Description

Technical Field

[0001] This invention relates to the field of packaging bag manufacturing technology, and in particular to a semi-finished product cutting device for manufacturing composite packaging bags. Background Technology

[0002] When manufacturing composite packaging bags, the finished blanks need to be cut to adjust the semi-finished blanks to the appropriate size. During the cutting process, the blanks move on the cutting platform, and the cutting blades are fixed at the edges of the blanks to trim the edges of the blanks that have passed through the cutting blades.

[0003] However, currently, the edge-cutting equipment for raw materials used in packaging bag manufacturing lacks the ability to fix and flatten the material edges during cutting. As a result, the material is prone to edge shrinkage and wrinkling during cutting, which can easily lead to uneven edges. Summary of the Invention

[0004] In view of this, the present invention provides a semi-finished product cutting device for manufacturing composite packaging bags, which has a mechanism for fixing, flattening and stretching the edge of the material. By flattening and stretching the material, the flatness of the cutting area is improved, and the distance between the two cutting machines can be adjusted according to the processing needs.

[0007] Optionally, the outer upper surface of the movable cutting platform is provided with a C-shaped groove. The movable cutting platform includes: an adjustment frame, which is disposed on the inner side of the movable cutting platform; and a cutting drive, which is fixedly connected to the movable cutting platform and is connected to and drives the cutting wheel cutter.

[0008] Optionally, the adjusting frame includes a movable slide groove, which is located at the upper end of the adjusting frame; an adjusting screw hole is located at the upper end of the adjusting frame, and the adjusting screw hole is located above the movable slide groove.

[0009] Optionally, a rubber protective layer is provided on the outer surface of the middle section of the outlet pressure roller, and the outlet pressure roller includes an anti-slip roller end, which is fixedly connected to both ends of the outlet pressure roller, and the surface of the anti-slip roller end is provided with anti-slip ridges.

[0010] Optionally, the outer surface of the middle section of the inlet pressure roller is provided with a rubber protective layer, and there are two spiral side push shafts. The two spiral side push shafts are fixedly connected to the front end and the rear end of the inlet pressure roller, respectively. The spiral side push shaft at the front end is left-handed and the spiral side push shaft at the rear end is right-handed. The spiral groove cross section of the spiral side push shaft is a semi-circular structure. Five flattening wheels are rotatably connected to the side flattening frame. Seven wheel body driven protrusions are distributed on the wheel body. The wheel body driven protrusions are semi-circular protrusions, and the upper wheel body driven protrusion is located in the spiral groove of the spiral side push shaft.

[0011] Beneficial effects

[0012] According to various embodiments of the present invention, the material cutting device has a mechanism for fixing, flattening and stretching the edge of the material compared with the conventional cutting device. By flattening and stretching the material, the flatness of the cutting area is improved, and the distance between the two cutting machines can be adjusted according to the processing needs.

[0013] In addition, the support beam is an arched frame structure, which is easy to fix and connect to the cutting conveyor platform, and to support and install the mechanism on the beam. The side guide beam is a beam with a raised strip structure on the upper surface, which facilitates the guidance and support of the movable cutting platform. The guide hole is movably sleeved on the guide column, which guides the lifting end platform through the guide column. Through the action of the tension spring, the lifting end platform is pulled down and tightened, so that the outlet pressure roller and the inlet pressure roller connected to it have a certain clamping force on the processed material, and the material is better clamped and flattened.

[0014] In addition, the rubber protective layer on the exit pressure roller can play an anti-slip role on the surface between the exit pressure roller and the material. When the material moves, the friction drives the exit pressure roller to rotate, and the anti-slip roller end further presses the cutting waste at the edge of the material, thus preventing the material at the cutting position from being deformed due to the cutting edge falling off. This setting fixes the material after cutting, further improving the cutting accuracy.

[0015] In addition, the driven gear is driven by the drive component, which drives the spacing adjustment shaft to rotate. Since the adjustment thread at the front end is left-handed and the adjustment thread at the rear end is right-handed, when the spacing adjustment shaft rotates, the helical transmission effect of the adjustment thread and the adjustment screw hole can simultaneously drive the movable cutting platforms on both sides to move towards the middle or to both sides at the same time, thereby changing the spacing between the two cutting wheel blades. By using the external control mechanism of the spacing adjustment drive component, the position of the movable cutting platform can be better controlled, making it easier to adjust the cutting edge size according to production needs.

