Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a drying device for producing Teflon tape. Background Art

[0002] Teflon tape, also known as Teflon adhesive tape or Teflon adhesive tape, is a high-temperature resistant tape made by first using glass fiber as the base cloth, coating it with Teflon emulsion and drying it to make Teflon glass fiber cloth, and then coating it with silicone adhesive for the second time. In the processing of Teflon tape, drying the Teflon emulsion is a very important link. Drying equipment is required for drying the Teflon emulsion, but traditional drying equipment can only dry one side of the tape, which reduces the drying efficiency, and the Teflon tape is prone to shaking during the winding process of the winding machine.

[0003] After searching, a drying device for Teflon tape processing disclosed in the prior art (application number: CN202121597082.4) records that "a drying bin is fixedly installed on the top surface of the workbench, a winding machine is fixedly installed on the top surface of the workbench, two bases are fixedly installed on the workbench, and the two bases are respectively located on the left and right sides of the drying bin. A mobile bin is fixedly installed on the top surface of the base. The inner wall of the drying bin is movably connected with three movable rollers through a sealed bearing. A drying mechanism is provided inside the drying bin to dry the tape. A clamping mechanism is provided on the top of the base to fix the tape during the winding process of the winding machine. A moving mechanism is provided inside the mobile bin to drive the clamping mechanism to move and clamp and fix the tape." After the device is started by the hot air blower, the hot air will pass through the annular wind bin and the outlet. The air duct blows to the outer surface of the Teflon tape, so that each side of the tape will contact with the hot air, thereby achieving the effect of drying the tape on multiple sides at the same time; and after the motor is started, the output shaft of the motor drives the threaded rod to rotate forward, and when the threaded rod rotates, the two rotating rollers move in opposite directions to clamp and fix the tape, thereby achieving the effect of clamping and fixing the tape. However, the device heats the surface of the material through hot air to evaporate water molecules to achieve the purpose of drying, but it consumes more electrical energy to maintain the temperature of the transported hot air, and the distance between the air outlet duct and the Teflon tape is large. Therefore, as the hot air is blown, more energy is lost in the process of contact with the material, and the two end ports of the device are connected to the outside world, which will increase the heat loss rate, and the device also lacks the recycling of the blown hot air, which makes the overall energy consumption of the device large.

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] Reference Figures 1 to 4As shown, the utility model provides a drying device for Teflon tape production, including: a box body 1 and a recovery box 8, wherein a feed port and a discharge port are respectively provided at both ends of the box body 1, and positions near the feed port and the discharge port in the box body 1 are movably connected to guide rollers 2 through bearings, and at the same time, the upper surface of the box body 1 is fixedly connected to a hot air blower 11, and a drying box 6 is fixedly connected to the box body 1 through a mounting plate 15, and a diverter slot 7 is provided in the drying box 6, and the diverter slot 7 is connected to the hot air blower 11 through an air pipe, and a baffle plate 4 is fixedly connected to one end of the bottom of the box body 1 near the feed port, and the box body 1 is movably connected to a filter plate 5 through a positioning frame 3, the filter plate 5 is located just above the baffle plate 4, and at the same time, a recovery box 8 is fixedly connected to the top of the box body 1, the lower surface of the recovery box 8 is symmetrically connected to a recovery pipe 12, the upper surface of the recovery pipe 12 is fixedly connected to a protective plate 14 through a support rod 13, and the recovery box 8 is connected to a preheating box 9 through a ventilation pipe, and one end of the preheating box 9 away from the ventilation pipe is connected to an exhaust fan 16, and at the same time, the preheating box 9 and the exhaust fan 16 are both fixedly connected to the upper surface of the box body 1, and a heat conducting plate 10 is symmetrically connected to one side of the preheating box 9 close to the hot air blower 11.

[0020] In the present embodiment, the Teflon tape moves in the box body 1 through the winding mechanism, and under the guidance of the guide roller 2 in the box body 1, the Teflon tape can pass through the gap between the filter plate 5 and the baffle plate 4, and move obliquely in the inner cavity of the drying box 6, and the switch of the hot air blower 11 is started. The hot air blower 11 inputs the hot air into the diverter slot 7 provided in the drying box 6 through the air supply pipe, and the hot air is directly blown to different surfaces of the Teflon tape through the air outlet holes provided in the diverter slot 7, and the air flow of the hot air blown out flows obliquely downward along the surface of the Teflon tape, so the drying box 6 can not only dry the internal Teflon tape, but also preheat the Teflon tape that has not entered the drying box 6 accordingly, wherein the filter plate 5 is made of activated carbon material, which can absorb the moisture carried in the hot air accordingly, thereby assisting in reducing the humidity in the box body 1, and the arrangement of the filter plate 5 and the baffle plate 4 can The hot air flowing out of the drying box 6 is blocked accordingly, which can not only reduce the probability of the hot air being blown out directly from the feed port, but also help increase the temperature of the part of the Teflon tape that has not entered the drying box 6, thereby improving the preheating effect of the Teflon tape. After that, the switch of the exhaust fan 16 is started, and the exhaust fan 16 extracts the gas in the box body 1 through the recovery box 8, and the amount of gas extracted by the recovery box 8 is greater than the amount of gas blown out of the drying box 6. Therefore, the external air flow will flow in through the feed port and the discharge port of the box body 1, thereby helping to reduce the probability of heat outflow. When the hot air flows into the preheating box 9, the heat conduction plate 10 will transfer the heat of the hot air to the vicinity of the air inlet of the hot air blower 11, and then the air extracted by the hot air blower 11 can be preheated accordingly, helping to reduce the energy consumption of the hot air blower 11 when heating the air, and the exhaust fan 16 can transport the hot air to other places through the corresponding pipeline, thereby improving the utilization efficiency of the hot air.

