Description

Technical Field

[0001] The invention relates to the technical field of slitting, and more specifically to an automatic controlled slitting device for feeding wet wipes. Background Art

When the incoming wet wipes cannot meet the size requirements, the incoming wet wipes need to be cut. The cutters of existing cutting equipment are mostly fixed.

In view of this, we propose an automatic control cutting device for wet wipes feeding. Summary of the invention

[0011] Preferably, a plurality of fixing frames are slidably connected to the rack, and tooth tips are fixedly mounted on the support plate, and the tooth tips are inserted into tooth grooves of the rack for limiting position.

[0012] Preferably, it further comprises a lifting assembly, wherein the lifting assembly comprises a first hydraulic cylinder and a lifting frame, wherein the first hydraulic cylinder is fixedly mounted on the supporting assembly, and sliders are fixedly mounted at both ends of the lifting frame, the sliders are slidably connected to the supporting assembly, and the output shaft of the first hydraulic cylinder is fixedly connected to the corresponding slider;

[0013] Both ends of the adjusting column are fixedly mounted on the corresponding sliding blocks, and the fixing column is fixedly mounted on the supporting assembly.

[0014] Preferably, the slitting assembly includes a guide sleeve, the top of which is fixedly mounted on the bottom of the sleeve, an extension column is slidably connected inside the guide sleeve, a second hydraulic cylinder is fixedly mounted on the guide sleeve, an output shaft of the second hydraulic cylinder is fixedly connected to the extension column, a positioning hole is provided on the extension column, a knife seat is plugged into the positioning hole, a cutting knife is fixedly mounted on the bottom of the knife seat, and the knife seat and the extension column are fixed by a limit pin.

[0015] Preferably, a limit block is fixedly installed on one side of the support plate close to the sleeve, a detection plate is fixedly installed on the limit block, and a detection surface of each detection plate is coplanar with a cutting line of a corresponding cutter;

[0016] A laser displacement sensor is fixedly mounted on the support assembly and is used to detect the distance between the laser displacement sensor and the detection plate. The position of the laser displacement sensor corresponds to the position of the detection plate.

[0017] Preferably, the distance between the two cutting knives is equal to the difference between the displacement values ​​of the two corresponding detection plates detected by the laser displacement sensor.

[0018] By adopting the above scheme, the distance detection of the detection plate is carried out by the laser displacement sensor, so that the position of the cutter can be measured, and the distance between the two cutters can be obtained by subtracting the displacement of two adjacent detection plates, thereby determining the cutting width of the wet wipes raw material.

[0021] By adopting the above scheme, the extension amounts of several telescopic cylinders are kept the same, and the extension amounts of the telescopic cylinders can be controlled by setting an initial threshold value. The output shaft of the first hydraulic cylinder drives the lifting frame, the slider, the adjustment column and several adjustment blocks to rise or fall. The cutter spacing is raised when it is adjusted to a smaller size, and lowered when it is adjusted to a larger size. The adjustment block drives the angle of the telescopic rod and the telescopic cylinder to change. At the same time, under the action of the first elastic member, several adjustment blocks will move to the right as a whole. It should be noted that the height of the rise or fall of the adjustment block is preset according to the cutter spacing to be adjusted.

[0022] After the height adjustment is completed, the position of the detection plate corresponding to the first adjustment block is detected by the laser displacement sensor to determine the relative position of the corresponding cutter and the edge of the wet wipes raw material. The output end of the moving component drives the first adjustment block to move, so that the corresponding cutter moves to the set position of the edge of the wet wipes raw material. The corresponding electromagnet is energized, the armature moves toward the electromagnet and is fixed, and the tooth tip is inserted into the tooth groove of the rack for limiting.

[0023] After the cutter corresponding to the first adjustment block is fixed, the detection plate corresponding to the first adjustment block is out of the laser detection area, and the second adjustment block can be detected by the laser displacement sensor. By adjusting the extension or contraction of the telescopic cylinder corresponding to the second adjustment block, the cutter and the detection plate corresponding to the second adjustment block are controlled to move. The slitting width of the wet wipes raw material is equal to the difference between the detection spacing displacement value of the second cutter and the detection displacement value of the first cutter, thereby determining the position of the second cutter;

[0024] After the position of the second cutter is determined, the corresponding electromagnet is energized, and the corresponding tooth tip is inserted into the tooth groove of the rack to fix the position of the second cutter. The above operation can be repeated to adjust the spacing of multiple sets of cutters. The output shaft of the second hydraulic cylinder pushes the cutter on the extension column down to the set cutting height to perform the cutting operation on the raw material.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. The lifting assembly of the present invention drives the adjustment column and the adjustment block to rise and fall, and then drives the telescopic cylinder and the telescopic rod to rotate, controls the sleeve to slide on the fixed column, and adjusts the cutting spacing of the cutter installed under the sleeve by controlling the extension and retraction of the output shaft of the telescopic cylinder and cooperating with the magnetic attraction fixation of the sleeve by the limit assembly, so as to realize the adjustment of the variable cutting spacing, thereby meeting the cutting of wet wipes raw materials of different sizes, has strong flexibility and the knife setting process can be automatically controlled without manual operation.

