Description
Technical Field
[0001] This utility model relates to the technical field of kraft paper processing equipment, and in particular to a coated kraft paper processing equipment with a fixed-point limiting structure. Background Technology
[0002] The processing of coated kraft paper includes key steps such as coating, drying, lamination, and cutting. Among them, the cutting device can perform high-precision and high-efficiency cutting operations on coated kraft paper. As a composite material that combines the strength of paper base and the function of film, coated kraft paper is widely used in food packaging, industrial dust protection, logistics cushioning, electronic product lining and other scenarios due to its excellent waterproof and moisture-proof properties, tear resistance and environmentally friendly recyclable characteristics.
[0003] In the field of coated kraft paper processing, traditional cutting devices mostly use manual measurement and positioning to control the cutting position. In existing technology, the device usually controls the precision by manually adjusting the position of the moving frame and marking the cutting point with a ruler. This relies on the operator's experience. In batch processing scenarios, such devices lack precise fixed-point limiting mechanisms and require repeated calibration of the cutting position, resulting in low production efficiency. Especially in scenarios that require multi-segment equidistant cutting, the accumulation of manual measurement errors will significantly reduce the finished product qualification rate, and frequent adjustments will easily cause equipment wear and tear, affecting the service life of the equipment.
[0004] Therefore, when used in scenarios requiring multi-segment equidistant cutting, it is inconvenient to ensure accurate cutting positions. Therefore, a coated kraft paper processing device with a fixed-point limiting structure can be designed. When using this device, the translation mechanism is activated to drive the moving frame to move smoothly laterally along the support platform. The positioning rod slides into contact with the inclined surface of the trapezoidal block on the outer wall of the moving frame. At this time, the positioning mechanism undergoes a contraction deformation. After the positioning rod is fully embedded in the positioning hole, the positioning mechanism pushes the positioning rod back to its original position, achieving fixed-point limiting of the moving frame. Simultaneously, the operator closes the translation mechanism, stopping the moving frame. When the cutting blade and the positioning rod are on the same vertical plane, this position is the first cutting position. The lifting mechanism is activated to drive the cutting blade to descend vertically, thereby accurately cutting the kraft paper. After the first cut is completed, the cutting blade is driven to rise and reset. The positioning rod is manually pulled out to release the limit and continue to drive the moving frame to move. When the positioning rod is embedded in the second set of positioning holes, it is positioned again for the second cut. This device achieves precise positioning and limit by cooperating with the positioning rod and the positioning hole inside the trapezoidal block. Combined with the vertical and coplanar design of the cutting blade and the positioning rod, it ensures that the cutting position is accurate and avoids manual measurement errors, thus improving cutting accuracy.

After the positioning rod is fully embedded in the positioning hole, the positioning mechanism pushes the positioning rod to reset, realizing the fixed-point limiting of the moving frame. At the same time, the operator closes the translation mechanism and stops the moving frame from moving. At this time, since the cutting blade and the positioning rod are on the same vertical plane, this position is the first cutting position.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 3 and Figure 4 This utility model provides an embodiment: a coating kraft paper processing device with a fixed-point limiting structure, including a support platform 1 and a laterally movable frame 2. The movable frame 2 is slidably disposed on the upper surface of the support platform 1. Two sets of trapezoidal blocks 3 are fixedly disposed on one side of the outer wall of the movable frame 2. A cutting blade 4 and a positioning rod 5 are disposed on the top side of the support platform 1. A positioning hole 6 adapted to the positioning rod 5 is opened in the middle part of each set of trapezoidal blocks 3. A cutting mechanism and a positioning mechanism are disposed on the top side of the support platform 1. A translation mechanism is disposed between the bottom of the movable frame 2 and the top of the support platform 1. A fixing mechanism is disposed in the inner cavity of the movable frame 2.
