Description

Technical Field

[0001] This utility model relates to the field of heating film drying technology, specifically a drying device for heating film production. Background Technology

[0002] In the production process of heating films, drying is a crucial step in ensuring product quality, directly affecting the performance stability and service life of the heating film. Existing drying equipment used in heating film production suffers from uneven drying during operation.

[0003] Existing devices often use a single air duct or a simple blowing structure to deliver hot air, making it difficult to control the distribution of hot air within the oven. This results in significant differences in the amount of airflow and heat received by the heating film at different locations. The upper heating film often dries rapidly due to excessive airflow, sometimes even leading to localized overheating and damage; while the lower heating film dries slowly due to insufficient airflow, making it prone to incomplete drying and affecting the overall quality consistency of the heating film. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for heating film production.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drying device for producing heating film includes: a metal tube heater and a drying chamber. A square pipe is installed through the right wall of the metal tube heater, and an L-shaped pipe is installed through the top of the metal tube heater. The other ends of the square pipe and the L-shaped pipe are connected to the drying chamber. A support plate is installed inside the drying chamber, and multiple sets of fans are fixedly installed on the support plate. A servo motor is installed on the shaft of each set of fans. A reversing bending plate is installed on the right inner wall of the drying chamber. Multiple sets of heating film supports are installed below the support plate inside the drying chamber, and a baffle plate assembly is installed on the rightmost heating film support.

[0007] The wind deflector assembly has baffles arranged from short to long from top to bottom. The left side of each baffle is fixed to the right side bracket of the heating film bracket. The wind deflector assembly is used to make the air volume decrease from top to bottom, so as to realize the air volume circulation from top to bottom. The heating film bracket is used to hold multiple sets of heating films.

[0008] The reversing bend is used to redirect the airflow from left to right on the upper part of the support plate to flow from top to bottom onto the baffle assembly; the metal tube heater is used to heat the airflow from the drying chamber into the square duct; the fan is used to deliver the heated air from the L-shaped duct to the reversing bend.

[0009] Preferably, the heating film support includes: a frame-type support, with multiple sets of supporting crossbars evenly spaced between the frames of the frame-type support, and casters at the four bottom corners of the frame-type support. The supporting crossbars are used to place the heating film; the casters are used to move the frame-type support.

[0010] Preferably, a square door is hinged to the front of the drying chamber, and the size of the square door is sufficient for at least two sets of frame supports to enter. A ramp is provided on the outer bottom plate of the drying chamber for the frame supports to enter.

[0011] A square through hole 1 is provided at the bottom left side of the drying chamber, and a square through hole 2 is provided at the top left side of the drying chamber. The square through hole 1 is connected to one end of a square pipe, and the square through hole 2 is connected to one end of an L-shaped through hole.

[0012] Preferably, an activated carbon frame is provided in the center of the top plate of the drying chamber, which is used to absorb water vapor carried in the hot air.

[0013] Compared with the prior art, the present invention provides a drying device for heating film production, which has the following beneficial effects:

[0014] The baffle assembly features baffles arranged in ascending order of length from top to bottom, with each baffle fixed to the right side of the heating film bracket on its left side. This structural design precisely achieves a decreasing airflow from top to bottom. Combined with the reversing bend plate that redirects the airflow from the upper part of the support plate to the baffle assembly, and the fan's function of delivering hot air, a stable airflow circulation from top to bottom is formed.

[0015] This design and circulation mode, characterized by decreasing airflow, allows for differentiated airflow to multiple layers of heating film, ensuring that each layer receives an appropriate airflow. This effectively avoids the inconsistent drying results caused by uneven airflow distribution in traditional drying devices. The upper heating film is prevented from over-drying due to excessive airflow, while the lower heating film remains dry despite insufficient airflow, thus improving the uniformity of drying and ensuring product quality stability.

[0020] 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.

[0021] Reference Figures 1-3 As shown, a drying device for producing heating film in this embodiment includes a drying chamber 1 and a metal tube heater 2. The bottom left side of the drying chamber 1 is connected to the right wall of the metal tube heater 2 through a square pipe 3, and the top of the metal tube heater 2 is connected to the top left side of the drying chamber 1 through an L-shaped pipe 4 to form a hot air circulation channel.

[0022] A support plate 103 is horizontally installed inside the drying chamber 1. Multiple fans 7 with servo motors are fixed on the upper surface of the support plate 103, and the fans 7 provide power for hot air circulation. An arc-shaped reversing plate 104 is fixed on the right inner wall of the drying chamber 1. Multiple heating film supports 6 are placed parallel below the support plate 103. A baffle assembly 8 is installed on the right side of the rightmost heating film support 6.

