Description

Technical Field

[0001] This utility model relates to the field of lens reflective film drying technology, specifically a lens reflective film dryer. Background Technology

[0002] Reflective coating is a special film layer coated on the surface of eyeglasses. It is mainly used to reduce the reflection of the eyeglasses and the reflection of the lens. Its main principle is to use multi-layer optical coating technology to form high-reflection and low-reflection layers on the lens surface, thereby reducing glare and reflection.

[0003] In the prior art, patent publication number CN219494719U discloses a reflective film drying device, including a machine shell, a film winding mechanism, an electric heating element, a longitudinal adjuster, an exhaust gas filter layer, and a circulating filter mechanism. The machine shell has a drying chamber internally formed and symmetrically has guide openings at both ends. Blinding blades are installed at the guide openings. The film winding mechanism is located at the rear of the machine shell and includes a mounting frame and a winding roller mounted on the mounting frame. One end of the winding roller is connected to a drive motor. The electric heating element is divided into two groups, located above and below the guide openings respectively. The motor heating element consists of several groups of electric heating rods. The electric heating rods in the dry assembly are connected by wiring. The longitudinal adjusters are divided into four groups. Four guide grooves are opened on the inner wall of the two symmetrical groups of the drying chamber. The four groups of longitudinal adjusters are respectively set in the four guide grooves. The two symmetrical groups of longitudinal adjusters are connected to both ends of the electric heating element. The exhaust gas filter layer is set above the drying chamber. An L-shaped partition is installed in the upper left corner of the drying chamber and an exhaust fan is installed in the upper right corner. A diversion pipe is installed on the exhaust fan. A valve is installed on the diversion pipe and a formaldehyde concentration sensor is built into it. The side of the diversion pipe is connected to the circulating filter mechanism. The end of the circulating filter mechanism is located inside the L-shaped partition.

[0004] The following are the disadvantages of this type of lens reflective film dryer: when drying the lens reflective film, the reflective film enters the interior of the machine body from the left side of the machine body for drying, and after drying, it is conveyed out from the right side of the machine body for winding. This type of dryer is large in size, occupies a large area, and wastes work space. In addition, the travel of the reflective film conveyor during drying is not adjustable, resulting in poor flexibility of use. Therefore, we propose a lens reflective film dryer. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a lens reflective film dryer. The reflective film changes its travel direction twice inside the drying chamber by two rotating rollers, thereby ensuring that the volume of the drying chamber is smaller and more space-saving under the same conveying stroke. Moreover, the conveying stroke of the lens reflective film can be adjusted, making it more flexible to use and effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens reflective film dryer, including a drying chamber, a drying chamber door hinged to the front side of the drying chamber, and a drying mechanism;

[0007] The drying mechanism includes a sliding column one, a sliding seat, a sliding column two, a slider, a rotating roller, a connecting rod, and a connecting plate.

Sliding columns two are symmetrically distributed between the left and right side walls of the drying chamber. Sliding blocks are slidably connected to the middle of the outer surface of each sliding column two. A rotating roller is rotatably connected to the front side of each slider. Connecting rods are symmetrically distributed on the right sides of the upper and lower ends of the sliding seat. Connecting plates are located on the relatively inner sides of each slider. The connecting rods are slidably connected to the threaded holes in the middle of the longitudinally adjacent connecting plates. The reflective film changes its travel direction twice inside the drying chamber via two rotating rollers, thus ensuring a smaller volume of the drying chamber and saving more space under the same conveying stroke. Furthermore, the conveying stroke of the reflective film is adjustable, providing greater flexibility in use.

[0008] Furthermore, a control switch assembly is provided on the front side of the drying chamber door, and the input end of the control switch assembly is electrically connected to an external power source to control electrical appliances.

[0009] Furthermore, the drying mechanism also includes a mounting plate and heating rods. The mounting plate is located in the middle of the front side of the sliding seat, and the heating rods are all located on the right side of the mounting plate. The input end of the heating rods is electrically connected to the output end of the control switch group to dry the reflective film of the lens.

[0010] Furthermore, the outer surface of the connecting rod is provided with evenly distributed locking holes, and the threaded holes on the front side of the connecting plate are threaded with locking screws. The locking screws are installed in conjunction with the longitudinally adjacent locking holes to lock the connecting plate.

