Description

Technical Field

[0001] This utility model belongs to the technical field of drying and heating equipment, specifically relating to an electric heating constant temperature drying oven for release film processing. Background Technology

[0002] The electric constant temperature drying oven for release film processing is a precision temperature control device designed specifically for the production and subsequent processing of release film. It is mainly used for key process steps such as drying, curing and moisture removal after release film coating. It adopts a high-efficiency electric heating system and intelligent PID temperature control technology to ensure that the release film is heated evenly and without thermal stress deformation during the drying process, while avoiding the instability of coating performance caused by temperature fluctuations.

[0003] Currently, dust accumulation inside the air duct is an easily overlooked problem in the operation of electric constant temperature drying ovens. During long-term use, the substances volatilized from the release film will gradually accumulate inside the air duct, especially forming a stubborn dust layer in the dead corners of the airflow, which will significantly hinder the normal circulation of hot air and lead to a decrease in the working efficiency of the drying oven. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1-5 This is an embodiment of the present invention, which provides an electrically heated constant-temperature drying oven for release film processing, comprising:

[0030] The heating mechanism 100 includes a housing 110, a drive motor 120 fixedly installed on the top of the housing 110, and a tube 130 fixedly installed on the outside of the housing 110.

[0031] The connecting mechanism 200 includes a storage box 210, a connecting pipe 220 fixedly installed on the outside of the storage box 210, a dust removal component 230 disposed in the inner cavity of the connecting pipe 220, and a dust sweeping component 240 used in conjunction with the dust removal component 230.

[0032] The modular design facilitates maintenance by setting up an independent heating mechanism 100 and a connecting mechanism 200. The fixed connection between the drive motor 120 and the housing 110 ensures stable power transmission, while the dust removal component 230 and the dust sweeping component 240 in the connecting pipe 220 work together to regularly clean the dust accumulated in the air duct and avoid a decrease in thermal efficiency.

[0033] Specifically, the connecting mechanism 200 also includes a magnetic suction plate 250 fixedly installed in the inner cavity of the connecting tube 220, a through hole 260 opened at the bottom of the connecting tube 220, and a positioning component 270 disposed in the inner cavity of the through hole 260.

[0034] The magnetic plate 250 can adsorb metal dust, reducing impurities entering the fan 150. The through hole 260 cooperates with the positioning component 270 to realize the quick positioning and disassembly of the dust removal component 230, which facilitates manual dust removal operation and ensures that the sealing performance is not affected.

[0035] Furthermore, the dust removal assembly 230 includes a horizontal plate 231 movably mounted in the inner cavity of the through hole 260, a bearing seat 232 fixedly mounted on the top of the horizontal plate 231, a connecting rod 233 hinged to the top of the bearing seat 232, an adsorption plate 234 fixedly mounted on the outside of the connecting rod 233, a scraper 235 fixedly mounted on the bottom of the adsorption plate 234, and a magnetic strip 236 fixedly mounted on the outside of the scraper 235. One side of the connecting pipe 220 is fixedly connected to the outside of the housing 110 and they are interconnected. There are two bearing seats 232, which are evenly distributed on both sides of the top of the horizontal plate 231.

[0036] The dust removal component 230 adopts a hinged structure. When the handle 273 is pressed down, the connecting rod 233 drives the soft adsorption plate 234 and the scraper 235 to move down synchronously. The adsorption plate 234 adheres and carries away loose dust, while the scraper 235 scrapes away stubborn dust. The magnetic strip 236 further adsorbs metal debris, achieving multi-stage cleaning. The dual-axis seat 232 design improves the movement stability of the connecting rod 233 and ensures that the adsorption plate 234 is subjected to uniform force. The structure of the connecting pipe 220 directly connected to the box 110 simplifies the air duct layout and reduces airflow resistance.

[0037] Preferably, the dust removal assembly 240 includes a crossbar 241 fixedly installed in the inner cavity of the connecting pipe 220, a support rod 242 fixedly installed on the top of the crossbar 241, a rotating rod 243 hinged to the end of the crossbar 241, and a dust removal brush 244 fixedly installed on the end of the rotating rod 243.

[0038] The rotating rod 243 and the dust-sweeping brush 244 of the dust-sweeping component 240 rotate under the influence of airflow, actively cleaning the dust accumulated on the inner wall of the connecting pipe 220, forming a dynamic and static cleaning system with the dust-cleaning component 230.

[0039] Furthermore, the positioning component 270 includes a clamping plate 271 fixedly mounted on the bottom of the horizontal plate 231, screws 272 threaded around the bottom of the clamping plate 271, and a handle 273 fixedly mounted on the bottom of the clamping plate 271.

[0040] The screw 272 fixing plate 271 is designed for quick disassembly. The entire dust removal assembly 230 can be moved down by pulling down the handle 273, achieving tool-free maintenance and significantly reducing the difficulty of manual cleaning.

[0041] Furthermore, the heating mechanism 100 also includes a housing 140 fixedly installed inside the cavity of the housing 110, a fan 150 fixedly installed at the bottom of the housing 140, a heating pipe 160 fixedly installed outside the fan 150, and an air exchange pipe 170 fixedly installed outside the heating pipe 160.

[0042] The casing 140 integrates the fan 150 and the heating element 160, and the ventilation pipe 170 optimizes the hot air circulation path. The overall structure is compact, and with the cleaning function of the connecting mechanism 200, the thermal efficiency of the drying oven can be maintained for a long time.

[0043] In use, the heating mechanism 100 is started first, driving the motor 120 to drive the fan 150. The heat generated by the heating tube 160 forms circulating hot air through the ventilation pipe 170 and enters the box 110 to dry the release film. At the same time, when the hot air flows through the connecting pipe 220, it drives the rotating rod 243 of the dust sweeping component 240 to rotate the dust sweeping brush 244, continuously cleaning the dust accumulated on the pipe wall. When deep cleaning is required, loosen the screw 272 of the positioning component 270 and pull down the handle 273 to move the dust cleaning component 230 down as a whole. At this time, the adsorption plate 234 adheres to loose dust, the scraper 235 scrapes away stubborn dirt, and the magnetic strip 236 adsorbs metal debris. The three work together to thoroughly clean the inner cavity of the connecting pipe 220. After cleaning, push up the handle 273 to reset the dust cleaning component 230, tighten the screw 272 to fix it, and the magnetic plate 250 continues to adsorb metal impurities in the circulating airflow.

[0044] In summary, the modularly designed heating mechanism 100 and connecting mechanism 200 achieve efficient and stable hot air circulation and convenient maintenance. The housing 140 of the heating mechanism 100 integrates a fan 150, a heating tube 160, and an air exchange pipe 170 to form a compact heat exchange system. The connecting mechanism 200 achieves multi-stage dust removal through the dynamic and static coordination of the dust removal component 230 and the dust sweeping component 240. The dust removal component 230 adopts a combination structure of a hinged adsorption plate 234, a scraper 235, and a magnetic strip 236, which can simultaneously remove loose dust and stubborn dust when the handle 273 is pulled down. The rotating rod 243 of the dust sweeping component 240 drives the dust sweeping brush 244 to automatically rotate and sweep in the airflow. Combined with the metal adsorption function of the magnetic plate 250 and the quick disassembly and assembly design of the positioning component 270, it not only ensures unobstructed airflow and stable thermal efficiency, but also significantly reduces maintenance difficulty and downtime.
