Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum transfer film production equipment, and in particular to a release agent drying device for electroplated aluminum transfer film processing. Background Technology

[0002] In the processing of electroplated aluminum transfer film, the release agent drying equipment is one of the key pieces of equipment. Electroplated aluminum transfer film, also known as hot stamping film or heat transfer film, is a material used for decoration and marking, and is widely used in packaging, printing, and gift industries. In the production process of electroplated aluminum transfer film, releasing agent drying is a crucial step in ensuring the quality of the transfer film.

[0003] First, the release agent is evenly coated onto the substrate of the electroplated aluminum film. After coating, pre-drying is usually required to remove solvent or moisture and allow the release agent to initially cure. After pre-drying, the film is sent to the main drying equipment for further drying. The temperature of the main drying stage is usually high to ensure that the release agent is completely cured.

[0004] However, existing release agent drying equipment for electroplated aluminum transfer film processing can only achieve a good drying effect on one side of the transfer film, resulting in poor overall drying effect. In addition, water vapor is generated during the drying process, and some drying devices are sealed, so the internal heat dissipates slowly after drying. Therefore, a release agent drying device for electroplated aluminum transfer film processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a release agent drying device for electroplated aluminum transfer film processing, aiming to improve the problems of poor overall drying effect of electroplated aluminum transfer film and slow heat dissipation rate in the drying oven after drying in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a release agent drying device for electroplated aluminum transfer film processing, comprising a drying chamber, wherein a plurality of ventilation holes are provided at the front end of the drying chamber, and an opening and closing assembly is provided at the front end of the drying chamber, the opening and closing assembly covering or exposing the ventilation holes; an inlet groove and an outlet groove are respectively provided at the middle of the left and right ends of the drying chamber; two connecting blocks are fixedly connected to the middle of the bottom side of the interior of the drying chamber at both the front and back, and two rollers are rotatably connected between the two connecting blocks; two connecting blocks are fixedly connected to the top side of the interior of the drying chamber at both the front and back, and two sets of two front and back connecting blocks are fixedly connected to the top of the interior of the drying chamber at both the left and right ends. Rollers are rotatably connected to each of the connecting blocks. A transfer film body is installed in the inlet groove. The right end of the transfer film body passes through the inlet groove and successively passes around the top of the left roller, the bottom of the bottom roller, and the top of the right roller before exiting through the outlet groove. Heating components are installed in the middle of the top and the left and right sides of the bottom of the drying chamber. The heating components are used to dry the release agent on the transfer film body. An air supply component is installed at the top of the drying chamber. The bottom left and right sides of the air supply component pass through the top of the drying chamber and are located on opposite sides of the two rollers. The air supply component blows hot air downwards from the top.

[0007] As a further description of the above technical solution: the opening and closing assembly includes a bidirectional lead screw and a ventilation hole. The left and right ends of the bidirectional lead screw and the ventilation hole are rotatably connected to fixed blocks. The rear ends of the four fixed blocks are fixedly connected to the front end of the drying chamber. The right end of the bidirectional lead screw is fixedly connected to the right end of the right fixed block. The left and right ends of the bidirectional lead screw and the slide rod are respectively provided with a moving plate 1 and a moving plate 2. The right end of the moving plate 1 has a slot in the middle. The left end of the moving plate 2 is fixedly connected to a locking block. The upper and lower ends of the moving plate 1 and the moving plate 2 are fixedly connected to sliders on opposite sides. The middle of the two upper sliders is threaded to the outer side of the bidirectional lead screw.

[0008] As a further description of the above technical solution: the middle parts of the two lower sliders are slidably connected to the slide rod, the locking block and the locking slot engage, and the locking block and the locking slot can completely cover the ventilation hole when engaged.

[0009] As a further description of the above technical solution: the heating assembly includes a heating plate, the bottom ends of the two lower heating plates are fixedly connected to the bottom of the interior of the drying chamber, the top end of the upper heating plate is fixedly connected to the top of the interior of the drying chamber, and five connecting posts are fixedly connected at equal intervals inside the heating plate, and heating wires are wound around the outside of the five connecting posts.

