[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] Example:
[0023] Reference Figures 1-3 This application discloses a packaging tape cutting device, including a worktable 1. The worktable 1 is adjustablely equipped with a clamping component for transport packaging tape. The clamping component includes a clamping frame 3, a fixed roller 4, and a clamping roller 5. The clamping frame 3 is adjustablely slidably mounted on the worktable 1. The clamping frame 3 can be driven by a motor and a screw, and is threaded onto the screw. This driving method is a common prior art and will not be described in detail here. Adjusting the clamping frame 3 can facilitate the cutting of packaging bags of different lengths. The fixed roller 4 is rotatably mounted on the clamping frame 3. The clamping frame 3 is equipped with a clamping cylinder 6 with a vertically downward telescopic end. A telescopic frame 7 is fixedly mounted on the telescopic end of the clamping cylinder 6. The clamping roller 5 is rotatably mounted on the telescopic frame 7. The clamping roller 5 is parallel to the axis of the fixed roller 4 and corresponds vertically. With this configuration, the clamping cylinder 6 drives the telescopic frame 7 and the clamping roller 5 to move towards the fixed roller 4, clamping the packaging bag between the fixed roller 4 and the clamping roller 5. The fixed roller 4 is then driven to rotate, causing the packaging bag to move.
[0024] like Figure 1 As shown, a processing frame 2 is provided on the workbench 1 and on one side of the clamping component. A cutting component for cutting packaging tape is provided on the side of the processing frame 2 facing the clamping component. The cutting component includes a processing cylinder 9, an upper cutting blade 10 and a lower cutting blade 11. The processing cylinder 9 is fixed on the processing frame 2 and its extension end is vertically downward. A processing plate 12 is fixed on the extension end of the processing cylinder 9. The upper cutting blade 10 is fixed at the bottom of the processing plate 12. The lower cutting blade 11 is fixed on the processing frame 2 and corresponds vertically to the upper cutting blade 10. The processing cylinder 9 drives the upper cutting blade 10 to move towards the lower cutting blade 11 and cuts the packaging bag that passes by. Both the upper cutting blade 10 and the lower cutting blade 11 are hot cutting blades. A conveying roller 8 is rotatably mounted on the processing frame 2, facing the clamping frame 3. The axis of the conveying roller 8 is parallel to that of the fixed roller 4. The top of the conveying roller 8 is on the same horizontal line as the top of the fixed roller 4, which facilitates the transport of the packaging bag between the upward cutting blade 10 and the downward cutting blade 11. Clamping components corresponding to the conveying roller 27 can also be set on the work frame to clamp longer packaging bags. Several guide rods 13 are also provided on the processing plate 12. The guide rods 13 slide vertically through the processing frame 2. Each guide rod 13 has a top cap at its end and a guide spring 14 is sleeved on each guide rod 13. Both ends of the guide spring 14 are fixed between the processing frame 2 and the top cap of the corresponding guide rod 13.
[0025] like Figure 1 and Figure 2 As shown, the processing frame 2 is equipped with a stabilizing component for clamping the packaging strap during cutting. The stabilizing component includes a stabilizing rod 15, a first stabilizing plate 16, a second stabilizing plate 17, two transport shafts 18, and a stabilizing block 19. The stabilizing rod 15 is vertically fixed to the bottom of the processing plate 12, the first stabilizing plate 16 is fixed to the bottom end of the stabilizing rod 15, and the second stabilizing plate 17 is located below the first stabilizing plate 16. Several buffer rods 20 are fixed on the second stabilizing plate 17. The buffer rods 20 are vertically upward and slide through the first stabilizing plate 16. Each end of the dry buffer rod 20 passing through the first stabilizing plate 16 is provided with a limiting block 21. Several buffer springs 22 are fixed between the first stabilizing plate 16 and the second stabilizing plate 17. Two transport shafts 18 are located below the second stabilizing plate 17 and are rotatably mounted on the processing frame 2. Each of the two transport shafts 18 is fitted with a pulley 23, and a transport belt 24 is fitted between the two pulleys 23. The stabilizing block 19 is fixed on the processing frame 2 and located between the two transport shafts 18, with the stabilizing block 19 corresponding to the second stabilizing plate 17 vertically. The processing cylinder 9 drives the first stabilizing plate 16 and the second stabilizing plate 17 to move towards the stabilizing block 19, and fixes the packaging bag between the second stabilizing plate 17 and the stabilizing block 19 to improve the stability during cutting. The transport shafts 18 and the transport bag facilitate the transportation of the cut packaging bag.
