Description

Technical Field

[0001] The present invention relates to the technical field of embossing devices, and particularly relates to a plastic packaging bag embossing device. Background Art

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

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

[0004] When embossing plastic packaging bags made of some soft PVC materials, due to the fact that the material has a certain plasticity and is not too soft at the same time, the plastic packaging bag may have a certain curvature after forming. When placing the unprocessed plastic packaging bag on the embossing device and performing embossing treatment on it, when the pressing plate moves downward and contacts the arc surface of the plastic packaging bag, when the horizontal pressing plate contacts the plastic packaging bag with a curvature, the direction of the acting force generated may have other directions in addition to vertically downward. When there are acting forces other than the vertically downward acting force, the embossing position on the surface of the plastic packaging bag will deviate, resulting in inaccurate embossing positions and affecting the embossing quality. Therefore, this application proposes a plastic packaging bag embossing device to solve the above problems. Summary of the Invention

Detailed implementation manner

[0031] The present invention will be further described in detail below in conjunction with embodiments:

[0032] Embodiment 1

[0033] As Figures 1-9As shown in the figure, the present invention provides an embossing device for plastic packaging bags, which includes an embossing machine main body 1. An operation button 2 is movably connected to the front surface of the embossing machine main body 1. A slide rail 3 is fixedly connected to the middle of the embossing machine main body 1. An operation table 4 is movably connected to the slide rail 3. A hydraulic component 5 is movably connected to the embossing machine main body 1. An embossing template 27 is movably connected to the top of the operation table 4. A moving handle 10 is fixedly connected to the bottom of the operation table 4. The connection relationships among the embossing machine main body 1, the operation button 2, the slide rail 3, the operation table 4, the hydraulic component 5, the moving handle 10 and various structures are all prior arts and will not be described in detail in this application. An installation groove 6 is formed on the operation table 4. An adjusting air plate 11 is movably connected to the inner wall of the installation groove 6. The adjusting air plate 11 and the installation groove 6 are movably connected in a detachable installation manner. A negative pressure air outlet 12 is formed on the outer surface of the adjusting air plate 11. An air hopper 7 covering the installation groove 6 is fixedly connected to the lower surface of the operation table 4. An air duct 8 is fixedly connected to the lower surface of the air hopper 7. One end of the air duct 8 is fixedly connected to a negative pressure fan 9. The negative pressure fan 9 is fixedly connected to the bottom of the operation table 4. First, the adjusting air plate 11 is installed and connected to the installation groove 6. 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. Then, under the action of the negative pressure fan 9 and the air duct 8, the air in the gap between the plastic packaging bag to be processed and the adjusting air plate 11 is sucked out, generating a downward adsorption force, so that the plastic packaging bag to be processed is as close as possible to the adjusting air plate 11. Then, the embossing template 27 is placed in a suitable position, and the moving handle 10 is toggled to drive the entire operation table 4 to slide along the slide rail 3 to the directly below of the hydraulic component 5 until the hydraulic component 5 is aligned with the embossing template 27. Then, the hydraulic component 5 moves downward to apply a vertically 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 avoids the problem that other directional forces may be generated when the pressing plate is directly pressed down, resulting in deviation of the embossing position, inaccurate embossing position, and affecting the embossing quality.

[0034] Further, two pressing plates 15 are symmetrically and movably connected to the upper surface of the operation table 4 along the installation groove 6. The cross-section of the pressing plate 15 is in an inverted L shape. Installation blocks 18 are fixedly connected to both ends of each pressing plate 15. The installation blocks 18 are movably connected to connecting columns 20 through fixing bolts 19. A driving mechanism for driving the two pressing plates 15 to move towards or away from each other is provided between the operation table 4 and the connecting columns 20. First, the distance between the two pressing plates 15 is adjusted to be the same as the width of the plastic packaging bag to be processed. Then, the plastic packaging bag to be processed is inserted between the two pressing plates 15, and all the gaps formed between the edges of the plastic packaging bag and the pressing plates 15 and the operation table 4 are fitted, further limiting the position of the plastic packaging bag to be processed, which is convenient for subsequent embossing processing.

[0035] Further, the driving mechanism includes a plurality of limiting sliding grooves 23 formed on the outer surface of the operating table 4. A connecting groove 21 is formed at the bottom of each connecting column 20. The thread directions of the two connecting grooves 21 symmetrically arranged along the installation groove 6 are opposite. A double-headed screw rod 22 is movably connected through the inner walls of the two symmetrically arranged connecting grooves 21 along the installation groove 6. Both ends of the double-headed screw rod 22 are movably connected to the inner wall of the limiting sliding groove 23. Positive threads and reverse threads respectively adapted to the two symmetrically arranged connecting grooves 21 are formed on the outer surface of the double-headed screw rod 22 located inside the limiting sliding groove 23. A driving device 24 is fixedly connected to the side surface of the operating table 4. The driving device 24 is a prior art and includes a driving structure such as a motor and a connecting member. The output shaft of the driving device 24 is fixedly connected to one end of the double-headed screw rod 22. By driving the double-headed screw rod 22 to rotate through the driving device 24, the two connecting columns 20 connected to the same double-headed screw rod 22 can move towards or away from each other, so as to adapt to plastic packaging bags to be processed with different widths.

