Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically to an energy-saving tape drying and shaping equipment. Background Technology

[0002] In modern industrial production, adhesive tapes are widely used, and drying and shaping, as an indispensable and crucial step in the tape production process, has profoundly impacted the entire tape manufacturing industry through technological development and innovation. Traditional tape drying and shaping equipment has revealed a series of problems during operation. From an energy consumption perspective, most equipment relies primarily on the continuous heating of electric heating tubes to maintain the high-temperature environment required for drying. These heating tubes often maintain a fixed high-power output for extended periods, resulting in high energy consumption. For example, in large-scale tape production plants, numerous drying devices operate simultaneously, making high electricity costs a significant component of production costs, severely compressing profit margins and contradicting the current global advocacy for energy conservation and emission reduction. Furthermore, traditional equipment does not fully utilize heat, and the waste gas generated during the drying process typically... Directly released into the atmosphere, these exhaust gases still contain a large amount of heat energy, which is not effectively recovered and utilized, resulting in a huge waste of energy. This inefficient heat utilization method not only increases the operating costs of enterprises, but also causes unnecessary thermal pollution to the surrounding environment, affecting the ecological balance. In addition, traditional tape drying and shaping equipment has obvious defects in temperature control. Due to the lack of a precise and intelligent temperature control system, it is impossible to adjust the power of the heating tube in real time according to the actual drying state of the tape. This can easily lead to the following problems during the production process: either the heating power is too high, causing the tape to be overheated, which may change its material properties, such as reduced viscosity and damaged strength, seriously affecting the quality of the tape; or the heating power is insufficient, causing the tape to not be fully dried and shaped, and the product does not meet the corresponding quality standards, thereby increasing the defect rate of the product and causing economic losses to the enterprise.

A spring is connected between the limiting plate and the base, and the upper surface of one end of the limiting plate is in contact with the lower surface of the filter plate. The upper outer surface of the filter plate is in contact with the lower end of the guide pipe.

[0011] The above technical solution enables the filter plate to filter the air entering the guide pipe.

[0012] Preferably, the heating box is equipped with a temperature control mechanism, which regulates the power of the electric heating tube by monitoring the air temperature entering the heating box;

[0015] Preferably, the pressure cylinder and the piston plate are connected by sliding friction, and a spring connects the fixed extrusion plate and the movable extrusion plate.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution: an energy-saving tape drying and shaping equipment.

[0032] Example 1:

[0033] This embodiment discloses: a base 1, a mounting frame 2 fixedly mounted on the upper surface of the base 1, a rotating conveying roller 3 mounted on the lower inner surface of the mounting frame 2, a drive motor 4 fixedly mounted on the lower outer surface of the mounting frame 2, a heating fan 5 fixedly mounted inside the upper end of the mounting frame 2, a heating box 6 fixedly mounted on the upper surface of the mounting frame 2, and electric heating tubes 7 fixedly mounted inside both ends of the heating box 6. The surfaces of the base 1 and the mounting frame 2 are provided with a reflux mechanism, which reduces the energy consumption of the electric heating tubes 7 by drawing back the drying exhaust gas.

[0034] The reflux mechanism includes: a suction fan 8, which is fixedly installed inside the lower end of the base 1. The lower end of the guide pipe 9 is fixedly connected inside the lower end of the base 1, and the upper end of the guide pipe 9 penetrates the inner surface of the heating box 6.

[0035] The output shaft of the drive motor 4 is fixedly connected to the conveyor roller 3, and the two conveyor rollers 3 are symmetrically arranged about the heating fan 5, and the heating fan 5 is located directly above the suction fan 8;

[0036] The lower end of the guide tube 9 is connected to the internal cavity of the base 1 where the suction fan 8 is located, and one end of the guide tube 9 that passes through the heating box 6 is located on the side of the heating tube 7 away from the heating fan 5.

[0037] A filter plate 10 is engaged and installed at the lower end of the base 1, and a sliding limiting plate 11 is installed on the lower surface of the base 1. A spring is connected between the limiting plate 11 and the base 1, and the upper surface of one end of the limiting plate 11 is in contact with the lower surface of the filter plate 10, and the outer surface of the upper end of the filter plate 10 is in contact with the lower end of the guide pipe 9.

