M3120 德式T型门封边机

型号/ Model：M3120

应用/Application

主要用于现代极简风格家居薄边柜体、隐形门、子母门、开放格的一些工艺应用。

This model is mainly applied to thin-edged cabinets with minimalist design, invisible doors, unequal double doors, open cabinets, German T-shaped doors, and other furniture requiring PUR edge banding.

机身结构

Machine structure

采用Q235钢板焊接机身，并在机身内部四周用100×100方通，进行框架式加固，使机身强度更高，方通采用热锌材质，加强机身的同时，它也一个储气罐，贯穿总个机身，给整机提供更加稳定的气源供应从而提高设备运行的稳定性，由于本机为隐形门专用设备，封边形状为垂直角L形而且比较厚所以要求机身每个部件总成安装必须是垂直和水平，为此机身平台和导轨面采用龙门铣进行平面加工，在加工前已对机身进行退火消除应力处理，防止在使用过程中变形，影响设备性能和延长使用寿命。

The machine body is welded with Q235 steel plate and all four sides of the its inner are equipped with 100x100 square tubes to reinforce the performance of the model. The square tubes which are made of hot zinc material, also serve as an air storage tank to provide sustainable air flow. As the model is specially designed for invisible doors which require the edge banding to be L-shaped and thick enough, every part of the machine has to be installed vertically and horizontally. The machine body and guide rail surface are plane-processed with Plano-milling machine. The machine body has been annealed to avoid deformation through operation, to improve performance and to extend its service life.

压梁结构   

Pressing beam unit

由于门扇为较大较厚工件，压好每一件板平稳的走过就显得至关重要，所以本机型采用了焊接，退火，精加工的钢制压梁结构，自身的厚重力牢牢的压住板件输送到每个加工单元进行精准加工，与钢梁配套的履带和板件接触，避免传统滚轮方式对工件表面形成的摩擦痕迹出现。

As the door is large and thick, it’s of great importance to keep every board pressed firmly during the operation process. So this model is equipped with a steel-made pressing beam structure which has been welded, annealed and fine-processed. the structure is strong enough to make sure that every board can be pressed firmly during transportation   to separate unit to be processed. The steel-supported crawler-type structure gets in touch with the board to make sure its surface won’t get friction which is common with traditional roller method.

进料结构

Feeding structure

进料部分的结构设计，对于一台长期加工厚重工件封边机来说也是非常重要的，它决定了工件在整个运行过程中的直线度，不管是自动线还是人工阶入放板，厚重的工件推入时对进料靠板都是有一定的撞击力，长此以往就会导致歪斜，出现跑板现象，为防止或减少这一问题出现，本结构采用了模具浇铸的铸铁支撑座，它具有良好的抗变形优点，确保在长期使用过程中的稳定性。

The structure design for the feeding part is very important for an edge banding machine which needs to process thick and heavy boards on a regular basis. It decides whether the board can move in straight direction or not. Be it automatic or manual, there is impact force on the feeding plate when the heavy board is fed on. The force may in the long run may get the board derailed. To solve this problem, the feeding structure is equipped with base made of cast iron which prevents the deformation of the feeding plate and provides stability.

带伺服控制预铣单元

Servo-controlled pre-milling unit

铣形单元采用两组，铣形方式（配备4把金刚石刀具）对异形封边面进行铣形加工，每组均采用正反转跳刀方式，可以确保前后分部面不蹦边，并且两组铣形单元还配备了同步升降机构，利用伺服电机对铣刀进行范围内上下移动来实现隐形门台阶高低调整，改变如图A和C之间比例分配。

There are two sets of milling units. With four diamond knives, the unit gets the shaped face milled. Each set adopts forward and backward knife jumping method to make sure the front and rear edges are smooth. Besides, the unit is also equipped with synchronous lifting mechanism with servo control to adjust the step height of the invisible door, namely the ratio of A and C in the left picture.

PUR涂胶单元（伺服调胶）

PUR gluing unit (with servo control)

涂胶装置是根据技术要求需要自行设计开发，采用伺服电机通过操作界面数字化调整胶量，无需人工机械调节，并在每加工一件板伺服电机会翻动胶闸再回到胶量设定厚度位置，防止杂物阻挡胶量，由于门扇较厚，涂胶用量比较大，防止PUR即时供胶不足，涂胶装置特意设计了内部约300克储胶量，保证了连续封边充足的胶量供应，也没有过大的胶量沉积在胶盒内难以清理问题，PUR在超过一定时间不使用是需要清理干净防止固化损坏装置，我们设计有一键排胶功能，送带平台可通过功能键自动向右侧移留出排胶空间，方便放置容器，再按下排胶按钮快速完成清理。

The gluing device is designed according to the technical requirements. With servo motor, the glue amount can be adjusted automatically through entering specific number on the operation interface. When a board is processed, the servo motor will turn the rubber brake to the set position of the glue amount, preventing sundries from entering the glue unit. As the thick door requires for a large amount of glue, the device is designed to store 300g glue to ensure sufficient supply of PUR glue. When the PUR glue is not used for a while, it needs to be cleaned to protect the device from damage caused by glue solidification. In this regard, we have designed one-key glue discharge function. The belt feeding platform can move, through the function key, to the right to leave space for glue discharge container, and then the cleaning job can be done through pressing the discharge button.

带伺服控制的组合压贴单元  

Combined pressing unit with servo control

铣好形的板件和涂好胶的边带到达主压轮位置进行会合，首先在A位置粘合，烤灯稍加软化后快速进行预压导向板完成A、B直角B、C定型，再次进行烤灯加温，进入B、C浮动压板，实现第二直角定型，最后三组独立压轮两组垂直对C位置加压一组锥度压轮对C端齐与板平面位置小面积接触加压减小胶线可见度，此单元与铣形单元一样配备了伺服电机驱动结构，可接工艺要求在8-40mm范围内输入数字进行A和C之间铣形和压贴同步变化。

The already-mil

led board and glued edge band meet under the main pressing wheel. First, the bonding takes place in the position of A. When the heating lamp softens the edge band, the pre-pressing guide plate will quickly move to shape the straight edge from A to B, and the edge from B to C. Later, the board will be moved through heat lamp to get heated again. Then the straight edge from B to C will be get shaped through the floating platen. Finally, among the three independent pressing wheels, two will get the position of C pressed in a straight manner, and the other one is a tapered pressing wheel which allows the C end to be pressed against the board surface within a small area to reduce the visibility of the glue line. This unit is also installed with a servo-motor structure to allow synchronous changes of milling and pressing between A and C within the range of 8-40mm.

齐头单元

End-trimming unit

本单元主要是对前后两端，多余长度边带进行齐平处理。

This unit is mainly to get the extra edge band trimmed.

粗修、精修单元  

Rough and fine trimming unit

软成型封边在加热包履过程中，边条会有不确定拉伸变宽的现象，所以即使很薄也需要配备粗修单元，削去大部分余量，才能保证精修不出现跳刀现象。

During the heating process, the soft forming edge band may widen. So the rough trimming unit is necessary, even the edge band is thin, to get most extra band trimmed to make sure that the phenomenon of knife jumping won’t appear in the later fine-trimming process.

抛光单元

Polishing unit

在喷射有分离剂，清洁剂的表面进行抛光处理。

The polishing will be done on the board sprayed with separating agent and cleaning agent.
