Description

[根据细则37.2由ISA制定的发明名称]　一种塑料中空格子板封角机 技术领域
本发明涉及一种塑料中空板材挤出生产设备的辅机，特别是一种用于对塑料中空格子板封角的封角机。
背景技术
在塑料加工过程中，需要对塑料制品例如塑料格子板定型，一般的定型装置操作比较烦琐，不能一次成型，需要多人多台设备同时操作，对人员操作要求高，人为干预对成品效果影响大。定型温度、时间无法精确，不能很好的达到定型效果，供料也不是很方便，完全依靠人力来进行单步操作，尤其是不能快速连续对制品进行封圆角，人力成本过高，影响生产效率以及定型效果。
中国专利文献CN 105034350 A公开了一种塑料中空板四角圆弧封边机(专利申请号201510439931.6)，包括导向辊，导向辊上方设有工件压盘，导向辊两侧各设有两个圆弧形的加热成型模具，加热成型模具上设有回位元件，同一侧的两个加热成型模具之间设有模具支架，两侧的模具支架通过导轨连接，导轨上装有滑动轴承，模具支架上连接有驱动装置，模具支架做水平直线运动。半成品的塑料中空板通过导向辊送到工作位时停止，工件压盘压住中空板定位，驱动装置启动，带动模具支架和加热成型模具做沿导轨方向的水平直线往复移动，滑动轴承起支撑导向作用，移动过程中，加热成型模具与塑料中空板的四角接触，四角受热成型，压边成型后工件压盘松开，导向辊将塑料中空板送出。虽然节省人力，提高了工作效率，但加热成型模具与塑料中空板的四角接触的时间和接触压力难以精确控制，不能很好的达到中空格子板的圆角封角定型效果。
发明内容
为了解决以上技术问题，本发明提出了一种塑料中空格子板封角机，用于中空格子板自动圆角或弧角的封边封角，包括一种塑料中空格子板封角机，包括底座(10)，用于输送中空格子板到指定工位的输送单元，用于在封角时固定中空格子板的压紧单元，用于对中空格子板的四角进行热成型封角的成型单元，用于调节中空格子板支撑件宽度与长度的调节单元，以及电气控制单元，其特征是，所述成型单元包括4个分别位于一个长方形的四个角的定型块(11)，定型块(11)有能够使中空格子板四角热成型的圆弧形凹槽(12)。
作为一种改进，本发明的凹槽(12)的截面为U型，能够更好地使加工的塑料中空格子板边缘成型，为了防止定型块对中空格子板的弧角加热封边时引起塑料粘接，本发明在U型凹槽的表面喷涂聚四氟乙烯(特氟龙)，喷涂聚四氟乙烯(特氟龙)后形成不粘涂层，能够使塑料制品成型后边缘整齐漂亮，无压痕无废料堆积。

压紧单元包括通过悬挂横梁(211)固定于悬挂支架(21)的上方中央位置的第二气缸(31)，第二气缸(31)的活塞能够在竖直方向移动并与压杆(32)的一端固定连接，压杆(32)的另一端固定有压紧板(33)，压紧板(33)为水平方向的长方形平面板，压紧板(33)的下方有一与压紧板(33)平行的水平台面(34)，水平台面(34)与底座(10)刚性固定，压紧板(33)连接有4根方向控制杆(35)，方向控制杆(35)垂直于压紧板(33)所在平面，悬挂横梁(211)固定有4个直线轴承(36)，方向控制杆(34)的一端与压紧板(33)连接，另一端套入直线轴承(36)；
调节单元包括横向滑轨副(41)，纵向滑轨副(42)，横向滑轨副(41)和纵向滑轨副(42)均为线性滑轨副，横向滑轨副(41)的横向滑轨条(411)固定于底座(10)并位于底座(10)的两侧，其横向滑块(412)与纵向滑轨副(42)的纵向滑轨条(421)固定连接，纵向滑轨副(42)的纵向滑块(422)上固定有成型单元；
所述成型单元包括，基体(51)，推进气缸(52)，定型块(11)以及凹槽(12)，所述基体(51)固定在纵向滑块(422)上并与推进气缸(52)的缸筒固定，推进气缸(52)的活塞杆与定型块(11)固定连接，定型块(11)上的凹槽(12)开口为圆弧形，圆弧中点所在的半径与推进气缸(52)的活塞杆的轴线平行，所述推进气缸(52)的活塞杆的轴线分别与长方形压紧板(33)的对角线平行。
