Description
本創作係關於一種模塑產品製造過程中之乾壓裝置,尤指一種在模塑產品製造過程中將初胚品送入一烘乾區,使經微波烘乾作業之乾壓裝置。The present invention relates to a dry pressing device in a manufacturing process of a molded product, and more particularly to a dry pressing device for feeding an initial blank into a drying zone in a manufacturing process of a molded product to perform a microwave drying operation.
按,以塑膠材料所製成之「塑膠產品」,有容易釋出毒素對環境產生嚴重汙染、難以回收再利用,或回收分解難以處理、回收處理費用龐大等---等問題,導致多年來已對全球環境保護產生嚴重傷害。在現今環保意識高漲之年代,尋找無毒、容易回收處理之材料,已成為研究及實際應用上之主流。目前已有發展以紙漿纖維材料及/或植物纖維材料混合打漿為漿質材料,藉由吸漿模吸漿附著漿料,再經過熱壓定型技術製造而成之產品,為與「塑膠產品」區分,一般皆稱之為「模塑產品」。模塑產品有容易回收再製造再利用之優勢,符合環保再利用及節能減碳之潮流,因此快速受到工商業界及普羅大眾所接受並樂於採用,模塑產品經常可見的例如:碗、盤、杯蓋、包裝材、避震材、墊材等---等產品都漸有採用,甚至各種產品都有嘗試以模塑產品型態製造。According to the "plastic products" made of plastic materials, it is easy to release toxins that cause serious pollution to the environment, difficult to recycle and reuse, or difficult to recycle and recycle, and the cost of recycling is so large, etc. It has caused serious harm to global environmental protection. In today's era of high environmental awareness, the search for non-toxic, easy-to-recycle materials has become the mainstream of research and practical applications. At present, it has been developed to use a pulp fiber material and/or a plant fiber material as a slurry material, and the slurry is adhered by a suction mold, and then the product is manufactured by hot pressing and setting technology, and is a "plastic product". The distinction is generally referred to as "molded products." Molded products have the advantages of easy recycling, re-manufacture and reuse, and are in line with the trend of environmental protection and energy conservation and carbon reduction. Therefore, they are quickly accepted by the business community and the general public, and molded products are often seen, for example, bowls, plates, Cup lids, packaging materials, shock absorbers, mats, etc. - and other products are gradually adopted, and even various products have tried to manufacture in the form of molded products.
模塑產品之製程經過一般被總稱為"模塑產品製造方法"或"模塑產品製造過程"。關於模塑產品製造過程概略區分,如圖1所示,必須經過「吸漿塑型」及「熱壓整型」二道作業,其中,「吸漿塑型」簡單來講,係由一吸漿模下降浸入一充滿漿料之漿箱內,再由一抽吸裝置經由該吸漿模對漿箱內之漿料進行真空吸引,使該吸漿模之模面上型成一"胚料層",當該吸漿模吸附該胚料層上昇離開漿箱時,因持續抽吸作用使該胚料層逐漸降濕,接著該吸漿模連同胚料層移位去與一冷壓模合模擠壓該胚料層,使該漿料層降低濕度並同時塑型成為一"初胚品",然後該吸漿模吸附該初胚品離開冷壓模,完成吸漿塑型之作業,接著即進行「熱壓整型」作業,其係藉由一熱壓模對吸漿塑型後之初胚品進行熱壓整型作業,使原先之初胚品乾燥並定型成為模塑產品之成品。當然,經過熱壓整型作業產生之模塑產品之成品尚須經過切邊(去除溢料)、檢查(檢查品質是否合格)及包裝(以利出品)諸項作業,惟此等後續作業不必多加贅述。The process of molding a product is generally referred to collectively as a "molding product manufacturing method" or a "molding product manufacturing process." Regarding the outline of the manufacturing process of molded products, as shown in Figure 1, it is necessary to go through the two processes of "slurry molding" and "hot pressing". Among them, "absorbent molding" is simply a suction. The slurry mold is immersed in a slurry tank filled with the slurry, and then the suction slurry is vacuum-applied to the slurry in the slurry tank by a suction device, so that the mold surface of the suction mold is shaped into a "male layer". "When the suction mold adsorbs the billet layer and rises away from the pulp box, the billet layer is gradually dehumidified by continuous suction, and then the suction mold is displaced along with the billet layer to form a cold press mold. The mold layer is pressed to reduce the humidity and simultaneously shape into a "primary product", and then the suction mold absorbs the original embryo and leaves the cold pressing mold to complete the operation of the suction molding. Then, the "hot pressing" operation is carried out by hot pressing the original preform after the suction molding by a hot pressing die, so that the original original product is dried and shaped into a molded product. Finished product. Of course, the finished products of the molded products produced by the hot-pressing work must be subjected to trimming (removing flash), inspection (checking the quality of the products), and packaging (for the production), but these subsequent operations are not necessary. More details.