[0010] As a further description of the above technical solution: the air supply assembly includes two rows of rotating shafts, a synchronous belt, and a second motor. Each row of rotating shafts has six shafts. The two rows of rotating shafts are located on the left and right sides of the top heating plate and are rotatably connected to the drying chamber. Several blades are fixedly connected at equal intervals on the outer side of the bottom end of each rotating shaft. A synchronous pulley is fixedly connected to the outer side of the top end of each rotating shaft. The outer side of each synchronous pulley is meshed with the inner side of the synchronous belt. The top of the rear end of the left row of rotating shafts is fixedly connected to the output end of the second motor.

[0011] As a further description of the above technical solution: a support base is fixedly connected to the outside of the second motor, and the bottom of the support base is fixedly connected to the top of the drying chamber.

[0012] As a further description of the above technical solution: the synchronous pulleys are not meshed with each other.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when heating the inside of the drying chamber with electric heating wire, starting motor two causes the synchronous wheel to drive all rotating shafts and blades to rotate, blowing hot air from the top downwards, so that the upper and lower sides of the transfer film body are heated evenly, solving the problem that some drying equipment can only achieve a good drying effect on one side of the transfer film, resulting in poor overall drying effect.

[0014] 2. In this utility model, starting motor one causes the card block to disengage from the card slot, exposing the ventilation hole. Then starting motor two causes the blades to rotate, accelerating the airflow in the drying chamber and enabling the drying chamber to dissipate heat and exchange air more quickly.

[0017] 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.

[0018] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a release agent drying device for electroplated aluminum transfer film processing, comprising a drying chamber 1. The front end of the drying chamber 1 has several ventilation holes 11. An opening and closing assembly is provided at the front end of the drying chamber 1, which either covers or exposes the ventilation holes 11. An inlet groove 12 and an outlet groove 13 are respectively provided at the middle of the left and right ends of the drying chamber 1. Connecting blocks 2 16 are fixedly connected to the front and rear of the middle of the bottom side inside the drying chamber 1. A roller 2 17 is rotatably connected between two connecting blocks 2 16. Connecting blocks 14 are fixedly connected to the front and rear of the left and right ends of the top side inside the drying chamber 1. Two sets of two front and rear connecting blocks 14 are rotatably connected between each other. A roller 15 is connected to the moving connection. A transfer film body 18 is installed in the inlet groove 12. The right end of the transfer film body 18 passes through the inlet groove 12 and successively passes around the top of the left roller 15, the bottom of the bottom roller 17, and the top of the right roller 15 before exiting through the outlet groove 13. Heating components are installed in the middle of the top of the interior of the drying chamber 1 and on both the left and right sides of the bottom of the interior of the drying chamber 1. The heating components are used to dry the release agent on the transfer film body 18. An air supply component is installed at the top of the drying chamber 1. The bottom left and right sides of the air supply component pass through the top of the drying chamber 1 and are located on opposite sides of the two rollers 15. The air supply component blows the hot air from the top downwards.

[0019] The opening and closing mechanism prevents hot air from escaping from the drying chamber 1 when drying the release agent on the transfer film body 18. After drying is completed, the opening and closing mechanism is opened to allow the hot air to dissipate more quickly. As the hot air rises, the combination of the drying mechanism and the air supply mechanism can blow the hot air down from the top, drying the release agent at the top and bottom of the transfer film body 18 and preventing the top of the transfer film body 18 from being incompletely dried, thus reducing the drying efficiency of the release agent.

