Definitions
- the invention relates to a dry pressing method and device in the manufacturing process of a molded product, and more particularly to a method for feeding a preform into a drying area during the manufacturing process of a molded product, so that the dry pressing by a microwave drying operation is performed. Method and device.
- Plastic products made of plastic materials easily release toxins and cause serious pollution to the environment, are difficult to recycle and reuse, or are difficult to recycle and decompose, and the cost of recycling is huge, which has caused global environmental protection for many years. Serious injury. In the current era of high environmental awareness, finding non-toxic and easily recycled materials has become the mainstream in research and practical applications. At present, there have been developed products that use pulp fiber materials and / or plant fiber materials to be mixed as pulp materials. The products are made by the suction mold and the slurry is adhered to the slurry. , Generally called “molded products”. Molded products have the advantages of easy recycling, remanufacturing and reuse, and are in line with the trend of environmental protection and reuse and energy conservation and carbon reduction.
- Molded products are often visible, such as bowls, plates, and cups. Lids, packaging materials, shock-absorbing materials, cushioning materials and other products are gradually being used, and even various products have been tried to make in the form of molded products.
- the manufacturing process of a molded product is generally referred to as a "molded product manufacturing method” or a “molded product manufacturing process”. Regarding the outline of the manufacturing process of molded products, as shown in Figure 1, it must go through two operations: “suction molding” and “hot pressing and shaping”.
- suction molding is simply The slurry mold is lowered and dipped into a slurry tank full of slurry, and then a suction device vacuum sucks the slurry in the slurry tank through the suction mold, so that the mold surface of the suction mold is formed into a "blank material layer" "When the suction mold absorbs the blank layer and rises away from the head box, the blank layer gradually dehumidifies due to the continuous suction effect, and then the suction mold and the blank layer are displaced to be combined with a cold pressing mold.
- the mold squeezes the blank layer, so that the slurry layer reduces the humidity and is shaped into a "primary embryo", and then the suction mold absorbs the preliminary embryo and leaves the cold pressing mold to complete the suction molding operation.
- the "hot pressing" operation is performed by a hot pressing mold to perform the hot pressing and shaping operation on the priming product after suction molding, so that the original priming product is dried and shaped into a finished product of a molded product.
- the finished product of the molded product produced by the hot-pressing and shaping operation must still be subjected to trimming (removal of flash material), inspection (inspecting whether the quality is acceptable), and packaging (for profitability). These subsequent operations do not need to be added To repeat.
- the hot pressing of the preform is performed by hot pressing.
- the first is the wet pressing method, as shown in Figure 2.
- the hot-press shaping operation is directly performed by the hot-press shaping equipment.
- the hot-pressing temperature is 150 ° C ⁇ 10 ° C.
- the hot pressing of the embryo is a finished product of the dried molding product.
- the hot pressing time must depend on the volume of the product (the larger the product volume, the longer the hot pressing time); the second method is the dry pressing method, as shown in Figure 3.
- the original embryo is sent to a drying area for drying operation when the moisture content is about 55-70% (it can be dried by natural drying or hot air), and the moisture content is reduced to 7-10%. Then enter the hot-press shaping equipment to perform the hot-press shaping operation.
- the hot-press temperature can be the same as 150 °C ⁇ 10 °C. Because it is the hot-press shaping operation for the low-humidity preform, the hot-press time will be longer.
- the wet pressing method is shortened a lot, but the time required for drying operation (natural drying or hot air drying) is relatively required.
- the inventor is professionally engaged in the research and development and manufacturing of manufacturing equipment, manufacturing processes and finished product development of various molded products. Through the experience of contacting various equipment of molded products for a long time, I have realized the drying in the conventional dry pressing method described above. The operation (using natural drying or hot air drying) has the following defects in implementation:
- the hot air is blown across the surface of the original embryo in the hot air equipment in the drying area to reduce the humidity of the original embryo.
- the hot air can only be blown through the surface of the original embryo.
- it cannot penetrate into the interior, so there will be a gradual drying phenomenon, that is, the outer surface will be dried first, and then dried to the inside, which will make it difficult to control the drying degree of the original embryo, especially the larger original embryo.
- the dry pressing method of hot air drying will have low heating efficiency, large relative heat loss, resulting in wasted energy, and different degrees of drying, leading to the lack of product quality.
- the object of the present invention is to provide a dry pressing method and device in the manufacturing process of a molded product which has a fast drying speed, can greatly shorten the heating time, and can save a large amount of equipment space to reduce costs and increase production capacity.

- a fibrous slurry is provided from a pulp supply system area and fed to an automatic forming machine in a molding production area to suck a slurry to produce a blank layer, which is extruded into an initial embryo product;
- the conveying system carries the prototyping product into a drying zone carrying the prototyping article, the drying zone allows the conveying system to pass, and the conveying system drives the preliminary embryo to be dried in the drying zone. Drying operation is performed inside the area to reduce the initial embryo to low humidity;
- the utility model is characterized in that a microwave drying effect can be generated in the drying area, so that the passing embryos can be subjected to a microwave drying operation, and the humidity can be quickly reduced to low humidity.