目前在模塑產品製造過程中,對於初胚品之熱壓整型都是採行熱壓方式進行作業,常見之作業方式有二種,第一種為濕壓法,如圖2所示,其係將初胚品在含水率約55-70%狀態時即以熱壓整型設備直接進行熱壓整型作業,熱壓溫度為150℃±10℃,藉由直接熱壓將原本中高濕度的初胚品熱壓整型為乾燥之模塑產品之成品,熱壓時間必須視產品的體積而定﹙產品體積越大熱壓時間必須越久﹚;第二種方法為乾壓法,如圖3所示,其係將初胚品在含水率約55-70%狀態時先送經一烘乾區進行烘乾作業(可採自然乾燥或採熱風乾燥),待含水率降低至7-10%狀態時再進入熱壓整型設備進行熱壓整型作業,熱壓溫度可同為150℃±10℃,因其係對低濕度的初胚品進行熱壓整型作業,所以熱壓時間會較濕壓法縮短許多,但相對需要烘乾作業(可採自然乾燥或採熱風乾燥)的時間。At present, in the manufacturing process of molded products, the hot pressing type of the initial embryo is carried out by hot pressing, and there are two common working methods. The first one is wet pressing, as shown in Fig. 2. When the initial product is in the state of moisture content of about 55-70%, the hot pressing type is directly subjected to hot pressing, and the hot pressing temperature is 150 ° C ± 10 ° C, and the original medium and high humidity is directly hot pressed. The hot stamping of the initial embryo is the finished product of the dried molded product, and the hot pressing time must be determined according to the volume of the product (the larger the volume of the product, the longer the hot pressing time must be); the second method is the dry pressing method, as shown in the figure As shown in Fig. 3, when the initial product is in the state of moisture content of about 55-70%, it is first sent to a drying zone for drying operation (can be naturally dried or heated to dry), and the moisture content is reduced to 7-10. In the % state, the hot pressing type equipment is further subjected to the hot pressing type operation, and the hot pressing temperature can be 150 ° C ± 10 ° C, because it is hot pressing and shaping work for the low humidity initial embryo product, so the hot pressing time It will be much shorter than the wet pressing method, but it will take time to dry (can be naturally dried or heated to dry).
習知模塑產品製造過程中,採行乾壓法熱壓整型作業時,因可大幅減少熱壓整型設備的作業時間,相對即大幅減少能源耗費並可降低設備故障率,進而降低製造成本,因此模塑產品製造過程中之乾壓法熱壓整型作業已成為主流。In the manufacturing process of the conventional molded product, when the dry pressing method is used, the operation time of the hot pressing and finishing equipment can be greatly reduced, and the energy consumption and the equipment failure rate can be reduced, thereby reducing the manufacturing cost. Therefore, dry pressing hot pressing work in the manufacturing process of molded products has become the mainstream.
