Description

Technical Field

[0001] This utility model relates to the field of release film production technology, and in particular to an oven for release film production. Background Technology

[0002] Release film is a thin film whose main function is to be non-sticky or only slightly sticky when in contact with specific materials under certain conditions. Release films are widely used in electronics, IT displays, medical devices, home appliance manufacturing, anti-counterfeiting materials, semiconductors, automobiles, nameplates, ceramic sheet manufacturing, tape production, and die-cutting industries. Release films require drying during production, necessitating the use of specialized drying equipment.

[0003] Chinese utility model patent CN221649034U discloses a drying device for release film production. This device, through the cooperation of a long plate, a slide groove, a double-headed reverse lead screw, a motor, and a slider, can adjust the distance between two baffles located on the right side of the drying oven, thereby changing the size of the feed inlet to accommodate release films of different sizes. This avoids an excessively large feed inlet, reduces heat loss inside the drying oven, and improves the drying effect of the release film. Regarding the aforementioned related technology, the inventors believe the following defects exist:

[0004] In actual use, the water vapor generated during the drying of the release film will accumulate inside the oven. In addition, the device lacks an integrated structure to remove moisture from the inside of the oven, which easily leads to excessive humidity inside the device affecting the drying effect of the release film. Therefore, we provide an oven for the production of release film. Utility Model Content

[0005] To address the problem in the aforementioned background technology that the difficulty in removing moisture from the inside of the oven affects the drying effect on the release film, this utility model provides an oven for the production of release films.

[0006] This utility model is achieved by the following technical solution: a drying oven for release film production, including a drying box and a dehumidification component. The drying box has a film inlet and a film outlet on both sides. The film inlet and the film outlet are rotatably connected to the outside of the film inlet and the film outlet. Two sets of drying hot air blowers are symmetrically fixedly connected to the top of the drying box, and the air outlet of the drying hot air blowers is connected to the drying box.

[0007] The dehumidification assembly includes a U-shaped tube fixedly connected to the drying chamber. An exhaust fan is fixedly connected inside the inlet end of the U-shaped tube, and an exhaust fan is fixedly connected inside the outlet end of the U-shaped tube. A dehumidification box is fixedly connected to the U-shaped tube, and a fixed plate is fixedly connected inside the dehumidification box. A movable plate is provided on one side of the fixed plate. A water-absorbing sponge is added between the movable plate and the fixed plate, and the water-absorbing sponge is fixedly connected to the fixed plate. A motor is fixedly connected to the top of the dehumidification box. A disc is coaxially fixedly connected to the end of the rotor of the motor. A column is provided outside the disc. A frame is movably connected to the outside of the column. A connecting rod is fixedly connected to the frame, and the bottom end of the connecting rod extends into the interior of the dehumidification box. A connecting rod is symmetrically hinged between the end of the connecting rod and the movable plate through a hinge.

[0008] As a further improvement to the above solution, two sets of vertical rods are symmetrically slidably connected to the dehumidification box. The top ends of the two sets of vertical rods are fixedly connected to the same connecting plate one, and the bottom ends of the two sets of vertical rods are fixedly connected to the same connecting plate two. Springs are sleeved on the outside of the vertical rods. A drain outlet is opened on one side of the bottom of the dehumidification box. A baffle is movably connected to the outside of the drain outlet. A connecting rod two is symmetrically hinged between the baffle and the connecting plate two through a hinge. A rectangular slot is opened on the baffle, and a sealing gasket is added to the top of the baffle.

[0009] As a further improvement to the above solution, four sets of guide rods are symmetrically fixedly connected to one side of the movable plate, and the guide rods are slidably connected to the dehumidification box through a sealing ring. An anti-detachment plate is fixedly connected to the end of the guide rod.

[0010] As a further improvement to the above solution, both the movable plate and the fixed plate are provided with water-permeable holes evenly distributed.

[0011] As a further improvement to the above solution, the column is fixedly connected to the outside of the disk near the edge, and a limit plate is fixedly connected to the end of the column.

[0012] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the dehumidification box and the connecting plate 2, respectively.

[0013] As a further improvement to the above solution, the dehumidification box is symmetrically fixedly connected with guide grooves, and the baffle is symmetrically fixedly connected with guide sliders, and the guide sliders are slidably connected to the guide grooves on the same side.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses an exhaust fan to draw out the hot and humid air inside the drying chamber. The water-absorbing sponge absorbs the moisture and then discharges it back into the drying chamber through the exhaust fan, thereby reducing the humidity inside the drying chamber and ensuring the drying effect on the release film. Furthermore, a motor drives a rotating disc, which in turn causes the column rod to move in a circular motion. The movable cooperation between the column rod and the frame allows the connecting rod to move vertically back and forth. With the sliding cooperation between the guide rod and the dehumidification box, and the hinged cooperation between the movable plate and the connecting rod and the first connecting rod, the movable plate can be pushed back and forth to regularly squeeze the water-absorbing sponge, thereby squeezing out the moisture and maintaining its good water absorption effect. It is highly practical.