[0023] The heating film support 6 adopts a frame-type support 601 structure, with crossbars 603 evenly distributed between the frames, and casters 602 installed at the four corners of the bottom. The wind deflector assembly 8 consists of multiple baffles of varying lengths, which are fixed sequentially from top to bottom on the right side of the heating film support 6 to achieve a gradient decrease in airflow.

[0024] The drying chamber 1 has a hinged square door 101 on the front side, and the outer bottom plate has a ramp 102 to facilitate the entry and exit of the heating film support 6. An activated carbon frame 5 is embedded in the center of the top plate to adsorb water vapor in the hot air.

[0025] In some examples, both the square pipe 3 and the L-shaped pipe 4 have heat insulation layers attached to their inner walls. The heat insulation layers can reduce the heat loss of the hot air inside the pipe, improve heating efficiency, and reduce the energy consumption of the metal pipe heater 2.

[0026] In some examples, the baffle of the wind deflector assembly 8 is made of high-temperature resistant silicone material, which has good flexibility and aging resistance, and can maintain shape stability under long-term high temperature environment to ensure long-lasting and reliable airflow regulation effect.

[0027] In some examples, the surface of the support crossbar 603 is coated with a Teflon coating. The Teflon coating is non-stick and can prevent the heating film from sticking to the surface of the crossbar due to high temperature during the drying process, thus avoiding damage to the heating film.

[0028] In some examples, a magnetic sealing strip is installed on the edge of the square door 101 that contacts the drying chamber 1. The magnetic sealing strip can enhance the sealing performance of the door after it is closed, prevent hot air from leaking out, and facilitate the quick opening and closing of the door.

[0029] The working principle of this utility model is as follows:

[0030] Lay the heating film to be dried evenly from top to bottom on the support crossbar 603 of the heating film bracket 6, ensuring that the heating film is evenly spread and does not overlap. Open the square door 101 on the front side of the drying chamber 1, and use the casters 602 at the bottom of the frame bracket 601 to push the bracket with the laid heating film along the slope 102 of the outer bottom plate into the drying chamber 1. Among them, the heating film bracket with the wind baffle assembly 8 on the right side should be accurately placed directly below the reversing bend plate 104 on the right inner wall of the drying chamber 1, and the remaining brackets should be arranged to the left in sequence. Close the square door 101, and ensure the airtightness of the chamber by the magnetic sealing strip on the edge of the door.

[0031] When starting the equipment, the operator simultaneously turns on the fan 7 on the support plate 103 and the metal tube heater 2. The fan 7 starts running under the drive of the servo motor, and the metal tube heater 2 enters the working state to prepare to heat the air. At this time, the airflow in the drying chamber 1 forms a directional flow under the action of the fan 7: the hot air moves from left to right from the top space of the support plate 103, and when it comes into contact with the reversing bend plate 104 on the right inner wall, the airflow direction is guided to be from top to bottom, vertically entering the area of ​​the baffle assembly 8.

[0032] The baffle assembly 8, with its baffle structure increasing in size from top to bottom, ensures a gradual decrease in airflow into each layer of the heating film support 6. The upper heating film receives a moderate amount of airflow to avoid over-drying, while the lower heating film receives an appropriate amount of airflow to ensure thorough drying. The airflow carrying water vapor continues to move to the left after passing through the heating film layers, entering the square pipe 3 through the square through-hole 302 at the bottom left side of the drying chamber 1. It then flows into the metal pipe heater 2 for secondary heating. The heated air is then transported back to the square through-hole 2 at the top left side of the drying chamber 1 via the L-shaped pipe 4, returning to the support plate 103 to complete one cycle. This process is repeated continuously to achieve continuous drying.

[0033] During continuous operation, the activated carbon frame 5 in the center of the top plate of the drying chamber 1 continuously adsorbs water vapor from the hot air, maintaining a dry environment inside the chamber. When maintenance is required, first turn off the fan 7 and the metal tube heater 2. After the temperature inside the chamber drops to room temperature, open the square door 101 and move the heating film bracket 6 out along the ramp 102 using the casters 602. This allows for cleaning of the Teflon coating on the surface of the support crossbar 603. Regularly replace the adsorption material inside the activated carbon frame 5 and check the insulation layer on the inner walls of the square pipe 3 and the L-shaped pipe 4 to ensure long-term stable operation of the equipment.

[0034] 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.