本創作人專業從事各種模塑產品之製造設備、製造過程及成品開發之研發及製造工作,經由長時間接觸模塑產品各種設備之經驗,體認到上述習知乾壓法中之烘乾作業(採自然乾燥或採熱風乾燥),實施上存在著以下缺失:The creator specializes in the R&D and manufacturing of manufacturing equipment, manufacturing processes and finished product development of various molded products. Through the experience of long-term contact with various equipments of molded products, the drying operation in the above-mentioned conventional dry pressing method is recognized. Naturally dry or hot air drying), there are the following defects in implementation:
1. 採自然乾燥之烘乾作業時,必須要有佔地面積足夠之區域供擺置大量之初胚品,且自然乾燥之時間必須足夠,但自然乾燥後仍經常發生乾燥後的初胚品外觀和品質不佳之情事;總體來講就是,自然乾燥之乾壓法會有佔地廣、費時間及容易品質不佳之缺失。1. When drying in natural drying, it is necessary to have a sufficient area for placing a large number of original embryos, and the time for natural drying must be sufficient, but the dried embryos often occur after drying naturally. The appearance and quality of the situation is not good; in general, the dry method of natural drying will have a wide footprint, time and easy quality.
2. 採熱風乾燥之烘乾作業時,係在烘乾區之熱風設備中藉由加熱之熱風吹過初胚品表面,以使初胚品降濕,惟因熱風只能經由初胚品表面吹過,不能滲入內部,因此會產生漸層乾燥之現象,亦即會由外表面先乾燥,然後再往內部乾燥,連帶使得初胚品之乾燥程度難以掌控一致,尤其越大件之初胚品,不易均勻乾燥之現象就越明顯;總體來講就是,熱風乾燥之乾壓法會有加熱效能低,相對熱耗損大,導致浪費能源,以及乾燥程度不一,導致影響產品品質之缺失。2. In the drying operation of hot air drying, the hot air of the drying zone is blown through the surface of the original embryo by heated hot air to dehumidify the initial embryo, but the hot air can only pass through the surface of the original embryo. Blowing, can not penetrate into the interior, so it will produce the phenomenon of gradual drying, that is, the outer surface will be dried first, and then dried to the inside, so that the dryness of the initial embryo is difficult to control, especially the larger embryo The phenomenon that the product is not easy to be uniformly dried is more obvious; in general, the dry pressing method of hot air drying has low heating efficiency, large relative heat loss, waste of energy, and different degrees of drying, which may affect the lack of product quality.

本創作所說明之"模塑產品製造過程中之乾壓方法"係模塑產品製造過程中的一道步驟,因此由完整敘述一模塑產品製造過程來將乾壓方法揭示出。如圖4所示,一種模塑產品製造過程乃經過如下步驟: 1.由一供漿系統區10(例如:漿箱)提供纖維質之漿料,供給一成型生產區20內的自動成型機吸漿產生一胚料層,並經擠壓後成為一初胚品31; 2. 利用一仿型治具32承接該初胚品31,並將該仿型治具32連同該初胚品31放置在一輸送系統33上,該放置之動作可經由人工完成或藉由機械手臂進行; 3. 該輸送系統33將該仿型治具32承載該初胚品31送入一烘乾區40,該烘乾區40主要是設置有一微波烘乾設備,內部並容許該輸送系統33通過,因此該輸送系統40將該仿型治具32承載該初胚品31送入該烘乾區40,即係自該微波烘乾設備之進入口進入,並即由該輸送系統40帶動該初胚品31在該微波烘乾設備內部依序行進進行烘乾作業,最終由該微波烘乾設備之送出口送出,如此完成該烘乾區40之作業,且此時該初胚品31已降至低濕; 4. 接著將通過該烘乾區40之初胚品31送進一熱壓整型區50,該熱壓整型區50主要是設置有一熱壓整型設備,因此將該初胚品31送進該熱壓整型區50後,即進入該熱壓整型設備內接受熱壓整型作業,完成為模塑產品之成品60; 5. 最後將經過該熱壓整型區50後之模塑產品之成品60送經一切邊區70,進行溢料之去除作業,再送經一檢查區80,進行品質檢查,最後送至一包裝區90進行出品前之產品包裝。The "dry pressing method in the manufacturing process of a molded product" described in the present invention is a step in the manufacturing process of a molded product, and thus the dry pressing method is revealed by a complete description of a molding product manufacturing process. As shown in Fig. 4, a molding product manufacturing process is carried out as follows: 1. A fibrous slurry is supplied from a slurry supply system zone 10 (e.g., a pulp tank) to an automatic molding machine in a molding production zone 20. The billet produces a layer of the billet and is extruded to form an initial blank 31; 2. the profiling piece 31 is taken up by a profiling fixture 32, and the profiling fixture 32 is combined with the original preform 31. Placed on a transport system 33, the action of the placement can be done manually or by a robotic