Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, and in particular to a drying device for composite paper production. Background Technology

[0002] In the composite paper production process, the drying equipment used to remove residual moisture after laminating multiple layers of substrates and to cure the composite adhesive is a key piece of equipment that determines the quality and production efficiency of the finished composite paper. It uses a controllable heating method to ensure that the composite paper reaches the preset dryness during stable conveying, thus ensuring the bonding strength between the multiple substrates and preventing problems such as wrinkling and deformation of the paper due to overheating or uneven drying.

[0003] A search revealed Chinese patent publication number CN218764398U, which discloses a drying device for composite paper production, relating to the field of composite paper production. The device includes a drying oven with a box body connected to both the front and back. An electric heating tube is vertically fixed to the inner side of the box body's inner cavity. A partition is vertically fixed to the inner cavity of the box body, and a support is fixedly fixed to the outer side of the partition. A blower is fixedly fixed to the outer side of the support, with the blower's outlet extending through the inner side of the partition. A shell is fixedly connected to the top and bottom of the drying oven. This utility model provides a drying device for composite paper production. During drying, the electric heating tube heats the material inside the box. Simultaneously, the blower starts operating, transferring heat from the box body to the drying oven to dry the material. At the same time, a first motor drives a screw to rotate via a bearing seat. The screw rotation causes a threaded block to reciprocate left and right, and the threaded block causes a sliding sleeve to slide on a sliding rod.

[0004] The aforementioned patent specification mentions that "simultaneously, the first motor drives the screw to start rotating through the bearing seat, the screw rotation drives the threaded block to reciprocate left and right, and the threaded block drives the sliding sleeve to slide on the sliding rod." The above content can increase the drying effect of the material in the drying oven, but the hot air distribution of some drying devices is unbalanced, the air outlet layout in the drying oven is unreasonable, the composite paper near the air outlet is heated too much, while the area far from the air outlet is not covered by hot air enough, resulting in obvious differences in the dryness of different areas of the paper. Therefore, a drying device for composite paper production is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for composite paper production, which solves the problem of uneven heating in some drying devices.

[0006] To achieve the above objectives, this utility model provides a drying device for composite paper production, comprising a protective shell, two flat rollers rotatably connected inside the protective shell, a conveyor belt inside the protective shell, a heating roller rotatably connected outside the conveyor belt, uniform heating mechanisms on both sides of the outer side of the protective shell, and two dust removal mechanisms at the bottom of the outer side of the protective shell. Each uniform heating mechanism includes two fans, which are fixedly connected to both sides of the outer side of the protective shell. A connecting pipe is fixedly connected to the input end of each fan, and a filter block is slidably connected inside the connecting pipe. A coarse filter layer is fixedly connected inside the filter block, a medium filter layer is fixedly connected outside the coarse filter layer, and a fine filter layer is fixedly connected outside the medium filter layer. A quick-release assembly is provided outside the filter block, and two air outlets are fixedly connected to the output end of each fan.

[0007] The dust removal mechanism includes a housing, which is fixedly connected to the outside of a protective shell, and two fans are fixedly connected to the outside of the housing.

[0008] The outer ends of the heating drum are rotatably connected to the inside of the protective shell, the outer side of the middle filter layer is fixedly connected to the inside of the filter block, and the outer side of the fine filter layer is fixedly connected to the inside of the filter block.

[0009] The quick-release assembly includes a second connecting plate, which is fixedly connected to the outside of the filter block and slidably connected to the inside of the connecting tube.

[0010] The bottom of the connecting plate two is fixedly connected to two fixing posts, and the bottom of the fixing posts is slidably connected to the top of the protective shell.

[0011] The connecting plate 2 is slidably connected to the top of the protective shell, and the connecting pipe is fixedly connected to the outside of the protective shell.

[0012] The protective shell has two filter plates that slide inside, and a connecting plate that is fixedly connected to the outside of the filter plates.

[0013] The outer side of the connecting plate is slidably connected to the inside of the protective shell, and a handle is provided on the outer side of the connecting plate.