[0027] 2. The present invention can measure the position of the cutter by detecting the distance of the detection plate through the laser displacement sensor, and the distance between the two cutters can be obtained by subtracting the measured values ​​of two adjacent detection plates, thereby determining the cutting width of the wet wipes raw material.

[0028] 3. The present invention, through the setting of the moving component, can control the first cutter to move along the axial direction of the fixed column after the height adjustment of the adjustment block is completed, so as to adapt to the edge or edge trimming of the wet wipes raw material, and further improve the flexibility of cutting.

[0029] 4. In the present invention, after the position of a cutter is relatively determined, the corresponding electromagnet is energized, and the armature moves toward the electromagnet and is fixed under the magnetic attraction force, and the tooth tip is inserted into the tooth groove of the rack, which effectively improves the stability of the fixed position of the cutter. At the same time, when the armature moves, it will drive the support plate and the detection plate to move synchronously. The detection plate is out of the detection area of ​​the laser displacement sensor, and the laser displacement sensor cannot detect the detection plate, while the next detection plate can be detected, thereby realizing the measurement and determination of the next cutter position.

[0030] 5. When the plurality of groups of cutters of the present invention are aligning the cutter lines, the cutter closest to the cutter lines can be selected through sensors, thereby realizing a rapid cutter alignment process and improving the cutter alignment efficiency.

When the output shaft of the telescopic cylinder 32 is extended or contracted, the sleeve 42 can be further controlled to move, so as to realize the variable spacing control between the plurality of sleeves 42 and improve the flexibility of spacing adjustment.

[0044] Reference Figures 1 to 3 The slitting device also includes a limit assembly 5, which includes a rack 51 and a plurality of support plates 52. The rack 51 is fixedly mounted on the support frame 11, and the rack 51 is arranged parallel to the fixed column 41. A guide rail 53 is fixedly mounted on the rack 51, and a plurality of fixed frames 54 are slidably connected to the guide rail 53. The support plate 52 is slidably connected to a plurality of guide rods 55, one end of the guide rod 55 is fixedly connected to the fixed frame 54, and the other end is fixedly connected to the sleeve 42. A second elastic member 56 is sleeved on the guide rod 55. The second elastic member 56 is sleeved on the guide rod 55. One end of the elastic member 56 is fixedly connected to the support plate 52, and the other end is fixedly connected to the sleeve 42. An electromagnet 57 is fixedly installed on the fixed frame 54. An armature 58 and a tooth tip 59 are fixedly installed on the side of the support plate 52 close to the electromagnet 57. The second elastic member 56 is used to pull the support plate 52 to move toward the sleeve 42 to ensure that the tooth tip 59 can be normally separated from the tooth groove of the rack 51. A limit block 510 is fixedly installed on the side of the support plate 52 close to the sleeve 42, and a detection plate 511 is fixedly installed on the limit block 510.

[0045] Reference Figure 2 , Figure 4 and Figure 5 A plurality of slitting components 6 are installed below the sleeve 42. The slitting components 6 include a guide sleeve 61. The top of the guide sleeve 61 is fixedly installed on the bottom of the sleeve 42. An extension column 62 is slidably connected in the guide sleeve 61. A second hydraulic cylinder 63 is fixedly installed on the guide sleeve 61. The output shaft of the second hydraulic cylinder 63 is fixedly connected to the extension column 62. A positioning hole 64 is provided on the extension column 62. A knife seat 65 is inserted and matched in the positioning hole 64. A cutter 66 is fixedly installed at the bottom of the knife seat 65. The cutter 66 is located above the support roller 13. A first limiting hole 67 is provided on the extension column 62. A second limiting hole 68 is provided on the knife seat 65. After the knife seat 65 is inserted into the positioning hole 64, the axes of the first limiting hole 67 and the second limiting hole 68 are collinear. The limiting pin is inserted into the first limiting hole 67 and the second limiting hole 68 to fix the knife seat 65 on the extension column 62. The output shaft of the second hydraulic cylinder 63 can push the cutter 66 on the extension column 62 to rise or fall, thereby realizing the height control of the cutter 66 at the working position. The knife holder 65 is fixed to the extension column 62 by the limit pin. When the cutter 66 is replaced, the knife holder 65 and the cutter 66 can be quickly disassembled at the same time, thereby reducing the difficulty of disassembly and assembly of the cutter 66.

