Description

Technical Field

[0001] The present application relates to the field of educational technology, and more specifically, to a teaching aid for papermaking experience. Background Art

[0002] With the in-depth development of the concept of quality education, the demand for historical culture and science practice education is increasing day by day. As one of the four great inventions in ancient China, papermaking has profound historical and cultural heritage and technical connotations. However, traditional teaching methods mainly rely on picture and text explanations or video demonstrations. Students often can only passively receive knowledge, lacking the opportunity to operate hands-on, and it is difficult to deeply understand and appreciate the subtlety of the papermaking process.

[0003] After retrieval, it is found that a teaching aid for papermaking experience disclosed in the prior art with the publication number CN220455993U. This teaching aid is put into the paper pulp liquid. When the materials accumulate above the filter plate, the device is taken out through a metal rod. At this time, the cover is placed above the frame, and the materials are squeezed through a pressing block. After the materials are dehydrated, wait for drying. After the paper is formed, the frame is taken out through the L-shaped pulling block and the filter plate. At this time, the paper can be taken out to complete the paper-making process. The whole process almost restores the papermaking process at that time, which is beneficial for students to experience the subtlety of the papermaking process.

[0004] Although this device can better help students experience the papermaking process, when the papermaking teaching aid is taken out from the paper pulp liquid, there is currently no special loading device to place the teaching aid for the subsequent dehydration and drying process. In this case, the water discharged from the papermaking teaching aid directly drips on the desktop, which may not only pollute the students' clothes, but also fail to effectively collect these waste waters to achieve resource recycling.

[0005] In addition, considering the limited time of regular school classes, relying on the natural air-drying method obviously cannot meet the needs of immediate teaching effects. It takes at least half an hour or even more than an hour for the paper to be initially dried and formed, which will undoubtedly have a certain impact on the course progress.

[0006] Therefore, we propose a teaching aid for papermaking experience. Utility Model Content

[0032] The forming component 2 includes a frame 21, on which a filter screen 22 is placed. The filter screen 22 is used to place the crushed pulp liquid and filter the moisture in the pulp liquid. The filter screen 22 is a papermaking net or gauze. L-shaped plates 23 are fixedly installed on both sides of the filter screen 22. The L-shaped plate 23 is convenient for taking the filter screen 22 out from the inside of the frame 21. Grooves with the same thickness as the L-shaped plate 23 are provided on both sides of the frame 21. The L-shaped plate 23 and the groove are fixed by magnetic attraction by magnets, so that the L-shaped plate 23 can be placed in the groove. Water inlet grooves 24 are provided on both sides of the frame 21 where no groove is provided. Multiple water inlet grooves 24 can be provided, but at least one water inlet groove 24 can accelerate the pulp liquid to enter the inside of the frame 21. The frame 21 is provided with an L-shaped lifting handle 25 on the same side of the water inlet groove 24. The lifting handle 25 is used to place the forming component 2 in the pulp liquid so that the pulp liquid adheres to the filter screen 22.

[0033] The supporting component 3 includes a base 31, on which a groove 32 for placing the lifting handle 25 is provided. The interior of the base 31 is hollow, and the outer wall of the frame 21 slides in contact with the inner wall of the base 31. The base 31 is used to receive the forming component 2 and collect the moisture overflowed from the pulp liquid on the filter screen 22 squeezed by the pressing block 13. A water outlet is provided on one side of the base 31, and the water outlet is sealed by a sealer 33. The water outlet and the sealer 33 are detachable and sealed. The base 31 can collect the moisture overflowed from the pulp liquid, and then pour the collected moisture back into the container containing the pulp liquid, so that the squeezed moisture can be reused, and the collected moisture will no longer spill on the desktop and dirty the students' clothes, making the entire papermaking experience process clean and hygienic.

[0034] The drying component 4 includes a motor 41 fixed to one side of the base 31. A fan blade 42 is fixed to the output end of the motor 41. The fan blade 42 is located in a cavity opened on one side wall of the base 31. The position of this cavity is higher than the position of the water outlet hole. A heater 43 is fixedly installed on the inner side of the cavity opened in the base 31. The motor 41 and the heater 43 are powered by an external power supply and are started through different control switches. Through the cooperation of the fan blade 42 and the heater 43, the wind can carry the heat energy to the inside of the base 31 to dry the pulp on the filter screen 22, accelerating the formation of the paper. A heating box 44 is sleeved outside the heater 43. The heating box 44 is fixedly installed on the inner side of the cavity opened in the base 31 and completely covers the cavity. Three heat dissipation pipes 45 are communicated with the outside of the heating box 44. At least one heat dissipation pipe 45 is provided. Heat dissipation holes 46 arranged linearly are provided at the bottom of the heat dissipation pipe 45. The heat dissipation holes 46 are used to discharge the heat driven by the fan blade 42 to various positions inside the base 31, making the pulp evenly heated and improving the speed of paper formation. A water separation plate 47 is fixedly installed inside the base 31. The water separation plate 47 is located below the heat dissipation holes 46 and is arranged in an inclined shape. One end of the water separation plate 47 close to the heating box 44 is higher than the other end, and a groove convenient for sealing and fixing with the heating box 44 is opened at the end of the water separation plate 47 close to the heating box 44. An opening is provided on one side of the water separation plate 47 close to the water outlet hole, facilitating the water squeezed out from the pulp liquid to flow to the bottom of the base 31. Another function of the water separation plate 47 is to prevent the hot air generated by the cooperation of the fan blade 42 and the heater 43 from heating the squeezed-out water to form too much water vapor. By blocking with the water separation plate 47, the generation of water vapor can be reduced, preventing the water vapor from affecting the speed of paper formation.

[0035] Working principle: When in use, first hold the lifting handle 25, put the frame 21 and the filter screen 22 into a container containing pulp liquid, so that the pulp liquid adheres to the filter screen 22, and then take out the frame 21 and place it above the base 31, so that the water inside the pulp liquid flows into the inside of the base 31. Then place the cover plate 12 above the filter screen 22, and squeeze the pulp liquid on the filter screen 22 through the pressing block 13 to squeeze out the water inside the pulp liquid, making the paper form faster. In order to further improve the speed of paper formation, start the motor 41 and the heater 43. The motor 41 drives the fan blade 42 to rotate, and the generated wind blows to the heater 43, dispersing the heat generated by the heater 43 to each heat dissipation pipe 45 through the heating box 44, and discharging the heat through the heat dissipation holes 46 opened on the heat dissipation pipe 45 to dry the pulp on the filter screen 22 and improve the speed of paper formation.
