Description

Technical Field

[0001] The present application relates to the field of double-sided adhesive tape drying technology, and in particular to a double-sided adhesive tape drying device. Background Art

[0002] After the double-sided tape is produced, the easy-flowing glue on the surface of the tape needs to be dried and solidified to ensure the stickiness and stability of the tape.

[0003] The current drying device mainly heats the air electrically and then transports the heated air to the drying box. The adhesive tape comes into contact with the hot air during the transmission process in the drying box to dry the adhesive liquid. The drying box is connected to an exhaust pipe for the internal gas to be discharged. Since the heat in the hot air will not be completely absorbed and the drying box will also be affected by heat transfer, the whole is in a state of insulation, so that the gas in the box is maintained in a certain temperature range. Therefore, the exhausted air still carries some heat, resulting in a waste of heat resources. Utility Model Content

[0004] In order to improve the problem that the air exhausted from the drying box still carries a portion of heat, resulting in a waste of heat resources, the present application provides a drying device for double-sided tape.

[0005] The present application provides a double-sided tape drying device that adopts the following technical solution:

[0006] A drying device for double-sided adhesive tape, comprising an oven, a heating box, a combustion chamber and a fan;

[0007] The oven is hollow and is used for the tape to pass through;

[0008] The combustion chamber is arranged in the heating box, and a plurality of first heat conducting plates are arranged on the combustion chamber, each of which extends into the combustion chamber, and a gas burner for heating each of the first heat conducting plates is installed on the heating box, and an air inlet pipe and an air outlet pipe communicating with the interior are arranged on the combustion chamber;

[0009] The air inlet of the fan is connected to the heating box through a first pipe, the air outlet of the fan is connected to the oven through a second pipe, and the oven is connected to the heating box through a return pipe.

[0010] By adopting the above technical scheme, the gas burner burns and heats the first heat conducting plate, and the first heat conducting plate heats the air in the heating box after being heated. The heated air is transported to the oven under the traction of the fan to dry the tape; the hot air in the oven is transported from the return pipe to the heating box for reheating. Since the returning hot air still has a certain amount of heat, the time required for heating it is shortened and the required amount of heat is also reduced accordingly, which saves the waste of heat resources and helps to improve the air heating efficiency; in addition, the combustion of the gas burner is separated by the combustion chamber, which prevents the gas in the heating box from direct contact with the open flame, reducing the possibility of some gases that may volatilize during the drying process of the tape encountering the open flame and exploding.

[0011] Optionally, the combustion chamber includes a top surface and a first side surface and a second side surface surrounding the top surface, the first heat conducting plate corresponds to the top surface and is vertically arranged, and the first side surface and the second side surface are both provided with a plurality of second heat conducting plates whose one end extends into the combustion chamber.

[0012] By adopting the above technical solution, the second heat conducting plate cooperates with the first heat conducting plate to increase the area in contact with the air, so that the air is heated faster.

[0013] Optionally, the second heat conducting plate is distributed horizontally, and a plurality of combustion holes are opened at one end of the second heat conducting plate located in the combustion chamber.

[0014] By adopting the above technical solution, the horizontal setting is conducive to reducing the obstruction to the air flow in the heating box; the combustion hole allows the flame to pass through to prevent the flame from being blocked by the second heat conduction plate below.

[0015] Optionally, the first heat conducting plate and the second heat conducting plate are both S-shaped at one end outside the combustion chamber.

[0016] By adopting the above technical solution, the S-shape increases the contact area between the first and second heat conducting plates and the air, further improving the heat transfer efficiency.

[0017] Optionally, the first pipeline and the return pipe are respectively connected to both ends of the heating box along the length direction, the first heat conducting plate is perpendicular to the axis of the output end of the return pipe, and a plurality of through holes are formed on the first heat conducting plate.

[0018] By adopting the above technical solution, the gas flows from the return pipe to the first pipe after being output. The position distribution of the return pipe and the first pipe allows the air to have a longer movement path to fully contact the first heat conduction plate. The through holes allow part of the gas to pass through, thereby ensuring the flow rate that the first pipe can pull.

[0019] Optionally, the first heat conducting plate and the second heat conducting plate are both made of stainless steel.

[0020] By adopting the above technical solutions, stainless steel has corrosion resistance and a long service life.

[0021] Optionally, the return pipe is provided with an insulation pipe on its outer sleeve, both ends of the insulation pipe are sealed with the return pipe, the air outlet pipe is connected to the insulation pipe, and the insulation pipe is connected to an exhaust pipe connected to the interior.

[0022] By adopting the above technical solution, the heated air in the combustion chamber is transported from the exhaust pipe to the insulation pipe, which has the effect of insulating and heating the gas in the return pipe, which is beneficial to increasing the temperature value of the gas in the return pipe, increasing the reheating speed of the return gas, and improving the utilization rate of heat resources.

[0023] Optionally, a fan is installed in the return pipe.

[0024] By adopting the above technical solution, the fan accelerates the flow of gas in the return pipe into the heating box.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The first heat conducting plate and the second heat conducting plate are heated by the combustion chamber, and then the heated air is sent into the oven by the fan to dry the double-sided tape, thereby improving the drying efficiency; the hot air exhausted from the oven is returned to the heating box for reuse, thus saving heat energy waste; the combustion of the gas burner is blocked, which is beneficial to improving the purity of the heated air in the heating box;

[0027] 2. The number of the first heat conducting plate and the second heat conducting plate and the S-shaped design make the heat distribution more uniform and improve the heat transfer efficiency to the air;

[0028] 3. The insulation pipe and exhaust pipe reuse the hot air in the combustion chamber, which improves the utilization rate of thermal energy and reduces heat loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1 and Figure 2 The embodiment of the present application discloses a drying device for double-sided adhesive tape, including an oven 1, a heating box 2, a combustion chamber 3 and a fan 4. The oven 1 is hollow and is used for transmitting the adhesive tape.