[0046] Reference Figure 1 and Figure 6, a laser displacement sensor 7 is fixedly mounted on the guide frame 12, which is used to detect the distance with the detection plate 511. The position of the laser displacement sensor 7 corresponds to the position of the detection plate 511. The detection surface of each detection plate 511 is coplanar with the cutting line of the corresponding cutter 66. Therefore, by detecting the distance of the detection plate 511 through the laser displacement sensor 7, the position of the cutter 66 can be measured, and the distance between the two cutters 66 can be obtained by subtracting the displacement of two adjacent detection plates 511, thereby determining the slitting width of the wet wipes raw material. It should be noted that when the electromagnet 57 is energized, the armature 58 is fixed on the electromagnet 57, and the detection plate 511 moves synchronously with the support plate 52. The laser detection line of the laser displacement sensor 7 cannot detect the detection plate 511. At this time, the detection plate 511 is out of the detection area of ​​the laser displacement sensor 7.

[0047] Reference Figure 7 The slitting device further includes a moving assembly 8, which includes a mounting frame 81, which is fixedly mounted on the lifting frame 22, on which a driving motor 82 is fixedly mounted, and an output shaft of the driving motor 82 is fixedly connected with a screw rod 83, which is rotatably connected to the mounting frame 81, and a moving frame 84 is threadedly matched on the screw rod 83, which is slidably connected to the mounting frame 81, and an adjustment block 34 closest to the laser displacement sensor 7 is fixedly mounted on the bottom of the moving frame 84. It should be noted that the moving assembly 8 can also be a component with adjustable displacement such as an electric slide.

[0048] Working principle: For the convenience of description, according to Figure 2 The adjustment blocks 34 are sequentially recorded as the first, second to Nth from right to left in the figure. The extension amounts of the telescopic cylinders 32 remain the same, and the extension amounts of the telescopic cylinders 32 can be controlled by setting an initial threshold. The output shaft of the first hydraulic cylinder 21 drives the lifting frame 22, the slider 23, the adjustment column 31 and the several adjustment blocks 34 to rise or fall. The spacing of the cutters 66 rises when the spacing is adjusted to a smaller size, and falls when the spacing is adjusted to a larger size. The adjustment blocks 34 drive the angles of the telescopic rods 33 and the telescopic cylinders 32 to change. At the same time, under the action of the first elastic member 35, the several adjustment blocks 34 will move to the right as a whole. It should be noted that the height to which the adjustment blocks 34 rise or fall is preset according to the spacing of the cutters 66 to be adjusted.

[0049] After the height adjustment is completed, the position of the detection plate 511 corresponding to the first adjustment block 34 is detected by the laser displacement sensor 7 to determine the relative position of the corresponding cutter 66 and the edge of the wet wipes raw material. The output end of the moving component 8 drives the first adjustment block 34 to move, so that the corresponding cutter 66 moves to the set position of the edge of the wet wipes raw material, the corresponding electromagnet 57 is energized, the armature 58 moves toward the electromagnet 57 and is fixed, and the tooth tip 59 is inserted into the tooth groove of the rack 51 to limit the position.

[0050] After the cutter 66 corresponding to the first adjustment block 34 is fixed, the detection plate 511 corresponding to the first adjustment block 34 is out of the laser detection area, and the second adjustment block 34 can be detected by the laser displacement sensor 7. By adjusting the extension or contraction of the telescopic cylinder 32 corresponding to the second adjustment block 34, the cutter 66 and the detection plate 511 corresponding to the second adjustment block 34 are controlled to move. The cutting width of the wet wipes raw material is equal to the difference between the detection spacing displacement value of the second cutter 66 and the detection displacement value of the first cutter 66, thereby determining the position of the second cutter 66.

[0051] After the position of the second cutter 66 is determined, the corresponding electromagnet 57 is energized, and the corresponding tooth tip 59 is inserted into the tooth groove of the rack 51 to fix the position of the second cutter 66. The above operation can be repeated to adjust the spacing of multiple groups of cutters 66. The output shaft of the second hydraulic cylinder 63 pushes the cutter 66 on the extension column 62 down to the set cutting height to perform the cutting operation on the raw material.

[0052] The slitting device of this embodiment can have different adjustment modes according to different numbers of cutting lines. When there is only one cutting line for the wet wipes raw material and a plurality of sleeves 42 are raised and lowered, the laser displacement sensor 7 measures the positions of a plurality of detection plates 511 from right to left until the detection plate 511 closest to the cutting line of the wet wipes raw material is determined. If the cutting line is on the left side of the nearest detection plate 511, the electromagnets 57 corresponding to the plurality of detection plates 511 on the right side of the detection plate 511 are energized, and the armature 58 is magnetically attracted, thereby fixing the sleeve 42 on the right side, and the output shaft of the telescopic cylinder 32 corresponding to the detection plate 511 closest to the cutting line and the detection plate 511 on its left side is contracted, thereby quickly positioning the cutting line.

[0053] When there are two cutting lines of the wet wipes material, the first cutter 66 is positioned and fixed by the moving assembly 8 in cooperation with the laser displacement sensor 7, and the second cutting line of the wet wipes material is detected by the laser displacement sensor 7 to determine the detection plate 511 closest to the cutting line, thereby improving the cutter 66 alignment efficiency. When there are multiple cutting lines of the wet wipes material, fast cutter alignment can be achieved according to the above principle of selecting the closest cutter 66.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