[0011] Furthermore, a lead screw is rotatably connected between the left and right side walls of the drying chamber. The lead screw is threadedly connected to the threaded hole in the middle of the sliding seat. A motor is installed in the middle of the right side wall of the drying chamber. The output shaft of the motor passes through the round hole in the middle of the right side wall of the drying chamber and is fixedly connected to the right side of the lead screw. The input end of the motor is electrically connected to the output end of the control switch group to adjust the stroke of the reflective film of the lens in the drying chamber.

[0012] Furthermore, a discharge port is provided at the upper end of the right side wall of the drying chamber, and a feed port is provided at the lower end of the right side wall of the drying chamber, which facilitates the drying of the reflective film on the lens.

[0013] Furthermore, the upper right side wall of the drying chamber is provided with symmetrically distributed mounting plates, and a winding roller is rotatably connected between the two mounting plates. A second motor is provided at the rear end of the mounting plate located on the rear side. The output shaft of the second motor passes through the round hole two at the rear end of the mounting plate located on the rear side and is fixedly connected to the rear side of the winding roller. The input end of the second motor is electrically connected to the output end of the control switch group to wind up the dried reflective film of the lens.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This lens reflective film dryer has the following advantages:

[0015] By changing the direction of travel of the reflective film in the drying chamber through the rotating roller, the travel distance is increased while making the drying chamber smaller and saving more space in the work area. The travel distance of the reflective film inside the drying chamber is adjusted by adjusting the distance between the rotating roller and the discharge port, thereby changing the drying time of the reflective film inside the drying chamber and achieving the best drying effect. According to the drying requirements of the reflective film, its travel distance in the drying chamber can be adjusted to extend its drying time and achieve the best drying effect, which saves space and makes it more flexible in use.

[0016] 1. The reflective film changes its travel direction twice inside the drying chamber via two rotating rollers, thus ensuring that the drying chamber is smaller and saves more space under the same conveying stroke.

[0017] 2. The sliding seat slides along the sliding column to the left side of the drying chamber, which drives the two sliders to drive the rotating roller to slide to the left side of the drying chamber, thus making the length of the lens reflective film in the drying chamber longer, thereby increasing the travel of the lens reflective film. Moreover, the travel of the lens reflective film can be adjusted, making it more flexible to use. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-3 This embodiment provides a technical solution: a lens reflective film dryer, including a drying chamber 1, a drying chamber door 2 hinged to the front of the drying chamber 1, and a drying mechanism 4. A control switch group 3 is provided on the front of the drying chamber door 2, the input end of the control switch group 3 is electrically connected to an external power source, and evenly distributed locking holes 9 are provided on the front of the outer surface of the connecting rod 48. Locking screws 10 are threaded into the threaded holes on the front of the connecting plate 49, and the locking screws 10 are installed in conjunction with the longitudinally adjacent locking holes 9. A lead screw 7 is rotatably connected between the middle of the left and right side walls of the drying chamber 1, and the lead screw 7 is threaded into the threaded hole in the middle of the sliding seat 42. The middle of the right side wall of the drying chamber 1 is... A motor 8 is provided, and the output shaft of the motor 8 passes through the round hole in the middle of the right side wall of the drying chamber 1 and is fixedly connected to the right side of the lead screw 7. The input end of the motor 8 is electrically connected to the output end of the control switch group 3. A discharge port 5 is opened at the upper end of the right side wall of the drying chamber 1, and a feed port 6 is opened at the lower end of the right side wall of the drying chamber 1. A symmetrically distributed mounting plate is provided at the upper end of the right side wall of the drying chamber 1. A winding roller 11 is rotatably connected between the two mounting plates. A motor 12 is provided at the rear end of the mounting plate located on the rear side. The output shaft of the motor 12 passes through the round hole 2 at the rear end of the mounting plate located on the rear side and is fixedly connected to the rear side of the winding roller 11. The input end of the motor 12 is electrically connected to the output end of the control switch group 3.

