1 模具工作原理及存在问题 模压托盘模具是模压托盘生产线中的必备装置,其主要由上下模体、封边板、脱模顶杆机构等组成.热压时,上模与下模合模形成一封闭腔,将铺于下模的物料热压成型,通过上、下顶杆脱模后,完成整个模压托盘的压制过程.每次热压可同时压制两个托盘,不同结构形式的模具可压制出不同形状的托盘. 相似文献

托盘是产品在储存和运输中最基本的集装单元,在商品流通中具有广泛的工程应用.调查数据显示:目前,我国现有托盘的总数量在1亿个以上,其中木质托盘约占90%左右;同时,我国的托盘正以不低于2 000万个/a的速度递增[1].托盘质量、性能的优劣直接影响其集装产品的质量.多年来,我国木质托盘的设计应用存在设计理论方法不完善、质量检验不规范、基础技术参数较缺乏等诸多问题,常导致木质托盘设计不当,一方面大量托盘在流通过程中易损坏,直接导致产品保护包装功能的失效,产品破损;另一方面,部分生产商通过过量使用木材来提高托盘的安全性,造成木材资源的浪费.为此,结合我国实际,研究探讨木质托盘科学、合理的设计理论与方法,不仅使托盘在流通中满足承载、保护要求;同时降低托盘的生产成本,提高企业的经济效益,对于节约资源和保护环境都具有重要的工程价值. 相似文献

木塑托盘力学性能测试方法研究 总被引:3,自引:0,他引:3
在众多替代木材的托盘新技术新产品中,木塑托盘以其良好的综合性能,在发达国家的物流作业中得到广泛使用。我国目前针对通用托盘的力学性能要求和检测方法比较完善,但木塑托盘因其独特的性质,现有的通用托盘检测方法并不适用.通过试制不同规格的木塑托盘,在尝试利用现有通用托盘力学性能检测方法的基础上对木塑托盘的力学性能检测方法进行了相关的研究。 相似文献

[目的]随着物流业高速发展,托盘的应用范围迅速拓宽,其中木质托盘使用最为广泛,其大量消耗带来的问题也日益突出.对木质托盘的回收再利用进行管理一方面可以降低企业管理成本,履行企业社会责任,另一方面还可以有效节约森林资源,由此可见,构建绿色高效的木质托盘循环再利用系统十分必要且迫切,也是物流业突破发展困境,实现现代化发展的... 相似文献

A set of tools are described for optimal allocation of wood fibre at an operational planning level. These were applied to
a case study in Ireland. Allocation was based on optimising net value recovery (delivered price minus harvesting and transportation
costs) while meeting market demands and operational constraints (mainly crew capability and productivity limits). Two new
models were developed to predict harvesting costs and transportation costs for Irish forest conditions. A new model was developed
to link Sitka spruce biomass expansion factors to optimal log-making algorithms so that log and bio-energy product yields
could be estimated for individual harvest areas. An existing operational allocation model based on a tabu search heuristic
procedure was used. The case study included 16 forest harvest areas and 12 processing plants (saw logs, pallet logs, stakes,
pulp, bio-energy slash bundles, etc.). New terrestrial lidar scanning procedures were used to obtain representative stem profiles
from over 4,000 trees for the 16 forests. We demonstrated that optimal allocation of bio-energy and log products, while complex,
can be achieved through the use of appropriate management tools. 相似文献

Containerized seedlings of Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris L.) were overwintered on the ground and above ground on pallets. Soil temperatures in elevated containers were lower and showed greater fluctuation than containers on the ground. The lowest temperatures (‐15 to ‐16°C) were observed in containers stored on pallets with little or no snow cover during the winter. Temperatures in the edge rows of containers were lower than interior bed soil temperatures. Lower temperatures were also observed in the top than in the bottom of the container. The storage on pallets resulted in reduced shoot and root growth. Although insulation preventing air movements beneath the container units improved soil temperature conditions and subsequent seedling growth, the best result was obtained when seedlings were stored directly on the ground surface. 相似文献

The current study investigates with a multiple case study the relation between instrument design and policy success. The conclusion is that the instrument mix matters. The Flemish interventionist approach, which focuses more on traditional instruments, was not as effective as the Dutch stimulating approach, which uses a broad pallet of social and economic instruments, including many new environmental policy instruments. It is conspicuous that the government remains the most important regulator in all cases, although the importance of surrogate regulators is growing. Mostly the government is needed to stimulate or even create such surrogate regulators. Therefore, the government has a key position to decide which regulatory tasks will be transferred to surrogate regulators. This is currently restricted to capacity-building and certification. 相似文献