[0016] Furthermore, through the cooperation of the imported pressure roller and the flattening wheel, when the material moves to the left on the existing trimming conveyor table, the upper surface of the material contacts the rubber coating of the imported pressure roller, and the friction drives the imported pressure roller to rotate. The imported pressure roller not only compresses the material but also drives the two spiral side push shafts to rotate. When the spiral side push shafts rotate, the driven protrusions on the front and rear flattening wheels engage with the spiral grooves of the two spiral side push shafts. The rotation of the spiral side push shafts drives the driven protrusions on the wheels to move, causing the flattening wheels to rotate. Due to the spiral at the front end... The side push shaft is left-handed. When the spiral side push shaft rotates clockwise, it drives the driven protrusion of the upper wheel to move backward, causing the flattening wheel to rotate. The driven protrusion of the wheel below the flattening wheel then pushes forward, thus flattening the front edge of the material. Similarly, the rear spiral side push shaft is right-handed. In the same way, it drives the rear flattening wheel to rotate, and the driven protrusion of the rear flattening wheel pushes the edge of the material backward, thus flattening the material. After the material is flattened, it enters the material cutting area, preventing the material from deforming during transportation and affecting the quality of the material cutting edge.

[0039] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0040] Example: Please refer to Figures 1 to 9 :

[0041] This invention proposes a semi-finished product cutting device for manufacturing composite packaging bags, comprising: a support beam 2, the lower ends of the two legs of the support beam 2 being fixedly connected to the front and rear sides of the edge-cutting conveyor table 1; two sets of guide columns 201, the two sets of guide columns 201 being fixedly connected to the front and rear sides of the support beam 2 respectively; each set of guide columns 201 having two parallel cylindrical rods; a tension spring 2011 being sleeved on the cylindrical rod of the guide column 201, the lower end of the tension spring 2011 being fixedly connected to the lower end of the guide column 201; and side guide beams 202 located on the front and rear sides of the support beam 2; the support beam 2 is an arched frame structure, facilitating fixed connection to the edge-cutting conveyor table 1 and supporting and installing the upper mechanism of the beam; the side guide beams 202 are beams with a raised strip structure on their upper surface. The movable cutting platform 6 is guided and supported by the side guide beam 202. Two lifting end platforms 3 are provided, slidably connected to the front and rear sides of the support beam 2 respectively. The outlet pressure roller 4 is rotatably connected between the two lifting end platforms 3, with the outlet pressure roller 4 located on the left side of the lifting end platform 3. The spacing adjustment shaft 5 is rotatably connected to the upper part of the support beam 2 via bearings, and the driven gear 501 is fixedly connected to the middle of the spacing adjustment shaft 5. Two adjusting threads 502 are fixedly connected to the front and rear ends of the spacing adjustment shaft 5 respectively. A C-shaped groove is provided on the outer upper surface of the movable cutting platform 6. The movable cutting platform 6 includes: an adjustment frame 601, which is located on the inner side of the movable cutting platform 6, and a movable slide 6011 is provided on the adjustment... The upper end of the adjustment frame 601; the adjustment screw hole 6012 is opened at the upper end of the adjustment frame 601, and the adjustment screw hole 6012 is located above the movable slide groove 6011; the cutting drive component 602 is fixedly connected to the movable cutting platform 6, and the cutting drive component 602 is connected to and drives the cutting edge wheel cutter 603; the drive component drives the driven gear 501, which drives the spacing adjustment shaft 5 to rotate. Since the front adjustment thread 502 is left-handed and the rear adjustment thread 502 is right-handed, when the spacing adjustment shaft 5 rotates, through the helical transmission effect of the adjustment thread 502 and the adjustment screw hole 6012, the movable cutting platforms 6 on both sides can be driven to move simultaneously to the middle or simultaneously to both sides, thereby changing the two cutting edge wheel cutters 603. The spacing adjustment drive 9, through an external control mechanism, allows for better control of the position of the movable cutting platform 6, facilitating adjustment of the cutting edge size according to production needs. The spacing adjustment drive 9 is fixedly connected to the concave beam position on the middle upper surface of the support beam 2, and is connected to and drives the driven gear 501 via gear meshing. There are two movable cutting platforms 6, which are slidably connected to the front and rear sides of the support beam 2, respectively. The two ends of the inlet pressure roller 7 are rotatably connected to the right side of the lifting end platform 3 on both sides via bearings. There are two side flattening frames 8, which are fixedly connected to the lower right side of the two lifting end platforms 3, and are located on the lower surface of the two spiral side push shafts 701.