[0025] Please see Figure 3 and Figure 4 The inner wall of the movable frame 2 has two sets of cutting grooves 7. Two sets of trapezoidal blocks 3 are respectively set one-to-one with the two sets of cutting grooves 7. The two sets of trapezoidal blocks 3 and the two sets of cutting grooves 7 are arranged in a horizontally equidistant array. The cutting blade 4 and the positioning rod 5 are on the same vertical plane. The two sets of cutting grooves 7 on the bottom wall of the movable frame 2 correspond one-to-one with the two sets of trapezoidal blocks 3. The cutting blade 4 is driven to descend vertically and accurately cut the kraft paper through the cutting grooves 7. The cutting mechanism includes a support column 8, a top plate 9, an electrically controlled lifting cylinder 10 and a lifting seat 11. The top side of the support platform 1 Multiple sets of support columns 8 are fixedly installed, arranged in a rectangular array and symmetrically positioned on both sides of the movable frame 2. A top plate 9 is fixedly installed on the top of the multiple sets of support columns 8, and an electrically controlled lifting cylinder 10 is fixedly installed in the middle of the top plate 9. A lifting seat 11 is fixedly installed at the telescopic end of the electrically controlled lifting cylinder 10. The two sides of the lifting seat 11 are slidably fitted onto the side walls of the multiple sets of support columns 8. The top surface of the cutting blade 4 is fixedly connected to the bottom surface of the lifting seat 11. When the electrically controlled lifting cylinder 10 is activated, it pushes the lifting seat 11 down along the multiple sets of support columns 8, causing the cutting blade 4 to descend vertically and precisely cut the kraft paper through the cutting groove 7.
[0026] Please see Figure 3 and Figure 4 The positioning mechanism includes a fixed shell 12, a limiting plate 13, and a return spring 14. The fixed shell 12 is fixedly installed on one side of the top of the support platform 1. The limiting plate 13 is fixedly installed on the side wall of the positioning rod 5. The limiting plate 13 is located in the inner cavity of the fixed shell 12. The return spring 14 is fixedly installed between the side wall of the limiting plate 13 and the inner wall of the fixed shell 12. When the positioning rod 5 slides into the positioning hole 6 in the middle of the trapezoidal block 3, the return spring 14 is compressed and deformed due to the pressure of the limiting plate 13. After the positioning rod 5 is fully embedded in the positioning hole 6, the return spring 14 pushes the limiting plate 13 and the positioning rod 5 to return to their original positions, thereby achieving the fixed-point positioning of the moving frame 2. The positioning mechanism also includes a sliding bead 15. The positioning rod 5 passes through and slides inside the fixed shell 12. The inner end of the positioning rod 5 is rotatably provided with a sliding bead 15. The sliding bead 15 is slidably connected to one side of the outer wall of the moving frame 2. During the movement, the sliding bead 15 at the inner end of the positioning rod 5 slides in contact with the inclined surface of the trapezoidal block 3 on the outer wall of the moving frame 2.
[0027] Please see Figure 1 and Figure 2The translation mechanism includes a translation slide 16 and a translation slide base 17. The translation slide 16 is fixedly installed at the top middle part of the support platform 1. The output end of the translation slide 16 is connected to two sets of translation slide bases 17. The two sets of translation slide bases 17 are fixedly connected to the bottom sides of the moving frame 2 respectively. When the translation slide 16 is activated, it drives the two sets of translation slide bases 17, causing the moving frame 2 to move smoothly laterally along the support platform 1. The fixing mechanism includes a clamping plate 18 and an electrically controlled telescopic rod 19. The clamping plates 18 are respectively installed on both sides of the inner cavity of the moving frame 2. The electrically controlled telescopic rod 19 is fixedly installed on the other side of the outer wall of the moving frame 2. The telescopic end of the electrically controlled telescopic rod 19 is fixedly connected to the inner wall of the clamping plate 18 on the same side. The clamping plate 18 on the other side is fixedly connected to the inner wall of the inner cavity of the moving frame 2. When the electrically controlled telescopic rod 19 is activated, it pushes the clamping plate 18, so that the kraft paper is clamped and fixed by the other fixed clamping plate 18.
[0028] When using this coated kraft paper processing device with a fixed-point limiting structure, the working principle of the device is as follows: During operation, firstly, multiple coated kraft papers of the same size are stacked into the inner cavity of the moving frame 2. Then, the electrically controlled telescopic rod 19 is activated to push the clamping plate 18, so that the kraft paper is clamped and fixed by another fixed clamping plate 18.