[0037] like Figure 3 The combustion chamber 3 is arranged in the heating box 2, and the combustion chamber 3 includes a top surface and a first side surface and a second side surface surrounding the top surface. A plurality of first heat conducting plates 31 arranged at intervals along the length direction of the combustion chamber 3 are vertically arranged on the top surface. A plurality of through holes 311 are opened at the upper end of each first heat conducting plate 31, and a lower end of each first heat conducting plate 31 extends into the combustion chamber 3.

[0038] like Figure 3 and Figure 4 The first side surface and the second side surface are located on opposite sides of the combustion chamber 3 and are parallel to each other. The first side surface and the second side surface are both provided with a plurality of second heat conducting plates 35 with one end extending into the combustion chamber 3. The second heat conducting plates 35 on each side surface are horizontally distributed and arranged at intervals along the height direction of the combustion chamber 3. A plurality of combustion holes 351 are opened at one end of the second heat conducting plate 35 located in the combustion chamber 3. The width of the end of the second heat conducting plate 35 located in the combustion chamber 3 is smaller than the width of the end of the first heat conducting plate 31 located in the combustion chamber 3, and the second heat conducting plates 35 corresponding to the first heat conducting plates 31 are interlaced with each other.

[0039] The first heat conducting plate 31 and the second heat conducting plate 35 are both S-shaped at one end outside the combustion chamber 3 to increase the contact area with the air. The first heat conducting plate 31 and the second heat conducting plate 35 are preferably made of stainless steel.

[0040] like Figure 3 The side wall of the heating box 2 is equipped with a gas burner 32 for heating each first heat conducting plate 31 and the second heat conducting plate 35. The gas burner 32 is a device that sprays fuel and air in a certain way for mixed combustion. The burner of the gas burner 32 passes through the heating box 2 and the side wall of the combustion chamber 3 and extends into the combustion chamber 3. The combustion chamber 3 is provided with an air inlet pipe 33 and an air outlet pipe 34 connected to the interior thereof, and both the air inlet pipe 33 and the air outlet pipe 34 pass through the outside of the heating box 2. The air inlet pipe 33 is used to transport air into the combustion chamber 3 to ensure that the gas burner 32 has sufficient oxygen, and the air outlet pipe 34 is used to discharge the heated air in the combustion chamber 3 to maintain a stable pressure. Valves are installed on both the air inlet pipe 33 and the air outlet pipe 34.

[0041] like Figure 2 The air inlet of the fan 4 is connected to the heating box 2 through the first pipe 41, the air outlet of the fan 4 is connected to the oven 1 through the second pipe 42, and the oven 1 is connected to the heating box 2 through the return pipe 43.

[0042] like Figure 2 The air inlet of the fan 4 is connected to one end of the heating box 2 along the length direction through the first pipe 41, and the air outlet of the fan 4 is connected to the oven 1 through the second pipe 42. The oven 1 is connected to the other end of the heating box 2 along the length direction through the return pipe 43. The first heat conducting plate 31 is perpendicular to the axis of the output end of the return pipe 43, so that the through hole 311 is directly opposite to the output end of the return pipe 43. A fan 431 is installed in the return pipe 43.

[0043] like Figure 3 The return pipe 43 is provided with an insulation pipe 5, both ends of the insulation pipe 5 are sealed with the return pipe 43, the outlet pipe 34 is connected with the insulation pipe 5, and the insulation pipe 5 is connected with an exhaust pipe 51 connected with the inside. The exhaust pipe 51 can be connected with a dust collector to filter the particles that may exist in the air after combustion, or the exhaust pipe 51 can be connected to a water tank, and the water in the water tank is used to filter and cool the air after combustion before discharge.

[0044] Principle of the embodiment of the present application: During operation, the adhesive tape is transmitted through the oven 1, and the gas burner 32 burns and heats the first heat conducting plate 31 and the second heat conducting plate 35. The first heat conducting plate 31 and the second heat conducting plate 35 transfer heat to the air in the heating box 2, so that the air is heated.

[0045] The fan 4 is started to transport the hot air in the heating box 2 to the oven 1 through the first pipe 41 and the second pipe 42, and the hot air is used to dry the tape; the hot air in the oven 1 is sucked into the heating box 2 through the return pipe 43 under the airflow circulation formed by the fan 4 and the re-traction action of the fan 431, and the refluxed gas passes through each first heat conduction plate 31 and the second heat conduction plate 35 and is heated again.

[0046] The gas in the combustion chamber 3 carries a large amount of heat energy due to combustion. The hot air is transmitted to the insulation pipe 5 through the outlet pipe 34. The heat in the gas is transferred to the gas in the return pipe 43, reducing the loss of heat of the gas in the return pipe 43. Since the gas returning to the heating box 2 has a certain temperature, it does not need to be heated from room temperature, reducing heat energy loss.

[0047] Multiple groups of drying devices can be provided according to the length of the oven 1 to ensure the drying effect of the adhesive tape.

[0048] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