[0038] The drive motor 4 at the lower end of the mounting bracket 2 is started. The output shaft of the drive motor 4 drives the conveyor roller 3 to rotate, so that the tape can be smoothly conveyed on the conveyor roller 3 and pass through the heating area below the heating fan 5 in sequence to achieve drying and shaping of the tape. Then, the heating fan 5 starts to work, blowing the air heated by the electric heating tube 7 in the heating box 6 onto the surface of the tape to accelerate the evaporation of moisture on the surface of the tape. During the drying process, the suction fan 8 is started. The start of the suction fan 8 creates a negative pressure in the cavity inside the base 1. At this time, under the action of the pressure difference, the outside air carrying the exhaust gas generated during drying is sucked in and transported upward through the guide pipe 9. Since the guide pipe 9 passes through... One end of the heating box 6 is located on the side of the heating tube 7 away from the heating fan 5. The residual heat in the exhaust gas can be mixed with the heat generated by the heating tube 7, reducing the energy consumption required for heating the heating tube 7 alone. Energy saving is achieved by reheating the exhaust gas. During the exhaust gas extraction process, the filter plate 10 plays the role of filtering impurities. The filter plate 10 is snapped into place at the lower end of the base 1. The limiting plate 11 is tightly attached to the filter plate 10 under the action of the spring, ensuring the stability of the filter plate 10 installation, preventing impurities in the exhaust gas from entering the heating fan 5, avoiding damage or blockage to the equipment, and ensuring the normal operation of the equipment and the stable operation of the return mechanism.

[0039] Example 2:

[0040] This embodiment discloses, based on embodiment 1, that: a temperature control mechanism is provided inside the heating box 6, and the power of the electric heating tube 7 is adjusted by monitoring the air intake temperature in the heating box 6;

[0041] The temperature control mechanism includes: a pressure cylinder 12, which is fixedly installed inside the middle section of the heating box 6, and the upper end of the pressure cylinder 12 penetrates the upper surface of the heating box 6. A piston plate 13 is provided inside the pressure cylinder 12, and one end of a linkage rod 14 is fixedly installed on the upper surface of the piston plate 13. The other end of the linkage rod 14 penetrates the inner top surface of the heating box 6. A fixed pressing plate 15 is fixedly connected to one end of the linkage rod 14 inside the heating box 6. A movable pressing plate 16 is slidably connected to one end of the fixed pressing plate 15. A first trigger switch 17 and a second trigger switch 18 are fixedly installed on the inner surfaces of both ends of the heating box 6.

[0042] The pressure cylinder 12 and the piston plate 13 are connected by sliding friction, and a spring is connected between the fixed extrusion plate 15 and the movable extrusion plate 16.

[0043] The first trigger switch 17 is located directly above the movable extrusion plate 16, and the second trigger switch 18 is located directly above one end of the fixed extrusion plate 15.

[0044] During equipment operation, as the intake air temperature inside the heating box 6 changes, the temperature control mechanism begins to function. When the intake air temperature in the heating box 6 rises, the gas inside the lower end of the pressure cylinder 12 expands due to heat and pushes the piston plate 13 upward. The piston plate 13 drives the fixed extrusion plate 15 to rise via the linkage rod 14. Since a spring connects the fixed extrusion plate 15 and the movable extrusion plate 16, the movable extrusion plate 16 is displaced by the spring as the fixed extrusion plate 15 rises. When the intake air temperature rises to a certain level, the movable extrusion plate 16 rises and touches the first trigger switch 17. At this time, the first trigger switch 17 sends a signal. After receiving the signal, the control circuit reduces the power of the heating element 7, thereby reducing heat output. This prevents the temperature inside the heating box 6 from becoming too high. When the inlet air temperature continues to rise, the fixed extrusion plate 15 continues to move upward relative to the movable extrusion plate 16 until one end of the fixed extrusion plate 15 touches the second trigger switch 18. The second trigger switch 18 sends a signal, and after receiving the signal, the control circuit further reduces the power of the heating tube 7. In this way, the temperature control mechanism can monitor the inlet air temperature in the heating box 6 in real time and automatically adjust the power of the heating tube 7 according to the temperature change, so that the temperature inside the heating box 6 is always kept within a suitable range for drying and setting the tape. This not only ensures product quality but also further optimizes the energy-saving effect of the equipment. Working in conjunction with the recirculation mechanism, it greatly improves the performance and stability of the entire energy-saving tape drying and setting equipment.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