- the microwave drying effect generated inside the drying area may be a continuous microwave drying effect.
- the invention also proposes a dry pressing device in the manufacturing process of a molded product.
- the structure has a pulp supply system area, which provides fibrous pulp and supplies it to an automatic forming machine in a forming production area to suck the pulp to produce a blank layer.
- a prototyping tool receives the prototyping product, and places the prototyping tool together with the prototyping product on a conveying system; the conveying system places the prototyping tool
- the original embryo is carried into a drying area, so that the original embryo is dried inside the drying area to reduce the low humidity; the original embryo passing through the drying area is sent to a hot-pressing shaping area
- the raw embryo product is subjected to hot pressing and shaping work to complete the finished product of the molded product. It is characterized in that a microwave drying device is provided inside the drying area to generate a microwave drying effect so that the passed embryo can pass through.
- the product accepts the microwave drying operation of the microwave drying equipment, and quickly reduces the humidity to low humidity.
- the microwave drying equipment provided inside the drying area may be a continuous microwave drying equipment.
- the advantages and beneficial effects of the present invention are that the dry pressing method of the microwave drying effect performed by the present invention is compared with the conventional dry pressing method of performing natural drying or hot air drying, and the advantages are as follows:
- the dry-pressing method of the present invention adopts a microwave drying device, which has a fast drying speed, can greatly shorten the heating time, and can save a large amount of equipment space to reduce costs and increase productivity.
- the dry pressing method of the present invention performs microwave drying on the original embryo, the internal and external parts of the original embryo can be heated at the same time, so the internal and external parts are dried uniformly, which can improve the quality and the pass rate of the final product.

Description
本发明是关于一种模塑产品制造过程中之干压方法及装置,尤指一种在模塑产品制造过程中将初胚品送入一烘干区,使经微波烘干作业的干压方法及装置。
以塑料材料所制成的「塑料产品」,容易释出毒素对环境产生严重污染、难以回收再利用,或回收分解难以处理、回收处理费用庞大等等问题,导致多年来已对全球环境保护产生严重伤害。在现今环保意识高涨的年代,寻找无毒、容易回收处理的材料,已成为研究及实际应用上的主流。目前已有发展以纸浆纤维材料及/或植物纤维材料混合打浆为浆质材料,由吸浆模吸浆附着浆料,再经过热压定型技术制造而成的产品,为与「塑料产品」区分,一般皆称之为「模塑产品」。模塑产品有容易回收再制造再利用的优势,符合环保再利用及节能减碳的潮流,因此快速受到工商业界及大众所接受并乐于采用,模塑产品经常可见的例如:碗、盘、杯盖、包装材、避震材、垫材等等产品都渐有采用,甚至各种产品都有尝试以模塑产品型态制造。
