Description
Technical Field
[0001] This utility model relates to the field of composite film preparation technology, specifically a drying device for composite film preparation. Background Technology
[0002] Composite films are films formed by bonding two or more different materials together with an adhesive. They have high strength, high transparency, good mechanical properties and chemical corrosion resistance, and are therefore widely used. However, in the process of preparing and producing composite films, they usually need to be dried.
[0003] A search revealed an existing patent (publication number: CN221403785U) that discloses a drying device for composite film production. The device includes a drying chamber and a hot air blower for supplying hot air to the drying chamber. The drying chamber has an air inlet and an air outlet. The hot air blower is connected to the air inlet. The drying chamber has a feed inlet and a discharge outlet for the composite film to enter and exit the chamber. The feed inlet and discharge outlet are at the same height and located between the air inlet and the air outlet. A flow divider plate is provided between the air inlet and the feed inlet, and multiple flow divider holes are evenly distributed on the flow divider plate. The drying chamber also has a pusher assembly for promoting the flow of gas from the air inlet to the air outlet within the drying chamber. This application has the effect of improving the drying quality of composite films.
[0004] However, the above solution makes it inconvenient to tension the composite film. If wrinkles appear in the composite film during the conveying and drying process, it is difficult to dry the moisture in the wrinkles quickly. In addition, the composite film spends a short time in the drying box, which is not conducive to thoroughly drying the moisture on the surface of the composite film, resulting in inconvenience in its use.

[0007] The tensioning assembly includes: a reserved groove formed at one end of the inner wall of the housing, a threaded rod rotatably connected to the inner wall of the reserved groove, a rotating handle extending to the outside of the housing fixedly connected to one end of the threaded rod, and a threaded block threadedly connected to the surface of the threaded rod; a slide rod fixedly connected to the other end of the inner wall of the housing, a slider movably connected to the surface of the slide rod; a fixed cylinder fixedly connected to one side of the slider and the threaded block, a fixed spring fixedly connected to the inner wall of the fixed cylinder, a sliding block fixedly connected to one end of the fixed spring, a connecting seat fixedly connected to one end of the sliding block extending to the outside of the fixed cylinder, and a rotatably connected end of the connecting seat to one end of the tensioning roller.
[0008] Furthermore, the surfaces of the slider and the slide rod form a sliding structure, and one end of the slider and the threaded block are welded together with one end of the fixed cylinder.
[0009] Furthermore, a sliding structure is formed between one side of the sliding block and the interior of the fixed cylinder, and the shape of the opening inside the fixed cylinder and the sliding block is cross-shaped.
[0010] Furthermore, the mounting assembly includes: mounting slots symmetrically formed on one side of the heating box, with a fixing rod fixedly connected to the inner wall of the mounting slot; a positioning block slidably connected to the surface of the fixing rod, with a mounting spring wound around the surface of the fixing rod, and both ends of the mounting spring being fixedly connected to the bottom end of the positioning block and the inner bottom wall of the mounting slot, respectively; a mounting block fixedly connected to the top end of the positioning block; and positioning holes symmetrically formed on one side of the bottom end of the sealing plate.
[0011] Furthermore, the top of the mounting block and the interior of the positioning hole form an engaging structure, and the positioning hole and the mounting block are symmetrically distributed about the vertical central axis of the sealing plate.
[0012] Furthermore, a lever is fixedly connected to one side of the positioning block, and the lever is used to drive the two positioning blocks to slide.
[0013] Furthermore, the heating tube is serpentine in shape, and both ends of the heating tube are fixedly connected to the inner wall of the heating box by bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model rotates a handle to drive a threaded rod, causing the threaded block to slide and the fixed cylinder to slide, which in turn drives the tensioning roller to slide, thus adjusting the tension of the composite film conveyed on its surface. Simultaneously, the composite film causes the tensioning roller to slide, which in turn causes the connecting seat and sliding block to slide, compressing the fixed spring to a small compression level. Therefore, during subsequent conveying and drying of the composite film, if the composite film is too tight, it will further cause the tensioning roller to slide, compressing the fixed spring. Conversely, if the composite film is too loose, the elasticity of the fixed spring can be used to cause the connecting seat to slide, driving the tensioning roller to slide, further tightening the composite film. This ensures appropriate tension of the composite film, preventing wrinkles that could affect the subsequent drying effect. Furthermore, the use of multiple tensioning rollers and guide rollers allows the composite film to be conveyed in a Z-shaped distribution inside the chamber, extending its contact time and contact area with the heated air inside the chamber, further improving the drying rate of the composite film.
