Positioning and pressing device

Abstract

The utility model belongs to the technical field of packaging bag production, and provides a positioning and pressing device which comprises a working table, a mounting frame, a moving assembly and a pressing assembly. The mounting frame is driven to move through the moving assembly, the mounting frame moves to drive the pressing roller to move through the mounting plate and the mounting rod, so that the position of the pressing roller is adjusted, after the position of the pressing roller is adjusted, the mounting plate can be driven by rotating the driving part to drive the mounting rod and the pressing roller to slide in the direction perpendicular to the working table, and therefore the height of the pressing roller is adjusted. The height of the pressing roller is convenient to adjust, by arranging a spring, when the mounting plate drives the pressing roller to move downwards to press the air bubble film packaging bag, if the pressing force is too large, the mounting plate moves downwards to extrude the spring so that the spring can be shrunk, and therefore the situation that the pressing roller continues to move downwards along with the mounting plate, and the air bubble film packaging bag is crushed and damaged is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a positioning and pressing device. Background Art

[0002] Bubble film packaging bags are a new type of plastic packaging material that is light, transparent, non-toxic and odorless. Since the middle layer of the bubble film is filled with air, it is light, transparent, elastic, and has the properties of sound insulation, shock resistance and wear resistance. It is widely used in shock-resistant cushioning packaging for electronics, ceramics, glass products and precision instruments. In the production process of bubble film packaging bags, in order to improve the edge sealing effect, a positioning and pressing device must be set at the front end of the edge sealing.

[0003] For example, the Chinese patent No. 202121860661.3 discloses a bubble film packaging bag positioning and clamping device, including a frame, a positioning rod connected in the middle of the frame, an adjustment block is provided on the positioning rod, and the adjustment block is connected to a pressing roller; movable gears are provided on both sides of the frame, one of the movable gears is connected to the adjusting handle, and the movable gear is connected to the gear guide rails on both sides of the work surface to realize forward and backward displacement movement; fixed blocks are also connected on both sides of the frame, and the fixed blocks are connected to elastic handles.

[0004] When adjusting the height of the pressing roller, the existing positioning and pressing device needs to loosen the bolts and then move the pressing roller. When the pressing roller is moved to a suitable height, the bolts are tightened to fix the pressing roller. The height adjustment of the pressing roller is inconvenient. At the same time, the pressing roller is not provided with a buffer structure, which easily causes damage to the bubble film packaging bag during the process of the pressing roller pressing the bubble film packaging bag. Therefore, in view of the above technical problems, a positioning and pressing device is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a positioning and pressing device, which is convenient for adjusting the height of the pressing roller and can prevent the bubble film packaging bag from being damaged when the bubble film packaging bag is pressed.