arm; 3. The transport system 33 carries the profiling tool 32 to carry the priming product 31 into a drying zone 40, The drying zone 40 is mainly provided with a microwave drying device, and allows the conveying system 33 to pass through, so that the conveying system 40 carries the original jig 32 to the drying zone 40, that is, And entering from the inlet of the microwave drying device, and the conveying system 40 drives the priming product 31 to sequentially perform drying operation inside the microwave drying device, and finally the outlet of the microwave drying device Delivered, thus completing the operation of the drying zone 40, and at this time the primed product 31 has been lowered to low humidity 4. The raw preform 31 passing through the drying zone 40 is then fed into a hot-pressing zone 50, and the hot-pressing zone 50 is mainly provided with a hot pressing type device, so that the initial blank 31 is sent After entering the hot-pressing zone 50, the hot-pressing type device is subjected to the hot-pressing operation to complete the finished product 60 of the molded product; 5. Finally, the mold after passing through the hot-pressing zone 50 The finished product 60 of the plastic product is sent through all the side areas 70 for the removal of the flash material, and then sent to an inspection area 80 for quality inspection, and finally sent to a packaging area 90 for product packaging before the production.

"."
接著,說明本創作所訴求之"模塑產品製造過程中之乾壓裝置",該乾壓裝置主要是在該烘乾區40內部設置有一微波烘乾設備,該烘乾區40與該輸送系統33之配合如圖5所示,該烘乾區40內部所設置之微波烘乾設備可以是連續性之微波烘乾設備,因此當該輸送系統33將該仿型治具32承接該初胚品31輸送進入該烘乾區40內部並持續行進時,該烘乾區40內部所設置之微波烘乾設備即時啟動,以對持續行進之初胚品31做出連續性之微波烘乾作業,使該初胚品31開始降濕,直至被輸送出該烘乾區40時已屬低濕。該烘乾區40內部所設置之微波烘乾設備是可以調整微波強度,且該輸送系統33是可以調整行進速度,因此可視初胚品31之體積大小、表面多寡,去計算所需要之空間微波量,進一步去調整該微波烘乾設備的微波強度及該輸送系統33的行進速度,最主要是令該初胚品31快速降濕至適當的低濕,但不是全乾,以便進入後續熱壓整型區50之熱壓整型設備內時,能進行恰當的熱壓整型作業,使完成為品質優良的模塑產品之成品60。Next, the "dry pressing device in the manufacturing process of the molded product" claimed by the present invention is described. The dry pressing device is mainly provided with a microwave drying device inside the drying zone 40, the drying zone 40 and the conveying system. As shown in FIG. 5, the microwave drying device disposed inside the drying zone 40 may be a continuous microwave drying device, so when the conveying system 33 carries the dummy fixture 32 to the original embryo product When the container 31 is transported into the interior of the drying zone 40 and continues to travel, the microwave drying device disposed inside the drying zone 40 is immediately activated to make a continuous microwave drying operation for the continuous propagation of the original blank 31. The primed product 31 begins to dehumidify until it is transported out of the drying zone 40 to be low humidity. The microwave drying device disposed inside the drying zone 40 can adjust the microwave intensity, and the conveying system 33 can adjust the traveling speed. Therefore, the volume of the initial blank 31 and the surface can be used to calculate the required space microwave. To further adjust the microwave intensity of the microwave drying apparatus and the traveling speed of the conveying system 33, the most important thing is to quickly dehumidify the original blank 31 to a suitable low humidity, but not to dry completely, so as to enter the subsequent hot pressing. In the hot-pressing type of the in-line area 50, an appropriate hot-pressing operation can be performed to complete the finished product 60 of a high-quality molded product.