为了更好地保持加工精度，使得成型单元的定型块(11)的角度更加精确地对准被加工的中空格子板，本发明的塑料中空格子板封角机的成型单元还包括能够调整定型块(11)的角度的角度微调装置(61)。所述角度微调装置(61)包括顶丝(611)，顶丝螺母(612)，微调孔(613)以及微调孔(613)的固定螺丝，顶丝螺母(612)固定在连接板(614)上，定型块(11)由穿过微调孔(613)的固定螺丝固定在连接板(614)上，连接板(614)与推进气缸(52)的活塞杆固定连接，所述微调孔(613)的直径大于固定螺丝的螺杆直径、小于固定螺丝的垫片直径。操作时，先松开微调孔的固定螺丝，使定型块处于自由状态，根据被加工中空格子板的封角的位置，分别旋转2个顶丝，调整定型块的角度，待调整好后，拧紧微调孔的固定螺丝。由于微调孔的直径大于固定螺丝的螺杆直径、小于固定螺丝的垫片直径，因而有一定的角度调整空间可以实现对定型块的角度微调。为了保证调整角度的足够空间，微调孔的直径大于固定螺丝的螺杆直径至少4mm。
为了更加有利于中空格子板在输送到加工位置时的准确快速定位，本发明提出的塑料中空格子板封角机的调节单元还包括能够对中空格子板定位的定位块(43)，定位块分别位于横向导轨和纵向导轨上，使得中空格子板在被输送到指定位置时能够被定位块阻挡并准确定位。所述定位块(43)包括连接部(431)，以及能够在调节旋钮(432)作用下水平移动的定位部(433)，所述连接部(431)分别位于横向滑轨条(411)和纵向滑轨条(421)上。
作为一种改进，本发明所述压紧单元的水平台面(34)上还固定有PVC板，所述PVC板在压紧板(33)和水平台面(34)之间。加装PVC板，使得水平台面(34)上对中空格子板加工面的平整度更高，有利于提高加工质量。
作为一种改进，本发明所述的横向滑块(412)和纵向滑块(422)由减速电机驱动其发生移动，减速电机由变频器控制，牵引输送速度可根据实际生产的即时速度来调节。
发明人在实际中发现，本发明的塑料中空格子板封角机，其凹槽(12)的截面U型的开口的口径与被加工的中空格子板厚度相同时，能够起到最佳的加工效果。例如在加工4mm厚的中空格子板时，取凹槽开口的口径为4mm，如果大于4mm则不易触及被加工的中空格子板，造成烫角加工时热量难以快速传递到中空格子板，如果小于4mm，则由于U型开口的口径尺寸过小，被加工的中空格子板难以快速进入U型凹槽内。作为进一步改进，所属凹槽(12)的截面U型开口边缘切有倒角，防止刮伤人手。

本发明的塑料中空格子板封角机的输送单元包括固定在底座(10)中央上方的悬挂支架(21)，悬挂支架(21)包括悬挂横梁(211)和悬挂立柱(212)，第一气缸(22)与悬挂横梁(211)刚性连接并位于在底座(10)与悬挂横梁(211)之间，第一气缸(22)的活塞与输送胶辊(23)刚性连接并能够在竖直方向往复运动，输送带架(24)固定在底座(10)上方水平放置，输送带架(24)为长方形、其一侧固定有主动胶辊(25)、另一侧固定有从动胶辊(26)，从动胶辊(26)的轴线与输送胶辊(23)的轴线在同一个竖直平面内，主动胶辊(25)与从动胶辊(26)通过输送带(27)连接，主动胶辊(25)与输送电机(28)连接并通过输送带(27)带动从动胶辊(26)同步转动；
压紧单元包括通过悬挂横梁(211)固定于悬挂支架(21)的上方中央位置的第二气缸(31)，第二气缸(31)的活塞能够在竖直方向移动并与压杆(32)的一端固定连接，压杆(32)的 另一端固定有压紧板(33)，压紧板(33)为水平方向的长方形平面板，压紧板(33)的下方有一与压紧板(33)平行的水平台面(34)，水平台面(34)与底座(10)刚性固定，压紧板(33)连接有4根方向控制杆(35)，方向控制杆(35)垂直于压紧板(33)所在平面，悬挂横梁(211)固定有4个直线轴承(36)，方向控制杆(34)的一端与压紧板(33)连接，另一端套入直线轴承(36)；
调节单元包括横向滑轨副(41)，纵向滑轨副(42)，横向滑轨副(41)和纵向滑轨副(42)均为线性滑轨副，横向滑轨副(41)的横向滑轨条(411)固定于底座(10)并位于底座(10)的两侧，其横向滑块(412)与纵向滑轨副(42)的纵向滑轨条(421)固定连接，纵向滑轨副(42)的纵向滑块(422)上固定有成型单元；
