Description

Description: A numerically controlled longitudinal slitting device for a packaging machine

[0001] The patent relates to a numerical control slitting knife device of a packaging machine, which is mainly used for packaging materials on an automatic production line.

(eg syringes, needles, infusion sets, surgical kits, medicines, food, etc.) for packaging and slitting.

Background technique

[0002] The working principle of the existing packaging machine: The bottom film (plastic film) on the machine is clamped into the machine by the clip chain on both sides; the drive of the machine causes the clip chain to bring the bottom film of the package every single mode distance. Forming area, under the action of the mold, the packaging base film is formed into a plurality of cavities suitable for discharging materials by heating and blistering; the packaging bottom film enters the discharge area, and the material is placed into the cavity of the packaging bottom film by manual or auxiliary machine. The cover film (or paper) enters the machine and covers the mouth surface of the cavity, and enters the sealing area together; the sealing film (or paper) is sealed with the cavity film containing the material by using a sealing mechanism. Continuous product, packaged; enters the cutting zone and cuts the continuous product into easy-to-use monomers. Cross-cutting and slitting; the cross-cut is perpendicular to the direction of product movement, cutting the package, leaving the clip-clamped part to move integrally; the slit is parallel to the direction of product movement, and the individual in each lateral direction is cut into individual , and cut off the clamped part (waste side); the finished product after the packaging is output from the discharge port, thereby completing the entire work of the packaging machine production line

[0003] The number of installations and position adjustments of the slitting knives of the existing packaging machine are all installed, adjusted, and trial-produced by a master with operational experience, and all of them can be produced after being in place. Adjust the coarse adjustment, fine adjustment, trial operation, etc., all of which can meet the requirements before they can work normally. When the variety is changed, the above adjustments are repeated because the number of different single-mode laterals of the mold is different. The adjustment work is complicated and cumbersome, and it is necessary to waste more packaging materials, energy consumption and daytime, etc., and the requirements for the quality of the adjustment personnel are also high.

Embodiments of the invention [0036] Referring to FIG. 1 to FIG. 8, the longitudinal cutting floating hob of the numerical control slitting knife device of the packaging machine 2: according to the number and size of the transverse cavity of the packaging mold of the packaging machine, the longitudinal cutting floating hob 2 is mounted to On the frame 1 (the number is one more than the single-mode lateral cavity, the position is determined according to the size of the mold), the cut product 3 passes between the slitting drum 4 and the slitting floating hob 2, and the product 3 moves in the direction As indicated by the arrows in Figure 1. The pressure gas is introduced from the intake valve 26 to generate air pressure in the floating cylinder 6 in the cutter box 24, to move the piston 25 of the floating cylinder 6, to move the cutter fork 23, and to float the roller blade 21 through the hob shaft 22. The roller blade 21 bears against the slit product 3 and the slitting drum 4 under a certain pressure. The working longitudinal slitting drum 4 and the slitted product 3 are rotated at the same speed by the machine control, and the rolling blade 21 is passively rotated to cut the product 3 under the blade edge and the floating pressure, thereby completing the slitting work. In the non-CNC condition, after replacing the packaging materials and the mold, the vertical cutting floating hob 2 is installed and adjusted by a professional with debugging experience. Remove the excess or add the insufficient longitudinal floating hob 2, and then Adjust, test, re-adjust, and try again until it is accurate before normal production.

[0037] The numerically controlled slitting cutter device of the present embodiment takes eleven longitudinally-cut floating hobs 2 as an example (full working 吋 can cut the product _{3 of the} single-mode 10 transverse cavities, see FIG. 2, the slitting and rolling The knife 2 and the matching floating cylinder 6 and the cylinder supporting slide rod 5, the hob sliding rod 10, etc. are mounted and fixed on the frame 1 according to Figs. 3 and 6, and the mechanism driving portion is mounted according to Fig. 5. The crucible is in a non-working state. The moving block 7 retracts all 11 slitting floating hobs 2 to the initial position. Referring to Fig. 3, the position data of each slitting floating hob 2 is recorded in the control system 12 of the machine. When the work command is issued, the computer The parameters are input into the single-mode lateral cavity number and the slitting size. The computer automatically assigns the vertical-cutting floating hob 2 and finds each position. The motor 11 and the connected screw 8 drive the moving block 7, and the corresponding longitudinal-cut floating roller The knife 2 and its floating cylinder 6 are moved laterally into position.

[0038] This example illustrates the working process of the patent by taking a single mode 6 lateral cavities as an example: The control system 12 automatically allocates the number of slitting reeds 2 to seven and specifies the left number 1, 3, 5, 7, 9, 10, 11 longitudinal slitting hob 2 work, the same computer output seven vertical cutting floating hob 2 working position. Each of the floating cylinders 6 of the longitudinal slitting reel 2 is pushed out of the piston 25 to erect the longitudinally floating reel 2 (Fig. 4), and the moving block 7 is moved to the initial position of the No. 1 slitting reel 2 Below, the floating cylinder 6 of the No. 1 slitting floating hob 2 retracts the piston 25, and the No. 1 slitting floating hob 2 lays down, and the knife box 24 is embedded in the slitting floating hob mounting groove of the moving block 7, and the moving block 7 is moved. The No. 1 slitting floating hob 2 is brought into the working position, and when it is in position, the piston 25 is pushed out to raise it. The moving block 7 is returned to the lower side of the No. 3 slitting floating hob 2, and is also fed to the working position. The No. 2 slitting floating hob 2 also follows the initial position of the No. 3 slitting floating hob 2. And located on the left side of the No. 3 slitting floating hob 2; Similarly, the 5, 7, 9, 10, 11 longitudinal slitting hobs 2 will be moved into position, see Figure 7. After all the longitudinal cutting floating hobs 2 are in place, the floating cylinders 6 corresponding to the non-working slitting floating hobs 2 are retracted, and the 2, 4, 6 and 8 longitudinal slitting reels 2 are smashed to avoid interference with the package. by. After the intake valve 26 of the slitting floating hob 2 to be operated is smashed, the machine can enter the normal production state. After the work is completed or the package type needs to be replaced, as long as the moving block 7 is moved below the working position of the No. 1 slitting floating hob 2, the slitting floating hob 2 is lowered, and the knife box 24 is embedded in the longitudinal floating of the moving block 7. In the hob mounting groove, all the longitudinal floating hobs 2 are collectively taken into the initial position, waiting for the next batch of work.

The patent is improved on the basis of the existing slitting cutter device, so that the number and specific positioning of the slitting floating hob 2 are intelligent, and the structure is simple, reliable and convenient. Equivalent or simple changes made in the construction, features and principles of this patent will fall within the protection scope of this patent.
