Description

Technical Field

[0001] This utility model relates to the field of die-cutting device technology, specifically a rapid die-cutting device for pet food bags. Background Technology

[0002] Food bag die-cutting equipment is one of the most common packaging bag processing equipment in the existing technology. The common working method is to place the prepared material on the worktable of the die-cutting machine (automatic transmission or manual placement), then start the die-cutting machine, and the mold will automatically press down to cut the material according to the designed shape, so as to cut it into packaging bags of the target shape.

[0003] However, the working principle of such die-cutting devices in the existing technology is similar to that of stamping. Each time a die is cut, the entire device needs to stop the transmission of plastic film to wait for the die-cutting work. The transmission can only continue after the die-cutting is completed. As a result, the operation of the entire device is intermittent, which seriously affects the working efficiency of the device. Therefore, an improved pet food bag rapid die-cutting device is needed to address this problem. Utility Model Content

A first telescopic rod is fixedly provided at the upper end of one side inside the die-cutting chamber, a first fixing ring is fixedly provided at the movable end of the first telescopic rod, a first roller is movably arranged between the first fixing rings via bearings, a heating frame is fixedly provided on the surface of the first roller, a second telescopic rod is fixedly provided inside the die-cutting chamber on one side of the first telescopic rod, a second fixing ring is fixedly provided at the movable end of the second telescopic rod, a second roller is movably arranged between the second fixing rings via bearings, and a cutting frame is fixedly provided on the outer surface of the second roller.

[0006] Preferably, the first fixing ring and the surface of the first roller are provided with a power supply mechanism for supplying power to the heating frame. The power supply mechanism includes a conductive ring, a conductive post, and a conductive sheet. A conductive ring is fixedly disposed on one side of the surface of the first roller, and a conductive post is fixedly disposed on the outer surface of the first fixing ring. A conductive sheet is sleeved on the outer side of the conductive post, and the outer surface of the lower end of the conductive sheet is in contact with the outer surface of the conductive ring. Since the heating frame of this device needs power to ensure that the heating frame heats up during use, it can heat the plastic film so that the two layers of plastic film are heated and bonded to form a three-sided seal. The conductive sheet and the conductive ring of this device can work together to form a rotational power supply function. When using this device, only power needs to be supplied to the conductive post, and the current can be transmitted through the conductive sheet to the conductive ring and then to the heating frame. In this way, power can be supplied no matter how the first roller rotates. At the same time, the conductive sheet of this device is a consumable part, and it can be removed and replaced after the device has been used for a long time.

[0007] Preferably, the conductive ring is electrically connected to the heating frame, and the conductive ring can supply power to the heating frame. When the heating frame rotates during use, the conductive ring will also rotate, so there is no need to worry about the cable tangling problem.

[0008] Preferably, the outer surface of the conductive post is provided with a fixing screw that can be screwed in by threads. Tightening the fixing screw can fix the conductive sheet, and the conductive sheet can be removed and replaced at any time when needed.

[0009] Preferably, the die-cutting chamber has a limiting roller movably installed at the lower end of both the first roller and the second roller via a rotating shaft. The limiting roller can limit the lower end of the packaging bag film, so that the first roller and the second roller can press against the surface of the packaging bag film.

[0010] Preferably, both the first and second telescopic rods are equipped with springs inside. The springs can push the first and second telescopic rods to extend, thereby pushing the first and second rollers to press against the surface of the packaging bag film.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a roller pressing method to seal the edges of the plastic film first, and then perform die cutting. The whole process does not require stopping the machine. The film can be continuously transferred from the lower surface of the first roller and the second roller, which can improve the overall processing efficiency of the device.

[0013] 2. When using this utility model, the heating frame of this device requires power to ensure that the heating frame heats up so that the plastic film can be heated and the two layers of plastic film can be heated and bonded to form a three-sided seal. The conductive sheet and conductive ring of this device work together to form a rotational power supply function. When using this device, only power needs to be supplied to the conductive column, and the current can be transferred through the conductive sheet to the conductive ring and then to the heating frame. In this way, power can be supplied no matter how the first roller rotates, so as to avoid cable tangling. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a rapid die-cutting device for pet food bags, including a die-cutting chamber 1. The die-cutting chamber 1 is equipped with a die-cutting mechanism for die-cutting packaging bags. The die-cutting mechanism includes a first telescopic rod 2, a first fixing ring 3, a first roller 4, a heating frame 5, a second telescopic rod 6, a second fixing ring 7, a second roller 8, and a cutting frame 9. The first telescopic rod 2 is fixedly installed on the upper end of one side inside the die-cutting chamber 1. The first fixing ring 3 is fixedly installed on the movable end of the first telescopic rod 2. The first roller 4 is movably installed between the first fixing rings 3 through bearings. The heating frame 5 is fixedly installed on the surface of the first roller 4. The second telescopic rod 6 is fixedly installed on one side of the first telescopic rod 2 inside the die-cutting chamber 1. The second fixing ring 7 is fixedly installed on the movable end of the second telescopic rod 6. The second roller 8 is movably installed between the second fixing rings 7 through bearings. The cutting frame 9 is fixedly installed on the outer surface of the second roller 8.

