[0019] 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 described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1-13 The embodiment of the present invention provides a high-precision hot melt adhesive and oil adhesive multifunctional compound machine, comprising a housing 1 and a coating roller 4, wherein the coating roller 4 is rotatably connected in the housing 1, a material bin 2 is provided at the upper part of the housing 1, and a dipping bin 3 is provided at the lower part of the housing 1, and further comprising: A partition plate 102, the interior of the housing 1 is divided into a first cavity 1021 and a second cavity 1022 by the partition plate 102; A multifunctional component, comprising a heating wire 103, a conduit 7, an adaptive component 8, a heat flow pipe 9 and a fan 11, wherein the heating wire 103 is arranged in the second cavity 1022, one end of the conduit 7 is connected to the second cavity 1022, the heat flow pipe 9 is connected to the conduit 7 through the adaptive component 8, and the fan 11 is arranged at the lower part of the housing 1; When applying oil glue, the fan 11 sucks the second cavity 1022, and the second cavity 1022 is in a negative pressure state, so that the heat flow tube 9 collects the harmful gas emitted from the top of the silo 2. When applying hot melt adhesive, the fan 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 passively drives the heat flow tube 9 to move downward, so that the heat flow heats the raw materials in the silo 2 with the hot melt adhesive.

[0021] In the embodiment of the present invention, when applying the oil glue, the oil glue is added to the material bin 2 and the dipping bin 3, the oil glue and the coating roller 4 are handed over, the oil glue is released by the coating roller 4 for dipping, and the oil glue can be applied to the material belt by the rotation of the coating roller 4; The inner cavity of the shell 1 can be divided by the partition plate 102 to separate the first cavity 1021 and the second cavity 1022. The fan 11 is used to extract air, and 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 under negative pressure, the conduit 7 is also under negative pressure. The heat flow pipe 9 is connected to the conduit 7 through the adaptive component 8. Therefore, the harmful gas emitted by the oil 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 discharged outward through the suction of the fan 11. The fan 11; When applying hot melt adhesive, it is necessary to add hot melt adhesive particles into the silo 2 and heat it. The heating wire 103 is arranged in the second cavity 1022. The position of the heating wire 103 corresponds to the silo 2. When the heating wire 103 is energized, the heating wire 103 heats the silo 2 and heats the air in the second cavity 1022 simultaneously. When the fan 11 is turned on, the fan 11 extracts external air and injects it into the second cavity 1022. When the air enters the second cavity 1022, it is heated by the heating wire 103. After heating, the hot air flows through the silo 2. The conveying of the conduit 7 enters the heat flow tube 9 and is discharged from the heat flow tube 9. After the pressure in the conduit 7 increases, the adaptive component 8 will passively move downward. After the adaptive component 8 moves downward, it will synchronously drive the heat flow tube 9 to move downward. The heat flow tube 9 will be immersed in the silo 2. Through the discharge of the heat flow, the raw materials in the silo 2 can be heated to improve the heating efficiency of the silo 2; and because the heat flow flowing out of the heat flow tube 9 can blow the hot melt adhesive particles to move, the fluidity of the hot melt adhesive particles in the silo 2 is increased, which further improves the heating efficiency of the hot melt adhesive.

[0022] In the embodiments of the present invention, please refer to Figure 4 and Figure 5The adaptive component 8 includes a three-way pipe 81, a telescopic rod 82, a bracket 83, a delivery pipe 85, and a connecting sleeve 86. The three-way pipe 81 is fixedly mounted on the guide tube 7, the upper end of the telescopic rod 82 is slidably inserted in the three-way pipe 81, and the lower end of the telescopic rod 82 is slidably inserted in the housing 1. The bracket 83 is fixedly mounted on the telescopic rod 82, the delivery pipe 85 is fixedly mounted on the three-way pipe 81, the connecting sleeve 86 is fixedly mounted on the lower part of the bracket 83, the upper end of the connecting sleeve 86 is slidably inserted in the delivery pipe 85, and the heat flow pipe 9 is rotatably connected to the lower part of the connecting sleeve 86. It also includes an elastic member 84, which is movably sleeved on the telescopic rod 82, and the elastic member 84 applies a vertical upward thrust to the bracket 83.

[0023] When applying the oil glue, the fan 11 sucks the second cavity 1022, and the second cavity 1022 is in a negative pressure state. At this time, the three-way pipe 81 is also in a negative pressure state. At this time, the three-way pipe 81 provides an upward attraction to the telescopic rod 82, and cooperates with the elastic force of the elastic member 84 to make the telescopic rod 82 move 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 silo 2 to suck the harmful gas emitted by the oil glue in the silo 2; when applying the hot melt adhesive, the hot melt adhesive particles are added. Placed in the silo 2, first need to turn on the heating wire 103 to energize, after the heating wire 103 is energized, the heating wire 103 will heat the silo 2, and synchronously heat the air in the second cavity 1022, turn on the fan 11 to reverse, inject the 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 three-way pipe 81 increases, the telescopic rod 82 will be subjected to a downward pressure, under the action of pressure, the telescopic rod 82 will overcome the elastic member 84 to move, the telescopic rod 82 moves downward, so that the connecting sleeve 86 is synchronously moved down to the attached Figure 4 In the state shown, at this time, the heat flow pipe 9 is inside the silo 2, and the hot melt adhesive particles are continuously added through the heat flow pipe 9. Combined with the overall temperature increase of the silo 2, the melting rate of the hot melt adhesive particles is significantly improved. 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 silo 2 is increased, thereby further improving the heating efficiency of the hot melt adhesive.

