一种包装袋封边热压装置

Abstract

本申请公开了一种包装袋封边热压装置，涉及袋封边热压领域，其包括热压机本体，所述热压机本体的表面一侧安装有基础热压板，所述基础热压板的表面一侧设置有用于扩展基础热压板热压范围的扩展热压板，所述基础热压板靠近扩展热压板的表面开设有拼接槽，所述基础热压板与扩展热压板之间设置有用于将基础热压板与扩展热压板拼接在一起的拼接组件，本申请通过拼接组件将扩展热压板与基础热压板快速拼接，配合M形抵接槽与抵接块的大面积接触设计，既能通过增减扩展热压板数量适应不同封边长度的包装袋，又通过定位组件定位保证拼接后结构稳定，从而在热压过程中无松动或偏移，解决了传统热压装置热压长度固定、无法适配长尺寸包装袋的问题。

The splicing block (42) has an abutment groove (421) on one side of its surface to increase the splicing area between the splicing block (42) and the splicing groove (21). An abutment block (211) that abuts against the abutment groove (421) is fixed inside the splicing groove (21). A positioning block (41) is fixed on one side of the surface of the splicing block (42) near the surface of the base hot press plate (2). A positioning assembly (5) is disposed on one side of the surface of the extended hot press plate (3) to position the positioning block (41) inside the splicing groove (21).

2. The apparatus according to claim 1, wherein: The positioning block (41) and the splicing block (42) are fixed with an insert (43) on one side of their surfaces. The insert (43) is fixed with a conductive sheet (431) on one side of its surface. The extended hot press plate (3) is provided with a slot (22) that is compatible with the insert (43) on one side of its surface near the base hot press plate (2). The slot (22) is fixed with a conductive sheet (221) that abuts against the conductive sheet (431).

3. The apparatus of claim 1, wherein: The positioning component (5) includes a drive plate (51) that abuts against one side of the surface of the base hot press plate (2). The drive plate (51) is fixed with a positioning rod (52) that is slidably disposed on one side of the surface of the base hot press plate (2) near the surface of the base hot press plate (2). The positioning rod (52) is used to position the positioning block (41).

4. The apparatus according to claim 3, wherein: The driving plate (51) has a limiting plate (53) fixed on both sides of its surface, which is slidably disposed inside the base hot press plate (2). The limiting plate (53) is used to limit the positioning rod (52).

5. The apparatus of claim 4, wherein: The limiting plate (53) has an elastic element (531) fixed inside the base hot press plate (2) on one side of the surface near the drive plate (51). The elastic element (531) is used to control the positioning rod (52) to automatically reset.

6. The packaging bag sealing hot pressing device according to claim 1, characterized in that: The abutment groove (421) is composed of multiple M-shaped grooves, and the abutment block (211) is composed of M-shaped blocks that are adapted to the abutment groove (421).

7. The apparatus of claim 2 wherein: The conductive sheet 2 (431) and the abutment block (211) are both made of T2 copper.

8. The apparatus of claim 1, wherein: The base hot press plate (2) and the extended hot press plate (3) are equipped with heating elements for heating.