[0029] Then, the translation slide 16 is activated to drive the two sets of translation slide blocks 17, which in turn drive the moving frame 2 to move smoothly laterally along the support platform 1. During the movement, the sliding ball 15 at the inner end of the positioning rod 5 slides into contact with the inclined surface of the trapezoidal block 3 on the outer wall of the moving frame 2. When the sliding ball 15 slides into the positioning hole 6 in the middle of the trapezoidal block 3, the return spring 14 is compressed and deformed due to the pressure of the limiting plate 13. After the sliding ball 15 is fully embedded in the positioning hole 6, the return spring 14 pushes the limiting plate 13 and the positioning rod 5 to reset, thereby achieving the fixed-point limit of the moving frame 2. At the same time, the operator closes the translation slide 16 and stops the movement of the moving frame 2.
[0030] At this time, since the cutting blade 4 and the positioning rod 5 are on the same vertical plane, and the two sets of cutting grooves 7 on the bottom wall of the moving frame 2 correspond one-to-one with the positions of the two sets of trapezoidal blocks 3, this position is the first cutting position. The electric lifting cylinder 10 is started to push the lifting seat 11 down along the multiple sets of support columns 8, which drives the cutting blade 4 to descend vertically and accurately cut the kraft paper through the cutting groove 7.
[0031] After the first cut is completed, the electric lifting cylinder 10 drives the cutting blade 4 to rise and reset. The positioning rod 5 is manually pulled out to release the limit. The translation slide 16 is started to drive the moving frame 2 to move. When the sliding ball 15 is embedded in the second set of positioning holes 6, it is positioned again and the second cut is performed. After the cut is completed, the cutting blade 4 rises and resets. The translation mechanism drives the moving frame 2 to move out of the cutting area, and the staff takes out the finished product.
[0032] The device achieves precise positioning and limiting by cooperating the positioning rod 5 with the positioning hole 6 inside the trapezoidal block 3. Combined with the vertical and coplanar design of the cutting blade 4 and the positioning rod 5, it ensures that the cutting position is accurate and avoids manual measurement errors, thereby improving cutting accuracy.
[0033] The device uses the elastic positioning mechanism of the return spring 14 and the sliding ball 15 to quickly complete the positioning and locking, and also facilitates manual release of the limit for continuous cutting, making it convenient and efficient to operate.
[0034] The two-stage cutting process, combined with the step-by-step positioning function of the positioning mechanism, enables continuous and precise cutting of multiple sheets of kraft paper, greatly improving processing efficiency. The overall device has a compact structure, and the various mechanisms work together to ensure cutting quality and improve production efficiency, making it suitable for large-scale industrial processing of coated kraft paper.
[0035] Through the above steps, when using this coated kraft paper processing device with a fixed-point limiting structure, the translation mechanism is activated to drive the moving frame 2 to move smoothly laterally along the support platform 1. The positioning rod 5 slides into contact with the inclined surface of the trapezoidal block 3 on the outer wall of the moving frame 2. At this time, the positioning mechanism undergoes a contraction deformation. After the positioning rod 5 is fully embedded in the positioning hole 6, the positioning mechanism pushes the positioning rod 5 to reset, realizing the fixed-point limiting of the moving frame 2. At the same time, the operator closes the translation mechanism and stops the movement of the moving frame 2. At this time, since the cutting blade 4 and the positioning rod 5 are on the same vertical plane, this position is the first... At the cutting position, the lifting mechanism is activated to drive the cutting blade 4 to descend vertically, thereby accurately cutting the kraft paper. After the first cut is completed, the cutting blade 4 is driven to rise and reset. The positioning rod 5 is manually pulled out to release the limit, and the moving frame 2 continues to move. When the positioning rod 5 is embedded in the second set of positioning holes 6, it is positioned again for the second cut. This device achieves precise positioning and limit through the cooperation of the positioning rod 5 and the positioning hole 6 inside the trapezoidal block 3. Combined with the vertical and coplanar design of the cutting blade 4 and the positioning rod 5, it ensures that the cutting position is accurate and avoids manual measurement errors, thereby improving the cutting accuracy.
[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