[0024] In another embodiment of the present invention, please refer to Figure 6 , Figure 7 , Figure 8 , Fig. 9, further comprising a flow dividing portion, which comprises a flow dividing plate 104 and a connecting component 12, wherein the flow dividing plate 104 is hinged in the second cavity 1022, and the connecting component 12 has a first state and a second state. When applying oil glue, the connecting component 12 is in the first state, and the gas sucked from the heat flow pipe 9 enters the connecting component 12 through the bottom of the flow dividing plate 104. When applying hot melt adhesive, the connecting component 12 is in the second state, and the gas flowing out of the connecting component 12 passes through the top of the flow dividing plate 104, so that the gas is fully heated and then flows into the heat flow pipe 9.

[0025] The second cavity 1022 can be divided into two air circulation channels by hingedly connecting the splitter plate 104 in the second cavity 1022, so that the air passes through different air circulation channels when the oil adhesive is applied and the hot melt adhesive is applied respectively; When the oil glue is applied, the fan 11 is in the process of extracting the gas in the second cavity 1022, and the harmful gas emitted by the oil glue is sucked. Fig. 9 As shown, the sucked gas will flow through the lower part of the diverter plate 104, and the harmful gas will flow from the lower part of the diverter plate 104 to the connecting component 12 and then flow into 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; When applying hot melt adhesive, please refer to Figure 8 , the fan 11 injects air into the first cavity 1021. At this time, the air pressure increases. The connecting component 12 moves upward under the action of the air pressure and flips so that the air outlet of the connecting component 12 is facing the end direction of the electric heating wire 103. In this way, the lower part of the diverter plate 104 contacts the connecting component 12. At this time, the air flows into the second cavity 1022 through the connecting component 12. Due to the obstruction of the diverter plate 104, the external air will circulate from the top of the diverter plate 104, and ensure that the external air can fully contact the electric heating wire 103 to ensure that the heated air can reach a sufficient temperature, so that the heat flow formed can better heat the hot melt adhesive particles in the silo 2.

[0026] In the embodiments of the present invention, please refer to Figure 4-7 The connecting 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, and the inner sleeve 122 is slidably connected to the inner wall of the outer sleeve 121. An air outlet 1221 is opened on 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.

[0027] When applying the oil glue, the fan 11 sucks the air in the first cavity 1021, so that the air in the second cavity 1022 will flow into the first cavity 1021 through the connecting component 12. At this time, the feeding prevents the gas sucked by the heat flow tube 9 from contaminating the heating wire 103. By setting a diverter plate 104 in the second cavity 1022, the gas sucked by the heat flow tube 9 can be diverted, so that the gas sucked by the heat flow tube 9 flows from the lower part of the diverter plate 104, avoiding the contact between the gas sucked by the heat flow tube 9 and the heating wire 103, avoiding contamination of the heating wire 103. At this time, the opening of the air outlet 1221 is as shown in the attached figure. Fig. 9 As shown in , the gas at the lower part of the diverter plate 104 can flow directly into the inner sleeve 122, thus greatly reducing the probability of the heating wire 103 being contaminated; When hot melt adhesive is applied, the fan 11 draws external gas 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 pressure in the first cavity 1021 increases, which will produce 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 also passively rotates 180 degrees. When the inner sleeve 122 rotates 180 degrees, its tuyere 1221 rotates synchronously. At this time, the tuyere 1221 will rotate to the attached Fig.10 As shown, the airflow flowing out through the air outlet 1221 will flow along the upper part of the diverter plate 104. During the flow of the gas along the upper part, it can fully contact the heating wire 103, so that the airflow can be fully heated.

[0028] See also Fig.10 The lower part of the housing 1 is provided with a heat preservation chamber 101, and one end of the electric heating wire 103 extends into the heat preservation chamber 101. The heat preservation chamber 101 has little heat loss, and the heat preservation chamber 101 can be used to keep the raw materials in the dipping bin 3 warm to prevent the hot melt adhesive from solidifying.

[0029] It includes a power roller 6, which is rotatably connected to the housing 1. The base fabric layer needs to be wound on the power roller 6, and the power roller 6 needs to be parallel to the coating roller 4 to ensure uniform coating.

[0030] It also includes a protective cover 5, which is fixedly installed in the housing 1. The protective cover 5 and the coating roller 4 are concentric, and the gap between the lower part of the protective cover 5 and the silo 2 is smaller than the diameter of the hot melt adhesive particles.

[0031] The protective cover 5 plays a role of heat preservation, ensuring the sol coating and reducing the heat loss of the hot melt adhesive on the coating roller 4; in the coating process of the oil glue, since the oil glue is dipped by the coating roller 4 and has a large contact area with the air, the dissipation is very serious. Therefore, due to the suction of the heat flow pipe 9, the oil glue on the coating roller 4 is easy to be lost in large quantities. The protective cover 5 can isolate the heat flow pipe 9 from sucking the coating roller 4, thereby reducing the loss of the oil glue on the coating roller 4.

[0032] A flow hole 91 is opened in the radial direction of the heat flow tube 9, and an air guide plate 92 is arranged on the circumferential surface of the heat flow tube 9. The arrangement of the flow hole 91 and the air guide plate 92 ensures that the airflow is not perpendicular to the heat flow tube 9 when leaving the heat flow tube 9. The heat flow tube 9 will also be subjected to a reaction force, so that the heat flow tube 9 will rotate during the heat flow discharge process, so as to better disperse the hot melt adhesive particles and increase its fluidity.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various 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.