[0036] Further, a scale three 25 is arranged on the outer surface of the operating table 4 on one side of the limiting sliding groove 23. The distance between the two limiting sliding grooves 23 symmetrically distributed along the installation groove 6 is fixed and measurable. Through the setting of the scale three 25, when the two pressing plates 15 move towards or away from each other, the 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.

[0037] Further, there are various types of pressing plates 15. They can be straight, or can be replaced with a bent pressing plate 17, etc. The bent pressing plate 17 has a certain radian and can fit a packaging bag with a radian at the edge. It can also be other forms that fit the radian of the packaging bag, and the appropriate form can be selected according to actual needs.

[0038] Further, fixing plates 33 are fixedly connected to both sides of the operating table 4. A side sliding rod 32 is fixedly connected to each fixing plate 33. Two U-shaped sliding rods 26 are movably connected to the outer surfaces of the two side sliding rods 32 on both sides. The lower surface of the U-shaped sliding rod 26 is movably connected to the upper surface of the pressing plate 15. An elastic connection component for movably connecting with the embossing template 27 is arranged on the two U-shaped sliding rods 26. After the plastic packaging bag to be processed is placed, adjust the distance between the two U-shaped sliding rods 26 to be consistent with the width of the embossing area. Then select the corresponding embossing template 27 and hang it on the U-shaped sliding rod 26, and horizontally move it to a suitable position. With the cooperation of the elastic connection component, the plastic packaging bag to be processed at the bottom can be embossed through the embossing template 27.

[0039] Further, the elastic connection component includes a hanging plate 28 movably connected to both U-shaped sliding rods 26. An activity groove 29 is formed on the outer surface of the embossing template 27. A connection block 34 is movably connected to the inner wall of the activity groove 29. The connection block 34 is fixedly connected to the hanging plate 28. A limiting sliding rod 30 is movably connected through the connection block 34. Both ends of the limiting sliding rod 30 are fixedly connected to the inner wall of the activity groove 29. A spring 31 is sleeved on the outer surface of the limiting sliding rod 30 above the connection block 34. Under the action of the downward movement of the hydraulic component 5, the embossing template 27 moves downward, causing the connection block 34 to move relatively upward along the limiting sliding rod 30, compressing the spring 31 and causing it to undergo elastic deformation. After the pressure of the hydraulic component 5 on the embossing template 27 is removed, the embossing template 27 rebounds under the action of the compressed spring 31, causing the lower surface of the embossing template 27 to separate from the plastic protection bag to be processed.

[0040] Further, scale marks one 14 are provided on both sides of the installation groove 6 on the outer surface of the operating table 4. Scale marks two 16 are provided on each pressing plate 15. The scale marks one 14 and the scale marks two 16 correspond one by one. Scale marks four are provided on the upper surface of the U-shaped sliding rod 26. Through the action of the scale marks one 14, when the plastic packaging bag to be processed is placed on the operating table 4, one side edge thereof is aligned with the scale marks one 14, so that the scale range corresponding to the position of the embossing area on the plastic packaging bag to be processed can be determined. Therefore, when moving the two U-shaped sliding rods 26, through the indication of the pressing plate 15, the distance between the two U-shaped sliding rods 26 is aligned with the embossing area on the plastic packaging bag to be processed. Then, through the action of the scale marks four on the U-shaped sliding rod 26, the embossing template 27 can be moved along the U-shaped sliding rod 26 to a specific position, so that the embossing template 27 can fit as closely as possible to the area to be embossed on the plastic packaging bag, thereby improving the accuracy of the embossing position to a certain extent.

[0041] Further, there are multiple types of adjusting air plates 11. The difference between the multiple types of adjusting air plates 11 lies in the different numbers of negative pressure air vents 12 opened. The adsorption positions generated by different numbers of negative pressure air vents 12 are wider, and the plastic packaging bag to be processed placed can fit better with the adjusting air plate 11 and the upper surface of the operating table 4, and can be selected according to actual needs.

[0042] Further, a buckling groove 13 is formed on each adjusting air plate 11, which is convenient for replacing different adjusting air plates 11.

[0043] Further, there are multiple types of embossing templates 27, and different embossing types can be selected according to needs, including various types such as different pattern types and different embossing area sizes. The multiple embossing templates 27 are all prior arts.

[0044] Next, the working principle of the plastic packaging bag embossing device will be specifically described.

[0045] AsFigures 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.