[0026] like Figure 1 and Figure 3As shown, a stacking assembly is provided on the workbench 1 on the side of the processing rack 2 away from the clamping member. The stacking assembly includes a stacking frame 25, a stacking plate 26, and an ejector. The stacking frame 25 is fixed on the workbench 1, and the stacking plate 26 is fixed on the stacking frame 25. The end of the stacking plate 26 away from the processing rack 2 is inclined downwards. Several transport rollers 27 are rotatably mounted on the stacking plate 26. A limiting plate 28 is hinged to the end of the stacking plate 26 away from the processing rack 2. The limiting plate 28 is fixed by a shaft and a torsion spring. The inclined stacking plate 26 and the limiting plate 28 can effectively support the cut packaging bags. The ejector is fixed on the workbench 1 and is used to eject the packaging bags on the stacking plate 26. The ejector includes a motor 29, a cam 30, an ejector plate 31, and several ejector rods 32. The motor 29 is fixed on the workbench 1, the cam 30 is fixed on the workbench 1, the cam 26 is fixed on the workbench 25, and the ejector is fixed on the workbench 1. The end of the stacking plate 26 away from the processing rack 26 is inclined downwards. Several transport rollers 27 are rotatably mounted on the stacking plate 26. The end of the stacking plate 26 away from the processing rack 26 is hinged on the workbench 1 ... A ejector plate 31 is fixed to the output end of motor 29 and located at the bottom of stacking plate 26. The ejector plate 31, facing cam 30, has a roller 33 for abutting against the outer circle of cam 30. Stacking plate 26 has several ejection holes 34, and several ejection rods 32 are fixed to the ejector plate 31 and slide through the corresponding ejection holes 34. Several abutment springs 35 are also fixed between the ejector plate 31 and stacking plate 26. Motor 29 drives cam 30 to rotate, causing ejector plate 31 and ejection rods 32 to slide out of the corresponding ejection holes 34. This facilitates the discharge of stacked packaging bags from the limiting plate 28 and can also lift packaging bags that are stuck or restricted in movement after entering stacking plate 26. When the ejection rods 32 retract, the packaging bags can move freely on stacking plate 26. The limiting plate 28 can be rotated manually or by using a cylinder. The processing rack 2 is also equipped with a detection probe to facilitate the detection of the packaging bags on the stacking rack 25.
[0027] Working principle:
[0028] First, based on the length of the packaging bag to be cut, the position of the clamping component on the workbench 1 is adjusted by the motor-driven screw. After the equipment is started, the clamping cylinder 6 pushes the telescopic frame 7 and the clamping roller 5 to move down, working together with the fixed roller 4 to clamp the packaging bag. The fixed roller 4 rotates to drive the packaging bag to the cutting station.
[0029] When the front end of the packaging bag reaches below the cutting part, the processing cylinder 9 drives the processing plate 12 to move the upper cutting blade 10 downward. At the same time, the stabilizing rod 15 of the stabilizing part pushes the first stabilizing plate 16 and the second stabilizing plate 17 to press down synchronously, so that the second stabilizing plate 17 and the lower stabilizing block 19 together clamp the cutting area of the packaging bag. At this time, the upper cutting blade 10 and the lower cutting blade 11 complete the hot cutting action. The guide rod 13 and the guide spring 14 ensure that the processing plate 12 moves smoothly.
[0030] After cutting, the processing cylinder 9 resets, and the stabilizing component rises to release the clamp. The cut packaging bags are then transported to the stacking plate 26 by the conveyor belt 24 driven by two transport shafts 18. The packaging bags slide down the inclined surface of the stacking plate 26 to the limiting plate 28 and are stacked. The transport rollers 27 on the stacking plate 26 assist in their smooth movement. When the movement of the stacked packaging bags is obstructed, the motor 29 drives the cam 30 to rotate, pushing the ejector plate 31 to move upward against the resistance of the abutment spring 35. This causes the ejector rod 32 to pass through the ejector hole 34 of the stacking plate 26 and lift the stacked packaging bags. The ejector rod 32 retracts, causing the packaging bags to fall, achieving a vibration-like effect and arranging the packaging bags in an orderly manner. When unloading is required, the stacked packaging bags can be lifted by the ejector rod 32 for easy handling, or the limiting plate 28 can be rotated to allow the stacked packaging bags to slide smoothly off the stacking plate 26 through the rotation of several transport rollers 27.