[0016] 2. When the connecting rod moves vertically downward, this utility model can push the two sets of vertical rods downward together. At this time, the spring will be stretched, and with the sliding cooperation between the guide slider and the guide groove, and the hinged cooperation between the baffle and the connecting plate and the connecting rod, the baffle can be driven to move horizontally. At this time, the rectangular groove on the baffle will gradually coincide with the drain outlet, thus facilitating the discharge of squeezed water. Conversely, when the connecting rod rises, the spring's own rebound action will cause the vertical rod to rise automatically, thus driving the baffle to return to its original position. At this time, the rectangular groove will be offset from the drain outlet to close it, thereby preventing heat loss and further improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1-4 This embodiment of a release film production oven includes a drying box 1. The drying box 1 has a film inlet and a film outlet on both sides. The film inlet and the film outlet are rotatably connected to the outside of a conveying roller 2. The top of the drying box 1 is symmetrically fixedly connected to two sets of drying hot air blowers 3, and the air outlet of the drying hot air blowers 3 is connected to the drying box 1.

[0026] A dehumidification assembly for reducing the humidity inside the drying oven 1 includes a U-shaped tube 101 fixedly connected to the drying oven 1. An exhaust fan 102 is fixedly connected inside the inlet end of the U-shaped tube 101, and an exhaust fan 103 is fixedly connected inside the outlet end of the U-shaped tube 101. A dehumidification box 104 is fixedly connected to the U-shaped tube 101. A fixed plate 105 is fixedly connected inside the dehumidification box 104. A movable plate 106 is provided on one side of the fixed plate 105. A water-absorbing sponge 107 is placed between the movable plate 106 and the fixed plate 105, and the water-absorbing sponge 107 is fixedly connected to the fixed plate 105. A motor is fixedly connected to the top of the dehumidification box 104. A disc 108 is coaxially fixedly connected to the end of the motor rotor. A column rod 109 is provided outside the disc 108. A frame 110 is movably connected to the outside of the column rod 109. A connecting rod 111 is fixedly connected to the frame 110, and the bottom end of the connecting rod 111 extends into the interior of the dehumidification box 104. A sealing ring is also provided at the sliding connection between the connecting rod 111 and the dehumidification box 104. A connecting rod 112 is symmetrically hinged between the end of the connecting rod 111 and the movable plate 106 through a hinge. Four sets of guide rods 4 are symmetrically fixedly connected to one side of the movable plate 106, and the guide rods 4 are slidably connected to the dehumidification box 104 through a sealing ring. An anti-detachment plate is fixedly connected to the end of the guide rod 4, which can play a certain guiding role in the horizontal movement of the movable plate 106. The column rod 109 is fixedly connected to the outside of the disc 108 near the edge, and a limit plate is fixedly connected to the end of the column rod 109.

[0027] Two sets of vertical rods 201 are symmetrically slidably connected to the dehumidifier box 104. The top ends of the two sets of vertical rods 201 are fixedly connected to the same connecting plate 1, and the bottom ends of the two sets of vertical rods 201 are fixedly connected to the same connecting plate 2. A spring 202 is sleeved on the outside of the vertical rods 201. The two ends of the spring 202 are fixedly connected to the dehumidifier box 104 and the connecting plate 2, respectively. A drain outlet is opened on one side of the bottom of the dehumidifier box 104. A baffle 203 is movably connected to the outside of the drain outlet. A connecting rod 204 is symmetrically hinged between the baffle 203 and the connecting plate 2 through a hinge. A rectangular slot is opened on the baffle 203. A sealing gasket is added to the top of the baffle 203. A guide groove is symmetrically fixedly connected to the dehumidifier box 104. A guide slider is symmetrically fixedly connected to the baffle 203 and is slidably connected to the guide groove on the same side, which can ensure that the baffle 203 can move horizontally stably.

[0028] The implementation principle of a release film production oven in this embodiment is as follows: the release film is inserted through the film inlet and exited through the film outlet. The conveyor roller 2 conveys the release film. The drying hot air blower 3 dries the release film passing through the drying oven 1. The exhaust fan 102 extracts the hot and humid air from the drying oven 1. The water-absorbing sponge 107 absorbs the moisture and then discharges it into the drying oven 1 through the exhaust fan 103, thereby reducing the humidity inside the drying oven 1 and ensuring the drying effect of the release film. The motor drives the disc 108 to rotate, which in turn drives the column rod 109 to perform circumferential motion. The movable cooperation between the column rod 109 and the frame 110 enables the connecting rod 111 to move vertically back and forth. Under the sliding cooperation between the guide rod 4 and the dehumidification box 104, and the hinge cooperation between the movable plate 106 and the connecting rod 111 and the connecting rod 112, the release film is effectively dried. This allows the movable plate 106 to move back and forth, and with the cooperation of the fixed plate 105, it can regularly squeeze the absorbent sponge 107, thereby squeezing out the water and maintaining its good water absorption effect. At the same time, during the vertical downward movement of the connecting rod 111, it can push the two sets of vertical rods 201 to move down together. At this time, the spring 202 will be stretched, and with the sliding cooperation between the guide slider and the guide groove, and the hinge cooperation between the baffle 203 and the connecting plate 2 and the connecting rod 204, the baffle 203 can be driven to move horizontally. At this time, the rectangular groove on the baffle 203 will gradually coincide with the drain outlet, thereby facilitating the discharge of the squeezed water. Conversely, when the connecting rod 111 rises, the spring 202 itself will rebound, causing the vertical rod 201 to rise automatically, thereby driving the baffle 203 to return to its original position. At this time, the rectangular groove will be offset from the drain outlet to close it, thereby preventing heat loss.

[0029] Example 2:

[0030] Based on Example 1, this embodiment is further improved in that: both the movable plate 106 and the fixed plate 105 are evenly provided with water-permeable holes, which can facilitate drainage when the water-absorbing sponge 107 is squeezed.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