模塑产品的制程经过一般被总称为“模塑产品制造方法”或“模塑产品制造过程”。关于模塑产品制造过程概略区分,如图1所示,必须经过「吸浆塑型」及「热压整型」二道作业,其中,「吸浆塑型」简单来讲,是由一吸浆模下降浸入一充满浆料的浆箱内,再由一抽吸装置经由该吸浆模对浆箱内的浆料进行真空吸引,使该吸浆模的模面上型成一“胚料层”,当该吸浆模吸附该胚料层上升 离开浆箱时,因持续抽吸作用使该胚料层逐渐降湿,接着该吸浆模连同胚料层移位去与一冷压模合模挤压该胚料层,使该浆料层降低湿度并同时塑型成为一“初胚品”,然后该吸浆模吸附该初胚品离开冷压模,完成吸浆塑型的作业,接着即进行「热压整型」作业,其是由一热压模对吸浆塑型后的初胚品进行热压整型作业,使原先的初胚品干燥并定型成为模塑产品的成品。当然,经过热压整型作业产生的模塑产品的成品尚须经过切边(去除溢料)、检查(检查质量是否合格)及包装(以利出品)诸项作业,此等后续作业不必多加赘述。
目前在模塑产品制造过程中,对于初胚品的热压整型都是实行热压方式进行作业,常见的作业方式有二种,第一种为湿压法,如图2所示,其是将初胚品在含水率约55-70%状态时即以热压整型设备直接进行热压整型作业,热压温度为150℃±10℃,由直接热压将原本中高湿度的初胚品热压整型为干燥的模塑产品的成品,热压时间必须视产品的体积而定(产品体积越大热压时间必须越久);第二种方法为干压法,如图3所示,其是将初胚品在含水率约55-70%状态时先送经一烘干区进行烘干作业(可采自然干燥或采热风干燥),待含水率降低至7-10%状态时再进入热压整型设备进行热压整型作业,热压温度可同为150℃±10℃,因其是对低湿度的初胚品进行热压整型作业,所以热压时间会较湿压法缩短许多,但相对需要烘干作业(可采自然干燥或采热风干燥)的时间。
习知模塑产品制造过程中,实行干压法热压整型作业时,因可大幅减少热压整型设备的作业时间,相对即大幅减少能源耗费并可降低设备故障率,进而降低制造成本,因此模塑产品制造过程中的干压法热压整型作业已成为主流。
本发明人专业从事各种模塑产品的制造设备、制造过程及成品开发的研发及制造工作,经由长时间接触模塑产品各种设备的经验,体会到上述习知干压 法中的烘干作业(采自然干燥或采热风干燥),实施上存在着以下缺失:
1.采自然干燥的烘干作业时,必须要有占地面积足够的区域供摆置大量的初胚品,且自然干燥的时间必须足够,但自然干燥后仍经常发生干燥后的初胚品外观和质量不佳的情事;总体来讲就是,自然干燥的干压法会有占地广、费时间及容易质量不佳的缺失。
2.采热风干燥的烘干作业时,是在烘干区的热风设备中由加热的热风吹过初胚品表面,以使初胚品降湿,但因热风只能经由初胚品表面吹过,不能渗入内部,因此会产生渐层干燥的现象,亦即会由外表面先干燥,然后再往内部干燥,连带使得初胚品的干燥程度难以掌控一致,尤其越大件的初胚品,不易均匀干燥的现象就越明显;总体来讲就是,热风干燥的干压法会有加热效能低,相对热耗损大,导致浪费能源,以及干燥程度不一,导致影响产品质量的缺失。
上述问题,显然有待改进。

3.本发明的干压方法因实行微波烘干设备,热惯性极小,在该烘干区40内部不需预热时间,温度的调节和控制都比较容易,温度的任何改变都可以在几分钟内完成,无须中断生产。
4.本发明的干压方法因实行微波烘干设备,其热量是靠微波辐射转化,没有通过任何中间媒介,所以热效率高,可高达80%以上;再者,微波烘干设备本身不辐射热量,热能损失少,能达到节能减碳的效果。
5.本发明的干压方法因实行微波烘干设备,其热量是靠微波辐射转化,没有通过任何中间媒介,所以操作环境清洁,有利于环保。

本发明分为一种模塑产品制造过程中的干压方法及一种模塑产品制造过程中的干压装置,详见附下所述。
本发明所提前出的“模塑产品制造过程中的干压方法”是模塑产品制造过程中的一道步骤,因此由完整叙述一模塑产品制造过程来将干压方法揭示出。如图4所示,一种模塑产品制造过程需经过如下步骤:
1.由一供浆系统区10(例如:浆箱)提供纤维质的浆料,供给一成型生产区20内的自动成型机吸浆产生一胚料层,并经挤压后成为一初胚品31;
2.利用一仿型治具32承接该初胚品31,并将该仿型治具32连同该初胚品31放置在一输送系统33上,该放置的动作可经由人工完成或由机械手臂进行;
3.该输送系统33将该仿型治具32承载该初胚品31送入一烘干区40,该烘干区40主要是设置有一微波烘干设备,内部并容许该输送系统33通过,因此该输送系统40将该仿型治具32承载该初胚品31送入该烘干区40,自该微波烘干设备的进入口进入,并由该输送系统40带动该初胚品31在该微波烘干设备内部依序行进进行烘干作业,最终由该微波烘干设备的送出口送出,如此完成该烘干区40的作业,且此时该初胚品31已降至低湿;
4.接着将通过该烘干区40的初胚品31送进一热压整型区50,该热压整型区50主要是设置有一热压整型设备,因此将该初胚品31送进该热压整型区50 后,即进入该热压整型设备内接受热压整型作业,完成为模塑产品的成品60;5.最后将经过该热压整型区50后的模塑产品的成品60送经一切边区70,进行溢料的去除作业,再送经一检查区80,进行质量检查,最后送至一包装区90进行出品前的产品包装。
上述模塑产品制造过程的步骤中,通过该烘干区40的步骤为本发明所提出的最重要步骤,该步骤也即为本案名称「模塑产品制造过程中的干压方法」中所主张的干压方法。
接着,本发明所提出的“模塑产品制造过程中的干压装置”,该干压装置主要是在该烘干区40内部设置有一微波烘干设备,该烘干区40与该输送系统33的配合如图5所示,该烘干区40内部所设置的微波烘干设备可以是连续性的微波烘干设备,因此当该输送系统33将该仿型治具32承接该初胚品31输送进入该烘干区40内部并持续行进时,该烘干区40内部所设置的微波烘干设备实时启动,以对持续行进的初胚品31做出连续性的微波烘干作业,使该初胚品31开始降湿,直至被输送出该烘干区40时已属低湿。该烘干区40内部所设置的微波烘干设备是可以调整微波强度,且该输送系统33是可以调整行进速度,因此可视初胚品31的体积大小、表面多少,去计算所需要的空间微波量,进一步去调整该微波烘干设备的微波强度及该输送系统33的行进速度,最主要是令该初胚品31快速降湿至适当的低湿,但不是全干,以便进入后续热压整型区50的热压整型设备内时,能进行恰当的热压整型作业,使完成为质量优良的模塑产品的成品60。