[0024] Drying mechanism 4 includes a sliding column 41, a sliding seat 42, a sliding column 43, a slider 44, a rotating roller 45, a connecting rod 48, and a connecting plate 49. A sliding column 41 is located in the middle between the left and right side walls of the drying chamber 1. A sliding seat 42 is slidably connected to the middle of the outer surface of the sliding column 41. Two sliding columns 43 are symmetrically distributed between the left and right side walls of the drying chamber 1. A slider 44 is slidably connected to the middle of the outer surface of each sliding column 43. A rotating roller 45 is rotatably connected to the front side of each slider 44. Connecting rods 48 are symmetrically distributed on the right sides of the upper and lower ends of the sliding seat 42. A connecting plate 49 is located on the inner side of each slider 44. The connecting rods 48 are slidably connected to the threaded holes in the middle of the longitudinally adjacent connecting plates 49. The drying mechanism 4 also includes a mounting plate 46 and heating rods 47. The mounting plate 46 is located in the middle of the front side of the sliding seat 42. The heating rods 47 are located on the right side of the mounting plate 46. The input end of the heating rod 47 is electrically connected to the output end of the control switch group 3, and then controlled by the switch... When switch group 3 is activated, heating rod 47 emits heat to dry the reflective film on the lens. Then, the travel of the reflective film inside the drying chamber 1 is adjusted according to the drying time required. By controlling switch group 3, motor 8 is activated. Motor 8 drives screw 7 to rotate and drives sliding seat 42 to move heating rod 47 to the left along slide column 41. At the same time, connecting rod 48 pushes connecting plate 49 to drive slider 44 and rotating roller 45 to slide synchronously, thereby maintaining the distance between heating rod 47 and reflective film and preventing contact between heating rod 47 and reflective film. Then, motor 12 can be activated by controlling switch group 3. Motor 12 drives take-up roller 11 to rotate and take-up reflective film. The reflective film changes its travel direction twice inside the drying chamber 1 by passing through two rotating rollers 45, thus ensuring that the volume of drying chamber 1 is smaller and more space-saving under the same conveying travel. Moreover, the conveying travel of reflective film can be adjusted, making it more flexible to use.

[0025] The working principle of the lens reflective film dryer provided by this utility model is as follows: When drying the lens reflective film, the lens reflective film needs to be inserted from the feed port 6 to the left, passing through the outer surface of the lower rotating roller 45 upwards, then passing through the outer surface of the upper rotating roller 45 and exiting to the right, and then exiting from the discharge port 5. The end of the lens reflective film exiting the discharge port 5 is wrapped and fixed to the outer surface of the take-up roller 11. Then, the heating rod 47 is turned on by the control switch group 3. The heating rod 47 emits heat to dry the lens reflective film. Then, the stroke of the lens reflective film inside the drying chamber 1 is adjusted according to the drying time required for the lens reflective film. The motor 8 is turned on by the control switch group 3. The motor 8 drives the lead screw 7 to rotate and the transmission sliding seat 42 drives the heating rod 47 to slide to the left along the slide column 41. At the same time, the connecting rod 48 pushes the connecting plate. 49 drives slider 44 to drive rotating roller 45 to slide synchronously, thereby adjusting the movement of the two rotating rollers 45 to the left or right in the drying chamber 1, thereby adjusting the length of the lens reflective film inside the drying chamber 1 (the more the two rotating rollers 45 are inside the drying chamber 1 on the left, the longer the lens reflective film inside the drying chamber 1; the more the two rotating rollers 45 are inside the drying chamber 1 on the right, the shorter the lens reflective film inside the drying chamber 1). This allows adjustment of the travel of the lens reflective film inside the drying chamber 1. During this process, the distance between the heating rod 47 and the two rotating rollers 45 is constant, so the distance between the lens reflective film and the heating rod 47 will also remain unchanged, thus preventing the heating rod 47 from contacting the lens reflective film. Then, the motor 12 can be turned on by controlling switch group 3, and the motor 12 drives the winding roller 11 to rotate and wind up the lens reflective film.

[0026] It is worth noting that the second motor 12 disclosed in the above embodiments can be SB-7.5 / 380Y, the heating rod 47 can be WATLOW, the first motor 8 can be a 110BYGH1.8 two-phase stepper motor, and the control switch group 3 is provided with buttons that correspond one-to-one with the second motor 12, the heating rod 47 and the first motor 8 and control their switching.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
