Description

Technical Field

[0001] The invention belongs to the technical field of silk thread baking and drying, and in particular relates to a vertical drying room for glass fiber sewing threads. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. It has many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Glass fiber sewing thread is a sewing thread made of glass fiber drawn and twisted. It is mainly used for sewing in some special high temperature environments and the production of sewing products that require flame retardancy.

[0003] After the glass fiber sewing thread is processed into thread, high temperature is required to remove the slurry on the surface; the treated glass fiber is golden yellow or dark brown, and the residual slurry is about 0.1%. At the same time, there will be a strength loss of about 20%-40%. However, some drying equipment currently used is difficult to effectively control the heating temperature and heating time when drying the glass fiber sewing thread. As the heating time is prolonged and the temperature rises, the residual slurry will decrease, but the resulting strength will become smaller and smaller. Therefore, a drying device that can take into account both the drying effect and the self-strength of the glass fiber sewing thread is proposed. Summary of the invention

[0004] In view of the above problems, the present invention provides a vertical drying room for glass fiber sewing thread, which is used to solve the problem that the existing drying room is not convenient for controlling factors such as drying room temperature and time, which easily affects the strength of the glass fiber sewing thread.

[0018] As a further improvement of the above solution, a spring for pulling the movable hood downward is arranged between the movable hood and the box body, a pull rope is arranged on the top of the movable hood, and the pull rope is connected to a first driving source for pulling the movable hood upward.

[0019] The technical effect of the above improvement is: by changing the movable position of the movable cover on the second combustion tube, the heat of the combustion gas ejected by the guide column into the heating area can be controlled, which is conducive to quickly controlling the drying temperature to facilitate combustion adjustment.

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0043] like Figure 1-12 As shown, the specific scheme of this embodiment is: a vertical drying room for glass fiber sewing thread, including a box body 10; a plurality of drying chambers 101 are arranged in the box body 10, as shown in the attached Figure 1 As shown, two drying chambers 101 are arranged from bottom to top, and the drying chamber 101 includes a first insulating door 105 arranged at the outermost circle, and a second insulating door 106 is arranged inside the first insulating door 105, and the second insulating door 106 and the first insulating door 105 mainly achieve the effect of heat preservation; a driving component 11 for driving the silk thread to move in the drying chamber 101 is arranged on the top of the box body 10, and the silk thread is introduced upward from the drying chamber 101 at the lowermost side, passes through the drying chamber 101, then bypasses the driving component 11 to change direction, and then passes downward from the drying chamber 101 again, so under the drive of the driving component 11, the silk thread can be continuously dried in the drying chamber 101 in a movable manner;

[0044] The drying chamber 101 includes a first drying tube 12 and a second drying tube 13 arranged opposite to each other. A drying zone 14 is formed between the first drying tube 12 and the second drying tube 13 for facilitating the movement and drying of the silk thread. The structures of the first drying tube 12 and the second drying tube 13 can be referred to in the attached drawings. Fig.10 As shown, the first drying tube 12 and the second drying tube 13 are provided with air jets on the sides facing the drying section 14, so when the silk thread passes through the drying section 14, the hot air jetted from the first drying tube 12 and the second drying tube 13 heats the silk thread, thereby drying the silk thread;

[0045] The first drying tube 12 and the second drying tube 13 are respectively provided with temperature detectors 15 for providing feedback for adjusting the drying temperature. The temperature detector 15 is specifically a set temperature sensor, and specifically, also includes a PLC controller. The PLC controller controls various programs of the entire device. The temperature detector 15 and the PLC controller are connected by signal. When it is detected that the temperature in the first drying tube 12 and the second drying tube 13 is not suitable for the drying temperature, signal feedback is performed to facilitate the device to adjust the drying temperature. In addition, two drying chambers 101 are provided, and the number of drying chambers 101 connected to the drying can be adjusted according to the situation during drying. The more the number, the longer the time for the silk thread drying process. Therefore, the drying time can be controlled, thereby preventing the strength of the silk thread from being reduced under the premise of ensuring the drying quality of the silk thread.

