Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, specifically a dual-track shaping and bag-breaking device. Background Technology

[0002] Tobacco materials refer to the various materials used in processing or packaging cigarettes, with tobacco leaves being the most crucial raw material. Tobacco leaves are generally processed into shredded tobacco at the production site through initial drying, re-drying, and fermentation, before being transported to cigarette factories for production. Therefore, tobacco leaves are usually delivered in bags, and the initial step in cigarette production is to break open these bags.

[0003] In existing technology, this process is completed by a bag-breaking machine. As a mechanical device for automatically dismantling large-capacity bagged materials, the bag-breaking machine's driving blades directly act on the surface of the packaging bag, destroying it through shearing and tearing. However, conventional bag-breaking machines often damage the contents while breaking the packaging bag, which is detrimental to the subsequent use of the tobacco raw materials. Ideally, the breaking process should preserve the original state of the tobacco bale as much as possible, only causing a certain degree of damage to the packaging bag to facilitate subsequent manual unloading. Furthermore, current conventional bag-breaking machines lack effective solutions for the problems of material spillage and dust dispersion. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is how to design a bag-breaking device that can complete the bag-breaking process while the cigarette pack is in a shaped state as much as possible.

[0005] The second technical problem that this utility model aims to solve is that conventional bag-breaking machines lack an effective solution to the problems of material scattering and dust dispersion.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0007] A dual-track shaping and bag-breaking device includes tracks, a pressing mechanism, and a bag-breaking mechanism. Two parallel tracks are provided, and the pressing mechanism is slidably connected to the tracks. The pressing mechanism includes a trolley, a pressure plate, springs, and an electric cylinder. The trolley slides with the tracks, the pressure plate is located below the trolley, and several springs connect between the pressure plate and the trolley. An electric cylinder is connected to the bottom of the trolley, and its free end is connected to the pressure plate. The bag-breaking mechanism includes conical blades, a support, a pressure frame, a main shaft, and a first motor. The support is fixedly connected to the lower end of the pressure plate, and the pressure frame is fixedly connected to the lower end of the support. The main shaft is rotatably connected inside the pressure frame, and several conical blades are fixedly mounted on the main shaft. The first motor is fixedly connected to the pressure frame and is drively connected to the main shaft.

[0008] Preferably, the device also includes a storage compartment, with the track fixedly installed inside the compartment, the movement of the trolley entirely within the compartment, and the packaging bag located below the pressure frame.

[0009] Preferably, a conveyor is also included, which is located inside the silo and whose travel stroke is below that of the trolley.

[0010] Preferably, pressure rollers and clamps are provided above the conveyor.

[0011] Preferably, a bulk material output pipe is provided at the lower end of the silo body.

[0012] Preferably, a bulk material storage pipe is provided at the lower end of the silo body. The bulk material storage pipe includes a pipe shell, an auger is rotatably connected in the pipe shell, a second motor is fixedly connected to the outside of the pipe shell, the second motor is driven by the auger, and a storage box is fixedly connected to the side of the pipe shell, with the auger extending into the storage box.

[0013] Preferably, several compressed air nozzles facing the conveyor are installed inside the chamber.

[0014] Preferably, a negative pressure pipe is also included, and several connecting covers are provided on the negative pressure pipe, the connecting covers being connected to the top of the silo body.

[0015] In the above technical solution, the two tracks are arranged in parallel, and the trolley of the pressing mechanism is mounted on them, allowing the trolley to slide along the two tracks for positioning the bag-breaking mechanism. When positioned directly above the packaging bag, the electric cylinder drives the pressure plate to press down, thereby pressing the pressure frame on the support onto the packaging bag, which restricts and shapes the bag. On this basis, the first motor drives the main shaft to rotate, causing the conical blade on the main shaft to cut and tear the packaging bag, achieving the purpose of breaking the bag. After the bag is broken, the first motor stops, the electric cylinder resets, and the spring assists in the reset.

[0016] In the preferred technical solution, a closed silo is used as the working space, which encloses the bag-breaking process and mitigates dust dispersion. Bagged raw materials are fed via a conveyor; during feeding, pressure rollers along the conveyor's path provide pre-shaping. When the material reaches the target location, the conveyor pauses, and clamps secure the packaging bags. Furthermore, a bulk material output pipe can be added to the silo to directly discharge any loose material; alternatively, a bulk material storage pipe can be added. When loose material falls into the storage pipe's casing, a second motor-driven auger pushes the material into a storage box beside the casing for collection. Additionally, compressed air nozzles can be added to intermittently spray air towards the conveyor to promote material descent. To further overcome dust issues, a negative pressure pipe can be added. The outer end of the negative pressure pipe connects to an exhaust fan, and the inner end connects to the silo via a connecting cover, drawing dust into the negative pressure pipe, where it can be collected by a cloth bag.

[0017] This utility model provides a dual-track shaping and bag-breaking device. The technical solution uses a feedable and positionable pressure frame to restrict and shape the bagged material, and then the conical blade inside the pressure frame performs the bag breaking. Based on the above technical solution, a closed silo is used for operation, which alleviates the problem of dust dispersion. Attached Figure Description

[0034] In the above technical solution, the double tracks 1 are arranged in parallel, and the trolley 4 of the pressing mechanism 2 is mounted on them, so that the trolley 4 can slide along the double tracks 1 to position the bag breaking mechanism 3. When it is positioned directly above the packaging bag, the electric cylinder 7 drives the pressure plate 5 to press down, so that the pressure frame 10 on the bracket 9 presses down on the packaging bag, which restricts and shapes the packaging bag. On this basis, the first motor 12 drives the main shaft 11 to rotate, so that the conical blade 8 on the main shaft 11 cuts and tears the packaging bag to achieve the purpose of breaking the bag. After the bag is broken, the first motor 12 stops, the electric cylinder 7 resets, and the spring 6 assists in the reset.

[0035] Example 2

[0036] A dual-track shaping and bag-breaking device, such as Figures 1-6As shown, the device includes a track 1, a pressing mechanism 2, and a bag-breaking mechanism 3. The track 1 consists of two parallel tracks, with the pressing mechanism 2 slidably connected to each other. The pressing mechanism 2 includes a trolley 4, a pressure plate 5, springs 6, and an electric cylinder 7. The trolley 4 slides with the track 1, and the pressure plate 5 is located below the trolley 4. Several springs 6 are connected between the pressure plate 5 and the trolley 4.

[0037] In the above technical solution, a closed silo 13 is used as the working space, which covers the bag-breaking process and alleviates the problem of dust scattering. Bagged raw materials can be fed through the conveyor 21; during the feeding process, the pressure rollers 14 along the conveyor 21 play a certain role in pre-shaping. When the conveyor reaches the target point, the conveyor 21 stops, and the packaging bag can be pre-fixed by the clamp 15. In addition, a bulk material output pipe 16 can be added to the silo 13 to directly discharge the scattered fragments; a bulk material temporary storage pipe 17 can also be added to the silo 13. When the fragments fall into the tube shell 18 of the bulk material temporary storage pipe 17, the auger 19 driven by the second motor 20 pushes the fragments into the temporary storage box next to the tube shell 18 for collection. In addition, compressed air nozzles 22 can be added to intermittently spray towards the conveyor 21 to promote the falling of bulk materials. To further overcome the dust problem, a negative pressure pipe 24 can be added.