[0020] Reference Figure 1 The opening and closing assembly includes a bidirectional lead screw 3 and a ventilation hole 11. Fixed blocks 2 are rotatably connected to both ends of the bidirectional lead screw 3 and the ventilation hole 11. The rear ends of the four fixed blocks 2 are fixedly connected to the front end of the drying chamber 1. A motor 5 is fixedly connected to the right end of the right fixed block 2. A movable plate 6 and a movable plate 8 are respectively provided at the left and right ends between the bidirectional lead screw 3 and the slide rod 4. A slot 7 is opened in the middle of the right end of the movable plate 6. A locking block 9 is fixedly connected to the middle of the left end of the movable plate 8. Slider 10 is fixedly connected to the upper and lower ends of the movable plate 6 and the movable plate 8 on opposite sides. The middle of the two upper sliders 10 is threaded to the outer side of the bidirectional lead screw 3. The middle of the two lower sliders 10 is slidably connected to the slide rod 4. The locking block 9 and the slot 7 engage. When the locking block 9 and the slot 7 engage, the ventilation hole 11 can be completely covered.

[0021] During heating, the motor 5 is started, causing the moving plate 6 and the moving plate 8 to move towards the center of the drying chamber 1 until the locking block 9 can be locked in the slot 7, preventing the hot air inside the drying chamber 1 from escaping through the ventilation hole 11. After drying is completed, the motor 5 is started, causing the moving plate 6 and the moving plate 8 to move to the left and right ends of the drying chamber 1 respectively, causing the locking block 9 to disengage from the slot 7, exposing the ventilation hole 11, so that the inside of the drying chamber 1 can be ventilated more quickly.

[0022] Reference Figure 2 and Figure 3 The heating assembly includes a heating plate 19. The bottom ends of the two lower heating plates 19 are fixedly connected to the bottom of the interior of the drying chamber 1, and the top end of the upper heating plate 19 is fixedly connected to the top of the interior of the drying chamber 1. Five connecting posts 20 are fixedly connected at equal intervals inside the heating plate 19, and electric heating wires 21 are wound around the outside of each of the five connecting posts 20.

[0023] Heating with heating wire 21 allows the heat radiating from the heating plate 19 to be transferred out, filling the drying chamber 1 with hot air to dry the release agent on the transfer film body 18.

[0024] Reference Figure 1 , Figure 2 and Figure 4The air supply assembly includes two rows of rotating shafts 23, a synchronous belt 25, and a second motor 27. There are six rotating shafts 23 in one row. The two rows of rotating shafts 23 are located on the left and right sides of the top heating plate 19 and are rotatably connected to the drying chamber 1. Several blades 26 are fixedly connected at equal intervals on the outer side of the bottom end of the rotating shafts 23. Synchronous pulleys 24 are fixedly connected to the outer side of the top end of the rotating shafts 23. The outer side of the synchronous pulleys 24 are meshed with the inner side of the synchronous belt 25. The top of the rear rotating shafts 23 in the left row is fixedly connected to the output end of the second motor 27. A support base 22 is fixedly connected to the outer side of the second motor 27. The bottom of the support base 22 is fixedly connected to the top of the drying chamber 1. The synchronous pulleys 24 are not meshed with each other.

[0025] By starting motor 27, the rotating shaft 23 and synchronous pulley 24 at the left rear end are rotated, which causes the synchronous belt 25 to be displaced, thereby driving the other synchronous pulleys 24 to rotate, which in turn causes all rotating shafts 23 to drive the blades 26 to rotate, blowing the hot air from the top downwards.

[0026] Working principle: First, the right end of the transfer film body 18 is passed through the inlet groove 12 and then passes around the top of the left roller 15, the bottom of the bottom roller 27, and the top of the right roller 15 in sequence before exiting through the outlet groove 13. Then, motor 15 is started, causing moving plate 16 and moving plate 28 to move towards the center of the drying chamber 1 until the locking block 9 can engage with the locking groove 7, covering the ventilation hole 11. Then, the heating wire 21 is used to heat the inside of the drying chamber 1. The transfer film body 18 is displaced and wound up by the drive device. During the drying process, motor 27 is started, and all synchronous wheels 24 drive all rotating shafts 23 and blades 26 to rotate, blowing the hot air from the top downwards so that the upper and lower sides of the transfer film body 18 are heated evenly. After drying is completed, motor 15 is started to expose the ventilation hole 11, and motor 27 is started to quickly dissipate heat from the drying chamber 1.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