[0017] 2. This utility model uses a lever to move the mounting block down until it is completely disengaged from the positioning hole, making it easier to remove and replace the saturated activated carbon drying plate through the sealing plate. During installation, the activated carbon drying plate is inserted into the heating box, and then the elastic force of the mounting spring is used to make the mounting block lock into the positioning hole, ensuring a firm engagement between the sealing plate and one side of the heating box. This allows for quick disassembly and assembly of the sealing plate, reducing the difficulty of disassembling and replacing the activated carbon drying plate and improving its practicality.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1
[0030] like Figures 1 to 7 As shown, a drying device for preparing composite films according to the first aspect of this utility model includes a box body 1, a through groove 4 formed on one side of the box body 1, guide rollers 10 rotatably connected to the inner wall of the box body 1, and a tension roller 3 provided on one side inside the box body 1; a tensioning assembly 2 assembled inside the box body 1, which is used to realize the sliding adjustment of the tension roller 3; a door 12 fixedly connected to the front of the box body 1 by a hinge; and a heating box 5 fixedly connected to the other side of the box body 1, the top of the heating box 5 being connected to one side of the top of the box body 1 through a conduit, and the bottom of the heating box 5 being connected to... The lower end of one side of the interior of the chamber 1 is connected, and the lower end of the front of the heating chamber 5 is fixedly connected to the controller 11; the heating pipe 6 is fixedly connected to the lower end of the inner wall of the heating chamber 5, and the inner wall of the heating chamber 5 above the heating pipe 6 is fixedly connected to the circulating fan 13; a fixing groove 15 is opened at the upper end of one side of the heating chamber 5, and a sealing plate 8 is movably connected to the upper end of one side of the heating chamber 5, and activated carbon drying plates 9 extending into the interior of the heating chamber 5 are fixedly connected at equal intervals on one side of the sealing plate 8; the mounting assembly 7 is assembled on one side of the heating chamber 5, and the mounting assembly 7 is used to realize quick disassembly and assembly between the sealing plate 8 and one side of the heating chamber 5.
[0031] The tensioning assembly 2 includes: a reserved groove 202 formed at one end of the inner wall of the housing 1, a threaded rod 210 rotatably connected to the inner wall of the reserved groove 202, a handle 201 extending to the outside of the housing 1 fixedly connected to one end of the threaded rod 210, and a threaded block 205 threadedly connected to the surface of the threaded rod 210; a slide rod 204 fixedly connected to the other end of the inner wall of the housing 1, and a slider 203 movably connected to the surface of the slide rod 204; a fixed cylinder 206 fixedly connected to one side of the slider 203 and the threaded block 205, a fixed spring 207 fixedly connected to the inner wall of the fixed cylinder 206, a sliding block 208 fixedly connected to one end of the fixed spring 207, one end of the sliding block 208 extending to the outside of the fixed cylinder 206 and fixedly connected to a connecting seat 209, and one end of the connecting seat 209 rotatably connected to one end of the tensioning roller 3.
[0032] By rotating the handle 201, the threaded rod 210 is driven to rotate, causing the threaded block 205 to slide and drive the fixed cylinder 206 to slide, which in turn drives the tension roller 3 to slide, thus adjusting the tension of the composite film conveyed on its surface. At the same time, when the composite film is too tight, it will further cause the tension roller 3 to slide, thereby compressing the fixed spring 207. When the composite film is too loose, the elastic force of the fixed spring 207 can be used to make the connecting seat 209 slide, driving the tension roller 3 to slide, further tightening the composite film, thereby ensuring the appropriate tension of the composite film.
[0033] In this embodiment, a sliding structure is formed between the surfaces of the slider 203 and the slide bar 204. One end of the slider 203 and the threaded block 205 are respectively welded to one end of the fixed cylinder 206. By utilizing the sliding of the surfaces of the slider 203 and the slide bar 204, the smoothness of the sliding adjustment of the tension roller 3 is improved.
[0034] In this embodiment, a sliding structure is formed between one side of the sliding block 208 and the interior of the fixed cylinder 206. The opening inside the fixed cylinder 206 and the shape of the sliding block 208 are cross-shaped. By utilizing the sliding of the cross-shaped sliding block 208 inside the fixed cylinder 206, the smoothness of the sliding of the sliding block 208 and the connecting seat 209 is improved.
