Description

Technical Field

[0001] The invention relates to the technical field of embossing devices, in particular to an embossing device for a plastic packaging bag. Background Art

[0002] Embossing machines are mainly used for hemming, welding, melting and embossing of synthetic fiber fabrics. For example: hemming of three-dimensional non-woven bags; laminating of patterns on the top and edges of non-woven bags; melting and cutting of Velcro; embossing of PVC materials; embossing and welding on clothing, etc.

[0003] PVC is a polymer formed by the free radical polymerization mechanism of vinyl chloride monomer (VCM) in the presence of initiators such as peroxides and azo compounds or under the action of light or heat. It is the third largest synthetic polymer plastic in the world. There are two types of PVC: hard and soft. Hard polyvinyl chloride is used for building pipes, doors and windows. It is also used to make plastic bottles, packaging, bank cards or membership cards. Adding plasticizers can make PVC softer and more flexible. It can be used for pipes, cable insulation, flooring, signs, phonograph records, inflatable products and rubber substitutes.

[0004] When embossing plastic packaging bags made of some PVC soft materials, the material has a certain plasticity but is not too soft, so the plastic packaging bags may have a certain curvature after forming. When the unprocessed plastic packaging bags are placed on the embossing device and embossed, the pressure plate moves downward and contacts the curved surface of the plastic packaging bag. When the horizontal pressure plate contacts the curved plastic packaging bag, the force generated may generate forces in other directions in addition to the vertical downward force. When there are other forces except the vertical downward force, the embossing position on the surface of the plastic packaging bag will deviate, making the embossing position inaccurate and affecting the embossing quality.

First, the adjusting air plate 11 and the mounting groove 6 are installed and connected, and then the plastic packaging bag to be processed is placed on the adjusting air plate 11, and the negative pressure air outlet 12 is covered, and then the air in the gap between the plastic packaging bag to be processed and the adjusting air plate 11 is sucked out through the action of the negative pressure fan 9 and the air duct 8, so as to generate a downward adsorption force, so that the plastic packaging bag to be processed and the adjusting air plate 11 fit as closely as possible, and then the embossing template 27 is placed in a suitable position, and the moving handle 10 is turned to drive the operating table 4 as a whole to drive the slide rail 3 to slide directly below the hydraulic assembly 5 until the hydraulic assembly 5 is aligned with the embossing template 27, and then the hydraulic assembly 5 is moved downward to apply a vertical downward force to the embossing template 27, thereby completing the embossing process of the plastic packaging bag to be processed. To a certain extent, it is avoided that other directions of force may be generated when the pressing plate is directly pressed down, causing the embossing position to deviate, resulting in inaccurate embossing position and affecting the embossing quality.

[0023] Furthermore, the upper surface of the operating table 4 is symmetrically and movably connected with two pressing plates 15 along the mounting groove 6. The cross-section of the pressing plate 15 is inverted L-shaped. Both ends of each pressing plate 15 are fixedly connected with a mounting block 18. The mounting block 18 is movably connected with a connecting column 20 through a fixing bolt 19. A driving mechanism for driving the two pressing plates 15 to move toward or away from each other is arranged between the operating table 4 and the connecting column 20. First, the distance between the two pressing plates 15 is adjusted to be consistent with the width of the plastic packaging bag to be processed, and then the plastic packaging bag to be processed is inserted between the two pressing plates 15. The gap formed between the edge of the plastic packaging bag and the pressing plate 15 and the operating table 4 is completely fitted, and the position of the plastic packaging bag to be processed is further limited, which is convenient for subsequent embossing processing.

[0024] Furthermore, the driving mechanism includes a plurality of limiting slide grooves 23 provided on the outer surface of the operating table 4, a connecting groove 21 is provided at the bottom of each connecting column 20, the thread directions of the two connecting grooves 21 symmetrically arranged along the mounting groove 6 are opposite, and a double-headed screw 22 is movably connected to the inner wall of the two connecting grooves 21 symmetrically arranged along the mounting groove 6, and both ends of the double-headed screw 22 are movably connected to the inner wall of the limiting slide groove 23, and the double-headed screw 22 is located on the outer surface of the limiting slide groove 23 and is provided with positive threads and reverse threads respectively matched with the two symmetrical connecting grooves 21, and a driving device 24 is fixedly connected to the side of the operating table 4. The driving device 24 is the existing technology, including a driving structure such as a motor and a connecting member, and the output shaft of the driving device 24 is fixedly connected to one end of the double-headed screw 22, and the double-headed screw 22 is driven to rotate by the driving device 24, so as to drive the two connecting columns 20 connected with the same double-headed screw 22 to move toward or away from each other, thereby adapting to plastic packaging bags to be processed of different widths.