[0042] Furthermore, according to embodiments of the present invention, such as Figure 8 As shown, a rubber protective layer is provided on the outer surface of the middle section of the outlet pressure roller 4. The outlet pressure roller 4 includes: an anti-slip roller end 401 fixedly connected to both ends of the outlet pressure roller 4, and the surface of the anti-slip roller end 401 is provided with anti-slip ridges; the rubber protective layer plays an anti-slip role. When the material moves, the outlet pressure roller 4 is driven to rotate by friction, and the anti-slip roller end 401 further presses the cutting waste at the edge of the material and presses the cut waste to avoid the situation where the material at the cutting position is not positioned and deformed due to the cutting edge material falling off. The material is fixed after cutting, which further improves the cutting accuracy.

[0043] Furthermore, according to embodiments of the present invention, such as Figure 7 As shown, the outer surface of the middle section of the imported pressure roller 7 is provided with a rubber protective layer. Two spiral side push shafts 701 are provided, fixedly connected to the front and rear ends of the imported pressure roller 7 respectively. The front spiral side push shaft 701 is left-handed, and the rear spiral side push shaft 701 is right-handed. The spiral groove cross-section of the spiral side push shaft 701 is a semi-circular structure. Five flattening wheels 801 are rotatably connected to the side flattening frame 8. Seven wheel driven protrusions 8011 are distributed on the wheel body of the flattening wheel 801. The wheel driven protrusions 8011 are semi-circular protrusions, with the upper wheel driven protrusion 8011 located within the spiral groove of the spiral side push shaft 701. When the existing edge-cutting conveyor 1 moves, driving the material to the left, the upper surface of the material contacts the rubber coating of the imported pressure roller 7, and the friction drives the imported pressure roller 7 to rotate. The imported pressure roller 7 not only presses the material but also drives the two... The side spiral push shaft 701 rotates. When the spiral push shaft 701 rotates, the wheel driven protrusions 8011 on the front and rear flattening wheels 801 engage with the spiral grooves of the two side spiral push shafts 701. The rotation of the spiral push shaft 701 drives the wheel driven protrusions 8011 to move, causing the flattening wheels 801 to rotate. Since the front spiral push shaft 701 is left-handed, when the spiral push shaft 701 rotates clockwise, it can drive the upper wheel. The driven protrusion 8011 moves backward, causing the flattening wheel 801 to rotate. The driven protrusion 8011 on the wheel body below the flattening wheel 801 pushes forward, thus flattening the front edge of the material. Similarly, the rear spiral push shaft 701 rotates clockwise. In the same way, it can drive the rear flattening wheel 801 to rotate, and cause the driven protrusion 8011 on the wheel body of the rear flattening wheel 801 to push the edge of the material backward, thus flattening the material.

[0044] In another embodiment, such as Figure 6As shown, two guide holes 301 are provided on the surface of the lifting end platform 3. The support guard plate 302 is fixedly connected to the right end of the lifting end platform 3, and guard plates are provided on both the left and right sides of the support guard plate 302. The guide holes 301 are movably sleeved on the guide column 201. The guide column 201 guides the lifting end platform 3, and the tension spring 2011 pulls the lifting end platform 3 downward, so that the outlet pressure roller 4 and the inlet pressure roller 7 connected to it have a certain clamping force on the processed material, thereby increasing the clamping force of the outlet pressure roller 4 and the inlet pressure roller 7 on the material, thus better clamping and flattening the material.

[0045] The specific usage and function of this embodiment: In this invention, the material is unfolded and laid flat on the edge-cutting conveyor table 1, and the material is wound up on the left side by the take-up roller. When the edge-cutting conveyor table 1 is activated and the material is moved to the left, the upper surface of the material contacts the rubber coating of the inlet pressure roller 7, and the inlet pressure roller 7 is rotated by friction. The inlet pressure roller 7 not only presses the material, but also drives the two spiral side push shafts 701 to rotate. When the spiral side push shafts 701 rotate clockwise, they can drive the two flattening wheels 801 to rotate, and drive the wheel driven protrusions 8011 below the two flattening wheels 801 to push outward, realizing the pushing and spreading of the material edge; the driven component controls the driven... Driven by gear 501, when the spacing adjustment shaft 5 rotates, the screw transmission effect of adjusting thread 502 and adjusting screw hole 6012 can simultaneously drive the movable cutting platforms 6 on both sides to move towards the middle or towards both sides, thus better controlling the position of the movable cutting platforms 6 and facilitating the adjustment of the cutting edge size according to production needs. When the material moves, the exit pressure roller 4 is driven to rotate by friction, and the anti-slip roller end 401 further presses the cutting waste at the edge of the material, preventing the cutting edge material from falling off and causing the material at the cutting position to be deformed due to lack of positioning. The setting of fixing the material after cutting further improves the cutting accuracy.

[0046] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.

[0047] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