[0021] The first fixing ring 3 and the surface of the first roller 4 are provided with a power supply mechanism for supplying power to the heating frame 5. The power supply mechanism includes a conductive ring 10, a conductive post 11, and a conductive sheet 12. A conductive ring 10 is fixedly disposed on one side of the surface of the first roller 4, and a conductive post 11 is fixedly disposed on the outer surface of the first fixing ring 3. A conductive sheet 12 is sleeved on the outer side of the conductive post 11. The outer surface of the lower end of the conductive sheet 12 is in contact with the outer surface of the conductive ring 10. Since the heating frame 5 of this device needs power supply during use to ensure that the heating frame 5 heats up, it can heat the plastic film so that the two layers of plastic film are heated and bonded to form a three-sided seal. The conductive sheet 12 and the conductive ring 10 of this device can cooperate to form a rotational power supply function. When using this device, only the conductive post 11 needs to be powered to transmit the current through the conductive sheet 12 to the conductive ring 10 and then to the heating frame 5. In this way, power can be supplied no matter how the first roller 4 rotates. At the same time, the conductive sheet 12 of this device is a consumable part. After the device has been used for a long time, the conductive sheet 12 can be removed and replaced.

[0022] The conductive ring 10 is electrically connected to the heating frame 5. The conductive ring 10 can supply power to the heating frame 5. When the heating frame 5 rotates during use, the conductive ring 10 will also rotate, so there is no need to worry about the cable tangling problem.

[0023] The outer surface of the conductive post 11 is provided with a fixing screw 13 by means of threaded engagement. Tightening the fixing screw can fix the conductive sheet 12, and the conductive sheet 12 can be removed and replaced at any time when needed.

[0024] Inside the die-cutting chamber 1, limit rollers are movably installed at the lower ends of the first roller 4 and the second roller via rotating shafts. The limit rollers can limit the lower end of the packaging bag film so that the first roller 4 and the second roller can be squeezed onto the surface of the packaging bag film.

[0025] Both the first telescopic rod 2 and the second telescopic rod 6 are equipped with springs. The springs can push the first telescopic rod 2 and the second telescopic rod 6 to extend, thereby pushing the first roller 4 and the second roller to press against the surface of the packaging bag film.

[0026] Working principle: This device sequentially conveys two layers of plastic film for packaging bags that need to be die-cut and sealed through the lower ends of the first roller 4 and the second roller. As the first roller 4 rotates, the heating frame 5 rolls around the surface of the plastic film. The high temperature of the heating frame 5 melts the plastic film, causing the two layers of plastic film to heat and adhere together, forming a three-sided seal. Subsequently, as the plastic film is conveyed, it enters the space between the second rollers, where the cutting frame 9 on the surface of the second roller can die-cut the plastic film to form a rectangular packaging bag. This rectangular packaging bag is sealed on three sides, thus completing the die-cutting work. This device uses a roller pressing method to seal the plastic film first and then perform die-cutting. The entire process does not require stopping the machine; the film is simply continuously conveyed through the lower ends of the first roller 4 and the second roller, which improves the overall processing efficiency of the device.

[0027] Furthermore, during the use of this device, the heating frame 5 requires power to ensure its temperature rise, thus heating the plastic film and causing the two layers of plastic film to heat and adhere together to form a three-sided seal. The conductive sheet 12 and the conductive ring 10 of this device work together to form a rotational power supply function. When using this device, only power needs to be supplied to the conductive column 11, and the current will be transmitted through the conductive sheet 12 to the conductive ring 10 and then to the heating frame 5. In this way, power can be supplied no matter how the first roller 4 rotates, so as to avoid cable tangling. At the same time, the conductive sheet 12 of this device is a consumable part, and after the device has been used for a long time, the conductive sheet 12 can be removed and replaced.