[0014] 1. This utility model discloses a drying device for composite paper production. It uses a fan to drive outside air into the filter block through a connecting pipe. After passing through three stages of filtration—coarse filter layer, medium filter layer, and fine filter layer—clean air is blown vertically onto the composite paper from the air outlet. This achieves the function of uniformly blowing clean hot air onto the composite paper, ensuring uniform heating, preventing local over-drying or under-drying, reducing delamination and embrittlement problems caused by uneven drying, and comprehensively improving drying quality and production efficiency.

[0015] 2. The present invention relates to a drying device for composite paper production. By rotating a fan, the air inside the protective shell is circulated to create negative pressure, which draws residual dust and impurities into the shell and filters them through a filter plate. The filter plate can be quickly removed and replaced via a connecting plate, effectively intercepting dust and impurities and preventing them from adhering to the composite paper and affecting product quality. The continuous dust removal capability reduces the scrap rate of composite paper caused by dust pollution, ensuring product quality stability and improving production continuity.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] The first embodiment of this application is as follows: Please see Figure 1 , Figure 3 and Figure 4 A drying device for composite paper production includes a protective shell 1. Two smoothing rollers 2 are rotatably connected inside the protective shell 1. The smoothing rollers 2 have smooth surfaces and are arranged parallel to each other. By rotating, they apply uniform pressure to the incoming composite paper, smoothing out surface wrinkles and curls, ensuring uniform contact between the composite paper and the heating components during subsequent drying, and avoiding localized drying differences caused by irregular shapes. A conveyor belt 6 is installed inside the protective shell 1, and a heating roller 5 is rotatably connected to the outside of the conveyor belt 6. The conveyor belt 6, driven by a motor, continuously and stably transports the composite paper. Its conveying speed matches the rotation speed of the heating roller 5, ensuring consistent residence time of the composite paper in the drying area and ensuring uniform drying effect. Heat is transferred through rolling contact with the surface of the composite paper to initially heat and evaporate moisture or organic solvents in the adhesive layer of the composite paper, achieving initial curing. Uniform heating mechanism 4 is provided on both sides of the outer side of the protective shell 1. Uniform heating mechanism 4 is used to blow clean hot air onto the surface of the composite paper to compensate for the limitations of contact heating by the heating roller 5 and achieve uniform heating of the entire composite paper. Two dust removal mechanism 3 is provided on the bottom of the outer side of the protective shell 1. Dust removal mechanism 3 is used to continuously remove dust and impurities inside the protective shell 1 to prevent them from adhering to the composite paper and affecting product quality. The protective shell 1 is used to form a relatively sealed drying space to reduce heat loss and improve thermal efficiency, while isolating external dust and impurities and providing installation support for internal components. The uniform heating mechanism 4 includes two fans 41, which are externally fixedly connected to the outer sides of the protective shell 1. A connecting pipe 42 is fixedly connected to the input end of each fan 41. The fans 41 draw in and pressurize outside air to provide power for hot air delivery, ensuring sufficient airflow to the surface of the composite paper. A filter block 43 is slidably connected inside the connecting pipe 42. The connecting pipe 42 guides outside air into the filter block 43 and provides a sliding mounting track for the filter block 43 to ensure stable connection. A coarse filter layer 44 is fixedly connected inside the filter block 43. The filter block 43 provides an integrated mounting carrier for the coarse filter layer 44, the medium filter layer 45, and the fine filter layer 46, forming an integrated filter unit for easy disassembly and maintenance. A medium filter layer 45 is fixedly connected to the outside of the coarse filter layer 44. The medium filter layer 45 uses medium-pore size filter media such as fiberglass wool to further filter fine dust, pollen, and other medium-sized particles in the air. To remove large particles and improve air cleanliness, the coarse filter layer 44 uses a large-pore filter screen, such as stainless steel mesh, to mainly intercept large particles of impurities in the air, such as dust clumps and fiber lint, preventing them from entering the device and contaminating the composite paper. The fine filter layer 46 is fixedly connected to the outside of the middle filter layer 45. The filter block 43 is equipped with a quick-release assembly 48, which is used to quickly remove and install the filter block 43. The filter layer can be replaced without tools, improving maintenance efficiency. The output end of the blower 41 is fixedly connected to two air outlets 47. The air outlets 47 adopt a flat air outlet design, so that clean hot air is blown vertically and evenly onto the surface of the composite paper, covering the area not directly contacted by the heating roller 5, eliminating local temperature differences. The two ends of the heating roller 5 are rotatably connected to the inside of the protective shell 1. The outside of the middle filter layer 45 is fixedly connected to the inside of the filter block 43, and the outside of the fine filter layer 46 is fixedly connected to the inside of the filter block 43. The quick-release assembly 48 includes a second connecting plate 481. The second connecting plate 481 is externally fixedly connected to the outside of the filter block 43. The second connecting plate 481 is externally slidably connected to the inside of the connecting tube 42. Two fixing posts 482 are fixedly connected to the bottom of the second connecting plate 481. The bottom of the fixing posts 482 is slidably connected to the top of the protective shell 1. The fixing posts 482 are inserted into the corresponding holes at the top of the protective shell 1 to position and fix the filter block 43, preventing it from shifting due to airflow impact when the fan 41 is working. The second connecting plate 481 is externally slidably connected to the top of the protective shell 1. The second connecting plate 481 connects the filter block 43 and the fixing posts 482, providing a force point for the pull-out of the filter block 43, while limiting the sliding direction of the filter block 43 in the connecting tube 42. The connecting tube 42 is externally fixedly connected to the outside of the protective shell 1.

