DETAILED DESCRIPTION
[0016] The present application is further described in detail below in conjunction with the accompanying drawings.
[0017] The embodiment of the present application discloses a large-size material die-cutting stacking knife production process and die-cutting equipment. The die-cutting stacking knife process refers to that after the product is formed once, the die-cutting waste is introduced into the composite material again and die-cut into the same material or other materials again by adding a knife; compared with the traditional die-cutting process, the die-cutting process of the present application only requires one set of tapes. During the tape conveying process, the tapes are cut into multiple groups, and then the multiple groups of tapes are guided to fit with the corresponding material tapes respectively, so that one set of die-cutting equipment can produce multiple groups of products at the same time. On the one hand, the utilization rate of the tape raw materials is greatly improved, and on the other hand, the product production efficiency is improved and the production cost is reduced, thereby effectively increasing the market competitiveness of the company's products.
[0018] Reference Figure 1 The die-cutting device includes a wall 1, in which a driving device for driving the entire device is arranged. The driving device is a motor, and the entire device is driven by the motor.
[0019] The arrangement wall 1 is provided with a material belt roller group, a tape roller shaft 3, a slitting roller group 4, a die-cutting roller group, a pressing roller group, a guide roller shaft 6 and a receiving roller group.
[0020] In this embodiment, the number of tape cuts in one group is set to four groups. Of course, the number of tape cuts can also be set to six groups, eight groups, etc. according to production conditions, and the number of roller groups in the die-cutting equipment can be made corresponding. This embodiment takes the die-cutting equipment with two product production lines as an example.
[0021] The material belt roller group includes a first material belt roller shaft 2 and a second material belt roller shaft 5. The first material belt roller shaft 2 and the second material belt roller shaft 5 are sleeved with a raw material disk for winding the material belt; the adhesive tape roller shaft 3 is sleeved with a tape disk for winding the adhesive tape material belt. The first material belt roller shaft 2 and the adhesive tape roller shaft 3 are located at the front end of the production line, and the adhesive tape roller shaft 3 is relatively located above the first material belt roller shaft 2.
[0022] Along the running direction of the material strip, the slitting roller set 4 is arranged behind the first material strip roller shaft 2 and the adhesive tape roller shaft 3. The slitting roller set 4 includes a slitting roller shaft 41 and a pressure roller shaft 42 arranged in an up-and-down manner, the slitting roller shaft 41 is relatively located above the pressure roller shaft 42, and three groups of annular cutting blades 43 are arranged on the outer surface of the slitting roller shaft 41 at intervals.
[0023] The die-cutting roller group, the pinch roller group and the receiving roller group are set as two groups, and the two groups of die-cutting roller groups, the pinch roller group and the receiving roller group are respectively named as the first and the second, wherein the first die-cutting roller group 71, the first pinch roller group 81 and the first receiving roller group 91 are set as the first production line, and are sequentially distributed behind the slitting roller group 4. The second material belt roller shaft 5, the guide roller shaft 6, the second die-cutting roller group 72, the second pinch roller group 82 and the second receiving roller group 92 are set as the second production line, and are sequentially distributed behind the slitting roller group 4, and the second material belt roller shaft 5 is located below the guide roller shaft 6.
[0024] Both sets of die-cutting rollers are provided with die-cutting knives for cutting the adhesive tape passing through the die-cutting rollers; the pressing roller set is used for pressing the adhesive tape and the material tape to flatly attach the two together.
[0025] A positioning retaining ring 61 is detachably mounted on the guide roller 6. The positioning retaining ring 61 is used to position and correct the material passing through the guide roller 6 to prevent the material from being offset. The positioning retaining ring 61 can be detachably mounted by countersunk screws, so that the mounting position of the positioning retaining ring 61 on the guide roller 6 can be flexibly adjusted. The number of guide rollers 6 can be arranged in multiple groups, distributed in front of the second die-cutting roller group 72, so as to more carefully guide the direction of the tape, make the tape fitting position more accurate, and ensure smooth production of the product.
[0026] The two sets of receiving rollers pull the material strips respectively during the rotation process and finally rewind them for recovery.
[0027] When the die-cutting equipment is working, the first material tape wound on the first material tape roller 2 and the tape wound on the tape roller 3 enter the slitting roller group 4 together, and the cutting blade 43 die-cuts the tape passing between the slitting roller group 4, so that the original group of tapes is cut into four groups of tapes, and the four groups of tapes are named first, second, third and fourth tapes in sequence, among which the first and fourth tapes are located at the outermost sides of the original tape, just corresponding to the two side edges of the first material tape, and under the action of the slitting roller 41 and the pressure roller 42, the first and fourth tapes are initially attached to the first material tape, and flow to the first production line together with the first material tape, and the second and third tapes flow to the second production line under the guidance of the guide roller 6 and the positioning retaining ring 61.
[0028] The production process of the first production line is that the first and fourth adhesive tapes and the first material tape enter the first die-cutting roller group 71, and under the action of the die-cutting knife of the first die-cutting roller group 71, the adhesive tape on the first material tape is die-cut in sections to obtain the finished product, and then it flows to the first clamping roller group 81, and the first and fourth adhesive tapes and the first material tape are pressed together flatly to avoid product bubbles and other defects, and finally they are rolled up onto the first receiving roller shaft, and the first receiving roller shaft provides traction for the first material tape to move forward.
[0029] The production process of the second production line is as follows: the second material tape wound on the second material tape roller 5 enters the second die-cutting roller group 72, and the second and third adhesive tapes pass through the slitting roller group 4 and then pass through the positioning retaining ring 61 of the guide roller 6. Under the guidance of the positioning retaining ring 61, the second and third adhesive tapes are respectively located on both sides of the second material tape, and enter the second die-cutting roller group 72 together with the second material tape. Under the action of the die-cutting knife of the second die-cutting roller group 72, the adhesive tape on the second material tape is die-cut in sections to obtain the finished product, and then it flows to the second clamping roller group 82, and the second, third adhesive tapes and the second material tape are pressed together flatly, and finally rolled up onto the second receiving roller shaft, and the second receiving roller shaft provides traction for the second material tape to move forward.
[0030] This production equipment cuts large-size tapes into four groups and adds its own roller groups to form two product production lines. The four groups of tapes are introduced into the production lines to produce products. This not only improves the utilization rate of the tapes, but also reuses the original tape scraps, greatly reducing product production costs. The two production lines also double the product production efficiency, greatly improving the competitiveness of the company's products and contributing to the healthy development of the enterprise.
