Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot cutting technology for tapes, labels, foams, etc. in the packaging industry, specifically a pulse-type hot melt cutting foam mechanism. Background Technology
[0002] The pulse-type hot-melt foam cutting mechanism is an advanced foam processing equipment. Its core function is to achieve efficient cutting of foam materials through pulse-type hot-melt technology. Utilizing the principle of pulse heating, this mechanism can rapidly heat to the required temperature in a short time, thus performing precise hot-melt cutting of the foam. Its unique design makes the hot-melt cutting process more stable and efficient, effectively avoiding problems such as burrs and burnt edges that may occur in traditional cutting methods. Furthermore, the pulse-type hot-melt foam cutting mechanism also has excellent adjustability, allowing for flexible adjustments according to different specifications and thicknesses of foam materials, ensuring cutting quality and efficiency. Overall, this mechanism has significant advantages in improving foam processing precision and production efficiency, and is widely used in the production of various foam products. Based on actual usage, the existing pulse-type hot melt cutting foam mechanism has some drawbacks. For example, when cutting packaging rolls to a fixed length, the hot cutting speed is not fast enough, the dimensions are prone to deviation, and the cuts are uneven and sticky. Therefore, we have improved the existing technology based on actual usage. Utility Model Content

[0028] Working principle: First, turn on the pulse controller switch 32 of the control device to power on the pulse controller 2. Set the corresponding temperature, time, and distance dimensions on the pulse controller interface and press the start button. Then, the take-up motor 36 and the feed motor 37 of the take-up and feed-down device rotate simultaneously. The foam strip 11 moves a certain distance clockwise under the drive and support of the take-up wheel 6, the follower wheel support block 8, the follower wheel shaft 10, the follower wheel 9, the feed idler wheel 29, and the feed wheel 7. At this time, the swing cylinder 19 of the swing pressing device retracts, driving the cylinder pull head 26, the pull head shaft 25, the swing rod fixing pin 24, and the pressing wheel swing rod 23 to lift upward. Under the action of leverage, the pressing wheel 22 moves downward to press the foam strip 11 tightly against the guide groove of the foam strip support plate 4. Then, the hot cutting cylinder 12 of the hot cutting device extends downward, driving the heat insulation block 13 and the conductive block 14 and the hot cutting head 15 of the conductive device to press down and contact the foam strip 11. At this time, the pulse control... The device 2 outputs electrical energy to the hot cutting head 15 through the cable terminal block 38, cable 1 30, cable 2 31, and conductive block 14 of the conductive device to start heating. The real-time temperature of the hot cutting head 15 is fed back to the pulse controller 2 through the temperature sensing wire 17 and temperature sensing wire plug 18 of the temperature sensing device. The hot cutting head 15, which has a certain temperature, cuts the foam tape 11 into a certain depth under the thrust of the hot cutting cylinder 12. When the set temperature and set time are reached, the cooling solenoid valve 34, cooling connector 1 33, and cooling connector 2 16 of the head cooling device start to blow air to cool the hot cutting head 15. When the set temperature is reached, the hot cutting head retracts, which drives the hot cutting head 15 to move upward away from the foam tape 11. Then the take-up motor 36 and feed motor 37 of the take-up and feed-down device rotate again, pulling the foam tape 11 to move a certain distance in a clockwise direction. The hot cutting cylinder 12 of the hot cutting device extends again, and the movement and hot cutting operation are repeated.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