[0025] Furthermore, a scale three 25 is provided on the outer surface of the operating table 4 on one side of the limit slide groove 23, and the distance between the two limit slide grooves 23 symmetrically distributed along the mounting groove 6 is fixed and measurable. By setting the scale three 25, when the two pressing plates 15 move toward or away from each other, their moving distance can be determined, so that the distance between the two pressing plates 15 is consistent with the width of the plastic packaging bag to be processed.

[0026] Furthermore, there are multiple types of pressure plates 15, which can be straight or replaced by a bent pressure plate 17, etc., wherein the bent pressure plate 17 has a certain curvature and can fit the packaging bag with a curved edge, or can have other shapes that fit the curvature of the packaging bag. The appropriate shape can be selected according to actual needs.

[0027] Furthermore, both sides of the operating table 4 are fixedly connected with fixed plates 33, and each fixed plate 33 is fixedly connected with a side sliding bar 32. Two U-shaped sliding bars 26 are movably connected to the outer surfaces of the side sliding bars 32 on both sides, and the lower surface of the U-shaped sliding bar 26 is movably connected to the upper surface of the pressing plate 15. The two U-shaped sliding bars 26 are provided with elastic connecting components movably connected to the embossing template 27. When the plastic packaging bags to be processed are placed, the distance between the two U-shaped sliding bars 26 is adjusted to be consistent with the width of the embossing area, and then the corresponding embossing template 27 is selected to be hung on the U-shaped sliding bar 26 and moved laterally to a suitable position. With the action of the elastic connecting component, the plastic packaging bags to be processed at the bottom can be embossed through the embossing template 27.

[0028] Furthermore, the elastic connection component includes a hanging plate 28 movably connected to the two U-shaped slide bars 26, a movable groove 29 is opened on the outer surface of the embossing template 27, and a connecting block 34 is movably connected on the inner wall of the movable groove 29, the connecting block 34 is fixedly connected to the hanging plate 28, the connecting block 34 passes through the movably connected limiting slide bar 30, the two ends of the limiting slide bar 30 are fixedly connected to the inner wall of the movable groove 29, and the limiting slide bar 30 is located on the outer surface of the upper part of the connecting block 34 and is sleeved with a spring 31. The embossing template 27 moves downward under the action of the downward moving hydraulic component 5, so that the connecting block 34 moves relatively upward along the limiting slide bar 30, compressing the spring 31 to cause it to undergo elastic deformation. When the pressure of the hydraulic component 5 on the embossing template 27 is removed, the embossing template 27 rebounds under the action of the compression spring 31, so that the lower surface of the embossing template 27 is separated from the processed plastic protective bag.

[0030] Furthermore, there are multiple types of regulating air plates 11. The difference between the multiple regulating air plates 11 is that the numbers of the negative pressure air vents 12 opened are different. The adsorption positions produced by the different numbers of negative pressure air vents 12 are wider, which can make the plastic packaging bags to be processed fit better with the upper surface of the regulating air plate 11 and the operating table 4. The selection can be made according to actual needs.

[0032] Furthermore, there are multiple types of embossing templates 27, and different embossing types can be selected according to needs, including multiple types with different pattern types and different embossing area sizes. The multiple embossing templates 27 are all existing technologies.

[0033] The working principle of the plastic packaging bag embossing device is described in detail below.

[0034] like Figure 1-9 As shown, firstly, a suitable regulating air plate 11 is selected to be connected to the mounting groove 6, and then, according to the shapes of both sides of the plastic packaging bag to be processed, a suitable pressing plate 15 is selected to be connected to the connecting column 20 through the mounting block 18 and the fixing bolt 19, and then the double-headed screw 22 is driven to rotate by the driving device 24, so as to drive the two connecting columns 20 connected with the same double-headed screw 22 to move toward or away from each other, so that the distance between the two pressing plates 15 is consistent with the width of the plastic packaging bag to be processed, and then the plastic packaging bag to be processed is inserted between the two pressing plates 15, so that the edge of the plastic packaging bag and the gap formed between the pressing plate 15 and the operating table 4 are completely fitted, and then, through the action of the negative pressure fan 9 and the air duct 8, the The air in the gap between the plastic packaging bag to be processed and the regulating air plate 11 is sucked out to generate a downward adsorption force, so that the plastic packaging bag to be processed and the regulating air plate 11 are as close as possible, and the distance between the two U-shaped slide bars 26 is adjusted to be consistent with the width of the embossing area, and then the corresponding embossing template 27 is selected to be hung on the U-shaped slide bar 26, and moved horizontally to a suitable position, and the moving handle 10 is turned to drive the operating table 4 as a whole to drive the slide rail 3 to slide directly below the hydraulic component 5 until the hydraulic component 5 is aligned with the embossing template 27, and then the hydraulic component 5 is moved downward to apply a vertical downward force to the embossing template 27, thereby completing the embossing process of the plastic packaging bag to be processed.