所述成型单元包括，基体(51)，推进气缸(52)，定型块(11)以及凹槽(12)，所述基体(51)固定在纵向滑块(422)上并与推进气缸(52)的缸筒固定，推进气缸(52)的活塞杆与定型块(11)固定连接，定型块(11)上的凹槽(12)开口为圆弧形，圆弧中点所在的半径与推进气缸(52)的活塞杆的轴线平行，所述推进气缸(52)的活塞杆的轴线分别与长方形压紧板(33)的对角线平行。能够调整定型块(11)的角度的角度微调装置(61)包括顶丝(611)，顶丝螺母(612)，微调孔(613)以及微调孔(613)的固定螺丝，顶丝螺母(612)固定在连接板(614)上，定型块(11)由穿过微调孔(613)的固定螺丝固定在连接板(614)上，连接板(614)与推进气缸(52)的活塞杆固定连接，所述微调孔(613)的直径大于固定螺丝的螺杆直径、小于固定螺丝的垫片直径。操作时，先松开微调孔的固定螺丝，使定型块处于自由状态，根据被加工中空格子板的封角的位置，分别旋转2个顶丝，调整定型块的角度，待调整好后，拧紧微调孔的固定螺丝。为了保证调整角度的足够空间，微调孔的直径大于固定螺丝的螺杆直径至少4mm。
利用本发明的塑料中空格子板封角机进行生产操作时，踩下脚踏开关，第一气缸(22)带动输送胶辊(23)向下运动压紧中空格子板制品，输送胶辊(23)采用挂硅胶辊，能够防止制品打滑，第一气缸(22)动作快慢由气缸上节流阀控制，同时，输送电机(28)启动，带动主动胶辊(25)通过输送带(27)带动从动胶辊(26)同步转动输送格子板制品，电气控制单感应到塑料制品达到位置时，第一气缸(22)抬起，同时输送带停止输送。输送速度可根据实际生产的即时速度来调节。
输送带停止输送后，压紧单元的第二气缸(31)向下移动并带动压杆(32)将中空格子板制品压紧在水平台面(34)上。压紧板(33)连接有4根方向控制杆(35)，方向控制杆(34)的一端与压紧板(33)连接，另一端套入直线轴承(36)，由于直线轴承(36)的直线稳定性强，可以保证压紧板(33)在向下移动及压紧过程中的平面水平。
压紧后，定型块(11)由四个超薄铝制推进气缸(52)推进与被加工的中空格子板制品接触，定型块(11)上的凹槽(12)经过电加热的圆弧形开口将被加工的中空格子板制品的四角加热成型封角。成型时间根据不同塑料，不同厚度可以调节温度，以及成型时间。达到成型时间后定型块(11)由推进气缸(52)拉回初始位置，同时压紧单元的第二气缸(31) 抬起，第一气缸(22)向下运动，输送胶辊(23)向下运动重新压紧中空格子板制品，输送电机(28)启动，带动主动胶辊(25)通过输送带(27)带动从动胶辊(26)同步转动输送已经加工完成的格子板制品撤回到初始位置，完成一次成型操作。所有动作由微电脑程序控制，发出电信号，控制执行部件。
为适应不同长宽规格的中空格子板制品，操作时，可以调节本发明的调节单元包括横向滑轨副(41)的横向滑块(412)、纵向滑轨副(42)的纵向滑块(422)，调节过程由减速电机驱动，到达合适位置时减速电机停止运行，可以自动固定滑块位置；也可以在调节到合适位置后另行将横向滑块(412)、纵向滑块(422)分别固定，适用于加工的中空格子板制品尺寸范围广，能够实现各种中空格子板的连续快速成型。
为了防止调试完成后的工作过程中，顶丝(611)与顶丝螺母(612)之间产生的相对转动，造成部件位置精度降低，本发明的一种改进是，在调试完成后，将顶丝(611)与顶丝螺母(612)使用热缩管封装为一体，阻止顶丝(611)与顶丝螺母(612)之间发生相对转动。同样的问题也会出现在调节旋钮(432)与定位部(433)之间，使用同样的封装方式，在调试完成后，将调节旋钮(432)与定位部(433)使用热缩管封装为一体。热缩管是一种特制的聚烯烃材质热收缩套管，也可以叫做EVA材质的。外层采用优质柔软的交联聚烯烃材料及内层热熔胶复合加工而成的，外层材料有绝缘防蚀、耐磨等特点，内层有低熔点、防水密封和高粘接性等优点。热缩管所用材料在室温下是玻璃态，加热后变成高弹态。使用时把热缩管加热到高弹态，施加载荷使其扩张，在保持扩张的情况下快速冷却，使其进入玻璃态，这种状态就固定住了。pet热缩管(聚酯热缩套管)无毒环保，不会对人体和环境造成危害。
本发明的有益效果在于：能够一键启动，自动连续快速对塑料板材进行送料、成型、成型后自动输出塑料制品，成型后无压痕、无废料堆积、整齐漂亮。安装更加简易，操作更加方便、安全。自动化封圆角装置减少了人员操作过程，全部采用自动化控制，时间、温度精确控制，速度采用变频调速控制，操作人员只需要一键控制，剩余动作全部自动进行，速度快，行进稳定，可连续快速对制品进行定型封圆角，解决了人力成本过高，定型效果好，生产效率大幅提高。