[0035] Example 2
[0036] like Figures 1 to 7 As shown, a drying apparatus for preparing composite films includes all the contents of Example 1. The mounting assembly 7 includes: a mounting groove 703 symmetrically opened on one side of the heating box 5, with a fixing rod 704 fixedly connected to the inner wall of the mounting groove 703; a positioning block 702 slidably connected to the surface of the fixing rod 704, with a mounting spring 705 wound around the surface of the fixing rod 704, and the two ends of the mounting spring 705 being fixedly connected to the bottom end of the positioning block 702 and the inner bottom wall of the mounting groove 703 respectively; a mounting block 707 fixedly connected to the top end of the positioning block 702; and positioning holes 701 symmetrically opened on one side of the bottom end of the sealing plate 8.
[0037] By pulling the lever 706, the two positioning blocks 702 slide down on the surface of the fixing rod 704 to compress the mounting spring 705, which in turn causes the mounting block 707 to slide down until it is completely disengaged from the positioning hole 701. Then, the sealing plate 8 can be pulled by the handle on the sealing plate 8, and the saturated activated carbon drying plate 9 can be taken out and replaced.
[0038] In this embodiment, the top of the mounting block 707 and the interior of the positioning hole 701 form a locking structure. The positioning hole 701 and the mounting block 707 are symmetrically distributed about the vertical central axis of the sealing plate 8. The locking between the top of the mounting block 707 and the interior of the positioning hole 701 ensures that the sealing plate 8 is firmly locked and fixed to one side of the heating box 5.
[0039] In this embodiment, a lever 706 is fixedly connected to one side of the positioning block 702. The lever 706 is used to drive the two positioning blocks 702 to slide.
[0040] In this embodiment, the heating tube 6 is serpentine in shape. Both ends of the heating tube 6 are fixedly connected to the inner wall of the heating box 5 by bolts. The serpentine heating tube 6 increases its heating area, reduces the heating dead angle, and facilitates the faster delivery of hot air into the box 1.
[0041] In this embodiment, a sealing ring 14 is fixedly connected to one side of the surface of the sealing plate 8. The area of the cross-section of the sealing ring 14 is equal to the area of the cross-section of the opening inside the fixing groove 15. The sealing ring 14 is used to improve the sealing performance after the sealing plate 8 and the fixing groove 15 are engaged.
[0042] The working principle of this practical application is as follows: First, open the door 12, then place the composite film into the box 1 through the higher slot 4, and wrap it sequentially around the guide roller 10 and the tension roller 3, so that it is conveyed out through the lower slot 4. Then, by rotating the handle 201, the threaded rod 210 is rotated. Utilizing the threaded engagement between the threaded rod 210 and the threaded block 205, the threaded block 205 slides, causing the fixed cylinder 206 to slide, which in turn drives the tension roller 3 to slide, thus adjusting the tension of the composite film conveyed on its surface. At the same time, the composite film is used to achieve tension... The tension roller 3 slides, causing the connecting seat 209 and the sliding block 208 to slide and compress the fixed spring 207 to a small compression amount. Then, during the subsequent conveying and drying of the composite film, if the composite film is too tight, it will further cause the tension roller 3 to slide, thereby compressing the fixed spring 207. If the composite film is too loose, the elasticity of the fixed spring 207 can be used to make the connecting seat 209 slide, causing the tension roller 3 to slide, thereby further tightening the composite film. This ensures that the composite film has a suitable tension and avoids wrinkles that would affect the subsequent drying effect.
[0043] Simultaneously, the circulating fan 13 and heating tube 6 are activated to deliver hot air into the chamber 1 to dry the composite film. The hot air containing moisture generated during drying can be delivered to the heating chamber 5 through a duct. The activated carbon drying plate 9 is then used to dry and adsorb the moisture in this part of the hot air. After drying, the hot air is delivered to the chamber 1 again by the circulating fan 13, realizing partial air circulation drying, reducing energy consumption and improving drying effect.
[0044] After drying, the two positioning blocks 702 can be pulled down on the surface of the fixing rod 704 by pulling the lever 706 to compress the installation spring 705, thereby causing the installation block 707 to slide down until it is completely disengaged from the positioning hole 701. Then, the sealing plate 8 can be pulled by the handle on the sealing plate 8 to remove the saturated activated carbon drying plate 9 and replace it. During installation, the lever 706 is first pulled down to make the installation block 707 slide down, and then the new activated carbon drying plate 9 is inserted into the heating box 5. The sealing ring 14 is used to improve the sealing between the sealing plate 8 and the fixing groove 15. Then, the lever 706 is released, and the elastic force of the installation spring 705 is used to make the positioning block 702 rise and drive the installation block 707 to lock into the positioning hole 701, ensuring that the sealing plate 8 is firmly locked and fixed to one side of the heating box 5.