[0046] As a preferred embodiment of the above embodiment, a partition 104 is provided in the drying chamber 101, and the partition 104 divides the drying chamber 101 into a heating area 102 and a drying area 103. Figure 4The first drying tube 12, the second drying tube 13, and the drying zone 14 are arranged in the drying area 103; a heating component 16 for providing heat is provided in the heating area 102, and the heating component 16 mainly provides heat energy for drying after combustion.

[0047] like Figure 4 As shown in the figure, as a preferred mode of the above embodiment, the first drying tube 12 and the second drying tube 13 are respectively provided with fans 29 for introducing the hot air in the heating area 102 into the first drying tube 12 and the second drying tube 13. Specifically, two fans 29 are provided, which are respectively used to supply air to the first drying tube 12 and the second drying tube 13. Figure 4 Only one is shown in the figure; specifically, the second baking tube 13 is connected to the heating area 102 by setting an air duct. In this embodiment, the second baking tube 13 and the heating area 102 are close to each other, so the air duct is an opening, and the fan 29 is arranged at the opening. When started, hot air is introduced into the second baking tube 13. An air guide 17 that runs through the second baking tube 13 is arranged between the first baking tube 12 and the heating area 102. Specifically, the air guide 17 is an air guide duct, which is used to introduce hot air into the first baking tube 12 after the fan 29 is started. The first baking tube 12 and the second baking tube 13 are separated and two separate fans 29 are used for exhaust, which can reduce the interference of air outlet between the first baking tube 12 and the second baking tube 13, and make the air outlet of the first baking tube 12 and the second baking tube 13 uniform; the structure of the first baking tube 12 and the second baking tube 13 can refer to the attached Fig.10 , what is shown is one side of the air outlet, and there are multiple first drying tubes 12 and second drying tubes 13, which are arranged in sequence downward, and only two are shown in the figure.

[0048] like Figure 3 , 5 , 6, and 11, as a preferred embodiment of the above embodiment, the heating component 16 includes a first combustion tube 18 and a second combustion tube 19 arranged in the heating area 102. The first combustion tube 18 and the second combustion tube 19 are arranged to be interconnected, and a burner 20 is provided on one side of the first combustion tube 18. The burner 20 is connected to the gas port and the air port. After ignition, the burner 20, the first combustion tube 18, and the second combustion tube 19 burn to generate heat.

[0049] The second combustion tube 19 is provided with a plurality of first through holes 191 penetrating inside and outside to facilitate heat dissipation after combustion. Fig.11 As shown;

[0050] A movable cover 22 is slidably provided on the top of the second combustion tube 19, and a plurality of second through holes 221 that can overlap with the first through holes 191 are provided on the movable cover 22. A guide groove 222 is also provided on the movable cover 22, and the guide groove 222 and the guide column 192 provided on the outer wall of the second combustion tube 19 are slidably provided with each other; a spring 23 for pulling the movable cover 22 downward is provided between the movable cover 22 and the box body 10, and a pull rope 24 is provided on the top of the movable cover 22, and the pull rope 24 is connected to a first driving source for pulling the movable cover 22 upward. In the present embodiment, the first driving source is a cylinder or an electric push rod. Specifically, in the control process, the temperature detected by the temperature detector 15 is controlled. When the temperature is too high, the cylinder or the electric push rod is pushed forward, and under the pull of the spring 23, the movable cover 22 is downwardly sleeved on the second combustion tube 1 9, under the guidance of the guide column 192 and the guide groove 222, the movable cover 22 moves linearly on the second combustion tube 19, so that the first through hole 191 and the second through hole 221 do not overlap. At this time, the movable cover 22 closes part of the first through hole 191 to gradually isolate the hot air ejected from the second combustion tube 19 to reduce the temperature of the hot air for drying. When the guide column 192 moves to the inclined part of the guide groove 222, the movable cover 22 is prompted to rotate relative to the second combustion tube 19, so that the first through hole 191 and the second through hole 221 can be gradually overlapped with each other, so that the ejected hot air can be gradually increased to increase the temperature of the hot air. Therefore, when the movable cover 22 moves to the second combustion tube 19 and is completely fitted together and the movable cover 22 is separated from the second combustion tube 19, the hot air ejected from the second combustion tube 19 is the largest and has the highest temperature.