[0025] like Figure 2 and Figure 5As shown, the dust removal mechanism 3 includes a housing 31, which is fixedly connected to the outside of the protective housing 1. Two fans 32 are fixedly connected to the outside of the housing 31. The fans 32 generate negative pressure inside the housing 31 by rotating at high speed, drawing dust-laden air from inside the protective housing 1 into the housing 31 to provide power for dust removal. The housing 31 is used to house the filter plates 33 and guide the flow of dust-laden air to prevent dust leakage. Two filter plates 33 are slidably connected inside the protective housing 1. A connecting plate 34 is fixedly connected to the outside of the filter plates 33. The filter plates 33 use adsorbent filter materials such as activated carbon filters to intercept dust and impurities drawn into the housing 31 and purify the air. The connecting plate 34 is slidably connected to the inside of the protective housing 1 and has a handle on its outside.

[0026] Working principle: The composite paper to be dried is fed into the equipment between two flat rollers 2. The motor inside the protective shell 1 drives the flat rollers 2 to rotate, pushing the composite paper forward. Then the composite paper is conveyed to the conveyor belt 6. The motor inside the protective shell 1 synchronously drives the conveyor belt 6 to rotate, conveying the composite paper forward. It cooperates with the heating roller 5 rotating above the conveyor belt 6 to perform preliminary drying of the composite paper.

[0027] During this process, the uniform heating mechanism 4 works in concert. The fans 41 on both sides draw in outside air, which is then filtered through three stages—coarse filter layer 44, medium filter layer 45, and fine filter layer 46—within the filter block 43 to obtain clean air. The clean air is then blown out from the air outlet 47 by the fans 41, which blows vertically toward the composite paper to ensure uniform heating. If the filter layer needs to be replaced, it can be done through the quick-release assembly 48. Simply pull out the connecting plate 481 to remove the filter block 43 from the connecting pipe 42. During installation, slide the filter block 43 into the connecting pipe 42 and simultaneously insert the fixing post 482 into the corresponding hole at the top of the protective shell 1. The composite paper, after being blown by the air outlet 47, continues to move forward under the drive of the conveyor belt 6, and then undergoes secondary drying through another heating roller 5. Finally, it is flattened again by another set of flattening rollers 2 before being output.

[0028] During the drying process, the dust removal mechanisms 3 on both sides of the bottom of the device work simultaneously to prevent dust from affecting the quality of the composite paper. The fan 32 on the outer shell 31 rotates and sucks the dust and impurities remaining inside the protective shell 1 into the outer shell 31 through negative pressure, and is intercepted by the filter plate 33. The filter plate 33 can be removed and replaced through the connecting plate 34 to ensure that the drying space is always clean and to prevent the composite paper from being contaminated.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
