 122 will move upward. During the upward displacement of the inner sleeve 122, the embedded ball 1222 will move along the annular groove 1211. Since the embedded ball 1222 is fixed on the inner sleeve 122, during the upward movement of the inner sleeve 122, it will also rotate passively by 180 degrees. When the inner sleeve 122 rotates 180 degrees, its air outlet 1221 will rotate synchronously. At this time, the air outlet 1221 will rotate to the position shown in the appendix Figure 10 As shown, at this time, the air flow flowing out through the air outlet 1221 will flow along the upper part of the flow dividing plate 104. During the process of the gas flowing along the upper part, it can fully contact the heating wire 103 so that the air flow can be fully heated.

[0051] Please refer to Figure 10 , a heat preservation cavity 101 is arranged at the lower part of the housing 1, and one end of the heating wire 103 extends into the heat preservation cavity 101. The heat preservation cavity 101 has less heat loss. By arranging the heat preservation cavity 101, the raw materials in the dipping bin 3 can be heat-preserved to prevent the hot melt adhesive from solidifying.

[0052] It includes a driving roller 6, and the driving roller 6 is rotatably connected to the housing 1. The base fabric layer needs to be wound around the driving roller 6, and the driving roller 6 needs to be parallel to the coating roller 4 to ensure uniform coating.

[0053] It further includes a protective cover 5, and the protective cover 5 is fixedly installed in the housing 1. The protective cover 5 is concentric with the coating roller 4, and the gap between the lower part of the protective cover 5 and the material bin 2 is smaller than the diameter of the hot melt adhesive particles.

[0054] The protective cover 5 plays a heat preservation role, ensuring during the sol coating to reduce the heat loss of the hot melt adhesive on the coating roller 4; during the coating process of the oil-based adhesive, since the oil-based adhesive has a large contact area with the air after being dipped by the coating roller 4, the dissipation is very serious. Therefore, due to the suction of the heat flow pipe 9, a large amount of the oil-based adhesive on the coating roller 4 is likely to be lost. The protective cover 5 can isolate the heat flow pipe 9 from sucking the coating roller 4, thus reducing the loss of the oil-based adhesive on the coating roller 4.

[0055] Circulation holes 91 are provided in the radial direction of the heat flow pipe 9, and air guiding vanes 92 are arranged on the circumferential surface of the heat flow pipe 9. Through the arrangement of the circulation holes 91 and the air guiding vanes 92, when the air flow detaches from the heat flow pipe 9, it is not perpendicular to the heat flow pipe 9, and the heat flow pipe 9 will also receive a reaction force, so that during the heat discharge process, the heat flow pipe 9 will rotate, which better disperses the hot melt adhesive particles to increase their fluidity.

[0056] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