[0051] As a preferred embodiment of the above embodiment, a first exhaust pipe 25 and a second exhaust pipe 26 located on both sides of the drying zone 14 are further provided in the drying area 103, and the first exhaust pipe 25 and the second exhaust pipe 26 are respectively connected to an exhaust pipe 27 for exhausting air to the outside; an adjusting component 28 is provided on the exhaust pipe 27 for controlling the exhaust size in the exhaust pipe 27, and the adjusting component 28 includes a lever 281 rotatably set on the exhaust pipe 27, and a blocking door 282 is fixedly set on the lever 281. By rotating the lever 281 at different angles, the blocking door 282 can control the exhaust volume on the exhaust pipe 27.

[0052] like Figure 1 , 2 , 7, 8, 9, and 12, as a preferred embodiment of the above embodiment, the driving assembly 11 includes a plurality of driving rollers 111 rotatably arranged on the box body 10, and a plurality of limiting grooves 112 are arranged on the surface of the driving rollers 111 to facilitate limiting the position of the silk thread, as shown in FIG. Fig. 9One end of the driving roller 111 is connected to the second driving source, and the specific second driving source is a motor arranged on the side supporting frame of the box body 10. The motor is connected to the driving roller 111 after being decelerated by the reducer. Chains are used to connect the different driving rollers 111. Therefore, after the motor is started, the driving component 11 can be driven to rotate synchronously, thereby driving the silk thread to move to complete the drying.

[0053] As a preferred embodiment of the above, in order to improve the strength of the wire, the wire is cooled to reduce the long-term high temperature of the wire, and the connecting pipe 113 is rotated at the other end of the driving roller 111, such as Figure 8 The connecting pipe 113 is provided with a water inlet pipe 115 for injecting water into the driving roller 111, and the connecting pipe 113 is also provided with a drain pipe 114 for draining water outward; the liquid level of the water retained in the driving roller 111 does not exceed the horizontal plane where the central axis thereof is located. This arrangement is mainly for the excessively rapid cooling of the silk thread. When the driving roller 111 is completely filled with water, most of the temperature on the silk thread is absorbed and taken away, and the silk thread cools down quickly. Therefore, rapid heating and cooling will also cause the strength of the silk thread to change. When only a part of the water is kept in the driving roller 111, especially when the liquid level of the water in the driving roller 111 is below the horizontal plane where the central axis thereof is located, please refer to the attached Fig.12 The heat of the silk thread is transferred to the surface of the driving roller 111, and the position in contact with the driving roller 111 is first away from the liquid surface and then close to the liquid surface. Therefore, the driving roller 111 will not be cooled down quickly due to the water, but will be cooled down slowly, which not only ensures the cooling effect, but also avoids the cooling speed being too fast, thereby adapting to the properties of the silk thread itself.

[0054] The specific working principle of the present invention is as follows: the silk thread passes upward from the drying chamber 101 through the drying section 14, passes downward through the drying section 14 again after passing through the driving roller 111, and passes out of the drying chamber 101. By starting the motor connected to the driving roller 111, the silk thread can be driven to move in the drying chamber 101;

[0055] During the drying process, by introducing gas and air into the burner 20, the heat generated after ignition is collected in the heating area 102, and the fan 29 is started to introduce the heat into the first drying tube 12 and the second drying tube 13, so as to spray the heat toward the silk threads in the drying area 14, thereby achieving a drying effect on the silk threads;

[0056] The temperature detectors 15 in the first drying tube 12 and the second drying tube 13 can continuously detect the temperature of the introduced hot air. When the temperature detector 15 detects that the temperature is not the set temperature, the signal is transmitted to a PLC controller. The PLC controller controls the movement of the electric push rod connected to the pull rope 24, thereby changing the position of the movable cover 22 relative to the second combustion tube 19, thereby adjusting the temperature of the incoming air to achieve a suitable drying temperature, maintain the strength of the silk thread after drying, and the dried silk thread is led out from the entry position.

It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements, modifications or changes can be made, and the above technical features can also be combined in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the protection scope of the present invention.