The drying box 6 and the mounting plate 15 are respectively fixedly connected to both sides inside the box body 1. At the same time, one end of the drying box 6 close to the discharge port is inclined obliquely upward.

[0022] In this embodiment, as Figure 1 and Figure 2 , the inclined setting of the drying box 6 can correspondingly restrict the flow direction of the hot air, ensure that the hot air carrying moisture can flow obliquely downward, and ensure the drying effect of the dried part of the Teflon tape.

[0023] As a preferred embodiment, the diversion groove 7 opened in the drying box 6 has a concave structure, and a plurality of groups of air outlet holes are opened on the inner side surface of the drying box 6 at equal intervals in parallel. One end of the air outlet hole far from the diversion groove 7 is inclined obliquely downward. At the same time, the drying box 6 and the mounting plate 15 are combined together to form a square tube structure.

[0024] In this embodiment, as Figure 1 and Figure 2 , the structural settings of the diversion groove 7 and the air outlet holes enable the Teflon tape to be comprehensively blown by hot air in the drying box 6. At the same time, the Teflon tape is dried in a relatively small space, which can not only reduce the loss of heat but also improve the accumulation of heat, thereby enhancing the drying effect of the Teflon tape.

[0025] As a preferred embodiment, there are two groups of positioning frames 3. Both groups of positioning frames 3 have a U-shaped structure, and the filter plate 5 movably connected in the groove of the positioning frame 3 has a rectangular structure. At the same time, the lower surface of the filter plate 5 has a semi-circular arc surface structure.

[0026] In this embodiment, as Figure 1 and Figure 3 , the setting of the positioning frame 3 enables the filter plate 5 to be conveniently loaded and unloaded in the box body 1, thus avoiding improving the replacement efficiency of workers. Through the arc surface structure of the lower surface of the filter plate 5, the probability of the filter plate 5 interfering with the Teflon tape can be reduced. At the same time, the filter plate 5 is made of activated carbon material, which can correspondingly absorb the moisture carried in the hot air and can also assist in reducing the probability of the hot air flowing directly out of the feed port.

[0027] As a preferred embodiment, the flow blocking plate 4 has a rectangular structure. The length of the flow blocking plate 4 is less than the width inside the box body 1, and a heat storage cavity is opened in the flow blocking plate 4. The cross-section formed by the combination of the flow blocking plate 4 and the heat storage cavity is a square structure. At the same time, the upper surface of the flow blocking plate 4 has a semi-circular arc surface structure.

[0028] In this embodiment, as Figure 1 and Figure 3The hollow structure of the spoiler 4 allows the temperature of the surface of the spoiler 4 to increase rapidly, thereby helping to improve the preheating effect of the Teflon tape. At the same time, the curved surface structure of the upper surface of the spoiler 4 can reduce the probability of the spoiler 4 interfering with the Teflon tape.

[0029] As a preferred embodiment, the recovery box 8 has a rectangular structure, and a plurality of recovery tubes 12 are fixedly connected to the lower surface of the recovery box 8 in parallel and at equal intervals, and the recovery tubes 12 have a cylindrical structure, and the support rods 13 symmetrically connected to the upper surface of the recovery tubes 12 have a cylindrical structure, and the protective plate 14 fixedly connected to the support rods 13 has a circular structure, and the lower surface of the protective plate 14 has a spherical protrusion.

At the same time, the structural setting of the protective plate 14 can not only reduce the impact force of the airflow, but also prevent the condensed water in the recovery box 8 from falling into the box body 1 through the recovery pipe 12.

[0031] As a preferred embodiment, the preheating box 9 has a square structure, and a plurality of sets of heat conducting plates 10 are fixedly connected in parallel and at equal intervals near the air inlet of the hot air blower 11, and the guide plate has a rectangular structure.
